TECHNICAL FIELD

[0002]The present disclosure relates to the technical field of cleaning devices, in particular to a cleaning system.

BACKGROUND

[0003]A vacuum cleaner includes a dust cup. In order to clean dust in the dust cup, the vacuum cleaner is equipped with a base station. When in use, the vacuum cleaner is placed on the base station, and the dust in the dust cup is collected by the base station. In the related art, after the dust in the dust cup is collected by the base station, a user may need to manually close a cover door of the dust cup, which leads to a poor user experience.

SUMMARY

[0004]In view of this, embodiments of the present disclosure are intended to provide a cleaning system that facilitates cleaning of dust in a dust cup.

[0005]In order to achieve the above aim, the technical solutions of the embodiments of the present disclosure are realized as follows.

[0010]During entry of the dust cup into the dust collection bin, the unlocking member drives the locking mechanism to unlock the cover door, and during withdrawal of the dust cup from the dust collection bin, the return member drives the locking mechanism to lock the cover door.

[0011]The embodiments of the present disclosure disclose a cleaning system. To clean foreign matters in the dust collection chamber, the dust cup can be inserted into the dust collection bin, and then the unlocking member can drive the locking mechanism to unlock the cover door to allow the dust discharge opening to be opened. In this way, the dust in the dust collection chamber can enter into the dust collection bin through the dust discharge opening to allow the dust collection chamber to be cleaned, which provides a good dust storage space for the next cleaning of the surface to be cleaned. When the foreign matters in the dust collection chamber have been cleaned or the surface is to be cleaned, the dust cup can be withdrawn from the dust collection bin. At this time, the return member drives the locking mechanism to lock the cover door, to allow the dust discharge opening to be automatically closed. In this way, the user can be prevented from getting his/her hands dirty due to a manually closing of the cover door, which provides a high degree of automation, and good user experience.

DETAILED DESCRIPTION

[0024]It should be noted that embodiments in the present disclosure and technical features in the embodiments can be combined with each other without conflict, and the detailed description in the embodiments should be understood as an explanation of the purpose of the present disclosure, and should not be regarded as an undue limitation of the present disclosure.

[0025]The present disclosure will be further described in detail with reference to the accompanying drawings and specific embodiments. The expressions such as “first”, “second” and the like in the present disclosure are for descriptive purposes only, and should not be understood as indicating or implying relative importance thereof or implicitly including at least one feature.

[0026]Embodiments of the present disclosure provide a cleaning system. With reference to FIG. 1 to FIG. 12, the cleaning system 100 includes a vacuum cleaner 1, an unlocking member 22, and a base station 2. The vacuum cleaner 1 includes a dust cup 11 and a locking mechanism 12. The dust cup 11 includes a cup body 111 and a cover door 112. The cup body 111 is provided with a dust collection chamber 111a and a dust discharge opening 111b communicating with the dust collection chamber 111a. The cover door 112 selectively opens or closes the dust discharge opening 111b. The locking mechanism 12 is arranged on the dust cup 11 and is configured to lock or unlock the cover door 112.

[0027]The base station 2 includes a base body 21 and a return member 23, and the base body 21 is provided with a dust collection bin 21a. During the entry of the dust cup 11 into the dust collection bin 21a, the unlocking member 22 drives the locking mechanism 12 to unlock the cover door 112. During the withdrawal of the dust cup 11 from the dust collection bin 21a, the return member 23 drives the locking mechanism 12 to lock the cover door 112.

[0028]When the vacuum cleaner 1 is cleaning a surface to be cleaned, the locking mechanism 12 locks the cover door 112 to close the dust discharge opening 111b. In this way, foreign matters such as dust or garbage in the dust collection chamber 111a can be prevented from leaking out of the dust cup 11 through the dust discharge opening 111b.

[0029]In the cleaning system 100 provided by the embodiments of the present disclosure, to clean the foreign matters in the dust collection chamber 111a, the dust cup 11 can be inserted into the dust collection bin 21a, and then the unlocking member 22 can drive the locking mechanism 12 to unlock the cover door 112 to allow the dust discharge opening 111b to be opened. In this way, the dust in the dust collection chamber 111a can enter into the dust collection bin 21a through the dust discharge opening 111b to allow the dust collection chamber 111a to be cleaned, which provides a good dust storage space for the next cleaning of the surface to be cleaned, and provides a high degree of automation. When the foreign matters in the dust collection chamber 111a have been cleaned or the surface is to be cleaned, the dust cup 11 can be withdrawn from the dust collection bin 21a. At this time, the return member 23 drives the locking mechanism 12 to lock the cover door 112, to allow the dust discharge opening 111b to be automatically closed. In this way, the user can be prevented from getting his/her hands dirty due to a manually closing of the cover door, which provides a high degree of automation, and good user experience.

[0030]It should be noted that the surface to be cleaned includes but is not limited to a floor, or a surface of a table, or the like.

[0031]In some embodiments, the dust collection bin 21a described herein is a bin or chamber for accommodating the dust cup 11. In particular, the dust collection bin 21a may be a dust collection air duct, or a dust collection portion, or the like of the base station 2.

[0032]In some embodiments, the shape of the dust cup 11 is not limited, for example, it may be a hollow cylinder or a cone or the like.

[0033]In some embodiments, the vacuum cleaner 1 may be a handheld vacuum cleaner 1. First, the handheld vacuum cleaner 1 is small in volume and light in weight. Second, the handheld vacuum cleaner has wide applicability, and the handheld vacuum cleaner 1 can clean various cleaning occasions such as bottom plates, carpets, sofas and mattresses.

[0034]In some embodiments, the locking mechanism 12 includes a locking body 121 arranged on the dust cup 11, and a locking structure 122 arranged on the cover door 112. The locking body 121 cooperates with the locking structure 122 to selectively lock or unlock the cover door 112. In this way, when the dust cup 11 is inserted into the dust collection bin 21a, the unlocking member 22 can drive the locking body 121 to be separated from the locking structure 122 to unlock the cover door 112, to allow the dust discharge opening 111b to be opened. When the dust cup 11 is withdrawn from the dust collection bin 21a, the return member 23 drives the locking body 121 and the locking structure 122 to be locked to lock the cover door 112, to allow the dust discharge opening 111b to be automatically closed.

[0035]In some embodiments, with reference to FIG. 2 to FIG. 8, the cover door 112 includes a rotating portion 1122 rotatably connected with the cup body 111. The cover door 112 includes a cover body 1121 and the rotating portion 1122, and the locking structure 122 is arranged on the cover body 1121. One end of the rotating portion 1122 is connected with the cover body 1121, and another end of the rotating portion 1122 extends toward a direction close to the cup body 111. In some embodiments, the dust cup 11 includes a rotating shaft 114 and a fixed member 113, and the fixed member 113 is fixed on the cup body 111. The fixed member 113 is provided with a mounting groove 113a, and a first mounting opening 113b and a second mounting opening 113c are formed through a side surface of the fixed member 113 close to the base body 21 and a side surface of the fixed member 113 close to the cover body 1121 respectively. Each of the first mounting opening 113b and the second mounting opening 113c communicates with the mounting groove 113a. The rotating portion 1122 is arranged in the mounting groove 113a. A first hole is formed on a wall of the mounting groove 113a, a second hole is formed on the rotating portion 1122, and the rotating shaft 114 passes through the first hole and the second hole. In this way, the cover door 112 can be rotated through the rotating shaft 114 and the holes. On the one hand, components for the rotating the rotating shaft 114 and the holes have a small number, are easy to maintain, and have high reliability. On the other hand, the rotation of the rotating shaft 114 and the holes does not use complex hydraulic and pneumatic systems, the maintenance cost is low, and it is easy to realize.

[0036]During the withdrawal of the dust cup 11 from the dust collection bin 21a, the return member 23 abuts against the rotating portion 1122 to allow the cover door 112 to be rotated toward a direction close to the cup body 111, to drive the locking mechanism 12 to perform locking. In some embodiments, when the foreign matters in the dust collection chamber 111a is cleaned or the surface is to be cleaned, the dust cup 11 can be withdrawn from the dust collection bin 21a. During the start of the withdrawal, the return member 23 located on the base body 21 will abut against the rotating portion 1122. When the withdrawal continues, a force opposite to the withdrawal direction is applied to the rotating portion 1122 by the return member 23. Due to the presence of the rotating shaft 114, with the rotating shaft 114 as a fulcrum, the force can pry a side of the cover body 1121 away from the rotating portion 1122 to allow it to be rotated about the rotating shaft 114, that is, to be rotated toward the direction close to the cup body 111. In this way, the locking structure 122 and the locking body 121 can cooperate with each other, to perform the locking.

[0037]In some embodiments, the shape of the rotating portion 1122 is not limited, for example, it may be a cube or a cuboid or the like.

[0038]In some embodiments, with reference to FIG. 5 and FIG. 9, the locking body 121 is located at a portion of the cup body 111 away from the rotating portion 1122. That is, the locking body 121 may be located on one side of the cup body 111 and the fixed member 113 may be located on another opposite side of the cup body 111. In this way, the locking body 121 can be returned during the rotation of the cover door 112 driven by the return member 23, which avoids the interference.

[0039]In some embodiments, the locking body 121 may be arranged a lap around the cup body 111.

[0040]In some embodiments, with reference to FIGS. 1, 6 and 9, the number of the locking body 121 and the number of the locking structure 122 are not limited. For example, there may be two locking bodies 121 and two the locking structures 122. The two locking bodies 121 are arranged on the cup body 111 and are spaced apart from each other along an axis extending direction of the rotating shaft 114, and the two locking structures 122 are arranged on the cover body 1121 and are spaced apart from each other along the axis extending direction of the rotating shaft 114. Each of the two locking bodies 121 cooperates with a respective one of the two locking structures 122, to improve the connection strength between the cover door 112 and the dust cup 11. In this way, it is not easy to open the cover door 112 during the cleaning work of the vacuum cleaner 1.

[0041]In some embodiments, with reference to FIGS. 2, 3, 4 and 12, the return member 23 abuts against a circumferential surface of the rotating portion 1122 in a state in which at least a part of the dust cup 11 is located in the dust collection bin 21a. Herein, the circumferential surface of the rotating portion 1122 refers to an end surface of the rotating portion 1122 away from the cover body 1121. When the dust cup 11 is located in the dust collection bin 21a, the cover door 112 is in an open state, and the return member 23 is in contact with the circumferential surface of the rotating portion 1122. When the dust cup 11 is withdrawn, a force opposite to the withdrawal direction will be applied to the circumferential surface by the return member 23. Due to the presence of the rotating shaft 114, this force will force the cover door 112 to rotate toward the direction close to the cup body 111. During the slow rotation of the cover door 112, the circumferential surface will be substantially parallel to the withdrawal direction, for example as shown in FIG. 2 to FIG. 4. After the circumferential surface is substantially parallel to the withdrawal direction, on the one hand, the cover door 112 will not be interfered with the return member 23, and the dust collection bin 21a can be withdrawn. On the other hand, the circumferential surface is substantially parallel to the withdrawal direction, which indicates that at this time the locking structure 122 and the locking body 121 can cooperate with each other to perform the locking.

[0042]In some embodiments, with reference to FIG. 1 and FIG. 12, an access opening 21b communicating with the dust collection bin 21a is formed on an upper surface of the dust collection bin 21a, and the dust discharge opening 111b is formed on a lower surface of the cup body 111. The dust cup 11 enters into and is withdrawn from the dust collection bin 21a in a vertical direction through the access opening 21b. In this way, to clean the foreign matters in the dust collection chamber 111a, the dust cup 11 can be inserted into the dust collection bin 21a along the vertical direction through the access opening 21b. On the one hand, the vacuum cleaner 1 is inserted into the base station 2 along the vertical direction, which can reduce the floor area of the cleaning system 100, and has high space utilization rate, and in addition, which is convenient for the user to perform an insertion or withdrawal operation. On the other hand, the access opening 21b is formed on the upper surface of the dust collection bin 21a and the dust discharge opening 111b is formed on the lower surface of the cup body 111, which allows the foreign matters in the dust collection chamber 111a to fall into the dust collection bin 21a located below the dust collection chamber 111a, and makes the cleaning to be relatively simple. On the other hand, after the unlocking member 22 drives the locking body 121 and the locking structure 122 to be separated from each other to unlock the cover door 112, the cover door 112 can be rotated by its own gravity about the rotating shaft 114 toward a direction away from the cup body 111, to allow the dust discharge opening 111b to be opened.

[0043]In some embodiments, the dust cup 11 includes a torsion spring, which is arranged around the rotating shaft 114 and configured to open the cover door 112. In this way, the rotating shaft 114 can be provided with a certain pre-tightening force, which reduces the situation in which the cover door 112 is opened mistakenly.

[0044]In some embodiments, with reference to FIGS. 2, 3, 4 and 12, a part of a circumferential wall surface of the dust collection bin 21a protrudes inwardly to form the return member 23. In some embodiments, a top wall surface of the dust collection bin 21a protrudes inwardly to block a part of the access opening 21b. The return member 23 is provided with a non-blocking groove 23a in which the rotating portion 1122 is not blocked. A lower surface of the return member 23 abuts against the rotating portion 1122 during the withdrawal of the dust cup 11 from the dust collection bin 21a. When the dust cup 11 enters into the dust collection bin 21a, the circumferential surface of the rotating portion 1122 is substantially parallel to a wall surface of the non-blocking groove 23a close to the dust cup 11, to allow the dust cup 11 to be lowered into the dust collection bin 21a. When the dust cup 11 is withdrawn from the dust collection bin 21a, the lower surface of the return member 23 will abut against the circumferential surface of the rotating portion 1122, to force the cover door 112 to rotate until the circumferential surface of the rotating portion 1122 is substantially parallel to the wall surface of the non-blocking groove 23a close to the cup body 111. In this way, the cover door 112 can be withdrawn from the dust collection bin 21a without structural interference. Here, the circumferential surface of the rotating portion 1122 is substantially parallel to the wall surface of the non-blocking groove 23a close to the cup body 111, which indicates that the dust discharge opening 111b has been substantially closed by the cover door 112, and the locking structure 122 and the locking body 121 have reached a position in which the locking structure 122 and the locking body 121 cooperate with each other, and the locking structure 122 and the locking body 121 are ready to cooperate with each other.

[0045]In some embodiments, with reference to FIGS. 1, 9 and 11, the locking body 121 is slidably arranged on an outer wall of the cup body 111. In this way, when the locking mechanism 121 is to be repaired or replaced, it can be operated directly from the outer wall of the cup body 111, which is convenient and efficient. The unlocking member 22 drives the locking body 121 to slide, to allow the locking body 121 to be separated from the locking structure 122. In this way, to clean the foreign matters in the dust collection chamber 111a, the dust cup 11 can be inserted into the base station 2, and the unlocking member 22 in the dust collection bin 21a will contact the locking body 121 arranged on the cup body 111 to drive the locking body 121 to slide, to allow the locking body 121 and the locking structure 122 to be separated from each other by relative movement thereof. In this way, the cover door 112 can be automatically unlocked. The dust discharge opening 111b is opened, and the foreign matters in the dust collection chamber 111a can enter into the dust discharge opening 111b through the dust collection bin 21a, to complete the cleaning of the foreign matters in the dust collection chamber 111a, which provides a high degree of automation, and good user experience.

[0046]In some embodiments, a fixing groove may be arranged on the cover body 1121, and the locking structure 122 may be fixed in the fixing groove, which provides a stable position for the cooperation of the locking body 121 with the locking structure 122.

[0047]In some embodiments, the locking structure 122 is bonded to the cover body 1121 by a viscous substance such as glue, which can avoid the arrangement of a groove on the cover body 1121 and can reduce damage to the cover body 1121.

[0048]In some embodiments, the locking body 121 cooperates with the locking structure 122 by magnetic attraction. In this way, the connection of the locking body 121 and the locking structure 122 can be made through the magnetic attraction without any external force, which is convenient in use, has simple and easy operation, and has high stability.

[0049]In some embodiments, the magnetic cooperation of the locking body 121 and the locking structure 122 includes, but is not limited to, the following forms. For example, each of the locking body 121 and the locking structure 122 may be a permanent magnet. For example, one of the locking body 121 and the locking structure 122 is a permanent magnet, and another one of the locking body 121 and the locking structure 122 is a ferromagnetic material such as iron, nickel or chromium. For example, each of the locking body 121 and the locking structure 122 may be an electromagnet. For example, one of the locking body 121 and the locking structure 122 is an electromagnet, and another one of the locking body 121 and the locking structure 122 is a material such as iron, nickel or chromium. For example, one of the locking body 121 and the locking structure 122 is an electromagnet, and another one of the locking body 121 and the locking structure 122 is a permanent magnet.

[0050]In some embodiments, one of the locking body 121 and the locking structure 122 is a snap, another one of the locking body 121 and the locking structure 122 is a slot, and the snap is snapped into the slot. In some embodiments, the locking body 121 may be a snap, and the locking structure 122 may be a slot. In this way, on the one hand, a connection manner of the snap and the slot has strong connection strength and stability, thus it is not easy to open the cover door 112 when the vacuum cleaner 1 is in operation. On the other hand, the connection manner of the snap and the slot makes the connection and disconnection of the dust cup 11 and the cover door 112 relatively simple. In other embodiments, the locking body 121 may be a slot and the locking structure 122 may be a snap.

[0051]In some embodiments, one of the locking body 121 and the locking structure 122 is a snap. In this way, the snap can be snapped directly to the cover door.

[0052]In some embodiments, with reference to FIGS. 2, 3, 4, 5, 8, 9, 10 and 11, an accommodating chamber 13a for accommodating the locking body 121 is formed on the dust cup 11. In some embodiments, the dust cup 11 includes a housing 13 connected with an outer peripheral surface of the cup body 111, and the housing 13 and the outer peripheral surface of the cup body 111 together define the accommodating chamber 13a. In some embodiments, the housing 13 may be arranged on a side of the cup body 111 away from the fixed member 113. The shape of the housing 13 is not limited. For example, the housing 13 may be a hollow cylindrical housing. In this way, the accommodating chamber 13a is substantially cylindrical. In other embodiments, the housing 13 may be a part of the cup body 111, that is, the housing 13 is integrally formed with the cup body 111, which can improve the connection strength of the housing 13 and the cup body 111.

[0053]The accommodating chamber 13a is provided with a communication opening 13b toward the cover door 112. That is, a bottom of the accommodating chamber 13a is provided with an opening. During the entry of the dust cup 11 into the dust collection bin 21a, the accommodating chamber 13a can communicate with the dust collection bin 21a through the communication opening 13b. An extension opening 13c communicating with the accommodating chamber 13a is arranged on a periphery of the housing 13, and a part of the locking body 121 is arranged in the accommodating chamber 13a. In this way, on the one hand, the locking body 121 can be protected to a certain extent, to improve the service life of the locking body 121. On the other hand, the part of the locking body 121 is arranged in the accommodating chamber 13a. In this way, when the unlocking member 22 drives the locking body 121 to slide during the entry of the dust cup 11 into the dust collection bin 21a, the accommodating chamber 13a can play a certain guiding role and a non-blocking role on the locking body 121, which avoids the situation in which the locking body 121 and the locking structure 122 cannot be separated from each other, and which provides good operation stability.

[0054]The locking body 121 cooperates with the locking structure 122 through the communication opening 13b. In an example in which the dust cup 11 enters into and is withdrawn from the dust collection bin 21a along the vertical direction, during the upward withdrawal of the dust cup 11 from the dust collection bin 21a along the vertical direction, the locking body 121 slides downwardly along the vertical direction due to its own gravity. In this way, a part of the locking body 121 will slide to the vicinity of the communication opening 13b, which provides a good cooperating position for subsequent contact with the locking structure 122.

[0055]A part of the locking body 121 passing through the extension opening 13c is configured to be in contact with the unlocking member 22. In an example in which the dust cup 11 is inserted downwardly along the vertical direction into the dust collection bin 21a, during the entry of the dust cup 11 into the dust collection bin 21a, the unlocking member 22 comes into contact with the part of the locking body 121 passing through the extension opening 13c, to drive a part of the locking body 121 located in the accommodating chamber 13a to slide upwardly, to in turn allow a part of the locking body 121 located in the communication opening 13b to enter into the accommodating chamber 13a. In this way, the locking body 121 is separated from the locking structure 122, the cover door 112 is unlocked, and the dust discharge opening 111b is opened.

[0056]In some embodiments, with reference to FIG. 1, a part of a circumferential wall surface of the dust collection bin 21a protrudes inwardly to form the unlocking member 22. In some embodiments, one end of the unlocking member 22 is connected with the circumferential wall surface of the dust collection bin 21a, and another end of the unlocking member 22 extends toward a direction close to the dust cup 11. That is, the wall surface of the dust collection bin 21a extends downwardly along the vertical direction, then protrudes toward the direction close to the dust cup 11 to form a step, and then extends downwardly along the vertical direction. In an example in which the dust cup 11 is inserted downwardly into the dust collection bin 21a, during the entry of the dust cup 11 into the dust collection bin 21a, the part of the locking body 121 passing through the extension opening 13c will come into contact with the step of the unlocking member 22 to prevent a downward movement of the locking body 121 along the vertical direction. In this way, a relative movement of the locking body 121 and the cover body 1121 occurs, to allow the part of the locking body 121 located in the communication opening 13b to be separated from the locking structure 122, and to allow the cover door 112 to be automatically unlocked. In this way, the formation of the unlocking member 22 in the dust collection bin 21a can lead to tidy appearance of the base station 2.

[0057]In some embodiments, with reference to FIGS. 1, 9, 10 and 11, the locking mechanism 12 includes an elastic structure 123 connected with the locking body 121. In some embodiments, the elastic structure 123 may be arranged in the accommodating chamber 13a. For example, one end of the elastic structure 123 is connected with a top wall of the accommodating chamber 13a, and another end of the elastic structure 123 is connected with a side of the locking body 121 away from the communication opening 13b. In this way, on the one hand, the elastic structure 123 can adopt the top wall of the accommodating chamber 13a as a support point to perform compression and elongation, to drive the locking body 121 to slide. On the other hand, by providing the elastic structure 123 in the accommodating chamber 13a, the elastic structure 123 can be protected to a certain extent, which can improve its service life.

[0058]The unlocking member 22 drives the locking body 121 to cause elastic deformation of the elastic structure 123. In an example in which the dust cup 11 is inserted downwardly into the dust collection bin 21a, during the entry of the dust cup 11 into the dust collection bin 21a, the part of the locking body 121 passing through the extension opening 13c will come into contact with an extension part of the unlocking member 22 to prevent a downward movement of the locking body 121. In this way, the locking body 121 compresses the elastic structure 123 upwardly, to allow the part of the locking body 121 located in the communication opening 13b to be separated from the locking structure 122, and to allow the cover door 112 to be automatically unlocked. In this way, with the arrangement of the elastic structure 123, a certain pretension force can be provided to reduce mistaken unlocking of the cover door 112 and improve the reliability of unlocking the cover door 112. In some embodiments, during the insertion of the dust cup 11 into the dust collection bin 21a, the part of the locking body 121 passing through the extension opening 13c may come into contact with a wall of the dust collection bin 21a, to allow the locking body 121 to be slid and to allow the cover door 112 to be unlocked in advance.

[0059]During the withdrawal of the dust cup 11 from the dust collection bin 21a, the elastic structure 123 recovers the elastic deformation to allow the locking body 121 to be returned. In an example in which the vacuum cleaner 1 enters into and is withdrawn from the dust collection bin 21a along the vertical direction, after the foreign matters in the dust collection chamber 111a enters into the dust collection bin 21a, during the upward withdrawal of the dust cup 11 from the dust collection bin 21a, the elastic structure 123 will recover the elastic deformation, to drive the locking body 121 to move downwardly. In this way, a part of the locking body 121 away from the elastic structure 123 will automatically approach the communication opening 13b, to provide a good position for a subsequent cooperation with the locking structure 122.

[0060]In some embodiments, the elastic structure 123 can be a spring. In this way, springs made of different materials can be selected according to different requirements to provide different pretension forces, which leads to high selectivity and low manufacturing cost.

[0061]In some embodiments, with reference to FIGS. 8 and 9, a bayonet 13d communicating with the accommodating chamber 13a is arranged on a peripheral of the housing 13, and a part of the locking body 121 is movably arranged at the bayonet 13d. Blocking provided by a wall below the bayonet 13d prevents the elastic structure 123 from fully releasing the pretension force. That is, in the unlocked state of the cover door 112, the elastic structure 123 maintains a certain pretension force within the accommodating chamber 13a. In this way, the stable operation of the locking body 121 can be ensured, which not only avoids the ejection of the locking body 121 from the communication opening 13b after the elastic structure 123 recovers the elastic deformation, but also increases a trigger pressure for the unlocking of the cover door 112, to reduce mistaken unlocking of the cover door 112.

[0062]In some embodiments, the bayonet 13d and the extension opening 13c are misaligned with each other along the vertical direction to avoid structural interference.

[0063]In some embodiments, with reference to FIGS. 2, 3, and 4 to 11, in a state in which the cup body 111 is located in the dust collection bin 21a, the unlocking member 22 may be located on one side of the cup body 111 and the return member 23 may be located on another opposite side of the cup body 111. In this way, structural interference can be avoided so that the action of the separation of the locking body 121 from the locking structure 122 driven by the unlocking member 22 and the action of the locking of the locking structure 122 and the locking body 121 driven by the return member 23 do not affect each other.

[0064]In some embodiments, the cleaning system 100 includes a motor arranged on the base station 2 and configured to suck gas from the dust collection bin 21a. The motor is started in a state in which the cup body 111 is located in the dust collection bin 21a. In some embodiments, the motor may be a suction motor, and the motor may be arranged on the base station 2. The motor may be connected with the dust collection bin 21a through a pipe to suction the gas in the dust collection bin 21a to allow the dust collection bin 21a to be in a negative pressure state. In this way, in the state in which the cup body 111 is located in the dust collection bin 21a, the unlocking member 22 drives the locking body 121 and the locking structure 122 to be separated from each other to unlock the cover door 112, and the motor is started to allow the cover door 112 to be automatically opened through a pressure difference between the dust collection chamber 111a and the dust collection bin 21a, to allow the dust collection chamber 111a to communicate with the dust collection bin 21a. In this way, foreign matters in the dust collection chamber 111a can be cleaned relatively quickly and cleanly.

[0065]In some embodiments, it is also possible to accelerate the blowing of the foreign matters from the dust collection chamber 111a into the dust collection bin 21a by blowing gas to the dust collection bin 21a at the dust collection chamber 111a.

[0066]In some embodiments, it is also possible in the dust collection chamber 111a.

[0067]In some embodiments, with reference to FIG. 12, a flange 21c extending toward the cup body 111 is formed in the dust collection bin 21a, and the flange 21c is configured to support the cup body 111 to prevent the cup body 111 from falling into the dust collection bin 21a, which may soil the cup body 111.

[0068]The foregoing is only preferred embodiments of the present disclosure, and is not intended to limit the present disclosure. Various modifications and variations may be made to the present disclosure for those skilled in the art.

[0069]All modifications, equivalent substitutions, improvements, etc. within the spirit and principles of the present disclosure are included in the scope of protection of the present disclosure.
