Toilet Deodorizing Device

TECHNICAL FIELD

[0001]The present disclosure relates to the technical field of toilet accessories, and more particularly to a toilet deodorizing device.

BACKGROUND

[0002]In the related art, to reduce odors generated during the use of a toilet, ventilation equipment, such as exhaust fans, is typically installed on bathroom windows or ceilings to expel odors from the bathroom. However, before the ventilation equipment can completely remove the odors, the odors may have already spread throughout the entire bathroom. As a result, this method of eliminating bathroom odors often fails to provide satisfactory results.

[0003]Furthermore, in certain situations, there may not be a suitable location to install ventilation equipment. For example, in bathrooms without windows, odors can only be discharged into the building's ventilation system, leading to the spread of odors to other spaces within the same building, thereby affecting other parts of the structure.

The First Embodiment

[0034]Referring to FIGS. 1 and 2, the first embodiment of the present disclosure discloses a toilet deodorizing device 10, which includes an air intake component 11, an air intake mechanism 13, and a ventilation and drainage assembly 15. The air intake component 11 includes a mounting portion 111 and an extension portion 113 connected to the mounting portion 111. The mounting portion 111 is arranged at a top edge of a toilet bowl 21, and the extension portion 113 extends into the interior of the toilet bowl 21. The extension portion 113 may extend partially or fully into the toilet bowl 21, including extending into the concave part of the toilet bowl 21a (refer to FIG. 1 and FIG. 3) or extending into the central part of the upper opening 21a1 of the toilet bowl 21 (refer to FIG. 4). The extension portion 113 has a hollow structure and is provided with an air intake opening 113a. Exemplarily, when a basic horizontal geometric plane is tangent to the top edge of the toilet bowl 21, the air intake opening 113a of the extension portion 113 can be entirely below this geometric plane or partially below this geometric plane. The mounting portion 111 has a hollow structure and is internally provided with a ventilation channel 111a that communicates with the air intake opening 113a to allow airflow. The air intake mechanism 13 includes a fan assembly 131 that communicates with both the ventilation channel 111a and the air intake opening 113a. The ventilation and drainage assembly 15 is arranged between the toilet waste outlet 21b and the sewage channel 30a and communicates with the fan assembly 131. This allows air to flow between the ventilation and drainage assembly 15 and the fan assembly 131. The fan assembly 131 may include a motor and an impeller linked to the motor's output shaft, which can guide the airflow when in operation. The fan assembly 131 is configured to draw air through the air intake opening 113a and direct the air from the ventilation and drainage assembly 15 into the sewage channel 30a, thus discharging the odors from the toilet bowl 21 into the sewage channel 30a, preventing the odors from spreading into the restroom.

[0035]Referring to FIGS. 1 and 2, in some embodiments, the air intake component 11 is plate-shaped and hollow. The mounting portion 111 is used to assemble the air intake component 11 to the top edge of the toilet bowl 21, facilitating the assembly and fixing of the air intake component 11 to the toilet 20. The extension portion 113 and the mounting portion 111 can be integrally molded to improve the forming efficiency of the air intake component 11. In other embodiments, the extension portion 113 can be fixed to the mounting portion 111, for example, by threaded connection or snap connection, allowing for a detachable connection between the extension portion 113 and the mounting portion 111, enabling the user to remove the extension portion 113 for cleaning or replacement.

[0036]The mounting portion 111 may have assembly holes 111b, which are used to fix the air intake component 11 and are adapted to the mounting holes 21c of the toilet seat. The assembly holes 111b may have a relatively large diameter to accommodate toilet seats of different sizes. For example, in the embodiment shown in FIG. 1, two assembly holes 111b are arranged at intervals along the length direction of the mounting portion 111. These two assembly holes 111b are in one-to-one correspondence with the mounting holes 21c on the toilet bowl 21, allowing for convenient assembly of the air intake component 11 with the toilet bowl 21 and the toilet seat.

[0037]Further, the air intake component 11 may include an adjustment plate 115 connected to the mounting portion 111. The adjustment plate 115 is movably provided within the assembly hole 111b. In some embodiments, the assembly hole 111b may be round, rectangular, or elliptical, etc., to accommodate toilet seat mounting holes 21c with different spacings and positions, improving the versatility of the air intake component 11. The adjustment plate 115 matches the assembly hole 111b and has a mounting slot 115a with a length greater than the diameter of the toilet seat mounting hole 21c. After the adjustment plate 115 is installed in the assembly hole 111b, it can rotate relative to the mounting portion 111 within the assembly hole 111b, changing the relative position of the mounting slot 115a to align with the toilet seat mounting hole 21c. This allows the toilet seat to be securely fixed to the toilet bowl 21 using fasteners such as bolts.

[0038]Additionally, in some embodiments, after the adjustment plate 115 is installed in the assembly hole 111b, its upper surface may not protrude beyond the upper surface of the mounting portion 111. For example, the upper surface of the adjustment plate 115 may be flush with the upper surface of the mounting portion 111 or may be recessed relative to the upper surface of the mounting portion 111, improving the structural compactness of the air intake component 11 and preventing excessive thickness that could increase the height of the toilet seat relative to the top edge of the toilet bowl 21, thus affecting user comfort.

[0039]In other embodiments, the air intake component 11 may undergo further modifications. For example, as shown in FIG. 3 or FIG. 4, a specially designed toilet seat 23 may replace the air intake component 11 shown in FIGS. 1 and 2. In this case, the air intake component 11 and the toilet seat 23 may be integrated into a single unit, reducing the number of components and improving the compactness of the structure. These modifications should be considered as equivalent alternatives to the air intake component 11 described in this application and should not be excluded from the scope of protection of this application. These alternatives will not be listed individually.

[0040]The toilet deodorizing device 10, including the air intake component 11, the air intake mechanism 13, and the ventilation and drainage assembly 15, is as described above. The air intake component 11 includes a mounting portion 111 and an extension portion 113 connected to the mounting portion 111. The mounting portion 111 is arranged at a top edge of a toilet bowl 21, and the extension portion 113 extends into the toilet bowl 21. The extension portion 113 has a hollow structure and an air intake opening 113a. The mounting portion 111 has a hollow structure and an internal ventilation channel 111a that communicates with the air intake opening 113a to allow airflow. The air intake mechanism 13 includes a fan assembly 131 that communicates with both the ventilation channel 111a and the air intake opening 113a. The ventilation and drainage assembly 15 is arranged between the toilet waste outlet 21b and the sewage channel 30a and communicates with the fan assembly 131. The fan assembly 131 draws air through the air intake opening 113a and directs it from the ventilation and drainage assembly 15 into the sewage channel 30a, discharging the odors from the toilet bowl 21 into the sewage channel 30a and preventing the odors from spreading into the restroom.

[0041]Due to the mounting part 111 being installed at a top edge of a toilet bowl 21, as an independent accessory for the toilet 20, users do not need to purchase a special toilet 20 or perform destructive modifications to the existing toilet 20. They can conveniently install the air intake component 11 onto the existing toilet 20, modifying the existing toilet 20, thereby enhancing convenience and reducing the cost of deodorization modification for the toilet 20. The design of the extension portion 113 extending into the toilet bowl 21 allows the fan assembly 131 to more easily extract air with a higher concentration of odor molecules from the toilet bowl 21a, thus more quickly discharging the more odorous air from the toilet bowl 21a into the wastewater channel 30a, improving deodorization efficiency and reducing the overall energy consumption of the toilet deodorizing device 10.

[0042]Continuing with reference to FIG. 2, the air intake mechanism 13 includes a housing 133 that is fixed relative to the position of the toilet bowl 21. The fan assembly 131 is located within the housing 133, and the housing 133 provides rigid support for the fan assembly 131 and protects it. The housing 133 has an intake opening 133a and an exhaust port 133b. The intake opening 133a communicates with the air intake component 11 and the air intake opening 113a, and the exhaust port communicates with the ventilation and drainage component 15. In this embodiment, the mounting part 111 of the air intake component 11 may protrude from the side of the toilet bowl 21, and the housing 133 is fixedly connected to the part of the air intake component 11 that protrudes from the side of the toilet bowl 21, improving the assembly convenience of the air intake component 11 and the housing 133.

[0043]In other embodiments, the housing 133 and the air intake component 11 can together form part or all of the toilet seat ring. In other words, in this embodiment, the air intake component 11 and the fan assembly 131 of the air intake mechanism 13 are integrated into the toilet seat ring 23. The toilet seat ring 23 can have all the functions of the air intake component 11 while also providing rigid support for the fan assembly 131 and protecting it. Configuring the intake opening 133a and exhaust port 133b on the toilet seat ring is also relatively easier, thus simplifying the structure of the toilet deodorizing device 10, reducing the number of components, and improving the compactness of the toilet deodorizing device 10.

[0044]The ventilation and drainage component 15 can have various structural forms. Referring to FIG. 2, in the first embodiment, the ventilation and drainage component 15 includes an exhaust flange 151, which is positioned between the toilet waste outlet 21b and the wastewater channel 30a, and is fixed relative to the position of the toilet waste outlet 21b, which is used for discharging wastewater from the toilet 20. The exhaust flange 151 has interconnected side interface 151a and exhaust port 151b. The exhaust port 151b can be located at the bottom or inner side of the exhaust flange 151 and communicates with the wastewater channel 30a, while the side interface 151a communicates with the fan assembly 131.

[0045]With reference to FIGS. 6 and 7, the ventilation and drainage component 15 may also include a hollow bolt 153. The hollow bolt 153 includes a hollow body 1531 and a connecting part 1533 that protrudes from the side of the hollow body 1531 and communicates with the hollow body 1531. The toilet 20's installation base may have at least one toilet installation hole 21d. The hollow body 1531 is passed through the toilet installation hole 21d and communicates with the fan assembly 131. The connecting part 1533 matches the side interface 151a of the exhaust flange 151 and connects to the side interface 151a, thus allowing the connecting part 1533 to communicate with the wastewater channel 30a. During the operation of the toilet deodorizing device 10, the fan assembly 131 draws air from the toilet bowl 21a through the air intake opening 113a. The air flows sequentially through the extension portion 113, the mounting part 111, the fan assembly 131, the hollow body 1531, the connecting part 1533, the exhaust flange 151, and the wastewater channel 30a, thereby discharging the odors from the toilet bowl 21 into the wastewater channel 30a and preventing the odors from spreading into the restroom.

[0046]The hollow body 1531 of the hollow bolt 153 can have external threads, which are used to adapt to external nuts, washers, and other accessories to securely fix the hollow bolt 153 in the toilet installation hole 21d. The end 1534 of the hollow bolt 153 opposite the hollow body 1531 can be installed in the toilet 20's toilet flange, thus reinforcing the toilet 20's fixation on the ground or floor.

[0047]As is well known, in some regions, a closet flange 31 may be provided between the toilet waste outlet 21b and the wastewater channel 30a. The closet flange 31 is fixedly connected to the wastewater channel 30a and secured to the installation floor. Additionally, the toilet 20 is also securely connected to the closet flange 31 via toilet installation bolts and nuts, providing the final effect of fixing the toilet 20 to the installation floor. In this case, the exhaust flange 151 can be placed on top of the closet flange 31, between the toilet waste outlet 21b and the closet flange 31. A sealing ring can be provided between the exhaust flange 151 and the closet flange 31 for sealing, and the exhaust flange 151 and the closet flange 31 can be connected via the end part 1534 of the hollow bolt 153. Of course, in some embodiments, the closet flange 31 can be omitted, and the exhaust flange 151 can be directly positioned corresponding to the toilet waste outlet 21b and the wastewater channel 30a.

[0048]Referring to FIG. 8, the hollow bolt 153 can be omitted. In the second embodiment, the ventilation and drainage component 15 may also include a fixed or deformable hollow connecting pipe 154. In the absence of a toilet installation hole 21d in the installation base of the toilet bowl 21, one end of the connecting pipe 154 is connected to the fan assembly 131, and the other end of the connecting pipe 154 can communicate with the side interface 151a, thus allowing the connecting pipe 154 to communicate with the wastewater channel 30a via the exhaust flange 15. In this embodiment, part or all of the connecting pipe 154 can be assembled and fixed to the side interface 151a of the exhaust flange 151, such as by insertion or snap-fit fixation. The connecting pipe 154 can also be integrally connected to the exhaust flange 151, such as by gluing or welding part of the connecting pipe 154 to the exhaust flange 151, or directly injection-molding the connecting pipe 154 and exhaust flange 151 as an integrated part. During the operation of the toilet deodorizing device 10, the fan assembly 131 draws air from the toilet bowl 21a through the air intake opening 113a. The air flows sequentially through the extension portion 113, the mounting part 111, the fan assembly 131, the connecting pipe 154, the exhaust flange 151, and the wastewater channel 30a, thereby discharging the odors from the toilet bowl 21 into the wastewater channel 30a and preventing the odors from spreading into the restroom. In general, the connecting pipe 154 can extend through an opening at the rear of the toilet 20 and connect to the side interface 151a of the exhaust flange 151 via an open channel. It is understood that some toilets 20 may not have a suitable opening or channel to accommodate the extension of the connecting pipe 154. In such cases, it is necessary to manually create a suitable channel at the rear or bottom of the toilet 20 for the connecting pipe 154 to extend and connect to the side interface 151a of the exhaust flange 151, including but not limited to drilling, enlarging holes, cutting, or grinding.

[0049]Referring to FIG. 9, in the third embodiment, the ventilation and drainage component 15 includes a drainage pipe 1551 extending along the first direction and a branch pipe 1553 protruding from an outer wall of the drainage pipe 1551 and extending along the second direction. The drainage pipe 1551 communicates with the toilet waste outlet 21b and the wastewater channel 30a for wastewater discharge, while the branch pipe 1553 communicates with the fan assembly 131 for gas flow. The first direction and second direction are arranged at an angle to each other. For example, the first direction and second direction may be perpendicular or form an acute angle, so that the branch pipe 1553 maintains a vertical or upward slanted position during use, providing a relatively large operational space for assembling the branch pipe 1553 with the exhaust pipe, improving the convenience of assembly, and minimizing the backflow of wastewater from the wastewater channel 30a into the branch pipe 1553. During the operation of the toilet deodorizing device 10, the fan assembly 131 draws air from the toilet bowl 21a through the air intake opening 113a. The air flows sequentially through the extension portion 113, the mounting part 111, the fan assembly 131, the branch pipe 1553, the drainage pipe 1551, and the wastewater channel 30a, thereby discharging the odors from the toilet bowl 21 into the wastewater channel 30a and preventing the odors from spreading into the restroom. Typically, when the toilet waste outlet 21b faces the rear of the toilet and the corresponding wastewater channel 30a is positioned on the rear wall, this drainage pipe 1551 configuration is used.

[0050]Referring to FIG. 10, in the fourth embodiment, the ventilation and drainage component 15 includes a first pipe section 1561 extending along the first direction, a second pipe section 1563 extending along the second direction, and a third pipe section 1565 connecting the first pipe section 1561 and the second pipe section 1563. The first direction and second direction are arranged at an angle to each other, for example, the first direction and second direction are perpendicular, and the third pipe section 1565 is outwardly curved. A branch pipe 1553, which communicates with the fan assembly 131, is protruded from a convex surface of the third pipe section 1565. The first pipe section 1561, second pipe section 1563, and third pipe section 1565 are interconnected and communicate with the toilet waste outlet 21b and the wastewater channel 30a for wastewater discharge, while the branch pipe 1553 communicates with the fan assembly 131 for gas flow. In this embodiment, the branch pipe 1553 maintains a vertical or upward slanted position relative to the ground during use, providing a relatively large operational space for assembling the branch pipe 1553 with the exhaust pipe, improving the convenience of assembly, and minimizing the backflow of wastewater from the wastewater channel 30a into the branch pipe 1553. During the operation of the toilet deodorizing device 10, the fan assembly 131 draws air from the toilet bowl 21a through the air intake opening 113a. The air flows sequentially through the extension portion 113, the mounting part 111, the fan assembly 131, the branch pipe 1553, the third pipe section 1565, and the wastewater channel 30a, thereby discharging the odors from the toilet bowl 21 into the wastewater channel 30a and preventing the odors from spreading into the restroom. Typically, when the toilet waste outlet 21b faces the rear of the toilet and the corresponding wastewater channel 30a is positioned on the floor, this drainage configuration is used.

[0051]Referring to FIG. 11, in the fifth embodiment, the ventilation and drainage component 15 includes a first connecting pipe 1571, a second connecting pipe 1573, and a flexible corrugated pipe 1575 connecting the first connecting pipe 1571 and the second connecting pipe 1573. The first connecting pipe 1571 has a branch pipe 1553 communicating with the fan assembly 131. The first connecting pipe 1571, the second connecting pipe 1573, and the corrugated pipe 1575 all communicate with the toilet waste outlet 21b and the wastewater channel 30a for wastewater discharge, while the branch pipe 1553 communicates with the fan assembly 131 for gas flow. In this embodiment, the branch pipe 1553 maintains a vertical or upward slanted position relative to the ground during use, providing a relatively large operational space for assembling the branch pipe 1553 with the exhaust pipe, improving the convenience of assembly, and minimizing the backflow of wastewater from the wastewater channel 30a into the branch pipe 1553. During the operation of the toilet deodorizing device 10, the fan assembly 131 draws air from the toilet bowl 21a through the air intake opening 113a. The air flows sequentially through the extension portion 113, the mounting part 111, the fan assembly 131, the branch pipe 1553, the first connecting pipe 1571, the corrugated pipe 1575, the second connecting pipe 1573, and the wastewater channel 30a, or flows sequentially through the extension portion 113, the mounting part 111, the fan assembly 131, the branch pipe 1553, the first connecting pipe 1571, and the wastewater channel 30a, thereby discharging the odors from the toilet bowl 21 into the wastewater channel 30a and preventing the odors from spreading into the restroom. Typically, when the toilet waste outlet 21b faces the rear of the toilet and the corresponding wastewater channel 30a is positioned on the floor or wall, this drainage configuration is used.

[0052]With reference to FIGS. 12, 13, 14, 15, and 16, in the sixth embodiment, the ventilation and drainage assembly 15 is constructed as part or all of the toilet rough-in kit. The toilet rough-in kit includes a mounting cover plate 1581 and a connecting pipe 1583 that connects the mounting cover plate 1581 and the toilet waste outlet 21b. The mounting cover plate 1581 is used to fix the toilet rough-in kit to the ground or other supporting surface, for example, by using bolts to fix the toilet rough-in kit to the ground or other supporting surface. The mounting cover plate 1581 has a first channel 1581a, and the connecting pipe 1583 has a second channel 1583a. The second channel 1583a may include a vertical section, a curved section, and a horizontal section. One of the connecting pipe 1583 and the mounting cover plate 1581 is provided with a branch pipe 1553 that communicates with the fan assembly 131. Both the first channel 1581a and the second channel 1583a are connected to the sewage channel 30a for sewage discharge, and the branch pipe 1553 communicates with the fan assembly 131 for gas flow. During the operation of the toilet deodorizing device 10, the fan assembly 131 sucks in air from the toilet bowl 21a through the intake opening 113a. The air flows sequentially through the extension portion 113, the mounting portion 111, the fan assembly 131, the branch pipe 1553, the first channel 1581a, and the sewage channel 30a, thus discharging the odor from the toilet bowl 21 into the sewage channel 30a and preventing the odor from spreading into the restroom. Typically, when the sewage channel 30a is provided on the ground and the toilet rough-in kit is used, this drainage method will be adopted.

[0053]In this embodiment, the branch pipe 1553 can be protruded from the highest point of the mounting cover plate 1581, away from the installation ground of the toilet 20, and perpendicular to the installation ground of the toilet 20, as shown in FIGS. 12, 13, and 14. The branch pipe 1553 remains in a vertical upward position relative to the ground during use, providing a relatively large operating space for the assembly of the branch pipe 1553 and the exhaust pipe, improving the convenience of assembling the exhaust pipe and branch pipe 1553, and minimizing the backflow of sewage from the sewage channel 30a into the branch pipe 1553. Of course, the branch pipe 1553 can also be protruded from the vertical section of the connecting pipe 1583 and provided at an angle to the installation ground of the toilet 20, as shown in FIG. 15. For example, the axis of the branch pipe 1553 extends obliquely upward relative to the vertical section of the connecting pipe 1583, forming an acute angle. The branch pipe 1553 remains in an oblique upward position relative to the ground during use, providing a relatively large operating space for the assembly of the branch pipe 1553 and the exhaust pipe, improving the convenience of assembling the exhaust pipe and branch pipe 1553, and minimizing the backflow of sewage from the sewage channel 30a into the branch pipe 1553.

The Second Embodiment

[0054]The second embodiment of the present application discloses a toilet deodorizing device 10 applied to a water closet carrier system, which includes an air intake component 11, an air intake mechanism 13, and a ventilation component 15′. The air intake component 11 includes a mounting portion 111 and an extension portion 113 connected to the mounting portion 111. The mounting portion 111 is arranged at a top edge of a toilet bowl 21, and part or all of the extension portion 113 extends into the toilet bowl 21, including extending into the downward concave part of the toilet bowl 21a (FIGS. 1, 3), or extending into the central part of the upper opening 21a1 of the toilet bowl 21 (FIG. 4). The extension portion 113 has a hollow structure and has an intake opening 113a. Exemplarily, when a basic horizontal geometric plane is tangent to the top edge of the toilet bowl 21, the intake opening 113a of the extension portion 113 can be entirely below this geometric plane, or partially below this geometric plane. The mounting portion 111 has a hollow structure and is internally provided with a ventilation channel 111a that communicates with the intake opening 113a for air flow. The air intake mechanism 13 includes a fan assembly 131 that is connected to the ventilation channel 111a and the intake opening 113a. The fan assembly 131 may include a motor and a fan wheel linked to the motor's output shaft, which can guide airflow during operation. The fan assembly 131 can suck in air through the intake opening 113a and guide the air from the ventilation component 15′directly into the exhaust duct 20e of the toilet carrier 20 (FIG. 17), thereby discharging the odor from the toilet bowl 21 into the exhaust duct 20e and preventing the odor from spreading into the restroom.

[0055]Unlike the first embodiment, the ventilation component 15′'of the second embodiment is connected to the exhaust duct 20e of the toilet carrier 25 of the water closet carrier system. The toilet carrier 25 is generally fixed to the ground, and the corresponding toilet 20 is generally fixed to the toilet carrier 25 in a wall-mounted manner. The exhaust duct 20e of the toilet carrier 25 is correspondingly arranged above the drainage pipe 20f behind the wall where the toilet 20 is installed. The ventilation component 15′may include a fixed or deformable hollow connecting pipe 154 and a ventilation part 156. The connecting pipe 154 is connected to the air intake mechanism 13, and the ventilation part 156 is connected to the exhaust duct 20e. The ventilation part 156 may adopt a T-joint or side connection pipe structure, and it can be connected to the exhaust duct 20e using flexible or rigid connections, enabling the fan assembly 131 to suck in air through the intake opening 113a and direct the air from the ventilation component 15′ into the exhaust duct 20e. In this embodiment, the air does not need to pass through the sewage pipe, reducing mutual interference, and allowing the odor to be expelled more quickly and easily. Other structures and working principles of the toilet deodorizing device 10 can refer to the first embodiment of this application, which will not be repeated here.

[0056]Although the present disclosure has been described and illustrated with preferred embodiments and several alternatives, it is not limited to the specific descriptions contained in this specification. Other alternative or equivalent components may also be used to practice the present disclosure.
