CROSS-REFERENCE TO RELATED APPLICATIONS

[0001]The application claims priority to Chinese patent application No. 2025200395940, filed on Jan. 8, 2025, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

[0002]The present disclosure relates to the technical field of bubble machines, in particular to an electric bubble box structure for generating big bubbles.

BACKGROUND

[0003]A bubble machine is a machine configured to generate bubbles and is a toy for children. In traditional bubble blowing games, a tool with a ring is generally used to dip liquid soap, the liquid soap will form a layer of film on the ring, and then air is blown onto the ring, to form a bubble or a series of bubbles. When light passes through the film of soap bubbles, the top and bottom of the film will be refracted, then the bubbles reflect different colors, therefore, the bubble blowing game is favored by many children. However, since manual blowing requires physical effort, and younger children cannot master skills of blowing, then many bubble machine toys capable of automatic blowing emerge.

[0004]For traditional bubble machine toys, a bubble liquid is coated on a ring through a sweeping rod which swings up and down. During an operating process, the bubble liquid may burst before covering the entire ring, therefore, bubbles cannot be formed rapidly and continuously, and the number of bubbles is small. Moreover, although many bubbles may be blown out automatically and continuously by using a bubble machine toy, however, the bubble machine toys generally used now can only blow out strings of small bubbles with single functions and low playability. While the existing bubble machine toys which can generate big bubbles are generally complex in structure and are inconvenient for children to use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030]Embodiments of the present disclosure are described in detail below, examples of embodiments are shown in the accompanying drawings, and the embodiments described below by reference to the accompanying drawings are exemplary and intended to be used to explain the present disclosure, rather than being construed as a limitation of the present disclosure.

[0031]As shown in FIG. 1, an objective of the present disclosure is to provide an electric bubble box structure for generating big bubbles, solving the problems of complex structure and low playability of large bubble machines.

[0032]In order to achieve the above objective, the present disclosure provides an electric bubble box structure for generating big bubbles. The electric bubble box structure includes a housing 1, a power structure 2, a bubble outlet structure 3 and a three-way valve 4, where the power structure 2 is fixedly connected to the housing 1, the power structure 2 is configured to provide power, and the housing 1 is provided with a bubble outlet 10, the bubble outlet structure 3 includes a fan 30, a trigger 31, and a bubble outlet ring 32, wherein the fan 30 is fixed in the housing 1 and is connected to the power structure 2, the fan 30 faces towards the bubble outlet 10, the bubble outlet ring 32 is oppositely arranged and is located in the housing 1, the bubble outlet ring 32 is rotationally connected to the housing 1, the bubble outlet ring 32 is arranged between the fan 30 and the bubble outlet 10, one end of the trigger 31 passes through the housing 1 and the other end is connected to the housing 1, one end of the trigger 31 extending into the housing 1 is connected to the bubble outlet ring 32 and is configured to drive the bubble outlet ring 32 to rotate, the three-way valve 4 is fixedly connected to the housing 1, an inlet of the three-way valve 4 is connected to the power structure 2 and is configured to extract bubble liquid, and an outlet of the three-way valve 4 is connected to the bubble outlet ring 32 and is configured to deliver the bubble liquid to the bubble outlet ring 32. In the present disclosure, through a bubble outlet ring 32 and an air blower in a bubble outlet structure 3, big bubbles can be blown out continuously. Specifically, the housing 1 is connected to a bubble liquid bottle (not shown in the figures), and the bubble liquid is extracted by the power structure 2 and then output to the bubble outlet ring 32 to form a bubble film, and then the bubbles are blown out by the fan 30. As to this structure, bubble liquid can be extracted and bubbles can be blown out simultaneously through a power structure 2 to optimize the structure of the box 20, each part is compact in structure, occupies a small space, and can effectively reduce production cost; meanwhile, the bubbles can be blown out through the trigger 31, and the bubble output ring 32 is conducive to making the bubble liquid uniform on a ring surface, thereby further forming bigger and more stable bubbles. Two outlets of the three-way valve 4 are directly connected to the bubble outlet ring 32, thereby being conducive to ensuring delivery of the bubble liquid and making a bubble generation process smoother.

[0033]As shown in FIG. 2, the housing 1 is internally provided with a fixed rotary groove 11, the bubble outlet ring 32 includes a ring channel 321, a rotating shaft 322, and a pull rod 323, where the rotating shaft 322 is arranged at upper and lower ends of the ring channel 321, one end of the pull rod 323 is connected to the rotating shaft 322, the rotating shaft 322 is rotationally connected to the fixed rotary groove 11, one end of the trigger 31 extending into the housing 1 is provided with a groove pull opening 311, and the other end of the pull rod 323 is inserted into the groove pull opening 311. In this structure, since the rotating shaft 322 is arranged in the fixed rotary groove 11 and the rotating shaft 322 is fixedly connected to the ring channel 321, then the ring channel 321 is limited and can only rotate. When the trigger 31 is pulled, the trigger 31 will drive the pull rod 323 of the bubble outlet ring 32 to move, and then the two bubble outlet rings 32 are unfolded and separated. When the two bubble outlet rings 32 are unfolded and separated, the bubble liquid is stretched to form a film-like bubble film, and the bubble film is blown by the fan 30 to form big bubbles, thereby effectively laying a foundation for the fan 30 to blow bubbles and ensuring stable formation of bubble films. The start of the power structure 2 is linked to the trigger 31, and when the trigger 31 is pulled, bubble liquid can be extracted and the fan 30 is driven synchronously to blow bubbles continuously. The rotating shaft 322 is fixed in the rotary groove and is closely connected to the bubble outlet ring 32, thereby ensuring precise motion control of the bubble outlet ring 32 in a specific direction, making delivery of power from the trigger 31 to the bubble outlet ring 32 direct and efficient, and maintaining the stability and action precision of the entire bubble generating process.

[0034]As shown in FIG. 3, a plurality of retention grooves 3211 are formed in opposite sides of the ring channel 321. The bubble outlet ring 32 is designed symmetrically, the retention grooves 3211 are formed in opposite sides of the ring channel 321, and these grooves are recessed towards the other side of the ring channel 321 to form a local low-pressure region. Through such a design, the bubble liquid is easily gathered at the grooves, and no sweeping rod in traditional structures is required to coat the bubble liquid, thereby reducing the number of parts and optimizing the structure of the apparatus. The retention grooves 3211 help to form a more uniform and stable bubble liquid layer on the ring channel 321.

[0035]In addition, referring to FIG. 2, the bubble outlet structure 3 further includes an air g guide frame 33, the air guide frame 33 is located between the fan 30 and the bubble outlet ring 32, and the air guide frame 33 is surrounded with a plurality of air inducing blades 331 and faces towards the bubble outlet ring 32. The plurality of air inducing blades 331 on the air guide frame 33 face towards the bubble outlet ring 32, and are capable of arranging the dispersed wind beams blown out from the fan 30 to be more orderly and concentrated, then a wind field conducive to the formation of bubbles is created, thereby not only ensuring uniform distribution of wind force, but also preventing the bubble film from being subjected to a force which is too large or too small due to local non-uniform wind force through the guiding and adjusting effects of the air inducing blades 331. The uniform distribution of wind force helps the bubble film to be more stable when the bubble film is transformed into the bubbles, thereby reducing the risk of bursting of the bubbles at the initial stage of bubble formation.

[0036]As shown in FIG. 4, the housing 1 is provided with a first pull hook 12, the trigger 31 is provided with a second pull hook 312, and the first pull hook 12 and the second pull hook 312 are connected through an elastic member, such that the trigger 31 can be automatically reset after being pulled, thereby improving the convenience of operation, reducing operating steps of users, and enabling users to continuously generating the bubbles more rapidly.

[0037]As shown in FIG. 5, the power structure 2 includes a box 20, a dual output motor 21, a transmission gear 22, a peristaltic gear 23, and a flow hose 24, where the box 20 is connected to the housing 1, one end of the dual output motor 21 is connected to the fan 30, and the other end is provided with a worm and is engaged with the transmission gear 22, the peristaltic gear 23 is engaged with the transmission gear 22, and the peristaltic gear 23 is provided with a peristaltic column 231. The peristaltic column 231 squeezes the flow hose 24, one end of the flow hose 24 is connected to an inlet of the three-way valve 4, and the other end is inserted into the bubble liquid. In this power structure 2, a single motor is adopted to drive multiple functional components, thereby effectively utilizing the power source and meanwhile solving the problem of space occupation that may be caused by multiple motors. Through a design of the dual output motor 21, two steps of the fan 30 blowing air and the flow hose 24 delivering bubble liquid are combined, thereby ensuring synergistic operation of the air force and supply of bubble liquid in the process of bubble generation, and helping to generate stable and high-quality bubbles. The peristaltic column 231 on the peristaltic gear 23 steadily pushes the flow of the bubble liquid by squeezing the flow hose 24, and this squeezing manner also prevents air bubbles from mixing into the bubble liquid and improves purity of the bubble liquid, thereby producing more uniform and beautiful bubbles. In addition, through connection between the box 20 and the housing 1, various components of the power structure 2 are integrated into a compact entirety, thereby effectively reducing the overall size of the bubble outlet apparatus.

[0038]As shown in FIG. 6, the bubble outlet structure 3 further includes an adjusting mechanism 34, where the adjusting mechanism 34 includes an adjusting member 341, an oblique push block 342, an elastic member 343, a restriction stopper 344, an oblique sleeve 345 and a lock nut 346, and the housing 1 is internally provided with a cavity 13 and a correction tube 14 connected to the cavity 13, the oblique push block 342 is located in the cavity 13 and slides in the cavity 13, both ends of the elastic member 343 abut against one side of the oblique push block 342 and the cavity 13, respectively, one end of the adjusting member 341 passes through the housing 1 and the correction tube 14 and is engaged with the housing 1, the lock nut 346 is engaged with the adjusting member 341 and abuts against the housing 1, and one end of the adjusting member 341 extending into the cavity 13 is connected to the oblique sleeve 345, and the oblique sleeve 345 abuts against the other side of the oblique push block 342, one side, abutting against the oblique sleeve 345, of the oblique push block 342 is an oblique surface, and the oblique push block 342 drives the restriction stopper 344 to move, the bubble outlet ring 32 is provided with a convex column 324, and the restriction stopper 344 is located within a movement range of the convex column 324. The unfolding angle of the bubble film has a significant effect on the stability and flight distance of bubbles: a smaller angle is beneficial for uniform distribution of the air pressure inside bubbles, so as to improve the stability of bubbles; while a larger unfolding angle helps to optimize the shape and aerodynamic properties of the bubbles, enabling the bubbles to fly further.

[0039]The principle is as follows: when an unfolding angle is increased, the tension distribution of the bubble film changes accordingly, the tension at the bottom is enhanced, thereby resulting in a tighter contraction at the bottom of bubbles, the materials are more concentrated, and the overall shape is more streamlined. This helps the air to flow smoothly over the bubble surface, reduces the turbulence of the air flow, lowers the resistance, and makes the bubbles fly further. On the contrary, a smaller unfolding angle will shorten the bubble generation period, and more bubbles can be generated per unit time; at the same time, a smaller angle allows for more uniform distribution of air pressure inside the bubbles, thereby reducing the possibility of bursting, making it less susceptible to external interference in flight, and making its flight path easier to predict.

[0040]Specifically, the oblique sleeve 345 is in contact with the oblique push block 342, and both sides of the oblique push block 342 bear an acting force of the elastic member 343 and the adjusting member 341, respectively. By designing an oblique surface on the oblique push block 342, linear movement of the adjusting member 341 can be cleverly converted into precise displacement control of the restriction stopper 344, such that the position of the convex column 324 on the bubble outlet ring 32 can be accurately adjusted, and an unfolding angle of a bubble film forming structure can be further adjusted. The restriction stopper 344 is located on a moving trajectory of the convex column 324, and movement of the inclined push block 342 directly limits the convex column 324, thereby ensuring precise and stable adjustment of the unfolding angle of the bubble film forming structure. Therefore, when this adjusting mechanism 34 is utilized, the angle between the two bubble outlet rings 32 can be adjusted according to the stability of bubbles and the desired flight distance, thereby enhancing the interactivity and fun of toys.

[0041]Wherein the angle of the two inclined surfaces is 45°, the adjusting member 341 may be a bolt, a hand wheel and the like.

[0042]Further, the adjusting member 341 can be locked by the lock nut 346, thereby preventing displacement of the adjusting member 341 during a bubble blowing process, and affecting the unfolding angle of the bubble outlet ring 32. The correction tube 14 can correct the adjusting member 341 to ensure that the adjusting member 341 can rotate smoothly during an adjustment process and ensure stable operation of the mechanism.

[0043]The above disclosure is merely one or more of the better embodiments of the present application, and cannot be used to limit the scope of the present application, those skilled in the art can understand all or part of the flows of the above embodiments, moreover, equivalent changes made according to the claims of the present application still fall within the scope of the present application.
