Description

Technical Field

[0001] This utility model relates to the field of children's toys, and in particular to a toy bubble box. Background Technology

[0002] Bubble toys are popular in children's entertainment and outdoor interactive scenarios because of their dreamy visual effects and interactive fun. Compared with traditional manual bubble blowing tools, electric bubble machines can continuously and automatically output bubbles by using a motor to drive the air to blow the bubble liquid film, which significantly enhances the fun and interactive experience of the game.

[0003] However, existing electric bubble machines still face several technical bottlenecks in practical use: First, the conventional fan blade structure design is relatively simple, and the blade shape is not optimized, resulting in low air output efficiency and high wind resistance. This not only leads to high power consumption but also limits the air output, directly affecting the amount and continuity of bubble generation. Second, the liquid outlet in the liquid supply system is mostly connected to the surrounding structure through a solid rib. This design can easily hinder the flow of bubble liquid during operation, causing uneven liquid distribution, poor return of liquid, or even leakage, affecting the stability of bubble generation and leading to liquid waste. In addition, common bubble-generating discs are prone to splashing or accumulating bubble liquid when dipping at high speed. Especially when the liquid film is not completely blown away, residual liquid will drip down along the bubble ring, which not only contaminates the equipment but also results in low utilization of bubble liquid. Especially under low pressure or low power conditions, problems such as sticky bubbles, uneven bubble breakage, or leakage are likely to occur, affecting continuous bubble generation performance and user experience.

[0004] Therefore, how to develop a toy bubble box that can effectively reduce wind resistance and power consumption, avoid leakage and bubble solution waste, and improve the reliability of the whole machine and the utilization efficiency of bubble solution while ensuring uniform and continuous bubble output has become a technical problem that needs to be solved by people in this field.

[0010] Preferably, the liquid guiding structure includes a liquid guiding column, an anti-slip sleeve, and a liquid guiding tube.

[0015] Preferably, an insertion hole is provided at the center of the air guide plate, and an insertion post is fixedly connected to the inner side of the foaming plate, the insertion post being rotatably inserted into the insertion hole.

[0016] Preferably, the housing further includes an elastic clutch pressure plate, which is fixedly connected to the front mold structure of the housing.

[0018] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0019] 1) By designing the wind turbine blades as curved fan-shaped structures and specifically optimizing their installation angle and thickness, the installation angle at the center of the blades is controlled within the range of 25° to 35°, and the thickness is controlled within the range of 0.8mm to 1.5mm.

[0020] Within the range, the generated airflow is more concentrated and transported upward, significantly reducing the collision and friction between the airflow and the surrounding structures such as the outer shell and air guide plate, effectively reducing wind resistance and power loss, and achieving an increase in effective air volume without increasing the motor speed, which helps to reduce the overall power consumption and extend the battery life.

[0021] 2) The connection between the liquid outlet seat and the center of the second connecting strip, as well as the connection between the liquid outlet seat and the first annular frame, adopt a hollow structure design, which completely eliminates the traditional solid bone position, fundamentally eliminates the phenomenon of bubble liquid flow blockage or backflow caused by bone position obstruction, significantly improves the smoothness and uniformity of liquid distribution, effectively prevents leakage, and improves the continuity and reliability of bubble production.

[0022] 3) The water collection tank can collect residual bubble liquid that has not been completely blown off from the bubble ring in time through the scraper formed on its side wall, and temporarily store it in the water collection tank by means of liquid surface tension. When the accumulated liquid reaches a certain amount, it can be re-dipped by the bubble ring to form a new liquid film. This structure realizes the recycling of bubble liquid, significantly improves liquid utilization, reduces waste, and also helps to maintain bubble stability and alleviate leakage and sticking problems under low pressure conditions.

[0023] 4) The elastic clutch pressure plate and the outer shell front mold adopt an integrated molding structure, so that the friction parts are concentrated on the same injection parting surface, which helps to maintain the stability of the friction state and avoid functional abnormalities caused by misalignment of the parting surface. At the same time, this integrated design improves the consistency of part molding and assembly reliability, which helps to ensure the overall quality of the product and extend its service life.

[0024] 5) The peristaltic cover and the outer shell are integrally molded, which can effectively limit the liquid guide column of the transmission component and prevent it from shifting or falling off during the automated assembly process, thereby supporting fully automated assembly, reducing manual intervention costs, and improving production efficiency and product consistency.

[0025] 6) The water-locking layer structure set on the top of the liquid outlet seat realizes rapid flow and uniform distribution of bubble liquid through multiple water guide channels. With the help of the surface tension generated by the fine channels, it can effectively suppress liquid side leakage even when the equipment is tilted, further improving the stability of bubble production and the controllability of liquid use.

[0036] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0037] like Figure 1-8 As shown, a toy bubble box includes a shell 1, a dual-head motor 2, a transmission gear set 3, a fan blade 4, an air guide plate 5, a bubble-generating plate 6, and a liquid outlet 7. The shell 1 is composed of two split shells that fit together and form a cavity structure with an open top. The dual-head motor 2 is fitted and installed in the inner cavity of the shell 1 and is fixed by the fitting structure inside the shell 1. The fan blade 4 is fixedly connected to the rotating end at the top of the dual-head motor 2, and the blades of the fan blade 4 are axial flow blades with a curved fan-shaped structure. The installation angle of the middle part of the blade is 25° to 35°, and the blade thickness is 0.8mm to 1.5mm. The air guide plate 5... The disc 5 is snapped into the opening at the top of the outer casing 1 and located outside the fan blade 4. The bubble-generating disc 6 includes a first annular frame 61 and a bubble-generating assembly. The bubble-generating assembly is formed by multiple sets of first bubble-generating rings 64 connected as a whole by radial first connecting strips 62. The central connecting part of the first connecting strip 62 has an inward concave structure, and the first connecting strip 62 is fixedly connected to the first annular frame 61. The bubble-generating assembly is rotatably connected to the outside of the air guide disc 5. A toothed ring 63 is provided on the outer circumference of the first annular frame 61. The rotating end at the bottom of the dual-head motor 2 is connected to the toothed ring 63 through the transmission gear set 3.

[0038] The air guide plate 5 includes a second annular frame 51, a first air guide plate 52, and a second air guide plate 53. Multiple sets of first air guide plates 52 are evenly spaced inside the second annular frame 51. The liquid outlet seat 7 is fixedly connected between two adjacent first air guide plates 52 by a second connecting strip 54. The connection between the liquid outlet seat 7 and the center connection of the second connecting strip 54, as well as between the liquid outlet seat 7 and the first annular frame 61, are all provided with a hollow structure. Multiple second air guide plates 53 are spaced apart on the top of the first air guide plates 52. At least one second air guide plate 53 located away from the liquid outlet seat 7 in the direction of rotation of the fan blade 4 is provided with a water collection trough 55 on its top.

[0039] Specifically, in this embodiment, the installation angle of the middle part of the blade of the fan blade 4 is preferably 30°, and the thickness of the blade is preferably 1.2mm. By optimizing the installation angle of the fan blade, the airflow blown out by the fan blade 4 can be concentrated and transported upward, effectively avoiding the airflow from colliding with the inner wall of the outer shell 1, the air guide plate 5, or the bubble plate 6, thereby reducing wind resistance, reducing battery power consumption, and increasing the air volume without increasing the motor speed. In addition, by optimizing the thickness of the fan blade, the blade structure is made thinner, further reducing rotational wind resistance and motor load.

[0040] Specifically, in addition to the necessary limiting and fixed connection achieved by the second connecting strip 54, the liquid outlet 7 adopts a hollow structure between its central connection with the second connecting strip 54 and between it and the first annular frame 61. This design eliminates the rib position, thereby preventing the rib position from blocking the flow of bubble liquid during operation. At the same time, it effectively prevents the bubble liquid from flowing back and spreading along the rib position, thus structurally eliminating the phenomenon of leakage.

[0041] Specifically, by setting a second air guide plate 53, the bubbles that were originally easy to sink when blown out by a gentle breeze are changed to an intermittent and rapid bubble-blowing mode, which makes the blown bubbles break faster, more numerous, and lighter in texture, thereby extending the time the bubbles stay in the air. This greatly improves the efficiency of use with the same amount of bubble solution and saves more bubble solution.

[0042] Specifically, the central connecting part of the first connecting strip 62 has a concave structure. This deepened concave design can provide a larger accommodating space, preventing the bubble film from sticking to the membrane or causing bubbles and leakage due to liquid accumulation at low pressure, and further ensuring smooth and uniform bubble production.

[0043] Specifically, the transmission gear set 3 includes a double-toothed disc 31, a gear disc 32, a double-toothed block 33, and a double-headed gear rod 34. A worm gear 8 is fixedly installed on the rotating end of the bottom of the double-headed motor 2. The bottom of the double-toothed disc 31 is meshed with the worm gear 8. The other side of the double-toothed disc 31 is meshed with the gear disc 32. The top of the gear disc 32 is meshed with the double-toothed block 33. The other side of the double-toothed block 33 is meshed with the double-headed gear rod 34. The other end of the double-headed gear rod 34 is meshed with the gear ring 63. A fluid guiding structure 9 is fixedly connected to the outer side of the gear disc 32.

[0044] Specifically, the liquid guiding structure 9 includes a liquid guiding column 91, an anti-slip sleeve 92, and a liquid guiding tube. Two liquid guiding columns 91 are symmetrically installed on the outer side of the gear disk 32. The surface of the liquid guiding column 91 is fitted with an anti-slip sleeve 92, and the surface of the anti-slip sleeve 92 is used to fit and connect with the liquid guiding tube.

[0045] Specifically, the transmission gear set 3 and the fluid guiding structure 9 in this utility model are existing structures. The transmission gear set and fluid guiding structure in the reference patent (patent number: CN221601250U) will not be described in detail here.

[0046] Specifically, the peristaltic ratio of the liquid guide tube to the rotational speed ratio of the dual-head motor 2 is 1:54, and the rotational speed ratio of the foaming disc 6 to the rotational speed ratio of the dual-head motor 2 is 1:110.

[0047] Specifically, the top of the liquid outlet seat 7 is provided with a water-locking layer structure composed of multiple water guide grooves 71.

[0048] Specifically, the water-locking layer structure achieves liquid guiding function through the water-guiding grooves 71 on its surface, enabling the bubble liquid to be guided quickly and distributed more evenly, thereby further ensuring the stability of bubble production; at the same time, with the liquid surface tension effect generated by the small structure of the water-guiding grooves 71, the risk of liquid side leakage can be effectively reduced when the liquid outlet seat 7 is tilted.

[0049] Specifically, a conduit plug 72 is fixedly connected to one side of the liquid outlet seat 7, and the liquid outlet end of the liquid guide tube is connected to the conduit plug 72.

[0050] Specifically, the sidewall of the top opening of the water collection tank 55 forms a scraper, the height of which is higher than the height of the second air guide plate 53, and the top of the scraper is located 0.5mm below the first bubble ring 64.

[0051] Specifically, the water collection tank 55 is used to collect the bubble liquid remaining after the first bubble ring 64 breaks. The residual liquid adhering to the bottom of the first bubble ring 64 after the film breaks is scraped by the scraper and stored in the water collection tank 55. When the liquid in the water collection tank 55 reaches a certain amount, under the action of liquid surface tension, the liquid level can be slightly higher than the height of the scraper without overflowing. When the accumulated bubble liquid comes into contact with the first bubble ring 64 again, a new liquid film can be formed on its surface. Under the action of the airflow of the fan blade 4, new bubbles are generated, thereby improving the utilization rate of bubble liquid, stabilizing the bubble production performance, avoiding waste, and effectively alleviating the problems of leakage and bubble entanglement under low pressure conditions.

[0052] Specifically, the number of water collection tanks 55 can be flexibly set according to actual usage needs, and is not limited here.

[0053] Specifically, the introduction of the water collection tank 55 enhances the adaptability of this invention to the specifications of the bubble-generating disc 6, allowing more first bubble-generating rings 64 to be arranged within the first annular frame 61. This structure also supports the bubble-generating disc 6 to operate at a lower speed, which helps to reduce transmission resistance and wind resistance, lower the overall current, and achieve the effects of saving power and extending service life. At the same time, this design can avoid the waste problem caused by multiple first bubble-generating rings 64 being dipped in excessive bubble solution at one time, resulting in bubbles not being generated in time.

[0054] Specifically, the top of the scraper is located 0.5 mm below the first bubble ring 64. This gap design can both avoid interference with the rotation of the first bubble ring 64 and effectively collect the residual liquid after the membrane breaks.

[0055] Specifically, an insertion hole 56 is provided at the center of the air guide plate 5, and an insertion post 65 is fixedly connected to the inner side of the foaming plate 6. The insertion post 65 is rotatably inserted into the insertion hole 56.

[0056] Specifically, the outer shell 1 also includes an elastic clutch pressure plate 11, which is fixedly connected to the front mold structure of the outer shell 1. The bottom end of the elastic clutch pressure plate 11 is used to abut against the gear plate at the bottom of the double-headed gear rod 34, and the elastic clutch pressure plate 11 is integrally formed with the front mold shell of the outer shell 1.

[0057] Specifically, in this utility model, the elastic clutch pressure plate 11 and the front mold structure of the outer shell 1 are set as an integral molding structure. This design concentrates the friction points in the front mold area, which is conducive to the stable control of the friction state at the injection parting surface and avoids the impact on the function of the parts due to the instability of the parting surface friction. The integral molding structure ensures that the elastic clutch pressure plate 11 can normally realize the clutch function, while also improving the stability of injection molding production and the consistency of parts, thereby ensuring the reliability and durability of the overall product quality.

[0058] Specifically, a peristaltic cover 12 is also provided on the rear mold shell of the outer shell 1. The peristaltic cover 12 is integrally formed with the rear mold shell of the outer shell 1. The working end of the peristaltic cover 12 is sleeved on the central shaft of the gear disk 32, and the inner side of the peristaltic cover 12 is used to abut against the liquid guiding column 91.

[0059] Specifically, addressing the issue that the liquid guide tube needs to be manually installed into the gearbox at position 3 of the transmission gear set during assembly, and that the liquid guide column 91 is prone to falling off during automated production, this utility model innovatively designs a peristaltic cover 12. The peristaltic cover 12 can effectively limit the installation position of the liquid guide column 91, preventing it from shifting or falling off during the production process, thereby supporting the use of fully automated equipment for assembly. This not only reduces labor costs but also significantly improves production efficiency and product consistency.

[0060] Specifically, this utility model places the liquid outlet 7 on the side close to the transmission gear set 3, thereby shortening the length of the liquid guide tube, reducing material consumption, and lowering costs; at the same time, the shorter liquid guide tube can accelerate the delivery process of the bubble liquid, which is conducive to improving the bubble response speed and overall bubble efficiency.

[0061] The usage process of this utility model is as follows:

[0062] First, the user injects the bubble solution into the storage container connected to the liquid guide tube, and ensures that the liquid guide tube is securely connected to the tube plug on the liquid outlet. Then, the dual-head motor 2 is started. Its top rotating end drives the fan blade 4 to rotate, generating an upward concentrated airflow, while the bottom rotating end drives the transmission gear set 3 to rotate through the worm gear 8.

[0063] Secondly, the gear disk 32 in the transmission gear set 3 drives the outer liquid guide column 91 to rotate, and the continuous pumping of bubble liquid is achieved by squeezing the liquid guide tube. The pumped bubble liquid is transported to the water-locking layer structure on the top of the liquid outlet seat 7 through the conduit plug 72, and is evenly diffused through the water guide groove 71.

[0064] Secondly, the gear disk 32 transmits power to the gear ring 63 through the double tooth block 33 and the double-headed gear rod 34, thereby driving the entire bubble disk 6 to rotate slowly, so that the first bubble ring 64 sequentially dips into the bubble liquid evenly distributed on the liquid outlet seat 7 and forms a liquid film.

[0065] Then, the airflow generated by the fan blade 4 is guided and accelerated by the first air guide plate 52 and the second air guide plate 53 on the air guide plate 5, and blows towards the continuously rotating first bubble ring 64, blowing away the liquid film and forming continuous and uniform bubbles.

[0066] Finally, some of the residual liquid film that was not completely blown away drips down the bottom of the first bubble ring 64 and is scraped and collected by the scraper formed by the side wall of the water collection tank 55 and temporarily stored in the tank. The accumulated liquid is kept in the tank under the action of surface tension. After the liquid level rises, it can be dipped by the first bubble ring 64 to form a new liquid film, thereby realizing the recycling of bubble liquid and improving the efficiency of use. The whole process is continuous and stable, with a large amount of bubble output and low power consumption.
