Description

Technical Field

[0001] The utility model relates to the technical field of bubble machines, in particular to an anti-leakage structure for a toy bubble water bottle. Background Art

[0002] In the current market, the common anti-leakage bubble structures mainly have the following two types:

[0003] Firstly, a traditional duckbill one-way valve (made of soft rubber) is used and fixed below the bottle mouth. In the initial use stage, this structure shows good anti-leakage effect. However, as the use time goes by, the blowing tool needs to pass through the one-way valve repeatedly, which is very likely to cause the one-way valve to deform or even be damaged. Moreover, the soft rubber of the one-way valve will be in direct contact with the blowing tool. When the blowing tool is pulled out, the tongue of the one-way valve, which is the key sealing component, is easily affected by friction and changes from the original natural state to an inward-rolled shape, thus causing the anti-leakage function to fail.

[0004] Secondly, a long blowing tool guiding pipe is set at the bottle mouth, and the principle of communicating vessels is used to achieve anti-leakage. The principle is that as long as the liquid does not exceed the notch of the pipe when it is inverted, a certain anti-leakage effect can be achieved. However, this structure has obvious limitations. It can only prevent large-area water leakage and cannot fundamentally achieve complete anti-leakage. Especially when children are playing, they often swing the whole bottle back and forth. In this case, this structure cannot effectively prevent liquid leakage, resulting in the failure of the anti-leakage function.

[0005] In summary, the existing two anti-leakage bubble structures both have their own defects, bringing an unsatisfactory use experience to consumers. Therefore, it is urgent to develop a new method to achieve a more ideal anti-leakage function. Summary of the Utility Model

One end of the elastic support frame abuts against the vertical plate, and the other end is clamped with the sealing soft rubber. The sealing soft rubber is detachably abutted against the opening.

[0010] When the liquid-dipping blowing handle passes through and extends into the channel, the elastic support frame rotates and drives the sealing soft rubber to separate from the opening; when the liquid-dipping blowing handle is withdrawn from the extending channel, the elastic support frame returns to its original position and drives the sealing soft rubber to abut against the opening.

The V-shaped support hook is located between the hard skeleton and the vertical plate. One end of the V-shaped support hook abuts against the vertical plate, and the other end is clamped with the hard skeleton.

[0012] When the liquid-dipping blowing handle passes through and extends into the channel, the hard skeleton rotates and drives the sealing soft rubber to separate from the opening, and the V-shaped support hook contracts inward; when the liquid-dipping blowing handle is withdrawn from the extending channel, the V-shaped support hook returns outward, the hard skeleton returns to its original position and drives the sealing soft rubber to abut against the opening.

The covering part is located at the lower end of the hard skeleton, the rotating part is located at the upper end of the hard skeleton, and the clamping part is located on the side facing the vertical plate.

There is also a rotating hole between the vertical plate and the opening on the cover body. The rotating part is rotatably connected to the rotating hole, and the V-shaped support hook is clamped with the clamping part.

[0015] Preferably, the clamping part includes a clamping groove and an elastic positioning block. The V-shaped support hook is clamped in the clamping groove and abuts against the elastic positioning block.

[0016] Preferably, the hard skeleton further includes an elastic opening block. The elastic opening block is arranged on the side facing the opening. There is a notch on the sealing soft rubber that matches the elastic opening block, and the elastic opening block passes through the notch.

[0017] Preferably, the fixing part is a fixing hole. There is a fixing column on the sealing soft rubber corresponding to the fixing hole. There is an abutting bevel on the fixing column. The fixing column passes through the fixing column, and the abutting bevel abuts against the hard skeleton.

Detailed implementation manners

[0031] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0032] The object of the present utility model is to provide a leak-proof structure for a toy bubble water bottle to solve the problem of comprehensive and long-term effective leak prevention of the bubble water bottle.

[0033] As Figure 1 shown, the leak-proof structure of the toy bubble water bottle presented in this embodiment is composed of a water bottle 1, a liquid-dipping blowing handle 2, and a leak-proof bottle cap. Among them, the water bottle 1 serves as the overall bearing component, the leak-proof bottle cap is tightly connected to the bottle mouth of the water bottle 1, and the liquid-dipping blowing handle 2 penetrates through the leak-proof bottle cap, with one end extending into the water bottle 1 and a blowing port provided at the end.

[0034] As Figure 2 、 Figure 3 shown, the leak-proof bottle cap is further subdivided into a cap body 3 and a leak-proof structure 4 connected thereto. On the side of the cap body 3 facing the water bottle 1, an insertion channel 31 is provided, and an opening 33 is provided at the lower end of the insertion channel 31. At the same time, a vertical plate 34 is provided on the periphery of the cap body 3, and the vertical plate 34 is arranged opposite to the opening 33. The leak-proof structure 4 mainly includes an elastic support frame 41 and a sealing soft rubber 42. The elastic support frame 41 is rotatably connected to the cap body 3. Specifically, one end of the hard skeleton 411 of the elastic support frame 41 is flexibly rotatably connected to the cap body 3 through a rotating structure. The sealing soft rubber 42 can be detachably abutted against the opening 33. When the liquid-dipping blowing handle 2 passes through the insertion channel 31, the elastic support frame 41 rotates and drives the sealing soft rubber 42 to separate from the opening 33; when the liquid-dipping blowing handle 2 is withdrawn from the insertion channel 31, the elastic support frame 41 returns to its original position and drives the sealing soft rubber 42 to abut against the opening 33, which can effectively control the leakage of liquid when the blowing tool passes through and is withdrawn.

[0035] As Figure 4 shown, further, the elastic support frame 41 includes a hard skeleton 411 and a V-shaped support hook 412. The hard skeleton 411 is located between the vertical plate 34 and the opening 33. On the one hand, one end of the hard skeleton 411 is rotatably connected to the cap body 3, ensuring that the hard skeleton 411 can rotate smoothly during the operation. On the other hand, the other end of the hard skeleton 411 is combined with the sealing soft rubber 42 in a stable clamping manner, ensuring the reliability of the connection between the two. The V-shaped support hook 412 of the elastic support frame 41 is arranged between the hard skeleton 411 and the vertical plate 34. One end thereof is tightly abutted against the vertical plate 34, providing a stable support point for the elastic support frame 41, and the other end is firmly clamped to the hard skeleton 411, further enhancing the stability of the entire elastic support frame 41 structure.

[0036] As Figure 5As shown in the figure, specifically, the hard skeleton 411 includes a covering part 4111, a fixing part 4112, a clamping part 4113 and a rotating part 4114. The covering part 4111 is located at the lower end of the hard skeleton 411 and is specifically used to precisely sleeved the sealing soft rubber 42. Through this tight sleeving method, stable support and positioning are provided for the sealing soft rubber 42. The rotating part 4114 is located at the upper end of the hard skeleton 411 and is rotatably connected to a specifically designed rotating hole 35 on the cover body 3, thereby endowing the hard skeleton 411 with the ability to rotate around a specific axis. The clamping part 4113 is arranged on the side facing the vertical plate 34 and is mainly used to be clamped with the V-shaped supporting hook 412 to ensure that the V-shaped supporting hook 412 can stably cooperate with the hard skeleton 411 during operation. The sealing soft rubber 42 is precisely sleeved outside the covering part 4111 and is fixedly connected to the fixing part 4112. Specifically, the connection method is that the fixing part 4112 is designed as a fixing hole, and a fixing column 421 is correspondingly arranged on the sealing soft rubber 42, and an abutting inclined edge 422 is further arranged on the fixing column 421. The sealing soft rubber 42 is made of soft silicone material, which can facilitate passing it through the fixing hole. After the fixing column 421 passes through the fixing hole, the abutting inclined edge 422 abuts against the hard skeleton 411. This connection method not only realizes the firm connection between the sealing soft rubber 42 and the hard skeleton 411, but also can effectively prevent the sealing soft rubber 42 from loosening or detaching from the hard skeleton 411 during long-term use, thus ensuring the integrity of the leak-proof structure 4 and the continuous and stable exertion of the leak-proof function.

[0037] Furthermore, the hard skeleton 411 further includes a spring-opening block 4115. The spring-opening block 4115 is arranged on the side facing the opening 33, and a notch 423 matching the spring-opening block 4115 is arranged on the sealing soft rubber 42, and the spring-opening block 4115 passes through the notch 423. This design helps the hard skeleton 411 to more smoothly drive the sealing soft rubber 42 to separate from the opening 33 when the liquid-dipping blowing handle 2 passes through the insertion channel 31. The moving contact surface between the spring-opening block 4115 and the liquid-dipping blowing handle 2 is an inclined surface. The principle is that when the liquid-dipping blowing handle 2 penetrates into the insertion channel 31, it first squeezes the spring-opening block 4115 to shrink into the notch 423, and then drives the hard skeleton 411 to move. Since the rotating part 4114 of the hard skeleton 411 is rotatably connected to the rotating hole 35, under the action of the lever principle, the covering part 4111 of the hard skeleton 411 will drive the sealing soft rubber 42 to separate from the opening 33, facilitating the liquid-dipping blowing handle 2 to dip the bubble liquid. This structure enables the liquid-dipping blowing handle 2 not to directly contact the sealing soft rubber 42, avoiding the aging of the sealing soft rubber 42 due to repeated collisions, thus ensuring the long-term stable use of the structure.

[0038] Furthermore, referring to Figure 2, a rotation hole 35 is provided between the vertical plate 34 and the opening 33 on the cover body 3, and the rotating part 4114 is rotatably connected to the rotation hole 35, ensuring the accuracy and stability of the rotation of the hard skeleton 411. At the same time, the V-shaped support hook 412 is clamped with the clamping part 4113. The clamping part 4113 includes a clamping groove 4113a and an elastic positioning block 4113b. The V-shaped support hook 412 is precisely clamped in the clamping groove 4113a and abuts against the elastic positioning block 4113b. This clamping design makes the clamping of the V-shaped support hook 412 and the hard skeleton 411 more stable. During the operation of the blowing tool, even under the action of external force, the V-shaped support hook 412 will not easily separate from the hard skeleton 411, thus ensuring that the components of the leak-proof structure 4 can continue to work together, greatly improving the reliability and stability of the leak-proof structure 4.

[0039] Refer to Figure 3 , the extending channel 31 is also provided with a first sealing groove 311 and a second sealing groove 312. The first sealing groove 311 is above the opening 33 and is arranged opposite to the vertical plate 34. The second sealing groove 312 is at the lower end of the extending channel 31. A sealing strip 424 is provided on the sealing soft rubber 42. When the liquid-dipping blowing handle 2 is pulled out of the extending channel 31, the sealing strip 424 abuts against the first sealing groove 311, and the covering part 4111 drives the sealing soft rubber 42 to abut against the second sealing groove 312. Through this multiple sealing structure, sealing is carried out from multiple parts, further enhancing the leak-proof effect, effectively preventing liquid leakage, and effectively solving the problem that the existing structure cannot completely prevent leakage.

[0040] Among them, the contact surface between the second sealing groove 312 and the sealing soft rubber 42 is an inclined surface 3121. This design utilizes the principle that it is easier to seal and fit when in inclined surface contact, which helps the sealing soft rubber 42 to better fit with the second sealing groove 312, further enhancing the sealing effect. And when the water bottle 1 is inverted, the liquid in the bottle will also make the sealing soft rubber 42 fit better with the opening 33 under the action of pressure, making it more difficult for the liquid to leak from this sealing part, thus comprehensively improving the sealing performance of the entire leak-proof structure 4.

[0041] In addition, refer to Figure 2 、 Figure 3, the cover body 3 is further provided with a fixing ring 36, which is in interference fit with the cover body 3 and connected to the rotating hole 35, and the rotating part 4114 is located between the rotating hole 35 and the fixing ring 36. The setting of the fixing ring 36 has significant advantages in the production and installation process. It can provide accurate positioning and guidance for the installation of the hard skeleton 411, which is beneficial to improving production efficiency and installation accuracy. At the same time, the fixing ring 36 is connected to the rotating hole 35 to limit the position of the rotating part 4114, thereby realizing the fixed connection between the leak-proof structure 4 and the cover body 3. Moreover, it can further make the rotation of the hard skeleton 411 more stable and accurate, thus ensuring the reliability and stability of the entire leak-proof structure 4 during the operation of the blowing tool and ensuring that the leak-proof function is always effective.

[0042] During use, when the liquid-dipping blowing handle 2 passes through the insertion channel 31 of the leak-proof bottle cap, the liquid-dipping blowing handle 2 will touch the elastic block 4115, and then apply an extrusion force to the V-shaped support hook 412, causing the V-shaped support hook 412 to contract inward. This contraction drives the hard skeleton 411 to rotate through the clamping structure with the hard skeleton 411. The rotation of the hard skeleton 411 then drives the sealing soft rubber 42 to separate from the opening 33, allowing the liquid-dipping blowing handle 2 to pass through smoothly. When the liquid-dipping blowing handle 2 is withdrawn, the V-shaped support hook 412 loses the extrusion force and returns outward under its own elastic force, thereby driving the hard skeleton 411 to return to its original position, making the sealing soft rubber 42 abut against the opening 33 again to achieve sealing.

[0043] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
