Description

Technical Field

[0001] This application relates to the field of air valve technology, and in particular to a switch connection valve. Background Technology

[0002] In the field of inflatable products, some products often adopt a multi-chamber design, which means that a single chamber is physically separated to form multiple independent chambers. The advantage of this design is that if one chamber is damaged and leaks air, the other chambers can still maintain the overall structure and avoid complete failure. Due to its high safety and stability, it is widely used in life-saving equipment, inflatable furniture and outdoor equipment.

[0003] In the prior art, for inflatable products with a multi-chamber design, each chamber is usually equipped with a separate inflation valve, or a one-way valve is used to connect the chambers so that the inflatable product can be inflated and deflated normally. However, the above methods are difficult to actively and quickly adjust the air pressure distribution of each chamber to avoid leakage risk in certain emergency situations (such as when a chamber is damaged), and cannot balance safety and flexibility. Utility Model Content

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a switch connection valve. (Refer to...) Figures 1 to 5 The switch-connect valve consists of a switching mechanism and a connecting mechanism. The switching mechanism includes a valve seat 1 and a valve core 2. Specifically, a first gas passage 11 is formed in the valve seat 1, and both ends of the valve seat 1 are open to allow the valve core 2 to slide within the valve seat 1. A second gas passage 21 is formed in the valve core 2, and one end of the valve core 2 inside the valve seat 1 is closed, while the other end outside the valve seat 1 is open. In addition, a through hole 22 is provided through the outer wall of the valve core 2 to connect the first gas passage 11 and the second gas passage 21.

[0031] Reference Figure 3 and Figure 5The switching mechanism also includes a sealing assembly 3. Specifically, the sealing assembly 3 consists of a first sealing ring 31 and a second sealing ring 32. The diameter of the first sealing ring 31 is smaller than the diameter of the second sealing ring 32. Both the first sealing ring 31 and the second sealing ring 32 are fitted onto the valve core 2. The first sealing ring 31 is located on the side of the through hole 22 near the sealing end of the valve core 2, and the second sealing ring 32 is located on the side of the through hole 22 near the open end of the valve core 2. Furthermore, the inner wall of the valve seat 1 has two inner diameter sections distributed along its own axial direction. These two inner diameter sections correspond one-to-one with the first sealing ring 31 and the second sealing ring 32. The inner diameter section corresponding to the first sealing ring 31 is smaller and fits the first sealing ring 31, while the inner diameter section corresponding to the second sealing ring 32 is larger and fits the second sealing ring 32. Therefore, when the valve core 2 is inserted into the valve seat 1 until both the first sealing ring 31 and the second sealing ring 32 are pressed against the inner wall of the valve seat 1, the valve core 2 is in a sealed position, thereby blocking the first gas passage 11 to achieve a sealing effect.

[0032] Reference Figure 2 and Figure 3 The switching mechanism also includes a drive assembly 4. Specifically, the drive assembly 4 consists of a cap 41 and a clamp 42. The cap 41 is threaded onto the valve seat 1. The outer wall of the valve core 2 has a mounting groove 23 on the side of the cap 41 facing away from the valve seat 1 along its own circumference. The clamp 42 is fitted into the mounting groove 23 and partially located outside the mounting groove 23. In addition, an outer ring 7 is integrally formed on the side of the cap 41 facing the valve seat 1 along its own circumference. The two sides of the cap 41 abut against the clamp 42 and the outer ring 7, respectively. Therefore, when the cap 41 is loosened, the cap 41 abuts against the clamp 42 and drives the valve core 2 to slide outward toward the valve seat 1. When the cap 41 is tightened, the cap 41 abuts against the outer ring 7 and drives the valve core 2 to slide inward toward the valve seat 1.

[0033] When the aforementioned switching mechanism is controlled to open and close, if the cap 41 is loosened, the valve core 2 can slide towards the outside of the valve seat 1. When the first sealing ring 31 slides into the larger inner diameter section of the valve seat 1, the first gas passage 11 and the second gas passage 21 are connected, and the switching mechanism is opened to keep the gas flowing. If the cap 41 is tightened, the valve core 2 can slide towards the inside of the valve seat 1. When the first sealing ring 31 slides back into the smaller inner diameter section of the valve seat 1, the first gas passage 11 and the second gas passage 21 are blocked, and the switching mechanism is closed to isolate the gas.

[0034] Reference Figure 3 and Figure 4The outer wall of the valve core 2 is provided with a slot 24 through it along its sliding direction. The valve seat 1 is equipped with a pin 8 corresponding to the slot 24. Specifically, the outer wall of the valve seat 1 is provided with a receiving groove 12. The pin 8 is adapted to be embedded in the receiving groove 12 and penetrates the outer wall of the valve seat 1. The part of the pin 8 that penetrates the outer wall of the valve seat 1 is inserted into the slot 24. Therefore, when the valve core 2 slides in the valve seat 1, the valve core 2 will not slip out of the valve seat 1 under the limiting action of the pin 8, thus preventing the overall structure from failing.

[0035] Reference Figure 1 The connecting mechanism includes a first connecting component 5 and a second connecting component 6. Specifically, the first connecting component 5 consists of a connecting pipe 51 and a connecting seat 52. The connecting pipe 51 is installed at the end of the valve seat 1 and connected to the first gas channel 11. The connecting seat 52 is installed at the end of the connecting pipe 51 away from the valve seat 1 and connected to the connecting pipe 51. Therefore, by installing the connecting seat 52 at the preset inflation port position of the inflatable product, one of the air chambers can be connected to the switching mechanism. In this embodiment, the structure and function of the second connecting component 6 are exactly the same as those of the first connecting component 5. The second connecting component 6 is installed at the end of the valve core 2 and connected to the second gas channel 21. After installing the second connecting component 6 with the inflatable product, the other air chamber can be connected to the switching mechanism. After installation, the gas flow or isolation between the two air chambers can be achieved by controlling the switch mechanism, thereby enabling active and rapid adjustment of the air pressure in the two air chambers to avoid leakage risks and balance safety and flexibility. In addition, during actual use, multiple switch connection valves can be set according to the specific number of air chambers in the inflatable product to facilitate the adjustment of the air pressure in each air chamber.

[0036] Reference Figure 1 In this embodiment, the connecting seat 52 is designed as a conical structure, and the inner diameter of the connecting seat 52 gradually increases in the direction away from the connecting pipe 51, so as to keep the gas flow as unobstructed as possible. In addition, an expansion ring 9 is integrally formed along its circumference at the outer edge of the connecting seat 52 away from the connecting pipe 51. The expansion ring 9 can provide a larger contact area when the connecting seat 52 is fixedly connected to the inflatable product, thereby obtaining better sealing performance and making it less likely for gas to leak out.

[0037] The implementation principle of a switch connection valve in this application embodiment is as follows: the first connecting component 5 and the second connecting component 6 are respectively connected to the preset inflation port position of the inflatable product and connected to the air chamber. Then, by turning the cap 41, the valve seat 1 and the valve core 2 are controlled to open or close, so as to realize the gas flow or isolation between the two air chambers. This allows for active and rapid adjustment of the air pressure in the two air chambers to avoid leakage risks and to balance safety and flexibility.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
