Description

Technical Field

[0001] The present application relates to the technical field of gas valves, and in particular to a switch ventilation valve. Background Art

[0002] An air valve is a device used to control the flow of gas. When used in inflatable products, it is usually a small valve that facilitates inflation or deflation. Most of these small valves are made of materials such as plastic or silicone, and have a simple structure and are easy to use, so they are widely used in daily life.

[0003] In the related art, in order to improve the safety of inflatable products, multiple air cavities are usually separated in large inflatable products such as inflatable tents, inflatable boats, inflatable arches, etc., to prevent the overall structure from being deformed and unstable due to damage and leakage of one of the air cavities. These air cavities are usually connected by a one-way valve with a rubber sealing sheet. Such air valves can not only keep the air cavities connected during inflation, but also keep the air cavities closed to a certain extent after inflation.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the various air cavities in the inflatable product are connected by a one-way valve. When one of the air cavities is damaged and leaks, the gas in the air cavity on the air inlet side of the air cavity during inflation will still flow into the air cavity through the one-way valve, thereby aggravating the leakage and eventually causing the overall structure of the inflatable product to deform and become unstable, resulting in lower safety. Utility Model Content

[0005] In order to improve the problem that when one of the air cavities of an inflatable product is connected by a one-way valve, leakage may occur in other air cavities when one of the air cavities is damaged, the present application provides a switch ventilation valve.

DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] The present application embodiment discloses a switch vent valve. Figure 1 and Figure 2 The switch vent valve comprises a first valve body 1 and a second valve body 2. The first valve body 1 is partially slidably arranged in the second valve body 2. Specifically, the first valve body 1 is a hollow structure, and one end located outside the second valve body 2 is open, and the other end located inside the second valve body 2 is closed. A connecting port 11 is penetrated through the side wall of the first valve body 1 for connecting to the second valve body 2. In addition, a sealing component 3 is further provided on the first valve body 1. The sealing component 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. The first sealing ring 31 and the second sealing ring 32 are both sleeved on the outer wall of the first valve body 1, and the first sealing ring 31 is arranged on the side of the connecting port 11 close to the second valve body 2, and the second sealing ring 32 is arranged on the side of the connecting port 11 away from the second valve body 2.

[0022] Reference Figures 1 to 3 The second valve body 2 is also a hollow structure, and one end away from the first valve body 1 is open. In the embodiment of the present application, the inner diameter of the second valve body 2 is three-stage, and is gradually reduced in the direction away from the first valve body 1. It should be noted that the second valve body 2 can be adapted to the gas valve base in the prior art for use, and the installation relationship has been Figure 1 Therefore, when the first valve body 1 moves toward the inside of the second valve body 2, the first sealing ring 31 and the second sealing ring 32 on the first valve body 1 can both be pressed against the inner wall of the second valve body 2, the first sealing ring 31 can seal the end of the second valve body 2, so that it is difficult for gas to flow through the connecting port 11 in the first valve body 1 and the second valve body 2, and the second sealing ring 32 can seal the gap between the first valve body 1 and the second valve body 2, so that it is difficult for gas to flow through the gap between the first valve body 1 and the second valve body 2, thereby improving the sealing effect of the entire vent valve.

[0023] Reference Figure 1 and Figure 2In order to enable the first valve body 1 to move in the second valve body 2, a driving assembly 4 is provided on the first valve body 1 and the second valve body 2. Specifically, the driving assembly 4 includes a driving cover 41 and a driving hoop 42. The driving cover 41 is threadedly connected to the second valve body 2. The driving hoop 42 is clamped on the first valve body 1 and is located on the side of the driving cover 41 facing away from the second valve body 2. In addition, a plurality of transmission ridges 5 are integrally formed on the first valve body 1. The plurality of transmission ridges 5 are arranged at intervals along the circumference of the first valve body 1 and are located on the side of the driving cover 41 facing the second valve body 2. Therefore, when the driving cover 41 is tightened, the driving cover 41 will press against the transmission ridges 5 and drive the first valve body 1 to move toward the inside of the second valve body 2, thereby closing the second valve body 2; when the driving cover 41 is loosened, the driving cover 41 will press against the driving hoop 42 and drive the first valve body 1 to move toward the outside of the second valve body 2 through the driving hoop 42, thereby opening the second valve body 2.

[0024] To summarize, when the inflatable product is inflated, the vent valve can be put in an open state by loosening the drive cover 41 to drive the first valve body 1 to move toward the outside of the second valve body 2. At this time, the air cavities connected to the vent valve are in a two-way connected state, so that the inflatable product can be fully inflated; when the inflatable product is completely inflated, the vent valve can be put in a closed state by tightening the drive cover 41 to drive the first valve body 1 to move toward the inside of the second valve body 2. At this time, the air cavities connected to the vent valve are in a two-way sealed state. Therefore, when any of the air cavities is damaged, the gas in the other air cavities will not flow into the air cavity through the vent valve, thereby maintaining the overall structural stability of the inflatable product and improving the safety of the inflatable product.

[0025] Reference Figure 2 and Figure 3 In order to prevent the first valve body 1 from completely separating from the second valve body 2 when moving toward the outside of the second valve body 2, a limit card 6 is provided on the second valve body 2. In the embodiment of the present application, the limit card 6 is in a U-shaped structure to avoid the first valve body 1. The outer wall of the second valve body 2 is also provided with a receiving groove 21 adapted to the limit card 6. The limit card 6 is inserted into the receiving groove 21 and penetrates the second valve body 2. In addition, a limit hole 51 is provided on the transmission edge 5 along the moving direction of the first valve body 1. The limit card 6 penetrates the second valve body 2 and then passes through the limit hole 51. Therefore, when the driving component 4 drives the first valve body 1 to move toward the outside of the second valve body 2, under the limiting effect of the limit card 6, the first valve body 1 will not separate from the second valve body 2. At the same time, the limit card 6 can also limit the first valve body 1 from rotating in the second valve body 2, thereby improving the convenience of use of the entire vent valve.

[0026] Reference Figure 1 and Figure 2A twist ring 7 is integrally formed on the outer wall of the second valve body 2 along its circumference, and a plurality of twist grooves 71 are spaced apart at the edge of the twist ring 7. Therefore, when the drive cover 41 is twisted, the twist ring 7 can facilitate the hand to hold the second valve body 2, and the plurality of twist grooves 71 can also provide a better fulcrum for the hand, thereby making the drive cover 41 easier to twist.

[0027] Reference Figure 1 and Figure 2 In order to improve the applicability of the vent valve, a fixing cover 8 is threadedly connected to one end of the first valve body 1 away from the second valve body 2. Therefore, when it is necessary to connect two air cavities on the inflatable product that are far apart, an air hose can be sleeved on the end of the first valve body 1 to increase the usable length. After the air hose is sleeved on the end of the first valve body 1, the air hose can be pressed against the end of the first valve body 1 by tightening the fixing cover 8, so that the air hose is not easy to fall off from the first valve body 1, thereby improving the stability of the entire vent valve.

[0028] The implementation principle of a switch vent valve in the embodiment of the present application is as follows: when the inflatable product is inflated, the vent valve can be put in an open state by loosening the drive cover 41 to drive the first valve body 1 to move toward the outside of the second valve body 2. At this time, the air cavities connected to the vent valve are in a two-way connected state, so that the inflatable product can be fully inflated; when the inflatable product is completely inflated, the vent valve can be put in a closed state by tightening the drive cover 41 to drive the first valve body 1 to move toward the inside of the second valve body 2. At this time, the air cavities connected to the vent valve are in a two-way sealed state. Therefore, when any of the air cavities is damaged, the gas in the other air cavities will not flow into the air cavity through the vent valve, thereby maintaining the overall structural stability of the inflatable product and improving the safety of the inflatable product.

[0029] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
