Description

Technical Field

[0001] This utility model relates to the field of air valves, specifically to a magnetic charging and discharging valve. Background Technology

[0002] With the improvement of living standards, more and more inflatable products such as inflatable pillows, inflatable toys, and inflatable massagers are appearing in people's lives. These inflatable products are equipped with air valves at the opening. When inflating, the air pump or other air source device pushes air into the product through the air valve to make the product full and usable. Therefore, the quality of the air valve directly affects the use of the product. The shortcomings of existing air valves are that the air valve structure is complex, the production and assembly are time-consuming, and it is inconvenient to use because it needs to be pressed to inflate and deflate. They are also prone to jamming and blockage. Utility Model Content

[0003] To address the shortcomings of existing gas valves, this utility model provides a magnetic charging / discharging valve with a stable structure that can be used for both charging and discharging. The specific technical solution is as follows:

[0004] A magnetic inflation / deflation valve includes an inflation head and an inflation base. The inflation head includes an inflation head bracket and a first magnetic element. The first magnetic element is mounted on the periphery of the inflation head bracket and protrudes from the bottom of the inflation head bracket. A first air channel is provided inside the inflation head bracket. The inflation base includes a shell, a second magnetic element, a soft rubber seat, an inner sleeve, a first elastic element, a plug cavity, an air inlet plug, a second elastic element, and an air outlet plug. The second magnetic element is mounted on the periphery of the shell and can be attracted to the first magnetic element. The soft rubber seat is fixedly mounted on the upper part of the inner sleeve. The soft rubber seat has a soft rubber chamber. When the inflation head touches the inflation seat, the first air passage connects to the soft rubber chamber. The inner sleeve is movably fitted inside the outer shell. The center of the inner sleeve is connected to the plug cavity. The plug cavity has a second air passage that connects to the soft rubber chamber. A first elastic element is installed in the upper part of the outer shell. The first elastic element contacts the inner sleeve. An air inlet rubber plug and a second elastic element are installed in the lower part of the plug cavity. Under normal conditions, the second elastic element drives the air inlet rubber plug to block the second air passage. An exhaust port is provided on the side of the plug cavity. An exhaust rubber plug is fixedly installed in the lower part of the outer shell. When the exhaust rubber plug is facing the exhaust port, it blocks the exhaust port.

[0005] As a preferred embodiment of this utility model, the outer shell is provided with a first chamber and a second chamber that are separated from each other. The upper part of the plug cavity is in the first chamber and the lower part is in the second chamber. The inner sleeve is movably fitted in the first chamber of the outer shell. A first elastic element is installed in the first chamber. The upper end of the first elastic element abuts against the inner sleeve and the lower end abuts against the inner wall of the first chamber. The exhaust plug is fixedly installed in the second chamber. When the intake plug moves down and no longer blocks the second air passage, the second air passage is connected to the second chamber.

[0006] As a preferred embodiment of the present invention, the inflatable head bracket is provided with multiple clearance grooves, which are distributed circumferentially around the central axis of the inflatable head bracket, and one end of the clearance groove is connected to the first air channel.

[0007] As a preferred embodiment of this utility model, the outer shell is made of metal material, and the upper end of the outer shell is provided with a step for attracting the first magnetic element, and the second magnetic element is located below the step.

[0008] As a preferred embodiment of this utility model, the inner sleeve is threadedly connected to the plug cavity, and a spring limiting plate is fitted at the bottom of the plug cavity. The upper end of the second elastic element abuts against the vent plug, while the lower end abuts against the spring limiting plate.

[0009] As a preferred embodiment of this utility model, the inflation head bracket is connected to the inflation head connecting pipe, which is used to connect the compressor pump and the deflation switch.

[0010] In a preferred embodiment of this utility model, the first elastic element and the second elastic element are springs.

[0011] As a preferred embodiment of this utility model, the first magnetic element is a permanent magnet.

[0012] Beneficial effects: When in use, the inflation head is firmly attracted to the inflation seat through the cooperation of the first and second magnetic elements. The bottom of the inflation head bracket protrudes and pushes against the soft rubber seat, inner sleeve, and end cap cavity, which then move downwards. External gas enters the soft rubber cavity and the second air channel through the first air channel, and the air inlet plug is pushed open. External gas enters the inflated product through the gap at the exhaust plug and the open gap at the air inlet plug. When deflation is required, the end cap cavity moves downwards and offsets the exhaust plug, so that the exhaust port is no longer blocked. The gas inside the inflated product can be discharged through the exhaust port. The magnetic structure design is stable and reliable, simple and convenient to operate, and quick to inflate and deflate, meeting the needs of various inflatable products.

[0021] like Figures 1-3 As shown, a magnetic inflation / deflation valve includes an inflation head A and an inflation seat B. The inflation head A includes an inflation head bracket 1 and a first magnetic element 2. The first magnetic element 2 is installed around the inflation head bracket 1, and the first magnetic element 2 protrudes from the bottom of the inflation head bracket 1. The inflation head bracket 1 has a first air channel 1a inside. The inflation seat B includes a shell 3, a second magnetic element 4, a soft rubber seat 5, an inner sleeve 6, a first elastic element 7, a plug cavity 8, an air inlet plug 9, a second elastic element 10, and an exhaust plug 11. The second magnetic element 4 is installed around the shell 3 and can be attracted to the first magnetic element 2. The soft rubber seat 5 is fixedly installed on the upper part of the inner sleeve 6. A soft rubber chamber 5a is provided. When the inflation head A abuts against the inflation seat B, the first air passage 1a connects to the soft rubber chamber 5a. The inner sleeve 6 is movably fitted inside the outer shell 3. The center of the inner sleeve 6 is connected to the plug cavity 8. The plug cavity 8 is provided with a second air passage 8a that connects to the soft rubber chamber 5a. A first elastic element 7 is installed in the upper part of the outer shell 3. The first elastic element 7 contacts the inner sleeve 6. An air inlet rubber plug 9 and a second elastic element 10 are installed in the lower part of the plug cavity 8. Under normal conditions, the second elastic element 10 drives the air inlet rubber plug 9 to block the second air passage 8a. An exhaust port 8b is provided on the side of the plug cavity 8. An exhaust rubber plug 11 is fixedly installed in the lower part of the outer shell 3. When the exhaust rubber plug 11 faces the exhaust port 8b, it blocks the exhaust port 8b.

[0022] Specifically, the outer shell 3 has a first chamber 3a and a second chamber 3b that are separated from each other. The upper part of the plug cavity 8 is in the first chamber 3a and the lower part is in the second chamber 3b. The inner sleeve 6 is movably fitted in the first chamber 3a of the outer shell 3. The first elastic element 7 is installed in the first chamber 3a. The upper end of the first elastic element 7 abuts against the inner sleeve 6 and the lower end abuts against the inner wall of the first chamber 3a. The exhaust plug 11 is fixedly installed in the second chamber 3b. When the intake plug 8 moves down and no longer blocks the second air passage 8a, the second air passage 8a is connected to the second chamber 3b.

[0023] Specifically, the inflation head bracket 1 is provided with multiple clearance grooves 1b, which are distributed circumferentially around the central axis of the inflation head bracket 1. One end of the clearance groove 1b is connected to the first air channel 1b from the side. The clearance groove 1b can be used to release air when the inflation head is abandoned. In addition, the outer shell 3 is made of metal material. The upper end of the outer shell 3 is provided with a step 3c for the first magnetic element 2 to be attracted. The second magnetic element 4 is located below the step 3c. When the inflation head approaches the inflation base, the first magnetic element of the inflation head and the outer shell of the inflation base will automatically be aligned and attracted together under the attraction of magnetism. The inflation head bracket and the outer shell are attached to form a sealed space.

[0024] Specifically, the inner sleeve 6 is connected to the plug cavity 8 by a central thread. The bottom of the plug cavity 8 is fitted with a spring limiting piece 12. The upper end of the second elastic element 10 abuts against the vent plug 11, while the lower end abuts against the spring limiting piece 12. In addition, the inflation head bracket 1 is connected to the inflation head connecting pipe 13, which is used to connect the compression pump and the venting switch.

[0025] Specifically, the first elastic element 7 and the second elastic element 10 are springs, and the first magnetic element 2 and the first magnetic element 4 are permanent magnets.

[0026] Working principle: When inflated, as... Figure 4 As shown, under the action of magnetic force, the inflation head bracket is attached to the outer shell. The bottom of the inflation head bracket 1 protrudes and pushes against the soft rubber seat 5, inner sleeve 6, and end cap cavity 8, causing them to move downwards. The downward movement of the end cap cavity offsets the exhaust plug, so that the exhaust port is no longer blocked. The inflation device inflates the first air channel 1a. The gas enters the soft rubber chamber 5a and the second air channel 8a through the first air channel 1a. The air inlet plug 9 is pushed open, and the external gas enters the second chamber 3b through the exhaust port and the gap at the opened air inlet plug, and then enters the inner cavity of the inflated product through the second chamber. Figure 5 As shown, when venting is required, no gas enters. The bottom of the inflation head bracket protrudes and pushes the soft rubber seat 5, inner sleeve 6, and plug cavity 8 downwards. The downward movement of the plug cavity offsets the vent plug, so that the vent is no longer blocked. Gas can also be discharged through the vent groove and connecting pipe on the end face of the inflation head bracket. Alternatively, venting can also be achieved by using external force to push the soft rubber seat, inner sleeve, and plug cavity downwards without using an inflation head.

[0027] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be considered that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the protection scope of the present utility model.
