[0002] Air valves are an essential component of all inflatable products. The performance of the air valve directly affects the performance of the inflatable product, especially medium to large-sized products such as inflatable tents, air mattresses, and inflatable boats. These products have high requirements for their air valves, which should possess the following characteristics: 1. Strong pressure resistance; 2. Good airtightness; 3. Large air volume for rapid inflation and deflation; 4. Easy and quick switching between deflation and sealing states; 5. Simple operation and safe use.

[0003] The existing technology has the following shortcomings;

[0004] Existing air nozzle products all adopt a double-seal design, which generally includes a first air nozzle body, sealant, and sealing plug. The sealant is installed inside the air outlet of the first air nozzle body, and the sealing plug covers the air outlet of the first air nozzle body. The sealant and sealing plug work together to prevent air leakage. However, with this type of air nozzle, the sealing plug needs to be removed and placed aside when inflating air, which makes it easy for the sealing plug to be lost during use and affect subsequent use.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 In this embodiment: an L-shaped three-in-one air nozzle includes a first body 1, a sealing cylinder 2 is fixedly installed at the bottom center of the first body 1, a sealing gasket 5 is provided inside the sealing cylinder 2, a sealing plug 201 is fixedly installed at the top of one end of the first body 1, a connecting cylinder 3 is fixedly installed at the top of the other end of the first body 1, and a connecting ring 301 is provided on the outer surface of the connecting cylinder 3.

[0022] In this embodiment, the first main body 1 is L-shaped and both ends of the first main body 1 are foldable. The first main body 1 has a connection hole 101 at the end corresponding to the sealing cylinder 2 and the sealing plug 201. An anti-slip strip 102 is fixedly installed on the side of the first main body 1 corresponding to the connection hole 101. By setting the anti-slip strip 102 and the connection hole 101, when it is difficult to remove the sealing cylinder 2 and the sealing plug 201, a rope can be passed through the connection hole 101 and pulled to remove them.

[0023] In this embodiment, a semi-circular sphere is fixedly installed inside the sealing plug 201. The first main body 1 is elliptical at one end corresponding to the sealing plug 201. A matching slot is provided at the top center of the first main body 1, and the outer surface of the sealing plug 201 matches the inner surface of the sealing cylinder 2. After the inflatable product is inflated, the sealing plug 201 is inserted into the inside of the sealing cylinder 2 to seal it, ensuring that the inflatable product will not leak air during use. At the same time, the sealing plug 201 and the connecting cylinder 3 are integrated to prevent the individual sealing plug 201 from being lost.

[0024] In this embodiment, a cross-shaped connecting frame 202 is fixedly installed inside the sealing cylinder 2. A limiting hole 203 is opened at the center of the connecting frame 202. A limiting rod 501 that matches the limiting hole 203 is fixedly installed at the center of the sealing gasket 5. The top of the limiting rod 501 corresponding to the limiting hole 203 is tapered. When deflating the inflatable product, the sealing plug 201 and the sealing cylinder 2 are moved out of the interior of the sealing cylinder 2 and the connecting cylinder 3, allowing the gas inside the inflatable product to flow out. This easily achieves the switching between the venting and sealing states, making operation convenient and providing good airtightness; it also has a large air volume and allows for rapid inflation.

[0025] In this embodiment, the outer surface of the sealing cylinder 2 is adapted to the inner surface of the connecting cylinder 3. Both the sealing cylinder 2 and the connecting cylinder 3 are provided with anti-slip grooves 4, and the outer surfaces of the sealing cylinder 2 and the sealing plug 201 are provided with first anti-slip textures adapted to the anti-slip grooves 4. By setting the anti-slip grooves 4 and the first anti-slip textures, when the sealing cylinder 2 and the sealing plug 201 are respectively inserted into the interior of the connecting cylinder 3 and the sealing cylinder 2, the anti-slip grooves 4 and the anti-slip textures cooperate to increase the stability of the connection and increase the airtightness when the inflatable product is sealed.

[0026] In this embodiment, an air cap nozzle 601 is fixedly installed at one end of the second main body 6, and the outer surface of the air cap nozzle 601 is also provided with anti-slip texture that matches the anti-slip groove 4. When inflating the inflatable product, the air cap nozzle 601 is inserted into the inside of the sealing cylinder 2, and then the air nozzle is placed inside the air cap nozzle 601 to inflate the inside of the inflatable product. The gas passes through the air cap nozzle 601, pushes open the sealing gasket 5, and flows into the inside of the product. When the inflation stops, the sealing gasket 5 returns to its original position to prevent the gas from flowing out. Then the air cap nozzle 601 is removed, and the sealing plug 201 is inserted into the inside of the sealing cylinder 2 to complete the sealing.

[0027] The working principle and usage process of this utility model are as follows: During use, the sealing plug 201 is removed from the inside of the sealing cylinder 2, and the air nozzle is inserted into the inside of the air cap 601 to inflate the product. Gas flows through the air cap 601, pushing open the sealing gasket 5 and into the product. When inflation stops, the sealing gasket 5 returns to its original position to prevent gas leakage. Then, the air cap 601 is removed, and the sealing plug 201 is inserted into the inside of the sealing cylinder 2 to seal it, ensuring that the inflatable product does not leak during use. When it is necessary to deflate the inflatable product, the sealing plug 201 and the sealing cylinder 2 are removed from the inside of the sealing cylinder 2 and the connecting cylinder 3, allowing the gas inside the inflatable product to flow out. This easily achieves the switching between venting and sealing states, is convenient to operate, and has good airtightness; it also features a large air volume and rapid inflation.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
