[0018] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] A novel TPU air valve comprises a valve body, a valve core 9, and a cap 4. The cap 4 is mounted on the body and made of soft TPU material for easy installation on a tire. The valve core 9 is mounted within the body, which includes a rubber ring 2 and a support ring 8. The inner sidewall of the rubber ring 2 is fixedly connected to the outer sidewall of the support ring 8, and the valve core 9 is mounted within the support ring 8.

[0021] The mouth cap 4 is connected to the rubber ring 2, and the mouth cap 4 is connected to the support ring 8. The outer wall of the rubber ring 2 is fixedly provided with a support strip 3. There are multiple support strips 3 on the rubber ring 2. The rubber ring 2 and the support strips 3 are integrally formed. The support strips 3 play a supporting role and increase the strength of the main body.

[0022] The rubber ring 2 is made of a hardened TPU material. This thermoplastic polyurethane elastomer, also known as thermoplastic polyurethane rubber (TPU), offers excellent overall properties, including high strength, toughness, wear resistance, and oil resistance, extending the life of the main body. The support ring 8, made of a hardened elastic material, provides support for the main body. The combination of the rubber ring 2 and support ring 8 ensures the main body is wear-resistant, oil-resistant, highly tough, and strong, making it less susceptible to deformation and damage, thereby extending its service life.

[0023] A threaded tube 6 is provided at the end of the main body away from the mouth cap 4, and the threaded tube 6 is threadedly connected to the cover cap 1. A clamping block 5 is fixedly provided inside the cover cap 1. The clamping block 5 is clamped on the end of the main body close to the cover cap 1. The cover cap 1 plays a role in ensuring the airtightness of the main body, and the clamping block 5 further ensures the airtightness between the main body and the cover cap 1.

[0024] The clamping block 5 is made of a rubber material, which is elastic and facilitates its attachment to the main body. A limit ring 7 is fixed to the side of the main body away from the mouth cap 4. The clamping block 5 has a limit groove. When the clamping block 5 is attached to the main body, the limit ring 7 is located in the limit groove, further enhancing the airtightness between the cap 1 and the main body.

[0025] The implementation principle of this embodiment is: when the main body of the valve nozzle is subjected to external impact, since the main body is composed of a rubber layer and a support layer, and the rubber layer is made of TPU material with a certain hardness, and the support layer is made of an elastic material with a certain hardness, the main body has the characteristics of wear resistance, oil resistance, high strength, high toughness, etc., and the main body is not easily deformed and damaged by force, thereby achieving the effect of extending the service life of the valve nozzle.
