The present invention relates to a vehicle air nozzle, and more particularly to a air nozzle for a wireless tire pressure sensing device and a wireless tire pressure sensing device using the same.

Tire Pressure Monitoring System (TPMS) can be divided into direct TPMS and indirect TPMS. Direct TPMS directly monitors the air pressure of the tire by using a pressure sensor installed in the tire to ensure the tire pressure. Stable, and the indirect TPMS compares the speed difference between the wheels through the wheel speed sensor of the anti-lock brake system of the car to achieve the effect of monitoring the tire pressure. Due to the advancement of wireless technology, the direct TPMS has gradually become a variety of vehicles. The trend of assembly needs to be assembled.

The existing tire pressure detecting system is installed inside the wheel frame, and is connected with the electronic system in the vehicle by wireless communication, thereby transmitting the tire pressure information to the user, in order to be able to wirelessly test the tire pressure detecting system. The pressure sensor is installed inside the wheel frame, and generally uses a metal inflation nozzle to pass through the wheel frame. The air nozzle includes a body and a jacket. The system has two ends and a connecting end and a An inflation end, the connection end is located inside the wheel frame and is sleeved with the wireless tire pressure sensor corresponding to the shape of the wireless tire pressure sensor, and is axially penetrated by the wireless tire pressure sensor Locking the air nozzle on the wireless tire pressure sensor, the inflatable end protrudes out of the wheel frame, the outer cover is made of rubber material and a rubber outer cover is fixed to the outer circumference of the body by a gluing technique, and the rubber outer casing is utilized Closely fitting with the wheel frame can provide an airtight effect; since the tire is filled with ozone, the rubber is easily oxidized by the action of ozone, causing the outer casing to become brittle and lose its elasticity, so the gas nozzle is often replaced every other year. Conventional air nozzle which is glued in one coat system can not easily separated from the air nozzle, heating is required to melt or rubber jacket with direct damage to equipment, and therefore more difficult to replace the gas nozzle, often you need to store a specific replacement.
