Description of the Invention: [Technical Field] The present invention relates to a tire pressure detector, and more particularly to a nozzle-type tire pressure detector that is sleeved on a tire nozzle. [Prior Art] Tire pressure inspection is the first step in tire maintenance, but it is also the part most often ignored by car owners. The adequacy of tire pressure is related to the grip and service life of the tire. It also has a profound impact on the fuel consumption of the vehicle. Therefore, the tire pressure system needs regular inspection. When the tire pressure is insufficient, the tread will increase the contact area with the ground, which will increase the frictional force, increase the engine load and increase the fuel consumption, and the drainage performance of the tire will also decrease. It is easy to slip at high speeds on rainy days, and the tires will form an uneven wear state with a shallow tread pattern over a long period of time. When the tire rotates on the road surface, the second sidewall is often deformed by large deflection, which makes the internal temperature easy to rise, and the high-speed driving has a crisis of puncture. When the tire pressure is high, the rabbit may be inflated due to excessive force. In the long period of time, the tire f will form an uneven wear state with shallow tread, and the stability of the car will be reduced due to the tread. , grinding secrets; the job of people to come to the comfort of the tires due to the hardening of the tires to avoid the image and shorten the life of the tires. The tires of the positive medium - and the second: the surface area and the ground with the largest area of the dish will make the monthly contact. At this time, the optimal drainage and grip of the tires are fully utilized and the most fuel-efficient. Therefore, it is one of the subjects of effectively controlling the tire pressure and the fetal heart of the tire. The county has been provided with a combination of the 201117974 tire pressure gauge and the tire nozzle. According to Item 1 (a), the tire pressure debt measuring device i is installed in the air nozzle 100 of a tire 10, and then is fitted by a nozzle cover to complete the installation. However, there are several disadvantages to this type of installation: First, if the tire pressure detecting device 1 is to be installed, it is necessary to first remove the tire and replace the dedicated nozzle 100' so that an original nozzle is wasted. Secondly, the tire pressure detection (4) is installed in the gas nozzle 100. The RF signal transmitted by the tire pressure is transmitted through the nozzle cover 11 and the tire 10, and the transmission efficiency is poor, and the tire pressure misjudgment is also likely to occur.
