Description of the new type: [Technical field to which the new type belongs] This creation relates to an electronic wireless tire pressure detector, especially a type in which the electronic detection element and the power supply body are all located outside the tire, which can reach the outside of the tire. Those who can directly send messages and replace the power supply body or perform maintenance. [Previous technology] Press, after a period of driving, or after exposure to sunlight and night temperature drop, it is easy to produce a pressure relief situation, which makes the tire pressure lower than the normal value of 28psi, which is a potential danger for driving safety Performance, especially in high-speed vehicles, such as when the tire pressure explodes due to insufficient pressure, the consequences are even more unimaginable. Therefore, many manufacturers have invested in research and development of tire pressure detection and warning devices during driving. This type of patent is found in the public notice No. 536489, 400811, 149143, 177543, 560445, 574977, 090946, 100539 No. and 396974 and other pre-patent cases. In the pre-patent case of the conventional patent, it can be roughly divided into electronic detection and mechanical detection. Among them, the mechanical detector has a short life, large volume and poor accuracy. Since it is not the object of this creative improvement, it will not be described in detail. As for the electronic tire pressure detector, it is mainly a hidden tire pressure detector with the tire pressure detector installed on the inner rim of the tire. This type of patent is found in the public notices 404354, 578706, and 578707. No. and other patents. The advantage of this type is that the tire pressure detector is hidden in the tire and can directly measure the tire pressure of M280310. Its main structure is shown in the first and second figures, including a group of shells (11), one is located in the shell (11) a detector circuit board (12), the circuit board (12) has a signal transmitting antenna (13), and two batteries (14) for supplying power to the circuit board (12), and the case ( 11) A gas nozzle (15) is connected to the front end. When the aforementioned components are assembled into a tire pressure detector (10), as shown in the second figure, it is fixed on a steel ring (21) inside the tire (20), and the air nozzle (15) penetrates the steel ring. (21), then use a gasket (16) and a nut (17) to fix, and finally lock the cover (18) to complete the assembly. The tire pressure detector (10) used in the previous exercise, when it detects abnormal tire pressure, sends a signal through the transmitting antenna (13), which is received by a receiver (not shown in the figure) installed in the car, thereby obtaining Know abnormal tire pressure. However, it is found that the transmitting antenna (13) is located in the moon σ (20), which is susceptible to blocking and affects the transmission of the signal, resulting in poor accuracy and reliability, which is not perfect. Second press, U.S. Patent No. 5,798,689 also discloses a tire pressure debt detector hidden in the air of a vehicle tire, and it is a hidden type like the above-mentioned patent. The further disadvantage is that these hidden tire pressure detection The batteries need to supply the power required for operation, but these tire pressure devices are hidden inside the pneumatic tires. The battery has limited power. It is often difficult and cumbersome to replace the battery. It must be removed from the vehicle. Removing the tire, money, removing the pneumatic tire, disassembling the tire pressure detector, replacing the battery, and then reading it back in reverse after changing the battery causes the complexity and difficulty of replacing the battery. Knowing the shortcomings, the creator has accumulated many years of experience in the industry, and after measuring the research and development, he finally invented the creation and fully improved the lack of knowledge.

When the tire tester is locked in the air nozzle, the power is supplied, and when it is removed, it is automatically disconnected to save power and prevent false alarms. -According to the previous release, when the connector is screwed to the tire valve, the top surface of the pin is the control valve of the valve to allow the tire to enter the airtight chamber and the power source of the battery passes through the pin holder and the pin. To the gas nozzle, and the gas nozzle conducts back to the housing and passes to the __circuit board-shaped money conduction (0N) power supply circuit; when the tire tester is disassembled from the wheel platform gas nozzle, then Automatically open (OFF) state. In this way, in addition to the front-reveal effect of this creation, when installing this creation, you don't need to disassemble the tires, you only need to lock it on the valve, which is convenient for assembly and can be inspected and repaired at any time. Furthermore, compared with the conventional mechanical wireless tire pressure detector, it has the advantages of small size, easy failure and high accuracy because it does not require moving parts such as springs and pistons.
