specific Embodiment approach

[0013] Align the screw-in nozzle (3) of the transmitter with the tire nozzle and tighten it, screw the anti-lost and anti-theft jacking wire (19) into the jacking wire hole (18), and tighten it. The valve needle exerts pressure to make it move inward, so that the air in the tire is leaked into the airtight chamber (5) of the alarm transmitter, and under the action of air pressure, the adhesive film (6) expands, moves to the right and moves with the movable conductive metal sheet ( 8) are in contact with each other. Under normal pressure, (8) will overcome the force of the spring and move to the right, separating from the circular conductive metal sheet, so that the wire (14), circular conductive metal sheet (7), movable conductive The power switch composed of metal sheet (8) and conductive spring (9) is disconnected, the current is cut off, and the transmitter will not work. Finally, touch (16) and (15) with your fingers at the same time to release the internal circuit from the...

Abstract

A radio-type full-automatic leakage alarm for tyre of motor-driven vehicle is composed of a miniature radio transmitter fixed to air valve of tyre, a switch controlled by the air pressure in tyre and a radio receiver installed in the driver cab. When the air pressure in tyre is reduced to a threshold due to leakage, the switch is triggered to turn on the radio transmitter for transmitting leakage signal. The signal is received by the said receiver to generate an audio alarm which indicating corresponding numerals.

Description

Technical field [0001] This patent relates to a wireless alarm device capable of remotely measuring tire leakage, especially for large vehicles in operation. Background technique [0002] At present, known tire leak alarms are realized by utilizing the size variation of the air pressure to control the alarm bar-shaped ground contact switch. Even if some alarms can report to the police, they cannot accurately inform the location of the damaged tire. It cannot be automatically controlled. The disadvantages of the above two are: the reliability will be affected by the roughness of the ground, and it will also bring troubles to the user to replace the battery frequently. Contents of the invention [0003] In order to overcome the lack of reliability and economy of the existing alarm devices, this patent provides an alarm that can not only remotely measure the position of the flat tire in operation, but also automatically shut down the transmitter after 0.5 seconds after launch...
