Abstract
The utility model discloses a digital display tyre pressure meter for testing the tyre pressure, mainly comprising a switch sensor, a battery, a circuit board, a chip, and an LCD. The utility model is characterized in that the switch is a pneumatic switch. The utility model has reasonable structure, and effectively overcomes the defect of the traditional digital display tyre pressure meter that the function of automatic on and off in the using process can not be realized, and the user needs a process to master and understand while in use, realizing the function of automatic on and off with the convenience for the user to use, and embodying the people-oriented aim of the science and technology.
Description
Technical field:
The utility model relates to a kind of pick-up unit, particularly relates to a kind of device of detection wheel air pressure.
Background technology:
The present tyre digital pressure gauge that generally uses, its switch all are to adopt hand switch.The user can't realize the function of automatic open and close in the use, so need have a process of grasping and understanding in use.
Summary of the invention:
Technical problem to be solved in the utility model provides and a kind ofly can effectively overcome above-mentioned defective, can realize the tyre digital pressure gauge of automatic open and close.The technical scheme that its technical matters that solves the utility model adopts is that a kind of tyre digital pressure gauge mainly is made up of switch, sensor, battery, circuit board, chip and LCD etc.Its characteristics are: described switch is a pneumatic switch.Owing to adopt such scheme, to be not difficult to draw and to the utlity model has following beneficial effect, the utility model is rational in infrastructure, be skillfully constructed, realized the function of automatic open and close, thus convenient for users to use, embodied the science and technology aim that people-oriented, the tool promotional value.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is described in further detail.
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
Among the figure, this tyre digital pressure gauge mainly is made up of pneumatic switch 2, sensor 3,3V lithium battery 8, circuit board 9, chip 7 and LCD6.Wherein sender unit cap 1 can play the effect of seal sensor 3 and pneumatic switch 2, makes sensor 3 experience air pressure.4 of battery covers can sealed cell 8, fixed L CD6 and zebra bar 5 simultaneously.LCD6 is connected with circuit board 9 by zebra bar 5, and the digital signal of chip 7 outputs shows its corresponding value by LCD6.The effect of pneumatic switch 2 is when air pressure is arranged, its conductive rubber is depressed, the circuit of conductive rubber on can the connecting circuit plate, wake chip 7 up, give sensor 3 power supplies, sensor is started working, when not having air pressure, conductive rubber utilizes the elasticity of self to flick, shut-off circuit, thereby the function of realization automatic switch.
