Electronic snuffle valve device

Abstract

An electronic air escape valve device comprises an electronic control module, a three-way pipe fitting and a sliding sleeve piece. The electronic control module comprises a driving motor and a pressure sensor which are electrically connected with the control circuit board; the three-way pipe fitting is combined with a pressure sensor, and an air leakage hole is formed in one air channel; the sliding sleeve piece is sleeved on one of the gas channels and seals the gas release hole; therefore, when the gas pressure value of an external inflating object (such as a tire) is greater than the pressure relief value set by the control circuit board, the control circuit board controls the driving motor to start, and then the driving motor drives the sliding sleeve part to be far away from the gas relief hole of the three-way pipe fitting, so that the gas in the inflating object can be discharged from the gas relief hole of the three-way pipe fitting; therefore, the gas pressure value of the external inflation object can be detected, and whether an automatic deflation program is started or not can be accurately judged.

Description

TECHNICAL FIELD

[0001] The utility model relates to an electronic deflation valve device, and in particular to an electronic deflation valve device capable of detecting the gas pressure value of an external inflatable object and determining whether to start an automatic deflation program. BACKGROUND

[0002] Generally, vehicle tires or various inflatable objects (such as inflatable beds, inflatable boats, etc.) need to be inflated by an inflator as an auxiliary inflation device to effectively save manpower and time. In addition, for vehicle tires, an inflator is needed as an inflation device to accurately control the tire pressure and avoid insufficient or excessive tire pressure.

[0003] For vehicles (such as a sand buggy) in some special terrain and environment (such as a beach or a desert), the tire pressure needs to be deflated to below the general tire pressure value, such as below 2.4 bar (35 PSI), to allow the sand buggy to easily drive on the sand to avoid the tire sinking into the sand. Therefore, the deflation program operation required by the sand buggy is a very important control program for the sand buggy to drive on the sand.

[0004] However, the tire deflation operation is mainly completed manually by pressing the tire valve and deflating the tire. However, during the deflation process, in order to avoid excessive deflation of the tire, the user must repeatedly check the tire pressure with a pressure gauge. If the required deflation pressure value of the tire has not been reached, the user continues to deflate the tire manually. If the tire pressure is deflated too much, the tire must be inflated again by the inflator. Therefore, the repeated time-consuming and labor-intensive operation is very inconvenient.

[0005] Therefore, how to provide an electronic deflation valve device capable of detecting the gas pressure value of an external inflatable object to determine whether to start an automatic deflation program is the main problem to be solved by the present utility model. SUMMARY

[0007] Therefore, the internal gas of inflator flows into three-way pipe through gas chuck, first gas passage, and then the pressure value of internal gas of inflator is detected by pressure sensor, and when the pressure value of internal gas of inflator is greater than the relief value set by control circuit board, the drive motor is started by control circuit board, and then the second hollow sleeve of sliding sleeve component is driven away from the air release hole of third gas passage by the drive motor, so that the internal gas of inflator can be discharged from the air release hole, and the precise deflation function of inflator is achieved.
