Internal/external air switching device with oxygen sensor of automobile

摘要

This research is about the internal and external gas switch device with automobile oxygen induction sensor. The partition board (80) can be set between the external gas inlet (90) and the internal gas inlet (100),Connecting the rotating shaft (80A) of the shield plate (80), rotating the sector gear (70) and the shield plate (80) at a specific angle,In accordance with the sector gear (70), driven by the driving motor (40), the driving drive of the sector gear (70) drives the driving gear (60) andMycom (20) and controlling the driving amount of the driving motor (40),In order to adjust the mycom (20), the mycom (20) is composed of an oxygen sensor (10) which senses a small amount of oxygen flowing into the external air inlet (90), and is an internal and external air switch device with an automobile oxygen sensor,This is to prevent the polluted air from entering the room and keep the room fresh and comfortable all the time.
