Pressure sensor

Abstract

A pressure sensor including a first air cover and a second air cover and a pressure sensing component, the pressure sensing component sandwiched between the first and the second air cover. The chamber between the first and the second air cover is partitioned by the pressure sensing component into an upper and a lower chamber. The second air cover has a peripheral wall and on the inner side surface of the peripheral wall a hook is provided. The outer side of the first air cover is formed with a matching engagement structure that is mutually engaged with the hook of the second air cover. The bottom of the second air cover is provided with a communication channel and, except for the communication channel, is a fully enclosed structure. The pressure sensor effectively prevents foreign objects from entering, does not interfere with sensor performance, and is convenient for assembly.
