Title: PRESSURE SENSOR AND PRESSURE COOKER
Abstract:
Provided are a pressure sensor and a pressure cooker, the pressure sensor comprising: a base (1) provided with a cavity (11), and a pressure sensor element (2) mounted on the inside of said cavity (11); said cavity (11) is provided with a detection opening (111) to allow said pressure sensor element (2) to perform pressure detection and arranged on the opposite side of said pressure sensor element (2); the cavity (11) side located at the detection opening (111) is provided with a filtration mesh (3) for filtering between said cavity (11) and its external environment. Thus foreign materials or impurities are filtered by the filtration mesh, and foreign materials or impurities do not come into contact with the pressure sensor element, ensuring the good performance of the pressure sensor element.
