Abstract

The invention discloses a pressure sensor and a cooking utensil with the same. The pressure sensor comprises a sensor body, a flexible seal piece, a moving part, sensing parts and a controller. A pressure cavity with an open end is defined inside the sensor body, and an air hole communicated with the pressure cavity is formed in the sensor body; the flexible seal piece is arranged at the open end of the sensor body to close the open end, and arranged to deform toward the interior of the pressure cavity when outer side air pressure of the open end is larger than air pressure inside the pressure cavity; the moving part is arranged on the flexible seal piece and moves along with deformation of the flexible seal piece; the sensing part is arranged to adapt to sense the displacement of the moving part; the controller is connected with the sensing part to calculate the outer side air pressure at the open end according to the displacement information sensed by the sensing part. According to the embodiment of the pressure sensor, the structure is simple, circuits are simple, the structure of an installation carrier and the assembly process of the pressure sensor are easily simplified, pressure values under application conditions can be detected, and using is safe.

Description

technical field [0001] The present invention relates to the technical field of household electrical appliances, and more particularly, to a pressure sensor and a cooking appliance having the pressure sensor. Background technique [0002] At present, the pressure sensors used in pressure cookers are resistance strain gauge pressure sensors, semiconductor strain gauge pressure sensors, piezoresistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, etc. These pressure sensor circuit connections are complicated, which affects the pressure of the pressure cooker.
