Abstract

The invention discloses a pressure detection device for a kitchen appliance, and the kitchen appliance. The pressure detection device comprises a base, a cover body, a rigid membrane, a magnetic piece, a sensing piece, and a detection unit, wherein the base is provided with a pressure leading hole; an accommodation chamber is defined by the cover body and the base; the rigid membrane divides the accommodation chamber into a mounting chamber and a pressure chamber, and is constructed to deform according to pressure changes of the pressure chamber; the magnetic piece moves according to deformations of the rigid membrane; the sensing piece is used to sense displacements of the magnetic piece; and the detection unit is used to acquire the pressure in the pressure chamber according to displacement information sensed by the sensing piece. The pressure detection device for the kitchen appliance disclosed by the embodiment of the invention has the advantages that the rigid membrane is adopted,so that the cost can be reduced, and the detection precision, the durability and the use reliability can be improved.

Description

technical field [0001] The present invention relates to the technical field of kitchen appliances, and more specifically, to a pressure detection device for kitchen appliances and the kitchen appliance. Background technique [0002] The active pressure sensor in the related technology needs to be connected to the power line to rely on the power supply, and the application occasions are limited, so it cannot meet the passive requirements; the passive pressure sensor in the related technology is realized by wireless power supply technology, and the reading signal is generally transmitted through wireless The communication protocol and circuit are complex and costly, which cannot meet the low-cost requirements of the product. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the present invention proposes a pressure detection device for kitchen appliances. The pressure detection...
