Magnetic steel sensor

Abstract

The invention discloses a magnetic steel sensor which comprises the components of a large cup which is vertically provided with holes, the large cup is provided with a circumferential flange, and theside surface of the large cup is provided with an M-shaped hole; the outer spring is arranged in the big cup, and the free height of the outer spring is larger than the height of the big cup; the micro-motion assembly is arranged in the large cup, and the micro-motion assembly comprises a small cup, a micro-switch and a soft magnet. The structure and the connection mode of the big cup and the small cup are improved; the limiting sheet of the small cup acts on the hole site in the large cup to move; the problem of slot deviation of an old magnetic steel sensor is avoided; the stability of the magnetic steel sensor is improved, the microswitch is added, the soft magnetic bearing effect is achieved, the defect that soft magnetism falls off is overcome, the contact in the microswitch is affected by the soft magnetism and the magnet, the microswitch is used for switching between two modes, and the automatic control effect is achieved.

Description

technical field [0001] The invention relates to the field of temperature controllers, in particular to a magnetic steel sensor. Background technique [0002] The magnetic steel sensor is a temperature controller, which is mostly used in the rice cooker. It belongs to a mechanical device that can automatically power off the rice cooker. For the current magnetic steel sensor, in terms of structural stability, the large cup and the small cup The multiple contact frictions will damage its parts and reduce the service life. Secondly, the use and installation of some magnetic steel sensors are more complicated. Contents of the invention [0003] The present invention solves the above mentioned problems by providing a magnetic steel sensor. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] A magnetic steel sensor, comprising: [0006] Big cup, the big cup has holes up and down, the big cup is provided with a circu...
