Micro temperature-sensitive magnetic control switch

Abstract

The invention discloses a micro temperature-sensitive magnetic control switch which comprises an upper shell and a rotary sliding sleeve. wherein the upper shell is internally provided with a soft magnet which is made of temperature-sensitive ferrite materials; a hard magnet is arranged below the soft magnet; a spring is arranged between the soft magnet and the hard magnet; the upper end of the spring is connected with the soft magnet; the lower end of the spring is connected with the hard magnet; a heat conduction outer shell tightly contacts above the soft magnet; a connecting rod stretches into the inside of the upper shell from the bottom of the upper shell and is fixedly connected with the hard magnet; the rotary sliding sleeve is internally provided with an electric conducting sheet; an electric conducting elastic sheet is arranged dead below the electric conducting sheet in a tight matched mode; the electric conducting sheet and the electric conducting elastic sheet are respectively connected with a wiring terminal; the connecting rod stretches into the rotary sliding sleeve and is tightly matched with the electric conducting elastic sheet; when the connecting rod leaves away the electric conducting elastic sheet, the electric conducting sheet contacts with a contact point on the electric conducting elastic sheet, thus the whole circuit is conducted; and when the connecting rod moves downward and pushes the electric conducting elastic sheet to move downward, and the electric conducting sheet is separated from the contact point on the electric conducting elastic sheet, thus the whole circuit is disconnected. According to the invention, the temperature control sensitivity is high, the performance is stable, and the temperature control accuracy is high.

Description

technical field [0001] The invention relates to a temperature controller, more specifically, to a miniature temperature-sensitive magnetic control switch. Background technique [0002] At present, the temperature controller used in the market is a bimetal structure. Due to the high processing accuracy requirements of bimetal materials and harsh heat treatment conditions, the pass rate of this product is low in the production process. Bimetal sheets mainly rely on imports, and the price is high. Poor precision, poor corrosion resistance, easy to rust and lead to failure. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a miniature temperature-sensitive magnetic control switch with high temperature control sensitivity, stable performance and high temperature control precision. [0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: [0005] A miniatu...
