Description
Technical field
The present invention relates to temperature controller, more particularly, relate to a kind of micro temperature-sensitive magnetic control switch.
Background technology
Existing market uses thermostat to be bimetallic sheet structure, because the requirement on machining accuracy of bimetallic material is high, heat-treat condition is harsher, therefore qualification rate is low in this process of producing product, the main dependence on import of bimetal leaf sheet material, price is high, temperature-controlled precision is poor, corrosion-resistant, easily get rusty and cause lost efficacy.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of temperature control is highly sensitive, stable performance, micro temperature-sensitive magnetic control switch that temperature-controlled precision is high.
In order to solve the problems of the technologies described above, present invention employs following technical scheme:
A kind of micro temperature-sensitive magnetic control switch, it comprises the rotation sliding sleeve below upper casing and upper casing; In described upper casing, be provided with the soft magnetism be made up of temperature-sensitive ferrite material and be provided with Hard Magnetic below soft magnetism, spring is provided with and this spring upper end connects soft magnetism and this lower spring end connects Hard Magnetic between described soft magnetism, Hard Magnetic, above described soft magnetism, close contact has thermal conductive shell, and a connecting rod is by stretch into bottom described upper casing in upper casing and to be connected and fixed with described Hard Magnetic; In described rotation sliding sleeve, be provided with conducting strip, be provided with friction tight electroconductive elastic sheet immediately below conducting strip, described conducting strip, electroconductive elastic sheet are connected with a splicing ear all respectively; Described connecting rod stretch into rotate in sliding sleeve and with described electroconductive elastic sheet tight fit, when connecting rod leaves electroconductive elastic sheet, contact on conducting strip and electroconductive elastic sheet and make whole circuit turn-on, push away electroconductive elastic sheet move downward when connecting rod moves downward, the contact separation on described conducting strip and electroconductive elastic sheet and whole circuit is disconnected.
Described connecting rod and Hard Magnetic are linked together by a snap ring.
The present invention is owing to have employed said structure, and thermostat of the present invention has good electrical contact with heating container, and thermal conductive shell has good thermo-contact with heating container.Work start time, soft magnetism produces the magnetic force of adhesive owing to having magnetic conductivity and Hard Magnetic, spring is compressed, and connecting rod leaves electroconductive elastic sheet, and conducting strip contacts with electroconductive elastic sheet, and now, whole circuit turn-on, heater element is started working.When soft magnetism is heated, when exceeding the design temperature that heating container uses, soft magnetism arrives operating point temperature (Curie point) and loses magnetic conductivity, lose attracting magnetic force, under the action of the spring, connecting rod and Hard Magnetic are moved downward, conducting strip is made to be separated with electroconductive elastic sheet and to cut off circuit, the heater element of heating container quits work, when temperature drops to a timing, soft magnetism recovers magnetic conductivity, adhesive rapid in Hard Magnetic, make conducting strip and electroconductive elastic sheet contact rapidly from and connect circuit, heater element is started working.Therefore temperature control of the present invention is highly sensitive, stable performance, temperature-controlled precision are high, in addition, according to the characteristic of soft magnetism, its temperature control scope is wide, is approximately-80 DEG C ~ 280 DEG C.
After the detailed description of reading embodiments of the present invention by reference to the accompanying drawings, the features and advantages of the invention will become clearly.
