Abstract
A kind of thermostat, comprise insulating part and be arranged on the bimetal leaf below insulating part, be provided with metal gasket between insulating part and bimetal leaf, one end of bimetal leaf is fixedly installed on the below of insulating part by metal gasket.The utility model is by the improvement of said structure, when the diameter D of insulating part and the length of bimetal leaf fix, diameter A due to metal gasket is less than the diameter D of insulating part, and one end of bimetal leaf is fixedly installed on the below of insulating part by metal gasket, therefore the bending length of this structure bimetal leaf will be grown compared with the bending length of prior art bimetal leaf, increase the rate of curving and the deformation amplitude of bimetal leaf widely, effectively improve the temperature control precision of thermostat, make the serviceability of thermostat more reliable.The features such as it has simple and reasonable, dependable performance, and low cost of manufacture is easily produced, easy realization, practical.
Description
Technical field
The utility model relates to a kind of thermostat.
Background technology
The operation principle of thermostat is bent upwards after being heated by bimetal leaf, promotes shrapnel contact and disconnect, thus play temperature control function, and namely the temperature-controlled precision of thermostat is determined by the rate of curving of bimetal leaf and deformation amplitude.
The thermostat of prior art, as shown in Figure 1, the end of bimetal leaf 1 ' is pressed on the below of insulating part 2 ', wherein the diameter D ' of insulating part 2 ' is generally 12.5mm, because the diameter D ' of insulating part 2 ' and the length of bimetal leaf 1 ' are fixed, during the end heated bending of bimetal leaf 1 ', diameter D ' the contact length of its rate of curving and deformation amplitude and insulating part 2 ' is larger, the rate of curving and the deformation amplitude of bimetal leaf 1 ' are less, bimetal leaf 1 ' needs the long period could accumulate the distortion of enough heats, promotion shrapnel contact disconnects, cause bimetal leaf 1 ' thermal flexure sensitivity not enough, spring is clumsy, sensitive not, there is potential safety hazard, the user demand of user can not be met.Therefore, further improvement is necessary.
Utility model content
The purpose of this utility model aims to provide a kind of simple and reasonable, dependable performance, and low cost of manufacture, easily produces, and a kind of thermostat easily realized, to overcome weak point of the prior art.
By a kind of thermostat that this object designs, comprise insulating part and be arranged on the bimetal leaf below insulating part, it is characterized in that: be provided with metal gasket between insulating part and bimetal leaf, one end of bimetal leaf is fixedly installed on the below of insulating part by metal gasket.
Described insulating part is cylindrical, and metal gasket is circular, and the two concentric cooperatively interacts connection, and wherein the diameter A of metal gasket is less than the diameter D of insulating part.
The diameter A of described metal gasket is 6mm-10mm, and the diameter D of insulating part is 10mm-14mm.
Described metal gasket is fixedly installed on the below of insulating part by binding, welding or securing member.
One end of described bimetal leaf is fixedly installed on the below of metal gasket by binding, welding or securing member.
Described thermostat also comprises shell fragment, and one end of shell fragment is connected by the other end of insulation porcelain rice and bimetal leaf.
The other end of described shell fragment is provided with moving contact, and the corresponding moving contact of insulating part is provided with fixed touching plate, and the outer end of fixed touching plate is provided with determines contact and be connected with moving contact or disconnect.
The utility model is by the improvement of said structure, metal gasket is provided with between insulating part and bimetal leaf, one end of bimetal leaf is fixedly installed on the below of insulating part by metal gasket, wherein insulating part is cylindrical, metal gasket is circular, the two concentric cooperatively interacts fixing, and the diameter A of metal gasket is less than the diameter D of insulating part, when the diameter D of insulating part and the length of bimetal leaf fix, diameter A due to metal gasket is less than the diameter D of insulating part, and one end of bimetal leaf is fixedly installed on the below of insulating part by metal gasket, therefore the bending length of this structure bimetal leaf will be grown compared with the bending length of prior art bimetal leaf, increase the rate of curving and the deformation amplitude of bimetal leaf widely, effectively improve the temperature control precision of thermostat, make the serviceability of thermostat more reliable.The features such as it has simple and reasonable, dependable performance, and low cost of manufacture is easily produced, easy realization, practical.
