Own temperature and the heat of turn-on current are known, to drive the on-off action for electrically connecting switch module, to realize that control electric appliance is set
The purpose of stand-by power source, in addition to (application scenarios are such as the application scenarios of conventional temperature control device：Warehouse, storage room, fruit and vegetable greenhouses etc. are prevented
Low temperature frost is placed in the control box for being equipped with the present invention in the anti-low temperature frost environment of warehouse, storage room, fruit and vegetable greenhouses etc.,
Power supply is accessed, when environment temperature drops to the start-up temperature that the present invention is set, power supply is connected, all at this time to be connect with this power supply
Equipment such as heating furnace, terrestrial heat pump, Hot-air fan all enter work, the electric current that flows through of the present invention is own temperature Sensitive Apparatus at this time
Heating, until when temperature rise is to the break-off signal of the invention set, power supply disconnects, and so recycles, temperature is allowed to be maintained at setting
In the range of, will not freeze frost) can be except use, also adding remote control function (refers to remotely：The present invention does not have to peace
It, only need to be with being in a regional environment in the electrical equipment body controlled, control circuit is connected i.e. with electrical equipment
Can), that is to say, that closure and the disconnection of circuit are realized by the heat that electric current generates, it need not be real by awareness apparatus temperature
The now effect of long-range current temperature control.
It should be noted that being equipped with limit iron plate 50 below fixed touching plate 7, limit iron plate 50 is equipped with low temperature limit and adjusts
The top of screw 51, low temperature limit adjusting screw 51 contacts at the upper reed plate 4 with current-limiting resistance and the lower reed with current-limiting resistance
5 Laser Welding weld.Using such structure setting, when high temperature, limit iron plate 50 is produced with the upper reed plate 4 with current-limiting resistance
Life is upwardly-deformed, and the upper reed plate 4 with current-limiting resistance is upwardly-deformed to be caused between the lower reed 5 with current-limiting resistance and fixed touching plate 7
Circuit disconnects, and the upwardly-deformed upper reed plate 4 caused with current-limiting resistance of limit iron plate 50 will not again be resetted in low temperature (to be limited
The upper reed plate 4 with current-limiting resistance deforms downwards when low temperature), circuit unicom again is prevented, effectively avoids equipment in low temperature environment
Turn on automatically power supply causes danger, and in practical application, low temperature limits adjusting screw 51 using adjusting screw by the way of rotation adjusting
Height, injected in screw fixing glue recess 503 by fixing glue again after regulating and realize that low temperature limits determining for adjusting screw 51
Position.
The present invention's electrically connects switch module collection temperature sensing function, temp regulating function, electric current heating function, switch motion work(
Can (tradition electrically connects switch module and there was only temp regulating function and switch motion function), of the invention electrically connects switch
Upper reed plate 4 of the component with current-limiting resistance is made with temperature-sensitive material, and dexterously adds electric current incoming end and current-limiting resistance
Structure, the current-limiting resistance structure of lower reed and the laser welding of upper and lower reed and the design of heat transfer structure, to make to electrically connect

Degree control, electric current add environment temperature complex controll, can also carry out remote control except equipment, compare conventional temperature control device
For, temperature sensing device and transmission device are saved, saves cost, and overall structure installation is easier, is saved artificial.
It should be noted that traditional upper reed plate is the advantages of using electric resistance welding with lower reed：Welding machine is small and exquisite, price
Cheaply, it safeguards simple.The shortcomings that traditional upper reed plate uses electric resistance welding with lower reed is：1) slow (Welder of speed of welding
Sequence includes putting, electrode closure, welding, electrode opening, taking), electrode is contact type welding with product, each solder joint will be completed
A whole set of action, each solder joint at least want could complete for 1 second；2) consistency of solder joint is of poor quality, and the characteristic of electric resistance welding exists
In：The resistance that welded article body bond pad locations contact with each other is that fever loads, and welded article body phase mutual connection is symmetrically pressed by two electrodes
Discharge high current in short-term after touch, keep contact point exothermic melting and adhesion, during electric resistance welding, top electrode and lower electrode and
The welded article being accessed can all generate resistance, and the welding circuit of series circuit is formed with the purpose resistance to be welded, and weld work(
Rate will be distributed on the resistance other than solder joint, cause between electrode and soldered object sparking, adhesion, purpose pad again rosin joint,
Dry joint has several factors and randomness because generating the resistance other than purpose pad, and can only control to prevent completely, so electric
The solder joint of welding resistance only welds above, and the shape, size, degree of adhesion of solder joint cannot be required to have very high consistency.The present invention adopts
It is welded with Laser Welding, compares traditional electric resistance welding, the advantage is that：1) solder joint speed of welding is fast, and Laser Welding welding is
Contactless light irradiation welding (welding sequence includes putting, welding, taking) a set of action can complete all welderings of batch
Spot welding, puts：It is merely placed in specified larger (such as diameter 20cm) circular scope, as long as all pads are in this circular scope
It is interior, it can once put a batch and want soldering part；Welding：Whole solder joints are once soldered within the scope of this, as long as several milliseconds of each solder joint,
Our production efficiency practice result is 10 times of electric resistance welding or more；2) Laser Welding welding is contactless illumination weldering
Connect, the consistent property amount of solder joint only by：1. light absorptive (identical material identical surface conformance is high) 2. spot sizes of welded article,
The shape of light extraction effect, light extraction time (welding parameter is controlled by laser machine completely, is not influenced by welding circuit, consistency height) solder joint
Shape, size, degree of adhesion are fully controllable, and consistency is high.
