Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, provide after a kind of power-off just can not automatically reset, the hand-reset adjustable temperature controller of safe and long service life.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of hand-reset adjustable temperature controller, comprise top board, on top board, be provided with upper terminal, lower terminal and bimetal leaf, lower terminal is provided with fixed contact, on bimetal leaf, be provided with moving contact, upper terminal and moving contact are electrically connected, and an electro-heat equipment that makes upper terminal and lower terminal disconnection or be communicated with is set between upper terminal and lower terminal.
In technique scheme, upper terminal, lower terminal and bimetal leaf are connected in series and are fixed on top board by rivet from top to bottom successively, between top board, upper terminal, lower terminal and bimetal leaf are adjacent, are provided with insulating part.
In technique scheme, the insulating part between top board, upper terminal and lower terminal is pottery or mica sheet or bakelite.
In technique scheme, the insulating part between lower terminal and bimetal leaf is pottery.
In technique scheme, electro-heat equipment comprises metal buckle and the PTC thermistor of the effect of matching, and metal buckle connects upper terminal, and PTC thermistor is arranged in lower terminal.
In technique scheme, between bimetal leaf and moving contact, by insulating part, be connected.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of hand-reset adjustable temperature controller, comprise top board 1, on one end of top board 1, by rivet 14, be connected in series successively upper terminal 2, lower terminal 3 and bimetal leaf 4, between top board 1 and upper terminal 2, be provided with ceramic block 6, between upper terminal 2 and lower terminal 3, be provided with mica sheet 7, between lower terminal 3 and bimetal leaf 4, be provided with ceramic block 6, this ceramic block 6 is all to guarantee upper terminal 2 as insulating part with mica sheet 7, contact energising between lower terminal 3 and bimetal leaf 4 between contact, there are not other contacts, guarantee the stability of this temperature controller.One end of lower terminal 3 is provided with fixed contact 9, and the contact of fixed contact 9 up.Bimetal leaf 4 is to the direction horizontal-extending that is provided with fixed contact 9, and the end extending is provided with the earthenware 12 erecting, the top cross of this earthenware 12 arranges lower shell fragment 10, lower shell fragment 10 extend transverse to fixed contact 9 directly over, the extending end of lower shell fragment 10 is provided with moving contact 8, and this lower shell fragment 10 is electrically connected with moving contact 8.Upper terminal 2 joins with lower shell fragment 10 by upper shell fragment 11, and lower shell fragment 10 is electrically connected with upper shell fragment 11.The other end of top board 1 is provided with the regulating shaft 13 of a rotatable adjusting upper-lower position, these regulating shaft 13 bottom insulation, and the bottom of regulating shaft 13 is leaning and is going up shell fragment 11.Between upper terminal 2 and lower terminal 3, electro-heat equipment 5 is set, this electro-heat equipment 5 comprises metal buckle 51 and PTC thermistor 52, one end of metal buckle 51 and upper terminal 2 are electrically connected, be folded between the ceramic block 6 and upper terminal 2 between top board 1 and upper terminal 2, the other end of metal buckle 51 is arranged on above PTC thermistor 52, PTC thermistor 52 is arranged on one end of lower terminal 3, and this metal buckle 51 can make upper terminal 2 disconnect or be communicated with lower terminal 3 with PTC thermistor 52.
Preferably, the insulating part between top board 1, upper terminal 2 and lower terminal 3 is pottery or mica sheet 7 or bakelite.And insulating part between lower terminal 3 and bimetal leaf 4 is pottery, as the transmission of heat.
Operation principle of the present utility model: under normal connection status, metal buckle 51 and PTC thermistor 52 closed communicatings of electro-heat equipment 5, make upper terminal 2 be communicated with lower terminal 3; In addition, moving contact 8 is also communicated with fixed contact 9, is also that upper terminal 2 is communicated with lower terminal 3, and upper terminal 2 just exists two ends connected state with lower terminal 3.In the working equipment at this hand-reset adjustable temperature controller place, when generation abnormal conditions cause temperature constantly to raise, after the temperature that bimetal leaf 4 senses acquires a certain degree, the free end of bimetal leaf 4 will occur bending and deformation, thereby the earthenware 12 that links successively, lower shell fragment 10 and moving contact 8, make to disconnect at moving contact 8 and fixed contact 9, lower terminal 3 disconnects with one end of upper terminal 2.The other end that upper terminal 2 is communicated with lower terminal 3, the two ends that are electro-heat equipment 5 produce voltage, the temperature of PTC thermistor 52 is raise, the resistance of PTC thermistor 52 also can raise, then the temperature of PTC thermistor 52 improves all the more, distribute heat constantly, and this heat is delivered on bimetal leaf 4 by the ceramic block 6 between lower terminal 3 and bimetal leaf 4, the temperature of bimetal leaf 4 is maintained, allow moving contact 8 and fixed contact 9 remain open, due to temperature moment raising under high voltage of PTC thermistor 52, its resistance also improve by moment; After the resistance of PTC thermistor 52 rises to a certain degree, upper terminal 2 is also equivalent to disconnect with lower terminal 3, and equipment quits work.Must manually metal buckle 51 and PTC thermistor 52 be disconnected, this controller just recovers automatically reset function.By rotation regulating shaft 13, regulating shaft 13 is moved down, thereby pressing, go up shell fragment 11, upper shell fragment 11 is subject to acting on lower shell fragment 10 after downward pressure, lower shell fragment 10 is also moved down with moving contact 8, for making moving contact 8 keep a relative suitable gap with fixed contact 9, the suitable contact in the time of guaranteeing work is with easily separated.The utility model has guaranteed can not waste electricity, has extended the life-span of this controller, the more important thing is the existence of potential safety hazards such as avoiding breaking out of fire or blast.
Above embodiment is just explanation rather than restriction the utility model, and the equivalence of doing according to the method described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
