Abstract
The invention discloses a self-temperature-controlling heater which comprises a temperature sensor, an integrated control circuit, a heating element and a first metal casing. The temperature sensor is connected with the integrated control circuit, two ends of the heating elements are both connected with the integrated control circuit which is externally connected with a power source, the temperature sensor, the integrated control circuit and the heater are integrated in the first metal casing, and first insulating fillers are filled in gaps of the first metal casing. The self-temperature-controlling heater has the advantages of being reasonable in structure, convenient to use, high in accuracy, capable of achieving the aim of self temperature controlling with no additional control circuit and capable of reducing development cost of an applicant.
Description
Technical field
The present invention relates to the heater control fields such as a kind of automobile, medical treatment, chemical industry, is a kind of Automatic Control Temperature Heater specifically.
Background technology
Heater often can be used at automobile, medical treatment, chemical field, but existing heater exists following defect: function singleness, only play the function of heating, and can not realize temperature simultaneously and control; If need to realize temperature, control, just need to additionally join control circuit, and application circuit is complicated; Extra control circuit need separately take up space; As use the words temperature-controlled precision of bimetal release low.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the object of this invention is to provide a kind of rational in infrastructure, easy to use, can realize Automatic Control Temperature Heater temperature automatically controlled and that temperature-controlled precision is high.
Technical scheme: in order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of Automatic Control Temperature Heater, comprise temperature sensor, integral control circuit, heating element, the first metal-back, temperature sensor is connected with integral control circuit, the two ends of heating element are all connected with integral control circuit, integral control circuit external power supply, described temperature sensor, integral control circuit, heater are integrated in the first metal-back, in the gap of the first metal-back, are all filled with the first insulation filler.
Operation principle of the present invention is: apply after external power source, integral control circuit work, heating circuit conducting, start heating, integral control circuit is collected simultaneously, the change in resistance signal of analysis temperature transducer, when temperature is elevated to certain design temperature, temperature sensor resistance is reduced to setting resistance, integral control circuit disconnects heating circuit, stop heating, temperature starts to decline, with temperature, decline, temperature sensor resistance is elevated to set point, integral control circuit is connected heating circuit, so circulation, back and forth, the temperature constant of whole heating element is controlled to certain set point.
As improvement of the present invention, in described the first metal-back, also comprise the second metal-back, described temperature sensor and integral control circuit are located in the second metal-back, in the gap of the second metal-back, are filled with the second insulation filler.
As a further improvement on the present invention, described integral control circuit is temp control switch circuit.
In order to improve insulation effect, described the first insulation filler is epoxy resin.Described the second insulation filler is fire clay.
Beneficial effect: compared with prior art, advantage of the present invention is: rational in infrastructure, easy to use, precision is high, and separately do not add control circuit and just can directly reach temp auto-controlled object; Can also reduce application person's development cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, a kind of Automatic Control Temperature Heater, comprises temperature sensor 1, integral control circuit 2, heating element 4, the first metal-back 6, the second metal-back 5, and wherein heating element 4 is heating rod; Integral control circuit 2 is temp control switch circuit, and it has 5 pins, is respectively and connects positive source pin, connects power cathode pin, connects heating element pin, jointing temp passes this device pin, jointing temp passes this device pin.
The positive source pin that connects on integral control circuit 2 is all connected on power supply with the pin that connects power cathode, the pin that the two ends of heating rod 4 connect positive source pin with on integral control circuit 2 respectively, connect heating element 4 is connected, temperature sensor 1 is all located in the second metal-back 5 after being connected with the pin of two jointing temp transducers on integral control circuit 2, is filled with the second insulation filler 7 in the gap of the second metal-back 5; The second metal-back 5 and heating element 4 are integrated in the first metal-back 6, in the gap of the first metal-back 6, are all filled with the first insulation filler 3;
The first insulation filler 3 adopts, and what be that epoxy resin, the second insulation filler 7 adopt is fire clay.
During use, apply after external power source, integral control circuit 2 is started working, then heating circuit conducting, heating rod starts heating, integral control circuit 2 is collected simultaneously, the change in resistance signal of analysis temperature transducer 1, when temperature is elevated to certain design temperature, temperature sensor 1 resistance is reduced to setting resistance, integral control circuit 2 disconnects heating circuit, stop heating, temperature starts to decline, with temperature, decline, temperature sensor 1 resistance is elevated to set point, integral control circuit 2 is connected heating circuit, so circulation, back and forth, the temperature constant of whole heating rod is controlled to certain set point.The present invention just can realize automatic control temperature control like this.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
