Abstract
The utility model relates to a constant temperature regulator for cold-proof garment, comprising a component mounting box, an electrothermal element, a sensing element and low-voltage power supply, wherein, the sensing element adopts a thermistor R<1> with negative temperature coefficient as a base bias self-regulating point of compound transistors BG<1> and BG<2>, and the output control relay J of the compound transistor BG<2> is communicated with the power supply loop of the electrothermal element. The utility model has simple and practical structure, can regulate automatically the temperature of the cold-proof garment according to the change of the temperature with less power consumption and strong applicability, and is especially used for workers wearing out of doors in winter.
Description
The utility model belongs to the parts of electric calorifie installation, is specifically related to a kind of the resisting cold with the thermostatic control parts of low-voltage electroheating clothes.
The low-voltage electroheating clothes are because its dress is convenient, and power consumption is few, and environmental suitability is strong, is subjected to the welcome outwork cold season personnel.In present commercially available electric heating clothes and the known technology, the temperature of electric heating clothes control, a kind of is that the circuit of replacement by thermo electric material or wiring changes and regulates temperature, as Chinese patent CN87211387U, CN2030813U.Another kind is to rely on ceramic semiconductors (PTC) (positive temperature coefficient) thermal resistor, and energising back PTC self-heating and heat radiation come temperature automatically controlled, insulation, and it need install heater element in the whole multi-section of clothes position, as CN2098816U.More general is to adopt manually switch or adopt time constant circuit to control heat time heating time.As CN2083375U.Exist temperature control device cost of manufacture height in the known technology, can not be automatically start heating and adjustment heat time heating time with the variation of environment temperature effectively.
The purpose of this utility model is to provide a kind of device that can control the electric heating clothes temperature with variation of ambient temperature.
The utility model is taked following technical scheme.
The insulated cold wear adjuster includes element mounting box, heating, sensing element, low-tension supply, and sensing element adopts the thermistor with negative temperature coefficient to insert compound transistor group BG
1, BG
2The base bias loop, as the preposition utmost point BG of compound transistor
1Base bias adjust some BG automatically
2Output control relay J connect the electric power loop of heating, driving switch K can change and connect R
1Or R
2, adjust BG
1Base voltage.
The utility model is compared prior art, have simple for production, with low cost, advantage such as result of use is good.
Below in conjunction with accompanying drawing the utility model is further described in detail.
Fig. 1 is an insulated cold wear constant temperature regulator electrical schematic diagram.
Fig. 2 is the outline drawing of insulated cold wear constant temperature regulator.
Among the figure, R
1, R
2Be bias-adjusted resistance, R
TBeing thermistor, 1 is power outlet 2, for the sensing element wiring, and 3 are the load tie.
In the present embodiment, sensing element places resisting cold clothes inboard, and it connects the electric power loop of heater element automatically with the environment temperature of body surface, and driving switch turns to R
1Or R
2Thermistor R then
TThe environment induction temperature also will change.This product export is adjusted temperature, when the I shelves, and R
TConducting to 30 ℃ (ending) when the body surface environment temperature of induction is 20 ℃.
Body surface environment temperature working range is 25 ℃-30 ℃ when the II shelves.
Accompanying drawing 1 is as Figure of abstract.
