The control circuit board set between the electric heating layer and the battery has temperature probe comprising IC, great power switching transistor and thermistor. The present invention may be produced into waist protecting belt, knee pad or stomach protecting belt. The present invention has the advantages of automatic temperature control, convenient use and safety.
Description
One, technical field
The present invention relates to medical health appliance, be specifically related to the warm watch box of a kind of convenient and safe electric heating.
Two, background technology
Traditional treatment rheumatic arthritis, cold syndrome of the stomach, lumbago method be with hot water bag stick, cupping or diathermy, and very effective, but because methods such as hot water bag, cupping, diathermy operation inconvenience, the people of use is fewer and feweri.At present, people more are ready to adopt the warm watch box treatment of electric heating rheumatic arthritis, cold syndrome of the stomach and lumbago, because the warm watch box of electric heating is simple and easy to do, curative effect is also good.The heater element of the warm watch box of early stage electric heating is to adopt heating wire, employing (PTC) ribbon heater arranged afterwards, as the disclosed technology of Chinese patent ZL96225167.4; Have and adopt carbon fibre heating plate, as the disclosed technology of Chinese patent ZL95115466.4.The defective of above-mentioned technology is to use fixed power source, can not on the other hand, be not easy to control temperature, fire hazardous in outdoor application.Chinese patent ZL 03219439.0 discloses a kind of rechargeable electric heating knee protector, mainly by the knee cap cover, heater, electric appliance control box is formed, knee cap cartridge clip interlayer is provided with carbon fiber heater, knee cap overlaps a side and is provided with a pocket, be provided with control device in the electric appliance control box in the pocket, can control temperature constant, can in a few minutes, reach the temperature that sets, be convenient to external power supply and battery charge, in order to thermotherapy diseases of knee joint, it is the at present more advanced warm watch box of a kind of electric heating, its weak point is that electric appliance control box is not intelligent, needs manual switchover, uses inconvenient, temperature can not realize automatic control, still has disaster hidden-trouble.
Three, summary of the invention
The warm watch box of electric heating that the purpose of this invention is to provide a kind of convenience, safety.
The warm watch box of electric heating that the present invention is convenient and safe; comprise surface material distribution layer, internal electrical thermosphere and rechargeable battery; be characterized in: the base material of described electrothermal layer is a soft plastic; exothermic material is the thin layer carbon film that silk-screen gets on; current-carrying part is the argentum powder of low-resistivity silk-screen; described rechargeable battery is solid-state lithium polymer battery; the built-in short-circuit protection circuit of this battery; between described electrothermal layer and the described battery control circuit board is set also, described control circuit board is made up of the temperature probe that central IC circuit, high-power switch tube and critesistor constitute.
In the such scheme, described electric heating warms up watch box, can be made into back belt, knee cap or stomach protecting belt.
Advantage of the present invention is: owing to adopt solid-state lithium polymer battery, built-in short-circuit protection circuit can cut off electric current output automatically when discharge current is excessive, even short circuit can not blasted and burn yet, can not produce fire; Control circuit board is made up of the temperature probe that central IC circuit, high-power switch tube and critesistor constitute, and it constitutes a real-time detection circuit, can cut off output automatically when finding circuit abnormality, closes high-power switch tube; Electrothermal layer is because diaphragm-operated base material adopts soft plastic, exothermic material is the thin layer carbon film that silk-screen gets on, current-carrying part is the argentum powder of low-resistivity silk-screen, this diaphragm can not be out of shape at normal adstante febre diaphragm, diaphragm meeting gross distortion during high temperature (above 120 ℃), argentum powder on the silk-screen and carbon film can be torn, if what tear is argentum powder, can cause open circuit, circuit can stop heating immediately, if what tear is the carbon film of certain branch road, the resistance of whole carbon film circuit can increase, heating power can descend, and temperature can not continue to raise, and avoids breaking out of fire.
Four, description of drawings
Described in detail below in conjunction with embodiment of the invention accompanying drawing:
Fig. 1 is a fundamental diagram of the present invention;
Fig. 2 is the structural representation of one embodiment of the invention.
Five, the specific embodiment
As shown in Figure 1, control circuit board is made up of the temperature probe that central IC circuit, high-power switch tube and critesistor constitute.System initialization comprises own internal initialization of central IC circuit and external circuit initialization, cut off the electrothermal layer power supply, the temperature probe signal is accepted in preparation, the IC of central authorities circuit begins collecting temperature, the method of comparison of taking repeatedly to sample improves reliability and stability, when the temperature that collects was lower than start-up temperature, central IC circuit was exported control signal immediately, drove high-power switch tube and provided power supply to electrothermal layer, simultaneously, the IC of central authorities circuit continues collecting temperature, and temperature continues to raise, when the temperature that collects is higher than the cut-out temperature, the IC of central authorities circuit is exported control signal immediately, close high-power switch tube, cut off the electrothermal layer power supply, electrothermal layer stops heating, temperature can continue to descend, arrive start-up temperature, so repeat work, realize temperature control.
Shown in Figure 2 is the structural representation of the warm watch box of electric heating that the present invention is convenient and safe when making back belt; the surface is bed of cloth 1, internal electrical thermosphere 2, rechargeable battery 3; the base material of electrothermal layer 2 is soft plastics; exothermic material is the thin layer carbon film that silk-screen gets on; current-carrying part is the argentum powder of low-resistivity silk-screen; rechargeable battery 3 is solid-state lithium polymer batteries; the built-in short-circuit protection circuit of this battery; between electrothermal layer 2 and the battery 3 control circuit board 4 is set also, control circuit board 4 is made up of the temperature probe 5 that central IC circuit, high-power switch tube and critesistor constitute.
Claims (4)
