Detailed description of the invention
In conjunction with accompanying drawing, the utility model is described in further detail, sees accompanying drawing 1-5.
nullAs Figure 1-5，This utility model one insulation cushion，Including cushion body 10，Described cushion body 10 is respectively arranged at two ends with for placing the warming insert port of hands 33，The insert port 33 at described two ends communicates，Attemperating unit 20 and electro-heat equipment 30 it is provided with in described cushion body 10，Described attemperating unit 20 electrically connects with electro-heat equipment 30，Described attemperating unit 20 one end is provided with wire 31，Described wire 31 one end is provided with a joint 32，When joint 32 is connected with external power source，Now charging starts，First pass through electro-heat equipment 30 and carry out the most heating up，After reaching certain temperature，Now by the overtemperature protection attemperating unit 20 being arranged in cushion，Efficiently control electro-heat equipment 30 to generate heat，Avoid temperature too high，Thus can reach steady temperature keep constant for cushion heating constantly，Avoid scalding and being beneficial to insulation，Use and also compare safety.
Wherein, described attemperating unit is provided with temperature control circuit, described temperature control circuit includes relay J, PNP triode Q1, NPN audion Q2, critesistor R, UA741 amplifier W, coil one end of relay J is connected with the emitter stage of PNP triode Q1 and the end of oppisite phase of UA741 amplifier W respectively, and the colelctor electrode of NPN audion Q2 is connected with the coil other end of relay J；The colelctor electrode of PNP triode Q1 is connected with the base stage of NPN audion Q2, and the base stage of PNP triode Q1 is connected with the outfan of UA741 amplifier W；nullIt is connected between in-phase end and the end of oppisite phase of UA741 amplifier W and has critesistor R，When circuit in use when，In circuit, the voltage of critesistor R and the voltage of another fixed resistance are compared by UA741 amplifier W，The resistance value of critesistor R is relatively low under normal circumstances，The magnitude of voltage of its load is also the most relatively low，But when external temperature is too high，The resistance of critesistor R can increase rapidly，The magnitude of voltage of its load is the biggest，When the voltage of critesistor R is more than certain numerical value，UA741 amplifier W will export high level and activate PNP triode Q1 and NPN audion Q2，When NPN audion Q2 is activated，The circuit at the coil place of relay also turns on，The normally closed relay J being now connected with operating circuit disconnects，Electro-heat equipment 30 stops heating，Avoid that temperature is too high to be damaged hand,When temperature is less than steady temperature when，Now electro-heat equipment 30 starts again heating，Temperature-resistant with ensure inside cushion.
Concrete, described joint 32 is USB joint, and USB joint is universal joint, can improve its practicality with multiple power sources matching connection.
In the present embodiment, described cushion body 10 is provided with the pocket 40 for holding movable power supply, and described pocket 40 is provided with slide fastener 41, when the article such as portable power source and data wire put into by pocket 40 when, closed by the slide fastener 41 being arranged on pocket 40, be convenient for carrying whole cushion and article.
In the present embodiment, described cushion body 10 is cylindrical, and being arranged to cylinder is material-saving, thus cost-effective, naturally it is also possible to is set to square or other shapes etc., thus improves individual demand.
Finally should be noted that; above example is only in order to illustrate the technical solution of the utility model; rather than the restriction to this utility model protection domain; although having made to explain to this utility model with reference to preferred embodiment; it will be understood by those within the art that; the technical solution of the utility model can be modified or equivalent, without deviating from the spirit and scope of technical solutions of the utility model.
