Fig. 2 is the structural representation of electric calorifie installation among the utility model embodiment one;
Fig. 3 is the schematic diagram among the utility model embodiment two.
Embodiment:
See Fig. 1,2, the health product main body 1 in the present embodiment can be any one in many electric heating health products such as electric blanket, electric heating waistband, electrically heated glove.Usually the main body 1 of this health product adopts fabric to make, and its inside is provided with electric calorifie installation 3, and the electric calorifie installation 3 generation heat of working under "on" position acts on the human body after seeing through fabric, to human body heat, health-care efficacy.
Described heating wire 32 comprises two groups at least, and this heating wire 32 is by a jockey 33 parallel connections.Also be connected with a temperature signal line 34 on the described jockey 33.Be specially: described jockey 33 is provided with four terminals, wherein two terminals are power supply terminal 331,332, two other terminal is a signal terminal 333,334, the two ends of described heating wire 32 are connected on two power supply terminals 331,332, and the two ends of described holding wire 34 are connected on two signal terminals 333,334.Holding wire 34 is the temperature monitoring holding wire, and it can be returned the Temperature Feedback of electric heating products immediately, if temperature is too high, then controls heating wire 32 and quits work, and human body is damaged preventing.
Described main body 1 is provided with a socket 30 that is communicated with jockey 33, and low voltage power supply device 31 is heating wire 32 power supplies by socket 30, and passes through the signal control circuit of holding wire 34 feedbacks.
