Abstract
The utility model relates to an electric heating device. The device comprises a power supply, an electric heating wire, a PTC core block matched with the electric heating wire and other elements. The device solves the disadvantages that the existing electric heating products having complex internal structure are not suitable for small products, etc. The utility model has the advantages of simple structure, reasonable structure, convenient use, etc.
Description
The utility model relates to a kind of electric calorifie installation.
The electric heating structure of inside such as at present commercially available electric heating products such as electric blanket is complicated, is unsuitable for using on small sized product.
The purpose of this utility model is to provide a kind of electric calorifie installation simple in structure to overcome the deficiency that prior art exists.
Overall structure of the present utility model is:
A kind of electric calorifie installation, the heating wire (1) that it comprises power supply (3), connect with power supply (3), thermostat, and mains switch.
Other architectural features of the present utility model also have:
Thermostat and mains switch are PTC pellet (2).
Accompanying drawing of the present utility model has:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a circuit diagram of the present utility model.
Accompanying drawing has provided embodiment of the present utility model, and the present embodiment will be explained in conjunction with the accompanying drawings:
Present embodiment belongs to the application of this device on gloves, these gloves are mainly used in the open-air open-air driver who drives motor vehicles and use, power supply (3) adopts the vehicle its own power source, and heating wire is flush-mounted in the glove interlayer, and heating wire (1) two ends are connected in series with PTC pellet (2) and power supply (3), because PTC pellet (2) self has the characteristic of constant temperature heating, so when temperature was raised to main rating number, the PTC internal resistance increased, current limit changes, make temperature near constant, play the temperature control effect.
The obtained technological progress of the utility model is that this apparatus structure is simple, reasonable, easy to use, can be widely used in various civilian small heater articles for use.
Claims (2)
1, a kind of electric calorifie installation is characterized in that heating wire (1) that it comprises power supply (3), connects with power supply (3), thermostat, and mains switch.
2, electric calorifie installation according to claim 1 is characterized in that described thermostat and mains switch are PTC pellet (2).
