Abstract

The utility model discloses a multi-voltage flexible heating device, consisting of a controller, two couplers and a heating felt. The multi-voltage flexible heating device is characterized in that the heating felt is composed of three layers of spiral lines and two couplers, wherein, the three layers of spiral lines include an inner layer of heating wires, a middle layer of temperature-sensing wires and an outer layer of heating wires; the inner layer of heating wires and the temperature-sensing wires are connected with the right coupler, the outer layer of heating wires and the temperature-sensing wires are connected with the left coupler; the couplers are connected with the controller. The utility model overcomes the disadvantages of single voltage, narrow application range and low security performance of the general heating felt and is applicable to the occasions with 110V or 220V for heating.

Description

The flexible heat generation device of multivoltage

Technical field

The utility model relates to the daily life field, and a kind of specifically voltage that is used for is that the place of 220V and 110V is used for the heat generation device of heating service.

Background technology

Present common heat generation device working voltage is single, the scope of application is narrower, and cost height, security performance are low.

Summary of the invention

Present heat generation device working voltage is single, the scope of application is narrower in order to solve for the utility model, and cost height, the problem that security performance is low provide a kind of electric blanket that can be used for heating service in the place of 220V and 110V.

The technical solution adopted in the utility model is, the flexible heat generation device of a kind of multivoltage, constitute by a controller, two couplers and the blanket body that generates heat, its special character is: heating blanket body is made up of three helical layer lines and two couplers, three helical layer lines are made up of internal layer heating wire, intermediate layer temperature-sensitive silk, outer heating wire, the right coupler of internal layer heating wire and temperature-sensitive wire connection, outer heating wire and temperature-sensitive wire connection left side coupler, coupler is connected with controller.

During use, at first select working voltage, when voltage was 110V, it is firm that controller and left coupler are pegged graft, and opens the switch of controller, selects suitable gear heating, forbids catching at this moment touching the contact pin of right coupler; When voltage was 220V, it is firm that controller and right coupler are pegged graft, and opens the switch of controller, selects suitable gear heating, forbids catching at this moment touching the contact pin of left coupler.

Technique effect of the present utility model is, adopts such scheme can realize that a kind of simple to operate, performance safety, multivoltage use, cheap heat generation device.

Description of drawings

Fig. 1 is a structural front view of the present utility model, and as Figure of abstract.

In the drawings, 1 heating blanket body, 2 three helical layer temperature control lines, 3 outer heating wires, 4 intermediate layer temperature-sensitive silks, 5 internal layer heating wires, 6 left couplers, 7 controllers, 8 right couplers.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As shown in the figure, the flexible heat generation device of a kind of multivoltage, constitute by a controller 7, two couplers and heating blanket body 1, its special character is: heating blanket body 1 is made up of three helical layer lines 2 and two couplers, three helical layer lines 2 are made up of internal layer heating wire 5, intermediate layer temperature-sensitive silk 4, outer heating wire 3, internal layer heating wire 5 and temperature-sensitive silk 4 connect right coupler 8, and outer heating wire 3 and temperature-sensitive silk 4 connect left coupler 6, and coupler is connected with controller 7.

During use, at first select working voltage, when voltage was 110V, it is firm that controller 7 and left coupler 6 are pegged graft, and opens the switch of controller 7, selects suitable gear heating, forbids catching at this moment touching the contact pin of right coupler 8; When voltage was 220V, it is firm that controller 7 and right coupler 8 are pegged graft, and opens the switch of controller 7, selects suitable gear heating, forbids catching at this moment touching the contact pin of left coupler 6.
