Abstract

The utility model provides a multi-voltage flexible heating appliance which consists of a controller, two couplers and a heating blanket body, and is characterized in that the heating blanket body consists of three layers of helical lines and the two couplers, the three layers of helical lines consist of an inner-layer heating wire, an intermediate-layer temperature sensing wire, and an outer-layer heating wire, the inner-layer heating wire and the temperature sensing wire are connected with the right coupler, the outer-layer heating wire and the temperature sensing wire are connected with the left coupler, and the couplers are connected with the controller. The multi-voltage flexible heating appliance overcomes the problems of single voltage, narrow application range and poor safety performance of a common electric blanket, and is applicable to places with 110V and 220V voltage for heating and dispelling cold.

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, right coupler is connected with controller when using the internal layer silk, and left side coupler is connected with controller when using outer.

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, outer heating wire 3 and temperature-sensitive silk 4 connect left coupler 6, right coupler 8 is connected with controller 7 when using the internal layer silk, and left side coupler 6 is connected with controller 7 when using outer.

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.
