Description

A kind of anti-naked light of hot-water bottle, anti-dry burning device

Technical field

The utility model is related to a kind of anti-naked light of hot-water bottle, anti-dry burning device.

Background technology

Hot-water bottle is mainly heated by heating wire to the liquid in bag, so as to play a part of heating, often at present The electric hot-water bag seen generally comprises the sealing bag that an internal layer is made with PVC outer layers of PVC composite material-feedings, and bag is provided with electricity Heated filament (or heat-generating pipe), heating wire (or heat-generating pipe) is electrically connected with the electrical socket positioned at hot-water bottle surface, after switching on power, electric heating Silk (or heat-generating pipe), electrical socket and power supply built-up circuit are powered, and heating wire (or heat-generating pipe) is to the liquid heating in bag, with heating The increase of time, originally flat bag expands and heaved under liquid volume and steam constantly expansion, and is reached by temperature controller To automatic temp limit to prevent the purpose of electric hot-water bag superheated.When not having water or damaged bag in hot-water bottle, just occur Dry combustion method, once and the bag of dry combustion method phenomenon, then heating wire (or heat-generating pipe) support and electric hot-water bag occurs for heating wire (or heat-generating pipe) Body easily melts and burnt, so as to cause fire.Some present hot-water bottles are in order to prevent dry combustion method, with Thermal Cutoffs, Thermal Cutoffs is generally placed upon in product heating intracoelomic cavity and is connected with temperature controller, is directly filled with epoxy modeling fat.Due to temperature Spend and segmented state is between fuse and heating wire, in heating wire (or heat-generating pipe) dry combustion method during too high temperature, Temperature protection Silk differs and surely fuse and powered off in time to heating wire (or heat-generating pipe) in time, and Thermal Cutoffs does not play real anti-dry Effect.

Utility model content

The purpose of this utility model is that there is provided one kind for the defect that solves present in hot-water bottle anti-dry in the prior art The anti-naked light of hot-water bottle, anti-dry burning device.

To achieve these goals, the technical solution adopted in the utility model is：

A kind of anti-naked light of hot-water bottle, anti-dry burning device, including housing, are provided with heating wire, the outside of heating wire in housing Provided with heat-generating pipe, fixed temperature fuse on heat-generating pipe, Thermal Cutoffs is contacted and fitted with the surface of heat-generating pipe.

A kind of above-mentioned anti-naked light of hot-water bottle, anti-dry burning device, the housing include upper lid and lower cover, upper lid and lower cover it Between mutually fasten form cavity.

It is provided with and consolidating that the heating wire is connected in a kind of above-mentioned anti-naked light of hot-water bottle, anti-dry burning device, the cavity Reservation.

A kind of above-mentioned anti-naked light of hot-water bottle, anti-dry burning device, the heat-generating pipe is in the shape of a spiral.

The beneficial effects of the utility model are：Fixed temperature fuse on the heat-generating pipe of the device, Thermal Cutoffs and hair The surface of heat pipe is contacted and fitted, and when there is the situation of dry combustion method, temperature is passed to Thermal Cutoffs, temperature by heat-generating pipe in time The temperature that fuse is sensed can fuse at once in the upper limit more than Default Value, heat-generating pipe can power off in time stop into One step is heated, so as to effectively prevent that hot-water bottle from dry combustion method occur or even causing naked light, it is ensured that the service life and safety of hot-water bottle Coefficient.

Brief description of the drawings

Fig. 1 is schematic diagram of the present utility model.

Embodiment

As shown in figure 1, a kind of anti-naked light of hot-water bottle, anti-dry burning device, including housing 1, heating wire 2 is provided with housing 1, The outside of heating wire 2 be provided with heat-generating pipe 3, heat-generating pipe 3 in the shape of a spiral, fixed temperature fuse 7 on heat-generating pipe 3, Thermal Cutoffs 7 Contact and fit with the surface of heat-generating pipe 3.

Housing 1 includes upper lid 4 and lower cover 5, is mutually fastened between upper lid 4 and lower cover 5 and forms cavity, is provided with and electricity in cavity The fixed seat 6 that heated filament 2 is connected.

Fixed temperature fuse 7 on the heat-generating pipe 3 of the device, Thermal Cutoffs 7 is contacted and pasted with the surface of heat-generating pipe 3 Close, when there is the situation of dry combustion method, heat-generating pipe 3 passes to temperature Thermal Cutoffs 7 in time, what Thermal Cutoffs 7 was sensed Temperature can fuse at once in the upper limit more than Default Value, and heat-generating pipe 3 can power off stopping further heating in time, so that Effectively prevent that hot-water bottle from dry combustion method occur or even causing naked light, it is ensured that the service life and safety coefficient of hot-water bottle.

Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited in any way, For a person skilled in the art, the utility model can have various modifications and variations.It is all in spirit of the present utility model Within principle, any modifications, equivalent substitutions and improvements made etc. should be included within protection domain of the present utility model.
