The heating device is characterized in that a temperature controller is connected with the heating tube, a joint of the heating tube is firstly sealed by hard materials in an insulating manner, then the joint of the heating tube and the power cords of the heating tube are wrapped by a PVC (polyvinyl chloride) material by means of injection molding again, a metal shell fixedly wraps the heating tube and the temperature controller integrally, an insulating channel with an end surface extends on the insulating casing, the power cords are placed in the insulating channel, and the end surface of the insulating channel and an end surface of the PVC material at the joint of the heating tube are formed by means of high-frequency heat sealing. Accordingly, the hot water bottle can be protected against being burned even under a condition without water or a condition of dry burning, and the heating device has the advantages of safety, practicality, compact structure and reasonable arrangement.
Description
Technical field
The utility model relates to the heater that a kind of explosion-proof electric hot-water bag is used.
Background technology
Electric hot-water bag generally includes the outer bag of a sealing, bag inside has heat-storage medium and heater, the insulation crust that heater has and the sealing of outer bag is provided with, power pin and indicator light all are arranged on the insulation crust, the heating resistor that insulation crust inner chamber lower end is equipped with the double temperature control device and is connected with thermostat, thermostat and heating resistor are not an integral body, and both connect by lead, and the relative insulation crust of heating resistor can rive off.Heating resistor heats heat-storage medium behind the hot-water bottle power connection, and thermostat is measured temperature from heat-storage medium, after heat-storage medium reaches design temperature, and thermostat work deenergization, heating is finished.But, when hot-water bottle is in tilted-putted the time, perhaps the hot-water bottle heat-storage medium leaks outside, and at this moment, thermostat can't touch heat-storage medium, no matter how high heat-storage medium and heating resistor temperature have, thermostat can't measure the temperature of heat-storage medium and heating resistor, and under the situation that does not have water or dry combustion method, heating resistor is worked always and can be burnt out whole hot-water bottle, and may cause hot-water bottle expansion blast, exist potential safety hazard.
The utility model content
At the defective that exists in the prior art; the purpose of this utility model is to provide a kind of heater of explosion-proof electric hot-water bag, even can protect hot-water bottle not burnt out under the situation that does not have water or dry combustion method, and has safe and practical; compact conformation is provided with rational characteristics.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of heater of explosion-proof electric hot-water bag, include the insulation shell that outer bag sealing is provided with hot-water bottle, power pin and indicator light are arranged in the insulation shell, heating tube links to each other with power pin by power line, it is characterized in that: described heating tube is connected with thermostat, heating tube joint and power line injection moulding for the first time hard plastic insulated enclosure, heating tube joint after sealed and power line thereof are injection molding for the second time with PVC material parcel, metal shell is with heating tube, the fixing parcel of thermostat is in aggregates, insulation shell extends the insulated channel of the placement power line of a band edge face, and the PVC material end face of this insulated channel end face and heating tube joint is by the high frequency heat seal moulding.
Described thermostat is made up of common thermostat and irrecoverable thermostat.
Described common thermostat and irrecoverable thermostat are built in the middle part that heating tube forms, has filler on the metal shell, fluid sealant is infused in the metal shell by filler, and common thermostat and irrecoverable thermostat and the whole sealing and fixing of power line are in metal shell.
Also be extended with plug before the PVC material end face that wraps up on the described heating tube, plug inserts in the insulated channel, makes convenient applying of two end faces be convenient to carry out the high frequency heat seal operation.
Described metal shell for up and down two be formed by connecting, following metal shell sheet is provided with the fluid sealant filler.
Described metal shell is that aluminium or copper become.
Described metal shell periphery is with dismountable high temperature resistant silicon gum cover outward.
Described thermostat and metal shell fit tightly.
Described heating tube is bent to form circle or ellipse.
Adopt the electric hot-water bag heater of said structure, thermostat is built in the middle part that heating tube forms, and formed an integral body by metal shell, fluid sealant and heating tube, heating tube, thermostat and metal shell fit tightly, when heating tube heats, the metal shell that outer wrapping is given thermostat with temperature transfer, and what thermostat measured is the temperature of heating tube.So, no matter hot-water bottle be how tilt to place or the hot-water bottle bag in water leak outside or do not have can be when arriving uniform temperature under the situation of water, the thermostat effect, deenergization can play a protective role.And heating tube also is connected with an irrecoverable thermostat, and when common thermostat was malfunctioning, irrecoverable thermostat can deenergization, plays duplicate protection, safety very.In addition: the insulated channel end face that heating tube joint and power line form PVC material end face and insulation shell by insulating material sealing and secondary carries out high frequency heat seal and is connected to form firm heater, can prevent that heating tube from touching outer bag, use safelyr, compact conformation is provided with rationally.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2, shown in Figure 3, a kind of heater of explosion-proof electric hot-water bag, include the insulation shell 1 that outer bag sealing is provided with hot-water bottle, power pin 2 and indicator light 3 are arranged in the insulation shell 1, heating tube 4 links to each other with power pin 2 by power line 5, heating tube 4 is connected with common thermostat 6 and irrecoverable thermostat 7, common thermostat 6 and irrecoverable thermostat 7 are built in the middle part that heating tube 4 is bent to form, heating tube 4 joints and power line injection moulding for the first time hard plastic material 41 insulated enclosures, heating tube 4 joints after the sealing and power line 5 thereof are injection molding once more with PVC material 42 parcels, and metal shell 8 is with heating tube 4, common thermostat 6, irrecoverable thermostat 7 fixing parcels are in aggregates.Wherein, metal shell 8 for up and down two be formed by connecting, following metal shell sheet is provided with fluid sealant filler 81, and fluid sealant is infused in the metal shell 8 by filler 81, common thermostat 6 and irrecoverable thermostat 7 and power line 5 sealed being fixed in the metal shell 8.
