Abstract
The utility model discloses a heating device of an electric hot water bag, which comprises an insulating casing sealed to an outer bag, a socket arranged at the top of the insulating casing, a temperature controller arranged at the lower end of the insulating casing and a heating resistor connected to the temperature controller. The heating resistor is built inside a fixing block which is injection molded with a PVC (polyvinyl chloride) material and insulating sealed through a connector, an insulating end surface is formed on the top of the fixing block, an insulating channel extends out the insulating casing to be connected integrally with the insulating end surface of the fixing block through high frequency thermal bonding, and power lines are built inside the insulating channel and connected with the heating resistor and the temperature controller. A protective frame is arranged outside the heating resistor so as to improve safety, and the insulating casing and the heating resistor are connected into one stable piece, thereby being safe in usage, compact in structure and reasonable in arrangement.
Description
Technical field
The utility model relates to the heater of electric hot-water bag, is specially the heater that a kind of electricity separation electric hot-water bag is used.
Background technology
The heater of electric hot-water bag employing at present, generally by housing, thermostat and heating resistor are formed, its middle shell includes shell body and inner housing, shell body is provided with on the electric hot-water bag bag, power pin and indicator light all are arranged on the shell body, inner housing is arranged in the bag, in the inner chamber of inner housing upper end thermostat is installed, the inner housing lower end is provided with heating resistor, thermostat all is to link to each other by power line with socket on heating resistor and the shell body, some also is exposed at the outside present power line, although power line is enclosed with insulation crust, is immersed in the liquid unsatisfactory for a long time.In addition, the locality between heating resistor and the shell body can not be fixed, and heating resistor opposite shell cognition rives off, and breaks the shell body of electric hot-water bag easily, need do further to adjust to the structure of heater.
The utility model content
At the defective that exists in the above-mentioned prior art, the purpose of this utility model is to provide the heater of electric hot-water bag, has compact conformation, is provided with rationally, and the hot-water bottle touch feeling is good, the characteristics of safe ready.
Above-mentioned purpose is achieved through the following technical solutions:
The heater of electric hot-water bag, include an insulation crust that sealing is provided with outer bag, the socket that is arranged on the insulation crust upper end, the heating resistor that the insulation crust lower end is provided with thermostat and is connected with thermostat, wherein have power pin and power supply indicator on the socket, it is characterized in that: described heating resistor is built in the fixed block by PVC material injection mo(u)lding insulated enclosure by its joint, and the fixed block upper end forms an insulation end face; Described insulation crust extends the insulated channel of a band edge face, and insulated channel and fixed block insulation end face link into an integrated entity by the high frequency heat seal mode, and power line is built in insulated channel and links to each other with thermostat, and heating resistor is outside equipped with a protective frame.
Described thermostat is made up of two thermostats, and the 1st thermostat is arranged on the insulation crust lower end, and the 2nd thermostat is provided with in the fixed block inner chamber, plays double protection.
Described protective frame is made up of two protective frame, is provided with fixing hole above the protective frame, and two protective frame merge outer heating resistor and the fixed block of covering in fixing back.
Described protective frame is that hard plastic material or silica gel material are made.
Described heating resistor is two METAL HEATING PROCESS resistance.
Adopt the electric hot-water bag heater of said structure, heating resistor is built in the fixed block that is formed by the sealing of PVC insulated with material by its joint, the insulation end face that the fixed block upper end forms and the insulated channel end face high frequency heat seal of insulation crust form one, the outer power line of insulation end face is built in and interior the connection with thermostat of insulated channel can improves fail safe, insulation crust and heating resistor connect into a firm integral body, use safer, compact conformation, be provided with rationally, can prevent that heating resistor from touching outer bag, the user only can touch outer bag, has increased feel.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As Fig. 1, Fig. 2, shown in Figure 3, the heater of electric hot-water bag, include one and insulation crust 1, the socket 2 that is arranged on insulation crust 1 upper end, insulation crust 1 lower end of outer bag sealing setting be provided with the 1st thermostat 31, wherein have power pin 21 and power supply indicator 22 on the socket 2, insulation crust 1 upper end face has the outer rim 12 with outer bag sealing.Insulation crust 1 extends the insulated channel 11 of a band edge face.Heating resistor 4 is built in by its joint 41 in the fixed block 5 that is formed by PVC material injection mo(u)lding insulated enclosure, and fixed block 5 upper ends form an insulation end face 51; The 2nd thermostat 32 is arranged in the inner chamber of fixed block 5, fixed block insulation end face 51 and insulated channel 11 link into an integrated entity by the high frequency heat seal mode, two protective frame 6 merging cover fixed block 5 and heating resistor 4, play protective action, power line is built in insulated channel 11 inner gang sockets 2, thermostat 31,32 and heating resistor 4, this moment heating resistor 4 and insulation crust 1 both form an integral body, the no longer relative insulation crust 1 of heating resistor 4 has and swings, structure is firm, uses fool proof.
The protective frame 6 that is provided with outside fixed block 5 and heating resistor 4 is made for hard plastic material or silica gel material, merges by hold-doun nut to form.
The above, it only is better embodiment of the present utility model, be not that utility model is done any pro forma restriction, every foundation know-why of the present utility model still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations or modification that above embodiment did.
