Abstract
Disclosed is an electric water-heating bag with double temperature control, comprising a bag body and a heating device which consists of a casing, two thermostats and a heating resistor. The casing is divided into an inner casing and an outer casing, wherein, the outer casing acts as an outer power connection and the inner casing is arranged in the cavity of the bag body. The two thermostats are disposed on the inside of the inner casing that is filled with insulating resin to insulate and fix to the thermostats. The heating resistor is arranged in the cavity of the bag body. The electric water-heating bag with double temperature control has the advantages of simple inner structure, safe and reliable automatic temperature control and long service life.
Description
Technical field
The utility model relates to a kind of warming appliance of family expenses, specifically is a kind of electric hot-water bag that has double temperature control.
Background technology
The hot-water bottle that uses mainly contains electric hot-water bag and artificial changing water formula hot-water bottle at present, and artificial changing water formula hot-water bottle is safe in utilization, and effect is also good, seems cumbersome but change the water process; And electric hot-water bag just in time can overcome the deficiency of artificial changing water formula hot-water bottle, as long as power supply is arranged just can heat to the water in the bag, but general electric hot-water bag exists certain potential safety hazard in the process of heating, at first heating is to adopt the ionization heating, at this moment the water in the water bag is charged, the accident of electric shock takes place easily, heating-up temperature need manually be gone perception in addition, make the interior water vapor of bag as long meeting heating time, thereby a bag internal pressure is increased greatly, the overinflation of bag has influence on the useful life of hot-water bottle, and is serious even hot-water bottle is broken.
The utility model content
At above technical deficiency, the purpose of this utility model is to provide a kind of electric hot-water bag of double temperature control, and it is simple to have internal structure, and is automatic temperature-controlled safe and reliable, the characteristics of long service life.
For achieving the above object by the following technical solutions:
A kind of electric hot-water bag comprises bag and heater, described heater is by housing, thermostat, heating resistor is formed, housing is divided into inner housing and shell body, wherein shell body is as the power supply coupling, and be provided with indicator light, inner housing is arranged in the inner chamber of bag, two thermostats are arranged on the inside of inner housing, heating resistor is installed in the inner housing lower end and is connected with thermostat, the inner resin with insulation of inner housing is filled, thereby thermostat and heating resistor are insulated and fix, shell body and water filling port are installed on the bag, the combination of both and bag is heated by high frequency and is bonded, and the thermostat on the inner housing connects into a circuit that communicates with heating resistor and external power joint with high temperature electric wire.
The utility model has been settled a heating resistor in the bag of hot-water bottle, feasible heating to cold water does not need to use the ionization heating, in heating process, just heat and seem safe than ionization mode, the utility model is provided with two thermostats on the inner housing of heater in addition, as long as two temperature controls are not simultaneously broken down, too high and damage the danger of hot-water bottle with regard to not making water temperature in the hot-water bottle, can prolong the useful life of hot-water bottle; Insulation of the present utility model adopts the resin of insulation to make insulating properties better, with the shell of heater bag is sealed, and makes the structure of hot-water bottle more become simple.To have internal structure simple, automatic temperature-controlled safe and reliable for the electric hot-water bag that provides of the utility model thus, the characteristics of long service life.
Description of drawings
Fig. 1 is an internal structure schematic diagram of the present utility model;
Fig. 2 is the circuit diagram of heater of the present utility model.
Embodiment
As shown in Figure 1, a kind of electric hot-water bag comprises bag 1 and heater, described heater is by housing 21, thermostat 22, heating resistor 23 is formed, housing 21 is divided into shell body 211 and inner housing 212, wherein shell body 211 is as the power supply coupling, and be provided with indicator light 213, inner housing 212 is arranged in the inner chamber of bag 1, two thermostats 22 are arranged on the inside of inner housing 212, heating resistor 23 is installed in inner housing 212 lower ends and is connected with thermostat 22, inner housing 212 inner resins 4 with insulation are filled, thereby thermostat 22 and heating resistor 23 are insulated and fix, shell body 211 and water filling port 3 are installed on the bag 1, the combination of both and bag 1 is heated by high frequency and is bonded, and the thermostat 22 on the inner housing 212 connects into a circuit that communicates with heating resistor 23 and external power joint with high temperature electric wire.
The circuit of heater as shown in Figure 2.During use, external power is connected in the power supply coupling on the shell body 211, and thermostat 22 is a normally closed switch, circuit communication, indicator light 213 is bright, and heating resistor 23 is heated, water heat absorption in the hot-water bottle, water temperature is elevated to the assigned temperature of thermostat 22 certainly, and thermostat 22 disconnects, thereby circuit disconnects, indicator light 213 goes out, and no longer to heating resistor 23 heating, temperature is certain, pull out external power supply, just can use hot-water bottle safely.
Claims (2)
