Abstract
The utility model discloses a pressure type electric hot-water bag which comprises a hot-water bag body and further comprises a constant-temperature heating control circuit arranged in and electrically connected with the hot-water bag body. The constant-temperature heating control circuit is connected to an external power supply through an electric plug. The constant-temperature heating control circuit comprises a manual switch, a pressure relay and a constant-temperature controller, wherein the manual switch, the pressure relay and the constant-temperature controller are sequentially connected in series. When the hot-water bag body is pressed, a pressure relay contact is automatically disconnected, and a circuit in the hot-water bag body is automatically disconnected. When the hot-water bag body is not pressed, the pressure relay contact automatically closes, and the circuit in the hot-water bag body is automatically connected. The pressure type electric hot-water bag is simple in structure and convenient to use, when the hot-water bag is electrically heated, the hot-water bag can be directly used for warming the hands without turning off a switch or pulling off a plug, when the hot-water bag is pressed by the pressure on the hands, the circuit of the pressure relay is automatically disconnected, use safety is better, potential safety hazards are reduced, and popularization and use are facilitated.
Description
Technical field
This utility model relates to a kind of pressure-type electric hot water bag.
Background technology
Now people generally can use electric hot-water bag winter, and the sort of electric hot-water bag temperature arrives after certain value will automatic shutoff circuit, and then people just can pull up plug and use hot water bag.When there is no temperature in hot water bag, heating again need to plug in.So circulation bothers very much.Easily cause electrical equipment to damage, increase potential safety hazard.
The utility model content
This utility model purpose is to provide a kind of pressure-type electric hot water bag for the defective that prior art exists.
This utility model for achieving the above object, adopt following technical scheme: a kind of pressure-type electric hot water bag, comprise the hot water bag body, also comprise being arranged in described hot water bag body and the heated at constant temperature control circuit that is electrically connected to it, described heated at constant temperature control circuit is connected on external power source by plug; Wherein, described heated at constant temperature control circuit comprises switch, pressure switch and the radiator valve of serial connection successively; When described hot water bag body pressurized, the contact automatic disconnection of described pressure switch, the circuit in the hot water bag body is cut off automatically; When described hot water bag body not during pressurized, described pressure switch contact auto-closing, the circuit in the hot water bag body is connected automatically.
The beneficial effects of the utility model: this apparatus structure is simple, easy to use, do not need closing switch or pull up plug directly to be used for warm hand after the hot water bag electrical heating yet, pressure switch automatic shutoff circuit when pressure is pressed onto hot water bag on hand, safety in utilization is better, reduce potential safety hazard, be convenient to universal the use.
Description of drawings
Fig. 1 is that system of the present utility model forms schematic diagram.
The specific embodiment
In Fig. 1, for a kind of pressure-type electric hot water bag, comprise hot water bag body 1, also comprise being arranged in described hot water bag body 1 and the heated at constant temperature control circuit that is electrically connected to it, described heated at constant temperature control circuit is connected on external power source by plug 5; Wherein, described heated at constant temperature control circuit comprises hand switch 2, pressure switch 3 and the radiator valve 4 of serial connection successively; When described hot water bag body 1 pressurized, described pressure switch 3 contact automatic disconnections, the circuit in hot water bag body 1 is cut off automatically; When described hot water bag body 1 not during pressurized, described pressure switch 3 contact auto-closings, the circuit in the hot water bag body is connected automatically.
During use, plug 5 is received on external power source, closed hand switch 2, circuit is in running order, and after heating a period of time, user is placed on hands on hot water bag when hot water bag, after hot water bag is under pressure, and the circuit automatic disconnection.After hands was taken away from hot water bag, circuit auto-closing, hot water bag began to continue heating.Wherein, radiator valve 4 has secondary protection function.After the water temperature in hot water bag reached predetermined value, radiator valve 4 also can automatic disconnection or closed circuit, and just carry out second protection to circuit this moment.
The above is only preferred embodiment of the present utility model, and is in order to limit this utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
