CN2358784Y - Electric teapot avoiding heating without water - Google Patents

Abstract

The utility model relates to an electric teapot which avoids from heating without water. A heater is fixedly arranged in a teapot body, and the extending section of the tail end of the heater extends out of the teapot body. The outer side of the teapot body is fixedly provided with a shell seat, the shell seat is fixedly provided with two connector pins, the outer ends of the two connector pins can be used for inserting a socket of a power-supply wire, and the inner end of one of the connector pins is connected with the extending section of the heater through a conducting wire. The teapot body is fixedly provided with a heat conduction seat, the inner end of the heat conduction seat is buckled with the heater, the outer end of the heat conduction seat is assembled with a temperature controller, and the temperature controller is connected in series to the middle position of the heater and a circuit of the other connector pin. The inner end of the heat conduction seat forms an inserted opening, and the heater is bent into a supporting section which is buckled with the inserted opening. The utility model can prevent from heating without water by that the electric teapot heats continuously, and therefore, the fire can prevent from being generated through the timely power cut.

Description

The electric teapot of preventing dry combustion

The utility model relates to a kind of electric teapot of preventing dry combustion, refers to especially a kind ofly can the liquid in kettle body heating is reduced to one a small amount of and when improving temperature, cut off the electricity supply immediately to prevent the preventing dry combustion structure of its empty electric teapot that burns in its heater.

See also shown in Figure 5ly, general electric teapot sets firmly heater 20 in kettle body 10, and 20 liang of tip end projects of heater go out the kettle body 10 outer latches 201 that form, and pegs graft and conductive heater for the socket of power line, then can be to the liquid warming in the kettle body 10.Yet because general electric teapot edge does not have the preventing dry combustion structure, regular meeting allows heater 20 continue heating because of forgetting, kettle body 10 interior liquid is dryouied, and cause empty the burning, even can cause fire.

The purpose of this utility model is to provide a kind of electric teapot of preventing dry combustion, when heater with the kettle body in liquid heating be reduced to one default a small amount of and when being promoted to a preset temperature, temperature controller can cooperate the heat-conducting seat perception and be and open circuit, the heating so that heater is no longer switched on can prevent the empty burning of electric teapot by this.

The purpose of this utility model is achieved in that a kind of electric teapot of preventing dry combustion, in the kettle body, set firmly heater, and it is external that the extension of heater end stretches out kettle, the external shell block that sets firmly of this kettle, set firmly two latches on the shell block, but the socket of two latch outer end power supply source lines is pegged graft, and one latch the inner connects the extension of heater by lead; This kettle body sets firmly a heat-conducting seat, the inner buckle heater of heat-conducting seat, and heat-conducting seat outer end winding one temperature controller, and temperature controller is serially connected with in the middle of the circuit of heater and another latch.

The inner embedding mouth that forms of this heat-conducting seat, heater curves the section of accepting with embedding mouth buckle.

By said structure, the utility model can prevent that electric teapot from continuing heating and empty the burning as can be known, even by the ground outage, by this to prevent the generation of fire.

Below in conjunction with accompanying drawing and specific embodiments, the utility model is described further.

Fig. 1 is a side sectional view of the present utility model;

Fig. 2 is a side sectional view of the present utility model;

Fig. 3 is an overlooking surface cutaway view of the present utility model;

Fig. 4 is a circuit block diagram of the present utility model;

Fig. 5 is a structural representation of the present utility model.

At first referring to shown in Fig. 1-4, the utility model sets firmly heater 2 in kettle body 1, and it is external that the extension 21 of 2 liang of ends of heater stretches out kettle, this kettle body 1 outer appropriate location sets firmly shell block 3, set firmly two pins 4 on the shell block 3, but the socket 51 of two latches, 4 outer end power lines 5 is pegged graft, and one latch 4 the inners connect the extension 21 of heater 2 by lead 41; Moreover kettle body 1 sets firmly a heat-conducting seat 6, heat-conducting seat 6 is inner form embedding mouths 61 for the section of accepting 22 buckles of heater 2 curved arcs, and heat-conducting seat 6 outer ends can ccontaining winding one temperature controller 7 (can be general thermistor switch); Temperature controller 7 is serially connected with 4 of heater 2 and another latches in circuit, can be when each preset temperature of temperature controller 7 perception and open circuit.

During use, the socket that power line is inserted in wall to be obtaining power supply, and via the grafting of socket 51 and latch 4, power supply offered temperature controller 7 and heater 2, and then heater 2 just can be to the heating of the liquid in the kettle body 1.When heater 2 is reduced to one when default a small amount of with the liquid in the kettle body 1 heating, when the temperature of heater 2 can improve, then temperature controller 7 is understood by the heat conduction of heat-conducting seat 6 this temperature of perception, and when reaching to a preset temperature, temperature controller 7 can be and open circuit, the heating so that heater 2 is no longer switched on continues heating and empty the burning to prevent it.

Claims (2)

1, a kind of electric teapot of preventing dry combustion, in the kettle body, set firmly heater, and it is external that the extension of heater end stretches out kettle, it is characterized in that: the external shell block that sets firmly of this kettle, set firmly two latches on the shell block, but the socket of two latch outer end power supply source lines is pegged graft, and one latch the inner connects the extension of heater by lead; This kettle body sets firmly a heat-conducting seat, the inner buckle heater of heat-conducting seat, and heat-conducting seat outer end winding one temperature controller, and temperature controller is serially connected with in the middle of the circuit of heater and another latch.

2, the electric teapot of preventing dry combustion as claimed in claim 1 is characterized in that: the inner embedding mouth that forms of this heat-conducting seat, heater curves the section of accepting with embedding mouth buckle.
