Abstract
The utility model relates to a device for heating water, in particular to an automatic power-off device for an electric water kettle. The automatic power-off device comprises a heating device arranged in the electric water kettle body, wherein, a spout of the electric water kettle body is hinged with a turning cover; the other side of the turning cover is connected with the electric water kettle body by a buckle. The automatic power-off device is characterized in that a switch device controlled by a wood plug is arranged in the turning cover; the switch device is connected in series with the power loop of the heating device. The automatic power-off device for an electric kettle can cut power supply when water is boiled. Moreover, once the power supply is cut off, the power supply can not be switched on again except artificial interference.
Description
Technical field
The utility model relates to a kind of device that adds hot water, is a kind of insulating pot auto-power-off device specifically.
Background technology
For using electricity wisely, avoid energy waste, existing insulating pot mostly is equipped with auto-power-off device, but these auto-power-off devices mostly are to judge whether outage by detected temperatures, promptly cut off the electricity supply by relay when temperature reaches certain value.There are two defectives in this auto-power-off device: 1, because the height above sea level difference, be different at the boiling point of different regions water, so just can cause the auto-power-off device that sets parameter in a certain area, it is malfunctioning to arrive another area; 2, after temperature reduced, relay can be connected power supply again, caused repeated priming, repeated heating.
Summary of the invention
The purpose of this utility model provides a kind of insulating pot auto-power-off device, and in a single day this device can be cut off the electricity supply in the water boiling, and cuts off the electricity supply, unless human intervention can not connected power supply once more.
For achieving the above object, this uses the following technical scheme of novel employing:
Insulating pot auto-power-off device described in the utility model comprises the heater that is installed in the kettle enclosure interior, the Hu Zuichu of kettle housing is hinged with and renovates, be connected by buckle between the opposite side of renovating and the kettle housing, it is characterized in that: in the installed inside of renovating the switching device that is controlled by stopper is arranged, this switching device is connected in the electric power loop of heater.
Described switching device comprises annular permanent-magnet body, the longitudinal axis, battery lead plate, and battery lead plate is provided with two electrodes that are concentric annular, is connected respectively in the electric power loop of heater; Battery lead plate and annular permanent-magnet body are fixedly mounted on the inboard of renovating abreast, and the longitudinal axis is inserted in the centre bore of annular permanent-magnet body and battery lead plate, is installed with the becket that permeability magnetic material is made on the longitudinal axis, and becket is between annular permanent-magnet body and battery lead plate.
After adopting technique scheme, in a single day insulating pot auto-power-off device of the present utility model can be cut off the electricity supply in the water boiling, and cuts off the electricity supply, unless human intervention can not connected power supply once more.
Description of drawings
Fig. 1 is the cutaway view of an embodiment of the present utility model;
Fig. 2 renovates inner structural representation.
The specific embodiment
As shown in Figure 1, insulating pot auto-power-off device described in the utility model comprises the heater 2 that is installed in kettle housing 1 inside, and the Hu Zuichu of kettle housing 1 is hinged with and renovates 3, renovates between 3 opposite side and the kettle housing 1 to be connected by buckle.In the installed inside of renovating 3 switching device is arranged, this switching device is connected in the electric power loop of heater 2.
As shown in Figure 2, described switching device comprises annular permanent-magnet body 5, the longitudinal axis 6, battery lead plate 7, and battery lead plate 7 is provided with two electrodes that are concentric annular, is connected respectively in the electric power loop of heater 2; Battery lead plate 7 and annular permanent-magnet body 5 are fixedly mounted on abreast renovates 3 inboard, the longitudinal axis 6 is inserted in the centre bore of annular permanent-magnet body 5 and battery lead plate 7, be installed with the becket 8 that permeability magnetic material is made on the longitudinal axis 6, becket 8 is between annular permanent-magnet body 5 and battery lead plate 7.The lower end of the longitudinal axis 6 be positioned at stopper 4 directly over, the upper end of the longitudinal axis 6 passes renovates 3, is arranged to the appearance of button.
When using, fill water in kettle housing 1, stopper 4 jam-packs at bottle mouth position, will be renovated 3 and covered and buckle well with buckle, this moment, the becket 8 on the longitudinal axis 6 contacted with battery lead plate 7 owing to the effect of gravity, and two electrodes are connected, and heater 2 gets electric work.When the water in the kettle housing 1 seethed with excitement, water vapour impacted stopper 4, and stopper 4 is with the longitudinal axis 6 jack-up, and becket 8 leaves battery lead plate 7, and power supply is cut off.Becket 8 is adsorbed by annular permanent-magnet body 5 after leaving battery lead plate 7 one segment distances, and it can not be fallen.When needs add hot water once more, need only the top that clicks the longitudinal axis 6 with hand, the absorption that makes becket 8 break away from annular permanent-magnet bodies 5 gets final product.
