Description

Automatic flip kettle

Technical Field

The invention belongs to an electric heating device in the field of household appliances, relates to a heating kettle capable of automatically controlling a turnover cover by electricity, and particularly relates to an automatic turnover cover boiling kettle which is provided by improving a rotating mechanism of a kettle cover.

Background

In the prior art, the kettle is used for boiling water, a motor drives a kettle cover to rotate through a gear, the technology of automatically turning over the cover body is applied, the kettle cover can be automatically lifted upwards, an opening of a kettle body can be automatically closed, and the automatic water feeding in the whole process can be realized under the cooperation of a water outlet device under the control of a circuit.

At present, the kettle body and the kettle seat of most boiling kettles are independently separated, the current obtained by a circuit in the kettle body is provided by a power supply in the kettle seat through being matched with the kettle seat, and the kettle body is usually uncharged under the condition that the kettle body is separated from the kettle seat, so that the kettle cannot automatically lift the kettle cover under the condition that the boiling kettle is manually operated.

In addition, people often have the phenomenon that hands directly intervene in rotation due to habitual reasons, and manual operation causes the gear to rotate at a high speed due to large acting force, so that the gear is easily abraded and damaged, and the high-speed rotation causes a motor coil to generate strong instantaneous current, so that the possibility of burning out a motor and a circuit exists.

Furthermore, in the existing automatic lid-turning kettle structure, the lid is opened or closed, which means that the lid is lifted or closed and located at a certain position, so as to ensure the stability of the lid, for example, when closed, the lid is closed at the opening of the kettle body, so as to seal the opening of the kettle body, and there is no gap, and when opened, the lid is lifted, so as to be stable and not to reverse, in order to prevent the motor from continuing to rotate after the lid is opened or closed, which may cause the current increase and damage the motor and the circuit, the manufacturer usually needs to set a position switch and a detection circuit at the corresponding position of the two positions in design, so that the control circuit controls the motor to open and close according to the position signal provided by the detection circuit, which leads to the complication of the circuit and the increase of the manufacturing cost of the product.

Disclosure of Invention
