When water is added, the motor works, water can be pumped from the water tank to the water outlet pipe through the water inlet pipe, enters the water inlet pipeline through the water outlet pipe, enters the water inlet channel through the water inlet pipeline, and enters the kettle body through the water inlet channel. In addition, when the water adding is stopped, the motor stops working, the residual water in the water inlet channel flows back into the water inlet pipeline and flows back to the water inlet pipe and the water tank through the water outlet pipe and the notch by the water inlet pipeline, no water is reserved in the water inlet channel and the water inlet pipeline, and the water inlet pipeline can prevent water drops in the water inlet pipeline from dripping or escaping when the kettle body is separated from the kettle seat. Moreover, when stopping adding water, by the evacuation in inhalant canal and inlet channel when water, can close the pipeline by the solenoid valve, even tea soup boils in cooking afterwards, the foam can cross the highest water level and get into inhalant canal, nevertheless because there is not the water, the foam can not mix into aquatic and get into the inlet channel with the help of water, therefore tea soup can not produce the pollution to water pump and water tank, can satisfy the requirement of boiling tea.

Preferably, in the above scheme, the kettle further comprises an upper coupler and a lower coupler, the upper coupler is arranged at the bottom of the kettle body, the lower coupler is arranged on the kettle seat, the water inlet channel is arranged at a central opening of the upper coupler, and the water inlet pipeline is arranged at a central corresponding opening of the lower coupler.

Thus, when the kettle body is placed on the kettle seat, the upper coupler and the lower coupler are coupled, the water inlet channel can be sleeved in the water inlet pipeline, and the water inlet channel is communicated with the water inlet pipeline.

Preferably, in the above scheme, the steam generator further comprises a steam collector and a spray cup. The steam collector can guide steam to enter the spraying cup, so that tea leaves in the spraying cup are sprayed by the steam, and the requirement of steaming the tea is met.

The electric heating teapot provided by the invention utilizes the gap in the water pump to gradually discharge residual water remained in the water inlet channel, the water inlet pipeline and the water outlet pipe during water adding to the water inlet pipe and the water tank, so that no water exists in the water inlet channel, the water inlet pipeline and the water outlet pipe, and the problem that water is easy to escape and affects a circuit when the pot body is separated from the pot seat can be fundamentally solved.

The utility model discloses an electric heating teapot, with the surplus water drainage of inhalant canal, inlet channel and outlet pipe to inlet tube and water tank, is automatic when the motor stop work and produces, need not need not the extra special operation of user, therefore, has convenient to use's characteristics.

This electric kettle only sets up the breach on the baffle in the water pump, then can carry out the residual water evacuation of inlet channel, inlet channel and outlet pipe when the motor stop work to, can prevent the effect that water carries out the conduction to tea soup, and the solenoid valve closes the pipeline and can block the possibility that the foam flowed into the water pump completely, solves water pump and water tank and probably receives the problem of tea soup pollution.

The electric heating teapot is very simple in structure, does not need to be provided with parts such as a return pipe, a return valve and the like in structure, is favorable for greatly reducing the production and manufacturing cost, is suitable for popularization and application, and can meet the requirements of people on steaming tea and realizing automatic water adding.
