Problems solved by technology

[0011] However, there are still some shortcomings in the above-mentioned further improvement scheme. Due to the limitation of devices and space height, etc., the volume change of the telescopic tube is limited, especially the problem that it takes a long time to restore its own length.
[0012] In addition, in the use of this type of electric kettle, when the water pump is working to add water to the kettle body, there is also the possibility that the user lifts or lifts the kettle body from the kettle seat. The pipe sprays around, which will cause a short circuit or electric shock hazard. In view of this possible situation, it must be resolved to eliminate this hidden danger

Abstract

The invention discloses a return valve, a water adding mechanism containing the return valve and an electric kettle containing the water adding mechanism; the return valve comprises a first valve bodyand a second valve body, the first valve body and the second valve body are respectively provided with a first port and a second port, and the two valve bodies are mutually sealed and a chamber is formed in the valve bodies. The return valve is characterized in that a compression spring, a piston component and a sealing component are arranged in the chamber, the sealing component is mounted on the piston component, the compression spring drives the sealing component to seal the first port through acting the piston component, and a water channel for enabling the piston component to be pushed to the second port is formed in the chamber. In this way, when the kettle body of the electric kettle is separated from a kettle seat, the return valve closes the first port, and meanwhile, the secondport is kept open, so that all or part of the residual liquid of a water inlet pipeline in the kettle seat flows to the interior of the return valve quickly. Another scheme is provided for eliminatingwater droplets that may drip or leak to a base or platform and preventing electric leakage from occurring.

Description

technical field [0001] The invention belongs to an electric kettle and its accessories, and relates to a valve suitable for water intake from the upper part of the kettle base through the bottom of the kettle body, more specifically, it is a valve that can allow the remaining water in the water inlet pipe of the kettle base when the kettle body is separated from the kettle base. The backflow valve for the backflow of water, the water adding mechanism containing the backflow valve and the electric kettle containing the water adding mechanism. Background technique [0002] At present, electric couplers have been widely used in electric kettles. It includes a lower coupler and an upper coupler. A plurality of ring-shaped metal electrodes are respectively arranged in the lower coupler and the upper coupler, and the upper coupler is inserted into the lower coupler. Electrical communication is achieved by contact of corresponding metal electrodes. The coupler can not only separat...
