A kettle

Abstract

The present invention provides a kettle, especially an inlet valve structure for an electric tea kettle, wherein the inlet valve cover and the fixed valve body are sealed by a large O-ring. When the valve core (central tube) is pressed down, the water in the valve cover can enter the central tube. When the central tube is lifted up by a spring, the water in the valve cover is sealed and the water will not flow out of the central tube. When the middle O-ring is opened, the water enters the central tube. Since there are double layers of small O-rings sealed on the outside of the central tube, the water between the fixed valve body and the central tube is sealed in the fixed valve body. When the central tube is lifted up by a spring, the middle O-ring on the outside of the central tube is sealed with the fixed valve body to prevent water from entering the central tube, prevent water from overflowing, and solve the potential safety hazard. The valve structure of the present invention is applied to the electric tea kettle, which can realize the internal sealing of the pumping system, prevent water from overflowing, and prevent water from splashing onto the power carrier when the pump is pumping water, solve the potential safety hazard of the electrical system, optimize product performance, and improve user experience.

Description

Technical Field

[0001] The present invention relates to a kettle, and in particular to a water inlet valve structure of a kettle. Background Art

[0002] The existing kettles on the market, such as electric kettles, usually have the water boiling part and the water pumping part separated. In the process of heating the water to pouring or using the boiled water, it is inevitable that the kettle body and the water pumping base are separated, and the kettle body is put back on the water pumping base to continue pumping water. In this process, it is inevitable that the flowing water will be spilled outside the container body and on the appliance table. The outflow and splashing of water not only affects the user experience, but also poses a great possibility of electrical safety hazards, such as leakage and even injury. In home and public use environments, it seriously affects the user experience and reduces the comfort of product use.
