Abstract

The invention provides a sealing structure of a window of an electric kettle, which comprises a kettle body provided with a window, the water window arranged on the window, and a pressure plate and a sealing ring arranged in the kettle body, wherein the water window is arranged inside or outside the kettle body and connected with the pressure plate; the sealing ring is compressively connected between the kettle body wall on the periphery of the window and the water window; the sealing ring, the water window and the pressure plate are orderly arranged in the kettle body; the pressure plate is annular, the bottom end of the pressure plate is fixedly connected or connected into a whole with the kettle body inner wall on the periphery of the window, and the top end of the pressure plate is provided with an in-flange which is compressively connected with the water window; and the sealing ring is compressed between the water window and the kettle body inner wall on the periphery of the window, the section of the sealing ring is square, and upper and lower sealing surfaces of the sealing ring are provided with two or more ribs. The water window is closely attached to the kettle body, and is sealed by the sealing ring between the kettle body and the water window; and the upper and lower sealing surfaces of the sealing ring are provided with the two ribs to increase line contact and improve sealing reliability. The sealing structure has the advantages of simple and reasonable structure, quick installation, firm connection, good sealing performance and suitability for mass production.

Description

technical field [0001] The invention relates to an electric kettle, in particular to a sealing structure for a water window of the electric kettle. Background technique [0002] The structural fixing methods of the existing stainless steel electric kettle water window mainly contain three kinds of welding, screwing and buckling. Among them, the welding method requires special machinery and equipment, which leads to an increase in cost. And the appearance is easy to scratch when welding. Although the fixing method of screwing does not require special machinery and equipment, it needs to screw many screws, which leads to low production efficiency and unattractive appearance. Chinese Patent No. ZL 03226225.6 discloses a window device for an electric kettle, including a kettle body and a water window. The kettle body has a window, and a sealing ring is arranged between the window and the water window. There are threads on the edge of the window and on the fixing frame. The w...
