Abstract
A sealing structure for a heating component comprises the heating component arranged in a kettle body. The kettle body and the heating component form a heating cavity capable of storing liquid. The sealing structure is characterized in that the heating component is assembled by a heating coil and/or heating tube, a stressed turning portion with a small opening and a large inner cavity is arranged on the periphery of the heating component, the inner cavity of the stressed turning portion extrudes a stressed portion on a silica gel sealing ring to form an opening heating component, and a heating component inner wall is formed on the inner side of the silica gel sealing ring and the upper portion of the heating component. By extruding the silica gel sealing ring by the inner cavity of the stressed turning portion, the inner wall of the heating component is hermetically connected with the kettle body by pressing, sealing performance of an electric heating kettle is improved, and the problems of poor sealing, dislocation, water leakage and seepage and the like can be effectively prevented. A silica gel sealing ring is arranged on the heating component so as to make positioning surfaces of the silica gel sealing ring and the heating component cylindrical to guarantee the centers of two parts on the same central line, eccentricity during assembling is effectively overcome, tightness in connection of the heating component and the silica gel sealing ring is guaranteed by the stressed turning portion, and sealing performance of the heating component is improved. The sealing structure has the advantages of simple and reasonable structure, quickness in assembling, reliability in performance and long service life, and rejection rate can be decreased effectively.
