Electric heating glass kettle

Abstract

Provided is an electric heating glass kettle. The electric heating glass kettle comprises a glass cup body, a handle and a bottom cover, wherein the handle and the bottom cover are arranged on the cup body. The bottom of the cup body is provided with a heating disc. The heating disc comprises a body, a heating element, and a silicon ring, wherein the heating element and the silicon ring are arranged on the body, a neck portion is formed at the bottom of the cup body, the silicon ring and the body are fixedly connected in a sealing mode and wrap the neck portion, the neck portion is provided with a fastening ring, the bottom cover is connected with the fastening ring, and the handle is directly or indirectly connected with the fastening ring. Compared with the prior art, the electric heating glass kettle has the advantages that an embedded portion of the silicon ring and the body of the heating disc are fixedly sealed into one, then an elastic wrapping portion of the silicon ring is used for wrapping the neck portion of the cup body, and therefore flexible sealing connection between the heating disc and the cup body is achieved. The sealing between the heating disc and the cup body is guaranteed, structural uniformity of the cup body, the handle and the bottom cover is guaranteed, meanwhile, technological requirements on the cup body are reduced greatly, and assembly efficiency of products is improved.

Description

technical field [0001] The invention relates to an electric heating glass kettle. Background technique [0002] Using glass as the body of the kettle has excellent performance and advantages, including the visibility of the heating liquid in the body and the excellent stability of the glass, etc.; [0003] At present, there are many kettle patents for glass kettle bodies that have been published. In general, the first category is the technical solution for the entire glass kettle body, including adding an electric heating film or a metal sheet for electromagnetic conduction at the bottom of the glass kettle body; The glass kettle body scheme is adopted. At this time, an electric heater is required at the bottom, which is generally an electric heating tube or a heating plate of an electric heating plate. Compared with the above electric heating film scheme, this scheme has a large heating power and is suitable for fast water boiling. In this way, the glass pot itself has no ...

AI Technical Summary

Problems solved by technology

[0008] The above technical solution has the following defects: 1. The connection between the opening of the main body and the heating element is a fastening connection. During processing, the heating element needs to be pressed against the main body to realize the connection between the two. The glass body may be damaged during the process; 2. Usually glassware is processed by blowing. This process determines that the opening shape of the glass body used to connect with the heating element will not be very accurate, including the connection The height, roundness, and diameter of the neck, and the neck is also prone to glass burrs or some small protrusions on individual points of the circle

[0010] When the heating plate and the glass pot body are tightly sealed and connected through the silicone ring, it is often difficult to ensure the cooperation of the handle / bottom cover and other structural parts when they are connected again, because the dimensional tolerance of the glass pot body is lower than the current technical means and price. It is uncontrollable. It often happens that the semi-finished product that is tested to be non-leakage after the heating plate is sealed with the body of the kettle enters the bottom cover / handle, thermostat, etc., and the water leakage occurs after the kettle is connected and installed, which makes the design of the production process difficult. , the assembly is not easy, the product quality cannot be guaranteed for a long time, and the requirements for the production process of the pot body are increased, which brings a series of problems such as an increase in cost.
