Electric heating glass kettle

Abstract

Disclosed is an electric heated glass kettle, comprising a glass pot body, a handle arranged on the pot body and a bottom cover, wherein the bottom part of the pot body is provided with a heating plate, the heating plate comprises a main body, a heating body arranged on the main body and a silica gel ring, the bottom part of the pot body forms a neck, the silica gel ring and the main body are connected in a secure and sealed manner and enclose the neck, the neck is provided with a fastening ring, the bottom cover and the fastening ring are connected together, and the handle is directly or indirectly connected to the fastening ring. Compared with the prior art, the electric heated glass kettle provided in the present invention has the following advantages: in the present invention an embedded part of the fastening ring is secured and sealed with the main body of the heating plate as one piece, and then the neck of the pot body is enclosed by means of an elastic enclosing part of the silica gel ring, realising a flexible sealed connection between the heating plate and the pot body, thus ensuring a seal between the two, and also ensuring the structural integrity of the pot body with the handle and the bottom cover, while greatly reducing the techniques required for the pot body, improving assembly efficiency of the product.

Description

Technical field [0001] The invention relates to an electric heating glass kettle. Background technique [0002] Using glass as the kettle body has excellent performance and advantages, including the visibility of the heated liquid in the kettle body, and the excellent stability of the glass; [0003] At present, many patents for glass kettles have been published. In general, the first category is a technical solution for the entire glass kettle body, including adding an electric heating film or an electromagnetic conductive metal sheet at the bottom of the glass kettle body; the second category is only The glass pot body solution is used. At this time, an electric heater is needed 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 solution, this solution can have a large heating power and is suitable for rapid water boiling. In this way, the glass pot itself has no bottom, and at...

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.
