Electric heating cup

Abstract

The invention relates to an electric heating cup. The electric heating cup comprises a cup body, a water boiling cavity, a heating plate and an electric control device are arranged on the cup body, the heating plate comprises a heating surface and an installing bottom surface, an installing hole is formed in the water boiling cavity, the heating plate is arranged inside the installing hole, the heating surface of the heating plate is located inside the water boiling cavity, and the installing bottom surface of the heating plate is located outside the water boiling cavity. The installing bottom surface of the heating plate is connected with an installing base, a temperature sensing element installing groove is formed in the surface, close to or making contact with the heating plate, of the installing base, a temperature sensing element and an elastic body are arranged inside the temperature sensing element installing groove and are arranged on the upper portion and the lower portion respectively, and the temperature sensing element elastically makes contact with the installing bottom surface of the heating plate. Through arranging the installing base on the installing bottom surface of the heating plate, the installing base serves as an installing carrier of the temperature sensing element and the elastic body and enables the temperature sensing element to elastically make contact with the installing bottom surface of the heating plate all the time, in this way, the heating temperature of the heating plate is monitored, and dry boiling is prevented.

Description

technical field [0001] The invention relates to an electric heating cup, which is especially suitable for boiling water and coffee; it can be used in homes, vehicles or other places with electricity. Background technique [0002] Existing electric heating cups, such as: vehicle-mounted electric heating coffee cups, most of which are Chinese invention patent number: 201320775935.8, named "vehicle electric heating coffee cups", and its authorization announcement date: August 27, 2014, including the cup body and the lower end of the cup body A heating device is provided. The heating device is composed of an electric heating element and a temperature adjustment device. The electric heating element is located on the bottom surface of the cup body. A temperature sensing head is installed in the heating device. One end of the temperature sensing head is placed in the cup body, and the other end is connected to the temperature adjustment device The device is connected, the lower end...

AI Technical Summary

Problems solved by technology

[0006] The electric heating cup includes a cup body, the cup body is provided with a water boiling cavity, a heating plate and an electric control device, the heating plate includes a heating surface and an installation bottom surface, the boiling water cavity is provided with an installation hole, and the heating plate is arranged on the installation hole , and the heating surface is located in the water boiling chamber, and its installation bottom surface is located outside the water boiling chamber. It is characterized in that the installation bottom surface of the heating plate is connected with a mounting seat, and the surface of the mounting seat close to or in contact with the heating plate is provided with a temperature sensor Component installation groove, temperature sensing element and elastic body are arranged in the temperature sensing element installation groove, and the temperature sensing element is arranged on the top and the elastic body is on the bottom. The electric control device is electrically connected; this type of electric cup is provided with a mounting seat on the bottom surface of the heating plate, and the mounting seat is used as the mounting carrier of the temperature sensing element and the elastic body, so that the temperature sensing element is always in elastic contact with the bottom surface of the heating plate. In order to ensure the monitoring of the heating temperature of the heating plate and achieve the purpose of preventing dry burning, and this temperature sensing element is arranged outside the boiling water chamber without using a sealing ring, which overcomes the poor sealing performance and inconvenient use of the sealing ring in the prior art. Hygienic defects; moreover, the whole structure is simple and reasonable, not only suitable for AC (such as: home, office) use, but also suitable for use on vehicle direct current with large vibration
