Vacuum cup with USB interface

Abstract

The invention provides a vacuum cup with a USB interface. The vacuum cup with the USB interface is characterized in that the cup body of the vacuum cup is provided with an inner layer, an outer layer formed by bending the cup opening of the inner layer, and an air layer formed by the inner layer and the outer layer in a spaced mode; the height, relative to the cup body, of the outer layer is larger than the height, relative to the cup body, of the inner layer; the cross section of the cup body is shaped like a Chinese character 'ao' without a bottom side; a separable electric heating device is arranged below the concave position of the inner layer and provided with the USB interface. According to the vacuum cup, due to the air layer of the cup body structure, heat of water can be isolated and prevented from being transmitted to the outer layer from the inner layer, the thermal insulation effect and the heat preservation effect are achieved, and the cup can be effectively prevented from scalding a hand; because the electric heating device is used for heating the inner layer of the cup body, the temperature of water is raised, and the functions of the cup are enriched; due to the USB interface, more convenience is provided for office workers.

Description

technical field [0001] The invention relates to daily necessities, in particular to a thermos cup with a USB interface. Background technique [0002] When using a cup to hold a liquid with a higher temperature in daily life, people often accidentally burn their hands. At present, using cups is generally made of pottery, plastics, glass, metal etc. In particular, materials with good heat transfer properties such as metal are selected, and the cup wall temperature is high, which is easy to burn hands and has poor heat preservation effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a thermos cup with a USB interface that prevents hot hands and has a heat preservation function. [0004] In order to solve the above technical problems, the present invention provides a thermos cup with a USB interface. The outer layer formed by bending, and the air layer formed by the separation between the inner layer and the o...
