Intelligent electric hot water bag hand-warming device

Abstract

The invention discloses an intelligent electric hot water bag hand-warming device which comprises a body. A vacuum layer is wrapped in the body, and a control box, a display screen, a power interface, a temperature sensor and a resistance strain type pressure sensor are arranged on the surface of the body. A control circuit board, a miniature vacuum machine and a battery box are arranged in the control box. The intelligent electric hot water bag hand-warming device can conduct intelligent heat preservation and heat dissipation control on an electric hot water bag, and electric energy loss brought by charging time prolonging due to the heat dissipation problem in the charging process of the electric hot water bag is avoided. In addition, it is also guaranteed that automatic heat dissipation does not occur as time goes on when the device is not used after the electric hot water bag is full of electricity, and a heat preservation effect is played, so that the user can use the device under any condition. In addition, by arranging the display screen, the user can monitor the temperature in the electric hot water bag ay any time and accordingly select the temperature suitable for the user.

Description

technical field [0001] The invention relates to the technical field of heating auxiliary equipment, in particular to an electric hot water bag intelligent hand warmer. Background technique [0002] Electric hot water bag is one of necessary supplies for people to warm their hands and feet in winter. Although there are many kinds of electric hot water bags at present, there is a common problem, that is, the electric hot water bag itself is always in a state of heat dissipation no matter during the charging process or after the charging is completed; In the winter environment, it will be cold for a while, and it has to be recharged when it needs to be used, which has brought some troubles to people; in addition, the electric hot water bag cannot keep warm during the charging process, and there is heat loss, which also increases the loss of electric energy. , can not meet the requirements of environmental protection. Contents of the invention [0003] The purpose of the pre...
