Problems solved by technology

Since the charging interface is directly fixed in the first avoidance hole inside the housing, the charging interface is not fixed firmly, and it will slide to the inside of the housing when the force is applied, and when the charging interface slides to the inside of the housing, it is inconvenient to charge

Embodiment Construction

[0025] An electric warmer, comprising a housing, a circuit board fixed inside the housing, and a charging interface connected to the circuit board with wires, and a charging interface corresponding to the charging interface is arranged on the housing. Adapting to the first avoidance hole, the housing is provided with an interface limiting part matched with the charging interface, and the interface limiting part is located at the rear side of the first avoiding hole. In the present invention, since an interface limiting part matched with the charging interface is provided on the edge inside the housing, the charging interface will not move when the charging interface is fixed in the interface limiting part, and the charging interface is provided on the housing corresponding to the interface fixing part. The interface is compatible with the first avoidance hole, which is convenient for charging.

[0026] The present invention will be further described below in conjunction with t...

Abstract

An electric warmer comprises a shell body, a circuit board fixed inside the shell body and a recharging port that is connected to the circuit board through a wire. A first dodge hole matched with the recharging port is arranged on the shell body. A port stop part matched with the recharging port is arranged inside the shell body. The port stop part is arranged on a rear side of the first dodge hole. Because a port stop part matched with the recharging port is arranged on an edge of an inside of the shell body, the recharging port is fixed inside the port stop part and does not move. In addition, the first dodge hole matched with the recharging port is arranged on the shell body corresponding to the port stop part, facilitating recharging.

Description

technical field [0001] The invention relates to the field of hand warmers, and more specifically, to an electric warmer. Background technique [0002] With the improvement of people's living standards, electric heaters have become a must-have for families, not only for heating, but also for physical therapy or hot compresses. [0003] I have designed an electric heater, which includes a shell, an electric heater, a rechargeable battery fixed inside the shell to provide power for the electric heater, a switch for controlling the working state of the electric heater, a circuit board, and all The charging interface connected to the circuit board through wires and the heat conduction sheet arranged outside the housing, the housing is provided with a first avoidance hole adapted to the shape of the charging interface; the circuit board is provided with a control switch and The working indicator light, the electric heater and the circuit board are connected by wires, and the batt...
