Through setting up visor 4, debris such as outside dust, water can be prevented from getting into type-C interface 31, consequences such as bad contact or even electric energy meter fault damage appear in type-C interface 31.

Specifically, case 1 is provided with groove 12 recessed toward the inside of the watch, through-hole 11 is provided at the bottom of groove 12, and protective cover 4 is fitted in groove 12. By adopting the design, the outer surface of the protective cover 4 and the surface of the watch case 1 can be in smooth transition, and the influence on the appearance of the electric energy meter caused by steps can be avoided.

In this embodiment, one end of the groove 12 extends toward the outer side wall of the watch case 1 to form an opening 13 at a corresponding position on the outer side wall of the watch case 1, the protective cover 4 can be inserted into the groove 12 from the opening 13, the two side walls of the end of the groove 12 away from the opening 13 are provided with a limiting hole 14, the two sides of the protective cover 4 are provided with a rotating shaft 41 which can be inserted into the limiting hole 14 and rotate in the limiting hole 14, and the protective cover 4 can be opened by turning around the rotating shaft 41. In order to improve the protection performance of the protective cover 4, a receding groove 15 communicated with the limiting hole 14 is formed in one side, close to the opening 13, of the limiting hole 14, so that the protective cover 4 can move towards the opening 13 for a certain distance and then be turned over to be opened. By adopting the design, the end part of one end of the protective cover 4 far away from the opening 13 is tightly attached to the groove wall corresponding to the groove 12 when the protective cover 4 is in a covering state, so that the protective performance of the protective cover 4 can be improved, when the protective cover 4 needs to be opened, the protective cover 4 slides towards the opening 13 and then turns over to open the protective cover 4, if the abdicating groove 15 is not arranged, a wider distance needs to be reserved between one end of the protective cover 4 far away from the opening 13 and the groove wall of the corresponding groove 12, so that the protective performance can be reduced. In this embodiment, the connection position between the limiting hole 14 and the receding groove 15 is provided with a limiting protrusion 140 for preventing the protective cover 4 from slipping off from the limiting hole 14 when covering, and when covering the protective cover 4, the protective cover 4 is pushed towards the direction away from the opening 13, so that the rotating shaft 41 slides over the limiting protrusion 140.
