[0012] 2. In the utility model, many mosquitoes and insects will gather in the area where the electric energy meter is located under the attraction of bright light and warm environment. The large-scale entry of insects will bring more impurities, thereby reducing the air intake efficiency of the dust filter plate, and the insects may even cause a short circuit inside the electric energy meter. By arranging slots, medicine boxes, positioning plates A, positioning plates B, and latches, not only can the work of placing medicine and repelling insects be completed quickly, but the diffusion range of the repellent can also be increased in cooperation with the fan blades, and the practicability is high.
