The working principle is as follows: according to the invention, by arranging the first sliding groove 4, the flexible plate 5 and the memory spring 6, when the temperature inside the shell 1 is lower, heat dissipation operation is not needed, at the moment, the memory spring 6 is in an extension state, the flexible plate 5 is positioned inside the heat dissipation port 3 and seals the heat dissipation port 3, external dust and other sundries are prevented from entering the shell 1 through the heat dissipation port 3, the problem that the electric energy meter 2 is polluted is reduced, when the temperature inside the shell 1 is higher, heat dissipation needs to be carried out timely, the memory spring 6 is shortened after being heated, the flexible plate 5 is pulled upwards and taken into the first sliding groove 4, the heat dissipation port 3 is in an open state, the heat inside the shell 1 can be dissipated outwards through the heat dissipation port 3, the operation enables the heat dissipation port 3 to be automatically switched to a closed/open state, so that the double functions of pollution prevention and heat dissipation are achieved, and the practicability of the electric energy meter 2 is improved; when the temperature in the shell 1 is high, the memory spring 6 is heated and then shortens and pulls the flexible plate 5 upwards, and then the flexible plate 5 pulls the grid plate 8 into the heat dissipation port 3, so that the grid plate 8 can play a dustproof role, external dust and other impurities can be still prevented from entering the shell 1 when the heat dissipation port 3 is opened, and the problem that the electric energy meter 2 is polluted is further reduced; by arranging the arc-shaped convex block 9 and the arc-shaped elastic sheet 10, in the process of pulling the grid plate 8 up and down by the flexible plate 5, the arc-shaped convex block 9 can be in contact with the arc-shaped elastic sheet 10, and then the arc-shaped convex block 9 extrudes and deforms the arc-shaped elastic sheet 10, at the moment, the movement resistance of the grid plate 8 is increased, when the arc-shaped convex block 9 crosses the middle part of the arc-shaped elastic sheet 10, the movement speed of the grid plate 8 can be increased in a short time, so that the movement of the grid plate 8 has a pause effect and continuously shakes, impurities in the grid plate 8 shake off, and the problem that the heat dissipation efficiency is reduced after the grid plate 8 is blocked by the impurities is avoided; through the arrangement of the mounting box 11 and the drying box 12, the drying agent in the drying box 12 can be in contact with the air in the shell 1 through the moisture absorption port 13, so that moisture in the air is absorbed, the interior of the shell 1 is kept dry, the problem of abnormal work caused by the fact that the electric energy meter 2 is wetted is solved, after the drying agent fully absorbs moisture, the drying box 12 is pulled out, a new drying agent is replaced, and the drying box 12 is pushed into the mounting box 11 again; after the drying agent is replaced, the drying box 12 is pushed into the installation box 11 again, at the moment, the first magnet 15 and the second magnet 17 attract each other, when the subsequent grid plate 8 moves upwards, the second magnet 17 can be synchronously moved upwards through the first pull rope 14 and the first magnet 15, the second magnet 17 further upwards pulls the second pull rope 22, the second pull rope 22 is simultaneously wound on the surfaces of the plurality of winding wheels 21, the second pull rope 22 can pull the plurality of winding wheels 21 to synchronously rotate, the winding wheels 21 drive the rotating disc 19 and the blades 20 to rotate, the blades 20 further pull the surrounding drying agent, and the drying agent in the drying box 12 is turned over, so that the utilization rate of the drying agent is improved, the drying agent can absorb more moisture, the replacement times of the drying agent are reduced, and when the subsequent grid plate 8 moves downwards, the winding wheels 21 and the rotating disc 19 rotate and reset under the action of the torsion spring; in the process that the turntable 19 rotates outside the fixed rod 18, when the guide ball 27 and the magnetic block 23 approach each other, the magnetic block 23 attracts the guide ball 27, so that the guide ball 27 drives the elastic membrane 25 to dent towards the bottom of the groove 24, and further pulls and deforms the elastic membrane 25, when the guide ball 27 rotates to a position far away from the magnetic block 23, the attraction of the magnetic block 23 to the guide ball 27 disappears, and further the elastic membrane 25 rebounds outwards under the action of the elasticity of the elastic membrane 25 to reset, so that the drying agent on the surface of the elastic membrane 25 is thrown outwards and impacts the surrounding drying agent, the problem of agglomeration of the drying agent after being wetted is reduced, more moisture can be absorbed by the drying agent, and the utilization rate of the drying agent is further improved; when the magnetic block 23 attracts the guiding ball 27, the guiding ball 27 extrudes and deforms the elastic sheet 29 and then enters the combining groove 28, the guiding ball 27 is pulled outwards when the subsequent elastic film 25 rebounds and resets, so that the guiding ball 27 separates from the combining groove 28 after extruding and deforming the elastic sheet 29, the force of the elastic film 25 rebounds can be improved, the outward throwing speed of the drying agent is increased, the crushing effect on the lump-shaped drying agent is improved, and the utilization rate of the drying agent is further improved.
