When the switch 302 and the router 303 work, heat is generated, when the heat in the case 1 is insufficient to dissipate heat through the heat dissipation groove 101, so that the temperature in the case 1 is higher, when alcohol in the liquid storage cavity 203 in the control box 202 is heated and volatilized, the air pressure in the liquid storage cavity 203 is increased, then the volatilized and gasified alcohol pushes the sliding plate 204 to move downwards, and compresses the first spring 205, meanwhile, the sliding plate 204 drives the first conductive sheet 206 to move downwards synchronously, and further the first conductive sheet 206 is in contact with the second conductive sheet 207, the suction pump 2 is started, the suction pump 2 absorbs external air through the first pipeline 201 and the heat dissipation groove 101, the air is in contact with the activated carbon filter screen 102 when passing through the heat dissipation groove 101, and because of a developed void structure and rich micropore tissues in the activated carbon, the micropore tissues have strong adsorption force fields, when the air is in contact with the activated carbon, particles in the air can be adsorbed into the micropores, so as to achieve the effect of purifying the air, then the purified air enters the case 1 through the heat dissipation groove 101, and then the air drives the heat in the case 1 to flow out of the first pipeline 201 and the heat dissipation groove 101, the air can flow out of the case 1 and the air through the heat dissipation groove 101, so that the effect of the case 303 can be increased;

then, when the temperature inside the case 1 decreases and the volatilized alcohol in the liquid storage cavity 203 cools and liquefies, the air pressure inside the liquid storage cavity 203 decreases, so that the compressed first spring 205 generates a pushing force to push the sliding plate 204 to drive the first conductive sheet 206 to move upwards, so that the first conductive sheet 206 is separated from the second conductive sheet 207, and at this time, the getter pump 2 is automatically turned off.

The above description is only of the preferred embodiments of the present invention, and is not intended to limit the present invention in any way, although the present invention has been described in the preferred embodiments, and is not limited thereto.
