How to use electric mosquito-repellent incense and mosquito-repellent incense tablets?

Tear off the wrapping paper, take out the fragments, insert the electric mosquito repellent incense device and electrify it. All right. Under the iron sheet in the middle of the mosquito-repellent incense device is a heating ceramic sheet, which is heated after being electrified and baked to make the medicine emit. Mosquito repellent incense is a tool to repel mosquitoes. The harm of electric mosquito-repellent incense is the same as that of mosquito-repellent incense: the active ingredients of disc, liquid and electric mosquito-repellent incense are all chemical preparations containing insecticidal ingredients, and the only difference is that their carriers are different. Therefore, it is unscientific to say that smokeless mosquito-repellent incense is less harmful than smoked mosquito-repellent incense, and that electric mosquito-repellent incense is less harmful than disc-type mosquito-repellent incense.
