Mosquitoes are the bloodsucking insects that people hate most in summer. The invention of mosquito-repellent incense greatly reduces the harassment of people by mosquitoes. However, there is currently no Timing mosquito coils. Once lit at night, the whole mosquito-repellent incense will burn out, wasting a lot of mosquito-repellent incense. Mosquito-repellent incense divides the mosquito-repellent incense into 25 compartments, each compartment can burn for 10 minutes and can be selected according to the required mosquito-repellent incense time, thus greatly reducing unnecessary waste of the mosquito-repellent incense.
