Electrical mosquito-repellent incense convenient for long-time using in ventilation environments with doors and windows opened

Abstract

The invention discloses electrical mosquito-repellent incense convenient for long-time using in ventilation environments with doors and windows opened. The incense includes a base, a cylinder shell and a top cover; an electric heating rod is installed on the top cover, and the top cover is provided with multiple air vents for dissipating the mosquito-repellent gas formed by the evaporation of electrical mosquito-repellent incense liquid; concentration sensors and a controller are installed on the top cover; the cylinder shell is provided with an insulation sleeve made of a heat insulation material; the electric heating rod is located inside the insulation sleeve; the sidewall of the insulation sleeve is provided with multiple liquid flowing holes for the electrical mosquito-repellent incense liquid to flow; a stirring fork is arranged in the insulation sleeve; and a motor for driving the stirring fork to rotate around the electric heating rod is installed inside the base. The incense can guarantee the concentration of the mosquito-repellent gas to adapt to the air flowing conditions in ventilation environments with doors and windows opened, so that mosquito-repellent effects can beguaranteed, and the mosquito-repellent gas can be avoided from damaging human bodies due to excessive concentration; the incense is shorter in starting effective time and more convenient for long-time using, so that various defects of existing electrical mosquito-repellent incense can be overcome; and the incense is simple and reasonable in structure and convenient for promotion and using.

Description

technical field [0001] The invention relates to the field of electric mosquito-repellent incense, in particular to an electric mosquito-repellent incense which can be used for a long time in an open and ventilated environment with doors and windows. Background technique [0002] There are many types of electric mosquito-repellent incense, among which liquid electric mosquito-repellent incense is the most widely used one. The principle is to heat the electric mosquito-repellent liquid through electric heating elements such as electric heating rods, so that the electric mosquito-repellent liquid evaporates to form mosquito repellent gas, which is distributed to The effect of repelling mosquitoes can be achieved after being in the air. However, the mosquito repellent gas formed by the volatilization of electric mosquito-repellent incense liquid has certain harm to the human body. If the electric mosquito-repellent incense is used in a closed environment with doors and windows c...
