Portable mosquito repelling/fragrance device

Abstract

The invention discloses a portable mosquito repelling / fragrance device. The portable mosquito repelling / fragrance device comprises a shell, a repellent / essential oil pot, an electric heating atomizer, a battery and an air pump. The portable mosquito repelling / fragrance device is characterized in that the repellent / essential oil pot is connected with the electric heating atomizer through a siphon, the electric heating atomizer is connected with the air pump in a controlling mode through a circuit board, a power line of the atomizer and a power line of the air pump are connected to a pulse power supply switch, and the pulse power supply switch is controlled through a switch in the circuit board. A control method of the portable mosquito repelling / fragrance device is characterized in that the circuit board starts a pulse power supply through a control switch so that the pulse power supply can be supplied to the atomizer and the air pump. The portable mosquito repelling / fragrance device has the advantages that the rapid mist (repellent / essential oil) forming-intermittent releasing-rapid spreading method is adopted, the smell released by the portable mosquito repelling / fragrance device is pulsatile instead of constant, and the phenomenon of smell fatigue caused by an existing mosquito repelling / fragrance device can be effectively avoided as long as the frequency is proper. By the adoption of the control method of the portable mosquito repelling / fragrance device, power consumption can be reduced greatly.

Description

technical field [0001] The invention relates to a portable mosquito repellent / aroma diffuser. Background technique [0002] Mosquitoes have a keen olfactory system, which can distinguish the carbon dioxide gas exhaled by mammals within 30 meters; on the contrary, they have long been aware of the smell they don't like. If there is an odor that it does not like to dominate in a certain area, the mosquito will not enter. All mosquito repellents take advantage of this feature. [0003] Traditional mosquito repellents (including electric mosquito coils, liquid mosquito coils, mosquito repellent patches, mosquito repellent bracelets, etc.) achieve the purpose of repelling mosquitoes through the volatilization of repellents (a solid / liquid collective name that produces mosquitoes’ unpleasant smell) within the effective range. . The volatilization per unit time of the same type of repellent determines the mosquito repellent effect. [0004] Electric mosquito coils and liquid mos...

Problems solved by technology

But heating needs to consume 6-10W electric power, which is only suitable for places with mains electricity, and it is impossible to be portable; while portable mosquito repellent devices such as mosquito repellent stickers and mosquito repellent bracelets only rely on the natural volatilization of repellents, so the mosquito repellent effect It is weak, and the effective time is only 2-3 hours, which is difficult to meet the demand; people have such experience: they can smell the fragrance of the essential oil in the device when entering the closed compartment for the first time, but as long as they enter the compartment for a few minutes, although the fragrance is still there Survival, I really can't smell the smell just now, this is "olfactory fatigue"
