Dual-purpose portable mosquito repellant

Abstract

The invention relates to a mosquito repelling device, in particular to a mosquito repellent which can be used both indoors and outdoors and is portable, comprising a miniature DC motor driven by cells and a power source switch; a slow-releasing agent mosquito repelling tablet is placed within a bracket a central hole axis of which is matched with a miniature DC motor shaft tightly, the bracket isprovided with a top ring which is provided with a clipping board stretching inwards, and a support rib extending radially around the central hole axis is bent upwards to be connected with the bottom surface of the top ring. The invention gradually releases the agent odor by means of the high speed rotation of the slow-releasing mosquito repelling tablet in the bracket driven by the miniature DC motor, and the high speed rotation of the bracket and the slow-releasing mosquito repelling tablet generates an airflow to spread the mosquito repelling odor around along with the airflow to realize the objective of repelling the mosquito. The mosquito repellent is small in volume and convenient in being taken outside, the power of the electric motor thereof is only used for the rotation of the bracket and the slow-releasing mosquito repelling tablet, which means the power consumption is low and service time of the cells is long; the mosquito repellent can be directly powered by commercial power for working when used in the room, and the tablet can be changed only by opening the lid, which brings easiness and convenience.

Description

technical field [0001] The invention relates to a mosquito repellent device, in particular to an indoor and outdoor mosquito repellent which is easy to carry around. Background technique [0002] At present, electric heating mosquito repellents are usually used indoors, which consumes relatively large power; while outdoors, due to the lack of AC power supply, electric heating mosquito coils cannot be used, and burning mosquito coils have to be used, which poses a fire hazard. If the mosquito repellent sheet is heated by battery electric energy and is converted into portable use, the service life of the battery is extremely short and lacks economy. Chinese patent 03259315.5 discloses a mosquito repellent utilizing slow-release medicaments, including a miniature DC fan, a battery, a control circuit and a mosquito repellent kit. The air outlet and the other airflow channel are the air outlet, which generates airflow through the operation of the micro DC fan, so that the slow-r...

Problems solved by technology

The defective that the mosquito repellent of this structure exists, the one, micro direct current motor drives fan blade, and mosquito repellent medicine box is fixed, and makes rectangular box body, and volume is relatively large, and cost is high, and portability is not ideal yet; It can only be placed flat, and the air outlet is aimed at the human body, the direction is limited, and if it is placed too far, the mosquito repellent effect will be weakened, if it is placed too close, the mosquito repellent range will be reduced, and a small beam of wind blowing on a certain part of the human body for a long time will feel uncomfortable
