Laser mosquito repelling equipment

Abstract

The invention provides laser mosquito repelling equipment and belongs to the technical field of mosquito repelling. According to the technical scheme, the equipment comprises a rotating mechanism, wherein a protective cover is arranged on the rotating mechanism; a laser emitting mechanism is arranged in the protective cover; a laser collimating lens in the laser emitting mechanism collimates a laser emitted by a semiconductor laser device; a collimated laser beam forms a pulse laser scanning area outside the protective cover through a laser rotating reflecting mirror; the laser collimating lens changes a focal length value by changing a power supply signal to achieve laser mosquito repelling in different distances. The laser mosquito repelling equipment has the advantages that the focal length value is changed by changing the power supply signal, correspondingly mosquitoes cannot normally utilize the sensory organs to search for a blood suction target, and therefore an optimal mosquitorepelling effect is achieved. Compared with a conventional laser mosquito killer, the equipment has the advantage of requiring no mosquito positioning devices; the rotating mechanism can drive the protective cover and the laser emitting mechanism in the protective cover to rotate, mosquito repelling can be performed at the angle of 360 degrees, and the mosquito repelling range is wider.

Description

technical field [0001] The invention relates to the field of mosquito repelling technology, in particular to a laser mosquito repelling device. Background technique [0002] The head of the mosquito is hemispherical, with a pair of compound eyes, a pair of antennae, and a beak. The antennae have 15 segments: the first segment is called the stalk segment, the second segment is called the peduncle segment, and each segment after the third segment is elongated and called the whip segment. Each flagellum grows a ring of hairs, the whorls of female mosquitoes are short and sparse, and the whorls of male mosquitoes are long and dense. On the antennae of female mosquitoes, in addition to the round hairs, there is another type of short hairs distributed on each flagellum. These short hairs respond to changes in chemical substances in the air, especially to compounds such as carbon dioxide and lactic acid and humidity. It is sensitive, and it is the short hairs, not the compound ey...

Problems solved by technology

How can we effectively repel mosquitoes? Existing mosquito repellent products generally use odorants to disturb the sense of smell of mosquitoes, or use ultraviolet light to visually trap and kill mosquitoes, etc., which cannot achieve a good mosquito repellent effect

[0005] Existing laser mosquito killers use sound or images to locate mosquitoes in flight, and then emit laser light to irradiate the wings of mosquitoes to shoot them down. This requires high laser power and requires functions such as radar or sound positioning, which is expensive. , cannot be popularized
