Description

Cyclone insect trap

The present invention relates to an insect trapping device, in particular to an insect trapping device capable of actively attracting mosquitoes and culling the induced mosquitoes through a cyclone.

Comfortable and clean living environment is the goal pursued by modern people. However, in today's living environment, there are many insect organisms that are harmful to the environment and human health, such as mosquitoes, flies, etc. Among them, flies like corrupt food, and It will stick the harmful substances on the corrupted food to another item, thus making the flies become a medium for spreading diseases, which will bring a lot of infectious diseases to human beings. On the other hand, mosquitoes will not only bite and suck human blood, but also cause human skin to produce. Redness and itching, and even many diseases such as dengue fever and malaria are transmitted through mosquitoes as a medium, which in turn poses a great threat to people's lives.

In order to prevent the mosquitoes from transmitting the virus to humans, there are many products on the market that have eliminated mosquitoes, such as flycatchers, fly-catching papers, insecticides and mosquito coils. However, flycatchers and fly-papers The method of trapping mosquitoes will cause the bodies of the mosquitoes to be exposed to the environment, which will not only hinder the observation and even affect the sanitation. Among them, after the fly paper is used for a period of time, the fly paper will be dusty and dirty due to the air. It reduces the viscosity and gradually loses the effect of catching mosquitoes. Therefore, in order to prevent the flytrap from catching the mosquitoes, it is necessary to replace the new fly papers. However, often changing the fly paper will cause resources. Waste, in addition, insecticides and mosquito coils rely on gas to achieve the effect of culling or repelling mosquitoes. However, the gases produced by insecticides and mosquito coils can also adversely affect human health and cause environmental problems. Many manufacturers are constantly developing innovative mosquito traps.

At present, mosquito traps are commonly used as insect traps and insect traps. Among them, the traps use the phototaxis of mosquitoes and set up a power grid layer around the lamp tube to make the mosquitoes fly toward the tube and touch the power grid layer. The electric current is used to kill mosquitoes by electric shock, and although the method of killing mosquitoes has certain effects, the mosquito traps have the defects of power consumption and safety concerns in use, and the insect traps are internally placed. The bait and the liquid that can quickly kill the mosquito, and the insect trapper allows the mosquito to enter the insect trap through the bait, and then the mosquito is culled through the liquid. However, when the insect trap is actually used, the liquid is easily overturned and exposed. Causes environmental pollution and difficulties in cleaning up.

The main purpose of this creation is that when the fan is in operation, worms are generated inside the insect trap, so that the mosquitoes attracted by the attracting device are sucked into the trap, and the vortex can carry the mosquitoes inside the trap. It is air-dried, and the mosquitoes die because they are dried, which can effectively achieve the effect of eliminating mosquitoes.

The secondary purpose of this creation is to ensure that mosquitoes do not fly out of the interior of the insect trap to the outside of the insect trap before the mosquito is killed by air.

Another purpose of this creation is that the fan blades can avoid the accumulation of excessive mosquitoes and dust in the long-term operation of the fan, thereby increasing the service life of the fan.

In order to achieve the foregoing objectives, the present invention relates to a cyclone type insect trap device mainly comprising an insect trap container, a fan, an attracting device, an anti-escape member and a mosquito killing device.
