Trapping device for fly insects

Abstract

The invention discloses a trapping device for fly insects, which comprises a working shell, a bait smell generating device and a vacuum suction device, wherein an insect suction inlet and a bait smell discharging port are arranged on the working shell; an insect trapping chamber is arranged on the working shell and is communicated with the insect suction inlet; the bait smell discharging port is communicated with the bait smell generating device; the vacuum suction device is arranged on the working shell and supplies a suction force for sucking the insects enticed by the bait smell from the insect suction inlet; the bait smell generating device comprises a bait jar; an attractant source for heating and decomposing the bait smell is stored in the bait jar; a heating element is arranged on the bait jar; and a bait smell outlet of the bait jar is communicated with the bait smell discharging port. The trapping device for the fly insects not only can effectively trap and kill the fly insects but also is low in cost, is convenient to maintain and is wide in use scope. Compared with the present trapping device, the trapping device for the fly insects is more suitable for household.

Description

technical field [0001] The present invention relates to a trapping device for flying insects, in particular to a trapping device for trapping harmful flying insects attracted by odor or other attracting elements emitted by mammals. Background technique [0002] At present, the main methods for the prevention and control of some harmful insects (mainly mosquitoes that bite people) include conventional methods such as killing insecticides, repelling insect repellents, and killing mosquitoes by electric lamps. The disadvantages of these conventional methods are obvious. Insecticides The harm to people and animals and the permanent damage to the environment are very serious. Insect repellents only drive away harmful mosquitoes, but cannot effectively control the number. The effect of mosquito killer lamps is also very limited, only for a small number of phototaxis mosquitoes. efficient. Patent CN1564656A discloses a method of using combustion to generate carbon dioxide gas to l...

AI Technical Summary

Problems solved by technology

However, this combustion method has high requirements on the purity of gas. In our country, the problem of acclimatization is encountered. The burner must be cleaned every month. The cost of labor and consumables seriously affects the promotion of its technology.

The patent CN201178641Y discloses a device that directly uses cheap industrial carbon dioxide gas to attract and kill mosquitoes, but the main attractant carbon dioxide required by this patent needs to be filled with high-pressure gas cylinders, and ordinary families do not have such high-pressure gas cylinders. , it is very troublesome when supplementing the carbon dioxide gas source, therefore, it also seriously affects the popularization of this product to household use
