Anti-escape device of flying insect trap

Abstract

The invention belongs to the technical field of insect trap tools, and particularly relates to an anti-escape device of a flying insect trap. The invention discloses the anti-escape device of the flying insect trap, which comprises an anti-escape box body. An air inlet is provided at the top end of the anti-escape box body, an inverted-V shaped fish mouth type air direction converting device is provided in the anti-escape box body and under the air inlet, and an air outlet is provided on two sides of the anti-escape box body corresponding to the fish mouth type air direction converting device, and a movable anti-escape door capable of plugging up the air outlet is arranged on the anti-escape box body. The inventive anti-escape device can completely solve the defects of poor anti-escape effects of anti-escape devices such as funnel type and offset axis type anti-escape door (rocker plate type) and turnover plate type anti-escape plate.

Description

technical field [0001] The invention belongs to the technical field of insect traps, in particular to an anti-escape device of a flying insect trap. Background technique [0002] Flies, mosquitoes, moths, beetles and other flying insects often affect people's lives and are environmental pests that seriously endanger human health. Using traps (machines) to trap and kill them is one of the important means to reduce their harm. It is also the most environmentally friendly and economical killing method commonly used by people. In the past few decades, in order to eliminate flying insects such as mosquitoes, flies, and moths, people have invented electric shock type mosquito traps and sticky type mosquito traps. Yet these traps are unsatisfactory to the killing effect of mosquito, fly, moth etc. in the course of use, because attracting source is single or unreasonable in design. At present, there are multiple upright sucking mosquito, fly, and flying insect trapping devices on ...

AI Technical Summary

Problems solved by technology

But there are many defects in these anti-escape devices, such as the funnel type anti-escape device, when the outlet is small, it is easy to be blocked by flying insects, and when the outlet is too large, it is easy for flying insects to escape.

Off-axis anti-escape doors (rocker type), flip-type anti-escape panels and other anti-escape devices lose their anti-escape function due to the failure of the parallel axis due to the adhesion of flying insect corpses during use
