Negative pressure type insect sampler and working method thereof

Abstract

The present invention discloses a negative pressure type insect sampler and a working method thereof. The negative pressure type insect sampler comprises a negative pressure device; the negative pressure device and a handle are connected; the inside of the handle is provided with a rechargeable battery, a turbo fan and a cyclone accelerator; the negative pressure device comprises an air inlet assembly; the air inlet assembly and an air guide cylinder are connected; the other end of the air guide cylinder is detachably connected with an insect storage device. The negative pressure type insect sampler is designed based on today's most advanced fanless fans, and strong and soft in wind power, avoids insect scales and limbs being destroyed, and maintains intact appearance of the insect; a folding door is arranged in the insect storage device and can be opened and closed; the end of the insect storage device is a closed net, and is breathable and can effectively prevent insects from escaping; a carrier is arranged in a screw cover and used for accommodating anesthetics; an anesthetic treatment can be performed on the spot; and the negative pressure type insect sampler greatly improves the insect catching efficiency, has a simple structure, and is convenient to use and relatively strong in practicality.

Description

technical field [0001] The invention relates to the technical field of plant protection devices, in particular to a negative pressure insect sampler and its working method. Background technique [0002] As we all know, mosquitoes feed on blood and can transmit malaria, yellow fever, chikungunya fever, dengue fever, Zika and other infectious diseases that seriously endanger human health, and have caused many large-scale deaths in human history , is one of the deadliest vector organisms. In order to suppress the spread of the disease, humans capture or kill the insects in various ways, such as mosquito suckers and mosquito killer lamps. [0003] Most of the existing mosquito suckers are designed on the basis of small fans with blades, and axial flow fans are mostly used. The basic principle is that the blades have an inclination angle. When the blades rotate, they must overcome the air resistance to do work, so The air obtains kinetic energy to generate movement, and its kin...

Problems solved by technology

However, the air source part is equipped with fan blades, which makes the noise louder during use, which may easily cause insects to become alert, thereby reducing the trapping rate. In addition, the fluke mouth is small and the wind direction is fixed, which is not conducive to trapping insects. The function is single and inconvenient follow-up work
