Wind speed adjustable electric mosquito suction device

Abstract

The invention discloses a wind speed adjustable electric mosquito suction device. A control module of the wind speed adjustable electric mosquito suction device comprises a variable-speed regulating circuit and a variable-speed regulating switch and is used for regulating the wind speed of a power module; a suction head part is divided into a suction head part and a connecting part, the connectingpart is connected to a power module through a filter screen structure, the outer diameter from the suction head part to the connecting part is evenly increased to form a conical structure, the suction head part is provided with a funnel-shaped pipeline structure extending towards an inner cavity of the suction head, and the pipeline structure and the side wall of the suction head part form a mosquito storage bin; and a through hole sealed by a gauze element is formed in the front end face of a suction head cover. According to the wind speed adjustable electric mosquito suction device, the mosquito catching rate is high, the mosquito damage rate is low, and mosquitoes can be effectively prevented from escaping.

Description

technical field [0001] The invention relates to the field of biological sample collection tools in the prevention and control of vector diseases, in particular to an adjustable wind speed electric mosquito suction device. Background technique [0002] Mosquitoes are currently the most important medical insect populations in the world. In addition to harassment caused by blood-sucking bites, they can also be used as the most important biological vectors to transmit diseases including dengue fever, malaria, Japanese encephalitis, chikungunya and yellow fever. multiple infectious diseases. Mosquito monitoring, detection and other research are inseparable from mosquito sampling. At present, the most used adult mosquito sampling is the portable electric mosquito suction device. Many methods of adult mosquito monitoring (such as human trapping method, animal trapping method, roosting mosquito trapping method, net trapping method and black box method, etc.) all involve electric mo...

Problems solved by technology

[0003] But there are many shortcomings in the electric mosquito suction device commonly used at present: 1) electric mosquito suction device adopts the wind speed of medium uniform speed more, although this wind speed has reduced the physical damage of high-speed airflow to mosquito, mosquito capture efficiency is low, promptly catches the instantaneous wind force of mosquito. Insufficient and easy to cause mosquitoes to escape; 2) When there are mosquitoes in the mosquito storage tube, when other mosquitoes are caught again, the open suction port is easy to cause the existing mosquitoes to take the opportunity to escape; When opening, turn on the fan first, and then open the cover, and at the moment when the fan is opened and the cover is not opened, a strong turbulent flow will be formed in the mosquito storage tube, causing the mosquitoes in the mosquito storage tube to rub against the tube wall with the turbulent flow, causing mosquito damage. Severe cases will cause limb damage or damage identification features. After the mosquitoes are captured, cover the cover and the fan is still running, and there will be obvious turbulent flow; 4) The mosquito storage tube is mostly made of non-transparent material, which is not easy to observe the mosquitoes in the mosquito storage tube 5) When there are many mosquitoes, the usual method is to keep the fan running continuously, and the mosquitoes in the mosquito storage tube will be sucked into the bottom of the mosquito storage tube under the action of the air flow, forming multiple frictions, and it is also easy to lose weight for a long time. death from dehydration
