Description

Technical Field

[0001] The utility model relates to the technical field of mosquito monitoring, in particular to a self - suction type mosquito density monitoring device. Background Technique

[0002] Mosquito density monitoring is the basis for the early warning, prevention of mosquito - borne infectious diseases and mosquito control, and also the basis for evaluating the effect of mosquito control. Self - suction type mosquito density monitoring may refer to using self - suction devices or tools to monitor mosquito density, such as electric mosquito suckers, etc. According to the activity habits of local mosquitoes, the peak period of mosquito stinging is selected for monitoring. At the selected monitoring point, an electric mosquito sucker is used to continuously capture mosquitoes within a predetermined time period (such as 30 minutes), the captured mosquitoes are collected into a container, and then classified and counted. According to the number of captured mosquitoes and the monitoring time, the mosquito density is calculated.

[0003] In an electric mosquito sucker disclosed in the existing patent publication number CN210299178U, it consists of a battery, a battery housing, a fan, a motor, a motor housing, a partition net, a suction pipe, and a suction head. The battery is placed inside the battery housing, the fan is located at the rear end of the motor housing, the fan is connected to the motor through a wire, the battery housing is located below the motor housing and is connected through a threaded port. The front end of the motor housing and the rear end of the suction pipe are connected through a threaded port. The partition net corresponds to the bayonet inside the rear end of the suction pipe through a card slot to fix the partition net at the rear end of the suction pipe. The front end of the suction pipe is directly bent and transitioned to the rear end of the suction head; on the basis of maintaining stable electric suction, the shape of the suction head is improved to prevent mosquitoes from escaping, and at the same time, the transparency of the suction head is improved to avoid fragility.

[0004] When the above - mentioned device is in use, it can automatically suck mosquitoes, and then the mosquitoes in the suction head can be taken out after disassembly. However, when disassembling, the partition net lacks fixation, and when the suction head is disassembled, the partition net drops, which affects the collected mosquitoes and is not conducive to the subsequent density monitoring work, so improvement is needed. In view of the above problems, a self - suction type mosquito density monitoring device is proposed. Content of the Utility Model
