Description

Technical Field

[0001] This utility model belongs to the field of adult mosquito live collection tools, specifically relating to an adult mosquito live collection device. Background Technology

[0002] The collection of live adult mosquitoes is the cornerstone of mosquito morphological identification, research on mosquito-borne infectious diseases, mosquito ecological biology, and mosquito-borne disease control systems. It ensures the integrity and authenticity of the external morphological characteristics of the collected biological samples, enabling subsequent entomological, pathogenic, and genetic analyses, ultimately leading to more precise early warning, more effective interventions, and more cutting-edge scientific research.

[0003] Currently, common methods for collecting live adult mosquitoes include mosquito-attracting lamps with collection boxes, adhesive traps, and handheld electric mosquito aspirators. Mosquito-attracting lamps use ultraviolet light or specific wavelengths to attract mosquitoes. Once inside the collection box, the mosquitoes are trapped and easily die from dehydration. Furthermore, their collection efficiency is easily affected by external light source conditions, lamp placement, and the operator's experience, resulting in poor stability. Adhesive traps capture mosquitoes using sticky materials. While simple in structure, the trapped mosquitoes rarely survive, failing to meet the requirements for live experiments. They also pose a risk of sample contamination, affecting subsequent pathogen detection or gene sequencing results. Utility Model Content

[0004] In view of the problems existing in the background technology, this utility model proposes a live adult mosquito collection device to improve collection efficiency, while reducing mosquito survival rate and facilitating transfer and subsequent research.

[0005] The present invention relates to a live adult mosquito collection device, comprising a collection box and a lid that covers the collection box. The box lid is equipped with an air inlet pipe that passes through the lid and extends into the collection box. Its air outlet is flush with the inner surface of the lid, and a check valve is installed near the air outlet. A branch of the air inlet pipe is connected to a mosquito inlet, and a fan is installed at the air inlet. A mosquito cage is installed inside the collection box. The top of the mosquito cage is magnetically connected to a cage lid, and the bottom is equipped with a water-soaked sponge to maintain humidity. A soft sleeve is connected to the side, and the sleeve extends out of the box through an air outlet on the side wall of the collection box. A through hole is also opened in the side wall of the collection box. A cover plate is hinged to the inside of the through hole. The cover plate is connected to the inner wall of the collection box by a spring. When no external force is applied, the cover plate closes to seal the through hole.

[0006] The lid is fastened to the collection box by a snap fastener, and a sealing strip is provided at the joint between the lid and the collection box.

[0007] The bottom of the mosquito cage has a pair of slots, and the slots are filled with water-soaked sponges.

[0008] The beneficial effects of this utility model are: Compared with existing technologies, this invention places the fan at the front, which provides negative pressure to draw adult mosquitoes in through the mosquito inlet. Furthermore, by optimizing the air inlet pipe structure, the air outlet is horizontally positioned and flush with the inner surface of the cover, preventing direct airflow impact on the bottom of the collection box and effectively reducing mechanical damage to the mosquitoes. A check valve is also included to prevent mosquitoes from escaping backflow. A water-soaked sponge is placed at the bottom of the mosquito cage to maintain humidity, significantly reducing mosquito dehydration mortality and ensuring sample survival. The design of the through-hole, spring, and cover plate ensures airtightness while facilitating cage cover installation. Finally, the mosquito cage can be completely removed, enabling non-destructive transfer and batch processing. The overall device has good sealing performance, is easy to operate, and can efficiently collect live adult mosquitoes while maintaining sample morphology and biological activity, facilitating subsequent morphological identification, pathogen detection, and genetic analysis.

Detailed Implementation

[0015] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding by those skilled in the art.

[0016] Example 1 See Figures 1 to 5 The illustrated adult mosquito live collection device includes a collection box 1 and a box cover 2.

[0017] The lid 2 is installed on the collection box 1 via a snap fastener 9. To improve the sealing performance, a sealing strip can also be installed on the lid 2 to fit tightly against the collection box 1.

[0018] An air inlet pipe 202 is provided on the cover 2, which passes through the cover 2 and extends into the collection box 1. The outlet end of the air inlet pipe 202 is located inside the collection box 1 and is flush with the inner surface of the cover 2 to avoid the airflow directly impacting the bottom of the box. A check valve 6 is installed near the outlet end of the air inlet pipe 202. The check valve 6 is a magnetic valve used to prevent mosquitoes from escaping backflow. A branch of the air inlet end of the air inlet pipe 202 is connected to a mosquito inlet 203, and a fan 5 is provided at the air inlet end. The fan 5 provides negative pressure suction. The mosquito inlet 203 is used to attract and guide adult mosquitoes. The fan 5 and the mosquito inlet 203 are not in a straight line, so that the mosquito inlet 203 can cover the mosquitoes during collection.

[0019] To facilitate the overall transfer of the collection box 1, a handle 201 is also provided on the lid 2.

[0020] Inside the collection box 1 is a suitable mosquito cage 3. The top of the mosquito cage 3 has a cage cover 4 that is magnetically attached, and the bottom has a pair of slots 302 for placing a water-soaked sponge 10 to maintain humidity inside the cage, thereby reducing the dehydration and death of adult mosquitoes and facilitating subsequent transportation. A soft sleeve 301 is provided on one side of the mosquito cage 3. The sleeve 301 extends out of the box through the air outlet 102 on the side wall of the collection box 1 and can be sealed by binding or clamping.

[0021] The collection box 1 has a through hole 101 on the other side wall. The inside of the through hole 101 is connected to a cover plate 7 by a hinge. The cover plate 7 is connected to the inner wall of the box by a spring 8. Under the action of no external force, the cover plate 7 is kept closed by the tension of the spring 8, sealing the through hole 101.

[0022] In use, place the mosquito cage 3 in the collection box 1, with the sleeve 301 extending out of the air outlet 102 and secured. Turn on the fan 5; mosquitoes are sucked into the mosquito inlet 203, enter the collection box 1 through the air inlet pipe 202, and fall into the mosquito cage 3. After collection, turn off the fan 5; the check valve 6 prevents mosquitoes from escaping backflow. The operator pushes the cage cover 4 through the through hole 101, pushes open the cover plate 7, magnetically connecting the cage cover 4 to the mosquito cage 3. Finally, open the box cover 2 and remove the mosquito cage 3 along with the sleeve 301, completing the transfer of live adult mosquitoes. This device allows for continuous replacement of the mosquito cage 3 as needed, achieving efficient, non-destructive, and large-scale adult mosquito collection.

[0023] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
