Description

Technical Field

[0001] This utility model relates to the field of mosquito trap technology, and in particular to a handheld negative pressure mosquito trap. Background Technology

[0002] Within the scope of customs work, airport ports and merchant ship containers are key areas. Airports serve as hubs for the rapid flow of people and goods, while merchant ships carry large quantities of international trade cargo. These areas are prone to infestations of disease-carrying organisms such as mosquitoes and flies, necessitating the use of handheld negative pressure mosquito traps. These traps are small, portable, and can be used by staff anytime, anywhere, without spatial or locational limitations. Mosquito control operations can be conveniently conducted in airport halls, boarding corridors, and even in various corners of merchant ships and inside containers.

[0003] Once a mosquito is spotted, the user quickly presses the start button on the mosquito trap, and the built-in negative pressure device immediately begins to work. Then, holding the mosquito trap close to the mosquito, the user aligns the mosquito-catching nozzle with the mosquito's flight path. Using the powerful negative pressure suction, the mosquito is instantly sucked into the sticky paper inside the mosquito trap, completing the capture.

[0004] In existing technologies, some handheld negative pressure mosquito traps require the separation of the tube from the negative pressure device using threads or bolts and tools when the sticky mosquito paper needs to be replaced. This process is cumbersome, and finding the tools, disassembling, and reassembling all take a lot of time, resulting in low efficiency in replacing the sticky mosquito paper and seriously affecting the frequency of use and work efficiency of the mosquito trap. Therefore, in order to address the above shortcomings, a handheld negative pressure mosquito trap is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a handheld negative pressure mosquito catcher, which aims to improve the problem that some existing handheld negative pressure mosquito catchers require threads or bolts with tools during use, making operation complicated, time-consuming and laborious.

[0010] As a further description of the above technical solution:

[0011] The drive assembly includes an opening block, the top side of which is fixedly connected to the bottom side of the guide tube, and an electric push rod is rotatably connected inside the opening block.

[0012] As a further description of the above technical solution:

[0013] The drive end of the electric push rod is rotatably connected inside the concave block, and the right ends of the two rotating plates are rotatably connected to the front and rear sides of the guide tube by pins respectively.

[0014] As a further description of the above technical solution:

[0015] The guide tube has cavities at both ends, and the interior of the cavities is slidably connected to the outside of the limiting ball.

[0016] As a further description of the above technical solution:

[0017] The two limiting posts have their adjacent ends slidably connected to the front and rear ends of the connecting ring, and their distant ends slidably connected to the front and rear sides of the inner wall of the sliding ring.

[0018] As a further description of the above technical solution:

[0019] The sliding ring is internally slidably connected to the outer wall of the guide tube, and the right side of the sliding ring is in contact with the left side of the support cylinder;

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] ReferenceFigures 2 to 4 This utility model provides an embodiment of a handheld negative pressure mosquito trap, comprising a support cylinder 1 made of engineering plastic, capable of withstanding external impact. A connecting ring 2 is fixedly connected to the left side of the support cylinder 1 via welding. A limiting ring 3 is slidably connected inside the connecting ring 2, allowing the connecting ring 2 to slide stably. A convex mosquito-adhesive plate 4 is fixedly connected inside the limiting ring 3, with glue evenly applied to the convex surface of the convex mosquito-adhesive plate 4. A guide tube 5 is slidably connected to the outside of the connecting ring 2, providing guidance for the guide tube 5 and facilitating installation. A positioning ring 6 is fixedly connected to the outside of the guide tube 5 via welding, providing support for the positioning ring 6. A spring 7 is fixedly connected to the right side of the positioning ring 6, ensuring the spring 7 receives uniform force. A sliding ring 8 is fixedly connected to the right side of the spring 7; during sliding, the sliding ring 8 compresses the spring 7, allowing the spring 7 to store elastic potential energy, which then applies a force in the opposite direction to the sliding ring 8 for resetting.

[0033] The sliding ring 8 is internally slidably connected to the outer wall of the guide tube 5, allowing it to slide stably. The right side of the sliding ring 8 contacts the left side of the support cylinder 1, improving the sealing effect and preventing air leakage. Push plates 9 are fixedly connected to both the front and rear sides of the sliding ring 8, facilitating user movement. Cavities 10 are formed inside both the front and rear ends of the guide tube 5, with protrusions on both sides. Limiting balls 11 are slidably connected to both the front and rear ends of the guide tube 5, allowing them to slide stably. The interior of the cavity 10 is slidably connected to the exterior of the limiting ball 11, preventing it from slipping. A limiting post 12 is fixedly connected inside the limiting ball 11, restricting it and preventing it from slipping. The adjacent ends of the two limiting posts 12 are slidably connected to the interiors of the front and rear ends of the connecting ring 2, engaging the connecting ring 2 by sliding the limiting posts 12 inside it. The two limiting posts 12 are slidably connected to the front and rear sides of the inner wall of the sliding ring 8, respectively. The sliding ring 8 abuts against the limiting posts 12, so that the limiting posts 12 can be engaged inside the connecting ring 2.

[0034] Reference Figures 1 to 3A drive assembly providing power is fixedly connected to the bottom side of the guide tube 5. The drive assembly includes an opening block 13, the top side of which is fixedly connected to the bottom side of the guide tube 5 by welding, thus providing stable support for the opening block 13. An electric push rod 14 is rotatably connected inside the opening block 13 to provide a drive source. A concave block 15 is rotatably connected to the left end of the drive assembly, and the drive end of the electric push rod 14 is rotatably connected inside the concave block 15, so that the concave block 15 is rotated by activating the electric push rod 14. A protective plate 16 is fixedly connected to the top side of the concave block 15, through which the rotational force is transmitted to the protective plate 16. A sealing ring 17, made of rubber, is fixedly connected to the right side of the protective plate 16 to fit the guide tube 5 for sealing.

[0035] Both ends of the protective plate 16 are rotatably connected to rotating plates 18 via pins. The right ends of the two rotating plates 18 are rotatably connected to the front and rear sides of the guide tube 5 via pins, respectively. The pins restrict the rotation of the rotating plates 18, allowing them to rotate around the pins on their right ends under the push of the protective plate 16. Connecting blocks 19 are fixedly connected to the upper and lower sides of the inner wall of the support cylinder 1 via welding, providing support for the connecting blocks 19. A motor 20 is fixedly connected to the adjacent side of the two connecting blocks 19, providing a drive source. Multiple fan blades 21 are fixedly connected to the drive end of the motor 20, causing the fan blades 21 to rotate when the motor 20 is started. Handles 22 are fixedly connected to the upper and lower sides of the support cylinder 1 for easy gripping. Auxiliary handles are fixedly connected to the front and rear sides of the guide tube 5 for assisting the user in holding the device.

[0036] Working principle: By gripping the handle 22, the support cylinder 1 is lifted, and the guide tube 5 can be raised using an auxiliary handle to prevent it from falling downwards. At this time, the motor 20 is started, driving multiple fan blades 21 to rotate, allowing the fan blades 21 to flow the gas inside the guide tube 5 into the support cylinder 1. Simultaneously, the electric push rod 14 is started, driving the concave block 15 to rotate, thereby driving the protective plate 16. Under the constraint of the two rotating plates 18, the protective plate 16 can rotate around the pin at the right end of the rotating plate 18, driving the sealing ring 17 to rotate. Utilizing the softness of the sealing ring 17, the sealing ring 17 can slide in close contact with the guide tube 5, thus keeping the guide tube... 5. When the left side is exposed, mosquitoes will be sucked into the inside of the guide tube 5 and stuck to the convex mosquito sticking board 4 under the action of negative pressure. At this time, the rotating protective plate 16 can be supported on the table or support point, thereby reducing hand fatigue. Conversely, the electric push rod 14 is activated, which can push the concave block 15 to rotate, and then drive the protective plate 16 to rotate again. At the same time, it rotates around the pin at the right end of the protective plate 16, so that the protective plate 16 can drive the sealing ring 17 to rotate to fit with the guide tube 5, thereby achieving a sealing effect and preventing dust from falling into the inside of the guide tube 5 and falling onto the convex mosquito sticking board 4 and the fan blade 21 when negative pressure is generated, thereby extending its service life.

[0037] When the convex mosquito sticky board 4 needs to be replaced and cleaned, the push plate 9 is held and the sliding ring 8 is pushed to slide, so that the sliding ring 8 no longer presses against the two limiting posts 12. At the same time, the sliding ring 8 will also compress the spring 7, so that the spring 7 can store elastic potential energy, and then give the sliding ring 8 a force in the opposite direction to reset it to press against the limiting posts 12. Then the guide tube 5 can be pulled to slide. At this time, the limiting posts 12 will be restricted by the connecting ring 2, so that the two limiting balls 11 will slide to the opposite side. At this time, the convex mosquito sticky board 4 can be removed for maintenance. Conversely, when installing the guide tube 5 and the connecting ring 2, the connecting ring 2 presses against the two limiting posts 12, so that the two limiting posts 12 slide to the opposite side. After sliding to fit, the pushing force on the push plate 9 is released. At this time, the spring 7 will reset and push the sliding ring 8 to reset, so that the two limiting posts 12 will slide to the side closer to the side and slide into the interior of the connecting ring 2. This can quickly complete the replacement and cleaning of the convex mosquito sticky board 4, thereby improving work efficiency.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
