Description

Technical Field

[0001] This utility model relates to public health and vector-borne disease control equipment, and in particular a portable device that integrates three functions—negative pressure trapping, CO2 anesthesia, and liquid spraying—into a single handheld shell. It is suitable for the rapid capture, safe transfer, and localized chemical extermination of sanitary pests such as cockroaches, mosquitoes, and flies. Background Technology

[0002] Existing vector-borne disease control devices generally suffer from common defects such as fragmented functions and poor adaptability to different scenarios: First, electric suction devices can only provide negative pressure trapping and lack an immediate anesthesia unit, resulting in violent collisions of live insects in the dust collection chamber, low sample integrity, and a high risk of escape; Second, independent CO2 anesthesia systems rely on high-pressure cylinders and pressure reducing valves, making them bulky, heavy, and difficult to carry and deploy quickly on-site; Third, chemical spraying devices and insect traps are independent of each other, and switching operations are time-consuming, easily missing the optimal killing window; Fourth, existing handheld sprayers lack mechanical-electronic dual safety, and accidental spraying poses a potential phytotoxicity to operators and the surrounding environment; Fifth, using multiple devices simultaneously results in overall redundancy and cumulative energy consumption, making it difficult to meet the needs of urban sanitation emergencies requiring individual soldier portability and immediate use. Therefore, there is an urgent need for a lightweight device that integrates "safe trapping—rapid anesthesia—precise spraying" into a single handheld shell and has an anti-accidental-touch interlock to solve the problems of single function, low collaborative efficiency, and poor safety. Utility Model Content

[0003] This utility model discloses a handheld suction and spray integrated vector control device, which can complete multiple actions such as "insect suction - anesthesia - spraying" in the same handheld device. It has a compact structure, smooth operation, and is easy to carry. It can be widely used in scenarios such as home, catering, warehousing, port and post-disaster emergency.

[0004] (a) Technical problems to be solved 1. Solve the problems of insect damage and escape during the trapping process; 2.

When the child lock is not unlocked, the drug spraying start button is mechanically limited. The insect-absorbing function start button is used to control the motor, and the drug spraying start button is used to control the drug liquid control valve.

[0012] The workflow is as follows: When suctioning insects, press the insect suction function start button. The motor drives the fan impeller to generate negative pressure. Insects are drawn in through the suction nozzle by the airflow, blocked by the filter, and stored in the insect storage chamber. The filter prevents insects from entering the motor. After suctioning, turn the CO2 control valve. The small gas cylinder releases CO2 into the insect storage chamber to anesthetize the insects. Remove the insect storage chamber and pour out the anesthetized insects. When spraying is needed, first unlock the child lock, then press the drug spray start button. The drug control valve opens, and the drug is atomized and sprayed out from the drug spray outlet for targeted elimination.
