AI Technical Summary
The existing sampler for pesticide quality testing is not conducive to rapid disinfection during the disinfection process, and the overall disinfection effect is poor, increasing the risk of hazards for staff.
A sampler for pesticide quality detection is designed, using socket rings, limit columns, moving blocks, rack plates and telescopic columns. Through the movement of rack plates, the moving blocks are driven to promote sampling and suction on the socket ring. The head falls off, which realizes automatic disengagement of the suction head, which facilitates rapid disinfection and prevents the suction head from falling off unexpectedly through the tight engagement of the sealing ring and the spring.
The rapid shedding and disinfection of the sampling suction head is achieved, reducing the risk of hazards caused by pesticide contamination by staff, and improving disinfection efficiency and safety.
