Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and specifically relates to a telescopic spraying device. Background Technology

[0002] In recent years, with increasing demands from households for healthy and hygienic living environments, the demand for professional pest control services has grown significantly. Households typically rely on pest control companies for comprehensive pest control in their homes. However, existing commercial spraying equipment still faces numerous technical bottlenecks in actual operation, leading to low service efficiency, incomplete coverage, and even potential customer complaints. Modern residential structures are complex (e.g., built-in furniture, ceiling decorations, dense piping, narrow crevices), and traditional spraying equipment, with its fixed length and single nozzle angle, struggles to accurately cover hidden pest-infested areas (e.g., ceiling seams, the backs of cabinets, the bottoms of appliances). Operators often need to repeatedly move furniture or use ladders to work at heights, which is not only time-consuming and labor-intensive but may also cause damage to the customer's home.

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] As shown in Figures 1-3, this telescopic spraying device includes a telescopic rod 1, a water pump 2, and a nozzle 3. The telescopic rod 1 is provided with a clearance channel 4. An infusion channel 5 is provided between the water pump 2 and the nozzle 3. The infusion channel 5 is located within the clearance channel 4. The water pump 2 is used to pump the medicine to the nozzle 3. The nozzle 3 is provided with a steering device 6. The steering device 6 is located within the clearance channel 4 and is used to control the steering of the nozzle 3. The infusion channel 5 can be stored in a spiral manner within the clearance channel 4, or it can be a corrugated hose structure.

[0019] To elaborate further, the telescopic rod 1 includes a fixed tube 7 and a movable tube 8. The fixed tube 7 is provided with multiple limiting holes 9, and the movable tube 8 is provided with a spring buckle 10. The spring buckle 10 is used to insert into the limiting hole 9. The movable tube 8 can slide along the length direction of the fixed tube 7. By judging the required length in advance, the spring buckle 10 is moved to the corresponding limiting hole 9.

[0020] To elaborate further, the telescopic rod is equipped with an adjustment device, which includes an outer tube 11 and an inner tube 12. The outer tube 11 is used to connect the nozzle 3. The inner wall of the outer tube 11 is provided with a limiting groove 13, and the inner tube 12 is provided with a limiting block 14. The limiting block 14 can move along the length direction of the limiting groove 13. The outer tube 11 is fixedly connected to the moving tube 8. The tube 7 is provided with a C-shaped notch 15. An adjustment block 16 is provided on the outer tube 11. The adjustment block 16 passes through the C-shaped notch 15. This setting is used to enable the spraying area of ​​the liquid medicine to be driven by rotating the adjustment block 16 when spraying the liquid medicine, so that the liquid medicine is sprayed without dead corners. The rotation of the adjustment block 16 drives the outer tube 11 to rotate. The outer tube 11 and the inner tube 12 are limited by the limiting block 14, so that the outer tube 11 drives the inner tube 12 to rotate, thereby driving the nozzle 3 to rotate.

[0021] To elaborate further, multiple adjustment grooves 17 are provided on one side of the C-shaped notch 15. This arrangement is used to engage the limiting block 14 into the adjustment groove 17 for limiting and preventing the nozzle 3 from rotating left and right during use.
