[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] This utility model provides a technical solution: such as Figure 1 - Figure 5 As shown in this embodiment, an ultra-low volume sprayer with adjustable function includes: a medicine storage tank 1, a pump 11 installed at the outlet of the medicine storage tank 1, an adjusting cylinder 2 installed on one side of the pump 11, a cavity opened inside the adjusting cylinder 2, a guide strip 23 fixedly connected to one side of the inner wall of the cavity, an actuating ring 21 rotatably connected to the inner wall of the guide strip 23, a squeezing groove 24 penetrating through the middle of one side of the actuating ring 21, the squeezing groove 24 being elliptical inside the actuating ring 21, and a hose 22 fixedly connected to the output end of the pump 11, the hose 22 passing through the adjusting cylinder 2, and the hose 22 being located inside the squeezing groove 24.

[0020] Through the structural design of the actuating ring 21, hose 22, and extrusion groove 24, the operator actuates the actuating ring 21, which rotates within the guide bar 23. The inner wall of the extrusion groove 24 extrudes the hose 22, deforming it and reducing its flow size, thus decreasing the amount of pesticide sprayed. This structural design allows for adjustment of the actuating angle of the actuating ring 21 to control the amount of pesticide sprayed, enabling the equipment to spray pesticides on different livestock and poultry houses and improving its versatility.

[0021] It should be noted that when moving the toggle ring 21, the operator should move the toggle ring 21 upwards.

[0022] like Figure 2 , Figure 3 and Figure 5 As shown, a limiting ring 4 is fixedly connected to the other side of the inner wall of the adjusting cylinder 2. The inner wall of the limiting ring 4 is provided with an abutment groove 43. A rotating ring 41 is fixedly connected to one side of the actuating ring 21. An abutment rod 42 is rotatably connected to one side of the rotating ring 41. One end of the abutment rod 42 abuts in the abutment groove 43. A spring 44 is fixedly connected between the abutment rod 42 and the rotating ring 41. Multiple abutment grooves 43 are provided in the limiting ring 4. The abutment rod 42 is engaged in any of the abutment grooves 43.

[0023] Through the structural design of the limiting ring 4, rotating ring 41, abutting rod 42, abutting groove 43, and spring 44, the actuating ring 21 can only rotate in one direction, preventing the actuating ring 21 from rotating in the opposite direction, which would cause the flow size of the hose 22 to increase. At the same time, multiple abutting grooves 43 are opened on the limiting ring 4, so that the actuating ring 21 can be set to multiple positions. When the operator moves the actuating ring 21, the rotating ring 41 and the abutting rod 42 rotate together. One end of the abutting rod 42 moves into another abutting groove 43 on the limiting ring 4. The reaction force of the spring 44 pushes the abutting rod 42, and one end of the abutting rod 42 hits the abutting groove 43 and makes a sound, reminding the user that the position has been adjusted, thus improving the convenience of adjusting the spray volume of the equipment.

[0024] like Figure 3 and Figure 4 As shown, a rubber strip 26 is fixedly connected to the inner wall of the extrusion groove 24; multiple rubber strips 26 are provided on the inner wall of the extrusion groove 24. The rubber strips 26 are used to protect the hose 22 and facilitate the extrusion of the hose 22.

[0025] like Figure 1 and Figure 2 As shown, one end of the hose 22 is fixedly connected to the corrugated pipe 3, and one end of the corrugated pipe 3 is equipped with a nozzle 14. The upper end of the nozzle 14 is fixedly connected to a handle 31. The corrugated pipe 3 can extend and retract the nozzle 14, and adjust its direction, increasing the flexibility of spraying.

[0026] like Figure 1 As shown, a handle 12 is fixedly connected to the upper end of the medicine storage tank 1, and a sealing cap 13 is threadedly connected to the outer surface of the water inlet pipe of the medicine storage tank 1; the handle 12 is used to facilitate the staff to pick up the equipment; the sealing cap 13 is used to seal the medicine inlet pipe of the medicine storage tank 1 to prevent dust and impurities from entering.

[0027] like Figure 3 and Figure 4 As shown, the outer surface of the actuating ring 21 is provided with an anti-slip groove 25; the anti-slip groove 25 makes it convenient for the staff to move the actuating ring 21 and prevents the surface of the actuating ring 21 from being too smooth, which would make it difficult to rotate the actuating ring 21.

[0028] This utility model provides an ultra-low volume sprayer with adjustable function, and its working principle is as follows: When disinfecting livestock and poultry farms, the pump 11 is turned on, and the medicine in the storage tank 1 is delivered to the spray head 14 through the hose 22 and the corrugated pipe 3. The spray head 14 disinfects the livestock and poultry farm. When spraying medicine on smaller livestock and poultry sheds, the operator moves the actuating ring 21. The actuating ring 21 rotates in the guide bar 23, and the inner wall of the squeezing groove 24 squeezes the hose 22, deforming the hose 22 and reducing the flow size of the hose 22. At the same time, when the actuating ring 21 is rotated, the rotating ring 41 and the abutment rod 42 rotate together. One end of the abutment rod 42 moves into another abutment groove 43 on the limiting ring 4. The reaction force of the spring 44 pushes the abutment rod 42, and one end of the abutment rod 42 hits the abutment groove 43 and makes a sound, reminding the user that the gear has been adjusted, thereby adjusting the spray volume of the equipment. The above operation is repeated to disinfect the livestock and poultry farm.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
