Technical Field

[0001] This utility model relates to the field of fruit and vegetable sprayers, and in particular to a fruit and vegetable sprayer with a baffle to prevent mis-spraying. Background Technology

[0002] Fruit and vegetable sprayers are commonly used agricultural tools in fruit and vegetable cultivation. Their core purpose is to atomize pesticides or protective solutions and spray them evenly onto the leaves, branches, and fruit surfaces of fruit trees and vegetables, thereby preventing pests and diseases, reducing crop damage, and ensuring normal growth and yield. They are suitable for various planting scenarios such as home gardening, vegetable gardens, and orchards. They are easy to operate, even for non-professionals. Using diluted pesticides can reduce the labor intensity of manual spraying, improve pesticide utilization, reduce waste, and minimize the risk of direct contact with operators. They are practical tools for ensuring healthy fruit and vegetable growth and improving planting efficiency.

[0003] However, current fruit and vegetable sprayers have the following defects: First, they lack a structure to shield the plants, resulting in no baffle to shield non-sprayed parts of the plants to avoid accidental spraying of pesticides during spraying. Second, they lack a structure to protect the nozzles, making it easy for external dust to enter the nozzle orifices and cause blockages when the nozzles are not in use. In response to this technical problem, this application proposes a fruit and vegetable sprayer with a mis-spraying baffle. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fruit and vegetable sprayer with an anti-mis-spray baffle. This baffle is designed to shield the plant from spraying other areas, preventing pesticide from splashing onto other parts of the plant during spraying, and to protect the nozzle from external contaminants entering the nozzle orifice and causing blockage when the nozzle is not in use. The baffle can also function when not in use, achieving a dual-purpose effect.

(See reference...) Figure 5 and Figure 6 A round rod 18 is fitted inside the bolt 7. A pull rod 17 is fixedly connected to the top of the round rod 18. Two square plates 19 are fixedly connected to the bottom of the outer wall of the round rod 18. A circular cavity is opened on the bottom side inside the bolt 7. The bottom end of the round rod 18 is located inside the cavity. A square groove matching the square plate 19 is opened inside the bolt 7. The square groove is connected to the cavity and is located above the cavity. By slowly pulling and rotating the pull rod 17, the round rod 18 is rotated and slid inside the cavity, allowing the square plate 19 to rotate, thereby aligning with the square groove and finally inserting into the square groove. Then, the pull rod 17 is rotated so that the square plate 19 is rotated through the round rod 18. Under the restriction of the square groove, the bolt 7 is rotated. This allows the operator to disassemble and assemble the bolt 7 by hand without tools such as wrenches, making it convenient for the operator to disassemble and assemble the nozzle 2 without tools. The top of bolt 7 has a groove, and pull rod 17 is located inside the groove. A cover plate 15 is rotatably connected to the top side of the groove. Two protrusions 16 are fixedly connected to one side of the cover plate 15, and a pull ring 20 is fixedly connected to the other side of the cover plate 15. Two slots matching the protrusions 16 are formed on the top side of the groove. The protrusions 16 engage with the slots, thereby improving the stability of the cover plate 15 in the groove. By pulling the pull ring 20, the cover plate 15 is rotated, opening the groove, allowing operation of the pull rod 17, which is then protected by the cover plate 15.

[0019] Reference Figures 2-4The handle 1 has a metal rod 4 on its outside. The nozzle 2 has a baffle 3 on its left side. Two rods 14 are fixedly connected to the right side of the baffle 3. A threaded groove 9 is fixedly connected to the front side of the baffle 3. A threaded post 8 is fixedly connected to one end of the metal rod 4. The threaded post 8 is threaded into the inside of the threaded groove 9. The metal rod 4 and the baffle 3 are connected by threading the threaded post 8 into the inside of the threaded groove 9. When the operator is spraying pesticide, he can hold the metal rod 4 so that the baffle 3 can block other parts of the plant except the spraying area, preventing the pesticide from being sprayed onto other parts of the plant. A fixing block 10 is fixedly connected to the top side of the outer wall of the grip 1. A rotating ring 11 is rotatably connected to the top sides of both the fixing block 10 and the baffle 3. The top sides of both the fixing block 10 and the baffle 3 are connected to the rotating ring 11 via a torsion spring. A positioning ring 12 is fixedly connected to the bottom side of the rotating ring 11. Two positioning grooves matching the positioning ring 12 are formed on the outer wall of the metal rod 4. The positioning ring 12 engages inside the positioning grooves. A latching block 13 is fixedly connected to the bottom side of the rotating ring 11. A latching groove is formed on the top sides of both the fixing block 10 and the baffle 3. The latching block 13 engages inside the latching groove. The baffle 3 is attached to the nozzle 2, and the insert rod 14 is inserted into the nozzle hole of the nozzle 2. Then, the metal rod 4 is placed on the top side of the baffle 3 and the fixing block 10, and the positioning groove is aligned with the positioning ring 12. Then, the rotating ring 11 is rotated to make the positioning ring 12 engage in the snap-fit ​​groove, and the snap-fit ​​block 13 engages in the snap-fit ​​groove, thereby fixing the baffle 3 to the left side of the nozzle 2, thus protecting the nozzle 2 and preventing external dirt from entering the nozzle hole of the nozzle 2 and causing blockage when the nozzle 2 is not in use. This allows the baffle 3 to play a role even when it is not in use, achieving the effect of one plate serving two purposes.

[0020] Working principle: First, rotate the rotating ring 11 to disengage the positioning ring 12 and the snap-fit ​​block 13 from the positioning groove and snap-fit ​​groove respectively. Then, remove the metal rod 4 from the top side of the baffle 3 and the fixing block 10. After that, thread the threaded post 8 into the inside of the threaded groove 9 to connect the metal rod 4 and the baffle 3. When spraying, you can hold the metal rod 4 to block the baffle 3 from other parts of the plant except the spraying area to prevent the pesticide from spraying onto other parts of the plant. When it is necessary to disassemble or assemble bolt 7, pull the pull ring 20 to rotate the cover plate 15, thereby opening the groove. Then, slowly pull and rotate the pull rod 17 to make it rotate and slide with the round rod 18 inside the cavity, so that the square plate 19 can rotate, thereby aligning with the square groove and finally inserting into the square groove. After that, rotate the pull rod 17 to make it rotate with the square plate 19 through the round rod 18. Under the restriction of the square groove, it makes it rotate with bolt 7, thereby disassembling or assembling bolt 7, thereby disassembling or assembling nozzle 2. This allows the operator to disassemble or assemble nozzle 2 without tools.
