Description

Technical Field

[0001] The utility model relates to the field of sprayers, in particular to a medicine adding structure of a backpack sprayer. Background Art

[0002] Knapsack sprayers are mainly used to evenly spray liquid medicine or other liquids in the form of mist onto target objects. They are widely used in the fields of pest control, disinfection and sterilization, plant nutrition supply, and environmental sanitation. In traditional backpack sprayer designs, the dosing process is often a relatively tedious and time-consuming step. Users are usually required to remove the sprayer from their backs first in order to open the lid of the liquid medicine barrel to add medicine, and then put the sprayer back on their backs after dosing is completed. This process requires users to spend a lot of time and physical strength to complete, which is not only inefficient, but also increases the inconvenience and potential safety risks during operation.

[0003] For example, the utility model patent (application number: 202322419545.3) discloses a "backpack electric air-assisted sprayer for agricultural pesticide application". The specification discloses that the sprayer comprises a spray box, a grinding seat is provided inside the treatment cylinder, a rotating disk is movably installed inside the side groove through a rotating shaft, a rotating swing arm is fixedly connected to the bottom side of the rotating disk, a spray pipe is fixedly provided inside the rotating swing arm, and a spray nozzle is fixedly connected to one end of the spray nozzle. The grinding seat driven by a driving motor is provided inside the treatment cylinder of the utility model, which can crush and grind the tablets added to the treatment cylinder, and then liquid is introduced to mix the tablet powder and the spray liquid evenly. After the treatment is completed, the mixed liquid is directly introduced into the spray box, realizing rapid dosing without waiting for dissolution. A rotating swing arm is also provided on the outside of the bottom of the spray box, which is rotated by the rotating disk. When the rotating swing arm rotates, it can drive the spray pipe and the spray nozzle to rotate, thereby realizing automatic steering spray operation, which is more convenient when applying pesticides to farmland. The above patents can prove the defects of the existing technology.

[0004] Therefore, we have made improvements to this and proposed a dosing structure for a backpack sprayer. Summary of the Invention

[0041] When it is necessary to connect the connecting assembly 5 with the fixing assembly 9 for adding medicine, the user reaches behind and takes out the connecting assembly 5 from the clamping assembly 4, turns the connecting assembly 5 so that the second limiting ring 503 is at the bottom, and places it inside the limiting groove for restriction. Then, the second mounting tube 903 is rotated to make the first sealing gasket 504 at the bottom of the connecting tube 501 contact with the second mounting tube 602, thereby tightly connecting them. Then, the control switch 10 starts the water pump to transfer the liquid in the storage barrel 2 through the first mounting tube 601, the second mounting tube 602 and the connecting tube 201 to the interior of the storage bin 1 for replenishment.

[0042] When the guide arc plate 701 is not needed or the transmission length of the liquid medicine needs to be shortened, rotate the No. 1 mounting cylinder 801 to disengage it from the No. 1 mounting tube 601 through a thread, then rotate the No. 2 mounting cylinder 903 to disengage the fixing assembly 9 from the No. 2 mounting tube 602, then connect the No. 2 mounting cylinder 903 to the No. 1 mounting tube 601 through a thread, and the No. 2 mounting tube 602 and the guide arc plate 701 can be removed.
