Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1, such as Figures 1-3 The present invention provides the following technical solution to address the problem of inconvenient cleaning of the spray head of the dosing device: a rotating mechanism is disclosed.

[0031] The system includes a housing 1, a cartridge 2 connected to the top of the housing 1, a spray gun 3 connected to the front of the housing 1, a nozzle 4 connected to the output end of the spray gun 3, an external block 401 connected to the top of the nozzle 4, a first rotating groove 402 formed at the bottom of the external block 401, a motor installed inside the external block 401 near the first rotating groove 402, a gear 403 fixed to the output end of the motor, the gear 403 rotating inside the first rotating groove 402, a switch 405 connected to the upper surface of the external block 401, and a rotating mechanism for cleaning the spray head installed inside the external block 401. The nozzle 4 is located near the end of the spray gun 3. An external tube 416 is connected, and a disassembly and assembly mechanism for disassembling the spray head is provided at the end of the external tube 416. The rotating mechanism includes a battery pack 404, which is located inside the external block 401 near the switch 405. An internal gear ring 406 is connected to the surface of the spray head 4, and the internal gear ring 406 is meshed with the bottom of the gear 403. A sealing shaft 407 is installed between the spray head 4 and the external tube 416. A rotating block 408 is fixed to the surface of the spray head 4 near the sealing shaft 407. The rotating block 408 rotates inside the fixed cavity 409, and the fixed cavity 409 is fixed to the surface of the internal gear ring 406.

[0032] When the dosing device is in use, the medicine inside the cartridge 2 flows into the tank 1 for mixing. The mixed medicine is then transported to the spray gun 3 and sprayed out through the nozzle 4. When the nozzle needs to be cleaned for a short time, pressing the switch 405 can start the motor. The motor output can rotate using the electric drive provided by the battery pack 404. When the motor output rotates, it drives the gear 403 to rotate. When the gear 403 rotates, it meshes and drives the internal gear ring 406 to rotate. When the internal gear ring 406 rotates, it drives the nozzle 4 to rotate. The nozzle 4 can rotate with the outer cylinder 416 through the sealing shaft 407. When the nozzle 4 rotates, it drives the rotating block 408 to rotate. The rotating block 408 can rotate inside the fixed cavity 409, which improves the stability of the rotation. When the nozzle 4 rotates, it can be inserted into clean water for cleaning. The high-speed rotation of the nozzle 4 can impact the water, thereby cleaning the nozzle.

[0033] Example 2, as follows Figure 3 and Figure 4 The present invention provides the following technical solution to improve the maintenance efficiency of spray heads and reduce replacement costs after damage: A locking mechanism is disclosed.

[0034] The outer block 401 also has a locking mechanism for assembling and disassembling the rotating mechanism. The locking mechanism includes a telescopic groove 410, which extends through the inner side of the outer block 401. A telescopic block 411 slides inside the telescopic groove 410. A spring connects the telescopic block 411 and the telescopic groove 410. A pull rod 412 is fixed to the side of the telescopic block 411 near the spring. The pull rod 412 slides through the telescopic groove 410. A guide block 413 is fixed to the inner side of the outer block 401 away from the telescopic groove 410. The guide block 413 is slidably connected to the guide groove 414. The guide groove 414 is located at the top of the fixed cavity 409. A locking groove 415 is provided on the side of the fixed cavity 409 away from the guide groove 414. The slot 415 and the telescopic block 411 are engaged. After the spray head of the dosing device is cleaned, pulling the lever 412 can move the telescopic block 411. When the telescopic block 411 moves, it can slide through the telescopic groove 410 and the slot 415. When the telescopic block 411 slides out of the slot 415, it pushes the outer block 401 upward. When the outer block 401 is pushed upward, it can move the guide block 413. When the guide block 413 moves, it can slide through the guide groove 414. When the guide block 413 slides out of the guide groove 414, the outer block 401 can be disassembled. After the outer block 401 is disassembled, it is convenient to charge the battery pack 404 and to maintain the spray head 4, which improves the ease of use of the rotating mechanism.

[0035] Example 3, as follows Figure 2 , Figure 5 , Figure 6 and Figure 7 The present invention provides the following technical solution to address the problem of insufficient cleaning effect of the spray head in the dosing device: A disassembly and assembly mechanism is disclosed.

[0036] The disassembly and assembly mechanism includes a connecting block 417, which is fixed to the end of the spray gun 3 near the nozzle 4.

Three sets of sliding grooves 419 are provided on the side of the second rotating groove 418 away from the spray gun 3. A threaded rod 420 rotates through the sliding groove 419 via bearings. A slider 421 is threadedly connected to the surface of the threaded rod 420 and slides inside the sliding groove 419. The slider 421 is engaged with a positioning groove 423, which is located on the side of a positioning block 422. Three positioning blocks 422 are fixed to the surface of the outer casing 416. When the dosing device needs to better clean the spray head, the threaded rod 420 can be rotated via the bearings. The rotation of the threaded rod 420 drives the slider 421. When the slider 421 slides thread-slid, it can slide through the slide groove 419 and the positioning groove 423. When the slider 421 slides into the slide groove 419, the outer tube 416 rotates. When the outer tube 416 rotates, it can rotate through the second rotating groove 418. When the outer tube 416 rotates, it can drive the positioning block 422 to rotate. After the positioning block 422 rotates to the designated position, it pulls the outer tube 416 to the side. The outer tube 416 can then drive the positioning block 422 to slide out of the second rotating groove 418, realizing the disassembly of the outer tube 416. After the outer tube 416 is disassembled, it can drive the nozzle 4 to separate from the spray gun 3, which is convenient for cleaning the nozzle 4 thoroughly. It can also replace the nozzle 4 with a new one after it is damaged, further improving the cleaning effect of the spray head.
