DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1 - Figure 4 As shown, a spraying device with a quantitative function includes an outer cylinder 100, a nozzle 200 distributed in an array is provided on the front lower side of the outer cylinder 100, a quantitative mechanism distributed in an array is provided inside the outer cylinder 100, the quantitative mechanism includes an inner cylinder 301, a flip shaft 302 is fixedly connected to the front lower side of the inner cylinder 301, both ends of the flip shaft 302 are rotatably connected to longitudinal beams 303, both ends of the longitudinal beams 303 are fixedly connected to the outer cylinder 100, a locking plate 306 is provided on the rear side of the inner cylinder 301, a top plate 307 is fixedly connected to the front side of the locking plate 306, an adjusting component is provided inside the inner cylinder 301, a buoyancy block 308 is provided at the bottom end of the adjusting component, a sliding rod 305 is fixedly connected to the rear side of the locking plate 306, a column 304 is slidably connected to the rear end of the sliding rod 305, the bottom end of the column 304 is fixedly connected to the outer cylinder 100, a locking mechanism is provided on the top of the inner cylinder 301, and a reset mechanism is provided on one side of the inner cylinder 301.

[0025] The flip axis 302 is used to keep the inner cylinder 301 flippable, and the longitudinal beam 303 is used to keep the position of the flip axis 302. The multiple inner cylinders 301 are used to contain different types of liquid medicine. After the liquid medicine enters the inner cylinder 301, the buoyancy generated causes the buoyancy block 308 to rise, thereby causing the top plate 307 and the locking plate 306 to rise. The locking plate 306 then leaves the inner cylinder 301 and cooperates with the locking mechanism to lock the height of the locking plate 306. The inner cylinder 301 completes quantitative pouring, and the column 304 and the sliding rod 305 keep the locking plate 306 sliding up and down and limiting. The liquid medicine in the multiple inner cylinders 301 is mixed in the outer cylinder 100 and then sprayed.

[0026] The quantitative mechanism further includes a blocking rod 311 , which is disposed on the front side of the inner tube 301 , and both ends of the blocking rod 311 are fixedly connected to the longitudinal beam plate 303 .

[0027] The blocking rod 311 is used for limiting the position and preventing the inner cylinder 301 from turning forward.

[0028] The adjustment assembly includes a threaded rod 309 , the bottom end of the threaded rod 309 is rotatably connected to the buoyancy block 308 , the threaded rod 309 is threadedly connected to the top plate 307 , the top surface of the buoyancy block 308 is fixedly connected to a buoyancy block slide column 310 , and the buoyancy block slide column 310 is slidably connected to the top plate 307 .

[0029] When the threaded rod 309 rotates, it drives the buoyancy block 308 to rise and fall while achieving self-locking, thereby enabling the inner tube 301 to be tipped at different liquid level heights, achieving adjustable quantitative tipping. The float slide 310 is used to prevent the buoyancy block 308 from rotating excessively, so that the buoyancy block 308 can rise and fall driven by the threaded rod 309.

[0030] The locking mechanism includes a circular pit 402 , which is opened on the front side of the locking plate 306 , and a chamfer 401 is provided on the top of the front side of the locking plate 306 .

[0031] The chamfer 401 facilitates the passage of the ball head 403 . When the locking plate 306 rises, the round pit 402 rises, and the ball head 403 and the round pit 402 are engaged with each other.

[0032] The locking mechanism also includes a ball head 403, which cooperates with the round pit 402. The front end of the ball head 403 is fixedly connected to a transverse sliding column 404, and the transverse sliding column 404 is slidably connected to a transverse sliding sleeve 405. The top of the transverse sliding sleeve 405 is fixedly connected to a U-shaped column 408, and both ends of the U-shaped column 408 are fixedly connected to the longitudinal beam 303. The front end of the transverse sliding column 404 is fixedly connected to a release plate 407, and the bottom end of the release plate 407 extends to the front side of the inner tube 301. A spring 406 is provided on the outer side of the transverse sliding column 404, and both ends of the spring 406 are respectively fixedly connected to the transverse sliding sleeve 405 and the release plate 407.

[0033] The U-shaped column 408 is used to install the transverse sleeve 405, and the transverse sleeve 405 is used to slide and connect the transverse slide column 404. The transverse slide column 404 is used to install the ball head 403 and the spring 406. Under the action of the spring 406, the transverse slide column 404 is pulled to move backward while maintaining elasticity, so that the round pit 402 and the ball head 403 can be engaged. After the inner cylinder 301 finishes pouring and returns, it presses against the release plate 407, so that the transverse slide column 404 moves backward, so that the round pit 402 and the ball head 403 are released and engaged, and the locking plate 306 descends to break the nail inner cylinder 301.

[0034] The reset mechanism includes a gear 501 , which is fixedly connected to one end of the flip shaft 302 . The gear 501 is meshed with a rack 502 , and both ends of the rack 502 are slidably connected to the outer cylinder 100 .

[0035] Pushing the rack 502 causes the gear 501 to rotate, causing the flip shaft 302 to rotate, and finally driving the inner cylinder 301 to reset.

[0036] Working principle:

[0037] The threaded rod 309 is rotated according to the required proportion of the liquid medicine to adjust the height of the buoyancy block 308 so that buoyancy is generated on the buoyancy block 308 at different liquid medicine heights.

[0038] Then, different liquid medicines are poured into different inner cylinders 301. When the liquid medicines rise to the height of the bottom surface of the buoyancy block 308, more liquid medicines are added to generate buoyancy on the buoyancy block 308, thereby causing the top plate 307 and the locking plate 306 to rise. The locking plate 306 then leaves the inner cylinder 301 and cooperates with the locking mechanism to lock the height of the locking plate 306. The inner cylinder 301 completes quantitative pouring.

[0039] The top plate 307 and the locking plate 306 rise, so that the ball head 403 and the round pit 402 are engaged, so that the locking plate 306 will not fall temporarily. When the inner cylinder 301 is poured out, the reset mechanism resets the inner cylinder 301, and the inner cylinder 301 presses against the release plate 407, so that the release plate 407 pulls the transverse sliding column 404 and moves forward. The ball head 403 leaves the round pit 402, and the locking plate 306 falls under the action of gravity, extending the buoyancy block 308 into the inner cylinder 301, and quantitative addition can continue.

[0040] The rack 502 is manually controlled to move horizontally, driving the gear 501 and the turning shaft 302 to rotate, so that the inner cylinder 301 is turned over and reset.

[0041] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
