DETAILED DESCRIPTION

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0021] Reference Figure 1-6 The figure shows a pneumatic plastic watering can, comprising a can body 1, a can lid 2 being threadedly mounted on the surface of the can body 1, a ventilation pipe 3 being fixedly mounted on the bottom surface of the cover plate corresponding to the can body 1, a sealing assembly 4 being fixedly mounted on the lower end of the ventilation pipe 3, the sealing assembly 4 allowing external air to enter the can body 1 and seal the ventilation pipe 3 in time to prevent liquid from leaving the watering can through the ventilation pipe 3, a second baffle 15 being arranged inside the sealing assembly 4, a connecting rod 6 being arranged inside the ventilation pipe 3, a rack 5 being arranged inside the ventilation pipe 3 corresponding to the connecting rod 6, a first gear 7 being arranged inside the ventilation pipe 3 corresponding to the rack 5, a connecting shaft 8 being fixedly mounted on one side of the first gear 7, the connecting shaft 8 passing through the ventilation pipe 3, a second gear 9 being fixedly mounted on the end of the connecting shaft 8 away from the first gear 7, a stirring assembly 10 being arranged inside the can body 1 corresponding to the second gear 9, the rack 5 driving the first gear 7 to rotate during movement, the first gear 7 rotating the second gear 9 through the connecting shaft 8, and the second gear 9 driving the stirring assembly 10 to stir the liquid in the can body 1.

[0022] like Figure 4As shown, the sealing assembly 4 includes a connecting pipe 11 and a limiting plate 21. A first baffle 12 is fixedly installed on the bottom of the inner wall of the connecting pipe 11. A through groove 13 is opened at the center of the first baffle 12. A plurality of limiting rods 14 are fixedly installed on the inner wall of the connecting pipe 11 corresponding to the first baffle 12. The plurality of limiting rods 14 are distributed around the center line of the connecting pipe 11. A second baffle 15 is provided above the limiting plate 21. A ventilation hole 16 is opened at the center of the second baffle 15. A first sealing plate 17 is provided inside the ventilation hole 16. A guide rod 1 is fixedly installed on the lower surface of the first sealing plate 17. 8. A spring 19 is sleeved on the outer surface of the guide rod 18, and the two ends of the spring 19 are fixedly connected to the upper surface of the first baffle 12 and the bottom surface of the first sealing plate 17 respectively. When the external air is squeezed, the high-pressure gas in the ventilation pipe 3 pushes the first sealing plate 17 to move, and then the high-pressure gas enters the kettle body 1 through the ventilation holes 16 and the through grooves 13 in sequence. When the air pressure in the ventilation pipe 3 is balanced with the air pressure in the kettle body 1, the spring 19 pushes the first sealing plate 17 into the ventilation holes 16, thereby separating the ventilation pipe 3 from the kettle body 1, thereby preventing the liquid in the kettle body 1 from leaving the water sprayer through the ventilation pipe 3.

[0023] like Figure 5 As shown, the stirring assembly 10 includes a fixing frame 20, which is fixedly connected to the outer surface of the ventilation pipe 3, and the outer surface of the fixing frame 20 is sleeved with a special-shaped gear 22. The second gear 9 is meshed with the special-shaped gear 22. The outer surface of the connecting rod 6 is fixedly installed with two fixing plates 26 corresponding to the ventilation pipe 3. The fixing plate 26 is fixedly connected to the inner wall of the kettle body 1. A rotating ring 23 is provided inside the limiting plate 21. Several support rods 24 are provided between the rotating ring 23 and the special-shaped gear 22. Several support rods 24 are distributed around the center line of the ventilation pipe 3. The outer surfaces of several support rods 24 are fixedly installed with stirring plates 25. The second gear 9 rotates to rotate the special-shaped gear 22, and the special-shaped gear 22 drives the stirring plate on the support rod 24 to stir the liquid, so that the substances in the liquid are fully mixed.

[0024] like Figure 3-6 As shown, the rack 5 is fixedly connected to the fixed plate 26 at the lower end of the connecting rod 6, and a second sealing plate 27 corresponding to the ventilation pipe 3 is provided between the two fixed plates 26. The user repeatedly pushes and pulls the connecting rod 6, and the connecting rod 6 drives the second sealing plate 27 to squeeze the gas in the ventilation pipe 3, thereby increasing the air pressure in the ventilation pipe 3. A water pipe 28 is provided inside the kettle body 1 corresponding to the ventilation pipe 3. The end of the water pipe 28 away from the kettle body 1 is connected to the nozzle 29. A valve 30 is movably installed on the outer surface of the nozzle 29 corresponding to the water pipe 28. The valve 30 is fixedly connected to the kettle cover 2. After the valve 30 is opened, the high-pressure gas in the kettle body 1 pushes the liquid in the kettle body 1 to spray water to the target area through the water pipe 28 and the nozzle 29 in turn.

[0025] like Figure 6As shown, a handle 31 is fixedly installed on the side of the pot cover 2 away from the nozzle 29. The handle 31 provides a convenient and comfortable gripping point for the user, allowing the user to pick up, put down or operate the watering can more easily. Through the handle 31, the user can control the watering can more stably, reducing the risk of inaccurate spraying or the watering can falling due to hand slippage or instability, thereby ensuring the safety and accuracy of the operation.

[0026] like Figure 6 As shown, a squeezing plate 32 is provided above the handle 31, and the squeezing plate 32 is connected to the valve 30 through the support rod 24. The support rod 24 is hinged to the pot lid 2. After the nozzle is aimed at the target area, the user presses the squeezing plate 32, and then the support rod 24 drives the valve 30 to open, thereby completing the spraying of the target area.

[0027] Working principle: the user pours the medicine liquid and clean water into the kettle body 1, rotates the kettle lid 2 to seal the kettle body 1, and repeatedly pushes and pulls the connecting rod 6. During each push and pull process, the connecting rod 6 drives the second sealing plate 27 to compress the gas in the ventilation pipe 3, and the high-pressure gas in the ventilation pipe 3 pushes the first sealing plate 17 to move, and then the high-pressure gas enters the kettle body 1 through the ventilation hole 16 and the through groove 13 in turn. When the air pressure in the ventilation pipe 3 is balanced with the air pressure in the kettle body 1, the spring 19 pushes the first sealing plate 17 into the ventilation hole 16, thereby separating the ventilation pipe 3 from the kettle body 1; during each push and pull When the connecting rod 6 is connected, the fixed plate 26 on the connecting rod 6 drives the rack 5 to move, and in the process of the movement of the rack 5, it drives the first gear 7 to rotate. The first gear 7 rotates the second gear 9 through the connecting shaft 8, and the second gear 9 drives the special-shaped gear 22 in the stirring assembly 10 to rotate. The special-shaped gear 22 drives the stirring plate on the support rod 24 to stir the liquid, so that the medicine and the liquid are fully mixed. The user presses the squeezing plate 32 to make the support rod 24 drive the valve 30 to open, and the high-pressure gas in the kettle body 1 pushes the liquid in the kettle body 1 through the water pipe 28 and the nozzle 29 in turn to spray water on the target area.
