[0025] As Figures 1-4As shown, two reinforcing plates 2 are fixedly connected to the outer surface of the outer shell 1. A support plate 3 is fixedly connected to the tops of the two reinforcing plates 2. A placement plate 15 is provided on the inner surface of the bottom of the outer shell 1. The support plate 3 is fixedly connected to the outer surface of the outer shell 1. A sealing door 20 is provided on the outer surface of the outer shell 1. A water tank 4 is fixedly connected to the top of the support plate 3. The support plate 3 can support the water tank 4 and provide a good working environment for the water tank 4.

[0026] As Figures 1-4 shown, the water replenishing mechanism includes a water replenishing pipe 5. The water replenishing pipe 5 is fixedly connected to the inner surface of the water tank 4. A fixing plate 6 is fixedly connected to the outer surface of the water replenishing pipe 5. The fixing plate 6 is fixedly connected to the inner wall of the water tank 4. The water replenishing pipe 5 can replenish water to the water tank 4 and provide a water source for subsequent spraying.

[0027] As Figures 1-4 shown, a Venturi tube 9 is fixedly connected to the outer surface of the water tank 4. The Venturi tube 9 can improve the stability of water flow and achieve a more uniform water flow distribution.

[0028] As Figures 1-4 shown, the outer surface of a conduit 10 is fixedly connected to the outer surface of the Venturi tube 9. The conduit 10 can introduce water into the connecting pipe 12 and provide sufficient water source for spraying.

[0029] As Figures 1-4 shown, the pulse jetting mechanism includes a pulse valve 16. The pulse valve 16 is fixedly connected to the outer surface of the outer shell 1. A connecting air pipe 17 is fixedly connected to the outer surface of the pulse valve 16. The connecting air pipe 17 is fixedly connected to the outer surface of the placement plate 15. The pulse valve 16 is provided on the outer surface of the outer shell 1. A jetting hole 18 is provided on the outer surface of the placement plate 15, which accelerates the evaporation of excess water on the surface of agricultural products, further ensures the preservation effect, and the excess water will be discharged from the drain pipe 19, which ensures the humidity inside the outer shell 1 to a certain extent and further ensures the preservation effect.

[0030] As Figures 1-4 shown, the drainage mechanism includes a drain pipe 19. The drain pipe 19 is fixedly connected to the inner surfaces of the outer shell 1 and the placement plate 15. The drain pipe 19 can discharge the excess water inside the outer shell 1 and ensure the balance of the humidity inside the outer shell 1 to a certain extent.

[0031] Working principle: This device is a spray-type agricultural product preservation device. When in use, open the sealing door 20, place the agricultural products to be preserved on the placement plate 15, and then close the sealing door 20. The reinforcing plates 2 and the support plate 3 can support the water tank 4. Then, connect the water replenishing pipe 5 on the fixing plate 6 to inject water into the water tank 4.

[0032] Using the principle of bell-jar siphon, water enters the water tank 4 from the flow splitter 7. As the water level in the water tank 4 rises, when the water level exceeds the highest point of the flow guide plate 8, the water begins to drain from the middle cavity formed by the two flow guide plates 8 and leave the water tank 4. When the water level in the water tank 4 is completely higher than the highest point of the flow guide plate 8, water seals will be formed in the relative cavity at the top of the flow guide plate 8 and the relative cavities between the flow splitter 7 and the flow guide plate 8. At this time, the water in the middle cavity of the two flow guide plates 8 will gradually fill the middle cavity of the flow guide plate 8, expelling the air in the cavity formed by the flow guide plate 8. As the air is expelled, the air hindering the water flow gradually decreases, and thus the flow rate of the water in the cavity formed by the flow guide plate 8 will gradually increase. When the water level in the water tank 4 is lower than the lowest point of the flow splitter 7, air will enter the two cavities formed by the flow splitter 7 and the flow guide plate 8, and then the water flow will gradually decrease. As the air increases, the water flow gradually decreases and finally stops, realizing intermittent water discharge.

[0033] When the water flow enters the inlet of the Venturi tube 9, the speed is relatively low and the pressure is relatively high. As the water flow enters the contraction section, the cross-sectional area of the pipeline becomes smaller, the water flow speed increases, and the pressure decreases, forming a negative pressure area. This negative pressure area can suck in additional water flow and enhance the flow effect. Subsequently, the water flow enters the expansion section, the cross-sectional area of the pipeline becomes larger, the water flow speed decreases, and the pressure rises. The water flow continues to flow towards the conduit 10, ensuring the stability of the water flow.

[0034] When the water flow enters the conduit 10, the water flow enters the connecting pipe 12. Since the nozzle 14 on the nozzle 13 is inclined, when the water is ejected, the water will give a reaction force to the nozzle 14, causing the nozzle 13 to rotate. Then, the connecting pipe 12 drives the rotating ring 11 to rotate on the inner surface of the conduit 10, realizing rotary spraying.

[0035] Then connect the connecting air pipe 17 to the air storage tank. The connecting air pipe 17 can introduce compressed air into the placement plate 15 and then eject it from the air jet holes 18. The compressed air can dry the moisture on the surface of the agricultural products, reduce the residues on the surface of the agricultural products, and at the same time blow out the excess water from the drain pipe 19 to maintain the humidity balance inside the housing 1.

[0036] The above is only the preferred embodiment of the present invention, and it does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
