Description

Technical Field

[0001] This invention relates to the field of lychee preservation technology, specifically a watering device for lychee preservation. Background Technology

[0002] Lychee is an evergreen tree belonging to the Sapindaceae family and the Litchi genus, reaching a height of about 10 meters. The fruit peel has scaly protrusions, and is bright red, purplish-red, and becomes bright red when ripe; the seeds are completely covered by a fleshy aril. It flowers in spring and fruits in summer. When fresh, the pulp is translucent and jelly-like, with a fragrant and delicious taste, but it does not store well.

[0003] Patent document CN214854036U discloses a lychee sales preservation water spraying device, which includes a box body, a shell connected to the bottom of the box body, a filter element bolted inside the shell, a water storage tank connected to the bottom of the shell, a water pump connected to one side of the water storage tank, a pipe connected to the top of the water storage tank, and a spray pipe connected to the other end of the pipe.

[0004] In use, the above design involves placing lychees inside the box, then activating a water pump to extract the preservative water from the storage tank. This water is then piped into the spray nozzles, where it sprays water to keep the lychees fresh. The sprayed preservative water flows through a filter plate into the shell, then through a filter cartridge before flowing back into the storage tank, effectively circulating the water and saving a significant amount of preservative water. However, in actual use, the nozzles are installed at the bottom edge of the shade. Only half of the water sprays onto the lychee surface, while the other half is sprayed onto the outside of the box, resulting in waste and water stains that affect sales.

[0005] Therefore, a watering device for lychee preservation is proposed to address the above problems. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies and solve the problems of water waste and sales impact caused by excessively large spray range of nozzles, this invention proposes a watering device for lychee preservation.

[0007] A watering device for preserving lychees includes a display stand, wherein a placement plate is slidably installed in the inner cavity of the display stand. It also includes a spraying mechanism for spraying the lychees; The spraying mechanism includes a support plate, which is fixedly installed on the top of the platform. A third groove is provided on the top of the support plate, and a slider is slidably installed in the inner cavity of the third groove. A first water pipe is rotatably installed on one side of the slider, and several nozzles are fixedly installed at the bottom of the first water pipe.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1 to 8 As shown, a watering device for preserving lychees includes a display stand 1, with a placement plate 14 slidably installed inside the display stand 1; it also includes a spraying mechanism for spraying the lychees; the spraying mechanism includes a support plate 2, which is fixedly installed on the top of the display stand 1. A third groove 21 is provided on the top of the support plate 2, and a slider 24 is slidably installed inside the third groove 21. A first water pipe 242 is rotatably installed on one side of the slider 24, and several nozzles 243 are fixedly installed at the bottom of the first water pipe 242. A first gear 2421 and a second gear 2422 are rotatably installed on the top of the slider 24, and the first gear 2421 and the second gear 2422 mesh with each other. The first gear 2421 is fixedly connected to the first water pipe 242. A rack 2423 is fixedly installed on the top of the support plate 2, and the rack 2423 meshes with the second gear 2422. A second water pipe 244 is fixedly connected to the top of the slider 24.

[0025] Existing lychee display racks are prone to getting water on the surrounding area when sprayed with water, which affects sales and the preservation of the lychees.

[0026] In use, the lychees are first placed on the placement plate 14. When it is necessary to spray water to keep the lychees fresh, the slider 24 slides in the inner cavity of the third groove 21. At this time, the second gear 2422 is rotated by the rack 2423. The second gear 2422 further drives the first gear 2421 to rotate. The first gear 2421 drives the first water pipe 242 to rotate to the top of the placement plate 14. Before starting, the first water pipe 242 is close to the side of the support plate 2. When in use, the first water pipe 242 slides on the top of the placement plate 14 with the slider 24. Water is delivered to the inner cavity of the first water pipe 242 through the second water pipe 244 and finally sprayed out through several nozzles 243. This can achieve the work of spraying water to keep the lychees fresh, and can also avoid water waste and prevent water from spraying around the display stand 1, which may cause customers to slip when they approach the display stand 1.

[0027] Furthermore, such as Figure 5 As shown, a threaded rod 22 is rotatably installed in the inner cavity of the third groove 21. A motor 23 is fixedly connected to one end of the threaded rod 22. The motor 23 is fixedly connected to the support plate 2. The slider 24 is threadedly connected to the threaded rod 22. A baffle 241 is fixedly installed on one side of the slider 24, and a first rotating block 2424 is rotatably installed on the top of the first water pipe 242. A spring 2426 is fixedly connected to one side of the first rotating block 2424, and a second rotating block 2425 is fixedly connected to one end of the spring 2426. The second rotating block 2425 is rotatably connected to the slider 24.

[0028] In use, the output shaft of motor 23 drives the threaded rod 22 to rotate. This, combined with the limiting position of the slider 24 by the third groove 21, allows the slider 24 to slide stably within the third groove 21. Simultaneously, when the first gear 2421 drives the first water pipe 242 to rotate to a position perpendicular to the support plate 2, the spring 2426 is compressed, thus possessing elastic potential energy. One end of the spring 2426 supports the first rotating block 2424, thereby stabilizing the first water pipe 242. Therefore, the spring 2426 supports the first water pipe 242. To prevent the spring 2426 from excessively rotating the first water pipe 242 during sliding, [the following is a continuation of the previous sentence, which is not directly related to the previous paragraph]. The baffle 241 blocks the first water pipe 242. The meshing distance between the second gear 2422 and the rack 2423 is just enough to make the first water pipe 242 rotate 90 degrees. When in use, the first water pipe 242 is in a state of maintaining a 90-degree angle with the support plate 2 and slides on one side of the support plate 2. When the first water pipe 242 is retracted, the second gear 2422 meshes with the rack 2423 again. After meshing, the second gear 2422 drives the first gear 2421 to rotate. The first gear 2421 drives the first water pipe 242 to rotate, so that the first water pipe 242 is close to the support plate 2 and keeps parallel to the support plate 2. When the first water pipe 242 slides on the top of the display stand 1, water is sprayed to keep the lychees fresh.

[0029] Furthermore, such as Figure 2 and Figure 7 As shown, the top of the display stand 1 is provided with a plurality of first grooves 11, and the inner cavity of the first grooves 11 is fixedly installed with heat insulation cotton 12; The top of the table 1 is provided with several second grooves 13, and a connecting plate is slidably installed in the inner cavity of the second groove 13. The connecting plate is fixedly connected to the placement plate 14, and the top of the placement plate 14 is provided with several through holes. A fourth groove 6 is provided on one side of the display stand 1, and a rotating plate 61 is rotatably installed in the inner cavity of the fourth groove 6.

[0030] In use, to keep the lychee at a low temperature when it is placed on top of the placement plate 14, ice is added to the inner cavity of the display stand 1 through the fourth groove 6. The fourth groove 6 is sealed by the rotating plate 61 to reduce the air circulation in the inner cavity of the display stand 1. The insulation cotton 12 is used to further increase the insulation effect of the inner cavity of the display stand 1. The placement plate 14 can be kept stable in the inner cavity of the display stand 1 by the cooperation of the connecting plate and the placement plate 14.

[0031] Furthermore, such as Figure 3 As shown, a storage cabinet 3 is fixedly installed on one side of the display stand 1, and a ventilation slot 31 is provided on one side of the display stand 1. The ventilation slot 31 is located between the storage cabinet 3 and the display stand 1, and a placement slot 32 is provided on one side of the storage cabinet 3.

[0032] When using this invention, since the space inside the display stand 1 is limited, and in order to add ice to the display stand 1 in a timely manner when ice is needed, ice can be placed inside the storage cabinet 3 in advance. Then, the placement slot 32 is sealed so that cold air can only diffuse into the display stand 1 through the ventilation slot 31. This can further improve the preservation effect of lychees inside the display stand 1 and slow down the rate at which the ice melts into water.

[0033] Furthermore, such as Figure 6 As shown, a first air blower 52 is fixedly installed in the inner cavity of the swing table 1, and two second air blowers 53 are fixedly installed on the outer surface of the first air blower 52. Several air outlets 54 are opened at the bottom of the second air blower 53. A fan 51 is fixedly connected to the outer surface of the first blower pipe 52, and a suction pipe 5 is fixedly connected to one side of the fan 51. One end of the suction pipe 5 extends into the inner cavity of the swing table 1.

[0034] When in use, the cold air inside the display stand 1 is drawn out by the fan 51, and then discharged into the display stand 1 through the first air pipe 52 and the second air pipe 53. This allows the cold air flow inside the display stand 1 to keep the lychees fresh in all directions.

[0035] Furthermore, such as Figure 6As shown, a water pump 41 is fixedly connected to one end of the second water pipe 244, and a filter box 4 is fixedly connected to one side of the water pump 41. The filter box 4 communicates with the inner cavity of the display stand 1.

[0036] When in use, the inner cavity of the display stand 1 contains both ice and water. The water is pumped out of the inner cavity of the display stand 1 by the water pump 41, filtered first by the filter box 4, and then enters the inner cavity of the second water pipe 244. Finally, it is sprayed onto the surface of the lychee by the nozzle 243 to preserve the lychee.

[0037] Working principle: The slider 24 slides in the inner cavity of the third groove 21. At this time, the second gear 2422 is rotated by the rack 2423. The second gear 2422 further drives the first gear 2421 to rotate. The first gear 2421 drives the first water pipe 242 to rotate to the top of the placement plate 14. Before starting, the first water pipe 242 is close to the side of the support plate 2. When in use, the first water pipe 242 slides on the top of the placement plate 14 with the slider 24. Water is delivered to the inner cavity of the first water pipe 242 through the second water pipe 244 and finally sprayed out through several nozzles 243. This can achieve the work of spraying water to keep the lychees fresh, and can also avoid water waste and spraying around the display table 1, which may cause customers to slip when they approach the display table 1.

[0038] The fan 51 extracts the cold air from the inner cavity of the display stand 1, and then the cold air is discharged into the inner cavity of the display stand 1 through the first air pipe 52 and the second air pipe 53. This allows the cold air to circulate in the inner cavity of the display stand 1 to keep the lychees fresh in all directions. The inner cavity of the display stand 1 contains ice and water. The water pump 41 extracts the water from the inner cavity of the display stand 1, filters it through the filter box 4, and then enters the inner cavity of the second water pipe 244. Finally, the water is sprayed onto the surface of the lychees by the nozzle 243 to keep the lychees fresh.
