It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figures 1 - 4As shown in the figure, the utility model provides a vacuum barrel dedicated for fresh litchi preservation, including: an outer barrel 1, a first partition layer 2 fixedly connected to the inner surface of the outer barrel 1, a second partition layer 3 fixedly connected to the inner surface of the outer barrel 1 near the inner side of the first partition layer 2, a bottom plate 7 fixedly connected to the inner bottom of the outer barrel 1, and an air valve 6 fixedly connected to the outer surface of the outer barrel 1; a storage assembly 5, the storage assembly 5 is located inside the outer barrel 1, the storage assembly 5 includes a top cover 501, a support rod 503 fixedly connected to the bottom of the top cover 501, a plurality of placement frames 504 fixedly connected to the outer surface of the support rod 503 at equal intervals, a filter plate 505 fixedly connected to the inner surface of the placement frame 504, a drain pipe 506 fixedly connected through between the plurality of placement frames 504 and the plurality of filter plates 505, a plurality of notches 507 are equidistantly opened on the outer surface of the drain pipe 506, there is a certain distance between the filter plate 505 and the inner bottom of the placement frame 504, the notches 507 are located between the filter plate 505 and the inner bottom of the placement frame 504, a jack 8 is opened on the top of the bottom plate 7, the support rod 503 is matched with the position of the jack 8, a water collecting box 9 is fixedly connected to the top of the bottom plate 7, a drain valve 10 is fixedly connected to the outer surface of the water collecting box 9, a cover plate 11 is fixedly connected to the top of the water collecting box 9, and a through hole is opened on the top of the cover plate 11, and the through hole is matched with the position of the drain pipe 506.

[0024] The effect achieved by the entire embodiment 1 is that when using the vacuum barrel to preserve and store litchi, the inside of the outer barrel 1 is divided into three spaces by the first partition layer 2 and the second partition layer 3. The space between the first partition layer 2 and the inner wall of the outer barrel 1 can be evacuated to a vacuum state. Due to the temperature insulation of the inside of the barrel, ice cubes can be stored between the first partition layer 2 and the second partition layer 3 for low-temperature preservation and storage of litchi. The inside of the second partition layer 3 is used to store litchi. The vacuum layer and the ice cube layer play a good role in preserving and storing litchi. After taking out the top cover 501, the support rod 503 and the placement frame 504 are taken out. The litchi can be laid flat in multiple placement frames 504 in layers. After the litchi is put into the placement frame 504, the bottom filter plate 505 provides support for the litchi. Through the arrangement of a plurality of filter holes on the surface of the filter plate 505, when the litchi is stored at low temperature inside the vacuum barrel, the water vapor generated by the low temperature will condense into water droplets on the surface of the litchi, and the water droplets will drip through the filter holes to the bottom position of the placement frame 504. The accumulated water at the bottom of the placement frame 504 will enter the drain pipe 506 through the notches 507, and the water flowing through the drain pipe 506 will enter the water collecting box 9 for storage. Opening the drain valve 10 can drain the collected water. Through the arrangement of filtering water for the litchi by the filter plate 505 and draining and collecting water by the drain pipe 506, the litchi is always stored in a relatively dry state, which can prevent the surface or branches and leaves of the litchi from accumulating water and affecting its freshness, and improves the preservation effect of the litchi.

[0025] Embodiment 2, as Figures 1 - 4As shown, a plurality of positioning holes 12 are evenly formed at the top of the outer barrel 1, and a plurality of positioning rods 508 are evenly and fixedly connected to the bottom of the top cover 501. The outer surface of the positioning rod 508 is inserted and connected to the inner surface of the positioning hole 12. A threaded sleeve 4 is threadedly connected to the outer surface of the outer barrel 1, and the inner surface of the threaded sleeve 4 is threadedly connected to the outer surface of the top cover 501. A convex block 502 is fixedly connected to the top of the top cover 501.

[0026] The effect achieved by the entire Embodiment 2 is that when the top cover 501 is covered above the outer barrel 1, the cooperation of the positioning hole 12 and the positioning rod 508 can play a positioning role, so that the top cover 501 is inserted at a fixed position. The drain pipe 506 can be accurately inserted into the through hole to be spliced with the water collecting box 9. After covering the top cover 501, the threaded sleeve 4 is screwed to move upward. The threaded sleeve 4 can be sleeved between the outer barrel 1 and the top cover 501 for fixation. The fixation operation of the top cover 501 is relatively convenient and fast.

[0027] Working principle: When using the vacuum barrel to store litchis for freshness preservation, the interior of the outer barrel 1 is divided into three spaces by the first partition layer 2 and the second partition layer 3. The space between the first partition layer 2 and the inner wall of the outer barrel 1 can be evacuated to a vacuum state. Due to the temperature insulation of the interior of the barrel, ice cubes can be stored between the first partition layer 2 and the second partition layer 3 for low-temperature freshness preservation storage of litchis. The interior of the second partition layer 3 is used to store litchis. The vacuum layer and the ice cube layer can achieve a good freshness preservation storage effect on litchis. After taking out the top cover 501, the support rod 503 and the placement frame 504 are taken out. The litchis can be laid flat in multiple placement frames 504 in layers. After the litchis are placed in the placement frame 504, the filter plate 505 at the bottom provides support for the litchis. Through the arrangement of a plurality of filter holes on the surface of the filter plate 505, when the litchis are stored at low temperature inside the vacuum barrel, the water vapor generated by the low temperature will condense into water droplets on the surface of the litchis, and the water droplets will drip through the filter holes to the bottom position of the placement frame 504. The accumulated water at the bottom of the placement frame 504 will enter the drain pipe 506 through the notch 507, and the water flowing through the drain pipe 506 will enter the water collecting box 9 for storage. Opening the drain valve 10 can drain the collected water. Through the arrangement of filtering water for the litchis by the filter plate 505 and draining and collecting water by the drain pipe 506, the litchis can always be stored in a relatively dry state, which can prevent the surface or branches and leaves of the litchis from accumulating water and affecting their freshness, and improves the freshness preservation effect on litchis. When the top cover 501 is covered above the outer barrel 1, the cooperation of the positioning hole 12 and the positioning rod 508 can play a positioning role, so that the top cover 501 is inserted at a fixed position. The drain pipe 506 can be accurately inserted into the through hole to be spliced with the water collecting box 9. After covering the top cover 501, the threaded sleeve 4 is screwed to move upward. The threaded sleeve 4 can be sleeved between the outer barrel 1 and the top cover 501 for fixation. The fixation operation of the top cover 501 is relatively convenient and fast.

[0028] The above are only the preferred embodiments of the present utility model, and do not limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above 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 utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
