[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] like Figures 1-5 As shown, a storage box for tsampa food includes a box body 1 and a storage lid 2. A desiccant storage cylinder 6 is fixedly connected through the storage lid 2. Multiple ventilation holes 12 are circumferentially opened on the side of the desiccant storage cylinder 6 near the bottom of the storage lid 2. A screw cap 5 is threadedly connected to the inner side of the opening of the desiccant storage cylinder 6. Multiple connecting rods 18 arranged in a ring array are fixedly connected to the flange of the screw cap 5. A vent plate 13 is fixedly connected to the bottom of the connecting rods 18. The side of the vent plate 13 is sealed to the desiccant storage cylinder 6 by an O-ring. An alloy box 14 for holding tsampa food is provided inside the box body 1. The alloy box 14 and the box body 1 are fitted with a gap. The gap between the alloy box 14 and the box body 1 is filled with a heat insulation plate 16. A sealing strip 19 is embedded in the outer side of the flange of the storage lid 2.

[0026] In this technical solution, the desiccant storage cylinder 6, the vent 12, the screw cap 5, the connecting rod 18, the vent plate 13, and the O-ring work together to achieve convenient replacement and effective sealing of the desiccant. By unscrewing the screw cap 5, the screw cap 5 is removed from the opening of the desiccant storage cylinder 6, thereby driving the vent plate 13 out of the desiccant storage cylinder 6 through the connecting rod 18. The desiccant can then be poured directly into the desiccant storage cylinder 6 to replace the desiccant inside. Compared with the existing technology that requires the replacement of the entire food storage box and internal drying frame, the operation is much simpler. Granular silica gel desiccant can be used as the desiccant.

[0027] By setting up the alloy box 14, initial heat insulation can be achieved. The alloy box 14 is used to hold tsampa food. It fits the box body 1 with a gap, and the gap is filled with a heat insulation board 16 to further reduce the impact of external temperature on the tsampa food inside the box, playing a good heat insulation role and helping to maintain the quality of tsampa food. The sealing strip 19 embedded on the outer side of the flange of the storage lid 2 enhances the sealing of the storage box, further preventing external air and moisture from entering the box, and better protecting the tsampa food from oxidation and moisture deterioration.

[0028] In addition, the alloy box 14 can be made of 304 stainless steel or aluminum alloy. 304 stainless steel has good corrosion resistance and can effectively resist the corrosion of acidic or alkaline substances that may be generated during the storage of tsampa food. Aluminum alloy is lighter, which reduces the weight of the entire storage box and makes it easier to handle and move.

[0029] like Figure 3 As shown, an installation frame 17 is fixedly connected to the outside of the alloy box 14 near the box opening. A limit frame 3 is provided on the top of the installation frame 17. One side of the limit frame 3 abuts against the alloy box 14 and the other side abuts against the box body 1. Fixing bolts 4 pass through all four sides of the box body 1 and are threadedly connected to the limit frame 3.

[0030] In this technical solution, the mounting frame 17, the limiting frame 3, and the fixing bolt 4 work together to play a key role in stabilizing the alloy box 14. The mounting frame 17 is fixed on the outside of the alloy box 14 near the box opening, providing a mounting base for the limiting frame 3. The limiting frame 3 is sandwiched between the alloy box 14 and the box body 1, with its two sides abutting against both of them. This effectively restricts the position of the alloy box 14 within the box body 1, preventing the alloy box 14 from shaking or shifting during use, and ensuring the stability of the storage box structure.

[0031] By inserting fixing bolts 4 through the four sides of the housing 1 and threading them to the limiting frame 3, when the operator needs to fix the alloy box 14, tightening the fixing bolts 4 can increase the squeezing force of the limiting frame 3 on the alloy box 14 and the housing 1, thereby fixing the alloy box 14 more firmly; when it is necessary to disassemble or adjust the alloy box 14, loosening the fixing bolts 4 can easily remove or move the alloy box 14.

[0032] like Figure 3 As shown, an air extraction frame 10 is fixedly connected to one side of the housing 1. An electric air extraction fan 15 is installed inside the air extraction frame 10. The air inlet of the electric air extraction fan 15 passes through the housing 1, the insulation plate 16 and the alloy box 14 and extends into the alloy box 14.

[0033] In this technical solution, the installation of the air extraction frame 10 and the electric air extraction fan 15 further optimizes the storage environment of tsampa. By installing the electric air extraction fan 15, the connection between the air inlet of the electric air extraction fan 15 and the alloy box 14 is sealed with a rubber sealing gasket. The electric air extraction fan 15 can extract the air from the alloy box 14, creating a relatively vacuum environment inside the box. This allows the storage box to effectively reduce the oxygen content, inhibit the growth and reproduction of aerobic microorganisms and the oxidation reaction of tsampa, and extend the shelf life of tsampa. On the other hand, it reduces the humidity inside the box, preventing the tsampa from becoming damp and clumping, thus maintaining its good taste and quality.

[0034] Furthermore, the extraction frame 10 protects and secures the electric vacuum pump 15, allowing it to be firmly installed on one side of the housing 1, while also facilitating the maintenance and repair of the electric vacuum pump 15.

[0035] like Figure 2 As shown, storage cavities 11 are provided on both sides of the box body 1 and below the alloy box 14, and storage drawers 7 are slidably connected in the storage cavities 11.

[0036] In this technical solution, the alloy box 14 for holding tsampa is separated from the storage area of ​​other items through a layered design, making the classification clear and convenient for users to organize and find items.

[0037] In addition, the storage drawer 7 is slidably connected to the storage cavity 11, making it convenient for users to take out and store items. Users can put items such as ghee, milk residue, sugar and other seasonings that are eaten with tsampa, or tableware for holding tsampa, into the storage drawer 7.

[0038] like Figure 1 As shown, a pull rod 9 is rotatably connected to one side of the box body 1.

[0039] In this technical solution, by setting a pull rod 9, the storage box has a draggable function similar to a suitcase. When it is necessary to move the storage box, the user can hold the pull rod 9 and pull it up to change the angle between the pull rod 9 and the box body, so that the storage box can be pulled forward in a more comfortable posture.

[0040] like Figure 2 As shown, the bottom of the box 1 is equipped with rollers 8.

[0041] In this technical solution, the rollers 8 facilitate the movement of the storage box, thereby improving its ease of use.

[0042] Working principle: When using this tsampa food storage box, first place the tsampa into the alloy box 14. The insulation plate 16 between the alloy box 14 and the box body 1 reduces the influence of external temperature and maintains the quality of the tsampa. Next, if the desiccant needs to be replaced, unscrew the screw cap 5, and use the connecting rod 18 to remove the vent plate 13. Pour the granular desiccant into the desiccant storage cylinder 6, and then rotate and install it again to confine the desiccant between the vent plate 13 and the bottom surface of the desiccant storage cylinder 6. The desiccant can absorb moisture inside the box through the vent holes 12, preventing moisture buildup. If the tsampa gets damp, close the storage lid 2. The sealing strip 19 on the outer side of the flange of the storage lid 2 enhances the airtightness. To keep it fresh, start the electric vacuum pump 15, which extracts the air from the alloy box 14 to create a relative vacuum environment, inhibiting the growth of microorganisms and oxidation of the tsampa, and reducing humidity. In daily use, seasonings, tableware, etc. can be placed in the storage drawer 7 for easy access. If you need to move the storage box, pull up the lever 9 and use the bottom rollers 8 to move it easily. The entire device achieves effective preservation and convenient use of tsampa through these processes.

[0043] The wiring diagram of the electric vacuum pump 15 in this utility model is common knowledge in the field. Its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the electric vacuum pump 15 will not be explained in detail.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
