Description

Technical Field

[0001] The present invention relates to the technical field of tofu boxes, and specifically provides a multi-layer composite structure antibacterial tofu box. Background Art

[0002] A tofu box is a special container for storing, transporting, and selling tofu. Its design and functions need to meet the requirements of tofu freshness preservation, hygiene, and convenience. It is usually rectangular or cubic in shape, with dimensions customized according to actual needs. Some boxes are internally provided with layers or partitions to facilitate the classified storage of different types or batches of tofu. It is equipped with an openable lid for easy access to the tofu. The lid is connected to the box body through buckles, locks, or hinges. Ventilation holes are provided on the side or top of the box body to adjust the internal humidity and air pressure and prevent the growth of microorganisms. Among them, a multi-layer composite structure antibacterial tofu box is a tofu box made of multi-layer composite materials, and each layer of material undertakes different functions.

[0003] For example, the Chinese patent "A Tofu Fermentation Box" with the publication number CN221204073U includes a fermentation box. An outer shell is fixedly installed on the outer wall of the fermentation box. A humidity meter is fixedly installed on the top of the fermentation box. A spray pump is fixedly installed on one outer wall of the fermentation box. A spray pipe is fixedly installed on the top of the spray pump. An air inlet is fixedly connected to the upper surface of the end of the fermentation box away from the humidity meter. A constant temperature fan is fixedly connected to the top of the air inlet. A spray port is opened on the top of the fermentation box. A nozzle is fixedly installed at the bottom of the spray port. An opening and closing door is arranged on the outer wall of the fermentation box. A handle is fixedly installed on the outer wall of the opening and closing door. A placement groove is fixedly connected to the inner wall of the fermentation box. A placement sieve plate is slidably connected to the inner wall of the placement groove. The spray pipe is connected to the spray port on the top of the fermentation box. An air inlet is fixedly connected to the upper surface of the fermentation box. The air inlet penetrates through the top of the fermentation box and is connected to the inside of the fermentation box. An air outlet is fixedly installed at the bottom of the fermentation box. A sealing cover is rotatably connected to the top of the fermentation box. An ultraviolet disinfection lamp is fixedly installed on the inner wall of the fermentation box.

[0004] Although the above-mentioned prior art can realize the use of the tofu box, in actual use, on the one hand, it is difficult to separate the tofu. Usually, the overall structure of the space position inside the box body causes the adjacent tofu to come into contact under the action of external forces, thus increasing the risk of tofu contamination. On the other hand, the disassembly and assembly of the handle are not convenient enough. Usually, the handle is fixedly arranged on both sides of the box body, which affects the handling of the box body after the handle is damaged, thereby reducing the service life of the box body. Therefore, it does not meet the existing requirements, and for this reason, we propose a multi-layer composite structure antibacterial tofu box. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) Through the vertical baffle and the horizontal baffle, the present invention can separate the tofu blocks. Before putting the tofu into the box body, the vertical baffle and the horizontal baffle are installed according to specific actual requirements. At this time, the operator presses the telescopic rod, so that the telescopic rod completely enters the inside of the telescopic cavity, and at the same time, the return spring is in a compressed state. Then the vertical baffle is placed at a suitable position inside the box body. At this time, the return spring resets, and the force generated by the reset of the return spring pushes the telescopic rod out of the telescopic cavity. At the same time, the threaded end of the telescopic rod extends out of the first ventilation hole. Then the first nut is sleeved outside the telescopic rod and rotated, so that the first nut moves outside the telescopic rod until the first nut contacts the side wall of the box body. At this time, the groove opening on the horizontal baffle is aligned with the upper end of the vertical baffle and the horizontal baffle is moved downward until the horizontal baffle is moved to a suitable position. At this time, the vertical baffle enters the groove inside the horizontal baffle. Then the bolt is aligned with the opening of the second ventilation hole and inserted into the second ventilation hole until one end of the bolt enters the threaded hole to complete the fixation of the horizontal baffle, thereby separating the space inside the box body and preventing the adjacent tofu blocks from contacting each other.

[0018] (2) Through the threaded rod and the second nut, the handle of the present invention can be quickly disassembled and assembled. When the handle needs to be replaced, first open the box cover. Then, the operator rotates the second nut, causing the second nut to move on the threaded rod until the second nut separates from the threaded rod. Next, pull the mounting seat, causing the mounting seat to drive the threaded rod to move outward in the second ventilation hole until the threaded rod disengages from the second ventilation hole. Then, align the threaded rod on the new handle with the opening of the second ventilation hole and push it into the second ventilation hole until the mounting seat is moved to a suitable position. At this time, sleeve the second nut outside the threaded rod and rotate it, causing the second nut to move outside the threaded rod until the second nut contacts the inner wall of the box body, completing the replacement of the handle. At the same time, when the box body is not in use, the handle can be removed from the box body, thereby reducing the space utilization rate of the box body.

[0019] (3) Through the ultraviolet lamp tube and the composite antibacterial layer, the antibacterial effect of the box body of the present invention can be improved. After the tofu is placed inside the box body, the ultraviolet lamp tube is powered on. At this time, the ultraviolet lamp tube disinfects and sterilizes the tofu, and the tofu stays inside the box body for more than thirty minutes. Until the tofu is transported to a suitable position, then open the box cover and take out the tofu from the box body for subsequent operations. The provided antibacterial outer layer can effectively inhibit the reproduction of microorganisms such as bacteria and molds, reducing the risk of spoilage of the tofu caused by microbial contamination and avoiding the spoilage of the tofu in the dead corner of ultraviolet irradiation. The provided antibacterial inner layer and preservation layer can effectively slow down the loss of proteins, vitamins and flavor substances in the tofu, maintaining its color, taste and nutritional value.

At the same time, the threaded end of the telescopic rod 11 extends out of the first ventilation hole 8. Then sleeve the first nut 12 outside the telescopic rod 11 and rotate it, so that the first nut 12 moves outside the telescopic rod 11 until the first nut 12 contacts the side wall of the box body 1. At this time, align the opening of the groove 21 on the horizontal baffle 18 with the upper end of the vertical baffle 17 and move the horizontal baffle 18 downward until the horizontal baffle 18 is moved to a suitable position. At this time, the vertical baffle 17 enters the groove 21 inside the horizontal baffle 18. Then align the bolt 13 with the opening of the second ventilation hole 9 and insert it into the second ventilation hole 9 until one end of the bolt 13 enters the threaded hole 23 to complete the fixation of the horizontal baffle 18, thereby separating the space inside the box body 1. When it is necessary to replace the handle 5, first open the box cover 3. At this time, the operator rotates the second nut 20 so that the second nut 20 moves on the threaded rod 19 until the second nut 20 is separated from the threaded rod 19. Then pull the mounting seat 4 so that the mounting seat 4 drives the threaded rod 19 to move outward in the second ventilation hole 9 until the threaded rod 19 disengages from the second ventilation hole 9. Then align the threaded rod 19 on the new handle 5 with the opening of the second ventilation hole 9 and push it into the second ventilation hole 9 until the mounting seat 4 is moved to a suitable position. At this time, sleeve the second nut 20 outside the threaded rod 19 and rotate it so that the second nut 20 moves outside the threaded rod 19 until the second nut 20 contacts the inner wall of the box body 1. At the same time, when the box body 1 is not in use, the handle 5 can be removed from the box body 1. When the tofu is placed inside the box body 1, at this time, the ultraviolet lamp tube 27 is powered on. At this time, the ultraviolet lamp tube 27 disinfects and sterilizes the tofu, and the tofu stays inside the box body 1 for more than thirty minutes. Until the tofu is transported to a suitable position, at this time, open the box cover 3 and take out the tofu from the box body 1 for subsequent operations.
