Description

Technical Field

[0001] This utility model relates to the field of preservation equipment technology, specifically to a semi-sealed cover for a vacuum meat storage and preservation device. Background Technology

[0002] Vacuum preservation equipment is a device that maintains the freshness of food by creating a vacuum. It mainly consists of a compressor (or vacuum pump), a vacuum container (or packaging bag), a sealing system, and a control system. Currently, vacuum preservation equipment is commonly used for storing meat during transportation.

[0003] Utility model patent application number 202420544404.6 discloses a meat product preservation device, which includes a storage mechanism, a preservation mechanism, and a space adjustment mechanism. The preservation mechanism is installed on the storage mechanism, and the space adjustment mechanism is installed inside the storage mechanism. The space adjustment mechanism adjusts the size of the storage space, and the preservation mechanism works in conjunction with the storage mechanism to preserve the meat products. When the meat products are placed in the storage mechanism, the air inside the storage mechanism is expelled by the preservation mechanism. Due to the negative pressure environment created inside the storage mechanism, the space adjustment mechanism moves upward, reducing the storage space within the storage mechanism, allowing the meat products to be vacuum-stored in a suitable space, thereby improving the practicality of the equipment.

[0004] Although this meat preservation equipment allows for easy adjustment of storage space, it still has the following problems in practical use: the current sealing lid is only connected to the cabinet via a hinge, lacking an auxiliary fixing structure. Under conditions of transportation vibration, frequent handling, or external impact, the lid is prone to accidental opening, leading to cold air leakage and disruption of the vacuum environment, directly affecting the preservation effect of fresh meat. Therefore, we propose a semi-sealed lid for the vacuum meat storage and preservation equipment. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this utility model is to provide a semi-sealed cover for a vacuum meat storage and preservation device. Through the insertion and engagement of the fixing rod and the fixing hole, the cover can be stably kept closed, preventing accidental opening of the cover, which could lead to cold air leakage, disruption of the vacuum environment, and directly affect the preservation effect of the fresh meat.

[0006] To achieve the above objectives, this utility model provides the following technical solution: The semi-sealed cover of the vacuum meat storage and preservation equipment includes a cabinet body. The top of the cabinet body has two cavities. A connecting groove is provided near the middle of the top of the cabinet body. A limit plate is fixed at the edge of the top of the cabinet body.

Two connecting blocks that are hinged to the connecting groove are fixed at one end of the sealing cover. A sliding groove is provided at one corner of the outer wall of the sealing cover. A slider is slidably installed in the sliding groove. A sliding hole is provided at one end of the slider. A guide rod is slidably installed at the sliding hole. The end of the guide rod is fixedly connected to the inner wall of the sliding groove. A spring is sleeved on the outside of the guide rod to press against the slider. A fixing rod is fixed at the end of the slider away from the sliding hole. The end of the fixing rod passes through the sealing cover and is inserted into the corresponding fixing hole.

[0007] In addition, the semi-sealed cover of the vacuum meat storage and preservation device proposed in the application may also have the following additional technical features: Specifically, a sealing strip is fixed to the bottom of the sealing cover, and the sealing strip is tightly bonded to the bottom of the sealing cover.

[0008] Specifically, the slider and the fixing rod are integrally formed structures, and both the slider and the fixing rod are made of stainless steel.

[0009] Specifically, each of the sealing caps has a handle fixed to its top, and the handle is fixedly connected to the sealing cap by bolts.

[0010] Specifically, the bottom of the sealing cap is provided with an odor-removing part, which includes a box body with an open top. The outer wall of the box body has multiple air holes. An odor-removing layer is provided inside the top opening of the box body. Two side plates are provided on both sides of the box body. The top of the side plates is fixed to the bottom of the sealing cap. A clip is fixed at the bottom of one side wall of each side plate. The outer wall of the box body fits against the inner wall of the side plate, and the clip is pressed against the bottom of the box body.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0016] Please see Figures 1-4 As shown, the semi-sealed cover of the vacuum meat storage and preservation equipment includes a cabinet body 1. The top of the cabinet body 1 has two cavities 10. A connecting groove 11 is provided near the middle of the top of the cabinet body 1. A limiting plate 12 is fixed at the edge of the top of the cabinet body 1. A fixing hole 120 is provided at one corner of the inner wall of the limiting plate 12. A sealing cover 2 is provided above the cavity 10.

A sliding groove 23 is provided at one corner of the outer wall of the sealing cover 2. A slider 26 is slidably installed in the sliding groove 23. A sliding hole 260 is provided on one end face of the slider 26. A guide rod 24 is slidably installed at the sliding hole 260. The end of the guide rod 24 is fixedly connected to the inner wall of the sliding groove 23. A spring 25 for pressing the slider 26 is sleeved on the outside of the guide rod 24. A fixing rod 27 is fixed at the end of the slider 26 away from the sliding hole 260. The end of the fixing rod 27 passes through the sealing cover 2 and is inserted into the corresponding fixing hole 120.

[0017] In this embodiment, a sealing strip 21 is fixed to the bottom of the sealing cover 2, and the sealing strip 21 is tightly bonded to the bottom of the sealing cover 2. This design ensures good sealing performance of the sealing cover 2, effectively preventing air and moisture from entering, maintaining the vacuum state inside the vacuum preservation equipment, and extending the shelf life of food.

[0018] In this embodiment, the slider 26 and the fixing rod 27 are integrally formed structures, and both the slider 26 and the fixing rod 27 are made of stainless steel. The integrally formed structure of the slider 26 and the fixing rod 27 has better connection strength, ensuring the reliability and stability of the connection between the slider 26 and the fixing rod 27; the choice of stainless steel ensures its corrosion resistance and durability.

[0019] In this embodiment, a handle 20 is fixed to the top of each sealing cover 2, and the handle 20 is fixedly connected to the sealing cover 2 by bolts. The handle 20 makes it easy for the user to open and close the sealing cover 2, improving the convenience of operation.

[0020] It should be added that a dial hole 261 is provided on one side wall of the slider 26 in this embodiment. The dial hole 261 facilitates the adjustment of the horizontal position of the slider 26, thereby facilitating the opening and closing of the sealing cover 2. In practical use, the user first flips the sealing cover 2 and pushes the slider 26 to one side. The slider 26 then moves the fixing rod 27, which retracts into the sealing cover 2. At the same time, the sliding hole 260 slides along the guide rod 24, and the spring 25 is compressed by the slider 26. When the sealing cover 2 flips to a horizontal position, the sealing strip 21 is in contact with the top of the cabinet 1. At the same time, the user releases the slider 26. Under the elastic action of the spring 25, the slider 26 moves the fixing rod 27 horizontally, and the fixing rod 27 is inserted into the fixing hole 120. The sealing cover 2 is then fixed to the limiting plate 12, and the sealing cover 2 is thus fixed. Please see Figures 5-6 As shown, this embodiment provides the following technical solution based on embodiment 1: The bottom of the sealing cover 2 is provided with a deodorizing part 3, the deodorizing part 3 includes a box body 30 with an open top, the outer wall of the box body 30 is provided with multiple air holes, the top opening of the box body 30 is provided with a deodorizing layer 31, and two side plates 32 are provided on both sides of the box body 30. The top of the side plate 32 is fixed to the bottom of the sealing cover 2, and a clip 320 is fixed at the bottom of one side wall of the side plate 32. The outer wall of the box body 30 is in contact with the inner wall of the side plate 32, and the clip 320 is pressed against the bottom of the box body 30.

[0021] The above design effectively absorbs and removes odors from inside the vacuum preservation equipment, maintaining the original flavor and freshness of food.

[0022] In this embodiment, the clip 320 and the side plate 32 are integrally molded structures, both made of plastic. The integral molding structure enhances the stability and durability of the structure. The choice of plastic material reduces the overall weight, and the snap-fit ​​method for securing the box 30 improves the ease of assembly and disassembly of the box 30.

[0023] In this embodiment, protruding ribs 300 are fixed near the two corners of the outer wall of the box body 30, and the side plate 32 is located between two adjacent protruding ribs 300 and abuts against the side plate 32. The protruding ribs 300 play a limiting role in the installation of the box body 30, ensuring the stability and convenience of the installation of the box body 30.

[0024] It is understood that the deodorizing layer 31 in this embodiment is activated carbon particles. Activated carbon particles have a large specific surface area due to their porous structure, which can efficiently adsorb and remove odor molecules inside the vacuum preservation equipment, such as pollutants like formaldehyde, benzene, and TVOC, as well as various unpleasant odors produced by food.
