Description

Technical Field

[0001] This utility model belongs to the field of food preservation technology, and in particular relates to a dynamic food preservation chamber structure based on multi-layer vacuum negative pressure. Background Technology

[0002] As people's living standards improve and their attention to food safety and quality increases, food preservation technology is becoming increasingly crucial in daily life and the food industry. The dynamic food preservation chamber structure based on multi-layer vacuum negative pressure has received widespread attention and application in the field of food preservation because it can effectively extend the shelf life of food and maintain its freshness and nutritional components.

[0003] However, the existing refrigeration compartment structure is not easy to adjust the spacing between the compartments during use, making it difficult to provide sufficient space for the food. The fixed space will cause large-volume food to be squeezed, resulting in damage and spoilage, thus causing losses. Utility Model Content

[0004] The purpose of this invention is to provide a dynamic food preservation chamber structure based on multi-layer vacuum negative pressure. By setting an adjustable partition mechanism, it solves the problem that existing food preservation chamber structures are not easy to adjust the partition spacing during use, making it difficult to provide sufficient space for food. Fixed space can cause large-volume food to be squeezed, resulting in damage and spoilage, thus causing losses.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a dynamic food preservation chamber structure based on multi-layer vacuum negative pressure, including a preservation chamber, on which an adjustable partition mechanism and a locking mechanism are provided.

[0007] The adjustable partition mechanism includes two hinged blocks 1 fixedly connected to the inner wall of the bottom of the refrigeration compartment. Each of the two hinged blocks 1 is hinged with a hinge rod 1. The top of each of the two hinge rods 1 is hinged with a hinged block 2. A connecting block is fixedly connected between the two hinged blocks 2. An electric telescopic rod is fixedly connected between the two connecting blocks. Each of the two hinged blocks 2 is hinged with a hinge rod 2. The locking mechanism includes a sealing door hinged to the front side of the refrigeration compartment. The top of each of the two hinge rods 2 is hinged with a hinged block 3. A breathable partition is fixedly connected to the top of each of the two hinged blocks 3.

[0008] Furthermore, rectangular sliding rods are fixedly connected to the inner walls of the left and right sides of the preservation compartment. Both rectangular sliding rods pass through the air-permeable partition and are slidably connected to the air-permeable partition. An air outlet pipe is provided on the right side of the preservation compartment. Two rectangular sliding grooves are opened on the front side of the preservation compartment, and rectangular sliders are slidably connected to the inner walls of the two rectangular sliding grooves.

[0009] Furthermore, a rectangular box is fixedly connected to the front side of each of the two rectangular sliders, and a rectangular slider is slidably connected to the inner wall of each of the two rectangular boxes. A Z-shaped connecting block is fixedly connected to the side of each of the two rectangular sliders that are close to each other, and a rectangular limiting rod is fixedly connected to the rear side of each of the two Z-shaped connecting blocks.

[0010] Furthermore, handles are fixedly connected to the right side of the two rectangular boxes, and spring telescopic rods are fixedly connected to the front side of the two rectangular sliders. The front side of the two spring telescopic rods is fixedly connected to the rectangular boxes. Limiting grooves are opened on the side of the two rectangular boxes that are close to each other. The inner walls of the two limiting grooves are slidably connected to two Z-shaped connecting blocks respectively. Two latches are fixedly connected to the front side of the preservation compartment. The two latches are adapted to the rectangular limiting rods.

[0011] This utility model has the following beneficial effects:

[0012] 1. By setting an adjustable partition mechanism, when in use, the air outlet pipe is connected to the vacuum pump to extract the air from the preservation compartment, achieving a vacuum preservation effect. When adjusting the height of the breathable partition, the electric telescopic rod is activated. The electric telescopic rod extends, which drives the two hinge blocks two to move away from each other through the two connecting blocks. Then, the two hinge blocks two drive the two hinge rods one and two hinge rods two to rotate. This, in turn, drives the breathable partition to move upward under the limit of the rectangular sliding rod through the two hinge blocks three. Similarly, controlling the electric telescopic rod to retract will drive the breathable partition to descend. This allows the height of the breathable partition to be adjusted to adjust the partition spacing, thereby providing sufficient space for the food, avoiding damage and spoilage caused by compression, and ensuring that all kinds of food can be properly preserved in a suitable space.

[0013] 2. By setting up a locking mechanism, when opening the sealed partition door, pull the handle to the right. The handle moves the two rectangular boxes to the right, which in turn moves the two Z-shaped connecting blocks to the right. This causes the rectangular limit rod to move to the right. The rectangular limit rod is squeezed forward by the two locks, which in turn moves the two Z-shaped connecting blocks forward under the limit of the two limit slides. The two rectangular sliders then move forward within the two rectangular boxes, compressing the two spring telescopic rods until the rectangular limit rod separates from the two locks, thus opening the sealed partition door. To close and lock the sealed partition door, simply close the sealed partition door first, then push the handle back to reset. Through a similar process, the rectangular limit rod will lock the locks, thus locking the sealed partition door. This prevents the sealed partition door from opening accidentally, avoiding damage to the vacuum negative pressure environment inside the chamber and protecting the food from external contamination during equipment operation due to external impacts or other factors.

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.

[0024] Please see Figure 1-5As shown, this utility model is a dynamic food preservation chamber structure based on multi-layer vacuum negative pressure, including a preservation chamber 1. The preservation chamber 1 is equipped with an adjustable partition mechanism 2 and a locking mechanism 3. The adjustable partition mechanism 2 includes two hinge blocks 211 fixedly connected to the inner wall of the bottom of the preservation chamber 1. Each of the two hinge blocks 211 is hinged with a hinge rod 212. The top of each of the two hinge rods 212 is hinged with a second hinge block 213. A connecting block 214 is fixedly connected between the two hinge blocks 213. An electric telescopic rod 215 is fixedly connected between the two connecting blocks 214. Each of the two hinge blocks 213 is hinged with a second hinge rod 216. The top of each hinge rod 216 is hinged with a hinge block 217. The top of each hinge block 217 is fixedly connected with a breathable partition 218. The left and right inner walls of the preservation compartment 1 are fixedly connected with rectangular slide rods 219. Both rectangular slide rods 219 pass through the breathable partition 218 and are slidably connected to the breathable partition 218. The right side of the preservation compartment 1 is connected to an air outlet pipe 111. By setting an adjustable partition mechanism 2, the partition height can be adjusted to adjust the partition spacing, thereby providing sufficient space for food, avoiding damage and spoilage caused by compression, and ensuring that all kinds of food can be properly preserved in a suitable space.

[0025] The locking mechanism 3 includes a sealed partition 311 hinged to the front of the refrigeration compartment 1. Two rectangular slides 312 are provided on the front of the refrigeration compartment 1. Rectangular sliders 313 are slidably connected to the inner walls of both rectangular slides 312. Rectangular boxes 314 are fixedly connected to the front of each of the two rectangular sliders 313. Rectangular sliders 315 are slidably connected to the inner walls of each of the two rectangular boxes 314. Z-shaped connecting blocks 316 are fixedly connected to the sides of the two rectangular sliders 315 that are close to each other. Rectangular limiting rods 317 are fixedly connected to the rear sides of the two Z-shaped connecting blocks 316. Handles 318 are fixedly connected to the right sides of the two rectangular boxes 314. Rectangular sliders 315 are fixedly connected to the front sides of the two rectangular sliders 315. The equipment is connected to spring telescopic rods 319. The front sides of the two spring telescopic rods 319 are fixedly connected to rectangular boxes 314. Limiting grooves 3110 are opened on the side of the two rectangular boxes 314 that are close to each other. The inner walls of the two limiting grooves 3110 are slidably connected to two Z-shaped connecting blocks 316 respectively. Two latches 3111 are fixedly connected to the front side of the preservation compartment 1. The two latches 3111 are adapted to the rectangular limiting rods 317. By setting the latch mechanism, the sealed partition door 311 can be prevented from being opened accidentally. This prevents the sealed partition door from being opened due to external force collision or other factors during the operation of the equipment, thereby preventing the vacuum negative pressure environment inside the compartment from being damaged and protecting the food from external contamination.

[0026] A specific application of this embodiment is as follows: In use, connecting the air outlet pipe 111 to the vacuum pump allows air to be extracted from the preservation chamber 1, achieving a vacuum preservation effect. When adjusting the height of the venting partition 218, the electric telescopic rod 215 is activated. The electric telescopic rod 215 extends, thereby driving the two hinge blocks 213 away from each other through the two connecting blocks 214. Consequently, the two hinge blocks 213 drive the two hinge rods 212 and 216 to rotate, thereby driving the venting partition 218 to move upward under the limit of the rectangular slide rod 219 through the two hinge blocks 217. Similarly, controlling the retraction of the electric telescopic rod 215 will drive the venting partition 218 to descend. When opening the sealing door 311, pulling the handle 318 to the right causes the handle 318 to drive the two rectangular boxes 314 to move upward. Moving to the right, the two rectangular boxes 314 drive the two Z-shaped connecting blocks 316 to move to the right, thereby driving the rectangular limiting rod 317 to move to the right. The rectangular limiting rod 317 is pushed forward by the lateral pressure of the two latches 3111, thereby driving the two Z-shaped connecting blocks 316 to move forward under the limitation of the two limiting slide grooves 3110 respectively. The two rectangular sliders 315 then move forward in the two rectangular boxes 314, compressing the two spring telescopic rods 319 until the rectangular limiting rod 317 separates from the two latches 3111, thus opening the sealing partition door 311. To close and lock the sealing partition door 311, simply close the sealing partition door 311 first, and then push the handle 318 to reset. Through the above similar process, the rectangular limiting rod 317 can be locked with the latches 3111, thereby locking the sealing partition door 311.
