Description

Technical Field

[0001] This utility model belongs to the field of preservation technology, and in particular relates to a fruit and vegetable preservation device. Background Technology

[0002] Fruit and vegetable preservation devices are used to extend the shelf life of fruits and vegetables and maintain their freshness and nutritional value. They mainly achieve the preservation effect by controlling environmental factors such as temperature, humidity and gas composition. Common fruit and vegetable preservation devices include sealed food storage boxes, which work by physically isolating the produce to slow down oxidation and reduce internal moisture evaporation.

[0003] Based on the above, the inventors have discovered the following shortcomings in existing fruit and vegetable preservation devices:

[0004] 1. The sealing strip of the food storage container is solid, which makes it less able to deform under stress, easily affecting the sealing performance of the food storage container. It is not convenient to make the sealing strip hollow airbag type to increase the deformation sealing effect.

[0005] 2. The food storage container and lid are designed to snap together, which makes it difficult to open the lid and can easily damage the container and lid. It is not convenient to add a closing mechanism to the food storage container to prevent damage when opening. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a fruit and vegetable preservation device. It solves the problem that existing food storage containers use solid sealing strips, resulting in poor deformation under stress, which easily affects the container's sealing performance. It is inconvenient to design the sealing strip as a hollow airbag to improve the deformation sealing effect. Furthermore, the food storage container and lid use a press-fit mechanism, making opening the lid difficult and potentially damaging to both the container and lid. It is also inconvenient to add closure measures to the food storage container to prevent damage during opening.

[0007] The purpose and effectiveness of this utility model fruit and vegetable preservation device are achieved by the following specific technical means:

[0008] A fruit and vegetable preservation device includes a device body; the device body is provided with a fruit and vegetable preservation box, the top end face of the fruit and vegetable preservation box is provided with an embedding groove, the top of the left and right end faces of the fruit and vegetable preservation box is provided with a force plate, the top of the force plate of the fruit and vegetable preservation box is provided with a semi-circular head with front and rear through holes, the top end face of the force plate of the fruit and vegetable preservation box is provided with a left and right through limiting groove, and a sealing airbag strip is embedded in the embedding groove of the fruit and vegetable preservation box, the sealing airbag strip is a rounded frame-shaped tubular structure.

[0009] Furthermore, a bearing-loaded circular plate is mounted on the fixing column of the sealing clamping rod via a bearing, and a bearing groove is provided at the center of the top end face of the bearing-loaded circular plate.

[0010] Furthermore, a sealing clamping rod is installed inside the threaded hole of the flip-up strip plate. The outer circumference of the sealing clamping rod is threaded. A fixing post is provided on the bottom end face of the sealing clamping rod, and a rotating circular plate with anti-slip groove is provided on the top end face of the sealing clamping rod.

[0011] Furthermore, a closing anti-detachment rod is installed inside the internal threaded cylinder of the flipping strip plate, and a threaded rod is provided behind the closing anti-detachment rod. A circular ring with vertical penetration is provided at the front end of the threaded rod of the closing anti-detachment rod.

[0012] Furthermore, a flip-up strip plate is installed inside the limiting groove on the left side of the fruit and vegetable preservation box via a fixed shaft. A flip-up cylinder in the front-to-back direction is provided at the left end of the flip-up strip plate, and an internally threaded cylinder in the front-to-back direction is provided at the right end of the flip-up strip plate. A threaded hole that runs through the top and bottom is opened in the middle of the flip-up strip plate.

[0013] Furthermore, a fruit and vegetable preservation lid is inserted into the embedding groove of the fruit and vegetable preservation box, and an insertion strip is provided around the bottom end face of the fruit and vegetable preservation lid.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The air-filled sealing strip is easily embedded in the groove of the fruit and vegetable preservation box. It is convenient to squeeze the air-filled sealing strip through the insertion strip of the fruit and vegetable preservation lid to achieve a seal. This solves the problem that the sealing strip of the preservation box is solid, which results in poor deformation ability of the sealing strip and easily affects the sealing performance of the preservation box. It is also inconvenient to make the sealing strip into a hollow air-filled type to increase the deformation sealing effect.

[0016] The convenient flip-up strip is mounted on the fruit and vegetable preservation box via a fixed shaft for easy flipping. The flip-up strip is easily closed and prevented from detaching via a closing anti-detachment rod. The flip-up strip also supports the sealing pressure rod and the force-bearing circular plate. The sealing pressure rod descends and presses the fruit and vegetable preservation lid against the force-bearing circular plate to achieve closure. This solves the problem of the preservation box and lid being a press-fit type, which makes opening the lid difficult and prone to damage, and makes it inconvenient to add closure measures to the preservation box to prevent damage during opening.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0025] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0026] This utility model provides a fruit and vegetable preservation device, including a device body 1; the device body 1 is provided with a fruit and vegetable preservation box 2 for convenient storage of fruits and vegetables. An embedding groove is formed around the top end face of the fruit and vegetable preservation box 2 to facilitate the embedding of a sealing airbag strip 3. Force-bearing plates are provided at the top center of both the left and right end faces of the fruit and vegetable preservation box 2 to facilitate the installation and force bearing of the flip-over strip plate 5. The top of the force-bearing plate of the fruit and vegetable preservation box 2 is provided with a semi-circular head with front and rear through holes to facilitate the installation of the flip-over strip plate 5 via a fixed shaft, and also to facilitate the insertion of the closing anti-detachment rod 6. A left-right through-groove limiting groove is provided in the middle of the end face to facilitate the placement of the flip-up strip plate 5 into the limiting position. A sealing airbag strip 3 is embedded in the embedding groove of the fruit and vegetable preservation box 2, which facilitates the deformation of the sealing airbag strip 3 under force to achieve a seal. The sealing airbag strip 3 is a rounded frame-shaped tubular structure, which facilitates its fit with the embedding groove of the fruit and vegetable preservation box 2 and increases the deformation sealing effect. A fruit and vegetable preservation lid 4 is inserted into the embedding groove of the fruit and vegetable preservation box 2 to facilitate the sealing of the fruit and vegetable preservation box 2. An insertion strip is provided around the bottom end face of the fruit and vegetable preservation lid 4 to facilitate the compression of the sealing airbag strip 3.

[0027] The fruit and vegetable preservation box 2 has a rotating strip plate 5 installed inside the limiting groove on the left side via a fixed shaft, facilitating its opening and closing. A rotating cylinder in the front-to-back direction is located at the left end of the rotating strip plate 5, allowing it to rotate via the fixed shaft. An internally threaded cylinder in the front-to-back direction is located at the right end of the rotating strip plate 5, facilitating the threaded installation of the closing anti-detachment rod 6. A threaded hole extending vertically through the middle of the rotating strip plate 5 allows for the threaded installation of the sealing clamping rod 7. The closing anti-detachment rod 6 is installed inside the internally threaded cylinder of the rotating strip plate 5, preventing the rotated strip plate 5 from tipping over when closed. A threaded rod is located behind the closing anti-detachment rod 6, facilitating its threaded installation. The front end of the threaded rod of the closing anti-detachment rod 6 is... The device features a continuous ring at the top and bottom, facilitating the rotation of the closing anti-detachment rod 6. A sealing clamping rod 7 is installed inside the threaded hole of the flip-up strip plate 5, allowing for easy lifting and lowering via threaded engagement. The outer circumference of the sealing clamping rod 7 is threaded for easy installation. A fixing post is located on the bottom end face of the sealing clamping rod 7, facilitating the installation of a bearing-loaded circular plate 8. A rotating circular plate with anti-slip grooves is located on the top end face of the sealing clamping rod 7, facilitating rotation and anti-slip operation. A bearing-loaded circular plate 8 is installed on the fixing post of the sealing clamping rod 7 via bearings, facilitating contact and force application with the fruit and vegetable preservation cover 4. A bearing groove is located at the center of the top end face of the bearing-loaded circular plate 8, facilitating the installation of the sealing clamping rod 7 via bearings.

[0028] The specific usage and function of this embodiment are as follows:

[0029] In this utility model, such as Figure 1 As shown, the main body 1 of the device is in a closed state. At this time, the internal threaded cylinder of the flipping strip plate 5 is inside the limiting groove on the right side of the fruit and vegetable preservation box 2. The closing anti-dislodgement rod 6 passes through the semi-circular head on the right side of the fruit and vegetable preservation box 2 and screws into the internal threaded cylinder of the flipping strip plate 5, thereby realizing the closing and anti-tipping of the flipping strip plate 5. The insertion strip of the fruit and vegetable preservation cover 4 is inserted into the embedding groove of the fruit and vegetable preservation box 2. The sealing and pressing rod 7 is in a descending state, thereby causing the sealing and pressing rod 7 to apply pressure to the fruit and vegetable preservation cover 4 through the force-bearing circular plate 8. The insert strip of the vegetable preservation lid 4 applies pressure to the sealing airbag strip 3, causing the sealing airbag strip 3 to absorb pressure and expand outward through cavity deformation. The expanded sealing airbag strip 3 forms a four-point sealing contact with the side wall and bottom of the embedding groove of the fruit and vegetable preservation box 2 and the insert strip of the fruit and vegetable preservation lid 4. When the internal air pressure of the fruit and vegetable preservation box 2 changes, the sealing airbag strip 3 adaptively adjusts its deformation through changes in cavity volume, always maintaining contact surface pressure. This overcomes the problem of poor sealing performance caused by the poor deformation ability of traditional solid rubber strips. Figure 1As shown, when the device body 1 is opened, rotating the sealing clamping rod 7 engages with the flipping strip plate 5 via a threaded connection, causing the sealing clamping rod 7 to rise through the threaded engagement. This, in turn, causes the force-bearing circular plate 8 to rise synchronously, thereby releasing the clamping force of the sealing clamping rod 7 on the fruit and vegetable preservation cover 4, as shown in the diagram. Figure 4 As shown, rotating the closing anti-detachment rod 6 engages with the threaded engagement of the flipping strip plate 5, causing the closing anti-detachment rod 6 to move forward through the threaded engagement and disengage from the internal threaded cylinder of the flipping strip plate 5. This releases the closing anti-detachment rod 6 from preventing the flipping of the flipping strip plate 5, resulting in the following state: Figure 5 As shown, then flip the rotating strip 5 upwards by 180 degrees, resulting in the following state. Figure 6 As shown, the fruit and vegetable preservation lid 4 is then lifted upwards to disengage from the embedded groove of the fruit and vegetable preservation box 2, thereby opening the device body 1. This solves the problem that the preservation box and the lid are a press-fit type, which makes the opening process of the lid difficult and easily damages the preservation box and the lid. The reverse operation is the closing operation of the device body 1.

[0030] Example 2: Unlike Example 1, the surface of the flip bar 5 can also be set to a frosted surface, thereby increasing the friction between the surface of the flip bar 5 and the hand, and preventing the surface of the flip bar 5 from slipping when gripping and carrying.

[0031] Example 3: The difference from Example 1 is that the outer circumferential surface of the rotating plate of the sealing clamping rod 7 can also be set as a frosted surface, thereby increasing the friction between the outer circumferential surface of the rotating plate of the sealing clamping rod 7 and the finger, and preventing the sealing clamping rod 7 from slipping when rotating.
