Description

Technical Field

[0001] This utility model relates to the field of delivery box technology, and more specifically, to a cold chain delivery box. Background Technology

[0002] Delivery boxes, frequently used in the vegetable delivery industry, facilitate the bulk delivery and handling of vegetables. Cold chain delivery boxes, in particular, can maintain the freshness of vegetables by using cold air while delivering them.

[0003] To meet customer demand, the vegetable delivery industry has changed its delivery model. When faced with small-batch, multi-variety orders (such as community households and small catering businesses requiring different types of vegetables, but with small order quantities for each type), mixed packaging is usually adopted to improve delivery efficiency and reduce transportation costs. This involves placing different vegetables in the same delivery box to integrate resources and reduce repeated transportation.

[0004] Publication number CN221802167U discloses a portable self-regulating constant temperature box. Its technical solution includes a box body and a temperature control box. The temperature control box is fixed outside the box body. Inside the temperature control box are a semiconductor refrigeration module, a temperature monitoring module, and a power supply. The semiconductor refrigeration module includes a cooling chip, a cold-end heat conduction head, and a hot-end heat conduction head. The coolant circulation system includes a cold-end heat exchanger and a first pump body. The cold-end heat exchanger is located inside the box body and forms an active convection radiator with the cold-end heat conduction head and the first pump body inside the temperature control box through a first connecting valve and a second connecting valve, enabling rapid convection cooling. The hot-end radiator inside the temperature control box forms an active cooling water radiator with the second pump body and the hot-end heat conduction head. Convection magnetic levitation fans are provided on the heat dissipation or heat exchange end faces of both the hot-end radiator and the cold-end heat exchanger.

[0005] The above technical solution, through the setting of the semiconductor cooling module, can reduce the temperature inside the box, and at the same time, through the setting of the coolant circulation system, can slow down the loss of temperature inside the box, thereby extending the cold chain delivery endurance.

[0006] However, when different types of vegetables need to be placed in the same delivery box for delivery, the required cold chain temperature will also be different due to the different types of vegetables. For example, tomatoes require a cold chain temperature of 10℃ to 13℃, while cabbage requires a cold chain temperature of 0℃ to 2℃. The above technical solution can only keep the inside of the box at the same temperature and cannot carry out cold chain transportation of different types of vegetables at the same time. Therefore, a new solution is needed to solve this problem. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] A type of cold chain delivery box, such as Figures 1-3 As shown, the device includes a housing 2 with a refrigeration unit 1 and a cover 3 connected to the housing 2. The housing 2 has a first chamber 4 and a second chamber 5. The refrigeration unit 1 is located on the side of the housing 2 near the second chamber 5. An insulation plate 6 is fixedly connected between the first chamber 4 and the second chamber 5. Insulation layers 26 are fixedly connected to both sides of the insulation plate 6. The insulation layers 26 can be made of polyurethane insulation material, which can effectively improve the temperature insulation effect of the insulation plate 6. The insulation plate 6 has a vent 7 for air to communicate between the first chamber 4 and the second chamber 5. A groove 8 is provided at the bottom of the vent 7. A baffle 9 for controlling the opening and closing of the vent 7 is slidably connected to the side wall of the groove 8, and an electric push rod 10 is fixedly connected to the bottom. The output end of the electric push rod 10 is fixedly connected to the baffle 9.

[0022] When using the delivery box to deliver different types of vegetables, rotate the cover 3 to open the box 2. Then, place the vegetables requiring higher cold chain temperatures into chamber 1 (4) and those requiring lower cold chain temperatures into chamber 2 (5). Close the cover 3 to close the box 2. Then, activate the electric push rod 10. The output of the electric push rod 10 drives the baffle 9 downwards, causing it to enter the slide groove 8 and separate from the vent. At this time, the vent is open, allowing chamber 1 (4) and chamber 2 (5) to communicate. Then, start the refrigeration unit 1, which delivers cold air to chamber 2 (5). Simultaneously, cold air enters chamber 1 (4) through the vent 7. When the temperature in chamber 1 (4) reaches the required cold chain temperature for the vegetables, activate the electric push rod 10 again. The baffle 9 is moved upward, bringing it into contact with the top of the vent 7 and closing it. At this point, chamber 1 (4) and chamber 2 (5) cannot communicate with each other. The refrigeration unit 1 then continues to deliver cold air into chamber 2 (5). The cold air is restricted by the baffle 9 and cannot enter chamber 1 (4), thus achieving a temperature in chamber 2 (5) that is lower than that in chamber 1 (4). When the temperature in chamber 2 (5) reaches the temperature required for the cold chain of vegetables, the refrigeration unit 1 stops working. This achieves the effect of simultaneously transporting different types of vegetables in the cold chain. By setting up the partition plate 6 and the baffle 9, the temperature in chamber 1 (4) and chamber 2 (5) can be adjusted independently, facilitating the cold chain distribution of different types of vegetables and improving the practicality of the cold chain distribution box.

[0023] Furthermore, a sealing block 11 is fixedly connected to the top of the baffle 9, and a sealing groove 12 is provided on the top of the vent 7 for the sealing block 11 to be inserted. A sealing strip 13 is fixedly connected in the sealing groove 12. Both the sealing block 11 and the sealing strip 13 can be made of rubber, which can drive the baffle 9 to move upward, thereby moving the sealing block 11 in the same direction and inserting the sealing block 11 into the sealing groove 12, where it comes into contact with the sealing strip 13. By using the sealing block 11 and the sealing strip 13, the sealing effect between the baffle 9 and the vent 7 can be further improved after the vent 7 is closed.

[0024] Furthermore, motors 14 are fixedly connected to both chamber 4 and chamber 5. These motors 14 are waterproof. The water generated during the cold chain distribution of vegetables is prevented from causing short circuits when the motor 14 comes into contact with water, thus extending its service life. The output end of the motor 14 is fixedly connected to an upward-facing fan blade 15. When the cold air is stationary, it sinks. The motor 14 drives the fan blade 15 to rotate, blowing the sinking cold air upward. This makes the cold air distribution in chambers 4 and 5 more even. The inner walls of chambers 4 and 5 are fitted with a retaining net 16 to prevent the vegetables from contacting the fan blade 15 and thus avoid affecting its normal operation. The through holes in the retaining net 16 also prevent interference with the normal operation of the fan blade 15.

[0025] Furthermore, a thermometer 17 is fixedly connected to the bottom of the limiting net 16. Placing the thermometer 17 at the bottom of the limiting net 16 can prevent the thermometer 17 from bumping into the vegetables and improve the service life of the thermometer 17. The side wall of the box body 2 is equipped with a display screen 18, which can monitor the temperature in the first chamber 4 and the second chamber 5 at any time, making it easier to adjust the temperature in the first chamber 4 and the second chamber 5 in a timely manner.

[0026] like Figure 2 , Figure 3 As shown, a connecting frame 19 is slidably connected within chamber 1 (4) and chamber 2 (5). A breathable mesh 20 is fixedly connected within the connecting frame 19. Grooves 21 are provided on both sides of the connecting frame 19, and mounting plates 22 are slidably connected within the grooves 21. Several mounting slots 23 for the mounting plates 22 to enter are provided inside the housing 2 and on both sides of the partition plate 6. A moving rod 24 is slidably connected to the connecting frame 19. The moving rod 24 passes through the connecting frame 19 into the groove 21 and is fixedly connected to the side wall of the mounting plate 22. The moving rod 24 is away from the mounting plate. A lever 25 is fixedly connected to one side of 22, which facilitates the movement of the moving rod 24. When stacking vegetables, the connecting frame 19 is placed in the first chamber 4 and the second chamber 5. Then, the lever 25 is pushed to move the moving rod 24 and drive the mounting plate 22 into the mounting groove 23. Then, the vegetables are placed on the breathable net 20. With the connection frame 19 and the limiting net 16, the vegetables at the bottom are prevented from being squeezed, thus improving the protection of the vegetables.

[0027] The usage process of this utility model is as follows: When using the delivery box to deliver different types of vegetables, rotate the cover 3 to open the box 2. Then, place the vegetables requiring higher temperatures for the cold chain into chamber 1 4 and the vegetables requiring lower temperatures into chamber 2 5. Close the cover 3 to close the box 2. Then, activate the electric push rod 10. The output end of the electric push rod 10 drives the baffle 9 downwards, causing the baffle 9 to enter the slide 8 and separate from the vent. At this time, the vent is open, allowing chamber 1 4 and chamber 2 5 to communicate. Then, start the refrigeration unit 1, which delivers cold air to chamber 2 5. Simultaneously, cold air enters chamber 1 4 through the vent 7. When chamber 1 4... When the temperature inside reaches the required cold chain temperature for the vegetables in chamber 4, the electric push rod 10 is activated again to drive the baffle 9 upward, bringing the baffle 9 and the top of the vent 7 into contact and closing the vent 7. At this time, chamber 4 and chamber 5 cannot communicate with each other. Then, the refrigeration unit 1 continues to be driven to deliver cold air into chamber 5. At this time, the cold air is restricted by the baffle 9 and cannot enter chamber 4, thus achieving the effect that the temperature inside chamber 5 is lower than that inside chamber 4. When the temperature inside chamber 5 reaches the required cold chain temperature for the vegetables in chamber 5, the refrigeration unit 1 is driven to stop working, thereby achieving the effect of simultaneously carrying out cold chain transportation of different types of vegetables.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
