Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration equipment for cold chain logistics, and specifically, to refrigeration equipment for a cold chain system of smart logistics services. Background Art

[0002] Cold chain logistics is a logistics activity based on freezing technology, refrigeration technology and cold storage technology, which ensures that cold chain items are always kept in a specified temperature environment in each link from production, circulation, sales to consumers, so as to ensure the quality of cold chain items and reduce the loss of cold chain items. The working field of cold chain logistics is wide, involving industries such as food and medicine. With the continuous improvement of people's requirements for the safety of food, medicine, etc., the performance and functions of refrigeration equipment in cold chain logistics need to be improved to ensure the quality of cold chain items.

[0003] The applicant has found through searching that the functions of freezers commonly used in the existing cold chain logistics refrigeration equipment are relatively simple and can only perform single freezing storage. When transporting fruit and vegetable items for a long time, the humidity of such items cannot be guaranteed, and the possibility of wilting and deterioration increases. When transporting biological products and medicines, such items need to avoid excessive humidity that causes the items to become damp and deteriorate. If the freezer cannot humidify and dehumidify the existing items, the damage rate of the items will be greatly increased, which is not conducive to the development of cold chain logistics and reduces the transportation efficiency of cold chain logistics. Therefore, the inventor particularly needs to design a refrigeration equipment for a smart logistics service cold chain system to solve the above technical problems. Summary of the invention

[0004] The purpose of the present invention is to provide a refrigeration device for a smart logistics service cold chain system to solve the problems raised in the above-mentioned background technology.

The humidifying main board has its other end installed inside the protective box through a bearing seat. The humidifying plate is sleeved on the reciprocating screw and rotatably connected to the reciprocating screw. The side of the humidifying plate is installed on the limiting slide rod through a slider. Humidifying nozzles are evenly distributed in the groove on the front of the humidifying plate. The dehumidification structure includes a dehumidifying main board, a dehumidifier and a double-threaded screw. With the double-threaded screw as the center, the dehumidifier is symmetrically arranged inside the dehumidifying main board. The dehumidifier is installed on the inner wall of the dehumidifying main board through a dehumidifying mounting plate. The wide-pitch threads at one end of the double-threaded screw are evenly distributed from top to bottom to the smooth part of the rod body, and the dense threads at the other end of the double-threaded screw are evenly distributed from bottom to top to the smooth part of the rod body. Preferably, a window is provided on the front side of the dehumidification main board, and a protective shift plate and a linkage rod are respectively provided on the double-threaded screw rod, and the protective shift plate is adapted to the window of the dehumidification main board.

[0006] Preferably, a water pump is provided on the side of the rotating motor, and a water pumping pipe of the water pump extends into the moisture collecting main chamber. A water pumping head is installed at the protruding end of the water pumping pipe, and a water supply pipe is installed on the side of the water pump. One end of the supply hose is connected to the humidification plate, and the other end passes through the humidification frame and is connected to the water supply pipe through a connector.

[0007] Preferably, the main current collecting bin is provided with a number of through holes, and an isolation plate is arranged below the corresponding through holes. One end of the linkage rod extends into the main current collecting bin and is fixedly connected to the isolation plate, and the other end of the linkage rod is sleeved on the double-threaded screw and rotatably connected to the double-threaded screw.

[0008] Preferably, a rotating motor is arranged on the side of the protective box, the motor shaft of the rotating motor passes through the protective box and a motor gear is installed on the motor shaft head, the shaft of the reciprocating screw extending into the protective box is installed with a screw gear, and the screw gear and the motor gear are meshed with each other.

[0009] Preferably, a protective seat is provided below the dehumidifier, a partition plate is installed at the bottom of the protective seat, and the partition plate surrounds the double-threaded screw rod.

[0010] Preferably, a partition bottom plate is provided below the protective seat, and the partition bottom plate is installed at the bottom opening of the dehumidification main board. The densely threaded ends of the double-threaded screw rod pass through the protective seat and the partition bottom plate in sequence and are connected to the bottom plate motor below the dehumidification main board.

[0012] Preferably, a refrigerator flap is installed on the top of the refrigerator body, and a liquid control screen and an exhaust grille are installed on the front and side of the refrigerator body respectively.

[0013] The beneficial effects of the present invention are: 1. By setting up a mobile humidification structure, the humidification nozzles on the humidification plate can spray water mist to humidify items in different areas from different heights, which can effectively increase the humidity in the refrigerator and help the goods retain moisture, thereby extending the shelf life and improving product quality. The dehumidifier in the dehumidification structure extracts excess moisture inside the refrigerator and discharges it into the main moisture collection bin required for humidification through the dehumidification pipe. It can effectively control the humidity in the refrigerator and prevent items from being damp and deteriorating due to excessive moisture, effectively extending the service life of items in the refrigerator, and ensuring that the items are always in a suitable humidity environment.

[0014] 2. The isolation plate set in the moisture collection main bin can be linked with the protective shift plate through a linkage rod. Due to the different pitches set at both ends of the double-threaded screw, the isolation plate and the protective shift plate move different distances when the double-threaded screw rotates. The row spacing of the protective shift plate is much larger than that of the isolation plate, ensuring that the protective shift plate and the isolation plate are opened to the optimal position at the same time before the dehumidification structure starts working.

[0015] 3. When the dehumidification structure is working, the moisture collection main bin can collect water droplets that move freely downward on the items, thereby increasing the dehumidification effect of the refrigerator and facilitating the dehumidification work of the refrigerator. It can be used as both a humidification supply bin and a dehumidification collection bin, which is very convenient. BRIEF DESCRIPTION OF THE DRAWINGS
