Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, and in particular to a chemical material cooling device. Background Technology

[0002] In chemical experiments and production processes, the storage of chemical materials is subject to strict temperature requirements. Therefore, cooling devices are crucial equipment for ensuring the stability and safety of chemical materials. Currently, most common chemical material cooling devices on the market take the form of freezers.

[0003] However, in practical use, it has been found that existing freezers have many drawbacks when frequently accessing and removing chemical materials. Firstly, each time the freezer door is opened, the low-temperature environment inside is disrupted. The influx of hot outside air causes a rapid rise in temperature, affecting not only the storage conditions of the chemical being accessed but also the stability of other chemicals inside the freezer. This can even lead to some chemicals deteriorating or becoming ineffective due to temperature fluctuations, affecting experimental results or production quality. Secondly, frequent opening of the freezer door results in a significant loss of cold air. To maintain a stable low-temperature environment inside the freezer, the cooling system needs to consume more energy to recool, which undoubtedly increases energy consumption and operating costs, and is inconsistent with the trend of energy conservation and environmental protection.

[0004] Therefore, there is a need for a chemical material cooling device that can effectively reduce the impact of frequent handling of chemical materials on other chemical materials and reduce energy loss caused by cold air leakage. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems of the aforementioned chemical material cooling device, this utility model is proposed.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a chemical material cooling device, including a freezer, the interior of which is divided into a lower refrigeration zone and multiple independent upper refrigeration zones by partitions;

[0008] Several connecting rings are provided on the partition to connect the independent upper and lower sections. The connecting rings are provided with multiple vents at equal intervals along the circumference. The top of the connecting rings is connected to a cooling cover that extends to the outside of the freezer for placing the storage tank.

[0009] The air guiding assembly includes:

[0010] A fixed plate is located on the inner wall of the connecting ring, and its outer edge forms several gaps with the inner wall of the connecting ring.

[0011] A sliding shaft is slidably mounted on a fixed plate, with its top end extending into the cooling shroud and elastically connected to the fixed plate by a spring. The sliding shaft is also axially slid along the connecting ring under the pressure of the placement tank.

[0012] The moving ring, located at the bottom of the sliding shaft, normally fits against the fixed plate and seals the gap under the control of the spring force, and the airflow in the lower zone is conducted to the outside of the cooling shroud through the vent. When the container is placed inside the cooling shroud, the sliding shaft is pressed down and the moving ring moves away from the fixed plate and seals the vent, and the airflow in the lower zone is conducted to the inside of the cooling shroud.

[0013] In a preferred embodiment of the chemical material cooling device of this utility model, the axial direction of the sliding shaft is the same as the insertion direction of the placement tank.

[0014] In a preferred embodiment of the chemical material cooling device of this utility model, the outer layer of the moving ring is a rubber layer, and the rubber layer is bonded to the inner wall of the connecting ring.

[0015] In a preferred embodiment of the chemical material cooling device of this utility model, the axial length of the moving ring is greater than the opening width of the vent.

[0016] As a preferred embodiment of the chemical material cooling device of this utility model, the placement tank includes a tank body, a threaded tank cover, and an inner sleeve fixed to the bottom wall of the tank body.

[0017] In a preferred embodiment of the chemical material cooling device of this utility model, the top end of the sliding shaft is provided with an extension plate extending in all directions, and the radial dimension of the extension plate is larger than the opening diameter of the inner sleeve.

[0018] The beneficial effects of this invention are as follows: The shelves within the freezer divide it into multiple independent refrigerated zones. This zoned design not only facilitates the categorized storage of chemical materials with different properties but also effectively prevents temperature fluctuations caused by frequent door openings during retrieval, avoiding interference from external hot air on chemical materials in other areas and greatly ensuring the stability of the storage environment. The air guiding component dynamically adjusts the cold air flow path based on whether a storage container is placed inside the cooling hood: when the cooling hood is empty, the component directs cold air to the outside for pre-cooling, ensuring the storage container quickly reaches the preset temperature upon placement; when a storage container is inside, the cold air is directly directed to the inside for targeted cooling of the chemical materials within. This airflow method significantly improves cooling efficiency and avoids ineffective cold air loss, ensuring rapid cooling of chemical materials while effectively reducing the overall energy consumption of the device.

[0029] Reference Figures 1-4 This invention provides a chemical material cooling device, which includes a freezer 1. The interior is divided into a lower refrigeration zone and multiple independent upper refrigeration zones by a partition 11. The partition 11 consists of a horizontal plate and several vertical plates. The partitioned storage can avoid interference between different chemical materials. Especially when chemical materials are frequently taken out and put in, the independent upper refrigeration zones can prevent the outside hot air introduced by opening the cabinet door from affecting the chemical materials in other areas, ensuring the stability of the storage environment of chemical materials in each area and reducing the risk of chemical materials deteriorating or becoming ineffective due to temperature fluctuations.

[0030] Several connecting rings 2 are provided on the partition 11 to connect the independent upper and lower zones. The connecting rings 2 have multiple vents 21 equidistantly spaced along the circumference. The connecting rings 2 and the vents 21 form a cold air circulation path, so that the cold air in the lower refrigeration zone can be transferred to the upper refrigeration zone. The top of the connecting rings 2 is connected to a cooling cover 22 extending outside the freezer 1 for placing the storage can 4. The cooling cover 22 eliminates the need to frequently open the cabinet door when taking out or placing the storage can 4, reducing the loss of cold air in the freezer 1 and reducing energy consumption.

[0031] The placement container 4 includes a container body 41, a threaded container cover 42, and an inner sleeve 43 fixed to the bottom wall of the container body 41. The container body 41 can be connected to the inner wall of the cooling cover 22 by a threaded connection. The sealed placement container 4 can effectively protect the chemical materials and maintain the stability of their storage state. The inner sleeve 43 can increase the contact area between the cold air and the container body 41, and further improve the cooling efficiency.

[0032] Air guiding assembly 3 includes:

[0033] The fixed plate 31 is located on the inner wall of the connecting ring 2, and its outer edge forms several gaps with the inner wall of the connecting ring 2, which serve as the initial channel for the flow of cold air.

[0034] A sliding shaft 32 is slidably mounted on a fixed plate 31, with its axial direction aligned with the insertion direction of the placement tank 4. Its top end extends into the cooling cover 22 and is elastically connected to the fixed plate 31 via a spring 34, which provides elastic restoring force to the sliding shaft 32. The top end of the sliding shaft 32 is rotatably provided with an extension plate extending outwards, the radial dimension of which is larger than the opening diameter of the inner sleeve 43, used to bear the pressure of the placement tank 4. Furthermore, the sliding shaft 32 slides axially along the connecting ring 2 under the pressure of the placement tank 4.

[0035] The moving ring 33 is located at the bottom end of the sliding shaft 32. The axial length of the moving ring 33 is greater than the opening width of the vent 21. The outer layer of the moving ring 33 is a rubber layer, and it is attached to the inner wall of the connecting ring 2 through the rubber layer.

[0036] Under normal conditions, spring 34 causes sliding shaft 32 to drive moving ring 33 to fit against fixed plate 31, sealing the gap. Cold air is guided through vent 21 to the outside of cooling cover 22 for pre-cooling, facilitating rapid cooling of the placement tank 4 after it is placed inside. When the placement tank 4 is inside cooling cover 22, sliding shaft 32 is pressed down, moving ring 33 closes vent 21, and cold air is directly guided into cooling cover 22 to cool the placement tank 4. This method of switching the cold air flow path improves cooling efficiency, avoids ineffective cold air loss, and reduces the overall energy consumption of the device.

[0037] In addition, after the container 4 is removed from the cooling cover 22, the top opening of the cooling cover 22 can be sealed with a sealing cap (not shown in the text) to prevent the loss of cold air.

[0038] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
