Description

Technical Field

[0001] This utility model relates to the field of reagent cabinet technology, specifically to an intelligent air purification reagent cabinet. Background Technology

[0002] In laboratories, medical testing institutions, and research institutes, reagent storage must meet the requirements of a clean and safe environment. As a core storage device, the intelligent air purification reagent cabinet removes volatile harmful gases in the cabinet through a built-in air purification system (such as activated carbon filtration and HEPA high-efficiency filtration). At the same time, it is equipped with temperature and humidity monitoring, intelligent alarm and other functions to provide a stable and reliable environment for reagent storage. It has been widely used in the daily management of various sensitive reagents such as chemical reagents and biological reagents.

[0003] In the structural design of existing intelligent air-purifying reagent cabinets, multiple layers of trays are typically installed inside the cabinet to hold reagent bottles or containers of different sizes and types, enabling classified storage and convenient retrieval of reagents. However, the connection between the trays and the cabinet body in current intelligent air-purifying reagent cabinets is mostly a fixed installation structure. Specifically, the cabinet side wall has pre-set fixing slots or bolt holes, and the trays are connected to the cabinet body by snap-fitting or bolt fastening. Once installed, the height of the trays cannot be adjusted according to actual usage needs. This fixed-height tray design has obvious limitations. On the one hand, the packaging specifications of different types of reagents vary greatly. For example, some large reagent bottles are tall, while regular reagent bottles are short. When it is necessary to store reagents whose height exceeds the fixed tray spacing, the reagents cannot be placed smoothly into the cabinet.

[0004] In view of this, the present invention proposes an intelligent air purification reagent cabinet to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent air-purifying reagent cabinet, which allows for flexible adjustment of the height of the placement tray through the cooperation of the placement tray and the height adjustment mechanism.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an intelligent air purification reagent cabinet, including a cabinet body, an air purification mechanism installed inside the cabinet body, and a tray for holding reagents;

[0007] The cabinet's inner cavity is fitted with an installation frame, and multiple guide rails are fixedly connected to the opposite sides inside the installation frame.

[0008] Each guide rail has a sliding groove on one side and a connecting plate on one side. A connecting shaft slides through the inner cavity of the connecting plate. One end of the connecting shaft extends into the sliding groove and is fixedly connected to a sliding block. A return spring is provided between the sliding block and the connecting plate. A pin rotates through the inner cavity of the connecting shaft. Both ends of the pin extend out of the connecting shaft and are fixedly connected to an eccentric wheel. A lever for driving the eccentric wheel to rotate is fixedly connected to the outer circumferential surface of the eccentric wheel.

[0009] The sliding block has symmetrically opened limiting grooves on one side facing the connecting plate. Several limiting blocks that are adapted to the limiting grooves are fixedly connected to the inner wall of the sliding grooves. The limiting blocks are distributed along the length direction of the sliding grooves.

[0010] Furthermore, the cross-sections of the sliding groove and the sliding block are both T-shaped, the cross-sections of the limiting groove and the limiting block are both triangular, and the bottom of the placement plate is fixedly connected to the top of the connecting plate.

[0011] Furthermore, the inner cavity of the cabinet is slidably connected to sliding cabinet a and sliding cabinet b via slide rails, and the surfaces of sliding cabinet a and sliding cabinet b are provided with sliding grooves to facilitate the application of force.

[0012] Furthermore, the bottom of the mounting frame is provided with multiple ventilation holes a, which are connected to the internal space of the sliding cabinet a, and the top of the mounting frame is provided with multiple ventilation holes b, which are connected to the airflow channel of the air purification mechanism.

[0013] Furthermore, the cabinet's inner cavity is rotatably connected to an opening and closing door a, an opening and closing door b, and a control panel. The opening and closing door a, the opening and closing door b, and the control panel are symmetrically arranged along the cabinet's symmetry plane, and the height of the opening and closing door b is less than the height of the opening and closing door a.

[0014] Furthermore, the cabinet body and the closed contact surfaces of the opening and closing doors a, b, and the control panel are all fixedly connected with electromagnets to enhance the sealing performance.

[0015] Furthermore, the return spring is sleeved on the outside of the connecting shaft, and one end of the return spring is fixedly connected to one side of the sliding block.

[0016] Furthermore, the outer peripheral surface of the eccentric wheel is coated with an anti-slip layer, which covers the area where the eccentric wheel contacts the inner wall of the connecting plate.

[0017] In summary, this utility model has the following beneficial effects:

[0018] To address the problem in existing technologies where the placement tray and cabinet are fixed in place (e.g., with pre-set slots and bolts), resulting in no height adjustment and thus preventing the placement of large reagent bottles while wasting space for regular reagent bottles, this reagent cabinet utilizes a combination of placement tray and height adjustment mechanism to achieve flexible height adjustment of the placement tray. Operators simply need to move a lever, which drives the connecting shaft via an eccentric wheel, disengaging the sliding block from the limiting block in the sliding groove. This moves the placement tray along the sliding groove on the guide rail to the target height. Moving the lever in the opposite direction re-engages the limiting groove and the limiting block. This adjustment method eliminates the need to remove bolts or adjust the fixed slots, allowing for flexible adaptation to the height requirements of different reagent sizes. It avoids the problem of large reagent bottles being unable to fit due to insufficient tray spacing and allows for adjustment of shelf spacing for regular reagent bottles, preventing wasted vertical space within the cabinet and significantly improving the storage adaptability of the reagent cabinet.

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] like Figure 1-7 As shown, an intelligent air-purifying reagent cabinet includes a cabinet body 1, an air purification mechanism 101 installed inside the cabinet body 1, and a tray 102 for holding reagents.

[0029] The inner cavity of the cabinet 1 is fitted with an installation frame 2, and multiple guide rails 201 are fixedly connected to the opposite sides inside the installation frame 2.

[0030] Each guide rail 201 has a sliding groove 202 on one side and a connecting plate 203 on one side. A connecting shaft 204 slides through the inner cavity of the connecting plate 203. One end of the connecting shaft 204 extends into the interior of the sliding groove 202 and is fixedly connected to a sliding block 205. A return spring 206 is provided between the sliding block 205 and the connecting plate 203. A pin is rotatably passed through the inner cavity of the connecting shaft 204. Both ends of the pin extend out of the connecting shaft 204 and are fixedly connected to an eccentric wheel 207. A lever 208 for driving the eccentric wheel 207 to rotate is fixedly connected to the outer circumferential surface of the eccentric wheel 207.

[0031] The sliding block 205 has symmetrically opened limiting grooves 209 on one side facing the connecting plate 203. The inner wall of the sliding groove 202 is fixedly connected with several limiting blocks 210 that are adapted to the limiting grooves 209. The limiting blocks 210 are distributed along the length direction of the sliding groove 202.

[0032] The sliding groove 202 and the sliding block 205 both have a T-shaped cross-section, the limiting groove 209 and the limiting block 210 both have a triangular cross-section, and the bottom of the placement plate 102 is fixedly connected to the top of the connecting plate 203.

[0033] The inner cavity of cabinet 1 is slidably connected to sliding cabinet a3 and sliding cabinet b301 via slide rails. The surfaces of sliding cabinet a3 and sliding cabinet b301 are provided with sliding grooves 302 to facilitate the application of force.

[0034] The bottom of the mounting frame 2 has multiple ventilation holes a4 that are connected to the internal space of the sliding cabinet a3. The top of the mounting frame 2 has multiple ventilation holes b401 that are connected to the airflow channel of the air purification mechanism 101.

[0035] The inner cavity of the cabinet 1 is rotatably connected to the opening and closing door a5, the opening and closing door b501 and the control panel 502. The opening and closing door a5, the opening and closing door b501 and the control panel 502 are symmetrically arranged along the symmetry plane of the cabinet 1, and the height of the opening and closing door b501 is less than the height of the opening and closing door a5.

[0036] The cabinet body 1 is fixedly connected to the closing surfaces of the hinged doors a5, b501, and control panel 502 with electromagnets 6 for enhancing sealing.

[0037] The return spring 206 is sleeved on the outside of the connecting shaft 204, and one end of the return spring 206 is fixedly connected to one side of the sliding block 205.

[0038] The outer peripheral surface of the eccentric wheel 207 is coated with an anti-slip layer, which covers the area where the eccentric wheel 207 contacts the inner wall of the connecting plate 203.

[0039] The basic working principle of this utility model is as follows: When it is necessary to adjust the height of the placement plate 102, the operator moves the dial 208, which drives the eccentric wheel 207 to rotate around the pin shaft (the pin shaft passes through the inner cavity of the connecting shaft 204 and is fixed at both ends to the eccentric wheel 207); as the eccentric wheel 207 rotates, its eccentric structure pushes the connecting shaft 204 to slide along the inner cavity of the connecting plate 203, causing the sliding block 205 at one end of the connecting shaft 204 to move away from the connecting plate 203. At this time, the return spring 206 between the sliding block 205 and the connecting plate 203 extends, and at the same time, the limiting groove 209 on the sliding block 205 disengages from the limiting block 210 on the inner wall of the sliding groove 202 (the limiting block 210 is distributed along the length of the sliding groove 202 and is used to fix the position of the sliding block 205).

[0040] After the limiting groove 209 disengages from the limiting block 210, the sliding block 205 can slide freely up and down along the sliding groove 202 on the guide rail 201, driving the connecting plate 203 and the placement tray 102 fixed to the top of the connecting plate 203 to move synchronously. According to the reagent storage requirements, the operator adjusts the placement tray 102 to the target height. During this period, the T-shaped cross-sectional structure of the sliding groove 202 and the sliding block 205 can prevent the sliding block 205 from falling out of the sliding groove 202, ensuring sliding stability.

[0041] After adjusting to the target height, the lever 208 is moved in the opposite direction, the return spring 206 is compressed, and the connecting shaft 204 and the sliding block 205 are pushed to return to the direction close to the connecting plate 203 until the limiting groove 209 on the sliding block 205 and the limiting block 210 at the corresponding position on the inner wall of the sliding groove 202 are re-engaged (the limiting groove 209 and the limiting block 210 have a triangular cross-sectional structure), thereby fixing the position of the sliding block 205 and thus completing the height locking of the placement plate 102;

[0042] Sliding cabinets a3 and b301 are slidably connected to the inner cavity of cabinet 1 via slide rails. Operators can pull sliding cabinet a3 or b301 through sliding groove 302 to store reagents that do not require purification. At the same time, ventilation hole a4 at the bottom of mounting frame 2 is connected to the internal space of sliding cabinet a3, and ventilation hole b401 at the top of mounting frame 2 is connected to the airflow channel of air purification mechanism 101. When air purification mechanism 101 is working, it can draw air from sliding cabinet a3 through ventilation hole a4, purify it, and then return it through ventilation hole b401 to achieve air circulation purification in sliding cabinet a3.

[0043] Doors a5 and b501 are connected to the inner cavity of cabinet 1 via a rotating structure and are symmetrically arranged along the symmetry plane of cabinet 1. Operators can open doors a5 or b501 to retrieve reagents from inside cabinet 1 and control the operation of components such as air purification mechanism 101 and electromagnet 6 through control panel 502. Electromagnets 6 are fixed to the closed contact surfaces of cabinet 1, doors a5 and b501, and control panel 502. When doors a5, b501, or control panel 502 are closed, electromagnets 6 are energized to generate magnetic attraction, enhancing the sealing of the closed area and preventing the leakage of harmful gases inside cabinet 1.

[0044] The outer peripheral surface of the eccentric wheel 207 is coated with an anti-slip layer, and the anti-slip layer covers the area in contact between the eccentric wheel 207 and the inner wall of the connecting plate 203. During the process of the eccentric wheel 207 pushing the connecting shaft 204 to slide, the anti-slip layer can increase the friction coefficient between the eccentric wheel 207 and the inner wall of the connecting plate 203, prevent the eccentric wheel 207 from slipping when rotating, and ensure the sliding drive stability of the connecting shaft 204.

[0045] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
