Description

Technical Field

[0001] This utility model relates to the field of laboratory cabinet technology, specifically a laboratory cabinet with a detachable back panel. Background Technology

[0002] Laboratory cabinets are essential equipment in laboratories for storing experimental instruments, reagents, samples, and other items. They offer functions such as categorized storage, safety protection, and efficient management. Laboratory cabinets employ a modular structure, with the back panel connected to the cabinet body via slots and screws. The inside of the back panel typically has pre-installed wiring channels or pipe clamps, allowing for concealed installation of water, electrical, and gas lines. This concealed wiring design reduces exposed wiring and lowers the risk of electric shock or gas leaks.

[0003] In the prior art, such as the laboratory fume hood disclosed in publication number CN220760481U,

[0004] It includes a box body, to which a cabinet is bolted; a door is hinged to the front of the box body; an air filter is bolted inside the door; and a connecting pipe is connected to the back of the cabinet body. This connecting pipe is connected to an exhaust system, which is then activated to exhaust air from the cabinet, creating a negative pressure inside. This negative pressure then draws air out of the box through the connecting pipe, allowing outside air to pass through the air filter before entering the box. This effectively removes harmful gases generated by the stored experimental materials.

[0005] Existing experimental cabinets connect exhaust pipes to an exhaust system, which is then activated to ventilate the interior of the cabinet, creating negative pressure. External air then passes through an air filter before entering the cabinet, effectively removing harmful gases generated by the stored experimental materials. However, most experimental cabinets have a back panel integrated with the frame, making it difficult to inspect and maintain drainage pipes, electrical wiring, and gas lines inside the experimental platform, increasing the difficulty and workload of maintenance.

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.

[0007] Given that most of the existing experimental cabinets have a back panel and frame that are integrated, it is not convenient to inspect and maintain the drainage pipes, electrical circuits and gas pipelines inside the experimental platform, which increases the difficulty and workload of maintenance.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A back panel detachable laboratory cabinet includes a laboratory cabinet body, an installation frame fixed on the upper surface of the laboratory cabinet body, a quick-release mechanism for quick removal of the back panel on the left side of the installation frame, a purification mechanism for air purification on the upper surface of the installation frame, and a protective plate fixed at the upper end inside the installation frame.

[0010] The quick-release mechanism includes a back plate body, which is installed on the left side of the mounting bracket. The inner wall of the back plate body is provided with a connecting groove, and a connecting strip is inserted into the connecting groove.

[0011] As a further improvement of this utility model: a fixing plate is fixed to the side wall of the back plate, and a limiting hole is formed on the upper surface of the fixing plate.

[0012] As a further improvement of this utility model: a limiting rod that is telescopically connected to the experimental cabinet is inserted into the limiting hole, and a spring is sleeved on the outer surface of the limiting rod.

[0013] As a further improvement of this utility model: the end of the spring is connected to a movable block that is fixed to the limiting rod, and two partition boxes are fixed inside the mounting frame.

[0014] As a further improvement of this utility model: the purification mechanism includes a connector, the connector is connected to the upper surface of the mounting frame, and an exhaust device is connected to the right side of the connector.

[0015] As a further improvement of this utility model: a negative pressure fan is fixed inside the exhaust component by bolts, and an ozone generator is fixed to the inner wall of the connector by screws.

[0016] As a further improvement of this utility model: a filter screen is installed horizontally inside the connector, and an activated carbon plate is placed above the filter screen.

[0017] As a further improvement of this utility model: the left side of both the activated carbon plate and the filter screen is fixed with a movable plate that is movably connected to the connector, and the right side of both the activated carbon plate and the filter screen is inserted into a slot opened on the inner wall of the connector.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model uses a negative pressure fan installed inside the exhaust component. When smoke is generated during the user's experiment, the negative pressure fan is activated, and a negative pressure is generated inside the mounting frame through the connecting component, which draws the smoke into the connecting component. When the smoke passes through the filter screen, it can filter dust particles.

[0020] 2. This utility model uses an activated carbon plate to adsorb odors in smoke and an ozone generator to sterilize and disinfect the passing air. The movable plate can be manually pulled out through the slot in the connector, so as to facilitate the replacement of the activated carbon plate and the filter screen.

[0021] 3.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0030] Example 1

[0031] Please see Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides a back panel detachable experimental cabinet, including an experimental cabinet body 1. An installation frame 2 is fixed on the upper surface of the experimental cabinet body 1. A quick-release mechanism for quick removal of the back panel is provided on the left side of the installation frame 2. A purification mechanism for air purification is provided on the upper surface of the installation frame 2. A protective plate 6 is fixed inside the upper end of the installation frame 2.

[0032] The quick-release mechanism includes a back plate 3, which is installed on the left side of the mounting bracket 2. The inner wall of the back plate 3 has a connecting groove 31, and a connecting strip 32 is inserted into the connecting groove 31. Both sides of the connecting strip 32 are fixed with rubber soft strips 33 that are interference fit with the connecting groove 31.

[0033] Specifically, a fixing plate 34 is fixed to the side wall of the back plate 3, and a limit hole 35 is opened on the upper surface of the fixing plate 34.

[0034] Furthermore, the fixing plate 34 can be easily fixed by means of the limiting hole 35 provided on the fixing plate 34.

[0035] Specifically, a limiting rod 36 that is telescopically connected to the experimental cabinet 1 is inserted into the limiting hole 35, and a spring 37 is sleeved on the outer surface of the limiting rod 36.

[0036] Furthermore, manually pulling the limiting rod 36 separates the end of the limiting rod 36 from the limiting hole 35 on the fixed plate 34, and the limiting rod 36 will drive the movable block 38 to compress the spring 37.

[0037] Specifically, the end of the spring 37 is connected to a movable block 38 that is fixed to the limiting rod 36, and two partition boxes 4 are fixed inside the mounting bracket 2.

[0038] Furthermore, the partition box 4 installed inside the mounting frame 2 allows users to easily classify and place items, facilitating experimental operations.

[0039] In use, first place the experimental cabinet 1 in a suitable position. The partition box 4 set in the mounting frame 2 makes it convenient for users to classify and place items, facilitating experimental operations. When it is necessary to disassemble the back panel 3, the limiting rod 36 can be pulled manually to separate the end of the limiting rod 36 from the limiting hole 35 on the fixing plate 34. The limiting rod 36 will drive the movable block 38 to compress the spring 37. At this time, the fixing of the back panel 3 is released. With the cooperation of the connecting strip 32 and the rubber soft strip 33 and the connecting groove 31, the back panel 3 can be easily disassembled, which facilitates the maintenance of the water circuit and electrical circuit in the protective plate 6. When it is necessary to assemble the back panel 3, the disassembly method is reversed to assemble and fix the back panel 3 for easy use.

[0040] In summary, this detachable back panel experimental cabinet allows for easy disassembly of the back panel 3, facilitating maintenance of the water and electrical circuits within the protective panel 6. When reassembling the back panel 3, the disassembly method can be reversed to assemble and fix the back panel 3, making it convenient to use.

[0041] Example 2

[0042] Please see Figures 1-4 This is the second embodiment of the present utility model.

[0043] Specifically, the purification mechanism includes a connector 5, which is connected to the upper surface of the mounting bracket 2, and an exhaust component 51 is connected to the right side of the connector 5.

[0044] Furthermore, the negative pressure fan 52 creates negative pressure within the mounting bracket 2 via the connector 5, drawing smoke into the connector 5.

[0045] Specifically, a negative pressure fan 52 is fixed inside the exhaust component 51 by bolts, an ozone generator 53 is fixed to the inner wall of the connector 5 by screws, a filter screen 54 is installed horizontally inside the connector 5, and an activated carbon plate 55 is placed above the filter screen 54.

[0046] Furthermore, when the smoke passes through the filter 54, it can filter dust particles, while the activated carbon plate 55 can adsorb odors in the smoke.

[0047] Specifically, the left side of both the activated carbon plate 55 and the filter screen 54 is fixed with a movable plate 56 that is movably connected to the connector 5, and the right side of both the activated carbon plate 55 and the filter screen 54 is inserted into a slot 57 opened on the inner wall of the connector 5.

[0048] Furthermore, the movable plate 56 can be manually pulled out by means of the slot 57 opened in the connector 5, thereby removing the activated carbon plate 55 and the filter screen 54.

[0049] In use, the negative pressure fan 52 installed in the exhaust component 51 starts when smoke is generated during the user's experiment. The negative pressure fan 52 creates a negative pressure in the mounting frame 2 through the connector 5, drawing the smoke into the connector 5. When the smoke passes through the filter screen 54, it can filter dust particles, while the activated carbon plate 55 can adsorb odors in the smoke. The ozone generator 53 converts oxygen O2 into ozone O3. Based on corona discharge, ultraviolet irradiation, or water electrolysis, oxygen molecules are decomposed into oxygen atoms. Then, the oxygen atoms combine with oxygen molecules to generate ozone, which sterilizes and disinfects the air. The ozone is then discharged to the outside through the exhaust component 51. The movable plate 56 can be manually pulled through the slot 57 in the connector 5 to remove the activated carbon plate 55 and the filter screen 54 for easy replacement. The protective plate 6 installed in the mounting frame 2 can protect water pipes, cables, etc.

[0050] In summary, this detachable back panel experimental cabinet allows for easy disassembly of the back panel 3 during use, facilitating maintenance of the water and electrical circuits within the protective panel 6. When reassembling the back panel 3, the disassembly method is reversed for easy assembly and fixation. Furthermore, the negative pressure fan 52 within the exhaust component 51 creates negative pressure within the mounting frame 2 via the connector 5, drawing smoke into the connector 5. As the smoke passes through the filter screen 54, dust particles are filtered out, while the activated carbon plate 55 adsorbs odors from the smoke. Finally, the ozone generator 53 sterilizes and disinfects the passing air.
