[0022] This application discloses a laminar flow clean cabinet.

[0023] Reference Figure 1 , Figure 3 and Figure 4A laminar flow clean cabinet includes a cabinet body 1, an exhaust vent 3 on the top of the cabinet body 1, a partition 4 fixedly connected to the inner wall of the cabinet body 1, a fixed laminar flow shelf 5 fixedly connected to the side wall of the partition 4, and a movable laminar flow shelf 9 for gas flow and transportation detachably connected to the side wall of the partition 4. Both the fixed laminar flow shelf 5 and the movable laminar flow shelf 9 have flow holes 29 on their surfaces.

[0024] Reference Figure 1 and Figure 2 An electrical control box 2 is installed on the top of the cabinet 1. A first sliding door 6 is rotatably connected to the outer wall of the cabinet 1, and a second sliding door 7 is rotatably connected to the outer wall of the cabinet 1. The first sliding door 6 is located on one side of the movable laminar flow shelf 9, so as to achieve the effect of convenient pull-out and disassembly of the movable laminar flow shelf 9.

[0025] Reference Figure 4 A connecting box 14 is fixedly connected to the inner wall of the cabinet 1. A locking block 16 is slidably connected to the inner wall of the connecting box 14. A plug rod 15 for locking the locking block 16 is fixedly connected to the outer wall of the movable laminar flow shelf 9. A spring 18 is fixedly connected to the side wall of the cabinet 1. A sliding rod 17 for driving the locking block 16 to extend and retract along the side wall of the cabinet 1 is slidably connected to the side wall of the cabinet 1. The outer wall contour of the initial contact part between the locking block 16 and the plug rod 15 is inclined, and the outer wall contour of the locking part between the locking block 16 and the plug rod 15 is flat. Through the locking connection between the locking block 16 and the plug rod 15, the movable laminar flow shelf 9 can be detachably connected and used inside the cabinet 1.

[0026] Reference Figure 4 One end of the spring 18 is fixedly connected to a connecting block 19 for driving the sliding rod 17 to extend and retract. The connecting block 19 is fixedly connected to one end of the sliding rod 17. A miniature electric push rod 20 is provided on the side wall of the cabinet 1, located on one side of the connecting block 19. A slide rail is fixedly connected to the side wall of the partition 4 and slidably connected to the side wall of the movable laminar flow shelf 9. The sliding rod 17 forms an extension and retraction structure with the cabinet 1 through the miniature electric push rod 20 and the connecting block 19, which is conducive to driving the miniature electric push rod 20. Through the connection of the connecting block 19, the sliding rod 17 is driven to extend and retract along the side wall of the cabinet 1, so that the movable laminar flow shelf 9 can be easily detached and disassembled in the cabinet.

[0027] Reference Figure 1 and Figure 2 The cabinet 1 has an air inlet 8 on its outer wall. Inside the cabinet 1, there is an FFU fan 10 located on one side of the air inlet 8. A high-efficiency filter 11 is installed on one side of the FFU fan 10. An electric heating tube 12 is installed on one side of the high-efficiency filter 11. A static pressure buffer box 13 is installed on the outer wall of the cabinet 1 to achieve the effect of convenient heating, transportation and circulation of gas.

[0028] Reference Figure 5 and Figure 6A micro servo motor 21 is provided on the side wall of the partition 4. A second gear 23 is rotatably connected to the side wall of the partition 4. A first gear 22 for driving the second gear 23 to rotate is fixedly connected to the output end of the micro servo motor 21. A turntable 24 is rotatably connected to the side wall of the partition 4. The rotation center of the turntable 24 is fixedly connected to the rotation center of the second gear 23 through a rotating shaft. The turntable 24 forms a rotating structure with the partition 4 through the first gear 22 and the second gear 23, which is conducive to the rotation of the first gear 22. Through the connection of the second gear 23, the turntable 24 is driven to rotate along the side wall of the partition 4, so as to drive the fixed column 25 to rotate synchronously.

[0029] Reference Figure 5 A connecting rod 26 is slidably connected to the side wall of the partition 4. A fixed column 25 is fixedly connected to the outer wall of the turntable 24 to drive the connecting rod 26 to slide back and forth along the side wall of the partition 4. The connecting rod 26 and the fixed column 25 are slidably connected. One end of the connecting rod 26 is fixedly connected to a tapping rod 28 located on one side of the movable laminar flow plate 9. The tapping rod 28 forms a lifting structure with the partition 4 through the connecting rod 26 and the fixed column 25. This facilitates the sliding of the fixed column 25 along the outer wall of the connecting rod 26, driving the tapping rod 28 to reciprocate up and down along the side wall of the partition 4, thereby achieving the effect of conveniently tapping and unblocking the flow holes on the surface of the movable laminar flow plate 9.

[0030] Reference Figure 5 and Figure 6 A limiting groove 27 is provided at the connection between the outer wall of the connecting rod 26 and the fixed column 25, which facilitates the sliding of the fixed column 25 by setting the limiting groove 27.

[0031] The working principle of this laminar flow clean cabinet is as follows: The FFU fan 10 is turned on, allowing outside air to be drawn into the cabinet through the air inlet 8. The drawn-in air undergoes high-efficiency filtration through the high-efficiency filter 11, and is heated and transported by the electric heating element 12. Through the flow holes on the surfaces of the fixed laminar flow shelf 5 and the movable laminar flow shelf 9, the heated air diffuses into the heating area inside the cabinet to disinfect items. To improve the ease of disassembly and reassembly of the movable laminar flow shelf 9 during prolonged use, the miniature electric push rod 20 is activated, pushing the connecting block 19. Under the connection of the spring 18 and the sliding rod 17, the locking block 16 slides along the inner wall of the connecting box 14, causing the locking block 16 to... 6 and the insertion rod 15 are not in contact, and the first sliding door 6 is opened to pull the movable laminar flow shelf 9 out of the cabinet 1, so as to achieve the effect of easy locking and disassembly of the movable laminar flow shelf 9. When the movable laminar flow shelf 9 circulates and transports heated air, in order to improve the effect of tapping and unblocking the flow holes on the surface of the movable laminar flow shelf 9, the micro servo motor 21 is turned on, and the rotation of the first gear 22 drives the second gear 23 to rotate. The rotation of the second gear 23 drives the fixed column 25 to rotate synchronously through the rotation of the turntable 24. With the opening of the limit groove 27, the connecting rod 26 is driven to extend and retract along the side wall of the partition 4, and the tapping rod 28 is driven to reciprocate to tap the surface of the movable laminar flow shelf 9, so as to effectively unblock the flow holes on the surface of the movable laminar flow shelf 9.
