[0023] Specifically, the transmission assembly includes a motor 8 and a linkage unit. The motor 8 is fixedly connected to one side of the top of the cabinet 1. A reciprocating screw 9 is rotatably connected to one side of the interior of the cabinet 1. The top of the reciprocating screw 9 extends to the top of the cabinet 1 and is fixedly connected to the output end of the motor 8. The lifting block 5 is threadedly connected to the outside of the reciprocating screw 9. A rotating rod 10 is rotatably connected to one side of the interior of the cabinet 1 close to the reciprocating screw 9. A first gear 11 is fixedly connected to the outside of the reciprocating screw 9. The top of the rotating rod 10 extends to the top of the cabinet 1 and is fixedly connected to a second gear 12. The first gear 11 is meshed with the second gear 12. The fan 6 can be rotated through the linkage unit. The linkage unit includes a first pulley 14. The first pulley 14 is rotatably connected to the top of the lifting block 5, both sides of the outside of the rotating rod 10 are fixedly connected to the limit blocks 13, the first pulley 14 is slidably connected to the outside of the limit blocks 13, both sides of the inside of the lifting block 5 are rotatably connected with the rotating shaft 15, the top of the rotating shaft 15 extends to the top of the lifting block 5 and is fixedly connected with the second pulley 16, the first pulley 14 and the two second pulleys 16 are respectively connected by transmission belts 17, the bottoms of the two rotating shafts 15 are fixedly connected with second bevel gears 19, the outer sides of the two fans 6 are fixedly connected with first bevel gears 18, the two first bevel gears 18 are respectively meshed with the two second bevel gears 19, and the two first bevel gears 18 are set in opposite directions.

[0024] Through the above technical scheme, reagents of different specifications can be stored through the placement plate 21 inside the cabinet 1 for easy classification, and the air purification device 7 and the motor 8 are started. The output end of the motor 8 drives the reciprocating screw 9, so that the reciprocating screw 9 drives the lifting block 5 to reciprocate and move under the limit of the inner wall of the cabinet 1 through a threaded connection relationship. At the same time, the reciprocating screw 9 drives the external first gear 11 to rotate, and the first gear 11 then drives the second gear 12 and the rotating rod 10 to rotate through a meshing relationship. The rotating rod 10 then drives the first pulley 14 to rotate through the external limit block 13. Since the first pulley 14 is slidably connected to the limit block 13, the lifting block 5 can drive the first pulley 14 to move synchronously during the lifting process. During the rotation process, the first pulley 14 can drive the two second pulleys 16 and the corresponding rotating shaft 15 to rotate through the transmission belt 17, and the rotating shaft 15 then drives the second bevel gear 19 at the bottom to rotate, so that the second bevel gear 19 is rotated through The meshing relationship drives the first bevel gear 18 and the fan 6 to rotate, and because the two first bevel gears 18 are set in opposite directions, the two first bevel gears 18 can drive the corresponding fans 6 to rotate in opposite directions, so that the interior of the cabinet 1 is ventilated through the air exhaust port 3 and the air inlet 4 respectively through the two oppositely rotating fans 6 in cooperation with the air purification device 7 and the bellows 20, the pungent smell of the reagent is extracted and purified, and then the pure air is discharged into the interior of the cabinet 1, thereby achieving the purification of the interior of the cabinet 1. At the same time, the reciprocating lifting block 5 can drive the fan 6 to reciprocate and lift, so that the space above the multiple placement plates 21 can be purified, and the barrier seal between the partition plate 2 and the placement plate 21 can effectively avoid the cross-odor caused by the common storage of multiple reagents of different specifications, which not only improves the air purification effect of the device, but also solves the problem of waste of power resources caused by setting multiple sets of exhaust fans due to the need for sealing when storing multiple reagents of different specifications.

[0025] Specifically, bellows 20 are provided on both sides of the interior of the lifting block 5 extending to the outside of the cabinet 1, and one end of the bellows 20 away from the lifting block 5 extends to the interior of the air purification device 7 and is fixedly connected to the air purification device 7. A placement plate 21 is fixedly connected equidistantly to the exhaust port 3 and the air inlet 4 inside the cabinet 1 and on one side of the partition 2, and a cabinet door 22 is installed on the outside of the cabinet 1.

[0026] Through the above technical solution, the extracted gas can be conveniently transmitted through the provided bellows 20, thereby improving the gas transmission efficiency, and the cabinet body 1 can be sealed through the provided cabinet door 22, thereby ensuring the storage sealing performance.

[0027] Specifically, the air purification device 7 and the motor 8 are both electrically connected to the external controller, the diameters of the two second pulleys 16 are smaller than the diameter of the first pulley 14 , the diameter of the first bevel gear 18 is smaller than the diameter of the second bevel gear 19 , and the diameter of the second gear 12 is smaller than the diameter of the first gear 11 .

[0028] Through the above technical solution, since the diameter of the two second pulleys 16 is smaller than the diameter of the first pulley 14, the diameter of the first bevel gear 18 is smaller than the diameter of the second bevel gear 19, and the diameter of the second gear 12 is smaller than the diameter of the first gear 11, the corresponding fan 6 can be driven to rotate rapidly through the first bevel gear 18 while the reciprocating screw 9 drives the lifting block 5 to move at normal speed.

[0029] When in use, reagents of different specifications can be stored through the placement plate 21 inside the cabinet 1 for easy classification. The air purification device 7 and the motor 8 are started, and the output end of the motor 8 drives the reciprocating screw 9, so that the reciprocating screw 9 drives the lifting block 5 to perform reciprocating and undulating motion under the limit of the inner wall of the cabinet 1 through a threaded connection relationship. At the same time, the reciprocating screw 9 drives the external first gear 11 to rotate, and the first gear 11 then drives the second gear 12 and the rotating rod 10 to rotate through a meshing relationship. The rotating rod 10 then drives the first pulley 14 to rotate through the external limit block 13, and due to the sliding between the first pulley 14 and the limit block 13 The lifting block 5 is connected, so the lifting block 5 can drive the first pulley 14 to move synchronously during the lifting process. During the rotation process, the first pulley 14 can drive the two second pulleys 16 and the corresponding rotating shaft 15 to rotate through the transmission belt 17. The rotating shaft 15 then drives the second bevel gear 19 at the bottom to rotate, so that the second bevel gear 19 drives the first bevel gear 18 and the fan 6 to rotate through the meshing relationship. Since the two first bevel gears 18 are set in opposite directions, the two first bevel gears 18 can drive the corresponding fans 6 to rotate in opposite directions, thereby cooperating with the purification device 7 and the bellows 2 through the two oppositely rotating fans 6. The interior of the cabinet 1 is ventilated through the air extraction port 3 and the air inlet 4 respectively, the pungent smell of the reagent is extracted and purified, and then the pure air is discharged into the interior of the cabinet 1, so as to achieve the purification of the interior of the cabinet 1. At the same time, the reciprocating lifting block 5 can drive the fan 6 to lift and lower, so that the space above the multiple placement plates 21 can be purified. The partition seal between the partition plate 2 and the placement plate 21 can effectively avoid the cross-smell caused by storing multiple reagents of different specifications together, which not only improves the air purification effect of the device, but also solves the need for sealing when storing multiple reagents of different specifications. As for the problem of power resource waste caused by setting up multiple sets of exhaust fans, the bellows 20 can be used to conveniently transmit the extracted gas, thereby improving the gas transmission efficiency. The cabinet door 22 can be used to seal the cabinet body 1, thereby ensuring the storage sealing performance. Since the diameter of the two second pulleys 16 is smaller than the diameter of the first pulley 14, the diameter of the first bevel gear 18 is smaller than the diameter of the second bevel gear 19, and the diameter of the second gear 12 is smaller than the diameter of the first gear 11, the first bevel gear 18 can drive the corresponding fan 6 to rotate rapidly while the reciprocating screw 9 drives the lifting block 5 to move at a normal speed.
