Existing clean rooms mainly achieve air filtering and purification by installing a combined fan filter device, thereby ensuring the cleanliness of the air input into the clean room. However, in actual use of the existing combined fan filter device, due to the long-term operation of the equipment, excessive foreign matter remaining on the surface of the filter mechanism will cause blockage, affecting the filtering effect, and requires regular replacement. When replacing the filter mechanism of the existing combined fan filter device, it is necessary to shut down the machine for operation, which is more troublesome, and the shutdown is likely to cause the clean environment in the clean room to be destroyed, thereby causing greater economic losses. In addition, the existing filter mechanism is mainly fixed and installed by bolts, which is more troublesome to disassemble and assemble, and it is difficult to ensure the sealing between the filter mechanism and the box after installation. For this reason, in view of the above problems, a combined clean room air filter device is now designed to better meet the actual use needs. Summary of the invention

[0029] A sealed box door 2 is fixedly installed on the left end face of the filter box 1, and a fan 3 is connected to the upper end face of the filter box 1, and an air inlet 4 is connected to the fan 3; a high-efficiency filter 801 is installed on the mounting frame 8, and an iron plate 802 is also fixed symmetrically on the mounting frame 8, and the iron plate 802 is magnetically connected to the magnet 702, and the mounting frame 8 and the movable plate 7 are nested; a piston rod 902 is arranged in the cylinder 9, and the piston rod 902 is slidably connected to the filter box 1, and the position of the piston rod 902 corresponds to the position of the movable plate 7, and a piston head 903 is also fixed on the piston rod 902, and the piston head 903 is slidably connected in the cylinder 9; one end of a spring 904 is fixed to the right end of the piston head 903, and the other end of the spring 904 is fixed in the cylinder 9;

[0030] When using the combined clean room air filtration device, Figure 1-Figure 4 As shown, first assemble the entire device. When installing the mounting frame 8 and the high-efficiency filter 801, by opening the sealed box door 2 and cooperating with the nesting effect between the mounting frame 8 and the movable plate 7, the mounting frame 8 and the high-efficiency filter 801 can be installed. Then, by cooperating with the magnetic attraction between the iron plate 802 and the magnet 702, the positioning effect of the mounting frame 8 and the high-efficiency filter 801 can be achieved. Finally, close the sealed box door 2. In actual use, the device is powered by an external power supply, such as Figure 1-Figure 3 As shown, at this time, by starting the fan 3 and cooperating with the action of the air inlet 4, the outside air can enter the filter box 1. At this time, the air is filtered and purified through the high-efficiency filter 801 installed on the rear movable plate 7. The purified air enters the fixed box 11 through the guide pipe 10. During long-term use, when the high-efficiency filter 801 installed on the rear movable plate 7 needs to be replaced due to excessive impurities, at this time, it is only necessary to start the motor 5 to drive the first gear 6 to rotate. Through the sliding action between the first gear 6 and the first convex tooth plate 701, the rear movable plate 7 can be moved to the left and the front movable plate 7 can be moved to the right until the high-efficiency filter 801 on the front movable plate 7 is just moved between the two vertical plates in the filter box 1. At this time, the rear movable plate 7 seals and blocks the rear opening of the filter box 1, so that the air is filtered and purified through the high-efficiency filter 801 on the front movable plate 7, thereby realizing the replacement of the high-efficiency filter 801, without stopping the operation, which is convenient and simple. When the front movable plate 7 moves to the right and contacts the piston rod 902, as shown in FIG. Figure 2 , Figure 3 and Figure 5As shown, at this time, the piston rod 902 is forced to slide to the right, and synchronously drives the piston head 903 to slide in the cylinder 9, so that the air in the cylinder 9 enters the airbag 703 through the conduit, and the inflation effect of the airbag 703 is realized. When the high-efficiency filter 801 on the front movable plate 7 moves to the right to the required position, the airbag 703 is inflated and expanded, and the squeezing, fixing and sealing effect of the mounting frame 8 can be realized, thereby ensuring the stability of the installation of the mounting frame 8 and the sealing between the movable plate 7 and the mounting frame 8, avoiding gas leakage, and effectively ensuring the air purification effect;

[0031] An air outlet 1101 is arranged on the right side of the fixed box 11, and a surface cooler 1102, a heating tube 1103 and a partition 1104 are installed in the fixed box 11 from left to right, respectively, and the distance between the lower end surface of the partition 1104 and the lower end surface of the inner side of the fixed box 11 is 5cm-8cm, and a vertical rod 1105 is also fixed symmetrically front and back in the fixed box 11; a mounting shaft 12 is also connected to the fixed box 11 with a bearing, and a fan plate 1201 is evenly fixed on the mounting shaft 12 at equal angles, and a second gear 1202 is also fixed symmetrically front and back on the mounting shaft 12, and the mounting shaft 12 is arranged on the right side of the partition 1104; the second gear 1202 is meshedly connected with the transmission gear 13, and the transmission gear 1 The diameter of the second gear 1202 is larger than that of the second gear 1202, and the transmission gear 13 is connected to the fixed box 11 by a bearing, and a convex shaft 1301 is fixed to the transmission gear 13; an adjustment plate 14 is connected to the air outlet 1101 by a bearing, and the adjustment plates 14 are evenly spaced in the air outlet 1101; a third gear 1401 is fixed to the adjustment plate 14 symmetrically in the front and back, and the third gear 1401 is meshed with the second convex tooth rod 1402, and a connecting rod 1403 is fixed to the right side of the second convex tooth rod 1402, and the connecting rod 1403 is slidably connected to the vertical rod 1105, and the groove on the connecting rod 1403 is slidably connected to the convex shaft 1301;

[0032] During use of the device, if Figure 1-Figure 9As shown, the purified air enters the fixed box 11 through the guide pipe 10. At this time, by starting the surface cooler 1102 or the heating tube 1103, the gas can be cooled or heated to better meet the actual use needs. When the gas flows in the fixed box 11, the partition 1104 is used to make the gas flow to the right only through the gap between the lower side of the partition 1104 and the fixed box 11, and is discharged to the clean room through the air outlet 1101. At this time, under the action of the airflow and in conjunction with the action of the fan plate 1201, the mounting shaft 12 and the second gear 1202 can be rotated. Through the reduction transmission action between the second gear 1202 and the transmission gear 13, the transmission gear 13 and the cam shaft 1301 can be rotated synchronously. In conjunction with the cam shaft 13 01 and the sliding action between the groove on the connecting rod 1403 can make the connecting rod 1403 move up and down in an orderly manner. The sliding guiding action between the connecting rod 1403 and the vertical rod 1105 can ensure the stability of the movement of the connecting rod 1403. When the connecting rod 1403 moves up and down, it can also drive the second convex tooth rod 1402 to move up and down in an orderly manner. The meshing transmission action between the second convex tooth rod 1402 and the third gear 1401 can make the adjustment plate 14 swing under force, thereby realizing the direction adjustment effect of the adjustment plate 14. The wind direction of the gas discharged from the air outlet 1101 can be adjusted through the swing of the adjustment plate 14, so that the gas is evenly dispersed in the clean room. This is the working principle of the combined clean room air filter device.
