[0029] like Figures 1 to 5 As shown, a filter combined housing comprises a box body 1 and a box cover 2 which can be combined together, the box body 1 is arranged at the upper end of the box cover 2, a rotating rod 13 is fixedly connected to a corner of the lower end of the box cover 2, the lower end of the rotating rod 13 extends into the interior of the box body 1 and is rotatably connected to the box body 1, a height-adjustable lifting plate 5 is arranged in the middle of the box body 1, a filter element 6 for making the filter work normally is installed on the lifting plate 5, a lifting assembly is arranged inside and on one side of the box cover 2, the lifting assembly is used to drive the lifting plate 5 to adjust the height, and the lifting assembly is driven by the rotation of the rotating rod 13;

[0030] The filter element 6 on the filter is installed on a lift plate 5 that can be raised and lowered inside the box body 1, and the lifting and lowering of the lift plate 5 is driven by the switch rotation of the box cover 2. When the technician turns the box cover 2, the lifting plate 5 can be driven to rise through the lifting assembly, so that the filter element 6 rises to the upper end of the box body 1, thereby increasing the operating space of the technician and improving the convenience of maintenance for the technician. When the filter element 6 rises to the upper end of the box body 1, the surrounding air circulation speed can be utilized to improve the heat dissipation effect. Through the setting of the lifting assembly, the complexity and time consumption of the technician's maintenance can be reduced, the replacement time of components can be reduced, and the overall operating efficiency can be improved.

[0031] Further, such as Figures 1 to 4 As shown, a handle 3 is fixedly connected at a corner of the upper end of the box cover 2, and the lifting assembly includes a driving gear 14 arranged at a corner of one side of the box body 1, the lower end of the rotating rod 13 is fixedly connected to the middle part of the driving gear 14, one side of the driving gear 14 is meshingly connected with a driven gear 19, and the middle part of the lower end of the driven gear 19 is fixedly connected with a transmission rod 8, and the lower end of the transmission rod 8 is engaged and rotatably connected with the box body 1, and the lower end of the outer wall of the transmission rod 8 is fixedly connected with a driving pulley 12, and the external transmission of the driving pulley 12 is connected with a belt 10, and the middle part of the inner bottom surface of the box body 1 is engaged and rotatably connected with a threaded column 22, and the lower end of the outer wall of the threaded column 22 is fixedly connected with a driven pulley 21, and the end of the belt 10 away from the driving pulley 12 is transmission-connected to the driven pulley 21, and the driven pulley 21 is connected to the driving belt The transmission ratio of the wheel 12 is 5:1. The upper end of the threaded column 22 is threadedly connected with a threaded sleeve 9. The upper end of the threaded sleeve 9 is fixedly connected to the middle part of the lower end of the lifting plate 5. One side of the middle part of the inner bottom surface of the box body 1 is engaged and rotatably connected with two limit rollers 11. Both sides of the belt 10 are respectively in contact with the two limit rollers 11. The four corners of the lower end surface of the lifting plate 5 are fixedly connected with guide rods 23. The lower end of the guide rod 23 is slidably connected with a guide cylinder 24. The lower end of the guide cylinder 24 is fixedly connected to the box body 1. Two slide grooves 29 are provided on both sides of the inner wall of the box body 1. Slide blocks 25 are fixedly connected to both ends of both sides of the lifting plate 5. One end of the slide block 25 is slidably connected to the inside of the slide groove 29. The corner of the box body 1 is located outside the driving gear 14 and is fixedly connected with a protective cover 15.

[0032] By manually rotating the handle 3 at the upper end of the box cover 2, the handle 3 drives the rotating rod 13 fixedly connected thereto to rotate, and the lower end of the rotating rod 13 is fixedly connected to the middle part of the driving gear 14, so the rotation of the rotating rod 13 will drive the driving gear 14 to rotate, and the driving gear 14 is meshed and connected with the driven gear 19, so the driven gear 19 will rotate with the rotation of the driving gear 14, and the transmission rod 8 fixedly connected to the middle part of the lower end of the driven gear 19 will rotate accordingly, and the driving pulley 12 at the lower end of the outer wall of the transmission rod 8 is connected to the driven pulley 21 through the belt 10, and the transmission ratio of the driven pulley 21 to the driving pulley 12 is 5:1, which means that the driven pulley 21 will rotate five times when the driving pulley 12 rotates one circle, thereby achieving the effect of speed change, and the driven pulley 21 is fixedly connected to the lower end of the outer wall of the threaded column 22, so the threaded column 22 will rotate accordingly, and the threaded column 22 will rotate accordingly. The column 22 is threadedly connected to the threaded sleeve 9. When the threaded column 22 rotates, the threaded sleeve 9 will rise and fall vertically on the threaded column 22. The upper end of the threaded sleeve 9 is fixedly connected to the middle part of the lower end of the lifting plate 5. Therefore, the lifting plate 5 will rise and fall with the lifting of the threaded sleeve 9. At the same time, the lifting plate 5 is slidably connected to the guide cylinder 24 through the guide rod 23, and the sliding block 25 is slidably connected to the slide groove 29, which ensures the stability and guidance of the lifting plate 5 during the lifting process. The entire lifting process is smooth and reliable, and by adjusting the rotation direction and strength of the handle 3, the lifting height of the lifting plate 5 can be accurately controlled, thereby meeting the installation, debugging and maintenance requirements of the filter element. In addition, the provision of the protective cover 15 effectively protects the transmission components such as the driving gear 14, prevents the intrusion of dust and debris, and extends the service life of the lifting assembly.

[0033] Further, such as Figure 3 As shown, a fixed rod 20 is fixedly connected to the middle of the upper end surface of the driven gear 19, and the upper end of the fixed rod 20 is fixedly connected to the driven bevel gear 18, and one side of the upper end of the driven bevel gear 18 is meshedly connected to the driving bevel gear 17, and the middle of the driving bevel gear 17 is fixedly connected to the rotating shaft 16, one end of the rotating shaft 16 is engaged and rotatably connected to the box body 1, and the other end of the rotating shaft 16 is fixedly connected to the fan blade 4;

[0034] The driven gear 19 is not only connected to the driving gear 14 through the transmission rod 8 at its lower end, but also connected to the driven bevel gear 18 through the fixed rod 20 fixedly connected in the middle of its upper end surface. When the driving gear 14 rotates to drive the driven gear 19 to rotate, the rotation of the driven gear 19 will drive the fixed rod 20 and the driven bevel gear 18 to rotate together. One side of the upper end of the driven bevel gear 18 is meshed with the driving bevel gear 17, which means that when the driven bevel gear 18 rotates, it will drive the driving bevel gear 17 to rotate in the opposite direction. The middle part of the driving bevel gear 17 is fixedly connected with a rotating shaft 16, and one end of the rotating shaft 16 is engaged and rotatably connected with the housing 1, ensuring that the driving bevel gear 17 and the fan blades 4 can rotate smoothly in the housing 1. The other end of the rotating shaft 16 is fixedly connected with the fan blades 4. Therefore, when the driving bevel gear 17 rotates, it will drive the fan blades 4 to rotate together. The rotation of the fan blades 4 can generate airflow, which is used to blow air on the surface of the filter element 6 to blow away the dust on the surface, thereby improving the convenience of subsequent maintenance by technicians.

[0035] Further, such as Figures 5 and 6 As shown, a limiting hole 26 is provided at a corner of the upper end of the box body 1, and a telescopic spring seat 28 is fixedly connected to the inner bottom surface of the limiting hole 26, and a limiting column 27 is fixedly connected to the upper end of the telescopic spring seat 28, and the upper end of the limiting column 27 is spherical;

[0036] At a corner of the upper end of the box body 1, a limiting hole 26 is designed. This limiting hole 26 not only provides an installation position for specific mechanical components, but also serves to limit the box cover 2. A telescopic spring seat 28 is fixedly connected to the inner bottom surface of the limiting hole 26. The telescopic spring seat 28 is a device that can be extended and retracted as needed and provide elastic force. The upper end of the telescopic spring seat 28 is fixedly connected to a limiting column 27. The upper end of the limiting column 27 is designed to be spherical. In actual use, a groove matching the limiting column 27 is provided at the lower end of the box cover 2. When the box cover 2 is closed, the upper end of the limiting column 27 is clamped in the groove to complete the limiting work.

[0037] Further, such as Figure 1 to Figure 2 As shown, through holes 7 are provided at the lower middle ends of both ends of the box body 1, and rounded corners are provided at both ends of the through holes 7;

[0038] The two through holes 7 provide convenience for the wiring of the filter element 6 . The rounded corners at both ends of the through hole 7 can reduce the damage to the surface of the wire caused by the corners of the through hole 7 when the lifting plate 5 moves, thereby increasing the service life of the wire.
