[0007] Preferably, one end of the spring is fixedly connected to the limiting seat, and the other end of the spring is fixedly connected to the fixing cover. The spring can automatically reset the limiting seat through its elastic force.

[0008] Preferably, an air inlet pipe is fixedly connected to the upper end of the box cover, the limiting seat is slidably connected to the fixed cover, the limiting seat is slidably connected to the rotating ring, and the limiting seat is slidably connected to the connecting ring. The limiting seat can limit the position of the connecting ring.

[0009] Preferably, the one-way exhaust mechanism includes an exhaust port, and the interior of the T-shaped tube is fixedly connected with multiple evenly distributed exhaust ports. A sealing cap is hinged to the lower end of the exhaust port, and a fixing plate is fixedly connected to the middle of the inner wall of the exhaust port.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model adds a rotating ring, an internal gear ring, and a limiting seat inside the filter box. During the filtration of exhaust gas through the dust collection bag, the gear and internal gear ring drive the dust collection bag to rotate. During the rotation of the dust collection bag, the dust generated during filtration can be disturbed, thereby effectively preventing the dust collection bag from clogging. Furthermore, the limiting seat limits the position of the dust collection bag. When it is necessary to clean the dust collection bag, simply disengage the limiting seat from the rotating ring to remove the dust collection bag for cleaning.

[0013] 2. This utility model adds an air outlet, a sealing cover, and a tension spring to the T-shaped tube. When it is necessary to exhaust air into the treatment box, the air pressure drives the sealing cover to disengage from the air outlet, thus allowing exhaust to proceed. After exhaust is completed, the tension spring returns to its original position. The tension spring can use its elasticity to drive the sealing cover to seal the air outlet, thereby effectively preventing the backflow of the medicine. Attached Figure Description

A filter box 2 is fixedly connected to the upper left side of the base 1, and a treatment box 3 is fixedly connected to the upper right side of the base 1. A connecting pipe 4 is fixedly connected to the right end of the filter box 2. A T-shaped pipe 5 is fixedly connected to one end of the connecting pipe 4 inside the treatment box 3. A one-way exhaust mechanism 6 is provided on the T-shaped pipe 5. A box cover 7 is threadedly connected to the upper end of the filter box 2. A rotating ring 8 is mounted on the upper part of the inner wall of the filter box 2 through a bearing. A connecting ring 9 is slidably connected inside the rotating ring 8. A dust collection bag 10 is fixedly connected to the lower end of the connecting ring 9. An internal gear ring 11 is fixedly connected to the upper end of the rotating ring 8. A gear 12 is mounted inside the box cover 7 through a bearing. A motor 13 is mounted on the upper end of the box cover 7. Two symmetrically distributed fixed covers 14 are fixedly connected to the upper end of the connecting ring 9. A handle 15 is slidably connected inside the fixed cover 14. A limit seat 16 is fixedly connected to one end of the handle 15 near the rotating ring 8. A spring 17 is provided on the outer side of the handle 15.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The output shaft of motor 13 is fixedly connected to gear 12. Gear 12 meshes with internal gear ring 11. Gear 12 can drive rotating ring 8 to rotate through internal gear ring 11. One end of spring 17 is fixedly connected to limit seat 16, and the other end of spring 17 is fixedly connected to fixed cover 14. Spring 17 can automatically reset limit seat 16 through elastic force. Air inlet pipe 18 is fixedly connected to the upper end of box cover 7. Limit seat 16 is slidably connected to fixed cover 14, limit seat 16 is slidably connected to rotating ring 8, and limit seat 16 is slidably connected to connecting ring 9. Limit seat 16 can limit the connecting ring 9.

[0023] Please see Figure 1 , Figure 3 , Figure 5 The one-way exhaust mechanism 6 includes an exhaust port 61. Multiple evenly distributed exhaust ports 61 are fixedly connected inside the T-shaped tube 5. A sealing cover 62 is hinged to the lower end of the exhaust port 61. A fixing plate 63 is fixedly connected to the middle of the inner wall of the exhaust port 61. A tension spring 64 is provided below the fixing plate 63. The sealing cover 62 can block the exhaust port 61. One end of the tension spring 64 is fixedly connected to the fixing plate 63, and the other end of the tension spring 64 is fixedly connected to the sealing cover 62.

[0024] The specific implementation process of this utility model is as follows: In use, the air inlet pipe 18 discharges the exhaust gas into the interior of the filter box 2. Then, the motor 13 is started, and the motor 13 drives the gear 12 to rotate. The gear 12 drives the rotating ring 8 to rotate through the internal gear ring 11. The rotating ring 8 drives the dust collection bag 10 to rotate through the connecting ring 9. During the rotation, the dust collection bag 10 can disturb the dust generated by internal filtration, thereby preventing the dust collection bag 10 from clogging and ensuring filtration efficiency. The filtered exhaust gas is discharged into the interior of the T-shaped pipe 5 through the connecting pipe 4. When the pressure of the exhaust gas is greater than the elastic force of the tension spring 64, the sealing cover 62 deflects, allowing the exhaust gas to be discharged into the liquid medicine inside the treatment box 3. After the exhaust is completed, the tension spring 64 returns to its original position. The tension spring 64 can use its elastic force to drive the sealing cover 62 to seal the air outlet 61, preventing the liquid medicine from flowing back.

[0025] When it is necessary to clean the dust bag 10, open the box cover 7 and pull the handle 15. The handle 15 drives the limit seat 16 to move and compresses the spring 17. When the limit seat 16 disengages from the rotating ring 8, the limit on the connecting ring 9 can be released. Then the connecting ring 9 and the dust bag 10 can be removed for cleaning.
