A placement table is fixedly connected to the lower side of the purification box. An air pump is fixedly connected to the upper side of the placement table. The air pump is connected to the dust discharge pipe. Four installation components are arranged inside the purification box.

[0008] Furthermore, the installation component includes an installation seat. The installation seat is located inside the purification box. Corresponding threaded groove holes are provided on both the installation seat and the purification box. A fixing bolt is threadedly connected to one side of the installation seat. The installation seat is fixedly connected to the purification box through the fixing bolt.

[0009] Furthermore, a sliding groove is provided on one side of the installation seat. A slider is slidably connected to the upper side of the sliding groove. One end of the slider is fixedly connected with a limiting column (), and the limiting column () is located inside the installation seat (). The end of the slider away from the limiting column is fixedly connected with an activated carbon filter plate.

[0010] Further, a HEPA filter plate is slidably connected inside the purification box.

[0011] Further, an exhaust pipe is connected through the upper end of the purification box.

[0012] Further, handles are provided on one side of both the activated carbon filter plate and the HEPA filter plate.

[0013] The advantages of the present utility model compared with the existing technology are as follows: By providing the activated carbon filter plate and the HEPA filter plate, the present utility model collects the air with dust, filters the particulate dust through the activated carbon filter plate, eliminates the odor through the HEPA filter plate, and finally discharges the processed air into the air through the exhaust pipe. And through the cooperation of the installation components and the handles provided in the present utility model, the two filter plates can be pulled out for cleaning after being used for a certain period of time.
