A first separation cavity A is formed between the central column and the air duct separating ring, a second separation cavity B is formed between the inner wall of the lower part of the dust cup and the air duct separating ring, and the first separation cavity and the second separation cavity are communicated through an air pressing opening of the air duct air pressing ring; a collecting cavity C is arranged in the central column;
the air inlet pipe is communicated with the first separation cavity through an air inlet extending air channel; after entering from the air inlet pipe, the air is purified by an air inlet extending air channel, a first separation cavity, an air pressing opening, a second separation cavity, a filtering part, an air supply channel and a multi-cone separation device and then is sent to an air inlet HEPA.
The primary filter is provided with an interlayer, the inner side wall of the primary filter is an annular air guide part 301 connected with the air inlet extending air channel, the outer side wall of the primary filter is a porous and tubular filtering part 302, and an air supply channel D communicated with the multi-cone separating device is formed by the interlayer between the annular air guide part and the filtering part.
One side wall of the air duct air pressing ring close to the central column is obliquely arranged, so that a tapered air guide ring 702 is formed in the middle of the air duct air pressing ring. Specifically, the lower end of a side wall of the air duct air pressing ring close to the center column is retracted, the inclined plane is inward, air can be guided to the first separation cavity, and enough space can be reserved for the air pressing opening.
The annular air guide part is communicated with the air guide ring.
The inner diameter of the air duct separating ring is larger than that of the annular air guide part.
The upper part of the second-stage multi-cone filter is a multi-cone separating device 402, a plurality of small separating cones are arranged on the multi-cone separating device, and the small separating cones are communicated with a collecting cavity of the central column.
The bottom of the dust cup is a bottom cover 8 which can be opened and closed.
The edge of the bottom cover is provided with an upward folded edge 801, the bottom cover is provided with an annular bulge 802, and when the bottom cover is closed, the bulge is abutted against the lower end of the air duct separating ring.
The inner side of the bulge forms a first accommodating part E, and a second accommodating part F is formed between the folded edge and the bulge.

The first containing part is mainly used for containing dust particles with high density, and the second containing part is mainly used for containing sewage and dust particles with low density.
The working principle is as follows: wind containing water or dust enters the interior of the equipment through the air inlet, and further enters the interior of the primary filter directly through the air inlet extension air channel along an arrow and the extension air channel provides a trend of rotating along the center of the filter, so that the entering wind can rotate along the air channel in the primary filter, (the rotation has the advantages that the wind can pass through the sewage tank orderly without generating unnecessary vortex) and enters the first separation cavity through the guide of the air channel air pressing ring, the wind rotates from top to bottom near the center in the first separation cavity due to inertia, the wind returns to the outer side upwards when approaching the bottom cover of the sewage tank, and rotates from bottom to top near the inner side of the air channel separation ring, but the wind speed is reduced because the diameter of the first separation cavity is larger than the inner diameter (namely, the annular wind guide part) of the primary filter, dense waste can settle in this chamber due to gravity and inertial centrifugal forces. The relatively light dust and part of water can continue to cross the separating ring along with the wind, and under the effect of wind channel wind pressing ring, a turn-back effect is formed at the tip of the wind pressing ring again, the wind goes upwards, the dust and water impact the inner wall of the dust cup under the action of inertia, and are deposited downwards under the dual actions of gravity and inertia (namely, the water and the dust are collected downwards in the second accommodating part, and the relatively clean wind direction enters the air supply channel through the filtering part). After wind enters the second separation cavity through the wind channel wind pressing ring, the wind speed is further reduced because the inner wall of the dust cup (the second separation cavity) is larger than the diameter of the first separation cavity, and convenience is provided for dust and water sedimentation. The structure uses several separation technologies of centrifugation, turning back, wall collision, speed reduction, sedimentation and the like, thereby realizing the separation of water, gas or dust and gas.
