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; the central column is internally provided with a collecting cavity C;
The air inlet pipe is communicated with the first separation cavity through an air inlet extension air duct; after entering from the air inlet pipe, the air is sent to the air inlet HEPA after being purified by an air inlet extension air duct, 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.
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 extension air duct, the outer side wall of the primary filter is a porous and circular 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.
The air duct air-pressing ring is arranged near the side wall of the central column in an inclined mode, and a conical air guide ring 702 is formed in the middle of the air duct air-pressing ring. Specifically, the lower end of the air duct air pressing ring near the central column side wall is retracted, the inclined surface is inward, air can be guided to the first separation cavity, and enough space can be reserved for an air pressing opening.
The annular air guide part is communicated with the air guide ring.
The inner diameter of the air duct separation ring is larger than that of the annular air guide part.
The upper part of the secondary multi-cone filter is provided with a multi-cone separating device 402, a plurality of small-sized separating cones are arranged on the multi-cone separating device, and the small-sized separating cones are communicated with the collecting cavity of the central column.
The bottom of the dust cup is provided with a openable bottom cover 8.

Working principle: wind containing water or dust enters the device through the air inlet, and further enters the inside of the primary filter directly through the air inlet extension air duct along the arrow, and the extension air duct provides a trend of rotating along the center of the filter, so that the entering wind can rotate along the air duct inside the primary filter, (the rotating benefit is that the wind can orderly pass through the sewage tank without generating unnecessary vortex), after the wind enters the first separation cavity through the guiding of the air duct air pressing ring, the wind can rotate from top to bottom near the center position in the first separation cavity due to inertia, the wind turns upwards and turns back outwards when approaching the bottom cover of the sewage tank quickly, and turns back from bottom to top along the position near the inner side of the air duct separation ring, but the diameter of the first separation cavity is larger than the inner diameter of the primary filter (namely the annular air guide part), so that the wind speed is reduced, and the high-density garbage can be deposited in the first separation cavity due to gravity and inertial centrifugal force. Relatively light dust and part of water can continue to cross the separating ring along with wind, and under the action of the wind channel wind-pressing ring, a turning-back effect is formed again at the tip of the wind-pressing ring, wind upwards moves, the dust and the water strike the inner wall of the dust cup under the action of inertia, and the dust and the water are deposited downwards under the dual action of gravity and inertia (namely, the water and the dust are collected downwards in the second accommodating part, and relatively clean wind flows into the air supply channel through the filtering part). After the 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 adopts several separation techniques of centrifugation, turning back, wall collision, speed reduction, sedimentation and the like, thereby realizing the separation of water vapor or dust gas.
Although embodiments of the present invention have been disclosed above, it is not limited to the details and embodiments shown, it is well suited to various fields of use for which the invention is suited, and further modifications may be readily made by one skilled in the art, and the invention is therefore not to be limited to the particular details and examples shown and described herein, without departing from the general concepts defined by the claims and the equivalents thereof.
