[0032] As described above, the separation base 2 is a single-end open groove structure, after installation, the opening of the separation base 2 is in close contact with the flow guide 1, so that the connection part of the two will not seep water or air leakage, the bottom surface of the separation base 2 is provided with a first spacing layer 21 and a second spacing layer 22, wherein the first spacing layer 21 and the second spacing layer 22 are both circular ring shapes, the first end (lower edge) of the first spacing layer 21 and the second spacing layer 22 is respectively in close contact with the bottom surface of the separation base 2, the second end (upper edge) of the first spacing layer 21 and the second spacing layer 22 is respectively in abutment with the flow guide 1, further, in some embodiments, one of the first spacing layer 21 and the second spacing layer 22 can also be in abutment with the flow guide 1, for example, only the second spacing layer 22 is in abutment with the flow guide 1, the second spacing layer 22 is arranged in the first spacing layer 21, the axis of the second spacing layer 22 and the axis of the first spacing layer 21 coincide, the first spacing layer 21 and the second spacing layer 22 will sequentially separate the gas-liquid separation cavity from outside to inside into a first water and liquid collecting area 23, a gas flow introduction area 24 and a second water and liquid collecting area 25, wherein the area between the first spacing layer 21 and the shell of the separation base 2 is the first water and liquid collecting area 23, the area between the first spacing layer 21 and the second spacing layer 22 is the gas flow introduction area 24, and the area surrounded by the second spacing layer 22 is the second water and liquid collecting area 25, wherein a gas flow inlet 211 is arranged at the tangent of the first spacing layer 21, that is, the opening direction of the gas flow inlet 211 is at a certain angle with the first spacing layer 21, so that the water-containing gas flow can enter the gas flow introduction area 24 in a tangential direction of the first spacing layer 21, and the water-containing gas flow can flow along the inner wall of the first spacing layer 21 and form a rotating gas flow in the gas flow introduction area 24, the gas flow inlet 211 is preferably arranged close to the bottom surface of the separation base 2;

[0034] It is worth mentioning that the air inlet is arranged at the lower side, and the first water vapor inlet 212 and the second water vapor inlet 11 are both arranged at the upper side. Under the action of the suction force of the motor, the water-containing air flow will flow from the lower side to the upper side along the inner wall of the first spacing layer 21 after forming a rotating air flow in the air flow introduction area 24, and after reaching the first water vapor inlet 212, most of the water in the rotating air flow will be thrown into the first water liquid collection area 23 from the first water vapor inlet 212 due to the action of the centrifugal force. The water droplets gathered will flow to the bottom of the first water liquid collection area 23 under the action of gravity. Under the action of the blockage of the first spacing layer 21 and the height difference with the upper first water vapor inlet 212, the water remaining at the bottom of the first water liquid collection area 23 will not re-enter the rear air passage.

[0035] At the same time, the remaining water-containing air flow will enter the flow guide pipe 14 along the tangential direction of the flow guide pipe 14 to perform secondary gas-liquid separation. The water separated by the secondary separation will flow into the second water liquid collection area 25 from the flow guide pipe 14. After two times of gas-liquid separation, the water content in the water-containing air flow has been greatly reduced. Under the action of the fan 3, the water-containing air flow with small mass can be quickly discharged from the air duct of the fan 3 without being left or condensed in the air duct.

[0036] It is worth mentioning that the tangential direction in the present application can be the tangent direction at a certain point, but the approximately tangential direction, for example, the included angle with the tangent direction is within the range of 0-15°, is also included in the tangential direction described in the present application.

[0041] In one embodiment, the first water vapor inlet 212 is arranged obliquely from bottom to top along the direction of the rotating air flow.

[0042] As mentioned above, the first water vapor inlet 212 is arranged obliquely from bottom to top along the rotating direction of the rotating air flow, so that the water can be thrown out of the first water vapor inlet 212 along the rotating centrifugal direction of the rotating air flow from bottom to top, which extends the centrifugal rotating track to a certain extent and increases the force of water throwing. In combination with the opening direction of the first water vapor inlet 212, the water vapor will not hit the side wall of the first water vapor inlet 212.

[0045] In one embodiment, the opening direction of the second water-vapor inlet 11 is at an angle with the flow guide pipe 14, so that the water-containing gas flow can enter the cyclone separation cavity 141 in a tangential direction of the flow guide pipe 14.

[0046] As described above, the second water-vapor inlet 11 is arranged in the tangential direction of the flow guide pipe 14, so that the water-containing gas flow can enter the cyclone separation cavity 141 in a tangential direction of the flow guide pipe 14, without hitting the side wall of the second water-vapor inlet 11.
