The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

Referring to fig. 1 to 4, an air cleaning assembly 100 according to an embodiment of the first aspect of the present invention, the air cleaning assembly 100 being used to clean air, as shown in fig. 1, the air cleaning assembly 100 according to an embodiment of the present invention includes a housing 10 and a rotary cleaning member 20.

Specifically, the housing 10 has an air inlet 11 and an air outlet 12, a rotating chamber 10a communicating the air inlet 11 and the air outlet 12 is defined in the housing 10, the rotating purifying member 20 is rotatably disposed in the rotating chamber 10a, and external air can enter the housing 10 from the air inlet 11, pass through the rotating chamber 10a, and then be discharged from the air outlet 12.

In an alternative embodiment of the present invention, the air purifying assembly 100 further comprises a water distribution assembly (not shown), and optionally, the water distribution assembly may distribute water at an upstream side of the rotating purifying member 20. It should be noted that "upstream" means the area where the main air flow flows to the rotating purifying member 20 with the rotating purifying member 20 as a boundary, and as shown in fig. 1, the main air flow flows from bottom to top, and the areas between the air inlet 11 and the rotating purifying member 20 and below the air inlet 11 are all upstream of the rotating purifying member 20.

The water distribution component distributes water on the upstream side of the rotary purification member 20, and the water distribution component can capture and adsorb impurities (such as dust particles) in the air flow entering from the air inlet 11, so that the air is purified by the water, and a part of the water falls under the action of self gravity. The other part of water can continuously flow upwards, and the other part of water is intercepted when meeting the rotating purification piece 20 rotating at high speed, further, the rotating purification piece 20 rotates at high speed, and the rotating purification piece 20 throws the intercepted water liquid onto the inner wall of the rotating cavity 10a under the action of centrifugal force, so that the effect of gas-liquid separation is achieved.

In an alternative embodiment of the present invention, as shown in fig. 1, the air inlet 11 is located at the lower end of the rotating chamber 10a, the air outlet 12 is located at the upper end of the rotating chamber 10a, and the rotating purification member 20 is provided with a plurality of meshes arranged at intervals. The air flow enters the rotating cavity 10a from the air inlet 11, and along with the high-speed rotation of the rotating purifying member 20, the air flow flows upwards through the meshes on the rotating purifying member 20, and the liquid flowing upwards is blocked by the rotating purifying member 20 rotating at high speed, i.e. the rotating purifying member 20 intercepts the liquid flowing upwards, so as to avoid the liquid flowing downstream of the rotating purifying member 20 along with the air flow, i.e. the downstream refers to the area where the main air flow passes through the rotating purifying member 20, such as the area from the rotating purifying member 20 to the air outlet 12 and above the air outlet 12 in fig. 1, and meanwhile, the rotating purifying member 20 rotating at high speed can throw the intercepted liquid to the inner wall of the rotating cavity 10 a.

In addition, the inner wall of the rotating cavity 10a is provided with an anti-escape region 21, and the anti-escape region 21 is arranged flush with the rotating purifying member 20, which means that the axial height of the anti-escape region 21 is consistent with the axial height of the rotating purifying member 20, for example, the middle position of the anti-escape region 21 in the axial direction is in the same horizontal plane with the rotating purifying member 20, and the anti-escape region 21 is arranged around at least a part of the circumferential direction of the rotating purifying member 20, and may extend for one circle along the circumferential direction of the rotating purifying member 20 or extend for a part along the circumferential direction of the rotating purifying member 20.

In order to ensure a high speed rotation of the rotating purification member 20 within the rotating chamber 10a, so that the apparatus operates more smoothly, a gap 13 is left between the inner wall of the rotating chamber 10a and the outer edge of the rotating purification member 20, by providing the inner wall of the rotating chamber 10a with an escape prevention area 21 flush with the rotating decontaminating member 20, when the rotating purifying member 20 rotates at a high speed, the liquid droplets trapped in the overflowing gas are thrown to the inner wall surface of the rotating chamber 10a, the inner wall surface of the escape prevention region 21 prevents the liquid from splashing when the liquid hits the wall surface, and, when the liquid amount is large, the liquid impacting the wall surface at high speed can not form liquid drops which are difficult to slide, interrupted or uninterrupted liquid films on the wall surface, can effectively avoid the phenomenon that part of splashed liquid drops are wrapped by airflow from the gap 13, that is, it is ensured that the air flow does not entrain part of the water liquid to be discharged from the air outlet 12, and the air-liquid separation effect of the air purification assembly 100 is improved.

According to the air purification assembly 100 of the embodiment of the invention, the anti-escape area 21 flush with the rotary purification piece 20 is arranged on the inner wall of the rotary cavity 10a, so that the liquid intercepted by the rotary purification piece 20 is prevented from splashing around when being thrown onto the inner wall of the rotary cavity 10a, the water is prevented from being carried out from the gap 13 by the airflow, and the effect of gas-liquid separation is remarkable.

As shown in fig. 1, it should be noted that the rotating purifying member 20 is connected to a motor through a driving shaft 14, and the motor drives the rotating purifying member 20 to rotate at a high speed, so as to achieve the effect of separating purified air and gas-liquid.

According to an embodiment of the present invention, the axial dimension of the escape-preventing region 21 is larger than the axial dimension of the rotating purifying member 20, and the orthographic projection of the rotating purifying member 20 on the inner wall of the rotating chamber 10a is located at the axial middle of the escape-preventing region 21, that is, the position of the rotating purifying member 20 in the axial direction is opposite to the middle of the escape-preventing region 21, so that when the rotating purifying member 20 rotates at a high speed, the rotating purifying member 20 almost uniformly throws the liquid droplets on the escape-preventing region 21, specifically, when the rotating purifying member 20 throws the liquid droplets on the inner wall of the rotating chamber 10a due to the centrifugal force, the liquid droplets may be thrown obliquely upward of the outer edge of the rotating purifying member 20, and also obliquely downward of the outer edge of the rotating purifying member 20, and of course, the axial dimension and the position of the escape-preventing region are arranged as above, the liquid drops thrown out by the rotary purifying piece 20 are all distributed on the escape-proof area 21, so that the liquid thrown out by the rotary purifying piece 20 in the direction is prevented from splashing and being entrained by the airflow, and the effect of gas-liquid separation is improved.

According to an embodiment of the present invention, the anti-escape areas 21 include a plurality of anti-escape areas 21, the plurality of anti-escape areas 21 are arranged at intervals in the circumferential direction of the inner wall of the rotating cavity 10a, when the rotating purification member 20 rotating at a high speed throws out liquid droplets in the circumferential direction of the rotating cavity 10a, the liquid droplets will splash on the plurality of anti-escape areas 21, and the liquid droplets can be prevented from splashing, even if the liquid droplets impact in the gap 13 between two adjacent anti-escape areas 21, for example, two adjacent anti-escape areas 21 have a smaller distance, the smaller distance itself can also play a role in preventing the liquid droplets impacting the wall surface at a high speed from splashing, that is, the air flow is prevented from entraining the liquid.

As shown in fig. 1, according to an embodiment of the present invention, at least a portion of the escape-preventing region 21 is configured as a rough surface, so that, when the rotating purifying member 20 rotates at a high speed, droplets in the air flow are caught and thrown toward the escape-preventing region 21, so that, by configuring at least a portion of the escape-preventing region 21 as a rough region, water does not splash due to the surface characteristics of the rough region when the water is thrown onto the rough region, and at the same time, water hardly forms droplets or a water film on the rough region, and the water easily slides off the wall surface of the rough region, thereby preventing the water from being entrained into the downstream by the air flow near the gap 13.
