In addition, the wind wheel assembly 120 further includes a second wind guiding member 124, specifically, a second wind guiding member 124 is disposed at one end of the wind wheel 122 near the flow guiding assembly 140, one end of the second wind guiding member 124 is connected with the wind wheel 122, and the other end of the second wind guiding member is inclined and extends towards the side where the flow guiding assembly 140 is located and away from the direction of the central axis of the wind wheel assembly 120, so that when the wind wheel 122 rotates to disturb the airflow, the airflow can be redirected when flowing out of the air outlet of the first airflow channel, and the airflow can flow out of the air outlet of the first airflow channel according to a specified direction.

In a specific embodiment, as shown in fig. 8, further, an outer diameter of an end of the first wind guiding member 123 near the second wind guiding member 124 is larger than an outer diameter of an end of the second wind guiding member 124 far from the first wind guiding member 123.

In another specific embodiment, as shown in fig. 1 and 8, the housing 121 further comprises a first housing and a second housing that are connected, the first housing being disposed farther from the baffle assembly 140 than the second housing; wherein, an included angle α1 is formed between a plane where the first air guiding member 123 is close to the side surface of the first housing and a plane where the inner surface of the first housing is located, and an included angle α2 between a plane where the first air guiding member 123 is far away from the side surface of the first housing and the central axis of the wind wheel assembly 120 satisfies 0.9.ltoreq.α1/α2.ltoreq.1.

In this embodiment, the housing 121 is defined to include a first housing and a second housing that are coupled, the first housing being disposed farther from the flow directing assembly 140 than the second housing. Specifically, an included angle α1 is formed between a plane where a side surface of the first air guiding member 123 near the first housing and a plane where an inner surface of the first housing is located, and an included angle α2 is formed between a plane where a side surface of the first air guiding member 123 far away from the first housing is located and a central axis of the wind wheel assembly 120, and an angle defined by a ratio of α1 to α2 is approximately equal to an angle defined by α1 to 1.1, that is, an inclination angle of the first air guiding member 123 is approximately equal to an angle formed by the first air guiding member 123 and an inner wall of the first housing, so that an airflow direction when the airflow leaves the wind wheel 122 is defined. And the impact noise generated by the air flow striking the inner wall of the housing 121 can be reduced, further reducing the noise generated by the air treatment device 100 when in operation. The life of the housing 121 may also be extended.

In yet another specific embodiment, as shown in fig. 8, further, an included angle α3 between a plane of the second wind guiding member 124 adjacent to the side surface of the first wind guiding member 123 and the central axis of the wind wheel assembly 120 is greater than an included angle α2 between a plane of the first wind guiding member 123 adjacent to the side surface of the second wind guiding member 124 and the central axis of the wind wheel assembly 120.

In this embodiment, the angle α3 between the plane of the side surface of the second wind guiding member 124 adjacent to the first wind guiding member 123 and the central axis of the wind wheel assembly 120 is defined to be larger than the angle α2 between the plane of the side surface of the first wind guiding member 123 facing away from the first housing and the central axis of the wind wheel assembly 120, that is, the inclination angle of the second wind guiding member 124 is defined to be larger than the inclination angle of the first wind guiding member 123. Thus, when the air flow leaves the wind wheel 122 and enters the air flow channel, the air flow is guided again when the air flow flows out of the air outlet of the wind wheel assembly 120, so that the air flow can flow out of the air outlet of the wind wheel assembly 120 according to the specified direction.

The air flow guiding component 140 is disposed at the air outlet of the first air flow channel, and the air flow flowing out of the air outlet of the first air flow channel is guided by the guide vane 141 of the guide component 140, and when the air flow flows out of the air outlet of the first air flow channel, the air flow is convenient to flow to the guide vane 141 of the guide component 140 by using the inclination angle of the second air guiding piece 124 to be larger than the inclination angle of the first air guiding piece 123, so as to reduce the impact loss generated by the air flow and the guide vane 141 and improve the air outlet efficiency.

It should be noted that, the range of the included angle α2 between the plane where the side surface of the first air guiding member 123 facing away from the first housing and the central axis of the wind wheel assembly 120 may be limited, specifically, the angle α2 is 25 ° or less and 40 ° or less, so as to further limit the airflow direction when the airflow leaves the wind wheel 122 and enters the airflow channel, and after the wind wheel 122 performs disturbance work on the airflow, the airflow is extruded out of the first air guiding member 123 and enters the first airflow channel, so that the impact of the airflow on the inner wall of the housing 121 can be reduced, and further the impact loss of the airflow is reduced. And the impact noise generated by the air flow striking the inner wall of the housing 121 can be reduced, further reducing the noise generated by the air treatment device 100 when in operation. The life of the housing 121 may also be extended.

In still another specific embodiment, as shown in fig. 7 and 8, further, in the radial direction of the wind wheel assembly 120, the distance b between the side of the guide vane 141 near the first guide 130 and the center of the body and the outer diameter D5 of the end of the second guide 124 far from the first guide 123 satisfy 2b < D5.

In this embodiment, a distance b between a side of the guide vane 141 near the first guide member 130 and the center of the body and an outer diameter D5 of an end of the second guide member 124 away from the first guide member 123 in the radial direction of the wind wheel assembly 120 are defined to satisfy 2b < D5, specifically, a distance between a side of the guide vane 141 near the first guide member 130 and the center of the body, that is, a distance between an inner side of the guide vane 141 and the center of the body, and 2b is a distance between inner sides of the guide vane 141 oppositely disposed in the radial direction of the wind wheel assembly 120.

It can be understood that the air flows out from the air outlet of the first air flow channel and then flows to the guide vane 141 of the guide assembly 140, the air is redirected by the guide vane 141, and the distance between the inner sides of the guide vanes 141 which are oppositely arranged along the radial direction of the wind wheel assembly 120 is smaller than the outer diameter of one end of the second wind guiding piece 124, which is far away from the first wind guiding piece 123, so that when the air flows out from the air outlet of the wind wheel assembly 120, the air is ensured to flow to the guide vane 141 better, and then the air is guided by the guide vane 141.

In addition, the distance between the inner sides of the guide vanes 141 arranged opposite to each other along the radial direction of the wind wheel assembly 120 is smaller than the outer diameter of the end, away from the first wind guide member 123, of the second wind guide member 124, so that when the air flows out from the air outlet of the first air flow channel, the impact between the air flow and the guide vanes 141 can be reduced, and then the impact noise generated when the air flow and the guide vanes 141 impact is reduced, and the noise generated when the air treatment device 100 works is further reduced. Moreover, the impact loss generated by the air flow and the guide vane 141 can be reduced, thereby improving the overall purifying amount of the air treatment device 100.

It should be noted that, the distance b between the side of the guide vane 141 near the first guide member 130 and the center of the body and the outer diameter D5 of the end of the second air guide member 124 far from the first air guide member 123 satisfy 0.9.ltoreq.2b/d5.ltoreq.1. Therefore, when the air flows out from the air outlet of the first air flow channel, the impact between the air flow and the guide vane 141 can be reduced, and then the impact noise generated when the air flow and the guide vane 141 impact is reduced, and the noise generated when the air treatment device 100 works is further reduced. Moreover, the impact loss generated by the air flow and the guide vane 141 can be reduced, thereby improving the overall purifying amount of the air treatment device 100.

Fifth embodiment:

as shown in fig. 2 and 9, further, the air treatment device 100 further includes an air outlet assembly 170, where the air outlet assembly 170 is disposed on the housing 110 and is located at the air outlet 112, and the air outlet assembly 170 includes a plurality of air outlet grills 171, and the plurality of air outlet grills 171 are disposed near the housing 110 at intervals along the circumferential direction of the air outlet 112; wherein, the distance d between two adjacent air outlet grids 171 is more than or equal to 5mm and less than or equal to 6mm.

In this embodiment, it is defined that the air treatment device 100 further comprises an air outlet assembly 170, specifically, the air outlet assembly 170 is connected to the housing 110, and the air outlet assembly 170 is located at the air outlet 112, i.e. after the air flow is decelerated and pressurized through the second air flow passage, is discharged into the room through the air outlet assembly 170. Further, the air outlet assembly 170 includes a plurality of air outlet grids 171, and by providing the air outlet grids 171, the airflow velocity can be further reduced, so as to reduce noise generated by the airflow velocity.

In addition, by providing the air outlet grill 171, foreign objects and the like can be prevented from falling into the air treatment apparatus 100 from the air outlet 112, which may cause damage to components in the air treatment apparatus 100, and the service life of the air treatment apparatus 100 can be prolonged.

Further, the spacing d between two adjacent air outlet grids 171 is specifically limited to be equal to or smaller than 5mm and equal to or smaller than 6mm, so that the problem that external foreign matters fall into the air treatment device 100 to damage parts in the air treatment device 100 can be further prevented. It can be understood that, if the interval between two adjacent air outlet grids 171 is too small, the flow area of the air flowing through the air outlet 112 will be reduced, and if the interval between two adjacent air outlet grids 171 is too large, the foreign objects cannot be effectively prevented from falling.
