The blades 40 are longitudinally distributed so that the air flow generated by the wind wheel 4 after rotation flows in the direction of the side wall 10 of the housing 1. The wind wheel top 43 circumferentially forms a first rotating surface 41 on one surface facing the fan blade and taking the longitudinal rotation axis of the wind wheel 4 as the center; the wind wheel bottom 44 circumferentially forms a second rotating surface 42 on the surface facing the fan blade, with the longitudinal rotation axis of the wind wheel 4 as the center.

In some embodiments, the first rotor surface 41 is inclined with respect to the longitudinal rotation axis of the rotor 4, and similarly, the second rotor surface 42 is inclined with respect to the longitudinal rotation axis of the rotor 4, i.e. the first rotor surface 41 and the second rotor surface 42 form an angle with the transverse plane of the rotor 4. In other embodiments, the included angle between the first rotation surface 41 and the second rotation surface 42 and the transverse plane of the wind wheel 4 may be zero. The first and second surfaces 41 and 42 may be planar or curved, and may be set as required by the specific embodiment. This arrangement has the advantage that, for example, by arranging the corresponding swirl face obliquely to the longitudinal axis of rotation, the size of the swirl face can be increased as much as possible in a limited space of the entire air cleaner, so that a greater air volume and air flow rate can be produced.

In a preferred embodiment, as shown in fig. 1 and 4, the first wind scooper 2 is near the top 11 of the housing, and includes a motor installation space 20 for accommodating the motor 6 for driving the wind wheel 4, a motor carrying part 22 disposed at the bottom of the motor installation space 20, and a flow guiding part 21 forming the motor installation space 20 together with the motor carrying part 22. The side of the guide 22 facing the rotor 4 surrounds the motor support 22, forming an annular first guide surface 21, which first guide surface 21 extends from the edge of the motor support 22 to the side wall 10 of the housing 1. The first guiding surface 21 corresponds to the first rotating surface 41 of the wind wheel 4, and may be planar or curved. In the preferred embodiment, referring to fig. 3, the rotor top 43 of the rotor 4 corresponds to the motor installation space 20 of the first wind guiding cover 2, a concave structure 45 with a concave middle is formed on the rotor top 43, the first rotor surface 41 surrounds the bottom 46 of the concave structure, and a ring-shaped first rotor surface 41 is formed circumferentially. Through forming the motor and setting up the space, can accomodate the motor in to do not need to occupy extra air purifier's space and come the installation motor, greatly reduced whole air purifier's overall dimension.

In the preferred embodiment, the first rotating surface 41 is parallel to the first guiding surface 21, so that the air flow generated by the wind wheel 4 flows along the first guiding surface 21 to the side wall 10 of the housing, and the resistance of the air flow is reduced.

As shown in fig. 5, the second wind scooper 3 includes an accommodating space 30 for accommodating the bottom of the wind wheel 4, and a second guiding portion 32 disposed around the accommodating space 30, wherein a surface of the second guiding portion 32 facing the wind wheel 4 surrounds the accommodating space 30 to form an annular second guiding surface 31, and the second guiding surface 31 extends from an edge of the accommodating space 30 to the side wall 10 of the housing 1. In one embodiment, the wind wheel bottom 44 of the wind wheel 4 is disposed in the accommodating space 30, and the second rotation surface 42 of the wind wheel 4 is parallel to the second guiding surface 31 of the second guiding cover 3, so that the airflow generated by the wind wheel 4 flows along the second guiding surface 31 to the side wall 10 of the housing, and the resistance of the airflow is reduced. The second guide surface 31 corresponds to the second rotation surface 42 of the wind wheel 4, and may be planar or curved. Similarly, by providing the second swirl face obliquely to the longitudinal rotation axis, the size of the swirl face can be increased as much as possible in a limited space of the entire air cleaner, thereby enabling a larger air volume and air flow rate.

The first and second rotor surfaces 41, 42 of the rotor 4 are inclined in the same direction relative to the longitudinal axis of rotation of the rotor 4, and may be inclined towards the top or bottom of the housing 1, and in the embodiment shown in the drawings, the first and second rotor surfaces 41, 42 are inclined towards the top of the housing 1. In other embodiments, the configuration may be set according to the requirements of a specific embodiment, for example: the inclination directions of the first rotating surface 41 and the second rotating surface 42 relative to the longitudinal rotation axis of the wind wheel 4 can also be inclined towards the bottom of the shell 1 according to specific requirements; or one of the screws is inclined toward the top of the housing 1 and the other is inclined toward the bottom of the housing 1, and the inclination angle and the inclination direction thereof may be different from each other, which is not limited. In other embodiments, the first and second rotor surfaces 41, 42 may also be perpendicular to the longitudinal axis of rotation of the rotor 4, in which embodiment the annular outlet channel 5 is perpendicular to the longitudinal axis of rotation of the rotor 4.

In combination with fig. 6, the air purifier provided by the utility model has the advantages that the first air guiding surface 21 of the first air guiding cover 2, the second air guiding surface 31 of the second air guiding cover 3 and the wind wheel 4 jointly define the annular air outlet channel 5, so that after the wind wheel 4 is driven to rotate, the air filtered clean inside the air purifier forms air flow towards the side wall 10 of the shell, the air flow flows along the air outlet channel 5 to the area on the side wall 10 of the shell 1 corresponding to the annular air outlet channel 5, and the air outlet holes 100 are arranged on the side surface of the air purifier, so that the aim of exhausting the clean air from the side edge of the air purifier is achieved. The defect that the resistance to the discharge of air flow generated after the rotation of the wind wheel of the traditional air purifier is large is overcome. And the air is discharged from the side face of the air purifier, so that the application scene of the air purifier can be increased, and the requirements of different users are met.

In addition, since the first rotating surface 41 of the wind wheel 4 is parallel to the first guiding surface 21, and the second rotating surface 42 is parallel to the second guiding surface 31, the resistance is smaller and the performance of the air purifier is improved in the process that the air flow generated after the wind wheel 4 rotates flows to the air outlet 100.

The shape, size and density of the air holes 100 may be flexibly set according to specific requirements, and are not limited herein.
