[0064] As shown in Figure 1 , Figure 2 and Figure 4 , the air outlet grille 108 comprises a plurality of air guide portions 170; the plurality of air guide portions 170 are arranged in a ring shape, the height of the air guide portion 170 in the plurality of air guide portions 170 close to the axis of the fan assembly 110 is higher than the height of the air guide portion 170 in the plurality of air guide portions 170 away from the axis of the fan assembly 110; or each air guide portion 170 in the plurality of air guide portions 170 extends along the radial direction of the fan assembly 110, and the end of the air guide portion 170 close to the axis of the fan assembly 110 is higher than the end of the air guide portion 170 away from the axis of the fan assembly 110.

[0065] In this embodiment, the air outlet grille 108 comprises a plurality of air guide portions 170; the plurality of air guide portions 170 are arranged in a ring shape, and the height of the air guide portions 170 close to the axis of the fan assembly 110 is higher than that of the air guide portions 170 away from the axis of the fan assembly 110, so that the air outlet grille 108 is arranged in an inclined manner. Each of the plurality of air guide portions 170 extends in the radial direction of the fan assembly 110, and the end of the air guide portion 170 close to the axis of the fan assembly 110 is higher than the end of the air guide portion 170 away from the axis of the fan assembly 110, so as to achieve the inclined arrangement of the air outlet grille 108. By arranging the air outlet grille 108 in an inclined downward manner, the projection area of the air outlet grille 108 in the horizontal direction is increased, so that the air outlet area can be increased. The increase of the air outlet area means that the air can pass through the purifier 100 more quickly, so as to improve the air purification efficiency. Moreover, by arranging the air outlet grille 108 in an inclined downward manner, compared with the inclined upward manner, the distance between the air outlet grille 108 and the guide vanes 114 can be reduced or unchanged, so that after the air outlet grille 108 in the inclined downward manner cooperates with the guide vanes 114, the air can be guided to flow out at a certain angle, so that the distribution of the discharged air is more uniform.

[0066] Specifically, in the purifier 100, Figure 1 , the arrow A represents the height direction of the purifier 100, the arrow F represents the axis of the fan assembly 110, and the arrow G represents the radial direction of the fan assembly 110.

[0067] Specifically, in the purifier 100, Figure 4 , the arrow D represents the circumferential direction of the air outlet grille 108.

[0068] The purifier 100 provided in this embodiment further comprises the following technical features in addition to the technical features of the above-mentioned embodiments.

[0069] As shown in Figure 1 and Figure 3 , the fan assembly 110 comprises the first support 112 and the plurality of guide vanes 114. The plurality of guide vanes 114 are arranged in the circumferential direction of the first support 112; and the plasma assembly 128 is located between two adjacent guide vanes 114 of the plurality of guide vanes 114.

[0070] In this embodiment, the fan assembly 110 includes a first support 112 and a plurality of guide vanes 114. The plurality of guide vanes 114 are arranged along the circumference of the first support 112 to achieve installation of the plurality of guide vanes 114. By providing the plurality of guide vanes 114, the air flow can be guided, improving the convenience of the air outlet of the purifier 100. The plasma assembly 128 is located between two adjacent guide vanes 114 of the plurality of guide vanes 114 to achieve installation of the plasma assembly 128. When the air flow passes the position of the guide vanes 114, the plasma assembly 128 can ionize the air to generate positive and negative ions, thereby killing bacteria or viruses in the air to achieve further purification of the air.

[0073] In this embodiment, in the height direction of the purifier 100, the side of the guide vane 114 connected to the first support 112 to the side of the guide vane 114 close to the first housing 106 is arranged downwardly inclined, so that the plurality of guide vanes 114 can form an inclined surface. The inclined surface formed by the guide vanes 114 has a larger area than a horizontal straight surface, directly increasing the effective area of the air outlet 152, so that the air can flow out of the purifier 100 more smoothly. The increase in the area of the air outlet 152 and the optimization of the air flow distribution enable the air to pass through the purifier 100 more quickly and be distributed more evenly in the indoor space. Under the same conditions, the larger the air outlet area of the air outlet grille 108, the better the performance of the purifier 100 is generally. The guide vane 114 with the inner high and outer low shape is more conducive to pushing the air flow from the inner high to the low, and is more conducive to the outward diffusion of the air flow, thereby guiding the air flow passing through the plasma assembly 128 to flow away from the first electronic control assembly 120, avoiding direct contact between the ions generated by the plasma assembly 128 and the first electronic control assembly 120, and reducing the risk of damage to the first electronic control assembly 120 due to ion impact.

[0126] In this embodiment, the curvature of the wind guide surface 164 decreases from the side of the wind guide surface 164 close to the fan assembly 110 to the side of the wind guide surface 164 close to the shell assembly 102, so as to adjust the wind guide surface 164, so that the wind blown vertically from the air outlet grille 108 can be effectively guided to the horizontal direction, so that the air supply range of the purifier 100 is more extensive. Horizontal air supply helps to enhance the air circulation in the room, so that the purifier 100 can quickly purify the air in the room and uniformly distribute to each corner, improving the purification efficiency. The arc line of the third shell 146 is from inside to outside, and the curvature transition is more and more smooth, and finally gradually transitions to an approximately horizontal trend, ensuring that the airflow is approximately horizontally blown out during the outward diffusion process, completing the wind blown vertically from the air outlet grille 108 to the horizontal direction, thereby improving the user experience.

[0127] The embodiment provides a purifier 100, in addition to the technical features of the above-mentioned embodiments, the embodiment further includes the following technical features.

[0128] The air outlet grille 108 extends in an arc shape from the side close to the fan assembly 110 to the side close to the shell assembly 102 of the air outlet grille 108.

[0129] In this embodiment, the air outlet grille 108 extends in an arc shape from the side close to the fan assembly 110 to the side close to the shell assembly 102, and the arc-shaped air outlet grille 108 can effectively guide the airflow blown out from the fan assembly 110 to flow out of the air outlet 152 more smoothly. The airflow direction of the airflow passing through the plasma assembly 128 is gradually away from the installation position of the first electronic control assembly 120, which reduces the residence time of the airflow inside the purifier 100. The ions generated by the wall plasma assembly 128 contact the first electronic control assembly 120, thereby improving the purification efficiency. Through the arc-shaped design, the air outlet grille 108 can make the airflow blow out in a more gentle and uniform manner, avoiding the situation of local airflow being too strong or too weak, thereby optimizing the air supply effect and improving the user experience.

[0130] Specifically, the top cover 148 is in a planar form, which is convenient for users to place articles or decorate other ornaments, etc.

[0131] Specifically, the top of the third shell 146 can support the top cover 148, and the lower end of the third shell 146 is connected with the air outlet grille 108, thereby playing a role of connecting the upper and lower parts. Meanwhile, the outer surface of the third shell 146 is an arc surface with a gradually gentle curvature transition, which cooperates with the arc surface of the air outlet grille 108 to form the air outlet 152 flow guide layer of the air duct 156 system.

[0132] Specifically, the air outlet grille 108 is the air outlet 152 of the purifier 100, and the outer surface of the air outlet 152 is an arc surface with an inner high and outer low inclined arc transition, which is beneficial to the flow guidance of the airflow.

[0133] Specifically, the fan assembly 110 includes a motor 116 and a fan wheel 118, and the fan wheel 118 is driven by the motor 116 to stir air to form an airflow.

[0134] Specifically, as shown in Figure 1 the purifier 100 further includes a filter screen 166, which is arranged in the air inlet grille 104 and serves as a core component for purification and adsorption of the purifier 100. The filter screen 166 can purify the air sucked into the air inlet 154. The bottom of the air duct 156 is an air inlet, and the airflow passing through the filter screen 166 directly passes through the grid-shaped air inlet at the bottom of the air duct 156 and enters the inside of the air duct 156.

[0135] Specifically, the first bracket 112 is a motor bracket, which is the most important load-bearing component of the purifier 100 and internally installs the motor 116. The motor 116 is assembled in the middle region of the first bracket 112, and the outer ring of the guide vane 114 adopts an inclined design, and the outer ring height of the guide vane 114 is lower than the inner ring height.

[0136] Specifically, the fan assembly 110 further comprises a volute formed with an air duct 156, and the top of the volute is connected with the first support 112 and fixed by screws.

[0137] Specifically, the purifier 100 further comprises a base 168 connected with the shell assembly 102 and located on the side of the shell assembly 102 away from the fan assembly 110, which serves as the base of the purifier 100 and can support the weight of the purifier 100.
