[0024] In order to make the purpose, technical solution and advantages of the embodiments disclosed in the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present utility model.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. Specific embodiments

[0027] This embodiment provides a deflector cover (100) for an air purifier, such as Figure 1-Figure 3 As shown, the air guide cover (100) is arranged in the air flow channel of the air purifier, and the air guide cover (100) is a hemispherical arc surface (110) as a whole. The arc surface (110) is connected by a plurality of annular ribs (120) and radial ribs (130) with a certain width to form a mesh air outlet (111); the annular ribs (120) and the radial ribs (130) are oriented toward the center of the arc surface (110) along the width direction; and the air flow flows along the outer peripheral surface of the arc surface (110) toward the center of the arc surface (110).

[0028] In this embodiment, a deflector (100) is arranged in the air flow channel of the air purifier. The deflector (100) collects air flows in various directions into the hemispherical arc surface (110) of the deflector (100), thereby reducing the impact and collision between the air flow and the fan in the air purifier, and effectively reducing the noise of the air purifier.

[0029] Specifically, when the air flow converges toward the curved surface (110) under the action of the fan, the air flow speed and direction at different positions are different. The air flow passes through the mesh air outlet (111) of the curved surface (110), so that the air flow direction is changed and flows in the direction set by the curved surface (110), and the irregular air flow on the outer peripheral surface of the curved surface (110) can be divided into a plurality of directional air flows, thereby reducing the angle of change of the air flow direction when entering the curved surface (110).

[0030] In a more preferred embodiment, a plurality of annular ribs (120) are concentrically distributed on the curved surface (110), and the air flow area between any two adjacent annular ribs (120) is equal, so that the air flow is evenly divided between any two adjacent annular ribs (120), which can increase the air flow speed when the air flows out of the curved surface (110).

[0031] In a more preferred embodiment, the radial ribs (130) are evenly distributed between any two adjacent annular ribs (120), and the air flow areas of any air outlets (111) are equal, so that the air flow is evenly divided at any air outlet (111), which can maximize the air flow speed when the air flows out of the curved surface (110).

[0032] In a more preferred embodiment, the diameter of the sphere of the arc surface (110) is 90 mm-110 mm.

[0033] In a more preferred embodiment, the width of the annular rib (120) is 10 mm-20 mm; the width of the radial rib (130) is 5 mm-15 mm.

[0034] In a more preferred embodiment, the bottom of the arc surface (110) is a plane (140), and the plane (140) is provided with a fixing position (141) for connecting with an external component. Specifically, the fixing position (141) can be a screw hole.

[0035] The above are only specific embodiments of the present invention, so that those skilled in the art can understand or implement the present disclosure. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
