[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] Referring to Figure 1 , Figure 2 and Figure 3 , the air deflector of the embodiment of the utility model, including cover body 100, the middle part of cover body 100 is provided with the air inlet hole 110 that penetrates, the side wall of cover body 100 is provided with multiple protrusions 200, one side of protrusion 200 is provided with air outlet hole 210, air outlet hole 210 penetrates to the inside of cover body 100, and is communicated with air inlet hole 110, wherein, the connecting position of protrusion 200 and the inner side wall of cover body 100 is smooth transition (such as Figure 3 B place), and protrusion 200 is provided with multiple, multiple protrusions 200 are spaced apart around the circumference of cover body 100.

[0022] Due to the driving force of the driving mechanism (such as the motor of the dust collector), the airflow enters the inside of the air deflector from the outside through the air inlet hole 110, and flows in the air deflector. In the process of flowing, it will contact the circumferential inner side of the air deflector, and the inner side of the air deflector will guide the airflow, making the airflow spiral. When the airflow flows to the position of the protrusion 200, the smooth transition connecting part will guide the airflow to a certain extent, making part of the airflow flow to the air outlet, and the other part of the airflow continues to form a spiral airflow in the cover body 100. With multiple evenly distributed air outlet holes 210, the airflow can flow uniformly from multiple air outlet holes 210. In summary, the airflow is uniformly distributed to different air outlet holes 210, and the smooth transition connecting position is used to reduce the obstruction to the airflow, effectively reducing the noise generated by the airflow.

[0023] It should be noted that the protrusion 200 has a flow guide surface 220, which is connected to the inner side of the cover body 100. The flow guide surface 220 is a curved surface extending from the side of the cover body 100 to the outside of the cover body 100. The flow guide surface 220 is connected to the smooth transition connecting position, that is, the flow guide surface 220 and the inner side of the cover body 100 are smoothly transitioned. When the airflow flows nearby, the airflow can be guided from the inner side of the cover body 100 to the flow guide surface 220 and finally flow out of the air outlet hole 210, reducing the obstruction to the airflow while also diffusing the flow direction of the airflow.

[0024] Further, referring to Figure 1 , the opening of the air outlet hole 210 is trapezoidal. The trapezoidal air outlet hole 210 can comb the airflow, making the airflow flow more smoothly and improving the noise reduction effect.

[0025] It should be noted that, referring to Figure 1 , the corners of the opening of the air outlet hole 210 are rounded. This makes the airflow receive less obstruction and avoids resonance between the airflow and the inner wall, which produces noise.

[0026] As an optimized embodiment, the protrusions 200 are provided with 42 to 44, and the entire cover body 100 is provided with 42 to 44 air outlets 210, so that the air outlet is uniform.

[0027] In some embodiments, in order to improve the strength of the cover body 100 and avoid damage to the cover body 100, a plurality of reinforcing ribs 120 are arranged in the cover body 100, the reinforcing ribs 120 are connected between the inner surface and the side wall of the cover body 100, and the reinforcing ribs 120 are in a meandering shape.

[0028] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by the ordinary skilled in the art without departing from the purpose of the utility model.
