Rotor impeller and motor with same

[0078] Example one

[0079] A moving impeller includes an upper piece, a middle piece and a lower piece, and a toothed structure is provided on the outer edge of the upper piece at the wind outlet.

[0080] The number of tooth-shaped structures is at least three, and the shape of the tooth-shaped structures can be one of rectangular, V-shaped, semi-circular, elliptical, and involute.

[0081] Please refer to Figure 5 The top sheet structure of the moving impeller provided in this embodiment is shown in the figure. The outer edge 11 of the top sheet 1 at the air outlet is provided with a toothed structure 13, and the outer edge 12 of the top sheet 1 at the air inlet is not provided It has a toothed structure. When the vacuum cleaner is working, the moving impeller rotates at a high speed, and the air is sucked in from the air inlet and discharged through the suction channel. When passing through the toothed structure 13 of the outer edge 11 of the air outlet of the upper sheet 1, it is

[0085] Example two

[0086] A moving impeller includes an upper piece, a middle piece and a lower piece. The outer edge of the middle piece at the air inlet and / or the air outlet is provided with a toothed structure.

[0087] The number of the tooth-shaped structure is one or more than one, and the shape of the tooth-shaped structure may be one of a rectangle, a V-shape, a semicircle, an ellipse, and an involute shape.

[0088] One of the embodiments of the present invention is that the outer edge 22 of the middle sheet 2 at the air inlet is provided with a toothed structure 23, please refer to Picture 10 , The turbulent flow at the air inlet passes through the toothed structure 14, and is smoothed. The shape of the tooth structure 23 may be one of rectangular, V-shaped, semicircular, elliptical and involute shape, but the shape of the tooth structure of the present invention is not limited to this. The number of tooth structures is at least one.

[0089] Please refer to Picture 11

[0092] Example three

[0093] A moving impeller includes an upper piece, a middle piece and a lower piece, and a toothed structure is provided on the outer edge of the lower piece at the wind outlet.

[0094] The number of tooth-shaped structures is three or more, and the shape of the tooth-shaped structures can be one of rectangular, V-shaped, semi-circular, elliptical, and involute.

[0095] Please refer to Figure 13 The lower piece structure of the moving impeller provided in this embodiment is shown in the figure, and the outer edge 31 of the lower piece 3 at the wind outlet is provided with a toothed structure 32. In this embodiment, at least one of the outer edge of the top piece at the wind outlet, the outer edge of the middle piece at the wind inlet, and the outer edge of the middle piece at the wind outlet may also be provided with a toothed structure. For the tooth-shaped structures at different positions, the preferred embodiment is that the tooth-shaped structures have the
