Embodiment 1

[0079] The utility model relates to a moving impeller, which includes an upper piece, a middle piece and a lower piece, and a tooth-shaped structure is arranged on the outer edge of the upper piece at the wind outlet.

[0080] The number of tooth structures is at least three, and the shape of the tooth structures may be one of rectangle, V shape, semicircle, ellipse and involute shape.

[0081] Please refer to Figure 5 , the structure of the upper piece of the moving impeller provided in this embodiment is shown in the figure, the outer edge 11 of the wind outlet of the upper piece 1 is provided with a toothed structure 13, and the outer edge 12 of the wind inlet of the upper piece 1 is not provided. With a toothed structure, when the vacuum cleaner is working, the moving impeller rotates at a high speed, the air is sucked in from the air inlet, discharged through the suction channel, and is combed smoothly when passing through the toothed structure 13 on the outer edge 11 of...

Embodiment 2

[0086] The utility model relates to a moving impeller, which includes an upper piece, a middle piece and a lower piece, and a tooth-shaped structure is arranged on the outer edge of the middle piece at the wind inlet and / or the wind outlet.

[0087] There is one or more than one tooth structure, and the shape of the tooth structure can be one of rectangle, V shape, semicircle, ellipse and 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 Figure 10 , the turbulent flow at the air inlet passes through the toothed structure 14 and is combed smoothly. The shape of the tooth structure 23 can be one of rectangle, V shape, semicircle, ellipse and involute, but the shape of the tooth structure in the present invention is not limited thereto. The number of toothed structures is at least one.

[0089] Please refer to Figure 11 , is another...

Embodiment 3

[0093] The utility model relates to a moving impeller, which includes an upper piece, a middle piece and a lower piece, and a tooth-shaped structure is arranged on the outer edge of the lower piece at the air outlet.

[0094] The number of tooth structures is three or more, and the shape of the tooth structures can be one of rectangle, V shape, semicircle, ellipse and involute shape.

[0095] Please refer to Figure 13 , The structure of the lower piece 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 outlet of the wind is provided with a toothed structure 32 . Under this embodiment, at least one of the outer edge of the upper sheet at the air outlet, the outer edge of the middle sheet at the air inlet, and the outer edge of the middle sheet at the air outlet can also be provided with a toothed structure. The preferred embodiment of the toothed structures at different positions is that the toothed str...

Abstract

A rotor impeller comprises an upper blade, a middle blade and a lower blade. At least one of the upper blade, the middle blade and the lower blade is provided with a toothed structure. The invention further discloses a motor which comprises the rotor impeller. A good noise reducing effect is achieved under the condition that no noise reducing cotton or other noise reducing measures are added, and meanwhile the air performance of the motor is improved.

Description

technical field [0001] The invention relates to a moving impeller and a motor using the moving impeller, which are used in a vacuum cleaner and belong to the technical field of vacuum cleaner equipment. Background technique [0002] Vacuum cleaners on the market, including upright vacuum cleaners, canister vacuum cleaners, hand-held vacuum cleaners, bucket vacuum cleaners, stick vacuum cleaners, backpack vacuum cleaners, carpet cleaners, bed vacuums, etc., users will generate a lot of noise during use. Noise, the noise of the vacuum cleaner is easy to make people upset, and it will affect the user's comfort during use. [0003] The motor of the vacuum cleaner is always accompanied by noise during the working process, which has a significant adverse effect on the performance of the product and the user experience. Therefore, reducing noise is an important subject that the vacuum cleaner industry has been studying. The motor is the main kinetic energy component in the vacuum...
