Embodiment 1

[0068] Please refer to Figure 4 The upper blade structure of the fixed impeller provided in this embodiment is shown in the figure. A fixed impeller includes a wind guide vane, and the wind guide vane includes an upper blade 11, a lower blade 13 and a base plate 12. The outer edge 111 of the upper blade is provided with a toothed structure, which can be provided with a toothed structure on the outer edge of some upper blades located at the air inlet, or can be provided with a toothed structure on the outer edge of all the upper blades located at the air inlet .

[0069] There is at least one tooth structure, and the shape of the tooth structure can be one of rectangle, V shape, trapezoid and involute shape.

[0070] The outer edge 111 of the air inlet of the upper blade is provided with a toothed structure 13, and the outer edge 12 of the air outlet of the upper blade 11 is not provided with a toothed structure. When the vacuum cleaner is working, air enters from the air inl...

Abstract

The invention discloses a fixed impeller which comprises an air deflector and a substrate, wherein the air deflector is provided with a toothed structure. The invention also discloses a motor which comprises the fixed impeller. The motor has favorable noise reduction effect under the condition of not adding muting cotton or taking other muting measures; and meanwhile, the air properties of the motor are enhanced.

Description

technical field [0001] The invention relates to a fixed impeller and a motor using the fixed 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 c...
