Problems solved by technology

However, in the existing noise reduction structure, since the inner cover of the motor closest to the motor is a single-wall structure, it cannot play a further role in sound insulation or noise reduction, and cannot effectively reduce noise energy, so it greatly limits Overall noise reduction effect of the noise reduction structure

Embodiment 1

[0027] Example 1: First combine figure 1 , figure 2 As shown, the vacuum cleaner motor noise reduction structure provided by this embodiment includes a motor inner cover 2 and a motor outer cover 3 surrounding the motor 1, and the motor inner cover 2 is provided with a first air outlet 201 communicating with the motor 1, The motor cover 3 is provided with a second air outlet 301 , and the first air outlet 201 communicates with the second air outlet 301 through the air duct 6 formed inside the motor and between the outer covers 2 and 3 . The air duct 6 is provided with an outer cover sound-absorbing sponge 7 , the second air outlet 301 is filled with an air outlet sponge 8 , and an air outlet seamask 9 is provided outside the second air outlet 301 .

[0028] The motor inner cover 2 described in this embodiment is a double-layer hollow structure in view of its cross section, that is, this motor inner cover 2 has an additional circle of sound-absorbing cavity a on its original ...

Embodiment 2

[0031] Embodiment 2: The difference from Embodiment 1 is that part of the motor inner cover 2 is a double-layer hollow structure. For details, see image 3 , the motor inner cover 2 in this embodiment has three additional sound-absorbing cavities a on its original outer wall, one of which is located at the upper position of the original outer wall of the motor inner cover 2, and the other two are located in the motor inner cover 2. The lower positions on the left and right sides of the original outer wall, and these three sound-absorbing chambers a are all open chambers, and their insides are all filled with inner cover sound-absorbing sponge 4 (not shown in the figure). The rest of this embodiment are the same as embodiment 1.

Embodiment 3

[0032] Embodiment 3: The difference from Embodiment 2 is that a sound-absorbing chamber a above the motor inner cover 2 is further divided into four chambers by three transverse partitions 5, and two chambers at the lower left and right sides of the motor inner cover 2 a, so the motor inner cover 2 of the present embodiment actually adds six silencing chambers a on its original outer wall, specifically see Figure 4 , and each sound-absorbing cavity a is also an open cavity, and the inside is filled with inner cover sound-absorbing sponge 4 (not shown in the figure). The rest of this embodiment are the same as embodiment 2.

Abstract

The invention discloses a noise reduction structure of a motor of a vacuum cleaner, which comprises a motor inner cover and a motor outer cover surrounding the motor. The noise reduction structure is characterized in that the lateral wall of the motor inner cover is provided with at least one sound deadening chamber. Compared with the prior art, because the lateral wall of the motor inner cover is provided with at least one sound deadening chamber which plays a good role in sound insulation and noise elimination, the noise reduction effect of the noise reduction structure of the motor of the vacuum cleaner is greatly enhanced.

Description

technical field [0001] The invention relates to a noise reduction structure for a vacuum cleaner motor. Background technique [0002] At present, the relatively effective noise reduction structure for vacuum cleaner motors is basically the same, that is, the sound insulation structure of the double motor cover with the motor inner cover and the motor outer cover is used to produce sound insulation effects, and sound-absorbing materials (such as Noise-absorbing sponge) to reduce noise energy to achieve better noise reduction effect. However, in the existing noise reduction structure, since the inner cover of the motor closest to the motor is a single-wall structure, it cannot play a further role in sound insulation or noise reduction, and cannot effectively reduce noise energy, so it greatly limits The overall noise reduction effect of the noise reduction structure. Contents of the invention [0003] The object of the present invention is to provide a noise reduction stru...
