Problems solved by technology

[0002] The air outlet noise reduction of traditional vacuum cleaners is achieved by increasing the tortuousness of the air duct, that is, the labyrinth of the air duct, so that the energy loss of the sound wave during the propagation process and the placement of porous sound-absorbing materials at the turning of the air duct to absorb sound energy, thereby achieving For the purpose of noise reduction, the main disadvantage of this structure is that the effect of noise reduction and noise reduction is relatively poor

Embodiment

[0013] Embodiment: As shown in Fig. 1, a kind of sound-absorbing device for vacuum cleaner, this device comprises three sound-absorbing baffles (1) installed in the air outlet channel (3), and the sound-absorbing baffles (1) are covered with small holes ( 2), the sound-absorbing partition (1) is perpendicular to the airflow direction in the air outlet channel (3), and the total ventilation area of ​​the small holes (2) of the sound-absorbing partition (1) is less than 0.5 of the cross-sectional area of ​​the air outlet channel (3). times, the diameter of the small hole (2) on the sound-absorbing partition (1) is less than 6 mm, and the thickness of the sound-absorbing partition (1) is greater than 0.5 mm.

[0014] The use of one or more sound-absorbing partitions (1) installed in the air outlet channel (3) can greatly reduce the noise emitted by the vacuum cleaner during use; the sound-absorbing partition (1) of the present invention can be installed separately in the air outle...

Abstract

The invention discloses a silencing device for a dust collector. Noise generated when the dust collector is used can be greatly reduced through the device.

Description

technical field [0001] The invention relates to a noise reduction device for a vacuum cleaner. Background technique [0002] The air outlet noise reduction of traditional vacuum cleaners is achieved by increasing the tortuousness of the air duct, that is, the labyrinth of the air duct, so that the energy loss of the sound wave during the propagation process and the placement of porous sound-absorbing materials at the turning of the air duct to absorb sound energy, thereby achieving For the purpose of noise reduction, the main disadvantage of this structure is that the effect of noise reduction and noise reduction is relatively poor. Contents of the invention [0003] The object of the present invention is to provide a noise reduction device for a vacuum cleaner, which can greatly reduce the noise emitted by the vacuum cleaner during use by using one or more noise reduction partitions installed in the air outlet channel. [0004] The technical solution of the present inven...
