Problems solved by technology

[0002] The exhaust port of the vacuum cleaner in the prior art is generally a grid structure, and its function is only to prevent debris from entering the body of the vacuum cleaner, but has no sound attenuation effect. Therefore, the noise emitted by ordinary vacuum cleaners is relatively large when in use.

[0019] Embodiment one: if figure 1 , figure 2 As shown, a noise reduction device for a vacuum cleaner includes a closed casing (1), the casing (1) is provided with an air inlet end (2) and an air outlet end (3), the air inlet end (2) and the air outlet end (3). The air outlets (3) are respectively located at the front and rear ends of the casing (1), the air inlet direction is the same as the air outlet direction, and a muffler cavity (4) is provided between the air inlet end (2) and the air outlet end (3) , the air inlet end (2) and the air outlet end (3) are provided with an air inlet area (6) and an air outlet area (7) composed of densely distributed pipe-like exhaust holes (5), and the air inlet cross-sectional area and the air outlet cross-sectional area are respectively less than the cross-sectional area of ​​the muffler cavity (4); the air inlet area (6) on the air inlet end (2) is located around the air inlet end (2), and the inner wall of the air inlet end (2) The ...

Embodiment 2

[0020] Embodiment two: if figure 2 As shown, a noise reduction device for a vacuum cleaner includes a closed casing (1), the casing (1) is provided with an air inlet end (2) and an air outlet end (3), the air inlet end (2) and the air outlet end (3). The air outlets (3) are respectively located at the front end and the side end of the housing (1), the air inlet direction and the air outlet direction have an included angle, and a muffler chamber ( 4), the air inlet end (2) and the air outlet end (3) are provided with an air inlet area (6) and an air outlet area (7) composed of densely distributed pipe-like exhaust holes (5), and the air inlet The cross-sectional area and the wind outlet cross-sectional area are respectively smaller than the cross-sectional area of ​​the muffler chamber (4).

Embodiment 3

[0021] Embodiment three: as Figure 4 As shown, a noise reduction device for a vacuum cleaner includes a closed casing (1), the casing (1) is provided with an air inlet end (2) and an air outlet end (3), the air inlet end (2) and the air outlet end (3). The air outlets (3) are respectively located on different sides of the casing (1), the air inlet direction and the air outlet direction have an included angle, and a muffler chamber (4) is provided between the air inlet end (2) and the air outlet end (3) , the air inlet end (2) and the air outlet end (3) are provided with an air inlet area (6) and an air outlet area (7) composed of densely distributed pipe-like exhaust holes (5), and the air inlet cross-sectional area and the cross-sectional area of ​​the air outlet are respectively smaller than the cross-sectional area of ​​the muffler cavity (4).

Abstract

A silencer of cleaner is composed of an enclosed casing with wind inlet and outlet, a silencing cavity between said wind inlet and outlet, and the wind entrance region and exit region consisting of dense tubular exhaust pinhole, and features that the cross-section for wind entrance and exit is less than that of said silencing cavity. Its advantage is high effect on reducing noise.

Description

technical field [0001] The invention relates to a vacuum cleaner. Background technique [0002] The exhaust port of the vacuum cleaner in the prior art is generally a grid structure, and its function is only to prevent debris from entering the body of the vacuum cleaner, but has no noise reduction effect. Therefore, ordinary vacuum cleaners emit relatively large noises when in use. Contents of the invention [0003] The object of the present invention is to provide a noise reduction device for a vacuum cleaner, which integrates various noise reduction structures into one body, and after being installed on the air outlet of the vacuum cleaner, can greatly reduce the noise emitted by the vacuum cleaner during use. [0004] The technical solution of the present invention is: a noise reduction device for a vacuum cleaner, the device includes a closed casing, the casing is provided with an air inlet end and an air outlet end, and a noise reduction chamber is provided between th...
