As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 and 2, an embodiment of the present invention provides an air exhaust device 100, which is disposed on an air exhaust device for exhausting air. The air exhausting device may be a vacuum cleaner 200 or an air cleaner, which is suitable for any air exhausting device that needs to be provided with the air exhausting device 100, and is not limited herein.
The technical solution of the present application will be described in detail below by taking the vacuum cleaner 200 as an example. The present embodiment is only for exemplary purposes and does not limit the technical scope of the present application. In addition, the drawings in the embodiments omit unnecessary components to clearly show the technical features of the application.
The vacuum cleaner 200 includes an exhaust device 100, a gas-dust separating device (not shown in the figure) and a power supply 200, the exhaust device 100 includes a housing 10 (see fig. 2) and a gas power mechanism 20 (see fig. 2), the gas-dust separating device is disposed outside the housing 10 for separating gas from dust, the gas power mechanism 20 is disposed in the housing 10 for providing power for airflow flowing in the vacuum cleaner 200, and the power supply 200 is configured for providing electric power for the gas power mechanism 20.
The external air flow firstly enters the air-dust separating device for air-dust separation under the action of the air power mechanism 20, dust formed after the air-dust separation is deposited in the air-dust separating device, and air formed after the air-dust separation enters the air exhaust device 100 and is exhausted to the outside.
The exhaust device 100 further includes a damper 40, and a gas flow chamber (not shown) is defined between the gas actuating unit 20 and the housing 10. The damping piece 40 is arranged between the gas power mechanism 20 and the shell 10, and divides the airflow cavity into a closed cavity 31 isolated from the outside and a communicating cavity 32 communicated with the outside, and the damping piece 40 is provided with an airflow hole 41 communicated between the closed cavity 31 and the communicating cavity 32. The gas power mechanism 20 has a gas inlet end 21 and a gas outlet end 22 which are communicated with each other, the gas inlet end 21 is communicated with the outside, and the gas outlet end 22 is communicated with the closed cavity 31.
Thus, the gas formed after the gas-dust separation device is separated enters from the gas inlet end 21 of the gas power mechanism 20 and is discharged into the closed cavity 31 from the gas outlet end 22, and the gas enters into the communication cavity 32 from the gas flow hole 41 and is discharged to the outside because the closed cavity 31 is isolated from the outside. That is, the exhaust device 100 does not exhaust air from the air outlet end 22 of the pneumatic mechanism 20, but returns air from the air outlet end to a position close to the air inlet end 21 of the pneumatic mechanism 20.
Moreover, since the damping member 40 has the airflow hole 41, compared with the damping member 40 with a solid structure, the airflow hole 41 can increase the elasticity of the damping member 40 to increase the damping effect, so that the noise transmitted from the gas power mechanism 20 to the outside is small.
The cleaner 200 further comprises a handle 300, the handle 300 being connected to the housing 10 to facilitate the user's handling of the cleaner 200. Specifically, the handle 300 is fitted to an end of the housing 10 remote from the communication chamber 32. When the user operates the vacuum cleaner 200 through the handle 300, since the communicating chamber 32 is disposed away from the handle 300, the vacuum cleaner 200 will be vented from a position away from the human body, and direct blowing to the human body is avoided.
It should be noted that the fact that the handle 300 is mounted on the end of the housing 10 away from the communication chamber 32 means that: the handle 300 may be mounted on the side of the housing 10 remote from the end of the communication chamber 32 or on the side facing away from the handle 300.
The vibration damping member 40 is sleeved between the gas power mechanism 20 and the housing 10 to increase the contact area between the vibration damping member 40 and the gas power mechanism 20 and increase the vibration damping effect. Specifically, the outer peripheral wall of the gas power mechanism 20 is provided with a resisting portion 23 resisting in the flowing direction of the gas flow, and the vibration damping member 40 is in contact with the resisting portion 23 to reduce the movement of the vibration damping member 40 in the gas flow cavity when being impacted by the gas flow.
In one embodiment, the wall of the closed chamber 31 at the end away from the airflow hole 41 forms an arc-shaped portion 11 opening toward the airflow hole 41, and the arc-shaped portion 11 is disposed opposite to the airflow hole 41. The provision of the arc portion 11 facilitates the direction of the wind flowing out from the outlet end 22 of the gas actuating unit 20 into the airflow hole 41.
Specifically, the housing 10 includes a first half-shell 14 and a second half-shell 15, which are separately disposed, the first half-shell 14 and the second half-shell 15 are butted to form the housing 10, and the arc portion 31 is disposed on the second half-shell 15. The first half shell 14 and the second half shell 15 of the housing 10 are formed as separate bodies, which facilitates the assembly of the pneumatic mechanism 20 and the damping member 40.
Further, the airflow hole 41 includes a plurality of holes provided in the circumferential direction of the damper 40 so as to facilitate the airflow entering the communication chamber 32 from the closing chamber 31 to be discharged to the outside.
Specifically, each airflow hole 41 includes a middle section 411, and an air inlet section 412 and an air outlet section 413 respectively located at two ends of the middle section 411, wherein a sectional area of an end of the air inlet section 412 connected to the middle section 411 to an end thereof far away from the middle section 411 is gradually increased, and/or a sectional area of an end of the air outlet section 413 connected to the middle section 411 to an end thereof far away from the middle section 411 is gradually increased. That is, the air inlet section 412 may be set to be tapered, and at this time, the air inlet area of the air inlet section 412 is increased, so that the airflow smoothly enters the airflow hole 41 to reduce wind resistance and noise, and the same is true for setting the air outlet section 413 to be tapered.
The exhaust device 100 further comprises an air inlet pipe 50, and the air inlet pipe 50 is communicated between the air-dust separating device and the air inlet end of the gas power mechanism 20, so that the air flowing out of the air-dust separating device can enter the gas power mechanism 20.
