Problems solved by technology

[0003] However, since the general vacuum cleaner does not have a special exhaust channel to reduce the flow speed of the air when it is discharged, the air is directly discharged from the exhaust hole after being pushed by the motor, so the air often produces high-speed disturbance when it is discharged. In addition, since the housing is not equipped with a structure that can absorb noise in the space through which the air flows, the air will also generate high-speed disturbance noise when it flows through the irregular structural surface in the housing

Abstract

The present invention relates to a low-noise air discharging device for a dust collector. The collector comprises the following components: an inner housing, which is internally provided with a receiving chamber for accommodating a dust collector motor; an outer housing, wherein a partition plate is disposed between the outer housing and the inner housing; wherein an inner housing side wall, an outer housing side wall and the partition plate are all provided with air discharging holes; an inner wall of the outer housing, the surface of the inner housing and the surface of the partition plate are all provided with sound-absorbing layers. The low-noise air discharging device for the dust collector is provided with a double silencer chamber for double sound absorption, in order to achieve theeffect of silence; at the same time, the air discharging effect is good, and the discharged gas and the heat generated by the motor can be quickly discharged.

Description

technical field [0001] The invention relates to a vacuum cleaner component, in particular to a low-noise vacuum cleaner exhaust device. Background technique [0002] The working principle of the vacuum cleaner is to use the motor to drive the blades to run at high speed, generate air negative pressure in the sealed shell, and absorb the external dust. Existing vacuum cleaners generally include a housing with an air inlet and an air outlet, a motor installed in the housing, and a dust bag and filter paper installed in the housing and in front of the motor. When the motor is running, the air can be connected to the dust to be sucked into the casing from the air inlet through the dust bag, so that the dust will be blocked by the dust bag and stay in the casing, and the purified air will be discharged from the exhaust hole after being pushed by the motor. [0003] However, because the general vacuum cleaner does not have a special exhaust channel to reduce the flow speed of the...
