| description | The utility model provides a noise reduction assembly and a suction device, which comprises a first box body, a driving device and a shielding piece, and is characterized in that the first box body comprises at least one first hole and at least one first groove body communicated with the first hole; the driving device is arranged in the first hole and is fixed on the first box body; the shielding piece is arranged on the first box body and is combined with the first groove body to form a first air channel, and the first air channel is used for discharging air in the first box body. The shielding piece is arranged to be combined with the first groove body to form the first air channel, so that heat generated in the first box body due to work of the driving device is discharged, noise generated when the driving device works can be reduced, and the effect is good; the first air duct and the second air duct are arranged to jointly dissipate heat of the driving device, heat dissipation is achieved through the doub |
