Abstract

The invention discloses a noise reduction backboard under the motor box of a dust collector, belonging to dust collector motor fan supports. The backboard mainly comprises a dust collection device arranged in a bottom shell and a motor box holding a dust suctioning motor. A perforated plate muffler constituting the bottom shell is arranged under the motor box and has a plurality of silencing holes in a perforated backboard of the bottom shell, and a detachable backboard rear cover integrally holding the plurality of silencing holes is arranged at the bottom face of the bottom shell. With such a design, the perforated plate muffler is set for specific frequency noise to realize silencing, and the backboard rear cover intracavity air flow forms an air flow cushion layer on the inner surface of the backboard rear cover to reduce air flow friction and friction-generated noise.

Description

technical field [0001] The invention relates to a support for a motor fan of a vacuum cleaner, in particular to a noise reduction bottom plate under a motor box of a vacuum cleaner. Background technique [0002] The vacuum cleaner is a cleaning and sanitary appliance used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. [0003] According to the classification of vacuum cleaners, they can be divided into vertical vacuum cleaners, horizontal (tank) vacuum cleaners and portable vacuum cleaners. [0004] The structure of the vacuum cleaner generally includes the vacuum cleaner motor that generates suction after the power is introduced, the suction nozzle that forms the air path system, the vacuum tube, the vacuum hose, the dust collection part that separates and accumulates dust, etc. [0005] The body of a horizontal vacuum cleaner generally includes parts such as a front cover, a rear cover and a bottom case. There is a hose connector on the...
