Horizontal-type dust collector with damping connecting device

Abstract

The invention discloses a horizontal-type dust collector with a damping connecting device. The horizontal-type dust collector with the damping connecting device comprises a bottom case, a front cover and a rear cover, wherein a dust collecting device and a motor unit are arranged in the bottom case, the front cover and the rear cover are connected above the bottom case, a motor housing bottom wall of the motor unit and the bottom case are fixedly connected through a bolt, a bottom wall bolt connecting part is formed at the connection position of the motor housing, a bottom case bolt connecting part is correspondingly formed on the bottom case, and a damping device with elasticity, a rubber spring, is arranged between the bottom wall bolt connecting part and the bottom case bolt connecting part. The rubber spring is made of rubber materials with good elasticity, the loss when the motor vibration spreads outward is increased, on the condition that a vibration source is unvarying, vibration spreading paths are cut off as much as possible, vibration path transmission losses are increased, outward spreading of vibration is lowered, and therefore vibration noises of the overall machine can be lowered, and the roles of reducing vibration, lowering damage of a machine body, and improving the vibration noises of the overall machine are played.

Description

technical field [0001] The invention belongs to the structure of a horizontal vacuum cleaner, in particular to a horizontal vacuum cleaner in which a shock-absorbing connection device is arranged at the joint between a motor shell and a bottom shell. Background technique [0002] Vacuum cleaner is a cleaning and sanitary electrical device used to remove dust from floors, carpets, walls, furniture, clothing and various gaps. Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body. The suction pipeline includes a suction head and a suction pipe. The air port communicates with the air inlet of the fan inside the body through the telescopic pipe and flexible pipe of the suction pipe. [0003] When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate at a high speed, exhausting the air inside the vacuum cleaner, forming an instantaneous...

Problems solved by technology

[0011] In the prior art, the fixing method of the motor casing and the bottom casing adopts the rigid combination of bolts. When the vacuum cleaner is working, the vibration of the motor is completely transmitted to the bottom casing through this rigid connection structure, and then transmitted to other components through the parts that cooperate with other components. Parts expand the vibration of the whole machine and form a large vibration noise, which not only brings noise pollution to the user, but also easily damages the vacuum cleaner body due to the vibration of the whole machine
