Problems solved by technology

However, this kind of sealing ring is generally made of soft materials such as silica gel. During the working process of the motor, due to the strong suction at the air inlet of the motor, the U-shaped structure on the side wall where the sealing ring is connected will often be deformed, and the air will flow into the motor. The inside of the air outlet is sunken, resulting in a small air intake area of ​​the motor air inlet and a decrease in air volume, which affects the working efficiency of the vacuum cleaner

Abstract

A suspension noise-reduction motor comprises a motor body, a motor housing, a seal ring and buffering components, wherein the motor housing at least partially contains the motor body, the seal ring is arranged on an air inlet of the motor body in a sleeving mode, and the buffering components are installed between the motor body and the motor housing. Due to the seal ring and the multiple buffering components, the motor body is allowed to move in a three-dimensional space, the seal ring comprises an upper shock absorption piece, a lower shock absorption piece and a connecting side wall which is connected with the upper shock absorption piece and the lower shock absorption piece and clamped on the air inlet of the motor body, an S-shaped bent mechanism is arranged on the upper shock absorption piece, and a press plate matched with a protrusion is arranged on the protrusion of the S-shaped bent mechanism so that the seal ring will not be sucked into the air inlet of the motor body. The motor body is suspended in the motor housing by means of the seal ring and the buffering components, and when the motor moves in any direction by means of an elastic mechanism, the seal ring and shock pads, a motor plastic part makes soft contact with the motor housing to achieve the effect of noise reduction.

Description

technical field [0001] The invention relates to a suspension type noise-reducing motor, which is used in a vacuum cleaner and belongs to the technical field of vacuum cleaner equipment. Background technique [0002] Vacuum cleaners on the market, including upright vacuum cleaners, canister vacuum cleaners, hand-held vacuum cleaners, barrel vacuum cleaners, stick vacuum cleaners, backpack vacuum cleaners, carpet cleaners, bed vacuum cleaners, etc., will generate a lot of noise when users are using them , generally about 80 decibels, the noise of the vacuum cleaner is easy to upset, and it will affect the comfort of the user during use. [0003] At present, most vacuum cleaners are sound-proofed by installing a double-motor cover sound insulation structure of the motor inner cover and the motor outer cover outside the motor, and filling the air duct between the inner and outer cover of the motor to reduce noise energy, so as to achieve better reduction. noise effect. However...
