Problems solved by technology

An existing vacuum cleaner includes a housing with an air inlet and an air outlet, a motor installed in the housing, and a dust bag and filter device installed in the housing and in front of the motor. When the motor is running, the air and dust can be sucked into the casing from the air inlet through the dust bag, so that the dust will stay in the casing when it is blocked by the filter device, and the air can be discharged from the exhaust hole after being pushed by the motor. During the operation, the motor inner cover vibrates, and the motor inner cover then drives the motor outer cover that is in contact with it to vibrate, and in the process of vibration transmission, due to the effect of resonance, the vibration transmitted to the motor outer cover and the vacuum cleaner shell is larger. Large, which makes the working noise of the vacuum cleaner very loud. When the user touches the outer surface of the vacuum cleaner with his hands, he will feel "numb hands", which reduces the user experience. Vibration damping devices will be used to dampen them, but the current damping materials have poor vibration damping effects, poor mechanical strength and aging resistance, and short service life. After a period of use, the vibration damping effect plummets, seriously affecting Improve the use effect and service life of the vacuum cleaner

Description

technical field [0001] The invention relates to the technical field of vacuum cleaner equipment, in particular to a vibration damping material for a vacuum cleaner motor. Background technique [0002] Vacuum cleaners are widely used in daily life. The working principle of the vacuum cleaner is: use the motor to drive the blades to rotate, generate negative pressure in the sealed housing, and inhale dust. During the use of the vacuum cleaner, the motor in the motor inner cover rotates at a high speed, and a negative air pressure is generated in the sealed housing to absorb external dust. An existing vacuum cleaner includes a housing with an air inlet and an air outlet, a motor installed in the housing, and a dust bag and filter device installed in the housing and in front of the motor. When the motor is running, the air and dust can be sucked into the casing from the air inlet through the dust bag, so that the dust will stay in the casing when it is blocked by the filter de...
