Description

Technical Field

[0001] This utility model relates to the technical field of vacuum cleaners, specifically to a noise reduction structure for vacuum cleaners. Background Technology

[0002] A vacuum cleaner is a cleaning device that uses an electric motor to drive blades to rotate at high speed, creating negative air pressure inside a sealed casing, thereby sucking in dust and debris. The working principle of a vacuum cleaner is that the electric motor drives the fan impeller to rotate at high speed, generating extremely strong suction and pressure. Air is expelled at high speed under the action of suction and pressure, while the air in the suction part at the front of the fan continuously replenishes the air in the fan, forming a negative pressure difference. Under the action of this pressure difference, the dust-containing air is sucked into the vacuum cleaner.

[0003] Common vacuum cleaners typically lack noise reduction structures during use, resulting in significant noise that propagates directly into the environment, causing noise pollution. This not only affects the user's hearing and mental health but may also disturb neighbors or family members, negatively impacting the user experience. Therefore, we propose a noise reduction structure for vacuum cleaners. Utility Model Content

The inner wall of the inner soundproof frame contains sound-absorbing cotton, and the inner wall of the outer soundproof frame contains a perforated sound-absorbing panel, which can block sound transmission, reduce noise transmission, and also has a certain sound absorption capacity, absorbing some sound waves and reducing echoes and reverberation. The limiting vibration damping plate inside the vibration control base acts as a limit. The vibration damping damper and vibration damping elastic component, together with the inner buffer pad, provide a certain degree of cushioning and vibration reduction, offering some protection for the vacuum cleaner inside the outer soundproof frame. Through this vibration damping and noise reduction mechanism, the noise generated by the vacuum cleaner during operation can be effectively reduced, making the environment quieter.
