As people's requirements for the quality of their home environment increase, the noise problem of water suction vacuum cleaners (cordless floor scrubbers) has attracted increasing attention. Effective noise control can not only improve user experience, but also expand its usage scenarios.
First, optimizing motor design is key. Using a high-quality brushless DC motor, its operation is more stable. Compared with traditional brush motors, it can significantly reduce the mechanical noise and electromagnetic noise caused by motor rotation. At the same time, the structure of the motor is optimized and shock-absorbing devices such as rubber pads and springs are added to reduce the resonance between the motor and the fuselage during operation, thereby reducing noise transmission.
In terms of air duct design, the shape and size of the air duct should be reasonably planned to make the air flow more smoothly in the air duct and reduce the noise caused by turbulence. The curve design with a large curvature radius is used to avoid the sharp turn of the air flow to form eddy currents and cause noise. In addition, sound-absorbing materials, such as sound-absorbing cotton, foam materials, etc., are added to the inner wall of the air duct to absorb the noise generated when the airflow passes through, further reducing the outward transmission of air duct noise.
For the roller brush part of the floor washing machine, soft bristle materials with good sound-absorbing properties are selected to not only ensure the cleaning effect, but also reduce the noise caused by the friction between the high-speed rotation of the roller brush and the ground. At the same time, the installation structure of the roller brush is optimized to ensure that its connection with the motor is tight and stable to avoid additional noise caused by the shaking of the roller brush.
Sealing performance is also an important factor affecting noise. Strengthen the sealing between various parts of the floor washing machine to prevent dust and air leakage from causing noise. For example, high-quality sealing strips are used at the connection between the water tank and the fuselage and the seal of the dust box to reduce whistling and other noise caused by air leakage.
In addition, through intelligent control technology, the motor power and speed are automatically adjusted according to different cleaning tasks to avoid unnecessary noise caused by high-speed motor operation during low-load cleaning. In the design of the shell of the floor washing machine, materials with good sound-absorbing effects are used, such as a double-layer plastic shell with sound-absorbing materials filled in the middle to prevent internal noise from spreading outward.
The noise control of water suction vacuum cleaner (cordless floor scrubber) requires the comprehensive use of mute technology from multiple aspects such as motors, air ducts, roller brushes, seals, intelligent controls, and casings. Through optimized design and material selection, the operating noise can be effectively reduced, and the operation noise can be effectively reduced. Users create a quieter and more comfortable cleaning environment, improving the market competitiveness of products and user satisfaction.
