Abstract
The utility model relates to the technical field of cleaning discloses a surface cleaning device and system of noise reduction. About the surface cleaning device of noise reduction, host computer is equipped with fan assembly and air duct, and the bottom is equipped with the cleaning turntable assembly of connecting air duct, fan assembly is equipped with in the top and is used for generating airflow in the air duct to form negative pressure to make the cleaning turntable assembly adsorb in the surface to be cleaned, in the air duct, the air inlet section is equipped with in the air inlet side of fan assembly, and the air inlet of air inlet section is equipped with in the cleaning turntable assembly, the air outlet section is equipped with in the air outlet side of fan assembly, and the air outlet section has the first part opposite with the airflow direction in the air inlet section. The utility model discloses the technical scheme, the airflow direction of air outlet section and air inlet section is opposite, can form the air duct to the downward, changed the propagation direction of sound, has energy loss, and the air resistance of air duct to the downward is big, and the above air inlet section combines the air outlet section and makes the air duct lengthening, all can play the role of noise reduction, the design of above air duct plays the better noise reduction effect, improves the use experience of user.
