Low-noise dust collection device

Abstract

Disclosed is a low-noise dust collection device. The problem that an existing dust collection device is large in noise, and gasbags and transmission parts are prone to damage is solved. The low-noise dust collection device comprises a filtering net, corrugate gasbags, a reducing motor and a transmission device, and the filtering net, the corrugate gasbags, the reducing motor and the transmission device are assembled in a shell. The low-noise dust collection device is characterized in that the shell is internally provided with an air-inlet channel and an air-outlet channel, the two corrugate gasbags which are arranged oppositely are fixedly connected through linkage rods, and a base plate which is combined with a shell channel wall is provided with a left reverse-stop air suction valve and a right reverse-stop air exhausting valve; an eccentric flexible transmission device is adopted in a transmission mechanism. A driving wheel disc and a driven wheel disc are mutually attracted through annular permanent magnets, a driving shaft of the reducing motor rotates to make the driving wheel disc and the driven wheel disc rotate synchronously, the two corrugate gasbags achieve alternating air suction and air exhausting, and under the cooperative effect of the reverse-stop air suction valve and the reverse-stop air exhausting valve, continuous dust collection work is achieved. The low-noise dust collection device is compact in overall structure and reasonable in design, it is guaranteed that the low-noise dust collection device safely and reliably runs, the low-noise dust collection device is wide in applicability, the occurrence of resonance is effectively avoided or reduced, the noise is remarkably reduced, and thus a quiet dust collection environment is easily obtained.

Description

technical field [0001] The invention relates to a household vacuum cleaner, in particular to a low-noise vacuum cleaner with a flexible driving device as a power source that imitates the volume change of a manpower push-pull airbag for suction and exhaust to generate negative pressure, and belongs to the technical field of household appliances. Background technique [0002] Most of the current vacuum cleaners use high-speed fans with centrifugal rotating blades. The high-speed rotating blades are used to generate centrifugal airflow, which makes the center of the fan form a vacuum negative pressure, thereby generating suction. The strong friction between the high-speed and high-pressure airflow and the blades makes the blades themselves very noisy. The motors used in conjunction with it are all ultra-high-speed, and there are also large metal vibrations. The transmission to the vacuum cleaner shell resonates, and the noise of the two is multiplied, resulting in particularly ...
