Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a double-roller brush dust collector with high cleaning efficiency. BACKGROUND

[0002] With the continuous and rapid development of national GDP, the continuous growth of consumer income, especially the rapid growth of income level of residents in large and medium-sized cities, the living conditions of residents are constantly improving. Duplex housing and large-area housing are becoming more and more common, and the demand for dust collectors by residents is also increasing.

[0003] Most of the current market dust collectors adopt single roller brush design, which can meet the basic cleaning needs, but the cleaning effect is limited when facing different types of dirt and floor materials. In order to improve the cleaning efficiency, the power of the dust collector is usually increased or the suction structure is improved, but these methods often accompany the increase of energy consumption and the increase of noise.

[0004] Therefore, in order to solve the above problems, double-roller brush dust collectors appear on the market, mainly including a suction device, a suction pipeline and a dust collecting floor brush with two roller brushes. The suction device formed by the motor and the fan is arranged in the dust collector body; the suction pipeline includes a suction head, a dust collecting rigid pipe and a dust collecting hose, the suction head has a downward opening air inlet, and the air inlet is communicated with the air inlet of the fan in the dust collector body through the dust collecting rigid pipe and the dust collecting hose; the two roller brushes are usually arranged side by side along the forward direction of the dust collector and located near the air inlet below. The two roller brushes in the double-roller brush dust collector are usually arranged side by side along the forward direction of the dust collector and located near the air inlet below. When the dust collector performs cleaning operation, the two roller brushes will gather dust and foreign matter on the ground to the air inlet, and then the dust and foreign matter will enter the dust bin in the dust collector body along the suction pipeline under the action of air flow, completing the ground cleaning.

[0005] The rotation direction of the roller brush opposite to the front roller brush in the forward direction is usually the same as the rotation direction of the walking wheel of the dust collector. The front roller brush sweeps dust and foreign matter backward, so that the rear roller brush is easily exposed to the dust and foreign matter swept from the front, causing the rear roller brush to be easily entangled with hair and difficult to clean. Not only does this affect the subsequent cleaning efficiency of the dust collector, but also it may even cause the rear roller brush to be stuck, increasing the probability of damage to the motor of the dust collector, thereby reducing the service life of the dust collector.
