Problems solved by technology

[0003] However, for dry / wet dual-purpose vacuum cleaners or steam vacuum cleaners, in the process of sucking the liquid on the surface to be cleaned, once the power of the main machine is turned off, the liquid drawn into the dust suction channel cannot be vacuumed due to the reduced suction force of the vacuum source. Continue to pump into the recovery bucket in the vacuum cleaner, causing the liquid in the dust suction channel to flow back, and the backflow liquid cannot be recycled into the recovery bucket again

Abstract

The invention discloses a ground brush device of dust collector, which comprises the following parts: ground brush bulk with absorbent hole, pipe connector on the ground brush bulk, adsorbent channel in the ground brush bulk, water accumulation box in the bulk to contain reflux water of adsorbent channel, water accumulation channel to transmit liquid in the water accumulation box into adsorbent channel, wherein the pipe connector connects adsorbent hole through adsorbent channel; when the motor is closed, the reflux water in the adsorbent channel flows in the water accumulation channel; when the motor is started again, which liquid in the water accumulation box is transmitted into adsorbent channel along water channel, which enters into recycling barrel of dust collector automatically.

Description

technical field [0001] The invention relates to a floor brushing device for a vacuum cleaner, in particular to a floor brushing device for a dry / wet dual-purpose vacuum cleaner or a steam vacuum cleaner. Background technique [0002] In the prior art, the ground brush of a dry / wet dual-purpose vacuum cleaner or a steam vacuum cleaner usually includes a ground brush body and a pipe joint arranged on the ground brush body. The dust suction pipes of the dust outlet are connected to form a dust suction channel, and the floor brush body is generally also provided with a brush and a roller. When in use, the rotation of the roller makes the brush move more conveniently on the surface to be cleaned, and the dust on the surface is brushed up through the contact between the brush and the surface to facilitate dust removal. [0003] However, for dry / wet dual-purpose vacuum cleaners or steam vacuum cleaners, in the process of sucking the liquid on the surface to be cleaned, once the po...
