Double-duct dust collector floor brush

Abstract

The invention relates to a double-duct dust collector floor brush which comprises a shell and a pipe connector arranged at the rear end of the shell. The shell comprises an upper cover and a lower cover provided with air inlet ducts, the upper cover is fixedly connected with the lower cover, the lower cover is provided with a dust collection port, the pipe connector is provided with a pipe cavity, the dust collection port is communicated with a pipe cavity through the air inlet ducts, the air inlet ducts are two in number and include the first air inlet duct and the second air inlet duct, and the first air inlet duct and the second air inlet duct are arranged on the two sides of the lower cover respectively side by side. The dust collector floor brush is provided with the two air inlet ducts, so that suction force of the ducts is uniform, and dust collection is efficient.

Description

technical field [0001] The invention mainly relates to a floor brush of a vacuum cleaner with double air ducts. Background technique [0002] The floor brush of the vacuum cleaner in the prior art includes a housing composed of an upper cover and a lower cover with an air intake duct, and an elbow arranged at the rear end of the housing. The lumen of the elbow communicates with the air intake duct. There is only one air intake duct in the ground brush of the vacuum cleaner in the technology, and the air intake duct is set in the middle of the ground brush of the vacuum cleaner, so that the ground brush of the vacuum cleaner with a single air intake air duct has no suction force for the entire suction port. On average, the suction force of the middle part of the dust suction port is greater than that of other parts of the dust suction port. During cleaning, the garbage at other positions of the dust suction port is not easy to be sucked into the vacuum cleaner, and the dust c...

Problems solved by technology

[0002] The floor brush of the vacuum cleaner in the prior art includes a housing composed of an upper cover and a lower cover with an air intake duct, and an elbow arranged at the rear end of the housing. The lumen of the elbow communicates with the air intake duct. There is only one air intake duct in the ground brush of the vacuum cleaner in the technology, and the air intake duct is set in the middle of the ground brush of the vacuum cleaner, so that the ground brush of the vacuum cleaner with a single air intake air duct has no suction force for the entire suction port. On average, the suction force of the middle part of the dust suction port is greater than that of other parts of the dust suction port. When cleaning, the garbage at other positions of the dust suction port is not easy to be sucked into the vacuum cleaner, and the dust collection efficiency is low.

Moreover, the ground brush of the single-air duct vacuum cleaner connects the housing and the elbow, and the energy is easy to leak, which further reduces the dust collection efficiency.
