Description

Dust collector floor brush

Technical Field

A floor brush of a dust collector is used for cleaning the ground and belongs to the technical field of dust collector manufacturing.

Background

The dust collector mainly utilizes negative pressure to absorb garbage and dust on the ground, and mainly comprises two parts, wherein one part is a dust collection device generating negative pressure, the other part is a suction nozzle (namely a floor brush) in contact with the ground, and the dust collection device is connected with the suction nozzle through a pipeline; sealing strips are arranged on the left side, the right side and the rear side of a dust suction opening of a suction nozzle of the existing dust collector, and the three sealing strips are sequentially connected end to end, so that air can enter the dust suction opening from a gap formed between the bottom surface of the front side of the dust suction opening and the lower surface of the suction nozzle during dust suction, the vacuum degree of the dust suction opening can be ensured, and the cleaning effect is improved; however, our floor is not a whole horizontal plane, for example, the floor in a household has gaps at the joints between floor tiles, and the floor in a square or public place has shallow drainage ditches, so when using a vacuum cleaner for cleaning, a situation that a suction nozzle (a floor brush) crosses over the gaps or the drainage ditches (as shown in fig. 1) is inevitably encountered, which affects the vacuum degree at the suction opening and results in a reduction of the cleaning effect; we cannot rely on increasing the power of the suction fan in the cleaner to increase the vacuum, for reasons such as the publication: CN 104138238B, name: the cleaning robot and the floor processing device are described in the invention patents: the cleaning robot is generally powered by a rechargeable battery, and if the dust suction vacuum degree is increased by increasing the dust suction power on one side, the working time of the dust collector is shortened, so that a cleaning device capable of increasing the dust suction vacuum degree without increasing the dust suction power needs to be researched.

Detailed Description

As shown in fig. 1-10, a dust collector floor brush comprises a housing 2 with a dust collection port 1 on the bottom wall, a connection pipe 3 arranged on the top wall of the housing 2, and a round brush 4 located in the housing 2 and matched with the dust collection port 1, wherein a C-shaped sealing device 5 surrounding the dust collection port 1 is arranged on the outer bottom wall of the housing 2, a C-shaped groove 8 surrounding the dust collection port 1 is arranged on the outer bottom wall of the housing 2, the side wall of the C-shaped sealing device 5 is slidably connected with the side wall of the C-shaped groove 8, the C-shaped sealing device 5 is composed of a plurality of sealing units 5-1, two adjacent sealing units 5-1 are slidably and sealingly connected with each other, and the direction of relative sliding between the two adjacent sealing units 5-1 is perpendicular to the outer bottom wall of the housing 2.

In the present invention, in use, the connecting pipe 3 is used to connect the housing 2 with the vacuum cleaner, the suction opening 1 of the housing 2 is aligned with the ground, the vacuum cleaner (not shown) is opened, so that a negative pressure system in the vacuum cleaner generates a negative pressure, and at the same time, the switch controlling the rotation of the roller brush 4 is turned on, the roller brush 4 rotates to suck dust and garbage located in an area of the ground surrounded by the C-shaped sealing device 5 into the C-shaped sealing device 5 through the suction opening, and then the garbage and dust on the ground surrounded by the C-shaped sealing device 5 into the vacuum cleaner through the suction opening, when a ground gully (i.e., a gap or a drain as described in the background art) is encountered, since the C-shaped sealing device 5 is composed of a plurality of sealing units 5-1, and the sealing units 5-1 are slidably and sealingly connected to each other, and the sealing units 5-1 are slidably moved in a direction perpendicular to the wall of the housing 2, that is, a gap between the sealing units 5-1 is vertically moved in a direction of the ground surface, so that a gravity acts on the sealing gully (i.e., a gap between the sealing units 5-1) to block the suction opening, and thus the vacuum cleaner, a gravity acts on the lower surface of the dust cleaner, thereby causing a gap, which may cause a gap between the sealing unit 5, which may cause a vacuum cleaner, i.e., a gap, which may occur; when the dust collector is on a flat ground, the upper section of the sealing unit 5-1 extends into the C-shaped groove 8 under the action of gravity of the shell 2 and parts in the shell 2, at the moment, the lower surfaces of all the sealing units 5-1 are in contact with the ground, so that airflow is prevented from entering the C-shaped sealing device 5 from a position between the lower surface of the sealing unit 5-1 and the ground, and after cleaning of an area in a gully on the ground is finished, a user only needs to lift the shell 2 upwards to enable the sealing unit 5-1 extending into the lower gully to leave the gully and then continue cleaning.

In order to adapt to the problem that different vacuum degrees in the shell need to be ensured for different wastes on the ground, for example, paper scraps exist on the ground, when hairs exist, the air flow needs to be larger, and the C-shaped opening of the C-shaped sealing device 5 is larger; when only dust is on the ground, the C-shaped opening of the C-shaped sealing device 5 can be adjusted to be smaller, so that the dust collection speed is improved, preferably: as shown in fig. 6, 8, 9, 2, 3 and 4, the left end and the right end of the blocking piece 6 are slidably connected to the C-shaped sealing device 5, the upper end of the blocking piece 6 is rotatably connected to the outer bottom wall of the housing 2, the rotating shaft of the blocking piece 6 is in transmission connection with the output shaft of the gear motor 7, and the gear motor 7 is fixedly arranged on the housing 2, after the design, the rotating angle (the angle relative to the bottom surface of the housing 2) of the blocking piece 6 is adjusted by the rotation of the output shaft of the gear motor 7, so that the size of the C-shaped opening of the C-shaped sealing device 5 is adjusted to adjust the vacuum degree.

As shown in fig. 5 and 6, in order to allow the sealing unit 5-1 to extend into the gullies when the housing is located above the gullies to ensure a vacuum degree in the C-shaped sealing device 5, the top end of the sealing unit 5-1 is fixedly connected to the bottom wall of the C-shaped groove 8 through the elastic member 9.
