The dust suction opening 210 may penetrate the surface of the side portion. In this way, in the process of cleaning the floor brush, dust and other garbage near the front of the front side portion can be adsorbed through the dust suction opening 210 of the front side portion, and dust and other garbage near the back of the back side portion can be adsorbed through the dust suction opening 210 of the back side portion.

Preferably, the dust suction port 700 may be provided at a substantially middle position of the brush main body 200. In addition, the dust suction openings 210 of the first and

second side portions

2031 and 2032 may be radially distributed with respect to the dust suction opening 700.

The floor brush may further include a dust suction passage 220, wherein the dust suction passage 220 is disposed at the bottom of the floor brush main body 200 and is recessed with respect to the surface of the bottom, and the dust suction passage 220 communicates the dust suction opening 210 with the dust suction port 700, so that the garbage to be cleaned is sucked through the dust suction opening 210, then transferred to the dust suction port 700 through the dust suction passage 220, and discharged into a dust suction pipe communicating with the dust suction port 700 through the dust suction port 700.

Each of the two or more dust suction openings 210 located on the same side corresponds to a respective one of the dust suction channels 220, and adjacent dust suction channels 220 are spaced apart in the vicinity of the position close to the dust suction opening 210 (e.g. may be spaced apart by the bottom of the brush body itself).

The suction passages 220 converge near the suction opening 700, for example, to form a suction passage 220, and finally open into the suction opening 700.

Fig. 12 shows a cross-sectional view C-C of fig. 11. As shown in fig. 12, the dust suction passage 220 far from the dust suction opening 700 has a first distance D1 from the bottom surface of the brush body 200, the dust suction passage 220 near the dust suction opening has a second distance D2 from the bottom surface of the brush body 200, and the first distance D1 is smaller than the second distance D2. The dust suction passage 220 from the dust suction opening 210 to the dust suction opening 700 may be provided in a slope shape, which is inclined downward toward the dust suction opening 700 in the view shown in fig. 12. The dust collection efficiency can be effectively improved through the arrangement.

Also, the width of the dust suction passage 220 near the dust suction opening 210 may be greater than the width of the dust suction passage 220 far from the dust suction opening 210 to improve dust suction efficiency. Wherein, the width of one portion of the dust suction passage 220 may be different, and the width of the other portion of the dust suction passage 220 may be the same. For example, as shown in fig. 11, the widths of the middle two suction passages 220 at the upper and lower sides may be different, and the widths of the suction passages 220 at the two sides may be the same.

In addition, a dust suction channel 220 may be provided on the third side 2033 and the fourth side 2034, wherein the dust suction channel 220 may or may not penetrate through the third side 2033 and the fourth side 2034, or may not penetrate through the third side 2033 and the fourth side 2034. Without penetration, the ends of the dust suction passage 220 are at a distance from the third and

fourth sides

2033, 2034.

The dust suction passages corresponding to the third and

fourth sides

2033 and 2034 may also be the same as the dust suction passages corresponding to the first and second sides, and the width of the dust suction passage 220 near the dust suction opening 210 may be greater than the width of the dust suction passage 220 far from the dust suction opening 210 to improve dust suction efficiency. Wherein, a width of a portion of the dust suction passage 220 may be different, and a width of another portion of the dust suction passage 220 may be the same. The dust suction passage 220 far away from the dust suction opening 700 has a first distance D1 from the bottom surface of the brush body 200, the dust suction passage 220 near the dust suction opening has a second distance D2 from the bottom surface of the brush body 200, and the first distance D1 is smaller than the second distance D2. Wherein, the dust suction passage 220 from the dust suction opening 210 to the dust suction opening 700 may be provided in a slope shape. The suction passages converge near the suction opening 700, for example, to form a suction passage, and finally open into the suction opening 700.

In which the above-described dust suction passage 220 may serve as a dust suction branch passage, and the dust suction passage provided near the dust suction port 700 may serve as a dust suction main passage. For example, as shown in fig. 3, a dust suction main passage 221 may be provided near the dust suction port 700, and dust or the like sucked in by each dust suction opening is guided to the dust suction main passage 221 through the dust suction branch passage, and then enters the dust suction port 700.

According to a further embodiment of the present disclosure, as shown in fig. 9 and 10, the cleaner floor brush further includes a suction port control valve 800, and the suction port control valve 800 can be detachably installed at the bottom and covers the suction port 700 and the suction passage 220 near the suction port 700 so as to increase suction force of the suction port.

In a state where the suction port control valve 800 is installed at the bottom, a surface of the suction port control valve 800 facing the suction port 700 is in the form of a ramp inclined toward the suction port 700 in the direction of the suction passage 220.

Fig. 13 shows a schematic diagram of the suction port control valve 800 (control valve). The suction port control valve 800 includes a first face 810, wherein the first face 810 is a side opposite to a face (a face opposite to the floor) of the suction port control valve 800 shown in fig. 9 and 10. The first surface is formed as a ramp, and is formed to have a thinner thickness near both sides of the suction port control valve 800 and a thicker thickness near the middle of the suction port control valve 800.

When the suction port control valve 800 is mounted, the two side ramps of the suction port control valve 800 cooperate with the suction port 700 and the suction passage 220 near the suction port 700 to form two side passages, and the two side ramps of the suction port control valve 800 form a cavity with the suction port 700 and the suction passage 220 near the suction port. The size of the suction port can be changed by providing the suction port control valve 800. For example, the height of the suction channel, and thus the size of the suction opening, can be varied by setting the channel ramp.

The suction port control valve 800 may include a release button 820, and a compression spring may be disposed at a tail portion of the release button 820, and one end of the compression spring may abut against the release button 820, and the other end thereof may abut against a sidewall provided in the suction port control valve 800. The head of the release button 820 may be protruded and the protrusion may be inserted into a recess provided on the brush body 200, so that the suction port control valve 800 can be mounted to the brush body 200. In addition, according to the direction shown in fig. 13, a fixing protrusion (not shown) may be provided, which may be fixedly provided on the wall of the suction port control valve 800 or integrally formed, and may be inserted into a corresponding recess provided on the main body 200 of the floor brush. In addition, the fixing protrusion may be in the form of a release button 820, that is, the installation structure of both sides of the suction port control valve 800 is the same.

The direction of the airflow can be changed by installing the dust suction port control valve 800 on the dust suction port 700, the dust suction efficiency can be improved by a cavity formed by the ramp of the dust suction port control valve 800 and the dust suction port, and the inlet of the formed airflow channel is smaller than the dust suction port after the dust suction port control valve 800 is installed.

When the garbage to be cleaned is larger than the inlet of the dust suction channel, the dust suction port control valve 800 can be taken off, so that the large garbage can be cleaned.

In addition, according to the floor brush of the present disclosure, the suction port control valve 800 and the floor brush body 200 may further include a sealing strip 900, the sealing strip 900 being disposed at least at a position between the two intake inlets so as to isolate the airflows of the two intake inlets from each other by the contact of the sealing strip 900 with the floor. The lengthwise direction of the weather strip 900 is substantially parallel or parallel to the lengthwise direction of the intake inlet. The number of the seal strips 900 is more than two, one of the seal strips is arranged near one air inlet, and the other seal strip is arranged near the other air inlet. Further, two or more weather strips may be provided between the two weather strips, and the like. The sealing strip may be in the form of a pile strip.

Specifically, a first wool top (wool top) 910 may be provided on the suction port control valve, and a second wool top (wool top) 920 may be provided at the bottom of the floor brush main body. The first and second tops are configured as long tops, for example, the second top 920 is located at both sides of the first top 910 for each long top, and each row of the first and second tops is configured as one long top, although two long tops are illustrated in fig. 10, one or more than three long tops may be included.

In the present disclosure, by providing a sealing strip (for example, two strips of wool) to be fitted to the air inlet, sealing is performed at the rear side of each air inlet, forming two independent dust suction passages and forming a vacuum chamber, thereby improving cleaning efficiency, and also, since two effective dust suction passages are formed, it is possible to make the cleaning direction wider. The control valve can shield the dust suction port, so that the suction force of the two dust suction channels can be increased.

According to a further embodiment of the present disclosure, there is also provided a vacuum cleaner, wherein the vacuum cleaner may comprise a floor brush as described above.
