Detailed Description

In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention.

It should be noted that, in the present invention, unless otherwise explicitly stated or limited, terms such as "mounted," "connected," "fixed," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art. Furthermore, in the present disclosure, unless explicitly stated or limited otherwise, the first feature "on" or "under" the second feature may comprise direct contact of the first and second features, or may comprise contact of the first and second features not directly but through another feature therebetween.

As shown in fig. 1-2, a floor washing machine comprises a machine body, a sewage collecting device arranged on the machine body, a clean water supplying device, a floor brush arranged at the bottom of the machine body, a control device arranged on the machine body, a power supply and a charging device for placing the machine body and charging the power supply, specifically:

the sewage collecting device is connected with the floor brush through the air suction pipe 1 and sucks sewage in the floor brush through negative pressure, as shown in fig. 3, a front end pipe orifice of the air suction pipe 1 is bent and inclined upwards and is connected with a leakage-proof cover 1a capable of containing sewage, specifically, as shown in fig. 17, the leakage-proof cover 1a comprises a pipe orifice part 1b connected with the air suction pipe 1 and a containing cavity 1c arranged around the pipe orifice part 1b, the upper half part of the pipe orifice part 1b is connected with a bottom end pipe orifice of the air suction pipe 1, a gap is arranged between the lower half part of the pipe orifice part and the bottom end pipe orifice of the air suction pipe 1 so that the air suction pipe 1 is communicated with the containing cavity 1c, the rear end of the leakage-proof cover 1a is connected with a rear cover 1d, and the rear cover 1d is detachably connected with the air suction pipe 1.

By connecting the leakage-proof cover 1a to the bottom end nozzle of the air suction pipe 1, when the floor cleaning machine stops and a small amount of sewage in the air suction pipe 1 flows backwards, the sewage can flow along the lower part of the air suction pipe 1 and directly enters the accommodating cavity 1c of the leakage-proof cover 1a (as shown in fig. 18), and can not enter the cleaning roller through the nozzle part 1b of the leakage-proof cover 1a, so that the pollution to the cleaning roller is reduced to a great extent.

Further, leak protection lid 1 a's overall structure is "protruding" font, and the chamber 1c that holds that is located leak protection lid 1a lower part is extended to left and right both sides to the volume that is used for holding sewage is enlarged, when treating next scrubber to open, these sewage can be up siphoned away again.
