The machine body 21 includes a mount 211 disposed thereon, and the rod 1 is mounted on the mount 211 to achieve a pivotal connection with the cleaning head 2 .

As shown in Figure 4, the dirt collection box 23 is provided with the avoidance cavity 231 of the avoidance mounting seat 211, so that the dirt collection box 23 is arranged as a left and right distributed structure, and the left and right sides have respectively a left side dirt collection port 232 and a right side collection port. Dirty mouth 233.

Those skilled in the art can understand that the user controls the forward and backward movement of the cleaning head 2 by holding the handle 1, and the cleaning head 2 drives the cleaning roller 22 to repeatedly drag and rub on the working surface, thereby realizing the cleaning of the working surface. The front and rear sides of the body 21 are respectively provided with a cleaning roller 22. The cleaning roller 22 arranged on the front side of the body 21 is a scrubbing roller, and the cleaning roller 22 arranged on the rear side of the body 21 is a mopping roller. It is also equipped with a spraying member that provides cleaning liquid for the scrubbing roller, and the spraying member provides cleaning liquid for the scrubbing roller to keep the scrubbing roller wet, which is conducive to wet mopping the working surface. The mopping roller should be kept as dry as possible to enhance the absorption effect of the mopping roller on the working surface. Hereinafter, unless otherwise specified, the cleaning roller 22 refers to the mopping roller arranged on the rear side of the machine body 21 .

As shown in FIGS. 5 and 6 , the surface cleaning device further includes a scraping member 25, and the scraping member 25 includes a first scraping member 251 arranged on the top cover 24 and a second scraping member arranged on the top of the mount 211. 252, wherein the second scraping member 252 and the first scraping member 251 are sequentially arranged along the rotation direction of the cleaning roller. As shown in FIG. 8 , the cleaning roller 22 rotates clockwise, so in the clockwise direction, the cleaning roller 22 first contacts the second scraping member 252 and then contacts the first scraping member 251 .

Continuing to refer to Fig. 5 and Fig. 6, when the dirt collection box 23, the top cover 24 and the cleaning roller 22 are in the state installed on the body 21, the first scraping member 251 includes the left side dirt collection port 232 of the dirt collection box 23 The corresponding left scraping member 2511 and the right scraping member 2512 correspond to the right dirt collecting port 233 of the dirt collecting box 23 . In the horizontal direction, the second scraping member 252 is located between the left scraping member 2511 and the right scraping member 2512 .

As shown in FIG. 7 , the cleaning roller 22 has a first cleaning portion 221 corresponding to the dirt collecting opening of the dirt collecting box 23 and a second cleaning portion 222 not corresponding to the dirt collecting opening of the dirt collecting box 23 . When the cleaning roller 22 rotates on the body 21, the first cleaning portion 221 of the cleaning roller 22 contacts the left scraping member 2511 and the right scraping member 2512 of the first scraping member 251, so that the left scraping member 2511 and the right side scraping member 2512 can scrape the first cleaning part 221 . Wherein, the sewage scraped off by the left scraping member 2511 can flow into the dirt collection box 23 through the left sewage collecting port 232 , and the sewage scraped off by the right scraping component 2512 can pass through the right sewage collecting port 233 Into the dirt collection box 23.

Wherein, the sewage squeezed by the second scraping member 252 can diffuse along the left and right sides of the second scraping member 252 and fall into the scraping range of the left scraping member 2511 and the right scraping member 2512 respectively. Within, the sewage content of the first cleaning part 221 of the cleaning roller 22 increases. Then as the cleaning roller 22 continues to rotate, the left scraping member 2511 and the right scraping member 2512 will scrape the sewage on the first cleaning part 221, which is conducive to directly extruding the sewage and bringing the sewage into the into the sewage collection port.

Continuing to refer to FIG. 7 , in the horizontal direction, the distance between the rightmost end of the left scraping member 2511 and the leftmost end of the right scraping member 2512 is less than or equal to the length of the second scraping member 252, so that the second There is an overlapping portion between the scraping member 252 and the first scraping member 251 to avoid the situation that the sewage diffused by the second scraping member 252 cannot completely fall into the scraping area of the first scraping member 251 . Further, the leftmost end of the left scraping member 2511 and the rightmost end of the right scraping member 2512 are located outside the axial end of the cleaning roller 22, so that the most ends of the cleaning roller 22 can also be cleaned by the scraping member 25, A residue of dirty water on the cleaning roller 22 is avoided.

As shown in FIG. 4 , FIG. 7 and FIG. 8 , the mounting seat 211 has an arcuate surface 2111 that is in sliding contact with the cleaning roller 22 , and the second scraping member 252 is disposed on the top of the arcuate surface 2111 . Those skilled in the art can understand that, through the above arrangement, when the cleaning roller 22 rotates counterclockwise, the sewage in the middle of the cleaning roller 22 can first contact the second scraping member 252 and be wiped by the second scraping member 252. 252 diffuses to the left and right ends, then is collected by the left scraping member 2511 and the right scraping member 2512 and merged into the dirt collection box 23, so as to avoid the left scraping member 2511 and the right scraping member 2512 being cleaned first On both sides, the second scraping member 252 cleans up the middle so that the diffused sewage cannot be collected.

Referring to FIG. 4 and FIG. 9 , the dirt collection box 23 further includes a flow guide portion 234 , and the flow guide portion 234 extends outward from the edge of the dirt collection box 23 until the flow guide portion 234 is located at the bottom side of the dirt scraping member 25 .

Those skilled in the art can understand that, by setting the guide part 234 on the dirt collection box 23, the sewage scraped off by the scraping member 25 can fall on the guide part 234 and be guided by the guide part 234 Flowing into the dirt collection box 23 can prevent the sewage from directly falling on the machine body 21 or the cleaning roller 22 to cause secondary pollution.

It should be noted that the cleaning device of the present utility model can also clean up other dirt, such as debris or hair;

The working principle of the cleaning device will be briefly described below with reference to FIGS. 1 to 9 .

When the body 21 , the cleaning roller 22 , the dirt collection box 23 and the top plate are installed on the cleaning head 2 , the cleaning roller 22 starts to rotate counterclockwise and wipes the ground. The cleaning roller 22 contaminated with sewage continues to rotate until the second cleaning part 222 at the middle position of the cleaning roller 22 collides with the second cleaning member 252 on the top of the mounting seat 211 of the body 21, and the second cleaning part 252 is against the second cleaning part. 222 for scraping, and spread the scraped sewage along the left and right sides of the second scraping member 252 . Then the cleaning roller 22 continues to rotate until the first cleaning part 221 of the cleaning roller 22 is in contact with the left side scraping member 2511 and the right side scraping member 2512 of the first scraping member 251 respectively, and the left side scraping member 2511 and the right side are in contact with each other. The side scraping member 2512 scrapes the first cleaning part 221 points, at the same time, the left scraping member 2511 and the right scraping member 2512 will also clean the sewage diffused from the second scraping member 252 scratch. The sewage scraped off by the left scraping member 2511 and the right scraping member 2512 falls on the flow guide part 234 of the dirt collection box 23, and then is guided by the flow guide part 234, so that the sewage passes through the left sewage collection port respectively. 232 and the right side dirt collecting port 233 merge in the dirt collecting box 23.
