Referring again to fig. 1 to 3, in some embodiments, the second blade 12 is disposed at the front end of the blade 10, and the cleaning tool 100 further includes a third blade 13 disposed on a side of the blade 10 facing away from the first blade 11, i.e., the third blade 13 is disposed on the second side 1012.

The second blade 12 is disposed at the front end of the blade 10, that is, the second blade 12 is disposed on the blade tip 102 and located on the side of the blade tip 102 away from the blade body 101, and at the same time, the first blade 11 extends from the first side surface 1011 to the blade tip 102, so that the first blade 11 can be connected to the second blade 12, and there is no gap between the first blade 11 and the second blade 12, which is convenient for use. The third blade 13 may have the same structure as the first blade 11 or the second blade 12, or may have a different structure from both the first blade 11 and the second blade 12, so as to further enrich the function of the cleaning tool 100. Similarly, referring to fig. 5 to 7, the cleaning blade 100 also includes a first blade 11, a second blade 12 and a third blade 13. In other embodiments, such as the embodiment shown in fig. 4, the cleaning tool 100 may also comprise only the first and second cutting edges 11, 12.

Since the first blade 11 is disposed on the first side 1011, the second blade 12 is disposed on the blade 102, and the third blade 13 is disposed on the second side 1012, three sides of the blade 10 are respectively provided with the blades, so that the use function and the cleaning efficiency of the cleaning tool are improved.

Referring to fig. 1 to 3 and 5 to 6, the third blade 13 is a beveled blade.

The third blade 13 and the second blade 12 are both bevel blades, and both can be used for removing or scraping a film layer or other impurities on the surface of an object. Since the second blade 12 is disposed on the cutting head 102 and the third blade 13 is disposed on the second side surface 1012, the second blade 12 and the third blade 13 can be connected, that is, there is no gap between the second blade 12 and the third blade 13, and the connection point of the second blade 12 and the third blade 13 forms a tip, which can be used to remove dirt that is difficult to clean. It is understood that the second cutting edge 12 and the third cutting edge 13 may not be connected.

When in use, the first blade 11 of the cleaning tool 100 can be used for cleaning impurities in gaps, the second blade 12 or the third blade 13 can be used for cleaning the surface of an object, and the second blade 12 and the third blade 13 have different directions, so that the cleaning tool can be suitable for different holding modes and different traveling directions to meet the requirements of different cleaning surfaces or different use habits. In addition, because the second blade 12 and the third blade 13 can be used for cleaning the surface of an object, the dirt on the blades does not need to be cleaned frequently, the cleaning frequency of the cleaning tool 100 is reduced, and the cleaning efficiency is improved.

Optionally, the edge length of the third blade 13 is greater than the edge length of the second blade 12.

Specifically, in an embodiment, the second blade 12 and the third blade 13 are both beveled blades, the cutting edge of the second blade 12 extends along the second direction Y, and the cutting edge of the third blade 13 extends along the first direction X, so that the cutting edge length of the third blade 13, that is, the length of the third blade 13 extending along the first direction X, is the length of the second blade 12 extending along the second direction Y.

Because the cutting edge length of the third cutting edge 13 is greater than that of the second cutting edge 12, when the cleaning blade is used, the blade 10 can be pushed to move along the first direction X and the dirt and the film layer on the plane can be removed through the second cutting edge 12, and the resistance in cleaning is small; the third blade 13 is then used to sweep the cleaned dirt and film layer away.
