Referring to fig. 4, the fixing plate 72 is used to connect with the housing assembly 10 of the floor scrubber so that the roller assembly 70 can be fixed. During the cleaning operation of the floor cleaning machine, the floor cleaning machine moves under the pushing action, at this time, the roller 710 contacts with the ground and rotates along with the movement of the floor cleaning machine, when the ground has hair or animal hair and other foreign matters, due to the arrangement of the annular groove 713 in the roller 710, the contact area of the roller 710 and the ground is greatly reduced, the static friction force of the roller 710 is greatly reduced due to the reduction of the contact area, and the hair and animal hair and other foreign matters are not adsorbed onto the roller, so that the roller is not wound on the roller shaft 712, but are cleaned by the floor cleaning machine during the cleaning process.

In the roller assembly 70 provided in this embodiment, the annular groove 713 is formed on the surface of the roller 710 along the circumferential direction thereof, so that the contact area between the roller 710 and the ground is effectively reduced, and therefore, the foreign matters such as hair and animal hair on the ground are not wound on the surface of the roller 710 or the roller shaft 712, the problem that the roller 710 is difficult to clean and is easy to fail due to hair winding is avoided, the cleaning effect of the floor scrubber is greatly improved, and the user experience is further improved.

The number of the rollers 710 may be set as required, for example, 1, 2, 3 or more, and the specific setting positions thereof may be adjusted according to the number.

In some embodiments, the number of the rollers 710 is 1, correspondingly, the number of the roller accommodating grooves 721 formed on the fixing plate 72 is 1, and the roller accommodating grooves 721 are formed in the middle of the fixing plate 72, so that a user can also perform a good cleaning effect by keeping balance during the operation of the floor washing machine. And since there is only one of the number of the rollers 710, the possibility that foreign materials are entangled to the rollers 710 is reduced.

In some embodiments, referring to fig. 4 and 5, the number of the rollers 710 is 2, correspondingly, the number of the roller accommodating grooves 721 formed on the fixing plate 72 is 2, and the 2 roller accommodating grooves 721 are respectively formed at two ends of the fixing plate 72, so that the two rollers 710 can have a good supporting effect on the floor washing machine, the stability is better, and the user operation process is smoother.

In some embodiments, the number of the rollers 710 is 3, and correspondingly, the number of the roller accommodating grooves 721 formed on the fixing plate 72 is 3, wherein 2 roller accommodating grooves 721 are respectively formed at two ends of the fixing plate 72, and the other roller accommodating groove 721 is formed in the middle of the fixing plate 72. The 3 rollers 710 can have good supporting effect on the floor washing machine, and have better stability and smoother operation process of the user.

In some embodiments, the number of rollers 710 may be more than 3, and correspondingly, the number of roller accommodating grooves 721 formed on the fixing plate 72 is more than 3, and one roller 710 is accommodated in each roller accommodating groove 721. The roller receiving grooves 721 are arranged along the length direction of the fixing plate 72 and perpendicular to the movement direction of the rollers 710, so that the floor scrubber can be well supported during the cleaning process of the floor scrubber.
