According to the needs, the cleaning appliance is also provided with an eccentric roller 7 connected with the bottom of the cleaning head main body 1, the roller is of an eccentric structure, when cleaning, the acting force between the eccentric roller and the cleaning surface is changed under the action of the eccentric roller, when the cleaning head main body 1 is closest to the cleaning water, the gravity action of the cleaning head main body 1 is utilized to generate larger friction force, and the garbage which is not easy to clean can be better cleaned. Simultaneously, the garbage removing device is matched with the shovel strip structure, and the garbage stuck on the cleaning surface can be removed by utilizing the gravity of the eccentric roller during working.
In order to avoid sucking the electric wire and cable in the cleaning process, the anti-collision mechanism further comprises a wire protection stop block 6 arranged at the front end of the protective cover or the baffle, the wire protection stop block 6 is flush with the cleaning surface when being cleaned with the roller 4, and due to the existence of the wire protection stop block, the electric wire and cable in the advancing direction of the cleaning appliance can be stopped during use, and meanwhile, the cleaning of the cleaning surface is not influenced. The number of the wire protecting stop blocks is three, and the wire protecting stop blocks are respectively distributed at the front end of the roller at intervals. This avoids the dirt on the cleaning surface being trapped in the cleaning implement, thereby affecting the cleaning effect.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: it is to be understood that modifications may be made to the above-described arrangements in the embodiments or equivalents may be substituted for some of the features of the embodiments without departing from the spirit or scope of the present invention.
