Correspondingly, the right end of the roller brush cover 130 is provided with an extension part 137 which extends backwards and is matched with the avoidance part 118, and the rear wall of the extension part 137 is provided with a buckle 138 which is matched with the clamping groove 119. When the roller brush cover 130 is buckled and installed on the ground brush main body 110, the extending part 137 is matched with the avoiding part 118, the buckle 138 is inserted into the clamping groove 119, and the rear part of the right end of the roller brush cover 130 is subjected to downward acting force through the matching of the buckle 138 and the clamping groove 119, so that the front part of the right end of the roller brush cover 130 is subjected to upward moment action, and the situation that the front part of the right end of the roller brush cover 130 sinks due to suspension arrangement and interferes with the rotating roller brush 120 is avoided.

It will be appreciated that the placement of the secondary catch 152 and catch 138 may be interchanged.

Other structures of the third embodiment are the same as those of the first embodiment, and will not be described in detail here.

It is understood that the third embodiment may be combined with the second embodiment, and the magnetic attraction structure may be disposed only between the avoiding portion 118 and the extending portion 137.

Example IV

Referring to fig. 10 and 11, in this embodiment, in order to facilitate the user to observe the condition of the surface to be cleaned, a light emitting assembly 170 with a light source 171 is disposed in the brush main body 110, the light emitting assembly 170 is located at the rear side of the sink base 116, the roller brush cover 130 is provided with a light guide plate 180 extending from the rear to the front for guiding the light of the light emitting assembly 170 forward, the light guide plate 180 is clamped between the upper cover plate 131 and the lower cover plate 132, and the latch assembly 150 is disposed between the upper cover plate 131 and the light guide plate 180. Specifically, the light emitting assembly 170 further includes a light plate 173 and a light converging member 172, the light source 171 is disposed on the front side of the light plate 173, the light converging member 172 is disposed opposite to the light plate 173, and the light emitting surface of the light converging member 172 is exposed from the rear wall of the sinking platform 116. When the roller brush cover 130 is fastened to the floor brush main body 110, the rear end surface of the light guide plate 180 faces the light emitting surface of the light converging member 172, and the light emitted from the light source 171 is converged by the light converging member 172 and then is incident on the light guide plate 180, and then is emitted forward along the light guide plate 180 and irradiated on the surface to be cleaned.

Other structures of the fourth embodiment are the same as those of the first embodiment, and will not be described in detail here.

It will be appreciated that the fourth embodiment may be combined with the second embodiment.

It will be appreciated that the fourth embodiment may be combined with the third embodiment.

In addition to the above preferred embodiments, the present utility model has other embodiments, and various changes and modifications may be made by those skilled in the art without departing from the spirit of the utility model, which shall fall within the scope of the utility model as defined in the appended claims.
