structures

21 and 22 being provided at both ends of the shaft 23, respectively; and the brush member 24 is detachably mounted on the shaft. Wherein the brush member 24 comprises: a cylindrical member 241 and at least one brush 242, the cylindrical member 241 being configured to fit over the shaft 23 such that the cylindrical member 241 is coaxial with the shaft 23; the at least one brush 242 extends from the outer surface of the cylindrical member 241 in a direction away from the cylindrical member 241, and the at least one brush 242 extends from one end of the cylindrical member 241 to the other end of the cylindrical member 241.

The shaft 23 is in a long cylindrical shape, the axis of which can be regarded as a rotation axis of the cleaning brush 20, and when the cleaning brush 20 is mounted on the apparatus body, the front brush or rear brush driving system can drive the shaft 23 to rotate, so as to drive the shaft surface brush member 24 to clean. The cylindrical member 241 is also elongated and cylindrical, and has a length substantially equal to the length of the shaft. The tubular member 210 may be a flexible member or a rigid member.

As shown in fig. 3, in some embodiments, the number of the brushes 242 is plural, each brush 242 has a V-shaped structure on the outer surface of the cylindrical member 241, the plurality of brushes 242 are uniformly distributed along the circumferential direction of the cylindrical member, and the tips of the V-shaped structures of the plurality of brushes have the same direction in the circumferential direction of the cylindrical member.

In the practical application process, when the first cleaning brush 25 is installed, the first installation structure 21 of the first cleaning brush 25 can only be installed in one direction with the first installation part 31, and the second installation structure 22 can only be installed in one direction with the second installation part 41; when the second cleaning brush 26 is mounted, the first mounting structure 21 of the second cleaning brush 26 can be mounted only in one direction with the fourth mounting portion 61, and the second mounting structure 22 can be mounted only in one direction with the third mounting portion 51. That is, the installation direction of the second cleaning brush 23 is a direction in which the first cleaning brush 25 is rotated 180 degrees in the horizontal direction. It will be appreciated that the front brush (i.e., the first cleaning brush) need only be rotated 180 degrees to become the rear brush (i.e., the second cleaning brush). The V-shaped structure of the second cleaning brush after installation is opposite to the V-shaped structure of the first cleaning brush, namely the pointed ends of the brush pieces on the two cleaning brushes are opposite to the direction of the circumference of the cylindrical component.

In the rotating process, the blades of the first cleaning brush and the blades of the second cleaning brush are in interference contact state all the time, namely the upper layer of blades are not separated, and the lower layer of blades are in contact; and continuing to rotate, separating the upper layer of blades, forming a diamond-shaped closed air duct in the middle of the contact of the blades at the two ends of the lower layer, and collecting garbage to the middle along with the rotation of the brush member, so that the garbage is sucked into a dust box in the equipment along with the air duct, and the aim of cleaning is fulfilled. Along with the synchronous rotation of the first cleaning brush and the second cleaning brush, the diamond-shaped closed air channel formed by the next layer of blades can be gradually reduced until the current closed cleaning is finished, the next closed cleaning can be started immediately, namely, the diamond-shaped closed air channel is formed between the two ends of the next layer of blades in contact, and the cleaning efficiency is further improved.

In other embodiments, the brush members of the first cleaning brush 25 and the brush members of the second cleaning brush 26 may be different, and may be specifically configured according to the cleaning requirements. Optionally, the first cleaning brush 25 is a brush, the second cleaning brush 26 is a rubber brush, and this combination can meet the cleaning effect of various ground environments, that is, the good cleaning capability of the brush to hair or fine soft fibers is utilized, and the first cleaning brush can be utilized to clean the garbage on soft ground such as carpets; meanwhile, the second cleaning brush can be utilized to clean floors, ceramic tiles and the like by utilizing the good cleaning capability of the rubber brush on the hard floors.
