In the floor brush of the dust collector provided by the embodiment, the transmission assembly 220 comprises a worm 221, a worm wheel 222 and a turbine shaft 223, the worm 221 is meshed with the worm wheel 222, the worm wheel 222 is sleeved on the turbine shaft 223, the turbine shaft 223 is connected with the cleaning assembly 300, two output shafts 212 rotating in the same direction are arranged on the opposite sides of the driving element 210, and the worm 221 is coaxially connected with the output shafts 212; the second balancing device 120 is located on the worm 221 and/or the turbine shaft 223. That is, the second balancer 120 may be provided on the worm 221, the second balancer 120 may be provided on the turbine shaft 223, or the second balancer 120 may be provided on both the turbine shaft 223 and the worm 221.

Specifically, the worm 221 and the output shaft 212 may be coaxially connected by a coupling or may be coaxially connected by the connecting shaft 190. In order to connect the turbine 222 and the output shaft 212 through the connecting shaft 190, the output shaft 212 may be inserted into the connecting shaft 190, and the turbine 222 may also be inserted into the connecting shaft 190.

The second balancer 120 of the turbine shaft 223 may have the same or different structure from the second balancer 120 of the worm 221. Next, the second balancer 120 of the turbine shaft 223 and the second balancer 120 of the worm 221 have different structures, and the description will be given.

The second balancing device 120 on the worm 221 may be configured as follows: the second balancing device 120 comprises a shock absorbing member 121 and a second supporting component 122 for supporting the shock absorbing member 121, the second supporting component 122 is matched with the outer side wall of the shock absorbing member 121, the shock absorbing member 121 is sleeved on the worm 221, and at least part of the second supporting component 122 is located on the inner wall of the casing 100.

Wherein the second supporting member 122 may have a second supporting surface 1221, the second supporting surface 1221 being matched with an outer sidewall of the shock absorbing member 121, and the shock absorbing member 121 being supported by the second supporting surface 1221.

Specifically, the supporting wall 141 is provided with a third supporting rib 1412, the inner side wall of the cover 230 is provided with a fourth supporting rib 232, and the third supporting rib 1412 and the fourth supporting rib 232 jointly enclose the second supporting assembly 122. The second supporting element 122 is formed in the same manner as the first supporting element 112, and is not described herein again.

In a specific implementation, the damping member 121 may be a bearing. In order to fix the shock absorbing member 121, the third support rib 1412 and the fourth support rib 232 are both provided with an arc-shaped groove, the arc-shaped grooves on the third support rib 1412 and the fourth support rib 232 are spliced to form an annular accommodating groove 180 (the groove bottom and the side wall of the accommodating groove 180 form a second supporting surface 1221), the bearing is accommodated in the accommodating groove 180, two end surfaces of the bearing are abutted to two side walls of the accommodating groove 180, and the side surface of the bearing is abutted to the bottom wall of the accommodating groove 180 (that is, the cross section of the accommodating groove 180 is U-shaped). This prevents the damper 121 from moving on the worm 221. Alternatively, one end surface of the bearing abuts against one side wall of the receiving groove 180 (that is, the receiving groove 180 has an L-shaped cross section), and the side surface of the bearing abuts against the bottom wall of the receiving groove 180.

In some embodiments, the worm 221 includes two supporting segments 2211 and a tooth segment 2212 connected to the two supporting segments 2211, the tooth segment 2212 is engaged with the turbine 222, the supporting segment 2211 has a second stopping portion 2213, and the shock absorbing member 121 is sleeved on the supporting segment 2211 and abuts between the second supporting assembly 122 and the second stopping portion 2213. Thereby, the damper 121 is prevented from moving on the worm 221.

The worm 221 may further include an insertion section 2114, the insertion section 2114 is connected to any one of the support sections 2211, and the support section 2211 is inserted into the connecting shaft 190.

In the present embodiment, the output shaft 212 of the driving member 210 is connected to the worm 221 through the connecting shaft 190, wherein the two ends of the worm 221 are respectively provided with the second supporting assemblies 122 (i.e. bearings) for fixing the lateral force, and the double bearings are arranged to prevent the worm 221 from being affected by the vibration generated during the rotation of the driving member 210. Because of the characteristics of high dimensional accuracy, small friction coefficient and high transmission efficiency of the bearing, the worm 221 is an important part for transmitting power output in the process of transmitting transverse force, and the fixing of the worm 221 needs to prevent the influence caused by the longitudinal centrifugal force of the worm wheel 222 and the manufacturing tolerance of the worm wheel 222 and the worm 221, and also needs to prevent the influence caused by the output shaft 212 of the driving member 210 on the worm 221, so the fixing of the worm 221 is important.

In this embodiment, the two ends of the worm 221 are fixed together by the second supporting assembly 122 and the second stopping portion 2213, so that the cost is saved while the worm 221 is stably fixed. When the manufacturing tolerance and the like of the driver 210 cause the unbalanced force of the output of the driver 210, the unbalanced force is released through the worm 221, so that the worm 221 can rotate smoothly, the unbalanced output force transmitted to the worm 221 by the driver 210 is reduced, and the output transmission force of the worm 221 can be balanced, so that the damage of the worm 221 to the worm wheel 222 is reduced.

This enables smooth rotation of the turbine shaft 223. The surface of the turbine 222 facing the cover 230 is an abutting portion 2231, and the damper 121 (i.e., the damper 121 located above in fig. 13) abuts between the support portion 170 of the inner sidewall of the cover 230 and the surface of the turbine 222 facing the cover 230. Alternatively, the abutment portion 2231 is located on the turbine shaft 223, and the damper 121 (i.e., the damper 121 located below in fig. 13) abuts between the support portion 170 on the support wall 141 and the abutment portion 2231 on the turbine shaft 223.

The worm 221 drives the worm wheel 222 to rotate, the worm wheel 222 enables the axial force output of the turbine shaft 223 to be more balanced under the action of the two shock absorption pieces 121, the cleaning assembly 300 can rotate stably, when the cleaning assembly 300 is fed back to the turbine shaft 223 due to the fact that a cleaning area is uneven or vibration generated by the cleaning assembly 300 in the rotating process is released through the shock absorption pieces 121, and centrifugal influence and abrasion damage of the turbine shaft 223 on the driving piece 210 and the worm 221 are reduced.
