Detailed Description

The technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings.

Referring to fig. 1 to 4, the present embodiment provides a direct drive floor brush, which includes a main body 1, a driving member, and a detachable and replaceable brush roller 2. The main body portion 1 is internally provided with a containing cavity 3, the brush roller 2 is arranged in the containing cavity 3, and the brush roller 2 is sleeved outside the driving component along the axial direction of the brush roller.

The brush roll 2 comprises an inner cavity extending inwards from a first end portion of the brush roll along the axial direction of the inner cavity, at least part of a driving part is located in the inner cavity, the driving part comprises a fixing portion 6 and a rotating portion 7, the rotating portion 7 is linked with the brush roll 2, the fixing portion 6 comprises a shell 8 and a rotating sleeve 9 sleeved on the shell 8, the rotating sleeve 9 is connected with the shell 8 through a first bearing 10 in an assembling mode, an annular sealing ring 11 is arranged on the outer surface of the rotating sleeve 9, the inner wall of the inner cavity at least comprises a step 14 corresponding to the rotating sleeve 9, and when the brush roll 2 and the main body portion 1 are in an assembling state, the annular sealing ring 11 is.

The rotary sleeve 9 comprises an end face 15 perpendicular to the axial direction, the annular sealing ring 11 being fitted axially to the end face 15. The step 14 is preferably an annular step which is matched to the annular sealing ring 11 and seals off the annular sealing ring 11 when the brush roller 2 is in the assembled state. It is worth integrating that the annular sealing ring 11 is an elastic element which, when it abuts against the step 14, exerts an axial biasing force on the brush roller 2 opposite to the assembly direction of the brush roller 2.

The rotating part 7 is arranged in an inner cavity of the brush roll 2, the rotating part 7 comprises a torque output part, and a groove 16 meshed with the torque output part is arranged on the wall of the inner cavity, so that torque is transmitted.

The two ends of the accommodating cavity 3 are correspondingly provided with a first end plate 4 and a second end plate 5, the fixing part 6 is arranged on the inner side surface of the first end plate 4, and the first end plate 4 can be directly and fixedly connected with the main body part 1 into a whole in consideration of reliable fixation. The second end plate 5 and the main body portion 1 can be detachably connected, the inner side face of the second end plate 5 is provided with a mounting portion 12, the second end portion of the brush roller 2 is assembled and connected with the mounting portion 12 through a second bearing 13, the butt joint force of the brush roller 2 and the driving component is smaller than that of the brush roller 2 and the second end plate 5, and when the second end plate 5 is detached from the main body portion 1, the brush roller 2 is separated from the driving component and is taken out of the cavity 3.

The specific assembly mode is that the inner ring of the second bearing 13 is fixedly sleeved on one of the brush roller 2 and the mounting part 12, and the outer ring of the second bearing 13 is clamped with the other one of the brush roller 2 and the mounting part 12. Here, the second bearing 13 is interference-fitted to the mounting portion 12, and the centering of the brush roller 2, the second bearing 13, and the mounting portion 12 of the second end plate 5 is ensured, thereby improving the degree of fitting. Of course, the above assembly relationship can be reversed, and only the adaptive deformation is required.

In particular, the distance of the step 14 from the first end of the brush roller 2 is no greater than 1/4 of the length of the brush roller 2. In the assembled state, the distances from the first bearing 10 to the first end and from the second bearing 13 to the second end are equal.

The abutment force of the brush roll 2 against the drive member is smaller than the abutment force of the brush roll 2 against the second end plate 5, and when the second end plate 5 is detached from the main body portion 1, the brush roll 2 is detached from the drive member and removed from the container 3. Because the butt joint force of the brush roll 2 and the driving part is smaller than the butt joint force of the brush roll 2 and the second end plate 5, the brush roll 2 and the driving part are necessarily separated firstly during disassembly, an assembly of the brush roll 2 and the second end plate 5 is obtained, and the brush roll 2 and the second end plate 5 can be further disassembled later according to requirements.

The second end plate 5 and the main body part 1 can be detachably connected, one of the second end plate and the main body part 1 is provided with an unlocking part 17, the unlocking part 17 is in linkage with the bolt 18, the other of the second end plate 5 and the main body part 1 is provided with a clamping groove corresponding to the bolt 18, the bolt 18 is driven by the unlocking part 17 to exit from the clamping groove, and therefore the second end plate 5 and the main body part 11 are in contact locking. Of course, snap-fit or other fastening means may be used.

The embodiment also provides a cleaning device which comprises the direct-drive ground brush so as to more conveniently perform device maintenance.

To sum up, this directly drive scrubbing brush and cleaning equipment can make the brush roll take out along the axial through dismantling the second end plate, convenient cleanness, change, easy operation, and the sealing washer that adds between brush roll and the driver part can improve axial leakproofness, eliminates production tolerance or assembly error, and the noise reduction more can provide axial biasing force for the brush roll is more laborsaving when dismantling, assembles fast, reliably, and the transmission is stable, has fine use sense.

The above embodiments have been merely illustrative of the basic principles and features of the present invention, and the present invention is not limited by the above embodiments, and does not depart from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
