Detailed Description

The embodiment of the utility model provides a mop subassembly, this mop subassembly can be used for washing the ground machine to clean ground. As shown in fig. 1 and 2, the mop assembly includes a housing, which may include an upper housing 4 and a lower housing 5. The upper and lower housings 4 and 5 define an accommodation space in which, for example, a water pump 6, a control assembly 7, etc. may be disposed. The water pump 6 is used to supply water to the drum brush 21 when the scrubber is in operation, so as to clean the floor. The control assembly 7 may be used to control the start and stop of the water pump 6, the rotation and stop of the roller brush 21, etc.

As shown in fig. 2, the mop assembly of the embodiment of the present invention further includes a long arm driving mechanism 1, a rolling brush assembly 2 and an end cover assembly 3. The long arm drive mechanism 1 is provided in the housing (see fig. 1 and 2). As shown in fig. 3, the long arm drive mechanism 1 includes a power source 11 and a transmission shaft 12. As shown in fig. 5, the first end of the transmission shaft 12 is drivingly connected to the power source 11. The power source 11 can drive the transmission shaft 12.

As shown in fig. 4, the roller brush assembly 2 includes a roller brush 21, and a shaft hole (not shown) is formed in the roller brush 21 and extends from a first end of the roller brush 21 in the axial direction to at least a middle portion of the roller brush 21. The rolling brush 21 is sleeved outside the transmission shaft 12 through the shaft hole, that is, the transmission shaft 12 is penetrated in the shaft hole, and the second end of the transmission shaft 12 is extended to the bottom of the hole close to the shaft hole. When the transmission shaft 12 is rotated by the power source 11, the transmission shaft 12 rotates the roller brush 21 together.

As shown in fig. 4, the end cap assembly 3 includes an end cap 31 and a locking member, and the end cap 31 is provided at a second end of the roller brush 21 for supporting the roller brush 21 to allow the roller brush 21 to smoothly rotate. The locking member is used to lock or unlock the end cap 31 with the housing. A part of the locking member is provided on the housing and a part is provided on the side of the end cover 31 extending in the radial direction, which does not occupy the space in the axial direction of the roll brush 21 and does not affect the distance from the roll brush 21 to the edge. By locking the end cap 31 with the housing by the locking member, the movement of the roll brush 21 in the axial direction thereof can be restricted to restrain the roll brush 21 on the sleeve 16. When the locking member releases the locking of the end cap 31 with the housing, the roller brush 21 can be moved in the axial direction thereof to enable the roller brush 21 to be detached from the sleeve 16.

The utility model discloses mop the subassembly, its round brush subassembly 2 stretches into round brush 21 inside by long arm actuating mechanism 1 and drives, and the drive position degree of depth that stretches into reaches round brush 21 intermediate line at least, make the main focus of round brush subassembly 2 just on long arm actuating mechanism 1, and the second end of round brush 21 only sets up end cover 31, end cover 31's thickness is thinner, make the round brush 21 only be end cover 31's wall thickness to the distance on limit, end cover 31's wall thickness for example can be for 2mm, therefore, can reduce the corner and clean the blind area, the reinforcing corner cleans the ability.

In some embodiments, the long arm driving mechanism further includes a sleeve 16 and a transmission head 13, the sleeve 16 is sleeved outside the transmission shaft 12, the first end and the second end of the transmission shaft 12 respectively extend out of the sleeve 16, the second end of the transmission shaft 12 is connected to the transmission head 13, and the transmission shaft 12 drives the rolling brush 21 to rotate together through the transmission head 13. By arranging the sleeve 16, the transmission shaft 12 and the rolling brush 21 can be supported, and the stability of the transmission shaft and the rolling brush can be ensured. The effectiveness and stability of the transmission can be ensured by the transmission head 13.

It will be appreciated that the sleeve 16 is stationary and the drive shaft 12 is rotated relative to the sleeve 16 by the power source 11. To achieve the fixation of the sleeve 16, the second end of the sleeve 16 needs to extend out of the shaft hole. The sleeve 16 may be fixed to the housing or to the motor bracket 111 (described below). In fact, as long as it is ensured that the sleeve 16 is fixed, as for how to realize the fixation of the sleeve 16, the present invention is not specifically limited.

As shown in fig. 1, when the rolling brush 21 is installed on the transmission shaft 12 and the casing 16, the downward side of the rolling brush 21 is exposed out of the casing to contact the ground surface for cleaning the ground surface. Since the rolling brush 21 is rolled in the operating state, the side of the rolling brush 21 facing downward does not refer to a specific portion of the rolling brush 21 but refers to a portion facing downward during rolling. End cover 31 of the second end of round brush 21 exposes and flushes with the casing, so, when clean, round brush 21 only is end cover 31's wall thickness with the distance to the corner, has reduced clean blind area, improves user's the experience satisfaction that cleans greatly.

In some embodiments, as shown in fig. 5, the driving shaft 12 is provided with first bearings 14 near both ends thereof, and the first bearings 14 are used for supporting the driving shaft 12 and enabling the driving shaft 12 to rotate relative to the sleeve 16.
