According to some embodiments of the present invention, as shown in fig. 6, the driving device 16 includes: drive motor 18, drive gear 181, first transmission assembly and second transmission assembly. The drive motor 18 has a drive shaft to which a drive gear 181 is fixed coaxially. The first transmission component is in transmission connection between the driving gear 181 and the scraping sleeve 13, and the second transmission component is in transmission connection between the driving gear 181 and the rolling brush body 11. Like this, driving motor 18 drives drive gear 181 and rotates, and drive gear 181 drives through first transmission assembly and scrapes cover 13 and rotate, and drive gear 181 drives the rolling brush body 11 through second transmission assembly and rotates to can reach the simultaneous drive rolling brush body 11 and scrape cover 13 pivoted purpose, and stable in structure.

For example, the driving gear 181 and the scraping sleeve 13, and the driving gear 181 and the rolling brush body 11 may be in transmission connection through a plurality of gears, or the driving gear 181 and the scraping sleeve 13, and the driving gear 181 and the rolling brush body 11 may be in transmission connection through the cooperation between the transmission belt and the gears.

In some embodiments of the invention, as shown in fig. 5 and 6, the first transmission assembly comprises: a first transmission gear 19 and a first drive belt 20.

The first drive belt 20 is tensioned between the drive gear 181 and the first transmission gear 19 to maintain the belt at a proper tension during transmission to prevent the belt from slipping or slipping out of gear due to jumping or derailing of the belt.

In this way, the driving gear 181 drives the first driving belt 20 to move, and the first driving belt 20 drives the first transmission gear 19 to rotate so as to drive the scraping sleeve 13 to rotate, so that the structure is simple and reliable.

In some embodiments of the invention, as shown in fig. 7, the first transmission gear 19 comprises: a first drive ring 191 and a first connecting ring 192.

The outer surface of the first transmission ring 191 is formed with first transmission teeth 1911 for meshing transmission with the first drive belt 20, one end of the first connection ring 192 is connected to a side of the first transmission ring 191 facing the scraper sleeve 13, and the other end of the first connection ring 192 is connected to the scraper sleeve 13. Thus, the first driving belt 20 rotates the first transmission ring 191 to rotate the first connection ring 192 synchronously, thereby rotating the scraper sleeve 13 synchronously. For example, the right end of the first connection ring 192 is connected with the left side of the first transmission ring 191, and the left end of the first connection ring 192 is sleeved on the outer circumferential wall of the scraping sleeve 13, wherein the first transmission ring 191 and the first connection ring 192 can be an integral piece, so that the integration level is high, the structure is compact, and the corresponding assembly is omitted; the first drive ring 191 and the first link ring 192 may also be two separate pieces.

Optionally, as shown in fig. 5 and 6, the first transmission assembly further includes: a compression ring 23. The pressing ring 23 is fitted over the first connecting ring 192, and the pressing ring 23 is used to press the first connecting ring 192 against the outer peripheral wall of the scraper sleeve 13. In this way, the first connection ring 192 is clamped between the pressing ring 23 and the scraping sleeve 13, so that the connection of the first connection ring 192 with the scraping sleeve 13 is more secure.

In some embodiments of the present invention, as shown in fig. 5 and 6, the second transmission assembly comprises: a second transmission gear 21 and a second drive belt 22.

The second transmission gear 21 is connected to the roller brush body 11. The second transmission gear 21 and the rolling brush body 11 can be two separate parts, and the second transmission gear 21 is connected to the rolling brush body 11 through a threaded connection, an adhesive connection and the like; alternatively, the second transmission gear 21 is formed integrally with the roller body 11, for example, gear teeth are formed on the outer circumferential wall of the roller body 11, thereby simplifying the assembling process.

The second driving belt 22 is tensioned between the driving gear 181 and the second transmission gear 21 to maintain a proper tension of the belt during the transmission, thereby preventing the belt from slipping or being dragged out due to jumping and derailing of the belt.

Therefore, the driving gear 181 drives the second driving belt 22 to move, and the second driving belt 22 drives the second transmission gear 21 to rotate so as to drive the rolling brush body 11 to rotate, so that the structure is simple and reliable.

In some embodiments of the present invention, as shown in fig. 8, the second transmission gear 21 includes: engaging the ring plate 211, the coupling sleeve 212 and the radial plate.

The engaging ring plate 211 is formed in a cylindrical shape extending in the axial direction, and second transmission teeth 2111 are formed on an outer surface of the engaging ring plate 211, and the second transmission teeth 2111 are engaged with the second drive belt 22 for transmission. The coupling sleeve 212 is formed in a cylindrical shape extending in the axial direction of the roll brush body 11, the coupling sleeve 212 is located inside the engagement ring plate 211, and one end of the coupling sleeve 212 facing the roll brush body 11 is connected to the roll brush body 11. The radial plates extend in the radial direction of the roller brush body 11, and the radial plates are connected to the engaging ring plate 211 and the coupling sleeve 212, respectively. Thus, the second driving belt 22 rotates the engaging ring plate 211, the engaging ring plate 211 drives the connecting sleeve 212 to rotate synchronously, and the connecting sleeve 212 drives the rolling brush body 11 to rotate synchronously.

For example, the engaging ring plate 211 and the connecting sleeve 212 extend in the left-right direction, the radial plate is circular, the left end of the connecting sleeve 212 is connected to the roller brush body 11, the right end of the connecting sleeve 212 is connected to the inner peripheral wall of the radial plate, and the left end of the engaging ring plate 211 is connected to the outer peripheral wall of the radial plate. The engaging ring plate 211, the connecting sleeve 212 and the radial plate can be an integral piece, so that the integration level is high, the structure is compact, and corresponding assembly is omitted.

Optionally, as shown in fig. 5, the second transmission assembly further comprises: a drive shaft. The connecting sleeve 212 is sleeved on the transmission shaft, and one end of the transmission shaft facing the rolling brush body 11 is connected with the rolling brush body 11. Therefore, the connecting sleeve 212 drives the transmission shaft to synchronously rotate, so as to drive the rolling brush body 11 to synchronously rotate, and the connecting sleeve 212 and the rolling brush body 11 are convenient to connect and assemble.

In some embodiments of the present invention, the first transmission gear 19 and the second transmission gear 21 have the same number of teeth.

As shown in fig. 5 and 6, the driving motor 18 drives the driving gear 181 to rotate, and the first driving belt 20 and the second driving belt 22 are driven by the driving gear 181 to move at the same linear velocity, respectively, so that the first transmission gear 19 and the second transmission gear 21 have the same number of teeth, that is, the ratio of the number of teeth of the first transmission gear 19 to the driving gear 181 is the same as the ratio of the number of teeth of the second transmission gear 21 to the driving gear 181, thereby ensuring that the first transmission gear 19 and the second transmission gear 21 rotate synchronously at the same angular velocity. And, the first transmission gear 19 drives the scraper sleeve 13 to rotate synchronously at the same angular velocity, and the second transmission gear 21 drives the roller brush body 11 to rotate synchronously at the same angular velocity.

In this way, it is ensured that the scraper sleeve 13 and the roller brush body 11 rotate synchronously at the same angular speed, thereby ensuring the mutual correspondence of the positions of the bristles 12 and the scraper sleeve holes 1311 in the circumferential direction, and further ensuring that the bristles 12 are adapted to extend and retract into the corresponding scraper sleeve holes 1311 in the radial direction of the scraper sleeve 13.

In some embodiments of the invention, two pairs of belts and pulleys of meshing detail may be used instead of the first transmission gear 19 and the first drive belt 20, and the second transmission gear 21 and the second drive belt 22. Therefore, the use risk can be reduced, the service life can be prolonged, the transmission efficiency can be ensured, and the engagement details can avoid the problem of paper jam caused by assembly errors or belt tooth jumping.

According to some embodiments of the present invention, the distance between the free ends of the brush staples 12 and the first rotation central axis is not less than the maximum distance between the first rotation central axis and the inner circumferential wall of the scraper sleeve 13 in the radial direction of the drum brush body 11, and thus, in the rotating process of the rolling brush body 11 and the scraping sleeve 13, the brush hairs 12 on the rolling brush body 11 in a fully retracted state, the free end of the scraper sleeve can be positioned in the scraper sleeve hole 1311 and between the inner circumferential wall and the outer circumferential wall of the scraper sleeve 13, or can slightly extend out of the scraper sleeve hole 1311 in the radial direction and exceed the outer circumferential wall of the scraper sleeve 13, thus, on one hand, the scraping sleeve 13 is convenient for scraping the hair attached to the brush to the maximum extent, on the other hand, at least one part of the brush hair can be always positioned in the scraping sleeve hole, the free end of the brush hair is prevented from being completely separated from the scraping sleeve hole when retracting, thereby ensuring that the bristles 12 smoothly extend and retract in the direction of the through-holes of the grommet hole 1311.

According to some embodiments of the present invention, as shown in fig. 9 to 13, the brush bristles 12 are included in a plurality spaced apart in both circumferential and axial directions of the roller brush body 11, and the scraping sleeve holes 1311 are included in a plurality, and the plurality of scraping sleeve holes 1311 correspond to the plurality of brush bristles 12 one to one, whereby the cleaning efficiency of the cleaner 100 can be improved. For example, a first bristle group and a second bristle group may be disposed at intervals in the circumferential direction of the rolling brush body 11, each bristle 12 group includes a plurality of bristles 12, and the plurality of bristles 12 may be arranged in a spiral line on the rolling brush body 11 along the direction of the first rotation center line; correspondingly, the circumferential direction of the scraping sleeve 13 can be provided with a first scraping sleeve hole group and a second scraping sleeve hole group at intervals, each scraping sleeve hole 1311 group comprises a plurality of scraping sleeve holes 1311, the scraping sleeve holes 1311 can be arranged on the scraping sleeve 13 along a spiral line along the direction of the second rotation center line, and the scraping sleeve holes 1311 correspond to the bristles 12 one to one.

In some embodiments of the invention, the diameter of the bristles 12 may be less than the minimum width dimension of the scraper sleeve hole 1311. Thus, the bristles 12 are easily extended or retracted from the casing scraping hole 1311, and the bristles 12 are prevented from being caught in the casing scraping hole 1311.

Because the scraping sleeve 13 and the rolling brush body 11 have an eccentric distance between the central rotation axes thereof, when the scraping sleeve 13 and the rolling brush body 11 rotate synchronously, the rolling brush body 11 has a rotation motion relative to the scraping sleeve 13 by taking the eccentric distance between the two central rotation axes as a radius, the bristles 12 arranged on the rolling brush body 11 also follow the rotation motion of the rolling brush body 11 relative to the scraping sleeve 13 by taking the eccentric distance between the two central rotation axes as a radius, and in order to ensure that the bristles 12 have a sufficient movement space in the circumferential direction of the scraping sleeve 13, according to some embodiments of the present invention, the length dimension of the scraping sleeve hole 1311 in the circumferential direction of the scraping sleeve 13 is not less than 2 times of the eccentric distance between the first central rotation axis and the second central rotation axis, so that the bristles 12 can have a sufficient stroke in the scraping sleeve hole 1311, and the scraping sleeve 13 is ensured not to interfere with the relative rotation motion of the rolling brush body 11.

In some embodiments of the present invention, as shown in fig. 9 to 13, the wiper hole 1311 is formed as an elongated groove extending in the circumferential direction of the wiper 13. Thus, the bristles 12 can make a telescopic motion relative to the scraper sleeve hole 1311 along the radial direction of the rolling brush body 11 and make a circular motion in the scraper sleeve hole 1311, and the bristles 12 are prevented from interfering with the peripheral wall of the scraper sleeve hole 1311.

According to some embodiments of the present invention, as shown in fig. 9 to 13, the grommet hole 1311 includes a first hole portion 13111 and a second hole portion 13112, the first hole portion 13111 and the second hole portion 13112 are connected in a circumferential direction of the grommet 13, the first hole portion 13111 is formed in a circular shape, and the second hole portion 13112 extends away from the first hole portion 13111 in the circumferential direction of the grommet 13, wherein a width dimension of the second hole portion 13112 in an axial direction of the grommet 13 is smaller than a diameter of the first hole portion 13111, so that the first hole portion 13111 and the second hole portion 13112 can cooperate with each other to define a movement path for the bristles 12, while making movement of the bristles 12 smoother. In addition, since the width dimension of the second hole 13112 is smaller, it is further advantageous to scrape off the hairs on the bristles by the side walls of the grommet hole 1311.

In some embodiments of the present invention, as shown in fig. 9 to 13, the peripheral wall of the second hole 13112 at the end far from the first hole 13111 is a circular cylindrical surface, so that the shape of the second hole 13112 can be matched with the shape of the bristles 12, and the bristles 12 can be prevented from being caught.

According to some embodiments of the present invention, as shown in fig. 9 to 13, a plurality of ribs 1111 (for example, a first rib and a second rib described below) are formed on the outer circumferential wall of the roller brush body 11, the plurality of ribs 1111 spirally extend along the axial direction of the roller brush body 11, a plurality of bristles 12 are provided on the outer end surface of each rib 1111, the plurality of bristles 12 are arranged at intervals in the extending direction of the rib 1111, and by providing the ribs 1111 and disposing the bristles 12 on the ribs 1111, the length of the bristles 12 can be reduced, the rigidity of the bristles 12 can be ensured, and the cleaning efficiency can be ensured.

For example, as shown in fig. 10, two ribs 1111 may be formed on the outer circumferential wall of the roller brush body 11, the two ribs 1111 are respectively a first rib and a second rib, the two ribs 1111 all extend spirally along the axial direction of the roller brush body 11, a first bristle group is arranged on the first rib, a second bristle group is arranged on the second rib, a plurality of bristles 12 of the first bristle group are arranged at intervals in the extending direction of the first rib, a plurality of bristles 12 of the second bristle group are arranged at intervals in the extending direction of the second rib, thereby ensuring that the bristles 12 on the roller brush body 11 can always act on the ground to clean the ground in the working process of the vacuum cleaner 100, and further simplifying the structure of the roller brush body 11.

Of course, the present invention is not limited thereto, and the roller brush body 11 may be formed with three ribs 1111 and bristle groups corresponding to the three ribs 1111 one by one, and correspondingly, the scraper sleeve 13 may be formed with three scraper sleeve hole groups corresponding to the three bristle groups one by one.

Further, as shown in fig. 9 to 13, the roll brush body 11 may include: a first roller body portion 111 and a second roller body portion 112. Specifically, the first roller brush body part 111 and the second roller brush body part 112 are sequentially arranged in the axial direction, the rotation direction of the convex rib 1111 on the first roller brush body part 111 is opposite to that of the convex rib 1111 on the second roller brush body part 112, and the convex rib 1111 on the first roller brush body part 111 is connected with the convex rib 1111 on the second roller brush body part 112, so that two parts of the roller brush body 11 in the axial direction can simultaneously clean the ground in the working process of the dust collector 100, and the part of the ground through which the dust collector 100 passes is prevented from being omitted.
