In this embodiment, "traveling direction" refers to a direction in which the cleaning apparatus is traveling in a straight line on the surface to be cleaned, and the terms "front", "rear", "upper" and "lower" are defined when the cleaning apparatus is in the traveling direction, wherein "front" refers to the same direction as the traveling direction and "rear" refers to a direction opposite to the traveling direction.

As shown in fig. 1A and 1B, the present embodiment provides a cleaning apparatus mainly including a main body 30 and a rolling brush 10 provided at the bottom of the main body 30, wherein the rolling brush 10 contacts a surface P to be cleaned and collects dust, hair, debris, etc. on the surface P to be cleaned into the main body 30 during the travel of the main body 30 along the surface P to be cleaned.

In one embodiment, the main body 30 includes a dust box 31 and a dust suction opening 200, the dust suction opening 200 is located at the bottom surface of the main body 30 and faces the surface P to be cleaned, the dust box 31 is located in the main body 30, the dust suction opening 200 is communicated with the dust box 31 through a dust suction channel, and by connecting the dust box 31 to a negative pressure device, garbage below the dust suction opening 200 can be sucked into the dust box 31 from the dust suction opening 200 by utilizing the negative pressure, and cleaning and collection of the garbage can be performed, for example, the negative pressure device is a fan built in or external to the main body 30. The roller brush 10 may be disposed at the dust suction port 200, and the roller brush 10 at least partially protrudes out of the dust suction port 200. As the main body 30 walks along the surface P to be cleaned, the roller brush 10 also collects the dust of the surface P to be cleaned toward the inside of the dust suction port 200 during rotation.

In one embodiment, the cleaning device includes a travelling mechanism 40 disposed at the bottom thereof, and in fig. 1A and 1B, the travelling mechanism 40 is illustrated as a travelling wheel, the travelling mechanism 40 includes a pair of travelling wheels coaxially disposed, and the two travelling wheels are disposed at two ends of the dust suction port 200 in the length direction, respectively, and the rotation axis thereof is perpendicular to the travelling direction of the cleaning device. In other embodiments, the travelling mechanism 40 may be a travelling disk that protrudes toward the surface to be cleaned P to be in surface contact with the surface to be cleaned P, and the travelling disk may be moved on the surface to be cleaned P by rotating the travelling disk.

Illustratively, the dust collection opening 200 is located in front of the travelling direction of the cleaning device (in the arrow direction shown in fig. 1B) relative to the travelling mechanism 40, the rolling brush 10 rotates in the counterclockwise direction shown in fig. 1B, so that the travelling mechanism 40 can always travel on the travelling surface after the cleaning of the garbage by the rolling brush 10, and secondary pollution caused by adhesion of the garbage to the travelling mechanism 40 is avoided.

In one embodiment, the cleaning mechanism 50 may be further provided on the main body 30 of the cleaning apparatus at the rear of the traveling direction of the cleaning apparatus, i.e., the roller brush 10 is in front, and the roller brush 10 may collect dry trash such as dust, hair, chips, etc. after the cleaning mechanism 50 is in rear. Illustratively, the cleaning mechanism 50 may include a rag that cleans the surface P to be cleaned of dirt, water, etc., that cannot be collected by the roller brush 10. As shown in fig. 1A, two cleaning mechanisms 50 are provided on both sides of the main body 30 (i.e., in the axial direction of the roll brush 10), respectively.

In one embodiment, the cleaning apparatus may further include a universal wheel 60, the universal wheel 60 being disposed behind the travel direction of the cleaning apparatus with respect to the roller brush 10, for example, the cleaning mechanism 50 being located between the roller brush 10 and the universal wheel 60, the universal wheel 60 further supporting the main body 30, ensuring that the main body 30 remains balanced during travel and achieving assisted steering.

In addition, in some embodiments, the cleaning apparatus may further include a side brush 70, at least one side brush 70 being disposed beside the roller brush 10 for sweeping the garbage around the dust suction opening 200 into the dust suction opening 200 during rotation, and collecting the garbage into the dust box 31 by negative pressure. In order to enhance the cleaning effect of the side brush 70, the bristles of the side brush 70 extend at least partially to face the dust collection opening 200, so that the garbage collected during the rotation of the side brush 70 can be guided to the lower side of the dust collection opening 200 along the side brush 70, and then the garbage is swept into the dust collection opening 200 by the roller brush 10 and sucked into the dust box 31 by negative pressure. In fig. 1A, two side brushes 70 are respectively disposed on the left and right sides of the dust suction opening 200 and are located in front of the travelling direction of the cleaning device relative to the roller brush 10, and the rotation directions of the two side brushes 70 are opposite, for example, the left side brush 70 rotates clockwise and the right side brush 70 rotates counterclockwise, so that the two side brushes 70 and the roller brush 10 enclose a U-shaped cleaning area, and the garbage passing through the travelling path of the cleaning device can be cleaned to the greatest extent, thereby avoiding the garbage from leaking from the lower side of the cleaning device to affect the cleaning mechanism 50 and improving the cleaning effect.

As shown in fig. 2 and 5 in combination, the present embodiment provides a roller brush 10, the roller brush 10 including:

a roll brush body 11;

a brush part 12 provided on the outer circumferential surface of the roll brush body 11, including a working section 121 for contacting the surface P to be cleaned and a connecting section 122 connecting the roll brush body 11 and the working section 121;

a plurality of blocking parts 13 arranged at intervals along the circumferential direction of the rolling brush body 11, at least one blocking part 13 being arranged on the rolling brush body 11 and/or the brush part 12, and both ends of the blocking part 13 extending toward both axial ends of the rolling brush body 11, respectively;

the distance from the free end of the blocking portion 13 to the central axis of the roll brush body 11 is not greater than the distance from the end of the connection section 122 remote from the roll brush body 11 to the central axis of the roll brush body 11 so that the free end of the blocking portion 13 is kept spaced apart from the surface P to be cleaned when the working section 121 contacts the surface P to be cleaned.

The blocking portion 13 may be a rubber strip, such as a rubber strip, a silica gel strip, or a plastic strip, having a certain deformability. The "working section 121" herein refers to a portion located at the end of the brush part 12, which includes all portions of the brush part 12 that can contact the surface P to be cleaned during rotation of the roll brush 10; the "connecting section 122" is a portion of the brush part 12 for connecting the working section 121, which does not contact the surface P to be cleaned during rotation of the roll brush 10. Since the distance from the end of the blocking portion 13, which is remote from the roll brush body 11, to the center axis of the roll brush body 11 is at least the same or even smaller, the blocking portion 13 does not contact the surface P to be cleaned.

As shown in fig. 1B, 2 and 5, a horizontal line tangent to the movement locus of the free end of the stopper 13 is located between the central axis of the roll brush body 11 and a horizontal line tangent to the running surface of the running mechanism 40. That is, the distance from the free end of the blocking portion 13 to the reference surface of the main body 30 when passing the lowest point is smaller than the distance from the lowest point of the running mechanism 40 to the reference surface of the main body 30. The "lowest point" here refers to a point on the free end of the blocking portion 13 closest to the surface P to be cleaned during rotation of the roll brush, and the reference surface of the main body 30 may be the bottom surface of the main body 30 or any surface parallel to the horizontal surface passing through the main body 30. Similarly, the "distance from the lowest point of the running gear to the reference surface of the main body" refers to the distance from the nearest point on the running gear 40 to the surface P to be cleaned to the reference surface of the main body 30. In this way, during the travel of the cleaning device, the travelling mechanism 40 is in frictional contact with the surface P to be cleaned, the working section 121 of the brush portion 12 is in contact with the surface P to be cleaned, and the free end of the blocking portion 13 is always spaced from the surface P to be cleaned.

By setting the length of the blocking portion 13 such that the free end thereof is close to the working section 121 without protruding out of the connecting section 122, the connecting section 122 and the blocking portion 13 cannot contact the surface P to be cleaned, thereby maintaining a gap with the surface P to be cleaned, so that, during cleaning, only the working section 121 at the end of the brush portion 12 is in rotational contact with the surface P to be cleaned to sweep away the dust, and thus, the situation that the blocking portion 13 contacts the surface P to be cleaned to generate noise does not occur, and, due to the restriction of the blocking portion 13, if hair is wound around the roller brush 10, the hair cannot continue to be deep toward the connecting section 122 because the blocking portion 13 is blocked from penetrating into the working section 121, and therefore, the hair can be easily cleaned from the roller brush 10, and the cleaning effect and the hair cleaning convenience can be compromised.

FIG. 3 shows a schematic view of an assembled structure of a roll brush; FIG. 4 shows a partially exploded view of a roller brush; fig. 5 is a schematic sectional view of a roll brush.

In some embodiments, at least one blocking portion 13 is provided between every two adjacent brush portions 12, and the cleaning device may also comprise a plurality of brush portions 12. As shown in fig. 3 to 5, there is shown a case in which the roll brush 10 includes 2 brush parts 12, the 2 brush parts 12 being disposed at intervals in the circumferential direction of the roll brush body 11, a plurality of blocking parts 13 being provided between the 2 brush parts 12, for example, a left side of the brush parts 12, a right side of the brush parts 12 being each provided with a plurality of blocking parts 13, the blocking parts 13 having a smaller length in the radial direction of the roll brush 10 than the brush parts 12, and having ends not exceeding the connection section 122, i.e., the length of the blocking parts 13 in the radial direction of the roll brush 10 may coincide with the length of the connection section 122 in the radial direction of the roll brush 10, or may be smaller than the length of the connection section 122 in the radial direction of the roll brush 10. In some embodiments, the number of the blocking parts 13 may be at least four, and thus, the four blocking parts 13 disposed at intervals in the circumferential direction may form a hair winding surface more closely like a circular ring, so that the hair is difficult to access the roll brush body 11, and thus is more easily cleaned.

It will be appreciated that in other embodiments, the number of brush portions 12 and blocking portions 13 may be increased or decreased as required, which is not limited in this example.

The blocking portion 13 does not contact the surface P to be cleaned, but there are special cases where, for example, when there are some wastes with large particles on the surface P to be cleaned, the blocking portion 13 may contact the wastes during the rotation of the roller brush 10. In some embodiments, the free end of at least one blocking portion 13 is disposed obliquely, and the direction of inclination of the free end of the blocking portion 13 is opposite to the rotation direction of the roll brush body 11. As shown in fig. 1B and 5, the cleaning apparatus travels forward, the roller brush 10 rotates counterclockwise, and the free end of the blocking portion 13 is inclined in a clockwise direction.

Thus, in the travelling process of the cleaning device, the angle between the blocking part 13 and the surface to be cleaned P is smaller than that of the brush part 12, when the large particle garbage on the surface to be cleaned P is encountered, the brush part 12 cleans the particle, the blocking part 13 is easier to deform because of the smaller angle between the blocking part and the surface to be cleaned P, so that the roller brush 10 is prevented from being in hard contact with the large particle, damage to the roller brush 10 is avoided to a certain extent, and large noise is avoided.

In some embodiments, a blocking portion 13 having a free end inclined is provided adjacent to one brush portion 12 in the circumferential direction of the roll brush body 11, and the blocking portion 13 can limit the depth of the hair caught in the adjacent brush portion 12. As shown in fig. 5, when one blocking portion 13 is provided beside each brush portion 12, the hair wound in each brush portion 12 is not excessively deep.

As shown in fig. 5, the blocking portion 13, the free end of which is obliquely disposed, is located in front of the brush portion 12 adjacent thereto in the rotation direction of the roll brush body 11, so that the free end of the blocking portion 13 is inclined toward and approaches the adjacent brush portion 12, and the blocking portion 13 is more effective in restricting the hair from sinking into the adjacent brush portion 12.

It will be appreciated that this embodiment shows the free end of the blocking portion 13 spaced from the brush portion 12. In other embodiments, at least part of the free end of the blocking portion 13 may also remain in contact with the brush portion 12.

In some embodiments, the at least one blocking portion 13 and/or the at least one brush portion 12 is detachably connected with the roll brush body 11. As shown in fig. 5, each blocking portion 13 and one end of each brush portion 12 are detachably provided to the roll brush body 11. For example, a plurality of mounting grooves are formed in the circumferential direction of the rolling brush body 11, and the blocking portion 13 and the brush portion 12 are embedded in the corresponding mounting grooves of the rolling brush body 11. In order to facilitate the inclined arrangement of the blocking portion 13 relative to the brush portion 12, the brush portion 12 and the blocking portion 13 are respectively disposed at different positions on the roller brush body 11.

In some embodiments, at least one end of the blocking portion 13 extends out of the axial end of the roll brush body 11, and the brush portion 12 and/or the blocking portion 13 are spirally disposed around the circumferential direction of the roll brush body 11. As shown in fig. 3 to 5, the brush portion 12 and the blocking portion 13 are each spirally provided around the circumferential direction of the roll brush body 11, so that a single brush portion 12, blocking portion 13 can extend in both the axial direction and the circumferential direction of the roll brush body 11. Since the end of the blocking portion 13 extends beyond the axial end of the roller brush body 11, hair can be guided to the lengthwise end of the blocking portion 13 along the spiral surface of the blocking portion 13 for collection during rotation of the roller brush 10.

In some embodiments, at least one end of the roller brush 10 is frustoconical. As shown in fig. 6, both axial ends of the roller brush 10 are formed in a circular truncated cone shape, and the radial dimension of the roller brush 10 is gradually reduced from the middle toward both ends thereof, so that the hair wound in the middle of the roller brush 10 can be guided to both ends of the roller brush 10 along the brush portion 12 of the surface of the roller brush 10 to facilitate collection. It will be appreciated that in other embodiments, it is also possible that only one end of the roller brush 10 is frustoconical, or that the roller brush 10 is generally frustoconical, such that the radial dimension of the roller brush 10 decreases from one end to the other, thereby collecting hair to the smaller radial dimension end of the roller brush 10.

In some embodiments, the roll brush 10 further includes an end cap detachably provided to at least one axial end of the roll brush body 11, and it is convenient to assemble the roll brush 10 to the body 30 and to disassemble the roll brush 10 from the body 30. As shown in fig. 3 and 4, the roll brush 10 has illustratively two end caps 21, a first end cap 201 and a second end cap 202, respectively. The cleaning apparatus includes a transmission mechanism for driving the roller brush 10, the transmission mechanism including a first end cap 201 and a second end cap 202 at both ends of the roller brush 10, wherein the second end cap 202 may be a driving wheel or a part thereof connected to a motor to transmit torque, the driving wheel driving the roller brush 10 to rotate, one end of the first end cap 201 forming a supporting part fixed to the main body 30, and the other end being rotatable with respect to the supporting part such that the roller brush 10 is rotatably supported therein. As shown in fig. 2 and 3, between the first end cap 201 and the axial end of the roller brush 10, the second end cap 202 is axially spaced from the axial end of the roller brush 10, forming a receiving groove 22 for storing hair, the receiving groove 22 being configured as a ring-shaped groove around the rotational axis of the roller brush 10. In other embodiments, the accommodating groove 22 may be provided directly in the end cap 21. The end of the blocking portion 13 extends to the outside of the axial end of the rolling brush main body 11 and does not exceed the corresponding end caps 201 and 202, so that the end of the blocking portion 13 corresponds to the accommodating groove 22 between each end cap and the axial end of the rolling brush 10, and hair can be guided to the two ends of the blocking portion 13 along the spiral surface of the blocking portion 13 and finally enter the accommodating groove 22, thereby facilitating centralized cleaning.

In one embodiment, both ends of the roller brush 10 may be connected to the corresponding first and second end caps 201 and 202, respectively, through the fixing plate 101. Illustratively, the fixed disk 101 has a larger diameter than the roller brush body 11, and thus has a certain blocking effect, preventing dust and other waste from entering the transmission mechanism at the end of the roller brush 10 in the axial direction, and only allowing hair to be guided to the end of the roller brush 10 along the surface (e.g., the blocking portion 13) of the roller brush 10, thereby being collected in the corresponding receiving groove 22.

Fig. 5 shows a case where the brush parts 12, 13 are respectively connected to the outer circumferential surface of the roll brush body 11, and in some embodiments, at least one brush part 12 is connected to the roll brush body 11, and the blocking part 13 is fixed to the brush part 12 instead of the roll brush body 11.

For example, fig. 7 shows a roller brush 10 different from that of fig. 5 in that a brush part 12 is attached to a roller brush body 11, and a blocking part 13 is fixed to the brush part 12, specifically, the blocking part 13 is attached at the interface of a working section 121 and a connecting section 122. During operation of the roller brush 10, the blocking part 13 rotates synchronously with the brush part 12, and can block hairs in the working section 121, limit the hairs from further entering the connecting section 122 along the brush, and the hairs are limited to a shallower depth on the brush part 12 due to the shorter working section 121, so that the hairs can be cleaned conveniently and quickly.

As another example, fig. 8 shows another roller brush 10 different from fig. 5, in which the blocking portion 13 is connected to the roller brush body 11, the brush portion 12 fixes the free end of the blocking portion 13, the brush portion 12 may include a working section 121 and a connecting section 122, and the connecting section 122 connects the working section 121 and the blocking portion 13, or the brush portion 12 may include only the working section 121 without the connecting section 122, or may limit hair to a shallower end of the brush portion 12.

It should be understood that in fig. 5 and fig. 7 to 8, the brush portion 12 and the blocking portion 13 are only one of the brush portions 10, and are not meant to be the same arrangement of each brush portion 12 and blocking portion 13 of the brush 10, and any of the other brush portions 12 and blocking portions 13 of the brush 10 may be used as desired.

As shown in fig. 2, the cleaning apparatus may further include a stand 20, the stand 20 having a dust suction port 200, both ends of the roll brush 10 being rotatably provided on the stand 20, respectively, and the working section 121 being located outside the dust suction port 200. In order to facilitate the assembly and disassembly of the roller brush, the support 20 can also be detachably arranged on the main body 30, and the roller brush 10 can be assembled and disassembled together with the support 20 by detachably arranging the support 20 on the main body 30, so that the support 20 can be conveniently removed to clean hair when needed.
