Detailed Description

The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. Furthermore, it should be understood that the detailed description and specific examples, while indicating exemplary embodiments of the invention, are given by way of illustration and explanation only, and are not intended to limit the scope of the invention. In the present application, unless otherwise specified, the use of directional terms such as "upper", "lower", "left" and "right" generally refer to upper, lower, left and right in the actual use or operation of the device, and specifically to the orientation of the drawing figures.

The present application provides a roll brush assembly and a cleaning device, each of which is described in detail below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments of the present application. In the following embodiments, the descriptions of the respective embodiments have respective emphasis, and reference may be made to related descriptions of other embodiments for parts that are not described in detail in a certain embodiment.

In the prior art, cleaning apparatuses generally perform cleaning work using a roll brush. However, the drum brush is liable to entangle a large amount of hair during cleaning, resulting in a decrease in the cleaning ability of the drum brush. Too much hair twines at the round brush both ends can trigger the warning, often needs the manual intervention at this moment to clear up the hair of twining on the round brush. Particularly, in the process of manually cleaning the hair, the hair at a local position is difficult to clean, and the hair needs to be cleaned by a special cleaning tool, so that the hair is extremely inconvenient to manually clean.

In addition, in the prior art, a cutter for cutting hair is built in a rolling brush of the cleaning device, and the hair is cut by the cutter so as to be convenient to clean and recycle. When the rolling brush rotates, the cutter cuts the hair wound on the rolling brush to cut the longer hair into shorter fragments to be recovered into the dust box. Although hair can be effectively cut by the cutter arranged in the rolling brush, the cutter arranged in the rolling brush can reduce the number of leather strips or wool strips allowed to be arranged on the rolling brush, and the cleaning efficiency and the dust collection efficiency of the rolling brush are influenced. And, the cutter rotates with the round brush, and the cutter is easy to cut a carpet and the like of a user.

In view of the above, embodiments of the present disclosure provide a roller brush assembly and a cleaning device, which can solve the technical problems of the prior art that the cleaning efficiency of a cleaning device is low and a cutter is easy to cut a carpet of a user, and are described in detail below.

Referring to fig. 1 and fig. 2, fig. 1 is an exploded view of an embodiment of a cleaning device of the present application, and fig. 2 is a cross-sectional view of an embodiment of a roller brush assembly of the present application.

In one embodiment, the cleaning device may be a cleaning robot or the like having a cleaning function of washing, sweeping, mopping or the like, and the cleaning device can automatically move on the surface to be cleaned to perform a cleaning operation on the surface to be cleaned. Of course, the cleaning device may also be a handheld floor washing machine or the like having a floor washing function, a floor sweeping function, a floor mopping function, and the like, and a user can push the cleaning device to move on the surface to be cleaned by holding the cleaning device by hand to perform a cleaning operation on the surface to be cleaned, which is not limited herein. The following description is given by way of example, and not limitation, of the cleaning device being a cleaning robot. The surface to be cleaned can be the ground, or the surface to be cleaned of an object, etc.

The cleaning device includes a housing assembly 30. The housing assembly 30 serves as a base carrier of the cleaning device, and plays a role in carrying and protecting other parts of the cleaning device.

The cleaning device further comprises a roller brush assembly 10. The rolling brush assembly 10 cleans the surface to be cleaned through the rotation of itself. Specifically, the roll brush assembly 10 includes a roll brush body 11 and a cleaning bar 12. The rolling brush body 11 is provided in the housing assembly 30 and is rotatable about the first axis M. The rolling brush body 11 is rotatable around the first axis M. The cleaning strip 12 is arranged on the rolling brush body 11, and the cleaning strip 12 is used for cleaning the surface to be cleaned along with the rotation of the rolling brush body 11.

Alternatively, the cleaning strip 12 may be at least one of a leather strip and a wool strip.

The cleaning device further comprises a cutting tool assembly 20. The cutter assembly 20 is used to cut the entanglement, such as hair, etc., wound on the drum brush assembly 10. Specifically, the cutter assembly 20 is disposed in the housing assembly 30 and is rotatable about the second axis N. The cutter assembly 20 is specifically capable of rotating about the second axis N, and the cutter assembly 20 is specifically for cutting the winding wound on the sweep bar 12.

It should be noted that, the cutting tool assembly 20 of the present embodiment is located outside the roller brush body 11, and different from the design of the built-in tool of the roller brush in the prior art, the present embodiment can avoid the cutting tool assembly 20 from affecting the design of the cleaning strips 12 on the roller brush body 11, that is, the number of the cleaning strips 12 allowed to be set on the roller brush body 11 is avoided as much as possible, which is beneficial to ensuring the cleaning efficiency. In addition, in the process of cleaning the surface to be cleaned by the rolling brush assembly 10, the cutting tool assembly 20 is not easy to cut the carpet of the user, and the use experience of the user is improved.

Moreover, in the present embodiment, just because the cutting tool assembly 20 is located outside the roller brush body 11, in order to avoid the cleaning strip 12 interfering with the cutting tool assembly 20 when the roller brush body 11 rotates, the roller brush body 11 and the cutting tool assembly 20 are configured to rotate synchronously, that is, the roller brush body 11 and the cutting tool assembly 20 maintain the same rotation speed, and the rotation direction of the roller brush body 11 is opposite to the rotation direction of the cutting tool assembly 20. In this way, in the rotation process of the rolling brush body 11 and the cutting tool assembly 20, the risk of interference between the cleaning strip 12 and the cutting tool assembly 20 can be reduced as much as possible, that is, the cleaning strip 12 is prevented from colliding and beating against the cutting tool assembly 20, so that the risk of cutting the cleaning strip 12 by the cutting tool assembly 20 can be reduced, and the noise caused by interference between the cleaning strip 12 and the cutting tool assembly 20 can be reduced.

If the cutting tool assembly 20 does not rotate synchronously with the rolling brush body 11, or the rotation direction of the rolling brush body 11 is the same as the rotation direction of the cutting tool assembly 20, it is inevitable that the cleaning bar 12 collides and beats with the rotation of the rolling brush body 11, the cutting tool assembly 20 is likely to cut the cleaning bar 12, and the cleaning bar 12 collides and beats with the cutting tool assembly 20 to generate a serious noise.

In one embodiment, the cleaning device further comprises a linkage gear box 40, the linkage gear box 40 is respectively connected with the rolling brush body 11 and the cutting tool assembly 20 in a transmission manner, and the linkage gear box 40 is used for driving the rolling brush body 11 and the cutting tool assembly 20 to synchronously rotate. The linkage gear box 40 may use a motor as a power source and realize linkage between the rolling brush body 11 and the cutter assembly 20 through a gear system, i.e. drive the rolling brush body 11 and the cutter assembly 20 to rotate synchronously.

Of course, in other embodiments of the present application, the rotation between the rolling brush body 11 and the cutter assembly 20 is not limited to synchronous rotation through linkage. For example, the rolling brush body 11 and the cutting tool assembly 20 may be independent of each other, that is, the rolling brush body 11 and the cutting tool assembly 20 are driven to rotate separately, and the same rotation speed is maintained between the rolling brush body 11 and the cutting tool assembly 20 to achieve synchronous rotation, which is not limited herein.

In one embodiment, the rolling brush assembly 10 includes at least one group of the cleaning strip combinations, i.e., the cleaning strips 12 on the rolling brush body 11 are divided into at least one group of the cleaning strip combinations. Each set of the cleaning strip combination includes a first cleaning strip (e.g., first cleaning strip 121a, first cleaning strip 121 b) and a second cleaning strip (e.g., second cleaning strip 122a, second cleaning strip 122 b). The first and second cleaning strips are spaced apart from each other in the circumferential direction of the roller brush body 11 such that a cutting area 126 is formed between the first and second cleaning strips. The cutter assembly 20 is rotated to cut the wraps wound on the first and second cleaning strips in the cutting region 126.

In this way, the present embodiment is advantageous to arrange the cutter assembly 20 not to interfere with the cleaning strip 12 by arranging the cleaning strip combination to define the cutting area 126 for the cutter assembly 20 to cut the winding, that is, the present embodiment arranges the cutter assembly 20 to cut the winding in the cutting area 126, so as to further reduce the risk that the cutter assembly 20 cuts the cleaning strip 12 and avoid the noise generated by the interference of the cleaning strip 12 and the cutter assembly 20.

For example, the at least one set of cleaning strip assembly includes a first cleaning strip assembly 12a and a second cleaning strip assembly 12b. The first cleaning strip combination 12a and the second cleaning strip combination 12b are spaced from each other in the circumferential direction of the roll brush body 11. Further, the first and second

cleaning bar combinations

12a and 12b are respectively located at opposite sides of the roll brush body 11. A first cut region 1261 is formed between the first cleaning strip 121a and the second cleaning strip 122a of the first cleaning strip assembly 12a, and a second cut region 1262 is formed between the first cleaning strip 121b and the second cleaning strip 122b of the second cleaning strip assembly 12b. The cutting tool assembly 20 has a first cutting end 211 and a second cutting end 212 for cutting the wrap, the first and second cutting ends 211 and 212 being spaced from each other in a circumferential direction of the cutting tool assembly 20. With the rotation of the roller brush body 11 and the cutter assembly 20, the first cutting end 211 can rotate into the first cutting region 1261 and the second cutting end 212 can rotate into the second cutting region 1262. The first sweeping bar assembly 12a is described as an example, which is only needed for discussion and not limiting.

Specifically, an end of the first cleaning bar 121a facing away from the rolling brush body 11 is a first cleaning end 123, and an end of the second cleaning bar 122a facing away from the rolling brush body 11 is a second cleaning end 124. The distance from the first cleaning end 123 to the first axis M is equal to the distance from the second cleaning end 124 to the first axis M. The first cleaning strip 121a rotates with the roller body 11 to make the first cleaning end 123 have a first movement track G1, and the second cleaning strip 122a rotates with the roller body 11 to make the second cleaning end 124 have a first movement track G1, that is, the movement track of the first cleaning end 123 and the movement track of the second cleaning end 124 in this embodiment coincide.

It should be noted that the first cut region 1261 formed between the first cleaning strip 121a and the second cleaning strip 122a should be understood as a region formed by the first cleaning strip 121a, the second cleaning strip 122a and the first motion path G1 cooperatively enclosing each other.

The cutting tool assembly 20 has an end for cutting the wrap, which is a first cutting end 211. The cutter assembly 20 cuts the wraps wound on the first and

second cleaning strips

121a and 122a through the first cutting end 211. Wherein the first cutting end 211 has a second movement path G2 with the rotation of the cutting tool assembly 20.

The first and second movement trajectories G1 and G2 have the first intersection point O1, which means that the first cutting end 211 of the cutter assembly 20 can be inserted into the area defined by the first movement trajectory G1, that is, the first cutting end 211 of the cutter assembly 20 can be inserted into the first cutting area 1261, which can ensure that the cutter assembly 20 can effectively cut the windings wound on the first and second cleaning strips 121a and 122 a.

As the rolling brush body 11 and the cutter unit 20 rotate, the first cleaning end 123, the first cutting end 211 and the second cleaning end 124 sequentially pass through the first intersection O1, so that the first cutting end 211 rotates into the first cutting region 1261, and the first cutting end 211 can be prevented from interfering with the first cleaning strip 121a and the second cleaning strip 122a, that is, the first cutting end 211 of the cutter unit 20 can be prevented from cutting the first cleaning strip 121a and the second cleaning strip 122a, and the first cleaning strip 121a and the second cleaning strip 122a can be prevented from interfering with the cutter unit 20 to generate noise. Correspondingly, the first motion trajectory G1 and the second motion trajectory G2 also have a second intersection O2. The first cleaning end 123, the first cutting end 211 and the second cleaning end 124 sequentially pass through the second intersection point O2 as the roll brush body 11 and the cutter unit 20 rotate, so that the first cutting end 211 is rotated out of the first cutting region 1261 and the first cleaning bar 211 a is prevented from interfering with the first cleaning bar 121a and the second cleaning bar 122 a.

Further, the first cleaning end 123 and the first axis M have a first vertical line segment C1, i.e., the first cleaning end 123 forms a first vertical line segment C1 perpendicular to the first axis M. The second cleaning end 124 has a second vertical line segment C2 with the first axis M, i.e. the second cleaning end 124 makes the second vertical line segment C2 perpendicular to the first axis M. The first intersection O1 and the first axis M have a third vertical line segment C3, i.e., the first intersection O1 is a third vertical line segment C3 perpendicular to the first axis M. The first cutting end 211 and the second axis N have a fourth perpendicular segment C4, i.e., the first cutting end 211 forms the fourth perpendicular segment C4 perpendicular to the second axis N. The first intersection O1 and the second axis N have a fifth vertical line segment C5, i.e., the first intersection O1 is taken as the fifth vertical line segment C5 perpendicular to the second axis N.

When the first cutting end 211 is not rotated into the corresponding first cutting region 1261, and the extension line of the fourth vertical line segment C4 bisects the included angle θ 1 formed by the first vertical line segment C1 and the second vertical line segment C2, the included angle θ 2 formed by the first vertical line segment C1 and the third vertical line segment C3 is smaller than the included angle θ 3 formed by the fourth vertical line segment C4 and the fifth vertical line segment C5, and the included angle θ 4 formed by the second vertical line segment C2 and the third vertical line segment C3 is larger than the included angle θ 3 formed by the fourth vertical line segment C4 and the fifth vertical line segment C5, so that the first cleaning end 123, the first cutting end 211, and the second cleaning end 124 sequentially pass through the first intersection point O1, that is, the first cutting end 211 is rotated into the first cutting region 1261 without interference, and further the first cleaning end 123, the first cutting end 211, and the second cleaning end 124 sequentially pass through the second intersection point O2, that is, the first cutting end 211 is rotated out of the first cutting region 1261 without interference.

For example, when the first cutting end 211 is not rotated into the corresponding first cutting region 1261, and the extension line of the fourth vertical line segment C4 bisects the included angle θ 1 formed by the first vertical line segment C1 and the second vertical line segment C2, the included angle θ 2 formed by the first vertical line segment C1 and the third vertical line segment C3 may be about 132 °, the included angle θ 3 formed by the fourth vertical line segment C4 and the fifth vertical line segment C5 may be about 146 °, so that the first cleaning end 123 passes through the first intersection O1 first relative to the first cutting end 211, the first cleaning end 123, the first cutting end 211, and the second cleaning end 124 sequentially pass through the first intersection O1, and the first cleaning end 123, the first cutting end 211, and the second cleaning end 124 sequentially pass through the second intersection O2.

Of course, in other embodiments of the present application, the distance from the first cleaning end 123 to the first axis M may also be different from the distance from the second cleaning end 124 to the first axis M, that is, the movement locus of the first cleaning end 123 and the movement locus of the second cleaning end 124 are not coincident. At this time, the first cleaning end 123 is ensured to pass through the intersection point of the motion track of the first cleaning end 123 and the second motion track G2 before the first cutting end 211, and the second cleaning end 124 is ensured to pass through the intersection point of the motion track of the second cleaning end 124 and the second motion track G2 after the first cutting end 211, so that the first cutting end 211 can be transferred into the first cutting area 1261 without interference and transferred out of the first cutting area 1261 without interference.

The rolling brush unit 10 is not limited to the two cleaning strip combinations including the first cleaning strip combination 12a and the second cleaning strip combination 12b, and for example, the rolling brush unit 10 may include one cleaning strip combination or two or more cleaning strip combinations, and the plurality of cleaning strip combinations may be sequentially disposed at intervals in the circumferential direction of the rolling brush body 11. Correspondingly, the cutting tool assembly 20 has a corresponding number of cutting ends 21. Each group of sweeping strip combination and the motion condition of the cutting end 21 corresponding to the sweeping strip combination all satisfy the above-mentioned matching relationship, that is, each cutting end 21 can be transferred into the corresponding cutting area 126 or transferred out of the corresponding cutting area 126 without interference.

In an embodiment, based on the situation that the cleaning strips 12 described in the above embodiments may be leather strips or wool strips, the embodiment considers that the leather strips can better support the winding objects than the wool strips so as to facilitate the cutting of the cutting tool assembly 20, and therefore, it is preferable that the first cleaning strip and the second cleaning strip are both leather strips, and the first cleaning strip and the second cleaning strip can cooperate to support the winding objects so as to facilitate the cutting tool assembly 20 to cut, which is beneficial to ensure that the cutting tool assembly 20 can effectively cut the winding objects wound on the first cleaning strip and the second cleaning strip.

In an embodiment, the cutting tool assembly 20 is located on the side of the rolling brush body 11 facing away from the surface 50 to be cleaned, so that the cutting tool assembly 20 is as far away from the surface 50 to be cleaned as possible, further reducing the risk of the cutting tool assembly 20 cutting a long felt fabric such as a carpet.

Referring to fig. 3 and 4 together, fig. 3 is a schematic structural view of an embodiment of the cutting tool assembly of the present application, and fig. 4 is a schematic structural view of a region a of the cutting tool assembly shown in fig. 3.

In one embodiment, the end of the cutting tool assembly 20 used to cut the wrap has cutting teeth 25, i.e., the cutting end 21 (first cutting end 211 and second cutting end 212) described above has cutting teeth 25. The blade teeth 25 are used to cut the windings wound on the cleaning strip 12. The maximum depth S of the cutting tool assembly 20 into the cutting region 126 is greater than or equal to the height H of the cutting teeth 25, i.e., the maximum depth of the cutting tool assembly 20 into the region defined by the first motion profile G1 is greater than or equal to the height H of the cutting teeth 25. Wherein the height H of the blade tooth 25 is to be understood as the length of the blade tooth 25 in the direction towards its corresponding cutting end 21. Fig. 4 exemplarily illustrates the first cutting end 211 having the tooth 25, and the height H of the tooth 25 should be understood as the length of the tooth 25 in the direction toward the first cutting end 211.

In this way, the cutting tool assembly 20 is embedded into the cutting region 126 to a sufficient depth, so that the blade teeth 25 at the end of the cutting tool assembly 20 can efficiently cut the entanglement wound on the cleaning strip 12, and the cutting efficiency and effect of the entanglement can be improved.

Referring to fig. 5 to 7 together, fig. 5 is an exploded view of the cutting blade assembly shown in fig. 3, fig. 6 is a view illustrating an embodiment of a cleaning apparatus according to the present application, and fig. 7 is a view illustrating a region B of the cleaning apparatus shown in fig. 6.

In one embodiment, the cutting tool assembly 20 includes a stationary blade 22, a movable blade 23, and a drive mechanism 24. The outer edge of the fixed blade 22 is provided with first edge teeth 25a, and the outer edge of the movable blade 23 is provided with second edge teeth 25b. The driving mechanism 24 is in transmission connection with the movable knife 23 and is used for driving the movable knife 23 to move relative to the fixed knife 22, so that the first edge teeth 25a of the fixed knife 22 and the second edge teeth 25b of the movable knife 23 are matched to cut the wound. The driving mechanism 24 drives the movable blade 23 to move along the second axis N.

The first edge teeth 25a of the fixed blade 22 and the second edge teeth 25b of the movable blade 23 cooperate to form the cutting end 21 as explained in the above embodiments. For the case where the cutting tool assembly 20 has the first and second cutting ends 211 and 212 as set forth in the above embodiment, both side outer edges of the stationary blade 22 have the first edge teeth 25a, and both side outer edges of the movable blade 23 have the second edge teeth 25b. The first blade tooth 25a and the second blade tooth 25b on the same side of the fixed blade 22 and the movable blade 23 are respectively matched to form a first cutting end 211 and a second cutting end 212.

Further, the driving mechanism 24 includes a moving bracket 241, a moving blade driving member 242, and a cam 243. The moving bracket 241 is fixedly connected with the moving blade 23. Specifically, the cutting tool assembly 20 further includes a left tool cover 291 and a right tool cover 292, the left tool cover 291 is disposed at one end of the fixed blade 22 and the movable blade 23, and the right tool cover 292 is disposed at the other end of the fixed blade 22 and the movable blade 23. The moving bracket 241 is fixedly connected with the moving knife 23 through a left knife end cover 291 or a right knife end cover 292. The moving bracket 241 is provided with a transmission groove 244. The movable knife driving member 242 is in transmission connection with the cam 243, and the cam 243 is embedded in the transmission groove 244. The cam 243 may be an eccentric wheel or the like. The movable blade driving member 242 is used for driving the cam 243 to rotate, so that the cam 243 drives the moving bracket 241 to reciprocate through the transmission groove 244, so as to drive the movable blade 23 to reciprocate along the second axis N relative to the fixed blade 22, and further realize efficient cutting of the winding on the cleaning strip 12.

Further, the cutting tool assembly 20 also includes a tool holder 26. The tool holder 26 is provided with a receiving cavity for receiving the stationary blade 22 and the movable blade 23. Specifically, tool holder 26 includes a first sub-seat 261 and a second sub-seat 262, and first sub-seat 261 and second sub-seat 262 are butted to form a receiving cavity. The first sub-base 261 is disposed adjacent to the stationary blade 22, and the second sub-base 262 is disposed adjacent to the movable blade 23.

The cutting tool assembly 20 further comprises a resilient member 27. The elastic member 27 is disposed on the knife holder 26, and the elastic member 27 tightly attaches the movable knife 23 to the fixed knife 22, so that the fixed knife 22 and the movable knife 23 can efficiently cut the wound, which is beneficial to improving the cutting effect. In view of the fixed relative position of the fixed blade 22 in the tool seat 26, it is preferable that the elastic member 27 is disposed on the second sub-seat 262, i.e. the elastic member 27 tightly contacts the movable blade 23 to the fixed blade 22 from the side of the movable blade 23 away from the fixed blade 22.

Alternatively, the elastic member 27 may be a spring plate, etc., and is not limited herein.

Further, the cutting tool assembly 20 also comprises a rolling bearing 28. Specifically, the rolling bearing 28 may be provided to the second sub-seat 262. The movable blade 23 is provided with a rolling groove 231, and the rolling bearing 28 is embedded in the rolling groove 231 and is in rolling contact with the groove wall of the rolling groove 231. In this way, in the process that the movable blade 23 moves relative to the fixed blade 22, the rolling bearing 28 can reduce the frictional resistance received by the movable blade 23, so that the movable blade 23 moves more smoothly, and the cutting efficiency is further improved.

For example, the second sub-seat 262 is provided with the elastic element 27 and the rolling bearing 28 at two ends on the second axis N, respectively. The two elastic members 27 on the second sub-base 262 cooperate to tightly attach the movable blade 23 to the fixed blade 22. Moreover, two rolling grooves 231 are provided on the movable blade 23, and each rolling bearing 28 is fitted in the corresponding rolling groove 231. Also, the housing assembly 30 includes a main housing 35 and a cutter cover plate 36. The main housing 35 and the cutter cover plate 36 can be butted to form a space for accommodating the cutting cutter assembly 20. Specifically, the stationary blade 22, the movable blade 23, and the blade holder 26 are accommodated in the space, and the driving mechanism 24 is located outside the space and fixed to the main housing 35.

Referring to fig. 8 and 9 together, fig. 8 is a schematic structural diagram of an embodiment of the rolling brush assembly of the present application, and fig. 9 is a schematic sectional diagram of a cleaning device of the present application.

In one embodiment, the roller brush assembly 10 further includes a roller brush end cap 13. The rolling brush end cover 13 is provided at an end of the rolling brush body 11. The end of the cleaning strip 12 facing the rolling brush end cover 13 is provided with a gathering groove 125, the groove bottom of the gathering groove 125 is close to the rolling brush body 11 relative to the outer circumferential surface of the rolling brush end cover 13, and the cutting tool assembly 20 can cut the winding in the gathering groove 125.

Specifically, the collection groove 125 extends along the first axis M and penetrates the cleaning bar 12 toward the corresponding brush end cap 13 and in a direction away from the brush body 11. The first cleaning strip and/or the second cleaning strip is/are provided with collecting grooves 125, i.e. the end of the first cleaning strip facing the roller cover 13 is provided with collecting grooves 125, and/or the end of the second cleaning strip facing the roller cover 13 is provided with collecting grooves 125. The outer circumferential surface of the roller-brush end cap 13 is to be understood as the outer surface of the roller-brush end cap 13 which is arranged about the first axis M. The groove bottom of the collecting groove 125 is close to the rolling brush body 11 relative to the outer circumferential surface of the rolling brush end cover 13, that is, the groove bottom of the collecting groove 125 is lower than the outer circumferential surface of the rolling brush end cover 13, so that the winding wound on the rolling brush end cover 13 is easily collected in the collecting groove 125, and the winding wound on the rolling brush end cover 13 can be reduced. And, the entanglement that assembles in gathering groove 125 can be cut by cutter assembly 20, therefore this embodiment can make on the round brush subassembly 10 most entanglement can accept cutter assembly 20 cutting, and then be convenient for clear up, retrieve the entanglement on the round brush subassembly 10, further be favorable to guaranteeing clean efficiency.

Further, a portion of the teeth 25 of the cutting tool assembly 20 is disposed corresponding to the collection groove 125, i.e., the portion of the teeth 25 of the cutting tool assembly 20 is capable of cutting the entanglement in the collection groove 125. In other words, the cutting blade teeth 25 of the end of the cutter assembly 20 facing the brush end cap 13 are covered to the collection groove 125 so that the cutter assembly 20 can cut the windings in the collection groove 125, as shown in fig. 9.

And, when the cutting tool assembly 20 rotates into the cutting region 126, the minimum distance from the cutting end 21 of the cutting tool assembly 20 to the first axis M is smaller than the distance from the groove bottom of the collecting groove 125 to the first axis M, so as to ensure that the cutting tool assembly 20 can normally cut the winding wound on the groove bottom of the collecting groove 125.

Further, the outer circumferential surface of the roll brush cover 13 has a guide surface 131 inclined toward the roll brush body 11, and the guide surface 131 serves to guide the entanglement on the roll brush cover 13 to be gathered in the gathering groove 125. The guide surface 131 is located on the side of the roller cover 13 facing the cleaning strip 12, and when the winding is wound around the guide surface 131 of the roller cover 13, the winding moves toward the collecting groove 125 under the guidance of the guide surface 131 and is collected in the collecting groove 125.

Alternatively, the guide surface 131 may be necked toward the cleaning strip 12 to form a taper such that the guide surface 131 is inclined toward the roll brush body 11, and the inclined guide surface 131 can guide the entanglement toward the accumulation groove 125 to be gathered to the accumulation groove 125.

For example, the two ends of the rolling brush body 11 on the first axis M are respectively provided with a rolling brush end cover 13. Each of the roll brush caps 13 has a guide surface 131 on a side facing the first and second cleaning strips. The first cleaning bar has collecting grooves 125 at both ends thereof on the first axis M, respectively, and the second cleaning bar also has collecting grooves 125 at both ends thereof on the first axis M, respectively. The blade teeth 25 of the cutter assembly 20 cover the collection grooves 125 to both ends of the first cleaning bar and also cover the collection grooves 125 to both ends of the second cleaning bar.

Referring to fig. 10, fig. 10 is a schematic structural view of a region C of the cleaning apparatus shown in fig. 9.

In one embodiment, when the roller brush assembly 10 is assembled to the housing assembly 30, the roller brush end cover 13 abuts against the housing assembly 30, that is, only a very small assembly gap is provided between the roller brush end cover 13 and the housing assembly 30, and the winding object can be limited from passing between the roller brush end cover 13 and the housing assembly 30 and being wound on the side of the roller brush end cover 13 away from the cleaning strip 12. Because the cutting tool assembly 20 is located at the side of the rolling brush end cover 13 facing the cleaning strip 12, if the winding is wound at the side of the rolling brush end cover 13 facing away from the cleaning strip 12, the winding cannot be cut by the cutting tool assembly 20, and then the rolling brush assembly 10 is wound by too much winding, and the winding at this position is difficult to be manually cleaned.

Specifically, the housing assembly 30 further includes a roller brush cover 37. The main housing 35 and the roller brush cover 37 can be butted to form a space for accommodating the roller brush assembly 10. The rolling brush end cover 13 of the present embodiment abuts against the rolling brush cover plate 37, that is, only a very small assembly gap is provided between the rolling brush end cover 13 and the rolling brush cover plate 37, and the object to be wound can be limited from passing between the rolling brush end cover 13 and the rolling brush cover plate 37 and being wound on the side of the rolling brush end cover 13 away from the cleaning strip 12.

Further, the brush roll cover 37 and the cutter cover 36 are respectively located on different sides of the main housing 35. Fig. 1 exemplarily shows that the cutter cover plate 36 is on the upper side of the main housing 35, and the roll brush cover plate 37 is on the lower side of the main housing 35.

Referring to fig. 11, fig. 11 is a schematic view of another embodiment of a cross-sectional structure of a cleaning device according to the present application.

In one embodiment, the housing assembly 30 defines a dust suction opening 31 facing the roller brush assembly 10. Specifically, the dust suction port 31 is connected to a dust box (not shown) of the cleaning device, and the dust suction port 31 is used for recovering dirt of a surface to be cleaned. The round brush assembly 10 cleans the surface to be cleaned, and collects dirt of the surface to be cleaned into the dust box through the dust suction port 31. Further, the housing assembly 30 further includes a soft rubber air channel 311. The soft air channel member 311 is disposed on the main housing 35, and the soft air channel member 311 encloses to form the dust suction opening 31, as shown in fig. 1, 6 and 11.

The housing assembly 30 also has comb teeth 32 disposed opposite the suction opening 31. Further, comb teeth 32 may be provided to the main housing 35, and the comb teeth 32 are located in a space formed by the abutting of the main housing 35 and the roller brush cover 37. The rolling brush body 11 drives the cleaning strip 12 to rotate towards the comb teeth 32, so that the comb teeth 32 can peel off the winding on the cleaning strip 12, and the dust collection opening 31 is at least used for recovering the winding peeled off by the comb teeth 32.

In this way, the comb teeth 32 are hook-shaped. In the process of rotating the rolling brush assembly 10, the rolling brush body 11 drives the cleaning strip 12 to clean the surface to be cleaned, and the cutting tool assembly 20 cuts the winding materials wound on the cleaning strip 12. The rolling brush body 11 drives the cleaning strip 12 to rotate towards the comb teeth 32, when the cleaning strip 12 passes through the comb teeth 32, the comb teeth 32 can peel off the winding objects which are cut into the fragments on the cleaning strip 12, and the winding objects peeled off by the comb teeth 32 can be recovered by the dust suction opening 31. Moreover, the comb teeth 32 of the present embodiment are disposed opposite to the dust suction opening 31, so that the entanglement peeled off by the comb teeth 32 can be immediately collected by the dust suction opening 31, so as to facilitate the collection of the entanglement.

Further, the cleaning strip 12 of the roll brush assembly 10 further includes a third cleaning strip 127. For the case that the first cleaning strip and the second cleaning strip are leather strips, the third cleaning strip 127 can be wool strips, and the first cleaning strip, the second cleaning strip and the third cleaning strip 127 are sequentially distributed at intervals along the circumferential direction of the rolling brush body 11.

For example, two third cleaning strips 127 are disposed on the rolling brush body 11, the two third cleaning strips 127 are respectively disposed on two opposite sides of the rolling brush body 11, one of the third cleaning strips 127 is disposed on one side of the first cleaning strip combination 12a and the second cleaning strip combination 12b, and the other third cleaning strip 127 is disposed on the other side of the first cleaning strip combination 12a and the second cleaning strip combination 12b. Of course, in other embodiments of the present application, the number of the third cleaning bars 127 may also be one or more than two, which is not limited herein.

The third cleaning bar 127 rotates with the rolling brush body 11 so that the end of the third cleaning bar 127 facing away from the rolling brush body 11 has a third movement locus G3. The height of the third cleaning strip 127 is higher than the heights of the first cleaning strip and the second cleaning strip, that is, the distance from the end of the third cleaning strip 127 away from the rolling brush body 11 to the first axis M is greater than the distance from the end of the first cleaning strip away from the rolling brush body 11 to the first axis M and the distance from the end of the second cleaning strip away from the rolling brush body 11 to the first axis M. In other words, the first movement locus G1 of the present embodiment is close to the roller brush body 11 with respect to the third movement locus G3.

At least a part of the comb teeth 32 of the present embodiment is located between the first motion trajectory G1 and the third motion trajectory G3. In other words, at least a portion of the comb teeth 32 is embedded in the area defined by the third motion trajectory G3, but the at least a portion of the comb teeth 32 is not embedded in the area defined by the first motion trajectory G1. In this way, the third cleaning strip 127 passes through the comb teeth 32 during the rotation of the rolling brush body 11, so that the comb teeth 32 can peel off the entanglement on the third cleaning strip 127, and the first cleaning strip and the second cleaning strip do not interfere with the comb teeth 32, thereby preventing the first cleaning strip and the second cleaning strip from colliding with each other and beating the comb teeth 32 to generate noise.

It should be noted that, since the third cleaning strip 127 is made of wool tops, after the winding material wound on the rolling brush assembly 10 is cut into pieces by the cutter assembly 20, when the third cleaning strip 127 passes through the comb teeth 32, the comb teeth 32 can easily peel off the cut winding material, and the winding material can be smoothly recovered by the dust suction opening 31. Also, the third cleaning bar 127 does not generate significant noise even if it interferes with the comb teeth 32. The first strip and the second of cleaning clean the strip for the leather strap, if the first strip and the second of cleaning clean the strip and interfere with broach 32, can lead to the first strip and the second of cleaning clean the strip collision, pat broach 32 and produce the noise.

Referring to fig. 12 and 13 together, fig. 12 is a schematic bottom view of the cleaning device shown in fig. 6, and fig. 13 is a schematic structural view of a region D of the cleaning device shown in fig. 12.

In one embodiment, the housing assembly 30 defines a cleaning area 33 exposing the roller brush assembly 10, and the sweeping strip 12 sweeps the surface to be cleaned through the cleaning area 33. The casing assembly 30 is further provided with a scraping strip 34, and the scraping strip 34 is used for enabling the cleaning area 33 to form a negative pressure environment, so that the dust collection effect is improved. Specifically, the cleaning zone 33 is opened to the roller brush cover plate 37, and the wiper strip 34 is provided to the roller brush cover plate 37. Also, the length L of the wiper strip 34 is greater than the length U of the cleaning zone 33, which reduces the risk of the fitting gap between the wiper strip 34 and the roller cover 37 catching hairs. Here, the length L of the wiper strip 34 should be understood as the length of the wiper strip 34 on the first axis M, and similarly, the length U of the cleaning zone 33 should be understood as the length of the cleaning zone 33 on the first axis M.

In the present embodiment, the length L of the scraper bar 34 is greater than the length U of the cleaning area 33, that is, both ends of the scraper bar 34 on the first axis M extend outwards properly, so that the assembly gap J (as shown in fig. 13) between the scraper bar 34 and the roller cover plate 37, which is directly connected to the cleaning area 33, extends along the first axis M, and the difficulty of the hairs being caught in the assembly gap J can be improved. In addition, in the present embodiment, the fitting gap between the wiper strip 34 and the roller cover 37 has a zigzag, meandering labyrinth shape, and the risk of hair being caught in the fitting gap between the wiper strip 34 and the roller cover 37 can be reduced. Whereas in the prior art the length of the wiper strip is usually equal to the length of the cleaning zone, so that the assembly gap between the wiper strip and the roller cover plate, which directly connects the cleaning zone, extends in a direction perpendicular to the first axis, which would inevitably lead to hairs being easily caught in the assembly gap between the wiper strip and the roller cover plate.

In one embodiment, the roller brush assembly includes a roller brush assembly 10 and a cutter assembly 20. The roll brush assembly 10 includes a roll brush body 11 and a cleaning bar 12. The rolling brush body 11 is rotatable about a first axis M. The cleaning strip 12 is arranged on the rolling brush body 11, and the cleaning strip 12 is used for cleaning the surface to be cleaned along with the rotation of the rolling brush body 11. The cutter assembly 20 is used to cut the wrap wound on the sweep bar 12.

The cutting tool assembly 20 is located outside the rolling brush body 11, so that the cutting tool assembly 20 can be prevented from influencing the design of the cleaning strips 12 on the rolling brush body 11, namely, the number of the cleaning strips 12 allowed to be arranged on the rolling brush body 11 is prevented from being influenced as much as possible, and the cleaning efficiency is favorably ensured. In addition, in the process of cleaning the surface to be cleaned by the rolling brush assembly 10, the carpet of the user is not easily cut by the cutting tool assembly 20, which is beneficial to improving the use experience of the user.

Moreover, since the cutting tool assembly 20 is located outside the roller brush body 11, in order to prevent the cleaning strip 12 from interfering with the cutting tool assembly 20 when the roller brush body 11 rotates, the cutting tool assembly 20 is further movably disposed relative to the roller brush body 11 so as to avoid the cleaning strip 12 when the cleaning strip 12 rotates along with the roller brush body 11. In this way, the risk of interference between the cleaning strip 12 and the cutter assembly 20 can be reduced as much as possible, that is, the cleaning strip 12 can be prevented from colliding with and beating the cutter assembly 20, so that the risk of the cutter assembly 20 cutting the cleaning strip 12 can be reduced, and the noise caused by interference between the cleaning strip 12 and the cutter assembly 20 can be reduced.

It should be noted that the cutting tool assembly 20 of the present embodiment is movably disposed relative to the rolling brush body 11, and the rolling brush body 11 and the cutting tool assembly 20 explained in the above embodiments can rotate synchronously and rotate in opposite directions; alternatively, the cutter assembly 20 may be movably disposed with respect to the roller brush body 11, when the cleaning bar 12 approaches the cutter assembly 20 as the roller brush body 11 rotates, the cutter assembly 20 moves in a direction away from the roller brush body 11 to avoid the cleaning bar 12, and when the cleaning bar 12 moves away from the cutter assembly 20 as the roller brush body 11 rotates, the cutter assembly 20 moves toward the roller brush body 11 to cut the winding wound on the cleaning bar 12; alternatively, the cutters (i.e. the fixed cutter 22 and the movable cutter 23) in the cutter assembly 20 are of a telescopic design, when the cleaning bar 12 approaches the cutter assembly 20 along with the rotation of the rolling brush body 11, the cutters in the cutter assembly 20 retract to avoid the cleaning bar 12, and when the cleaning bar 12 moves away from the cutter assembly 20 along with the rotation of the rolling brush body 11, the cutters in the cutter assembly 20 extend to cut the winding on the cleaning bar 12.

The technical solution provided in the embodiments of the present application is described below with reference to specific application scenarios.

The application scene one:

the cleaning device is in particular a cleaning robot. The cleaning device comprises a shell assembly 30, and a rolling brush assembly 10 and a cutting tool assembly 20 which are arranged on the shell assembly 30. The roll brush assembly 10 includes a roll brush body 11 and a cleaning bar 12. The cleaning strip 12 is arranged on the rolling brush body 11, and the cleaning strip 12 is used for cleaning the surface to be cleaned along with the rotation of the rolling brush body 11. The cutter assembly 20 is used to cut the wrap wound on the sweep bar 12.

Moreover, since the cutter assembly 20 is located outside the roller brush body 11, in order to prevent the cleaning strip 12 from interfering with the cutter assembly 20 due to the rotation of the roller brush body 11, the roller brush body 11 and the cutter assembly 20 are configured to rotate synchronously, and the rotation direction of the roller brush body 11 is opposite to the rotation direction of the cutter assembly 20. In this way, in the rotation process of the rolling brush body 11 and the cutting tool assembly 20, the risk of interference between the cleaning strip 12 and the cutting tool assembly 20 can be reduced as much as possible, that is, the cleaning strip 12 is prevented from colliding and beating against the cutting tool assembly 20, so that the risk of cutting the cleaning strip 12 by the cutting tool assembly 20 can be reduced, and the noise caused by interference between the cleaning strip 12 and the cutting tool assembly 20 can be reduced.

Application scenario two:

the cleaning device is in particular a cleaning robot. The cleaning device comprises a shell assembly 30, and a rolling brush assembly 10 and a cutting tool assembly 20 which are arranged on the shell assembly 30. The roll brush assembly 10 includes a roll brush body 11 and a cleaning bar 12. The rolling brush body 11 is rotatable about a first axis M. The cleaning strip 12 is arranged on the rolling brush body 11, and the cleaning strip 12 is used for cleaning the surface to be cleaned along with the rotation of the rolling brush body 11. The cutter assembly 20 is rotatable about a second axis N for cutting the wound on the cleaning strip 12.

Referring to fig. 14, fig. 14 is a schematic flow chart illustrating a control method of the cleaning apparatus according to an embodiment of the disclosure. In this application scenario, the cutter assembly 20 synchronously cuts the entanglement on the cleaning strip 12 during the cleaning of the surface to be cleaned by the roller brush assembly 10.

S101: and judging whether a cleaning request instruction is received.

The cleaning device determines whether a cleaning request command is received. If the cleaning device receives the cleaning request command, step S102 is executed, in which the cleaning device performs a cleaning operation in response to the cleaning request command. Specifically, a user inputs a cleaning request instruction to the cleaning device by directly operating on the cleaning device, so that the cleaning device performs a cleaning work in response to the cleaning request instruction; or the user sends a cleaning request instruction to the cleaning device through an application program on the mobile terminal and by means of communication media such as Bluetooth and wifi, so that the cleaning device performs cleaning work in response to the cleaning request instruction.

S102: the rolling brush body and the cutting tool component are driven to synchronously rotate, and the cutting tool component is controlled to synchronously cut the winding materials wound on the cleaning strip.

The cleaning device performs the cleaning work in response to the above-mentioned cleaning request instruction. Specifically, the cleaning device drives the rolling brush body 11 and the cutter assembly 20 to rotate synchronously, and controls the cutter assembly 20 to cut the entanglement wound on the sweep bar 12 synchronously.

Application scenario three:

the cleaning device is specifically a cleaning robot, and the cleaning device and a base station device matched with the cleaning device work cooperatively. The cleaning device comprises a shell assembly 30, and a rolling brush assembly 10 and a cutting tool assembly 20 which are arranged on the shell assembly 30. The roll brush assembly 10 includes a roll brush body 11 and a cleaning bar 12. The rolling brush body 11 is rotatable about a first axis M. The cleaning strip 12 is arranged on the rolling brush body 11, and the cleaning strip 12 is used for cleaning the surface to be cleaned along with the rotation of the rolling brush body 11. The cutter assembly 20 is rotatable about a second axis N for cutting the wound on the cleaning strip 12.

Referring to fig. 15, fig. 15 is a schematic flow chart illustrating a control method of a cleaning apparatus according to another embodiment of the present application. In this application scenario, the cutter assembly 20 does not synchronously cut the winding on the sweeping bar 12 during the process of sweeping the surface to be cleaned by the rolling brush assembly 10.

S201: and judging whether a cleaning request instruction is received.

The cleaning device determines whether a cleaning request command is received. If the cleaning device receives the cleaning request command, step S202 is executed, in which the cleaning device performs a cleaning operation in response to the cleaning request command. Specifically, a user inputs a cleaning request instruction to the cleaning device by directly operating on the cleaning device, so that the cleaning device performs a cleaning work in response to the cleaning request instruction; or the user sends a cleaning request instruction to the cleaning device through an application program on the mobile terminal and by means of communication media such as Bluetooth and wifi, so that the cleaning device performs cleaning work in response to the cleaning request instruction.

S202: the rolling brush body and the cutting tool assembly are driven to synchronously rotate, the cutting tool assembly does not cut the winding on the cleaning strip until the rolling brush assembly finishes the cleaning work of the surface to be cleaned, and the cutting tool assembly is controlled to cut the winding on the cleaning strip.

The cleaning device performs the cleaning work in response to the above-described cleaning request instruction. Specifically, the cleaning device drives the rolling brush body 11 and the cutting tool assembly 20 to synchronously rotate, and the cutting tool assembly 20 does not cut the winding wound on the sweeping bar 12 until the rolling brush assembly 10 finishes the cleaning work of the surface to be cleaned, and the cutting tool assembly 20 is controlled to cut the winding wound on the sweeping bar 12.

In order to further reduce the risk that the cutting tool assembly 20 cuts a long woollen fabric such as a carpet and the like in the process of cleaning the surface to be cleaned by the rolling brush assembly 10, in the application scene, the surface to be cleaned is cleaned by the rolling brush assembly 10, and after the cleaning device returns to the base station device, the cutting tool assembly 20 is controlled to cut the winding materials wound on the cleaning strip 12. The base station device can also provide larger dust absorption power so as to be convenient for recovering the fragments of the winding obtained by cutting through the cutting tool assembly 20, and the cleaning and recovering efficiency of the winding can be improved.

Specifically, during the process in which the roll brush assembly 10 cleans the surface to be cleaned, the roll brush assembly 10 and the cutter assembly 20 are rotated in synchronization, but the cutter assembly 20 does not cut the entanglement wound on the cleaning strip 12. After the rolling brush assembly 10 finishes the cleaning of the surface to be cleaned and the cleaning device returns to the base device, the fan of the base device is connected to the dust box of the cleaning device, and the cutting tool assembly 20 and the cutting area 126 are aligned by the hall sensor (i.e. the cutting tool assembly 20 is rotated into the cutting area 126 as illustrated in the above embodiment). The roll brush assembly 10 and the cutter assembly 20 are kept from rotating while the cutter assembly 20 is driven to cut the entanglement on the sweep strip 12, while the base station apparatus provides a large dust suction power to recover the entanglement fragments cut by the cutter assembly 20. For the case where the roll brush assembly 10 is provided with a plurality of cutting regions 126 (i.e., the first cutting region 1261 and the second cutting region 1262) as described in the above embodiment, the cutter assembly 20 may be driven to cut the windings on the sweep strip 12 alternately in the different cutting regions 126.

It should be noted that, the cutting tool assembly 20 is located outside the rolling brush body 11, so that the cutting tool assembly 20 can be prevented from affecting the design of the cleaning strips 12 on the rolling brush body 11, that is, the number of the cleaning strips 12 allowed to be arranged on the rolling brush body 11 is prevented from being affected as much as possible, which is beneficial to ensuring the cleaning efficiency. In addition, in the process of cleaning the surface to be cleaned by the rolling brush assembly 10, the carpet of the user is not easily cut by the cutting tool assembly 20, which is beneficial to improving the use experience of the user.

Moreover, since the cutter assembly 20 is located outside the roller brush body 11, in order to prevent the cleaning strip 12 from interfering with the cutter assembly 20 due to the rotation of the roller brush body 11, the roller brush body 11 and the cutter assembly 20 are configured to rotate synchronously, and the rotation direction of the roller brush body 11 is opposite to the rotation direction of the cutter assembly 20. In this way, during the rotation of the rolling brush body 11 and the cutting tool assembly 20, the risk of interference between the cleaning strip 12 and the cutting tool assembly 20 can be reduced as much as possible, i.e., the cleaning strip 12 is prevented from colliding against and beating the cutting tool assembly 20, so that the risk of cutting the cleaning strip 12 by the cutting tool assembly 20 can be reduced, and the noise caused by interference between the cleaning strip 12 and the cutting tool assembly 20 can be reduced.

And an application scene four:

the roller brush assembly is independent of the cleaning device. The brush roll assembly can be removably assembled with the cleaning device as a unitary system. Specifically, the roller brush assembly may be integrally assembled with or disassembled from the cleaning device.

The roller brush assembly includes a roller brush assembly 10 and a cutter assembly 20. The roll brush assembly 10 includes a roll brush body 11 and a cleaning bar 12. The rolling brush body 11 is rotatable about a first axis M. The cleaning strip 12 is arranged on the rolling brush body 11, and the cleaning strip 12 is used for cleaning the surface to be cleaned along with the rotation of the rolling brush body 11. The cutter assembly 20 is rotatable about a second axis N for cutting the wound on the cleaning strip 12.

It should be noted that the roller brush assembly 10 and the cutter assembly 20 have been described in detail in the above embodiments, and thus, they will not be described in detail herein.

The roll brush assembly and the cleaning device provided by the present application are described in detail above, and the principle and the embodiment of the present application are explained herein by applying specific examples, and the descriptions of the above examples are only used to help understand the method and the core idea of the present application; meanwhile, for a person skilled in the art, according to the idea of the present application, the specific implementation manner and the application scope may be changed, and in summary, the content of the present specification should not be construed as a limitation to the present application.
