[0002] With the gradual improvement of living standards, people's requirements for the quality of life are getting higher and higher. More and more people are laying exquisite floors or tiles on the ground of their homes. The materials of the floors are varied, such as wooden floors or stone floors. When the floors or tiles are stained with dirt and need to be cleaned, the traditional method is to use a broom, mop or trailer to clean them. This method is time-consuming and laborious, and cannot increase people's interest in cleaning work, and is not conducive to keeping the indoor environment clean. Therefore, the emergence of cleaning equipment has solved the problem of cumbersome cleaning methods for people to a certain extent. Since the entanglement on the roller brush of the cleaning equipment is easy to enter the interior of the drive assembly during operation, it is necessary to design a new roller brush to protect the drive assembly of the cleaning equipment.

[0029] In order to make the purpose, technical solutions and advantages of the present disclosure clearer, the present disclosure will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0034] It should also be noted that the term "includes", "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, so that a commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprising a ..." do not exclude the existence of other identical elements in the commodity or device including the elements.

[0035] In the related art, since there is a gap between the connecting part of the roller brush and the shell of the cleaning module, and the gap is relatively large, under normal working conditions, entangled objects such as hair can easily drill into the interior of the cleaning module along the gap between the roller brush and the shell, causing damage to the interior of the cleaning module, affecting the normal operation of the roller brush, and even causing the cleaning equipment to be unable to be used normally, affecting the user's experience.

[0036] Based on the above description, the present invention provides a roller brush for a cleaning module, comprising: a roller brush body; a connecting portion, arranged at one end of the roller brush body, configured to connect the roller brush to a driving assembly of the cleaning module; a baffle, arranged at one end of the roller brush body, configured to isolate the roller brush body from the connecting portion; a first blocking member, arranged on an outer surface of the connecting portion, when the roller brush is assembled to the driving assembly, at least a portion of the first blocking member interferes with the cleaning module to prevent entanglements from entering the driving assembly, wherein, when the roller brush is not assembled to the driving assembly, in the axial direction of the roller brush, a projected area of ​​the first blocking member is greater than a projected area of ​​the baffle.

[0037] In the roller brush, cleaning module and cleaning device provided by the present disclosure, the roller brush has a blocking piece and a first blocking member, the first blocking member is arranged on the outer surface of the connecting portion, and at least part of the first blocking member interferes with part of the cleaning module, so as to block the gap between the roller brush and the shell of the cleaning module. When the roller brush is in a normal working state, the setting of the first blocking member can prevent hair and other entanglements from drilling into the cleaning module along the gap between the roller brush and the shell, thereby preventing the internal damage of the cleaning module or affecting the normal working of the roller brush, thereby improving the user's use experience.

[0038] In view of this, optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0039] like Figure 1As shown, the embodiment of the present disclosure provides a roller brush 100 for a cleaning module 1000 of a cleaning device. The roller brush 100 comprises a roller brush body 110, a connecting portion 120, a blocking piece 130 and a first blocking member 140, wherein the first blocking member 140 is arranged on the outer surface of the connecting portion 120, at least a portion of the first blocking member 140 interferes with at least a portion of the cleaning module 1000, and is configured to prevent entanglements such as hair on the roller brush body from entering the driving assembly of the cleaning module 1000.

[0040] In some embodiments, the roller brush body 110 may be a cylindrical structure or a conical structure. Figure 1 , Figure 2 As shown, the roller brush body 110 may be a conical structure, having a first end 111 and a second end 112. In the axial direction of the roller brush 100, the radial cross-sectional area of ​​the first end 111 is greater than the radial cross-sectional area of ​​the second end 112. When the roller brush 100 rotates along the axial direction of the roller brush 100, dirt, hair and other entanglements may be entangled on the surface of the roller brush 100. Since the roller brush body 110 is a conical structure, as the roller brush 100 rotates, the entanglements entangled on the surface of the roller brush body 110 will be transported from the first end 111 toward the second end 112, preventing dirt from entering the driving component of the cleaning module 1000.

[0041] In some embodiments, in order to prevent the entangled objects on the surface of the rolling brush 100 from entering the driving assembly of the cleaning module 1000, the rolling brush 100 further includes a connecting portion 120 and a blocking piece 130. The connecting portion 120 is disposed at the first end 111 of the rolling brush body 110 and extends toward the axial direction of the rolling brush 100, and is configured to connect the rolling brush 100 with the cleaning module 1000. The blocking piece 130 is disposed at the first end 111 and extends in an annular shape toward the radial direction of the rolling brush 100. In the radial direction of the rolling brush 100, the diameter of the blocking piece 130 is greater than the diameter of the first end 111, and is configured to isolate the rolling brush body 110 from the connecting portion 120, so as to prevent the entangled objects on the rolling brush body 110 from entering the driving assembly.

[0042] Specifically, when the roller brush 100 rotates at high speed in normal working state, the dust entangled on the surface of the roller brush body 110 will be transported from the first end 111 toward the second end 112. The setting of the baffle 130 can effectively prevent the dust from entering the driving component of the cleaning module 1000.

[0043] In some embodiments, the windings on the surface of the roller brush body 110 may bypass the blocking piece 130 and move toward the direction of the connecting portion 120, so a first blocking member 140 is provided on the outer surface of the connecting portion 120. The first blocking member 140 is an annular structure, the inner diameter of which is slightly larger than the outer diameter of the connecting portion 120, and is configured to be sleeved on the outer wall of the connecting portion 120 to connect with the roller brush body 110. In response to the roller brush 100 being installed on the cleaning module 1000, at least a portion of the first blocking member 140 interferes with the cleaning module 1000, and is configured to prevent the windings on the roller brush body 110 from entering the driving assembly of the cleaning module 1000.

[0044] Specifically, before the roller brush 100 is installed on the cleaning module 1000, the roller brush 100 is in a natural state. At this time, when the first blocking member 140 is installed on the connecting portion 120, in the axial direction of the roller brush 100, the projection area of ​​the first blocking member 140 is significantly larger than the projection area of ​​the blocking piece 130.

[0045] After the first blocking member 140 is installed on the connecting portion 120, the roller brush 100 can be installed on the cleaning device. At this time, the roller brush 100 is in an installed state. In this state, since at least a portion of the first blocking member 140 contacts and interferes with a portion of the cleaning module 1000, the projection area of ​​the first blocking member 140 is substantially equal to the projection area of ​​the blocking sheet 130 in the axial direction of the roller brush 100. When the roller brush 100 is in an installed state, since at least a portion of the first blocking member 140 interferes with a portion of the cleaning module 1000, during the operation of the roller brush 100, hair and dirt entangled on the roller brush body 110 will not penetrate into the interior of the cleaning device along the gap between the connecting portion 120 and the housing 1100, thereby ensuring the safety of the roller brush 100 during operation.

[0046] In some embodiments, in the axial direction of the roller brush body 110, the width of the connecting portion 120 is H1, and the width of the first blocking member 140 is H2, where H1≥H2. That is, the width of the first blocking member 140 is not greater than the width of the connecting portion 120. On the one hand, it can prevent the first blocking member 140 from being too wide, which may affect the installation of the roller brush 100 or the installation of other structural parts inside the cleaning module 1000. On the other hand, the housing prevents part of the first blocking member 140 from being rolled into the cleaning module 1000 along the gap between the parts, causing the roller brush 100 to work poorly.

[0047] In some embodiments, the first blocking member 140 may be a relatively soft structural member such as a hair transplant or a wool strip, so that, in the working state, the normal rotation of the roller brush 100 will not be affected by the large friction force or large resistance strength generated between the first blocking member 140 and the cleaning module 1000. When the hair transplant or wool strip is installed on the connecting portion 120, the hair transplant or wool strip is substantially perpendicular to the outer surface of the connecting portion 120, so that the hair transplant or wool strip can play the maximum interference effect, and prevent the hair and other entanglements and dirt from entering the interior of the cleaning module 1000. At least part of the first blocking member 140 contacts the baffle 130, and in the axial direction of the roller brush body 110, the baffle 130 has a limiting effect on the first blocking member 140.

[0048] It should be noted that the present disclosure does not specifically limit the connection method between the first blocking member 140 and the connecting portion 120. The first blocking member 140 can be fixedly installed on the connecting portion 120 by means of gluing or welding, or can be movably connected to the connecting portion 120 by means of a sleeve or tearing, as long as the roller brush 100 is in normal working condition, the connection between the first blocking member 140 and the connecting portion 120 is stable, and at least a part of the first blocking member 140 interferes with the cleaning module 1000.

[0049] In some embodiments, blades are provided on the outer surface of the roller brush body 110 , and the blades extend obliquely along the axial direction on the outer surface of the roller brush body, so that the winding object moves in a direction away from the blocking piece.

[0050] In some embodiments, the roller brush body 110 further includes a bristle mounting portion 113, which is disposed at least on one side of the roller brush body 110 adjacent to the baffle and configured to mount the bristles. The bristle mounting portion 113 is disposed between at least two of the blades and configured to prevent the winding object from moving backward toward the baffle 130. The bristle mounting portion 113 can be disposed on one side of the roller brush body 110 adjacent to the baffle, or on the entire upper surface of the roller brush body 110, wherein the blades are disposed substantially parallel to the bristles.

[0051] In some embodiments, Figure 2 As shown, the bristles have a fixed end connected to the bristle mounting portion 113 and a free end away from the bristle mounting portion 113, and the free end of the bristles is inclined toward the second end 112 of the roller brush body 110. Under this structural design, the hair or dust entangled on the roller brush body 110 will rotate with the roller brush 100, and under the action of the inclined bristles, the entangled materials are transported from the first end 111 of the roller brush body 110 toward the second end 112, so that the entangled materials are transported to the dust collection channel.

[0052] In the second aspect of the embodiment of the present disclosure, a cleaning module 1000 is provided, comprising: a shell 1100, a driving assembly 1400, a second blocking member 1200 and the roller brush 100 mentioned in the first aspect of the embodiment of the present disclosure, wherein the second blocking member 1200 is arranged between the driving assembly 1400 and the roller brush 100, and is configured to prevent entanglements such as hair from entering the interior of the driving assembly 1400.

[0053] In some embodiments, Figure 3 As shown, the cleaning module 1000 includes a housing 1100, and the housing 1100 is provided with a receiving space 1001 for installing the roller brush 100, and an installation space for accommodating the driving assembly 1400 and the second blocking member 1200. The driving assembly 1400 is provided at at least one end of the housing 1100, and is configured to drive the roller brush 100 to rotate.

[0054] Specifically, the driving assembly 1400 is located at a side of the second blocking member 1200 away from the accommodating space 1001, wherein at least a portion of the driving assembly 1400 passes through the second blocking member 1200 and extends toward the accommodating space 1001. The driving assembly 1400 includes a driving shaft 1410 and a driving motor, wherein at least a portion of the driving shaft 1410 passes through the second blocking member 1200 and extends toward the accommodating space 1001, and in response to the roller brush 100 being installed in the accommodating space 1001, the driving shaft 1410 is connected to the roller brush body 110, and the roller brush 100 is adapted to rotate under the drive of the driving motor.

[0055] In some embodiments, there is a gap between the connecting portion 120 and the driving shaft 1410, and at least a portion of the second blocking member 1200 extends into the gap. At this time, the second blocking member 1200 is semi-enclosed and surrounded by the connecting portion 120, which can effectively prevent hair and other entanglements from entering the driving component 1400 when the roller brush 100 is in the working state.

[0056] In some embodiments, a third blocking member 1300 is disposed between the second blocking member 1200 and the driving shaft 1410, and the third blocking member 1300 is movably connected to the driving shaft 1410, and the driving shaft 1410 can rotate axially relative to the third blocking member 1300 to drive the roller brush body 110 to rotate. Specifically, the second blocking member 1200 has an extension portion at one end adjacent to the roller brush 100, and the extension portion is sleeved on the outside of the third blocking member 1300, and a gap is provided between the extension portion of the second blocking member 1200 and the roller brush 100, so that the roller brush 100 can rotate normally. The extension portion is disposed between the connecting portion 120 and the third blocking member 1300, and is configured to prevent the winding object from moving from the connecting portion 120 toward the third blocking member 1300. In some embodiments, the third blocking member 1300 can be an I-shaped ring structure, which is configured to automatically divide the pressure when the roller brush 100 is working, so as to avoid the centrifugal force generated by the drive shaft 1410 during rotation, causing excessive stress between the parts inside the cleaning module 1000, thereby reducing the service life of the parts.

[0057] In some embodiments, the end of the drive shaft 1410 away from the drive motor may be provided with a chamfer, which can make it easier to connect the roller brush body 110 and the drive shaft 1410, and avoid unnecessary mechanical wear when installing or removing the roller brush 100. The setting of the chamfer is conducive to avoiding the extrusion friction between the sharp corner and the brushed steel plate, reducing the compressive stress of the parts, improving the surface quality and preventing the workpiece edge from bursting, improving the toughness of the parts, and increasing the service life of the parts.

[0058] In some embodiments, Figure 3 As shown, the housing 1100 is provided with a receiving space 1001, and the receiving space 1001 is used to receive at least one roller brush 100, and the roller brush 100 is in contact with the operating surface, and the roller brush 100 is driven by the driving assembly 1400 to rotate at high speed to clean the contaminated area of ​​the operating surface.

[0059] The cleaning module 1000 further includes a main brush cover 1500, which is detachably mounted in the accommodation space of the housing 1100 to keep the roller brush 100 in a correct installation position. This ensures that the roller brush 100 does not scratch the cleaning surface when the roller brush 100 rotates at high speed in the housing 1100 to clean the operating surface. In response to the main brush cover 1500 being mounted in the housing 1100, at least one end of the main brush cover 1500 is inserted between the connecting portion 120 and the second blocking member 1200.

[0060] In some embodiments, the main brush cover 1500 includes a stopper 1520. In response to the main brush cover 1500 being installed on the cleaning module 1000, the stopper 1520 contacts at least a portion of the first blocking member 140, that is, at least a portion of the first blocking member 140 interferes with the main brush cover 1500. Since the first blocking member 140 and the stopper 1520 are interference-fitted, the first blocking member 140 can block the gap between the roller brush 100 and the main brush cover 1500, thereby preventing the entangled objects on the roller brush body 110 from entering the interior of the cleaning module and interfering with the normal operation of the roller brush 100.

[0061] In some embodiments, the main brush cover 1500 includes a fourth blocking member 1530 , which is disposed between an end of the connecting portion 120 and the second blocking member 1200 and configured to block the winding object from moving toward the direction where the extending portion is located.

[0062] In some embodiments, the edge portion of the fourth blocking member 1530 and the second blocking member 1200 is provided with a first chamfer, and the edge portion of the second blocking member 1200 in contact with the fourth blocking member 1530 is provided with a second chamfer, and the sizes of the first chamfer and the second chamfer match each other. The chamfer structure design effectively reduces the stress concentration between parts, improves the overall mechanical structure strength of the cleaning module 1000, is more conducive to punching and demolding during the processing process, and has the advantages of safe, beautiful finished products, and long service life.

[0063] In some embodiments, a snap-in groove is provided on the open exterior of the accommodating space 1001, and a first snap-in hook is provided in the snap-in groove; the main brush cover 1500 is provided with a snap-in member 1510. The snap-in member 1510 matches the snap-in groove, and is adapted to move toward the snap-in groove under the action of an external force, and snap-in with the snap-in groove, so as to achieve a stable connection between the housing 1100 and the main brush cover 1500.

[0064] Specifically, the clamping member 1510 includes a buckle, an elastic member, and a second clamping hook. The second clamping hook has an initial position and a pressing position. When the second clamping hook is in the initial position, the second clamping hook is clamped with the first clamping hook. When the second clamping hook is in the pressing position, the second clamping hook is separated from the first clamping hook.

[0065] The buckle hand is connected to the second snap-on hook via the elastic member, and is configured to press the buckle hand under the action of an external force to switch the second snap-on hook from an initial position to a pressing position. When the buckle hand is not subject to an external force, the elastic member is relaxed, and the second snap-on hook is often in the initial position. When the buckle hand is subject to an external force, the elastic member is compressed, and the second snap-on hook switches from the initial position to the pressing position as the external force increases.

[0066] It should be separately explained that the above embodiments are merely exemplary embodiments, and the present disclosure does not limit the shape and structure of the clip 1510. The clip 1510 may also be any other structural component having a second clip hook that can be connected to the first clip hook.

[0067] In some embodiments, after the roller brush 100 is installed in the accommodating space 1001, when the second snap-on hook is in the initial position, there is no extrusion between the main brush cover 1500 and the first blocking member 140. At this time, in the axial direction of the roller brush 100, the projection area of ​​the first blocking member 140 is greater than the projection area of ​​the blocking piece 130.

[0068] When the second snap-on hook is in the pressing position, the main brush cover 1500 squeezes the first blocking member 140 to deform at least a portion of the first blocking member 140 . At this time, in the axial direction of the roller brush 100 , the projected area of ​​the first blocking member 140 is approximately equal to the projected area of ​​the blocking sheet 130 .

[0069] In some embodiments, when the main brush cover 1500 is installed on the housing 1100, the first blocking member 140 interferes with at least a portion of the main brush cover 1500. Figure 4 As shown, at least part of the first blocking member 140 contacts the inner side wall of the main brush cover 1500, and the hardness of the inner side wall of the main brush cover 1500 is much greater than the hardness of the first blocking member 140. Therefore, when the main brush cover 1500 is installed on the housing 1100, the first blocking member 140 is easily deformed locally under the action of the main brush cover 1500. When the roller brush 100 is in a normal working state, the free end of the first blocking member 140 sticks to the inner side wall of the main brush cover 1500. As the roller brush 100 rotates, the free end of the first blocking member 140 is released when passing through one side of the paired operating surface of the main brush cover 1500. Therefore, due to the mutual interference between the first blocking member 140 and the main brush cover 1500, it is possible to block dirt such as hair and prevent dirt from entering the interior of the driving assembly 1400.

[0070] In some embodiments, in response to the main brush cover 1500 being installed on the shell 1100, at least part of the first blocking member 140 interferes with the main brush cover 1500, and the interference amount between the first blocking member 140 and the main brush cover 1500 is 0.2mm~2mm, that is, when the main brush cover 1500 is installed in the accommodating space 1001 and the second snap-on hook is in the pressing position, the main brush cover 1500 causes at least a part of the free end of the first blocking member 140 to deform, and the deformation amount of the free end of the first blocking member 140 is 0.2mm~2mm, thereby blocking the entanglement and preventing dust from entering the interior of the driving assembly 1400.

[0071] In summary, before the cleaning module 1000 starts to work normally, the first blocking member 140 needs to be installed on the connecting portion 120 of the roller brush 100 so that the first blocking member 140 is sleeved outside the connecting portion 120 and abuts against the blocking piece 130 .

[0072] Furthermore, the roller brush 100 assembled with the first blocking member 140 can be installed in the accommodation space 1001 of the cleaning module 1000, so that the roller brush body 110 is connected to the driving shaft 1410 of the driving assembly 1400. Furthermore, the clamping member 1510 of the main brush cover 1500 is docked with the clamping groove on the surface of the housing 1100, so that the clamping member 1510 is switched from the initial state to the installation state to ensure that the main brush cover 1500 is accurately installed in the accommodation space 1001. At this point, the assembly of the cleaning module 1000 is completed, and the driving assembly 1400 can be started to rotate the roller brush 100 to clean the operating surface.

[0073] During the normal operation of the cleaning module 1000, the roller brush body 110 may be wrapped with dirt and dust such as hair on the operating surface. Since the roller brush body 110 is a conical structure, as the roller brush 100 rotates, the dirt and dust wrapped on the surface of the roller brush body 110 will be transported from the first end 111 toward the second end 112, thereby preventing the dirt and dust from entering the driving component of the cleaning module 1000.

[0074] When the roller brush 100 is in a normal working state and rotates at a high speed, if the dirt and dust wrapped on the surface of the roller brush body 110 is close to the first end 111, the setting of the blocking piece 130 can effectively prevent the dirt and dust from entering the driving component of the cleaning module 1000. In order to strengthen the protection of the interior of the cleaning module 1000, a first blocking member 140 is added, at least part of which interferes with the main brush cover 1500, and is configured to prevent the hair wrapped on the roller brush body 110 from entering the cleaning module 1000, so that the cleaning module 1000 can work normally and improve the user experience.
