[0001] This disclosure relates to the technical field of cleaning devices, and more particularly to a rolling brush, a cleaning module and a cleaning device. Technological background

[0002] With the gradual improvement of living standards, people's expectations regarding quality of life are also increasing. More and more people are installing thin floor coverings or tiles in their homes. Floor coverings come in a variety of materials, such as wood or stone, etc. When floors or tiles become stained with dirt and need cleaning, the traditional practice is to use a broom, mop, or dustpan. This method is time-consuming and labor-intensive, and does not encourage people to take an interest in cleaning. This method requires a lot of time and effort and does not motivate people to clean, which is not conducive to maintaining a clean indoor environment. The advent of cleaning appliances has therefore helped, to some extent, to solve the problem of the cumbersome nature of cleaning methods.Since objects wrapped around the roller brush can easily enter the drive assembly during operation of the cleaning device, it is necessary to design a new type of roller brush to protect the drive assembly of said cleaning device.

[0031] It should be understood that, although the terms first, second, third, etc. may be used to describe the embodiments of the present In disclosure, these descriptions should not be limited to these terms. These terms are used solely to distinguish the described objects from one another. For example, without departing from the scope of the embodiments in this disclosure, a first may also be referred to as a second, and similarly, a second may also be referred to as a first. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] It should be understood that the term "and / or", as used here, is simply a description of the association relationship of the associated objects, indicating that three relationships can exist, for example, A and / or B, which can be expressed as: A alone, both A and B, and B alone. Furthermore, the character " / " in this document generally indicates that the associated objects before and after are in an "or" relationship. The singular forms "has", "says", and "the" are also intended to include the majority form, unless the context clearly indicates otherwise.

[0033] In the description of this document, it should be noted that, unless expressly stated or limited, the terms "connected" and "linked" are to be understood in a broad sense, that is, they may be connected in a fixed, removable, or integral manner, mechanically or electrically, directly or indirectly via an intermediate medium. This may be a mechanical or electrical connection; it may be a direct connection or an indirect connection via an intermediate medium. For a person with ordinary skills in the art, the specific meaning of the above terms in this utility model can be understood in particular cases.

[0034] It should also be noted that the terms "including", "comprising", or any other variation thereof are intended to cover non-exclusive inclusion, so that goods or devices comprising a series of elements include not only those elements, but also other elements not expressly listed, or which are inherent in those goods or devices. The same applies to elements not expressly listed or which are inherent in those goods or devices. Without further limitation, the fact that an element is qualified by the phrase "includes a..." does not preclude the existence of another identical element in the products or devices comprising that element.

[0035] In the related technology, due to the existence of a gap (a space) between the connecting part of the roller brush and the housing of said cleaning module, and the gap being relatively large, under normal working conditions, hair and other wrapped objects can extremely easily penetrate the inside of the cleaning module along the gap between the roller brush and the housing, which damages the inside of the cleaning module and affects the normal operation of the brush rolling, or even prevents the cleaning device from being used normally, which impairs the user experience of the device.

[0036] Based on the preceding description, the present invention proposes a roller brush for a cleaning module, comprising: a roller brush body; a connecting part, disposed at one end of said roller brush body, configured to connect the roller brush to a drive assembly of said cleaning module; a stop plate, disposed at one end of said roller brush body, configured to isolate said roller brush body from said connecting part;and a first blocking element, disposed on an outer surface of said connecting part, when said rolling brush is assembled to said drive assembly, wherein at least a portion of said first blocking element interferes with said cleaning module to prevent wrapped objects from entering said drive assembly, wherein, when said rolling brush is not assembled to said drive assembly, the projected area of ​​said first blocking element in an axial direction of said rolling brush is greater than the projected area of ​​said stop plate.

[0037] In the roller brush, cleaning module, and cleaning device according to this disclosure, said roller brush has a stop plate and a first blocking element. Said first blocking element is provided on the outer surface of said connecting part, and at least a portion of said first blocking element interferes with a portion of said cleaning module, which may block a gap between said roller brush and the housing of the cleaning module. When the roller brush is in normal operation, the first blocking element may prevent wrapped objects such as hair from entering the cleaning module along the gap between the roller brush and the housing, thereby preventing internal damage to the cleaning module or affecting the normal operation of the roller brush and enhancing the user experience.

[0038] In this regard, the optional embodiments of this disclosure are described in detail below with the attached figures.

[0039] As illustrated in [Fig. 1], an example embodiment of the present disclosure provides a roller brush 100 for use in a cleaning module 1000 of a cleaning apparatus. Said roller brush 100 comprises a roller brush body 110, a connecting portion 120, a stop plate 130, and a first blocking element 140. The first blocking element 140 is disposed on an outer surface of said connecting portion 120, and at least a portion of said first blocking element 140 is disposed to interfere with at least a portion of said cleaning module 1000, configured to prevent wrapped objects such as hair on said rolling brush body to penetrate into the drive assembly of said cleaning module 1000.

[0040] In certain embodiments, said roller brush body 110 may have a cylindrical or conical structure, as shown in Figures 1 and 2. In some embodiments, said roller brush body 110 may have a conical structure with a first end 111 and a second end 112. In the axial direction of the roller brush 100, the cross-sectional area in the axial direction of the first end 111 is larger than the cross-sectional area in the axial direction of the second end 112. When said roller brush 100 is rotating along its axial direction, wrapped objects such as dirt, dust, hair, and other wrapped objects may become entangled on the surface of the roller brush 100.Since said rolling brush body 110 is of conical structure, when said rolling brush 100 rotates, objects wrapped on the surface of the rolling brush body 110 will be transported from said first end 111 towards said second end 112, preventing dirt and dust from entering the drive assembly of said cleaning module 1000.

[0041] In certain embodiments, in order to prevent objects wrapped on the surface of the roller brush 100 from entering the drive assembly of the cleaning module 1000, said roller brush 100 further comprises a connecting portion 120 and a stop plate 130. Said connecting portion 120 is provided at a first end 111 of said roller brush body 110 and extends axially towards said roller brush 100, configured to connect the connection of said roller brush 100 with said cleaning module 1000. Said stop plate 130 is provided at said first end 111 and extends annularly in a radial direction towards said roller brush 100.In the radial direction of said rolling brush 100, the diameter where said stop plate 130 is located is greater than the diameter of said first end 111, configured to isolate said rolling brush body 110 from said connecting part 120, to prevent objects wrapped around said rolling brush body 110 from entering said drive assembly.

[0042] More specifically, when said rolling brush 100 rotates at a high speed in a normal operating condition, the dirt tangled on the surface of said rolling brush body 110 will be transported from said first end 111 towards said second end 112, and the placement of said stop plate 130 can effectively prevent the dirt from entering the drive assembly of said cleaning module 1000.

[0043] In certain embodiments, objects wrapped on the surface of the roller brush body 110 can move around said stop plate 130 in the direction where said connecting part 120 is located, which means that a first locking element 140 is provided on the outer surface of said connecting part 120. Said first locking element 140 is an annular structural element, the inner diameter of said first locking element 140 being slightly larger than the outer diameter of said connecting part 120, to be fitted onto the outer lateral wall of the connecting part 120 to connect to said roller brush body 110. Due to the mounting of said roller brush 100 on said cleaning module 1000, at least a part of said first locking element 140 interferes with said cleaning module 1000, to prevent objects wrapped on said roller brush body 110 from entering the drive assembly of said cleaning module 1000.

[0044] More specifically, said rolling brush 100 is in its natural state before said rolling brush 100 is mounted on said cleaning module 1000. Once said first blocking element 140 is mounted on said connecting part 120, in the axial direction of said rolling brush 100, the projected surface of said first blocking element 140 is significantly larger than the projected surface of said stop plate 130.

[0045] Once said first locking element 140 is mounted on said connecting part 120, said roller brush 100 can be mounted on said cleaning device, said roller brush 100 then being in a mounted state. In this state, the projected surface area of ​​said first locking element 140 is approximately equal to the projected surface area of ​​said stop plate 130 in the axial direction of said roller brush 100, due to the fact that at least a part of said first locking element 140 is in contact with and interferes with a part of said cleaning module 1000.When said roller brush 100 is in the installed state, because at least a part of said first blocking element 140 interferes with a part of said cleaning module 1000, hair and dirt tangled on said roller brush body 110 do not enter the cleaning device along the gap between the connecting part 120 and the housing 1100 during the operation of said roller brush 100, which ensures the safe use of the roller brush 100 during the working process.

[0046] In certain embodiments, in the axial direction of said roller brush body 110, said connecting part 120 has a width H1 and said first blocking element 140 has a width H2, and H1 > H2. That is to say, the width of said first blocking element 140 is not greater than the width of said connecting part 120. On the one hand, it is possible to prevent the installation of the roller brush 100 or the installation of other structural parts inside the cleaning module 1000 from being affected due to the excessive width of said first blocking element 140, and on the other hand, the housing prevents a portion of the first blocking element 140 it itself can be wound inside the cleaning module 1000 along the spaces between the parts and cause malfunction of the rolling brush 100.

[0047] In certain embodiments, said first blocking element 140 may be a flexible structural element such as an implanted bristle or a bristle strip, so that the normal rotation of the rolling brush 100 will not be affected in the operating state due to higher friction or a higher stopping force generated by the first blocking element 140 and the cleaning module 1000. When said bristle strip or implanted bristle is mounted on said connecting part 120, said bristle strip or implanted bristle is substantially perpendicular to the outer surface of said connecting part 120, so that said bristle strip or implanted bristle can interfere to the maximum to block wrapped objects such as hair and dirt by preventing them from entering the cleaning module 1000.At least a part of said first blocking element 140 is in contact with said stop plate 130, and in the axial direction of said rolling brush body 110, said stop plate 130 has a limiting effect on said first blocking element 140.

[0048] It should be noted that this disclosure does not specifically limit the method of connection between said first blocking element 140 and said connecting part 120. Said first blocking element 140 may be fixedly mounted on said connecting part 120, for example by gluing or welding, etc., or movably connected to said connecting part 120 by sleeving or tear-off connection, etc., provided that it is ensured that said rolling brush 100 is in a normal operating condition, that the connection between said first blocking element 140 and said connecting part 120 is stable, and that at least a portion of said first blocking element 140 interferes with the cleaning module 1000.

[0049] In certain embodiments, said rolling brush body 110 is provided with blades on the outer surface of said rolling brush body 110, said blades extending inclinedly in an axial direction on the outer surface of said rolling brush body to move said wrapped objects in a direction opposite to said stop plate.

[0050] In certain embodiments, said roller brush body 110 further comprises a bristle mounting portion 113, said bristle mounting portion 113 being disposed on at least one side of said roller brush body 110 adjacent to said stop plate, configured to mount said bristles. Said bristle mounting portion 113 is disposed between at least two of said blades, and is configured to prevent said wrapped objects from moving in the opposite direction towards said stop plate 130. Said bristle mounting portion 113 may be provided on one side of said roller brush body 110 adjacent to said stop plate, or on the entire upper surface of said roller brush body 110, in which said blades are provided substantially parallel to said bristles.

[0051] In some embodiments, as illustrated in [Fig.2], the bristles have a fixed end connected to the bristle mounting part 113 and a free end away from the bristle mounting part 113, and the free end of the bristles is inclined towards the second end 112 of the roller brush body 110, and in this structural design, hair or dirt and dust tangled on the roller brush body 110 will rotate with the roller brush 100, and the wrapped objects will be transported by the inclined bristles from the first end 111 of the roller brush body 110 to the second end 112, so that the wrapped objects are transported towards the dust collection channel.

[0052] In a second aspect of an example embodiment of this disclosure, a cleaning module 1000 is proposed comprising: a housing 1100, a drive assembly 1400, a second blocking element 1200, and a rolling brush 100 mentioned in the first aspect of an example embodiment of this disclosure, said second blocking element 1200 being disposed between said drive assembly 1400 and said rolling brush 100, which is configured to prevent wrapped objects such as hair from entering the drive assembly 1400.

[0053] In certain embodiments, as illustrated in [Fig.3], said cleaning module 1000 comprises a housing 1100, said housing 1100 being provided with a housing space 1001 for mounting said roller brush 100, and a mounting space for housing said drive assembly 1400 and the second locking element 1200. Said drive assembly 1400 is provided at at least one end of said housing 1100, configured to drive said roller brush 100 to rotate.

[0054] More specifically, said drive assembly 1400 is disposed on one side of said second blocking element 1200 away from said housing space 1001. At least a portion of said drive assembly 1400 extends through said second blocking element 1200 in the direction of said housing space 1001. Said drive assembly 1400 comprises a drive shaft 1410 and a drive motor, at least a portion of the drive shaft 1410 extends through said second blocking element 1200 extending in the direction of housing space 1001, in response to said roller brush 100 mounted in said housing space 1001, said drive shaft 1410 being coupled to said roller brush body 110, said roller brush 100 being adapted to be driven in rotation by said drive motor.

[0055] In certain embodiments, there is a gap between said connecting part 120 and said drive shaft 1410, and at least a portion of said second locking element 1200 extends into said gap. Thus, said second locking element 1200 encloses a portion of said connecting part 120, which can effectively prevent wrapped objects such as hair and other tangled materials from entering the drive assembly 1400 when the roller brush 100 is in operation.

[0056] In certain embodiments, a third locking element 1300 is provided between said second locking element 1200 and said drive shaft 1410. Said third locking element 1300 is movably connected to said drive shaft 1410, and said drive shaft 1410 can rotate relative to said third locking element 1300 in an axial direction in order to rotate said roller brush body 110. More specifically, said second locking element 1200 has an extension at one end adjacent to said roller brush 100, said extension being fitted onto the outer side of said third locking element 1300, and a space is provided between said extension of said second locking element 1200 and said roller brush 100 to allow said roller brush 100 to rotate normally.The extension is provided between the connecting part 120 and the third locking element 1300, configured to prevent the wrapped objects from moving from the connecting part 120 to the third locking element 1300. In some embodiments, the third locking element 1300 may be a structural element in the form of an I-ring configured to automatically divide the pressure during the operation of the rolling brush 100, avoiding a high centrifugal force generated by the drive shaft 1410 during rotation, which can cause excessive stress between the elements inside the cleaning module 1000, thus leading to a decrease in the service life of the parts.

[0057] In certain embodiments, one end of said drive shaft 1410 away from said drive motor may be provided with a chamfer, capable of facilitating the connection of said roller brush body 110 with said drive shaft 1410 during connection, and of preventing undue mechanical abrasion during the mounting or dismounting of the roller brush 100. The chamfer makes it possible to avoid extrusion friction between the sharp corners and the steel plate of the rubber, to reduce the compressive stress of the parts, to improve the surface quality and prevent the edge of the workpiece from chipping, to improve the toughness of the parts and to improve the service life of the parts.

[0058] In certain embodiments, as illustrated in [Fig. 3], said housing 1100 is provided with a housing space 1001, said housing space 1001 being used for to house at least one rolling brush 100, said rolling brush 100 being in contact with an operating surface, said rolling brush 100 being driven at high speed to clean the contaminated area of ​​the operating surface by means of a drive assembly 1400.

[0059] Said cleaning module 1000 further includes a main brush cover 1500, said main brush cover 1500 being removably assembled in the housing space of said housing 1100 to hold said roller brush 100 in the correct mounting position. This ensures that said roller brush 100 rotates at high speed inside the housing 1100 to clean the operating surface without the main brush cover 1500 scratching the cleaning surface. In response to the assembly of said main brush cover 1500 onto said housing 1100, at least one end of said main brush cover 1500 is inserted between said connecting part 120 and said second locking element 1200.

[0060] In certain embodiments, said main brush cover 1500 includes a stop portion 1520. Due to the mounting of said main brush cover 1500 on said cleaning module 1000, said stop portion 1520 is in contact with at least a part of said first blocking element 140, i.e., at least a part of said first blocking element 140 interferes with said main brush cover 1500. As said first blocking element 140 is fitted (interference fit) with said stop portion 1520, said first blocking element 140 can block the space between said roller brush 100 and said main brush cover 1500, preventing objects wrapped around said roller brush body 110 from entering said cleaning module and disrupting the normal operation of said roller brush 100.

[0061] In certain embodiments, said main brush cover 1500 includes a fourth blocking element 1530, said fourth blocking element 1530 being provided between the end of said connecting part 120 and said second blocking element 1200, configured to prevent said wrapped objects from moving in the direction in which said extension is located.

[0062] In certain embodiments, a first chamfer is provided at the edge portion of said fourth locking element 1530 and said second locking element 1200, and a second chamfer is provided at the edge portion of said second locking element 1200 in contact with said fourth locking element 1530, and the sizes of said first chamfer and said second chamfer correspond, and the structural design of the chamfer effectively reduces the concentration of stresses between the parts and improves the overall mechanical structural strength of the cleaning module assembly 1000, which is more suitable for stamping and during demolding, and offers the advantages of safe and beautiful finished products and a long service life.

[0063] In certain embodiments, said housing space 1001 is provided with a hooking slot on the outside of the open mouth of said housing space 1001, and said hooking slot is provided with a first hooking hook; said main brush cover 1500 is provided with a snap-on element 1510. Said snap-on element 1510 corresponds to said hooking slot and is capable of being moved in the direction of said hooking slot under the action of an external force and of being engaged with said hooking slot, thus achieving a stable connection between said housing 1100 and said main brush cover 1500.

[0064] More specifically, said latching element 1510 comprises a fastener, an elastic element, and a second latching hook. Said second latching hook has an initial position and a compressed position; said second latching hook is engaged with said first latching hook when said second latching hook is in the initial position, and said second latching hook is separated from said first latching hook when said second latching hook is in the compressed position.

[0065] Said closure and said second hook are connected by said elastic element, configured to press the closure under the effect of an external force in order to move said second hook from an initial position to a compressed position; when said closure is not subjected to an external force, said elastic element is relaxed and said second hook is still in the initial position; when said closure is subjected to an external force, said elastic element is compressed and said second hook moves from the initial position to the compressed position with an increase in the external force.

[0066] It should be noted separately that the above embodiments are only non-limiting examples and that this disclosure does not limit the form and structure of said snap-on element 1510. Said snap-on element 1510 may be any other structural component having a second snap hook that can be connected to the first snap hook.

[0067] In certain embodiments, after said rolling brush 100 is mounted in said housing space 1001, and the second hook is in initial position, there is no compression between said main brush cover 1500 and said first blocking element 140, at that time, in the axial direction of said rolling brush 100, the projected surface of said first blocking element 140 is greater than the projected surface of said stop plate 130.

[0068] When said second hook is in the compressed position, said main brush cover 1500 compresses said first locking element 140, deforming at least a part of said first blocking element 140, at which point, in the axial direction of said rolling brush 100, the projected surface of said first blocking element 140 is approximately equal to the projected surface of said stop plate 130.

[0069] In certain embodiments, when said main brush cover 1500 is mounted in said housing 1100, said first blocking element 140 interferes with at least a portion of said main brush cover 1500, as illustrated in [Fig. 4]. Indeed, at least a portion of said first blocking element 140 is in contact with the inner wall of said main brush cover 1500, and the hardness of the inner wall of said main brush cover 1500 is significantly greater than the hardness of said first blocking element 140, with the result that when said main brush cover 1500 is mounted on said housing 1100, said first blocking element 140 is susceptible to local deformation under the action of said main brush cover 1500.When said roller brush 100 is in a normal operating state, the free end of said first blocking element 140 comes to rest against the inner side wall of said main brush cover 1500, and when said roller brush 100 rotates, the free end of said first blocking element 140 is released by passing through one of the two operating faces of said main brush cover 1500. Thus, due to the mutual interference of said first blocking element 140 and said main brush cover 1500, it is possible to block dirt such as hair and prevent dirt from entering said drive assembly 1400.

[0070] In certain embodiments, due to the mounting of said main brush cover 1500 on said housing 1100, at least a part of said first locking element 140 interferes with said main brush cover 1500, and the amount of interference between said first locking element 140 and said main brush cover 1500 is 0.2mm~2mm, i.e. that in the case where said main brush cover 1500 is mounted on said housing space 1001 and said second latch hook is in the compressed position, said main brush cover 1500 deforms at least a part of said free end of said first locking element 140, and the amount of deformation of said free end is 0.2mm~2mm, in order to achieve the blocking of wound objects and to prevent dirt and dust from entering the drive assembly 1400.

[0071] In summary, before the normal operation of said cleaning module 1000 begins, it is first necessary to install said first blocking element 140 on the connection part 120 of said rolling brush 100, so that said first locking element 140 is fitted onto the outside of said connection part 120 and comes to rest against said stop plate 130.

[0072] Furthermore, the roller brush 100 assembled with said first locking element 140 can be installed in the housing space 1001 of said cleaning module 1000, such that said roller brush body 110 is connected to the drive shaft 1410 of the drive assembly 1400. In addition, the snap-on element 1510 of said main brush cover 1500 with the snap-on groove on the surface of said housing 1100 moves said snap-on element 1510 from an initial state to a mounted state to ensure that said main brush cover 1500 is precisely mounted in said housing space 1001. At that point, the assembly of said cleaning module 1000 is complete, and the drive assembly 1400 can be activated to rotate the roller brush 100.

[0073] During the normal operation of said cleaning module 1000, said rolling brush body 110 may be coated with dirt and dust such as hair on the operating surface, and as said rolling brush body 110 is of conical structure, when said rolling brush 100 is rotating, the dirt and dust coating the surface of the rolling brush body 110 will be transported towards said second end 112 from said first end 111, so as to prevent the dirt and dust from entering the drive assembly of said cleaning module 1000.

[0074] When said roller brush 100 is rotating at high speed in a normal operating state, if tangled dirt on the surface of said roller brush body 110 is near said first end 111, the arrangement of said blocking plate 130 is provided to effectively prevent dirt from entering the drive assembly of said cleaning module 1000. In order to reinforce the protection of the interior of said cleaning module 1000, a first blocking element 140 is added, and at least a portion of said first blocking element 140 interferes with said main brush cover 1500, configured to prevent tangled hair and fur on said roller brush body 110 from entering the cleaning module 1000, so as to allow the cleaning module 1000 to operate normally and to improve the user experience.

[0075] The embodiment examples of this disclosure further provide a cleaning device comprising said cleaning module as provided in any embodiment of this disclosure as above.
