Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of cleaning devices, in particular to a roller brush, a cleaning module and a cleaning device. STATE OF THE ART

[0002] With the gradual improvement of living standards, people's demands for quality of life are also rising. More and more people are installing high-quality flooring or tiles on their homes. A variety of flooring materials are available, such as wood or stone flooring. When floors or tiles are dirty and need cleaning, traditional practices involve using a broom, mop, or dustpan. However, this is time-consuming and labor-intensive, does not contribute to increasing people's interest in cleaning, and is also not practical for maintaining indoor cleanliness. Against this background, the advent of cleaning appliances has solved this problem of cumbersome cleaning methods to a certain extent.However, the problem with cleaning equipment is that tangles on a roller brush can easily penetrate the interior of a drive assembly. Therefore, it is necessary to develop a new type of roller brush to protect the drive assembly of the cleaning equipment. REVELATION OF REVELATION

CONCRETE EMBODIMENTS

[0023] To better understand the object, technical solutions, and advantages of the present disclosure, the present disclosure will be explained in more detail below with reference to the accompanying drawings. It should be understood that the described embodiments represent only some of the present disclosure, rather than all of the embodiments. All other embodiments that can be obtained by those of ordinary skill in the art from the embodiments of the disclosure without inventive steps are also within the scope of the disclosure.

[0024] The terms used in the embodiments of the present disclosure are for the purpose of describing particular embodiments only, without being intended to limit the present disclosure.

The term "multiple" typically indicates a number of at least two, and other quantities are similarly understood.

[0025] It should be understood that although the terms "first," "second," "third," etc., are used in the embodiments of the present disclosure for descriptive purposes, this description should not be limited to such terms. Such terms are used only to distinguish described items from one another. For example, without departing from the scope of the embodiments of the present disclosure, a "first" item may also be referred to as a "second" item. Similarly, a "second" item may also be referred to as a "first" item. Furthermore, it should be understood that the terms "first," "second," "third," etc., are not intended to imply or explicitly indicate relative importance. Rather, they are used for descriptive purposes only.

[0026] It should also be understood that the term "and / or" as used herein merely describes the relationship between the objects involved, meaning that three relationships are possible. For example, with "A and / or B," three cases are possible: the sole presence of A, the sole presence of B, and the simultaneous presence of A and B. Furthermore, the symbol " / " usually indicates the relationship "or" between related objects that come before or after it.

One of ordinary skill in the art can use the facts of the case to determine the intended meaning of the terms mentioned in accordance with the present utility model.

[0028] It should also be noted that the terms "comprise," "include," or any variations thereof, are intended to be non-exclusive, so that goods or equipment comprising a set of elements may include, in addition to such elements, other elements not explicitly listed or elements that the goods or equipment include as standard. Without further limitation, where an element is specified by the phrase "comprises a...", it is understood that other identical elements may also be present in the goods or equipment comprising that element.

[0029] In related art, due to the presence and large size of a gap between a connecting portion of a roller brush and a housing of a cleaning module, during normal operation, entanglements such as hair easily penetrate into the interior of the cleaning module along the gap between the roller brush and the housing. This may cause damage to the cleaning module, affect the normal operation of the roller brush, and even cause the cleaning device to malfunction, thereby affecting the user experience.

[0030] Based on the above description, the present invention provides a roller brush for a cleaning module.It comprises: a brush body; a connecting portion arranged at one end of the brush body and configured to connect the roller brush to a drive assembly of the cleaning module; a deflector plate arranged at one end of the brush body and configured to separate the brush body from the connecting portion; a first locking element arranged on the outer surface of the connecting portion, wherein, when the roller brush is mounted on the drive assembly, at least a part of the first locking element and the cleaning module interfere with each other to prevent entanglements from entering the drive assembly, wherein, when the roller brush is not mounted on the drive assembly, the projection area of the first locking element in the axial direction of the roller brush is larger than the projection area of the deflector plate.

[0031] In the roller brush, the cleaning module, and the cleaning device according to the present disclosure, the roller brush includes a deflector plate and a first blocking member. The first blocking member is disposed on the outer surface of the connecting portion, and at least a part of the first blocking member and a part of the cleaning module interfere with each other, thereby blocking a gap between the roller brush and the housing of the cleaning module. When the roller brush is in the normal operating state, the provision of the first blocking member can prevent entanglements such as hair along the gap between the roller brush and the housing from entering the interior of the cleaning module, thereby causing damage to the cleaning module or interfering with the normal operation of the roller brush, thus contributing to an improved user experience.

[0032] Against this background, optional embodiments of the present disclosure are described in more detail below with reference to the accompanying drawings.

[0033] As in Fig. 1, one embodiment of the present disclosure provides a roller brush 100 for a cleaning module 1000 of a cleaning device. The roller brush 100 includes a brush body 110, a connecting portion 120, a deflector plate 130, and a first locking element 140. The first locking element 140 is disposed on the outer surface of the connecting portion 120, and at least a portion of the first locking element 140 and at least a portion of the cleaning module 1000 interfere with each other to prevent entanglements, such as hair, on the brush body from penetrating a drive assembly of the cleaning module 1000.

[0034] In some embodiments, the brush body 110 may be formed as a cylindrical or conical structure. As shown in the Fig. 1 and Fig. 2, the brush body 110 may be formed as a conical structure and have 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 larger than that of the second end 112. When the roller brush 100 rotates along the axial direction of the roller brush 100, entanglements such as dirt or hair may become trapped on the surface of the roller brush 100. Since the brush body 110 is formed as a conical structure, the entanglements trapped on the surface of the brush body 110 are conveyed from the first end 111 toward the second end 112 with the rotation of the roller brush 100. This prevents dirt from entering the interior of the drive assembly of the cleaning module 1000.

[0035] In some embodiments, the roller brush 100 additionally includes the connecting portion 120 and the deflector plate 130 to prevent entanglements on the surface of the roller brush 100 from entering the drive assembly of the cleaning module 1000. The connecting portion 120 is arranged at the first end 111 of the brush body 110 and extends in the axial direction of the roller brush 100. It serves to connect the roller brush 100 to the cleaning module 1000. The deflector plate 130 is arranged at the first end 111 and extends annularly in the radial direction of the roller brush 100. The diameter of the deflector plate 130 in the radial direction of the roller brush 100 is larger than the diameter of the first end 111. The deflector plate is configured to separate the brush body 110 from the connecting portion 120 in order to prevent entanglements on the brush body 110 from entering the interior of the drive assembly.

[0036] Specifically, when the roller brush 100 rotates at high speed in normal operation, the dirt adhering to the surface of the brush body 110 is conveyed from the first end 111 toward the second end 112. The arrangement of the deflector plate 130 can effectively prevent dirt from entering the interior of the drive assembly of the cleaning module 1000.

[0037] In some embodiments, tangles on the surface of the brush body 110 can bypass the deflector plate 130 and move toward the connecting portion 120. Therefore, the first locking element 140 is provided on the outer surface of the connecting portion 120. The first locking element 140 is an annular member, and its inner diameter is slightly larger than the outer diameter of the connecting portion 120. It is configured to be slid onto the outer side wall of the connecting portion 120 to connect to the brush body 110. In response to the assembly of the roller brush 100 to the cleaning module 1000, at least a portion of the first locking element 140 and the cleaning module 1000 interfere with each other to prevent tangles on the brush body 110 from entering the drive assembly of the cleaning module 1000.

[0038] In detail, the roller brush 100 is in a natural state before the roller brush 100 is mounted on the cleaning module 1000. When the first locking element 140 is mounted on the connecting portion 120, the projection area of the first locking element 140 in the axial direction of the roller brush 100 is significantly larger than the projection area of the deflector plate 130.

[0039] After the first locking element 140 has been mounted on the connecting section 120, the roller brush 100 can be mounted on the cleaning device. The roller brush 100 is now in the mounted state. In this state, at least a portion of the first locking element 140 and a portion of the cleaning module 1000 touch each other and interfere with each other. In the axial direction of the roller brush 100, the projection areas of the first locking element 140 and the deflector plate 130 are approximately equal. When the roller brush 100 is in the mounted state, the mutual interference of at least a portion of the first locking element 140 and a portion of the cleaning module 1000 prevents hair and dirt caught on the brush body 110 from penetrating into the interior of the cleaning device along the gap between the connecting section 120 and the housing 1100 during operation of the roller brush 100.This ensures the safety of use of the roller brush 100 during operation.

[0040] In some embodiments, the width of the connecting portion 120 in the axial direction of the brush body 110 is H1, and the width of the first locking element 140 is H2, where H1 ≥ H2. This means that the width of the first locking element 140 is not greater than the width of the connecting portion 120. On the one hand, this prevents an excessively large width of the first locking element 140 from impairing the assembly of the roller brush 100 or the assembly of other components in the cleaning module 1000. On the other hand, it prevents a part of the first locking element 140 itself from entering the interior of the cleaning module 1000 along a gap between the components and impairing the smooth operation of the roller brush 100.

[0041] In some embodiments, the first blocking element 140 may consist of a soft component, such as planted bristles or a bristle strip. This prevents excessive friction or contact force between the first blocking element 140 and the cleaning module 1000 from impairing the normal rotational movement of the roller brush 100 during operation. When the planted bristles or the bristle strip are mounted on the connecting portion 120, the planted bristles or the bristle strip are substantially perpendicular to the outer surface of the connecting portion 120. This allows the planted bristles or the bristle strip to exert their maximum disruptive effect and effectively prevent entanglements such as hair or dirt from entering the interior of the cleaning module 1000. At least a portion of the first blocking element 140 is in contact with the deflector plate 130.In the axial direction of the brush body 110, the deflector plate 130 exerts a limiting effect on the first blocking element 140.

[0042] It should be noted that the present disclosure does not impose any specific limitations on the type of connection between the first locking element 140 and the connecting portion 120. The first locking element 140 can be fixedly mounted to the connecting portion 120, for example, by gluing, welding, or similar methods. Alternatively, it can also be movably connected to the connecting portion 120 by sliding, hook-and-loop connection, or the like, provided that a stable connection between the first locking element 140 and the connecting portion 120 is ensured during normal operation of the roller brush 100 and at least a portion of the first locking element 140 and the cleaning module 1000 do not interfere with each other.

[0043] In some embodiments, blades are provided on the outer surface of the brush body 110, which blades extend obliquely along the outer surface of the brush body in the axial direction in order to move the entanglements in the direction away from the deflector plate.

[0044] In some embodiments, the roller brush 110 further includes a brush bristle mounting portion 113 disposed at least on the side of the brush body 110 near the deflector plate and configured to mount the brush bristles. The brush bristle mounting portion 113 is disposed between at least two of the blades to prevent the tangles from moving backward toward the deflector plate 130. The brush bristle mounting portion 113 can be disposed on the side of the brush body 110 near the deflector plate or on the entire upper surface of the brush body 110. The blades and the brush bristles are arranged approximately parallel to each other.

[0045] In some embodiments, as in Fig. 2, the individual bristle has a fixed end connected to the brush bristle mounting portion 113 and a free end remote from the brush bristle mounting portion 113. The free end of the individual bristle is inclined toward the second end 112 of the brush body 110. As a result, hair or dirt caught on the brush body 110 is conveyed from the first end 111 of the brush body 110 toward the second end 112 with the rotation of the roller brush 100 under the action of the inclined bristles, so that the tangles are directed into a dust collection channel.

[0046] According to a second aspect of the embodiments of the present disclosure, a cleaning module 1000 is provided, which includes a housing 1100, a drive assembly 1400, a second locking element 1200, and the roller brush 100 described in the first aspect of the present disclosure. The second locking element 1200 is disposed between the drive assembly 1400 and the roller brush 100 and is configured to prevent entanglements such as hair from penetrating the interior of the drive assembly 1400.

[0047] In some embodiments, as in Fig. As shown in Figure 3, the cleaning module 1000 comprises the housing 1100, which is provided with a receiving space 1001 for mounting the roller brush 100 and a mounting space for receiving the drive assembly 1400 and the second locking element 1200. The drive assembly 1400 is arranged at at least one end of the housing 1100 and is configured to drive the roller brush 100 to rotate.

[0048] Specifically, the drive assembly 1400 is located on a side of the second locking element 1200 remote from the receiving space 1001. At least a portion of the drive assembly 1400 extends through the second locking element 1200 toward the receiving space 1001. The drive assembly 1400 includes a drive shaft 1410 and a drive motor. At least a portion of the drive shaft 1410 extends through the second locking element 1200 toward the receiving space 1001. In response to the mounting of the roller brush 100 in the receiving space 1001, the drive shaft 1410 is connected to the brush body 110, such that the roller brush 100 is configured to rotate under the drive of the drive motor.

[0049] In some embodiments, a gap exists between the connecting portion 120 and the drive shaft 1410, into which at least a portion of the second locking element 1200 extends. In this case, the second locking element 1200 surrounds the connecting portion 120 in a semi-closed manner, which can effectively prevent entanglements such as hair from entering the interior of the drive assembly 1400 during operation of the roller brush 100.

[0050] In some embodiments, a third locking element 1300 is provided between the second locking element 1200 and the drive shaft 1410. The third locking element 1300 is movably connected to the drive shaft 1410 such that the drive shaft 1410 can rotate relative to the third locking element 1300 in the axial direction to rotate the brush body 110. In particular, the second locking element 1200 has an extension portion at one end near the roller brush 100, which is slid externally onto the third locking element 1300. A gap is provided between the extension portion of the second locking element 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 locking element 1300 and is configured to prevent the tangles from moving from the connecting portion 120 toward the third locking element 1300. In some embodiments, the third locking element 1300 may be an H-shaped annular member configured to automatically distribute pressure during operation of the roller brush 100. This prevents excessive centrifugal force generated by the rotation of the drive shaft 1410 from causing excessive tension between the parts in the cleaning module 1000, which shortens the service life of the parts.

[0051] In some embodiments, an end of the drive shaft 1410 remote from the drive motor may be provided with a chamfer. This facilitates the connection of the brush body 110 to the drive shaft 1410 and avoids unnecessary mechanical wear during assembly or disassembly of the roller brush 100. The arrangement of the chamfer helps to avoid pressure and friction between sharp edges and a coated steel plate, reduces stress concentration on the parts, improves surface quality, and prevents cracking of a cutting edge of a workpiece. This increases the toughness of the parts and extends their service life.

[0052] In some embodiments, as in Fig. 3, the housing 1100 is provided with the receiving space 1001, which serves to receive at least one roller brush 100. The roller brush 100 is in contact with a work surface and is set into rapid rotation by the drive arrangement 1400 in order to clean dirty areas of the work surface.

[0053] The cleaning module 1000 further includes a main brush cover 1500 removably mounted in the receiving space of the housing 1100 to hold the roller brush 100 in the correct mounting position. This ensures that the roller brush 100 rotates at high speed in the housing 1100 to clean the work surface without the main brush cover 1500 scratching the surface to be cleaned. In response to the mounting of the main brush cover 1500 to the housing 1100, at least one end of the main brush cover 1500 is inserted between the connecting portion 120 and the second locking member 1200.

[0054] In some embodiments, the main brush cover 1500 includes an abutment portion 1520. In response to assembly of the main brush cover 1500 to the cleaning module 1000, the abutment portion 1520 contacts at least a portion of the first locking member 140, that is, at least a portion of the first locking member 140 and the main brush cover 1500 interfere with each other. Due to the interference fit of the first locking member 140 and the abutment portion 1520, the first locking member 140 can block the gap between the roller brush 100 and the main brush cover 1500. This prevents tangles on the brush body 110 from entering the interior of the cleaning module and interfering with the normal operation of the roller brush 100.

[0055] In some embodiments, the main brush cover 1500 includes a fourth locking member 1530 disposed between an end portion of the connecting portion 120 and the second locking member 1200 for preventing tangles from moving toward the extension portion.

[0056] In some embodiments, a first chamfer is provided at the edge region of the fourth locking element 1530 and the second locking element 1200, while a second chamfer is provided at an edge region of the second locking element 1200 in contact with the fourth locking element 1530. The first and second chamfers are matched in size. This chamfer structure effectively reduces stress concentration between the parts, increases the overall mechanical strength of the cleaning module 1000, and facilitates punching and demolding during the machining process, thus advantageously achieving a safe, aesthetically pleasing end product with a long service life.

[0057] In some embodiments, a locking groove, in which a first locking hook is provided, is provided outside an opening of the receiving space 1001. The main brush cover 1500 is equipped with a locking element 1510. The locking element 1510 is matched to the locking groove and is suitable for being moved in the direction of the locking groove under the action of an external force and for being in locking connection with the locking groove, thereby establishing a stable connection between the housing 1100 and the main brush cover 1500.

[0058] Specifically, the locking element 1510 comprises a handle, an elastic element, and a second locking hook. The second locking hook has a home position and a push position. When the second locking hook is in the home position, it is in locking connection with the first locking hook. When the second locking hook is in the push position, it detaches from the first locking hook.

[0059] The handle is connected to the second locking hook via the elastic element and is configured to be pressed under external force to move the second locking hook from the home position to the push position. When no external force acts on the handle, the elastic element relaxes and the second locking hook remains in the home position. When an external force acts on the handle, the elastic element is compressed, and the second locking hook moves from the home position to the push position as the external force increases.

[0060] It should be noted that the above-mentioned embodiments are merely exemplary. The present disclosure does not limit the shape and structure of the locking element 1510. The locking element 1510 may also be any other component that has the second locking hook and can be connected to the first locking hook.

[0061] In some embodiments, the main brush cover 1500 and the first locking element 140 are not pressed against each other when the roller brush 100 is mounted in the receiving space 1001 and the second locking hook is in the home position. In this case, the projection area of the first locking element 140 in the axial direction of the roller brush 100 is larger than the projection area of the deflector plate 130.

[0062] When the second locking hook is in the pressing position, the main brush cover 1500 compresses the first locking element 140, thereby deforming at least a portion of the first locking element 140. In this case, the projection area of the first locking element 140 in the axial direction of the roller brush 100 is approximately equal to the projection area of the deflector plate 130.

[0063] In some embodiments, when the main brush cover 1500 is mounted in the housing 1100, the first locking member 140 and at least a portion of the main brush cover 1500 interfere with each other when the main brush cover 1500 is mounted to the housing 1100. As shown in Fig.4, at least a portion of the first locking element 140 is in contact with the inner side wall of the main brush cover 1500. The hardness of the inner side wall of the main brush cover 1500 is significantly higher than that of the first locking element 140. Therefore, after the main brush cover 1500 is mounted to the housing 1100, the first locking element 140 is susceptible to local deformation under the action of the main brush cover 1500. When the roller brush 100 is in the normal operating state, a free end of the first locking element 140 rests against the inner side wall of the main brush cover 1500. With the rotation of the roller brush 100, the free end of the first locking element 140 is released upon passing a side of the main brush cover 1500 opposite the work surface.Due to the mutual interference of the first locking element 140 and the main brush cover 1500, a shield against hair and other dirt can be achieved and thus dirt can be prevented from entering the interior of the drive assembly 1400.

[0064] In some embodiments, at least a portion of the first locking member 140 and the main brush cover 1500 interfere with each other in response to the assembly of the main brush cover 1500 to the housing 1100. The interference amount of the first locking member 140 and the main brush cover 1500 is 0.2 mm to 2 mm. That is, when the main brush cover 1500 is mounted in the receiving space 1001 and the second latch is in the pressing position, at least a portion of the free end of the first locking member 140 is deformed by the main brush cover 1500. The amount of deformation of the free end of the first locking member 140 is 0.2 mm to 2 mm, thereby blocking entanglement and preventing debris from entering the interior of the drive assembly 1400.

[0065] In summary, before normal operation of the cleaning module 1000, it is first necessary to mount the first locking element 140 on the connecting portion 120 of the roller brush 100, so that the first locking element 140 is pushed onto the outside of the connecting portion 120 and rests against the deflector plate 130.

[0066] Furthermore, the roller brush 100, to which the first locking element 140 is mounted, can be mounted in the receiving space 1001 of the cleaning module 1000, so that the brush body 110 is connected to the drive shaft 1410 of the drive assembly 1400. Furthermore, the locking element 1510 of the main brush cover 1500 is connected to the locking groove on the surface of the housing 1100, thereby switching the locking element 1510 from the initial state to the mounted state to ensure that the main brush cover 1500 is correctly mounted in the receiving space 1001. Thus, the assembly of the cleaning module 1000 is completed, and the drive assembly 1400 can be started to rotate the roller brush 100 and clean the work surface.

[0067] During normal operation of the cleaning module 1000, the brush body 110 can collect hair and dirt from the work surface. Because the brush body 110 is formed as a conical structure, the dirt caught on the surface of the brush body 110 is conveyed from the first end 111 toward the second end 112 during rotation of the roller brush 100, preventing dirt from entering the interior of the drive assembly of the cleaning module 1000.

[0068] When the roller brush 100 rotates at high speed during normal operation and dirt caught on the surface of the brush body 110 approaches the first end 111, the provision of the deflector plate 130 can effectively prevent dirt from entering the interior of the drive assembly of the cleaning module 1000. To enhance the protection of the interior of the cleaning module 1000, the first locking member 140 is additionally provided. At least a portion of the first locking member 140 and the main brush cover 1500 interfere with each other to prevent hair on the brush body 110 from entering the cleaning module 1000. This ensures the normal operation of the cleaning module 1000 and improves the user experience.
