Description

Technical Field

[0002] As people's living standards improve, more and more families begin to use various cleaning equipment. People's requirements for home cleaning are getting higher and higher. Smart cleaning tools such as household floor scrubbers are becoming more and more popular. Smart floor scrubbers and sweeping robots were born under this trend. At present, floor scrubbers on the market are basically composed of a body and a base station. When working, the floor scrubber uses a fan to suck dirt into the sewage tank, and then uses a roller brush to mop the floor clean, and then put it back to the base station for self-cleaning and charging. After the floor scrubber has been used for a period of time, the roller brush bristles on the machine will be worn to a certain extent. At this time, the cleaning ability of the floor scrubber will be greatly affected, so users need to replace the new roller brush to maintain the cleaning effect. When the roller brush of the floor scrubber in the related technology is replaced, it is often necessary to replace the roller brush together with the assembly bearing, and the consumables cost required for this replacement is relatively high.

[0052] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may be combined with each other.

[0053] The present disclosure provides a cleaning device, which is used to clean a surface to be cleaned. The cleaning device may be a cleaning robot with cleaning functions such as floor washing, sweeping, and mopping. The cleaning device can automatically or semi-automatically move on the surface to be cleaned to clean the surface. Of course, the cleaning device may also be a handheld floor scrubber with cleaning functions such as floor washing, sweeping, and mopping. The user uses the handheld cleaning device to push the cleaning device to move on the surface to be cleaned to clean the surface, which is not limited here. The surface to be cleaned may be the ground, the surface of a carpet, or the surface of other objects to be cleaned.

[0054] The cleaning device disclosed in the present invention includes a main body and functional elements such as a walking mechanism, a dust box, a roller brush module, and a negative pressure generating mechanism arranged on the main body. The walking mechanism is configured to drive the cleaning device to walk on the working surface. The roller brush module is installed on the main body, and under the action of the negative pressure generated by the negative pressure generating mechanism, the dust and other garbage on the working surface to be cleaned is introduced into the dust box through the dust suction port. It should be noted that the main body of the cleaning device and the specific structures of the functional elements such as the walking mechanism, the dust box, and the negative pressure generating mechanism arranged on the main body and the connection relationship between them are no longer limited in this article. The specific structure of the roller brush module and its working principle in coordination with other functional elements are introduced in detail below in conjunction with the accompanying drawings.

[0055] like Figure 1-16As shown, the main structure of the roller brush module 100 provided in the embodiment of the present application includes a support portion 110, a roller brush cylinder 120 and a bearing assembly 130. The roller brush cylinder 120 includes a first connecting portion 121 and a second connecting portion 122 arranged inside the roller brush cylinder 120, and the rotation axis of the roller brush cylinder 120 in the working state is along the first direction; the bearing assembly 130 includes a bearing seat 131 that can be detachably matched with the support portion 110 and a support shaft 132 that is rotatably connected to the bearing seat 131, and the support shaft 132 is formed with a first limiting portion 1321 and a second limiting portion 1322, and the bearing assembly 130 can be inserted axially from the first end of the roller brush cylinder 120 into the roller brush cylinder 120. In the roller brush cylinder 120, the roller brush module 100 has a locked state and an unlocked state; in the locked state, the first limiting portion 1321 and the first connecting portion 121 are rotationally limited, the second limiting portion 1322 and the second connecting portion 122 are axially limited, and the bearing seat 131 is connected to the support portion 110, and the support shaft 132 is coaxially arranged with the roller brush cylinder 120; in the unlocked state, the second limiting portion 1322 and the second connecting portion 122 are released from the axial limit cooperation.

[0056] In the above embodiment, the support portion 110 is connected to the main body 200 of the cleaning device to provide necessary support for the installation and bearing of the roller brush drum 120. A mounting cavity for the roller brush drum 120 is formed on the cleaning device. The brush body roller brush drum 120 of the roller brush module 100 is arranged in the mounting cavity in the working state. The support portion 110 can participate in the formation of the roller brush cavity. The roller brush drum 120 can abut against the surface to be cleaned to clean the surface to be cleaned. Specifically, the roller brush drum 120 can rotate around its own central axis to clean the surface to be cleaned. When the roller brush drum 120 is installed in the working state of the roller brush drum 120, the axial direction of the roller brush drum 120, that is, the extension direction of the rotation axis of the roller brush drum 120 is the first direction X. When the roller brush module 100 is in working state, the bearing seat 131 of the bearing assembly 130 is connected to the support part 110 to provide necessary support for the roller brush module 100, and the roller brush cylinder 120 is coaxially connected to the support shaft 132, so that the roller brush cylinder 120 can rotate around the axis relative to the bearing seat 131.

[0057] The first limiting portion 1321 on the support shaft 132 and the first connecting portion 121 on the roller brush cylinder 120 realize rotation limiting cooperation, which means that the cooperation between the first limiting portion 1321 and the first connecting portion 121 prevents the first roller brush cylinder 120 from relatively rotating around the support shaft 132, without limiting the relative axial movement between the first roller brush cylinder 120 and the support shaft 132. The second limiting portion on the support shaft 132 and the second connecting portion 122 on the roller brush cylinder 120 realize axial limiting cooperation, which means that the cooperation between the first limiting portion 1321 and the first connecting portion 121 prevents the first roller brush cylinder 120 from relatively axially moving with the support shaft 132.

[0058] Through the matching relationship between the first limiting portion 1321 and the first connecting portion 121 , and the matching relationship between the second limiting portion 1322 and the second connecting portion 122 , the roller brush module 100 has a locking state and an unlocking state that can be switched to each other.

[0059] When the cleaning device is working, the roller brush module 100 needs to be in a locked state, at which point it has at least three connection relationships: first, the bearing seat 131 is connected to the support portion 110, and the bearing seat 131 is used to cooperate with the roller brush drum 120 through the support shaft 132; second, the first limiting portion 1321 is rotationally limited with the first connecting portion 121 to achieve that the roller brush drum 120 cannot rotate relative to the support shaft 132, and the two can only rotate synchronously, that is, the roller brush drum 120 and the support column as a whole are relative to the bearing seat. 131 rotation; thirdly, the second limiting portion 1322 cooperates with the second connecting portion 122 in axial limiting, which makes it impossible for the support shaft 132 and the roller brush drum 120 to have axial relative movement, so that the connection relationship between the first limiting portion 1321 and the first connecting portion 121 in the second aspect is maintained, and the roller brush drum 120 cannot be axially displaced relative to the bearing assembly 130. Under the premise that the bearing assembly 130 is fixed to the support portion 110, the roller brush drum 120 cannot be axially displaced relative to the support portion 110. Through the above three aspects of connection relationship, the bearing seat 131 can realize the rotation support function of the roller brush drum 120 in the locked state, so that the roller brush drum 120 can be fixed in the axial direction relative to the support portion 110, and the roller brush drum 120 can be rotated around its own axis, so as to complete the cleaning function.

[0060] When the roller brush barrel 120 needs to be disassembled for cleaning or replacement, the roller brush module 100 needs to be in an unlocked state. At this time, the second limiting portion 1322 and the second connecting portion 122 are released from the axial limiting cooperation, and the axial limiting cooperation between the two is released by external force. At this time, axial relative movement can occur between the support shaft 132 of the bearing assembly 130 and the roller brush barrel 120. When the bearing seat 131 is separated from the connection relationship with the support portion 110, the bearing assembly 130 can be moved axially relative to the roller brush barrel 120, so that the supporting function of the bearing assembly 130 for the roller brush barrel 120 is released, so that the roller brush barrel 120 can be disassembled, and the bearing assembly 130 and the roller brush barrel 120 are separated from each other. The user only needs to replace the roller brush barrel 120, and the bearing assembly 130 can continue to be used.

[0061] When the user needs to install the cleaned roller brush drum 120 or a new roller brush drum 120, it is a process of converting the roller brush module 100 from an unlocked state to a locked state. At this time, the support column of the bearing assembly 130 extends axially into the roller brush drum 120, first making the first limiting portion 1321 and the first connecting portion 121 complete the rotational limiting cooperation, and then making the second limiting portion 1322 and the second connecting portion 122 complete the axial limiting cooperation, and the bearing seat 131 is connected to the support portion 110, so that the bearing seat 131 rotatably supports the roller brush drum 120, the roller brush drum 120 can be fixed in the axial direction relative to the support portion 110, and the roller brush drum 120 can be rotated around its own axis, and the roller brush module 100 is in a locked state.

[0062] The roller brush barrel 120 is detachably connected to the first limiting portion 1321 and the second limiting portion 1322 of the bearing assembly 130 through the first connecting portion 121 and the second connecting portion 122 inside the roller brush barrel 120. The first limiting portion 1321 can limit the relative rotation between the roller brush barrel 120 and the support shaft 132, but does not limit the axial movement. The second limiting portion 1322 can limit the axial movement between the roller brush barrel 120 and the support shaft 132 to ensure stability in the working state. This design allows the roller brush barrel 120 to operate stably in the locked state, and in the unlocked state, the above-mentioned limiting matching relationship can be released by external force, thereby separating the roller brush barrel 120 from the bearing assembly 130.

[0063] When the brush barrel 120 is worn out due to long-term use, the cleaning effect is reduced or other damage occurs, it only needs to be disassembled and separated from the bearing assembly 130 and replaced with a new brush barrel 120, without replacing the overall structure, including the bearing assembly 130. The brush barrel 120 is a cleaning component, and its manufacturing cost is relatively low compared to the bearing assembly 130. The bearing assembly 130 contains precision mechanical components, such as a bearing seat 131 and a support shaft 132. These components have a long design life, are not easy to damage, and are expensive. The design of independent disassembly and assembly avoids unnecessary waste, and only the vulnerable brush barrel 120 needs to be replaced. That is, in the embodiment of the present disclosure, the design of the brush barrel module 100 significantly optimizes the use efficiency of consumables. By realizing the separate replacement of the brush barrel 120 and the bearing assembly 130, the user only needs to replace the brush barrel 120 in daily maintenance, without replacing the bearing assembly 130. This innovative design significantly reduces the cost of consumables.

[0064] In some embodiments, Figure 1-3 and Fig. 9 As shown, a limiting hole 123 is formed on the first connection part 121 and extends in the axial direction of the roller brush cylinder 120. The first limiting part 1321 is a flat shaft section formed at one end of the support shaft 132 away from the bearing seat 131, and the flat shaft section can be inserted into or removed from the limiting hole 123 in the axial direction. The limiting hole 123 is formed on the first connection part 121 of the roller brush cylinder 120, passes through the connection part, and extends in the axial direction of the roller brush cylinder 120, ensuring that the support shaft 132 can be inserted or pulled out in the axial direction when installing or disassembling. The existence of the limiting hole 123 provides guidance and support for the fixation of the support shaft 132, avoiding axial misalignment of the roller brush cylinder 120 during operation. The first limiting part 1321 is designed as a flat shaft section at one end of the support shaft 132 away from the bearing seat 131. This shape is conducive to achieving a stable limiting fit when inserting the limiting hole 123. In the installed state, the flat shaft section is inserted into the limiting hole 123 and forms a limiting fit with the limiting hole 123, thereby limiting the relative movement of the roller brush barrel 120 and the support shaft 132 in the rotation direction, ensuring that the roller brush barrel 120 rotates synchronously around the central axis of the support shaft 132. In the disassembled state, by applying an external force in the axial direction, the flat shaft section is withdrawn from the limiting hole 123, and the roller brush barrel 120 can be separated from the support shaft 132, thereby realizing the rapid replacement or cleaning operation of the roller brush barrel 120.

[0065] The cooperation between the limiting hole 123 and the flat shaft segment is mainly used to limit the rotational movement of the roller brush barrel 120 relative to the support shaft 132. After the flat shaft segment is inserted into the limiting hole 123, its special geometric shape (flat surface) is in close contact with the inner wall of the limiting hole 123, preventing the roller brush barrel 120 from rotating relative to the support shaft 132, ensuring that the two can rotate synchronously. The limiting hole 123 is set through, allowing the flat shaft segment to be freely inserted or withdrawn in the axial direction, so it will not limit the axial displacement of the roller brush barrel 120 relative to the support shaft 132. Through this matching design, it is convenient for users to quickly disassemble or install the roller brush barrel 120 while meeting the rotation limit requirements, thereby improving operational convenience and maintenance efficiency.

[0066] In some embodiments, Fig. 9 As shown, the second connecting portion 122 is an elastic clip provided on the roller brush barrel 120, and the second limiting portion 1322 can be a snap-in groove formed at one end of the flat shaft section away from the bearing seat 131. In the locked state, the flat shaft section passes through the limiting hole 123 and the snap-in groove is snap-fitted with the elastic clip. The elastic clip has a certain elastic deformation ability and can be snap-fitted with the limiting groove. The snap-in groove is formed at the far end of the flat shaft section, and is used to snap-fit ​​with the elastic clip on the roller brush barrel 120, thereby limiting the axial movement of the roller brush barrel 120.

[0067] The user aligns the flat shaft section of the support shaft 132 with the limiting hole 123 on the first connecting portion 121 of the roller brush barrel 120, and pushes the flat shaft section into the limiting hole 123 along the axial direction of the roller brush barrel 120, so that the flat shaft section passes through the limiting hole 123, and the far end of the flat shaft section provided with the clamping groove passes through the limiting hole 123 and then passes out from the other end of the limiting hole 123. After passing out, the end of the flat shaft section interferes with the elastic clamping strip, and the elastic clamping strip automatically embeds into the clamping groove due to its elastic deformation characteristics to achieve a clamping fit. Due to the clamping fit between the elastic clamping strip and the clamping groove, the roller brush barrel 120 is fixed relative to the support column in the axial direction to prevent relative displacement, thereby ensuring the stability of the overall structure. When it is necessary to release the engagement between the elastic clip and the engaging groove, the support shaft 132 is moved axially in the reverse direction so that the flat shaft section interferes with the elastic clip in the axial direction, causing the elastic clip to fall out of the engaging groove, thereby releasing the engaging engagement between the two. After releasing the engaging engagement, the user pulls the roller brush or bearing assembly 130 along the axial direction of the roller brush barrel 120 to move the flat shaft section out of the limiting hole 123, thereby completing the separation of the roller brush barrel 120 and the support shaft 132.

[0068] Optional, such as Figure 4As shown, the elastic clip strip is a U-shaped structure, which includes two elastic arms 1221 arranged side by side, and the two elastic arms 1221 are connected by a connecting arm 1222. The middle section of the elastic arm 1221 is bent and brought close to each other to form two parallel clip sections 1223. The clip groove is clipped with the two clip sections 1223, thereby limiting the axial displacement of the roller brush cylinder 120. The U-shaped structure is fixed to the inner wall of the roller brush cylinder 120 through the connecting arm 1222, ensuring that the elastic clip strip is firmly installed on the roller brush cylinder 120, and the plane where the elastic clip strip is located is perpendicular to the axial direction of the roller brush cylinder 120, ensuring that the clip groove and the clip section 1223 can be effectively clipped, thereby limiting the axial movement of the roller brush cylinder 120. After the distal end of the flat shaft segment passes through the limiting hole 123, it will contact the clamping section 1223 of the elastic clamping strip. As the flat shaft segment continues to move axially, the end of the flat shaft segment interferes with the clamping section 1223, which stretches the two clamping sections 1223 and causes them to deform to a certain extent. When the axial movement continues, the clamping groove moves to the position of the clamping section 1223, and the clamping section 1223 is finally embedded in the clamping groove under the action of the elastic reset force, forming a stable clamping fit. This design uses the elastic deformation of the elastic clamping strip to enable the flat shaft segment to achieve effective cooperation with the clamping groove. When the clamping section 1223 is embedded in the clamping groove, the elastic force of the elastic clamping strip can firmly limit the axial movement of the roller brush barrel 120, thereby ensuring that the roller brush module 100 maintains a stable connection state during operation. When the snap-fit ​​needs to be released, it is only necessary to provide a reverse axial force to the support column, and the snap-fit ​​groove will interfere axially with the snap-fit ​​section 1223 of the elastic clip. Under the interference, the two snap-fit ​​sections 1223 are stretched open and disengaged from the snap-fit ​​groove, and continue to move axially in the opposite direction, and the flat shaft section finally breaks away from the contact with the elastic clip. This design utilizes the elastic deformation of the elastic clip to enable the flat shaft section to achieve effective cooperation with the snap-fit ​​groove. When the snap-fit ​​section 1223 is embedded in the snap-fit ​​groove, the elastic force of the elastic clip can firmly limit the axial movement of the roller brush barrel 120, thereby ensuring that the roller brush module 100 maintains a stable connection state during operation.

[0069] In some embodiments, in the locked state, the flat shaft segment passes through the limiting hole 123 and the first connection portion 121 is clamped between the elastic clip and the bearing seat 131. When the flat shaft segment passes through the limiting hole 123 and the elastic clip is engaged with the engaging groove, one side of the first connection portion 121 is pressed by the elastic clip, and the bearing seat 131 is pressed with the other side of the first connection portion 121, ensuring that the first connection portion 121 cannot be axially displaced, ensuring that the roller brush barrel 120 can remain fixed in the working state, and avoiding unnecessary movement or loosening. This design not only enhances the stability of the roller brush module 100, but also simplifies the structure, making it more convenient to disassemble and replace the roller brush barrel 120. Through this locked state, the cooperation of the flat shaft segment and the elastic clip can effectively prevent the relative movement between the roller brush barrel 120 and the support shaft 132, thereby ensuring the reliability and efficiency of the equipment during operation.

[0070] In the above embodiments, the user needs to forcefully pull out the bearing assembly 130 from the roller brush barrel 120 to release the snap-fitting between the elastic cartoon and the snap-fitting groove. Although this replacement method reduces the cost of consumables, it requires the user to forcefully disassemble and assemble, which is not convenient enough, and there is also a situation where the consumables are damaged due to violent disassembly and assembly. Therefore, a roller brush module 100 is needed that can meet the low cost of roller brush consumable replacement and is convenient for disassembly and assembly. Based on this, in some embodiments, a first threaded portion 1311 is provided on the bearing seat 131, and a second threaded portion 1121 is provided on the support portion 110. During the process of the first threaded portion 1311 and the second threaded portion 1121 being threadedly connected and rotating, the bearing assembly 130 moves along a first direction relative to the support portion 110, so that the roller brush module 100 switches between the unlocked state and the locked state.

[0071] like Figure 1-3 As shown, the bearing seat 131 is an important component of the roller brush module 100, and is used to be installed on the support part 110 of the cleaning equipment. A first threaded portion 1311 is provided on the bearing seat 131, and the support part 110 is fixed on the main body 200 of the cleaning equipment. A second threaded portion 1121 is provided on the support part 110. The first threaded portion 1311 is threadedly matched with the second threaded portion 1121. The roller brush module 100 can be locked and unlocked by rotating the bearing seat 131 or the support part 110.

[0072] During the installation of the roller brush cylinder 120, the user aligns the bearing assembly 130 with the roller brush cylinder 120, inserts the flat shaft segment into the limiting hole 123 of the roller brush cylinder 120, and the first threaded portion 1311 and the second threaded portion 1121 are threadedly connected to each other and rotate in one direction (such as clockwise). The bearing seat 131 moves axially to push the flat shaft segment of the support shaft 132 into the limiting hole 123 in the roller brush cylinder 120 until the elastic clip and the clip groove are fully engaged, thereby completing the fixation of the roller brush cylinder 120 and obtaining a locked state. In the locked state, the roller brush module 100 can work normally, and the rotational movement of the roller brush cylinder 120 is stable and reliable.

[0073] During the process of disassembling the roller brush barrel 120, when the user spirally rotates the first threaded portion 1311 and the second threaded portion 1121 in opposite directions (such as counterclockwise), the bearing seat 131 moves in the opposite axial direction during this process, so that the clamping state between the elastic clamping strip and the clamping groove is released, and the flat shaft section gradually disengages from the limiting hole 123. When the threaded connection between the first threaded portion 1311 and the second threaded portion 1121 is completely disengaged, the bearing seat 131 is disengaged from the support portion 110. The user can easily pull the bearing assembly 130 out of the roller brush barrel 120 without exerting force, and can easily disassemble the roller brush module 100 for cleaning or replacement.

[0074] The user can lock and unlock the roller brush module 100 by simply rotating the screw connection, which greatly improves the convenience of operation and avoids the user from pulling out the roller brush barrel 120 with force, making the operation more convenient. The connection and release process between the elastic clip and the clip groove is completed by the screw connection structure, which avoids damage to the roller brush barrel 120 or the elastic clip due to violent disassembly. The replacement and cleaning process of the roller brush barrel 120 is easier and faster, meeting the user's high-frequency replacement needs.

[0075] In some embodiments, Figure 6-7 and Figure 10-14 As shown, the roller brush module 100 further includes a driving assembly 140, the supporting portion 110 includes a supporting plate 111 and a rotating member 112 rotatably disposed on the supporting plate 111, the second screw connection portion 1121 is disposed on the rotating member 112, and the driving assembly 140 is configured to drive the rotating member 112 to rotate. In order to further simplify the disassembly and assembly operation of the roller brush module 100 and avoid the user manually rotating the screw connection portion, the driving assembly 140 is introduced in this embodiment. The driving assembly 140 can automatically drive the rotating member 112 to rotate, perform the screw connection process between the first screw connection portion 1311 and the second screw connection portion 1121, and realize the switching of the roller brush module 100 between the locked state and the unlocked state, making the user operation more convenient.

[0076] The support plate 111 is fixed on the cleaning device body 200 and is used to carry other components of the roller brush module 100. The support plate 111 is further arranged at one axial end of the roller brush cylinder 120 and is used to set the bearing assembly 130 to cooperate with this end of the roller brush cylinder 120. During the disassembly process, when the bearing assembly 130 moves axially, due to the cooperation between the elastic clip and the clip groove, the bearing seat 131 will drive the roller brush cylinder 120 to move axially together. When the end of the roller brush cylinder 120 moves to the position of the support plate 111, the support plate 111 will play a blocking role and limit the roller brush cylinder 120 from continuing to move axially. At this time, the bearing assembly 130 will gradually generate interference force between the elastic clip and the clip groove during the process of continuing axial movement, and finally the elastic clip and the clip groove will be out of the clipping cooperation, so as to achieve the unlocked state of the roller brush cylinder 120.

[0077] When the roller brush cylinder 120 needs to be installed, the user aligns the support shaft 132 with the roller brush cylinder 120, inserts the flat shaft segment into the roller brush cylinder 120, starts the drive assembly 140, and the drive assembly 140 drives the rotating member 112 to rotate. The second threaded portion 1121 and the first threaded portion 1311 begin to threadably engage with each other. The rotation of the rotating member 112 pushes the bearing assembly 130 to move axially, and the flat shaft segment is gradually inserted into the roller brush cylinder 120 until the elastic clip is snapped into the snap-in groove. When the roller brush needs to be removed, the user starts the driving assembly 140, and the driving assembly 140 drives the rotating member 112 to rotate in the reverse direction. As the rotating member 112 rotates, the bearing assembly 130 moves in the reverse axial direction under the threaded cooperation between the second threaded portion 1121 and the first threaded portion 1311, and the engagement between the elastic clip and the engagement groove is released, and the roller brush barrel 120 is disengaged from the support shaft 132. After the second threaded portion 1121 is disengaged from the first threaded portion 1311, the user can easily remove the bearing assembly 130 and the roller brush barrel 120.

[0078] The user only needs to press the control button to start the drive component 140 to complete the disassembly and assembly of the roller brush module 100, which makes the operation more convenient; it reduces the user's manual operation, which is especially suitable for users with less strength or who are not good at operating the screw structure. The drive component 140 can accurately control the rotation speed and torque of the rotating part 112 to avoid damage caused by excessive force during manual operation.

[0079] In some embodiments, the rotating member 112 is a gear structure, and the driving assembly 140 includes a gear motor 141 and a first linkage gear 142, and the first linkage gear 142 is meshed and connected with the output gear of the gear motor 141 and the rotating member 112 respectively. Gear transmission can achieve efficient power transmission, ensure the stable rotation of the rotating member 112, and improve the structural reliability and operational convenience of the system. The gear motor 141 provides rotational power, and an output gear is connected to its output end. The first linkage gear 142 is located between the output gear and the rotating member 112 for transmitting power. The output gear of the gear motor 141 is meshed and connected with the first linkage gear 142, and the first linkage gear 142 is also meshed and connected with the rotating member 112 (gear structure) to form a stable power transmission chain.

[0080] During the installation process, the user aligns the bearing seat 131 with the roller brush cylinder 120, inserts the flat shaft section into the limiting hole 123 in the roller brush cylinder 120, starts the gear motor 141, drives the output gear to rotate, and the output gear drives the first linkage gear 142 to rotate. The first linkage gear 142 further drives the rotating member 112 to rotate. The rotation of the rotating member 112 drives the bearing assembly 130 to move axially, and the flat shaft section is gradually inserted into the roller brush cylinder 120, and the elastic clip is connected with the clip groove.

[0081] During the disassembly process, the user starts the reverse operation function of the drive assembly 140, the gear motor 141 drives the output gear to rotate in reverse, the power is transmitted to the rotating member 112 through the first linkage gear 142, the rotating member 112 rotates in the reverse direction, and the bearing assembly 130 moves along the reverse axial direction, gradually releasing the engagement between the elastic clip and the engagement groove, and after the threaded connection between the rotating member 112 and the bearing seat 131 is released, the user can easily remove the bearing assembly 130 and the roller brush barrel 120.

[0082] By designing the rotating member 112 as a gear structure and introducing a combination of a gear motor 141 and a linkage gear, this embodiment further optimizes the disassembly and assembly efficiency of the roller brush module 100. The gear transmission structure not only improves the power transmission efficiency, but also greatly improves the automation and operation convenience of the roller brush module 100. The gear motor 141 and the gear transmission assembly are integrated, occupying a small space and suitable for embedded installation.

[0083] In some embodiments, the first threaded portion 1311 is an external thread provided on the bearing seat 131, and the second threaded portion 1121 is an internal thread provided on the rotating portion. By designing the external thread on the bearing seat 131 and the internal thread on the rotating portion to cooperate, a reliable connection between the roller brush barrel 120 and the support portion 110 is achieved, and at the same time, the driving assembly 140 drives the rotating portion to rotate, and the locking or unlocking operation of the roller brush module 100 is completed, which can effectively solve the problem of operational convenience during the locking and unlocking process of the roller brush module 100.

[0084] The first threaded portion 1311 is an external thread provided on the outer surface of the bearing seat 131, and the pitch and size of the external thread are designed according to the specifications of the roller brush module 100 to ensure accurate matching with the second threaded portion 1121. The second threaded portion 1121 is an internal thread provided on the inner surface of the rotating portion, and the internal thread and the external thread have the same thread parameters, so that reliable thread engagement can be formed.

[0085] During the installation process, the roller brush is located on the inner side of the support plate 111. The user first inserts the bearing assembly 130 from the outer side of the support plate 111 through the through hole inside the rotating part, and inserts the roller brush cylinder 120 axially. The flat shaft section is inserted into the limiting hole 123. The external thread of the bearing seat 131 is aligned with the internal thread of the rotating part. The gear motor 141 of the drive assembly 140 is started to drive the rotating part to rotate. The internal thread gradually engages along the external thread. The rotation of the rotating part causes the bearing seat 131 to move axially. The roller brush cylinder 120 is locked by the coupling groove and the elastic clip strip. During the disassembly process, the user starts the gear motor 141 of the drive assembly 140 to run in reverse, the rotating part rotates in the opposite direction, and the external thread and the internal thread gradually disengage. In this process, the bearing seat 131 moves axially, and the elastic clip strip and the coupling groove are released. After the external thread and the internal thread disengage, the user can easily remove the bearing assembly 130 and the roller brush cylinder 120.

[0086] Through the cooperation of the external thread and the internal thread, the roller brush cylinder 120 can be stably locked and unlocked to prevent loosening during operation. The threaded connection method can achieve precise control of axial movement and ensure the stability of the roller brush module 100 during locking and unlocking.

[0087] In some embodiments, a third limiting portion 1312 is provided on the bearing seat 131, and a fourth limiting portion 123 is provided in the roller brush cylinder 120, and the third limiting portion 1312 and the fourth limiting portion 123 are slidably matched along the first direction. The third limiting portion 1312 is provided on the outer surface of the bearing seat 131, and may be a guide groove or guide rib extending in the axial direction, and the size and shape of the third limiting portion 1312 are designed according to the matching requirements of the fourth limiting portion 123 in the roller brush cylinder 120. The fourth limiting portion 123 is provided on the inner wall of the roller brush cylinder 120, and may be a guide rib or guide groove matching the third limiting portion 1312. There is a precise sliding gap between the third limiting portion 1312 and the fourth limiting portion 123, which can allow the roller brush cylinder 120 to slide freely in the axial direction, and limit the displacement of the roller brush cylinder 120 in the radial and rotational directions.

[0088] By designing the third limiting portion 1312 on the bearing seat 131 and the fourth limiting portion 123 in the roller brush cylinder 120, the two form a sliding fit along the first direction, and this fit can effectively guide and constrain the movement trajectory of the bearing seat 131, avoiding jamming or wear caused by offset during movement. At the same time, the matching structure of the third limiting portion 1312 and the fourth limiting portion 123 can also assist in smoothly and reliably converting the rotational motion of the rotating member 112 into the axial linear motion of the bearing seat 131 through the screw connection structure, ensuring the smooth switching of the roller brush module 100 between the unlocked state and the locked state, thereby improving the efficiency and reliability of the entire assembly process.

[0089] In some embodiments, the bearing assembly 130 also includes an end cover 133 connected to the bearing seat 131, and the end cover 133 and the first limiting portion 1321 are respectively located on both sides of the bearing seat 131, and the end cover 133 protrudes from the bearing seat 131 in at least one axial direction perpendicular to the support shaft 132.

[0090] During the process of screwing and rotating, the bearing seat 131 is inserted into the roller brush barrel 120 through the through hole of the rotating part. As the first screwing part 1311 and the second screwing part 1121 are gradually tightened, the end cover 133 can abut against the outer side of the rotating part or the support plate 111, so that the edge area of ​​the end cover 133 can play an auxiliary positioning or protection role during installation or disassembly, effectively preventing the bearing seat 131 from over-rotating due to excessive screwing.

[0091] In some embodiments, the roller brush module 100 also includes a roller brush motor 150, a first plug-in portion 151 is formed on the output shaft of the roller brush motor 150, a second plug-in portion 124 is provided in the roller brush cylinder 120, and the bearing assembly 130 can be axially inserted into the roller brush cylinder 120 from the second end of the roller brush cylinder 120 so that the first plug-in portion 151 is plug-fitted with the second plug-in portion 124.

[0092] The second plug-in portion 124 is an axial hole opened in the roller brush cylinder 120, and a spline 1511 groove is arranged on the hole wall of the axial hole. The first plug-in portion 151 is a shaft body arranged at the output end of the roller brush motor 150, and a spline 1511 is arranged on the surface of the shaft body, and the spline 1511 is adapted to the spline 1511 groove. In this embodiment, the shape and size of the shaft hole as the second plug-in portion 124 are generally adapted to its required application to accommodate the shaft body as the first plug-in portion 151, and the shape and size of the spline 1511 on the shaft body match the spline 1511 groove in the shaft hole to ensure that they can be plugged into each other and can transmit force or torque in the circumferential direction. During the connection process, the first plug-in portion 151 and the second plug-in portion 124 are aligned with each other so that the spline 1511 groove and the spline 1511 fit each other. This interlocking mechanism ensures the stability and reliability of the connection. Once the plug-in is completed, the first plug-in portion 151 and the second plug-in portion 124 will form a stable connection, allowing the transmission of force or torque. The roller brush motor 150 is a structure that provides power for the rotation of the roller brush barrel 120.

[0093] In some embodiments, the roller brush module 100 further includes a motor fixing assembly 160, which is used to be connected to the body of the cleaning device. The motor fixing assembly 160 has a first pivoting portion 161, and a second pivoting portion 152 is provided at one end of the roller brush motor 150 away from the output shaft, and the first pivoting portion 161 and the second pivoting portion 152 are rotatably connected through the first pivot 162. The first pivoting portion 161 and the second pivoting portion 152 are rotatably connected through the first pivot 162, which can realize a large range of movement of the roller brush motor 150 and the roller brush cylinder 120, thereby increasing the space for cleaning operation or disassembly. When the bearing assembly 130 is removed, the roller brush cylinder 120 can be moved axially, thereby causing the rotation area of ​​the first pivoting portion 161 and the second pivoting portion 152 to leak out of the roller brush cylinder 120. At this time, the roller brush cylinder 120 and the roller brush motor 150 can rotate as a whole, thereby providing a larger disassembly space or cleaning operation space. This design not only improves the maintenance convenience of the equipment, but also improves the operational flexibility during the cleaning process, making it easier for users to clean or replace the equipment, and avoiding the inconvenience caused by limited space.

[0094] In some embodiments, the motor fixing assembly 160 includes a fixing plate 163, a sealing end portion 164 and a first pivot portion 161, the sealing end portion 164 is connected to the fixing plate 163 and is used to seal the second end of the roller brush, the sealing end portion 164 is axially arranged at an angle to the fixing plate 163, the first pivot portion 161 is arranged on the side of the sealing end portion 164 away from the fixing plate 163, and a third pivot portion 165 is arranged on the fixing plate 163, and the third pivot portion 165 is used to be rotatably connected to the machine body through a second pivot 166. The axial direction of the sealing end portion 164 is set at an angle with the fixed plate 163, which can allow the fixed plate 163 to be fitted on the side wall of the body. This arrangement helps to optimize space utilization. The sealing end portion 164 can reduce the entry of dust, large particles and other substances into the roller brush drum 120. The third pivot portion 165 is rotatably connected to the body of the cleaning device through the second pivot 166, which can further increase the rotation space of the roller brush drum 120 and the roller brush motor 150, increase the operating space during cleaning operations or disassembly, and help to improve the overall operability and maintenance efficiency of the equipment.

[0095] Preferably, the first pivot 162 and the second pivot 166 are arranged in parallel. The parallel arrangement of the two pivots can ensure that the two rotation trajectories are located in the same plane, thereby maximizing the superposition effect of the rotation range and obtaining a sufficiently large rotation range. Preferably, the first pivot 162 and the second pivot 166 are both arranged vertically so that the rotation range is mainly concentrated in the horizontal plane. This arrangement avoids rotation interference in the vertical direction and is particularly suitable for operations of cleaning the floor and waiting for the cleaning surface, because objects or obstacles on the ground usually affect the vertical rotation. By arranging the pivots in parallel and ensuring that the rotation range is in the horizontal plane, greater flexibility and convenient operating space can be ensured during the cleaning process.

[0096] It should be noted that the fixed plate 163 is connected to the body by limiting components such as snaps. During the operation of the roller brush module 100, the fixed plate 163 is fixedly connected to the body to prevent the fixed plate 163 from rotating around the second pivot 166 and affecting the stability of the installation of the roller brush motor 150 and the roller brush cylinder 120. When disassembly is required, the fixed connection between the fixed plate 163 and the body can be released, and the fixed plate 163 can rotate around the second pivot 166.

[0097] like Figure 10-16As shown, the cleaning device also includes a scraper assembly 300, and the scraper assembly 300 includes a scraper 310 extending along the first direction. The scraper 310 is interference-fitted with the roller brush drum 120 to scrape off the sewage or dirt on the roller brush drum 120 during operation. However, the interference fit between the scraper 310 and the roller brush drum 120 is not convenient for cleaning after the work is completed. A large amount of residual dirt is sandwiched between the scraper 310 and the roller brush drum 120, which cannot be cleaned up during the self-cleaning process and needs to be cleaned manually. Based on this, in some embodiments, the scraper assembly 300 of the cleaning device also includes a second linkage gear 320 arranged at one end of the scraper 310, and the rotation axis of the second linkage gear 320 is also along the first direction. The first linkage gear 142 is meshed with the second linkage gear 320 through a third linkage gear 330. During the rotation of the second linkage gear 320, the scraper 310 has a third linkage gear 330 that is in contact with the roller brush drum 120. Fig.16 The first state shown and the interference fit with the roller brush cylinder 120 are as shown in FIG. Fig.15 The second state shown. When the cleaning device is put back to the base station and self-cleaning is turned on, the gear motor 141 will run the self-cleaning stroke, so that the scraper 310 and the roller brush 120 change from an interference state to a fitting state, and then the self-cleaning program starts the water pump to flush the residual dirt on the scraper with a large amount of water and cooperate with the roller brush 120 to brush, thereby achieving self-cleaning of the dirt on the scraper.

[0098] When the second linkage gear 320 of the linkage scraper bar rotates, since the rotation range between the second interference state and the first fit state is very small, the fastening and assembly of the bearing seat 131 will not be affected by the rotation of the gear motor 141 .

[0099] Preferably, the second linkage gear 320 is a half gear, so when the roller brush cylinder 120 is replaced, this design can avoid the gear motor 141 from having a significant impact on the assembly position of the scraper strip through the rotation stroke of the first linkage gear 142 and the third linkage gear 330 when the roller brush cylinder 120 is replaced. Since the half gear only covers the necessary area within the rotation range of the scraper 310, the large rotation stroke of the gear motor 141 will not cause a significant displacement of the assembly position of the scraper 310 during self-cleaning or replacement of the roller brush cylinder 120. This design ensures that the scraper 310 always maintains a stable assembly state during operation, and can effectively avoid the problem of looseness or inaccuracy of the scraper 310 caused by excessive gear rotation. The setting range of the teeth in the half gear is adapted to the rotation range of the scraper 310.

[0100] The present application also protects a cleaning device accordingly, which includes a main body 200 and a roller brush module 100 provided in the above-mentioned embodiment. In some embodiments, the cleaning device is a floor scrubber, and the main body 200 includes a body 210 and a base 220, the body 210 is rotatably connected to the base 220, and the roller brush module 100 and the scraper assembly 300 are arranged on the base 220. The body 210 is roughly a rectangular parallelepiped, and of course it can also be other shapes such as a cylinder. The body 210 is usually provided with a power device for generating cleaning power and an energy storage device for providing energy. Of course, in different embodiments, the power device and the energy storage device can also be arranged on other components of the cleaning device, such as the base 220. The base 220 and the handle 400 are respectively provided at both ends along the extension direction of the body 210. The base 220 is arranged at one end of the body 210 close to the surface to be cleaned, and the base 220 can move on the surface to be cleaned, so as to clean the surface to be cleaned. The walking wheel 500 is arranged on the base 220 and contacts the surface to be cleaned. It is configured to drive the base 220 to move on the surface to be cleaned and provide rolling friction to reduce resistance. The handle 400 for the user to hold and operate is arranged at the end of the body 210 away from the surface to be cleaned, so that the handle 400 is at a certain height from the surface to be cleaned in most cases, so that the user does not need to bend over to operate, thereby improving the comfort of operation. In order to further improve the comfort of different users and take into account different usage conditions, the body 210 can rotate relative to the base 220, thereby changing the angle between the body 210 and the base 220 and the height of the body 210 from the ground.

[0101] In some embodiments, the cleaning device further includes a base station, which is used to place the base 220. Specifically, the base station is designed as an auxiliary accessory of the cleaning device, which is used to store the base 220 and provide additional functions. For example, when the cleaning device is not in use, the base station can be used as a fixed parking position to keep the device tidy and storage stable. In addition, the base station can also integrate other functions, such as self-cleaning, charging or maintenance support. In the self-cleaning function, a cleaning liquid container and a drainage structure may be provided inside the base station. When the base 220 is placed on the base station, the base station can supply cleaning liquid to components such as the roller brush module 100 and the scraper assembly of the cleaning device to complete efficient cleaning. Through this design, the cleaning device can not only complete the cleaning task of the ground, but also realize its own efficient cleaning and maintenance through the base station, extend the service life of the equipment and reduce the user's operating burden, further expand the functions and application scenarios of the cleaning device, and enhance the user's experience.
