Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a roller brush mounting structure and cleaning equipment. Background Technology

[0002] In cleaning equipment, long fibers and other foreign objects easily become entangled on the surface of the roller brush and intrude into the gap between the roller brush shaft and the side cover, leading to frequent equipment malfunctions. Long-term accumulation of uncleaned fibers exacerbates friction and can even cause the roller brush shaft or side cover to deform and be damaged due to high temperatures. Therefore, it is necessary to periodically separate the roller brush shaft from the side cover and clean the entangled foreign objects. However, separating the roller brush shaft from the side cover of these cleaning devices usually requires specialized tools and a certain level of professional skill, which significantly impacts maintenance efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a roller brush mounting structure and cleaning equipment that is easy to maintain in order to address the above problems.

[0004] This application provides a roller brush mounting structure, which includes:

[0005] A roller brush shaft, one end of which is used for transmission connection with the drive shaft of the cleaning equipment, and the other end of which is provided with a plug hole;

[0006] An end cap assembly, the end cap assembly including a locking mechanism, a side cover and a plug-in cylinder, the side cover being disposed on the plug-in hole and used for connection with the device body of the cleaning equipment, the plug-in cylinder being rotatably disposed through the side cover and capable of being inserted into the plug-in hole;

[0007] A locking mechanism is provided in the insertion hole and the insertion cylinder, and the locking mechanism can fix or separate the brush shaft from the insertion cylinder.

[0008] The roller brush mounting structure described above achieves at least the following beneficial effects: the roller brush shaft and end cap assembly of this mounting structure achieve convenient locking and unlocking functions through a locking mechanism. When the locking mechanism is locked, the insertion tube can be relatively fixed to the roller brush shaft through the locking mechanism, forming a stable connection between the insertion tube and the roller brush shaft, ensuring that the roller brush shaft will not undergo relative displacement with the insertion tube during rotation. When disassembly is required, the locking mechanism can be unlocked, and the insertion tube can be separated from the roller brush shaft and pulled out from the insertion hole. The entire process can be completed without the aid of tools, ensuring the reliability of the connection when the roller brush shaft rotates, and achieving the convenience of quick assembly and disassembly.

[0009] In some embodiments, the locking mechanism includes a snap-fit ​​groove, a locking member, and an adjusting member. The snap-fit ​​groove is formed by an indentation in the wall of the insertion hole. A through hole is provided in the wall of the insertion cylinder. The locking member is movably disposed in the through hole. The adjusting member is inserted into the insertion cylinder and can move relative to the insertion cylinder to a locked position and an unlocked position. In the locked position, the locking member can extend into the snap-fit ​​groove under the drive of the adjusting member to fix the roller brush shaft and the insertion cylinder relatively. In the unlocked position, the locking member can exit the snap-fit ​​groove to separate the roller brush shaft from the insertion cylinder relatively. This roller brush mounting structure achieves convenient locking and unlocking functions through the cooperation of the roller brush shaft and the end cap assembly. One end of the roller brush shaft has a locking groove in its insertion hole. When the insertion sleeve of the end cap assembly is inserted into the insertion hole, the movement of the adjusting component within the insertion sleeve drives the locking component to move radially within the through hole. When the adjusting component moves to the locked position, it pushes the locking component outward and locks into the locking groove of the roller brush shaft, forming a stable connection between the insertion sleeve and the roller brush shaft. This ensures that the roller brush shaft will not have relative displacement with the insertion sleeve during rotation. When disassembly is required, the adjusting component moves to the unlocked position, causing a change in the contact surface with the locking component. This causes the locking component to lose radial support and exit the locking groove. At this point, the insertion sleeve and the roller brush shaft are unlocked and can be easily separated. The entire process can be completed without tools, ensuring reliable connection during roller brush shaft rotation and providing convenient quick assembly and disassembly. This is particularly suitable for cleaning equipment requiring frequent cleaning and maintenance.

[0010] In some embodiments, the adjusting member is rod-shaped and telescopically inserted into the insert cylinder, with a pressing portion protruding from its outer circumferential surface. In the locked position, the locking member can extend into the snap-fit ​​groove under the pressure of the pressing portion. In the unlocked position, the pressing portion and the locking member are misaligned so that the locking member can exit the snap-fit ​​groove. The adjusting member is axially telescopically inserted into the insert cylinder and has a pressing portion on its outer circumferential surface. When the adjusting member moves to the locked position, its pressing portion aligns with the locking member and applies radial pressing force, forcing the locking member to extend outward along the through hole and embed into the snap-fit ​​groove of the roller brush shaft. At this time, the insert cylinder and the roller brush shaft form a rigid connection. When the adjusting member moves axially to the unlocked position, the pressing portion and the locking member are circumferentially misaligned, the locking member loses the radial pressing force and can retract under the constraint of the inner wall of the insert cylinder to completely disengage from the snap-fit ​​groove, thus unlocking the roller brush shaft from the insert cylinder.

[0011] In some embodiments, the end cap assembly further includes a fixing cap and an elastic member. The fixing cap is located at one end of the insertion tube for insertion into the insertion hole. The elastic member is located inside the insertion tube. One end of the elastic member is connected to the fixing cap, and the other end of the elastic member is connected to the adjusting member. The adjusting member can move to the locked position under the elastic force of the elastic member, and the adjusting member can also overcome the elastic force of the elastic member under the action of an external force to move to the unlocked position. An elastic reset mechanism is constructed by adding a fixed cover and an elastic element inside the insert cylinder. The fixed cover is fixed to one end of the insert cylinder that is inserted into the insert hole to form a limiting structure. The two ends of the elastic element are connected to the fixed cover and the adjusting element, respectively. Under natural conditions, the adjusting element is automatically locked by the elastic force of the elastic element. At this time, the squeezing part of the adjusting element continuously applies radial pressure to the locking element, ensuring that the locking element is always locked in the snap-fit ​​groove of the roller brush shaft to form a stable connection. When disassembly is required, external force pulls the adjusting element to move axially to the unlocked position against the elastic force of the elastic element. The squeezing part and the locking element are misaligned to release the locking state. After the external force is removed, the elastic element immediately drives the adjusting element to reset to the locked position. This design realizes the self-locking function of the roller brush installation structure, which not only ensures the absolute reliability of the connection structure under working conditions, but also simplifies the operation process through the elastic reset mechanism. Users only need to apply force once to complete the unlocking, which is particularly suitable for working environments that require high-frequency maintenance.

[0012] In some embodiments, the elastic element is a compression spring that elastically abuts against the fixed cover and the adjusting element. The adjusting element has a limiting protrusion at one end facing the fixed cover, and the elastic element is at least partially sleeved on the limiting protrusion. This embodiment uses a compression spring as the elastic element, elastically abutting against the fixed cover and the adjusting element. The adjusting element has a limiting protrusion with a specific structure at one end facing the fixed cover, and the compression spring is at least partially sleeved on this limiting protrusion. This arrangement ensures that the compression spring maintains a stable axial movement trajectory during compression and rebound, preventing skewing. When the adjusting element moves to the unlocked position under external force, the limiting protrusion moves axially with the adjusting element and compresses the compression spring. At this time, the compression spring generates a reverse elastic force. Once the external force is removed, the compression spring immediately pushes the limiting protrusion to accurately reset the adjusting element to the locked position, ensuring that the pressing part and the locking part are realigned. This structural design not only improves the working reliability of the elastic element but also optimizes the stress state of the compression spring through the guiding effect of the limiting protrusion, extending the service life of the elastic element, while ensuring the accuracy and consistency of each locking action.

[0013] In some embodiments, a limiting hole is formed at the end of the plug-in cylinder facing away from the fixed cover. The adjusting member includes a first rod segment, a second rod segment, and a third rod segment connected sequentially along its own axial direction. The pressing part is protruding from the outer circumferential surface of the end of the first rod segment away from the second rod segment. The outer contour of the cross-section of the second rod segment is larger than the inner contour of the cross-section of the limiting hole. The third rod segment is telescopically inserted into the limiting hole. The adjusting member adopts a stepped structure in which the first rod segment, the second rod segment, and the third rod segment are connected sequentially. The outer side of the first rod segment is provided with a pressing part for locking the roller brush. The outer diameter of the second rod segment is larger than the inner diameter of the limiting hole at the end of the plug-in cylinder to form an axial limit. The third rod segment is slidably inserted into the limiting hole. When the adjusting member moves under the action of external force, the third rod segment extends and retracts axially along the limiting hole. When the second rod segment contacts the end face of the limiting hole, a hard limit is formed to prevent the adjusting member from excessive displacement or disengagement. This structural design ensures that the adjusting component can accurately return to the locked position under the drive of the elastic element, while the cooperation between the limiting hole and the rod segment prevents radial wobbling of the adjusting component during operation, ensuring that the squeezing part and the locking part always maintain a stable alignment. This solution is particularly suitable for high-intensity cleaning equipment that requires frequent disassembly and assembly of the roller brush, simplifying the operation process while improving the durability and reliability of the locking mechanism.

[0014] In some embodiments, the locking element is a ball bearing.

[0015] In some embodiments, the retaining cover is detachably connected to the insertion cylinder. The retaining cover can be fixed to the insertion cylinder via a detachable connection such as a threaded connection or a snap-fit. This design allows the retaining cover to be easily removed from the insertion cylinder, facilitating maintenance or replacement of internal elastic and adjusting components. When it is necessary to inspect or replace worn parts, only the retaining cover needs to be removed to directly access the internal mechanism, eliminating the need to replace the entire end cap assembly, significantly reducing maintenance costs.

[0016] In some embodiments, the end cap assembly further includes a bearing, the outer ring of which is fixed to the side cover, and the inner ring of which is fitted onto the outer circumferential surface of the connector cylinder. By placing a bearing between the side cover and the connector cylinder, with the outer ring fixed to the side cover and the inner ring fitted onto the outer circumferential surface of the connector cylinder, this arrangement ensures both the rotational flexibility of the connector cylinder and the stability of the axial support, allowing the connector cylinder to rotate smoothly relative to the side cover. This effectively reduces frictional resistance, lowers operating noise, and extends the service life of the equipment.

[0017] In some embodiments, the side cover has a mounting hole, the plug-in sleeve extends into the mounting hole, the outer ring of the bearing is fixed to the wall of the mounting hole, and the outer circumferential surface of the plug-in sleeve has a shielding flange located on the side of the bearing near the plug-in hole. The shielding flange, the outer circumferential surface of the plug-in sleeve, the wall of the mounting hole, and the end face of the roller brush shaft together form a receiving cavity for accommodating foreign objects. The plug-in sleeve has a shielding flange on its outer side, located on the side of the bearing near the plug-in hole. This shielding flange, together with the outer circumferential surface of the plug-in sleeve, the inner wall of the mounting hole, and the end face of the roller brush shaft, forms the receiving cavity. The receiving cavity can effectively collect foreign objects such as hair and fibers that seep in from the gap between the roller brush shaft and the side cover during operation, preventing them from affecting the normal rotation of the roller brush shaft and avoiding problems such as excessive friction causing the roller brush shaft to jam or excessive temperature causing the roller brush shaft to melt.

[0018] In some embodiments, the end cap assembly further includes a retaining ring fitted onto the outer circumferential surface of the insert sleeve, and the retaining ring abutting against the side of the bearing's inner ring facing away from the insert hole. This retaining ring, fitted onto the outer circumferential surface of the insert sleeve and abutting against the side of the bearing's inner ring facing away from the insert hole, forms a reliable axial constraint. This retaining ring fixing method effectively prevents axial movement of the bearing's inner ring during high-speed operation, ensuring a stable fit between the insert sleeve and the bearing.

[0019] In some embodiments, the end cap assembly further includes a sealing ring fitted onto the outer circumferential surface of the plug-in cylinder, the sealing ring sealingly abutting against the wall of the plug-in hole. This sealing ring can be a dynamic sealing ring, which can form an effective sealing structure between the plug-in hole and the plug-in cylinder to prevent the intrusion of external dust, liquids, and other contaminants.

[0020] In some embodiments, bristles are provided on the outer circumferential surface of the roller brush shaft.

[0021] This application also provides a cleaning device, which includes a device body, a drive shaft disposed on the device body, and a roller brush mounting structure as described in any of the above embodiments, wherein the device body is detachably connected to the side cover.

[0022] Because the aforementioned cleaning equipment includes the roller brush mounting structure described in any of the above embodiments, it also provides at least the following advantages: The roller brush mounting structure of this cleaning equipment achieves convenient locking and unlocking functions through the cooperation of the roller brush shaft and the end cap assembly. When the insertion sleeve of the end cap assembly is inserted into the insertion hole and connected to the roller brush shaft, the insertion sleeve and the roller brush shaft form a stable connection, ensuring that the roller brush shaft will not undergo relative displacement with the insertion sleeve during rotation. When disassembly is required, the insertion sleeve can be separated from the roller brush shaft and pulled out from the insertion hole. At this time, the insertion sleeve and the roller brush shaft are unlocked and can be easily separated. The entire process can be completed without the aid of tools, ensuring both the reliability of the connection during roller brush shaft rotation and the convenience of quick assembly and disassembly, making it particularly suitable for cleaning equipment requiring frequent cleaning and maintenance.

[0031] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0032] Please see Figure 1 In some embodiments, the present invention provides a roller brush mounting structure 10, which includes a roller brush shaft 100, an end cap assembly 200, and a locking mechanism.

[0033] One end of the roller brush shaft 100 is provided with a transmission hole 120, which is used for transmission connection with the drive shaft of the cleaning equipment. The other end of the roller brush shaft 100 is provided with a insertion hole 110. The end cap assembly 200 includes a side cover 210 and an insertion cylinder 220. The side cover 210 is disposed on the insertion hole 110 and is used for connection with the equipment body of the cleaning equipment. The insertion cylinder 220 is rotatably disposed on the side cover 210 and can be inserted into the insertion hole 110. A locking mechanism is provided on the insertion hole 110 and the insertion cylinder 220. The locking mechanism can fix or separate the roller brush shaft 100 from the insertion cylinder 220.

[0034] The roller brush mounting structure described above achieves at least the following beneficial effects: the roller brush shaft 100 and the end cap assembly 200 of this mounting structure are conveniently locked and unlocked through a locking mechanism. When the locking mechanism is locked, the insertion tube 220 is relatively fixed to the roller brush shaft 100 through the locking mechanism, forming a stable connection between the insertion tube 220 and the roller brush shaft 100, ensuring that the roller brush shaft 100 will not undergo relative displacement with the insertion tube 220 during rotation. When disassembly is required, the locking mechanism can be unlocked, and the insertion tube 220 can be separated from the roller brush shaft 100 and pulled out from the insertion hole 110. The entire process can be completed without the aid of tools, ensuring the reliability of the connection when the roller brush shaft 100 rotates, and achieving the convenience of quick assembly and disassembly.

[0035] Please continue to combine Figure 2 and Figure 3 In some embodiments, the locking mechanism includes a snap-fit ​​groove 111, a locking member 230, and an adjusting member 240. The snap-fit ​​groove 111 is recessed in the wall of the insertion hole 110, and a through hole 222 is formed in the wall of the insertion cylinder 220. The locking member 230 is movably disposed within the through hole 222. The adjusting member 240 is inserted into the insertion cylinder 220 and can move relative to the insertion cylinder 220 to a locked position and an unlocked position. In the locked position, the locking member 230, driven by the adjusting member 240, extends into the snap-fit ​​groove 111 to fix the brush shaft 100 relative to the insertion cylinder 220. In the unlocked position, the locking member 230 retracts from the snap-fit ​​groove 111 to separate the brush shaft 100 from the insertion cylinder 220. The roller brush mounting structure 10 achieves convenient locking and unlocking functions through the cooperation between the roller brush shaft 100 and the end cap assembly 200. The insertion hole 110 at one end of the roller brush shaft 100 is provided with a locking groove 111. When the insertion tube 220 of the end cap assembly 200 is inserted into the insertion hole 110, the movement of the adjusting member 240 in the insertion tube 220 can drive the locking member 230 to move radially in the through hole 222. When the adjusting member 240 moves to the locked position, it pushes the locking member 230 to extend outward and lock into the locking groove 111 of the roller brush shaft 100, so that the insertion tube 220 and the roller brush shaft 100 form a stable connection, ensuring that the roller brush shaft 100 will not have relative displacement with the insertion tube 220 when rotating. When disassembly is required, the adjusting member 240 moves to the unlocked position, causing a displacement change in the contact surface with the locking member 230. This causes the locking member 230 to lose its radial support and exit the locking groove 111. At this time, the insert cylinder 220 and the roller brush shaft 100 are unlocked and can be easily separated. The entire process can be completed without tools, ensuring the reliability of the connection when the roller brush shaft 100 rotates and achieving the convenience of quick assembly and disassembly. It is particularly suitable for cleaning equipment that requires frequent cleaning and maintenance.

[0036] It should be noted that, in addition to the locking engagement structure formed by the aforementioned snap-fit ​​groove 111, locking member 230, and adjusting member 240, the locking mechanism can also form a locking engagement structure in various other ways. For example, a recessed hole can be opened on the outer wall of the insertion tube 220, and a through hole corresponding to the position of the recessed hole can be opened on the hole wall of the insertion hole 110, and a movable locking tongue can be set in the through hole. The locking engagement structure is formed by the engagement of the locking tongue and the recessed hole. Alternatively, a magnet can be set on either the hole wall of the insertion hole 110 or the outer wall of the insertion tube 220, and a magnet with opposite magnetic poles can be set on the other. The locking engagement structure is formed by the principle of attraction between opposite magnetic poles.

[0037] like Figure 3 As shown, in some embodiments, the adjusting member 240 is rod-shaped and telescopically inserted into the insertion cylinder 220, and a pressing portion 2411 protrudes from the outer peripheral surface of the adjusting member 240. In the locked position, the locking member 230 can extend into the snap-fit ​​groove 111 under the pressing of the pressing portion 2411; in the unlocked position, the pressing portion 2411 is misaligned with the locking member 230 so that the locking member 230 can exit the snap-fit ​​groove 111. That is, the adjusting member 240 is axially telescopically inserted into the insertion cylinder 220 and its outer peripheral surface is provided with the pressing portion 2411. When the adjusting member 240 moves to the locked position, its pressing part 2411 aligns with the locking member 230; the pressing part 2411 applies radial pressing force to the locking member 230, forcing the locking member 230 to extend outward along the through hole 222 and embed into the snap-fit ​​groove 111 of the roller brush shaft 100. At this time, the insert cylinder 220 and the roller brush shaft 100 form a rigid connection. When the adjusting member 240 moves axially to the unlocked position, the pressing part 2411 and the locking member 230 are circumferentially misaligned; the locking member 230 loses the radial pressing force and, under the constraint of the inner wall of the insert cylinder 220, can retract to completely disengage from the snap-fit ​​groove 111, thereby unlocking the roller brush shaft 100 and the insert cylinder 220.

[0038] like Figure 3As shown, in some embodiments, the end cap assembly 200 further includes a fixing cap 250 and an elastic member 260. The elastic member 260 is disposed within the insertion cylinder 220, and the fixing cap 250 is disposed at one end of the insertion cylinder 220 for insertion into the insertion hole 110. One end of the elastic member 260 is connected to the fixing cap 250, and the other end of the elastic member 260 is connected to the adjusting member 240. The adjusting member 240 can move to the locked position under the elastic force of the elastic member 260, and the adjusting member 240 can also overcome the elastic force of the elastic member 260 under the action of external force to move to the unlocked position. By adding a fixing cap 250 and an elastic member 260 within the insertion cylinder 220, an elastic reset mechanism is formed, wherein the fixing cap 250 is disposed at the end of the insertion cylinder 220 inserted into the insertion hole 110 to form a limiting structure. The elastic element 260 is connected to the fixed cover 250 and the adjusting element 240 at both ends, so that the adjusting element 240 is automatically locked in the natural state by the elastic force of the elastic element 260. At this time, the squeezing part 2411 of the adjusting element 240 continuously applies radial pressure to the locking element 230, ensuring that the locking element 230 is always engaged in the snap-fit ​​groove 111 of the roller brush shaft 100 to form a stable connection. When disassembly is required, external force is applied to the adjusting element 240 to overcome the elastic force of the elastic element 260 and move it axially to the unlocked position. The squeezing part 2411 and the locking element 230 are misaligned and the locking state is released. After the external force is removed, the elastic element 260 immediately drives the adjusting element 240 to reset to the locked position. This design realizes the self-locking function of the roller brush mounting structure 10, which not only ensures the reliability of the connection structure in the working state, but also simplifies the operation process through the elastic reset mechanism. Users only need to apply force once to complete the unlocking, which is particularly suitable for working environments that require high-frequency maintenance.

[0039] like Figure 3As shown, in some embodiments, the elastic element 260 is a compression spring and elastically abuts against the fixed cover 250 and the adjusting element 240; the adjusting element 240 has a limiting protrusion 2412 protruding from one end facing the fixed cover 250, and the elastic element 260 is at least partially sleeved on the limiting protrusion 2412. This embodiment uses a compression spring as the elastic element 260 and elastically abuts against the fixed cover 250 and the adjusting element 240. The adjusting element 240 has a limiting protrusion 2412 with a specific structure at one end facing the fixed cover 250, and the compression spring is at least partially sleeved on this limiting protrusion 2412. This arrangement ensures that the compression spring maintains a stable axial movement trajectory during compression and rebound, avoiding deflection. When the adjusting member 240 moves to the unlocked position under the action of external force, the limiting protrusion 2412 moves axially with the adjusting member 240 and compresses the compression spring. At this time, the compression spring generates a reverse elastic force. Once the external force is removed, the compression spring immediately pushes the limiting protrusion 2412 to drive the adjusting member 240 to accurately reset to the locked position, ensuring that the pressing part 2411 and the locking member 230 are realigned. This structural design not only improves the working reliability of the elastic member 260, but also optimizes the stress state of the compression spring through the guiding effect of the limiting protrusion 2412, extends the service life of the elastic member 260, and ensures the accuracy and consistency of each locking action.

[0040] like Figure 3As shown, in some embodiments, the end of the insert cylinder 220 away from the fixed cover 250 has a limiting hole 221. The adjusting member 240 includes a first rod segment 241, a second rod segment 242, and a third rod segment 243 connected sequentially along its own axial direction. The first rod segment 241 has a protruding pressing part 2411 on its outer peripheral surface away from the second rod segment 242. The outer contour of the cross-section of the second rod segment 242 is larger than the inner contour of the cross-section of the limiting hole 221. The third rod segment 243 is telescopically inserted into the limiting hole 221. The adjusting member 240 adopts a stepped structure in which the first rod segment 241, the second rod segment 242, and the third rod segment 243 are connected sequentially. The first rod segment 241 has a pressing part 2411 for locking the roller brush on its outer side. The outer diameter of the second rod segment 242 is larger than the inner diameter of the limiting hole 221 at the end of the insert cylinder 220 to form an axial limit. The third rod segment 243 is slidably inserted into the limiting hole 221. When the adjusting member 240 moves under external force, the third rod segment 243 extends and retracts axially along the limiting hole 221. When the second rod segment 242 contacts the end face of the limiting hole 221, a hard limit is formed, preventing the adjusting member 240 from excessive displacement or disengagement. This structural design ensures that the adjusting member 240 can accurately return to the locked position under the drive of the elastic member 260, and also avoids radial swaying of the adjusting member 240 during operation through the cooperation of the limiting hole 221 and the rod segment, ensuring that the squeezing part 2411 and the locking member 230 always maintain a stable alignment relationship. This solution is particularly suitable for high-intensity cleaning equipment that requires frequent disassembly and assembly of the roller brush, simplifying the operation process while improving the durability and reliability of the locking mechanism.

[0041] like Figure 3 As shown, in some embodiments, the locking element 230 may be a ball bearing.

[0042] like Figure 3 As shown, in some embodiments, the fixing cover 250 is detachably connected to the insertion cylinder 220. The fixing cover 250 can be fixed to the insertion cylinder 220 by means of threaded connection, snap-fit, or other detachable connection methods. This design allows the fixing cover 250 to be easily removed from the insertion cylinder 220, facilitating maintenance or replacement of the internal elastic element 260 and adjusting element 240. When it is necessary to inspect or replace worn parts, only the fixing cover 250 needs to be removed to directly access the internal mechanism, without having to replace the entire end cover assembly 200, significantly reducing maintenance costs.

[0043] like Figure 3As shown, in some embodiments, the end cap assembly 200 further includes a bearing 270, the outer ring of which is fixed to the side cover 210, and the inner ring of which is sleeved on the outer circumferential surface of the insertion cylinder 220. By setting the bearing 270 between the side cover 210 and the insertion cylinder 220, with the outer ring of the bearing 270 fixed to the side cover 210 and the inner ring sleeved on the outer circumferential surface of the insertion cylinder 220, this arrangement ensures both the rotational flexibility of the insertion cylinder 220 and the stability of the axial support, allowing the insertion cylinder 220 to rotate smoothly relative to the side cover 210. This effectively reduces frictional resistance, lowers operating noise, and extends the service life of the equipment.

[0044] In some embodiments, the insertion hole 110 can be in various shapes, such as Figure 5 The cross-section shown has a D-shaped or other irregular hole. The insertion cylinder 220 is adapted to the insertion hole 110 so that the insertion cylinder 220 can rotate under the drive of the roller brush shaft 100.

[0045] Please see Figure 3 and combined Figure 1 In some embodiments, the side cover 210 has a mounting hole 211, the plug-in sleeve 220 extends into the mounting hole 211, the outer ring of the bearing 270 is fixed to the wall of the mounting hole 211, and the outer circumferential surface of the plug-in sleeve 220 has a shielding flange 223. The shielding flange 223 is located on the side of the bearing 270 near the plug-in hole 110. The shielding flange 223, the outer circumferential surface of the plug-in sleeve 220, the wall of the mounting hole 211, and the end face of the roller brush shaft 100 together form a receiving cavity 212 for accommodating foreign objects. The adjusting member 240 has a shielding flange 223 on its outer side. The shielding flange 223 is located on the side of the bearing 270 near the plug-in hole 110. The shielding flange 223, the outer circumferential surface of the plug-in sleeve 220, the inner wall of the mounting hole 211, and the end face of the roller brush shaft 100 together form the receiving cavity 212. The receiving cavity 212 can effectively collect foreign objects such as hair and fibers that have entered through the gap between the roller brush shaft 100 and the side cover 210 during operation, preventing them from affecting the normal rotation of the roller brush shaft 100 and avoiding problems such as excessive friction causing the roller brush shaft 100 to jam or excessive temperature causing the roller brush shaft 100 to melt and deform.

[0046] like Figure 3As shown, in some embodiments, the end cap assembly 200 further includes a retaining ring 280, which is sleeved on the outer peripheral surface of the insertion sleeve 220 and abuts against the side of the inner ring of the bearing 270 facing away from the insertion hole 110. The retaining ring 280, sleeved on the outer peripheral surface of the insertion sleeve 220 and abutting against the side of the inner ring of the bearing 270 facing away from the insertion hole 110, forms a reliable axial constraint. This retaining ring 280 fixing method effectively prevents axial movement of the inner ring of the bearing 270 during high-speed operation, ensuring a stable fit between the insertion sleeve 220 and the bearing 270.

[0047] like Figure 3 As shown, in some embodiments, the end cap assembly 200 further includes a sealing ring 290 fitted onto the outer peripheral surface of the insertion cylinder 220, the sealing ring 290 sealingly abutting against the wall of the insertion hole 110. This sealing ring 290 can be a dynamic sealing ring 290, which can form an effective sealing structure between the insertion hole 110 and the insertion cylinder 220 to prevent the intrusion of external dust, liquids, and other contaminants.

[0048] like Figure 4 As shown, in some embodiments, the outer peripheral surface of the roller brush shaft 100 is provided with bristles 130.

[0049] In addition, this application also provides a cleaning device, which includes a device body, a drive shaft disposed on the device body, and a roller brush mounting structure 10 as described in any of the above embodiments, wherein the device body is detachably connected to the side cover 210.

[0050] Since the above-described cleaning equipment includes the roller brush mounting structure 10 as described in any of the above embodiments, the cleaning equipment also has at least the following beneficial effects: the roller brush mounting structure 10 of the cleaning equipment achieves convenient locking and unlocking through a locking mechanism between the roller brush shaft 100 and the end cap assembly 200. When the locking mechanism is locked, the insertion sleeve 220 of the end cap 200 can be relatively fixed to the roller brush shaft 100 through the locking mechanism, and the insertion sleeve 220 and the roller brush shaft 100 form a stable connection, ensuring that the roller brush shaft 100 will not have relative displacement with the insertion sleeve 220 when rotating. When disassembly is required, the locking mechanism can be unlocked, and the insertion sleeve 220 can be separated from the roller brush shaft 100 and pulled out from the insertion hole 110. The entire process can be completed without the aid of tools, which not only ensures the reliability of the connection when the roller brush shaft 100 rotates, but also achieves the convenience of quick disassembly and assembly, making it particularly suitable for cleaning equipment that requires frequent cleaning and maintenance.
