[0096] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0097] The following is combined Figures 1-20 This describes an embodiment of the roller disassembly and assembly structure and cleaning equipment of the present invention.

[0098] According to an embodiment of the present invention, in a first aspect, a roller disassembly and assembly structure is provided for use in a cleaning device. The cleaning device includes a roller assembly 2, which includes a second support 201 and a roller 202. The roller 202 is detachably disposed within the second support 201. The roller disassembly and assembly structure includes a cover 6, a locking component, and a pop-out component. The cover 6 is disposed at one end of the roller 202. The locking component is disposed within the second support 201 and is used to lock / unlock the cover 6 to disassemble and assemble the roller 202. The pop-out component is disposed at the other end of the roller 202 and pops the roller 202 out of the second support 201 when the locking component unlocks the cover 6.

[0099] This roller assembly / disassembly structure includes a locking component and a pop-out component. The locking component is used to lock / unlock the cover 6 to assemble / disassemble the roller 202, and when the locking component unlocks the cover 6, the pop-out component can pop the roller 202 out of the second bracket 201. Through the locking component and the pop-out component, the roller 202 can be easily assembled / disassembled, the operation is simple, it is convenient for users to replace the roller 202, and the user experience is good. Moreover, the locking component and the pop-out component are respectively set at both ends of the roller 202, occupying little space, which is conducive to the compact design of the whole machine. It can make the side structure of the roller 202 thinner, thereby reducing the distance between the roller 202 and the wall and improving the cleaning effect.

[0100] The roller assembly / disassembly structure is used in cleaning equipment, such as single-roller or double-roller sweepers, single-roller or double-roller handheld floor scrubbers, floor cleaning robots, and other cleaning equipment. The cleaning equipment includes a roller assembly 2, which includes a second bracket 201 and a roller 202. The roller 202 is detachably mounted in the second bracket 201, and the roller 202 can be easily disassembled and replaced through the roller assembly / disassembly structure.

[0101] Specifically, the roller assembly 2 has a generally elongated strip-shaped structure. The second support 201, also known as a telescopic support, is the shell structure of the roller assembly 2. The second support 201 has a certain structural strength and can support and mount the roller 202, etc. In addition, the first support 1 can also be equipped with structural components such as a dirt collection tank and a water channel plate. The roller 202 is housed within the second support 201 and is the roller mop. In this embodiment, the roller structure is a double-roller structure, meaning there are two rollers 202. The rollers 202 are located on the side of the second support 201 facing the surface to be cleaned. When the cleaning equipment is working, the rollers 202 can rotate and roll to clean the surface. The roller assembly / disassembly structure of this embodiment can be applied to cleaning equipment such as sweepers, mops, floor scrubbers, or cleaning robots. Depending on the application scenario of different cleaning equipment, the surface to be cleaned can be a floor, a wall, etc. In this embodiment, the surface to be cleaned is a floor.

[0102] The roller assembly / disassembly structure includes a cover 6, a locking component, and a pop-out component. The cover 6 is located at one end of the roller 202. The cover 6 is used to seal one end of the roller 202 to make the overall appearance more aesthetically pleasing and neat, and to prevent dust, debris, etc. from entering the inside of the roller 202, affecting the operation and service life of the roller 202.

[0103] A locking component is disposed within the second bracket 201. This component is used to lock / unlock the cover 6 to assemble and disassemble the roller 202. The locking component secures the cover 6 to the second bracket 201. Since the cover 6 is fixed to one end of the roller 202, the roller 202 is locked to the second bracket 201, thus enabling the installation of the roller 202. Figure 1 As shown; and the locking component can unlock the cover 6 from the second bracket 201. Since the cover 6 is fixed to one end of the roller 202, the roller 202 is unlocked from the second bracket 201, thus realizing the disassembly of the roller 202, as shown. Figure 2 As shown.

[0104] The pop-out component is located at the other end of the roller 202. When the locking component unlocks the cover 6, the pop-out component pushes the roller 202 out of the second bracket 201, making it convenient for the user to take the roller 202 out and replace it. Figure 2 As shown. Moreover, since the locking component and the pop-out component are respectively located at both ends of the roller 202, they do not affect or interfere with each other, making the distance between both ends of the roller 202 and the wall relatively small. This allows the roller 202 to clean as close to the edge as possible, reducing dust accumulation in corners and other edge areas, thereby improving the overall cleaning effect and providing a better user experience.

[0105] Furthermore, at least two rollers 202 are provided, and each roller 202 has a cover 6 at one end. The locking component locks / unlocks all covers 6 simultaneously.

[0106] The number of rollers 202 on the cleaning equipment can be more than one, such as two or three. Each roller 202 has a cover 6 at one end. The locking component in this embodiment can lock / unlock all covers 6 at the same time, so as to disassemble and install all rollers 202 at the same time, improve the replacement efficiency of rollers 202, and simplify user operation.

[0107] In this embodiment, two rollers 202 are provided, and the two rollers 202 are arranged side by side on the second bracket 201. The ends of the two rollers 202 on the same side are provided with covers 6. The locking component is provided inside the second bracket 201 and placed between the two rollers 202 so that the locking component can lock / unlock the two covers 6 at the same time.

[0108] Furthermore, the locking assembly includes a third bracket 7, a button 9, and at least one locking member 14. The third bracket 7 is disposed on the second bracket 201, the button 9 and the locking member 14 are disposed on the third bracket 7, the locking member 14 has a locked position for locking the cover 6 and an unlocked position for unlocking the cover 6, the button 9 is connected to the locking member 14 and switches the locking member 14 between the locked position and the unlocked position.

[0109] like Figure 3 As shown, the third bracket 7 serves as the support for the locking assembly, with components such as the button 9 and the locking element 14 mounted on it. The third bracket 7 is positioned within the second bracket 201, with most of its structure located inside. The button 9 is movably mounted on the third bracket 7, with its operating surface positioned on the outer side for easy user operation. In this embodiment, the button 9 moves along a straight line. The third bracket 7, equipped with the button 9 and at least one locking element 14, forms a modular structure, facilitating assembly and improving assembly efficiency.

[0110] The locking element 14 is located inside the third bracket 7. The locking element 14 has a locked position for locking the cover 6 and an unlocked position for unlocking the cover 6. The button 9 is connected to the locking element 14 to control its movement. Under the control of the button 9, the locking element 14 switches between the locked and unlocked positions. When the locking element 14 is in the locked position, it locks the cover 6, and the roller 202 is installed in place. When the locking element 14 is in the unlocked position, the cover 6 is unlocked, and the roller 202, under the action of the pop-out component, pops out the second bracket 201 for easy replacement by the user.

[0111] Furthermore, the locking member 14 is rotatably disposed within the third bracket 7, and the locking assembly also includes a first elastic member 15. The first elastic member 15 is sleeved on the pivot 16 of the locking member 14. One end of the first elastic member 15 abuts against the third bracket 7, and the other end abuts against the locking member 14. The first elastic member 15 applies a force to the locking member 14 to rotate toward the locked position.

[0112] like Figures 4-11 As shown, the locking member 14 is rotatably disposed within the third bracket 7. In this embodiment, the locking member 14 is rotatably disposed within the third bracket 7 around the rotating shaft 16, which is disposed vertically within the third bracket 7. The locking member 14 can rotate around the rotating shaft 16 under the control of the button 9 to switch between the locked position and the unlocked position.

[0113] The first elastic element 15 is sleeved on the rotating shaft 16. The first elastic element 15 is a torsion spring. One end of the first elastic element 15 abuts against the third bracket 7, and the other end abuts against the locking element 14. The first elastic element 15 can apply a force to the locking element 14 to make it rotate toward the locked position.

[0114] Specifically, a pivot 16 is sleeved in the middle of the locking member 14. The locking member 14 has two opposite ends, namely a first end and a second end. The first end is a hook 1401 for locking / unlocking the cover 6. The second end abuts against the button 9. Correspondingly, the cover 6 has a groove 601 that engages with the hook 1401.

[0115] When the user presses button 9 inward (e.g.) Figure 7 (As shown by the arrow x direction), button 9 overcomes the torque of the first elastic element 15, pushing the locking element 14 to rotate around the pivot 16, causing the hook 1401 to disengage from the groove 601, and the cover 6 to unlock; when the user releases button 9, under the action of the elastic restoring force of the first elastic element 15, button 9 moves outward (as shown by the arrow x direction). Figure 7 (As shown by arrow x' direction), the locking part 14 returns to the locked position, and the hook 1401 engages with the groove 601 to lock the cover 6. However, if a new roller 202 is not installed at this time, the hook 1401 will not engage with the groove 601.

[0116] Furthermore, the locking assembly also includes a locking member guide mechanism, which is disposed between the locking member 14 and the third bracket 7, and is used to limit the rotation trajectory of the locking member 14.

[0117] The locking assembly also includes a locking member guide mechanism, which is used to limit the rotation trajectory of the locking member 14, improve the reliability of the rotation of the locking member 14, prevent the locking member 14 from falling out of the installation position, and also assist in the installation of the locking member 14 during the assembly of the locking assembly, thereby improving the assembly efficiency.

[0118] In this embodiment, the second end of the locking member 14 is disposed opposite to the hook 1401, and the locking member guide mechanism is disposed at the second end of the locking member 14, the rotation trajectory of the second end being arc-shaped.

[0119] Furthermore, the locking member guiding mechanism includes a slidingly fitted guide post 1701 and a guide groove 1702, one of which is disposed on the locking member 14, and the other is disposed on the third bracket 7.

[0120] In this embodiment, a guide post 1701 is disposed on the locking member 14, and a guide groove 1702 is disposed on the third bracket 7. The guide post 1701 is disposed at the second end of the locking member 14, and the guide post 1701 is arranged vertically. The guide groove 1702 is formed on the bottom surface of the third bracket 7, and the lower end of the guide post 1701 is slidably placed in the guide groove 1702. The extending direction of the guide groove 1702 matches the rotation trajectory of the locking member 14.

[0121] In other embodiments, the guide post 1701 can also be provided on the third bracket 7, and the guide groove 1702 can be provided on the locking member 14, as long as the rotation trajectory of the locking member 14 can be limited, so as to improve the reliability of the mechanism.

[0122] Furthermore, there are two locking elements 14, which are symmetrically arranged relative to the moving direction of the button 9.

[0123] In this embodiment, two rollers 202 are provided. Correspondingly, the roller disassembly and assembly structure includes two covers 6, with one cover 6 provided at one end of each roller 202. A third bracket 7 is placed between the two rollers 202. Two locking members 14 are provided, each used to lock / unlock one cover 6, so that one button 9 can simultaneously install and disassemble two rollers 202. The movement direction of button 9 is as follows: Figure 7 As shown by the middle arrow x-x', the two locking parts 14 are symmetrically arranged relative to the moving direction of the button 9 to facilitate structural design, making the structure compact and reducing the volume.

[0124] Furthermore, the locking assembly also includes a button guide mechanism, which is disposed between the button 9 and the third bracket 7, and is used to limit the movement trajectory of the button 9.

[0125] The locking assembly also includes a button guide mechanism, which is used to limit the movement trajectory of button 9, so that button 9 can move in its movement direction, prevent button 9 from shifting position after long-term use, and improve the reliability of the structure.

[0126] In this embodiment, the button guiding mechanism includes a slidingly engaged guide rib 1801 and a guide hole 1802, one of which is disposed on the button 9 and the other is disposed on the third bracket 7.

[0127] Specifically, guide rib 1801 is located at the bottom of the third bracket 7, and guide hole 1802 is located at the button 9. Guide rib 1801 can be inserted into guide hole 1802 to limit the movement trajectory of button 9. The extension direction of guide rib 1801 is the direction of arrow x-x'. This button guiding mechanism does not occupy too much space, which helps to improve the reliability of the structure and allows for a compact structural design.

[0128] In other embodiments, the guide rib 1801 may also be provided on the button 9, and the guide hole 1802 may be provided on the third bracket 7.

[0129] Furthermore, the locking assembly also includes a button limiting mechanism, which is disposed on the button 9 and the third bracket 7, and is used to prevent the button 9 from dislodging from the third bracket 7.

[0130] When the user releases button 9, button 9 will move outward under the elastic restoring force of the first elastic element 15 (arrow x' direction). In order to prevent button 9 from falling out of the third bracket 7, a button limiting mechanism is provided to improve the reliability of the structure.

[0131] In this embodiment, the button limiting mechanism includes a limiting buckle 23, which is disposed on the button 9 and protrudes from the surface of the button 9. Correspondingly, a limiting groove is provided on the third bracket 7, and the limiting buckle 23 can engage with the limiting groove to limit the button 9. Specifically, the limiting buckle 23 is disposed on the top surface of the button 9 to avoid interference with other structural components.

[0132] Furthermore, the roller assembly / disassembly structure also includes a rotation limiting component, which is disposed between the cover 6 and the roller 202. The rotation limiting component is used to prevent the cover 6 from rotating with the roller 202.

[0133] When the cover 6 is connected to one end of the roller 202, the cover 6 will not rotate with the roller 202 to avoid affecting the cleaning work of the roller 202, and at the same time, it can provide reliable protection for the roller 202.

[0134] The rotation limiting assembly is used to prevent the cover 6 from rotating with the roller 202. Specifically, the rotation limiting assembly includes a first mounting member 19 and a bearing 20. The first mounting member 19 is fixed to the roller 202, and one of the inner ring and the outer ring of the bearing 20 is fixed to the first mounting member 19, while the other is fixed to the cover 6.

[0135] In this embodiment, the first mounting member 19 is fixed to one end of the roller 202 and the cover 6. The inner ring of the bearing 20 is fixed to the first mounting member 19, and the outer ring of the bearing 20 is fixed to the cover 6, so that the first mounting member 19 can rotate with the roller 202, while the cover 6 will not rotate with the roller 202.

[0136] In other embodiments, the outer ring of the bearing 20 may be fixed to the first mounting member 19, and the inner ring may be fixed to the cover 6.

[0137] To facilitate structural installation, the rotation limiting assembly also includes a fixed shaft 21, through which one of the inner and outer rings of the bearing 20 is fixed to the first mounting member 19. In this embodiment, the first mounting member 19 is connected and fixed to the fixed shaft 21, and the fixed shaft 21 is also fixed to the inner ring of the bearing 20, thereby facilitating the connection and setup of the structure.

[0138] To improve connection reliability, the fixed shaft 21 is interference-fitted with the first mounting part 19, the fixed shaft 21 is interference-fitted with the inner ring of the bearing 20, and the outer ring of the bearing 20 is interference-fitted with the cover 6. Simultaneously, the cover 6 is also engaged with the outer ring of the bearing to prevent the cover 6 from detaching axially.

[0139] Furthermore, the roller assembly / disassembly structure also includes a cover circumferential limiting mechanism, which is located between the cover 6 and the second support 201. The cover circumferential limiting mechanism is used to prevent the cover 6 from rotating circumferentially relative to the second support 201.

[0140] To prevent the cover 6 from rotating circumferentially relative to the second support 201, a circumferential limiting mechanism for the cover is provided between the cover 6 and the second support 201, thereby improving the reliability of the structure and the assembly efficiency of the cover 6.

[0141] In this embodiment, the circumferential limiting mechanism of the cover includes a limiting protrusion 11, which is disposed on the inner side of the cover 6. A limiting groove is provided at the corresponding position of the second bracket 201. The limiting protrusion 11 can be inserted into the limiting groove so that the cover 6 will not rotate circumferentially relative to the second bracket 201, thereby improving the reliability of the structure.

[0142] In addition, a circumferential mounting groove is provided on the inner side of the cover 6. The edge of the first mounting member 19 facing the cover 6 is suitable for insertion into the mounting groove to achieve installation and improve the reliability of assembly. A limiting protrusion 11 is provided at the circumferential mounting groove to restrict the circumferential rotation of the cover 6.

[0143] Further, the pop-out component includes a first housing 2201, a second housing 2202, and a second elastic member 2203. The second elastic member 2203 is disposed between the first housing 2201 and the second housing 2202, with one end of the second elastic member 2203 abutting against the first housing 2201 and the other end abutting against the second housing 2202. The end of the first housing 2201 away from the second housing 2202 abuts against or separates from the roller 202. When the locking member 14 of the locking component switches from the unlocked position to the locked position, the end of the first housing 2201 away from the second housing 2202 abuts against the roller 202, and the first housing 2201 moves toward the second housing 2202, compressing the second elastic member 2203. When the locking member 14 switches from the locked position to the unlocked position, the second elastic member 2203 resets, and the first housing 2201 moves away from the second housing 2202, with the end of the first housing 2201 away from the second housing 2202 pushing out of the roller 202.

[0144] like Figure 12 As shown, the pop-out component is located at the other end of the roller 202. The output shaft 501 of the rotation drive 5 at this end is connected to the roller 202 for transmission, thereby driving the roller 202 to rotate.

[0145] The pop-out assembly includes a first housing 2201, a second housing 2202, and a second elastic member 2203. The first housing 2201 and the second housing 2202 are sleeved on the output shaft 501 of the rotation drive member 5. The first housing 2201 and the second housing 2202 are fastened together, and the first housing 2201 can move towards / away from the second housing 2202, but the first housing 2201 cannot detach from the second housing 2202. The second housing 2202 is fixed to the output shaft 501 by a fixing pin 13. Specifically, the edge of the first housing 2201 facing the second housing 2202 and the edge of the second housing 2202 facing the first housing 2201 are connected by a snap-fit ​​structure. The snap-fit ​​mechanism is used to prevent the first housing 2201 from disengaging from the second housing 2202 when the locking member 14 switches from the locked position to the unlocked position. This allows the first housing 2201 to move towards or away from the second housing 2202, but the first housing 2201 cannot disengage from the second housing 2202 along the axial direction of the output shaft 501. The second elastic member 2203 is specifically a spring.

[0146] The second elastic element 2203 is disposed between the first housing 2201 and the second housing 2202, with one end of the second elastic element 2203 abutting against the first housing 2201 and the other end abutting against the second housing 2202. Specifically, the second housing 2202 has a mounting post at its internal center, and the second elastic element 2203 is sleeved on the mounting post so that the second elastic element 2203 can be centrally positioned, making the elastic force stable and facilitating the balanced force on the roller 202. When the roller 202 is installed, the first housing 2201 moves towards the second housing 2202, and the second elastic element 2203 is compressed. When the roller 202 is disassembled, under the elastic restoring force of the second elastic element 2203, the first housing 2201 is ejected and moves away from the second housing 2202. The first housing 2201 drives the roller 202 to pop out of the second bracket 201, making it easy for the user to remove and replace.

[0147] The end of the first housing 2201 away from the second housing 2202 abuts against or separates from the roller 202. In this embodiment, the output shaft 501 is also provided with a sleeve 12 and a second mounting member 24. The sleeve 12 and the second mounting member 24 are fixed to the roller 202. The sleeve 12 and the second mounting member 24 can rotate with the roller 202, and the sleeve 12 and the second mounting member 24 can reciprocate along the axial direction of the output shaft 501 with the roller 202. The end of the first housing 2201 away from the second housing 2202 abuts against or separates from the sleeve 12 to eject the roller 202.

[0148] A limit pin 25 is provided at the end of the output shaft 501 to prevent the sleeve 12 from dislodging from the output shaft 501, which would cause the roller 202 to be ejected too far. A structure, such as a through hole, is provided on the second mounting member 24 that can pass over the limit pin 25. Furthermore, an interference fit structure, such as an interference fit sealing ring, exists between the sleeve 12 and the second mounting member 24. Under the action of the ejection assembly, the sleeve 12, the second mounting member 24, and the roller 202 are ejected. At this point, the user needs to forcefully pull out the roller 202 to disengage the second mounting member 24 from the sleeve 12, thereby removing the roller 202.

[0149] This embodiment also provides a cleaning device, including a roller assembly 2 and a roller disassembly and assembly structure as described above, wherein the roller 202 of the roller assembly 2 is disassembled and assembled through the roller disassembly and assembly structure.

[0150] The roller assembly 2 of the cleaning equipment is disassembled and assembled using the roller disassembly and assembly structure of this embodiment. The operation is simple and the disassembly and assembly efficiency is high. The roller disassembly and assembly structure is simple in structure and occupies a small volume, making the side of the roller assembly 2 very thin, which can reduce the distance between the roller and the wall and improve the cleaning effect.

[0151] like Figures 19-20As shown, the cleaning device also includes a first support 1 and a telescopic drive assembly, which includes a first control assembly and a second control assembly. The roller assembly 2 is telescopically and movably disposed at the bottom of the first support 1.

[0152] Under the drive control of the telescopic drive component, the roller assembly 2 can telescopically move. When cleaning corner areas such as walls, the force exerted by the second control component on the roller assembly 2 is less than that exerted by the first control component. The first control component drives the roller assembly 2 to extend relative to the first support 1, allowing the roller assembly 2 to be closer to the corner area without being affected by the position of the first support 1, achieving "edge cleaning" to effectively clean corner areas, significantly reducing blind spots and greatly improving cleaning effect. When corner areas do not need to be cleaned (i.e., when the roller assembly 2 needs to return to its original position), the force exerted by the second control component on the roller assembly 2 is greater than that exerted by the first control component, causing the roller assembly 2 to retract relative to the first support 1. Through the coordinated operation of the first and second control components, the position of the roller assembly 2 can be adjusted, making the roller assembly 2 more controllable and its telescopic movement smoother. This roller assembly structure not only provides better cleaning effect but also enhances the user experience.

[0153] The first support 1 possesses sufficient structural strength to support and mount the roller assembly 2 and the telescopic drive assembly. Typically, the first support 1 is made of waterproof, corrosion-resistant, and high-strength materials to ensure the overall service life of the roller structure. The first support 1 has a generally elongated, strip-like structure. Figure 19 and Figure 20 Taking the perspective of the first bracket 1 as an example, the bottom of the first bracket 1 faces the surface to be cleaned.

[0154] The roller assembly 2 is telescopically and movably mounted on the first support 1. The roller assembly 2 is primarily used for cleaning the surface to be cleaned. During operation, the roller assembly 2 directly contacts the surface to be cleaned, thus completing the cleaning process. The roller assembly 2 is located at the bottom of the first support 1 and can telescopically move relative to the first support 1; that is, the position of the roller assembly 2 relative to the first support 1 is not fixed and can change. The roller assembly 2 can extend relative to the first support 1. When the roller assembly 2 extends to a preset extended position (fully extended), it is in the extended state. Correspondingly, the roller assembly 2 can retract relative to the first support 1. When the roller assembly 2 retracts to a preset retracted position (fully retracted), it is in the retracted state. In other words, the roller assembly 2 can reciprocate between the corresponding positions of the extended and retracted states; that is, the roller assembly 2 can move from the retracted position to the extended position, and vice versa.

[0155] The second support 201 is also provided with a first connector 204, through which the first control component is connected to the roller assembly 2. Furthermore, the second support 201 is also provided with a second connector 203, through which the second control component is connected to the roller assembly 2. Of course, the roller assembly 2 also has other structures and components common to existing roller assemblies, which will not be elaborated here.

[0156] In this embodiment, the first connector 204 and the second connector 203 are located on both sides of the roller assembly 2, so that the structure on the roller assembly 2 is more balanced and the structure is not too concentrated. When the first control component and the second control component apply force to the roller assembly 2, the extension and retraction movement of the roller assembly 2 can be more stable.

[0157] A telescopic drive assembly is mounted on the first support 1 and is used to control the telescopic movement of the roller assembly 2. The telescopic drive assembly includes a first control assembly and a second control assembly, both of which can apply force to the roller assembly 2 to achieve its telescopic movement. When the force exerted by the second control assembly on the roller assembly 2 is less than the force exerted by the first control assembly, the first control assembly causes the roller assembly 2 to extend relative to the first support 1. When the force exerted by the second control assembly on the roller assembly 2 is greater than the force exerted by the first control assembly, the second control assembly causes the roller assembly 2 to retract relative to the first support 1.

[0158] In other words, by adjusting the force exerted on the roller assembly 2 by the first control component and the second control component, the roller assembly 2 can be moved to the extended position under the control of the first control component, and the roller assembly 2 can also be moved to the retracted position under the control of the second control component.

[0159] Specifically, the roller assembly 2 is telescopically and movably disposed on the side of the first bracket 1 facing the surface to be cleaned. The first control component drives the roller assembly 2 to extend out of the projection range of the first bracket 1 on the surface to be cleaned, and the second control component drives the roller assembly 2 to retract into the projection range of the first bracket 1 on the surface to be cleaned.

[0160] In this embodiment, the bottom of the first support 1 faces the surface to be cleaned, and the roller assembly 2 is telescopically and movably disposed at the bottom of the first support 1. The surface to be cleaned is the ground. In the retracted state, the entire roller assembly 2 is within the projection range of the first support 1 on the ground. The first control component can drive the roller assembly 2 to extend beyond this projection range, and the second control component can drive the roller assembly 2 to retract into this projection range. That is, when the roller assembly 2 is in the retracted state, it is not visible from the top view of the first support 1. When the roller assembly 2 is in the extended state, at least a portion of its structure is outside the first support 1. This roller structure is suitable for cleaning equipment such as sweepers, which simplifies structural design, reduces control difficulty, and facilitates maintenance, replacement, and storage. In this embodiment, when the roller assembly 2 is in the retracted state, the outer edge of the roller assembly 2 is flush with the outer edge of the first support 1.

[0161] Both the first control component and the second control component are located on the first support 1, but the first control component is located above one of the rollers 202, while the second control component is located above the other roller 202.

[0162] When the first control component and the second control component apply force to the first support 1, the direction of the force applied by the first control component to the roller assembly 2 is parallel to and does not coincide with the direction of the force applied by the second control component to the roller assembly 2. This achieves the distributed setting of the first control component and the second control component, making full use of the setting space on the first support 1, and making the roller assembly 2 more evenly stressed. This is beneficial to the stable driving of the telescopic drive component to the roller assembly 2, and makes the telescopic movement of the roller assembly 2 smoother.

[0163] Specifically, the second support 201 is provided with a first connector 204 and a second connector 203. The force-applying end of the first control component is connected to the first connector 204, and the force-applying end of the second control component is connected to the second connector 203. The first connector 204 and the second connector 203 are respectively located on both sides of the roller assembly 2, that is, the first connector 204 and the second connector 203 are respectively located above the two rollers 202, so that the structural arrangement on the roller assembly 2 is more balanced. When the first control component and the second control component apply force to the roller assembly 2, the extension and retraction movement of the roller assembly 2 can be more balanced and stable.

[0164] The first control component includes a control element 8, which is disposed on the first support 1. The control element 8 applies a pulling force to the roller assembly 2 in the extension direction of the roller assembly 2.

[0165] In this embodiment, the first control component includes a control element 8, which applies a pulling force to the roller assembly 2 in the extension direction. The control element 8 is disposed on the first bracket 1 and has a force-applying end connected to the roller assembly 2. The control element 8 applies a pulling force to the roller assembly 2 through the force-applying end. Specifically, the force-applying end of the control element 8 is connected to the first connecting member 204.

[0166] The second control component includes a telescopic drive component 3 and a traction component 4. The telescopic drive component 3 is disposed on the first support 1. One end of the traction component 4 is driven by the telescopic drive component 3, and the other end of the traction component 4 is connected to the roller assembly 2. The telescopic drive component 3 is specifically a drive motor.

[0167] Specifically, the pulling member 4 is U-shaped and mounted on the first support 1 to fully utilize the space on the first support 1. The pulling member 4 is made of steel wire rope, wound around a winding reel. One end of the pulling member 4 is connected to the output end of the telescopic drive member 3, and the other end is connected to the second connecting member 203. The telescopic drive member 3 provides power so that the second control component can apply force to the roller assembly 2. One end of the pulling member 4 is driven by the telescopic drive member 3, and the other end of the pulling member 4 is connected to the roller assembly 2 via the second connecting member 203. The pulling member 4 is used to pull the roller assembly 2 and, by overcoming the force exerted on the roller assembly 2 by the first control component, drives the roller assembly 2 to retract relative to the first support 1.

[0168] In this embodiment, the control element 8 is an elastic element. When the roller assembly retracts relative to the first support 1, the control element 8 is in a stretched state.

[0169] Figure 19 The middle arrow 'a' indicates the direction of extension. Figure 20 The middle arrow b indicates the retraction direction. In this embodiment, the control element 8 is an elastic element. When the roller assembly 2 retracts relative to the first support 1, the control element 8 is in a stretched state. Specifically, the control element 8 is a tension spring. When the telescopic drive element 3 is not working, the roller assembly 2 will remain in its normally extended state under the force of the tension spring.

[0170] One end of the control element 8 is connected to the first support 1, and the other end is connected to the roller assembly 2 via the first connector 204. When the roller assembly 2 retracts relative to the first support 1, the control element 8 is in a stretched state, and the control element 8 can apply a pulling force to the roller assembly 2 in the extension direction. When the pulling member 4 is released, under the pulling force of the control element 8, the roller assembly 2 extends relative to the first support 1 until it reaches the preset extension position. The tension force of the tension spring on the roller assembly 2 varies. When the roller assembly 2 moves toward the preset retracted position, the tension force of the tension spring on the roller assembly 2 gradually increases, while when the roller assembly 2 moves toward the preset extension position, the tension force of the tension spring on the roller assembly 2 gradually decreases, but it is necessary to keep the roller assembly 2 in the preset extension position.

[0171] The telescopic drive assembly also includes a telescopic positioning detection element 1001 and a telescopic positioning detection column 1002. When the telescopic positioning detection column 1002 contacts the telescopic positioning detection element 1001, the roller assembly 2 retracts into position to increase the reliability of the mechanism.

[0172] To make the telescopic movement of the roller assembly 2 more stable and reliable, a guide rail mechanism is provided between the first support 1 and the second support 201. The extension direction of the guide rail mechanism is consistent with the telescopic direction of the roller assembly 2. The guide rail mechanism is set between the first support 1 and the second support 201, which can save the installation space, make the overall structure more compact and reasonable, and at the same time make the roller assembly 2 telescopic movement more stable relative to the first support 1.

[0173] When cleaning corner areas such as walls, the force exerted by the second control component on the roller assembly 2 is less than that exerted by the first control component. The first control component causes the roller assembly 2 to extend relative to the first support 1, allowing it to be closer to the corner area without being affected by the position of the first support 1, achieving "edge cleaning." This effectively cleans corner areas, significantly reducing blind spots and greatly improving cleaning performance. When corner cleaning is no longer needed (i.e., when the roller assembly 2 needs to return to its original position), the force exerted by the second control component on the roller assembly 2 is greater than that exerted by the first control component, causing the roller assembly 2 to retract relative to the first support 1. Through the coordinated operation of the first and second control components, the position of the roller assembly 2 can be adjusted, making it more controllable and its extension and retraction smoother. This roller structure not only provides better cleaning results but also enhances the user experience.

[0174] Of course, cleaning equipment also has other structural components that are present in all existing cleaning equipment, which will not be elaborated here.

[0175] Furthermore, the cleaning equipment is one of the following: a sweeping robot, a mopping robot, a floor scrubbing robot, and a cleaning robot. For example, a sweeping robot, a handheld floor scrubbing robot, and a fully automatic floor scrubbing robot. In this embodiment, the cleaning equipment is a cleaning robot.

[0176] The working process of the cleaning equipment and the disassembly and assembly process of the roller in this embodiment will be described below with reference to the accompanying drawings:

[0177] (I) Work Process

[0178] When the cleaning equipment starts cleaning, it first cleans the edges of the area it is assigned to and then cleans the interior of the area in a bow-shaped pattern. When the telescopic drive 3 rotates forward, it retracts the pull member 4, pulling the second bracket 201 to overcome the tension of the tension spring. When the telescopic positioning detection post 1002 on the second bracket 201 triggers the signal of the telescopic positioning detection device 1001, the telescopic drive 3 stops working. Because the motor itself has a self-locking force, the pull member 4 remains in a tightened state, and the second bracket 201 remains in a retracted state, thus performing cleaning. This is suitable for cleaning the interior area of ​​the entire machine (not cleaning along the edges).

[0179] When the machine is cleaning along the edges, the telescopic drive 3 is reversed for a certain period of time T1. T1 should be less than the time required for the winding wheel to rotate in the opposite direction to prevent the pulling member 4 from being wound backwards onto the winding wheel after release. The purpose of reversing is to unlock the pulling member 4. During reversal, the telescopic drive 3 loses its locking force on the pulling member 4, and under the force of the tension spring, the second bracket 201 will return to the extended state. This state is suitable for cleaning hard-to-reach corners such as walls, table and chair corners.

[0180] (II) Roller disassembly and assembly process

[0181] like Figures 4-11 , Figures 13-18 As shown, after prolonged use, the roller 202 needs to be replaced. At this time, the user presses button 9 in the x direction. Button 9 pushes the second end of the locking member 14, causing the locking member 14 to rotate. The first elastic member 15 is compressed, and the torque of the first elastic member 15 increases until the hook 1401 disengages from the groove 601. At this time, the cover 6 is unlocked. Under the action of the restoring force of the second elastic member 2203, the first housing 2201 is ejected by the second elastic member 2203 and moves away from the second housing 2202. The first housing 2201 pushes the sleeve 12, the first mounting member 19, and the roller 202 to eject the second bracket 202 together. At this time, the user can release button 9 and take out the old roller 202. Then, press button 9 to make the hook 1401 move aside, insert the new roller 202 into the second bracket 201 to the installation position, release button 9, and make the hook 1401 engage with the groove 601 to complete the installation of the new roller 202.
