[0089] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0090] The following is combined with Figures 1-19 This describes embodiments of the roller mounting structure, roller assembly, and cleaning equipment of this utility model.
[0091] According to an embodiment of the present invention, in a first aspect, a roller mounting structure is provided for mounting a roller assembly 1 of a cleaning device. The roller assembly 1 includes a roller bracket 101 and at least two rollers 102. The rollers 102 are detachably disposed within the roller bracket 101. The roller mounting structure includes an end cap 2 and a locking component. The end cap 2 is disposed at one end of the rollers 102 and simultaneously covers and connects with all rollers 102. The locking component is disposed within the roller bracket 101 and is used to lock / unlock the end cap 2 to detach and install the rollers 102.
[0092] This roller mounting structure includes end caps 2 and locking components. The end caps 2 simultaneously cover and connect with all rollers 102. Together with the locking components, all rollers 102 can be easily locked or unlocked simultaneously, enabling the simultaneous disassembly and installation of multiple rollers 102. This is convenient, quick, and easy, significantly improving the replacement efficiency of the rollers 102 and reducing manufacturing costs. Furthermore, the overall structure of the roller mounting structure is relatively simple, reducing the possibility of end cap loosening or shifting, making it less prone to damage, structurally stable, and highly reliable, thus reducing the failure rate of the roller assembly and ensuring its service life. Because the roller structure of this embodiment is stable and reliable, it ensures close contact between the rollers 102 and the surface to be cleaned (such as the ground), improving the cleaning effect.
[0093] The roller mounting structure is used in cleaning equipment, such as dual-roller sweepers, dual-roller handheld floor scrubbers, floor cleaning robots, and other cleaning equipment. The cleaning equipment includes a roller assembly 1, which includes a roller bracket 101 and a roller 102. The roller 102 is detachably mounted in the roller bracket 101, and the roller 102 can be easily disassembled and replaced using the roller mounting structure of this embodiment.
[0094] Specifically, the roller assembly 1 has a generally elongated strip-shaped structure. The roller bracket 101, also known as a telescopic bracket, is the shell structure of the roller assembly 1. The roller bracket 101 has a certain structural strength and can support and mount the roller 102, etc. Furthermore, structural components such as a dirt collection tank and a water channel plate can also be installed on the roller bracket 101. The roller 102 is installed inside the roller bracket 101 and is the roller mop. At least two rollers 102 are provided, such as two, three, or four. In this embodiment, the roller structure is a double-roller structure, meaning there are two rollers 102. The rollers 102 are located on the side of the roller bracket 101 facing the surface to be cleaned. When the cleaning equipment is working, the rollers 102 can rotate and roll to clean the surface. The roller mounting 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.
[0095] The roller mounting structure includes an end cap 2 and a locking assembly. The end cap 2 is located at one end of the roller 102 and is used to seal one end of the roller 102, making the overall appearance more aesthetically pleasing and neat, and preventing dust, debris, etc., from entering the interior of the roller 102, affecting its operation and service life. Furthermore, through the cooperation of the end cap 2 and the locking assembly, all rollers 102 can be easily installed, simplifying operation and improving installation efficiency. In this embodiment, only one end cap 2 is used, which can simultaneously cover and connect with all rollers 102, thereby improving assembly efficiency and simplifying operation.
[0096] A locking assembly is disposed within the roller bracket 101. This assembly is used to lock / unlock the end cap 2 to assemble and disassemble the roller 102. The locking assembly secures the end cap 2 to the roller bracket 101. Since the end cap 2 is located at one end of the roller 102, this locks the roller 102 to the roller bracket 101, thus enabling the installation of the roller 102. Figure 1 As shown; furthermore, the locking assembly enables the end cap 2 to unlock from the roller bracket 101. Since the end cap 2 is located at one end of the roller 102, the roller 102 is unlocked from the roller bracket 101, thereby enabling the disassembly of the roller 102, as shown. Figure 2 As shown.
[0097] Furthermore, the roller mounting structure also includes an end cap circumferential limiting mechanism, which is used to prevent the end cap 2 from rotating circumferentially relative to the roller bracket 101.
[0098] Before the roller 102 is locked to the roller support 101, in order to prevent the end cover 2 from rotating circumferentially relative to the roller support 101 and causing the roller 102 to shift, a circumferential limiting mechanism for the end cover 2 is provided between the end cover 2 and the roller support 101. This can improve the reliability of the installation structure, improve the assembly efficiency of the end cover 2, and simplify the operation.
[0099] Furthermore, the end cap circumferential limiting mechanism includes a limiting protrusion 3 and a limiting groove that fit together. The limiting protrusion 3 is disposed on one of the end cap 2 and the roller bracket 101, and the limiting groove is disposed on the other.
[0100] The end cap circumferential limiting mechanism includes a limiting protrusion 3 and a limiting groove that fit together. The limiting protrusion 3 can be disposed on either the end cap 2 or the roller bracket 101, and correspondingly, the limiting groove is disposed on the other. In this embodiment, the limiting protrusion 3 is disposed on the side of the end cap 2 facing the roller 102, and the limiting groove is disposed at the corresponding position on the roller bracket 101. The limiting protrusion 3 can be inserted into the limiting groove to prevent the end cap 2 from rotating circumferentially relative to the roller bracket 101, thereby improving the reliability of the structure.
[0101] Furthermore, each end cap 2 is provided with a limiting protrusion 3 near each roller 102, so that the end cap 2 can be circumferentially limited near each roller 102, further improving structural reliability and facilitating the installation of roller 102.
[0102] Furthermore, the end cap circumferential limiting mechanism also includes a circumferential limiting stop 201 and a stop block that abut against each other. The circumferential limiting stop 201 is disposed on one of the end cap 2 and the roller bracket 101, and the stop block is disposed on the other. This end cap circumferential limiting mechanism has a relatively simple structure, occupies little space, is conducive to the compactness of the structure, and has good reliability.
[0103] like Figure 3As shown, in this embodiment, the circumferential limiting stop 201 is provided on the side of the end cover 2 facing the roller 102, and the stop block is provided on the roller bracket 101. After the stop block abuts against the circumferential limiting stop 201, it can circumferentially limit the end cover 2, prevent the end cover 2 from rotating circumferentially relative to the roller bracket 101, and improve the installation reliability and installation efficiency.
[0104] Furthermore, the end cap 2 is provided with a circumferential limiting stop 201 near each roller 102, so that the end cap 2 can be circumferentially limited near each roller 102, thereby improving the structural reliability and facilitating the installation of the roller 102.
[0105] Furthermore, the locking assembly includes a locking bracket 4, a button 5, and at least one locking member 6. The locking bracket 4 is disposed on the roller bracket 101, and the button 5 and the locking member 6 are disposed on the locking bracket 4. The locking member 6 has a locked position for locking the end cover 2 and an unlocked position for unlocking the end cover 2. The button 5 is connected to the locking member 6 and switches the locking member 6 between the locked position and the unlocked position.
[0106] like Figures 7-19 As shown, the locking bracket 4 serves as the support for the locking assembly, and components such as the button 5 and the locking element 6 are all mounted on the locking bracket 4. The locking bracket 4 is located on the roller bracket 101, with most of its structure situated inside the roller bracket 101. The button 5 is movably mounted on the locking bracket 4, with its operating surface located on the outer side of the locking bracket 4 for easy user pressing. In this embodiment, the movement trajectory of the button 5 is linear. The locking bracket 4, equipped with the button 5 and at least one locking element 6, forms a modular structure, facilitating assembly and improving assembly efficiency.
[0107] The locking element 6 is located inside the locking bracket 4. The locking element 6 has a locked position for locking the end cover 2 and an unlocked position for unlocking the end cover 2. The button 5 is connected to the locking element 6 to control its movement. Under the control of the button 5, the locking element 6 switches between the locked and unlocked positions. When the locking element 6 is in the locked position, it locks the end cover 2, and the roller 102 is installed in place. When the locking element 6 is in the unlocked position, the end cover 2 is unlocked, and the roller 102 pops out of the roller bracket 101 under the action of the pop-out component, facilitating user replacement.
[0108] Furthermore, the locking member 6 is rotatably disposed within the locking bracket 4, and the locking assembly also includes a first elastic member 7. The first elastic member 7 is sleeved on the pivot 8 of the locking member 6. One end of the first elastic member 7 abuts against the locking bracket 4, and the other end abuts against the locking member 6. The first elastic member 7 applies a force to the locking member 6 to rotate toward the locking position.
[0109] The locking member 6 is rotatably disposed within the locking bracket 4. In this embodiment, the locking member 6 is rotatably disposed within the locking bracket 4 around the rotating shaft 8, which is disposed vertically within the locking bracket 4. The locking member 6 can rotate around the rotating shaft 8 under the control of the button 5 to switch between the locked position and the unlocked position.
[0110] The first elastic element 7 is sleeved on the rotating shaft 8. The first elastic element 7 is a torsion spring. One end of the first elastic element 7 abuts against the locking bracket 4, and the other end abuts against the locking member 6. The first elastic element 7 can apply a force to the locking member 6 to make it rotate toward the locked position. Specifically, the rotating shaft 8 is sleeved in the middle of the locking member 6.
[0111] Furthermore, the locking member 6 has a first end and a second end that are arranged opposite to each other. The first end is used to lock / unlock the end cover 2, and the second end abuts against the button 5.
[0112] The locking member 6 has two opposite ends, namely a first end and a second end. The first end is a hook 601 for locking / unlocking the end cover 2, and the second end abuts against the button 5 so that the roller can be disassembled and assembled by operating the button 5.
[0113] When the user presses button 5 inward (e.g.) Figure 13 (As shown by arrow X), button 5 overcomes the torque of the first elastic element 7, pushing the locking element 6 to rotate around the pivot 8, causing the hook 601 to disengage from the slot 301, and the end cover 2 to unlock; when the user releases button 5, under the elastic restoring force of the first elastic element 7, button 5 moves outward (as shown by arrow X). Figure 13 (As shown by arrow X' direction), the locking part 6 returns to the locked position, the hook 601 engages with the slot 301, locking the end cover 2. However, if a new roller 102 is not installed at this time, the hook 601 will not engage with the slot 301.
[0114] Furthermore, the limiting protrusion 3 of the end cover circumferential limiting mechanism has a slot 301, and the first end engages with the slot 301 to lock / unlock the end cover 2.
[0115] like Figure 2 As shown, the limiting protrusion 3 has a slot 301, and the hook 601 can engage with the slot 301. When the hook 601 enters the slot 301 and engages, the locking member 6 is in a locked state, and the roller 102 is locked in place. When the hook 601 disengages from the slot 301, the locking member 6 is in an unlocked state, and the roller 102 is removed.
[0116] Furthermore, there are two rollers 102, two limiting protrusions 3, and the openings of the two slots 301 are arranged opposite each other. There are two locking parts 6, and the two locking parts 6 are symmetrically arranged relative to the moving direction of the button 5.
[0117] In this embodiment, two rollers 102 are provided and are arranged in parallel. Correspondingly, two limiting protrusions 3 are also provided, and the openings of the two slots 301 are arranged opposite to each other. Two locking members 6 are provided and are arranged symmetrically relative to the moving direction of the button 5, so that the two locking members 6 can cooperate with the two slots 301. This installation structure is compact and reasonable, and can reduce the structural volume.
[0118] Furthermore, the end cap circumferential limiting mechanism also includes a first limiting edge 2101, a second limiting edge 2102, and a third limiting edge 2103. The first limiting edge 2101, the second limiting edge 2102, and the third limiting edge 2103 are disposed on the roller bracket 101 or the button 5. The end cap 2 has an end cap notch 203 with one end open in the middle. The first limiting edge 2101, the second limiting edge 2102, and the third limiting edge 2103 all abut against the inner wall of the end cap notch 203.
[0119] like Figure 2 As shown, the end cap 2 has an end cap notch 203 with one open end in the middle, and the end cap notch 203 is located between the connection position of the two rollers 102 and the end cap 2. The upper part of the end cap notch 203 is open, and the button 5 is embedded in the end cap notch 203. After the roller bracket 101, roller 102, end cap 2, and button 5 are assembled, the outer surfaces of the end cap 2 and the button 5 are flush. In addition, there is a protruding structure of the roller bracket 101 between the bottom edge of the button 5 and the bottom wall (bottom inner wall) of the end cap notch 203, so as to make the fit of the button 5, the end cap 2, and the roller bracket 101 tighter.
[0120] In this embodiment, the first limiting edge 2101 and the second limiting edge 2102 are the two vertical side edges of the button 5, while the third limiting edge 2103 is the protruding structure of the roller bracket 101. The first limiting edge 2101, the second limiting edge 2102 and the third limiting edge 2103 all abut against the inner wall of the end cover notch 203, thereby further limiting the end cover 2 in the circumferential direction.
[0121] Furthermore, the roller mounting structure also includes a rotation limiting component, which is disposed between the end cover 2 and the roller 102. The rotation limiting component is used to prevent the end cover 2 from rotating with the roller 102.
[0122] When the end cap 2 is connected to one end of the roller 102, the end cap 2 will not rotate with the roller 102 to avoid affecting the cleaning operation of the roller 102, and at the same time, it can provide reliable protection for the roller 102.
[0123] Furthermore, the rotation limiting assembly includes a first mounting member 9 and a bearing 10. The first mounting member 9 is fixed to the roller 102, and one of the inner ring and the outer ring of the bearing 10 is fixed to the first mounting member 9, while the other is fixed to the end cap 2.
[0124] The rotation limiting assembly is used to prevent the end cap 2 from rotating with the roller 102. Specifically, the rotation limiting assembly includes a first mounting member 9 and a bearing 10. The first mounting member 9 is fixed to the roller 102, and one of the inner ring and the outer ring of the bearing 10 is fixed to the first mounting member 9, while the other is fixed to the end cap 2.
[0125] like Figures 5-6 As shown, in this embodiment, the first mounting member 9 is fixed to one end of the end cover 2 of the roller 102, the inner ring of the bearing 10 is fixed to the first mounting member 9, and the outer ring of the bearing 10 is fixed to the end cover 2, so that the first mounting member 9 can rotate with the roller 102, while the end cover 2 will not rotate with the roller 102.
[0126] In other embodiments, the outer ring of the bearing 10 may be fixed to the first mounting member 9, and the inner ring may be fixed to the end cap 2.
[0127] Furthermore, the rotation limiting assembly also includes a fixed shaft 11, and one of the inner and outer rings of the bearing 10 is fixed to the first mounting member 9 via the fixed shaft 11.
[0128] To facilitate structural installation, the rotation limiting assembly also includes a fixed shaft 11, through which one of the inner and outer rings of the bearing 10 is fixed to the first mounting member 9. In this embodiment, the first mounting member 9 is connected and fixed to the fixed shaft 11, and the fixed shaft 11 is also fixed to the inner ring of the bearing 10, thereby facilitating the connection and arrangement of the structure.
[0129] To improve connection reliability, the fixed shaft 11 is interference-fitted with the first mounting part 9, the fixed shaft 11 is interference-fitted with the inner ring of the bearing 10, and the outer ring of the bearing 10 is interference-fitted with the end cover 2. At the same time, the end cover 2 is also fastened to the outer ring of the bearing to prevent the end cover 2 from coming off axially.
[0130] Furthermore, the end cap 2 is provided with an assembly groove 202 on the side facing the roller 102, and the bearing 10 is placed in the assembly groove 202.
[0131] like Figure 4 As shown, an assembly post 204 is provided on the side of the end cap 2 facing the roller 102. The assembly post 204 protrudes from the inner side of the end cap 2 and has an assembly groove 202 inside. The opening of the assembly groove 202 faces the roller 102. The bearing 10 is disposed in the assembly groove 202, as shown. Figure 6 As shown, this is to facilitate the stable installation of the bearing 10 and to facilitate the fixed connection between the bearing 10 and the fixed shaft 11 and the end cover 2.
[0132] In addition, the locking assembly also includes a locking member guide mechanism, which is disposed between the locking member 6 and the locking bracket 4. The locking member guide mechanism is used to limit the rotation trajectory of the locking member 6.
[0133] The locking guide mechanism is used to limit the rotation trajectory of the locking part 6, improve the reliability of the rotation of the locking part 6, prevent the locking part 6 from falling out of the installation position, and also assist in the installation of the locking part 6 when assembling the locking assembly, thereby improving the assembly efficiency.
[0134] In this embodiment, the second end of the locking member 6 is disposed opposite to the hook 601 (first end), and the locking member guide mechanism is disposed at the second end of the locking member 6, the rotation trajectory of the second end being arc-shaped.
[0135] like Figure 11 As shown, specifically, the locking member guiding mechanism includes a slidingly fitted guide post 1601 and a guide groove 1602, one of which is disposed on the locking member 6, and the other is disposed on the locking bracket 4.
[0136] In this embodiment, a guide post 1601 is disposed on the locking member 6, and a guide groove 1602 is disposed on the locking bracket 4. The guide post 1601 is disposed at the second end of the locking member 6 and is arranged vertically. The guide groove 1602 is formed in the locking bracket 4, and the lower end of the guide post 1601 is slidably placed in the guide groove 1602. The extending direction of the guide groove 1602 matches the rotation trajectory of the locking member 6.
[0137] In other embodiments, the guide post 1601 can also be provided on the locking bracket 4, and the guide groove 1602 can be provided on the locking member 6, as long as the rotation trajectory of the locking member 6 can be limited, so as to improve the reliability of the mechanism.
[0138] In addition, the locking assembly also includes a button guide mechanism, which is disposed between the button 5 and the locking bracket 4. The button guide mechanism is used to limit the movement trajectory of the button 5.
[0139] The button guide mechanism is used to limit the movement trajectory of button 5, so that button 5 can move in its movement direction, preventing the position of button 5 from shifting after long-term use and improving the reliability of the structure.
[0140] In this embodiment, the button guiding mechanism includes a slidingly engaged guide rib 1701 and a guide hole 1702. One of the guide rib 1701 and the guide hole 1702 is disposed on the button 5, and the other is disposed on the locking bracket 4.
[0141] Specifically, guide rib 1701 is disposed on locking bracket 4, and guide hole 1702 is disposed on button 5. Guide rib 1701 can be inserted into guide hole 1702 to limit the movement trajectory of button 5. The extension direction of guide rib 1701 is in 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 structure.
[0142] In other embodiments, the guide rib 1701 may also be provided on the button 5, and the guide hole 1702 may be provided on the locking bracket 4.
[0143] In addition, the locking assembly also includes a button limiting mechanism, which is disposed on the button 5 and the locking bracket 4. The button limiting mechanism is used to prevent the button 5 from dislodging from the locking bracket 4.
[0144] When the user releases button 5, button 5 will move outward under the elastic restoring force of the first elastic element 7 (arrow X' direction). In order to prevent button 5 from coming out of the locking bracket 4, a button limiting mechanism is provided to improve the reliability of the structure.
[0145] like Figure 12 As shown, in this embodiment, the button limiting mechanism includes a limiting buckle 18, which is disposed on the button 5 and protrudes from the surface of the button 5. Correspondingly, a limiting groove is provided on the locking bracket 4, and the limiting buckle 18 can engage with the limiting groove to limit the button 5. Specifically, the limiting buckle 18 is disposed on the top surface of the button 5 to avoid interference with other structural components.
[0146] Furthermore, the roller mounting structure also includes a pop-out component, which is located at the other end of the roller 102. When the locking component unlocks the end cover 2, the pop-out component pops the roller 102 out of the roller bracket 101.
[0147] The pop-out component is located at the other end of the roller 102. When the locking component unlocks the end cover 2, the pop-out component pushes the roller 102 out of the roller bracket 101, making it convenient for the user to take the roller 102 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 102, they do not affect or interfere with each other, making the distance between both ends of the roller 102 and the wall relatively small. This allows the roller 102 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.
[0148] like Figure 4As shown, in this embodiment, the pop-out component includes a first housing 1201, a second housing 1202, and a second elastic member 1203. The second elastic member 1203 is disposed between the first housing 1201 and the second housing 1202, with one end of the second elastic member 1203 abutting against the first housing 1201 and the other end abutting against the second housing 1202. The end of the first housing 1201 away from the second housing 1202 abuts against or separates from the roller 102. When the locking member 6 of the locking component switches from the unlocked position to the locked position, the end of the first housing 1201 away from the second housing 1202 abuts against the roller 102, and the first housing 1201 moves toward the second housing 1202, compressing the second elastic member 1203. When the locking member 6 switches from the locked position to the unlocked position, the second elastic member 1203 resets, and the first housing 1201 moves away from the second housing 1202, with the end of the first housing 1201 away from the second housing 1202 pushing out of the roller 102.
[0149] Specifically, the ejector assembly is located at the other end of the roller 102, where the output shaft 13 of the rotation drive is connected to the roller 102, thereby driving the roller 102 to rotate. The first housing 1201 and the second housing 1202 are sleeved on the output shaft 13 of the rotation drive, and the first housing 1201 and the second housing 1202 are fastened together. The first housing 1201 can move towards / away from the second housing 1202, but the first housing 1201 cannot detach from the second housing 1202. The second housing 1202 is fixed to the output shaft 13 by a fixing pin 15. Specifically, the edges of the first housing 1201 facing the second housing 1202 and the edges of the second housing 1202 facing the first housing 1201 are connected by a snap-fit mechanism. The snap-fit mechanism is used to prevent the first housing 1201 from disengaging from the second housing 1202 when the locking member 6 switches from the locked position to the unlocked position. This allows the first housing 1201 to move towards or away from the second housing 1202, but the first housing 1201 cannot disengage from the second housing 1202 along the axial direction of the output shaft 13. The second elastic member 1203 is specifically a spring.
[0150] The second elastic element 1203 is disposed between the first housing 1201 and the second housing 1202, with one end of the second elastic element 1203 abutting against the first housing 1201 and the other end abutting against the second housing 1202. Specifically, the second housing 1202 has a mounting post at its internal center, and the second elastic element 1203 is sleeved on the mounting post so that the second elastic element 1203 can be centrally positioned, making the elastic force stable and facilitating the balanced force on the roller 102. When the roller 102 is installed, the first housing 1201 moves towards the second housing 1202, and the second elastic element 1203 is compressed. When the roller 102 is disassembled, under the elastic restoring force of the second elastic element 1203, the first housing 1201 is ejected and moves away from the second housing 1202. The first housing 1201 drives the roller 102 to pop out of the roller bracket 101, making it easy for the user to remove and replace.
[0151] The end of the first housing 1201 away from the second housing 1202 abuts against or separates from the roller 102. In this embodiment, a sleeve 14 and a second mounting member 19 are also provided on the output shaft 13. The sleeve 14 and the second mounting member 19 are fixed to the roller 102. The sleeve 14 and the second mounting member 19 can rotate with the roller 102, and the sleeve 14 and the second mounting member 19 can reciprocate along the axial direction of the output shaft 13 with the roller 102. The end of the first housing 1201 away from the second housing 1202 abuts against or separates from the sleeve 14 to eject the roller 102.
[0152] A limit pin 20 is provided at the end of the output shaft 13 to prevent the sleeve 14 from dislodging from the output shaft 13, which would cause the roller 102 to be ejected too far. A structure, such as a through hole, is provided on the second mounting member 19 that can pass over the limit pin 20. Furthermore, an interference fit structure, such as an interference fit sealing ring, is provided between the sleeve 14 and the second mounting member 19. Under the action of the ejection assembly, the sleeve 14, the second mounting member 19, and the roller 102 are ejected. At this point, the user needs to forcefully pull out the roller 102 to disengage the second mounting member 19 from the sleeve 14, thereby removing the roller 102.
[0153] This embodiment also provides a roller assembly, including a roller bracket 101, at least two rollers 102, and a roller mounting structure as described above, wherein the rollers 102 are mounted via the roller mounting structure.
[0154] The roller assembly includes a roller bracket 101 and rollers 102. In this embodiment, two rollers 102 are provided and arranged in parallel. The rollers 102 are detachably mounted on the bottom of the roller bracket 101. The rollers 102 of this roller assembly are installed via a roller mounting structure. In this roller mounting structure, the end cap 2 can simultaneously cover and connect with all rollers 102. With the locking component, all rollers 102 can be easily locked or unlocked simultaneously, enabling the simultaneous disassembly and installation of multiple rollers 102. This is convenient, quick, and easy, significantly improving roller replacement efficiency. It also simplifies the roller fixing structure, reduces operational difficulty, and because the overall structure of the roller mounting structure is relatively simple, it is not easily damaged, has good structural stability, and high reliability, which helps reduce the failure rate of the roller assembly and ensures its service life.
[0155] This embodiment also provides a cleaning device, including the roller mounting structure as described above or including the roller assembly as described above.
[0156] In this cleaning equipment, the roller assembly 1 is assembled and disassembled using the roller mounting structure of this embodiment, which is simple to operate and highly efficient. The roller mounting structure itself is simple in structure and occupies a small volume. This cleaning equipment also has other structural components common to existing cleaning equipment, which will not be elaborated upon here.
[0157] 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.
[0158] The process of disassembling and assembling the roller of the cleaning equipment in this embodiment will be described below with reference to the accompanying drawings:
[0159] After prolonged use, roller 102 needs to be replaced. At this time, the user presses button 5 in the x direction. Button 5 pushes the second end of locking member 6, causing locking member 6 to rotate. The first elastic member 7 is compressed, and the torque of the first elastic member 7 increases until hook 601 disengages from slot 301. At this time, end cover 2 is unlocked. Under the restoring force of second elastic member 1203, first housing 1201 is ejected by second elastic member 1203 and moves away from second housing 1202. First housing 1201 pushes sleeve 14, first mounting member 9 and all rollers 102 to pop out of roller bracket 101 together. At this time, the user can release button 5 and take out the old roller 102. Then, press button 5 to make hook 601 move aside, insert the new roller 102 into roller bracket 101 to the installation position, release button 5, and make hook 601 engage with slot 301 to complete the installation of the new roller 102.
[0160] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
