[0114] Specifically, a rotating shaft 16 is sleeved on the middle part of the locking member 14, and the locking member 14 has two oppositely arranged ends, namely a first end and a second end. The first end is a hook 1401 for locking / unlocking the cover body 6, and the second end abuts against the button 9. Correspondingly, the cover body 6 has a groove 601 that is engaged with the hook 1401.

[0115] When the user presses button 9 inward (such as Figure 7 When the user releases the button 9, the button 9 overcomes the torque of the first elastic member 15, pushes the locking member 14 to rotate around the rotating shaft 16, and the hook 1401 is disengaged from the groove 601, and the cover 6 is unlocked; and when the user releases the button 9, the button 9 moves outward (as shown in the arrow x direction) under the action of the elastic restoring force of the first elastic member 15. Figure 7 The locking member 14 returns to the locking 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 does not engage with the groove 601.

[0116] Furthermore, the locking assembly further comprises a locking member guiding mechanism, which is disposed between the locking member 14 and the third bracket 7 , and is used to limit a 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, and prevent the locking member 14 from being disengaged from the installation position. When assembling the locking assembly, the locking member guide mechanism can also be used to assist the installation of the locking member 14 and improve assembly efficiency.

[0118] In this embodiment, the second end of the locking member 14 is arranged opposite to the hook 1401 , and the locking member guide mechanism is arranged at the second end of the locking member 14 . The rotation track of the second end is an arc.

[0119] Furthermore, the locking member guiding mechanism includes a guide column 1701 and a guide groove 1702 that are slidably matched, one of the guide column 1701 and the guide groove 1702 is arranged on the locking member 14 , and the other one is arranged on the third bracket 7 .

The extension direction of the guide groove 1702 matches the rotation track of the locking member 14.

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

[0122] Furthermore, two locking members 14 are provided, and the two locking members 14 are symmetrically arranged relative to the moving direction of the button 9 .

[0123] In this embodiment, two rollers 202 are provided. Accordingly, the roller disassembly structure includes two covers 6. One cover 6 is provided at one end of each roller 202. The third bracket 7 is placed between the two rollers 202. Two locking members 14 are provided. The two locking members 14 are respectively used to lock / unlock one cover 6, so that one button 9 can simultaneously install and remove two rollers 202. The moving direction of the button 9 is as follows: Figure 7 As shown by the arrows xx', the two locking members 14 are symmetrically arranged relative to the moving direction of the key 9, so as to facilitate the structural arrangement, make the structure compact and reduce 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 a moving trajectory of the button 9 .

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

[0126] In this embodiment, the key guide mechanism includes a guide rib 1801 and a guide hole 1802 that are slidably matched, one of the guide rib 1801 and the guide hole 1802 is arranged on the key 9 , and the other is arranged on the third bracket 7 .

The key guide mechanism of this structure does not take up too much setting space, is conducive to improving the reliability of the structure, and can be compactly arranged.

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

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

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

[0131] In this embodiment, the key limiting mechanism includes a limiting buckle 23, which is arranged on the key 9 and protrudes from the surface of the key 9. Accordingly, a limiting groove is arranged on the third bracket 7, and the limiting buckle 23 can be engaged with the limiting groove to limit the key 9. Specifically, the limiting buckle 23 is arranged on the top surface of the key 9 to avoid interference with other structural components.

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

[0133] When the cover 6 is connected to one end of the drum 202 , the cover 6 will not rotate with the drum 202 to avoid affecting the cleaning work of the drum 202 , and at the same time, the drum 202 can be reliably protected.

[0134] The rotation limiting assembly is used to prevent the cover body 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, and the other is fixed to the cover body 6.

[0135] In this embodiment, the first mounting member 19 is fixed to one end of the roller 202 connected to the cover body 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 body 6, so that the first mounting member 19 can rotate with the roller 202, while the cover body 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 body 6 .

[0137] In order to facilitate the installation of the structure, the rotation limiting assembly further includes a fixed shaft 21, and one of the inner ring and the outer ring of the bearing 20 is fixed to the first mounting member 19 via the fixed shaft 21. 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, so as to facilitate the connection setting of the structure.

[0138] In order to improve the connection reliability, the fixed shaft 21 is tightly fitted with the first mounting member 19, the fixed shaft 21 is tightly fitted with the inner ring of the bearing 20, and the outer ring of the bearing 20 is tightly fitted with the cover 6. At the same time, the cover 6 is also buckled with the outer ring of the bearing to prevent the cover 6 from coming out in the axial direction.

[0139] Furthermore, the drum disassembly and assembly structure also includes a cover circumferential limiting mechanism, which is arranged between the cover 6 and the second bracket 201 and is used to prevent the cover 6 from circumferentially rotating relative to the second bracket 201 .

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

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

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

[0143] Furthermore, the pop-up assembly includes a first shell 2201, a second shell 2202 and a second elastic member 2203, the second elastic member 2203 is arranged between the first shell 2201 and the second shell 2202, and one end of the second elastic member 2203 abuts against the first shell 2201, and the other end abuts against the second shell 2202, and the end of the first shell 2201 away from the second shell 2202 abuts against or separates from the roller 202; when the locking member 14 of the locking assembly switches from the unlocking position to the locking position, the end of the first shell 2201 away from the second shell 2202 abuts against the roller 202, the first shell 2201 moves toward the direction close to the second shell 2202, and the second elastic member 2203 is compressed; when the locking member 14 switches from the locking position to the unlocking position, the second elastic member 2203 is reset, the first shell 2201 moves away from the second shell 2202, and the end of the first shell 2201 away from the second shell 2202 is ejected from the roller 202.

[0144] like Fig.12 As shown, the pop-up assembly is arranged at the other end of the drum 202, and the output shaft 501 of the rotary driving member 5 at this end is transmission-connected with the drum 202, thereby driving the drum 202 to rotate.

[0145] The pop-up assembly includes a first shell 2201, a second shell 2202 and a second elastic member 2203. The first shell 2201 and the second shell 2202 are sleeved on the output shaft 501 of the rotating drive member 5. The first shell 2201 and the second shell 2202 are buckled together, and the first shell 2201 can move in the direction of approaching / moving away from the second shell 2202, but the first shell 2201 cannot be separated from the second shell 2202. The second shell 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, and the snap-fit ​​mechanism is used to prevent the first housing 2201 from being separated from the second housing 2202 when the locking member 14 is switched from the locked position to the unlocked position, so that the first housing 2201 can move toward the direction close to the second housing 2202 or move away from the second housing 2202, but the first housing 2201 cannot be separated 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 member 2203 is disposed between the first shell 2201 and the second shell 2202, and one end of the second elastic member 2203 abuts against the first shell 2201, and the other end abuts against the second shell 2202. Specifically, a mounting column is provided at the inner center of the second shell 2202, and the second elastic member 2203 is sleeved on the mounting column, so that the second elastic member 2203 can be centrally disposed, so that the elastic force is stable, which is conducive to the balanced force of the drum 202. When the drum 202 is installed, the first shell 2201 moves toward the direction close to the second shell 2202, and the second elastic member 2203 is compressed. When the drum 202 is removed, the first shell 2201 is ejected under the elastic restoring force of the second elastic member 2203, and the first shell 2201 moves toward the direction away from the second shell 2202, and the first shell 2201 drives the drum 202 to pop out of the second bracket 201, so that the user can take it for replacement.

[0147] One end of the first housing 2201 away from the second housing 2202 is in contact with or separated from the drum 202. In this embodiment, a sleeve 12 and a second mounting member 24 are further provided on the output shaft 501. The sleeve 12 and the second mounting member 24 are fixed to the drum 202. The sleeve 12 and the second mounting member 24 can rotate with the drum 202, and the sleeve 12 and the second mounting member 24 can reciprocate along the axial direction of the output shaft 501 with the drum 202. One end of the first housing 2201 away from the second housing 2202 is in contact with or separated from the sleeve 12 to eject the drum 202.

[0148] A limit pin 25 is provided at the end of the output shaft 501 to prevent the sleeve 12 from slipping out of the output shaft 501, causing the roller 202 to be ejected too far. A structure that can pass over the limit pin 25 is provided on the second mounting member 24, such as a through hole, and an interference fit structure, such as an interference fit sealing ring, is provided 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 time, the user needs to pull out the roller 202 with force to separate the second mounting member 24 from the sleeve 12, thereby taking out the roller 202.

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

[0150] The roller assembly 2 of the cleaning device is disassembled and assembled through the roller disassembly and assembly structure of this embodiment, which is easy to operate and has high disassembly and assembly efficiency. The roller disassembly and assembly structure has a simple structure and occupies a small volume, so that the side of the roller assembly 2 is very thin, which can reduce the distance between the roller and the wall and improve the cleaning effect.

[0151] like Figure 19-20As shown, the cleaning device further comprises a first bracket 1 and a telescopic drive assembly, wherein the telescopic drive assembly comprises a first control assembly and a second control assembly. A roller assembly 2 is telescopically and movably arranged at the bottom of the first bracket 1 .

[0152] Under the driving control of the telescopic drive component, the roller assembly 2 can be telescopically moved. When cleaning corner areas such as the wall, the force of the second control component on the roller assembly 2 is smaller than the force of the first control component on the roller assembly 2. The first control component drives the roller assembly 2 to extend relative to the first bracket 1, so that the roller assembly 2 is not affected by the position of the first bracket 1 and can be closer to the corner area, so as to achieve "edge cleaning" to effectively clean the corner area, significantly reduce the cleaning blind area, and greatly improve the cleaning effect. When the corner area does not need to be cleaned (that is, when the roller assembly 2 needs to be reset), the force of the second control component on the roller assembly 2 is greater than the force of the first control component on the roller assembly 2, and the second control component drives the roller assembly 2 to retract relative to the first bracket 1. Through the coordinated cooperation of the first control component and the second control component, the position of the roller assembly 2 can be adjusted, so that the controllability of the roller assembly 2 is stronger, and the telescopic movement process of the roller assembly 2 is smoother. This roller assembly structure not only has a better cleaning effect, but also a better user experience.

[0153] The first bracket 1 has a certain structural strength and can support and set the roller assembly 2 and the telescopic drive assembly. Usually, the first bracket 1 is made of waterproof, corrosion-resistant and high-strength materials to ensure the service life of the entire roller structure. Fig.19 and Fig. 20 Taking the perspective of as an example, the bottom of the first bracket 1 faces the surface to be cleaned.

[0154] The roller assembly 2 is telescopically movably arranged on the first bracket 1. The roller assembly 2 is mainly used to clean the surface to be cleaned. When working, the roller assembly 2 is in direct contact with the surface to be cleaned to realize the cleaning process of the surface to be cleaned. The roller assembly 2 is arranged at the bottom of the first bracket 1 and can be telescopically moved relative to the first bracket 1, that is, the position of the roller assembly 2 is not fixed relative to the first bracket 1 and the position can be changed. The roller assembly 2 can be extended relative to the first bracket 1. When the roller assembly 2 is extended to a preset extended position (extended in place), the roller assembly 2 is in an extended state. Correspondingly, the roller assembly 2 can be retracted relative to the first bracket 1. When the roller assembly 2 is retracted to a preset retracted position (retracted in place), the roller assembly 2 is in a retracted state. In other words, the roller assembly 2 can reciprocate between the corresponding positions of the extended state and the retracted state, that is, the roller assembly 2 can move from the retracted state to the extended state, and can also move from the extended state to the retracted state.

[0155] The second bracket 201 is also provided with a first connecting member 204, that is, the first control assembly is connected to the roller assembly 2 through the first connecting member 204. In addition, the second bracket 201 is also provided with a second connecting member 203, and the second control assembly is connected to the roller assembly 2 through the second connecting member 203. Of course, the roller assembly 2 also has other structures and components that the existing roller assembly has, which will not be repeated here.

[0156] In this embodiment, the first connecting member 204 and the second connecting member 203 are respectively located on both sides of the roller assembly 2 to make the structural setting on the roller assembly 2 more balanced and avoid excessive concentration of the structure. When the first control component and the second control component apply force to the roller assembly 2, the telescopic movement of the roller assembly 2 can be smoother.

[0157] The telescopic drive assembly is disposed on the first bracket 1, and the telescopic drive assembly 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, and both the first control assembly and the second control assembly can apply a force to the roller assembly 2 to realize the telescopic movement process of the roller assembly 2. When the force applied by the second control assembly to the roller assembly 2 is less than the force applied by the first control assembly to the roller assembly 2, the first control assembly drives the roller assembly 2 to extend relative to the first bracket 1, and when the force applied by the second control assembly to the roller assembly 2 is greater than the force applied by the first control assembly to the roller assembly 2, the second control assembly drives the roller assembly 2 to retract relative to the first bracket 1.

[0158] That is to say, by adjusting the force exerted by the first control component and the second control component on the roller assembly 2, the roller assembly 2 can be moved to the extended state under the control of the first control component, and the roller assembly 2 can also be moved to the retracted state under the control of the second control component.

[0159] Specifically, the roller assembly 2 is telescopically movably arranged on the side of the first bracket 1 facing the surface to be cleaned, the first control assembly 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 assembly 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 bracket 1 is the side of the first bracket 1 facing the surface to be cleaned, the bottom of the first bracket 1 faces the surface to be cleaned, the roller assembly 2 is telescopically movably arranged at the bottom of the first bracket 1, and 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 bracket 1 on the ground, the first control assembly can drive the roller assembly 2 to extend out of the projection range, and the second control assembly can drive the roller assembly 2 to retract into the projection range. In other words, when the roller assembly 2 is in the retracted state, the roller assembly 2 cannot be seen from the top view of the first bracket 1, and when the roller assembly 2 is in the extended state, at least part of the structure of the roller assembly 2 is placed outside the first bracket 1. This roller structure is suitable for cleaning equipment such as a sweeper, which is conducive to simplifying the structural design, reducing the control difficulty, and facilitating 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 bracket 1.

[0161] The first control assembly and the second control assembly are both disposed on the first bracket 1 , but the first control assembly is disposed above one of the rollers 202 , while the second control assembly is disposed above the other roller 202 .

[0162] When the first control component and the second control component apply force to the first bracket 1, the force direction of the first control component on the roller assembly 2 is parallel to and does not overlap with the force direction of the second control component on the roller assembly 2, thereby realizing the dispersed setting of the first control component and the second control component, making full use of the setting space on the first bracket 1, and making the force on the roller assembly 2 more balanced, which is beneficial to the stable driving of the telescopic drive component on the roller assembly 2, making the telescopic movement process of the roller assembly 2 smoother.

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

[0164] The first control assembly includes a control member 8 , which is disposed on the first bracket 1 . The control member 8 applies a pulling force to the roller assembly 2 along the extending direction of the roller assembly 2 .

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

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

[0167] Specifically, the pulling member 4 is arranged on the first bracket 1 in a U-shaped form to make full use of the installation space on the first bracket 1. In addition, the pulling member 4 adopts a steel wire rope, which is wound on the winding wheel. One end of the pulling member 4 is connected to the output end of the telescopic driving member 3, and the other end of the pulling member 4 is connected to the second connecting member 203. The telescopic driving member 3 is used to provide power so that the second control component can apply a force to the roller assembly 2. One end of the pulling member 4 is driven by the telescopic driving member 3, and the other end of the pulling member 4 is connected to the roller assembly 2 through the second connecting member 203. The pulling member 4 is used to pull the roller assembly 2, and by overcoming the force of the first control component on the roller assembly 2, the roller assembly 2 is driven to retract relative to the first bracket 1.

[0168] In this embodiment, the control member 8 is an elastic member, and when the roller assembly is retracted relative to the first bracket 1, the control member 8 is in a stretched state.

[0169] Fig.19 The arrow a in the middle is the extension direction. Fig. 20 The middle arrow b indicates the retracting direction. In this embodiment, the control member 8 is an elastic member, and when the roller assembly 2 is retracted relative to the first bracket 1, the control member 8 is in a stretched state. Specifically, the control member 8 is a tension spring, and when the telescopic driving member 3 is not working, the roller assembly 2 is subjected to the force of the tension spring and will maintain a normal extended state.

[0170] One end of the control member 8 is connected to the first bracket 1, and the other end is connected to the roller assembly 2 through the first connecting member 204. When the roller assembly 2 is retracted relative to the first bracket 1, the control member 8 is in a stretched state, and the control member 8 can apply a pulling force to the roller assembly 2 to move in the extending direction. When the pulling member 4 is released, under the pulling force of the control member 8, the roller assembly 2 is extended relative to the first bracket 1 until it reaches the preset extended position. The pulling force value of the tension spring on the roller assembly 2 is variable. When the roller assembly 2 moves toward the preset retracted position, the pulling force value of the tension spring on the roller assembly 2 gradually increases, and when the roller assembly 2 moves toward the preset extended position, the pulling force value of the tension spring on the roller assembly 2 gradually decreases, but it is necessary to keep the roller assembly 2 at the preset extended position.

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

[0172] In order to make the telescopic movement of the roller assembly 2 smoother and more reliable, a guide rail mechanism is arranged between the first bracket 1 and the second bracket 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 arranged between the first bracket 1 and the second bracket 201, which can save setting space and make the overall structure more compact and reasonable. At the same time, the roller assembly 2 can telescopically move more stably relative to the first bracket 1.

[0173] When cleaning corner areas such as the wall, the force of the second control component on the roller component 2 is smaller than the force of the first control component on the roller component 2. The first control component drives the roller component 2 to extend relative to the first bracket 1, so that the roller component 2 is not affected by the position of the first bracket 1 and can be closer to the corner area, so as to achieve "edge cleaning" to effectively clean the corner area, significantly reduce the cleaning blind area, and greatly improve the cleaning effect. When the corner area does not need to be cleaned (that is, when the roller component 2 needs to be reset), the force of the second control component on the roller component 2 is greater than the force of the first control component on the roller component 2, and the second control component drives the roller component 2 to retract relative to the first bracket 1. Through the coordinated cooperation of the first control component and the second control component, the position of the roller component 2 can be adjusted, so that the controllability of the roller component 2 is stronger, and the telescopic movement process of the roller component 2 is smoother. This roller structure not only has a better cleaning effect, but also a better user experience.

[0174] Of course, the cleaning device also has other structural components that all existing cleaning devices have, which will not be described in detail here.

[0175] Further, the cleaning device is one of a sweeper, a mop, a scrubber and a cleaning robot, for example, a sweeper robot, a handheld scrubber and a fully automatic scrubber robot, etc. In this embodiment, the cleaning device is a cleaning robot.

[0176] The working process of the cleaning device of this embodiment and the disassembly and assembly process of the drum are described below in conjunction with the accompanying drawings:

[0177] (I) Working process

[0178] When the cleaning device starts cleaning, it will first clean the edges of the area and then clean the interior of the area in a bow shape. When the telescopic drive member 3 rotates forward, the pulling member 4 will be retracted, pulling the second bracket 201 to overcome the tension of the tension spring to do work. When the telescopic in-place detection column 1002 on the second bracket 201 triggers the signal of the telescopic in-place detection member 1001, the telescopic drive member 3 stops working. Because the motor itself has a self-locking force, the pulling member 4 is still in a tightened state, and the second bracket 201 remains in a retracted state for cleaning. This is suitable for the case where the whole machine is cleaning the internal area (not cleaning along the edges).

[0179] When the whole machine is cleaning along the edge, the telescopic drive member 3 is controlled to reverse for a certain time T1, and T1 should be less than the time taken for the winding wheel to rotate in the opposite direction, so as to prevent the pulling member 4 from being reversely wound on the winding wheel after being released. The purpose of the reversal is to unlock the pulling member 4. When reversing, the telescopic drive member 3 loses the locking force on the pulling member 4, and under the force of the tension spring, the second bracket 201 will be reset to the extended state. This state is suitable for cleaning blind spots such as walls, corners of tables and chairs along the edge.

[0180] (II) Drum disassembly and assembly process

[0181] like Figure 4-Figure 11 , Figure 13-Figure 18 As shown, the roller 202 needs to be replaced after being used for a long time. At this time, the user presses the button 9 in the direction x, and the button 9 pushes the second end of the locking member 14 to rotate the locking member 14, and the first elastic member 15 is compressed, and the torque of the first elastic member 15 increases until the hook 1401 is disengaged from the groove 601. At this time, the cover body 6 is unlocked, and under the action of the restoring force of the second elastic member 2203, the first shell 2201 is ejected by the second elastic member 2203 and moves in the direction away from the second shell 2202. The first shell 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 the button 9 and take out the old roller 202; thereafter, press the button 9 to make the hook 1401 evade, insert the new roller 202 into the second bracket 201 to the installation position, release the button 9 to make the hook 1401 snap into the groove 601, and complete the installation of the new roller 202.

[0182] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
