[0002] Robotic vacuum cleaners have entered countless homes, helping people clean their floors. In existing technology, some robotic vacuum cleaners are equipped with two sets of drive mechanisms to operate the cleaning components.

[0003] In the existing technology, the solution using two sets of drive mechanisms is costly and requires a large installation space, which is not conducive to reducing the size of the product. Utility Model Content

[0006] In one of the alternative technical solutions, the preset elastic force of the second elastic element is greater than the preset elastic force of the first elastic element; When the cleaning component is in the extended state, the sliding seat is located at the distal end of the translation bracket, and the translation bracket is blocked by the distal stop. When the cleaning component is in the retracted state, the sliding seat is located at the distal end of the translation bracket, which is blocked by the proximal stop. When the cleaning component is in the raised state, the sliding seat is located on the proximal side of the translation bracket, which is blocked by the proximal stop.

[0012] In one of the alternative technical solutions, the wedge-shaped guide is integrally connected to the sliding seat.

[0013] In one of the alternative technical solutions, the thickness of the wedge-shaped guide gradually increases along the direction from the proximal side to the distal side, and the guide slope at the top of the wedge-shaped guide gradually extends upward.

[0014] This utility model also provides a sweeper, including a housing and the cleaning device described in any of the foregoing technical solutions; The drive assembly is connected to the housing, and the bottom surface of the housing is provided with a receiving groove, in which the cleaning assembly is movably assembled; The fixing bracket is installed on the bottom surface of the housing and is located on one side of the receiving groove; When the cleaning component is in the extended state, the distal end of the cleaning component extends from the distal opening of the receiving groove; when the cleaning component is in the retracted state, the cleaning component is housed in the receiving groove. When the cleaning component is in the raised state, the cleaning component swings upward in the receiving groove and moves away from the cleaning working surface.

[0015] The above technical solution has the following beneficial effects: The cleaning device and sweeper provided by this utility model include a fixed bracket, a sliding bracket, a cleaning component, a sliding seat, a first elastic element, a second elastic element, and a drive component.

[0016] The first elastic element is used to drive the sliding bracket to move toward the distal side, thereby causing the cleaning component to extend.

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0022] like Figure 1-13 As shown, an embodiment of the present invention provides a cleaning device, including a fixed bracket 1 having a proximal stop 1a and a distal stop 1b, a sliding bracket 2 slidably mounted on one side of the fixed bracket 1, a cleaning component 3 hinged to one side of the sliding bracket 2 and having a hook 33, a first elastic member 4 connected to the sliding bracket 2 and used to drive the sliding bracket 2 to move toward the distal side so as to drive the cleaning component 3 to extend toward the distal side, and a driving component 5 capable of causing the sliding bracket 2 to move toward the proximal side so as to drive the cleaning component 3 to retract toward the proximal side.

[0023] The sliding bracket 2 is fixedly connected to the translation bracket 21, which is slidably mounted between the proximal stop 1a and the distal stop 1b.

[0024] A sliding seat 6 is slidably mounted on the translation bracket 21. The sliding seat 6 is provided with a wedge-shaped guide 61 for engaging with the hook 33 to drive the cleaning component 3 to swing upward.

[0025] A second elastic element 7 is connected between the sliding bracket 2 and the sliding seat 6 to drive the sliding seat 6 to move toward the distal side so that the wedge guide 61 separates from the hook 33.

[0026] The drive assembly 5 is connected to the sliding seat 6 and can drive the sliding seat 6 to move toward the proximal side so that the wedge guide 61 engages with the hook 33.

[0027] The cleaning device provided by this utility model is a component for sweeping and mopping the floor by a sweeper. According to the direction in which the sweeper travels, the cleaning device is generally installed in the rear half of the sweeper body.

[0028] The cleaning device provided by this utility model includes a fixed bracket 1, a sliding bracket 2, a cleaning component 3, a first elastic element 4, a driving component 5, a sliding seat 6, and a second elastic element 7.

[0029] In this invention, the cleaning component 3 can extend to one side to clean the edges and corners of the floor. The direction in which the cleaning component 3 extends is approximately perpendicular to the direction in which the sweeper travels. If the direction in which the sweeper travels is defined as forward, then the direction in which the cleaning component 3 extends can be to the left or right. For ease of description, in this invention, the direction or side in which the cleaning component 3 extends is referred to as the distal side, and the side opposite to the direction in which the cleaning component 3 extends is referred to as the proximal side. Correspondingly, the distal end of each component arranged approximately perpendicular to the front-back direction in the cleaning device is referred to as the distal end, and the other end is referred to as the proximal end.

[0030] The fixed bracket 1 is longitudinally elongated, combined with Figure 14-20 As shown, the fixed bracket 1 is installed on the bottom of the housing 9 of the sweeper and extends in the left-right direction or laterally. In the left-right direction, the fixed bracket 1 has a proximal stop 1a at its proximal end and a distal stop 1b at its distal end.

[0031] The sliding bracket 2 is also elongated and is used to assemble the cleaning component 3, enabling the cleaning component 3 to slide in the left-right direction. The sliding bracket 2 is mounted on one side of the fixed bracket 1, for example, the lower or rear side, and the sliding bracket 2 can slide relative to the fixed bracket 1 in the left-right direction. The sliding bracket 2 and the fixed bracket 1 can be connected by a linear guide structure to guide the sliding of the sliding bracket 2. In the left-right direction, the sliding bracket 2 has a proximal end 2a and a distal end 2b. The length of the sliding bracket 2 is longer than that of the fixed bracket 1 to accommodate a longer cleaning component 3.

[0032] A translation bracket 21 is fixedly provided at approximately the center position on one side of the sliding bracket 2. The translation bracket 21 is slidably connected to the fixed bracket 1 and can slide back and forth between the proximal stop 1a and the distal stop 1b.

[0033] The cleaning component 3 may employ a roller structure, comprising a proximal end 3a and a distal end 3b along the left-right direction. The cleaning component 3 includes a semi-open mop cover 31 and a mop roller 32 mounted within the mop cover 31. Both ends of the mop roller 32 are connected to the end plates of the mop cover 31 via rotating shafts and are equipped with motors to drive the mop roller 32 to rotate. The cleaning component 3 is not the inventive point of this invention; for details, please refer to existing descriptions of roller mops, which will not be elaborated upon here.

[0034] The cleaning component 3 is disposed on one side of the sliding bracket 2, specifically the front side. The mop cover 31, facing the sliding bracket 2, has a hook 33 for engaging with the wedge-shaped guide 61 (described later) to drive the cleaning component 3 to swing upwards. Preferably, the hook 33 is positioned diagonally above the mop cover 31 to match the height of the wedge-shaped guide 61 on the sliding seat 6 (described later).

[0035] The mop cover 31 has swing arms 34 extending toward the sliding bracket 2 at both ends. The sliding bracket 2 has mounting openings 23 at both ends facing the cleaning assembly 3, each containing a mounting shaft for mounting the swing arms 34 of the cleaning assembly 3. The swing arms 34 can swing up and down within the mounting openings 23, thereby causing the cleaning assembly 3 to swing up and down. If necessary, a torsion spring can be fitted between the mounting shaft and the swing arms 34 to press down on the swing arms 34, allowing the mop roller 32 of the cleaning assembly 3 to press firmly against the ground.

[0036] The first elastic element 4 can be either an elastic element or a spring. Its proximal end 4a is connected to the sliding bracket 2, and its distal end 4b is connected to the fixed bracket 1 or to the body of the sweeper. The first elastic element 4 provides a pulling force to the sliding bracket 2 to move distally, thereby driving the sliding bracket 2 to move distally relative to the fixed bracket 1, thereby causing the distal end 3b of the cleaning component 3 to extend from the distal side of the housing 9 to achieve the purpose of cleaning the corners of the floor.

[0037] The drive assembly 5 may be a motor drive assembly, which is connected to the sliding bracket 2 via a transmission connection, which may be a direct connection or an indirect connection, as long as the drive assembly 5 can cause the sliding bracket 2 to move toward the proximal side. When the drive assembly 5 is in the first working state, it provides a pulling force to the sliding bracket 2 to move toward the proximal side, overcoming the force of the first elastic element 4, so as to drive the cleaning assembly 3 to move toward the proximal side and retract into the housing 9.

[0038] The sliding seat 6 is mounted on the translation bracket 21 and can slide between the proximal and distal ends of the translation bracket 21. A wedge-shaped guide 61 is provided on the side of the sliding seat 6 facing the hook 33, and the two are adapted in the height direction. The wedge-shaped guide 61 has a guide ramp 611. Normally, the wedge-shaped guide 61 is located on the distal side of the hook 33. When the sliding seat 6 moves towards the proximal end on the translation bracket 21, the wedge-shaped guide 61 inserts into the hook 33. Due to the action of the guide ramp 611, the cleaning assembly 3 is driven to swing upwards, allowing the mop roller 32 to leave the ground.

[0039] The second elastic element 7 can be either an elastic element or a spring, with its proximal end 7a connected to the sliding seat 6 and its distal end 7b connected to the distal end 2b of the sliding bracket 2. The second elastic element 7 provides a pulling force to the sliding seat 6 toward the distal side, causing the sliding seat 6 to rest against the distal end of the translation bracket 21. The second elastic element 7 is used to drive the sliding seat 6 toward the distal side so that the wedge guide 61 separates from the hook 33.

[0040] The drive assembly 5 is connected to the sliding seat 6 via a transmission mechanism. The drive assembly 5 directly acts on the sliding seat 6, driving the sliding seat 6 to move proximally on the translation bracket 21, thereby engaging the wedge-shaped guide 61 with the hook 33, thus raising or lifting the cleaning assembly 3. When the drive assembly 5 is in the second working state, it provides a pulling force to the sliding seat 6 to move proximally, overcoming the force of the second elastic member 7, so that the sliding seat 6 moves proximally until it reaches the proximal end of the translation bracket 21.

[0041] Depending on the needs, the state in which the cleaning component is extended, retracted, or raised can be defined as the initial state. For ease of description, the state in which the cleaning component 3 is retracted and raised is defined as the initial state in this utility model.

[0042] In this invention, the first working state and the second working state of the drive assembly 5 are respectively used to overcome the forces of the first elastic element 4 and the second elastic element 7, and pull the corresponding component toward the near side. After the component moves to the correct position, the drive assembly 5 stops running and can keep the corresponding component in the corresponding position.

[0043] The drive assembly 5 can be connected to the sliding bracket 2 and the sliding seat 6 respectively through two sets of transmission mechanisms, or it can be connected to the sliding seat 6 only through one set of transmission mechanisms, and then drive the sliding bracket 2 to move toward the near side through the sliding seat 6 and the translation bracket 21.

[0044] The cleaning device provided by this utility model works as follows: In the initial state, the drive component 5 is in the initial state, the first elastic element 4 and the second elastic element 7 are both in the stretched state, and the cleaning component 3 is in the retracted and raised state.

[0045] When the cleaning device needs to clean the ground, the drive assembly 5 releases the pulling force on the sliding seat 6. Under the action of the second elastic element 7, the sliding seat 6 moves from the proximal end to the distal end on the translation bracket 21 until it slides to the distal end of the translation bracket 21. The wedge guide 61 leaves the hook 33, and the cleaning assembly 3 swings downward and presses on the ground under the action of gravity and / or torsion spring.

[0046] When the cleaning device needs to clean the corners of the floor, the drive assembly 5 releases the tension on the sliding bracket 2. Under the action of the first elastic element 4, the sliding bracket 2 moves towards the distal side until the translation bracket 21 slides to the distal end of the fixed bracket 1 and is blocked by the distal stop block 1b. During this process, the sliding bracket 2 drives the cleaning assembly 3 to move towards the distal side, so that the distal end of the cleaning assembly 3 extends beyond the distal side of the housing 9, thereby realizing the function of cleaning the corners of the floor.

[0047] When the cleaning component 3 needs to be retracted, the drive component 5 pulls the sliding bracket 2 to move towards the proximal side against the force of the first elastic element 4 until the translation bracket 21 slides to the proximal end of the fixed bracket 1 and is blocked by the proximal end stop 1a, indicating that the cleaning component 3 has retracted into place.

[0048] When the cleaning component 3 needs to be raised, the drive component 5 pulls the sliding seat 6 to move towards the proximal side against the force of the second elastic element 7 until the sliding seat 6 slides to the proximal end of the translation bracket 21, indicating that the wedge guide 61 is fully inserted into the hook 33, and the cleaning component 3 is raised to the maximum angle.

[0049] In this invention, the extension and lifting actions of the cleaning component 3 share a single drive component 5, which saves costs, facilitates installation, and helps reduce the size of the product.

[0050] In one embodiment, such as Figure 1-5 As shown, a mounting base 8 is configured at the bottom of the sliding bracket 2 to connect and fix it to the housing 9. The sliding bracket 2 is located above the mounting base 8 and can slide. The mounting base 8 is located on the rear side of the mop cover 31. The rear side of the mop cover 31 is provided with a long strip-shaped protrusion 34. The hook 33 can be provided on the protrusion 34. When the cleaning component 3 swings down to the limit position, the protrusion 34 falls on the mounting base 8, which plays a limiting role.

[0051] In one embodiment, such as Figure 1 , Figure 4-5 and Figure 7-11 As shown, the preset elastic force of the second elastic element 7 is greater than the preset elastic force of the first elastic element 4.

[0052] When the cleaning component 3 is in the extended state, the sliding seat 6 is located at the distal end of the translation bracket 21, which is blocked by the distal stop 1b.

[0053] When the cleaning component 3 is in the retracted state, the sliding seat 6 is at the distal end of the translation bracket 21, which is blocked by the proximal stop 1a.

[0054] When the cleaning component 3 is in the raised state, the sliding seat 6 is on the proximal side of the translation bracket 21, and the translation bracket 21 is blocked by the proximal stop 1a.

[0055] In this embodiment, by setting the preset elastic force of the second elastic element 7 to be greater than the preset elastic force of the first elastic element 4, the drive component 5 can be directly connected to the sliding seat 6 without being connected to the sliding bracket 2, which can save the transmission mechanism and facilitate the layout.

[0056] The preset elastic force of the elastic element includes the preload force when the elastic element is in its initial state and the tension force when the elastic element is stretched to its limit position.

[0057] When the translation bracket 21 is at the far end of the fixed bracket 1 and is blocked by the far end stop 1b, the first elastic element 4 is in the initial state, and the preload of the first elastic element 4 is F1. When the translation bracket 21 is at the near end of the fixed bracket 1 and is blocked by the near end stop 1a, the first elastic element 4 is in the tensile state, and the tension of the first elastic element 4 is F2.

[0058] When the sliding seat 6 is blocked at the far end of the translation bracket 21, the second elastic element 7 is in its initial state, and the preload of the second elastic element 7 is F3. When the sliding seat 6 is blocked at the near end of the translation bracket 21, the second elastic element 7 is in a stretched state, and the tension of the second elastic element 7 is F4.

[0059] Since the preset elastic force of the second elastic element 7 is greater than the preset elastic force of the first elastic element 4, F4 > F3 > F2 > F1.

[0060] Therefore, when the drive assembly 5 needs to pull the sliding bracket 2 proximally, a pulling force between F2 and F3 is applied to the sliding seat 6, which overcomes the first elastic element 4 without stretching the second elastic element 7. During this process, the force of the drive assembly 5 is transmitted to the sliding bracket 2 through the sliding seat 6 and the translation bracket 21. The sliding bracket 2 is pulled proximally until the translation bracket 21 moves to the proximal end of the fixed bracket 1 and is blocked by the proximal stop 1a, while the sliding seat 6 remains at the distal end of the translation bracket 21. At this time, the cleaning assembly 3 is in a fully retracted state and has not risen.

[0061] When the cleaning component 3 needs to be lifted off the ground, the drive component 5 applies a pulling force greater than F4 to the sliding seat 6, which can overcome the second elastic element 7, so that the sliding seat 6 slides from the far end to the near end of the translation bracket 21, thereby driving the wedge guide 61 to insert into the hook 33, so as to drive the cleaning component 3 to swing upward and rise.

[0062] In one embodiment, such as Figure 1-5 As shown, the drive assembly 5 includes a motor 51, a winch 52 connected to the output shaft of the motor 51, and a cable 53 connected to the winch 52.

[0063] The motor 51 is fixedly installed on the near side of the fixed bracket 1, and the cable 53 is connected to the sliding seat 6.

[0064] In this embodiment, the drive assembly 5 employs a motor drive mechanism, which includes a motor 51, a winch 52, and a cable 53. The motor 51 can be a servo motor or a stepper motor, and is fixedly mounted near the fixed bracket 1. The motor 51 can be mounted on the housing 9. The motor 51 can rotate in both directions. The winch 52 is used to wind the cable 53. The winch 52 is mounted on the output shaft of the motor 51 and can be driven to rotate in both directions, thereby enabling the contraction and release of the cable 53. The cable 53 can be a rope, wire rope, etc., and is connected to the sliding seat 6.

[0065] When the winch 52 is driven to rotate in the forward direction, it retracts the cable 53 and simultaneously pulls the sliding seat 6 against the force of the second elastic element 7, causing the sliding seat 6 to move towards the near side so that the wedge-shaped guide 61 can be inserted into the hook 33, causing the cleaning component 3 to swing upward and lift off the ground. When the winch 52 is driven to rotate in the reverse direction, it releases the cable 53, and under the action of the second elastic element 7, the sliding seat 6 moves towards the far side so that the wedge-shaped guide 61 can disengage from the hook 33, and the cleaning component 3 naturally swings down to the ground.

[0066] In one embodiment, such as Figure 1-5 , Figure 13 and Figure 15 As shown, the sliding seat 6 is provided with a guide wheel 62, the cable 53 is turned by the guide wheel 62, and the end 531 of the cable 53 is fixed to one side of the near end block 1a.

[0067] In this embodiment, a guide wheel 62 is provided on the sliding seat 6 for guiding the cable 53. The end of the cable 53 is fixed to one side of the near-end stop 1a and can be fixed to the housing 9. With this arrangement, the guide wheel 62 serves both as a guide and as a fixed pulley, which can speed up the movement of the sliding seat 6.

[0068] In one embodiment, such as Figure 1-7 , Figure 9 , Figure 11 and Figure 13 As shown, the fixed bracket 1 includes a first guide rod 11, which is connected between the proximal stop 1a and the distal stop 1b.

[0069] The translation bracket 21 is slidably connected to the first guide rod 11. In this embodiment, the fixed bracket 1 mainly consists of a proximal stop 1a, several first guide rods 11, and a distal stop 1b. The first guide rods 11 are connected between the proximal stop 1a and the distal stop 1b.

[0070] The translation bracket 21 has a first through hole corresponding to the position of the first guide rod 11. The first guide rod 11 passes through the first through hole, and the translation bracket 21 can slide along the first guide rod 11.

[0071] Preferably, the fixed bracket 1 includes two horizontally spaced first guide rods 11, and the translation bracket 21 is provided with two horizontally spaced first through holes. The two first guide rods 11 pass through the two first through holes respectively to stably support the translation bracket 21.

[0072] In one embodiment, the sliding seat 6 is slidably connected to the first guide rod 11 to improve the sliding stability of the sliding seat 6. The sliding seat 6 is provided with a second through hole 64 corresponding to the position of the first guide rod 11. The first guide rod 11 passes through the second through hole 64, and the sliding seat 6 can slide along the first guide rod 11.

[0073] Preferably, the sliding seat 6 is provided with two horizontally spaced second through holes 64, and two first guide rods 11 pass through the two second through holes 64 respectively to stably support the sliding seat 6.

[0074] In one embodiment, such as Figure 1-7 , Figure 9 , Figure 11 and Figure 13 As shown, the translation support 21 includes a proximal baffle 21a, a distal baffle 21b, and a second guide rod 211 connecting the proximal baffle 21a and the distal baffle 21b.

[0075] The proximal baffle 21a and the distal baffle 21b are respectively connected to the sliding bracket 2, and the sliding seat 6 is slidably connected to the second guide rod 211.

[0076] In this embodiment, the translation support 21 mainly consists of a proximal baffle 21a, a second guide rod 211, and a distal baffle 21b. The second guide rod 211 connects the proximal baffle 21a and the distal baffle 21b.

[0077] The proximal baffle 21a and the distal baffle 21b are respectively connected to the sliding bracket 2 to achieve integrated sliding. The sliding seat 6 is provided with a third through hole 65, through which the second guide rod 211 passes, allowing the sliding seat 6 to slide along the second guide rod 211 to improve the sliding stability of the sliding seat 6.

[0078] In one embodiment, such as Figure 1-13 As shown, the sliding bracket 2 is located at the bottom of the fixed bracket 1, and the translation bracket 21 is located at the top of the sliding bracket 2.

[0079] The base plate of the sliding bracket 2 is provided with an opening 22 for avoiding the sliding seat 6, and the lower end 63 of the sliding seat 6 passes downward through the opening 22.

[0080] The second elastic element 7 is connected to the bottom of the sliding bracket 2. One end of the second elastic element 7 is connected to the far end 2b of the sliding bracket 2, and the other end of the second elastic element 7 is connected to the lower end 63 of the sliding seat 6.

[0081] In this embodiment, in order to save installation space, the sliding bracket 2 is arranged at the bottom of the fixed bracket 1, and the translation bracket 21 is fixedly arranged at the top of the sliding bracket 2 to be slidably connected with the fixed bracket 1.

[0082] The second elastic element 7 is disposed at the bottom of the sliding bracket 2. To facilitate the connection between the sliding seat 6 and the second elastic element 7, an opening 22 is provided in the bottom plate of the sliding bracket 2 to avoid the lower end 63 of the sliding seat 6. The lower end 63 of the sliding seat 6 passes downward through the opening 22 to connect with the proximal end 7a of the second elastic element 7, and the distal end 7b of the second elastic element 7 connects with the distal end 2b of the sliding bracket 2.

[0083] In one embodiment, the wedge-shaped guide 61 is integrally connected with the sliding seat 6, which facilitates processing and forming, has high structural strength, and a long service life.

[0084] In one embodiment, such as Figure 6-7 , Figure 9 , Figure 11 and Figure 13 As shown, the thickness of the wedge-shaped guide 61 gradually increases along the direction from the proximal side to the distal side. The guide ramp 611 at the top of the wedge-shaped guide 61 gradually extends upwards along the direction from the proximal side to the distal side. When the wedge-shaped guide 61 moves from the distal side to the proximal side and is inserted into the hook 33, the hook 33 is driven to swing upwards by the action of the guide ramp 611.

[0085] like Figure 14-20 As shown, an embodiment of the present invention provides a sweeping machine, including a housing 9 and the cleaning device described in any of the foregoing embodiments.

[0086] The drive assembly 5 is connected to the housing 9. The bottom surface of the housing 9 is provided with a receiving groove 91, and the cleaning assembly 3 is movably assembled in the receiving groove 91.

[0087] The fixed bracket 1 is installed on the bottom surface of the housing 9 and is located on one side of the receiving groove 91.

[0088] When the cleaning component 3 is in the extended state, its distal end extends from the distal opening 91b of the receiving groove 91. When the cleaning component 3 is in the retracted state, it is housed within the receiving groove 91.

[0089] When the cleaning component 3 is in the raised state, the cleaning component 3 swings upward in the receiving groove 91 and moves away from the cleaning working surface.

[0090] The sweeper provided by this utility model includes a housing 9 and a cleaning device. For the structure, construction and working principle of the cleaning device, please refer to the previous description of the cleaning device, which will not be repeated here.

[0091] The housing 9 is part of the sweeper housing. The bottom of the housing 9 is provided with a receiving groove 91 for installing the cleaning component 3. The bottom slot of the receiving groove 91 is used for the cleaning component 3 to swing downward to land and swing upward to retract. The distal slot 91b of the receiving groove 91 is used for the distal end 3b of the cleaning component 3 to extend out.

[0092] As needed, mounting holes 94 can be provided on the housing 9 at positions corresponding to the proximal stop 1a and the distal stop 1b. The fixing bracket 1 is installed at the bottom of the housing 9 and is located behind the receiving groove 91. Screws 24 are used to pass downward through the mounting holes 94 to fix the proximal stop 1a and the distal stop 1b to the bottom of the housing 9.

[0093] If necessary, an opening 92 may be provided on the top surface of the housing 9, and the opening 92 is located to avoid the sliding support 21 and sliding seat 6, etc.

[0094] If necessary, a motor mounting slot 93 can be provided on the top surface of the housing 9 for mounting the motor 51.

[0095] When the drive assembly 5 does not act on the sliding bracket 2, under the action of the first elastic member 4, when the cleaning assembly 3 is in the extended state, the distal end 3b of the cleaning assembly 3 extends from the distal opening 91b of the receiving groove 91 for cleaning the corners of the floor. Under the action of the drive assembly 5, the cleaning assembly 3 moves proximally and retracts into the receiving groove 91, where it is housed.

[0096] When the cleaning component 3 is in the extended or retracted state, the bottom of the roller mop 32 of the cleaning component 3 extends from the bottom slot of the receiving groove 91 for cleaning the floor or ground surface, which is also referred to as the cleaning work surface.

[0097] After the drive assembly 5 drives the sliding seat 6 to move closer to the side, the wedge guide 61 and the hook 33 cooperate to make the cleaning assembly 3 swing upward in the receiving groove 91. At this time, the roller mop 32 of the cleaning assembly 3 moves away from the cleaning work surface and the roller mop 32 of the cleaning assembly 3 is off the ground.

[0098] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0099] The above are merely the principles and preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of this utility model, and these modifications should also be considered within the scope of protection of this utility model.
