[0002] Among the current automatic cleaning equipment, mops and sweepers are widely popular because of their mopping function. After completing a certain cleaning task or cleaning for a specified time, the base station can stop at the base station to clean the rag and reuse it. One rag is used for uniform cleaning in all scenes, and it is impossible to automatically change the rag for targeted cleaning in different scenes. In addition, oil stains are easy to remain in the rag during the cleaning process, and returning to the base station for cleaning cannot completely eliminate the oil stains. When the base station performs the cleaning task again, it is easy to cause secondary pollution to the cleaning surface.

[0101] In the following detailed disclosure, these embodiments are fully described with reference to the accompanying drawings. In order to make the technical scheme of the present invention more clear and specific to those skilled in the art, the implementation methods described below are not limited to this. The present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings.

[0102] The first aspect of the present invention, as Figure 1-Figure 18 , provides a cleaning element replacement device, which is applied to an automatic cleaning system. The automatic cleaning system includes a base station 200, and the cleaning element replacement device includes a transmission device 100 and a drive component 4. The transmission device 100 is used to connect with the cleaning element 110, and the output end of the drive component 4 is connected to the transmission device 100. The drive component 4 drives the cleaning element 110 to move through the transmission device 100 so that the cleaning element 110 enters or moves out of the base station 200.

[0103] The cleaning element replacement device includes a transmission device 100 and a driving assembly 4. The driving assembly 4 drives the cleaning element 110 to move through the transmission device 100, so that the cleaning element 110 can automatically switch positions inside and outside the base station 200. When the cleaning element 110 is idle, it is moved outside the base station 200 for drying and reducing bacterial growth; when in use, the cleaning element 110 is moved into the base station 200, which is convenient for subsequent replacement of the cleaning element 110 of the automatic cleaning device, saving time and effort.

[0104] The cleaning element 110 can be automatically replaced by the cleaning element replacement device, thereby increasing the replacement frequency of the cleaning element 110, reducing residual stains on the cleaning element 110, improving the cleanliness of the cleaning element 110, and reducing secondary contamination of the surface to be cleaned. After the automatic cleaning device leaves the base station 200, the idle cleaning element 110 can be moved to the accommodating chamber 220 for cleaning. After the automatic cleaning device returns to the base station 200, the cleaning element 110 can be directly replaced, thereby reducing the time for returning to the base station 200 to clean the cleaning element 110 after performing the cleaning task, thereby improving work efficiency and user satisfaction.

[0105] It is also possible to perform targeted cleaning for different scenes by replacing the cleaning elements 110 with different materials, which greatly improves the cleaning effect. The device has a small space occupancy rate and can realize multiple functions such as lifting and rotating through the linkage of multiple transmission components, including driving the cleaning element 110 to move longitudinally, laterally, and lift and lower, which greatly reduces the power module, simplifies the structure of the base station 200, and reduces the cost.

[0106] In one possible implementation, Fig.17 and Fig.18 As shown, the base station 200 also includes a accommodating cavity 220, which is used to accommodate the cleaning element 110. The moving path of the cleaning element 110 includes a first operating position located inside the accommodating cavity 220 and a second operating position located outside the accommodating cavity 220. The transmission device 100 drives the cleaning element 110 to switch between the first operating position and the second operating position.

[0107] It is understandable that the base station 200 is provided with a receiving chamber 220, which can receive the cleaning element 110 and clean the cleaning element 110 to remove dirt on the cleaning element 110, so that the cleaning element 110 can be reused after cleaning.

[0108] The present application drives the transmission device 100 through the driving component 4 to drive the cleaning element 110 to move, and drives the cleaning element 110 to switch between two operating positions inside the accommodating chamber 220 and outside the accommodating chamber 220. When the cleaning element 110 is placed in the first operating position inside the accommodating chamber 220, when a cleaning device is provided in the accommodating chamber 220, the cleaning device may include a wiper, a flushing device, etc., which can clean the cleaning element 110 in the accommodating chamber 220, so as to facilitate the replacement of the cleaning element 110 after the automatic cleaning device returns to the base station 200; compared with the situation in which the cleaning element 110 is always placed in the accommodating chamber 220 after the traditional automatic cleaning device returns to the base station 200, the present application places the cleaning element 110 in the second operating position outside the accommodating chamber 220, so that the cleaning element 110 is exposed to the external environment, which is convenient for the cleaning element 110 to dry, reduce bacterial growth, and reduce the generation of odor by the cleaning element 110.

[0109] In one possible implementation, Figure 1-Figure 8 As shown, the transmission device 100 includes a first transmission assembly 1, and the driving assembly 4 includes a first driving part 41. The first driving part 41 is connected to the first transmission assembly 1 to drive the cleaning element 110 to move, so that the cleaning element 110 can enter or move out of the accommodating chamber 220.

[0110] like Figure 7 As shown, the first driving part 41 includes a first motor 411 and a first reduction mechanism 412 . The first reduction mechanism 412 includes a first gear set and a first parallel shaft reducer connected to each other. The first motor 411 is connected to the first gear set, and the first parallel shaft reducer is connected to the rotating member 11 .

[0111] It can be understood that the first driving portion 41 drives the cleaning element 110 to move through the first transmission assembly 1 , and a portion of the moving path of the cleaning element 110 is located inside the accommodating cavity 220 , and another portion is located outside the accommodating cavity 220 .

[0112] In one possible implementation, Figure 7-Figure 9 As shown, the first transmission assembly 1 includes a rotating member 11, a connecting member 12 and a guide member 13. The output end of the first driving part 41 is connected to the rotating member 11, and the connecting member 12 is connected to the cleaning element 110. The first driving part 41 drives the connecting member 12 to move through the rotating member 11. A track groove 131 is provided on the guide member 13 to limit the connecting member 12 from moving along the direction of the track groove 131.

[0113] It can be understood that the first driving part 41 is connected to the rotating member 11 and drives the rotating member 11 to rotate along its own axis. A part of the connecting member 12 is sleeved on the rotating member 11, and the rotation of the rotating member 11 drives the connecting member 12 to move synchronously. The other part of the connecting member 12 is inserted into the track groove 131, so that the connecting member 12 can move along the track groove 131 during the movement of the rotating member 11, so as to drive the cleaning element 110 to move along the preset moving path.

[0114] It is understandable that the guide member 13 can be a hollow cylinder, and the guide member 13 is sleeved on the outer peripheral side of the rotating member 11. The guide member 13 can also be other shapes such as arc surface, square, etc., as long as it can meet the load-bearing track groove 131.

[0115] Among them, Fig.10 and Fig.11 As shown, the rotating member 11 includes a screw 111, and the connecting member 12 includes a sleeve 121 and a rod body 122. The sleeve 121 is threadedly sleeved on the screw 111, and the rod body 122 is inserted into the track groove 131. The first driving part 41 drives the screw 111 to rotate and drives the sleeve 121 to move along the screw 111, so that the rod body 122 moves along the track groove 131.

[0116] It is understandable that if Fig.10 As shown, the first motor 411 drives the screw 111 to rotate through the first reduction mechanism 412, and the screw 111 and the sleeve 121 rotate relative to each other, so that the rotational motion of the screw 111 is converted into the linear motion of the sleeve 121. Through the setting of the track groove 131, the sleeve 121 can also rotate along the track groove 131 during the lifting process. The setting of the screw 111 and the sleeve 121 greatly reduces the friction of the transmission, reduces the friction loss, extends the service life of the transmission device 100, improves the flexibility of the movement of the connecting member 12, has high precision, and can meet the precision requirements of the moving path of the cleaning element 110. At the same time, it also reduces the driving power required by the first driving part 41, improves the transmission efficiency, and greatly reduces the occupancy rate of the horizontal space, which is simpler and low in cost.

[0117] It is understandable that if Figure 11-Figure 14 As shown, the sleeve 121 is connected to the rod body 122, the sleeve 121 is located on one side of the track groove 131, the rod body 122 is inserted into the track groove 131 and finally connected to the cleaning element 110. During the movement of the sleeve 121 along the screw 111, the rod body 122 is driven to move along the track groove 131, thereby driving the cleaning element 110 to move along a preset path.

[0118] In one possible implementation, Figure 11-Figure 14As shown, the connecting member 12 further includes a baffle 123 , which is disposed on the rod body 122 , and the track groove 131 is located between the sleeve 121 and the baffle 123 , and the width of the baffle 123 is greater than the groove width of the track groove 131 .

[0119] like Fig.14 As shown, the sleeve 121 is arranged at one end of the rod body 122, and the baffle 123 is arranged on the rod body 122. The sleeve 121 and the baffle 123 are respectively located on both sides of the track groove 131. The setting of the baffle 123 can ensure the axial clearance between the screw 111 and the sleeve 121, improve the stability of the transmission, reduce the swing and vibration of the connecting part 12, make the movement process of the cleaning element 110 more stable, and ensure the movement accuracy.

[0120] In one possible implementation, Fig.11 As shown, the track groove 131 includes a first lifting section 1311 and a rotating section 1312. The first lifting section 1311 is arranged along a first direction, and the connecting member 12 moves along the first lifting section 1311 to drive the cleaning element 110 to rise or fall; the rotating section 1312 is arranged along a second direction, and the connecting member 12 moves along the rotating section 1312 to drive the cleaning element 110 to rotate into or move out of the accommodating chamber 220; the first direction is different from the second direction.

[0121] It can be understood that the trajectory groove 131 can be formed by connecting the first lifting section 1311 and the rotating section 1312, or it can only include the rotating section 1312. By setting the first lifting section 1311 along the first direction and the rotating section 1312 along the second direction, the connecting member 12 can move along the trajectory groove 131 to drive the cleaning element 110 to lift and / or rotate.

[0122] The first direction is a non-horizontal direction, which may be the axial direction of the rotating member 11 , that is, the vertical direction; the second direction is a non-vertical direction, which may be the circumferential direction along the rotating member 11 .

[0123] Among them, the first lifting section 1311 is configured to enable the cleaning element 110 to move along the axial direction of the rotating member 11, that is, to move in the longitudinal direction, so as to achieve the effect of lifting and lowering the cleaning element 110 in the accommodating chamber 220, making it easier for the cleaning element 110 to reach the designated position of the accommodating chamber 220 and reducing the obstruction of the cleaning element 110 by the wall of the accommodating chamber 220 of the base station 200 when moving out.

[0124] The rotating section 1312 is arranged to make the cleaning element 110 rotate along the circumference of the rotating member 11 , that is, move in the horizontal direction, so that the cleaning element 110 enters or moves out of the accommodating cavity 220 .

[0125] This embodiment takes the rotating section 1312 as an example. Fig.11As shown, one end of the rotating section 1312 is higher than the other end of the rotating section 1312 . When the connecting member 12 moves along the rotating section 1312 , the cleaning element 110 is driven to rotate upward or downward around the rotating member 11 as the axis.

[0126] When the connecting member 12 moves along the rotating section 1312 , the connecting member 12 moves both axially and circumferentially, so as to drive the cleaning element 110 to move up and down and rotate around the rotating member 11 as the axis.

[0127] This embodiment takes the rotating section 1312 being arranged horizontally as an example. The rotating section 1312 is arranged horizontally. During the movement of the connecting member 12 along the rotating section 1312 , the cleaning element 110 is driven to rotate in a horizontal direction with the rotating member 11 as the axis.

[0128] When the connecting member 12 moves along the rotating section 1312 , the connecting member 12 moves in the circumferential direction, thereby driving the cleaning element 110 to rotate around the rotating member 11 as the axis.

[0129] In one possible implementation, Fig.11 As shown, the track groove 131 further includes a second lifting section 1313 , which is arranged along the first direction. When the connecting member 12 moves along the second lifting section 1313 , the cleaning element 110 is driven to rise or fall.

[0130] It can be understood that the trajectory groove 131 can include only the rotating section 1312, or it can be composed of the first lifting section 1311 and the rotating section 1312, or it can be composed of the first lifting section 1311, the rotating section 1312 and the second lifting section 1313, and the rotating section is located between the first lifting section 1311 and the second lifting section 1313, so that the connecting member 12 moves along the trajectory groove 131 to drive the cleaning element 110 to rise and fall and / or rotate.

[0131] Among them, the second lifting section 1313 is configured to enable the cleaning element 110 to move along the axial direction of the rotating part 11, that is, to move in the longitudinal direction, so as to achieve the effect of lifting and lowering the cleaning element 110 in the accommodating chamber 220, so as to facilitate the adjustment of the height of the cleaning element 110 after the cleaning element 110 is moved out of the accommodating chamber 220, so as to avoid obstruction to the automatic cleaning equipment to and from the base station 200, and to reduce the occupied space.

[0132] In one possible implementation, Figure 7 As shown, the cleaning element 110 is hinged to the connecting member 12 via a hinge 27, and the transmission device 100 also includes a second transmission component 2, which is connected to the first transmission component 1, and the second transmission component 2 is connected to the hinge 27 to drive the cleaning element 110 to move along a third direction; the third direction is different from both the first direction and the second direction.

[0133] It can be understood that the first transmission component 1 drives the cleaning element 110 to achieve lifting and / or rotation. The cleaning element 110 can rotate relative to the connecting member 12 through the hinge 27, that is, it can rotate relative to the first transmission component 1. The second transmission component 2 is connected to the cleaning element 110 through the hinge 27, driving the hinge 27 to deform to lift or lower the cleaning element 110.

[0134] The third direction may be an arc direction, with the hinge 27 as the arc center and the distance between the hinge 27 and the cleaning element 110 as the arc radius. The third direction may be located in a vertical plane.

[0135] In one possible implementation, Figure 6 and 7 As shown, the transmission device 100 also includes a fixed seat 5, the first driving part 41 is arranged on the fixed seat 5, the second transmission assembly 2 includes a first shell 21 and a second shell 22, the first shell 21 is connected to the fixed seat 5; the second shell 22 is movably connected to the first shell 21, and the connecting member 12 is connected to the first shell 21 or the second shell 22; during the movement of the connecting member 12 along the second lifting section 1313, the connecting member 12 is connected to the second shell 22 to drive the second shell 22 to move, so that the hinge 27 is deformed to drive the cleaning element 110 to move.

[0136] It is understandable that if Figure 7 As shown, the fixed seat 5 may include a base and a connecting seat, the base is used to accommodate the first driving part 41, the first driving part 41 is connected to the first transmission assembly 1, and the connecting seat is connected to the second transmission assembly 2, that is, the connecting seat is connected to the first shell 21, and the first driving part 41 drives the cleaning element 110 to lift and / or rotate through the first transmission assembly 1.

[0137] When the cleaning element 110 rotates, the second rotating assembly rotates with the cleaning element 110, that is, the fixed seat 5 is rotationally connected with the first shell 21. When the track groove 131 includes the second lifting section 1313, when the connecting member 12 rises along the second lifting section 1313, the connecting member 12 moves upward to drive the second shell 22 to move away from the cleaning element 110, so that the hinge 27 is deformed, and then drives the cleaning element 110 to move to achieve the lifting action; when the connecting member 12 descends along the second lifting section 1313, the connecting member 12 moves downward to drive the second shell 22 to move toward the cleaning element 110, so that the hinge 27 returns to its original position, and then drives the cleaning element 110 to move to achieve the descending action.

[0138] In one possible implementation, Figure 6As shown, the hinge 27 includes a first hinge unit and a second hinge unit, a first hinge point 271 is formed between the first hinge unit and the second hinge unit, the connecting member 12 is connected to the first hinge unit, and the cleaning element 110 is connected to the second hinge unit.

[0139] It can be understood that the connecting member 12 and the cleaning element 110 are arranged at both ends of the first hinge point 271, so that the hinge 27 can be bent at the first hinge point 271, and then the cleaning element 110 can rotate relative to the connecting member 12. The connecting member 12 is connected to the first hinge unit, and the second transmission assembly 2 is connected to the second hinge unit.

[0140] In one possible implementation, Figure 6 As shown, a first slide rail 211 is provided on the first shell 21, a second slide rail 221 is provided on the second shell 22, the second transmission assembly 2 includes a lifting slider 243 and a connecting frame 244, the lifting slider 243 is connected to the first slide rail 211 or the second slide rail 221, the lifting slider 243 is connected to the second hinge unit through the connecting frame 244, and a second hinge point 272 is formed between the connecting frame 244 and the second hinge unit.

[0141] The lifting slider 243 can slide on the first slide rail 211 or the second slide rail 221. When the first transmission assembly 1 drives the cleaning element 110 to move through the connecting member 12, the connecting frame 244 is connected to the connecting member 12 through the hinge 27 and moves synchronously therewith, thereby driving the lifting slider 243 to slide synchronously on the first slide rail 211 or the second slide rail 221.

[0142] When the connecting member 12 moves along the first lifting section 1311 and the rotating section 1312, the lifting slider 243 slides on the first slide rail 211, and the first slide rail 211 is aligned with the second slide rail 221; when the connecting member 12 enters the second lifting section 1313 along the rotating section 1312, the lifting slider 243 enters the second slide rail 221 along the first slide rail 211, and the connecting member 12 rises to drive the second shell 22 to move. At this time, the first slide rail 211 and the second slide rail 221 are misaligned, and the second shell 22 moves away from the cleaning element 110. The connecting member 12 moves toward and drives the connecting frame 244 to move, and drives the cleaning element 110 to be lifted through the connecting frame 244; when the connecting member 12 enters the rotating section 1312 along the second lifting section 1313, the connecting member 12 descends and drives the second shell 22 to reset, the first slide rail 211 and the second slide rail 221 are aligned, and the lifting slider 243 enters the first slide rail 211 along the second slide rail 221, and the second shell 22 moves toward the direction close to the cleaning element 110 and drives the connecting frame 244 to move, and drives the cleaning element 110 to descend through the connecting frame 244.

[0143] Among them, the first slide rail 211 can be two, which are respectively arranged on the outer wall of the first shell 21, and the second slide rail 221 can be two corresponding ones, which are respectively arranged on the outer wall of the second shell 22. When the connecting member 12 is located in the first lifting section 1311 and the rotating section 1312, the first slide rail 211 and the second slide rail 221 are aligned so that the lifting slider 243 can switch between the first slide rail 211 and the second slide rail 221.

[0144] like Fig.13 As shown, the second hinge point 272 and the connection between the cleaning element 110 and the hinge 27 are all located on the same side of the first hinge point 271, that is, on the side of the first hinge point 271 away from the connecting member 12. The second transmission assembly 2 drives the second hinge unit to move through the lifting slider 243 and the connecting frame 244, thereby driving the cleaning element 110 to move.

[0145] In one possible implementation, Figure 2 As shown, the second transmission assembly 2 further includes a rotation connection assembly 26 , and the first housing 21 is rotationally connected to the fixing seat 5 via the rotation connection assembly 26 .

[0146] like Figure 7 and Figure 8 As shown, when the connecting member 12 moves along the rotating section 1312 , the first housing 21 is driven to rotate. By setting a rotating connecting assembly 26 between the first housing 21 and the fixing seat 5 , the first housing 21 can rotate relative to the fixing seat 5 .

[0147] Among them, Figure 4 As shown, the rotating connection component 26 also includes a first slide groove 261 and a first limit member 262. The first slide groove 261 is an arc groove. The first slide groove 261 and the first limit member 262 are correspondingly arranged. The first limit member 262 and the first slide groove 261 can move relative to each other, thereby limiting the moving direction of the second transmission component 2.

[0148] It can be understood that the first slide groove 261 is arranged on the first housing 21, and the first stopper 262 is arranged on the fixing seat 5; or, the first slide groove 261 is arranged on the fixing seat 5, and the first stopper 262 is arranged on the first housing 21. The first stopper 262 is inserted into the arc-shaped first slide groove 261, and the arc center of the first slide groove 261 is located on the axis of the rotating member 11. The first stopper 262 and the first slide groove 261 can move relative to each other, so that the first housing 21 can slide along the setting direction of the first slide groove 261, and the moving direction of the second transmission assembly 2 is limited, so that the second transmission assembly 2 can rotate synchronously with the cleaning element 110.

[0149] In one possible implementation, Figure 4As shown, the second transmission assembly 2 further includes a sliding connection assembly 24 , and the first housing 21 is movably connected to the first housing 21 via the sliding connection assembly 24 .

[0150] When the connecting member 12 moves along the second lifting section 1313 , the second housing 22 is driven to move. A sliding connection assembly 24 is provided between the first housing 21 and the second housing 22 so that the second housing 22 can slide relative to the first housing 21 .

[0151] Among them, Fig.15 and Fig.16 As shown, the sliding connection assembly 24 includes a second slide groove 241 and a second limit member 242. The second slide groove 241 is a linear groove. The second slide groove 241 and the second limit member 242 are correspondingly arranged. The second limit member 242 and the second slide groove 241 can move relative to each other to limit the moving direction of the second shell 22.

[0152] It can be understood that the second slide groove 241 is arranged on the first shell 21, and the second stopper 242 is arranged on the second shell 22; or, the second slide groove 241 is arranged on the second shell 22, and the second stopper 242 is arranged on the first shell 21. The second stopper 242 is inserted into the linear second slide groove 241, and the second slide groove 241 can be located in the horizontal direction and extend along the cleaning element 110 toward the rotating member 11. The second stopper 242 and the second slide groove 241 can move relative to each other, so that the second shell 22 can slide along the setting direction of the second slide groove 241, and the moving direction of the second shell 22 is limited, so that the second shell 22 can move synchronously with the connecting member 12 and drive the cleaning element 110 to move.

[0153] In one possible implementation, Figure 7-10 As shown, the second transmission assembly 2 also includes a lifting slider 23, which is arranged between the connecting member 12 and the second shell 22; during the movement of the connecting member 12 along the second lifting section 1313, the connecting member 12 abuts against the lifting slider 23 and drives the lifting slider 23 to move along the first direction, so that the lifting slider 23 abuts against the second shell 22 and drives the second shell 22 to move away from the cleaning element 110.

[0154] It can be understood that a lifting slider 23 is provided between the connecting member 12 and the second shell 22. When the connecting member 12 moves in the first lifting section 1311 or the rotating section 1312, the connecting member 12 has no contact with the lifting slider 23. The lifting slider 23 can be in contact with the second shell 22 or can be separated from the second shell 22. At this time, the lifting slider 23 does not apply force to the second shell 22, and the second shell 22 does not shift.

[0155] It is understandable that if Fig.15 and Fig.16 As shown, when the connecting member 12 ascends in the second lifting section 1313, the connecting member 12 abuts against the lifting slider 23 and drives the lifting slider 23 to move upward, and the lifting slider 23 abuts against the second shell 22 and applies a thrust to the second shell 22 to make it move along the second slide groove 241, so that the second shell 22 moves away from the cleaning element 110; when the connecting member 12 descends in the second lifting section 1313, the lifting slider 23 descends in height, and the second shell 22 moves toward the cleaning element 110 until it returns to its original position.

[0156] Among them, Fig.15 and Fig.16 As shown, the second shell 22 includes a slope 222 , and the lifting slider 23 includes a matching surface 231 matched with the slope 222 , and the matching surface 231 abuts against the slope 222 to cooperate with the lifting slider 23 to drive the second shell 22 to move.

[0157] The shape of the mating surface 231 can be a slope, and the slope of the mating surface 231 can be consistent with the slope 222. When the lifting slider 23 abuts against the second shell 22, the mating surface 231 fits with the slope 222, so that the second shell 22 moves more smoothly. The shape of the mating surface 231 can also be an arc surface or other shapes.

[0158] The lifting slider 23 is movably connected to the guide member 13. Figure 7-Figure 9 As shown, the outer circumference of the lifting slider 23 may be provided with a protrusion structure and / or a groove structure, and the inner circumference of the guide member 13 is adapted to the outer circumference of the lifting slider 23 to form a limit in the horizontal rotation direction of the lifting slider 23. The lifting slider 23 can only move in the first direction and cannot rotate in the horizontal direction, and the matching surface 231 and the slope surface 222 are always kept opposite during the movement of the lifting slider 23.

[0159] like Fig.10 As shown, in this embodiment, the lifting slider 23 is sleeved on one end of the rotating member 11 as an example. The lifting slider 23 is separated from the rotating member 11 and does not rotate with the rotating member 11. The lifting slider 23 abuts against the guide member 13. The connecting member 12 moves upward and abuts against the lifting slider 23, driving the lifting slider 23 to move.

[0160] Among them, Fig. 9 As shown, the lifting slider 23 may further include a flange 232, which is disposed on the lifting slider 23 and is used to abut against the guide member 13 to limit the lifting slider 23 in the first direction.

[0161] In one possible implementation, Figure 4As shown, the second transmission assembly 2 also includes a reset assembly 25, which is arranged between the first shell 21 and the second shell 22; when the connecting member 12 moves out of the second lifting section 1313, the reset assembly 25 drives the second shell 22 to move towards the cleaning element 110.

[0162] When the connecting member 12 moves along the second lifting section 1313, the second housing 22 is driven to move, and the second housing 22 slides relative to the first housing 21 through the sliding connection assembly 24. A reset assembly 25 is arranged between the first housing 21 and the second housing 22. When the connecting member 12 descends in the second lifting section 1313, the second housing 22 abuts against the lifting slider 23 under the action of the reset assembly 25. The lifting slider 23 descends under the push of the second housing 22 and the action of its own weight, and the second housing 22 moves toward the direction close to the cleaning element 110 until it returns to its original position.

[0163] Among them, Fig.15 and Fig.16 As shown, the reset assembly 25 also includes a reset link 251 and an elastic member 252. One end of the reset link 251 is connected to the first shell 21 or the second shell 22, and extends along the moving direction of the second shell 22 relative to the first shell 21; the elastic member 252 is sleeved on the reset link 251, the first end of the elastic member 252 is relatively fixed to the position of the first shell 21, and the second end of the elastic member 252 is relatively fixed to the position of the second shell 22.

[0164] It can be understood that the direction of relative movement between the second slide groove 241 and the second stopper 242 is consistent with the deformation direction of the reset assembly 25, so that after the second slide groove 241 and the second stopper 242 move relative to each other, the reset assembly 25 can apply a force to restore the second slide groove 241 and the second stopper 242 to their original positions, so as to drive the second slide groove 241 and the second stopper 242 to reset. The elastic member 252 can be sleeved on the reset link 251, and the reset link 251 is used to limit the deformation direction of the elastic member 252.

[0165] The elastic member 252 may be a tension spring, a first end of the tension spring is connected to the first shell 21 , and a second end of the tension spring is connected to the second shell 22 .

[0166] The elastic member 252 may be a compression spring, a first end of the compression spring is relatively fixed to the first housing 21 , and a second end of the compression spring is relatively fixed to the second housing 22 .

[0167] The elastic member 252 may be an elastic sheet, a first end of the tension spring is connected to the first shell 21 , and a second end of the tension spring is connected to the second shell 22 .

[0168] In one embodiment, the cleaning element 110 and the transmission device 100 are detachably connected, and the cleaning element 110 is driven by the transmission device 100 to move its position so as to switch between the inside and outside of the accommodating chamber 220 of the base station 200. In a specific implementation, when the transmission device 100 moves the cleaning element 110 into the accommodating chamber 220, the cleaning element 110 can be cleaned while the cleaning element 110 and the transmission device 100 remain connected, or the cleaning element 110 can be separated from the transmission device 100 so that the cleaning element 110 is separated from the transmission device 100 and placed in the accommodating chamber 220, so as to facilitate the subsequent assembly of the automatic cleaning equipment and the cleaning element 110.

[0169] Among them, the cleaning element 110 and the transmission device 100 may be at least one of a magnetic structure, a threaded structure, a clamping structure, and a mortise and tenon structure, so as to realize that the transmission device 100 and the cleaning element 110 are detachable.

[0170] In this embodiment, a magnetic attraction structure is used between the cleaning element 110 and the transmission device 100 as an example. By providing a magnetic attraction component in the cleaning element 110 and / or the transmission device 100, the transmission device 100 can maintain a connection relationship during the movement of the cleaning element 110. After the cleaning element 110 is placed at a specified position, the electromagnet can be disconnected to separate the cleaning element 110 from the transmission device 100. A magnetic attraction component can also be provided at a specified position to overcome the suction force between the cleaning element 110 and the transmission device 100 and adsorb the cleaning element 110 at the specified position.

[0171] In this embodiment, a threaded structure between the cleaning element 110 and the transmission device 100 is taken as an example. The cleaning element 110 and the transmission device 100 are threadedly connected to achieve the connection relationship maintained during the movement of the cleaning element 110 driven by the transmission device 100. After the cleaning element 110 is placed at a specified position, the cleaning element 110 can be separated from the transmission device 100 by rotating. A rotating mechanism can also be set at the specified position to rotate the cleaning element 110 away from the transmission device 100 and place the cleaning element 110 at the specified position.

[0172] In this embodiment, the clamping structure between the cleaning element 110 and the transmission device 100 is taken as an example. By clamping the cleaning element 110 and the transmission device 100, the connection relationship is maintained during the movement of the cleaning element 110 driven by the transmission device 100. After the cleaning element 110 is placed at a specified position, the position of the cleaning element 110 can be restricted so that the transmission device 100 can be separated from the cleaning element 110 after movement. A clamping device can also be provided at a specified position for clamping with the cleaning element 110 to disengage from the transmission device 100 and place the cleaning element 110 at a specified position.

[0173] In one embodiment, the cleaning element 110 includes at least two cleaning units. By providing at least two cleaning units, it is possible to replace rags of the same or different materials.

[0174] like Figure 1-Figure 6 As shown, in this embodiment, taking the cleaning element 110 including the first cleaning unit 1101 and the second cleaning unit 1102 as an example, the third transmission component 3 can be set to drive the cleaning element 110 to rotate 180° to switch the positions of the first cleaning unit 1101 and the second cleaning unit 1102. The rotation angle of the cleaning element 110 driven by the third transmission component 3 is set according to the number of cleaning units and the installation angle.

[0175] Among them, setting rags of the same material on several cleaning units can increase the frequency of replacing rags, reduce the dirt remaining in the rags, shorten the time for replacing and cleaning rags, shorten the time spent by the automatic cleaning device waiting for the rags to be cleaned each time it returns to the base station 200, improve cleaning efficiency and cleaning effects, and improve cleanliness.

[0176] Among them, setting rags of different materials on several cleaning units can increase the types of rags and replace rags according to different scenes, such as kitchens, grocery rooms and other different scenes. More suitable rags can also be replaced according to different materials of the surfaces to be cleaned, such as floors, tiles, carpets and other materials of the surfaces to be cleaned. This can meet the needs of different scenes and different materials of the surfaces to be cleaned, greatly improve the cleaning effect, and improve user satisfaction.

[0177] The number of the cleaning units may be one, two, three or other numbers.

[0178] In one possible implementation, Figure 7 and Figure 8 As shown, the transmission device 100 further includes a third transmission assembly 3, which is connected to the first transmission assembly 1, and the driving assembly 4 includes a second driving part 42, which is connected to the second driving part 42 and drives the cleaning element 110 to rotate to adjust the angle.

[0179] It can be understood that the first transmission component 1 drives the third transmission component 3 and the cleaning element 110 to move synchronously, and the second driving unit 42 drives the cleaning element 110 to rotate along the axis of the third transmission component 3 through the third transmission component 3 to adjust the angle of the cleaning element 110, thereby switching the positions of different cleaning units.

[0180] Among them, Figure 12-14 As shown, the third transmission assembly 3 includes a rotating connecting rod 33, and the output end of the second driving part 42 is connected to the rotating connecting rod 33 through a matching key 32, driving the rotating connecting rod 33 to rotate.

[0181] The second driving unit 42 includes a second motor and a second reduction mechanism, the second motor is connected to the second hinge unit, the second motor is connected to the second reduction mechanism, and the second reduction mechanism is connected to the rotating link 33 .

[0182] The second driving part 42 is fixed on the second hinge unit, and the output end is tightly matched with the matching key 32, driving the matching key 32 and the rotating connecting rod 33 to rotate, thereby driving the cleaning element 110 connected to the rotating connecting rod 33 to rotate, and driving the corresponding cleaning unit to rotate until it is opposite to the specified position.

[0183] Among them, Figure 12-14 As shown, when the transmission device 100 includes an articulated member 27 , the articulated member 27 includes a first articulated unit and a second articulated unit, the third transmission assembly 3 includes a bearing 31 , and the second articulated unit is connected to the rotating connecting rod 33 via the bearing 31 .

[0184] The second hinge unit may include a sleeve, and the second driving part 42 is fixed on the sleeve. The rotating connecting rod 33 and the sleeve may be matched with each other through a pin and a bearing 31.

[0185] It can be understood that the cleaning element replacement device is not limited to the specific structure of the first transmission assembly 1, the second transmission assembly 2 and the third transmission assembly 3, and can drive the cleaning element 110 through longitudinal movement, lateral movement, lifting and lowering, etc., so that the cleaning element 110 enters or moves out of the base station 200 accommodating cavity 220.

[0186] The cleaning element replacement device may further include a fourth transmission assembly, which is connected to the third transmission assembly 3 and may be arranged on the rotating connecting rod 33 for connecting the cleaning unit. The fourth transmission assembly may also be connected to the third driving unit, and the third driving unit drives the cleaning unit to rotate around its own axis through the fourth transmission assembly.

[0187] The second aspect of the present invention, as Figure 1-Figure 18 As shown, a base station 200 is provided, comprising any one of the cleaning element replacement devices in the first aspect, the base station 200 comprises a base station body 210 and a receiving cavity 220 , and the receiving cavity 220 is opened on the base station body 210 for receiving the cleaning element 110 .

[0188] It is understandable that the cleaning element replacement device can be set on the base station body 210 or outside the base station body 210. The accommodating cavity 220 can be provided with a device for cleaning the cleaning element 110, such as a cleaning brush, a scraper, etc.

[0189] The third driving part and the fourth transmission assembly can drive the cleaning unit to rotate and contact with the scraper and other devices in the accommodating chamber 220 to achieve cleaning of the cleaning unit. The scraper can also rotate and contact with the cleaning unit to achieve cleaning of the cleaning unit.

[0190] In one possible implementation, the accommodating chamber 220 includes a mounting portion, and the mounting portion is used to realize the disassembly of the cleaning element 110 and the transmission device 100 .

[0191] Among them, there may be at least one of a magnetic structure, a threaded structure, a clamping structure, and a mortise and tenon structure between the cleaning element 110 and the mounting portion, so that the cleaning element 110 can be removed from the transmission device 100.

[0192] Among them, this embodiment takes the magnetic attraction structure between the cleaning element 110 and the mounting part as an example. The mounting part may include a magnetic attraction part, and the cleaning element 110 includes an iron material. The cleaning element 110 is driven into the accommodating cavity 220 by the transmission device 100 and the cleaning element 110 is close to the mounting part. The cleaning element 110 is adsorbed by the magnetic attraction part of the mounting part, so that the cleaning element 110 can be removed from the transmission device 100 and fixed at a preset position in the accommodating cavity 220, so that the subsequent cleaning equipment can go to the preset position to replace the cleaning element 110.

[0193] A third aspect of the present invention provides an automatic cleaning system, comprising any one of the cleaning element replacement devices in the first aspect, or comprising any one of the base stations 200 in the second aspect.

[0194] In one possible implementation manner, the automatic cleaning system further includes a cleaning device, and the base station provides maintenance for the cleaning device.

[0195] The cleaning device may be a self-propelled cleaning robot or other types of cleaning robots that meet the requirements, wherein the self-propelled cleaning robot is a device that automatically performs cleaning operations in a certain area to be cleaned without user operation. Specifically, the cleaning device may include a sweeper, a sweeper and a mop-and-mop machine, and the like.

[0196] During the cleaning task, the cleaning element 110 is arranged below the cleaning device, so as to clean the dirt on the surface to be cleaned.

[0197] In the description of this specification, the description of the terms "one embodiment", "some embodiments", "specific embodiments", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0198] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
