[0001] This disclosure claims priority to China National Intellectual Property Administration application No. 202411645807.0, filed on November 15, 2024, entitled “Drive Mechanism and Cleaning System”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure belongs to the field of cleaning equipment technology, and in particular relates to a drive mechanism and a cleaning system. Background Technology

[0003] In existing technologies, robotic vacuum cleaners typically consist of a main unit and detachable cleaning components connected to it. In some scenarios, the cleaning components need to be detached, such as in homes with many carpets. While carpeted areas don't require mopping, if the robot carries the cleaning components through carpeted areas, two problems arise: first, water and stains from the cleaning components soil the carpet; second, the friction between the carpet and the cleaning components reduces the robot's maneuverability. Therefore, in some situations, the cleaning components need to be detached. However, current robotic vacuum cleaners require manual disassembly of the cleaning components, a cumbersome and inconvenient process for users.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0057] It should be noted that in this disclosure, the words "in one embodiment," "exemplarily," and "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this disclosure as "in one embodiment," "exemplarily," or "for example" should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the words "in one embodiment," "exemplarily," and "for example" is intended to present the relevant concepts in a specific manner.

[0058] The cleaning device includes a mopping function, which relies on cleaning element 2. When cleaning element 2 is no longer needed, it must be detached from the main unit. Since many homes have carpets, and carpeted areas don't require mopping, if the robot carries cleaning element 2 through carpeted areas, two problems arise: first, water and stains on cleaning element 2 will soil the carpet; second, the friction between the carpet and cleaning element 2 reduces the robot's versatility. Existing robotic vacuum cleaners require manual removal of the cleaning element, a cumbersome and inconvenient process for users.

[0059] Based on the above problems, this embodiment provides a drive mechanism 1 for disassembling the cleaning element 2 in the cleaning equipment. The drive mechanism 1 includes a drive device 12 and a movable component 13. The movable component 13 is connected to the drive device 12. When the drive device 12 is activated, it can drive the movable component 13 to move so as to unlock the cleaning element 2.

[0060] In a specific scenario, the drive mechanism 1 provided in this embodiment can be installed in the cleaning base station 4. When the cleaning equipment is located in the cleaning base station 4, the drive device 12 can be controlled to move, so that the drive device 12 drives the movable component 13 to move, thereby removing the cleaning element 2 from the main unit of the cleaning equipment.

[0061] In this embodiment, the cleaning element 2 is unlocked by using the drive mechanism 1, eliminating the need for manual disassembly of the cleaning element, which greatly facilitates user use and improves the user experience.

[0062]

[0063] In one embodiment, the drive mechanism 1 is also used for installing the cleaning element 2 in the cleaning device, that is, the movable component 13 can also lock the cleaning element 2 under the action of the drive device 12.

[0064] Specifically, when the cleaning equipment is located inside the cleaning base station 4, the drive device 12 can be controlled to move, thereby causing the movable component 13 to move, so as to remove the cleaning element 2 from the main unit of the cleaning equipment. At this time, the main unit can drive out of the cleaning base station 4. If the main unit drives back into the cleaning base station 4 and it is necessary to connect the cleaning element 2 to the main unit, the movable component 13 can also move under the drive of the drive device 12 to lock the cleaning element 2 on the main unit of the cleaning equipment.

[0065] The drive mechanism 1 provided in this embodiment can not only drive the movable component 13 to move to unlock the cleaning element 2 when the drive device 12 is activated, but also drive the movable component 13 to move so that the cleaning element 2 is locked on the main body of the cleaning device when the drive device 12 is activated.

[0066] In one embodiment, the movable member 13 moves in at least one of the following ways: moving or rotating, and unlocking and locking are achieved by rotating or moving the movable member 13.

[0067] For example, when the movable component 13 moves, the drive device 12 drives the movable component 13 to move along the first direction. The movement of the movable component 13 can drive the cleaning element 3 to move, thereby unlocking the cleaning element 2. When it is necessary to lock the cleaning element 2 on the main body of the cleaning device, the drive device 12 can drive the movable component 13 to move in the reset direction, so that the cleaning element 3 is reset, thereby locking the cleaning element 2 on the main body.

[0068] For example, when the movable component 13 rotates, the drive device 12 drives the movable component 13 to rotate in the first direction. The movement of the movable component 13 can drive the cleaning element 3 to move, thereby unlocking the cleaning element 2. When it is necessary to lock the cleaning element 2 on the main body of the cleaning device, the drive device 12 can drive the movable component 13 to rotate in the reset direction, so that the cleaning element 3 is reset, thereby locking the cleaning element 2 on the main body.

[0069] In this embodiment, the movable component 13 has a simple operating mode, which in turn makes the structure of the drive mechanism 1 simple.

[0070] In one embodiment, the movable member 13 moves within a plane.

[0071] In this embodiment, by controlling the movement of the movable member 13 within a plane, the movement mode of the movable member 13 is simple, which in turn facilitates the simplicity of the structure of the drive mechanism 1.

[0072] In one embodiment, a latch is provided between the cleaning element 2 and the main unit of the cleaning device. Unlocking and locking are achieved by the movement of the movable member 13 to unlock and reset the latch, respectively.

[0073] In this embodiment, the application scenario is when a latch is set between the cleaning element 2 and the main unit of the cleaning equipment. When the cleaning equipment is located inside the cleaning base station 4, the drive device 12 can be controlled to move, thereby driving the movable component 13 to move, so that the latch between the cleaning element 2 and the main unit of the cleaning equipment is in an unlocked state, that is, the cleaning element 2 is removed from the main unit. At this time, the main unit can drive out of the cleaning base station 4. If the main unit drives back into the cleaning base station 4 and needs to connect the cleaning element 2 to the main unit, the movable component 13 can also be reset when the drive device 12 is activated, so that the latch between the cleaning element 2 and the main unit of the cleaning equipment is in a locked state, thereby locking the cleaning element 2 to the main unit.

[0074] That is, the drive mechanism 1 provided in this embodiment can be applied to scenarios where a latch is set between the cleaning element 2 and the host of the cleaning equipment.

[0075] In one embodiment, the drive mechanism further includes a housing 11 for mounting on a clean base station 4, and a drive device 12 is disposed on the housing 11.

[0076] In this embodiment, the housing 11 provides protection for the drive device 12.

[0077] The driving mechanism 1 provided in this embodiment will be further described below with reference to the accompanying drawings.

[0078] Please refer to Figures 1 and 2, which are schematic diagrams of the external appearance of the drive mechanism 1 provided in an embodiment of this disclosure. Specifically, in one embodiment, the drive mechanism 1 includes a housing 11, a drive device 12, and a movable member 13. Figure 1 illustrates the housing 11, the drive device 12, and the movable member 13.

[0079] The drive mechanism 1 is used for the disassembly and assembly of the cleaning element 2 and the main unit in the cleaning equipment, wherein the cleaning equipment can be a sweeping robot.

[0080] Cleaning element 2 is typically connected to the main unit via a latch. The latch consists of two connected components, one on the cleaning element 2 and the other on the main unit. When external force causes these two components to disengage, the latch can be unlocked; this disengaged state is called the unlocked state. More than one latch can be installed between the cleaning element 2 and the main unit. When all latches between the cleaning element 2 and the main unit are in the unlocked state, the cleaning element 2 can be detached from the main unit. The state where the two components of the latch are connected is called the locked state. When all latches between the cleaning element 2 and the main unit are in the locked state, the cleaning element 2 is fixed to the main unit.

[0081] Existing methods require manual disassembly of the cleaning element 2, which is cumbersome and inconvenient for users. The drive mechanism 1 provided in this embodiment can be used for the disassembly and assembly of the cleaning element 2 and the main unit in the cleaning equipment.

[0082] Specifically, the drive mechanism 1 provided in this embodiment can be installed in the clean base station 4.

[0083] The cleaning base station 4 is used in conjunction with the cleaning equipment. The cleaning base station 4 is used to store the cleaning equipment when it is not in use, and to charge the cleaning equipment and clean the cleaning element 2. When the drive mechanism 1 provided in this embodiment is applied to the cleaning base station 4, the drive mechanism 1 can be used to unlock the latch between the cleaning element 2 and the main unit, so that the cleaning element 2 can be removed from the main unit. This allows the cleaning element 2 to remain in the cleaning base station, while the main unit can leave the cleaning base station 4 to perform sweeping and other operations.

[0084] In addition, when the drive mechanism 1 provided in this embodiment is applied to a cleaning base station, a corresponding number of drive mechanisms 1 can be set according to the number of latches between the cleaning element 2 and the host, so that each latch corresponds to a drive mechanism 1.

[0085] Please refer to Figures 1 and 2. The drive mechanism 1 includes a housing 11, which is used to be installed on the clean base station 4. At the same time, the housing 11 provides support for other components of the drive mechanism 1, such as the drive device 12, so that the other components of the drive mechanism 1 can be supported on the housing 11.

[0086] In this embodiment, the housing 11 is used to be installed on the cleaning base station 4. The shape and size of the housing 11 need to be adapted to the cleaning base station 4. At the same time, the cleaning base station 4 is also provided with an installation part so that when the housing 11 is installed on the installation part of the cleaning base station 4, it does not affect the cleaning equipment being stored inside the cleaning base station 4.

[0087] As described above, a corresponding number of drive mechanisms 1 are set according to the number of latches between the cleaning element 2 and the host. Therefore, the number of installation parts on the cleaning base station 4 needs to be consistent with the number of latches between the cleaning element 2 and the host. Each installation part is used to install the drive mechanism 1. The position of the installation part should be such that when the drive mechanism 1 is installed on the cleaning base station 4, each drive mechanism 1 corresponds to a latch, that is, each drive mechanism 1 can unlock the corresponding latch when it is activated.

[0088] In this embodiment, the movable component 13 is connected to the driving device 12, and the driving device 12 can drive the movable component 13 to move when it operates.

[0089] When the drive device 12 is activated, it can move the movable member 13. For example, the movable member 13 can move to two positions, namely a first position and a second position. The drive device 12 can move the movable member 13 from the first position to the second position, and at the same time, the drive device 12 can also move the movable member 13 from the second position to the first position. The first position and the second position are the two endpoints of the linear movement stroke of the movable member 13. The first position is the starting position when the movable member 13 has not extended relative to the housing 11, and the second position is the ending position after the movable member 13 has extended relative to the housing 11.

[0090] The latch between the cleaning element 2 and the main unit includes two connected components, defined as a first component and a second component, which are respectively disposed on the cleaning element 2 and the main unit. For example, when the drive device 12 moves the movable component 13 from the first position to the second position, the movable component 13 can move the first component disposed on the cleaning element 2 to separate it from the second component disposed on the main unit, thereby unlocking the latch. That is, when the drive device 12 moves the movable component 13 from the first position to the second position, the drive mechanism 1 unlocks the latch. When all latches are unlocked, the main unit can leave the cleaning base station 4. The movable component 13 is in contact with the first component in the second position. At this time, if the main unit is located inside the cleaning base station 4 and When the cleaning element 2 needs to be connected to the main unit, the control drive device 12 is activated to move the movable component 13 from the second position to the first position, so that the movable component 13 releases the restriction on the first component on the cleaning element 2. The first component moves back to its original position under the action of the locking buckle's own elasticity. The first component is connected to the second component set on the main unit, so that the locking buckle is in the locked state. That is, when the drive device 12 moves the movable component 13 from the second position to the first position, it is called the drive mechanism 1 locking. When all the locking buckles are in the locked state, the cleaning element 2 is fixed on the main unit.

[0091] When the cleaning element 2 is detached from the host under the action of the drive mechanism 1 and is located inside the cleaning base station 4, if the host needs to return to the cleaning base station 4 and the cleaning element 2 needs to be connected to the host, the drive device 12 can be controlled to move the movable component 13 from the second position to the first position before the host returns to the cleaning base station 4. After the host enters the cleaning base station 4 and moves into place, the first and second parts of the locking mechanism can be connected during the movement of the host. At this time, when the drive device 12 moves the movable component 13 from the second position to the first position, it is also referred to as the drive mechanism 1 locking.

[0092] Please refer to Figures 1 and 2, which show the external structure of the drive mechanism 1 when the movable member 13 is in the first position; when the movable member 13 is in the second position, the length of the movable member 13 extending out of the housing 11 increases based on Figures 1 and 2.

[0093] The starting and ending positions of the movable component 13 mentioned above can be controlled by the main control device of the cleaning base station 4 in this embodiment. For example, when it is necessary to move the movable component 13 from the first position to the second position, the main control device controls the drive device 12 to operate for a period of time. After the operation of the drive device 12 reaches the set time, the main control device controls the drive device 12 to stop operating. At this time, the movable component 13 moves to the second position. When it is necessary to move the movable component 13 from the second position to the first position, the main control device controls the drive device 12 to operate for a period of time. After the operation of the drive device 12 reaches the set time, the main control device controls the drive device 12 to stop operating. At this time, the movable component 13 moves to the first position. Alternatively, the drive mechanism 1 may also include a detection device 14, which is used to detect the moving position of the movable component 13. When the drive mechanism 1 provided in this embodiment is installed on the cleaning base station 4, the detection device 14 is connected to the control unit of the cleaning base station 4 via the drive device 12. The control unit controls the drive device 12 to operate according to the signal fed back by the detection device 14, so as to stop the movable component 13 at the first or second position. Please refer to Figure 1, which illustrates the detection device 14.

[0094] For example, the detection device 14 can detect the movement of the movable member 13 in real time; or, the movable member 13 has two positions when it moves, namely a first position and a second position. When the movable member 13 moves to the first position, the detection device 14 can detect a signal, and when the movable member 13 moves to the second position, the detection device 14 can also detect a signal. Specifically, when the drive device 12 moves and drives the movable component 13 to the second position, the detection device 14 detects the signal and transmits the signal to the control unit. After receiving the signal, the control unit sends a command to the drive device 12, causing the drive device 12 to stop moving, thereby allowing the movable component 13 to remain in the second position. At this time, the movable component 13 unlocks the latch 3 between the cleaning element 2 and the main unit. When the drive device 12 moves and drives the movable component 13 to the first position, the detection device 14 detects the signal and transmits the signal to the control unit. After receiving the signal, the control unit sends a command to the drive device 12, causing the drive device 12 to stop moving, thereby allowing the movable component 13 to remain in the first position. At this time, the action of the movable component 13 on the first part of the latch is released, so that the latch between the cleaning element 2 and the main unit can be locked.

[0095] In addition, when the host is located inside the cleaning base station and the cleaning element 2 needs to be removed from the host, the main control device of the cleaning base station 4 sends a command to the control unit, and the control unit controls the drive device 12 of the drive mechanism 1 to operate; when the host returns to the cleaning base station 4 and the cleaning element 2 needs to be connected to the host, the main control device of the cleaning base station 4 sends a command to the control unit, and the control unit controls the drive device 12 to operate.

[0096] The drive mechanism 1 provided in this embodiment drives the movable component 13 to move through the action of the drive device 12 to unlock the latch between the cleaning element 2 and the main unit, thereby realizing the automatic disassembly between the cleaning element 2 and the main unit without the need for manual disassembly of the cleaning element 2, which greatly facilitates the user's use and improves the user experience.

[0097] Please refer to Figures 3 and 4. Figure 3 is a structural schematic diagram of the connection between the drive device 12 and the movable member 13 provided in the embodiment of this disclosure; Figure 4 is another structural schematic diagram of the connection between the drive device 12 and the movable member 13 provided in the embodiment of this disclosure.

[0098] Regarding the structure of the drive device 12, in one embodiment, the drive device 12 includes a drive motor 121, an intermediate transmission assembly 122, and a lead screw assembly 123. The drive motor 121 is connected to the lead screw 1232 of the lead screw assembly 123 through the intermediate transmission assembly 122, and the movable member 13 is connected to the nut member 1231 in the lead screw assembly 123.

[0099] Please refer to Figures 3 and 4, which illustrate the drive motor 121, intermediate transmission assembly 122, and lead screw assembly 123.

[0100] The housing 11 of the drive motor 121 is supported on the casing 11. Exemplarily, the drive motor 121 may be disposed outside the casing 11, or the drive motor 121 may be disposed inside the casing 11. Preferably, the drive motor 121 is disposed outside the casing 11 to reduce the volume of the casing 11.

[0101] In this embodiment, the drive motor 121 is connected to the lead screw assembly 123 via an intermediate transmission assembly 122. Referring to Figures 3-4, the lead screw assembly 123 includes a lead screw 1232 and a nut component 1231. The lead screw 1232 passes through and is threadedly connected to the nut component 1231. When the drive motor 121 operates, the intermediate transmission assembly 122 drives the lead screw 1232 in the lead screw assembly 123 to rotate, thereby causing the nut component 1231 to move along the length direction of the lead screw 1232. Since the movable member 13 is connected to the nut component 1231, it can also move along the length direction of the lead screw 1232.

[0102] In this embodiment, the movable member 13 can be repeatedly moved between a first position and a second position by rotating the drive motor 121 in both forward and reverse directions. Specifically, when the drive motor 121 rotates in the reverse direction, the movable member 13 moves from the first position to the second position along the length direction of the lead screw 1232 through the intermediate transmission assembly 122 and the lead screw assembly 123; when the drive motor 121 rotates in the forward direction, the movable member 13 moves from the second position to the first position along the length direction of the lead screw 1232 through the intermediate transmission assembly 122 and the lead screw assembly 123.

[0103] In this embodiment, the drive motor 121 is connected to the control unit, which controls the operation of the drive motor 121 based on the signal fed back by the detection device 14. For example, the drive motor 121 is a DC motor or an AC motor.

[0104] In this embodiment, the rotational motion of the drive motor 121 is converted into the linear extension and retraction motion of the movable member 13 by the intermediate transmission assembly 122 and the lead screw assembly 123. When the movable member 13 extends, it pushes the latch to unlock the latch. When the movable member 13 retracts, the latch resets.

[0105] In this embodiment, the drive device 12 has a simple structure and stable transmission, which is beneficial for adjusting the position of the movable component 13. In addition, when the rotary motion is converted into linear motion by the lead screw assembly 123, the motion speed of the movable component 13 is constant, the force state is constant, and the drive mechanism 1 has high reliability.

[0106] As described above, the drive motor 121 is connected to the lead screw assembly 123 via an intermediate transmission assembly 122. The intermediate transmission assembly 122 can be a conveyor belt pulley structure. For example, the drive motor 121 is connected to a first pulley, and the lead screw 1232 of the lead screw assembly 123 is connected to a second pulley. The first and second pulleys are connected via a conveyor belt. Alternatively, in one embodiment, the intermediate transmission assembly 122 includes a first transmission assembly, which includes a worm gear 1221 and a turbine gear 1222. The worm gear 1221 and... The drive motor 121 is connected to the turbine 1222, which meshes with the worm gear 1221. The turbine 1222 is directly connected to the lead screw 1232 in the lead screw assembly 123. Alternatively, in another embodiment, the intermediate transmission assembly 122 includes a first transmission assembly and a second transmission assembly. The first transmission assembly includes the worm gear 1221 and the turbine 1222. The worm gear 1221 is connected to the drive motor 121, and the turbine 1222 meshes with the worm gear 1221. The turbine 1222 is connected to the lead screw assembly 123 through the second transmission assembly. Please refer to Figures 3 and 4, which illustrate the worm gear 1221 and the turbine 1222.

[0107] Preferably, as shown in Figures 3 and 4, the worm gear 1221 is coaxially arranged with the output shaft of the drive motor 121. For example, the worm gear 1221 and the drive motor 121 can be detachably connected; for instance, the worm gear 1221 and the output shaft 1211 of the drive motor 121 can be connected via a coupling; alternatively, the worm gear 1221 and the output shaft 1211 of the drive motor 121 can be made into a single integral structure.

[0108] In the embodiment where the worm gear 1222 is directly connected to the lead screw 1232 in the lead screw assembly 123, the specific transmission process is as follows: the drive motor 121 rotates, which in turn drives the worm gear 1221 to rotate. The rotation of the worm gear 1221 drives the worm gear 1222, which meshes with the worm gear 1221, to rotate. The rotation of the worm gear 1222 drives the lead screw 1232 to rotate synchronously, which in turn drives the nut component 1231 to move along the length direction of the lead screw 1232, thereby realizing the adjustment of the position of the movable component 13.

[0109] The worm gear drive has a speed reduction function. Through the meshing of the worm gear, a higher transmission ratio can be achieved, thereby reducing the speed, increasing the torque, and reducing noise. This is beneficial for the detection device 14 to detect the position of the movable member 13, and for the movable member 13 to apply force to the locking buckle on the cleaning element 2. Since the worm gear drive can change the transmission direction and achieve a compact transmission, it is convenient for the drive mechanism 1 to be installed on the cleaning base station. In addition, the use of the worm gear drive can achieve self-locking of the mechanism, so that the position of the movable member 13 can be maintained even if the drive motor 121 is de-energized.

[0110] By directly connecting the turbine 1222 to the lead screw 1232 in the lead screw assembly 123, the structure of the intermediate transmission assembly 122 can be simplified, thereby reducing the size of the drive mechanism 1 and also reducing transmission noise.

[0111] In the embodiment where the turbine 1222 is connected to the lead screw assembly 123 via the second transmission assembly, the specific transmission process is as follows: the drive motor 121 rotates, thereby driving the worm 1221 to rotate. The rotation of the worm 1221 drives the turbine 1222, which meshes with the worm 1221, to rotate. The rotation of the turbine 1222 drives the lead screw 1232 to rotate via the second transmission assembly, thereby driving the nut component 1231 to move along the length direction of the lead screw 1232, thereby realizing the adjustment of the position of the movable component 13.

[0112] The benefits of worm gear transmission have been described above and will not be elaborated further here. The worm gear 1222 is connected to the lead screw assembly 123 via a second transmission assembly. By adding a second transmission assembly between the worm gear 1222 and the lead screw 1232, the relative position of the lead screw assembly 123 and the worm gear 1222 can be changed, which is beneficial for the layout of the position of the movable member 13.

[0113] Regarding the second transmission assembly, in one embodiment, please refer to Figures 3 and 4. The second transmission assembly includes a first gear 1223 and a second gear 1224. The first gear 1223 is coaxially arranged with the turbine 1222 and supported in the housing 11. The second gear 1224 meshes with the first gear 1223, and the lead screw 1232 in the lead screw assembly 123 passes through the second gear 1224. The diameter of the second gear 1224 is larger than the diameter of the first gear 1223.

[0114] Please refer to Figures 3 and 4, which illustrate the first gear 1223 and the second gear 1224. The second transmission component is a gear drive, which has the advantage of stable transmission.

[0115] In an embodiment where the second transmission assembly includes a first gear 1223 and a second gear 1224, the specific transmission process is as follows: the drive motor 121 rotates, which in turn drives the worm gear 1221 to rotate. The rotation of the worm gear 1221 drives the turbine gear 1222, which meshes with the worm gear 1221, to rotate. The rotation of the turbine gear 1222 drives the first gear 1223, which is coaxially arranged with the turbine gear 1222, to rotate. The rotation of the first gear 1223 drives the second gear 1224, which meshes with the first gear 1223, to rotate. The second gear 1224 drives the lead screw 1232 to rotate, which in turn drives the nut component 1231 to move along the length direction of the lead screw 1232, thereby realizing the adjustment of the position of the movable component 13.

[0116] In this embodiment, by setting the diameter of the second gear 1224 to be larger than that of the first gear 1223, a speed reduction effect can be achieved. Based on the speed reduction effect of the worm gear, the first gear 1223 and the second gear 1224 can achieve two-stage speed reduction, which facilitates the detection device 14 to detect the position of the movable member 13 and facilitates the movable member 13 to apply force to the locking buckle on the cleaning element 2.

[0117] Preferably, as shown in Figure 3, the diameter of the first gear 1223 is smaller than the diameter of the turbine 1222. The first gear 1223 rotates synchronously with the turbine 1222. By setting the diameter of the first gear 1223 to be smaller than the diameter of the turbine 1222, it is beneficial to reduce the diameter of the second gear 1224, thereby reducing the volume of the drive mechanism 1.

[0118] Please refer to Figures 5-8. Figure 5 is an exploded view of the drive mechanism 1 provided in this embodiment; Figure 6 is an internal structure diagram of the drive mechanism 1 provided in this embodiment (the second housing 112 is not shown); Figure 7 is an internal structure diagram of the drive mechanism 1 provided in this embodiment (the second housing 112 and the oil baffle 113 are not shown); Figure 8 is an internal structure diagram of the drive mechanism 1 provided in this embodiment (the first housing 111 is not shown).

[0119] In one specific embodiment, please refer to FIG5, the housing 11 includes a first housing 111 and a second housing 112, the second housing 112 is located on one side of the first housing 111 and the two are connected; a turbine receiving cavity is formed in the first housing 111, the worm 1221 and the turbine 1222 are disposed in the turbine receiving cavity, the first gear 1223 is located in the second housing 112, and an oil baffle 113 is disposed between the turbine 1222 and the first gear 1223.

[0120] Please refer to Figure 5, which illustrates the first housing 111 and the second housing 112. The first housing 111 and the second housing 112 are detachably connected. The intermediate transmission assembly 122 and the lead screw assembly 123 of the drive device 12 are located inside the first housing 111 and the second housing 112. The worm gear 1221 and the turbine 1222 are disposed in the turbine housing cavity inside the first housing 111, and the first gear 1223 is located inside the second housing 112. An oil baffle 113 is disposed between the turbine 1222 and the first gear 1223.

[0121] In this embodiment, the meshing part of the worm gear 1222 and the worm 1221 is sealed by the oil baffle 113 to prevent the grease from leaking out.

[0122] For example, the first housing 111 and the second housing 112 are detachably connected by a connector, which is a screw or bolt.

[0123] For example, please refer to Figure 5. The first housing 111 is provided with a motor mounting groove 1113. The motor mounting groove 1113 is provided with a shaft hole 1114. The output shaft 1211 of the drive motor 121 is inserted into the shaft hole 1114. One end of the drive motor 121 with the output shaft is located in the motor mounting groove 1113. The housing of the drive motor 121 is detachably connected to the first housing 111 through a connector.

[0124] Regarding the fixing of the oil baffle 113, preferably, as shown in Figure 7, a step is provided on the first housing 111, the step having a step surface 1111. As shown in Figure 8, a protrusion 1121 is provided on the side of the second housing 112 facing the first housing 111, and the oil baffle 113 is limited between the step surface 1111 and the protrusion 1121. Alternatively, a protrusion may be provided on the side of the first housing 111 facing the second housing 112, and a step may be provided on the second housing 112.

[0125] To facilitate the positioning of the oil baffle 113 on the stepped surface of the first housing 111, in a specific example, please refer to Figures 6 and 7, a positioning pin 1112 is provided on the stepped surface of the first housing 111, and a positioning hole is provided on the oil baffle 113, with the positioning pin 1112 inserted into the positioning hole on the oil baffle 113.

[0126] For example, the worm gear 1222 and the first gear 1223 are integrally formed. Specifically, referring to Figure 7, an intermediate cylinder 1126 is provided between the worm gear 1222 and the first gear 1223, and the worm gear 1222, the intermediate cylinder 1126, and the first gear 1223 are integrally formed. The oil baffle plate 113 is provided with an oil baffle plate through hole, and the intermediate cylinder 1126 passes through the oil baffle plate through hole on the oil baffle plate 113. By providing the intermediate cylinder 1126, it is convenient to provide the oil baffle plate 113 between the worm gear 1222 and the first gear 1223.

[0127] In one specific embodiment, referring to Figures 7 and 8, the drive motor 121 is positioned at the top. The worm gear 1221 is coaxially arranged with the output shaft 1211 of the drive motor 121. The worm wheel 1222 is coaxially arranged with the first gear 1223, and the axes of the worm wheel 1222 and the first gear 1223 are perpendicular to the axis of the worm gear 1221. The axis of the lead screw 7 is parallel to the axes of the worm wheel 1222 and the first gear 1223, and the lead screw 7 is located below the worm wheel 1222 and the first gear 1223.

[0128] Specifically, please refer to Figure 7. The shaft supporting the worm gear 1222 and the first gear 1223 is the first rotating shaft 1225. One end of the first rotating shaft 1225 is rotatably connected to the first housing 111 through a bearing, and the other end of the first rotating shaft 1225 is rotatably connected to the second housing 112 through a bearing.

[0129] Specifically, one end of the lead screw 7 is rotatably connected to the first housing 111 via a bearing, and the other end of the lead screw 7 is rotatably connected to the second housing 112 via a bearing.

[0130] In one embodiment, as shown in Figures 8 and 9, a connecting portion 1233 is provided on the nut component 1231, and a movable member 13 is provided on the connecting portion 1233; a guide hole 12331 is provided on the connecting portion 1233, and a guide rod 1234 is provided on the housing 11. The guide rod 1234 is parallel to the lead screw 1232 of the lead screw assembly 123, and the guide rod 1234 passes through the guide hole 12331 and is slidably connected to the connecting portion 1233.

[0131] Please refer to Figure 8, which shows the nut component 1231, the connecting part 1233, and the guide rod 1234 provided on the connecting part 1233.

[0132] The two ends of the guide rod 1234 are fixedly connected to the first housing 111 and the second housing 112 respectively. The guide rod 1234 can limit the nut component 1231 so that when the lead screw 1232 rotates, the nut component 1231 moves along the length extension direction of the lead screw 1232 and the guide rod 1234.

[0133] In this embodiment, the movable component 13 and the guide rod 1234 are both provided on the connecting part 1233 to facilitate a compact structural layout.

[0134] For example, the nut component 1231 and the connecting portion 1233 are integrally formed. Specifically, referring to FIG9, the nut component 1231 is rectangular block-shaped, and the connecting portion 1233 is disposed below the nut component 1231 and the two are connected by a rounded transition.

[0135] Preferably, referring to Figure 8, there are two guide rods 1234, and the two guide rods 1234 are located on both sides of the movable member 13, so as to facilitate the stable movement of the guide nut component 1231 along the length extension direction of the guide rod 1234. Specifically, referring to Figure 8, the movable member 13 is located in the middle region of the connecting part 1233, and guide holes 12331 are provided on the ends of the connecting part 1233 that protrude from the left and right sides of the nut component 1231. The guide holes 12331 are symmetrically distributed. Referring to Figure 8, the guide rods 1234 pass through the guide holes 12331.

[0136] For example, guide rod 1234 is a cylindrical rod.

[0137] In one embodiment, referring to FIG8, the detection device 14 includes a first detection component 141 and a second detection component 142. A detection part 143 is provided on the nut component 1231. When the movable member 13 is in the first position, the detection part 143 triggers the first detection component 141, that is, the first detection component 141 can detect the detection part 143. When the movable member 13 is in the second position, the detection part 143 triggers the second detection component 142, that is, the second detection component 142 can detect the detection part 143.

[0138] In this embodiment, since both the movable member 13 and the detection part 143 are mounted on the nut component 1231, the position of the movable member 13 can be determined by detecting the position of the detection part 143. In this embodiment, mounting the detection part 143 on the nut component 1231 facilitates a compact structure for the drive mechanism 1.

[0139] For example, referring to Figures 8 and 9, the probe 143 is shown to be disposed on the side of the nut component 1231. Preferably, the probe 143 and the nut component 1231 are integrally formed.

[0140] Preferably, the detector 143 has a thin sheet structure, which simplifies the structure of the detector 143 while enabling it to cooperate with the first detection component 141 and the second detection component 142.

[0141] For example, the number of detection parts 143 is one; or, referring to Figures 8 and 9, two detection parts 143 are provided on the nut component 1231 along the height direction, the detection part 143 provided below is the first detection part, and the detection part 143 provided above is the second detection part. When the movable member 13 is in the first position, the first detection component 141 can detect the first detection part, and when the movable member 13 is in the second position, the second detection component 142 can detect the second detection part.

[0142] In one embodiment, the first detection component 141 is a photoelectric switch, a micro switch, or a Hall sensor; the second detection component 142 is a photoelectric switch, a micro switch, or a Hall sensor; so that the first detection component 141 and the second detection component 142 can accurately detect the position of the movable member 13.

[0143] The first detection component 141 and the second detection component 142 may be the same, or they may be different. Preferably, the first detection component 141 and the second detection component 142 are the same component. For example, both the first detection component 141 and the second detection component 142 may be photoelectric switches. A photoelectric switch is a sensor that uses the photoelectric effect to detect the presence, position, distance, and other information of an object. A photoelectric switch typically consists of a light emitter (such as a light-emitting diode) and a receiver (such as a phototransistor). When the light emitted by the light emitter is blocked or reflected by an object, the intensity of the light received by the receiver changes, thereby generating an electrical signal output.

[0144] Please refer to Figure 8. The first detection component 141 and the second detection component 142 are offset vertically along the height direction. Figure 8 shows the movable member 13 in the first position, at which time the detector 143 located below is located between the emitter and receiver of the first detection component 141; when the movable member 13 is in the second position, the detector 143 located above is located between the emitter and receiver of the second detection component 142.

[0145] Alternatively, a detection part 143 can be provided on the nut component 1231. When the movable member 13 is in the first position, the detection part 143 is located between the light emitter and the receiver of the first detection component 141; when the movable member 13 is in the second position, the detection part 143 is located between the light emitter and the receiver of the second detection component 142.

[0146] In one embodiment, referring to FIG8, the detection device 14 further includes a circuit board 144, on which the first detection component 141 and the second detection component 142 are both disposed. The circuit board 144 is fixed to the outer side of the housing 11, and the first detection component 141 and the second detection component 142 extend through the housing 11 into the interior of the housing 11.

[0147] In this embodiment, the circuit board 144 is connected to the control unit, and the first detection component 141 and the second detection component 142 are disposed on the same circuit board 144, which simplifies the structure of the detection device 14.

[0148] Preferably, a plane that fits against the circuit board 144 is formed on the outer side of the housing 11 to facilitate the stable fixing of the circuit board 144 to the housing 11.

[0149] For example, the circuit board 144 is detachably connected to the housing 11 via a connection.

[0150] Please refer to Figures 10 and 11. Figure 10 is a schematic diagram of the structure of the drive mechanism 1 cooperating with the locking buckle 3 between the cleaning element 2 and the main unit; Figure 11 is a partial enlarged view of point A in Figure 10.

[0151] This embodiment provides a cleaning system, including:

[0152] Clean base station 4 is provided with a drive mechanism 1 provided in any of the above embodiments; optionally, there may be two or more drive mechanisms 1.

[0153] The cleaning device includes a cleaning element 2 and a main unit. Preferably, the cleaning element 2 is connected to the main unit via a latch 3. There can be multiple latches 3, and each latch 3 corresponds to a drive mechanism 1.

[0154] The specific structure of drive mechanism 1 has been described above and will not be repeated here.

[0155] The cleaning equipment includes a cleaning element 2 and a main unit. When the cleaning equipment is located inside the cleaning base station 4, the driving device 12 can be controlled to move, thereby driving the movable component 13 to remove the cleaning element 2 from the main unit of the cleaning equipment.

[0156] Preferably, the drive mechanism 1 can not only drive the movable component 13 to move to unlock the cleaning element 2 when the drive device 12 is activated, but also drive the movable component 13 to move so that the cleaning element 2 is locked on the main body of the cleaning device when the drive device 12 is activated.

[0157] In a scenario where the cleaning element 2 is connected to the host via the latch 3, specifically, when the user sends an instruction to the cleaning base station 4 or the cleaning equipment to remove the cleaning element 2 from the host, the cleaning equipment moves into the cleaning base station 4; the main control device of the cleaning base station 4 sends an instruction to the control unit, and the control unit controls the drive device 12 of the drive mechanism 1 to move. The drive device 12 moves the movable component 13 of the drive mechanism 1 from the first position to the second position. When the movable component 13 moves to the second position, the detection device 14 of the drive mechanism 1 detects the position information of the movable component 13 and sends a signal to the control unit. The control unit controls the drive device 12 to stop moving. At this time, the movable component 13 of each drive mechanism 1 acts on the corresponding latch 3 to make the latch 3 in the unlocked state. When all latches 3 are in the unlocked state, the host can leave the cleaning base station 4. When a user sends an instruction to the cleaning base station 4 or the host to install the cleaning element 2 onto the host, the host moves toward the cleaning base station 4. The main control device of the cleaning base station 4 sends an instruction to the control unit. The control unit controls the drive device 12 to move the movable component 13 from the second position to the first position. When the movable component 13 moves to the first position, the detection device 14 of the drive mechanism 1 detects the position information of the movable component 13 and sends a signal to the control unit. The control unit controls the drive device 12 to stop moving. At this time, the movable components 13 of each drive mechanism 1 move away from the corresponding latch 3. The movable component 13 cancels its effect on the latch 3, so that the latch 3 between the cleaning element 2 and the host can be locked. When all latches 3 are locked, the cleaning element 2 is fixed on the host.

[0158] The cleaning system provided in this embodiment achieves automatic disassembly between the cleaning element 2 and the main unit through the drive mechanism 1, eliminating the need for manual disassembly of the cleaning element 2, which greatly facilitates user use and enhances the user experience.

[0159] In one specific example, the cleaning base station 4 is equipped with two drive mechanisms 1, and the cleaning element 2 is connected to the host via two latches 3. Please refer to Figure 10, which illustrates the two drive mechanisms 1, each corresponding to a latch 3. Figure 10 shows that the movable component 13 of the drive mechanism 1 is not in contact with the latch 3; at this time, the latch 3 is in a locked state.

[0160] Please refer to Figures 12-17. Figure 12 is an exploded view of the cleaning element 2 and the host connection part 5 provided in the embodiment of this disclosure; Figure 13 is an exploded view of the cleaning element 2 provided in the embodiment of this disclosure; Figure 14 is a partial enlarged view of point B in Figure 13; Figure 15 is a structural schematic diagram of the cleaning element 2 provided in the embodiment of this disclosure; Figure 16 is a cross-sectional schematic diagram of the cleaning element 2 and the host connection part 5 provided in the embodiment of this disclosure; Figure 17 is a partial enlarged view of point C in Figure 16.

[0161] In one embodiment, the latch 3 includes a button 31, a latching element 32, and an elastic element 33. The latching element 32 is disposed on the main unit, the button 31 is disposed on the cleaning element 2, and the elastic element 33 connects the button 31 and the cleaning element 2. When the movable member 13 extends out of the housing 11, it can push the button 31 to squeeze the elastic element 33, so that the button 31 is disengaged from the latching element 32 to achieve unlocking. When the movable member 13 retracts into the housing, it can reset the button 31 so that the button 31 is connected to the latching element 32.

[0162] Please refer to Figure 12, which illustrates the connection between the cleaning element 2 and the main unit connection part 5. The main unit connection part 5 is a part of the main unit structure, and the main unit connection part 5 is connected to the cleaning element 2 via a latch 3. Figure 12 also shows the button 31 provided on the cleaning element 2 and the latch 32 provided on the main unit connection part 5.

[0163] Please refer to Figure 14, which illustrates the button 31 and the elastic element 33. The button 31 is connected to the cleaning element 2 through the elastic element 33. Please refer to Figure 17, which illustrates the engagement of the button 31 and the latching element 32. In Figure 17, the latch 3 is shown in the locked state. If the button 31 is pushed in Figure 17, the button 31 will move in the X direction and press the elastic element 33. When the button 31 moves a certain distance, the button 31 disengages from the latching element 32, so that the latch 3 is in the unlocked state.

[0164] When the host is located inside the cleaning base station 4 and the cleaning element 2 needs to be removed from the host, the drive device 12 that controls each drive mechanism 1 moves to drive each movable component 13 from the first position to the second position. During the movement, the movable component 13 contacts the corresponding button 31 and squeezes the button 31 to compress the elastic element 33. When the movable component 13 is in the second position, the movable component 13 pushes the button 31 to a position where it is completely disengaged from the buckle 32, thereby unlocking the latch 3.

[0165] Please refer to Figures 14 and 15. An insertion port 214 is formed on the cleaning element 2. Please refer to Figure 17. The latch 32 is inserted into the cleaning element 2 through the insertion port 214. When the latches 3 between the cleaning element 2 and the main unit are both in the unlocked state, when the main unit moves away from the cleaning element 2, the latch 32 extends out of the insertion port 214, and the cleaning element 2 separates from the main unit.

[0166] When the host returns to the cleaning base station 4 and moves into place, the latch 32 of the latch 3 is inserted into the corresponding insertion port 214, controlling the drive device 12 of each drive mechanism 1 to move each movable component 13 from the second position to the first position. The button 31 is reset under the elastic force of the elastic member 33, so that the button 31 of each latch 3 is engaged with the latch 32, realizing the connection of the cleaning element 2 to the host.

[0167] Furthermore, the connection between the cleaning element 2 and the main unit can be as follows: Before the main unit returns to the cleaning base station 4, the drive device 12 has already moved each movable component 13 from the second position to the first position, and the button 31 is reset under the elastic force of the elastic member 33. During the process of the main unit moving towards the cleaning element 2, the latching member 32 of the locking buckle 3 pushes the button 31, causing the button 31 to move and compress the elastic member 33 until the latching member 32 moves into place. Then, the button 31 is reset under the action of the elastic member 33, so that the latching member 32 and the button 31 are engaged, thereby realizing the connection of the cleaning element 2 to the main unit.

[0168] The latch 3 provided in this embodiment has a simple structure and is easy to cooperate with the drive mechanism 1 to realize the automatic disassembly between the cleaning element 2 and the main unit.

[0169] Existing technologies employ magnetic attraction to connect cleaning components to the main unit. For example, a permanent magnet is mounted on the cleaning component, and a corresponding permanent magnet or electromagnet is positioned on the main unit to attract it. The mop module is then detached or reattached by controlling the presence or absence of magnetic force. However, this magnetic connection method has several drawbacks: the magnetic force of the permanent magnet is dependent on its size; larger magnets occupy too much space, while smaller magnets cannot reliably hold large cleaning components. Furthermore, the high-temperature mop washing and drying functions commonly found in current cleaning components pose a risk of rusting and demagnetization due to the high temperature and humidity environment. In this embodiment, the automatic detachment of the cleaning component 2 from the main unit is achieved through the cooperation of the drive mechanism 1 and the latch 3. This allows for compatibility with larger cleaning components 2, and the latch 3 offers higher reliability under conditions of high temperature, high humidity, and vibration.

[0170] Preferably, the elastic element 33 is a spring.

[0171] Specifically, please refer to Figure 17. Button 31 includes button hook 312, and fastener 32 includes fastener hook 321. Under the elastic action of elastic member 33, button hook 312 abuts against fastener hook 321 to make button 31 engage with fastener 32, thereby making cleaning element 2 connected to the host through latch 3.

[0172] In one embodiment, the button 31 includes a button hook 312, on which a guide slope 3121 is formed. The guide slope 3121 is used to push the button 31 to move and squeeze the elastic member 33 when the fastener 32 presses the button 31.

[0173] Please refer to Figure 17, which illustrates the guide slope 3121 on the button hook 312. As described above, before the main unit returns to the cleaning base station 4, the drive device 12 has already moved each movable component 13 from the second position to the first position. The button 31 is reset under the elastic force of the elastic member 33, that is, the button 31 is in the position shown in Figure 17. At this time, during the process of the main unit moving towards the cleaning element 2, the latch hook 321 of the latching member 32 first presses the guide slope 3121 on the button hook 312, pushing the button 31 to move and press the elastic member 33 until the latching member 32 moves into place. Then, the button 31 is reset under the action of the elastic member 33, realizing the engagement between the button 31 and the latching member 32.

[0174] In one embodiment, the cleaning element 2 includes a cleaning housing 21, and two oppositely arranged mounting holes 211 are provided on the circumferential side of the cleaning housing 21. The button 31 is inserted into the corresponding mounting hole 211, and a mating groove 311 is formed on the button 31 to cooperate with the free end of the movable member 13.

[0175] Please refer to Figure 14, which illustrates the mounting hole 211. Please refer to Figure 16, which illustrates the two mounting holes 211 that are arranged opposite each other.

[0176] In one specific example, please refer to Figure 13. The cleaning housing 21 includes an upper cleaning housing 215 and a lower cleaning housing 216. The upper cleaning housing 215 is disposed above the lower cleaning housing 216 and the two are connected. Please refer to Figure 14, which illustrates the limiting plate structure 217. The upper cleaning housing 215, the lower cleaning housing 216, and the limiting plate structure 217 form an assembly hole 211. The limiting plate structure 217 is provided with an insertion port 214 for inserting the fastener 32.

[0177] Specifically, please refer to Figure 14. The limiting plate structure 217 includes a first limiting plate 2171, a second limiting plate 2172, and a third limiting plate 2173. The first limiting plate 2171 and the third limiting plate 2173 are arranged in parallel. The two ends of the first limiting plate 2171 and the third limiting plate 2173 on the same side extend to the edge of the lower cleaning housing 216, respectively. The second limiting plate 2172 connects the other two ends of the first limiting plate 2171 and the third limiting plate 2173. An insertion port 214 is formed on the first limiting plate 2171.

[0178] Please refer to Figure 14. The elastic element 33 connects the button 31 and the second limiting plate 2172. Preferably, the button 31 does not protrude from the mounting hole 211 along the direction of elastic deformation of the elastic element 33.

[0179] Preferably, as shown in Figure 14, a spring post 218 is provided on the second limiting plate 2172, and the elastic element 33 is a spring and is sleeved on the spring post 218. By providing the spring post 218 on the second limiting plate 2172, the position of the elastic element 33 is limited.

[0180] Preferably, as shown in Figure 14, not only is a spring post 218 provided on the second limiting plate 2172, but also on the button 31. When the button 31 presses the elastic member 33, the spring post 218 on the button 31 inserts into the elastic member 33.

[0181] In one example, as shown in Figure 14, a perforated hole 313 is provided on the button 31, and an elastic element 33 is inserted into the end of the button 31 near the second limiting plate 2172 and extends out of the perforated hole 313. By providing a perforated hole 313 on the button 31, the weight of the button 31 can be reduced, saving costs. In this embodiment, by providing an elastic element 33 inserted into the end of the button 31 near the second limiting plate 2172 and extending out of the perforated hole 313, the layout of the latch on the cleaning element 2 can be made more compact.

[0182] In this embodiment, button 31 is inserted into the corresponding mounting hole 211, that is, button 31 is not exposed outside the cleaning housing 21, making the structure of the cleaning element 2 aesthetically pleasing.

[0183] In this embodiment, please refer to FIG14. A mating groove 311 is formed on the button 31 to cooperate with the free end of the movable member 13. By providing the mating groove 311, when the movable member 13 of the drive mechanism 1 extends, it can be inserted into the mating groove 311, and when the movable member 13 continues to extend, it can squeeze the button 31 and drive the button 31 to move.

[0184] Please refer to Figure 10. A drive mechanism 1 is provided on each of the left and right sides of the cleaning element 2. When the drive device 12 that controls the two drive mechanisms 1 is activated to drive each movable component 13 to be inserted into the mating groove 311 of the button 31, the two movable components 13 can limit the cleaning element 2.

[0185] In this embodiment, by providing a mating groove 311 on the button 31, when the movable member 13 squeezes the button 31 to unlock the latch 3, the cleaning element 2 can be limited on the cleaning base station 4 by the drive mechanism 1.

[0186] Regarding the movable member 13, preferably, as shown in FIG11, the free end of the movable member 13 is pointed, so that the movable member 13 can be inserted into the mating groove 311 on the button 31.

[0187] As described above, when the latch 3 is in the unlocked state, the cleaning element 2 is limited to the cleaning base station 4 by the drive mechanism 1. In order to further limit the position of the cleaning element 2 on the cleaning base station 4, in one embodiment, a support part 41 is provided on the inner side wall of the cleaning base station 4, and a mating hole 212 is opened on the circumferential side of the cleaning element 2. The mating hole 212 is located in the middle of the two latches 3, and the support part 41 is inserted into the mating hole 212.

[0188] Please refer to Figure 12, which illustrates the mating hole 212 on the cleaning element 2; please refer to Figure 18, which illustrates the support portion 41 provided on the cleaning base station 4. When the cleaning equipment moves into the cleaning base station 4 and is in place, the support portion 41 on the cleaning base station 4 inserts into the mating hole 212 on the cleaning element 2. The support portion 41 provides support for the cleaning element 2.

[0189] Please refer to Figure 12. The mating hole 212 is located between the two latches 3. When the latches 3 are in the unlocked state, the cleaning element 2 can be limited on the cleaning base station 4 by the drive mechanism 1; the two drive mechanisms 1 and a support part 41 form a three-point support for the cleaning element 2, so that the cleaning element 2 is stably limited on the cleaning base station 4.

[0190] In one embodiment, the host is provided with two or more detection switches 51, which are distributed at both ends of the host, and the cleaning element 2 is provided with a contact surface 213 that contacts the detection switches 51.

[0191] Please refer to Figure 12, which illustrates the connection between the cleaning element 2 and the main unit connection part 5. The main unit connection part 5 is a partial structure of the main unit, and it is connected to the cleaning element 2 via a latch 3. Figure 12 also shows a detection switch 51 near one end, and a detection switch 51 is also provided at the other symmetrical end of the main unit connection part 5. Preferably, each end of the main unit connection part 5 is provided with one or more detection switches 51.

[0192] Please refer to Figure 15, which illustrates the contact surfaces 213 on the cleaning element 2. The two contact surfaces 213 are located near both ends of the cleaning element 2. The two contact surfaces 213 in the cleaning element 2 respectively cooperate with the detection switches 51 at the corresponding ends of the main unit connection part 5.

[0193] In this embodiment, detection switches 51 are distributed at both ends of the host to detect whether the cleaning element 2 is installed in place on the host. Specifically, when the cleaning element 2 is positioned on the cleaning base station 4, if the host returns to the cleaning base station 4 and both detection switches 51 at both ends of the host connection part 5 are triggered, it indicates that the host has moved into place; if the detection switch 51 at one end of the host connection part 5 is triggered but the detection switch 51 at the other end is not triggered, it indicates that the host has not moved into place. In this case, the host continues to move into the cleaning base station 4, so that both detection switches 51 at both ends of the host connection part 5 are triggered, and the main control device of the cleaning base station 4 determines that the host has moved into place.

[0194] When it is necessary to install the cleaning element 2 located in the cleaning base station 4 on the host, the main control device can send a command to the control unit after the main control device determines that the host has been moved into place, so that the control unit controls the drive device 12 to operate.

[0195] When the cleaning element 2 is removed from the main unit by the drive mechanism 1, if the two detection switches 51 are not triggered, the main control device determines that the cleaning element 2 has been removed from the main unit.

[0196] For example, the detection switch 51 is a micro switch.

[0197] In one embodiment, the cleaning base station 4 is provided with a receiving groove 43 for accommodating cleaning equipment. Two or more guide wheels 42 are provided on the opening side of the receiving groove 43. The two or more guide wheels 42 are respectively provided on both sides of the opening of the receiving groove 43. When the cleaning equipment enters or leaves the cleaning base station 4, the guide wheels 42 come into contact with the cleaning equipment and roll.

[0198] In this embodiment, the cleaning base station 4 is equipped with guide wheels 42 to facilitate the cleaning equipment to enter or leave the cleaning base station 4.

[0199] In one embodiment, a cleaning brush and a cleaning brush drive device are provided on the cleaning base station 4. The cleaning brush drive device is connected to the cleaning brush and can drive the cleaning brush to move back and forth relative to the cleaning element 2 so as to clean the cloth on the cleaning element 2.

[0200] The cleaning housing 21 includes an upper cleaning housing 215 and a lower cleaning housing 216. The upper cleaning housing 215 is disposed above the lower cleaning housing 216, and a wiping cloth is disposed on the side of the lower cleaning housing 216 opposite to the upper cleaning housing 215.

[0201] In addition, the cleaning base station 4 also includes a water tank and a pipeline connecting the water tank and the cleaning brush. Water is continuously supplied to the cleaning brush through the water tank, so that the water spray holes on the cleaning brush continuously spray water onto the cleaning element 2 to clean the cleaning element 2.

[0202] When the main unit of the cleaning equipment moves away from the cleaning base station 4 and the cleaning element 2 is located at the cleaning base station 4, the cleaning element 2 can be cleaned by the cleaning brush and the cleaning brush drive device.

[0203] The beneficial effects of this disclosure are as follows: The driving mechanism provided in this embodiment drives the movable component to move through the driving device to unlock the latch between the cleaning element and the main unit, thereby realizing the automatic disassembly between the cleaning element and the main unit without the need for manual disassembly of the cleaning element, which greatly facilitates the user's use and improves the user experience.

[0204] The cleaning system provided in this embodiment includes the drive mechanism described above, and therefore includes at least all the beneficial effects of the drive mechanism described above, which will not be repeated here.

[0205] The above description is merely a preferred embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
