Detailed Description

In order to enable those skilled in the art to better understand the present application, the following description will make clear and complete descriptions of the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.

It should be noted that, the descriptions of "first" and "second" herein are used to distinguish different messages, devices, modules, etc., and do not represent a sequence, and are not limited to the "first" and the "second" being different types. In addition, the embodiments described below are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

Fig. 1 is a schematic view of a first cross-sectional structure of a cleaning device according to an embodiment of the present application, fig. 2 is a schematic view of a second cross-sectional structure of a cleaning device according to an embodiment of the present application, and fig. 3 is a schematic view of a third cross-sectional structure of a cleaning device according to an embodiment of the present application.

Referring to fig. 1 to 3, embodiments of the present application provide a cleaning apparatus including: the apparatus body (not shown in the figures, only the bottom case 1 or chassis of the apparatus body is shown), the driving means (not shown in the figures), and the cleaning means 3. The cleaning device may include, but is not limited to, a sweeping robot, a sweeping and mopping integrated machine, and the like, and functions of the device body of different cleaning devices are different, for example, for an intelligent sweeping robot, the device body is a robot body and includes a chassis, a driving wheel, a control device, a cleaning system, an energy system, and the like. The intelligent sweeping robot can autonomously complete cleaning work under the condition of no human intervention. For another example, the semi-automatic cleaning apparatus includes a cleaning main body, an auxiliary wheel, a control device, an energy system, a control handle, etc., and the user controls the cleaning main body to perform cleaning work through the control handle.

The cleaning device further comprises a drive means 2, the drive means 2 being arranged on the device body. The driving device 2 can detach the cleaning device 3 and mount the cleaning device 3. Specifically, the driving device 2 is provided with an output shaft, and the cleaning device 3 is detachably connected to the output shaft. When the cleaning device 3 is connected to the driving device 2, the driving device 2 can transmit a driving force to the cleaning device 3; when the cleaning device 3 is disconnected from the driving device 2, the cleaning device 3 and the driving device 2 may be in contact or in a non-contact state, but the driving force of the driving device 2 cannot be transmitted to the cleaning device 3. The cleaning device 3 is used for cleaning a working surface, for example, the cleaning device 3 may be disposed below the bottom case 1 of the apparatus body, and may be used for wiping the surface to be cleaned by being in frictional contact with the surface to be cleaned, so as to implement a mopping operation. Alternatively, in other embodiments, the cleaning apparatus may comprise at least two cleaning devices 3, different cleaning devices 3 may fulfill different job requirements, for example: the first cleaning device can realize the floor mopping requirement, and the second cleaning device can realize the floor sweeping requirement. The cleaning device 3 may be a dishcloth or a roll brush or the like.

In the solution provided in the present application, the driving device 2 is capable of outputting driving forces in two different directions. More specifically, the driving forces in two different directions in the present embodiment include a rotational power in the first direction and a rotational power in the second direction. The driving device 2 outputs a rotational power in a first direction to be connected with the cleaning device 3, and the driving device 2 outputs a rotational power in a second direction such that the cleaning device 3 is disconnected from the driving device 2. The disconnection means that the driving device 2 is disconnected from outputting the driving force to the cleaning device, and the driving device 2 and the cleaning device 3 may be in contact or non-contact state in terms of structure. The first direction and the second direction are two different directions, for example, the first direction is a clockwise direction, and the second direction is a counterclockwise direction; the first direction is a counterclockwise direction, and the second direction is a clockwise direction, which is not limited in this embodiment. During connection or disconnection, there is a relative movement of the drive means and the cleaning means in the rotational axis direction. Specifically, during the connection of the driving device 2 and the cleaning device 3, the driving device 2 and the cleaning device 3 have a rotational force which moves axially in opposite directions. For example, the driving device 2 moves in a direction approaching the cleaning device 3. During the disconnection of the drive device 2 from the cleaning device 3, there is a rotational axial counter-movement of the drive device 2 and the cleaning device 3. For example, the drive means 2 is moved in a direction away from the cleaning means 3.

In addition, the specific form of the cleaning device 3 is different, and the orientation of the rotation axis of the rotation power output from the driving device is also different. For example, when the cleaning device is a dishcloth, the rotation axis of the rotation power output by the driving device is perpendicular to the dishcloth. When the cleaning device is a rolling brush, the rotating shaft of the rotating power output by the driving device is the rolling brush shaft.

The driving device in the present embodiment may be used only as a means for automatically detaching the cleaning device 3 by the cleaning apparatus. The cleaning device 3, such as a wipe, may be stationary, i.e. no relative movement with the body of the apparatus, and move with the body of the apparatus to clean a surface to be cleaned. In other possible embodiments, the driving device in this embodiment may be used to drive the cleaning device to perform a cleaning action, such as rotation relative to the apparatus body, linear reciprocation relative to the apparatus body, or the like, in addition to the device for automatically detaching the cleaning device 3 from the cleaning apparatus. If the cleaning device is a dishcloth, the driving device can continuously drive the dishcloth to rotate along the rotation power of the first direction after outputting the rotation power of the first direction to be connected with the dishcloth, so as to rub against a surface to be cleaned (such as a floor, a tabletop, a wall surface and the like) to clean the surface to be cleaned. Alternatively, the driving device is provided with two driving components, wherein one driving component is used for outputting the rotation power in the first direction and the second direction, and the other driving component is used for outputting the linear reciprocating motion so as to drive the cleaning device (such as rag) to linearly reciprocate.

In one embodiment provided in the present application, see fig. 1 to 3, the drive means 2 is arranged on the apparatus body, and the cleaning means 3 is connected to the apparatus body via the drive means 2. The driving device 2 can drive the cleaning device 3 to perform cleaning operation, and can connect or disconnect the cleaning device 3 to or from the apparatus body. In particular, the cleaning device 3 is a rotatable dishcloth which can be connected to the output shaft of the drive device 2. When the cleaning device 3 is in a non-connected state with the driving device 2 and the connection is aligned, the driving device 2 outputs the rotation power in the first direction, and the driving device 2 can be connected with the cleaning device 3 and drive the cleaning device 3 to rotate so as to execute the cleaning action. When the driving device 2 outputs the rotational power in the second direction in a state where the driving device 2 is connected to the cleaning device 3, the rotational power disconnects the driving device 3 from the driving device 2.

The driving device 2 in the embodiment of the present application may be a motor.

The technical scheme provided by the embodiment of the application is described in further detail below.

In the cleaning apparatus provided in the embodiments of the present application, referring to fig. 1 to 2, the cleaning device 3 is disconnected from the driving device 2, and at least part of the apparatus body acts in a direction away from the cleaning device 3. In the process of connecting the cleaning device 3 to the driving device 2, at least part of the apparatus body is moved in a direction approaching the cleaning device 3. As shown in fig. 2, the cleaning device 3 is disconnected from the driving device 2, and the body of the apparatus body is lifted in a direction away from the cleaning device 3, and the driving wheels of the apparatus body are always in contact with the floor. Alternatively, the cleaning device 3 is disconnected from the driving device 2, and the rear side of the body of the apparatus body is lifted in a direction away from the cleaning device 3, and the body of the apparatus body assumes an inclined posture.

Further, referring to fig. 1 to 5, in one embodiment provided herein, the cleaning device 3 is connected to the driving device 2 by a screw mechanism. The screw mechanism has a screw locking direction, when the rotation power output by the driving device 2 in the first direction is the same as the screw locking direction, the cleaning device 3 and the driving device 2 are in locking connection, and at least part of the equipment body acts in a direction approaching to the cleaning device 3 due to the action of the screw mechanism in the connection process. In addition, when the rotation power of the second direction output by the driving device 2 is opposite to the screw locking direction, the connection between the cleaning device 3 and the driving device 2 is disconnected, and at least part of the equipment body acts in a direction away from the cleaning device 3 during the connection, so that the cleaning device 3 is separated from the equipment body. The cleaning device 3 is connected with the driving device 2 through the screw mechanism, so that not only can the connection or separation of the cleaning device 3 and the driving device 2 be realized, but also the connection structure can be simplified, and the cleaning device 3 can be disassembled and assembled more conveniently.

Further, referring to fig. 3 to 9, the screw mechanism comprises a first structure 5 and a second structure 4, the first structure 5 being provided with an inner screw groove 51 and the second structure 4 being provided with an outer screw protrusion 41. One of the first structure 5 and the second structure 4 is arranged on the drive device 2 and the other is arranged on the cleaning device 3. In the example shown in fig. 3, the first structure 5 is arranged on the drive device 2 and the second structure 4 is arranged on the cleaning device 3. The first structure 5 or the second structure 4 can be connected to the driving device 2 or the cleaning device 3 respectively through a connecting structure, or can be integrated with the driving device 2 or the cleaning device 3. The driving device 2 outputs a rotational power in a first direction, which is the same as the screw locking direction, and the outer screw protrusion 41 is screwed into the inner screw groove 51, so that the cleaning device 3 is connected with the driving device 2. The driving means 2 outputs a rotational power in a second direction, which is opposite to the screw locking direction, and the outer screw protrusion 41 is screwed out of the inner screw groove 51, so that the cleaning means 3 is disconnected from the driving means 2.

For example, in one embodiment provided herein, the first structure 5 is provided on the drive device 2 and the second structure 4 is provided on the cleaning device 3. When the driving device 2 and the cleaning device 3 are in a non-connected state and the first structure 5 and the second structure 4 are aligned with each other, the driving device 2 outputs rotation power in the first direction, the outer spiral protrusion 41 is screwed into the inner spiral groove 51, after the outer spiral protrusion is completely matched with the inner spiral groove 51, the cleaning device 3 is connected to the driving device 2, and meanwhile, in the connecting process, the equipment body moves towards the direction approaching to the cleaning device 3 along with the action of the spiral mechanism. In addition, when the cleaning device 3 is connected with the driving device 2, the driving device 2 outputs the rotation power in the second direction, the outer spiral protrusion 41 will be screwed out of the inner spiral groove 51, and when the outer spiral protrusion is completely screwed out of the inner spiral groove 51, the cleaning device 3 will be disconnected with the driving device 2, and the cleaning device 3 will move away from the device body under the action of the spiral mechanism in the disconnection process, and be smoothly separated from the device body.

The first structure 5 may be an internal thread structure having an internal spiral groove and the second structure 4 may be an external thread structure having an external spiral protrusion. Alternatively, as shown in fig. 6 to 9, the first structure 5 has a plurality of butt joints 52 and a plurality of inner spiral grooves 51, and the plurality of inner spiral grooves 51 extend along spiral line segments from the corresponding butt joints 52. The first structure 5 is provided on the first robot assembly 100 as shown in fig. 8a and 9. Specifically, the first automatic attachment/detachment unit 100 includes a connection portion 501 connected to the driving device and a first automatic attachment/detachment portion 502. The connection portion 501 has a mounting hole through which a fastener can be connected to an output shaft of a driving device such as a motor. The first automatic attaching/detaching portion 502 has a cylindrical structure, and a first structure 5 is provided on an inner wall thereof. As shown in fig. 6 and 7, the second structure 4 may have a plurality of docking protrusions 42 respectively adapted to the plurality of docking ports 52, and a plurality of outer spiral protrusions 41; a plurality of outer helical protrusions 41 extend along the helical line segments from corresponding abutment protrusions 42, respectively. Wherein the plurality of outer helical protrusions 41 are capable of being cooperatively coupled with the plurality of inner helical grooves 51. The second structure 4 may be provided on the second robot assembly 200 as shown in fig. 6 and 7. Referring to fig. 6 and 7, the second automatic dismounting member 200 is a cylindrical structure, and the second structure 4 is provided on an outer wall of the cylindrical structure. When the first structure 5 and the second structure 4 are connected to each other, the plurality of docking protrusions 42 are firstly docked with the plurality of docking ports 52, respectively, and then the plurality of outer screw protrusions 41 are screwed into the plurality of inner screw grooves 51. For example, in the examples shown in fig. 6 to 9, the first structure 5 has three opposite interfaces 52 and three internal spiral grooves 51; the second structure 4 has three mating abutment projections 42 and three externally threaded projections 41. In addition, it should be noted that: in fig. 8a, in order to reveal the structure of the inner spiral groove 51, a part of the structure is treated, that is, the structure constituting the third butt joint 50 is removed. Fig. 8b shows a three-dimensional schematic view of the first robot assembly 100.

In a specific implementation, when the first structure of the device body corresponds to the second structure (for example, the cleaning device is parked to a parking position of the base station, and the parking position is provided with the cleaning device, and at this time, the position of the device body of the cleaning device corresponds to the position of the cleaning device), it is possible that the docking port and the docking protrusion are not corresponding to each other, and at this time, the driving device only needs to rotate by a small angle, so that docking can be automatically completed for the docking port and the docking protrusion. In another embodiment provided in the present application, the first structure 5 may also have only one docking port 52 and one inner spiral groove 51, the inner spiral groove 51 corresponds to the docking port 52 and extends along a spiral line segment, and the second structure 4 has only one docking protrusion 42 and one outer spiral protrusion 41 adapted to the docking port 52, and the outer spiral protrusion 41 corresponds to the docking protrusion 42 and extends along the spiral line segment. Wherein the outer spiral protrusion 41 can be mutually matched and connected with the inner spiral groove 51, and one outer spiral protrusion 41 and one inner spiral groove 51 are mutually matched and connected, so that the structure is simple; but the connection stability is inferior to that of a plurality of structures.

Referring to fig. 8b and 9, the inner spiral groove 51 may include a first groove surface 511 and a second groove surface 512, the first groove surface 511 extending along a spiral line segment, the second groove surface 512 including a first guide section 5121 and a first action section 5122 sequentially arranged along a spiral screwing direction. Referring to fig. 6 and 7, the outer screw protrusion 41 includes a first protrusion side 411 and a second protrusion side 412, the first protrusion side 411 is fitted with the first groove surface 511, and the second protrusion side 412 includes a second guide section 4121 and a second acting section 4122. Wherein the second guide section 4121 is adapted to the first guide section 5121 and the first action section 5122 interacts with the second action section 4122 such that the screw mechanism is in a locked state. When the outer screw protrusion 41 is screwed into the inner screw groove 51, first the first guide section 5121 interacts with the second guide section 4121 and functions as a guide, after which the first protrusion side 411 contacts and slides with the first groove surface 511, and finally when the outer screw protrusion 41 is completely screwed into the inner screw groove 51, the first acting section 5122 interacts with the second acting section 4122 and interconnects the outer screw protrusion 41 with the inner screw groove 51. Further, in order to facilitate the smooth screwing-in or unscrewing of the outer spiral protrusion 41 into or out of the inner spiral groove 51, the spiral line segment of the first groove surface 511 forms an angle with the end surface of the cleaning device 3, the angle α being in the range of [10 degrees, 60 degrees ], more specifically, α being [30 degrees, 45 degrees ]. In addition, the first acting segment 5122 may be a plane perpendicular to the cylindrical structural axis of the first automatic assembling and disassembling member 100, and the second acting segment 4122 may be a plane perpendicular to the cylindrical structural axis of the second automatic assembling and disassembling member 200.

Specifically, as shown in fig. 8b, at least some of the plurality of docking interfaces 52 are provided with docking guidance ramps 56. The abutment guide ramp 56 can also be understood simply as: chamfering the edge of the interface.

Further, referring to fig. 4 to 9, the first structure 5 is provided with a first abutting portion 92, and the second structure 4 is provided with a second abutting portion 91, and the first abutting portion 92 and the second abutting portion 91 can be in abutting engagement with each other. Specifically, in one embodiment provided herein, the first abutment 92 may be a cylindrical protrusion disposed inside the tubular structure of the first automatic assembling and disassembling member 100, and an axis of the cylindrical protrusion coincides with an axis of the tubular structure. The second abutting portion 91 is a hole (e.g., a blind hole) in the cylindrical structure of the second automatic assembling and disassembling member 200, and the axis of the hole coincides with the axis of the cylindrical structure.

In one embodiment provided in the present application, see fig. 6 to 11, the first structure 5 is arranged on the drive device 2 and the second structure 4 is arranged on the cleaning device 3, the bottom of the apparatus body being provided with a guiding groove 7 adapted to the second structure 4. Alternatively, the first structure 5 is arranged on the cleaning device 3 and the second structure 4 is arranged on the driving device 2, and the bottom of the device body is provided with a guiding groove 7 adapted to the first structure 5. The guiding groove 7 is mainly used for guiding the cleaning device 3 to be installed or detached, and is used for guiding the cleaning device 3 to slide to a fixed position during installation so as to facilitate the abutting joint of the first structure 5 and the second structure 4. For guiding the cleaning device 3 out of the apparatus body and away from the cleaning apparatus along the guiding groove 7 when detached.

Further, the apparatus body has a bottom case 1, and the bottom case 1 is recessed upward of the apparatus body to form a guide groove 7, and the bottom of the guide groove 7 is a slope inclined upward. As shown in fig. 11, the guide groove 7 has a groove bottom 71 and opposite groove side walls 72. The body is moved towards the cleaning device and is movable by the guide slot 7 to the first configuration opposite the second configuration.

The guide groove in this embodiment may have, but is not limited to, one of the following structural features:

the groove bottom of the guide groove extends obliquely upwards from the driving device to the edge of the equipment body;

the groove width of the guide groove near the driving device is smaller than the groove width at the edge of the equipment body;

the guide groove is provided with a straight section groove and a bell mouth groove, the notch of the straight section groove is connected with the small mouth end of the bell mouth groove, the direction from the driving device to the edge of the equipment body is from the driving device, and the notch of the straight section groove and the bell mouth groove are sequentially arranged.

The upper side is the direction indicated by the arrow in fig. 1, and the opposite upper side is the lower side indicated in fig. 1. The guide groove 7 extends from the edge of the bottom case 1 to the first structure 5 or the second structure 4. For example, in one embodiment provided in the present application, the bottom case 1 is provided with a through hole, and the power output shaft of the driving device 2 is connected to the cleaning device 3 through the through hole. In particular, a second structure 4 is provided at the end of the power take-off shaft of the drive device 2, which second structure 4 is interconnected with the first structure 5 through a through hole. The guide groove 7 extends from the edge of the bottom shell 1 to the second structure 4. Further, the guide groove 7 has a larger groove width near the edge of the bottom case 1 than near the second structure 4. The guiding groove may further comprise a straight groove at a section near the second structure 4, the groove width of the straight groove being equal to or slightly larger than the diameter of the second structure 4. The guide groove 7 may also have a flare groove (or a bucket groove) capable of improving the guide effect of the guide groove 7, for example, when the cleaning device 3 is deviated from the aligned position on the bottom chassis 1, since the bucket groove can expand the guide range and adjust the position of the cleaning device 3 during the guide, the cleaning device 3 will be gradually aligned to the aligned position on the bottom chassis 1 after the cleaning device 3 enters the guide groove 7 from the edge of the bottom chassis 1.

Or, the rear end of the bottom shell of the device body is tilted upwards to form an inclined plane as shown in fig. 3. What is needed here is that: the body of the cleaning device has a front end and a rear end in the direction of travel of the cleaning device. Most cleaning implement wipes are provided at the bottom of the rear end of the implement body.

Or still alternatively, the top surface of the second structure 4 is provided as an inclined surface, the low point of the inclined surface firstly contacts with the bottom shell of the equipment body in the process of advancing towards the cleaning device 3, and then the equipment body is continuously lifted up along the inclined surface machine body until reaching the butt joint position.

In one embodiment provided in the present application, referring to fig. 1 to 9, the driving wheel and the cleaning device on the cleaning apparatus are located on the same floor, and the height of the cleaning device 3 is greater than the distance between the bottom chassis 1 and the floor. The bottom of the guiding groove 7 is an inclined surface 43 which is inclined upwards, one side close to the through hole is approximately flush with the bottom surface of the bottom shell 1, the inclined surface 43 extends obliquely upwards from the bottom surface of the bottom shell 1, and the height of the inclined surface 43 close to the edge of the bottom shell 1 from the ground is larger than that of the cleaning device 3. In addition, the first structure 5 is connected to the cleaning device 3, the second structure 4 is embedded into the bottom shell 1 from one side of the bottom shell 1 and is connected to the output shaft of the driving device 2, and the end face of the second structure 4 is flush with the bottom shell 1. When the chassis is driven by the drive wheel to move towards the cleaning device 3, firstly the inclined surface 43 of the guide groove 7 abuts against the end surface edge of the first structure 5, and as the cleaning device 3 moves along the guide groove 7 towards the position of the second structure 4, the chassis is gradually lifted up due to the action of the inclined surface 43 of the guide groove 7. Then when the first structure 5 is aligned with the second structure 4, under the action of the gravity of the lifted chassis, the first structure 5 and the second structure 4 are abutted with each other, the driving device 2 outputs spiral power in the first direction, so that the second structure 4 rotates in the first direction, and the outer spiral protrusion 41 on the second structure 4 can be screwed into the inner spiral groove 51 on the first structure 5. In addition, when the cleaning device needs to disassemble the cleaning device 3, the driving device 2 outputs the rotation power in the second direction, so that the second structure 4 rotates along the second direction, the outer spiral protrusion 41 on the second structure 4 can be screwed out from the inner spiral groove 51 on the first structure 5, the second structure 4 is gradually far away from the first structure 5 in the screwing-out process, and meanwhile, the chassis is gradually lifted and deviates from the cleaning device 3. At this point the first structure 5 is disconnected from the second structure 4, and as the drive wheel drives the chassis to move in a direction away from the cleaning device 3, the cleaning device 3 will slide along the guide groove 7, and as the end edge of the first structure 5 slides along the inclined surface 43 of the guide groove 7, the lifted chassis will gradually drop, and eventually the cleaning device 3 will disengage from the cleaning apparatus.

In one embodiment provided herein, the cleaning apparatus further comprises a holding mechanism for providing a force to maintain the connection of the cleaning device 3 to the cleaning device 3, the force failing after the driving device 2 outputs the rotational power in the second direction. For example, the retaining mechanism may be a rugged structure disposed on the contact surfaces of the first action segment 5122 and the second action segment 4122, respectively, and when the first structure 5 is connected to the second structure 4, the rugged structures of the first action segment 5122 and the second action segment 4122 will engage with each other and make the connection more stable.

Alternatively, referring to fig. 1 to 9, in one embodiment provided in the present application, the holding mechanism is a magnetic mechanism, the connection relationship between the cleaning device 3 and the cleaning device 3 is held by a magnetic force, and the magnetic force gradually fails after the driving device 2 outputs the rotational power in the second direction. The magnetic mechanism is a magnet with two opposite magnetic poles, or a magnet and a connecting piece capable of being attracted magnetically, or an electromagnet and a connecting piece capable of being attracted magnetically. When the two magnetic bodies are close enough, the two magnetic bodies attract each other, and when the distance exceeds a certain range, the magnetic acting force gradually disappears. For example, the first magnet 81 is disposed on the first structure 5, the second magnet 82 is disposed on the second structure 4, and after the first structure 5 is connected to the second structure 4, the distance between the magnets is sufficiently close, and the magnetic force will make the connection between the first structure 5 and the second structure 4 more stable. After the driving device 2 outputs the rotation power in the second direction, the first structure 5 and the second structure 4 are gradually separated from each other, so that the magnetic acting force gradually fails. When the magnetic body is an electromagnet, the electromagnet can be magnetized or the magnetism of the electromagnet can be vanished by switching off the power-on circuit of the electromagnet.

Or, the holding mechanism is an elastic mechanism, and the elastic mechanism comprises an elastic piece and a clamping structure, wherein one of the elastic piece and the clamping structure is arranged on the driving device 2, and the other of the elastic piece and the clamping structure is arranged on the cleaning device 3, and is used for clamping the elastic piece into the clamping structure to maintain the connection relation between the cleaning device 3 and the cleaning device 3 through clamping force when the driving device 2 is connected with the cleaning device 3; after the driving device 2 outputs the rotation power in the second direction, the elastic piece deforms and is separated from the clamping structure, and the clamping force fails.

The above embodiment provides an automatic disassembly and assembly of the cleaning device by controlling the driving device to output power in different directions. In addition, the cleaning device can be automatically assembled and disassembled by arranging an automatic assembling and disassembling mechanism on the device body. For example, in one embodiment of the present application, there is also provided a cleaning apparatus including an apparatus body, a cleaning device 3, and an automatic dismounting mechanism. The cleaning device 3 is detachably arranged on the equipment body; the automatic dismounting mechanism is arranged on at least one of the equipment body and the cleaning device and is used for disconnecting the cleaning device 3 from the equipment body and connecting the equipment body of the cleaning device 3 when the separated equipment body and the cleaning device 3 are in a butt joint position.

In this embodiment, the device body may be provided with a detachable guide structure; the equipment body moves towards the cleaning device and moves to be in the abutting position with the cleaning device under the action of the dismounting guide structure.

As in the embodiments described above, the dismounting guide structure is a guide groove provided at the bottom of the apparatus body; the guide groove extends from the edge of the equipment body to the automatic dismounting mechanism. The specific implementation of the guide groove can be seen from the above description, and the description is omitted here.

When another scheme is realized, the disassembly and assembly guiding structure is a convex track arranged at the bottom of the equipment body, and correspondingly, the cleaning device is provided with a chute block matched with the convex track. The protruding track at the bottom of the equipment body can be inserted into the chute of the chute block to play a guiding role.

The automatic disassembly and assembly mechanism can have the following realization schemes:

the first scheme is that the automatic dismounting mechanism comprises an electromagnet and a butt joint piece which can be attracted magnetically. Wherein, the electro-magnet can be set up on the equipment body, and the butt joint piece can be set up on cleaning device. In a specific embodiment, for example, an electromagnet is arranged on the drive 2. The driving device 2 may output rotational power or rectilinear reciprocation to drive the cleaning device to perform a cleaning action. The electromagnet is electrified and magnetized, a power output shaft of the driving device 2 is connected with a power access end of the cleaning device 3 under the action of magnetic force, and the driving device 2 outputs rotary power in a first direction to drive the cleaning device 3 to execute cleaning action. When the cleaning device 3 needs to be detached from the driving device 2, the magnetic property disappears by only disconnecting the energizing circuit of the electromagnet, and the cleaning device 3 is disconnected from the driving device 2. Specifically, a control device is arranged on the equipment body, and the electromagnet is electrically connected with the control device through a control circuit and is electrically connected with a power supply circuit of the equipment body. The control device sends a cutting-off instruction to the control circuit, the control circuit acts to cut off the electric connection between the electromagnet and the power supply circuit, and the electromagnet is powered off and the magnetic force disappears. The control device sends an opening instruction to the control circuit, and the control circuit acts to electrically connect the electromagnet with the power supply circuit, so that the electromagnet generates magnetism.

In a second aspect, referring to fig. 6 to 9, the automatic disassembling and assembling mechanism may include a driving device and a screw mechanism, where the screw mechanism includes a first structure 5 and a second structure 4. The first structure 5 is provided with an inner spiral groove 51 and the second structure 4 is provided with an outer spiral protrusion 41. Wherein one of the first structure 5 and the second structure 4 is arranged on the driving device 2 and the other is arranged on the cleaning device 3; the driving device 2 outputs a rotational power in a first direction, and the outer screw protrusion 41 is screwed into the inner screw groove 51, so that the cleaning device 3 is connected with the driving device 2. The driving means 2 outputs the rotation power in the second direction, and the outer spiral protrusion 41 is screwed out of the inner spiral groove 51, so that the cleaning means 3 is disconnected from the driving means 2. For a specific implementation of the second aspect, reference may be made to the above description, which is not repeated here.

The third scheme the automatic dismounting mechanism comprises a telescopic assembly, the telescopic assembly is arranged on the equipment body and comprises a telescopic rod, and the cleaning device is provided with a connecting structure matched with the end part of the telescopic rod. When the telescopic rod of the telescopic assembly is in a retracted state, the cleaning device is disconnected with the equipment body, and when the telescopic rod is in an extended state, the telescopic rod is connected with the connecting structure, so that the cleaning device is connected with the equipment body. In particular, the retraction assembly may include a linear power take off. The linear power output device may be realized by a linear motor, or a rotary motor+a linear power conversion mechanism (screw-nut mechanism), which is not limited in this embodiment. The linear power output device outputs linear power in a third direction, the telescopic rod is in a retracted state, and the cleaning device is disconnected with the equipment body; the linear power output device outputs linear power in a fourth direction, the telescopic rod is in an extending state, and the telescopic rod is connected with the connecting structure, so that the cleaning device is connected with the equipment body. The linear power in the third direction may be upward power (see the power pointed by the upper arrow in fig. 1), and the linear power in the fourth direction may be downward power (see the power pointed by the lower arrow in fig. 1).

In the third aspect, the telescopic rod and the cleaning device may not be fixed in the upward and downward directions as shown in fig. 1. The cleaning device is arranged on the surface to be cleaned, the end part of the rod of the telescopic rod is inserted into the jack of the connecting structure, and the cleaning device can move along with the equipment body so as to clean the surface to be cleaned (such as the ground). Further, at least one key can be arranged in the cross section direction of the telescopic rod; the connecting structure can be a jack, and key grooves matched with the keys are formed in the hole walls of the jack. Thus, the cleaning device according to the present embodiment may further include a driving device that outputs rotational power to the cleaning device through the key on the telescopic link and the key groove on the cleaning device, so that the cleaning device can rotate relative to the apparatus body.

The fourth scheme is that the automatic dismounting mechanism comprises an elastic clamp arranged at the bottom of the equipment body, a clamping part (such as a column body) matched with the elastic clamp is arranged on the cleaning device, and a connecting part for butting an output shaft of the driving device is arranged at the top of the column body. The connecting portion may be a connecting post provided at the top of the post body, the diameter of which is larger than that of the post body. The top of spliced pole is equipped with the recess, and the recess has the opening that is convenient for drive arrangement's output shaft to insert. The driving shaft is provided with a key, and a key groove is arranged on the opposite side of the groove to the notch. In the process that the equipment body moves towards the cleaning device, the elastic clamp is jacked up by the clamping part, the clamping part is clamped by the elastic clamp after the elastic clamp is opened and enters the elastic clamp, meanwhile, the driving shaft of the driving device enters the groove from the notch, and the key on the driving shaft is inserted into the key groove, so that the connection between the cleaning device and the driving device is completed. In practice, the cleaning device may be disposed in a tray of the base station and placed in a desired orientation.

When the cleaning device is disassembled, the cleaning device moves to the base station and stops at the stop position of the base station, the elastic clamp can be controlled to be opened in an electric control mode, and the cleaning device and the driving device are disconnected. Alternatively, the cleaning device is caught on the tray, and the connection of the cleaning device and the driving device may be disconnected only by the traveling power of the cleaning apparatus. Namely, in the process that the cleaning equipment leaves the base station, as the cleaning equipment is blocked on the tray and is opposite in two directions, the elastic clamp on the equipment body of the cleaning equipment deforms, the clamping part on the cleaning device is separated from the elastic clamp, and the output shaft of the driving device is separated from the notch, so that the disassembly of the cleaning device is completed.

The fifth scheme is that the automatic dismounting mechanism comprises an automatic clamping assembly and an elastic clamping piece, wherein the automatic clamping assembly is arranged on the equipment body, and the elastic clamping piece is arranged on the cleaning device. For example, after the device body moves towards the cleaning device and the elastic clamping piece on the cleaning device contacts the guide groove of the device body, the elastic deformation is pressed down, and when the belt device body moves to be in a butt joint position with the cleaning device, the elastic clamping piece is bounced to be clamped into the automatic clamping assembly, so that the connection between the device body and the cleaning device is completed. When the cleaning device is disassembled, the automatic clamping assembly on the device body acts to push out the elastic clamping piece under the control of the control device on the device body, namely, the cleaning device is disconnected with the device body. The structure of the automatic clamping assembly and the elastic clamping piece is not limited in this embodiment.

The application can also provide cleaning equipment with simple structure and easy realization. The cleaning device comprises a device body and a cleaning device. The equipment body is provided with a disassembly and assembly guiding structure. The equipment body moves towards the cleaning device and is connected with the equipment body when the equipment body moves to be in a butt joint position with the cleaning device under the action of the dismounting guide structure.

The specific implementation structure of the disassembly guiding structure can be referred to the above description, and will not be repeated here. When the equipment body and the cleaning device are in a butt joint position, the equipment body and the cleaning device can be connected in a mode that an electromagnet arranged on the equipment body generates magnetic attraction to magnetically attract a butt joint piece which can be magnetically attracted on the cleaning device; the telescopic component can be controlled to act through the control device on the equipment body, so that the telescopic rod is in an extending state to be connected with the connecting structure on the cleaning device, and the cleaning device is connected with the equipment body; etc. (see schemes above).

The application also provides a cleaning device. The cleaning device comprises a device body and a cleaning device. The device body is located on a plane (i.e. on the surface to be cleaned); the cleaning device is detachably connected to the equipment body. The equipment body has the function of automatically disassembling the cleaning device, the equipment body is used for disassembling the cleaning device, the cleaning device is positioned on the plane, and the equipment body acts in a direction away from the cleaning device. The present embodiment defines only the process of disassembling the cleaning device from the apparatus body, and the states of the apparatus body and the cleaning device, and does not limit the specific implementation of the structure that produces the above-described disassembling process. Wherein some of the above solutions may result in a disassembly process as defined in the present embodiment.

Further, in this embodiment, the apparatus body is provided with a lifting body and a supporting member, for example, the lifting body of the apparatus body is connected with the cleaning device in a manner similar to a magic hook and loop. The device body can lower the liftable body when being in a butt joint position with the cleaning device, so that the liftable body is in contact with the cleaning device, and the connection between the liftable body and the cleaning device is completed. When the cleaning device is disassembled, the propping piece stretches out or the propping piece and the liftable body descend simultaneously, the propping piece props against the cleaning device to enable the cleaning device to be located on a plane and not move, and the liftable body ascends, so that the liftable body is convenient for the cleaning device to disconnect. The propping piece rises after the liftable body is disconnected with the cleaning device. Or after the liftable body rises for a set distance, the propping piece rises again. In this embodiment, the set distance is not limited, for example, the lifting height of the liftable body is h, and the set distance may be greater than or equal to h/2.

The following should be added: the above-described aspects (e.g., aspect one, aspect three to aspect five) do not provide corresponding structural drawings. The reason for this is that: the specific implementation structure of each scheme is not limited in the application, so long as the structure, the components and the assemblies can realize the functions described above.

The cleaning apparatus provided by the embodiments of the present application are described above from a structural perspective. The scheme provided in the present application will be explained from the method point of view.

Further, the method provided by the embodiment of the application may further include the following steps:

103. generating a trigger event for detaching the cleaning device in response to a first instruction input by a user through the interaction device; or alternatively

104. Detecting a cleaning plane of the cleaning device, and generating a triggering event for disassembling the cleaning device when the cleaning plane is detected to be a set type plane.

Such as user operation or control of voice on interactive means (e.g., control panel, touch screen, voice control module, etc.) on the cleaning device. Or the cleaning device is connected with the intelligent terminal, and the user sends a first instruction to the cleaning device through the intelligent terminal.

The above-mentioned detection of the cleaning plane may be a type of material of the detection plane. The setting type may be a carpet type or the like. Or the types of surfaces to be cleaned can be simply divided into two types, one type being a surface that is not suitable for the type of mopping. One type is a plane suitable for the type of mopping. For example, if it is detected that the cleaning surface is a surface not suitable for a mopping type (e.g., a carpet surface), then the wipe or the roll brush (i.e., the cleaning device) may be removed. Upon detection of the cleaning device being a suitable mop type of surface to be cleaned, the event of installing the cleaning device can be triggered as the cleaning device is moved back and forth from the carpet surface to the wood floor or tile floor.
