[0002] Cleaning robots, also known as automatic sweepers, smart vacuums, and robot vacuums, are smart home appliances that use artificial intelligence to automatically clean floors. They typically use a brushing and vacuuming method to collect debris into their own trash collection bins, completing the cleaning process. Generally speaking, robots that perform sweeping, vacuuming, and mopping are also categorized as cleaning robots.
[0003] The cleaning parts used in current cleaning robots are generally lifted off the ground or the surface of objects when they are not needed. However, due to the internal space limitations of existing cleaning robots, the height to which the cleaning parts can be lifted off the ground is limited, and the lifting height cannot meet the usage requirements in some application scenarios.

[0015] Furthermore, a traction block is fixedly provided on the side of the isolation member away from the fixed pulley, and a through hole is opened on the traction block for the traction rope to pass through. An abutment is provided on the second end, and the abutment abuts against the outer peripheral wall of the through hole.
[0016] Furthermore, a protrusion is provided at the bottom of the shell, and the protrusion is arranged opposite to the traction block along a first direction.

[0035] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.
[0036] In the description of this application, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.
[0037] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.
[0038] As a type of smart home appliance, cleaning robots are playing an increasingly important role in household cleaning due to their automation and intelligence. However, with the trend toward miniaturization of cleaning robots, the space inside the robots has been further compressed. This has resulted in the cleaning components used in current cleaning robots being limited in how high they can be raised and lowered from the ground when not in use. In some applications, this height cannot meet the required height.
[0039] Specifically, when the cleaning element is a wet cleaning module, traditional cleaning robots face a significant problem when cleaning carpets: how to effectively prevent the cleaning element from wetting the carpet. First, there are many types of carpets on the market, and their thickness ranges from a few millimeters to tens of millimeters. This thickness difference poses a challenge to the design of cleaning robots. Traditional cleaning robots usually use brushing and vacuuming to clean the floor, but for carpets, especially thicker carpets, simply relying on the cleaning element to rise to a height of about 10 mm is often unable to completely avoid contact between the cleaning element and the carpet, which may cause the carpet to get wet. The reason why the cleaning element can only rise 10 mm is due to the limitations of the robot's structural space. In addition, the material and water absorption of the carpet are also factors that need to be considered. Some carpet materials are easy to absorb water. Once the moisture on the cleaning element contacts the carpet, it is easy to leave water stains or stains, which not only affects the appearance, but may also cause damage to the carpet.
[0040] In view of the above technical difficulties, this embodiment provides a cleaning robot, such as Figures 1-11As shown, it includes: a shell 1, an isolation member 2, a cleaning member 3 and a power mechanism 4; the isolation member 2 is slidably installed at the bottom of the shell 1, has a first state and a second state, and can switch between the first state and the second state by overall horizontal sliding. In the first state, the isolation member 2 is located below the shell 1; in the second state, at least part of the isolation member 2 moves to the outside of the vertical space where the cleaning member 3 is located; the cleaning member 3 has a first position and a second position. When in the first position, the cleaning member 3 is located between the isolation member 2 and the shell 1; when in the second position, the cleaning member 3 is located below the isolation member 2. The power mechanism 4 is installed on the shell 1 and connected to the cleaning member 3. The power mechanism 4 can drive the cleaning member 3 to move between the first position and the second position.
[0041] Based on the above scheme, the cleaning robot's design cleverly combines an isolation member 2 with a power mechanism 4. Through precise mechanical and electronic control, it achieves flexible lifting and lowering of the cleaning member 3. This design specifically addresses the issue of preventing the cleaning member 3 from wetting the carpet during carpet cleaning, providing users with a more convenient and efficient cleaning experience. Its operating principle is as follows: The isolation member 2 is mounted on the bottom of the cleaning robot's housing 1 and can flexibly switch between a first state and a second state. When in the first state, the isolation member 2 tightly fits with the bottom of the housing 1, forming a relatively closed storage space. In this state, the cleaning member 3 is cleverly contained within this storage space, completely isolated from the floor and carpet, avoiding unnecessary contact and friction. The cleaning member 3 is tightly connected to the power terminal of the power mechanism 4. This tight connection can be either a direct connection between the cleaning member 3 and the power mechanism 4 or an indirect transmission connection. This is not specifically defined here and can be adjusted according to different design requirements in actual use. The cleaning member 3 is precisely driven by the power mechanism 4 to achieve reciprocating movement between the first and second positions. When mopping is required, the power mechanism 4 rapidly drives the cleaning element 3 to the second position, extending it from the storage space and making close contact with the floor for efficient and thorough cleaning. Crucially, when the cleaning robot intelligently detects a carpet, the isolation element 2 immediately remains in the first position, effectively sealing the storage space. Simultaneously, the power mechanism 4 swiftly responds, maintaining the cleaning element 3 in the first position, preventing it from extending and contacting the carpet, effectively preventing the embarrassing situation of the cleaning element 3 wetting the carpet.
[0042] The above solution brings significant beneficial effects: First, it effectively isolates the contact between the cleaning part 3 and the carpet. No matter how the thickness of the carpet changes, it can ensure that the cleaning part 3 will not wet the carpet, thereby significantly improving the cleaning effect and user satisfaction. Users no longer need to worry about the cleaning robot leaving water stains or stains on the carpet, and enjoy a cleaner and tidier home environment. Secondly, this design makes the cleaning robot more adaptable. It can handle carpets of various thicknesses and is no longer restricted by the lifting height of the cleaning part 3. This means that users do not need to adjust the settings of the cleaning robot or replace different cleaning modules according to the thickness of different carpets, greatly improving the convenience and flexibility of use. In addition, the structure of the cleaning robot is simple and reliable. Through the clever combination of the isolation part 2 and the power mechanism 4, the lifting and isolation functions of the cleaning part 3 are realized. This design is not only easy to manufacture and assemble, but also convenient for subsequent maintenance and use. Users can easily clean and maintain the cleaning robot, extending its service life. Finally, this design undoubtedly enhances the user experience, effectively avoiding the embarrassing situation of the cleaning unit 3 wetting the carpet. This allows users to use the cleaning robot with greater peace of mind and confidence. Users no longer need to worry about the cleaning robot causing unnecessary damage or stains on the carpet, and can focus more on enjoying a clean and comfortable home life. In short, with its unique design and excellent performance, this cleaning robot provides users with a more convenient, efficient, and worry-free cleaning experience.
[0043] It is worth mentioning that as long as the isolation member 2 is partially moved to the outside of the vertical space where the cleaning member 3 is located, it is in the second state. This includes at least two situations. The first is that the isolation member 2 moves to the outside of the vertical space where the shell 1 is located, that is, the isolation member 2 extends out relative to the outer edge of the shell 1; the second is that the isolation member 2 is still within the vertical space where the shell 1 is located, but is staggered with the vertical space where the cleaning member 3 is located. In this case, the isolation member 2 will not interfere with the lifting and lowering of the cleaning member 3.
[0044] Furthermore, the isolating member 2 is slidably mounted on the bottom of the housing 1 and is capable of sliding in a first direction to the first state, or sliding in a reverse direction to the second state. The sliding mounting mechanism allows the isolating member 2 to slide smoothly and stably along the preset first direction, thereby switching its state. Specifically, when the isolating member 2 slides in the first direction, it gradually fits tightly against the bottom of the housing 1, forming a relatively closed accommodation space. At this time, the isolating member 2 is in the first state, and the cleaning member 3 is safely accommodated in this accommodation space, isolated from the external environment. On the contrary, when it is necessary to release the cleaning member 3 for cleaning, the isolation member 2 will slide in a direction opposite to the first direction. As the sliding progresses, the accommodating space is gradually opened. When the isolation member 2 slides to the second state, the accommodating space is completely opened, and the cleaning member 3 can be moved from the first position to the second position, that is, the cleaning member 3 is extended and exposed to the outside. At this time, the cleaning member 3 can perform normal cleaning work under the drive of the power mechanism 4. This sliding installation design not only makes the switching operation of the isolation member 2 simple and quick, but also improves the overall stability and reliability of the cleaning robot. By precisely controlling the sliding distance and speed of the isolation member 2, it can be ensured that the cleaning member 3 can be accurately extended or retracted when needed, avoiding unnecessary friction or collision with surfaces that should not be contacted, such as carpets. By setting the isolation member 2 to slide horizontally, the space occupied by the isolation member 2 in the vertical direction is limited. Therefore, it can avoid significantly increasing the height size of the cleaning robot, making it easier for the cleaning robot to enter the bottom of low-bottomed furniture such as sofas and coffee tables for cleaning operations. Furthermore, the sliding installation facilitates maintenance and replacement of the isolation member 2. When the isolation member 2 becomes worn or damaged due to long-term use, the user can easily remove it from the bottom of the housing 1 for replacement or repair without having to disassemble the entire cleaning robot. This not only saves the user's time and energy, but also reduces maintenance costs.
[0045] It should be noted that when the cleaning member 3 is extended, the isolation member 2 needs to be promptly reset, that is, quickly switched from the second state to the first state, so that the cleaning member 3 is below the isolation member 2. The purpose of this design is to prevent the isolation member 2 from increasing the overall size of the cleaning robot when in the second state, causing collisions or affecting the movement. In addition, the power mechanism 4 can not only drive the cleaning member 3 to move between the first position and the second position, but also drive the cleaning member 3 to rotate relative to the first position, thereby achieving the cleaning purpose.
[0046] As an optional specific implementation scheme, a linkage structure is set between the cleaning member 3 and the isolation member 2, and the isolation member 2 is automatically reset through the linkage structure. When the cleaning member 3 extends downward from the storage space, the linkage structure is triggered, and the isolation member 2 automatically resets to the first state, and the cleaning member 3 is directly below the isolation member 2.
[0047] As another optional specific implementation scheme, the isolating member 2 can be switched in a folding manner. Simply put, the isolating member 2 is designed to be foldable in multiple layers in a first direction. When the isolating member 2 is folded in the opposite direction, the isolating member 2 switches to the second state, the accommodating space opens, and the cleaning member 3 can be extended; when the isolating member 2 is opened in the first direction, the isolating member 2 switches to the first state, and the accommodating space is closed again.
[0048] Based on the solution that the isolating member 2 is slidably installed at the bottom of the shell 1, in order to ensure that the isolating member 2 can slide accurately and smoothly along the predetermined path, a guide mechanism 6 is also included, and the guide mechanism 6 is connected between the isolating member 2 and the shell 1.
[0049] Specifically, the guide mechanism 6 includes a guide portion 601 provided at the bottom of the housing 1 and a guide groove 602 provided on the isolating member 2, wherein the guide groove 602 is in a guiding cooperation with the guide portion 601. The guide portion 601 is fixed to the bottom of the housing 1 of the cleaning robot, and is usually in an elongated strip or a specific shape to adapt to the sliding path of the isolating member 2. The surface of the guide portion 601 is finely processed to ensure its flatness and smoothness so as to achieve a smooth sliding cooperation with the guide groove 602 on the isolating member 2. The design of the guide portion 601 also takes into account wear resistance to cope with the wear problem caused by long-term sliding. The guide groove 602 is a key structure provided on the isolating member 2. It corresponds to the guide portion 601 at the bottom of the housing 1 to form a tight guiding cooperation. The shape and size of the guide groove 602 are precisely calculated and designed to ensure that the isolating member 2 can move stably along the predetermined direction during the sliding process. The sidewalls of the guide groove 602 have a certain elasticity or lubricity to reduce the friction between the guide portion 601 and improve the sliding efficiency. As the isolator 2 slides along the bottom of the housing 1, the guide groove 602 and the guide portion 601 form a tight, guiding fit. This fit ensures that the isolator 2 does not deviate from its intended path during sliding, thus preventing problems such as shaking, drifting, or getting stuck. This guiding fit also improves the smoothness and reliability of the isolator 2's sliding, providing a strong guarantee for the cleaning robot's overall performance.
[0050] Furthermore, three guide mechanisms 6 are provided, evenly spaced along the second direction. A traction assembly 5 is provided within the guide mechanism 6 located in the middle position. The traction assembly 5 is used to pull the isolator 2 repeatedly between the first state and the second state, wherein the second direction is in a plane perpendicular to the first direction. The layout of the three guide mechanisms 6 not only enhances the stability of the isolator 2 during sliding, but also ensures smooth switching between different states. A traction assembly 5 is specifically provided within the guide mechanism 6 located in the middle position. This assembly is the key driving force for the isolator 2 to repeatedly switch between the first state and the second state. The traction assembly 5 applies a certain traction or propulsion force to enable the isolator 2 to slide smoothly along the guide mechanism 6 to the desired position. Specifically, when the cleaning robot needs to perform a cleaning task, the control system issues a command to activate the traction assembly 5, which then starts up, generating traction or propulsion. This force acts on the isolator 2, causing it to slide along the guide mechanism 6 toward the second state until the cleaning element 3 is fully extended and contacts the ground, at which point the traction assembly 5 drives the isolator 2 back to its original position. When the cleaning task is completed or it is necessary to avoid the cleaning member 3 from contacting a specific surface (such as a carpet), the control system will issue an instruction again, and the traction component 5 will drive the isolation member 2 to switch to the second state, open the accommodating space, and the cleaning member 3 will be quickly reset to the accommodating space under the drive of the power mechanism 4, and then the traction component 5 will work in reverse. At this time, the force generated by the traction component 5 will guide the isolation member 2 to slide along the guide mechanism 6 to the first state, and the cleaning member 3 will be quickly and smoothly retracted into the accommodating space, thereby avoiding unnecessary contact with the external environment.
[0051] Furthermore, a fixed pulley 7 is provided at the bottom of the housing 1, and the fixed pulley 7 is disposed on one side of the guide portion 601. The traction assembly 5 traction motor 501 and traction rope 502 are installed in the housing 1. The traction motor 501 is installed in the housing 1, and the traction rope 502 includes a first end and a second end that are opposite to each other. The first end is connected to the traction motor 501, and the second end bypasses the fixed pulley 7 and extends along the direction of the guide slot 602 to connect with the isolation member 2. The fixed pulley 7 is installed on one side of the guide portion 601, and its position has been carefully calculated to ensure that the traction rope 502 can smoothly bypass and extend along the predetermined path. The main function of the fixed pulley 7 is to change the direction of the traction rope 502 so that it can act on the isolation member 2 along the direction of the guide slot 602, thereby achieving effective traction and resetting. The traction motor 501 is installed in the housing 1 of the cleaning robot and is responsible for providing driving force. The traction rope 502 serves as a transmission medium. Its first end is connected to the traction motor 501, and the rotational movement of the traction motor 501 generates tension or thrust. The second end bypasses the fixed pulley 7 and extends along the direction of the guide groove 602 to connect with the isolation member 2, thereby transmitting the power of the motor to the isolation member 2. When it is necessary to open the accommodating space and extend the cleaning member 3, the control system starts the traction motor 501. The traction motor 501 rotates to drive the first end of the traction rope 502 to move. Since the traction rope 502 bypasses the fixed pulley 7 and extends along the direction of the guide groove 602, an outward pulling force is generated. This pulling force acts on the isolation member 2, causing it to slide along the guide mechanism 6 to the second state until the cleaning member 3 is fully extended and in the working position.
[0052] At the same time, a traction block 8 is fixedly mounted on the side of the guide groove 602 facing away from the fixed pulley 7. The traction block 8 is provided with a through hole 801 through which the traction rope 502 passes. An abutment portion 503 is provided on the second end of the traction rope 502, and the abutment portion 503 abuts against the outer peripheral wall of the through hole 801. In this solution, the first end of the traction rope 502 passes through the through hole 801 of the traction block 8 in a first direction. During the traction process, the traction force generated by the traction rope 502 is effectively transmitted through the abutment portion 503 abutting against the outer peripheral wall of the through hole 801. That is, the traction rope 502 can effectively pull the isolation member 2 from the first state to the second state, thereby completing the opening of the accommodation space.
[0053] Furthermore, to achieve automatic reset of the isolator 2 (i.e., automatically switching to the first state), the guide portion 601 is provided with a protrusion 603. The protrusion 603 is arranged opposite the traction block 8 along a first direction. An elastic member 504 is disposed between the protrusion 603 and the traction block 8. The elastic member 504 ensures that the isolator 2 always has a tendency to switch toward the first state or the second state. The protrusion 603 and the traction block 8 form a relatively stable structure in space, providing a clear guide for the movement of the isolator 2. An elastic member 504 is cleverly installed between the protrusion 603 and the traction block 8. This elastic member 504 can be made of a material with restoring force, such as a spring or elastic sheet, and its function is to ensure that the isolator 2 always has a tendency to switch toward a certain direction (usually the first state or the second state). When the isolator 2 is in the unlocked state, the elastic force of the elastic member 504 acts on the isolator 2, pushing it to move in the predetermined direction.
[0054] During the automatic resetting process, when the traction motor 501 stops working and the traction rope 502 no longer applies traction to the isolation member 2, the elastic force of the elastic member 504 immediately takes effect. If the isolation member 2 is currently in the second state (cleaning member 3 extended state), the elastic member 504 will push the isolation member 2 to slide along the guide groove 602 to the first state until it is fully reset. Similarly, if the isolation member 2 deviates from the preset position for some reason, the elastic member 504 will quickly pull it back to the correct position. This design not only simplifies the reset mechanism of the isolation member 2, but also improves the intelligence level of the cleaning robot. Through the elastic force of the elastic member 504, the isolation member 2 can be automatically reset without manual intervention or continuous power input, which greatly improves the convenience and efficiency of use.
[0055] It should be noted that in order to prevent the protrusion 603 from affecting the insertion of the traction rope 502, a through groove 604 for the traction rope 502 to pass through needs to be opened on the protrusion 603. The design of this through groove 604 should take into account the diameter, material and movement trajectory of the traction rope 502 to ensure that it can pass through easily without friction or obstruction. The position and size of the through groove 604 should be accurately calculated to ensure that it does not interfere with the relative position relationship between the protrusion 603 and the traction block 8, nor does it affect the elastic force of the elastic member 504 on the isolation member 2. At the same time, the edges of the through groove 604 should be smoothed to reduce the wear or noise that may be generated when the traction rope 502 passes through. Through such a design, the effective insertion of the traction rope 502 is guaranteed, and the stability and reliability of the isolation member 2 during the automatic resetting process are guaranteed.
[0056] As another optional specific implementation scheme, the traction component 5 can adopt a double-stroke cylinder structure, the power end of the cylinder is connected to the isolation member 2, the cylinder can drive the isolation member 2 to move along the first direction to the second state, and can also drive the isolation member 2 to move in the opposite direction to the first state, which is equivalent to the cylinder being able to accurately control the isolation member 2 to switch repeatedly between the first state and the second state.
[0057] In some embodiments, the power mechanism 4 includes a power member 301 and a power shaft 302, the power member 301 is connected to the power shaft 302, the power shaft 302 is connected to the cleaning member 3, the power member 301 drives the power shaft 302 to move up and down, and then synchronously drives the cleaning member 3 to move back and forth between the first position and the second position, and the isolation member 2 is provided with a avoidance groove 202 corresponding to the power shaft 302. The power member 301 is the core of the entire power system and is responsible for providing the necessary driving force. It can be a motor, a cylinder or other device that can generate linear or rotational motion. The power member 301 is connected to the power shaft 302 by some connection method (such as gears, belts, connecting rods, etc.) to transmit power to the power shaft 302. The power shaft 302 is a key component connecting the power member 301 and the cleaning member 3. One end of the power member 301 is connected to the power member 301, and the other end is directly or indirectly connected to the cleaning member 3. When the power member 301 is activated, it drives the power shaft 302 to move along a predetermined trajectory (usually in the up and down direction). This movement will synchronously drive the cleaning member 3 to move accordingly, thereby realizing the switching of the cleaning member 3 between the extended and retracted positions.
[0058] To prevent interference between the isolator 2 and the power shaft 302 during the reset process, a special escape groove 202 is provided on the isolator 2, corresponding to the power shaft 302. The shape and size of this escape groove 202 are precisely calculated to ensure that the power shaft 302 can move within the escape groove 202 during the switchover from the second state to the first state. This ensures that the reset operation can be completed without any collision between the isolator 2 and the power shaft 302. Furthermore, the escape groove 202 and the power shaft 302 also serve as a guide, ensuring the stability and reliability of the isolator 2 during movement.
[0059] To better accommodate and protect the cleaning element 3 while ensuring smooth movement of the isolation element 2, a first arcuate groove 101 is cleverly designed on the bottom of the housing 1, while a corresponding second arcuate groove 201 is provided on the isolation element 2. The design of these two arcuate grooves is not only aesthetically pleasing but also highly functional. Specifically, the first arcuate groove 101, located at the bottom of the housing 1, has been carefully calculated in shape and size to match the shape of the cleaning element 3. This way, when the cleaning element 3 is installed in the accommodation space, it fits snugly within the contours of the first arcuate groove 101, providing stable support and positioning. The second arc groove 201 on the isolation member 2 corresponds to the first arc groove 101. When the isolation member 2 is in different positions (such as the cleaning member 3 is extended or retracted), the second arc groove 201 will form spaces of different shapes and sizes with the first arc groove 101. These spaces together constitute the accommodating space for the cleaning member 3. This accommodating space provides a safe and stable storage environment for the cleaning member 3, preventing the cleaning member 3 from accidentally falling off or being damaged during the operation of the cleaning robot.
[0060] Furthermore, the coordination between the first arcuate groove 101 and the second arcuate groove 201 ensures smooth movement of the isolator 2. Since the shapes and positions of the two arcuate grooves match each other, the isolator 2 will not encounter any unnecessary obstruction or friction when sliding along the guide mechanism 6. This design not only improves the efficiency of the cleaning robot but also extends the service life of the device.
[0061] It is worth mentioning that the cleaning member 3 is a rotatable mop. The rotatable mop can better fit the ground during operation, and can achieve effective cleaning whether it is smooth tiles and wooden floors or rough carpets or uneven floors. The rotating motion of the mop can increase the friction with the ground, thereby removing stains and dust more thoroughly.
[0062] In the specific application of the cleaning robot, two cleaning members 3 are provided, and one or two power mechanisms 4 can be designed according to actual needs. When two power mechanisms 4 are provided, the two cleaning members 3 work independently, and when one power mechanism 4 is provided, the two cleaning members 3 work synchronously. The two cleaning members 3 are arranged with the guide mechanism 6 in the middle as the center line to achieve maximum cleaning area coverage; and the isolation member 2 is specifically a cover plate, that is, the cover plate is movably matched with the housing 1. In addition, the cleaning robot also includes structural components such as the roller, universal wheels, and camera, which are not detailed here.
[0063] As an optional specific implementation scheme, specifically when the cleaning component 3 includes a wet cleaning module and a dry cleaning module, in simple terms, the wet cleaning module is used for mopping the floor, and the dry cleaning module is used for sweeping the floor. The wet cleaning module includes a rotatable circular mop 301, or a roller, or a flat mop, or an irregularly shaped rotating mop, wherein the irregularly shaped mop is specifically similar to a triangle in overall shape, but with rounded corners for smooth transition. The number of mops 301 can be one or two. The solution with two mops 301 is called a two-person mop in the cleaning robot industry terminology. The dry cleaning module includes a middle sweeping roller brush 302 that is rollingly mounted on the bottom of the shell 1, or a side brush that is rotatably mounted on the bottom of the shell 1, wherein the side brush can expand or retract relative to the shell 1.
[0064] For the above-mentioned cleaning member 3, the movement mode of the isolation member 2 includes the following situations: the first situation is that the isolation member 2 can isolate the wet cleaning module and the dry cleaning module at the same time; the second situation is to isolate only the wet cleaning module; the third situation is to isolate only the dry cleaning module.
[0065] Based on the first scenario, its actual application scenario is that when the cleaning robot moves to the designated cleaning area, it does not need to perform sweeping and mopping operations in the area it is traveling. In this case, the isolation member 2 needs to isolate the wet cleaning module and the dry cleaning module at the same time, so that both modules are separated from the ground or carpet. Alternatively, if there are many small objects that cannot be avoided in the cleaning robot's forward path, once the wet cleaning module and the dry cleaning module come into contact with these small objects, they may become entangled or rolled into the interior, causing unnecessary accidents. In this case, the isolation member 2 is required to effectively isolate the wet cleaning module and the dry cleaning module at the same time.
[0066] Based on the second situation, its actual application scenario is the same as the previous implementation scheme. When it is necessary to prevent the wet cleaning module from wetting the carpet, the wet cleaning module is effectively isolated by the isolation member 2, but there is no need to isolate the dry cleaning module. The dry cleaning module can effectively clean the carpet.
[0067] The third situation can be applied when only mopping the floor is needed but sweeping is not, or when mopping the floor is needed after sweeping. Generally speaking, it is when the dry cleaning module interferes with the cleaning action of the wet cleaning module. Specifically, when cleaning oil stains, water stains and other stains, the action of the dry cleaning module will cause the contamination area to expand, and the dry cleaning module will be contaminated. In this case, the dry cleaning module can be isolated by the isolation member 2, and it can also protect the dry cleaning module and avoid the dry cleaning module from getting stuck.
[0068] As another optional specific implementation scheme, when the cleaning component 2 is a dry cleaning module, there are many charging cables, ropes and other similar items in the space to be cleaned where the cleaning robot is located. Once the cleaning robot moves above these items, the dry cleaning module will inevitably come into contact with these items. Charging cables and other items cannot be easily cut like hair. Once they are entangled, it will inevitably cause the dry cleaning module or even the cleaning robot to malfunction. Even if the contact is avoided by controlling the lifting of the dry cleaning module, as mentioned above, due to space limitations, the lifting height is also limited, and contact cannot be completely avoided. Therefore, in this case, the isolation component 2 is covered under the dry cleaning module to achieve effective isolation, so that the dry cleaning module can be completely prevented from contacting the above-mentioned items; in addition, when the cleaning robot leaves the area, the isolation component 2 switches its state, allowing the dry cleaning module to continue cleaning.
[0069] On the other hand, a control method for a cleaning robot is also provided, which is specifically used in the above-mentioned cleaning robot. The control method includes: controlling the cleaning member 3 to move from the first position to the second position and controlling the cleaning member 3 to move from the second position to the first position; before the above-mentioned control of the cleaning member 3 to move, controlling the isolation member 2 to move to the second state; after the above-mentioned control of the cleaning member 3 to move, controlling the isolation member 2 to move to the first state.
[0070] In order to avoid interference between the isolation member 2 and the cleaning member 3 during the movement process, if the isolation member 2 moves first, it is necessary to ensure that the isolation member 2 moves into place, and then control the cleaning member 3 to move. When the cleaning member 3 also moves into place, finally control the isolation member 2 to move and reset.
[0071] At the same time, the control logic for the reciprocating movement of the cleaning member 3 between the first position and the second position is as follows: control the cleaning member 3 to move from the first position to the second position, after the isolation member 2 moves to the second state, or, during the process of the isolation member 2 moving to the second state, here when the isolation member 2 moves to the second state, that is, the isolation member 2 is not in the vertical space where the cleaning member 3 is located, which is equivalent to the isolation member 2 not interfering with the lifting and lowering of the cleaning member 3, and controlling the cleaning member 3 to move simultaneously during the movement of the isolation member 2, in this case it is necessary to ensure that the isolation member 2 does not block the movement of the cleaning member 3, it can be that when the cleaning member 3 starts to move, the positions of the isolation member 2 and the cleaning member 3 are completely staggered, or when the cleaning member 3 moves to the height where the isolation member 2 is located, the cleaning member 3 and the isolation member 2 are just completely staggered.
[0072] The cleaning member 3 is controlled to move from the second position to the first position, and this is performed after the isolating member 2 moves to the second state, or during the process of the isolating member 2 moving to the second state. The cleaning member 3 needs to move from the second position to the first position, specifically from the bottom to the top. When the cleaning member 3 is at the bottom, the isolating member 2 is located above the cleaning member 3. Therefore, it is necessary to first control the isolating member 2 to move to the second state, which is equivalent to the accommodating space being opened, and the cleaning member 3 can be lifted into the accommodating space. Then, the isolating member 2 is controlled to reset to the first state to isolate the cleaning member 3. The cleaning member 3 starts to move during the movement of the isolating member 2. In this case, reasonable dislocation is required to prevent the cleaning member 3 from hitting the isolating member 2 when it rises.
[0073] In addition, the reset control logic for the isolation member 2 is specifically as follows: while the cleaning member 3 is moving from the first position to the second position, the isolation member 2 is controlled to move to the first state, or, after the cleaning member 3 has completed its movement from the first position to the second position, the isolation member 2 is controlled to move to the first state; while the cleaning member 3 is moving from the second position to the first position, the isolation member 2 is controlled to move to the first state, or, after the cleaning member 3 has completed its movement from the second position to the first position, the isolation member 2 is controlled to move to the first state. To ensure that there is no interference, the preferred solution is to control the isolation member 2 to move to the first state and reset after the cleaning member 3 has moved into position, where the moving of the cleaning member 3 into position means that it has completely reached the first position or the second position. Of course, the movement and reset of the isolation member 2 can also be controlled during the movement of the cleaning member 3, but this movement control needs to be completed through precise parameter settings, such as how many seconds after the cleaning member 3 starts to move, the isolation member 2 starts to move, or the specific position of the cleaning member 3 is detected by setting a position sensor, and then the movement signal is sent through the position sensor to control the movement and reset of the isolation member 2; vice versa, that is, the specific position of the isolation member 2 is detected by the position sensor, and then the movement of the cleaning member 3 is triggered.
