[0030] One embodiment of the present application is described below in conjunction with the drawings, and it should be understood that the embodiment described herein is only used to illustrate and explain the present application, and is not used to limit the present application.

[0031] The embodiment of the first aspect of the present application provides a cleaning device, wherein the cleaning device can be a robot vacuum cleaner, a robot mop, a robot mop, or other cleaning devices that meet the requirements.

[0032] Specifically, the cleaning device includes but is not limited to: device main body, sensing system, control system, driving system, cleaning system, energy system and man-machine interaction system, etc. The above-mentioned various systems are coordinated with each other, so that the cleaning device can move autonomously to realize the cleaning function. The functional elements constituting the above-mentioned systems in the cleaning device are integrally arranged in the device main body. It can be understood that the cleaning device can be a self-moving cleaning device, wherein the self-moving cleaning device is a device that automatically performs cleaning operation in a certain cleaning area without user operation.

[0033] The embodiment of the second aspect of the present application provides a cleaning system. Wherein, the cleaning system includes a base station, the base station is used in cooperation with the cleaning device.

[0034] Specifically, when the cleaning device starts to work, the cleaning device starts from the base station to perform the cleaning task. When

[0035] The base station charges or performs other operations, such as water replenishment, and / or cleaning, and / or dust collection, etc.

[0036] Referring to FIGS. 1 and 2, the embodiment of the first aspect of the present application, the cleaning device includes an airflow driving assembly 1 and a fluid storage device 2, the airflow driving assembly 1 and the fluid storage device 2 are stacked vertically, and the fluid storage device 2 is detachably arranged on the side of the airflow driving assembly 1 close to the surface to be cleaned.

[0037] It should be noted that the airflow driving assembly 1 and the fluid storage device 2 are arranged in a vertically stacked manner, which greatly saves the horizontal and vertical space compared with the traditional front-back or left-right layout, simplifies the internal structure of the cleaning device, improves the utilization rate of the internal space of the cleaning device, reduces the overall volume of the cleaning device, and enables it to work flexibly and store conveniently in narrow space.

[0038] The cleaning device can be a robot vacuum cleaner, a robot mop, a robot sweeper and mop, or other devices that meet the requirements and automatically perform cleaning operations in a certain cleaning area without user operation.

[0039] Specifically, the cleaning device includes but is not limited to a perception system, a driving system, a cleaning system, an energy system, a human-computer interaction system, etc. The functional elements of the above-mentioned systems are integrally arranged in the device body, and are coordinated with each other, so that the cleaning device can move autonomously to realize the cleaning function.

[0040] In this embodiment, the cleaning device is a robot sweeper and mop, and its cleaning system covers a sweeping assembly and a mopping assembly. The sweeping assembly includes an edge brush on one side of the robot sweeper and mop, which is used to sweep dust, debris, etc. from the corners and the wall to the bottom of the machine; a main brush 4 at the bottom of the robot sweeper and mop, which is responsible for concentrating and rolling the garbage into the dust collection channel; and a dust collection fan that generates suction to suck dust and small particle garbage on the ground into the dust collection box 3. The mopping assembly includes a mop that directly contacts the surface to be cleaned to wipe stains and water stains; a water tank that provides water required for wetting the mop; and a pressurizing device that applies a certain pressure to the mop to enhance the mopping effect. It can be understood that the surface to be cleaned can be a floor or a carpet, etc. When the robot sweeper and mop walks on the surface to be cleaned, the sweeping assembly can realize dry cleaning, and the mopping assembly can realize wet cleaning.

[0041] It should be noted that in this embodiment, the airflow driving assembly 1 is part of the sweeping assembly, and the airflow driving assembly 1 includes a wind-driven unit 11, which is specifically a fan, for generating a suction gas passing through the dust collection box 3 to suck the garbage swept up by the main brush 4 into the dust collection box 3; the fluid storage device 2 is part of the mopping assembly, and the fluid storage device 2 is specifically a water tank for distributing cleaning fluid on at least a part of the width of the mop and the surface to be cleaned to wet at least a part of the mop.

[0042] The airflow driving assembly 1 and the fluid storage device 2 are arranged inside the device body of the cleaning device and are distributed vertically.

[0043] Specifically, in the embodiment, the air flow driving assembly 1 is located at the upper part of the device body, and the fluid storage device 2 is located at the lower part of the device body. That is, the air flow driving assembly 1 and the fluid storage device 2 are in a vertically stacked relationship, wherein the air flow driving assembly 1 is above and the fluid storage device 2 is below. It should be noted that the air flow driving assembly 1 and the fluid storage device 2 are vertically stacked, which greatly saves the horizontal and vertical space compared with the traditional front-back or left-right layout, simplifies the internal structure of the device body, improves the utilization rate of the internal space of the device body, reduces the overall volume of the cleaning device, and enables it to be flexible in narrow spaces and convenient to store; at the same time, it is also conducive to optimizing the center of gravity distribution of the cleaning device. When the air flow driving assembly 1 is above and the fluid storage device 2 is below, the cleaning device can be more stable during operation, especially when moving quickly, turning or crossing some small obstacles, reducing the risk of tipping over.

[0044] In the above embodiment, referring to FIGS. 1 and 2, the air flow driving assembly 1 includes a wind-driven unit 11 and an air duct 12, the air duct 12 is connected in communication with the air inlet end of the wind-driven unit 11, and at least part of the surrounding wall of the air duct 12 close to the fluid storage device 2 constitutes part of the container wall of the fluid storage device 2.

[0045] Among them, the air duct 12 is located inside the device body, used to connect the wind-driven unit 11 and the dust collection box 3 and other components, to guide the flow of air flow, and ensure that the suction force generated by the wind-driven unit 11 can be effectively transmitted to the dust collection box 3 and other dust collection accessories, so as to suck the dust, debris and the like on the surface to be cleaned.

[0046] Among them, the air flow driving assembly 1 and the fluid storage device 2 are arranged in a vertically stacked manner, specifically, the air duct 12 and the fluid storage device 2 are in a vertically stacked form.

[0047] Specifically, in the embodiment, the fluid storage device 2 is arranged between the air duct 12 and the bottom surface of the device body, and at least part of the surrounding wall of the air duct 12 close to the fluid storage device 2 serves as part of the top wall of the fluid storage device 2, which can effectively save the internal space of the device body, make the overall structure more compact, and help to reduce the volume of the cleaning device. At the same time, this combination enhances the integration level of the internal structure of the cleaning device, reduces the number of independent components, and reduces the complexity and cost of assembly.

[0048] It should be noted that when the fluid storage device 2 is arranged between the air duct 12 and the bottom surface of the device body, the airflow channel in the air duct 12 is relatively clear and regular due to the space occupied by the fluid storage device 2. The airflow flows in a relatively limited and regular space, and the conditions for chaotic airflow intersection and vortex formation are not easy to occur, reducing the suction fluctuation caused by vortex flow, so that the suction remains relatively stable during operation, ensuring the quality consistency of cleaning work. At the same time, the airflow flows smoothly, the wind resistance is reduced, and the wind-driven unit 11 does not need to consume too much energy to overcome the resistance, thereby reducing the overall energy consumption of the cleaning device and prolonging the battery endurance time. At the same time, the stable and regular airflow flow can reduce the noise generated by airflow turbulence and vortex formation, making the cleaning device run more quietly. At the same time, it avoids the local excessive pressure or airflow impact that may be caused by vortex flow, reduces the wear and damage to the air duct 12 and related parts, and prolongs the service life of the cleaning device.

[0049] Among them, the fluid storage device 2 is detachably arranged between the air duct 12 and the bottom surface of the device body.

[0050] Specifically, as one embodiment, a slide rail is arranged on the bottom surface of the device body relative to the mounting position of the fluid storage device 2, and the fluid storage device 2 is mounted and detached by sliding on the slide rail; as another embodiment, a magnet is installed on the bottom surface of the device body relative to the mounting position of the fluid storage device 2, and the fluid storage device 2 is fixed by magnetic force and can be detached by pulling.

[0051] It should be noted that the detachable fluid storage device 2 is convenient for users to take out separately for cleaning, removing internal dirt and impurities, and maintaining the cleanliness of the storage device, which helps to maintain the quality of the fluid and the cleaning effect. At the same time, when the wet cleaning function is not needed, the fluid storage device 2 can be detached to save the internal space of the device body and reduce the weight of the cleaning device.

[0052] In some possible implemented embodiments provided in the present application, the wind-driven unit 11 is arranged obliquely.

[0053] Among them, the oblique arrangement of the wind-driven unit 11 can be understood as that the mounting position of the wind-driven unit 11 is not completely horizontal or vertical, but forms a certain angle with the horizontal or vertical reference plane of the cleaning device.

[0054] Specifically, the axis of the wind-driven unit 11 can have a certain inclination angle relative to the chassis plane or the forward direction of the cleaning device. The inclination can be forward inclination, backward inclination, left or right inclination. In the present embodiment, the overall posture of the wind-driven unit 11 is inclined backward relative to the forward direction of the cleaning device.

[0055] It should be noted that the overall posture of the wind-driven unit 11 is inclined backward relative to the forward direction of the cleaning device, which can better arrange the layout of the wind-driven unit 11 and other components in the limited internal space of the device body, improve the space utilization, and make the structure of the cleaning device more compact.

[0056] In some possible implementation embodiments provided in the present application, referring to FIG. 2, the air duct 12 is in a straight line type or has a bending structure with no more than one smooth transition.

[0057] Here, the air duct 12 in a straight line type can be understood as that the air duct 12 is straight from one end to the other end without any bending or turning.

[0058] Here, the air duct 12 having a bending structure with no more than one smooth transition can be understood as that the air duct 12 can have a bending, but at most only one bending, and the bending is not a sudden, sharp corner, but a carefully designed smooth transition. For example, the air duct 12 can have a slow and smooth arc bending at a certain position to adapt to the spatial layout or functional requirements inside the device body.

[0059] It should be noted that the air duct 12 in a straight line type or having a bending structure with no more than one smooth transition can maximize the reduction of the resistance encountered by the airflow when flowing in the air duct 12, so that the suction force generated by the wind-driven unit 11 can be more effectively transmitted to the dust collection box 3, thereby improving the dust collection efficiency. At the same time, it helps to maintain the stability of the airflow, reduce the turbulence and vortex of the airflow, and make the suction force more uniform and continuous. At the same time, the reduction of wind resistance and the stability of airflow can reduce the noise generated by airflow turbulence, so that the cleaning device can work more quietly. At the same time, the reduction of wind resistance can reduce the energy consumption of the wind-driven unit 11, prolong the working time of the cleaning device or complete more cleaning tasks under the same power. At the same time, the relatively simple shape of the air duct 12 is not easy to accumulate dust and debris, which is convenient for later cleaning and maintenance, and keeps the air duct 12 unobstructed. At the same time, such a relatively simple air duct 12 structure helps to reasonably arrange the layout in the limited internal space of the device body, leaving more installation space for other components.

[0060] In some possible implementation embodiments provided in the present application, referring to FIG. 2, the air duct 12 has a passing area gradually decreasing along the flow direction.

[0061] Here, the air duct 12 is the channel for the airflow to flow in the device body. The flow direction refers to the path direction of the airflow flowing in the air duct 12. The passing area gradually decreasing along the flow direction means that from the air inlet of the air duct 12, as the airflow advances along the air duct 12, the cross-sectional area of the air duct 12 in the airflow flow direction gradually decreases.

[0062] Specifically, the air inlet of the air duct 12 is in communication with the dust collecting box 3, and the air outlet of the air duct 12 is in communication with the air driving unit 11. When the air driving unit 11 is working, the suction force generated thereby is transmitted to the dust collecting box 3 through the air duct 12. That is, the cross-sectional area of the air duct 12 gradually decreases in the direction from the dust collecting box 3 to the air driving unit 11.

[0063] It should be noted that, as the cross-sectional area of the air duct 12 gradually decreases, the air flow rate will increase accordingly according to the continuity principle. Higher air speed helps to improve the dust collection capacity and more effectively suck dust and debris into the dust collecting box 3. Meanwhile, the accelerated air flow rate can generate stronger suction force, which has better effect on adsorbing heavier or more tightly adhered dirt. Meanwhile, the stronger suction force can more quickly and completely collect dust and debris, reducing the omission in the cleaning process. Meanwhile, it helps to compress the sucked air flow, collect more dust and debris in the same volume, and improve the containing efficiency of the dust collecting box 3. Meanwhile, the flow state of the air flow can be adjusted to be more stable, reducing the generation of turbulence and vortex, thereby reducing noise and energy loss. Meanwhile, the cross-sectional area of the air duct 12 gradually decreases along the flow direction, which can better adapt to the complex space layout inside the device body and realize better performance of the air duct 12 in limited space.

[0064] In some possible implementation examples provided by the present application, referring to FIGS. 1 and 2, the cleaning device further comprises a dust collecting box 3 and a main brush 4, the main brush 4 is carried on the bottom of the cleaning device, and the dust collecting box 3 is arranged adjacent to the fluid storage device 2. The dust collecting box 3 comprises a dust suction port 31 and an air outlet 32, the dust suction port 31 is arranged towards the main brush 4, and the air outlet 32 is in communication with the air duct 12.

[0065] In the above embodiment, referring to FIGS. 1 and 2, the cross-sectional area of the dust suction port 31 is greater than that of the air outlet 32.

[0066] Specifically, the dust suction port 31 of the dust collecting box 3 is arranged towards the main brush 4, so that when the main brush 4 rotates for cleaning, dust and debris can be directly swept to the dust suction port 31, so that the dust and debris are quickly sucked into the dust collecting box 3. The air outlet 32 of the dust collecting box 3 is in communication with the air duct 12, so that the air flow can smoothly enter the air duct 12, and then under the action of the air driving unit 11, efficient dust collection and cleaning are realized. Moreover, the dust collecting box 3 is arranged adjacent to the fluid storage device 2, which helps to optimize the internal space layout of the cleaning device, so that the overall structure is more compact and reasonable. During the operation of the cleaning device, the compact layout can also reduce the length of the connecting pipeline between the components, reduce the air resistance and energy loss.

[0067] In the above embodiment, referring to FIGS. 1 and 2, the cross-sectional area of the dust suction port 31 is greater than that of the air outlet 32.

[0068] The larger passage area of the dust suction port 31 than the passage area of the air outlet 32 can be understood as that the cross-sectional area of the dust suction port 31 in the airflow passing direction is larger than the cross-sectional area of the air outlet 32 in the airflow passing direction. That is, the space for the airflow to pass through the dust suction port 31 is larger than the space for the airflow to pass through the air outlet 32.

[0069] It should be noted that the larger dust suction port 31 can allow more dust-containing airflow to enter the cleaning device. This allows the cleaning device to suck up more dust and debris in the same time, improving the dust collection efficiency. For example, when cleaning a larger area of the ground or a more dirty environment, the dust and other pollutants can be quickly sucked in, reducing the cleaning time. At the same time, due to the large area of the dust suction port 31, the airflow entering the cleaning device is relatively gentle. This can reduce the possibility of dust flying and secondary pollution caused by high-speed airflow. At the same time, the small area of the air outlet 32 allows the airflow to maintain a certain pressure inside the cleaning device, ensuring that the airflow can be smoothly discharged and maintaining stable airflow in the system. At the same time, the combination of the larger dust suction port 31 and the smaller air outlet 32 helps to reduce the noise generated by the airflow flowing inside the cleaning device. The airflow speed at the dust suction port 31 is relatively low, reducing the noise source generated by high-speed airflow. While the airflow speed at the air outlet 32 increases due to the small area, the overall noise level can still be controlled to a certain extent.

[0070] In some possible implementation embodiments provided in the present application, referring to FIG. 2, the surrounding wall of the air duct 12 includes a first guide plate 121, which is arranged on the side of the air duct 12 close to the fluid storage device 2. The first guide plate 121 is in a straight line type and is inclined upward from the direction away from the dust collection box 3 to the direction close to the dust collection box 3.

[0071] The first guide plate 121 can be a side wall surface of the boundary of the air duct 12, specifically, a side wall surface of the container wall of the fluid storage device 2 in the air duct 12. That is, the first guide plate 121 is a wall surface of the surrounding wall of the air duct 12 close to the fluid storage device 2.

[0072] The shape of the first guide plate 121 can be a straight line without bending or other complex shapes.

[0073] Specifically, from a position far away from the dust collection box 3 to a position close to the dust collection box 3, the first guide plate 121 is in an upwardly inclined state. That is, the low end of the first guide plate 121 is in the direction away from the dust collection box 3, and the high end is in the direction close to the dust collection box 3, and the whole forms an upwardly inclined shape.

[0074] It should be noted that the upwardly inclined design of the first flow guide plate 121 can guide the airflow more smoothly from the end close to the dust collection box 3 to the end away from the dust collection box 3, reduce the resistance and turbulence of the airflow, and improve the flow efficiency of the airflow in the air duct 12. At the same time, the inclined first flow guide plate 121 can reduce the direct impact of the airflow on the surrounding wall of the air duct 12 and the fluid storage device 2, reduce the risk of component damage, and prolong the service life.

[0075] In some possible implementation embodiments provided in the present application, referring to FIG. 2, when the wind-driven unit 11 is arranged in an inclined manner, the inclination angle of the wind-driven unit 11 is greater than the inclination angle of the first flow guide plate 121.

[0076] The inclination angle of the wind-driven unit 11 can be regarded as the inclination angle of the axis of the wind-driven unit 11 relative to the traveling direction of the cleaning device. The inclination angle of the first flow guide plate 121 can be regarded as the inclination angle of the first flow guide plate 121 relative to the traveling direction of the cleaning device.

[0077] Specifically, since the overall posture of the wind-driven unit 11 is inclined backward relative to the traveling direction of the cleaning device, and the inclination angle of the wind-driven unit 11 is greater than the inclination angle of the first flow guide plate 121, that is, the first flow guide plate 121 is inclined forward relative to the wind-driven unit 11.

[0078] It should be noted that the first flow guide plate 121 is inclined forward relative to the wind-driven unit 11. From the perspective of airflow guidance, the forwardly inclined first flow guide plate 121 can guide the incoming airflow in advance when the cleaning device is working. This makes the airflow flow more smoothly to the air inlet of the wind-driven unit 11, reduces the turbulence and resistance of the airflow. In this way, the wind-driven unit 11 does not need to spend too much energy to overcome the resistance caused by irregular airflow when inhaling air, thereby reducing the working load of the wind-driven unit 11, reducing the energy consumption of the cleaning device, and prolonging the battery endurance time. At the same time, it can make the center of gravity of the cleaning device more reasonable during operation, reduce the shaking and instability factors, and improve the stability of operation. At the same time, a more compact layout can be achieved in the limited internal space of the device main body, leaving more space for other components.

[0079] In the above embodiment, the minimum spacing distance between the wind-driven unit 11 and the first flow guide plate 121 is 3 mm.

[0080] The minimum spacing distance of 3 mm can be understood as that the distance between the wind-driven unit 11 and the first flow guide plate 121 will not be less than 3 mm, regardless of any operating state or position of the cleaning device.

[0081] It should be noted that the minimum spacing distance of 3mm can to some extent avoid the airflow generated when the wind-driven unit 11 is running from directly interfering with the first guide plate 121, making the airflow flow more smoothly and improving the efficiency of the air duct 12. At the same time, it can reduce the friction and collision noise caused by the airflow being too close to the first guide plate 121, thereby reducing the overall operating noise of the cleaning equipment. At the same time, it can ensure that the wind-driven unit 11 and the first guide plate 121 do not easily collide with each other during the operation of the cleaning equipment, even when vibrating or affected by external forces, reducing the risk of component damage. At the same time, the 3mm spacing helps air flow between them, providing some heat dissipation space for the wind-driven unit 11. Because the wind-driven unit 11 generates heat when working, moderate air flow can carry away some heat to avoid overheating, thereby maintaining good working performance and prolonging service life. At the same time, the 3mm spacing distance reduces the resistance of the airflow to some extent. If the spacing is too small, the airflow will be excessively compressed, increasing wind resistance, leading to increased energy consumption and reduced suction. The 3mm spacing allows the airflow to pass relatively smoothly, reducing energy loss and improving the energy utilization efficiency of the cleaning equipment.

[0082] In some possible implementation embodiments provided in the present application, referring to FIGS. 1 and 2, the surrounding wall of the air duct 12 further includes a second guide plate 122, which is arranged on the side of the air duct 12 away from the fluid storage device 2. The second guide plate 122 includes a bent portion 1221, which is arranged close to the air outlet 32 and transitions in an arc shape.

[0083] Specifically, the second guide plate 122 can be the wall surface of the boundary of the air duct 12 on the side opposite to the first guide plate 121, that is, the wall surface on the side away from the fluid storage device 2.

[0084] Specifically, the second guide plate 122 includes a straight portion and a bent portion 1221. The straight portion is linear, and the bent portion 1221 is arc-shaped. The straight portion and the bent portion 1221 are continuously and smoothly transitioned.

[0085] Specifically, the bent portion 1221 is arranged close to the air outlet 32 of the dust collection box 3 and is bent toward the upward direction.

[0086] It should be noted that the bent portion 1221, which transitions in an arc shape and is bent upward, can more smoothly guide the airflow to flow out of the air outlet 32, reduce the resistance and turbulence of the airflow, and improve the airflow transmission efficiency. At the same time, it helps to reduce the pressure loss of the airflow at the bending portion, so that the energy of the wind-driven unit 11 can be more effectively converted into dust collection power. At the same time, it can reduce the noise generated by the airflow impact and turbulence, making the cleaning equipment run more quietly. At the same time, it can also reduce the impact of the airflow on the surrounding wall of the air duct 12, reduce the risk of component wear and damage, and prolong the service life.

[0088] In the filter component 5, the filter component 5 can be a multi-layer fine-woven polyester fiber filter screen, a high-density sponge, or a metal screen with static electricity, etc.

[0089] Specifically, the filter component 5 is detachably arranged in the dust collecting box 3. As an implementation, a buckle structure is arranged on the dust collecting box 3 and the filter component 5 respectively, and the buckle structure is buckled or released by pressing or twisting, so as to realize the installation and dismounting of the filter component 5. As another implementation, a sliding rail and a sliding block are arranged on the dust collecting box 3 and the filter component 5 respectively, and the filter component 5 is connected or separated from the dust collecting box 3 by inserting the sliding block into the sliding rail and sliding. As another implementation, a thread is arranged on the dust collecting box 3 and the filter component 5 respectively, and the filter component 5 is installed or dismounted by rotating the filter component 5 to cooperate with the thread on the dust collecting box 3. As another implementation, a magnetic material is arranged on the dust collecting box 3 and the filter component 5 respectively, and the filter component 5 is connected with the dust collecting box 3 by magnetic force.

[0090] It should be noted that the filter component 5 arranged in the dust collecting box 3 can effectively block dust from entering the air duct 12, prevent dust from accumulating in the air duct 12, and thus maintain the smoothness and cleanliness of the air duct 12, which helps to maintain good airflow and dust collection effect. At the same time, it can reduce the dust entering the air drive unit 11, reduce the risk of wear and failure of the air drive unit 11, and prolong the service life of the air drive unit 11. At the same time, it can avoid the dust in the air duct 12 from being blown out again under the action of airflow, causing secondary pollution of the indoor environment.

[0091] In the cleaning device provided in the embodiments of the present application, the airflow driving assembly 1 and the fluid storage device 2 are in a superposed form. Compared with the traditional front-rear or left-right arrangement, the horizontal and vertical space is saved, the internal structure of the device body is simplified, the utilization rate of the internal space of the device body is improved, and thus the overall volume of the cleaning device is reduced, so that the cleaning device can work freely and be stored conveniently in a narrow space. At the same time, this is also beneficial to optimizing the gravity distribution of the cleaning device. When the airflow driving assembly 1 is located at the upper side and the fluid storage device 2 is located at the lower side, the cleaning device can be more stable during operation, especially when moving quickly, turning or crossing some small obstacles, and the possibility of tilting is significantly reduced.
