[0002] With the continuous advancement of science and technology and the gradual improvement of people's living standards, cleaning equipment, such as sweeping and mopping robots, are gradually becoming part of our daily lives.

[0003] A sweeping and mopping robot incorporates a water tank and fan, with the fan positioned at the rear (near the tail) and the water tank at the front (near the head). This allows the robot to sweep and mop forward while the fan collects dust and the water tank at the front wets the mop. Alternatively, the water tank can be located at the rear of the robot, with the fan near the head, discharging water to the mop before moving forward to clean. However, this lack of compactness in the positioning of the water tank and fan results in wasted internal space, making the robot larger and less suitable for operation and storage in confined spaces.

[0029] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0030] An embodiment of the first aspect of the present invention provides a cleaning device, wherein the cleaning system cleaning device can be a sweeping robot, a mopping robot, an all-in-one sweeping and mopping machine, or other cleaning devices that meet the requirements.

[0031] Specifically, the cleaning equipment includes but is not limited to: an equipment body, a sensing system, a control system, a drive system, a cleaning system, an energy system, and a human-computer interaction system. The above-mentioned systems coordinate with each other to enable the cleaning equipment to move autonomously to achieve the cleaning function. The functional components and the like that constitute the above-mentioned systems in the cleaning equipment are integrated into the equipment body. It is understandable that the cleaning equipment can be a self-moving cleaning equipment, wherein the self-moving cleaning equipment is a device that automatically performs cleaning operations in a certain area to be cleaned without user operation.

[0032] The embodiment of the second aspect of the present invention provides a cleaning system, wherein the cleaning system includes a base station, and the base station is used in conjunction with a cleaning device.

[0033] Specifically, when the cleaning device starts working, the cleaning device starts from the base station to perform the cleaning task. When the base station performs charging or other operations, such as water replenishment, and / or cleaning, and / or dust collection, the cleaning device starts from the base station to perform the cleaning task.

[0034] See also Figure 1 and Figure 2 As shown, in an embodiment of the first aspect of the present invention, the cleaning device includes an airflow drive component 1 and a fluid storage device 2, the airflow drive component 1 and the fluid storage device 2 are stacked up and down, and the fluid storage device 2 is arranged on the side of the airflow drive component 1 close to the surface to be cleaned.

[0035] It should be noted that the airflow drive component 1 and the fluid storage device 2 are arranged in an upper and lower stacking manner, which greatly saves horizontal and vertical space compared to the traditional front-to-back or left-to-right layout, simplifies the internal structure of the cleaning equipment, improves the utilization rate of the internal space of the cleaning equipment, and reduces the overall volume of the cleaning equipment, so that it can operate flexibly and be conveniently stored in a narrow space.

[0036] The cleaning device may be a sweeping robot, a mopping robot, an all-in-one sweeper and mop machine, or other devices that meet the requirements and automatically perform cleaning operations in a certain area to be cleaned without user operation.

[0037] Specifically, the cleaning equipment includes but is not limited to a sensing system, a drive system, a cleaning system, an energy system, a human-computer interaction system, etc. The functional components of each of the above systems are integrated into the main body of the equipment and work in coordination with each other, enabling the cleaning equipment to move autonomously to perform its cleaning function.

[0038] Among them, in this embodiment, the cleaning device is a sweeping and mopping machine, and its cleaning system includes a cleaning component and a mopping component. The cleaning component includes a side brush located on one side of the sweeping and mopping machine, which is used to sweep dust, debris, etc. from corners and walls to the bottom of the machine; a main brush 4 located at the bottom of the sweeping and mopping machine, which is responsible for collecting garbage and drawing it into the dust suction channel; and a dust suction fan, which generates suction and sucks dust and small particles of garbage on the ground into the dust collection box 3. The mopping component includes a mop, which directly contacts the surface to be cleaned and wipes stains and water stains; a water tank, which provides the water needed to moisten the mop; and a pressure device, which applies a certain amount of pressure to the mop to enhance the mopping effect. It can be understood that the surface to be cleaned can be the ground or carpet, etc. When the sweeping and mopping machine moves on the surface to be cleaned, the cleaning component can achieve dry cleaning, and the mopping component can achieve wet cleaning.

[0039] It should be noted that, in this embodiment, the airflow drive assembly 1 is a part of the cleaning assembly, and the airflow drive assembly 1 includes a wind drive unit 11, which is specifically a fan, used to generate suction gas passing through the dust box 3 to suck the garbage swept up by the main brush 4 into the dust box 3; the fluid storage device 2 is a part of the mopping assembly, and the fluid storage device 2 is specifically a water tank, which is used to distribute cleaning fluid on at least a part of the width of the mop and the surface to be cleaned, so as to soak at least a part of the mop.

[0040] The airflow driving assembly 1 and the fluid storage device 2 are arranged inside the main body of the cleaning device and are distributed up and down.

[0041] Specifically, in this embodiment, the airflow drive assembly 1 is located at the upper part of the equipment body, and the fluid storage device 2 is located at the lower part of the equipment body. In other words, the airflow drive assembly 1 and the fluid storage device 2 are stacked up and down, wherein the airflow drive assembly 1 is at the top and the fluid storage device 2 is at the bottom. It should be noted that the airflow drive assembly 1 and the fluid storage device 2 are stacked up and down, which greatly saves horizontal and vertical space compared to the traditional front-to-back or left-to-right layout, simplifies the internal structure of the equipment body, improves the utilization rate of the internal space of the equipment body, reduces the overall volume of the cleaning equipment, and enables it to operate flexibly and be stored conveniently in a narrow space; at the same time, it is also conducive to optimizing the center of gravity distribution of the cleaning equipment. When the airflow drive assembly 1 is on top and the fluid storage device 2 is on the bottom, the cleaning equipment can be made more stable during operation, especially when moving quickly, turning or crossing some small obstacles, reducing the risk of tipping over.

[0042] In the above embodiment, see Figure 1 and Figure 2 As shown, the airflow drive assembly 1 includes a wind drive unit 11 and an air duct 12. The air duct 12 is connected to the air inlet end of the wind drive unit 11, and at least part of the surrounding wall of the air duct 12 close to the side of the fluid storage device 2 constitutes part of the container wall of the fluid storage device 2.

[0043] Among them, the air duct 12 is located inside the main body of the device, and is used to connect the wind drive unit 11 and the dust collection box 3 and other components to guide the airflow and ensure that the suction force generated by the wind drive unit 11 can be effectively transmitted to the dust collection box 3 and other dust collection accessories, thereby sucking in dust, debris, etc. on the surface to be cleaned.

[0044] The airflow driving component 1 and the fluid storage device 2 are arranged in a stacked manner, specifically, the air duct 12 and the fluid storage device 2 are stacked in a stacked manner.

[0045] Specifically, in this embodiment, the fluid storage device 2 is positioned between the air duct 12 and the bottom surface of the device body. At least a portion of the wall of the air duct 12 on the side closest to the fluid storage device 2 serves as a portion of the top wall of the fluid storage device 2. This effectively conserves internal space within the device body, making the overall structure more compact and helping to reduce the size of the cleaning device. This combination also enhances the integration of the cleaning device's internal structure, reduces the number of independent components, and reduces assembly complexity and cost.

[0046] 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, since the fluid storage device 2 occupies a certain space, the airflow channel in the air duct 12 is relatively clear and regular. The airflow flows in a relatively confined and regular space, and it is not easy for chaotic airflow to converge and vortex to form. The suction fluctuation caused by the vortex is reduced, so that the suction remains relatively stable during the operation, ensuring the quality consistency of the cleaning work. At the same time, the airflow flows smoothly, the wind resistance is reduced, and the wind drive unit 11 does not need to consume too much energy to overcome the resistance, thereby reducing the overall energy consumption of the cleaning equipment and extending the battery life. At the same time, the stable and regular airflow can reduce the noise generated by airflow turbulence and vortex formation, making the cleaning equipment quieter during operation. At the same time, it avoids the excessive local pressure or airflow impact caused by vortexes, reduces the wear and damage to the air duct 12 and related components, and extends the service life of the cleaning equipment.

[0047] In some possible embodiments provided by the present invention, the wind-driven unit 11 is arranged at an angle.

[0048] The tilted arrangement of the wind drive unit 11 can be understood as the installation position of the wind drive unit 11 is not completely horizontal or vertical, but forms a certain angle with the horizontal or vertical reference plane of the cleaning equipment.

[0049] Specifically, the axis of the wind-driven unit 11 may have a certain inclination angle relative to the chassis plane or the forward direction of the cleaning device. This inclination may be forward, backward, left or right. In this embodiment, the overall posture of the wind-driven unit 11 is tilted backward relative to the forward direction of the cleaning device.

[0050] It should be noted that the overall posture of the wind drive unit 11 is tilted backward relative to the forward direction of the cleaning equipment, which can better arrange the layout of the wind drive unit 11 and other components in the limited internal space of the equipment body, improve space utilization, and make the structure of the cleaning equipment more compact.

[0051] In some possible implementations of the present invention, see Figure 2 As shown, the air duct 12 is straight or has no more than one smoothly transitioned bending structure.

[0052] The air duct 12 being linear can be understood as the air duct 12 being straight from one end to the other without any bends or turns.

[0053] The fact that the air duct 12 has no more than one smoothly transitioned bend structure can be understood as meaning that the air duct 12 may have a bend, but such bend may only have one, and such bend is not a sudden, sharp corner, but rather a carefully designed smooth transition. For example, the air duct 12 may have a slow, smooth arc bend at a certain location to accommodate the spatial layout or functional requirements within the device body.

[0054] It should be noted that the straight-line or smoothly curved air duct 12 can minimize the resistance encountered by the airflow as it flows through the air duct 12, allowing the suction force generated by the wind-driven unit 11 to be more effectively transferred to the dust collection box 3, thereby improving the dust collection efficiency. It also helps maintain the stability of the airflow, reduces airflow turbulence and vortices, and makes the suction force more uniform and continuous. Reduced wind resistance and stable airflow can also reduce the noise generated by turbulent airflow, making the cleaning device quieter during operation. Reducing wind resistance can also reduce the energy consumption of the wind-driven unit 11, extending the working time of the cleaning device or completing more cleaning tasks with the same amount of power. The relatively simple shape of the air duct 12 is less likely to accumulate dust and debris, making it easier to clean and maintain later and keeping the air duct 12 unobstructed. This relatively simple air duct 12 structure also helps to rationally arrange the device within the limited internal space of the device body, leaving more installation space for other components.

[0055] In some possible implementations provided by the present invention, participating Figure 2 As shown, the air duct 12 has a passage area that gradually decreases along the flow direction.

[0056] Air duct 12 is the passage through which air flows within the device. The flow direction refers to the direction of the airflow in air duct 12. The gradually decreasing flow area along the flow direction means that, starting from the air inlet of air duct 12, the cross-sectional area of air duct 12 in the direction of airflow gradually decreases as the airflow advances along air duct 12.

[0057] Specifically, the air inlet of the air duct 12 is connected to the dust box 3, and the air outlet of the air duct 12 is connected to the wind drive unit 11. When the wind drive unit 11 is in operation, the suction force generated is transmitted to the dust box 3 through the air duct 12. In other words, the cross-sectional area of the air duct 12 gradually decreases as the dust box 3 moves toward the wind drive unit 11.

[0058] It should be noted that as the passage area of the air duct 12 gradually decreases, the air flow velocity will increase accordingly according to the continuity principle. Higher wind speeds help improve dust collection capabilities and more effectively draw dust and debris into the dust box 3. At the same time, the accelerated air flow velocity can generate stronger suction, which is more effective for adsorbing heavier or tightly adhered dirt. At the same time, stronger suction can collect dust and debris more quickly and thoroughly, reducing omissions during the cleaning process. At the same time, it helps to compress the inhaled air flow, collect more dust and debris in the same volume, and improve the accommodation efficiency of the dust box 3. At the same time, the flow state of the air flow can be adjusted to make it more stable, reduce the generation of turbulence and vortices, and thus reduce noise and energy loss. At the same time, the passage area of the air duct 12 gradually decreases along the flow direction, which can better adapt to the complex spatial layout inside the device body and achieve better air duct 12 performance in a limited space.

[0059] In some possible implementations of the present invention, see Figure 1 and Figure 2 As shown, the cleaning device also includes a dust box 3 and a main brush 4. The main brush 4 is carried at the bottom of the cleaning device. The dust box 3 is placed adjacent to the fluid storage device 2. The dust box 3 includes a dust suction port 31 and an air outlet 32. The dust suction port 31 is set toward the main brush 4, and the air outlet 32 is connected to the air duct 12.

[0060] The main brush 4 may be a roller brush, which is rotatably arranged at the bottom of the self-moving device and is used for directly contacting the surface to be cleaned to perform cleaning work.

[0061] Specifically, the dust collection port 31 of the dust collection box 3 is arranged toward the main brush 4. When the main brush 4 rotates and cleans, it can sweep dust and debris directly toward the dust collection port 31, so that the dust and debris are quickly sucked into the dust collection box 3. The connection between the air outlet 32 of the dust collection box 3 and the air duct 12 ensures that the airflow can smoothly enter the air duct 12, and then under the action of the wind drive unit 11, efficient dust collection and cleaning are achieved. In addition, the dust collection box 3 is arranged adjacent to the fluid storage device 2, which helps to optimize the internal space layout of the cleaning equipment and make the overall structure more compact and reasonable. During the operation of the cleaning equipment, this tight layout can also reduce the length of the connecting pipes between components, reducing wind resistance and energy loss.

[0062] In the above embodiment, see Figure 1 and Figure 2 As shown, the passage area of the dust suction port 31 is larger than the passage area of the air outlet 32 .

[0063] The fact that the passage area of the dust suction port 31 is larger than that of the air outlet 32 can be understood as the cross-sectional area of the dust suction port 31 in the direction of air flow passing through is larger than the cross-sectional area of the air outlet 32 in the direction of air flow passing through. In other words, the dust suction port 31 has a larger space for air flow passing through than the air outlet 32.

[0064] It should be noted that the larger suction port 31 allows more dust-laden air to enter the cleaning device. This allows the cleaning device to absorb more dust and debris in the same amount of time, improving suction efficiency. For example, when cleaning a large floor area or a relatively dirty environment, dust and other contaminants can be sucked in more quickly, reducing cleaning time. Furthermore, due to the large area of the suction port 31, the airflow velocity entering the cleaning device is relatively gentle. This reduces the possibility of dust flying and secondary contamination caused by excessive airflow. Furthermore, the smaller area of the air outlet 32 allows the airflow to maintain a certain pressure within the cleaning device, ensuring smooth discharge and maintaining stable airflow within the system. Furthermore, the combination of the larger suction port 31 and the smaller air outlet 32 helps reduce the noise generated by the airflow within the cleaning device. The relatively low airflow velocity at the suction port 31 reduces the noise source caused by high-speed airflow. While the airflow velocity at the smaller area of the air outlet 32 increases, the overall noise level can still be controlled to a certain extent.

[0065] In some possible implementations of the present invention, see Figure 2 As shown, 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 straight and tilted upward in the direction away from the dust box 3 to close to the dust box 3.

[0066] The first deflector 121 may be a wall surface at the boundary of the air duct 12, specifically, the wall surface of the air duct 12 that constitutes the container wall of the fluid storage device 2. In other words, the first deflector 121 is the wall surface of the air duct 12 that is close to the fluid storage device 2.

[0067] The shape of the first guide plate 121 can be a straight line without any bends or other complex shapes.

[0068] Specifically, when viewed from a position farther from the dust box 3 to a position closer to the dust box 3, the first guide plate 121 is tilted upward. In other words, the lower end of the first guide plate 121 is in a direction away from the dust box 3, and the upper end is in a direction closer to the dust box 3, forming an overall upward tilt.

[0069] It should be noted that the upwardly inclined design of the first guide plate 121 can guide the airflow more smoothly from the end closer to the dust box 3 to the end farther away from the dust box 3, reducing airflow resistance and turbulence, and improving the flow efficiency of the airflow in the air duct 12. At the same time, the inclined first guide plate 121 can reduce the direct impact of the airflow on the walls of the air duct 12 and the fluid storage device 2, reducing the risk of component damage and extending the service life.

[0070] In some possible implementations of the present invention, see Figure 2 As shown, when the wind-driven unit 11 is tilted, the tilt angle of the wind-driven unit 11 is greater than the tilt angle of the first guide plate 121 .

[0071] The tilt angle of the wind drive unit 11 can be regarded as the tilt angle of the axis of the wind drive unit 11 relative to the direction of travel of the cleaning device. The tilt angle of the first guide plate 121 can be regarded as the tilt angle of the first guide plate 121 relative to the direction of travel of the cleaning device.

[0072] Specifically, since the overall posture of the wind-driven unit 11 is tilted backward relative to the traveling direction of the cleaning equipment, and the inclination angle of the wind-driven unit 11 is greater than the inclination angle of the first guide plate 121, that is, the first guide plate 121 is tilted forward compared to the wind-driven unit 11.

[0073] It should be noted that the first guide plate 121 is tilted forward compared to the wind-driven unit 11. From the perspective of airflow guidance, the forward-tilted first guide plate 121 can guide the incoming airflow in advance when the cleaning device is working. This allows the airflow to flow more smoothly to the air inlet of the wind-driven unit 11, reducing the turbulence and resistance of the airflow. In this way, the wind-driven unit 11 does not need to expend too much energy to overcome the obstruction caused by irregular airflow when inhaling air, thereby reducing the workload of the wind-driven unit 11, reducing the energy consumption of the cleaning device, and extending the battery life. At the same time, it can make the center of gravity distribution of the cleaning device more reasonable during operation, reduce 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 body, leaving more space for other components.

[0074] In the above embodiment, the minimum spacing distance between the wind driving unit 11 and the first guide plate 121 is 3 mm.

[0075] The minimum spacing distance of 3 mm can be understood as that between the wind drive unit 11 and the first guide plate 121, the distance therebetween will not be less than 3 mm regardless of any operating state or position of the cleaning device.

[0076] It should be noted that the minimum spacing of 3mm can, to a certain extent, prevent direct interference between the airflow generated by the wind-driven unit 11 and the first deflector 121 during operation, ensuring smoother airflow and improving the efficiency of the air duct 12. It can also reduce friction and collision noise caused by the airflow coming too close to the first deflector 121, thereby reducing the overall operating noise of the cleaning device. Furthermore, it ensures that the wind-driven unit 11 and the first deflector 121 are less likely to collide with each other during operation, even when subjected to vibration or external forces, reducing the risk of component damage. Furthermore, the 3mm spacing facilitates air circulation between them, providing sufficient space for the wind-driven unit 11 to dissipate heat. Because the wind-driven unit 11 generates heat during operation, adequate airflow can dissipate some of this heat, preventing overheating, thereby maintaining good operating performance and extending its service life. Furthermore, the 3mm spacing reduces resistance to airflow. If the spacing is too small, the airflow will be excessively squeezed, increasing wind resistance, resulting in increased energy consumption and reduced suction. A 3mm spacing, on the other hand, allows for smoother airflow, reducing energy loss and improving the energy efficiency of the cleaning device.

[0077] In some possible implementations of the present invention, see Figure 1 and Figure 2 As shown, the surrounding wall of the air duct 12 also 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 bending portion 1221, which is arranged close to the air outlet 32 and has an arc-shaped transition.

[0078] The second guide plate 122 may be a wall surface at the boundary of the air duct 12 on the side opposite to the first guide plate 121 , specifically a wall surface on the side away from the fluid storage device 2 .

[0079] 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 have a continuous and smooth transition.

[0080] Specifically, the bent portion 1221 is disposed close to the air outlet 32 of the dust box 3 and is bent upward.

[0081] It should be noted that the curved, upwardly curved bend 1221 can more smoothly guide the airflow out of the air outlet 32, reducing airflow resistance and turbulence, and improving airflow transmission efficiency. It also helps reduce pressure loss at the bend, allowing the energy of the wind-driven unit 11 to be more efficiently converted into dust collection power. It can also reduce noise caused by airflow impact and turbulence, making the cleaning device run quieter. It can also reduce the impact of airflow on the walls of the air duct 12, reducing the risk of wear and damage to components and extending their service life.

[0082] In some possible implementations of the present invention, see Figure 1 and Figure 2 As shown, a filter component 5 is detachably provided in the dust box 3 , and the filter component 5 is used to prevent dust from entering the air duct 12 .

[0083] The filter component 5 can be a multi-layer finely woven polyester fiber filter, a high-density sponge, or a metal mesh with static electricity.

[0084] Specifically, the filter component 5 is detachably arranged in the dust box 3. As one embodiment, mutually cooperating snap-fit structures are respectively provided on the dust box 3 and the filter component 5. By pressing or twisting, the snap-fits are engaged or released with each other, thereby achieving installation and removal of the filter component 5. As another embodiment, slide rails and sliders are respectively provided on the dust box 3 and the filter component 5. By inserting the sliders into the slide rails and sliding them, the filter component 5 is connected to or separated from the dust box 3. As another embodiment, threads are respectively provided on the dust box 3 and the filter component 5. By rotating the filter component 5, the threads are engaged with the threads on the dust box 3, thereby achieving installation and removal. As yet another embodiment, magnetic materials are respectively provided on the dust box 3 and the filter component 5. The filter component 5 is connected to the dust box 3 by magnetic adsorption.

[0085] It should be noted that the filter component 5 provided in the dust box 3 can effectively block dust from entering the air duct 12, preventing dust accumulation within the air duct 12, thereby keeping the air duct 12 unobstructed and clean, and helping to maintain good airflow and dust collection. It can also reduce the amount of dust entering the wind drive unit 11, reducing the risk of wear and failure, and extending the service life of the wind drive unit 11. It also prevents dust in the air duct 12 from being blown out again by the airflow, causing secondary pollution to the indoor environment.

[0086] In the cleaning equipment provided in the embodiment of the present invention, the airflow drive component 1 and the fluid storage device 2 are stacked up and down. Compared with the traditional front-to-back or left-to-right arrangement, this saves horizontal and vertical space, simplifies the internal structure of the equipment body, improves the utilization rate of the internal space of the equipment body, and thus reduces the overall volume of the cleaning equipment, allowing it to operate freely and be conveniently stored in a narrow space. At the same time, this is also beneficial to optimizing the center of gravity distribution of the cleaning equipment. When the airflow drive component 1 is at the top and the fluid storage device 2 is at the bottom, the cleaning equipment can be more stable during operation, especially when moving quickly, turning, or crossing some small obstacles, which significantly reduces the possibility of tipping over.

[0087] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0088] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention. The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art may make various improvements and variations without departing from the technical principles of the present invention, and such improvements and variations shall also be considered within the scope of protection of the present invention.
