Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning robots, and in particular to a cleaning device and a cleaning system. BACKGROUND

[0002] With the development of science and technology, various cleaning devices are widely used in people's daily life, such as a sweeping and mopping integrated cleaning robot.

[0003] In the related art, the sweeping and mopping integrated cleaning robot includes a housing and components such as a water tank and a cleaning assembly arranged in the housing. The water tank and the cleaning assembly are arranged on the bottom wall of the housing. The cleaning assembly includes various functional components that play their respective cleaning functions to clean the surface to be cleaned. With the increase of the functions of the sweeping and mopping integrated cleaning robot, the number of functional components also increases. In order to ensure the miniaturization of the volume of the sweeping and mopping integrated cleaning robot, it is particularly important to improve the utilization rate of the space in the housing. CONTENT OF THE UTILITY MODEL

[0004] To solve the above technical problems, the present application provides a cleaning device and a cleaning system for improving the utilization rate of the space in the housing of the cleaning device to ensure the miniaturization of the volume of the cleaning device.

[0005] The present application is implemented by the following technical solutions.

[0006] The first aspect of the present application provides a cleaning device, which includes a housing, a cleaning assembly and a liquid storage tank. The housing forms an accommodation space inside. The cleaning assembly is arranged in the accommodation space. The cleaning assembly at least includes a mop driving module for connecting and controlling the movement of the mop outside the accommodation space to clean the surface to be cleaned. The liquid storage tank is arranged in the accommodation space, and at least part of the liquid storage tank is located below the cleaning assembly.

[0007] In the technical solution of the present application, the housing provides an accommodation space for the cleaning assembly and the liquid storage tank. The cleaning assembly can clean the surface to be cleaned, and at least one cleaning method is to drive the mop to move by using the mop driving module to clean the surface to be cleaned.

[0008] Since at least part of the liquid storage tank is located below the cleaning assembly, the cleaning assembly and the liquid storage tank are arranged in a top-down stacked manner, which can save space in the horizontal direction of the containing space, provide more space in the horizontal direction for placing other functional components, thereby improving the utilization rate of the containing space, ensuring the miniaturization of the shell, so that the cleaning device can work in a narrow space. In addition, since the liquid storage tank is at least partially located below the cleaning assembly, the cleaning liquid is contained in the liquid storage tank, and when the cleaning device moves, the center of gravity of the entire cleaning device is lower, which can improve the stability of the cleaning device during movement, especially when passing through some curves or crossing some obstacles. The advantages of arranging the liquid storage tank below the cleaning assembly are more obvious.

[0009] In some embodiments of the present application, the cleaning assembly further comprises a dust removal module; the liquid storage tank comprises a first tank body part and a second tank body part in communication with each other, and the first tank body part and the second tank body part are arranged on the bottom wall of the containing space; at least part of the first tank body part is located below the mop driving module, and the second tank body part is located below the dust removal module.

[0010] In this way, the space below the mop driving module and the dust removal module is utilized, further improving the space utilization.

[0011] In some embodiments of the present application, the number of mop driving modules is at least two, and the at least two mop driving modules comprise a non-swinging mop driving module and a swingable mop driving module; at least part of the first tank body part is located below the non-swinging mop driving module.

[0012] Since the structure of the non-swinging mop driving module is relatively simple compared to the structure of the swingable mop driving module, the first tank body part can be conveniently arranged.

[0013] In some embodiments of the present application, in the direction approaching the second tank body part, the first tank body part comprises a distal sub-tank body, a bearing sub-tank body and a connecting sub-tank body in sequence, and the connecting sub-tank body communicates with the second tank body part. The bearing sub-tank body is arranged below the non-swinging mop driving module.

[0014] In this way, under the condition that the position of the non-swinging mop driving module is fixed, the non-swinging mop driving module has a connecting sub-tank body on the side close to the second tank body part and a distal sub-tank body on the side away from the second tank body part, thereby fully utilizing the space on both sides of the non-swinging mop driving module in the direction approaching the second tank body part.

[0015] In some embodiments of the present application, the non-swing mop driving module comprises a motor and a transmission part, the transmission part is in transmission connection with the mop. The bearing sub-box comprises a motor sub-box and a transmission sub-box which are in communication with each other, the motor sub-box and the transmission sub-box are laid on the bottom wall of the accommodating space, the motor sub-box is below the motor, and the transmission sub-box is below the transmission part.

[0016] In this way, the motor and the transmission part are laid flat, so that the height of the non-swing mop driving module and the height of the control shell can be controlled, and the space utilization can be improved by arranging the motor sub-box below the motor and the transmission sub-box below the transmission part.

[0017] In some embodiments of the present application, the motor sub-box is in a disc structure, and the upper surface of the disc structure is in contact with the lower end surface of the motor.

[0018] In this way, the motor sub-box can be used to dissipate heat of the motor.

[0019] In some embodiments of the present application, the upper end of the distal sub-box is lower than or flush with the upper end of the non-swing mop driving module.

[0020] In this way, when the upper end of the non-swing mop driving module is in contact with the upper wall of the accommodating space, the distal sub-box can avoid interfering with the upper wall of the accommodating space.

[0021] In some embodiments of the present application, the liquid storage tank has at least one liquid outlet channel and a liquid inlet channel, at least one of the at least one liquid outlet channel and the liquid inlet channel is arranged on the distal sub-box and / or the connecting sub-box.

[0022] Since the cleaning assembly is not arranged above the distal sub-box and the connecting sub-box, the liquid outlet channel and the liquid inlet channel can be arranged conveniently.

[0023] In some embodiments of the present application, the at least one liquid outlet channel comprises an overflow channel arranged at the upper end of the liquid storage tank. The cleaning device further comprises a first pump body connected to the liquid inlet channel, the first pump body is used to pump the cleaning liquid into the liquid storage tank, and the cleaning liquid can overflow from the overflow channel to the mop connected to the mop driving module.

[0024] In this way, after the liquid storage tank is filled with enough cleaning liquid by using the first pump body, the excess cleaning liquid can overflow from the overflow channel to the mop connected to the mop driving module to clean the mop connected to the mop driving module, and one power source is used to fill the liquid storage tank and clean the mop connected to the mop driving module.

[0025] In some embodiments of the present application, the swingable mop driving module is arranged on the side of the dust removal module away from the non-swingable mop driving module. The number of overflow channels is at least two, and the at least two overflow channels include a first overflow channel and a second overflow channel. The first overflow channel is arranged on the distal sub-tank body, and the cleaning liquid in the liquid storage tank can overflow to the mop connected to the non-swingable mop driving module through the first overflow channel. The second overflow channel is arranged on the connecting sub-tank body, and the cleaning liquid in the liquid storage tank can overflow to the mop connected to the swingable mop driving module through the second overflow channel.

[0026] Through the above arrangement, the connecting sub-tank body is closer to the mop connected to the swingable mop driving module, so that the first overflow channel is arranged on the connecting sub-tank body, which can facilitate the flow of cleaning liquid in the first overflow channel to the mop connected to the swingable mop driving module. The two overflow channels clean the mop connected to the swingable mop driving module and the mop connected to the non-swingable mop driving module, respectively.

[0027] In some embodiments of the present application, the at least one liquid outlet channel includes a liquid discharge channel arranged at the bottom end of the liquid storage tank. The cleaning device further comprises a second pump body connected to the liquid discharge channel. The second pump body is used to pump the cleaning liquid in the liquid storage tank out of the liquid discharge channel to the surface to be cleaned.

[0028] In this way, the second pump body can pump the cleaning liquid in the liquid storage tank out of the liquid discharge channel to the surface to be cleaned, so as to clean the mop on the surface to be cleaned.

[0029] In some embodiments of the present application, the dust removal module includes a fan and an air duct. The air duct is in communication with the air inlet end of the fan. The air duct is arranged adjacent to the second tank portion. The wall plate on the side of the second tank portion close to the air duct is a first wall plate. At least part of the first wall plate constitutes the air duct wall of the air duct.

[0030] In this way, the air duct and the second tank portion share a wall, and the structure of the air duct and the second tank portion is more compact, which can further compress the space in the up-down direction of the accommodation space, and ensure the miniaturization of the cleaning device. In addition, when there is airflow passing through the air duct, the airflow will pass through the first wall plate. Since the first wall plate is the side wall of the second tank portion, the cleaning liquid in the second tank portion can cool the airflow, thereby achieving cooling of the fan.

[0031] In some embodiments of the present application, the first wall plate is arranged obliquely. In this way, not only can the relationship between the dust removal module and the second tank portion arranged in the up-down direction be met, but also by reasonably arranging the dust removal module, the dust removal module part can be in contact with the bottom wall of the accommodation space to share the weight of the dust removal module.

[0032] In some embodiments of the present application, the bottom wall of the containing space has a surrounding placement space for accommodating the dust collecting box, the placement space is arranged adjacent to the second box body, the wall plate close to the placement space is the second wall plate, and at least part of the second wall plate constitutes the container wall of the placement space.

[0033] In this way, the placement space and the second box body share a wall, and the structure of the two is more compact, which can further compress the space in the laying direction of the bottom wall of the containing space, and ensure the miniaturization of the cleaning device.

[0034] In some embodiments of the present application, the second wall plate is a flat plate. In this way, the outer wall surface of the dust collecting box can be more flat, which is convenient for processing the dust collecting box.

[0035] In some embodiments of the present application, the placement space is a placement slot with the notch facing upward, and the container wall of the placement slot further comprises a third wall plate, and the second wall plate and the third wall plate are sequentially connected end to end along the circumferential direction of the placement slot.

[0036] In this way, the placement slot is surrounded by the second wall plate and the third wall plate, which can facilitate the taking and placing of the dust collecting box.

[0037] In some embodiments of the present application, along the circumferential direction of the placement slot, the first end of the second wall plate is connected with a first bearing piece, the first end of the third wall plate is connected with a lapping piece, and the lapping piece is lapped on the side surface of the first bearing piece away from the second box body. The second end of the second wall plate is connected with a second bearing piece, and the second end of the third wall plate is connected with an abutting piece abutting on the side surface of the second bearing piece close to the second box body.

[0038] In this way, the third wall plate can be used to position the second wall plate, so as to facilitate the accurate installation of the second wall plate and the accurate installation of the liquid storage tank.

[0039] In some embodiments of the present application, the side surface of the first bearing piece away from the second box body has a avoiding space, and the lapping piece is located in the avoiding space to lap on the first bearing piece.

[0040] In this way, the lapping surface of the lapping piece and the first bearing piece can be more flat, so as to facilitate the flat design of the outer wall surface of the dust collecting box.

[0041] In some embodiments of the present application, the abutting piece comprises an extension part and an abutting part, the extension part is connected with the second end of the third wall plate and extends from the second end of the third wall plate to the side of the second bearing piece close to the second box body. The abutting part is connected to the extension part and abuts on the second bearing piece.

[0042] The abutting piece of such a structure is suitable for a case where a corner exists at the second end of the third wall plate and the second end of the second wall plate, and can facilitate abutment of the abutting piece and the second bearing piece. Since the abutting piece is located entirely on the side of the second bearing piece away from the dust collecting box, the abutting piece can avoid affecting the flatness of the inner wall of the placing groove, thereby facilitating the flat design of the outer wall surface of the dust collecting box.

[0043] In some embodiments of the present application, the liquid storage tank has a first connecting piece connected to the upper wall of the containing space. The liquid storage tank has a second connecting piece connected to the bottom wall of the containing space.

[0044] Through the above arrangement, according to the spatial layout in the containing space, the positions of the first connecting piece and the second connecting piece are reasonably arranged, and the first connecting piece is fixed upward and the second connecting piece is fixed downward, thereby improving the fixing firmness of the liquid storage tank.

[0045] In some embodiments of the present application, the first connecting piece includes a column hole extending upward, and a first fastener is inserted into the column hole to connect the liquid storage tank and the upper wall of the containing space; and / or,

[0046] The second connecting piece includes a fixing plate extending in the horizontal direction, and the fixing plate has a mounting hole through which a second fastener passes to connect the liquid storage tank and the bottom wall of the containing space.

[0047] In this way, the cooperation of the column hole and the first fastener can achieve the connection of the liquid storage tank and the upper wall of the containing space, and the cooperation of the fixing plate extending in the horizontal direction and the second fastener can achieve the connection between the liquid storage tank and the bottom wall of the containing space, thereby reasonably utilizing the fragmented space in the containing space and improving the space utilization.

[0048] In some embodiments of the present application, the outer wall of the cleaning assembly and the inner wall of the containing space enclose a storage space, and the liquid storage tank is filled in the storage space.

[0049] In this way, the liquid storage tank is arranged adjacent to the outer wall of the cleaning assembly and the inner wall of the containing space, which can further improve the space utilization in the up-down direction of the containing space and ensure the miniaturization of the cleaning device.

[0050] In some embodiments of the present application, the liquid storage tank is in surface contact with the cleaning assembly.

[0051] In this way, the cleaning assembly and the liquid storage tank can be closely attached to each other, and the two can be arranged more compactly, thereby further improving the utilization of the containing space.

[0052] In some embodiments of the present application, the cleaning device further includes a mechanical arm assembly arranged in the housing, and when the mechanical arm assembly is accommodated in the containing space, the mechanical arm assembly is located on the front side of the cleaning assembly in the forward direction of the cleaning device.

[0053] In this way, the liquid storage tank is located at the rear of the housing relative to the mechanical arm assembly, so the weight of the mechanical arm assembly and the liquid storage tank can balance each other, the center of gravity of the cleaning device as a whole can be balanced, and the stability of the movement of the cleaning device can be improved.

[0054] The second aspect of the present application provides a cleaning system, comprising the cleaning device in any of the above embodiments and a base station for parking the cleaning device.

[0055] Since the cleaning system in the present application comprises the cleaning device in any of the above embodiments, the same beneficial effects can be achieved. BRIEF DESCRIPTION OF DRAWINGS

[0075] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0076] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects are in an "or" relationship.

[0077] In the description of the embodiments of this application, the technical terms "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the embodiments of this application.

[0078] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0080] The following is a detailed description of this application.

[0081] With the development of technology, cleaning equipment has been widely used in daily life, providing great convenience to people's lives. For example, cleaning equipment can include robot vacuum cleaners and robot vacuum and mop cleaning robots.

[0082] Based on this, this application provides a cleaning system, which includes cleaning equipment and a base station, the base station being used to dock the cleaning equipment.

[0083] It is understandable that the cleaning equipment can be self-moving cleaning equipment, which refers to equipment that automatically performs cleaning operations in a certain area to be cleaned without user operation.

[0084] With the cooperation of base stations and cleaning equipment, the cleaning equipment departs from the base station to carry out cleaning tasks when necessary. After completing the cleaning task, the cleaning equipment docks at the base station, where it can perform operations such as charging, water replenishment, cleaning, and dust collection.

[0085] Based on this, such as Figures 1-3 As shown, this application also provides a cleaning device 01, which includes a housing 1, a cleaning component 2, and a liquid storage tank 3. The housing 1 has an internal receiving space a. The cleaning component 2 is disposed within the receiving space a and includes at least a mop drive module 21. The mop drive module 21 is used to connect to and control the movement of a mop outside the receiving space a for cleaning the surface to be cleaned. The liquid storage tank 3 is disposed within the receiving space a.

[0086] With the above configuration, housing 1 provides a space a for accommodating cleaning component 2 and liquid storage tank 3. Cleaning component 2 can clean the surface to be cleaned, wherein at least one cleaning method is to use mop drive module 21 to drive mop movement to clean the surface. Liquid storage tank 3 can provide cleaning liquid to cleaning component 2 during the cleaning process. Alternatively, liquid storage tank 3 can clean cleaning component 2 itself.

[0087] The housing 1 can be a flat structure, such as a disc-shaped structure or a square-shaped structure. The housing 1 can include an upper shell and a lower shell that are connected to each other. The upper shell is fastened to the lower shell to form a receiving space a, which facilitates the installation and disassembly of components such as the cleaning component 2 and the liquid storage tank 3.

[0088] Furthermore, the mop driven by the mop drive module 21 can be supported on the bottom of the housing 1 and can contact the surface to be cleaned. For example, a cleaning hole can be opened at the bottom of the housing 1, and the cleaning hole can communicate with the receiving space a. The mop can be placed at the cleaning hole, so that the mop drive module 21 can be connected to the mop through the cleaning hole from the receiving space a to control the movement of the mop. For example, the mop can clean the surface to be cleaned by rotating or vibrating.

[0089] In addition to the mop drive module 21, the cleaning component 2 may also include various other functional components, such as the dust removal module 22.

[0090] It is understandable that the liquid storage tank 3 can be used to store any of the following, including water or liquids containing cleaning ingredients, depending on the specific needs.

[0091] In some examples, to facilitate the replenishment of cleaning liquid into the storage tank 3 and the discharge of cleaning liquid from the storage tank 3 for use, the storage tank 3 has an inlet channel B and an outlet channel A. Thus, when the cleaning device 01 is docked at the base station, the base station can replenish the cleaning liquid in the storage tank 3 through the inlet channel B. When the cleaning liquid in the storage tank 3 needs to be used, the cleaning liquid in the storage tank 3 can be discharged through the outlet channel A.

[0092] The use of cleaning liquid in the storage tank 3 may be for wetting the surface to be cleaned or for cleaning the cleaning component 2.

[0093] For example, when the cleaning equipment 01 needs to perform a cleaning task, the cleaning equipment 01 drives out of the base station. During the cleaning process, the cleaning liquid in the storage tank 3 can be discharged from the surface to be cleaned through the liquid outlet channel A so that the mop can clean the surface to be cleaned.

[0094] For example, if the cleaning device 01 is located inside the base station, the cleaning liquid can be discharged through the liquid outlet channel A to the inner side of the mop to clean the inner side of the mop. In this way, by cooperating with the cleaning device for the outer side of the mop inside the base station, the mop can be thoroughly cleaned.

[0095] In some examples, the cleaning device 01 may also include a sensing system, a control system, a motion system (e.g., it may include multiple rollers mounted on the bottom wall of the housing 1 and roller drive devices), an energy system (e.g., it may include a battery), and a human-computer interaction system (e.g., it may include voice control interaction, motion interaction, virtual reality input, etc.). These systems coordinate with the cleaning component 2 and the water tank to enable the cleaning device 01 to move autonomously and perform its cleaning function.

[0096] In related technologies, the various functional components included in the liquid storage tank 3 and the cleaning assembly 2 are all laid on the bottom wall of the accommodating space a, which requires occupying the limited horizontal space of the accommodating space a. As the functions of the cleaning equipment 01 increase, the number of functional components also increases. In order to ensure the miniaturization of the cleaning equipment 01, it is particularly important to improve the utilization rate of the accommodating space a.

[0097] Based on this, such as Figures 1-3 As shown, at least a portion of the liquid storage tank 3 in this application is located below the cleaning component 2.

[0098] Understandably, "below" of cleaning component 2 refers to the side of cleaning component 2 closest to the surface to be cleaned.

[0099] In this way, since at least part of the liquid storage tank 3 is located below the cleaning component 2, the cleaning component 2 and the liquid storage tank 3 are arranged in a stacked manner. This saves horizontal space within the storage space a, providing more horizontal space for other functional components, thereby improving the utilization rate of the storage space a and ensuring the miniaturization of the housing 1, so that the cleaning device 01 can operate in narrow spaces. In addition, since at least part of the liquid storage tank 3 is located below the cleaning component 2, the liquid storage tank 3 contains cleaning liquid, and the overall center of gravity of the cleaning device 01 is lower when the cleaning device 01 moves. This improves the stability of the cleaning device 01 during movement, especially when going through bends or crossing obstacles, where the advantage of the liquid storage tank 3 being located below the cleaning component 2 is even more apparent.

[0100] In some embodiments, such as Figures 1-6 As shown, the cleaning component 2 also includes a dust removal module 22. The liquid storage tank 3 includes a first tank section 31 and a second tank section 32 that are interconnected, and the first tank section 31 and the second tank section 32 are laid on the bottom wall of the receiving space a. At least a portion of the first tank section 31 is located below the mop drive module 21, and the second tank section 32 is located below the dust removal module 22.

[0101] It is understandable that the first box section 31 and the second box section 32 are laid on the bottom wall of the accommodating space a, meaning that the first box section 31 and the second box section 32 are not arranged one above the other.

[0102] With the above arrangement, at least a portion of the first housing 31 is located below the mop drive module 21, and the second housing 32 is located below the dust removal module 22. This conveniently utilizes the space below the mop drive module 21 and the dust removal module 22, further improving the utilization rate of the storage space a and ensuring the miniaturization of the cleaning equipment 01.

[0103] The dust removal module 22 may include components such as an air duct 222 and a fan 221. The air duct 222 is connected to the air inlet of the fan 221, and the air inlet of the air duct 222 can absorb dust from the surface to be cleaned. Thus, when the fan 221 is started, the dust on the surface to be cleaned can enter the air duct 222. In order to collect dust and improve the dust removal effect on the surface to be cleaned, the cleaning device 01 also includes a roller brush and a dust collection box 4. The roller brush is supported on the bottom wall of the housing 1, and the dust collection box 4 is set in the receiving space a. The air inlet of the air duct 222 is connected to the dust collection box 4, and the roller brush is set at the air inlet of the dust collection box 4, and the roller brush can contact the surface to be cleaned. Thus, during dust removal, the roller brush can sweep the dust on the surface to be cleaned by moving relative to the surface to be cleaned. Then, under the action of the fan 221, the dust will enter the dust collection box 4. After the dust collection box 4 has collected a certain amount of dust, the dust in the dust collection box 4 can be cleaned.

[0104] Of course, in other embodiments, the liquid storage tank 3 may simply be located below the mop drive module 21 or the dust removal module 22.

[0105] In some embodiments, such as Figures 1-6 As shown, the number of mop drive modules 21 is at least two, and the at least two mop drive modules 21 include a non-oscillating mop drive module 211 and an oscillating mop drive module 212. At least a portion of the first housing portion 31 is located below the non-oscillating mop drive module 211.

[0106] It is understandable that the non-oscillating mop drive module 211 and the oscillating mop drive module 212 each drive a mop to move. The non-oscillating mop drive module 211 means that the mop it drives does not oscillate in the horizontal plane. The oscillating mop drive module 212 means that the mop it drives can oscillate in the horizontal plane and can swing out into the area covered by the bottom wall of the housing 1. In this way, the mop can clean some corners, edges and other places, which can improve the cleaning degree of the cleaning device 01 on the surface to be cleaned.

[0107] With the above settings, when executing the mopping mode, the non-oscillating mop drive module 211 can drive the corresponding mop to rotate to clean the surface to be cleaned. When cleaning some corners, the oscillating mop drive module 212 can drive the corresponding mop to oscillate beyond the coverage area of ​​the bottom wall of the housing 1 to clean the corners. Since the structure of the non-oscillating mop drive module 211 is simpler than that of the oscillating mop drive module 212 and occupies less horizontal space, the first housing part 31 can be placed below the non-oscillating mop drive module 211, which facilitates the placement of the first housing part 31.

[0108] In other embodiments, both mop drive modules 21 may also be non-oscillating mop drive modules 211, thus allowing the liquid storage tank 3 to be selectively positioned below the two non-oscillating mop drive modules 211.

[0109] In some embodiments, such as Figure 2 , Figure 4 As shown, along the direction approaching the second housing portion 32, the first housing portion 31 includes a remote terminal housing 311, a support sub-housing housing 312, and a connecting sub-housing housing 313 connected in sequence. The connecting sub-housing housing 313 is connected to the second housing portion 32. The support sub-housing housing 312 is disposed below the non-oscillating mop drive module 211.

[0110] Since the position of the non-oscillating mop drive module 211 is relatively fixed, it needs to have a certain gap with the dust removal module 22 and the side wall of the housing 1 to avoid vibration of the non-oscillating mop drive module 211, which would affect the dust removal module 22 and the side wall of the housing 1. Therefore, there may be a certain space on both sides of the non-oscillating mop drive module 211 in the direction close to the second housing part 32. This allows the non-oscillating mop drive module 211 to have a connecting sub-housing 313 on the side close to the second housing part 32 and a remote terminal housing 311 on the side away from the second housing part 32. This not only makes full use of the gap and increases the liquid storage capacity of the liquid storage tank 3, but also ensures the miniaturization of the cleaning equipment 01.

[0111] In some embodiments, such as Figure 2 , 4 As shown, the non-oscillating mop drive module 211 includes a motor 2111 and a transmission unit 2112 connected by a drive mechanism, with the transmission unit 2112 being connected to the mop drive mechanism. The carrier sub-box 312 includes a motor sub-box 3121 and a transmission sub-box 3122 that are interconnected. The motor sub-box 3121 and the transmission sub-box 3122 are laid on the bottom wall of the accommodating space a, with the motor sub-box 3121 located below the motor 2111 and the transmission sub-box 3122 located below the transmission unit 2112.

[0112] In this way, the motor 2111 can drive the mop to move through the transmission unit 2112. Since the motor 2111 and the transmission unit 2112 are laid flat, the non-oscillating mop drive module 211 can be prevented from being too high, and the height of the housing 1 can be controlled. On this basis, a motor sub-box 3121 is set below the motor 2111, and a transmission sub-box 3122 is set below the transmission unit 2112 to improve space utilization.

[0113] The transmission unit 2112 may include a housing and a plurality of gears that mesh sequentially in a horizontal direction within the housing. The output shaft of the motor 2111 and a gear adjacent to it are coaxially arranged, and the mop and a gear adjacent to it are coaxially arranged. Thus, when the motor 2111 is started, it drives the plurality of gears to rotate sequentially, thereby driving the mop to rotate in order to clean the surface to be cleaned.

[0114] Of course, the transmission unit 2112 may also include a pulley structure, through which the motor 2111 drives the mop.

[0115] In some embodiments, such as Figure 6 As shown, the motor sub-box 3121 has a disc-shaped structure, and the upper surface of the disc-shaped structure is in contact with the lower end face of the motor 2111. Since the disc-shaped structure can contact the end face of the motor 2111, the cleaning liquid inside the disc-shaped structure can be used to dissipate heat from the motor 2111.

[0116] In some embodiments, such as Figure 4 , Figure 5 As shown, the upper end of the remote terminal housing 311 is lower than the upper end of the non-oscillating mop drive module 211. In this way, when the upper end of the non-oscillating mop drive module 211 contacts the upper wall of the receiving space a, interference between the remote terminal housing 311 and the upper wall of the receiving space a can be avoided, which facilitates the installation of the housing 1 and the remote terminal housing 311.

[0117] In other embodiments, the upper end of the remote terminal housing 311 is flush with the upper end of the non-oscillating mop drive module 211. Thus, when the upper end of the non-oscillating mop drive module 211 contacts the upper wall of the receiving space a, not only is interference from the remote terminal housing 311 to the upper wall of the receiving space a avoided, facilitating the installation of the housing 1 and the remote terminal housing 311, but also increasing the liquid storage capacity of the liquid storage tank 3 and improving space utilization.

[0118] In cases where the upper end of the motor 2111 is higher than the upper end of the transmission unit 2112, the upper end of the remote terminal housing 311 is lower than or level with the upper end of the motor 2111. In cases where the upper end of the transmission unit 2112 is higher than the upper end of the motor 2111, the upper end of the remote terminal housing 311 is lower than or level with the upper end of the transmission unit 2112.

[0119] In some embodiments, such as Figure 6 As shown, the liquid storage tank 3 has at least one liquid outlet channel A and a liquid inlet channel B, and at least one of the liquid outlet channel A and the liquid inlet channel B is disposed in the remote terminal box 311 and / or connected to the sub-box 313.

[0120] With the above configuration, when the cleaning device 01 is docked at the base station, the base station can replenish the cleaning liquid in the storage tank 3 through the liquid inlet channel B. When the cleaning liquid in the storage tank 3 needs to be used, the cleaning liquid in the storage tank 3 can be discharged through the liquid outlet channel A. Since the cleaning component 2 is not located above the remote terminal box 311 and the connecting sub-box 313, setting at least one liquid outlet channel A and liquid inlet channel B on the remote terminal box 311 and / or the connecting sub-box 313 facilitates the installation of the liquid outlet channel A and the liquid inlet channel B.

[0121] Based on this, in some embodiments, such as Figure 6 As shown, at least one liquid outlet channel A includes an overflow channel A1 disposed at the upper end of the liquid storage tank 3. The cleaning device 01 also includes a first pump body connected to the liquid inlet channel B, the first pump body being used to pump cleaning liquid into the liquid storage tank 3 and to allow the cleaning liquid to overflow from the overflow channel A1 to the mop connected to the mop drive module 21.

[0122] In this way, after the first pump body fills the liquid storage tank 3 with enough cleaning liquid, the cleaning liquid continues to be introduced. The excess cleaning liquid can overflow from the overflow channel A1 to the mop connected to the mop drive module 21 to clean the mop connected to the mop drive module 21. The first pump body is used as a power source to realize the filling of the liquid storage tank 3 and the cleaning of the mop connected to the mop drive module 21.

[0123] The overflow channel A1 can extend horizontally, which not only saves vertical space within the containment space a, but also facilitates the outflow of clean liquid from the overflow channel A1.

[0124] Alternatively, the overflow channel A1 can be connected to the mop to which the mop drive module 21 is connected via a pipe. Alternatively, the length of the overflow channel A1 can be extended so that the liquid channel is directly connected to the mop to which the mop drive module 21 is connected.

[0125] In some embodiments, such as Figures 1-6 As shown, the swingable mop drive module 212 is located on the side of the dust removal module 22 away from the non-swingable mop drive module 211. There are at least two overflow channels A1, including a first overflow channel A11 and a second overflow channel A12. The first overflow channel A11 is located in the remote terminal housing 311, and the cleaning liquid in the storage tank 3 can overflow through the first overflow channel A11 to the mop connected to the non-swingable mop drive module 211. The second overflow channel A12 is located in the connecting sub-housing housing 313, and the cleaning liquid in the storage tank 3 can overflow through the second overflow channel A12 to the mop connected to the swingable mop drive module 212.

[0126] It should be explained that the mop connected to the non-oscillating mop drive module 211 is located at the position of the non-oscillating mop drive module 211, and the mop connected to the oscillating mop drive module 212 is located at the position of the oscillating mop drive module 212. Therefore, it can be considered that the oscillating mop drive module 212 is located on the side of the dust removal module 22 away from the non-oscillating mop drive module 211, and the mop connected to the oscillating mop drive module 212 is located on the side of the dust removal module 22 away from the mop connected to the non-oscillating mop drive module 211.

[0127] With this configuration, since the swingable mop drive module 212 is located on the side of the dust removal module 22 away from the non-swingable mop drive module 211, and the connecting sub-box 313 is closest to the second box 32, the connecting sub-box 313 is closer to the mop connected to the swingable mop drive module 212. Thus, by placing the first overflow channel A11 in the connecting sub-box 313, the cleaning liquid from the first overflow channel A11 can easily flow to the mop connected to the swingable mop drive module 212. The two overflow channels A1 respectively clean the mop connected to the swingable mop drive module 212 and the mop connected to the non-swingable mop drive module 211, which can meet the cleaning requirements.

[0128] In this process, when cleaning the mop, the cleaning liquid in the liquid tank 3 can clean only the inner surface of the mop, while the outer surface of the mop can be cleaned by the base station.

[0129] In some embodiments, such as Figure 6 As shown, at least one liquid outlet channel A includes a drain channel A2 located at the bottom of the liquid storage tank 3. The cleaning device 01 also includes a second pump body connected to the drain channel A2. The second pump body is used to pump the cleaning liquid in the liquid storage tank 3 out through the drain channel A2 to the surface to be cleaned. With this configuration, when the cleaning device 01 performs a cleaning task, the second pump body can pump the cleaning liquid in the liquid storage tank 3 to the surface to be cleaned, so that the mop can clean the surface to be cleaned.

[0130] It is understandable that the second pump can act as a shut-off valve. When the cleaning liquid needs to be discharged through the drain channel A2 and the cleaning liquid needs to be overflowed through the overflow channel A1, the second pump can be turned off and the first pump can be started. When the first pump pumps the cleaning liquid into the storage tank 3 and the storage tank 3 is full or nearly full, the first pump continues to pump the cleaning liquid. In this way, the excess cleaning liquid will overflow from the overflow channel A1 to clean the mop.

[0131] A nozzle can be connected to the outlet end of the drainage channel A2, with the nozzle facing the surface to be cleaned. The presence of the nozzle ensures that the cleaning liquid is sprayed evenly onto the surface to be cleaned.

[0132] In some embodiments, such as Figure 7 As shown, the dust removal module 22 includes a fan 221 and an air duct 222. The air duct 222 is connected to the air inlet of the fan 221. The air duct 222 is arranged adjacent to the second housing part 32, and the wall panel of the second housing part 32 near the air duct 222 is the first wall panel 321. At least a portion of the first wall panel 321 constitutes the air duct wall of the air duct 222.

[0133] In this way, the air duct 222 and the second housing 32 share a wall, which makes their structure more compact and further reduces the vertical space of the housing a, ensuring the miniaturization of the cleaning equipment 01. In addition, when airflow passes through the air duct 222, the airflow passes through the first wall panel 321. Since the first wall panel 321 is the side wall of the second housing 32, the cleaning liquid in the second housing 32 can cool the airflow, thereby cooling the fan 221.

[0134] In some embodiments, such as Figure 7 As shown, the first wall panel 321 is inclined. This not only satisfies the vertical relationship between the dust removal module 22 and the second housing 32, but also, through a reasonable layout, allows part of the dust removal module 22 (e.g., part of the fan 221) to contact the bottom wall of the accommodating space a, so as to share the weight of the dust removal module 22 and prevent the liquid storage tank 3 from being squeezed.

[0135] In some embodiments, such as Figure 7 As shown, the bottom wall of the accommodating space a has an enclosed placement space b, which is used to accommodate the dust collection box 4. The placement space b is arranged adjacent to the second box part 32. The wall panel of the second box part 32 near the placement space b is the second wall panel 322. At least a portion of the second wall panel 322 constitutes the container wall of the placement space b.

[0136] With this arrangement, the placement space b and the second box part 32 share the same wall, which makes the structure of the two more compact and can further compress the space in the flat direction of the bottom wall of the accommodating space a, ensuring the miniaturization of the cleaning equipment 01.

[0137] In some embodiments, such as Figure 6 , Figure 7 As shown, the second wall panel 322 is a flat plate. This makes the inner wall surface of the placement space b corresponding to the second wall panel 322 flatter, which can ensure that the outer wall surface of the dust collection box 4 opposite to the second wall panel 322 is flatter, thus facilitating the processing and production of the dust collection box 4.

[0138] Of course, in other embodiments, the second wall panel 322 may also be a bent or curved panel.

[0139] In some embodiments, such as Figure 8As shown, the placement space b is a placement groove with the opening facing upwards. The container wall of the placement groove also includes a third wall plate 5. Along the circumference of the placement groove, the second wall plate 322 and the third wall plate 5 are connected end to end in sequence.

[0140] It is understandable that the placement trough is formed by the bottom wall of the accommodating space a, the second wall panel 322 and the third wall panel 5. The bottom wall of the accommodating space a is the bottom of the placement trough, and the second wall panel 322 and the third wall panel 5 are the peripheral walls of the placement trough.

[0141] The second wall panel 322 and the third wall panel 5 form the perimeter of the placement groove, and the groove opening faces upwards to facilitate the removal and placement of the dust collection box 4.

[0142] The inner wall of the placement slot needs to be compatible with the outer wall of the dust collection box 4. This not only ensures the stable setting of the dust collection box 4, but also facilitates the placement and removal of the dust collection box 4.

[0143] In some embodiments, such as Figures 8-10 As shown, along the circumference of the placement groove, the first end of the second wall panel 322 is connected to a first support member 3221, and the first end of the third wall panel 5 is connected to an overlapping member 51, which overlaps the surface of the first support member 3221 away from the second housing portion 32. The second end of the second wall panel 322 is connected to a second support member 3222, and the second end of the third wall panel 5 is connected to an abutting member 52, which abuts against the surface of the second support member 3222 near the second housing portion 32.

[0144] With this configuration, when forming the placement slot, the third wall panel 5 can be connected to the bottom wall of the receiving space a first. At this time, there is space between the first and second ends of the third wall panel 5 for installing the second wall panel 322. Then, the liquid storage tank 3 is placed directly in the receiving space a, and the second wall panel 322 is inserted between the first and second ends of the third wall panel 5. At the same time, the overlapping member 51 overlaps with the first bearing member 3221, and the abutting member 52 abuts against the second bearing member 3222. In this way, the third wall panel 5 can be used to position the second wall panel 322, so as to facilitate the accurate installation of the second wall panel 322 and the accurate installation of the liquid storage tank 3.

[0145] It should be explained that the first end of the second wall panel 322 is adjacent to the first end of the third wall panel 5, and the second end of the second wall panel 322 is adjacent to the second end of the third wall panel 5.

[0146] The first support member 3221 may be part of the second wall panel 322, or the first support member 3221 may also be an external component connected to the second wall panel 322. Similarly, the second support member 3222 may be part of the second wall panel 322, or the second support member 3222 may also be an external component connected to the second wall panel 322.

[0147] Furthermore, the first support member 3221 can be a straight plate structure or a curved plate structure. Similarly, the second support member 3222 can be a straight plate structure or a curved plate structure.

[0148] Furthermore, the lap joint 51 can be a plate-like structure or a block-like structure, etc.

[0149] Of course, the first end of the second wall panel 322 can also be directly connected to the first end of the third wall panel 5, and the second end of the second wall panel 322 can also be directly connected to the second end of the third wall panel 5.

[0150] In some embodiments, such as Figure 9 As shown, the first support member 3221 has a clearance space c on the side surface away from the second housing part 32, and the overlapping member 51 is located in the clearance space c to overlap the first support member 3221. This makes the overlapping surface of the overlapping member 51 and the first support member 3221 relatively flat, so as to facilitate the flat design of the outer wall surface of the dust collection box 4.

[0151] In some examples, along the direction in which the overlap 51 overlaps the first support member 3221, the size of the clearance space c is the same as the size of the overlap 51. This makes the overlap position of the overlap 51 and the first support member flat, which facilitates the flattening design of the outer wall of the dust collection box 4.

[0152] In some embodiments, such as Figure 10 As shown, the abutting member 52 includes an extension portion 521 and an abutting portion 522. The extension portion 521 is connected to the second end of the third wall panel 5 and extends from the second end of the third wall panel 5 toward the side of the second support member 3222 near the second housing portion 32. The abutting portion 522 is connected to the extension portion 521 and abuts against the second support member 3222.

[0153] It is understandable that the abutting portion 522 is connected to the portion of the extension portion 521 that extends to the side of the second carrier 3222 near the second housing portion 32.

[0154] In this way, the extension portion 521 can be used to connect the abutment portion 522 to the third wall panel 5, and the abutment portion 522 can abut against the second support member 3222. This type of abutment member 52 is suitable for situations where there is a corner between the second end of the third wall panel 5 and the second end of the second wall panel 322, which facilitates the abutment member 52 abutting against the second support member 3222. Furthermore, since the abutment member 52 is located entirely on the side of the second support member 3222 away from the dust collection box 4, it can avoid affecting the flatness of the inner wall of the placement slot, thereby facilitating the flat design of the outer wall surface of the dust collection box 4.

[0155] Of course, the abutment 52 can also be a straight plate structure, directly connected to the second end of the third wall panel 5.

[0156] In some embodiments, such as Figure 6 As shown, the liquid storage tank 3 has a first connector 33, which is connected to the upper wall of the receiving space a. The liquid storage tank 3 also has a second connector 34, which is connected to the bottom wall of the receiving space a.

[0157] With the above settings, the positions of the first connector 33 and the second connector 34 are reasonably set according to the spatial layout within the accommodating space a. By fixing the first connector 33 upward and the second connector 34 downward, the stability of the liquid storage tank 3 is improved.

[0158] The first connector 33 and the second connector 34 are both located on the peripheral wall of the liquid storage tank 3. This arrangement ensures that the first connector 33 and the second connector 34 will not interfere with the cleaning component 2, which facilitates the installation of the cleaning component 2 and the connection between the first connector 33 and the second connector 34 and the inner wall (shell 1) of the accommodating space a.

[0159] In some embodiments, such as Figure 6 As shown, the first connector 33 includes an upwardly extending post hole, into which a first fastener extends to connect the liquid storage tank 3 to the upper wall of the receiving space a.

[0160] This design ensures the secure fixing of the liquid storage tank 3. Furthermore, since the column hole is fixed upwards, a first through hole is made on the upper wall of the receiving space a during the actual fixing process. The first fastener passes through the first through hole from top to bottom and extends into the column hole. During installation, the upper surface of the column hole provides support to the upper wall of the receiving space a, facilitating the proper installation of the first fastener.

[0161] The first fastener can be a screw or bolt, etc.

[0162] In other embodiments, such as Figure 6 As shown, the second connector 34 includes a fixing plate extending in the horizontal direction, the fixing plate having mounting holes through which a second fastener passes to connect the liquid storage tank 3 to the bottom wall of the receiving space a. The second fastener can be a screw or bolt, etc.

[0163] This design ensures the secure fixing of the liquid storage tank 3. Furthermore, since the fixing plate is fixed downwards, during the actual fixing process, the second fastener passes through the mounting hole from top to bottom and is fixed to the bottom wall of the receiving space a. In this case, to facilitate the fixing of the second fastener, a columnar hole can be provided on the bottom wall of the receiving space a, with the upper end face of the columnar hole abutting against the bottom surface of the mounting plate. The second fastener passes through the mounting hole and the columnar hole sequentially from top to bottom to achieve the connection. The upper end face of the columnar hole provides support for the mounting plate, making it easy to stably fix the fixing plate to the bottom wall of the receiving space a using the second fastener.

[0164] In other embodiments, such as Figure 6 As shown, the first connector 33 includes an upwardly extending post hole into which a first fastener extends to connect the liquid storage tank 3 to the upper wall of the receiving space a. The second connector 34 includes a horizontally extending fixing plate with mounting holes through which a second fastener passes to connect the liquid storage tank 3 to the bottom wall of the receiving space a.

[0165] With this configuration, the combination of the column hole and the fastener allows the liquid storage tank 3 to be connected to the upper wall of the containing space a, and the combination of the horizontally extended fixing plate and the fastener allows the liquid storage tank 3 to be connected to the bottom wall of the containing space a. This allows for the rational use of the fragmented space within the containing space a and improves space utilization.

[0166] Of course, in other embodiments, the liquid storage tank 3 can also be fixed in the receiving space a by other suitable means, such as by bonding or snap-fitting.

[0167] In some embodiments, the outer wall of the cleaning component 2 and the inner wall of the receiving space a form a storage space, and the liquid storage tank 3 is filled in the storage space.

[0168] By setting the liquid storage tank 3 adjacent to the outer wall of the cleaning component 2 and the inner wall of the containing space a, the space utilization rate of the containing space a in the vertical direction can be further improved, ensuring the miniaturization of the cleaning equipment 01.

[0169] In some embodiments, the surfaces of the reservoir 3 and the cleaning component 2 are in contact with each other. This allows the cleaning component 2 and the reservoir 3 to fit together tightly, making their arrangement more compact and further improving the utilization of the storage space a.

[0170] In some examples, the housing of the drive unit is in close contact with the outer wall of the drive sub-box.

[0171] In some embodiments, such as Figure 1 , Figure 3As shown, the cleaning device 01 also includes a robotic arm assembly 6 disposed in the housing 1. When the robotic arm assembly 6 is housed in the receiving space a, the robotic arm assembly 6 is located in front of the cleaning assembly 2 along the forward direction of the cleaning device 01.

[0172] It is understandable that the robotic arm assembly 6 has a gripper. When the robotic arm assembly 6 needs to work, it is controlled to extend from the receiving space a to the outside and then pick up medium or large objects. When the robotic arm assembly 6 does not need to work, it is stored in the receiving space a.

[0173] By setting up the robotic arm assembly 6, it is possible to clean medium or large debris. Since the robotic arm assembly 6 requires horizontal space within the accommodating space a, placing the liquid storage tank 3 below the cleaning assembly 2 saves horizontal space within the accommodating space a, freeing up space for the robotic arm assembly 6. This also ensures sufficient liquid storage capacity in the tank 3, resulting in a more rational spatial layout within the accommodating space a.

[0174] In addition, since the liquid storage tank 3 is located behind the housing 1 relative to the robotic arm assembly 6, the weight of the robotic arm assembly 6 and the weight of the liquid storage tank 3 can be balanced back to back, so that the center of gravity of the cleaning equipment 01 is balanced as a whole, which can improve the stability of the movement of the cleaning equipment 01. This advantage is even more prominent when the cleaning equipment 01 turns or crosses obstacles.

[0175] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
