Description

TECHNICAL FIELD

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

[0002] The cleaning equipment has advantages of environmental protection, energy saving, high efficiency and the like. With the increasing awareness of household cleaning efficiency, the cleaning equipment has been gradually widely applied in daily production and life.

[0003] The cleaning equipment, for example, a mopping cleaning equipment, contacts different types of ground surfaces, such as cement ground surfaces, wooden ground surfaces and ceramic ground surfaces, and also contacts objects placed on the ground surfaces, especially carpets and blankets with very low heights, during use.

[0004] However, for carpets or blankets that do not need to be cleaned, the cleaning equipment will stain and attach water stains on the carpets or blankets during the cleaning process, which is easy to dirty the carpets or blankets and affects the use experience of users. CONTENT OF THE UTILITY MODEL

[0005] The embodiments of the present application provide a cleaning equipment and a cleaning system, and aim to solve the technical problem in the related art that the cleaning equipment will stain and attach water stains on carpets or blankets during the cleaning process, which is easy to dirty the carpets or blankets and affects the use experience of users.

[0006] In a first aspect, the embodiments of the present application provide a cleaning equipment, comprising a device main body, a cleaning piece, a shielding piece and a driving piece.

[0007] The shielding piece is located at least on one side of the cleaning piece facing a to-be-cleaned surface.

[0008] The fixed end of the driving piece is connected with the device main body, and the output end of the driving piece is movably connected with the shielding piece.

[0009] The driving piece is used to drive at least part of the shielding piece to move relative to the device main body along a first direction until the shielding piece is located between the cleaning piece and the to-be-cleaned surface in a second direction, and the first direction intersects the second direction.

[0010] The cleaning device provided by the embodiments of the present application can shield the cleaning element during the cleaning process by arranging the shielding element and the cooperating driving element, isolate the cleaning element from the surface to be cleaned, effectively avoid the cleaning device from staining the carpet or the blanket and the like objects that do not need to be cleaned with water stains, dirt and the like during the cleaning process, and thus improve the cleaning effect and user experience of the cleaning device. In addition, the driving element can automatically adjust the position of the shielding element, and automatically shield and unshield the cleaning element. The above intelligent control method can reduce manual intervention, and has relatively high precision compared with manual operation, and thus can improve the cleaning efficiency and quality of the cleaning device.

[0011] In the above cleaning device, optionally, the first direction is perpendicular to the second direction,

[0012] In the second direction, the orthogonal projection of the shielding element on the surface to be cleaned at least covers the orthogonal projection of the cleaning element on the surface to be cleaned.

[0013] Through the above arrangement, when the orthogonal projection of the shielding element at least covers the orthogonal projection of the cleaning element, the shielding element can completely block the contact between the cleaning element and the surface to be cleaned in the horizontal direction regardless of the shape and size of the cleaning element, and ensure that the water stains, dirt and the like on the cleaning element cannot be stained on the objects that do not need to be cleaned, effectively solve the problems existing in the prior art, and improve the cleaning effect and user experience of the cleaning device.

[0014] In the above cleaning device, optionally, the cleaning element includes a contact portion and a non-contact portion connected to each other, and the contact portion is used to contact the surface to be cleaned;

[0015] In the second direction, the orthogonal projection of the shielding element on the surface to be cleaned at least covers the orthogonal projection of the contact portion on the surface to be cleaned.

[0016] Through the above arrangement, when the area to be cleaned appears during the cleaning process, the driving element can control the shielding element to move, so that the contact portion can accurately contact the surface to be cleaned and effectively perform the cleaning operation. When the carpet or the blanket and the like objects that do not need to be cleaned are encountered, the shielding element can return to the original position and accurately shield the contact portion, so that the cleaning device only cleans the area to be cleaned, avoids the mis-cleaning of the objects that do not need to be cleaned, and further improves the cleaning effect and user experience of the cleaning device.

[0017] In the above cleaning device, optionally, the shielding element includes a first support rod and a flexible shielding portion,

[0018] The fixed end of the flexible shielding portion is connected to the first support rod, and the movable end of the flexible shielding portion is wound on the first support rod;

[0019] The first supporting rod is fixedly connected with an output end of the driving member;

[0020] The driving member is used for driving the first supporting rod to rotate and drive the flexible shielding part to expand, so as to drive the movable end of the flexible shielding part to move along the first direction.

[0021] By the above arrangement, the cleaning device drives the flexible shielding part to expand by driving the first supporting rod to rotate, which can fully utilize the flexibility and deformability of the flexible shielding part, so that the flexible shielding part can adapt to different space and position requirements in the expansion process, and accurate shielding of the cleaning member is realized. The movable end of the flexible shielding part moves along the first direction to ensure that the shielding member can be accurately located between the cleaning member and the surface to be cleaned after expansion, effectively preventing water stains, dirt and the like on the cleaning member from adhering to carpets, blankets and the like that do not need to be cleaned, and improving the cleaning effect and user experience of the cleaning device.

[0022] In the above cleaning device, optionally, a guide member extending along the first direction is further included;

[0023] The side of the guide member facing the cleaning member is connected with the movable end of the flexible shielding part, and the side of the guide member away from the cleaning member is connected with the output end of the driving member.

[0024] By the above arrangement, the movable end of the flexible shielding part can move linearly along the extension direction of the guide member, avoiding shaking or deviation during movement, ensuring that the shielding member can accurately form an effective shielding between the cleaning member and the surface to be cleaned, preventing water stains, dirt and the like on the cleaning member from adhering to carpets or blankets that do not need to be cleaned, and improving the cleaning effect and user experience of the cleaning device.

[0025] In the above cleaning device, optionally, a limiting member is further included,

[0026] The limiting member is located on the side of the first supporting rod away from the guide member, the limiting member has a limiting cavity, and the first supporting rod is rotationally arranged in the limiting cavity.

[0027] By the above arrangement, the limiting member and the guide member can constrain and support the first supporting rod from different directions to form a stable structure. The limiting member is located on the side of the first supporting rod away from the guide member, which can effectively prevent the first supporting rod from deviating or shaking to this side during rotation, thereby improving the rotation accuracy and stability of the first supporting rod.

[0028] The limiting cavity can limit and guide the rotation of the first supporting rod, ensuring that the rotation direction and position of the first supporting rod are accurate and reliable, and improving the stability and reliability of the cleaning device. At the same time, the rotation of the first supporting rod in the limiting cavity can also reduce friction and resistance during rotation, prolonging the service life of the device.

[0029] In the cleaning device, optionally, the guide member comprises:

[0030] a rack, the rack is connected with the movable end of the flexible shielding part towards one side of the cleaning member, and the rack is in transmission connection with the output end of the driving member away from one side of the cleaning member;

[0031] a track, the rack is slidingly arranged on the track, and the track is connected with the fixed end of the driving member.

[0032] Through the above arrangement, the track provides stable support for the rack, ensuring the position accuracy and stability of the rack during movement, avoiding transmission errors or shielding failures caused by rack shaking or deviation.

[0033] In addition, connecting the rack with the movable end of the flexible shielding part can synchronize the movement of the flexible shielding part with the movement of the rack. When the driving member drives the rack to move in the first direction, the movable end of the flexible shielding part will move accordingly, thereby realizing the shielding or unshielding function of the cleaning member.

[0034] Secondly, the rotation of the driving member can be converted into the linear motion of the rack through the meshing of the gear and the rack, thereby driving the flexible shielding part to move in the first direction, realizing the expansion and retraction of the shielding member. The transmission of the gear and the rack has the advantages of high transmission accuracy, stable transmission ratio and large carrying capacity, which can ensure the speed and position accuracy of the rack during movement, and improve the reliability and stability of the whole shielding system.

[0035] In the cleaning device, optionally, the guide member further comprises a first gear and a second gear, both the first gear and the second gear are connected with the output end;

[0036] The first gear is in meshing with the rack, and the second gear is sleeved on the end of the first support rod, and the second gear is in rotary connection with the device body.

[0037] Through the above arrangement, the first gear is in meshing with the rack, which can convert the rotary motion of the driving member into the linear motion of the rack, thereby driving the flexible shielding part to move in the first direction, realizing the expansion and retraction of the shielding member;

[0038] The second gear is sleeved on the end of the first support rod and is in rotary connection with the device body, which can limit and guide the rotation of the first support rod, ensuring the stability and accuracy of the first support rod during rotation. The above design makes the guide member not only have the function of guiding, but also have the functions of power transmission and motion conversion, which improves the overall performance and working efficiency of the cleaning device.

[0039] In the cleaning device, optionally, the guide member further comprises:

[0040] The fixed rod is connected with the movable end of the flexible shielding part and the side of the rack facing the cleaning part.

[0041] Through the above arrangement, the fixed rod can effectively connect the movable end of the flexible shielding part and the rack, ensure the relative position and movement relationship between the two, and improve the stability and precision of the entire shielding system. In addition, the fixed rod can also play a supporting and guiding role, reduce the shaking and deviation of the flexible shielding part and the rack during movement, and further improve the performance and service life of the cleaning device.

[0042] In the cleaning device, optionally, the guide member further comprises an auxiliary rod and a third gear, the third gear is sleeved on the auxiliary rod, the auxiliary rod is arranged in a spaced manner with the support rod, and the third gear is engaged with the second gear.

[0043] The auxiliary rod can provide stable support for the third gear, so that the auxiliary rod can be accurately engaged with the second gear to realize power transmission and conversion. At the same time, the engagement of the third gear and the second gear can form a gear transmission system, which transmits the rotation of the second gear to the third gear, thereby driving the movement of the auxiliary rod and related components, realizing the rotation control of the first support rod, and improving the stability and reliability of the entire shielding system.

[0044] In the cleaning device, optionally, in the first direction,

[0045] The shielding member is located on one side of the cleaning part, or the number of shielding members is multiple, multiple shielding members are respectively located on different sides of the cleaning part, and multiple shielding members are all moved towards the cleaning part.

[0046] The shielding member is located on one side of the cleaning part, which is also conducive to simplifying the structure and movement mode of the shielding member, reducing the interference between the shielding member and the cleaning part, and improving the overall stability and reliability of the cleaning device.

[0047] In a second aspect, the embodiments of the present application also provide a cleaning system, comprising a base station and the cleaning device, and the base station is used for docking the cleaning device.

These drawings and the written description are not intended to restrict the scope of the present application concept in any way, but to illustrate the present application concept to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0068] In the related art, during the cleaning process, the cleaning robot may pass through a carpet or a blanket. At this time, water stains, dirt and the like attached to the cleaning device may be stained and attached to the carpet or the blanket, which may easily dirty the carpet or the blanket and affect the user experience.

[0069] Based on the above technical problems, the embodiments of the present application provide a cleaning device and a cleaning system. The cleaning device comprises a device main body, a cleaning piece, a shielding piece and a driving piece. The shielding piece is located at least on one side of the cleaning piece facing a to-be-cleaned surface. The fixed end of the driving piece is connected with the device main body, and the output end of the driving piece is movably connected with the shielding piece. The driving piece is used to drive at least part of the shielding piece to move relative to the device main body in a first direction until the shielding piece is located between the cleaning piece and the to-be-cleaned surface in a second direction. The first direction intersects the second direction.

[0070] The cleaning device and the cleaning system provided by the embodiments of the present application can shield the cleaning piece during the cleaning process by setting the shielding piece and the cooperating driving piece, realize the isolation between the cleaning piece and the to-be-cleaned surface, effectively avoid the cleaning device from staining water stains, dirt and the like to the carpet or the blanket and the like which do not need to be cleaned during the cleaning process, and thus improve the cleaning effect and the user experience of the cleaning device. In addition, the driving piece can automatically adjust the position of the shielding piece, realize the automatic shielding and unshielding of the cleaning piece. The above intelligent control mode can reduce manual intervention, has relatively high precision compared with manual operation, and thus can improve the cleaning efficiency and the quality of the cleaning device and the cleaning system.

[0071] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described below in a more detailed manner with reference to the drawings in the preferred embodiments of the present application. Identical or similar reference numerals are used to represent identical or similar components throughout the drawings. The described embodiments are part of the device embodiments of the present application, rather than the whole device embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application. The embodiments of the present application will be described in detail below with reference to the drawings.

[0072] In a first aspect, the embodiments of the present application provide a cleaning system (not shown in the figure), which comprises a base station and a cleaning device 10, and the base station is used for docking the cleaning device 10.

[0073] It can be understood that after the cleaning device 10 completes cleaning of the cleaning surface, the cleaning device 10 can be placed on the base station for positioning, charging, self-cleaning, drying or water supply and drainage. The base station is provided with a placement position of the cleaning device 10, so that the positioning of the cleaning device 10 can be realized. The base station is provided with a charging interface, so that the charging of the cleaning device 10 can be realized. The base station can be provided with a water inlet pipe and a sewage outlet pipe to supply water to the clean water tank of the cleaning device 10 and drain water from the sewage tank. The base station can be provided with a drying device for drying the cleaning components of the cleaned cleaning device 10.

[0074] It should be noted that the base station generally needs to be placed on the ground to support the operation of the cleaning device 10.

[0075] It can be understood that the cleaning device 10 can be different types of devices. For example, the cleaning device 10 can be a sweeping robot, a mopping robot, a sweeping and mopping integrated robot, a scrubber or the like. Different types of cleaning devices 10 have corresponding base stations.

[0076] The following will be described taking the cleaning device 10 as a sweeping and mopping integrated robot as an example.

[0077] Referring to Figure 1 and Figure 2 In a second aspect, the embodiments of the present application also provide a cleaning device 10, which comprises a device main body 100, cleaning components 200 and driving components 400.

[0078] The device body 100 serves as a basic support structure, carries and connects other components, and ensures the overall stability and coordination of the device. For example, the device body 100 is connected with the cleaning member 200, and the device body 100 can support the rotation of the cleaning member 200. The cleaning member 200 can rotate relative to the device body 100 to clean the surface to be cleaned.

[0079] It can be understood that the cleaning member 200 is directly in contact with the ground, and the cleaning member 200 can include but is not limited to a rolling brush, a track, a mop, a brush, etc., responsible for adsorbing dust and stains.

[0080] It can be understood that when the cleaning device 10 is a sweeping and mopping integrated robot, the sweeping and mopping integrated robot can be docked with the base station when the cleaning operation is not performed, so as to realize the functions such as self-cleaning, charging, water supply and drainage, etc.

[0081] It should be noted that when the cleaning device 10 is a sweeping and mopping integrated robot, the cleaning member 200 can be a mop, and the mop can rotate relative to the device body 100 to clean the surface to be cleaned. The style of the cleaning member 200 can also be various, such as a track type, a rolling type, etc., and the embodiments of the present application do not limit the above examples.

[0082] Further, when the cleaning device 10 is a sweeping and mopping integrated robot, in order to ensure that the cleaning device 10 can effectively clean the surface to be cleaned, the cleaning member 200 can need to be in contact with a liquid. The above-mentioned liquid includes but is not limited to a cleaning liquid used for cleaning, water, or a contaminated liquid such as sewage, dirty oil, etc. on the surface to be cleaned.

[0083] On the other hand, as the cleaning operation of the cleaning device 10 is performed, water stains, dirt, etc. can gradually adhere to the cleaning member 200. However, the surface to be cleaned can also have various possibilities, including but not limited to a cement ground, a ceramic tile ground, and a blanket, a carpet, etc. on the ground.

[0084] It should be noted that the blanket and the carpet are generally not desired to be wet, but in the cleaning operation, the water stains, dirt, etc. adhered to the cleaning member 200 can fall on the blanket and the carpet.

[0085] Reference Figures 3-6 Therefore, in some embodiments, the cleaning device 10 includes a shielding member 300. When the cleaning device 10 encounters a blanket or a carpet, etc. which is not desired to be wet, the shielding member 300 can be extended to block the contact between the cleaning member 200 and the above-mentioned object, prevent the water stains, dirt, etc. on the cleaning member 200 from staining the object, avoid polluting these objects, and improve the cleaning effect and user experience of the cleaning device 10.

[0086] The fixed end of the driving member 400 is connected with the device body 100, the fixed end of the driving member 400 is connected with the device body 100, and the position of the driving member 400 is fixed relative to the device body 100 during operation, thereby providing a foundation support for stable operation of the driving member 400.

[0087] The output end of the driving member 400 is movably connected with the shielding member 300, so that the driving member 400 can transmit power to the shielding member 300, drive the shielding member 300 to move relative to the device body 100, and allow the shielding member 300 to adjust its position and posture within a certain range according to actual needs.

[0088] The driving member 400 is used to drive at least part of the shielding member 300 to move relative to the device body 100 along a first direction X until the shielding member 300 is located between the cleaning member 200 and the surface to be cleaned in a second direction Y, and the first direction X intersects the second direction Y. That is, the shielding member 300 can move according to a predetermined direction and path under the action of the driving member 400, so as to realize precise shielding and unshielding of the cleaning member 200.

[0089] It should be noted that the driving member 400 provided in the embodiments of the present application can be any, for example, the driving member 400 can be an electric push rod, a linear motor, a gas cylinder, etc., or can be a rotating motor including a transmission structure.

[0090] The specific form of the driving member 400 is not limited in the embodiments of the present application.

[0091] It can be understood that the moving direction of the shielding member 300 needs to occupy a large space. In order to reduce the floor space occupied by the driving member 400, in the embodiments of the present application, the driving member 400 can be a rotating motor including a transmission structure, so as to reduce the size of the driving member 400.

[0092] It should be noted that the transmission structure can include but is not limited to elements such as gears and racks, and the number of elements can be selected according to actual conditions. In the embodiments of the present application, the transmission structure 400 can include a plurality of gears and a rack, and the plurality of gears are meshed with each other to change the position of the output shaft of the driving member 400, thereby optimizing the layout of the driving member 400 in the cleaning device 10.

[0093] The working process of the cleaning device 10 will be described below from different situations, i.e., a first situation and a second situation:

[0094] It can be understood that the first case refers to the state when the cleaning device 10 is in cleaning operation and the surface to be cleaned is a carpet, a rug, etc.; the second case includes but is not limited to any state that does not conform to the first case, such as the cleaning device 10 being in cleaning operation but the surface to be cleaned not being a carpet, a rug, etc., the cleaning device 10 being in charging state, the cleaning device 10 being in water supply and drainage state, etc. The first case and the second case in the following content are the same, and will not be repeated.

[0095] Referring to Figure 3 , Figure 5 It can be understood that when the cleaning device 10 is in the first case, the driving member 400 drives the shielding member 300 to move in the first direction X, so that the shielding member 300 is inserted between the cleaning member 200 and the surface to be cleaned, and the shielding member 300 can cover the contact part 210 to block the cleaning member 200 from contacting the dirt, thereby preventing the water stains, dirt, etc. on the cleaning member 200 from staining the object.

[0096] Referring to Figure 4 , Figure 6 When the cleaning device 10 is in the second case, the driving member 400 drives the shielding member 300 to move reversely in the first direction X, thereby removing the shielding of the cleaning member 200, so that the cleaning member 200 can normally contact the surface to be cleaned to perform cleaning operation.

[0097] Through the above arrangement, the shielding member 300 can effectively avoid the cleaning device 10 from causing pollution to the object which is not expected to be wet during cleaning, thereby improving the cleaning effect and user experience of the cleaning device 10, and also can flexibly switch the shielding and cleaning states according to different cleaning requirements, thereby improving the applicability and working efficiency of the cleaning device 10.

[0098] Referring to Figure 3 , Figure 5 Among them, the shielding member 300 is arranged between the cleaning member 200 and the surface to be cleaned in the second direction Y, so that the shielding member 300 can form effective isolation, and the cleaning member 200 cannot directly contact the carpet, the rug, etc. surface to be cleaned during cleaning, thereby effectively avoiding pollution of the carpet, the rug, etc. surface to be cleaned by dirt.

[0099] In addition, by arranging the first direction X and the second direction Y to intersect, the shielding member 300 can effectively shield the cleaning member 200, thereby isolating the cleaning member 200 and the surface to be cleaned.

[0100] It can be understood that the first direction X refers to the traveling direction of the cleaning device 10, and the intersection angle between the second direction Y and the first direction X can be any angle, for example, the intersection angle between the second direction Y and the first direction X can be 30°, 45°, 60°, 90°, 120°, etc. The present application does not limit the above-mentioned intersection angle and is not limited to the above-mentioned examples. The intersection angle between the second direction Y and the first direction X is 90° as an example.

[0101] The first direction X is taken as the horizontal direction as an example below, and the second direction Y is the vertical direction.

[0102] Referring to Figure 3 , Figure 5 As an optional embodiment, in the second direction Y, the orthogonal projection of the shielding piece 300 on the surface to be cleaned covers at least the orthogonal projection of the cleaning piece 200 on the surface to be cleaned.

[0103] It can be understood that if the orthogonal projection of the shielding piece 300 on the surface to be cleaned is smaller than the orthogonal projection of the cleaning piece 200, that is, part of the cleaning piece 200 is exposed outside the shielding piece 300, part of the cleaning piece 200 is easy to contact the surface to be cleaned, and water stains, dirt, etc. on the cleaning piece 200 can be easily stained on the surface to be cleaned which is not desired to be wet, and effective shielding and protection cannot be achieved.

[0104] Therefore, when the orthogonal projection of the shielding piece 300 covers at least the orthogonal projection of the cleaning piece 200, the shielding piece 300 can block the contact between the cleaning piece 200 and the surface to be cleaned, and ensure that water stains, dirt, etc. on the cleaning piece 200 cannot be stained on the surface to be cleaned which is not desired to be wet, which can effectively solve the problems in the prior art, and further improve the cleaning effect and user experience of the cleaning device 10.

[0105] It should be noted that the shape and size of the shielding piece 300 are not limited in the present application, and the user can adjust them according to the actual situation.

[0106] Referring to Figure 5 , Figure 6 As an optional embodiment, the cleaning piece 200 includes a contact part 210 and a non-contact part 220 connected to each other. It can be understood that the contact part 210 contacts the surface to be cleaned and is used to perform cleaning operations such as adsorbing dust and stains, etc.; the non-contact part 220 does not contact the surface to be cleaned and is used to support, connect, and drive the contact part 210, etc. When the cleaning piece 200 is located on the surface to be cleaned, the contact part 210 is used to contact the surface to be cleaned.

[0107] It should be noted that the contact part 210 can adopt different cleaning methods and forces according to different to-be-cleaned surface materials and stain types, so as to improve the cleaning efficiency and quality. In addition, since the non-contact part 220 does not contact the to-be-cleaned surface, the cleaning effect can be affected due to wear or damage of the non-contact part 220, the service life of the cleaning piece 200 is prolonged, and the maintenance cost of the cleaning equipment 10 is reduced.

[0108] Further, according to the foregoing, when the type of the cleaning piece 200 is a roller, a track, etc., the cleaning piece 110 can rotate relative to the equipment main body 100, and therefore, the contact part 210 and the non-contact part 220 are both dynamically changed.

[0109] Referring to Figure 5 In the second direction Y, the orthogonal projection of the shielding piece 300 on the to-be-cleaned surface at least covers the orthogonal projection of the contact part 210 on the to-be-cleaned surface.

[0110] It can be understood that since the orthogonal projection of the shielding piece 300 at least covers the orthogonal projection of the contact part 210, the shielding piece 300 can form a barrier to isolate the cleaning piece 200 from carpets, blankets, etc. during the cleaning operation, so as to avoid that the water stains and dirt on the contact part 210 directly contact the carpets, blankets, etc., thereby protecting the cleanliness of the carpets, blankets, etc., improving the user's satisfaction with the cleaning equipment 10, and meeting the user's high-quality requirements for cleaning different material articles.

[0111] Referring to Figures 3-9 As an optional embodiment, the shielding piece 300 includes a first support rod 310 and a flexible shielding part 320, and the first support rod 310 is fixedly connected to the output end of the driving piece 400.

[0112] It can be understood that the first support rod 310 can play a supporting and connecting role, provides a mounting and fixing basis for the flexible shielding part 320, and is connected to the output end of the driving piece 400 to transmit the power of the driving piece 400 to the flexible shielding part 320.

[0113] It can be understood that the fixed end of the flexible shielding part 320 is connected to the first support rod 310, and the movable end of the flexible shielding part 320 is wound on the first support rod 310. In the attached Figures 3-9 , the left end of the flexible shielding part 320 is the fixed end, and the right side is the movable end.

[0114] It can be understood that, for ease of understanding, referring to Figures 3-8 , the left side and the right side are two opposite directions of the first direction X, and the specific left side and right side will not be described below.

[0115] The flexible shielding part 320 can be kept stable during the unfolding and retracting process by being wound. The winding design can reduce the wear and damage of the flexible shielding part 320 during the unfolding and retracting process, and prolong the service life.

[0116] The driving member 400 is used to drive the first supporting rod 310 to rotate and drive the flexible shielding part 320 to unfold, so as to drive the movable end of the flexible shielding part 320 to move along the first direction X.

[0117] It can be understood that the cleaning device 10 drives the flexible shielding part 320 to unfold by driving the first supporting rod 310 to rotate, so as to fully utilize the flexibility and deformability of the flexible shielding part 320, so that the flexible shielding part 320 can adapt to different space and position requirements during the unfolding process, and realize accurate shielding of the cleaning member 200.

[0118] It should be noted that the flexible shielding part 320 refers to having flexibility to realize winding of the flexible shielding part 320.

[0119] It can be understood that the material of the flexible shielding part 320 can be selected from materials having certain flexibility and certain waterproof performance, such as silica gel, PET (Polyethylene terephthalate), soft glue, rubber, etc.

[0120] In addition, the movable end of the flexible shielding part 320 moves along the first direction X to ensure that the shielding member 300 can be accurately located between the cleaning member 200 and the surface to be cleaned after being unfolded, effectively preventing water stains, dirt, etc. on the cleaning member 200 from being attached to carpets, blankets and other objects that are not expected to be wet, thereby improving the cleaning effect and user experience of the cleaning device 10. In addition, this driving mode can also reduce manual intervention, improve the automation degree and working efficiency of the cleaning device 10, and reduce the labor intensity of the operator.

[0121] It can be understood that in the attached Figures 3-9 , the left end of the flexible shielding part 320 is the fixed end, and the right side is the movable end.

[0122] It should be noted that according to the Figures 3-9 direction shown in the figure, the winding can be clockwise winding with the first supporting rod 310 as the axis, or counterclockwise winding with the first supporting rod 310 as the axis. The winding process of the embodiment of the application is as follows: unfolding in the counterclockwise direction and retracting in the clockwise direction.

[0123] The specific use process is as follows:

[0124] Referring to Figure 3 , Figure 5When the cleaning device 10 is in the first state, the driving member 400 can drive the first supporting rod 310 to rotate, the flexible shielding part 320 wound on the first supporting rod 310 starts to release, the movable end of the flexible shielding part 320 moves along the first direction X until the shielding member 300 is located between the cleaning member 200 and the surface to be cleaned along the second direction Y, the shielding member 300 can cover the contact part 210, the driving member 400 stops moving, and the shielding member 300 can shield the cleaning member 200;

[0125] With reference to Figure 4 , Figure 6 When the cleaning device 10 is in the second state, the driving member 400 can drive the first supporting rod 310 to rotate reversely to drive the flexible shielding part 320 to be wound on the first supporting rod 310, and then the movable end of the flexible shielding part 320 moves reversely along the first direction X until the original position is restored, the driving member 400 stops moving, and the shielding member 300 does not shield the cleaning member 200, so that the cleaning member 200 can be used to clean the surface to be cleaned.

[0126] With reference to Figures 3-9 As an optional embodiment, the cleaning device 10 further comprises a guiding member 500 extending along the first direction X. The guiding member 500 is used to guide the expansion and retraction of the flexible shielding part 320. It can be understood that the guiding member 500 is generally in a strip shape, which is used to guide and limit the movement of other components, and ensure that the movable end of the flexible shielding part 320 moves along a predetermined direction.

[0127] It should be noted that, in order to ensure the guiding effect of the guiding member 500, the guiding member 500 can extend along the first direction X.

[0128] The specific structure of the guiding member 500 will be described below.

[0129] With reference to the accompanying Figure 3 - the accompanying Figure 9 Specifically, the guiding member 500 comprises a rack 510, a track 520, a first gear 530, a second gear 540, a fixed rod 550, a third gear 560 and an auxiliary rod 570.

[0130] As an optional embodiment, the side of the guiding member 500 facing the cleaning member 200 is connected with the movable end of the flexible shielding part 320, and the side of the guiding member 500 away from the cleaning member 200 is connected with the output end of the driving member 400.

[0131] Specifically, the rack 510 is slidingly arranged on the track 520. The track 520 is connected with the fixed end of the driving member 400, that is, the position of the track 520 is relatively fixed with the driving member 400, that is, when the rack 510 slides, the positions of the track 520 and the fixed end of the driving member 400 are unchanged.

[0132] The side of the rack 510 facing away from the cleaning member 200 is in transmission connection with the output end of the driving member 400, and the first gear 530 is in meshing connection with the rack 510, and the first gear 530 is connected with the output end of the driving member 400.

[0133] In this way, the rotary motion of the driving member 400 can be converted into the linear motion of the rack 510, so as to drive the flexible shielding part 320 to move along the preset first direction X. The track 520 provides stable support for the rack 510, ensuring the position accuracy and stability of the rack 510 during the movement, avoiding transmission errors or shielding failures caused by the shaking or deviation of the rack 510.

[0134] In addition, the movement of the flexible shielding part 320 is synchronized with the movement of the rack 510, and the movable end of the flexible shielding part 320 will move synchronously with the movement of the rack 510, thereby realizing the shielding or unshielding function of the cleaning member 200.

[0135] Secondly, the rotation of the driving member 400 can be converted into the linear motion of the rack 510 through the meshing of the first gear 530 and the rack 510, so as to drive the flexible shielding part 320 to move along the first direction X, realizing the unfolding and retracting of the shielding member 300. The transmission of the first gear 530 and the rack 510 has the advantages of high transmission accuracy, stable transmission ratio, large carrying capacity, etc., which can ensure the speed and position accuracy of the rack 510 during the movement, and improve the reliability and stability of the whole shielding system.

[0136] In this way, the output end of the driving member 400 can drive the first gear 530 to rotate, so as to drive the rack 510 to move on the track 520.

[0137] Further, the fixed rod 550 is connected with the movable end of the flexible shielding part 320, and is connected with the side of the rack 510 facing the cleaning member 200. In this way, the rack 510 can drive the fixed rod 550 to move, and in turn drive the movable end of the flexible shielding part 320 to move, and in turn unfold the flexible shielding part 320, so that the shielding member 300 can be located between the cleaning member 200 and the surface to be cleaned, and in turn realize the coverage of the contact part 210, thereby realizing the shielding of the cleaning member 200.

[0138] Through the above setting, the fixed rod 550 can effectively connect the movable end of the flexible shielding part 320 and the rack 510, and ensure the relative position and movement relationship between the two, thereby improving the stability and accuracy of the whole shielding system.

[0139] In addition, the fixed rod 550 can also play the role of support and guide, reducing the shaking and deviation of the flexible shielding part 320 and the rack 510 during the movement, and further improving the performance and service life of the cleaning equipment 10.

[0140] It can be understood that, with reference to Figure 3 、 Figure 5 When the cleaning device 10 is in the first state, the driving member 400 can drive the first supporting rod 310 to rotate, synchronously drive the rack 510 to move along the first direction X, and then drive the movable end of the flexible shielding part 320 to move along the first direction X through the fixed rod 550 until the shielding member 300 is located between the cleaning member 200 and the surface to be cleaned in the second direction Y, the shielding member 300 can cover the contact part 210, the driving member 400 stops moving, and the shielding member 300 can shield the cleaning member 200.

[0141] With reference to Figure 4 、 Figure 6 When the cleaning device 10 is in the second state, the driving member 400 can drive the first supporting rod 310 to rotate reversely, synchronously drive the rack 510 to move reversely along the first direction X, drive the first supporting rod 310 to rotate, synchronously drive the rack 510 to move along the first direction X, drive the movable end of the flexible shielding part 320 to move reversely along the first direction X through the fixed rod 550 until the original position is restored, the driving member 400 stops moving, and the shielding member 300 does not shield the cleaning member 200, so that the cleaning member 200 can be used to clean the surface to be cleaned.

[0142] The above design makes the guide member 500 not only have a guiding function, but also have a power transmission and motion conversion function, thereby improving the overall performance and working efficiency of the cleaning device 10.

[0143] It should be noted that, if the guide member 500 is not arranged, when the cleaning device 10 travels on uneven ground, the movable end of the flexible shielding part 320 can shake due to the bumping of the ground, thereby affecting the shielding effect. In addition, if the guide member 500 is not connected between the output end of the driving member 400, the power of the driving member 400 cannot be effectively transmitted to the movable end of the flexible shielding part 320, thereby causing the shielding member 300 to be unable to normally expand and retract, and affecting the normal work of the cleaning device 10.

[0144] As an optional implementation, the second gear 540 is sleeved on the end of the first supporting rod 310 and is rotationally connected with the device main body 100. The first gear 530 and the second gear 540 are both connected with the output end of the driving member 400, and the two gears are both used for transmitting power but are respectively used for realizing different functions.

[0145] The second gear 540 is sleeved on the end of the first supporting rod 310 and is rotationally connected with the device main body 100, can limit and guide the rotation of the first supporting rod 310, and ensures the stability and accuracy of the first supporting rod 310 during rotation.

[0146] It can be understood that the number of the second gears 540 can be multiple, and the multiple second gears 410 are respectively located at opposite ends of the first support rod 310. The middle part of the first support rod 310 is a smooth surface, and the first support rod 310 can wind the flexible shielding part 320 through the smooth surface.

[0147] With reference to Figures 3-6 As an optional embodiment, the guide member 500 further comprises an auxiliary rod 570 and a third gear 560, the third gear 560 is sleeved on the auxiliary rod 570, the auxiliary rod 570 is spaced apart from the support rod, and the third gear 560 is engaged with the second gear 540.

[0148] Specifically, the auxiliary rod 570 can provide stable support for the third gear 560, so that the auxiliary rod 570 can be accurately engaged with the second gear 540 to realize power transmission and conversion. At the same time, the engagement of the third gear 560 and the second gear 540 can form a gear transmission system, which transmits the rotation of the second gear 540 to the third gear 560, thereby driving the movement of the auxiliary rod 570 and related components, realizing the rotation control of the first support rod 310, and improving the stability and reliability of the entire shielding system.

[0149] It can be understood that the auxiliary rod 570 is connected with the third gear 560 and connected with the output end of the driving member 400, so that when the driving member 400 rotates, the rack 510 moves synchronously, and the movable end of the flexible shielding part 320 moves.

[0150] By increasing the auxiliary rod 570 and the third gear 560, the rotation control of the first support rod 310 can be realized while the guiding and supporting of the rack 510 and the flexible shielding part 320 are realized, so as to meet the needs of the cleaning equipment 10 in different working scenes. For example, when the rotation of the first support rod 310 needs to be accurately controlled, the setting of the auxiliary rod 570 and the third gear 560 can provide stable power transmission and motion control, so as to ensure the accurate rotation of the first support rod 310, thereby improving the performance and reliability of the cleaning equipment 10.

[0151] It can be understood that the output end of the driving member 400 simultaneously drives multiple structures to operate together.

[0152] For example, the output end of the driving member 400 can be engaged with the rack 510 through the first gear 530, and the right end of the rack 510 is provided with a fixed rod 550 for connecting the movable end of the flexible shielding part 320.

[0153] Meanwhile, the output end of the driving member 400 can be connected with the third gear 560 through the auxiliary rod 570, the third gear 560 is engaged with the second gear 540, and the second gear 540 is connected to the end of the first support rod 310 for connecting the fixed end of the flexible shielding part 320.

[0154] When the cleaning device 10 is in the first state, the driving member 400 can drive the first support rod 310 to rotate to release the winding of the flexible shielding part 320; the synchronous belt drives the rack 510 to move in the first direction X, and then the fixed rod 550 drives the movable end of the flexible shielding part 320 to move in the first direction X, until the shielding member 300 is located between the cleaning member 200 and the surface to be cleaned in the second direction Y, the shielding member 300 can cover the contact part 210, the driving member 400 stops moving, and the shielding member 300 can shield the cleaning member 200;

[0155] When the cleaning device 10 is in the second state, the driving member 400 can drive the first support rod 310 to rotate in the reverse direction to tighten the winding of the flexible shielding part 320; the synchronous belt drives the rack 510 to move in the first direction X in the reverse direction, the driving member 400 can drive the first support rod 310 to rotate, the synchronous belt drives the rack 510 to move in the first direction X, the fixed rod 550 drives the movable end of the flexible shielding part 320 to move in the first direction X in the reverse direction, until the original position is restored, the driving member 400 stops moving, and the shielding member 300 does not shield the cleaning member 200, so that the cleaning member 200 can be used to clean the surface to be cleaned.

[0156] With reference to Figure 8 It can be understood that the shielding member 300 generally has a large area, in order to ensure the movement accuracy of the shielding member 300, the guide member 500 can include a plurality of racks 510, and the plurality of racks 510 can be distributed at intervals along the rotation axis of the driving member 400, so as to improve the movement stability of the flexible shielding part 320.

[0157] Through the above arrangement, the movable end of the flexible shielding part 320 can move linearly along the extension direction of the guide member 500, avoiding shaking or deviation during movement, ensuring that the shielding member 300 can accurately form an effective shielding between the cleaning member 200 and the surface to be cleaned, preventing water stains, dirt and the like on the cleaning member 200 from being stained on the carpet or blanket that is not expected to be wet, and improving the cleaning effect and user experience of the cleaning device 10.

[0158] With reference to Figure 3 , Figure 4As an optional implementation, the cleaning device 10 further comprises a limiting member 600, which is located on the side of the first supporting rod 310 away from the guide member 500, and has a limiting cavity in which the first supporting rod 310 is rotatably arranged. The limiting member 600 is used to limit and guide the movement of the first supporting rod 310, so as to ensure the stability and accuracy of the first supporting rod 310 during rotation.

[0159] It can be understood that the limiting member 600 can effectively limit the movement range and direction of the first supporting rod 310, prevent the first supporting rod 310 from deviating or shaking excessively during rotation, and thus improve the stability and reliability of the cleaning device 10.

[0160] Through the above arrangement, the limiting member 600 and the guide member 500 can constrain and support the first supporting rod 310 from different directions to form a stable structure. The limiting member 600 is located on the side of the first supporting rod 310 away from the guide member 500, which can effectively prevent the first supporting rod 310 from deviating or shaking to this side during rotation, thereby improving the rotation accuracy and stability of the first supporting rod 310.

[0161] The limiting cavity can limit and guide the rotation of the first supporting rod 310, ensure the accuracy of the rotation direction and position of the first supporting rod 310, and improve the stability and reliability of the cleaning device 10. At the same time, the rotation of the first supporting rod 310 in the limiting cavity can also reduce friction and resistance during rotation, prolong the service life of the device.

[0162] It can be understood that if the limiting cavity is not arranged, the first supporting rod 310 may deviate or shake during rotation due to external force or its own inertia, which may cause collision or interference with other components and affect the normal work of the cleaning device 10.

[0163] In the embodiments of the present application, the limiting member 600 can at least have a first limiting plate 610 and a second limiting plate 620 arranged intersectingly, and the first limiting plate 610 and the second limiting plate 620 can be connected at the intersection to form an "L" shaped structure, and the flexible shielding part 320 wound on the first supporting rod 310 can be located in the "L" shaped structure. The limiting cavity is formed among the first limiting plate 610, the second limiting plate 620 and the guide member 500. The limiting cavity can be in communication with the external environment to keep the movable end and the fixed end of the flexible shielding part 320 connected.

[0164] Referring to Figures 1-6 As an optional implementation, in the first direction X, the shielding member 300 is located on one side of the cleaning member 200.

[0165] Exemplarily, the shielding piece 300 is arranged at one side of the cleaning piece 200, and the extension and retraction timing of the shielding piece 300 can be effectively controlled according to the traveling direction of the cleaning device 10, so as to ensure that the objects such as carpets and blankets that do not want to be wetted are shielded in time during the cleaning process, and the water stains, dirt and the like on the cleaning piece 200 are prevented from being stained on the objects, thereby improving the cleaning effect and user experience.

[0166] With reference to the accompanying drawings Figure 1 , Figure 2 , Figure 4 , Figures 6-9 It can be known that the shielding piece 300 is arranged at the left side of the cleaning piece 200. In addition, when the cleaning device 10 is in the first case, the shielding piece 300 can be extended from one side of the cleaning piece 200 and isolated from the objects, so as to prevent the water stains, dirt and the like on the cleaning piece 200 from being stained on the cleaning surface. Meanwhile, the shielding piece 300 is arranged at one side of the cleaning piece 200, which is also beneficial to simplify the structure and movement mode of the shielding piece 300, reduce the interference between the shielding piece 300 and the cleaning piece 200, and improve the overall stability and reliability of the cleaning device 10. In addition, the above position arrangement can also make the cleaning device 10 more flexible during the cleaning process, better adapt to different cleaning scenes and working states, and improve the cleaning effect and user experience.

[0167] As another optional implementation, the number of shielding pieces 300 is multiple, and the multiple shielding pieces 300 are respectively arranged at different sides of the cleaning piece 200, and the multiple shielding pieces 300 all move towards the cleaning piece 200.

[0168] During the cleaning process, each shielding piece 300 is arranged at different positions of the cleaning piece 200, such as the left side, the right side, the front side and the back side, so as to ensure that the cleaning piece 200 is shielded from all directions. The multiple shielding pieces 300 can shield the cleaning piece 200 from different directions and positions, so as to ensure that the cleaning piece 200 cannot contact the objects such as carpets and blankets that do not want to be wetted in all directions, and effectively prevent the water stains, dirt and the like on the cleaning piece 200 from being stained on the objects. In addition, the multiple shielding pieces 300 can also be flexibly configured and adjusted according to actual cleaning requirements, improve the adaptability and universality of the cleaning device 10, and meet the requirements in different cleaning scenes.

[0169] It should be noted that when the number of shielding pieces 300 is multiple, the multiple shielding pieces 300 can be spliced with each other, and the shielding pieces 300 at different positions can be expanded and retracted in different directions.

[0170] The specific number of the shielding piece 300 is not limited in the embodiments of the present application, and is not limited to the above examples.

[0171] In addition, the plurality of shielding members 300 can also be in different orientations of the cleaning member 200, such as left side, right side, front side, back side, etc., to ensure that the shielding member 300 can shield the cleaning member 200 from all directions.

[0172] As an optional implementation, the cleaning device 10 further comprises a controller (not shown in the figure) and an identifier (not shown in the figure), the identifier is located on the cleaning device 10, the controller is located on one of the cleaning device 10 and the base station, the controller is electrically connected with the identifier, and the identifier is used to identify the to-be-cleaned surface and generate to-be-cleaned surface information.

[0173] Through the identification function of the identifier, the cleaning device 10 can obtain information such as the material and type of the to-be-cleaned surface, providing a basis for subsequent cleaning operations. For example, the identifier can identify whether the to-be-cleaned surface is a carpet, a blanket, or a normal ground, and convert these information into electrical signals or other forms of signals and transmit them to the controller.

[0174] The controller is configured to obtain the to-be-cleaned surface information provided by the identifier, and determine the position of the shielding member 300 according to the to-be-cleaned surface information. After receiving the to-be-cleaned surface information from the identifier, the controller analyzes and processes the information through a preset program and algorithm, determines the material and type of the current to-be-cleaned surface, and further determines the position of the shielding member 300.

[0175] If the to-be-cleaned surface is a carpet or a blanket, the controller will determine that the shielding member 300 needs to be located between the cleaning member 200 and the to-be-cleaned surface to prevent water stains and dirt on the cleaning member 200 from staining the carpet or blanket;

[0176] If the to-be-cleaned surface is a normal ground, the controller will determine that the shielding member 300 does not need to be located between the cleaning member 200 and the to-be-cleaned surface, so that the cleaning device 10 can normally perform the cleaning operation.

[0177] Through the cooperation of the identifier and the controller, the cleaning device 10 can automatically identify the material and type of the to-be-cleaned surface, and automatically adjust the position of the shielding member 300 according to the identification result, realizing the automation and intelligentization of the cleaning operation, and reducing the complexity and labor intensity of manual operation. Secondly, the above-mentioned automatic adjustment function can effectively protect the to-be-cleaned surface of special materials such as carpets and blankets, avoid pollution caused by water stains and dirt of the cleaning device 10, and improve the cleaning effect and user satisfaction of the cleaning device 10. In addition, the above design can improve the adaptability and universality of the cleaning device 10, so that it can better cope with to-be-cleaned surfaces of different materials and types, and meet the cleaning needs of users in different scenarios.

[0178] As an optional implementation, when the to-be-cleaned surface information includes a preset type, the controller controls the rotation of the driving member 400 to drive the shielding member 300 to move until the shielding member 300 is located between the cleaning member 200 and the to-be-cleaned surface.

[0179] It can be understood that the above design enables the cleaning device 10 to automatically drive the driving member 400 to rotate when the to-be-cleaned surface type requiring special treatment is identified, thereby driving the shielding member 300 to move, so as to ensure that the shielding member 300 can effectively block the direct contact between the cleaning member 200 and the to-be-cleaned surface when the to-be-cleaned surface of a special material is cleaned, and prevent water stains, dirt and the like on the cleaning member 200 from being attached to the carpet, the blanket and the like of the special material, thereby effectively protecting the cleanliness of these materials and improving the cleaning effect and user satisfaction of the cleaning device 10.

[0180] Meanwhile, the automatic detection and adjustment function described above can reduce the complexity of manual operation, thereby improving the automation degree and intelligent level of the cleaning device 10.
