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

[0002] At present, people have an increasing demand for smart home appliances. For whole-house cleaning, cleaning robots are a widely used cleaning device. With the help of artificial intelligence, cleaning robots can automatically complete floor cleaning in the room. Moreover, cleaning robots are generally used in conjunction with a cleaning base station that is compatible with them. The cleaning base station can be used to clean and charge the cleaning robot.

[0003] Generally, a cleaning robot has a casing, a reduction gearbox, a roller and two drive motors, the reduction gearbox and the two drive motors are all connected to the casing, and one of the two drive motors and the roller are both connected to the reduction gearbox, and the roller can be driven to rotate through the reduction gearbox under the drive of the drive motor, so that the roller cleans the floor; because the cleaning robot may encounter obstacles during use, it is necessary to separate the roller from the floor, that is, to lift the roller upwards, and after passing the obstacle, it is necessary to lower the roller to continue cleaning the floor, therefore, the other of the two drive motors can drive the roller to rise and fall through a linkage structure such as a gear rack.

[0004] However, in the above-mentioned cleaning robot, the structure for driving the roller to rotate and the structure for driving the roller to lift and lower occupy a large space inside the cleaning robot and make the internal structure of the cleaning robot more complicated, making it inconvenient to assemble the cleaning robot and resulting in low assembly efficiency of the cleaning robot. Summary of the invention

[0005] The embodiments of the present application provide a cleaning component, a cleaning device and a cleaning system, which can simplify the internal structure of a cleaning robot, thereby facilitating the assembly of the cleaning robot and increasing the assembly efficiency of the cleaning robot.

[0006] In the first aspect, the present application provides a cleaning assembly, including a fixed frame structure, a cleaning bracket, a cleaning member, a driving member, a rotating shaft and a cam member, wherein the fixed frame structure is used to be connected to a housing of the cleaning equipment; the cleaning bracket is located below the fixed frame structure and slides with the fixed frame structure in the up and down directions; the cleaning member is rotatably connected to the cleaning bracket; the driving member is arranged on the cleaning bracket, and the driving member is transmission-connected to the cleaning member, the driving member has a driving shaft, and when the driving shaft rotates along a first direction, the driving member drives the cleaning member to rotate so that the cleaning member cleans the floor; one end of the rotating shaft is transmission-connected to the driving member, and the other end of the rotating shaft is rotationally connected to the cleaning bracket; the cam member is connected to the rotating shaft and can abut against the fixed frame structure, and when the driving shaft rotates along a second direction, the driving member drives the rotating shaft and the cam member to rotate synchronously so that the cleaning member rises or falls; wherein the first direction is opposite to the second direction.

[0007] In some embodiments, the cam member includes a main body and a cam, the main body has an axial hole for the rotating shaft to pass through, and the main body is connected to the rotating shaft; the cam has a proximal rest end and a distal rest end, when the proximal rest end abuts against the fixed frame structure, the cleaning member is in a lowered position; when the distal rest end abuts against the fixed frame structure, the cleaning member is in an ascending position.

[0008] In some embodiments, two detection modules are arranged on the cleaning bracket, and two trigger parts are arranged on the main body, and one trigger part corresponds to one detection module; when the near end abuts against the fixed frame structure, one of the two trigger parts triggers one of the two detection modules, so that the detection module outputs a signal that the cleaning member is in a lowered position; when the far end abuts against the fixed frame structure, the other of the two trigger parts triggers the other of the two detection modules, so that the detection module outputs a signal that the cleaning member is in an ascending position. In this way, the detection module can effectively control the start and stop of the driving member, and the operation is convenient and the degree of automation is high.

[0009] In some embodiments, a accommodating space for accommodating the cam member is formed on one side of the fixing frame structure facing the cleaning bracket, and a groove extending downward is formed at the bottom of the accommodating space, and the proximal end or the distal end can abut against the bottom wall of the groove. In this way, the cam can cooperate with the groove, so that the cleaning member can be in the ascending position or the descending position.

[0010] In some embodiments, the fixing frame structure includes a first fixing frame and a second fixing frame; the first fixing frame is used to connect to the housing, the second fixing frame is connected below the first fixing frame, and a containing space is formed between the first fixing frame and the second fixing frame.

[0011] In some embodiments, the number of cams is at least two, and at least two cams are arranged at intervals along the length direction of the main body, wherein at least two cams are located on opposite sides of the center of the cleaning bracket in the length direction of the cleaning bracket. In this way, the stability of the cam member during the rotation process can be improved, so that the cleaning member has higher stability during the lifting process.

[0012] In some embodiments, the cleaning assembly provided by the present application further includes a balancing member, the two ends of which are rotatably connected to the cleaning bracket, and the two ends of the balancing member are respectively located on opposite sides of the center of the cleaning bracket; at least a portion of the structure of the balancing member located between the two ends is pressed against the fixed frame structure, and the balancing member is used to drive the two ends of the cleaning bracket along its length direction to be in the same horizontal plane during the lifting and lowering process of the cleaning bracket. In this way, by setting the balancing member, the situation of inconsistent heights of the two ends of the cleaning member along its axial direction can be avoided to a certain extent during the lifting and lowering process of the cleaning member.

[0013] In some embodiments, the cam is located between the two ends of the balancing member in the length direction of the cleaning bracket, so that the stability of the cleaning member during the lifting process can be further improved.

In this way, by setting a concave cavity on the second fixing frame, the position of the balancing member can be restricted when the cleaning member cleans the floor, so as to avoid the middle part of the balancing member being suspended in the air, which affects the normal use of the cleaning device.

[0016] In some embodiments, the cleaning assembly provided by the present application further includes an elastic member; the elastic member is disposed between the fixed frame structure and the cleaning bracket, and the elastic member is used to apply pressure to the cleaning bracket away from the fixed frame structure; or the elastic member is disposed between the fixed frame structure and the cam member, and the elastic member is used to apply pressure to the cam member away from the fixed frame structure. In this way, pressure can be applied to the cleaning member, so that the cleaning member is effectively attached to the ground, thereby improving the cleaning effect of the cleaning member.

[0017] In some embodiments, a one-way bearing is sleeved on the outer side of one end of the rotating shaft that is transmission-connected to the driving member, so that the rotating shaft can be stopped when the driving shaft rotates in the first direction.

[0018] In some embodiments, a guide sleeve is provided on the side of the fixed frame structure facing the cleaning bracket, and a guide column is provided on the side of the cleaning bracket facing the fixed frame structure; the guide column extends into the guide sleeve, and the guide column and the guide sleeve slide in the up and down direction.

[0068] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0069] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0070] In the description of the present application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0071] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0072] The cleaning system includes cleaning equipment and a cleaning base station. The cleaning equipment can be used to clean dirty areas of the environment such as the ground, sofa surface, and seat surface, and remove foreign objects such as dust and peels from the dirty areas; specifically, the cleaning equipment can suck and store foreign objects from the dirty areas so as to centrally process the garbage. The cleaning equipment can be a vacuum cleaner, a floor scrubber, a cleaning robot, etc., without limitation. The cleaning base station can be used in conjunction with the cleaning equipment; specifically, the cleaning base station can be used to charge the cleaning equipment, add cleaning fluid, suck out garbage stored in the cleaning equipment, etc., without limitation.

[0073] Generally, a cleaning robot has a housing, a reduction box, a roller and two drive motors. The reduction box and the two drive motors are connected to the housing, and one of the two drive motors and the roller are connected to the reduction box. Under the drive of the drive motor, the roller can be driven to rotate through the reduction box so that the roller cleans the floor. Since the cleaning robot may encounter obstacles during use, it is necessary to separate the roller from the floor, that is, to lift the roller upwards. After passing the obstacle, the roller needs to be lowered to continue cleaning the floor. Therefore, the other of the two drive motors can drive the roller to rise and fall through a linkage structure such as a gear rack. However, in the above-mentioned cleaning robot, the structure for driving the roller to rotate and the structure for driving the roller to rise and fall occupy a large space inside the cleaning robot, and make the internal structure of the cleaning robot more complicated, which is not convenient for assembling the cleaning robot, resulting in low assembly efficiency of the cleaning robot.

[0074] Therefore, the present embodiment provides a cleaning component, a cleaning device and a cleaning system, which can simplify the internal structure of the cleaning robot, thereby facilitating the assembly of the cleaning robot and increasing the assembly efficiency of the cleaning robot.

[0075] It should be noted that the cleaning equipment provided in this embodiment includes but is not limited to a cleaning robot.

[0076] The embodiments of the present application will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0077] See also Figures 1 to 4 , Figure 1 This is a schematic diagram of the three-dimensional structure of the cleaning assembly provided in an embodiment of the present application when the cleaning member is in an ascending state. Figure 2 for Figure 1 A schematic diagram of the local structure of the structure in Figure 3 This is a schematic diagram of the three-dimensional structure of the cleaning assembly provided in an embodiment of the present application when the cleaning member is in a lowered state. Figure 4 for Figure 3 Exploded diagram of Figures 1 to 4As shown, the present embodiment provides a cleaning assembly 10, including a fixed frame structure 1, a cleaning bracket 2, a cleaning member 3, a driving member 4, a rotating shaft 5 and a cam member 6, wherein the fixed frame structure 1 is used to be connected to the housing of the cleaning device, for example, the fixed frame structure 1 is connected to the upper shell of the housing; the cleaning bracket 2 is located below the fixed frame structure 1 and slides with the fixed frame structure 1 in the up and down directions; the cleaning member 3 is rotatably connected to the cleaning bracket 2; the driving member 4 is arranged on the cleaning bracket 2, and the driving member 4 is transmission-connected with the cleaning member 3, the driving member 4 has a driving shaft, and when the driving shaft rotates in a first direction, the driving member 4 drives the cleaning member 3 to rotate, so that the cleaning member 3 cleans the floor, it should be noted that the driving member 4 here can be a driving motor; one end of the rotating shaft 5 is transmission-connected with the driving member 4, and the other end of the rotating shaft 5 is rotationally connected with the cleaning bracket 2; the cam member 6 is connected to the rotating shaft 5 and can abut against the fixed frame structure 1, and when the driving shaft rotates in a second direction, the driving member 4 drives the rotating shaft 5 and the cam member 6 to rotate synchronously, so that the cleaning member 3 rises or falls; wherein the first direction is opposite to the second direction. The cleaning component 10 provided in the present embodiment can realize the rotation of the cleaning component 3 by only setting a driving component 4, so that the cleaning component 3 cleans the ground, and can also realize the lifting and lowering of the cleaning component 3, so that the cleaning device can smoothly pass through obstacles during the movement. Therefore, compared with the related technology in which the structure for driving the cleaning component to rotate and the structure for driving the cleaning component to lift are different, the cleaning component provided in the present embodiment occupies less space, can reduce the structural complexity inside the cleaning device, facilitate the assembly of the cleaning device, and improve the assembly efficiency of the cleaning device.

[0078] In some specific implementations, when the cleaning member 3 rises or falls, the cleaning member 3 may or may not rotate; and in this embodiment, when the cleaning member 3 rises or falls, the cleaning member 3 rotates.

[0079] The first direction may be forward or reverse, when the first direction is forward, the second direction is reverse; when the first direction is reverse, the second direction is forward. It can be understood that when the driving shaft rotates forward, the cleaning member 3 also rotates forward, that is, the linear velocity of the contact point between the cleaning member 3 and the ground is opposite to the direction of movement of the cleaning device, and the reverse direction is the opposite direction to the forward direction.

[0080] It should be noted that the cleaning member 3 mentioned above can be a roller, a mop or a brush, etc. Here, there is no specific limitation on the implementation form of the cleaning member 3.

[0081] In order to realize that when the driving shaft rotates in the first direction, the rotating shaft 5 does not rotate, a one-way bearing 40 is sleeved on the outer side of one end of the rotating shaft 5 that is transmission-connected with the driving member 4. In this way, when the driving shaft rotates in the first direction, the cleaning member 3 rotates, the rotating shaft 5 does not rotate, and the cleaning member 3 does not rise or fall; when the driving shaft rotates in the second direction, the cleaning member 3 rotates, the rotating shaft 5 rotates, and the cleaning member 3 rises or falls while rotating.

[0082] The one-way bearing 40 is a kind of bearing that can rotate freely in one direction and is locked in the other direction. Here, "one direction" can be understood as the second direction in this embodiment, and "the other direction" can be understood as the first direction in this embodiment. Specifically, the metal shell of the one-way bearing 40 has a lot of rollers, needles or balls, and the shape of its rolling seat makes it roll only in one direction, while it will generate great resistance in the other direction. Here, the one-way bearing 40 is not introduced in detail.

[0083] Please continue to see Figures 5 to 8 , Figure 5 This is a schematic diagram of the three-dimensional structure of the fixing frame structure in the cleaning assembly provided in an embodiment of the present application. Figure 6 for Figure 5 Schematic diagram of the plane structure along direction A, Figure 7 for Figure 6 Cross-sectional view along BB direction, Figure 8 for Figure 7 The enlarged schematic diagram of the local structure at C in the middle. Figures 5 to 8 As shown, in some optional embodiments, the fixing frame structure 1 includes a first fixing frame 11 and a second fixing frame 12, the first fixing frame 11 is used to be connected to the housing, the second fixing frame 12 is connected to the bottom of the first fixing frame 11, and a receiving space 13 for accommodating the cam member 6 is formed between the first fixing frame 11 and the second fixing frame 12, the cam member 6 can abut against the side of the second fixing frame 12 facing the first fixing frame 11, and the rotating shaft 5 passes through the second fixing frame 12 and rotates with the cleaning bracket 2.

[0084] In order to facilitate the arrangement of the rotating shaft 5 and the cam member 6, in some embodiments, the first fixing frame 11 and the second fixing frame 12 may be connected in a detachable manner, for example Figure 7 and Figure 8 In the embodiment, a first connection hole 111 may be formed on the first fixing frame 11, and a second connection hole 121 corresponding to the first connection hole 111 may be formed on the second fixing frame 12, wherein the second connection hole 121 may be a countersunk hole, and the first fixing frame 11 and the second fixing frame 12 may be connected together by a fastener that is sequentially inserted into the second connection hole 121 and the first connection hole 111. The fastener may be a threaded fastener such as a screw, and the type of the fastener is not specifically limited.

[0085] In some other implementations, the first fixing frame 11 and the second fixing frame 12 may also be connected by snap fastenings. Here, the connection method between the first fixing frame 11 and the second fixing frame 12 is not specifically limited.

[0086] In order to improve the connection reliability between the first fixing frame 11 and the second fixing frame 12, a plurality of first connection holes 111 and a plurality of second connection holes 121 can be set, and one second connection hole 121 corresponds to one first connection hole 111. For example, there are four first connection holes 111 disposed at four corners, and four second connection holes 121 disposed at four corners. The two first connection holes 111 located on the same side are symmetrically disposed, and the two second connection holes 121 located on the same side are symmetrically disposed.

[0087] Please continue to see Fig. 9 , Fig. 9 This is a schematic diagram of the three-dimensional structure of the cleaning bracket in the cleaning assembly provided in the embodiment of the present application. Fig. 9 As shown, in some embodiments, the cleaning bracket 2 includes a bracket body 21, and in order to realize the rotational connection between the cleaning member 3 and the cleaning bracket 2, a rotating chamber 211 for accommodating the cleaning member 3 can be formed at the bottom of the bracket body 21, and the rotating chamber 211 is rotatably matched with the cleaning member 3 at both ends along the axial direction of the cleaning member 3, and the rotating chamber 211 is open at both ends along the front and rear directions of the cleaning device, and the driving member 4 is arranged at the top of the bracket body 21.

[0088] Please continue to see Figures 10 to 12 , Fig.10 This is a schematic diagram of the three-dimensional structure of a cam member in a cleaning assembly provided in an embodiment of the present application. Fig.11 for Figure 2 The enlarged schematic diagram of the local structure at D in the middle. Fig.12 for Figure 4 A schematic diagram of the partial structure at E in the middle is enlarged. In some embodiments, the cam member 6 includes a main body 61 and a cam 62, the main body 61 has an axial hole 611 for the rotating shaft 5 to pass through, and the main body 61 is connected to the rotating shaft 5. Specifically, a third connecting hole 623 connected to the axial hole 611 is formed on the main body 61, and a pin or a pin can pass through the third connecting hole 623 and the rotating shaft 5 to connect the cam 62 and the rotating shaft 5 together, wherein the third connecting hole 623 is formed on the cam 62; and in order to enable the cam member 6 to achieve the rise or fall of the cleaning member 3 during the rotation process, in this embodiment, the cam 62 has a near rest end 621 and a far rest end 622, when the near rest end 621 abuts against the second fixing frame 12, the cleaning member 3 is in a descending position, that is, the cleaning member 3 is in a position farthest from the ground; when the far rest end 622 abuts against the second fixing frame 12, the cleaning member 3 is in an ascending position, that is, the cleaning member 3 is in contact with the ground.

[0089] The proximal end is the smallest diameter of the cam 62 when it contacts the second fixing frame 12 ; the distal end 622 is the largest diameter of the cam 62 when it contacts the second fixing frame 12 .

[0090] In order to improve the stability of the cam member 6 during the rotation process, and further improve the stability of the cleaning member 3 during the lifting process, in some embodiments, there are at least two cams 62, and at least two cams 62 are arranged at intervals along the length direction of the main body 61; wherein, there are at least two cams 62 along the length direction of the cleaning bracket 2, respectively located on opposite sides of the center of the cleaning bracket 2. In this way, the stability of the cam member 6 during the rotation process can be improved, so that the cleaning member 3 has a higher stability during the lifting process.

[0091] In some specific embodiments, the cam 62 may be two, and the two cams 62 are symmetrically arranged about the central axis of the cleaning bracket 2. In this way, the cam member 6 occupies a small space and can be relatively stable during the rotation process. The following will take the arrangement of two cams 62 on the main body 61 as an example for further description.

[0092] In order to improve the connection reliability between the cam 62 and the rotating shaft 5, in some optional embodiments, a third connection hole 623 is formed on both cams 62, so that the synchronous rotation of the rotating shaft 5 and the cam member 6 is higher.

[0093] Please continue to see Figures 13 to 17 , Fig.13 This is a schematic diagram of the three-dimensional structure of the second fixing frame in the cleaning assembly provided in an embodiment of the present application. Fig.14 for Fig.13 A schematic diagram of the structure in another perspective. Fig.15 for Fig.13 A schematic diagram of the structure in another perspective. Fig.16 A schematic diagram of the matching relationship between the cam member and the second fixing frame when the cleaning member in the cleaning assembly provided in the embodiment of the present application is in an ascending state, Fig.17Schematic diagram of the matching relationship between the cam member and the second fixing frame when the cleaning member in the cleaning assembly provided in the embodiment of the present application is in a descending state. In order to make the proximal end 621 or the distal end 622 abut against the second fixing frame 12, in some optional embodiments, the second fixing frame 12 includes a main body 122 and abutting portions 123 connected to the main body 122 on both sides of the axial direction of the cleaning member 3, two spaced connecting lugs 124 can be provided on the rear side of the main body 122, each connecting lug 124 can be formed with a second connecting hole 121, and the front side of the main body 122 can be formed with an extension plate 125 extending forward, and the upper edge of the extension plate 125 The cleaning member 3 is provided with two second connection holes 121 spaced apart in the axial direction, and the second connection holes 121 on the extension plate 125 correspond to the second connection holes 121 on the two lugs 124 one by one. In order to enable both cams 62 to abut against the second fixing frame 12, in some optional embodiments, a groove 1231 extending downward may be formed on the abutting portion 123, and the near end 621 or the far end 622 may abut against the bottom wall of the groove 1231, so that the cleaning member 3 can be in the descending position or the ascending position. In this way, each cam 62 can cooperate with the corresponding groove 1231, so that the cleaning member 3 can be in the ascending position or the descending position.

[0094] It should be noted that when the cleaning member 3 is at the highest position, the cleaning member 3 needs to stop rotating, that is, the driving member 4 in this embodiment needs to stop working. When the cleaning device successfully passes through the obstacle, the driving member 4 needs to be restarted to make the cleaning member 3 drop to the lowest position and then clean the floor. Fig.18 and Fig.19 , Fig.18 for Figure 1 A schematic diagram of another partial structure of the structure in FIG. Fig.19 for Fig.18 An enlarged schematic diagram of the local structure at F in the middle. In some embodiments, two detection modules are provided on the side of the bracket body 21 facing the cam member 6, and two triggering parts 612 are provided on the main body 61, and one triggering part 612 corresponds to one detection module; when the near rest end 621 abuts against the bottom wall of the groove 1231, one of the two triggering parts 612 triggers one of the two detection modules, so that the detection module outputs a signal that the cleaning member 3 is in a descending position; when the far rest end 622 abuts against the bottom wall of the groove 1231, the other of the two triggering parts 612 triggers the other of the two detection modules, so that the detection module outputs a signal that the cleaning member 3 is in an ascending position. In this way, the detection module can effectively control the start and stop of the driving member 4, and the operation is convenient and the degree of automation is high.

[0095] It should be noted that the above detection module may include any one of a photoelectric switch 9, a reed switch proximity switch or a Hall proximity switch, wherein the photoelectric switch can utilize the blocking or reflection of the light beam by the detected object to connect the circuit by the synchronization circuit, thereby detecting the presence or absence of the object; and the reed switch proximity switch and the Hall proximity switch can both be used as position sensors. Here, no specific limitation is imposed on the above detection module. The following will take the detection module including the photoelectric switch 9 as an example for further introduction.

[0096] Specifically, a printed circuit board assembly (PCBA) 20 is provided on the side of the bracket body 21 facing the cam member 6, and two photoelectric switches 9 are provided on the printed circuit board 20; and in order to be able to trigger the photoelectric switch 9, in some optional embodiments, one trigger part 612 corresponds to one photoelectric switch 9, and a through hole 1221 for the two trigger parts 612 to pass through is formed at the bottom of the main body 122; when the proximal end 621 abuts against the bottom wall of the groove 1231, one of the two trigger parts 612 passes through the through hole 1221 and blocks the top of one of the two photoelectric switches 9; when the distal end 622 abuts against the bottom wall of the groove 1231, the other of the two trigger parts 612 passes through the through hole 1221 and blocks the top of the other of the two photoelectric switches 9.

[0097] Specifically, when the cleaning member 3 rises to the maximum height, one of the two trigger parts 612 blocks the top of one of the two photoelectric switches 9, so that the photoelectric switch 9 is triggered and the driving member 4 stops working; when the cleaning member 3 needs to be lowered, the driving member 4 works, the driving shaft rotates along the second direction, the cleaning member 3 descends to the mopping position, and the other of the two trigger parts 612 blocks the top of the other of the two photoelectric switches 9, so that the photoelectric switch 9 is triggered. At this time, the driving shaft rotates in the first direction to start the mode of cleaning the floor.

[0098] It should be noted that, in some embodiments, the main body 61 is a rod-shaped member, and the axial direction of the main body 61 is consistent with the axial direction of the cleaning member 3, the two cams 62 are respectively arranged at both ends of the main body 61 along its axial direction, the triggering portion 612 is two plate-shaped members formed on the outer periphery of the main body 61, and the plate surface direction of the triggering portion 612 is consistent with the radial direction of the main body 61, and the end surface of the triggering portion 612 facing the photoelectric switch 9 can be an arc surface or a fan-shaped surface. Here, the shape of the triggering portion 612 is not specifically limited.

[0099] Since the cleaning bracket 2 will also move up and down relative to the fixed frame structure 1 during the lifting and lowering process of the cleaning member 3, in order to improve the stability of the cleaning member 3 during the rising or falling process, in some embodiments, a guide structure can be set between the cleaning bracket 2 and the fixed frame structure 1 to play a certain guiding role in the relative movement between the cleaning bracket 2 and the fixed frame structure 1 in the up and down directions.

[0100] Therefore, please continue to see Figure 20 to Figure 23 , Fig. 20 A schematic diagram of the matching relationship between the first fixing frame and the cleaning bracket in the cleaning assembly provided in an embodiment of the present application, Fig.21 for Fig. 20 Cross-sectional view along the GG direction, Fig. 22 for Fig.21 The enlarged schematic diagram of the local structure at H in the middle. Fig.23 for Fig. 20 Cross-sectional view along direction II. In some specific embodiments, a guide sleeve 112 is provided on the side of the first fixed frame 11 facing the cleaning bracket 2. Specifically, the top end of the guide sleeve 112 extends upward from the first fixed frame 11, and the bottom end of the guide sleeve 112 extends downward from the first fixed frame 11. A guide column 213 is provided on the side of the bracket body 21 facing the first fixed frame 11. The guide column 213 extends into the guide sleeve 112, and the guide column 213 and the guide sleeve 112 slide in the up and down directions. In this way, during the lifting and lowering process of the cleaning member 3, it can play a certain guiding role in the movement between the cleaning bracket 2 and the fixed frame structure 1, thereby improving the stability of the cleaning member 3 during the lifting and lowering process.

[0101] In order to further improve the stability of the cleaning member 3 during the ascending or descending process, in some optional embodiments, a plurality of guide sleeves 112 may be provided on one side of the bracket body 21 of the first fixing frame 11, and a plurality of guide posts 213 may be provided on the side of the bracket body 21 facing the first fixing frame 11; one guide post 213 corresponds to one guide sleeve 112. In this way, the stability of the cleaning member 3 during the ascending or descending process can be further improved.

[0102] In this embodiment, the guide sleeve 112 and the guide column 213 can be two, respectively. The two guide sleeves 112 are spaced apart along the axial direction of the cleaning member 3 and are symmetrically distributed about the central axis of the cleaning member 3. The two guide columns 213 are spaced apart along the axial direction of the cleaning member 3 and are symmetrically distributed about the central axis of the cleaning member 3. In this way, the cleaning member 3 is more stable during the lifting process.

[0103] In some embodiments, in order to improve the structural compactness of the cleaning assembly 10, the second fixing frame 12 can be located between the two guide columns 213, that is, the rotating shaft 5 needs to pass through a guide column 213, the second fixing frame 12 and another guide column 213 in sequence to be rotatably connected to the cleaning bracket 2.

[0104] For details, see Figure 24 to Figure 26 , Fig.24 A three-dimensional structural schematic diagram of the matching relationship between the second fixing frame and the cleaning bracket in the cleaning assembly provided in an embodiment of the present application, Fig.25 for Fig.24 Cross-sectional view along JJ direction, Fig.26 for Fig.25 A schematic diagram of the enlarged local structure at K in the middle. As shown in the figure, in the present embodiment, in order to realize the positioning between the cleaning bracket 2 and the fixed frame structure 1 during the lifting and lowering process of the cleaning member 3, a receiving groove 214 can be provided on the top surface of the bracket body 21, and the abutting portion 123 can be located in the receiving groove 214. Since there are two abutting portions 123, there are also two receiving grooves 214, and one abutting portion 123 corresponds to one receiving groove 214. In this way, during the lifting and lowering process of the cleaning member 3, the receiving groove 214 and the abutting portion 123 slide and cooperate in the up and down directions, so that the cleaning bracket 2 and the fixed frame structure 1 can be effectively positioned, and the stability of the cleaning member 3 during the lifting and lowering process is improved.

[0105] In this embodiment, the guide column 213 can be composed of two parts. Fig. 27 and Fig.28 , Fig. 27 An exploded view of a cleaning bracket in a cleaning assembly provided in an embodiment of the present application, Fig.28 for Fig. 27 The enlarged schematic diagram of the local structure at L in the figure. Fig. 27 and Fig.28 As shown, and referring to the previous drawings, in some embodiments, the guide column 213 may include an adapter sleeve 2131 and an adapter column 2132, wherein the adapter sleeve 2131 is integrally formed with the bracket body 21 and is located at the top of the bracket body 21, and the adapter column 2132 is disposed in the adapter sleeve 2131 and is detachably connected to the adapter sleeve 2131.

[0106] Among them, the adapter sleeve 2131 is formed with a first notch 2133 and a second notch 2134 at both ends along the axial direction of the cleaning member 3, the first notch 2133 is located on the side facing the other guide column 213, and the second notch 2134 is located on the side away from the other guide column 213, and the side of the adapter column 2132 facing the other guide column 213 has a rotating portion 2135, and a rotating shaft hole 2136 is formed on the rotating portion 2135, and the rotating shaft hole 2136 passes through the adapter column 2132 in the axial direction of the cleaning member 3, and the rotating shaft 5 passes through the two rotating shaft holes 2136 and is rotatably connected to the two guide columns 213.

[0107] In order to realize the detachable connection between the adapter column 2132 and the adapter sleeve 2131, in some embodiments, the top of the adapter column 2132 is provided with connecting plates 2137 on both sides along the front-to-back direction, the thickness direction of the connecting plates 2137 is consistent with the up-down direction, and the connecting plates 2137 are provided with a fourth connecting hole 2138. Accordingly, the top of the adapter column 2132 is formed with two positioning cavities 2139 distributed along the front-to-back direction, and the bottom wall of the positioning cavity 2139 is provided with a fifth connecting hole 2140. Threaded fasteners such as screws can sequentially connect the adapter sleeve 2131 and the adapter column 2132 detachably. It should be noted that in some other embodiments, other detachable connection methods can be used between the adapter sleeve 2131 and the adapter column 2132, which will not be introduced one by one here.

[0108] Please continue to see Figure 29 to Figure 31 , Fig.29 for Figure 1 Another partial structural diagram of Fig.30 for Fig.29 The enlarged schematic diagram of the local structure at M in the middle. Fig.31A schematic diagram of the structure of the balance member in the cleaning assembly provided by the embodiment of the present application. It should be noted that, since the cam member 6 and the second fixed frame 12 are clearance-fitted, that is, the cam member 6 and the second fixed frame 12 are not tightly fitted, the cleaning member 3 may swing during the lifting process, which may cause the cleaning member 3 to have inconsistent heights at both ends during the lifting process. Therefore, in order to avoid this phenomenon, a balance member 30 can be provided, wherein the two ends of the balance member 30 are respectively rotatably connected to the cleaning bracket 2, and the two ends of the balance member 30 are respectively located on opposite sides of the center of the cleaning bracket 2; at least part of the structure of the balance member 30 located between its two ends is pressed against the fixed frame structure 1, specifically, at least part of the structure of the balance member 30 located between its two ends is pressed against the second fixed frame 12, and the balance member 30 is used to drive the two ends of the cleaning bracket 2 along its length direction to be in the same horizontal plane during the lifting process of the cleaning bracket 2. In this way, through the setting of the balance member 30, the balance member 30 can always exert a force on the second fixed frame 12, so that the height inconsistency of the cleaning member 3 along its axial ends can be avoided to a certain extent during the lifting process of the cleaning member 3.

[0109] It should be noted that, in some optional embodiments, the corresponding ends of the cam 62 and the balancing member 30 can be cross-arranged, that is, in the length direction of the cleaning bracket 2, one cam 62 and one end of the balancing member 30 can be located between the other cam 62 and the other end of the other balancing member; in other optional embodiments, in the length direction of the cleaning bracket 2, the two cams 62 can also be located between the two ends of the balancing member 30; in other embodiments, in the length direction of the cleaning bracket 2, the two ends of the balancing member 30 can also be located between the two cams 62.

[0110] In this embodiment, in order to make the cleaning member 3 more stable during the lifting process, the two cams 62 are located between the two ends of the balancing member 30 in the length direction of the cleaning bracket 2. In this way, during the lifting process of the cleaning member 62, the cleaning member 3 can be further prevented from swinging to a certain extent, making the cleaning member 3 more stable during the lifting process.

[0111] Specifically, the balancing member 30 is a rod-shaped member, and the balancing member 30 includes two adapter rod segments 31 arranged at intervals along the axial direction of the cleaning member 3 and a crossing rod segment 32 connected between the two adapter rod segments 31. The axial direction of the adapter rod segment 31 is consistent with the axial direction of the cleaning member 3, and the end of the adapter rod segment 31 that is not connected to the crossing rod segment 32 is rotatably connected to the corresponding guide column 213. Specifically, the adapter sleeve 2131 has a first adapter portion 2150 extending away from the other guide column 213, and the top end of the first adapter portion 2150 forms a first adapter cavity 2151. In the same guide column 213, the adapter column 2132 has a second adapter portion 2160 extending out of the second notch 2134, and the bottom end of the second adapter portion 2160 forms a second adapter cavity 2161. The first adapter cavity 2151 and the second adapter cavity 2161 are snapped together to form an adapter hole rotatably connected to the adapter rod segment 31.

[0112] The adapter hole formed by the first adapter cavity 2151 and the second adapter cavity 2161 being buckled together is located below the rotating shaft hole 2136 .

[0113] Furthermore, the crossing rod segment 32 includes two first transition rod segments 321, two second transition rod segments 322 and one main rod segment 323, wherein the axial direction of the first transition rod segment 321 is consistent with the front-to-back direction, the axial direction of the second transition rod segment 322 and the axial direction of the first transition rod segment 321 have an angle, the axial direction of the main rod segment 323 is consistent with the axial direction of the cleaning member 3, the two first transition rod segments 321 and the two second transition rod segments 322 are respectively arranged at both ends of the main rod segment 323, and the first transition rod segment 321 is connected between the end of the transfer rod segment 31 and the main rod segment 323.

[0114] During the lifting and lowering process of the cleaning member 3, since the balancing member 30 is rotatably connected to the cleaning bracket 2, the balancing member 30 will rotate relative to the cleaning bracket 2. When the cleaning member 3 performs normal cleaning work, the cleaning member 3 does not lift or lower, and the balancing member 30 is in a stationary state. At this time, in order to limit the position of the balancing member 30, in some optional embodiments, the second fixing frame 12 further includes an extension portion 126, and the extension portion 126 is connected to any side of the main body portion 122 along the front and rear direction of the cleaning device. Specifically, the extension portion 126 is connected to the main body portion 122. The main rod section 323 is pressed against the bottom wall of the concave cavity 1261, and the main rod section 323 can move in the concave cavity 1261 along the front-rear direction of the cleaning device. Specifically, when the cleaning member 3 rises, the balancing member 30 rotates, and at this time, the main rod section 323 moves forward in the concave cavity 1261, that is, moves in a direction close to the main body 122; when the cleaning member 3 descends, the balancing member 30 rotates, and at this time, the main rod section 323 moves backward in the concave cavity 1261, that is, moves in a direction away from the main body 122. In this way, by providing the concave cavity 1261 on the second fixing frame 12, when the cleaning member 3 cleans the ground, the position of the balancing member 30 can be restricted to avoid the middle part of the balancing member 30 hanging in the air, which affects the normal use of the cleaning device.

[0115] Among them, the front and rear sides of the cleaning equipment refer to Figures 1 to 3 as well as Fig.29 The length direction of the cleaning bracket 2 is Figures 1 to 7 The xx-axis direction is consistent.

[0116] Since the balancing member 30 rotates during the lifting of the cleaning member 3, it is necessary to make the top or bottom of the bottom end of the cavity 1261 open. In this embodiment, the bottom wall of the cavity 1261 extends downward, and the top of the cavity 1261 is open. In this way, the balancing member 30 can rotate normally during the lifting of the cleaning member 3.

[0117] It should be noted that the number of the extension portions 126 may be one, two, or three, etc. Here, the number of the extension portions 126 is not limited.

[0118] In some embodiments, there are at least two extensions 126, and at least two extensions 126 are located on opposite sides of the center of the cleaning bracket 2 in the length direction of the cleaning bracket 2. In this way, when the cleaning member 3 cleans the floor, the balancing member 30 can have a higher stability. The following will take the example of two extensions 126 as an example for further description.

[0119] Specifically, the two extending portions 126 are symmetrically arranged about the central axis of the cleaning member 3 , and the two extending portions 126 correspond to the two abutting portions 123 one by one, and the extending portions 126 are connected to the rear sides of the corresponding abutting portions 123 .

[0120] When the cleaning member 3 is cleaning the floor, if the cleaning effect of the cleaning member 3 needs to be ensured, the cleaning member needs to be effectively fitted to the floor. Therefore, when the cleaning member 3 is cleaning the floor, pressure can be generated on the cleaning member 3. There are two ways to generate pressure on the cleaning member 3. One is to directly apply pressure to the cleaning bracket 2 to generate pressure on the cleaning member 3; the other is to apply pressure to the cam member 6, thereby generating pressure on the cleaning bracket 2 through the cam member 6, and then generating pressure on the cleaning member 3.

[0121] Therefore, the cleaning assembly 10 provided in this embodiment may also include an elastic member 50. When pressure is directly applied to the cleaning bracket 2, the elastic member 50 is arranged between the fixed frame structure 1 and the cleaning bracket 2. Specifically, the elastic member 50 is arranged between the second fixed frame 12 and the bracket body 21. When pressure is applied to the cam member 6, the elastic member 50 is arranged between the fixed frame structure 1 and the cam member 6. Specifically, the elastic member 50 is arranged between the first fixed frame 11 and the cam member 6.

[0122] Please continue to see Figure 32 to Figure 35 , Fig.32 A schematic diagram of the connection structure between the spring in the cleaning assembly, the second fixing frame and the cleaning bracket provided in an embodiment of the present application, Fig.33 for Fig.32 Schematic diagram of the structure along the N direction, Fig.34 for Fig.33 The cross-sectional view of the structure along the OO direction, Fig.35 for Fig.34 The enlarged schematic diagram of the local structure at P in the middle. As an optional embodiment, when the elastic member 50 is arranged between the fixing frame structure 1 and the cleaning support 2, the elastic member 50 is a spring.

[0123] In order to improve the stability of the spring so that the pressure on the cleaning member 3 is relatively stable, in some embodiments, the second fixing frame 12 has a positioning column 127 protruding toward the bracket body 21, and a positioning groove 215 is formed on the side of the bracket body 21 facing the second fixing frame 12; one end of the spring is sleeved on the positioning column 127, and the other end of the spring is connected to the bottom wall of the positioning groove 215. In this way, the positions of the two ends of the spring can be limited, and the stability of the spring can be improved, so that the pressure on the cleaning member 3 is relatively stable, thereby improving the fit between the cleaning member 3 and the ground.

[0124] It should be noted that, in this embodiment, in order to facilitate the processing and forming of the second fixing frame 12 and to improve the structural compactness of the second fixing frame 12, the second connection hole 121 can be opened on the positioning column 127, wherein the top end of the positioning column 127 protrudes from the second fixing frame 12, and the bottom end of the positioning column 127 protrudes from the second fixing frame 12. In this way, it is not only convenient to process and form the second fixing frame 12, but also the structural compactness of the second fixing frame 12 can be improved, thereby improving the structural compactness of the cleaning assembly 10 provided in this embodiment; in addition, the structural strength at the second connection hole 121 can also be improved.

[0125] The positioning groove 215 may also be a column 216 formed on the top of the bracket body 21, and the positioning groove 215 is formed by cutting a groove on the column 216. In this way, the structural strength of the positioning groove 215 can be improved.

[0126] Please continue to see Figure 36 to Figure 39 , Fig.36 This is a schematic diagram of the connection structure between the torsion spring, the first fixing frame and the cam member in the cleaning assembly provided in an embodiment of the present application. Fig.37 for Fig.36 A magnified schematic diagram of the local structure at the middle Q. Fig.38 for Fig.37 Cross-sectional view along RR direction, Fig.39 for Fig.38 The enlarged schematic diagram of the local structure at S. As another optional implementation, the elastic member 50 can be disposed between the first fixing frame 11 and the cam member 6, and the elastic member 50 is a torsion spring.

[0127] Specifically, in order to limit the position of the torsion spring, a slot 113 can be formed on the first fixed frame 11. Specifically, the bottom wall of the slot 113 extends forward, and in order to ensure the deformation of the torsion spring, an opening 114 can be formed at the top of the slot 113; the torsion spring includes a torsion spring body 51 and an elastic arm 52, the torsion spring body 51 is inserted into the slot 113, the elastic arm 52 is connected to the lower end of the torsion spring body 51, and the bottom of the elastic arm 52 abuts against the cam member 6.

[0128] Furthermore, in order to increase the pressure applied by the elastic arm 52 to the cam member 6 and to ensure the stability of the pressure applied to the cam member 6, in some embodiments, a downwardly recessed portion 521 is formed on the elastic arm 52, and the recessed portion 521 abuts against the cam member 6. Specifically, the recessed portion 521 can abut against the pin or pin connecting the cam member 6 and the rotating shaft 5 through the third connecting hole 623. In this way, the pressure applied by the torsion spring to the cam member 6 can be relatively stable, so that the cleaning member 3 can be effectively fitted to the ground.

[0129] Since the cleaning member 3 is relatively long along its axial direction, in this embodiment, two elastic members 50 can be provided, and the two elastic members 50 are spaced apart along the axial direction of the cleaning member 3, and the two elastic members 50 are symmetrically arranged about the central axis of the cleaning member 3. In this way, the pressure received by each part of the cleaning member 3 can be more uniform, thereby improving the cleaning effect of the cleaning member 3.

[0130] Specifically, when the elastic member 50 is a spring, the two springs are arranged in one-to-one correspondence with the two positioning columns 127 located on the front side; when the elastic member 50 is a torsion spring, two slots 113 corresponding to the two torsion springs can be arranged on the first fixing frame 11.

[0131] like Figures 1 to 4 As shown, since the cleaning member has a mop, when the cleaning member 3 cleans the floor, the mop will absorb sewage. In order to remove the sewage on the mop, a scraper bar 7 can be provided at the rear side of the cleaning member 3. The scraper bar 7 is used to squeeze or scrape the sewage on the mop, and the cleaned sewage will flow into the sewage tank. Here, the scraper bar 7 is not described in detail.

[0132] The scraper strip 7 can be detachably connected to the bracket body 21 by means of threaded fasteners or the like, or can be snap-connected to the bracket body 21 by means of buckles or the like.

[0133] Furthermore, in order to realize the transmission connection between the drive shaft and the cleaning member 3 and the transmission connection between the drive shaft and the rotating shaft 5, the cleaning assembly 10 provided in this embodiment may also include a reduction box 8 arranged on the bracket body 21, the input end of the reduction box 8 is connected to the drive shaft, and the rotating shaft 5 and the cleaning member 3 are both connected to the output end of the reduction box 8. Specifically, an installation cavity 212 located outside the bracket body 21 is formed at one end of the bracket body 21 along the axial direction of the cleaning member 3, and the reduction box 8 is installed in the installation cavity 212. It should be noted that a gear transmission assembly may be provided inside the reduction box 8, which drives the cleaning member 3 to rotate or drives the cleaning member 3 and the rotating shaft 5 to rotate together through the transmission between the gears. Here, the internal structure of the reduction box 8 is not introduced in detail.

[0134] It should be noted that, in some other embodiments, the reduction box 8 can be replaced by other transmission structures, such as a pulley transmission structure or a chain transmission structure, etc. Here, there is no specific limitation on the type of transmission structure.

[0135] The cleaning assembly 10 provided in the present embodiment, when the cleaning member 3 needs to clean the floor, the driving member 4 is operated to make the driving shaft rotate in the first direction. For example, at this time, the driving shaft drives the cleaning member 3 to rotate in the positive direction so that the cleaning member 3 cleans the floor. At this time, the rotating shaft 5 does not rotate; when the cleaning member 3 needs to be raised, the driving member 4 is operated to make the driving shaft rotate in the second direction. At this time, the driving shaft drives the cleaning member 3 to rotate in the opposite direction and drives the rotating shaft 5 to rotate. When the rotating shaft 5 rotates, the cam member 6 rotates. When the cam member 6 rotates, it drives the cleaning member 3, the cleaning bracket 2, etc. to rise. When the near rest end 621 abuts against the bottom wall of the groove 1231, a trigger portion 612 blocks the top of a photoelectric switch 9. At this time, it means that the cleaning member 3 rises to the highest position, the photoelectric switch 9 is triggered, and the driving member 4 stops working.

[0136] When the cleaning member 3 needs to be lowered, the driving member 4 works, and the driving shaft continues to rotate in the second direction.
