Description

Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a window cleaning machine and cleaning system. Background Technology

[0002] In existing technologies, after completing a cleaning task, window cleaning machines often need to return to a specific location to perform the next task. For example, they may walk to the windowsill to cross windows and clean the next one, or walk back to the starting point for the user to pick up. If the window cleaning machine continues to walk on a window that has already been cleaned, the cleaning components may soil the already cleaned window surface, resulting in a poor user experience. Utility Model Content

[0003] In view of this, embodiments of this application provide a window cleaning machine and a cleaning system to solve the problem that the window cleaning machine will dirty the window surface when it walks on a window that has already been cleaned.

[0062] An embodiment of the first aspect of this application provides a window cleaning machine for cleaning window surfaces. Please refer to... Figure 1 The window cleaning machine 100 includes a housing 10, a cleaning component 20, and a lifting component 30. The cleaning component 20 is movably connected to the housing 10; the lifting component 30 is connected between the housing 10 and the cleaning component 20, and is used to drive the cleaning component 20 to move up and down relative to the housing 10.

[0063] In addition, the window cleaning machine 100 also includes a suction cup assembly and a traveling assembly. The suction cup assembly is used to allow the window cleaning machine 100 to adhere to the glass surface, and the traveling assembly is used to allow the window cleaning machine 100 to move on the glass surface. The suction cup assembly and the traveling assembly can be arranged independently or integrated together.

[0064] The cleaning component 20 is used to clean the window surface. The cleaning component 20 is movably connected to the housing 10, meaning it can move relative to the housing 10 under the drive of the lifting component 30. Specifically, in the cleaning state, the cleaning component 20 contacts and cleans the window surface; in the non-cleaning state, the cleaning component 20 moves away from the window surface to avoid soiling the already cleaned window surface.

[0065] The structure of the lifting component 30 in this application is not limited, as long as it can drive the cleaning component 20 to rise and fall relative to the housing 10.

[0066] The lifting direction of the cleaning component 20 is as follows: Figure 1 The X direction, that is, the lifting direction of the cleaning component 20, is perpendicular to the window surface.

[0067] The beneficial effects of the window cleaning machine 100 provided in this application embodiment are as follows: The window cleaning machine 100 of this application includes a housing 10, a cleaning component 20, and a lifting component 30, with the lifting component 30 disposed between the housing 10 and the cleaning component 20. When cleaning of the window surface is required, the lifting component 30 drives the cleaning component 20 to descend relative to the housing 10, so that the cleaning component 20 is lowered to the window surface. When cleaning of the window surface is not required, the lifting component 30 drives the cleaning component 20 to rise relative to the housing 10, so that the cleaning component 20 leaves the window surface. Since the cleaning component 20 has left the window surface when cleaning is not required, even if the window cleaning machine 100 moves on a cleaned window, it will not soil the cleaned window surface, thus solving the problem that the window cleaning machine 100 would soil the cleaned window surface when moving on it.

[0068] Please refer to Figure 1 and Figure 2 In some embodiments, the lifting assembly 30 includes a drive device 31 and a cable 32, wherein the drive device 31 is disposed on the housing 10, the first end of the cable 32 is connected to the drive device 31, and the second end of the cable 32 is connected to the cleaning assembly 20.

[0069] The drive device 31 is mounted on the housing 10. The first end of the cable 32 is connected to the drive device 31, and the second end of the cable 32 is connected to the cleaning component 20. The drive device 31 drives the cable 32 to pull the cleaning component 20 away from the window surface. That is, the drive device 31 and the cable 32 work together to drive the cleaning component 20 to rise relative to the housing 10.

[0070] Understandably, cable 32 can be a rope, steel cable, etc.

[0071] Please refer to Figure 1 and Figure 3 In some embodiments, the lifting assembly 30 further includes an elastic element 33 disposed between the housing 10 and the cleaning assembly 20.

[0072] The elastic element 33 is disposed between the housing 10 and the cleaning component 20, and can apply an elastic force to the cleaning component 20 to bring the cleaning component 20 closer to the window surface. That is, the elastic element 33 is used to drive the cleaning component 20 to descend relative to the housing 10.

[0073] It is understood that the number of elastic elements 33 can be one or more. When there are multiple elastic elements 33, they can be arranged at intervals along the length direction of the cleaning assembly 20; or, they can be arranged at intervals along the width direction of the cleaning assembly 20; or, they can be distributed around the edge of the cleaning assembly 20; or, they can be arranged near the connection points between the second ends of the multiple cables 32 and the cleaning assembly 20. Here, the length direction of the cleaning assembly 20 refers to the Y direction, and the width direction of the cleaning assembly 20 is perpendicular to both the X and Y directions.

[0074] Understandably, the elastic element 33 can be a compression spring, leaf spring, etc.; of course, the elastic element 33 can also be a rubber element with a certain degree of elasticity.

[0075] In some embodiments, the lifting assembly 30 includes a drive device 31, a cable 32, and an elastic element 33, with the elastic element 33 disposed between the housing 10 and the cleaning assembly 20. The drive device 31 is mounted on the cleaning assembly 20, a first end of the cable 32 is connected to the drive device 31, and a second end of the cable 32 is connected to the housing 10.

[0076] Please refer to Figure 2 and Figure 4 In some embodiments, the drive device 31 includes a first drive motor 311 and a turntable 312 connected to the output shaft of the first drive motor 311, and the first end of the cable 32 is connected to the turntable 312.

[0077] For example, when the output shaft of the first drive motor 311 rotates in the forward direction, the turntable 312 rotates in the forward direction and winds the cable 32 to pull the cleaning component 20, causing the cleaning component 20 to rise relative to the housing 10. At this time, the elastic element 33 is compressed. When the output shaft of the first drive motor 311 rotates in the reverse direction, the turntable 312 rotates in the reverse direction, the cable 32 is released, and the cleaning component 20 descends relative to the housing 10 under the elastic force of the elastic element 33.

[0078] Based on the above technical solution, the first drive motor 311 drives the turntable 312 to rotate to wind the cable 32, so that the drive device 31 can be used for the larger lifting stroke of the cleaning component 20 without changing its size.

[0079] In some embodiments, the drive device 31 is a telescopic cylinder, and the first end of the cable 32 is connected to the telescopic rod of the telescopic cylinder. When the telescopic rod of the telescopic cylinder retracts, the telescopic rod drives the cable 32 to pull the cleaning component 20, causing the cleaning component 20 to rise relative to the housing 10, at which time the elastic element 33 is compressed. When the telescopic rod extends, the cable 32 is released, and under the elastic force of the elastic element 33, the cleaning component 20 descends relative to the housing 10. The telescopic cylinder can be a pneumatic cylinder or a hydraulic cylinder.

[0080] Please refer to Figure 4 and Figure 5 In some embodiments, multiple cables 32 are provided, and the second ends of the multiple cables 32 are connected to different positions of the cleaning component 20.

[0081] Understandably, the 32 cables can be set to two, three, four or more.

[0082] Understandably, the connection points between the second ends of the plurality of cables 32 and the cleaning assembly 20 can be arranged at intervals along the length direction of the cleaning assembly 20, wherein the length direction of the cleaning assembly 20 is the Y direction. For example, there are two cables 32, the first ends of the two cables 32 are connected to the drive device 31, and the connection points between the second ends of the two cables 32 and the cleaning assembly 20 are arranged at intervals in the Y direction.

[0083] Of course, the connection points of the second ends of the multiple cables 32 to the cleaning component 20 can also be arranged at intervals along the width direction of the cleaning component 20, wherein the width direction of the cleaning component 20 is the travel direction of the window cleaning machine 100.

[0084] Based on the above technical solution, multiple cables 32 are used to pull the cleaning component 20 together, so as to improve the stability of the cleaning component 20 when it is raised and lowered relative to the housing 10.

[0085] In some embodiments, a single cable 32 may also be provided.

[0086] Please refer to Figure 4 and Figure 5 In some embodiments, the first ends of multiple cables 32 are connected to the same drive device 31, that is, the drive device 31 simultaneously drives multiple cables 32 to pull the cleaning component 20.

[0087] For example, there are two cables 32, and the first ends of the two cables 32 are connected to the same drive device 31.

[0088] Based on the above technical solution, the number of drive devices 31 can be reduced, thus lowering costs; moreover, it can also ensure the consistency of the movement of multiple cables 32, which is beneficial for the lifting and lowering of the cleaning component 20.

[0089] In some embodiments, there are multiple drive devices 31, and the number of drive devices 31 is the same as the number of cables 32, that is, one cable 32 is driven by one drive device 31. For example, the number of drive devices 31 and the number of cables 32 are both two, one cable 32 is driven by one drive device 31, and the other cable 32 is driven by the other drive device 31.

[0090] In some embodiments, there are multiple drive devices 31, and the number of drive devices 31 is less than the number of cables 32, that is, some cables 32 share drive devices 31. For example, there are two drive devices 31 and three cables 32, one of which is driven by one drive device 31, and the other two cables 32 are driven by another drive device 31.

[0091] Please refer to Figure 4 and Figure 5 In some embodiments, the drive device 31 includes a first drive motor 311 and a turntable 312 connected to the output shaft of the first drive motor 311. Multiple turntables 312 are provided, and the first ends of multiple cables 32 are connected to the multiple turntables 312 in a one-to-one correspondence.

[0092] For example, two cables 32 are provided, and correspondingly, two turntables 312 are provided, wherein the two turntables 312 are arranged along the axial direction of the output shaft of the first drive motor 311. The first end of one cable 32 is connected to one turntable 312, and the first end of the other cable 32 is connected to the other turntable 312; that is, under the forward rotation of the output shaft of the first drive motor 311, the two turntables 312 can respectively wind the two cables 32.

[0093] For example, the turntable 312 is provided with a winding groove, and the cable 32 is wound in the winding groove.

[0094] Based on the above technical solution, multiple turntables 312 are arranged independently, which is relatively simple in structure and conducive to processing and forming.

[0095] In some embodiments, the drive device 31 includes a first drive motor 311 and a turntable 312 connected to the output shaft of the first drive motor 311. The turntable 312 has one and multiple winding positions, and the first ends of multiple cables 32 are connected to the multiple winding positions one by one.

[0096] For example, there are two cables 32, and correspondingly, there are two winding positions, wherein the two winding positions are arranged along the axial direction of the output shaft of the first drive motor 311. The first end of one cable 32 is connected to one winding position, and the first end of the other cable 32 is connected to the other winding position; that is, under the forward rotation of the output shaft of the first drive motor 311, the two winding positions can respectively wind the two cables 32.

[0097] For example, the winding position can be a winding groove, in which the cable 32 is wound.

[0098] Based on the above technical solution, the turntable 312 is provided, which is beneficial for assembly.

[0099] In some embodiments, the first ends of the plurality of cables 32 are connected to the same drive device 31, which is a telescopic cylinder, and the first ends of the plurality of cables 32 are all connected to the telescopic rod of the telescopic cylinder; that is, the contraction of the telescopic rod simultaneously drives the plurality of cables 32 to pull the cleaning component 20.

[0100] Please refer to Figure 4 and Figure 5 In some embodiments, the cleaning component 20 is provided with a curved limiting groove 21121, and the second end of the cable 32 is connected to the limiting groove 21121.

[0101] Understandably, the curve can be an arc, a broken line, etc., that is, the shape of the limiting groove 21121 is an arc, a broken line, etc.

[0102] Based on the above technical solution, the second end of the cable 32 is less likely to come out of the limiting groove 21121 in the direction perpendicular to the X direction, thereby improving the reliability of the second end of the cable 32 connected to the cleaning component 20.

[0103] Please refer to Figure 1 and Figure 2 In some embodiments, the window cleaning machine 100 further includes a first bracket 40 and a second bracket 50 disposed on the housing 10, and the lifting assembly 30 further includes a limiting sleeve 34 sleeved on the pull cable 32. The first end of the limiting sleeve 34 is fixed to the first bracket 40, and the second end of the limiting sleeve 34 is fixed to the second bracket 50. The length of the pull cable 32 is greater than the length of the limiting sleeve 34.

[0104] Understandably, the first bracket 40 can be integrally formed with the housing 10; or, the first bracket 40 can also be fixed to the housing 10 by means of fastener connection, snap-fit, etc.

[0105] Understandably, the second bracket 50 can be integrally formed with the housing 10; or, the second bracket 50 can also be fixed to the housing 10 by means of fastener connection, snap-fit, etc.

[0106] For example, the limiting sleeve 34 is a flexible sleeve, such as a plastic sleeve or a rubber sleeve. Of course, the limiting sleeve 34 can also be a rigid sleeve.

[0107] For example, the first end of the limiting sleeve 34 is snapped and fixed to the first bracket 40, and the second end of the limiting sleeve 34 is snapped and fixed to the second bracket 50.

[0108] The length of cable 32 is greater than the length of limiting sleeve 34, that is, part of cable 32 is wrapped and supported by limiting sleeve 34.

[0109] For example, there are two cables 32. Since the drive device 31 is located on the housing 10, one or two first brackets 40 can be provided, and two second brackets 50 can be provided. When one first bracket 40 is provided, the first ends of the two limiting sleeves 34 share the first bracket 40. Of course, when one cable 32 is provided, one first bracket 40 and one second bracket 50 can both be provided.

[0110] For example, the second support 50 is further away from the cleaning component 20 than the first support 40, which can be understood as the second support 50 being higher than the first support 40.

[0111] Based on the above technical solution, since part of the cable 32 is wrapped and supported by the limiting sleeve 34, this part of the cable 32 can be arranged arbitrarily, which is beneficial for the arrangement of the cable 32 between the housing 10 and the cleaning component 20.

[0112] In some embodiments, the lifting assembly 30 may not include the limiting sleeve 34. Since the cable 32 needs to remain taut during the process of pulling the cleaning assembly 20 upward, in order to adapt the cable 32 to the complex structure inside the housing 10 and facilitate the driving of the cable 32, a fixed pulley can be provided on the housing 10 at the position corresponding to the bend of the cable 32.

[0113] Please refer to Figure 4 and Figure 5 In some embodiments, the cleaning assembly 20 includes a frame 21 and a cleaning component 22 disposed on the frame 21. The frame 21 includes a rotating arm 211, and the frame 21 is rotatably connected to the housing 10 via the rotating arm 211. A lifting assembly 30 is connected between the housing 10 and the frame 21. The rotation axis A of the frame 21 is along... Figure 4 It extends in the Y direction.

[0114] The cleaning component 22 is mounted on the frame 21, meaning that the cleaning component 22 can rotate together with the frame 21 to achieve the lifting and lowering of the cleaning assembly 20.

[0115] For example, the cleaning component 22 is capable of reciprocating relative to the frame 21 in the Y direction. For instance, the frame 21 is equipped with a second drive motor 80, the output shaft of the second drive motor 80 is equipped with a second gear 81, and the cleaning component 22 is equipped with a second rack 90, which is arranged along the Y direction. When the second drive motor 80 drives the second gear 81 to rotate, the second gear 81 meshes with the second rack 90 to achieve reciprocating movement of the cleaning component 22 relative to the frame 21 in the Y direction.

[0116] Understandably, the cleaning component 22 may include a cleaning cloth, a cleaning brush, a cleaning sponge, or a squeegee, etc.

[0117] For example, the first end 2111 of the rotating arm 211 is rotatably connected to the housing 10, and the second end of the cable 32 is connected to the second end 2112 of the rotating arm 211; wherein, the second end of the cable 32 drives the second end 2112 of the rotating arm 211 to rise and fall, so as to realize the raising and lowering of the cleaning component 20.

[0118] The elastic element 33 is connected between the housing 10 and the frame 21. For example, when the elastic element 33 is a compression spring, one end of the compression spring abuts against the housing 10 and the other end of the compression spring abuts against the frame 21; when the elastic element 33 is a leaf spring, one side of the leaf spring abuts against the housing 10 and the other side of the leaf spring abuts against the frame 21.

[0119] The limiting groove 21121 is located at the second end 2112 of the rotating arm 211.

[0120] Based on the above technical solution, during the lifting and lowering process of the cleaning component 20 relative to the housing 10, the rotating arm 211 can be used to ensure that the cleaning component 20 does not shake, without the need for additional guide structures.

[0121] In some embodiments, multiple rotating arms 211 are arranged at intervals along the extension direction of the rotation axis A of the frame 21.

[0122] It is understood that two, three, or four or more rotating arms 211 can be arranged at intervals along the extension direction of the rotation axis A of the frame 21.

[0123] For example, there are two rotating arms 211, and correspondingly, there are two cables 32, with the second ends of the two cables 32 respectively connected to the second ends 2112 of the two rotating arms 211.

[0124] Based on the above technical solution, the stability of the cleaning component 20 rotating on the housing 10 can be guaranteed.

[0125] Please refer to Figure 1 and Figure 4In some embodiments, the window cleaning machine 100 further includes a first limiting member 60 disposed on the housing 10. The first limiting member 60 is used to limit the lowering position of the cleaning component 20 relative to the housing 10 and prevent the cleaning component 20 from lowering excessively.

[0126] For example, the first limiting member 60 is a limiting shaft arranged along the extension direction of the rotation axis A of the frame 21, and the limiting shaft is located below the rotating arm 211.

[0127] For example, the rotating arm 211 includes an arc-shaped segment located at the middle position of the rotating arm 211, and the limiting shaft is used to limit and cooperate with the arc-shaped segment of the rotating arm 211. When there are two rotating arms 211, the limiting shaft simultaneously cooperates with the arc-shaped segments of both rotating arms 211.

[0128] In some embodiments, the frame 21 does not include a rotating arm 211, and the frame 21 is guided and mounted on the housing 10 along the X direction. For example, the frame 21 is provided with a guide post, and the housing 10 is provided with a guide hole that guides and engages with the guide post; or, the housing 10 is provided with a guide post, and the frame 21 is provided with a guide hole that guides and engages with the guide post. The central axes of the guide post and the guide hole extend along the X direction.

[0129] The second end of the cable 32 is connected to the frame 21.

[0130] It can be understood that there can be one guide post and one guide hole; or there can be multiple guide posts and multiple guide holes.

[0131] Please refer to Figure 3 In some embodiments, the window cleaning machine 100 further includes a second limiting member 70 disposed on the housing 10, the second limiting member 70 being used to limit the rising position of the cleaning component 20 relative to the housing 10, so as to prevent the cleaning component 20 from rising excessively.

[0132] For example, the second limiting member 70 is a micro switch. During the rising process of the cleaning component 20, when the cleaning component 20 touches the micro switch, the micro switch sends a signal to the controller, and the controller controls the first drive motor 311 to stop working, that is, the cleaning component 20 stops rising.

[0133] For example, the second limiting member 70 is an optical coupler sensor, wherein the cleaning assembly 20 is provided with a blocking member. During the upward movement of the cleaning assembly 20, when the blocking member is between the transmitting end and the receiving end of the optical coupler sensor, the optical coupler sensor sends a signal to the controller, and the controller controls the first drive motor 311 to stop working, that is, the cleaning assembly 20 stops rising.

[0134] For example, the second limiting member 70 is a Hall sensor, and the cleaning assembly 20 is provided with a magnet. During the upward movement of the cleaning assembly 20, when the Hall sensor senses the magnetic field generated by the magnet, the optocoupler sensor sends a signal to the controller, and the controller controls the first drive motor 311 to stop working, that is, the cleaning assembly 20 stops rising.

[0135] For example, the second limiting member 70 can also be a limiting block. During the process of the cleaning component 20 rising, when the limiting block abuts against the cleaning component 20, the first drive motor 311 stalls and stops working, that is, the cleaning component 20 stops rising.

[0136] In some embodiments, the second limiting member 70 is disposed on the cleaning component 20. The second limiting member 70 can be a micro switch, an optocoupler sensor, a Hall sensor, or a limiting block, and its working principle is the same as above.

[0137] In some embodiments, the lifting assembly 30 includes a drive device 31 and a transmission mechanism, wherein the drive device 31 is disposed on the housing 10.

[0138] For example, the transmission mechanism is a lead screw and nut mechanism, which includes a lead screw and a nut threaded onto the lead screw. The lead screw extends along the lifting direction and is connected to the drive device 31. The lead screw is connected to the drive device 31, and the nut is connected to the cleaning component 20. The drive device 31 drives the lead screw to rotate, so that the nut moves along the lifting direction, thereby realizing the lifting of the cleaning component 20.

[0139] For example, the transmission mechanism is a gear and rack mechanism, which includes a first gear and a first rack meshing with the first gear. The first gear is connected to the drive device 31, and the first rack extends along the lifting direction and is connected to the cleaning component 20. The drive device 31 drives the first gear to rotate, so that the first rack moves along the lifting direction, thereby realizing the lifting of the cleaning component 20.

[0140] The direction of lifting is Figure 1 The X direction in the equation.

[0141] For example, the drive device 31 is a third drive motor.

[0142] In some embodiments, the lifting assembly 30 has a lowered position and a raised position during the lifting and lowering process relative to the housing 10. When the window cleaning machine 100 moves forward, the cleaning assembly 20 is in the lowered position, and when the window cleaning machine 100 moves backward, the cleaning assembly 20 is in the raised position. When the cleaning assembly 20 is in the lowered position, it contacts and cleans the glass surface; when the cleaning assembly 20 is in the raised position, it moves away from the glass surface.

[0143] The second aspect of this application proposes a cleaning system comprising a cleaning base station and a window cleaning machine 100 as described in the first aspect, wherein the cleaning base station is used to house the window cleaning machine 100.

[0144] Understandably, the cleaning base station can charge the window cleaning machine 100, replenish the cleaning fluid, clean and dry the cleaning components 22 of the window cleaning machine 100, and communicate with the window cleaning machine 100 (e.g., positioning, navigation).

[0145] The cleaning system employs any one or more embodiments of the window cleaning machine 100 described above, and thus has the beneficial effects of the embodiments described above, which will not be elaborated further here.

[0146] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application, and should all be included within the protection scope of this application.
