[0042] Example

[0043] In this embodiment, a window cleaning machine is provided, which is used for cleaning a surface 10 to be cleaned having a frame 20 .

[0044] Reference Figure 1 The frame 20 has a first surface 21 and a second surface 22, and there is a height difference between the second surface 22 and the surface to be cleaned 10, and the first surface 21 connects the second surface 22 and the surface to be cleaned 10. For a window, the surface to be cleaned 10 is the surface of the glass, the first surface 21 is the side surface of the frame 20, and the second surface 22 is the end surface of the frame 20. The side surface of the frame 20 is located between the surface of the glass and the end surface of the frame 20 (that is, the first surface 21 is located between the surface to be cleaned 10 and the second surface 22).

[0045] like Figure 2-Figure 6 As shown, in this embodiment, the window cleaning machine includes a main body 100, a first type of cleaning element 210 and a second type of cleaning element 220, and both the first type of cleaning element 210 and the second type of cleaning element 220 are installed on the main body 100. Among them, the first type of cleaning element 210 is used to clean the surface to be cleaned 10, the second type of cleaning element 220 is at least used to clean the second surface 22, and at least one of the first type of cleaning element 210 and the second type of cleaning element 220 is used to clean the first surface 21.

[0046] During the process of wiping the window, the window cleaning machine can clean the glass and the frame 20 through the cooperation between the first type of cleaning elements 210 and the second type of cleaning elements 220, thereby achieving comprehensive cleaning of the window.

[0047] like Figure 3 As shown, the window cleaning machine includes a main body 100 , and the main body 100 is equipped with a fan 110 , a bracket 120 , a travel drive device 130 , a travel disc 140 , a first type of cleaning element 210 and a second type of cleaning element 220 .

[0048] The fan 110 is used to provide negative pressure so that the window cleaning machine can be adsorbed on the surface 10 to be cleaned.

[0049] The bracket 120 is used to install and position the fan 110 , the travel drive device 130 , etc.

[0050] The travel drive device 130 is used to drive the travel disc 140 to move, thereby enabling the window cleaning machine to travel on the surface to be cleaned 10. There are two travel discs 140.

[0051] The first type of cleaning elements 210 are installed on the traveling disc 140 . When the traveling disc 140 moves, it drives the first type of cleaning elements 210 to move synchronously, thereby making the first type of cleaning elements 210 wipe.

[0052] The second type cleaning element 220 is at least used to clean the second surface 22. The structure of the second type cleaning element 220 will be described later.

[0053] The main body 100 includes an upper cover 101 and a bottom shell 102, and the upper cover 101 and the bottom shell 102 are detachably connected by screw connection, clamping, etc. Among them, the fan 110, the bracket 120, the travel drive device 130 and the second type of cleaning element 220 are all installed inside the main body 100, and the travel disc 140 and the first type of cleaning element 210 are installed outside the main body 100.

[0054] In this embodiment, the state of the second type cleaning element 220 includes a first state and a second state, and the second type cleaning element 220 can switch between the first state and the second state. In the first state, the second type cleaning element 220 is retracted in the window cleaning machine; in the second state, the second type cleaning element 220 is extended outside the window cleaning machine to clean the second surface 22. The main body 100 is provided with an opening 103 corresponding to the second type cleaning element 220, and the second type cleaning element 220 is extended outside the window cleaning machine through the opening 103. The opening 103 and the second type cleaning element 220 can correspond one to one.

[0055] The window cleaning machine is used to identify the height of the frame 20, and control the position of the second type cleaning element 220 extending from the window cleaning machine according to the identified height of the frame 20, and press it on the second surface 22 to clean the second surface 22. The height of the frame 20 can be determined by a sensor.

[0056] The window cleaning machine controls the position of the second type of cleaning elements 220 according to the height of the frame 20 so that the second type of cleaning elements 220 are pressed onto the second surface 22 . When the window cleaning machine translates along the frame 20 , the second type of cleaning elements 220 can clean the second surface 22 .

[0057] like Figure 4-Figure 6As shown, a functional component 300 is provided in the window cleaning machine, and the functional component 300 is used to provide at least a first movement and a second movement for the second type cleaning element 220, the first movement is used to switch the movement of the second type cleaning element 220 in the direction of approaching and moving away from the surface 10 to be cleaned, and the second movement is used to switch the movement of the second type cleaning element 220 between the inside and the outside of the window cleaning machine. Figure 4 , the direction indicated by the arrow x is parallel to the direction of the first movement, and the direction indicated by the arrow y is parallel to the direction of the second movement.

[0058] The functional component 300 is installed in the installation shell 301, wherein the installation shell 301 is detachably provided with a shell cover 302, and the shell cover 302 is used to seal the inner cavity of the installation shell 301. The installation shell 301 and the shell cover 302 can be detachably connected by means of snap connection, screw connection, etc.

[0059] The mounting shell 301 is provided with a notch 303 , and the notch 303 is used for the second type cleaning element 220 to pass through, wherein the second type cleaning element 220 can extend out of or retract into the mounting shell 301 through the notch 303 .

[0060] The functional assembly 300 includes an action member 310, a connecting rod 320 and a traction member 330. The action member 310 is disposed on the connecting rod 320. Both ends of the traction member 330 are disposed on the action member 310 and the connecting rod 320 respectively. The second type of cleaning element 220 is connected to the traction member 330. The movement form of the traction member 330 on the connecting rod 320 is changed to drive the second type of cleaning element 220 to realize the first movement and the second movement.

[0061] When the actuating member 310 and the traction member 330 move on the connecting rod 320 and the distance between the actuating member 310 and the traction member 330 is kept unchanged, the traction member 330 moves in a first motion form, and the second type of cleaning element 220 performs a first motion; when the actuating member 310 and the traction member 330 move on the connecting rod 320 and the distance between the actuating member 310 and the traction member 330 is kept changed, the traction member 330 moves in a second motion form, and the second type of cleaning element 220 performs a second motion.

[0062] In this embodiment, when the traction member 330 moves in the first motion form, the traction member 330 and the action member 310 move synchronously, that is, the motion states of the two remain consistent; when the traction member 330 moves in the second motion form, the motion states of the traction member 330 and the action member 310 are not synchronized.

[0063] When the distance between the actuating member 310 and the traction member 330 decreases, the end of the traction member 330 connected to the actuating member 310 moves on the actuating member 310 in a direction away from the connecting rod 320, so as to drive the second type of cleaning element 220 to extend out of the window cleaning machine; when the distance between the actuating member 310 and the traction member 330 increases, the end of the traction member 330 connected to the actuating member 310 moves on the actuating member 310 in a direction close to the connecting rod 320, so as to drive the second type of cleaning element 220 to retract into the window cleaning machine.

[0064] like Figure 4-Figure 6 As shown, in this embodiment, the connecting rod 320 includes a first nut seat 321, a first screw rod 322, and a second screw rod 323, wherein the first nut seat 321 is threadedly connected to the first screw rod 322, and the first screw rod 322 and the second screw rod 323 are coaxially arranged.

[0065] One end of the traction member 330 is rotatably connected to the first nut seat 321, and the other end of the traction member 330 is connected to the second type cleaning element 220. The second type cleaning element includes a connecting plate 221 and a wiping member 222, and the wiping member 222 can be fixed to the connecting plate 221 by means of Velcro or the like, and one end of the connecting plate 221 is connected to the traction member 330 by means of a pin connection, a clamping connection, a welding connection, a bolt connection, or the like.

[0066] The action member 310 is provided with a sliding groove 311, wherein the traction member 330 and the second type cleaning element 220 are both slidably connected to the sliding groove 311. For example, the traction member 330 and the second cleaning element may be provided with a sliding shaft, wherein the sliding shaft is inserted into the sliding shaft, thereby achieving a slidable connection.

[0067] The actuating member 310 includes a second nut seat 312 , wherein the second nut seat 312 is threadedly connected to the second screw rod 323 , wherein a limiting member 324 is provided on the second screw rod 323 , and the limiting member 324 is used to limit the movable range of the second nut seat 312 on the second screw rod 323 .

[0068] The first screw rod 322 and the second screw rod 323 are both rotatably mounted in the mounting shell 301. A driving motor 340 is also disposed in the mounting shell 301, wherein a driving gear 341 is mounted on the output shaft of the driving motor 340. The first screw rod 322 is provided with a first driven gear 342 and a second driven gear 343, which are coaxial and mesh with the driving gear 341. When the driving motor 340 is started, the driving gear 341 rotates, thereby driving the first driven gear 342 and the second driven gear 343, so that the first screw rod 322 rotates.

[0069] The second screw rod 323 is provided with an electromagnetic clutch 344. When the electromagnetic clutch 344 is not activated, the second screw rod 323 and the second driven gear 343 are in a separated state, at which time, the motion states of the first screw rod 322 and the second screw rod 323 are independent of each other, that is, when the first screw rod 322 rotates, the second screw rod 323 will remain stationary; after the electromagnetic clutch 344 is activated, the second screw rod 323 is coupled with the second driven gear 343, at which time, the motion states of the first screw rod 322 and the second screw rod 323 are related to each other, that is, when the first screw rod 322 rotates, the second screw rod 323 will rotate synchronously with the first screw rod.

[0070] Reference Figure 4-Figure 7 When the functional component 300 is in the initial state, the second nut seat 312 of the action member 310 is located at the top of the second screw rod 323, and the first nut seat 321 is located in the middle of the first screw rod 322. When the window cleaning machine runs to the frame 20 and measures the height and width of the frame 20 through the sensor, the drive motor 340 starts to work and the electromagnetic clutch 344 is started: under the action of the gear mechanism, the first screw rod 322 and the second screw rod 323 rotate synchronously, so that the first nut seat 321 and the second nut seat 312 move synchronously. At this time, the traction member 330 moves in the first motion form, and the second type cleaning element 220 performs the first motion.

[0071] In one embodiment, the operating stroke of the action member 310 and the second nut seat 312 is D, and the operating stroke of the first nut seat 321 is E, wherein D>E. B and C represent the height and width of the frame 20, respectively. After the window cleaning machine reaches the frame 20, the electromagnetic clutch 344 is powered on, and the drive motor 340 drives the first nut seat 321 and the second nut seat 312 to move simultaneously, and the second type of cleaning element 220 is driven to A, thereby corresponding to the height of the frame 20; then the electromagnetic clutch 344 is powered off, and the drive motor 340 drives the first nut seat 321 to move upward. At this time, the traction member 330 moves in the second motion form, and the second type of cleaning element 220 performs the second motion, thereby making the width C of the frame 20.

[0072] After wiping the frame 20, the first nut seat 321 moves downward, driving the second type cleaning element 220 to be retracted into the mounting shell 301, and then the electromagnetic clutch 344 is energized, and the drive motor 340 drives the first screw rod 322 and the second screw rod 323 to rotate simultaneously, thereby driving the first nut seat 321 and the second nut seat 312 to reset simultaneously. In this embodiment, the motion states of the first screw rod 322 and the second screw rod 323 driven by a drive motor 340 are mutually related, realizing the switching of multiple motion forms, reducing the amount of driving devices used and reducing the manufacturing cost.

[0073] like Figure 4-Figure 6As shown, a guide rod 350 is fixedly arranged inside the mounting shell 301, a first connection hole 3210 is arranged on the first nut seat 321, and a second connection hole 3120 is arranged on the second nut seat 312, wherein the guide rod 350 passes through the first connection hole 3210 and the second connection hole 3120. The first connection hole 3210 and the second connection hole 3120 are both slidably connected with the guide rod 350. When the first screw rod 322 rotates, the first nut seat 321 can only make a linear motion and will not rotate under the action of the guide rod 350; when the second screw rod 323 rotates, the second nut seat 312 can only make a linear motion and will not rotate under the action of the guide rod 350.

[0074] In this embodiment, when the window cleaning machine cleans the frame 20, the second type of cleaning element 220 cleans the second surface 22, and the first type of cleaning element 210 cleans the first surface 21. The first type of cleaning element 210 and the second type of cleaning element 220 can perform cleaning work at the same time, thereby improving the cleaning efficiency.

[0075] At least one of the first type cleaning element 210 and the second type cleaning element 220 is used to clean the first surface 21, including the following forms:

[0076] In the first form, the second type of cleaning elements 220 clean the first surface 21 before the first type of cleaning elements 210;

[0077] In the second form, the first type of cleaning element 210 cleans the first surface 21 before the second type of cleaning element 220;

[0078] In a third form, the first type cleaning element 210 and the second type cleaning element 220 divide the first surface 21 into areas and clean them separately.

[0079] In actual operation, the user can choose the first form, the second form or the third form according to the needs.

[0080] In this embodiment, the second type of cleaning element 220 cooperates with the first type of cleaning element 210 to clean the second surface 22, including: the first type of cleaning element 210 cleans the second surface 22 once, and the second type of cleaning element 220 cleans the second surface 22 again; the second type of cleaning element 220 cleans the second surface 22 once, and the first type of cleaning element 210 cleans the second surface 22 again.

[0081] By performing the above cleaning steps, the cleaning effect can be effectively improved.

[0082] In this embodiment, there are a plurality of second-type cleaning elements 220. When the window cleaning machine cleans the frame 20, the window cleaning machine controls the working number of the second-type cleaning elements 220 according to the identified positions and number of the frames 20.

[0083] Reference Figure 8 The frame 20 includes a first frame portion 23, a second frame portion 24, a third frame portion 25 and a fourth frame portion 26 which are connected in sequence, wherein corner areas are formed between the first frame portion 23 and the second frame portion 24, between the second frame portion 24 and the third frame portion 25, between the third frame portion 25 and the fourth frame portion 26, and between the fourth frame portion 26 and the first frame portion 23.

[0084] For example, when the window cleaning machine is at the P1 position, at this time, the window cleaning machine is close to the corner area of ​​the frame 20, and by controlling the posture of the window cleaning machine, the two second-type cleaning elements 220 correspond to the first frame portion 23 and the second frame portion 24 respectively, thereby synchronously cleaning the first frame portion 23 and the second frame portion 24;

[0085] For another example, when the window cleaning machine is in the P2 position, at this time, the window cleaning machine is close to the middle position of the third frame 25. By controlling the posture of the window cleaning machine, a second type of cleaning element 220 corresponds to the third frame 25, thereby cleaning the third frame 25.
