Description

Technical Field

[0001] This utility model belongs to the field of cleaning tool technology, and in particular relates to a window cleaning machine that can cross window frames. Background Technology

[0002] As people's living standards and housing standards continue to improve, more and more people live in high-rise buildings, making high-altitude window cleaning a very dangerous task. Indoor windows are relatively easy to clean and have a low risk factor, but outdoor windows are quite dangerous. People have to lean forward and stick their upper body out of the window while holding window cleaning tools, which is quite strenuous and dangerous, and the windows may not even be clean. Therefore, people need a product that can solve the problem of not having to use their hands, is safe, and can clean windows effectively to meet their practical needs.

[0003] To address this practical need, the machine needs to be fully or partially automated to solve the problem of outdoor window cleaning. Based on current technology, achieving this requires the machine to be equipped with mechanical and electrical automation technologies, as well as sensors capable of different functions. Finally, it also needs a central processing unit system. After receiving signals from the sensors, the central processing unit determines the machine's location and orientation, and then issues corresponding instructions to make the machine perform a series of actions based on the location and orientation.

[0004] In recent years, some window cleaning machines have appeared on the market. These machines operate through mechanical and electrical automation. Currently, there are square and oval automated window cleaning machines on the market, as well as window cleaning machines that use the principle of magnetic attraction between opposing forces. However, all of them require the machine to be removed after cleaning one window and then placed on another window, which is time-consuming and labor-intensive.

[0005] Problems existing in the prior art:

[0006] Both square and oval machines operate through machine automation and electrical automation principles, supplemented by sensors. However, these two types of machines have some shortcomings in practical use, specifically in the following nine aspects:

[0007] (1) The adsorption capacity is not strong, and the machine will slip from time to time during operation. In severe cases, it will fall off the glass.

[0008] (2) The surface should not have too much water. The surface should only be damp. If it is wet or has too much water, the machine will slip in place and will not proceed to the next step.

[0009] (3) The four corners of the window cannot be wiped. When the elliptical machine runs to the corner, it cannot wipe the four corners of the glass because the machine itself is elliptical. The square machine has a sensor at each corner, so the four corners cannot be wiped either.

[0010] (4) The glass surface should not be too dirty. If there is too much dust, rain stains, sand, dirt, etc., the machine will not be able to hold it and it will fall off.

[0011] (5) Excessive noise. Both machines are around 70 decibels. The noise is acceptable when wiping outdoor glass, but it is very loud when wiping indoor glass. It exceeds the normal speaking volume and is very noisy.

[0012] (6) The problem of low efficiency: the existing products on the market have relatively low working efficiency. This product uses a high-speed motor to provide power, which greatly improves working efficiency.

[0013] (7) The stains are stuck to the glass too tightly and are not easy to wipe off.

[0014] (8) Uneven water spraying.

[0015] (9) In the case of the machine falling unsafely, if the machine loses its grip and falls, the machine will be pulled down by the safety rope very stiffly and directly, which requires a lot of pulling force to hold the machine. This will cause great damage to the machine itself. At the very least, it will deform the internal structure of the machine. At worst, the machine and the safety rope will lose their connection and the machine will fall to the ground in free fall. This will cause a devastating blow to the machine. The machine will fall heavily to the ground and become scrap.

[0016] (10) The machine cannot automatically move from one window sash to another to work. After the glass of one window sash is cleaned, it needs to be manually removed and placed on the glass of another window sash before the machine can work, which is time-consuming and laborious.

[0017] Magnetic cleaning machines are not considered automated or semi-automated; they are still manual products and require manual operation when cleaning windows.

[0018] In practice, there are two identical-looking parts, each containing a magnet. Based on the principle of attraction between opposite magnetic fields, the two parts clamp the glass in the middle. Moving one part will cause the other part to move accordingly, thus achieving the purpose of wiping the glass. However, this product is still a manual operation and is not in the same league as the two machines mentioned above (square and oval). The only advantage of this product is that both the inside and outside of the glass are wiped simultaneously, but in terms of reducing repetitive labor, this product is not very meaningful.

[0019] Therefore, there is an urgent need for a fully automatic window cleaning machine that can solve the above problems. Utility Model Content

[0138] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0139] To better understand the purpose, structure, and function of this utility model, a more detailed description of this utility model is provided below with reference to the accompanying drawings.

[0140] Example 1

[0141] According to the embodiments of this application, it includes:

[0142] The housing 1 has an internal mounting cavity with a bottom opening. The housing 1 is an external protective component that provides mounting space for the other structures. The shape of the housing 1 is preferably rectangular, and the material is selected according to actual needs and is not limited here.

[0143] Telescopic module 2, which is located in the installation cavity and is fixedly connected to the housing 1, has a fixed end and a telescopic end. The fixed end and telescopic end refer to the part of the adsorption module that is adsorbed on the glass and the part of the lifting and rotating module connected to it, which is called the fixed end. The part of the adsorption module that is not adsorbed on the glass and the part of the lifting and rotating module connected to it is called the telescopic end.

[0144] The telescopic module includes:

[0145] The first linear guide 201 is located in the mounting cavity. Two first sliders 202 are provided on the first linear guide 201. The two first sliders 202 are fixedly connected to the lifting plate 301 of the lifting module 3.

[0146] The first motor 203 is either a stepper motor or a servo motor, preferably a servo motor, which can rotate forward and reverse. The first motor is located on the lifting plate of the lifting module located at the fixed end in the mounting cavity, and a gear is provided on its output end.

[0147] The first rack is mounted on the lifting plate 301 in the lifting module located at the telescopic end. It is fixedly connected to the lifting plate and meshes with the gear on the output end of the first motor.

[0148] That is, the first motor 203 drives the gear component to rotate forward or backward. Due to the meshing of the gear component with the first rack, the first rack causes the lifting module located on the telescopic end to move laterally in different directions, thus achieving the telescopic function; for example... Figure 17 and Figure 18 and Figure 19 As shown;

[0149] Lifting module 3, wherein the lifting module 3 is disposed within the mounting cavity;

[0150] It is connected to the telescopic end of the telescopic module 2, and has a lifting end on it;

[0151] It should be noted that the lifting module 3 is a modular structure, including:

[0152] The lifting plate 301 is a plate-shaped structure with a rectangular hole. The lifting plate 301 is located below the telescopic module 2. It is fixedly connected to the first slider 202 and the first rack 204. It can move laterally in the mounting cavity as the first rack 204 and the first slider 202 move laterally. In other words, the lifting plate 301 serves as the connecting carrier between the first rack 204 and the first slider 202.

[0153] The second linear guide 302 is a rod and roller structure. The second linear guide 302 is disposed on the base plate 401 of the rotating module 4 and is fixedly connected to the base plate 401 of the rotating module 4. The second linear guide 302 is arranged perpendicularly to the lifting plate 301 and is disposed on one side of the rectangular hole of the lifting plate 301.

[0154] The second slider is mounted on the second linear guide rail 302 and is slidably connected to the second linear guide rail 302. It can move longitudinally on the second linear guide rail 302. The second slider is fixedly connected to the lifting plate 301 on the lifting module 3.

[0155] The second rack 303 is mounted on the base plate 401 of the rotating module 4 and is fixedly connected to the base plate 401 of the rotating module 4. It can move longitudinally as the second slider moves longitudinally.

[0156] The second motor is either a stepper motor or a servo motor, preferably a servo motor, capable of forward and reverse rotation (not shown in the figure). The second motor is mounted on the lifting plate 301, and its output end has a gear component that meshes with the second rack 303. Because the gear component of the second motor meshes with the second rack 303, the rotation of the second motor drives the gear component to rotate, thereby causing the second rack 303 to drive the second slider to move longitudinally on the second linear guide rail 302, thus causing the rotating module 4 to move longitudinally. Figure 14 and Figure 15 and Figure 16 As shown;

[0157] Rotating module 4, which is located on the lifting end of lifting module 3 and has a rotating end thereon;

[0158] It should be noted that the rotating module 4 is a modular structure, including:

[0159] The base plate 401 has a plate-like structure. The support plate is located in the mounting cavity. Its top is connected to the lifting end of the lifting module 3, and a through hole is provided in its center.

A bearing 4001 is provided between the rotating shaft 402 and the base plate 401, and the rotating shaft 402 can rotate within the through hole of the base plate 401.

[0161] A rotating gear 403 is mounted on a rotating shaft 402 and is fixedly connected to the rotating shaft 402. An EPDM ring 504 of the adsorption module 5 is mounted on the rotating gear 403. In other words, the bottom of the rotating gear 403 is provided with an annular groove, and the EPDM ring 504 of the adsorption module 5 is located in the annular groove. The two are detachably connected.

[0162] The third motor 404 is either a stepper motor or a servo motor, preferably a servo motor, which can rotate forward and reverse. The third motor 404 is mounted on the base plate 401, and its output end passes through the base plate 401. The gear on the output end is meshed with the rotating gear 403.

[0163] The universal ball 405 is mounted on the base plate 401 via a connector. Its bottom is slidably connected to the top of the rotating gear 403. The universal ball 405 abuts against the rotating gear 403, thereby providing longitudinal support and preventing the rotating gear 403 from shifting. The number and arrangement of the universal balls 405 are selected according to actual needs and are not limited here.

[0164] The third motor 404 drives the rotating gear 403 to rotate, thereby causing the base plate 401 in the rotating module 4 to rotate, and under the action of the universal ball 405, it maintains horizontal rotation; Figure 12 and Figure 13 As shown,

[0165] Adsorption module 5, wherein the adsorption module 5 is disposed on the rotating end of the rotating module 4;

[0166] It should be noted that the adsorption module 5 is a modular structure, including:

[0168] The rotating shaft 402 is provided with a first air passage 4021 and a second air passage 4022, wherein the first ends of the first air passage 4021 and the second air passage 4022 are arranged longitudinally above the rotating shaft 402, the second end of the first air passage 4021 is located at the bottom of the rotating shaft 402, and the second end of the second air passage 4022 is located at the part of the rotating shaft 402 that penetrates the bottom plate 401.

[0169] The first solenoid valve 502 is located on the first sealing ring on the rotating shaft 402. It is connected to the first end of the first air passage 4021 and to the vacuum pump 501. It should be noted that the first solenoid valve 502 is connected to the outside when it is not energized.

[0170] The second solenoid valve 503 is located on the second sealing ring on the rotating shaft 402. It is connected to the first end of the second air passage 4022 and to the vacuum pump 501. It should be noted that the second solenoid valve 503 is connected to the outside when it is not energized.

[0171] It should be noted that a sealing ring 4002 and a sealing ring 4003 are provided at the connection between the first solenoid valve 502 and the second solenoid valve 503 and the first air passage 4021 and the second air passage 4022.

[0172] The EPDM ring 504 (which is a hollow ring structure) is located on the groove of the rotating gear 403. It has a flow end and is connected to the second end of the second air passage 4022 through the flow end. That is, the EPDM ring 504 is connected to the second end of the second air passage 4022 through a flexible connecting tube.

[0173] Under normal conditions, the EPDM ring 504 is in a semi-circular state. Both the first solenoid valve 502 and the second solenoid valve 503 are open to the outside. When adsorption is required, the second solenoid valve 503 is closed, preventing the vacuum pump 501 from drawing air from the EPDM ring 504. At this time, the inside of the EPDM ring 504 is open to the outside air, and the first solenoid valve 502 is connected to the vacuum pump 501. When the machine is placed on glass, the EPDM ring 504 contacts the glass. Because the EPDM ring 504 is elastic, the circular area formed by the glass and the EPDM ring 504—the central area of ​​the rotating gear 403—is isolated from the outside. When the vacuum pump 501 is connected through the first solenoid valve 502, it will draw air from the central circular area of ​​the rotating gear 403. Air is drawn into the glass, creating negative pressure in the central circular area of ​​the rotating gear 403. This compresses the EPDM ring 504, expelling the air and flattening it. The EPDM ring 504 then makes closer contact with the glass. The air in the central circular area of ​​the rotating gear 403 is expelled through the first solenoid valve 502 and the vacuum pump 501, making the air in the central circular area of ​​the rotating gear 403 increasingly rarefied, eventually creating a vacuum. Based on the principle of atmospheric pressure, the rotating gear 403 is then firmly adhered to the glass. Similarly, the other rotating gear will also adhere to the glass through the same operation. Because the rotating gear 403 is part of the entire machine, when both rotating gears are adhered to the glass, the machine completes the adsorption process. Figures 2-11 As shown;

[0175] It should be noted that the water spray module 8 includes: a water reservoir 801, a water pump 803, and a water spray ring 802. The water reservoir 801 and the water pump 803 are both located within the mounting cavity, with the water inlet connected to the water reservoir 801. The water spray ring 802 is located on the outside of the housing 1 and is connected to the water outlet of the water pump 803. It should be further noted that the number of water spray rings 802, water pumps 803, and water reservoirs 801 corresponds. The water spray rings 802 are symmetrically arranged on two sides of the housing 1. The water spray rings 802 are semi-circular and have several micro-outlet holes, allowing water to be sprayed out in a fan-shaped mist, increasing the spray area. Figure 27 and Figure 28 and Figure 29 As shown;

[0176] Control module 6, which is located in the installation cavity, is electrically connected to telescopic module 2, lifting module 3, rotating module 4, water spraying module 8 and adsorption module 5 respectively.

[0177] It should be noted that control module 6 has a modular structure, including:

[0178] Circuit board 601, wherein circuit board 601 is disposed within the mounting cavity;

[0179] The detection unit consists of a pressure sensor, a distance sensor, and an angle sensor. The detection unit is respectively installed on the lifting module 3, the telescopic module 2, the rotating module 4, and the adsorption module 5. The detection unit obtains the longitudinal movement parameters of the lifting module 3, the lateral movement parameters of the telescopic module 2, the rotation parameters of the rotating module 4, and the internal gas pressure value of the EPDM ring 504.

[0180] The main control chip 602 is located on the circuit board 601 and is electrically connected to the detection unit. It receives the signals collected by the detection unit and then generates action commands.

[0181] A driver chip 603 is mounted on a circuit board 601 and is electrically connected to the main control chip 602. It is also electrically connected to the first motor 203, the second motor, the third motor 404, the first solenoid valve 502, the second solenoid valve 503, and the vacuum pump 501. The driver chip 603 receives action commands from the main control chip 602 and issues them to each component. A battery module 604 is a rechargeable battery and is located within the mounting cavity.

[0182] A step-down chip 605 is disposed on a circuit board 601. It is electrically connected to the battery module 604 and the main control chip 602. It adjusts the voltage provided by the battery module 604 to supply power to the main control chip 602 and various components.

[0183] It should be noted that, in order to achieve remote control, a support frame 9 is provided inside the mounting cavity, and a signal transmission unit (electrically connected to the main control chip 602) is installed on the support frame 9. The signal transmission unit is also located on the lifting plate 301. The signal transmission unit can use infrared transmission and Bluetooth transmission to send commands to the main control chip 602 remotely, thereby changing the action. Figure 22 As shown;

[0184] The technical effects achieved by the above technical solution in the embodiments of this application are as follows:

[0185] By incorporating a telescopic module 2, a lifting module 3, a rotating module 4, and an adsorption module 5 within the housing 1, the machine achieves lateral and longitudinal movement and rotation, enabling it to overcome obstacles. The use of a dual-airflow adsorption module 5, coupled with EPDM 504 coils, enhances the adsorption effect, thereby improving overall operational stability. A water spray module is used to spray water onto the glass.

[0186] Example 2

[0187] The embodiment of this application adopts the above technical solution, which further includes: a wiping module 7, which is disposed at the bottom of the mounting cavity and is connected to the lifting plate 301 through a connecting post 702, such as Figure 20 As shown, the wiping module 7 includes:

[0188] The connecting column 702 is symmetrically arranged on the lifting plate 301 and is fixedly connected to the lifting plate 301. Its bottom extends through the lifting plate 301.

[0189] Wiping plate 701 is located below lifting plate 301 and at the bottom of lifting plate 301. It is slidably connected to connecting column 702.

[0190] Spring 703, which is sleeved on connecting post 702, with one end connected to wiping plate 701 and the other end connected to lifting plate 301;

[0191] It should be noted that the wiping plate 701 has a rectangular hole of the same shape and size as the rectangular hole on the lifting plate 301. The rotating module 4 and the adsorption module 5 are located in the two rectangular holes (in other words, the rotating module 4 and the adsorption module 5 are both inside the rectangular holes of the lifting plate 301 and the wiping plate 701, and the rotating module 4 and the adsorption module 5 can move longitudinally within the rectangular holes). The bottom of the wiping plate 701 is provided with a wiping component 706, which is detachable. The outside of the wiping plate 701 is provided with a sensor 705 and a bumper strip 704. The pressure sensor 705 detects the moving distance of the wiping plate 701, thereby avoiding the problem of the wiping plate 701 colliding due to excessive extension and retraction.

[0192] The technical effects achieved by the above technical solution in the embodiments of this application are as follows:

[0193] By adding a wiping module 7, and having the wiping module 7 work in conjunction with the adsorption module 5 and the rotation module 4 to rotate, multi-angle wiping without dead angles can be completed. At the same time, the lifting module 3 and the telescopic module 2 can be used to achieve cross-window frame operation, thereby improving work efficiency.

[0194] Example 3

[0195] The embodiments of this application employ the above-described technical solution, which further includes: a security module, wherein the security module has a combined structure, such as... Figure 23 As shown, it includes:

[0196] The rotating component 10 has a U-shaped block structure. The rotating component 10 is located in the mounting cavity and is fixedly connected to the housing 1.

[0197] The charging pile 11 is mounted on the rotating part 10 and is rotatably connected to the rotating part 10. It is also electrically connected to the battery module 604, meaning that the charging pile 11 can rotate on the rotating part 10.

[0198] Safety rope 12, one end of which is connected to charging pile 11, and the other end passes through housing 1 and is connected to locking device 14.

[0199] It should be noted that charging pile 11 has a modular structure, including:

[0200] Hollow tube 1101, one end of which is rotatably connected to rotating component 10, and has a cavity inside;

[0201] The conductive ring 1102 is disposed in the cavity and can rotate 360° in the cavity. It is electrically connected to the battery module 604. That is, the conductive ring 1102 is connected to the battery module 604 through a wire, and the wire passes through the bottom of the central control tube.

[0202] A rotating ring 1103 is sleeved on the other end of a hollow tube 1101 and is slidably connected to the hollow tube 1101. A safety rope 12 is provided on the rotating ring 1103 and is electrically connected to a conductive ring 1102.

[0203] It should be noted that safety rope 12 has a modular structure, such as... Figure 24 As shown, it includes:

[0204] Elastic outer garment 1201, wherein the elastic outer garment 1201 has a hollow channel inside;

[0205] The power cord 1202 is arranged in a corrugated shape in the hollow channel, and one end of it is electrically connected to the charging pile 11.

[0206] It should be noted that the locking device 14 is a modular structure, such as... Figure 25 and Figure 26 As shown, it includes:

[0207] The box body 1401 has a first chamber, a second chamber and a third chamber inside;

[0208] A central shaft 1402 is disposed inside the housing 1401, passing through the first chamber, the second chamber and the third chamber respectively, and is rotatably connected to the housing 1401;

[0209] Eccentric wheel 1403 is located in the first chamber and is fixedly connected to the central shaft 1402. It is provided with a swing groove and a fixed groove.

[0210] The center component 1404 is disposed in the first chamber and is fixedly connected to the central shaft 1402. One end of the center component 1404 is fitted into the fixed groove and the other end is located in the swing groove.

[0211] An internal gear 1405 is located in the first cavity and is fixedly connected to the housing 1401.

[0212] A helical spring 1406 is sleeved in the second chamber and is sleeved on the central shaft 1402. One end of the helical spring is fixedly connected to the central shaft 1402, and the other end is connected to the box body 1401.

[0213] The third chamber is equipped with a safety rope 12, which is wound around the central shaft 1402. One end of the safety rope 12 passes through the box body 1401 and the other end is fixedly connected to the electrical connection end on the third chamber.

[0214] The technical effects achieved by the above technical solution in the embodiments of this application are as follows:

[0215] During the machine's descent, the safety rope 12, under the action of the helical spring 1406, will retract into the safety rope 12 box. When the machine and the safety rope 12 box are on the same horizontal plane, the distance between them is the shortest. As the machine continues to fall from this point, because it is in free fall, its speed is very high. At this time, the central shaft 1402 drives the eccentric wheel 1403 to rotate very quickly, exceeding the normal pull-out speed. The eccentric wheel 1403 and the center component 1404 no longer make circular motion around the center shaft 1402. The eccentric wheel 1403 will move towards the internal gear 1405, and the teeth of the internal gear 1405 and the eccentric wheel 1403 will mesh together. Since the center component 1404, the center shaft 1402 and the eccentric wheel 1403 are integrated, when the eccentric wheel 1403 and the internal gear 1405 mesh together, the safety rope 12 will stop moving along with the center component 1404, the center shaft 1402 and the eccentric wheel 1403. The safety rope 12 is an elastic rope. When the central shaft 1402 stops rotating, the machine, due to its own weight, acceleration, and downward force, will stretch the safety rope 12 due to its elasticity. When it reaches its limit, the tension and the downward force of the machine act as a reaction force, causing the machine to slowly stop. This is much less destructive than directly stopping the machine from moving downwards, thus preventing internal damage and protecting the machine. The other end of the safety rope 12 is connected to a loop, which fits into the groove at the top of the power charging post. When the machine rotates, the loop prevents the safety rope 12 from tangling around the machine. Furthermore, since the power cord 1202 and the safety rope 12 are integrated, appearing as a single wire, this prevents the two wires from getting tangled.

[0216] Example 4

[0217] The technical solution described above is adopted in the embodiments of this application, and its specific working principle is as follows:

[0218] The first solenoid valve 502, the second solenoid valve 503, the first motor 203, the second motor, and the third motor 404 are each connected to different I / O ports on one end of the driver chip 603. On the other end of the driver chip 603, there is another row of corresponding I / O ports, which are connected to different I / O ports on the main control chip 602. When programming, the program is written based on the wires connected to the different I / O ports on the main control chip 602. The positive and negative terminals of the battery module 604 (main power supply) are connected to the corresponding terminals on the driver chip 603 via a switch. The main control chip 602 obtains a 5-volt operating voltage after the power module passes through the switch and is stepped down by the step-down chip 605.

[0219] When the main control chip 602 does not send a command to the terminal on the drive chip 603 connected to the first solenoid valve 502, the first air passage 4021 is connected to the outside world through the first solenoid valve 502, not to the vacuum pump 501. At this time, the vacuum pump 501 and the first air passage 4021 are disconnected and cannot circulate air. When a command is sent to the terminal on the drive chip 603 connected to the first solenoid valve 502, the first air passage 4021 is connected to the vacuum pump 501 through the first solenoid valve 502. At this time, the first air passage 4021 is no longer connected to the outside world through the first solenoid valve 502; it is now isolated from the outside world. Similarly, the connection relationship between the second solenoid valve 503, the EPDM coil 504, and the first air passage 4021 is as described above.

[0220] When the machine is placed on the glass, the EPDM ring 504, fixed to the groove of the rotating gear 403, isolates the middle part of the rotating gear 403 from the outside air. After the power switch is turned on, the voltage is stepped down to 5 volts by the step-down chip 605, and the 5 volt power supply begins to supply power to the main control chip 602. When the main control chip 602 sends an action command (0.1 or 1.0) to the drive chip 603 group, this command is sent to the terminal on the drive chip 603 group connected to the second solenoid valve 503. At this time, the second solenoid valve 503 changes from a normally closed state to a conducting state. Because the second solenoid valve 503 is connected to the first air passage 4021, the direct air pump 501 begins to inflate the EPDM ring 504. After inflating is complete, the main control chip 602 sends a new... When the action command (0.1 or 1.0) is received, this command is sent to the terminal on the drive chip 603 group connected to the first solenoid valve 502. At this time, the first solenoid valve 502 changes from a normally closed state to a conducting state. Because the first solenoid valve 502 is connected to the second air passage 4022, the vacuum pump 501 begins to draw in the air between the EPDM rings 504, creating a near-vacuum environment inside the rotating gear 403. Under the action of atmospheric pressure, and in conjunction with the EPDM rings 504, an adsorption action is formed, such as... Figure 31 As shown;

[0221] When wiping, (hereinafter referred to as the first adsorption end and the second adsorption end) the main control chip 602 sends an action command to the drive chip 603, causing the second motor of the first adsorption end to move, causing the corresponding rotating module 4 and adsorption module 5 to rise. The adsorption module 5 of the second adsorption end is in close contact with the surface of the object being wiped. By rotating the second adsorption end rotating module 4, the wiping module 7 of the first adsorption end cleans the surface of the object being wiped.

[0222] This module solves the problem of the machine slipping and falling off the glass. In existing products on the market, because a wiping cloth is used to contact the glass, and the cloth acts as a medium to isolate the suction cup from the outside air, the cloth's permeability makes it impossible to create a near-vacuum negative pressure inside the suction cup. Even with a high-flow-rate vacuum pump, this near-vacuum negative pressure cannot be achieved, leading to slippage and detachment. Furthermore, the high flow rate results in louder vacuum pump noise, explaining the machine's 70-decibel noise level. This machine, however, uses EPDM 504 rubber rings as the material to isolate the suction cup from the outside environment. Because EPDM 504 is an airtight and flexible material, when the vacuum pump 501 draws air from inside the rotating gear 403, a near-vacuum negative pressure can be created inside the gear 403—a feat unmatched by existing products on the market.

[0223] When both adsorption modules 5 are attached to the glass (hereinafter referred to as the first adsorption end and the second adsorption end), the main control chip 602 sends a command (1.1 or 0.0) to the drive chip 603. This command is sent to the terminal on one of the drive chips 603 that is connected to the first solenoid valve 502. When the first solenoid valve 502 of the first adsorption end receives this command, the first solenoid valve 502 is no longer connected to the vacuum pump 501, but is connected to the outside air. At this time, since the inside of the rotating gear 403 is now under negative pressure, outside air enters the inside of the rotating gear 403 through the first solenoid valve 502, and the inside of the rotating gear 403 is no longer under negative pressure. In the first state, the adsorption module 5 cannot adhere to the glass. Next, the main control chip 602 sends a command (1.0 or 0.1) to the drive chip 603. This command is sent to the terminal (first adsorption terminal) on the drive chip 603 connected to the second solenoid valve 503. At this time, the second solenoid valve 503 connected to the vacuum pump 501 begins to conduct with the EPDM ring 504. The vacuum pump 501 then begins to draw air from inside the EPDM ring 504 tube. At this time, the EPDM ring 504 begins to deform, no longer round, but flat. The advantage of this is that when the EPDM ring 504 becomes flat, the contact area with the glass is reduced, thus reducing friction with the glass. Next, when the main control chip 602 sends instruction 1.0 to the drive chip 603, this instruction is sent to the port on the drive chip 603 connected to the third motor 404 on the other side (the second adsorption end). At this time, the third motor 404 starts to drive the gear to rotate. Because the adsorption module 5 of the second adsorption end is attached to the glass, when the third motor 404 rotates, the machine rotates around the adsorption module 5 that is in close contact with the glass. When the main control chip 602 sends instruction 0.1 to the drive chip 603, this instruction is sent to the port on the drive chip 603 connected to the third motor 404 at the close contact end. At this time, the third motor 404 starts to drive the gear to rotate. Because the gear on the third motor meshes with the rotating gear 403, and because the adsorption module 5 of the second adsorption end is attached to the glass, when the third motor 404 rotates, the machine rotates in the opposite direction around the adsorption module 5 of the second adsorption end. When the main control chip 602 sends a command (1.1 or 0.0) to the drive chip 603, this command is sent to the port on the drive chip 603 connected to the third motor 404. At this time, the drive chip 603 no longer supplies power to the third motor 404, and the machine stops in place, waiting for the next command to execute the next step of work. The function of the universal ball 405 is to prevent the machine from wobbling when rotating due to bearing clearance. The universal ball 405 also prevents wobbling because it contains a steel ball that rotates on the rotating gear 403. Since the steel ball rotates rather than linearly, it maintains the horizontal movement of the machine while the universal ball 405 rotates, reducing unnecessary resistance caused by friction. Figure 42 As shown in step 1;

[0224] When both adsorption ends (hereinafter referred to as the first adsorption end and the second adsorption end) are adsorbed onto the glass, the main control chip 602 sends a command (0.1) to the drive chip 603. This command is sent to the wiring port on the drive chip 603 that is connected to the first solenoid valve 502. After the drive chip 603 receives this command, it causes the first solenoid valve 502 in the first adsorption end to no longer be connected to the vacuum pump 501, but instead to be connected to the outside air through the first solenoid valve 502. Because the rotating gear 403 of the first adsorption end is under negative pressure at this time, according to the principle of atmospheric pressure, the outside air will enter the rotating gear 403 through the first solenoid valve 502. In step 3, the rotating gear 403 at the first adsorption end is no longer under negative pressure, so the first adsorption end cannot adhere to the glass; only the second adsorption end remains attached. Next, the main control chip 602 sends a command (1.0) to the drive chip 603. This command is sent to the port on the drive chip 603 connected to the second motor at the first adsorption end. Upon receiving this command, the second motor begins to rotate forward. Because the second motor meshes with the second rack 303, which is fixed to the base plate 401 in the rotating module 4, the machine is raised as a whole when the second motor rotates forward. Similarly, when the main control chip 602 sends a command (1.0) to the drive chip 603, the second motor rotates in the reverse direction, causing the machine to descend. When the main control chip 602 sends a command (1.1 or 0.0) to the drive chip 603, the drive chip 603 connected to the second motor stops supplying power, and the machine maintains its previous state. Figure 32 As shown;

[0225] When both adsorption modules 5 are attached to the glass (hereinafter referred to as the first adsorption end and the second adsorption end), the main control chip 602 sends a command (1.1 or 0.0) to the drive chip 603. This command is sent to the terminal on the drive chip 603 connected to the first solenoid valve 502 (the first adsorption end). When the first solenoid valve 502 receives this command, it is no longer connected to the vacuum pump 501, but to the outside air. At this time, the rotating gear 403 at the first adsorption end is now under negative pressure. Outside air enters the rotating gear 403 through the first solenoid valve 502. At this time, the rotating gear 403 at the first adsorption end is no longer under negative pressure. The adsorption end cannot adhere to the glass; only the second adsorption end adheres to the glass. Next, the main control chip 602 sends a command (1.0 or 0.1) to the drive chip 603. This command is sent to the terminal (in the first adsorption end) on the drive chip 603 connected to the second solenoid valve 503. At this time, the second solenoid valve 503 connected to the vacuum pump 501 begins to conduct with the EPDM ring 504. The vacuum pump 501 then begins to draw air from inside the EPDM ring 504 tube. At this time, the EPDM ring 504 begins to deform, no longer round, but flat. The advantage of this is that when the EPDM ring 504 becomes flat, the contact area with the glass is reduced, thus reducing friction with the glass. Next, the main control chip 602 sends a command (1.0) to the drive chip 603. This command is sent to the terminal on the drive chip 603 connected to the motor on the telescopic module 2 (the first adsorption end). When the drive chip 603 receives this command, the first motor 203 is powered on and begins to rotate forward. Because the first rack 204 is fixed to the lifting plate 301, and the lifting plate 301 is fixed to the second slider 3031 and the second optical axis 302, and the lifting plate 301 is also fixed to the adsorption module 5 (the second adsorption end), the adsorption module 5 (the second adsorption end) is adsorbed onto the glass, while the adsorption module 5 (the first adsorption end) is not adsorbed onto the glass. The first motor 203 is fixed to the lifting plate 301. Thus, through the second slider, the second optical axis 302, and the second rack 303, the adsorption module 5 on the first adsorption end is pushed out. Similarly, when it is necessary to reset or pull back the adsorption module 5 on the first adsorption end, the direction of the second motor 3001 can be reversed. When the main control chip 602 sends a command (1.1 or 0.0) to the drive chip 603, this command is sent to the terminal on the drive chip 603 that is connected to the second motor on the first adsorption end. Upon receiving this command, the drive chip 603 de-energizes the second motor, stops rotating, and the machine maintains its current state. Figure 43 As shown in step 5;

[0226] When the main control chip 602 sends a command (1.0) to the drive chip 603, this command is sent to the port on the drive chip 603 connected to the water pump 803. At this time, the water pump 803 is powered on and begins to draw water from the water tank 801. The water is then transferred to the spray ring 802 by the water pump 803. Because there are micro-holes on the spray ring 802, the water is sprayed out from the micro-holes due to the water pressure. At the same time, because the holes on the spray ring 802 are arranged in different directions, the sprayed water is in a fan shape, so that the water can spray one side of the machine. When the main control chip 602 sends a command (1.1 or 0.0) to the drive chip 603, this command is sent to the port on the drive chip 603 connected to the water pump 803. At this time, the drive chip 603 no longer supplies power to the water pump 803, and the spray ring 802 does not spray water outward. When programming, the system determines when to spray water based on the machine's different operating states. In each state, code is written to instruct the machine to spray water. When the machine reaches the state where water spraying is required, the main control chip 602 sends a command to the driver chip 603. The driver chip 603 then activates the water spraying device based on the received command, and water is sprayed outwards from the water reservoir 801 through the spray ring 802. Figure 27 and Figure 28 and Figure 29 As shown;

[0227] This section describes the machine's actions during operation, including adsorption, rotation, extension, lifting, wiping, and water spraying. The examples above provide a clear understanding of the machine's actual working state. It should be noted that programming is a known technology in this field, and therefore will not be elaborated upon further.

[0228] Example 5

[0229] The technical solution described above is adopted in the embodiments of this application, and its specific working principle is as follows:

[0230] When the machine is rotating or wiping, the angle sensor group 15 determines its operating status by which sensor the pointer aligns with. The angle sensor group 15 has four sensors distributed in the four directions (up, down, left, and right) of the central rotating pointer. When the machine is working on the window glass, the rotating pointer is always perpendicular to the ground. When the machine rotates, one of the four sensors aligns with the rotating pointer. When this sensor aligns, it sends a signal to the main control chip 602. The main control chip 602 determines the machine's direction and position based on the signal from the angle sensor, and then sends the next correct instruction for the machine to execute. Figure 22 As shown;

[0231] Each sensor in the angle sensor group has three wires: a power supply wire (positive and negative) and a signal wire. The power supply wire is connected to the positive and negative terminals of the main control chip 602 for external power supply, and the signal wire is connected to the I / O port of the main control chip 602. The other sensors have two wires, with no distinguishing between positive and negative terminals. One wire is connected to the negative terminal of the main control chip 602 for external power supply, and the other wire is connected to the I / O port of the main control chip 602.

[0232] The technical effects achieved by the above technical solution in the embodiments of this application are as follows:

[0233] This utility model provides a fully automatic window cleaning machine that can operate across window frames, optimizing and solving the following problems encountered by similar products in actual operation:

[0234] 1. Problems with the machine slipping and falling due to lack of grip;

[0235] 2. The problem of excessive noise;

[0236] 3. The problem of not being able to wipe the four corners of the window;

[0237] 4. The problem of the machine not being damaged when it is accidentally dropped.

[0238] 5. The problem of low work efficiency.

[0239] 6. Uneven water spraying problem.

[0240] 7. The problem of not being able to automatically move from one window to another across the window frame.

[0241] Existing products on the market all encounter the seven problems mentioned above in actual operation, but none of them can perfectly solve these seven problems. This product completely solves these seven problems technically, ensuring that the glass cleaning machine will not slip or fall off regardless of the amount of dirt or moisture on the glass surface. Similar products are quite noisy, generally around 70 decibels, while this product is only around 50 decibels, making it much quieter. Due to design flaws, similar products cannot reach the four corners of the glass when cleaning, which is a drawback. This product has a more reasonable design. The machine can wipe all four corners, which is a significant improvement and breakthrough. Most importantly, it can move from one window sash to another to work, a feature not found in similar products and a completely new function. Unlike similar products where the spray can't cover the entire surface, this product solves this problem with its spray ring 802. Furthermore, the safety rope 12 in similar products doesn't consider cushioning, so if the machine falls, it will generate a strong, direct pulling force without any cushioning, potentially damaging the internal structure. This product incorporates cushioning in its design, providing protection should the machine fall.
