Description

Technical Field

[0001] This utility model relates to the field of glass cleaning machines, and in particular to a fully automatic glass cleaning machine. Background Technology

[0002] As people's living standards improve and urban buildings rise, more and more people live in high-rise buildings, making high-rise window cleaning a very dangerous task. Cleaning indoor windows is relatively easy and less dangerous, but cleaning outdoor windows is quite dangerous. A person has to lean forward and stick their upper body out of the window while holding window cleaning tools, which is very strenuous and dangerous, and the glass 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.

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

[0017] 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.

[0018] Therefore, there is an urgent need for a fully automatic window cleaning machine that can solve the above problems. Utility Model Content

The removable wiping cloth plate comes in two types: a regular flat plate and a textured surface with many raised particles. A regular flat plate can wipe away loose dust and stains on the glass. However, if there are stains firmly adhered to the glass, a regular flat plate is not effective at removing them. The textured surface of the wiping plate, with its raised points, provides more pressure points than a flat surface. Based on the principle of pressure, each point on this textured surface exerts a greater force, thus dividing the stain into smaller parts and further segmenting it. This makes it easier to remove stubborn stains and dust from the glass than a flat plate. The removable wiping plate is fixed to the wiping plate base plate, and the wiping cloth is located on the removable wiping plate.

[0071] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0072] The purpose of this invention is to provide a fully automatic glass cleaning machine to solve the problems existing in the prior art.

[0073] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0074] Example 1:

[0075] This embodiment provides a fully automatic window cleaning machine, such as Figure 1-34 As shown, it includes an adsorption module, a rotation module, a lifting module, a telescopic module, an angle sensor module, an infrared transmitter and receiver module, a water spray module, a central processing unit system module, a power supply system module, a handle module, a wiping plate module, and a safety module.

[0076] The machine's adsorption module has two suction cups, both of which need to be attached to the glass when the machine starts working. The first vacuum pump 10 and the second vacuum pump 36 are connected to the power switch; when the switch is on, both vacuum pumps begin to operate. The first solenoid valve 12, the second solenoid valve 13, the third solenoid valve 33, and the fourth solenoid valve 34 are open to the outside air when not powered; they only connect to the first gear suction cup 48, the second gear suction cup 58, or the first EPDM ring 49 and the second EPDM ring 57 when powered on.

[0077] Specifically, the adsorption module includes: a first telescopic rod assembly 1, a power charging column 2, a first sensor 4, a first base plate 8, a first vacuum pump 10, a first solenoid valve 12, a second solenoid valve 13, a first rotating shaft assembly 14, a first bearing 15, a battery 17, a drive chip 18, a power switch 22, a main control chip 25, a second bearing 31, a second rotating shaft assembly 32, a third solenoid valve 33, a fourth solenoid valve 34, a second vacuum pump 36, a second base plate 40, a sixth sensor 41, a second telescopic rod assembly 44, a third wiping cloth plate 47, a first gear suction cup 48, a first EPDM ring 49, a second gear suction cup 58, a second EPDM ring 57, and a fourth wiping cloth plate 59.

[0078] When the power switch is turned on, the first vacuum pump 10 and the second vacuum pump 36 start to draw air. When the main control chip 25 sends a command (0.1 or 1.0) to the drive chip 18, this command is sent to the terminal on the drive chip 18 connected to the first solenoid valve 12 and the third solenoid valve 33. When the first solenoid valve 12 and the third solenoid valve 33 receive the above command, the first solenoid valve 12 and the third solenoid valve 33 start to conduct with the first vacuum pump 10 and the second vacuum pump 36. At this time, the first vacuum pump 10 and the second vacuum pump 36 begin to suck air from the first gear suction cup 48 and the second gear suction cup 58 through the sealing ring 82 on the first rotating shaft assembly 14 and the second rotating shaft assembly. When the machine is placed on the glass, because there is air inside the first EPDM ring 49 and the second EPDM ring 57, the first EPDM ring 49 and the second EPDM ring 57 remain in their original shape, that is, they are circular. The third wiping cloth plate 47 and the fourth wiping cloth plate 59 are not as high as the first EPDM ring 49 and the second EPDM ring 57. Thus, the first EPDM ring 49, The second EPDM ring 57 is pressed together with the glass. Because the first EPDM ring 49 and the second EPDM ring 57 act as a medium, the air inside the first gear suction cup 48 and the second gear suction cup 58 is isolated from the outside air, meaning they are not connected. When the first vacuum pump 10 and the second vacuum pump 36 pass through the first solenoid valve 12 and the third solenoid valve 33, and then through the sealing ring 82 on the first rotating shaft assembly 14 and the second rotating shaft assembly 32, which communicates with the first gear suction cup 48 and the second gear suction cup 58, they begin to suction the first gear suction cup 48 and the second gear suction cup 58. When the air inside the first gear suction cup 48 and the second gear suction cup 58 becomes increasingly scarce, the negative pressure increases, approaching a vacuum. At this time, the first gear suction cup 48 and the second gear suction cup 58 begin to move closer to the glass. Simultaneously, when the main control chip 25 does not send instructions (1.0 or 0.1) to the drive chip, the second solenoid valve 13 and the fourth solenoid valve 34 connected to the first EPDM ring 49 and the second EPDM ring 57 are open to the outside air. When the air inside the wheel suction cup 48 and the second gear suction cup 58 is almost non-existent, and is close to a vacuum, the air inside the first EPDM ring 49 and the second EPDM ring 57 is squeezed out through the sealing ring 82 on the first rotating shaft assembly 14 and the second rotating shaft assembly 32, which communicates with the second solenoid valve 13 and the fourth solenoid valve 34. The first EPDM ring 49 and the second EPDM ring 57 are tightly pressed together with the glass. At this time, the air inside the first gear suction cup 48 and the second gear suction cup 58 is in a vacuum state, and the first gear suction cup 48 and the second gear suction cup 58 are tightly attracted to the glass.Because the first gear suction cup 48 and the second gear suction cup 58 are part of the machine, the first gear suction cup 48, the second gear suction cup 58, the first rotating shaft assembly 14, and the second rotating shaft assembly 32 are fixed together. The first rotating shaft assembly 14 and the second rotating shaft assembly 32 are fixed together with the first base plate 8 and the second base plate 40 of the machine through the first bearing 15 and the second bearing 31. In this way, the entire machine is suctioned to the glass. Because the wiping plate 47 and the fourth wiping cloth plate 59 are connected to the first base plate 8 and 40 of the machine through the first telescopic rod assembly 1 and 44, and a first spring is added between the first telescopic rod assembly 1, the second telescopic rod assembly 44 and the first base plate 8 and the second base plate 40, when the first gear suction cup 48 and the second gear suction cup 58 are attached to the glass, the first EPDM ring 49 and the second EPDM ring 57 are squeezed. At this time, the third wiping cloth plate 47 and the fourth wiping cloth plate 59 protrude slightly from the first gear suction cup 48 and the second gear suction cup 58. Because of the first spring, the third wiping cloth plate 47 and the fourth wiping cloth plate 59 are passively flush with the first gear suction cup 48 and the second gear suction cup 58. At this time, the third wiping cloth plate 47 and the fourth wiping cloth plate 59 are also squeezed together with the glass. The function of the first spring is to extend and retract. The first rotating shaft assembly 14 and the second rotating shaft assembly 32 each have two sealing rings 82, one communicating with the corresponding gear chuck and the other with the corresponding EPDM ring. The first gear chuck 48 is connected to the first solenoid valve 12, the second gear chuck 58 is connected to the third solenoid valve 33, the first EPDM ring 49 is connected to the second solenoid valve 13, and the second EPDM ring 57 is connected to the fourth solenoid valve 34. The first solenoid valve 12, the second solenoid valve 13 are connected to the first vacuum pump 10, and the third solenoid valve 33, the fourth solenoid valve 34 are connected to the second vacuum pump 36. The first solenoid valve 12, the second solenoid valve 13, the third solenoid valve 33, and the fourth solenoid valve 34 are two-position three-way solenoid valves. When connecting the pipeline, the pipeline is connected according to the principle that when the solenoid valve is not energized, it is connected to the outside air, and when energized, it is connected to the vacuum pump. Since the first EPDM ring 49, the second EPDM ring 57, the first gear suction cup 48, and the second gear suction cup 58 all require the first vacuum pump 10 and the second vacuum pump 36 for air intake, the design of the pipeline connection method can reduce the number of vacuum pumps required while still achieving the intended purpose.The first sensor 4 and the sixth sensor 41 are placed under the first base plate 8 and the second base plate 40. Their function is that when the air in the first gear suction cup 48 and the second gear suction cup 58 is sucked away by the first vacuum pump 10 and the second vacuum pump 36, the third wiping cloth plate 47 and the fourth wiping cloth plate 59 will retract towards the first base plate 8 and the second base plate 40 after being squeezed by the glass. When the first sensor 4 and the sixth sensor 41 send a signal to the main control chip 25, it indicates that the first gear suction cup 48 and the second gear suction cup 58 have been attracted to the glass, and the main control chip 25 can send the next working instruction. If the air inside the first gear suction cup 48 and the second gear suction cup 58 is not completely sucked out during the suction process of the first vacuum pump 10 and the second vacuum pump 36, and the first gear suction cup 48 and the second gear suction cup 58 are not completely adhered to the glass, then the third wiping cloth plate 47 and the fourth wiping cloth plate 59 will not retract to the distance where the sensor can send a signal to the main control chip 25 due to the pressure of the glass. At this time, the first sensor 4 and the sixth sensor 41 will not send a signal to the main control chip 25. Only when the first gear suction cup 48 and the second gear suction cup 58 are completely adhered to the glass will the first sensor 4 and the sixth sensor 41 send a signal to the main control chip 25. After receiving the signals from both, the main control chip 25 will send the next working instruction; otherwise, the main control chip 25 will not send the next instruction. When the machine is lifting, extending, or rotating, one of its two suction cups is attached to the glass while the other is not. If both suction cups are attached, the machine cannot perform these actions. Under normal operating conditions, with one suction cup attached and the other not, after a work command is completed, both suction cups must be simultaneously attached to the glass again. The main control chip 25 then sends commands based on the machine's current operating status, instructing which suction cup to be attached and which to be deattached, so that the machine can proceed to the next step. In other words, during operation, a command for both suction cups to be simultaneously attached to the glass must be added between two different commands. This is accomplished through programming.

[0079] 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 vacuum pump, a near-vacuum negative pressure cannot be achieved. Furthermore, the high flow rate results in a louder vacuum pump, which explains the machine's slipping and falling, and the 70-decibel noise level. This machine, however, uses EPDM (ethylene propylene diene monomer) rings as the material to isolate the suction cup from the outside air. Because EPDM is an airtight material, the vacuum pump can create a near-vacuum negative pressure inside the suction cup when sucking in air—something existing products on the market cannot achieve. Simultaneously, the solenoid valve and two sealing rings 82 on the rotating shaft assembly are connected to the vacuum pump. The sealing rings 82 are aluminum alloy rings with two grooves for housing sealing rings 83—a feature not found in other products on the market. The rotating shaft assembly, along with its two sealing rings (82) and EPDM rings, were all designed and developed in-house and manufactured by a factory; there are no similar products on the market. Because the vacuum pump uses a miniature pump with a small flow rate, it is correspondingly quieter.

[0080] Furthermore, the rotating module includes: a power charging column 2, a first base plate 8, a first vacuum pump 10, a first solenoid valve 12, a second solenoid valve 13, a first rotating shaft assembly 14, a first bearing 15, a second motor 16, a battery 17, a drive chip 18, a main control chip 25, a rotating pointer 28, a third motor 29, an angle sensor group 30, a second bearing 31, a second rotating shaft assembly 32, a third solenoid valve 33, a fourth solenoid valve 34, a second vacuum pump 36, a second base plate 40, a seventh sensor 46, a third wiping cloth plate 47, a first gear suction cup 48, a first EPDM ring 49, a first gear 51, a second gear 56, a second gear suction cup 58, a fourth wiping cloth plate 59, and an eighth sensor 60.

[0081] When both suction cups are attached to the glass, the main control chip 25 sends a command (0.0 or 1.1) to the drive chip 18. This command is sent to the terminal on the drive chip 18 that is connected to the first solenoid valve 12. When the first solenoid valve 12 receives this command, it is no longer connected to the first vacuum pump 10, but is connected to the outside air. Because the inside of the first gear suction cup 48 is now under negative pressure, the outside air enters the first gear suction cup 48 through the first solenoid valve 12 and then through the sealing ring 82 on the first rotating shaft assembly 14 that is connected to the first gear suction cup 48. At this time, the inside of the first gear suction cup 48 is no longer a vacuum and there is no negative pressure. At this time, the first gear suction cup 48 is no longer attached to the glass. After the machine executes this instruction, the main control chip 25 sends another instruction (1.0 or 0.1) to the drive chip 18. This instruction is sent to the terminal on the drive chip 18 that is connected to the second solenoid valve 13. When the second solenoid valve 13 receives this instruction, it is no longer connected to the outside air, but to the first vacuum pump 10. At this time, the first vacuum pump 10 draws air from inside the first EPDM ring 49 through the second solenoid valve 13 and then through the sealing ring 82 on the first rotating shaft assembly 14 that is connected to the first EPDM ring 49. Because the first EPDM ring 49 is currently pressed against the glass, if the machine is rotated at this time, there will be friction between the first EPDM ring 49 and the glass, which will generate resistance and damage the surface of the first EPDM ring 49. To avoid this situation, the air inside the first EPDM ring 49 is sucked out before the machine rotates. When the inside is close to a vacuum, the first EPDM ring 49 has been flattened. At this time, the first EPDM ring 49 is no longer in contact with the glass. At the same time, the third wiping cloth plate 47 is still pressed against the glass. After the first vacuum pump 10 completes its action of sucking air from the first EPDM coil 49, the main control chip 25 sends another instruction (1.0 or 0.1) to the drive chip 18. This instruction is sent to the terminal on the drive chip 18 that is connected to the third motor 29. After receiving this instruction, the drive chip 18 starts to supply power to the third motor 29. After receiving power, the third motor 29 starts to drive the second gear 56 to rotate. (The instruction sent by the main control chip 25 is (1.0 or 0.1). If the instruction is (1.0), the third motor 29 rotates forward. If the instruction is (0.1), the third motor 29 rotates in reverse. This is related to how the wiring is done.)When the third motor 29 drives the second gear 56 to rotate, the teeth on the edge of the second gear 56 and the second gear suction cup 58 mesh together, causing the second gear suction cup 58 to be tightly adhered to the glass. The second gear suction cup 58 is fixed to the second rotating shaft assembly 32, on which a second bearing 31 is mounted. The second bearing 31 is fixed to the second base plate 40 of the machine. Because the second gear suction cup 58 is firmly adhered to the glass and remains stationary, and the third motor 29 is fixed to the second base plate 40, when the second gear 56 on the third motor 29 rotates, it will make a circular motion around the second rotating shaft assembly 32 as the axis, along the teeth on the edge of the second gear suction cup 58. If the seventh sensor 46 or the angle sensor group 30 sends a signal to the main control chip 25 during this circular motion, it indicates that the machine needs to stop its current operation and execute the next instruction. If the signal is sent from the seventh sensor 46 to the main control chip 25, it indicates that the machine has encountered an obstacle or the edge of a window. If the signal is sent from the angle sensor group 30 to the main control chip 25, the main control chip 25 will determine the machine's orientation by which specific sensor in the angle sensor group 30 sent the signal, and determine the machine's next step based on the result of the determination.When the machine's main control chip 25 receives a signal from the seventh sensor 46 or the angle sensor group 30, it sends a command (0.0 or 1.1). This command is sent to the terminal on the drive chip 18 connected to the third motor 29. When the drive chip 18 receives this command, it will no longer supply power to the third motor 29, and the third motor 29 will stop rotating. Consequently, the machine will also stop rotating. At this time, the main control chip 25 will send a command (0.0 or 1.1) to the drive chip 18. This command is sent to the terminal on the drive chip 18 connected to the second solenoid valve 13. When the second solenoid valve 1... 3. Upon receiving the above instruction, the second solenoid valve 13 is no longer connected to the first vacuum pump 10, but is connected to the outside air. Because the inside of the first EPDM ring 49 is currently under vacuum and negative pressure, when the second solenoid valve 13 is connected to the outside air, the outside air will pass through the second solenoid valve 13 and then through the sealing ring 82 on the first rotating shaft assembly 14 that communicates with the first EPDM ring 49 to enter the inside of the first EPDM ring 49. When the air enters the inside of the first EPDM ring 49, due to its elasticity, the first EPDM ring 49 will return to its original state. At this time, the first EPDM ring 49 is once again pressed against the glass. After executing this instruction, the main control chip 25 will send another instruction (1.0 or 0.1) to the driver chip 18. This instruction is sent to the terminal on the driver chip 18 that is connected to the first solenoid valve 12. When the driver chip 18 receives this instruction, the first solenoid valve 12 is no longer connected to the outside air, but is connected to the first vacuum pump 10. At this time, the first vacuum pump 10 begins to suck air from the first gear suction cup 48 through the first solenoid valve 12 and then through the sealing ring 82 on the first rotating shaft assembly 14 that is connected to the first solenoid valve 12. This is because the first EPDM ring 49 is pressed together with the glass at this time. Therefore, the air inside the first gear suction cup 48 is isolated from the outside air. During the process of the first vacuum pump 10 sucking out the air from the first gear suction cup 48, if the first sensor 4 does not send a signal to the main control chip 25, it indicates that there is still air inside the first gear suction cup 48 and it is not yet a vacuum. At this time, the first vacuum pump 10 continues to suck out the air inside the first gear suction cup 48. When the first sensor 4 sends a signal to the main control chip 25, it indicates that the inside of the first gear suction cup 48 is nearly a vacuum, and the first gear suction cup 48 has adhered to the glass. The main control chip 25 can then send instructions for the machine to proceed to the next step. When the machine is performing circular motion, if the seventh sensor 46 or the angle sensor group 30 does not send a signal to the main control chip 25, the machine will continue to perform circular motion until it receives a signal from the seventh sensor 46 or the angle sensor group 30 to stop its current operation.

[0082] Furthermore, the lifting module includes: a power charging column 2, a first wiping cloth plate 3, a first motor 5, a first rotating assembly 6, a second sensor 9, a third sensor 11, a drive chip 18, a main control chip 25, a fourth sensor 35, a fifth sensor 37, a fourth motor 39, a second rotating assembly 38, and a second wiping cloth plate 43; the power of the first wiping cloth plate 3 and the second wiping cloth plate 43 is obtained through the main shaft transmission of the first rotating assembly 6 and the second rotating assembly 38 with the first motor 5 and the fourth motor 39.

[0083] When both suction cups are attached to the glass, the main control chip 25 sends a command (0.1) to the driver chip 18. This command is sent to the terminal connected to the first motor 5 on the driver chip 18. After receiving this command, the driver chip 18 starts to supply power to the first motor 5. Because the first wiping cloth plate 3 is currently in a raised state, after the first motor 5 is powered on, it begins to rotate in the reverse direction. The first rotating component 6 and the main shaft of the first motor 5 are fixed together, and the first wiping cloth plate 3 is fixed together with the first rotating component 6. When the first motor 5 rotates in the reverse direction... When rotating, the first rotating component 6 and the first wiping cloth plate 3 also move in a circular motion around the axis of the first motor 5. When the third sensor 11 sends a signal to the main control chip 25, it indicates that the first wiping cloth plate 3 has come into contact with the glass. At this time, the main control chip 25 sends an instruction (0.0 or 1.1) to the drive chip 18. This instruction is sent to the terminal on the drive chip 18 that is connected to the first motor 5. When the drive chip 18 receives this instruction, it no longer provides power to the first motor 5. At this time, the first motor 5 stops rotating, and the machine maintains its current state. When the first wiping cloth plate 3 needs to return to its original state, the main control chip 25 sends a command (1.0). This command is sent to the terminal on the drive chip 18 connected to the first motor 5. When the drive chip 18 receives the command, it supplies power to the first motor 5. At this time, the first motor 5 rotates in the forward direction. The first rotating component 6 and the first wiping cloth plate 3 move in a circular motion around the main shaft of the first motor 5. When the second sensor 9 sends a signal to the main control chip 25, it indicates that the first wiping cloth plate 3 has returned to its initial position. At this time, the main control chip 25 sends a command (0.0 or 1.1). This command is sent to the terminal on the drive chip 18 connected to the first motor 5. When the drive chip 18 receives this command, it stops supplying power to the first motor 5, and the first motor 5 stops rotating.At this time, the main control chip 25 sends a command (0.0 or 1.1) to the driver chip 18. This command is sent to the terminal connected to the second solenoid valve 13 on the driver chip 18. After receiving the above command, the second solenoid valve 13 is no longer connected to the first vacuum pump 10, but is connected to the outside air. Because the inside of the first EPDM coil 49 is now under vacuum, when the second solenoid valve 13 is connected to the outside air, the outside air will pass through the second solenoid valve 13 and then through the first rotating shaft assembly 14 connected to the first EPDM coil 10. The sealing ring 82, which is connected to the first EPDM ring 49, enters the interior of the first EPDM ring 49. When air enters the interior of the first EPDM ring 49, due to its elasticity, the first EPDM ring 49 will return to its original state. At this time, the first EPDM ring 49 is pressed against the glass again. After this instruction is executed, the main control chip 25 will send another instruction (1.0 or 0.1) to the drive chip 18. This instruction is sent to the terminal on the drive chip 18 that is connected to the first solenoid valve 12. When the drive chip 18 receives this instruction, The first solenoid valve 12 is no longer connected to the outside air, but is connected to the first vacuum pump 10. At this time, the first vacuum pump 10 begins to draw air from the first gear suction cup 48 through the first solenoid valve 12 and then through the sealing ring 82 on the first rotating shaft assembly 14 that is connected to the first solenoid valve 12. Because the first EPDM ring 49 is pressed against the glass at this time, the air in the first gear suction cup 48 is isolated from the outside air. During the process of the first vacuum pump 10 drawing air from the first gear suction cup 48, if the first sensor 4 does not send a signal to the main control chip... When chip 25 sends a signal, it indicates that there is still air inside the first gear suction cup 48 and it is not yet a vacuum. At this time, the first vacuum pump 10 continues to suck up the air inside the first gear suction cup 48. When the first sensor 4 sends a signal to the main control chip 25, it indicates that the inside of the first gear suction cup 48 is close to a vacuum and the first gear suction cup 48 has been suctioned onto the glass. At this time, the first EPDM ring 49 and the second EPDM ring 57 of the two gear suction cups on the machine are both suctioned onto the glass, which completes the preliminary work for sending the next instruction to the main control chip 25.

[0084] like Figure 25 The diagram shows the structure of the rotating component on the lifting module. The working state of the second wiping cloth plate 43 can be adjusted by the rotating shaft 88 so that the second wiping cloth plate 43 is flat with the glass. The telescopic rod 89 can be moved backward when there is an obstacle in front, so that the seventh sensor 46 behind can send a signal to the main control chip 25.

[0085] Furthermore, the telescopic module includes a telescopic rod 19, a linear slider 24, a telescopic motor 26, a rack 27, a first sensor 4, an eighth sensor 60, a sensor group 53, a telescopic plate 54, a main control chip 25, and a drive chip 18.

[0086] When both the first gear suction cup 48 and the second gear suction cup 58 on the machine are attached to the glass, the main control chip 25 sends a command (0.0 or 1.1) to the drive chip 18. This command is sent to the terminal on the drive chip 18 connected to the first solenoid valve 12. After the drive chip 18 receives this command, the first solenoid valve 12 is no longer connected to the first vacuum pump 10, but is connected to the outside air. At this time, the outside air passes through the first solenoid valve 12, and then through the sealing ring 82 on the first rotating shaft assembly 14 that communicates with the first gear suction cup 48, and enters the first gear suction cup 48. When the air enters the first gear suction cup... After 48, the internal pressure is no longer a vacuum state. At this time, the first gear suction cup 48 no longer adheres to the glass. After executing this instruction, the main control chip 25 sends an instruction (1.0 or 0.1) to the drive chip 18. This instruction is sent to the terminal on the drive chip 18 connected to the second solenoid valve 13. When the drive chip 18 receives this instruction, the second solenoid valve 13 is no longer connected to the outside air and begins to connect to the first vacuum pump 10. At this time, the first vacuum pump 10 begins to draw the first EPDM ring 49 through the second solenoid valve 13 and then through the sealing ring 82 on the first rotating shaft assembly 14 that connects to the second solenoid valve 13. As the air inside the first EPDM ring 49 decreases, approaching a vacuum, the first EPDM ring 49 is flattened by suction, no longer pressed against the glass. After this instruction is completed, the main control chip 25 sends instruction (1.0) to the drive chip 18. This instruction is sent to the terminal on the drive chip 18 connected to the telescopic motor 26. When the drive chip 18 receives this instruction, it begins to supply power to the telescopic motor 26. At this time, the telescopic motor 26 rotates in the forward direction because the gear on the telescopic motor 26 meshes with the rack 27, which is fixed. On the first base plate 8, the telescopic motor 26 is fixed to the second base plate 40, and the second gear suction cup 58 is attached to the glass. When the telescopic motor 26 rotates, the gear on the telescopic motor 26 pushes the rack 27 forward. The rack 27 is fixed to the first base plate 8, which is also pushed forward. The telescopic rod 19 is extended and is fitted inside the linear slider 24. The function of the telescopic rod 19 and the linear slider is to keep the first base plate 8 and the second base plate 40 in a horizontal position without deformation when extending or retracting. At the same time, because the linear slider 24 has ball bearings inside, the resistance is small and the operation is smooth. When the seventh sensor 46 or the sensor group 53 sends a signal to the main control chip 25, it indicates that the machine has encountered a special situation during the forward extension process and the machine needs to stop its current working state. If the signal is sent by the seventh sensor 46 to the main control chip 25, it means that the front of the machine has touched the glass frame. If the signal is sent by the sensor group 53 to the main control chip 25, it means that the machine has reached its maximum extension value.When either of the above two situations occurs, the main control chip 25 sends a command (0.0 or 1.1) to the drive chip 18. This command is sent to the terminal on the drive chip 18 that is connected to the telescopic motor 26. When the drive chip 18 receives this command, it will disconnect the power supply to the telescopic motor 26. At this time, the telescopic motor 26 stops rotating, and the machine stops in its current state. If the machine needs to retract, the main control chip 25 will send a command (0.1) to the drive chip 18. This command is sent to the terminal on the drive chip 18 connected to the telescopic motor 26. At this time, the drive chip 18 starts to supply power to the telescopic motor 26, and the telescopic motor 26 rotates in the reverse direction. During the reverse rotation of the telescopic motor 26, if the main control chip 25 does not receive a signal from the sensor group 53, the telescopic motor 26 will continue to rotate. When the main control chip 25 receives a signal from the sensor group 53, it indicates that the machine has retracted to its initial state. At this time, the main control chip 25 sends a command (0.0 or 1.1) to the drive chip 18. This command is sent to the terminal on the drive chip 18 connected to the telescopic motor 26. When the drive chip 18 receives this command, it stops supplying power to the telescopic motor 26, and the telescopic motor 26 stops rotating, and the machine stops in its current state.Next, the main control chip 25 will send an instruction (0.0 or 1.1) to the driver chip 18. This instruction is sent to the terminal connected to the second solenoid valve 13 on the driver chip 18. After receiving the above instruction, the second solenoid valve 13 is no longer connected to the first vacuum pump 10, but is connected to the outside air. Because the first EPDM coil 49 is currently under vacuum, when the second solenoid valve 13 is connected to the outside air, the outside air will pass through the second solenoid valve 13 and then through the first rotating shaft assembly 14 connected to the first... The sealing ring 82, which is connected to the first EPDM ring 49, enters the interior of the first EPDM ring 49. When air enters the interior of the first EPDM ring 49, due to its elasticity, the first EPDM ring 49 will return to its original state. At this time, the first EPDM ring 49 is pressed against the glass again. After this instruction is executed, the main control chip 25 will send another instruction (1.0 or 0.1) to the drive chip 18. This instruction is sent to the terminal on the drive chip 18 that is connected to the first solenoid valve 12. When the drive chip 18 receives this instruction... After the command, the first solenoid valve 12 is no longer connected to the outside air, but is connected to the first vacuum pump 10. At this time, the first vacuum pump 10 begins to draw air from the first gear suction cup 48 through the first solenoid valve 12 and then through the sealing ring 82 on the first rotating shaft assembly 14 that is connected to the first solenoid valve 12. Because the first EPDM ring 49 is pressed together with the glass at this time, the air in the first gear suction cup 48 is isolated from the outside air. During the process of the first vacuum pump 10 drawing air from the first gear suction cup 48, if the first sensor 4 does not send a signal... When the main control chip 25 sends a signal, it indicates that there is still air inside the first gear suction cup 48 and it is not yet a vacuum. At this time, the vacuum pump continues to suck the air inside the first gear suction cup 48. When the first sensor 4 sends a signal to the main control chip 25, it indicates that the inside of the first gear suction cup 48 is close to a vacuum and the first gear suction cup 48 has been suctioned onto the glass. At this time, the first EPDM ring 49 and the second EPDM ring 57 of the two gear suction cups on the machine are both suctioned onto the glass, which completes the preliminary work for the main control chip 25 to send the next instruction.

[0087] Furthermore, the infrared transmitting and receiving module includes an infrared receiver and an infrared transmitter. The infrared receiver includes: a main control chip 25, a driver chip 18, a second infrared receiver head 52, and a first infrared receiver head 23.

[0088] The main function of this module is to allow users to select the operating mode via buttons on the remote control. By selecting the operating mode, the machine can start working from the far left, far right, or far bottom. Another function is that after the machine has finished its work, it can be controlled via the remote control to stop at its current position and perform some special tasks. These are accomplished through programmed code.

[0089] Furthermore, the water spray module includes a main control chip 25, a driver chip 18, a water reservoir 7, a water pump 42, a first water sprayer 50, a second water sprayer 55, a first rectifier diode 69, a second rectifier diode 70, a fifth solenoid valve 71, and a sixth solenoid valve 72.

[0090] When the main control chip 25 sends a command (1.0) to the driver chip 18, the water pump 42 is powered on. At the same time, the first rectifier diode 69 and the sixth solenoid valve 72 are turned on, but the second rectifier diode 70 and the fifth solenoid valve 71 are not turned on. The water in the water pump 42 flows into the first sprayer 50 through the sixth solenoid valve 72. The first sprayer 50 is a very thin tube with a row of micro holes on the tube wall. When the water pump works, it generates water pressure, and the micro holes on the first sprayer 50 will spray out a mist of water. When the main control chip 25 sends a command (1.1 or 0.0) to the driver chip 18, the driver chip 18 no longer supplies power to the sixth solenoid valve 72 and the first rectifier diode 69, and water is no longer sprayed. When the main control chip 25 sends the (0.1) instruction to the driver chip 18, the water pump 42 is powered on. Simultaneously, the second rectifier diode 7070 and the fifth solenoid valve 71 are turned on, but the first rectifier diode 69 and the sixth solenoid valve 72 are not turned on. The water in the pump flows through the fifth solenoid valve 71 into the second sprayer 55. The second sprayer 55 is a very thin tube with a row of micro-holes on its wall. When the water pump works, it generates water pressure, causing the micro-holes on the second sprayer 55 to spray out a mist of water. When the main control chip 25 sends the (0.1) instruction to the driver chip 18, the water pump 42 is powered on. At the same time, the second rectifier diode 7070 and the fifth solenoid valve 71 are turned on, but the first rectifier diode 69 and the sixth solenoid valve 72 are not turned on. The water in the pump flows through the fifth solenoid valve 71 into the second sprayer 55. The second sprayer 55 is a very thin tube with a row of micro-holes on its wall. When the water pump works, it generates water pressure, causing the micro-holes on the second sprayer 55 to spray out a mist of water. When chip 18 sends a command (1.1 or 0.0), the driver chip 18 stops supplying power to the fifth solenoid valve 71 and the second rectifier diode 70. Water spraying ceases at this point because the first sprayer 50 and the second sprayer 55 are long tubes with a row of micro-holes. When spraying water, this allows water to reach the entire glass surface, unlike some machines on the market that only have one or two nozzles, which are limited in that they can only spray a portion of the glass, leaving a large area untouched. This type of sprayer solves this problem. Based on the unidirectional conductivity of diodes, the function of the first rectifier diode 69 and the second rectifier diode 70 is that when the power supply polarity changes, only one diode is conducting, while the other is not. Similarly, only one of the two sprayers is spraying water. When the water pump 42 is working, regardless of polarity, as long as it is powered on, the pump will operate, only controlling which sprayer is active. This allows for precise control of which sprayer is engaged based on actual conditions.

[0091] 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 accordingly. When the machine reaches the state where water spraying is required, the main control chip 25 sends a command to the driver chip 18. The driver chip 18 then activates the water spraying device based on the received command. At this time, water flows from the water reservoir 7 through the fifth solenoid valve 71 and the sixth solenoid valve 72 to either the first sprayer 50 or the second sprayer 55. Due to water pressure, the water is sprayed out from the micro-holes on the sprayers. Furthermore, the infrared emitting module can also control which sprayer operates through the program.

[0092] The function of this part is to replenish water when the machine is running. The wiping cloth will consume water. If there is no water replenishment, the wiping cloth will dry out and the wiping effect will be very poor. Therefore, the function of this module is to replenish water.

[0093] All solenoid valves and motors have two wires, each connected to a different I / O port on one end of the driver chip 18. The other end of the driver chip 18 has a corresponding row of I / O ports, which connect to different I / O ports on the main control chip 25. Programming is done based on the wires connected to the different I / O ports on the main control chip 25. The positive and negative terminals of the main power supply are connected to the corresponding terminals on the driver chip via a switch. The main control chip 25 obtains a 5-volt operating voltage after the power supply is stepped down by a buck chip following the switch.

[0094] Furthermore, the machine also includes a seventh sensor 46, an eighth sensor 60, a sensor group 53, a sixth sensor 41, a fifth sensor 37, a first sensor 4, a second sensor 9, a third sensor 11, a fourth sensor 35, and an angle sensor group 30. The angle sensor group 30 has four sensors distributed around the rotating pointer 28. When the machine is working on the window glass, the rotating pointer 28 is always perpendicular to the ground. When the machine rotates, one of the four sensors in the angle sensor group 30 aligns with the rotating pointer 28. When this sensor aligns with the rotating pointer 28, it sends a signal to the main control chip 25. The main control chip 25 determines the machine's direction and position based on this signal and sends the next correct instruction for the machine to execute. The remaining sensors mainly determine the next step of the machine based on the signals they send to the main control chip 25, which in turn determines the signal received. These sensors are involved in the actions of the rotation module, suction module, lifting module, and telescopic module. Each sensor in the angle sensor group 30 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 25 for external power supply, and the signal wire is connected to the I / O port of the main control chip 25. 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 25 for external power supply, and the other wire is connected to the I / O port of the main control chip 25.

[0095] like Figure 20 The diagram shows the machine's trajectory when wiping a corner of a window. 1. Suction cup A adheres to the glass, and the machine moves in the reverse direction. The machine stops when the sensor at the front of suction cup B contacts the window frame. 2. The machine then begins to rotate forward around suction cup A. The machine stops when the sensor at the front of suction cup B contacts the window frame. 3. The lifting plate on suction cup A stops rotating when the motor on the wiping cloth plate contacts the lower glass. 4. Suction cup B adheres to the glass, and the motor connected to the rack rotates. The machine stops extending forward when it reaches its maximum extension. 5. Suction cup A adheres to the glass, and the motor connected to the rack reverses direction, causing suction cup B to move closer to suction cup A. 6. Suction cup B adheres, and the motor connected to the rack rotates forward, pushing suction cup A out. The motor stops when the sensor at the front of suction cup A contacts the window frame. 7. Suction cup A adheres, and the motor connected to the rack reverses direction, causing suction cup B to move closer to suction cup A. The motor stops when suction cup B reaches its initial position. 8. Both suction cups A and B are attached to the glass, and the motor on the lifting plate works at the same time, stopping when it reaches the initial position.

[0096] Furthermore, the safety module includes a safety rope module and a safety net module. The safety rope module includes: an internal gear 62, an eccentric wheel 63, a central shaft 64, a central component 65, a helical spring 66, and a safety rope 67.

[0097] An eccentric wheel 63 is provided inside the internal gear 62. The eccentric wheel 63 is fixedly connected to the central shaft 64 through the central member 65. A safety rope 67 is wound around the middle of the central shaft 64, and a helical spring 66 is provided at the end of the central shaft 64. During the descent, the safety rope 67, under the action of the helical spring 66, will be retracted into the safety rope box. When the machine and the safety rope box are on the same horizontal plane, the distance between the machine and the safety rope box is the shortest. As the machine continues to fall from this point, because the machine is in free fall, the speed is very high. At this time, the speed of the eccentric wheel 63 driven by the central shaft 64 also exceeds the normal pull-out speed. At this time, the eccentric wheel 63 and the central component 65 no longer revolve in a circular motion with the central shaft 64 as the center. The eccentric wheel 63 will move towards the internal gear 62, and the teeth of the internal gear 62 and the eccentric wheel 63 will mesh together. Because the central component 65, the central shaft 64 and the eccentric wheel 63 are integrated, when the eccentric wheel 63 meshes with the internal gear 62, the safety rope 67 stops moving along with the central component 65, the central shaft 64 and the eccentric wheel 63. Safety rope 67 is an elastic rope. When the central shaft 64 stops rotating, the machine, due to its own weight, acceleration, and downward force, will stretch safety rope 67 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 safety rope 67 is connected to a loop, which fits into the groove at the upper end of the power charging post 2. When the machine rotates, the loop prevents safety rope 67 from tangling around the machine. Also, because the power cord and safety rope 67 are integrated, they appear as a single line, preventing the two lines from getting tangled. (Safety net module as follows...) Figure 34 As shown, the adhesive rings 74 are fixed to the four corners of the window. Then, the safety net telescopic pole 73 is looped onto the adhesive rings 74. The safety rope 67 passes through the safety net telescopic pole 73, and the safety net 75 is looped onto the safety net telescopic pole 73. Figure 34 As shown, if the safety rope 67 breaks, the safety net 75 below is also safe and the machine can be put on the safety net 75. This actually adds three layers of protection to the machine, ensuring that the machine will not fall to the ground, and at the same time, protecting the machine from damage to the greatest extent.

[0098] Furthermore, the central processing unit system module includes a main control chip 25 and a driver chip 18. One row of I / O ports on the driver chip 18 is connected to the I / O ports on the main control chip 25, and the other row of I / O ports is connected to the terminals of the first solenoid valve 12, the second solenoid valve 13, the third solenoid valve 33, and the fourth solenoid valve 34, the first motor 5, the first vacuum pump 10, the second vacuum pump 36, the telescopic motor 26, the fifth solenoid valve 71, the sixth solenoid valve 72, and the fourth motor 39. The power supply of the driver chip 18 is connected to the power switch 22. The polarity of the power supply received by the first solenoid valve 12, the second solenoid valve 13, the third solenoid valve 33, the fourth solenoid valve 34, the first motor 5, the first vacuum pump 10, the second vacuum pump 36, the telescopic motor 26, the third solenoid valve 33, the fourth solenoid valve 34, and the fourth motor 39 is obtained by sending the high and low levels of the corresponding I / O on the main control chip 25 to the driver chip 18. One function of the driver chip 18 is a bridge power polarity converter. When chip 25 sends a command (1.0) to the corresponding terminal of driver chip 18, the positive terminal of driver chip 18 is connected to the positive terminal and the negative terminal to the negative terminal. When the main control chip 25 sends a command (0.1) to the corresponding terminal of driver chip 18, the corresponding terminal of driver chip 18 changes from positive to positive and negative to negative to positive. When the main control chip 25 sends a command (0.0) or (1.1) to the corresponding terminal of driver chip 18, driver chip 18 is de-energized. This allows control of the forward and reverse rotation of the motor and the energization and de-energization of the solenoid valve. The power supply for the main control chip 25 is obtained by stepping down the voltage from driver chip 18 to obtain a 5-volt power supply. The sensor signal line is connected to the I / O port on the main control chip.

[0099] Furthermore, the power supply system module includes: a power charging post 2, a battery 17, a power switch 22, a power cord 84 (integrated with the safety rope 67), and a power adapter 85. The power charging post 1 is used for external power supply, the battery 17 serves as a backup power source; in the event of an external power outage, the battery 17 can supply power to the machine. The power switch 22 acts as a control device, controlling the on / off state of the power supply. Figure 32 The diagram shows a cross-sectional view of the power cord 84 within the safety rope 67, where A represents the state of the safety rope 67 when it is not stretched, and B represents the state of the safety rope 67 when it is stretched. The power cord 84 is installed within the groove of the safety rope 67. When the safety rope 67 is not stretched, the power cord 84 is arranged in a V-shape within the safety rope 67; when stretched, it is as shown in B. Figure 33 As shown, power plugs 86 are installed at both ends of the safety rope 67, and a step-down chip 87 is installed on the power adapter 85. Figure 23 The diagram shows the structure of the power charging column 2, where C is the power charging socket and D is a ring fitted onto the power charging column 2, with a safety rope on the ring.

[0100] Furthermore, the wiping plate module includes a wiping plate base plate, a removable wiping cloth plate 91, and a wiping cloth; the removable wiping cloth plate 91 is of two types, one is a regular flat plate, and the other has an uneven surface with many raised particles.

[0101] Furthermore, the handle module includes: a handle 20, a toggle switch 21, a power switch 22, an infrared receiver, and a handle telescopic rod assembly (composed of a column 76 and a round tube 77), with a first spring 78 mounted next to it; below the toggle switch 21 is a vertical plate 79, which is fixed to the toggle switch 21 as one piece. The vertical plate 79 has a round hole 80 at the top and bottom, and a horizontal rod 81 at the top of the column 76. When the toggle switch 21 is toggled to the left, the vertical plate 79 is no longer fitted onto the horizontal rod 81 on the column 76. Because the first spring 78 is under pressure, it will push the handle 20 upward. Then, the handle 20 is pulled upward to its maximum length by hand, and then the toggle switch 21 is toggled to the right. At this time, the round hole 80 under the vertical plate 79 is fitted onto the horizontal rod 81 on the column 76, and the handle 20 is fixed and no longer moves up and down. When you want to retract handle 20, move toggle switch 21 to the left. At this point, the upright plate 79 is no longer fitted onto the horizontal bar 81 on the column 76. Then, gently press down; when you can no longer press down, it indicates that handle 20 has reached its bottom. Then, move toggle switch 21 to the right. The round hole 80 on the upright plate 79 will then fit onto the horizontal bar 81 on the column 76, and handle 20 will no longer move up or down, remaining fixed in this position. Since current window cleaning machines on the market cannot clean the four corners of windows, this product incorporates a lifting module and a telescopic module in its design to solve this problem. The main function of these modules is to address the issue of inaccessible corners. By sequentially executing different programs through the lifting and telescopic modules, the problem of inaccessible corners can be perfectly solved. This is unprecedented in similar products and represents a significant improvement and breakthrough. Figure 20 This diagram shows the basic working trajectory and flow chart of the machine when wiping one corner of a window. It includes the workflow of the adsorption module, the rotation module, the telescopic module, and the lifting module. With the detailed description of the specific working steps and processes of each module in the adsorption module, rotation module, telescopic module, and lifting module, this diagram provides a more intuitive understanding of the working trajectory and process of the machine when wiping the four corners of a window.

[0102] When the machine is working, it can send instructions to the main control chip 25 via the remote control to select a specific working mode. If no instructions are sent to the main control chip 25, the machine will start working in the default working mode. Figure 29 and Figure 30 These are the two most basic working modes of a machine.

[0103] This utility model provides a fully automatic window cleaning machine that optimizes and solves the problems that similar products cannot solve in actual operation, such as the following situations:

[0104] 1. Problems with the machine slipping and falling due to lack of grip;

[0105] 2. The problem of excessive noise;

[0106] 3. The problem of not being able to wipe the four corners of the window;

[0107] 4. The problem of the machine not being damaged when it is accidentally dropped.

[0108] 5. The problem of low work efficiency.

[0109] 6. Uneven water spraying problem.

[0110] Existing products on the market all encounter the five problems mentioned above in actual operation, but none of them can perfectly solve these problems. This product, however, technically solves all five problems, ensuring that the glass cleaning machine will not slip or fall 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, which is a drawback. This product's design is more reasonable, allowing cleaning of all four corners—a significant improvement and breakthrough. The safety rope of similar products does not consider cushioning, so if the machine falls, it will generate a strong, direct pulling force without buffering, potentially damaging the internal structure. This product incorporates cushioning in its design, providing protection in the event of a fall.

[0111] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
