Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and specifically to a cleaning equipment with a floating plate vibration mechanism. Background Art

[0002] With the economic development, more and more people live in high-rise buildings. For the sake of cleaning efficiency and safety, automatic cleaning equipment such as window cleaning machines has been developed. A cleaning device and a traveling device are provided at the bottom of the window cleaning machine. The traveling device drives the window cleaning machine to move outside the window, thereby driving the cleaning device to clean the glass window. The window cleaning machine can be used for high-altitude cleaning of glass windows. Since it is difficult to clean glass windows at high altitudes, the cleaning cycle of the glass windows of some buildings is often relatively long. Therefore, it is easy to leave stubborn stains that are difficult to remove. The cleaning device in the existing window cleaning machine is static and only moves with the window cleaning machine to achieve the purpose of cleaning the window, resulting in low cleaning efficiency and poor cleaning effect of the window, and it is difficult to remove stubborn stains on the glass window.

[0003] The present invention is studied and proposed in view of the deficiencies of the prior art. Summary of the Invention

[0004] Regarding the problem that the cleaning device in the existing window cleaning machine mentioned above is static and only moves with the window cleaning machine to achieve the purpose of cleaning the window, resulting in low cleaning efficiency and poor cleaning effect of the window, and it is difficult to remove stubborn stains on the glass window.

[0005] The technical solution adopted by the present invention to solve its technical problems is:

[0006] A cleaning device with a floating plate vibration mechanism, comprising a device main body. The device main body includes a base plate, a floating plate vibration mechanism, a vibration plate and a scraping mechanism. One side of the vibration plate is connected to the floating plate vibration mechanism, and the other side is used to connect to a cleaning cloth. The floating plate vibration mechanism is used to drive the vibration plate to perform a first linear reciprocating motion relative to the base plate. The scraping mechanism includes a scraping member and a driving mechanism connected to the scraping member. The scraping member can extend out of the device main body through the driving mechanism to contact a cleaning surface and can perform a second linear reciprocating motion relative to the cleaning surface. The driving mechanism includes a telescopic device, a moving device and a first rotating device provided in the device main body. The scraping member is connected to the moving device through the first rotating device. The moving device is connected to the telescopic device. The scraping member has a storage state and a working state relative to the moving device. The scraping member is parallel to the moving device in the storage state, and the scraping member is perpendicular to the moving device in the working state. The first rotating device is used to rotate the scraping member so that the scraping member can be switched between the storage state and the working state. The moving device is used to make the scraping member in the working state perform a second linear reciprocating motion relative to the device main body.

The guiding member is connected to the telescopic device. One side of the moving member is slidably connected to the guiding member, and the other side is connected to the first rotating device. The two ends of the guiding member are provided with a first sensor and a second sensor opposite to the moving member. When the moving member moves relative to the guiding member to contact the first sensor or the second sensor, it triggers the moving member to move in the opposite direction relative to the guiding member, so that the moving member drives the scraping member to perform a second linear reciprocating motion relative to the cleaning surface through the first rotating device.

Locking devices are provided in both the first rotating joint and the second rotating joint.

[0010] A cleaning device with a floating plate vibration mechanism as described above. The floating plate vibration mechanism includes a floating plate vibration assembly disposed between the substrate and the vibration plate, and a vibration driving device disposed adjacent to the floating plate vibration assembly. The vibration driving device drives the vibration plate to perform a circular reciprocating motion, and the floating plate vibration assembly is used to guide the vibration plate to convert from the circular reciprocating motion to a first linear reciprocating motion.

[0011] A cleaning device with a floating plate vibration mechanism as described above. The floating plate vibration assembly includes a vibration floating plate mounted on the substrate. A first connecting portion is provided on the vibration floating plate, and a guiding hole is provided on the vibration plate along the same direction as the first linear reciprocating motion. The first connecting portion passes through the guiding hole and is connected to the vibration plate through a limiting member. The vibration plate performs a first linear reciprocating motion relative to the substrate through the guiding hole and drives the vibration floating plate to move.

[0012] A cleaning device with a floating plate vibration mechanism as described above. A second connecting portion is provided on the vibration floating plate. A groove is provided at a position on the substrate corresponding to the second connecting portion, and a first fixing column is provided in the groove and protrudes from the port of the groove. The second connecting portion is connected to the first fixing column, so that the vibration floating plate is connected to the substrate. The floating plate vibration assembly further includes an elastic member sleeved on the second connecting portion and extending into the groove. The elastic member swings in the groove as the vibration floating plate moves.

[0013] A cleaning device with a floating plate vibration mechanism as described above. The vibration driving device includes a motor mounted on the substrate, an input shaft provided at the end of the motor, and an eccentric assembly sleeved on the input shaft. An active area is provided on the vibration plate opposite to the eccentric assembly. The eccentric assembly extends into the active area and rotates through the input shaft, so that the vibration plate generates a circular reciprocating motion.

[0014] A cleaning device with a floating plate vibration mechanism as described above, the eccentric component includes a rotating shaft and an eccentric wheel fixedly connected to the rotating shaft. The eccentric wheel is not coaxial with the input shaft. One end of the rotating shaft is cooperatively connected to the input shaft, and the other end of the rotating shaft is sleeved with an eccentric wheel. The eccentric wheel extends into the active area. The eccentric wheel is driven by the input shaft to perform a circular reciprocating motion in the active area, so that the vibrating plate generates a circular reciprocating motion.

[0015] A cleaning device with a floating plate vibration mechanism as described above. The vibrating floating plate is further provided with a second fixing column. The floating plate vibration assembly further includes a guide wheel sleeved on the second fixing column. The edge of the guide wheel is in contact with the vibrating plate. The guide wheel is used to assist the vibrating plate to perform a first linear reciprocating motion.

[0016] The beneficial effects of the present invention are:

[0017] 1. The floating plate vibration mechanism is arranged on the substrate and is correspondingly connected to the vibrating plate. A cleaning cloth is installed at the bottom of the vibrating plate for friction cleaning the glass surface. The cleaning surface can be understood as the contact surface to be cleaned on the glass window. The vibrating plate performs a first linear reciprocating motion relative to the substrate through the floating plate vibration mechanism, thereby driving the cleaning cloth to perform a rapid first linear reciprocating motion relative to the cleaning surface, enabling the cleaning cloth to simulate the motion of manually wiping the window back and forth, enhancing the friction times and friction frequency of the cleaning cloth against the cleaning surface, and further enhancing the cleaning ability of the device main body, improving the cleaning efficiency and cleaning effect of the device main body;

[0018] 2. In order to be able to remove stubborn stains on the glass window. For example, long - accumulated thick dust will form dirt on the glass window. Thicker dust is easier to clean after being wetted and then wiped or scraped off. The moisture in the cleaning cloth can also soften the dirt, making it easier to fall off the glass window. Therefore, after the wetted cleaning cloth wipes the cleaning surface, the scraping mechanism is used to scrape off the remaining dust and other small debris and water stains on the cleaning surface, achieving the purpose of strong cleaning, and further improving the cleaning effect and cleaning efficiency of the device main body;

[0019] 3. The scraping member has a working state and a storage state. After the cleaning cloth wipes the cleaning surface, the scraping member in the storage state extends out of the device main body through the telescopic device to contact the cleaning surface. At this time, the scraping member is located outside the cleaning cloth. The scraping member rotates through the first rotating device to switch to the working state. The scraping member in the working state can move downwards relative to the device main body through the moving device, so as to realize the downward movement of the scraping member relative to the cleaning surface, so that the scraping member can scrape off the sundries on the cleaning surface. The scraping member can simulate manual scraping of the sundries on the glass window from top to bottom. Then, the scraping member moves upwards relative to the device main body through the moving device to reset, so that the scraping member realizes the second linear reciprocating motion, enhancing the coherence of the operation of the telescopic device, the moving device, the first rotating device, and the scraping member, thereby improving the cleaning efficiency of the scraping mechanism.

[0031] The following will describe the embodiments of the present invention in detail with reference to the accompanying drawings.

[0032] As Figure 1 shown in FIG. -10, a cleaning device with a floating plate vibration mechanism according to this embodiment includes a device main body. The device main body includes a base plate 1, a floating plate vibration mechanism 2, a vibration plate 3, and a scraping mechanism 4. One side of the vibration plate 3 is connected to the floating plate vibration mechanism 2, and the other side is used to connect to a cleaning cloth 5. The floating plate vibration mechanism 2 is used to drive the vibration plate 3 to perform a first linear reciprocating motion relative to the base plate 1. The scraping mechanism 4 includes a scraping member 41 and a driving mechanism connected to the scraping member 41. The scraping member 41 can extend out of the device main body through the driving mechanism to contact the cleaning surface and can perform a second linear reciprocating motion relative to the cleaning surface. The driving mechanism includes a telescopic device 42, a moving device 43, and a first rotating device 44 provided in the device main body. The scraping member 41 is connected to the moving device 43 through the first rotating device 44. The moving device 43 is connected to the telescopic device 42. The scraping member 41 has a storage state and a working state relative to the moving device 43. The scraping member 41 is parallel to the moving device 43 in the storage state, and the scraping member 41 is perpendicular to the moving device 43 in the working state. The first rotating device 44 is used to rotate the scraping member 41 to enable the scraping member 41 to switch between the storage state and the working state. The moving device 43 is used to make the scraping member 41 in the working state perform a second linear reciprocating motion relative to the device main body. The telescopic device 42 can extend or contract to enable the moving device 43 to drive the scraping member 41 to extend out of the device main body or be stored in the device main body.

[0033] The cleaning device includes a window cleaning machine, a floor washing machine, a floor mopping machine, etc. In this embodiment, a window cleaning machine is taken as an example. In this embodiment, the floating plate vibration mechanism 2, the vibration plate 3, and the scraping mechanism 4 are installed on the device main body through the base plate 1 for use. The device main body further includes a traveling mechanism. The vibration plate 3 is arranged outside the traveling mechanism. The floating plate vibration mechanism 2 is arranged on the base plate 1 and is correspondingly connected to the vibration plate 3. A cleaning cloth 5 is installed at the bottom of the vibration plate 3 for frictionally cleaning the glass surface. The cleaning surface can be understood as the contact surface to be cleaned on the glass window. The vibration plate 3 performs a first linear reciprocating motion relative to the base plate 1 through the floating plate vibration mechanism 2, thereby driving the cleaning cloth 5 to perform a rapid first linear reciprocating motion relative to the cleaning surface, enabling the cleaning cloth 5 to simulate the motion of manually wiping the window back and forth, enhancing the number of friction times and the friction frequency of the cleaning cloth 5 against the cleaning surface, and further enhancing the cleaning ability of the device main body and improving the cleaning efficiency and cleaning effect of the device main body.

[0034] In addition, in order to remove stubborn stains on the glass window, for example, long-accumulated thick dust will form dirt on the glass window. After the relatively thick dust is wetted, it is easier to clean by wiping or scraping. The moisture in the cleaning cloth 5 can also soften the dirt, making it easier to fall off the glass window. Therefore, after the wetted cleaning cloth 5 wipes the cleaning surface, the scraping mechanism 4 is used to scrape off the remaining dust and other small debris and water stains on the cleaning surface, so as to achieve the purpose of strong cleaning, further improving the cleaning effect and cleaning efficiency of the device body. In this embodiment, the scraping member 41 is preferably a scraping strip, a scraping rod, etc. As Figure 1 shown in FIG. 3, the scraping member 41 has a working state and a storage state relative to the moving device 43. Figure 1 The scraping member 41 in FIG. 4 is in the storage state. Figure 3The described scraping member 41 in it is in a working state. The scraping member 41 in the storage state extends out of the device main body through the telescopic device 42 to contact the cleaning surface, and rotates through the first rotating device 44. After the scraping member 41 is switched from the storage state to the working state, it can perform a second linear reciprocating motion relative to the cleaning surface through the moving device 43 to scrape off the residual debris on the cleaning surface. For example, when the device main body moves in the left-right direction on the glass window through the traveling mechanism, the vibrating plate 3 performs a first linear reciprocating motion in the up-down direction relative to the cleaning surface through the floating plate vibration mechanism 2. At this time, the moving direction of the first linear reciprocating motion performed by the vibrating plate 3 is perpendicular to the moving direction of the traveling mechanism to prevent the vibrating plate 3 from interfering with the normal operation of the traveling mechanism. The cleaning cloth 5 is driven by the vibrating plate 3 to perform a first linear reciprocating motion in the up-down direction relative to the cleaning surface. After the cleaning cloth 5 wipes the cleaning surface, the scraping member 41 extends out of the device main body through the telescopic device 42 to contact the cleaning surface. At this time, the scraping member 41 is located outside the cleaning cloth 5, and the scraping member 41 can move downward relative to the device main body through the moving device 43 to realize the downward movement of the scraping member 41 relative to the cleaning surface, so that the scraping member 41 can scrape off the debris on the cleaning surface. The scraping member 41 can simulate the top-down scraping of debris on the glass window by a human. Then, the scraping member 41 moves upward relative to the device main body through the moving device 43 to reset, so that the scraping member 41 realizes the second linear reciprocating motion. As the device main body continues to travel, the second linear reciprocating motion is performed on different positions of the cleaning surface, enhancing the coherence of the operation of the telescopic device 42, the moving device 43, the first rotating device 44, and the scraping member 41, thereby improving the cleaning efficiency of the scraping mechanism 4. Preferably, in order to ensure that the scraping member 41 can move downward relative to the cleaning surface orderly through the driving mechanism, the traveling mechanism is set to move horizontally a certain distance relative to the cleaning surface and then pause for a certain period of time, so that the scraping member 41 has sufficient time to move downward relative to the cleaning surface. When the scraping member 41 starts to reset, the traveling mechanism continues to drive the device main body to move. Further preferably, two sets of the scraping mechanisms 4 are oppositely arranged on both sides of the substrate 1, and the scraping mechanisms 4 can be controlled to operate independently to adapt to different moving directions of the device main body.

[0035] Further, the device body further includes a casing 7 provided on the upper part of the substrate 1. The casing 7 is provided with a first opening 71 above the substrate 1 and a second opening 72 between the first opening 71 and the substrate 1. The first opening 71 allows the mobile device 43, the first rotating device 44, and the scraping member 41 to pass through. The driving mechanism further includes a second rotating device 45 provided on the substrate 1 and connected to the telescopic device 42. The second rotating device 45 drives the telescopic device 42 to move up and down relative to the substrate 1, thereby driving the scraping member 41 to move up and down relative to the cleaning surface. The second opening 72 allows the telescopic device 42 to pass through. As Figure 1 shown in FIG. 4, in this embodiment, a storage space is provided in the device body to accommodate the scraping member 41, the first rotating device 44, the mobile device 43, and the telescopic device 42. The telescopic device 42 includes two sets of electric telescopic rods connected to both ends of the mobile device 43. The second rotating device 45 corresponds to the two electric telescopic rods one by one to ensure the balance of the movement of the mobile device 43 relative to the first opening 71. The second rotating device 45 is detachably installed between the traveling mechanism and the floating plate vibration assembly 21. One end of the electric telescopic rod is connected to the second rotating device 45 and is placed above the floating plate vibration assembly 21. The other end of the electric telescopic rod is fixedly connected to the mobile device 43. The mobile device 43 is connected to the upper part of the first rotating device 44. The scraping member 41 is connected to the lower part of the first rotating device 44; as Figure 1 shown, Figure 1The scraping member 41 therein is in a retracted state. When the scraping member 41 is in the retracted state, the scraping member 41 is parallel to the mobile device 43. At this time, the scraping member 41, the first rotating device 44, and the mobile device 43 can be contracted through the telescopic device 42 and retracted from the first opening 71 into the storage space. The scraping member 41, the first rotating device 44, the mobile device 43, and the telescopic device 42 are all placed above the floating plate vibration assembly 21 and the vibration driving device 22. When the telescopic device 42 extends, the scraping member 41, the first rotating device 44, and the mobile device 43 can be extended from the first opening 71 to the outside of the device body. The scraping member 41 rotates through the first rotating device 44 to be perpendicular to the mobile device 43, so that the scraping member 41 is converted from the retracted state to the working state. At this time, the second rotating device 45 rotates to drive the telescopic device 42 to move downward toward the cleaning surface, and drives the scraping member 41 to move downward to contact the cleaning surface. During the downward movement, the electric telescopic rod correspondingly passes through the second opening 72. At this time, the mobile device 43 is used to drive the first rotating device 44 to move downward relative to the cleaning surface from top to bottom, thereby driving the scraping member 41 to move downward relative to the cleaning surface from top to bottom to scrape off residual debris, water stains, etc. on the glass window. Through the above settings, the scraping member 41 can simulate the action of manually scraping the glass window and scrape off the debris from top to bottom along the glass window, so that the debris can fall downward, and the cleaning surface is further cleaned by the scraping mechanism 4 to achieve the purpose of strongly cleaning the glass window, enhancing the cleaning effect and cleaning ability of the device body. Moreover, the scraping direction of the scraping member 41 is perpendicular to the traveling direction of the device body to prevent the scraped debris from falling onto the device body, thereby ensuring the overall cleanliness of the device body. It should be noted that the second rotating device 45 can adjust the fitting degree between the scraping member 41 and the cleaning surface by adjusting the rotation angle.On the other hand, since some glass windows have frames on their outer edges, the device body generally starts from a position close to the frame and moves along the cleaning surface in a set manner, and gradually approaches the frame on the other side during the walking process. Since the frame will block the normal operation of the scraping member 41 when the device body approaches the frame, in order to solve the above problem, a corresponding distance meter is provided on the device body to detect the distance between the device body and the surrounding frames, and a safety distance is set for the distance meter. The safety distance is greater than or equal to the sum of the length of the scraping member 41 in the working state, the extended length of the telescopic device 42, and the length of the second rotating device 45 after rotating downward, so as to ensure that the scraping member 41 has sufficient space to extend and perform the second linear reciprocating motion relative to the cleaning surface. ; When the rangefinder detects that the device body is constantly approaching the frame, it is judged based on the detected distance signal that the distance between the device body and the frame is less than the safety distance. At this time, the second rotating device 45 is triggered to rotate in the opposite direction by a certain angle to reset, driving the telescopic device 42, the moving device 43 and the scraping member 41 to rise and reset in the direction away from the cleaning surface, and then the telescopic device 42 is triggered to contract and drive the moving device 43 and the scraping member 41 to be stored in the device body to avoid the scraping mechanism 4 from colliding with the frame and being damaged, thereby protecting the device body to extend its service life and reduce the user's maintenance cost; in addition, a rangefinder can also be set at the bottom of the device body to realize the function of detecting and identifying the edge of the frameless glass window to prevent the device body from falling in the air.

[0036] Preferably, the moving device 43 includes a moving part 431 and a guide member 432. The guide member 432 is connected to the telescopic device 42. One side of the moving part 431 is slidably connected to the guide member 432 and the other side is connected to the first rotating device 44. The two ends of the guide member 432 are provided with a first sensor and a second sensor opposite to the moving part 431. When the moving part 431 moves relative to the guide member 432 until it contacts the first sensor or the second sensor, the moving part 431 is triggered to move in the opposite direction relative to the guide member 432, so that the moving part 431 drives the scraping part 41 to perform a second linear reciprocating motion relative to the cleaning surface through the first rotating device 44. Figure 1 and Figure 2As shown, in this embodiment, the moving member 431 preferably adopts a slider, the guiding member 432 preferably adopts a guide rail, the second rotating device 45 rotates downward by a certain angle relative to the substrate 1, and drives the moving device 43 to move downward by a certain distance through the telescopic device 42, so that the scraping member 41 contacts the cleaning surface. At this time, the moving device 43 is triggered to start, and the moving member 431 moves relative to the guiding member 432 from the first sensor towards the second sensor, so that the scraping member 41 moves downward relative to the cleaning surface. When the moving member 431 continuously approaches and contacts the second sensor, the moving member 431 is triggered to move and reset from the second sensor towards the first sensor, so that the scraping member 41 normally performs the second linear reciprocating motion. The moving device 43 has a simple structure and is easy to implement, enhancing the intelligent use of the device body, making the device body more worry-free and convenient to use, and improving the user experience.

[0037] Preferably, the second rotating device 45 is installed on the substrate 1 through a mounting seat 46. The second rotating device 45 includes a first rotating joint 451 rotatably connected to the mounting seat 46, a second rotating joint 452 rotatably connected to the telescopic device 42, and a connecting arm 453 disposed between the first rotating joint 451 and the second rotating joint 452. The connecting arm 453 rotates relative to the mounting seat 46 through the first rotating joint 451, and the connecting arm 453 rotates relative to the telescopic device 42 through the second rotating joint 452, so that the telescopic device 42 performs a lifting action. Locking devices are provided in both the first rotating joint 451 and the second rotating joint 452. As Figure 4 shown, in this embodiment, one end of the connecting arm 453 rotates by a certain angle relative to the mounting seat 46 through the first rotating joint 451 towards its lower side or upper side, and at the same time drives the other end of the connecting arm 453 to rotate towards its lower side or upper side relative to the telescopic device 42 through the second rotating joint 452. After the connecting arm 453 rotates, the first rotating joint 451 and the second rotating joint 452 are self-locked and fixed through the corresponding locking devices, so as to enhance the stability of the telescopic device 42; preferably, the first rotating joint 451 is provided with a rotating shaft rotatably connected to the mounting seat 46, and this rotating shaft is driven by a motor. The motor is set to drive the rotating shaft to rotate by a certain angle and then lock the rotating shaft to achieve the self-locking and fixing of the first rotating joint 451; the structure of the second rotating joint 452 is similar to that of the first rotating joint 451.

[0038] Specifically, the floating plate vibration mechanism 2 includes a floating plate vibration assembly 21 disposed between the substrate 1 and the vibration plate 3 and a vibration driving device 22 disposed adjacent to the floating plate vibration assembly 21. The vibration driving device 22 drives the vibration plate 3 to perform a circular reciprocating motion, and the floating plate vibration assembly 21 is used to guide the vibration plate 3 to convert from the circular reciprocating motion to a first linear reciprocating motion. In this embodiment, as Figure 3 and Figure 5 shown, there are two floating plate vibration assemblies 21, which are respectively disposed on both sides of the vibration driving device 22. The vibration plate 3 is covered and installed below the two floating plate vibration assemblies 21 and the vibration driving device 22. The floating plate vibration mechanism 2 can be adapted to a long-shaped cleaning device such as a cleaning cloth 5, so that the whole of the cleaning cloth 5 can generate the first linear reciprocating motion along with the vibration plate 3, thereby more effectively simulating the motion of manually wiping the window back and forth, and effectively enhancing the cleaning ability and cleaning efficiency of the cleaning device.

[0039] Furthermore, the floating plate vibration assembly 21 includes a vibration floating plate 211 installed on the substrate 1. A first connection portion 2111 is provided on the vibration floating plate 211. A guiding hole 31 is provided on the vibration plate 3 along the same direction as the first linear reciprocating motion. The first connection portion 2111 passes through the guiding hole 31 and is connected to the vibration plate 3 through a limiting member 6. The vibration plate 3 performs a first linear reciprocating motion relative to the substrate 1 through the guiding hole 31 and drives the vibration floating plate 211 to move. In this embodiment, as Figure 7 shown, the guiding hole 31 is an elongated hole, which provides a certain movement space for the vibration plate 3 in the direction of the first linear reciprocating motion. There are two guiding holes 31 and their corresponding first connection portions 2111, so that the vibration plate 3 performs the first linear reciprocating motion more stably and smoothly; the limiting member 6 can adopt a screw limiting connection, which is easy to disassemble and assemble and has a low production cost.

[0040] Even further, a second connection portion 2112 is provided on the vibration floating plate 211. A groove 11 is provided at a position on the substrate 1 corresponding to the second connection portion 2112, and a first fixing column 12 is provided in the groove 11 and protrudes from the port of the groove 11. The second connection portion 2112 is connected to the first fixing column 12 so that the vibration floating plate 211 is connected to the substrate 1. The floating plate vibration assembly 21 further includes an elastic member 212 sleeved on the second connection portion 2112 and extending into the groove 11. The elastic member 212 swings in the groove 11 as the vibration floating plate 211 moves. In this embodiment, as Figure 5 and Figure 6As shown, the second connecting part 2112 is located around the vibration floating plate 211. The second connecting part 2112 and the first fixing column 12 can be connected in a position-limiting manner by screws, which is easy to disassemble and assemble and has a relatively low production cost. Moreover, the groove 11 provides a certain range of movement space for the elastic member 212. The vibration plate 3 can drive the vibration floating plate 211 to perform the first linear reciprocating motion, thereby generating a force on the substrate 1 and making the vibration floating plate 211 easily collide with the substrate 1. The swinging of the elastic member 212 in the groove 11 can, to a certain extent, reduce the force of the vibration floating plate 211 on the substrate 1, thereby realizing the function of buffering vibration, further protecting the floating plate vibration mechanism 2 from being easily damaged, increasing the service life of the cleaning device, and also reducing the vibration impact of the cleaning device on the glass window during actual use, thereby enhancing the use safety of the cleaning device.
