Description

Technical Field

[0001] This application relates to the field of everyday cleaning products technology, and in particular to a scraping cleaning device and scraping cleaning components. Background Technology

[0002] Dust and impurities remaining on the surface of glass windows greatly affect their appearance and also hinder indoor light transmission. Therefore, regular cleaning of windows is necessary to maintain their cleanliness. The advent of window cleaners has greatly facilitated window cleaning. A window cleaner mainly consists of a wiping body that is magnetically connected to the glass and a push-pull rod for moving the wiping body. In use, the user moves the wiping body across the glass surface by pushing and pulling the rod, thus simultaneously scraping and cleaning both the inner and outer surfaces of the window. It has high cleaning efficiency and is also very convenient and practical to operate.

[0003] In related technologies, the side of the cleaning body that is in contact with the glass is usually provided with a wiping material and a scraper. The wiping material is used to scrub and clean the glass surface to be cleaned, and can handle larger dirt adhering to the glass surface, while the scraper can scrape off water stains on the glass surface to be cleaned.

[0004] In use, the user moves the wiping body up and down across the glass surface using a push-pull lever to scrape it. When the user moves the wiping body upwards, the squeegee removes water stains, but under gravity, the collected water flows down the sides of the squeegee, forming watermarks. Cleaned areas of the glass surface are easily contaminated by these watermarks. Similarly, when the user moves the wiping body downwards, the collected water flows downwards and spreads, again contaminating cleaned areas. These factors necessitate repeated wiping, which is both time-consuming and laborious, resulting in low cleaning efficiency for existing glass wipers. Summary of the Invention

[0005] This application provides a scraping cleaning device and scraping cleaning components, which have higher cleaning efficiency.

[0006] In a first aspect, a scraping cleaning device is provided, comprising: a scraping component and a posture adjustment assembly, wherein the scraping component is connected to the body of the scraping cleaning device and is capable of scraping a surface to be cleaned in an inclined scraping position and a horizontal scraping position; the posture adjustment assembly is used to adjust the posture of the scraping component, so that the scraping component switches between the inclined scraping position and the horizontal scraping position; when the scraping component moves along a first direction, it is in the inclined scraping position, and a first end of the scraping component is located in front of the moving direction relative to a second end; when the scraping component moves along a second direction, it is in the horizontal scraping position, and the length direction of the scraping component is substantially perpendicular to the second direction; wherein the first end is one end of the scraping component along the length direction, and the second end is the other end of the scraping component along the length direction.

[0007] The scraping cleaning device provided in this application includes a scraping component and a posture adjustment assembly. The posture adjustment assembly can adjust the posture of the scraping component, so that the scraping component is in an inclined scraping position or a horizontal scraping position relative to the moving direction of the scraping cleaning device. When it is in the inclined scraping position, the first end is always in front of the second end in the moving direction. As a result, when the scraping cleaning device moves along the first direction to scrape the surface to be cleaned, water stains are always gathered to one side. Similarly, when the scraping cleaning device moves along the second direction to wipe the surface to be cleaned, the scraping component switches to the horizontal scraping position. At this time, water stains move with the scraping component and gather, without causing secondary pollution to the cleaned area. Users do not need to wipe repeatedly, thereby improving the cleaning efficiency of the scraping cleaning device and thus improving the user experience. By alternating between tilted and horizontal scraping positions—that is, switching from tilted to horizontal and then back to tilted—the angle of the scraper does not need to change too much during the switching process. This effectively achieves the combined benefits of effective scraping and cleaning without causing secondary contamination to the already cleaned area. It also saves time when switching between tilted and horizontal scraping positions, and because the angle change of the scraper is small, the switching is relatively effortless and efficient.

[0008] In one possible design, when the scraping cleaning device moves in a first direction to scrape the surface to be cleaned, the posture adjustment component is used to adjust and hold the scraper in an inclined scraping position; when the scraping cleaning device moves in a second direction to scrape the surface to be cleaned, the posture adjustment component is used to adjust and hold the scraper in a horizontal scraping position, the first direction and the second direction being opposite.

[0009] In one possible design, when the scraping member is in the inclined scraping position, the angle between the first end and the direction of movement is α1, where 5°≤α1≤60°.

[0010] In one possible design, the attitude adjustment component is used to drive the body to deflect, thereby driving the scraping member to deflect, so that the scraping member is in the inclined scraping position or the horizontal scraping position relative to the direction of movement.

[0011] In one possible design, the scraping cleaning device further includes a push-pull rod connected to the body via the attitude adjustment component.

[0012] In one possible design, the attitude adjustment assembly includes a fixed member, a swing member, and a limiting member; the fixed member is fixedly connected to the push-pull rod, and the swing member is connected to the body; the swing member is hinged to the fixed member, and the swing of the swing member drives the scraping member to deflect; the limiting member is used to limit the swing of the swing member.

[0013] In one possible design, under the action of friction between the scraping cleaning device and the surface to be cleaned, the swinging member is held on the fixing member by the limiting member, thereby keeping the scraping member in the inclined scraping position or the horizontal scraping position.

[0014] In one possible design, when the moving direction of the scraping cleaning device switches between the first direction and the second direction, the oscillating member is deflected under the action of the friction between the scraping cleaning device and the surface to be cleaned.

[0015] In one possible design, the posture adjustment component further includes a power element, under the action of the power element, when the movement direction of the scraping cleaning device switches between the first direction and the second direction, the swinging member is deflected.

[0016] In one possible design, the power component includes a push rod for pushing the oscillating component to oscillate.

[0017] In one possible design, both the fixing element and the swinging element are plate-shaped structures.

[0018] In one possible design, the limiting member includes an arc-shaped groove and a sliding pin that cooperate with each other; the arc-shaped groove is formed on one of the fixing member and the swinging member; the sliding pin is disposed on the other of the fixing member and the swinging member.

[0019] In one possible design, the limiting element is a blocking block.

[0020] In one possible design, the fixed member and the swing member are hinged to each other via a pivot.

[0021] In one possible design, the fixed component is provided with a first gear structure, and the swing component is provided with a second gear structure, with the first gear structure and the second gear structure meshing with each other. This allows the swing of the swing component to be more stable and controllable.

[0022] In one possible design, the fixed member and the swing member are hinged to each other via a swing arm.

[0023] In one possible design, the fixing member has a U-shaped structure, and the swing member is hinged within the cavity of the U-shaped structure. This allows for better limiting of the swing member.

[0024] In one possible design, the attitude adjustment assembly includes a U-shaped bracket connected to the push-pull rod. One end of the U-shaped bracket is hinged to a through hole in the side wall of the body via a first rotating pin, allowing the body to swing relative to the first rotating pin. The other end of the U-shaped bracket is slidably disposed in a strip groove in the other side wall of the body via a second rotating pin.

[0025] In one possible design, the scraping element is movably connected to the body, and the attitude adjustment component drives the scraping element to deflect relative to the body, thereby placing the scraping element in the tilted scraping position or the horizontal scraping position relative to the direction of movement.

[0026] In one possible design, the scraping cleaning device further includes a drive assembly, and the scraping element includes a first scraping element and a second scraping element, which are respectively disposed on opposite sides of the body.

[0027] In one possible design, when the scraping cleaning device reciprocates to scrape the surface to be cleaned, the drive assembly drives the scraper located on the front side of the movement direction away from the surface to be cleaned and stops it from working, and drives the scraper located on the rear side of the movement direction closer to the surface to be cleaned to perform the scraping work.

[0028] To achieve better cleaning results, a wiping material is usually placed in the middle of the contact surface between the body of the scraping cleaning device and the surface to be cleaned. This arrangement ensures that the scraping cleaning device scrapes and cleans the surface to be cleaned in the direction of the wiping material in front and the scraping part behind, thereby achieving the technical effect of "wiping before scraping" and improving the cleaning efficiency of the scraping cleaning device.

[0029] In a second aspect, a scraping cleaning assembly is provided, including a first scraping cleaning device and a second scraping cleaning device that are magnetically attracted to each other, wherein the first scraping cleaning device is a scraping cleaning device provided by any possible design of the aforementioned first aspect.

[0039] The technical solutions of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them.

Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0044] Firstly, this application provides a scraping and cleaning device, which can be the aforementioned glass wiper, capable of scraping and cleaning glass surfaces. Furthermore, this scraping and cleaning device can also be used to scrape and clean other surfaces such as desktops, walls, floors, and blackboards; this application does not limit its application to this.

[0045] Figure 1 This is a schematic diagram illustrating the working principle of the scraping cleaning device provided in this application embodiment. Figure 1 (a) is a schematic diagram of the principle of the scraping cleaning device moving in the first direction A1. Figure 1 (b) is a schematic diagram illustrating the principle of the scraping cleaning device moving in the second direction A2. For example... Figure 1 As shown, the scraping cleaning device provided in this application embodiment includes: a scraping component 10 and a posture adjustment component 20.

[0046] The scraping component 10 is connected to the body of the scraping cleaning device. Figure 1 (Not shown in the middle)

[0047] The attitude adjustment component 20 is used to adjust the attitude of the scraper 10 so that when the scraping cleaning device moves along the first direction A1 to scrape the surface to be cleaned, the scraper 10 is always in an inclined position relative to the moving direction, i.e., an inclined scraping position. The so-called inclination of the scraper 10 means that the first end 11 of the scraper 10 is always in front of the second end 12 in the moving direction. When the scraping cleaning device moves along the second direction A2 to scrape the surface to be cleaned, it is in a horizontal scraping position. Here, the so-called horizontal scraping position of the scraper 10 means that the line connecting the first end 11 and the second end 12 of the scraper 10 is approximately perpendicular to the second direction, that is, the length direction of the scraper 10 is approximately perpendicular to the second direction. The "approximately perpendicular" mentioned in this application includes the state in which the length direction of the scraper 10 is nearly completely perpendicular to the second direction and the state in which the length direction of the scraper 10 is completely perpendicular to the second direction.

[0048] Wherein, the first end 11 is one end of the scraper 10 along the length direction, and the second end 12 is the other end of the scraper 10 along the length direction.

[0049] The scraping cleaning device provided in this application includes a scraper 10, which is connected to the body of the scraping cleaning device. When the scraping cleaning device moves on the surface to be cleaned (e.g., a glass surface), the scraper 10 can scrape the surface to be cleaned, thereby cleaning the surface. When the scraping cleaning device reciprocates on the surface to be cleaned, the scraper 10 can also continuously and reciprocate scraping the surface to be cleaned.

[0050] like Figure 1 As shown, the scraping cleaning device provided in this application embodiment also includes a posture adjustment component 20, which is connected to the scraper 10 for adjusting the posture of the scraper 10. That is, when the scraper 10 moves along the first direction A1, the posture adjustment component 20 adjusts the scraper 10 so that the scraper 10 is always in an inclined scraping position relative to the moving direction. In other words, the first end 11 of the scraper 10 is always in front of the second end 12 in the moving direction. When the scraper 10 moves along the second direction A2, the posture adjustment component 20 adjusts the scraper 10 so that the scraper 10 is always in a horizontal scraping position.

[0051] Specifically, when the scraping cleaning device performs a scraping action from left to right and moves along the first direction A1 (in this embodiment, the first direction A1 is the upward direction) to scrape the surface to be cleaned, the attitude adjustment component 20 adjusts the attitude of the scraping member 10 so that the scraping member 10 is in an inclined scraping position relative to the moving direction, and the first end 11 of the scraping member 10 is located in front of the second end 12 in the moving direction. At this time, since the scraping member 10 is in an inclined scraping position and the first end 11 is located in front of the second end 12, the scraped water stains will be gathered (converged, guided) from the first end 11 to the second end 12, thus preventing secondary pollution to the cleaned area.

[0052] In other words, when the scraping cleaning device moves in the first direction A1 to scrape the surface to be cleaned, the scraping member 10 can deflect water stains towards... Figure 1 The particles converge on the right side of the surface, allowing users to clean the surface from left to right. Figure 1 The right side of the central scraping cleaning device is the area that has not yet been cleaned, and the left side is the area that has been cleaned. Water stains are drawn to the right by the scraping part 10 and will not contaminate the cleaned area on the left.

[0053] After the scraping cleaning device is moved upward to the stop position, it shifts to the right and then moves along the second direction A2 (in this embodiment, the second direction A2 is downward) to scrape the surface to be cleaned. The second direction A2 is opposite to the first direction A1. The attitude adjustment component 20 then adjusts the attitude of the scraping member 10 so that the scraping member 10 is basically in a horizontal position, that is, the line connecting the first end 11 and the second end 12 of the scraping member 10 is basically in a horizontal position, meaning that the length direction of the scraping member 10 is approximately perpendicular to the second direction A2. At this time, since the scraper 10 is in a horizontal scraping position, and given that the water stains are moving downwards due to gravity, and the scraper 10 also causes the water stains to move downwards, and since the water stains are close to the second end 12 of the scraper 10, under the downward driving force of the scraper 10 and the downward force of the water stains themselves, when the scraper 10 reaches the stop position along the second direction A2, the water stains that are guided downwards will not be guided to the cleaned area on the left, and thus will not cause secondary pollution to the cleaned area.

[0054] It is particularly noteworthy that by alternating between the tilted and horizontal scraping positions—that is, switching from the tilted scraping position to the horizontal scraping position and then back to the tilted scraping position—the angle change of the scraper 10 does not need to be too large during the switching process. This effectively achieves the switching between the two positions, enabling comprehensive and beneficial technical effects such as effective scraping and cleaning without causing secondary pollution to the already cleaned area. Furthermore, it saves time when switching between the tilted and horizontal scraping positions, and because the angle change of the scraper 10 is small, the switching is relatively effortless and efficient.

[0055] The scraping cleaning device provided in this application includes a scraper 10 and a posture adjustment component 20. The posture adjustment component 20 can adjust the posture of the scraper 10 so that when the scraper 10 moves in the first direction A1, it is always in an inclined scraping position, and the first end 11 is always located in front of the second end 12 in the moving direction. When the scraper 10 moves in the second direction A2, it is always in a horizontal scraping position, and the length direction of the scraper 10 is approximately perpendicular to the second direction A2.

[0056] This ensures that during the reciprocating motion of the scraping cleaning device to scrape the surface to be cleaned, water stains are always drawn to the same side in one direction, while in the opposite direction, water stains are always moved together by the scraping component 10, without causing secondary pollution to the already cleaned area. Users do not need to wipe repeatedly, thus improving the cleaning efficiency of the scraping cleaning device and enhancing the user experience.

[0057] In this embodiment, the scraping cleaning device moves back and forth to scrape the surface to be cleaned. This can be done manually by the user to wipe the surface, or by an internal motor driving the scraping cleaning device to move and scrape the surface. This application does not limit the scope of the invention.

[0058] Optionally, the scraping cleaning device may include a push-pull rod, which allows the user to move the main body of the scraping cleaning device back and forth, thereby achieving scraping and cleaning of the surface to be cleaned.

[0059] Optionally, the scraping cleaning device also includes a walking component, which includes a walking motor and walking wheels, thereby enabling the scraping cleaning device to move automatically without human intervention.

[0060] Alternatively, the wiping and cleaning device can be a glass cleaning robot, which, in addition to the aforementioned walking components, also includes sensors and an intelligent control system, such as the ability to plan the wiping route.

[0061] In the embodiments of this application, the scraping cleaning device can be used to scrape and clean surfaces such as glass surfaces, desktops, walls, floors, and blackboards. That is to say, the surface to be cleaned can be any one of glass surfaces, desktops, walls, floors, blackboards, etc., and this application does not limit it.

[0062] In the embodiments of this application, the scraping cleaning device reciprocates in a first direction A1 and a second direction A2, where the first direction A1 and the second direction A2 are any two opposite directions, and this application does not limit them.

[0063] For example, the first direction A1 can be upward and the second direction A2 can be downward. Alternatively, the first direction A1 can be downward and the second direction A2 can be upward.

[0064] Optionally, the user can drive the scraping cleaning device to reciprocate in the first direction A1 and the second direction A2, where the first direction A1 can be in front of the user and the second direction A2 can be behind the user.

[0065] like Figure 1 As shown in the embodiment of this application, the first end 11 of the scraper 10 is the left end of the scraper 10 in the moving direction, and the second end 12 of the scraper 10 is the right end of the scraper 10 in the moving direction. When the scraper 10 moves along the first direction A1, the water stains are gathered to the right, and the user can clean the surface to be cleaned in order from left to right.

[0066] In other embodiments, the first end 11 and the second end 12 can be interchanged. In this case, the first end 11 of the scraper 10 is the right end of the scraper 10 in the moving direction, and the second end 12 of the scraper 10 is the left end of the scraper 10 in the moving direction. At this time, water stains are gathered to the left, and the user can clean the surface to be cleaned in the order from right to left.

[0067] This application does not limit the specific structure of the scraping component 10. For example, the scraping component 10 can be any of the following devices that can perform scraping operations: scraper, scraper, cleaning brush, rag, mop head, etc.

[0068] In this embodiment, the scraping element 10 can be a scraper strip.

[0069] Alternatively, the scraper can be made of plastic or rubber.

[0070] Optionally, the scraping element 10 may consist of multiple scraper strips (or scrapers, cleaning brushes, etc.). For example, the multiple scraper strips may be connected one after another or parallel to each other to form the scraping element 10.

[0071] Alternatively, the scraping cleaning device can also be a mop. In this case, the scraping element 10 can be a mop head.

[0072] In this embodiment, the scraper 10 is connected to the body of the scraping cleaning device. The scraper 10 can be fixedly connected to the body or movably connected to the body. This application does not limit this.

[0073] Optionally, the scraper 10 can be movably connected to the body. In this case, the body can remain stationary, and the attitude adjustment component 20 can drive the scraper 10 to deflect relative to the body, thereby causing the scraper 10 to be in an inclined scraping position or a horizontal scraping position relative to the direction of movement.

[0074] Optionally, the attitude adjustment component 20 can also drive the main body to deflect, thereby driving the scraping component 10 to deflect as well, so that the scraping component 10 is in the inclined scraping position or the horizontal scraping position relative to the direction of movement. In this case, the scraping component 10 can be fixedly connected to the main body or movably connected to the main body, and this application does not limit this.

[0075] For example, the scraper 10 can be movably connected to the body, such as the scraper 10 being able to extend or retract into the body.

[0076] Furthermore, the scraping cleaning device also includes a drive assembly ( Figure 1 (Not shown in the image), the scraping member 10 includes a first scraping member and a second scraping member, which are respectively disposed on opposite sides of the body. When the scraping cleaning device reciprocates to scrape the surface to be cleaned, the drive assembly drives the scraping member 10 located on the front side of the movement direction away from the surface to be cleaned and stops working, and drives the scraping member 10 located on the rear side of the movement direction closer to the surface to be cleaned to perform scraping work.

[0077] To achieve better cleaning results, a wiping material is usually provided in the middle of the contact surface between the body of the scraping cleaning device and the surface to be cleaned. With the above arrangement, it can be ensured that the scraping cleaning device scrapes and cleans the surface to be cleaned in the direction of the wiping material in front and the scraping part 10 behind, thereby achieving the technical effect of "wiping before scraping" and improving the cleaning efficiency of the scraping cleaning device.

[0078] This application does not limit the specific form of the driving component, as long as it can enable the first and second scraping components to switch between working and non-working states. For details on the specific settings of the driving component, please refer to the applicant's earlier patent applications with numbers 202010670650.2 and 202021375474.1, etc., which will not be repeated here.

[0079] In the embodiments of this application, the attitude adjustment component 20 is connected to the scraper 10 in a transmission manner, thereby enabling the attitude of the scraper 10 to be adjusted. This application does not limit the specific composition of the attitude adjustment component 20 or the form in which the attitude of the scraper 10 is adjusted.

[0080] Optionally, the posture of the scraper 10 can be adjusted manually by the user through the posture adjustment component 20.

[0081] Alternatively, the attitude of the scraper 10 can be adjusted by an electric device (e.g., a motor) via the attitude adjustment assembly 20.

[0082] Optionally, the attitude adjustment component 20 can adjust the attitude of the scraper 10 by swinging the scraper 10.

[0083] In this embodiment of the application, when the scraping cleaning device reciprocates to scrape the surface to be cleaned, the scraping member 10 is always in an inclined scraping position relative to the first direction A1 of the moving direction. This means that the scraping cleaning device is always in an inclined scraping position relative to the moving direction when it reciprocates.

[0084] For example, when the scraping cleaning device moves along the first direction A1 to scrape the surface to be cleaned, the attitude adjustment component 20 adjusts the attitude of the scraping member 10 so that the scraping member 10 is in an inclined scraping position relative to the direction of movement. When the scraping cleaning device moves in the direction A2 to scrape the surface to be cleaned, the attitude adjustment component 20 adjusts the attitude of the scraping member 10 again so that the scraping member 10 is in a horizontal scraping position.

[0085] Here, the inclined scraping position is a relative position relative to the direction of movement of the scraping cleaning device, and it is an angular position. In the inclined scraping position, the scraper 10 is inclined relative to the direction of movement, and the scraper 10 is neither perpendicular nor parallel to the direction of movement. Conversely, the horizontal scraping position is horizontally arranged relative to the inclined scraping position, and the length direction of the scraper 10 (that is, the extension direction of the scraper 10) is approximately perpendicular to the direction of movement.

[0086] It is worth mentioning that the tilted scraping position may not be a fixed position (angle). For example, the tilted scraping position can change during the movement of the scraping cleaning device (i.e., the scraper 10 can swing), as long as the scraper 10 is always tilted relative to the direction of movement, and the first end 11 is always in front of the second end 12 in the direction of movement. In this case, the scraper 10 can still push and gather water stains to the same side.

[0087] like Figure 1As shown in diagram a, when the scraping cleaning device moves in the first direction A1, the attitude adjustment component 20 controls the angle α1 between the first end 11 and the direction of movement. During the movement, the scraping member 10 can swing to a certain extent, so that the size of the angle α1 can change, for example, α1 can change between 5 and 60 degrees. It is easy to understand that even if the scraping member 10 swings to a certain extent, since the first end 11 is always located in front of the second end 12, the scraping member 10 will always push the water stains to the right and make them converge.

[0088] Similarly, such as Figure 1 As shown in b, when the scraping cleaning device moves in the second direction A2, the attitude adjustment component 20 controls the length direction of the scraping component 10 to be approximately perpendicular to the moving direction. During the movement, the scraping component 10 can also swing to a certain extent, that is, the scraping component 10 swings until its length direction and the moving direction are approximately perpendicular to each other.

[0089] Optionally, when the scraping cleaning device moves in the first direction A1 to scrape the surface to be cleaned, the attitude adjustment component 20 can also adjust and hold the scraper 10 in an inclined scraping position. At this time, the attitude adjustment component 20 controls the angle α1 between the first end 11 and the moving direction to remain unchanged, that is, α1 is a constant value. When the scraping cleaning device moves in the second direction A2 to scrape the surface to be cleaned, the attitude adjustment component 20 can adjust and hold the scraper 10 in a horizontal scraping position. At this time, the attitude adjustment component 20 controls the length direction of the scraper 10 to remain approximately perpendicular to the second direction A2.

[0090] Optionally, in order to ensure the water stains converge and prevent them from flowing to the left side of the scraper 10, when the scraper 10 is in the tilted scraping position, the angle α1 between the first end 11 and the direction of movement is in the range of 5°≤α1≤60°. For example, α1 can be 15°, 30°, 45°, 55°, etc.

[0091] When the scraping member 10 is in the horizontal scraping position, the scraping member 10 is basically perpendicular to the second direction A2.

[0092] The scraping and cleaning device provided in the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0093] For ease of description and understanding, the following description will use a glass surface as the surface to be cleaned to further illustrate the scraping cleaning device provided in this application. That is, the scraping cleaning device in the following description can be understood as a glass wiper. Based on this, the first direction A1 in the following description can be understood as upward, and the second direction A2 can be understood as downward, and vice versa.

[0094] Figure 2 This is a schematic diagram of the working state of an example of the scraping cleaning device provided in this application embodiment. Wherein, Figure 2 (a) is a schematic diagram of the state in which the scraping cleaning device moves in the first direction A1. Figure 2 (b) is a schematic diagram of the state in which the scraping cleaning device moves in the second direction A2.

[0095] like Figure 2 As shown, in this embodiment, the attitude adjustment component 20 is used to drive the body 30 to deflect, thereby driving the scraper 10 to deflect as well, so that the scraper 10 is in an inclined scraping position or a horizontal scraping position relative to the direction of movement. Optionally, the scraper 10 can be fixed to the body 30 at this time.

[0096] Furthermore, the scraping cleaning device also includes a push-pull rod 40, which is connected to the main body 30 via a posture adjustment component 20. In this case, the posture adjustment component 20 can transmit power to the push-pull rod 40, enabling the scraping cleaning device to move, and can also adjust and hold the scraping component 10 in an inclined or horizontal scraping position.

[0097] For example, a user can hold the push-pull rod 40 and push the main body 30 upward through the push-pull rod 40 and the posture adjustment component 20 to scrape and clean the glass surface upward. At this time, the posture adjustment component 20 keeps the scraper 10 in an inclined scraping position, and the scraped water stains are gathered to the right.

[0098] When the scraping cleaning device is moved to the upper stop position, the user can move the main body 30 to the right to a certain extent. Then, the user can pull the main body 30 downwards using the push-pull rod 40 and the attitude adjustment component 20, thereby scraping and cleaning the glass surface downwards. At this time, the attitude adjustment component 20 keeps the scraping element 10 in a horizontal scraping position, and the scraped water stains are carried by the scraping element 10 to collect at the bottom of the glass window. Until the scraping cleaning device is moved to the lower stop position, the user can again move the main body 30 to the right to a certain extent, and then continue to push the main body 30 upwards using the push-pull rod 40, thereby realizing the reciprocating movement of the main body 30 on the glass surface, thus achieving continuous cleaning of the glass surface.

[0099] Optionally, to improve practicality, the push-pull rod 40 can be a telescopic rod, and the end of the push-pull rod 40 can also be provided with a handle for easy gripping by the user.

[0100] The following will be combined with the appendix Figure 2 The attitude adjustment component 20 provided in the embodiments of this application will be further described.

[0101] like Figure 2As shown, the posture adjustment component 20 provided in this application embodiment includes a fixing component 21, a swinging component 22, and a limiting component 23.

[0102] Among them, the fixing member 21 is fixedly connected to the push-pull rod 40, and the swing member 22 is connected to the body 30.

[0103] Alternatively, the fastener 21 and the push-pull rod 40 can be integrally molded using processes such as injection molding.

[0104] Optionally, the swing element 22 is fixedly connected to or hinged to the body 30.

[0105] For example, the swing member 22 can be hinged to the opposite sides of the body 30 via a U-shaped connecting arm 22a. In this case, hinge holes can be opened on the opposite sides of the body 30, and a hinge shaft is fixed on the side wall of the connecting arm 22a facing the body 30, which is rotatably connected in the hinge hole.

[0106] Furthermore, the swing member 22 is hinged to the fixed member 21, and the swing member 22 can swing relative to the fixed member 21. The swing of the swing member 22 can drive the body 30 to deflect, thereby driving the scraping member 10 to deflect.

[0107] In this embodiment, both the fixing member 21 and the swing member 22 are plate-shaped structures and are hinged to each other via the pivot 25.

[0108] Optionally, the pivot 25 can be any one of a pin, rivet, screw, bolt, etc.

[0109] Figure 3 This is a side view of the fastener 21 provided in an embodiment of this application. Figure 3 As shown, the fixing member 21 has an overall U-shaped structure, and the swing member 22 is hinged to the cavity of the U-shaped structure. At this time, the fixing member 21 includes three parts, namely the base plate 21a and two side plates 21b connected to both sides of the base plate 21a. The swing member 22 can be clamped between the two side plates 21b, thereby providing a better limiting effect for the swing member 22.

[0110] At this time, the rotating shaft 25 can pass through the two side plates 21b and the swing member 22, so that the swing member 22 is hinged in the cavity of the U-shaped structure, and the swing member 22 can swing in the cavity.

[0111] The limiting member 23 is used to limit the swing of the swing member 22, so that the swing member 22 can swing between two extreme positions. When the swing member 22 is swung to one extreme position, the swing member 22 drives the scraper 10 to be adjusted to the inclined scraping position through the body 30. When the swing member 22 is swung to the other extreme position, the swing member 22 drives the scraper 10 to be adjusted to the horizontal scraping position through the body 30.

[0112] This application does not limit the specific structure of the limiting member 23, as long as it can limit the swing of the swing member 22.

[0113] like Figure 2 As shown in the embodiment of this application, the limiting member 23 includes an arc-shaped groove 23a and a sliding pin 23b that cooperate with each other. The arc-shaped groove 23a is formed on the swing member 22, and the sliding pin 23b is correspondingly disposed on the side of the fixing member 21 facing the swing member 22. The rear end of the sliding pin 23b is fixedly connected to the fixing member 21, and the front end is slidably disposed in the arc-shaped groove 23a.

[0114] One end of the arc-shaped groove 23a is the first limiting end (i.e. Figure 2 At the upper end of the arc-shaped groove 23a, when the swinging member 22 is swung and the sliding pin 23b abuts against the first limiting end, the scraping member 10 is adjusted to the inclined scraping position. The other end of the arc-shaped groove 23a is the second limiting end (i.e., Figure 2 When the swing member 22 is swung and the sliding pin 23b abuts against the second limiting end, the scraping member 10 is adjusted to a horizontal scraping position.

[0115] In this embodiment, the scraper 10 can be adjusted and maintained in the inclined scraping position or the horizontal scraping position by the friction between the scraping cleaning device and the glass surface.

[0116] Under the action of friction between the scraping cleaning device and the glass surface, the swinging member 22 is held on the fixed member 21 by the limiting member 23, thereby keeping the scraping member 10 in an inclined scraping position or a horizontal scraping position.

[0117] Specifically, such as Figure 2 As shown in Figure a, when the user pushes the main body 30 upward on the glass surface using the push-pull rod 40, friction is generated between the main body 30 and the glass surface. More specifically, at this time, the main body 30 is subjected to downward friction. Under the action of this friction, the swinging member 22 swings downward relative to the fixed member 21, causing the first limiting end of the arc-shaped slide groove 23a to abut against the sliding pin 23b. The swinging member 22 is held on the fixed member 21 by the limiting member 23. The swinging member 22 holds the scraping member 10 in an inclined scraping position through the main body 30, thereby causing the scraped water stains to converge to the right.

[0118] like Figure 2As shown in b, when the main body 30 moves upward to the upper stop position on the glass surface, the user stops pushing the main body 30 and pulls the main body 30 downward through the push-pull rod 40, thereby changing the direction of movement of the main body 30. At this time, when the user pulls the main body 30 downward on the glass surface through the push-pull rod 40, friction is generated between the main body 30 and the glass surface. More specifically, the main body 30 is subjected to an upward friction force. Under the action of this friction force, the swinging member 22 swings upward relative to the fixed member 21, so that the second limiting end of the arc-shaped slide groove 23a abuts against the slide pin 23b. The swinging member 22 is held on the fixed member 21 by the limiting member 23. The swinging member 22 holds the scraping member 10 in a horizontal scraping position through the main body 30. In this horizontal scraping position, the length direction of the scraping member 10 is approximately perpendicular to the vertical downward direction, thereby causing the scraped water stains to flow and converge vertically downward.

[0119] In other words, when the movement direction of the scraping cleaning device switches between the up and down directions, the swing member 22 can be deflected under the action of the friction between the scraping cleaning device and the glass surface, and further keep the scraping member 10 in the inclined scraping position or the horizontal scraping position.

[0120] Optionally, in other embodiments, the positions of the arc-shaped groove 23a and the sliding pin 23b can be interchanged. In this case, the arc-shaped groove 23a can be formed on the fixing member 21, and the sliding pin 23b is correspondingly disposed on the side of the swing member 22. The rear end of the sliding pin 23b is fixedly connected to the swing member 22, and the front end is slidably disposed within the arc-shaped groove 23a. Similar technical effects can be achieved through the above arrangement, which will not be elaborated further in this application.

[0121] Figure 4 This is a schematic diagram of the working state of another example of the scraping cleaning device provided in this application embodiment. Wherein, Figure 4 (a) is a schematic diagram of the state in which the scraping cleaning device moves in the first direction A1. Figure 4 (b) is a schematic diagram of the state in which the scraping cleaning device moves in the second direction A2.

[0122] Considering that the friction between the scraping cleaning device and the surface to be cleaned may be relatively small, insufficient to cause the oscillating member 22 to deflect, relative to the aforementioned Figure 2 In the embodiment shown, the posture adjustment component 20 further includes a power component 24. When the moving direction of the scraping cleaning device switches between the first direction A1 and the second direction A2, the swing component 22 is deflected under the action of the power component 24.

[0123] The power component 24 can drive the swing component 22 to swing between two extreme positions, thereby enabling the scraping component 10 to switch between an inclined scraping position and a horizontal scraping position. This application does not limit the specific structure of the power component 24 or how it drives the swing component 22 to swing, as long as the above-mentioned function can be achieved.

[0124] like Figure 4 As shown in the embodiment of this application, the power component 24 includes a push rod 24a; the push rod 24a is used to push the swing component 22 to swing.

[0125] Furthermore, the power component 24 also includes a push-pull handle 24c. The push rod 24a is movably disposed inside the push-pull rod 40, and the push-pull handle 24c passes through the push-pull rod 40 and is fixedly connected to the push rod 24a. The push-pull rod 40 has a sliding groove, and the push-pull handle 24c can move back and forth in the sliding groove. By pushing the push-pull handle 24c, the user can drive the push rod 24a to move upward, thereby pushing the swing member 22, so that the swing member 22 can swing upward.

[0126] Furthermore, the power component 24 also includes a return spring 24b, which is also disposed inside the push-pull rod 40 and sleeved on the outer periphery of the push rod 24a. When the force applied by the user to the push rod 24a disappears, the push rod 24a can be reset by the return spring 24b.

[0127] In this embodiment, the limiting member 23 is a stop block 23c, which is used to limit the swing member 22 to an extreme position so as to limit the scraping member 10 to the inclined scraping position.

[0128] Optionally, in order to improve the degree of automation and thus improve the user experience, an electric device such as a motor can be set to drive the push rod 24a to push the swing member 22. In this case, a corresponding control button can be set on the outer wall of the push rod 40 to control the operation of the electric device.

[0129] like Figure 4 As shown, the stop block 23c can be fixedly installed on the inner side wall of the side plate 21b of the fixing member 21. The stop block 23c can abut against the swing member 22, thereby limiting the swing member 22.

[0130] like Figure 4 As shown, in this embodiment, the stop block 23c can be disposed on the inner wall surface of the base plate 21a.

[0131] Figure 5 This is a schematic diagram of the working state of another example of the scraping cleaning device provided in the embodiments of this application. Wherein, Figure 5 (a) is a schematic diagram of the state in which the scraping cleaning device moves in the first direction A1. Figure 5 (b) is a schematic diagram of the state in which the scraping cleaning device moves in the second direction A2.

[0132] Compared to the above Figure 2 , 4 In the illustrated embodiment, the fixed member 21 is provided with a first gear structure 26a, and the swing member 22 is provided with a second gear structure 26b. The first gear structure 26a and the second gear structure 26b mesh with each other. By providing the meshing first gear structure 26a and the second gear structure 26b, the swing of the swing member 22 can be made more stable and controllable.

[0133] like Figure 5 As shown, the first gear structure 26a can be rotatably connected to the inner side wall of the side plate 21b, and the second gear structure 26b can be formed on the side wall of the swing member 22. The first gear structure 26a serves as a support wheel and meshes with the second gear structure 26b.

[0134] Optionally, the swing member 22 can be formed with a hollow structure, thereby reducing the weight of the swing member 22 and facilitating swinging.

[0135] In this embodiment, the limiting member 23 is a stop 23c, which is used to keep the swing member 22 in the inclined scraping position. By adjusting the position of the stop 23c and the shape of the swing member 22, the tilt angle of the swing member 22 can be limited.

[0136] like Figure 5 As shown in Figure a, when the user pushes the main body 30 upward on the glass surface using the push-pull rod 40, a downward frictional force is generated between the scraping cleaning device and the glass surface. That is, the main body 30 is subjected to a downward frictional force at this time. Under the action of this frictional force, the swinging member 22 swings downward relative to the fixed member 21, so that the swinging member 22 abuts against the stop block 23c. The swinging member 22 is held on the fixed member 21 by the stop block 23c. The swinging member 22 holds the scraping member 10 in an inclined scraping position through the main body 30, thereby causing the scraped water stains to converge to the right.

[0137] like Figure 5As shown in Figure b, when the main body 30 moves upward to the upper stop position on the glass surface, the user stops pushing the main body 30 and pulls the main body 30 downward through the push-pull rod 40, thereby changing the direction of movement of the main body 30. At this time, when the user pulls the main body 30 downward on the glass surface through the push-pull rod 40, an upward frictional force is generated between the scraping cleaning device and the glass surface. That is to say, the main body 30 is subjected to an upward frictional force. Under the action of this frictional force, the swinging member 22 swings upward relative to the fixed member 21. The swinging member 22 drives the main body 30 so that the length direction of the scraping member 10 reaches a position that is approximately perpendicular to the downward direction. Under the continuous pulling action of the push-pull rod 40, the scraping member 10 always remains in a horizontal scraping position, thereby causing the scraped water stains to converge towards the lower part of the glass window.

[0138] During the swinging process, the first gear structure 26a rotates relative to the fixed member 21 and meshes with the second gear structure 26b, thereby making the swinging of the swinging member 22 more stable and controllable.

[0139] Figure 6 This is a schematic diagram of the working state of another example of the scraping cleaning device provided in the embodiments of this application. Wherein, Figure 6 (a) is a schematic diagram of the state in which the scraping cleaning device moves in the first direction A1. Figure 6 (b) is a schematic diagram of the state in which the scraping cleaning device moves in the second direction A2.

[0140] Compared to the above Figure 2 , 4 In the embodiment shown in Figure 5, the fixed member 21 and the swing member 22 are hinged to each other by the swing rod 27.

[0141] Specifically, one end of the swing arm 27 is rotatably connected to the fixed member 21 via a pivot, and the other end of the swing arm 27 is rotatably connected to the swing member 22 via a pivot, thereby making the fixed member 21 and the swing member 22 hinged to each other.

[0142] At this time, the stop block 23c can be fixedly set on one side of the swing arm 27, thereby limiting the swing member 22 and thus limiting the scraping member 10 to the inclined scraping position.

[0143] Optionally, in this embodiment, there are two parallel swing arms 27. In other embodiments, there may be one, three or more swing arms 27. This application does not limit this.

[0144] Figure 7 This is a schematic diagram of another example of the scraping and cleaning device provided in the embodiments of this application. Figure 8 yes Figure 7 The diagram shows the structure of the main body 30 in the scraping cleaning device.

[0145] like Figure 7 and Figure 8 As shown, in this embodiment, the attitude adjustment assembly 20 includes a U-shaped bracket 28 fixedly connected to the push-pull rod 40. One end of the U-shaped bracket 28 is hinged to a through hole in the side wall of the body 30 via a first rotating pin, allowing the body 30 to swing relative to the first rotating pin. The other end of the U-shaped bracket 28 is slidably disposed in a strip groove 33 on the other side wall of the body 30 via a second rotating pin 29.

[0146] When the user pushes the body 30 upward on the glass surface using the push-pull rod 40, the body 30 experiences a downward frictional force. Under the action of this frictional force, the right end of the body 30 swings downward relative to the left end, causing the limiting end of the strip groove 33 on the front side (i.e., Figure 8 The upper end of the middle strip groove 33 abuts against the second rotating pin 29. At this time, the body 30 holds the scraper 10 in an inclined scraping position, so that the scraped water stains are gathered to the right.

[0147] When the body 30 moves upward to the upper stop position on the glass surface, the user stops pushing the body 30 and pulls the body 30 downward through the push-pull rod 40, thereby changing the direction of movement of the body 30. At this time, when the user pulls the body 30 downward on the glass surface through the push-pull rod 40, the body 30 is subjected to an upward frictional force. Under the action of this frictional force, the right end of the body 30 swings upward relative to the left end, causing the limiting end of the strip groove 33 on the front side (i.e., the limit end) in the direction of movement to be stopped. Figure 8 The lower end of the middle strip groove 33 abuts against the second rotating pin 29. At this time, the body 30 keeps the scraper 10 in a horizontal scraping position, so that the scraped water stains are gathered towards the lower part of the glass window.

[0148] like Figure 7 , 8 As shown, a magnetic adjustment knob 31 is also provided on the top cover of the main body 30. By rotating the magnetic adjustment knob 31, the strength of the magnetic field of the scraping cleaning device can be changed.

[0149] like Figure 8 As shown, in this embodiment, the scraping member 10 includes two parts, which are respectively disposed on opposite sides of the body 30.

[0150] Furthermore, the two scraping elements 10 are fixed and do not switch. However, a preferred solution is that the two scraping elements 10 switch. Specifically, a drive component can also be provided within the main body 30. When the scraping cleaning device reciprocates to scrape the glass surface, the drive component drives the scraping element 10 located in the forward direction of movement away from the glass surface and stops working, while driving the scraping element 10 located in the rear direction of movement closer to the glass surface to perform scraping work.

[0151] To achieve better cleaning results, a wiping material is usually provided in the middle of the contact surface between the body 30 of the scraping cleaning device and the glass surface. With the above arrangement, it can be ensured that the scraping cleaning device scrapes and cleans the surface to be cleaned in the direction of the wiping material in front and the scraping part 10 behind, thereby achieving the technical effect of "wiping before scraping" and improving the cleaning efficiency of the scraping cleaning device.

[0152] For example, when the scraping cleaning device... Figure 7 When the upper part moves to scrape the glass surface, the drive component drives the position located in Figure 7 The upper middle scraper 10 is away from the glass surface and does not operate, while the drive is located at... Figure 7 The lower center scraper 10 is close to the glass surface to perform scraping work.

[0153] For example, when the scraping cleaning device moves towards... Figure 7 When the lower part moves to scrape the glass surface, the drive component drives the position located in Figure 7 The lower center scraper 10 is away from the glass surface and does not operate, while the drive is located at... Figure 7 The upper middle scraper 10 is close to the glass surface to perform scraping work.

[0154] For details on the specific settings of the driving components, please refer to the applicant's prior patent applications numbered 202010670650.2 and 202021375474.1, etc., which will not be repeated here.

[0155] On the other hand, this application also provides a scraping cleaning assembly. The scraping cleaning assembly includes a first scraping cleaning device and a second scraping cleaning device that are magnetically attracted to each other. The first scraping cleaning device can be any of the scraping cleaning devices provided in the foregoing embodiments.

[0156] Since the scraping cleaning component uses the scraping cleaning device provided in the aforementioned embodiments, the scraping cleaning component also has the same technical effects as the aforementioned scraping cleaning device, which will not be described in detail here.

[0157] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
