Description

Technical Field

[0001] The present application relates to the technical field of daily cleaning products, and in particular to a scraping device and a scraping assembly. Background Art

[0002] Glass windows are exposed to the environment for a long time, and some dust and impurities will remain on the surface. This not only affects the appearance of the glass windows but also hinders the light transmission inside the room. Therefore, the glass needs to be cleaned frequently. The emergence of glass wipers has greatly facilitated the cleaning of glass windows. Glass wipers mainly consist of an interconnected wiper body and a push-pull rod. When in use, the user uses the push-pull rod to move the wiper body across the glass surface to scrape and clean the glass surface, with high cleaning efficiency and practical operation.

[0003] In the related art, a wiper and a scraper are usually provided on the contact surface between the wiper and the glass. The wiper is used to scrub the glass surface to be cleaned and can handle slightly larger dirt attached to the glass surface, while the scraper can scrape off water stains on the glass surface to be cleaned.

[0004] During use, the user uses the push-pull rod to move the wiper back and forth up and down across the glass surface to scrape the glass. As the user uses the push-pull rod to move the wiper upward across the glass surface, the scraper blade scrapes away water stains. Under the influence of gravity, the accumulated water stains flow down from both sides of the scraper blade, forming water marks. These water marks can easily contaminate the cleaned portion of the glass. Similarly, as the user uses the push-pull rod to move the wiper downward across the glass surface, the accumulated water stains flow downward and spread, similarly contaminating the cleaned portion of the glass. These factors require the user to repeatedly wipe the glass surface, which is both time-consuming and labor-intensive, resulting in low cleaning efficiency in conventional glass wipers. Summary of the Invention

[0005] The present application provides a scraping device and a scraping assembly with higher cleaning efficiency.

[0006] In a first aspect, a scraping device is provided, comprising: a scraping member connected to a body of the scraping device; a posture adjustment assembly for adjusting the posture of the scraping member so that when the scraping device moves back and forth to scrape the surface to be cleaned, the scraping member is always in an inclined position relative to the moving direction, and the first end of the scraping member is always located at the front side of the moving direction relative to the second end; wherein the first end is one end of the scraping member along the length direction, and the second end is the other end of the scraping member along the length direction.

[0007] The scraping device provided by the present application includes a scraping member and a posture adjustment component. The posture adjustment component can adjust the posture of the scraping member so that the scraping member is always in an inclined position relative to the moving direction of the scraping device, and the first end is always located in front of the moving direction relative to the second end, so that when the scraping device moves back and forth to scrape the surface to be cleaned, water stains are always gathered to the same side without causing secondary pollution to the cleaned area. The user does not need to wipe repeatedly, thereby improving the cleaning efficiency of the scraping device and thus improving the user experience.

[0008] In one possible design, when the scraping device moves in a first direction to scrape the surface to be cleaned, the posture adjustment assembly is used to adjust and maintain the scraping member in a first inclined position, and when the scraping device moves in a second direction to scrape the surface to be cleaned, the posture adjustment assembly is used to adjust and maintain the scraping member in a second inclined position, and the first direction and the second direction are opposite.

[0010] In a possible design, the posture adjustment component is used to drive the body to deflect, so as to drive the scraping member to deflect, thereby making the scraping member be in the inclined position relative to the moving direction.

[0011] In a possible design, the scraping device further includes a push-pull rod, which is connected to the body through the posture adjustment assembly.

[0012] In one possible design, the posture adjustment assembly includes a fixed part, a swinging part and a limiting part; the fixed part is fixedly connected to the push-pull rod, and the swinging part is connected to the main body; the swinging part is hinged to the fixed part, and the scraping part is driven to deflect by the swinging of the swinging part; the limiting part is used to limit the swinging of the swinging part.

[0013] In a possible design, under the action of the friction between the scraping device and the surface to be cleaned, the swinging member is retained on the fixed member by the limiting member, thereby maintaining the scraping member in the first inclined position or the second inclined position.

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

[0015] In a possible design, the posture adjustment assembly further includes a power member, and when the moving direction of the scraping device switches between the first direction and the second direction, the swing member is deflected under the action of the power member.

[0016] In a possible design, the power member includes a push rod, and the push rod is used to push the swing member to swing.

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

[0018] In one possible design, the limiting member includes an arcuate slide groove and a sliding pin that cooperate with each other; the arcuate slide groove is opened on one of the fixed member and the swing member; and the sliding pin is arranged on the other of the fixed member and the swing member.

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

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

[0021] In a possible design, the fixed member is provided with a first gear structure, and the swing member is provided with a second gear structure, and the first gear structure and the second gear structure are meshed with each other, thereby making the swing of the swing member more stable and controllable.

[0022] In a possible design, the fixed part and the swing part are hinged to each other via a swing rod.

[0023] In a possible design, the fixing member is in a U-shaped structure, and the swinging member is hinged in the cavity of the U-shaped structure, thereby providing a better position limiting effect on the swinging member.

[0024] In one possible design, the posture adjustment assembly includes a U-shaped bracket connected to the push-pull rod, one end of the U-shaped bracket is hinged to the through hole of the side wall of the body through a first rotating pin, and the body (30) can swing relative to the first rotating pin; the other end of the U-shaped bracket is slidably set in the strip groove of the other side wall of the body through a second rotating pin.

[0025] In a possible design, the scraping member is movably connected to the body, and the posture adjustment assembly drives the scraping member to deflect relative to the body, thereby causing the scraping member to be in the inclined position relative to the moving direction.

[0026] In one possible design, the scraping device also includes a driving assembly, the scraping member includes a first scraping member and a second scraping member, and the first scraping member and the second scraping member are respectively arranged on opposite sides of the body; when the scraping device moves back and forth to scrape the surface to be cleaned, the driving assembly drives the scraping member located on the front side of the moving direction away from the surface to be cleaned and stops working, and drives the scraping member located on the rear side of the moving direction close to the surface to be cleaned to perform scraping.

[0027] In order to achieve a better cleaning effect, a wiper is usually provided in the middle of the contact surface between the main body of the scraping device and the surface to be cleaned. Through the above arrangement, it can be ensured that the scraping device scrapes and cleans the surface to be cleaned in the direction of the wiper in front and the scraping member in the back, thereby achieving the technical effect of "wiping first and then scraping", and improving the cleaning efficiency of the scraping device.

[0028] In a second aspect, a scraping assembly is provided, comprising a first scraping device and a second scraping device attracted to each other by magnetic force, wherein the first scraping device is a scraping device provided by any possible design in the first aspect.

DETAILED DESCRIPTION

[0038] The technical solutions of this application will be described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, rather than all the embodiments.

For the same parts in the embodiments of the present application, the figure may only mark one of the parts or components as an example. It should be understood that the figure mark also applies to other identical parts or components.

[0042] In the following, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," etc. may explicitly or implicitly include one or more of the features.

[0043] First, embodiments of the present application provide a scraping device, which may be the aforementioned glass eraser and can be used to scrape and clean glass surfaces. Furthermore, the scraping device can also be used to scrape and clean other surfaces, such as desktops, walls, floors, and blackboards, without limitation in this application.

[0044] Figure 1 This is a schematic diagram of the principle of the scraping device provided in the embodiment of the present application in the working state. Figure 1 (a) is a schematic diagram showing the principle of the scraping device moving in the first direction A1. Figure 1 (b) is a schematic diagram showing the principle of the scraping device moving in the second direction A2. Figure 1 As shown, the scraping device provided in the embodiment of the present application includes: a scraping member 10 and a posture adjustment assembly 20.

[0045] The scraping member 10 is connected to the body of the scraping device ( Figure 1 (not shown).

[0046] The posture adjustment assembly 20 is used to adjust the posture of the scraping member 10 so that when the scraping device moves back and forth to scrape the surface to be cleaned, the scraping member 10 is always in an inclined position relative to the moving direction, and the first end 11 of the scraping member 10 is always located at the front side of the moving direction relative to the second end 12.

[0047] The first end 11 is one end of the scraping member 10 along the length direction, and the second end 12 is the other end of the scraping member 10 along the length direction.

[0048] The scraping device provided in the embodiment of the present application includes a scraping member 10, which is connected to the body of the scraping device. When the scraping device moves over a surface to be cleaned (e.g., a glass surface), the scraping member 10 can scrape the surface to be cleaned, thereby performing a cleaning function. When the scraping device reciprocates over the surface to be cleaned, the scraping member 10 can also continuously reciprocate and scrape the surface to be cleaned.

[0049] like Figure 1As shown, the scraping device provided in the embodiment of the present application also includes a posture adjustment component 20, which is transmission-connected to the scraping member 10 and is used to adjust the posture of the scraping member 10, so that when the scraping device moves back and forth to scrape the surface to be cleaned, the scraping member 10 is always in an inclined position relative to the moving direction, and the first end 11 of the scraping member 10 is always located at the front side of the moving direction relative to the second end 12.

[0050] Specifically, when the scraping device moves in the first direction A1 to scrape the surface to be cleaned, the posture adjustment assembly 20 adjusts the posture of the scraping member 10 so that the scraping member 10 is in an inclined position relative to the direction of movement, and the first end 11 of the scraping member 10 is located forward of the second end 12 in the direction of movement. At this time, because the scraping member 10 is in an inclined position and the first end 11 is located forward of the second end 12, the scraped water stains are gathered (gathered and guided) from the first end 11 to the second end 12, thus preventing secondary contamination of the cleaned area.

[0051] That is, when the scraping device moves in the first direction A1 to scrape the surface to be cleaned, the scraping member 10 can move the water stains to the Figure 1 The right side of the screen is converged, and the user can clean the surface from left to right. Figure 1 The right side of the middle scraping device is an area that has not been cleaned, and the left side is a cleaned area. The water stains are gathered to the right by the scraping member 10 and will not pollute the cleaned area on the left.

[0052] After the scraping device reaches its dead center position, it shifts slightly to the right and then moves in a second direction A2 to scrape the surface to be cleaned. The second direction A2 is opposite to the first direction A1. The posture adjustment assembly 20 adjusts the posture of the scraping member 10 again, maintaining an inclined position relative to the direction of movement, with the first end 11 of the scraping member 10 still located forward of the second end 12 in the direction of movement. At this point, because the scraping member 10 is in an inclined position and the first end 11 is still located forward of the second end 12, the scraped water stains will continue to converge from the first end 11 toward the second end 12, preventing secondary contamination of the cleaned area.

[0053] That is, when the scraping device moves in the direction A2 to scrape the surface to be cleaned, the scraping member 10 can also move the water stains to the direction A2. Figure 1 The right side of the image is converged so that no contamination occurs to the cleaned area on the left.

[0054] The scraping device provided in the embodiment of the present application includes a scraping member 10 and a posture adjustment component 20. The posture adjustment component 20 can adjust the posture of the scraping member 10 so that the scraping member 10 is always in an inclined position relative to the moving direction of the scraping device, and the first end 11 is always located at the front side of the moving direction relative to the second end 12. As a result, when the scraping device moves back and forth to scrape the surface to be cleaned, water stains are always gathered to the same side without causing secondary pollution to the cleaned area. The user does not need to wipe repeatedly, thereby improving the cleaning efficiency of the scraping device and thus improving the user experience.

[0055] In an embodiment of the present application, the scraping device moves back and forth to scrape the surface to be cleaned. The user may manually move the scraping device to wipe the surface to be cleaned, or the internal motor may drive the scraping device to move to scrape the surface to be cleaned. This application does not limit this.

[0056] Optionally, the scraping device may include a push-pull rod, and the user may drive the body of the scraping device to move back and forth via the push-pull rod, thereby scraping and cleaning the surface to be cleaned.

[0057] Optionally, the scraping device further includes a walking assembly, which includes a walking motor, walking wheels and other equipment, thereby enabling the scraping device to move automatically without human drive.

[0058] Optionally, the scraping device may be a glass-wiping robot, which, in addition to the walking components mentioned above, also includes sensors and an intelligent control system, etc., and is capable of planning a wiping route, for example.

[0059] In an embodiment of the present application, the scraping device can be used to scrape and clean glass surfaces, tabletops, walls, floors, blackboards, and other surfaces. That is, the surface to be cleaned can be any one of glass surfaces, tabletops, walls, floors, blackboards, etc., and the present application does not limit this.

[0060] In the embodiment of the present application, the scraping device reciprocates in a first direction A1 and a second direction A2. The first direction A1 and the second direction A2 are any two opposite directions, which are not limited in the present application.

[0061] For example, the first direction A1 may be upward, and the second direction may be downward. Alternatively, the first direction A1 may be downward, and the second direction may be upward.

[0062] Optionally, the user may drive the scraping device to move back and forth in the first direction A1 and the second direction A2. In this case, the first direction A1 may be in front of the user, and the second direction A2 may be behind the user.

[0063] like Figure 1 As shown, in the embodiment of the present 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. At this time, the water stains are gathered to the right side, and the user can clean the surface to be cleaned in order from left to right.

[0064] In other embodiments, the first end 11 and the second end 12 can be swapped. 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, the water stains are gathered to the left side, and the user can clean the surface to be cleaned in order from right to left.

[0065] The present application does not limit the specific structure of the scraping member 10. For example, the scraping member 10 can be any device capable of performing scraping operations, such as a scraper bar, a scraper plate, a cleaning brush, a rag, a mop head, etc.

[0066] In the embodiment of the present application, the scraping member 10 may be a scraper strip.

[0067] Optionally, the scraper strip may be made of plastic or rubber.

[0068] Optionally, the scraping member 10 can be made up of a plurality of scraping strips (or scrapers, cleaning brushes, etc.). For example, the plurality of scraping strips can be connected front to back, or can be parallel to each other to constitute the scraping member 10.

[0069] Alternatively, the scraping device can also be a mop. Now the scraping member 10 can be a mop head.

[0070] In the embodiment of the present application, the scraping member 10 is connected to the main body of the scraping device. The scraping member 10 can be fixedly connected to the main body or movably connected to the main body, and the present application does not limit this.

[0071] Optionally, the scraper 10 may be movably connected to the body, in which case the body may not deflect, and the posture adjustment assembly 20 may drive the scraper 10 to deflect relative to the body, thereby making the scraper 10 in an inclined position relative to the moving direction.

[0072] Optionally, the posture adjustment assembly 20 can also drive the body to deflect, thereby driving the scraper 10 to deflect, thereby making the scraper 10 in the inclined position relative to the moving direction. In this case, the scraper 10 can be fixedly connected to the body or movably connected to the body, which is not limited in this application.

[0073] For example, the scraping member 10 may be movably connected to the main body, such as the scraping member 10 may be able to extend or retract into the main body.

[0074] Furthermore, the scraping device further comprises a driving assembly ( Figure 1 (not shown), 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 device reciprocates to scrape the surface to be cleaned, the drive assembly drives the scraping member 10 located at the front side of the movement direction away from the surface to be cleaned and stops working, and drives the scraping member 10 located at the rear side of the movement direction toward the surface to be cleaned to perform scraping.

[0075] In order to achieve a better cleaning effect, a wiper is usually provided in the middle of the contact surface between the main body of the scraping device and the surface to be cleaned. Through the above arrangement, it can be ensured that the scraping device scrapes and cleans the surface to be cleaned in the direction of the wiper in front and the scraping member 10 in the back, thereby achieving the technical effect of "wiping first and then scraping", and improving the cleaning efficiency of the scraping device.

[0076] This application does not limit the specific form of the drive assembly, as long as it can drive the first scraper and the second scraper to switch between working and non-working states. For the specific configuration of the above-mentioned drive assembly, please refer to the description in the applicant's prior patent applications No. 202010670650.2, No. 202021375474.1, etc., which will not be repeated here.

[0077] In the embodiment of the present application, the posture adjustment component 20 is transmission-connected to the scraper 10, thereby being able to adjust the posture of the scraper 10. The present application does not limit the specific composition of the posture adjustment component 20 and how to adjust the posture of the scraper 10.

[0078] Alternatively, the posture of the scraper 10 can be adjusted by the user's manual labor through the posture adjustment assembly 20 .

[0079] Alternatively, the posture of the scraping member 10 may be adjusted by an electric device (such as a motor) through the posture adjustment assembly 20 .

[0080] Optionally, the posture adjustment assembly 20 can adjust the posture of the scraping member 10 by swinging the scraping member 10 .

[0081] In the embodiment of the present application, when the scraping device reciprocates to scrape the surface to be cleaned, the scraping member 10 is always in an inclined position relative to the moving direction, which means that the scraping device is always in an inclined position relative to the moving direction when reciprocating.

[0082] For example, when the scraping device moves in the first direction A1 to scrape the surface to be cleaned, the posture adjustment assembly 20 adjusts the posture of the scraping member 10 so that the scraping member 10 is in an inclined position relative to the moving direction. When the scraping device moves in the direction A2 to scrape the surface to be cleaned, the posture adjustment assembly 20 adjusts the posture of the scraping member 10 again so that the scraping member 10 is in an inclined position relative to the moving direction.

[0083] Here, the inclined position is a relative position relative to the moving direction of the scraping device and is an angular position. In this inclined position, the scraping member 10 is inclined relative to the moving direction, and the scraping member 10 is neither perpendicular nor parallel to the moving direction.

[0084] In this tilted position, the first end 11 of the scraping member 10 is always located in the front side of the moving direction relative to the second end 12. That is, when the scraping device moves back and forth, the first end 11 of the scraping member 10 always moves in the same direction (for example, Figure 1 The water stains are pushed and gathered to the same side (on the right side).

[0085] It is worth mentioning that the tilted position may not be a fixed position (angle). For example, during the movement of the scraping device, the tilted position may change (i.e., the scraping member 10 may swing). As long as the scraping member 10 is always tilted relative to the moving direction and the first end 11 is always located ahead of the second end 12 in the moving direction, the scraping member 10 can still push and gather the water stains to the same side.

[0086] like Figure 1 As shown in Figure a, when the scraping device moves in a first direction A1, the posture adjustment assembly 20 controls the angle α1 between the first end 11 and the direction of movement. During movement, the scraping member 10 can swing a certain amount, causing the angle α1 to vary. For example, α1 can vary between 5 and 60 degrees. As will be readily understood, even with the swinging of the scraping member 10, since the first end 11 remains in front of the second end 12, the scraping member 10 will continue to push and converge the water stains to the right.

[0087] Similarly, if Figure 1 As shown in Figure 2b, when the scraping device moves in the second direction A2, the posture adjustment assembly 20 controls the angle α2 between the first end 11 and the movement direction. During the movement, the scraping member 10 can also swing a certain amplitude, so that the angle α2 can vary. For example, α2 can vary between 5 and 60 degrees. It is easy to understand that even if the scraping member 10 swings a certain amplitude, it will always push and gather the water stains to the right.

[0088] Optionally, when the scraping device moves in the first direction A1 to scrape the surface to be cleaned, the posture adjustment assembly 20 can further adjust and maintain the scraping member 10 in the first inclined position. At this time, the posture adjustment assembly 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 device moves in the second direction A2 to scrape the surface to be cleaned, the posture adjustment assembly 20 can adjust and maintain the scraping member 10 in the second inclined position. At this time, the posture adjustment assembly 20 controls the angle α2 between the first end 11 and the moving direction to remain unchanged, that is, α2 is a constant value.

[0089] Optionally, to ensure the convergence of water stains and thereby prevent them from flowing to the left side of the scraper 10, when the scraper 10 is in the first inclined position, the angle α1 between the first end 11 and the moving direction is in the range of 5°≤α1≤60°. For example, α1 can be 15°, 30°, 45°, 55°, etc.

[0090] When the scraper 10 is in the second inclined position, the angle α2 between the first end 11 and the moving direction is in the range of 5°≤α2≤60°. For example, α2 can be 15°, 30°, 45°, 55°, etc.

[0091] Optionally, the sizes of α1 and α2 may be the same or different, which is not limited in this application.

[0092] The scraping device provided in the embodiment of the present application will be further described in detail below with reference to the accompanying drawings.

[0093] For ease of description and understanding, the following description will further illustrate the scraping device provided by this application using a glass surface as the surface to be cleaned. In other words, the scraping device described below can be understood as a glass wiper. On this basis, the first direction A1 described below 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 structure of an example of a scraping device provided in an embodiment of the present application in a working state. Figure 2 (a) is a schematic diagram of the scraping device moving in the first direction A1. Figure 2 (b) is a schematic diagram of the scraping device moving in the second direction A2.

[0095] like Figure 2 As shown, in this embodiment, the posture adjustment assembly 20 is used to drive the body 30 to deflect, thereby driving the scraper 10 to deflect, thereby making the scraper 10 in an inclined position relative to the moving direction. Optionally, the scraper 10 can be fixed to the body 30 at this time.

[0096] Furthermore, the scraping device further includes a push-pull rod 40, which is connected to the body 30 via the posture adjustment assembly 20. At this time, the posture adjustment assembly 20 can be used to transmit power from the push-pull rod 40 to enable the scraping device to move, and can also adjust and maintain the scraping member 10 in the tilted position.

[0097] For example, the 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 the first inclined position, and the scraped water stains are gathered to the right.

[0098] When the scraping device is moved to the top dead center, the user can move the body 30 to the right to a certain extent. Then, the user can pull the body 30 downward using the push-pull rod 40 and the posture adjustment assembly 20 to scrape and clean the glass surface downward. At this time, the posture adjustment assembly 20 maintains the scraping member 10 in the second tilted position, and the scraped water stains are still concentrated to the right. Until the scraping device is moved to the bottom dead center, the user can again move the body 30 to the right to a certain extent, and then continue to push the body 30 upward using the push-pull rod 40 to achieve reciprocating movement of the body 30 on the glass surface, thereby achieving continuous cleaning of the glass surface.

[0099] Optionally, to improve practicality, the push-pull rod 40 may be a telescopic rod, and a handle may be provided at the end of the push-pull rod 40 for the user to hold.

[0100] The following will be combined with the Figure 2 The posture adjustment component 20 provided in the embodiment of the present application is further introduced.

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

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

[0103] Optionally, the fixing member 21 and the push-pull rod 40 can be integrally formed by injection molding or other processes.

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

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

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

[0107] In the embodiment of the present application, the fixing member 21 and the swinging member 22 are both plate-shaped structures and are hinged to each other via a rotating shaft 25 .

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

[0109] Figure 3 : is a side view of the fixing member 21 provided in the embodiment of the present application. Figure 3 As shown, the fixing member 21 is generally U-shaped, and the swinging member 22 is hingedly connected to the cavity of the U-shaped structure. In this case, the fixing member 21 includes three parts, namely a bottom plate 21a and two side plates 21b connected to both sides of the bottom plate 21a. The swinging member 22 can be clamped between the two side plates 21b, thereby better limiting the swinging member 22.

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

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

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

[0113] like Figure 2 As shown, in the embodiment of the present application, the limiting member 23 includes an arcuate slot 23a and a sliding pin 23b that cooperate with each other. The arcuate slot 23a is provided on the swinging member 22, and the sliding pin 23b is provided on the side of the fixed member 21 facing the swinging member 22. The rear end of the sliding pin 23b is fixedly connected to the fixed member 21, and the front end is slidably disposed in the arcuate slot 23a.

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

[0115] In the embodiment of the present application, the scraping member 10 can be adjusted and maintained at the first inclined position or the second inclined position by the friction between the scraping device and the glass surface.

[0116] Under the action of the friction force between the scraping device and the glass surface, the swinging member 22 is retained on the fixing member 21 through the limiting member 23, thereby maintaining the scraping member 10 in the first inclined position or the second inclined position.

[0117] Specifically, if Figure 2 As shown in Figure a, when the user pushes the body 30 upward across the glass surface via the push-pull rod 40, friction is generated between the body 30 and the glass surface. More specifically, the body 30 is subjected to a downward frictional force. Under the action of this frictional force, the swinging member 22 swings downward relative to the fixed member 21, causing the first limit end of the arc-shaped sliding groove 23a to abut against the sliding pin 23b. The swinging member 22 is retained on the fixed member 21 by the limiter 23. The swinging member 22, through the body 30, maintains the scraping member 10 in the first tilted position, thereby causing the scraped water stains to converge to the right.

[0118] like Figure 2 As shown in FIG. 2 , when the body 30 moves upward on the glass surface to the top dead center position, the user stops pushing the body 30 and pulls the body 30 downward via the push-pull rod 40, thereby changing the direction of movement of the body 30. At this point, when the user pulls the body 30 downward on the glass surface via the push-pull rod 40, friction is generated between the body 30 and the glass surface. More specifically, the body 30 is subjected to the upward friction. Under the action of this friction, the swinging member 22 swings upward relative to the fixed member 21, causing the second limit end of the arc-shaped slide groove 23a to abut against the sliding pin 23b. The swinging member 22 is retained on the fixed member 21 via the limiter 23. The swinging member 22, through the body 30, maintains the scraper 10 in the second tilted position. In this second tilted position, the first end 11 of the scraper 10 is still located ahead of the second end 12 in the direction of travel, thereby causing the scraped water stains to continue to be concentrated to the right.

[0119] That is, when the moving direction of the scraping device switches between the up and down directions, the swing member 22 can be deflected under the action of the friction between the scraping device and the glass surface, and further maintains the scraping member 10 in the first inclined position or the second inclined position.

[0120] Alternatively, in other embodiments, the positions of the arcuate slot 23a and the sliding pin 23b can be swapped. In this case, the arcuate slot 23a can be provided on the fixed member 21, and the sliding pin 23b can be provided on the side of the swinging member 22. The rear end of the sliding pin 23b is fixedly connected to the swinging member 22, while the front end slides within the arcuate slot 23a. This arrangement can also produce similar technical effects, and this application will not elaborate further here.

[0121] Figure 4 This is a structural diagram of another example of a scraping device provided in an embodiment of the present application in a working state. Figure 4 (a) is a schematic diagram of the scraping device moving in the first direction A1. Figure 4 (b) is a schematic diagram of the scraping device moving in the second direction A2.

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

[0123] The power member 24 can drive the swing member 22 to swing between two extreme positions, thereby enabling the scraper 10 to switch between the first tilted position and the second tilted position. The present application does not limit the specific structure of the power member 24 and how it drives the swing member 22 to swing, as long as it can achieve the above functions.

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

[0125] Furthermore, the power member 24 includes a push-pull handle 24c. The push rod 24a is movably disposed inside the push-pull rod 40. 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 is provided with a slide groove, and the push-pull handle 24c can move back and forth within the slide 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, causing the swing member 22 to swing upward.

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

[0127] Compared with the aforementioned Figure 2 In the embodiment shown, the limiting member 23 is a stopper 23c, and two stoppers 23c may be provided, one on each side of the swinging direction of the swinging member 22. In other words, at least one stopper 23c is provided on each side of the swinging member 22, thereby limiting the swinging of the swinging member 22, allowing the swinging member 22 to swing between two extreme positions.

[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 provided to drive the push rod 24a to push the swing member 22. At this time, a corresponding control button can be provided on the outer wall surface of the push-pull rod 40 to control the operation of the electric device.

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

[0130] like Figure 4 As shown, in this embodiment, the left stopper 23c can be a long wall structure and fixedly connected to the side panels 21b on both sides and the bottom panel 21a at the bottom. The right stopper 23c can be set on the inner wall surface of the bottom panel 21a.

[0131] Figure 5 This is a structural diagram of another example of the scraping device provided in the embodiment of the present application under working conditions. Figure 5 (a) is a schematic diagram of the scraping device moving in the first direction A1. Figure 5 (b) is a schematic diagram of the scraping device moving in the second direction A2.

[0132] Compared with the aforementioned Figure 2 、 4 In the embodiment shown, a first gear structure 26a is provided on the fixed member 21, and a second gear structure 26b is provided on the swing member 22. The first gear structure 26a and the second gear structure 26b are meshed with each other. By providing the meshed 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 5As shown, the first gear structure 26a can be rotatably connected to the inner 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 acts as a supporting wheel and meshes with the second gear structure 26b.

[0134] Optionally, the swing member 22 may be formed into 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 stopper 23c. Two stoppers 23c can be provided, located on both sides of the swinging direction of the swinging member 22. By adjusting the position of the stopper 23c and the shape of the swinging member 22, the swinging range of the swinging member 22 can be limited.

[0136] like Figure 5 As shown in Figure a, when the user pushes the body 30 upward across the glass surface via the push-pull rod 40, a downward frictional force is generated between the scraping device and the glass surface. Specifically, the body 30 is subjected to the downward frictional force. Under the action of this frictional force, the swinging member 22 swings downward relative to the fixed member 21, causing it to abut against the right-hand stopper 23c. The swinging member 22 is retained on the fixed member 21 by the stopper 23c. The swinging member 22, through the body 30, maintains the scraping member 10 in the first tilted position, thereby causing the scraped water stains to converge to the right.

[0137] like Figure 5 As shown in FIG. 2 , when the body 30 moves upward on the glass surface to the top dead center position, the user stops pushing the body 30 and pulls the body 30 downward via the push-pull rod 40, thereby changing the direction of movement of the body 30. At this point, as the user pulls the body 30 downward on the glass surface via the push-pull rod 40, an upward frictional force is generated between the scraping device and the glass surface. In other words, the body 30 is subjected to the upward frictional force. Under the action of this frictional force, the swinging member 22 swings upward relative to the fixed member 21, causing the swinging member 22 to abut against the left stopper 23c. The swinging member 22 is retained on the fixed member 21 by the stopper 23c. The swinging member 22, through the body 30, maintains the scraping member 10 in the second tilted position. In this second tilted position, the first end 11 of the scraping member 10 remains forward of the second end 12 in the direction of travel, thereby causing the scraped water stains to continue to converge to the right.

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

[0139] Figure 6This is a structural diagram of another example of the scraping device provided in the embodiment of the present application under working conditions. Figure 6 (a) is a schematic diagram of the scraping device moving in the first direction A1. Figure 6 (b) is a schematic diagram of the scraping device moving in the second direction A2.

[0140] Compared with the aforementioned Figure 2 、 4 , 5 , in this embodiment, the fixed member 21 and the swing member 22 are hinged to each other through a swing rod 27.

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

[0142] At this time, the stoppers 23 c may be fixedly disposed on both sides of the rocker rod 27 .

[0143] Optionally, the stopper 23c may be fixedly disposed on the fixing member 21 or on the swinging member 22, which is not limited in the present application.

[0144] Optionally, in the embodiment of the present application, there are two rocker rods 27 arranged in parallel. In other embodiments, there may be one, three or more rocker rods 27, which is not limited in the present application.

[0145] Figure 7 This is a structural diagram of another example of the scraping device provided in an embodiment of the present application. Figure 8 yes Figure 7 A schematic structural diagram of the main body 30 in the scraping device is shown.

[0146] like Figure 7 、 8 As shown, in this embodiment, the posture adjustment assembly 20 includes a U-shaped bracket 28 fixedly connected to a push-pull rod 40. One end of the U-shaped bracket 28 is hingedly connected to a through-hole in a side wall of the body 30 via a first pivot pin, allowing the body 30 to swing relative to the first pivot pin. The other end of the U-shaped bracket 28 is slidably disposed within a strip-shaped slot 33 in the other side wall of the body 30 via a second pivot pin 29.

[0147] When the user pushes the body 30 to move upward on the glass surface by pushing the push rod 40, the body 30 is subjected to a downward friction force. Under the action of this friction force, the right end of the body 30 swings downward relative to the left end, so that the limiting end of the strip-shaped slide groove 33 on the front side of the moving direction (i.e. Figure 8The upper end of the middle strip-shaped slide groove 33 abuts against the second rotating pin 29. At this time, the main body 30 keeps the scraping member 10 in the first inclined position, so that the scraped water stains are gathered to the right.

[0148] When the main body 30 moves upward on the glass surface to the top dead center position, the user stops pushing the main body 30 and pulls the main body 30 downward via the push-pull rod 40, thereby changing the moving direction of the main body 30. At this time, when the user pulls the main body 30 downward on the glass surface via the push-pull rod 40, the main body 30 is subjected to an upward friction force. Under the action of this friction force, the right end of the main body 30 swings upward relative to the left end, so that the front limit end of the strip-shaped slide groove 33 in the moving direction (i.e. Figure 8 The end portion of the lower side of the middle strip-shaped slide groove 33 abuts against the second rotating pin 29. At this time, the main body 30 keeps the scraping member 10 in the second inclined position, so that the scraped water stains are gathered to the right.

[0149] like Figure 7 、 8 As shown, a magnetism adjustment knob 31 is further provided on the top cover of the body 30 , and the magnetism of the scraping device can be changed by rotating the magnetism adjustment knob 31 .

[0150] like Figure 8 As shown, in this embodiment, there are two scraping members 10 , which are respectively disposed on two opposite sides of the body 30 .

[0151] Furthermore, a drive assembly can be provided in the main body 30. When the scraping device moves back and forth to scrape the glass surface, the drive assembly drives the scraping member 10 located at the front side of the moving direction away from the glass surface and stops working, and drives the scraping member 10 located at the rear side of the moving direction close to the glass surface to perform scraping.

[0152] In order to achieve a better cleaning effect, a wiper is usually provided in the middle of the contact surface between the main body 30 of the scraping device and the glass surface. Through the above arrangement, it can be ensured that the scraping device scrapes and cleans the surface to be cleaned in the direction of the wiper in front and the scraping member 10 in the back, thereby achieving the technical effect of "wiping first and then scraping", which can improve the cleaning efficiency of the scraping device.

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

[0154] For another example, when the scraping device moves Figure 7When the drive assembly moves downward to scrape the glass surface, the drive assembly drives the Figure 7 The scraper 10 in the middle and lower part is away from the glass surface and does not work, and the drive is located at Figure 7 The scraping member 10 at the upper middle position is close to the glass surface to perform scraping work.

[0155] The specific settings of the drive components can be found in the records in the applicant's prior patent applications No. 202010670650.2, 202021375474.1, etc., and will not be repeated here.

[0156] On the other hand, an embodiment of the present application further provides a scraping assembly, which includes a first scraping device and a second scraping device that are attracted to each other by magnetic force. The first scraping device can be the scraping device provided by any of the aforementioned embodiments.

[0157] Since the scraping assembly adopts the scraping device provided by the aforementioned embodiment, the scraping assembly also has the technical effects corresponding to the aforementioned scraping device, which will not be described in detail here.

[0158] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
