Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of daily cleaning supplies, and particularly relates to a scraping cleaning device and a scraping cleaning assembly. BACKGROUND

[0002] Dust and impurities remaining on the surface of a glass window greatly affect the appearance of the glass window, and are not conducive to indoor light transmission, so the glass window needs to be cleaned regularly to keep it clean. The emergence of a window cleaner provides great convenience for the cleaning work of the glass window. The window cleaner mainly comprises a wiping body connected to the glass window by magnetic force and a push-pull rod for driving the wiping body to move. When in use, the user drives the wiping body to move on the glass surface by the push-pull rod to wipe, so as to scrape and clean the inner and outer surfaces of the glass window at the same time. It has high cleaning efficiency, and is very convenient and practical to operate.

[0003] In the related art, one side of the wiping body that is attached to the glass is usually provided with a wiping material and a scraping strip. The wiping material is used to brush and clean the glass surface to be cleaned, and can process the slightly larger dirt attached to the glass surface. The scraping strip can scrape off the water stains on the glass surface to be cleaned.

[0004] When in use, the user drives the wiping body to move reciprocally in the up-down direction on the glass surface by the push-pull rod to scrape the glass surface. When the user drives the wiping body to move upward on the glass surface by the push-pull rod, the scraping strip scrapes off the water stains on the glass surface upward, and the water stains gathered flow down from both sides of the scraping strip to form water marks under the action of gravity. The part of the glass surface that has been cleaned is easily contaminated by the water marks. Similarly, when the user drives the wiping body to move downward on the glass surface by the push-pull rod, the water stains gathered flow downward and spread out, and the part of the glass surface that has been cleaned is also easily contaminated. The above reasons make the user need to repeatedly wipe the glass surface, which is time-consuming and laborious, thereby making the cleaning efficiency of the glass cleaner in the prior art not high. SUMMARY

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

[0006] In the first aspect, a scraping cleaning device is provided, comprising: a scraping member and a posture adjustment assembly, wherein the scraping member is connected to the main body of the scraping cleaning device, and can scrape the 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 member so that the scraping member switches between the inclined scraping position and the horizontal scraping position; when the scraping member moves along the first direction, it is in the inclined scraping position, and the first end of the scraping member is located at the front side of the moving direction relative to the second end; when the scraping member moves along the second direction, it is in the horizontal scraping position, and the length direction of the scraping member is approximately perpendicular to the second direction; 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 cleaning 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 in an inclined scraping position or a horizontal scraping position relative to the moving direction of the scraping cleaning device, and when in the inclined scraping position, the first end is always located in the front side of the moving direction relative to the second end, so that 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 in the second direction to wipe the surface to be cleaned, the scraping member switches to the horizontal scraping position. At this time, the water stains move with the scraping member to gather, and will not cause secondary pollution to the cleaned area. The user does not need to wipe repeatedly, thereby improving the cleaning efficiency of the scraping cleaning device and thus improving the user experience. By alternating between the inclined scraping position and the horizontal scraping position, that is, switching from the inclined scraping position to the horizontal scraping position and then from the horizontal scraping position to the inclined scraping position, the angle of the scraping member does not need to change too much during the switching process, and the switching of the scraping member between the two positions can be effectively realized, which can not only achieve comprehensive beneficial technical effects such as scraping cleaning and not causing secondary pollution to the cleaned area, but also save time in switching between the inclined scraping position and the horizontal scraping position, and because the angle of the scraping member does not change much, the switching is also more labor-saving 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 assembly is used to adjust and maintain the scraping member in an inclined scraping position, and when the scraping cleaning 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 horizontal scraping position, and the first direction and the second direction are opposite.

[0012] In a possible design, the posture adjusting assembly includes a fixing member, a swinging member and a limiting member; the fixing member is fixedly connected to the push-pull rod, and the swinging member is connected to the body; the swinging member is hinged to the fixing member, and the swinging member is configured to drive the scraping member to deflect through swinging; and the limiting member is configured to limit the swinging of the swinging member.

[0013] In a possible design, under the action of friction between the scraping cleaning device and the surface to be cleaned, the swinging member is kept on the fixing member through the limiting member, and thus the scraping member is kept in the inclined scraping position or the horizontal scraping position.

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

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

[0016] In a possible design, the power member includes a jacking rod configured to jacking the swinging member to swing.

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

[0018] In a possible design, the limiting member includes an arc-shaped sliding groove and a sliding pin which are used in cooperation; the arc-shaped sliding groove is arranged on one of the fixing member and the swinging member; and the sliding pin is arranged on the other one of the fixing member and the swinging 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.

[0028] In order to achieve a better cleaning effect, a wiping object is usually provided in the middle of the contact surface between the main body of the scraping cleaning device and the surface to be cleaned. Through 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 object 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 cleaning device.

[0029] In a second aspect, a scraping cleaning assembly is provided, comprising a first scraping cleaning device and a second scraping cleaning device attracted to each other by magnetic force, wherein the first scraping cleaning device is a scraping cleaning device provided by any possible design in the first aspect.

DETAILED DESCRIPTION

[0039] 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, not all of them.

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.

[0043] 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.

[0044] First, embodiments of the present application provide a scraping cleaning device, which may be the aforementioned glass eraser and can be used to scrape and clean glass surfaces. Furthermore, the scraping cleaning device can also be used to scrape and clean other surfaces, such as desktops, walls, floors, and blackboards, without limitation in this application.

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

[0046] The scraping member 10 is connected to the body of the scraping cleaning device ( Figure 1 (not shown).

[0047] The posture adjustment assembly 20 is used to adjust the posture of the scraper 10 so that when the scraping and 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, that is, an inclined scraping position. The so-called inclination of the scraper 10 means that the first end 11 of the scraper 10 is always located in front of the moving direction relative to the second end 12. When the scraping and 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 a state where the length direction of the scraper 10 is nearly completely perpendicular to the second direction and a state where the length direction of the scraper 10 is completely perpendicular to the second direction.

[0048] 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.

[0049] The scraping cleaning device provided in an embodiment of the present application includes a scraping member 10, which is connected to the body of the scraping cleaning device. When the scraping cleaning 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 cleaning the surface to be cleaned. When the scraping cleaning device moves back and forth over the surface to be cleaned, the scraping member 10 can also continuously reciprocate and scrape the surface to be cleaned.

[0050] like Figure 1 As shown, the scraping and cleaning 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, that is, when the scraping member 10 moves along the first direction A1, the posture adjustment component 20 adjusts the scraping member 10 so that the scraping member 10 is always in an inclined scraping position relative to the moving direction, that is, 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; when the scraping member 10 moves along the second direction A2, the posture adjustment component 20 adjusts the scraping member 10 so that the scraping member 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 a first direction A1 (in this embodiment, the first direction A1 is an upward direction) 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 scraping position relative to the moving direction, and the first end 11 of the scraping member 10 is located forward of the moving direction relative to the second end 12. At this time, because the scraping member 10 is in the inclined scraping position and the first end 11 is located forward of the second end 12, the scraped water stains will be gathered (gathered, guided) from the first end 11 to the second end 12, thereby preventing secondary contamination of the cleaned area.

[0052] That is, when the scraping cleaning 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 first direction A1. 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 and cleaning 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 cause pollution to the cleaned area on the left.

[0053] After the scraping and cleaning device moves upward to its stop position, it shifts to the right a certain distance and then moves in a 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 posture adjustment assembly 20 further adjusts the posture of the scraping member 10 so that the scraping member 10 is substantially horizontal. That is, the line connecting the first end 11 and the second end 12 of the scraping member 10 is substantially horizontal. In other words, the length of the scraping member 10 is substantially perpendicular to the second direction A2. At this time, since the scraping member 10 is in the horizontal scraping position, the water stains are downward due to the action of gravity, and the scraping member 10 also drives the water stains to move downward, and in addition, the water stains are close to the second end 12 of the scraping member 10. Therefore, under the downward driving action of the scraping member 10 and the downward action of the water stains, when the scraping member 10 reaches the dead point position along the second direction A2, the water stains guided to flow downward 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 worth noting that through the alternating transformation of the inclined scraping position and the horizontal scraping position, that is, switching from the inclined scraping position to the horizontal scraping position, and then switching from the horizontal scraping position to the inclined scraping position, during the switching process, the angle of the scraping member 10 does not need to change too much, and the scraping member 10 can be effectively switched between the two positions, which can not only achieve comprehensive beneficial technical effects such as scraping cleaning and not causing secondary pollution to the cleaned area, but also save time in switching between the inclined scraping position and the horizontal scraping position, and because the angle of the scraping member 10 does not change much, switching is also more labor-saving and efficient.

[0055] The scraping cleaning device provided by the embodiment of the present application includes a scraping member 10 and a posture adjustment assembly 20. The posture adjustment assembly 20 can adjust the posture of the scraping member 10 so that when the scraping member 10 moves in the first direction A1, it is always in an inclined scraping position, and the first end 11 is always located at the front side of the moving direction relative to the second end 12. When the scraping member 10 moves in the second direction A2, it is always in a horizontal scraping position, and the length direction of the scraping member 10 is substantially perpendicular to the second direction A2.

[0056] As a result, when the scraping cleaning device moves back and forth to scrape the surface to be cleaned, water stains are always gathered to the same side in one direction, and are always moved together by the scraping member 10 in the opposite direction, without causing secondary pollution to the cleaned area. The user does not need to wipe repeatedly, thereby improving the cleaning efficiency of the scraping cleaning device and thus enhancing the user experience.

[0057] In an embodiment of the present application, the scraping cleaning device moves back and forth to scrape the surface to be cleaned. The user may manually move the scraping cleaning device to wipe the surface to be cleaned, or the internal motor may drive the scraping cleaning device to move to scrape the surface to be cleaned. The present application does not limit this.

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

[0059] Optionally, the scraping and cleaning device further comprises a walking assembly, which comprises a walking motor, walking wheels and other equipment, thereby enabling the scraping and cleaning device to move automatically without the need for human drive.

[0060] Optionally, the scraping and cleaning device may be a glass-wiping robot, which, in addition to the above-mentioned walking components, also includes sensors and an intelligent control system, etc., and is capable of planning a wiping route, for example.

[0061] In an embodiment of the present application, the scraping cleaning device can be used to scrape and clean glass surfaces, tabletops, walls, floors, blackboards and other surfaces. That is to say, the surface to be cleaned can be any one of glass surfaces, tabletops, walls, floors, blackboards, etc., and this application does not limit this.

[0062] In the embodiment of the present application, the scraping and cleaning 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.

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

[0064] Optionally, the scraping cleaning device may be driven by a user 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.

[0065] 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. 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 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.

[0067] 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.

[0068] In the embodiment of the present application, the scraping member 10 may be a scraper strip.

[0069] Optionally, the scraper strip may be made of plastic or rubber.

[0070] 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.

[0071] Alternatively, the scraping cleaning device can also be a mop. Now, the scraping member 10 can be a mop head.

[0072] In the embodiment of the present application, the scraping member 10 is connected to the main body of the scraping and cleaning 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.

[0073] Optionally, the scraper 10 can be movably connected to the body, in which case the body may not deflect, and the posture adjustment component 20 can drive the scraper 10 to deflect relative to the body, thereby making the scraper 10 in an inclined scraping position or a horizontal scraping position relative to the moving direction.

[0074] 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 scraping position or the horizontal scraping 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.

[0075] 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.

[0076] Furthermore, the scraping cleaning 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 cleaning 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.

[0077] 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 cleaning device and the surface to be cleaned. Through 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 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 cleaning device.

[0078] 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.

[0079] 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.

[0080] Alternatively, the posture of the scraper 10 can be adjusted by the user's manual labor through the posture adjustment assembly 20 .

[0081] 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 .

[0082] Optionally, the posture adjustment assembly 20 can adjust the posture of the scraping member 10 by swinging the scraping member 10 .

[0083] In the embodiment of the present application, when the scraping cleaning device moves back and forth 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, which means that the scraping cleaning device is always in an inclined scraping position relative to the moving direction when moving back and forth.

[0084] For example, when the scraping cleaning 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 scraping position relative to the moving direction. When the scraping cleaning device moves in the direction A2 to scrape the surface to be cleaned, the posture adjustment assembly 20 again adjusts the posture of the scraping member 10 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 moving direction of the scraping cleaning device, and is an angular position. At the inclined scraping position, the scraping member 10 is in an inclined state relative to the moving direction, and the scraping member 10 is neither perpendicular nor parallel to the moving direction; on the contrary, the horizontal scraping position is horizontally arranged relative to the inclined scraping position, and the length direction of the scraping member 10 (that is, the extension direction of the scraping member 10) is approximately perpendicular to the moving direction.

[0086] It is worth mentioning that the inclined scraping position may not be a fixed position (angle). For example, during the movement of the scraping cleaning device, the inclined scraping position may change (i.e., the scraping member 10 may swing). As long as the scraping member 10 is always inclined relative to the moving direction and the first end 11 is always located in front 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.

[0087] like Figure 1As shown in Figure a, when the scraping and cleaning 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 gather water stains to the right.

[0088] Similarly, if Figure 1 As shown in FIG. 2 , when the scraping and cleaning device moves in the second direction A2, the posture adjustment component 20 controls the length direction of the scraping member 10 to be approximately perpendicular to the moving direction. During the movement, the scraping member 10 can also swing to a certain extent, that is, the scraping member 10 swings to a degree where 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 posture adjustment assembly 20 can also adjust and maintain the scraping member 10 in an inclined scraping position. In this case, the posture adjustment assembly 20 controls the angle α1 between the first end 11 and the movement direction to remain constant, 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 posture adjustment assembly 20 can adjust and maintain the scraping member 10 in a horizontal scraping position. In this case, the posture adjustment assembly 20 controls the length direction of the scraping member 10 to remain approximately perpendicular to the second direction A2.

[0090] 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 inclined scraping 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.

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

[0092] The scraping cleaning 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 cleaning device provided by this application using a glass surface as the surface to be cleaned. In other words, the scraping cleaning 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 cleaning device provided in an embodiment of the present application in a working state. Figure 2 (a) is a schematic diagram of the scraping cleaning device moving in the first direction A1. Figure 2 (b) is a schematic diagram of the scraping cleaning 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 scraping position or a horizontal scraping position relative to the moving direction. Optionally, the scraper 10 can be fixed to the body 30 at this time.

[0096] Furthermore, the scraping cleaning device further includes a push-pull rod 40, which is connected to the body 30 via a 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 cleaning device to move, and can also adjust and maintain the scraping member 10 in an inclined scraping position or a horizontal scraping 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 an inclined scraping position, and the scraped water stains are gathered to the right.

[0098] When the scraping and cleaning device is moved to the top dead center, the user can move the body 30 to the right to a certain extent, then use the push-pull rod 40 and the posture adjustment assembly 20 to pull the body 30 downward to scrape and clean the glass surface downward. At this time, the posture adjustment assembly 20 maintains the scraping member 10 in the horizontal scraping position, and the scraped water stains are pulled by the scraping member 10 to converge toward the bottom of the glass window. Until the scraping and cleaning device is moved to the bottom dead center, the user again moves the body 30 to the right to a certain extent, then continues to push the body 30 upward using the push-pull rod 40, thereby achieving 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 the end of the push-pull rod 40 may be provided with a handle 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 2As 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 through the body 30 to be adjusted to the inclined scraping position. When the swinging member 22 is swung to the other extreme position, the swinging member 22 drives the scraping member 10 through the body 30 to be adjusted to the horizontal scraping position.

[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 2 The upper end of the arc-shaped slot 23a), when the swing 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 slot 23a is the second limiting end (i.e. Figure 2 When the swing member 23 is swung and the sliding pin 23b abuts against the second limiting end, the scraping member 10 is adjusted to the horizontal scraping position.

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

[0116] Under the action of the friction between the scraping and cleaning 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 inclined scraping position or the horizontal scraping 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 inclined scraping position, thereby causing the scraped water stains to converge to the right.

[0118] like Figure 2As 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 maintains the scraper 10 in a horizontal scraping position through the body 30. In this horizontal scraping position, the length direction of the scraper 10 is approximately perpendicular to the vertical downward direction, thereby causing the scraped water stains to flow vertically downward and converge.

[0119] That is, when the moving direction of the scraping and 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 and cleaning device and the glass surface, and further maintains the scraping member 10 in the inclined scraping position or the horizontal scraping 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 cleaning device provided in an embodiment of the present application in a working state. Figure 4 (a) is a schematic diagram of the scraping cleaning device moving in the first direction A1. Figure 4 (b) is a schematic diagram of the scraping cleaning device moving 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 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 and cleaning 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 an inclined scraping position and a horizontal scraping 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 24 a; the push rod 24 a 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] In this embodiment, the limiting member 23 is a stopper 23 c, which is used to limit an extreme position of the swinging member 22 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 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 stopper 23c can be provided on the inner wall surface of the bottom plate 21a.

[0131] Figure 5 This is a structural diagram of another example of the scraping cleaning device provided in the embodiment of the present application under working conditions. Figure 5 (a) is a schematic diagram of the scraping cleaning device moving in the first direction A1.Figure 5 (b) is a schematic diagram of the scraping cleaning 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 5 As 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 23 c, which is used to keep the swing member 22 in the inclined scraping position. By adjusting the position of the stopper 23 c and the shape of the swing member 22, the inclination angle of the swing 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 and cleaning 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 the swinging member 22 to abut against the 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 inclined scraping position, thereby causing the scraped water stains to converge to the right.

[0137] like Figure 5As shown in (b), when the body 30 is moved upward on the glass surface to the upper dead point position, the user stops pushing the body 30, and the body 30 is pulled downward by the push-pull rod 40, so as to change the moving direction of the body 30. At this time, when the user pulls the body 30 downward on the glass surface by the push-pull rod 40, the upward frictional force between the scraping cleaning device and the glass surface is generated. That is, at this time, the body 30 is subjected to the upward frictional force, the swing piece 22 swings upward relative to the fixed piece 21, the swing piece 22 drives the body 30, so that the length direction of the scraping piece 10 reaches a position substantially perpendicular to the downward direction, and the scraping piece 10 always remains in the horizontal scraping position under the continuous pulling action of the push-pull rod 40, so as to make the scraped water stains converge to the lower part of the glass window.

[0138] During the swinging of the swing piece 22, the first gear structure 26a rotates relative to the fixed piece 21, and is engaged with the second gear structure 26b, so as to make the swinging of the swing piece 22 more stable and controllable.

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

[0140] With respect to the foregoing Figure 2 , 4 , 5, in the embodiment, the fixed piece 21 and the swing piece 22 are hingedly connected to each other through the swing rod 27.

[0141] Specifically, one end of the swing rod 27 is rotationally connected to the fixed piece 21 through a rotating shaft, and the other end of the swing rod 27 is rotationally connected to the swing piece 22 through a rotating shaft, so as to hingedly connect the fixed piece 21 and the swing piece 22 to each other.

[0142] At this time, the stop block 23c can be fixedly arranged on one side of the swing rod 27, so as to limit the swing piece 22 and further limit the scraping piece 10 in the inclined scraping position.

[0143] Optionally, in the embodiment of the present application, the swing rod 27 is parallelly arranged in two, and in other embodiments, the swing rod 27 can be one, three or more, which is not limited in the present application.

[0144] Figure 7 is a structural schematic diagram of another example of the scraping cleaning device provided by the embodiment of the present application. Figure 8 is Figure 7 a structural schematic diagram of the body 30 in the scraping cleaning device shown in (a).

[0145] like Figure 7 and Figure 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.

[0146] 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 8 The 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 inclined scraping position, so that the scraped water stains are gathered to the right.

[0147] 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 slide groove 33 abuts against the second rotating pin 29. At this time, the main body 30 keeps the scraping member 10 in the horizontal scraping position, so that the scraped water stains are gathered to the lower part of the glass window.

[0148] 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 cleaning device can be changed by rotating the magnetism adjustment knob 31 .

[0149] 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 .

[0150] Furthermore, the two scraping members 10 are fixed and do not switch. However, a preferred solution is that the two scraping members 10 switch. Specifically, a drive assembly can also be provided within the body 30. When the scraping and cleaning device reciprocates to scrape the glass surface, the drive assembly drives the scraping member 10 located at the front side in the direction of movement away from the glass surface and stops working, and drives the scraping member 10 located at the rear side in the direction of movement toward the glass surface to perform scraping.

[0151] 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 cleaning device and the glass surface. Through 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 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 cleaning device.

[0152] For example, when the scraping cleaning device is 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.

[0153] For another example, when the scraping cleaning device moves Figure 7 When 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.

[0154] 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.

[0155] On the other hand, an embodiment of the present application further provides a scraping cleaning assembly, which includes a first scraping cleaning device and a second scraping cleaning device that are attracted to each other by magnetic force. The first scraping cleaning device can be the scraping cleaning device provided by any of the aforementioned embodiments.

[0156] Since the scraping and cleaning assembly adopts the scraping and cleaning device provided by the aforementioned embodiment, the scraping and cleaning assembly also has the corresponding technical effects of the aforementioned scraping and cleaning device, which will not be described in detail here.

[0157] 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.
