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 influence of the internal and external environment for a long time, and some dust and impurities will remain on the surface, which not only affects the appearance of the glass windows but also hinders the light transmission in the room. Therefore, the glass needs to be cleaned frequently. The emergence of magnetic glass wipers has greatly facilitated the cleaning of glass windows. It uses two mutually attractive wipers to adhere to the inner and outer surfaces of the glass respectively. When using it, the user pushes the inner wiper to move the outer wiper together, achieving the goal of cleaning the inside and outside of the glass window at the same time, with high cleaning efficiency and safety performance.

[0003] In related art, glass wipers typically have a wiper and a scraper on the contact surface between the glass and the wiper. The wiper is used to scrub the glass surface and remove any larger dirt, while the scraper is used to remove water stains. The wiper is located in the middle of the contact surface, while there is usually only one scraper, located at the edge of the contact surface.

[0004] During use, the user must move the glass wiper with the wiper leading the way and the scraper trailing behind to clean the glass surface. If the glass wiper needs to switch directions during movement, the user must rotate the wiper to continue cleaning the glass surface in the opposite direction. This results in a discontinuous cleaning action and inconvenience for the user. Furthermore, these glass wipers struggle to clean corners of the glass, easily leaving blind spots during use. These factors contribute to the low wiping efficiency of existing glass wipers. Summary of the Invention

[0005] The present application provides a scraping device and a scraping assembly, which have higher wiping efficiency and are conducive to improving the wiping effect.

[0006] In the first aspect, a scraping device is provided, comprising a double scraping member, a friction member and a transmission assembly, wherein the double scraping members are arranged alternately, and the friction member is transmission-connected to the double scraping members via the transmission assembly; when the scraping device moves to scrape the surface to be cleaned, the friction member moves backward under the action of the friction force with the surface to be cleaned, so that the friction member drives the scraping member located at the front side of the travel direction away from the surface to be cleaned and stops working through the transmission assembly, and drives the scraping member located at the rear side of the travel direction close to the surface to be cleaned to perform scraping.

[0007] According to the scraping device provided by the present application, the friction member can rub against the surface to be cleaned to generate friction. When the scraping device moves to the right, the friction member is subjected to the leftward friction force and moves to the left (specifically, moves to the left relative to the main body of the scraping device, such as the housing, base, etc.). The right scraping member can further be driven by the transmission assembly to be retracted and not operated, while the left scraping member is extended to perform scraping. When the scraping device is moved to the edge of the surface to be cleaned, the scraping device can be directly controlled to move to the left without rotating the scraping device. At this time, under the action of the friction force, the friction member drives the two scraping members to switch positions through the transmission assembly, that is, the right scraping member is extended to perform scraping, while the left scraping member is retracted and not operated.

[0008] It is worth mentioning that the movement is relative, and the "backward movement" in "the friction member moves backward under the action of the friction force with the surface to be cleaned" is backward movement relative to the main part of the scraping device, such as the shell, base, etc.

[0011] In one possible design, a connecting through hole is provided on the base, and the transmission assembly includes a connecting member movably arranged in the connecting through hole and a translation member movably arranged in the base; when the scraping device moves to scrape the surface to be cleaned, the friction member drives the translation member to move backward relative to the base in the direction of travel through the connecting member, and the translation member further drives the scraping member located on the front side of the travel direction away from the surface to be cleaned and stops working, and drives the scraping member located on the rear side of the travel direction to approach the surface to be cleaned to perform scraping.

[0012] In one possible design, the connecting member includes a transmission belt and two pulleys, the two pulleys are arranged at intervals and are rotatably connected to the base, the transmission belt ring is arranged on the outer periphery of the two pulleys, one side of the transmission belt is fixedly connected to the friction member, and the other side is transmission-connected to the moving member.

[0013] In a possible design, the transmission belt is engaged with the translation member for transmission.

[0014] In a possible design, the transmission belt is a toothed belt, the pulley is a saw gear, and the toothed belt and the saw gear are meshed with each other.

[0015] In one possible design, the transmission assembly also includes a swinging member hinged in the base, and the double scraping members are fixedly connected to the two ends of the swinging member respectively; the translation member is transmission-connected to the swinging member, and when the scraping device moves to scrape the surface to be cleaned, the translation member drives the end of the swinging member located on the front side of the travel direction away from the surface to be cleaned, and drives the end located on the rear side of the travel direction close to the surface to be cleaned.

[0016] In a possible design, protrusions are respectively provided at both ends of the swinging member relative to the middle part, and the lower surface of the translation member is slidably connected to the upper surface of the swinging member to press the protrusions, thereby driving the swinging member to swing.

[0017] In a possible design, the scraping device further includes an orientation component, which is used to orient the displacement of the translation member so that the translation member and the swing member maintain a reliable connection.

[0018] In one possible design, the friction members include two, and the two friction members are respectively arranged on opposite sides of the base, and the two friction members are each connected to a set of transmission components and the double scraping members in a transmission manner; wherein, the two translation members in the two sets of transmission components are fixedly connected by a synchronization member to achieve synchronous movement of the two translation members.

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.

Therefore, a feature specified as "first," "second," etc. may explicitly or implicitly include one or more of the features.

[0036] 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.

[0037] Figure 1 It is a schematic diagram of the overall assembly of the scraping device 100 provided in an embodiment of the present application. Figure 2 3 is a side view of the scraping device 100 provided in an embodiment of the present application. Figure 3 It is a bottom view of the scraping device 100 provided in an embodiment of the present application. Figure 4 This is a schematic diagram of the use status of the scraping device 100 provided in an embodiment of the present application. Figure 5 1 is an exploded view of the scraping device 100 provided in an embodiment of the present application. Figure 6 It is an exploded view of a part of the structure of the scraping device 100 provided in an embodiment of the present application.

[0038] like Figure 1-6 As shown, the scraping device 100 provided in the embodiment of the present application includes: a base 10 , a double scraping member 20 (ie, two scraping members 20 ), a friction member 30 and a transmission assembly 40 .

[0039] The dual scraping members 20 are disposed on opposite sides of the base 10, and the friction member 30 is movably disposed on the outer surface 11 of the base 10. The friction member 30 is in transmission connection with the dual scraping members 20 via a transmission assembly 40. The outer surface 11 of the base 10 is the surface where the base 10 contacts the surface to be cleaned, or in other words, the outer surface 11 is the surface where the base 10 and the surface to be cleaned are in contact with each other.

[0040] When the scraping device 100 moves to scrape the surface to be cleaned, the friction member 30 moves backward relative to the base 10 under the action of the friction force with the surface to be cleaned, so that the friction member 30 drives the scraping member 20 located on the front side of the travel direction away from the surface to be cleaned and stops working through the transmission assembly 40, and drives the scraping member 20 located on the rear side of the travel direction to approach the surface to be cleaned to perform scraping work (for example, wiping water).

[0041] In the embodiment of the present application, the scraping device 100 includes two scraping members 20, which are respectively disposed on two opposite sides of the base 10, for example Figure 1-4 The outer surface 11 is provided on two opposite long sides of the base 10. The friction member 30 is movably mounted on the outer surface 11 and is displaceable relative to the outer surface 11. During use, the friction member 30 rubs against the surface to be cleaned to generate friction. The generated friction is sufficiently large that the friction member 30 moves backward relative to the outer surface 11 (i.e., relative to the base 10), further driving the two scraping members 20 to move via the transmission assembly 40.

[0042] Specifically, the scraping device 100 includes a base 10 and a top cover 60. The top cover 60 further includes a top wall 61 and side walls 62. The side walls 62 are arranged circumferentially around the top wall 61. The top cover 60 can be fixedly attached to the base 10 to form a hollow internal accommodating cavity, in which the transmission assembly 40 is disposed. The friction member 30 is transmission-connected to the dual scraping members 20 via the transmission assembly 40, meaning that the friction member 30 can drive the two scraping members 20 to move via the transmission assembly 40.

[0043] The present application does not limit the specific form of the transmission assembly 40. For example, it may include any number of different components (gears, racks, cams, eccentrics, sliders, belts, connecting rods, etc.) and different connection relationships (abutment, hinged, sliding, gear-rack connection, belt connection, pin-slot connection, etc.) to cooperate with each other to achieve the purpose of transmitting the movement of the friction member 30 to the two scraping members 20, thereby driving the scraping members 20 to move.

[0044] In an embodiment of the present application, the scraping device 100 moves to scrape the surface to be cleaned. The user may manually move the scraping device 100 to wipe the surface to be cleaned, or the internal motor may drive the scraping device 100 to move to scrape the surface to be cleaned. This application does not limit this.

[0045] Optionally, in other embodiments, the scraping device 100 further includes a walking assembly, which includes a walking motor, walking wheels and other equipment, thereby enabling the scraping device 100 to move automatically without human drive.

[0046] Optionally, in other embodiments, the scraping device 100 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 can, for example, plan a wiping route.

[0047] In the embodiment of the present application, the friction member 30 drives the scraping member 20 located at the front side of the travel direction away from the surface to be cleaned and stops working through the transmission assembly 40, and drives the scraping member 20 located at the rear side of the travel direction close to the surface to be cleaned to perform scraping work.

[0048] Among them, driving the scraper 20 away from the surface to be cleaned can be driving the scraper 20 to retract into the scraping device 100, or it can be through other forms, such as folding or pushing down the scraper 20, so that the front end of the scraper 20 can be away from the surface to be cleaned, thereby preventing the scraper 20 from working.

[0049] Accordingly, driving the scraper 20 close to the surface to be cleaned to perform the scraping operation can be achieved by driving the scraper 20 to extend toward the surface to be cleaned, or by other means, such as standing up (straightening) the scraper 20 so that the front end of the scraper 20 is close to the surface to be cleaned (for example, abutting the surface to be cleaned), thereby enabling the scraping operation. This application does not limit the operating mode of the scraper 20, as long as the scraper 20 can be switched between operation and non-operation.

[0050] like Figure 2-4 As shown, in the embodiment of the present application, in order to better wipe the surface to be cleaned, a wiper 90 is fixedly provided on the outer surface 11 of the base 10. For example, the wiper 90 can be a wiping cloth or a sponge. The wiper 90 can be two pieces, which are arranged on opposite sides of the base 10.

[0051] Furthermore, if Figure 2 As shown, the friction member 30 is disposed in the wiper 90 and protrudes from the wiping surface of the wiper 90 , so that the friction member 30 can better rub against the surface to be cleaned.

[0052] like Figure 5 As shown, the outer surface 11 of the base 10 can be formed into a step shape, with the middle protruding on both sides. In this way, after the wiper 90 is fixed on the outer surfaces 11 on both sides, the wiping surface of the wiper 90 can be flush with the outer surface 11 of the middle part of the base 10, thereby making it convenient for users to wipe and use.

[0053] like Figure 2 As shown, in the free state, the front ends of the two scraping members 20 on the left and right sides can be slightly higher than the wiping surface of the wiper 90, thereby reserving a certain amount of space for the scraping members 20 to move. Figure 4 As shown, when the scraping device 100 moves in the direction B (i.e., the right side in the figure) to scrape the surface to be cleaned (not shown in the figure), the friction member 30 is subjected to the friction force and moves backward relative to the base 10 (i.e., moves to the left), and further drives the front scraping member 20 (i.e., the scraping member 20 on the right side) to be retracted away from the cleaning surface without performing the scraping work, and drives the rear scraping member 20 (i.e., the scraping member 20 on the left side) to be extended to approach the surface to be cleaned (at this time, the front end of the rear scraping member 20 can abut against the surface to be cleaned) to perform the scraping work.

[0054] In an embodiment of the present application, the scraping device 100 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.

[0055] like Figure 1-5 As shown, the scraping device 100 further includes a mounting seat 80 , the scraping member 20 is fixed on the mounting seat 80 , and the transmission assembly 40 is in transmission connection with the scraping member 20 via the mounting seat 80 .

[0056] like Figure 1-4 As shown, a gap is formed between the side wall 62 of the top cover 60 and the base 10 , and the gap provides a movable space for the scraping member 20 so that the scraping member 20 can move away from or approach the surface to be cleaned.

[0057] The present application does not limit the specific structure of the scraping member 20. For example, the scraping member 20 can be any device capable of performing scraping operations, such as a scraper bar, a scraper plate, or a cleaning brush.

[0058] In the embodiment of the present application, the scraping member 20 may be a scraper strip.

[0059] Optionally, the scraper strip may be made of plastic or rubber.

[0060] Optionally, the scraper is arc-shaped, with the two opposite ends in the middle protruding away from the base 10 (ie, the two opposite scrapers are in a "()" shape), so as to better collect water.

[0061] Alternatively, the scraping member 20 on each side 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 20.

[0062] The friction member 30 should have a sufficient coefficient of friction to generate sufficient frictional force. Furthermore, the friction member 30 should be resistant to wear, immersion, and corrosion. This application does not limit the specific form of the friction member 30. In the embodiment of this application, the friction member 30 is a friction block. For example, the friction block can be made of plastic, rubber, resin, metal, leather, or other materials. Depending on the surface to be cleaned, the friction block can be adapted to rotate with different materials.

[0063] Preferably, the friction block can be made of leather, which can be animal leather or artificial leather. For example, the animal leather can be cowhide, sheepskin, donkey hide, etc.

[0064] More preferably, the friction block is made of cowhide, which has a suitable friction coefficient, is cheap and easy to obtain, and is wear-resistant, immersion-resistant, and corrosion-resistant, and has a long service life.

[0065] It should be understood that the displacement of the friction member 30 relative to the base 10 is limited and controllable. In the embodiment of the present application, the friction member 30 is quickly moved to its maximum displacement position under the action of friction and maintained at this maximum displacement position, thereby driving the two scraping members 20 to and remaining in the preset position. In this preset position, one scraping member 20 is retracted and inactive, while the other scraping member 20 is extended and capable of scraping. At this time, the scraping device 100 moves as a whole to enable the rear scraping member 20 to perform scraping. During the scraping operation, the friction member 30 remains stationary relative to the base 10, and there is no relative motion between the two. In other words, relative displacement between the friction member 30 and the base 10 only occurs in the following two situations: the first situation is when the scraping device 100 contacts the surface to be cleaned and begins scraping; the second situation is when the scraping device 100 changes direction. In both situations, the relative displacement between the friction member 30 and the base 10 occurs instantaneously, and then the friction member 30 and the base 10 remain relatively stationary in the preset position.

[0066] According to the scraping device 100 provided in the embodiment of the present application, the friction member 30 provided on the base 10 can rub against the surface to be cleaned to generate friction. When the scraping device 100 moves to the right, the friction member 30 moves to the left due to the leftward friction force, and can further drive the right scraping member 20 to be retracted and not work through the transmission assembly 40, and drive the left scraping member 20 to be extended to perform scraping. When the scraping device 100 is moved to the edge of the surface to be cleaned, there is no need to rotate the scraping device 100. The scraping device 100 can be directly controlled to move to the left. At this time, under the action of friction, the friction member 30 drives the two scraping members 20 to switch positions through the transmission assembly 40, that is, the right scraping member 20 is extended to perform scraping, while the left scraping member 20 is retracted and not work. The scraping device 100 provided in the embodiment of the present application has continuity in the entire scraping process, and can wipe the surface to be cleaned back and forth like wiping a blackboard. It is easier to operate, can improve the user's wiping efficiency, and will not form wiping dead corners on the surface to be cleaned, thereby helping to improve the wiping effect.

[0067] In order to more comprehensively describe the function of the scraping device 100, the above description mentions the scraping member 20 on the front side, the scraping member 20 on the rear side, and the scraping member 20 on the left side, the scraping member 20 on the right side, for the purpose of illustrating the two scraping members 20 arranged relatively to each other. In use, whether moving forward and backward for wiping work or moving left and right for wiping work, one of the scraping members 20 performs the scraping work and the other scraping member 20 does not perform the scraping work. This application does not limit this.

[0068] For ease of description and understanding, in the following description, the scraping device 100 provided in the present application will be further explained by taking the glass surface as the surface to be cleaned. That is to say, the scraping device 100 below can be understood as a glass wiper.

[0069] like Figure 5 、 6 As shown, a connecting through hole 12 is opened on the base 10 and passes through the base 10 , and the transmission assembly 40 includes a connecting member 42 movably arranged in the connecting through hole 12 and a translation member 43 movably arranged in the base 10 .

[0070] When the scraping device moves to scrape the surface to be cleaned, the friction member 30 drives the translation member 43 to move backward relative to the base 10 in the direction of travel through the connecting member 42. The translation member 43 further drives the scraping member 20 located on the front side of the travel direction away from the surface to be cleaned and stops working, and drives the scraping member 20 located on the rear side of the travel direction close to the surface to be cleaned to perform scraping.

[0071] In other words, the friction member 30 drives the translation member 43 to move via the connecting member 42. The translation member 43 is restricted to horizontal movement and cannot move vertically. Under the action of the friction member 30, the translation member 43 can move backward relative to the base 10 in the direction of travel. The translation member 43 further transmits this motion to the dual scraping members 20, thereby driving the scraping members 20 to move.

[0072] The present application does not limit the specific form of the connecting member 42, as long as it can transmit the movement of the friction member 30 to the translation member 43 and drive the translation member 43 to move translationally.

[0073] Figure 7 yes Figure 3 Schematic diagram of the cross section from the AA perspective. Figure 7 As shown, in the embodiment of the present application, the connecting member 42 includes a transmission belt 42a and two pulleys 42b. The two pulleys 42b are arranged at intervals and are rotatably connected to the base 10. The transmission belt 42a is arranged on the outer periphery of the two pulleys 42b. One side of the transmission belt 42a is fixedly connected to the friction member 30, and the other side is transmission-connected to the translation member 43.

[0074] Specifically, in this embodiment, transmission can be achieved through a transmission belt 42a. In this case, a slot can be provided in the wall of the connecting through hole 12, and a pulley 42b can be rotatably connected to the slot. The two pulleys 42b are spaced apart, and the transmission belt 42a is wrapped around the outside of the two pulleys 42b. The two pulleys 42b have the same outer diameter, and the plane on which the two rotating shafts lie should be parallel to the outer surface 11. In turn, the friction member 30 provided on the transmission belt 42a is also parallel to the outer surface 11.

[0075] When the friction member 30 moves backward under the action of the friction force, it can drive the transmission belt 42a to rotate, and then drive the translation member 43 to move through the transmission belt 42a.

[0076] The present application does not limit the transmission mode of the transmission belt 42a and the translation member 43. In the embodiment of the present application, the transmission belt 42a and the translation member 43 are meshed for transmission.

[0077] At this time, a first serrated structure 42c is provided on the side of the transmission belt 42a facing the movable member 43, and a second serrated structure 43a is provided on the side of the movable member 43 facing the transmission belt 42a. The transmission belt 42a and the movable member 43 are engaged and transmitted through the first serrated structure 42c and the second serrated structure 43a.

[0078] Furthermore, in order to better connect and fix the transmission belt 42a, as shown in FIG. Figure 7As shown, in the embodiment of the present application, the transmission belt 42a is a toothed belt, the pulley 42b is a saw gear, and the toothed belt and the saw gear are meshed with each other.

[0079] like Figure 5 、 6 As shown, the transmission assembly 40 also includes a swinging member 41 hinged in the base 10, and the double scraping members 20 are fixedly connected to the two ends of the swinging member 41 respectively; the translation member 43 is transmission-connected to the swinging member 41. When the scraping device 100 moves to scrape the surface to be cleaned, the translation member 43 drives the end of the swinging member 41 located on the front side of the travel direction away from the surface to be cleaned, and drives the end located on the rear side of the travel direction close to the surface to be cleaned.

[0080] Specifically, the swing member 41 is hinged to the inner surface of the base 10 and can swing relative to the base 10. The two ends of the swing member 41 are respectively fixedly connected to the double scraping member 20, so that the swing member 41 can drive the double scraping member 20 to swing.

[0081] In this way, when the scraping device 100 moves to the right, the friction member 30 moves to the left due to the leftward friction force. At this time, the friction member 30 can drive the swing member 41 to swing through the connecting member 42 and the translation member 43 in sequence, so that the right end of the swing member 41 is lifted, and then the scraping member 20 at the right end is retracted and away from the glass surface and stops working. At the same time, the left end of the swing member 41 is dropped, driving the scraping member 20 at the left end to be extended and close to the glass surface (for example, attached to the glass surface) to perform scraping.

[0082] When it moves to the edge of the glass, the scraping device 100 can be controlled to move to the left. At this time, because the direction of the friction force on the friction member 30 changes, the swing member 41 can be driven to swing in the opposite direction, and the position of the double scraping member 20 is switched.

[0083] like Figure 4-6 As shown, the swing member 41 can be fixedly connected to the scraping member 20 via the mounting seat 80 .

[0084] Furthermore, the swing member 41 and the mounting seat 80 can be manufactured through an integral molding process, thereby facilitating improvement of the mechanical strength of the connection between the two.

[0085] Optionally, the one-piece molding process may be an injection molding process.

[0086] The swing member 41 is hinged to the inner surface of the base 10. This application does not limit how the swing member 41 is hinged to the inner surface of the base 10. For example, a rotating shaft can be provided on the side wall of the swing member 41, and the rotating shaft can be rotatably connected to the rotating shaft mounting seat on the inner surface of the base 10, thereby realizing the hinge connection between the two.

[0087] In other embodiments, a hinge hole is formed in the middle of the swing member 41, into which a hinge shaft is fixedly mounted. A hinge seat is provided on the inner surface of the base, which extends into the hinge hole and is rotatably connected to the hinge shaft. In this case, the hinge seat has a mounting hole into which the hinge shaft can be inserted and rotated relative to the mounting hole. This arrangement brings the bottom surface of the swing member closer to the inner surface of the base, thereby making the swing of the swing member more controllable.

[0088] This application does not limit how the translation member 43 and the swing member 41 are connected in transmission. Figure 6 As shown, protrusions 41a are respectively provided at both ends of the swing member 41 relative to the middle part, and the lower surface of the translation member 43 is slidably connected to the upper surface of the swing member 41 to press the protrusions 41a, thereby driving the swing member 41 to swing.

[0089] That is, the translation member 43 is disposed above the swing member 41, and the two maintain a sliding connection. Since the swing member 41 is hinged to the inner surface of the base 10, a protrusion 41a is provided at each end of the swing member 41, and the protrusion 41a is higher than the middle portion of the swing member 41. Since the translation member 43 is restricted to horizontal forward and backward movement, when the translation member 43 moves toward one end of the swing member 41, it can press the protrusion 41a at that end, thereby driving that end of the swing member 41 downward and the other end upward.

[0090] Specifically, when the scraping device 100 moves rightward, the friction member 30 moves leftward due to the leftward friction force. At this time, the connecting member 42 drives the translation member 43 to move leftward. The translation member 43 presses the protrusion 41a at the left end of the swinging member 41, causing the left end of the swinging member 41 to be pressed down and the right end to be tilted up. This further drives the left end of the scraping member 20 down toward the glass surface to start wiping, and drives the right end of the scraping member 20 to be tilted away from the glass surface and stop working.

[0091] Furthermore, if Figure 6 As shown, the translation member 43 is divided into a left part and a right part. The left part is connected to the friction member 30 through the connecting member 42 (that is, the second serrated structure 43a is arranged on the left part), and the right part maintains a sliding connection with the swinging member 41. The shape of the right part can be adapted to the shape of the swinging member 41 to facilitate sliding relative to the swinging member 41 and to facilitate pressing the swinging member 41.

[0092] Figure 8 Schematic diagram of the connection of the directional assembly 50 provided in the embodiment of the present application. Figure 5 、 6As shown in Figures 8 and 9, the scraping device 100 further includes an orientation assembly 50 for orienting the displacement of the translation member 43 so that the translation member 43 maintains a secure connection with the swing member 41. The orientation assembly 50 can control the displacement of the translation member 43 so that the translation member 43 does not separate from the swing member 41, thereby improving the performance of the scraping device 100.

[0093] Here, maintaining a reliable connection between the translation member 43 and the swing member 41 through the orientation component 50 means controlling the movement trajectory of the translation member 43 through the orientation component 50, so that the translation member 43 and the swing member 41 will not be separated, always remain connected, and undergo relative displacement according to a predetermined trajectory.

[0094] like Figure 8 As shown, in the embodiment of the present application, the orientation assembly 50 includes a roller 51 and a guide rail 52 that cooperate with each other; the roller 51 is rotatably disposed on the upper surface of the translation member 43 via a rotating shaft, and the guide rail 52 is fixedly disposed on the inner surface of the top wall 61. The roller 51 can roll along the guide rail 52.

[0095] In other embodiments, the positions of the roller 51 and the guide rail 52 can be reversed. The roller 51 can be rotatably arranged on the inner surface of the top wall 61, and the guide rail 52 can be fixedly arranged on the upper surface of the translation member 43, which can also achieve similar effects as described above.

[0096] This application does not limit the specific configuration of the orientation assembly 50, as long as it can achieve the aforementioned displacement orientation. For example, in other embodiments, the orientation assembly may include a sliding pin and a sliding groove that adapt to each other. In this case, a mounting wall can be provided at the edge of the base 10, and the sliding pin can be provided on either the inner surface of the mounting wall or the side surface of the translation member, while the sliding groove can be provided on the other of the inner surface of the mounting wall and the side surface of the translation member.

[0097] like Figure 3 、 5 As shown in Figures 6 and 7, in the embodiment of the present application, two friction members 30 are provided on opposite sides of the outer surface 11. Each friction member 30 is in transmission connection with the dual scraper 20 via a transmission assembly 40. The two translation members 43 in the two transmission assemblies 40 are fixedly connected via a synchronizer 70 to achieve synchronized motion of the two translation members 43. This arrangement not only enables synchronized motion of the two translation members 43 but also facilitates better control of the displacement of the translation members 43 and ensures a reliable connection between the translation member 43 and the swinging member 41.

[0098] like Figure 6As shown, in the embodiment of the present application, the synchronizer 70 is frame-shaped, and the two sides are fixedly connected to the translation member 43. In other embodiments, the synchronizer 70 may also be in other shapes, such as "X" shape, etc., which is not limited in the present application.

[0099] The two translation members 43 and the synchronization member 70 are made by an integral molding process. Through the above arrangement, the stability of the mechanical connection can be improved. For example, the integral molding process can be injection molding.

[0100] like Figure 6 As shown, in the embodiment of the present application, two swing members 41 are also arranged on opposite sides of the base 10, and each swing member 41 is connected to the double scraping member 20. Through the above arrangement, the scraping member 20 can be better lifted and lowered.

[0101] Optionally, the two swing members 41 and the two mounting seats 80 can be made by an integral molding process to improve the stability of the mechanical connection. For example, the integral molding process can be injection molding.

[0102] On the other hand, an embodiment of the present application further provides a scraping assembly 1000 . Figure 9 Schematic diagram of the structure of the scraping assembly 1000 provided in the embodiment of the present application. Figure 9 As shown, the scraping assembly 1000 includes: a first scraping device 200 and a second scraping device 300 that can be attracted to each other, and at least one of the first scraping device 200 and the second scraping device 300 is the scraping device 100 provided in any of the aforementioned embodiments.

[0103] Furthermore, the scraping assembly 1000 further includes an anti-suction baffle 400 , and the first scraping device 200 is connected and fixed to the second scraping device 300 via the anti-suction baffle 400 .

[0104] Optionally, the first scraping device 200 is provided with a winding device, and the second scraping device 300 is provided with a magnetic adjustment device.

[0105] Optionally, the first scraping device 200 and the second scraping device 300 are provided with magnets with different polarities.

[0106] Optionally, one of the first scraping device 200 and the second scraping device 300 is provided with a magnet, and the other is provided with a magnetic material such as an iron block or a steel block.

[0107] Optionally, the first scraping device 200 and the second scraping device 300 are attracted to each other by electromagnets.

[0108] Optionally, at least one of the first scraping device 200 and the second scraping device 300 is further provided with a travel motor, which is used to drive the scraping device to move.

[0109] Since the scraping assembly 1000 adopts the scraping device 100 provided in the above embodiment, the scraping assembly 1000 also has the technical effects corresponding to the above scraping device 100, which will not be described in detail here.

[0110] 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.
