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

In a first aspect, embodiments of the present application first provide a scraping device, which may be the glass eraser, and can be used to scrape and clean the surface of glass. In addition, the scraping device can also be used for scraping and cleaning other surfaces such as a table top, a wall surface, a ground, a blackboard and the like, and the application does not limit the scraping device.

As shown in fig. 1 to 6, a scraping apparatus provided in an embodiment of the present application includes: a base, a double scraper 20 (i.e. two scrapers 20) and a transmission assembly.

Wherein the double scraping elements 20 are arranged at two opposite positions on the base, and the rotating element 30 is used for contacting with the surface to be cleaned, and the rotating element 30 is in transmission connection with the double scraping elements 20 through a transmission component.

When the scraping device moves to scrape the surface to be cleaned, the rotating member 30 moves backward with respect to the abutting surface 11 (i.e., with respect to the base) under the action of the friction force with the surface to be cleaned, so that the rotating member 30 does not operate by driving the scraping member 20 located at the front side in the traveling direction away from the surface to be cleaned through the transmission assembly, and drives the scraping member 20 located at the rear side in the traveling direction close to the surface to be cleaned to perform the scraping work.

In one embodiment, as shown in fig. 1-4, 6, 8, the base may include a bottom plate 13, a top cover 14; the top cover 14 further comprises a top wall 14a and a side wall 14b, the side wall 14b is disposed around the circumference of the top wall 14a, and the top cover 114 can be fixedly covered on the bottom plate 13, so as to form a hollow accommodating cavity. In other embodiments, the base may be a plate-like structure, a frame structure, or the like. The present application does not specifically limit the specific structural form of the base.

In this application, the bottom plate 13 can be provided with the connecting through hole 12, the rotating member 30 is rotatably disposed in the connecting through hole 12, and the rotating member 30 penetrates through the connecting through hole 12. The end of the rotatable member 30 outside the base may be used to contact the surface to be cleaned. The rotation member 30 is rotatably disposed in the connecting through hole 12, and it is possible that the rotation member 30 is rotatably connected in the connecting through hole 12, or that the rotation member 30 is rotatably connected to other components of the scraping apparatus, so that the rotation member can rotate relative to the connecting through hole 12.

In this application, the surface of the bottom plate 13 abutting the surface to be cleaned may be referred to as a fitting surface 11, the fitting surface 11 is a bottom surface of the base, and the double scrapers 20 may be respectively disposed on two opposite sides of the fitting surface 11.

In the embodiment of the application, the scraping device comprises two scraping elements 20, which are arranged at two opposite positions on the base, for example at two opposite long sides of the bottom surface of the base in fig. 1-3. In use, the rotating member 30 can rub against the surface to be cleaned to generate a friction force, and the generated friction force is large enough so that under the action of the friction force, the rotating member 30 can rotate backward relative to the base, and further drive the two scraping members 20 to move through the transmission assembly.

The transmission assembly can be arranged in the accommodating cavity. The rotary member 30 is drivingly connected to the double scraping members 20 by means of a transmission assembly, i.e. the rotary member 30 is able to drive the two scraping members 20 in motion by means of the transmission assembly.

The scraping member 20 may be a scraping member such as a scraping strip or a scraping blade, or may be other members that can be used to scrape the surface of the object to be cleaned, and is not particularly limited herein.

The present application is not limited to the specific form of the transmission assembly. For example, the transmission assembly may be a block structure, a plate structure, a shell structure, or may include any of a plurality of different structures (gears, racks, cams, eccentric wheels, sliders, belts, connecting rods, etc.), and components that are engaged with each other in different connection relationships (abutting, hinged, sliding, gear-rack connection, belt connection, pin-and-slot connection, etc.), so as to transmit the motion of the rotating member 30 to the two scraping members 20 to drive the scraping members 20 to move.

In this application embodiment, the scraping device moves to scrape the surface to be cleaned, and the scraping device may be manually moved by a user to scrape the surface to be cleaned, or the scraping device may be driven by an internal motor to move to scrape the surface to be cleaned.

Optionally, in other embodiments, the scraping device further includes a walking assembly, and the walking assembly includes a walking motor, a walking wheel and other devices, so that the scraping device can automatically walk without manual driving.

Alternatively, in other embodiments, the scraping device may be a glass cleaning robot, which, in addition to the above-mentioned walking assembly, also comprises sensors, intelligent control systems, etc., for example, which can plan the cleaning route.

In the present embodiment, the rotating member 30 is not operated to drive the scraping member 20 located at the front side in the traveling direction away from the surface to be cleaned through the transmission assembly, and drives the scraping member 20 located at the rear side in the traveling direction close to the surface to be cleaned for the wiping operation.

The driving of the scraping element 20 away from the surface to be cleaned may be to drive the scraping element 20 to retract into the scraping device, or may be in other forms, such as folding, pushing over the scraping element 20, etc., so that the front end of the scraping element 20 can be away from the surface to be cleaned, and thus the scraping element 20 can be made to not work.

Accordingly, the wiping operation can be performed by driving the wiper member 20 close to the surface to be cleaned, by driving the wiper member 20 to protrude toward the surface to be cleaned, or by other forms, such as raising (straightening) the wiper member 20, etc., so that the leading end of the wiper member 20 is close to the surface to be cleaned. The present application does not limit the operation of the driving scraper 20, as long as the scraper 20 can be switched between operating and non-operating.

In the present embodiment, the double scraping elements (20) can be arranged parallel to each other for better scraping of the surface to be cleaned.

As shown in fig. 1-2 and 4, in the embodiment of the present application, a wiping member 90 may be fixedly disposed on the abutting surface 11 for better wiping the surface to be cleaned. For example, the wiper 90 may be a wipe or sponge or the like. The wipe 90 may be two pieces, disposed in opposing positions on the base.

Further, as shown in fig. 2, the rotating member 30 is disposed inside the wiping member 90, and the rotating member 30 protrudes from the wiping surface of the wiping member 90, so that the rotating member 30 can better perform a relative friction with the surface to be cleaned.

As shown in fig. 6, the abutting surface 11 may be formed in a step shape, and the middle of the step shape protrudes from two opposite sides, so that after the wiping member 90 is fixed on the abutting surfaces 11 at two sides, the wiping surface of the wiping member 90 may be flush with the abutting surface 11 at the middle portion, thereby facilitating wiping for a user.

As shown in fig. 2, in the free state, the front end portions of the two scraping members 20 on the left and right sides may be slightly higher than the wiping surface of the wiping member 90, thereby reserving a certain movement space for the scraping members 20. As shown in fig. 4, when the wiper device moves in the direction B (i.e., right side in the figure) to wipe the surface to be cleaned (not shown in the figure), the rotating member 30 is rotated backward relative to the base by friction, and further the driving assembly inside the wiper device drives the front wiper member 20 (i.e., right wiper member 20) to be retracted away from the surface to be cleaned, without wiping, and drives the rear wiper member 20 (i.e., left wiper member 20) to be extended close to the surface to be cleaned (at this time, the front end of the rear wiper member 20 can abut against the surface to be cleaned), so as to perform wiping. The rotation member 30 rotates backward relative to the base, that is, the rotation member 30 rotates backward relative to any part of the base, for example, the rotation member 30 rotates backward relative to the base plate 13, or the rotation member 30 rotates backward relative to the top cover 14.

In this application embodiment, the scraping device can be used to scrape and clean surfaces such as glass surfaces, table tops, wall surfaces, floors and blackboards, that is, the surface to be cleaned can be any one of glass surfaces, table tops, wall surfaces, floors and blackboards, and this application does not limit this.

As shown in fig. 1-2 and 4, a gap is formed between the side wall 14b of the top cover 14 and the bottom plate 13, and the gap provides a movable space for the scraping member 20 so that the scraping member 20 can move away from or close to the surface to be cleaned.

Alternatively, scraper member 20 may be constructed of a plastic or rubber material.

Optionally, scraper members 20 are arcuate with the middle opposite ends projecting away from the base (i.e., in an "over" shape) to better collect water.

The rotor 30 should have a sufficient coefficient of friction to generate sufficient friction and the rotor 30 should also be wear resistant, soak resistant, and corrosion resistant. The present application is not limited to the specific form of the rotating member 30. In the present application, the rotating member 30 may be a block or a cylinder, for example, the rotating member 30 may be a block made of plastic or resin, and the friction block 30 may also be a block with a rubber layer or a leather layer attached to the surface thereof.

It will be understood that the displacement of the rotating member 30 with respect to the base is limited and controllable, and in the embodiment of the present application, the rotating member 30 is moved quickly by friction to the maximum displacement and is maintained at this maximum displacement, while the two scraping members 20 are also brought to the preset position and are maintained at this preset position. In this preset position, one of the wipers 20 is retracted out of service, while the other wiper 20 is extended to enable wiping operation.

According to the scraping device provided by the embodiment of the application, the rotating part 30 can generate mutual friction to generate friction force after contacting with the surface to be cleaned, when the scraping device moves rightwards, the rotating part 30 rotates leftwards due to the friction force applied to the rotating part, the scraping part 20 on the right side can be further driven by the transmission assembly to be retracted and not work, and the scraping part 20 on the left side is driven to be stretched out to conduct scraping work. When the direction of the scraping device needs to be switched in the using process, the scraping device can be directly controlled to move leftwards, at the moment, under the action of friction force, the rotating piece 30 drives the positions of the double scraping pieces 20 to be switched through the transmission assembly, namely, the scraping piece 20 on the right side is stretched out to conduct scraping work, and the scraping piece 20 on the left side is folded and does not work. The whole scraping process of the scraping device provided by the embodiment of the application has continuity, the surface to be cleaned can be cleaned in a reciprocating mode like a blackboard, the operation is simpler and more convenient, the cleaning efficiency of a user can be improved, and dead angles cannot be formed on the surface to be cleaned, so that the cleaning effect is improved.

For ease of presentation and understanding, the scraping device provided herein will be further described in the following description with the glass surface as the surface to be cleaned, i.e., the scraping device may be understood as a glass wiper hereinafter.

In one embodiment, as shown in fig. 6 and 8, the transmission assembly may include: and the moving piece 40 is connected with the base in a sliding way. The moving member 40 is slidably connected to the base, and may be slidably connected to the bottom plate 13 of the base.

When the scraping device moves to scrape the surface to be cleaned, the rotating member 30 rotates backward relative to the base under the friction force with the surface to be cleaned to drive the moving member 40 to move backward relative to the base in the traveling direction, the moving member 40 further drives the scraping member 20 located at the front side in the traveling direction to be away from the surface to be cleaned and not to work, and drives the scraping member 20 located at the rear side in the traveling direction to be close to the surface to be cleaned to perform the scraping work. The moving member 40 moves backward relative to the base in the traveling direction, and the moving member 40 may move backward relative to the bottom plate 13 or the top cover 14 in the traveling direction.

Specifically, the moving member 40 can be slidably disposed in the cavity formed by the bottom plate 13 and the top cover 14.

In one embodiment, as shown in fig. 5-7, the rotating member 30 may be rotatably coupled to the base, for example, the rotating member 30 may be rotatably coupled to the bottom plate 13 of the base, and when the base is a plate-like structure, the rotating member 30 may be rotatably coupled to the plate-like structure. The rotating member 30 can be in driving connection with the moving member 40 through a rack and pinion. The rotary member 30 can drive the moving member 40 by means of the rack and pinion to move backward in the direction of travel relative to the base when the scraping means is moved to scrape the surface to be cleaned.

In one implementation, the rotating member 30 may be rotatably connected to the base, a portion of the rotating member 30 adjacent to the moving member 40 may be the gear structure 31, a portion of the moving member 40 adjacent to the rotating member 30 may be the rack structure 44, and the gear structure 31 and the rack structure 44 are engaged with each other. That is, the lower half portion of the rotating member 30 may be the gear structure 31, and the portion of the moving member 40 located below the rotating member 30 may be the rack structure 44, in which case, the rotating member 30 may be regarded as a partial gear, and the moving member 40 may be regarded as a partial rack. When the rotating member 30 rotates to drive the double scraping members 20 to switch, the rotating member 30 can realize the switching of the double scraping members 20 within a certain rotating range, therefore, the part of the rotating member 30 close to the moving member 40 is the gear structure 31, and the part of the moving member 40 close to the rotating member 30 is the rack structure 44, which can realize the switching of the working bodies of the double scraping members 20 and can also make the structure of the scraping device simpler.

Specifically, the first swinging member 80 and the rotating member 30 may be an integrally formed structure.

Specifically, as shown in fig. 8, a transmission groove 45 may be provided on an outer surface of the moving member 40 facing the first swinging member 80, and the first swinging member 80 extends into the transmission groove 45. The first swinging member 80 extends into the transmission groove 45, so that the first swinging member 80 can drive the moving member 40 to move in the direction opposite to the traveling direction.

Specifically, as shown in fig. 8, the rotation member 30 may be a cam.

In one embodiment, as shown in fig. 10-12, the rotating member 30 may also be rotatably coupled to the moving member 40. When the scraping device moves to scrape the surface to be cleaned, the rotating member 30 rotates backward relative to the base under the friction force with the surface to be cleaned, so as to drive the moving member 40 to move backward, the moving member 40 further drives the scraping member 20 located at the front side in the traveling direction to be away from the surface to be cleaned and not to work, and drives the scraping member 20 located at the rear side in the traveling direction to be close to the surface to be cleaned to perform scraping work. The rotating member 30 may be rotatably connected to a side surface of the moving member 40, or may be rotatably connected to the inside of the moving member 40. Specifically, as shown in fig. 10 to 11, a face of the moving member 40 facing the rotating member 30 may be provided with a coupling groove 1g, the rotating member 30 extends into the coupling groove 1g, and the rotating member 30 is rotatably coupled in the coupling groove 1 g. Further, after the rotation member 30 is inserted into the connection groove 1g, the rotation pin 1b may be used to penetrate the moving member 40 and to be inserted into the rotation member 30. The scraping device in the embodiment is simple in structure and stable in transmission.

As shown in fig. 5, 8, 10-11, the above-mentioned transmission assembly may further include: a second oscillating member 41 hinged to the inner side of the base, the double scraping members 20 being fixedly connected to the positions of the two sides of the hinge axis of the second oscillating member 41, respectively;

the moving member 40 is in transmission connection with the second swinging member 41, and when the scraping device moves to scrape the surface to be cleaned, the moving member 40 drives one end of the second swinging member 41 located at the front side of the traveling direction to be away from the surface to be cleaned and drives one end located at the rear side of the traveling direction to be close to the surface to be cleaned.

Specifically, the second swinging member 41 is hinged in the base and can swing relative to the base, and two ends of the second swinging member 41 are respectively and fixedly connected with the double scraping members 20, so that the second swinging member 41 can drive the double scraping members 20 to swing.

Thus, when the scraping device moves rightwards, the rotating member 30 rotates leftwards relative to the base due to the friction force applied leftwards, at this time, the rotating member 30 can drive the second swinging member 41 to swing through the moving member 40, so that the right end of the second swinging member 41 is lifted, the scraping member 20 at the right end is driven to be retracted and away from the surface of the glass, and the scraping member 20 at the left end is driven to be stretched out and close to the surface of the glass (for example, attached to the surface of the glass) to conduct scraping work, and meanwhile, the left end of the second swinging member 41 is driven to fall down.

When the scraping direction needs to be switched, the scraping device can be controlled to move leftwards, at this time, because the direction of the friction force applied to the rotating member 30 changes, the second swinging member 41 can be driven to swing in the opposite direction, and the positions of the double scraping members 20 are switched.

As shown in fig. 5-12, the second oscillating member 41 can be fixedly connected to the wiper member 20 via the wiper member mount 1 d.

Further, the second swinging member 41 and the wiper mount 80 may be formed by an integral molding process, thereby facilitating an improvement in the mechanical strength of the connection therebetween.

Alternatively, the integral molding process may be an injection molding process.

The second swinging member 41 is hinged in the base, and the application does not limit how the second swinging member 41 is hinged in the base. For example, a rotating shaft may be provided on a side wall of the second swinging member 41, and the rotating shaft may be rotatably connected to a rotating shaft mounting seat in the base, so as to realize the hinge joint of the two.

In addition, in other embodiments, a hinge hole may be formed in the middle of the second swinging member 41, a hinge shaft 1e is fixedly disposed in the hinge hole, and a hinge seat is disposed on the inner side of the base, extends into the hinge hole and is rotatably connected with the hinge shaft 1 e. At this time, the hinge base is formed with a mounting hole into which the hinge shaft 1e can be fitted and can rotate with respect to the mounting hole. With the above arrangement, the bottom surface of the second swinging member 41 is brought closer to the inner side of the base, thereby making the swinging of the second swinging member more controllable.

In one realisation, the double scraping elements 20 can be distributed symmetrically with respect to the hinging axis of the second oscillating element 41.

Specifically, when the scraping device moves to the right, the rotating member 30 rotates to the left due to the friction force to the left, and at this time, the moving member 40 is driven to move to the left, and the moving member 40 presses the protruding portion 41a at the left end of the second swinging member 41, so that the left end of the second swinging member 41 is pressed down and the right end is tilted up. The wiper member 20 at the left end is further caused to be pressed down close to the glass surface for wiping operation, and the wiper member 20 at the right end is caused to be tilted away from the glass surface for non-operation.

When the moving member 40 moves backward, the first arc-shaped structure 47 drives the second arc-shaped structure 41c to slide relative to the first arc-shaped structure 21a, so as to drive the second swinging member 41 to swing.

Further, as shown in fig. 11, the moving member 40 is divided into a left portion connected to the rotating member 30 and a right portion slidably connected to the second swinging member 41, and the right portion is shaped to match the shape of the second swinging member 41, so as to slide with respect to the second swinging member 41 and press the second swinging member 41.
