Fig. 5 is a schematic view of another example of the transmission frame 40 according to the embodiment of the present application.

As shown in fig. 1 to 5, the embodiment of the present application provides a scraping apparatus, which includes a scraping body and a transmission frame 40.

The two opposite sides of the scraping surface 10 of the scraping body are respectively provided with a scraping strip 30, and the scraping surface 10 is provided with a first perforation. The binding surface of the wiping body and the article to be cleaned is the wiping surface 10, only the wiping strip 30 can be arranged on the wiping surface 10, a user sprays water on the surface of the article by using a spray can to soften dirt, and then the wiping strip 30 wipes off the water and the dirt together; in addition, a wiping material 20 such as a sponge or a rag may be additionally provided on the scraping surface 10, and the wiping material 20 is used to wipe the water stain, and then the scraping strip 30 is used to scrape the water stain, thereby improving the cleaning effect.

The transmission frame 40 comprises a translation frame 42 movably arranged in the eraser body and a connecting arm 43 which is connected with the translation frame 42 and the front end of which corresponds to the position of the first perforation, and the front end of the connecting arm 43 is provided with a friction block 50 positioned outside the first perforation. The friction block 50 is used to contact the surface of the article to generate a friction force, which can be applied to the translation frame 42 through the connecting arm 43, and the driving frame 40 switches the operation state of the two scraping strips 30.

The specific switching process is as follows: when the wiping body moves on the object for cleaning, the friction block 50 drives the transmission frame 40 to move backwards relative to the wiping surface 10 under the action of friction force with the surface of the object, the transmission frame 40 further drives the wiping strip 30 located at the front side in the advancing direction to be away from the surface of the object without wiping work, and drives the wiping strip 30 located at the rear side in the advancing direction to be close to the object for wiping work.

The scraping device in the embodiment of the present application, in which the driving frame 40 is driven by only one connecting arm 43 to perform the switching action of the scraping strip 30, can solve the problem that the driving frame 40 is easily deflected and jammed, and is specifically embodied in that: firstly, the probability of the deviation of the transmission frame 40 is smaller, and because only one connecting arm 43 is arranged on the scraping device in the embodiment of the application, compared with the scraping device with a plurality of connecting arms 43, the probability that one connecting arm 43 contacts the uneven parts such as flaws and potholes on the surface of an article is relatively smaller, so that the probability of the deviation of the transmission frame 40 is reduced; secondly, even if the object surface is in an uneven position such as a flaw and a hollow, the transmission frame 40 is driven to integrally move through the connecting arm 43, so that the action consistency can be easily realized, and the situation that one connecting arm 43 moves and other connecting arms 43 do not move under the condition of a plurality of connecting arms 43 does not occur, so that the action consistency of the transmission frame 40 in the embodiment of the application is relatively easy to control, and the situation that the transmission frame 40 is inclined and clamped can be avoided.

As shown in fig. 2 and 3, in an embodiment, the translation frame 42 is a hollow frame-shaped structure, and includes two pressing blocks 421 disposed opposite to each other and a connecting beam 422 connecting the two pressing blocks 421; the connecting arm 43 is located between the two pressing blocks 421.

The translation frame 42 in this embodiment is mainly formed by two pressing blocks 421 and two connecting beams 422 connecting the two pressing blocks 421, and the two pressing blocks 421 and the two connecting beams 422 are connected end to form a quadrilateral frame.

Alternatively, the structure of the translational frame 42 may be rectangular, square, trapezoidal, or the like.

Further, since there is only one connecting arm 43 in the present application, in order to balance the translational frame 42 during the operation, it is preferable that the connecting arm 43 is located at a middle position of the translational frame 42, that is, the connecting arm 43 is located between the two pressing blocks 421.

In the embodiment, the structure of the translation frame 42 and the layout mode of the connecting arm 43 on the translation frame 42 are limited, the structure of the translation frame 42 is simple and easy to implement, and the layout mode of the connecting arm 43 on the translation frame 42 also better ensures the balance of the translation frame 42 during action.

In other embodiments, the translation frame 42 may also have an X-shape, a grid-like structure, and the like, and correspondingly, the connecting arm 43 is located at the middle position of the structures.

As shown in fig. 2 and 3, in one embodiment, the connecting arm 43 is disposed adjacent to one of the pressing blocks 421.

When two wipers need to be attracted together with magnetic force to scrape a glass object, the wipers need to provide enough installation space for arranging the magnetically attracting members. Therefore, in the present embodiment, the connecting arm 43 located between the two pressing blocks 421 is disposed in an offset manner, that is, the connecting arm 43 is disposed adjacent to one of the pressing blocks 421, so as to avoid the hollow portion of the translational frame 42 for installing the magnetic attraction member.

The scraping device in the embodiment can make full use of the internal space of the scraping body, and the structural design is more compact and reasonable.

As shown in fig. 4, in an embodiment, the transmission frame 40 further includes a swing bracket 41 stacked below the horizontal moving frame 42 and hinged to the wiper body, two wiper strips 30 are respectively connected to two opposite sides of the swing bracket 41, and the horizontal moving frame 42 swings by horizontally pressing the swing bracket 41, so that the wiper strip 30 located at the front side in the traveling direction tilts and the wiper strip 30 located at the rear side in the traveling direction leans against the article.

In this embodiment, the swing bracket 41 is additionally arranged on the transmission frame 40, and the translation frame 42 is used for translating and pressing the swing bracket 41 to switch the working states of the two scraping strips 30, so that the structure is simple and easy to implement, and the long-time stable operation of the transmission frame 40 is ensured.

Alternatively, a hinged seat may be disposed on the wiper body, the swing bracket 41 is rotatably disposed on the wiper body through the hinged seat, two ends of the swing bracket 41 are respectively provided with one scraping strip 30, and the scraping strips 30 may be mounted on the swing bracket 41 through mounting grooves. The swinging of the swinging bracket 41 is translationally pressed by the translation frame 42, so that one of the scraping strips 30 is tilted back away from the surface of the article without scraping work, and the other scraping strip 30 is extended and pressed against the surface of the article for scraping work.

Alternatively, the translational frame 42 may be directly in transmission connection with the swing bracket 41, so that the translational frame 42 can be made to horizontally press the swing bracket 41, and the specific manner may be implemented by a guide structure.

Optionally, the translational frame 42 may also be indirectly connected to the swing bracket 41 in a transmission manner, for example, a gear set or a lever may be further added between the translational frame 42 and the swing bracket 41.

As shown in fig. 5, in one embodiment, the translation frame 42 performs translational pressing on the swing bracket 41 through a guide structure; the guide structure includes: a first guide surface 425 provided on the translational frame 42 and a second guide surface 411 provided on the swing bracket 41, the first guide surface 425 being slidable on the second guide surface 411 so that the translational frame 42 can be swung by pressing the swing bracket 41 during translation.

As mentioned above, the translation frame 42 and the swing frame 41 may be directly connected by a guide structure, which is defined in the present embodiment. The guide structure is a structure for transmitting force, and can transmit and convert the longitudinal force and the transverse force back and forth, that is, can transmit the transverse force of the translational frame 42 to the longitudinal force of the swinging bracket 41, so that the translational frame 42 can press the swinging bracket 41 to swing downwards when translating transversely.

Specifically, the guide structure includes: a first guide surface 425 provided on the translation frame 42, and a second guide surface 411 provided on the swing bracket 41.

Alternatively, the first guide surface 425 and the second guide surface 411 may be inclined planes or arc surfaces.

As shown in fig. 5, in an embodiment, the pressing block 421 is provided with a roller 424 for rolling along the inner wall of the wiper body, the pressing block 421 is provided with a second through hole 423, and the edge of the roller 424 can abut against the second guide surface 411 through the second through hole 423.

As mentioned above, the translational frame 42 is movably disposed in the eraser, and the translational frame 42 needs to be translated relative to the eraser, so as to press the swing bracket 41 to swing. Therefore, in the present embodiment, in order to reduce the frictional resistance between the translational frame 42 and the wiping body and make the translational movement of the translational frame 42 relative to the wiping body smoother, the roller 424 for rolling along the inner wall of the wiping body is disposed on the pressing block 421, so that the resistance to the movement of the translational frame 42 relative to the wiping body can be significantly reduced.

Further, as described above, since the first guide surface 425 of the translation frame 42 and the second guide surface 411 of the swing bracket 41 slide relative to each other, so that the translation frame 42 can be swung by pressing the swing bracket 41 during translation, in such a case, when the translation frame 42 is translationally pressed against the swing bracket 41, there is substantially a certain frictional resistance between the first guide surface 425 and the second guide surface 411, and therefore, in order to reduce this frictional resistance, the second penetration hole 423 is provided in the pressing block 421, and the rim of the roller 424 passes through the second penetration hole 423 to be abutted against the second guide surface 411, so that the translation frame 42 is slidably contacted with the second guide surface 411 by the roller 424, and compared with the "surface" contact between the first guide surface 425 and the second guide surface 411, the roller 424 is contacted with the second guide surface 411 by the "point" or the "line", so that the sliding contact area between the translation frame 42 and the swing bracket 41 is reduced, and the resistance of the pan frame 42 when the pan holder 41 is pressed in translation is reduced.

In this embodiment, the roller 424 added to the translational frame 42 has a "dual-purpose" function, which further reduces the production and processing costs of the scraping device.

As shown in fig. 5, in one embodiment, the first guide surface 425 or the second guide surface 411 is provided with a protrusion 426 for reducing sliding friction.

In order to reduce the sliding friction force between the first guide surface 425 and the second guide surface 411, the protruding structure 426 may be provided on the first guide surface 425 or the second guide surface 411 as in the present embodiment by reducing the sliding contact area between the first guide surface 425 and the second guide surface 411.

In this embodiment, the protrusion 426 may be disposed on an area not covered by the roller 424, so as to reduce the sliding friction between the first guide surface 425 and the second guide surface 411 in the area.

Alternatively, the raised structures 426 may be ribs or bumps.

Fig. 6 is an exploded view of the translational frame 42 and the connecting arm 43 according to the embodiment of the present application.

As shown in fig. 6, in an embodiment, the connecting arm 43 includes a post 432 and a mounting seat 431 for mounting the friction block 50, the translational frame 42 is provided with a plug hole 427, and the post 432 is inserted into the plug hole 427 to connect the translational frame 42 with the connecting arm 43.

The embodiment further defines a specific structure of the connecting arm 43, which has a plate-shaped mounting seat 431 formed integrally for mounting the friction block 50, and further defines a connection mode of the connecting arm 43 and the translational frame 42, and the connecting arm is socket-connected through the upright post 432.

In one embodiment, the connecting arm 43 is elastically and telescopically coupled to the translation frame 42.

In this embodiment, the connecting arm 43 is elastically and telescopically connected with the translational frame 42, so that the connecting arm 43 can also axially displace relative to the translational frame 42, and after the rubbing body is applied to the surface of the article, the elastic connecting arm 43 can drive the friction block 50 to be better applied to the surface of the article.

Alternatively, the connecting arm 43 is elastically and telescopically connected with the translation frame 42, and a spring may be used, or the connecting arm 43 itself is made of an elastic material, such as rubber.

It should be noted that, when the connecting arm 43 is elastically and telescopically connected with the translational frame 42, the upright post 432 and the inserting hole 427 only have a guiding and positioning function in practice, and the connecting function of the translational frame 42 and the connecting arm 43 is reduced.

Alternatively, the scraping device can be composed of a single scraping body or two scraping bodies, and the difference is whether the object to be cleaned needs to be cleaned simultaneously on the inner surface and the outer surface. For example, to clean glass as the example, scraping device comprises two bodies of wiping this moment, and during the use, two bodies of wiping are located the inside and outside both sides of glass respectively to adsorb together through magnetic force, the user can drive another and be located outdoor body of wiping and remove simultaneously through removing one body of wiping at indoor, can accomplish the inside and outside both sides of glass simultaneously clean, clean efficient and need not carry out outdoor operation. When cleaning articles such as mirrors, furniture and the like, because only one side surface of the article needs to be cleaned, the scraping device consists of a single wiping body which wipes the surface of the article by adopting reciprocating motion so as to realize cleaning.
