Therefore, the technical scheme that this application embodiment provided can promote the simple operation nature when cleaning surfaces such as glass, ground, wall.

The following describes exemplary embodiments of a scraping device and a scraping device provided in embodiments of the present application, respectively, with reference to the accompanying drawings.

Scraping device

Fig. 1 shows a schematic structural diagram of a scraping apparatus 100 provided in an embodiment of the present application, and for convenience of explanation, only the parts related to the embodiment of the present application are shown. As shown in fig. 1, the scraping apparatus 100 includes a base 10, a driving assembly 20, and double scrapers 30 (corresponding to two scrapers 30). The double scrapers 30 are arranged at intervals on opposite sides of the base 10, and the front ends of the double scrapers 30 face the same side as the wiping surface (a plane indicated by a in fig. 1) of the base 10.

It should be noted that the surface of the base 10 close to the surface to be cleaned (e.g., the plane indicated by b in fig. 1) is referred to as the wiping surface of the base 10.

In the present embodiment, the drive assembly 20 is located between two wipers 30.

In a possible implementation, the two scraping members 30 can be arranged parallel to each other. This can make the cleaning effect when the scraping device scrapes along a certain direction and then scrapes reversely better.

In the embodiment of the present application, the base 10 functions to support the driving assembly 20.

Optionally, each scraping element 30 may include one or more scraping strips, or each scraping element 30 may be a scraping plate, or may be any other scraping element (e.g., a brush head) meeting the actual use requirement, and may be determined according to the actual use requirement, and the embodiment of the present invention is not limited thereto.

Optionally, the scraping element 30 may be made of plastic or rubber, or may be made of any other material (for example, plastic material) meeting the actual use requirement, which may be determined according to the actual use requirement, and the embodiment of the present application is not limited.

Alternatively, the rear end portion to the front end portion of the scraping member 30 is tapered to improve the scraping effect.

As shown in fig. 1, the driving assembly 20 includes a roller 21 and two transmission assemblies 22 disposed at both sides of the roller 21, and the roller 21 is in transmission connection with the double scraping member 30 through the two transmission assemblies 22, respectively.

In a possible implementation, with reference to fig. 1, the wiping surface of the base 10 is provided with a through hole 11, through which hole 11 the cambered part of the roller 21 passes and protrudes from the wiping surface.

Since the roller 21 protrudes from the wiping surface of the base 10 and is exposed to the surface to be cleaned, when the wiping apparatus 100 moves to wipe the surface to be cleaned, the roller 21 comes into contact with the surface to be cleaned, and a frictional force is generated between the roller 21 and the surface to be cleaned. Further, the roller 21 rolls in the traveling direction (i.e., the wiping direction) of the wiping apparatus 100 by the friction force with the surface to be cleaned.

Further, the roller 21 can drive the scraping member 30 located at the front side in the traveling direction away from the surface to be cleaned and not work during the rolling process through the transmission assembly 22, and drive the scraping member 30 located at the rear side in the traveling direction close to the surface to be cleaned for the scraping work.

It will be appreciated that figure 1 is a schematic view of the scraping apparatus in an unused state. Accordingly, fig. 2 and 3 show a schematic view of the structure of the scraping device in a state of use. The operation of the scraping device provided by the embodiment of the present application will be further described with reference to fig. 2 and 3.

As shown in fig. 2 and 3, when the scraping device 100 moves to scrape the surface to be cleaned, the roller 21 rolls along the traveling direction of the scraping device 100 under the action of the friction force with the surface to be cleaned, for example, when the scraping device 100 moves in the direction (to the right) as shown by the straight line arrow in fig. 2, and accordingly the roller 21 rolls along the direction shown by the arc arrow in fig. 2, so that the roller 21 drives the scraping member 30 located at the front side in the traveling direction (for example, the right scraping member 30) away from the surface to be cleaned to be inoperative, and drives the scraping member 30 located at the rear side in the traveling direction (for example, the left scraping member 30) close to the surface to be cleaned to perform the scraping work through the transmission assembly 22. The scraping device 100 in fig. 2 and 3 differs slightly in structure, as will be seen below.

It should be noted that when the wiping operation needs to be reversed, the wiping device 100 can be directly moved for reversing without twisting the wiping device 100 for reversing. Illustratively, when the scraping device 100 is moved to the left (opposite to the traveling direction in fig. 2) to scrape the surface to be cleaned, the roller 21 rolls to the left under the friction force with the surface to be cleaned, so that the roller 21 drives the scraping member 30 on the left side away from the surface to be cleaned and does not work through the transmission assembly 22, and drives the scraping member 30 on the right side close to the surface to be cleaned to perform the scraping work. Compared with the process of scraping by rotating the glass wiper to change the direction in the related art, the scraping device provided by the embodiment of the application does not need to rotate, and can be used for reversing to scrape, so that a user can use the device more conveniently.

It should be noted that, the above is exemplified by the scraping device 100 moving to the left or to the right for performing the scraping operation, and it is to be understood that, in practical use, the scraping device 100 can move in any direction on the surface to be cleaned for performing the scraping operation, which is not limited by the embodiment of the present application.

It should be noted that, in the embodiment of the present application, the movement manner of the scraping member 30 is not limited as long as the scraping member 30 can be switched between the operating state and the non-operating state. In one aspect, the driving of the scraping element 30 away from the surface to be cleaned may be the driving of the scraping element 30 towards the inside of the scraping device 100, or may be performed in other ways, such as folding the scraping element 30, so that the front end of the scraping element 30 can be away from the surface to be cleaned, and thus the scraping element 30 can be made inoperative. On the other hand, the driving scraping member 30 is close to the surface to be cleaned for scraping, and the driving scraping member 30 may be protruded toward the surface to be cleaned, or may be in other forms, such as raising the scraping member 30, so that the front end of the scraping member 30 is close to the surface to be cleaned, thereby performing the scraping operation.

In one possible implementation, the wiping surface of the base 10 may be free of wipes. In this case, the scraping device performs a scraping operation on the surface to be cleaned by the scraping member on the rear side in the traveling direction during use, for example, scraping water stains on glass by the scraping member.

In another possible implementation, a wipe may be disposed on the wiping surface of the base 10. In this case, during the use of the scraping device 100, the surface to be cleaned can be wet-wiped by the wiper, and then the surface to be cleaned can be further scraped by the scraping element at the rear side of the traveling direction, so that the surface to be cleaned can be better cleaned.

Alternatively, the wipe may be a wipe or sponge or the like. In addition, the arrangement position of the wiping object can be determined according to the actual use requirement. Illustratively, the wipe may include two portions, one disposed on each end of the wiping surface of the base 10.

By way of example and not limitation, the surface to be cleaned may include, but is not limited to, a glass surface, a blackboard surface, a floor surface, a billboard surface, and the like. It will be appreciated that the scraping means may be a glass wiper, which can be used to scrape clean a glass surface. Of course, the scraping device can also be used for scraping and cleaning other surfaces such as a desktop, a wall surface, a ground surface and a blackboard surface, and the application does not limit the scraping device.

In the embodiment of the present application, the scraping device 100 moves to scrape the surface to be cleaned, which may be a user manually moves the scraping device 100 to scrape the surface to be cleaned, or an internal motor drives the scraping device 100 to move to scrape the surface to be cleaned, and this application is not limited thereto.

In one possible implementation, referring to fig. 4, each of the dual wipers 30 includes a wiper strip 30a and a wiper strip mount 30b for mounting the wiper strip 30 a. Wherein the scraping bar mounting seat 30b is provided with a mounting groove, and the scraping bar 30a can be mounted on the scraping bar mounting seat 30b through the mounting groove.

In one possible implementation, referring to fig. 2-4, each of the two transmission assemblies 22 includes a first link 22a and a second link 22b, one end of the first link 22a is connected to the roller 21, and the other end of the first link 22a is hinged to one end of the second link 22 b. The other end of the second link 22b is connected to one scraper 30 of the double scrapers 30.

Alternatively, the second link 22b and the scraper 30 may be connected by various possible means, including but not limited to the following four connection means:

first, referring to fig. 4, for each transmission assembly 22, the other end of the second link 22b is provided with an inclined slider structure c, and each scraper 30 of the double scrapers 30 is provided with a chute structure d (e.g., a chute structure d is provided on the scraper bar mounting seat 30 b). The second link 22b is slidably connected to the scraper member 30 via the slider structure c and the chute structure d.

With the scraping device in this connection manner, the rolling of the roller 21 can drive the first link 22a and the second link 22b in the transmission assembly 22 to move, so that the slider structure c of the second link 22b slides in the inclined groove structure d of the scraping member 30, and thus drives the scraping member 30 on one side to move downwards and the scraping member 30 on the other side to move upwards. This type of connection corresponds to the scraping device 100 of fig. 2 described above.

Referring back to fig. 2, when the scraping device 100 moves to scrape the surface to be cleaned, the roller 21 rolls along the traveling direction of the scraping device 100 under the action of the friction force with the surface to be cleaned, for example, when the scraping device 100 moves along the direction (right direction) indicated by the straight arrow in fig. 2, accordingly, the roller 21 rolls along the direction indicated by the arc arrow in fig. 2, the roller 21 rolls to drive the first link 22a to swing to the left and the second link 22b to move to the left, and the slider structure of the second link 22b slides to the left in the chute structure of the scraping member 30, thereby pressing the scraping member 30 on the left to move downward and driving the scraping member 30 on the right to move upward. It is thereby achieved that the roller 21 drives the scraping member 30 located at the rear side in the direction of travel (the left-side scraping member 30) close to the surface to be cleaned for scraping work via the transmission assembly 22, and drives the scraping member 30 located at the front side in the direction of travel (the right-side scraping member 30) away from the surface to be cleaned for non-working.

In the second way, for each transmission assembly 22, the other end of the second link 22b is provided with a chute structure, and each scraper 30 of the double scrapers 30 is provided with an inclined slider structure. The second link 22b is slidably connected to the scraper 30 by a slider structure and a chute structure.

Since the second link 22b and the scraping member 30 are slidably connected through the slider structure and the chute structure in the similar manner as the first manner, the specific driving principle can be referred to the first manner, and will not be described herein.

In a third way, for each transmission assembly 22, the other end of the second link 22b is provided with a projection and each scraper 30 of the double scrapers 30 is provided with a notch. The second link 22b is engaged with the scraper 30 by the projection and the recess.

In a fourth way, for each transmission assembly 22, the other end of the second link 22b is provided with a notch and each scraper 30 of the double scrapers 30 is provided with a projection. The second link 22b is engaged with the scraper 30 by means of a projection and a notch.

In a similar manner to the third and fourth connections, the other end of the second link 22b engages with the scraper 30 via the protrusion and the notch. The scraping device of this connection corresponds to the scraping device in fig. 3 described above.

Of course, the second link 22b and the scraper 30 can be connected in other ways, which is not limited in the embodiment of the present application.

Alternatively, the first link 22a and the roller 21 may be connected by various possible ways, including but not limited to the following two ways:

first, referring to fig. 4, for each transmission assembly 22, one end of the first link 22a is provided with a first hinge hole e, and the plane portion of the roller 21 is provided with a first hinge column 21 a. The first link 22a is hinged to the roller 21 through a first hinge hole e and a first hinge post 21 a.

In the second connection mode, for each transmission assembly 22, one end of the first link 22a is provided with a first hinge post, and the plane portion of the roller 21 is provided with a first hinge hole. The first link 22a is hinged to the roller 21 through the first hinge hole and the first hinge post.

Of course, the first link 22a and the roller 21 may be connected in other ways, which is not limited in the embodiment of the present application.

Alternatively, the roller 21 and the base 10 may be connected by various possible ways, including but not limited to the following two ways:

in a possible implementation, referring back to fig. 1, the side of the base 10 opposite to the wiping surface is provided with a second hinge post 12, and referring again to fig. 4, the planar portion of the roller 21 is further provided with a second hinge hole 21 b. Wherein, the second hinge post 12 stretches into the second hinge hole 21b, and the second hinge hole 21b is sleeved outside the second hinge post 12, so as to realize that the roller 21 is rotatably connected with the base 10 through the second hinge post 12 and the second hinge hole 21 b.

In this way, the base 10 is rotatably connected with the second hinge hole 21b of the roller 21 through the second hinge column 12 thereof, so that the base 10 supports the roller 21, and thus the base 10 functions as a support driving assembly.

Further, the roller 21 can rotate around the second hinge post 12 on the base 10 within a certain angle range, and then the roller 21 rotates to drive the transmission assembly 22 to move, and then the transmission assembly 22 moves to drive the scraping element 30 at the front side of the traveling direction to be away from the surface to be cleaned and not to be operated, and drive the scraping element 30 at the rear side of the traveling direction to be close to the surface to be cleaned for scraping work.

In another possible implementation, the base 10 is provided with a second hinge hole on the side opposite to the wiping surface, and the planar portion of the roller 21 is provided with a second hinge post. The second hinge post stretches into in the second hinge hole, and outside the second hinge post was located to second hinge hole cover promptly, realized that gyro wheel 21 and base 10 rotate through second hinge post and second hinge hole and be connected.

Of course, the roller 21 and the base 10 may be connected in other ways, which is not limited in the embodiments of the present application.

Fig. 5 shows a schematic view of the overall assembly of the scraping apparatus 100 provided by the embodiment of the present application. As shown in fig. 5, the scraping device 100 further comprises a top cover 50. Wherein the drive assembly 20 and the double scraper 30 are housed in a cavity formed by the cover 50 and the base 10.

It should be noted that the top cover 50 is detachably mounted on the base 10, and the connection manner between the top cover 50 and the base 10 is not limited in the embodiment of the present application.
