Fig. 5-12 are exploded views of a multi-scraper scraping device 100 according to embodiments of the present disclosure.

As shown in fig. 5, an embodiment of the present application provides a multi-scraper scraping apparatus, including: the gear transmission device comprises a shell 1, a support 3 movably arranged in the shell 1, and a gear transmission assembly arranged in the shell 1, wherein a plurality of scraping pieces (such as the scraping pieces 2-1 and the scraping pieces 2-2 in figure 5) are arranged on the support 3 and are positioned on two opposite sides outside the shell 1. When the scraping device with the plurality of scraping parts moves along the surface of the object to be cleaned, the gear transmission assembly drives the support part 3 to move, so that the scraping parts positioned in front of the moving direction in the plurality of scraping parts are far away from the surface of the object to be cleaned in the moving process, and the scraping parts positioned behind the moving direction in the plurality of scraping parts are close to the object to be cleaned and can perform the erasing work.

In the embodiment of the application, when the scraping device with multiple scraping pieces is used for cleaning an object to be cleaned, when the scraping device with multiple scraping pieces moves from a certain position on the side A of the object to be cleaned to a certain position on the side B of the object to be cleaned for cleaning and wiping, the gear transmission assembly drives the supporting piece to move, so that the scraping piece 2-1 on the rear side of the scraping device in the moving process is close to the surface of the object to be cleaned for scraping the object to be cleaned, and the scraping piece 2-2 in front of the moving direction is far away from the surface of the object to be cleaned for temporarily stopping scraping. When the direction of the multi-scraper scraping device needs to be switched in the moving process, namely when the multi-scraper scraping device moves from a certain position on the side B of the object to be cleaned to a certain position on the side A of the object to be cleaned for cleaning and wiping, the rear scraper 2-2 is close to the surface of the object to be cleaned to perform scraping action on the object to be cleaned, and the scraper 2-1 in the moving direction is far away from the surface of the object to be cleaned to temporarily stop the scraping operation. The user uses the scraping device of above-mentioned many scrapers to treat that clean object implements the cleaning operation in-process and need not to transfer the scraping device of many scrapers just can diversely scrape and treat clean object, and it is more simple and convenient to operate, can improve user's efficiency of cleaning to can not form and clean the dead angle treating clean surface, thereby be favorable to improving and clean the effect. In addition, because the scraping piece for wiping is positioned behind the moving direction, after the multi-scraping-piece scraping device wipes the object to be cleaned, water stains or other residual stains left on the surface of the object to be cleaned can be further removed by utilizing the scraping piece behind the moving direction, so that the wiping effect is better.

It is understood that the movement of the support 3 by the gear transmission assembly in the embodiment of the present application may refer to: the gear transmission assembly drives the support member 3 to swing. For example, such that one side of the support 3 is inclined toward the object to be cleaned. Of course, the side of the support 3 inclined toward the object to be cleaned is used for performing the scraping work.

It should be noted that, in the embodiment of the present application, when the scraping device with multiple scraping members is attached to the object to be cleaned, the surface of the housing 1 attached to the object to be cleaned is referred to as: the outer surface or outer surface of the housing 1 (which may also be referred to as the front surface or the abutting surface of the housing 1) is not limited in the embodiment of the present application, and therefore, when the scraping device with multiple scraping members is abutted against the object to be cleaned, the surface of the housing 1 facing away from the object to be cleaned (which may also be referred to as the back surface of the housing 1) may be inside the housing 1.

The inside of the housing 1 in the embodiment of the present application can be understood as follows: inside the housing 1. The housing 1 in the embodiment of the present application can be understood as follows: outside the housing 1.

Furthermore, due to the difference in the moving direction, it is opposite whether the same bar is located "forward" or "rearward" in the moving direction, for example if moving in the direction of pointing a to B, the scraping member 2-1 is located "rearward" in the moving direction, and the scraping member 2-2 is located "forward" in the moving direction, then the scraping member 2-2 is away from the surface of the object to be cleaned during the scraping process, and the scraping member 2-1 is close to the surface of the object to be cleaned, so that the wiping operation is performed. For example, if the wiper member 2-2 is moved in the direction B toward a, the wiper member 2-2 is located "behind" the moving direction and the wiper member 2-1 is located "in front" the moving direction, and the wiper member 2-1 is located away from the surface of the object to be cleaned and the wiper member 2-2 is located close to the surface of the object to be cleaned during wiping, and wiping is performed.

It can be seen from fig. 1 and 2 that the two opposite sides of the housing 1 can be referred to as the two opposite long sides of the housing 1, in other words, the two opposite sides are perpendicular to the moving direction of the scraping device with multiple scraping elements.

It should be noted that fig. 1 to 5 only show 2 scraping members, that is, 1 scraping member is disposed on each of two opposite sides of the housing 1, but in practical process, 2 or more than 2 scraping members may be disposed on each of two opposite sides of the housing 1, which is not limited in the embodiment of the present application.

If 2 or more than 2 scraping pieces are arranged on each of two opposite sides of the housing 1, the 2 or more than 2 scraping pieces on the same side are either far away from the surface of the object to be cleaned or close to the surface of the object to be cleaned, which is not limited in the embodiment of the present application.

In a possible implementation, the above-mentioned oppositely arranged plurality of scrapers are arranged symmetrically, and furthermore, if 2 or more than 2 scrapers are arranged on each side, it is ensured that no wiping position is occupied.

In the embodiment of the present application, the gear transmission assembly drives the supporting member 3 to swing, so that the surface of the scraping member, which is located in front of the moving direction, of the plurality of scraping members away from the object to be cleaned in the moving process may be retracted into the scraping device by the gear transmission assembly driving the scraping member located in front of the moving direction, or may be folded or pushed down by other forms, for example, so that the scraping member located in front of the moving direction can be away from the surface to be cleaned, and thus the scraping member located in front of the moving direction can be prevented from working.

Accordingly, the gear transmission assembly drives the supporting member 3 to swing, so that the scraping member located behind the plurality of scraping members in the moving direction is close to the surface of the object to be cleaned to perform the scraping operation, the scraping member located behind the moving direction may be driven to extend toward the surface to be cleaned, or the scraping member located behind the moving direction may be raised (straightened) in another form, so that the scraping member located behind the moving direction is close to the surface to be cleaned, thereby performing the scraping operation. The form of driving the scraping members behind the moving direction to conduct scraping work is not limited, and any scraping member can be switched between working and non-working.

Exemplarily, the support 3 oscillates with respect to the axis of the scraping device of the plurality of scrapers by an oscillation angle in the range of 5 ° to 25 °. This is because an excessively small angle may cause the wiper member on the front side in the wiping travel direction to contact the surface of the object to be cleaned to thereby make the wiper overhead, and an excessively large angle may affect the installation space in the housing 1. The gear transmission component is arranged on the shell 1 and moves in the same direction with the wiper, one side of the gear transmission component is provided with a friction piece with friction force different from that of the wiper, the other side of the gear transmission component is connected with the supporting piece 3 and drives the supporting piece 3 to rotate, and the movement stroke of the gear transmission component is in direct proportion to the rotation angle of the supporting piece 3.

The scraping piece in the embodiment of the application is used for removing residual stains on the surface of an object to be cleaned. As an example, the scraping member in the embodiment of the present application may be a scraping strip.

In the embodiment of the present application, in order to better wipe the surface of the object to be cleaned, as shown in fig. 6, the outer part 101 of the housing 1 further has a fixing region 1014 (for example, a hatched portion in fig. 6), and the fixing region 1014 is used for fixing the wipe. The wipers are located between wipers arranged on opposite sides of the housing 1. For example, the wipe may be a wipe or a sponge or the like. The wipe may be in two pieces as shown in fig. 6.

To facilitate periodic replacement of the cleaning wipe, the wipe may be removably secured to the securement region. The embodiment of the present application does not specifically limit the detachable connection manner. Further, the size of the wipe can be selected based on the need.

It is worth mentioning that in a free state, the front end parts of the scraping pieces on the left side and the right side can be slightly higher than the wiping surface of the wiping object, so that a certain moving space is reserved for the scraping pieces. The wipes are removably secured to the securement region as described below and exemplified in fig. 6.

For example, as shown in fig. 6 and 7, fig. 6 shows the structure of the outer surface 101 of the housing 1, and it can be seen that in order to achieve better wiping of the objects to be cleaned, the outer surface 101 of the housing 1 may be formed in a "convex" shape or stepped shape, i.e., the middle portion is protruded on opposite sides, i.e., the middle portion 1011 of the outer surface 101 of the housing 1 is higher on opposite sides, and the portions (the edge portions 1012 and 1013) of the outer surface 101 of the housing 1 other than the middle portion are lower than the middle portion 1011. And attachment area 1014 is located on edge 1012 and edge 1013. Thus, after the wiper is fixed on the fixing areas on the two sides, the wiping surface of the wiper can be flush with the joint surface of the middle part of the shell 1, thereby being convenient for users to wipe.

The edge portions 1012 and 1013 can have a plurality of mounting holes (e.g., mounting hole 1014-1, mounting hole 1014-2, mounting hole 1014-3, and mounting hole 101404) in addition to the through hole 1015 for allowing the friction member to pass through, and a wipe can be placed on the edge portions 1012 and 1013 in the fastening region 1014 if desired, and then passed through the wipe with a fastening member to be snapped into the mounting hole to removably attach the wipe to the outer surface 101 of the housing 1. It should be understood that only 4 mounting holes are shown in fig. 7. Wherein, the mounting holes 1014-1, 1014-2 are symmetrically arranged, and the mounting holes 1014-3, 1014-4 are symmetrically arranged. The installation reliability of the wiper can be ensured by symmetrically arranging the installation holes on the same side.

The shape of the mounting hole and the fixing member may be set as required. For example, the mounting hole may be rectangular, and the shape in which the fixing member is caught in the mounting hole may be tapered.

Of course, the wipe may be removably secured to the securing region 1014 in other ways, such as by providing the securing region 1014 with a plurality of ribs opposite to each other, passing the wipe through the securing region when the wipe is in the securing region, and then removably securing the wipe to the exterior surface 101 of the housing 1 using a fastener that mates with the plurality of ribs.

By removably mounting the wipe to the exterior surface 101 of the housing 1, the wipe can be easily replaced during subsequent use.

In a possible embodiment, the gear transmission assembly comprises a gear assembly, and a sliding block 5 and a sliding member 6 connected with the gear assembly, when the multi-scraper wiping device moves along the surface of the object to be cleaned, the sliding block 5 moves backwards relative to the moving direction under the action of the friction force of the friction member and the surface of the object to be cleaned, so as to drive the sliding member 6 to translate through the gear assembly, the sliding member 6 drives the support member 3 to swing when translating, so that the front end of the support member 3 is far away from the surface of the object to be cleaned, and the rear end of the support member 3 is close to the surface to be cleaned for wiping work.

It is worth mentioning that the front end of the support 3 and the rear end of the support 3 are also opposite concepts, the front end of the support 3 being fitted with a scraper in front of the direction of movement. The rear end of the support 3 is fitted with a wiper located behind in the direction of movement. For example, if the scraper 2-2 is located "behind" the moving direction, the rear end of the support 3 is mounted with the scraper 2-2, or the end mounted with the scraper 2-2 is regarded as the rear end of the support 3. If the scraper 2-1 is located "forward" in the direction of movement, the front end of the support 3 is fitted with the scraper 2-1, or the end fitted with the scraper 2-1 is considered to be the front end of the support 3.

In a possible implementation, the first face of the sliding block 5 is provided with a friction element, the second face of the sliding block 5 is connected with a gear assembly, the first and second faces being arranged facing away from each other. When the scraping device moves along the surface of the object to be cleaned, the friction piece can generate friction force with the surface of the object to be cleaned, and the sliding block 5 moves backwards relative to the moving direction under the action of the friction force.

It will be appreciated that when the scraping device is moved along the surface of the object to be cleaned, the friction member and the surface of the object to be cleaned generate a friction force, under which the sliding block 5 is moved backwards relative to the moving direction. In other words, the friction member drives the support member 3 to move through the gear transmission assembly. I.e. the friction element, via the gear assembly, drives the support element 3 in oscillation with respect to the axis of the scraping means of the plurality of scraping elements.

In one possible implementation, the friction member should have a sufficient coefficient of friction to generate sufficient friction, and should also be resistant to wear and soaking. The application does not limit the specific form of the friction member. In the embodiment of the application, the friction member is a friction block. For example, the friction block may be made of plastic, rubber, resin, leather, or the like.

Preferably, the friction block may be made of cowhide. The cowhide has proper friction coefficient, is resistant to abrasion and soaking, and has long service life.

It will be appreciated that the amount of displacement of the friction member relative to the housing 1 is limited and controllable, and in the embodiment of the application, the friction member is moved by the friction force to the maximum displacement and is held at the maximum displacement, which brings the plurality of scraping members to the preset position and is held at the preset position. In the preset position, one scraping piece of the plurality of scraping pieces is retracted to be out of work, and the other scraping piece is extended to be capable of scraping work.

In the embodiment of the application, when the scraping device with multiple scraping pieces is used for cleaning an object to be cleaned, the friction piece can rub against the surface of the object to be cleaned to generate friction force, so that when the scraping device with multiple scraping pieces moves from a certain position (for example, an edge) on the side a of the object to be cleaned to a certain position (for example, an edge) on the side B of the object to be cleaned, under the action of the friction force, the rear scraping piece 2-1 is close to the surface of the object to be cleaned to perform scraping action on the object to be cleaned, and the scraping piece 2-2 in front of the moving direction is far away from the surface of the object to be cleaned to temporarily stop scraping work. When the scraping device with multiple scraping pieces moves from a certain position (such as an edge) on the side B of the object to be cleaned to a certain position (such as an edge) on the side A of the object to be cleaned in the cleaning and wiping process, the rear scraping piece 2-2 is close to the surface of the object to be cleaned so as to perform the scraping action on the object to be cleaned, and the scraping piece 2-1 in the moving direction is far away from the surface of the object to be cleaned so as to temporarily stop the scraping work. The user uses the scraping device of above-mentioned many scrapers to treat that clean object implements the cleaning operation in-process and need not to transfer the scraping device of many scrapers just can diversely scrape and treat clean object, and it is more simple and convenient to operate, can improve user's efficiency of cleaning to can not form and clean the dead angle treating clean surface, thereby be favorable to improving and clean the effect. In addition, because the scraping piece for wiping is positioned behind the moving direction, after the multi-scraping-piece scraping device wipes the object to be cleaned, water stains or other residual stains left on the surface of the object to be cleaned can be further removed by utilizing the scraping piece behind the moving direction, so that the wiping effect is better.

In a possible implementation, the friction element is removably associated with the sliding block 5. This facilitates the replacement of the friction element or the fixing of the friction element on the sliding block 5. It will be appreciated that the friction of the friction member is different from the friction of the wipe.

With continued reference to fig. 6 or fig. 7, in order to enable the friction member to contact with the surface of the object to be cleaned, the housing 1 is provided with a through hole 1015 opposite to the sliding block 5, through which the friction member protrudes out of the housing 1, and when the scraping device of the multiple scraping members moves along the surface of the object to be cleaned, the friction member can contact with the surface of the object to be cleaned through the through hole, so as to generate friction force with the surface of the object to be cleaned during the moving process, and the generated friction force is enough to enable the sliding block 5 to move backward relative to the abutting surface of the housing 1 and the object to be cleaned, and further the supporting member 3 is driven to swing along the center of the housing 1 through the gear transmission assembly so that the scraping members located forward in the moving direction among the multiple scraping members are far away from the surface of the object to be cleaned, and the scraping members located backward in the moving direction are close to, and can wipe the surface of the object to be cleaned to perform the wiping work.

It should be noted that, in the embodiment of the present application, the distance between the scraping member located behind the moving direction and the surface of the object to be cleaned is not limited, as long as in an actual process, the scraping member located behind the moving direction is close to the surface of the object to be cleaned, so that the wiping operation can be performed.

Referring to fig. 8 and 9, for the structure of the translation member 6 provided in the embodiment of the present application, a side portion of the translation member 6 forms a pressing surface, and the translation member 6 presses the support 3 through the pressing surface.

Optionally, a plurality of smooth protrusions are arranged on the connection surface of the translation member 6 and the housing 1. Therefore, the friction force between the sliding part 6 and the shell 1 can be reduced, and the sliding part 6 and the shell 1 can slide relatively conveniently.

In one possible implementation, the gear assembly in the embodiment of the present application includes: the driving component is arranged on the second surface, the rotating shaft 9 is arranged in the shell, the rotating shaft 9 is provided with a first gear 7, the first gear 7 is meshed with a first rack 61 arranged on the translation piece 6 to realize transmission, and the driving component can drive the rotating shaft 9 to move in the process that the sliding block 5 moves backwards relative to the moving direction.

It will be appreciated that the first gear 7 or the second gear 8 described below may be movably mounted on the rotating shaft 9 to facilitate mounting, and further, the first gear 7 may be mounted on the rotating shaft 9 at a position opposite to the position of the first rack 61 to facilitate the engagement of the first gear 7 with the first rack 61 provided on the translation member 6.

As an example, as shown in fig. 5, the driving part includes: a second rack 51 arranged on the second surface, and a second gear 8 arranged on the rotating shaft 8, wherein the second gear 8 is meshed with the second rack 51 to realize transmission. Therefore, in the process that the sliding block 5 moves backwards relative to the moving direction, the second rack 51 moves backwards along with the sliding block 5, and the second rack 51 is meshed with the second gear 8, so that the second gear 8 drives the rotating shaft 9 to rotate, the first gear 7 is driven to move in the rotating process of the rotating shaft 9, and the purpose of driving the translation member 6 to translate can be achieved because the first gear 7 is meshed with the first rack 61 arranged on the translation member 6.

The second gear 8 is mounted on the rotating shaft 9 at a position opposite to the position of the second rack 51, so that the second gear 51 is engaged with the second rack 51 provided on the slide block 5.

Illustratively, the first rack 51 is detachably fixed to the second surface of the sliding block 5. For example, the second surface of the sliding block 5 has a mounting hole, and the first rack 51 also has an opening corresponding to the mounting hole of the sliding block 5, so that the first rack 51 can be detachably fixed on the second surface of the sliding block 5 by using a screw. Similarly, the second rack 61 is detachably fixed to the translation member 6. It should be understood that the second rack 61 is removably fixed to the outer surface of the translation member 6, and the inner surface of the translation member 6 is opposite to the outside of the casing 1, in other words, the inner surface of the translation member 6 is arranged opposite to the outside of the casing 1.

It will be appreciated that, under the effect of the friction force, the hysteresis movement of the sliding block 5 takes the form of a reverse movement, so that the first rack 51 fixed on the second face of the sliding block 5 moves. Since the first gear 7 is engaged with the first rack 51, the first rack 51 moves to move the first gear 7. And the first gear 7 will drive the rotation shaft 9 to rotate. The rotation of the rotating shaft 9 drives the second gear 8 to move, and the second gear 8 is engaged with the second rack 61, so that the second rack 61 moves along with the movement of the second gear 8. Subsequently, the second rack 61 drives the translation member 6 to move (for example, translate), and the translation member 6 drives the support member 3 to swing during translation, so as to realize the alternate work of the plurality of scraping members.

As another example, the driving part includes: the processing component is used for controlling the motor to work under the condition that the sliding block 5 is determined to move backwards relative to the moving direction, and the motor can drive the rotating shaft 9 to move. The processing means comprise a position sensor arranged on the second side of the sliding block 5 for detecting a movement signal of the sliding block 5, and a control device. The control device is used for sending a control instruction to the motor according to the movement signal acquired by the position sensor so as to control the motor to work through the control instruction. When the motor is operated, the motor can drive the rotating shaft 9 to move (for example, rotate). It should be understood that the control device in the embodiment of the present application may be a CPU or the like, and this is not limited in the embodiment of the present application.

It should be noted that, in the embodiment of the present application, when the scraper on one side is required to work, the driving component controls the rotating shaft 9 to rotate towards the scraper.

For example, if moving in the direction of pointing B towards a, the scraping member 2-1 is moved away from the surface of the object to be cleaned during scraping, while the scraping member 2-2 is moved closer to the surface of the object to be cleaned, and the wiping operation is performed, the drive member controls the rotation shaft to rotate towards the scraping member 2-2, so that the translation member 6 presses the support member 3 to bring the scraping member 2-2 closer to the surface of the object to be cleaned. If moving in the direction of pointing B according to a, the scraping member 2-2 is moved away from the surface of the object to be cleaned during scraping, and the scraping member 2-1 is moved closer to the surface of the object to be cleaned, and the wiping operation is performed, the drive means controls the rotating shaft to rotate towards the scraping member 2-1, so that the translating member 6 presses the support member 3 to bring the scraping member 2-1 closer to the surface of the object to be cleaned.

It can be seen from fig. 1 and 2 that the two opposite sides of the housing 1 can be referred to as the two opposite long sides of the housing 1, in other words, the two opposite sides are perpendicular to the moving direction of the scraping device with multiple scraping elements.

As another embodiment of the present application, in order to avoid that the translation distance of the translation member 6 is too large, or the translation member tilts, the scraping device in the embodiment of the present application further includes a limiting assembly, and the limiting assembly is used for limiting the translation distance of the translation member 6 and maintaining the translation state.

As an example, the stop assembly comprises: a first limit part arranged on the upper surface of the shell 1 and a second limit part arranged on the upper surface of the translation piece 6 and matched with the first limit part. When the translation limiting mechanism is installed, the translation distance of the translation piece 6 can be limited and the translation state can be kept through the matching of the first limiting part and the second limiting part.

For example, as shown in fig. 5 and 10, the first stopper portion is a through hole 10 provided on the upper surface of the housing 1. As shown in fig. 9, the second limiting portion is a rib 62 disposed on the upper surface of the translation member 6, and the rib 62 can extend into the through hole 10 and prevent the translation member 6 from falling off from the through hole 10 on the upper surface of the housing 1. Or for example, the second limiting part is a through hole arranged on the upper surface of the translation member 6, and the first limiting part is a convex rib arranged on the shell 1.
