[0002] Due to the long-term influence of the internal and external environments, some dust and impurities will remain on the surface of the glass window, which not only affects the beauty of the glass window but also is not conducive to indoor lighting. Therefore, the glass needs to be cleaned frequently. The appearance of the glass cleaner has provided great convenience for the cleaning work of the glass window.

[0003] Existing glass cleaners usually have a wiping cloth and a squeegee arranged on their wiping surfaces. The wiping cloth is arranged on the wiping surface for scrubbing the glass surface, and the squeegee is arranged at the edge of the wiping surface for scraping the water stains on the glass surface. During use, the user moves the glass cleaner in the direction with the wiping cloth in front and the squeegee behind to clean the glass.

When the glass cleaner needs to change direction during movement, for the triangular glass cleaner, usually only one squeegee is provided, and the user needs to manually rotate the glass cleaner to continue cleaning the glass surface in the reverse direction. For the rectangular glass cleaner, usually two squeegees are arranged in a seesaw form on the opposite sides of the rectangular glass cleaner, and the alternation of the squeegees is used to achieve the switching of the forward and reverse directions, resulting in inflexible use of the glass cleaner.

Detailed implementation manners

[0083] Next, the technical solutions of the present application will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0084] In the description of the present application, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0085] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "coupled" shall be construed broadly. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0086] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0087] In daily life, a glass cleaner is used to clean the glass surface, i.e., the surface to be scraped. Usually, a wiping cloth and a scraping strip are provided on the wiping surface of the existing glass cleaner. The wiping cloth is used to scrub the surface to be scraped, and the scraping strip is used to scrape the water stains on the surface to be scraped. Since the glass cleaner needs to change its direction during the wiping process of the surface to be scraped, the user needs to manually rotate the glass cleaner to change the direction and continue cleaning, or the user realizes the switching of the forward and reverse directions by alternately using two scraping strips arranged in a seesaw form on the opposite side of the glass cleaner. The use mode of this type of glass cleaner is not flexible, which limits the operation of the user when wiping the surface to be scraped and affects the user experience. At the same time, due to the single form of the glass cleaner to change its direction, wiping dead corners are easily formed during use, resulting in incomplete glass cleaning.

[0088] The present application provides a scraping mechanism of a scraping device. The scraping device includes a main body, and the main body includes a wiping surface. The scraping mechanism includes: a scraping assembly, the scraping assembly is movably arranged on the main body of the scraping device so that a part of the scraping assembly can extend out of or retract into the wiping surface; and a driving assembly, the driving assembly is movably connected to the main body of the scraping device, a receiving space for the driving assembly is provided on the wiping surface, the driving assembly moves in any direction along the wiping surface in the receiving space, the driving assembly is used to abut against the surface to be scraped, and when the scraping device moves in the forward direction, the driving assembly moves backward under the action of the frictional force between the driving assembly and the surface to be scraped, so as to drive a part of the scraping assembly close to the driving assembly to extend out of the wiping surface to perform scraping work.

[0089] In practical applications, the glass wiper, i.e., the scraping device, can be set in various shapes, such as circular, oval, triangular, rectangular, polygonal or irregular shapes, etc. For the convenience of description below, the scraping device is taken as an example of a triangle, but the present application is not limited thereto. In addition, in practical applications, the shape of the wiping surface may or may not be the same as the shape of the scraping device. In the present application, the shape of the wiping surface is taken as an example of being the same as the shape of the scraping device, that is, the scraping device is triangular and its wiping surface is also set as triangular; for another example, the scraping device is rectangular and its wiping surface is also set as rectangular, but the present application is not limited thereto.

[0090] The scraping assembly is set to be extendable or retractable from the wiping surface so that during use, the scraping assembly performing the scraping work is in the extended state and the remaining scraping assemblies are in the retracted state. In some embodiments, the scraping assembly extends from the wiping surface under the action of the driving assembly and retracts under the action of an external force. For example, after removing the frictional force provided by the driving assembly in the forward direction relative to the scraping device, the user presses the scraping device against the surface to be scraped, so that the scraping assembly retracts under the action of the surface to be scraped and the external pressing force. In other embodiments, the scraping assembly extends from the wiping surface under the action of the driving assembly and retracts under the action of the scraping strip reset mechanism described in detail later. For example, after removing the frictional force provided by the driving assembly in the forward direction relative to the scraping device, the scraping assembly automatically resets under the action of the scraping strip reset mechanism.

[0091] In some embodiments, the main body of the scraping device includes a wiping surface, and a receiving space for the driving assembly is provided on the wiping surface. In one example, the driving assembly is disposed in the receiving space and its end is flush with the wiping surface. In another example, the driving assembly is disposed in the receiving space and its end protrudes from the wiping surface so that when the scraping device moves, there is a large frictional force between the driving assembly and the surface to be scraped. In addition, the wiping surface is usually disposed at the bottom of the scraping device, the wiping cloth is disposed on the wiping surface, and the scraping assembly is disposed on the periphery of the wiping surface to facilitate the user to perform the scraping operation.

[0092] As described above, the driving component can move in any direction along the wiping surface within the accommodating space. When the scraping device moves in the forward direction, the driving component moves backward under the action of the frictional force between the driving component and the surface to be scraped, so as to drive a part of the scraping assembly close to the driving component to extend out of the wiping surface. Among them, any direction of the wiping surface refers to the direction within the 360-degree range in the plane where the wiping surface is located. The forward direction of the scraping device refers to the movement track direction when the scraping device works. The forward direction is not limited to the direction perpendicular to the scraping assembly, and the forward direction also includes the direction at a certain angle to the scraping assembly. The scraping assembly close to the driving component means that when the scraping device moves in the forward direction, the component of the frictional force between the driving component and the surface to be scraped can be decomposed into a force acting on the scraping assembly to make it extend out of the wiping surface for a scraping assembly, and then this scraping assembly is defined as the scraping assembly close to the driving component.

[0093] Taking the triangular scraping device as an example, the forward direction does not specifically refer to the vertical direction along the perpendicular line between the apex angle of the triangle and its corresponding scraping assembly and moving towards its apex angle. The forward direction also includes the inclined direction at a certain angle to the side where the scraping assembly is located. For example, the inclined direction of moving towards the other side of the triangle rather than the apex angle corresponding to the side where the scraping assembly is located. Specifically, please refer to Figure 1, which is a simplified schematic diagram of the relationship between the advancing direction of the scraping device and the scraping mechanism provided in the embodiments of the present application. As shown in the figure, taking the scraping device as an equilateral triangle as an example, the three vertices of the triangle are A, B, and C respectively, and the three perpendicular bisectors AD, BE, and CF of the triangle intersect at the midpoint O. The scraping components are arranged along each side, respectively represented as AB, AC, and BC. The movement of the scraping device in the direction perpendicular to the scraping component, that is, the movement of the scraping device along AD, BE, or CF towards their respective vertices, is called the movement in the vertical direction. For example, when the scraping device moves along AD towards vertex A, the driving component moves backward under the action of the frictional force between it and the surface to be scraped, the driving component approaches the scraping component BC and drives the scraping component BC to extend out of the wiping surface. The movement of the scraping device at a certain angle with the side where the scraping component is located, that is, the movement of the scraping device towards the sides AB, AC, or BC of the triangle rather than towards the vertices A, B, or C, is called the movement in the inclined direction. For example, when the scraping component is arranged on the BC side of the triangle, the movement of the scraping device towards the other side AB or AC rather than vertex A is called the movement in the inclined direction. When the scraping device moves towards side AB, the driving component moves backward under the action of the frictional force between it and the surface to be scraped. If the component of this frictional force can be decomposed into a force acting on BC to make it extend out of the wiping surface for the scraping component BC, the driving component drives the scraping component BC to extend out of the wiping surface. If the component of this frictional force can be decomposed into a force acting on AC to make it extend out of the wiping surface for the scraping component AC, the driving component drives the scraping component AC to extend out of the wiping surface. If the component of this frictional force can be decomposed into forces acting on AC and BC to make them extend out of the wiping surface for both the scraping component BC and AC, the driving component drives the scraping components AC and BC to extend out of the wiping surface.

[0094] In a specific example, based on the characteristics of the equilateral triangle, when a force is applied to the scraping device along CF to make it move towards side AB, the driving component moves backward under the action of the frictional force between it and the surface to be scraped. The component of this frictional force acts on the scraping components BC and AC, that is, the driving component approaches the scraping components BC and AC and drives the above two scraping components to extend out of the wiping surface. When a force is applied to the scraping device along BE to make it move towards side AC, the driving component moves backward under the action of the frictional force between it and the surface to be scraped. The component of this frictional force acts on the scraping components AB and BC, that is, the driving component approaches the scraping components AB and BC and drives the above two scraping components to extend out of the wiping surface. When the force applied to the scraping device is within the area enclosed by ACF and towards AB, or when the force applied to the scraping device is within the area enclosed by ABE and towards AC, the component of this frictional force only acts on BC, that is, the driving component approaches the scraping component BC and drives it to extend out of the wiping surface. The working modes of other scraping components are similar and will not be elaborated here.

[0095] The scraping mechanism of the present application is provided with a driving component capable of moving in any direction along the wiping surface and a scraping component used in cooperation with the driving component, so that the driving component can drive a part of the scraping component close to it to extend out of the wiping surface for wiping work, which is convenient for users to operate flexibly during use.

[0096] In some embodiments, the driving component is movably connected to the main body of the scraping device, so that the driving component can move in any direction along the wiping surface within the accommodating space. It should be noted that there are various ways for the driving component to be movably connected to the main body, as long as the driving component can achieve 360-degree movement in the direction parallel to the wiping surface within the accommodating space. In some embodiments, the driving component and the main body are connected in cooperation with a universal structure to enable the driving component to move in any direction along the wiping surface within the accommodating space. In one example, the driving component is spherically hinged to the main body. For example, a first spherical structure is provided at one end of the driving component, and a first opening part matching the first spherical structure is provided on the main body, and the first spherical structure of the driving component is accommodated in the first opening part so that the first spherical structure moves in the first opening part. Or, a first opening part is provided at one end of the driving component, and a first spherical structure matching the first opening part is provided on the main body. In addition, the first opening part is set as a closed circular structure, or the first opening part is surrounded by a plurality of baffles at intervals to improve the smoothness of the movement of the first spherical structure in the first opening part and reduce the occurrence of jamming. In another example, the driving component is connected to the main body through a first elastic member. For example, the first elastic member is set as a rod-shaped structure. The driving component is connected to the main body through an elastic rod-shaped structure, and the elastic rod-shaped structure realizes the swinging of the driving component in any direction within the accommodating space. In other embodiments, the driving component is slidably connected to the main body to enable the driving component to move in any direction along the wiping surface within the accommodating space. For example, the driving component is provided with a slider, and a sliding groove is provided on the main body, and the slider slides in the sliding groove to realize the movement of the driving component in any direction along the wiping surface within the accommodating space.

[0097] In some embodiments, a friction structure is provided at one end of the driving component for abutting against the surface to be scraped to enhance the friction force between the driving component and the surface to be scraped. For example, the friction structure is set as leather, a rubber part or a silica gel part fixed on the driving component, which can increase the friction force and prevent the driving component from scratching the surface to be scraped at the same time.

[0098] During use, the driving component abuts against the surface to be scratched, so that when the scratching device moves in the forward direction, the driving component moves backward under the action of the frictional force between the driving component and the surface to be scratched. In some embodiments, the driving component is arranged to be movable in a direction perpendicular to the wiping surface. After the driving component abuts against the scratching surface, by applying an external force to the scratching device, the driving component can be telescoped in a direction perpendicular to the wiping surface. On the one hand, the frictional force between the wiping cloth and the surface to be scratched is increased to improve the cleaning ability. On the other hand, when the scratching device moves, the frictional force between the driving component and the surface to be scratched is increased to improve the scratching ability of the scratching component.

[0099] In some embodiments, the driving component includes a first transmission unit and a friction unit. The first transmission unit is movably connected to the main body. The friction unit is used to abut against the surface to be scratched. The friction unit is movably connected to the first transmission unit so that the friction unit can move in a direction perpendicular to the wiping surface. As described above, the friction structure can be arranged on the friction unit so that when the driving component abuts against the surface to be scratched, the friction structure on the friction unit abuts against the surface to be scratched.

[0100] In some embodiments, the friction unit is provided as an elastic member so that the friction unit can elastically expand and contract in a direction perpendicular to the wiping surface. Specifically, when the driving assembly abuts against the surface to be scratched, the elastic member deforms under the action of an external force, so that the wiping surface of the scratching device is in close contact with the surface to be scratched. When the external force is removed, the elastic member resets under the action of its own elastic force. In some other embodiments, the friction unit and the first transmission unit are connected by a second elastic member so that the friction unit can elastically expand and contract in a direction perpendicular to the wiping surface. Specifically, an elastic connecting member is provided between the friction unit and the first transmission unit. When the driving assembly abuts against the surface to be scratched, the friction unit squeezes the elastic connecting member under the action of an external force, so that the wiping surface of the scratching device is in close contact with the surface to be scratched. When the driving assembly leaves the surface to be scratched, the elastic connecting member drives the friction unit to reset under the action of its own elastic force. In one example, the friction unit includes a first connecting member. A connecting through hole is provided on the first transmission unit. The first connecting member is used to abut against the surface to be scratched and is movably arranged in the connecting through hole. The second elastic member is clamped between the first connecting member and the first transmission unit so that the first connecting member can elastically expand and contract in a direction perpendicular to the wiping surface. In one example, the first connecting member passes through the connecting through hole and is clamped on the first transmission unit to prevent the friction unit from detaching from the first transmission unit during elastic expansion and contraction. In addition, in order to prevent the second elastic member clamped between the first connecting member and the first transmission unit from detaching during the telescopic movement of the friction unit, in some embodiments, a first clamping portion is provided on one side of the first connecting member facing the first transmission unit, and one end of the second elastic unit is clamped on the first clamping portion provided on the first connecting member. In some other embodiments, a second clamping portion is provided on one side of the first transmission unit facing the first connecting member, and one end of the second elastic unit is clamped on the second clamping portion provided on the first transmission unit. In yet another embodiment, a first clamping portion is provided on one side of the first connecting member facing the first transmission unit, and a second clamping portion is provided on one side of the first transmission unit facing the first connecting member. The second elastic member is clamped on the first clamping portion and the second clamping portion. Wherein, the second elastic member can be provided as a spring, and the first clamping portion and the second clamping portion are provided as grooves or protrusions.

[0101] In addition, the driving assembly is used to drive a part of the scraping assembly to extend out of the scraping surface. In some embodiments, the scraping assembly and the driving assembly are not directly connected. When the scratching device moves in the forward direction, the driving assembly moves backward under the action of the frictional force between it and the surface to be scratched. While the driving assembly moves backward, it contacts the scraping assembly to drive a part of the scraping assembly to extend out of the wiping surface. In some other embodiments, the scraping assembly and the driving assembly are connected. When the scratching device moves in the forward direction, the driving assembly moves backward under the action of the frictional force between it and the surface to be scratched to drive a part of the scraping assembly close to the driving assembly to extend out of the wiping surface for scraping work. The connection between the driving assembly and the scraping assembly improves the transmission stability between the driving assembly and the scraping assembly.

[0102] Based on this, in some embodiments, the driving component includes a transmission member and a second transmission unit. One end of the transmission member is movably connected to the main body, and the other end of the transmission member is used to abut against the surface to be scraped. The transmission member and the scraping assembly are connected by the second transmission unit, and the second transmission unit is used to convert the backward movement of the transmission member into the movement of the scraping assembly towards the wiping surface direction, so that the transmission member drives a part of the scraping assembly close to it to extend out of the wiping surface through the second transmission unit to perform scraping work. Among them, the second transmission unit is used to connect the transmission member and the scraping assembly. In some embodiments, the second transmission unit is set as a connecting rod, and the transmission member drives the part of the scraping assembly away from the advancing direction towards the wiping surface through the connecting rod so that a part of the scraping assembly extends out of the wiping surface. For example, the transmission member pushes the side of the scraping assembly away from the advancing direction to lift and move towards the wiping surface through the connecting rod, and then extends out of the wiping surface. In some examples, the scraping assembly slides towards the wiping surface under the push of the connecting rod so that one end of the scraping assembly away from the connecting rod extends out of the wiping surface. In other examples, the scraping assembly warps under the push of the connecting rod so that one end of the scraping assembly away from the connecting rod extends out of the wiping surface. For example, the scraping assembly is provided with a rotating shaft, and the scraping assembly is movably arranged in the main body through the rotating shaft, so that when the transmission member drives the scraping assembly through the connecting rod, the side of the scraping assembly away from the rotating shaft moves towards the wiping surface so that a part of the scraping assembly extends out of the wiping surface.

[0103] In practical applications, the connecting rod is used to transmit force between the scraping assembly and the transmission member. In some embodiments, the connecting rod is movably connected to one of the scraping assembly and the transmission member, and the connecting rod is fixedly connected to the other. The transmission member drives a part of the scraping assembly to extend out of the wiping surface through the connecting rod to perform scraping work. For example, the connecting rod is movably connected to the scraping assembly and fixedly connected to the transmission member, or the connecting rod is movably connected to the transmission member and fixedly connected to the scraping assembly. Again, the movable connection can be a spherical hinge or a socket connection. In addition, the connecting rod can be set as a fixed connecting rod with a constant length or a telescopic connecting rod with a variable length such as an elastic telescopic connecting rod. When the scraping device includes a plurality of scraping assemblies, setting the elastic telescopic connecting rod can provide a change in distance between the scraping assembly and the transmission member to avoid the situation that other scraping assemblies restrict its movement when the scraping assembly extends or retracts from the wiping surface.

[0104] In some embodiments, the movable connection is a spherical hinge. For example, one of the side where the connecting rod is connected to the scraping assembly and the scraping assembly is provided with a second spherical structure, and the other is provided with a second opening portion that cooperates with the second spherical structure; or one of the side where the connecting rod is connected to the transmission member and the transmission member is provided with a third spherical structure, and the other is provided with a third opening portion that cooperates with the third spherical structure. Specifically, in the case where the connecting rod is fixedly connected to the transmission member and movably connected to the scraping assembly, in one example, the side of the connecting rod connected to the scraping assembly is provided with a second spherical structure, and the scraping assembly is provided with a second opening portion that cooperates with the second spherical structure; in another example, the scraping assembly is provided with a second spherical structure, and the side of the connecting rod connected to the scraping assembly is provided with a second opening portion that cooperates with the second spherical structure. In the case where the connecting rod is fixedly connected to the scraping assembly and movably connected to the transmission member, the side of the connecting rod connected to the transmission member is provided with a third spherical structure, and the transmission member is provided with a third opening portion that cooperates with the third spherical structure; in another example, the transmission member is provided with a third spherical structure, and the side of the connecting rod connected to the transmission member is provided with a third opening portion that cooperates with the third spherical structure.

[0105] In some other embodiments, the movable connection is a socket connection. For example, the scraping assembly or the transmission member is provided with a first receiving groove, and the connecting rod is socketed in the first receiving groove, and the outer diameter of the connecting rod is smaller than the inner diameter of the first receiving groove. Specifically, in one example, the connecting rod is fixedly connected to the transmission member and movably connected to the scraping assembly, wherein the scraping assembly is provided with a first receiving groove, and the connecting rod is socketed in the first receiving groove, and the outer diameter of the connecting rod is smaller than the inner diameter of the first receiving groove. In another example, the connecting rod is fixedly connected to the scraping assembly and movably connected to the transmission member, wherein the transmission member is provided with a first receiving groove, and the connecting rod is socketed in the first receiving groove, and the outer diameter of the connecting rod is smaller than the inner diameter of the first receiving groove.

[0106] In some other embodiments, the connecting rod is movably connected to the scraping assembly, and the connecting rod is movably connected to the transmission member, and the transmission member drives a part of the scraping assembly to extend out of the wiping surface through the connecting rod to perform scraping work. For example, the movable connection is a spherical hinge or a socket connection.

[0107] In some embodiments, the above-mentioned movable connections are all spherical hinges. For example, one of the side where the connecting rod is connected to the scraping assembly and the scraping assembly is provided with a fourth spherical structure, and the other is provided with a fourth opening portion that cooperates with the fourth spherical structure; and one of the side where the connecting rod is connected to the transmission member and the transmission member is provided with a fifth spherical structure, and the other is provided with a fifth opening portion that cooperates with the fifth spherical structure.

[0108] In some other embodiments, the connecting rod is spherically hinged to one of the scraping assembly and the transmission member, and the connecting rod is sleeved on the other. For example, one of the side where the connecting rod is connected to the scraping assembly and the scraping assembly is provided with a sixth spherical structure, and the other is provided with a sixth opening portion that cooperates with the sixth spherical structure; and the transmission member is provided with a second receiving groove, the connecting rod is sleeved in the second receiving groove, and the outer diameter of the connecting rod is smaller than the inner diameter of the second receiving groove. Another example is that one of the side where the connecting rod is connected to the transmission member and the transmission member is provided with a seventh spherical structure, and the other is provided with a seventh opening portion that cooperates with the seventh spherical structure; and the scraping assembly is provided with a third receiving groove, the connecting rod is sleeved in the third receiving groove, and the outer diameter of the connecting rod is smaller than the inner diameter of the third receiving groove.

[0109] In still some other embodiments, the above-mentioned movable connections are all sleeve connections. For example, the scraping assembly is provided with a fourth receiving groove, the transmission member is provided with a fifth receiving groove, the connecting rod is sleeved in the fourth receiving groove and the fifth receiving groove, the outer diameter of the connecting rod is smaller than the inner diameter of the fourth receiving groove, and the outer diameter of the connecting rod is smaller than the inner diameter of the fifth receiving groove.

[0110] Please refer to Figures 2 to 5 , Figure 2 which is a schematic three-dimensional structure diagram of the scraping mechanism of the scraping device provided in the embodiment of the present application from the first perspective, Figure 3 is Figure 2 a schematic three-dimensional structure diagram of the scraping mechanism shown from the second perspective, Figure 4 is Figure 2 an exploded view of the drive assembly in the scraping mechanism shown from the third perspective, Figure 5 is Figure 2Exploded view of the drive assembly in the scraping mechanism shown from the fourth perspective. As shown in the figure, the scraping mechanism 1 includes a scraping assembly 2 and a drive assembly 3. Among them, the drive assembly 3 includes a transmission member 31 and a connecting rod 32, and the transmission member 31 is connected to the scraping assembly 2 through the connecting rod 32. Among them, the transmission member 31 includes a first transmission unit 311 and a friction unit 312. One end of the first transmission unit 311 is provided with a first spherical structure 3111, and a first opening 511 that cooperates with the first spherical structure 3111 is provided on the main body of the scraping device. The first spherical structure 3111 is received in the first opening 511, and a connecting through hole 3112 is further provided at the other end of the first transmission unit 311. The friction unit 312 includes a first connecting member 3121. The first connecting member 3121 is movably disposed in the communication through hole 3112. The first connecting member 3121 passes through the connecting through hole 3112 and is clamped to the first transmission unit 311 by, for example, a clamping member (not shown) to prevent the friction unit 312 from detaching from the first transmission unit 311 when elastically expanding and contracting. A groove 3122 is provided on one side of the first connecting member 3121 facing the first transmission unit 311, and a boss 3113 is provided on one side of the first transmission unit 311 facing the first connecting member 3121. One end of a spring (not shown) is received in the groove 3122, and the other end is stuck on the boss 3113. A friction structure (not shown) is further provided on one end portion 3123 of the friction unit 312 for abutting against the surface to be scraped. In this example, the connecting rod 32 is movably connected to both the scraping assembly 2 and the transmission member 31. Among them, the connecting rod 32 is set as a fixed connecting rod with a constant length. A sixth spherical structure 323 is provided on the side of the connecting rod 32 connected to the scraping assembly 2, and a sixth opening 252 that cooperates with the sixth spherical structure 323 is provided on the scraping assembly 2. A second receiving groove 3114 is provided at one end of the first transmission unit 311, and one end of the connecting rod 32 is sleeved in the second receiving groove 3114. In addition, a rotating shaft 251 is provided on one side of the scraping assembly 2 close to the sixth opening 252, and both ends of the rotating shaft 251 are mounted in the main body of the scraping device.

[0111] When using the scraping device, the friction structure on the friction unit 312 abuts against the surface to be scraped. Under the action of the pressing force of the user towards the surface to be scraped, the first connecting member 3121 on the friction unit 312 moves in the connecting through hole 3112 in a direction away from the surface to be scraped, the spring is in a compressed state, the friction structure on the friction unit 312 is in close contact with the surface to be scraped and the wiping surface of the scraping device is in close contact with the surface to be scraped. When the scraping device is operated by the user along Figure 2When the forward direction indicated by the arrow, such as moving along the forward direction M of the vertex or along the forward directions N or P of the side where the scraping component is located, under the action of friction, the first spherical structure 3111 of the first transmission unit 311 moves in the first opening 511 and at the same time pushes the connecting rod 32 sleeved therein through the second accommodating groove 3114. The sixth spherical structure 323 of the connecting rod 32 arranged in the sixth opening 252 of the scraping component 2 pushes the scraping component 2. At this time, the rotating shaft 251 arranged on the scraping component 2 rotates, causing the side of the scraping component 2 away from the connecting rod 32 to tilt, so that a part of the scraping component 2 extends out of the wiping surface.

[0112] It should be noted that, according to Figure 1 and its description, when the forward directions N or P enable the components of the friction force to act on multiple scraping components, the transmission process of multiple scraping components extending out of the wiping surface is similar to the above-mentioned transmission process of a single scraping component extending out of the wiping surface, which will not be elaborated here. In addition, to clearly show the connection between the transmission member 31 and the scraping component 2, only one connecting rod 32 is shown in the figure. Those skilled in the art should be clear that the connecting rods 32 on the driving component 3 can be arranged corresponding to the scraping component 2, and can be one or more, which will not be elaborated here.

[0113] In some embodiments, the scraping component is provided with a squeegee reset mechanism so that after the friction force provided by the driving component in the forward direction relative to the scraping device is removed, the scraping component can retract under the action of the squeegee reset mechanism, improving the user experience.

[0114] In some embodiments, the squeegee reset mechanism includes a third elastic member. The scraping component is movably arranged on the main body through the third elastic member so that when the friction force provided by the driving component in the forward direction relative to the scraping device is removed, the scraping component is reset under the action of the third elastic member. For example, when the scraping component extends out of the wiping surface, the third elastic member is in a stressed state. When the friction force provided by the driving component in the forward direction relative to the scraping device is removed, the third elastic member returns to its initial state according to its own characteristics. Furthermore, the scraping component is reset under the action of the elastic force provided by the third elastic member when it returns to the initial state.

[0115] In some embodiments, the scraping assembly includes a third transmission unit and a wiper strip unit. The third transmission unit acts on the wiper strip unit, and the wiper strip unit is connected to the main body through a third elastic member. When the scraping device moves in the forward direction, the driving assembly drives a part of the wiper strip unit close to the driving assembly to extend out of the wiping surface through the third transmission unit to perform scraping work. When the frictional force provided by the driving assembly in the forward direction of the scraping device is removed, the wiper strip unit resets under the action of the third elastic member. In one example, the third transmission unit is connected to the wiper strip unit; in another example, the third transmission unit abuts against the wiper strip unit; in yet another example, the third transmission unit and the wiper strip unit are an integral body. It should be noted that the present application does not limit the connection relationship between the third transmission unit and the wiper strip unit, as long as the third transmission unit can transmit force to the wiper strip unit.

[0116] As described above, in one example, the third transmission unit abuts against the wiper strip unit to avoid problems such as jamming during the telescopic movement of the scraping assembly, which may affect the user experience. Specifically, the wiper strip unit is placed on the third transmission unit and contacts the third transmission unit. In the case where the above-mentioned driving assembly includes a transmission member and a connecting rod with a spherical end, the two ends of the first side of the third transmission unit away from the wiper strip unit are provided with rotating shafts, and an opening portion matching the spherical structure is provided in the middle. The second side of the third transmission unit adjacent to the wiper strip unit abuts against the wiper strip unit, and the cross-section of the third transmission unit gradually narrows from the first side to the second side. The rotating shafts are movably mounted in the main body, and the spherical end of the connecting rod is accommodated in the opening portion. When the scraping device moves in the forward direction, the transmission member drives the third transmission unit to move through the connecting rod to drive a part of the wiper strip unit close to the transmission member to extend out of the wiping surface to perform scraping work.

[0117] In some embodiments, the wiper strip unit includes a wiper strip mounting groove and a second connecting member. The wiper strip mounting groove is used for mounting the wiper strip. The third transmission unit acts on the side of the wiper strip mounting groove away from the wiper strip. The second connecting member is provided on the side of the wiper strip mounting groove away from the wiper strip. The second connecting member is connected to the main body through a third elastic member. When the driving assembly drives a part of the wiper strip mounting groove to extend out of the wiping surface, the second connecting member moves toward the wiping surface along the main body of the scraping device and compresses the third elastic member. When the frictional force provided by the driving assembly in the forward direction of the scraping device is removed, the third elastic member drives the second connecting member to move away from the wiping surface along the main body of the scraping device to drive the wiper strip mounting groove to reset.

[0118] In one example, the second connecting member is fixedly connected to the squeegee mounting groove. In another example, the second connecting member is movably connected to the squeegee mounting groove. In yet another example, the second connecting member is integrally formed with the squeegee mounting groove. Additionally, the second connecting member is disposed on the side of the squeegee mounting groove facing away from the squeegee. In one example, the second connecting member is disposed in the middle of the side of the squeegee mounting groove facing away from the squeegee. In another example, the second connecting member is disposed at both ends of the side of the squeegee mounting groove facing away from the squeegee to improve the stability of the wiping assembly during movement.

[0119] In some embodiments, a first through hole is provided on the main body. The second connecting member passes through the first through hole and is snap-fitted with the first through hole. A third elastic member is disposed on the side where the second connecting member passes through the first through hole. For example, the third elastic member is a spring, and the spring is sleeved on the portion of the second connecting member passing through the first through hole. In some embodiments, one end of the second connecting member away from the squeegee mounting groove is snap-fitted to the main body by a screw to prevent the second connecting member from detaching from the squeegee mounting groove. In some embodiments, a gasket is disposed between one end of the second connecting member away from the squeegee mounting groove and the screw. In some embodiments, the squeegee is mounted in the squeegee mounting groove in an L shape, and during use, the squeegee can be pulled out for cleaning or replacement.

[0120] Please refer to Figure 6 and Figure 7 , Figure 6 is Figure 2 the exploded view of the wiping assembly in the wiping mechanism shown in the fifth perspective. Figure 7 is Figure 2 the exploded view of the wiping assembly in the wiping mechanism shown in the sixth perspective. As shown in the figure, the wiping assembly 2 includes a squeegee reset mechanism. In this example, the squeegee reset mechanism is set as a spring (not shown). The wiping assembly 2 includes a third transmission unit 25 and a squeegee unit 24. The third transmission unit 25 abuts against the squeegee unit 24. At both ends of the first side of the third transmission unit 25 away from the squeegee unit 24, there are rotating shafts 251 and a sixth opening 252 matching the spherical structure is provided in the middle. The second side of the third transmission unit 25 adjacent to the squeegee unit abuts against the squeegee unit 24, and the cross-section of the third transmission unit 25 gradually narrows from the first side to the second side. The rotating shafts 251 are movably mounted in the main body. Additionally, the squeegee unit 24 includes a squeegee mounting groove 241 and a second connecting member 242. The squeegee mounting groove 241 is used to mount a squeegee (not shown). The squeegee is mounted in the squeegee mounting groove 241 in an L shape. One side of the squeegee mounting groove 241 is open, and a baffle 2411 is provided on the other side. The baffle 2411 is used to press one side of the squeegee. The second connecting member 242 is integrally formed with the squeegee mounting groove 241 and is located at both ends of the side of the squeegee mounting groove 241 facing away from the squeegee. The second connecting member 242 passes through the first through hole 515 provided on the main body ( Figure 11as shown in the figure) and is clamped to the main body together with the first through hole by a screw (not shown). A spring (not shown) is sleeved on the part of the second connecting member 242 passing through the first through hole.

[0121] When using the scraping device, when the driving component drives the rotating shaft 251 provided on the scraping component 2 to rotate so that the side of the scraping component 2 away from the connecting rod 32 tilts up, causing part of the scraping component 2 to extend out of the wiping surface, the connecting rod 32 accommodated in the sixth opening 252 pushes the third transmission unit 25. The rotating shaft 251 on the first side of the third transmission unit 25 rotates and drives the second side of the third transmission unit 25 to tilt towards the wiping surface. Then, when the strip mounting groove 241 abutting on the third transmission unit 25 moves towards the wiping surface, the second connecting member 242 moves along the first through hole 515 provided on the main body towards the wiping surface and compresses the spring. Part of the strip mounting groove 241 extends out of the wiping surface so that the strip installed in the strip mounting groove 241 performs the scraping work. When the frictional force provided by the driving component in the forward direction of the scraping device is removed, the spring returns to its initial state according to its own characteristics. Under the action of the spring force, the second connecting member 242 moves along the first through hole 515 away from the wiping surface and drives the strip mounting groove 241 to move away from the surface to be scraped, thereby driving the scraping component 2 to reset.

[0122] Based on the above, the present application further provides a strip reset mechanism for a scraping component, which is applied to a scraping device. The scraping device includes a main body, and the main body includes a wiping surface. Among them, the scraping device includes a driving component for driving part of the scraping component to extend out of the wiping surface, so that when the frictional force provided by the driving component in the forward direction of the scraping device is removed, the scraping component is reset under the action of the strip reset mechanism.

[0123] It should be noted that the above strip reset mechanism is not only applicable to the scraping device including the driving structure described in the present application Figures 1 to 7 but also applicable to scraping devices including other driving structures such as rollers and swinging, which will not be elaborated here.

[0124] The present application further provides a scraping device. The scraping device includes a main body, and the main body includes a wiping surface. The scraping device further includes the scraping mechanism as described above Figures 1 to 7 Among them, the scraping mechanism includes at least one scraping component provided on the wiping surface.

[0125] Among them, the main body of the scraping device can be set in any shape, such as circular, oval, triangular, rectangular, polygonal or irregular shape, etc. The scraping components are provided as one or more, and the scraping components are arranged along the edge of the main body. For example, when the scraping device is triangular or rectangular, the scraping components are arranged along each side. Another example is that when the scraping device is circular or oval, the scraping components are arranged continuously or discontinuously along the edge.

[0126] In some embodiments, the scraping mechanism includes a first scraping component and a second scraping component that are disposed opposite to or adjacent to each other on the wiping surface. For example, when the scraping device is triangular, the first scraping component and the second scraping component are disposed on two of the sides of the triangle. Another example is that when the scraping device is rectangular, the first scraping component and the second scraping component are disposed on opposite sides of the rectangle, or the first scraping component and the second scraping component are disposed on adjacent sides of the rectangle.

[0127] When the scraping device moves in the forward direction, the driving component moves backward under the action of the frictional force between the driving component and the surface to be scraped, so as to drive a part of the first scraping component and / or a part of the second scraping component close to the driving component to extend out of the wiping surface to perform scraping work. Specifically, in the case where the first scraping component and the second scraping component are disposed adjacent to each other, when the scraping device moves in the forward direction relative to the first scraping component, the first scraping component extends out of the wiping surface or both the first scraping component and the second scraping component extend out of the wiping surface. When the scraping device moves in the forward direction relative to the second scraping component, the second scraping component extends out of the wiping surface or both the first scraping component and the second scraping component extend out of the wiping surface. In the case where the first scraping component and the second scraping component are disposed opposite to each other, when the scraping device moves in the forward direction relative to the first scraping component, the first scraping component extends out of the wiping surface. When the scraping device moves in the forward direction relative to the second scraping component, the second scraping component extends out of the wiping surface.

[0128] In other embodiments, the scraping mechanism includes a plurality of scraping components disposed around the wiping surface. For example, when the scraping device is triangular, three scraping components are disposed on the three sides of the triangle. Another example is that when the scraping device is rectangular, four scraping components are disposed on the four sides of the rectangle. When the scraping device moves in the forward direction relative to a certain scraping component, the scraping component extends out of the wiping surface or the scraping component and the scraping component adjacent to it extend out of the wiping surface.

[0129] By the above method of setting a plurality of scraping components adjacent to, opposite to, or around the wiping surface, and adopting the driving structure provided in the present application, when the user switches the direction, there is no need to manually rotate the glass wiper, and only by changing the scraping direction, a full-range scraping work can be achieved, which is convenient for the user to operate flexibly. In addition, since the scraping components are disposed adjacent to or around the wiping surface, there are no cleaning dead corners during the scraping process, and the glass can be thoroughly cleaned.

[0130] In practical applications, when the adjacent scraping components extend out of the wiping surface simultaneously as described above, it will cause a jamming phenomenon during the cleaning process. Therefore, a movable handle is provided on the main body of the scraping device. The handle is used to control the scraping device to travel in a direction perpendicular to one of the scraping components, so that only one scraping component extends out of the wiping surface during the scraping process, thereby improving the scraping efficiency. In one example, the movable handle is provided on the upper surface of the main body. In another example, the movable handle is provided on the side surface of the main body.

[0131] In some embodiments, the movable handle can adopt a universal structure, so that there is a force application point that can apply force in a direction perpendicular to one of the scraping components for main bodies of different shapes.

[0132] In some other embodiments, a cooperating portion that cooperates with the handle is provided on the main body. The handle switches among multiple force application point positions through the cooperating portion, so that the handle drives the scraping device to travel in a direction perpendicular to one of the scraping components at the corresponding force application point positions. In some embodiments, the cooperating portion is set as a hole located on the upper surface of the main body. The handle can switch positions among different holes, and the handle located in different holes is used to control the scraping device to travel in a direction perpendicular to different scraping components. In some other embodiments, the cooperating portion is set as a force application position shown on the upper surface of the main body. The handle is placed at different force application positions to control the scraping device to travel in a direction perpendicular to different scraping components through the handle. In still some other embodiments, the cooperating portion is set as a guiding groove on the upper surface of the main body. The handle is movably installed in the guiding groove, and the force application point is located in the guiding groove. The handle moves in the guiding groove to reach the force application point, and the handle drives the scraping device to travel in a direction perpendicular to one of the scraping components at the force application point. Among them, the shape of the guiding groove can be set according to the shape of the main body of the scraping device and the position of the scraping component. In some embodiments, the force application points are linearly connected to form the guiding groove, and the force application points are located at the ends of the guiding groove. For example, when the handle slides to the end of the guiding groove, the handle can apply a force perpendicular to the direction of the scraping component at this position. In some other embodiments, the guiding groove includes at least one track that is arranged at an angle to the scraping component. Among them, the shape of the track is not necessarily composed of straight lines, and there can be curves or broken lines. The angle between the guiding groove and the scraping component can be set arbitrarily as needed, as long as the handle can move in the guiding groove to reach the force application point. In practical applications, for the convenience of user operation, the force application point can be set at the end of the guiding groove. In one example, the guiding groove forms a 90-degree angle with the scraping component, and in another example, the guiding groove forms a 180-degree angle with the scraping component.

[0133] Please refer to Figure 8, which is a simplified schematic diagram of the guiding groove of the scraping device provided in the embodiment of the present application. As shown in the figure, when the wiping surface is rectangular, the guiding groove is set as an L-shaped groove, a cross-shaped groove or a diamond-shaped groove. For example, when the guiding groove is an L-shaped groove, the force application points are located at the three vertex positions of the L. When the guiding groove is a cross-shaped groove, the force application points are located at the four end positions of the cross. When the guiding groove is a diamond-shaped groove, the force application points are located at the four vertex positions of the diamond. Among them, the handle slides in the guiding groove to each force application point, and then drives the scraping device to travel in a direction perpendicular to one of the scraping components at the force application point.

[0134] Please refer to Figure 9 , which is a simplified schematic diagram of the guiding groove of the scraping device provided in another embodiment of the present application. As shown in the figure, when the wiping surface is triangular, the guiding groove includes two tracks parallel to two sides of the triangle, or the guiding groove includes three tracks parallel to the three sides of the triangle. Among them, the end of the track, that is, the vertex position of the triangle, is the force application point. The handle slides to the force application point through the above two tracks or three tracks, and then drives the scraping device to travel in a direction perpendicular to one of the scraping components at the force application point.

[0135] In the case where the main body is provided with a guiding groove, in some embodiments, the handle includes a handheld part and a connecting part. The first end of the connecting part is connected to the handheld part, and the second end of the connecting part is movably clamped in the guiding groove to prevent the handle from detaching from the guiding groove when moving in the guiding groove. Among them, the handheld part can be set in a shape convenient for the user to hold and operate, such as an arc, a circle, an ellipse, etc. In one example, the connecting part is fixedly connected to the handheld part. In another example, the connecting part is movably connected to the handheld part. For example, the connecting part and the handheld part are connected by threads, so as to facilitate the disassembly of the handheld part for separate cleaning.

[0136] In order to improve the sliding effect of the handle in the guiding groove, in one example, the second end of the connecting part includes a spherical part and an anti-detaching part. The spherical part contacts the guiding groove, and the anti-detaching part is clamped in the guiding groove. Please refer to Figure 10 , which is an exploded view of the movable handle of the scraping device provided in the embodiment of the present application. As shown in the figure, the handle 6 includes a handheld part 61 and a connecting part 62. The first end of the connecting part 62 is connected to the handheld part 61 by threads. The second end of the connecting part 62 includes a spherical part 621 and an anti-detaching part 622. In this example, the connecting part 62 is set as a rod-shaped structure. A receiving cavity 623 is provided at the second end of the connecting part. The spherical part 621 is received in the receiving cavity 623. The anti-detaching part 622 is set to surround the rod-shaped structure and is clamped in the guiding groove. In this example, the anti-detaching part 622 is set as an annular structure.

[0137] Please refer to Figure 11, which is a schematic perspective view of the scraping device provided in the embodiment of the present application. As shown in the figure, the scraping device 5 includes a main body 51, and a plurality of first through holes 515 are provided on the main body 51. The first through holes 515 are used in cooperation with the above-mentioned second connecting member 242. The guiding groove 514 in this example is shown in green in the figure. In this example, the guiding groove is provided to protrude from the surface of the main body, or the guiding groove can also be provided to be recessed in the surface of the main body. Among them, the anti-detachment portion 622 of the handle is clamped in the guiding groove, and the holding portion 61 of the handle is located above the guiding groove. In this example, the guiding groove 514 is a groove-shaped structure including two tracks provided on the upper surface of the main body 51.

[0138] Please refer to Figure 12 , which is Figure 11 a schematic perspective view of the scraping device shown in another perspective. As shown in the figure, the main body 51 includes a base 512, and a wiping surface (not shown) is detachably mounted on the base 512. The main body 51 and its base 512 form an accommodating space (not shown), and a part of the scraping mechanism 1 is accommodated in this accommodating space. The base 512 includes an opening 513. When the end of the driving assembly 3 protrudes from the opening 513 so that the scraping device moves, there is a large frictional force between the driving assembly 3 and the surface to be scraped.

[0139] Please refer to Figure 13, is an exploded view of the scraping device provided in the embodiments of the present application. As shown in the figure, the scraping device 5 includes a guiding groove 514 provided on the upper surface of the main body 51 and a movable handle 6 that can slide in the guiding groove 514. In this example, the guiding groove 514 is provided to include two tracks parallel to two sides of a triangle. The handle 6 includes a hand-held portion 61 and a connecting portion 62. The first end of the connecting portion 62 is threadedly connected to the hand-held portion 61, and the second end of the connecting portion 62 is snap-fitted in the guiding groove 514. The main body 51 further includes a base 512. A wiping surface (not shown) is provided on one side of the base 512 facing the surface to be scraped. A wiping cloth is mounted on the wiping surface for scrubbing the glass surface. An opening 513 is provided in the middle of the base 512, and the end of the driving assembly 3 protrudes from the opening 513. In this example, the main body 51 and its base 512 form an accommodating space, and part of the driving assembly 3 and the scraping assembly 2 are accommodated in this accommodating space. The driving assembly 3 includes a first transmission unit 311, a friction unit 312, and a connecting rod 32 (only one connecting rod is shown in the figure). A spring (not shown) is provided between the friction unit 312 and the first transmission unit 311. One end of the friction unit 312 passes through the opening 513 for abutting against the surface to be scraped. The connecting rod 32 connects the first transmission unit 311 and the third transmission unit 25. The scraping assembly 2 includes a third transmission unit 25 and a squeegee unit 24. The third transmission unit 25 is mounted in the main body 51 and abuts against one side of the squeegee unit 24. A squeegee is mounted on one side of the squeegee unit 24 for scraping water stains on the glass. A second connecting member 242 provided on the other side of the squeegee unit 24 is movably connected to a through hole 515 on the main body 51 through a spring (not shown).

[0140] When the user uses the scraping device 5, the user slides the handle 6 to the vertex (H shown in the figure) position of the guiding groove 514, and holds the handle 6 to place the scraping device on the surface to be scraped (such as glass). At this time, the friction unit 312 abuts against the surface to be scraped. Then the user presses the scraping device 5 downward against the surface to be scraped and applies a force at the vertex H to push the scraping device to work in the forward direction. During the movement of the scraping device, the scraping assembly (shown as JK in the figure) at the opposite direction of the vertex H extends out of the wiping surface to perform the scraping work. When the user needs to switch the direction, the force that promotes the forward movement of the scraping device at the vertex H is removed. At this time, the scraping assembly JK retracts from the wiping surface. Then the user slides the handle 6 from the vertex H to another vertex position of the guiding groove 514 and continues to apply a force at this vertex to push the scraping device to work in the forward direction. During the movement of the scraping device, the scraping assembly at the opposite direction of this vertex extends out of the wiping surface to perform the scraping work.

[0141] In the scraping device of the present application, during the use process, the switching of the scraping assembly is realized by switching the force application point of the handle in the guiding groove, so as to realize the switching of multiple directions without changing the scraping device itself, which is convenient for the user to operate flexibly and improves the user experience.

[0142] The present application further provides a scraping assembly, including a first scraping device and a second scraping device, at least one of the first scraping device and the second scraping device being the scraping device described above Figures 11 to 13 wherein the first scraping device and the second scraping device are attracted to each other by magnetic force. As Figure 13 shown, a magnet mounting area 516 is provided on the base 512 of the scraping device 5, and the magnet assembly is mounted in this area. When wiping and cleaning the inner and outer surfaces of the glass simultaneously, for example, wiping a window glass, since the magnet assembly is mounted in the magnet mounting areas 516 of the first scraping device and the second scraping device, the first scraping device and the second scraping device are magnetically attracted to each other through the magnet assembly, thereby clamping the glass. In use, the first scraping device and the second scraping device are respectively located on the inner surface and the outer surface of the object to be scraped (such as glass) to clean the object to be wiped. Since the first scraping device and the second scraping device are attracted to each other by means of magnets, etc., when the user drives the first scraping device to slide along the surface of the object to be wiped to wipe the object to be wiped, the second scraping device is driven by the movement of the first scraping device, so that the second scraping device also slides along the surface of the object to be wiped, thereby realizing scraping of water stains and the like on the inner surface and the outer surface of the object to be wiped.

[0143] It should be noted that the positions and numbers of the above-mentioned magnet mounting areas are only examples, and those skilled in the art can make corresponding adjustments to the magnet mounting areas according to the shape of the scraping device, the thickness of the object to be scraped, etc., which will not be elaborated here.

[0144] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present application.
