For the specific arrangement of the driving assembly, reference may be made to the descriptions of patent application numbers 202010670650.2, 202021375474.1 and the like previously filed by the applicant, and the description thereof is omitted.
In the embodiment of the present application, the posture adjustment assembly 20 is in transmission connection with the scraper 10, so as to adjust the posture of the scraper 10, and the present application does not limit the specific composition of the posture adjustment assembly 20 and the form how to adjust the posture of the scraper 10.
Alternatively, the attitude of the scraper 10 may be adjusted by the user's manual force via the attitude adjustment assembly 20.
Alternatively, the attitude of the wiper 10 may be adjusted by an electrically powered device (e.g., a motor) via the attitude adjustment assembly 20.
Alternatively, the attitude adjustment assembly 20 may adjust the attitude of the wiper 10 by swinging the wiper 10.
In the embodiment of the present application, when the scraping and cleaning device performs the reciprocating movement to scrape the surface to be cleaned, the first direction a1 of the scraping member 10 relative to the moving direction is always in the inclined scraping position, which means that the scraping and cleaning device performs the reciprocating movement while the relative moving direction is always in the inclined scraping position.
For example, when the scraping cleaning apparatus is moved in the first direction a1 to scrape a surface to be cleaned, the posture adjustment assembly 20 adjusts the posture of the scraping member 10 so that the scraping member 10 is in an inclined scraping position with respect to the moving direction. When the scraping and cleaning device moves in the direction a2 to scrape the surface to be cleaned, the posture adjustment assembly 20 adjusts the posture of the scraping member 10 again so that the scraping member 10 is in the horizontal scraping position.
Here, the inclined wiping position is a relative position with respect to the moving direction of the wiping cleaning apparatus, and is an angular position at which the wiping member 10 is in an inclined state with respect to the moving direction, and the wiping member 10 is neither perpendicular nor parallel to the moving direction; instead, the horizontal wiping position is arranged horizontally with respect to the inclined wiping position, and the length direction of the wiping member 10 (i.e., the extending direction of the wiping member 10) is substantially perpendicular to the moving direction.
It is worth mentioning that the inclined scraping position may not be a fixed position (angle), for example, the inclined scraping position may be changed (i.e. the scraping member 10 may swing) during the movement of the scraping cleaning apparatus, as long as it is satisfied that the scraping member 10 is always inclined with respect to the moving direction and that the first end 11 is always located at the front side of the moving direction with respect to the second end 12. The wiper element 10 can also push the water spots together towards the same side.
As shown in fig. 1a, when the scraping and cleaning device moves in the first direction a1, the attitude adjustment assembly 20 controls the included angle between the first end 11 and the moving direction to be α 1, and during the moving process, the scraping element 10 can swing to a certain extent, so that the included angle α 1 can be changed, for example, α 1 can be changed between 5 degrees and 60 degrees. It will be readily appreciated that even if the scraper member 10 were to undergo a certain degree of rocking, the scraper member 10 will always urge water spots to the right, since the first end 11 is always located forward of the second end 12.
Similarly, as shown in fig. 1b, when the scraping and cleaning device moves in the second direction a2, the posture adjustment assembly 20 controls the length direction of the scraping element 10 to be substantially perpendicular to the moving direction, and during the moving process, the scraping element 10 can also swing to a certain extent, that is, the length direction of the scraping element 10 is kept substantially perpendicular to the moving direction.
Alternatively, when the scraping cleaning device moves to the first direction a1 to scrape the surface to be cleaned, the posture adjustment assembly 20 can also adjust and maintain the scraping member 10 at the inclined scraping position, and the posture adjustment assembly 20 controls the included angle α 1 between the first end 11 and the moving direction to be kept unchanged, namely, the included angle α 1 is a constant value. When the scraping cleaning device moves to the second direction a2 to scrape the surface to be cleaned, the posture adjustment assembly 20 can adjust and maintain the scraping member 10 at the horizontal scraping position, and the posture adjustment assembly 20 controls the length direction of the scraping member 10 to be kept approximately perpendicular to the second direction a 2.
Optionally, in order to guarantee the effect of assembling to the water stain, and then prevent that the water stain flows to the left side of scraping piece 10, when scraping piece 10 is in the slope scraping position, the value range of contained angle alpha 1 between first end 11 and the moving direction is: alpha 1 is more than or equal to 5 degrees and less than or equal to 60 degrees. For example, α 1 may be 15 °, 30 °, 45 °, 55 °, and the like.
When the scraper 10 is in the horizontal scraping position, the scraper 10 remains substantially perpendicular to the second direction a 2.
The scraping and cleaning device provided by the embodiment of the application is further described in detail with reference to the attached drawings.
For convenience of description and understanding, the scraping cleaning device provided in the present application will be further described in the following description with a glass surface as the surface to be cleaned, that is, the scraping cleaning device in the following may be understood as a glass wiper. On this basis, hereinafter the first direction a1 may be understood as being up (upward) and the second direction a2 as being down (downward), and vice versa.
Fig. 2 is a schematic structural diagram of an example of the scraping and cleaning device according to the embodiment of the present application in an operating state. Fig. 2(a) is a schematic view showing a state in which the scraping and cleaning device moves in the first direction a 1. Fig. 2(b) is a schematic view of the state in which the scraping and cleaning device moves in the second direction a 2.
As shown in fig. 2, in the present embodiment, the posture adjustment assembly 20 is configured to drive the body 30 to deflect so as to drive the scraping element 10 to deflect, so that the scraping element 10 is located at an inclined scraping position or a horizontal scraping position relative to the moving direction. Optionally, the scraper 10 may be fixed to the body 30 at this time.
Further, the scraping cleaning device further comprises a push-pull rod 40, and the push-pull rod 40 is connected with the body 30 through the attitude adjusting assembly 20. At this time, the posture adjustment assembly 20 can be used to transmit the power of the push-pull rod 40 on the one hand so that the wiping and cleaning device can be moved, and can also adjust and maintain the wiper member 10 in the inclined wiping position or the horizontal wiping position on the other hand.
For example, the user can hold the push-pull rod 40 with his hand, and push the body 30 upward through the push-pull rod 40 and the attitude adjustment assembly 20, thereby scraping and cleaning the glass surface upward, while the attitude adjustment assembly 20 keeps the scraping member 10 in an inclined scraping position, and the water stains being scraped are gathered to the right.
When the scraping cleaning device is moved to the top dead center position, the user can move the body 30 to the right side to a certain extent, then the user pulls the body 30 downwards through the push-pull rod 40 and the posture adjusting assembly 20, and then scrapes and cleans the glass surface downwards, at the moment, the posture adjusting assembly 20 keeps the scraping piece 10 at the horizontal scraping position, and the scraped water stain is driven by the scraping piece 10 to be gathered to the bottom of the glass window. Until the scraping and cleaning device is moved to the bottom dead center position, the user displaces the body 30 to the right again to a certain extent, and then continues to push the body 30 upwards through the push-pull rod 40, so as to realize the reciprocating movement of the body 30 on the glass surface, and further realize the continuous cleaning of the glass surface.
Alternatively, to improve the practicability, the push-pull rod 40 may be a telescopic rod, and a handle convenient for a user to hold may be further provided at an end of the push-pull rod 40.
The attitude adjustment assembly 20 provided in the embodiment of the present application will be further described with reference to fig. 2.
As shown in fig. 2, the attitude adjustment assembly 20 provided in the embodiment of the present application includes a fixed member 21, an oscillating member 22, and a limiting member 23.
Wherein, the fixed member 21 is fixedly connected with the push-pull rod 40, and the swinging member 22 is connected with the body 30.
Alternatively, the fixing member 21 and the push-pull rod 40 may be integrally formed by injection molding or the like.
Optionally, the oscillating member 22 is fixedly connected or hinged with the body 30.
For example, the oscillating member 22 can be hinged to opposite sides of the body 30 by means of connecting arms 22a of U-shape. At this time, hinge holes may be formed at opposite sides of the body 30, respectively, and hinge shafts are fixed to side walls of the link arms 22a facing the local body 30, the hinge shafts being rotatably coupled in the hinge holes.
Further, the swinging member 22 is hinged on the fixed member 21, the swinging member 22 can swing relative to the fixed member 21, and the swinging member 22 swings to drive the body 30 to deflect, so as to drive the scraping member 10 to deflect.
In the embodiment of the present application, the fixed member 21 and the swinging member 22 are both plate-shaped structures and are hinged to each other by a rotating shaft 25.
Alternatively, the rotation shaft 25 may be any one of a pin, a rivet, a screw, a bolt, and the like.
Fig. 3 is a side view of the fixing member 21 provided in the embodiment of the present application. As shown in fig. 3, the fixing member 21 is integrally U-shaped, and the swinging member 22 is hinged in the cavity of the U-shaped structure. At this time, the fixing member 21 includes three parts, that is, a bottom plate 21a and two side plates 21b connected to both sides of the bottom plate 21a, and the swinging member 22 may be clamped between the two side plates 21b, thereby being capable of performing a better limit function on the swinging member 22.
At this time, the rotating shaft 25 may pass through the two side plates 21b and the swinging member 22, so that the swinging member 22 is hinged in a cavity of the U-shaped structure, in which the swinging member 22 can swing.
The stopper 23 is used to restrict the swing of the swing member 22 so that the swing member 22 can swing between two limit positions. When the oscillating piece 22 is oscillated to one limit position, the oscillating piece 22 drives the scraping piece 10 through the body 30 to be adjusted to the inclined scraping position, and when the oscillating piece 22 is oscillated to the other limit position, the oscillating piece 22 drives the scraping piece 10 through the body 30 to be adjusted to the horizontal scraping position.
The specific structure of the stopper 23 is not limited in the present application, as long as the swing of the swing member 22 can be restricted.
As shown in fig. 2, in the embodiment of the present application, the limiting member 23 includes an arc-shaped sliding chute 23a and a sliding pin 23b, which are used in cooperation with each other. The arc-shaped sliding groove 23a is opened on the swinging member 22, the sliding pin 23b is correspondingly arranged on the side surface of the fixing member 21 facing the swinging member 22, the rear end part of the sliding pin 23b is fixedly connected with the fixing member 21, and the front end part is arranged in the arc-shaped sliding groove 23a in a sliding manner.
One end of the arc chute 23a is a first limit end (i.e., the upper end of the arc chute 23a in fig. 2), and when the swinging member 22 is swung and the slide pin 23b abuts against the first limit end, the scraping member 10 is adjusted to the inclined scraping position. The other end of the arc chute 23a is a second limit end (i.e., the lower end of the arc chute 23a in fig. 2), and when the swinging member 23 is swung and the slide pin 23b abuts against the second limit end, the scraping member 10 is adjusted to the horizontal scraping position.
In the present embodiment, the scraper 10 can be adjusted and held in the inclined or horizontal scraping position by the friction between the scraping cleaning device and the glass surface.
The oscillating member 22 is held on the fixed member 21 by the stopper member 23 under the action of the frictional force between the scraping cleaning device and the glass surface, so that the scraping member 10 is held in the inclined scraping position or the horizontal scraping position.
Specifically, as shown in fig. 2a, when the user pushes the body 30 to move upward on the glass surface by means of the push-pull rod 40, a frictional force is generated between the body 30 and the glass surface. More specifically, at this time, the body 30 is subjected to a downward friction force, under the action of the friction force, the swinging member 22 swings downward relative to the fixing member 21, so that the first limit end of the arc-shaped sliding groove 23a and the sliding pin 23b abut against each other, the swinging member 22 is held on the fixing member 21 through the limit member 23, the swinging member 22 holds the scraping member 10 at an inclined scraping position through the body 30, and the scraped water stains are gathered to the right side.
As shown in fig. 2b, when the body 30 moves upward on the glass surface to the top dead center position, the user stops pushing the body 30 and pulls the body 30 downward through the push-pull rod 40, thereby changing the moving direction of the body 30. At this time, when the user pulls the body 30 to move downwards on the glass surface through the push-pull rod 40, a friction force is generated between the body 30 and the glass surface, and more specifically, the body 30 is subjected to an upward friction force, under the action of the friction force, the swinging member 22 swings upwards relative to the fixing member 21, so that the second limit end of the arc-shaped chute 23a and the sliding pin 23b abut against each other, the swinging member 22 is held on the fixing member 21 through the limit member 23, the swinging member 22 holds the scraping member 10 in a horizontal scraping position through the body 30, in which the length direction of the scraping member 10 is substantially perpendicular to the vertical downward direction, and further, the scraped water stains are driven to flow and converge vertically downward.
That is, when the moving direction of the scraping cleaning device is switched between the up-down direction, the oscillating member 22 can be deflected by the frictional force between the scraping cleaning device and the glass surface, and further the scraping member 10 is held in the inclined scraping position or the horizontal scraping position.
Alternatively, in other embodiments, the positions of the arc chute 23a and the slide pin 23b may be reversed. At this time, the arc chute 23a may be opened on the fixed member 21, the slide pin 23b is correspondingly disposed on the side surface of the swinging member 22, the rear end portion of the slide pin 23b is fixedly connected to the swinging member 22, and the front end portion is slidably disposed in the arc chute 23 a. Through the above arrangement, similar technical effects can be generated, and the description of the application is omitted.
Fig. 4 is a schematic structural diagram of another example of the scraping and cleaning device according to the embodiment of the present application in an operating state. Fig. 4(a) is a schematic view showing a state where the scraping and cleaning device moves in the first direction a 1. Fig. 4(b) is a schematic view of the state in which the scraping and cleaning device moves in the second direction a 2.
In view of the fact that the friction between the scraping and cleaning device and the surface to be cleaned may be relatively small and insufficient to deflect the swinging member 22, in contrast to the aforementioned embodiment shown in fig. 2, in the present embodiment, the posture adjustment assembly 20 further includes a power member 24, and the swinging member 22 is deflected by the power member 24 when the moving direction of the scraping and cleaning device is switched between the first direction a1 and the second direction a 2.
The power member 24 is capable of driving the oscillating member 22 to oscillate between two extreme positions, which in turn enables the scraper 10 to switch between an inclined scraping position and a horizontal scraping position. The specific structure of the power member 24 and how to drive the swinging member 22 to swing are not limited in this application, as long as the above-mentioned functions can be achieved.
As shown in fig. 4, in the present embodiment, the power member 24 includes a jack 24 a; the ejector pin 24a is used to push the oscillating member 22 to oscillate.
Further, the power member 24 also includes a push-pull handle 24 c. The push-pull handle 24c penetrates through the push-pull rod 40 and is fixedly connected with the push-pull rod 24a, a sliding groove is formed in the push-pull rod 40, the push-pull handle 24c can move back and forth in the sliding groove, a user can drive the push-pull rod 24a to move upwards by pushing the push-pull handle 24c, and then the swinging piece 22 is pushed, so that the swinging piece 22 can swing upwards.
Further, the power member 24 further includes a return spring 24b, and the return spring 24b is also disposed inside the push-pull rod 40 and sleeved on the outer periphery of the top rod 24 a. When the force applied to the jack 24a by the user disappears, the jack 24a can be reset by providing the return spring 24 b.
In the present embodiment, the stopper 23 is a stopper 23c, and the stopper 23c is used to limit one limit position of the swinging member 22 to define the scraper 10 at the inclined scraping position.
Optionally, in order to improve the degree of automation and further improve the user experience, an electric device such as a motor may be further provided to drive the push rod 24a to push the oscillating member 22, and at this time, a corresponding control button may be provided on the outer wall surface of the push-pull rod 40 to control the operation of the electric device.
As shown in fig. 4, a stopper 23c may be fixedly provided on an inner side wall of the side plate 21b of the fixed member 21, and the stopper 23c may abut against the swinging member 22 to limit the swinging member 22.
As shown in fig. 4, in the present embodiment, the stopper 23c may be provided on the inner wall surface of the bottom plate 21 a.
Fig. 5 is a schematic structural diagram of a further example of the scraping and cleaning device according to the embodiment of the present application in an operating state. Fig. 5(a) is a schematic view showing a state where the scraping and cleaning device moves in the first direction a 1. Fig. 5(b) is a schematic view of the state in which the scraping and cleaning device moves in the second direction a 2.
In contrast to the embodiment shown in fig. 2 and 4, in the present embodiment, the fixed member 21 is provided with a first gear structure 26a, the swinging member 22 is provided with a second gear structure 26b, and the first gear structure 26a and the second gear structure 26b are engaged with each other. By providing the first gear structure 26a and the second gear structure 26b which mesh with each other, the swinging of the swinging member 22 can be controlled more smoothly.
As shown in fig. 5, the first gear structure 26a may be rotatably connected to an inner sidewall of the side plate 21b, and the second gear structure 26b may be formed on a sidewall of the swinging member 22, and the first gear structure 26a may be engaged with the second gear structure 26b as a supporting gear.
Alternatively, the swinging member 22 may be formed in a hollowed-out structure, so that the weight of the swinging member 22 can be reduced to facilitate swinging.
In the present embodiment, the stopper 23 is a stopper 23c for holding the oscillating member 22 at the inclined scraping position, and the inclination angle of the oscillating member 22 can be regulated by adjusting the position of the stopper 23c and the shape of the oscillating member 22.
As shown in fig. 5a, when the user pushes the body 30 to move upward on the glass surface by means of the push-pull rod 40, a downward frictional force is generated between the scraping cleaning device and the glass surface. That is, at this time, the body 30 receives a downward friction force, and under this friction force, the oscillating member 22 oscillates downward relative to the fixed member 21, so that the oscillating member 22 and the stopper 23c abut against each other, the oscillating member 22 is held on the fixed member 21 by the stopper 23c, the oscillating member 22 holds the wiper member 10 at the inclined wiping position by the body 30, and the wiped water stains are collected to the right side.
As shown in fig. 5b, when the body 30 moves upward on the glass surface to the top dead center position, the user stops pushing the body 30 and pulls the body 30 downward through the push-pull rod 40, thereby changing the moving direction of the body 30. At this time, when the user pulls the body 30 to move down on the glass surface by the push-pull rod 40, an upward frictional force is generated between the scraping cleaning device and the glass surface. That is, at this time, the body 30 is subjected to an upward friction force, under the action of the friction force, the oscillating member 22 oscillates upward relative to the fixed member 21, the oscillating member 22 drives the body 30, so that the length direction of the scraping member 10 reaches a position substantially perpendicular to the downward direction, and under the continuous pulling action of the push-pull rod 40, the scraping member 10 is always kept at the horizontal scraping position, so that the scraped water stains are gathered to the lower portion of the glass window.
During the swinging process of the swinging member 22, the first gear structure 26a rotates relative to the fixed member 21 and is meshed with the second gear structure 26b, so that the swinging of the swinging member 22 can be more smoothly and controllably swung.
Fig. 6 is a schematic structural diagram of a further example of the scraping and cleaning device according to the embodiment of the present application in an operating state. Fig. 6(a) is a schematic view showing a state where the scraping and cleaning device moves in the first direction a 1. Fig. 6(b) is a schematic view of the state in which the scraping and cleaning device moves in the second direction a 2.
In contrast to the previously described embodiments shown in fig. 2, 4 and 5, in the present exemplary embodiment the fixed part 21 and the pivoting part 22 are articulated to one another via a rocker 27.
Specifically, one end of the swing link 27 is rotatably connected to the fixed member 21 through a rotating shaft, and the other end of the swing link 27 is rotatably connected to the swinging member 22 through a rotating shaft, so that the fixed member 21 and the swinging member 22 are hinged to each other.
At this time, the stopper 23c may be fixedly provided at one side of the swing lever 27 to thereby restrict the scraping member 10 to the inclined scraping position by defining the swing member 22.
Optionally, in this application embodiment, the number of the swing rods 27 is two, and in other embodiments, the number of the swing rods 27 may also be one, three, or more, which is not limited in this application.
Fig. 7 is a schematic structural diagram of another example of the scraping and cleaning device according to the embodiment of the present application. Fig. 8 is a schematic view of the structure of the body 30 in the scraping cleaning device shown in fig. 7.
As shown in fig. 7 and 8, in the present embodiment, the attitude adjustment assembly 20 includes a U-shaped bracket 28 fixedly connected to a push-pull rod 40. One end of the U-shaped bracket 28 is hinged in a through hole of a side wall of the body 30 by a first rotation pin, relative to which the body 30 can oscillate. The other end of the U-shaped bracket 28 is slidably disposed in a strip-shaped sliding slot 33 of the other side wall of the body 30 through a second rotating pin 29.
When the user pushes the body 30 to move upwards on the glass surface through the push-pull rod 40, the body 30 is subjected to downward friction, under the action of the friction, the right end of the body 30 swings downwards relative to the left end, so that the limiting end part of the front side of the strip-shaped sliding chute 33 in the moving direction (namely the end part of the upper side of the strip-shaped sliding chute 33 in fig. 8) is abutted against the second rotating pin 29, at the moment, the body 30 keeps the scraping piece 10 at an inclined scraping position, and the scraped water stains are gathered towards the right side.
When the body 30 moves upward on the glass surface to the top dead center position, the user stops pushing the body 30 and pulls the body 30 downward through the push-pull rod 40, thereby changing the moving direction of the body 30. At this time, when the user pulls the body 30 to move downward on the glass surface through the push-pull rod 40, the body 30 receives an upward friction force, and under the action of the friction force, the right end of the body 30 swings upward relative to the left end, so that the limiting end of the bar-shaped sliding chute 33 on the front side in the moving direction (i.e., the end of the lower side of the bar-shaped sliding chute 33 in fig. 8) abuts against the second rotating pin 29, and at this time, the body 30 keeps the scraping piece 10 at the horizontal scraping position, and the scraped water stains are gathered toward the lower portion of the glass window.
As shown in fig. 7 and 8, a magnetic adjusting knob 31 is further provided on the top cover of the main body 30, and the magnetic strength of the scraping and cleaning device can be changed by rotating the magnetic adjusting knob 31.
As shown in fig. 8, in the present embodiment, the scraping member 10 includes two members respectively disposed at opposite sides of the body 30.
Further, the two scrapers 10 are fixedly arranged and are not switched. However, it is preferred that the two scrapers 10 are switched. Specifically, the method comprises the following steps: a driving assembly may be further provided in the body 30, which drives the scraping member 10 located at the front side in the moving direction to be out of operation away from the glass surface and drives the scraping member 10 located at the rear side in the moving direction to be close to the glass surface for the scraping work, when the scraping cleaning apparatus performs the reciprocating movement to scrape the glass surface.
In order to achieve better cleaning effect, the middle of the attaching surface of the body 30 of the scraping cleaning device and the glass surface is generally provided with a wiper, and through the arrangement, the scraping cleaning device can be guaranteed to scrape and clean the surface to be cleaned according to the direction of the wiper in front and the scraping piece 10 behind, so that the technical effect of scraping before can be achieved, and the cleaning efficiency of the scraping cleaning device can be improved.
For example, when the scraping cleaning apparatus is moved upward in fig. 7 to scrape the glass surface, the driving assembly drives the scraping member 10 located upward in fig. 7 away from the glass surface to be inoperative, and drives the scraping member 10 located downward in fig. 7 close to the glass surface to perform the scraping work.
As another example, when the scraping cleaning apparatus is moved downward in fig. 7 to scrape the glass surface, the driving unit drives the scraping member 10 located downward in fig. 7 to be out of operation away from the glass surface, and drives the scraping member 10 located upward in fig. 7 to be close to the glass surface to perform the scraping work.
The specific arrangement of the driving assembly can be found in patent application nos. 202010670650.2, 202021375474.1, etc. previously filed by the applicant, and will not be described herein.
On the other hand, the embodiment of the application also provides a scraping and cleaning assembly. The scraping and cleaning assembly comprises a first scraping and cleaning device and a second scraping and cleaning device which are mutually attracted by magnetic force, and the first scraping and cleaning device can be the scraping and cleaning device provided by any one of the previous embodiments.
Since the scraping and cleaning assembly adopts the scraping and cleaning device provided by the foregoing embodiment, the scraping and cleaning assembly also has the technical effects corresponding to those of the scraping and cleaning device, and the details are not repeated herein.
The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
