Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning appliances, in particular to an adaptive window wiper. Background Art

[0002] Ordinary window wipers on the market usually have a scraper and a mounting base fixedly connected. When cleaning surfaces at different heights, the operator needs to constantly change the angle of the gripping rod so that the scraper can keep contact with the surface to be cleaned, especially at a suitable angle, making cleaning more labor-saving and convenient.

[0003] Chinese patent CN218500611U discloses "An Angle-Adaptive Window Wiper," in which a mounting plate is detachably connected to a gripping rod via an elastic connector. The elastic connector allows the wiper to swing up and down relative to the gripping rod as the mounting plate rotates, allowing the soft wiper and lower scraper to better adhere to the glass or countertop for wiping. However, in actual use, when the angle between the gripping rod and the surface to be cleaned changes, the pressure between the scraper and the surface to be cleaned varies significantly. To avoid excessive contact pressure between the scraper and the surface to be cleaned, which could cause severe deformation of the scraper, the operator needs to adjust the external force applied by the operator at any time, which is relatively inconvenient. Excessive contact pressure between the scraper and the surface to be cleaned may also increase the contact area between the scraper and the surface to be cleaned, resulting in poor scraping effect on water stains and the like. Utility Model Content

DETAILED DESCRIPTION

[0064] In order to enable those skilled in the art to better understand the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0065] An adaptive window wiper includes a gripping rod 1 and a scraping strip 2. The scraping strip 2 is made of a soft, deformable material such as silicone and having a certain supporting hardness. A mounting seat 3 is provided between the gripping rod 1 and the scraping strip 2. The scraping strip 2 is connected to the mounting seat 3. At least a portion of the mounting seat 3 is floatingly arranged. When the scraping strip 2 contacts the surface 7 to be cleaned, at least a portion of the mounting seat 3 can float. Therefore, when the angle between the gripping rod 1 and the surface 7 to be cleaned changes, the scraping strip 2 remains against the surface 7 to be cleaned, and the two are against each other at a suitable angle and with suitable acting pressure.

[0066] When the adaptive window wiper is in use, the scraper 2 is used to scrape liquid or impurities off the surface of the surface to be cleaned 7. Since the surface of the surface to be cleaned 7 is not necessarily smooth and may have a curved surface structure, a corner surface, or multiple consecutive curved surface structures, or multiple consecutive corner surface structures, the user needs to change the angle between the gripping rod 1 and the surface to be cleaned 7 to avoid inappropriate pressure between the end of the scraper 2 and the surface to be cleaned 7, and to avoid excessive or insufficient contact area between the scraper 2 and the surface to be cleaned 7, which in turn leads to poor cleaning effect. However, when the user changes the angle between the gripping rod 1 and the surface to be cleaned 7, the pressure between the scraper 2 and the surface to be cleaned 7 may change too much due to excessive angle change, which has an adverse effect on the scraping effect and ease of operation of water stains.

[0067] The present invention utilizes at least a partial floating setting of the mounting seat 3, so that when encountering the curved convex part of the surface to be cleaned 7, the floating part of the mounting seat 3 floats in the direction away from the surface to be cleaned 7, causing the scraper 2 to move inward, so that even if the user applies a constant operating force on the window wiper, it can ensure that the end 21 of the scraper 2 and the surface to be cleaned 7 are against each other with appropriate acting pressure, that is, having appropriate wiping pressure; when moving from the curved convex part of the surface to be cleaned 7 to the curved concave part, the floating part of the mounting seat 3 automatically floats in the direction close to the surface to be cleaned 7, causing the scraper 2 to automatically move outward, ensuring that the end 21 of the scraper 2 extends out and is against the surface to be cleaned 7 with appropriate acting pressure, that is, having appropriate wiping pressure; all of the above do not require a large change in the angle between the gripping rod 1 and the surface to be cleaned 7, so the operation is more convenient, the wiping pressure remains relatively stable, and the cleaning effect is better.

[0068] When the window wiper needs to clean the surface to be cleaned 7 at different heights, usually at a higher height, the user will adjust the angle between the gripping rod 1 and the surface to be cleaned 7 to be smaller, and usually at a lower height, the user will adjust the angle between the gripping rod 1 and the surface to be cleaned 7 to be larger. Once the angle between the gripping rod 1 and the surface to be cleaned 7 changes too much, the pressure acting between the scraper 2 and the surface to be cleaned 7 will change significantly. By utilizing at least a partial floating setting of the mounting base 3, it is possible to ensure that the scraper 2 and the surface to be cleaned 7 are in contact with each other when the above-mentioned angle changes, and that they are in contact with each other at an appropriate pressure and an appropriate angle. At this time, the user does not need to adjust the operating force in a timely manner, and the scraper 2 can also make adaptive adjustments. The pressure acting between the scraper 2 and the surface to be cleaned 7 is more stable, and the wiping pressure is relatively stable, ultimately ensuring a better cleaning effect. It should be noted that the angle between the gripping rod 1 and the surface to be cleaned 7 and the angle between the scraper 2 and the surface to be cleaned 7 are not the same.

[0069] In addition, during the processing, the end surface of the scraper 2 is not necessarily completely horizontal. The middle part may bulge outward, or it may be concave inward, or it may form a curved wavy structure on the end surface. Furthermore, due to the different materials of the scraper 2 itself, the specific circumstances of its deformation under stress are different. If the contact pressure between the scraper 2 and the surface to be cleaned 7 is too large, the contact area between the two is too large, resulting in excessive resistance to scraping water stains and other impurities; if the contact pressure between the scraper 2 and the surface to be cleaned 7 is too small, the contact area between the two is too small, resulting in a small range of water stains and other impurities to be scraped off in a single time, and the wiping pressure is also too small. By using the at least partial floating setting of the mounting seat 3, the user does not need to change the operating force in real time. The scraper 2 can also automatically adjust the contact force with the surface to be cleaned 7 to ensure that the cleaning operation is performed with appropriate pressure and contact area, that is, the appropriate wiping pressure is always maintained. The floating part of the mounting seat 3 can be a structure in the prior art and is not specifically limited. Specifically, in this embodiment, an elastic member 4 is disposed within the mounting base 3. This elastic member 4 allows the mounting base 3 to float. Thus, when the scraping strip 2 abuts the surface to be cleaned 7, the elastic member 4 can deform, causing the end 21 of the scraping strip 2 to abut against the surface to be cleaned 7. The specific mounting position of the elastic member 4 is not limited herein. It should be noted that the elastic member 4 being deformable herein refers to the ability to further deform based on its existing deformation, not to the elastic member 4 being deformed only at this point.

[0070] Mounting base 3 is provided with both scraper strip 2 and wiper 5. Wiper 5 is oriented in the same direction as, or tends to be oriented in the same direction as, scraper strip 2. In other words, wiper 5 and scraper strip 2 are located on the same side of mounting base 3. At least a portion of mounting base 3 is capable of floating, so that when the angle between gripping rod 1 and surface 7 to be cleaned changes, scraper strip 2 maintains contact with surface 7 at an appropriate angle and with appropriate pressure. Simultaneously, wiper 5 also maintains contact with surface 7. Of course, in other embodiments, only scraper strip 2 may be provided without wiper 5.

[0071] The scraper strip 2 and the surface to be cleaned 7 are at a suitable angle, specifically, the angle between the side surface of the end 21 of the scraper strip 2 and the surface to be cleaned 7 is 20-85 degrees, that is, Figure 21 More specifically, the end 21 of the scraper strip 2 has a first edge 211 and a second edge 212 , and the angle α is the angle between the side where the second edge 212 is located and the surface 7 to be cleaned. Figure 21 The state in which the second edge 212 abuts against the surface to be cleaned 7 in the shown state is the best state. Normally, the second edge 212 and a portion of the side surface thereof abut against the surface to be cleaned 7 .

[0072] Of course, the scraper strip 2 in the prior art may also have only one edge. In this case, when the scraper strip 2 swings relative to the surface 7 to be cleaned, it is this edge that abuts against the surface 7 to be cleaned; the scraper strip 2 in the prior art may also have the first edge 211 and the second edge 212 not being in the same horizontal plane. In this case, when the scraper strip 2 swings relative to the surface 7 to be cleaned, whether it swings upward or downward, it is the first edge 211 or the second edge 212 that abuts against the surface 7 to be cleaned.

[0073] The scraper bar 2 and the surface to be cleaned 7 are offset with appropriate pressure. Specifically, the torsion and pressure of the scraper bar 2 can effectively remove water stains, while the side of the scraper bar 2 will not have too large a contact area and contact pressure with the surface to be cleaned 7.

[0074] Specifically, the floating portion of the mounting base 3 can be connected to the scraper 2, so that the scraper 2 and the mounting base 3 float relative to each other; or, the floating portion of the mounting base 3 can be connected to the wiper 5, so that the wiper 5 and the mounting base 3 float relative to each other; or, the floating portion of the mounting base 3 can be connected to both the scraper 2 and the wiper 5, so that the scraper 2 and the mounting base 3 float relative to each other, and at the same time, the wiper 5 and the mounting base 3 also float relative to each other. It should be noted that Figure 9 Taking the direction shown as an example, the scraper 2 and the mounting seat 3 float relative to each other, which means that the scraper 2 can move in the up and down directions, left and right directions relative to the mounting seat 3, or can swing up and down, or include up and down, left and right movement and swinging at the same time, and its movement direction is not specifically limited to a certain direction.

[0075] When the adaptive window wiper is in use, the scraper 2 is used to scrape off the liquid or impurities on the surface of the surface to be cleaned 7, and the wiper 5 is used to absorb the liquid or impurities collected by the scraper 2. Figure 22 In the case of the above situation, that is, the angle between the gripping rod 1 and the surface to be cleaned 7 is too small, the wiping material 5 contacts the surface to be cleaned 7, and there is a certain distance between the scraping strip 2 and the surface to be cleaned 7 (the figure shows a larger distance for better explanation, and there is no such large distance in actual application). At this time, the scraping strip 2 cannot work effectively; it is also possible that Figure 23 In the above situation, the angle between the handle 1 and the surface to be cleaned 7 is too large, and the scraper 2 contacts the surface to be cleaned 7, or even the two collide with each other, causing the scraper 2 to deform. At the same time, there is still a certain distance between the wiping material 5 and the surface to be cleaned 7. In this case, the liquid collected by the scraper 2 cannot be quickly absorbed. Both of the above situations will have an adverse effect on the cleaning effect.

[0076] To avoid Figure 22 、 Figure 23In the above situation, the present invention utilizes at least a portion of the mounting base 3 to float. This includes the floating structure of the mounting base 3 causing the scraper 2 to float, the floating structure of the mounting base 3 causing the wiper 5 to float, and the floating structure of the mounting base 3 causing both the scraper 2 and the wiper 5 to float. Thus, when the angle between the gripping rod 1 and the surface to be cleaned 7 is too large, the scraper 2 can retract inward, allowing the wiper 5 to also adhere to the surface to be cleaned 7, ensuring that both the scraper 2 and the wiper 5 simultaneously abut against the surface to be cleaned 7. When the angle between the gripping rod 1 and the surface to be cleaned 7 decreases from large to small, the scraper 2 can extend outward, preventing the scraper 2 from separating from the surface to be cleaned 7. That is, when the angle between the holding rod 1 and the surface to be cleaned 7 changes, the scraper 2 and the wiper 5 both press against the surface to be cleaned 7; and because the floating structure of the mounting base 3 is provided, when the angle between the holding rod 1 and the surface to be cleaned 7 changes within a large range, the pressure between the scraper 2 and the surface to be cleaned 7 does not change too much, and the end 21 of the scraper 2 can press against the surface to be cleaned 7 at a suitable angle and with a suitable acting pressure, that is, there is always a suitable wiping pressure, and the contact area between the wiper 5 and the surface to be cleaned 7 is larger.

[0077] like Figures 1-4 As shown, the mounting base 3 includes a first base body 31, a second base body 32 and a third base body 33. The scraper strip 2 is arranged on the first base body 31. The first base body 31 and the scraper strip 2 are connected separately, or the scraper strip 2 is connected to the first base body 31 as a whole by a secondary injection molding process. The second base body 32 is connected to a wiper 5. Figure 2 The direction shown is taken as an example, the end 21 of the scraper strip 2 and the wiper 5 are both arranged downward, and the third base body 33 connects the first base body 31 and the second base body 32. Of course, at this time, the second base body 32 and the third base body 33 can be arranged separately or connected as one body.

[0078] like Figure 2-Figure 4 As shown, the elastic member 4 is installed at the position corresponding to the scraper 2, specifically, the elastic member 4 is installed between the first base 31 and the third base 33, that is, the first base 31 and the third base 33 are arranged in a floating manner, and when the wiping object 5 contacts the surface to be cleaned 7, the elastic member 4 can be deformed. More specifically, as Figure 4 As shown, the end 21 of the scraper bar 2 is located at the first center plane of the scraper bar 2, that is, the plane where L1 is located, and the extension direction of the elastic member 4 is located at the plane where L2 is located. L1 and L2 form an angle, that is, the extension direction of the elastic member 4 forms an angle with the first center plane where the scraper bar 2 is located, so that when the scraper bar 2 scrapes liquid or impurities on the surface of the surface 7 to be cleaned, it is ensured that the second edge 212 of the end 21 of the scraper bar 2 is against the surface 7 to be cleaned.

[0079] With such an arrangement, when the wiping material 5 is ensured to be in contact with the surface to be cleaned 7, when encountering a curved surface to be cleaned 7, the scraping strip 2 floats relative to the third base body 33, and the end 21 of the scraping strip 2 can also be pressed against the surface to be cleaned 7, and the pressure is appropriate, ensuring that the wiping material 5 and the end 21 of the scraping strip 2 are pressed against the surface to be cleaned 7 at the same time, and the cleaning effect is good.

[0080] More specifically, under the premise that the wiping material 5 is in contact with the surface of the surface to be cleaned 7, when the scraping strip 2 encounters a curved protrusion on the surface of the surface to be cleaned 7, the elastic member 4 can be compressed. When the scraping strip 2 encounters a curved depression on the surface of the surface to be cleaned 7, the elastic member 4 stretches and drives the scraping strip 2 into the curved depression, ensuring that the end 21 of the scraping strip 2 is always in contact with the surface to be cleaned 7.

[0081] like Figure 4 As shown, at this time, the second edge 212 of the end 21 of the scraper strip 2 is in contact with the surface to be cleaned 7. Of course, in order for the first edge 211 of the end 21 of the scraper strip 2 to also be in contact with the surface to be cleaned 7, the scraper strip 2 is configured to be rotatably connected to the mounting seat 3, specifically, rotatably connected to the first seat body 31, so that both the first edge 211 and the second edge 212 can be in contact with the surface to be cleaned 7.

[0082] Specifically, such as Figure 5 、 Figure 6 As shown, an arcuate groove is formed on the first seat body 31, and a portion of the arcuate groove extends radially outward to form a travel groove 34, and the center line of the travel groove 34 coincides with the center line of the first seat body 31; an arcuate wall surface adapted to the arcuate groove is formed on a portion of the outer wall of the scraper strip 2, and a portion of the arcuate wall surface extends radially outward to form a limiting protrusion 35, and the center line of the limiting protrusion 35 coincides with the center line of the scraper strip 2; the limiting protrusion 35 can extend into the travel groove 34, so that the travel groove 34 limits the rotation range of the limiting protrusion 35, that is, the travel groove 34 limits the rotation angle of the scraper strip 2.

[0083] Of course, if Figure 7 、 Figure 8 As shown, the elastic member 4 can also be installed at the position corresponding to the wiper 5. Specifically, the elastic member 4 is installed between the second seat body 32 and the third seat body 33, that is, the second seat body 32 and the third seat body 33 are floatingly arranged. At this time, the first seat body 31 and the third seat body 33 can be separately arranged or connected as one.

[0084] At this time, the extension direction of the elastic member 4 (the plane where L4 lies) also forms an angle with the first central plane of the scraper strip 2 (the plane where L3 lies). This ensures that the scraper strip 2 adheres to the surface 7 to be cleaned. When the scraper strip 2 encounters a curved surface 7 to be cleaned, the wiper 5 floats relative to the third base 33, allowing the wiper 5 to adhere to the surface 7 to be cleaned over the largest possible area. This ensures that the scraper strip 2 and the wiper 5 adhere to the surface 7 to be cleaned simultaneously and work together to achieve their desired cleaning effect.

[0085] like Figure 10 、 Figure 11 As shown, in order to ensure that the first edge 211 and the second edge 212 of the end 21 of the scraper strip 2 can both abut against the surface to be cleaned 7, the scraper strip 2 is also configured to be rotatably connected to the first base 31. Specifically, a shaft 314 is formed on the scraper strip 2, and the shaft 314 is rotatably connected to the third base 33.

[0086] To facilitate the automatic resetting of the scraper strip 2, a resetting protrusion 315 is formed at the top of the shaft 314. A retaining seat 331 adapted to the resetting protrusion 315 is formed on the third base 33. Inclined surfaces 332 are formed on either side of the retaining seat 331. When the shaft 314 rotates relative to the shaft 314, the resetting protrusion 315 deforms. However, the scraper strip 2 automatically repositions itself due to its own elasticity and the inclined surfaces 332. The first center plane of the scraper strip 2 can also be arranged at an angle to the extension direction of the elastic member 4.

[0087] like Figure 12-Figure 19 As shown, in another embodiment, the mounting base 3 includes a first base body 31 and a second base body 32. The scraper strip 2 is connected to the first base body 31, and the wiper 5 is connected to the second base body 32. The elastic member 4 is disposed between the first base body 31 and the second base body 32, that is, the first base body 31 and the second base body 32 are floatingly disposed.

[0088] like Figures 14-18 As shown, the first base body 31 has an extension arm 311, and the second base body 32 forms a channel 321 for the extension arm 311 to extend into. The extension arm 311 is movably connected in the channel 321, and the opening height of the channel 321 toward the first base body 31 is greater than the thickness of the extension arm 311, so that the extension arm 311 can move at the opening of the channel 321. Specifically, Figure 17 The direction shown is an example of up and down swinging. Here, the movement of the extension arm 311 includes swinging, and may also include movement in other directions, which is not specifically limited.

[0089] The floating setting of the first base body 31 and the second base body 32 allows the scraper 2 to swing up and down with a larger amplitude, which is beneficial for the scraper 2 to float effectively while ensuring that a large area of ​​the wiping material 5 is in contact with the surface to be cleaned 7, ensuring that the end 21 of the scraper 2 and the wiping material 5 act on the surface to be cleaned 7 at the same time.

[0090] More specifically, the extension arm 311 is rotatably connected to the channel 321, and a rotation fulcrum is formed at the end of the extension arm 311. Specifically in this embodiment, the rotation fulcrum is the rotation shaft 312. A rotation groove 322 for the rotation shaft 312 to be inserted into is formed on the side of the second base 32 away from the first base 31. When the assembly is completed, the rotation shaft 312 is rotatably connected to the rotation groove 322, so that the extension arm 311 swings around the rotation shaft 312 as the center point, driving the scraper strip 2 to float along with the first base 31. Figure 17 Up and down swing in direction.

[0091] To facilitate installation of the elastic member 4, a stopper is formed on the extension arm 311 to engage with the elastic member 4. Specifically, in this embodiment, the extension arm 311 forms a stopper slot 313 into which the elastic member 4 extends. One end of the elastic member 4 extends into the stopper slot 313 to abut against the extension arm 311, while the other end abuts against the second base 32, thereby achieving a floating arrangement between the first base 21 and the second base 32. Of course, the stopper can also be a stopper post structure, with one end of the elastic member 4 sleeved onto the stopper post. In this embodiment, the elastic member 4 can be a spring or a torsion spring. If the elastic member 4 is a torsion spring, it can be assembled at the rotating shaft 312. Of course, the elastic member 4 can also be another existing structure as long as it can perform the deformation function.

[0092] Of course, in the above structure, while the elastic member 4 is provided between the first base body 21 and the second base body 32 , an elastic member may also be provided between the wiper strip 2 and the first base body 21 .

[0093] like Figure 24-27 As shown, the number of the first base bodies 31 can also be two, which are arranged on opposite sides of the second base body 32. At this time, the ends of the extension arms 311 of the two first base bodies 31 are arranged close to each other, and the second base body 32 is provided with two rotating grooves, and the two first base bodies 31 each swing up and down relative to the second base body 32.

[0094] like Figures 28-31 As shown, to facilitate cleaning of outdoor glass surfaces awaiting cleaning, at least two revolving joints are provided between the handle 1 and the mounting base 3. In this embodiment, the revolving joints include a first revolving joint 61 and a second revolving joint 62. The first revolving joint 61 is provided between the first segment 11 and the second segment 12 of the handle 1, while the second revolving joint 62 is provided between the second segment 12 and the mounting base 3.

[0095] like Figure 29As shown, the first rotation joint 61 includes an inner gear ring 611 located one circle inside the first ring 616, a limiter 612 located inside the second ring 617 and coaxially arranged with the inner gear ring 611, a locking member 613 that can be coaxially inserted into the two rings, and a first reset member (not shown in the figure) that abuts against the locking member 613. A third ring 618 is also provided at a position directly opposite the second ring 617, so that the second ring 617 and the third ring 618 clamp the first ring 616, and the locking member 613 connects the first ring 616 and the second ring 617 and the third ring 618 together. The locking member 613 is divided into two parts that interlock with each other, one part of which can move against the first reset member, that is, a part of the locking member 613 can compress the first reset member, and the other end of the first reset member abuts against the third ring 618. The outer wall of the locking member 613 forms a protruding tooth 615 , and the inner wall of the limiting member 612 has a limiting groove 614 , which is opposite to some teeth of the inner gear ring 611 . The part between adjacent limiting grooves 614 on the limiting member 612 blocks part of the inner gear ring 611 .

[0096] When external force is applied to the part of the locking member 613 corresponding to the third ring 618 and the first reset member is compressed, so that the convex tooth 615 is away from the limiting groove 614, the first ring 616 and the second ring 617 can rotate to any angle. When the external force is stopped and the locking member 613 is automatically reset under the action of the first reset member, the convex tooth 615 falls into the limiting groove 614 and passes through the limiting groove 614 and falls into the teeth of the inner gear ring 611 corresponding to the limiting groove 614. The first ring 616 and the second ring 617 are unable to rotate relative to each other due to the action of the convex tooth 615, and the limiting is achieved, thereby positioning the first ring 616 and the second ring 617 at the target position, that is, the first segment 11 and the second segment 12 are at a certain angle.

[0097] like Figure 30 、 Figure 31 As shown, the second rotational joint 62 includes a button 621, a locking post 622 connected to the button 621, a locking hole 623 for inserting the locking post 622, and a second return member (not shown). The number of locking holes 623 is at least two, spaced apart along the arc. The second return member abuts against the locking post 622, thereby driving the locking post 622 to remain inserted into the locking hole 623. A portion of the button 621 extends through the travel slot 121 on the side wall of the second segment 12, thereby facilitating the application of external force.

[0098] During use, external force is applied to the button 621 to disengage the lock column 622 from the lock hole 623. At this time, the second section 12 and the mounting base 3 can rotate freely. By switching the lock column 622 to extend into different lock holes 623, the angle between the mounting base 3 and the gripping rod 1 can be changed to adapt to different usage scenarios.

[0099] The above specific implementation methods are used to illustrate the present invention rather than to limit the present invention. Any modifications and changes made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
