With this arrangement, the hand lever 20 is connected to the wiping head 10 via the link 30, and also rotates relative to the wiping head 10 when the hand lever 20 rotates about the first axis.

Fig. 4 is a schematic view of the handheld lever of the cleaning wipe provided by the embodiment of the present application rotating around the first axis, as shown in fig. 4, when the wiping surface of the wiping head 10 is attached to the glass surface, and as the wiping head 10 moves downward on the glass surface for wiping, the handheld lever 20 rotates around the first axis relative to the connecting member 30 in the direction shown by the arrow N in fig. 4, that is, the handheld lever 20 rotates away from the glass surface.

Alternatively, the hand-held lever 20 can rotate 360 ° about the first axis relative to the link 30 without limitation of other structures. However, depending on the configuration of the cleaning wipe assembly and the use scenario, the hand-held wand 20 may be constrained during rotation about the first axis by other structures, such as the wiping head 10, glass surfaces.

Illustratively, with the hand lever 20 parallel to the glass surface as the initial position in FIG. 4, the hand lever 20 may be rotated counterclockwise about the first axis by 0-180, such as 10, 30, 90, 120, etc., relative to the initial position. Specifically, the rotation angle of the handheld lever 20 is determined according to the position of the wiping head 10 and the standing position of the user, so that the user can make the wiping surface of the wiping head 10 have a good fitting degree with the glass surface by adjusting the rotation angle of the handheld lever 20 without moving the position of the user, and a good wiping and cleaning effect is achieved.

Further, the wiping head 10 is connected to the connection 30 so as to be rotatable about a second axis, which is perpendicular to the wiping surface, i.e. the wiping head 10 is always rotated relative to the connection 30 in the plane of the wiping surface, and can be positioned at a plurality of different angles of rotation.

Fig. 5 is a schematic structural diagram of a cleaning wipe provided by an embodiment of the present application when the wiping head rotates 45 ° around the second axis, and the wiping head 10 in fig. 5 is rotated 45 ° around the second axis in the direction indicated by the arrow O in fig. 5 and is positioned at the initial position of the wiping head 10 shown in fig. 2.

Alternatively, the wiping head 10 can be rotated 360 ° about the second axis relative to the connection 30, and positioned only at certain angles, for example after 30 °, 90 °, 135 ° of rotation of the wiping head 10 relative to the initial position.

It should be understood that after the wiping head 10 is rotated about the second axis and positioned, the hand-held rod 20 can still rotate about the first axis during the wiping operation, i.e. during the movement of the wiping head 10, the hand-held rod 20 can rotate towards or away from the glass surface, so that the wiping surface can be well attached to the glass surface. That is, the rotation of the hand lever 20 about the first axis and the rotation of the wiping head 10 about the second axis do not affect each other.

According to the cleaning wiper provided by the embodiment of the application, the connecting piece 30 is arranged on the side of the cleaning wiper, which is away from the wiping surface, the handheld rod 20 of the cleaning wiper is rotatably connected to the connecting piece 30 around the first axis, that is, the handheld rod 20 is hinged to the connecting piece 30, so that when a user uses the cleaning wiper provided by the embodiment of the application to perform wiping operation, the handheld rod 20 can rotate towards the direction close to or away from the glass surface, and the rotating angle of the handheld rod 20 around the first axis is adjusted according to the position of the wiping head 10, the position where the user stands and the position where the user holds the handheld rod 20. Compare among the prior art handheld pole and clean overhead spring coupling and realize rotating, this application is through being connected handheld pole 20 and connecting piece 30 are articulated for the user makes handheld pole 20 rotate around the primary axis and make the face of cleaning head 10 hug closely the elasticity of need not to overcome the spring when glass surface at the application of force, consequently comparatively laborsaving during the use, use experience better. The hinged rotating structure is flexible, the phenomenon of jamming of the handheld rod 20 in the rotating process can not occur, and the wiping operation of a user can not be influenced; the hinge structure has better structural stability and can prolong the service life of the product. Through the adjustment of the rotation angle of the handheld rod 20 around the first axis, when the user moves the wiping head 10, for example, from the top of the glass to the bottom, the wiping surface of the wiping head 10 can be always tightly attached to the surface of the glass without frequently moving the position of the user, so that the better wiping cleaning effect can be achieved, the use of the user is facilitated, and the use experience of the user is improved. When the corner position of the glass or the outer surface of the glass is cleaned, the wiping surface can be tightly attached to the surface of the glass for wiping cleaning by rotating the hand-held rod 20 to a proper angle around the first axis under the limitation of the standing position.

As shown in fig. 1 to fig. 3, the cleaning wipe provided by the embodiment of the present application further includes a scraper 12, the scraper 12 is disposed on the top of the wiping head 10, and the top of the scraper 12 is inclined to the side away from the wiping surface. When a user wipes the glass by the wiper, the wiping surface is attached to the surface of the glass, and the top of the scraper 12 inclines away from the glass, so that the wiper is not in contact with the surface of the glass, and the resistance is not increased in the wiping process; when the water stain remained on the glass needs to be scraped after the wiping is finished, the cleaning wiper is turned over to make the wiping surface face to the outside (the side facing the user), at this time, the inclined direction of the scraper 12 faces to the surface of the glass and the top of the scraper 12 contacts with the glass, so that the wiping operation can be carried out. At this time, the hand lever 20 is positioned between the glass and the wiping head 10, and rotation along the first axis is restricted.

As shown in fig. 1 to 3, the hand lever 20 includes a U-shaped fork 21 at a distal end thereof, and both ends of an opening of the U-shaped fork 21 are hinged to both sides of the connecting member 30, respectively.

As shown in FIG. 1, one end of the hand-held rod 20 is a U-shaped fork 21 for being hinged to the connecting member 30 and further connected to the wiping head 10, and the other end of the hand-held rod 20 is used for being held by a user and further driving the wiping head 10 to move.

Specifically, as shown in fig. 3, the U-shaped fork body 21 has a U-shaped opening, the connecting member 30 is square, the U-shaped opening is used for accommodating a part of the connecting member 30, two rotating shafts 211 are arranged inside two ends of the opening of the U-shaped fork body 21, that is, the two rotating shafts 211 are arranged oppositely, and two opposite sides of the connecting member 30 are correspondingly provided with rotating shaft holes 327 for the rotating shafts 211 to pass through.

When the hand lever 20 is assembled, the rotating shaft 211 of the U-shaped fork body 21 is opposite to the rotating shaft hole 327 and is directly inserted into the rotating shaft hole 327 from the outside, so that the hand lever 20 is hinged to the connecting piece 30. The rotating shaft 211 can rotate in the rotating shaft hole 327, and the straight line of the rotating shaft 211 is the first axis, so that the handheld rod 20 can rotate around the first axis, that is, the rotating shaft 211, and further adjust the included angle between the handheld rod and the glass.

It should be understood that the distance between the ends of the two rod segments of the U-shaped yoke body 21 where the rotation shaft 211 is arranged may be slightly smaller than the distance between the two rotation shaft holes 327 on the connecting member 30, and the U-shaped yoke body 21 has some elastic deformation capability. So, when assembling handheld pole 20, the U-shaped fork body 21 can outwards (to the direction of keeping away from connecting piece 30) deformation so that penetrate the pivot 211 of both sides respectively in pivot hole 327, and can be after the assembly is accomplished, have suitable extrusion force to inboard connecting piece 30, make pivot 211 can't take place the displacement in the axial of pivot hole 327, guaranteed that handheld pole 20 can not rock for connecting piece 30, structural stability is better, and then can promote user's use and experience.

In this embodiment, the hand-held rod 20 is hinged to the two sides of the connecting member 30 through the U-shaped fork 21 having the U-shaped opening, so that the assembly process is simple and convenient, and the structural stability is good.

Alternatively, the U-shaped yoke 21 may be formed as a unitary structure by an integral molding process and may be connected to other segments of the hand-held pole 20 by screwing, bonding, welding, or the like. For example, the integral molding process includes, but is not limited to, an injection molding process, a 3D printing process, and the like.

The U-shaped fork body 21 is produced by using an integral forming process, so that the production process can be simplified, the production efficiency can be improved, and the production cost can be reduced; the handheld rod 20 is connected through screw connection and other modes, so that transportation can be facilitated, transportation cost is reduced, the assembling process is simple, and operation by a user is facilitated.

Further, the handheld rod 20 further comprises a telescopic rod 22, and by means of the telescopic rod 22, the overall length of the handheld rod 20 can be adjusted, so that the handheld rod can adapt to different application scenes, and convenience is brought to users. For example, when it is desired to wipe glass at a higher position, the length of the hand-held lever 20 may be increased; the length of the hand lever 20 can be shortened when wiping work is performed at a short distance and at a low height.

Fig. 6 is a schematic structural diagram of a wiping head according to an embodiment of the present application, and as shown in fig. 3 and 6, a mounting hole 11 is provided on the wiping head 10, and the mounting hole 11 is used for being mounted in cooperation with the connecting member 30. Specifically, the mounting hole 11 has an opening on a face of the wiping head 10 facing away from the wiping face and extends in the direction of the wiping face, that is, the mounting hole 11 extends in the thickness direction of the wiping head 10.

Alternatively, the mounting hole 11 may be a through hole, i.e., the mounting hole 11 penetrates through the thickness direction of the wiping head 10; the mounting hole 11 may also be a blind hole.

Fig. 7 is a schematic structural diagram of a connector according to an embodiment of the present application, and fig. 8 is a partial schematic structural diagram of a cross-sectional view taken along a-a' in fig. 2, as shown in fig. 7, the connector 30 includes a seat 32 and a rotating disc 31.

As shown in fig. 1, 3, 7 and 8, after the connecting member 30 is installed in the installation hole 11, the seat body 32 is located outside the installation hole 11, and the rotating disc 31 is located inside the installation hole 11.

Specifically, the rotating shaft hole 327 is opened on the seat body 32, so that the hand-held lever 20 is hinged on the seat body 32. In this manner, the seat body 32 is located outside the mounting hole 11, that is, outside the wiping head 10, the rotation of the hand-held rod 20 about the first axis is not hindered, and the assembly of the hand-held rod 20 is facilitated.

As shown in fig. 8, the rotary disc 31 is located in the mounting hole 11, in this case, the rotary disc 31 corresponds to a pivot axis of the wiping head 10, i.e. a second axis, the mounting hole 11 corresponds to a rotation shaft hole, and the rotary disc 31 and the mounting hole 11 can rotate relatively so that the wiping head 10 can rotate around the rotary disc 31. The turntable 31 is telescopically connected to the seat 32 so that the turntable 31 can move up and down in the mounting hole 11, and has a first position and a second position, when the turntable 31 is located at the first position, the wiping head 10 is circumferentially positioned, and when the turntable 31 is located at the second position, the wiping head 10 can rotate relative to the turntable 31.

Specifically, when the rotating disc 31 moves in a direction approaching the seat body 32, it moves upward in the mounting hole 11, and when the rotating disc 31 moves in a direction away from the seat body 32, it moves downward in the mounting hole 11, and the rotating disc 31 moves upward and downward in the mounting hole 11 along the axial direction of the mounting hole 11 to switch between the first position and the second position. By positioning the turntable 31 in the first position, the wiping head 10 can be positioned circumferentially, i.e. the wiping head 10 cannot rotate around the second axis, and thus, when the wiping head 10 is subjected to friction while moving on the glass, the wiping head will not rotate in any direction, and thus the normal wiping operation of the user will not be affected. By having the dial 31 in the second position, the user can rotate the mop head 10 about the second axis and reposition the dial 31 to the first position when rotated to the desired angle, positioning the mop head 10.

Since the fixed disk 34 is fixedly connected to the holder body 32, the fixed disk 34 does not move up and down in the mounting hole 11, and therefore can always be in contact with the surface of the convex tooth 111, and when the wiping head 10 is rotated about the second axis relative to the connector 30, the bottom surface of the convex tooth 111 and the upper surface of the fixed disk 34 slide relative to each other. Thus, in the process of the retractable movement of the turntable 31 relative to the seat 32, the seat 32 keeps the stability of the connection between itself and the wiping head 10 by the abutment of the bottom wall 321 of itself and the inner edge 113 and the abutment of the upper surface of the fixed disk 34 and the convex teeth 111, so that the situations of shaking and the like do not occur.

Fig. 17 is a partial structural schematic view of a cross-sectional view of a cleaning wiper shown in another embodiment of the present application, as shown in fig. 17, rounded corners 60 are provided at the shoulder portions of the protrusions 311, the junction between the bottom wall and the side wall of the groove 112, and the edges of the slot opening (the rounded corners 60 of the groove 112, i.e., the rounded corners 60 formed at the shoulder portions of the bottom ends of the teeth 111 and the junction with the inner surface of the inner rim 113), when the rotational force applied to the wiping head 10 is greater than a threshold value, the protrusions 311 on the turntable 31 can be disengaged from the grooves 112 under the guiding action of the rounded corners 60, so that the wiping head 10 can rotate relative to the turntable 31, and the turntable 31 drives the elastic support 40 to accumulate force through the movable plate 33.

In this case, the user directly applies a force to the wiping head 10 to rotate the wiping head 10 about the second axis, when the rotational force applied to the wiping head 10 is greater than the threshold value, due to the guiding effect of the protrusions 311 and the plurality of fillets 60 on the groove 112, the protrusions 311 can gradually disengage from the groove 112, that is, the rotating disc 31 descends in the mounting hole 11 and moves to the second position, meanwhile, the rotating disc 31 drives the movable plate 33 to move towards the bottom of the seat 32 to accumulate the force of the elastic support 40, and when the wiping head 10 rotates to the position where the protrusions 311 are opposite to the next groove 112, the elastic support 40 drives the rotating disc 31 to return to the first position by moving the movable plate 33. The user may perform multiple rotational operations until the wiping head 10 is rotationally positioned to a desired angle.

Through the arrangement, the user does not need to press the movable plate 33 to drive the turntable 31 before the rotating wiping head 10, and directly applies a large rotating force on the wiping head 10, so that the operation process is simplified, the use is more convenient, and the use experience of the user is improved.

Further, as shown in fig. 15, the connecting member 30 further includes a cover 35 located outside the movable plate 33 and covering the top opening of the seat 32. The cover 35 is fixed on the seat 32, so that the seat 32 is more beautiful.

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.
