[0030] In combination with Figures 1 to 4 the glass cleaner of the present utility model will be further described.

[0031] A glass cleaner, characterized in that it comprises a handle, a joint assembly 1 provided at the head of the handle, and a cleaning component 2 provided on the joint assembly 1. The joint assembly 1 includes a pipe joint 13, a bracket joint 12, and a mounting bracket 11.

[0032] The mounting bracket 11 is a Y-shaped structure, with a first connecting frame 111 and a second connecting frame 112 at the upper end. The cleaning component 2 is divided into a panel assembly 22 and a wiper strip assembly 21. The panel assembly 22 and the wiper strip assembly 21 are respectively installed on the first connecting frame 111 and the second connecting frame 112 to realize the two wiping functions on both sides of the cleaner.

[0033] The panel assembly 22 includes a panel 221 and a back plate 222. On the back of the panel 221, there are clamping claws 2211. On the top of the first connecting frame 111, there is a connecting shaft 1111 for the clamping claws 2211 to engage with and a limit clamping block 1112 for defining the rotation angle of the panel assembly 22.

[0034] The first connecting frame is of a U-shaped structure, and the connecting shaft 1111 is fixed at the U-shaped opening of the U-shaped structure. The clamping claw 2211 includes an upper clamping plate 22111 and a lower clamping plate 22113. Between the upper clamping plate 22111 and the lower clamping plate 22113, there is a clamping opening 22112 for the connecting shaft 1111 to be inserted into. The width of the clamping opening 22112 at the corresponding opening position is smaller than the width at the corresponding internal position, preventing the problem that the connecting shaft 1111 accidentally slips out of the clamping opening 22112. The limit clamping block 1112 is formed on the connecting shaft 1111 and has an upper supporting surface 11122 for the upper clamping plate 22111 to abut against and a lower supporting surface 11121 for the lower clamping plate 22113 to abut against. The upper supporting surface 11122 is a horizontal plane or close to horizontal, and the lower supporting surface 11121 is an inclined plane, and an angle of 30 - 60° is formed between the lower supporting surface 11121 and the upper supporting surface 11122. In this embodiment, the angle is 45°, enabling the panel assembly 22 to rotate within a range of 45°, facilitating the panel assembly 22 to face the surface to be wiped, and thus facilitating wiping use.

[0035] The clamping claw 2211 further includes two side baffles 22114, which are located on the left and right sides of the clamping opening 22112. There are two limit clamping blocks 1112, which are axially distributed along the connecting shaft 1111 and respectively abut against the inner sides of the two side baffles 22114, so that the clamping claw 2211 is limited left and right, enhancing the stability of the clamping claw 2211 when it is mounted on the connecting shaft 1111.

[0036] The squeegee assembly 21 includes a squeegee 211 and a squeegee holder 212. On the top of the second connecting frame 112, there is a socket 1122, and on the side wall of the socket 1122, there is an elastic buckle 1121; on the back of the squeegee holder 212, there is an insertion tube 2121, and it is inserted onto the socket 1122 through the insertion tube 2121, and then the elastic buckle 1121 is engaged with the elastic buckle groove on the side wall of the insertion tube 2121 for fixation; on the front of the squeegee holder 212, there is an installation groove 2122, and the squeegee 211 slides into the installation groove 2122 from the end of the squeegee holder 212 and is arranged in the installation groove 2122.

[0037] The lower end of the pipe joint 13 is for the upper end of the handle to be inserted therein to achieve connection with the handle. The upper end of the pipe joint 13 is hinged to the lower end of the support joint 12, enabling the upper end of the support joint 12 to rotate back and forth. A first anti-rotation structure 14 is provided between the support joint 12 and the pipe joint 13 to prevent the support joint 12 from rotating freely relative to the pipe joint 13. The cleaning component 2 is installed at the upper end position of the mounting bracket 11, and the lower end of the mounting bracket 11 is hinged to the upper end of the support joint 12, enabling the upper end of the mounting bracket 11 to rotate left and right. A second anti-rotation structure is provided between the mounting bracket 11 and the support joint 12 to prevent the mounting bracket 11 from rotating arbitrarily relative to the support joint 12.

[0038] At the upper end of the pipe joint 13, there are a first connecting ring 131 and a second connecting ring 132 that are docked and isolated. At the lower end of the support joint 12, there is a third connecting ring 121. The third connecting ring 121 is disposed between the first connecting ring 131 and the second connecting ring 132. At the same time, a rotating shaft is inserted through the three of them to achieve the relative rotation of the support joint 12 relative to the pipe joint 13.

[0039] In order to limit the rotation angle of the support joint 12 relative to the pipe joint 13, a limiting strip 1212 is provided on the outer side wall of the third connecting ring 121. When the support joint 12 rotates from a state parallel to the pipe joint 13 to a state perpendicular to the pipe joint 13, the limiting strip 1212 abuts against the upper end wall of the pipe joint 13, restricting the upper end of the support joint 12 from continuing to rotate downward. There are two such limiting strips 1212, enabling the support joint 12 to be rotationally restricted in both the front and rear directions.

[0040] The first anti-rotation structure 14 includes a first positioning groove 1311 on the inner wall of the first connecting ring 131, a plurality of second positioning grooves 1211 on the inner wall of the third connecting ring 121 and distributed around the center of the circle, a positioning block 144 on the outer side wall of the rotating shaft and fitting in the first positioning groove 1311, and a spring 142 provided between the rotating shaft and the second connecting ring 132. Among them, the rotating shaft can axially move in the first connecting ring 131, the second connecting ring 132, and the third connecting ring 121. The spring 142 provides a pulling force towards the second connecting ring 132 for the rotating shaft, causing the positioning block 144 to enter the second positioning groove 1211, so that the positioning block 144 is simultaneously located in the first positioning groove 1311 and the second positioning groove 1211, restricting the rotation of the support joint 12 relative to the pipe joint 13; by pressing the rotating shaft to make the rotating shaft move towards the first connecting ring 131 direction, the positioning block 144 exits the second positioning groove 1211, and then the support joint 12 can be rotated.

[0041] Both the inner walls of the first connecting ring 131 and the second connecting ring 132 have inner steps. The rotating shaft includes a shaft body 143 and a button cover 141. One end of the shaft body 143 corresponding to the first connecting ring 131 has a limiting shoulder 1431 with an increased diameter and capable of supporting on the first connecting ring 131. That is, in the natural state, the spring 142 pulls the rotating shaft toward the second connecting ring 132 side, so that the limiting shoulder 1431 on the shaft body 143 abuts against the inner step on the inner wall of the first connecting ring 131 for fixation. In this state, the positioning block 144 is simultaneously located in the first positioning groove 1311 and the second positioning groove 1211. The button cover 141 is clamped on one end of the shaft body 143 facing away from the limiting shoulder 1431, and the diameter of the button cover 141 is larger than that of the shaft body 143. The spring 142 is sleeved on the shaft body 143, and its two ends are respectively pressed against the inner step on the inner wall of the second connecting ring 132 and the button cover 141, providing a pulling force toward the second connecting ring 132 for the rotating shaft.

[0042] The shaft body 143 is a tubular structure, and has two symmetric card slots 1432 on its side wall. The button cover 141 has two elastic card feet 1411. Therefore, the button cover 141 is fixed at the end position of the shaft body 143 through the engagement of the elastic card feet 1411 and the card slots 1432.

[0043] An articulated groove 122 is provided at the upper end position of the bracket joint 12. The lower end of the mounting bracket 11 is fitted in the articulated groove 122 through a pin shaft 113. That is, connection holes are provided on both side walls of the articulated groove 122, and connection holes are also provided at the lower end position of the mounting bracket 11. The pin shaft 113 is simultaneously inserted into the connection holes on the side wall and the connection holes of the mounting bracket 11 to realize the rotational connection between the mounting bracket 11 and the bracket joint 12.

[0044] A friction block 15 is provided at the bottom of the articulated groove 122. The top of the friction block 15 contacts the lower end of the mounting bracket 11, providing a resistance to the rotation of the mounting bracket 11 to prevent the mounting bracket 11 from rotating randomly in the natural state.

[0045] During use, the limit block 1112 can limit the rotation angle of the panel assembly 22, facilitating the user to press the panel assembly 22 against the wiping surface when holding the handle, which is convenient for use.

[0046] The squeegee assembly 21 and the panel assembly 22 are adjusted in angle in four directions of front, back, left and right relative to the handle. At the same time, the panel assembly 22 can also rotate relative to the first connecting frame 111, which can significantly increase the wiping angle of the cleaning component 2 and facilitate the use of the operator.

[0047] The panel assembly 22 is snap-connected to the first connecting frame 111, and the scraping strip assembly 21 is sleeved on the second connecting frame 112, which has the characteristics of being convenient for insertion and replacement.
