[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts fall within the scope of protection of this application.

[0037] The embodiments of this application provide a cleaning brush with a retractable and foldable handle, which can solve the problem in the related art that it is inconvenient to store or carry when the handle is long.

[0038] See Figures 1 to 4 As shown, the embodiments of this application provide a cleaning brush with a retractable and foldable handle, including:

[0039] A cleaning brush body, which includes a cleaning brush head 10. The cleaning brush head 10 is used to cooperate with cleaning structures such as bristles, a rag, or a windshield wiper. A handle 20 is connected to the cleaning brush head 10. The handle 20 includes a first section 21 and a second section 22. The first section 21 and the second section 22 are used to connect to each other to extend or shorten the length of the handle 20.

[0040] A folding mechanism 30, which includes a connecting plate 31 rotatably connected between the first section 21 and the second section 22. One end of the connecting plate 31 is rotatably connected to the first section 21, and the other end of the connecting plate 31 is rotatably connected to the second section 22. The first section 21 and the second section 22 are rotatably connected to each other with the connecting plate 31 as the rotation axis to achieve folding or lengthening actions.

[0041] An unfolding mechanism 40, which includes a first sleeve 41 fixedly sleeved on the first section 21, and a second sleeve 42 slidably connected to the second section 22 and detachably connected to the first sleeve 41.

[0042] When the first section 21 and the second section 22 need to be folded, the second sleeve 42 is detached from the first sleeve 41 and slides in a direction away from the second sleeve 42 and is located on the second section 22. At this time, the first section 21 and the second section 22 are folded with the connecting plate 31 as the rotation axis.

[0043] When the first section 21 and the second section 22 need to be unfolded and extended, the second sleeve 42 slides on the second section 22 in a direction close to the first sleeve 41 and is connected to the first sleeve 41. At this time, the second sleeve 42 is coaxially sleeved on the first section 21 and the second section 22, so that the first section 21 and the second section 22 are coaxially and fixedly connected to each other.

[0044] In the cleaning brush with a retractable and foldable handle according to the embodiment of the present application, the handle 20 is set into two mutually independent first sections 21 and second sections 22, and the first section 21 and the second section 22 are connected by a folding mechanism 30.

[0045] The folding mechanism 30 uses a connecting plate 31 to rotatably connect between the first section 21 and the second section 22, so that the first section 21 and the second section 22 can fold and unfold with the connecting plate 31 as the rotation axis. After the handle 20 is folded, it is convenient for the storage of the cleaning brush.

[0046] An unfolding mechanism 40 is also provided between the first section 21 and the second section 22. The first sleeve 41 of the unfolding mechanism 40 is fixed on the first section 21, and the second sleeve 42 of the unfolding mechanism 40 is slidably connected to the second section 22 and is detachably connected to the first sleeve 41, so that the first section 21 and the second section 22 are coaxially fixed to each other after being unfolded, and the cleaning brush can extend for cleaning operations.

[0047] In some alternative embodiments: Refer to Figures 3 to 5 As shown, the embodiment of the present application provides a cleaning brush with a retractable and foldable handle. Both the first section 21 and the second section 22 of the cleaning brush are hollow stainless steel tube structures, and mounting seats 32 are fixedly connected to the ends of the first section 21 and the second section 22 that are close to each other.

[0048] An installation groove 33 for partially extending into the connecting plate 31 is opened at one end of the mounting seat 32. One end of the connecting plate 31 is located in the installation groove 33 and is rotatably connected to the mounting seat 32. The mounting seat 32 is a cylindrical structure and is fixedly installed inside the first section 21 and the second section 22. The installation groove 33 provides a rotation space for the connecting plate 31 in the mounting seat 32.

[0049] The installation groove 33 of the mounting seat 32 penetrates through the side wall of the mounting seat 32, so that the rotation angle of the connecting plate 31 in the installation groove 33 of the mounting seat 32 is greater than 90 degrees. Cuts are opened at the ends of the first section 21 and the second section 22 that are close to each other to avoid the rotation of the connecting plate 31. When the first section 21 and the second section 22 are in the folded state, the first section 21 and the second section 22 are parallel to each other side by side.

[0050] In some alternative embodiments: Refer to Figures 3 to 5 As shown, the embodiment of the present application provides a cleaning brush with a retractable and foldable handle. Both ends of the connecting plate 31 of the cleaning brush are arc-shaped structures, and shaft holes are opened at both ends of the connecting plate 31. The mounting seat 32 is fixed to the first section 21 and the second section 22 by stainless steel locking screws 34, and the stainless steel locking screws 34 pass through the shaft holes of the connecting plate 31. The connecting plate 31 rotates 90 degrees in both forward and reverse directions around the mounting seat 32 with the stainless steel locking screw 33 as the rotation axis.

[0051] The stainless steel snap-lock screw 34 uses a sub-nail and a mother-nail made of stainless steel material to be threadedly connected to each other. One stainless steel snap-lock screw 34 fastens and connects the mounting seat 32, the first section 21 and the connecting plate 31 together, improving the stability of the connection between the mounting seat 32, the first section 21 and the connecting plate 31, serving the purposes of anti-loosening and anti-rust, and improving the rotational flexibility and service life of the handle 20.

[0052] Another stainless steel snap-lock screw 34 fastens and connects the mounting seat 32, the second section 22 and the connecting plate 31 together, improving the stability of the connection between the mounting seat 32, the second section 22 and the connecting plate 31, serving the purposes of anti-loosening and anti-rust, and improving the rotational flexibility and service life of the handle 20.

[0053] In some alternative embodiments: Refer to Figures 1 to 3 and Figure 6 As shown, the embodiment of the present application provides a cleaning brush with a retractable and foldable handle. The first sleeve 41 of the cleaning brush is fixed on the first section 21 through the stainless steel snap-lock screw 34. One end of the first sleeve 41 close to the second sleeve 42 is provided with an external thread.

[0054] The length of the second sleeve 42 is greater than the length of the connecting plate 31. When the second sleeve 42 is connected to the first sleeve 41, the overlapping length between the second sleeve 42 and the first section 21 and the second section 22 is longer, thereby improving the stability of the connection after the first section 21 and the second section 22 are unfolded and extended.

[0055] One end of the second sleeve 42 close to the first sleeve 41 is provided with an internal thread for connecting with the first sleeve 41. The internal thread of the second sleeve 42 is threadedly connected to the external thread of the first sleeve 41, facilitating the mutual connection and disassembly of the first sleeve 41 and the second sleeve 42. The outer wall of the second sleeve 42 is provided with anti-slip lines 43, which are used for anti-slip when holding the second sleeve 42 by hand.

[0056] In some alternative embodiments: Refer to Figures 1 to 3 As shown, the embodiment of the present application provides a cleaning brush with a retractable and foldable handle. The handle 20 of the cleaning brush further includes a third section (not shown in the figure) coaxially located inside the second section 22 and telescopically and slidably connected to the second section 22. One end of the second section 22 away from the first section 21 is provided with a locking device 24 for locking the third section, and a handle 23 is connected to the end of the third section.

[0057] In the embodiment of the present application, a third section is further provided at the end of the second section 22 and is telescopically and slidably connected thereto. After the third section extends out of the second section 22, it can further increase the length of the handle 20. When the third section retracts into the second section 22, it is convenient to store and carry the cleaning brush. The lock 24 is used to lock the third section so that the third section maintains a set extended length.

[0058] In some alternative embodiments: Refer to Figures 1 to 3 As shown, the embodiment of the present application provides a cleaning brush with a telescopic and foldable handle. The handle 20 of the cleaning brush further includes a fourth section 25 detachably connected to the first section 21. The fourth section 25 and the first section 21 are connected by a threaded sleeve 50.

[0059] At one end of the fourth section 25 away from the first section 21, a mounting head 26 for rotatably connecting the cleaning head 10 is fixedly connected. The cleaning head 10 can rotate flexibly on the mounting head 26, thereby facilitating the adjustment of the cleaning angle of the cleaning head 10. The fourth section 25 is a hollow tubular structure and is a bent pipe, so that the cleaning head 10 can conveniently clean objects at a relatively high position.

[0060] In some alternative embodiments: Refer to Figures 1 to 3 As shown, the embodiment of the present application provides a cleaning brush with a telescopic and foldable handle. The threaded sleeve 50 of the cleaning brush includes an external threaded sleeve 51 fixed on the first section 21 and an internal threaded sleeve 52 fixed on the fourth section 25. The external threaded sleeve 51 and the internal threaded sleeve 52 are threadedly connected to each other so that the first section 21 and the fourth section 25 are coaxially and fixedly connected.

[0061] The fourth section 25 and the first section 21 are detachably connected to each other through the internal threaded sleeve 52 and the external threaded sleeve 51. When storing or carrying the cleaning brush, the external threaded sleeve 51 and the internal threaded sleeve 52 are disengaged from each other, so that the fourth section 25 and the first section 21 are in a separated state. When using the cleaning brush, the external threaded sleeve 51 and the internal threaded sleeve 52 are connected to each other, so that the fourth section 25 and the first section 21 are in a coaxial connection state.
