[0026] Preferably, a support plate 8 is provided on the brush body 1 or the cleaning head 3, and the support plate 8 cooperates with the cleaning head 3 so that the cleaning head 3 as a whole can simultaneously contact and clean the surface to be cleaned. When the cleaning brush is cleaning, the upper end of the bristles or the wiping material needs to be supported so that the lower end thereof is located on the same plane to simultaneously clean the surface to be cleaned. The provision of the support plate 8 can support the bristles or the wiping material to prevent it from sinking or moving into the brush body 1.

[0027] In this embodiment, the cleaning head 3 can be a traditional cleaning head 3, that is, the bristles are installed on the support plate 8 by means of hair planting processing, so that the support plate 8 and the bristles together constitute the cleaning head 3, or the bristles can be installed on a flexible cloth strip by hair planting, and the cloth strip and the bristles constitute the cleaning head 3, or the support plate 8, the cloth strip and the bristles together constitute the cleaning head 3.

[0028] In other embodiments, the cleaning head 3 may be formed by fixing a wiping material on the support plate 8, such as arranging short fluff or short bristles on a cloth strip to form a window screen brush, or fixing a mop, sponge, or scouring pad on the support plate 8 to form a mop, so as to increase the cleaning methods of the cleaning brush.

[0029] In this embodiment, the outer periphery of the brush body 1 extends downward to form a surrounding frame 9, which encloses a concave cavity. The active cavity 5 is connected to the concave cavity, and a block is provided on the concave cavity. The top surface of the cleaning head 3 is provided with a support plate 8. The upper end of the support plate 8 is connected to a connecting piece 7. The connecting piece 7 enters the active cavity 5 and cooperates with the quick release mechanism for positioning. The block is supported on the top surface of the support plate 8, and the bottom surface of the cleaning head 3 is flush with the surrounding frame 9 or is located below the surrounding frame 9.

[0030] In other embodiments, the outer periphery of the brush body 1 extends downward to form a surrounding frame 9, and the surrounding frame 9 encloses a concave cavity. A buckle 10 is provided on the inner side of the surrounding frame 9, and the support plate 8 is installed on the concave cavity through the buckle 10. A through hole 11 is provided in the middle of the support plate 8, and the connector 7 is installed on the top surface of the cleaning head 3. The connector 7 passes through the through hole 11 and cooperates with the quick release mechanism to position, and the support plate 8 fits the top surface of the cleaning head 3 to prevent the cleaning head 3 from entering the concave cavity. When the bristles are planted on a cloth strip or the cleaning head 3 is set as a wiping object such as a mop, the support plate 8 can support the soft cloth strip or wiping object.

[0031] In the above embodiment, the knob 6 is hollow, a first limiting portion 12 is provided on the inner side of the side wall, a second limiting portion 13 is provided on the connecting member 7, the first limiting portion 12 and the second limiting portion 13 form a quick release mechanism, the connecting member 7 enters the knob 6 upward, the second limiting portion 13 is displaced with the first limiting portion 12, the knob 6 is rotated, the first limiting portion 12 moves to the bottom of the second limiting portion 13 and abuts against the second limiting portion 13, so as to prevent the cleaning head 3 from moving downward away from the brush body 1. A spring button 14 is also provided on the outer side of the knob 6, a retaining ring 15 is provided on the connecting seat 4, a boss 16 is provided on the retaining ring 15, the spring button 14 cooperates with the retaining ring 15 to position the knob 6 and the connecting seat 4 up and down, when the knob 6 is rotated, the spring button 14 slides along the retaining ring 15 until the spring button 14 abuts against the boss 16, and the first limiting portion 12 is located at a position displaced with the second limiting portion 13.

[0032] In other embodiments, the quick release mechanism can also be set as a gear transmission structure. Specifically, the quick release mechanism includes a gear 17 and a limit member 18. The gear 17 is fixed below the knob 6 and can rotate simultaneously with the knob 6. The limit member 18 is provided with one or two. A rack 19 is provided at one end of the limit member 18, and a third limit portion 20 is provided at the other end. The knob 6 drives the limit member 18 to move through the gear 17 and the rack 19, so that the third limit portion 20 is matched with the second limit portion 13 on the connecting member 7 for positioning. The connecting seat 4 is provided with a sleeve, and a socket 21 is provided on the side of the sleeve. The third limit portion 20 can extend or retract from the socket 21 to position or separate from the second limit portion 13.

[0033] Preferably, there is an inclined angle between the brush body 1 and the handle 2, and when the bottom surface of the cleaning head 3 is parallel to the surface to be cleaned, the handle 2 is inclined away from the surface to be cleaned, and a wiper 22 is provided on the brush body 1 or the connecting seat 4, and the wiper 22 extends away from the cleaning head 3. When the user mops the floor or cleans high glass or walls, the entire cleaning head 3 is in contact with the surface to be cleaned, and there is a gap between the position at the end of the handle 2 for the hand to hold and the surface to be cleaned, which is convenient for the user to operate cleaning.

[0034] The connecting base 4 and the brush body 1 are rotatably connected. When the connecting base 4 rotates relative to the brush body 1, the knob 6 and the quick-release mechanism remain stationary, which is convenient for adjusting the angle between the handle 2 and the cleaning head 3. When the angle is adjusted, the cleaning head 3 will not separate from the quick-release mechanism due to the angle change.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
