DETAILED DESCRIPTION

[0021] The utility model Figures 1 to 5 As shown, an angle-adjustable cleaning brush comprises a handle assembly 10, a brush head assembly 20 and a rotation drive assembly 30 for driving the brush head assembly 20 to rotate an angle, wherein:

[0022] The rotary drive assembly 30 is installed between the handle assembly 10 and the brush head assembly 20. The rotary drive assembly 30 includes a first rotary button 31, a second rotary button 32, a rotary positioning member 33 and a rotary axis 34. The brush head assembly 20 has a brush head motor body 21. The first rotary button 31 and the second rotary button 32 are respectively installed at the two ends of the rotary axis 34. The first rotary button 31 and the second rotary button 32 are both wedge-fitted with the rotary positioning member 33. The rotary positioning member 33 can be elastically arranged close to or away from the side of the rotary axis 34; the brush head motor body 21 can be rotatably connected to the end of the rotary positioning member 33.

[0023] By adopting the first rotating button 31, the second rotating button 32, the rotating positioning member 33 and the rotating axis 34 to adjust the angle of the brush head motor body 21, the angle-adjustable cleaning brush provided in the present application can well solve the problem of sanitary dead corners during cleaning; the brush head motor body 21 can be turned to 45 degrees or 90 degrees, so there is no need to bend over or climb to a high place to clean some sanitary dead corners, thereby improving cleaning efficiency and also improving safety during cleaning.

[0024] The rotation drive assembly 30 further includes a rotation return spring 333 for driving the rotation positioning member 33 to return to its original position. The rotation return spring 333 is disposed between the rotation positioning member 33 and the rotation axis 34 .

[0025] The rotation driving assembly 30 further includes a button return spring for driving the first rotation button 31 and the second rotation button 32 to return to their original positions. The button return spring is disposed between the first rotation button 31 and the second rotation button 32 .

[0026] The design of this electric cleaning brush enables the motor brush head to be used for cleaning at 45-degree and 90-degree angles in multiple directions.

[0027] When the first rotation button 31 and the second rotation button 32 are pressed at the same time, the first rotation button 31 and the second rotation button 32 move toward the rotation axis 34 by pushing the rotation positioning part 33, and the brush head motor body 21 can rotate at an angle of 45 degrees or 90 degrees at this time. After the brush head motor body 21 is rotated at the same time, the first rotation button 31 and the second rotation button 32 are released at the same time, and the button reset spring rebounds to push the first rotation button 31 and the second rotation button 32 back to their original positions, and the rotation reset spring 333 rebounds to push the rotation positioning part 33 back at the same time to lock the brush head motor body 21 at the current rotation angle to prevent it from swinging left and right.

[0028] The first rotating button 31 has a first inclined surface 311 , and the upper end of the rotating positioning member 33 has an upper inclined surface 331 matching the first inclined surface 311 ; the first rotating button 31 and the rotating positioning member 33 are squeezed into a wedge fit through the first inclined surface 311 and the upper inclined surface 331 .

[0029] The second rotating button 32 has a second inclined surface 321 , and the lower end of the rotating positioning member 33 has a lower inclined surface 332 matching the first inclined surface 311 . The second rotating button 32 and the rotating positioning member 33 are squeezed into a wedge fit through the second inclined surface 321 and the lower inclined surface 332 .

[0030] Through the wedge-shaped cooperation between the first inclined surface 311 and the upper inclined surface 331, and the extrusion wedge-shaped cooperation between the second inclined surface 321 and the lower inclined surface 332, it is ensured that when the first rotating button 31 and the second rotating button 32 are pressed, the rotating positioning member 33 is moved closer to the rotating axis 34, thereby realizing the angle adjustment of the brush head motor body 21.

[0031] The brush head assembly 20 further includes a cleaning brush head 22 , which is detachably mounted on the output end of the brush head motor body 21 .

[0032] The handle assembly 10 includes a grip rod, which is detachably connected to the rotation drive assembly 30. A protective pad 11 is sleeved on the grip rod for easy gripping; the protective pad 11 is used to protect the operator.

[0033] The use method and principle of the angle-adjustable cleaning brush are as follows:

[0034] When the first rotation button and the second rotation button are pressed at the same time, the first rotation button and the second rotation button move toward the rotation axis by pushing the rotation positioning part. At this time, the brush head motor body can rotate at an angle of 45 degrees or 90 degrees. After the rotation of the brush head motor body is completed, the first rotation button and the second rotation button are released at the same time. The button reset spring rebounds and pushes the first rotation button and the second rotation button back to their original positions. The rotation reset spring rebounds and pushes the rotation positioning part back at the same time to lock the brush head motor body at the current rotation angle and prevent it from swinging left and right.

[0035] The design focus of the utility model is that the angle of the brush head motor body is adjusted by adopting a first rotating button, a second rotating button, a rotating positioning member and a rotating axis. The angle-adjustable cleaning brush provided by the present application can well solve the problem of sanitary dead corners during cleaning; the brush head motor body can be turned to 45 degrees and 90 degrees, and there is no need to bend over or climb to a high place to clean some sanitary dead corners, which improves cleaning efficiency and also improves safety during cleaning.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
