Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Example 1
[0024] like Figures 1-6 As shown, a multi-angle rotating brush head device for cleaning building exterior walls includes a connector 1. A fixed base 2 is rotatably connected to the right side of the outer top of the connector 1 via a rotating shaft. A motor 4 is fixedly connected to the inner side of the fixed base 2. A rotating seat 5 with a cylindrical bottom is fixedly connected to the end of the main shaft of the motor 4, and the rotating seat 5 is rotatably connected to the fixed base 2. A fixed shaft 7 is rotatably connected to the inner side of the rotating seat 5. A large bevel gear 8 is fixedly connected to the outer top of the fixed shaft 7. A small bevel gear 9 is meshed with the outer side of the large bevel gear 8. One end of the connector 1 is fixedly connected to a threaded shaft 10 that is rotatably connected to the rotating seat 5. A cuboid fixed rod 11 is spirally connected to the outside of the threaded shaft 10, and the fixed rod 11 is slidably connected to the rotating seat 5. One end of the fixed rod 11 is fixedly connected to a push rod 12 that contacts the rotating seat 5. A positioning seat 13 contacts the top edge of the inside of the rotating seat 5. A trapezoidal push block 14 is fixedly connected to the bottom of the positioning seat 13. A cleaning brush 15 is placed on the top of the inner side of the positioning seat 13. A controller 22 is fixedly connected to the bottom of the connector 1.
[0025] Example 2
[0026] like Figure 2 As shown, in order to solve the problem of inconvenience in adjusting the cleaning angle of the device, the inner left end of the connector 1 is provided with an internal thread, and the inner right end of the connector 1 is rotatably connected to an electric push rod 3 via a rotating shaft. The other end of the electric push rod 3 is rotatably connected to the fixed base 2 via a rotating shaft. By controlling the extension and retraction of the electric push rod 3, the cleaning angle of the device can be easily adjusted.
[0027] Example 3
[0028] like Figure 2As shown, in order to solve the problem of large friction between the rotating seat 5 and the fixed seat 2 during rotation, a bearing 6 is fixedly connected to the outer side of the cylindrical part at the bottom of the rotating seat 5, and the bearing 6 is fixedly connected to the fixed seat 2. By connecting the cylindrical part at the bottom of the rotating seat 5 to the fixed seat 2 through the bearing 6, large friction between the rotating seat 5 and the fixed seat 2 during rotation can be avoided.
[0029] Example 4
[0030] like Figure 5 As shown, in order to solve the problem that the cleaning brush 15 is not easy to automatically reset when the push rod 12 slides away from the bottom of the push block 14 after the push rod 12 pushes the push block 14 to move the positioning seat 13 and the cleaning brush 15 upward, the positioning seat 13 is fixedly connected to both ends of the positioning seat 13, and the limiting block 16 is slidably connected to the rotating seat 5. The top end of the limiting block 16 is fixedly connected to the spring 17, and the other end of the spring 17 is fixedly connected to the rotating seat 5. After the push rod 12 pushes the push block 14 to move the positioning seat 13 and the cleaning brush 15 upward, the positioning seat 13 will also drive the limiting block 16 to compress the spring 17. When the push rod 12 slides away from the bottom of the push block 14, the elastic force of the spring 17 on the limiting block 16 will cause the positioning seat 13 to automatically reset, which facilitates the automatic reset of the cleaning brush 15.
[0031] Example 5
[0032] like Figure 6 As shown, to address the problem of inconvenience in replacing severely worn cleaning brushes 15, an iron plate 18 is fixedly connected to the bottom of the cleaning brush 15. A magnetic block 19 is attracted to the bottom of the iron plate 18, and the magnetic block 19 is fixedly connected to the positioning seat 13. There are six sets of cleaning brushes 15, and each set contains four cleaning brushes. The four cleaning brushes in each set are a soft-bristled nylon brush, a hard-bristled plastic brush, a wire brush, and a sponge brush. When the cleaning brush 15 is severely worn, pulling the cleaning brush 15 separates the bottom iron plate 18 from the strong magnetic block 19 fixed in the positioning seat 13, making it easy to remove and replace the severely worn cleaning brush 15.
[0033] Example 6
[0034] like Figure 2 and Figure 5As shown, to solve the problem of inconvenience in switching the cleaning brush 15, a worm gear 20 is fixedly connected to the bottom outer side of the fixed shaft 7. A worm 21 that passes through the rotating seat 5 is meshed with the outer side of the worm gear 20, and the worm 21 is rotatably connected to the rotating seat 5. By rotating the worm 21 to mesh with the worm gear 20, the fixed shaft 7 drives the large bevel gear 8 to mesh with the small bevel gear 9, thereby causing the small bevel gear 9 to drive the threaded shaft 10 to be helically connected to the rectangular fixed rod 11. At this time, when the fixed rod 11 drives the push rod 12 to push the push block 14 at the bottom of the positioning seat 13 one by one, the pushed push block 14 simultaneously pushes the corresponding cleaning brush 15 in the positioning seat 13 to move upward, which facilitates the switching of the cleaning brush 15.
[0035] In this embodiment, all electrical appliances in the device are powered externally. When using the device, first connect the connector 1 to the external operating rod. After connection, when cleaning the exterior wall of the building using the device, first rotate the worm gear 21 to engage the worm wheel 20. At this time, the worm wheel 20 will drive the large bevel gear 8 to engage the small bevel gear 9 through the fixed shaft 7. The small bevel gear 9 will drive the threaded shaft 10 to connect with the rectangular fixed rod 11. The fixed rod 11 will drive the push rod 12 to push the trapezoidal push block 14. When the push rod 12 begins to contact the inclined side of the push block 14, as the push rod 12 continues to move, the push block 14 will push the positioning seat 13 upward. The positioning seat 13 will drive the limit block 16 to compress the spring 17, and at the same time, it will also push the corresponding cleaning on the positioning seat 13. Brush 15 is pushed upward from the rotating seat 5. As the push rod 12 pushes the push block 14 at the bottom of the positioning seat 13 one by one, when the cleaning brush 15 required for the corresponding building exterior wall is pushed out, the worm gear 21 stops rotating. Then, the electric push rod 3 is controlled by the controller 22 to extend and retract to adjust the angle of the device. Then, the motor 4 is started to drive the cleaning brush 15 in the rotating seat 5 to rotate and clean the corresponding building exterior wall. During the use of the device, when the cleaning brush 15 is severely worn after long-term use, resulting in a poor cleaning effect during the cleaning of the building exterior wall, the bottom iron plate 18 is separated from the strong magnetic block 19 fixed in the positioning seat 13 by pulling the cleaning brush 15, and the severely worn cleaning brush 15 can be removed and replaced.
