[0025] Example two

[0026] Please refer to Figures 1-6 The surface of storage box 1 is fixedly connected with mounting plate 2, the surface of mounting plate 2 is provided with mounting hole 22, which facilitates the installation of storage box 1 on the wall, the surface of mounting seat 9 is sleeved with protective shell 16, the surface of mounting seat 9 is fixedly connected with fixed plate 17, the surface of protective shell 16 is fixedly connected with sleeve 18, the inside sliding connection of sleeve 18 has bolt 19, the surface of bolt 19 is fixedly connected with pull rod 20, the surface of pull rod 20 is sleeved with spring 21, bolt 19 is inserted in the inside of fixed plate 17, which can protect the bristles on brush 10 from wind and sun, delay the weathering and aging speed of bristles, prolong the service life of brush 10, and also facilitate the disassembly and assembly of protective shell 16, further improve the convenience of replacing brush 10.

[0027] Working principle: During use, the storage box 1 is fixed to the wall by inserting the bolts into the mounting holes 22 on the mounting plate 2. When the awning is in use, the motor 8 is started, and the output end of the motor 8 drives the winding roller 3 to rotate forward, so that the canvas 4 is lowered, and the curved arm 5 slowly straightens under the action of the torsion spring inside it and opens the canvas 4 with the cooperation of the front rod 6. After the canvas 4 has been used for a long time, debris such as leaves and dust will fall on the canvas 4. When cleaning the canvas 4, the motor 8 is started, and the motor 8 drives the winding roller 3 to rotate in the opposite direction to retract the canvas 4. During the retraction process of the canvas 4, the curved arm 5 and the front rod 6 retract together with it. During the retraction process of the canvas 4, the bristles on the brush 10 can automatically clean the leaves and dust on the canvas 4. When the brush 10 is replaced, the knob is turned, and the knob 13 drives the screw 12 to rotate inside the sleeve 11. One end of the screw 12 is disengaged from the fixing hole 15 on the brush 10, and then the brush 10 is removed from the mounting hole 15. The inner part of the mounting seat 9 can be pulled out, so that leaves and dust on the canvas 4 can be cleaned. The automatic cleaning function significantly improves the convenience of maintenance. There is no need for manual frequent cleaning, which reduces safety risks, saves manpower and time costs, and effectively keeps the awning clean and maintains the sunshade and rainproof performance. It is also convenient for the brush 10 to be quickly replaced after long-term use. The protective shell 16 is sleeved on the mounting seat 9, and the pin 19 is slidably connected to the inside of the sleeve 18. One end of the pin 19 is inserted into the inside of the fixing plate 17, and the pull rod 20 is fixedly connected to the pin 19. The spring 21 is sleeved on the outer periphery of the pull rod 20, so that the bristles on the brush 10 can be protected to prevent the bristles from being exposed to wind and sun, which is beneficial to delaying the weathering and aging of the bristles and extending the service life of the brush 10. At the same time, it is convenient for the protective shell 16 to be disassembled and assembled in the later stage, further improving the convenience of replacing the brush 10 in the later stage. When the light is insufficient, the lighting lamp 7 on the curved arm 5 can be turned on for lighting.

[0028] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields.
