[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0023] The embodiments of the present utility model provide an environmentally friendly cleaning device for outdoor dead corners of buildings,

[0024] such as Figure 1-4As shown in the figure, it includes a frame 1, a lifting cylinder is installed on the frame 1, there is a connecting block on the lifting cylinder, and a cleaning mechanism is connected to the connecting block. The cleaning mechanism includes a mounting seat 2, a driving motor 3, a brush disk seat 4 and a number of brush bundles 5. The driving motor 3 is fixed on the connecting block, the mounting seat 2 is connected to the output end of the driving motor 3, the brush disk seat 4 is fixed on the mounting seat 2. The brush bundle 5 includes a connecting head 51, a connecting rod 52 and a number of bristles 53. The connecting head 51 is rotatably connected to the brush disk seat 4, the connecting rod 52 is fixedly connected to the lower end of the connecting head 51 and extends downward, and a number of the bristles 53 are fixed on the connecting head 51. An adjusting mechanism is installed on the mounting seat 2. The adjusting mechanism includes an adjusting motor 6, an adjusting screw 7, a supporting nut 8, an adjusting ring 9 and a sliding push rod 10. The adjusting motor 6 is fixed on the mounting seat 2, the adjusting screw 7 is arranged at the output end of the adjusting motor 6, the supporting nut 8 is in sliding fit with the adjusting screw 7, the supporting nut 8 is slidably connected to the brush disk seat 4, the adjusting ring 9 is fixedly connected to the brush disk seat 4, a number of sliding holes are arranged in the circumferential direction of the adjusting ring 9, the sliding push rod 10 is slidably fitted through the sliding holes, a guiding ring 11 is sleeved on the outside of the adjusting ring 9, guiding holes corresponding to the sliding holes are arranged on the guiding ring 11, the sliding push rod 10 is slidably fitted through the guiding holes of the guiding ring 11, one end of the sliding push rod 10 abuts against the side wall of the supporting nut 8, a hinged ring is arranged on the side of the sliding push rod 10 facing away from the supporting nut 8, the hinged ring is sleeved on the connecting rod 52, the inner diameter of the hinged ring is larger than the diameter of the connecting rod 52, a resisting block 12 is arranged on the side of the sliding push rod 10 facing the supporting nut 8, a resisting spring is sleeved on the sliding push rod 10, and both ends of the resisting spring abut between the adjusting ring 9 and the resisting block 12. The supporting nut 8 is integrally formed with a connecting portion 81, an adjusting portion 82 and a limiting portion 83 from top to bottom. The inner side of the connecting portion 81 is in threaded fit with the adjusting screw 7, and the outer side is in sliding fit with the brush disk seat 4. The adjusting portion 82 is set as a frustum shape, and the outer wall is set as a frustum surface. The limiting portion 83 is arranged at the lower end of the adjusting portion 82.

[0025] Further, the adjusting portion 82 is set as a frustum shape with a larger diameter at the lower end than at the upper end.

[0026] Working principle: In the present utility model, by rotating the adjusting motor 6, the supporting nut 8 slides up and down on the adjusting screw 7. The sliding push rod 10 always abuts against the frustum surface of the adjusting portion 82 of the supporting nut 8 under the action of the resisting spring. The up and down sliding of the supporting nut 8 enables the sliding push rod 10 to slide in and out on the adjusting ring 9, so as to make the brush bundle 5 rotate in and out, thereby changing the cleaning angle of the brush bundle 5. By increasing the cleaning radius of the brush bundle, it extends into the dead corner to clean the sundries.

[0027] In addition, the adjusting part 82 is arranged in a frustum shape with a larger diameter at the lower end than at the upper end, so that when the brush bundle expands, the support nut 8 can slide upward to avoid the support nut 8 hitting the ground due to the decrease in the height of the brush bundle caused by the expansion of the brush bundle.

[0028] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
