[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Reference Figures 1 - 3 An embodiment of the present invention is a wall cleaning device for building decoration, comprising a vehicle body 1, four sets of moving wheels are arranged at the bottom end of the vehicle body 1, and a handle is arranged at the rear end. The handle cooperates with the movement of the moving wheels to push the whole to the position where the building decoration wall is to be cleaned. A collection box a2 is fixedly connected to the center of the surface of the vehicle body 1, and a discharge door is arranged on the surface of the collection box a2. By opening the discharge door, the dust generated by the internal decoration can be adsorbed and then processed centrally. A fan 3 is arranged on the outer wall of the bottom end of the collection box a2, and a telescopic hose 4 is fixedly connected to the surface of the fan 3. A dust suction port 5 is fixedly connected to the end of the telescopic hose 4 away from the fan 3, and a filter head 15 is fixedly connected to the surface of the dust suction port 5. The fan 3 is arranged so that suction is generated when it is working, so as to remove dust from the dust suction port 5. The dust generated when cleaning the wall can be sucked into the dust suction port 5 through the filter holes of the filter head 15, and then sucked into the collection box a2 through the telescopic hose 4 for centralized treatment. The surfaces on both sides of the dust suction port 5 are fixedly connected with connecting blocks 10. The inner wall of the connecting block 10 is detachably mounted with a collection box b12 through a quick-release assembly 16. The surface of the collection box b12 is fixedly connected with a cleaning scraper 13. By providing the collection box b12, large pieces of waste scraped off when cleaning the wall can be collected, and the cleaning scraper 13 is tilted upward, so that when the sliding seat 14 moves upward, the wall skin and the like on the wall will be scraped off by the cleaning scraper 13, and the wall skin will fall into the collection box b12 through its surface. A dredging and disassembly mechanism 11 is provided between the two groups of connecting blocks 10.

[0022] Reference Figures 4 - 6, the dredging and disassembling mechanism 11 includes a connecting frame 111. The connecting frame 111 is fixedly connected to the outer side walls of two groups of connecting blocks 10. The connecting frame 111 is formed in a U shape so that it can be fixed to the side walls of the two connecting blocks 10. The outer wall of the scraper 113 is in contact with the surface of the filter head 15. The contact between the two enables the construction waste adsorbed on the surface of the filter head 15 to be scraped and pushed into the interior of the collection box b12 for collection. At the top of the outer wall of the connecting frame 111, an electric telescopic rod 112 is fixedly connected. The telescopic end of the electric telescopic rod 112 is fixedly connected to a scraper 113. By driving the electric telescopic rod 112, the scraper 113 can be lowered to contact the surface of the filter head 15. The inner wall of the scraper 113 is elastically connected to a dredging ball 116 through a return spring 115. One end of the return spring 115 is fixedly connected to the outer wall of the dredging ball 116, and the other end of the return spring 115 is fixedly connected to the inner wall of the scraper 113. The function of the return spring 115 is to automatically reset the position of the spherical surface at the front end of the dredging ball 116 after being squeezed and moved. The dredging ball 116 is slidably connected to the inner wall of the scraper 113. The surface of the filter head 15 is provided with filter holes. The outer wall of the dredging ball 116 is in contact with the inner wall of the filter holes of the filter head 15. The contact between the two enables the dredging ball 116 to dredge the filter holes of the filter head 15 when the scraper 113 descends to clean the surface of the filter head 15, thereby preventing it from being blocked, affecting the adsorption of dust, and causing dust emission. Convex plates 114 are fixedly connected to both side walls of the scraper 113. When the scraper 113 descends, it will drive the two convex plates 114 to descend synchronously.

[0023] Refer to Figure 2 and Figure 3 , a fixed frame 6 is fixedly connected to the surface of the vehicle body 1. A motor 7 is fixedly connected to the top of the fixed frame 6. The output shaft of the motor 7 is fixedly connected to a threaded rod 8. Two groups of guide rods 9 are fixedly connected to the inner side walls of the fixed frame 6. A sliding seat 14 is slidably connected to the surface of the guide rods 9. An internal threaded groove is formed at the center of the sliding seat 14. The sliding seat 14 is threadedly connected to the surface of the threaded rod 8. The threaded rod 8 is rotatably connected to the center of the inside of the fixed frame 6. The outer wall of the sliding seat 14 is fixedly connected to the outer wall of the dust suction port 5. By driving the motor 7, the threaded rod 8 can be rotated circumferentially. At the same time, the sliding seat 14 will move up and down on its surface in a threaded manner and is guided by the two guide rods 9. When the sliding seat 14 moves up and down, it will also drive the dust suction port 5, the collection box b12, and the cleaning scraper 13 to move up and down synchronously, so as to clean the walls of building decoration.

[0024] Refer to Figure 7 and Figure 8, the quick-release component 16 includes T-shaped blocks 161. There are two sets of T-shaped blocks 161, and the two sets of T-shaped blocks 161 are fixedly connected to the surface of the collection box b12. The positioning block 162 is slidably connected to the inner wall of the T-shaped block 161. The inner wall of the T-shaped block 161 is elastically connected to the positioning block 162 through a limiting spring 163. One end of the limiting spring 163 is fixedly connected to the bottom end of the outer wall of the positioning block 162, and the other end of the limiting spring 163 is fixedly connected to the bottom end of the inner wall of the T-shaped block 161. The function of the limiting spring 163 is to automatically reset the position of the positioning block 162 after it is pressed down, and at the same time, it also exerts elastic support on the position of the positioning block 162. A guide groove is provided on the inner side of the connecting block 10, and the outer wall of the T-shaped block 161 is in contact with the inner wall of the guide groove. By providing the T-shaped block 161, when installing the collection box b12, the T-shaped block 161 can be aligned with the T-shaped groove at the bottom end of the connecting block 10, so as to position and install the collection box b12. The outer wall of the positioning block 162 is in contact with the inner wall of the guide groove of the connecting block 10. The contact between the two enables the T-shaped block 161 to first press down the positioning block 162 when installed until the positioning block 162 is flush with the guide groove at the upper end of the connecting block 10, and insert the T-shaped block 161 into the T-shaped groove at the lower end of the connecting block 10. When the installation is in place, the positioning block 162 will be automatically reset under the elastic action of the limiting spring 163, so as to position the position of the T-shaped block 161 and the collection box b12 after installation. The top end of the positioning block 162 is in contact with the bottom end of the convex plate 114. By providing the convex plate 114, when the scraping plate 113 descends to dredge the surface of the filter head 15, it will also push the positioning block 162 to descend in the inner wall of the T-shaped block 161, so as to push the positioning block 162 to move to the straight groove at the upper end of the connecting block 10, so that the T-shaped block 161 and the collection box b12 can be disassembled and installed.

[0025] Working principle: After starting the fan 3, it generates negative pressure suction, which is conducted to the dust suction port 5 through the telescopic hose 4. The filter head 15 at the front end of the dust suction port 5 captures the dust particles generated by wall cleaning through the filter holes. The dust penetrates the filter holes under the action of suction, and passes through the dust suction port 5 and the telescopic hose 4 in turn, and finally enters the collection box a2 for internal storage. When the dust collection amount in the collection box a2 reaches the processing requirement, opening the discharge door can complete the centralized cleaning of the dust.

[0026] The motor 7 is fixed to the top of the fixed frame 6, and its output shaft drives the threaded rod 8 to rotate. The sliding seat 14 is engaged with the threaded rod 8 through the internal thread groove and is provided with guiding constraints by the guide rods 9 on both sides. When the threaded rod 8 rotates, the sliding seat 14 moves linearly up and down along the guide rod 9. Since the sliding seat 14 is fixedly connected to the dust suction port 5, it drives the dust suction port 5, the collection box b12, and the cleaning scraper 13 to lift and lower synchronously. The cleaning scraper 13 that is inclined upward, during the upward movement driven by the sliding seat 14, scrapes off large waste materials such as wall skins and paint debris attached to the wall surface by virtue of the inclined edge, and the scraped waste materials slide down into the interior of the collection box b12 for temporary storage, realizing the efficient collection of waste materials.

[0027] When the electric telescopic rod 112 is started to lower the scraper 113, the outer wall of the scraper 113 fits the surface of the filter head 15, scrapes off the waste materials attached to the surface of the filter head 15 and pushes them into the collection box b12. At the same time, the dredging ball 116 on the inner wall of the scraper 113 closely cooperates with the filter holes of the filter head 15. During the downward movement of the scraper 113, the dredging ball 116 is elastically acted on by the return spring 115 to reciprocally dredge the filter holes. When the blockage in the filter hole squeezes the dredging ball 116, the return spring 115 is compressed and deformed; after the blockage is removed, the spring returns to push the dredging ball 116 back to its original position, continuously ensuring the smoothness of the filter holes and maintaining the high-efficiency dust suction performance.

[0028] When installing the collection box b12, press the positioning block 162 to make it descend against the elastic force of the limit spring 163, and accurately insert the T-shaped block 161 into the T-shaped groove at the bottom of the connecting block 10. When the T-shaped block 161 is installed in place, the positioning block 162 automatically pops out under the action of the limit spring 163 and snaps into the guide groove of the connecting block 10 for positioning and fixing. When disassembling, during the downward movement of the scraper 113, the convex plates 114 on both sides of it press down the positioning block 162 to make it retract into the T-shaped block 161, releasing the lock on the collection box b12, and then the collection box b12 can be easily disassembled, facilitating subsequent cleaning and maintenance.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
