Abstract
Description
Technical Field
[0001] This invention relates to the field of building engineering technology, and specifically to a building wall cleaning device. Background Technology
[0002] Over time, the surfaces of building interior and exterior walls may develop problems such as surface peeling, holes, and mold, leading to cracks in the wall surface, reduced wall strength and aesthetics, and even threats to personal safety and property. Therefore, wall repair is necessary. Current technology mainly involves setting up scaffolds and using manual methods to scrape and polish the coating on the building wall surface and spray a new coating.
[0003] However, in the long-term process of repairing interior and exterior walls of buildings, it has been found that existing technologies still have certain drawbacks: First, building walls are not all flat surfaces. Walls with some protrusions or concave structures are often encountered. Relying on operational experience to grind the wall can lead to incomplete cleaning of protrusions or concave structures due to different operating angles of the cleaning device. Second, for interior walls, the bottom of the wall is often equipped with a marble skirting board area. The cleaning discs commonly used in existing technologies are inconvenient to operate within the radius of the corner in this area, resulting in incomplete coating on the wall surface and easy breakage of the skirting board. Summary of the Invention
[0004] The purpose of this invention is to provide a building wall cleaning device to solve the above-mentioned defects caused by the prior art.
[0005] A building wall cleaning device includes a base frame, a mounting base, an adjustment mechanism, and a cleaning mechanism. The base frame is handheld and the adjustment mechanism is mounted on it. The mounting base is movably mounted on the base frame and is used to clean and adjust building walls according to different tilt angles. The cleaning mechanism is mounted on the mounting base and is used for general cleaning of building walls.
[0006] Preferably, the adjustment mechanism includes a handle, a threaded rod, and a slider. The threaded rod is threadedly mounted on the base frame, the handle is fixedly connected to the end of the threaded rod, the slider is rotatably mounted on the other end of the threaded rod, and the slider is also slidably mounted on the base frame. A connecting rod is hinged to the side end of the slider, and the other end of the connecting rod is hinged to the mounting base.
[0007] Preferably, the cleaning mechanism includes a drive motor, a cleaning disc, and a scraper. The drive motor is mounted on a mounting base, and a rotating seat is mounted on the output end of the drive motor. Two symmetrically arranged planetary gears are mounted on both ends of the rotating seat. A crank is fixedly mounted on the other end of each planetary gear. A sliding seat is provided inside the crank via a spring. The cleaning disc is fixedly mounted on the sliding seat. A positioning frame is also fixedly mounted on the mounting base. The side ends of the two planetary gears abut against the inner wall of the positioning frame. A drive wheel is also mounted on the output shaft of the drive motor. A driven wheel is mounted on the other side of the positioning frame. The driven wheel is connected to the drive wheel via a synchronous belt. A crank is fixedly connected to the other side of the driven wheel. A slider is rotatably mounted at the end of the crank. A swinging component is also mounted on the positioning frame. The slider is slidably disposed on one side of the swinging component. The scraper is adjustablely mounted on the other side of the swinging component via a blade holder.
[0008] Preferably, when the swinging member is placed in a horizontal state, the cutting edge of the scraper is coplanar with the working surface of the cleaning disc.
[0009] Preferably, the swing member is also provided with a vacuum cleaner mounting groove.
[0010] Preferably, there is no contact between the positioning frame and the timing belt.
[0011] The advantages of this invention are:
[0012] By setting an adjustment mechanism on the base frame and a cleaning mechanism on the mounting base, the operating angle of the mounting base is adjusted by the handle, and the drive motor drives the rotating base and the drive wheel to rotate synchronously. This causes the two cleaning discs to rotate alternately, while the scraper also swings back and forth with the swinging component. When encountering uneven building walls, the two alternately rotating cleaning discs clean the wall surface with protruding or concave structures, while the scraper, after adjusting its extension position, cleans the wall surface without protruding or concave structures. The vacuum cleaner in the vacuum cleaner mounting slot sucks up the cleaned dust, ensuring complete and consistent cleaning of uneven building walls.
[0013] When cleaning flat interior walls, select an extended scraper and install it horizontally. When the cleaning disc touches the baseboard area, the spring will cause it to move towards the center of the positioning frame, allowing for further scraping with the scraper to completely clean the wall surface coating. This also prevents the baseboard from breaking during the cleaning process. Attached Figure Description

Detailed Implementation
[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0021] like Figures 1 to 5 As shown, a building wall cleaning device includes a base frame 1, a mounting base 2, an adjustment mechanism 3, and a cleaning mechanism 4. The base frame 1 is handheld and the adjustment mechanism 3 is mounted on it. The mounting base 2 is movably mounted on the base frame 1 and is used to clean and adjust building walls according to different tilt angles. The cleaning mechanism 4 is mounted on the mounting base 2 and is used for general cleaning of building walls.
[0022] In this embodiment, the adjustment mechanism 3 includes a handle 31, a threaded rod 32, and a slider 33. The threaded rod 32 is threadedly mounted on the base frame 1, the handle 31 is fixedly connected to the end of the threaded rod 32, the slider 33 is rotatably mounted on the other end of the threaded rod 32, and the slider 33 is also slidably mounted on the base frame 1. A connecting rod 34 is hinged to the side end of the slider 33, and the other end of the connecting rod 34 is hinged to the mounting base 2.
[0023] In this embodiment, the cleaning mechanism 4 includes a drive motor 401, a cleaning disc 402, and a scraper 403. The drive motor 401 is mounted on the mounting base 2. A rotating seat 404 is mounted on the output end of the drive motor 401. Two symmetrically arranged planetary gears 405 are mounted on both ends of the rotating seat 404. A crank handle 406 is fixedly mounted on the other end of the planetary gears 405. A sliding seat 408 is provided inside the crank handle 406 via a spring 407. The cleaning disc 402 is fixedly mounted on the sliding seat 408. A positioning frame 409 is also fixedly mounted on the mounting base 2. The two planetary gears 401, 402, and 403 are mounted on the mounting base 2. The side end of 05 abuts against the inner wall of the positioning frame 409. The output shaft of the drive motor 401 is also equipped with a drive wheel 410. The other side of the positioning frame 409 is equipped with a driven wheel 411. The driven wheel 411 is connected to the drive wheel 410 through a synchronous belt 412. The other side of the driven wheel 411 is fixedly connected with a crank 413. The end of the crank 413 is rotatably equipped with a slider 414. The positioning frame 409 is also equipped with a swing member 415. The slider 414 is slidably disposed on one side of the swing member 415. The scraper 403 is adjustablely mounted on the other side of the swing member 415 through a blade holder 416.
[0024] It should be noted that when the swing member 415 is placed in a horizontal state, the cutting edge of the scraper 403 is coplanar with the working surface of the cleaning disc 402.
[0025] In this embodiment, the swing member 415 is also provided with a vacuum cleaner mounting groove 417.
[0026] Furthermore, there is no contact between the positioning frame 409 and the timing belt 412.
[0027] Working process and principle: In the process of using this invention, the operator first manually rotates the handle 31, which drives the slider 33 to slide within 1 via the threaded rod 32. The operating angle of the mounting base 2 is adjusted according to the actual state of the building wall by the push and pull action of the connecting rod 34. The installation position of the knife holder 416 is adjusted by tightening and loosening the bolts on the swing member 415. Then, the drive motor 401 is started, which drives the rotating base 404 to rotate at its output end. During the rotation of the rotating base 404, under the guidance of the positioning frame 409, the two symmetrical planetary gears 405 rotate alternately in the same direction along the inner wall of the positioning frame 409. Then, the sliding seat 408 in the crank 406 drives the cleaning disc 402 to rotate alternately.
[0028] At the same time, the output shaft of the drive motor 401 also drives the drive wheel 410 to rotate. The rotation of the drive wheel 410 drives the crank 413 to rotate at the lower part of the positioning frame 409 via the synchronous belt 412 and the driven wheel 411. Then, it slides back and forth on the swing member 415 with the side arc shape through the slider 414, driving the scraper 403 to swing back and forth with the swing member 415.
[0029] When encountering uneven building walls, two staggered rotating cleaning discs 402 are used to smooth and clean the wall surface with protruding or concave structures, while the scraper 403 with its extended position adjusted is used to smooth and clean the wall surface without protruding or concave structures. The vacuum cleaner in the vacuum cleaner mounting slot 417 sucks up the cleaned dust, ensuring that the cleaning of uneven building walls is complete and consistent.
[0030] When cleaning a flat building wall, the scraper 403 first scrapes away the convex coating, and then two staggered rotating cleaning discs 402 further smooth the wall after the initial scraping. The wall cleaning operation is completed by combining swing scraping and rotation scraping, which saves effort and ensures a more complete cleaning of the wall surface. For interior walls, when cleaning the baseboard area, an extended scraper 403 is selected and installed. The device is then used in a horizontal position. When the cleaning disc 402 touches the baseboard area, the spring 407 will cause the cleaning disc 402 to buffer towards the center of the positioning frame 409. With the further scraping of the scraper 403, the wall surface coating is completely cleaned, and the baseboard is prevented from breaking during the cleaning process.
[0031] Based on the above, the present invention provides an adjustment mechanism 3 on the base frame 1 and a cleaning mechanism 4 on the mounting base 2. The operating angle of the mounting base 2 is adjusted by the handle 31, and the drive motor 401 drives the rotating base 404 and the drive wheel 410 to rotate synchronously. This causes the two cleaning discs 402 to rotate alternately while the scraper 403 swings back and forth with the swinging component 415. When encountering uneven building walls, the two alternately rotating cleaning discs 402 clean the wall surface with protrusions or concave structures, and the scraper 403, after adjusting its extension position, cleans the wall surface without protrusions or concave structures. The vacuum cleaner in the vacuum cleaner mounting slot 417 sucks out the cleaned dust, ensuring complete and consistent cleaning of uneven building walls.
[0032] When cleaning flat interior walls, an extended scraper 403 is installed. The device is then used in a horizontal position for cleaning. When the cleaning disc 402 touches the baseboard area, the spring 407 causes the cleaning disc 402 to move towards the center of the positioning frame 409, which, combined with the subsequent scraping by the scraper 403, completely cleans the coating on the wall surface and prevents the baseboard from breaking during the cleaning process.
[0033] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
