Description

Technical Field

[0001] This invention relates to the field of wall decoration technology, specifically to a wall cleaning device for interior decoration. Background Technology

[0002] Wall decoration is an integral part of architectural design. Modern interior walls utilize variations in color and texture to beautify the interior environment and regulate lighting. Various materials with easy cleaning and good physical properties are selected to meet multiple functional requirements and enhance the quality of living and the sensory experience of the home.

[0003] However, existing wall cleaning devices for interior decoration and renovation on the market have overly simple structures, limited functions, low performance, poor adaptability due to lack of structural deformation capabilities, require manual operation at heights, are highly dangerous, and involve a large amount of manual labor.

[0004] As disclosed in CN213449346U, a wall cleaning device for interior decoration and renovation uses a battery and power cord to easily move the device to the corresponding working position, simplifying the operation process. A fixed sleeve, fixed ring, and threaded head allow for the extension rod to be extended to adapt to different working heights, reducing additional preparation work. A grinding head, connected to a connector, rotates at high speed under the drive of the grinding box, making it easy to replace the grinding head and perform simple polishing of the wall surface for subsequent operations. A compression spring and guide rail facilitate easy replacement of the scraper blades, enabling multi-layer scraping of the work surface and ensuring its smoothness. A fixed plate and pressure plate fix the scraper blades at a fixed angle, making them easy to disassemble and replace. Multiple sets of scraper blades increase the number of scraping operations, allowing for multiple cleanings of the work surface with good cleaning quality.

[0005] However, the device requires staff to manually clean the wall by holding the lower rod, which is labor-intensive and has low cleaning efficiency.

[0006] Therefore, we urgently need to provide a wall cleaning device for interior decoration and renovation. Summary of the Invention

[0007] The purpose of this invention is to provide a wall cleaning device for interior decoration and renovation, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a wall cleaning device for interior decoration, comprising a base plate, wherein a cleaning device is provided on the top of the base plate, and the cleaning device includes an adjustment unit, a cleaning unit, a spraying unit, and a disassembly unit.

[0009] The adjustment unit is located above the base plate, the cleaning unit is located above the base plate, the spraying unit is located on top of the base plate, and the disassembly unit is located above the base plate.

[0010] The adjustment unit includes casters, a vertical plate, a first motor, a threaded rod, a slider, a housing, a second motor, a drive shaft, a driven shaft, and a box. The casters are fixedly installed around the bottom of the base plate. The vertical plate is fixedly installed on the top of the base plate. The first motor is fixedly installed on the bottom of the base plate. The threaded rod is fixedly installed at the output end of the first motor. The slider is slidably connected inside the vertical plate. The housing is located inside the slider. The second motor is fixedly installed on the left side of the slider. One end of the drive shaft is fixedly installed at the output end of the second motor, and the other end is fixedly connected to the left side of the housing. One end of the driven shaft is rotatably connected inside the slider, and the other end is fixedly connected to the right side of the housing. The box is fixedly installed on the front of the housing.

[0011] Preferably, the upright plate has a groove inside, the slider is slidably connected inside the upright plate, and the slider has an internal thread. The threaded rod passes through the slider and is threadedly connected to the slider. By starting the motor, the threaded rod is driven to rotate and is threadedly connected to the slider, so that the slider slides up and down along the groove, and the cleaning brush moves up and down to clean different parts of the wall.

[0012] Preferably, the cleaning unit includes a third motor, a rotating shaft, a first gear, a connecting shaft, a second gear, a cleaning brush, and a mounting shaft. The third motor is fixedly installed inside the housing. The rotating shaft is fixedly installed at the output end of the third motor. The first gear is fixedly installed on the outside of the rotating shaft. The connecting shaft is rotatably connected to the left and right sides inside the housing and extends to the outside of the housing at one end. The second gear is fixedly installed on the outside of the two connecting shafts on the left and right sides. The cleaning brush is disposed on the left and right sides of the front of the housing. The mounting shaft is fixedly installed on the back of the cleaning brush.

[0013] Preferably, the connecting shaft has an internal mounting hole, the diameter of the mounting shaft is equal to the diameter of the mounting hole, and the mounting shaft is inserted into the connecting shaft, so that the cleaning brush can be mounted on the connecting shaft through the mounting shaft.

[0014] Preferably, the spraying unit includes a water tank, a pump body, a water outlet pipe, a connecting pipe, and a nozzle. The water tank is installed on the top left side of the base plate, the pump body is installed on the top of the water tank, the water outlet pipe is connected to the top of the pump body, the connecting pipe is fixedly installed inside the housing, and the nozzle is connected to the left and right sides of the front of the connecting pipe.

[0015] Preferably, the end of the water outlet pipe furthest from the pump body is connected to the connecting pipe, which is made of stainless steel. When the cleaning brush cleans the wall, the pump body is activated to draw cold water from the water tank into the water outlet pipe, which is then sprayed out from the nozzle through the connecting pipe. At the same time, as the cold water flows along the connecting pipe, it exchanges heat with the heat generated by the meshing of gear one and gear two, thereby cooling gear one and gear two and improving their service life.

[0016] Preferably, the disassembly and assembly unit includes a mounting block, a spring, a baffle, a locking rod, and a pull rod. The mounting block is fixedly installed on the top of the left and right connecting shafts, the spring is fixedly installed inside the top of the mounting block, the baffle is fixedly installed on the bottom of the spring, the locking rod is fixedly installed on the bottom of the baffle, and the pull rod is fixedly installed on the top of the baffle and extends above the mounting block.

[0017] Preferably, the outer surface of the connecting shaft is provided with a positioning hole, and the outer surface of the mounting shaft is provided with a locking hole. The diameter of the locking rod is equal to the diameter of the positioning hole and the locking hole. After the mounting shaft is inserted into the connecting shaft, the locking rod engages with the positioning hole and the locking hole to fix the mounting shaft, thereby fixing the cleaning brush on the connecting shaft.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. This interior decoration wall cleaning device, through the setting of an adjustment unit, pushes the base plate and uses universal wheels to move the device to the desired position. Starting motor one drives the threaded rod to rotate, which is threadedly connected to the slider, causing the slider to move the housing up and down to clean different parts of the wall. When cleaning the ceiling is required, the slider is moved to the top of the vertical plate, and then motor two is started to drive the drive shaft to rotate. The rotation of the drive shaft causes the housing to rotate, causing the cleaning brush to rotate upwards by 90 degrees. The ceiling can then be cleaned using the cleaning brush. This eliminates the need for workers to hold the device while cleaning the walls, reducing labor intensity and improving work efficiency. It solves the problem in the background technology where workers need to hold the lower rod to clean the walls, resulting in high labor intensity and low cleaning efficiency.

[0019] 2. This interior decoration wall cleaning device, by setting up a spray unit, draws cold water from the water tank into the outlet pipe and sprays it out from the nozzle during cleaning. This cleans the wall while reducing dust generated during cleaning. As the cold water flows along the connecting pipe, it exchanges heat with the gears 1 and 2, thereby cooling the gears 1 and 2 and extending their service life.

[0020] 3. This interior decoration wall cleaning device, through the setting of a disassembly and assembly unit, allows for easy replacement of the cleaning brush when it is damaged and needs to be replaced. Pulling the lever upwards moves the baffle and locking rod upwards, causing the locking rod to disengage from the locking hole opened on the mounting shaft. Then, the cleaning brush is pulled out, and a new cleaning brush is inserted into the connecting shaft and locked in place by the locking rod, thus completing the replacement of the cleaning brush.

The rotating shaft 302 drives gear 1 303 to rotate. When gear 1 303 rotates, it meshes with the two gears 2 305 on the left and right sides, so that the two gears 2 305 drive the connecting shaft 304 to rotate. When the connecting shaft 304 rotates, the mounting shaft 307 drives the cleaning brush 306 to rotate to clean the wall. The cleaning brush 306 is set on the left and right sides of the front of the box 210. The mounting shaft 307 is fixedly installed on the back of the cleaning brush 306.

[0030] The spray unit includes a water tank 401, a pump body 402, a water outlet pipe 403, a connecting pipe 404, and a nozzle 405. The water tank 401 is installed on the top left side of the base plate 1, the pump body 402 is installed on top of the water tank 401, and the water outlet pipe 403 is connected to the top of the pump body 402. The end of the water outlet pipe 403 away from the pump body 402 is connected to the connecting pipe 404, which is made of stainless steel. When the cleaning brush 306 cleans the wall, the pump body 402 is activated to spray water from the water tank 401. Cold water is drawn into the outlet pipe 403 and sprayed out through the nozzle 405 via the connecting pipe 404. At the same time, as the cold water flows along the connecting pipe 404, it exchanges heat with the heat generated by the meshing of gear 1 303 and gear 2 305, thereby cooling gear 1 303 and gear 2 305 and improving their service life. The connecting pipe 404 is fixedly installed inside the box 210, and the nozzle 405 is connected to the left and right sides of the front of the connecting pipe 404.

[0031] The assembly / disassembly unit includes a mounting block 501, a spring 502, a baffle 503, a locking rod 504, and a pull rod 505.

The baffle 503 is fixedly installed on the bottom of the spring 502. The locking rod 504 is fixedly installed on the bottom of the baffle 503. The connecting shaft 304 has a positioning hole on its outer surface, and the mounting shaft 307 has a locking hole on its outer surface. The diameter of the locking rod 504 is equal to the diameter of the positioning hole and the locking hole. After the mounting shaft 307 is inserted into the connecting shaft 304, the locking rod 504 engages with the positioning hole and the locking hole to fix the mounting shaft 307, thereby fixing the cleaning brush 306 to the connecting shaft 304. The pull rod 505 is fixedly installed on the top of the baffle 503 and extends above the mounting block 501.

[0032] In use, push the base plate 1 with the casters 201 to move the device to the desired position and bring the cleaning brush 306 into contact with the wall to be cleaned. Then, start the motor 301 to drive the rotating shaft 302 to rotate. The rotating shaft 302 drives the gear 1 303 to rotate. When the gear 1 303 rotates, it meshes with the two gears 305 on the left and right, thereby causing the two gears 305 to drive the connecting shaft 304 to rotate. When the connecting shaft 304 rotates, it drives the cleaning brush 306 to rotate through the mounting shaft 307 to clean the wall. At the same time, start the motor 203 to drive the threaded rod 204 to rotate and connect it to the slider 205. This causes the slider 205 to move the housing 210 up and down to clean different parts of the wall. When it is necessary to clean the ceiling, move the slider 205 to the top of the upright plate 202, and then start the motor 207 to drive the drive shaft 208 to rotate. When the drive shaft 208 rotates, it drives the housing 206 to rotate, thus cleaning the ceiling. The cleaning brush 306 is rotated upwards by 90 degrees, and then the ceiling can be cleaned using the cleaning brush 306. During cleaning, the pump body 402 is started to draw cold water from the water tank 401 into the water outlet pipe 403, which is then sprayed out from the nozzle 405 through the connecting pipe 404 to clean the walls and reduce dust generated during cleaning. As the cold water flows along the connecting pipe 404, it exchanges heat with the gears 303 and 305, thereby cooling the gears 303 and 305 and extending their service life. When the cleaning brush 306 is damaged and needs to be replaced, the pull rod 505 is pulled upwards to move the baffle 503 and the locking rod 504 upwards, causing the locking rod 504 to disengage from the locking hole in the mounting shaft 307. Then the cleaning brush 306 is pulled out, and a new cleaning brush 306 is inserted into the connecting shaft 304 and locked in place by the locking rod 504, thus completing the replacement of the cleaning brush 306.
