[0002] In the home environment, dust and spider webs are easily accumulated in the corners of the ceiling, and in the past, they had to be cleaned with the help of ladders, brooms and other tools. The cleaning process is highly dangerous, inefficient and labor-intensive. Small commercial places, such as shops and offices, have large ceiling areas, and manual cleaning is time-consuming and labor-intensive.

[0003] Chinese patent announcement number CN217471898U discloses a ceiling cleaning device for a building, which belongs to the technical field of building technology.

When the length of the cleaning wipe needs to be adjusted, the rotating roller can be rotated. At this time, the power can be transmitted to the screw through the transmission of the screw nut and two I-shaped wheels. At this time, the screw nut will rise and drive the thin insertion rod to rise, thereby changing the height of the thick sleeve and the thin insertion rod, thereby changing the height of the cleaning wipe to adapt to the height of different ceilings, thereby improving the convenience and thoroughness of cleaning of the device.

[0038] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0039] Reference Figure 1 The preferred embodiment of the present invention provides a cleaning device for the ceiling of a building, comprising: an installation box 1 that is supported on the ground by rolling, a lifting drive mechanism 4, a mounting seat 2 fixed to the top of the lifting drive mechanism 4, and a dust scraping and compacting device fixed in the mounting seat 2. The main structure of the lifting drive mechanism 4 is arranged in the installation box 1, and the lifting drive structure of the lifting drive mechanism 4 vertically extends upward from the installation box 1 to connect with the mounting seat 2. The dust scraping and compacting device comprises a cleaning mechanism 5 for scraping and cleaning the ceiling, a collecting box 6 for collecting scraped dust, a storage box 7 for storing the collected dust, and a compacting mechanism 8 for compacting the dust stored in the storage box 7. The collection box 6 is connected to the storage box 7, and the compacting mechanism 8 is connected to the cleaning mechanism 5 for synchronous operation.

[0040] The cleaning device of the present invention includes a lifting drive mechanism 4, which is used to assist the mounting seat 2 and the dust scraping and compacting device to move upward, and there is no need for personnel to climb or manually extend the cleaning device to the ceiling position, thereby reducing the labor of personnel, and the installation box 1 supported on the ground can be easily moved to various positions to comprehensively clean all corners of the ceiling; the cleaning device of the present invention also includes a cleaning mechanism 5, a collecting box 6, a storage box 7 and a compacting mechanism 8. When working, the ceiling can be scraped and cleaned by the cleaning mechanism 5, and the scraped dust can be uniformly collected and stored by the collecting box 6 and the storage box 7, and the dust scraping During the dust removal and collection, the cleaning mechanism 5 drives the compacting mechanism 8 to act synchronously, so as to gradually compact the dust stored in the storage box 7, thereby avoiding the dust overflowing when the collected dust is subsequently cleaned; at the same time, the device of the present invention can greatly improve the cleaning efficiency and reduce the time cost of cleaning. Whether it is a ceiling made of wood, plaster or other materials, it can clean safely and effectively without damaging the surface of the ceiling. In addition, in some simple buildings built in temporary activity venues, it can also quickly clean the ceiling, creating a clean environment for the smooth development of activities, and meeting the needs of ceiling cleaning in different scenarios.

[0041] Alternatively, if Figure 3 and Figure 4As shown, the collection box 6 is a hollow box with openings at both the upper and lower ends. The cleaning mechanism 5 is connected to the upper opening end of the collection box 6, and the compaction mechanism 8 is connected to the lower opening end of the collection box 6. The storage box 7 is connected to the bottom end of the collection box 6 and is in communication with the lower opening end of the collection box 6, so that the dust collected by the collection box 6 can fall into the storage box 7, and it is also convenient for the compaction mechanism 8 provided at the lower opening end of the collection box 6 to move down into the storage box 7 to compact the stored dust, and the storage box 7 is also connected to the mounting base 2.

[0042] In this alternative solution, as Figure 3 shown, mounting holes 601 penetrating the plate surfaces are correspondingly provided on the two side plates at the upper opening end of the collection box 6. Combining with Figure 5 shown, the cleaning mechanism 5 includes two turntables 51 rotatably installed in the two mounting holes 601, a cleaning roller 52 for scraping the ceiling, a support platform 53 connected to the outer wall surface of one of the side plates of the collection box 6, and a first drive motor 54 fixed to the support platform 53. The cleaning roller 52 is arranged in the upper opening of the collection box 6 along the width direction of the collection box 6, and both ends of the cleaning roller 52 are respectively fixedly connected to the corresponding turntable 51 on the corresponding side. The output end of the first drive motor 54 is fixed to the corresponding turntable 51.

[0043] During operation, when the height to be cleaned is adjusted by the lifting drive mechanism 4, the first drive motor 54 can be started, so that the output end of the first drive motor 54 drives the turntable 51 fixedly connected thereto to rotate through a coupling. When the turntable 51 rotates, since one end of the two turntables 51 close to each other is fixedly connected to the cleaning roller 52 together, and the turntables 51 on both sides are respectively slidably connected to the inner surface of the corresponding mounting hole 601, when one of the turntables 51 rotates, the cleaning roller 52 also rotates accordingly. In the design, a brush is fixedly connected to the outer surface of the cleaning roller 52, so that the brush fixedly connected to its surface can clean the ceiling during the rotation of the cleaning roller 52, and during the cleaning process, the dust will fall downward from the opening of the collection box 6 into the inner cavity of the storage box 7 for collection.

[0044] Optionally, as Figure 4 and Figure 5As shown, the compacting mechanism 8 includes two groups of belt transmission components 81 respectively connected to the two rotating disks 51, two groups of reciprocating components 82 respectively connected to the two groups of belt transmission components 81, and a pressing plate 83 for compacting dust. The two groups of belt transmission components 81 are located in the collection box 6, and are used to rotate under the drive of the rotating disk 51. The two groups of reciprocating components 82 are located outside the collection box 6, and the pressing plate 83 is arranged in the lower open end of the collection box 6 along the width direction of the collection box 6. The two groups of reciprocating components 82 are respectively passed through the side plates of the collection box 6 and connected to the two ends of the pressing plate 83. The two groups of reciprocating components 82 are used to reciprocate up and down under the action of the two groups of belt transmission components 81, thereby driving the pressing plate 83 to reciprocate up and down, so as to reciprocate and compact the dust stored in the storage box 7.

[0045] In this option, if Figure 5 As shown, each belt transmission member 81 includes a first pulley 811 fixed on the outer circumference of the rotating disk 51 on the corresponding side, a second pulley 812 rotatably connected to the side plate on the corresponding side of the collecting box 6, and a belt 813 wound around the outer circumference of the first pulley 811 and the second pulley 812. During operation, during a long cleaning process, the outer surfaces of the first pulley 811 and the second pulley 812 on the same side are both connected by the belt 813, so when the rotating disk 51 rotates, the first pulley 811 can be driven to rotate synchronously, and when the first pulley 811 rotates, the second pulley 812 can be driven to rotate at the same time.

[0046] In this option, if Figure 5 and Figure 7 As shown, the reciprocating member 82 includes a disk 821 fixed to the second pulley 812 on the corresponding side, a driving rod 822 eccentrically hinged to the disk 821 at one end, a sliding plate 823 hinged to the other end of the driving rod 822, two first guide plates 824 fixed to the outer wall of the side plate on the corresponding side of the collecting box 6 and arranged relatively spaced apart, and a fixing block 825 fixed to the inner side of the sliding plate 823. The two ends of the sliding plate 823 are respectively slidably connected to the two first guide plates 824. The two fixing blocks 825 are respectively passed through the side plates on the corresponding sides of the collecting box 6 and fixedly connected to the pressing plate 83.

[0047] During operation, while the second pulleys 812 on both sides are rotating, the discs 821 fixedly connected to their outer surfaces also rotate accordingly. Since the driving rods 822 rotatably connected to the discs 821 are located at positions deviating from the center of the circle, and the other ends are rotatably connected to the sliding plates 823, when the discs 821 rotate, the sliding plates 823 can be driven to reciprocate up and down through the driving rods 822, and the two first guide plates 824 on the same side play a role of limiting and guiding. When the sliding plates 823 on both sides reciprocate up and down, fixed blocks 825 are fixedly connected to the mutually approaching ends thereof, and a pressing plate 83 is fixedly connected to the mutually approaching ends of the two fixed blocks 825, so that the pressing plate 83 also reciprocates up and down accordingly. When a certain amount of dust is collected, when the lower end of the pressing plate 83 moves into the storage box 7, the dust can be compacted, and this process is repeated to achieve tight compaction of the dust.

[0048] Preferably, as Figure 3 shown, rectangular grooves 602 penetrating the plate surfaces and extending in the height direction are also formed at the bottoms of the two side plates of the collection box 6, and the two fixed blocks 825 respectively pass through the corresponding rectangular grooves 602 and are fixedly connected to the pressing plate 83. As Figure 7 shown, when the sliding plates 823 on both sides reciprocate up and down, to prevent dust from leaking out of the rectangular grooves 602 on both sides, in the preferred embodiment of the present invention, each reciprocating member 82 further includes an upper blocking plate 826 and a lower blocking plate for blocking the rectangular grooves 602 to prevent dust leakage. The upper blocking plate 826 and the lower blocking plate are respectively vertically connected to the upper and lower sides of the sliding plate 823. By fixedly connecting the upper blocking plate 826 and the lower blocking plate to the upper and lower ends of the sliding plates 823 on both sides respectively, the upper blocking plate 826 and the lower blocking plate always keep the rectangular grooves 602 in a closed state.

[0049] Furthermore, as Figure 7 shown, to prevent the upper blocking plate 826 on the upper side from affecting the operation of other structures during movement, in the preferred embodiment of the present invention, each reciprocating member 82 further includes an avoidance structure for avoiding other structures during the movement of the reciprocating member 82. The avoidance structure includes a mounting groove 8271 formed by inwards concave extension from the top end of the upper blocking plate 826, a top plate 8272 slidably mounted at the lower end in the mounting groove 8271, a guiding column 8273 fixed to the bottom end of the top plate 8272, and a spring 8274 sleeved on the outer circle of the guiding column 8273. The bottom end of the guiding column 8273 slides downwards from the bottom of the mounting groove 8271 and inserts into the upper blocking plate 826. The two ends of the spring 8274 are respectively connected to the bottom plate of the mounting groove 8271 and the top plate 8272. During operation, when the top plate 8272 contacts other structures, it contracts towards the inner cavity of the mounting groove 8271 on the same side, and then compresses the spring 8274, and the guiding column 8273 on the same side slides in the sliding plate on the same side. If not squeezed, it always remains in the initial state.

[0050] Optionally, as Figure 6 shown, the storage box 7 includes a box frame 71 fixed to the bottom end of the collection box 6, and a box body slidably installed in the box frame 71 in a pull-out manner. The box frame 71 is also fixed in the mounting seat 2, and the top surface of the box frame 71 is open for the compaction mechanism 8 to enter and exit. Two guide rails 73 for guiding are also provided in the box frame 71. The box body includes a box main body 721 with openings on both sides, two sliding plates 722 fixed to the upper side of the box main body 721, a partition plate 723 closing the outer end of the box main body 721, and a pull ring 724 fixed to the partition plate 723. The box body is slidably installed in the box frame 71 through the cooperation of its upper sliding plates 722 and the guide rails 73.

[0051] During operation, when the cleaning of the ceiling is completed, after simply starting the lifting drive mechanism 4 to lower the mounting seat 2 and restore it to the initial position, by pulling the pull ring 724, the partition plate 723 is driven to pull out the box main body 721 from the box frame 71. The two sliding plates 722 fixedly connected to the upper end of the box main body 721 cooperate with the two guide rails 73 provided in the box frame 71, so as to play a role of limiting and guiding. Finally, after the box main body 721 is taken out, the collected and compacted dust can be poured out. Preferably, as Figure 6 shown, in order to avoid the lower baffle hitting the partition plate 723 when moving, in this solution, an anti-collision groove 7230 is provided on the inner side of the partition plate 723, thereby avoiding the situation that the lower baffle hits the partition plate 723 when moving. In the dust scraping and compaction device of the present invention, through the provided compaction mechanism 8, after the dust is collected, the collected dust can also be compacted. And when the device for storing dust needs to be taken out subsequently, through the setting of the storage box 7, the operation steps for taking out the dust are simple and convenient, thereby effectively improving the subsequent cleaning efficiency.

[0052] Optionally, as Figure 2 shown, the lifting drive mechanism 4 includes a second drive motor 41 fixed in the installation box 1, a transmission mechanism 42 connected to the output end of the second drive motor 41, and a guide frame fixedly supported on the top end of the installation box 1. The power output end of the transmission mechanism 42 passes through the installation box and the guide frame and then connects to the mounting seat 2 to drive the mounting seat 2 to move up and down. In this optional solution, through the provided lifting drive mechanism 4, the mounting seat 2 and the dust scraping and compaction device can be assisted to move upward, without manually extending the cleaning device to the ceiling position, thereby reducing the labor of personnel.

[0053] In this optional solution, as Figure 2As shown in the figure, the transmission mechanism 42 includes a driving gear 421 fixed to the output end of the second driving motor 41, a support rod 422 vertically and rotatably supported in the installation box 1, a driven gear 423 fixed to the outer circle of the support rod 422, a connecting disk 424 fixed to the upper end of the driven gear 423, a threaded rod 425 vertically arranged and having its bottom end fixed to the connecting disk 424, and a threaded sleeve 426 threadedly sleeved on the outer circle of the threaded rod 425. The top end of the threaded sleeve 426 is fixedly connected to the mounting seat 2. The guide frame includes two second guide plates 431 spaced relatively apart and vertically fixed to the top end of the installation box 1, and a hollow plate 432 slidably penetrating through the outer circles of the two second guide plates 431. The threaded sleeve 426 is fixedly penetrated through the hollow plate 432.

[0054] During operation, by starting the second driving motor 41, the output end of the second driving motor 41 drives the driving gear 421 fixedly connected thereto to rotate through a coupling. The driving gear 421 meshes with the driven gear 423, thereby driving the driven gear 423 to rotate. The driven gear 423 drives the support rod 422 fixedly connected to its lower end to rotate on the bottom wall of the installation box 1. When the driven gear 423 rotates, the threaded rod 425 also rotates accordingly. When the threaded rod 425 rotates, under the limiting action of the hollow plate 432 and the second guide plates 431, the threaded sleeve 426 can move upward, thereby driving the mounting seat 2 and the hollow plate 432 to move upward. When the required height is reached, only the driving of the second driving motor 41 needs to be stopped. Therefore, by providing the lifting driving mechanism 4, it can be adjusted automatically according to the height of the ceiling, thereby improving the versatility of the device.

[0055] Optionally, as Figure 1 shown, the installation box 1 includes a hollow outer shell 11, four groups of rollers 12 connected to the four corners of the outer shell, and a handle 13 connected to one side of the installation box 1. During operation, by pushing the handle 13, the installation box 1 can be pushed to move, and the operation is convenient, time-saving and labor-saving.

[0056] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
