Description

Technical Field

[0001] This invention relates to a cleaning device and method, and more specifically, to a non-suction blowing dust collection and cleaning device and method having an inward rolling structure. Background Technology

[0002] With continuous technological advancements, various mechanical devices are moving towards full automation. To reduce manpower requirements, automated cleaning equipment is increasingly being introduced for both home and factory cleaning. For example, robotic vacuum cleaners have become a popular choice for home cleaning. Currently, most automatic floor cleaning devices on the market are suction-blowing dust collectors, which use pressure to generate airflow to suck in or blow away dust and debris. However, the airflow generated by suction-blowing dust collectors can cause turbulence in areas requiring strict indoor environmental control (such as cleanrooms and laboratories), leading to secondary pollution.

[0003] Besides suction-blowing cleaning equipment, adhesive cleaning rollers are also available on the market. These rollers rely on the adhesive force of surface cleaning paper to stick to dirt, unlike suction-blowing cleaning equipment which generates airflow. However, these products typically require manual operation, and the cleaning paper must be manually removed when the surface dirt no longer adheres to the roller for continued use. Therefore, while adhesive cleaning rollers avoid turbulence issues, they do not achieve automation to reduce labor requirements. In conclusion, automated cleaning equipment and methods that do not generate turbulence during cleaning are what the industry desires. Summary of the Invention

[0004] One object of the present invention is to provide a cleaning device and method that can achieve automated cleaning of target surfaces (e.g., floors).

[0005] One objective of this invention is to provide a cleaning device and method that can avoid generating turbulence, thereby preventing secondary pollution of equipment in cleanrooms, laboratories, and other spaces.

[0006] In one embodiment, the cleaning device includes a first take-up shaft, a first supply shaft, a frame, a first cleaning film, and a transmission assembly. The frame includes an outer surface and an internal space located inside the outer surface, wherein the outer surface has at least one notch communicating with the internal space, and the internal space accommodates the first take-up shaft and the first supply shaft arranged side by side. The first cleaning film has a supply portion, a take-up portion, and a middle portion, and the first cleaning film has an adhesive force. The supply portion is disposed on the first supply shaft, the take-up portion is disposed on the first take-up shaft, and at least a portion of the middle portion covers the outer surface of the frame, wherein both ends of the middle portion enter the internal space through the at least one notch and are respectively connected to the supply portion and the take-up portion. The transmission assembly is coupled to the first supply shaft and the first take-up shaft, and the transmission assembly drives at least one of the first supply shaft and the first take-up shaft to rotate during operation.

[0030] refer to Figure 1AThe cleaning device 100 according to a first embodiment of the present invention is described. The cleaning device 100 includes a hollow cylindrical frame 110. The frame 110 includes an outer surface 111, an internal space I of the hollow portion, and a notch 113 that cuts across the entire cylindrical surface. The internal space I accommodates a first take-up shaft 130 and a first supply shaft 150, wherein the first take-up shaft 130 is provided with a take-up portion 173 of the first cleaning film 170, and the first supply shaft 150 is provided with a supply portion 175 of the first cleaning film 170. In this embodiment, "provided" can refer to the take-up portion 173 and the supply portion 175 being wound around the axis of the first take-up shaft 130 and the first supply shaft 150 in a clockwise and counterclockwise manner, respectively. At least a portion 171 of the first cleaning film 170 covers the outer surface 111 and passes through the notch 113 into the internal space I, whereby it connects the supply portion 175 and the take-up portion 173, wherein the first cleaning film 170 has an adhesive force. It should be noted that the adsorption force described herein can be an adsorption force caused by contact or an adsorption force not caused by contact (such as electrostatic force), and the present invention does not limit it.

[0031] Continue to refer to Figure 1B In a variation of the embodiment, the cleaning device 100 further includes a transmission assembly 190 that, when in operation, drives at least one of the first supply shaft 150 and the first take-up shaft 130 to rotate. In this embodiment, the transmission assembly 190 includes a belt 191 and a handle 193. The belt 191 is coupled to both the first take-up shaft 130 and the first supply shaft 150 (e.g., via gears or toothed discs at the ends of the first take-up shaft 130 and the first supply shaft 150), and the handle 193 is coupled to the first supply shaft 150 (in different embodiments, the handle 193 may also be coupled to the first take-up shaft 130; this is not a limitation of the invention). Operation of the transmission assembly 190 means that when the handle 193 is rotated clockwise by an external force, the belt 191 responds to the clockwise rotation of the first supply shaft 150 and simultaneously drives the first take-up shaft 130 to rotate clockwise. Since the winding portion 173 and the supply portion 175 are wound around the first winding shaft 130 and the first supply shaft 150 in clockwise and counterclockwise directions respectively, when the first winding shaft 130 and the first supply shaft 150 rotate clockwise simultaneously, at least a portion of the supply portion 175 leaves the first supply shaft 150 to become the intermediate portion 171, and at least a portion of the intermediate portion 171 is wound around the first winding shaft 130 to become the winding portion 173. With this configuration, the intermediate portion 171 that originally covered the outer surface 111 is wound up by the first winding shaft 130, and the portion of the supply portion 175 provided on the first supply shaft 150 replaces the original intermediate portion 171 to cover the outer surface 111, thereby achieving the purpose of replacing the first cleaning film 170 on the outer surface 111.

[0032] It should be noted that the aforementioned winding and rotation directions (i.e., clockwise or counterclockwise) are illustrative examples. Other directions may also be used in different embodiments. For example, the winding portion 173 and the supply portion 175 may be wound in a counterclockwise and clockwise manner, respectively, and the first winding shaft 130 and the first supply shaft 150 may rotate counterclockwise. The present invention does not limit this.

[0033] In addition, the cleaning device 100 may also include a protective plate 195 and an anti-stick strip 197. The protective plate 195 is disposed at the axial end of the frame 110 (on one or both sides) to prevent dust and dirt from entering the internal space I. The anti-stick strip 197 is located at the notch 113 and extends parallel to the extension direction of the frame 110 and the notch 113. The anti-stick strip 197 does not protrude from the outer surface 111 and does not contact the frame 110; in other words, the anti-stick strip 197 divides the notch 113 into two parallel elongated gaps. In this embodiment, the anti-stick strip 197 is coupled to the protective plate 195 and is cylindrical. However, in different embodiments, the anti-stick strip 197 may also be of different shapes (e.g., rhomboid columnar), and the present invention does not limit this. With this configuration, when the two ends of the middle portion 171 enter the internal space I through the notch 113, they will be separated by the anti-stick strip 197, thereby preventing them from sticking to each other.

[0034] refer to Figure 2 The cleaning device 200 of the second embodiment of the present invention is described. The cleaning device 200 has a structure similar to that of the cleaning device 100 of the first embodiment, and further includes a second take-up shaft 230, a second supply shaft 250, and a second cleaning film 270. Furthermore, the notch 113 of the frame 110 further includes a first notch 213a and a second notch 213b, and the first notch 213a and the second notch 213b divide the outer surface 111 into a first outer surface 211a and a second outer surface 211b. The second cleaning film 270 has a middle portion 271, a take-up portion 273, and a supply portion 275, which are identical in structure to the first cleaning film 170. The take-up portion 273 is disposed on the second take-up shaft 230, and the supply portion 275 is disposed on the second supply shaft 250. The middle portions 171 and 271 of the first cleaning film 170 and the second cleaning film 270 respectively cover the first outer surface 211a and the second outer surface 211b, and the two ends of the middle portions 171 and 271 respectively enter the internal space I through the first notch 213a and the second notch 213b to connect the winding portions 173 and 273 and the supply portions 175 and 275. In addition, when the transmission assembly 190 is running, it can drive the first winding shaft 130, the second winding shaft 230, the first supply shaft 150, and the second supply shaft 250 to rotate clockwise or counterclockwise (see details). Figures 8A to 8D (as explained above), thereby achieving the purpose of replacing the cleaning film (i.e., the first cleaning film 170 and the second cleaning film 270) on the outer surface 111 as previously described.

[0035] refer to Figure 3A and Figure 3B The cleaning device 300 of the third embodiment of the present invention is described below. The cleaning device 300 may have a structure similar to that of the cleaning device 100 or 200, and further includes a cleaning wheel 310. It should be noted that, for the sake of simplicity, the cleaning device 300 is shown here in a manner similar to that of the cleaning device 100 (without the second take-up shaft 230 and the second supply shaft 250). The third embodiment described below with reference to the accompanying drawings may have the structure of the cleaning device 100 or 200. The present invention does not limit this, and this will be stated in advance.

[0036] Following on from above, first refer to Figure 3A The cleaning wheel 310 is positioned below the frame 110 and contacts the middle portion 171 covering the outer surface 111. The suction force of the cleaning wheel 310 is less than that of the first cleaning film 170. Since the axis of the cleaning wheel 310 is parallel to the axis of the frame 110, when the cleaning wheel 310 rotates, it drives the entire cleaning device 300 forward in a direction perpendicular to the axis of the frame 110, and the frame 110 rotates accordingly due to friction. It should be noted that although... Figure 3A Only one cleaning wheel 310 is shown, but in different embodiments there may be multiple cleaning wheels 310 (e.g., see reference 310). Figure 3B The present invention does not limit itself to a cleaning device 300 having two cleaning wheels 310.

[0037] refer to Figures 4A to 4C Continuing with the description of the cleaning device 300 according to the third embodiment of the present invention, since the cleaning wheel 310 has an adsorption force, when it comes into contact with dust, garbage, and other dirt on the target surface (e.g., the ground) during rotation, it will adsorb such dirt. Subsequently, since the adsorption force of the cleaning wheel 310 is less than that of the first cleaning film 170, when the part of it that has adsorbed dirt comes into contact with the middle part 171, the dirt is transferred to the first cleaning film 170. With this configuration, the cleaning device 300 can adsorb dirt from the target surface through the cleaning wheel 310 and then transfer the dirt to the first cleaning film 170, thereby maintaining the adsorption force of the cleaning wheel 310 and achieving the purpose of cleaning the target surface.

[0038] Figure 5A This is a disassembly diagram of the frame 110 and the transmission assembly 190 in one embodiment. Figure 5B for Figure 5A The illustrated embodiment shows a disassembled schematic diagram of the transmission assembly 190. In this embodiment, the transmission assembly 190 includes a gear disk 510 and a top plate 570, wherein the gear disk 510 has teeth around its periphery, and the tooth surface is recessed in the middle to accommodate the winding shaft gear 513 and the supply shaft gear 515 (see Figure 1). Figure 5BBoth the take-up shaft gear 513 and the supply shaft gear 515 have first tenon joints 530 on their tooth surfaces, located on the side opposite to the contact gear disk (i.e., the side facing the frame 110). Both the first take-up shaft 130 and the first supply shaft 150 have second tenon joints 550 located at their axial ends (i.e., the side facing the gear disk 510). The first tenon joints 530 and the second tenon joints 550 correspond to each other. Specifically, in this embodiment, the first tenon joint 530 and the second tenon joint 550 are polygonal protrusions and concave parts, respectively, with their shapes and sizes matching each other. When the transmission assembly 190 is coupled to the frame 110, the first tenon joint 530 and the second tenon joint 550 are engaged with each other. With this configuration, when the take-up shaft gear 513 and the supply shaft gear 515 rotate, the first tenon 530 drives the second tenon 550 to rotate, thereby causing the first take-up shaft 130 and the first supply shaft 150 to rotate as well, so as to achieve the purpose of replacing the first cleaning film 170 on the outer surface 111 as previously described.

[0039] Continuing from the above, the second take-up shaft 230 and the second supply shaft 250 can have the same structure as the first take-up shaft 130 and the first supply shaft 150. When the take-up shaft gear 513 and the supply shaft gear 515 rotate, the first tenon 530 drives the second tenon 550 to rotate, thereby causing the second take-up shaft 230 and the second supply shaft 250 to rotate accordingly, so as to replace the second cleaning film 270 on the outer surface 111. It should be noted that although the first tenon 530 is shown as a protrusion and the second tenon 550 as a concave part here, in different embodiments, the first tenon 530 and the second tenon 550 can also be other matching structures (for example, the first tenon 530 is a concave part and the second tenon 550 is a protrusion), and the present invention does not limit this.

[0040] refer to Figure 5B Continuing with this embodiment, the top plate 570 of the cleaning device 300 is coupled to the gear disk 510 to prevent dirt from entering the gear disk 510. The top plate 570 has top plate holes 571 (the number of which corresponds to the total number of the first take-up shaft 130, the first supply shaft 150, the second take-up shaft 230, and the second supply shaft 250) positioned to correspond to the take-up shaft gear 513 and the supply shaft gear 515, allowing the first tenon 530 to pass through the top plate holes 571 and couple with the second tenon 550. It should be noted that although the top plate holes 571 are shown as circular in this embodiment, their purpose is merely to allow the first tenon 530 to pass through without being obstructed by the top plate 570; therefore, they can be of any suitable shape (e.g., a polygon identical to the first tenon 530), and the present invention does not limit this.

[0041] refer to Figure 5AThe top plate 570 may further include a tenon 573 and an alignment member 575, and in this embodiment, the cleaning device 300 may also include a guard plate 195 as in the first embodiment, disposed at both ends of the frame 110. The guard plate 195 has holes to expose the ends of the first take-up shaft 130 and the first supply shaft 150, and the guard plate 195 further includes a mortise 577 and an alignment member 579 (see...). Figure 5A The tenon 573 corresponds to the mortise 577, allowing the transmission component 190 to engage with the frame 110. The alignment mother 575 corresponds to the alignment daughter 579 (e.g., the alignment mother 575 is a long protrusion, and the alignment daughter 579 is a long groove of the same shape as the alignment mother 575), facilitating quick alignment when engaging the transmission component 190 with the frame 110. It should be noted that the aforementioned tenon 573, mortise 577, alignment mother 575, and alignment daughter 579 are merely illustrative examples. Other configurations may exist in different embodiments (e.g., the tenon 573 is located on the guard plate 195, and the mortise 577 is located on the top plate 570, etc.). This invention does not limit this.

[0042] Figure 6A The internal structure of the gear disk 510 in one embodiment is shown, and Figure 6B yes Figure 6A The illustrated embodiment shows a rear side view of the gear disk 510. In this embodiment, the cleaning device 300 further includes a control element 610 that penetrates the gear disk 510. A control gear 611 is provided inside the gear disk 510, and a limiting element 613 is provided outside the gear disk 510 (i.e., on the side without the winding shaft gear 513 and the supply shaft gear 515). (For a description of the limiting element, please refer to...) Figure 7A , Figure 7B and Figure 7C The limiting element 613 and the control gear 611 are linked (that is, when the limiting element 613 is fixed, the control gear 611 will not be able to rotate; when the limiting element 613 is rotated, the control gear 611 will rotate accordingly), and the control gear 611 meshes with the winding shaft gear 513 and the supply shaft gear 515 respectively.

[0043] refer to Figure 7A Continuing with the description of the cleaning device 300 of the third embodiment of the present invention, in this embodiment, the cleaning device 300 further includes a drive module 650, which includes a retainer 655 for fixing the limiting element 613. Figure 7AThe limiting element 613 and its corresponding retainer 655 are shown. In this embodiment, the limiting element 613 is a gear (hereinafter referred to as the fixed gear), and the retainer 655 has a shape corresponding to the tooth profile of the fixed gear. Specifically, the retainer 655 may have a protrusion that can appropriately fill the tooth groove of the fixed gear (e.g., the distribution position of the protrusion is the same as the tooth groove, and the width of the protrusion is the same as the tooth groove width, etc.). In this configuration, when the retainer 655 is engaged with the limiting element 613, the fixed gear can be fixed and prevented from rotating (see reference). Figure 7B This leads to the control gear 611, which is fixedly installed within the gear disk 510, to achieve, for example... Figure 8A and Figure 8B The first operating mode of the transmission component 190 is described.

[0044] It should be noted that although the limiting element 613 is shown as a gear in this embodiment, the limiting element 613 may also be in other forms in different embodiments, such as those described in reference to [reference needed]. Figure 7C The limiting element 613 can be in the form of a pin hole, while the retainer 655 can be in the form of a pin or any other form that can achieve the purpose of fixing the limiting element 613 with the retainer 655. The present invention does not limit this.

[0045] refer to Figure 8A and Figure 8B This describes the first operating mode of the transmission assembly 190 in the above embodiment (for the second operating mode, please refer to [reference needed]). Figure 8C and Figure 8D (Related Explanation). In this embodiment, the drive module 650 further includes a drive gear 653 disposed around the gear disk 510, wherein when the drive module 650 receives power, the drive gear 653 will rotate, and the drive gear 653 can mesh with the tooth profile of the gear disk 510. As described above, when the transmission assembly 190 is running, it will drive the first take-up shaft 130 and the first supply shaft 150 to rotate, thereby achieving the purpose of replacing the middle portion 171 of the first cleaning film 170 on the outer surface 111. The operation of the transmission assembly 190 includes rotating the take-up shaft gear 513 and the supply shaft gear 515, the structure and process of which will be described below.

[0046] refer to Figure 8A and Figure 8BSince the control gear 611 meshes with the take-up shaft gear 513 and the supply shaft gear 515, when the drive gear 653 meshes with the gear disk 510 and rotates, and the limiting element 613 of the fixed control element 610 prevents the control gear 611 from rotating, the take-up shaft gear 513 and the supply shaft gear 515 respond to the rotation of the gear disk 510 and begin to rotate relative to the fixed control gear 611 (i.e., revolve around the control gear 611). Due to the meshing relationship between the take-up shaft gear 513 and the supply shaft gear 515 and the control gear 611, the stationary control gear 611 will drive the take-up shaft gear 513 and the supply shaft gear 515 to rotate (rotate), thereby causing the transmission assembly 190 to operate and perform the take-up operation.

[0047] It should be noted that in this embodiment, the number of teeth on the supply shaft gear 515 can be greater than that on the take-up shaft gear 513, so that the rotational speed of the take-up shaft gear 513 and the first take-up shaft 130 is faster than that of the supply shaft gear 515 and the first supply shaft 150. In this configuration, the speed at which the first take-up shaft 130 retracts the intermediate portion 171 will be faster than the speed at which the first supply shaft 150 provides a new intermediate portion 171, allowing the first cleaning film 170 to adhere tightly to the outer surface 111.

[0048] refer to Figure 8C and Figure 8D This invention describes a second operating mode of the transmission assembly 190 of the cleaning device 400 according to an embodiment of the present invention. In this embodiment, the drive gear 653 of the drive module 650 fixes the gear disk 510 so that it cannot rotate, and the drive module 650 drives the control gear 611 to rotate, while simultaneously engaging the take-up shaft gear 513 and the supply shaft gear 515 to rotate, thereby achieving the purpose of replacing the first cleaning film 170 on the outer surface 111. It should be noted that, as described in the third embodiment, the number of teeth on the supply shaft gear 515 can be greater than that on the take-up shaft gear 513, so that the rotational speed of the take-up shaft gear 513 and the first take-up shaft 130 is faster than that of the supply shaft gear 515 and the first supply shaft 150. Under this configuration, the speed at which the first take-up shaft 130 retracts the intermediate portion 171 will be faster than the speed at which the first supply shaft 150 provides a new intermediate portion 171, so that the first cleaning film 170 can adhere tightly to the outer surface 111.

[0049] refer to Figure 9A Continuing with the description of the cleaning device 300 according to the third embodiment of the present invention, Figure 9AThe side structure of the cleaning device 300 is shown. In this embodiment, the cleaning device 300 further includes a lifting module 910 for lifting the frame 110. Specifically, the lifting module 910 includes a semi-circular hollow support element 911, the diameter of which is slightly larger than that of the gear disk 510, so that its hollow portion can properly accommodate and support the gear disk 510. When the lifting module 910 is driven to rise, the support element 911 will exert an upward force on the gear disk 510, thereby lifting the frame 110. It should be noted that although the support element 911 is shown in the form of a semi-circular hollow in this embodiment, in different embodiments the support element 911 may also be other shapes that can properly support the gear disk 510 (e.g., a three-quarter circle), and the present invention does not limit this.

[0050] Continuing from above, for reference Figure 9B Continuing with the description of the cleaning device 300 according to the third embodiment of the present invention, Figure 9B A schematic diagram of the lifting module 910 lifting the frame 110 is shown. As can be seen from the diagram, when the lifting module 910 lifts the frame 110, the cleaning wheel 310 no longer contacts the frame 110, and the frame 110 is no longer subject to the frictional force generated by the cleaning wheel 310, thus stopping its rotation. Furthermore, when the lifting module 910 lifts the frame 110, the limiting element 613 of the transmission assembly 190 is coupled to the retainer 655 of the drive module 650, and the drive gear 653 of the drive module 650 meshes with the gear disc of the transmission assembly 190 (e.g., ...). Figure 7B (As shown). In this configuration, when the lifting module 910 and the drive module 650 are powered, the lifting module 910 lifts the frame 110, the drive module 650 is coupled to the transmission assembly 190, and the drive gear 653 begins to rotate, thereby causing the first take-up shaft 130 and the first supply shaft 150 to rotate, so as to perform the following... Figure 8A and Figure 8B The process of replacing the cleaning membrane is shown.

[0051] refer to Figures 10A to 10D The cleaning device 300 according to a third embodiment of the present invention is described. In this embodiment, the cleaning device 300 further includes a monitoring unit 1010, which may include sensors such as a camera. Figures 10 to 10 Figure 10D This diagram illustrates a procedure for replacing the middle portion 171 of the outer surface 111 based on the monitoring results of the monitoring unit 1010. The sensing range of the monitoring unit 1010 includes at least a portion of the outer surface 111, thereby acquiring an image containing the middle portion 171 covering the at least portion of the outer surface 111. Based on this image, the monitoring unit 1010 can further determine the adsorption force of the middle portion 171 of the first cleaning film 170. When the monitoring unit 1010 determines that the adsorption force of the middle portion 171 is less than a preset threshold, it drives the lifting module 910 and the driving module 650, thereby executing the following... Figure 8Aand Figure 8B or Figure 8C and Figure 8D The procedure described is for replacing the middle portion 171 of the first cleaning membrane 170.

[0052] Continuing from the above, when monitoring unit 1010 determines that the adsorption force of the middle part 171 is less than the threshold (refer to...) Figure 10A The lifting module 910 lifts the frame 110, at which point the frame 110 stops rotating (see reference). Figure 10B Next, the drive module 650 drives the transmission assembly 190 to operate, that is, the drive gear 653 meshes with the gear disk 510 to rotate (and simultaneously drives the frame 110 to rotate, see reference). Figure 10C This process causes the first roll reel 130 to reclaim the previously contaminated middle section 171, while the first supply roll 150 provides a clean middle section 171 to replace it. Finally, after the cleaning membrane replacement is complete, the lifting module 910 lowers the frame 110 (see reference). Figure 10D In this configuration, the monitoring unit 1010 can ensure that the middle portion 171 maintains adsorption force. In addition, since the cleaning wheel 310 continues to rotate during the replacement of the cleaning film, the dirt on the target surface will still be adsorbed by the cleaning wheel 310. When the lifting module 910 lowers the frame 110, the middle portion in contact with the cleaning wheel 310 will adsorb the dirt again, thereby maintaining the cleanliness of the target surface.

[0053] refer to Figures 11A to 11C This describes a procedure 1100 for determining the adsorption force of the intermediate portion 171 according to an embodiment of the present invention. At 1101, an image 1120 (e.g., image 1120) including at least a portion of the intermediate portion 171 is acquired by a monitoring unit 1010. Figure 11B The monitoring unit 1010 may include an image sensor, such as a complementary metal-oxide-semiconductor (CMOS) or charge-coupled device (CCD) image sensor. (See reference...) Figure 11B In image 1120, the background area represents the first cleaning film 170, and the black dots distributed on it are dirt adsorbed by the first cleaning film 170. (Continue to refer to...) Figure 11A At point 1103, appropriate image processing can be performed on image 1120, such as cropping foreground and background objects to reveal the dirty areas (see...). Figure 11CThe processed image 1121 is shown. At 1105, the distribution of dirt is calculated using object marking technology. Then at 1107, the dirt percentage (i.e., the ratio of the dirt area to the first cleaning film 170) is calculated based on the calculated dirt distribution. At 1109, based on the calculated dirt percentage, the monitoring unit 1010 can determine whether the current adsorption force of the middle portion 171 of the first cleaning film 170 is less than a threshold (e.g., if the dirt percentage is greater than 85%, the adsorption force is determined to be less than the threshold). At 1111, when the monitoring unit 1010 determines that the adsorption force of the middle portion 171 of the first cleaning film 170 is less than a certain threshold, the process described above is executed. Figures 10A to 10D Instructions for replacing the cleaning membrane.

[0054] refer to Figure 12 This describes the anti-reverse device 1210 according to a third embodiment of the present invention. In this embodiment, the winding shaft gear 513 and the supply shaft gear 515 rotate counterclockwise (see [link]). Figure 8A and Figure 8B To prevent the take-up shaft gear 513 and the supply shaft gear 515 from rotating in the wrong direction (e.g., clockwise), causing the soiled middle portion 171 to re-cover the outer surface 111 of the frame 110, and the clean middle portion to rewind back onto the first supply shaft 150, this embodiment further includes an anti-reverse device 1210. The anti-reverse device 1210 can be disposed beside the take-up shaft gear 513 and / or the supply shaft gear 515, wherein the anti-reverse device 1210 includes a needle tip 1213 and a blocking member 1215. The needle tip 1213 is disposed within a tooth groove, and when the take-up shaft gear 513 and / or the supply shaft gear 515 rotates counterclockwise, it will deflect the needle tip 1213 in a direction opposite to that of the blocking member 1215, without being obstructed by the blocking member 1215. Conversely, when the take-up shaft gear 513 and / or the supply shaft gear 515 rotate clockwise, the needle tip 1213 will be pushed toward the blocking member 1215. At this time, the needle tip 1213 is blocked by the blocking member 1215, thereby preventing the take-up shaft gear 513 and / or the supply shaft gear 515 from rotating clockwise.

[0055] It should be noted that although the anti-reverse device 1210 is configured in this embodiment to prevent the take-up shaft gear 513 and / or the supply shaft gear 515 from rotating clockwise, the anti-reverse device 1210 can be configured in different ways as needed in different embodiments (e.g., to prevent the take-up shaft gear 513 and / or the supply shaft gear 515 from rotating counterclockwise), and the present invention does not limit this. In addition, the anti-reverse device 1210 can also be configured next to gears other than the take-up shaft gear 513 and / or the supply shaft gear, for example, referring to... Figure 8C and Figure 8D In one embodiment, the anti-reverse device 1210 can also be located next to the control gear 611 to prevent it from rotating counterclockwise.

[0056] refer to Figure 13 The fifth embodiment of the present invention provides a cleaning method, which may include the method performed by the cleaning device in any of the preceding embodiments. For example, in this embodiment, the method includes at least the following steps: At 1301, the method includes adsorbing dirt on the target surface with at least one cleaning wheel 310 and then adsorbing dirt on the cleaning wheel 310 with the intermediate portion 171. At 1303, the method includes determining the state of the intermediate portion 171 with a monitoring unit 1010 and generating a determination result. At 1305, the method includes driving the drive module 650 and the lifting module 910 based on the determination result that the adsorption force of the intermediate portion 171 is less than a threshold. At 1307, the lifting module 910 lifts the frame 110, while the drive module 650 drives the transmission assembly 190 to replace the intermediate portion 171. And, at 1309, the lifting module 910 lowers the frame 110, completing the cleaning film replacement procedure.
