Description

[Technical Field]

[0001] The present invention relates to the technical field of ground cleaning devices, and more particularly to a wiping device and a cleaning device for cleaning ground surfaces. [Background technology]

[0002] In conventional cleaning devices, when replacing or maintaining a rolling brush with an internal drive motor, water can enter the drive motor from the water tank, increasing the risk of electric shock and potentially damaging the drive motor. Furthermore, because the drive motor is internally mounted, heat dissipation from the drive motor cannot be effectively implemented. The drive motor can easily be damaged by operating in a high-temperature environment for a long period of time.

[0003] Cleaning devices are typically made of plastic. Because plastic parts are manufactured by injection molding, plastic parts with complex structures cannot be manufactured using injection molding. To solve this problem, multiple small parts can be manufactured and then assembled to obtain the cleaning device. However, when the cleaning device has a complex structure, a cleaning device assembled from multiple small parts has the disadvantage of being unstable and easily damaged.

[0004] Commonly used floor cleaning devices include vacuum cleaners, sweeping robots, mops, etc. These devices sweep floors with wet or dry rags or wipe floors with wet or dry rags. When wiping floors with wet or dry rags, a large amount of water is left on the floor, which can cause the user to slip and fall. Furthermore, stepping on wet surfaces can contaminate the floor, making them inconvenient to use. Currently available floor scrubbers have the functions of sweeping floors with wet or dry rags and wiping floors with wet or dry rags. Conventional floor scrubbers squeeze out dirty water from a rolling brush by rubbing it with wiper blades, which does not achieve the effect of wiping a floor with a dry rolling brush. Furthermore, rubbing the rolling brush with the wiper blades can easily damage the wiper blades and rolling brush, and can also create a large resistance force on the rolling brush. Furthermore, conventional cleaning devices have the drawbacks of being heavy, not cleaning efficiently, and not being convenient to use.

[0005] It is necessary to provide new technical means to solve the problems of the conventional technology. Summary of the Invention [Problem to be solved by the invention]

[Effects of the Invention]

[0024] Compared with the prior art, the technical features of the present invention can achieve at least one or more inventive effects. The cleaning device of the present invention has an ingenious design, a simple structure, easy operation, and is convenient to use. The device is modularized, easy to assemble, and each part can be easily replaced or maintained, thereby improving the cleaning effect.

[0025] The support frame is formed by metal stretch molding, allowing for stable support of the cleaning device. Conventional support frames are largely made of plastic, and due to limitations in the manufacturing process, it is difficult to mold the conventional support frame as a single unit. To stably support the cleaning device using a conventional support frame, the support frame must be thick, which increases the weight of the support frame and may affect the structural simplicity and stability of the device. While cleaning devices can be obtained by assembling multiple parts, such cleaning devices have the disadvantage of being unstable and easily damaged. This may affect the structural simplicity and stability of the cleaning device.

[0026] The cleaning device of the present invention is equipped with a screw conveyor rod. The screw conveyor rod is attached so as to be close to or abut against a rolling brush, and the screw conveyor rod and rolling brush rotate in opposite directions. Compared to the conventional technology of using wiper blades to remove water and contaminants from the rolling brush, the present invention employs a technology in which the cylindrical screw conveyor rod and the rolling brush rotate in opposite directions while abutting each other. This reduces the resistance applied to the rolling brush, reduces damage to the rolling brush, significantly reduces the resistance force that causes the rolling brush to rotate forward, reduces the power required to drive the rolling brush, reduces wear on the surfaces of the rolling brush and the screw conveyor rod, and extends the life of the device. The screw conveyor rod presses the rolling brush, squeezing out dirty water and / or particulate contaminants from the rolling brush and turning the rolling brush into a semi-moist, slightly damp, or slightly dry state. This improves the effectiveness of automatic cleaning and squeezing out water from the rolling brush.

[0027] The cleaning device of the present invention is equipped with a screw conveyor rod. A spiral recess is formed on the screw conveyor rod, which transports squeezed wastewater and / or particulate contaminants from one end of the screw conveyor rod to a wastewater / contaminant guide port at the other end. By providing a clean water inlet and a wastewater / contaminant guide port at both ends of the screw conveyor rod, space can be saved, allowing for a more compact device and more diverse design. The clean water inlet and wastewater / contaminant guide port can also be located at other positions. Due to the spiral recess formed on the screw conveyor rod, the surface of the screw conveyor rod is uneven. When the screw conveyor rod rotates while pressing against the rolling brush, the uneven surface of the screw conveyor rod kneads, beats, and pushes the flexible cleaning layer on the surface of the rolling brush, thereby improving the cleaning effect and squeezing out water from the surface of the rolling brush.

[0028] The cleaning apparatus of the present invention is equipped with an impeller device. As the impeller rotates, centrifugal force is applied to wastewater and / or particulate contaminants, which can be sent into the wastewater tank by centrifugal force. The cleaning apparatus of the present invention can send wastewater and / or particulate contaminants into the wastewater tank without installing an absorber. When an absorber is installed in the cleaning apparatus, the suction force of the absorber can be reduced, thereby reducing power consumption. Furthermore, in a cleaning apparatus equipped with an absorber, when wastewater and / or particulate contaminants cannot be sent into the wastewater tank, the absorber can be used as an auxiliary device. The cleaning apparatus of the present invention is equipped with an impeller drive motor. The impeller drive motor can control the rotation speed of the impeller, and the rotation speed of the impeller and the rotation speed of the screw conveyor rod can be the same or different. The impeller rotates at high speed when driven by the impeller drive motor, thereby improving the efficiency of discharging wastewater and / or particulate contaminants.

[0029] The cleaning device of the present invention is equipped with a pressure roller module. The pressure roller module effectively removes water and blocks large particulate contaminants. The pressure roller module is attached so as to be close to or in contact with the rolling brush, and the pressure roller module and the rolling brush rotate in opposite directions. Compared to the conventional technology in which a fixed wiper blade abuts against the rotating rolling brush, the present invention reduces the resistance force applied to the rolling brush, reduces the power required to drive the rolling brush, and prevents damage to the surfaces of the rolling brush and pressure roller module. Compared to the conventional technology in which a wiper blade is used to remove water and contaminants from the rolling brush, the use of a pressure roller module in the present invention reduces the resistance force applied to the rolling brush, reduces damage to the rolling brush, significantly reduces the resistance force that causes the rolling brush to rotate forward, reduces the power required to drive the rolling brush, reduces wear on the rolling brush surface, and extends the life of the device.

[0030] The cleaning device of the present invention is equipped with a pressure roller module. The cylindrical pressure roller module and the rolling brush rotate in contact with each other, thereby pressing the rolling brush more firmly and making the rolling brush semi-moist, slightly damp, or slightly dry. The pressure roller module is further installed, and the pressure roller module and the screw conveyor rod perform double squeezing, which more effectively removes dirty water and / or particulate contaminants from the rolling brush, ensuring the operation of the rolling brush, improving the efficiency of cleaning the rolling brush, and preventing water and contaminants from remaining on the ground after cleaning.

[0031] The cleaning device of the present invention is provided with a wastewater storage unit, and a wastewater / pollutant guide passage is formed by the screw conveyor rod and the wastewater storage unit to guide wastewater, fresh water, and pollutants. By guiding the wastewater, fresh water, and pollutants through the wastewater / pollutant guide passage, the problem of the prior art ineffective removal of wastewater and pollutants is solved. In the wastewater storage unit, an included angle θ is formed between the upper and lower edges of the opening of the wastewater storage unit. The included angle θ is in the range of 180° to 270°, and by appropriately designing the included angle θ, the wastewater storage unit can fully surround the rolling brush. This ensures that the wastewater and / or particulate pollutants on the rolling brush enter the wastewater storage unit and prevents the wastewater and / or particulate pollutants from overflowing. In addition, by increasing the angle θ at which the wastewater storage section surrounds the rolling brush, the completeness of the transport path of the screw conveyor rod can be ensured, and the screw conveyor rod can transport more wastewater and / or particulate contaminants to the impeller device or wastewater tank side.

[0032] The cleaning device of the present invention is equipped with an adjustment component, which allows the user to adjust the distance and contact degree between the screw conveyor rod and the rolling brush, or the distance and contact degree between the pressure roller module and the rolling brush, according to the actual situation, user needs, and usage effect, to achieve the optimal cleaning effect.

[0033] The cleaning device of the present invention is equipped with a first toothed comb and / or brush. The rack or brush bristles are in point-to-surface contact with the rolling brush. Conventional wiper blades or pressure rods are in surface-to-surface contact with the rolling brush. When soft contaminants such as hair or noodles adhere to the rolling brush, the surface-to-surface contact between the wiper blade or pressure rod and the rolling brush prevents the wiper blade or pressure rod from removing the soft contaminants from the rolling brush, and the soft contaminants may adhere more firmly to the rolling brush. When the first toothed comb and / or brush with point-to-surface contact is used in the present invention, the rack or brush bristles on the first toothed comb and / or brush can effectively remove soft contaminants from the rolling brush. Effectively removing soft contaminants from the rolling brush improves the efficiency of soft contaminant removal and allows for more thorough cleaning of the ground. When the pressure roller module and the rolling brush rotate in contact with each other, water may collect below the roller module. In this case, the first toothed comb and / or brush can guide a large amount of accumulated water into the wastewater storage section, preventing the accumulated water from splashing in various places and leaving a large amount of water on the ground.

[0034] The cleaning device of the present invention is equipped with a second toothed comb and / or brush. After the pressure roller module presses the rolling brush to remove sewage and / or particulate contaminants from the rolling brush, the fleece absorbent layer on the surface of the rolling brush is brought into contact with the roller bearing, and the fleece absorbent layer abutting the roller bearing continues to rotate in the forward direction. When the rolling brush is brought into contact with the ground, the fleece absorbent layer of the rolling brush 1 abuts the ground, significantly reducing the rolling brush's ability to absorb sewage and / or particulate contaminants. In the present invention, the pressure roller module presses the rolling brush, forming a second toothed comb and / or brush on the surface of the pressure roller module that abuts the rolling brush. The fleece absorbent layer is scrubbed with racks or brush hairs, causing it to expand. The expanded fleece absorbent layer can effectively absorb sewage and / or particulate contaminants on the ground.

[0035] Conventional floor scrubbers have the functions of sweeping floors with wet and dry rags and mopping floors with wet and dry rags. However, conventional floor scrubbers typically use wiper blades to rub the rolling brush to squeeze out dirty water from the rolling brush, which does not achieve the effect of wiping a floor with a dry rolling brush and does not effectively remove dirt and dirty water from the rolling brush. Furthermore, such devices have drawbacks: they are expensive to sell, have a complex structure, and are easily damaged. Increasing the pressure applied by the wiper blades to the rolling brush can effectively squeeze out water from the rolling brush, but this increases the resistance applied to the rolling brush, which can damage the rolling brush. Furthermore, even if the pressure applied by the wiper blades to the rolling brush is increased, the water and dirt on the rolling brush cannot be sufficiently removed. When the fixed wiper blades abut against the rotating rolling brush, the resistance applied to the rolling brush increases, reducing the efficiency of pushing the rolling brush, which can easily damage the wiper blades and rolling brush, and can also cause excessive resistance to the rolling brush. If the pressure applied by the wiper blades to the rolling brush is reduced, the dirty water on the rolling brush may not be sufficiently removed, resulting in water remaining on the ground after cleaning. In the present invention, the pressure applied to the rolling brush can be easily adjusted by using the spiral convex portion formed on the screw conveyor rod. Furthermore, the cylindrical screw conveyor rod and the rolling brush rotate in opposite directions while in contact with each other, thereby reducing the resistance applied to the rolling brush and improving the squeezing effect, thereby thoroughly squeezing the dirty water from the rolling brush and effectively removing the contaminants. Furthermore, the spiral concave portion formed on the screw conveyor rod forms a contaminant transport passage, effectively guiding the dirty water and / or particulate contaminants. The cleaning device is equipped with a fresh water tank and pump to deliver fresh water to the rolling brush, enabling automatic cleaning of the rolling brush and optimizing the device design.In addition, the cylindrical pressure roller module and the rolling brush rotate in contact with each other, which presses the rolling brush more firmly and squeezes out the water inside the rolling brush more effectively. It also blocks large particulate contaminants and reduces the resistance applied to the rolling brush.

[0036] The drive structure is mounted inside the rolling brush, which simplifies the structure, saves installation space, and reduces modules and volume, thereby making the device lighter, more portable, and simpler, and reducing manufacturing costs.

[0037] When the rolling brush is removed from the cleaning device, the drive structure mounted within the rolling brush can be removed together, improving ease of operation and use and preventing dirty water and / or particulate contaminants on the rolling brush from entering the drive structure, which could cause a short circuit in the drive structure's lines or damage the drive structure.The drive structure within the rolling brush is electrically connected to the device body, simplifying the structure, improving ease of use, and achieving an ingenious design, as well as facilitating installation and removal of the rolling brush.

[0038] A detachable part is attached to one end of the rolling brush, allowing for easy attachment and detachment of the drive mechanism within the rolling brush. To prevent the detachable part from getting into water, a mistake-proof button is designed at the attachment / detachment site to prevent unauthorized removal of the drive mechanism. The drive mechanism within the rolling brush can be removed simply by pressing the button and rotating the detachable part. Once the button is clicked or not pressed, the drive mechanism within the rolling brush cannot be removed even by rotating the detachable part. This prevents the drive mechanism within the rolling brush from falling off due to incorrect rotation of the detachable part. The detachable part also serves to support the drive mechanism, and is fixed to the drive structure. Because the drive structure is fixed to the detachable part, the drive structure rotates with the detachable part, but not with the rolling brush itself.

[0039] The motor in the drive structure is electrically connected to the support frame by a detachable part. The electric wire of the motor passes through a hollow bolt and extends into the detachable part. A waterproof electrical connection structure is formed on the detachable part, and a waterproof locking structure is formed on the support frame, so that the detachable part is electrically connected to the support frame in a detachable and sealed state. This structure makes it easy to install and remove the rolling brush module, and allows the rolling brush module to be removed or assembled in one go. It also prevents water from entering the drive structure or wiping device, which could cause damage to the device.

[0040] The rolling brush is formed with an anti-jamming structure, and when the rolling brush cannot rotate due to interference, the anti-jamming structure can support the driving of the driving structure to protect the motor.

[0041] By forming a heat dissipation passage in the rolling brush, which has a drive mechanism mounted therein, and using the heat dissipation passage to dissipate heat from the drive mechanism (i.e., the motor) inside the rolling brush, the temperature of the motor can be lowered and the motor can be prevented from burning out due to high temperatures. Furthermore, by lowering the temperature of the motor, the rotation speed of the motor can be increased, improving the cleaning speed and efficiency of the rolling brush and meeting user requirements. A large amount of heat is generated when the motor inside the rolling brush operates. Because the motor is mounted inside the rolling brush, the heat cannot be effectively dissipated, so the rotation speed of the motor inside the rolling brush is usually set to 200-400 rpm. If the rotation speed of the motor is too high, the temperature of the motor will rise and the motor may be burned out. If the rotation speed of the motor is too low, the cleaning speed will be slow and the cleaning efficiency will be reduced, failing to meet user requirements. To increase the rotation speed of the motor, the quality of the motor must be improved. For example, in a conventional cleaning device in which a motor is attached to the outside of a rolling brush, a motor with a rotational speed of 7000 rpm is attached to the outside of the rolling brush (to ensure operational stability), but the motor normally operates at a rotational speed of 1000 rpm. In a conventional cleaning device in which a motor is attached inside the rolling brush, the motor with a rotational speed of 7000 rpm normally operates at a rotational speed of 2400 rpm. While these two rolling brushes can meet user needs, using a high-quality motor increases the manufacturing and operating costs of the cleaning device, making it unsuitable for mass use in ordinary households. The optimal way to ensure high-speed operation of the motor without increasing costs is to create a heat dissipation path in the rolling brush to dissipate heat from the motor, lower the temperature of the motor, and maintain high-speed operation.

[0042] The waterproof cover prevents water from entering the storage space and the waterproof cotton as much as possible. In addition, the height of the waterproof protrusion is higher than the height of the second end cover, so water can be prevented from entering the through-hole even when the rolling brush is placed vertically or horizontally.

[0043] When using a cleaning device, the rolling brush must always be replaced. By attaching or detaching the rolling brush and its internal drive mechanism together, the convenience of replacing the rolling brush can be greatly improved. Furthermore, by attaching the rolling brush to the device body using a coupling means or a magnetic attraction means, the rolling brush can be easily replaced and the replacement process can be made more convenient. The drive mechanism inside the rolling brush can be detached from the rolling brush. When replacing the rolling brush, the drive mechanism can be removed from the storage space and then reattached to the new rolling brush. Next, the new rolling brush with the attached drive mechanism is attached to the device body, completing the replacement of the rolling brush. When replacing the rolling brush, only the roller bearing with the attached flexible cleaning layer needs to be replaced, and the drive mechanism can be reused, thereby reducing usage costs.

[0044] The free end of the operating rod can rotate freely, which improves the convenience of the user when rotating the operating rod. In addition, a positioning rib is formed on the operating rod and a positioning coupling recess is formed on the fixed part, and the positioning rib is coupled into the positioning coupling recess, allowing the operating rod to stand vertically. In other words, the operating rod can be stably stood when not in use.

[0045] The wastewater tank can be easily attached by connecting it to the fixed parts of the support frame. A detachable button is attached, and the wastewater tank can be easily removed by rotating the detachable button. This makes it easy to remove wastewater and contaminants from the wastewater tank or to clean the wastewater tank. Even women with weak strength can easily remove the wastewater tank, improving convenience of use.

[0046] The cleaning device of the present invention is equipped with a fresh water tank, so that when the rolling brush removes sewage and contaminants, the rolling brush can be washed with the fresh water in the fresh water tank. This realizes the automatic cleaning function of the rolling brush and allows for a more thorough cleaning of the ground. In addition, the installation of a sliding coupling structure allows various fresh water tanks with different volumes to be attached to the operating rod, improving convenience in use.

[0052] Example 1 to 47, the cleaning equipment according to the embodiment of the present invention includes a wiping device, a dirty water tank 71, a fresh water tank 72, and an operating rod 8.

[0053] In an embodiment of the present invention, as shown in FIGS. 1 to 37 and 39 to 41, the wiping device includes a rolling brush 1, a cleaning module, a pressure roller module 3, and a support frame 6. The rolling brush 1, cleaning module, and pressure roller module 3 are all removably mounted on the support frame 6. The dirty water tank 71 is removably mounted on one side of the support frame 6 away from the rolling brush 1, and the wiping device is connected to the dirty water tank 71. The wiping device processes water and / or contaminants, the dirty water tank 71 collects water and / or contaminants from the wiping device, and the support frame 6 can prevent the dirty water and / or particulate contaminants from overflowing from the wiping device. As shown in FIGS. 4 and 6, the operating rod 8 is rotatably mounted on the support frame 6, and the clean water tank 72 is removably mounted on the operating rod 8.

[0054] As shown in Figures 32 and 33, the support frame 6 includes an integrally molded support frame body 61, which is attached to the rear side of the rolling brush 1 in the forward direction. The support frame body 61 is formed with a wastewater storage section 62, a pressure roller storage section 63, and an integration components storage section 64 having at least one opening, the axial direction of the wastewater storage section 62 and the axial direction of the pressure roller storage section 63 being aligned, the pressure roller storage section 63 being formed above the wastewater storage section 62, and both the openings of the pressure roller storage section 63 and the wastewater storage section 62 facing the rolling brush. Preferably, the integration components storage section 64 is formed on one side of the wastewater storage section 62 away from the rolling brush 1. Openings are formed at both ends of the integration components storage section 64, and a through-hole is formed inside. The wastewater storage compartment 62 and the pressure roller storage compartment 63 have through-holes formed in the interior thereof in the longitudinal direction, penetrating the wastewater storage compartment 62 and the pressure roller storage compartment 63. The support frame body 61 is a metal support frame. The axial directions of the integrated component storage compartment 64, the wastewater storage compartment 62, and the pressure roller storage compartment 63 are aligned. A screw conveyor rod 21 is rotatably mounted within the wastewater storage compartment 62. The pressure roller module 3 is rotatably mounted within the pressure roller storage compartment 63, and a pump energy storage device is detachably mounted within the integrated component storage compartment 64. A first case cover 65 is detachably mounted to one end of the support frame body 61, and a second case cover 66 is detachably mounted to the other end of the support frame body 61. The support frame 6 serves to support the entire cleaning device. The support frame 6 is formed by metal stretch forming, thereby providing stable support for the cleaning device. The conventional support frame is mostly made of plastic, and the bounded nature of the manufacturing process makes it difficult to mold the conventional support frame as a single unit. In order for the conventional support frame to stably support the cleaning device, the thickness of the support frame needs to be increased, which increases the weight of the support frame and may affect the simplicity of the device structure and the stability of the device.In this example, a socket receiving section 661 is formed on the second case cover 66, and an inclined guide plate 621 is formed on the lower edge of the opening of the wastewater receiving section 62. The guide plate 621 guides wastewater and / or particulate contaminants into the wastewater receiving section 62. In this example, decorative plates are attached to the top and bottom of the support frame body 61 to improve appearance.

[0055] Preferably, as shown in FIG. 33 , a first toothed comb 67 is mounted on the support frame body 61, and the first toothed comb 67 is mounted between the wastewater storage compartment 62 and the pressure roller storage compartment 63. The first toothed comb 67 can be made of metal, plastic, or other materials. In this embodiment, a first brush storage compartment can be further formed on the support frame body 61. The first brush storage compartment is formed between the wastewater storage compartment 62 and the pressure roller storage compartment 63, and a brush is rotatably mounted within the first brush storage compartment. Specifically, one end of the brush is rotatably mounted on the first case cover 65, and the other end of the brush is rotatably mounted on the second case cover 66. The first toothed comb and the brush can also be mounted simultaneously in the cleaning device of the present invention. When the first toothed comb and / or brush are mounted, the rack or brush bristles and the rolling brush make point-to-surface contact. Conventional wiper blades or pressure rods and rolling brushes make surface-to-surface contact. When soft contaminants such as hair or noodles adhere to the rolling brush, the wiper blade or pressure rod is in surface-to-surface contact with the rolling brush, which prevents the wiper blade or pressure rod from removing the soft contaminants, and the soft contaminants may adhere more firmly to the rolling brush. When a first toothed comb and / or brush that makes point-to-surface contact is used, the rack or brush hairs on the first toothed comb and / or brush can effectively remove soft contaminants adhering to the rolling brush. Effectively removing soft contaminants from the rolling brush improves the efficiency of soft contaminant removal and allows for a cleaner cleaning of the ground.

[0056] When the pressure roller module 3 and the rolling brush 1 rotate in abutting contact state, water may collect below the roller module 3. In this case, the first toothed comb and / or brush guides the large amount of accumulated water into the wastewater storage section 62, thereby preventing the accumulated water from splashing in various places and leaving a large amount of water on the ground.

[0057] Preferably, as shown in FIG. 33 , a second toothed comb 68 is mounted on the support frame body 61, and the second toothed comb 68 is mounted on one side of the pressure roller housing 63, away from the wastewater storage section 62. The number of second toothed combs 68 may be one or more. When the number of second toothed combs 68 is more than one, the racks of each second toothed comb 68 are arranged so as to be offset from each other. In this embodiment, the number of second toothed combs 68 is two. In this embodiment, at least one second brush housing may be further formed on the support frame body 61. The second brush housing is formed on one side of the pressure roller housing 63, away from the wastewater storage section 62, and at least one brush is rotatably mounted in the second brush housing. The second toothed comb 68 and a brush may be simultaneously mounted in the cleaning device of the present invention. The brush in the second brush housing and the brush in the first brush housing may be the same or different.

[0058] After the pressure roller module 3 presses the rolling brush 1 to remove sewage and / or particulate contaminants from the rolling brush 1, the fleece absorbent layer on the surface of the rolling brush 1 abuts against the roller bearing, causing the fleece absorbent layer abutting the roller bearing to continue rotating in the forward direction. When the rolling brush 1 abuts against the ground, the fleece absorbent layer on the rolling brush 1 abuts against the ground, significantly reducing the rolling brush 1's ability to absorb sewage and / or particulate contaminants. As the pressure roller module 3 presses against the rolling brush 1, a second toothed comb 68 and / or brush abuts against the rolling brush 1 on the surface of the pressure roller module 3. The fleece absorbent layer is scrubbed with the rack or brush hairs, causing it to expand. The expanded fleece absorbent layer can effectively absorb sewage and / or particulate contaminants from the ground. As described above, the first toothed comb 67 and the second toothed comb 68 significantly improve the cleaning ability of the rolling brush 1.

[0059] As shown in FIGS. 1-2 and 36-37, a fixed part 69 is attached to one side of the support frame body 61 away from the rolling brush. The operating rod 8 is rotatably mounted on the fixed part 69 by a rotating structure, which includes a first rotating part 691 and a second rotating part 692. The forward movement direction of the cleaning device is defined as the positive x-direction, and the axial direction of the rolling brush is defined as the y-direction. The first rotating part 691 is arranged to rotate the operating rod 8 in the x-direction, and the second rotating part 692 is arranged to rotate the operating rod 8 in the y-direction. The free end of the operating rod 8 is freely rotatable, improving the user's convenience when rotating the operating rod. As shown in FIG. 41, a positioning rib 6921 is formed on the operating rod 8, and a positioning engagement recess 695 is formed on the fixed part 69. When the operating rod 8 is set upright, the positioning rib 6921 is engaged with the positioning engagement recess 695. In this embodiment, the positioning rib 6921 is formed on one end of the second rotating part 692 facing the fixed part 69 and close to the rolling brush. When the operating rod 8 is set up vertically, the operating rod 8 cannot rotate forward or left or right, so the user does not need to hold the operating rod 8 tightly all the time.

[0060] 36 and 38, the wastewater tank 71 is detachably mounted on one side of the support frame body 61 away from the rolling brush. In this example, the wastewater tank 71 is detachably mounted on a fixing part 69. An extension plate 693 is formed on the fixing part 69, and the extension plate 693 extends in a direction away from the support frame body 61. Elastic coupling protrusions 6931 are formed on both sides of the extension plate 693, and a coupling recess 712 corresponding to the elastic coupling protrusions 6931 is formed on the wastewater tank 71. The elastic coupling protrusions 6931 are coupled within the coupling recess 712. Preferably, one side wall of the coupling recess 712 approaching the support frame 61 is an inclined surface, and one end of the inclined surface approaching the opening of the coupling recess 712 is inclined toward the support frame. Since one side wall of the coupling recess 712 is an inclined surface, the elastic coupling protrusion 6931 can be easily coupled to or removed from the coupling recess 712. A filtering structure can be further installed in the wastewater tank 71. By filtering contaminants with the filtering structure, wastewater and / or particulate contaminants can be separated and solid contaminants can be easily removed. Water can be saved by returning the water filtered by the filtering structure to the fresh water tank 72.

[0061] As shown in Figures 36 and 37, a release button 694 is rotatably mounted on the fixed part 69. The release button 694 includes a push plate 6941 and an unlocking plate 6942 connected perpendicularly to the push plate 6941. The push plate 6941 extends in a direction away from the support frame body 61, and the push plate 6941 and the extending plate 693 are arranged parallel to each other. The unlocking plate 6942 is formed on one side of the wastewater tank 71 that is closest to the support frame body 61. Preferably, the push plate 6941 and the unlocking plate 6942 are molded integrally. When the push plate 6941 is pulled up, the unlocking plate 6942 pushes the wastewater tank 71 in a direction away from the support frame body 61, thereby allowing the wastewater tank 71 to come out of the support frame body 61. Preferably, a connecting block 6943 is formed on the push plate 6941, and a second connecting recess 713 corresponding to the connecting block 6943 is formed on the wastewater tank 71. When the wastewater tank 71 is mounted on the support frame body 61, the connecting block 6943 is fitted into the second connecting recess 713. In this embodiment, the connecting recess 712 is formed on the bottom of the wastewater tank 71, and the second connecting recess 713 is formed on the top of the wastewater tank 71. The connecting structures formed on the top and bottom of the wastewater tank 71 allow the wastewater tank 71 to be stably mounted on the support frame 6, thereby increasing the stability and durability of the wastewater tank 71 mounted on the support frame 6. The wastewater tank 71 can be easily mounted by connecting the wastewater tank 71 to the fixing part 69 of the support frame 6. A detachment button 694 is provided, and the wastewater tank 71 can be easily removed by rotating the detachment button 694. This makes it possible to easily remove wastewater and contaminants from the wastewater tank 71 or to easily clean the wastewater tank 71. Even a woman with weak strength can easily remove the wastewater tank 71, improving convenience in use.

[0062] As shown in FIG. 1 , the cleaning device of the present invention further includes a fresh water tank 72. The fresh water tank 72 supplies fresh water used for cleaning the rolling brush. The fresh water tank 72 includes a fresh water tank outlet, which is formed at the bottom of the fresh water tank 72. Preferably, the fresh water tank 72 is mounted on the operating rod 8. A tank connecting structure 81 and a sliding connecting structure 82 are mounted on the operating rod 8, and the sliding connecting structure 82 is mounted above the tank connecting structure 81. The sliding connecting structure 82 can slide on the operating rod 8. The bottom of the fresh water tank 72 is mounted on the tank connecting structure 81. The fresh water tank 72 is mounted on the operating rod 8 by the sliding connecting structure 82. The sliding connecting structure slides along the operating rod 8, allowing various fresh water tanks 72 with different volumes to be mounted on the operating rod 8. A tank connection port is formed on the tank connection structure 81, which is connected in communication with the fresh water tank outlet. The fresh water tank 72 can deliver fresh water to the surface of the rolling brush through the fresh water tank outlet, tank connection port, and launch pipe. An outlet valve is installed on one end of the fresh water tank 72 close to the fresh water tank outlet. When the fresh water tank 72 is removed or installed, the outlet valve prevents fresh water from the fresh water tank from flowing out of the fresh water tank outlet. Because the cleaning device of the present invention is equipped with a fresh water tank 72, the fresh water in the fresh water tank 72 can be used to clean the rolling brush when removing sewage and contaminants with the rolling brush. This realizes the automatic cleaning function of the rolling brush and allows for more thorough cleaning of the surface. In addition, a sliding connection structure allows various fresh water tanks 72 with different volumes to be installed on the operating rod, improving convenience.

[0063] 31, the cleaning device of the present invention further includes a pump 73. The pump 73 is connected to a fresh water tank 72 by a water pipe. 73The pump 73 can transport the fresh water in the fresh water tank 72 into the wiping device, that is, onto the surface of the rolling brush 1. In the present embodiment, the pump 73 is mounted in the support frame 6.

[0064] Preferably, as shown in FIGS. 30 and 31 , the pump 73, the circuit board 52, and the energy storage unit 53 are mounted on a pump energy storage device 5. The pump energy storage device 5 is detachably mounted in the integrated component storage section 64 of the support frame 6. The pump energy storage device 5 includes an integrated support frame 51, a pump 73, a circuit board 52, and an energy storage unit 53. The pump 73, the circuit board 52, and the energy storage unit 53 are all detachably mounted on the integrated support frame 51. The pump 73 is electrically connected to the circuit board 52, and the energy storage unit 53 is electrically connected to the circuit board 52 to supply power to the circuit board 52. The circuit board 52 supplies power to the entire cleaning device, for example, to the pump, the impeller driving motor, and the internal driving structure of the rolling brush. In an example of the present invention, the energy storage unit 53 includes at least two storage batteries, which are electrically connected in series or parallel.

[0065] The integrated support frame 51 includes a pump support frame 511 and a battery support frame 512 detachably connected to the pump support frame 511. The pump 73 is mounted in the pump support frame 511, a battery storage compartment is formed on the battery support frame 512, and the energy storage unit 53 is mounted in the battery storage compartment. In this embodiment, the circuit board 52 is mounted on the battery support frame 512, and the pump support frame 511 and the battery support frame 512 are connected by a connecting means.

[0066] A charging port 521 is mounted on the circuit board 52. The energy storage unit 53 can be charged by electrically connecting an external power source to the charging port 521. Preferably, the charging port 521 is a Type-C charging port. In this example, the charging port 521 is mounted on one side of the circuit board 52 that is remote from the pump 73.

[0067] The circuit board 52 is mounted with a pump control module, a power discharge protection module, a fast charging module, and an overall device control module. The pump control module controls the opening and closing of the pump and the flow rate. The power discharge protection module prevents overcharging, over-discharging, or overcurrent / overvoltage charging or discharging of the energy storage unit 53 when charging or discharging. The charging port 521 and fast charging module enable fast charging of the energy storage unit 53. The overall device control module controls the opening and closing of the cleaning device and other functions, thereby protecting the energy storage unit 53, reducing the risk of device damage, and extending the device's lifespan. In this embodiment, a display window is formed in the integrated component storage unit 64 at a position corresponding to the circuit board 52, and a display panel 522 is mounted within the display window. As shown in FIG. 2, the display panel 522 is electrically connected to the circuit board 52 and can display the operating status of the display device, battery information, cleaning mode, remote control information, etc. The display panel 522 is preferably a touch panel.

[0068] 5 and 6, the cleaning module includes a screw conveyor rod 21 and a wastewater storage unit 62. The screw conveyor rod 21 is attached so as to be close to or in contact with the rolling brush 1. A spiral convex portion 212 is formed on the screw conveyor rod 21. When the screw conveyor rod 21 rotates, the spiral convex portion 212 can transport wastewater and / or particulate contaminants from one end of the screw conveyor rod 21 to the other end. The spiral convex portion 212 can be a flexible convex portion or a rigid convex portion.

[0069] As shown in Figures 26 to 29, an impeller device 20 is attached to one end of the screw conveyor rod 21 in the transport direction. The screw conveyor rod 21 is rotatably attached inside the wastewater storage section 62, one end of the screw conveyor rod 21 is attached on the first case lid 65, and the other end of the screw conveyor rod 21 is rotatably attached on the impeller device 20. The impeller device 20 is detachably attached inside the second case lid 66, and the impeller device 20 is attached to the wastewater tank 71 The screw conveyor rod 21 transports the wastewater and / or particulate contaminants on the rolling brush 1 to the impeller device 20, and the impeller device 20 can send the wastewater and / or particulate contaminants by centrifugal force.

[0070] The impeller device 20 includes an impeller 22 and an impeller case 23, and the impeller 22 is rotatably mounted in the impeller case 23. An impeller housing 231, an impeller case water inlet 232, and an impeller case water outlet 233 are formed on the impeller case 23. The impeller case water inlet 232 and the impeller case water outlet 233 are both connected to the impeller housing 231. The impeller case water inlet 232 is formed on one side of the impeller case 23 close to the screw conveyor rod 21, and the impeller housing 231 is connected to the wastewater housing 62 through the impeller case water inlet 232, and the impeller case water outlet 233 is connected to a wastewater tank. 71The impeller 22 transfers the wastewater and / or particulate contaminants transported to the water inlet 232 of the impeller case to the wastewater tank through the water outlet 233 of the impeller case. 71 In the impeller housing 231, centrifugal force is applied to the wastewater and / or particulate contaminants by the rotation of the impeller 22, and the wastewater and / or particulate contaminants can be sent into the wastewater tank 71 by the centrifugal force. In the example of the present invention, the impeller housing 231 is a circular housing, the impeller case 23 is a circular case, and the water outlet 233 of the impeller case is formed on the surface of the impeller case 23 and is formed to protrude from the impeller case 23.

[0071] An impeller driving motor 234 is connected to the impeller 22, and the impeller driving motor 234 drives the impeller 22 to rotate. The installation of the impeller driving motor 234 makes it possible to control the rotation speed of the impeller 22. The rotation speed of the impeller 22 and the rotation speed of the screw conveyor rod 21 may be the same or different from each other. The impeller 22 rotates at a high speed by driving the impeller driving motor 234, thereby improving the efficiency of discharging wastewater and / or particulate pollutants.

[0072] A rotatable annular meshing recess is formed on the first case cover 65, and a screw meshing tooth 213 corresponding to the annular meshing recess is formed on one end of the screw conveyor rod 21 remote from the impeller device 20. The inclination direction of the annular meshing recess coincides with the rotation direction of the screw conveyor rod 21. When the screw conveyor rod 21 rotates, a force is applied to the screw conveyor rod 21 toward the first case cover 65, so there is no risk of the screw conveyor rod 21 falling off the second case cover 66 while rotating. An impeller device mounting hole penetrating the second case cover 66 is formed in the second case cover, and the screw conveyor rod 21 and the impeller device 20 can be attached through the impeller device mounting hole. The screw conveyor rod 21 is housed in the wastewater storage section 62, and the impeller device 20 is housed in the impeller device mounting hole. When the screw conveyor rod 21 rotates, a force is applied to the screw conveyor rod 21 toward the first case cover 65. Therefore, by attaching a mounting hole cover to the impeller device mounting hole, it is possible to prevent the screw conveyor rod 21 and the impeller device 20 from falling out of the impeller device mounting hole.

[0073] The other end of the screw conveyor rod 21 is rotatably mounted on an impeller case 23. A screw housing portion 237 is formed on the impeller case 23, and the other end of the screw conveyor rod 21 is rotatably mounted in the screw housing portion 237 by a bearing. The screw conveyor rod 21 and the impeller 22 may be disposed simultaneously or with their axes offset from each other.

[0074] In this embodiment, the impeller 22 and the impeller driving motor 234 are both installed in the impeller housing 231, and a driving motor housing 2311 is formed at the bottom of the impeller housing 231. The impeller driving motor 234 is housed in the driving motor housing 2311, and a driving motor housing cover 2312 is hermetically attached to the driving motor housing 2311. The impeller driving motor 234 includes a driving shaft 2341, which passes through the driving motor housing cover 2312 and is inserted into the impeller housing 231, and the impeller 22 is installed on the driving shaft 2341. An annular sealing recess 2313 is formed on the wall of the drive motor housing 2311, the drive motor housing 2311 and the annular sealing recess 2313 are arranged coaxially, a second sealing ring is installed in the annular sealing recess 2313, and the drive motor housing cover 2312 is detachably installed in the annular sealing recess 2313 in a sealed state. Since the impeller drive motor 234 is housed in the drive motor housing 2311 in a sealed state, it is possible to prevent water from inside the impeller housing 231 from flowing into the drive motor housing 2311 and damaging the impeller drive motor 234.

[0075] An installation opening 235 is formed on the impeller case 23, and a lid 236 is attached to the installation opening 235 in a sealed state. A first sealing ring is attached to the side wall of the lid 236, and the lid 236 is attached to the installation opening 235 in a sealed state by the first sealing ring. This seals the impeller case 23, preventing damage to the cleaning device due to leakage of water from the impeller housing part 231.

[0076] The impeller 22 includes an impeller body 221 and a plurality of blades 222 annularly mounted on the surface of the impeller shaft. A mounting recess 223 is formed on the impeller body 221, and the impeller body 221 is rotatably mounted in the annular sealing recess 2313 through the mounting recess 223. A support recess is formed on the cover 236, and a support rod 224 is formed on one side of the impeller 22 away from the mounting recess 223, and the support rod 224 is rotatably coupled within the support recess. In this embodiment, the support rod 224 is rotatably coupled within the support recess by a bearing.

[0077] The screw conveyor rod 21 is rotatably mounted in the wastewater storage section 62, and the screw conveyor rod 21 and the wastewater storage section 62 are arranged coaxially. The wastewater storage section 62 is an arc-shaped storage section, and the screw conveyor rod 21 is mounted so as to be close to or abut against the inner wall of the wastewater storage section 62. The opening of the wastewater storage section 62 faces the rolling brush 1, and the screw conveyor rod 21 is mounted so as to be close to or abut against the rolling brush 1. The wastewater and / or particulate contaminants on the rolling brush 1 are sent into the wastewater storage section 62.

[0078] In the wastewater storage section 62, an included angle θ is formed between the upper and lower edges of the opening of the wastewater storage section 62. That is, the wastewater storage section 62 is formed to surround the included angle θ. The included angle θ is greater than 180°, and the wastewater storage section 62 is attached so as to be close to or abut the rolling brush 1. A preferred range of the included angle θ is 180° to 270°. A more preferred included angle θ is 270°. By appropriately designing the included angle θ, the wastewater storage section 62 can fully surround the rolling brush 1. This ensures that wastewater and / or particulate contaminants on the rolling brush 1 enter the wastewater storage section 62 and prevents the wastewater and / or particulate contaminants from overflowing. In addition, by increasing the angle θ at which the wastewater storage section 62 surrounds the rolling brush 1, the completeness of the transport path of the screw conveyor rod 21 is ensured, and the screw conveyor rod 21 can transport more wastewater and / or particulate contaminants to the impeller device 20 or the wastewater tank 71.

[0079] The screw conveyor rod 21 includes a rod-shaped main shaft 211 and a spiral convex portion 212 formed in a spiral shape on the main shaft 211, and the spiral convex portion 212 can be a flexible convex portion or a rigid convex portion. A spiral recess 214 is formed between two adjacent spiral convex portions 212, and the spiral recess can transport wastewater and / or particulate contaminants in a predetermined direction. The spiral direction of the spiral convex portion 212 can be appropriately adjusted depending on the rotation direction of the screw conveyor rod 21 and the transport direction (of the contaminants).

[0080] The screw conveyor rod 21 is detachably mounted in the wastewater storage section 62, and the screw conveyor rod 21 is mounted close to or in contact with the inner wall of the wastewater storage section 62, so that the screw conveyor rod 21 can effectively transport wastewater and / or particulate contaminants. The screw conveyor rod 21 has a spiral recess thereon. 214The wastewater and / or particulate contaminants are transported to the impeller device 20 by the screw conveyor rod 21. In an example of the present invention, the distance between the screw conveyor rod 21 and the inner wall of the wastewater storage section 62 is 1 cm or less. Preferably, the distance between the screw conveyor rod 21 and the inner wall of the wastewater storage section 62 is 0.5 cm or less. More preferably, the distance between the screw conveyor rod 21 and the inner wall of the wastewater storage section 62 is 0.2 cm or less.

[0081] The screw conveyor rod 21 is attached so as to be close to or in contact with the rolling brush 1. In an embodiment of the present invention, the screw conveyor rod 21 is attached so as to be in contact with the rolling brush 1, and the screw conveyor rod 21 does not rotate together with the rolling brush 1. A driving part is connected to the screw conveyor rod 21, and the driving part drives the screw conveyor rod 21 to rotate. The screw conveyor rod 21 transports only wastewater and / or particulate contaminants, and the wastewater and / or particulate contaminants on the rolling brush 1 are sent into the wastewater storage section 62. The screw conveyor rod 21 transports the wastewater and / or particulate contaminants on the rolling brush 1 to the impeller device 20, and the wastewater and / or particulate contaminants are sent to the wastewater tank by the high-speed rotation of the impeller 22. 71In another embodiment of the present invention, the screw conveyor rod 21 is attached close to the rolling brush 1. The screw conveyor rod 21 transports the wastewater and / or particulate contaminants on the rolling brush 1 to the impeller device 20 side of the screw conveyor rod 21, and transports fresh water through the wastewater storage section 62. The fresh water is transported by the rotation of the screw conveyor rod 21, and is sent to the surface of the rolling brush 1 to clean the rolling brush 1. In addition, the screw conveyor rod 21 presses the rolling brush 1, squeezing out the water in the rolling brush 1 and effectively removing the contaminants on the rolling brush 1. The screw conveyor rod 21 transports the wastewater and / or particulate contaminants through the spiral recess 214, and squeezes out the wastewater and / or particulate contaminants on the rolling brush 1. In addition, the screw conveyor rod 21 can transport clean water to the surface of the rolling brush 1 to replace the dirty water on the rolling brush 1, thereby cleaning the rolling brush 1 and realizing automatic cleaning of the rolling brush 1. A user can select any one of the above functions or use a combination of multiple functions. When the screw conveyor rod 21 transports only dirty water and / or particulate contaminants, a clean water port facing the rolling brush 1 can be formed on the screw conveyor rod 21. Clean water in a clean water tank 72 is transported to the surface of the rolling brush 1 by a pump 73 and the clean water port.

[0082] The screw conveyor rod 21 is attached so as to be close to or in contact with the rolling brush 1, and the screw conveyor rod 21 and the rolling brush 1 rotate in opposite directions. The cylindrical screw conveyor rod 21 and the rolling brush 1 rotate in a contacting state, thereby reducing the resistance force applied to the rolling brush 1, reducing the risk of damage to the rolling brush 1, reducing the power required to drive the rolling brush 1, and reducing wear on the surfaces of the rolling brush 1 and the screw conveyor rod 21, thereby extending the life of the device.

[0083] The screw conveyor rod 21 has a spiral recess 214 formed thereon, thereby forming an uneven surface. When the screw conveyor rod 21 rotates while pushing the rolling brush 1, the uneven surface of the screw conveyor rod 21 rubs, taps, and pushes the soft clean layer on the surface of the rolling brush 1, thereby improving the cleaning and squeezing-out effects of the surface of the rolling brush 1. As the screw conveyor rod 21 pushes the rolling brush 1, it extrudes wastewater and / or particulate contaminants from the rolling brush 1, making the rolling brush 1 semi-wet, slightly wet, or slightly dry. This improves the automatic cleaning and squeezing-out effects of the rolling brush 1. The wet rolling brush 1 is used to wipe the ground to clean it, and the dirty water on the screw conveyor rod 21 and the rolling brush 1 is replaced with fresh water to send the dirty water and / or particulate contaminants into the dirty water tank 71, realizing automatic cleaning of the rolling brush 1 and simplifying the structure of the cleaning device, which in turn simplifies the device structure and reduces manufacturing costs.

[0084] A plurality of bristle brushes are attached to the screw conveyor rod 21, and the bristle brushes are attached to the spiral recess 214 and / or the spiral protrusion 212. Preferably, the bristle brushes are attached to the spiral protrusion 212. The bristle brushes improve the friction between the screw conveyor rod 21 and the rolling brush 1, and can prevent the screw conveyor rod 21 from sliding and not rotating together with the rolling brush 1. Preferably, the screw conveyor rod 21 is a shaftless screw conveyor rod.

[0085] The rolling brush 1 is attached to one side of the support frame 6 close to the wastewater storage section 62, and the rolling brush 1 comes into contact with the ground to remove wastewater and / or particulate contaminants on the ground. One end of the support frame body 61 extends to the top of the rolling brush 1, and the other end of the support frame body 61 extends to one side of the rolling brush 1 close to the bottom. The support frame body 61 prevents wastewater and / or particulate contaminants on the rolling brush 1 from overflowing. In this example, one end of the rolling brush 1 is rotatably attached to a first case cover 65.

[0086] The rolling brush 1 is a rolling brush with a drive structure attached thereto. A detachable part 4 is attached to one end of the rolling brush 1, and the rolling brush 1 and the detachable part 4 form a rolling brush module 10. As shown in Figures 7 to 25, the rolling brush 1 includes a rolling brush body 11 and a drive structure 12. A storage space 111 is formed in the rolling brush body 11, and an opening is formed at at least one end of the storage space 111. The drive structure 12 is stored in the storage space 111, and an end cover is attached to the opening of the rolling brush body 11 in a sealed state. Preferably, the drive structure 12 does not rotate together with the rolling brush body 11.

[0087] In this embodiment of the present invention, as shown in FIG. 7 , the rolling brush body 11 includes a roller bearing 13 and a flexible cleaning layer attached to the roller bearing, and the storage space 111 is formed within the roller bearing 13. Openings are formed at both ends of the roller bearing 13, respectively, designated as a first opening and a second opening. The rolling brush body 11 further includes a first end cap 112 and a second end cap 113, with the first end cap 112 attached to the first opening and the second end cap 113 attached to the second opening. Preferably, sealing rings are attached to the first and second openings, and the first end cap 112 is hermetically attached to the first opening and the second end cap 113 is hermetically attached to the second opening. The first and second end caps 112 and 113 are hermetically attached to the first and second openings, respectively, to prevent water from entering the driving structure of the rolling brush 1.

[0088] The rolling brush 1 is a water-absorbent rolling brush that is rotatably mounted on a cleaning device. There are generally two types of rolling brushes. The first is a water-absorbent wool-based rolling brush, and the second is a water-absorbent collodion-based rolling brush. A commonly used collodion is polyvinyl alcohol. The flexible cleaning layer can be a fleece water-absorbent layer or a water-absorbent rubber layer, but it can also be made of other water-absorbent materials.

[0089] As shown in FIG. 10 , the driving structure 12 includes a rotating shaft 121, and drives the rotating shaft 121 to rotate. A ring gear 122 is mounted on the rotating shaft 121, and a toothed recess 1311 is mounted within the roller bearing, and the toothed recess 1311 is mounted to correspond to the ring gear 122. The ring gear 122 is coupled to the toothed recess 1311, and the driving structure 12 drives the rolling brush body 11 to rotate via the ring gear 122 and the toothed recess 1311. In an embodiment of the present invention, the toothed recess 1311 is mounted within the receiving space 111. In an embodiment of the present invention, as shown in FIG. 15 , a fixing frame 131 is fixed within the receiving space 111, and the fixing frame 131 is fixed to the inner wall of the roller bearing 13, and the toothed recess 1311 is mounted on the fixing frame 131. Preferably, the fixing frame 131 and the roller bearing 13 are integrally molded.

[0090] 12 , the first end cover 112 is fixed to the inner wall of the roller bearing 13. The first end cover 112 has a first annular protrusion 1120, at least one coupling portion 1121 formed on the surface of the first annular protrusion 1120, and at least one positioning recess 132 formed on the inner wall of the roller bearing 13 near the second opening. The positioning recess 132 is formed to correspond to the coupling portion 1121, and the coupling portion 1121 is coupled within the positioning recess 132. The positioning recess 132 includes a first positioning recess 133 and a second positioning recess 134, which are connected to each other. The axial direction of the first positioning recess 133 overlaps with the axial direction of the roller bearing 13, and the axial direction of the second positioning recess 134 is perpendicular to the axial direction of the roller bearing 13. The first positioning recess 133 extends from the second opening along the inner wall of the roller bearing 13 to the position of the second positioning recess 134, thereby communicating with the second positioning recess 134. When installing the first end cover 112, the first end cover 112 is slid along the first positioning recess 133. When the first end cover 112 reaches the position of the second positioning recess 134, the first end cover 112 is rotated to engage the coupling portion 1121 into the second positioning recess 134. After the first end cover 112 is detachably coupled to the roller bearing 13, it can only be removed using a special tool. This improves safety and prevents the drive mechanism from falling off the roller bearing 13 due to incorrect opening of the first end cover 112.

[0091] As shown in FIG. 12 , a detachable part 4 is attached to one end of the rolling brush 1. The detachable part 4 allows the drive structure 12 to be removed by removing the first end cap 112, thereby making it easy to clean or replace the rolling brush body 11. As shown in FIG. 12 , the first end cap 112 is hermetically attached to the first opening of the rolling brush body 11, and the detachable part 4 penetrates the first end cap 112 and is fixed to the drive structure 12. The detachable part 4 allows the first end cap 112 and the drive structure 12 to be removed from the rolling brush body 11. The first end cap 112 can rotate together with the rolling brush body 11. The detachable part 4 serves to support the drive structure 12, and the detachable part 4 is fixed to the drive structure 12. Because the drive structure 12 is fixed to the detachable part 4, the drive structure 12 rotates together with the detachable part 4, but not together with the rolling brush body 11.

[0092] In this example, as shown in Fig. 16, a through-hole 1122 is formed on the first end cover 112 and penetrates the first end cover. As shown in Fig. 10, the detachable part 4 is attached to the drive structure 12 by the through-hole 1122. The detachable part 4 is attached to the drive structure 12 by a bolt. The detachable part 4 can also be attached to the drive structure 12 by other connecting means. The detachable part 4 does not rotate together with the rolling brush body 11. In this example, the bolt is a hollow bolt.

[0093] An unlocking recess 1123 is formed on the first end cover 112. In this example, a plurality of unlocking recesses 1123 are formed annularly on the surface of the first end cover 112, and the plurality of unlocking recesses 1123 are formed annularly around the through hole 1122.

[0094] 7 and 10, the driving structure 12 and the first end cap 112 are rotatably connected by a bearing 125. Neither the first end cap 112 nor the driving structure 12 rotates together with the rolling brush body 11.

[0095] 15 to 22, the detachable part 4 includes a case body 41 and a button 42. An insertion portion 421 is formed at one end of the button 42, and an elastically deforming recess 422 is formed at the end of the button 42 that is close to the insertion portion 421. The axial direction of the elastically deforming recess 422 is the same as the axial direction of the insertion portion 421. The elastically deforming recess 422 houses an elastically deforming structure.

[0096] The case body 41 is formed with a buttonhole 411 extending in the axial direction, and a through-type insertion hole 412 is formed at the bottom of the buttonhole 411. The inner diameter of the insertion hole 412 is smaller than that of the buttonhole 411, and the outer diameter of the insertion part 421 is not larger than that of the insertion hole 412. The height of the insertion part 421 is greater than that of the insertion hole 412, so that the insertion part 421 can be exposed to the outside beyond the insertion hole 412. A positioning pillar 413 is formed at the bottom of the buttonhole 411, and the height of the positioning pillar 413 is smaller than the depth of the elastic deformation recess 422. In this example, the elastic deformation structure is a spring 43, one end of which is attached to the positioning pillar 413 and the other end of which is housed in the elastic deformation recess 422. The position where the unpressed button is positioned in the buttonhole 411 is referred to as the initial position, and the position where the pressed button is positioned in the buttonhole 411 is referred to as the unlock position. The elastic deformation structure allows the button to be in the initial position when not pressed, and to be in the unlocked position when pressed.

[0097] The driving structure 12 can be electrically connected directly to the cleaning device via a conductor. In another embodiment, a conductive structure can be formed on the detachable part 4, and the detachable part 4 can be connected to an electric machine via a coupling means or a magnetic attraction means to supply power to the electric machine. Using such a detachable means allows for modularization of the device and facilitates the attachment and detachment of the rolling brush module 10. In this embodiment, the conductor of the driving structure 12 passes through a hollow bolt and extends into the detachable part 4. A waterproof electrical connection structure is formed on the detachable part 4, and the waterproof electrical connection structure is electrically connected to the circuit board of the support frame 6. The circuit board can then control the opening and closing and rotation speed of the driving structure 12.

[0098] One end of the rolling brush module 10 is electrically connected to the support frame via a waterproof socket in a waterproof manner. The waterproof socket includes a waterproof electrical connection structure and a waterproof locking structure. The detachable part 4 is provided with a waterproof electrical connection structure, and the support frame 6 is provided with a waterproof locking structure. In this embodiment, the case body 41 can be designed to be disassembled to facilitate easy installation and removal. As shown in FIG. 20 , the case body 41 is provided with a waterproof electrical connection structure, which includes at least one connection terminal and at least one electrical connection port 417. The connection terminal is fixed to the case body 41. In this embodiment, the case body 41 is formed with a connection terminal housing, and at least one connection terminal is housed in the connection terminal housing. The disassembly of the case body 41 allows the connection terminal to be easily installed in the connection terminal housing. The case body 41 is formed with at least one electrical connection port 417, which is configured to correspond to the connection terminal. 39-40, an elastic waterproof pad 418 is preferably attached between the electrical connection port 417 and the connection terminal, and the elastic waterproof pad 418 is attached to the electrical connection port 417 in a hermetically sealed state, with a caulking seam 4181 formed on the elastic waterproof pad 418. The electrical connection port 417, the caulking seam 4181, and the connection terminal are formed to correspond to each other. In this example of the present invention, the connection terminal is a female socket 416, and there are two female sockets 416. When a male plug is inserted into the female socket 416 via the electrical connection port 417 and the caulking seam 4181, the elastic waterproof pad 418 is attached hermetically around the male plug via the caulking seam 4181, so that water can be prevented from entering the female socket 416 via the caulking seam 4181. When the male plug is not inserted into the female socket 416, the caulking seam 4181 is sealed to prevent water from entering the female socket 416. As described above, the elastic waterproof pad 418 serves to provide waterproofing and sealing.Preferably, as shown in Figure 39, a V-shaped opening is formed on one side of the caulking seam 4181 that is closer to the electrical connection port 417. The longitudinal direction of the V-shaped opening is the same as the longitudinal direction of the caulking seam 4181, and the length of the V-shaped opening is the same as the length of the caulking seam 4181. The formation of the V-shaped opening makes it possible to easily insert a male plug into the caulking seam 4181 and prevents the caulking seam 4181 from being torn by the insertion of the male plug.

[0099] As shown in FIGS. 2-3 and 34-35, the waterproof socket further includes a waterproof locking structure 660. The waterproof locking structure 660 includes a plug body 662 and a male plug 663. A socket receiving portion 661 is formed in the second case cover 66 of the support frame, and the plug body 662 is fixed in the socket receiving portion 661. In this example, the plug body 662 is molded near the socket receiving portion 661 of the second case cover 66. An insertion recess 6621 is formed on the plug body 662, and at least one male plug 663 is fixed to the bottom of the insertion recess 6621, and the male plug 663 is fixed to correspond to the waterproof electrical connection structure. The male plug 663 is electrically connected to the female socket 416 via the electrical connection port 417 to supply power to the driving mechanism. In this example, there are two male plugs 663, and the other end of each male plug 663 is electrically connected to a circuit board.

[0100] An elastic hook portion 6622 and a hook coupling portion 6623 are formed on the side wall of the insertion recess 6621. One end of the elastic hook portion 6622 is fixed to the side wall of the insertion recess 6621, and the other end of the elastic hook portion 6622 is a free end that is not fixed. The hook coupling portion 6623 and the elastic hook portion 6622 are formed to correspond to each other, and the elastic hook portion 6622 can be coupled into the hook coupling portion 6623.

[0101] Preferably, an elastic sealing portion 6624 is attached within the hook coupling portion 6623. When the elastic hook portion 6622 is not pressed, it is in its initial position. The free end of the elastic hook portion is inserted into the insertion recess and the elastic hook portion is attached within the hook coupling portion, which is called the pressing position. When the elastic hook portion 6622 is pressed, it presses the elastic sealing portion 6624 and protrudes away from the insertion recess. When the pressing of the elastic hook portion 6622 is stopped, the elastic sealing portion 6624 deforms to its original shape, causing the elastic hook portion to return to its initial position.

[0102] An elastic hook is attached to the waterproof locking structure, and an elastic seal is attached within the hook connection. The elastic seal can prevent water from entering the cleaning device. When the waterproof electrical connection structure is removed, the elastic seal can move the elastic hook to its original position, protecting the waterproof electrical connection structure. Without the elastic deformation structure, if the cleaning device is not used for a long time, the elastic hook cannot return to its original shape and the elastic hook cannot be attached to the hook connection. The elastic deformation structure achieves a sealing effect and supports the elastic hook to return to its original shape, allowing the elastic hook to be used for a long time.

[0103] The detachable part 4 is formed with a fall-prevention structure, which can prevent the button 42 from falling off from the buttonhole 411. In the example of the present invention, a resilient stop 423 is formed on the surface of the button 42, and a protrusion 4231 is formed on the resilient stop 423. A stop recess 414 is formed on the inner wall of the buttonhole 411, and the protrusion 4231 is formed to correspond to the stop recess 414. When the button 42 is inserted into the buttonhole 411, the protrusion 4231 is fitted into the stop recess 414, preventing the button 42 from falling off from the buttonhole 411. In the axial direction of the button 42, the length of the buttonhole 411 is longer than the length of the protrusion 4231. In the example of the present invention, one side wall of the protrusion 4231 approaching the insertion part 421 is an inclined wall surface, which can easily fit the protrusion 4231 into the stop recess 414.

[0104] In this embodiment of the present invention, a coupling opening 424 is formed on the surface of the button 42, and a coupling protrusion 415 is formed on the inner wall of the buttonhole 411. When the button 42 is inserted into the buttonhole 411, the coupling protrusion 415 is coupled to the coupling opening 424. Preferably, the coupling opening 424 and the elastic stopper 423 are formed to face each other on both sides of the button 42. This improves the stability of the button 42 coupled to the buttonhole 411, allowing the button 42 to be inserted stably and smoothly into the buttonhole 411. In this example, the outer wall of the coupling opening 424 approaching the insertion portion 421 is an inclined surface, and one side wall of the coupling protrusion 415 away from the insertion hole 412 is an inclined side wall, thereby allowing the coupling protrusion 415 to be easily coupled to the coupling opening 424.

[0105] The coupling structure for coupling the button 42 into the buttonhole 411 is not limited to the above-mentioned coupling structure. Any structure may be used as long as it can prevent the button 42 from falling out of the buttonhole 411 and allows the insertion part 421 to be exposed to the outside when the button 42 is inserted into the buttonhole 411. In other embodiments, elastic stop parts 423 may be formed on both sides of the button 42 and stop recesses 414 may be formed on both sides of the buttonhole 411, or coupling openings 424 may be formed on both sides of the button 42 and coupling protrusions 415 may be formed on both sides of the buttonhole 411.

[0106] To install the button 42, one end of the spring 43 is fixed on the positioning post 413, and the button 42 is inserted into the button hole 411 and pressed into the button hole 411. When the button 42 is pressed into the button hole 411, the other end of the spring 43 is engaged in the elastically deforming recess 422. By continuing to press the button 42, the protrusion 4231 is engaged in the stop recess 414, and the engaging protrusion 415 is engaged in the coupling opening 424. In this case, due to the elastic force of the spring 43, the protrusion 4231 abuts against one side wall of the stop recess 414 that is away from the insertion hole 412, and one side wall of the coupling opening 424 that is close to the insertion portion 421 abuts against the engaging protrusion 415. The position where the button 42 is located at this time is defined as the initial position of the button 42.

[0107] When the button 42 is pressed, the protrusion 4231 moves within the stop recess 414, the coupling protrusion 415 remains coupled to the coupling opening 424, and the insertion portion 421 is exposed through the insertion hole 412. The position in which the button 42 is positioned within the button hole 411 is defined as the unlocking position of the button 42. At this time, the insertion portion 421 is inserted into the unlocking recess 1123. By pressing the button 42 and rotating the detachable part 4, the first end cover 112 is detached from the rolling brush body 11. The detachable part 4 is connected to the drive structure 12 through the first end cover 112, so that the detachable part 4, first end cover 112, and drive structure 12 can be detached together from the rolling brush body 11. Figure 6 shows the structure in which the detachable part 4, first end cover 112, and drive structure 12 have been removed. After the drive structure 12 is removed from the storage space 111, the button 42 can be released and moved to its initial position by the elastic force of the spring 23. In this embodiment, the first end cover 112 can be removed from the rolling brush body 11 by pressing the button 42 and rotating the detachable part 4. This provides a fool-proofing structure that prevents the button from moving to the unlocked position due to misoperation. Furthermore, if the detachable part is removed and the drive structure falls out of the storage space due to misoperation, the drive structure can be prevented from falling into water and being damaged.

[0108] In another embodiment of the present invention, as shown in FIGS. 10, 13-15, and 17, the rolling brush 1 is provided with a heat dissipation passage. This reduces the temperature of the electric motor and maintains high-speed operation. The present invention provides a heat dissipation passage in the rolling brush, which houses a drive mechanism. The heat dissipation passage allows the heat of the drive mechanism (i.e., the electric motor) within the rolling brush to be dissipated, thereby reducing the temperature of the electric motor and preventing it from burning out due to high temperatures. Furthermore, reducing the temperature of the electric motor increases the rotation speed of the electric motor, improving the cleaning speed and efficiency of the rolling brush and satisfying user needs. A large amount of heat is generated when the electric motor within the rolling brush operates. Because the electric motor is mounted within the rolling brush, it is not possible to effectively dissipate the heat from the electric motor. Therefore, the rotation speed of the electric motor within the rolling brush is typically set to 200-400 rpm. If the rotation speed of the electric motor is too high, the temperature of the electric motor will rise, potentially resulting in burnout. If the rotation speed of the motor is too low, the cleaning speed will be slow, reducing cleaning efficiency and failing to meet user requirements. To increase the rotation speed of the motor, the quality of the motor must be improved. For example, in a conventional cleaning device in which the motor is attached to the outside of the rolling brush, a motor with a rotation speed of 7000 rpm is attached to the outside of the rolling brush (to ensure operational stability), but the motor typically operates at a rotation speed of 1000 rpm. In a conventional cleaning device in which the motor is attached inside the rolling brush, the motor with a rotation speed of 7000 rpm typically operates at a rotation speed of 2400 rpm. While these two rolling brushes can meet user requirements, using a high-quality motor increases the manufacturing and operating costs of the cleaning device, making it unsuitable for mass use in ordinary households. The optimal way to ensure high-speed operation of the motor without increasing costs is to create a heat dissipation path in the rolling brush to dissipate heat from the motor, lower the temperature of the motor, and maintain high-speed operation.

[0109] 18 , the drive structure 12 includes a motor 123 and a motor case 124. The motor 123 includes a rotating shaft 121, and the motor 123 is housed in the motor case 124. The motor case 124 is fixed in the housing space 111, and does not rotate together with the rotating shaft 121 or the roller bearing 13. An exposure opening is formed at the position of the rotating shaft of the motor case 124, and the motor 123 is housed in the motor case 124. The rotating shaft 121 is exposed to the outside of the motor case 124 through the exposure opening. A ring gear 122 is mounted on the rotating shaft 121 exposed to the outside of the motor case 124, and the ring gear 122 is coupled to the toothed recess 1311. Preferably, the motor case 124 includes a first case 1241 and a second case 1242, and the first case 1241 and the second case 1242 can be coupled together.

[0110] The driving structure 12 is fixed in the receiving space 111, and the motor case 124 has at least one heat dissipation hole 1243 formed thereon, which is connected to a heat dissipation passage.

[0111] In this embodiment, as shown in FIG. 10 , a gap 14 is formed between the side wall of the motor case 124 and the inner wall of the roller bearing 13. The gap 14 is located within the receiving space 111, and the heat dissipation hole 1243 and the gap 14 are in communication with each other. As shown in FIG. 15 , at least one through-hole 1312 is formed on the fixing frame 131, and the through-hole 1312 and the gap 14 are in communication with each other. As shown in FIGS. 15 and 17 , at least one through-hole 1131 is formed on the second end cover 113, and the through-hole 1131 and the through-hole 1312 are in communication with each other. The heat dissipation path includes the gap 14 and the through-hole 1312, and the structure between the through-hole 1312 and the through-hole 1131 may be a solid structure or may form part of the receiving space 111. When the structure between the through hole 1312 and the through hole 1131 is a solid structure, an exhaust passage can be formed in the solid structure to connect the through hole 1312 and the through hole 1131. In the example of the present invention, a storage space 111 is formed between the through hole 1312 and the through hole 1131, and the through hole 1312 and the through hole 1131 are connected by the storage space 111.

[0112] When the motor operates, it releases heat. The heat from the motor is released to the heat dissipation path through the heat dissipation holes 1243. The heat dissipation path includes a through hole 1131 that passes through the gap 14, the through hole 1312, and the first end cover 112 in this order. The heat in the heat dissipation path can be released to the outside of the rolling brush 1 through the through hole 1131.

[0113] Preferably, the drive structure 12 is equipped with an exhaust device, which is mounted within the motor case 124. The exhaust device can quickly dissipate heat emitted by the motor and accumulated within the motor case 124, thereby quickly lowering the temperature of the motor. In other words, it can prevent the motor from rapidly rising in temperature. The exhaust device can be mounted inside or outside the motor. That is, the exhaust device and the motor can be assembled integrally or in a disassembled structure. The exhaust device can be mounted on one side of the rotating shaft away from the motor or on the rotating shaft of the motor. The exhaust device can be an exhaust fan or an exhaust impeller. Preferably, the exhaust device is mounted in the motor case 124 at a position close to the heat dissipation holes 1243. In an example of the present invention, the exhaust device is integrally assembled within the motor, and a plurality of motor heat dissipation holes 1231 are formed in a ring shape at the position where the exhaust device is mounted on the motor. The motor heat dissipation holes 1231 and the heat dissipation holes 1243 are formed to correspond to each other.

[0114] As shown in Figures 7, 10, and 13-14, water blocking cotton 15 is attached to the rolling brush body 11, and the waterproof cotton 15 is attached to correspond to the through-hole 1131. The waterproof cotton 15 is attached to the through-hole 1131 in a sealed state, thereby preventing water from entering the storage space 111 through the through-hole 1131. The waterproof cotton 15 may be attached to one side of the second end cover 113 that is close to the storage space 111, or to one side of the second end cover 113 that is away from the storage space 111. In this example, the waterproof cotton 15 is attached to one side of the second end cover 113 that is close to the storage space 111. The waterproof cotton 15 is attached, and the heat dissipation passage is sealed by the waterproof cotton 15. The waterproof property of the waterproof cotton 15 prevents water outside the rolling brush 1 from entering the drive structure through the heat dissipation passage. However, the waterproof cotton 15 does not affect the heat dissipation from the drive structure to the outside of the rolling brush 1 through the heat dissipation path.

[0115] Preferably, as shown in Figures 8, 10 and 13, a waterproof protrusion 1135 is formed on the end surface of the second end cover 113 remote from the storage space 111, and the height of the waterproof protrusion 1135 is higher than the height of the second end cover 113. The through hole 1131 is formed on the waterproof protrusion 1135 and extends in the longitudinal direction of the rolling brush 1. The height of the waterproof protrusion 1135 is higher than the height of the second end cover 113. A waterproof cover 115 is attached above the through hole 1131, and the waterproof cover 115 is detachably attached to the second end cover 113. In this example, the waterproof cover 115 is an arc-shaped waterproof cover that protrudes in a direction away from the rolling brush 1. The waterproof cover 115 is attached to the second end cover 113 with bolts. In this embodiment, the waterproof protrusion 1135 has an annular recess formed on its exterior, a positioning rib formed within the annular recess, and an open recess formed on the edge of the waterproof cover 115. When the waterproof cover 115 is attached to the second end cover 113, the open recess is engaged with the positioning rib, ensuring that the waterproof cover 115 and the second end cover 113 rotate together and preventing the waterproof cover 115 from falling off the second end cover 113 due to rotation. The waterproof cover 115 prevents water from entering the storage space 111 through the through-hole 1131. Furthermore, the height of the waterproof protrusion 1135 is higher than the height of the second end cover 113, preventing water from entering the through-hole 1131 even when the rolling brush 1 is placed vertically or horizontally. The waterproof cover 115, waterproof cotton, and waterproof protrusion 1135 significantly improve the waterproofness of the rolling brush 1.

[0116] 15, an inner cover 114 is attached to one end of the roller bearing 13 closest to the first opening. The inner cover 114 may be attached to one end of the roller bearing 13 closest to the first opening or may be housed on one side of the receiving space 111 closest to the second end cover 113. The second end cover 113 is rotatably attached to the inner wall of the roller bearing 13 or on the inner cover 114. The inner cover 114 may be detachably or non-detachably attached to one end of the roller bearing 13 closest to the first opening, or may be integrally formed with one end of the roller bearing 13 closest to the first opening. In this example, the inner cover 114 is non-detachably and hermetically fixed to one end of the roller bearing 13 closest to the first opening.

[0117] 13 , the second end cover 113 is rotatably mounted on the first opening, and a plurality of connecting hooks 1132 are formed in a ring shape on the second end cover 113. The axial direction of the connecting hooks 1132 is aligned with the axial direction of the rolling brush 1, and the plurality of connecting hooks 1132 are formed in a ring shape at intervals on the second end cover 113. An annular rib 1141 is formed on the inner wall of the roller bearing 13. When the second end cover 113 is mounted on the first opening, the connecting hooks 1132 are attached to the annular rib 1141. In this example, the inner cover 114 is a cylindrical cover with an opening formed at one end, the opening of the inner cover 114 facing the second end cover 113, and the annular rib 1141 is formed on the inner wall of the inner cover 114.

[0118] The rolling brush 1 is formed with an anti-jamming structure, which is formed on the inner cover 114 and the second end cover 113. When the rolling brush 1 cannot rotate due to an obstruction, the anti-jamming structure supports the driving mechanism, thereby protecting the motor. As shown in FIGS. 11 and 13, the inner cover 114 is formed with a connecting pin 1143, which extends in the radial direction of the roller bearing 13. A second annular protrusion 1133 is formed on one side of the second end cover 113, which is close to the connecting hook 1132. A plurality of grooves 1134 are formed on one end of the inner wall of the second annular protrusion 1133, which is close to the opening. The grooves 1134 are evenly distributed on the inner wall of the second annular protrusion 1133. The axial direction of the recessed groove 1134 and the axial direction of the second annular protrusion 1133 are aligned, the through hole 1131 is formed at the bottom of the second annular protrusion 1133, and the connecting pin 1143 is received in the recessed groove 1134. A plurality of recessed grooves 1134 are formed annularly on the inner cover 114, and the connecting pin 1143 is formed in the second end cover 113, and the connecting pin 1143 is fitted into the recessed groove 1134. In this example, the inner cover 114 is formed with the connecting pin 1143, and the second annular protrusion 1133 of the second end cover 113 is formed with a plurality of recessed grooves 1134 annularly.

[0119] The second annular protrusion 1133 is formed within an area surrounded by the multiple connecting hooks 1132, and multiple recessed grooves 1134 are formed on the inner wall of the second annular protrusion 1133. A pillar 1142 is formed on one side of the inner cover 114, which is closer to the second end cover 113, and the axis of the pillar 1142 is aligned with the axis of the roller bearing 13. Preferably, the pillar 1142 and the roller bearing 13 are arranged coaxially. At least one connecting pin 1143 is formed on the surface of the pillar 1142, and the connecting pin 1143 extends in the diameter direction of the pillar 1142. One end of the connecting pin 1143 is fixed on the pillar 1142, and the other end of the connecting pin 1143 is free. The connecting pin 1143 is received in the recessed groove 1134. Preferably, the free end of the connecting pin 1143 is inclined toward the pillar 1142, and the inclination direction of the connecting pin 1143 is opposite to the inclination direction of the rolling brush 1. Preferably, the free end of the connecting pin 1143 is a circular hole-shaped free end. In this example, a third annular protrusion 1144 is further formed on the inner cover 114, and the second annular protrusion 1133 protrudes into the third annular protrusion 1144. The second annular protrusion 1133 of the second end cover 113 protrudes and is housed in the third annular protrusion 1144. The second annular protrusion 1133 protruding into the third annular protrusion 1144 can play a role in supporting an anti-jamming structure.

[0120] When the cleaning device is in use, the driving structure 12 drives the rolling brush 1 to rotate, and the connecting pin 1143 is engaged with the recessed groove 1134, causing the inner cover 114 and the second end cover 113 to rotate together. The second end cover 113, the rolling brush body 11, or the first end cover 112 may be unable to rotate due to being obstructed by hair or other contaminants. The extension direction of the connecting pin 1143 and the rotation direction of the recessed groove 1134 are opposite, and the rotating connecting pin 1143 can be engaged in turn with the various recessed grooves 1134. When the driving structure prevents the connecting pin 1143 from rotating, the rotating connecting pin 1143 is engaged in turn with the various recessed grooves 1134. When the coupling pin 1143 is not engaged with the recessed groove 1134, the coupling pin 1143 is pressed, and when the coupling pin 1143 is engaged with the recessed groove 1134, the coupling pin 1143 returns to its original shape, making a "tatter" sound. This prevents overcurrent from being input to the motor, the motor's temperature from becoming too high, and damage to the motor or rolling brush. In addition, the cleaning device makes a "tatter" sound to notify the user that the rolling brush cannot rotate due to an obstruction and that contaminated areas near the rolling brush need to be removed. This prevents damage to the motor, odors, and fires.

[0121] At least one open pore 1145 is formed on the inner cover 114, and the open pore 1145 communicates with the through hole 1131. The open pore 1145 may communicate with the through hole 1312 via the receiving space 111 or an exhaust passage. In this example, waterproof cotton 15 is installed between the open pore 1145 and the through hole 1131, and the open pore 1145 communicates with the through hole 1312 from the receiving space 111. In this case, the motor 123 releases heat to the outside of the rolling brush 1, and the heat of the motor is released to the outside of the rolling brush 1 via the heat dissipation hole 1243, the gap 14, the through hole 1312, the receiving space 111 or the exhaust passage, the open pore 1145, and the through hole 1131.

[0122] In this embodiment of the present invention, the process of attaching the electric motor and the detachable parts of the rolling brush is as follows.

[0123] The first end cover is attached between the electric case and the detachable part, and the second case and the detachable part are connected by the hollow bolt. Next, the electric machine is housed in the first case, and the leads of the drive structure are inserted into the through holes of the hollow bolt, and then the second case is fitted onto the first case. Finally, the drive structure is fed into the housing space through the second opening, and the ring gear is fitted into the toothed recess. The first end cover is then rotated to fit into the second positioning recess on the inner wall of the roller bearing.

[0124] It should be noted that, unless contradictions arise, the technical features of the rolling brush module can be freely combined, and it is natural that such combinations, modifications, changes and improvements of technical features are included in the scope of the claims of the present invention.

[0125] The drive structure is mounted inside the rolling brush, which simplifies the structure, saves installation space, and reduces modules and volume, thereby making the device lighter, more portable, and simpler, and reducing manufacturing costs.

[0126] When the rolling brush is removed from the cleaning device, the drive structure mounted within the rolling brush can be removed together, improving ease of operation and use and preventing dirty water and / or particulate contaminants on the rolling brush from entering the drive structure, which could cause a short circuit in the drive structure's lines or damage the drive structure.The drive structure within the rolling brush is electrically connected to the device body, simplifying the structure, improving ease of use, and achieving an ingenious design, as well as facilitating installation and removal of the rolling brush.

[0127] When using the cleaning device, the rolling brush must be replaced regularly. By attaching or detaching the rolling brush and its internal drive mechanism together, the convenience of replacing the rolling brush is greatly improved. Furthermore, by attaching the rolling brush to the device body using a coupling means or a magnetic attraction means, the rolling brush can be easily replaced and the replacement process is more convenient. The drive mechanism within the rolling brush can be detached from the rolling brush. When replacing the rolling brush, the drive mechanism can be removed from the storage space 111 and then reattached to the new rolling brush. The new rolling brush with the attached drive mechanism can then be attached to the device body to complete the rolling brush replacement. When replacing the rolling brush, only the roller bearing with the attached flexible cleaning layer needs to be replaced, and the drive mechanism can be reused, thereby reducing operational costs. When the drive mechanism is damaged, only the drive mechanism can be replaced, eliminating the need to replace the entire cleaning device or rolling brush module.

[0128] As shown in FIG. 6 , the pressure roller module 3 is mounted on a support frame 6. Specifically, the pressure roller module 3 is mounted on one side of the rolling brush 1 closest to the cleaning module 2, and the pressure roller module 3 is located above the cleaning module 2. The pressure roller module 3 can be a conventional cylindrical pressure roller or a pressure roller module with balls attached. The cylindrical pressure roller has a concave and convex shape, and a gap is formed between two adjacent balls. The gap allows the pressure roller module 3 to effectively remove particulate contaminants and adhesive contaminants from the surface of the rolling brush 1. The axial direction of the pressure roller module 3 is aligned with the axial direction of the rolling brush 1. The pressure roller module 3 abuts against the rolling brush 1, and the pressure roller module 3 can push the sewage and / or particulate contaminants on the rolling brush 1. A driving component is connected to the pressure roller module 3, and the driving component can drive the pressure roller module 3 to rotate. Preferably, the rotation direction of the pressure roller module 3 is opposite to that of the rolling brush 1. In order to adjust the tightness of the pressure roller module 3 contacting the rolling brush 1, a tension spring or a compression spring can be attached.

[0129] The pressure roller module 3 is attached, and the pressure roller module 3 presses the rolling brush 1 to remove dirty water and / or particulate contaminants from the rolling brush 1. The removed dirty water and / or particulate contaminants go into the dirty water storage compartment 62 below the pressure roller module 3, preventing or reducing water residue on the ground after cleaning. This also further prevents particulate contaminants from adhering to the surface of the rolling brush 1. The ball of the rolling brush 1 presses the rolling brush 1 to squeeze out the dirty water inside the rolling brush 1 and remove particulate contaminants or adhesive contaminants. This makes the rolling brush 1 semi-wet, slightly wet, or slightly dry, improving the operating efficiency and cleaning effect of the rolling brush 1.

[0130] 42 to 47 show a wiping device according to another embodiment, which includes a rolling brush 1, a screw conveyor rod 21, an adjustment part 16 and a wastewater storage part 62.

[0131] The rolling brush 1 is rotatably mounted on the device case, and the screw conveyor rod 21 is rotatably mounted on the device case.

[0132] The screw conveyor rod 21 is attached to one side of the rolling brush 1, and the screw conveyor rod 21 abuts against the rolling brush 1 via an adjustment part 16. The adjustment part 16 controls the degree to which the screw conveyor rod 21 abuts against the rolling brush 1. The adjustment part 16 is an elastic tension structure having a certain elasticity, and the elastic tension structure may be a spring having a certain elasticity. In this example of the present invention, the adjustment part 16 is a spring, and one end of the spring is rotatably attached to the main shaft mounting part 215, and the other end of the spring is rotatably attached to the roller bearing 13. Preferably, the rotation direction of the screw conveyor rod 21 and the rotation direction of the rolling brush 1 are opposite to each other, so that the rotation resistance of the rolling brush 1 can be reduced.

[0133] The screw conveyor rod 21 pushes the rolling brush 1, thereby squeezing out the moisture from the rolling brush 1 and effectively removing the contaminants on the rolling brush 1.

[0134] The screw conveyor rod 21 is a strip-shaped component having a spiral recess 214 formed on its surface. The screw conveyor rod 21 includes a main shaft 211 and main shaft mounting portions 215 formed on both ends of the main shaft 211. At least one spiral recess 214 is formed on the surface of the main shaft 211, and the spiral recess 214 is formed in a spiral shape from one end of the screw conveyor rod 21 to the other. The spiral direction of the spiral protrusion 212 can be appropriately adjusted depending on the rotation direction of the screw conveyor rod 21 and the transport direction (of transporting contaminants). Since the spiral recess 214 is formed on the surface of the main shaft 211, the surface of the main shaft 211 has an uneven shape. A plurality of spiral recesses 214 can be formed on the surface of the main shaft 211. That is, a plurality of spiral recesses 214 are formed by a plurality of spiral structures.

[0135] In the present embodiment, the outer diameter of the spindle mounting portion 215 is smaller than the outer diameter of the spindle 211, and the spindle 211 and the spindle mounting portion 215 are integrally molded.

[0136] The rolling brush 1 is an absorbent rolling brush. Rolling brushes generally come in two varieties: absorbent wool-cotton rolling brushes and absorbent collodion rolling brushes. A commonly used collodion is polyvinyl alcohol. The rolling brush 1 includes a roller bearing 13, on which a flexible cleaning layer 130 is detachably attached. The flexible cleaning layer 130 can be a wool-cotton cleaning layer or an absorbent collodion cleaning layer, but it can also be made of other absorbent materials. When using conventional rolling brushes or mops, the rolling brushes or mops must be manually cleaned. While some rolling brushes or mops have an automatic cleaning function, they suffer from the drawback of poor cleaning efficiency.

[0137] The ground is cleaned by wiping it with the moistened rolling brush 1. Then, by replacing dirty water with fresh water on the screw conveyor rod 21 and the rotating rolling brush 1, the dirty water and / or particulate contaminants can be guided to a predetermined location by the semi-closed storage section. This allows the rolling brush 1 to have an automatic cleaning function, simplifies the structure, and helps simplify the device and reduce costs.

[0138] Preferably, the outer diameter of the rolling brush 1 is larger than that of the screw conveyor rod 21 .

[0139] Fixed plates 116 are attached to both ends of the roller bearing 13, and the fixed plates 116 are fixed to the device case. A plurality of fixing holes 1161 are formed in the fixed plates 116 in the radial direction. One end of the spring is connected to the fixing holes 1161. By connecting the springs to various fixing holes 1161, the degree of pressure on the screw conveyor rod 21 or the pressure roller module 3 can be controlled.

[0140] The wastewater storage section 62 is a semi-enclosed storage section. The screw conveyor rod 21 is installed within the semi-enclosed storage section of the wastewater storage section 62, and the screw conveyor rod 21 can rotate within the wastewater storage section 62. The main shaft 211 is installed so as to be close to or abut against the inner wall of the wastewater storage section 62. The wastewater storage section 62 is formed with a through-type wastewater contaminant guide port 623 extending in the water absorption direction of the screw conveyor rod 21. The screw conveyor rod 21 transports wastewater and / or particulate contaminants from one end of the screw conveyor rod to the other end of the screw conveyor rod, and the wastewater and / or particulate contaminants transported to the other end of the screw conveyor rod are discharged to the outside through the wastewater contaminant guide port 623. In this example, a through-type clean water inlet 624 is formed at the other end of the wastewater storage section 62, away from the wastewater contaminant guide port 623. In the present embodiment, both ends of the wastewater storage portion 62 are sealed, and the wastewater contaminant guide port 623 is formed on the side wall of the wastewater storage section 62.

[0141] A wastewater storage opening 622 is formed on one side of the wastewater storage compartment 62 facing the rolling brush 1, and a gap is formed between the lower edge of the wastewater storage opening 622 and the rolling brush 1. The rotating rolling brush 1 can use the gap to send wastewater and / or particulate contaminants to the screw conveyor rod 21. Preferably, the longitudinal direction of the wastewater storage opening 622 and the longitudinal direction of the wastewater storage compartment 62 coincide with each other, and the length of the wastewater storage opening 622 is shorter than the length of the rolling brush 1. The present invention is not limited to an embodiment in which the length of the wastewater storage opening 622 is shorter than the length of the rolling brush 1, and in other embodiments, the length of the wastewater storage opening 622 and the length of the rolling brush 1 may be the same.

[0142] The screw conveyor rod 21 operates on the following principle. The screw conveyor rod 21 pushes or abuts against the rolling brush 1, and the adjusting member 16 controls the degree to which the screw conveyor rod 21 pushes the rolling brush 1. When the screw conveyor rod 21 rotates, the uneven surface of the screw conveyor rod kneads, beats, and pushes the flexible cleaning layer 130 on the surface of the rolling brush 1, thereby squeezing out the wastewater and / or particulate contaminants on the rolling brush 1, and the squeezed out wastewater and / or particulate contaminants flow into the spiral recess 214 of the screw conveyor rod 21. As the screw conveyor rod 21 rotates, the wastewater and / or particulate contaminants in the spiral recess 214 are transported from one end of the screw conveyor rod 21 to the other.

[0143] Fresh water can also be supplied from one end of the screw conveyor rod 21. When the screw conveyor rod 21 rotates and pushes the rolling brushes 1, the fresh water is transported to the rolling brushes 1 that are in contact with the screw conveyor rod 21. This replaces the water on the rolling brushes 1, transporting the sewage and / or particulate contaminants on the rolling brushes 1 to the other end of the screw conveyor rod 21, and realizing automatic cleaning of the rolling brushes 1.

[0144] In a preferred embodiment of the present invention, the device further includes a pressure roller module 3. The addition of the pressure roller module 3 allows the rolling brush 1 to be pressed more firmly, thereby improving the effect of squeezing out water from the rolling brush 1 and preventing or reducing water remaining on the ground after cleaning. It also further prevents particulate contaminants from adhering to the surface of the rolling brush 1.

[0145] The pressure roller module 3 is rotatably mounted on an extension of the device case or the wastewater storage section 62. The pressure roller module 3 is mounted on the upper side of the screw conveyor rod 21 so as to press the rolling brush 1. Preferably, the outer diameter of the rolling brush 1 is larger than the outer diameter of the pressure roller module 3.

[0146] The adjustment part 16 can control the degree to which the pressure roller module 3 contacts the rolling brush 1. That is, the adjustment part 16 controls the degree to which the pressure roller module 3 presses the rolling brush 1. In the present embodiment, the adjustment part 16 that controls the degree to which the pressure roller module 3 presses the rolling brush 1 can also be a spring. For a method of attaching the spring (i.e., the adjustment part), refer to the method of connecting the spring between the screw conveyor rod 21 and the rolling brush 1.

[0147] When the pressure roller module 3 is further installed, a gap or hollow hole is further formed between the upper edge of the wastewater storage opening 622 and the rolling brush 1. The wastewater and / or particulate contaminants squeezed out by the pressure roller module 3 can be transported to the screw conveyor rod 21 through the gap or hollow hole.

[0148] The operating principle of the pressure roller module 3 is as follows. When the pressure roller module 3 is in contact with the rolling brush 1, the adjusting component 16 controls the degree to which the pressure roller module 3 presses against the rolling brush 1. When the pressure roller module 3 presses against the rolling brush 1 again to squeeze out the wastewater and / or particulate contaminants on the rolling brush 1, the squeezed out wastewater and / or particulate contaminants flow from the surface of the rolling brush 1 into the spiral recess 214 of the screw conveyor rod 21.

[0149] In this embodiment, the wiping device further includes a device case, in which the rolling brush 1, the screw conveyor rod 21, the pressure roller module 3, and the wastewater storage section 62 are all housed, with a portion of the rolling brush 1 exposed to the outside of the device case.

[0150] When the pressure roller module 3 is not installed, a baffle is installed on the upper part of the wastewater storage section so as to come into close contact with the rolling brush.

[0151] In an embodiment of the present invention, the mopping device for cleaning the ground further includes a driving device. The driving device is connected to the rolling brush 1 and drives the rolling brush 1 to rotate. The driving of the rotating rolling brush 1 causes the screw conveyor rod 21 to rotate in the opposite direction, and the rotation of the screw conveyor rod 21 can transport sewage and pollutants.

[0152] In an embodiment of the present invention, the rolling brush 1 can be connected to one driving device and the screw conveyor rod 21 can be connected to another driving device, in which case the rolling brush 1 and the screw conveyor rod 21 can be rotated by the driving of each driving device.

[0153] In an embodiment of the present invention, the driving device may not be attached to the rolling brush 1, but may be directly connected to the screw conveyor rod 21. In this case, the rolling brush 1 can be rotated in the opposite direction by the driving force of the rotating screw conveyor rod 21.

[0154] In an embodiment of the present invention, the rolling brush 1 and the screw conveyor rod 21 of the wiping device may not be provided with any driving devices. When using the wiping device, the rolling brush 1 rotates when the user moves the wiping device. In addition, the rotation of the rolling brush 1 causes the screw conveyor rod 21 to rotate in the opposite direction, and the rotation of the screw conveyor rod 21 can transport sewage and contaminants.

[0155] In the four embodiments relating to the driving device, when a pressure roller module is installed, one driving device may be further included, which is coupled to the pressure roller module and can drive the pressure roller module to rotate.

[0156] It should be noted that, provided that no contradiction arises, the technical features of each of the above-mentioned components may be freely combined, and it is natural that such combinations, modifications, changes, improvements, etc. of technical features are included within the scope of the claims of the present invention.
