[0034] The present disclosure provides a cleaning device, as shown in Figures 1 to 5. The cleaning device 10 includes: a device body 100, a first cleaning module 200, and a second cleaning module 300. The first cleaning module 200 is disposed on the device body 100 and includes a first cleaning head 210. When the first cleaning head 210 is in operation, a first cleaning area S1 is formed. The second cleaning module 300 is disposed on the device body 100 and includes a second cleaning head. When the second cleaning head is in operation, a second cleaning area S2 is formed. When the first cleaning module 200 and the second cleaning module 300 are in operation simultaneously, the first cleaning area S1 and the second cleaning area S2 at least partially overlap or have no overlapping portions.

[0035] The cleaning device 10 provided in the present disclosure has a first cleaning module 200 and a second cleaning module 300. When the first cleaning head 210 rotates, it can form a first cleaning area S1, and when the second cleaning head rotates, it can form a second cleaning area S2. The first cleaning area S1 and the second cleaning area S2 at least partially overlap or do not overlap, that is, the debris cleaned by one cleaning module 200 can be centrally processed by the other cleaning module 200, thereby improving the cleaning effect and cleaning effect of the cleaning device 10.

[0036] In one embodiment, the first cleaning module 200 comprises a drive assembly, a swing arm 220, and a first cleaning head 210. The first end of the swing arm 220 is rotatably mounted to the device body 100, and the swing arm 220 can be positioned between a retracted position and an extended position by swinging relative to the device body 100. The side brush is mounted on the second end of the swing arm 220. As shown in Figures 1 and 2, when the swing arm 220 is in the retracted position, the first cleaning area S1 and the second cleaning area S2 formed by the swing arm 220 and the first cleaning head 210 overlap.

[0037] 3 and 4 , when the swing arm 220 is in the extended position, the first cleaning area S1 and the second cleaning area S2 do not overlap. When the swing arm 220 is in the extended position, more cleaning areas are provided, improving the cleaning effect of the cleaning device 10.

[0038] The first cleaning head 210 may be a side brush that forms a circular first cleaning area S1 by rotating. As shown in Figure 6, the side brush includes a mounting portion 211 and multiple brush claws 212 connected to the mounting portion 211. The multiple brush claws 212 are rotatably mounted on the swing arm 220 via the mounting portion 211. The multiple brush claws 212 are of the same length and include three brush claws 212 evenly distributed around the circumference of the side brush to enhance cleaning effectiveness. Alternatively, the side brush may include two, four, or more brush claws 212.

[0039] The first end of the swing arm 220 is connected to the drive assembly. A gear train can be provided in the swing arm 220 to enable the output shaft of the drive assembly to drive the brush head to rotate at high speed. The brush head can rotate at a speed of 500 to 3000 rpm to improve cleaning efficiency and effectiveness. Examples of speeds include 500 rpm, 800 rpm, 1000 rpm, 2000 rpm, and 3000 rpm, which are not listed here. Of course, the brush head can also rotate at speeds less than 500 rpm or greater than 3000 rpm, which is not limited in this disclosure.

[0040] The swing arm 220 may have a receiving space formed therein to allow the gear set to be installed therein. The swing arm 220 may be shaped like a rectangular parallelepiped, with the swing arm 220 extending in its length direction. The swing arm 220 may swing in its width direction. The receiving space formed in the thickness direction of the swing arm 220 may only need to be able to accommodate the gear set, thereby preventing the swing arm 220 from being too large.

[0041] Among them, the swing arm 220 can be swung back and forth within a preset angle range through a driving component. The driving component that drives the swing arm 220 and the driving component that drives the brush head can be two independent driving components; or, the swing arm 220 is rotatably connected to the driving component, and the swing arm 220 is not driven by the driving component. The swing arm 220 can swing relative to the driving component through external force to change the position of the brush head relative to the shell.

[0042] Among them, the swing arm 220 swings back and forth within a preset angle range, and the preset angle can be 20°~120°, such as 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, etc., which are not listed one by one in this disclosure.

[0043] Among them, the swing arm 220 can be swung back and forth within a preset angle range through a driving component. The driving component that drives the swing arm 220 and the driving component that drives the brush head can be two independent driving components; or, the swing arm 220 is rotatably connected to the driving component, and the swing arm 220 is not driven by the driving component. The swing arm 220 can swing relative to the driving component through external force to change the position of the brush head relative to the device body 100.

[0044] In one embodiment, the second cleaning module 300 includes a negative pressure fan, a suction box, a suction channel, and a roller brush. The outlet of the suction channel is connected to the suction box, and the inlet of the suction channel is exposed from the cover plate. The negative pressure fan is connected to the suction box so that the suction box maintains a negative pressure state when the cleaning device 10 performs a cleaning operation, thereby maintaining a negative pressure state at the inlet of the suction channel. A roller brush that rotates around an axis parallel to the ground is provided at the suction port. The roller brush, which has a certain interference with the ground, sweeps up debris on the ground and rolls it into the suction channel. The debris is then sucked into the suction box by the suction gas generated by the negative pressure fan and passing through the suction box. The cleaning area corresponding to the roller brush forms the second cleaning area S2.

[0045] Among them, the brush head of the first cleaning module 200 is arranged adjacent to the roller brush. The brush head rotates at high speed to clean the debris to the vicinity of the roller brush. Then the roller brush sweeps up the debris and rolls it into the sewage suction channel. Due to the negative pressure, it is sucked into the sewage suction channel through the sewage suction port and then enters the sewage suction box, thereby completing the debris cleaning operation on the surface to be cleaned.

[0046] As shown in Figure 2, the roller brush is located in the middle of the bottom of the cleaning device 10, and the brush head is located in the front side of the roller brush, so that the debris swept by the brush head can basically be located in the cleaning area corresponding to the roller brush, so that the swept debris can better enter the sewage suction port.

[0047] Among them, the negative pressure provided by the negative pressure fan can be 3000Pa~7000Pa to enhance the negative pressure absorption effect of debris. The negative pressures are, for example, 3000Pa, 4000Pa, 5000Pa, 6000Pa, 7000Pa, etc., which are not listed one by one in this disclosure; of course, the negative pressure provided by the negative pressure fan can also be less than 3000Pa or greater than 7000Pa, which is not limited in this disclosure.

[0048] There can be two roller brushes, which rotate towards each other to sweep up the debris and roll it into the sewage suction channel.

[0049] In one embodiment, as shown in FIG2 , the first cleaning area S1 formed by the side brush is circular, and the second cleaning area S2 formed by the roller brush is rectangular. Because the side brush is positioned to the side and front of the roller brush in the direction of travel Z of the cleaning device 10, the overlapping portion of the first cleaning area S1 and the second cleaning area S2 is located at the corner of the second cleaning area S2 near the side brush. When the side brush sweeps debris toward the roller brush, the debris is essentially located in front of the roller brush, making it easier for the roller brush to sweep up the debris and carry it into the suction channel, thereby improving the cleaning effect.

[0050] In one embodiment, the drive module can manipulate the cleaning device 10 to travel across the ground in the forward direction Z based on a drive command with distance and angle information. The drive module can include a first drive wheel module and a second drive wheel module. The first drive wheel module and the second drive wheel module are arranged along the transverse axis defined by the cleaning device 10, and the extension direction of the transverse axis is the forward direction Z of the cleaning device 10. In order to enable the cleaning device 10 to move more stably or have stronger mobility on the ground, the cleaning device 10 may include one or more driven wheels, including but not limited to universal wheels. The drive wheel module includes a running wheel and a drive motor and a control circuit for controlling the drive motor. The drive wheel module can also be connected to a circuit and an odometer for measuring the drive current. The drive wheel module can be detachably connected to the bottom shell for convenient disassembly and maintenance. The drive wheel can have a biased drop-down suspension system, fastened in a movably manner, for example, attached in a rotatable manner, connected to the bottom shell, and receiving a spring bias that is biased downward and away from the bottom shell. The spring bias allows the drive wheel to maintain contact and traction with the ground with a certain ground force, while the cleaning head of the cleaning device 10 also contacts the ground with a certain pressure.

[0051] In one embodiment, as shown in FIG5 , the spacing between the end of the second cleaning head close to the first cleaning head 210 and the axis of symmetry of the cleaning device 10 in the second direction is x, and the spacing between the rotation axis of the swing arm 220 and the axis of symmetry of the cleaning device 10 in the second direction is y, where x is greater than y. The forward direction Z of the cleaning device 10 is the first direction, and the second direction is perpendicular to the first direction. By ensuring that the spacing x between the end of the second cleaning head close to the first cleaning head 210 and the axis of symmetry of the cleaning device 10 in the second direction is greater than the spacing y between the rotation axis of the swing arm 220 and the axis of symmetry of the cleaning device 10 in the second direction, that is, the swing arm 220 and the roller brush have an overlapping portion in the first direction, the cleaning effect can be improved.

[0052] Wherein, the ratio of (xy) to x is greater than or equal to 0.05 and less than or equal to 0.2, such as 0.05, 0.08, 0.1, 0.12, 0.15, 0.18, 0.2, etc., which are not listed here in this disclosure. By making the spacing xy between the end of the second cleaning head close to the first cleaning head 210 and the rotation axis of the swing arm 220 relatively small compared to the spacing x between the end of the second cleaning head close to the first cleaning head 210 and the axis of symmetry of the cleaning device 10 in the second direction, the area on the side of the end of the second cleaning head close to the first cleaning head 210 facing the periphery can be cleaned by the first cleaning head 210, thereby improving the cleaning effect. Of course, the ratio of the spacing xy between the end of the second cleaning head close to the first cleaning head 210 and the rotation axis of the swing arm 220 and the spacing x between the end of the second cleaning head close to the first cleaning head 210 and the axis of symmetry of the cleaning device 10 in the second direction can also be less than 0.05 or greater than 0.2, which is not limited in this disclosure.

[0053] Among them, the distance x between the end of the second cleaning head close to the first cleaning head 210 and the symmetry axis of the cleaning device 10 in the second direction can be 100mm~130mm, for example, 100mm, 105mm, 110mm, 115mm, 120mm, 125mm, 130mm, etc.

[0054] Among them, the distance between the rotation axis of the swing arm 220 and the symmetry axis of the cleaning device 10 in the second direction can be 120mm~140mm, for example, 120mm, 125mm, 130mm, 130.9mm, 135mm, 140mm, etc.

[0055] Among them, the rotation radius a of the side brush can be 60mm~80mm, such as 60mm, 62mm, 65mm, 68mm, 70mm, 72mm, 75mm, 78mm, 80mm, etc., which are not listed one by one in this disclosure.

[0056] Among them, the distance b between the rotating axis of the swing arm 220 and the rotating axis of the side brush can be 40mm~70mm, for example, 40mm, 42mm, 45mm, 48mm, 50mm, 52mm, 55mm, 55.56mm, 58mm, 60mm, 62mm, 65mm, 68mm, 70mm, etc., which are not listed one by one in this disclosure.

[0057] In one embodiment, as shown in FIG2 and FIG5 , the device body 100 is circular, and the diameter of the device body 100 is d. The spacing between the rotation axis of the swing arm 220 and the axis of symmetry of the cleaning device 10 in the forward direction Z is g, and the ratio of g to d is greater than or equal to 0.3 and less than or equal to 0.4, such as 0.3, 0.32, 0.35, 0.38, 0.4, etc., which are not listed here in this disclosure. By making the ratio of the spacing g between the rotation axis of the swing arm 220 and the axis of symmetry of the cleaning device 10 in the forward direction Z to the diameter d of the device body 100 greater than or equal to 0.3 and less than or equal to 0.4, that is, the rotation axis position of the swing arm 220 is relatively close to the front position of the device body 100, the length of the swing arm 220 can be relatively small, thereby improving the stability of the swing arm 220 and improving the cleaning effect of the side brush. At the same time, it also ensures that when the swing arm 220 is in the retracted position, the first cleaning area S1 of the side brush and the second cleaning area S2 of the roller brush have an overlapping portion. Of course, the ratio of the distance g between the rotation axis of the arm and the symmetry axis of the cleaning device 10 in the forward direction Z to the diameter d of the device body 100 may also be less than 0.3 or greater than 0.4, and this disclosure does not impose any limitation on this.

[0058] Among them, the distance between the rotation axis of the swing arm 220 and the symmetry axis of the cleaning device 10 in the forward direction Z can be 70mm to 80mm, for example, 70mm, 72mm, 73.25mm, 75mm, 78mm, 80mm, etc.

[0059] The diameter of the device body 100 may be 320 mm to 380 mm, for example, 320 mm, 330 mm, 340 mm, 350 mm, 360 mm, 370 mm, 380 mm, etc.

[0060] In one embodiment, as shown in FIG5 , the device body 100 is circular, and the diameter of the device body 100 is d; the spacing between the rotation axis of the swing arm 220 and the axis of symmetry of the cleaning device 10 in the second direction is y, and the ratio of y to d is greater than or equal to 0.1 and less than or equal to 0.3, such as 0.1, 0.15, 0.2, 0.25, 0.3, etc., which are not listed here in this disclosure. By making the ratio of the spacing y between the rotation axis of the swing arm 220 and the axis of symmetry of the cleaning device 10 in the second direction to the diameter d of the device body 100 greater than or equal to 0.1 and less than or equal to 0.3, the rotation axis of the swing arm 220 and the roller brush have an overlapping portion in the first direction, thereby improving the cleaning effect.

[0061] In one embodiment, as shown in Figure 5, in the forward direction Z, the distance between the rotating axis of the first cleaning head 210 and the axis of symmetry of the cleaning device 10 is h, and the distance between the end of the second cleaning head close to the first cleaning head 210 and the axis of symmetry of the cleaning device 10 is m, where h is greater than m.

[0062] When the side brush is in the recovery position and the extended position, the distance h between the rotating axis of the side brush and the axis of symmetry of the cleaning device 10 in the forward direction Z is greater than the distance m between the end of the second cleaning head close to the first cleaning head 210 and the axis of symmetry of the cleaning device 10 in the forward direction Z, so that the side brush is closer to the periphery of the device body 100 relative to the roller brush in the forward direction Z, and the first cleaning area S1 formed by the side brush can be closer to the periphery of the device body 100, thereby improving the cleaning effect; at the same time, the length and swing range of the swing arm 220 can be relatively small, thereby improving the stability of the swing arm 220, thereby improving the stability of the side brush and improving the cleaning effect.

[0063] In one embodiment, in a second direction perpendicular to the forward direction Z of the cleaning device 10, the distance between the rotating axis of the first cleaning head 210 and the axis of symmetry of the cleaning device 10 is k, and the distance between the side of the second cleaning head close to the first cleaning head 210 and the axis of symmetry of the cleaning device 10 is x, where k is greater than x.

[0064] When the side brush is in the retracted and extended positions, the spacing k between the side brush's rotation axis and the axis of symmetry of the cleaning device 10 in the second direction is greater than the spacing x between the side of the second cleaning head proximate to the first cleaning head 210 and the axis of symmetry of the cleaning device 10 in the second direction. When the side brush is in the retracted position, there is spacing between the side brush's rotation axis and the adjacent side of the roller brush in the second direction. This ensures that the first cleaning area S1 formed by the side brush overlaps with the second cleaning area S2 formed by the roller brush. This allows the side brush to be closer to the periphery of the device body 100 in the second direction, thereby improving the cleaning effect. At the same time, this allows the length and swing range of the swing arm 220 to be relatively small, thereby improving the stability of the swing arm 220, thereby improving the stability of the side brush and the cleaning effect.

[0065] In one embodiment, the sensing module includes a position determination device located on the housing of the device body 100, a collision sensor located on the bumper of the forward portion of the housing, a proximity sensor located on the housing, a cliff sensor located at the bottom of the housing, and sensing devices such as a magnetometer, accelerometer, gyroscope, and odometer located within the housing. These sensing devices are used to provide the control module with various position and motion status information of the cleaning device 10. The position determination device may be a camera or a laser rangefinder.

[0066] In one embodiment, the control module is provided on a circuit board inside the housing, and includes a non-transitory memory, such as a hard disk, a flash memory, a random access memory, and a communication computing processor, such as a central processing unit, an application processor. The application processor uses a positioning algorithm, such as real-time positioning and map construction, based on the obstacle information fed back by the laser ranging device to draw a real-time map of the environment in which the cleaning device 10 is located. In addition, the control module is combined with the distance information and speed information fed back by the sensors, cliff sensors, magnetometers, accelerometers, gyroscopes, odometers and other sensor devices provided on the buffer to comprehensively judge the current working state and position of the cleaning device 10, as well as the current posture of the cleaning device 10, such as passing the threshold, being on the carpet, being on the cliff, being stuck above or below, the suction tank is full, being picked up, etc., and a specific next action strategy is given for different situations, so that the cleaning device 10 has better cleaning performance and user experience.

[0067] In one embodiment, the cleaning device 10 further includes a mopping module and a liquid supply module. The mopping module includes a wet cleaning head, and the liquid supply module includes a liquid supply assembly that delivers cleaning liquid to the wet cleaning head. The wet cleaning head can be positioned below the liquid supply assembly, with the cleaning liquid within the liquid supply assembly being transferred to the wet cleaning head via a water supply mechanism, allowing the wet cleaning head to wet clean the surface to be cleaned. Of course, the cleaning liquid within the liquid supply assembly can also be sprayed directly onto the surface to be cleaned, with the wet cleaning head cleaning the surface by evenly applying the cleaning liquid.

[0068] As shown in Figure 2, the wet cleaning head can be arranged at the bottom of the cleaning device 10. The wet cleaning head can be, for example, a cleaning pad arranged parallel to the surface to be cleaned. The wet cleaning head is used to clean the surface to be cleaned, and the driving assembly is used to drive the wet cleaning head to basically reciprocate along the target surface, and the target surface is a part of the surface to be cleaned. The wet cleaning head reciprocates along the surface to be cleaned, and a cleaning cloth or a cleaning plate is provided on the contact surface between the wet cleaning head and the surface to be cleaned. The reciprocating motion generates high-frequency friction with the surface to be cleaned, thereby removing stains on the surface to be cleaned. The higher the friction frequency, the more friction times per unit time. The high-frequency reciprocating motion has a much greater cleaning ability than ordinary reciprocating motion, such as rotation and friction cleaning. Optionally, the friction frequency is close to that of sound waves, and the cleaning effect will be much higher than that of rotational friction cleaning of dozens of revolutions per minute. On the other hand, the hair tufts on the surface of the wet cleaning head will extend in the same direction more uniformly under the vibration of high-frequency vibration, so the overall cleaning effect is more uniform, instead of just applying downward pressure to increase friction and improve the cleaning effect under low-frequency rotation. The downward pressure alone will not make the hair tufts extend in nearly the same direction. The effect is that the water marks on the surface to be cleaned after high-frequency vibration cleaning are more uniform, and no messy water stains are left.

[0069] In one embodiment, the battery module includes rechargeable batteries, such as nickel-metal hydride batteries and lithium batteries. The rechargeable batteries can be connected to a charging control circuit, a battery pack charging temperature detection circuit, and a battery undervoltage monitoring circuit.
