[0041] This disclosure relates to a cleaning device. As shown in Figures 1 to 5, the cleaning device 10 comprises 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. The first cleaning head 210 is capable of forming a first cleaning zone S1 when the first cleaning head is operating. The second cleaning module 300 is disposed on the device body 100 and includes a second cleaning head. The second cleaning head is capable of forming a second cleaning zone S2 when the second cleaning head is operating.Depending on whether one is in the first or second operating situation, the first cleaning zone SI and the second cleaning zone S2 overlap at least partially or do not overlap when the first cleaning module 200 and the second cleaning module 300 operate simultaneously.

[0042] The cleaning device 10 provided by this disclosure comprises the first cleaning module 200 and the second cleaning module 300. The first cleaning zone S1 can be formed when the first cleaning head 210 rotates, the second cleaning zone S2 can be formed when the second cleaning head rotates, and the first cleaning zone S1 and the second cleaning zone S2 overlap at least partially or not at all, depending on whether one is in the first or second operating situation. In other words, the debris cleaned by one cleaning module 200 can be processed by the other cleaning module 300 in a centralized manner, thus improving the cleaning efficiency and the cleaning effect of the cleaning device 10.

[0043] In one embodiment, the first cleaning module 200 comprises a drive assembly, a pivoting arm 220, and a first cleaning head 210. A first end of the pivoting arm 220 is rotatably mounted on the device body 100, and the pivoting arm 220 can be positioned in a retracted position and a deployed position relative to the device body 100. by pivoting. A side brush is mounted on a second end of the pivoting arm 220. As described in figures 1 and 2, when the pivoting arm 220 is located in the retracted position, there is an overlapping part between the first cleaning zone SI formed by the first cleaning head 210 and the second cleaning zone S2.

[0044] As described in Figures 3 and 4, when the pivoting arm 220 is in the deployed position, there is no overlap between the first cleaning zone S1 and the second cleaning zone S2. When the pivoting arm 220 is in the deployed position, more cleaning zones are provided, thus improving the cleaning effect of the cleaning device 10.

[0045] The first cleaning head 210 can be a side brush, which forms the first cleaning zone S1 in a circular shape as it rotates. As shown in [Fig. 6], the side brush comprises a mounting portion 211 and a plurality of brush claws 212 connected to the mounting portion 211. The plurality of brush claws 212 are rotatably mounted on the pivoting arm 220 via the mounting portion 211. The plurality of brush claws 212 are of the same length, and the side brush comprises three brush claws 212 that are evenly distributed in a circumferential direction to enhance the cleaning effect of the side brush. Obviously, the side brush can also comprise two, four, or more than four brush claws 212.

[0046] The first end of the swivel arm 220 is connected to the drive assembly. The swivel arm 220 can be equipped with a gear set, such that an output shaft from the drive assembly drives the brush head to rotate at a high speed. The rotational speed of the brush head can vary from 500 rpm to 3,000 rpm to improve cleaning efficiency and effect. The rotational speed can be, for example, 500 rpm, 800 rpm, 1,000 rpm, 2,000 rpm, 3,000 rpm, etc., which are not listed individually in this disclosure. Of course, the rotational speed of the brush head can also be lower than 500 rpm or higher than 3,000 rpm, which is not limited by this disclosure.

[0047] A receiving space can be defined in the pivoting arm 220 for mounting the gear assembly in the pivoting arm 220. The pivoting arm 220 can have a cuboid-type structure overall, and an extension direction of the pivoting arm 220 can be a direction along the length of the pivoting arm 220. The pivoting arm 220 pivots in the width direction of the pivoting arm 220. The receiving space formed by the pivoting arm 110 in the thickness direction of the pivoting arm 220 is dimensioned to receive only the gear assembly, so as to prevent the pivoting arm 220 from being too large.

[0048] The pivoting arm 220 can pivot oscillatingly within a predefined angle range via the drive assembly, and the drive assembly that drives the pivoting arm 220 and the drive assembly that drives the brush head can be two independent drive assemblies. Alternatively, the pivoting arm 220 is rotationally connected to the drive assembly but is not driven by it; the pivoting arm 220 can pivot relative to the drive assembly under the effect of an external force to change the position of the brush head relative to a housing.

[0049] The pivoting arm 220 pivots back and forth within a predefined angle range, and the predefined angle can be from 20° to 120°, for example 20°, 30°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, etc., which are not listed one by one in this disclosure.

[0050] The pivoting arm 220 can pivot oscillatingly within a predefined angle range via the drive assembly, and the drive assembly that drives the pivoting arm 220 and the drive assembly that drives the brush head can be two independent drive assemblies. Alternatively, the pivoting arm 220 is rotationally connected to the drive assembly but is not driven by it, and the pivoting arm 220 can pivot relative to the drive assembly under the effect of an external force to change the position of the brush head relative to the device body 100.

[0051] In one embodiment, the second cleaning module 300 comprises a negative pressure fan, a dust suction box, a dust suction channel, and a roller brush. The outlet of the dust suction channel is connected to the dust suction box, and the inlet of the dust suction channel is exposed through a cover plate. The negative pressure fan is in communication with the dust suction box, such that the dust suction box is maintained in a negative pressure state when the cleaning device 10 performs a cleaning operation, and thus one inlet of the dust suction channel is in a negative pressure state.The dust extraction port is equipped with a roller brush that rotates around an axis parallel to the floor. The roller brush, which makes some contact with the floor, sweeps debris from the floor, rolling and transporting it into the dust extraction channel. The debris is then drawn into the dust extraction box by suction gas, which is generated by a negative pressure fan and passes through the dust extraction box. The cleaning area corresponding to the roller brush forms the second cleaning zone, S2.

[0052] A brush head of the first cleaning module 200 is arranged adjacent to the roller brush. The brush head rotates at high speed to sweep debris near the roller brush, then the debris is swept by the roller brush and carried by the bearing into the dust suction channel, drawn into the dust suction channel via the dust suction orifice under the effect of negative pressure, and enters the dust suction box, thus performing the debris cleaning operation on the surface to be cleaned.

[0053] As described in [Fig.2], the roller brush is located in a central position of a base of the cleaning device 10, and the brush head is located on a front side (front left or front right) of the roller brush, so that the debris swept by the brush head can be substantially located in the cleaning area corresponding to the roller brush, so as to better penetrate into the dust suction orifice.

[0054] The negative pressure supplied by the negative pressure fan can be from 3000 Pa to 7000 Pa to enhance the negative pressure suction effect on debris. The negative pressure can be, for example, 3000 Pa, 4000 Pa, 5000 Pa, 6000 Pa, 7000 Pa, etc., which are not listed individually in this disclosure. Obviously, the negative pressure supplied by the negative pressure fan can also be less than 3000 Pa or greater than 7000 Pa, which is not limited in this disclosure.

[0055] There may be two roller brushes, which rotate towards each other to sweep up debris and carry the debris by rolling into the dust suction channel.

[0056] In one embodiment, as described in [Fig. 2], the first cleaning zone S1 formed by the side brush is circular, and the second cleaning zone S2 formed by the roller brush is rectangular. Since the side brush is located on the front side relative to the roller brush in the Z direction of travel of the cleaning device 10, the overlap between the first cleaning zone S1 and the second cleaning zone S2 is located in a corner of the second cleaning zone S2 near the side brush. When the side brush sweeps debris towards the roller brush, the debris can be positioned substantially in front of the roller brush, which facilitates the roller brush sweeping the debris and rolling it into the dust suction channel, thus improving the cleaning effect.

[0057] In one embodiment, the drive module can manipulate the cleaning device 10 to move across the floor in a forward direction Z based on a drive command with distance and angle information. The drive module may include a first drive wheel module and a second drive wheel module. The first drive wheel module and the The second drive wheel module is arranged along a transverse axis defined by the cleaning device 10, and the extension direction of the transverse axis is simply the Z-direction of travel of the cleaning device 10. To enable the cleaning device 10 to move more stably or powerfully across the ground, the cleaning device 10 may include one or more drive wheels, including, but not limited to, universal wheels. The drive wheel module comprises a walking wheel, a drive motor, and a control circuit for operating the drive motor. The drive wheel module may also be connected to a circuit for measuring the drive current and an odometer. The drive wheel module can be removably connected to a lower housing for convenient disassembly / assembly and maintenance.The drive wheel can be equipped with a downwardly loaded suspension system, which is movably fixed, for example rotatably fixed, connected to the lower housing, and receives a downward and opposite spring load from the lower housing. The spring load allows the drive wheel to maintain contact and traction with the ground with a certain degree of ground adhesion, while the cleaning head of the cleaning device 10 is also maintained in contact with the ground with a certain pressure.

[0058] In one embodiment, as described in [Fig. 5], the distance between an end of the second cleaning head near the first cleaning head 210 and an axis of symmetry of the cleaning device 10 in a second direction is x, the distance between the rotation shaft of the pivoting arm 220 and the axis of symmetry of the cleaning device 10 in the second direction is y, and x > y. The Z-direction of advancement of the cleaning device 10 is a first direction, and the second direction is perpendicular to the first direction.The distance x between the end of the second cleaning head near the first cleaning head 210 and the axis of symmetry of the cleaning device 10 in the second direction is defined so as to be greater than the distance y between the rotation shaft of the pivoting arm 220 and the axis of symmetry of the cleaning device 10 in the second direction, i.e. the pivoting arm 220 and the roller brush have an overlapping part in the first direction, and the cleaning effect can thus be improved.

[0059] Specifically, (x - y): x = 0.05 to 0.2, for example, 0.05, 0.08, 0.1, 0.12, 0.15, 0.18, 0.2, etc., which are not listed one by one in this disclosure. The distance x - y between the end of the second cleaning head near the first cleaning head 210 and the rotation shaft of the pivoting arm 220 is defined so as to be relatively less than the distance x between the end of the second cleaning head near the first cleaning head 210 and the axis of symmetry of the device The cleaning head 10 is positioned in the second direction, such that an area on one side of the end of the second cleaning head, which is close to the first cleaning head 210 and faces outwards, can be cleaned by the first cleaning head 210, thus improving the cleaning effect. Obviously, the ratio of the distance x - y between the end of the second cleaning head near the first cleaning head 210 and the rotation shaft of the pivoting arm 220 to the distance x between the end of the second cleaning head near 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.

[0060] More specifically, the distance 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 be from 100 mm to 130 mm, for example 100 mm, 105 mm, 110 mm, 115 mm, 120 mm, 125 mm, 130 mm, etc.

[0061] More specifically, the distance between the rotation shaft of the pivoting arm 220 and the axis of symmetry of the cleaning device 10 in the second direction can be from 120 mm to 140 mm, for example 120 mm, 125 mm, 130 mm, 130.9 mm, 135 mm, 140 mm, etc.

[0062] More specifically, the radius of rotation of the side brush can be from 60 mm to 80 mm, for example 60 mm, 62 mm, 65 mm, 68 mm, 70 mm, 72 mm, 75 mm, 78 mm, 80 mm, etc., which are not listed one by one in this disclosure.

[0063] More specifically, the distance b between the rotating shaft of the pivoting arm 220 and the rotating shaft of the side brush can be from 40 mm to 70 mm, for example 40 mm, 42 mm, 45 mm, 48 mm, 50 mm, 52 mm, 55 mm, 55, 56 mm, 58 mm, 60 mm, 62 mm, 65 mm, 68 mm, 70 mm, etc., which are not listed one by one in this disclosure.

[0064] In one embodiment, as described in [Fig.2] and [Fig.5], the device body 100 is circular in shape, a diameter of the device body 100 is d, a distance between the rotation shaft of the pivoting arm 220 and the axis of symmetry of the cleaning device 10 in the advancement direction Z is g, and g: d = 0.3 to 0.4, such as 0.3, 0.32, 0.35, 0.38, 0.4, etc., which are not listed one by one in this disclosure.The ratio of the distance g between the rotation shaft of the pivoting 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 is defined to be 0.3 to 0.4, the position of the rotation shaft of the pivoting arm 220 is relatively close to a forward position of the device body 100, so that the length of the pivoting arm 220 can be relatively small, which improves the stability of the pivoting arm 220 and improves the cleaning effect of the side brush; moreover, it is also guaranteed that when the pivoting arm 220 is located in the retracted position, the first area of ​​. The side brush cleaning zone SI and the second roller brush cleaning zone S2 have an overlapping portion. Obviously, the ratio of the distance g between the arm's rotation shaft and the axis of symmetry of the cleaning device 10 in the Z-direction to the diameter d of the device body 100 can also be less than 0.3 or greater than 0.4, which is not limited in this disclosure.

[0065] More specifically, the distance between the rotation shaft of the pivoting arm 220 and the axis of symmetry of the cleaning device 10 in the Z-direction of advancement can be from 70 mm to 80 mm, for example, 70 mm, 72 mm, 73.25 mm, 75 mm, 78 mm, 80 mm, etc.

[0066] More specifically, the diameter of the device body 100 can be from 320 mm to 380 mm, for example 320 mm, 330 mm, 340 mm, 350 mm, 360 mm, 370 mm, 380 mm, etc.

[0067] In one embodiment, as described in [Fig.5], the device body 100 is circular in shape, the diameter of the device body 100 is d, the distance between the rotation shaft of the pivoting arm 220 and the axis of symmetry of the cleaning device 10 in the second direction is y, and y: d = 0.1 to 0.3, for example, 0.1, 0.15, 0.2, 0.25, 0.3, etc., which are not listed one by one in this disclosure. The ratio of the distance y between the rotation shaft of the pivoting 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 is defined to be from 0.1 to 0.3, such that the rotation shaft of the pivoting arm 220 and the roller brush have an overlapping part in the first direction, which improves the cleaning effect.

[0068] In one embodiment, as described in [Fig.5], in the Z-direction of advancement, a distance between the rotation shaft of the first cleaning head 210 and the axis of symmetry of the cleaning device 10 is h, a 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, and h > m.

[0069] When the side brush is in the retracted and extended positions, the distance h between the rotation shaft of the side brush and the axis of symmetry of the cleaning device 10 in the Z-direction is greater than the distance m between the end of the second cleaning head near the first cleaning head 210 and the axis of symmetry of the cleaning device 10 in the Z-direction. Therefore, the side brush is closer to the periphery of the device body 100 than the rotating brush in the Z-direction, and the first cleaning zone SI formed by the side brush can be closer to the periphery of the device body 100, thus improving the cleaning effect. Furthermore, the length and pivoting range of the pivoting arm 220 can be relatively small, which improves the stability of the 220 pivoting arm, which in turn improves the stability of the side brush and enhances the cleaning effect.

[0070] In one embodiment, in the second direction perpendicular to the Z-direction of advancement of the cleaning device 10, a distance between the rotation shaft of the first cleaning head 210 and the axis of symmetry of the cleaning device 10 is k, 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, and k > x.

[0071] When the side brush is located in the retracted position and in the deployed position, the distance k between the rotation shaft of the side brush and the symmetrical axis of the cleaning device 10 in the second direction is greater than the distance x 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 in the second direction.When the side brush is in the retracted position, there is a distance between the rotation shaft of the side brush and a side of the roller brush adjacent to the side brush in the second direction. In a case where there is an overlap between the first cleaning zone SI formed by the side brush and the second cleaning zone S2 formed by the roller brush, the side brush can be closer to the periphery of the device body 100 in the second direction, and in turn, the first cleaning zone SI formed by the side brush can be closer to the periphery of the device body 100, which improves the cleaning effect. Furthermore, the length and pivoting range of the pivoting arm 220 can be relatively small, which improves the stability of the pivoting arm 220, which, in turn, improves the stability of the side brush and enhances the cleaning effect.

[0072] In one embodiment, the detection module includes a position determination means located on the housing of the device body 100, a collision sensor disposed on a pad of a front component of the housing, a proximity sensor disposed on the housing, a scarpment sensor disposed in a lower part of the housing, and a detection means such as a magnetometer, an accelerometer, a gyroscope, an odometer disposed inside the housing, which are configured to provide the control module with various position information and information on the movement state of the cleaning device 10. The position determination means may be a camera or a laser rangefinder means.

[0073] In one embodiment, the control module is arranged on the printed circuit board in the housing, comprising a non-temporary memory, such as a hard drive, a flash memory, a random access memory, and a computer communication processor, such as a central processing unit, and an application processor. The application processor uses a positioning algorithm, such as real-time positioning and map construction, to draw a real-time map of the environment in which the cleaning device is located, based on obstacle information returned by the laser rangefinder. This is further combined with distance and speed information returned by sensing devices such as the pad sensor, the slope sensor, the magnetometer, the accelerometer, the gyroscope, the odometer, etc., it is determined exhaustively that the operating state or location of the cleaning device, and the current posture of the cleaning device 10, such as (the cleaning device) passing over a door threshold, located on a carpet, located at the level of a cliff, an upper or lower (part) being stuck, the dust suction box being full, (the cleaning device) being picked up, etc., and a specific next action strategy can be given for a different situation, so that the cleaning device 10 can provide better cleaning performance and a better user experience. .

[0074] In one embodiment, the cleaning device 10 further comprises a cleaning module and a liquid supply module. The washing 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 may be arranged below the liquid supply assembly, and the cleaning liquid inside the liquid supply assembly is conveyed to the wet cleaning head via a water supply mechanism, such that the wet cleaning head performs wet cleaning on the surface to be cleaned.Of course, the cleaning fluid inside the fluid supply assembly can also be sprayed directly onto the surface to be cleaned, and the wet cleaning head cleans the surface by evenly applying the cleaning fluid to the surface.

[0075] As described in [Fig. 1], the wet cleaning head can be disposed at the base 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 configured to clean the surface to be cleaned, and a drive assembly is configured to drive the wet cleaning head to perform essentially a back-and-forth motion along a target surface as part of the surface to be cleaned. The wet cleaning head performs a back-and-forth motion along the surface to be cleaned, and a cleaning cloth or cleaning plate is disposed on a contact surface of the wet cleaning head that comes into contact with the surface to be cleaned. High-frequency friction with the The surface to be cleaned is cleaned by a back-and-forth motion, which removes stains. The higher the friction frequency, the greater the number of frictions per unit of time. The cleaning capacity of a high-frequency back-and-forth motion is significantly superior to that of ordinary back-and-forth motions, such as rotary and scrubbing cleaning. Furthermore, when the friction frequency approaches the sound wave, the cleaning effect is considerably better than that of rotary scrubbing at tens of revolutions per minute.Furthermore, the tufts of bristles on the surface of the wet cleaning head spread more uniformly in the same direction under the effect of high-frequency vibrations, resulting in a more even overall cleaning effect. This is in contrast to simply applying downward pressure to increase friction and improve cleaning under low-frequency rotation. Downward pressure alone cannot cause the bristle tufts to spread in virtually the same direction. The effect of this disclosure is that after cleaning with high-frequency vibrations, the water marks on the surface being cleaned are more uniform, without leaving unsightly water spots.

[0076] In one embodiment, the battery module comprises a rechargeable battery, such as a nickel-metal hydride (Ni-MH) battery, and a lithium battery. The rechargeable battery can be connected to a charge control circuit, a battery pack charge temperature detection circuit, and a battery undervoltage monitoring circuit, and the charge control circuit, the battery pack charge temperature detection circuit, and the battery undervoltage monitoring circuit are in turn connected to a single-chip control circuit. The cleaning device can be charged by connecting a charging electrode disposed on the device body, for example, on the side, bottom, or top of the device body, to a charging cell.
