[0041] The present disclosure relates to a cleaning device. As described in FIGS. 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 comprises a first cleaning head 210, and the first cleaning head 210 is capable of forming a first cleaning area S1 when the first cleaning head is operating. The second cleaning module 300 is disposed on the device body 100 and comprises a second cleaning head, and the second cleaning head is capable of forming a second cleaning area S2 when the second cleaning head is operating.Depending on whether one is in the first or second operating situation, the first cleaning zone S1 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 the present disclosure comprises the first cleaning module 200 and the second cleaning module 300. The first cleaning area S1 may be formed when the first cleaning head 210 rotates, the second cleaning area S2 may be formed when the second cleaning head rotates, and the first cleaning area S1 and the second cleaning area S2 at least partially overlap or do not overlap, depending on whether it is the first or the second operating situation. That is, the debris cleaned by one cleaning module 200 may be processed by the other cleaning module 300 centrally, thereby improving the cleaning efficiency and cleaning effect of the cleaning device 10.

[0043] In one embodiment, the first cleaning module 200 includes a drive assembly, a pivoting arm 220, and a first cleaning head 210. A first end of the pivoting arm 220 is rotatably mounted to the device body 100, and the pivoting arm 220 is positionable in a retracted position and an extended 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 portion between the first cleaning area S1 formed by the first cleaning head 210 and the second cleaning area S2.

[0044] As described in Figures 3 and 4, when the pivot arm 220 is located in the extended position, there is no overlapping portion between the first cleaning area S1 and the second cleaning area S2. When the pivot arm 220 is located in the extended position, more cleaning areas are provided, thereby improving the cleaning effect of the cleaning device 10.

[0045] The first cleaning head 210 may be a side brush, which forms the first cleaning area S1 in a circular shape by rotating. As described in [Fig. 6], the side brush comprises a mounting portion 211 and a plurality of brush claws 212 connected to the mounting portion 211, and the plurality of brush claws 212 are rotatably mounted on the pivot arm 220 via the mounting portion 211. The plurality of brush claws 212 have the same length, and the side brush comprises three brush claws 212 which are uniformly distributed in a circumferential direction of the side brush to improve the cleaning effect of the side brush. Obviously, the side brush may also comprise two, four or more brush claws 212.

[0046] The first end of the pivot arm 220 is connected to the drive assembly. The pivot arm 220 may be equipped with a gear assembly, such that an output shaft of the drive assembly drives the brush head to rotate at a high speed. The rotational speed of the brush head may vary from 500 rpm to 3000 rpm, to improve the cleaning efficiency and cleaning effect. The rotational speed may be, for example, 500 rpm, 800 rpm, 1000 rpm, 2000 rpm, 3000 rpm, etc., which are not listed one by one in the present disclosure. Of course, the rotational speed of the brush head may also be lower than 500 rpm or higher than 3000 rpm, which is not limited in the present disclosure.

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

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

[0049] The pivot arm 220 pivots back and forth within a predefined angle range, and the predefined angle may be 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 the present disclosure.

[0050] The pivot arm 220 can swingably pivot within a predefined angle range via the drive assembly, and the drive assembly that drives the pivot arm 220 and the drive assembly that drives the brush head can be two independent drive assemblies. Alternatively, the pivot arm 220 is rotatably connected to the drive assembly and is not driven by the drive assembly, and the pivot arm 220 can pivot relative to the drive assembly under an external force to change a 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 from 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 an inlet of the dust suction channel is in a negative pressure state.The dust suction port is provided with a roller brush which rotates around an axis parallel to the ground, the roller brush, which has a certain interference with the ground, sweeps the debris on the ground, rolls and transports the debris into the dust suction channel, and the debris is sucked into the dust suction box by the suction gas, the suction gas being generated by the negative pressure fan and passing through the dust suction box. The cleaning area corresponding to the roller brush forms the second cleaning area S2. .

[0052] A brush head of the first cleaning module 200 is disposed adjacent to the roller brush. The brush head rotates at a high speed to sweep debris near the roller brush, and then the debris is swept by the roller brush and is driven by the rolling into the dust suction channel, sucked into the dust suction channel via the dust suction port under the effect of the negative pressure, and enters the dust suction box, thereby completing the operation of cleaning the debris 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 (left front or right front) of the roller brush, so that debris swept by the brush head can be substantially located in the cleaning area corresponding to the roller brush, so as to better enter the dust suction port.

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

[0055] There may be two roller brushes, which rotate toward each other to sweep debris and roll the debris into the dust suction channel.

[0056] In one embodiment, as depicted in [Fig. 2], the first cleaning area S1 formed by the side brush is circular in shape, and the second cleaning area S2 formed by the roller brush is rectangular in shape. Since the side brush is located on a front side relative to the roller brush in the advancing direction Z of the cleaning device 10, the overlapping portion between the first cleaning area S1 and the second cleaning area S2 is located in a corner of the second cleaning area S2 near the side brush. When the side brush sweeps debris toward the roller brush, the debris can be substantially located in front of the roller brush, which is convenient for the roller brush to sweep the debris and roll it into the dust suction channel, thereby improving the cleaning effect.

[0057] In one embodiment, the drive module may 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 second drive wheel module are arranged along a transverse axis defined by the cleaning device 10, and an extension direction of the transverse axis is simply the advancing direction Z of the cleaning device 10. In order for the cleaning device 10 to move more stably or more powerfully on the ground, the cleaning device 10 may comprise one or more drive wheels, and the drive wheels include, but are not limited to, universal wheels. The drive wheel module comprises a walking wheel, a drive motor and a control circuit for controlling the drive motor, and the drive wheel module may also be connected to a circuit for measuring the drive current and an odometer. The drive wheel module may be detachably connected to a lower housing for convenient disassembly / assembly and maintenance.The drive wheel may be provided with a downwardly biased suspension system, which is movably attached, for example rotatably attached, connected to the lower housing, and receives a spring bias downward and away from the lower housing. The spring bias enables the drive wheel to maintain contact and traction with the ground with a certain degree of ground grip force, 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], a distance between an end of the second cleaning head close to the first cleaning head 210 and an axis of symmetry of the cleaning device 10 in a second direction is x, a 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 advancing direction Z 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 close to the first cleaning head 210 and the axis of symmetry of the cleaning device 10 in the second direction is set to be greater than the distance y between the rotation shaft of the pivot arm 220 and the axis of symmetry of the cleaning device 10 in the second direction, that is, the pivot arm 220 and the roller brush have an overlapping portion in the first direction, and thus the cleaning effect can 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 the present disclosure. The distance x - y between the end of the second cleaning head close to the first cleaning head 210 and the rotation shaft of the pivot arm 220 is set to be relatively smaller than 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 device cleaning head 10 in the second direction, so 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 outward, can be cleaned by the first cleaning head 210, thereby improving the cleaning effect. Obviously, a ratio of the distance x - y between the end of the second cleaning head close to the first cleaning head 210 and the rotation shaft of the pivot arm 220 to 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 may also be less than 0.05 or greater than 0.2, which is not limited in the present 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 may 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 may be 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 rotation radius a of the side brush may be 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 the present disclosure.

[0063] More specifically, the distance b between the rotation shaft of the pivot arm 220 and the rotation shaft of the side brush may be 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 the present 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 pivot arm 220 and the axis of symmetry of the cleaning device 10 in the advancing 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 the present disclosure.The ratio of the distance g between the rotation shaft of the swing arm 220 and the axis of symmetry of the cleaning device 10 in the advancing direction Z to the diameter d of the device body 100 is set to be 0.3 to 0.4, the position of the rotation shaft of the swing arm 220 is relatively close to a front position of the device body 100, so that 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; moreover, it is also ensured that when the swing arm 220 is located in the retracted position, the first area of . cleaning area SI of the side brush and the second cleaning area S2 of the roller brush have the overlapping portion. Obviously, the ratio of the distance g between the rotation shaft of the arm and the axis of symmetry of the cleaning device 10 in the advancing direction Z to the diameter d of the device body 100 may also be less than 0.3 or greater than 0.4, which is not limited in the present 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 advancing direction Z may be 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 may 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 pivot 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 the present disclosure. The ratio of the distance y between the rotation shaft 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 is set to be 0.1 to 0.3, so that the rotation shaft of the swing arm 220 and the roller brush have an overlapping portion in the first direction, thereby improving the cleaning effect.

[0068] In one embodiment, as described in [Fig.5], in the advancing direction Z, 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 located in the retracted position and the extended position, the distance h between the rotation shaft of the side brush and the axis of symmetry of the cleaning device 10 in the advancing 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 advancing direction Z, so that the side brush is closer to the periphery of the device body 100 than the rotating brush in the advancing 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; in addition, the length and the pivoting range of the pivot arm 220 can be relatively small, which helps improve the stability of the 220 swivel arm, which in turn improves the stability of the side brush and improves the cleaning effect.

[0070] In one embodiment, in the second direction perpendicular to the advancing direction Z 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 extended 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 symmetry axis of the cleaning device 10 in the second direction.When the side brush is located 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 the overlapping portion between the first cleaning area S1 formed by the side brush and the second cleaning area 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 area S1 formed by the side brush can be closer to the periphery of the device body 100, thereby improving the cleaning effect; in addition, the length and the swing range of the swing arm 220 can be relatively small, thereby improving the stability of the swing arm 220, which, in turn, improves the stability of the side brush and improves the cleaning effect.

[0072] In one embodiment, the detection module comprises a position determining 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 cliff sensor disposed in a lower portion 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 determining means may be a camera or a laser ranging means.

[0073] In one embodiment, the control module is disposed on the printed circuit board in the housing, comprising non-temporary memory, such as a hard disk, flash memory, random access memory, and a communication computer 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 the obstacle information returned by the laser ranging means. In addition, in combination with the distance information and the speed information returned by the detection means such as the sensor provided on the pad, the escarpment sensor, the magnetometer, the accelerometer, the gyroscope, the odometer, etc., it is determined, comprehensively, 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 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 comprises a wet cleaning head, and the liquid supply module comprises a liquid supply assembly that supplies a 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 transmitted 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 liquid inside the liquid 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 liquid to the surface.

[0075] As depicted in [Fig.l], the wet cleaning head may be disposed at the base of the cleaning device 10. The wet cleaning head may be, for example, a cleaning pad disposed 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 basically reciprocate along a target surface as a part of the surface to be cleaned. The wet cleaning head reciprocates 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 contacts the surface to be cleaned. High-frequency friction with the The cleaning surface is generated by the reciprocating motion, so that the stains on the surface to be cleaned are removed. The higher the rubbing frequency, the greater the number of rubbings per unit time. The cleaning ability of high-frequency reciprocating motion is significantly superior to that of ordinary reciprocating motion, such as rotary and rubbing cleaning. Optionally, in the case where the rubbing frequency is close to the sound wave, the cleaning effect is significantly better than that of rotary rubbing cleaning at tens of revolutions per minute.On the other hand, the tufts of bristles on a surface of the wet cleaning head extend in the same direction more uniformly under the effect of the high-frequency vibration, and thus the overall cleaning effect is more uniform, compared with simply applying downward pressure to increase friction to improve the cleaning effect under the low-frequency rotation. The downward pressure alone cannot make the tufts of bristles extend in almost the same direction. The effect of the present disclosure is that after the high-frequency vibration cleaning, the water marks on the surface to be cleaned are more uniform without leaving messy water stains.
