Embodiments of the present application

[0029] In order to make the person skilled in the art to which the present disclosure belongs more clearly understand the present disclosure, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present disclosure.

[0030] In the related art, the edge brush of the cleaning device such as a sweeping robot is always in a rotating state when working. When the cleaning device climbs over an obstacle or a carpet, the edge brush will hinder the robot from climbing or roll up the carpet, resulting in abnormal operation of the device and affecting user experience. In some embodiments, when the cleaning device such as a sweeping robot cleans corners and other cleaning conditions, the angle of the cleaning assembly on the main machine cannot be adjusted, which limits the cleaning effect and has room for improvement.

[0031] Based on the above technical problems, the present disclosure provides a cleaning module, a cleaning device and a cleaning system, so that the cleaning assembly can be suitable for various cleaning conditions.

The cleaning assembly 200 can swing to the first side 1021 and the second side 1022 in the swing opening 102. The first side 1021 and the second side 1022 are oppositely arranged and used to limit the swing position of the cleaning assembly 200. When the cleaning assembly 200 swings to the first side 1021, the cleaning assembly 200 is in a cleaning position to perform cleaning work. When the cleaning assembly 200 swings to the second side 1022, the cleaning assembly 200 is in a retracted position to clean corners and other cleaning working conditions and to avoid obstacles to a certain extent, so that the cleaning equipment can operate normally.

[0039] Referring to FIG. 6, the swing opening 102 further comprises a limiting portion 1023 arranged along the horizontal direction, one end of the limiting portion 1023 is connected with the first side portion 1021, and the other end of the limiting portion 1023 is spaced apart from the second side portion 1022, and the second side portion 1022 is higher than the first side portion 1021. In the condition that the cleaning assembly 200 is in the cleaning position, the cleaning assembly 200 abuts against the inner side of the first side portion 1021, when the cleaning assembly 200 is switched from the cleaning position to the retracted position, the cleaning assembly 200 moves along the limiting portion 1023 to the direction of the second side portion 1022 until the cleaning assembly 200 abuts against the inner side of the second side portion 1022. When the cleaning assembly 200 is controlled to be lifted up, the cleaning assembly 200 is lifted up along the second side portion 1022, so that the cleaning assembly 200 is switched from the retracted position to the lifted-up posture, to avoid the obstacle, so that the cleaning device can normally operate.

[0040] Referring to FIG. 6, the bottom of the first side portion 1021 and the bottom of the second side portion 1022 of the swing opening 102 can be located at the same horizontal plane, the top of the second side portion 1022 is higher than the top of the first side portion 1021, the distance between the limiting portion 1023 and the second side portion 1022 is slightly greater than the horizontal dimension of the brush housing 203 of the cleaning assembly 200, so that the cleaning assembly 200 can be lifted up and down between the limiting portion 1023 and the second side portion 1022.

[0041] FIG. 7 shows a structural schematic view of the power assembly in FIGS. 1-4, and FIG. 8 shows a structural schematic view of the base from another perspective in FIG. 6. Referring to FIGS. 6-8, the power assembly 300 comprises a power member 303, a first gear 304 and a second gear 305, the power member 303 can be a motor, a second assembly opening 105 is arranged on the base 100, the power member 303 is installed in the second assembly opening 105, the second assembly opening 105 can be arranged side by side with the first assembly opening 104, so that the power member 303 and the brush motor 206 are arranged side by side, to utilize the horizontal dimension of the base 100, to reduce the thickness of the base 100, the first gear 304 is connected to the output shaft of the power member 303, the second gear 305 is rotatably connected to the base 100 and is engaged with the first gear 304, a driving member is connected to the second gear 305, and the driving member is configured as the driving portion 301 of the power assembly 300. The first gear 304 can be sleeved on the output shaft of the power member 303, and the second gear 305 can be sleeved on the support sleeve 103, so that the second gear 305 can rotate around the support sleeve 103, and the radius of the second gear 305 is preferably greater than the radius of the first gear 304, to slow down the rotation speed of the second gear 305, and in turn to reduce the action amplitude of the cleaning assembly 200, and to improve the reliability of the movement of the cleaning assembly 200. A driving block is arranged on the top of the second gear 305, and the driving block can be configured as the driving portion 301 of the power assembly 300.

[0042] Fig. 9 shows a schematic diagram of the arrangement of the second gear in the base. Referring to Fig. 9, in an embodiment, the cleaning assembly 200 can further comprise a limiting member 400 arranged on the rotation path of the second gear 305 to limit the rotation angle of the second gear 305 and the driving part 301 of the power assembly 300. When the second gear 305 rotates, the second gear 305 is blocked by the limiting member 400, and the rotation of the second gear 305 and the driving part 301 of the power assembly 300 is stopped. In a specific implementation, a notch can be arranged on the circumferential surface of the second gear 305, the limiting member 400 is fixed on the bottom of the accommodating cavity 101 of the base 100, the limiting member 400 is located in the notch, and the limiting member 400 and the two sides of the notch have a distance to allow the second gear 305 to rotate by a set angle. In another embodiment, the limiting member 400 can also be arranged on the rotation path of the second gear 305. Alternatively, the limiting member 400 can be arranged on the rotation path of both the first gear 304 and the second gear 305. Alternatively, the circumferential surface of the first gear 304 or / and the second gear 305 can also not be provided with a notch, for example, the limiting member 400 is arranged outside the circumferential surface of the first gear 304 or / and the second gear 305, and a stopper is arranged on the circumferential surface of the circumferential surface of the first gear 304 or / and the second gear 305, which can be blocked by the limiting member 400 to block the rotation of the first gear 304 or / and the second gear 305. This way will occupy a larger space, which is an alternative solution.

[0043] Fig. 10 shows a schematic diagram of the assembly of the bristle brush housing and the base. Referring to Fig. 10, the cleaning module can further comprise a position sensor 500 to confirm the height position of the cleaning assembly 200. In a specific implementation, the position sensor 500 can be arranged on the outside of the base 100 and above the swing opening 102, when the cleaning assembly 200 is in the raised posture, the position sensor 500 confirms that the cleaning assembly 200 is raised to the position, and sends a signal to the controller that the cleaning assembly 200 is in place. The controller responds to the in-place signal of the cleaning assembly 200 to send an instruction to stop the rotation of the power part 303 of the power assembly 300, and controls the power part 303 of the power assembly 300 to stop rotating to keep the cleaning assembly 200 in the raised posture.

[0044] According to the cleaning module provided by the present disclosure, the rotation of the power part 303 of the power assembly 300 can be controlled by arranging the limiting member 400, and the rotation of the power part 303 of the power assembly 300 can also be controlled by the position sensor 500. In an embodiment, the limiting member 400 and the position sensor 500 can be included at the same time to realize the hardware and software control at the same time. In another embodiment, only one of the above-mentioned implementation ways can be included, which is not limited herein.

[0045] Referring to FIG. 10, the cleaning assembly 200 can further include a reset member 600 disposed between the cleaning assembly 200 and the base 100. When the cleaning assembly 200 is switched from the cleaning position to the retracted position, the reset member 600 is compressed and deformed. When the cleaning assembly 200 needs to be switched from the retracted position to the cleaning position, the power member 303 of the power assembly 300 is reversely rotated to drive the driven part 201 of the power assembly 300 to reversely rotate. At the same time, the reset member 600 restores the deformation to drive the cleaning assembly 200 to reversely rotate synchronously with the driven part 201 of the power assembly 300 until the side part of the cleaning assembly 200 abuts against the first side part 1021 of the swing opening 102. At this time, the cleaning assembly 200 is in the cleaning position, and the guide protrusion on the driving part 301 of the power assembly 300 is positioned on the top of the first recess 2021.

[0046] FIG. 11 shows a structural schematic view of the reset member in FIG. 10. Referring to FIGS. 10 and 11, the reset member 600 can be disposed between the top of the cleaning assembly 200 and the base 100, and the reset member 600 can be sleeved on the brush motor 206 of the cleaning assembly 200. The reset member 600 has two connecting ends, i.e., a first connecting end 601 and a second connecting end 602, which are respectively connected to the base 100 and the cleaning assembly 200.

[0047] Referring to FIGS. 10 and 11, in an embodiment, a first limiting groove 106 can be arranged on the peripheral surface of the base 100, and the first limiting groove 106 is in communication with the top of the swing opening 102, i.e., the opening of the first limiting groove 106 faces downward, and the first connecting end 601 of the reset member 600 is arranged in the first limiting groove 106. A connecting block 208 is arranged on the brush housing 203 of the cleaning assembly 200, and a second limiting groove 209 with an opening facing the horizontal direction is formed between the connecting block 208 and the brush body, and the second connecting end 602 of the reset member 600 is arranged in the second limiting groove 209 to realize the assembly of the reset member 600 on the cleaning assembly 200. In another embodiment, the two connecting ends of the reset member 600 can be respectively welded on the side wall of the base 100 and the top of the brush housing 203 of the cleaning assembly 200, which is not limited herein.

[0048] Fig. 12 shows a schematic diagram of the third gear driving part, Fig. 13 shows a schematic diagram of the cooperation between the driving part and the driven part when the cleaning assembly is in the cleaning position, Fig. 14 shows a schematic diagram of the cooperation between the driving part and the driven part when the cleaning assembly is in the retracted position, and Fig. 15 shows a schematic diagram of the cooperation between the driving part and the driven part when the cleaning assembly is in the obstacle avoidance position. Referring to Figs. 12-15, the first guide part 202 is a guide recess, and the second guide part 302 is a guide protrusion which can slide in the guide recess. In some embodiments, the guide recess 202 comprises a helical first recess 2021. As shown in Fig. 13, when the cleaning assembly 200 is in the cleaning position, the side of the cleaning assembly 200 abuts against the first side 1021 of the swing opening 102, and the top of the cleaning assembly 200 abuts against the first limiting side of the swing opening 102. The guide protrusion on the driving part 301 of the power assembly 300 is positioned on the top of the first recess 2021. The power member 303 of the power assembly 300 is controlled to rotate, so as to drive the driven part 201 of the power assembly 300 to rotate. The guide protrusion on the driven part 201 moves in the helical first recess 2021, so as to drive the cleaning assembly 200 to move along the first limiting part 1023 towards the second side 1022, until the other side of the cleaning assembly 200 abuts against the second side 1022. That is, as shown in Fig. 14, the cleaning assembly 200 is switched from the cleaning position to the retracted position, and the guide protrusion on the driving part 301 of the power assembly 300 remains positioned on the top of the first recess 2021.

[0049] Referring to Figs. 13-15, in some embodiments, the guide recess 202 further comprises a second recess 2022 which is arranged at the top end of the first recess 2021 and extends in the horizontal direction away from the first recess 2021. When the cleaning device is in operation, if the side of the cleaning assembly 200 encounters an obstacle, the obstacle will drive the cleaning assembly 200 to rotate inwards to retract. The above-mentioned reset member 600 will be compressed to buffer the cleaning assembly 200, so as to improve the service life of the cleaning assembly 200. When the obstacle on the side of the cleaning assembly 200 is removed, the reset member 600 restores the deformation, so as to drive the cleaning assembly 200 to move towards the cleaning position. The guide protrusion on the driving part 301 of the power assembly 300 moves in the second recess 2022 to adapt to the movement of the cleaning assembly 200.

[0050] Referring to FIGS. 14-15, when the cleaning assembly 200 is in the retracted position, if an obstacle needs to be avoided in the advancing direction of the cleaning device, the cleaning assembly 200 needs to be raised from the retracted position to an elevated position, i.e., to an obstacle-avoiding position. In a specific implementation, the power member 303 of the power assembly 300 is controlled to rotate, driving the guide protrusion on the driving portion 301 of the power assembly 300 to rotate in the first recess 2021. Since the cleaning assembly 200 is abutted against the second side portion 1022, the cleaning assembly 200 is driven to move upward along the second side portion 1022 under the action of the guide protrusion on the driving portion 301 of the power assembly 300, so that the cleaning assembly 200 is raised from the retracted position to the elevated position (obstacle-avoiding position) to avoid the obstacle. That is, as shown in FIG. 15, the cleaning device can be normally operated, and the user experience is improved. At this time, the guide protrusion on the driving portion 301 of the power assembly 300 is located at the bottom of the first recess 2021. When the cleaning assembly 200 is switched from the elevated position to the retracted position, the power member 303 of the power assembly 300 is controlled to reversely rotate, the driving portion 301 of the power assembly 300 is reversely rotated, the guide protrusion on the driving portion 301 of the power assembly 300 is moved from the bottom of the first recess 2021 to the top of the first recess 2021, and the cleaning assembly 200 is moved along the second side portion 1022 to the retracted position.

[0051] Under the condition that the cleaning assembly 200 is in the retracted position and the elevated position, the reset member 600 is in a compressed state. In order to prevent the cleaning assembly 200 from being kept in the elevated position (obstacle-avoiding position) under the action of the self-weight or / and the axial force exerted by the reset member 600, the guide recess 202 of the present disclosure further comprises a third recess 2023, which is arranged in a horizontal direction and extends away from the first recess 2021. When the cleaning assembly 200 is in the elevated position, the power member 303 of the power assembly 300 is continuously controlled to rotate, and the guide protrusion on the driving portion 301 of the power assembly 300 is moved from the bottom of the first recess 2021 to the third recess 2023. At this time, the cleaning assembly 200 is kept stationary. Through the limitation of the third recess 2023, the cleaning assembly 200 can be kept in the elevated position (obstacle-avoiding position), and accidental situations can be avoided.

[0052] It should be noted that in another embodiment, the first guide portion 202 is a guide protrusion, and the second guide portion 302 is a guide recess 302, i.e., the guide protrusion and the guide recess are reversely arranged, and the switching of the cleaning assembly in different positions can also be realized. For details, reference can be made to the foregoing description, which will not be repeated here.

[0053] Referring to FIGS. 14-15, in the above embodiment, the first guide portion 202 of the driving portion 301 is arranged at the outer circumferential side of the driven portion 201, i.e., the driving portion 301 of the power assembly 300 is arranged at the outer circumferential side of the driven portion 201. In another embodiment, the first guide portion 202 of the driving portion 301 can also be arranged at the inner circumferential side of the driven portion 201, i.e., the driven portion 201 is arranged at the outer circumferential side of the driving portion, and the switching of the cleaning assembly 200 between the cleaning position, the retracted position and the obstacle avoidance position can also be achieved.

[0054] In summary, according to the cleaning module provided by the present disclosure, the cleaning assembly 200 can switch between the cleaning position, the retracted position and the obstacle avoidance position to adapt to different cleaning working conditions, which has good practicability.
