[0054] In an embodiment, the base 100 of the present application can be connected by two single structures 107 to facilitate the assembly of internal parts. In another embodiment, the base 100 can also be a whole structure integrally formed,​​​Figure 6 The swing opening 102 is provided with a first side 1021 and a second side 1022, and 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 are 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 sweeping 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 perform corner cleaning and other cleaning work, and to a certain extent, avoid obstacles, so that the cleaning equipment can normally operate.

[0055] In combination with Figure 6 The swing opening 102 is further provided with a limiting portion 1023, the limiting portion 1023 is arranged in a horizontal direction, one end of the limiting portion 1023 is connected with the first side 1021, and the other end of the limiting portion 1023 is away from the second side 1022, and the second side 1022 is higher than the first side 1021. Under the condition that the cleaning assembly 200 is in the sweeping position, the cleaning assembly 200 abuts against the inner side of the first side 1021; when the cleaning assembly 200 is switched from the sweeping position to the retracted position, the cleaning assembly 200 moves along the limiting portion 1023 to the direction of the second side 1022, until the cleaning assembly 200 abuts against the inner side of the second side 1022; when the cleaning assembly 200 is controlled to rise, the cleaning assembly 200 rises along the second side 1022, so that the cleaning assembly 200 is switched from the retracted position to a rising posture, to avoid obstacles, so that the cleaning equipment can normally operate.

[0056] In combination with Figure 6 The bottom of the first side 1021 and the bottom of the second side 1022 of the swing opening 102 can be located in the same horizontal plane, the top of the second side 1022 is higher than the top of the first side 1021, the distance between the limiting portion 1023 and the second side 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 rise and fall between the limiting portion 1023 and the second side 1022.

[0057] Figure 7 The structure diagram of the power assembly in Figures 1-4 is shown, Figure 8 The structure diagram of another view of Figure 6 is shown. In combination with Figures 6-8The power assembly 300 comprises a power member 303, a first gear 304 and a second gear 305. The power member 303 can be an electric motor. The base 100 is provided with a second assembly opening 105. The power member 303 is assembled in the second assembly opening 105. The second assembly opening 105 can be arranged in parallel with the first assembly opening 104, so that the power member 303 is arranged in parallel with the bristle motor 206. The horizontal dimension of the base 100 is utilized 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 engaged with the first gear 304. A driving member is connected to the second gear 305. 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. 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. The radius of the second gear 305 is preferably greater than the radius of the first gear 304, so as to slow down the rotation speed of the second gear 305, thereby reducing the action amplitude of the cleaning assembly 200 and improving the reliability of the movement of the cleaning assembly 200. A driving block is arranged on the top of the second gear 305. The driving block can be configured as the driving portion 301 of the power assembly 300.

[0058] Figure 9 The arrangement of the second gear in the base is shown. In combination with the above description of the arrangement of the first gear in the base, Figure 9 In an embodiment, the cleaning assembly 200 further comprises a limiting member 400 arranged on the rotation path of the second gear 305, so as to limit the rotation angle of the second gear 305 and the driving portion 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 portion 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. The limiting member 400 and the two sides of the notch have a distance, so that the second gear 305 can 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 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. A blocking block is arranged on the circumferential surface of the circumferential surface of the first gear 304 or / and the second gear 305. The blocking block can be blocked by the limiting member 400, so as to block the rotation of the first gear 304 or / and the second gear 305. This way occupies a larger space and is an alternative solution.

[0059] Figure 10 The assembly of the bristle brush shell and the base is shown. In combination Figure 10 The cleaning module can also include a position sensor 500 to confirm the height position of the cleaning assembly 200. In 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 position, the position sensor 500 confirms that the cleaning assembly 200 has been raised to the correct position and sends a cleaning assembly 200 in position signal to the controller. The controller responds to the cleaning assembly 200 in position signal and sends an instruction to stop the power piece 303 of the power assembly 300 from rotating, thereby controlling the power piece 303 of the power assembly 300 to stop rotating and keeping the cleaning assembly 200 in the raised position.

[0060] The cleaning module provided in the present application can control the rotation of the power piece 303 of the power assembly 300 by arranging the limiting piece 400 or by the position sensor 500. In an embodiment, both the limiting piece 400 and the position sensor 500 can be included to achieve simultaneous hardware and software control. In another embodiment, only one of the above-mentioned implementation methods can be included, which is not limited herein.

[0061] In combination Figure 10 The cleaning assembly 200 can also include a reset piece 600 arranged between the cleaning assembly 200 and the base 100. When the cleaning assembly 200 switches from the cleaning position to the retracted position, the reset piece 600 is compressed and deformed. When the cleaning assembly 200 needs to switch from the retracted position to the cleaning position, the power piece 303 of the power assembly 300 is controlled to rotate in the opposite direction to drive the driven part 201 of the power assembly 300 to rotate in the opposite direction, and at the same time, the reset piece 600 recovers from deformation to drive the cleaning assembly 200 to rotate in the opposite direction 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 which 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.

[0062] Figure 11 The structure of the reset piece in Figure 10 is shown. In combination Figure 10 and Figure 11 The reset piece 600 can be arranged between the top of the cleaning assembly 200 and the base 100, and the reset piece 600 can be sleeved on the bristle brush motor 206 of the cleaning assembly 200. The reset piece 600 has two connecting ends, i.e., a first connecting end 601 and a second connecting end 602, which are connected to the base 100 and the cleaning assembly 200, respectively.

[0063] In combination Figure 10 And Figure 11 In an embodiment, a first limiting groove 106 can be arranged on the peripheral surface of the base 100, the first limiting groove 106 and the top of the swing opening 102 are communicated, that is, 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 side brush shell 203 of the cleaning assembly 200, and the connecting block 208 and the side brush body form a second limiting groove 209 with an opening facing the horizontal direction, and the second connecting end 602 of the reset member 600 is arranged in the second limiting groove 209, so as 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 side brush shell 203 of the cleaning assembly 200, which is not limited here.

[0064] Figure 12 A schematic view of the arrangement of the third gear and the driving part is shown, Figure 13 A schematic view of the cooperation of the driving part and the driven part when the cleaning assembly is in the cleaning position is shown, Figure 14 A schematic view of the cooperation of the driving part and the driven part when the cleaning assembly is in the retracted position is shown, Figure 15 A schematic view of the cooperation of the driving part and the driven part when the cleaning assembly is in the obstacle avoidance position is shown. In combination Figures 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, wherein the guide recess 202 includes a helical first recess 2021. As Figure 13 shown, 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, and the guide protrusion on the driving part 301 of the power assembly 300 is arranged at 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, and 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 in the direction of the second side 1022, until the other side of the cleaning assembly 200 abuts against the second side 1022, that is, as Figure 14 shown, 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 arranged at the top of the first recess 2021.

[0065] In combination Figures 13-15In addition, the guide recess 202 further comprises a second recess 2022 arranged at the top end of the first recess 2021 and extending 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 turn inwards to fold, and the reset member 600 will be compressed to buffer the cleaning assembly 200 and 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 recovers from deformation and drives the cleaning assembly 200 to move in the direction of the cleaning position, and 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.

[0066] In combination Figures 14-15 When the cleaning assembly 200 is in the folded position, if an obstacle in the forward direction of the cleaning device needs to be avoided, the cleaning assembly 200 needs to be raised from the folded position to an elevated posture, i.e., an obstacle avoidance position. In specific implementation, the power member 303 of the power assembly 300 is controlled to rotate, and the guide protrusion on the driving part 301 of the power assembly 300 is rotated in the first recess 2021. Since the cleaning assembly 200 abuts against the second side 1022, under the action of the guide protrusion on the driving part 301 of the power assembly 300, the cleaning assembly 200 is driven to move upwards along the second side 1022, so that the cleaning assembly 200 is raised from the folded position to the elevated posture (obstacle avoidance position) to avoid the obstacle, i.e., as shown in Figure 15 so that the cleaning device can operate normally and improve user experience. At this time, the guide protrusion on the driving part 301 of the power assembly 300 is arranged at the bottom of the first recess 2021. When the cleaning assembly 200 is switched from the elevated posture to the folded position, the power member 303 of the power assembly 300 is controlled to rotate reversely, the driving part 301 of the power assembly 300 is reversely rotated, and the guide protrusion on the driving part 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 1022 to the folded position.
