[0052] The utility model provides a kind of sweeper 100, specifically, please refer to Figure 1 And Figure 2In the embodiment, the sweeper 100 comprises a device body 1, a main cleaning brush (not shown in the drawings) and side cleaning brushes 3; the main cleaning brush is arranged at the bottom of the device body 1; the side cleaning brushes 3 are movably arranged on the device body 1 and have first positions and second positions; when in the first positions, the side cleaning brushes 3 are accommodated in the device body 1 or arranged in close contact with the device body 1; when in the second positions, at least part of the side cleaning brushes 3 can extend out of the device body 1 to be suitable for cleaning vertical wall surfaces opposite the circumferential side of the device body 1.

[0053] In the embodiment, the main cleaning brush is arranged at the bottom of the device body 1 to clean surfaces (such as floors, tabletops, etc.) opposite the bottom of the device body 1, and the side cleaning brushes 3 are arranged to clean surfaces (such as walls, skirting lines, etc.) opposite the circumferential side of the device body 1. Moreover, the side cleaning brushes 3 are movably arranged, and when the sweeper 100 normally performs cleaning work, for example, when the sweeper 100 does not clean along the edge, the side cleaning brushes 3 can be in the first positions in which the side cleaning brushes 3 are accommodated in the device body 1 or arranged in close contact with the device body 1, so that the side cleaning brushes 3 do not collide with external objects when the sweeper 100 normally performs cleaning work, and the side cleaning brushes 3 are better protected. When the sweeper 100 performs edge cleaning work, the side cleaning brushes 3 can be in the second positions in which at least part of the side cleaning brushes 3 protrude from the circumferential side of the device body 1, so that at least part of the side cleaning brushes 3 is opposite the circumferential wall of the device body 1, thereby being suitable for cleaning vertical wall surfaces opposite the circumferential side of the device body 1, that is, the cleaning of low wall surfaces such as walls or skirting lines can be realized, the sweeper 100 has more powerful functions, the labor intensity of the user can be effectively reduced, and the user experience can be improved.

[0054] In combination with the directions shown in Figure 2 It should be noted that when the sweeper 100 normally travels on the ground to perform cleaning work, the forward direction of the sweeper 100 is the front of the device body 1, the backward direction of the sweeper 100 is the rear of the device body 1, and the lower side (i.e., the bottom) of the sweeper 100 is the side facing the ground. The circumferential wall of the device body 1 can refer to the side wall connected between the top wall and the bottom wall of the device body 1, and when the device body 1 is arranged in a substantially circular shape, the circumferential wall of the device body 1 refers to the wall arranged along the circumference of the device body 1. In the present utility model, the description of the directions can be used as a reference unless otherwise specified. The following will be described by taking the example of the sweeper 100 traveling on the ground to work.

[0055] The main cleaning brush comprises a rolling brush, which is arranged at the bottom of the device body 1 and extends along the lateral direction of the device body 1. The side cleaning brush 3 is arranged close to the edge of the device body 1 and close to one end of the rolling brush, so that the structure is more compact.

[0056] For the device body 1, the device body 1 comprises a shell, the main cleaning brush is arranged in the shell and can be at least partially extended from the bottom cleaning opening of the shell, so that the main cleaning brush can be in contact with the ground to clean. The side cleaning brush 3 is arranged in the shell and is arranged higher than the bottom surface of the device body 1, so that the side cleaning brush 3 does not interfere with the ground when it is in the active switching position, and moves more smoothly.

[0057] Preferably, a displacement opening is formed on the lateral side of the device body 1, and the side cleaning brush 3 can be extended out of the device body 1 from the displacement opening. That is, when in the first position, the side cleaning brush 3 is retracted in the displacement opening and does not protrude from the device body 1, and when switched to the second position, the side cleaning brush 3 can be extended out of the device body 1 from the displacement opening, so that at least part of the side cleaning brush 3 can be located outside the lateral side of the shell. Moreover, when in the second position, the side cleaning brush 3 has a cleaning surface that is outward and arranged in the vertical direction, which cleans the vertical wall surface (such as a wall surface) opposite the outer lateral side of the shell.

[0058] Moreover, the side cleaning brush 3 has an active stroke around its own central axis, that is, the side cleaning brush 3 can rotate, so that when cleaning the vertical wall surface, the side cleaning brush 3 can roll and rub the vertical wall surface, and the cleaning effect is better. The side cleaning brush 3 can be rotated under the friction of the vertical wall surface, or the side cleaning brush 3 can be driven to rotate by a rotating driver, so as to achieve better active cleaning.

[0059] Further, the central axis of the side cleaning brush 3 extends in the up-down direction of the device body 1, so that the cleaning area of the side cleaning brush 3 can be larger and the cleaning efficiency on the vertical wall surface is higher.

[0060] Preferably, the height of the side cleaning brush 3 is adapted to the height of the device body 1. The height of the side cleaning brush 3 is not too high to affect the passing height of the cleaning robot 100 when it normally performs cleaning work, and the height of the side cleaning brush 3 is not too low to make the cleaning area too small. Preferably, the height of the side cleaning brush 3 is consistent with the height of the device body 1, so that the cleaning efficiency of the side cleaning brush 3 on the vertical wall surface is higher, and the overall height of the cleaning robot 100 is not increased, which ensures that the cleaning robot 100 can better clean low areas.

[0061] When the side cleaning brush 3 is in the rotating arrangement, preferably, the side cleaning brush 3 is adapted to form a line-surface contact with the vertical wall surface, which can ensure the rolling cleaning effect and reduce the rotating friction between the side cleaning brush 3 and the vertical wall surface, so that the travel resistance of the sweeping machine 100 is smaller and the cleaning efficiency is higher.

[0062] Preferably, as shown in Figure 3 The cross section of the side cleaning brush 3 is in a circular arrangement, that is, the side cleaning brush 3 is in a substantially cylindrical arrangement, and the side cleaning brush 3 extends in the axial direction of the device body 1. When the side cleaning brush 3 is in the second position, the cylindrical side of the side cleaning brush 3 is tangentially arranged with the vertical wall surface, and when the sweeping machine 100 travels, the side cleaning brush 3 rolls and rubs with the vertical wall surface, thereby cleaning the vertical wall surface.

[0063] Preferably, the axial direction of the side cleaning brush 3 is perpendicular to the axial direction of the main cleaning brush, and the cleaning surface of the main cleaning brush is in contact with the ground to clean a large area of the ground. At the same time, the cleaning surface of the side cleaning brush 3 is perpendicular to the ground to clean a large area of the vertical wall surface efficiently.

[0064] It should be noted that the vertical wall surface referred to in the present application includes but is not limited to a wall surface perpendicular to the ground, and also includes a slightly inclined wall surface, and can also include an arc-shaped wall surface, a concave-convex wall surface, etc., such as the side surface of a table leg and the side surface of a chair leg.

[0065] In addition, as shown in Figure 3 The sweeping machine 100 further comprises two cloth discs 4 rotatably arranged at the bottom of the device body 1, and the two cloth discs 4 are arranged in sequence in the lateral direction of the device body 1. Specifically, the two cloth discs 4 are arranged side by side in the left-right direction of the device body 1, and the side cleaning brush 3 is arranged close to the edge of one of the two cloth discs 4. The main cleaning brush and the two cloth discs 4 are arranged in sequence in the front-rear direction of the device body 1. When the sweeping machine 100 is cleaning, the main cleaning brush located at the front side first rolls up the dirt on the ground to be sucked into the interior of the sweeping machine 100, and then the two cloth discs 4 located at the rear side wet mop the cleaned ground, realizing the integration of sweeping and mopping, and the cleaning effect of the sweeping machine 100 is better. Preferably, the side cleaning brush 3 is arranged close to the right side of the device body 1, and in the front-rear direction of the device body 1, the side cleaning brush 3 is located between the main cleaning brush and the two cloth discs 4. Since the side cleaning brush 3 is used to clean the wall surface around the device body 1, it will not interfere with the main cleaning brush and the cloth disc 4, and at the same time, the structure is more compact.

[0066] Further, the rotation planes of the two mopping pads 4 and the rotation plane of the side cleaning brush 3 are arranged in parallel and spaced apart along the up-down direction of the device body 1, that is, the two mopping pads 4 and the side cleaning brush 3 are not at the same plane height, and the side cleaning brush 3 is arranged at a higher height on the device body 1 than the arrangement height of the two mopping pads 4, so that the two mopping pads 4 can better contact the ground, and the side cleaning brush 3 can better clean the vertical wall surface, and in space, the structure between the two mopping pads 4 and the side cleaning brush 3 is more compact without interference.

[0067] Further, the height of the side cleaning brush 3 along the up-down direction of the device body 1 is greater than the height of each mopping pad 4 along the up-down direction of the device body 1. Since the mopping pad 4 is located at the bottom of the device body 1, the height of the mopping pad 4 is smaller, so that the height of the entire sweeping robot 100 can be smaller, and the sweeping robot 100 can be more suitable for cleaning low spaces; and the height of the side cleaning brush 3 is relatively higher, so that the cleaning surface of the side cleaning brush 3 is larger, and the cleaning efficiency for the vertical wall surface is also higher when edge cleaning is performed, and the wall can be cleaned to a higher position.

[0068] It can be understood that, when the sweeping robot 100 performs edge cleaning, in order to enable the side cleaning brush 3 to better clean the vertical wall surface, the side cleaning brush 3 should be arranged in the vertical direction in the second position, so that the contact area with the vertical wall surface is larger and the cleaning effect is better. When in the first position, the side cleaning brush 3 should be retracted into the device body 1 to occupy as little space as possible. Therefore, when the side cleaning brush 3 switches between the first position and the second position, the moving mode of the side cleaning brush 3 is various. For example, when the side cleaning brush 3 is in a cylindrical shape, the arrangement direction of the axial direction of the side cleaning brush 3 can be the same or different in the first position and the second position. For example, in the first position, the axial direction of the side cleaning brush 3 can be arranged in the horizontal direction, and in the second position, after the side cleaning brush 3 is extended out of the shell, the direction of the side cleaning brush 3 can be switched again, so that the axial direction of the side cleaning brush 3 is arranged in the vertical direction. Further, the side cleaning brush 3 includes but is not limited to extending out or retracting from the lateral side of the device body 1. For example, when moving from the first position to the second position, the side cleaning brush 3 can first move downward, extend out of the bottom of the device body 1, then move in the horizontal direction to extend out of the lateral side of the device body 1, and finally switch the direction of the axial length of the side cleaning brush 3 to ensure that the axial direction of the side cleaning brush 3 is in the vertical state. The moving mode of the side cleaning brush 3 is flexible and various, and can be reasonably arranged according to the actual size and internal structure of the sweeping robot 100.

[0069] Further, when the side cleaning brush 3 switches between the first position and the second position, the side cleaning brush 3 can be actively moved, or the side cleaning brush 3 can be passively moved under the action of an external force.

[0070] When the side cleaning brush 3 is in active movement, the sweeping machine 100 further comprises a switching driving structure 5 connected with the side cleaning brush 3, for driving the side cleaning brush 3 to switch between the first position and the second position. The movement of the side cleaning brush 3 is driven by the switching driving structure 5, so that the movement of the side cleaning brush 3 is more intelligent and the activity is more easily controlled.

[0071] In an embodiment, the first position and the second position can be arranged along a straight line. Specifically, the switching driving structure 5 can comprise a telescopic rod and a side driver connected with the telescopic rod, the telescopic rod connecting the side driver and the side cleaning brush 3, and the side driver driving the telescopic rod to move in extension and retraction, thereby driving the side cleaning brush 3 to move. The side driver can be provided as a driving cylinder, at least one telescopic section of the telescopic rod is driven by the driving cylinder to move, so as to change the length of the telescopic rod and drive the side cleaning brush 3 to move. The extension and retraction direction of the telescopic rod should be consistent with the movement direction of the side cleaning brush 3. Preferably, the extension and retraction direction of the telescopic rod is arranged along the left-right direction of the device body 1, and the side cleaning brush 3 moves along the left-right direction of the device body 1 to switch between the first position and the second position. The side cleaning brush 3 can better achieve the cleaning work of the vertical wall surface, and the side cleaning brush 3 can also better fit the device body 1 or be arranged in the device body 1.

[0072] Preferably, the first position and the second position are arranged along an arc line. Specifically, as shown in Figure 4 The switching driving structure 5 comprises a switching driver 51 and a swing structure 52, the switching driver 51 is arranged on the device body 1, the swing structure 52 connects the switching driver 51 and the side cleaning brush 3, and the switching driver 51 drives the swing structure 52 to rotate, thereby driving the side cleaning brush 3 to switch between the first position and the second position. Through the rotation of the swing structure 52, the side cleaning brush 3 generates a stroke along the left-right direction of the device body 1 while requiring less activity space, thereby saving space and keeping the volume of the sweeping machine 100 smaller.

[0073] Further, in combination with Figure 4As shown, the swing structure 52 includes a swing rod 521 and a mounting groove 522 located at one end of the swing rod 521. A switching driver 51 is connected to the other end of the swing rod 521 to drive the swing rod 521 to rotate. The side cleaning brush 3 is rotatably disposed within the mounting groove 522 and is at least partially exposed from the mounting groove 522. The switching driver 51 can be configured as a drive motor, which drives the swing rod 521 to rotate, thereby causing the mounting groove 522 to rotate as well. The swing rod 521 is arranged in a horizontal direction. During the rotation of the swing rod 521, it can generate a movement stroke in the left-right direction along the main body 1, thereby allowing the side cleaning brush 3 to generate a movement stroke in the left-right direction along the main body 1, thus switching between a first position and a second position.

[0074] Furthermore, the side cleaning brush 3 is rotatably mounted on the swing structure 52, specifically rotatably mounted in the mounting groove 522. The mounting groove 522 covers the outer periphery of the side cleaning brush 3, so that the side of the side cleaning brush 3 facing the main body 1 can be isolated by the mounting groove 522, preventing dirt on the side cleaning brush 3 from falling onto the main body 1 when the side cleaning brush 3 is rotating.

[0075] Preferably, combined with Figure 4 and Figure 5 As shown, the shape of the mounting groove 522 matches the shape of the side cleaning brush 3, and one side of the mounting groove 522 is open, allowing the side cleaning brush 3 to extend from the open side of the mounting groove 522. The side cleaning brush 3 is generally cylindrical, and the mounting groove 522 is generally cylindrical. The side cleaning brush 3 is located inside the mounting groove 522, with the groove opening facing upwards and the bottom of the mounting groove 522 facing the opposite side of its opening. In the second position, the open side of the mounting groove 522 faces outwards from the device body 1, and the peripheral sidewall of the mounting groove 522 is not a complete circle. This allows the cleaning surface of the side cleaning brush 3 to be better exposed from the open side of the mounting groove 522 and to contact the vertical wall surface. Furthermore, the peripheral sidewall of the mounting groove 522 isolates the side cleaning brush 3 from the device body 1, better preventing dirt generated by the side cleaning brush 3 during operation from falling onto the device body 1, thus better protecting the device body 1 from contamination.

[0076] Furthermore, the side cleaning brush 3 includes a brush shaft 31 and a brush head 32 sleeved on the outside of the brush shaft 31. An installation part 523 is provided in the installation groove 522, and a mating part 311 is provided on the brush shaft 31. The installation part 523 and the mating part 311 form an anti-rotation fit to install the brush shaft 31 in the installation groove 522. The brush head 32 is rotatably sleeved on the outside of the brush shaft 31, so that the side cleaning brush 3 can be quickly installed and removed from the swing structure 52, and the side cleaning brush 3 is easier to clean and maintain.

[0077] Preferably, the mounting portion 523 comprises a limiting groove 5231 arranged on the groove bottom of the mounting groove 522, the fitting portion 311 comprises a clamping protrusion 3111 arranged on the bottom of the brush shaft 31, the clamping protrusion 3111 is clamped in the limiting groove 5231, so that the side cleaning brush 3 is mounted and limited in the mounting groove 522 of the swing structure 52. Moreover, the clamping protrusion 3111 and the limiting groove 5231 are both arranged in a non-circular shape, after the clamping protrusion 3111 is clamped in the limiting groove 5231, the brush shaft 31 cannot rotate relative to the mounting groove 522, and the limiting effect is better.

[0078] In other embodiments, when the side cleaning brush 3 is passively moved, specifically, the sweeper 100 further comprises a resilient member, the resilient member connects the side cleaning brush 3 and the device main body 1, so that the side cleaning brush 3 can be switched between the first working state and the second working state. Wherein, the resilient member can be arranged as a telescopic spring or a torsional spring member. The telescopic spring can realize the linear reciprocating movement of the side cleaning brush 3. The torsional spring member can realize the rotation of the side cleaning brush 3. Specifically, the device main body 1 and the side cleaning brush 3 are connected by the telescopic spring, and the telescopic spring is arranged in the left-right direction of the device main body 1, and the telescopic movement of the telescopic spring enables the side cleaning brush 3 to have a certain amount of reciprocating movement space in the left-right direction of the device main body 1. And under the action of the telescopic spring or the torsional spring member, when the external wall or obstacle blocks the side cleaning brush 3 on the travel path of the sweeper 100, the spring can be compressed or the torsional spring member can be pushed to twist under the action of the pushing force of the external wall or obstacle, to drive the side cleaning brush 3 to passively move to be arranged closer to the device main body 1 to form an avoidance, so as to avoid collision; and when cleaning the wall, the telescopic spring or the torsional spring member can press the side cleaning brush 3 tightly against the wall, the cleaning friction is larger, and the cleaning effect is better.

[0079] The utility model also provides a kind of sweeper 100, and the sweeper 100 in the specific embodiment in the present application can be the sweeper 100 in the above embodiment, and it can also be other sweeper 100 different from the above specific embodiment.
