It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0034] See also Figure 1 As shown, according to an embodiment of the present application, a cleaning device is provided, which may be, for example, a floor scrubber, a vacuum cleaner, or a cleaning system having a floor scrubber or a vacuum cleaner.

[0035] Specifically, the cleaning device in this embodiment includes a cleaning component 200, a dust collection pipe 500, a mobile station 300 and a base station 400. The cleaning component 200 is connected to the mobile station 300 through the dust collection pipe 500, and the mobile station 300 is provided with a sewage tank 310, a clean water tank, a water supply system and other structures to facilitate water supply to the cleaning component 200 or sewage collection and treatment, etc. The base station 400 is used to charge the mobile station 300, treat sewage, supply water and other operations.

[0036] Combination Figures 1 to 5 As shown, in order to improve the cleaning ability of the cleaning assembly 200 of this embodiment on the ground or table, the structure of the cleaning assembly 200 is designed in this embodiment. Specifically, the cleaning assembly 200 of this embodiment includes a main body 110, a swing assembly 120 and a cleaning component 210.

[0037] Among them, a cleaning component 210 is arranged on the main body 110, and the cleaning component 210 includes a mounting bracket 211 and a rotatable cleaning component 212; the swing assembly 120 is installed on the main body 110, and the swing assembly 120 includes a swing motor 121, a gear 122 and a rack 123, and the above-mentioned gear 122 is sleeved on the output shaft of the swing motor 121, the rack 123 is meshed with the gear 122 and swings under the drive of the swing motor 121, and the rack 123 is fixedly connected to the cleaning component 212.

[0038] Since the cleaning assembly 200 in this embodiment is provided with a swing assembly 120, when the swing motor 121 of the swing assembly 120 rotates, the gear 122 can be driven to rotate, and then the rack 123 and the cleaning member 212 connected to the rack 123 can be driven to swing. That is, when the cleaning assembly 200 is working, the cleaning member 212 can not only rotate but also swing, so as to effectively clean the stubborn substances attached to the ground or the table.

[0039] It can be understood that the swing motion in this embodiment is a linear motion. Figure 2 and Figure 3 When the cleaning assembly 200 is working, the swing motor 121 can be controlled to rotate forward or reversely in combination with the control program, thereby driving the rack 123 to swing back and forth along the Y direction, thereby finally achieving the purpose of driving the cleaning member 212 to swing.

[0040] Illustratively, the stains in this embodiment include but are not limited to water stains, oil stains, rice, mud, coffee stains, and the like.

[0041] Furthermore, the swing assembly 120 in this embodiment further includes a rack frame 124, on which a receiving cavity 1241 is provided, the gear 122 is provided in the receiving cavity 1241 and sleeved on the output shaft of the swing motor 121, and the rack 123 is movably provided on the rack frame 124. In this embodiment, the rack frame 124 is provided to support and install the gear 122 and the rack 123, so that the connection stability of the entire structure can be improved, and it is more convenient to realize the integrated and modular design of the swing assembly 120, and the structure is simple and easy to install.

[0042] In addition, in this embodiment, by arranging the gear 122 in the accommodating cavity 1241, the gear 122 can be protected to prevent other substances from interfering with the normal operation of the gear 122. During actual installation, the gear 122 is installed on the output shaft of the swing motor 121 through the first bearing 140.

[0043] In the present application, the rack frame 124 is disposed on the main body 110 and fixedly connected to the housing of the swing motor 121, and the accommodating cavity 1241 is disposed on a side of the rack frame 124 close to the swing motor 121. Specifically, the bottom of the rack frame 124 is fixed to the main body 110 by a first screw 160, and then the side close to the swing motor 121 is fixedly connected to the housing of the swing motor 121 by a second screw 170, which has a simple structure and is stable and reliable.

[0044] Of course, in other embodiments of the present application, the rack frame 124 can also be connected to the main body 110 and the swing motor 121 by means of snaps, pins, rivets or welding. As long as it is other deformation methods based on the concept of the present application, it is within the protection scope of the present application.

[0045] In order to facilitate the installation of the rack 123, the rack frame 124 in this embodiment is provided with a long groove 1242. During actual installation, the rack 123 is movably installed in the long groove 1242, and the moving direction of the rack 123 is consistent with the length direction of the long groove 1242. In this way, when the swing motor 121 is working, the gear 122 can be driven to rotate and drive the rack 123 to move in the long groove 1242, and finally drive the cleaning member 212 connected to the rack 123 to swing.

[0046] Optionally, the long groove 1242 in this embodiment can be set on the top, bottom or side wall of the rack frame 124. Figure 4 and Figure 5 1 shows a method of setting the long groove 1242 at the bottom of the rack rack 124. The long groove 1242 may be, for example, a dovetail groove, and correspondingly, the rack 123 is provided with a connection portion adapted to the dovetail groove; the long groove 1242 may also be, for example, a groove whose width is constant in the depth direction, and a limit projection or a limit groove or the like is provided on the groove wall of the long groove 1242 (such as the structure of the present application). Figure 4 and Figure 5 As shown in ), correspondingly, the rack 123 is provided with a recessed or raised portion adapted to the limiting protrusion or limiting groove, so that the connection stability between the rack 123 and the rack frame 124 can be improved.

[0047] In this embodiment, the long groove 1242 is arranged on the rack frame 124, and correspondingly, at least one end of the rack 123 is provided with a limiting portion 1231. The drawings of this application show the situation that both ends of the rack 123 are provided with limiting portions 1231. In the projection of the long groove 1242 in the length direction, the limiting portion 1231 at least partially protrudes from the contour line of the side wall of the long groove 1242. In this way, when the rack 123 moves along the length direction of the long groove 1242, the limiting portion 1231 can stop at the end of the long groove 1242 to prevent the rack 123 from falling from the long groove 1242. In other words, when the rack 123 moves to the farthest end, the travel of the rack 123 can be limited by the limiting portion 1231.

[0048] Optionally, the limiting portion 1231 may be a limiting block, a limiting column or other structures. As long as other deformation modes can limit the stroke of the rack 123 , they are all within the protection scope of the present application.

[0049] Furthermore, a detection element (not shown in the figure) is provided on the limit portion 1231, and the detection element is at least used to detect the distance between the limit portion 1231 and the rack frame 124. The detection element can be, for example, a proximity switch, or other displacement sensors. In this embodiment, the detection element is provided on the limit portion 1231 to detect the distance between the limit portion 1231 and the rack frame 124, which is more suitable for the control program to control the rotation direction of the swing motor 121, and can improve the stability of the cleaning component 200 in this embodiment when working. Exemplarily, when the rack 123 moves along the long groove 1242 and the detection element detects that the distance between the limit portion 1231 and the rack frame 124 is less than a preset value, the control program is used to control the swing motor 121 to switch the rotation direction.

[0050] For example, when the swing motor 121 drives the rack 123 to move to Figure 6 When the rack 123 is at the left end of the long slot 1242, the cleaning member 212 can be driven to move toward the left side of the main body 110. When the swing motor 121 drives the rack 123 to move to Figure 7 When the rack 123 is in the middle position of the long slot 1242, the cleaning member 212 can be driven to move to the middle of the main body 110. Figure 8 When the cleaning member 212 is in the middle position, the rack 123 slides along the long groove 1242 to the right side of the long groove 1242 , and at this time, the cleaning member 212 can be driven to move toward the right side of the main body 110 .

[0051] According to the above motion process, it can be known that when the swing motor 121 in this embodiment rotates forward and reversely, the rack 123 can be driven to swing back and forth along the Y direction, and then the cleaning member 212 can be driven to swing back and forth. In this way, when the cleaning member 212 rotates, it can swing along the Y direction at the same time, which can effectively clean the stains on the floor or table, and facilitate the removal of stubborn stains on the floor or table.

[0052] Furthermore, during the actual connection, the mounting bracket 211 is fixedly connected to the rack 123, and the swing assembly 120 further includes a swing bearing 125 and a swing shaft 126. The swing bearing 125 is fixedly mounted on the mounting bracket 211; the swing shaft 126 is fixedly mounted on the main body 110, and the swing shaft 126 is inserted into the swing bearing 125, and the axis of the swing shaft 126 is consistent with the swing direction of the rack 123. In this way, when the swing motor 121 rotates, the mounting bracket 211 can be driven to slide along the swing shaft 126. The setting of the swing shaft 126 can provide stable support for the mounting bracket 211, which is convenient for stably connecting the cleaning component 210 to the rack 123, and can improve the stability and reliability of the cleaning component 210 during movement.

[0053] Optionally, in order to improve the working stability of the cleaning component 210 in this embodiment, multiple swing shafts 126 can be provided to support the mounting bracket 211. For example, the swing shaft 126 can be one, two, or more than two. Figure 3 2 shows the situation when the mounting bracket 211 is sleeved on the two swing shafts 126.

[0054] Furthermore, the outer peripheral surface of the swing bearing 125 in this embodiment at least partially has a concave-convex surface 1251 , and the swing bearing 125 is embedded in the mounting bracket 211 and meshed with the mounting bracket 211 through the swing bearing 125 , so the structure is more stable and reliable.

[0055] In order to further improve the installation stability of the cleaning component 210, the cleaning assembly 200 in this embodiment further includes a support shaft 250 and a second bearing 260. The support shaft 250 is installed on the main body 110, and the second bearing 260 is embedded in the mounting bracket and sleeved on the outer periphery of the support shaft 250. When the cleaning component 210 moves with the rack 123, the cleaning component 210 moves along the support shaft 250 together, and the entire structure is more stable and reliable. Figures 1 to 7 As shown, the swing assembly 120 in this embodiment also includes a motor bracket 127, which is fixedly connected to the positioning column 1101 on the main body 110 through a third screw 180, so that the swing motor 121 can be locked on the main body 110. The structure is simple and easy to implement. In order to reduce the vibration of the swing motor 121, a shock-absorbing pad or other structure can also be set at the position where the motor bracket 127 is connected to the positioning column 1101.

[0056] Furthermore, the cleaning member 212 in this embodiment can be a roller brush or a flat mop structure. The drawings of this application show the situation when the cleaning member 212 is a roller brush. In this embodiment, the roller brush can rotate around its own axis to perform cleaning operations. The swing direction of the rack 123 is parallel to the axis of the roller brush. Of course, in other embodiments of this application, the swing direction of the rack 123 can also intersect with the axis of the roller brush.

[0057] Combination Figures 1 to 5 As shown, the cleaning assembly 200 in this embodiment further includes a first rolling portion 220, which is disposed at the bottom of the cleaning component 210. During actual installation, the cleaning component 210 is installed on the first side of the main body 110, so that when the swing motor 121 drives the cleaning component 210 to swing along the Y direction, the first rolling portion 220 can assist the movement of the cleaning component 210, which can effectively reduce the energy consumption of the swing motor 121 in this embodiment.

[0058] Exemplarily, the first rolling portion 220 in this embodiment includes at least one universal wheel, and the at least one universal wheel is disposed at the bottom of the cleaning component 210. Optionally, the universal wheel can be provided as one, or two, three, or more than three. Figure 3 and Figure 4 The figure shows the situation when there are two universal wheels. The two universal wheels can cooperate with the position where the cleaning component 210 is connected to the swing assembly 120 to form a triangular support structure, which can not only assist the movement of the cleaning component 210 during its movement, but also provide stable support for the cleaning component 210.

[0059] In this embodiment, the universal wheel is surrounded by soft glue (rubber, silicone), so that when the swing motor 121 drives the cleaning component 210 to swing, it can play a supporting role. The universal wheel supports the rear end of the cleaning component 210 (the end away from the main body 110), which can prevent the cleaning component 210 from tilting toward the rear end of the cleaning component 210 due to lack of support, thereby increasing the friction during swinging, causing the swing motor 121 to have an excessive current, freeze or overload protection. In addition, the universal wheel can follow the cleaning component 210 when it swings left and right, ensuring the smoothness of the left and right swinging operation of the cleaning component 210.

[0060] Furthermore, the cleaning assembly 200 in this embodiment also includes a second rolling portion 230, which is disposed at the bottom of the main body 110. Through the action of the second rolling portion 230, the entire cleaning assembly 200 is facilitated to move in the space to perform cleaning operations.

[0061] Optionally, the second rolling portion 230 in this embodiment includes a driving wheel set 231 and an auxiliary wheel set 232, wherein the driving wheel set 231 is arranged on the second side 1103 of the main body 110 opposite to the first side 1102, and the auxiliary wheel set 232 is arranged at the bottom of the main body 110 close to the first side 1102. In actual operation, the driving wheel set 231 provides power for the movement of the main body 110, and the auxiliary wheel set 232 assists the driving wheel set 231 in driving the main body 110 to move. At the same time, the driving wheel set 231 and the auxiliary wheel set 232 are respectively arranged on opposite sides of the main body 110, so as to provide stable support for the main body 110.

[0062] Furthermore, one of the driving wheel set 231 and the auxiliary wheel set 232 in this embodiment includes at least one first roller, and the other includes at least two second rollers, wherein the axes of the first roller and the second roller are parallel to each other, and at least three of the first roller and the second roller are arranged in a triangle. Such an arrangement is not only convenient for driving the main body 110 to move, but also convenient for stably supporting the main body 110.

[0063] For example, in the present embodiment, when there are two first rollers and two second rollers, they can be selected and designed according to actual usage requirements, and are not specifically limited in the present application.

[0064] In this embodiment, an auxiliary wheel group 232 is added to the side of the main body 110 close to the cleaning component 210. The auxiliary wheel group 232 is surrounded by soft glue (rubber, silicone), so as to support the first side 1102 of the main body 110, so that the ground of the main body 110 remains parallel to the ground, and ensures the balance of the output shaft of the swing motor 121 on the main body 110 and the installation of the main body 110. The main body 110 does not tilt on one side due to its own weight, which solves the problem of increased swing friction. At the same time, it increases the ground friction together with the active wheel group 231, ensuring that the cleaning component 200 has strong friction and adheres to the ground when swinging, thereby ensuring stable swing output.

[0065] Furthermore, in this embodiment, the outer diameter of the first roller is larger than the outer diameter of the second roller, the overall size of the rear wheel is 50mm-65mm in diameter, and the outer ring surrounds the soft tire (rubber, silicone) and the friction surface adopts a trapezoidal convex bulge design with the middle hollowed out to ensure a certain pressing elasticity of the rear wheel as a whole, increase the ground friction, and ensure the swing output stability of the cleaning component 210.

[0066] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0067] In addition, it should be noted that the use of words such as "first" and "second" to limit components is only to facilitate the distinction between corresponding components. If not otherwise stated, the above words have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0068] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
