[0065] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0066] Floor cleaning is an important part of cleaning activities. With the development of cleaning equipment, the application of cleaning equipment such as floor scrubbers that integrate dust collection and floor washing functions is becoming more and more widespread. Floor scrubbers are generally provided with a base and a roller brush assembly arranged adjacent to each other. The dust suction port of the base is generally provided on the side of the base close to the roller brush assembly. In the prior art, since the roller brush assembly and the dust suction port are arranged adjacent to each other, the gap between the roller brush assembly and the dust suction port is relatively small. On the one hand, garbage easily clogs the gap between the roller brush assembly and the base. On the other hand, when garbage clogs the dust suction port, the dust suction port needs to be cleaned. When cleaning the garbage in the gap between the roller brush assembly and the base and the garbage clogged in the dust suction port, since the roller brush assembly is generally large in size, it is relatively cumbersome to disassemble the roller brush assembly when cleaning the clogged garbage from the side of the base close to the roller brush assembly. In addition, the roller brush assembly often blocks the dust suction port, which greatly increases the difficulty of cleaning the floor scrubber and seriously affects the convenience of using the equipment.

[0067] To solve the above problems, as shown in Figures 1 to 12, the present application provides a cleaning mechanism 100, which includes a base 110, a roller brush assembly 120 and a connecting assembly 130.

[0068] As shown in Figures 9 and 10, the base 110 has a first end surface 111, and the first end surface 111 is provided with a dust suction port 112. The dust suction port 112 is used to clean and collect garbage.

[0069] As shown in Figures 1 and 6 , the roller brush assembly 120 has a first outer peripheral wall 121. The roller brush assembly 120 is located opposite the base 110 on a side where the dust suction port 112 is located. The dust suction port 112 is used for garbage collection. As shown in Figures 2 and 3 , the connecting assembly 130 has a first connecting end 131 and a second connecting end 132. The first connecting end 131 is connected to the base 110, and the second connecting end 132 is connected to the roller brush assembly 120. The cleaning mechanism 100 can be movably connected to the base 110 only by the first connecting end 131, only by the second connecting end 132, or both by the first connecting end 131 and the second connecting end 132. In practice, the first connecting end 131 can be connected to the base 110 using any suitable method. Specifically, the first connecting end 131 can be connected to the base 110 using a hinge connection or a sliding connection. Likewise, the second connection end 132 may be connected to the base 110 in any suitable manner. Specifically, the second connection end 132 may be connected to the roller brush assembly 120 by a hinge connection or a sliding connection.

[0070] As shown in Figures 6, 7, 8, and 9, the roller brush assembly 120 has a first position proximate to the first end surface 111 and a second position distal thereto. The first connecting end 131 is movably connected to the base 110, and the second connecting end 132 is movably connected to the roller brush assembly 120, enabling the roller brush assembly 120 to move from the first position to the second position. In the first position, the roller brush assembly 120 is located on a side of the base 110 where the dust suction port 112 is located, and is arranged opposite the base 110. When the roller brush assembly 120 is in the first position, the dust suction port 112 can absorb and recycle garbage, and the roller brush assembly 120 can clean contact surfaces such as the ground. During the cleaning process, if garbage becomes blocked between the dust suction port 112 and the roller brush assembly 120, the roller brush assembly 120 switches from the first position to the second position relative to the base 110 to clear the blocked garbage. In the second position, a cleaning operation space 113 is defined between the roller brush assembly 120 and the first end surface 111. That is, in the second position, the roller brush assembly 120 moves toward the side away from the first end surface 111, and a cleaning operation space 113 is defined between the roller brush assembly 120 and the dust suction port 112. This allows the roller brush assembly 120 to reduce obstruction of the dust suction port 112, exposing the dust suction port 112 and making it easier to comb the dust suction port 112. It should be noted that in some embodiments, the roller brush assembly 120 can be driven by the connecting assembly 130 to move from the first position to the second position, or the roller brush assembly 120 can be driven by the connecting assembly 120 to move, which is not limited here.

[0071] In the technical solution of the present application, the base 110 has a first end surface 111, which is provided with a dust suction port 112. The roller brush assembly 120 has a first outer peripheral wall 121. The roller brush assembly 120 is arranged opposite the base 110, and a cleaning operation space 113 is defined between the first outer peripheral wall 121 and the first end surface 111. The connecting assembly 130 has a first connecting end 131 and a second connecting end 132. The roller brush assembly 120 has a first position close to the first end surface 111 and a second position farther away from the first end surface 111. The first connecting end 131 is connected to the base 110, and the second connecting end 132 is connected to the roller brush assembly 120. The connecting assembly 130 enables the roller brush assembly 120 to move from the first position to the second position, thereby forming the cleaning operation space 113. The provision of the cleaning operation space 113 greatly improves the convenience of the user in cleaning the dust suction port 112, making it easier to remove debris between the roller brush assembly 120 and the dust suction port 112. The technical solution of the present application can improve the convenience of cleaning the dust suction port 112 of the cleaning mechanism 100.

[0072] In some embodiments, to enable the roller brush assembly 120 to switch between the first and second positions, the connecting portion can be connected to the base 110 and the roller brush assembly 120 in any suitable manner. Specifically, the first connecting end 131 can be hingedly or slidably connected to the base 110. As shown in Figures 1, 2, and 4, in this embodiment, the first connecting end 131 is hingedly connected to the base 110, and the connecting assembly 130 can drive the roller brush assembly 120 to rotate about a first axis 122 to switch the roller brush assembly 120 between the first and second positions. The first axis 122 is parallel to the axis of the first outer peripheral wall 121. It will be understood that because the hinged end is the first connecting end 131, when the roller brush assembly 120 switches between the first and second positions, the connecting portion and the roller brush assembly 120 can rotate together about the first axis 122 as the center axis. In some embodiments, the first connecting end 131 can be slidably connected to the base 110, thereby enabling the connecting assembly 130 and the movable roller brush assembly 120 to slide simultaneously relative to the base 110.

[0073] In some embodiments, the connecting assembly 130 is hinged to the base 110. To ensure that the cleaning operation space 113 provides sufficient cleaning space for the cleaning mechanism 100 when the roller brush assembly 120 is in the second position, the hinge angle between the connecting assembly 130 and the base 110 in the second position can be much greater than the hinge angle between the connecting assembly 130 and the base 110 in the first position. It is understood that if the roller brush assembly 120 is hinged at the second connecting end 132, the hinge angle between the roller brush assembly 120 and the second connecting end 132 in the second position can also be much greater than the hinge angle between the roller brush assembly 120 and the first connecting assembly 130 in the first position. This will not be further described here. As shown in Figures 4, 6 and 8, in this embodiment, the first connecting end 131 is hinged to the base 110, and the connecting assembly 130 and the roller brush assembly 120 can rotate together around a first axis 122 parallel to the axis of the first outer peripheral wall 121, wherein the first direction X is perpendicular to the first axis 122 and points from the first connecting end 131 to the second connecting end 132, and the second direction Y is perpendicular to the first axis 122 and points from the first connecting end 131 to the dust suction port 112. In the first position, the angle between the first direction X and the second direction Y is a first hinge angle α, so that a first gap is formed between the first end face 111 and the roller brush assembly 120. In the first gap, there is a first minimum distance L1 between the dust suction port 112 and the first outer peripheral wall 121. In the second position, the angle between the first direction X and the second direction Y is the second articulation angle β, so that a cleaning operation space is formed between the first end surface 111 and the roller brush assembly 120. In the cleaning operation space, a second minimum distance L2 is defined between the suction port 112 and the first outer peripheral wall 121. The first articulation angle α and the second articulation angle β satisfy the following relationship: β ≥ 2α, and the first minimum distance L1 and the second minimum distance L2 satisfy the following relationship: L2 > L1. In other words, the articulation angle between the connecting end and the base 110 in the second position is at least twice the articulation angle between the connecting end and the base 110 in the first position. Specifically, the second articulation angle β can be 2 times the first articulation angle α, 2.5 times the first articulation angle α, 3 times the first articulation angle α, or 8 times the first articulation angle α. The multiple of the second hinge angle β and the first hinge angle α can vary depending on the diameter of the first outer peripheral wall 121 and the specific positional relationship between the roller brush assembly 120 and the base 110, and is not limited here. The connecting assembly 130 is hinged to the base 110 at the first hinge angle α, forming a first gap between the first end surface 111 and the roller brush assembly 120. The provision of this first gap can enhance the ability of the dust collection port 112 to collect waste.The connecting assembly 130 is hinged to the base 110 at a second hinge angle β, forming a cleaning operation space between the first end surface 111 and the roller brush assembly 120. In the second position, the hinge angle between the connecting assembly 130 and the base 110 is greater than the hinge angle between the connecting assembly 130 and the base 110 in the first position. This means that the second minimum distance L2 between the suction port 112 and the first peripheral wall 121 in the cleaning operation space is greater than the first minimum distance L1 between the suction port 112 and the first peripheral wall 121 in the first gap. Switching from the first hinge angle α to the second hinge angle β forms a cleaning operation space 113 between the suction port 112 and the first peripheral wall 121, further facilitating cleaning of the cleaning mechanism 100.

[0074] In some embodiments, depending on different usage requirements, the size of the second articulation angle β in the second position may be different. As shown in Figure 8, in this embodiment, the second articulation angle β satisfies: 90°≤β≤270°. Specifically, the second articulation angle β can be any angle that can form the cleaning operation space 113, such as 90°, 95°, 100°, 120°, 170°, 220° or 270°. The diameter of the first outer peripheral wall 121 of the roller brush assembly 120 remains unchanged. The larger the second articulation angle β, the larger the distance between the first outer peripheral surface and the first end face 111, that is, the larger the cleaning operation space 113. It can be understood that in some embodiments, when the second articulation angle β is greater than 90°, the roller brush assembly 120 rotates along the first direction and reveals the dust suction port 112. It can be understood that when the second articulation angle β is greater than 90°, when the second articulation angle β is any suitable angle such as 220° or 270°, the roller brush assembly 120 is flipped from the side of the base 110 where the dust suction port 112 is provided to the side of the base 110 opposite to the dust suction port 112. The base 110 can be provided with a slot for placing the roller brush assembly 120, so that the roller brush assembly 120 can be placed on the side of the base 110 opposite to the dust suction port 112 after rotation. On the one hand, β≥90° can effectively increase the spatial range of the cleaning operation space 113, which is convenient for cleaning the cleaning mechanism 100. On the other hand, the connection between the roller brush assembly 120 and the base 110 after flipping can improve the convenience of fixing the roller brush assembly 120 in the second position, thereby facilitating the cleaning of the cleaning mechanism 100.

[0075] In some embodiments, depending on different usage requirements, the second connection end 132 can be connected to the roller brush assembly 120 in different ways. To enable the roller brush assembly 120 to switch between the first and second positions, the roller brush assembly 120 can be connected to the second connection end 132 via a hinged connection or a sliding connection. The roller brush assembly 120 is hinged to the second connection end 132. Depending on different usage requirements, the direction of rotation of the roller brush assembly 120 relative to the base 110 can also vary. Specifically, the hinge axis between the roller brush assembly 120 and the second connection end 132 can be parallel to the axis of the first outer peripheral wall 121. During rotation, the connection portion can remain stationary relative to the base 110, while the roller brush assembly 120 rotates relative to the connection assembly 130 around the hinge axis on the second connection end 132. The roller brush assembly 120 can also be slidably connected to the second connection end 132, allowing it to slide from the first position to the second position during use. To further enhance the ease of connection between the roller brush assembly 120 and the connecting portion, the roller brush assembly 120 can be connected to the second connecting end 132 via a snap-fit ​​mechanism. As shown in Figures 2 and 3 , in this embodiment, the second connecting end 132 defines a first snap-fit ​​slot 1321, and the roller brush assembly 120 has a third connecting end 123 that extends through the first snap-fit ​​slot 1321, thereby connecting the roller brush assembly 120 to the connecting assembly 130. It will be appreciated that in some embodiments, the roller brush assembly 120 may define a snap-fit ​​slot, with the second connecting end 132 extending through the slot, thereby connecting the roller brush assembly 120 to the connecting assembly 130.

[0076] In some embodiments, when the roller brush assembly 120 is fixedly connected to the second connection end 132 by snapping or other means, the first connection end 131 and the base 110 can be connected by a hinge or sliding connection, so as to enable the roller brush assembly 120 to switch between the first position and the second position. In some embodiments, the first connection end 131 can be hinged to the second connection end 132, thereby enabling the roller brush assembly 120 to switch between the first position and the second position. That is, in some embodiments, the first connection end 131 can be fixedly connected to the base 110, and the roller brush assembly 120 can also be fixedly connected to the second connection end 132. The first connection end 131 and the second connection end 132 can be hinged, thereby allowing the second connection end 132 and the roller brush assembly 120 to rotate simultaneously relative to the first connection end 131 and the base 110. Similarly, the first connection end 131 can be fixedly connected to the base 110, and the roller brush assembly 120 can also be fixedly connected to the second connection end 132. The first connection end 131 and the second connection end 132 can be slidably connected, or a retractable elastic member can be provided between the first connection end 131 and the second connection end 132, so that the second connection end 132 and the roller brush assembly 120 can move from the first position to the second position.

[0077] In some embodiments, the cleaning mechanism 100 may also be provided with a plurality of connecting assemblies 130. Specifically, along a direction parallel to the axis of the first peripheral wall 121, the cleaning mechanism 100 may be provided with two oppositely arranged connecting assemblies 130, wherein one connecting assembly 130 enables one end of the roller brush assembly 120 to be hingedly connected to the base 110, and the other connecting assembly 130 enables the other end of the roller brush assembly 120 to be slidably connected to the base 110. When in use, the roller brush assembly 120 can rotate around the hinged end to form a cleaning operation space 113. The connection method between the base 110, the connecting assembly 130, and the roller brush assembly 120 can be any connection method or a combination of connection methods that can meet the implementation requirements, as long as each connection method can increase the cleaning operation space 113.

[0078] In some embodiments, to improve the convenience of cleaning the cleaning mechanism 100, when the roller brush assembly 120 moves to the second position, the roller brush assembly 120 or the connecting assembly 130 can be limited and fixed to fix the roller brush assembly 120 in the second position. After the garbage blocked between the dust suction port 112 and the roller brush assembly 120 is cleaned, the roller brush assembly 120 is released to allow the roller brush assembly 120 to switch from the second position back to the first position. As shown in Figures 3, 10, and 11, in this embodiment, the connecting assembly 130 includes a locking portion 133. The first connecting end 131 limits a second slot 1311. When the roller brush assembly 120 is in the second position, the locking portion 133 is inserted into the second slot 1311 to fix the roller brush assembly 120 in the second position. Specifically, the first connecting end 131 can be hinged to the base 110, and the second connecting end 132 can be fixedly connected to the roller brush assembly 120. The first connecting end 131 defines a second slot 1311. When the roller brush assembly 120 and the connecting assembly 130 are rotated to the second position, the locking portion 133 is inserted into the second slot 1311, thereby enabling the roller brush assembly 120 to be fixed in the second position. It is understood that in some embodiments, depending on the different connection methods between the roller brush assembly 120 and the connecting portion, the locking portion 133 can also be engaged with the second connecting end 132 to enable the roller brush assembly 120 to be fixed in the second position, and this is not limited here.

[0079] In some embodiments, to achieve locking and releasing of the connecting portion by the locking portion 133, the locking portion 133 may be provided with an elastic structure. When the roller brush assembly 120 is in the first position, the elastic structure is compressed. When the roller brush assembly 120 is in the second position, the elastic portion is released, thereby enabling the elastic structure to push the locking portion 133 into the slot provided on the connecting portion. As shown in FIG11 , in this embodiment, the locking portion 133 includes a locking end 1331 and an elastic end 1332. One side of the elastic end 1332 is connected to the base 110 and the other side is connected to the locking end 1331. The elastic end 1332 is used to enable the locking end 1331 to be inserted into the second slot 1311 when in the second position. Specifically, the base 110 can limit the accommodating chamber for installing the locking part 133, one end of the elastic end 1332 is connected to the wall of the accommodating chamber, and the other end is connected to the locking end 1331. When the roller brush assembly 120 is in the first position, the connecting part abuts against the side of the locking end 1331 away from the elastic end 1332, so that the elastic end 1332 is compressed. When the roller brush assembly 120 moves to the second position, the second slot 1311 and the locking part 133 are arranged opposite to each other, and the compression of the second slot 1311 by the connecting part is released, and the elastic end 1332 is released, so that the elastic end 1332 can push the locking end 1331 to pass through the second slot 1311, and finally the locking part 133 fixes the roller brush assembly 120 in the second position.

[0080] In some embodiments, to reduce the size of the roller brush assembly 120 while maintaining its cleaning performance, making the cleaning mechanism 100 more compact, the power structure of the roller brush assembly 120 can be placed within the roller brush housing 140. As shown in Figures 1 and 5, in this embodiment, the roller brush assembly 120 includes a roller brush portion 124 and a drive portion 125. The roller brush portion 124 defines a first accommodating cavity 1241. The drive portion 125 is positioned within the first accommodating cavity 1241 and is capable of driving the roller brush portion 124 relative to the base 110. Specifically, to achieve cleaning, the drive portion 125 includes an output shaft connected to the roller brush portion 124 to rotate the roller brush portion 124 about its axis. The drive portion 125 is placed within the roller brush portion 124, eliminating the need for the drive portion 125 to connect to the roller brush portion 124 from both ends. This eliminates the need for side edges at the ends of the roller brush portion 124 for connection to the drive portion 125. That is to say, along the direction parallel to the axis of the first outer peripheral wall 121, the roller brush portion 124 does not need to be provided with an extra frame. The driving portion 125 is arranged inside the roller brush portion 124. On the one hand, it makes the structure of the roller brush assembly 120 more compact. On the other hand, it also enhances the effective cleaning length of the roller brush assembly 120 along the direction parallel to the axis of the first outer peripheral wall 121, thereby improving the cleaning ability of the roller brush assembly 120.

[0081] In some embodiments, according to different usage requirements, one end of the connecting component 130 that can be connected to the roller brush assembly 120 can be connected to the driving portion 125, or can be connected to the roller brush portion 124. As shown in Figure 4, in this embodiment, the second connecting end 132 is connected to the driving portion 125. Specifically, the second connecting end 132 can be formed with an annular groove extending in a direction parallel to the axis of the first outer peripheral wall 121, and the driving portion 125 is inserted into the annular groove of the second connecting end 132. When cleaning the cleaning mechanism 100, the second connecting end 132 drives the driving portion 125, and the driving portion 125 drives the roller brush portion 124 connected thereto to move, thereby causing the roller brush assembly 120 to move from the first position to the second position and form a cleaning operation space 113. It should be noted that, in some implementations, in order to strengthen the connection between the roller brush assembly 120 and the base 110, the base 110 may be provided with a reinforcement component, and the reinforcement component is connected to the roller brush assembly 120. The roller brush assembly 120 can move from a first position to a second position relative to the base 110 after the reinforcement component is removed. The roller brush assembly 120 can also move from the first position to the second position before the reinforcement component is removed. There is no limitation here.

[0082] As shown in Figures 5 and 7, in some embodiments, according to different usage requirements, the roller brush portion 124 can be connected to the driving portion 125 in different ways. The roller brush portion 124 can be provided with a magnetic component, and the driving portion 125 can also be provided with a magnetic component that cooperates therewith, and the roller brush portion 124 is magnetically connected to the driving portion 125. Specifically, the magnetic component can be a magnet or any other component that meets the requirements. The roller brush portion 124 can also be snapped into the driving portion 125. Specifically, the roller brush portion 124 can be provided with an annular groove, and the driving portion 125 can be provided with a protrusion, which is passed through the annular groove, so that the roller brush portion 124 is snapped into the driving portion 125. Specifically, the driving portion 125 can include fixed parts such as a stator, a shell, etc., and movable parts such as a rotor, etc. The roller brush assembly 124 can be connected to the fixed part of the driving portion 125 in a suitable manner. It should be noted that in some embodiments, depending on the different structures of the driving part 125 and the roller brush part 124, the roller brush part 124 can be connected to the driving part 125 only by magnetic attraction or snap connection, and the roller brush part 124 can also be connected to the driving part 125 by a combination of multiple connection methods, which is not limited here.

[0083] In some embodiments, to enhance the flexibility of the roller brush unit 124 in performing cleaning operations and facilitate connection between the drive unit 125 and the roller brush unit 124, the roller brush unit 124 may be provided with multiple rollers. As shown in Figures 1 and 5, in this embodiment, the roller brush unit 124 includes a first roller 1242 and a second roller 1244. The first roller 1242 defines a first cavity 1243, and the second roller 1244 defines a second cavity 1245. The first cavity 1243 and the second cavity 1245 together form a first accommodating chamber 1241. During installation, the first roller 1242 and the second roller 1244 can be connected separately to the drive unit 125, greatly enhancing the ease of installation and use of the roller brush unit 124. It should be noted that when the roller brush assembly 120 moves from the first position to the second position, the roller brush portion 124 and the driving portion 125 can move from the first position to the second position together. To facilitate movement, the roller brush portion 124 can also be removed first, and only the driving portion 125 can be driven to move from the first position to the second position.

[0084] In some embodiments, to enhance the applicability of the cleaning mechanism 100 in various environments, the output terminal configuration of the drive unit 125 in the roller brush assembly 120 may vary depending on the number and arrangement of the roller brush sections 124 in the roller brush assembly 120. As shown in FIG1 , in this embodiment, the drive unit 125 includes a first drive member 1251 and a second drive member 1252. Parallel to the first axis 122, the second connection end 132 is connected to the first drive member 1251 on one side and to the second drive member 1252 on the other side. The first drive member 1251 is disposed in the first chamber 1243, and the second drive member 1252 is disposed in the second chamber 1245. It will be appreciated that in some embodiments, the roller brush section 124 may include three or more rollers, and the drive unit 125 may include drive members corresponding to each roller. During use, each drive member can synchronously drive the rollers to perform cleaning tasks, or each drive member can drive the rollers according to different usage requirements. The provision of multiple driving members greatly enhances the adaptability of the roller brush portion 124 to different cleaning requirements.

[0085] In some embodiments, the roller brush portion 124 may include multiple rollers, each with varying sizes and surface contact areas. As shown in Figures 7 and 9 , in this embodiment, along a direction parallel to the first axis 122, the first length d of the first roller 1242 and the second length D of the second roller 1244 satisfy the relationship d ≤ D. In some implementations, the first length d of the first roller 1242 may be ½, ¾, or ¼ of the second length D of the second roller 1244. It is understood that since the first length d of the first roller 1242 is not greater than the second length D of the second roller 1244, the first roller 1242 may preferably be connected to the connecting assembly 130 or the first roller 1242 may be connected to the second roller 1244 via a convenient method such as magnetic attraction. To enhance connection stability, the side of the second roller 1244 facing away from the first roller 1242 may also be connected to the base 110, without limitation.

[0086] In some embodiments, to enhance the stability of the connection between the drive unit 125 and the base 110 and to provide protection during use of the roller brush assembly 120, the cleaning mechanism 100 may be provided with a housing 140. As shown in FIG5 , in this embodiment, the cleaning mechanism 100 further includes the housing 140, which has a fourth connection end 141 and a fifth connection end 142. The fourth connection end 141 is connected to the base 110, and the fifth connection end 142 is connected to the end of the second driving member 1252 distal from the second connection end 132. Since one end of the second driving member 1252 is connected to the second connection end 132, the second driving member 1252 is disposed in the second chamber 1245 of the second roller body 1244, and the second length D of the second roller body 1244 is not less than the first length d of the first roller body 1242 in a direction parallel to the first axis 122, the connection of the fifth connection end 142 to the side of the second driving member 1252 distal from the second connection end 132 effectively enhances the stability of the connection of the second driving member 1252. It can be understood that in some embodiments, the fourth connection end 141 can be connected to the base 110 by means of a hinge, a sliding connection or a bolt connection, and the fifth connection end 142 can also be connected to the end of the second driving member 1252 away from the second connection end 132 by means of a hinge, a sliding connection or a bolt connection. The roller brush assembly 120 needs to move from the first position to the second position. During the movement of the roller brush assembly 120, the shell 140 can be connected to the base 110 and the roller brush assembly 120. To facilitate the movement of the roller brush assembly 120, the shell 140 can also be removed first and then the roller brush assembly 120 can be driven to make the roller brush assembly 120 move between the first position and the second position. There is no restriction here.

[0087] A floor scrubber is used to clean the floor. The floor scrubber includes a base, a motor, and a brush. In the prior art, mounting portions are provided at both ends of the base, and a mounting portion is connected to each end of the brush body to ensure a stable connection with the base. In order to save driving space between the motor and the brush body, the motor is built into the brush body. However, when cleaning blind corners on the floor, the brush body is difficult to directly reach the blind corners due to the obstruction of the mounting portion. Therefore, the existing floor scrubbers have poor cleaning effects on blind corners on the floor. In another type of floor scrubber, a single mounting portion is provided at one end of the base, and the motor has a first end and a second end relative to each other. The first end is connected to the mounting portion, and the second end is provided with a brush body. However, the end of the brush body close to the first end is also difficult to directly reach the blind corner due to the obstruction of the mounting portion. In order to ensure the stability of the brush body assembly connection, the end of the brush body away from the first end needs to be indirectly connected to the base. Therefore, this floor scrubber is also unable to completely clean blind corners.

[0088] In view of this, the second embodiment of the present application proposes a cleaning mechanism 20, which has a good cleaning effect on blind spots of cleaning objects. The cleaning mechanism 20 can be used for cleaning equipment. It should be noted that the cleaning mechanism 20 can be used to clean floors, walls, or glass surfaces, etc. The embodiment of the present application uses the cleaning mechanism 20 for cleaning floors as an example. The cleaning mechanism 20 of the embodiment of the application is described below with reference to Figures 1 to 7. Specifically, the cleaning mechanism 20 includes a base 200, a drive assembly 300, and a brush assembly 400.

[0089] Referring to Figures 13 to 16 , the base 200 can be used to mount the drive assembly 300, the brush assembly 400, and the like. The specific configuration of the base 200 can be referenced in related known art. The base 200 includes a mounting portion 210, which is used to connect to the drive assembly 300. The mounting portion 210 has a first side surface 211 and a second side surface 212 that face away from each other. It is understood that the mounting portion 210 can extend away from the base 200.

[0090] The drive assembly 300 can provide driving force, that is, it can drive the brush body assembly 400 to move, thereby achieving effective cleaning of foreign matter. Referring to Figure 14, the drive assembly 300 is connected to the mounting portion 210. The drive assembly 300 includes a first drive portion 310 and a second drive portion 320. The arrangement of the first drive portion 310 can be the same as or different from that of the second drive portion 320. It can be understood that in some embodiments, the first drive portion 310 and the second drive portion 320 can be arranged as one body. In other embodiments, the first drive portion 310 and the second drive portion 320 can be arranged separately. Some embodiments of the present application are described by taking the integrated arrangement of the first drive portion 310 and the second drive portion 320 as an example.

[0091] 14 and 17 , the first driving portion 310 is connected to the first side surface 211 of the mounting portion 210 , and the second driving portion 320 is connected to the second side surface 212 of the mounting portion 210 , that is, the mounting portion 210 is located between the first driving portion 310 and the second driving portion 320 .

[0092] The brush assembly 400 can directly clean the surface of an object. Referring to Figures 1 and 2 , the brush assembly 400 includes a first brush body 410 connected to the first driving unit 310 and a second brush body 420 connected to the second driving unit 320 .

[0093] The specific movement process of the first driving unit 310 driving the first brush body 410 is described below. Referring to Figure 14, in some embodiments, the first driving unit 310 has a first central axis 311, and the first central axis 311 can extend in the horizontal direction. The first driving unit 310 can drive the first brush body 410 to rotate around the first central axis 311 to achieve efficient cleaning of foreign matter. It can be understood that the first brush body 410 can rotate in a clockwise direction or in a counterclockwise direction. In other embodiments, the first driving unit 310 can also drive the first brush body 410 to reciprocate horizontally to clean foreign matter. Some embodiments of the present application are described by taking the first driving unit 310 driving the first brush body 410 to rotate as an example.

[0094] The following describes the specific movement process of the second driving unit 320 driving the second brush body 420. Referring to Figure 14, in some embodiments, the second driving unit 320 has a second central axis 321, which can extend horizontally. The second driving unit 320 can drive the second brush body 420 to rotate about the second central axis 321 to achieve efficient cleaning of foreign matter. The rotation direction of the second brush body 420 can be the same as or different from that of the first brush body 410. In other embodiments, the second driving unit 320 can also drive the second brush body 420 to reciprocate horizontally to clean foreign matter. Some embodiments of the present application are described using the example of the second driving unit 320 driving the second brush body 420 to rotate.

[0095] It should be noted that in some embodiments, the first central axis 311 and the second central axis 321 may be collinear, i.e., the first drive unit 310 and the second drive unit 320 rotate coaxially. In other embodiments, the first central axis 311 and the second central axis 321 may not be collinear. This may depend on the actual situation. In some embodiments of the present application, the first central axis 311 and the second central axis 321 are collinear as an example.

[0096] It should be noted that in some embodiments, the first drive unit 310 can directly drive the first brush body 410, and the second drive unit 320 can directly drive the second brush body 420. In other embodiments, a main drive unit can be added to drive the first drive unit 310 and the second drive unit 320, thereby indirectly driving the first brush body 410 and the second brush body 420. Some embodiments of this application are described using the latter indirect drive as an example.

[0097] In the technical solution of this application, the mounting portion 210 of the base 200 includes a first side surface 211 and a second side surface 212 arranged opposite each other. The first driving portion 310 of the driving assembly 300 is connected to the first side surface 211, and the second driving portion 320 is connected to the second side surface 212. The first brush body 410 of the brush assembly 400 is connected to the first driving portion 310, and the second brush body 420 is connected to the second driving portion 320. In other words, the mounting portion 210 is disposed between the first brush body 410 and the second brush body 420. In the prior art, the brush body of a floor scrubber is hindered from directly reaching blind spots due to the obstruction of the mounting portion. Therefore, it cannot directly clean blind spots in the object being cleaned, resulting in poor cleaning results. In this embodiment, the first brush body 410 and the second brush body 420 are respectively provided on either side of the mounting portion 210. This means that the ends of the first brush body 410 and the second brush body 420 facing away from the mounting portion 210 are not obstructed by the mounting portion 210. Therefore, they can directly reach even the most challenging corners of the cleaning object, significantly improving the edge cleaning capability of the cleaning mechanism 20 and ensuring effective cleaning of even the most challenging corners. Furthermore, because the first brush body 410 and the second brush body 420 are independently arranged in this embodiment, individual brush bodies can be replaced, extending the overall cleaning time of the cleaning mechanism 20.

[0098] With reference to Figures 13, 14, and 17, the specific configuration of the drive assembly 300 is described below. In some embodiments, the drive assembly 300 includes a first drive motor 330, which can provide power to the brush assembly 400. Specifically, the first drive motor 330 has an output shaft 231. One end of the output shaft 231 extends toward the first side 211 and serves as the drive shaft of the first drive unit 310. In other words, one end of the output shaft 231 can drive the first brush 410. The other end of the output shaft 231 extends toward the second side 212 and serves as the drive shaft of the second drive unit 320. In other words, the other end of the output shaft 231 can drive the second brush 420. It will be appreciated that the extension length of the output shaft 231 toward the first side 211 and the extension length toward the second side 212 can be equal or different, depending on the actual situation. In this solution, the driving shaft of the first driving part 310 and the driving shaft of the second driving part 320 are arranged integrally, which can ensure the synchronization of driving the first brush body 410 and the second brush body 420 and improve the driving stability.

[0099] In other embodiments, the drive assembly 300 includes a second drive motor and a third drive motor. The second drive motor has an output shaft 231. The output shaft 231 of the second drive motor extends toward the first side 211 and serves as the drive shaft of the first drive unit 310. The output shaft 231 of the third drive motor extends toward the second side 212 and serves as the drive shaft of the second drive unit 320. The extension length of the output shaft 231 of the second drive motor and the extension length of the output shaft 231 of the third drive motor can be different or equal. In this solution, the drive shaft of the first drive unit 310 and the drive shaft of the second drive unit 320 are arranged separately, so that drive shafts with different drive strengths can be arranged for the first drive unit 310 and the second drive unit 320 to adapt to different drive requirements, and when the first drive unit 310 or the second drive unit 320 fails, they can also be replaced or repaired separately, thereby extending the service life of the cleaning mechanism 20 as a whole.

[0100] The specific arrangement of the first brush body 410 is described below. In some embodiments, the first brush body 410 includes a first cleaning member and a first barrel 411. It is understandable that the first cleaning member can be a fiber fabric or a colloid material, etc., which is not shown in the accompanying drawings. The first barrel 411 can support the first cleaning member to ensure the cleaning effect of the object to be cleaned. The first cleaning member is installed on the surface of the first barrel 411. Specifically, in some embodiments, the first cleaning member can be sleeved on the outer peripheral surface of the first barrel 411. In other embodiments, the first cleaning member can also be directly bonded to the outer peripheral surface of the first barrel 411, etc. The specific arrangement may depend on the actual situation. Some embodiments of the present application are described by taking the first cleaning member sleeved on the first barrel 411 as an example.

[0101] The following describes the connection between the first brush body 410 and the first drive unit 310. Specifically, the first barrel 411 in the first brush body 410 is mounted on the first drive unit 310. In some embodiments, the first barrel 411 can be sleeved around the first drive unit 310. In other embodiments, the first barrel 411 can also be snapped onto the first drive unit 310. Some embodiments of this application are described using the example of the first barrel 411 sleeved around the first drive unit 310.

[0102] The following describes the specific arrangement of the second brush body 420. In some embodiments, the second brush body 420 includes a second cleaning member and a second cylindrical body 421. The second cleaning member can have the same configuration as the first cleaning member. The second cleaning member can be mounted on the outer circumference of the second cylindrical body 421. The second cylindrical body 421 can have the same configuration as the first cylindrical body 411, and can house a second driving unit.

[0103] The following describes the specific configuration of the first extension portion of the first brush body 410. The first brush body 410 includes a first cleaning member and a first barrel 411. At at least one end of the first barrel 411, the first cleaning member extends outward from the end of the first barrel 411 to form a first extension portion. It is understood that in some embodiments, a single first extension portion may be provided, and the single first extension portion may be provided at the end of the first barrel 411 facing away from the second barrel 421 along its extension direction. This allows the first extension portion of the first brush body 410 to directly contact blind spots in the object being cleaned, ensuring effective cleaning. In other embodiments, a single first extension portion may be provided, and the single first extension portion may be provided at the end of the first barrel 411 facing the second barrel 421 along its extension direction. A gap exists between the end of the first barrel 411 facing the second barrel 421 and the end of the second barrel 421 facing the first barrel 411. The extended first extension portion may cover this gap, and it should be noted that the first extension portion may partially or completely cover this gap. Since the mounting portion 210 is arranged in this interval, the area passed by the mounting portion 210 can be directly cleaned by the first extension portion of the first brush body 410, that is, the cleaning mechanism 20 of this solution does not need to adjust the cleaning position a second time to clean the area that the mounting portion 210 cannot directly clean, which can effectively improve the cleaning efficiency and ensure the cleaning effect.

[0104] The following describes the specific configuration of the second extension portion of the second brush body 420. The second brush body 420 includes a second cleaning member and a second barrel 421. At at least one end of the second barrel 421, the second cleaning member extends outward from the end of the second barrel 421 to form a second extension portion. It should be noted that in some embodiments, a single second extension portion can be provided. This single second extension portion can be located at the end of the second barrel 421 facing away from the first barrel 411 along its extension direction. This allows the second extension portion of the second brush body 420 to directly contact blind spots in the object being cleaned, ensuring effective cleaning. In other embodiments, a single second extension portion can be provided. This single second extension portion can be located at the end of the second barrel 421 facing the first barrel 411 along its extension direction. A gap exists between the end of the first barrel 411 facing the second barrel 421 and the end of the second barrel 421 facing the first barrel 411. The extended second extension portion can cover this gap, and it should be noted that the second extension portion can partially or completely cover this gap. Since the mounting portion 210 is arranged in this interval, the area passed by the mounting portion 210 can be directly cleaned by the second extension portion of the second brush body 420, that is, the cleaning mechanism 20 of this solution does not need to adjust the cleaning position a second time to clean the area that the mounting portion 210 cannot directly clean, which can effectively improve the cleaning efficiency and ensure the cleaning effect.

[0105] It should be noted that in some embodiments, the first extension portion and the second extension portion may be arranged simultaneously, wherein the first extension portion and the second extension portion may jointly cover the gap between the first barrel 411 and the second barrel 421.
