[0042] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be apparent to one skilled in the art that the present application can be practiced without the specific details set forth in this description. In other instances, well-known methods, procedures, components, and circuits have not been described in detail as not to unnecessarily obscure aspects of the present application.

[0043] The present application provides a cleaning device and an elastic column. The structure and working principle of the cleaning device and the elastic column of the present application are described below by using specific embodiments. It should be noted that the embodiments described below are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of the present application. In order to facilitate the understanding of the cleaning device of the present application, the structure of the floor brush installed on the cleaning device is first described in detail.

[0044] First Embodiment

[0045] The first embodiment of the present application provides a cleaning device. The cleaning device in the present application can be a handheld cleaning device, can be an automatic floor cleaning machine, and of course can be other cleaning devices equipped with a floor brush. In a specific working scenario, the floor brush installed on the cleaning device is mainly used to clean the pollutants attached to the working surface to be cleaned.

[0046] Specifically, the reason why the floor brush can clean the pollutants attached to the working surface to be cleaned is that the floor brush of the existing cleaning device comprises a roller brush assembly. The roller brush assembly is generally installed on the floor brush base by magnetic attraction. More specifically, a magnet is arranged on the floor brush base, and an iron sheet is arranged on the roller brush handle. The roller brush handle is directly connected with the roller brush body to form a roller brush assembly. Thus, the roller brush handle can be attracted to the floor brush base by magnetic attraction, so that the roller brush assembly is naturally arranged on the floor brush base. After the roller brush body is arranged on the floor brush base, it can clean the pollutants attached to the working surface to be cleaned. However, the roller brush assembly installed by magnetic attraction is prone to falling off the floor brush base during use of the cleaning device. For example, during cleaning, if the floor brush is hit by a large force, the roller brush assembly is easily detached from the floor brush base, thereby causing poor user experience. Meanwhile, the magnetic attraction method for installing the roller brush assembly has a high cost.

[0047] In order to solve the above-mentioned problems of the existing cleaning device during cleaning, the present application provides a cleaning device. The cleaning device comprises a floor brush, and the floor brush comprises a roller brush assembly, a floor brush base and a deformable component. In the specific structure of installing the roller brush assembly on the floor brush base, the deformable component can be arranged on the roller brush assembly or the floor brush base. When the deformable component is arranged on the roller brush assembly, a first matching structure can be arranged on the deformable component, and a second matching structure can be arranged on the floor brush base. Of course, the deformable component can also be arranged on the floor brush base. When the deformable component is arranged on the floor brush base, a first matching structure can be arranged on the deformable component, and a second matching structure can be arranged on the roller brush assembly. Regardless of the above-mentioned arrangement of the deformable component, the deformable component can be deformed when subjected to an acting force, so that the first matching structure and the second matching structure are mutually embedded, thereby arranging the roller brush assembly on the floor brush base, or the deformable component can be deformed when subjected to an acting force, so that the first matching structure and the second matching structure are mutually separated, thereby dismounting the roller brush assembly from the floor brush base.

[0048] Specifically, the above-mentioned roller brush assembly comprises a roller brush body and a lifting component. When the deformable component is arranged on the roller brush assembly, the deformable component is actually arranged on the lifting component. Similarly, when the second matching structure is arranged on the roller brush assembly, the second matching structure is actually arranged on the lifting component.

[0049] In order to facilitate understanding of the above-mentioned floor brush structure, please refer to Figure 1 which is a first structure diagram of the floor brush in the cleaning device provided by the first embodiment. The floor brush of the present embodiment comprises a floor brush base 101, a lifting component 102 and a roller brush body 103.

[0050] In the present embodiment, when the roller brush assembly is placed on the floor brush base 101, one end (A end) of the roller brush body 103 is connected with one end (A1 end) of the pull member 102. At the same time, the other end (B end) of the roller brush body 103 is connected with the floor brush base 101. At the part of the floor brush base 101 where the other end (B end) of the roller brush body 103 is connected, a structure that matches the structure of the other end (B end) of the roller brush body 103 and can accommodate the other end (B end) of the roller brush body 103 is arranged.

[0051] It should be noted that the one end (A end) of the roller brush body 103 and the one end (A1 end) of the pull member 102 are connected in a detachable manner. In this way, when the roller brush body is damaged or needs to be removed, the roller brush body can be easily removed from the pull member 102.

[0052] Please continue to refer to Figure 1 , the B1 end of the pull member 102 is provided with a groove structure 102-2, which includes an annular side wall and a side plate connected with the annular side wall. Correspondingly, a boss structure 101-2 that matches the size of the groove structure 102-2 is arranged on the floor brush base 101. The A1 end of the pull member 102 is the end without the groove structure, and the B1 end is the end with the groove structure. The A end of the roller brush body 103 is the first end of the roller brush body, and the B end of the roller brush body 103 is the second end of the roller brush body.

[0053] Specifically, the groove structure 102-2 actually includes a wall surface that forms a groove. The shape and size of the boss structure 101-2 match the groove formed by the groove structure 102-2. When the roller brush assembly is assembled with the floor brush base, the groove structure 102-2 is sleeved on the outer contour of the boss structure 101-2. In this embodiment, the boss structure 101-2 can actually be regarded as a deformable member. In this way, the deformable member is arranged on the floor brush base 101, and the boss structure 101-2 is regarded as a first matching structure, and the groove structure 102-2 is regarded as a second matching structure.

[0054] In order to further make the groove structure 102-2 more firmly sleeved on the outer contour of the boss structure 101-2 when the roller brush assembly is assembled on the floor brush base 101, please continue to refer to Figure 1The first hole structure 102-1 can be a through hole structure, or a non-through groove formed on the inner wall surface of the groove structure 102-2. The first hole structure 102-1 actually serves as the second matching structure; correspondingly, the first protrusion 101-1 on the boss structure 101-2 serves as the first matching structure. The positions of the first hole structure 102-1 on the groove structure 102-2 and the first protrusion 101-1 on the boss structure 101-2 are such that when the groove structure 102-2 is sleeved on the outer contour of the boss structure 101-2, the first protrusion 101-1 is arranged in the first hole structure 102-1, realizing the arrangement of the roller brush assembly on the floor brush base 101. In this way, the first protrusion 101-1 can be used as a deformable component.

[0055] Of course Figure 1 The above is only an example of the illustration. When the boss structure 101-2 is used as a deformable component, the boss structure 101-2 can also be arranged on the B1 end of the pulling component 102; correspondingly, the groove structure 102-2 is arranged on the floor brush base 101, and the positions of the boss structure 101-2 on the B1 end of the pulling component 102 and the groove structure 102-2 on the floor brush base 101 are such that when the groove structure 102-2 is sleeved on the outer contour of the boss structure 101-2, the roller brush assembly can be exactly assembled on the floor brush base 101. Similarly, when the first protrusion 101-1 is used as a deformable component, the boss structure 101-2 can also be arranged on the B1 end of the pulling component 102, and the first protrusion 101-1 is arranged on the boss structure 101-2; correspondingly, the groove structure 102-2 is arranged on the floor brush base 101, and the first hole structure 102-1 is arranged on the wall surface of the groove structure 102-2, and the positions of the boss structure 101-2 on the B1 end of the pulling component 102, the first protrusion 101-1 on the boss structure 101-2, and the groove structure 102-2 on the floor brush base 101, and the first hole structure 102-1 on the groove structure 102-2 are such that when the groove structure 102-2 is sleeved on the outer contour of the boss structure 101-2, the first protrusion 101-1 is arranged in the first hole structure 102-1, and the roller brush assembly can be exactly assembled on the floor brush base 101.

[0056] In summary, no matter which way is adopted, the size of the first protrusion 101-1 and the first hole structure 102-1 is matched with each other, the size of the boss structure 101-2 and the groove structure 102-2 is also matched with each other, and the position of the first protrusion 101-1 on the boss structure 101-2 and the position of the first hole structure 102-1 on the groove structure 102-2 are such that when the groove structure 102-2 is sleeved on the outer contour of the boss structure 101-2, the first protrusion 101-1 is arranged in the first hole structure 102-1, and thus the roll brush assembly can be exactly assembled on the floor brush base 101.

[0057] The reason why the boss structure and the groove structure are respectively arranged on the floor brush base or the lifting component, and the first protrusion is further arranged on the boss structure and the first hole structure is arranged on the groove structure in the technical solution of the present application is to make full use of the advantages of the shapes of the components in the cleaning device, and then assemble the components together. The protrusion and the groove or hole structure can well combine the floor brush base and the roll brush assembly, so that the roll brush assembly is also relatively firm on the floor brush base. In the following description of the specific combination of the floor brush base and the roll brush assembly, the way of installing different styles of protrusion structures on the floor brush base can be adopted.

[0058] The above Figure 1 An example of the floor brush provided for installation on the cleaning device is provided, in which a boss structure is directly arranged on the floor brush base or a first protrusion is arranged on the boss structure. In the present application, other components can also be arranged on the floor brush base, and the roll brush assembly can be assembled on the floor brush base 101 by arranging protrusions on the other components and buckling the protrusions with the hole structure on the groove structure.

[0059] First, the first way of arranging other components on the floor brush base is introduced. Specifically, please refer to Figure 2 And Figure 3 which are the second and third structural schematic diagrams of the floor brush in the cleaning device provided by the first embodiment. The second and third schematic diagrams are schematic diagrams of the roll brush assembly not arranged on the floor brush base and the roll brush assembly arranged on the floor brush base, respectively.

[0060] Please refer to Figure 2The elastic sheet 104 has a second protrusion 104-1. It is to be noted that the second protrusion 104-1 has the same function as the first protrusion 101-1. Therefore, the protrusion on the base of the floor brush can be either the first protrusion or the second protrusion, i.e. the first protrusion can be the first matching structure or the second protrusion can be the first matching structure. The elastic sheet 104 is elastic and can be a deformable component, which can keep elastic when placed on the base of the floor brush. When the second protrusion 104-1 is provided on the elastic sheet 104, the second hole structure 102-3 is provided on the groove structure 102-2 as the second matching structure. When the roller brush assembly is installed on the base of the floor brush, the second protrusion 104-1 is placed in the second hole structure 102-3.

[0061] Specifically, at least a part of the elastic sheet 104 can be placed on the base of the floor brush 101 by the screw 105. The elastic sheet 104 can be placed on the base of the floor brush 101 by the screw 105 because the elastic sheet 104 and the base of the floor brush 101 have screw holes 106 matching the size of the screw 105. The elastic sheet 104 is placed on the base of the floor brush 101 by embedding the screw 105 in the screw hole 106.

[0062] Please refer to Figure 3 Because the elastic sheet 104 has the second protrusion 104-1, the roller brush assembly can be placed on the base of the floor brush when the second protrusion 104-1 is placed in the second hole structure 102-3 of the pulling component 102. Of course, it can be understood that the size of the second hole structure 102-3 in this example matches the size of the second protrusion 104-1. The connection between the two ends of the pulling component 102, the two ends of the roller brush body and the base of the floor brush can be understood by referring to the description of the example of the base of the floor brush having the first protrusion, which will not be repeated here. By Figure 3 It can be seen that the second hole structure 102-3 is a non-through groove. Of course, the second hole structure 102-3 can also be a through hole structure.

[0063] By Figure 3 It can be seen that the elastic sheet 104 has a second protrusion 104-1 on each of the upper and lower ends of the open side, so that at least two second protrusions 104-1 are provided on the elastic sheet 104, which can more firmly place the roller brush assembly on the base of the floor brush.

[0064] It should be noted that the second protrusion 104-1 on the elastic sheet 104 also needs to penetrate the boss structure 101-2 when being arranged in the second hole structure 102-3, and therefore, a through hole structure (not shown in the figure) needs to be arranged on the boss structure 101-2 to ensure that the second protrusion 104-1 passes through the through hole structure on the boss structure 101-2 and is then arranged in the second hole structure 102-3. Of course, it can be understood that the size of the through hole structure on the boss structure 101-2 matches the size of the second protrusion 104-1, so that the second protrusion 104-1 can pass through the through hole structure and be arranged in the second hole structure 102-3.

[0065] Specifically, since the second hole structure 102-3 is a groove structure, in order to disengage the second protrusion 104-1 from the second hole structure 102-3 when disassembling the roller brush assembly on the brush base, the deformation amount of the second protrusion 104-1 needs to be such that the second protrusion 104-1 can be disengaged from the through hole structure on the boss structure 101-2, and the elastic sheet 104 needs to be fixed by the screw 105.

[0066] The above combination Figure 2 With Figure 3 The first way of arranging other components on the brush base is introduced below. Figures 4 to 7 The second way of arranging other components on the brush base is introduced below.

[0067] The second way of arranging other components on the brush base can be as follows: Specifically, please refer to Figure 4 , which is a fourth structure diagram of a brush in a cleaning device provided by the first embodiment, and the fourth diagram is a diagram of the brush not being arranged on the brush base.

[0068] In this way, an elastic column 107 (the elastic column 107 can be used as a deformable component) is arranged on the brush base 101, and the elastic column 107 has a third protrusion 107-1 as a first matching structure. It should be noted that in this embodiment, the third protrusion 107-1 is different from the first protrusion 101-1 in the above Figure 1 or the second protrusion 104-1 in the above Figure 2The function of the second protrusion 104-1 in the second embodiment is the same as that of the first protrusion 104-1 in the first embodiment. Therefore, one of the three protrusions arranged on the floor brush base can be selected. The elastic column 107 is elastic and can maintain elasticity when arranged on the floor brush base 101. When the third protrusion 107-1 is arranged on the elastic column 107, a third hole structure 102-4 as a second matching structure is arranged on the groove structure 102-2 correspondingly. When the roller brush assembly is mounted on the floor brush base, the third protrusion 107-1 is arranged in the third hole structure 102-4. It should be noted that in this embodiment, the second hole structure 102-3 or the third hole structure 102-4 is arranged on the groove structure 102-2, and the second hole structure 102-3 or the third hole structure 102-4 can also be arranged at other positions of the roller brush assembly.

[0069] In order to facilitate understanding of how the roller brush assembly is arranged on the floor brush base, please refer to Figure 5 which is a fifth structure diagram of the floor brush in the cleaning device provided by the first embodiment, and the fifth diagram is a diagram of the roller brush assembly arranged on the floor brush base. Since the elastic column 107 has the third protrusion 107-1, the roller brush assembly can be arranged on the floor brush base when the third protrusion 107-1 is arranged in the third hole structure 102-4 on the pull member 102. Of course, it can be understood that the size of the third hole structure 102-4 in this example is matched with the size of the third protrusion 107-1. For the connection mode between the two ends of the pull member 102, the two ends of the roller brush body and the floor brush base, please refer to the related description of the example of arranging the first protrusion on the floor brush base, which will not be repeated here. Through Figure 5 It can be seen that the third hole structure 102-4 is a through hole structure. Of course, the third hole structure 102-4 can also be arranged as a groove.

[0070] It should be noted that the third protrusion 107-1 on the elastic column 107 needs to penetrate the boss structure 101-2 when arranged in the third hole structure 102-4, and therefore a through hole structure 108 Figure 4 shown in the second embodiment) needs to be arranged on the boss structure 101-2 to ensure that the third protrusion 107-1 passes through the through hole structure 108 on the boss structure 101-2 and is arranged in the third hole structure 102-4. Of course, it can be understood that the size of the through hole structure 108 is matched with the size of the third protrusion 107-1, so that the third protrusion 107-1 can pass through the through hole structure 108 and be arranged in the third hole structure 102-4.

[0071] Specifically, part of the elastic column 107 can be arranged as Figure 4 or Figure 5The elastic column 107 has a U-shaped structure, and the elastic column 107 includes two cantilever arms, one end of the two cantilever arms is a fulcrum O, and the two cantilever arms are symmetrical about the fulcrum O; the other end of the two cantilever arms respectively forms a free end (C end and D end), and the third protrusion 107-1 is arranged at the free end.

[0072] In order to better understand the structure of the elastic column 107, two structures of the elastic column are provided in the embodiment. Specifically, please refer to Figure 6 and Figure 7 which are respectively a schematic diagram of the first structure of the first elastic column and a schematic diagram of the first structure of the second elastic column of the first embodiment.

[0073] The structure of the first elastic column is shown in Figure 6 It can be seen from Figure 6 that the elastic column 107 has one third protrusion 107-1 arranged at each of the upper and lower ends of the open side. In this way, the arrangement of at least two third protrusions 107-1 can more firmly place the roller brush assembly on the floor brush base.

[0074] In the structure of the elastic column 107, the direction from the fulcrum (O point) at the intersection of the two cantilever arms of the elastic column 107 to the free end is not a regular circular arc shape. For example, the column part of the AOB segment is not a regular circular arc shape in the side view direction, and the straight line segment is at the fulcrum (O point). And from the fulcrum to the free end of the elastic column, the width of the elastic column 107 is at least partially the same. For example, the width of the elastic column 107 is the same in the direction from the O point to the A point or in the direction from the O point to the B point; or the width of the elastic column 107 is the same in the direction from the O point to the C point or in the direction from the O point to the D point.

[0075] The structure of the second elastic column is shown in Figures 7 to 9 , Figure 7 The upper part is a side view and the lower part is a top view. Figure 8 is a schematic diagram of the second structure of the second elastic column of the first embodiment, which represents a perspective view of the second elastic column.

[0076] It can be seen from Figure 7 that the elastic column 107 has one third protrusion 107-1 arranged at each of the upper and lower ends of the open side. At the same time, please refer to Figure 7 It can also be seen that the fourth protrusion 107-2 is arranged at each of the upper and lower ends of the free end of the elastic column, and the fourth protrusion 107-2 is used to limit the floor brush base when the elastic column is installed on the floor brush base. When the roller brush assembly is installed on the floor brush base, the fourth protrusion 107-2 does not pass through the through hole structure 108.

[0077] Please continue to refer to Figure 7In the structure of the elastic column 107, in the direction extending from the fulcrum (point O) to the free end, a portion of the column body adopts an arc shape in the side view direction. For example, the column body portion of segment AOB is arc-shaped in the side view direction. The portion of the elastic column 107 with an opening (i.e., the free end) connected to the arc shape is straight in the side view direction. That is, each cantilever of the elastic column 107 includes a straight segment and an arc segment (preferably an arc segment, which can be an elliptical arc segment). The two cantilevers meet at the fulcrum (point O) at the arc segment, and the two cantilevers form a free end at the end of the straight segment. At the same time, in the direction extending from the fulcrum (point O) to the free end (point C or point D) of the elastic column 107, the width of the elastic column 107 increases sequentially. Figure 7 As can be seen from the side view, the column corresponding to segment AOB is an arc segment in the side view direction, the column corresponding to AC and the column corresponding to BD are straight line segments in the side view direction, and the distance between CD is greater than the distance between AB. The angle between the straight line segments AC and BD and the horizontal line is between 5° and 20°, and from point O to point C (or point D), the angle between the tangent and the horizontal line at each point gradually decreases.

[0078] In the above Figure 7 In the illustrated structure, the distance between CD is greater than the distance between AB. That is, from the fulcrum to the free end, the distance between the two cantilever arms of the elastic column gradually increases, and the distance between the two free ends is the largest, i.e., the distance between CD is the largest. This structure allows the force acting on the two free ends to be relatively small enough to bring the two free ends closer together, causing the elastic column to deform, while ensuring that the elastic column 107 has a certain strength.

[0079] The reason for designing the columns corresponding to AC and BD as straight segments in the side view, and the column corresponding to AOB as an arc segment in the side view, thus creating an angled design for the entire elastic column as a straight segment, is primarily because the columns corresponding to OAC and OBD need to abut against the floor brush base. In this application, the columns corresponding to AC and BD actually abut against the floor brush base, that is, the floor brush base abuts against the upper and lower sections of the elastic column. When the floor brush base abuts against the upper and lower sections of the elastic column, due to the interaction force between the upper and lower ends of the floor brush base and the elastic column, the elastic column will be subjected to pressure from the floor brush base, which also facilitates the subsequent application of external force to deform the free end of the elastic column.

[0080] The structure also makes the force acting on the two free ends not need to be very large, so as to make the two free ends close to each other, so that the elastic column is deformed, and at the same time, the elastic column 107 has a certain strength.

[0081] The second structure of the elastic column is actually an optimized structure based on the first structure of the elastic column. By setting the width of the column part from the free end (C point or D point) of the elastic column 107 to the fulcrum (O point) of the elastic column 107 to be smaller in turn, and setting the corresponding column of the AOB section to be a circular arc in the side view direction, the third protrusion 107-1 on the elastic column 107 can be easily placed in the third hole structure 102-4, or the third protrusion 107-1 on the elastic column 107 can be easily removed from the third hole structure 102-4.

[0082] In the embodiment, the size of the third protrusion 107-1 is related to the size of the force required to be applied (the force can make the third protrusion deform). The height of the third protrusion 107-1 is generally 2-5 mm. In an example, the height of the third protrusion 107-1 can be 2.78 mm as indicated in Figure 9 At the same time, when the elastic column is not installed on the brush base, the size of the free end (including the height of the third protrusion) is 18.26 mm, Figure 9 is a schematic view of the third structure of the second elastic column. When the elastic column is installed on the brush base, the size of the free end (including the height of the third protrusion) is 17.8 mm. That is, when the elastic column is installed on the brush base, the free end of the elastic column is compressed.

[0083] Please refer to Figure 10Fig. 6 is a sixth structural schematic view of the ground brush in the cleaning device provided by the first embodiment of the present application. In order to facilitate holding the pulling component 102, or facilitate the user to exert force or use a smaller force to deform the deformable component when installing or dismounting the roller brush assembly on / from the ground brush base, a protruding structure 109 for prompting the user to exert pressure can be arranged on the edge of the side wall of the pulling component 102 close to the groove structure 102-2 and far from the first hole structure 102-1 (or the second hole structure 102-3, or the third hole structure 102-4), more specifically, one protruding structure 109 can be arranged on the edge of each of the upper and lower symmetrical side walls of the pulling component 102. The protruding structure can be various protruding shapes for prompting the user to exert pressure, for example, a wave-shaped protruding structure. In the embodiment, the position of the protruding structure 109 on the edge of the side wall of the pulling component 102 is not in a straight line with the position of the first hole structure 102-1 (or the second hole structure 102-3, or the third hole structure 102-4) on the annular side wall, which is achieved by the principle of the lever. The protruding structure 109 can be arranged at a position on the edge of the side wall of the pulling component 102, and when the groove structure 102-2 is sleeved on the outer contour of the boss structure 101-2, the position of the protruding structure 109 on the edge of the side wall of the pulling component 102 corresponds to the position of the edge of the accommodating groove 110 on the ground brush base, so as to facilitate the user to deform the deformable component by exerting a smaller force. At the same time, the protruding structure 109 arranged at the position on the edge of the side wall of the pulling component 102 leaves a larger space for the user to exert an external force. The protruding structure 109 not only facilitates the user to exert force to avoid insufficient friction when the user exerts force, but also visually prompts the user. Figure 10 As can be seen, the protruding structure 109 is not on the groove structure 102-2. According to the principle of the lever, the protruding structure 109 can be arranged at a position on the edge of the side wall of the pulling component 102, and when the groove structure 102-2 is sleeved on the outer contour of the boss structure 101-2, the position of the protruding structure 109 on the edge of the side wall of the pulling component 102 corresponds to the position of the edge of the accommodating groove 110 on the ground brush base, so as to facilitate the user to deform the deformable component by exerting a smaller force. At the same time, the protruding structure 109 arranged at the position on the edge of the side wall of the pulling component 102 leaves a larger space for the user to exert an external force. The protruding structure 109 not only facilitates the user to exert force to avoid insufficient friction when the user exerts force, but also visually prompts the user.

[0084] Specifically, referring to Figure 1 With Figure 10 As can be seen, the boss structure 101-2 is actually arranged in the accommodating groove 110 on the ground brush base, and the size of the accommodating groove 110 is greater than the size of the groove structure 102-2. When the groove structure 102-2 is sleeved on the outer contour of the boss structure 101-2, the inner side wall of the accommodating groove 110 and the pulling component 102 form an annular gap, and the user can exert an external force through the annular gap, and then exert a pressing force on the pulling component 102 towards the ground brush base or an outward pulling force away from the ground brush base. Therefore, the protruding structure 109 described above can be arranged at a position on the edge of the side wall of the pulling component 102, so that a larger space is left for the user to exert an external force.

[0085] In fact, the protruding structure 109 can also be installed on the annular outer wall of the groove structure 102-2, or on the A1-end-to-B1-end straight segment of the pulling component 102, specifically, please refer to Figure 11 Fig. 7 is a seventh structure diagram of the ground brush in the cleaning device provided by the first embodiment of the present application. In Figure 11 In the illustrated structure, the protruding structure 109 can also be arranged on both sides of the A1-end-to-B1-end straight segment of the pulling component 102.

[0086] In actual use, when the user installs the roller brush assembly on the ground brush base, the roller brush body can be assembled with the pulling component first, then the user holds the pulling component, aligns the groove structure 102-2 with the boss structure 101-2, and then applies an external force, so that the third protrusion 107-1 on the elastic column 107 passes through the through-hole structure 108 on the boss structure 101-2, and is then installed in the third hole structure 102-4, thereby fixing the roller brush assembly on the ground brush base.

[0087] When the roller brush assembly is removed from the ground brush base, the hand can act on the protruding structure 109 on the pulling component, and pull outward from the outward direction of the side of the ground brush base, and the force is transmitted to the third protrusion 107-1, and the elastic column 107 is deformed. In this process, the free end of the elastic column actually deforms, so that the third protrusion 107-1 is separated from the third hole structure 102-4 of the pulling component, so as to remove the roller brush body together with the pulling component from the ground brush base.

[0088] Of course, the above installation of the roller brush assembly on the ground brush base, or the disassembly of the roller brush assembly from the ground brush base, is described by taking the elastic column as an example of a deformable component. Similarly, a spring or boss structure can also be used as an example of a deformable component to describe how to install the roller brush assembly on the ground brush base, or disassemble the roller brush assembly from the ground brush base.

[0089] The cleaning device provided in the application comprises a floor brush, the floor brush comprising a rolling brush assembly, a floor brush base and a deformable component; the deformable component is arranged on the floor brush base, the deformable component comprises a first matching structure, and the rolling brush assembly is provided with a second matching structure; or the deformable component is arranged on the rolling brush assembly, the deformable component comprises a first matching structure, and the floor brush base is provided with a second matching structure; the deformable component can be deformed when subjected to an acting force, so that the first matching structure and the second matching structure are embedded, the rolling brush assembly is arranged on the floor brush base is realized; or the deformable component can be deformed when subjected to an acting force, so that the first matching structure and the second matching structure are separated from the embedded state, the rolling brush assembly is detached from the floor brush base is realized, so that the rolling brush assembly is arranged on the floor brush base or detached from the floor brush base when the deformable component is subjected to an acting force. This structure avoids the rolling brush assembly from falling off the floor brush base during the cleaning process of the cleaning device, and the setting mode of this structure saves cost compared with the existing magnetic attraction structure.
