Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, specifically to a cleaning device, a floor brush, and a method for assembling the same. Background Technology

[0002] Floor scrubbers and cleaning machines with functions such as washing and mopping can perform cleaning tasks on behalf of users, bringing them great convenience and thus gaining widespread use. The floor brushes of floor scrubbers are typically equipped with a gearbox assembly and a roller brush; the gearbox assembly drives the roller brush to rotate and clean the floor.

[0003] The gearbox assembly is typically located at the end of the roller brush along its axial direction, meaning it's situated in the side space of the floor brush. This gearbox assembly occupies too much side space of the floor brush, and the brush housing structure also occupies considerable side space, limiting the axial length of the roller brush. This prevents the roller brush from achieving the function of cleaning both sides and corners, resulting in poor cleaning performance and low cleaning efficiency for current floor scrubbers.

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to up, down, left, and right in the actual use or working state of the device, specifically the drawing directions in the accompanying drawings.

[0042] In this application, unless otherwise expressly specified and limited, the terms "connected," "linked," "stacked," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] This application provides a cleaning device, a floor brush, and an assembly method thereof, which are described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0044] Please see Figure 1 , Figure 1 This is a partial schematic diagram of the cross-sectional structure of a ground brush in the prior art.

[0045] In the prior art, the floor brush of a floor scrubber includes a brush cover 31 and a brush base 32. The brush cover 31 and the brush base 32 are mated to form a space for accommodating a gearbox assembly 33 and a roller brush 34. The gearbox assembly 33 is inserted into the brush base 32 from top to bottom, and then the brush cover 31 is placed on top of the brush base 32, and the brush cover 31 and the brush base 32 are locked together by screws in the vertical direction to fix the gearbox assembly 33. The gearbox assembly 33 is located at the axial end of the roller brush 34, that is, the gearbox assembly 33 is located in the side space of the brush. The brush base 32 is injection molded with a side wall member 35, which serves as the outer side wall of the entire brush. Due to the presence of the side wall member 35 and the assembly gap between it and the gearbox assembly 33, the thickness of the entire side space of the brush (e.g., ...) is increased. Figure 1As shown in D1, where D1 reaches 31.3mm, the length of the roller brush 34 on this side is relatively large, which limits the length of the roller brush 34 on this side. As a result, the roller brush 34 cannot reach a reasonable cleaning size on this side and cannot achieve the function of cleaning both sides of the corners. This means that the cleaning effect of the current floor scrubber is poor and the cleaning efficiency is low.

[0046] In view of this, the present application provides a cleaning device, a floor brush and an assembly method thereof, which can solve the technical problem in the prior art that the limited length of the roller brush leads to poor cleaning effect and low cleaning efficiency of the floor scrubber, which will be described in detail below.

[0047] Please see Figure 2 and Figure 3 , Figure 2 This is a structural schematic diagram of one embodiment of the present application. Figure 3 This is an exploded structural diagram of one embodiment of the present application.

[0048] In one embodiment, the cleaning device can be a floor scrubber or other cleaning equipment. The cleaning device includes a main unit and a floor brush 10 connected to the main unit. The floor brush 10 is used to clean the surface 20 to be cleaned, which can be a floor or similar surface. The floor brush 10, also called a cleaning head or suction head, typically has a built-in roller brush for cleaning the surface 20. The user holds the main unit to move the floor brush 10 across the surface 20, allowing the floor brush 10 to clean the area it passes through. Of course, in other embodiments of this application, the cleaning device can also be a cleaning robot, which can move autonomously across the surface 20, allowing the floor brush 10 on the robot to clean the area it passes through. The following description uses a floor scrubber as an example only for illustrative purposes and does not limit the type of cleaning device in the embodiments of this application. For example, the cleaning device can also be an upright vacuum cleaner, a handheld vacuum cleaner, or a floor cleaning robot.

[0049] The floor brush 10 includes a housing assembly 11. The housing assembly 11 serves as the basic carrier of the floor brush 10, and it supports and protects the other components of the floor brush 10. Specifically, the housing assembly 11 includes a cover housing 116 and a base housing 117. The cover housing 116 is located on the side of the base housing 117 opposite to the surface 20 to be cleaned, and the cover housing 116 and the base housing 117 are mated to form a space for accommodating at least some of the components of the floor brush 10.

[0050] The floor brush 10 also includes a roller brush assembly 12. The roller brush assembly 12 is disposed on the housing assembly 11 and is used to clean the surface 20 to be cleaned. Specifically, the roller brush assembly 12 includes a roller brush 123, which rotates about its own central axis to clean the surface 20 to be cleaned.

[0051] The floor brush 10 also includes a drive assembly 13. The drive assembly 13 is disposed on the housing assembly 11 and is pulverizedly connected to the roller brush assembly 12. The drive assembly 13 is used to drive the roller brush assembly 12 to clean the surface 20 to be cleaned. Specifically, the drive assembly 13 is pulverizedly connected to the roller brush 123 and is used to drive the roller brush 123 to rotate to clean the surface 20 to be cleaned.

[0052] Please refer to the following: Figures 4 to 7 , Figure 4 This is a structural schematic diagram of one embodiment of the base housing of this application. Figure 5 yes Figure 4 The diagram shows a partial structural diagram of region A of the base housing. Figure 6 This is a structural schematic diagram of one embodiment of the base housing, drive assembly, and decorative parts of this application. Figure 7 yes Figure 6 The diagram shows a partial structural schematic of the base housing, drive assembly, and decorative part B area.

[0053] In one embodiment, the floor brush 10 is defined with mutually perpendicular first directions (e.g., Figure 1 (As indicated by the middle arrow X, the same below) and the second direction (as shown by the middle arrow X) and the second direction ( Figure 1 (As indicated by the middle arrow Y, the same applies below). Both the first and second directions are parallel to the surface 20 to be cleaned. For example, if the surface 20 to be cleaned is a horizontal plane, the floor brush 10 can move along the first direction on the surface 20 to be cleaned. The central axis of the roller brush 123 of the roller brush assembly 12 is parallel to the second direction.

[0054] The housing assembly 11 has a first target end face 112 and a mounting groove 111 on one side in the second direction. The first target end face 112 is located at the end of the housing assembly 11 in the second direction, that is, the first target end face 112 is the outer wall surface of the housing assembly 11 in the second direction. A portion of the first target end face 112 is located in the cover housing 116 of the housing assembly 11, and the remaining portion is located in the base housing 117. Figure 5 The first target end face 112 on the base housing 117 is shown. The inner wall of the mounting groove 111 is adjacent to the first target end face 112. In other words, in this embodiment, the mounting groove 111 extends through the housing assembly 11 in the second direction, so that the outer edge of the inner wall of the mounting groove 111 can meet the edge of the first target end face 112. That is, in this embodiment, the housing assembly 11 eliminates the side wall member 35 of the floor brush base 32 in the prior art.

[0055] The drive assembly 13 is located inside the housing assembly 11, specifically within the space formed by the mating of the cover housing 116 and the base housing 117. The drive assembly 13 is positioned adjacent to the end of the roller brush assembly 12 near the first target end face 112. At least a portion of the drive assembly 13 is located within the mounting groove 111. In this way, this embodiment allows the drive assembly 13 to be as close as possible to the first target end face 112 of the housing assembly 11, providing sufficient space for the roller brush assembly 12 in the second direction. This facilitates increasing the length of the roller brush assembly 12 in the second direction, thereby improving the cleaning effect and efficiency of the floor brush 10.

[0056] In this embodiment, the housing assembly 11 eliminates the side wall component 35 of the floor brush base 32 in the prior art, thus eliminating the space occupied by the side wall component 35 and the assembly gap between it and the drive assembly 13 in the second direction. This embodiment optimizes the structure of the housing assembly 11 and the arrangement of components such as the drive assembly 13 to increase the length of the roller brush assembly 12 in the second direction, so that the roller brush assembly 12 reaches the maximum cleaning size in the second direction, realizing the edge cleaning function of the roller brush assembly 12, which is beneficial to improve the cleaning effect and cleaning efficiency of the floor brush 10.

[0057] Specifically, please refer to the following: Figure 8 The drive assembly 13 includes a drive element 131, a transmission mechanism 132, and a linkage mechanism 133. The drive element 131 is connected to the linkage mechanism 133 via the transmission mechanism 132, and the drive element 131 and the linkage mechanism 133 are located on the same side of the transmission mechanism 132. The drive element 131 can be a power element such as a motor. The linkage mechanism 133 is connected to the roller brush assembly 12, and the drive element 131 drives the linkage mechanism 133 via the transmission mechanism 132, thereby driving the roller brush 123 of the roller brush assembly 12 to rotate via the linkage mechanism 133.

[0058] The housing assembly 11 also has a mounting cavity 113 and a roller brush cavity 114 inside. The mounting cavity 113 and the roller brush cavity 114 are arranged sequentially along a first direction, and the mounting groove 111 and the mounting cavity 113 are arranged sequentially along a second direction. The roller brush assembly 12 is housed in the roller brush cavity 114. The driving member 131 is housed in the mounting cavity 113. The linkage mechanism 133 is housed in the roller brush cavity 114. The transmission mechanism 132 is housed in the mounting groove 111, and the transmission mechanism 132 is arranged close to the first target end face 112, so that the entire driving assembly 13 is arranged as close as possible to the first target end face 112, which helps to increase the length of the roller brush assembly 12 in the second direction, thereby improving the cleaning effect and cleaning efficiency of the floor brush 10.

[0059] In one embodiment, the housing assembly 11 further includes a partition 115 extending along a first direction. The partition 115 is located between the mounting groove 111 and the mounting cavity 113 to separate the mounting groove 111 and the mounting cavity 113. A transmission mechanism 132 is fixed to the partition 115, meaning that in this embodiment, the position of the drive assembly 13 in the second direction is fixed by the transmission mechanism 132. Furthermore, the partition 115 and the roller brush assembly 12 are spaced apart from each other along the first direction, meaning that in this embodiment, the partition 115 does not restrict the length of the roller brush assembly 12 in the second direction, while also serving to fix the drive assembly 13.

[0060] In one embodiment, when the mounting groove 111 penetrates the housing assembly 11 along the second direction, the slot 1111 of the mounting groove 111 adjacent to the first target end face 112 is a through opening. In this embodiment, the drive assembly 13 is installed into the interior of the housing assembly 11 along the second direction. Specifically, the drive assembly 13 passes through the slot 1111 along the second direction and is installed into the interior of the housing assembly 11, and the transmission mechanism 132 of the drive assembly 13 is assembled in the mounting groove 111.

[0061] It should be noted that in the prior art, the gearbox assembly 33 is installed into the brush base 32 from top to bottom, and then the brush cover 31 is placed on the brush base 32, and the brush cover 31 and the brush base 32 are locked together by screws in the vertical direction to fix the gearbox assembly 33. In contrast, in this embodiment, the housing assembly 11 is provided with a mounting groove 111, which extends through the housing assembly 11 in a second direction, allowing the drive assembly 13 to be installed into the housing assembly 11 in the second direction. Specifically, the brush 10 also defines a third direction perpendicular to the surface to be cleaned 20 (e.g., ...). Figure 2 (As indicated by the middle arrow Z, the same applies below). The drive assembly 13 is installed into the base housing 117 along the second direction, and the transmission mechanism 132 is fixed to the partition 115 to fix the position of the drive assembly 13 in the second direction. Then, the cover housing 116 is placed on the base housing 117 and fixed to the base housing 117 to fix the position of the drive assembly 13 in the third direction. In addition, the housing assembly 11 also restricts the position of the drive assembly 13 in the first direction, thus achieving reliable fixation of the drive assembly 13.

[0062] Furthermore, the floor brush 10 also includes a first fastener 141, such as... Figure 7 As shown. After the drive assembly 13 is installed into the housing assembly 11 along the second direction, the first fixing member 141 fixes the transmission mechanism 132 to the partition 115 along the second direction. For example, the number of first fixing members 141 can be one or more. Figure 7An exemplary example is shown where the number of first fasteners 141 is three. The first fasteners 141 can be fasteners such as screws or bolts, and the first fasteners 141 are spaced apart from each other to reliably fix the transmission mechanism 132 to the partition 115.

[0063] Furthermore, the partition 115 is provided with mounting holes 1151, such as... Figure 5 As shown. The mounting groove 111 and the mounting cavity 113 are connected to each other through the mounting hole 1151. The mounting hole 1151 extends along the second direction and is used to fix the transmission mechanism 132. During the process of the drive assembly 13 being installed into the housing assembly 11 along the second direction, the drive member 131 passes through the mounting groove 111 and the mounting hole 1151 in sequence along the second direction and is installed into the mounting cavity 113, while the transmission mechanism 132 is installed into the mounting groove 111 along the second direction.

[0064] In this embodiment, the partition 115 is provided with mounting holes 1151 to accommodate the assembly method in which the drive assembly 13 is inserted into the housing assembly 11 along the second direction. Furthermore, compared to the situation where the partition 115 lacks mounting holes 1151, requiring the drive assembly 13 to span across the partition 115, in this embodiment, the connection between the drive member 131 and the transmission mechanism 132 is embedded in the mounting holes 1151. This not only avoids the overall height of the floor brush 10 becoming excessive due to the drive assembly 13 spanning across the partition 115, but also ensures that the partition 115 provides sufficient space to arrange the first fixing member 141, thereby reliably fixing the transmission mechanism 132 to the partition 115. Figure 7 In the case where there are three first fasteners 141, each first fastener 141 is distributed sequentially at intervals along the circumference of the mounting hole 1151.

[0065] Furthermore, please refer to the following: Figure 9 The floor brush 10 also includes a second fixing member 142 and a third fixing member 143. Both the second fixing member 142 and the third fixing member 143 are disposed adjacent to the drive assembly 13. The second fixing member 142 and the third fixing member 143 are spaced apart from each other along a first direction. The second fixing member 142 and the third fixing member 143 cooperate to fix the cover housing 116 and the base housing 117, such that the cover housing 116 and the base housing 117 cooperate to restrict the position of the drive assembly 13 in a third direction.

[0066] For example, both the second fixing member 142 and the third fixing member 143 can be fasteners such as screws and bolts. Since the base housing 117 and the roller brush assembly 12 are arranged sequentially in the first direction, the base housing 117 is not arranged on the side of the linkage mechanism 133 away from the drive member 131, so a fixing member cannot be set there. Therefore, in this embodiment, the second fixing member 142 is arranged in the first direction between the drive member 131 and the linkage mechanism 133 of the drive assembly 13, and the third fixing member 143 is arranged in the first direction on the side of the drive member 131 away from the linkage mechanism 133. The cover housing 116 and the base housing 117 cooperate to reliably limit the position of the drive assembly 13 in the third direction.

[0067] Please refer to the following: Figure 10 , Figure 10 yes Figure 2 A partial schematic diagram of the cross-sectional structure of the ground brush in the CC direction.

[0068] In one embodiment, one of the housing assembly 11 and the drive assembly 13 is provided with a limiting rib 151 and the other is provided with a limiting groove 152. The limiting rib 151 is embedded in the limiting groove 152 to limit the relative position between the housing assembly 11 and the drive assembly 13 in the second direction, thereby facilitating the subsequent fixing of the cover housing 116 and the base housing 117 of the housing assembly 11.

[0069] One of the cover housing 116 and the drive assembly 13 is provided with a limiting rib 151, and the other is provided with a limiting groove 152. Figure 8 and Figure 10 An exemplary illustration shows that the transmission mechanism 132 of the drive assembly 13 is provided with a limiting rib 151, and the cover housing 116 is provided with a limiting groove 152. After the drive assembly 13 is installed into the base housing 117 along the second direction, the transmission mechanism 132 is fixed to the partition 115 by the first fixing member 141. At this time, the drive assembly 13 and the base housing 117 are relatively fixed. Then, the cover housing 116 is placed on the base housing 117, and the limiting rib 151 is embedded in the limiting groove 152 to limit the position of the cover housing 116 in the second direction, which facilitates the subsequent installation of the second fixing member 142 and the third fixing member 143, thereby fixing the position of the drive assembly 13 in the third direction.

[0070] Please refer to the following: Figure 11 , Figure 11 This is a schematic diagram of the structure of an embodiment of the roller brush of this application.

[0071] In one embodiment, the roller brush assembly 12 has a receiving cavity 121 with one end open 1211, specifically, the roller brush 123 has a receiving cavity 121 inside. The roller brush assembly 12 has a second target end face 122 near the first target end face 112, specifically the end of the roller brush 123 near the first target end face 112 facing the outer surface of the first target end face 112. The open 1211 is adjacent to the second target end face 122, that is, the second target end face 122 is arranged around the outer periphery of the open 1211. At least a portion of the linkage mechanism 133 is received in the receiving cavity 121 through the open 1211, such as... Figure 2 As shown. Since the drive assembly 13 is located near the second target end face 122 of the roller brush assembly 12, this embodiment further facilitates increasing the length of the roller brush assembly 12 in the second direction by setting at least a portion of the linkage mechanism 133 to be accommodated in the accommodating cavity 121, thereby improving the cleaning effect and efficiency of the floor brush 10.

[0072] In one embodiment, the cleaning device includes a main unit and a floor brush 10, with the main unit connected to the floor brush 10. The floor brush 10 is used to clean a surface 20 to be cleaned. The floor brush 10 defines a first direction and a second direction, both parallel to the surface 20 to be cleaned. The floor brush 10 is movable along the first direction on the surface 20. The floor brush 10 includes a housing assembly 11, which has a mounting cavity 113 and a roller brush cavity 114, arranged sequentially along the first direction. The floor brush 10 also includes a roller brush assembly 12, which is housed within the roller brush cavity 114. The floor brush 10 further includes a drive assembly 13, which includes a drive member 131 and a transmission mechanism 132. The drive member 131 is housed within the mounting cavity 113 and is drively connected to the roller brush assembly 12 via the transmission mechanism 132. The housing assembly 11 has a mounting groove 111 on one side in the second direction, the mounting groove 111 extends through the housing assembly 11 in the second direction, and at least a portion of the transmission mechanism 132 is accommodated in the mounting groove 111.

[0073] Please refer to the following: Figure 12 , Figure 12 yes Figure 2 A partial schematic diagram of the cross-sectional structure of the ground brush in the DD direction is shown.

[0074] In one embodiment, the floor brush 10 is used to clean the surface 20 to be cleaned. The floor brush 10 defines a first direction and a second direction that are perpendicular to each other, both of which are parallel to the surface 20 to be cleaned. The floor brush 10 is movable on the surface 20 to be cleaned along the first direction. The floor brush 10 includes a housing assembly 11 and a roller brush assembly 12. The housing assembly 11 has a first target end face 112 in the second direction. The roller brush assembly 12 is disposed on the housing assembly 11, and the roller brush assembly 12 has a second target end face 122 close to the first target end face 112, the second target end face 122 being closer to the interior of the housing assembly 11 than the first target end face 112. The floor brush 10 is divided into target areas 16, which are located between the second target end face 122 and the first target end face 112. The target areas 16 are adjacent to the second target end face 122 and the first target end face 112 respectively. The length of the target areas 16 in the second direction (specifically, the sum of the length D2 of the part of the drive component 13 in the target areas 16 in the second direction and the length D3 of the decorative part 17 in the second direction) is 7.9 mm to 9.1 mm.

[0075] In the prior art, due to the assembly gap between the sidewall component 35 and the gearbox assembly 33, the thickness D1 of the entire side space of the floor brush reaches 31.3mm, which limits the length of the roller brush 34 on this side. As a result, the roller brush 34 cannot achieve a reasonable cleaning size on this side and cannot achieve the function of cleaning both sides and corners, resulting in poor cleaning effect and low cleaning efficiency of the current floor scrubber. In contrast, this embodiment, by setting the mounting groove 111 in the housing assembly 11, optimizing the assembly method of the drive assembly 13, and optimizing the structure of the drive assembly 13 itself, makes the length of the target area 16 of the floor brush 10 in the second direction only 7.9mm to 9.1mm. This is much smaller than the thickness D1 of the side space of the floor brush in the prior art. This means that the thickness of the side space of the floor brush 10 in this embodiment is reduced, which can provide sufficient space for the roller brush assembly 12 in the second direction to maximize the length of the roller brush assembly 12 in the second direction. This allows the roller brush assembly 12 to achieve the maximum cleaning size on the side where the first target end face 112 is located, thereby improving the cleaning effect and cleaning efficiency of the floor brush 10.

[0076] Specifically, at least a portion of the drive component 13 is located in the target region 16, and the length D2 of this at least portion in the second direction is 7.6 mm to 8.6 mm, such as 7.6 mm, 7.8 mm, 8.0 mm, 8.2 mm, 8.4 mm, 8.6 mm, etc. Figure 12As shown. Further, the transmission mechanism 132 of the drive assembly 13 is located in the target area 16. The minimum length of each position on the transmission mechanism 132 in the second direction is D2. In this embodiment, by optimizing the structure of the drive assembly 13 itself, the minimum length of each position on the transmission mechanism 132 in the second direction reaches D2, and the length of the transmission mechanism 132 in the second direction is reduced by about 14mm.

[0077] The floor brush 10 also includes a decorative element 17. At least a portion of the decorative element 17 is received in a mounting groove 111, and the decorative element 17 is located on the side of the drive assembly 13 facing the first target end face 112, such as... Figure 7 As shown. In this way, by using the decorative element 17 to shield the drive assembly 13, this embodiment helps to ensure that the floor brush 10 has a good product appearance. For example, the decorative element 17 can also be integrated into the cover housing 116 or into the roller brush cover.

[0078] A gap exists between the transmission mechanism 132 of the drive assembly 13 and the first target end face 112 in the second direction, and the decorative part 17 is fitted into this gap. After the decorative part 17 is fitted into the mounting groove 111, the surface of the decorative part 17 facing away from the transmission mechanism 132 is flush with the first target end face 112. In this way, the drive assembly 13 and the decorative part 17 in this embodiment provide ample space for the roller brush assembly 12 in the second direction to maximize the length of the roller brush assembly 12 in the second direction, thereby improving the cleaning effect and efficiency of the floor brush 10. Further, the length D3 of the decorative part 17 in the second direction is 0.3mm to 0.5mm, for example, 0.3mm, 0.35mm, 0.4mm, 0.45mm, 0.5mm, etc. Figure 12 As shown.

[0079] Please see Figure 13 , Figure 13 This is a flowchart illustrating an embodiment of the assembly method of the floor brush according to this application. The assembly method of the floor brush described in this embodiment is based on the floor brush 10 described in the above embodiment, and will not be repeated here.

[0080] S101: Provides housing assembly for floor brushes.

[0081] In this embodiment, a housing assembly 11 for the floor brush 10 is provided, which serves as the base carrier for subsequently assembled components. The housing assembly 11 has a mounting groove 111 and a first target end face 112 in a second direction, with the inner wall of the mounting groove 111 adjacent to the first target end face 112. Furthermore, the housing assembly 11 of the floor brush 10 includes a cover housing 116 and a base housing 117. The cover housing 116 is located on the side of the base housing 117 facing away from the surface 20 to be cleaned, and the cover housing 116 and the base housing 117 abut to form a space for accommodating the remaining components of the floor brush 10.

[0082] S102: The drive assembly of the floor brush is inserted into the interior of the housing assembly along the second direction, such that at least a portion of the drive assembly is located in the mounting slot.

[0083] In this embodiment, the drive assembly 13 of the floor brush 10 is installed into the interior of the housing assembly 11 along the second direction, such that at least a portion of the drive assembly 13 is located in the mounting groove 111. Specifically, the drive member 131 of the drive assembly 13 is accommodated in the mounting cavity 113, and at least a portion of the transmission mechanism 132 of the drive assembly 13 is accommodated in the mounting groove 111.

[0084] Specifically, the drive assembly 13 is installed into the base housing 117 along the second direction, the drive member 131 passes through the mounting groove 111 and the mounting hole 1151 in sequence along the second direction and is installed into the mounting cavity 113, the transmission mechanism 132 is installed into the mounting groove 111 along the second direction and the transmission mechanism 132 is fixed to the partition 115; then the cover housing 116 is placed on the base housing 117, and the limiting rib 151 on the transmission mechanism 132 is simultaneously embedded into the limiting groove 152 on the cover housing 116; then the second fixing member 142 and the third fixing member 143 fix the cover housing 116 and the base housing 117 along the third direction.

[0085] S103: Connect the drive assembly to the roller brush assembly of the floor brush.

[0086] In this embodiment, the drive assembly 13 is connected to the roller brush assembly 12 of the floor brush 10 via a transmission mechanism 132. Specifically, the drive assembly 131 is connected to the roller brush assembly 12 of the floor brush 10 via a transmission mechanism 132. Specifically, the linkage mechanism 133 of the drive assembly 13 is housed in the receiving cavity 121 through an opening 1211 on the roller brush assembly 12, and the linkage mechanism 133 is connected to the roller brush assembly 12 via a transmission mechanism to drive the roller brush assembly 12 to rotate. At least a portion of the linkage mechanism 133 is housed in the receiving cavity 121, which further increases the length of the roller brush assembly 12 in the second direction, thereby improving the cleaning effect and efficiency of the floor brush 10.

[0087] The technical solutions provided in the embodiments of this application will be described below in conjunction with specific application scenarios.

[0088] Application Scenario 1:

[0089] The cleaning device is a floor scrubber, and the floor brush 10 is specifically the floor brush part of the floor scrubber. The floor brush 10 is used to clean the floor. The user holds the main unit to move the floor brush on the ground, and the floor brush can clean the area it passes through.

[0090] The floor brush 10 has a first direction and a second direction that are perpendicular to each other. Both the first direction and the second direction are parallel to the ground. The floor brush 10 can move on the ground along the first direction. The floor brush 10 includes a housing assembly 11, which has a mounting cavity 113 and a roller brush cavity 114. The mounting cavity 113 and the roller brush cavity 114 are arranged sequentially along the first direction. The floor brush 10 also includes a roller brush assembly 12, which is housed in the roller brush cavity 114. The floor brush 10 also includes a drive assembly 13, which includes a drive member 131 and a transmission mechanism 132. The drive member 131 is housed in the mounting cavity 113 and is drively connected to the roller brush assembly 12 through the transmission mechanism 132. The housing assembly 11 has a first target end face 112 and a mounting groove 111 on one side in the second direction. The inner wall of the mounting groove 111 is adjacent to the first target end face 112, and at least a portion of the transmission mechanism 132 is housed in the mounting groove 111.

[0091] The mounting groove 111 extends through the housing assembly 11 in the second direction, allowing the outer edge of the inner wall of the mounting groove 111 to abut the edge of the first target end face 112. This eliminates the need for the sidewall component 35 of the existing floor brush base 32, thus saving the space occupied by the sidewall component 35 and its assembly gap with the drive assembly 13 in the second direction. By optimizing the structure of the housing assembly 11 and the arrangement of components such as the drive assembly 13, the length of the roller brush assembly 12 in the second direction can be increased, allowing the roller brush assembly 12 to reach its maximum cleaning size in the second direction. This enables the roller brush assembly 12 to perform double-sided corner cleaning, improving the cleaning effect and efficiency of the floor brush 10.

[0092] Application Scenario 2:

[0093] Floor brush 10 is used in floor scrubbers; specifically, it is the floor brush part of the scrubber. Floor brush 10 is used to clean the floor. The user holds the main unit to move the floor brush across the floor, and the brush cleans the area it passes over.

[0094] The floor brush 10 has a first direction and a second direction that are perpendicular to each other. Both the first direction and the second direction are parallel to the ground. The floor brush 10 can move on the ground along the first direction. The floor brush 10 includes a housing assembly 11, which has a mounting cavity 113 and a roller brush cavity 114. The mounting cavity 113 and the roller brush cavity 114 are arranged sequentially along the first direction. The floor brush 10 also includes a roller brush assembly 12, which is housed in the roller brush cavity 114. The floor brush 10 also includes a drive assembly 13, which includes a drive member 131 and a transmission mechanism 132. The drive member 131 is housed in the mounting cavity 113 and is drively connected to the roller brush assembly 12 through the transmission mechanism 132. The housing assembly 11 has a first target end face 112 and a mounting groove 111 on one side in the second direction. The inner wall of the mounting groove 111 is adjacent to the first target end face 112, and at least a portion of the transmission mechanism 132 is housed in the mounting groove 111.

[0095] The mounting groove 111 extends through the housing assembly 11 in the second direction, allowing the outer edge of the inner wall of the mounting groove 111 to abut the edge of the first target end face 112. This eliminates the need for the sidewall component 35 of the existing floor brush base 32, thus saving the space occupied by the sidewall component 35 and its assembly gap with the drive assembly 13 in the second direction. By optimizing the structure of the housing assembly 11 and the arrangement of components such as the drive assembly 13, the length of the roller brush assembly 12 in the second direction can be increased, allowing the roller brush assembly 12 to reach its maximum cleaning size in the second direction. This enables the roller brush assembly 12 to perform double-sided corner cleaning, improving the cleaning effect and efficiency of the floor brush 10.

[0096] Application Scenario 3:

[0097] Floor brush 10 is used in floor scrubbers; specifically, it is the floor brush part of the scrubber. Floor brush 10 is used to clean the floor. The user holds the main unit to move the floor brush across the floor, and the brush cleans the area it passes over.

[0098] During the assembly of the floor brush 10, the drive assembly 13 is installed into the base housing 117 along the second direction, and the drive component 131 passes through the mounting groove 111 and the mounting hole 1151 in sequence along the second direction and is installed into the mounting cavity 113. The transmission mechanism 132 is installed into the mounting groove 111 along the second direction. Then, the transmission mechanism 132 is fixed to the partition 115 by three first fasteners 141 along the second direction. Then, the cover housing 116 is placed on the base housing 117, and the limiting rib 151 on the transmission mechanism 132 is simultaneously embedded into the limiting groove 152 on the cover housing 116. Then, the second fastener 142 and the third fastener 143 fix the cover housing 116 and the base housing 117 along the third direction.

[0099] Application Scenario 4:

[0100] Floor brush 10 is used in floor scrubbers; specifically, it is the floor brush part of the scrubber. Floor brush 10 is used to clean the floor. The user holds the main unit to move the floor brush across the floor, and the brush cleans the area it passes over.

[0101] The floor brush 10 defines a first direction and a second direction that are perpendicular to each other. Both the first direction and the second direction are parallel to the surface 20 to be cleaned. The floor brush 10 is capable of moving on the surface 20 to be cleaned along the first direction. The floor brush 10 includes a housing assembly 11 and a roller brush assembly 12. The housing assembly 11 has a first target end face 112 in the second direction. The roller brush assembly 12 is disposed on the housing assembly 11 and has a second target end face 122 close to the first target end face 112. The second target end face 122 is closer to the interior of the housing assembly 11 than the first target end face 112. The floor brush 10 divides a target area 16, which is located between the second target end face 122 and the first target end face 112, and the target area 16 is adjacent to both the second target end face 122 and the first target end face 112. The length of the target area 16 in the second direction is 7.9 mm to 9.1 mm.

[0102] In the prior art, due to the assembly gap between the sidewall component 35 and the gearbox assembly 33, the thickness D1 of the entire side space of the floor brush reaches 31.3mm, which limits the length of the roller brush 34 on this side. As a result, the roller brush 34 cannot achieve a reasonable cleaning size on this side and cannot achieve the function of cleaning both sides and corners, resulting in poor cleaning effect and low cleaning efficiency of the current floor scrubber. In contrast, this embodiment, by setting the mounting groove 111 in the housing assembly 11, optimizing the assembly method of the drive assembly 13, and optimizing the structure of the drive assembly 13 itself, makes the length of the target area 16 of the floor brush 10 in the second direction only 7.9mm to 9.1mm. This is much smaller than the thickness D1 of the side space of the floor brush in the prior art. This means that the thickness of the side space of the floor brush 10 in this embodiment is reduced, which can provide sufficient space for the roller brush assembly 12 in the second direction to maximize the length of the roller brush assembly 12 in the second direction. This allows the roller brush assembly 12 to achieve the maximum cleaning size on the side where the first target end face 112 is located, thereby improving the cleaning effect and cleaning efficiency of the floor brush 10.

The descriptions of the above embodiments are only for the purpose of helping to understand the methods and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
