However, these embodiments do not limit the present invention, and any modifications to the mechanism, method, or function made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0040] The terms used herein, such as "up," "down," "left," "right," "front," and "back," indicating spatial relative position, are for illustrative purposes to describe the relationship of one feature relative to another, as shown in the accompanying drawings. It is understood that, depending on the product's placement, these terms may be intended to include different orientations besides those shown in the figures, and should not be construed as limiting the claims. Furthermore, the descriptive term "horizontal" used herein is not entirely equivalent to being perpendicular to the direction of gravity, and allows for a certain angle of inclination.

[0041] One embodiment of this utility model provides a cleaning device, which can be a vacuum cleaner or a floor scrubber, etc. The cleaning device includes a floor brush assembly 100.

[0042] like Figure 1-5 As shown, the floor brush assembly 100 includes a housing 10 and a roller brush assembly. The housing 10 includes an air intake 31 and an air outlet 32, with a dust suction duct 33 formed between the air intake 31 and the air outlet 32. The roller brush assembly is located on the bottom side of the housing 10, and at least part of the dust suction duct 33 is located on the top side of the roller brush assembly.

[0043] When the floor brush assembly 100 cleans the floor, the roller brush assembly rotates at high speed, thereby drawing dirt from the floor into the suction duct 33 through the suction port 31. The cleaning device also includes a suction motor. When the floor brush assembly 100 cleans the floor, the suction motor operates, creating negative pressure within the suction duct 33. This allows dirt on the floor to be drawn upwards from the suction port 31 into the suction duct 33 on the top side of the roller brush, and then exits the suction duct 33 through the exhaust port 32. After exiting the suction duct 33, the dirt is collected in the dirt collection space of the cleaning device. When the floor brush assembly 100 is working, the flow direction of dirt within the floor brush assembly 100 is as follows: Figure 2 As shown by the arrow in the image.

[0044] In this embodiment, the housing 10 includes a housing body 11 and a cover plate 40. A top opening 12 is formed on the housing body 11 to expose the dust suction duct 33 at least partially on the top side of the housing 10. The top opening 12 is located between the air intake 31 and the air outlet 32.

[0045] The cover plate 40 is movably connected to the shell body 11 for opening or closing the top opening 12. When the cover plate 40 closes the top opening 12, it surrounds the shell body 11 to at least partially form the dust suction duct 33.

[0046] The user can open or close the top opening 12 by moving the cover plate 40. When the floor brush assembly 100 is working, the cover plate 40 closes the top opening 12, thus ensuring the airtightness of the suction duct 33 and allowing the floor brush assembly 100 to operate normally. If the suction duct 33 becomes blocked and needs to be addressed, the user can move the cover plate 40 to open the top opening 12 while the floor brush assembly 100 is stopped, and then use their fingers or other tools to clean the suction duct 33. After cleaning the suction duct 33, the user can then move the cover plate 40 to close the top opening 12.

[0047] The floor brush assembly 100 provided in this application embodiment is provided with a top opening 12 located on the top side of the suction duct 33 and a cover plate 40 for closing and opening the top opening 12. When the suction duct 33 is blocked or other issues need to be addressed, the user can move the cover plate 40 to open the top opening 12. In this way, when the suction duct 33 is blocked, the user can easily gather and clean the dirt in the suction duct 33, avoiding the problem of dirt blocking the suction duct 33 and affecting the normal operation of the floor brush assembly 100, improving the cleaning efficiency of the floor brush assembly 100 and enhancing the user experience.

[0048] The floor brush assembly 100 also includes a connecting tube 60, with at least a portion of the top opening 12 extending toward one end of the connecting tube 60, that is, at least a portion of the top opening 12 extends toward one end of the connecting tube 60 to be close to that end. When the connecting tube 60 needs cleaning, the user can clean the connecting tube 60 through the top opening 12.

[0049] In this embodiment, one end of the connecting pipe 60 is connected to the air outlet 32. At least a portion of the top opening 12 extends towards the end of the connecting pipe 60 that connects to the air outlet 32. When the floor brush assembly 100 is working, dirt in the suction duct 33 enters the connecting pipe 60 through the air outlet 32, and then enters the dirt collection space of the cleaning device through the connecting pipe 60. When blockage occurs inside the connecting pipe 60 near the air outlet 32 ​​and needs to be addressed, the user can open the top opening 12 and then use a finger or other tool to insert into the connecting pipe 60 through the top opening 12 to remove the dirt causing the blockage. Therefore, after the top opening 12 is opened, the user can not only clean the suction duct 33 but also the inside of the connecting pipe 60.

[0050] The floor brush assembly 100 also includes a first connecting structure 70, which allows one side of the cover plate 40 to be detachably connected to the housing body 11. When the cover plate 40 needs to close the top opening 12, the first connecting structure 70 can connect the cover plate 40 to the housing body 11, thereby preventing the cover plate 40 from moving relative to the housing body 11 and ensuring the sealing of the top opening 12. When the top opening 12 needs to be opened, the connection between the cover plate 40 and the housing body 11 can be released, thereby allowing the cover plate 40 to move relative to the housing body 11.

[0051] The first connecting structure 70 includes a latching groove 71 formed on the shell body 11, a latch 72 connected to the cover plate 40, and a driving structure 73 disposed on the cover plate 40 for driving the latch 72 to move relative to the cover plate 40. Under the drive of the driving structure 73, the latch 72 can move relative to the cover plate 40. When the cover plate 40 closes the top opening 12, the latch 72 is engaged in the latching groove 71, preventing the cover plate 40 from moving relative to the shell body 11, thus ensuring the sealing of the top opening 12. If the cover plate 40 needs to move to open the top opening 12, the driving structure 73 needs to drive the latch 72 to move, causing the latch 72 to disengage from the latching groove 71, after which the cover plate 40 can move.

[0052] The aforementioned drive structure 73 can be configured as a manual drive structure, meaning that the drive structure 73 can be manually operated to move the latch 72 relative to the cover plate 40, thereby allowing the latch 72 to disengage from the latch slot 71. This simplifies the opening method of the top opening 12 and improves the user experience of the floor brush assembly 100.

[0053] In this embodiment, two latches 72 are provided, arranged opposite to each other, and a return spring (not shown) is provided between the two latches 72 to keep them in the engaged position. Two latch slots 71 are also provided, arranged opposite to each other. The drive structure 73 is configured to drive the two latches 72 to move closer together against the elastic force of the return spring when subjected to external force. The two latches 72 move closer together away from the engaged position, thus disengaging from the two latch slots 71 respectively. When the drive structure 73 is no longer subjected to external force, the two latches 72 move away from each other under the elastic force of the return spring, returning to the engaged position, thus engaging into the two latch slots 71 respectively.

[0054] The floor brush assembly 100 also includes a second connecting structure 80, which is used to rotatably connect the other side of the cover plate 40 to the housing body 11, that is, the cover plate 40 can be opened and closed in a rotatable manner to open and close the top opening 12. This improves the convenience of opening and closing the top opening 12.

[0055] The second connection structure 80 includes a rotating shaft 81 formed on the cover plate 40 and a connecting part 82 formed on the shell body 11. The connecting part 82 is provided with a connecting hole 83 that matches the rotating shaft 81. The rotating shaft 81 is rotatably disposed in the connecting hole 83, so that the cover plate 40 can rotate relative to the shell body 11 to realize the opening and closing of the top opening 12.

[0056] The connecting part 82 is also provided with a slot 821. The slot 821 extends from the connecting hole 83 to the outer wall surface of the connecting part 82 along the radial direction of the connecting hole 83. The outer peripheral surface of the rotating shaft 81 includes a first plane 811 and a second plane 812 arranged in parallel. The distance between the first plane 811 and the second plane 812 is not greater than the width of the slot 821.

[0057] The distance between the first plane 811 and the second plane 812 is not greater than the width of the slot 821. This means that during the rotation of the shaft 81, if the relative direction of the first plane 811 and the second plane 812 is parallel to the width direction of the slot 821, the shaft 81 can enter the slot 821 through the connecting hole 83 and disengage from the connecting part 82. With the above configuration, when the cover plate 40 needs to be cleaned, the cover plate 40 is rotated to a suitable position, the shaft 81 can disengage from the connecting part 82, and the cover plate 40 can be removed from the shell body 11 for cleaning.

[0058] In one embodiment of the present invention, at least a portion of the cover plate 40 may be made transparent, so that the user can observe the condition inside the dust suction duct 33 through the cover plate 40, making it convenient to clean the dust suction duct 33 in a timely manner.

[0059] In this embodiment, the housing 10 includes a lower housing 111, an upper housing 112 located above the lower housing 111, and a lower cover 50 for the air duct disposed between the lower housing 111 and the upper housing 112.

[0060] The roller brush assembly includes a front roller brush 21 and a rear roller brush 22. When the floor brush assembly 100 cleans the floor, the front roller brush 21 and the rear roller brush 22, during their rotation, sweep dust, debris, and other dirt from the floor into the suction duct 33 through the suction port 31. The suction port 31 is located between the front roller brush 21 and the rear roller brush 22. When the floor brush assembly 100 cleans the floor, the scraped dirt is sucked into the suction duct 33 from between the front roller brush 21 and the rear roller brush 22.

[0061] The front roller brush 21 and the rear roller brush 22 are located below the lower cover of the air duct 50. The dust suction air duct 33 is partially formed between the lower cover of the air duct 50 and the upper housing 112, and the top opening 12 is formed in the upper housing 112.

[0062] In the existing floor brush assembly 100, the front roller brush 21 and the rear roller brush 22 are protected by the upper housing 112 and the housing 10. In this embodiment, the air duct lower cover 50 extends to the direction of the front roller brush 21 and above the rear roller brush 22. The front roller brush 21 and the rear roller brush 22 are protected by the air duct lower cover 50 and the lower housing 111, thereby simplifying the structure of the upper housing 112 and making the structure of the floor brush assembly 100 more reliable.

[0063] A connector 51 for communicating with the connecting pipe 60 is formed on the lower cover 50 of the air duct, and the air outlet 32 ​​is formed by the connector 51. The connector 51 is formed on the lower cover 50 of the air duct, and the connecting pipe 60 can better communicate with the dust suction air duct 33, making the structure of the floor brush assembly 100 more reliable and facilitating the assembly of the floor brush assembly 100.

[0064] The floor brush assembly 100 also includes a sealing ring 90 disposed at the top opening 12. When the cover plate 40 closes the top opening 12, the sealing ring 90 contacts the housing body 11 and the cover plate 40. When the cover plate 40 closes the top opening 12, the sealing ring 90 ensures that dirt in the suction duct 33 will not leak outward from the gap between the cover plate 40 and the housing body 11, so that the cover plate 40 can effectively close the top opening 12.
