As used in the specification of the embodiments of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are intended to include the plural forms.

[0030] As Figures 1 - 6 shown, in a first aspect, the present invention provides a roller brush assembly, comprising: a fixed frame 1, a roller brush locking member 5, and a cleaning member assembly 18; the cleaning member assembly 18 is disposed inside the fixed frame 1; the cleaning member assembly 18 includes a housing 2 and a cleaning member 19 disposed inside the housing; an air duct opening 6 is provided on the outer side wall of the housing 2; the roller brush locking member 5 is disposed on the fixed frame 1 and is detachably embedded in the air duct opening 6; wherein, when the roller brush locking member 5 is disengaged from the air duct opening 6, the cleaning member assembly 18 can be withdrawn from the fixed frame 1; when the roller brush locking member 5 is embedded in the air duct opening 6, the cleaning member assembly 18 is fixed inside the fixed frame 1.

[0031] In a specific implementation, when using the roller brush assembly for cleaning work, the air duct opening 6 is used to connect the roller brush locking member 5 and the housing 2 in a snap-fit manner, so as to fix the housing 2 inside the fixed frame 1, thereby playing a role in fixing the cleaning member assembly 18 and preventing the cleaning member assembly 18 from shifting due to vibration; by disposing the cleaning member 19 inside the housing 2 of the cleaning member assembly 18, and at the same time disposing the roller brush locking member 5 on the fixed frame 1 and detachably embedding it in the air duct opening 6, when it is necessary to replace the cleaning member 19 in the roller brush assembly, only need to disengage the roller brush locking member 5 from the air duct opening 6, then the cleaning member assembly 18 can be withdrawn from the fixed frame 1, achieving the effect of conveniently and quickly replacing the cleaning member 19 after withdrawing the cleaning member assembly 18 without lifting the fixed frame 1.

[0032] It should be noted that in the following embodiments of the present invention, the cleaning member 19 may specifically be the roller 192 and the water scraping strip 191. Or, in some other embodiments, the cleaning member 19 may specifically be other similar cleaning devices. In this regard, the present invention does not make specific limitations, as long as it is a cleaning device that needs to be replaced.

[0033] Further, as Figures 1 - 6 shown, a slide rail 3 is provided on the inner side wall of the fixed frame 1, and a slider 4 cooperating with the slide rail 3 is provided on the outer side wall of the housing 2; the slide rail 3 is connected to the slider 4.

[0034] The slide rail 3 and the slider 4 are used to enable the housing 2 to slide on the slide rail 3 through the slider 4, so that the cleaning part assembly 18 slides out of the fixed frame 1, achieving the effect that the cleaning part 19 can be conveniently and quickly replaced after the cleaning part assembly 18 is taken out without lifting the fixed frame 1.

[0035] Further, as Figures 1 - 6 shown, the cleaning part 19 includes a rotary brush 192; the rotary brush 192 is connected to the housing 2, and the rotary brush 192 is rotatably arranged axially in the housing 2.

[0036] When the rotary brush 192 is arranged in the housing 2 and the rotary brush 192 needs to be replaced, the rotary brush locking part 5 embedded in the air duct opening 6 is pulled outwards until the rotary brush locking part 5 disengages from the air duct opening 6, so that the housing 2 can slide on the slide rail 3 through the slider 4 provided on the housing 2, so that the cleaning part assembly 18 moves out of the fixed frame 1, achieving the effect that the rotary brush 192 can be conveniently and quickly replaced after the cleaning part assembly 18 is taken out without lifting the fixed frame 1.

[0037] Further, as Figures 1 - 6 shown, the cleaning part 19 further includes a water scraping strip 191; the water scraping strip 191 is detachably arranged on the inner side wall of the housing 2.

[0038] When using the roller brush assembly for cleaning work, in addition to using the roller brush 192, a water squeegee 191 is often used to clean water stains. As a wearing part, the water squeegee 191 also has a replacement requirement. Therefore, the water squeegee 191 is also arranged in the housing 2. When the water squeegee 191 needs to be replaced, the roller brush locking member 5 in the air duct opening 6 is pulled outwards until the roller brush locking member 5 disengages from the air duct opening 6, so that the housing 2 can slide on the slide rail 3 through the slider 4 provided on the housing 2, thereby moving the cleaning part assembly 18 out of the fixed frame 1, achieving the effect of conveniently and quickly replacing the water squeegee 191 after the cleaning part assembly 18 is taken out without lifting the fixed frame 1. Therefore, by arranging both the roller brush 192 and the water squeegee 191 in the housing 2, when one or both of them need to be replaced, only the housing 2 needs to slide on the slide rail 3 through the slider 4 until the cleaning part assembly 18 is taken out from the fixed frame 1, and then the replacement operation can be carried out without lifting the fuselage, saving time and effort.

[0039] Further, as Figures 1 - 6 shown, the roller brush assembly further includes a spring fixing column 8 and a spring 7; the spring fixing column 8 is connected to the fixed frame 1; the spring 7 is sleeved on the spring fixing column 8; one side of the roller brush locking member 5 is sleeved on the spring fixing column 8 and connected to the spring 7, and is located between the spring 7 and the fixed frame 1.

[0040] In specific implementation, the spring fixing column 8 is used to fix the spring 7 on the spring fixing column 8 to perform telescopic movement; one side of the roller brush locking member 5 is located between the spring 7 and the fixed frame 1, and one side of the roller brush locking member 5 is connected to the spring 7. Therefore, when it is necessary to disengage the roller brush locking member 5 from the air duct opening 6, only the roller brush locking member 5 needs to be pushed outwards, so that by compressing the spring 7, one side of the roller brush locking member 5 changes from the state of contacting the fixed frame 1 to the state of being away from the fixed frame 1, thereby moving the roller brush locking member 5 outwards of the air duct opening 6 until it disengages from the air duct opening 6.

[0041] Further, as Figures 1 - 6 shown, the roller brush assembly further includes a first slide rail 10 and a first slider 9; the first slide rail 10 is connected to the fixed frame 1; the first slider 9 is arranged on the lower end surface of the roller brush locking member 5; the first slide rail 10 is connected to the first slider 9.

[0042] In specific implementation, the first slide rail 10 and the first slider 9 are used to make the roller brush locking member 5 perform linear reciprocating motion along a linear track.

[0043] Further, as Figures 1 - 6 shown, the rotary brush assembly further includes a rotary brush cover 15, a transmission rod group 16, and a push rod 13; the rotary brush cover 15 is movably connected to the transmission rod group 16, and the rotary brush cover 15 covers the right opening of the fixed frame 1; the transmission rod group 16 is connected to the push rod 13; wherein, when the rotary brush cover 15 is opened outward, it drives the transmission rod group 16 to rotate, and the transmission rod group 16 rotates to drive the push rod 13 to move linearly; the linear movement of the push rod 13 pushes the rotary brush locking member 5 so that the rotary brush locking member 5 disengages from the air duct opening 6.

[0044] In a specific implementation, when the cleaning member 19 needs to be replaced, the rotary brush cover 15 is opened outward, thereby driving the transmission rod group 16 to rotate, and the transmission rod group 16 rotates to drive the push rod 13 to move linearly towards the rotary brush locking member 5; the linear movement of the push rod 13 contacts and pushes the rotary brush locking member 5 so that the rotary brush locking member 5 disengages from the air duct opening 6, achieving unlocking of the cleaning member assembly 18. At this time, the housing 2 can slide on the slide rail 3 through the slider 4, so that the cleaning member assembly 18 moves out of the fixed frame 1, and then the cleaning member 19 can be replaced.

[0045] After the replacement of the cleaning member 19 is completed, the slider 4 slides on the slide rail 3 into the fixed frame 1, thereby driving the housing 2 to retract into the fixed frame 1, so that the cleaning member assembly 18 retracts to the fixed position within the fixed frame 1. At this time, the rotary brush cover 15 is closed, and the closing movement of the rotary brush cover 15 drives the transmission rod group 16 to rotate, and the transmission rod group 16 rotates to drive the push rod 13 to move linearly away from the rotary brush locking member 5 until the push rod 13 disengages from the contact with the rotary brush locking member 5; during the process of the push rod 13 disengaging from the contact with the rotary brush locking member 5, one side of the rotary brush locking member 5 changes from a state away from the fixed frame 1 to a state of contacting the fixed frame 1 (i.e., making the spring return to its shape before compression), and the rotary brush locking member 5 moves into the air duct opening 6 until it is connected to the air duct opening 6, thereby achieving locking of the cleaning member assembly 18, and at this time, the cleaning member assembly 18 can be fixed.

[0046] Further, as Figures 1 - 6 shown, the rotary brush assembly further includes a second slide rail 11, a second slider 12, and a second slide rail fixing member 14; the second slide rail fixing member 14 is disposed above the transmission rod group 16, and the second slide rail fixing member 14 is connected to the transmission rod group 16; the second slide rail fixing member 14 is connected to the second slide rail 11; the second slider 12 is disposed on the upper end surface of the push rod 13, and the second slider 12 is connected to the second slide rail 11.

[0047] In specific implementation, the second slide rail fixing member 14 is used to fix the second slide rail 11; the second slide rail 11 and the second slider 12 are used to make the push rod 13 perform a linear reciprocating motion.

[0048] In specific implementation, as Figures 1 - 6 shown, the housing 2 is a columnar structure with an opening on one side, and the opening of the housing 2 faces the bottom surface of the fixed frame 1. The columnar housing 2 facilitates the internal placement of the cleaning member 19. In other embodiments, according to actual situations and requirements, the housing 2 can be of other forms of structures, and the present invention does not make specific limitations.

[0049] Furthermore, as Figures 1 - 6 shown, the roller brush assembly further includes a driving device 17; the driving device 17 is arranged outside the fixed frame 1; the driving device 17 is connected to the roller brush 192.

[0050] In specific implementation, the driving device 17 is used to drive the roller brush 192 to rotate. The driving device 17 can be a driving motor or other driving devices, and the present invention does not make specific limitations.
