Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 3, the present invention discloses a cleaning assembly 100, and the cleaning assembly 100 can be applied to a household cleaning device such as a sweeper, a scrubber, etc., so as to enhance the passing rate of large garbage and improve the cleaning effect of the household cleaning device such as the sweeper, the scrubber, etc.
The cleaning assembly 100 includes a cleaning module body 10, a roller assembly 20 assembled and fixed with the cleaning module body 10, and fixing assemblies installed at both ends of the roller assembly 20, wherein the fixing assemblies can drive the roller assembly 20 to move horizontally when cleaning the floor, so as to collect garbage with a large volume.
The cleaning module body 10 is provided with a receiving cavity 101 for receiving the roller assembly 20, and the receiving cavity 101 is opened toward the ground so as to assemble the roller assembly 20 into the receiving cavity 101 from bottom to top. The roller assembly 20 includes a first roller assembly 201 and a second roller assembly 202 arranged side by side, and in the traveling direction of the cleaning device, the first roller assembly 201 and the second roller assembly 202 are arranged in front and behind to clean the ground together. That is, the axis of the first roller assembly 201 is horizontally aligned with the axis of the second roller assembly 202.
Preferably, the structure of the first roller assembly 201 is identical to that of the second roller assembly 202 in this embodiment, so the following description will take the first roller assembly 201 as an example to describe the specific structure of the first roller assembly 201 and the second roller assembly 202 in detail; of course, the structure of the first roller assembly 201 and the second roller assembly 202 may be slightly different, and are not limited herein.
Referring to fig. 4, the first roller assembly 201 includes a roller 21, a roller brush 22 sleeved outside the roller 21, and a driving device (not shown) disposed inside the roller 21 for driving the roller 21 and the roller brush 22 to rotate synchronously, in general, the roller 21 is made of a rigid material that does not absorb water and is not easy to deform, and the roller brush 22 is sleeved on an outer cylindrical surface of the roller 21 and is made of a fabric fiber or sponge material that can absorb water and can be squeezed and deformed, so as to have a good absorption effect and a good cleaning effect when cleaning the ground. The driving device is built in the roller 21 and is used for providing the rotating torque of the roller 21 so that the roller 21 can rotate normally. Since the roller 21, the roller brush 22 and the driving device can be designed according to the prior art, they will not be described in detail here.
Referring to fig. 2, when the first roller assembly 201 and the second roller assembly 202 are arranged side by side, due to the presence of the roller brush 22, a squeezing distance a is formed between the first roller assembly 201 and the second roller assembly 202, and the squeezing distance a can meet the requirement of passing garbage of a conventional size. That is, the maximum trash passing capacity between the first roller assembly 201 and the second roller assembly 202 is generally a pressing distance a, which is generally a fixed value.
It should be noted that: 1. the "extrusion distance a" referred to herein may be a distance between inner wall surfaces of the two rolling brushes 22 of the first roller assembly 201 and the rolling brush 22 of the second roller assembly 202 before being deformed by extrusion, that is, a in fig. 2; the sum of the difference between the distances from the axis of the roller 21 to the outer wall surface after the two roller brushes 22 are completely deformed by squeezing (cannot be deformed further) and the outer wall surface before the squeezing deformation may be used. For example, if the distance between the outer wall surface before the extrusion deformation of one roller brush 22 and the axis of the roller 21 is 5 cm, the distance between the outer wall surface after the complete extrusion deformation and the axis of the roller 21 is 3 cm, the difference in distance is 2 cm, the distance between the outer wall surface before the extrusion deformation of the other roller brush 22 and the axis of the roller 21 is 5 cm, the distance between the outer wall surface after the extrusion deformation and the axis of the roller 21 is 3 cm, the difference in distance is 2 cm, and thus the extrusion distance a is 4 cm (2 cm +2 cm).
2. As used herein, "maximum waste passage capacity" essentially refers to the maximum size of waste that can pass between the first roller assembly 201 and the second roller assembly 202; when the size of the garbage is larger than the extrusion distance A, the garbage of the size can not pass through the existing roller assembly 20; in this regard, the present invention provides for improved waste throughput such that most size waste can be collected by the roller assembly 20.
Referring to fig. 1, fixing members are disposed at two ends of the roller assembly 20, and the fixing members are connected to the first roller assembly 201 and the second roller assembly 202, and the fixing members are configured to drive the first roller assembly 201 to move a first distance B in a direction away from the second roller assembly 202 along a horizontal direction, and also drive the second roller assembly 202 to move a second distance C in a direction away from the first roller assembly 201 along the horizontal direction, so that a maximum distance between the first roller assembly 201 and the second roller assembly 202 is = a squeezing distance a + the first distance B + the second distance C. In this way, the maximum garbage passing capacity between the first roller assembly 201 and the second roller assembly 202 is a + B + C, which significantly improves the maximum garbage passing capacity.
Of course, in other embodiments, the fixing component may also be used to drive only the first roller assembly 201 to move horizontally, or only the second roller assembly 202 to move horizontally, as long as the distance between the first roller assembly 201 and the second roller assembly 202 is greater than the squeezing distance a, so that most of the garbage can pass through, which is not limited herein.
The fixing components have two structures, namely a first fixing component 30 and a second fixing component 40, in this embodiment, one end of the roller component 20 is connected to the first fixing component 30 and assembled and fixed with the cleaning module main body 10 through the first fixing component 30, and the other end is connected to the second fixing component 40 and assembled and fixed with the cleaning module main body 10 through the second fixing component 40. Of course, as the second embodiment of the drum assembly 20 according to the present invention, it is also possible to connect both ends of the drum assembly 20 to the first fixing assemblies 30 and achieve the assembling fixation with the cleaning module main body 10, as long as the maximum garbage passing capacity can be improved by the first fixing assemblies 30. As the third embodiment of the drum assembly 20 according to the present invention, it is also possible to connect both ends of the drum assembly 20 to the second fixing assemblies 40 and to achieve assembly fixing with the cleaning module main body 10, as long as the maximum garbage passing capacity can be improved by the second fixing assemblies 40.
Referring to fig. 5 and 6 in combination with fig. 3, the first fixing assembly 30 includes a fixing outer cover 31, a fixing inner cover 32 assembled with the fixing outer cover 31, two fixing sliders 33, and a first elastic member 34 connected to the fixing sliders 33, preferably, the two fixing sliders 33 are disposed to be respectively connected to the ends of the first roller assembly 201 and the second roller assembly 202 in a positioning manner, the two fixing sliders 33 are both accommodated in an accommodating space formed by the combination of the fixing outer cover 31 and the fixing inner cover 32, and the two fixing sliders 33 are symmetrically disposed; the number of the first elastic members 34 is also two, and each first elastic member 34 is disposed between the corresponding fixed sliding block 33 and the fixed outer cover 31 to match with the corresponding fixed sliding block 33.
The fixed sliding block 33 includes a sliding portion 331 and a positioning portion 332 perpendicular to the sliding portion 331, a limiting rib 311 and a limiting groove 312 surrounded by the limiting rib 311 are disposed in the fixed outer cover 31, the sliding portion 331 is received in the limiting groove 312 in a limiting manner and can slide along the limiting groove 312, and a through groove 321 through which the positioning portion 332 penetrates and slides is disposed on the fixed inner cover 32. Preferably, the sliding portion 331 is rectangular, the limiting rib 311 in the fixed outer cover 31 is long, and the limiting groove 312 formed by surrounding the limiting rib 311 is rectangular, so that the sliding portion 331 is conveniently limited and contained in the limiting groove 312 and can only slide back and forth along the limiting groove 312. Of course, the fixing inner lid 32 may be provided with a limiting rib for cooperating with the limiting rib 311 of the fixing outer lid 31 to limit the sliding portion 331 of the fixing slider 33.
The positioning portion 332 is disposed in a circular shaft shape, and the through groove 321 is a long sliding groove, so that the positioning portion 332 can slide in the through groove 321, and then the position of the corresponding roller assembly is changed. In this embodiment, the positioning portion 332 on each fixed sliding block 33 is disposed near one side of the first elastic member 34 engaged therewith, so as to conveniently drive the corresponding roller assembly to move.
The first elastic element 34 is also accommodated in the limiting groove 312, and one end of the first elastic element is abutted against the sliding portion 331 of the fixed sliding block 33, and the other end of the first elastic element is abutted against the fixed outer cover 31, so that when the first roller assembly 201 and/or the second roller assembly 202 drives the corresponding fixed sliding block 33 to move horizontally, the first elastic element 34 is compressed, and after the pressure is released, the first elastic element 34 can reset the fixed sliding block 33. Preferably, the first elastic member 34 in this embodiment is a compression spring, but should not be limited thereto.

After the large garbage passes through, the first roller assembly 201 and the second roller assembly 202 are released, and at the same time, the first elastic member 34 elastically pushes the corresponding first roller assembly 201 and second roller assembly 202 to reset, so that the first roller assembly 201 and the second roller assembly 202 are pressed towards each other.
The fixing outer cover 31 is further internally provided with a buckling piece 313 and a pressure spring 314 abutted against the buckling piece 313, the fixing inner cover 32 is correspondingly provided with a buckling piece (not numbered) matched with the buckling piece 313, the top of the buckling piece 313 is provided with a buckling part 315, one end of the pressure spring 314 is abutted against the bottom of the buckling piece 313, the other end of the pressure spring 314 is abutted against the inner side wall of the fixing outer cover 31, and therefore when the buckling piece 313 is pressed, the pressure spring 314 can be compressed, the buckling part 315 moves downwards to be matched with the buckling piece, and the buckling connection of the fixing outer cover 31 and the fixing inner cover 32 is achieved.
The end portions of the first roller assembly 201 and the second roller assembly 202 are respectively provided with a supporting end cover 23, the supporting end cover 23 is internally provided with a positioning hole 231, and when the first fixing assembly 30 is assembled with the supporting end cover 23, the positioning portion 332 extends into the positioning hole 231 to be fixedly connected in a hole shaft positioning manner. Because the first fixing assembly 30 is provided with the two fixing sliders 33 arranged side by side, when the first fixing assembly 30 is assembled with the roller assembly 20, the positioning portions 332 of the two fixing sliders 33 can be directly inserted into the positioning holes 231 of the two supporting end covers 23, so that the positioning connection between the first fixing assembly 30 and the roller assembly 20 can be realized.
In the initial state, the distance between the two positioning portions 332 is equal to the distance between the axial center of the first roller assembly 201 and the axial center of the second roller assembly 202, and at this time, the extrusion distance between the first roller assembly 201 and the second roller assembly 202 is a.
Referring to fig. 3 and 4, the second fixing assembly 40 includes a rotating shaft pin 41 and a second elastic member 42, an end of the first roller assembly 201 and an end of the second roller assembly 202 are both slidably connected to a hole of the rotating shaft pin 41, and two ends of the second elastic member 42 are respectively fixedly connected to an end of the first roller assembly 201 and an end of the second roller assembly 202, so that the first roller assembly 201 and/or the second roller assembly 202 can horizontally slide along the rotating shaft pin 41, and the second elastic member 42 is stretched or released.
Specifically, both ends of the rotating shaft pin 41 are fixedly coupled to the hole shafts of the cleaning module body 10, respectively, so as to restrain the drum assembly 20 in the receiving chamber 101 below the cleaning module body 10.

In this embodiment, the first scraping strip 11 and the second scraping strip 12 are made of rubber material, so that the rolling brush 22 is not damaged when the dirt on the corresponding roller assembly is scraped.
The cleaning module main body 10 further includes a substantially closed space 13 formed between the first wiper strip 11, the second wiper strip 12, the first roller assembly 201, and the second roller assembly 202, an air duct 14 communicating with the closed space 13, a main suction port 15 for communicating the closed space 13 and the air duct 14, and a suction device (not shown) communicating with the air duct 14, the suction device being configured to generate a negative pressure so as to suck dirt scraped by the first wiper strip 11 and the second wiper strip 12 in the closed space 13 through the air duct 14.
Cleaning principle: the cleaning assembly 100 of the present invention adopts a double-roller brush cleaning scheme, the ground garbage is clamped by the clamping force between the double roller brushes and rotates upwards to bring the garbage from the bottom of the roller brush 22 to the upper part of the roller brush 22, at the moment, the rotating directions of the first roller assembly 201 and the second roller assembly 202 are opposite, the garbage and the sewage are scraped off by the first scraping strip 11 and the second scraping strip 12, the closed space 13 becomes a negative pressure cavity after air is extracted through the main suction opening 15, and the garbage and the sewage scraped off by the first scraping strip 11 and the second scraping strip 12 are sucked by the main suction opening 15 in the closed space 13 and then are conveyed to the garbage can through the air duct 14. When small garbage is cleaned, the small garbage mainly enters the closed space 13 through the extrusion space A between the first roller assembly 201 and the second roller assembly 202; when cleaning the large garbage, the large garbage enters the closed space 13 through the extrusion distance a between the first roller assembly 201 and the second roller assembly 202 + the first distance B at which the first roller assembly 201 moves forward + the second distance C at which the second roller assembly 202 moves backward, so that a larger garbage passing capacity is obtained.
In summary, the cleaning assembly 100 of the present invention has the fixing assemblies respectively disposed at the two ends of the roller assembly 20, so that the fixing assemblies can be used to drive the first roller assembly 201 to move the first distance B in the direction away from the second roller assembly 202, and the fixing assemblies can also be used to drive the second roller assembly 202 to move the second distance C in the direction away from the first roller assembly 201, so that the maximum distance between the first roller assembly 201 and the second roller assembly 202 = the squeezing distance a + the first distance B + the second distance C, thereby increasing the passing rate of the large garbage between the roller gaps.
Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
