In the preferred embodiment, the cleaning medium jet ports 32 face the surface of the roller brush, and at least some of the cleaning medium jet ports 32 are arranged in the axial direction of the roller brush 2, and the cleaning medium jet ports 32 arranged in the axial direction of the roller brush 2 have the same pitch. It is understood that the cleaning medium ejection openings 32 of the present embodiment are provided in a large number and based on the fact that the roll brush 2 is rotated about the axial direction, wherein at least a part of the cleaning medium ejection openings 32 is provided in the axial direction of the roll brush 2, it is possible to make the part of the cleaning medium ejection openings 32 cover a straight line of the roll brush surface in the axial direction, so that the part of the cleaning medium ejection openings 32 provided in the axial direction can cover the entire roll brush surface as the roll brush 2 is rotated. The purpose of setting the intervals between the cleaning medium ejection openings 32 to be equal distances is also to achieve uniform and continuous rolling brush surfaces covered by the respective cleaning medium ejection openings 32 on a straight line in the axial direction, thereby achieving uniform ejection of the cleaning medium to the entire rolling brush surface.

It should be noted that, in the present embodiment, the cleaning medium is uniformly sprayed on the entire surface of the roller brush, mainly based on the flow channel balance principle, as shown in the schematic diagram of the uniform flow channel path of the cleaning assembly 3 in fig. 3, the lengths of the flow channels from the cleaning medium injection ports 32 to the cleaning medium inlet 31, which are arranged along the axial direction of the roller brush 2, are the same, so that the amounts of the cleaning medium sprayed from the cleaning medium injection ports 32 are substantially the same, thereby uniformly spraying the cleaning medium on the entire surface of the roller brush, achieving the purpose of comprehensively cleaning the roller brush 2, and improving the cleaning effect.

In the present embodiment, as shown in fig. 3 in conjunction, in order to make the cleaning media ejected from the plurality of cleaning media ejection openings 32 uniform, the cleaning media ejection openings 32 are arranged in a multi-level structure, and as the levels increase, the number of cleaning media ejection openings 32 corresponding to the levels also increases, i.e., the levels of the cleaning media ejection openings 32 increase stepwise along the extending direction of the flow paths. In the present embodiment, the cleaning medium ejection openings 32 include, in order in the extending direction of the flow path, at least, a first-level cleaning medium ejection opening 321 and a second-level cleaning medium ejection opening 322; the first-level cleaning medium injection port 321 is connected with the cleaning medium inlet 31, the second-level cleaning medium injection port 322 is superposed with the first-level cleaning medium injection port 321 through the correspondingly connected flow channel branch, and the lengths of the flow channel branches between the first-level cleaning medium injection port and the second-level cleaning medium injection port are equal; and the number of cleaning medium ejection openings 32 of the corresponding level increases with increasing level; the number of the cleaning medium ejection openings 32 of the corresponding level is N times 2; where N is the level at which the cleaning medium ejection port 32 is located. For example, if N is equal to 1 for the first-stage cleaning-medium ejection openings 321 directly connected to the cleaning-medium inlet 31, the number of the first-stage cleaning-medium ejection openings 321 is 2; for another example, if the second-stage cleaning medium ejection openings 322 connected to the first-stage cleaning medium ejection openings 321 are N equal to 2, the number of the second-stage cleaning medium ejection openings 322 is 4.

That is, the longer the flow path extends, the more the stages are, and at the same time, the flow path of each stage is provided as a plurality of branches, and the flow path branch lengths of one stage are equal, so that the flow path lengths between the cleaning medium ejection openings 32 and the cleaning medium inlets 31 in each stage are equal, and the specifications of the flow paths are uniform, so that the cleaning media ejected from the plurality of cleaning medium ejection openings 32 are more uniform. It should be noted that, when the cleaning medium ejection openings 32 are arranged in a multi-stage structure, the cleaning medium ejection openings 32 of the respective stages are arranged in a stacked manner, that is, all the cleaning medium ejection openings 32 of one stage are arranged in a stacked manner as a whole and all the cleaning medium ejection openings 32 of the other stage are arranged in a stacked manner as a whole.

In the present embodiment, the cleaning medium ejection ports 32 arranged in a layered manner as a whole include two structures in which the purge assembly 3 is provided; as shown in fig. 1 and 5, the first cleaning module 3 is configured such that the flow path branches connected to the cleaning medium ejection openings 32 of the respective stages are located in the same plane, so that the cleaning medium ejection openings 32 of the respective stages are stacked in the same plane and face the roller brush 2. Specifically, as shown in fig. 5, the cleaning medium ejection ports 32 of the purge assembly 3 are arranged in four stages, i.e., a first-stage cleaning medium ejection port 321, a second-stage cleaning medium ejection port 322, a third-stage cleaning medium ejection port 323, and a fourth-stage cleaning medium ejection port 324; wherein the first-stage cleaning medium ejection port 321 communicates with the cleaning medium inlet 31 through the first-stage flow path branch 33, the second-stage cleaning medium ejection port 322 is disposed below and connected to the first-stage cleaning medium ejection port 321 through the second-stage flow path branch 34, the third-stage cleaning medium ejection port 323 is disposed below and connected to the second-stage cleaning medium ejection port 322 through the third-stage flow path branch 35, the fourth-stage cleaning medium ejection port 324 is disposed below and connected to the third-stage cleaning medium ejection port 323 through the fourth-stage flow path branch 36, the cleaning medium ejection ports 32 of the respective stages are disposed toward the surface of the roll brush, and finally the cleaning medium is ejected to the surface of the roll brush through the fourth-stage cleaning medium ejection port 324. Among them, the first-stage cleaning medium ejection openings 321 have 2 cleaning medium ejection openings 32, the second-stage cleaning medium ejection openings 322 have 4 cleaning medium ejection openings 32, the third-stage cleaning medium ejection openings 323 have 8 cleaning medium ejection openings 32, and the fourth-stage cleaning medium ejection openings 324 have 16 cleaning medium ejection openings 32. It is understood that there are also a plurality of levels of cleaning medium ejection openings 32, and the number of corresponding cleaning medium ejection openings 32 is also large; which are all the protection scope of the present embodiment.

Note that the four levels of flow path branches are located in the same plane so that the four levels of cleaning medium ejection openings 32 are arranged in a superimposed manner in the same plane. For example, in the radial direction of the roll brush 2, with the fourth-stage cleaning medium ejection openings 324 as the observation starting point (as viewed from the bottom up in fig. 5), only the fourth-stage cleaning medium ejection openings 324 can be observed; alternatively, only the cleaning medium ejection openings 32 arranged in a straight line can be observed in the radial direction of the roll brush 2, starting from the cleaning medium inlet 31 (viewed from the top to the bottom in fig. 5).

It should be further noted that the four levels of flow channel branches may be set to be equal in length, that is, the four levels of flow channel branches from the first-level flow channel branch 33 to the fourth-level flow channel branch 36 are equal; the flow path branches of the respective stages may be set to different lengths, that is, the first-stage flow path branch 33, the second-stage flow path branch 34, the third-stage flow path branch 35, and the fourth-stage flow path branch 36 are not equal, as long as the flow path branches in one stage are equal, for example, there are 8 third-stage flow path branches 35, and the 8 third-stage flow path branches 35 are equal in length.

As shown in fig. 1, fig. 6 and fig. 7, the second cleaning assembly 3 is configured such that the flow path branches connected to the cleaning medium injection ports 32 of each level are located in different planes, so that the cleaning medium injection ports 32 of each level are disposed in a stacked manner in the different plane spaces. Specifically, as shown in fig. 6, the cleaning medium ejection ports 32 of the purge assembly 3 are arranged in four stages, i.e., a first-stage cleaning medium ejection port 321, a second-stage cleaning medium ejection port 322, a third-stage cleaning medium ejection port 323, and a fourth-stage cleaning medium ejection port 324; wherein the first-stage cleaning medium ejection port 321 communicates with the cleaning medium inlet 31 through the first-stage flow path branch 33, the second-stage cleaning medium ejection port 322 is connected with the first-stage cleaning medium ejection port 321 through the second-stage flow path branch 34, the third-stage cleaning medium ejection port 323 is connected with the second-stage cleaning medium ejection port 322 through the third-stage flow path branch 35, the fourth-stage cleaning medium ejection port 324 is connected with the third-stage cleaning medium ejection port 323 through the fourth-stage flow path branch 36, the cleaning medium ejection ports 32 of the respective stages are disposed toward the surface of the roll brush, and finally the cleaning medium is ejected to the surface of the roll brush through the fourth-stage cleaning medium ejection port 324. Among them, the first-stage cleaning medium ejection openings 321 have 2 cleaning medium ejection openings 32, the second-stage cleaning medium ejection openings 322 have 4 cleaning medium ejection openings 32, the third-stage cleaning medium ejection openings 323 have 8 cleaning medium ejection openings 32, and the fourth-stage cleaning medium ejection openings 324 have 16 cleaning medium ejection openings 32. Of course, there are also a plurality of levels of cleaning medium ejection openings 32, and the number of corresponding cleaning medium ejection openings 32 is also large; which are all the protection scope of the present embodiment.

It should be noted that the four levels of flow channel branches are located in different planes, so that the four levels of cleaning medium ejection openings 32 are spatially stacked in the different planes; specifically, the first-stage cleaning medium ejection openings 321 are located in a first plane (not shown in fig. 6) in the radial direction of the roll brush 2 (the direction from the top to the bottom in fig. 6); the second-tier cleaning medium ejection openings 322 are located in a second plane (not shown in fig. 6) in the radial direction of the roll brush 2; the third-tier cleaning medium ejection openings 323 are located in a third plane in the radial direction of the roll brush 2 (not shown in fig. 6); the fourth-tier cleaning medium ejection openings 324 are located in a fourth plane (not shown in fig. 6) in the radial direction of the roll brush 2; the first plane, the second plane, the third plane, and the fourth plane are parallel to each other in the radial direction of the roll brush 2, so that four levels of the cleaning medium ejection openings 32 are stacked in the radial direction perpendicular to the roll brush 2, thereby forming a spatial stack in different planes.

Further, as shown in fig. 6 and 7, the first-stage cleaning medium ejection port 321 is a first distance from the surface of the roll brush, the second-stage cleaning medium ejection port 322 is a second distance from the surface of the roll brush, the third-stage cleaning medium ejection port 323 is a third distance from the surface of the roll brush, and the fourth-stage cleaning medium ejection port 324 is a fourth distance from the surface of the roll brush. Wherein the first distance, the second distance, the third distance and the fourth distance may be equal or different; for example, the first-stage cleaning medium ejection port 321 and the second-stage cleaning medium ejection port 322 are approximately equal in distance from the surface of the roller brush, and are located at the same height from the surface of the roller brush, the third-stage cleaning medium ejection port 323 and the fourth-stage cleaning medium ejection port 324 are approximately equal in distance from the surface of the roller brush, and the third distance (or the fourth distance) is smaller than the first distance (or the second distance), and the third-stage cleaning medium ejection port 323 and the fourth-stage cleaning medium ejection port 324 are located lower than the first-stage cleaning medium ejection port 321 and the second-stage cleaning medium ejection port 322 and are located close to the surface of the roller brush; for another example, if the first distance is greater than the second distance and greater than the third distance and greater than the fourth distance, the first-stage cleaning medium ejection openings 321 to the fourth-stage cleaning medium ejection openings 324 are sequentially disposed away from the cleaning medium inlet 31. Of course, the distance relationship between the cleaning medium ejection openings 32 of the respective stages is still other, and it is within the scope of the present embodiment to achieve the overlapping of the cleaning medium ejection openings 32 of the four stages in the radial direction of the roll brush 2.

As is apparent from the above, the four levels of the cleaning medium ejection openings 32 are arranged in a superimposed manner in the radial direction of the roll brush 2 and in the radial direction perpendicular to the roll brush 2, so that the four levels of the cleaning medium ejection openings 32 are arranged in a superimposed manner in the spatial dimension. Compared with the first cleaning assembly 3 structure, the cleaning assembly 3 of the second structure enables the multi-stage flow channel branches to be separated and superposed in space, so that the occupied space of the cleaning medium injection port 32 is reduced, and the volume of the cleaning assembly 3 is reduced.

It should be further noted that the four levels of flow path branches may be set to be equal in length, i.e., the first-level flow path branch 33 to the fourth-level flow path branch 36 are equal; the flow path branches of the respective stages may be set to different lengths, that is, the first-stage flow path branch 33, the second-stage flow path branch 34, the third-stage flow path branch 35, and the fourth-stage flow path branch 36 may be different, as long as the plurality of flow path branches of one stage are equal.

It will be appreciated that the water pressure of the cleaning medium ejection port 32 near the surface of the roll brush becomes smaller and smaller due to the increase in the length of the flow path, and in order to increase the water pressure, referring to fig. 4, an air pump 8 or a liquid pump (not shown) may be connected to the cleaning medium inlet 31. Because the air pump 8 or the liquid pump is a mature product device, the description will not be repeated here.

Further, in order to enhance the cleaning effect, the cleaning apparatus 100 is further provided with a liquid squeezing member 4, and the liquid squeezing member 4 is disposed on the housing 1 above the cleaning medium ejection port 32 and contacts the surface of the roll brush in the axial direction of the roll brush 2. In the embodiment, after the cleaning medium jet port 32 jets the liquid onto the surface of the roller brush, the liquid squeezing piece 4 can squeeze the liquid on the surface of the roller brush, so that the liquid is uniformly dispersed on the surface of the roller brush again, that is, the liquid point jetted from the cleaning medium jet port 32 onto the surface of the roller brush by the liquid squeezing piece 4 is uniformly changed into line uniformity; and the liquid squeezing piece 4 is arranged on the surface of the rolling brush in an interference manner, so that the deep dirt in the rolling brush 2 can be cleaned. Wherein, crowded liquid spare 4 is the doctor blade muscle of flexible material or stereoplasm material.

In the present embodiment, in order to make the liquid squeezed out of the liquid-squeezing member 4 from the surface of the roll brush uniformly clean the surface of the roll brush again, there is further provided a groove 5, the groove 5 is provided between the liquid-squeezing member 4 and the cleaning medium ejection port 32 and extends in the axial direction of the roll brush 2, the notch of the groove 51 faces the surface of the roll brush, and the contact surface of the groove 51 is in contact with the surface of the roll brush. Specifically, the groove 51 is provided in two structures, one of which is a U-shaped groove 51 as shown in fig. 8, and a liquid storage tank (not shown) of the U-shaped groove 51 can receive the liquid squeezed out from the roller brush surface by the liquid squeezing member 4, and after the liquid storage tank is full of the liquid, the liquid is uniformly drained to the roller brush surface again through a contact surface in the liquid storage tank, which is in contact with the roller brush surface. The other type of groove 51 is a die groove 52 as shown in fig. 9, and a liquid storage tank (not shown) of the die groove 52 can receive the liquid squeezed out from the roll brush surface by the liquid squeezing member 4 and drain the liquid uniformly to the roll brush surface again through a contact surface in the liquid storage tank, which is in contact with the roll brush surface, after the liquid storage tank is full of the liquid. Namely, through the contact of liquid in the liquid storage tank and the surface of the rolling brush, the line of the cleaning medium extruded by the liquid extruding piece 4 is uniformly changed into the uniform surface, and the rolling brush 2 is further uniformly and comprehensively cleaned, so that the cleaning efficiency and the cleaning degree of the rolling brush 2 are improved.

Furthermore, in combination with the above, as the rolling brush 2 rotates, part of the dirt on the surface of the rolling brush is absorbed in the air suction pipeline 7, and then the dirt is collected in the solid collecting barrel and the liquid collecting barrel connected with the solid collecting barrel through the air suction pipeline 7, and the dirt which is not absorbed rotates to the position of the cleaning medium jet orifice 32, in order to reduce the difficulty of cleaning the surface of the rolling brush by the cleaning medium jet orifice 32, in this embodiment, the cleaning device 100 is further provided with the dirt removing member 6, and the dirt removing member 6 is arranged on the housing 1 and located below the cleaning medium jet orifice 32, and contacts with the surface of the rolling brush along the axial direction of the rolling brush 2; the air suction opening of the air suction pipeline 7 is positioned below the dirt removing part 6.
