This application is, however, susceptible of embodiment in many other ways than those herein described and similar generalizations can be made by those skilled in the art without departing from the spirit of the application and the application is therefore not limited to the specific embodiments disclosed below.

A first embodiment of the present application provides a cleaning device 100, and fig. 1 is a schematic structural diagram of the cleaning device 100 provided in the first embodiment of the present application.

As shown in conjunction with fig. 1 and 2, embodiments of the present application provide a cleaning device 100 comprising: a housing 1, a roller brush 2 and a cleaning assembly 3. Wherein the housing 1 includes a front end housing (not shown), a support housing 11, a side plate cover 12, and a base housing 13; the front end shell is arranged in front of the shell 1, the structure of the front end shell is arc-shaped, and the rolling brush 2 can be accommodated and installed, and the rolling brush 2 is arranged in the front end shell through the side plate cover 12 and can rotate relative to the front end shell; the supporting shell 11 is connected with the front end shell and is arranged away from the rolling brush 2 along the horizontal direction; the base shell 13 is connected with the support shell 11 and is positioned below the shell 1; the area between the support housing 11 and the base housing 13 is the suction duct 7, and the suction inlet of the suction duct 7 is close to and faces the surface of the rolling brush, and is lower than the central axis of the rolling brush 2, so that when dirt (solid or liquid) is separated from the surface of the rolling brush, the dirt can be absorbed in the suction duct 7, and the dirt is collected into a solid collecting barrel and a liquid collecting barrel connected with the dirt collecting barrel through the suction duct 7, so that the dirt separated from the surface of the rolling brush can be prevented from being scattered on the ground again, and the cleaning surface is polluted again.

With continued reference to fig. 1, the cleaning device 100 of the present embodiment is for achieving uniform cleaning of the rolling brush 2. Wherein the cleaning of dirt on a cleaning surface (e.g. floor) by the cleaning device 100 is accomplished by the roller brush 2, which surface becomes dirty due to the cleaning of dirt, so that the roller brush 2 needs to be cleaned by the cleaning assembly 3. Specifically, the cleaning of the rolling brush 2 can be achieved based on the cooperation of the rolling brush 2 and the cleaning component 3, and the cleaning component 3 has a specific position area corresponding to the surface of the rolling brush, the area where the rolling brush 2 cooperates with the cleaning component 3 is set as a cleaning area (a sector area with the center of the rolling brush 2 facing the horizontal direction, namely, an area a in fig. 1); the surface of the roller brush is cleaned by the cleaning assembly 3 when passing through the cleaning area of the roller brush 2 along with the rotation (arrow direction) of the roller brush 2, so that the surface of the roller brush is clean.

Specifically, as shown in fig. 1 and 2, the cleaning component 3 is disposed on the supporting housing 11, the cleaning component 3 is disposed towards the roller brush 2 and higher than the central axis of the roller brush 2, and is located above the air suction pipe 7, so that the cleaning component 3 is convenient for cleaning the end face of the roller brush 2, and dirt separated from the surface of the roller brush after cleaning can fall into the air suction pipe 7, and then is collected into the solid collecting barrel and the liquid collecting barrel connected with the air suction pipe 7 through the air suction pipe, so that the dirt separated from the surface of the roller brush can be prevented from being scattered on the ground again, and the ground is polluted again.

In the present embodiment, the cleaning assembly 3 includes the cleaning medium inlet 31 for filling the cleaning medium of the cleaning roller brush 2 and the plurality of cleaning medium ejection openings 32, the cleaning medium ejection openings 32 for releasing the cleaning medium of the cleaning roller brush 2, and the cleaning medium inlet 31 and the plurality of cleaning medium ejection openings 32 communicate so that the cleaning medium entering the cleaning medium inlet 31 is ejected from the cleaning medium ejection openings 32. In the present embodiment, the cleaning medium inlet 31 is provided as one, so that the medium filling of the cleaning roller brush 2 is more concentrated, and the filling operation is facilitated; it is also possible to make the time for the cleaning medium to flow from the cleaning medium inlet 31 to the plurality of cleaning medium ejection openings 32 the same so that the cleaning medium ejected from the plurality of cleaning medium ejection openings 32 reaches the surface of the roller brush uniformly; wherein the lengths of the flow paths between the cleaning medium inlet 31 and the plurality of cleaning medium ejection openings 32 are equal. Of course, the cleaning medium inlet 31 may be provided in plural and directed toward the roll brush surface; the embodiments of the present application are intended to protect as long as the amount of the cleaning medium reaching the plurality of cleaning medium ejection openings 32 can be equalized. The cleaning medium ejection openings 32 are provided in plural numbers in order to increase the coverage area of the cleaning medium ejection openings 32 on the surface of the roller brush, thereby increasing and homogenizing the contact area of the ejected cleaning medium with the surface of the roller brush, and further improving the cleaning effect of the roller brush 2.

It should be noted that, the cleaning medium in this embodiment may be a liquid, a gas, or a gas-liquid mixture, and in this embodiment, the surface of the roller brush may be cleaned by the liquid ejected from the cleaning medium ejection opening 32, or the surface of the roller brush may be cleaned by the gas-liquid mixture ejected from the cleaning medium ejection opening 32.

In the preferred embodiment of the present embodiment, the plurality of cleaning medium ejection openings 32 are directed toward the surface of the roll brush, and at least part of the cleaning medium ejection openings 32 are arranged in the axial direction of the roll brush 2, and the cleaning medium ejection openings 32 arranged in the axial direction of the roll brush 2 are equally spaced. It will be appreciated that the number of the cleaning medium ejection openings 32 of the present embodiment is large, and based on the rotation of the roll brush 2 about the axial direction, at least a part of the cleaning medium ejection openings 32 may be arranged in the axial direction of the roll brush 2 such that the part of the cleaning medium ejection openings 32 covers a straight line of the roll brush surface in the axial direction, so that the part of the cleaning medium ejection openings 32 arranged in the axial direction may cover the entire roll brush surface as the roll brush 2 rotates. The intervals between the cleaning medium ejection openings 32 are set to be equal distances also for the purpose of uniformly and continuously spraying the cleaning medium to the entire brush surface by uniformly and continuously coating the brush surface with the respective cleaning medium ejection openings 32 on a straight line in the axial direction.

It should be noted that, in this embodiment, the cleaning medium is uniformly sprayed onto the entire surface of the rolling brush, mainly according to the flow path balancing principle, as shown in the flow path schematic diagram of the cleaning assembly 3, which is shown in fig. 3, the lengths of the flow paths from each cleaning medium spraying port 32 to the cleaning medium inlet 31, which are arranged along the axial direction of the rolling brush 2, are the same, so that the amounts of the cleaning medium sprayed from each cleaning medium spraying port 32 are substantially the same, thereby realizing the uniform spraying of the cleaning medium onto the entire surface of the rolling brush, achieving the overall cleaning of the rolling brush 2, and improving the cleaning effect.

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

That is, the longer the flow passage is extended, the more the stages are, while the flow passages of the respective stages are provided as a plurality of branches, and the flow passage branch lengths of one stage are equal, so that the flow passage lengths between the cleaning medium ejection openings 32 and the cleaning medium inlets 31 in the respective stages are equal, and the specifications of the flow passages are uniform, so that the cleaning medium ejected from the plurality of cleaning medium ejection openings 32 is more uniform. In addition, since the cleaning medium ejection openings 32 are provided in a multi-stage structure, the cleaning medium ejection openings 32 of each stage are stacked, that is, the stacked arrangement is such that all the cleaning medium ejection openings 32 of one stage are stacked as a whole with all the cleaning medium ejection openings 32 of the other stage as a whole.

In the present embodiment, the cleaning medium ejection openings 32, which are integrally stacked in a hierarchy, include two structures in which the cleaning members 3 are provided in two structures; as shown in fig. 1 and 5, the first cleaning unit 3 is configured such that the flow path branches to which the cleaning medium ejection openings 32 of the respective stages are connected are located on the same plane, so that the cleaning medium ejection openings 32 of the respective stages are stacked on the same plane and face the rolling brush 2. Specifically, as shown in fig. 5, the cleaning medium ejection openings 32 of the cleaning assembly 3 are arranged in four stages, i.e., a first stage cleaning medium ejection opening 321, a second stage cleaning medium ejection opening 322, a third stage cleaning medium ejection opening 323, and a fourth stage cleaning medium ejection opening 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 all disposed toward the rolling brush surface, and finally the cleaning medium is ejected to the rolling brush surface through the fourth-stage cleaning medium ejection port 324. Among them, the first-stage cleaning medium ejection port 321 has 2 cleaning medium ejection ports 32, the second-stage cleaning medium ejection port 322 has 4 cleaning medium ejection ports 32, the third-stage cleaning medium ejection port 323 has 8 cleaning medium ejection ports 32, and the fourth-stage cleaning medium ejection port 324 has 16 cleaning medium ejection ports 32. It will be appreciated that there are a plurality of levels of cleaning medium ejection openings 32 and a corresponding number of cleaning medium ejection openings 32; which are all intended to be protected by this embodiment.

The flow path branches of the four stages are located in the same plane so that the cleaning medium ejection ports 32 of the four stages are disposed in superposition 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 start point (from bottom to top in fig. 5), only the fourth-stage cleaning medium ejection openings 324 can be observed; or, in the radial direction of the roll brush 2, only the cleaning medium ejection openings 32 distributed on a straight line can be observed with the cleaning medium inlet 31 as an observation start point (from the top to the bottom in fig. 5).

It should be further noted that the four-level flow path branches may be set to have equal lengths, that is, the four-level flow path branches of 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 have different lengths, that is, the first stage flow path branch 33 is different from the second stage flow path branch 34, the third stage flow path branch 35, and the fourth stage flow path branch 36, so long as the flow path branches in one stage are equal, for example, 8 third stage flow path branches 35 are provided, and the lengths of these 8 third stage flow path branches 35 are equal.

With continued reference to fig. 1, 6 and 7, the second cleaning module 3 is configured such that the flow paths of the cleaning medium ejection openings 32 of each level are located in different planes, so that the cleaning medium ejection openings 32 of each level are spatially stacked on the different planes. Specifically, as shown in fig. 6, the cleaning medium ejection openings 32 of the cleaning assembly 3 are arranged in four stages, i.e., a first stage cleaning medium ejection opening 321, a second stage cleaning medium ejection opening 322, a third stage cleaning medium ejection opening 323, and a fourth stage cleaning medium ejection opening 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 all disposed toward the rolling brush surface, and finally the cleaning medium is ejected to the rolling brush surface through the fourth-stage cleaning medium ejection port 324. Among them, the first-stage cleaning medium ejection port 321 has 2 cleaning medium ejection ports 32, the second-stage cleaning medium ejection port 322 has 4 cleaning medium ejection ports 32, the third-stage cleaning medium ejection port 323 has 8 cleaning medium ejection ports 32, and the fourth-stage cleaning medium ejection port 324 has 16 cleaning medium ejection ports 32. Of course, there are a plurality of levels of cleaning medium ejection openings 32, and there are a large number of corresponding cleaning medium ejection openings 32; which are all intended to be protected by this embodiment.

It should be noted that the flow path branches of the four stages are located in different planes so that the cleaning medium ejection openings 32 of the four stages are spatially superimposed on the above-described different planes; specifically, the first-stage cleaning medium ejection openings 321 are located in a first plane (not shown in fig. 6) along the radial direction (top-to-bottom direction in fig. 6) of the roll brush 2; the second-stage cleaning medium ejection opening 322 is located in a second plane in the radial direction of the roll brush 2 (not shown in fig. 6); the third-stage cleaning medium ejection opening 323 is located in a third plane (not shown in fig. 6) in the radial direction of the roll brush 2; the fourth-stage cleaning medium ejection opening 324 is located in a fourth plane in the radial direction of the roll brush 2 (not shown in fig. 6); 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 the four levels of cleaning medium ejection openings 32 are superimposed in the radial direction perpendicular to the roll brush 2, thereby forming spatial superimposition in different planes.

Further, as shown in fig. 6 and 7, the first-stage cleaning medium ejection opening 321 is spaced from the surface of the roll brush, the second-stage cleaning medium ejection opening 322 is spaced from the surface of the roll brush, the third-stage cleaning medium ejection opening 323 is spaced from the surface of the roll brush, and the fourth-stage cleaning medium ejection opening 324 is spaced 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 unequal; for example, the distances between the first-stage cleaning medium ejection opening 321 and the second-stage cleaning medium ejection opening 322, which correspond to the rolling brush surface, are substantially equal, the distances between the third-stage cleaning medium ejection opening 323 and the fourth-stage cleaning medium ejection opening 324, which correspond to the rolling brush surface, are substantially equal, 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 opening 323 and the fourth-stage cleaning medium ejection opening 324 are lower than the first-stage cleaning medium ejection opening 321 and the second-stage cleaning medium ejection opening 322, which are disposed close to the rolling brush surface; 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 through fourth stage cleaning medium ejection openings 321 through 324 are sequentially disposed away from the cleaning medium inlet 31. Of course, the relationship between the distances of the cleaning medium ejection openings 32 of the respective stages is also other, and is within the scope of the present embodiment as long as the four stages of the cleaning medium ejection openings 32 are superimposed in the radial direction of the roller brush 2.

As is clear from the above, the four layers of the cleaning medium ejection openings 32 are disposed in a superimposed manner in the radial direction of the roll brush 2 and in the radial direction of the vertical roll brush 2, so that the four layers of the cleaning medium ejection openings 32 are disposed in a superimposed manner in the spatial dimension. The cleaning module 3 of the second structure allows the multi-stage flow path branches to be stacked in space with respect to the first cleaning module 3 structure, thereby reducing the occupation space of the cleaning medium ejection port 32 and thus reducing the volume of the cleaning module 3.

It should be further noted that the four-level flow path branches may be provided to be equal in length, that is, 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 provided in different lengths, that is, the first stage flow path branch 33 is different from the second stage flow path branch 34, the third stage flow path branch 35, and the fourth stage flow path branch 36, so long as the flow path branches of one stage are equal.

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

Further, in order to enhance the cleaning effect, the cleaning device 100 is further provided with a liquid squeezing member 4, and the liquid squeezing member 4 is provided on the housing 1 above the cleaning medium ejection opening 32 and in contact with the surface of the roller brush in the axial direction of the roller brush 2. In the present embodiment, after the cleaning medium ejection opening 32 ejects the liquid onto the surface of the roll brush, the liquid squeezing member 4 may squeeze the liquid on the surface of the roll brush, so that the liquid is uniformly dispersed again onto the surface of the roll brush, that is, the liquid points of the cleaning medium ejection opening 32 ejected onto the surface of the roll brush are uniformly converted into lines by the liquid squeezing member 4; and the liquid squeezing piece 4 is in interference arrangement with the surface of the rolling brush, so that deep dirt in the rolling brush 2 can be cleaned. Wherein, the liquid squeezing piece 4 is a flexible material or a hard material of a scraping plate rib.

In this embodiment, in order to uniformly clean the surface of the roll brush again by the liquid extruded from the roll brush surface by the liquid extruding member 4, a groove 5 is further provided, the groove 5 is provided between the liquid extruding 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 grooves 51 are 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 extruded from the surface of the rolling brush by the liquid extruding member 4 and uniformly drain the liquid to the surface of the rolling brush again through a contact surface in the liquid storage tank, which is contacted with the surface of the rolling brush, after the liquid storage tank is full of the liquid. Another type of groove 51 is shown in fig. 9 as a die groove 52, and a liquid reservoir (not shown) of the die groove 52 is capable of receiving liquid extruded from the surface of the roller brush by the liquid extruding member 4 and uniformly draining the liquid to the surface of the roller brush again through a contact surface in the liquid reservoir, which contacts the surface of the roller brush, after the liquid reservoir is full of liquid. That is, the line of the squeezing member 4 squeezing the cleaning medium is changed into the surface uniformity by the surface contact of the liquid in the liquid storage tank and the rolling brush, so that the rolling brush 2 is further cleaned uniformly and comprehensively, and the cleaning efficiency and the cleaning degree of the rolling brush 2 are improved.

Still further, as can be seen from the foregoing, as the rolling brush 2 rotates, part of the dirt on the surface of the rolling brush is absorbed in the suction duct 7, and then the dirt is collected into the solid collecting barrel and the liquid collecting barrel connected with the suction duct 7, and the unabsorbed dirt is rotated to the position of the cleaning medium jetting port 32, so as to reduce the difficulty in cleaning the surface of the rolling brush by the cleaning medium jetting port 32, in this embodiment, the cleaning device 100 is further provided with a dirt removing member 6, and the dirt removing member 6 is disposed on the housing 1 and below the cleaning medium jetting port 32 and is in contact with the surface of the rolling brush along the axial direction of the rolling brush 2; the suction inlet of the suction pipe 7 is positioned below the dirt removing member 6. The dirt removing member 6 is in interference arrangement with the surface of the rolling brush, so that dirt which is not absorbed by the air suction pipeline 7 can be hung from the surface of the rolling brush, and the relatively clean surface of the rolling brush enters into a cleaning position of the cleaning medium jet orifice 32, wherein the dirt removing member 6 is a dirt removing plate bar made of flexible materials or hard materials.

A first embodiment of the present application provides a cleaning device 100 comprising: a housing 1, a roller brush 2 and a cleaning assembly 3; wherein the cleaning assembly 3 includes a cleaning medium inlet 31 and a plurality of cleaning medium ejection openings 32; the plurality of cleaning medium ejection openings 32 face the roller brush 2, and at least part of the cleaning medium ejection openings 32 are arranged along the axial direction of the roller brush 2, and the cleaning medium ejection openings 32 arranged along the axial direction of the roller brush 2 are equally spaced; the lengths of the flow paths from the respective cleaning medium ejection openings 32 to the cleaning medium inlet 31 provided in the axial direction of the roll brush 2 are the same.
