Referring now to fig. 1-15, a floor brush 100 according to some embodiments of the present invention is described, wherein the floor brush 100 according to the embodiments may be used in a variety of cleaning devices, such as a washing machine, a mopping machine, or a wet and dry cleaner.

With continued reference to fig. 1-7, the floor brush 100 of the present embodiment includes a body 10, a fluid injection assembly 11 disposed in the body 10, and a roller brush assembly 12 connected to the body 10, wherein the roller brush assembly 12 includes a cover plate 120, a roller brush 121, and a filter assembly detachably disposed on the cover plate 120, the cover plate 120 defines a roller brush accommodating cavity 120a, the roller brush 121 is rollably disposed in the roller brush accommodating cavity 120a, the filter assembly includes a filter screen 122, and at least a portion of the filter screen 122 is located between the roller brush 121 and the fluid injection assembly 11.

It should be noted that the cover plate 120 in this embodiment is a part of the rolling brush assembly 12, but the present invention is not limited thereto, and in other embodiments of the present invention, the rolling brush assembly 12 may at least include the rolling brush 121, and the cover plate 120 may also be provided separately from the rolling brush assembly 12, that is, the cover plate 120 and the rolling brush 121 may be two separate parts which are completely separated and can be respectively connected with the body 10.

In some other embodiments of the present invention, the filter assembly may be detachably disposed on the body 10, and when the filter assembly needs to be cleaned, the filter assembly is detached from the body 10.

Specifically, the fluid ejection assembly 11 is connected to the body 10. The "fluid ejection assembly 11" herein may refer to a component that supplies liquid or gas, for example, which may provide water, liquid with detergent, or water vapor to the floor brush 100, and the like.

The fluid injection assembly 11 includes a water outlet grid 110 and a plurality of injection ports 111 disposed on the water outlet grid 110, wherein the water outlet grid 110 is elongated, the water outlet grid 110 extends along a length direction (which may also be understood as an axial direction) of the rolling brush 121, the plurality of injection ports 111 are arranged along the length direction of the rolling brush 121, and the plurality of injection ports 111 may be configured to inject fluid to the rolling brush 121.

In the present embodiment, the ejection directions of the plurality of ejection openings 111 may be set to eject toward the roll brush 121, that is, in the present embodiment, the ejection directions of the plurality of ejection openings 111 are the same.

Further, it is also worth noting that when a plurality of injection ports 111 are provided, the injection direction of one part of the injection ports 111 and the injection direction of the other part of the injection ports 111 can be set to be different, for example, the injection direction of one part of the injection ports 111 can be set to be injected towards the rolling brush 121 for wetting the rolling brush 121, when the rolling brush 121 is wetted with fluid (for example, the rolling brush 121 is in a wet state), the impurities and the dirt on the surface to be cleaned can be cleaned by the rolling brush 121; as another example, the spraying direction of another part of the spraying ports 111 may be set to face the surface to be cleaned for wetting the surface to be cleaned, and when the rolling brush 121 passes over the surface to be cleaned with dirt, the rolling brush 121 may take away the dirt while wiping the surface to be cleaned clean.

When the cleaning device performs the surface cleaning operation, the injection port 111 injects a fluid (e.g., water or steam) toward the roller brush 121 for wetting the roller brush 121, and when the roller brush 121 is wetted with the fluid (e.g., the roller brush 121 is in a wet state), the roller brush 121 is beneficial to clean the impurities and stains on the surface to be cleaned. It should be noted that when the roller brush 121 performs surface cleaning, the dirt thrown off by the roller brush 121 adheres to the water outlet grid 110 and the injection port 111, and the injection port 111 is easily blocked by long-term uncleaning. In order to solve the above problem, in the present embodiment, the strainer 122 is connected to the cover plate 120, and a portion of the strainer 122 is located between the roller brush 121 and the fluid injection assembly 11, so that when the roller brush 121 rotates, the thrown dirt is blocked by the strainer 122, and the dirt is greatly reduced from entering the water outlet grill 110 and the injection port 111 (i.e., the fluid injection assembly 11). Therefore, when cleaning is needed at ordinary times, only the rolling brush assembly 12 needs to be detached from the body 10 for cleaning, and the fluid spraying assembly 11 does not need to be detached for cleaning, so that the pain point of frequently cleaning the fluid spraying assembly 11 is solved.

In the present embodiment, with continued reference to fig. 2, the roller brush 121 is cylindrical, and the roller brush 121 rotates around the central rotation axis in one direction, thereby driving the cleaning device to move forward. The cover plate 120, the body 10 and the roller brush 121 form an accommodating space, the filter screen 122 and the fluid injection assembly 11 are located in the accommodating space, and specifically, the filter screen 122 and the fluid injection assembly 11 are located on the rear upper side of the roller brush 121. The filter screen 122 in this embodiment may have a long strip shape, and the filter screen 122 extends along the length direction of the roller brush 121. In particular, the screen 122 may completely shield the fluid injection assembly 11 from sludges being thrown onto the fluid injection assembly 11.

With continued reference to fig. 3, the body 10 has a water return port 101, the water return port 101 communicates with the rolling brush accommodating chamber 120a, and the fluid ejected from the ejection port 111 can be recovered through the water return port 101, so that the surface to be cleaned can be drier and tidier, the fluid in the liquid state is prevented from remaining on the surface to be cleaned, and the filter screen 122 can be disposed at a position close to the water return port 101. Further, the water returning port 101 is located downstream of the screen 122 in the forward moving direction of the cleaning apparatus. When the roller brush 121 rolls along the rolling direction thereof, a part of the liquid fluid on the roller brush 121 collides with the screen 122 along the rolling direction, and the liquid fluid moves toward the area in the opposite direction or the area in the opposite direction where the roller brush 121 rolls through the collision of the screen 122, so that the liquid fluid can fly into the water return port 101, and the fluid can be recovered.

With continued reference to fig. 4-7, in the present embodiment, the surface of the screen 122 facing the roller brush 121 may be configured to be flat, and in addition, at least a portion of the surface of the screen 122 facing the roller brush 121 may be configured to be an arc-shaped surface, which is coincident with at least a portion of the peripheral wall of the roller brush 121. Specifically, the sludge thrown onto the filter screen 122 by the rolling brush 121 can flow down quickly along the smooth arc-shaped surface of the filter screen 122, so as to reduce the excessive sludge accumulated on the filter screen 122. The embodiment does not limit this, and those skilled in the art can flexibly select the target according to the needs.

In this embodiment, with continued reference to fig. 3, there is a gap between the lower edge of the screen 122 and the peripheral wall of the roller brush 121. Specifically, the gap may serve as a water outlet gap of the fluid injection assembly 11, that is, the fluid injection assembly 11 may inject the fluid onto the roller brush 121 through the gap.

In some other embodiments of the present invention, the lower edge of the screen 122 is in contact with the peripheral wall of the drum brush 121. When the rolling brush 121 rotates, the dirt on the rolling brush 121 can be thrown onto the filter screen 122, so that the liquid or other impurities on the rolling brush 121 can be thrown off, the rolling brush 121 can be kept clean and dry, and the cleaning performance of the floor brush 100 can be improved.

Further, in this embodiment, with continued reference to fig. 3, the floor brush 100 further includes a scraper 13 disposed in the body 10, the scraper 13 is in a shape of a long strip and can extend along the length direction of the roller brush 121, and the free end of the scraper 13 contacts with the outer peripheral wall of the roller brush 121. Specifically, when the rolling brush 121 rotates, the sewage on the rolling brush 121 can be thrown onto the mud scraper 13, so that the liquid or other impurities on the rolling brush 121 can be thrown off, which is beneficial to keeping the rolling brush 121 clean and dry, and further can improve the cleaning performance of the floor brush 100.

In this embodiment, with continued reference to fig. 3, the roller brush assembly 12 is detachably connected to the main body 10 via the cover plate 120, so that when the roller brush 121 needs to be cleaned or repaired, the roller brush assembly 12 can be directly detached from the main body 10. Specifically, the body 10 is provided with a slide rail 102, the cover plate 120 is provided with a slider 120b, and the slider 120b is slidably inserted into the slide rail 102. At this time, the installation of the entire roller brush assembly 12 with respect to the body 10 can be achieved by the sliding assembly of the slider 120b with the slide rail 102. In cooperation with the slider 120b and the slide rail 102, a first locking structure may be further included, which is disposed on the body 10 and the cover 120, or the first locking structure may be disposed only on the body 10 or only on the cover 120 for locking and unlocking the sliding between the slider 120b and the slide rail 102. Therefore, when the first locking structure is unlocked, the slider 120b can slide relative to the slide rail 102, and the whole rolling brush assembly 12 can be mounted and dismounted by the relative sliding between the member 120b and the slide rail 102, and when the first locking structure is locked, the slider 120b cannot slide relative to the slide rail 102, and the whole rolling brush assembly 12 cannot be mounted and dismounted by the relative sliding between the slider 120b and the slide rail 102, but this can ensure that the rolling brush assembly 12 can be stably mounted on the body 10, and prevent the risk of falling.

In other embodiments of the present invention, the cover plate 120 may be fixedly connected to the body 10, and the connection manner between the cover plate 120 and the body 10 is not limited in this embodiment, and those skilled in the art may flexibly select the connection manner according to the needs.

It should be noted that, no matter the cover plate 120 is detachably connected or fixedly connected with the body 10, the filter assembly is detachably connected with the cover plate 120, so that when the filter assembly needs to be cleaned, the filter assembly is directly disassembled from the body 10.

In this embodiment, as shown in fig. 6-7, the floor brush 100 further includes a second locking structure for locking and unlocking the connection between the filter assembly and the cover plate 120. Specifically, when the filter element is installed in place, the second locking structure is controlled to lock the filter element, the filter element cannot move relative to the cover plate 120, and then the filter element is connected with the cover plate 120, accordingly, when the filter element needs to be detached, the second locking structure is controlled to be unlocked, the filter element is unlocked, the filter element can be detached from the cover plate 120, and the filter element can be cleaned.

Specifically, in this embodiment, with continued reference to fig. 6-7, the filter assembly further includes an inclined bar-shaped connecting plate 123 connected to the filter screen 122 and a lock case 124 disposed at a middle position of the connecting plate 123, and accordingly, two opposite protrusions 120c and a holding block 120d disposed between the two protrusions 120c protrude from the cover plate 120, the two protrusions 120c are disposed at an interval, and a lock slot 120e is disposed on the protrusion 120c, a second locking structure is disposed on the lock case 124, the second locking structure includes two toggle buttons 14 and two elastic members 15 disposed opposite to each other, the two toggle buttons 14 can move in a direction away from or close to each other, one elastic member 15 is disposed on each toggle button 14, wherein one end of each elastic member 15 is connected to the toggle button 14, and the other end is connected to the holding block 120d, the toggle button 14 has a toggle portion 140 and a lock portion 141, a notch 124a inserted into the lock portion 141 is disposed on the lock case 124, and the lock portion 141 is telescopically disposed in the notch 124 a. When the filter assembly needs to be unlocked, the toggle part 140 is toggled, the locking button 14 compresses the elastic piece 15, the locking part 141 is disengaged from the locking groove 120e and the notch 124a, the filter assembly is disengaged from the second locking structure, the filter assembly can be disassembled and cleaned, the toggle part 140 is released after the filter assembly is disassembled, and the locking part 141 resets under the action of the elastic piece 15. Correspondingly, after the cleaning is finished, the toggle part 140 is toggled, the locking button 14 compresses the elastic piece 15, the locking part 141 is separated from the locking groove 120e, the locking shell 124 of the filter assembly is installed in place at the moment, the locking groove 120e corresponds to the notch 124a in position, and the toggle part 140 is loosened, so that the locking of the filter assembly can be realized.

It should be noted that, the structure of the second locking structure is not limited in this embodiment, and it is within the protection scope of the present application as long as the locking and unlocking of the filter assembly and the cover plate 120 can be achieved.

In addition, in the existing cleaning machine, a larger distance can be actually existed between the end part of the floor brush and the edge of the cleaning machine, and the existence of the distance can cause the cleaning machine to have a cleaning blind area, such as a corner, a wall edge and the like, so that the floor brush can not smoothly clean dust and dirt in the blind area in the cleaning process, and the cleaning effect is influenced. The reason that current cleaning machine has clean blind area lies in, generally all set up driving motor at the tip of round brush when installing the round brush on current cleaning machine, and in order to guarantee round brush pivoted stability, most cleaning machine still can set up the structure of rotation support in the other one end of round brush, so, driving motor and rotation support's structure can occupy the space at round brush both ends, and make the both ends of round brush and the both ends of cleaning machine produce certain distance, this kind of distance can lead to the both ends of round brush can't stretch out the both ends of cleaning machine at all, even unable and the both ends parallel and level of cleaning machine, so when utilizing the cleaning machine to carry out ground cleaning, the both ends of cleaning machine have the blind area space of certain distance to clean not to arrive, the size of this blind area also depends on the distance of round brush tip and cleaning machine tip. In order to solve such a problem, the present application provides the following technical solutions. Referring to fig. 8-15, the floor brush 100 further comprises a hoisting member 16, one end of the hoisting member 16 is connected with the cover plate 120, and the other end of the hoisting member 16 is provided with a sleeve component 17; the rolling brush 121 is rotatably sleeved in the sleeving component 17 and can be supported and rotated in the sleeving component 17.

Therefore, the roller brush 121 in the floor brush 100 completely changes a completely new rotating assembly mode, the assembly mode of the driving motor and the rotating support structure is cancelled at the two ends of the roller brush 121, or at least the rotating support structure is cancelled, the improved structure of the floor brush 100 can at least leave the space occupied by the driving motor or the rotating support structure at one end of the roller brush 121, or even directly leave the space occupied by the driving motor or the rotating support structure at the two ends of the roller brush 121.

When the driving motor or the rotation supporting structure is eliminated, the rotation support of the rolling brush 121 is realized by using the sling 16, in this case, the sling 16 for mounting the rolling brush 121 is not connected to both ends of the rolling brush 121, but is directly mounted at the middle position of the rolling brush 121, and the middle position can be understood as the position other than both ends of the rolling brush 121 on the rolling brush 121, and does not only refer to the midpoint or the vicinity of the midpoint of the rolling brush 121, for example, the sling 16 can be connected to the left or right position of the rolling brush 121, and does not need to be completely located at the midpoint of the rolling brush 121. After the hoisting part 16 is connected with the rolling brush 121, the rolling brush 121 can be connected with the cover plate 120, so that the structural characteristics that only the central position of the rolling brush 121 has connection can be matched, and even after the hoisting part 16 is connected to the cover plate 120, a connection structure cannot be formed at two ends of the rolling brush 121, so that the spaces at two ends of the rolling brush 121 can be truly left, and the rolling brush can extend out of two ends of a cleaning machine, and the cleaning work of blind areas can be realized.

Therefore, after the rolling brush 121 is connected to the cover plate 120 through the hoisting member 16, the hoisting member 16 can continue to form a rotating assembly with the rolling brush 121 through the sleeving component 17, so that the rolling brush 121 can rotate in the sleeving component 17, when the corresponding driver 18 drives the rolling brush 121 to rotate, the rolling brush 121 can smoothly rotate in the sleeving component 17, and further the original basic function of the rolling brush ground is realized, the ground is cleaned by utilizing the rolling state of the rolling brush 121, therefore, the spaces at two ends of the rolling brush 121 can be left, so that two ends or at least one end of the rolling brush 121 can extend out of the cleaning machine, and the cleaning of the original blind area is realized.

For the socket component 17, the socket component 17 is used for rotatably assembling with the rolling brush 121, because the rolling brush 121 in the original structure is rotatably assembled to the rolling brush 121 through a driving motor or a shaft structure at the end of the rolling brush 121, and the rolling brush 121 is supported together, the socket component 17 also needs to simultaneously support the rolling brush 121 and allow the rolling brush 121 to rotate, so long as the assembly of the rolling brush 121 and the rotation of the rolling brush 121 in the socket component 17 can be realized, the socket component 17 may be an assembly structure formed by a plurality of components together, and actually may also be an individual component structure, for example, the socket component 17 may only include the bearing 170, the inner ring of the bearing 170 is socket-connected with the rolling brush 121, and the outer ring of the bearing 170 is connected with the hanger 16.

At this time, the inner ring and the outer ring of the bearing 170 can roll relatively through the balls in the bearing 170, as long as the outer ring of the bearing 170 is connected with the hoisting member 16, and the inner ring of the bearing 170 is sleeved with the rolling brush 121, the rolling brush 121 can rotate relatively through the inner ring and the outer ring of the bearing 170, so that the relative rotation of the rolling brush 121 relative to the hoisting member 16 is realized, after the hoisting member 16 is connected to the cover plate 120, the rolling brush 121 can also be indirectly connected with the cover plate 120, then the rolling brush 121 is assembled on the body 10 of the cleaning machine along with the assembly of the cover plate 120, the integral support and the rotating assembly of the rolling brush 121 are realized only through the sleeving assembly, and the space at two ends or at least one end of the rolling brush 121 is completely left. The bearing 170 may adopt various bearing 170 structures such as a deep groove ball bearing 170, an angular contact ball bearing 170, a thrust ball bearing 170, and the like, and a person skilled in the art may select a suitable type of bearing 170 according to an assembly requirement, which is not limited herein.

Of course, in addition, the sheathing assembly may also adopt other structures, for example, the sheathing assembly may constitute an annular component, and the annular component and the rolling brush 121 are sleeved, so long as the rolling brush 121 is driven to rotate in the annular component, and in order to reduce friction between the annular component and the rolling brush 121 and improve smoothness of rotation of the rolling brush 121, a shaft structure specially assembled with the annular component may be further disposed in the middle of the rolling brush 121, or a part of the shaft structure contacting with the annular component is polished, and such a structure is not described again.

In order to improve the stability of the rotational assembly between the bearing 170 and the rolling brush 121, the sleeve component 17 may further be configured to fit with corresponding auxiliary components according to the structural characteristics of the bearing 170, for example, the sleeve component 17 further includes a hanging ring 171 disposed at the other end of the hanging part 16 and sleeved with the outer ring of the bearing 170. The hanging ring 171 is a component with an annular structure, and by utilizing the annular structure characteristics of the hanging ring 171, the hanging ring 171 can be directly sleeved with the outer ring of the bearing 170, and the inner annular surface of the hanging ring 171 can be in one-circle continuous contact with the outer surface of the outer ring of the bearing 170 in the sleeved mode, so that a larger contact area can be formed on the outer ring of the bearing 170 based on the annular structure characteristics of the outer ring of the bearing 170, and fixed contact can be formed at each position in the circumferential direction, and therefore, the assembly stability of the sleeved assembly 17 can be effectively improved. Moreover, as shown in fig. 14-15, after the hanging ring 171 is sleeved with the outer ring of the bearing 170, the hanging ring 171 is connected with the hanging piece 16, which is more convenient than the way that the hanging piece 16 is directly connected with the outer ring of the bearing 170, and based on the original structure of the outer ring of the bearing 170, only the hanging ring 171 needs to be sleeved with the outer ring of the bearing 170.

For the rolling brush 121, the rolling brush 121 may be an integral structure or a split structure, when the rolling brush 121 is an integral structure, the corresponding socket component 17 may directly form a rotational assembly with any position of the rolling brush 121, or a structure suitable for the socket component 17 to perform the rotational assembly may also be formed at a corresponding position of the rolling brush 121, for example, a shaft structure convenient for the rotational assembly is disposed at a corresponding position of the rolling brush 121, so as to facilitate the socket component 17 and the rolling brush 121 to form the rotational assembly, when the rolling brush 121 is a split structure, the rolling brush 121 may be actually split into two or more sections, and when the two or more sections are axially connected with each other, the complete rolling brush 121 may be spliced, and this split rolling brush 121 structure has an advantage that a gap may be formed between adjacent sections of the two or more sections, thereby forming a shaft structure convenient for the rotational assembly of the socket component 17.

Referring to fig. 8 to 11, the roll brush 121 includes a first cylindrical brush 121a and a second cylindrical brush 121b, the first cylindrical brush 121a and the second cylindrical brush 121b are coaxially connected by a connection part 172, and an inner ring of the bearing 170 is sleeved with the connection part 172. At this time, the roll brush 121 is divided into two segments to form a split structure after being composed of the first and second cylindrical brushes 121a and 121 b. When the first cylindrical brush 121a and the second cylindrical brush 121b are axially and coaxially connected, a gap can be formed between the inner end of the first cylindrical brush 121a and the inner end of the second cylindrical brush 121b, the gap can facilitate the rotational assembly between the sleeving component 17 and the rolling brush 121, and a gap can be formed between the inner end of the first cylindrical brush 121a and the inner end of the second cylindrical brush 121b to form a shaft structure which is beneficial to the sleeving assembly of the sleeving component 17. For example, the first brush 121a and the second brush 121b are connected by a connecting portion 172, and the connecting portion 172 is configured to facilitate the sleeving of the sleeving member 17, such as a shaft structure.

Moreover, after a gap is formed between the inner end of the first cylindrical brush 121a and the inner end of the second cylindrical brush 121b, the sleeving component 17 can also extend into the gap formed between the inner end of the first cylindrical brush 121a and the inner end of the second cylindrical brush 121b, so that the rotating assembly between the sleeving component 17 and the rolling brush 121 is firmer and tighter, and the inner end of the first cylindrical brush 121a and the inner end of the second cylindrical brush 121b can also form a certain supporting effect on the part of the sleeving component 17 extending into the gap, so that the overall assembly is more stable.

It should be noted that, when the first brush 121a and the second brush 121b are placed in a direction of relative assembly, an end of the first brush 121a facing the second brush 121b is an inner end of the first brush 121a, an end of the first brush 121b not facing the second brush 121b is an outer end of the first brush 121a, and for the second brush 121b, an end of the second brush 121b facing the first brush 121a is an inner end of the second brush 121b, and an end of the second brush 121b not facing the first brush 121a is an outer end of the second brush 121 b. Meanwhile, referring to fig. 8 to 11, the inner end of the first brush drum 121a is the right end in the drawing, the outer end of the first brush drum 121a is the left end in the drawing, the inner end of the second brush drum 121b is the left end in the drawing, and the outer end of the second brush drum 121b is the right end in the drawing.

As for the connecting portion 172, the connecting portion 172 may have various structural forms as long as the connecting portion 172 can form a coaxial connection between the first cylindrical brush 121a and the second cylindrical brush 121b, and make the first cylindrical brush 121a and the second cylindrical brush 121b form a rotational assembly with the socket assembly 17 by using the connecting portion 172 at the same time, in one embodiment, the connecting portion 172 may form an axial structure for facilitating the rotational assembly with the socket assembly 17, for example, the connecting portion 172 includes an outer sleeve 172a, and the outer sleeve 172a is disposed at the inner end of the first cylindrical brush 121 a; the connecting portion 172 further includes an inner insertion portion 172b, and the inner insertion portion 172b is disposed at an inner end of the second cylindrical brush 121 b; the inner insertion portion 172b is inserted into the outer sleeve 172a, and the inner ring of the bearing 170 is fitted into the outer sleeve 172 a. The outer sleeve 172a is a cylindrical structure, so that the inner insertion portion 172b can form a coaxial opposite structure with the first cylindrical brush 121a, and after the inner insertion portion 172b is inserted into the outer sleeve 172a, the second cylindrical brush 121b can also form a coaxial opposite structure with the first cylindrical brush 121a, so as to complete the construction of the rolling brush 121.
