At present, cleaning device can include the host computer and the scrubbing brush structure of being connected with the host computer, and the host computer passes through connecting rod and scrubbing brush structural connection to the rotatable setting of scrubbing brush structure relatively. The floor brush structure is used to clean a surface to be cleaned (e.g., a floor). In particular, the floor brush arrangement may include cleaning elements for wet mopping, which cleaning elements contact the floor surface during operation. The cleaning apparatus may wet the cleaning members of the floor brush structure with the water tank and then perform a wet scrubbing operation with the cleaning members. In particular, the cleaning elements may comprise a roller brush rotating about a horizontal axis of rotation, or may comprise different forms of mops or the like which reciprocate relative to the floor.

However, before cleaning device wet-mopping, in order to avoid the particles on the ground to be drawn into the cleaning piece, the structure of the floor brush or the ground is abraded, the user needs to clean dry garbage such as the particles on the ground firstly, so that the cleaning operation on the ground is time-consuming and labor-consuming, and the cleaning efficiency is influenced.

Therefore, the application provides a floor brush structure and a cleaning device, which are provided with dry suction rolling brushes and floor mopping rolling brushes which are arranged at intervals; the dry suction rolling brush and the floor mopping rolling brush are arranged in parallel, and the floor mopping rolling brush can be soaked by the cleaning liquid; when the scrubbing brush structure cleans, dry suction rolling brush can clean dry rubbish on the ground in front of the traveling direction of the scrubbing brush structure, wet-mopping operation is completed after mopping the scrubbing brush, and mutual interference between the dry suction rolling brush and the mopping rolling brush is small. Like this user when carrying out normal clean operation, the scrubbing brush structure can accomplish simultaneously and clean and wet the operation of dragging, links up comparatively closely between two operations, has reduced user's work load, and clean efficiency is higher, and clean effect is better.

The structure and various possible implementations of the floor brush structure and the cleaning device provided by the present application will be described in detail below with reference to the specific embodiments.

Fig. 1 is a schematic structural diagram of a floor brush structure provided in an embodiment of the present application. Fig. 2 is a schematic structural view of the floor brush structure of fig. 1 when the roll brush assembly is separated from the housing. Fig. 3 is an exploded view of the structure of the floor brush of fig. 1. As shown in fig. 1 to 3, the present application provides a floor brush structure applied to a cleaning device. Wherein, the cleaning device can be a dust collector, a floor mopping machine and other household cleaning devices.

The floor brush structure comprises a shell 110, a rolling brush component 120, a water spraying component 130, a sewage recovery component 140 and the like, wherein the rolling brush component 120, the water spraying component 130 and the sewage recovery component 140 are all arranged on the shell 110. And the housing 110 may be provided with a coupling structure for coupling with other parts of the cleaning apparatus, such as a main unit.

Specifically, in order to perform a cleaning operation on the ground, the rolling brush assembly 120 includes a dry suction rolling brush 121 and a floor mopping rolling brush 122 which are arranged at an interval and are parallel to each other, the dry suction rolling brush 121 and the floor mopping rolling brush 122 are both rotatably arranged in the housing 110 and partially exposed out of the bottom of the housing 110, and the dry suction rolling brush 121 and the floor mopping rolling brush 122 are respectively located at two ends of the housing 110 along the traveling direction of the floor brush structure. Wherein, the surface of the dry suction rolling brush 121 is dry, and is mainly used for cleaning particles, dust or other dry garbage on the ground; the floor-mopping roller 122 has a relatively wet cleaning surface, and the floor can be wet-mopped by rolling the floor-mopping roller 122 relative to the floor, i.e., mopping the floor like a mop.

The dry suction brush 121 and the floor brush 122 may have the same or different structures. For example, the dry suction brush 121 and the floor brush 122 may have the same size and the same surface material. Optionally, to achieve wet mopping of the ground, the circumferential surface of the mopping roller brush 122 is a flexible surface. At this time, a layer of soft material, such as wool, may be attached to the surface of the floor-mopping roller brush 122.

When the floor mopping roller 122 rotates relative to the housing 110 to perform a floor mopping operation, the surface of the floor mopping roller 122 needs to be soaked with a liquid, so that the floor mopping structure is provided with the water spraying assembly 130, the water spraying assembly 130 is arranged on the housing 110, the water spraying assembly 130 is provided with the water spraying piece 131, the water spraying piece 131 faces the floor mopping roller 122 (i.e. the spraying direction of the water spraying piece 131 faces the floor mopping roller 122), and the cleaning liquid can be sprayed out of the floor mopping roller 122, so that the floor mopping roller 122 is wetted. And the sewage recovery unit 140 is in contact with the floor-mopping roller brush 122, so that the sewage contained in the floor-mopping roller brush 122 is guided out and collected by pressing or the like.

Since the dry suction brush 121 and the floor scrubbing brush 122 are arranged in parallel with each other, the dry suction brush 121 and the floor scrubbing brush 122 can both rotate in the traveling direction of the floor scrubbing structure when performing cleaning operation, thereby respectively completing respective dry garbage cleaning and wet scrubbing operations when the floor scrubbing structure travels. Meanwhile, the dry suction brush 121 and the floor brush 122 are respectively located at opposite ends of the housing 110 in the traveling direction of the floor brush structure, so that the dry suction brush 121 and the floor brush 122 have less interference with each other in operation, and dry garbage cleaning and wet mopping operations can be performed relatively independently.

Like this, the user only need control the scrubbing brush structure when clean and advance, can be at the relative ground in-process of advancing of scrubbing brush structure, successively accomplish the dry rubbish clearance and the wet operation of dragging on ground, and do not need additionally to carry out the clearance of dry rubbish alone once more or wet the operation of dragging, the cleaning operation of scrubbing brush structure is comparatively simple and convenient, has effectively reduced user's intensity of labour, simultaneously because dry rubbish clearance and wet work between dragging are relatively independent, clean effect is also better.

It should be noted that, whether the water spraying assembly 130 or the sewage recovering assembly 140 works, it directly acts on the rolling mopping brush 122, for example, the cleaning liquid is directly sprayed onto the surface of the rolling mopping brush 122 through the water spraying member 131, or the sewage is directly collected by pressing and contacting the rolling mopping brush 122, so that compared with the prior art in which the cleaning liquid is sprayed onto the ground and then absorbed by the rolling mopping brush 122, or the sewage is recovered from the ground dragged by the rolling mopping brush 122, the water spraying and sewage cleaning process for the rolling mopping brush 122 directly acts on the surface of the rolling mopping brush 122, and the intermediate link is omitted, so that the cleaning and wetting effects for the rolling mopping brush 122 are better.

In order to reduce particles or other debris on the floor surface that may interfere with the wet mopping operation, in an alternative embodiment, the dry suction roller brush 121 is located forward (i.e. + X direction in fig. 2) of the floor mopping roller brush 122 in the direction of travel of the floor brush structure, i.e. the dry suction roller brush 121 and the floor mopping roller brush 122 are arranged in sequence from front to back in the direction of travel of the floor brush structure. It should be noted that the floor brush structure may be a straight path or a curved path during travel, and it should not be understood that only a straight path exists, as long as the floor brush structure moves substantially along the forward region in the direction of travel.

It will be appreciated that when a user cleans the floor surface using the cleaning apparatus, the user will drive the floor brush structure in a direction (e.g., + X direction) generally along the length of the floor brush structure to complete the cleaning operation on the floor surface during the travel. The ground brush structure generally has a one-way direction, for example, the ground brush structure travels from the rear end to the front end in the length direction thereof, i.e. the + X direction in fig. 2. At this time, the dry suction rolling brush 121 cleans dry garbage such as particles on the ground by a front-back arrangement of the dry suction rolling brush 121 and the floor mopping rolling brush 122 along the traveling direction (that is, the floor mopping rolling brush 122 is located at one side of the dry suction rolling brush 121 along the-X direction), and then the floor mopping rolling brush 122 performs wet mopping operation on the cleaned ground. Thus, the floor brush 122 will not stick particles or other dry debris when wet, the surface of the floor brush 122 is relatively clean, and the floor or the body of the floor brush 122 will not be scratched or worn.

Since the dry suction drum brush 121 and the floor brush 122 are spaced apart from each other by a relatively long distance, other structural or functional components may be disposed between the dry suction drum brush 121 and the floor brush 122. As an alternative structure, the water spray 131 is positioned between the dry suction drum brush 121 and the floor-mopping drum brush 122, and the water spray 131 has a water spray opening facing the floor-mopping drum brush 122.

At this time, by using the space between the dry suction drum brush 121 and the floor brush 122, the water spray member 131 and the like can be installed, and the water spray member 131 can spray the water directly toward the floor brush 122, thereby facilitating the installation and work of the water spray member 131 and the like, and at the same time, facilitating the counterweight of the floor brush structure itself.

In an alternative mode, the axes of rotation of the dry suction brush 121 and the floor brush 122 are at the same level, and the outer diameters of the dry suction brush 121 and the floor brush 122 are identical. Thus, the dry-suction rolling brush 121 and the floor-mopping rolling brush 122 rotate relatively uniformly during work, which is beneficial to keeping the structure of the floor brush stable during work and maintaining the horizontal posture.

Alternatively, the dry suction brush 121 and the floor brush 122 may have the same rotation direction when performing the cleaning operation. At this time, the dry suction drum brush 121 may be rotated in a clockwise direction simultaneously with the floor-mopping drum brush 122, or in a counterclockwise direction simultaneously.

Thus, the dry-suction rolling brush 121 and the mopping rolling brush 122 rotate along the same rotating direction when cleaning the ground, so that the structure of the floor brush can be smooth when moving forward, and the cleaning efficiency is improved.

Various possible configurations and embodiments of the water spray assembly are further described below.

FIG. 4 is a schematic structural view of a water spray assembly in a floor brush structure according to an embodiment of the present disclosure. As shown in fig. 1 to 4, in an alternative embodiment, the water spraying member 131 of the water spraying assembly extends along the axial direction (i.e. the Y direction in the drawing) of the floor brush 122, and the water spraying member 131 is provided with a plurality of water spraying openings 1311, and the plurality of water spraying openings 1311 are arranged at intervals along the axial direction of the floor brush 122.

At this time, the lengthwise direction of the water spray 131 is along the axial direction of the floor-mopping rolling brush 122, that is, the lengthwise direction thereof; meanwhile, two or more water spray nozzles 1311 are provided on the water spray member 131, so that the plurality of water spray nozzles 1311 on the water spray member 131 can spray cleaning liquid to different positions in the axial direction of the floor-mopping roller brush 122, respectively, and the water spray coverage of the water spray member 131 is large.

When the water spraying assembly sprays water, the floor-mopping rolling brush 122 can be kept in a rotating state, and therefore, the water spray nozzles 1311 only need to face the same radial position of the floor-mopping rolling brush 122, and different sides of the floor-mopping rolling brush 122 in the circumferential direction can respectively face the water spray nozzles 1311 through the rotation of the floor-mopping rolling brush 122, so that the entire circumferential surface of the floor-mopping rolling brush 122 can be wetted.

As an alternative water spraying structure, a water blocking bar 1312 extending in an axial direction of the rolling brush 122 may be provided at a side of the water spraying member 131 facing the rolling brush 122, and the water blocking bar 1312 is located below the water spraying opening 1311. The water bar 1312 receives the scattered droplets from the water jet 1311 to reduce interference with other structures during operation of the water jet assembly 130.

Wherein, the water spray assembly 130 can be communicated with the outside, so as to provide cleaning liquid for the water spray part 131 by using external equipment, or a liquid storage component can be arranged in the water spray assembly 130, and the liquid storage component is used for providing liquid for the water spray part 131. Specifically, as an alternative, the water spray assembly 130 further includes a clean water tank 132, and the clean water tank 132 communicates with the water spray 131 to supply water to the water spray 131, as shown in fig. 1 to 3.

In particular, the fresh water tank 132 may be provided on the floor brush structure, for example, on the housing 110 of the floor brush structure. The water purifying tank 132 may be detachably connected to the floor brush structure, or may be integrally formed with the housing 110 of the floor brush structure.

In a specific implementation, in order to allow the cleaning liquid to be normally sprayed, the water spray assembly 130 may further include a driving pump 133, and the driving pump 133 is connected between the water spray member 131 and the clean water tank 132 for spraying the cleaning liquid in the clean water tank 132 through the water spray member 131.

The clean water tank 132 may be provided at other positions and locations of the cleaning device. In another alternative, the clean water tank 132 is provided on the main body of the cleaning device, and in particular, may be provided on a handle portion of the main body, or the like. In this case, the clean water tank 132 may be detachably connected to the main body of the cleaning apparatus, or may be integrally formed with the main body.

It will be readily appreciated by those skilled in the art that, in addition to the above-described arrangement of connection between the spout 131 and the fresh water tank 132, the drive pump 133 may be connected directly to the fresh water tank 132 to cause air to displace the cleaning liquid in the fresh water tank 132 to the spout 131 by injecting a stream of air into the fresh water tank 132. It should be noted that, at this time, the clean water tank 132 should have a closed cavity to ensure the normal operation of the driving pump 133.

When the floor brush 122 performs a cleaning operation, dirt on the floor adheres to the floor brush 122 along with the cleaning liquid, thereby forming dirty water. In order for the sewage recovery assembly to squeeze out and clean the sewage contained in the floor-mopping roller brush 122, thereby allowing the floor brush structure to perform a continuous cleaning operation, the sewage recovery assembly 140 has a wiper element in contact with the floor-mopping roller brush 122 and a receiving element for receiving the sewage. FIG. 5 is a schematic cross-sectional view of a water spray assembly and a wastewater recovery assembly in a floor brush structure according to an embodiment of the present disclosure. Fig. 6 is a partially enlarged schematic view at a in fig. 5. As shown in fig. 3 to 6, the sewage recycling assembly 140 in the floor brush structure specifically includes a scraping strip 141 and a water collecting piece 142, the scraping strip 141 and the water collecting piece 142 are both disposed on the housing 110, the scraping strip 141 is located above the water collecting piece 142 and is in interference fit with the floor rolling brush 122, and the water collecting piece 142 is used for collecting the sewage scraped by the floor rolling brush 122. Like this through scraping strip 141 and the recovery of catchment piece 142, in the course of the work of scrubbing brush structure, the sewage on the round brush 122 of mopping is just in order to clear up in real time, and the clean surface of round brush 122 of mopping maintains comparatively clean state all the time, has avoided the sewage of round brush 122 of mopping to cause secondary pollution to ground.

Furthermore, a ground scraping strip 111 may be disposed below the water collecting member 142.

Since the outer circumferential surface of the floor-mopping roller 122 is generally made of a flexible material, the scraping strip 141 abuts against the surface of the floor-mopping roller 122 and scrapes off the sewage on the floor-mopping roller 122 without hindering the normal rotation of the floor-mopping roller 122.

Wherein, the scraping strip 141 and the water collecting piece 142 are both positioned between the dry suction rolling brush 121 and the mopping rolling brush 122, so that the main body of the sewage recovery component 140 and the main body of the water spray component 130 are both positioned at the middle position of the scrubbing brush structure, which is convenient for the counterweight of the scrubbing brush structure, and makes the structure of the scrubbing brush structure more compact.

Wherein, the extending direction of the scraping bar 141 may be consistent with the axial direction of the rolling mopping brush 122, and the length of the scraping bar 141 in the extending direction may be greater than or equal to the axial length of the rolling mopping brush 122, so that the scraping bar 141 can scrape off the sewage on the whole rolling mopping brush 122. In a specific implementation, the wiper strip 141 may be a metal wiper strip 141, such that the wiper strip 141 has good wear resistance.

In order to maintain the contact between the bar 141 and the surface of the floor brush 122, optionally, the bar 141 includes a support 1411 and an inclined portion 1412 connected to one side of the support 1411, the support 1411 is fixed with respect to the housing 110, the inclined portion 1412 is inclined toward the floor brush 122, and an end of the inclined portion 1412 contacts the floor brush 122. Thus, an angle is formed between the inclined portion 1412 of the scraper 141 and the floor brush 122, and the side of the inclined portion 1412 is contacted with the outer circumferential surface of the floor brush 122 when the floor brush 122 rotates, so that the scraper 141 is not easily broken by the force of the floor brush 122.

Alternatively, the height of the side of the inclined portion 1412 facing the floor roll brush 122 is greater than the height of the side of the inclined portion 1412 facing away from the floor roll brush 122. By arranging the inclined portion 1412 to be inclined with respect to the vertical direction, the dirty water on the floor wiping roller 122 scraped off by the scraper 141 flows toward the support 1411 along the lower surface of the inclined portion 1412, and is collected and dropped at the joint of the inclined portion 1412 and the support 1411, and enters the range where the water collecting member 142 can receive the dirty water.

In some embodiments, the wiper strip 141 is located below the water jet 131. Therefore, the sewage recovery assembly 140 and the water spray assembly 130 can be arranged at a close position, so that the floor brush structure has a compact overall structure and size.

Alternatively, the rotation direction of the floor brush 122 is directed from the side near the wiper strip 141 to the side near the water spray 131. Thus, the scraping bar 141 can scrape the dirty water of the dirty part of the floor-mopping roller brush 122 before the dirty part rotates to face the water spray 131; and the part after scraping the sewage is sprayed with the cleaning liquid again. Thereby allowing a tighter engagement between the water spray of the mopping roller brush 122 and the sewage recovery operation.

The water collection member 142 can also have a variety of different forms and configurations. In an alternative form, the water collection member 142 is a water collection channel, an opening 1421 of which faces the floor brush 122.

Since the opening 1421 of the water collecting groove faces the floor-mopping roll brush 122. In the process of rotating the rolling mopping brush 122, the sewage enters the water collecting tank, and the water collecting tank generally has a tank bottom, so that a cavity capable of storing the liquid is formed in the water collecting tank, and the sewage on the rolling mopping brush 122 is temporarily stored in the water collecting tank.

To improve the efficiency of collecting the contaminated water on the floor-scrubbing roller brush 122, a water collection sump is generally disposed at a lower portion of the floor-scrubbing roller brush 122, wherein the water collection sump may be located at one side of the floor-scrubbing roller brush 122 and below the rotational axis of the floor-scrubbing roller brush 122, for example. The sewage thrown off the floor-mopping rolling brush 122 or scraped off by the scraping strips 141 can be collected into the water collecting tank under the action of gravity.

Optionally, the water collecting tank extends in the same direction as the axis of the rolling mopping brush 122, and the water collecting tank extends at least to both ends of the rolling mopping brush 122. Thus, the edge of the water collecting groove can be flush with the end of the rolling mopping brush 122, or extend to the outside of the end of the rolling mopping brush 122, and at this time, the whole rolling mopping brush 122 is located in the range covered by the notch of the water collecting groove, so that the water collecting groove has a better collecting effect.
