The present application is further described below with reference to specific embodiments, and it should be noted that, without conflict, any combination between the embodiments or technical features described below may form a new embodiment.

In the description of the present application, it should be noted that, for the terms of orientation, such as "central", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., it indicates that the orientation and positional relationship shown in the drawings are based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be construed as limiting the specific scope of protection of the present application.

It is noted that the terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

The terms "comprises," "comprising," and "having," and any variations thereof, in the description and claims of this application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Most of the conventional fluid dispensers directly spray cleaning fluid onto the brush roll, and the number of the fluid dispensers is limited, so that the cleaning fluid cannot be completely covered on all surfaces of the brush roll, and a large amount of cleaning fluid is distributed on the surface of the brush roll facing the fluid dispensers, and a small amount of cleaning fluid or even no cleaning fluid is distributed on the surface of the brush roll facing away from the brush roll, i.e. the above-mentioned direct-spraying fluid distribution mode easily causes uneven distribution of the cleaning fluid.

Based on the above problem, this application has designed indirect injection's fluid delivery system to solve the uneven problem of fluid distribution, and the concrete structure is as follows:

as shown in fig. 1 to 10, a preferred embodiment of the present application includes a housing 1, a brush roll 2, and a fluid delivery system 3, the brush roll 2 being rotatably disposed in the housing 1, the fluid delivery system 3 including a fluid distributor 31 and a fluid guide 32 disposed in the housing 1, the fluid guide 32 being disposed on a circumferential side of the brush roll 2 and extending axially along the brush roll 2; the fluid distributor 31 is adapted to spray cleaning fluid which is adapted to contact the fluid guide 32 and flow along the fluid guide 32 towards the brush roll 2. In the present exemplary embodiment, the fluid guide 32 is embodied as an inclined deflector, on which the cleaning fluid can flow onto the brush roller 2 in a dispersed manner under the influence of gravity.

As shown in fig. 5, the brush roller 2 has a horizontal partition line L1 passing through the rotation center thereof, and the fluid guide 32 is located at an upper side of the horizontal partition line L1 in order to allow the cleaning fluid to be entirely flowed to the brush roller 2 by gravity.

As can be seen from fig. 5, the cleaning fluid from the fluid distributor 31 smoothly flows to the fluid guide 32 and then is guided to the brush roller 2 by the fluid guide 32, and the above structure has certain requirements on the fluid flow rate and the fluid shape of the fluid distributor 31 in order to achieve uniform distribution. Further, the cleaning fluid discharged from the fluid distributor 31 is dispersed, and the dispersed cleaning fluid is dispersed to the fluid guide 32 and guided toward the brush roller 2 through the fluid guide 32.

In order to reduce the performance requirements of the fluid distributor 31, the fluid delivery system 3 may also be provided with fluid scattering elements, as shown in fig. 6, in which case the housing 1 is adapted to act as a fluid scattering element, the cleaning fluid is adapted to impact the housing 1 and to be scattered along the housing 1, and the fluid guides 32 are adapted to receive the scattered cleaning fluid and eventually to flow more evenly and dispersedly towards the brush roll 2. In the above configuration, the fluid distributor 31 may be the most common direct flow spray head and maintain the proper water pressure in the fluid delivery system 3.

Of course, as shown in fig. 7, the position of the fluid distributor 31 can be changed to make the cleaning fluid sprayed from the fluid distributor 31 directly impact on the fluid guide 32, and the fluid guide 32 acts as a fluid scattering member, and can also achieve a more uniform and dispersed distribution effect.

Another key design is that the ends of the fluid guides 32 intersect or are tangential to the surface of the brush roll 2, as shown in fig. 5-7, the fluid guides 32 being adapted to block the cleaning fluid from following the rotation of the brush roll 2. In addition, the surface cleaning apparatus further comprises a fluid recovery system 4, the fluid recovery system 4 having a suction inlet 41, the suction inlet 41 being located on the underside of the fluid guide 32. The above-mentioned structure setting mainly has two effects: (1) The fluid guide 32 can also be used as a scraping strip for scraping off sewage and dust on the brush roller 2, so that the cleaner side of the brush roller 2 is in contact with the surface of an object, and the cleaning effect is ensured; (2) The fluid guide piece 32 can also be used as a barrier strip to prevent sewage and dust from being carried out or thrown away by the brush roller 2, and the scraped sewage and dust can be timely recovered by the fluid recovery system 4 at the rear part, so that the sewage and dust are prevented from splashing randomly in the shell 1, and the cleaning and the maintenance are convenient. In contrast, as shown in fig. 8, the end of the fluid guide 32 is spaced apart from the surface of the brush roller 2, and the fluid guide 32 has only a flow guiding function.

Preferably, as shown in fig. 5, the brush roller 2 is adapted to rotate clockwise, the suction port 41 is located at the rear side of the brush roller 2, the brush roller 2 has a vertical partition line L2 passing through the center of rotation thereof, and the fluid guide 32 is located at the rear side of the vertical partition line L2; the fluid guide 32 is adapted to block the cleaning fluid and the dust at the rear side of the brush roller 2 and enter the fluid recovery system 4 through the suction port 41.

As shown in fig. 2, as a conventional arrangement, the inside of the housing 1 is divided into a dry area 1a and a wet area 1b, a fluid distributor 31 is disposed between the dry area 1a and the wet area 1b and adapted to spray cleaning fluid toward the wet area 1b, and the brush roller 2 and the fluid guide 32 are both disposed in the wet area 1 b.

As shown in fig. 3 and 4, in order to facilitate the removal of the washing brush roller 2, the housing 1 includes a main housing 11 and a sub-housing 12, the sub-housing 12 is detachably provided on the main housing 11, and the sub-housing 12 is located above the wet area 1 b. As shown in fig. 1 to 8, the fluid guides 32 are provided on the sub-housing 12. As shown in fig. 5, the fluid guide 32 is disposed on the sub-housing 12, so that a contaminated area a is formed in front of the intersection point of the fluid guide 32 and the brush roller 2, and thus, a contaminated area a is concentrated in a place where contamination is generated during cleaning or self-cleaning, and the main housing 11 on the rear side is kept substantially clean, so that only the sub-housing 12 needs to be disassembled for cleaning, and maintenance of the floor washing machine is facilitated.

In view of manufacturing costs, the fluid guide 32 and the sub-housing 12 are preferably integrally injection molded. Of course, the fluid guide 32 may be provided on the main housing 11, as shown in fig. 9 and 10, which illustrate a configuration in which the fluid guide 32 is provided on the main housing 11, wherein the fluid guide 32 has a gap with the surface of the brush roll 2 in fig. 9, and the fluid guide 32 intersects the surface of the brush roll 2 in fig. 10.

It is contemplated that the cleaning fluid of the present embodiment includes, but is not limited to, clear water, cleaning liquids, cleaning foams, high pressure gas.

It should be noted that the structures and operating principles of the fluid supply tank, the fluid supply pipe, etc. of the fluid delivery system 3 are the prior art, and therefore, they are not described in detail in this embodiment, but this does not prevent them from becoming the implicit technical features of this application.

It should be noted that the fluid delivery system 3 of the present embodiment may also be applied to a lubrication system, a heat dissipation system, a paint spraying system, etc., and the corresponding fluids are respectively a lubricant, a cooling liquid and paint, which can also achieve a wider and more uniform application effect.

The foregoing has described the general principles, essential features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and such changes and modifications are intended to be within the scope of the application as claimed.
