Detailed Description

Referring to fig. 1, a surface cleaning floor brush 100 according to an embodiment of the present application is illustrated, which comprises a brush head portion 1 and a pole portion 2. The lower part of the vertical rod part 2 is rotatably connected to the brush head part 1, and the vertical rod part 2 has an upright stop position and a backward inclined use position. For purposes of describing the invention in connection with the drawings, the terms "upper", "lower", "right", "left", "rear", "front", "vertical", "horizontal", "inner", "outer" and derivatives thereof shall relate to the invention as shown in FIG. 1. From the user's perspective, the user stands on the rear side of the surface cleaning floor brush 100 while using the surface cleaning floor brush 100.

As shown in fig. 2-4, the brush head portion 1 is adapted to be moved over a surface to be cleaned, in particular a floor surface; it comprises a housing 11 having a front side 111, a rear side 112, a left side 113, a right side 114, an upper side 115 and a lower side 116. The housing 11 defines a suction duct 12, the suction duct 12 having an opening 13 (shown schematically in fig. 2 and 3) on a lower side 116 of the housing 11. The suction duct 12 leads to a suction motor (not shown) located in the surface cleaning brush or elsewhere in the vacuum cleaner. The suction duct 12 is formed at a front portion thereof by a hose 121, at a middle portion thereof by an inner space 122 defined by an inner wall of the housing 11, and at a rear portion thereof by a hose 123. The suction duct 12 receives and guides the dirty liquid mixed fluid sucked by suction, and the opening 13 is located at the intersection of the suction duct 12 and the lower side 116 of the housing 11. The housing 11 and its components may have other shapes and configurations in other embodiments. A cleaning liquid discharge passage (not shown) for discharging cleaning liquid, such as water stored in a cleaning liquid tank 22 mentioned below, an aqueous solution containing a detergent and/or a bactericide, or the like, to the outside to wet the surface to be cleaned is provided in the housing 11. The cleaning liquid discharge channel has drip openings 17 on the lower side 116 of the housing 11, by means of which drip openings 17 the cleaning liquid can be continuously supplied to the cleaning tool or the surface to be cleaned on the lower side 116 of the housing 11.

A pair of large moving wheels 118 are provided on the rear side 112 of the housing 11, the pair of moving wheels 118 being capable of driving the brush head 10 across the surface to be cleaned. The lower side 116 of the housing 11 is also provided with a pair of support wheels 117 at an intermediate position. A pair of support wheels 117 can facilitate better movement of the housing 11 by the user.

A flexible suction nozzle 14 is also provided on the lower side 116 of the surface cleaning brush 100. In this example, a flexible suction nozzle 14 is arranged at the opening 13. The flexible suction nozzle 14 includes: a front flexible scraping lip strip 141 and a rear flexible scraping lip strip 142 which are arranged in a front-rear opposite mode. The front flexible scraping lip strip 141 and the rear flexible scraping lip strip 142 both extend in the left-right direction and are arranged at the edges of the front side and the rear side of the opening 13, and a dirty liquid suction channel 143 communicated with the suction channel 12 is formed between the front flexible scraping lip strip 141 and the rear flexible scraping lip strip 142.

In this example, the front flexible lip strip 141 and the rear flexible lip strip 142 are provided with

protrusions

1411 and 1421 on the sides facing away from the dirty liquid suction path 143, respectively. The opening 13 is provided with a plurality of ribs 131 dividing the opening 13 into a plurality of small openings in the left and right direction. The ribs 131 also serve to reinforce the strength at the opening 13.

As shown in fig. 5, when the brush head portion 1 is pushed forward to move forward along the surface to be cleaned, the protrusion 1411 of the front flexible lip strip 141 lifts the front flexible lip strip 141, so that a front gap 144 communicating with the dirty liquid suction passage 143 is left between the front flexible lip strip 141 and the surface to be cleaned, and fine dust and dirty liquid in front of the flexible suction nozzle 14 can be continuously sucked into the dirty liquid suction passage 143 from the front gap 44; at this time, the rear flexible lip scraping strip 142 is tightly attached to the surface to be cleaned, and the liquid drops behind the rear flexible lip scraping strip 142 are isolated from the suction nozzle 14.

As shown in fig. 6, when the brush head portion 1 is pulled backward so as to move backward along the surface to be cleaned, the protrusion 1421 of the rear flexible lip scraping bar 142 lifts up the rear flexible lip scraping bar 142, so that a rear slit 145 communicating with the stain liquid suction passage 143 is formed between the rear flexible lip scraping bar 141 and the surface to be cleaned; at this time, the front flexible lip strip 141 is tightly attached to the surface to be cleaned, and the front area of the front flexible lip strip 141 and the dirt-breaking liquid suction passage 143 are separated.

As further shown in fig. 3 and 4, the lower side portion 116 of the housing 11 has a recess 1161 at the rear side of the flexible suction nozzle 14, the recess 1161 is provided with the base plate 19, the front portion of the base plate 19 is integrated with the brush 15, and the brush 15 is a plate brush with a plurality of rows of bristles 151. A plurality of drip ports 17 are integrated at a central position of the substrate 19, and the brush 15 and the drip ports 17 are disposed in close proximity. A flexible wiping strip 18 is mounted on the rear portion of the substrate 19, the flexible wiping strip 18 in this example extends in the left-right direction, and the flexible wiping strip 18 can achieve wiping of the surface to be cleaned on the one hand by contact with the surface to be cleaned and also can effectively prevent the cleaning liquid dropping from the dropping port 17 from flowing to the rear portion of the flexible wiping strip 18 beyond the flexible wiping strip 18 on the other hand. The rear side surface of the flexible wiping strip 18 is provided with a plurality of concave pits 181. These dimples 181 increase the flexibility of the flexible wiper strip 18 and also improve the wiping properties of the flexible wiper strip 18.

In order to enable the floor brush 100 of the present example to accommodate a wide variety of surfaces to be cleaned; in this example, the base plate 19 is rotatably mounted in the recess 1161 of the housing 11 back and forth, i.e., about an axis extending in the left-right direction. By means of the oscillating substrate 19, the brush 15 obtains a first state with contact with the surface to be cleaned and a second state away from the surface to be cleaned. By the arrangement, a user can conveniently perform cleaning work on the surfaces to be cleaned made of different materials; as in the first state, the user can simultaneously contact the surface to be cleaned by means of the flexible suction nozzle 14, the brush 15 and the flexible wiper strip 18 to clean the surface to be cleaned; whereas in the second state the brush 15 is away from the surface to be cleaned, the user can only clean the surface to be cleaned by means of the flexible suction nozzle 14 and the flexible wiper strip 18. However, in either condition, the flexible wiping strip 18 is always in close proximity to the surface to be cleaned.

Continuing with fig. 1, the pole part 2 comprises a pole 20, the lower part of which is pivotally connected to the housing 11, the pole 20 being provided with an interface 21 for detachable connection to a vacuum cleaner. A removable cleaning liquid tank 22 and a waste tank 23 are also arranged on the upright 20. The cleaning liquid tank 22 and the sewage tank 23 are arranged one above the other and are located on the front side of the upright 20. After the dirty liquid tank 23 is mounted to the upright 20, the dirty liquid tank 23 will be in communication with the suction pipe 12 and the interface 21 at the same time, so that the suction pipe 12, the dirty liquid tank 23 and the interface 21 are in fluid communication in sequence. After the cleaning liquid tank 22 is mounted on the upright 20, the cleaning liquid tank 22 is connected to the cleaning liquid outlet channel, and the cleaning liquid tank 22 sends the cleaning liquid contained therein to the drip port 17 via the fluid delivery channel. In order to allow the user to autonomously control whether the fluid delivery channel delivers the liquid, a mechanical valve (not shown) is provided in the cleaning liquid delivery channel, which mechanical valve can be actuated by an external operating button (not shown).

As shown in fig. 7, when the brush head portion 1 is pushed forward to move, cleaning liquid drops from the liquid drop port 17 to the surface to be cleaned, and is separated from the surface to be cleaned by the flexible liquid scraping strip 18, the flexible liquid scraping strip 18 pushes and scrapes the liquid drops falling on the surface to be cleaned forward and is always restrained in front of the flexible liquid scraping strip 18, and the flexible liquid scraping strip 18 rubs against the surface to be cleaned to form a first cleaning of the surface to be cleaned; in this process, since the liquid droplets are confined in front of the flexible wiper strip 18, it can be ensured that the surface to be cleaned behind the flexible wiper strip 18 is free from residual liquid droplets. Any fine debris or droplets in front of the flexible suction nozzle 14 will be sucked up by the flexible suction nozzle 14 and fed through the opening 13 into the suction channel 12.

As shown in fig. 8, at the next moment, when the user pulls the brush head part 1 backwards to move, the brush 15 mixes the liquid drops and rubs with the surface to be cleaned, so as to clean the surface to be cleaned for the second time, the liquid drops are not blocked by the brush 15, the liquid drops are collected to the flexible suction nozzle 14, the flexible suction nozzle 14 absorbs the liquid drops, the liquid drops are sent to the suction channel 12 through the opening 13, and then the liquid drops are sent to the sewage tank 23; the step can suck up all the liquid drops on the surface to be cleaned, thereby realizing no water stain on the surface to be cleaned. During this movement, both the front flexible scraping lip strip 141 and the rear flexible scraping lip strip 142 of the flexible suction nozzle 14 rub against the surface to be cleaned, forming a third cleaning of the surface to be cleaned.

Of course, if the surface to be cleaned is not suitable for brushing with the brush 15, the substrate 19 may be rotated to switch the brush 15 to a second position away from the surface to be cleaned, and subsequent operation is similar to that described above and will not be described in further detail herein.

Figure 9 shows an example of a vacuum cleaner comprising a surface cleaning brush 100 and a handheld vacuum apparatus 200. The floor brush 100 has the above-described floor brush structure of fig. 1. The handheld vacuum device 200 in this example can be used alone as a handheld vacuum cleaner. The inlet end 201 of the hand-held vacuum device 200 is coupled to the interface 21, and the negative pressure suction force generated by the hand-held vacuum device 200 can extend to the interface 21 and gradually extend downward until reaching the flexible suction nozzle 14.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
