[0029] BRIEF DESCRIPTION OF DRAWINGS DETAILED DESCRIPTION

[0030] The following description is presented to enable any person skilled in the art to practice the application as claimed. The embodiments disclosed in the following description and claims are only exemplary and are not intended to exhaustively list all possible variations of the application. Those skilled in the art will be able to provide other variations that are encompassed by the present application, without departing from the spirit and scope of the application, as defined by the claims.

[0031] Those skilled in the art should understand that in the disclosure of the present application, the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like are based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore the above terms cannot be understood as a limitation of the present application.

[0032] As shown in Figures 1 to 8 , the present disclosure proposes a dirt collecting floor brush, which comprises a shell 1 provided with a rolling brush cavity, a rolling brush 2 arranged in the rolling brush cavity, and a dirt collecting box 3 comprising a box body 24 and a cover 16 covering the box body 24. The shell 1 is provided with a containing cavity 4 at the rear side of the rolling brush cavity. The containing cavity 4 comprises a first opening 5 and a second opening 6. The first opening 5 is located on the upper side surface of the shell 1. The dirt collecting box 3 is detachably installed in the containing cavity 4 in the up-down direction through the first opening 5. The second opening 6 is located on one side of the rolling brush cavity and is arranged in communication with the front and rear of the rolling brush cavity. When the dirt collecting box 3 is installed in the containing cavity 4, the dirty input port of the dirt collecting box 3 is in butt joint with the second opening 6, and the dirty input port is in communication with the front and rear of the rolling brush cavity through the second opening 6. When the rolling brush 2 is working, the dirt is transported to the dirt collecting bin of the dirt collecting box 3 through the second opening 6 and the dirty input port. When it is necessary to pour out the dirt, the dirt collecting box 3 is detached from the containing cavity 4 and the dirty is poured out through the dirty input port.

[0033] In some embodiments, in combination with Figure 3 , 4 , 7, the dirt collecting box 3 is arranged as a plane on one side of the dirty input port. Correspondingly, the side of the containing cavity 4 where the second opening 6 is arranged is arranged as a plane to cooperate with the front and rear of the dirt collecting box 3. Preferably, as shown in Figure 3 , the plane is arranged as a vertical plane, which is beneficial to the straight up and down disassembly of the dirt collecting box 3. For example, it can also be an inclined plane. Any plane that can be disassembled in the up-down direction can be applied to the present disclosure.

[0034] In some embodiments, as shown in Figure 3 , 4 , 5, the dirty input port comprises a liquid inlet 7 and a solid inlet 8. The liquid inlet 7 and the solid inlet 8 are arranged in the axial direction of the rolling brush 2, and the liquid inlet 7 and the solid inlet 8 are arranged in parallel in the up-down direction.

[0035] As shown in Figure 3 , 6 , the second opening 6 comprises a liquid butt joint port 9 located on the upper side and a solid butt joint port 10 located on the lower side.

[0036] AsFigure 3 , 6 As shown, a scraper 11 is provided on one side of the roller brush cavity at the liquid interface 9. The scraper 11 acts on the rotating roller brush 2 to squeeze out the liquid on the roller brush 2. The squeezed liquid is collected into the sludge collection box 3 through the liquid interface 9 and the liquid inlet 7. Note that the squeezed liquid is not pure liquid; it may contain solids. It is also possible that solids on the roller brush 2 are scraped off during the squeezing process and mixed with the liquid, flowing into the sludge collection box 3.

[0037] like Figure 3 , 6 As shown, the solid interface 10 has comb teeth 12 on one side of the roller brush cavity. The comb teeth 12 act on the rotating roller brush 2 to scrape off the dirt on the roller brush 2. The scraped dirt is collected into the dirt collection box 3 through the solid interface 10 and the solid inlet 8. Note that the comb teeth 12 can be a plate or something else. Figure 6 The roller brush 2 is composed of multiple triangular teeth arranged sequentially along its axial direction, which allows for better scraping of dirt. During the scraping process, some liquid is also scraped into the collection box 3 due to the pressure applied.

[0038] In some embodiments, such as Figure 3 As shown, the sludge collection box 3 includes a first sludge collection chamber 13 and a second sludge collection chamber 14 that are separated from each other. The first sludge collection chamber 13 is used to collect dirt collected from the liquid interface 9 and the liquid inlet 7, and the second sludge collection chamber 14 is used to collect dirt collected from the solid interface 10 and the solid inlet 8. This better distinguishes the types of dirt, which is beneficial for cleaning the roller brush 2, while also performing solid-liquid separation and collection.

[0039] Furthermore, such as Figure 3 As shown, the second dirt collection chamber 14 is located behind the solid interface 10 and has a solid inlet 8. When the dirt collection box 3 is removed from the receiving cavity 4, the solid inlet 8 can be exposed for emptying dirt. The first dirt collection chamber 13 is located behind the second dirt collection chamber 14, and a connecting channel 15 is provided on the upper side of the second dirt collection chamber 14. The front end of the connecting channel 15 serves as a liquid inlet 7 to connect to the rear end of the liquid interface 9, and the rear end of the connecting channel 15 is connected to the first dirt collection chamber 13. In this way, on the one hand, the front and rear positions of the first dirt collection chamber 13 and the second dirt collection chamber 14 and the arrangement of the connecting channel 15 help to reduce the height of the dirt collection box 3, thereby helping to reduce the height of the entire floor brush. On the other hand, the second dirt collection chamber 14 is closer to the side of the roller brush cavity, which is also closer to the side of the roller brush 2, thus helping to shorten the front and rear length of the solid interface 10. The dirt scraped off by the comb teeth 12 can directly reach the second dirt collection chamber 14, which is more efficient. This makes the present invention capable of collecting a large amount of solid dirt in a short time, improving the cleaning ability of the surface being cleaned.

[0040] In some embodiments, such asFigure 3 As shown, in order to collect solid dirt more quickly, the solid interface 10 and the solid inlet 8 are both set to be larger, and the solid inlet 8 is set to be larger to facilitate the pouring of dirt.

[0041] In some embodiments, as shown, Figure 3 As shown, the connecting channel 15 is set to be higher in front and lower in back, which can better collect liquid dirt and facilitate the reduction of backflow.

[0042] In some embodiments, as shown, Figure 3 As shown, the height of the highest liquid level of the first dirt collection bin 13 is set to be lower than the height of the front side of the connecting channel 15, and / or the height of the highest liquid level of the first dirt collection bin 13 is set to be lower than the height of the front lower edge 19 of the liquid interface 9. This can better collect liquid dirt and facilitate the reduction of backflow.

[0043] In some embodiments, as shown, Figure 3 As shown, when the dirt collection box 3 is loaded into the accommodating cavity 4, the lower edge of the front end of the connecting channel 15 is lower than the lower edge of the rear end of the liquid interface 9, so that a step 22 is formed by the height difference, thereby ensuring that the lower edge of the front end of the connecting channel 15 is lower than the lower edge of the rear end of the liquid interface 9 when the dirt collection box 3 is loaded into the accommodating cavity 4, thereby facilitating the flow.

[0044] In some embodiments, the dirt collection box 3 further comprises an openable cover 16 and an upper opening 17, which is also the upper opening of the dirt collection bin. When the cover 16 and the upper opening 17 are detachably connected, the dirt collection bin is located below the cover 16. When the cover 16 is opened, the dirt collection bin is in an upwardly open state to facilitate the pouring of dirt and cleaning. Since the upper opening 17 is in an upwardly open state, it is convenient to pour dirt and wash under the faucet. The foregoing scheme is of great significance to the dirt collection floor brush of the present disclosure, i.e., such a dirt collection floor brush needs to be cleaned frequently, so it is crucial to improve the convenience and efficiency of cleaning.

[0045] Preferably, as shown, Figure 3 , 4As shown in Figure 5, in the case where the first sludge collection chamber 13 is located behind the second sludge collection chamber 14 and a connecting channel 15 is provided on the upper side of the second sludge collection chamber 14, the sludge collection box 3 also includes an openable cover 16 and an upper opening 17. The upper opening 17 is also the upper opening 17 of the first sludge collection chamber 13. When the cover 16 and the upper opening 17 are detachably connected, the first sludge collection chamber 13 is located below the cover 16. A front-to-back connecting gap is formed between the cover 16 and the front bottom surface 18 of the first sludge collection chamber 13. This front-to-back connecting gap serves as the connecting channel 15. When the cover 16 is opened, the first sludge collection chamber 13 is in an upward-opening state to facilitate emptying the dirt and cleaning. With this design, the structure is optimized to distinguish the types of dirt. On the other hand, opening the cover 16 allows the connecting channel 15 and the first dirt collection tank 13 to be fully open upwards, which makes it convenient to empty the dirt. Furthermore, since impurities in liquid dirt may accumulate on the surface of the connecting channel 15 and the first dirt collection tank 13, the aforementioned solution makes it easy to rinse the connecting channel 15 and the first dirt collection tank 13, improving cleaning convenience and efficiency.

[0046] Furthermore, for the sake of a compact structure, the second waste collection chamber 14 is located on the lower side of the front bottom surface 18.

[0047] In some embodiments, for the sake of a compact structure, such as Figure 3 As shown, the upper side of the comb teeth 12 serves as the bottom surface of the liquid interface 9, and the front top edge of the upper side of the comb teeth 12 serves as the front lower edge 19 of the liquid interface 9.

[0048] In some embodiments, to improve storage capacity and prevent dirt from returning to the brush chamber, such as Figure 3 As shown, the lower edge 21 of the solid inlet 8 is raised above the inner bottom surface 20 of the second sludge collection chamber 14 to form a baffle 29.

[0049] Furthermore, such as Figure 3 As shown, the lower bottom surface 23 of the solid interface 10 is set higher than the lower edge 21 of the solid inlet 8, which helps to prevent dirt from returning from the solid interface 10 to the brush chamber during the dirt collection process.

[0050] In some embodiments, such as Figure 3 , 7 As shown, the liquid interface 9 is provided with a first sealing strip 25 on the side of the liquid inlet 7. In this example, it is provided on the lower rear end of the liquid interface 9. When the sludge collection box 3 is installed in the receiving cavity 4, the first sealing strip 25 is sealed and fitted with the side of the liquid inlet 7. This helps to reduce the risk of leakage at the connection between the liquid interface 9 and the liquid inlet 7, thereby facilitating the collection of liquid dirt.

[0051] Of course, a second sealing strip can also be provided on the solid inlet 8 side of the solid interface 10. When the sludge collection box 3 is installed in the receiving cavity 4, the second sealing strip seals with the solid inlet 8 side, which helps to prevent solid dirt from falling into the receiving cavity 4.

[0052] In some embodiments, such as Figure 3 , 7 As shown in Figure 8, a bottom shell 26 is provided at the bottom of the receiving cavity 4, extending towards the solid interface 10 and further into the roller brush cavity. The portion of the bottom shell 26 located in the roller brush cavity serves as an extension fitting portion 28, which is rotatably fitted with the roller brush 2. The bottom shell 26 is arched at the solid interface 10, and this arched arch serves as the lower bottom surface 23 of the solid interface 10. In this way, the bottom shell 26 forms a better collection channel, allowing the dirt scraped off by the comb teeth 12 to be promptly guided into the dirt collection bin when the roller brush 2 rotates. The arched arch, as the lower bottom surface 23 of the solid interface 10, also forms a barrier, thereby helping to prevent dirt from returning from the solid interface 10 to the roller brush cavity during the dirt collection process.

[0053] In particular, since the bottom of the receiving cavity 4 is provided with a bottom shell 26 extending towards the solid interface 10 and further into the roller brush cavity, the bottom shell 26 serves as the bottom of the receiving cavity 4 on the one hand, and on the other hand, it also provides the bottom surface 23 of the solid interface 10. Therefore, the structure is more compact and it is also beneficial to reduce the height of the entire dirt collection brush, which is important.

[0054] Furthermore, the bottom shell 26 provides a mating surface 27 as a second sealing strip. When the sludge collection box 3 is installed in the receiving cavity 4, the mating surface 27 is in close contact with the solid inlet 8. This structure is simple, and the close contact provides a certain degree of sealing, which helps to prevent solid dirt from falling into the receiving cavity 4.

[0055] When understanding this disclosure, the above structure may be referred to other embodiments / appendices if necessary. Figure 1 And that is understood, so I will not elaborate further here.

[0056] The above description is merely an illustrative embodiment of the present invention. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of the present invention are included within the scope of protection of the present invention.
