Description

Technical Field

[0001] The utility model relates to the technical field of sweepers, and in particular to a roller brush cleaning auxiliary mechanism, a roller brush assembly and a sweeper. Background Art

[0002] With the continuous development of society, people's material needs are increasing day by day, and the emergence of sweeping machines has satisfied people's vision of solving the problem of hands-on cleaning in the home environment. People no longer need to clean the floors and carpets by themselves. Sweeping machines not only appear in home environments, but also gradually appear in some open public environments such as office buildings, subway stations and high-speed rail stations. The emergence of sweeping machines has brought great convenience to people.

[0003] Sweeping machines can be classified according to the cleaning principle into sweeping machines without roller brushes and sweeping machines with roller brushes. Sweeping machines without roller brushes have unsatisfactory cleaning effects because they rely solely on suction to clean the surface to be cleaned. Since the garbage and water stains on the ground are cleaned purely by the suction of the fan, garbage or water stains are easily missed during the cleaning process. Sweeping machines with roller brushes, although they have added roller brushes to sweep or scrub the ground, thereby enhancing the cleaning effect, may still leave a little garbage or residual water stains. Utility Model Content

[0004] (1) Technical issues to be resolved

[0005] The technical problem to be solved by the present invention is to provide a roller brush cleaning auxiliary mechanism, a roller brush assembly and a sweeper, in which an elastic scraping strip that can move up and down is provided at the rear side of the cleaning roller brush in the travel direction of the sweeper, which can adapt to surfaces to be cleaned at different heights, so that one end of the elastic scraping strip is always in contact with the surface to be cleaned, thereby solving the problem of garbage missing and improving the cleaning effect and efficiency.

[0006] (2) Technical solution

[0007] The solution adopted by the utility model to solve the above technical problems is a roller brush cleaning auxiliary mechanism, which includes

[0008] a body having an opening for access to dirt;

[0009] An elastic scraper strip is provided at a rear side of the opening in the travel direction of the sweeper; and one end of the elastic scraper strip is capable of extending out of the body and abutting against the surface to be cleaned;

[0010] The elastic scraper strip can move up and down relative to the opening in a direction perpendicular to the travel direction of the sweeper, so that one end of the elastic scraper strip always contacts the surface to be cleaned.

[0011] Specifically, "penetrable" means capable of being passed through various means, including vacuum adsorption or motor-driven drawing; dirt can be solid objects such as debris, dust, gravel, noodles, food residues, etc., or undried water stains formed by liquids such as sewage and clean water, or dried water stains, or solid-liquid mixtures, such as a mixture of soup and noodles spilled on the ground, or tea with tea residue spilled on the ground, etc. Regardless of whether the above liquids are dry or not, they are all water stains and dirt, and the mixture can also be cleaned; the surface to be cleaned can be the floor and carpet to be cleaned.

[0012] By adopting the above scheme, an elastic scraper that can move up and down is provided at the rear side of the opening in the direction of travel of the sweeper, which can adapt to surfaces to be cleaned at different heights, so that one end of the elastic scraper is always against the surface to be cleaned, solving the problem of missing garbage and improving the cleaning effect and efficiency.

[0013] In some embodiments, the elastic scraper is assembled on the main body at one end thereof that is placed in the opening along its movement direction; and the elastic scraper is arranged on the main body at an angle along the travel direction of the sweeper, so that a deformation space for the elastic scraper to deform is formed between the elastic scraper and the main body.

[0014] Specifically, the elastic scraping strips arranged obliquely along the travel direction of the sweeper can better scoop up the objects to be cleaned than the elastic scraping strips arranged vertically or horizontally.

[0015] By adopting the above solution, one end of the elastic scraper is fixedly connected to the part of the main body located in the opening, so that there is no gap between the elastic scraper and the main body, thereby allowing garbage to completely enter the opening; the setting of the deformation space allows the elastic scraper to have space for deformation, thereby reducing the resistance of the elastic scraper.

[0016] In some embodiments, the elastic scraper includes a fixing portion assembled on the body; and the elastic scraper is provided with a deformation portion near the fixing portion.

[0017] In some embodiments, the elastic scraper includes a fixing portion, a deformation portion, a self-weight portion, and an abutment portion arranged in sequence from top to bottom along its inclination direction; and the deformation portion is the portion with the thinnest wall thickness, which can bend and deform after being subjected to the squeezing force of the surface to be cleaned; the self-weight portion is the portion with the thickest wall thickness, which provides self-weight for the downward movement of the elastic scraper; and the abutment portion is the portion that abuts against the surface to be cleaned.

[0018] Specifically, the rear wall of the deformed portion is very thin, so when the sweeper encounters a higher surface to be cleaned during cleaning, it will bend and deform under force, so that the abutment portion abuts against the surface to be cleaned; and when it subsequently sweeps a lower surface to be cleaned, the rebound force of the deformed portion caused by the bending deformation will give its own weight portion and the abutment portion a downward force, so that the abutment portion abuts against the surface to be cleaned; at the same time, since the wall thickness of the own weight portion is very thick, its own gravity will also give the deformed portion a downward force in the process, providing a downward force for the recovery of the deformed portion, making the recovery process smoother.

[0019] In some embodiments, one end of the self-weight portion away from the deformation portion is bent toward the travel direction of the sweeping machine to form the abutment portion.

[0020] Specifically, the lower end surface of the abutment portion abuts against the surface to be cleaned, thereby increasing its contact area with the ground and improving the sealing performance, thereby solving the problem of water stains and garbage leaking from between the abutment portion and the surface to be cleaned. At the same time, the abutment portion can also perform secondary cleaning on the surface to be cleaned during this process, scraping off water stains and achieving a better cleaning effect.

[0021] In some embodiments, a plurality of mounting portions arranged along the length direction of the elastic scraper are provided at one end of the body away from the surface to be cleaned; and the fixing portion includes a plurality of mounting mating portions capable of mating with the mounting portions.

[0022] In some embodiments, the plurality of mounting portions are a plurality of spaced-apart protrusions; the plurality of mounting mating portions are a plurality of spaced-apart slots; and the stability of the elastic scraper strip on the main body is improved, making it less likely to fall off.

[0023] In some embodiments, a scraper bar mounting member for mounting the elastic scraper bar is further included, wherein the scraper bar mounting member is adapted in the opening and has an open portion communicating with the opening; wherein the scraper bar mounting member has two ends along the travel direction of the sweeper, one end of which is used to fix the elastic scraper bar, and the other end is rotatably connected to the main body.

[0024] In some embodiments, the scraper strip mounting member is fixed on the deadweight portion of the elastic scraper strip, making the installation more stable.

[0025] With the above solution, one end of the scraper strip mounting member is rotatably connected to the body, so that the elastic scraper strip can move up and down more smoothly.

[0026] In some embodiments, the opening is a strip-shaped opening that can accommodate a cleaning roller brush; the elastic scraper is a strip-shaped elastic scraper; and the elastic scraper is arranged along the length direction of the opening.

[0027] With the above solution, the strip-shaped opening can accommodate the long strip-shaped cleaning roller brush, and the elastic scraper strip is arranged along the length direction of the opening, which can further scrape the cleaning surface brushed by the cleaning roller brush, so that water stains and garbage are scraped away.

[0028] The solution adopted by the present invention to solve the above-mentioned technical problems is a roller brush assembly, including a cleaning roller brush, a roller brush mounting seat, and a roller brush cleaning auxiliary mechanism as mentioned above; the roller brush mounting seat has a cleaning inlet that is connected to the opening of the roller brush cleaning auxiliary mechanism; the cleaning roller brush is rotatably connected to the roller brush mounting seat; the main body of the roller brush cleaning auxiliary mechanism is detachably connected to the roller brush mounting seat, and the elastic scraper of the roller brush cleaning auxiliary mechanism is arranged relative to the cleaning roller brush at the rear side of the travel direction of the sweeper to which it belongs.

[0029] In some embodiments, the main body is connected to the roller brush mounting seat by a snap connection, which facilitates the disassembly and assembly of the roller brush cleaning auxiliary mechanism on the roller brush mounting seat, is beneficial for subsequent maintenance and replacement, and relatively saves costs.

[0030] The solution adopted by the present invention to solve the above technical problems is a sweeping machine, which includes a main body and a roller brush assembly as described above connected to the main body.

[0031] (3) Beneficial effects

[0032] Compared with the prior art, the utility model designs a roller brush cleaning auxiliary mechanism, a roller brush assembly and a sweeper.

[0033] (1) The utility model is provided with an elastic scraper strip that can move up and down at the rear side of the cleaning roller brush in the direction of travel of the sweeper, which can adapt to surfaces to be cleaned at different heights, so that one end of the elastic scraper strip always contacts the surface to be cleaned, thereby solving the problem of garbage being missed and improving the cleaning effect and efficiency;

[0034] (2) The utility model sets one end of the elastic scraper to be fixedly connected to the portion of the body located in the opening, so that there is no gap between the elastic scraper and the body, thereby allowing garbage to completely enter the opening; the setting of the deformation space allows the elastic scraper to have a space for deformation, thereby reducing the resistance of the elastic scraper;

[0035] (3) The rear wall of the deformable portion of the present invention is very thin. When the sweeper encounters a higher surface to be cleaned during cleaning, it will bend and deform under force, so that the abutting portion abuts against the surface to be cleaned.

[0054] The following describes the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0055] like Figure 1-Figure 5As shown, an embodiment of the present invention provides a roller brush cleaning auxiliary mechanism, comprising a body 101, which has an opening 1011 for admitting dirt; an elastic scraper 102, which is arranged at a rear side position of the opening 1011 in the travel direction of the sweeper to which it belongs; and one end of the elastic scraper 102 can extend out of the body 101 and abut against the surface to be cleaned; the elastic scraper 102 can move up and down relative to the opening 1011 in a direction perpendicular to the travel direction of the sweeper to which it belongs, so that one end of the elastic scraper 102 always abuts against the surface to be cleaned. By adopting the above scheme, an elastic scraper 102 that can move up and down is provided at a rear side position of the opening 1011 in the travel direction of the sweeper, which can adapt to surfaces to be cleaned of different heights, so that one end of the elastic scraper 102 always abuts against the surface to be cleaned, thereby solving the problem of missing garbage and improving the cleaning effect and efficiency. In some embodiments, the end of the elastic scraper 102 positioned within the opening 1011 along its direction of motion is assembled to the body 101. Furthermore, the elastic scraper 102 is tilted along the travel direction of the sweeper, forming a deformation space 103 between the elastic scraper 102 and the body 101 for the elastic scraper 102 to deform. Specifically, the elastic scraper 102 tilted along the travel direction of the sweeper can better scoop up cleaned material compared to elastic scrapers 102 positioned vertically or horizontally. Using this solution, one end of the elastic scraper 102 is fixedly connected to the portion of the body 101 located within the opening 1011, eliminating any gap between the elastic scraper 102 and the body 101, allowing waste to completely enter the opening 1011. The provision of the deformation space 103 provides the elastic scraper 102 with room to deform, reducing resistance to the elastic scraper 102.

[0056] In some embodiments, the elastic scraper 102 includes a fixing portion 1021 assembled on the body 101; and the elastic scraper 102 is provided with a deforming portion 1022 near the fixing portion 1021. In some embodiments, the elastic scraper 102 includes a fixing portion 1021, a deforming portion 1022, a self-weight portion 1023, and an abutting portion 1024 arranged in sequence from top to bottom along its inclination direction; and the deforming portion 1022 is the thinnest portion, which can bend and deform after being squeezed by the surface to be cleaned; the self-weight portion 1023 is the thickest portion, which provides self-weight for the downward movement of the elastic scraper 102; and the abutting portion 1024 is the portion that abuts the surface to be cleaned. Specifically, the rear wall of the deformable portion 1022 is very thin, so when the sweeper encounters a higher surface to be cleaned during cleaning, it will bend and deform under force, so that the abutment portion 1024 abuts against the surface to be cleaned; and when it subsequently sweeps a lower surface to be cleaned, the rebound force of the deformable portion 1022 bending and deforming will give its own weight portion 1023 and the abutment portion 1024 a downward force, so that the abutment portion 1024 abuts against the surface to be cleaned; at the same time, since the wall thickness of the own weight portion 1023 is very thick, its own gravity will also give the deformable portion 1022 a downward force during this process, providing a downward force for the recovery of the deformable portion 1022, making the recovery process smoother. In some embodiments, the end of the own weight portion 1023 away from the deformable portion 1022 is bent toward the direction of travel of the sweeper to which it belongs to form the abutment portion 1024. Specifically, the lower end surface of the abutment portion 1024 abuts against the surface to be cleaned, thereby increasing its contact area with the ground and improving sealing performance. This solves the problem of water stains and garbage leaking between the abutment portion 1024 and the surface to be cleaned. At the same time, the abutment portion 1024 can also perform a secondary cleaning on the surface to be cleaned during this process, scraping off water stains for a better cleaning effect. In some embodiments, the end of the main body 101 facing away from the surface to be cleaned is provided with a plurality of mounting portions 1012 arranged along the length direction of the elastic scraper 102; the fixing portion 1021 includes a plurality of mounting mating portions 1021a capable of mating with the mounting portion 1012. In some embodiments, the plurality of mounting portions 1012 are a plurality of spaced-apart protrusions; the plurality of mounting mating portions 1021a are a plurality of spaced-apart slots; this improves the stability of the elastic scraper 102 on the main body 101 and prevents it from detaching.

[0057] In some embodiments, a scraper bar mounting member 104 for mounting the elastic scraper bar 102 is further included. The scraper bar mounting member 104 fits within the opening 1011 and has an open portion 1041 communicating with the opening 1011. The scraper bar mounting member 104 has two ends along the travel direction of the sweeper, one end of which is used to secure the elastic scraper bar 102, and the other end is rotatably connected to the body 101. In some embodiments, the scraper bar mounting member 104 is fixed to the deadweight portion 1023 of the elastic scraper bar 102 for a more stable installation. With this solution, one end of the scraper bar mounting member 104 is rotatably connected to the body 101, allowing for smoother up and down movement of the elastic scraper bar 102.

[0058] In some embodiments, the opening 1011 is a strip-shaped opening 1011 that can accommodate the cleaning roller brush 201; the elastic scraping strip 102 is a strip-shaped elastic scraping strip 102; and the elastic scraping strip 102 is arranged along the length of the opening 1011. With this solution, the strip-shaped opening 1011 can accommodate the long strip-shaped cleaning roller brush 201, and the elastic scraping strip 102 is arranged along the length of the opening 1011, which can further scrape the cleaning surface brushed by the cleaning roller brush 201, so that water stains and garbage are scraped away.

[0059] like Figure 6-Figure 7 As shown, based on the same inventive concept, an embodiment of this specification further provides a roller brush assembly 200, comprising a cleaning roller brush 201, a roller brush mounting seat 202, and the roller brush cleaning auxiliary mechanism 100 as described above; the roller brush mounting seat 202 has a cleaning inlet 2021 that communicates with the opening 1011 of the roller brush cleaning auxiliary mechanism 100; the cleaning roller brush 201 is rotatably connected to the roller brush mounting seat 202; the body 101 of the roller brush cleaning auxiliary mechanism 100 is detachably connected to the roller brush mounting seat 202, and the elastic scraper 102 of the roller brush cleaning auxiliary mechanism 100 is positioned relative to the cleaning roller brush 201 at the rear side of the travel direction of the sweeper. In some embodiments, the body 101 is connected to the roller brush mounting seat 202 via a snap-fit ​​connection, which facilitates the disassembly and assembly of the roller brush cleaning auxiliary mechanism 100 to the roller brush mounting seat 202, facilitates subsequent maintenance and replacement, and relatively saves costs.

[0060] like Figure 8 As shown, based on the same inventive concept, the embodiment of this specification also provides a sweeping machine, including a main body 300 and a roller brush assembly 200 as described above connected to the main body 300.

[0061] The same or similar parts between the various embodiments in this specification can be referred to each other, and each embodiment focuses on the differences from other embodiments.

[0062] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
