Description

Technical Field

[0001] This utility model belongs to the field of vacuum cleaner technology, and more specifically, it relates to a vacuum cleaner floor brush with a scraping function. Background Technology

[0002] As a commonly used cleaning device, the floor brush of a vacuum cleaner is a key component that directly contacts the floor to be cleaned. Its main function is to suck up dust, debris, and other impurities from the floor. Existing vacuum cleaner floor brushes with scraping functions typically consist of a brush body, a connecting mechanism, a drive mechanism, and a scraping roller brush. The connecting mechanism ensures a secure connection between the brush body and the vacuum cleaner's main unit, while also ensuring unobstructed suction to transmit negative pressure. The drive mechanism provides power, using a motor and gear set to rotate the scraping roller brush. The friction between the brush bristles or scraper strips and the floor removes stubborn stains, further enhancing the cleaning effect beyond just vacuuming.

[0003] Existing application number CN201720302078.8 discloses a vacuum cleaner floor brush, comprising a housing, a first roller, a steering joint, a pedal, a hose, a floor brush lower cover, and a second roller. The housing is fixed to the floor brush lower cover; the floor brush lower cover has an air inlet; the first roller is mounted on both sides of the housing; the steering joint is rotatably mounted on one end of the housing; one end of the hose is sealed to the steering joint, and the other end is sealed to the air inlet; the pedal is rotatably mounted on the upper end of the housing; the second roller is mounted on both sides of the lower end of the floor brush lower cover; and inclined surfaces are provided on the floor brush lower cover on both sides of the air inlet. This utility model has a simple structure. The inclined surfaces on both sides of the air inlet reduce the area of ​​the air inlet, increase the pressure, and increase the suction power, causing dust to be blown more concentrated towards the air inlet, preventing dust from scattering, thus aiding in dust collection and suction, and improving vacuuming efficiency.

[0004] Based on the above, existing vacuum cleaner floor brushes with scraping functions are insufficient to completely remove stubborn stains such as dried beverage stains and sticky food residues, relying solely on their suction or scraping mechanism. Ultimately, users still need to manually scrape and clean with tools such as scrapers and cloths, which is cumbersome and increases the workload. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a vacuum cleaner floor brush with a scraping function. This solves the issue that existing vacuum cleaner floor brushes with scraping functions, when faced with stubborn stains such as dried beverage stains and sticky food residue, cannot completely remove the stains using only their own suction or scraping mechanism. Ultimately, users still need to manually scrape and clean with tools such as scrapers and cloths, which is cumbersome and increases the workload.

[0006] The purpose and function of this utility model of a vacuum cleaner floor brush with a scraping function are achieved by the following specific technical means: A vacuum cleaner floor brush with a scraping function includes a floor brush body, a collecting air duct, a connecting pipe, a scraping roller brush, scraper blades, a scraper assembly, and an air duct assembly. The collecting air duct is fixedly installed on the upper part of the floor brush body; the connecting pipe is fixedly connected to the upper part of the collecting air duct; the scraping roller brush is rotatably connected inside the floor brush body; the scraper blades are hinged to the bottom of the floor brush body; the scraper assembly is disposed inside the floor brush body; and the air duct assembly is disposed inside the floor brush body.

[0007] Furthermore, the scraper assembly includes a first air duct and a second air duct, wherein the first air duct is formed inside the brush body; and the second air duct is formed inside the brush body.

[0008] Furthermore, the scraper assembly also includes: a drive push rod and a transmission frame. The drive push rod is provided in two sets, and the two sets of drive push rods are fixedly installed on the left and right sides of the floor brush body. The transmission frame is provided in two sets, and the two sets of transmission frames are slidably connected to the left and right sides of the floor brush body, respectively. The two sets of transmission frames are fixedly connected to the two sets of drive push rods.

[0009] Furthermore, the scraper assembly also includes: a first rotating shaft and a first gear, the first rotating shaft being rotatably connected to the bottom of the floor brush body and fixedly connected to the inside of the scraper blade; the first gear is provided in two sets, and the two sets of the first gear are coaxially and fixedly installed at both ends of the first rotating shaft.

[0010] Furthermore, the scraper assembly also includes: a first rack, which is provided in two sets, and the two sets of the first rack are respectively fixedly installed at the ends of the two sets of transmission frames, and the first rack and the first gear mesh with each other.

[0011] Furthermore, the air duct assembly includes a second rotating shaft and a guide vane, wherein the second rotating shaft is rotatably connected inside the floor brush body; and the guide vane is fixedly connected to the outside of the second rotating shaft.

[0012] Furthermore, the air duct assembly also includes: a second rack and a second gear, wherein two sets of the second rack are provided, and the two sets of the second rack are fixedly installed on the top of the two sets of transmission frames; two sets of the second gear are provided, and the two sets of the second gear are coaxially fixedly installed at both ends of the second rotating shaft, and the second gear and the second rack mesh with each other.

[0013] Compared with the prior art, the present invention has the following beneficial effects: Firstly, this utility model features a scraper assembly. A drive push rod drives the transmission frame to slide, and in conjunction with the meshing transmission of a rack and pinion, the scraper blades can swing around a rotating shaft. Normally, the scraper blades adhere to the bottom of the floor brush body, blocking the second air duct without affecting regular vacuuming. When encountering stubborn stains, the scraper blades can swing downwards close to the ground, using the scraping force to break up dried beverage stains, sticky food residue, and other stubborn stains. Simultaneously, the second air duct is opened, enabling the removal of stubborn stains and the adsorption of debris to occur simultaneously. No additional manual operation is required from the user, significantly simplifying the cleaning process and reducing the workload.

[0014] Secondly, this invention features an air duct assembly. A rack and pinion drive gear, linked to the transmission frame, rotates, causing the air guide vane to deflect within the collecting air duct. When the scraper blades begin scraping, the air guide vane swings towards the first air duct, narrowing the first air duct opening and widening the second air duct opening. This allows more negative pressure from the vacuum cleaner to converge into the second air duct, enhancing the suction power after removing stubborn stains, preventing stain debris residue or splashing, and further improving cleaning thoroughness. This works efficiently with the scraper assembly.

[0015] This utility model has the advantages of cleaning stubborn stains, simple operation, and air duct linkage. It not only solves the problem of existing floor brushes not cleaning stubborn stains thoroughly, but also realizes the linkage distribution of negative pressure suction, taking into account both the efficiency of conventional vacuuming and the cleaning effect of stubborn stains. The overall structure is compact and easy to operate, and can be adapted to a variety of floor cleaning scenarios. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. Example 1

[0023] As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a vacuum cleaner floor brush with a scraping function, including a floor brush body 1, a collecting air duct 2, a connecting pipe 3, a scraping roller brush 4, a scraper blade 5, and a scraper assembly. The collecting air duct 2 is fixedly installed on the upper part of the floor brush body 1; the connecting pipe 3 is fixedly connected to the upper part of the collecting air duct 2; the scraping roller brush 4 is rotatably connected to the inside of the floor brush body 1; the scraper blade 5 is hinged to the bottom of the floor brush body 1; and the scraper assembly is disposed inside the floor brush body 1.

[0024] The scraper assembly includes a first air duct 101 and a second air duct 102. The first air duct 101 is located inside the brush body 1, and the second air duct 102 is located inside the brush body 1.

[0025] The scraper assembly also includes: a drive push rod 6 and a transmission frame 601. Two sets of drive push rods 6 are provided, and the two sets of drive push rods 6 are fixedly installed on the left and right sides of the floor brush body 1. Two sets of transmission frames 601 are provided, and the two sets of transmission frames 601 are slidably connected to the left and right sides of the floor brush body 1, respectively. The two sets of transmission frames 601 are fixedly connected to the two sets of drive push rods 6.

[0026] The scraper assembly also includes a first rotating shaft 501 and a first gear 502. The first rotating shaft 501 is rotatably connected to the bottom of the floor brush body 1 and is fixedly connected to the inside of the scraper blade 5. Two sets of first gears 502 are provided, and the two sets of first gears 502 are coaxially fixedly installed at both ends of the first rotating shaft 501.

[0027] The scraper assembly also includes a first rack 602, which is provided in two sets. The two sets of first racks 602 are respectively fixedly installed at the ends of the two sets of transmission frames 601, and the first racks 602 and the first gear 502 mesh with each other.

[0028] The specific usage and function of this embodiment are as follows: In use, first connect the floor brush body 1 to the vacuum cleaner hose via the connecting port 3 to create a complete suction path. Under normal cleaning conditions, the scraper blade 5 is hinged to the bottom of the floor brush body 1 via the first rotating shaft 501 and fits tightly, simultaneously blocking the second air duct 102; at this time, the negative pressure generated by the vacuum cleaner acts on the ground only through the first air duct 101, while the internal drive device of the floor brush body 1 drives the scraping roller brush 4 at the first air duct 101 to rotate synchronously, and the roller brush scraping is superimposed on the negative pressure adsorption, effectively removing dust, debris and other common debris.

[0029] When encountering stubborn stains such as dried beverage stains or sticky food residue, the vacuum cleaner control mechanism triggers the drive push rod 6 to start: the drive push rod 6 drives the transmission frame 601 to slide along the inside of the floor brush body 1, and the first rack 602 at the end of the transmission frame 601 moves together. Through the meshing of the rack and gear, the first gear 502 is driven to rotate, which in turn drives the first rotating shaft 501 connected to the same axis to rotate, causing the scraper blade 5 to swing down to be close to the ground, and the scraping force of the blade is used to remove stubborn stains; at the same time, the scraper blade 5 disengages from the blockage at the bottom of the floor brush body 1, and the second air duct 102 is opened simultaneously. The negative pressure can be used to simultaneously adsorb the scraped stains and debris through the dual air ducts, and finally be collected by the collecting air duct 2 and transported to the inside of the vacuum cleaner. Example 2

[0030] Based on Example 1, such as Figures 1 to 5 As shown, it also includes: an air duct assembly, which is located inside the floor brush body 1.

[0031] The air duct assembly includes a second rotating shaft 701 and a guide vane 7. The second rotating shaft 701 is rotatably connected inside the floor brush body 1; the guide vane 7 is fixedly connected to the outside of the second rotating shaft 701.

[0032] The air duct assembly also includes: a second rack 603 and a second gear 702. Two sets of second racks 603 are provided, and the two sets of second racks 603 are fixedly installed on the top of two sets of transmission frames 601. Two sets of second gears 702 are provided, and the two sets of second gears 702 are coaxially fixedly installed at both ends of the second rotating shaft 701. The second gears 702 and the second racks 603 mesh with each other.

[0033] The specific usage and function of this embodiment are as follows: When the drive push rod 6 is activated due to stubborn stains on the ground, it moves the transmission frame 601 to control the swing of the scraper blade 5, and simultaneously drives the two sets of second racks 603 at the top of the transmission frame 601 to move in the same direction. Since the second racks 603 mesh with the second gears 702 at both ends of the second rotating shaft 701, the movement of the second racks 603 drives the second gears 702 to rotate, which in turn drives the coaxially fixed second rotating shaft 701 to rotate synchronously. As the second rotating shaft 701 rotates, the air guide plate 7 fixed on its outer side will deflect towards the first air duct 101 inside the collecting air duct 2. Through the blocking effect of the air guide plate 7, the air outlet area of ​​the first air duct 101 corresponding to the collecting air duct 2 is reduced, while the air outlet area of ​​the second air duct 102 corresponding to the collecting air duct 2 is expanded. This allows more negative pressure generated by the vacuum cleaner to converge towards the second air duct 102, enhancing the suction force at the second air duct 102 and ensuring that stubborn stains and debris scraped off by the scraper blade 5 can be quickly and thoroughly sucked in, avoiding stain residue or splashing. This works in synergy with the scraping action of the scraper blade 5 to further optimize the cleaning effect of stubborn stains.
