Description

Technical Field

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

[0002] During operation, vacuum cleaners typically use a motor to drive the blades to rotate at high speed, creating negative air pressure within the sealed housing to suck up dust and debris. The floor brush is the core component of the vacuum cleaner, used to clean dust, debris, and dirt from floors and ground surfaces. It is usually located at the bottom of the vacuum cleaner, in contact with the ground, and has rotating bristles or a roller brush to effectively sweep and capture dust and dirt.

[0003] For example, CN202322605789.0 discloses a vacuum cleaner floor brush, including a floor brush housing, with a roller and an air inlet on the bottom surface of the floor brush housing. A curved tube is connected to the rear side of the floor brush housing, and the air inlet is located on the front side of the roller. It also includes: a U-shaped sealing groove, which surrounds the roller and is located on the bottom surface of the floor brush housing. The opening of the U-shaped sealing groove is connected to the air inlet, limiting the suction range of the air inlet; and a U-shaped sealing strip, which is located inside the U-shaped sealing groove. This utility model can effectively seal the gap around the roller of the vacuum cleaner floor brush, prevent air from escaping from the bottom, create a sealed vacuum environment, enable the vacuum cleaner to generate suction more effectively, thereby improving the vacuuming performance. At the same time, it reduces noise and is easy to move.

[0004] Based on the above, during the long-term use of vacuum cleaner floor brushes, when cleaning wet waste such as vegetable leaves and leftover food, it is very easy for the wet waste to ferment and stick together in the suction port. This not only blocks the channel and breeds bacteria, causing a significant decrease in suction power and affecting cleaning efficiency, but also makes it very easy for the heat generated by the motor to be difficult to dissipate in time due to the blockage of the suction port, resulting in overload of the core components and affecting the service life of the vacuum cleaner floor brush. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a foldable and retractable vacuum cleaner floor brush. This addresses the issue that during long-term use, when cleaning wet waste such as vegetable scraps and leftover food, the wet waste easily ferments and sticks inside the suction port. This not only clogs the channel and breeds bacteria, leading to a significant decrease in suction power and affecting cleaning efficiency, but also makes it difficult for the heat generated by the motor to dissipate in time due to the clogged suction port, causing overload of core components and affecting the lifespan of the vacuum cleaner floor brush.

[0006] The purpose and function of this foldable and retractable vacuum cleaner floor brush are achieved through the following specific technical means: A foldable and retractable vacuum cleaner floor brush includes a connecting bracket, a protective shell, a suction port, roller brushes, a transmission bracket, and a guiding auxiliary mechanism. The protective shell is hinged to the outside of the bottom end face of the connecting bracket; the suction port is located on the bottom end face of the protective shell; there are two roller brushes, each rotatably connected to the bottom end face of the protective shell via a connecting shaft, with the roller brushes positioned on the front and rear sides of the suction port; the transmission bracket is slidably connected to the suction port; the guiding auxiliary mechanism is located on the outside of the transmission bracket; the guiding auxiliary mechanism includes a reciprocating screw and guiding auxiliary blocks, the reciprocating screw being rotatably connected to the protective shell, and the upper end of the transmission bracket being threadedly connected to the reciprocating screw via a threaded pair; there are two guiding auxiliary blocks, each slidably positioned at the left and right ends of the transmission bracket.

[0007] Furthermore, a positioning through hole is provided on one side of the connecting bracket; a rubber positioning plug is fixedly connected to the outer end of the protective support shell; the rubber positioning plug is adapted to the positioning through hole.

[0008] Furthermore, the front and rear ends of the transmission bracket are elastically connected to elastic pillars by springs; an auxiliary scraper is fixedly connected to the outer end of the elastic pillar; the auxiliary scraper has a semi-arc sawtooth structure, and the auxiliary scraper on the same side is in contact with the roller brush.

[0009] Furthermore, the dredging auxiliary mechanism also includes: a drive gear, an adjusting gear, and a transmission gear. There are two drive gears, which are coaxially fixedly connected to the left and right sides of the front connecting support shaft, respectively. There are two adjusting gears, which are rotatably connected to the left and right ends of the protective support shell, respectively. There are two transmission gears, which are coaxially fixedly connected to the left and right ends of the reciprocating lead screw, respectively. The front and rear sides of the adjusting gear on the same side mesh with the drive gear and the transmission gear, respectively.

[0010] Furthermore, the dredging auxiliary block is slidably connected to the transmission support via a resistance-increasing frame; the resistance-increasing frame is a T-shaped slider structure, and a resistance-increasing groove is provided at the alignment position of the transmission support and the resistance-increasing frame.

[0011] Furthermore, the dredging auxiliary mechanism also includes: driving guide posts and driving guide grooves. There are two driving guide posts, which are fixedly connected to two dredging auxiliary blocks respectively. There are two driving guide grooves, which are opened inside the protective support shell and are located on the front and rear sides of the dust suction port. The driving guide posts on the same front and rear sides are slidably connected to the driving guide grooves, and the driving guide grooves have a wave groove structure.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In use, this invention utilizes the cooperation of a transmission bracket and a semi-arc-shaped serrated auxiliary scraper to achieve automatic cleaning of the roller brush. When the reciprocating screw drives the transmission bracket to slide left and right, the auxiliary scraper can actively remove hair and fibers wrapped around the surface of the roller brush, preventing them from clogging the gaps in the roller brush and reducing the air intake area and suction power. At the same time, the elastic support column, through the spring force, always pushes the auxiliary scraper to keep in contact with the roller brush. Even if the roller brush shows slight wear due to long-term use or has protruding foreign objects on its surface, the auxiliary scraper can still adaptively keep in contact, ensuring the cleaning effect. It also avoids the problem of increased roller brush rotation resistance and increased motor load caused by long-term hair wrapping, thus extending the service life of the roller brush and motor. This invention employs a multi-dimensional anti-clogging solution using a guiding auxiliary mechanism. The force of the rotating brush drives the reciprocating screw and transmission bracket, eliminating the need for an additional motor and achieving an energy-saving design where the cleaning process is simultaneously an anti-clogging process. Simultaneously, as the transmission bracket slides, the wave-groove structure of the drive guide groove cooperates with the drive guide post, causing the guiding auxiliary block to slide left and right while simultaneously undulating up and down, creating a three-dimensional scraping action. This action can penetrate deep into the crevices of the suction port, thoroughly scraping away adhered wet debris and drawing it into the vacuum cleaner with the airflow. This prevents residual wet debris from fermenting, breeding bacteria, and producing odors. It also prevents airflow obstruction and motor heat buildup caused by blockages, greatly avoiding suction power reduction and motor overload damage due to suction port blockage. This ensures a hygienic environment after floor cleaning and extends the lifespan of the vacuum cleaner's core components. Attached Figure Description

During the rotation of the reciprocating screw 6, the transmission bracket 5 is driven to slide left and right. During the left and right sliding of the transmission bracket 5, the auxiliary scraper 502 automatically cleans the hair and fibers attached to the surface of the roller brush 4, avoiding the phenomenon that the air intake area of ​​the suction port 3 is reduced due to the long-term attachment and entanglement of hair and fibers on the surface of the roller brush 4. The elastic support 501 keeps the auxiliary scraper 502 in close contact with the roller brush 4, ensuring the cleaning effect of the roller brush 4. Example 2

[0025] As attached Figure 3To be continued Figure 6 As shown: Based on Embodiment 1, a dredging auxiliary mechanism is also included, which is located on the outside of the transmission bracket 5. The dredging auxiliary mechanism includes a reciprocating screw 6 and a dredging auxiliary block 604. The reciprocating screw 6 is rotatably connected to the protective support shell 2, and the upper end of the transmission bracket 5 is threadedly connected to the reciprocating screw 6 through a threaded pair.
