Description

Technical Field

[0001] This utility model belongs to the field of floor cleaning machines. Background Technology

[0002] Common floor cleaning machines, including floor scrubbers and vacuum cleaners, all use roller brushes at the front of the floor brush to wipe the floor and pick up debris. The dirt is then sucked into the main unit by the brush's suction port for temporary storage, thus improving cleaning efficiency. However, the cylindrical shape of the roller brush makes it difficult to clean hard-to-reach areas when cleaning against walls, resulting in incomplete cleaning of the floor. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a floor cleaning machine with dual suction ports.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A floor cleaning machine with dual suction ports includes a main unit and a floor brush. The main unit is equipped with a suction device and is connected to the floor brush through a suction channel. The floor brush has a scrubbing roller brush that contacts the floor. The floor brush has a first suction port located behind the scrubbing roller brush and a second suction port located in front of the scrubbing roller brush. The floor brush has a docking channel inside that connects to the suction channel. The first and second suction ports are respectively connected to the docking channel, and a switching mechanism is arranged in the docking channel to switch the docking channel to connect with either the first or the second suction port. A switching switch is provided on the front surface of the floor brush. When the switching switch is triggered, it controls the switching mechanism to operate.

[0006] The floor brush includes a floor brush housing, and the docking channel and switching mechanism are arranged inside the floor brush housing. The floor cleaning roller brush is installed in the roller brush chamber at the front end of the floor brush housing. The roller brush chamber is open at the top and bottom, and a roller brush cover is provided on the top of the roller brush chamber. The floor cleaning roller brush contacts the ground through the opening at the bottom of the roller brush chamber. The first suction port is formed on the back side wall of the roller brush chamber and is connected to the switching mechanism. The roller brush cover extends to the front of the floor cleaning roller brush, and the switching switch is arranged on the surface of the roller brush cover. The roller brush cover has a front air duct inside and a second suction port is formed at the bottom of the cover in front of the floor cleaning roller brush. The rear side of the roller brush cover has a docking interface that connects to the front air duct and is connected to the switching mechanism.

[0007] A scraper is formed above the first suction port, and the scraper is in close contact with the surface of the floor cleaning roller.

[0008] The switching mechanism includes a first guide tube, a second guide tube, and a flip baffle; one end of the first guide tube is connected to a first suction port, and the other end forms a first guide port that cooperates with the flip baffle and is inserted into the docking channel; one end of the second guide tube is connected to a second suction port, and the other end forms a second guide port that cooperates with the flip baffle and is inserted into the docking channel; the flip baffle is driven by a flipping device to flip and block the first guide port or the second guide port.

[0009] The flipping device includes an electromagnetic drive rod and a drive plate. The flipping baffle is rotatably connected in the docking channel via a rotating shaft and is located between the first and second guide ports. The rotating shaft has an extension section that extends into the floor brush housing. The drive plate is arranged on the extension section. The electromagnetic drive rod pushes the drive plate through a telescopic push rod, thereby pushing the flipping baffle to rotate and back and forth between the first and second guide ports.

[0010] The first and second conductive tubes are arranged vertically. The flip-up baffle flips vertically via a rotating shaft. The electromagnetic drive rod is arranged below the rotating shaft. The push rod of the electromagnetic drive rod extends to push the drive plate, causing the flip-up baffle to rotate upward and block the second conductive port. The push rod of the electromagnetic drive rod retracts, and the flip-up baffle and the drive plate flip downward under the action of gravity to block the first conductive port.

[0011] The rotating shaft may also be equipped with a reset torsion spring, and the flip baffle is kept in the state of sealing the first guide port under the action of the reset torsion spring.

[0012] The length of the second suction port is greater than or equal to the length of the floor cleaning roller, and the two side walls of the front air duct slope towards the center and narrow, connecting to the opposite port.

[0013] The switching switch is arranged on the side of the front surface of the roller brush cover, and the front side of the roller brush cover has a mounting cavity for installing the switching switch.

[0014] The bottom front side of the roller brush cover is provided with a support column.

[0015] The beneficial effects of this utility model are as follows: This utility model adds a second suction port in front of the floor cleaning roller. Under normal circumstances, when the floor cleaning machine's brush cleans the floor, the floor cleaning roller works normally in conjunction with the first suction port. When it is necessary to clean corners or dead corners, the front side of the brush is placed against the front side wall, which triggers the switching switch. This controls the switching mechanism to switch the docking channel to connect with the second suction port, shutting off the operation of the first suction port. The second suction port then generates suction to remove dirt from the dead corner. After the brush leaves the corner, the switching switch moves away from the front side wall and automatically resets, cutting off the connection between the second suction port and the docking channel and restoring the connection of the first suction port.

[0024] Reference Figures 1 to 7 A floor cleaning machine with dual suction ports includes a main unit and a floor brush 2. The main unit is equipped with a suction device and is connected to the floor brush 2 through a suction channel. The floor brush 2 has a floor scrubbing roller brush 5 that contacts the floor. The floor brush 2 has a first suction port 25 located behind the floor scrubbing roller brush 5 and a second suction port 26 located in front of the floor scrubbing roller brush 5. The floor brush 2 has a docking channel 27 that connects to the suction channel. The first suction port 25 and the second suction port 26 are respectively connected to the docking channel 27, and a switching mechanism 3 is arranged in the docking channel 27 to switch the docking channel 27 to connect with either the first suction port 25 or the second suction port 26. A switch 4 is provided on the front surface of the floor brush 2. When the switch 4 is triggered, it can control the action of the switching mechanism 3. Under normal circumstances, when the floor brush 2 of the floor cleaning machine cleans the floor, the floor scrubbing roller brush 5 works normally in conjunction with the first suction port 25. When it is necessary to clean corners and dead corners, the front side of the floor brush 2 is pressed against the front side wall, which triggers the switch 4. This controls the switching mechanism 3 to switch the docking channel 27 to connect with the second suction port 26, shutting off the operation of the first suction port 25. The second suction port 26 then generates suction to suck away the dirt in the dead corner. After the floor brush 2 leaves the corner, the switch 4 moves away from the front side wall and automatically resets, cutting off the connection between the second suction port 26 and the docking channel 27 and restoring the connection of the first suction port 25, so that the floor cleaning work can continue normally.

[0025] As a preferred embodiment of this utility model, the floor brush 2 includes a floor brush housing 21, a docking channel 27, and a switching mechanism 3 arranged inside the floor brush housing 21; the floor cleaning roller brush 5 is installed in the roller brush chamber 23 at the front end of the floor brush housing 21, the roller brush chamber 23 is open at the top and bottom, and a roller brush cover 22 is provided on the top of the roller brush chamber 23. The floor cleaning roller brush 5 contacts the ground through the opening at the bottom of the roller brush chamber 23. A first suction port 25 is formed on the back side wall of the roller brush chamber 23 and is connected to the switching mechanism 3. A scraper 24 is formed above the first suction port 25, and the scraper 24 is in close contact with the surface of the floor cleaning roller brush 5. 4 scrapes off the dirt on the surface of the floor cleaning roller brush 5 and sucks it away by the first suction port 25; the roller brush cover 22 extends to the front of the floor cleaning roller brush 5 and the switch 4 is arranged on the surface of the roller brush cover 22. The roller brush cover 22 has a front air duct 221 inside and a second suction port 26 is formed at the bottom of the cover in front of the floor cleaning roller brush 5. The rear side of the roller brush cover 22 has a docking interface 222 that connects to the front air duct 221 and is connected to the switching mechanism 3. The second suction port 26 is close to the wall and draws dirt into the docking channel 27 through the front air duct 221 and then into the suction channel to reach the suction device. Furthermore, the length of the second suction port 26 is greater than or equal to the length of the floor cleaning roller brush 5 to expand the suction area and facilitate the suction of dirt from the floor. The two side walls of the front air duct 221 slope and narrow towards the center and connect to the docking interface 222. Figure 7 As shown, this facilitates the collection and efficient removal of dirt and debris from the front air duct 221.

The flipping device includes an electromagnetic drive rod 34 and a drive plate 35. The flipping baffle 33 is rotatably connected to the docking channel 27 via a rotating shaft 36 and is located between the first guide port 311 and the second guide port 321. The rotating shaft 36 has an extension section extending into the floor brush housing 21. The drive plate 35 is arranged on the extension section. The electromagnetic drive rod 34 pushes the drive plate 35 via a telescopic push rod 341, thereby pushing the flipping baffle 33 to rotate and back and forth between the first guide port 311 and the second guide port 321. Specifically, the first guide pipe 31 and the second guide pipe 32 are arranged vertically. The flipping baffle 33 flips vertically via the rotating shaft 36. The electromagnetic drive rod 34 is arranged below the rotating shaft 36. The push rod 341 of the electromagnetic drive rod 34 extends and pushes the drive plate 35 to make the flipping baffle 33 rotate upward to block the second guide port 321. The push rod 341 of the electromagnetic drive rod 34 retracts, and the flipping baffle 33 and the drive plate 35 flip downward under the action of gravity to block the first guide port 311. More preferably, a reset torsion spring 37 may also be provided on the rotating shaft 36, and the flipping baffle 33 is kept in the state of sealing the first conduction port 311 under the action of the reset torsion spring 37.
