Technical Field

[0001] The invention relates to the technical field of sweeping machines, and in particular to a sweeping machine floor brush with an anti-winding and high-efficiency cleaning mechanism. Background Art

[0002] The household sweeper is a wireless machine that uses a rechargeable battery and is operated by a remote control or the operation panel on the machine. It can take different cleaning routes and plan the cleaning areas. Due to its simple operation function and convenience, it has gradually become popular and has become a common household appliance for office workers or modern families.

[0003] When the sweeper is working, the roller brush body rotates on the ground, and the brushes and cloth strips on the roller brush body adhere to the garbage to clean the ground, and then the garbage on the brushes and cloth strips is sucked away by high-speed airflow; however, there will be some hair in the garbage, and the hair is easily entangled on the brushes and cloth strips. It is difficult for traditional sweepers to clean the hair entangled on the brushes and cloth strips by suction, and it is also difficult to clean the entangled hair during daily manual maintenance, and the cleaning efficiency is low. After long-term use, the hair on the brushes and cloth strips becomes more and more, which will reduce the subsequent cleaning efficiency of the sweeper, and it is also easy to cause the roller brush body to get stuck, shortening the service life of the sweeper.

[0014] Compared with the prior art, the present invention has the following advantages: 1. The telescopic rod of the electric push rod contracts and drives the rack rack to move in the direction away from the bent pipe, the rack rack drives the vertical gear to rotate, thereby driving the hollow drum to rotate, and the hollow drum drives the scraper rod and the connecting plate to make circular motion. The torsion spring is twisted, and the connecting plate is squeezed by the arc groove on the arc groove fixed plate during the rotation process, so that the connecting plate moves in the direction away from the center of the arc groove fixed plate, and the connecting plate drives a plurality of scraper rods to move, so that the plurality of scraper rods extend out of the hollow drum, and at the same time, the hollow drum drives the plurality of scraper rods to rotate until they are gradually close to the center of the arc groove fixed plate. The roller brush body, brush strips and cloth strips enable a plurality of scraper rods to scrape the brush strips and cloth strips, thereby cleaning the hair entangled on the surfaces of the brush strips and cloth strips, making it easier for the brush strips and cloth strips to clean the garbage adsorbed on the ground. Then the rack frame continues to move and disengages from the vertical gear, the torsion spring quickly resets and drives the hollow drum to rotate in the opposite direction, and a plurality of scraper rods retract into the hollow drum, so that the hair can be cleaned when it is needed, and the scraper rod will not be close to the cloth strips and brushes when it is not needed, so as to reduce the wear on the scraper rods, cloth strips and brushes and extend their service life.

[0015] 2. When the telescopic rod of the electric push rod is extended and retracted and drives the rack rack to move back and forth, the offset rack will intermittently disengage or engage with the column gear, so that the offset rack drives the column gear to intermittently reciprocate, and the column gear drives the toggle plate to swing back and forth intermittently, so that the toggle plate cleans the scraper rod, so that the scraper rod can scrape the hair on the cloth strip and the brush strip more efficiently.

[0016] 3. Initially, the wind-blocking iron plate blocks the connection between the upper part of the double-mouth suction pipe and the connecting pipe, and the suction port at the lower part of the double-mouth suction pipe has a greater suction force to absorb the garbage on the ground; when the telescopic rod of the electric push rod contracts and drives the rack frame to move away from the bent pipe, the rack frame drives the driving slot frame to move away from the bent pipe, and the driving slot frame squeezes the roller to move downward, and the roller drives the magnet frame to move downward, and the magnet frame drives the wind-blocking iron plate to move downward through magnetic force, so that the wind-blocking iron plate blocks the connection between the lower part of the double-mouth suction pipe and the connecting pipe, thereby stopping the suction port at the lower part of the double-mouth suction pipe from sucking air, and then concentrating the wind force on the suction port at the upper part of the double-mouth suction pipe, allowing the double-mouth suction pipe to absorb the hair scraped out by the scraper rod with greater suction force, and cleaning the scraper rod more thoroughly.

Two electric push rods 83 are fixedly connected to the top of the shell 1. The electric push rods 83 are horizontally arranged. A rack rack 84 is fixedly connected between the telescopic rods of the two electric push rods 83, and the rack rack 84 is meshed with the two vertical gears 82 at the same time.

[0039] When the sweeper is working, the roller brush body 3 rotates on the ground, and the roller brush body 3 drives the brush strips 32 and the cloth strips 31 to rotate, thereby cleaning the ground. The garbage on the ground adheres to the brush strips 32 and the cloth strips 31, and the dust-absorbing wind passes through the curved pipe 6, the connecting pipe 5 and the double-mouth suction pipe 4, so that the double-mouth suction pipe 4 absorbs dust through the suction port at the bottom, thereby sucking away the garbage on the brush strips 32 and the cloth strips 31. There are some hairs in the garbage that are easily entangled on the brush strips 32 and the cloth strips 31. When it is necessary to clean the hairs on the brush strips 32 and the cloth strips 31, the user starts the electric push rod 83, and the telescopic rod of the electric push rod 83 contracts and drives the rack The rack 84 moves in the direction away from the curved pipe 6, the rack rack 84 will drive the vertical gear 82 to rotate, the vertical gear 82 will drive the overrunning clutch 81 and the hollow drum 72 to rotate, the hollow drum 72 will drive the scraper rod 74 and the connecting plate 75 to make a circular motion, the torsion spring 73 will be twisted, and the connecting plate 75 will be squeezed by the arc groove on the arc groove fixed plate 76 during the rotation process, so that the connecting plate 75 moves in the direction away from the center of the arc groove fixed plate 76, and the connecting plate 75 will drive a plurality of scraper rods 74 to move, so that a plurality of scraper rods 74 extend out from the hollow drum 72, and at the same time, the hollow drum 72 drives a plurality of scraper rods 74 to rotate until they are gradually close to each other.
