Technical Field

[0001] The present invention relates to the technical field of cleaning mechanisms for floor sweepers, and particularly to a cleaning mechanism for a floor sweeper that is convenient to fold and its usage method. Background Art

[0002] A floor sweeper refers to a floor cleaning robot, which is an essential cleaning assistant in the family. A floor cleaning robot is a type of intelligent household appliance that can automatically complete the floor cleaning work in a room by virtue of a certain degree of artificial intelligence. By using the cleaning mechanism of the floor cleaning robot, the sundries on the ground are swept and sucked into its own garbage collection box, thus completing the function of floor cleaning.

[0003] The defects of the existing cleaning mechanisms for floor sweepers are as follows:

[0004] 1. Patent document CN113812887A discloses an opposing brush cleaning mechanism for an intelligent floor cleaning robot, "including a housing, a straight brush is arranged on the front side of the bottom of the housing, three - leaf brushes are arranged on both sides of the straight brush, a dust collection port is arranged behind the straight brush, a dust - blocking plate is arranged on the inner wall of the dust collection port, an air suction port is arranged on the inner side of the dust - blocking plate away from the dust - blocking plate, a dust collection box is arranged behind the dust collection port, rollers are arranged on both sides of the dust collection box, power boxes are arranged on both sides of the dust collection port, drive hubs are arranged at the ends of the power boxes, two planetary gears are symmetrically arranged on the inner side of the drive hubs, and a direction - changing wheel is meshed and connected to the outer side of the planetary gears away from the dust collection port. In the opposing brush cleaning mechanism of the intelligent floor cleaning robot, the drive hub drives the direction - changing wheel and the opposing wheel to rotate synchronously, and at the same time, the inner shaft controls the alternating opening and closing of the row brush. While the brush removes stubborn dirt, it constantly opens and closes to prevent being entangled by filaments such as hair." In the opposing brush cleaning mechanism of the intelligent floor cleaning robot in the above - mentioned published document, it mainly considers how to constantly open and close to prevent being entangled by filaments such as hair while the brush removes stubborn dirt. When this device is cleaning, the cleaning range of the cleaning brush is small, which easily leads to the technical problem of poor cleaning effect;

[0005] 2. Patent document CN213488623U discloses a cleaning mechanism for an intelligent floor sweeper, "including an anti-collision housing, a camera sensor, and an air outlet. The anti-collision housing is a cylindrical outer ring fixedly installed with a camera sensor, and the anti-collision housing is grooved and installed with an air outlet. The beneficial effects achieved by the present invention are: The structure of the present invention is compact and the function is practical. On the basis of the original, the present invention adds a baking lamp, which can realize cleaning and mopping. After mopping, the excess water is removed through the baking lamp, making the area after work clean and tidy without residual water stains. The clean and dry ground has a certain anti-slip effect. The inhaled dust and debris will be centrally collected in the dust collection box, and the filtered gas will be discharged through the air outlet." For the cleaning mechanism of the intelligent floor sweeper in the above-mentioned published document, it mainly considers how the inhaled dust and debris will be centrally collected in the dust collection box, and the filtered gas will be discharged through the air outlet. After the device sucks dust, the filtered gas is directly discharged, and the filtered gas cannot be reused, which is likely to cause the technical problem of waste of resources;

The body includes a suction fan, a collection component, a sensor, two cleaning components, and two universal wheels. The cleaning component includes a positioning block, a first motor, and a dust collecting brush. The first motor is fixedly connected to the positioning block, and the dust collecting brush is connected to the output shaft of the first motor. The body is fixedly provided with a second motor, and the output shaft of the second motor is fixedly connected with a threaded rod. The end of the threaded rod away from the second motor is rotatably connected to the body. The thread directions at both ends of the threaded rod are opposite, and the two positioning blocks are respectively threadedly connected to both ends of the threaded rod. The body is provided with a limiting groove adapted to the positioning block. The second motor drives the threaded rod to move the two positioning blocks towards each other, and then the distance between the two dust collecting brushes is reduced, and then the two dust collecting brushes rotate in opposite directions for cleaning, and the garbage located in the middle position between the two dust collecting brushes is cleaned into the collection component, and the cleaning effect on the garbage is better." For the cleaning mechanism of the household floor sweeping robot in the above-mentioned published document, it mainly considers how to clean the garbage located in the middle position between the two dust collecting brushes into the collection component, and the cleaning effect on the garbage is better. During the use of the device, it is difficult to handle the impurities or pigments stuck to the ground;

Then, the second motor 202 drives the transmission rod 203, the rotating disk 204 and the brush 205 to rotate, thereby improving the cleaning range and cleaning efficiency. Through the settings of the fourth rotating shaft 501, the torsion spring 502 and the limiting plate 503, the dust suction fan 304 rotates to generate suction force. The generated suction force can pull one end of the limiting plate 503. Then, through the setting of the dust suction hole 402, the dust suction treatment of the ground can be completed. Through the dust-proof filter screen 303, the situation that the inhaled garbage is discharged from the exhaust duct 302 can be avoided. And when not in use, the limiting plate 503 can seal one end of the dust suction hole 402 to avoid the situation that garbage is discharged from the dust suction hole 402. Through the settings of the exhaust duct 302 and the trapezoidal exhaust nozzle 801, the discharged air can be discharged from the trapezoidal exhaust nozzle 801, thereby drying the ground wiped by the rag 707 and improving the cleaning efficiency. Through the settings of the water inlet pipe 602 and the sealing plug 603, it is convenient to add cleaning liquid into the water tank 601. The water pump 604 transports the water in the water tank 601 through the water suction pipe 605 to the spray pipe 606 and sprays it out through the atomizing nozzle 607, thereby completing the spraying treatment of the ground. Then, through the setting of the rag 707, it is convenient to clean the impurities or pigments adhered to the ground and improve the cleaning effect. By pulling the pull rod 708 to drive the limiting block 705 to move in the limiting groove 703, the limiting block 705 is separated from the inside of the limiting hole 706. At this time, the fixing plate 702 can be taken out from the fixing sleeve 701, thereby facilitating the replacement of the rag 707 with dirty surface, and then improving the cleaning efficiency by quickly replacing the clean rag 707.
