Description

Technical Field

[0001] The invention relates to the technical field of floor brushes, in particular to a floor brush roller dust suction structure. Background Art

[0002] A floor brush refers to a rotating brush head at the bottom of a vacuum cleaner, which is mainly used to clean hard floors and carpets. It can effectively remove dust and debris on the floor. It is mainly suitable for hard floors and low-density carpets, such as wooden floors, tiles, marble, etc. During the rotating cleaning process of the existing floor brush roller, there is a dead angle between the circular roller and the right-angled floor, making it difficult to effectively clean with the floor brush. ‌‌ The invention with announcement number CN115633912A discloses a floor brush capable of cleaning without dead angles. Through the cooperation of a follower wheel, a roller brush and an electrostatic strip, the floor brush capable of cleaning without dead angles can clean all the areas it passes through at one time during the movement. It is very convenient especially when cleaning the corners of a house, and can clean all the areas at one time without dead angles.

[0003] The utility model with announcement number CN215584061U discloses a cleaning tool floor brush with a dead-angle cleaning function. A side roller brush is arranged on the outside of the main roller brush, and the side roller brush is placed on the outside of the cover shell of the floor brush body. The side roller brush can be used to remove dust, mop the floor and clean dead corners such as wall corners, so that the floor mop has a dead-angle cleaning function; at the same time, at least one group of self-rotating scrapers is provided, which can actively comb the main roller brush.

[0004] However, the above-mentioned floor brush with no dead angle cleaning still has the following problems during actual use: although cleaning is achieved by setting a brush strip for contacting the dead angle at the front end of the floor brush, it is difficult for such a cleaning strip to move the floor brush laterally along the vertical wall when in use, and only multiple, reciprocating cleaning can be achieved. There is no corresponding cleaning brush component on the side of the floor brush, and the cleaning brush mechanism also has no corresponding dust suction mechanism. After the dead angle cleaning operation is completed, it is difficult to drive the dirt to be transported to the floor brush, resulting in residual dirt.

[0005] Therefore, we propose a floor brush roller dust suction structure to solve the above-mentioned problems. Summary of the invention

[0006] The purpose of the present invention is to provide a floor brush roller dust suction structure, in order to solve the problem that a brush strip for contacting dead corners is arranged at the front end of the existing floor brush to achieve cleaning, but such cleaning strip is difficult to make the floor brush move horizontally along the vertical wall when in use, and can only achieve multiple, reciprocating cleaning. There is no corresponding cleaning brush component on the side of the floor brush, and the cleaning brush mechanism also has no corresponding dust suction mechanism. After completing the cleaning operation of the dead corner, it is difficult to drive the dirt to be transported to the floor brush, resulting in the problem of residual dirt.

[0009] Preferably, the floor brush mechanism includes cleaning scraping strips for cleaning vertical walls, and the cleaning scraping strips are fixedly distributed at equal angles on the outer walls of the auxiliary roller brush and the side wall roller brush, and the cleaning scraping strips under the auxiliary roller brush and the side wall roller brush are in contact with the ground.

[0010] Preferably, the auxiliary roller brush included in the floor brush mechanism is meshedly connected to the outer end rotating shaft of the floor roller brush through a sprocket mechanism, and the floor roller brush is driven by a motor built into the floor brush body, and the bottom surface height of the floor roller brush is lower than the bottom surface height of the floor brush body.

[0011] Preferably, the dust suction mechanism comprises three main dust suction windows at equal distances at the front end of the dust suction duct, and the main dust suction windows and auxiliary dust suction windows on the left and right sides of the front end of the dust suction duct are interconnected.

[0012] Preferably, the dust suction mechanism includes a rotating shaft, and the rotating shaft is rotatably arranged at the front end and left and right sides of the dust suction duct through a torsion spring, and closed flip plates are fixedly arranged on the outer walls of the main dust suction window and the auxiliary dust suction window of the rotating shaft.

[0016] Preferably, the outer end of the main contact slide plate in front of the contact plate protrudes from the outer end of the cleaning scraper strip in front of the auxiliary roller brush, and the outer ends of the auxiliary contact slide plates on the left and right sides of the contact plate protrude from the outer ends of the side wall roller brushes.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the floor brush roller dust suction structure, through the main contact slide plate and the auxiliary contact slide plate protruding from the front end and the side of the floor brush body, opens the corresponding main dust suction window and the auxiliary dust suction window during the cleaning of the dead corner by the auxiliary roller brush and the side wall roller brush, and assists in the suction and recovery of the debris during the cleaning of the dead corner, so as to improve the suction force and the efficiency of the dirt removal during the dust collection process, and the specific contents are as follows: 1. The motor inside the floor brush body drives the floor roller brush to rotate, and the floor roller brush drives the auxiliary roller brush at the front end to rotate synchronously through the sprocket mechanism at the outer end. At the same time, the auxiliary roller brush contacts the ground through the cleaning scraper strips set at equal angles on the outside, thereby assisting the floor roller brush in contact with the ground to perform cleaning work.

[0019] 2. The main resistance slide plate at the front end of the floor brush body contacts the wall and squeezes it to move backward along the resistance plate. At the same time, the fixed traction cable is tensioned, so that the traction cable drives the rotating shaft rod wound at the upper end to rotate inside the dust collection duct, and then drives the closed flip plates set at equal distances to rotate 90°, so as to open the originally closed main dust collection window, and then absorb the scraped dirt and dust, and transport them to the dust collecting bin inside the floor brush body.

[0020] 3. Use the side wall roller brush and the cleaning scraper to clean the debris. At the same time, the auxiliary contact slide plate contacts the wall and slides to the inside of the contact plate, driving the traction cable to drive the rotating shaft and the closed flip plate to rotate, so that the closed auxiliary dust suction window is opened, and then the debris scraped by the side wall roller brush and the cleaning scraper is absorbed into the dust collecting bin through the side auxiliary dust suction window to avoid dust and cleaning residues.

[0021] The opened auxiliary dust suction window is connected to the main dust suction window on the corresponding side, and the other main dust suction windows are in a closed state, so that the negative pressure inside the floor brush body and the dust suction duct is concentrated in the corresponding opened auxiliary dust suction window and the main dust suction window, so as to improve the suction force and dirt removal efficiency during the dust collection process.
