Description

Technical Field

[0001] This invention relates to an improvement of floor brushes, specifically a floor brush with a rotating body that can be locked upright, and the locking is more stable, less prone to loosening, and has a longer lifespan. Background Technology

[0002] A floor brush is a standard feature of vacuum cleaners. The main body of the vacuum cleaner generates a vacuum source, while the floor brush cleans the surface. The main body and the floor brush are connected. The negative pressure generated by the vacuum source sucks away the dust and dirt swept up from the surface by the floor brush. After filtration, the dust is stored in a dustbin inside the main body of the vacuum cleaner. Typically, the floor brush body is connected to a rotary joint via a flexible hose. The lower part of the rotary joint is rotatably connected to a rotating body. The rotating body is rotatably mounted on the floor brush body and is hollow. The flexible hose passes through the rotating body. The main body of the vacuum cleaner is connected to the upper part of the rotary joint via a rigid tube, achieving internal communication. The rotation directions of the rotating body and the rotary joint are perpendicular to each other. A rotating shaft is horizontally positioned at the lower end of the rotating body. Long, rectangular locking blocks are correspondingly positioned on the circumferential surfaces at both ends of the rotating shaft. The locking blocks are parallel to the axis of the rotating shaft. The rotating shaft is rotatably... It is installed inside the sleeve of the floor brush body; the inside of the sleeve is provided with a long strip-shaped locking groove; the locking groove is arranged parallel to the axis of the rotating shaft; in normal use, rotating the rotating shaft causes the locking block to be inserted into the locking groove, the rotating body is in a vertical state and locked; rotating the rotating shaft again causes the free end of the rotating body to rotate towards the original position away from the floor brush body, the locking block will rotate out of the locking groove, at this time, the rotating body is in a free rotation state, so that the user can hold the hand part provided on the rigid tube or the vacuum cleaner body to work without bending over, and at the same time the lower surface of the floor brush body is always in contact with the surface being cleaned.

[0003] This method of vertically locking the rotating body by the hard engagement of the locking block and the locking groove will cause damage to the friction surfaces of the locking block and the locking groove as the usage time increases. The hard engagement between the locking block and the locking groove will gradually become loose, until the locking block is inserted into the locking groove but cannot achieve locking.

[0004] To address this, we developed a rotating body vertical locking floor brush that offers more stable locking, is less prone to loosening, and has a longer lifespan. Summary of the Invention

Elongated locking blocks 22 are correspondingly arranged on the circumferential surface; the locking blocks 22 are arranged parallel to the axis of the first rotating shaft 21; rotating blocks 3 are respectively arranged on both sides of the rear end of the floor brush body 1; the rotating blocks 3 are arranged parallel to each other; the rotating blocks 3 are arranged in a stepped shape, with their rotating end 31 located at the lower free end, the rotating end 31 being horizontally arranged with a second rotating shaft 33, and their reset end 32 located at the upper free end, the upper surface of the reset end 32 being vertically arranged with a through hole 34; a locking protrusion 35 is horizontally arranged in the middle of the upper surface of the rotating block 3; the rotating end 31 is located near the rear end of the floor brush body 1, and the reset end 32 is located away from the rear end of the floor brush body 1; the second rotating shaft 33 The reset end 32 is installed inside the brush body 1 and can rotate around the corresponding second rotating axis 33. A locking screw 5 is installed in the through hole 34. A reset spring 4 is sleeved on the locking screw 5. The locking screw 5 is vertically arranged to lock the corresponding reset end 32 inside the brush body 1. The reset spring 4 is located between the corresponding brush body 1 and the rotating block 3 to reset the reset end 32. The locking protrusion 35 is parallel to the axis of the first rotating axis 21. The second rotating axis 33 is parallel to the axis of the first rotating axis 21. The two ends of the first rotating axis 21 are respectively set on the corresponding rotating blocks 3. When the first rotating axis 21 rotates, and the locking block 22 is located between the corresponding locking protrusion 35 and the second rotating axis 33, the lock is activated. When the locking block 22 contacts the corresponding locking protrusion 35, the rotating body 2 is in an upright state, and at the same time, the front end of the rotating body 2 contacts the floor brush body 1, preventing the rotating body 2 from continuing to move towards the front end of the floor brush body 1; at this time, the rotating body 2 is in an upright locked state; when the first rotating shaft 21 is rotated in the opposite direction, causing the upper end of the rotating body 2 to move away from the front end of the floor brush body 1, the locking block 22 will press the corresponding locking protrusion 35, causing its corresponding reset end 32 to descend until the locking block 22 flips over the corresponding locking protrusion 35.

The user holds the handle on the rigid tube or vacuum cleaner body connected to the rotary joint 6 and works without bending over. At the same time, the lower surface of the floor brush body is always in contact with the surface being cleaned. When the first rotating shaft 21 is rotated so that the upper end of the rotating body 2 moves toward the front end of the floor brush body 1, when the locking block 22 contacts the corresponding locking protrusion 35, the locking block 22 will press against the corresponding locking protrusion 35, causing the corresponding reset end 32 to descend until the locking block 22 flips over. After the locking block 22 passes the corresponding locking protrusion 35, the corresponding reset end 32 automatically resets under the action of the corresponding reset spring 4. At this time, the rotating body 2 is in an upright state, and the front end of the rotating body 2 contacts the floor brush body 1, preventing the rotating body 2 from continuing to move towards the front end of the floor brush body 1. At this time, the rotating body 2 is in an upright locked state. By rotating the first rotating shaft 21 in the opposite direction, the rotating body 2 can be converted from the upright locked state to a free rotation state. By repeating this process, the free conversion of the rotating body 2 from the upright locked state to the free rotation state can be achieved.

When the locking block 22 is located between the locking protrusion 35 and the corresponding reset end 32, the rotating body 2 is in a free rotation state. When the locking block 22 is located between the locking protrusion 35 and the corresponding second rotating shaft 33, and the locking block 22 is in contact with the corresponding locking protrusion 35... When touched, the rotating body 2 is in an upright state, and at the same time, the front end of the rotating body 2 contacts the floor brush body 1, preventing the rotating body 2 from continuing to move towards the front end of the floor brush body 1; at this time, the rotating body 2 is in an upright locked state; by repeatedly rotating the first rotating shaft 21, the rotating body 2 can be freely switched from the upright locked state to the free rotation state; the friction between the locking block 22 and the locking protrusion 35 of the floor brush with the rotating body of the present invention is small, and the wear of the locking block 22 and the locking protrusion 35 is also small during operation, so its service life can be longer.
