Description

Technical Field

[0001] The present invention relates to the technical field of vacuum cleaner floor brushes, and in particular to a corner scrubbing structure of a vacuum cleaner floor brush. Background Art

[0002] A vacuum cleaner is a widely used cleaning device. The working principle of a vacuum cleaner is to drive the blades to rotate at high speed by an electric motor, generate air negative pressure in a sealed housing, and then suck dust through an external suction pipe.

[0003] When a vacuum cleaner cleans the ground through a floor brush, negative pressure is generated at the air inlet on the bottom surface of the floor brush to suck and clean the dust on the ground. However, when the floor brush cleans the bottom surface at the corner of a wall, the floor brush cannot clean the skirting board at the bottom of the wall, but instead will scrape and collide with the skirting board, causing damage. In addition, when the floor brush cleans a special floor area such as the ground at the stair railing, due to the obstruction of the railing, the floor brush cannot clean the area between the railings and the area of the ground beyond the railing. Summary of the Invention

Obviously, the described embodiments are some but not all of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0033] Please refer to Figures 1 - 7, the present invention provides a technical solution: a corner scrubbing structure for a vacuum cleaner floor brush, including: a floor brush upper cover 1, a scrubbing cloth rod 2, a scrubbing cloth bracket 3, and a scrubbing cloth 4. A receiving groove 11 matching the shape of the scrubbing cloth rod 2 is provided on the floor brush upper cover 1. The scrubbing cloth rod 2 includes a vertical rod body 21 and a horizontal rod body 22. The horizontal rod body 22 is perpendicular to the vertical rod body 21. The vertical rod body 21 is rotatably installed in the receiving groove 11. The scrubbing cloth bracket 3 is detachably installed on the scrubbing cloth rod 2. A scrubbing cloth mounting plate 31 is provided at the end of the scrubbing cloth bracket 3. The scrubbing cloth 4 is detachably installed on the scrubbing cloth mounting plate 31.

[0034] The back of the scrubbing cloth 4 is adhered to the scrubbing cloth mounting plate 31 by Velcro, which is convenient for removing the scrubbing cloth 4 for cleaning.

[0035] The horizontal rod body 22 is inserted into the slot at the end of the scrubbing cloth bracket 3 to achieve the disassembly and replacement of the scrubbing cloth bracket 3.

[0036] Scrubbing cloth bracket 3, solution one: The scrubbing cloth bracket 3 is a horizontal scrubbing cloth bracket 34. The scrubbing cloth mounting plate 31 is fixedly installed at the end of the horizontal scrubbing cloth bracket 34. The scrubbing cloth mounting plate 31 is perpendicular to the horizontal rod body 22.

[0037] Scrubbing cloth bracket 3, solution two: The scrubbing cloth bracket 3 is a floor scrubbing cloth bracket 35. The structure of the floor scrubbing cloth bracket 35 is in an "L" shape. The scrubbing cloth mounting plate 31 is fixedly installed at the end of the floor scrubbing cloth bracket 35. The scrubbing cloth mounting plate 31 is parallel to the horizontal rod body 22.

[0038] A receiving locking component 5 is provided on the floor brush upper cover 1. The receiving locking component 5 includes an electromagnet 51 and a first locking block 52. The first locking block 52 is elastically connected to the floor brush upper cover 1. The first locking tongue 521 of the first locking block 52 passes through the shell of the floor brush upper cover 1 and is inserted into the blind hole 211 of the vertical rod body 21. The electromagnet 51 is used to adsorb the first locking block 52. The electromagnet 51 is connected to the power supply through a power supply circuit. A power-off delay relay and a control switch are provided in series with the electromagnet 51 on the power supply circuit. An unfolding locking component 6 is also provided on the floor brush upper cover 1. The unfolding locking component 6 includes a control board 61, a first bolt 62, and a second bolt 63. The control board 61 is elastically connected to the floor brush upper cover 1. The first bolt 62 and the second bolt 63 are symmetrically arranged on both sides of the control board 61. The position of the first bolt 62 corresponds to the vertical rod body 21. The first bolt 62 passes through the bottom surface of the receiving groove 11 and is inserted into the blind hole 211. The second bolt 63 passes through the bottom surface of the receiving groove 11 and abuts against the horizontal rod body 22.

[0039] When the wiping rod 2 is stored in the storage slot 11, the storage locking assembly 5 locks the position of the wiping rod 2. At this time, the electromagnet 51 is not energized, and the first locking block 52 maintains the first locking tongue 521 plugged into the blind hole 211 on the vertical rod body 21 under the elastic force of the elastic element, locking the position of the wiping rod 2 to prevent the wiping rod 2 from leaving the storage slot 11. At this time, the first latch 62 and the second latch 63 are against the side of the wiping rod 2, the control board 61 is in a position away from the wiping rod 2, and the elastic element between the control board 61 and the floor brush upper cover 1 is in a stretched state.

[0040] When the wiping rod 2 needs to be used, the control switch is triggered once to turn on the power supply circuit of the electromagnet 51, so that the electromagnet 51 generates magnetic force, sucking the first locking block 52 away from the wiping rod 2, so that the first locking tongue 521 is separated from the wiping rod 2, and the wiping rod 2 can be rotated to open. At the same time, due to the setting of the power-off delay relay on the power supply circuit, the power supply circuit is powered on for a period of time (such as setting a delay of 15 seconds) and the power is delayed by the power-off delay relay. The electromagnet 51 no longer absorbs the first locking block 52, and the first locking tongue 521 is held by the wiping rod 2 and cannot be extended into the storage slot 11. In this way, when the wiping rod 2 is rotated and stored, there is no need to control the switch again. It is only necessary to rotate the blind hole 211 on the wiping rod 2 to align with the first latch 62 to automatically lock the wiping rod 2, thereby simplifying the locking process of the wiping rod 2.

[0041] The blind hole 211 on the unfolded wiping rod 2 is aligned with the first latch 62, and the first latch 62 is inserted into the blind hole 211 under the drive of the control board 61. The first latch 62 positions the wiping rod 2 to prevent the position of the wiping rod 2 from changing during the cleaning process. At the same time, the second latch 63 extends out of the bottom surface of the storage slot 11. When the wiping rod 2 is rotated and stored, the second latch 63 can be pressed to drive the control board 61 away from the wiping rod 2, so that the first latch 62 is disengaged from the blind hole 211. Then the wiping rod 2 can be rotated.

[0042] During the operation of the wiping cloth bracket 3, the wiping cloth rod 2 is fully locked whether in a folded storage state or a rotated open state, so as to be convenient for use.

[0043] Working principle: When using the vacuum cleaner floor brush, if you need to wipe the dust off special areas such as the corners of the wall while cleaning the dust on the floor, you can rotate and take out the wiping rod 2 so that the cross bar 22 of the wiping rod 2 extends out of the storage slot 11, and then you can install the wiping bracket 3. After that, use the wiping cloth 4 at the end of the wiping bracket 3 for cleaning. Specifically, when the floor brush needs to additionally clean the dust at the corners of the wall (such as the skirting), the wiping cloth bracket 3 uses a horizontal wiping cloth bracket 34. While the vacuum cleaner floor brush cleans the floor, the wiping cloth 4 at the end of the horizontal wiping cloth bracket 34 cleans the skirting. The principle can be seen in the attached figure. Figures 1 - 2When the floor brush needs to clean the dust on the ground beyond the railing of the stairs additionally, the cloth holder 3 adopts the floor cloth holder 35. While cleaning the ground with the floor brush of the vacuum cleaner, the floor cloth holder 35 extends out of the railing and cleans the ground beyond the railing with the cloth 4 at its bottom. For the principle, please refer to the appendix Figures 3 - 4 。
