[0004] Regarding the above-mentioned related technologies, there are the following technical defects: when using a vacuum cleaner for cleaning, since the connection between the floor brush housing and the vacuum cleaner is relatively fixed, it is inconvenient for the vacuum cleaner to clean the dust in corners or gaps. Summary of the Invention

[0005] In order to facilitate the cleaning of dust in corners or gaps, the present application provides a multi-dimensional automatic reset floor brush.

[0006] The multi-dimensional automatic reset floor brush provided in this application adopts the following technical solution:

[0007] A multi-dimensional automatic reset floor brush comprises a connecting rod mounted on a vacuum cleaner and a floor brush housing;

[0008] The connecting rod is a hollow structure, one end of the connecting rod is connected to the vacuum cleaner, and the other end is rotatably connected to the floor brush housing;

[0009] A first dust suction port is provided on a side of the floor brush housing away from the connecting rod, and the first dust suction port is communicated with the connecting rod.

[0010] By adopting the above technical solution, the floor brush shell is brought close to the cleaning place, the first dust suction port is facing the dust and impurities in the cleaning place, the vacuum cleaner is turned on, and negative pressure is generated in the vacuum cleaner. Under the action of negative pressure, the dust in the cleaning place enters the vacuum cleaner through the first dust suction port, thereby cleaning the dust in the cleaning place. In the process of cleaning the cleaning place, the connecting rod is continuously swung, and the movement of the connecting rod drives the movement of the floor brush shell, thereby achieving comprehensive cleaning of the cleaning place. When cleaning the corners or gaps in the cleaning place, the floor brush shell is pressed against the cleaning place, the floor brush shell receives the pressing force, and the floor brush shell and the connecting rod rotate relative to each other, making it easier for the first dust suction port to approach the corners or gaps of the cleaning place, thereby facilitating the cleaning of the corners or gaps in the cleaning place.

[0011] Optionally, the connecting rod includes a first connecting section, a second connecting section and a third connecting section;

[0012] One end of the first connecting section is connected to a vacuum cleaner;

[0013] One end of the second connecting section is rotatably connected to the other end of the first connecting section, and the second connecting section is capable of rotating around the axis of the first connecting section;

[0014] The third connecting segment is rotatably connected to the other end of the second connecting segment, and the axis of rotation of the third connecting segment is perpendicular to the axis of the second connecting segment;

[0015] The other end of the third connecting section is rotatably connected to the floor brush housing.

[0016] By adopting the above technical solution, when cleaning the gaps in the cleaning place, the second connecting section is rotated, the second connecting section drives the third connecting section to rotate, the third connecting section drives the floor brush shell to move, and the floor brush shell changes state, so that the floor brush shell can extend into the gap, which is convenient for cleaning the dust in the cleaning place. At the same time, the second connecting section is rotated, so that the cleaning personnel only needs to stand in a fixed position to clean the gap, reducing the need for personnel to move.

[0017] Optionally, it further includes a reset component for driving the floor brush housing to return;

[0018] The reset assembly includes a rotating block, a moving block and a reset spring;

[0019] The rotating block is provided at the end of the third connecting section, the floor brush housing is provided with a rotating groove, the rotating block extends into the rotating groove, and the rotating block is rotatably connected to the floor brush housing;

[0020] The moving block is arranged on the rotating block;

[0021] The return spring is arranged in the rotating groove and applies force to the floor brush housing. Under the action of the return spring, the rotating block and the floor brush housing move relative to each other, and the force of the floor brush housing is removed. Under the action of the return spring, the floor brush housing returns to its original position.

[0022] By adopting the above technical solution, when cleaning the corners or gaps in the cleaning place, the floor brush shell receives external force and the floor brush can rotate relative to the third connecting section. The rotation of the floor brush shell drives the rotating block to move, and the movement of the rotating block drives the moving block to move. The moving block contacts the reset spring and the spring contracts. When the external force is removed, the reset spring tends to stretch. The stretching of the reset spring drives the moving block to move, and the movement of the moving block drives the rotating block to move. The movement of the rotating block drives the floor brush shell to move, and the floor brush shell generates a restoring force, and the floor brush shell returns to its original state. On the one hand, it reduces the steps of regularly placing the floor brush shells for later storage, thereby improving the use efficiency. On the other hand, it is convenient for the subsequent cleaning of other cleaning places without the need for manual swinging, thereby further improving the use efficiency.

[0023] Optionally, it further comprises a first limiting block and a second limiting block for limiting the movement of the return spring;

[0024] The first limiting block is connected to the side wall of the rotation groove;

[0025] The second limiting block is connected to the side wall of the rotation groove, and the first limiting block and the second limiting block form a limiting space for limiting the movement of the return spring.

[0026] By adopting the above technical solution, the first limiting block and the second limiting block are set to limit the reset spring to a certain range, reducing the phenomenon of irregular movement of the reset spring during the rotation of the crust brush body, and improving the rotation stability between the crust brush body and the third connecting section.

[0027] Optionally, the first limiting block is provided with a first reset channel for the movement block to pass through, and the first limiting block is slidably connected to the movement block;

[0028] The second limiting block is provided with a second reset channel for the movement block to pass through, and the second limiting block is slidably connected to the movement block;

[0029] The first reset channel is connected to the second reset channel.

[0030] By adopting the above technical solution, when the crust brush body and the third connecting section rotate, the moving block passes through the first reset channel, the moving block contacts the reset spring, and the reset spring is compressed. At this time, the other moving block is away from the second limiting block, and the floor brush shell rotates. When the reset spring rebounds, the reset spring drives the moving block to move, the moving block drives the rotating block to move, and the rotating block drives the floor brush shell to move, and the floor brush shell returns to its original position.

[0031] Optionally, a cleaning component for cleaning large impurities is also included;

[0032] The cleaning component includes cleaning bristles and a cleaning brush plate;

[0033] The cleaning bristles are detachably mounted on the floor brush housing, and the cleaning bristles are symmetrically arranged with respect to the length direction of the floor brush housing;

[0034] The cleaning brush plate is arranged on the floor brush housing, and is used for scraping off large impurities.

[0035] By adopting the above technical solution, when there are large impurities in the cleaning place, the connecting rod is moved, and the connecting rod drives the floor brush shell to move, and the movement of the floor brush shell drives the cleaning brush plate to move, and the cleaning brush plate scrapes off the larger impurities in the cleaning place. The scraped impurities are pushed into the first dust suction port under the action of the brush bristles, thereby cleaning the larger impurities in the cleaning place.

[0036] Optionally, the floor brush housing is further provided with a second dust suction port and a third dust suction port;

[0037] The second dust suction port and the third dust suction port are relatively arranged on two sides of the floor brush housing, and the first dust suction port, the second dust suction port and the third dust suction port are connected.

[0038] By adopting the above technical solution, when cleaning the corners or gaps in the cleaning place, the first dust suction port or the third dust suction port is aligned with the cleaning place, and under the negative pressure of the vacuum cleaner, the dust is sucked into the first dust suction port through the second dust suction port and the third dust suction port, and the dust enters the vacuum cleaner through the first dust suction port, which is convenient for cleaning the corners or gaps in the cleaning place. At the same time, the second dust suction port and the third dust suction port are relatively arranged, which can quickly clean both sides of the gap and improve the cleaning efficiency.

[0039] Optionally, the cleaning assembly further includes a blocking member for blocking the second suction port and the third suction port;

[0040] The blocking member includes a blocking cylinder, a blocking bracket, a first blocking plate and a second blocking plate;

[0041] The blocking bracket is arranged on the floor brush housing through the blocking cylinder, and the movement direction of the blocking cylinder is arranged in the vertical direction;

[0042] The first blocking plate is connected to the blocking bracket, the first blocking plate can block the second dust suction port, and the first blocking plate is slidably connected to the floor brush housing;

[0043] The second blocking plate is connected to the blocking bracket, the second blocking plate can block the third suction port, and the second blocking plate is slidably connected to the floor brush housing.

[0044] By adopting the above technical solution, when cleaning a relatively regular cleaning place, the blocking cylinder moves, the blocking cylinder drives the blocking bracket to move, the blocking bracket drives the first blocking plate and the second blocking plate to move, the first blocking plate and the second blocking plate move to block the second dust suction port and the third dust suction port, and the first dust suction port is always open, which will not affect the cleaning of a relatively regular cleaning place.

[0045] In summary, this application includes at least one of the following beneficial technical effects:

[0046] 1. The present application continuously swings the connecting rod, and the movement of the connecting rod drives the movement of the floor brush housing, thereby achieving comprehensive cleaning of the cleaning place. When cleaning the corners or gaps of the cleaning place, the floor brush housing is pressed against the cleaning place, and the floor brush housing receives the pressing force, and the floor brush housing and the connecting rod rotate relative to each other, so that the first suction port is easier to approach the corners or gaps of the cleaning place, thereby facilitating the cleaning of the corners or gaps of the cleaning place;

[0047] 2. This application rotates the second connecting section, which drives the third connecting section to rotate, and the third connecting section drives the floor brush housing to move. The floor brush housing changes state, allowing the floor brush housing to extend into the gap, facilitating the cleaning of dust in the cleaning area. At the same time, the second connecting section is rotated, so that the cleaning staff only needs to stand in a fixed position to clean the gap, reducing the need for staff to move;

[0048] 3. The present application drives the rotating block to move by the rotation of the floor brush shell, and the movement of the rotating block drives the movement of the moving block. The moving block contacts the reset spring, and the spring contracts. When the external force is removed, the reset spring tends to stretch. The stretching of the reset spring drives the movement of the moving block, and the movement of the moving block drives the movement of the rotating block. The movement of the rotating block drives the movement of the floor brush shell, and the floor brush shell generates a restoring force, and the floor brush shell returns to its original state. On the one hand, it reduces the steps of regularly placing the floor brush shells for later storage, thereby improving the efficiency of use. On the other hand, it is convenient for the subsequent cleaning of other cleaning places, and there is no need to swing it manually, which further improves the efficiency of use.
