[0037] See also Figure 1-3 The present invention provides a technical solution: a floor brush with adjustable suction direction, comprising:

[0038] The floor brush body 1 has a roller brush chamber 11 with a bottom opening therein, and a dust collection port 12 extending from the rear side of the roller brush chamber 11. The floor brush body 1 includes a floor brush base (shown in the figure) and a floor brush top cover (not shown in the figure). The floor brush base and the floor brush top cover are assembled and positioned up and down to form the roller brush chamber 11 with only a bottom opening and the dust collection port 12 with only a rear end opening therein.

[0039] A roller brush 2 is driven and assembled in the roller brush chamber 11;

[0040] a rotating shaft 3, which is rotatably and sealedly assembled at the outlet of the dust collecting port 12 along the axis of the dust collecting port 12;

[0041] A connecting shaft 4, one end of which is connected to the rotating shaft 3, and the other end of which is connected to the cleaning device host;

[0042] The ends of the ventilation pipe 5 are respectively passed through and positioned in the rotating shaft 3 and the connecting shaft 4, and a dust collecting elbow 6 is extended from the front end thereof, and the rear end thereof is connected to the air inlet of the main body of the cleaning device. The dust collecting elbow 6 extends into the dust collecting port 12, and its front end is bent downward and arranged at an angle.

[0043] The floor brush of the present invention is intended to solve the problem that the suction direction of the floor brush of the existing vacuum cleaner is fixed and cannot be flexibly adjusted according to actual cleaning needs. The ventilation pipe and the connecting shaft of the floor brush are rotatably connected to the floor brush through the rotating shaft, so that the dust collecting elbow in the dust collecting port can rotate freely within a certain range. When the user rotates the connecting shaft and the rotating shaft, the ventilation pipe moves synchronously, so that the dust collecting elbow and the cleaning surface form an optimal dust suction angle, thereby increasing the local airflow suction in the roller brush cavity, so as to carry out targeted cleaning of the cleaning surface and the roller brush part, thereby achieving the function of improving the dust collection efficiency, overcoming the problems of the open design of the roller brush cavity and the dust collecting port in the common floor brush, and the fixed suction direction, which results in insufficient suction, poor cleaning effect on the cleaning surface, stubborn and agglomerated dust and hair, and inability to achieve targeted dust collection and cleaning in multiple directions and different positions.

[0044] In one embodiment, the dust collection port 12 is trumpet-shaped, with its rear end abutting against the rear end outer surface of the dust collection elbow 6 and its front side surface matching the bottom of the front end outer surface of the dust collection elbow 6. This refined design ensures that when the rotating shaft 3 rotates and the dust collection elbow 6 is adjusted to different angles, the dust collection port 12 can support and limit the dust collection elbow 6, preventing the end from vibrating due to airflow and colliding with the floor brush, thereby achieving stable dust collection and low-noise operation.

[0045] In order to improve the stability and sealing of the rotational assembly of the rotating shaft 3 and the floor brush body 1, a first end 31 is provided at the front end of the rotating shaft 3, and a plurality of ribs 33 are axially distributed on the outer surface of the first end 31. The ribs 33 can be rotatably embedded in the groove of the annular guide frame 14 at the rear end of the dust collecting port 12 on the floor brush body 1.

[0046] In addition, a support base 13 is provided at the rear end of the floor brush body 1, and the rotating shaft 3 abuts against the support base 13. The support base 13 provides multi-faceted support for the stepped rotating shaft 3, which is designed in sections. This ensures the structural stability of the rotating shaft 3 when the dust collection elbow 6 and ventilation pipe 5 are impacted by airflow.

[0047] In one embodiment, the rear end of the rotating shaft 3 is provided with a second end 32, from which extends an arc-shaped rotating seat 34. Sockets 35 are provided on either side of the rotating seat 34. A connecting ear 41 is provided at the front end of the connecting shaft 4. An insert 42 extends from the side of the connecting ear 41 and rotatably inserts into the insert 35. While the rotating shaft 3 is connected to the floor brush body 1 via the x-axis rotation, its assembly with the connecting shaft 4 utilizes a y-axis rotation. This increases the flexibility of adjusting the position of the floor brush and vacuum cleaner via the connection structure, allowing for more diverse usage and expanding its applicability to a wider range of people.

[0048] In addition, the outer end surface of the insert block 42 is provided with several slots. The insert block 42 is also equipped with a reinforcement cover 36. The hooks 37 on the inner end surface of the reinforcement cover 36 engage within the slots, and the edge of the reinforcement cover abuts the outer side of the rotating seat. Based on the rotatable connection between the socket 35 and the insert block 42, the reinforcement cover 36 cooperates with the connecting lug 41 to form a sandwich-type positioning structure with the rotating seat 34, ensuring the stability of the rotational connection. The design of the hooks 37 and the slots not only ensures the connection strength between the reinforcement cover 36 and the connecting lug 41, but also squeezes the edge of the insert block 42 laterally outward, achieving structural pre-tightening of the socket 35 and the insert block 42.

[0049] An external thread 51 is provided on the surface of the ventilation pipe 5, and its ends are screwed and positioned in the first internal thread 38 of the rotating shaft 3 and the second internal thread 43 of the connecting shaft 4 through the external thread 51, which facilitates assembly and ensures seamless connection between the ventilation pipe 5 and adjacent structures, thereby ensuring dust collection efficiency.

[0050] In addition, a sealing ring is provided between the end of the ventilation pipe 5 and the first internal thread 38 and the second internal thread 43 to further ensure a sealed assembly.

[0051] The assembly process and working principle of a floor brush with adjustable suction direction in this embodiment include the following: During assembly, the ends of the ventilation tube 5 are sealed and screwed onto the rotating shaft 3 and the connecting shaft 4, respectively; the rib 33 is inserted into the groove of the annular guide frame 14, and the dust collection elbow 6 is arranged in the dust collection port 12; after the roller brush 2 is assembled on the floor brush body 1, the floor brush base and the floor brush top cover are positioned; the connecting ear 41 is internally pressed to move the insert 42 into the socket 35 of the rotating seat 34, and the connecting ear 41 is loosened to ensure stable docking between the socket 35 and the insert 42; finally, the hook 37 is aligned with the slot of the insert 42, and the reinforcement cover 36 is assembled on the insert 42. After assembly is completed, the rotational flexibility of the rotating shaft 3 and the connecting shaft 4 are tested to see if there is any jamming.

[0052] The working principle of the above-mentioned floor brush structure is specifically as follows: when the user rotates the connecting shaft and the rotating shaft, the ventilation pipe moves synchronously, so that the dust collecting elbow and the cleaning surface form the best dust suction angle, thereby increasing the local airflow suction in the roller brush cavity, so as to carry out targeted cleaning of the cleaning surface and the roller brush part, thereby achieving the function of improving the dust suction efficiency, and overcoming the problems of the open roller brush cavity and dust collection port and fixed suction direction in the common floor brush, which result in insufficient suction, poor cleaning effect on the cleaning surface, stubborn and agglomerated dust and hair, and inability to achieve targeted dust collection and cleaning in multiple directions and different positions.

[0053] In summary, due to the adoption of the above technical solution, the floor brush with adjustable suction direction of this embodiment has the following beneficial effects compared with the prior art:

[0054] The floor brush of the present invention is intended to solve the problem that the suction direction of the floor brush of the existing vacuum cleaner is fixed and cannot be flexibly adjusted according to actual cleaning needs. The ventilation pipe and the connecting shaft of the floor brush are rotatably connected to the floor brush through the rotating shaft, so that the dust collecting elbow in the dust collecting port can rotate freely within a certain range. When the user rotates the connecting shaft and the rotating shaft, the ventilation pipe moves synchronously, so that the dust collecting elbow and the cleaning surface form an optimal dust suction angle, thereby increasing the local airflow suction in the roller brush cavity, so as to carry out targeted cleaning of the cleaning surface and the roller brush part, thereby achieving the function of improving the dust collection efficiency, overcoming the problems of the open design of the roller brush cavity and the dust collecting port in the common floor brush, and the fixed suction direction, which results in insufficient suction, poor cleaning effect on the cleaning surface, stubborn and agglomerated dust and hair, and inability to achieve targeted dust collection and cleaning in multiple directions and different positions.

[0055] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
