Referring to fig. 1 to 4, an embodiment of the present invention provides an air duct assembly 100 for a floor brush of a vacuum cleaner. The air channel part 100 includes a suction pipe 10 and a turbine pipe 20 connected to an outer surface of the suction pipe 10. The dust suction pipe 10 is formed with a dust suction duct 12. The turbine pipe 20 is formed with a turbine duct 22. The dust extraction duct 12 is formed with a dust extraction duct outlet 14 and the turbine duct 22 is formed with a turbine duct outlet 24.
The suction tube 10 includes a shield 16 extending inwardly from the inner wall and towards the suction duct outlet 14. The shielding piece 16 and the inner surface of the dust suction pipe 10 form a shunting space 18, and the turbine duct outlet 24 is positioned in the shunting space 18.
In the air duct component 100 of the embodiment of the invention, the shielding piece 16 in the dust suction pipe 10 guides the air flow in the dust suction air duct 12 and the turbine air duct 22, so that the air flow in the dust suction pipe 10 and the turbine air duct 20 is prevented from generating turbulence, and the cleaning effect of the dust collector floor brush is prevented from being influenced.
Meanwhile, the shielding sheet 16 also reduces the noise caused by the intersection of the air flows in the turbine air duct 22 and the dust collection air duct 12, and improves the use experience of users.
Of course, the shielding plate 16 also prevents the dust in the dust suction pipe 10 from entering the turbine air duct 22 through the turbine air duct outlet 24 to a certain extent, which causes the problems of slow air intake of the turbine air duct 22, and the like.
Specifically, the diversion space 18 communicates with the turbine duct 22 and the dust collection duct 12.
Therefore, the air flow between the turbine air duct 22 and the dust collection air duct 12 is ensured, and the pneumatic floor brush is realized.
Specifically, the air duct member 100 is made of plastic or metal.
The plastic air duct component 100 has small mass and is arranged on the dust collector floor brush 1000, so that the whole weight of the dust collector floor brush 1000 is reduced, and the movement of the dust collector floor brush 1000 is facilitated. In addition, the plastic cost is lower, and the overall cost of the dust collector floor brush 1000 is reduced; in the assembly process of the metal air duct 100, a welding method is generally used, so that the sealing performance of the air duct 100 is improved, and the cleaning effect of the dust collector floor brush 1000 is enhanced. In addition, the metal air duct 100 has high hardness, so that when the dust collector floor brush 1000 is collided or falls off, the air duct 100 is not easy to damage, and the service life of the dust collector floor brush 1000 is prolonged.
Specifically, the airflow exits the turbine duct 20 from the turbine duct outlet 24 and exits the dust extraction duct 10 from the dust extraction duct outlet 14, thereby creating a suction force towards the dust extraction duct outlet 14, such that the airflow carries the dust out of the dust extraction duct 10 from the dust extraction duct outlet 14 into a dust bag or dust box, such that cleaning of the dust on the floor will be accomplished.
In some embodiments, the turbine tube 20 and the outer side of the suction tube 10 are connected and form a turbine duct outlet 24.
Therefore, the mode that the turbine tube 20 is connected with the outer side surface of the dust collection tube 10 saves more space in the dust collector floor brush 1000, reduces the volume of the dust collector floor brush 1000, and is more convenient for a user to use and store. Meanwhile, compared with the connection mode that the turbine pipe 20 and the dust suction pipe 10 are just opposite to each other, in the connection mode, when airflow enters the dust suction pipe 10 from the turbine pipe 20, the path of the airflow impacting the inner wall of the dust suction pipe 10 is shorter, and the flow speed is higher, so that the suction force towards the direction of the dust suction air duct outlet 14 is improved, and the cleaning effect of the dust collector floor brush 1000 is further improved.
Specifically, the outer side surface in the present embodiment means that the axis x of the turbine pipe 20 and the axis y of the suction pipe 10 do not intersect with each other after the turbine pipe 20 and the suction pipe 10 are stably connected.
Further, the larger the distance between the axis x of the turbine 20 and the axis y of the suction pipe 10, the faster the airflow speed is when the airflow rushes into the suction pipe 10 from the turbine duct outlet 24, and the better the cleaning effect of the vacuum cleaner floor brush 1000 is.
In certain embodiments, the turbine tube 20 is formed with a turbine duct inlet 26, and the turbine tube 20 is tapered from the turbine duct inlet 26 to the turbine duct outlet 24.
In this way, after the air flow enters the turbine duct 22 from the turbine duct inlet 26, the path of the air flow is narrowed due to the tapered structure of the turbine duct 22, and the flow velocity of the air flow is forced to increase, so that the air flow has a higher velocity when entering the dust suction pipe 10 from the turbine duct outlet 24.
Specifically, in one embodiment, the cross-section of the turbine tube 20 in the plane of the axis x may be a cone, a tri-star, etc., without limitation.
In some embodiments, the shield 16 includes a curved portion 162 and a straight portion 164. the angle α between the axis x of the turbine tube 20 and the plane of the straight portion 164 is acute.
In this way, after the airflow in the turbo duct 22 exits from the turbo duct outlet 24, the airflow impacts the curved portion 162, and moves along the surface of the curved portion 162 and the flat portion 164 in the direction of the dust collection duct outlet 14 under the guidance of the curved portion 162, so as to drive the dust in the dust collection pipe 10 to move towards the dust collection bag or the dust collection box arranged near the dust collection duct outlet 14, thereby realizing dust cleaning. Meanwhile, the shielding piece 16 ensures the stability of the air flow movement and optimizes the dust collection effect of the dust collector floor brush 1000. Furthermore, the acute angle between the axis x of the turbine tube 20 and the plane of the straight portion 164 enables the air flow to reach the shielding plate 16 relatively quickly after exiting from the turbine tube 20, so that the air flow is guided by the straight portion 164 and the curved portion 162 to move away from the dust suction inlet 12, thereby realizing the pneumatic floor brush.
In some embodiments, included angle α is 0-30 °.
In this way, the air flow from the turbine duct 22 can impact the shielding plate 16 at a fast speed and move rapidly toward the outlet 14 of the dust suction duct, thereby cleaning the dust in the dust suction pipe 10.
Preferably, the angle α is 15 °, so that the duct component 100 has a high dust-absorbing capacity.
In some embodiments, the suction duct 12 is formed with a suction duct inlet 11. The bend 162 is streamlined opposite the suction duct inlet 11.
In this way, the airflow in the turbine duct 22 can move along the curved portion of the curved portion 162 in a direction away from the dust suction inlet 12, so as to drive the dust in the dust suction pipe 10 into the dust bag or the dust box; secondly, the airflow entering from the dust suction inlet 12 can move in a direction away from the dust suction inlet 12 along the bent portion of the bent portion 162. Meanwhile, after the air flow in the turbine air duct 22 and the air flow in the dust collection air duct 12 are guided by the shielding piece 16, the movement is more stable, and the generation of turbulent flow is avoided.
In some embodiments, the area ratio of the orthographic projection of the shielding piece 16 on the dust suction duct inlet 11 to the dust suction duct inlet 11 is greater than or equal to 40% and less than or equal to 60%.
Therefore, the air flow entering the dust collection air duct 12 in the turbine air duct 22 accounts for 40% -60% of the air flow in the dust collection air duct 12, and the dust collection efficiency of the dust collector floor brush 1000 is improved.
Preferably, the ratio of the orthographic projection of the shielding piece 16 on the dust suction duct inlet 11 to the area of the dust suction duct inlet 11 is 50%.
Thus, the air flow in the turbine air duct 22 is matched with the air flow in the dust collection air duct 12, so that the dust collection efficiency of the dust collector floor brush 1000 is improved.
A vacuum cleaner floor brush according to an embodiment of the present invention includes a bottom chassis 200 and the air channel part 100 according to any one of the above claims. The bottom chassis 200 is provided with a plurality of support ribs 202. The support ribs 202 include support surfaces 204. The support surface 204 cooperates with the outer surface of the airway member 100 to stabilize the mounting of the airway member 100.
In the dust collector floor brush in the embodiment of the invention, the shielding piece 16 in the dust collection pipe 10 guides the air flow in the dust collection air duct 12 and the turbine air duct 22, so that the air flow in the dust collection pipe 10 and the turbine pipe 20 is prevented from generating turbulence, and the cleaning effect of the dust collector floor brush is prevented from being influenced.
Specifically, the support surface 204 is arcuate.
Thus, the supporting surface 204 and the air duct member 100 can be engaged with each other, and the air duct member 100 can be stably mounted.
Further, in one example, a soft substance such as rubber may be padded between the supporting surface 204 and the wind tunnel member 100.
Therefore, when the dust collector floor brush 1000 collides or falls, the soft substance can provide buffer for the air duct component 100, reduce the risk of damaging the air duct component 100, ensure the sealing performance of the air duct component 100 and further ensure the dust collection efficiency of the dust collector floor brush 1000.
Further, the cleaner further includes an upper cover 400. In one example, the upper cover 400 is also provided with support ribs 202.
In this way, the upper cover 400 and the supporting ribs 202 of the bottom case 200 cooperate with the air duct member 100 to further ensure the stability of the air duct member 100 disposed on the floor brush 1000 of the vacuum cleaner.
In some embodiments, the vacuum cleaner floor brush includes a negative pressure part (not shown) that communicates with the turbine duct 22 and the suction duct 12 through the connection pipe 300.
Thus, the negative pressure part generates negative pressure to draw the air flow in the dust absorption air duct 12 and the turbine air duct 22 in the direction far away from the dust absorption inlet 12, thereby realizing pneumatic floor brushing.
Specifically, the negative pressure part includes a motor and a fan wheel.
Thus, the fan impeller is driven by the motor at a high speed to discharge air in the fan impeller from the negative pressure portion at a high speed, air in the dust collection air duct 12 and the turbine air duct 22 is continuously supplemented into the negative pressure portion, and dust at the dust collection inlet 12 enters the dust collection bag or the dust collection box along with air flow in the dust collection air duct 12, so that dust collection is realized.
In some embodiments, the connection tube 300 is collapsible.
Therefore, when the dust collector floor brush 1000 is in use, the connecting pipe 300 can buffer the relative motion between the negative pressure part and the main body part of the dust collector floor brush 1000, so that the connecting pipe 300 is prevented from being broken when the dust collector floor brush 1000 moves, and the service life of the dust collector floor brush 1000 is prolonged.
