Description

Vacuum cleaner nozzle and vacuum cleaner Technical field

The present invention particularly relates to a vacuum cleaner nozzle and a vacuum cleaner including the vacuum cleaner nozzle.

Background technique

Vacuum cleaners have been widely used in ordinary households, which can easily absorb dust, but the cleaning effect on hair has not been good, because the hair is easy to adhere to the surface of the carpet or fabric sofa, and it is difficult for ordinary nozzles to suck it. go. A nozzle with a rotating roller brush already appears, and the rotating roller brush contains a roller body and a brush wire. During high-speed rotation, the brush can carry away the hair adhering to the carpet, but most of the hair that is brushed away from the ribbon does not actually enter the dust collecting mechanism of the vacuum cleaner, but is wound on the roller, and because It rotates at a high speed and is tightly wound with the roller. It is difficult to remove, and the user must try to clean the hair wrapped around the roller after vacuuming. Therefore, the problem of hair cleaning has not been solved.

Patent document WO2015035545A discloses a suction nozzle, which is provided with a damper behind the rotary roller brush. The opening width of the damper is not less than the width of the distribution range of the brush wire on the roller body, and the air guiding channel is arranged behind the damper, so that each wire is pointed In the case of the damper, the direction of the airflow flowing through the filament into the damper is the same as the direction in which the filament is extended, so that the suction airflow is more likely to peel the hair from the filament, preventing the hair from following the filament across the damper and winding on the roller. It has been found that the hair removal effect of the nozzle disclosed in the patent document WO2015035545A is superior to that of the conventional nozzle with a rotating roller brush, which significantly reduces the phenomenon of hair entanglement on the roller. However, if the hair is held tightly across the damper between the plurality of filaments, the hair will still wrap with the roller; or the initial position where the hair is in contact with the filament is not at the tip of the filament, but in the brush At the root of the wire, this also causes the hair to be smoothly sucked away as the brush passes through the damper, but is wound around the damper around the damper, and becomes more and more tight as the roller rotates at a high speed, and is finally difficult to remove.

The suction force is transmitted to the edge of the bottom air deflector 29 so that dust and hair can enter the dust collecting suction port from the dust suction opening 28 of the casing 11, and then enter the air duct inlet 30 to be sucked away. The bottom surface of the inner ring may be slightly higher than the bottom surface of the outer ring, and the lower edge of the bottom air deflector 29 may be slightly higher than the bottom surface of the inner ring. Such a progressive structure facilitates the entry of hair and dust into the air duct inlet.

As shown in FIGS. 3 and 8, the axial flow turbine 32 and the rotating shaft 33 are coupled to the bearing 35 through the bearing mounting shaft 54, and when the suction airflow hits the axial flow turbine 32, the bearing mounting shaft 54 can freely rotate in the bearing. The drive gear 41 driving the bearing mounting shaft 54 is rotated. The bearing is located inside the bearing chamber 55, and in order to clearly express other parts, FIG. 8 only shows the bearing chamber 55 and does not show the bearing and the drive gear 41.

The reverse mechanism 15 includes an internal gear 45 provided on the outer base portion 14, an external gear 44 provided on the inner base portion 13, and a reverse gear 46. The rotating shaft 40b of the reverse gear 46 is fixed (see Figs. 1 and 3), and the reverse gear is engaged by the bearing, and the reverse gear can be freely rotated about the fixed rotating shaft 40b.

The internal gear 45 is provided at the upper end of the outer duct portion 48.

The reduction gear is coupled to the fixed rotating shaft 40a by a bearing and is rotatable about the rotating shaft 40a, and includes an integrally formed upper gear 42 and a lower gear 43. The upper gear 42 meshes with the drive gear 41, and is rotated by the drive gear 41 to drive the lower gear 43 integrated therewith. The lower gear 43 meshes with the external gear 44 of the inner base portion 13, and drives the external gear 44 to rotate. The outer diameter of the upper gear 42 is much larger than the outer diameter of the drive gear 41, so the rotational speed of the upper gear 42 is lower than the rotational speed of the drive gear 41. The diameter of the lower gear 43 is smaller than the diameter of the outer gear 44. The reduction ratio from the turbine 32 to the external gear 44 is approximately 1:15, i.e., from about 30,000 or so per minute of the axial turbine 32 to about 2,000 revolutions per minute of the external gear 44.

The reverse gear 46 is disposed between the external gear 44 and the internal gear 45 while meshing with the external gear 44 and the internal gear 45 such that the external gear 44 and the internal gear 45 are reversed each other, thereby causing the inner base portion 13 and the outer base portion 14 reversing each other around the same central axis. The rotational speed of the outer gear 44 is slightly higher than the rotational speed of the inner gear 45.

As shown in FIGS. 1 and 3, 40a is a reduction gear positioning shaft, and 40b is a reverse gear positioning shaft that closely fits the housing 11 and the tip is exposed on the surface of the upper cover 20. During the rotation, both the reduction gear and the reverse gear 46 rotate about a respective positioning axis at a fixed position.

As shown in FIGS. 3, 6, and 8, in the present embodiment, the drive member includes the axial flow turbine 32. The axial flow turbine 32 is disposed within the drive air duct 26. The air guide cover 31, the axial flow turbine 32, the transmission shaft 33, the bearing chamber 34, and the bearing 35 are provided in this order from the top to the bottom of the drive air duct 26. The drive duct 26 communicates with the connecting duct portion 25.

The intake port of the drive air duct 26 is provided at the top of the upper cover 20. The air guiding cover 31 is disposed outside the air inlet of the driving air duct 26, and a mesh cover for blocking foreign matter may be attached to the outer side of the air guiding cover 31. The axial flow turbine 32 and the drive shaft 33 are tightly coupled, and the lower portion of the drive shaft 33 is provided with a bearing mounting shaft 54. The bearing 35 is sleeved on the periphery of the bearing mounting shaft 54. The drive gear 41 is in close cooperation with the drive shaft 33. The driving airflow flows in from the intake port, and the axial fan 32 is rotated by the air guiding cover 31 in the driving air passage 26 to drive the driving gear 41. The airflow passes through the axial flow turbine 32 and then flows along the connecting duct portion 25 to the air outlet duct portion 24.

The working process of the vacuum cleaner nozzle of this embodiment is as follows:

The vacuum cleaner nozzle 10 is connected to the suction port of the vacuum cleaner and the vacuum cleaner is activated. The suction port portion may be located at the end of the extension pipe of the ordinary vacuum cleaner, may be located below the main body of the vertical vacuum cleaner, or may be located at the front of the dust cup of the car vacuum cleaner. The suction port portion may be in direct communication with the vacuum cleaner nozzle 10 or may be indirectly connected through the outlet pipe portion 24. The airflow flows simultaneously from the intake port of the axial flow turbine 32 and the intake port 30 of the suction air passage, and the axial flow turbine 32 is rotated by the air guide cover 31 in the drive air passage 26, and flows through the axial flow turbine 32. Then, it flows along the connecting duct portion 25 to the outlet duct portion 24.

The axial flow turbine 32 drives the drive gear 41 to rotate, and further, the drive gear 41 drives the reduction gear. The reduction gear drives the external gear 44, which in turn drives the reverse gear 46 to rotate. The reverse gear 46 in turn drives the internal gear 45 to rotate counter-rotating relative to the external gear 44.

The inner base portion 13 and the outer base portion 14 are mutually reversed about the same central axis, and the outer brush bar 38 lifts dust and hair, and the dust and hair enter the horn-shaped dust collecting suction port by the suction airflow. If hair is hung on the outer brush strip 38, the inner brush strip, which is counter-rotating relative to the outer brush strip, pulls the hair toward the end of the outer brush strip 38 each time the hair is encountered. The relative speed of the inner brush strip and the outer brush strip is about 4,000 rpm, and the inner brush strip is more than one set, and the number of pulls of the hair hanging on the outer brush strip is 8000 times or more per minute, so the hair that is being held is It is always pulled to the end of the outer brush strip and lifted up by the inner brush strip, eventually falling into the air stream and being sucked away. If the hair is pulled Hanging on the inner brush strip will also be peeled off by the outer brush strip due to the same pulling action. With 8,000 or more pulls per minute, the hair can be quickly exchanged between different brush strips, and finally the stripped strips are sucked into the air stream and sucked away.

The role and effect of the embodiment

According to the vacuum cleaner nozzle and the vacuum cleaner of the embodiment, since the vacuum cleaner nozzle is provided with the inner base portion, the outer base portion, and the reverse mechanism, the inner base portion and the outer base portion can be surrounded by the reverse mechanism. The same central axis reverses each other, so that the outer cleaning part and the inner cleaning part can reverse each other, the hair and dust on the hard floor leave the hard floor due to suction, and the hair and dust on the carpet are combined by the suction and the agitating of the outer brush strip. Leaving the carpet, in both cases, dust and part of the hair will be sucked away into the suction duct, and some of the hair may be gripped by the outer brush strip, following the outer brush strip, and it is impossible to suck it by suction alone. Peeling from the outer brush strip, at which point the inner brush strip, which is counter-rotating relative to the outer brush strip, interacts with the clamped hair, pulling them to the end of the outer brush strip and eventually allowing them to fall into the air stream to be sucked go. Therefore, when the user uses the vacuum cleaner nozzle of the embodiment and the cleaner to clean the dust and hair of the surface to be cleaned, the user can actually enter the vacuum cleaner instead of being wound inside the nozzle.

In addition, since the end of the inner brush strip is higher than the bottom surface of the frame body, the end of the outer brush strip passes through the dust suction port, and the inner brush strip is inclined toward the entrance of the dust suction duct, and the inner brush strip is away from the entrance of the dust suction duct. More closely, therefore, after the inner brush strip peels off the hair wrapped around the outer brush strip, the peeled hair is more likely to enter the air flow instead of being wound inside the nozzle.

In addition, the flared opening below the suction duct can also transmit the suction force to the vicinity of the inner brush strip, so that the hair stimulated by the brush strip is more attracted and more easily sucked away.
