Description Vacuum cleaner nozzle and vacuum cleaner

The present invention provides a vacuum cleaner nozzle with a roller brush and a vacuum cleaner including the vacuum cleaner nozzle.

Background technique

Nozzles with roller brushes have long been widely used in the vacuum cleaner industry. The roller brush comprises a roller body (generally cylindrical) and a brush wire disposed on the surface of the roller body. When rotating at a high speed, the brush wire can pat the surface of the carpet or the fabric furniture, and the surface of the carpet or the dust hidden deep in the carpet Excited, easy to be sucked away. At the same time, the brush can also pick up the hair of the carpet or fabric furniture as well as the flocculent dust. However, the traditional roller brush nozzles are more suitable for granular dust, which can be excited from the depth of the carpet and sucked away, while the hair and the flocculation dust are more likely to be wrapped around the rotating roller brush, and the user is still vacuumed. Try to clean the hair wrapped around the roller brush.

US20090229075A1 Electrolux discloses a roller brush cleaning mechanism for driving a scraping blade parallel to the roller brush by means of a mechanical transmission mechanism. When the roller brush needs to be cleaned, the dusting blade is moved closer to the brush wire, and then the roller brush is driven. Rotate, rub the wiper with the brush and scrape the hair attached to the tip of the brush down into the air duct to be sucked away. This kind of mechanism is complicated, the manufacturing cost is relatively high, and the hair is first accumulated and then cleaned, and the hair may be wrapped around the roller during the accumulation process, so that the scraping blade cannot scrape it.

US20120260457A1 Miele discloses a vacuum cleaner nozzle with a turbine that axially enters the air and a smooth air duct for the dust, but no special design prevents the hair from getting caught on the roller brush.

We have found that in the above two designs, the airflow of the brushed edges on both sides of the brush is immediately blocked by the nozzle housing behind the roller brush, and a vortex is formed at the edge of the roller brush, and a part of the airflow flows to the nozzle. The air outlet is fan-shaped and converges toward the air outlet of the nozzle, and the convergence route crosses the direction in which the filament extends. The hair raised by the brush filaments on both sides of the roller brush is both agitated by these filaments and blocked by the casing, and is also attracted by the airflow, and is subjected to other filaments in the process of leading to the nozzle outlet port. Blocking, in these processes, longer hair tends to tail, not easily sucked away by the airflow, and may eventually entangle with the roller. Summary of the invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a vacuum cleaner nozzle and a vacuum cleaner according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in Fig. 1, the dust suction device 100 includes a vacuum cleaner nozzle 10, a duct connecting portion 101, and a dust suction portion 102. The vacuum cleaner nozzle 10 is matched with the air duct connecting portion 101 for cleaning hair and dust on a surface to be cleaned such as a carpet, a sofa, or the like. The dust suction unit 102 provides suction to the vacuum cleaner nozzle 10, and sucks hair, dust, and the like cleaned by the vacuum cleaner nozzle 10, and accommodates the hair, dust, and the like as a dust collector dust collecting mechanism.

As shown in Figs. 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10, the vacuum cleaner nozzle 10 includes: a body 11, a roller brush 12, and a driving member 13.

The body 11 includes an upper cover portion 20, a lower cover portion 36, a partition 55, a partition plate 71, and a roller end cover 21. The upper cover portion 20 is provided with a through hole 51 and a semicircular hole 63. The lower cover portion 36 is composed of a front end portion and a rear end portion. The rear end portion is provided with an interface member 50 that is coupled to the air passage connection portion 102 of the vacuum cleaner 100, and a card is provided on the front end portion of the lower cover portion 36. The buckle 58 engages with the through hole 51 of the upper cover portion 20 so that the upper cover portion 20 and the lower cover portion 36 can be tightly coupled together. The lower cover portion 36 is also provided with semicircular holes 57 and 59 for accommodating the roller brush 12.

The partition 55 is disposed between the lower cover portion 36 and the upper cover portion 20, and the partition 55 and the lower cover portion 36 are combined to form a dust suction air passage 60, and a damper 56 located at the foremost end of the dust suction air passage 60 (see FIG. 7). Here, the damper 56 is used to introduce wind into the dust suction duct 60, and the dust suction duct 60 is used to introduce the wind into the interface member 50 from the suction opening 56 through the roller brush 23 into the damper 56. The upper portion of the damper 56 is the lower end portion of the partition plate 71, and the lower portion is the inner wall of the lower cover portion 36, and the both sides are the inner walls of the body 11, respectively. The damper 56 is smoothly connected to the dust suction opening 61, and the inner wall of the lower cover portion 36 itself is also in a smooth shape, so that wind, dust, hair, and the like entering from the dust suction opening 61 can be smoothly along the inner wall of the lower cover portion 36. The ground enters the dust suction duct 60.

In the present embodiment, the size of the wind speed entering the damper 56 can be adjusted by adjusting the distance H of the lower end portion of the partition plate 71 from the partition 55. For example, to reduce the wind speed, H can be set to zero, that is, the height of the damper 56 can be equal to the height of the dust suction duct 60 (ie, the lower surface of the partition 55 can be flush with the highest point of the damper 56) ( See Figure 7).

After the upper cover portion 20 and the lower cover portion 36 are coupled, a hollow front end portion is formed between the front end portion of the upper cover portion 20 and the front end portion of the lower cover portion 36, and a vacuum is provided on the hollow front end portion. Referring to the opening 61 of the book, the airflow passes through the damper 56 from the dust suction opening 61, passes through the dust suction air passage 60 and the interface member 50 (the nozzle air outlet), and flows into the dust suction portion 102 of the dust suction tool. The lower cover portion 36 is also provided with a semi-circular hole 62 which cooperates with the semi-circular hole 63 of the upper cover portion 20 to form a full circle for arranging the drive member 13 (see Fig. 2).

The roller brush end cover 21 is for fixing the roller brush 12, and ensures that the roller brush 12 can smoothly and continuously rotate at a high speed under the action of the driving member 13.

As shown in Fig. 9, in the present embodiment, the length B of the opening of the damper 56 is larger than the length A of the distribution range of the plurality of filaments 23 in the axial direction of the roller body 22.

As shown in Fig. 9, in the present embodiment, the damper 56 is located between the roller brush 12 and the interface member 50, adjacent to the roller brush 12 and away from the inlet of the interface member 50. The dust suction duct 60 connects the damper 56 and the interface member 50.

As shown in Figs. 4, 10 (A), the roller brush 12 is disposed in the hollow front end portion, and includes a roller body 22, a plurality of filaments 23, and a plurality of strips 24. The side of the roller body 22 has a driven groove 52. The driven groove 52 cooperates with the driving head 53 of the secondary large gear 25 for receiving the torque of the output of the secondary large gear 25 to drive the roller 22 to rotate. The roller 22 also has a rotating shaft, and the longitudinal direction of the damper 56 is parallel to the rotating shaft. A plurality of filaments 23 are mounted in a spiral arrangement on a plurality of holes in the surface of the roller body 22, and a plurality of sets of spiral filaments are formed on the surface of the roller body 22. The different holes on the surface of the roller body 22 are isolated from each other. A spiral groove 64 is formed between the two sets of spiral filaments 23, and the strip 24 is fixed in the spiral groove 64, and the height of the strip 24 is slightly lower than the height of the filament 23. In this embodiment, a total of twenty-four filaments are mounted on the surface of the roller body 22. The twenty-four filaments are divided into two groups and mounted on the surface of the roller body 22. The two strips 24 are fixed in two spiral grooves. 64.

Of course, the roller brush 12 is not limited to the above structure. As shown in FIG. 10(B), a convex continuous spiral rib 12a may be provided on the surface of the roller body 22, and the brush wire 23 may be attached to the spiral rib 12a adjacent to each other. The structure of the roller brush 12 is formed in a plurality of holes, or the brush wire 23 may be first mounted on the intermediate carrier, and then the intermediate carrier is fixed in the spiral groove in the spiral rib 12a to form a structure of the roller brush 12.

It is also possible to mount the brush wire 23 on the intermediate carrier first, and then fix the intermediate carrier to the roller body 22, for example, as shown in Fig. 10(C), in the spiral groove of the surface of the roller body.

In the above-mentioned roller brush 12, each set of the filaments 23 is fixed on the roller body 22 in a spiral arrangement. In this embodiment, the roller brush 12 may also have the structure shown in FIG. 10(D): A set of filaments 23 are fixed to the roller body 22 in a staggered manner, and the adjacent two sets of filaments 23 are also misaligned so that the filaments 23 can continuously pat the surface to be cleaned during the rotation. The specification is as shown by the dotted line in FIG. 9(A) and the area enclosed by the inner wall of the lower cover portion 36. In the present embodiment, the dust suction air passage 60 has the front guide portion 60a and the communicating with the damper 56. The rear guide portion 60b that the interface member 50 communicates with. And the longitudinal section of the leading portion 60a is not smaller than the longitudinal section of the rear guide portion 60b, and the dust suction air passage 60 is bilaterally symmetrical along the extension line of the central axis of the interface member 50 (see Fig. 9A).

Figure 9 (A) is a schematic view showing the flow direction of the brush wire 23 in the middle of the roller body 22 when it is turned to the damper 56, and Figure 9 (B) is the wire on both sides (i.e., the left and right portions) of the roller body 22. 23 indicates the direction of the airflow when the damper 56 is turned. As shown in Figs. 9(A) and 9(B), the leading portion 60a allows the airflow formed by the wind flowing through the roller brush 23 to enter the damper 56 in the same direction, and the SP and the leading portion 60a pass the airflow in parallel through the filament 23. The filaments 23 on the roller 22 are distributed over the three positions of the left, middle and right portions of the roller body 22. The function of the leading portion 60a is to allow the airflow to pass through the three position regions of the left, middle and right portions. The instantaneous directions of the tips of the filaments 23 are the same, that is, regardless of the rotation of the filaments 23 on the roller 22 to any direction, the directions of the airflows at the left, middle and right positions in the figure are parallel to each other, and the airflows are not mutually exclusive. The interference is such that the hair can smoothly escape from the filament 23 and follow the airflow into the damper 56, and then sucked and received by the dust suction portion 102 along the dust suction air passage 60. The center line of the rotating shaft of the roller and the central portion of the leading portion 60a in the direction of the suction air flow may be located in the same plane.

In the present embodiment, the length of the leading portion 60a is equal to the length of the damper 56, and the leading portion 60a extends a certain distance E in the direction toward the interface member 50. The certain distance E is not less than the height of the brush wire 23 (i.e., the size of the surface of the roller 22 exposed by the brush wire 23), so as to ensure the airflow passing through the edge of the most edge brush 23 on both sides of the roller 22 and the airflow passing through the center of the roller body 22. The direction is the same.

One end of the rear guide portion 60b is matched with the front guide portion 60a, and the other end is matched with the interface member 50. The front guide portion 60a and the interface member 50 are connected, and the airflow passing through all the wires 23 in the same direction is concentrated to allow the slave wire to be brushed. The detached hair on the 23 follows the airflow into the dust suction portion 102. In the present embodiment, as shown by the dotted line in FIG. 9(A) and the area surrounded by the inner wall of the lower cover portion 36, the leading portion 60a has a rectangular cross section in the direction from the damper 56 to the interface member 50. The rear guide portion 60b has a flared cross section in the direction from the interface member 50 to the damper 56.

In this embodiment, as shown in FIGS. 5 and 11, the interface member 50 may include a fixed interface 50a, and a conversion interface 50b. One end of the fixed interface 50a is fixedly connected to the rear guide 60b, and the other end may be connected to one end of the conversion interface 50b. Matching, the other end of the conversion interface 50b is matched with the air duct connection portion 101, and is used to connect the fixed interface 50a with special The duct connection portion 101 of the inner diameter of the book is explained. The inner diameter of the interface member 50a can also be made to match the inner diameter of the air duct connecting portion 101 so that the two can be directly fitted without passing through the switching interface 50b.

The size and relationship of the damper 56, the roller brush 12 and the dust suction duct 60 are set such that the airflow entering the damper 56 through the rear of the brush wire 23 located at the most edge of the two sides of the roller body 22 passes through the roller body 22. The airflow direction of the center of the brush wire 23 entering the damper is uniform, and the hair raised by any one of the filaments 23 can fly into the damper 56 along the tangential direction on the rotation track of the filament 23 under the action of centrifugal force, and further As the suction airflow flows toward the dust suction portion 102 (in this case, the air flow direction is also perpendicular to the rotation axis), it does not collide with other filaments 23 to entangle. This is similar to a football shot to an empty goal: It would be easy if you shot from the front of the goal and close to the goal. If it is a corner kick, and the opponent's players are densely arranged to block, although there is no goalkeeper, it is still difficult to enter.

The rotational speed of the roller brush 12 is very high, and is generally designed to be between 500 and 5000 rpm, preferably about 2,000 to 2,500 rpm. Both the roller 22 and the brush 23 are smooth. During the experiment on the floor, it was found that the hair could not find a foot on the roller 22 and the brush 23, and after being brushed by the high-speed rotating wire, Under the combined action of the centrifugal force and the suction force, it flies into the damper 56 in the tangential direction of the rotational path of the filament 23, and is sucked away without being wound around the roller brush 12.

The tip end of the brush wire 23 on the roller brush 12 can be designed to protrude outward from the plane of the suction opening 61 by about 1 mm, or it can be designed to be flush with the plane of the suction opening or slightly lower than the plane of the suction opening 61. Taking the carpet as an example, during the vacuuming process, when the vacuum cleaner nozzle 10 is pressed against the surface of the carpet, a negative pressure is generated in the vacuum cleaner nozzle 10, and the surface layer of the carpet is sucked up, and the dust suction opening 61 is blocked by the surface layer of the carpet. The tip end of the filament 23 extends into the batt of the carpet, slaps the carpet and the sofa during high-speed rotation, irritates the dust deep in the carpet, and picks up the surface of the carpet as well as the internal hair. Further, when the suction opening 61 is blocked by the surface layer of the carpet, the airflow passing through the axial flow turbine is increased, and the driving force is increased, and at this time, the rotational speed of the roller brush 12 is correspondingly increased.

In order to more effectively pry the hair from the high-speed rotating roller brush 12, each of the brushes 23 is smooth and straight, and its extending direction is as perpendicular as possible to the rotating shaft of the roller body 22, and avoiding overtightening between any two of the wires 23 Arrange, to avoid the hair being clamped by the brush 23, the roller 22 should also be smooth, and the hair should not be allowed to find a foothold.

The individual filaments 23 may have a diameter between 0.1 and 0.2 mm, and a plurality of such filaments 23 are assembled to form a cluster to increase the strength. The diameter of the individual filaments 23 can also be between 0.5 and 1.0 mm, so that the relatively thin filaments 23 can have sufficient strength to clean the carpet. The instruction drive member 13 is used to drive the roller brush 12 for continuous high speed rotation. As shown in FIG. 4, in the present embodiment, the driving member 13 is an axial flow turbine, which includes: a blade bracket 29, an air guide bracket 35, a fan blade 34, a transmission shaft 33, a primary pinion 31, and a combined gear. 30. The combination gear 30 includes a primary large gear 69, a secondary pinion 70, a secondary large gear 25, bearings 26 and 37, shafts 32 and 33, a washer 27, and a screw 28.

In the present embodiment, as shown in FIGS. 4, 5, 6, and 8, the body 11 further has a driving air inlet duct 65 that axially enters the wind introduction interface 50 of the axial flow turbine, and the driving air inlet duct 65 is installed at The partition 55 is spaced apart from the dust suction passage 60, one end of which is fixedly connected to the vane bracket 29, and the other end of which is connected to the interface member 50 for guiding the airflow flowing through the vane 34 to flow into the interface member in an appropriate direction. In 50, the airflow from the outside of the blade 34 into the driving air duct 65 may be parallel to the axis of rotation of the blade 34 or may be at an angle of less than 45°.

In the present embodiment, the interface member 50, the dust suction air passage 60, and the drive air passage 65 constitute a duct portion that guides the wind outside the body 11 into the air passage connecting portion 101. As shown in FIG. 7, in the air duct portion 50, the driving air passage 65 and the dust suction air passage 60 are separated from each other and divided into upper and lower layers, wherein the driving air passage 65 is located at the upper layer of the dust suction air passage 60. .

The blade bracket 29 is provided with an air guide bracket cover 66 and a bearing chamber 67. The air guide bracket cover 66 is used to mount the air guide bracket 35 and the air vane 34. The bearing chamber 67 is used to mount the bearing 26.

The air guide bracket 35 is provided with air guiding vanes 54, so that the air flow passing through the air guiding vanes 54 is deflected to effectively push the vanes 34 to obtain the maximum torque and rotational speed of the vane 34. The air guide bracket 35 is also provided with a bearing chamber 68 for mounting the bearing 37.

The primary pinion 31, the combined gear 30, and the secondary large gear 25 form a transmission system that transmits the torque generated by the blades 34 to the roller 22 to allow the roller 22 to rotate. The combination gear 30 has a primary gear 69 and a secondary pinion 70, the primary gear 69 is used to receive the torque transmitted by the primary pinion 31, and the secondary pinion 70 is used to transmit the torque to the secondary large gear 25. The secondary large gear 25 is provided with a drive head 53 for transmitting a torque to the roller 22 to drive the roller 22 to rotate.

Bearings 37 and 26 are used to support the secondary bull gear 25 and the drive shafts 32 and 33, respectively.

The intake damper is brought into the dust suction portion by the suction airflow, and no longer needs to converge toward the center along the axial direction of the roller brush. Therefore, after the hair of the surface to be cleaned is lifted by a set of filaments, it will not be contacted with other filaments during the process of leading to the dust collecting device, and the hair and the filament and the winding body can be significantly reduced. opportunity.
