Centrifugal force grit is separated from air-flow, grit by cyclone separator 2 side wall on dust mouth get rid of to dirt cup, gas
Stream continues through the extra large filtering of pa box 4 and enters in aspiration motor 1, extra large pa box 4 is not got rid of for filtering under aspiration motor effect
Grit into dirt cup.
The utility model embodiment sweeping robot, the cyclone separator used change due to air flow outlet arrangement
Become, is changed to side opening guidance air-flow outflow, cyclone separator is most downgraded, so that utility model embodiment
The structure of sweeping robot is more compact, short and small, specific as follows.
Fig. 4 to Fig. 7 shows the specific structure of the cyclone separator of the utility model embodiment sweeping robot use, should
Cyclone separator has annular compartment 10, is used to form swirling eddy, annular compartment 10 constitutes phase by inner wall 11 and outer wall 12
To closed space, inner wall 11 has air-flow through-hole 13, and air-flow through-hole 13 is circular hole, but not limited to this, it is passed through by isolated air-flow
Air-flow through-hole 13 flows to aspiration motor, and outer wall has dust mouth 14, for grit to be thrown away, annular compartment 10 and inlet channel 20
Be connected, dust-contained airflow by inlet channel 20 enter annular compartment 10 in, form swirling eddy in annular compartment 10, from
Under mental power function, dust particle, which is separated, to be thrown to outer wall 12 and throws away by dust mouth 14 into the dirt cup for collecting dust, gas
Stream passes through 13 aspiration motor of air-flow through-hole of inner wall 11.
Referring to figure 6 and figure 7, it is between inner wall 11 and outer wall 12 in the bottom of annular compartment 10 and the upward spiral shell of spiral is set
Skew wall 15 is revolved, spiral skew wall 15 connects with inner wall 11, outer wall 12, and the area of space formed below spiral skew wall 15 can just
As the outlet passageway 16 of air-flow outflow, the inner cavity that inner wall 11 has constitutes outlet chamber, side and spiral in inner wall 11
The corresponding position of skew wall 15 opening, the outlet passageway 16 of side is connected with outlet chamber.Swirling eddy carries out dust and gas separation
When, entered in outlet chamber room by isolated air-flow by the air-flow through-hole 13 of inner wall 11, flowed outwardly using outlet passageway 16,
The structure type that abandoning tradition is directed air flow out in outlet chamber bottom opening is changed to side opening, does not need between being additionally arranged
Gap region H, in this way, thus efficiently reducing the height of entire separator, overall structure is more compact, reasonable.
Moreover, the setting of spiral skew wall 15, additionally it is possible to guide flow spiral to rise, improve dust and gas separative efficiency and effect.
It is understood that the concrete shape of annular compartment 10 is not limited to circle, ellipse, polygon etc. can be constructed
The chamber shape for carrying out spinning movement suitable for air-flow belongs in the scope of annular compartment.
The setting of inlet channel 20 is in 10 bottom of annular compartment, the specific location of inlet channel 20, towards those skilled in the art
Member can according to actual selection, need to construct enter in annular compartment 10 suitable for dust-contained airflow carry out rotation constitute rotary pneumatic
Stream.Optionally, inlet channel 20 is tangentially connected with annular compartment 10, so that dust-contained airflow to enter annular compartment along a tangential direction
In 10, facilitates dust-contained airflow and form swirling eddy in annular compartment 10.
Dust-contained airflow enters from 10 bottom of annular compartment, is oriented to through spiral skew wall 15, forms spiralling swirling eddy,
The top position of outer wall 12 is arranged in dust mouth 14 as far as possible, is able to extend the path that dust-contained airflow carries out rotating centrifugal separation, into
And dust and gas separating effect is further improved, the concrete shape of dust mouth 14, position those skilled in the art can be according to reality
Selection, it be not described in detail herein.
As shown in fig. 6, inlet channel 20 is tangentially-arranged in some embodiments wherein, and the part of inlet channel 20
It extend into annular compartment 10, spiral skew wall 15 surrounds 10 spiral of annular compartment, and spiral skew wall 15 is from initial position to stop bits
At least 180 degree is set, spiral skew wall 15 is divided into leading portion region A and back segment region B, is below the leading portion region A of spiral skew wall 15
As the space that outlet passageway 16 is arranged, and below the back segment region B of spiral skew wall 15 it is then the space for accommodating inlet channel 20,
The lower space of i.e. entire spiral skew wall 15 is not exclusively used as outlet passageway, closes on the upward stop bits of 15 spiral of spiral skew wall
The lower space for setting region is used to that inlet channel 20 is arranged, in this way, make overall structure more compact and reasonable, 15 spiral shell of spiral skew wall
Spinning up end position just is the air inlet air port of inlet channel 20, and dust-contained airflow is directly led by spiral skew wall 15 after entering
To effect, spiral up draft is formed, there is no the separation dead zones of low level.
Of course, the back segment region B of spiral skew wall 15 can also remove, and the lower space of entire spiral skew wall 15 is used to
As outlet passageway, i.e. the top of inlet channel 20 does not have spiral skew wall or inlet channel 20 not to project into annular compartment
In 10.In this way, making all spaces of 15 lower section of spiral skew wall all be used to construct outlet passageway 16, so that the sky of outlet passageway 16
Between volume it is sufficiently large, guarantee air-flow smooth can flow out.
In some embodiments wherein, the upper and lower position of inlet channel 20 and dust mouth 14 exchanges adjustment, inlet channel
20 are located at 10 top of annular compartment, and dust mouth 14 is located at 10 bottom of annular compartment, since inlet channel 20 is in top, ash-laden gas
Stream enters at the top of annular compartment 10, is oriented to through spiral skew wall 15, forms the swirling eddy of spiral decline, similarly, dust mouth
14 are arranged in the bottom position of outer wall 12 as far as possible, are able to extend the path that dust-contained airflow carries out rotating centrifugal separation, and then into one
Improve dust and gas separating effect in step ground.
Wherein, the angle of the helix angle of spiral skew wall 15 should be the smaller the better, however, it is desirable to guarantee the side of inner wall 11
It is open sufficiently large, that is, the outlet passageway 16 constructed wants sufficiently large, and the outlet cross-section area of outlet passageway 16 is sufficiently large, guarantees gas
Stream smooth can flow out, the air inlet cross-sectional area of the outlet cross-section area of outlet passageway 16 at least more than inlet channel 20.
As shown in fig. 6, spiral skew wall 15 surrounds annular compartment spiral 180 degree in some embodiments wherein, in this way,
The angle of the helix angle of spiral skew wall 15 needs to choose larger, and the outlet cross-section area to fully ensure that outlet passageway 16 is enough
Greatly.
In some embodiments wherein, spiral skew wall 15 surround 360 degree of annular compartment spiral, i.e., inlet channel 20 into
Gas air port is the spiral initial position of spiral skew wall 15, and dust-contained airflow has just enter into annular compartment 10 and just starts to carry out spiral,
Dust and gas separative efficiency and effect are preferable.
Of course, since the helix length of spiral skew wall 15 is longer, the angle selection of helix angle can further subtract
It is small, it also can guarantee that the outlet cross-section area of outlet passageway 16 is sufficiently large.Spiral skew wall 15 surrounds the spiral angle of annular compartment 10
And helix angle, those skilled in the art can guarantee that the outlet cross-section area of outlet passageway 16 is at least big according to actual selection
In the air inlet cross-sectional area of inlet channel 20.
The utility model embodiment is explained in detail above in conjunction with attached drawing, but the utility model is not limited to above-mentioned reality
Example is applied, within the scope of knowledge possessed by those of ordinary skill in the art, the utility model ancestor can also not departed from
Various changes can be made under the premise of purport.
