Airflow function dust in groove M1.Therefore, the dust in groove M1 not only from region D2, also from
The part being contained in the region D1 being difficult to remove also is removed.As it has been described above, by by nozzle 71
Opening 71a is disposed in the front projection region of the stream R making suction inlet main body 11 connect with suction inlet joint 13 to be come
Improve dust catching efficiency.It addition, in the sucking mouth 6 of the present embodiment, although nozzle opening 71a entirety comprises
In the D1 of region, but also need not comprise entirety, it is possible to so that a part of nozzle opening 71a is contained in stream
In the front projection region of road R.
Fig. 8 is the figure of the passage of the air-flow being shown schematically in the interior flowing of above-mentioned sucking mouth.Such as Fig. 8
Shown in, extraneous gas (atmospheric pressure) is attracted from air entry 70 (aperture area A_70), by filtering
Device portion 80 (front surface area A_80 (hereinafter referred to as aperture area)), downstream, inflow filter portion 80
Space T (pressure (static pressure) P_T).Additionally, from space T by nozzle 71 from nozzle opening 71a
(aperture area A_71a) is discharged into sealed chamber P (pressure (static pressure) P_P).On the other hand, from attraction
The extraneous gas that mouth 91 is attracted, flow into motor receiving room S, by cooling down motor 40 behind filter portion 85
(when motor 40 drives), from the opening 14b (reference of the first linking part 14 being arranged at suction inlet joint 13
Fig. 4) flow in stream R.Here, each of stream from air entry 70 to nozzle opening 71a is made
Partly (air entry 70, filter portion 80, nozzle opening 71a) aperture area (A_70, A_80,
The relation of size A_71a), meets A_70 ＞ A_71a, A_80 ＞ A_71a.Specifically, at this
In the sucking mouth 6 of embodiment, A_70=260mm2, A_80=245mm2, A_71a=80mm2.Separately
Outward, about air entry 70, filter portion 80, nozzle opening 71a, the opening in various piece is multiple
In the case of, as long as its summation meets above-mentioned relation.
In order to make fully to act on the dust of swept surface M from the air-flow of nozzle opening 71a discharge, need
Air-flow at a high speed.Due to air-flow be the upstream space T by nozzle 71 pressure P_T and sealed chamber P in
Pressure P_P between pressure differential and produce, the most as far as possible raise nozzle 71 upstream space
The pressure P_T of T.That is, reduce extraneous gas (atmospheric pressure) and pass through filter portion to sky from air entry 70
Between T flowing time pressure decline (atmospheric pressure-P_T), can effectively increase in space T and sealed chamber P
Pressure differential (P_T-P_P).The degree declined due to pressure depends on flow path cross sectional area (aperture area),
In the sucking mouth 6 of the present embodiment, A_70 ＞ A_71a, A_80 ＞ A_71a, make the upstream of nozzle 71
Increase can be formed with the pressure differential (pressure differential (P_T-P_P) in space T and sealed chamber P) in downstream
High velocity air.
If it addition, sucking extraneous gas and blow out from nozzle opening 71a, then along with the amount of the air-flow blown out
(flow) increases the pressure P_P in sealed chamber P and rises (vacuum degree reduction).As it has been described above, from nozzle
In the air-flow of opening 71a blowout is the pressure P_T and sealed chamber P of the upstream space T by nozzle 71
Difference (pressure differential) between pressure P_P and produce, if therefore pressure P_P in sealed chamber P rises (negative
Pressure degree reduces), then pressure differential (P_T-P_P) reduces, and blowout flow velocity reduces.Therefore, if nozzle opening
The aperture area A_71a of 71a is excessive, then cannot obtain can fully act on swept surface M dust and
There is the air-flow of high flow velocities.In this case, adjusted by a part of plug nozzle opening 71a
Whole aperture area A_71a, thus increase the negative pressure in sealed chamber P, make pressure differential (P_T-P_P) increase
Big.In particular, it is preferred that make pressure differential (P_T-P_P) at more than 380Pa.
Additionally, it is preferred that as plug nozzle opening 71a a part of, be attended by the short of nozzle opening 71a
In the case of shaft length L3 (with reference to Fig. 6) reduces, make between nozzle opening 71a and swept surface M away from
L6 ＜ 3 × L5 is met from L4 (with reference to Fig. 6).It addition, by sucking extraneous gas from nozzle opening 71a
Blowout, the pressure P_P in sealed chamber P can rise (vacuum degree compared with the situation not sucking extraneous gas
Reduce), but sucking mouth can be weakened accordingly and be adsorbed in the power of swept surface M, therefore improve operability.
As it has been described above, from the flow velocity of nozzle opening 71a blowout air-flow, be the upstream space by nozzle 71
The pressure differential (P_T-P_P) between pressure P_P in the pressure P_T and sealed chamber P of T and determine,
But in the case of the pressure P_P in sealed chamber P is insufficient to low (vacuum degree is the highest), even if sucking
Extraneous gas also discharges from nozzle opening 71a, does not the most act on the dust of swept surface M but occurs to turn
To and towards stream R flow.Accordingly, it would be desirable to for the airtight airtight holding unit keeping sealed chamber P.
Generally for keeping airtight, need make the opening drawing an airflow in sucking mouth i.e. sucking mouth and cleaned
Space between face is sufficiently small.Such as, in the conventional sucking mouth described in patent documentation 2, not to holding
Airtight account for, although possess and be fixed on the hairbrush body before and after sucking mouth (referring for example to patent documentation 2
