(embodiment 1)

Referring to figs. 1 to Fig. 4, the fan FN of the embodiments of the present invention 1 is illustrated.Firstly, referring to Fig.1 and Fig. 2 is illustrated fan FN.Fig. 1 is the perspective view for indicating fan FN.Fig. 1 is the perspective view of fan FN viewed from above.Wind Fan FN is installed on at least part of mask of the face of covering human body.Fig. 2 is the transverse sectional view for indicating fan FN.

As shown in Figure 1, fan FN has impeller PL, motor MT and shell CS.Fan FN is the rotation by impeller PL And utilize centrifugal force to the centrifugal fan of submitting air on the outside of radial RD.Shell CS accommodates impeller PL and motor MT.Impeller PL With multiple blade 1a that circumferentially CD is configured centered on central axis AX.Motor MT rotates impeller PL around central axis AX.Its As a result, impeller PL sends out air towards the outside radial direction RD.In the embodiment 1, central axis AX or more extends.

Shell CS has the air entry A1 of sucking air.Air entry A1 is relative to impeller PL mono- side's side opening of AD in the axial direction. In the embodiment 1, air entry A1 is relative to side opening on impeller PL direction axial direction AD.Air entry A1 is rounded around central axis AX Ground opening.Air entry A1 is opposed on axial AD with motor MT.In addition, the opening shape of air entry A1 is not limited to circle, It can be ellipse, quadrilateral shape etc..

As shown in Figure 1 and Figure 2, shell CS has multiple exhaust outlet B1.Each discharge air of multiple exhaust outlet B1. In addition, Fig. 2 is indicated using the plane orthogonal with axial AD from the fan FN's near the upper end of exhaust outlet B1 when cutting fan FN Section.

Each of multiple exhaust outlet B1 is open to radial RD.Therefore, it is flowed by the rotation of impeller PL from air entry A1 Each the direction radial direction RD outboard exhaust of the air AR1 entered from multiple exhaust outlet B1.As a result, the air quantity in fan FN generates In ability situation identical with the air quantity of the fan fn with exhaust outlet generation ability, with the fan with an exhaust outlet Fn compares, and is capable of increasing the air quantity for the air AR1 being discharged on the outside of from fan FN towards radial direction RD.Thus, it is possible to realize suitable In the exhaust of the bigger air quantity of mask.I.e., it can be realized the exhaust of bigger air quantity.

Also, the fan FN of present embodiment can obtain biggish air quantity compared with previous fan, therefore to wind In the case that fan FN sets air quantity identical with previous fan, it can reduce the revolving speed of motor MT, can reduce fan FN Sound.Also, the fan FN of present embodiment can obtain biggish air quantity compared with previous fan, therefore by fan When FN is installed on mask, compared with the mask for installing previous fan, the dust power of the filter of mask can be improved.In addition, Fan FN can obtain biggish air quantity compared with previous fan, therefore even if the face for being equipped with fan FN is attached in dust In the case where the filter of cover, the air quantity sucked by fan FN also can fully obtain.In addition, air quantity indicates per unit time The amount of air.

Specifically, in the embodiment 1, the number of exhaust outlet B1 is two.As a result, according to embodiment 1, with tool There are three the case where above exhaust outlet to compare, and can be improved the intensity of shell CS.In addition, for example, having by fan FN Two exhaust outlet B1, to can be realized the exhaust of about 1.5 times of air quantity compared with the fan fn with an exhaust outlet. Two exhaust outlet B1 are opposed on radial RD.
