Embodiment
Below with reference to embodiment shown in the drawings, the present invention will be described in detail.But the embodiment is not intended to limit
The present invention, structure that one of ordinary skill in the art is made according to the embodiment, method or conversion functionally are wrapped
Containing within the scope of the present invention.
As shown in Figures 1 and 2, the fan structure provided by the present invention for cigarette filter includes impeller 100 and support
Part 200.The impeller 100 has axle sleeve 11 and is formed at some flabellums 12 of the periphery of axle sleeve 11；The support member 200 has
There are housing 21, central shaft 22 and the connecting rod 23 central shaft 22 is fixed in housing 21.
With reference to shown in Fig. 3 and Fig. 4, the axle sleeve 11 runs through to be engaged assembling with the central shaft 22 formed with front and rear
Axis hole 111, and the axle sleeve 11 include it is axially adjacent and in the main part 112 and abutting part 113 that are wholely set, the abutting
Portion 113 to form the chamfering 1131 of curved extension vertically along being gradually tapered up away from the direction of main part 112.The chamfering 1131
The contact area of the rear end of axle sleeve 11 and central shaft 22 can be reduced, and beneficial to the flowing of flue gas.The abutting part 113 is also formed with
Annular end face 1132 perpendicular to axial direction, in order to the machine-shaping of impeller 100.
The impeller 100 rotates inswept diameter of a circle circle between 4.5~5.5mm around its axle center, is preferably arranged to
5.2mm.The spiral angle in the relatively described axle center of the outer rim of the flabellum 12 radially is arranged to 25~45 °；The flabellum 12
Thickness is arranged to 0.35~0.45mm；Except this, lateral margin of the flabellum 12 along its direction of rotation is also formed with wind-guiding face 121, institute
The angle of inclination for stating wind-guiding face 121 is arranged to 20~30 °.Especially, the flabellum 12 exceeds the two of the axle sleeve 11 vertically
End；The front-end geometry of impeller 100 is consistent, to cause the impeller 100 when being assembled on support member 200, is inserted without distinguishing
Direction is connect, in order to install.
Join Fig. 5 and Fig. 6, the housing 21 sets cylindrical and with cigarette filter size to match, the housing
21 form pre-and post perforative gas flow 211.The thickness of housing 21 is arranged to 0.4~0.5mm, herein, to cause consumer
The rotation for experiencing impeller 100 can be observed, the housing 21 is preferably to be made using transparent material.
The central shaft 22 includes the axostylus axostyle 221 arranged successively front and rear vertically, supporting part 222 and fixed with the phase of connecting rod 23
Base portion 223, the central shaft 22 without departing from the housing 21 and the base portion 223 it is equal with the open rearward end of the housing 21
Together.The length of the axostylus axostyle 221 beyond the axle sleeve 11 length and the axostylus axostyle 221 front end it is also radially contracted formed with
Guidance part 2211, to guide the grafting of the impeller 100 to assemble.The axle sleeve 11 and the gap setting of axostylus axostyle 221, the axle sleeve 11
Internal diameter be more than the diameter of the axostylus axostyle 221 and both differences are arranged to 0.3~0.4mm.The supporting part 222 edge from front to back
The internal diameter beyond the axle sleeve 11 is radially gradually increased to, that is, causes the abutting part 113 of the axle sleeve 11 to press on institute backward
State the surface of supporting part 222.The surface of the supporting part 222 is in certain inclination angle with respect to the axially arranged of impeller 100, thereby,
The impeller 100 pressed on backward under airflow function on supporting part 222 and along axle center rotate when, the relative support of axle sleeve 11
The pressure at right angle on the surface of portion 222 is reduced, and then frictional force is reduced.And the roughness Rz on the surface of the supporting part 222
No more than 0.2 μm.
The connecting rod 23 is arranged to three and is uniformly distributed along the periphery of the base portion 223, and the connecting rod 23 is along vertical
Setting is radially extended in central shaft.Especially, the rear end flush of the connecting rod 23 and the housing 21, the connecting rod 23
Cross section is rectangular and causes the size of the side of the square-section to be vertically more than the size of the side of its vertical axial, and should
The size of the side of square-section vertically is less than the development length of the base portion 223 vertically.The connecting rod 23 and base portion 223
Junction be provided with the first rib 231；The connecting rod 23 is provided with the second rib 232 with the joint of housing 21.
In the present embodiment, the supporting part 222 specifically includes in the first round table-like supporting part 2221 and is arranged at
The second supporting part 2222 between one supporting part 2221 and base portion 223, the supporting part 2222 of the first supporting part 2221 and second
It is respectively formed with the first windward side 2223 and the second windward side 2224 to connect vertically.First supporting part 2221 is vertically
Development length be arranged to 0.3~0.5mm, and the angle of inclination of first windward side 2223 to axial be arranged to 40~
45°.Second windward side 2224 extends in cambered surface vertically.According to experiment measuring and calculating, first windward side 2223 and second
Windward side 2224 is engaged the axial air resistance coefficient that can effectively reduce supporting part 222, reduces reverse return air, and then improve impeller
100 rotating speeds.
In other embodiments of the present invention, the also settable protuberance in the front end of the axostylus axostyle 221（It is not shown）, it is described
Protuberance can be fitted close with axis hole 111, and the active force for needing to provide axial direction in installation process is with so that protuberance passes through axle
Hole 111 is so that the impeller 100 is attached on central shaft 22.After completing assembling, the impeller 100 will not be from axostylus axostyle 221 voluntarily
Slide, also avoiding the impeller 100, along axostylus axostyle 221, vibration to the flabellum 12 exceeds the housing forward in rotary course
21。
In summary, using fan structure of the present invention, axial direction of the surface of the supporting part 222 with respect to impeller 100 is set
It is in certain inclination angle to put, to cause impeller 100 i.e. rotatable, and the rear end of the axle sleeve 11 and branch under less airflow function
The kinetic force of friction on the surface of support part 222 is smaller, and the rotating speed of impeller 100 can be improved under same airflow function；And impeller 100 can be extended
Inertial rotation duration, the impeller 100 remains to persistently rotate 1.2~2s under effect of inertia after air-flow disappearance.Also, protecting
Design is optimized to the supporting part 222 on the basis of card support strength, met by first windward side 2223 with second
Wind face 2224 is engaged the axial air resistance coefficient that can effectively reduce supporting part 222, reduces reverse return air, improves 100 turns of impeller
Speed so that obtain more preferable dispersion effect during flue gas gas coming through runner 211, and cause flue gas flowing it is more smoothly with it is steady
It is fixed, improve consumer's sensory experience.
