For convenience of description, in definition Fig. 1 and Fig. 2 all component before the principal axis A direction is.As depicted in figs. 1 and 2, a kind of poly-loose wind controlling mechanism of electric fan, comprise that one is provided with 4, ten wind guiding blades 5 of base member and the rotary clamp plate 6 of front mesh enclosure 1, one wind-guiding knob 3, one hollows of middle port 103; Base member 4 from the rear end of front mesh enclosure 1 be fixed on front mesh enclosure 1 port 103, wind-guiding knob 3 from the front end of front mesh enclosure 1 be arranged on front mesh enclosure 1 port 103 being fixedly connected with the rotary clamp plate 6 that is arranged on base member 4 rear ends, the spacing wind guiding blade 5 of base member 4 and rotary clamp plate 6 and wind guiding blade 5 are connected with rotary clamp plate 6; By operation wind-guiding knob 3, wind-guiding knob 3 rotates and drives rotary clamp plate and rotates 6, and rotary clamp plate 6 rotates and drives wind guiding blade 5 and rotates.
Wherein, front mesh enclosure 1 is provided with two screw holes 101 and two locating slots 102 around middle port 103; As shown in Fig. 3 A and Fig. 3 B, the leading flank of base member 4 is provided with two screw poles 401 corresponding with two screw holes 101 and two and two positioning bars 402 that locating slot 102 is corresponding.Base member 4 with the mode be fixedly connected with of front mesh enclosure 1 is: positioning bar 402 is inserted in the locating slot 102 of front mesh enclosure 1, the screw hole 101 of screw lock screw pole 401 and front mesh enclosure 1.
As shown in Figure 4 A and 4 B shown in FIG., wind-guiding knob 3 leading flanks are provided with the operation unit 301 caved in, and wind-guiding knob 3 trailing flanks are provided with polygonal draw-in groove 302 and three screw poles 303; As shown in Fig. 5 A and Fig. 5 B, the leading flank of rotary clamp plate 6 is provided with the polygonal boss 601 that is complementary corresponding to polygonal draw-in groove 302 and three and three corresponding screw pole sleeves 602 that are complementary of screw pole 303.The mode that wind-guiding knob 3 is fixedly connected with rotary clamp plate 6 is: the middle port 411 Corresponding matching ground that polygonal boss 601 passes base member 4 insert in polygonal draw-in groove 302, and screw pole 303 inserts in screw pole sleeve 602 and passes through screw lock.
As shown in Figure 6 A and 6 B, wind guiding blade 5 is provided with blade part 510 and root 520, and root 520 is provided with gear 521; As shown in Fig. 3 A and Fig. 3 B, the trailing flank outer periphery 409 of base member 4 evenly are provided with ten draw-in grooves 404 be used to the U-shaped of the root 520 that blocks wind guiding blade 5, the trailing flank inner circumference edge 410 of base member 4 be provided with ten with ten axis holes 406 that draw-in groove 404 is corresponding; As shown in Fig. 5 A and Fig. 5 B, the leading flank of rotary clamp plate 6 be provided with ten with ten gears 521 tooth bar 603 of the ring-type of corresponding engagement one by one.
As shown in Fig. 2, Fig. 7 A and Fig. 7 B, wind-guiding knob 3 is fixedly connected with and makes rotary clamp plate 6 and the common spacing wind guiding blade 5 of base member 4 with rotary clamp plate 6, specifically, the root 520 of wind guiding blade 5 is embedded in draw-in groove 404, axis hole 406 is inserted in the bottom of root 520, the leading flank outer periphery 606 of rotary clamp plate 6 are plane, and the leading flank outer periphery 606 of rotary clamp plate 6 are covered on the trailing flank outer periphery 409 of base member 4, have jointly prevented the sidesway of wind guiding blade 5; Gear 521 and tooth bar 603 corresponding engagement one by one; Wind-guiding knob 3 rotates and drives rotary clamp plate 6 and rotates, and base member 4 is fixed, and rotary clamp plate 6 rotates and passes through tooth bar 603 and drives wind guiding blade 5 rotations with gear 521.Like this, by operation wind-guiding knob 3, wind guiding blade 5 is changed between He Sanfeng position, wind gathering position, wind guiding blade 5 is adjustable with respect to the flowing angle of the wind of being discharged by fan.
From the wind-guiding angle, 510 need of the blade part of wind guiding blade 5 are from turning 90 degrees, and the design of the length of the length of tooth bar 603 and gear 521 is substantially also to drive wind guiding blade 5 to rotate 90 degree be benchmark (can certainly be bigger than normal or less than normal); As shown in Fig. 3 A, Fig. 3 B, Fig. 5 A and Fig. 5 B, in order to prevent that wind-guiding knob 3 from driving rotary clamp plate 6 and exceedingly rotate and make tooth bar 603 break away from gear 521, limit sliding chutes 605 is set on rotary clamp plate 6, limit sliding chutes 605 is curve bath, take the axle center of rotary clamp plate is axle center, arc length is advisable to drive wind guiding blade 5 rotation 90 degree, traveller 405 is set on the trailing flank of base member 4, traveller 405 passes limit sliding chutes 605, by limit sliding chutes 605, control the slide displacement of traveller 405, thereby reach the purpose that limits rotation displacement.
As Fig. 3 A, Fig. 3 B, Fig. 6 A, Fig. 6 B, shown in Fig. 7 A and Fig. 7 B, for make wind guiding blade 5 can not along its root 520 move axially and do not allow tooth bar 603 directly and outer periphery 409 direct friction of base member 4 impaired, the root 520 of wind guiding blade 5 is provided with an annulus boss 522, annulus boss 522 is between gear 521 and blade part 510, the outer periphery 409 of base member 4 are provided with the stop block 407 of a U-shaped in the outside of each draw-in groove 404, the U-shaped inner side surface of stop block 407 protrudes from the U-shaped inner side surface of draw-in groove 404, due to axis hole 406, are the inner circumference edges 410 that run through base member 4, therefore, the inner circumference edge 410 of base member 4 also be connected with one be positioned at ten axis hole 406 inboards circle enclose muscle 408, when wind guiding blade 5 is assembled on base member 4, annulus boss 522 is placed in draw-in groove 404 and is blocked the outside by stop block 407, and the bottom of root 520 is inserted in axis hole 406 and enclosed muscle 408 and block inboard, and therefore, wind guiding blade 5 can not move axially along its root 520.
As shown in Fig. 3 A, Fig. 3 B, Fig. 5 A and Fig. 5 B, in order to reduce the stressed of screw on screw pole 303, being unlikely to toner screw makes the distance between rotary clamp plate 6 and base member 4 excessive, the front-end face of rotary clamp plate 6 also is provided with four buckles 604, the outer periphery 409 of base member 4 be provided with four with four buckles 604 arcuate socket 403 one to one, the leading flank of rotary clamp plate 6 is covered on the trailing flank of base member 4, and buckle 604 inserts arcuate socket 403 and catches on the leading flank of arcuate socket 403; Due to when adjusting wind guiding blade 5, wind-guiding knob 3 and rotary clamp plate 6 are to rotate together, base member 4 is fixed, and therefore, the corresponding angle of the radian of arcuate socket 403 is the maximum rotation angle that is more than or equal to wind-guiding knob 3.In fact, also can utilize arcuate socket 403 and buckle 604 to limit the rotation angle of wind-guiding knob 3 and rotary clamp plate 6 and reduce the design of traveller 405 and limit sliding chutes 605; Thereby make arcuate socket 403 and buckle 604 play double action.
As shown in Figure 1, for more attractive in appearance, the present invention also is provided with one and is fixed on front mesh enclosure 1 leading flank and entangles the ring 2 of the outer side surface of wind-guiding knob 3, and ring 2 inserts the locating slot 102 of front mesh enclosures 1 by locating fastener 201 location and catches on the trailing flank of locating slot 102.
The present invention is not limited to above-described embodiment, and for example, the gear 521 of wind guiding blade 5 is located between annulus boss 522 and blade part 510, and the tooth bar 603 of rotary clamp plate 6 arranges the outside of outer periphery 606, and only such outward appearance and stability are relatively bad; Therefore, based on above-described embodiment, simple replacement that do not make creative work, should belong to the scope that the present invention discloses.
