6. overall umbrella motion mode driver (Figure 18): engage a driver at umbrella handle or handle of umbrella, keeps overall umbrella shape to carry out pulling down the reciprocating motion of wind and upwards air draught.Using all support members of overall umbrella shape as driving member, drive to umbrella cover, be equivalent to the reciprocating motion that umbrella cover carries out pulling down wind and upwards air draught.Owing to being the motion of overall umbrella shape, it is most straightforward procedure.Although overall umbrella shape motion, perhaps, drop-down wind direction is not optimum orientation, but has and draw wind effect, especially arc umbrella cover successful: during pull-up, arc umbrella cover is streamlined--wind direction ecto-entad of calling prisoners in after letting them out for exercise, time drop-down, wind direction is from inside to outside, moves up and down continuously--feel cool effective.In order to extensive use: driver is driven seat as reciprocating motion, only needs to carry driving seat, just can engage common umbrella, make common umbrella become at once and draw wind umbrella.This method is applicable to various umbrella, and driving method is also varied, as long as it is all right to realize " drop-down and pull-up moves back and forth ".Such as: utilize above-mentioned ratchet mechanism or cam mechanism or electronic or cylinder, make and drive seat, to be opened an umbrella driving member by entirety, drive umbrella cover to be pulled upward to a high position, trigger commutation manually or automatically, be pulled down to low level, move back and forth.In particular cases, also by driving seat hang upside down (Figure 19), can engage with the umbrella point driving the engaging lever of seat and entirety to open an umbrella, transmit power and move back and forth to umbrella cover.Drive seat can be designed to according to different umbellate forms, the frequency of adjustable reciprocating stroke and drop-down/pull-up speed and drop-down/pull-up, is adapted to extensive use

7. driver reciprocating stroke: stroke is little-wind is little, stroke is large-and wind is large.Hide scope with what do not affect umbrella, have again suitable air quantity to be advisable simultaneously.In same air quantity situation, the stroke that arc umbrella cover needs than flat umbrella cover is little.Usual employing small movements: for the conventional umbrella cover of diameter 80-110cm, reciprocating stroke is about 10-20cm, also can according to circumstances determine voluntarily.For the driver of Electronic control, the installation site of limit sensors or normally-closed contact switch can be regulated, control reciprocating stroke.According to lever principle, the position also by changing the umbrella frame strong point changes corresponding movement travel, the strong point from end face center more close to, when strut support angle is identical, the reciprocating stroke required for same motion amplitude less (Figure 20)

8. driver drop-down/pull-up motion speed: drop-down speed waves cattail leaf fan hurry up than hand, to feel having suitable air quantity to be advisable.Usually select drop-down speed faster than pull-up speed, lower the temperature with drop-down pectinid.The drop-down speed of umbrella is about 20cm/s, and drop-down and velocity rate that is pull-up converts time ratio to: usually select 1:3 to 1:10, namely during fall times 0.5 second, and corresponding 1.5 to the 5 seconds pull-up time.If arc umbrella cover-air quantity is large, drop-down speed and drop-down/pull-up velocity rate can reduce.As special case: drop-down can be identical with the speed of pull-up, the velocity rate (time ratio) of drop-down/pull-up can be 1:1, namely drop-down identical with the time of pull-up.For the umbrella that end face arc is very large, even can conversely, pull-up speed is faster than drop-down speed, lowers the temperature with air draught from outside to inside.Also can according to circumstances regulate voluntarily.For the driver of Electronic control, the electric moter voltage moving back and forth drop-down/pull-up can be regulated, control the speed moving back and forth drop-down/pull-up

9. usually select the respiratory rate being comparable to people during driver reciprocating frequency: Give body temperature lowering.About 10-20 time per minute.Be advisable so that human body sensory is comfortable.Also can according to circumstances regulate voluntarily.For the driver of Electronic control, the output waveform of electronic control component can be regulated, control the cycle and the dutycycle that move back and forth output voltage

10. umbrella cover moves back and forth angle: feel have wind to be advisable with human body upper body, the radian changing the length of strut or the stop position of supporting point position or strut sleeve or umbrella frame can change the inclination angle of umbrella cover, preferably use arc umbrella cover, the direction of motion of umbrella cover is designed to towards the upper body direction of human body

11. umbrella frames use elastomeric material, utilize the elasticity of umbrella frame to drive umbrella cover, auxiliary restoring movement.After the external diameter of fixing umbrella, the strong point of adjustment strut can change flexible direction, and flexible direction can change wind direction

Elastic method 1 uses extension spring restoration characteristics: umbrella frame has longitudinal elasticity, and external force drives umbrella frame camber normality by strut, and when drop-down, umbrella frame returns to linear (the shortest position of length)-power-assisted from arc

Elastic method 2 uses bistable state sheet spring umbrella frame (Figure 21): similar a kind of elasticity hair fastener, two ends relative positioning (fix by umbrella cover center, one end, other end umbrella cover external diameter limits), external force, by crossing after critical point bullet in the middle part of strut band moving plate spring umbrella frame to steady state point-its normal orientation, offsets part sheet spring force-to top dead centre (figure is left) with secondary spring after upwards crossing critical point; External force drives umbrella frame to drive the drop-down pectinid of umbrella cover (figure is right) by secondary spring gusset spring after critical point excessively downward in the middle part of strut band moving plate spring umbrella frame jointly.Adjustment strut supporting point position and stay length can change the elasticity direction of sheet spring, namely change wind direction

12. umbrella covers can be designed to shrink rear formation a lot of little folding (similar folding fan and the old-fashioned umbrella, made of oiled paper and bamboo frame), in reciprocating motion, the initial or terminating point using the extreme position stretching or shrink as image change, makes and becomes dynamic picture, increase attractive in appearance, attract to pay close attention to

13. umbrella covers can use elastomeric material, and the elasticity of umbrella cover self has auxiliary recovery driving effect to drop-down (closing one's umbrella) action; Umbrella cover relies on natural resiliency to stretch and contraction, keeps the smooth air quantity effect of going for a drive-increase of umbrella cover (because common umbrella closes one's umbrella the-lax buffering of umbrella cover-counteracting part air quantity) time drop-down; During reciprocating motion, keep umbrella cover smooth, can make umbrella cover image complete clear (because common umbrella close one's umbrella-umbrella cover is lax-the irregular depression of umbrella cover); Simultaneously in reciprocating motion, according to stretching, extension and the contraction of umbrella cover self, the initial or terminating point using the extreme position stretching or shrink as image change, makes and becomes dynamic picture, more attractive in appearance, attracts to pay close attention to

14. umbrella cover peripheral edges (umbrella limit) install the flexible decorative product (Figure 22) of air curtain, activity such as palpus fringe, shirt rim etc.: time drop-down, air quantity is drawn in the topside area-increase floating-increase umbrella, the swing of flexible decorative product, has the effect of putting on airs, more noticeable

15. is self self-movement owing to drawing wind umbrella, tilts and upset does not affect action.So, draw wind umbrella can lay use by any direction.Such as: draw wind umbrella level or vertically place, mounting bracket or hanger, just can become umbellate form fan or umbellate form ceiling fan: by the motor drive mode example of Figure 10 driver, half-twist, horizontal positioned, with the top of support fixing umbrella, it is exactly the positive original umbellate form electric fan (Figure 23) of umbrella-type.In order to attractive in appearance and practical, the drive motors be arranged on umbrella handle or handle of umbrella moved to umbrella point direction (umbrella handle top bearing of trend) from handle of umbrella direction, can be evolved and become umbellate form fan (Figure 24 or Figure 25).Positive umbrella-type (Figure 24): strut sleeve is front, and umbrella cover is rear, and strut sleeve moves back and forth, and umbrella cover center is fixed.Anti-umbrella-type (Figure 25): umbrella cover is front, and strut sleeve is rear, and umbrella cover center moves back and forth, and strut sleeve is fixed.At the terminal sensor installation of reciprocating stroke or normally-closed contact, the control circuit (Figure 14 or Figure 15) of motor driver can be adopted.Directed driven adopts leading screw-guide rail or leading screw-guide rod or leading screw-directed piston isoline guidance mode, the rotation of motor is changed into rectilinear motion, can use DC micro-motor, can roll over umbrella and carry by picture
