According to another feature, the invention provides a method of precessing a fan blade. One shaft is rotated and pivotable to a support portion. The shaft is coupled to the pinion such that a deflection caused by movement of the pinion about the ring gear is transmitted to the shaft as a precession of the shaft. The above and other objects, features and advantages of the present invention will become more apparent from 1 is a front left perspective view of an embodiment of the present invention; FIG. 2 is a front right perspective view of an embodiment of the present invention; and FIG. 3 is a right view of an embodiment of the present invention. Fig. 4 is a schematic cross-sectional view showing an embodiment of the present invention; and Fig. 5 is a schematic view of a planetary gear which can be used in combination with an embodiment of the present invention. I: Embodiment 3 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Several embodiments of the present invention provide an improved fan that dissipates or moves air in a space. The preferred embodiment can be used in any device that propels air, such as a fan, space heater, humidified gas, and the like. A particular preferred 201237276 embodiment includes a housing for a portable environmental device, a base, and an internal assembly. The internal assembly includes fan blades that are coupled to a drive train. The drive train includes a single motor coupled to a track gear system that causes precession of the drive train, thereby causing precession of the fan blades about the axis of rotation of the fan blades. The motor, such as an electric motor, has a drive shaft having a first end coupled to the fan blades and a second end coupled to a gear reduction mechanism. The gear reduction mechanism connects the drive shaft to a pinion gear by one or more gears that reduce the rate of rotation of the drive shaft, thereby generating the rotational speed of the pinion. The gear reducer is connected to the pinion via a gear shaft, or the pinion is directly connected to the gear reducer. If a gear shaft is used, it has a distal end that is securely attached to the distal end. The pinion gear is coupled to a ring gear, planet gear or the like on a surface of the rear surface of the non-motor to allow the motor shaft, the fan blade and the drive shaft to pivot and outline a conical shape. The gear reduction mechanism, the pinion and the ring or the planetary gear together form an obstructive gear system. A pivoting surface is coupled to the drive train, preferably to a center of gravity of the pivotable portion. Figure 1 shows a front left side perspective view of the fan 100, which is an embodiment of the present invention. Shown in Fig. 1 is a housing 101 having an opening 102, a protective grill 103 covering the opening 102, and a fan blade 104 positioned behind the protective grid 103. In operation, the fan blade 104 is rotated by a drive shaft that is driven by a drive train having a single motor to propel air through the protective grill 103 and into the area surrounding the fan 100. in. Alternatively, the drive shaft can be precessed about a pivot point such that an axis of the drive shaft outlines a periodic path, which can be a regular depiction of a cone or class 6 201237276 taper Or a symmetrical path. The protective grid 丨〇 3 can be fixed to the casing 101 such that the protective grill 103 is substantially immovable. Alternatively, the protective grill 103 can be fixed to a member, such as a moving motor when the drive shaft is precessed, such that the protective grill 103 also moves. Figure 2 shows a front right side cross-sectional view of a fan embodiment 2A. The components of fan 200 include extensions from a precessional drive train 21 and are coupled to a drive shaft 201 that is coupled to fan blades 205. The end of the precessional drive train 21 稳 is firmly connected to a first support portion. In this embodiment, the first support portion is provided for the housing 208 of the fan 200, and the other end is connected to a first _ The support portion can also be provided for the housing 2〇8 to cause the precession of the drive shaft 201. The precessional drive train 21A includes a single motor 202 that rotates the drive shaft 2〇1. The drive shaft 201 extends from the other side of the motor 202, is coupled to the fan blade 205' to rotate the fan blade 205, and further extends from the other side of the motor 2〇2 to drive the drive shaft 2〇1 to depict a cone Shaped orbital gear unit. The orbital gear arrangement can include, for example, a gear reducer 2〇3 coupled to a ring gear 2〇6 by a pinion 204. The gear reducer 203 uses the drive shaft 201' to provide an output torque on an output shaft 2?7, and the output shaft 207 has a lower rotational speed than the drive shaft 2?1. The output shaft 207 drives the pinion 204 and is in turn engaged with the ring gear 206. Ring gear 206 is securely coupled to housing 208. When the pinion 2〇4 rotates, it outlines a circular path around an inner circumference of the ring gear 206, causing the drive train 210 other than the ring gear 206 to precess, and thus also causing the wind blade 205 precession. To facilitate precession of the drive train 210, the second support portion of the drive train 21 can be 201237276 as a pole. The frame point may be, for example, connected to the motorized casing and the inner portion (4) of the housing 2G8, by pivotally supporting the portion of the shaft 201, or by conventional means. Any other suitable components known in the art are provided. Since the orbital gear unit is firmly connected to the housing 208 by the ring gear, and the training of the train is carried out on the other end, the displacement of the pinion 204 is transmitted to the drive shaft 2 (n, causing the drive (10)]. Precession 'and thus transmitted to the fan blade 2〇5. Fig. 3 shows a right side sectional view of the fan embodiment. The rotating mechanism of the fan is along the front side 3 of the fan 300 with respect to the fan 3_ a rear side The problem solved by this configuration is that when the taper motion is performed, the air is not pushed into the surface of the fan, so that the effect of the fan is not lowered, and the object is not caused on the support surface. As the fan 300 moves around the track through the shape of the tapered surface, even if substantially all of the elements move around the track, the lifting of the drive shaft 3〇1 causes the fan 300 to be above the support surface, pushing it in parallel therewith. Air, rather than entering the support surface. As shown in Fig. 3, the drive shaft 3 (Π, motor 3〇2 and the orbital gear unit 309 including the gear reducer 303, a pinion (not shown) and a ring gear 306 shape An precessional drive train that depicts a movement of the orbiting gear assembly 309 about the track. The drive train is pivotally supported at any position. For example, as shown in Figure 3, the orbital gear assembly 3 The crucible 9 can be a fan housing supported by a ring gear 306, and the drive shaft 3.1 can be concealedly supported by a bushing 307 disposed between the fan blade and the motor 302 and securely coupled to the fan housing. Figure 4 shows a cutaway schematic view of another fan embodiment 400. The horse 8 201237276 reaches 401 driving the drive shaft 402, and the shaft extends from the opposite end of the motor 4〇1. On one side of the motor 401, The drive shaft 4〇2 is coupled to the fan blade 404. On the other side of the motor 401, the drive shaft 402 is coupled to the gear reducer 4〇3. Any suitable conventional gear reducer member may be a gear reducer 4〇3 For use, for example, an embedded spur gear having a different gear speed, a worm drive member, etc. can be used. The gear reducer 403 is provided with an output gear shaft 4〇5 which is based on the effective gear ratio of the gear reducer 403. Proportionally slower than the drive shaft 4〇2 One rate of rotation and its output shaft 4〇5 is coupled to pinion 406 at a distal end. In another embodiment, drive shaft 402 can be directly coupled to pinion 406 via a worm gear or similar gear. Pinion 406 Engaged with the inner circumference of a ring gear 4A. The ring gear 407 is fixed to a first support portion of the fan, such as a "fan housing" (not shown in phantom in Figure 4 in Figure 4 - optional The clutch 411 is engaged with the output gear shaft 4〇5 of the gear reducer 403. The gear reducer 403, the output shaft 405, the selectable clutch 4", the pinion 4〇6 and the ring gear 407 are formed to cause the drive shaft 4〇2 to be precessed Orbital gear unit. The motor 401 is connected to a pivoting point, and the pivoting point is provided with a second support portion socket 409 represented by a ball 408 connected to the matching socket 409 as shown in the sectional view of FIG. One surface is 41〇. In the operation of the embodiment of Fig. 4, the track gear unit motor 401 is provided with a detachable precessional drive train that selectively causes the wind blade to precess about a tapered path. In particular, the motor 4〇1 rotates the drive shaft 402 at a relatively fast rotational speed, thereby rotating the fan blades 4〇4 at the same rate. The gear reducer 403 includes a set of gears that rotate the gear shaft 4〇5 at a deceleration rate of rotation predetermined by the gear speed of the gear reducer 4〇3. When entering, ° 〇§ 201237276 411 can optionally loosen the cn from the ring gear, for example, by destroying the output gear shaft and transferring it to the cymbal, gear shirt, or shifting, gear, so that The loop is engaged and the track gear is released. It is known to those skilled in the art, and can be selectively activated by the user of the fan using any field-specific 411, to know or start the drive shaft 4G2, and the fan blade tree. The tapered orbital motion. When the pinion gear 406 rotates, it engages with the ring gear 407, causing the pinion gear 4〇6 to move around the inner circumference of the ring gear 4〇7, and the pinion yang and the ring gear 407 can be used as the planetary gear system, as described below. Description of the diagram. When the pinion 406 moves in this manner, the output gear shaft 405 and the drive shaft 402 are precessed by a pivot point determined by the ball 408 and the socket 4〇9. The drive shaft 4〇2, the motor 401 and the orbiting gear units 403, 405, 406, 407, 411 together form a selective precession drive train that drives the fan 404 and selectively depicts the orbital gear unit 403 , 405, 406, 407, 411 determines the movement on the orbit. This drive train pivotally supports movement in any suitable position. Figure 5 shows a schematic view of a planetary gear system that can be used in conjunction with an embodiment of the present invention. A ring gear 4〇1 that can be mounted on the fan casing encloses a rotatable sun gear 503 in the middle and one or several planetary gears 502, and the inner circumferential surface of the planetary gear and ring gear 501 and the sun gear The outer circumferential surface of 503 is in contact. One of the planetary gears 502 is configured as a pinion 506 of the embodiment of the precessional drive train as described above. When the pinion 506 is rotated by the output shaft of the reducer gear, for example, when rotating in a clockwise direction, The planetary gear 5〇2 driven by the sun gear 503 advances in the clockwise direction around the inner circumferential surface of the ring gear 5〇1, and the sun gear 503 rotates in the clockwise direction 10 201237276. Although the pinion 506 is on the track between the ring gear 501 and the sun gear 503, it can be securely supported in place.
