FIELD OF THE INVENTION
The present invention relates to rotary devices, and particularly to a holdable multi-functional rotary device which can be attached to a fan, a massage device, a dust absorbing mask, a shoe brush, a golf rod brush, etc.
BACKGROUND OF THE INVENTION
In the daily life, rotary devices are frequently used at home or offices, such as used in fans, holdable massage devices, dust absorbers, etc. These devices are driven by motors and are used to rotary devices to present specific functions.
Moreover, since the rotary devices driven by motor are used to drive specific rotary bodies. The function thereof is confined and can not be extended. The customers must buy different rotary devices for matching different functional device so that a larger expenditure is necessary and this is not economic.
SUMMARY OF THE INVENTION
Accordingly, the primary object of the present invention is to provide a holdable multi-functional rotary device comprising a casing suitable to be held by users. The interior thereof is formed with a receiving space for arranging a driving unit and a battery. The driving unit has a motor and a driving shaft extending out of the casing. The power of the motor and driving shaft is transferred by a speed change gear set. By changing the speed change gear set, the rotary speed of the driving shaft is changeable. A plurality of rotary pieces are arranged around the driving shaft. The rotary pieces are capable to achieving predetermined effects with the rotation of the driving shaft. Thereby, the whole rotary device can be combined with rotary pieces and the rotary speed of the rotary pieces are adjustable. The rotary pieces can be attached to a fan, a massage device, a dust absorbing mask, a shoe brush, a golf rod brush, etc.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

The holdable multi-functional rotary device of the present invention has a structure illustrated in FIGS. 1 and 2. The holdable multifunctional rotary device comprises a casing 1 suitable to be held by users. The interior thereof is formed with a receiving space 11 for arranging a driving unit 2 and a battery 5. The casing 1 is installed with a power switch 13 for controlling the battery 5 and the driving unit 2 and a bottom thereof is installed with a cover 12 for updating the battery. The driving unit 2 has a motor 21 and a driving shaft 23 which extends out of the casing 1. The motor 21 and the driving unit 2 are driven by a speed change gear set 3 for changing the rotation speed of the driving shaft 23.
Referring to FIGS. 3 and 4, the central shaft and the driving shaft 23 of the motor 21 are firmly secured with a primary gear set 22 and a driven gear set 24 which includes a gear 241. The primary gear set 22 has a larger primary gear 221 and a small primary gear 222. The speed change gear set 3 has a gear frame 31 for axially installing a high speed driving gear set 32 and a low speed driving gear set 32′. The small speed gear set 32′ has a lager driving gear 321 and a small driving gear 322 for matching the rotation speed of the gears. The gear frame 31 is pivoted to the lateral side of the motor 21 and the driving shaft 23 by a pivotal shaft 311. A distal end of the gear frame 31 extends to the exterior of the easing 1 to form with a button 312 (referring to FIG. 1). Thereby, the user can cause the gear frame 31 to swing around the pivotal shaft 311 by pushing the button 312. Thereby, the high speed driving gear set 32 is used to drive the driven gear set 24 by being driven by the primary gear set 22, or the low speed driving gear set 32′ is used to drive the driven gear set 24 by being driven by the primary gear set 22.
At first, with reference to FIGS. 3 and 4, it is illustrated that the driving unit 2 rotates with a high speed. The high speed driving gear set 32 is used to drive the driven gear set 24 by being driven by the primary gear set 22 so that the larger primary gear 221 of the primary gear set 22 is engaged with the high speed driving gear set 32. Meanwhile, the high speed driving gear set 32 is engaged to the driven gear set 24. The high speed driving gear set 32 is engaged to the driven gear set 24 and the motor 21 drives the driving rotary shaft 23 to rotate. Moreover, when the user switches the button 312 to be at the conditions illustrated in FIGS. 5 and 6. The low speed driving gear set 32′ serves to drive the driven gear set 24 by being driven by the primary gear set 22. The large driving gear 321 of the low speed driving gear set 32′ is engaged to the small primary gear 222 of the primary gear set 22. Then, the small driven gear 322 of the low speed driving gear set 32′ is engaged to the driven gear set 24. The rotation number of gears at the rear section can be reduced by increasing the number of the teeth of the gear so that the motor 21 can drive the driving shaft 23 with a lower speed. Moreover, the casing 1 can be installed with a guide groove 14 which is matched with the swinging range of the gear frame 31 so as to guide the gear frame 31 to swing according to predetermined moving trace. Moreover, the button 312 is installed with a positioning piece (not shown) for swinging the gear frame 31 to a predetermined point to sustain the speed change gear set 3, motor 21 and the driving shaft 23 have a steady driving relation.
Thereby, when the holdable multi-functional rotary device of the present invention is used, as illustrated in FIGS. 7 and 12, a plurality of rotary pieces 4 are engaged to the driving shaft 23 so as to achieve some predetermined effect with the rotation of the driving shaft 23. Moreover, the user may update rotary pieces 4 as required. As shown in the FIG. 7, the user may use the rotary pieces 4 made from soft blades to be assembled around the driving shaft 23 so that the whole holdable multi-functional rotary device 41 becomes a holdable fan. Referring to the FIG. 8, the user may engage the rotary pieces 4 with the massaging covers 42 on the driving shaft 23. Then the eccentric shaft 421 of the massaging cover 42 is engaged to the driving shaft 23 so that the whole rotary device is holdable. As shown in the FIG. 9, a rotary piece 4 with dust absorbing mask 43 is engaged to the driving shaft 23, and the spiral fan 431 of the dust absorbing mask 43 is engaged to the driving shaft 23 so that the whole dust absorbing mask 43 becomes a holdable dust absorbing mask 43. As shown in the FIGS. 10 and 1, the rotary piece 4 can be installed with a soft brush cover 44 or a hard brush cover 45 and then is installed to the driving shaft 23 so that the soft brush cover 44 and hard brush cover 45 rotates with the rotation of the driving shaft 23. Thereby, the whole rotary device becomes a shoe brush or a sole brush. Moreover, referring to FIG. 12, the rotary piece 4 with lateral brush cover 46 is engaged to the driving shaft 23 so that the whole rotary piece 4 becomes a golf rod brush.
The holdable multi-functional rotary device comprises a casing suitable to be held by users. The interior thereof is formed with a receiving space for arranging a driving unit and a battery. The driving unit has a motor and a driving shaft extending out of the casing. The power of the motor and driving shaft is transferred by speed change gear set. By changing speed change gear set, the rotary speed of the driving shaft is changeable. A plurality of rotary pieces are arranged around the driving shaft. The rotary pieces are capable to achieving predetermined effects with the rotation of the driving shaft. Thereby, the whole rotary device can be combined with rotary pieces and the rotary speed of the rotary pieces are adjustable. The rotary pieces can be attached to a fan, a massage device, a dust absorbing mask, a shoe brush, a golf rod brush, etc.
Although the present invention has been described with reference to the preferred embodiments, it will be understood that the invention is not limited to the details described thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
