ABSTRACT OF THE DISCLOSURE
A pulsator for a hair dryer which is characterized by a rotator having inclined vanes which is mounted for rotation between a hair dryer's fan and air outlet to provide a whirling air flow which lifts and separates hair being dried and styled with a pulsating frequency,
A pulsator for a hair dryer which is characterized by a rotator having inclined vanes which is mounted for rotation between a hair dryer's fan and air outlet to provide a whirling air flow which lifts and separates hair being dried and styled with a pulsating frequency,
Description
~ 3 3 Background of the Invention With hair dryers currently on ~he market, particularly the very popular hand-held hair dryers, the air flow is often either too strong to permit proper styling of the hair as i~ is dried or so gentle that i~ takes much too long to properly dry the hair.
Therefore, there is a definite need for a low-cost hair dryer which is more effective in drying the hair while simultaneously facilitating controlled styling thereof. This new hair drying/styling technique is made possible by a whirling air flow which, with a pulsating action, lifts and separates the hair being dried and styled.
Summary of the Inve o_ The present invention is directed to a hair dryer having a pulsator ~eature which may either be built into the air outlet end of a hair dryer or be provided in the form of an accessory which is readily attachable to the air outlet end of a hair dryer.
In either form the pulsator feature is characterized by a rotator which is mounted for free rotation forwardly of the hair dryer fan and which has a unique arrangement of in-clined vanes which cause rotation of the rotator when the hair dryer fan is operating and which also serves to convert the normal straight-ahead fan air flow into a whirling and pulsating outlet air flow which, with a pulse beat, lifts and separates the hair being dried and styled.

Detailed Descr~tion of the Invention As illustrated in Fig, 1, a pulsator attachment lO
embodying the invention is shown assembled on the air outlet end of a suitable hand-held hair dryer 12 having a cylindrical body portion 14 with a handle 16 pivotally mounted in a known manner between a pair of lugs 18, which depend from the rear end of the body portion 14. As showm in Fig. 3, an electric mo~or 20, a fan 22 operable thereby, and a heater assembly 24 are disposed within the body portion 14 of the hair dryer 12 to provide a straight-ahead flow of heated air toward the air outlet end thereof which is provided with a safety screen or grid 24. A power cord 28 (Fig~ 6) extends through the handle 16 for connection to the electric motor 20 and the heater assembly 24 in a known manner~ A slide switch 30 is provided on the handle 16 for controlling operation of the fan motor 20 and the heater assembly 24.
The pulsator attachment 10 is characterized by a sleeve-like housing 32 having a reduced diameter rear portion 34 which is adapted to be telescopically fitted over the air output end of the body portion 14 of the hair dryer 12~ Inte-grally formed7 as by molding, on the inner surface of the sleeve-like housing 32 just forwardly of ~he reduced diameter portion 34 is a three-armed spider support member 36 having three radial arms 40 and a hub portion 38 disposed at the axial center of the sleeve-like housing 32. Each arm 40 of the spider support 36 (Figs. 3 and 4) has a rear or trailing edge 42 (Fig, 5) with the inner portions thereof adjacent the hub portion 38 being disposed in a plane normal to the axis of the hub portion 38, as are the entire leading edges of the arms 40 and with the radially outer portions of the trailing edges 42 being inclined rearwardly as at 44 (Fig~ 3), for increased stability. As best shown in Fig~ 5, the hub portion 38 is prov;ded with a central bore 46 which has a bushing 48 press-fitted therein, wh~ch bushing 48 has an enlraged h~ad portion 50 pro~ided at its rear end, As the spider support 36 is normally disposed in somewhat close proximity to the heater assembly 24, a complementary three-armed metallic clip 52 3 ~ ~
(Fig. 4) is provided for the spider support 3~ as an aid in dissipating heat from the heater assembly 2~. A 'bored center portion 5~ of the three-armed clip 52 is trapped beneath the bushing head 50 (Fig. 5) with each radial arm 56 o~ -~he clip 52 having rear portions 58 which extend over the planar portions of the trailing edges 42 of the spider support arms 40 and side portions 60 which extend Eorwardly over the sides of the arms 40 of the spider support 36.
A stub shaft 62 (Fig. S) is freely rotatable in the bushing 48 and has one end projecting forwardly o~ the spider support 36 and the opposite rear end having a collar 64 press-fitted thereon, a washer 55 being provided between the stub shaft collar 64 and the enlarged head 50 of the bushing 48.
The stub shaft 62, therefore, is freely rotatable about a longitudinal axis centered in the sleeve-like housing 32 of the pulsator attachment 10.
The pulsator attac'hment 10 is also characterized by a rotator 70 having a cylindrical outer wall 72 which is slight-ly smaller in diameter ~han the inner surface of the sleeve-like housing 32. The rotator 70, as best shown in Figs~ 2 and 3, is also characterized by a centrally positioned hub 74 having a rearwardly opening central bore 76 (Fig. 5) which is press-fitted on the forward end of the stub shaft 62, a washer 78 being provided between the rotator hub 74 and the spider support hub 38. The rotator 70, which preferably is molded in one piece, is further charac~erized by a series of parallel vanes 80, with the center vane 82 passing through the center or axis of the rotator 70 and having the rotator hub 74 ~ormed therewith. As best shown in Fig, 3, all of the vanes 80, including vane 82, are inclined forwardly in the same direction and at the same angle of approximately 30 to the horizontal.
The rotator 70 is further characterized by a single vane 84 which is disposed at right angles or normal to the vanes 80, 82 and which also extends through the center of the rotator 70 whereby the rotator hub 74 is also formed in association therewith. As viewed in Fig. 2, the portion 84a of the vane 84 disposed above the rotator hub 74 is inclined rearwardly and to the right at an angle of approximately 30 to the vertical whereas the por-tion 84b of the vane 84 disposed below the rotator hub 74 is inclined rearwardly and to the left, also at an angle of approximate'ly 30~ to the vertical.
~ ith the particular vane arrangement disclosed herein for the rotator 70, the generally straight-ahead air flow from the fan 22 engages the rear surfaces of the inclined vanes 80, 82, 84 to provide clockwise rotation of the rotator 70, as viewed in Figs. 2 and 6, with the vane configuration providing a whirling, pulsating outlet air flow, as is bes~ indi.cated by the dotted line air flow showing 88 in Fig. 6. ~s prevlously noted herein and as shown by the arrows in Fig~ 6, this whirling air flow provided by the pulsator attachment lO provides alter-na~ing lifting, separating and release of the hair being dried,whereby to provide lifting and separating on a pulsating basis and therefore both more effective drying and better controlled styling of the hair~
It is noted that the reduced diametPr rear portion 34 of the sleeve-like housing 32 is provided with a series of circumferentially spaced, rearwardly opening slots 90 which facilitate mounting of the pulsator attachment 10 on the air outlet end of the hair dryer 12.
It is further noted that a spider support member for a rotator such as rotator 70 could be provided or lntegrally ~ormed in the air outlet end of a hair dryer housing with a rotator such as rotator 70 bei.ng rotatably supported thereon within the main housing of the hair dryPr. Therefore, the pulsator feature disclosed herein may, if desired, be provided as a permanent part of a hair dryer structure rather than merely as an accessory for attachment thereto.
~ hile there have been shown and/or described two alternative embodiments of the present invention, it will be apparent to those skilled in the art that various changes and modi-fications may be made without departing from the invention in its broader aspects and it is, therefore, contemplated in the appended claims to cover all such additions, changes and modifications that fall within the true spirit and scope of the present invention,
Therefore, there is a definite need for a low-cost hair dryer which is more effective in drying the hair while simultaneously facilitating controlled styling thereof. This new hair drying/styling technique is made possible by a whirling air flow which, with a pulsating action, lifts and separates the hair being dried and styled.
