Description




BACKGROUND OF INVENTION




1. Field of Invention




The present invention is related to a nail dryer.




2. Related Prior Art




Many ladies like to wear nail polish on their nails and more particularly finger nails for aesthetic reasons. However, it takes a long time for the nail polish to dry in the air naturally. Therefore, a lady has to waste considerable time waiting for the nail polish on her nails to dry. To avoid such waste of time, some nail dryers have been devised to expedite drying of the nail polish on nails.




Sometimes, ladies dry nail polish on their nails with a hair dryer. Use of the hair dryer to dry the nail polish requires some skills. If the hair dryer is positioned too far from the nail polish, a small portion of hot air sent from the hair dryer can contribute to the drying of the nail polish. If the hair dryer is positioned too close to the nail polish, the nail polish will be wrinkled by strong air sent from the hair dryer.




For example, Taiwanese Patent Publication No. 209346 discloses a conventional nail dryer that includes a handle extending from a shell. A light source that can emit ultra-violet light is installed in the shell. The shell defines a slot through which ultra-violet light emitted from the light source can spray. After wearing nail polish on her finger nails, a lady can hold the handle with her hand so that the ultra-violet light shines on her finger nails in order to cure the nail polish. This conventional nail dryer however may cause a problem on human health, i.e., the ultra-violet light may hurt a user's skin.




The present invention is therefore intended to obviate or at least alleviate the problems encountered in the prior art.




SUMMARY OF INVENTION




It is an objective of the present invention to provide a nail dryer that can expedite drying of nail polish on a nail.




It is another objective of the present invention to provide a nail dryer that can expedite drying of nail polish on a nail without wrinkling the nail polish.




According to the present invention, a nail dryer includes a housing for contacting a user's fingers and an air stream generation unit received in the shell for generation of an air stream in order to dry nail polish the user's nails.




The housing defines a plurality of vents and a plurality of apertures. Air leaves the housing through the vents and enters the housing through the apertures.




The housing includes two shells each defining a plurality of apertures. One of the shells includes a plurality of hooks formed thereon and the remaining one of the shells includes a corresponding number of recesses defined therein for receiving the hooks.




The air stream generation unit includes a motor and a propeller connected with the motor. The motor is connected with a DC power supply through a circuit. The circuit includes a switch.




The housing includes a seat on which the motor is mounted. The seat includes a plurality of plates projecting from one of the shells. Each of the plates of the seat includes an edge complementary to the motor.











Other objectives, advantages, and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the attached drawings.

DETAILED DESCRIPTION OF EMBODIMENTS




Referring to

FIGS. 1-3

, a nail dryer according to the present invention includes a housing


100


for containing other elements. The housing


100


looks like an American football except for including two flat ends. The housing


100


is assembled from two shells


10


and


20


similar to each other in profile.




The shell


10


includes an external side


11


that is exposed when the shells


10


and


20


are engaged with each other and an internal side


12


that is concealed when the shells


10


and


20


are engaged with each other. The shell


10


defines a plurality of apertures


13


through which air can enter the housing


100


. The shell


10


defines two holes


14


near an edge thereof. The holes


14


may be replaced with two recesses defined in the internal side


12


. The shell


10


defines three slots


15


in one end thereof. The shell


10


defines a cutout


19


in the edge thereof.




The shell


20


includes an external side


21


that is exposed when the shells


10


and


20


are engaged with each other and an internal side


22


that is concealed when the shells


10


and


20


are engaged with each other. The shell


20


defines a plurality of apertures


13


through which air can enter the housing


100


. The shell


20


includes two hooks


24


formed thereon near an edge thereof.




The shell


20


defines three slots


25


in one end thereof The shell


20


defines a cutout


29


in the edge thereof.




The shells


10


and


20


can be assembled. The holes


14


receive the hooks


24


. As best seen in

FIG. 1

, the slots


15


and


25


together make longer slots that function as vents through which air leaves the housing


100


. The cutouts


19


and


29


together make a hole to be described.




The nail dryer includes an air stream generation unit consisting of a motor


30


received in the housing


100


and a propeller


31


connected with the motor


30


. The motor


30


can drive the propeller


31


to generate the air stream.




A seat


26


is formed on the shell


20


. The seat


26


includes two plates


261


projecting from the internal side


22


of the shell


20


. The plates


261


are shaped corresponding to a profile of the motor


30


so that the motor


30


can be stably mounted on the plates


261


.




The motor


30


is connected with DC power supply


273


through a circuit. The DC power supply


273


consists of two batteries received in a box


27


formed on the internal side


22


of the shell


20


. Two metal strips


271


and


274


are mounted on a wall of the box


27


. A metal strip


272


is mounted on an opposite wall of the box


27


. The circuit includes a switch


28


, a wire


282


leading from the switch


28


to the metal strip


274


, a wire


284


leading from the metal strip


271


to the motor


30


and a wire


285


leading from the motor


30


to a wire


283


leading from the switch


28


. The circuit will not be further described in detail, because it is conventional and not the spirit of the present invention. The switch


28


includes a lever


281


. The switch


28


is installed in the shell


10


so that the lever


281


extends through the hole made by the cutouts


19


and


29


.




Referring to

FIG. 4

, a user (not shown) can hold the nail dryer with one hand. The user's thumb contacts an area of the shell


20


in which the apertures


23


are defined while the other fingers contact an area of the shell


10


in which the apertures


13


are defined. The motor


30


drives the propeller


31


in order to expel air from the housing


100


through the vents made of the slots


15


and


25


. This causes air to flow into the housing


100


through the apertures


13


and


23


. This air stream is strong enough to expedite the drying of the nail polish and is soft enough not to wrinkle the nail polish.





FIG. 5

shows another way to hold the nail dryer.




The present invention has been described through detailed illustration of the preferred embodiment thereof. Those skilled in the art can derive many variations from the preferred embodiment without departing from the scope of the present invention. Therefore, the preferred embodiment shall not limit the scope of the present invention. The scope of the present invention can only be defined in the attached claims.
