Description
FIELD OF THE INVENTION
[0001] The present invention generally relates to an electric iron
additionally generating anions for smoothening ladies hair.
BACKGROUND OF THE INVENTION
[0002] Men and women use many kinds of appliances to care for their
hair, such as hair dryers and various types of irons. All these
instruments heat and damage the hair. Repeated exposure to heat and
such stress makes the hair rough. To protect their hair, many women
use additional hair protecting agents. The present invention is to
provide an electric iron for hair straightening without damaging
the hair.
DESCRIPTION OF THE PRIOR ARTS
[0003] From U.S. Pat. No. 1,455,696 to Wright to U.S. Patent
Publication US 2003/0052115 to Leung, all the prior art related
with electric irons for hair treatment has no parts for producing
anions.
[0004] U.S. Pat. Nos. 5,939,059 and 6,264,931 to Franklin, et al.
illustrate a 2-in-1 conditioning shampoo includes an anionic
surfactant and a cationic hair conditioning agent. U.S. Pat. No.
5,714,446 Bartz, et al. discloses hair conditioning shampoo
compositions comprising from about 5% to about 50%, by weight, of
an anionic surfactant component. U.S. Pat. No. 5,679,330 to Matsuo,
et al. illustrates a shampoo composition containing an anionic
surfactant. U.S. Pat. Nos. 5,456,863 and 5,358,667 to Bergman
illustrates a conditioning shampoo composition containing an
anionic cleansing surfactant. U.S. Pat. No. 5,409,628 Heinz, et al.
discloses a hair shampoo composition presenting improved
hair-conditioning properties, comprising of at least one anionic
surfactant. U.S. Pat. No. 5,077,041 to Yamashina, et al. discloses
a shampoo composition that includes an anidoamine-type amphoteric
surface-active agent. U.S. Pat. No. 4,247,538 Barker illustrates
aqueous compositions useful for shampooing, cleaning and
conditioning hair and containing an amphoteric shampoo base, a
cationic surfactant and an anionic macro colloid polymer. U.S. Pat.
No. 4,001,394 to Fogel, et al. discloses a shampoo, crme rinse
composition containing an anionic detergent.
[0005] As shown in the later part of the prior arts, the anion does
a key role in conditioning hair. However, none of the prior art
regarding hair irons illustrates a method of producing and
introducing anions to the hair while treating with electric hair
irons as shown in the present invention.
SUMMARY OF THE INVENTION
[0006] It is the purpose of the present invention to provide an
electric iron for straightening women's hair that is capable of
producing anion. The electric iron has an electron generator
embedded on one of the handle of pivotally connected handles.
Electrons are generated from the inside of an AC/DC converter and
transferred to the end of the cathode line, which is equipped with
a number of thin carbon fiber filaments at the opposite end, that
meets air and generates oxygen anions. Oxygen anions produced there
come into contact with the hair and make the hair smooth and
silky.

DETAILED DERCRIPTION OF THE PREFERRED EMBODIMENT
[0012] FIG. 1 is a perspective view of the anion-generating
electric hair straightening iron (1) of the present invention. The
iron (1) is comprised of two handles (2) pivotally connected by a
hinge (3), which is installed close to one end (4) of the handles,
and two heating blades (5) developed at the other ends of the
handles (2). The handles (2) have limitations of opening by the
shape of one end (4) of the handles (2). A spring (6) in the spring
holder (7) keeps the handles open when not in use. An on/off switch
(8) and a heating blade (5) temperature controller (9) are located
on one end of the upper handle (2-U) and connected to 120/220V
multi-power code (10). An electron generator (11) is embedded in
the lower handle (2-L). A circuit checking light (23) through the
window (12) at the side of the lower handle (2-L) indicates
operation of the electron generator (11). Pluralities of holes (13)
are developed along the side part of lower handle (2-L) below the
lower heating blade (5-L).
[0013] FIG. 2 is an exploded inside plane view of the lower handle
(2-L) and the lower heating blade (5-L). FIG. 3 is an exploded side
view of the lower handle (2-L). The lower handle (2-L) is comprised
of a plastic housing (14-L), a plastic handle cover (15-L), two
Ni-chrome heating plates (16-L) surrounding a ceramic spacer
(17-L), two composite insulators (18-L), an aluminum oxide heating
plate cover (19-L), electron generator (11), cathode line (21),
carbon fiber brush (22), and circuit checking light (23). One pair
of 110/220 Volt AC power lines (24-L) are connected to the two
Ni-chrome heating plates (16-L). A ceramic spacer (17-L) is
inserted between the two Ni-chrome heating plates (16-L). The two
Ni-chrome heating plates (16-L) are again covered with two
composite insulators (18-L). The composite insulator
(18-L)/Ni-chrome heating plate (16-L)/ceramic spacer
(17-L)/Ni-chrome heating plate (16-L)/composite insulator
(18-L)/assembly is inserted to the groove (25-L) developed on the
aluminum oxide heating plate cover (19-L). The groove (25-L) is
engaged to the other groove (26-L) developed in the upper part of
the plastic housing (14-L) of the lower handle (2-L).
[0014] Another pair of 110/220 Volt AC power lines (25) are
connected to the circuit checking light (23). The light (23) is
attached to the inside of the window (12) developed on one side of
the plastic housing (14).
[0015] The electron generator (11) is connected to an electric
circuit board (27) comprised of capacitance and resistances, which
are embedded in the upper handle (2-U) (is shown in FIG. 4). A
cathode line (21) comes out from the electron generator (20). At
the end of the cathode line (21), a bundle of carbon fiber brush
(22) is connected by a rubber hold (28). The electron generator
(20) is inserted to a holding groove (29) developed on the plastic
handle cover (15-L).
[0016] FIG. 4. is an exploded inside plane view of the upper handle
(2-U) and the upper heating blade (5-U). Another/composite
insulator (18-U)/Ni-chrome heating plate (16-U)/ceramic spacer
(17-U)/Ni-chrome heating plate (16-U)/composite insulator
(18-U)/assembly is inserted to the other groove (25-U) developed on
another aluminum oxide heating plate cover (19-U). The cover (19-U)
and the assembly are inserted on another groove (26-U) developed in
the upper part of the plastic housing (14-U) of the upper handle
(2-U).
[0017] 110/220 Volt electric power source line (30) is connected to
an electric circuit board (27). The two Ni-chrome heating plates
(16-U) are directly connected to the power source lines (30)
without pass through the resistances, transistors and capacitances
on the circuit board (27). One line (30-1) of the power source line
(30) is connected directly to the electron generator (11) and the
other line (30-2) is connected to the circuit board (27) to place
the resistances, transistors and capacitances connects the two
lines (30-1 and 30-2).
[0018] The electric circuit board (27) and lines are embedded in
the lower part of the plastic housing (14-U) of the upper handle
(2-U) and covered with the cover (15-U).
[0019] When the power is supplied to the hair iron (1) of the
present invention by turning on the switch (8) placed on the upper
handle (2-U), the power is supplied directly to the light (23).
Power to the Ni-chrome heating plates (16-L and 16-U) is connected
to the temperature controller (9) placed on the upper handle (2-U)
and supplied to the Ni-chrome heating plates (16-L and 16-U).
[0020] FIG. 5 is the cross sectional view of the inside of the
electron generator (11). The electron generator is comprised of two
electric coils (31-1 and 31-2) from the power lines (30-1 and
30-2). The coils (31-1 and 31-2) are wound around a metal rod (32)
spaced by pluralities of non-conductive spacers (33). On end of the
metal rod (32-e) there is small gap and locates a cathode plate
(34). The cathode plate (34) is connected to the cathode line (21)
and the carbon fiber bundle (22). The whole coils (31-1 and 31-2),
metal rod (32), spacers (33), cathode plate (34), and cathode line
(21) are covered with cement (35) and sealed with a tar layer (36)
to make air free environment.
[0021] When the ac power is supplied to the lines (30-1) and
(30-2), the electric circuit board (27) connected to line 30-2 and
the coils (31-1 and 31-2) form an electron generator (20). Free
electrons (37) are generated from the coils (31-1 and 31-2) and
guided to the cathode (34) by the magnetic field developed by the
coils (31-1 and 31-2) and metal rod (32). The free electrons (37)
pass through the cathode line (21) meets air at the tip of carbon
fiber (22).
[0022] Here, one of the following electrochemical reactions
occurs;
2H.sub.2O+2O.sub.2+4e.sup.-=4OH.sup.-+O.sub.2 (A)
O.sub.2+e.sup.-=O.sub.2.sup.- (B)
[0023] Reaction (A) is more probable in aqueous phase. Reaction (B)
is more probable in air phase.
[0024] The anions produced by any the above reactions (A) and (B)
get out of the straightening iron (1) through the pluralities of
holes (13) and contact with the hair of a user. The most probable
hypothetical reaction is (B) because the atmosphere surrounding the
end of the carbon filter brush (22) is dry. The oxygen anion
(O.sub.2.sup.-) produced by the reaction (B) will be distributed to
the hair of the user through the pluralities of holes (13)
developed along the side part of lower handle (2-L) below the lower
heating blade (5-L). It will react as the source of the anion for
the surfactants reside in the hair of the user after shampooing
(refer to U.S. patents introduced in the PRIOR ARTS about the
shampoos) or will make the environment of the hair more
alkalic.
[0025] The idea of producing anion utilizing ac/dc converter and
applying it to the electric hair treating instruments such as hair
dryers, permanent irons, etc., is easily imaginable.
