Description

Nozzle device for hair dryer

The present invention relates to a nozzle device for a hair dryer, and more particularly, to a nozzle device for a hair dryer capable of preventing hair from fluttering or tangling during drying and suppressing hair damage.

In general, a hair dryer blows hot air into the hair to dry the hair or to change the shape of the hair. A blower for blowing air and a heater for heating the air are installed in the hair dryer. The discharge part of the hair dryer is formed in the shape of a long hole so as to spray air in a straight line to the hair.

However, in the conventional hair dryer, hair is blown by the discharge pressure of air, so some of the sprayed air may not be used to dry the hair.

In addition, since the hair is blown by the air, as the hair below the clavicle dries later, the amount of time the hair in the corresponding area is exposed to the hot air directly sprayed from the outlet of the hair dryer may be increased. Therefore, hair damage in the area below the clavicle can be promoted.

In addition, when using a hair dryer to dry hair, the ends of the hair are mainly damaged due to direct contact between the hair and the high-temperature air sprayed from the hair dryer. There was a problem that the skin of the face was directly exposed to the high-temperature exhaust air because it relied on the air of the body, causing skin damage.

In addition, in order to prevent the hair from being curled or fluttered, it is inconvenient to hold the hair with one hand and dry the hair.

The background technology of the present invention is disclosed in Korean Patent Application Laid-Open No. 2010-006711 (published on Jul. 01, 2010, title of the invention: a hair dryer emitting bio far-infrared rays).

SUMMARY OF THE INVENTION It is an object of the present invention to provide a nozzle device for a hair dryer capable of preventing hair from fluttering or tangling when drying hair, and suppressing damage to hair as well as damage to facial skin.

A nozzle device for a hair dryer according to the present invention includes: a connector unit coupled to the hair dryer and having an air inlet formed thereon; and hair extending from the connector part to both sides to form a hair inlet part and a hair receiving part, a flow channel part communicating with the air inlet part is formed, and an air injection part is formed to spray air to the hair accommodated in the hair receiving part. It is characterized in that it includes a holder part.

The air spraying unit may include a plurality of air spraying holes formed on the inner surface of the hair holder.

The plurality of air injection holes may be formed to spray air toward the center of the hair holder.

The plurality of air injection hole portions may be formed to be biased toward the hair lead-in portion to prevent hair from coming out through the hair lead-in portion.

The plurality of air injection hole portions may be formed to have different sizes.

The air injection hole portion disposed at the closest distance to the hair inlet portion may be formed to be the largest.

An auxiliary injection hole portion may be formed on the connector portion side of the hair holder portion to spray air toward the center portion of the hair holder portion.

The hair holder part may be formed so that both sides thereof are symmetrical to each other based on the connector part.

The hair holder part may have the same curvature of the connector part as the curvature of the hair lead-in part.

The hair holder part may be formed to have a different curvature from the side of the connector part and the curvature from the side of the hair lead part.

The hair holder part may be formed so that a curvature of the connector part is smaller than a curvature of the hair lead-in part.

Both sides of the hair holder part may be asymmetrically formed with respect to the connector part.

The hair holder part may be formed to have different lengths on both sides based on the connector part.

The hair holder part may further include a branch guide part formed in the hair holder part to branch the air introduced through the air inlet part to both sides of the flow channel part.

The hair holder part may further include a direction change guide part which is formed on a side of the hair inlet part of the flow channel part and converts air toward the center part of the hair receiving part.

The connector unit includes a coupling unit to which the air discharge unit of the hair dryer is coupled; and a tapered portion extending from the coupling portion.

A hook portion may be formed in the coupling portion to constrain the air discharge portion of the hair dryer.

The hair holder unit may further include an anti-tangling unit that is formed to protrude inwardly of the hair holder unit to prevent the hair from being tangled.

The tangle preventing unit may include one or more tangle preventing ribs formed on the inner surface of the hair holder unit.

The tangling rib may be formed in a plate shape parallel to the width direction of the hair holder part.

The anti-tangle rib may be formed to be thinner toward the center of the hair holder.

The tangle preventing portion includes a coupler unit detachably coupled to the inner surface of the hair holder portion; and an anti-tangle rib formed to protrude from the coupler part to the inside of the hair holder part.

As described above, according to the present invention, since the air is sprayed onto the hair while the hair is surrounded by the hair holder, it is possible to prevent the hair from freely fluttering or tangling by the spraying pressure of the air. In addition, since most of the air sprayed through the air spraying unit can be used for drying the hair, it is possible to minimize hair damage by shortening the drying time of the hair.

In addition, the present invention is provided with a flow channel portion in which the high-temperature air introduced from the hair dryer circulates and moves in the longitudinal direction of the hair holder portion to prevent the high-temperature air generated from the hair dryer from directly contacting the hair or facial skin, It has the effect of preventing damage to the skin of the face as well as hair damage by maintaining a constant temperature and allowing it to circulate.

In addition, according to the present invention, a plurality of air injection hole portions are formed to spray air toward the central portion of the hair holder. Accordingly, since the hair is dried while being moved toward the center by the spraying pressure of air, it is possible to prevent the hair from leaving the hair holder, thereby improving the drying performance of the hair.

Further, according to the present invention, since the anti-tangling portion is formed to protrude to the inside of the hair holder portion, the anti-tangling portion can be positioned between the hairs when the hair is accommodated in the hair receiving portion. Therefore, since the tangling unit separates the hair of the hair receiving unit into a plurality of groups, it is possible to prevent the hair from tangling with each other and to improve the drying performance of the hair.

Therefore, definitions of these terms should be made based on the content throughout this specification.

It is a drawing.

1 to 4 , the nozzle device 100 for a hair dryer according to the first embodiment of the present invention includes a connector unit 110 and a hair holder unit 120 .

The connector unit 110 is coupled to an air discharge unit (not shown) of a hair dryer (not shown). The connector unit 110 is formed in the same shape as the air discharge unit so that the air discharge unit is fitted. For example, when the air outlet of the hair dryer has a circular or oval shape, the connector part 110 may be formed in a circular or oval shape. In addition, when the discharge part of the hair dryer has a polygonal shape, the connector part 110 may be formed in a polygonal shape.

The connector part 110 includes a coupling part 111 coupled to the air discharge part of the hair dryer, and a tapered part 112 extending from the coupling part 111 . The coupling part 111 is connected to the center of the hair holder part 120 . The coupling part 111 is formed in a ring shape so that the air discharge part of the hair dryer is fitted. The tapered part 112 is formed in a shape in which the diameter decreases from the connector part 110 to the hair holder part 120 side. Since the air discharged from the air discharge unit flows while being collected toward the hair holder unit 120 by the tapered unit 112 , the flow rate and flow pressure of the air supplied to the hair holder unit 120 may be increased. Accordingly, since the flow rate and flow rate of the air discharged to the inside of the hair holder unit 120 can be increased, it is possible to shorten the drying time of the hair, thereby minimizing damage to the hair.

A hook part 113 is formed on the inner surface of the connector part 110 to restrain the air discharge part of the hair dryer. A plurality of hook parts 113 are formed along the circumference of the connector part 110 . The hook part 113 includes an elastic part 114 and a locking protrusion 115 . The elastic portion 114 includes an elastic piece 114a integrally formed with the coupling portion 111 and slit portions 114b formed on both sides of the elastic piece 114a. When the air discharge unit of the hair dryer is fitted into the coupling portion 111 of the connector unit 110 , the air discharge unit is constrained to the connector unit 110 by the restoring force of the elastic piece 114a. In addition, the locking protrusion 115 constrains the air discharge unit so that the air discharge unit does not fall out from the connector unit 110 .

A limiting protrusion 117 is formed on the inner surface of the connector 110 to limit the insertion depth of the air outlet of the hair dryer. When the air outlet of the hair dryer is inserted into the connector 110 , the end 131 of the air outlet is caught by the limiting protrusion 117 to limit the insertion depth of the air outlet. In addition, since the limiting protrusion 117 supports the end of the air discharge unit, it is possible to prevent the air discharge unit and the connector unit 110 from having a gap due to the flow pressure or external force of the air.

The hair holder part 120 extends from the connector part 110 to both sides so that the hair inlet part 121 and the hair receiving part 122 are formed. A flow channel part 123 communicating with the air inlet 111a is formed in the hair holder 120 , and an air spraying part 124 is formed to spray air to the hair accommodated in the hair receiving part 122 . The hair holder unit 120 may be formed in a “C” or “U” shape that surrounds the hair and has one side open. A hair lead-in part 121 is formed in a portion of the hair holder part 120 opposite to the connector part 110 . The hair receiving unit 122 is a space surrounded by the hair holder unit 120 . The flow channel part 123 is formed to be elongated in the longitudinal direction of the hair holder part 120 .

Since the hair is drawn into the hair receiving unit 122 through the hair receiving unit 121 , a certain amount of hair may be accommodated in the hair receiving unit 122 as the hair holder 120 moves toward the hair. In addition, since air is sprayed onto the hair while the hair is surrounded by the hair holder unit 120 , it is possible to prevent the hair from freely fluttering or tangled by the spraying pressure of the air. In addition, since most of the air injected through the air jetting unit 124 can be used for drying the hair, damage to the hair can be minimized by shortening the drying time of the hair.

In addition, since the hair holder unit 120 can be moved in the longitudinal direction of the hair while surrounding the hair, the hair can be dried quickly as a whole. In addition, when the hair is dried in a state where the hair holder unit 120 is positioned below the clavicle of the hair, it is possible to prevent the part of the hair below the clavicle from leaving the hair holder unit 120 and fluttering. Accordingly, as the drying time of the lower part of the hair is shortened, damage to the tip of the hair can be minimized.

The air injection unit 124 includes a plurality of air injection hole portions 124a formed on the inner surface of the hair holder unit 120 . As the air injected through the plurality of air injection holes 124a is concentrated on the hair, it is possible to shorten the drying time of the hair.

The air injection hole 124a may be formed parallel to the width direction (height direction) of the hair holder unit 120 . In this case, the air injection hole portion 124a may be formed in a straight shape. Accordingly, since the air injection hole 124a sprays air in parallel with the lengthwise direction of the hair, as the hair strands are more spaced apart, the drying performance of the hair can be further improved.

The plurality of air injection holes 124a are formed to spray air toward the center of the hair holder 120 . Therefore, since the hair is dried while being moved toward the center by the spraying pressure of air, it is possible to prevent the hair from leaving the hair holder unit 120 , thereby improving the drying performance of the hair.

The plurality of air injection hole parts 124a are formed to be biased toward the hair lead-in part 121 to prevent hair from coming out through the hair lead-in part 121 . Since the plurality of air injection hole portions 124a are formed to be biased toward the hair inlet 121 side, the air injected through the air injection hole portion 124a flows toward the connector part 110 to dry the hair. Accordingly, it is possible to further prevent the hair from leaving the hair holder unit 120 .

The plurality of air injection hole portions 124a may be formed to have different sizes. For example, the odd-numbered air injection hole 124a in the hair lead-in part 121 may have a large size, and the even-numbered air injection hole 124a may have a relatively small size. In addition, the size of the air injection hole 124a may be gradually reduced as the distance from the hair lead-in part 121 is increased. Therefore, it is possible to adjust the amount of air injection for each position of the air injection hole 124a.

The air injection hole 124a disposed at the closest distance from the hair inlet 121 may be formed to be the largest. At this time, the size of the air injection hole portion 124a except for the air injection hole portion 124a disposed at the closest distance to the hair inlet portion is the same, or the size of the air injection hole portion 124a increases as the distance from the hair intake portion 121 increases. can be reduced. When the air injection hole 124a disposed at the closest distance from the hair lead-in part 121 is formed to be the largest, the air injection pressure at the side of the hair lead-in part 121 may be formed to be the largest. Accordingly, since the hair is dried while moving away from the hair lead-in part 121 , it is possible to prevent the hair from coming out through the hair lead-in part 121 .

On the connector part 110 side of the hair holder part 120 , an auxiliary injection hole part 125 is formed to inject air into the hair holder part 120 . The size of the auxiliary injection hole 125 may be relatively reduced compared to the size of the air injection hole 124a. Therefore, even if the air injected from the air injection hole 124a moves the hair unbalanced toward the connector 110, as the air injected from the auxiliary injection hole 125 is applied to the hair, the hair is held in the hair holder unit ( 120) can be spaced apart from the inner surface. Furthermore, it is possible to further improve the drying performance of the hair and shorten the drying time of the hair.

The hair holder unit 120 further includes a branch guide unit 130 formed in the hair holder unit 120 to branch the air introduced through the air inlet unit 111a to both sides of the flow channel unit 123 . . The branch guide part 130 is formed in the center of the hair holder part 120 to correspond to the air inlet part 111a of the connector part 110 . The end 131 of the branch guide part 130 is formed to be round, and the side part 132 of the branch guide part 130 is formed in a shape that spreads from the end 131 . The side part 132 is concave toward the center of the branch guide part 130 . Since the branch guide 130 branches the air introduced through the air inlet 111a to both sides of the flow channel 123 , the air in the air inlet 111a branches to both sides of the flow channel 123 . It is possible to minimize the flow resistance of air when

It is formed on the hair inlet portion 121 side of the flow channel portion 123, and further includes a direction change guide portion 140 for converting the air toward the center of the hair receiving portion (122). The direction change guide unit 140 may be formed parallel to the radial direction of the hair holder unit 120 . Since the direction change guide unit 140 changes the flow direction of air from the hair lead-in unit 121 to the central portion of the hair receiving unit 122 , the hair of the hair receiving unit 122 moves to the center of the hair receiving unit 122 . It can be dried while moving to the side.

[Table 1] below shows the results of testing the temperature of the air introduced from the hair dryer and the temperature of the air injected into the hair through the air spraying unit when the nozzle device for a hair dryer according to an embodiment of the present invention is used. . In the following test, when the temperature of the air introduced from the hair dryer is 50 degrees Celsius, 60 degrees, 70 degrees, 80 degrees, 90 degrees, 100 degrees, and 110 degrees, respectively, the wind strength was measured for 20 minutes in the highest state, All conditions except the temperature of the incoming air were maintained the same.

Referring to [Table 1] above, when the nozzle device for a hair dryer according to an embodiment of the present invention is used, the temperature of the air sprayed to the hair is kept constant at a relatively low temperature compared to the air introduced from the hair dryer. Therefore, according to the present invention, it can be seen that the high-temperature air flowing in from the hair dryer in the longitudinal direction of the hair holder part circulates to prevent damage to the hair by lowering the temperature and maintaining it constant.

5 to 8 , the hair holder unit 120 further includes an anti-tangling unit 150 that is formed to protrude inward of the hair holder unit 120 to prevent the hair from being tangled. Since the tangle preventing unit 150 is formed to protrude inward of the hair holder unit 120 , the tangle preventing unit 150 may be positioned between the hairs when the hair is accommodated in the hair receiving unit 122 . Accordingly, since the tangle preventing unit 150 separates the hair of the hair receiving unit 122 into a plurality of groups, it is possible to prevent the hair from tangling with each other and to improve the drying performance of the hair.

The tangle preventing unit 150 includes one or more tangle preventing ribs 153 formed on the inner surface of the hair holder unit 120 . For example, one anti-tangle rib 153 may be formed in a portion of the hair holder 120 where the branch guide 130 is formed (see FIGS. 5 and 6 ). In addition, two anti-tangle ribs 153 may be formed on both sides of the portion where the branch guide is formed in the hair holder 120 (see FIGS. 7 and 8 ). The number of tangle-preventing ribs 153 installed may be appropriately changed in consideration of the size of the hair holder unit 120 and the shape of the hair (straight or permed hair).

The anti-tangle rib 153 is formed in a plate shape parallel to the width direction of the hair holder unit 120 . Accordingly, the hair holder unit 120 moves smoothly along the length of the hair, and damage to the hair due to the friction of the hair holder unit 120 can be minimized.

The anti-tangle rib 153 is formed to have a thinner thickness toward the center of the hair holder 120 . Accordingly, the tangling rib 153 can smoothly enter between the hairs.

Referring to FIG. 9 , the tangle preventing unit 150 may be detachably installed on the inner surface of the hair holder unit 120 . For example, the coupler part 151 detachably coupled to the inner surface of the hair holder part 120, and the tangling prevention rib 153 formed to protrude from the coupler part 151 to the inside of the hair holder part 120 ) is included. The coupler unit 151 is formed to be round in a form in close contact with the inner surface of the hair holder unit 120 . Coupling protrusions 152 are formed on both sides of the coupler unit 151 to fit into the hair holder unit 120 . One or more anti-tangle ribs 153 may be formed in the coupler unit 151 . Since the tangle preventing unit 150 is detachably installed on the hair holder unit 120 , the tangle preventing unit 150 may be coupled to or separated from the hair holder unit 120 according to a user's preference.

Referring to FIG. 10 , both sides of the hair holder unit 120 may be symmetrically formed with respect to the connector unit 110 . In this case, the hair lead-in part 121 is disposed to face the front of the connector part 110 . Accordingly, since air is uniformly sprayed from both sides of the hair holder unit 120 , the hair can be dried while moving toward the center of the hair holder unit 120 .

The hair holder part 120 may have the same curvature R1 on the connector part 110 side and the curvature R1 on the hair lead part 121 side (R1=R2). Accordingly, the left and right sides of the hair holder unit 120 may be formed in an arc shape, respectively.

Referring to FIG. 11 , the hair holder part 120 may have a different curvature R1 on the connector part 110 side and a different curvature R2 on the hair lead part 121 side. For example, in the hair holder part 120 , the curvature R1 of the connector part 110 side is smaller than the curvature R2 of the hair lead part 121 side (R1<R2). In this case, since the space on the connector part 110 side of the hair holder part 120 is relatively wider than the space on the hair lead part 121 side, the hair moves from the hair receiving part 122 to the connector part 110 side. It can be dried in a tilted state.

Referring to FIG. 12 , both sides of the hair holder unit 120 may be asymmetrically formed with respect to the connector unit 110 . For example, one side of the hair holder unit 120 may be formed in an arc shape with respect to the connector unit 110 , and the other side of the hair holder unit 120 may not be formed in an arc shape. Also, the curvature of one side of the hair holder unit 120 and the curvature of the other side of the hair holder unit 120 may be different from each other.

The hair holder unit 120 may be formed to have different lengths on both sides with respect to the connector unit 110 (L1<L2). For example, the length L1 of the part of the hair holder 120 positioned on the user's head side may be shorter than the length L2 of the part of the hair holder part 120 positioned on the opposite side of the head. In this case, since the hair lead-in portion 121 is formed at a slightly biased position from the front of the connector to one side, the hair is smoothly drawn into the hair holder portion 120 when the hair holder portion 120 is moved to the hair side. can be

As described above, in the present invention, since air is sprayed onto the hair while the hair is surrounded by the hair holder, it is possible to prevent the hair from freely fluttering or tangling due to the spraying pressure of the air. In addition, since most of the air injected through the air spraying unit can be used for drying the hair, damage to the hair can be minimized by shortening the drying time of the hair.

Although the present invention has been described with reference to the embodiment shown in the drawings, this is merely an example, and those skilled in the art to which various modifications and equivalent other embodiments are possible. will understand
