Description

Comb-type nozzle and hair dryer equipped with this comb-type nozzle

The present invention relates to a comb-shaped nozzle and a hair dryer equipped with the comb-shaped nozzle. More specifically, the comb teeth are formed at the tip of the nozzle so that the user can not only dry the hair by combing with one hand through the hair dryer, but also dry the hair. It relates to a comb-type nozzle for a hair dryer that can improve the drying effect on the hair itself by directing the wind blown between the teeth of the comb to be accommodated between the teeth of the comb rather than escaping to the outside, thus improving the drying effect on the hair itself, and a hair dryer equipped with a comb-type nozzle. .

In general, a hair dryer is a beauty device that dries wet hair or creates your own hairstyle using a comb while drying.

This hair dryer is configured with a heating wire and a fan motor inside the device, so that it can blow warm air by driving the heating wire, or blow air without driving the heating wire.

However, these conventional hair dryers were inconvenient to use because the user held the dryer with one hand and a comb with the other hand, placed the dryer close to the desired area, and combed at the same time.

To solve this problem, a hair dryer equipped with a comb-type nozzle is disclosed in Patent Publication No. 10-2010-0131289 and Publication Patent No. 10-2021-0066347.

A hair dryer equipped with such a comb-type nozzle was convenient to use because it allowed hair to be dried while combing with one hand without having to use a separate comb with a hand other than the hand holding the hair dryer.

In addition, Patent Publication No. 10-2010-0131289 and Publication Patent No. 10-2021-0066347 are configured to dry the hair and scalp by allowing the wind emitted from the hair dryer to be discharged through a comb-shaped nozzle.

However, a hair dryer equipped with a conventional comb-type nozzle may be effective in drying the scalp because the outlet formed in the comb-type nozzle is formed at the end of the comb teeth and the inner end of the space between the comb teeth. Because it could not stay in the space and was pushed out of the comb teeth, it could not be combed properly, and drying the moisture in the hair itself was not effective.

Hereinafter, with reference to FIGS. 1 to 3, a comb-shaped nozzle and a hair dryer equipped with the comb-shaped nozzle according to the first embodiment of the present invention will be described.

The comb-shaped nozzle 100 of the present invention is detachably coupled to the discharge port 201 formed at the tip of the hair dryer body 200 and is used to guide the air discharged from the discharge port 201 toward the hair. At this time, the hair dryer main body 200 is equipped with a fan motor (blower, 210) inside the main body like a normal hair dryer, and is configured to blow air toward the circular discharge port 201, and a heating wire is used to discharge warm air. The heater 220 may be configured to be configured.

The comb-shaped nozzle 100 of the present invention is configured to include a connection portion 110, an air guide portion 120, and a comb tooth portion 130.

The connection part 110 is configured to connect the nozzle 110 to the discharge port 201 by attaching the rear end to the discharge port 201 in a detachable manner, and is usually in the form of a circular tube to correspond to the circular discharge port 201. It consists of

However, of course, the connection part 110 may be fitted into the discharge port 201 in addition to being circular, and may be formed in various shapes corresponding to the shape of the discharge port 201.

The air guide unit 120 is configured to guide the air discharged from the discharge port 201 and introduced into the connection unit 110 into the air chamber 132, which is an internal space of the comb tooth unit 130. The air guide portion 120 is configured to be integrally connected to the connecting portion 110 at the rear end, and is configured to be connected to the comb tooth portion 130 at the front end 121 and is configured to have a rectangular shape with a predetermined length. At this time, the tip 121 of the air guide portion 120 is formed in a rectangular shape with a width smaller than the diameter of the connecting portion 110. That is, the rear end of the air guide portion 120 is circular in the same shape as the connecting portion 110, and the front end is formed in a rectangular shape with a width smaller than the diameter of the connecting portion 110. The air guide portion 120 It is composed of a shape where the width decreases from the rear end to the front end.

In addition, the length of the tip 121 is shown in the drawing as being longer than the diameter of the connecting portion 110, but may be configured to be smaller than the diameter of the connecting portion 110. However, in this embodiment, the length of the tip 121 of the air guide part 120 is configured to be larger than the diameter of the connection part 110, so that the number of comb teeth 131 formed in the comb tooth part 130 can be increased.

The comb teeth 130 consists of a plurality of comb teeth 131 installed in a row at a predetermined interval along the longitudinal direction at the tip of the air guide part 120, and the hair receiving portion is formed at intervals between the comb teeth 131. (134) is formed so that hair can be combed through the comb teeth (131).

Each comb 131 has an air chamber 132 formed inside it, and this air chamber 132 is configured to communicate with the inside of the air guide part 120, so that air flows from the air guide part 120 into the air chamber. It is configured to be supplied to (132).

In the above, the present invention has been described as having an air guide portion 120 formed at the tip of the connecting portion 110 and a comb tooth portion 120 formed at the tip of the air guide portion 120, but it is not limited thereto. The comb teeth 120 are formed directly at the tip of the cylindrical connection part 110 without the configuration of the air guide part 120 so that the internal space of the comb teeth 131, that is, the air chamber 132, is connected to the inside of the connection part 110. It may be configured.

In the present invention, each comb tooth 131 is provided with

side outlets

141 and 142 that communicate with the air chamber 132 inside the comb teeth 131 to discharge and spray the air discharged from the discharge port 201 toward the hair.

In the present invention, as in the past, the outlet is not formed at the end of the comb teeth 131 or the inner end 137 of the hair receiving portion 134, but is located on the opposite side of two adjacent comb teeth 131 in the longitudinal direction. The

side outlets

141 and 142 are configured to penetrate through.

Specifically, the

side outlets

141 and 142 are formed on the first side 135 and the second side 136 of the two neighboring comb teeth 131, respectively, and extend in the longitudinal direction on the first side 135. It includes a plurality of first side discharge vents 141 formed through and spaced apart at predetermined intervals along the second side outlet 136, and a plurality of second side discharge vents 142 formed through penetrating spaces at predetermined intervals along the longitudinal direction. It is configured to do so.

The plurality of first side discharge vents 141 are configured to face the second side 135 and spray air toward the second side 136, and the plurality of second side discharge vents 142 are configured to direct air toward the second side 135. It is configured to face the side 135 and is configured to spray air toward the first side 135.

In this way, the first side discharge vent 141 is configured to spray air toward the second side 136, and the second side discharge vent 142 is configured to spray air toward the first side 135, and the hair receiving groove ( By forming an air flow in the form of an air curtain within the 134), the hair is confined within the hair receiving portion 134 so that it cannot escape to the outside and remains within the hair receiving portion 134, thereby drying the hair within the hair receiving portion 134. Drying efficiency can be improved.

In particular, in the present invention, as shown in FIG. 3, each of the plurality of first side discharge vents 141 and the plurality of second side discharge vents 142 is directed at a predetermined angle toward the inner end 137 of the hair receiving portion 134. It is formed in a shape inclined at θ, and the air injected through the plurality of first side discharge vents 141 and the plurality of second side vents 142 is directed to the inner end of the hair receiving portion 134 at a predetermined angle ( Since the hair is configured to be sprayed at an angle θ, the hair received in the hair receiving groove 134 is pushed toward the inner end 137 of the hair receiving groove 134, thereby drying the hair, so that the hair is discharged from the hair receiving groove 134 to the outside. This further prevents the hair from escaping, and as a result, the hair is dried by the sprayed air while the hair is maintained in the hair receiving groove 134, allowing hair to be dried quickly.

In the present invention, it is preferable that the inclined angle θ of the first side vent 141 and the plurality of second side vents 142 with respect to each

side

135 and 136 is 45 to 90 degrees. If the inclination angle of the first side discharge fan 141 and the plurality of second side discharge vents 142 exceeds 90 degrees, the hair is pushed outward from the hair receiving groove 134 and the hair falls out, and the hair is pulled out at 45 degrees. If it is less than that, the hair may be excessively pushed to the inner end of the hair receiving groove 134, causing hair clumping, which may cause hair performance to be somewhat reduced. Therefore, the first side discharge port 141 and a plurality of second When the inclination angle (θ) of the side outlet 142 is 45 to 90 degrees, good hair drying performance can be achieved without the hair falling out of the hair receiving groove 134.

In addition, as shown in FIG. 3, each of the plurality of first side discharge tuyeres 141 and the plurality of second side discharge tuyeres 142 of the present invention is configured to be disposed at positions offset from each other rather than facing each other.

That is, each of the plurality of first side discharge vents 141 does not face the plurality of second side discharge vents 142 in the lateral direction, that is, the width direction of the hair receiving portion 134, but a plurality of second side discharge vents ( 142) is configured to face the second side 136 on which it is not formed, and similarly, each of the plurality of second side discharge vents 142 has a plurality of second side discharge vents 142 in the lateral direction, that is, in the width direction of the hair receiving portion 134. It is configured not to face the first side vent 141 but to face the second side 135 on which the plurality of first side vents 141 are not formed.

Accordingly, the plurality of first side discharge tuyeres 141 and the plurality of second side discharge vents 142 alternately inject air so that the air injected from the plurality of first side discharge tuyeres 141 is distributed between the plurality of first side discharge tuyeres 141. Since air sprayed from the plurality of second side vents 141 is sprayed to separate the hair contained in the hair receiving portion 134 from each other and the hair is dried, hair drying efficiency can be further improved.

Referring to Figure 4, the comb-shaped nozzle of the present invention is between a plurality of first side discharge tuyeres 141 and a plurality of second side discharge tuyeres 142 on the two opposing

sides

135 and 136 of the two neighboring comb teeth 131, respectively. ) may be configured so that hair separation spray holes 151 and 152 are additionally formed between them.

Specifically, a first hair separation spray hole 151 communicating with the air chamber 142 is formed between the first side discharge ports 141 on the first side 135, and a first hair separation injection hole 151 is formed through the second side 136. A second hair separation injection hole 152 communicating with the air chamber 142 is formed penetrating between the two side discharge vents 142.

These hair separation spray holes (151, 152) are configured to have a diameter of at least 1/2 or less than the diameter of the side outlets (141, 142), and between each outlet (141, 142), the air is smaller than the air sprayed through the outlets (141, 142). The drying performance of the hair can be improved by spraying the hair with fine-sized air.

Referring to FIGS. 5 to 7, the distal end of the comb teeth 131 of the present invention is operated to protrude into the hair receiving portion 134 by the pressure of the air supplied to the air chamber 132, thereby causing the hair receiving portion 134 to protrude. A shutter means 160 that blocks the outer end portion to prevent hair from falling out may be additionally configured.

Each shutter means 160 is rotatably installed in the shutter seating groove 138 formed at the side end of the comb 131 by a hinge portion 162, and is inserted into and seated in the shutter seating groove 138 or is installed in the shutter seating groove 138. A hair blocking plate 161 configured to rotate so as to protrude into the inside of the hair receiving portion 134 at (138), and an air chamber ( 132) An air operating plate 164 that is configured to protrude inward and rotates by the air pressure of the air flowing into the air chamber 132 to rotate the hair blocking plate 161 so that it protrudes into the inside of the hair receiving portion 134. And, it is configured to include an elastic member 166 made of a torsion spring installed on the hinge portion 162 and providing elastic force so that the hair blocking plate 161 returns to the shutter seating groove 138.

When the hair dryer body 120 is driven and air is supplied to the air chamber 132 inside the comb teeth 131, the shutter means 160 operates on the air operating plate by the pressure of the air supplied into the air chamber 132. As (164) rotates, the hair blocking plate 161 rotates to protrude toward the outer side of the hair receiving portion 134, so that the hair accommodated in the hair receiving portion 134 is exposed to the outside through the outer portion of the hair receiving portion 134. It blocks it from falling into.

At this time, the shutter means 160 installed at the distal ends of the two opposing

sides

135 and 136 of the two neighboring comb teeth 131 has each hair blocking plate 161 centered at the width direction of the hair receiving portion 134. The two hair blocking plates 161 are rotated toward each other as shown in FIG. 7 to block the outer portion of the hair receiving portion 134 to prevent the hair accommodated in the hair receiving portion 134 from falling out.

In the present invention, the length of the hair blocking plate 161 is configured to be longer than 1/2 of the width interval of the hair receiving portion 134, so that the hair blocking plates 161 on both sides are rotated at a right angle to the side of the comb teeth 131. Before the hair blocking plate 161 on both sides touches each other, the ends of the hair blocking plates 161 are configured to complete the blocking operation.

Although the present invention has been shown and described in connection with preferred embodiments for illustrating the principles of the present invention, the present invention is not limited to the configuration and operation as shown and described. Rather, those skilled in the art will be able to understand that many changes and modifications can be made to the present invention without departing from the spirit and scope of the appended claims. Accordingly, all such appropriate changes, modifications and equivalents shall be considered to fall within the scope of the present invention.

The present invention as described above can be widely used in fields related to hair dryers and dryer accessories.
