The present invention relates to a hair brush for hot curling, and in particular, to form a cross-section of the body constituting the hair brush in a substantially square with rounded corners to shorten hair drying time and improve curling efficiency, and to fix the brush hair By forming a non-slip on the outer surface to promote the life of the product by the firm fixation of the brush bristle, by forming a round on the end of the bristle to prevent scalp damage and smooth combing is possible.

In general, the hot curling hair brush is used to form a wave in the form desired by the user at the same time to dry the wet hair quickly using a hair dryer.

In addition, the general hot curling hair brush is a handle of the appropriate length and shape, the body of the aluminum tube is fixed to the upper portion of the handle and a plurality of through-holes are formed at regular intervals on the outer surface, the stopper is press-fit fixed to the top of the body And a mandrel installed between the handle and the stopper so as to be located at the inner center of the body, and having a mandrel composed of two twisted iron cores, and a brush bristle fixed to a radial spiral between the mandrel and exposed to the outside of the through hole of the body. have.

In the conventional hot curling hair brush having such a configuration, the hot air of the hair dryer is sprayed in a state in which the hair is wound around the body during use. In this case, the hot air enters the gap of the hair which is opened at a predetermined interval by the brush hair, thereby opening the through hole. Since the body is raised to a certain temperature while being introduced into and discharged through the body, the wet hair is dried in a short time and at the same time, a wave is formed in a form desired by the user.

However, the problem that the thermal efficiency is not high in the conventional hot curling hair brush has been pointed out.

That is, when drying or curling the hair, the user holds the hair brush with one hand, and with the other hand, the hot air discharge port of the hair dryer is close to the body of the hair brush to inject the warm air, wherein the body has a circular cross section. Therefore, only the area close to the hot air outlet is intensively heatd, so it takes a lot of time to dry the hair and causes a problem that a lot of time is required even when curling to form a wave. Due to structural problems.

In addition, in the conventional hair brush has been pointed out that the problem that the life of the product is shortened because the brush hair can be easily taken out.

In other words, the bristles are configured to arrange the bristles cut to a certain length between the two cores constituting the core rod at the time of manufacture, and to fix the bristles between both cores by twisting the iron cores. Since the hot air of about 170 ° C. discharged directly heats the brush hair, the brush hair having a softening point of about 180 ° C. is easily separated from the mandrel even if a small tensile force is applied from the outside to shorten the life of the product.

Another problem with the conventional hair brush is that the tip of the brush hair is sharp, causing scalp damage when used.

It is used to cut the long bristle material to be cut to a certain length, the cutting surface of such a bristle has a sharp cross-section that is likely to damage the scalp during use and the feeling of combing is very rough, so users who require soft combing It will provide a key factor in lowering product preference.

In view of the above problems, an object of the present invention is to provide a hair brush for hot curling which can minimize power consumption and maximize thermal efficiency by shortening drying time and improving curling efficiency.

Another object of the present invention is to provide a hair brush for hot curling that can significantly extend the life of the product by fixing the brush hair more firmly.

Still another object of the present invention is to provide a hair curler for hot curling that can give a soft feeling of use without fear of scalp damage during use.

In order to effectively achieve the above object, in the present invention, the body constituting the hair brush is formed in a substantially rectangular cylindrical shape with rounded corners to minimize drying time and maximize curling efficiency, and to prevent slipping on the outer surface of the iron core constituting the core rod. By increasing the frictional force to maintain the firm fixation state of the brush head for a long time, and to prolong the life of the product, and to form the round head part by polishing at the tip of the brush head to eliminate the risk of scalp damage and to feel the user's product smoothly. The preferences can be greatly improved.

Hereinafter, preferred embodiments of the present invention will be described in detail by the accompanying drawings.

1 is a perspective view of a hairbrush B to which the present invention is applied, and in FIG.

Hair brush (B) of the present invention is a fixed length and shape of the handle 1, the connection portion 11 is formed, and fixed to the connecting portion 11 of the handle 1, a plurality of through holes 21 on the outer surface Body 2 of the aluminum tube formed at regular intervals, the stopper (3) is press-fit fixed to the upper end of the body (2), the handle (1) and the stopper (3) to be located in the inner center of the body (2) Brush heads of suitable length that are fixedly installed between the core rods 4 composed of two twisted iron cores and radially pressurized radially between the iron cores constituting the core rods 4 and exposed to the outside of the through hole 21. The configuration of (5) is the same as in the prior art.

As shown in FIG. 3, the first feature of the present invention is a portion in which the body 2 is formed in a substantially rectangular cylinder having rounded corners, and the quadrangular surfaces are formed in an arc-type flat portion 22. The corner of the square was composed of a round part 23.

In such a configuration, the hair is wound around the body 2 when the hair brush B is used, and the hot air of the hair dryer is sprayed close to the body 2 to advance the hair drying and curling.

Figure 4 shows a cross-sectional configuration of the conventional body (2a) in a circular configuration for comparison with the body (2) according to the present invention, when the hair dryer close to the conventional body (2a), Only the part where the hot air outlet is close is heated intensively, and the farther it is from the hot air outlet, the temperature is drastically lowered. Therefore, considerable time is required for drying or curling the desired hair, thus causing problems such as increased power consumption and time lag. do.

However, when the user closes the hot air outlet of the hair dryer to the flat portion 22 in a state in which the wet hair is wound around the body 2a as in the present invention, the hot air is spread widely to maximize the drying efficiency. At this time, some of the hot air flows in the body 2 through the through-hole 21 and conducts heat, so that the drying efficiency is further improved.

In addition, when the hot air outlet of the hair dryer is close to the corner portion of the body 2, that is, the round portion 23, in this case, only the round portion 23 is intensively heated, so that the curling effect is further improved. It is possible to form a wave of a desired shape in a short time.

As shown in FIG. 5, the second feature of the present invention is a portion in which an anti-slip part 42 is formed on the outer surface of the iron core 41 constituting the core rod 4.

The mandrel 4 is arranged by arranging the bristles 5 in a row between two iron cores 41 cut to the appropriate length at the time of manufacture, and twisting both ends of the iron core 41 in different directions. ) Is fixed in a radial spiral between both iron cores 41.

In particular, in the present invention, since the anti-slip portion 61 is formed on the outer surface of the iron core 41, the brush bristle 5 is more firmly fixed.

That is, since the bristles 5 are made of synthetic resin, the bristles are slightly pressed between the iron cores 41 by their own elasticity. Therefore, it is separated from the iron core 6 by a small external tensile force.

However, when the non-slip portion 42 is formed in the iron core 41 as in the present invention, the bristle 5 is slightly compressed by the pressing force of both iron cores 41, wherein the outer surface of the bristle 5 A part is pressed into the non-slip portion 42 is more firmly fixed by the increase in frictional force to retain excellent tensile strength compared to the prior art.

The non-slip portion 42 is shown as having formed the micro grooves in the horizontal direction on the outer surface of the iron core 41, which can be configured very easily by a knurling tool, etc. Of course, they can also be configured in a vertical direction, an oblique direction, a lattice, or the like, and in this case, the same effect can be obtained.

As shown in FIG. 6, the third feature of the present invention is a portion in which the end of the brush brim 5 is rounded, and the round head portion 51 is polished by grinding the end of the bristle 5 cut to a predetermined length. Was formed.

7A and 7B illustrate the configuration of the conventional brush hairs 5a and 5b, and by partially heating the ends of the brush hairs 5a as shown in FIG. 7A in order to prevent scalp damage and soft feeling of combing, The water droplets are cooled by the contraction force and the surface tension of the material itself, and then cooled to form a water droplet head 52 at the end of the brush brim 5a, or the end of the brush brim 5b as shown in FIG. The epoxy resin was solidified in the container filled with the epoxy resin liquid to solidify at the end of the brush brim 5b to form the epoxy head portion 53.

However, in the former case, the strict manufacturing process management such as the temperature, the access interval, and the time of the heat source for melting the brush brim 5a is required, and the standard of the finished head part 52 is not uniform. This is caused.

In the latter case, a separate epoxy resin is required, a considerable time is required for curing the epoxy resin, and the epoxy hub portion 53 is easily separated from the brush brim 5b due to repeated vibration shock and temperature difference during use. The problem is that the life of the product is shortened.

On the contrary, since the bristles 5 according to the present invention are formed at the end of the round head 51 by grinding, the risk of scalp damage due to the sharp cutting surface is fundamentally eliminated, and since the comb is gently combed when used, the user's product preference To increase.

As described above, the present invention hot curling hair brush (B), by forming a square with rounded corners of the body (2) can quickly dry and curl the hair as needed, so drying and curling efficiency By minimizing power consumption and maximizing thermal efficiency, the non-slip portion 42 is formed on the outer surface of the iron core 41 constituting the core rod 4, and the brush brim 5, which is pressed and fixed therebetween, is further formed. By firmly fixing, it is possible to proactively solve the life shortening factor of the product due to the escape of the brush bristle (5) and to extend the life, and the round head portion 51 by grinding is formed at the end of the bristle (5) Smooth combing without irritating and damaging the scalp has a wide range of effects such as greatly improving the user's product reliability and preferences.
