Technology field:

The present invention relates to a hair curler, which has a hollow cylindrical part for receiving and winding hair. The hollow body structure of the air inlet for hot air entering the inner space of the hollow flange and the inner space of the cylindrical portion, the hollow flange includes an air outlet facing the cylindrical portion and substantially parallel to the cylindrical portion, the cylindrical portion includes radial air outlet.

Technical background:

In order to form a fixed wave, first shampoo and wind it on a curling iron, and use a known method to first use a wave setting agent and then a neutralizer to obtain long-lasting wave hair.
Then the hair or hair strands are respectively wound from the curling iron, and wound on another curling iron for drying hair, and hot air is delivered to the hair through the curling iron to dry the hair.
This repetitive winding or winding of the hair is a boring, time-consuming operation. In addition, this method requires two sets of curling irons of different configurations.

Improvement measures:

The purpose of this article is to provide a hair curler that adopts a method of delivering hot air from the inner space of the curler to the hair to be dried. At the same time, when its inner space is closed, the curler is suitable for treating hair with hair treatment agents hair curler.
The above-mentioned object is achieved by a hair curler of the present invention, which has a hollow cylindrical part for the hair to be wrapped around. The two ends of the cylindrical part are respectively flanges, and one of the flanges is a hollow body with an air inlet, The inlet will be equipped with a hose for conveying hot air to the inner space of the hollow flange and the inner space of the cylindrical part. The hollow flange includes an air outlet that points to the cylindrical part and is substantially parallel to it. The part includes a radial air outlet on its periphery. It is characterized in that the cylindrical part is a rotary valve structure with a valve body. When in the position, the communication between the inner space and the outside is blocked, and the air outlet of the flange is kept open at both positions of the valve body.

The advantages obtained by the present invention can be fully seen that when the hair is treated with liquid and then dried with hot air, there is no need to repeatedly wrap or wrap the hair.
Therefore, it takes less time to form a permanent wave, and only a set of curling irons are required for post-hair treatment in the whole factory, where the hair is dried by air from the inner space of the curling irons.

A detailed description of the invention will be given below in conjunction with the accompanying drawings describing a specific embodiment.
Fig. 1 is a schematic longitudinal cross-sectional view of the hair curler of the present invention.
Fig. 2 is a side view of the curling iron shown in Fig. 1 partially broken away.

Specific implementation mode:

DETAILED DESCRIPTION: A hair curler generally includes a cylindrical part 1 composed of a hollow body having an inner space 6. One end of the cylindrical part is a flange 2, which is also a hollow body with an inner space 5. The inner space 5 communicates with the inner space 6 via the through hole 14. The opposite end of the cylindrical portion 1 is a flange 3 having a disc-shaped structure.
Therefore, the hair to be treated is wound around the simple part 1 between the hollow flange 2 and the disk flange 3.
The cylindrical part 1 is composed of an outer sleeve 10 and an inner sleeve 9, and the peripheral wall of the outer sleeve 10 contains holes arranged in a certain pattern as the air outlets 8.
The peripheral wall of the inner sleeve 9 also includes holes arranged in a certain pattern as the air passage openings 11. In the example shown in the drawings, the type of the air port 8 is the same as the type of the air port 11. However, it is foreseen that, in particular, the air vent of the inner sleeve 9 can adopt other forms, for example, a single axially extending slit or a plurality of axially extending slits are provided on the peripheral wall of the inner sleeve 9.

The inner sleeve 9 is fixedly connected to the part 12 of the hollow flange 2 to rotate with it. In the embodiment shown in the drawings, the sleeve 9 and the part 12 are integrated. The inner space 5 of the hollow flange 2 is in communication with the inner space 6 of the inner sleeve 9 through at least one through hole 14. As shown in FIG. 1, the portion 12 of the hollow flange 2 includes a radially extending flat-plate-shaped end portion, plus an axially surrounding portion 15. An air inlet 4 is opened in the surrounding portion 15. The air inlet 4 is suitable for connecting a hose to communicate with a hot air source. A device with a hot air source is connected to the hollow hair curler through a hose, so that the hot air flow enters the inner space of the curler and flows out from there through the holes on the peripheral wall of the curler, so as to dry the hair wound on the curler. This is It is generally known, so it won’t be described in further detail.

One end of the outer sleeve 10 with the air passage 11 is a disc-shaped flange 3.
Although the outer sleeve 10 and the disc-shaped flange 3 in FIG. 1 are an integral structure, it is obvious that they may be separate structures fixedly connected together for common rotation. For example, it is also possible that the outer sleeve 10 is made of aluminum, and the flange 3 is made of plastic. This point also applies to the inner sleeve 9 and the hollow flange 2.
At one end of the outer sleeve 10 away from the disc-shaped flange 3, the outer sleeve 10 is connected to the disc 13, and the disc 13 can also be an integral structure with the outer sleeve 10 or a separate structure that is fixedly assembled on the outer sleeve 10 and rotates with it. Parts, this part can also be made of different materials.
The disk 13 constitutes a part of the hollow flange 2. There are notches along the periphery of the disk 13, and these notches along the periphery are covered by the surrounding part 15 to constitute the air outlet of the hollow flange 2 is the axial direction of the sleeves 9, 10.

The inner sleeve 9 is supported to rotate in the outer cylinder 10, whereby the reference number 16 serves as a schematically designed axial guide rail. Therefore, the disc-shaped member 13 of the hollow flange 2 rotates relative to the other parts of the hollow flange 2, such as relative to the parts 12 and 15. In the positions of the sleeves 9 and 10 as shown in the figure, the air port 8 of the outer sleeve 10 and the air port 11 of the inner sleeve 9 are aligned, so the hot air flowing through the air inlet 4 can flow through The hole 14 enters the inner space 6 of the inner sleeve 9 and flows out through the radially aligned through openings 8, 11 to dry the hair wound on the outer sleeve 10.
When the two sleeves 9 and 10 rotate relative to each other, the peripheral wall portion of the inner sleeve 9 without any holes blocks the air passage 8 so that no air flows out of the inner space. It can be seen that in order to open or close the air vent 8, only a small angle is needed. Although the contact point is not explicitly shown, a locking member can be provided, which can respectively lock the two sleeves 9, 10 in the open or closed position and restrict their rotation respectively.
At the same time, it can be seen that with the opening or closing of the air port, the air outlet 7 of the hollow flange 2 is always kept open, so that the axial hot air current used to dry the outer solid area of ​​the wound hair continuously flows out of the air. Give exit 7.
The adjustment of the relative rotation of the sleeves 9, 10 can be made quite simple and convenient. It is only necessary to hold the disc-shaped flange 3 with one hand and the hollow flange 2 with the other hand, especially its surrounding part 15, and then at least one hand’s small movements result in two sleeves 9, 10 rotations.

In order to treat the hair, the hair strands are wrapped around each curler, the sleeve 9, 10 of each curler is first rotated to such a position (this can be done before or after the hair is wound); in this position the air vent 8 is closed. Thereafter, the treatment of styling the hair with waves is carried out in accordance with generally known procedures. The hot air initially blown out axially through the air outlet 7 of the hollow flange 2 slightly heats the hair. After the hair is rinsed, the sleeves 9, 10 are relatively rotated to open the air vent 8 of the outer sleeve 10, so that the hair can pass through the hot air from the air vent 8 and through the air outlet 7 at this time. The hot air dries uniformly from outside.
Therefore, the entire treatment of the hair can be completed with only one curling iron, which greatly saves time in the treatment of the hair.
