Description

Technical Field

[0001] The utility model relates to the field of curling iron technology, and in particular to a novel straightener / curler with essential oil addition function. Background Technology

[0002] A curling iron is a beauty tool used to style hair by curling or straightening it. It changes the shape of the hair through high temperature. With the development of technology and people's increasing demands for hair care, many curling irons on the market can add essential oils when curling hair. By applying essential oils to the hair through the high temperature during curling, it can achieve the effect of curling hair and also have the effect of hair care.

[0003] The technical content disclosed in the Chinese patent document (Publication No.: CN219396528U, Patent Name: Curling Iron with Built-in Hair Oil) is as follows: During the curling process, if hair oil is needed, the user can control the liquid reservoir through a second switch, causing the hair oil in the reservoir to leak out through the oil outlet on the surface of the curling iron body and the heating plate. The hair oil is then used to achieve a smoothing and conditioning effect during the curling process.

[0004] As can be seen from the above implementation plan, the curling iron is equipped with a liquid reservoir to store essential oil. During the curling process, the essential oil can be applied to the hair when the curling iron comes into contact with the hair. However, the application method may result in some hairs having more essential oil applied and some hairs having less essential oil applied, which may lead to a large amount of essential oil being used but not being fully absorbed by the hair. Utility Model Content

[0005] This utility model overcomes the shortcomings of the prior art by incorporating an essential oil container. When the protruding part of the elastic pressing section is pressed, the essential oil flows out and into the essential oil storage tank of the heating rod. When the heating rod heats up, it vaporizes the essential oil in the storage tank. The vaporized essential oil can adhere to the hair. Because the vaporized essential oil particles are small, they can better nourish the hair.

[0033] Compared with existing technologies, the advantages of this utility model are:

[0034] The device features an essential oil container. Once filled with essential oil, the lid is closed, sealing one end of the container while leaving an opening at the other. Due to the small opening and the high surface tension of the essential oil, a water film forms on the surface, preventing it from easily flowing out. Only when the protruding part of the elastic pressing section is pressed, the buffer space is compressed, increasing the air pressure inside the container and breaking the original equilibrium, allowing the essential oil to flow out. The oil flows into the essential oil storage tank of the heating rod. When the heating rod heats up, it vaporizes the essential oil in the storage tank. The vaporized oil adheres to the hair, and because the vaporized oil particles are small, they nourish the hair better. Compared to applying essential oil directly to the hair, this method uses less oil while achieving a better conditioning effect. Attached Figure Description

Detailed Implementation

[0045] The preferred embodiments of the utility model are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the utility model.

[0046] like Figures 1 to 8 As shown, a novel hair straightener / curler with essential oil addition function includes a hair-curling component 4. One end of the hair-curling component 4 is connected to an essential oil component 5. The essential oil component 5 includes an essential oil container 501, and an essential oil cap 502 is provided at one end of the essential oil container 501. When the essential oil cap 502 is connected to the essential oil container 501, it can seal one end of the essential oil container 501. The opening at the end of the essential oil container 501 away from the essential oil cap 502 is small, and the surface tension of the essential oil is high, causing a water film to form on the surface of the essential oil, making it difficult for the essential oil to flow out.

[0047] The essential oil cap 502 includes an inner support portion 5022, which is fitted inside the elastic pressing portion 5021. The inner support portion 5022 has a central hole 50221. The elastic pressing portion 5021 protrudes from the center away from the inner support portion 5022, forming a buffer space 5023 between the elastic pressing portion 5021 and the inner support portion 5022. When the protruding part of the elastic pressing portion 5021 is pressed, the buffer space 5023 is compressed, increasing the air pressure inside the essential oil container 501, breaking the original equilibrium state, causing the water film at the end of the essential oil container 501 away from the essential oil cap 502 to rupture, allowing the essential oil to flow out.

[0048] One end of the essential oil container 501 away from the essential oil cap 502 is connected to the oil guide tube 503, and the other end of the oil guide tube 503 is connected to the oil draining component 504. An oil draining gap 505 is formed between the oil draining component 504 and the upper guide cap 4022.

[0049] After the essential oil flows out, it passes through the oil guide tube 503 and the oil draining component 504, and finally arrives at the upper end of the upper guide cover 4022. Then it flows into the essential oil storage tank 4021 of the heating rod 402. When the heating rod 402 heats up, it vaporizes the essential oil, which is then released through the first vent 4012, thereby nourishing the hair.

[0050] Because the second rod 403 is provided with a second vent 4031 and the curved rod 404 is provided with a third vent 4041, the essential oil can nourish the hair clamped in various parts of the straightener / curler through the second vent 4031 and the third vent 4041, resulting in a better and more complete perming effect.

[0051] Switching component 3 connects to hair perming component 4; switching component 3 includes linkage base 301, within which a switching shaft 304 and a base rotating shaft 305 are disposed, the base rotating shaft 305 being rotatably connected to heating rod linkage seat 302 and clamping drive switch 307; switching shaft 304 is slidably inserted into linkage base 301, heating rod linkage seat 302 and clamping drive switch 307; hair perming component 4 includes a first rod body 401, a second rod body 403 and a curved... Surface rod 404; linkage base 301 connects to the first rod 401, heating rod linkage seat 302 connects to the second rod 403, clamping drive switch 307 connects to the curved rod 404; the cross-sections of the first rod 401 and the second rod 403 are both semi-circular. When the first rod 401 and the second rod 403 are in contact, the plane of the first rod 401 is in contact with the plane of the second rod 403, and the arc surface of the second rod 403 is in contact with the inner arc surface of the curved rod 404. When you need to curl your hair, press the clamping drive switch 307 to drive the curved rod 404 to rotate around the base shaft 305, so that an opening is formed between the curved rod 404 and the second rod 403; then place the hair between the curved rod 404 and the second rod 403, release the clamping drive switch 307, and the curved rod 404 and the second rod 403 will close and clamp the hair inside. The arc surface of the second rod 403 and the inner arc surface of the curved rod 404 together curl the clamped hair.

[0052] Both ends of the switching shaft 304 are equipped with one-button switching buttons 303. When straightening hair is required, pressing the one-button switching button 303 can push the switching shaft 304, which can lock the second rod 403 and the curved rod 404 together. At this time, pressing the clamping drive switch 307 can cause an opening to be formed between the second rod 403 and the first rod 401. Then, the hair is placed in the opening, and the clamping drive switch 307 is released. The plane of the first rod 401 and the plane of the second rod 403 clamp the hair in between. At this time, moving the straightener can straighten the hair.

[0053] Therefore, when switching between the curling and straightening modes using this hair straightener, simply press the one-button switch 303. After the mode switch is completed, pressing the clamping drive switch 307 will open the switch in two different ways: in the curling mode, an opening is formed between the curved rod 404 and the second rod 403, while in the straightening mode, an opening is formed between the second rod 403 and the first rod 401. This will prevent users from making mistakes during use.

[0054] The linkage base 301 is provided with a first linkage switching hole 3011 and a first fixing hole 3012. The first linkage switching hole 3011 includes a communicating first circular hole 30111 and a first elongated hole 30112. The inner diameter of the first elongated hole 30112 is smaller than the inner diameter of the first circular hole 30111. The clamping drive switch 307 is provided with a second linkage switching hole 3071 and a second fixing hole 3073. The second linkage switching hole 3071 includes a communicating second circular hole. 30711 and a second elongated hole 30712, the inner diameter of the second elongated hole 30712 being smaller than the inner diameter of the second round hole 30711; the heating rod linkage seat 302 includes a drive hole 3021 and a rotating shaft hole 3022; the basic rotating shaft 305 is connected to the first fixing hole 3012, the second fixing hole 3073 and the rotating shaft hole 3022; the switching shaft 304 is connected to the first linkage switching hole 3011, the second linkage switching hole 3071 and the drive hole 3021. The first circular hole 30111 of the first linkage switching hole 3011 has a first circular hole 30111 at one end, which is close to the second circular hole 30711 of the second linkage switching hole 3071. The switching shaft 304 includes a central shaft 3044, a middle section 3041 with an outer diameter larger than the central shaft 3044 is provided in the middle of the central shaft 3044, a second linkage post 3043 with an outer diameter larger than the central shaft 3044 is provided at one end of the central shaft 3044, and a second linkage post 3043 with an outer diameter larger than the central shaft 3044 is provided at the other end near the central shaft 3044. The first linkage post 3042; the outer diameter of the middle section 3041 matches the drive hole 3021; ​​the outer diameter of the central shaft 3044 is smaller than the inner diameter of the first long hole 30112, and the outer diameter of the central shaft 3044 is smaller than the inner diameter of the second long hole 30712; the outer diameter of the second linkage post 3043 is larger than the inner diameter of the first long hole 30112 and also larger than the inner diameter of the second long hole 30712, and the outer diameter of the second linkage post 3043 matches the inner diameter of the first round hole 30111 and also matches the inner diameter of the second round hole 30711.

[0055] The linkage base 301 is sandwiched between the lower handle housing 1 and the upper handle housing 2. The clamping drive switch 307 is located on the outside of the upper handle housing 2. The clamping drive switch 307 is also provided with a pressing part 3072. When the operator operates the hair straightener, the palm of the operator holds the handle composed of the lower handle housing 1 and the upper handle housing 2. The thumb can be placed at the pressing part 3072 at any time to press the pressing part 3072. The clamping drive switch 307 is connected to the connecting block 308, and the connecting block 308 is connected to the curved bar 404. A torsion spring 306 is provided between the linkage base 301 and the connecting block 308. Due to the action of the torsion spring 306, the pressing part 3072 is always in a state away from the upper handle housing 2, while the curved bar 404 is always in a state of contact with the second bar 403. Only when the pressing part 3072 is squeezed in the direction closer to the upper handle housing 2 will one end of the curved bar 404 be lifted.

[0056] When the first linkage post 3042 and the second linkage post 3043 are inserted into the first round hole 30111, and the pressing part 3072 is pressed down, when the second long hole 30711 moves, the central shaft 3044 is movably inserted into the second long hole 30711. Therefore, the switching shaft 304 is not pushed. At this time, the second rod 403 is not moved, and the curved rod 404 is separated from the second rod 403.

[0057] When the first linkage post 3042 and the second linkage post 3043 are inserted into the second circular hole 30711, the pressing part 3072 is pressed down. At this time, the central shaft 3044 moves along the first elongated hole 30112. Therefore, the second circular hole 30711 pushes the switching shaft 304. The switching shaft 304 drives the driving hole 3021 of the heating rod linkage seat 302 to rotate around the rotating shaft hole 3022. Therefore, the second rod 403 separates from the first rod 401.
