Description

Technical Field

[0001] The present invention relates to the field of hair curlers, and particularly to a hair curler having a steam generation structure.

Background Art

[0002] Steam curling technology is an important part of the hair styling tool field. Its core principle is to gently process the hair using the humid heat effect of steam to achieve long-lasting natural styling. Compared with conventional hot hair curlers, steam hair curlers can penetrate water molecules into the interior of the hair shaft, moderately soften the hair cuticle, and thus achieve better curl and elasticity maintenance at a lower temperature while reducing the generation of static electricity and improving the gloss and smoothness of the hair. As consumers' needs for hair care are increasing, steam hair curlers are gradually penetrating from professional salons into the household appliance market and are being used as an important tool for daily styling and care.

[0003] In the process of actually using conventional steam hair curlers, some products use a steam generation method of dripping liquid onto a high-temperature metal surface or a small built-in boiling chamber. When water comes into non-uniform contact with the high-temperature wall surface, the generation of steam is unstable, resulting in interrupted steam injection, scattering of water droplets, or abnormal noises, which affects the stability of steam delivery. Due to local overheating or insufficient wetting, there is a risk of damaging the hair quality. Also, if the steam is not sufficiently buffered or distributed during transportation, the airflow is likely to concentrate, making it difficult to uniformly penetrate each layer of the hair, reducing the utilization efficiency of the steam, and compromising the styling effect.

[0004] Therefore, it is necessary to provide a hair curler having a steam generation structure to solve the above problems.

Mode for Carrying Out the Invention

[0020] The following further describes the present invention using examples.

[0021] As shown in Figures 1 to 7, the present invention is a steam generation structure including: a steam cylinder 1; a steam chamber 2 provided inside the steam cylinder 1; a water supply bracket 3 provided inside the steam cylinder 1 and located on one side of the steam chamber 2; a connecting mechanism 4 connected to the water supply bracket 3; absorbent cotton 5 fixed on the water supply bracket 3, with one side in contact with the internal water guide groove of the water supply bracket 3 and the other side in close contact with the inner wall of the steam chamber 2; at least one set of PTC heating assemblies 6 provided inside the steam cylinder 1 and in thermal contact with the wall surface of the steam chamber 2; an exhaust hole 7 opened on the wall surface of the steam chamber 2; a steam storage chamber 8 provided on the steam cylinder 1 and in fluid communication with the exhaust hole 7; and a gas venting component 9 provided on the steam storage chamber 8 and having a gas venting hole 10. The hair curler is provided, and the water tank is located behind the center of the handle section 13. A small water pump built into the handle section 13 supplies liquid water to the internal water guide groove of the water supply bracket 3 via a connecting mechanism 4. The absorbent cotton 5 fixed on the water supply bracket 3 utilizes capillary action to continuously and uniformly absorb moisture from the water guide groove on one side, while the other side of the absorbent cotton 5 is in close contact with the inner wall of the steam chamber 2. The heat generated during the operation of the PTC heating assembly 6 is directly transferred to the wall of the steam chamber 2, causing the moisture on the surface of the absorbent cotton 5 in contact with it to be rapidly heated and vaporized, generating steam in the steam chamber 2. As steam is continuously generated, the pressure in the chamber increases, and the steam is pressure-driven to be discharged through the exhaust hole 7 into the steam storage chamber 8. In the steam storage chamber 8, the steam is temporarily stored, mixed, and buffered, and finally guided and distributed through the gas vent hole 10 on the gas vent component 9 and delivered to the operating end of the hair curler for moist heat treatment of the hair.The entire structure achieves controllable and uniform steam generation and regular transport. Through the absorbent cotton 5, liquid water is transformed into a water film that adheres uniformly to the high-temperature wall surface, avoiding direct contact between water droplets and the high-temperature surface, which would cause violent boiling, splashing, or crackling noises. The steam generation process is quieter and more stable. The steam storage chamber 8 acts as a buffer area, effectively suppressing instantaneous fluctuations during steam generation. Combined with distribution by the gas venting component 9, this helps to deliver steam with more stable flow rate and temperature. The steam can penetrate more gently, thoroughly, and evenly into the gaps between the hair shafts, effectively improving the quality of the delivered steam, enhancing the curling and styling effect, while effectively reducing heat damage and mechanical pulling to the hair, thus improving the overall user experience of the hair curler.

[0022] Furthermore, as shown in Figures 6 and 7, the PTC heating assembly 6 includes a PTC ceramic heating plate 61 and a PTC bracket 62 that fixes and supports the PTC ceramic heating plate 61. The PTC heating assembly 6 is distributed symmetrically and consists of two sets, each closely attached to the two opposing side walls of the steam chamber 2. The PTC ceramic heating plate 61 functions as a positive temperature coefficient thermistor, generating heat after energization. The heat is transferred through the PTC bracket 62, ensuring good thermal contact with the side walls of the steam chamber 2. Utilizing the inherent safety properties of the PTC ceramic heating plate 61, when the temperature reaches the Curie point, the resistance increases sharply, and the power is naturally reduced, effectively preventing overheating and dry-firing. This ensures safety, reliability, and a long service life. Additionally, symmetrical heating from both sides doubles the heating area of ​​the steam chamber 2, significantly improving heat transfer efficiency. This allows moisture supplied by the absorbent cotton 5 to be converted into steam more quickly, improving the overall response speed and steam generation rate of the device.

[0023] Furthermore, as shown in Figures 6 and 7, specifically, the water supply bracket 3 and the steam chamber 2 are positioned and connected by a connecting mechanism 4, sealing components 101 are provided at both ends of the steam cylinder 1, the absorbent cotton 5 is gripped and fixed between the water supply bracket 3 and the corresponding inner wall of the steam chamber 2, and the steam chamber 2 maintains a gap between all other wall surfaces of the steam chamber 2 and the inner wall of the steam cylinder 1, except for the surface in close contact with the absorbent cotton 5, thus forming a steam passage 11 surrounding the steam chamber 2. The water supply bracket 3 is precisely fixed inside the steam cylinder 1 through the connecting mechanism 4, ensuring that its water channel is reliably connected to an external water source, and the absorbent cotton 5 is reliably gripped between the water supply bracket 3 and the inner wall of the steam chamber 2, and this structure ensures that the absorbent cotton 5 maintains a maximum contact surface that is stable with both the water source and the heat source. The gaps that the steam chamber 2 maintains between itself and the inner walls of the steam cylinder 1 on each of its other sides, except for the side where absorbent cotton is attached, form a steam passage 11 surrounding the steam chamber, providing sufficient space for the newly generated steam to diffuse, mix, and flow. The steam enters the steam passage 11 from multiple directions within the steam chamber 2, allowing for sufficient heat exchange and pressure equalization, thus avoiding problems such as steam accumulating locally within the chamber or being unable to flow smoothly due to being discharged only along a single direction, resulting in pressure fluctuations.

[0024] Furthermore, as shown in Figures 6 and 7, it should be specifically explained that there are multiple exhaust holes 7, each located on at least one side of the steam chamber 2 where the PTC heating assembly 6 is not provided. When steam is generated in the chamber and pressure builds up, it is discharged from the exhaust holes 7 in these areas. By having multiple exhaust holes 7 instead of a single outlet, distributed steam discharge is achieved, which effectively reduces the steam velocity and flow load of a single hole and reduces high-frequency noise or turbulence generated by high-speed steam flow. In addition, by combining multiple exhaust holes with the surrounding steam passage 11, the steam can be uniformly collected and discharged in the circumferential direction of the chamber, further promoting the equalization of temperature and pressure during steam discharge and improving the stability of steam quality.

[0025] Furthermore, as shown in Figures 6 and 7, it should be specifically explained that the steam storage chambers 8 are provided on both sides of the steam cylinder 1 and each communicates with an exhaust hole 7 on the corresponding steam chamber 2. Independent steam storage chambers 8 are provided on both the left and right sides of the steam cylinder 1, and each steam storage chamber 8 communicates with the same side region of the steam chamber 2 through the corresponding exhaust hole 7. Steam discharged from both the left and right sides of the steam chamber 2 enters the two steam storage chambers 8, and the steam storage chambers 8 provided on both sides constitute a distributed buffer and a lateral distribution system. Firstly, there is no need to transport steam over long distances or concentrate it in one place, reducing flow resistance and energy loss, and avoiding mutual interference of steam flows from different paths. Secondly, the independent storage chambers on the left and right can each receive and buffer steam from their corresponding regions and discharge it independently through their venting components 9, allowing the steam to act more uniformly on the entire hair wrapped on the hair curler, avoiding localized over-humidification or overheating, resulting in a more consistent perming effect.

[0026] Furthermore, as shown in Figures 6 and 7, the gas venting component 9 is an aluminum plate 91 covering the steam storage chamber 8, and the gas venting holes 10 are multiple rows spaced apart along the length of the aluminum plate 91. The aluminum plate 91 covering the outside of the steam storage chamber 8 is used as the gas venting component 9, and multiple rows of gas venting holes 10 are machined on the aluminum plate 91. The material of the aluminum plate 91 has good thermal conductivity, which makes the temperature of the steam flowing over its surface more uniform and eliminates localized high temperatures. The multiple rows of gas venting holes 10 are arranged along the length, dividing the steam flow from the steam storage chamber 8 to obtain a large, dense steam column parallel to each other. This design greatly improves the area and uniformity covered by the delivered steam, ensuring that steam is continuously and uniformly supplied across the entire working surface of the hair curler. The steam can penetrate more gently and thoroughly into the gaps between the hair shafts, improving the user experience and the effectiveness of the hair curler.

[0027] Furthermore, as shown in Figures 1, 2, and 3, the system further includes a protective sleeve 12 fitted to the outside of the steam cylinder 1, a baffle 121 provided at a position corresponding to the gas venting component 9 of the protective sleeve 12, and the wall of the protective sleeve 12 is an object shielding portion 122 in the region facing the baffle 121. A protective sleeve 12 is fitted to the end of the steam outlet, i.e., the outside of the steam cylinder 1 and the gas venting component 9. A baffle 121 is provided in the area of ​​the protective sleeve 12 corresponding to the gas venting hole 10, and the wall of the protective sleeve 12 itself is designed as an object shield 122 without holes in the area facing the baffle 121. The baffle 121 directly blocks or disturbs the concentrated steam flow ejected from the gas venting hole 10, and the object shield 122 provides additional physical isolation. The baffle 121 changes the direction of steam ejection, diffusing and slowing it down, and mixing it with the air in the internal space of the protective sleeve 12 to cool it. The object shield 122 ensures that even if a small amount of steam passes through the baffle, it does not directly pass through the wall of the protective sleeve and eject. This limits the main area of ​​operation of the high-temperature steam to heating hair wrapped around the protective sleeve 12, thereby improving the overall protective effect.

[0028] Furthermore, as shown in Figures 3 and 5, it should be specifically explained that the protective sleeve 12 has a small straight groove 123 for inserting hair and a T-shaped groove 124 for securing the hair. The small straight groove 123 communicates with the T-shaped groove 124, and the area where the small straight groove 123 and the T-shaped groove 124 are located is on the opposite side of the baffle 121. The protective sleeve 12 is provided with a small straight groove 123 for inserting hair and a T-shaped groove 124 communicating with it, which secures and positions the hair for easy wrapping. Placing the small straight groove 123 and the T-shaped groove 124 on the other side means that the parts of the user's fingers and hands that comb, insert, and wrap their hair are mainly in contact with the lower temperature "safe side". This effectively avoids the risk of the user's hands unknowingly touching the high-temperature area during operation.

[0029] Furthermore, it should be explained in more detail that the internal water channel grooves of the water supply bracket 3 are arranged in a wave-like shape overall. By designing the water channel grooves in a wave-like shape, the water channeling effect is effectively improved, and water is supplied stably.

[0030] As can be seen from the above, this invention converts liquid water into a water film that adheres uniformly to the high-temperature wall surface through the absorbent cotton 5, avoiding the occurrence of violent boiling, splashing, or crackling noises caused by water droplets directly contacting the high-temperature surface. The steam generation process is quieter and more stable, and the steam storage chamber 8 acts as a buffer area, effectively suppressing instantaneous fluctuations during steam generation. Combined with distribution by the gas venting component 9, it helps to deliver steam with more stable flow rate and temperature. The steam can penetrate more gently, more thoroughly and evenly into the gaps between the hair shafts, effectively improving the quality of the delivered steam, enhancing the curling and styling effect, while effectively reducing heat damage and mechanical pulling to the hair, and overall improving the user experience of the hair curler.
