Description

Technical Field

[0001] This utility model relates to the field of hair straightening comb technology, and in particular to a hair straightening comb. Background Technology

[0002] Chinese patent CN219742079U discloses a cold mist hair straightener, relating to the field of hair styling tools. It includes a handle assembly and a comb teeth assembly. A cold mist water tank is provided on the handle assembly and / or the comb teeth, holding liquid. An atomizer is installed on the cold mist water tank, capable of vibration to form a water mist from the liquid in the tank, which is then sprayed onto the comb teeth of the comb teeth assembly. The atomizer atomizes the water into fine particles through vibration, eliminating the need to heat the water to evaporate it and generate steam. The water mist is at room temperature, thus moisturizing the hair while avoiding the risk of burns and providing a better user experience.

[0003] In the aforementioned patent, the mist outlet is located at one end of the comb teeth. Since the comb teeth are generally dense, it is difficult for the cold mist to penetrate the comb teeth and reach the other end, which is far from the mist outlet. The atomization uniformity is poor, and the cold mist has a poor auxiliary effect on straightening hair, resulting in a significant reduction in the straightening effect when users use this product.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this invention, are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this invention are used to distinguish different objects, not to describe a particular order, and "more than" refers to two or more.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] Reference Figures 1 to 7 An embodiment of this utility model provides a hair straightening comb, including a comb handle 10 and a comb head 20. The comb handle 10 is provided with a water tank 1 and a water pump 2. The comb head 20 is provided with comb teeth 3 on the outside and a steam generating module 4 on the inside. The comb head 20 has a steam port 43a with a nozzle facing the comb tooth 3 on the outside of the comb tooth 3. The water tank 1, water pump 2 and steam generating module 4 are connected through water pipes. The steam outlet of the steam generating module 4 is connected to the steam port 43a.

[0022] In this embodiment, the comb head 20 has steam nozzles 43a facing the comb teeth 3 on the outside of the comb teeth 3. These steam nozzles 43a can be located on any side of the long side of the comb teeth 3. When the user styles their hair with the straightener, the entire strand of hair passes through the comb teeth in sequence. Therefore, the steam nozzles 43a on either side of the long side of the comb teeth 3 can provide steam to the entire strand of hair. It should be emphasized that, for the general structure of the comb teeth 3, the shape is basically a rectangular array of comb teeth. It can be understood that the steam nozzles 43a facing the comb teeth 3 on the outside of the comb head 20 can be considered as steam nozzles 43a covering the two long sides of the rectangular array. For example, the steam nozzles 43a are a double-row structure, as shown in Figure*. When in use, the steam basically covers the entire comb teeth 3, or the steam nozzles 43a can cover the entire rectangular array. Obviously, this covering structure arrangement is more effective. Additionally, the steam nozzle 43a faces the comb teeth 3, allowing the steam to directly act on the user's hair, avoiding steam waste caused by spraying in other directions. Taking Figures * and * as examples, the water tank 1 can be located at the handle 10. Since the water tank 1 is relatively heavy after being filled with water, its location at the handle shifts the center of gravity of the comb structure towards the rear, facilitating user grip and control. Preferably, the water tank 1 can be a detachable type, with a shape adapted to the handle's contour for easy water filling. It is worth noting that the steam generating module 4 can be configured to deliver steam to the steam zone at a flow rate of 0.05 ml / min to 6 ml / min.

[0023] In some embodiments, the angle between the nozzle direction of the steam port 43a and the direction of the comb teeth on the comb tooth section 3 is 10-80 degrees, for example 30-60 degrees, preferably 40 or 45 degrees.

[0024] In this embodiment, the angle between the nozzle direction of the steam outlet 43a and the direction of the comb teeth on the comb tooth section 3 is 30-60 degrees, which can basically satisfy the requirement that the steam can directly act on the user's hair after being ejected. For example, the angle between the nozzle direction of the steam outlet 43a and the direction of the comb teeth on the comb tooth section 3 is 40 degrees, 45 degrees or 50 degrees.

[0025] In some embodiments, the steam generating module 4 includes a housing 41, a flow guide 42, a steam base plate 43, and a heat source 44. The housing 41 is provided with a heat source cavity and a vaporization cavity. The heat source 44 is disposed in the heat source cavity. The inlet of the vaporization cavity is connected to the water pump 2, and the outlet of the vaporization cavity is connected to the flow guide 42. The flow guide 42 is connected to the steam base plate 43, and the steam port 43a is disposed on the steam base plate 43.

[0026] In this embodiment, the heat source chamber and the vaporization chamber can be spatially independent, that is, they are spatially isolated. The heat source part 44 is disposed inside the heat source chamber and heats the vaporization chamber through heat conduction via the shell 41. A temperature detector can be installed at the outlet of the vaporization chamber to detect the temperature of the steam when it is ejected, and the steam temperature can be controlled in conjunction with the control module.

[0027] In some embodiments, the housing 41 includes a main housing 411, a front cover 412, and a rear cover 413; wherein, The main shell 411 is a double-layered, multi-cavity structure with both ends open. The upper layer has a parallel auxiliary vaporization cavity 4112 and a main vaporization cavity 4111, and the heat source cavity is located in the lower layer. The rear cover 413 seals the rear end of the main housing 411, and the rear cover 413 is provided with a connecting groove 4131 connecting the auxiliary vaporization chamber 4112 and the main vaporization chamber 4111; the front cover 412 seals the front end of the main housing 411, and the front cover 412 is provided with an interface for connecting the water pump 2; the outlet of the auxiliary vaporization chamber 4112 is connected to the inlet of the guide section 42.

[0028] In this embodiment, the main housing 411 is made of a good thermal conductor, such as ceramic, stainless steel, aluminum, copper, aluminum alloy, titanium alloy, or other alloys. Combined with the aforementioned material selection, the heat source 44 can be positioned within the heat source cavity, and the vaporization cavity is heated by the heat conducted through the housing 41. Preferably, the box-shaped structure is elongated, and the dual-cavity heating mode of the auxiliary vaporization cavity 4112 and the main vaporization cavity 4111 allows for a longer vaporization time, facilitating the complete vaporization of water. Furthermore, combined with the sensor settings of the aforementioned embodiment, more precise control of the steam temperature can be achieved.

[0029] In some embodiments, the secondary vaporization chamber 4112 includes a first secondary vaporization chamber 41121 disposed to the left of the main vaporization chamber 4111 and a second secondary vaporization chamber 41122 disposed to the right of the main vaporization chamber 4111; the flow guide 42 includes a first flow guide 421 and a second flow guide 422; and the steam substrate 43 includes a first steam substrate 431 and a second steam substrate 432. The main vaporization chamber 4111 is connected to the first auxiliary vaporization chamber 41121 and the second auxiliary vaporization chamber 41122 respectively through the connecting groove 4131 on the rear cover 413. The outlet of the first auxiliary vaporization chamber 41121 is connected to the inlet of the first guide section 421, and the outlet of the second auxiliary vaporization chamber 41122 is connected to the inlet of the second guide section 422. The outlet of the first guide section 421 is connected to the steam port 43a on the first steam substrate 431, and the outlet of the second guide section 422 is connected to the steam port 43a on the second steam substrate 432.

[0030] In this embodiment, the steam port 43a is configured as a double-row structure arranged on the comb tooth section 3. The steam is diverted through the first secondary vaporization chamber 41121 and the second secondary vaporization chamber 41122 and then sent to the steam ports 43a on both sides of the comb tooth section 3 for ejection. The combination of the front cover 412 and the rear cover 413 makes the main shell 411 easier to demold and simplifies the manufacturing process.

[0031] In some embodiments, the first flow guide 421 is provided with a first heat insulation plate 4211 extending inward, and the second flow guide 422 is provided with a second heat insulation plate 4221 extending inward. After the first flow guide 421 and the second flow guide 422 are both assembled with the main housing 411, the first heat insulation plate 4211 and the second heat insulation plate 4221 wrap around the bottom of the main housing 411.

[0032] In this embodiment, as described in the foregoing embodiments, it is easy to see that the main housing 411 needs to vaporize water during operation, resulting in a high operating temperature. Many other structures in the hair straightener do not require such high temperatures. Furthermore, high temperatures can affect the lifespan of other components. Therefore, the first guide section 421 and the second guide section 422 are preferably made of materials with good heat insulation, such as silicone or other similar plastics or composite materials. The first guide section 421 and the second guide section 422 are respectively located on the left and right sides of the main housing 411, preventing high temperatures from escaping from the left and right sides of the main housing 411. Simultaneously, the first heat insulation plate 4211 and the second heat insulation plate 4221 are installed, and after assembly, they wrap around the lower side of the main housing 411. Finally, using a heat-insulating front cover 412 and a rear cover 413 achieves the desired heat insulation effect. It should be noted that the upper part of the main housing 411 is generally the heating element of the comb teeth, which does not need to be heat-insulated. At the same time, the heating element of the comb teeth can also have a positive effect on the atomization of the main housing 411. In some products where the comb teeth do not need to be heated, a heat insulation plate can also be installed on the upper part.

[0033] In some embodiments, the main housing 411 further includes a front gasket 414 and a rear gasket 415. The front cover 412 is connected to the main housing 411 via the front gasket 414, and the rear cover 413 is connected to the main housing 411 via the rear gasket 415. The front gasket 414 and the rear gasket 415 enhance the sealing effect.

[0034] In some embodiments, the main vaporization chamber 4111 includes a first main vaporization chamber 41111 and a second main vaporization chamber 41112. The first main vaporization chamber 41111 is connected to a first auxiliary vaporization chamber 41121 via a connecting groove 4131 on the rear cover 413, and the second main vaporization chamber 41112 is connected to a second auxiliary vaporization chamber 41122 via a connecting groove 4131 on the rear cover 413. In conjunction with the foregoing embodiments, the main vaporization chamber 4111 can be a single vaporization chamber connected to two auxiliary vaporization chambers 4112 via a branch connection, or it can be two independent vaporization chambers, as illustrated in the examples above.

[0035] In some embodiments, the vapor substrate 43 is formed by a row of tubular first channels on a strip substrate, the flow guide 42 has a strip inlet and a row of tubular second channels, the outlet of the secondary vaporization chamber 4112 is a strip outlet, the strip inlet of the flow guide 42 is connected to the strip outlet of the secondary vaporization chamber 4112, and the second channels are respectively connected to the first channels.

[0036] In this embodiment, the inlet of the guide section 42 is configured as a strip-shaped inlet, and the outlet of the secondary vaporization chamber 4112 is configured as a strip-shaped outlet. In particular, during assembly, an interference fit can be used, or a rubber ring can be added to enhance the sealing effect.

[0037] This hair straightening comb, by incorporating a steam function, achieves the following effect when straightening hair compared to the dry heat straightening effect of conventional electric heating plates: I. Steam reduces heat damage The thermal buffering effect of moisture Steam (100°C water vapor) can form a high-temperature water film on the surface of the hair, reducing direct heat damage through the following mechanisms: Uniform heat transfer: Steam has better thermal conductivity than dry heat, avoiding local overheating (such as "hot spots" caused by uneven contact of traditional clamps).

[0038] Gentle warming: When water vapor releases latent heat (heat of vaporization), the temperature stabilizes at around 100°C, slowing down the rate at which the hair heats up and reducing sudden denaturation of keratin.

[0039] Maintain hair moisture content Traditional high-temperature tools quickly evaporate the moisture inside the hair, causing the hair cuticles to dry and crack. Steam, on the other hand, can replenish moisture while heating, reducing cuticle lifting (reducing friction and static electricity).

[0040] Protection of disulfide bonds A steam environment may delay the breaking temperature of disulfide bonds (above 140°C), relying more on hydrogen bond recombination rather than covalent bond destruction in the 100-140°C range, thereby reducing permanent damage.

[0041] II. Steam Enhancement of Straight Hair Effect (Taking Straight Hair in Hair Styling as an Example) Enhance the plasticity of keratin When moisture penetrates the hair cortex, it weakens hydrogen bonds and temporarily stretches the keratin structure, making the hair more susceptible to stretching and deformation under external forces (such as the tension of a hair straightener). Experiments have shown that in environments with humidity levels above 50%, the yield strength of hair decreases by approximately 30%.

[0042] Temporary softening of hair cuticles Steam softens the cuticle layer of hair, making the hair surface smoother and reducing friction resistance when the flat iron is used, thereby improving the smoothness and shine of straightened hair.

[0043] Thermo-hydraulic synergy Steam stage (100℃): Opens the hair cuticles and softens the hair.

[0044] Combing stage (100-140℃): Styling is done when the hair is in a highly malleable state, requiring a lower temperature than traditional dry heat (180℃-230℃).

[0045] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
