Description

Technical Field

[0001] This application relates to the field of hair care, and in particular to a photothermal steam hair care device. Background Technology

[0002] Hair styling devices, such as straighteners or curling irons, are household appliances that use electric current to heat an internal heating element (such as MCH, PTC, or heating wire), and then conduct heat through an aluminum or ceramic plate to achieve hair styling. They combine straightening and curling functions. They soften the hair through heating and then cool to set the style. Common types include ceramic, PTC, and MCH heating elements. Structurally, they can be divided into V-type (for both straightening and curling) and X-type, and are equipped with features such as wet / dry use and steam vents to meet different needs.

[0003] Among them, the high temperature of non-steam hair styling devices can easily damage hair; while existing photothermal steam hair styling devices use water pumps to supply water, which is not only costly and noisy, but also difficult to control the water volume. When used at certain angles, the water pump has difficulty drawing water and cannot achieve all-round water intake, thus affecting the hair styling effect.

[0004] On the other hand, existing hair styling devices do not have any therapeutic function for the scalp. Summary of the Invention

Detailed Implementation

[0032] The terms “first,” “second,” “third,” “left,” “right,” “upper,” and “lower” used in this application are not intended to limit the technical solution of this application, but are only used to distinguish and describe the various components.

[0033] See Figures 1 to 18This invention relates to a photothermal steam hair styling device. The device uses light waves and heat energy generated by a built-in light source / heating element to soften the hair, allowing it to be straightened or curled to achieve the desired style. This photothermal steam hair styling device generates steam, which reduces the impact of the high temperature of the heating element on the hair, preventing damage. Simultaneously, the light irradiates the hair and scalp, providing predetermined effects such as drying, conditioning, nourishing, promoting hair growth, and maintaining scalp health.

[0034] The photothermal steam hair styling device includes an upper clamping plate 10 and a lower clamping plate 20. One end of the upper clamping plate 10 and the lower clamping plate 20 are hinged together by a hinge assembly, so that the two clamping plates can rotate around the hinge center to realize the opening and closing action. In the closed state, a clamping plate structure is formed to hold the hair, and in the open state, it is convenient to place or remove the hair.

[0035] Both the upper clamp 10 and the lower clamp 20 are equipped with light sources / heating elements (for ease of explanation, the heating elements of the two clamps are respectively defined as the upper heating element and the lower heating element), thereby heating / illuminating the hair from opposite sides. In the following embodiments, the upper heating element 114 and the lower heating element 23 can both be light sources, or one can be a light source and the other can still be a heating element. In addition, the photothermal steam hair styling device is also equipped with a power module and a control circuit. The power module 40 includes a conductive base 41 and a power cord 42 connected to each other. The power cord is used to connect to AC power to supply power to the heating element. The control circuit 24 is connected to the conductive base and is used to control the working state of the photothermal steam hair styling device.

[0036] The light source is preferably a halogen lamp, carbon filament lamp, tungsten filament lamp, or incandescent lamp; in other embodiments, IPL, LED, or other light sources may also be used. The light source includes a light-transmitting tube and a sealed light source (such as a filament or chip) inside the light-transmitting tube, which excites the light source to generate light that is emitted outward through the light-transmitting tube.

[0037] In some embodiments, to achieve predetermined effects such as hair care, hair nourishment, hair growth, and scalp health, the light source of the photothermal hair styling device is configured with a filter element having a predetermined wavelength or band. The light generated by the light source is filtered by the filter element, and the emitted light wave has a predetermined wavelength or band that irradiates the hair or scalp. The preferred range of the wavelength or band of the filter element (or the predetermined wavelength or band of the emitted light) is 400–2300 nm, and can be any wavelength or band range within this range. For example, referring to Table 1 below, the emitted light characteristics and applications of a light source configured with a filter element are shown: Table 1. Luminous characteristics and effectiveness of light source with filter elements

[0038] To achieve the desired light waves and effects, the photothermal hair styling device of this application may employ one or more of the following three methods in combination as the filter element configured in the light source: Method 1: The filtering element is a light filter, which is placed in the optical path of the light emitted from the light source. It can be fitted to the shape of the light-transmitting tube and cover the outside of the light-transmitting tube, or placed on a light-transmitting panel (the upper heat-conducting plate 116 and / or the lower heat-conducting plate 27 can also serve as a light-transmitting panel), or placed between the light-transmitting panel and the light source. The light filter has a predetermined wavelength or band; different wavelength or band filters can be configured and interchanged to obtain different wavelengths or bands of emitted light waves to irradiate the hair or scalp, achieving different effects and solving different hair care, hair nourishment, hair growth, or scalp health problems. This method is more convenient and widely applicable, allowing for the selection of different filters to obtain more light wavelengths or bands.

[0039] Method 2: The filter element consists of a filter film coated on the inner and / or outer wall of the light-transmitting tube. The filter film has filtering properties, and the light generated by the light source is filtered by the filter film to obtain a predetermined wavelength or band to irradiate the hair or scalp. Existing optical film coating technology can be used to coat the filter film on the inner and / or outer wall of the light-transmitting tube.

[0040] Method 3: The filter element is a colored glass lamp tube, which has a filtering function. The light generated by the light source is filtered by the colored glass lamp tube to obtain a wavelength or band corresponding to the color to irradiate the hair or scalp.

[0041] In some non-limiting examples, the predetermined band or wavelength of the colored glass lamp tube is: The light source with a red translucent tube (made of red glass) has a light band or wavelength range of 620-750nm; The light source with orange translucent tubes (made of orange glass) has a light band or wavelength range of 590-620nm; The light source with a yellow translucent tube (made of yellow glass) has a light band or wavelength range of 570-590 nm; The light source with green translucent tubes (made of green glass) has a light band or wavelength range of 495-570nm; The light source with blue translucent tubes (made of blue glass) has a light band or wavelength range of 450-495nm; The light source with purple translucent tubes (made of purple glass) has a light band or wavelength range of 380-450nm; The light source with silver / black translucent tubes (made of silver / black glass) has a light band or wavelength range of 750-2400nm.

[0042] The preparation method of colored glass (colored glass lamp tubes) involves adding a colorant to the optical glass preparation steps to color the glass. A trace amount of colorant is added to the glass batch or optical glass raw materials (which may include quartz sand, soda ash, limestone, etc.), and the colored glass product is obtained after the melting, forming, and annealing steps of optical glass preparation. The preparation of colored glass or glass coloring refers to the following steps: Ingredients: A trace amount of colorant is added to the basic optical glass raw materials (such as borosilicate, quartz, soda ash, limestone, etc.); Melting: The glass batch is melted in a high-temperature furnace (about 1500-1600℃), and the colorant is uniformly dispersed in the glass melt in the form of ions or molecules; Molding and annealing: The glass melt is shaped by blowing, die casting or drawing, and then slowly cooled and annealed to obtain the final product (colored glass tube / colored glass).

[0043] In some embodiments, the above preparation method can employ existing coloring processes such as ion coloring, colloidal coloring, sandwich coloring, and diffusion coloring, adding colorants to the basic optical glass formulation and melting them together. Different coloring methods are used to adjust the type and amount of colorant to achieve the desired filtering performance.

[0044] The non-limiting examples shown in Table 2-3 below demonstrate the preparation of colored glass materials with different filtering properties, the production of which requires corresponding coloring methods and raw materials. "Light band (or wavelength)" refers to the band (or wavelength) of the emitted light after the light generated by the light source is filtered by the colored glass lamp tube.

[0045] Table 2 Examples of Colored Glass Preparation Using Colloidal Coloring Process

[0046] Table 3 Examples of colored glass prepared by ion coloring process

[0047] Light sources with colored glass tubes emit light waves with predetermined wavelengths or bands. The principle behind this is the control of light wavelengths or bands based on the color of the optical glass material. By adjusting the type and amount of colorant, the corresponding filtering function is achieved. The colored wavelengths of light range from 0 to 750 nm, the near-infrared range from 750 to 2500 nm, the mid-infrared range from 2.5 to 50 μm, and the far-infrared range from 50 to 1000 μm. The colored wavelengths range from 380 to 450 to 485 to 500 to 565 to 590 to 625 to 750 nm, corresponding to the color changes of: violet to blue to cyan to green to yellow to orange to red. By adjusting the type and amount of colorant in the optical glass formulation, colored glass or directly formed colored glass lamp tubes can be produced through optical glass manufacturing processes. The light source with the colored glass lamp tube emits light that has a predetermined wavelength or band after being filtered by the lamp tube. When it irradiates hair or skin, it achieves predetermined effects such as hair care, hair nourishment, hair growth, or scalp health.

[0048] In other embodiments, the filtering element can be a filter or a filter film. After the light emitted by the light source is filtered by the filter or filter film, the emitted light has a expected wavelength or band to irradiate the hair or skin, thus achieving the predetermined effects of hair care, hair nourishment, hair growth, or scalp health. For example, a filter or filter film can be provided between the light source and the light-transmitting panel or on the light-transmitting panel, or a filter film can be deposited on the outer and / or inner surface of the light-transmitting lamp tube.

[0049] The light source assembly of this application includes a light source and a configured filter element, so that the light generated by the light source, after being filtered by the filter element, has a predetermined wavelength or band, which, when irradiated onto the skin or scalp, has effects such as drying hair, conditioning hair, nourishing hair, promoting hair growth, or improving scalp health. The wavelength or band of light passed through the filter element can be any wavelength or band range within the range of 400–2300 nm. Different wavelengths or bands can achieve different effects. The filter element can be a single-band filter (such as 900–1800 nm, 380–450 nm, or 600–750 nm), or it can be a multi-band filter / film, for example, selecting two or more wavelength ranges (such as 380–450 nm + 900–1800 nm). Different wavelengths of light have different phototherapy effects on hair / scalp. For example, near-infrared light (900-2500nm) can stimulate blood circulation in the scalp; red light (600-750nm) can regulate biochemical enzymes in the scalp and hair follicles, such as affecting 5-alpha reductase in male pattern baldness and tyrosinase in gray hair. Since protein is a major component of hair, red light enhances nucleic acid synthesis in human tissue cells, thereby strengthening protein synthesis, promoting hair growth, and increasing hair density and elasticity. 420nm light can inhibit the growth of Malassezia and improve folliculitis. Alternatively, based on the expected health or therapeutic effects of clinically validated light wavelengths in existing technologies, corresponding filter films or filters can be selected to filter the light emitted from the light source, ensuring that the emitted light acting on the hair or skin has the desired wavelength or band.

[0050] This application's photothermal steam hair styling device (including straightening / curling / drying or other hair styling devices) uses the photothermal effect and can also utilize the heat energy of light and spatial radiation to eliminate the problems of conduction and conduction efficiency of intermediate media, so that the hair is heated quickly and instantly to achieve the effect of curling / straightening hair styling; at the same time, the effect of light source is used to assist hair styling and treatment; the light source heating is also less likely to burn the hair.

[0051] In specific applications of the filter film, it can be coated on the inner or outer wall of the light-transmitting tube of the light source. Alternatively, the filter film can be placed between the light source and the light-transmitting panel / heat-conducting plate, or it can be placed on the light-transmitting panel / heat-conducting plate.

[0052] In specific application embodiments of the filter, the inner or outer wall of the light-transmitting tube of the light source is covered with a filter; or, the filter is placed between the light source and the light-transmitting panel / heat-conducting plate, or the filter is placed on the light-transmitting panel / heat-conducting plate.

[0053] The arrangement of filters / filter films can be either plug-and-play, allowing for the replacement of filters or filter films of different wavelengths or bands in the optical path of the light emitted from the light source, or rotational switching of filters or filter films in the optical path of the light emitted from the light source. The implementation structure for rotating filters or filter films can involve fixing multiple filters to a rotatable bracket and surrounding the light source; rotating the bracket allows different filters to switch positions, moving them into or out of the optical path of the light emitted from the light source. Alternatively, filters with different wavelength ranges can be fixed to a rotatable bracket and then surround the outside of the light source tube. Rotating the bracket allows the filters with different wavelength ranges or regions to switch positions and move into or out of the light path of the light emitted from the light source. Alternatively, a roll of filters with different wavelength ranges can be mounted on a pair of spaced rotating shafts. The filter region between the pair of rotating shafts is located in the light path of the light emitted from the light source. Rotating the rotating shafts allows the filter region between the pair of rotating shafts to shift and switch positions, thus allowing filters with different wavelength ranges to move into or out of the light path of the light emitted from the light source.

[0054] On the other hand, the photothermal hair styling device of this application has light energy that can be used to quickly and instantly heat the hair when the light emitted by the light source irradiates the hair, and the light source is less likely to burn the hair when heating and drying the hair.

[0055] See Figures 1 to 18 The photothermal steam hair styling device of the present invention includes an upper clamping plate 10 and a lower clamping plate 20. One end of the upper clamping plate 10 and the lower clamping plate 20 are hinged together by a hinge assembly, so that the two clamping plates can rotate around the hinge center to realize the opening and closing action. In the closed state, a clamping plate structure is formed to hold the hair, and in the open state, it is convenient to place or remove the hair.

[0056] Please combine Figure 9 , Figure 13 and Figure 14 The hinge assembly 30 includes a hinge joint 31 formed in the upper clamping plate, a hinge seat 32 formed in the lower clamping plate 20, and a threaded connector 33. The hinge joint is inserted into the hinge seat and fastened by the threaded connector. In addition, an end cap 34 is provided on the outside of the threaded connector to improve aesthetics.

[0057] An elastic reset structure, such as a compression spring 50, is connected between the upper clamping plate and the lower clamping plate 20. After the force on the two clamping plates is removed, the two clamping plates are automatically put into an open state for easy use next time.

[0058] Understandably, both the upper clamp 10 and the lower clamp 20 are equipped with heating elements (for ease of explanation, the heating elements of the two clamps are respectively defined as the upper heating element and the lower heating element), thereby heating the hair from opposite sides. The heating element can be an electrothermal structure or a light source, using light waves to apply heat to the hair. In addition, this photothermal steam hair styling device is also equipped with a power module and a control circuit. The power module 40 includes an interconnected conductive base 41 and a power cord 42. The power cord is used to connect to AC power to supply power to the heating elements. The control circuit 24 is connected to the conductive base and is used to control the working state of the photothermal steam hair styling device.

[0059] In this invention, a water tank module 12 and a steam generator are provided on the upper clamping plate 10. The water tank module 12 stores water and provides moisture to the steam generator, thereby generating steam which is sprayed onto the outside of the upper clamping plate 10 to act on the hair, avoiding high temperature damage to the hair from the upper and lower clamping plates 20. In addition, the control circuit 24 and the control button 25 electrically connected to the control circuit 24 to switch the working state of the photothermal steam hair styling device are provided in the lower clamping plate 20.

[0060] Specifically, the upper clamping plate 10 includes an upper clamping plate body 11 and a water tank module 12. The water tank module 12 is located at the end of the upper clamping plate body 11 away from the hinge center and on the side of the upper clamping plate body 11 facing away from the lower clamping plate 20. The water tank module 12 and the upper clamping plate body 11 are detachably connected.

[0061] The water tank module 12 includes a water tank for storing water for hair styling, a water tank absorbent cotton 123, and an atomizer 124. The water tank is provided with a mist outlet 120. The water tank absorbent cotton 123 is located inside the water tank and extends along the length of the water tank. The atomizer 124 includes an atomizing plate 1241. The atomizing plate 1241 is located at the mist outlet 120 and abuts against the water tank absorbent cotton 123, thereby atomizing the water on the water tank absorbent cotton 123 into water mist and spraying it out from the mist outlet 120.

[0062] By setting up water-absorbing cotton 123 in the water tank for water absorption, it can be ensured that the photothermal steam hair styling device can fully absorb water and supply it to the atomizer 124 to produce water mist when used in any shape and angle, thus ensuring the water supply effect of the water tank module 12 and ensuring the stability of subsequent steam output.

[0063] The atomizer 124 also includes an atomizing plate holder 1242, an atomizing plate electrode 1243, and an electrode waterproof cover 1244. The atomizing plate holder 1242 is placed on the mist outlet 120 and has a cavity communicating with the mist outlet 120. The atomizing plate 1241 is embedded in the cavity. The atomizing plate electrode 1243 is electrically connected to the atomizing plate 1241. The electrode waterproof cover 1244 covers the atomizing plate electrode 1243 to achieve water and electricity isolation between the components of the atomizer 124.

[0064] In one embodiment, the atomizer 124 further includes an atomizing circuit board 1245, which is disposed on the upper clamping plate body 11 and is provided with a spring-loaded conductive post. The spring-loaded conductive post can spring to connect with the atomizing plate electrode 1243, thereby facilitating the assembly between the atomizer 124 circuit board and the atomizing plate electrode 1243.

[0065] Optionally, the water tank includes a tank body 121 and a tank cover 122 that is connected to and fitted onto the tank body 121. The mist outlet 120 is opened on the tank cover 122. During installation, the water tank is embedded into the groove reserved on the upper clamping plate body 11 with the tank cover 122 facing the lower clamping plate 20.

[0066] Please combine Figure 6 , Figure 14 and Figure 15 In one embodiment, the water tank absorbent cotton 123 is sheet-shaped, with one end near the mist outlet 120 bent to form a squeezed water outlet section, which extends above the atomizing plate 1241 and presses against the atomizing plate 1241.

[0067] Please combine Figure 15 Preferably, the housing 121 extends downward to form a squeezing rod at the position corresponding to the mist outlet 120. The squeezing rod presses the squeezed water part onto the atomizing plate 1241, thereby ensuring that the water tank absorbent cotton 123 is always in contact with the atomizing plate 1241 and ensuring the misting effect of the water tank module 12.

[0068] The water tank is also equipped with a water inlet for adding water. The water inlet is located on the tank cover 122, away from the mist outlet 120. A water inlet sealant 125 is provided at the water inlet, and the sealant 125 has a vent 126 communicating with the inner cavity of the water tank. The water-absorbing cotton 123 extends from the water inlet to the mist outlet 120. It should be noted that the vent 126 allows air to enter the water tank, but water inside the tank cannot leak out through the vent 126, thereby ensuring uniform air pressure inside and outside the water tank and guaranteeing the water absorption effect of the water-absorbing cotton 123.

[0069] Corresponding to the atomizing plate electrode 1243, the cover 122 has an electrode mounting hole 129 for the electrode to be inserted into the water tank and electrically connected to the atomizing plate 1241.

[0071] Furthermore, the water tank is also provided with a water-absorbing cotton pusher 127. The water-absorbing cotton pusher 127 is located at the end of the water-absorbing cotton away from the atomizing plate 1241 and applies a pushing force toward the atomizing plate 1241 to the water-absorbing cotton, so that the water-absorbing cotton 123 in the water tank is always in contact with the atomizing plate 1241.

[0072] In this embodiment, both the mist outlet 120 and the water inlet are located at one end of the tank cover 122.

[0073] The upper clamping plate body 11 has a gripping end 111 at one end near the hinge center and a water tank mounting groove 112 at the other end away from the hinge center. The water tank module 12 is embedded in the water tank mounting groove 112.

[0074] As mentioned above, the upper clamping plate body 11 is equipped with an upper heating element 114 and a steam generator 113. A guide hole 1171 is provided on the upper clamping plate body 11 at a position corresponding to the mist outlet 120 of the water tank module 12, allowing water mist to enter the steam generator 113. An upper heat-conducting plate 116 is provided on the side of the upper clamping plate body 11 facing away from the water tank module 12. The upper heat-conducting plate 116 contacts the upper heating element 114, dissipating the heat from the upper heating element 114 and applying it to the hair. Steam outlets 1162 are provided on both sides of the upper heat-conducting plate 116 for steam generated by the steam generator 113 to be ejected and applied to the hair. Optionally, the guide hole 1171 is the hole in the center of the water inlet sealant 117 on the upper clamping plate body 11, connecting the mist outlet 120 and the steam generator 113.

[0075] In this embodiment, the upper heating element 114 is sandwiched between the steam generator 113 and the upper heat-conducting plate 116. The upper heating element 114 heats both the steam generator 113 and the upper heat-conducting plate 116 simultaneously. There is no need to set an additional heating element for the steam generator 113. The structure of the upper clamping plate 10 is more compact, reducing the size of the upper clamping plate 10 and lowering the cost.

[0076] In this embodiment, the upper heating element 114 can also be configured as a light source (first light source), preferably a halogen lamp, carbon filament lamp, tungsten filament lamp, or incandescent lamp. In this case, the upper heat-conducting plate 116 is a light-transmitting panel made of a light-transmitting material, possessing both light transmittance and thermal conductivity, such as a transparent crystal. An opening is correspondingly provided on the lower shell 1111, and the upper heat-conducting plate 116 is secured within the opening. In this case, the light-transmitting heat-conducting plate serves as the light-transmitting panel, and the hair is positioned on the light-transmitting panel. The light emitted by the light source / upper heating element 114 is emitted through the light-transmitting heat-conducting plate 116 and irradiates the hair or scalp. The light source / upper heating element 114 can be configured with the aforementioned filter element, for example, the light source tube is a colored glass tube; or a filter film is coated on the inner and / or outer walls of the light source tube or on the inner and / or outer walls of the upper heat-conducting plate 116; or a filter is covered on the outside of the light source tube or a filter is provided on the inner or outer surface of the light-transmitting upper heat-conducting plate 116; or a filter is provided between the light source / upper heating element 114 and the light-transmitting upper heat-conducting plate 116; a socket can also be provided on the lower shell 1111, allowing different filters to be replaced by plugging and unplugging. The filter element has a predetermined wavelength or band of light, and the light emitted after being filtered by the filter element from the light source / upper heating element 114 has a predetermined wavelength or band, achieving predetermined effects such as hair care, hair nourishment, hair growth, and scalp health. At the same time, the light waves irradiate the light-transmitting upper heat-conducting plate 116, causing the light-transmitting upper heat-conducting plate 116 to heat up and accelerate hair drying.

[0077] In other embodiments, the heating element 114 may also directly employ existing electrothermal structures, such as thermistors or ceramic heating elements.

[0078] In one embodiment, the steam generator 113 includes a steam generating chamber 1131, a steam chamber absorbent cotton 1133, and a steam cover plate 1132.

The steam cover plate 1132 covers the top of the steam generating chamber 1131. The bottom of the steam generating chamber 1131 is in contact with the upper heating element 114. A steam outlet 11311 is provided at the bottom of the steam generating chamber 1131, and the steam outlet 11311 is connected to the steam outlet.

[0079] In one embodiment, the steam generating chamber 1131 is provided with granular protrusions 11313, which are distributed in an array in the steam generating chamber 1131 and are used to squeeze the water-absorbing cotton 1133 in the steam chamber, thereby increasing the rate at which the steam generator 113 generates steam.

[0080] In one embodiment, the steam generating chamber 1131 is provided with a plurality of baffles 11312, which are disposed on both sides of an array of granular protrusions, and a steam guide gap (not shown) is defined between two adjacent baffles on each side, which communicates with the steam outlet 11311.

[0081] In one embodiment, the upper clamping plate body 11 is further provided with a steam outlet sealant 115. The steam outlet sealant 115 is connected between the steam outlet 11311 of the steam generating chamber 1131 and the steam outlet 1162 of the upper heat-conducting plate 116. On the one hand, it allows the steam generated by the steam generating chamber 1131 to flow from the steam outlet to the steam outlet. On the other hand, it also prevents steam from leaking to other parts of the upper clamping plate 10, protecting the upper heating element and the electronic components on the atomizing circuit board 1245 inside the upper clamping plate 10, thereby extending the service life of the photothermal steam hair styling device.

[0082] In one embodiment, the upper heat-conducting plate 116 is provided with an embedding groove 1163, the steam outlet 1162 is opened in the embedding groove 1163, and the steam outlet sealant 115 is embedded in the embedding groove 1163.

[0083] Preferably, the upper clamping plate body 11 further includes a lower shell 1111 and an upper cover 1112. The steam generator 113, the upper heating element 114, the upper heat-conducting plate 116, and the steam outlet sealant 115 are all disposed within the lower shell 1111, wherein the upper heat-conducting plate partially protrudes from the lower shell toward the lower clamping plate 20. It is understood that steps 1161 are also provided on both sides of the upper heat-conducting plate 116 to allow it to be installed on the lower shell and partially protrude from the lower shell.

[0084] In one embodiment, the lower clamping plate 20 includes a lower clamping plate outer shell 21 and a lower clamping plate inner cover 22 that covers the lower clamping plate outer shell 21 and defines a receiving space. The receiving space is provided with a lower heating element 23, a heating element fixing plate 26, a lower heat conducting plate 27, a lower clamping plate elastic element 28, a control circuit 24, and a control button 25. The lower heat conducting plate 27, the lower heating element 23, the heating element fixing plate 26, and the lower clamping plate elastic element 28 are arranged sequentially along the direction from the upper clamping plate 10 to the lower clamping plate 20. The control button 25, the upper heating element 114, the lower heating element 23, and the atomizer 124 are all electrically connected to the control circuit 24.

[0085] In this embodiment, the lower heating element 23 can also be configured as a light source (second light source), preferably a halogen lamp, carbon filament lamp, tungsten filament lamp, or incandescent lamp. In this case, the lower heat-conducting plate 27 is made of a light-transmitting material, possessing both light transmittance and thermal conductivity, such as a transparent crystal. An opening is correspondingly provided on the inner cover 22 of the lower clamping plate, and the lower heat-conducting plate 27 is secured within the opening. In this case, the light-transmitting heat-conducting plate 27 serves as a light-transmitting panel, with the hair positioned between the upper and lower heat-conducting plates / upper and lower light-transmitting panels. The light emitted by the light source / lower heating element 23 is emitted through the light-transmitting lower heat-conducting plate 27 and irradiates the hair or scalp. The light source / lower heating element 23 can be configured with the aforementioned filter elements, such as a colored glass tube for the light source; or a filter film can be coated on the inner and / or outer walls of the light source tube or on the inner and / or outer surfaces of the lower heat-conducting plate 27; or a filter can be covered on the outside of the light source tube or a filter can be provided on the inner or outer surface of the light-transmitting lower heat-conducting plate 27; or a filter can be provided between the lower heating element 23 and the light-transmitting lower heat-conducting plate 27; or a socket can be provided on the lower clamping plate 20 to replace different filters by plugging and unplugging them. The filter elements have a predetermined wavelength or band of light, and the light emitted after being filtered by the filter elements from the light source / lower heating element 23 has a predetermined wavelength or band, achieving predetermined effects such as hair care, hair nourishment, hair growth, and scalp health. At the same time, the light waves irradiate the light-transmitting lower heat-conducting plate 27, causing the light-transmitting lower heat-conducting plate 27 to heat up and accelerate hair drying.

[0086] In other embodiments, the lower heating element 23 can also directly adopt existing electrothermal structures, such as thermistors or ceramic heating elements.

[0087] The heating module, consisting of the lower heat-conducting plate 27, the lower heating element 23, the heating element fixing plate 26, and the lower clamping plate elastic element 28, is located at the end of the lower clamping plate 20 away from the hinge center. The control circuit 24 is located at the end of the lower clamping plate 20 close to the hinge center. Preferably, a heat insulation element is provided between the heating module and the control circuit 24 to prevent the high temperature generated by the heating module from affecting the normal operation and service life of the control circuit 24.

[0088] In the embodiments of this application, the upper heating element 114 and / or the lower heating element 23 are both photothermal elements, such as halogen lamps, carbon filament lamps, tungsten filament lamps, or incandescent lamps; or, the upper heating element 114 and / or the lower heating element 23 are thermistors or ceramic heating elements.

[0089] In this invention, both the water tank absorbent cotton 123 and the steam chamber absorbent cotton are made of fine denim fiber fabric. Through their "wicking effect," they achieve omnidirectional water absorption, enabling the photothermal steam hair styling device to absorb water from various angles during use. It is understandable that the "wicking effect" is a unique property of fine denim fiber fabric. When the pores in its ultrafine fibers approach a vacuum, the fiber tube near the water end contacts water molecules, forming a fiber vacuum pore. At this time, the atmospheric pressure exceeds the vacuum inside the fiber, and water naturally accumulates in the fiber pores. The finer the fiber pores, the more pronounced the "wicking effect" and the stronger the wicking effect.

[0090] The photothermal steam hair styling device of the present invention relates to the working principle of steam: Water is added to the water tank, absorbed by the absorbent cotton 123, and then atomized by the atomizer 124 to form water mist. The water mist enters the steam generation chamber through the soft rubber inlet. At this time, the water mist comes into contact with the absorbent cotton in the steam chamber, and the water mist is converted into tiny water molecules that are drawn into the absorbent cotton in the steam chamber. When heated, the water on the absorbent cotton in the steam chamber evaporates at high temperature, changing from a water state to a steam state. Due to the steam pressure, the steam flows out through the hole at the steam outlet, that is, it is discharged to the outside of the upper clamp 10 and acts on the hair, reducing the impact of the high temperature generated by the heating elements of the two clamps on the hair and protecting the hair from damage.

[0091] The photothermal steam hair styling device of this application utilizes a light source to achieve hair styling, drying, conditioning, nourishing, promoting hair growth, or scalp health care. The underlying principle is as follows: 1. Heating using a light source: The light emitted by the light source provides direct illumination and also has heat energy. By utilizing the heat transfer between light energy and photothermal energy, the hair is heated quickly. 2. Using light wave therapy: By selecting a specific light band or wavelength colored glass lamp tube or filter element, the light emitted from the light source, after being filtered by the colored glass lamp tube or filter / film, has a predetermined light band or wavelength, which acts on the user's hair and scalp to achieve phototherapy. Preferably, the predetermined light band or wavelength range is 400–2300 nm. For example, the light bands or wavelengths and corresponding effects listed in Table 1 above, or the emitted light with a predetermined band or wavelength range such as the near-infrared band or wavelength range of 900-2500nm, can stimulate blood circulation in the head; or, 420nm light waves can inhibit the growth of Malassezia and improve folliculitis; or, the emitted light with a predetermined band or wavelength range such as red light 600-750nm can act on the user's hair and scalp, and can regulate the biochemical enzymes in the human scalp and hair follicles, such as 5-α reductase affecting male pattern baldness and tyrosinase affecting gray hair; protein is the main component of hair, and through red light, the synthesis of ribonucleic acid in human tissue cells is enhanced, thereby enhancing protein synthesis, which is beneficial to hair growth and increases hair density and elasticity.

[0092] This application describes a photothermal steam hair styling device that can be used as a curling iron and a straightener. It employs a photothermal effect, utilizing the heat energy of light and spatial radiation to eliminate the problems of conduction and conduction efficiency of intermediate media, allowing the hair to be heated quickly and instantly to achieve the effect of curling / straightening hair. At the same time, the photothermal effect is used to assist in hair styling and therapy; the light source heating is also less likely to burn the hair.
