Description

A photothermal air comb Technical Field

[0001] The present application relates to the technical field of hairdressing tools, and in particular to a photothermal air comb. Background Art

[0002] The principle of drying hair by traditional hair dryers is to suck in cold air through the fan and blow it out from the fan outlet. The cold air is heated by the high-power heating element and then blown quickly toward the hair through the air outlet. The moisture in the hair is heated and evaporated, or carried away by the fast-flowing hot air, thus achieving the purpose of drying hair. However, traditional hair dryers have high power and waste a lot of electricity. The temperature of the heating wire / plate is high, which increases the risk of burns to the skin and hair damage during use. The higher the power of the hair dryer, the higher the temperature, and the more likely it is to damage the hair and scalp. When the hair is wet, the outer structure of the hair scales is open (the function of the hair scales is to protect the nutrients inside the hair). When the hair scales are open, the high temperature directly acts on the hair fiber and hair core, causing the water in the hair medulla to evaporate quickly (the function of the hair medulla is to affect the gloss and color depth of the hair, and high temperature causes its dye to change), causing the hair to lose its luster and turn yellow and split. The higher the power and temperature of the hair dryer, the faster the hot air is applied to the hair, and the higher the speed requirement of the fan, the greater the noise generated, and the cost increases accordingly. In order to meet the power requirements of high-power heating and high-speed fans, the instrument cannot be powered wirelessly, which increases the difficulty of storage and greatly reduces the convenience of use.

[0003] A hot air comb is an improved version of a hair dryer. This hair care appliance not only dries hair but also combs and massages the scalp, making it an essential hairdressing accessory. However, existing hot air combs connect the comb head to the body through an interference fit and hot ironing. This interference fit requires high machining tolerances for the comb head and body, making relative rotation of the comb head and body difficult and inconvenient to control. The hot ironing operation is inefficient and cumbersome to operate. Existing hot air combs also sterilize using infrared lamps installed in the body, but the light irradiating the comb head is too diffuse to be effective. Furthermore, existing hot air combs are complex in structure and difficult to carry. Technical issues

[0034] Referring to Figures 1-12, the present application relates to a solar thermal comb 100. The comb head 1 and handle 10 are formed into a straight rod-shaped unit, including an outer shell, a main control board 20 mounted within the inner cavity of the shell, and a lamp 30, a blower 40, and a battery 50 electrically connected to the main control board 20. The outer shell is divided into a comb head housing and a handle housing. A through hole 14 is provided in the outer shell for receiving a power supply port 21. The charging port 21 is provided on or electrically connected to the main control board 20. The power supply port 21 extends through a through hole in the outer shell to connect to an external power source for charging the battery 50 or powering the main control board 20. The solar thermal comb 100 also includes a button assembly (not shown) electrically connected to the main control board 20 for operating the comb 100 or setting its functions. The comb head 1 is provided with a lamp slot 15, within which the lamp 30 is mounted. The comb 1 is also equipped with a set of comb teeth 13 for dividing hair into small sections. Hair hangs on the comb teeth or in the spaces between the teeth to form a hair zone, allowing ventilation. An opening 150 is provided on the side of the lamp slot facing the comb teeth, serving as a vent and light outlet. Hot air heated by the lamp 30 is blown through the opening 150 toward the hair zone on the comb teeth and through the spaces between the hair. Light emitted by the lamp 30 illuminates the hair zone through the opening 150. The lamp 30 can be a tungsten filament lamp or a carbon fiber lamp, and there should be at least one lamp. Hair drying is achieved by utilizing the heat and light energy of the lamp 30. A set of comb teeth 13 can be arranged in multiple rows, each with spaces between them. These spaces include the spaces between adjacent individual comb teeth and the spaces between adjacent rows of comb teeth. Light generated by the lamp 30 is emitted from the side openings 150 of the lamp tube slot 15 to illuminate the hair area for light drying. Hot air flows from the lamp tube slot 15 through the side openings 150 toward the hair area for hot air drying. The comb housing is provided with a ventilation channel 11. The ventilation channel 11 can be arranged to correspond to the spaces between the rows of comb teeth and is in air communication with the lamp tube slot 15 through the openings 150, the spaces between the comb teeth, and the hair area on the comb teeth.

[0035] The tungsten filament lamp tube or carbon fiber lamp tube 30 uses a tungsten filament or carbon fiber as the filament, or luminescent material. The filament is mounted within a transparent lampshade and emits light when electricity is applied. The lampshade is kept in a vacuum or filled with a low-pressure inert gas or halogen gas to prevent the filament from oxidizing at high temperatures. When a halogen gas such as iodine or bromine is filled within the transparent lampshade of the tungsten filament lamp tube or carbon fiber lamp tube, a halogen lamp (also known as a tungsten-halogen lamp) is obtained. Tungsten filament lamp tubes or carbon fiber lamp tubes are incandescent lamps and utilize the structure of an incandescent lamp. Using tungsten filament and / or carbon fiber as the luminescent material, or filament, a certain proportion of inert gas or halogen gas can be filled within the transparent lampshade to increase the lamp life. The spectral distribution of the tungsten filament and / or carbon fiber lamp tube can be adjusted by adjusting the gas pressure and gas ratio within the lamp, the current pulse, or the supply voltage. Preferably, the carbon-tungsten filament lamp tube and / or carbon filament lamp tube 30 of the photothermal air comb 100 of the present application utilizes a halogen lamp tube.

[0036] The heat energy generated by the tungsten filament lamp tube or carbon fiber lamp tube 30 can heat the cold air sucked in by the fan 40 into hot air. When the hot air blows towards the hair, it evaporates or carries away moisture, thereby drying the hair. On the other hand, the light generated by the tungsten filament lamp tube or carbon fiber lamp tube 30 contains 900-2500nm near-infrared light, which can be absorbed by water molecules and cause high-frequency vibrations to generate internal heat, causing water to evaporate. By irradiating wet hair with its near-infrared light waves, the water molecules on the hair surface generate internal heat and evaporate, thereby achieving the effect of assisting in drying the hair.

[0037] The photothermal air comb 100 of the present application utilizes one or more tungsten filament or carbon fiber lamps 30 mounted on a combing head 1. Specifically, the combing head housing is provided with a lamp slot 15, within which the lamps 30 are mounted. The lamp slot 15 has openings 150 along its length, facing the comb teeth 13 to provide airflow communication between the teeth and the hair area. This allows light from the lamps 30 within the slot 15 to illuminate the hair area on the comb teeth. The openings 150 serve as ventilation and as a light outlet for the lamps 30, allowing light from the tungsten or carbon fiber lamps 30 to exit through the openings 150 for close-range illumination of the hair area. The lamps 30 are positioned so that they can be as close to the hair as possible during hair drying. The combing head 1 can accommodate multiple tungsten and / or carbon fiber lamps 30, and multiple lamp slots 15 can be provided, each housing a lamp 30. The sidewall of each lamp tube slot 15 is provided with an opening 150 along the length direction. It is understood that the opening 150 can be in various forms, for example, a long slot or an open hole, or a group of through holes.

[0038] The main control board 20 and the battery 50 are installed in the handle 10 (handle housing). A partition 17 can be provided in the handle housing to separate the main control board 20 and the battery 50 from the fan 40 to seal and protect the main control board 20 and the battery 50.

[0039] The fan 40 can be installed in the handle 10 or in the combing head 1. The fan 40 comprises a housing and rotating blades within the housing. Ventilation ports 42 and 43 are located at either end of the housing (i.e., the top and bottom ends along the fan's rotational axis), serving as the fan's air inlet and outlet. These ports communicate with the internal cavity of the housing to form the fan's air duct. In other embodiments, the vents 42 and 43 are also located on the side facades of the fan housing.

[0040] In some embodiments, the housing of the photothermal comb 100 may further include ventilation holes 12. The ventilation holes 12 may be located in the comb housing or the handle housing. External air flows into the photothermal comb 100 through the ventilation holes 12. In this case, the ventilation holes 12 serve as air inlets, and the ventilation channels 11 provided in the comb housing serve as air outlets. In other embodiments, the ventilation holes 12 may not be provided. In this case, the ventilation channels 11 may serve as circulating vents for both air intake and air outlet.

[0041] The battery 50 is a rechargeable battery or a removable primary battery. The power interface 21 can be connected to an external power source to directly power the photothermal air comb 100 or charge the battery 50.

[0042] In some embodiments, an air inlet 151 can be formed at one end of the lamp tube slot 15, providing airflow communication with the air duct of the fan 40. By providing the air inlet 151 and the side opening 150, the lamp tube slot 15 (i.e., the space outside the lamp tubes) connects to the air duct of the fan 40, the spaces between the comb teeth, and the hair area on the comb teeth. The air inlet 151 and the opening 150 of the lamp tube slot 15 can be separate ventilation holes, or they can be shared, for example, with the opening 150 serving as both an air inlet and an air outlet. The airflow between the ventilation holes 12, the fan 40, the lamp tube slot 15 (the space outside the lamp tubes 30), the spaces between the comb teeth, the hair area on the comb teeth, and the ventilation channel 11 forms the hair drying airflow path 200 of the thermal hair comb 100. In other embodiments, a circulating air path is formed between the spaces between the comb teeth, the hair area on the comb teeth, the ventilation channel 11, the air duct of the blower 40, and the lamp tube slot 15, serving as the hair drying airflow path 200 of the photothermal air comb 100. The hair on the comb teeth is dried by the hot air flowing out of the side openings 150 of the lamp tube slot 15, while the light generated by the lamp tube 30 illuminates the hair area through the side openings 150 of the lamp tube slot, providing light-assisted hair drying. The arrows in Figures 4-6 and 10-11 indicate the airflow path 200. The arrows in Figure 7 represent a schematic diagram of the light generated by the light source (lamp tube 30) irradiating the hair area.

[0043] 1-7 , the photothermal air comb 100 of the first embodiment of the present application includes a comb head 1 and a handle 10 , which is generally in the shape of a straight rod. Its outer shell is formed by assembling an upper shell 101 and a lower shell 102 , which are respectively divided into a comb head shell and a handle shell. The handle is cylindrical (but not limited to a cylindrical shape), and the comb head is a rectangular parallelepiped (but not limited to a rectangular parallelepiped). Accordingly, the upper shell 101 and the lower shell 102 corresponding to the handle portion are semi-cylinders (but not limited to semi-cylinders) separated along the length direction, and the corresponding comb head portion is a rectangular parallelepiped (but not limited to a rectangular parallelepiped). The comb head 1 is equipped with three rows (but not limited to three rows) of comb teeth 13 for dividing hair into small portions. The hair is suspended on the comb teeth or in the spaces between the comb teeth to form a hair zone, and the hair zone is ventilated by the gaps between the hair.

[0044] The upper shell 101 is an annular housing in the combing section. The lower shell 102 has two slots (or lamp tube slots 15) formed on either side of the combing section (in the longitudinal direction). When the upper shell 101 is placed over the lower shell 102, the tops of the slots are sealed. Each of the two lamp tube slots 15 houses a lamp 30. Openings 150 are formed along the sides of the lamp tube slots 15 along their lengths, serving as light outlets for the lamp 30 and air outlets for the lamp tube slots 15. Two through slots are formed along the length of the lower shell 102 in the middle of the combing section, forming ventilation channels 11. These ventilation channels 11 are connected to the side openings 150 of the lamp tube slots through the gaps between the comb teeth and the hair area on the comb teeth. When the upper shell 101 and lower shell 102 are assembled, a rectangular (but not limited to rectangular) shape is formed in the combing section. The two lamp tube slots 15 are arranged parallel to each other along their lengths. The lower housing 102 is equipped with three rows of teeth 13 on the bottom surface of the comb head portion, with the outer two rows of teeth angled outward. Two through slots are defined between adjacent rows of teeth 13, forming a ventilation channel 11. The ventilation channel 11 is an oblique slot and angled toward the side opening 150 of the lamp tube slot 15. This facilitates airflow within the lamp tube slot 15 to flow smoothly from the opening 150 through the gaps between the teeth and the hair area above them, then to the ventilation channel 11 and out through the outlet ventilation channel 11. In this embodiment, the airflow from the outlet ventilation channel 11 is directed upward (away from the teeth) and out of the comb head. Referring to Figure 6, the arrows indicate the light-emitting interval. Since a low-power carbon tungsten filament lamp tube and / or carbon filament lamp tube 30 is used, when in use, the lamp tube 30 is in very close contact with the hair on the comb teeth. The heat energy of the lamp tube heats the air flow that blows into the hair area, and the near-infrared light contained in the light generated by the light source irradiates the hair at close range, thereby achieving efficient hair drying without causing the problem of hair damage caused by high-power photothermal hair dryers.

[0045] After the upper shell 101 and the lower shell 102 are assembled, a cylindrical handle housing is formed corresponding to the handle portion. A vibration-damping ring 41 is provided on the outside of the fan 40 and is installed in the handle housing. The fan 40 is coaxially installed in the handle housing. The fan vent 42 is in airflow communication with the ventilation hole 12 of the photothermal air comb 100. With reference to Figure 5, the fan vent 42 is located at the ventilation hole 12 of the photothermal air comb 100. When the ambient cold air is sucked into the shell from the ventilation hole 12, it is sucked into the fan's air duct from the fan vent 42 and discharged from another ventilation hole 43 of the fan; the fan vent 43 is located at the air guide channel 16 formed in the shell at the connection between the comb head 1 and the handle 10 and is in airflow communication. The air guide channel 16 formed in the shell at the connection between the comb head 1 and the handle 10 is in airflow communication with the lamp tube groove 15. The size of the fan 40 is adapted to the size of the cavity in the outer shell of the photothermal air comb 100, specifically to the inner cavity of the handle shell, and is coaxially installed in the handle 10 along the axis (or length) direction of the photothermal air comb 100.

[0046] The main control board 20 and the battery 50 are installed in the rear section of the handle housing. A partition 17 is provided on one side of the ventilation hole 12 (opposite to the fan 40), and another partition 17 is provided near the tail end of the handle housing. The two partitions 17 install the main control board 20 and the battery 50 in the handle housing and separate them from the fan 40 and the combing head 1.

[0047] With reference to Figures 4-6 , the arrowed airflow paths in the figures illustrate the following airflow path 200 of the photothermal hair comb 100 of this embodiment: Under the suction / exhaust action of the blower 40 , ambient air (cold air) is drawn in through the ventilation holes 12 , drawn into the blower 40 through the blower vent 42 , and then flows from the blower's other vent 43 through the air guide duct 16 into the lamp tube slot 15 through the air inlet 151 . The hot air is then heated by the heat energy generated by the lamp 30 to form hot air. The hot air then flows out of the opening 150 of the lamp tube slot 15 , acting on the hair area on the comb teeth. The hot air then flows through the gaps between the comb teeth 13 and the hair area on the comb teeth, and then out through the inclined ventilation channel 11 , drying the hair as it passes through the hair area. In this embodiment, the airflow path 200 enters the handle and flows into the comb head 1 along the length of the handle.

[0048] 7 , the arrows indicate the direction of light irradiation. The middle area corresponding to the two arrow lines starting from the lamp tube 30 in the figure represents the range of light irradiation. The light emitted by the lamp tube 30 irradiates the hair area on the comb teeth 13 from the side opening 150 of the lamp tube groove 15, thereby achieving near-infrared light-assisted hair drying.

[0049] The light-heat air comb 100 of this embodiment has the following principles for drying hair:

[0050] 1) Near-infrared light effect: Near-infrared light of 900-2500nm is absorbed by water molecules and generates high-frequency vibrations, generating internal heat that evaporates the water. Using a tungsten filament lamp or a carbon fiber lamp (such as a halogen lamp) 30, the near-infrared light waves emitted by the lamp are irradiated on wet hair. The light waves react with the water molecules on the surface of the hair to generate internal heat, which promotes evaporation of water on the hair surface, thereby assisting in drying the hair.

[0051] 2) Thermal Energy Effect: Cool air is drawn in by the fan 40 and flows through the fan vents into the space outside the tungsten filament lamp tube or carbon fiber lamp tube (e.g., halogen lamp tube) 30, i.e., into the lamp tube slot 15. The cooling air is heated into hot air by the thermal effect of the light field of the tungsten filament lamp tube or carbon fiber lamp tube (e.g., halogen lamp tube) 30, and then flows into the hair area for hot air drying or to blow away moisture. Simultaneously, the comb teeth are used to divide the hair into several small portions, thereby increasing the contact area between the hot air and the hair and the flow rate of the hot air. After flowing through the hair area, the hot air flows out through the ventilation channel 11.

[0052] Referring to Figures 8-12, the second embodiment of the present application shows a photothermal air comb 100 comprising a comb head 1 and a handle 10. The comb head 10 is generally in the shape of a straight rod. Its outer shell is formed by assembling an upper shell 101 and a lower shell 102, which are respectively divided into a comb head housing and a handle housing. The handle is cylindrical (but not limited to cylindrical), and the comb head is a rectangular parallelepiped (but not limited to rectangular parallelepiped). Accordingly, the upper shell 101 and the lower shell 102, corresponding to the handle portion, are semi-cylindrical and separated along the length, while the comb head portion is divided into a rectangular parallelepiped. The comb head 1 is equipped with three rows (but not limited to three rows) of comb teeth 13, with spaces between the teeth. The comb teeth 13 are used to divide hair into small portions. Hair is suspended on the comb teeth or in the spaces between the teeth to form a hair zone, and the gaps between the hair are ventilated. The comb head 1 is provided with a ventilation channel 11, which corresponds to the spaces between the rows of comb teeth and is connected to the lamp tube slot 15 through an opening 150, the spaces between the comb teeth, and the air path of the hair zone.

[0053] The upper shell 101 forms a cavity within the combing head portion of the housing. A fan bracket 19 is provided at the bottom of the cavity, and the fan 40 is mounted on the fan bracket 19. An air guide 103 is provided at the top of the cavity. The air guide 103 covers the top of the upper shell 101, sealing the fan 40 within the cavity of the upper shell 101. The air guide 103 is compatible with the combing head housing, that is, it is compatible with the housing of the upper shell 101 in the combing head portion. In the orientation shown in the figure, when the upper shell 101 is placed horizontally, the fan 40 is installed in a vertical direction, that is, the fan 40 is installed perpendicular to the axis (length) of the wind, light and thermal air comb 100. A guide channel is formed inside the air guide 103, allowing air to circulate between the vent of the fan 40 and the lamp tube slot 150.

[0054] The lower shell 102 has two slots along its length, forming lamp tube slots 15. Each slot 15 houses a lamp tube 30. When the air guide 103, upper shell 101, and lower shell 102 are assembled, the lamp tube slots 15 (i.e., the space outside the lamp tubes 30) communicate with the cavity within the upper shell 101 and the interior of the air guide 103. Openings 150 are formed along the sides of the lamp tube slots 15 along their lengths, serving as light outlets for the lamp tubes 30 and ventilation for the lamp tube slots 15. Two through slots along the length of the middle housing of the lower shell 102 form ventilation channels 11. These channels connect to the side openings 150 of the lamp tube slots through the gaps between the comb teeth and the hair areas on the comb teeth, and also to the airflow of the blower 40. When the upper shell 101 and the lower shell 102 are assembled, a rectangular (but not limited to rectangular) shape is formed in the combing section. Two lamp tube slots 15 are arranged parallel to each other along the length of the combing section. The lower shell 102 is equipped with three rows of comb teeth 13 on the bottom surface of the combing section, with the outer two rows of teeth angled outward. Two through slots are defined between adjacent rows of comb teeth 13 to form ventilation channels 11. Each row of comb teeth consists of multiple individual teeth. The spaces between the teeth and the hair areas above the teeth are in airflow communication with the ventilation channels 11 and with openings 150 in the sidewalls of the lamp tube slots. The ventilation duct 11 is an inclined slot, angled toward the side opening 150 of the lamp tube slot 15. This facilitates airflow from the lamp tube slot 15, exiting through the opening 150, passing through the spaces between the comb teeth and the hair area (ventilating the spaces between the hairs), and flowing smoothly into the ventilation duct 11. Air then exits the ventilation duct 11 and the fan's vent 43, flows into the fan 40, and exits through another vent 42 of the fan 40. The hot air is then directed through the guide channel within the air guide cover 103 to the surface of the lamp tube 30 within the lamp tube slot 15. The hot air then flows through the outlet 150, passing through the spaces between the comb teeth and the hair area, and reenters the ventilation duct 11. This cycle of air circulation dries the hair area on the comb teeth. In this embodiment, when the upper and lower shells 101 and 102 are assembled, a gap is formed in the comb head, serving as an auxiliary vent 18. External cool air is drawn into the fan 40 duct through the auxiliary vent 18. When the fan 40 is operating, it simultaneously draws in external cool air through the auxiliary vent 18 and the spaces between the comb teeth / hair area. In this embodiment, the dry hair airflow circulates only in the combing head, and there is no airflow in the handle. The air path between the inside of the combing head shell and the inside of the handle shell can be separated by the side wall of the shell. For example, the upper shell 102 is provided with a partition 17 in the tail of the combing head part to further block the airflow in the combing head 1 and the handle 10 and protect the main control board 20 and the battery 50.

[0055] The upper shell 101 and the lower shell 102 are assembled to form a cylindrical handle housing corresponding to the handle portion. The main control board 20 and the battery 50 are mounted in the handle housing. The main control board and the battery can be installed in the handle by providing a partition 17 in the handle housing. The handle housing is provided with a through hole 14, and the charging port 21 is electrically connected to the external power supply through the through hole 14.

[0056] 10-11 , the arrows in the figures indicate the hair drying airflow path 200 : when the fan 40 is activated, external cold air is drawn in from the gaps between the comb teeth and the hair area on the comb teeth, enters the fan 40 through the ventilation duct 11, and flows to the two lamps 30 through the fan vent 42. The thermal energy effect of the light field of the lamp 30 (a tungsten filament or carbon filament light source, such as a halogen lamp) heats the cold air flowing over the surface of the lamp 30 (i.e., within the lamp slot 150) into hot air. The hot air then flows through the hair area, completing the first cycle of the airflow and entering the next cycle. After flowing through the hair area, the hot air flows out through the ventilation duct 11 and is again drawn into the fan 40. It flows through the fan vent 42 to the two lamps 30 for a second heating to form hot air. The hot air flows through the hair area again and then flows out through the ventilation duct 11 to enter the next internal cycle. This cycle is repeated, resulting in a short heating time for the flowing air, high thermal stability, and more moisture carried away.

[0057] Specifically, under the blower 40, external cold air is drawn in through the gaps within the hair area on the comb teeth and the spaces within the comb teeth. The cold air is then drawn into the blower 40 through the ventilation duct 11 and the blower vents 43. The cold air is then directed through the blower vents 42 and into the lamp tube slot 15 from the air guide cover 103. The heat energy effect of the light field from the lamp tube 30 (a tungsten filament or carbon filament light source, such as a halogen lamp) heats the cold air flowing over the surface of the lamp tube 30 into hot air. The hot air then flows into the hair area through the side openings 150 of the lamp tube slot 15. The comb teeth 13 divide the hair into several small portions, thereby increasing the contact area between the hot air and the hair and the flow rate of the hot air. After the hot air flows through the hair area, it flows out through the ventilation channel 11 and is then sucked back into the fan 40 through the fan vent 43 (the airflow in the first cycle is slightly hotter than the initial ambient airflow). The hot air then flows through the fan vent 42 to the tungsten or carbon filament light source lamp 30 for a second heating to form hot air. The hot air then flows through the hair area again (at this point, the hair has less surface moisture due to the near-infrared light than in the first cycle, and the external heat energy required by the hair is correspondingly reduced). The hot air then flows out through the ventilation channel 11 and enters the next internal cycle (this cycle is repeated, resulting in a shorter heating time for the flowing air, higher thermal stability, and more moisture carried away).

[0058] The photothermal air comb 100 of this embodiment is provided with an auxiliary air flow path for drying hair, referring to FIG10 : under the action of the fan 40 , external cold air is sucked in from the auxiliary vent 18 of the comb housing, and is sucked into the fan 40 through the ventilation channel 11 , participating in the above-mentioned air flow circulation for drying hair.

[0059] The principle of drying hair using the light-heat air comb 100 in this embodiment is as follows:

[0060] 1) Near-infrared light effect: Near-infrared light of 900-2500nm is absorbed by water molecules, causing high-frequency vibrations to generate internal heat, which evaporates the water. A lamp tube 30 using a tungsten or carbon filament light source is used to irradiate wet hair with its near-infrared light waves. The light waves react with the water molecules on the hair surface to generate internal heat, which promotes evaporation of water on the hair surface. The light generated by the light source passes through the side openings 15 of the lamp tube slot 15 and irradiates the hair hanging on the comb teeth, thereby achieving the effect of assisting hair drying.

[0061] 2) Thermal Energy Effect: Cool air is drawn in by the fan 40 and flows through the fan vent 4 to the lamp (tungsten or carbon filament light source) 30. The thermal energy effect of the light field of the lamp 30 heats the flowing cool air into hot air, which then flows to the hair area. Simultaneously, the comb teeth divide the hair into several small portions, thereby increasing the contact area between the hot air and the hair and the flow rate of the hot air. After flowing through the hair area, the hot air flows out through the ventilation channel 11 (serving as a circulating air outlet) and is then drawn back into the fan through the fan vent. It then flows through the fan vent to the tungsten or carbon filament light source for a second heating, forming hot air that flows through the hair area again. This cycle is repeated, resulting in a shorter heating time for the flowing air, higher thermal stability, and a greater removal of moisture molecules.

[0062] 3) Circulating air suction: Because traditional hair dryers need to be held at a certain distance from the head, some of the heat dissipated by the wind is lost to the surrounding air and does not effectively affect the hair. Furthermore, throughout the drying process, traditional hair dryers must draw in cold air from the surrounding air, which is heated by the heating element and then radiated to the hair through the air. This heat loss and continuous input of cold air significantly increases the product's power consumption and reduces hair drying efficiency.

[0063] This embodiment uses circulating heated air to improve the timeliness of hair drying. The beneficial effect of circulating heating is that as the hair becomes less and less hydrated and drier in the latter stages of the drying process, the heat consumed by the hot air acting on the hair becomes less and less. Therefore, the power consumption required in the latter stages of the drying process becomes less and less, the heat is maintained at a high level, and the heating time is shortened, effectively improving the utilization rate of thermal energy and reducing thermal energy waste.

[0064] In the above embodiments, the combing head 1 is not limited to a rectangular parallelepiped shape, and may be, for example, a cylinder perpendicular to the axis of the handle. Accordingly, the lamp tube 30 may be installed on the combing head 1 along the diameter direction or in a direction parallel to the diameter.

[0065] It can be understood that the lamp tube 30 can be installed on both sides of the comb housing, in the diameter direction, in the axial direction or in other suitable positions.

[0066] The photothermal air comb 100 of the present application has the following advantages:

[0067] 1) Low power consumption and high efficiency: Due to the dual energy sources (light energy + heat energy) of the tungsten or carbon filament light source, the heat source (using a tungsten or carbon filament light source tube 30) can be infinitely close to the hair. Its temperature is lower than that of traditional hair dryers, eliminating the heat and power loss caused by the distance between traditional hair dryers and hair, achieving the dual beneficial effects of low power consumption and high efficiency hair drying.

[0068] 2) Portability: With the dual beneficial effects of reduced power consumption and improved efficiency, the product can be designed with wireless batteries, greatly increasing the convenience and storage of the product during use;

[0069] 3) Hair protection: Due to the effect of near-infrared light energy generated by tungsten or carbon filament light sources, the external heat energy required for hair moisture evaporation is greatly reduced; it avoids the loss of nutrients from the hair scales and medulla due to high temperature, and effectively protects the hair structure.

[0070] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of protection of the present application is defined by the appended claims and their equivalents.
