Description

TECHNICAL FIELD

[0001] The present invention relates to the technical field of hair care appliances, and in particular to a photothermal hair dryer with a brush. BACKGROUND ART

[0002] The hair drying principle of conventional hair dryers is as follows: cold air is drawn in by a fan and blown out from the air outlet of the fan, the cold air is heated by a high-power heating element, and then the heated air is rapidly blown onto the hair through the air outlet. Thereby, the moisture in the hair is evaporated by heating, or the moisture is removed by the high-speed flowing warm air, achieving the purpose of drying the hair. However, conventional hair dryers have high output and high power consumption, the temperature of the heating wires or heating plates is high, and the risk of skin burns and hair damage during use increases. The higher the output of a hair dryer, the higher its temperature, and the more likely it is to damage the hair and scalp. When hair is wet, its outer layer structure, the hair cuticle, is in an open state (the hair cuticle serves to protect the nutrients inside the hair). When the hair cuticle is open, high temperature directly acts on the hair fibers and hair medulla, rapidly evaporating the moisture in the hair medulla (the hair medulla affects the gloss and color depth of the hair, and high temperature will cause the dye therein to change), making the hair lose luster, turn yellow, and develop split ends. The higher the output of a hair dryer, the higher its temperature. When warm air acts on the hair rapidly, the requirement for the rotational speed of the fan also increases, which is accompanied by higher noise and increased cost. In order to meet the high-power heating and high-speed fan output requirements, the device cannot be powered wirelessly, which increases the trouble of storage and greatly reduces the convenience of use.

[0003] Hair dryers with hot air brushes are an improved version of hair dryers. Such hair care products not only dry hair but also comb it and massage the scalp. Therefore, hair dryers with hot air brushes are becoming an essential item for beautiful hair. However, in conventional hot air brush hair dryers, the comb section is attached to the body by a tight fit and heat crimping. This tight fit requires high tolerance precision in the manufacturing of the comb section and the body, making relative rotation between the comb section and the body difficult to control. Furthermore, the heat crimping process is inefficient and cumbersome. Conventional hot air brush hair dryers use an infrared lamp tube installed in the body for sterilization, but the light emitted to the comb section diffuses too much, resulting in ineffective sterilization. Additionally, conventional hot air brush hair dryers have a complex structure, making them inconvenient to carry. [Overview of the Initiative] [Problems that the invention aims to solve]

[0004] The objective of the present invention is to provide a light-heating hair dryer with a brush that has low power consumption, high efficiency, hair care functions, and is suitable for portability. [Means for solving the problem]

[0005] To achieve the above objectives, the present invention employs the following technical solutions.

[0006] A light-powered hair dryer with a brush includes a housing, a main control board located inside or mounted in the housing, and a fan electrically connected to the main control board. The light-powered hair dryer with a brush also includes a comb and a handle. The housing is divided accordingly into a comb housing and a handle housing. One or more lamp tubes electrically connected to the main control board are mounted inside the comb housing. The lamp tubes are tungsten filament lamp tubes and / or carbon filament lamp tubes. The light waves emitted from the lamp tubes include near-infrared light. The comb housing is provided with a set of comb teeth for separating and hanging down hair to form a hair area. The comb housing is provided with one or more ventilation passages. The fan, the outside of the lamp tubes, and the ventilation passages are in airflow communication. During use, the ventilation passages are in airflow communication with the hair area. During use, a fan directs cold air into the lamp tube, where it is heated into warm air. This warm air then either dries the hair through the hair area using hot air, or blows away moisture from the hair surface before flowing into the ventilation passage. Near-infrared light emitted from the lamp tube is irradiated onto the hair area at close range to assist in hair drying with near-infrared light.

[0007] Furthermore, a battery electrically connected to the main control board is installed in the internal cavity of the housing. The light from the lamp tube includes near-infrared light of 900-2500 nm for irradiating hair at close range. The entire photothermal brush hair dryer has the shape of a straight rod, with the comb part located at the front end of the straight rod and the handle located at the rear end of the straight rod.

[0008] In some embodiments, the main control board and battery are mounted inside the handle. The fan is mounted inside the handle or comb. The fan includes a fan housing and rotating blades inside the fan housing. The fan housing is formed as a vent, or vents are formed at both ends of the fan. The vents communicate with the inside of the fan housing as the fan's intake and exhaust ports, forming the fan's airflow path. The fan's airflow path communicates with the outside of the lamp tube surface and the vent passage.

[0009] In some embodiments, the comb housing is provided with one or more lamp tube sockets. One lamp tube is installed in each lamp tube socket. Each lamp tube socket has a side opening. The side openings of the lamp tube sockets serve as ventilation openings and light emission openings for the lamp tubes. During use, the thermal energy of the light-emitting field of the lamp tube heats the cold air flowing through the lamp tube to form warm air, which is blown from the side opening of the lamp tube socket onto the hair area, passes through the hair area, and then flows into the ventilation passage, and the light emitted from the lamp tube irradiates the hair area through the side opening.

[0010] In some embodiments, the side opening of the lamp tube socket is positioned longitudinally along the lamp tube and conforms to the length of the ventilation passage. The lamp tube socket or side opening is positioned parallel to the ventilation passage. Two of the lamp tube sockets are installed in the comb housing. One or more ventilation passages are formed between the two lamp tube sockets in the comb housing. The lamp tube sockets or the lamp tubes are parallel to each other.

[0011] In some embodiments, the ventilation passage is an inclined groove that slopes toward the lamp tube, facilitating the smooth flow of air heated by the lamp tube into the ventilation passage after passing through the hair area.

[0012] In some embodiments, the fan is mounted inside the handle. The handle housing is provided with an air intake. One of the fan's vents is located at the air intake of the handle housing. The fan is mounted coaxially inside the handle housing. During use, the fan draws ambient air into the fan through the air intake of the handle housing and the fan's vent, flows through the other vent of the fan to the lamp tube where it is heated into hot air, blows onto the hair area, flows through the hair area into the ventilation passage, and then flows out of the ventilation passage to the outside environment.

[0013] In some embodiments, the fan is mounted inside the comb housing. The fan's intake port is located outside the ventilation passage and communicates with it for airflow. The fan's outlet port communicates with the outside of the lamp tube for airflow. During use, ambient air is drawn in from the hair area through the ventilation passage and the fan's intake port into the fan, exhausted from the fan's outlet, flows into the lamp tube where it is heated by the warm air, blown onto the hair area, passes through the hair area, flows back into the ventilation passage, and is re-inhaled into the fan from the ventilation passage and the fan's intake port to complete one cycle. In this cycle, the air repeatedly flows into the lamp tube, is heated, and acts on the hair area.

[0014] In some embodiments, an air guide cover is installed in the comb housing. The air guide cover is fitted over the fan and lamp tube. The air guide cover directs the air flowing out from the fan outlet to the lamp tube.

[0015] In some embodiments, the comb housing is provided with a ventilation assist port. The ventilation assist port allows airflow from the external environment to the fan's intake port. During use, the fan draws ambient cool air into the fan through the ventilation assist port and the fan's intake port. The fan is mounted perpendicular to the axial direction of the light-heating brush hair dryer. [Effects of the Invention]

[0016] The beneficial effects of this invention are as follows:

[0017] The present invention's light-heat brush-equipped hair dryer boasts low power consumption and high efficiency. Through the effect of dual energy sources (light energy and thermal energy), the heat source can be brought extremely close to the hair, resulting in a lower temperature compared to conventional hair dryers. This avoids the heat energy and power consumption caused by distance between the hair dryer and the hair, achieving the dual beneficial effects of low power consumption and high efficiency in drying hair. The present invention's light-heat brush-equipped hair dryer is also portable, and the dual beneficial effects of power reduction and improved efficiency allow for a wireless battery design, significantly improving convenience during use and storage. Furthermore, the present invention's light-heat brush-equipped hair dryer has a hair care function. Through the effect of near-infrared light energy, it significantly reduces the external heat energy required for the evaporation of moisture from the hair, avoiding the loss of nutrients in the hair cuticle and medulla due to high temperatures, and effectively protecting the hair structure.

[0019] Hereinafter, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. On the contrary, the provision of these embodiments is for the purpose of enabling a more thorough understanding of the present invention, and can fully convey the scope of the present invention to those skilled in the art.

[0020] The terms used in this specification are for the purpose of describing specific exemplary embodiments only, and are not intended to be limiting. As used in this specification, the singular forms "a", "an" and "the" may be intended to include the plural forms as well, unless the context clearly indicates otherwise. The terms "comprise", "comprising", "include" and "have" are inclusive, and thus specify the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or groups thereof.

[0024] Referring to Figures 1 to 12, the present invention relates to a photovoltaic hair dryer with a brush 100. The photovoltaic hair dryer with a brush 100 is an overall straight rod in shape, consisting of a comb section 1 and a handle 10, and includes a housing, a main control board 20 mounted in the internal cavity of the housing, a lamp tube 30 electrically connected to the main control board 20, a fan 40, and a battery 50. The housing is divided accordingly into a comb section housing and a handle housing. The housing is provided with a through hole 14 for mounting a power supply interface 21. The charging interface 21 is installed on the main control board 20 or electrically connected to the main control board 20. The power supply interface 21 is connected to an external power source through the through hole in the housing to charge the battery 50 and supply power to the main control board 20. The photovoltaic hair dryer with a brush 100 further includes a set of buttons (not shown) electrically connected to the main control board 20 for operating the photovoltaic hair dryer with a brush 100 and setting its functions. A lamp tube socket 15 is installed in the comb section 1. A lamp tube 30 is installed inside the lamp tube socket. A pair of comb teeth 13 for separating hair into smaller sections is further installed in the comb section 1. The hair hangs down within the comb teeth or the spaces between the comb teeth, forming a hair area. Air can pass through the gaps in the hair. One side of the lamp tube socket facing the comb teeth is set up as an opening 150, which is an air vent and a light outlet. The warm air heated by the lamp tube 30 is blown through the opening 150 onto the hair area of ​​the comb teeth and passes through the gaps in the hair. The light emitted from the lamp tube 30 irradiates the hair area through the opening 150. The lamp tube 30 is a tungsten filament lamp tube or a carbon fiber lamp tube, and there is at least one lamp tube. The hair is dried by the thermal and light energy of the lamp tube 30. The pair of comb teeth 13 may be arranged in multiple rows. There are gaps between the multiple rows of comb teeth. The spacing between the comb teeth includes the spacing between adjacent comb teeth and the spacing between two adjacent rows of comb teeth. Light from the lamp tube 30 is emitted from the side opening 150 of the lamp tube socket 15 and irradiates the hair area to dry the hair, and hot air flowing out from the side opening 150 inside the lamp tube socket 15 blows onto the hair area to dry the hair. A ventilation passage 11 is provided in the comb housing.The ventilation passage 11 corresponds to the spacing between the teeth of each row of combs, and is connected to the lamp tube socket 15 by the opening 150, the spacing between the teeth, and the hair-like area of ​​the teeth.

[0025] A tungsten filament lamp tube or carbon fiber lamp tube 30 uses a tungsten filament or carbon fiber as the filament, i.e., the light-emitting material. The filament is installed inside a transparent lamp cover and emits light after power is applied. Oxidation of the filament due to high temperatures is prevented by maintaining a vacuum inside the lamp cover or by filling it with a low-pressure inert gas or halogen gas. When a halogen gas such as iodine or bromine is filled inside the transparent lamp cover of a tungsten filament lamp tube or carbon fiber lamp tube, a halogen lamp (also called a tungsten halogen lamp) is obtained. A tungsten filament lamp tube or carbon fiber lamp tube belongs to the category of incandescent light bulb lamp tubes and is realized by the structure of an incandescent light bulb. When a tungsten filament and / or carbon fiber is used as the light-emitting material, i.e., the filament, the life of the lamp tube can be extended by filling the transparent lamp cover with a certain ratio of inert gas or halogen gas, and the spectral distribution of the tungsten filament and / or carbon fiber lamp tube can be changed by adjusting the air pressure inside the lamp, the gas ratio, the current pulse, the supply voltage, etc. Preferably, a halogen lamp tube is used as the carbon-tungsten filament lamp tube and / or carbon filament lamp tube 30 of the light-heating brush-equipped hair dryer 100 of the present invention.

[0026] The thermal energy generated by the tungsten filament lamp tube or carbon fiber lamp tube 30 can heat the cold air drawn in by the fan 40 into hot air. The hot air plays a role in drying the hair by evaporating or removing moisture when blown onto it. In addition, the near-infrared light of 900-2500 nm contained in the light from the tungsten filament lamp tube or carbon fiber lamp tube 30 is absorbed by water molecules, generating high-frequency vibrations that produce internal heat and evaporate the water. This near-infrared light wave irradiates damp hair, causing the water molecules on the surface of the hair to generate internal heat and evaporate, thus assisting in drying the hair.

[0027] In the light-heating brush-equipped hair dryer 100 of the present invention, one or more tungsten filament lamp tubes or carbon fiber lamp tubes 30 are attached to the comb section 1. Specifically, a lamp tube socket 15 is installed in the comb section housing, and the lamp tube 30 is installed inside the lamp tube socket 15. The side of the lamp tube socket 15 is set up as an opening 150 along the longitudinal direction of the lamp tube. The opening 150 communicates airflow between the comb teeth 13 and the hair area, and also irradiates the hair area on the comb teeth with light emitted from the lamp tube 30 inside the lamp tube socket 15. The opening 150 functions as a vent and is also used as a light emission port for the lamp tube 30, emitting light from the tungsten filament lamp tube or carbon fiber lamp tube 30 from the opening 150 to irradiate the hair area at close range. The principle for setting up the lamp tube 30 is that the lamp tube 30 can come very close to the hair when drying the hair. Multiple tungsten filament lamp tubes and / or carbon filament lamp tubes 30 are attached to the comb section 1, and multiple lamp tube sockets 15 are provided, with one lamp tube 30 attached to each lamp tube socket 15. The side walls of each lamp tube socket 15 are provided as openings 150 along the longitudinal direction. The openings 150 may take various forms, such as long grooves, open shapes, or a set of through holes.

[0028] The main control board 20 and battery 50 are mounted inside the handle 10 (handle housing). A partition plate 17 may be installed inside the handle housing to isolate the main control board 20 and battery 50 from the fan 40, and to seal and protect the main control board 20 and battery 50.

[0029] The fan 40 may be mounted within the handle 10 or within the comb portion 1. The fan 40 includes a housing and rotating blades within the housing. Both ends of the fan housing (i.e., the upper and lower ends along the direction of the fan's rotation axis) are vents 42, 43, which serve as the fan's intake and exhaust ports, communicating with the internal cavity of the fan housing to form the fan's airflow path. In other embodiments, the vents 42, 43 are also located on the sides of the fan housing.

[0030] In some embodiments, the housing of the light-powered brush-type hair dryer 100 may be further equipped with ventilation holes 12. The ventilation holes 12 may be installed in the comb housing or the handle housing. Outside air flows into the light-powered brush-type hair dryer 100 through the ventilation holes 12. In this case, the ventilation holes 12 may serve as an air intake, and the ventilation passage 11 installed in the comb housing may serve as an air outlet. In other embodiments, the ventilation holes 12 may not be installed. In this case, the ventilation passage 11 may serve as a circulating air intake and outlet.

[0031] The battery 50 may be a rechargeable battery or a removable and replaceable disposable battery. The power interface 21 may be connected to an external power source to directly power the light-heating brush hair dryer 100 or to charge the battery 50.

[0032] In some embodiments, one end of the lamp tube socket 15 is formed as an air intake 151, which communicates with the airflow path of the fan 40. The lamp tube socket 15, with its air intake 151 and side opening 150, communicates with the airflow path of the fan 40, the spacing of the comb teeth, and the hair area of ​​the comb teeth. The air intake 151 and opening 150 of the lamp tube socket 15 may be ventilation holes located in different positions or may be used in common, for example, the opening 150 may function as both an intake and an exhaust. The ventilation holes 12, fan 40, lamp tube socket 15 (space outside the lamp tube), the spacing of the comb teeth, the hair area of ​​the comb teeth, and the ventilation passage 11 are connected to a gas passage to form the hair drying airflow path 200 of the photothermal brush hair dryer 100. In other embodiments, a circulating gas path is formed between the spacing of the comb teeth, the hair area of ​​the comb teeth, the ventilation passage 11, the air passage of the fan 40, and the lamp tube socket 15, serving as the hair drying airflow path 200 of the photothermal brush hair dryer 100. The hair on the comb teeth is dried by the hot air flowing out from the side opening 150 of the lamp tube socket 15, and light from the lamp tube socket 15 irradiates the hair area from the side opening 150 of the lamp tube socket, assisting in the drying of the hair by light irradiation. The arrows in Figures 4 to 6 and Figures 10 to 11 represent the airflow path 200. The arrows in Figure 7 show the case where light from the light source (lamp tube 30) irradiates the hair area.

[0033] Referring to Figures 1 to 7, the first embodiment of the present invention, a light-heating brush-equipped hair dryer 100, includes a comb section 1 and a handle 10, and the entire structure is a straight rod. Its housing is formed by assembling an upper housing 101 and a lower housing 102, and is divided accordingly into a comb section housing and a handle housing. The handle is cylindrical, but not limited to a cylindrical shape. The comb section is rectangular, but not limited to a rectangular parallelepiped. Accordingly, the parts of the upper housing 101 and lower housing 102 corresponding to the handle are semi-cylindrical (not limited to semi-cylindrical) separated along the longitudinal direction, and the parts of the upper housing 101 and lower housing 102 corresponding to the comb section are rectangular parallelepiped (not limited to rectangular parallelepiped). The comb section 1 is fitted with three rows of comb teeth 13 for separating hair into smaller sections (not limited to three rows). The hair hangs down within the comb teeth or the spaces between the comb teeth, forming a hair area, and air passes through the gaps in the hair within the hair area.

[0034] The housing in the comb-shaped portion of the upper housing 101 is an annular housing. Both sides (in the longitudinal direction) of the comb-shaped portion of the lower housing 102 are formed as lamp tube sockets 15, which are two opening grooves. The upper housing 101 covers the tops of the opening grooves when the lower housing 102 is placed over it. One lamp tube 30 is installed inside each of the two lamp tube sockets 15. On the side of the lamp tube socket 15, an opening 150 is formed in the longitudinal direction of the lamp tube 30, which serves as the light output port of the lamp tube 30 and the outlet port of the lamp tube socket 15. In the intermediate housing in the comb-shaped portion of the lower housing 102, two through grooves are opened along the longitudinal direction to form a ventilation passage 11, which communicates with the side openings 150 of the lamp tube socket through the spacing of the comb teeth and the hair-like area of ​​the comb teeth. When the upper housing 101 is engaged with the lower housing 102 and assembled, a rectangular (but not limited to rectangular) comb housing is formed in the comb portion accordingly, and two lamp tube sockets 15 are installed parallel to each other along the longitudinal direction within the comb housing. Three rows of comb teeth 13 are installed on the bottom surface of the comb portion of the lower housing 102, with the outer two rows of comb teeth inclined outwards. Two through grooves are formed between two adjacent rows of comb teeth 13 to form a ventilation passage 11. The ventilation passage 11 is an inclined groove that slopes toward the side opening 150 of the lamp tube socket 15. As a result, the airflow inside the lamp tube socket 15 is blown out from the opening 150, passes through the gaps between the comb teeth and the hair area of ​​the comb teeth, and then flows smoothly into the ventilation passage 11 and is blown out through the ventilation passage 11. In this embodiment, the airflow blown out from the ventilation passage 11 is blown out of the comb portion upward (towards the side away from the comb teeth). Refer to Figure 6, where the arrow lines represent the light emission area. Because a low-power carbon-tungsten filament lamp tube and / or carbon filament lamp tube 30 are used, during use, the lamp tube 30 comes into very close contact with the hair on the comb teeth, the thermal energy of the lamp tube heats the airflow and blows it onto the hair area, and the near-infrared light contained in the light from the light source irradiates the hair at close range, thereby suppressing the problem of hair damage that occurs when drying hair with a high-power photothermal hair dryer and achieving efficient hair drying.

[0035] After the upper housing 101 and lower housing 102 are assembled, a cylindrical handle housing is formed corresponding to the handle portion, a vibration-reducing ring sleeve 41 is fitted to the outside of the fan 40 and mounted inside the handle housing, and the fan 40 is mounted coaxially inside the handle housing. The fan vent 42 communicates with the airflow to the ventilation hole 12 of the light-type brush hair dryer 100. Referring to Figure 5, the fan vent 42 is located at the ventilation hole 12 of the light-type brush hair dryer 100. When ambient cool air is drawn into the housing from the ventilation hole 12, it is drawn into the fan's air passage from the fan vent 42 and exhausted from another fan vent 43. The fan vent 43 is located in the air guide passage 16 formed inside the housing at the connection point between the comb portion 1 and the handle 10, and communicates with the airflow. The air guide passage 16 formed within the housing at the connection point between the comb section 1 and the handle 10 communicates airflow to the lamp tube socket 15. The size of the fan 40 is adapted to the size of the cavity within the housing of the light-heating brush hair dryer 100, specifically to the cavity of the handle housing, and is coaxially mounted within the handle 10 along the axial (or length) direction of the light-heating brush hair dryer 100.

[0036] The main control board 20 and the battery 50 are mounted at the rear of the handle housing. A partition plate 17 is installed on one side of the ventilation hole 12 (facing the fan 40). Another partition plate 17 is installed inside the handle housing, close to the rear end. The main control board 20 and the battery 50 are mounted inside the handle housing by the two partition plates 17 and isolated from the fan 40 and the comb section 1.

[0037] Refer to Figures 4 to 6 together, where the arrows in the figures represent airflow paths. The hair drying airflow path 200 of the light-heat brush-equipped hair dryer 100 according to this embodiment is as follows: Ambient air (cold air) is drawn in through the ventilation hole 12 by the intake / exhaust of the fan 40, drawn into the fan 40 through the fan ventilation port 42, flows into the lamp tube socket 15 through the air guide passage 16 via another ventilation port 43 of the fan, and enters the lamp tube socket 15 through the intake port 151 of the lamp tube socket 15, where it is heated by the thermal energy generated in the lamp tube 30 to form hot air. The hot air flows out from the opening 150 of the lamp tube socket 15 and acts on the hair area of ​​the comb teeth, and after passing through the gaps between the comb teeth 13 and the hair area of ​​the comb teeth, it flows out from the slanted ventilation passage 11, and dries the hair with hot air as it passes through the hair area. In the hair drying airflow path 200 of this embodiment, air is drawn in at the handle and flows into the comb section 1 in the longitudinal direction of the handle.

[0038] Refer to Figure 7 as well; the arrow lines indicate the direction of light irradiation. The intermediate region corresponding to the two arrow lines from the lamp tube 30 in the figure represents the range of light irradiation. The light emitted from the lamp tube 30 irradiates the hair area of ​​the comb teeth 13 through the side opening 150 of the lamp tube socket 15, assisting in hair drying with near-infrared light.

[0039] The hair drying principle of the light-heating brush-equipped hair dryer 100 according to this embodiment is as follows.

[0040] 1) Near-infrared light effect: Near-infrared light in the 900-2500 nm range is absorbed by water molecules, generating high-frequency vibrations that produce internal heat and evaporate the water. By using a tungsten filament lamp tube or a carbon fiber lamp tube (e.g., a halogen lamp tube) 30 and irradiating damp hair with near-infrared light waves emitted from these, the light waves and water molecules on the surface of the hair generate internal heat, evaporating the moisture on the hair surface and achieving the effect of assisting in hair drying.

[0041] 2) Thermal energy effect: Cold air is drawn in by the fan 40 and flows through the fan vent into the lamp socket 15, which is the space outside the tungsten filament lamp tube or carbon fiber lamp tube (e.g., halogen lamp tube) 30. Due to the thermal energy effect of the light field of the tungsten filament lamp tube or carbon fiber lamp tube (e.g., halogen lamp tube) 30, the flowing cold air is heated into warm air before flowing into the hair area to perform hot air drying and remove moisture, and the comb teeth separate the hair into smaller sections, which facilitates an increase in the contact area between the warm air and the hair and an increase in the flow velocity of the warm air. After passing through the hair area, the warm air flows out from the ventilation passage 11.

[0042] Referring to Figures 8 to 12, the light-heating brush-equipped hair dryer 100 according to the second embodiment of the present invention includes a comb section 1 and a handle 10, and the entire structure is a straight rod. Its housing is formed by assembling an upper housing 101 and a lower housing 102, and is divided accordingly into a comb section housing and a handle housing. The handle is cylindrical, but is not limited to a cylindrical shape. The comb section is rectangular, but is not limited to a rectangular parallelepiped. Accordingly, the parts of the upper housing 101 and the lower housing 102 corresponding to the handle are semi-cylindrical, divided along the longitudinal direction, and the part corresponding to the comb section 1 is rectangular. The comb section 1 is fitted with three rows of comb teeth 13 for separating hair into smaller sections (not limited to three rows). The comb teeth are spaced apart. Hair hangs down within the comb teeth or the spaces between the comb teeth, forming a hair area, and air passes through the gaps in the hair. A ventilation passage 11 is provided in the comb section 1. The ventilation passage 11 corresponds to the spacing between the comb teeth in each row, and is connected to the lamp tube socket 15 by the opening 150, the spacing between the comb teeth, and the hair area.

[0043] The interior of the housing in the comb-shaped portion of the upper housing 101 is formed as a cavity. A fan bracket 19 is installed at the bottom of the cavity. The fan 40 is attached to the fan bracket 19. An air guide cover 103 is installed at the top of the cavity. When the air guide cover 103 covers the top of the upper housing 101, it seals the fan 40 within the cavity of the upper housing 101. The air guide cover 103 fits the comb-shaped housing, i.e., the housing in the comb-shaped portion of the upper housing 101. When the upper housing 101 is positioned horizontally according to the orientation shown in the figure, the fan 40 is mounted vertically, i.e., the fan 40 is mounted perpendicular to the axial (length) direction of the light-heating brush hair dryer 100. The interior of the air guide cover 103 is formed as an air guide passage, circulating the airflow between the fan 40's vent and the lamp tube socket 150.

[0044] In the lower housing 102, two opening grooves are formed on both sides (in the longitudinal direction) of the comb-shaped portion, serving as lamp tube sockets 15. One lamp tube 30 is installed in each lamp tube socket 15. After the air guide cover 103, upper housing 101, and lower housing 102 are assembled, the lamp tube sockets 15 (i.e., the space outside the lamp tubes 30) are connected to the cavity in the upper housing 101 and the interior of the air guide cover 103. On the side of the lamp tube socket 15, an opening 150 is formed along the longitudinal direction of the lamp tube, serving as the light output port of the lamp tube 30 and the ventilation port of the lamp tube socket 15. In the intermediate housing located in the comb-shaped portion of the lower housing 102, two through grooves are opened along the longitudinal direction to form a ventilation passage 11, which connects to the gas passage to the side opening 150 of the lamp tube socket and to the air passage of the fan 40 through the spacing of the comb teeth and the hair area of ​​the comb teeth. When the upper housing 101 and the lower housing 102 are assembled, the comb portion is formed accordingly as a comb housing in the shape of a rectangular parallelepiped (but not limited to a rectangular parallelepiped), and two lamp tube sockets 15 are installed parallel to each other along the longitudinal direction within the comb housing. On the bottom surface of the comb portion of the lower housing 102, three rows of comb teeth 13 are installed, with the two outer rows of comb teeth 13 inclined outwards. Two through grooves are provided between two adjacent rows of comb teeth 13 to form a ventilation passage 11. Each row of comb teeth contains multiple teeth. The spacing of the comb teeth and the hair area of ​​the comb teeth communicate with airflow to the ventilation passage 11 and to the opening 150 in the side wall of the lamp tube socket. The ventilation passage 11 is an inclined groove that slopes toward the side opening 150 of the lamp tube socket 15. As a result, the airflow inside the lamp socket 15 is blown out from the opening 150 and flows smoothly through the gaps between the comb teeth and the hair area (where air passes through the gaps between the hairs) into the ventilation passage 11. It then flows through the ventilation passage 11 and the fan's vent 43 into the fan 40, and out through another vent 42 of the fan 40, where it is guided to the surface of the lamp tube 30 inside the lamp socket 15 by the air guide passage in the air guide cover 103. The hot airflow flows back into the ventilation passage 11 from the outlet 150, passing through the gaps between the comb teeth and the hair area again, thus circulating and drying the hair area of ​​the comb teeth.In this embodiment, when the upper housing 101 and the lower housing 102 are assembled, a gap is formed in the comb section as a ventilation assist opening 18, and cold air from the outside is drawn into the air passage of the fan 40 from the ventilation assist opening 18. When the fan 40 is operating, it simultaneously draws in cold air from the outside through the ventilation assist opening 18 and the gap between the comb teeth / hair area. In this embodiment, the hair drying airflow circulates only within the comb section, and there is no airflow within the handle section, with the gas passage being blocked between the inside of the comb section housing and the inside of the handle housing by the housing side wall. Exemplarily, a partition plate 17 is installed inside the rear part of the comb section of the upper housing 102 to further block the airflow within the comb section 1 and the handle 10, and to protect the main control board 20 and the battery 50.

[0045] After the upper housing 101 and lower housing 102 are assembled, a cylindrical handle housing is formed corresponding to the handle portion. The main control board 20 and battery 50 are mounted in the handle housing. A partition plate 17 is installed inside the handle housing, allowing the main control board and battery to be mounted inside the handle. A through hole 14 is provided in the handle housing. The charging interface 21 is electrically connected to an external power source via the through hole 14.

[0046] Refer to Figures 10-11, where the arrows represent the hair drying airflow path 200. The fan 40 draws in cold air from the gaps between the comb teeth and the hair area of ​​the comb teeth, enters the fan 40 through the ventilation passage 11, flows through the fan vent 42 to the two lamp tubes 30, and after the cold air flowing over the surface of the lamp tubes 30 (i.e., inside the lamp tube socket 150) is heated into warm air by the thermal energy effect of the light field of the lamp tubes 30 (tungsten filament or carbon filament light source, e.g., halogen lamp light source), the warm air flows over the hair area, completing one circulation and moving on to the next circulation. After flowing over the hair area, the warm air flows out of the ventilation passage 11 and is re-drawn into the fan 40, flows through the fan vent 42 to the two lamp tubes 30, and is heated a second time to form warm air. After flowing over the hair area again, the warm air flows out of the ventilation passage 11 and moves on to the next internal circulation. By repeating this circulation, the heating time of the flowing air is shortened, the heat energy is more stable, and more water molecules are blown away.

[0047] Specifically, the fan 40 draws in cold air from the outside through the gaps inside the hair area of ​​the comb teeth and the gaps within the comb teeth. The cold air is drawn into the fan 40 via the ventilation passage 11 and the fan vent 43, and guided into the lamp tube socket 15 from the flow guide cover 103 via the fan vent 42. After the cold air flowing over the surface of the lamp tube 30 is heated by the thermal energy effect of the light field of the lamp tube 30 (tungsten filament or carbon filament light source, e.g., halogen lamp light source), it flows into the hair area from the side opening 150 of the lamp tube socket 15, where it is separated into smaller pieces by the comb teeth 13, facilitating an increase in the contact area between the warm air and the hair and an improvement in the flow velocity of the warm air. After flowing through the hair area, the warm air flows out through the ventilation passage 11, is re-inhaled by the fan 40 via the fan vent 43 (in this case, the airflow in the first circulation is slightly higher than the initial ambient airflow temperature), flows through the fan vent 42 to the tungsten filament or carbon filament light source lamp tube 30, and is heated a second time, forming warm air. The warm air flows through the hair area again (in this case, the hair has less surface moisture due to near-infrared light than in the first circulation, and the external thermal energy required for the hair decreases accordingly), then flows out through the ventilation passage 11 and moves to the next internal circulation (by repeating this circulation, the heating time of the flowing air is shortened, the heat stability is excellent, and more water molecules are blown away).

[0048] The light-heating brush-equipped hair dryer 100 according to this embodiment is equipped with a hair drying assist airflow path. Referring to Figure 10, the fan 40 draws in cool air from the outside through the ventilation assist port 18 of the comb housing, and draws it into the fan 40 via the ventilation passage 11, where it participates in hair drying through the airflow circulation described above.

[0049] The hair drying principle of the light-heating brush-equipped hair dryer 100 according to this embodiment is as follows.

[0050] 1) Near-infrared light effect: Near-infrared light in the 900-2500 nm range is absorbed by water molecules, generating high-frequency vibrations that produce internal heat and evaporate the water. By using a lamp tube 30 with a tungsten filament or carbon filament light source and irradiating damp hair with its near-infrared light waves, the light waves and water molecules on the surface of the hair generate internal heat, evaporating the moisture on the hair surface. The light from the light source is then irradiated onto the hair hanging from the comb teeth through the side opening 15 of the lamp tube socket 15, achieving the effect of assisting in hair drying.

[0051] 2) Thermal energy effect: Cold air is drawn in by the fan 40, flows through the fan vent 4 to the lamp tube (tungsten filament or carbon filament light source) 30, and the thermal energy effect of the light field of the lamp tube 30 heats the flowing cold air into warm air before it flows into the hair area. At the same time, the comb teeth divide the hair into smaller sections, which facilitates an increase in the contact area between the warm air and the hair and an improvement in the flow velocity of the warm air. After flowing through the hair area, the warm air flows out through the ventilation passage 11 (as a circulation outlet), is re-drawn into the fan through the fan vent, flows through the fan vent to the tungsten filament or carbon filament light source, is heated a second time, forms warm air, and flows through the hair area again. Repeating this circulation shortens the heating time of the flowing air, improves the stability of the heat, and blows away more moisture.

[0052] 3) Air intake and circulation effect: In conventional hair dryers, the head floats at a certain distance from the user during use. As a result, some of the warm air is lost into the surrounding space due to heat dissipation by the airflow during blow-drying, preventing it from effectively acting on the hair. Furthermore, it is necessary to constantly draw in cool air from the surroundings during hair drying, heat it with a heating element, and then radiate it to the hair. This increases the energy consumption of the product due to heat loss and the continuous introduction of cool air, reducing the efficiency of hair drying.

[0053] On the other hand, in this embodiment, the effectiveness of hair drying is improved by circulating air heating. The beneficial effects of the heating cycle are as follows: In the latter half of the hair drying process, the moisture content of the hair decreases, the hair is drying, and less heat is consumed when the hot air acts on the hair. Therefore, the power consumption required in the latter half of the hair drying process is reduced, the heat retention rate is high, and the heating time is short, so the utilization rate of thermal energy is effectively improved and waste of thermal energy is reduced.

[0054] In each of the above embodiments, the comb portion 1 is not limited to a rectangular parallelepiped shape, but may be, for example, a cylindrical body perpendicular to the handle axis. Accordingly, the lamp tube 30 may be attached to the comb portion 1 in the diametrical direction or in a direction parallel to the diameter.

[0055] The lamp tube 30 may be mounted on both sides of the comb housing, in the diametrical direction, axial direction, or at other suitable positions.

[0056] The light-heating brush-equipped hair dryer 100 according to the present invention has the following advantages.

[0057] 1) Low power consumption, high efficiency: Due to the effect of dual energy sources (light energy and thermal energy), which are tungsten filament light sources or carbon filament light sources, the thermal energy (tungsten filament or carbon filament light source lamp 30) comes very close to the hair, resulting in a lower temperature compared to conventional hair dryers. This avoids the consumption of thermal energy and power caused by the distance between the conventional hair dryer and the hair, achieving the dual beneficial effect of drying hair with low power consumption and high efficiency.

[0058] 2) Portability: The dual beneficial effects of power reduction and efficiency improvement enable a wireless battery design for the product, significantly improving convenience during use and storage.

[0059] 3) Hair care benefits: The near-infrared light energy generated by the tungsten or carbon filament light source significantly reduces the external heat energy required for the evaporation of moisture from the hair, preventing the loss of nutrients from the hair cuticle and medulla due to high temperatures, and effectively protecting the hair structure.

[0060] Although embodiments of the present invention have been illustrated and described, those skilled in the art will understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, but the scope of protection of the present invention is limited by the appended claims and their equivalents.
