Description

Technical Field

[0001] This utility model belongs to the field of hair dryer technology, specifically relating to a light source device for use inside a hair dryer and a light-powered hair dryer having the same. Background Technology

[0002] A hair dryer uses an electric motor to drive a rotor that rotates the fan blades. As the blades rotate, air is drawn in through the air inlet, and the resulting centrifugal airflow is then blown out through the nozzle. If the heating element on the heating bracket in the nozzle is energized and heated, hot air is blown out; if the switch prevents the heating element from heating, cold air is blown out. This is how a hair dryer achieves drying and reshaping purposes.

[0003] In recent years, with the rapid development of photoelectric technology, photoelectric hair dryers, as a new type of product combining phototherapy and rapid hair drying functions, have gradually entered the market and have received widespread attention from consumers. These hair dryers integrate a light source device (such as an LED array) inside the body, and a heating element around the light source device to heat the airflow. This allows them to release specific wavelengths of light, such as infrared or visible light, while drying hair, to promote scalp blood circulation, accelerate hair moisture evaporation, and nourish the hair. However, the light source device in hair dryers generally lacks ventilation and heat dissipation structures, releasing a large amount of heat during use. This heat, combined with the heat generated by the existing heating element, accumulates inside the nozzle, easily causing damage to the internal light source device over time, reducing the product's lifespan and reliability. Furthermore, the heat emitted by the light source device is not effectively utilized, increasing energy loss and waste. Utility Model Content

[0004] The purpose of this utility model is to overcome the existing technical defects and provide a light source device for use in a ventilation duct. A ventilation and heat dissipation channel is formed between the lamp holder, the light source component and the lens, which achieves the purpose of heat dissipation and cooling of the light source device during use, thereby improving the service life and reliability of the product.

[0005] Firstly, in order to solve the above-mentioned technical problems, this utility model provides a light source device for use inside a ventilation duct, comprising:

[0006] A hollow lamp holder, wherein the rear end of the lamp holder is provided with an air inlet and the front end of the lamp holder is provided with an illumination port;

[0007] A light source assembly is disposed inside the lamp holder and faces the illumination port; an air flow channel communicating with the air inlet is formed between the outer periphery of the light source assembly and the lamp holder.

[0008] A lens is disposed at the illumination port and covers the front of the light source assembly. The lens and / or the front end of the lamp holder are provided with a plurality of air outlet holes that communicate with the air flow channel.

[0009] Furthermore, the light source assembly includes a lamp holder, at least one lamp bead disposed on the lamp holder and illuminating the illumination port, and a lamp cup disposed on the lamp holder and covering the lamp bead, wherein the front end of the lamp cup abuts against the inner surface of the lens.

[0010] Furthermore, the front end of the lamp holder has a mounting platform protruding at the position corresponding to each lamp bead, and the lamp beads are inserted into the mounting platform one by one. The rear end of the lamp cup has an insertion hole through the mounting platform at the position corresponding to each lamp bead for inserting the lamp bead and the mounting platform. A circuit board is provided on the rear side of the mounting platform, and the rear end of the lamp bead passes through the mounting platform and is electrically connected to the circuit board.

[0011] Furthermore, at least one air inlet groove communicating with the air flow channel is formed between the insertion hole and the mounting platform, and several air holes communicating with the air inlet groove and the air flow channel are provided on the outer periphery of the front end of the lamp cup.

[0012] Furthermore, the mounting platform has a plurality of air inlet slots extending axially on its outer periphery, and the front end of the lamp holder has at least one protruding post with a height lower than that of the mounting platform. The front end of the protruding post abuts against the rear end face of the lamp cup, so that the air inlet slots pass through the rear end of the lamp cup and connect the inner side of the lamp cup and the air flow channel. The protruding post has a threaded hole in the middle, and the rear end of the lamp cup has a screw hole for screws to pass through at the position corresponding to each threaded hole.

[0013] Furthermore, the light source device for use inside the air duct also includes a ring sleeve fitted around the outer periphery of the lens. The inner periphery of the ring sleeve is recessed with an annular groove for the outer periphery of the lens to be inserted, and the outer periphery of the front end of the lamp cup is radially protruding with an annular platform. The outer periphery of the annular platform is inserted into the annular groove, so that the light source assembly is suspended in the lamp cup holder. The annular platform is provided with at least one through hole that runs through the front and back and communicates with the air flow channel. The lens is provided with an air outlet at the position corresponding to each through hole.

[0014] Furthermore, a ring-shaped cover is provided in the middle of the air outlet end of the air duct, which is sleeved with the front end of the lamp holder. The ring is located between the cover and the lamp holder. The inner end face of the ring abuts against the front end face of the lamp holder. A limiting part is provided on the inner circumference of the cover, which abuts against the outer end face of the ring.

[0015] Furthermore, the cavity within the lamp holder includes, from the inside back to the front, a first hole section with a uniform aperture, a flared drainage section with gradually increasing aperture, and a second hole section with a uniform aperture. The inner diameter of the second hole section is larger than that of the first hole section, and the light source assembly is disposed within the second hole section.

[0016] Furthermore, the outer side of the lens is provided with several raised spherical protrusions; the lens is made of plexiglass, and the lamp cup is made using an aluminum drawing process.

[0017] Secondly, this utility model embodiment also provides a light-powered hair dryer, including a main unit and an exhaust device disposed in the main unit. The main unit is provided with a plurality of through holes communicating with the air inlet of the exhaust device, and also includes a light source device as described in any of the first aspects, wherein the air inlet of the light source device is communicating with the air outlet of the exhaust device.

[0018] This utility model has the following beneficial effects:

[0019] 1. Firstly, the light source device forms a ventilation and heat dissipation duct between the lamp holder, the light source component, and the lens, consisting of an air inlet, an air flow channel, and an air outlet. When the light source device is installed inside the hair dryer, the air drawn in by the hair dryer can flow through this ventilation and heat dissipation duct, thereby achieving the purpose of ventilation, heat dissipation, and cooling of the inside of the light source device. This prevents the light source component inside the device from being damaged by heat during long-term use and affects its service life, thus improving the product's service life and reliability. Secondly, when the air flows through the inside of the light source device, it can be heated by the heat dissipated by the device, improving energy utilization and reducing energy loss and waste. Furthermore, the heated air and the air heated by the heating element inside the hair dryer are blown out together, improving heating efficiency and the hair drying effect.

[0020] 2. An air inlet slot is provided between the lamp cup and the mounting platform, connecting the inside of the lamp cup and the air flow channel. This allows the airflow entering the air flow channel to enter the lamp cup through the air inlet slot, directly contact the lamp beads and dissipate heat from them. The airflow entering the lamp cup flows out through the air hole at the front of the lamp cup into the air flow channel, and then blows out from the air outlet on the lens, further improving the heat dissipation effect on the light source components.

[0021] 3. Clamping the lamp cup and lens together onto the ring and then installing them into the lamp cup holder serves two purposes: first, it allows the internal light source component to be suspended in the middle of the lamp cup holder, creating an airflow channel between the light source component and the lamp cup holder; second, it allows the light source component and lens to be assembled into a stable and reliable whole, better protecting the lamp beads and lens during transportation and use.

[0022] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of the invention. Attached Figure Description

[0039] To better understand the technical content of this utility model, the following will further introduce and explain this utility model in conjunction with the accompanying drawings and specific embodiments. It should be noted that if there are descriptions such as "first" and "second" in the text, they are used to distinguish different components, etc., and do not represent the order of priority, nor do they limit "first" and "second" to be different types.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0041] Example 1

[0042] like Figures 1 to 9 As shown in the figure, the light source device 100 for use in the air duct in this embodiment includes a hollow lamp holder 1, a light source assembly 2, and a lens 3. The rear end of the lamp holder 1 is provided with an air inlet 10, and the front end of the lamp holder 1 is provided with an illumination port 11 for the light source to irradiate outwards. That is, the lamp holder 1 has a cavity that runs through the front and back. The light source assembly 2 is located in the lamp holder 1 and irradiates towards the illumination port 11. That is, the light emitted by the light source assembly 2 irradiates outwards through the illumination port 11. An air flow channel 13 communicating with the air inlet 10 is formed between the outer periphery of the light source assembly 2 and the lamp holder 1. The lens 3 is placed on the illumination port 11 and covers the front of the light source assembly 2. That is, the lens 3 is used to close the illumination port 11. The light emitted by the light source assembly needs to pass through the lens before irradiating outwards. Several air outlet holes 31 communicating with the air flow channel 16 are provided through the lens 3.

[0043] In the above structure, the light source device forms a ventilation and heat dissipation duct between the lamp holder, the light source component, and the lens, which consists of an air inlet, an air flow channel, and an air outlet. When the light source device is installed inside the hair dryer, the air drawn in by the hair dryer can flow through this ventilation and heat dissipation duct, thereby achieving the purpose of ventilation, heat dissipation, and cooling of the inside of the light source device. This prevents the light source component inside the device from being damaged by heat during long-term use and affects its service life, thus improving the product's service life and reliability. Secondly, when the air flows through the inside of the light source device, it can be heated by the heat dissipated by the device, improving energy utilization and reducing energy loss and waste. Furthermore, the heated air and the air heated by the heating element inside the hair dryer are blown out together, improving heating efficiency and hair drying effect.

[0044] Of course, in another embodiment, the air vent on the lens can be removed and replaced with several air vents that communicate with the air flow channel through the outer periphery of the front end of the lamp holder. When the light source device is applied to the middle of the air duct, the airflow is blown outward to the air outlet of the air duct. This can ensure ventilation and heat dissipation for the light source device while maintaining the integrity of the front lens, thereby improving the overall aesthetics of the product.

[0045] In one embodiment, the light source assembly 2 includes a lamp holder 21, at least one lamp bead 22 disposed on the lamp holder 21 and illuminating towards the illumination port 11, and a lamp cup 23 disposed on the lamp holder 21 and covering the lamp bead 21. The front end of the lamp cup 23 abuts against the inner side of the lens 3. That is, the lamp cup and the lens together form an illumination structure surrounding the lamp bead, so that the light emitted by the lamp bead can only pass through the lens and illuminate forward.

[0046] Specifically, there are three LEDs on the lamp holder, which are arranged in a circular array at the front of the lamp holder. The use of multiple LEDs can better cover and evenly illuminate the entire lens area.

[0047] Specifically, LED 22 is a halogen lamp.

[0048] Of course, in another embodiment, depending on the actual lighting function and needs, the lamp bead 22 can also be an LED lamp bead, an infrared lamp, etc.

[0049] In one embodiment, the front end of the lamp holder 21 has a mounting platform 24 protruding at the position corresponding to each lamp bead 22. The lamp beads 22 are inserted into the mounting platform 24 one by one. The rear end of the lamp cup 23 has an insertion hole 25 through the mounting platform 24 at the position corresponding to each lamp bead 22 for inserting the lamp bead 22 and the mounting platform 24. That is, the lamp bead 22 and the mounting platform 24 are inserted into the lamp cup 23 through the insertion hole 25 so that the lamp bead 22 is covered by the lamp cup 23. The rear side of the mounting platform 24 is fixed with a circuit board 26 by screws. The two conductive pins 221 at the rear end of the lamp bead 22 pass through the mounting platform 24 and are electrically connected to the circuit board 26. The circuit board is used to control whether the lamp bead works or not.

[0050] Specifically, the mounting platform 24 and the insertion hole are preferably circular to facilitate the insertion and installation of the two, and the circular structure also makes the insertion between the lamp cup and the mounting platform firm; of course, the mounting platform 24 and the insertion hole 25 can also be designed into other shapes, such as square, pentagon, etc.

[0051] In one embodiment, in addition to ventilating and cooling the light source assembly from the outside, to achieve better heat dissipation, at least one air inlet groove 27 is formed between the insertion hole 25 and the mounting platform 24, which connects the interior of the lamp cup and the air flow channel 13. The outer periphery of the front end of the lamp cup 23 is provided with several air holes 28 that connect the air inlet groove 27 and the air flow channel 13. Here, the airflow entering the air flow channel can enter the interior of the lamp cup through the air inlet groove, directly contact the lamp bead and dissipate heat from the lamp bead. The airflow entering the lamp cup flows outward through the air holes at the front end of the lamp cup into the air flow channel, and then blows out from the air outlet on the lens, so as to achieve the purpose of simultaneous heat dissipation from the inside and outside of the lamp cup, and further improve the heat dissipation effect of the light source assembly.

[0052] Specifically, a group of air holes consisting of several air holes 28 is provided at the position between two adjacent lamp beads on the lamp cup. The three groups of air holes are arranged in a ring array, so that the airflow entering the lamp cup can flow through each lamp bead and ensure that the airflow can circulate evenly throughout the entire lamp cup to achieve the purpose of uniform heat dissipation.

[0053] Specifically, the mounting platform 24 has several air inlet slots 27 recessed on its outer periphery and extending axially. To allow the air inlet slots 27 to connect the interior of the lamp holder and the airflow channel 13, the rear end face of the lamp holder 23 cannot abut against the front end face of the lamp base 21. That is, a gap needs to be formed between the rear end of the lamp holder 23 and the front end of the lamp base 21, connecting the air inlet slots 27 and the airflow channel 13. The front end of the lamp base 21 has at least one protruding post 29 with a height lower than that of the mounting platform 24. This allows the lamp holder 24 to insert into the insertion hole 25. At this time, the front end of the protruding post 29 abuts against the rear end face of the lamp cup 23, thereby limiting the insertion stroke of the mounting platform 24. This results in only a portion of the front end of the mounting platform 24 being inserted into the lamp cup, while a portion of the rear end is exposed outside the lamp cup. Consequently, the air inlet groove 27 provided on the outer periphery of the mounting platform 24 passes through the rear end of the lamp cup 23. That is, part of the air inlet groove 27 is located inside the lamp cup 23 and communicates with the internal space of the lamp cup 23, while part is located outside the lamp cup 23 and communicates with the air flow channel 13, thereby connecting the inner side of the lamp cup 23 and the air flow channel 13.

[0054] More specifically, when there are multiple lamp beads 22 and mounting platforms 24, the cooperation of multiple mounting platforms and insertion holes can achieve rotational limitation of the lamp holder. Therefore, only one protrusion 29 can be set in the middle of the lamp holder 21, while multiple mounting platforms 24 and lamp beads 22 are arranged in a ring array around the protrusion 29. When there is only one lamp bead 22 and one mounting platform 24, the mounting platform 24 and the lamp bead 22 are located in the middle of the lamp holder 21. At least two protrusions 29 located on both sides of the mounting platform 24 can be set on the lamp holder 21 to ensure the left and right balance of the structure after the lamp holder is fitted.

[0055] More specifically, the mounting platform 24 has four air inlet slots 27 on its outer periphery, which are arranged in a cross shape. The multiple air inlet slots can increase the air volume entering the lamp cup and improve the heat dissipation effect.

[0056] In one embodiment, a stop 241 may be provided on the outer periphery of the mounting platform 24 near the lamp holder. The stop 241 is used to stop the rear end face of the lamp cup 23. The front end face of the stop 241 is flush with the front end of the protrusion 29.

[0057] In one embodiment, in order to make the connection between the lamp cup 23 and the lamp holder 21 secure, a threaded hole 291 is provided in the middle of the protrusion 29, and a screw hole for screws to pass through is provided at the rear end of the lamp cup 23 at the position corresponding to each threaded hole 29, so that the lamp cup 23 and the lamp holder 21 are locked by screws.

[0058] In one embodiment, the light source device 100 further includes a ring 4 fitted around the outer periphery of the lens 3. The inner periphery of the ring 4 is recessed with an annular groove 41 for inserting the outer periphery of the lens 3. The outer periphery of the front end of the lamp cup 23 is radially protruding with an annular platform 231. The outer periphery of the annular platform 231 is inserted into the annular groove 41. The ring 4 is fitted into the illumination port 11. The fixing action between the ring 4 and the lamp cup 23 allows the light source assembly 2 to be suspended in the middle of the internal cavity of the lamp cup holder 1. The portion of the annular platform 231 exposed outside the ring 4 is provided with at least one through hole 232 that runs through the front and back and communicates with the air flow channel 13. The lens 3 is provided with an air outlet 31 at the position corresponding to each through hole 232.

[0059] Specifically, the ring 4 is made of silicone, which gives it a certain degree of flexibility, making it easy to install with the lens and lamp cup.

[0060] Specifically, there are three through holes 232 and three air outlet holes 31, which are arranged in a ring array.

[0061] Specifically, the width of the annular groove 41 is less than or equal to the sum of the thicknesses of the lens 3 and the annular stage 231, ensuring that the annular sleeve clamps the lens and the annular stage.

[0062] In one embodiment, the ring 4 can be installed at the irradiation port 11 by means of a sleeve.

[0063] In another embodiment, such as Figure 10 As shown, in order to facilitate the synchronous fixing and installation of the ring 4 and the light source device, a ring-shaped cover is provided in the middle of the air outlet end of the external air duct, which fits into the front end of the lamp holder 1. The inner end face of the ring 4 abuts against the front end face of the lamp holder 1. A limiting part 15 is provided on the inner circumference of the cover 14, which abuts against the outer end face of the ring 4. That is, the ring 4 is clamped by the cover 14 and the lamp holder 1, thereby realizing the synchronous installation and fixing of the light source assembly 2.

[0064] Specifically, such as Figure 5 As shown, the cavity inside the lamp holder 1, along its axial direction from the back to the front, includes a first section 141 with a uniform aperture, a flared drainage section 142 with gradually increasing aperture, and a second section 143 with a uniform aperture. The inner diameter of the second section 143 is larger than that of the first section 141 and connects with the maximum inner diameter of the drainage section 142, while the first section connects with the minimum inner diameter of the drainage section 142. The light source assembly is located inside the second section 143. In this structure, the airflow entering the lamp holder is concentrated by the relatively small aperture of the first section, and then the airflow flows outward along the drainage section 142. When the airflow reaches the second section 143, the airflow is reflected and guided towards the light source assembly in the center. As a result, part of the airflow flows forward along the airflow channel, and the other part can enter the lamp holder along the air inlet groove 27. The second section 143 with a larger and uniform aperture, due to its increased cross-sectional area, can reduce the airflow velocity and improve the flow stability.

[0065] In another implementation case, such as Figure 10 As shown, in order to make the outward-shielded light have better diffusion and softer light, a number of raised convex spheres 32 are provided on the outer side of the lens 3 to form a number of convex mirror structures on the outer side of the lens. Utilizing the principle of convex mirrors, the convex spheres 32 cause the light to be refracted at different angles during the outward-shielding process, resulting in good diffusion and making the light softer.

[0066] In another implementation, lens 3 is made of acrylic glass, such as PE I or PPS, and the lens surface is designed to be frosted to make the light softer and can also be adjusted to different colors of light effects.

[0067] In another implementation, the lamp cup 23 is made using a drawing process, which, compared to the die-casting process used in existing lamp cups, allows the lamp cup 23 to be made thinner, resulting in a lighter weight and better heat dissipation.

[0068] In another implementation, the lamp cup 23 can also be made of other materials such as magnesium alloy with better heat dissipation performance.

It also includes a light source device 100 as described in Embodiment 1. The light source device 100 is disposed within the air outlet of the main unit 200, and the air inlet 10 of the light source device 100 is communicating with the air outlet of the exhaust device 201, so that the airflow drawn in by the exhaust device when the solar-powered hair dryer is working can flow through the interior of the light source device 100, thereby achieving the purpose of ventilation and heat dissipation inside the light source device.

[0071] In one embodiment, the main unit 200 includes a blower 203 and a handle 204 located at the lower end of the blower 203. An exhaust device 201 is located inside the handle 204, and a through hole 202 is located at the lower end of the handle 204 and below the exhaust device 201. A light source device 100 is located in the middle of the inner side of the blower 203. An airflow heating channel 205 is formed between the light source device 100 and the inner wall of the blower 203, which communicates with the air outlet of the exhaust device 201.

[0072] In one embodiment, an air outlet is formed at the front end of the air duct 203, which surrounds the light source device 100 and communicates with the airflow heating channel 205. An installation space 207 is provided on the inner side of the rear end of the air duct 203, which is separated from the airflow heating channel 205. The installation space 207 is connected to the air outlet of the exhaust device and the air inlet 10 at the rear end of the light source device 100. A main board 208 is provided in the installation space 207, which is electrically connected to the circuit board 26 and the exhaust device 201.

[0073] In one embodiment, a heat insulation cylinder 209 and a heat insulation ring 210, which are fitted onto the outside of the heating frame 206, are arranged sequentially from the outside to the inside on the inner wall of the air duct 203.

[0074] In one embodiment, the cover 14 is integrally formed with the heat insulation cylinder 209, and the cover 14 is located at the air outlet end of the front end of the heat insulation cylinder, and an air outlet is formed between the heat insulation cylinder 209 and the cover 14, surrounding the cover.

[0075] Specifically, the heat insulation ring is made of mica material; mica material itself has very low thermal conductivity, which can effectively prevent heat conduction.

[0076] In one embodiment, an iron ring 211 is embedded between the front end of the cylinder 203 and the front end of the heat insulation cylinder 209.

[0077] In one embodiment, the ventilation device is preferably a turbo fan or a high-speed blower.
