Abstract
Description
Technical Field
[0001] This utility model belongs to the field of hair dryer technology, specifically relating to a solar-powered hair dryer nozzle and a solar-powered hair dryer with good heat insulation performance. 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 existing technology, a nozzle is usually attached to the air outlet of the hair dryer. The hot air blown out by the hair dryer is discharged through the nozzle, which absorbs a lot of heat, causing the nozzle to get hot. After use, the user will put the hair dryer away and may come into contact with the nozzle during the process, resulting in burns.
[0004] Secondly, with the rapid development of photoelectric technology in recent years, photoelectric hair dryers, as a new type of product combining phototherapy and rapid hair drying functions, have gradually entered the market and received widespread attention from consumers. These hair dryers integrate photoelectric devices (such as LED arrays) inside the body, releasing specific wavelengths of light, such as infrared or visible light, while blowing air to promote scalp blood circulation, accelerate hair moisture evaporation, and nourish the hair. However, traditional hair dryer nozzles, especially those designed to improve drying efficiency by changing the airflow shape, such as guiding a ring-shaped air outlet into a wide strip, face challenges when applied to photoelectric hair dryers. These nozzles only have air guiding functions and lack light transmission capabilities, therefore they cannot be used in conjunction with photoelectric hair dryers. Specifically, these nozzles are usually fixed by snapping onto the hair dryer's outlet, and their structure often completely covers the path of the light emitted by the photoelectric device. As a result, the light intended for scalp care and treatment is completely blocked by the nozzle, causing the photoelectric hair dryer to lose its unique phototherapy function and significantly weakening its market competitiveness. Utility Model Content
[0005] The purpose of this utility model is to overcome the existing technical defects and provide a light-powered air duct nozzle with good heat insulation performance, which can simultaneously achieve the purpose of heat insulation and light transmission, thus solving the problems of poor heat insulation and lack of light transmission in existing air nozzles.
[0006] In the first aspect, in order to solve the above-mentioned technical problems, this utility model provides a solar energy duct nozzle with good heat insulation performance, including a main body with an inner cover and an outer cover forming a double-layer structure, and a heat insulation cavity is formed between the inner cover and the outer cover. An air outlet channel is provided on the inner side of the front end of the inner cover. A light-transmitting window is provided through at least one side of the main body, extending along the air outlet direction of the air outlet channel and located outside the air outlet channel. An air guide groove is recessed at the rear end of the inner cover, surrounding the light-transmitting window and communicating with the air outlet channel.
[0007] Furthermore, the front end of the inner cover extends to provide a flat air outlet with an air outlet channel, i.e., the air outlet channel is also flat; the rear end of the inner cover forms a first annular portion and a second annular portion spaced around the first annular portion, and a light-transmitting window is formed between the front end of the first annular portion and the two outer sides of the air outlet. The outer cover has a light-transmitting hole at the position corresponding to the light-transmitting window, and a light-guiding cavity communicating with the two light-transmitting windows is formed on the inner side of the rear end of the first annular portion; an air guide groove communicating with the air outlet channel is formed between the first annular portion and the second annular portion.
[0008] Furthermore, a connecting port is provided at the intersection of the air guide trough and the air outlet channel to connect the two.
[0009] Furthermore, the rear end of the first annular portion is provided with a connecting ring extending out of the second annular portion along the axial direction, and the outer diameter of the connecting ring is smaller than the outer diameter of the first annular portion.
[0010] Furthermore, the outer cover includes a flat, annular portion fitted outside the air outlet and an annular sleeve portion fitted outside the second annular portion. The light-transmitting holes are formed between the front end of the annular sleeve portion and the two outer sides of the flat portion. The rear end of the annular sleeve portion has an opening at the position corresponding to the flat portion for the air outlet portion to be inserted, and the rear end of the air outlet portion has an arc-shaped connecting portion that fills the opening.
[0011] Furthermore, the rear outer periphery of the air outlet is provided with a stop cover that covers the rear end of the flat part, the inner side of the stop cover is provided with a positioning groove, and the rear end of the flat part is provided with a positioning rib that is inserted into the positioning groove.
[0012] Furthermore, at least one first buckle is provided on both outer sides of the front end of the air outlet, and a second buckle is provided on the inner wall of the flat part to engage with the first buckle in a one-to-one manner; a plurality of isolation ribs are provided on the outer wall of the inner cover and / or the inner wall of the outer cover to separate the inner cover and the outer cover.
[0013] Furthermore, a plurality of magnetic elements are embedded on the rear end face of the annular sleeve.
[0014] Furthermore, the inner cover is made of PPS, and the outer cover is made of nylon reinforcement.
[0015] Secondly, this utility model embodiment also provides a solar-powered hair dryer, including a solar-powered hair dryer nozzle as described in any of the first aspects.
[0016] This utility model has the following beneficial effects:
[0017] 1. Firstly, the main body consists of an inner and outer cover forming a double-layer structure. A heat insulation cavity is formed between the inner and outer covers, meaning there is a certain gap between the inner and outer walls. Air is blown out from the inner cover. In use, the inner cover part is heated normally by hot air, but the heat insulation cavity between the two layers prevents the heat on the inner cover from being effectively conducted to the outer cover part, thus achieving the purpose of heat insulation. The heat insulation performance is good, thereby solving the problem of scalding and burns caused by the high surface temperature of the nozzle during use.
[0018] 2. A light-transmitting window is also provided on at least one side of the nozzle, extending along the air outlet direction of the air outlet channel, so that it can be used in conjunction with the solar hair dryer. The light emitted by the solar hair dryer can pass through the nozzle without obstruction through the light-transmitting window and act on the user's hair synchronously with the airflow blown out from the air outlet channel. This design not only retains the original phototherapy function of the solar hair dryer, but also achieves a perfect combination of light energy and airflow, greatly improving the product's performance and user satisfaction.
[0019] 3. Two spaced-apart annular sections are formed at the rear end of the inner cover to cooperate with the flat air outlet at the front end, so that the channels for airflow and light transmission on the front and rear ends of the inner cover form an interlaced design. The inner side of the first annular section at the rear end of the inner cover is a light guide cavity and the outer side is an air guide groove, while the inner side of the air outlet at the front end of the inner cover is an air outlet channel and the outer side is a light transmission window; and the two annular sections at the rear end of the inner cover are used in conjunction with the light-emitting section in the middle of the air outlet end of the air duct and the air outlet surrounding the light-emitting section.
[0020] 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

[0034] 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.
[0035] 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.
[0036] Example 1
[0037] like Figures 1 to 10As shown in the figure, the solar energy duct nozzle 100 with good heat insulation performance shown in this embodiment includes a main body with an inner cover 1 and an outer cover 2 sleeved together to form a double-layer structure, and the inner cover 1 and the outer cover 2 are spaced apart to form a heat insulation cavity 3 between the inner cover 1 and the outer cover 2. An air outlet channel 10 is provided on the inner side of the front end of the inner cover 1. A light-transmitting window 4 is provided through at least one side of the main body, extending along the air outlet direction of the air outlet channel and located outside the air outlet channel. An air guide groove 11 is recessed at the rear end of the inner cover 1, surrounding the light-transmitting window 4 and communicating with the air outlet channel 10.
[0038] Specifically, in the above structure, the main body consists of an inner and outer cover forming a double-layer structure. A heat-insulating cavity is formed between the inner and outer covers, meaning there is a certain gap between their inner and outer walls. Air is blown out from the inner cover. During use, the inner cover is heated normally by the hot air, but the heat from the inner cover cannot be effectively transferred to the outer cover due to the heat-insulating cavity between the two layers, achieving heat insulation. This provides excellent heat insulation performance, thus solving the problem of burns and scalding caused by the high surface temperature of the nozzle during use. Furthermore, the light-transmitting window allows light to be used for blowing air. The light emitted by the machine can pass through the nozzle without obstruction through the light-transmitting window and act on the user's hair synchronously with the airflow blown out from the air outlet. This design not only retains the original phototherapy function of the light-generating hair dryer, but also achieves a perfect combination of light energy and airflow. While drying hair, the hair dryer can also provide a soft light effect, allowing users to enjoy fast hair drying while also experiencing the comfortable care from light energy, greatly improving the product's performance and user satisfaction. In addition, this ingenious structural design makes the nozzle both practical and aesthetically pleasing, meeting users' dual needs for product functionality and appearance.
[0039] In one embodiment, a light-transmitting window 4 is provided on both sides of the main body. The light-transmitting windows 4 on both sides are symmetrically distributed. A light guide cavity 12 is provided at the middle of the rear end of the inner cover 1, which is connected to both light-transmitting windows 4. The air guide groove 11 is arranged around the light guide cavity 12, thereby forming a double-sided light-transmitting structure. The light energy emitted by the light-powered blower is emitted outward along the light guide cavity 12 and then emitted from the light-transmitting windows 4 on both sides, which improves the illumination area and illumination effect. The structure set on both sides of the light-transmitting window does not affect the normal flow of air.
[0040] Specifically, such as Figures 2 to 8As shown, an air outlet 13 with an air outlet channel 10 and a flat shape is provided at the front end of the inner cover 1. Correspondingly, the air outlet channel is also designed to be flat, which can better concentrate the air blown out by the hair dryer, so that the airflow can better act on the hair, improve the blow-drying effect, and facilitate the formation of light-transmitting windows on both outer sides to cooperate with the light guide cavity 12 at the rear end. A first annular part 14 and a second annular part 15 are formed at intervals around the first annular part 14 at the rear end of the inner cover 1. A light-transmitting window 4 is formed between the front end of the first annular part 14 and the two outer sides of the air outlet 13. A light-transmitting hole 21 is provided on the outer cover 2 at the position corresponding to the 4 light-transmitting windows, and a light guide cavity 12 is formed on the inner side of the rear end of the first annular part 14. An air guide groove 11 communicating with the air outlet channel 10 is formed between the first annular part 14 and the second annular part 15.
[0041] More specifically, in order to separate the air outlet duct 10 and the light-transmitting window 4, the front end of the air outlet 13 is designed as an open air outlet, and the rear end is designed as a closed air outlet; however, in order to allow the air blown out by the blower to enter the air outlet duct 10, a connecting port 16 is provided at the position of the air guide groove 11 at the rear end of the air outlet 13 to connect the two.
[0042] More specifically, such as Figures 2 to 8 As shown, the outer diameter of the first annular portion 14 and the second annular portion 15 is greater than the thickness of the air outlet portion 13 and less than the vertical length of the air outlet portion 13. The outer peripheries of the first annular portion 14 and the second annular portion 15 extend symmetrically to both sides of the air outlet portion 13, resulting in two intersections between the air guide groove 11 and the air outlet channel 10 in the air outlet portion 13. At each of these intersections, a connecting port 16 is provided to connect the air outlet channel 10 and the air guide groove 11. In this structure, the air blown out by the hair dryer can be evenly distributed throughout the air outlet channel 10 through the air guide groove 11 and the two connecting ports 16. This facilitates the airflow to be evenly blown out from the air outlet channel 10. The air guide groove 11 also helps to reduce turbulence and vortexes when the airflow enters the air outlet channel 10, making the airflow more stable and uniform. This helps to improve the efficiency of the airflow, speed up the drying of the hair, and also helps to reduce the noise generated when the airflow passes through. This provides users with a more comfortable user experience, especially when it is necessary to use the solar hair dryer for a long time.
[0043] In one embodiment, both the light-transmitting window 4 and the light-transmitting hole 21 are arranged in a fan shape.
[0044] Specifically, the light-transmitting window 4 and the light-transmitting hole 21 are designed in a fan shape, which means that they are not simple circles, ovals or rectangles, but have curved edges, similar to the outline of a scallop or fan. This design aims to maximize the light-transmitting area while maintaining the integrity and aesthetics of the inner and outer cover structures.
[0045] More specifically, the fan-shaped light-transmitting window 4 and light-transmitting hole 21 design make the light-transmitting area larger than traditional shapes (such as circles, rectangles, etc.), thereby improving the light energy transmittance emitted by the light-powered hair dryer. This helps to enhance the light therapy effect, allowing users to enjoy fast hair drying while also experiencing the comfortable care from light energy.
[0046] In one embodiment, the rear end of the first annular portion 14 is provided with a connecting ring 17 extending out of the second annular portion 15 along the axial direction, and the outer diameter of the connecting ring 17 is smaller than the outer diameter of the first annular portion 14.
[0047] Specifically, when installing the nozzle on the solar-powered hair dryer, the connecting ring 17 is used to engage with the light-emitting part located in the middle of the air outlet of the hair dryer. That is, the front end of the light-emitting part will be provided with a slot for engaging with the connecting ring, making the installation process of the nozzle simpler and faster. Users can easily fix the nozzle to the main body of the solar-powered hair dryer without complicated operations or tools, which greatly shortens the installation time and improves work efficiency. The air guide groove 11 between the first annular part 14 and the second annular part 15 is just right to connect with the air outlet of the hair dryer surrounding the light-emitting part.
[0048] In one embodiment, such as Figures 9 to 10 As shown, the outer cover 2 includes a flat portion 22 that is also flat and annular, which is sleeved on the outside of the air outlet portion 13, and an annular sleeve portion 23 that is sleeved on the outside of the second annular portion 15. Light-transmitting holes 21 are formed between the front end of the annular sleeve portion 23 and the two outer sides of the flat portion 22.
[0049] Specifically, such as Figures 5 to 10 As shown, the rear ends of the first annular portion 14 and the second annular portion 15 protrude axially from the rear end of the air outlet portion 13, which facilitates the formation of air guide grooves and light guide cavities. Similarly, the rear end of the annular sleeve portion 23 also protrudes axially from the rear end of the flat portion 22. In order to realize the purpose of installing the inner cover inside the outer cover, the rear end of the annular sleeve portion 23 is provided with an opening 24 for inserting the air outlet portion 13 at the position corresponding to the flat portion 22, and the rear end of the air outlet portion 13 is provided with an arc-shaped connecting portion 18 that fills the opening 24, so that the outer periphery of the annular sleeve portion 23 forms a complete circle after the two are assembled, which improves the aesthetics of the overall structure.
[0050] In one embodiment, in order to limit the travel of the inner cover when it is inserted into the rear cover, a stop cover 19 is provided on the outer periphery of the upper and lower ends of the rear side of the air outlet 13, which covers the rear end of the flat part 11. The inner side of the stop cover 19 is recessed with a positioning groove 191, and the rear end of the flat part 22 is provided with a positioning rib 25 that is inserted into the positioning groove 191, so as to achieve the purpose of assembly positioning.
[0051] In one embodiment, such as Figures 7 to 10As shown, two first buckles 131 are protruding on both outer sides of the front end of the air outlet 13, and a second buckle 221 is provided on the inner wall of the flat part 22 to engage with the first buckles 131, thereby realizing the engagement and fixation between the inner cover 1 and the outer cover 2.
[0052] In another embodiment, slots can be provided on the two outer sides of the front end of the air outlet, and buckles that correspond to and engage with the slots can be provided on the inner wall of the flat part 22. In this way, while the engagement and fixation can be achieved, the air outlet can also be easily inserted into the flat part because there are no protruding buckles on the air outlet.
[0053] In one embodiment, such as Figures 7 to 10 As shown, in order to achieve isolation between the inner cover 1 and the outer cover 2, a number of isolation ribs 20 are provided on the outer wall of the inner cover 1 and the inner wall of the outer cover 2 to separate the inner cover 1 and the outer cover 2.
[0054] In one embodiment, such as Figures 2 to 4 As shown, a plurality of magnetic components 26 are embedded on the rear end face of the annular sleeve 23 for magnetic connection with the air outlet of the solar hair dryer.
[0055] Specifically, the nozzle is magnetically connected to the main body of the solar-powered hair dryer via magnetic attachment 26, allowing the nozzle to rotate 360 degrees along the main body. In other words, when installing the nozzle, the user simply brings it close to the main body, and the magnetic attachment 26 automatically attracts and attaches it. Due to the magnetic force, the nozzle is firmly fixed to the main body without the need for additional fasteners or tools. When it is necessary to remove the nozzle, the user simply pulls it gently, and the magnetic connection between the magnetic attachments 26 is broken, allowing the nozzle to be easily removed from the main body. This design makes the disassembly process equally simple and quick, requiring no complicated operations or tools.
[0056] Specifically, the magnetic component 26 can be a magnet or an iron block; this depends on the material of the magnetic component at the air outlet of the solar hair dryer. When the magnetic component at the air outlet of the solar hair dryer is a magnet, the magnetic component 26 at the rear end of the annular sleeve 23 can be either a magnet or an iron block. However, when the magnetic component at the air outlet of the solar hair dryer is an iron ring, the magnetic component 26 at the rear end of the annular sleeve 23 must be a magnet.
[0057] In one embodiment, the inner cover is made of PPS, which is more heat-resistant, because the inner and outer layers of the nozzle have good heat insulation performance. The outer cover can be made of nylon reinforcement. The inner and outer covers made of two different materials can meet the requirements of high temperature resistance and facilitate the interlocking installation between the two. If the inner and outer covers of the inner and outer layers are both made of PPS, it would be inconvenient to interlock them due to their high hardness.
[0058] Example 2
[0059] like Figures 1 to 12 As shown, this embodiment also provides a solar-powered hair dryer, including a solar-powered hair dryer body 200 and a solar-powered hair dryer nozzle 100 as described in Embodiment 1. The solar-powered hair dryer nozzle 100 is magnetically connected to the air outlet end of the solar-powered hair dryer body 200 via a magnetic component.

Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
