Description

TECHNICAL FIELD

[0001] The present application relates to the field of hairdressing, in particular to a new type of far infrared hair dryer. BACKGROUND

[0002] The hair dryer is a personal care small household appliance that can quickly dry the hair. It can heat the air by heating wires, so that the hair is dried faster, shortens the time of drying the hair, and facilitates people's life. Since far infrared rays have strong penetration and radiation, they have significant temperature control effect and resonance effect. They are easily absorbed by objects and converted into internal energy of the objects. After the far infrared rays are absorbed by the human body, they can make the water molecules in the body resonate, activate the water molecules, and enhance the intermolecular bonding force, thereby activating biological macromolecules such as proteins and making biological cells at the highest vibration energy level. Due to the resonance effect of biological cells, far infrared heat energy can be transmitted to the deeper part of the human body. The temperature of the deeper part rises, and the generated heat is emitted from the inside to the outside. The intensity of this effect causes the expansion of capillaries, promotes blood circulation, strengthens the metabolism between tissues, increases the regeneration capacity of tissues, improves the immune capacity of the body, and adjusts the abnormal excitement state of the spirit, thereby playing a role in medical care. In the process of hairdressing, if negative ions can be released, static electricity can be neutralized, the scale-like surface layer can be flattened, and the hair can be repaired and tamed, thereby playing a role in hair care.

[0003] In order to make the air outlet of the hair dryer produce negative ions and far infrared waves, and bring hair care and beauty effects, a ceramic heating body is arranged in the hair dryer corresponding to the heating mechanism to the air outlet. The emissivity of the ceramic heating body at room temperature (25℃ to 150℃) is generally greater than 85%, has high light-heat conversion efficiency, and can produce negative ions. However, the existing ceramic heating body is mainly arranged in front of the heating mechanism in a honeycomb structure. The combination of the ceramic heating body and the heating mechanism is not compact in structure, which causes the overall volume of the hair dryer to increase, and the combination of the ceramic heating body and the heating mechanism leads to complex internal fluid channels, which will cause great resistance to the air outlet and make the hair dryer have great noise when in use. Therefore, it is necessary to propose a new technical scheme to solve the above problems. SUMMARY

[0018] Preferably, the fixing component includes a first fixing plate and a second fixing plate.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] By further improving the fluid flow path of traditional hair dryers, a section corresponding to the fluid outlet is designed as an annular chamber. This creates negative pressure at the center of the fluid outlet during operation, achieving a vortex effect to enhance the guided airflow. Simultaneously, the annular air outlet reduces the concentration of far-infrared waves at the center, allowing them to disperse in a ring shape.

The far-infrared ceramic coating is made by mixing far-infrared ceramic powder with high-temperature resistant adhesive and then applying it to the ring-shaped heat dissipation component. When the heating element generates heat, it can dissipate the heat through the ring-shaped heat dissipation component to provide heat for drying hair. It also makes full use of the heat dissipation of the ring-shaped heat dissipation component, so that the temperature of the far-infrared ceramic coating can reach between 25℃ and 150℃, thereby generating negative ions and far-infrared waves. The fixed bracket allows the ring-shaped heat dissipation component to be suspended and wound in the ring-shaped cavity, thereby maximizing the compactness of the overall structure, ensuring smooth airflow, reducing air obstruction and noise, and providing users with a more compact and comfortable practical experience.

Detailed Implementation

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-6 In this embodiment of the invention, a novel far-infrared hair dryer includes:

[0035] The body 10 has a fluid inlet 11 at the rear end and a fluid outlet 12 at the front end, and a hand-held part 50 is provided at the lower end of the body 10.

[0036] Fluid flow path 20 is provided in the body 10 and extends from fluid inlet 11 to fluid outlet 12.

[0037] The conveying mechanism 30 is disposed in the fluid flow path 20, and the conveying mechanism 30 drives the fluid to flow from the fluid inlet 11 to the fluid outlet 12;

[0038] Heating mechanism 40 is disposed in fluid flow path 20 and is used to heat the fluid in fluid flow path 20;

[0039] The fluid flow path 20 has an annular chamber 21 at its front end, and the fluid outlet 12 is an annular opening structure that is connected to the annular chamber 21. The heating mechanism 40 is disposed in the annular chamber 21. The heating mechanism 40 includes an annular heat dissipation component 41 suspended and wound in the annular chamber 21, an annular heating element 42 embedded in the annular heat dissipation component 41, a far-infrared ceramic coating (not shown) disposed on the outer surface of the annular heat dissipation component 41, and a fixed bracket 44 fixed in the annular chamber 21 for supporting the annular heat dissipation component 41.

[0040] This invention further improves the fluid flow path 20 of a traditional hair dryer by setting a section corresponding to the fluid outlet 12 as an annular chamber 21. This allows negative pressure to be generated at the center of the fluid outlet 12 during operation, achieving a vortex effect to improve the guiding airflow. At the same time, the annular air outlet reduces the concentration of far-infrared waves at the center of the air outlet, allowing the far-infrared waves to disperse in an annular manner. This improves the uniformity of heat radiation dispersion and the uniform supply of negative ions, preventing excessive local radiation from damaging the scalp during use. As a result, it provides users with more efficient medical and health care and hair care effects.

[0041] Based on the annular chamber 21, a heating mechanism 40 is assembled by setting an annular heat dissipation component 41, an annular heating element 42, a far-infrared ceramic coating, and a fixing bracket 44. The annular heating element 42 is used to generate heat by electrical connection, and the annular heat dissipation component 41 is used for heat conduction. A far-infrared ceramic coating is coated on the outer surface of the annular heat dissipation component 41. The far-infrared ceramic coating is made by mixing far-infrared ceramic powder with high-temperature resistant adhesive and then applying it to the annular heat dissipation component 41. When the heating element generates heat, it can dissipate the heat through the annular heat dissipation component 41 to provide heat dissipation for drying hair. It also makes full use of the heat dissipation of the annular heat dissipation component 41 so that the temperature of the far-infrared ceramic coating can reach between 25°C and 150°C, thereby generating negative ions and far-infrared waves. The fixing bracket 44 is set so that the annular heat dissipation component 41 can be suspended and wound in the annular chamber 21, thereby maximizing the compactness of the overall structure, ensuring smooth airflow, reducing wind obstruction and noise, and providing users with a more compact and comfortable practical experience.

[0042] Please refer to Figure 2 , Figure 3 and Figure 5 Inside the main body 10, there is a first tube 13 connected to the fluid inlet 11 and a second tube 14 connected to the fluid outlet 12. The first tube 13 and the second tube 14 are connected to each other, forming a fluid flow path 20 inside the first tube 13 and the second tube 14. This can isolate the circuit inside the main body 10, thereby improving the smoothness of the fluid flow path 20 and further realizing the noise reduction function. The conveying mechanism 30 is set inside the first tube 13, and the heating mechanism 40 is set inside the second tube 14. A guide component 15 extending into the second tube 14 is set in the middle of the fluid outlet 12. The fluid outlet 12 forms an annular opening structure through the guide component 15, and the interior of the second tube 14 forms an annular chamber 21 through the guide component 15. The diameter of the first tube 13 is smaller than the diameter of the second tube 14. A sloped transition end 16 is set between the first tube 13 and the second tube 14. The first tube 13 and the second tube 14 are sealed together through the sloped transition end 16, which improves the guiding flow effect of the fluid.

[0043] Please refer to Figures 2-5The annular heat dissipation assembly 41 includes a first annular body 411 and a second annular body 412 sleeved outside the first annular body 411. An annular heating element 42 is fixed between the first annular body 411 and the second annular body 412. Multiple evenly arranged heat dissipation fins 413 are arranged around the inner side of the first annular body 411 and the outer side of the second annular body 412. A far-infrared ceramic coating is applied to the heat dissipation fins 413, and the heat dissipation fins 413 are parallel to the fluid flow path 20. This arrangement greatly improves the heat dissipation effect of the annular heat dissipation assembly 41 and provides sufficient surface area for applying the far-infrared ceramic coating, thereby significantly improving heat dissipation efficiency. In addition to improving the far-infrared wave generation efficiency, the heat dissipation fins 413 are parallel to the fluid flow path 20, which can minimize the obstruction effect on the wind. To securely install the annular heating element 42, so that the annular heating element 42 can be pressed between the first annular body 411 and the second annular body 412, the second annular body 412 includes two semi-circular arc portions 414 that fit together. A mating part is provided at the position where the two semi-circular arc portions 414 meet, and a screw structure is provided on the mating part to lock the two semi-circular arc portions 414. A wiring notch 415 is provided at the rear end of one of the semi-circular arc portions 414, and the annular heating element 42 is connected to the wire through the wiring notch 415.

[0044] Please refer to Figures 2-6 The fixed bracket 44 includes several fixed components 441, which are uniformly arranged circumferentially around the annular heat dissipation component 41. The fixed components 441 abut against the second tube body 14 and the guide component 15, so that the annular heat dissipation component 41 can be suspended in the annular chamber 21, thereby reducing wind resistance and fully generating heating, far-infrared radiation and negative ion efficiency. The fixed components 441 include a first fixed plate 442 and a second fixed plate 443. The upper and lower ends of the first fixed plate 442 and the second fixed plate 443 are provided with fixed parts 444. The first fixed plate 442 and the second fixed plate 443 are fixedly connected through the fixed parts 444, so that the first fixed plate 442 and the second fixed plate 443 form a closed loop structure around the annular heat dissipation component 41. The first fixed plate 442 is located inside the annular heat dissipation component 41 and abuts against the guide component 15, and the second fixed plate 443 is located outside the annular heat dissipation component 41 and abuts against the second tube body 14.

[0045] Please refer to Figure 3 , Figure 4 and Figure 6 In order to reduce the heat dissipation around the body 10 and enable the heat to achieve more efficient guiding flow, a snap-fit ​​notch 445 is provided at the end of the second fixing plate 443 that abuts against the second tube body 14. Multiple fixing components 441 are fixedly fitted with heat insulation rings 45 through the snap-fit ​​notch 445, and the heat insulation rings 45 abut against the inner side of the second tube body 14.

[0046] Please refer to Figures 1-3 The handheld part 50 is equipped with a main control board 51 and a cable 52. The lower end of the handheld part 50 is equipped with a fixing ring 53. The cable 19 passes through the fixing ring 53 and connects to the main control board 51. The main control board 51 is electrically connected to the conveying mechanism 30 and the annular heating element 42 respectively, and is used to control the air volume of the conveying mechanism 30 and the temperature of the annular heating element 42. The surface of the handheld part 50 is equipped with a button, which is connected to the main control board 51 to start, stop and control the hair dryer. The cable is electrically connected to the main control board 51 and is connected to a plug (not shown in the figure) to power the hair dryer.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
