Abstract
Description
Technical Field
[0001] The utility model relates to the field of hair styling, in particular to a fluffy hair nozzle. Background Art
[0002] As people's living standards improve year by year, they increasingly prioritize hair care. A diffuser nozzle, as a hair dryer accessory, evenly disperses airflow, making drying hair more natural. When used to dry curly hair, it adds volume and volume, while also helping to reduce frizz. Diffuser nozzles typically feature comb teeth with air outlets, allowing hot air to penetrate directly into the hair for styling. The gentle airflow and concentrated heat create a more fluffy, comfortable, and comfortable hair after drying. Fluffy nozzles are particularly well-suited for drying curly hair and are not suitable for high-speed airflow. Furthermore, when connected to a hair dryer, the nozzle can alter the noise level. The airflow entering the diffuser nozzle rubs against its inner wall, generating noise. The higher the air speed, the louder the noise. Therefore, reducing and evenly distributing the air speed is key to addressing noise levels.
[0003] Therefore, in order to improve the user experience, it is necessary to reduce the overall noise level and wind speed after the fluffing nozzle is connected to the hair dryer, and the structure of the nozzle needs to be optimized to reduce the wind speed, make the wind speed uniform and reduce noise. Utility Model Content
[0004] In order to solve the technical problems mentioned in the background technology, the utility model provides a fluffing nozzle.
[0005] The technical solution of the utility model is as follows:

[0007] Preferably, the sound insulation board includes a closed area and a connecting portion connected to the closed area, the connecting portion is connected to the deflector, and the edge of the closed area and the inner wall of the deflector form the ventilation opening.

[0024] The contents of the utility model are described in detail below through specific implementation methods.
[0025] A fluffing nozzle comprises an air inlet 1 and an air outlet 2, wherein the air inlet 1 is used to receive an air flow from a hair dryer, and the air outlet 2 is used to emit the aforementioned air flow; a deflector 3, which defines a diffusion air chamber 4, and the air flow traveling from the air inlet 1 to the air outlet 2 passes through the air chamber 4, wherein the nozzle further comprises a sound insulation board 5, which is positioned between the air inlet 1 and the air outlet 2, and the sound insulation board 5 is placed horizontally in the air chamber 4 to divide the air chamber 4 into a first chamber 7 located below the sound insulation board 5 and a second chamber 8 located above the sound insulation board 5, and at least one vent 6 is formed between the sound insulation board 5 and the deflector 3, and at least part of the aforementioned air flow is blocked by the sound insulation board 5 and rebounds to the first chamber 7, then enters the second chamber 8 through the vent 6 and is discharged from the air outlet 2.
[0026] Adding a soundproofing panel 5 to the airflow path blocks the airflow, causing it to rebound back into the first chamber 7. The airflow is then discharged through vents 6 located on the periphery of the first chamber 7 into the second chamber 8, and finally out of the airflow outlet 2. The airflow is blocked by the soundproofing panel 5, which reduces the velocity of the airflow exiting the airflow outlet 2. The soundproofing panel 5 also physically isolates the sound through the direct obstruction of the sound, achieving a noise reduction effect. Furthermore, the soundproofing panel 5 can be made of plastic, but preferably, it should be made of a material with numerous tiny pores, such as foam or lime wool, as these pores absorb sound and contribute to noise reduction.
[0027] More specifically, the soundproofing panel 5 includes an enclosed area 501 and a connecting portion 502 connected to the enclosed area 501. The connecting portion 502 is connected to the deflector 3. The edge of the enclosed area 501 and the inner wall of the deflector 3 form the vent 6. Airflow from the air inlet 1 first enters the first chamber 7. Upon encountering the enclosed area 501, it is redirected and diffused toward the air inlet 1 before entering the second chamber 8 through the vent 6. The enclosed area 501 improves the airflow barrier, helping to reduce wind speed. It also provides a certain degree of physical isolation from sound, reducing noise. The connecting portion 502 is fixed to the deflector 3 via screws. In this example, the vertical projection of the enclosed area 501 (i.e., perpendicular to the air inlet) is circular (it can also be square or other shapes), and the air inlet 1 is also circular.
[0028] Furthermore, along the direction perpendicular to the air flow inlet 1, the projection of the enclosed area 501 covers the air flow inlet 1, so that almost all of the air flow entering from the air flow inlet 1 can pass through the enclosed area 501 for blocking, thereby reducing the wind speed and noise while making the wind speed uniform; and preventing part of the air flow from being directly discharged from the air flow outlet 2, resulting in high and uneven wind speed and high noise.
[0029] Furthermore, the area of the enclosed region 501 is larger than the area of the vent 6 , which helps to reduce wind speed and noise.
[0030] The center of the sound insulation board 5 and the center of the air flow inlet 1 are located on the same straight line, which is conducive to uniform wind speed and reduced noise.
[0031] The enclosed area 501 is concave inwardly toward the air inlet 1, forming an arc-shaped wall convex outwardly toward the air inlet 1, thereby reducing the impact of the air flow on the sound insulation board 5 and reducing noise. If the sound insulation board 5 is flat or concave inwardly toward the air outlet 2, the air flow will have a severe impact upon it, thereby increasing noise.
[0032] The thickness of the sound insulation board 5 is d, 1mm≤d≤10mm, which can not only play a certain role in reducing noise and wind speed, but also does not significantly increase the weight and cost of the product; when d>10mm, it will lead to increased product weight and increased cost; when d<1mm, the physical noise reduction effect is not obvious; preferably d=3mm.
[0033] The volume of the first chamber 7 is larger than that of the second chamber 8. The airflow velocity in the first chamber 7 is greater than that in the second chamber 8. The large volume of the first chamber 7 provides ample space for the airflow to achieve uniform velocity under the action of the heat insulation board, reducing noise. The smaller volume of the second chamber 8 allows the reduced-speed airflow to be discharged promptly, reducing air volume loss.
[0034] The fluffing nozzle also includes a filter 9, which is positioned across the airflow inlet 1. The airflow passes through the airflow inlet 1, the filter 9, the first chamber 7, and the second chamber 8 in sequence before being discharged from the airflow outlet 2. The distance between the filter 9 and the sound insulation board 5 is greater than the height of the second chamber 8. In this example, the filter 9 is a metal filter with numerous fine holes. It can be formed by various methods including machining, chemical etching, woven mesh, and plastic injection molding. The filter 9 initially reduces the air velocity, and the small holes have a good uniform effect on the airflow.
[0035] The fluffing nozzle also includes a housing 10 and a cover plate 11 connected to the housing 10. The air inlet 1 is provided on the cover plate 11. The housing 10 is mounted on the exterior of the deflector 3, forming a thermal insulation gap 12 between the two. The upper end of the deflector 3 abuts against the cover plate 11. The cover plate 11 is also provided with a plurality of comb teeth, each of which is provided with an air outlet 2. It can be understood that the deflector 3 is the outer shell of the nozzle, and the cover plate 11 is connected to the deflector 3.
[0036] The fluffing nozzle of the utility model is used in conjunction with a hair dryer product and can be detachably connected to the hair dryer by means of a snap fastener, a magnetic attraction, or the like.
[0037] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and these variations and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
