Description

Technical Field

[0001] The utility model relates to the technical field of products of air outlet accessories for hair dryers, in particular to a downwind air nozzle for hair dryers. Background Art

[0002] A hair dryer is a commonly used hair care appliance that can perform operations such as drying hair. However, when a single hair dryer is in use, wind is blown out directly from the air outlet. A hair dryer generally has only one large air outlet. When wind is blown out from the air outlet, the wind direction is poorly controllable, the wind force is uniformly crossed, and is blown out in a regional manner. Hair is easily messed up and easily blown onto the face, affecting the user's experience.

[0003] In order to meet different hairdressing needs, there are many hair styling accessories, such as wind hoods, flat mouths and hair combs. In a hair dryer comb, many comb teeth are connected to the outer surface of a base, a channel is provided inside the base, and air outlet holes are provided on its outer surface staggered with the comb teeth. The base is connected to the hair dryer so that the hot air output by the hair dryer is blown out from the air outlet holes through the channel, thereby achieving functions such as combing, drying and styling.

[0004] Prior art example 1, refer to patent document CN216019619U, relates to the technical field of hair care appliances, and in particular refers to an accessory for hair care appliances, including a shell, a plurality of comb teeth, soft rubber and a cover body, the shell is provided with a ventilation cavity, and a plurality of air outlets connected to the ventilation cavity; the comb teeth are arranged on the outer surface of the shell, and are staggered with the air outlets; the soft rubber is arranged between the comb teeth and the shell; the cover body presses the comb teeth and the soft rubber on the outer surface of the shell. Because the soft rubber has a buffering effect on the comb teeth, the comb teeth on the comb teeth can swing with the direction of the hair, and the layers of the hair can be adjusted more flexibly, and the scalp can be gently massaged. Example 1 has certain limitations during use, such as: 1. The air outlet is directly facing the outside, which is a linear air outlet with strong impact, which is easy to cause discomfort to the hair and skin; 2. The air outlet area is small; 3.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] Embodiment 1

[0043] Reference Figures 1 to 9A downwind air nozzle for a hair dryer comprises an air nozzle housing 1, an air inlet 11 and an air outlet 12 are provided on the air nozzle housing 1, and the air inlet 11 is connected to the air outlet 12 through an internal air duct;

[0044] The front end of the air nozzle housing 1 has a plurality of guide arc surfaces 2, and the air outlets 12 are distributed between adjacent guide arc surfaces 2;

[0045] The air outlet 12 is provided with shark fin-shaped support ribs 13, and the cross section of the air outlet 12 is in a closed shape with a larger back and a smaller front.

[0046] The above-mentioned basic structural scheme of the utility model is contained. Through the arrangement of the shark fin-shaped support ribs 13, firstly, a rigid support structure is provided between adjacent guide arc surfaces 2, so that the adjacent guide arc surfaces 2 have better structural stability and can withstand a certain external extrusion force and impact force without deformation, so as to ensure the stability of the shape of the air outlet 12; secondly, the shark fin-shaped support ribs 13 can also play a certain role in breaking wind and guiding flow, reduce the generation of turbulence, and make the air outlet more uniform and stable; thirdly, the shark fin-shaped support ribs 13 make the air outlet 12 present a specific shape (that is, the cross-section is a closed shape with a larger back and a smaller front), thereby having a guiding effect on the air outlet and forming an arc-shaped airflow 5. Once hair approaches, it will be quickly stuck in and close to the arc-shaped guide surface along the wind direction to prevent the hair from flying and being scattered, thereby obtaining a better user experience.

[0047] A preferred configuration of the basic structural scheme of the utility model is that the nozzle housing 1 is cylindrical, so a center point of the nozzle housing 1 is formed. The maximum distance between the air outlet 12 and the center point of the nozzle housing 1 is R1, and the maximum distance between the guide arc surface 2 and the center point of the nozzle housing 1 is R2, R2 ≥ R1. Thus, the guide arc surface 2 at least partially protrudes on the flow path of the arc-shaped airflow 5, so that the arc-shaped airflow 5 can be closely attached to the guide arc surface 2 and can continuously move along the guide arc surface 2.

[0048] Reference Figure 7 In some embodiments of the utility model, two auxiliary support ribs 14 are further provided at the air outlet 12, the shark fin-shaped support rib 13 is located in the middle of the air outlet 12, and the two auxiliary support ribs 14 are symmetrically arranged on both sides of the air outlet 12. The auxiliary support ribs 14 and the shark fin-shaped support ribs 13 are used in conjunction with each other to provide multi-point support, so that the air outlet 12 and the guide arc surface 2 are more stable. Furthermore, arc surface support ribs are further provided on both sides of the air nozzle housing 1, and the arc surface support ribs abut against the inner wall of the guide arc surface 2 to further improve the impact resistance of the guide arc surface 2 and the stability of the shape.

[0049] Embodiment 2

[0050] Based on the structure of the first embodiment, in order to obtain a more diverse use experience of the downwind nozzle, a functional structure is added, specifically: Figure 1-2 The nozzle housing 1 also has comb teeth 3. On the one hand, the arrangement of the comb teeth 3 adds various additional functions to the air outlet accessory of the present invention. First, it can play the role of combing hair; second, it can control the hair to prevent the hair from being scattered, so as to cooperate with the air outlet and achieve better hair blowing and hair care effects; third, it can form a certain gap between the hair and the hair, and between the hair and the skin, so that air can enter better, with a larger wind receiving area, and further improve the hair blowing and hair care effects.

[0051] Reference Figure 6 The preferred arrangement of the comb teeth 3 is that an assembly groove 15 is provided in the middle and lower part of the nozzle housing 1, and the inner end of the comb teeth 3 is detachably connected to the assembly groove 15, and a movement gap 151 is formed between the inner end of the comb teeth 3 and the assembly groove 15. By setting the movement gap 151, the body of the comb teeth 3 has an adaptive floating characteristic when in use. Specifically, when the body of the comb teeth 3 is locally subjected to pressure, the comb teeth 3 move inward; when the pressure is released, the comb teeth 3 can automatically reset under the action of gravity. As a result, the comb teeth 3 have functional characteristics similar to those of an air spring, thereby preventing the comb teeth 3 from making hard contact with the hair or skin, and improving the comfort of the body of the comb teeth 3.

[0052] Embodiment 3

[0053] Based on the structural scheme of the second embodiment, this embodiment provides a preferred implementation scheme for each guide arc surface 2, air outlet 12, and air outlet channel 16. Figures 4 to 6 , specifically:

[0054] The nozzle housing 1 is provided with a first air outlet channel 161, a second air outlet channel 162 and a third air outlet channel 163 which are separated from each other from the back to the front.

[0055] The guide arc surface 2 includes a first arc surface 21, a second arc surface 22 and a third arc surface 23;

[0056] The air outlet 12 includes a first air outlet 121, a second air outlet 122 and a third air outlet 123;

[0057] The first air outlet channel 161 is connected to the first air outlet 121, the first curved surface 21 is located outside the first air outlet channel 161, and the first air outlet 121 faces the second curved surface 22, so that the curved airflow 5 ejected from the first air outlet 121 flows along the second curved surface 22;

[0058] The second air outlet channel 162 is connected to the second air outlet 122, the second curved surface 22 is located outside the second air outlet channel 162, and the second air outlet 122 faces the third curved surface 23, so that the curved airflow 5 ejected from the second air outlet 122 flows along the third curved surface 23;

[0059] The third air outlet channel 163 is connected to the third air outlet 123 , the third arc surface 23 is located outside the third air outlet channel 163 , and the third air outlet 123 faces the comb teeth 3 , so that the arc airflow 5 ejected from the first air outlet 121 is ejected to the location of the comb teeth 3 .

[0060] In summary, the hair resting on the second curved surface 22, the third curved surface 23 and the comb teeth 3 can all obtain the hair drying and hair care effects of the curved airflow 5, with a larger hair drying area, and effectively prevent the hair from flying and being messy.

[0061] In order to achieve the split flow effect of the first air outlet 121, the second air outlet 122 and the third air outlet 123, the preferred structural mode is as follows: the air nozzle shell 1 is provided with an air inlet channel 17, and the side wall of the air nozzle shell 1 is provided with a split flow channel 18, and the split flow channel 18 is respectively connected to and connected with the air inlet channel 17, the first air outlet channel 161, the second air outlet channel 162 and the third air outlet channel 163. Preferably, the volume of the second air outlet channel 162 is greater than the volume of the first air outlet channel 161, and the volume of the first air outlet channel 161 is greater than the volume of the third air outlet channel 163. As a result, the air volume of the second air outlet 122 is the largest, followed by the first air outlet 121, and the air volume of the third air outlet 123 is the smallest.

[0062] The above structure limits the air volume to meet the needs of actual use. That is, when the user uses the downwind nozzle, the third curved surface 23 corresponds to the largest head volume, followed by the second curved surface 22, and finally the comb teeth 3, thereby obtaining better blowing and hair care effects.

[0063] Embodiment 4

[0064] Reference Figure 6 to Figure 9In this embodiment, the rear end of the nozzle shell 1 is also connected to an air inlet shell 4, and the air inlet shell 4 has an air inlet 41 and an air outlet 42. The air inlet 11 is connected to the air outlet 42 through an inverted cone-shaped converging air duct 43; the air outlet 42 is connected to and connected with the air inlet 11 of the nozzle shell 1. Among them, the air inlet shell 4 can be formed separately from the nozzle shell 1 and connected by assembly, or it can be formed in one piece, which is not particularly limited here. On the other hand, the air inlet 41 is connected to the hair dryer 6 to introduce airflow, and through the converging air duct 43, the air intake is pressurized and converged to increase the flow speed of the air, and then quickly flows into the air inlet 11 of the nozzle shell 1 through the air outlet 42.

[0065] Preferably, a magnetic ring 44 is provided at the rear end of the air inlet shell 4, and a magnetic part corresponding to the magnetic ring 44 is also provided at one end of the hair dryer 6, so as to realize a quick and detachable connection between the air inlet shell 4 (downwind air nozzle) and the hair dryer 6.

[0066] It is worth noting that other technical solutions of the present invention belong to the prior art and will not be described in detail.

[0067] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
