[0002] As the quality of life improves, people's requirements for their own aesthetics also increase. Hair style, as one of the main external manifestations of appearance beauty, is often valued by people. In daily life, people usually use hair straighteners to straighten their hair. Traditional hair straighteners usually include upper and lower clamps that work together. The opposite sides of the clamps are provided with heating plates. By driving the clamps, the heating plates clamp the hair, causing the hair to be heated and straightened, thereby achieving a straightening effect.

[0003] However, the high temperature of the heating plate can easily burn the hair, and people holding the hair straightener can easily accidentally touch the heating plate and cause burns. At the same time, people usually need to wash their hair or wet their hair before styling to facilitate styling. However, wet hair cannot be straightened immediately and needs to be blow-dried. Therefore, the use of hair straighteners makes the hair styling process cumbersome and is not conducive to people's quick hair styling. Utility Model Content

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0038] like Figure 1-5 As shown, the utility model provides a three-air ventilator, comprising a hollow main body 1, one end of the main body 1 being an air inlet 11 for detachably connecting to a hair dryer (not shown), and the other end being provided with two clamping plates 2 symmetrically arranged up and down, each of the clamping plates 2 being provided with an air guide cavity 21, a styling cavity 3 for clamping hair being provided between the two clamping plates 2, a styling surface 22 for contacting hair being provided on one side of the clamping plate 2 close to the styling cavity 3, an air outlet 23 being provided on the styling surface 22, the air guide cavity 21 being in communication with the air inlet 11 and the air outlet 23 respectively; wherein the air outlet direction of the air outlet 23 is parallel to or intersecting with the styling surface 22;

[0039] When in use, the airflow generated by the hair dryer enters the interior of the main body 1 from the air inlet 11, and then passes through the air guide cavity 21 and the air outlet 23 in the clamping plate 2 to be discharged into the styling cavity 3, thereby drying and straightening the hair in the styling cavity 3; at this time, since the styling surface 22 is a planar structure, the styling surface 22 has the effect of flattening and straightening the hair when clamping it, and under the action of the airflow discharged from the air outlet 23, the hair is dried while being straightened; when the hair dryer blows out hot air, it can also straighten the hair, thereby achieving a better straightening effect.

[0040] Specifically, such as Figure 3-4As shown, an angled air guide portion 12 is provided in the main body 1 and at the connection point of the splint 2, the air guide portion 12 includes two air guide surfaces 121 symmetrically arranged up and down, the two air guide surfaces 121 are intersected and connected at one end close to the air inlet 11, and the other ends correspond to the two splints 2 one by one; the end of the air guide surface 121 away from the air inlet 11 extends toward the splint 2 corresponding thereto, and is fixedly connected to the styling surface 22; after the air flow enters the main body 1, it flows into the air guide cavity 21 of the splint 2 under the air guiding action of the air guide portion 12, and under the action of the air guide portion 12 and the air guide surface 121, the convection of the air flow in the main body 1 can be effectively reduced, thereby increasing the flow rate and flow speed of the air flow, thereby achieving a better air outlet effect;

[0041] Preferably, the air guide surface 121 can be a flat structure or a curved structure. On the premise that the outer surface of the air guide surface 121 is sufficiently smooth, both the flat structure and the curved structure can effectively improve the air outlet effect of the air outlet 23.

[0042] Further, if Figure 1 As shown in Figure 3, in order to make the air nozzle lighter and save materials to reduce production costs, a through hole 122 is provided in the air guide portion 12 and between the two air guide surfaces 121, and both ends of the through hole 122 extend toward the peripheral wall of the main body 1 and pass through the main body 1; through the provision of the through hole 122, while the air guide portion 12 has a good air guiding effect, the manufacturing material of the air nozzle can be further reduced, thereby making the air nozzle lighter and more practical.

[0043] Specifically, such as Figure 14 As shown, the shaping surface 22 includes a shaping first half surface 221 and a shaping second half surface 222 .

[0044] In order to further illustrate the technical solution of the present utility model, two embodiments are provided below;

[0045] In the first embodiment, as Figure 5 As shown, the air outlet 23 is arranged on a side close to the molding surface 22 (combined with Figure 14 and Figure 15As shown, the air outlet 23 is mainly arranged on the first half surface 221 of the molding relative to the second half surface 222 of the molding). At least one longitudinal air guide plate 231 is further provided in the air outlet 23. The longitudinal air guide plate 231 extends along the length direction of the air outlet 23 and is inclined toward the other side of the molding surface 22 so that the air flow is ejected toward the other side of the molding surface 22. At least one transverse air guide plate 232 is provided in the air outlet 23. The extension directions of the longitudinal air guide plate 231 and the transverse air guide plate 232 are perpendicular to each other. By providing the longitudinal air guide plates 231 and the transverse air guide plates 232, the air outlet 23 is divided into several parts to form grilles, so that the air outlet 23 is more uniform, thereby avoiding the problem of large air volume at one end of the air outlet 23 and small air volume at the other end, thereby improving the consumer's user experience.

[0046] Further, if Figure 6 As shown, the longitudinal air guide plate 231 is tilted along the axis P, and the axis P forms an angle A with the styling surface 22. The angle A is an acute angle less than 90 degrees, preferably an acute angle of 15 to 60 degrees. The tilted longitudinal air guide plate 231 allows the airflow entering the styling cavity 3 to flow in the same direction to reduce airflow counter-flow, thereby improving air outlet efficiency, as well as hair drying and straightening efficiency.

[0047] Furthermore, in order to synchronize the air outlet directions of the two clamping plates 2, the longitudinal air guide plates 231 and the transverse air guide plates 232 in the two clamping plates 2 are symmetrically arranged in a vertical direction, so that the air discharged from the air outlets 23 corresponding to the two clamping plates 2 can flow in the same direction, further improving the air outlet effect of the air nozzle and increasing the wind pressure, which is more conducive to drying, softening and smoothing the hair.

[0048] Preferably, one end of each of the longitudinal air guide plate 231 and the transverse air guide plate 232 is flush with the molding surface 22, and the other end thereof extends into the air guide cavity 21 to form an air induction portion 233. The air induction portion 233 effectively guides the airflow to various positions of the air outlet 23, thereby further improving the uniform air discharge effect of the air outlet 23.

[0049] More preferably, if Figure 6-7As shown, the distance between the two styling surfaces 22 gradually increases toward the air outlet direction, so that the styling cavity 3 has a trumpet-shaped structure. Due to the trumpet-shaped arrangement of the styling cavity 3, the side with a smaller distance in the styling cavity 3 can relatively clamp the hair, while the side with a larger distance provides more swinging space for the hair, thereby increasing the distance between the hairs. Under the action of the airflow, the hair strands spread out from each other, effectively increasing the contact area between the airflow and each hair strand, thereby achieving a faster drying effect. At the same time, it is beneficial for the sliding in and out of the hair bundles, and also encourages the airflow to be discharged toward the side with the larger opening, reducing the backflow toward the side with the smaller opening (when too much hair slides into the styling cavity 3, a portion of the airflow will backflow toward the side with the smaller opening).

[0050] In the second embodiment, as Figure 8 As shown, the air outlet 23 is arranged on the styling surface 22 at one side close to the outer peripheral wall 24 of the clamping plate 2, and the outer peripheral wall 24 of the clamping plate 2 corresponding to the air outlet 23 is provided with an arc plate 25 that bends and extends toward the styling cavity 3, and the arc plate 25 overlaps with at least a portion of the styling surface 22 to form a gap 4, and the gap 4 is connected to the air outlet 23 and the styling cavity 3 respectively; through the arrangement of the arc plate 25 and the gap 4, the air flow is guided by the arc plate 25 in a direction parallel to the styling surface 22 or the air flow is blown out for a distance and then intersects with the styling surface 22, thereby increasing the contact area between the air flow and the hair in the styling cavity 3, and the air outlet 23 is arranged in the styling cavity 3 to increase or maintain the wind pressure of the air flow, thereby improving the drying and straightening effect on the hair, so as to improve the consumer's use experience;

[0051] Further, if Figure 9 As shown, in order to improve the uniformity of the air outlet 23 and avoid the problem of large air volume at one end of the air outlet 23 and small air volume at the other end, at least one transverse air guide plate 232 is provided at the air outlet 23, one end of the transverse air guide plate 232 extends into the gap 4, and the other end extends into the air guide cavity 21 to form an air induction portion 233, and the transverse air guide plates 232 are arranged perpendicular to the extension direction of the styling surface 22 and the air outlet 23; through the arrangement of the transverse air guide plates 232, the air outlet paths formed by the air outlet 23 and the gap 4 are separated from each other, and at the same time, through the arrangement of the air induction portion 233, the air flow is effectively guided into each of the air outlets 23, thereby improving the uniformity of the air outlet 23;

[0052] Preferably, in the second embodiment, there are multiple transverse air guide plates 232 , and the multiple transverse air guide plates 232 are arranged at equal intervals.

[0053] Specifically, such as Figure 10As shown, the outer peripheral wall 24 of the clamping plate 2 is in an arc-shaped structure. When in use, consumers can wrap their hair around one or two clamping plates 2 and blow air to the hair while fixing it or blowing air while pulling it, so that the hair can be dried quickly. At the same time, due to the arc-shaped design of the outer peripheral wall 24, the hair is in a curved state when wrapped around the clamping plate 2. Therefore, under the combined effect of the arc-shaped surface and the airflow, consumers can achieve a curly hairdressing effect.

[0054] Further, if Figure 11 As shown, a plurality of comb teeth 5 are further provided on the side of the outer peripheral wall 24 of the clamping plate 2 away from the styling surface 22, and the comb teeth 5 are arranged at intervals along the length direction of the clamping plate 2; through the arrangement of the comb teeth 5, the hair wrapped around the clamping plate 2 is straightened and fixed in position, preventing the curled hair from escaping from the clamping plate 2 due to its own elastic force during the hairdressing or drying process, thereby effectively improving the consumer's usage experience.

[0055] Specifically, such as Figure 2 As shown, the main body 1 is provided with a plurality of inner connecting parts 13 on the inner wall near the air inlet 11, and a plurality of outer snap-in grooves 14 on the outer wall. When the main body 1 is connected to the hair dryer, the inner and outer synchronous snap-in connections with the hair dryer are achieved through the inner connecting parts 13 and the outer snap-in grooves 14, thereby achieving a stable connection between the main body 1 and the hair dryer, thereby avoiding the problem of the main body 1 falling off due to excessive wind force from the hair dryer;

[0056] Furthermore, the inner connecting member 13 and the outer snap-fitting groove 14 on the main body 1 are respectively provided at corresponding inner and outer positions on the inner wall and outer wall of the main body 1 , thereby effectively improving the snap-fitting firmness between the main body 1 and the hair dryer.

[0057] Furthermore, the arrangement of the comb teeth 5 needs to be further elaborated. Figures 12 to 17 As shown, the molding surface 22 includes a molding first half surface 221 and a molding second half surface 222, and the peripheral wall 24 includes a peripheral first wall surface 241 and a peripheral second wall surface 242. The peripheral second wall surface 242 and the molding second half surface 222 are smoothly connected by a second arc-shaped sliding surface 224, and the peripheral first wall surface 241 and the molding first half surface 221 are smoothly connected by a first arc-shaped sliding surface 223. The multiple surfaces form a smooth longitudinal peripheral surface around the single splint 2;

[0058] Two V-shaped duckbill arc sliding surfaces 243 are provided on the end surfaces of the upper and lower clamping plates 2. When clamping hair, the hair can slide along the duckbill arc sliding surfaces 243 into the styling cavity 3, thereby reducing friction damage to the hair.

[0059] Specifically, a hair blocking surface 244 is provided between the upper and lower clamping plates 2 and on one side of the styling cavity 3. However, when clamping hair, more hair may be concentrated on one end of the styling cavity 3 near the hair blocking surface 244. To this end, comb teeth 5 may be added to the longitudinal outer surface of the clamping plate 2 to evenly isolate the distribution of hair.

[0060] Further, if Figure 12 As shown, the comb teeth 5 are arranged on the first arc sliding surface 223, the first styling half surface 221, the second styling half surface 222 or the second arc sliding surface 224. When the hair is clamped in the styling cavity 3, the arrangement of the comb teeth 5 prevents the hair from sliding onto the hair blocking surface 244, thereby ensuring that more hair is arranged at the air outlet 23, thereby increasing the contact area between the hair and the airflow;

[0061] Preferably, the comb teeth 5 are arranged on the first peripheral wall 241 and / or the second peripheral wall 242 for better effect, as shown in the following example: Figure 16 and Figure 17 As shown, when the hair slides into the styling cavity 3 and then rotates and moves the clamping plate 2 along the length direction of the hair, since the hair roots are fixed to the scalp and the hair ends are free ends, the clamping plate 2 can move along the hair toward the hair ends, so as to achieve uniform hot air care for all parts of the hair between the comb teeth 5;

[0062] More preferably, the comb teeth 5 are arranged on the first peripheral wall 241 for the best effect.

[0063] The following is a detailed description of the working principle of the utility model;

[0064] When in use, the nozzle is first connected to the hair dryer, and then the hair dryer is turned on to drive the air flow through the air inlet 11, the air guide cavity 21 and the air outlet 23 in sequence to be discharged into the styling cavity 3; at this time, the consumer clamps the hair in the styling cavity 3, and the air flow blown out from the air outlet 23 on the upper and lower clamping plates 2 acts on the upper and lower end surfaces of the hair at the same time and is blown out in the direction of the hair, thereby achieving the effect of straightening and drying the hair;

[0065] When curling is required, the hair is wrapped around a single clamping plate 2 and covered with the air outlet 23. The hair dryer is adjusted to the hot air state. The hair is fixed or pulled for blowing, and the hot air and the arc surface design of the peripheral wall 24 are used to make the hair have a curly and fixed hairdressing effect.

[0066] The innovation of the present invention lies in that air outlets are provided on the upper and lower end surfaces of the styling cavity, and the air outlet direction is parallel to or intersecting with the hair clamped in the styling cavity, so that the hair can achieve a straight and dry hairdressing effect; at the same time, through the arrangement of the curved outer peripheral wall of the clamping plate and the comb teeth, consumers can use the same air nozzle to achieve the curling operation, and the air nozzle has an integrated design, a simple structure, and is convenient and durable.
