Description

Technical Field

[0001] This utility model relates to the field of hair styling accessories technology, and in particular to a negative pressure suction type hair curling accessory and hair styling device. Background Technology

[0002] In related technologies, such as the Chinese utility model patent CN222968101U, a hair dryer with a curling iron accessory and the hair dryer using the same accessory is disclosed. Each air outlet channel of each air outlet array is connected to the trough between adjacent wavy arc surfaces on the outer side of the curling iron body, and an arc-shaped recessed air outlet is formed at the trough.

[0003] During actual research and development, the inventors discovered that this hair curling accessory (hair curling attachment) is limited by the influence of two adjacent wavy arc surface structures. As a result, when the air outlet channel is located at the trough between the two adjacent wavy arc surfaces, most of the airflow blown out by the air outlet channel cannot flow along the curved surface. As a result, less airflow is generated along the arc surface, making it difficult to form an effective and uniform adsorption force. Most of the hair may be blown away rather than adsorbed.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide a negative pressure suction hair curling attachment, which effectively solves the technical defect in the existing hair curling attachment that is difficult to form an effective and uniform adsorption force.

[0006] This utility model provides a negative pressure suction hair curling accessory, including...

[0007] stent; and,

[0009] Each arc-shaped wall of the outer cylinder includes a high point end and a low point end. The high point end and the low point end between two adjacent arc-shaped walls do not overlap. The high point end and the low point end between two adjacent arc-shaped walls are connected by a connecting wall.

[0010] The connecting wall is provided with a first air outlet along the first axis, and the bracket is provided with a second air outlet along the second axis. The second air outlet can blow airflow through the first air outlet to the outer arc surface of the arc wall. The size of the first air outlet is larger than the size of the second air outlet, and the second axis is inclined to the side of the outer arc surface to form a first angle with the first axis.

[0011] The beneficial effects of the negative pressure suction hair curling attachment provided by this utility model are as follows: Compared with the prior art, firstly, by connecting the high and low points of two adjacent arc-shaped walls through a connecting wall, and setting a first air outlet along the first axis on the connecting wall, and setting a second air outlet along the second axis on the bracket, since the second axis is inclined towards the outer arc surface, the airflow blown out from the second air outlet can be blown out along the tangential direction or close to the tangential direction of the outer arc surface. The airflow can be consciously guided to flow out along the outer arc surface, thus forming a continuous and relatively stable low-pressure area (negative pressure area); by actively guiding the blown airflow, the kinetic energy of the airflow can be converted into the energy required to generate the low-pressure area more efficiently, which can further enhance the adsorption force of the low-pressure area, thereby achieving a more reliable suction effect.

[0012] Secondly, the connecting wall provides a stable, regular, and easy-to-manufacture airflow platform; it also makes it easier to control the airflow angle of the first and second air outlets, allowing the airflow to flow out close to the outer arc surface at a relatively high speed, concentrated, stable, and directional controlled airflow velocity, and reliably and stably attach to the outer arc surface to generate a strong and uniform adsorption force.

[0013] As a preferred embodiment, the support consists of multiple support walls forming a ring-shaped structure, with adjacent support walls connected by a support section.

[0014] The inner surface of the arc-shaped wall abuts against the outer surface of the supporting wall, the inner surface of the connecting wall abuts against the outer surface of the supporting part, and the first air outlet penetrates the inner and outer surfaces of the supporting part.

[0015] As a preferred embodiment, the support frame is surrounded by multiple support walls forming an air cavity. The support frame has a first air inlet at its axial end, and the first air inlet and the first air outlet are connected to the air cavity.

[0016] As a preferred embodiment, the bracket has a connecting cover at one end of the first air inlet and an end cover at the other end away from the first air inlet; when the outer cylinder is fitted onto the outer surface of the bracket, the outer cylinder can be confined between the connecting cover and the end cover.

[0017] As a preferred option, the first air outlet is any one of a circular hole, an elliptical hole, an elongated hole, or an irregularly shaped hole;

[0018] The second air outlet can be any of the following: a round hole, an oval hole, a long strip hole, or an irregularly shaped hole.

[0019] As a preferred embodiment, both the first air outlet and the second air outlet are elongated outlets, and the vertical direction of the first air outlet is defined as the first height, and the vertical direction of the second air outlet is defined as the second height.

[0020] The second height of the second air outlet is less than the first height of the first air outlet, so that the bracket has a first shielding part covering the upper side of the first air outlet and a second shielding part covering the lower side of the first air outlet.

[0021] As a preferred embodiment, the upper and lower sides of the first air outlet are arranged parallel to the first axis, and the upper and lower sides of the second air outlet are arranged parallel to the second axis.

[0022] The distance between the upper surface of the first air outlet and the upper surface of the second air outlet is the first width, and the distance between the lower surface of the first air outlet and the lower surface of the second air outlet is the second width. The first width is greater than the second width.

[0023] As a preferred option, the first angle is 12 degrees;

[0024] The second axis and the outer arc surface form a second angle, which is 15 degrees.

[0025] As a preferred embodiment, a third axis and a fourth axis are defined to extend radially along the outer cylinder, and the third axis and the fourth axis form a third angle, which is 59 degrees.

[0026] The first and second air outlets output airflow to the lowest point of the arc-shaped wall. The second axis of the second air outlet forms a fourth angle with the fourth axis of the arc-shaped wall, which is 8 degrees.

[0027] This utility model also provides a hair styling device, which is equipped with a negative pressure suction curling attachment. Compared with the prior art, by installing the negative pressure suction curling attachment into the hair styling device, the hair styling device provides airflow into the negative pressure suction curling attachment. The airflow can be blown out towards the lowest point of the arc-shaped wall through the second air outlet and the first air outlet, and a low-pressure area is generated on the outer arc surface of the arc-shaped wall. When the user brings the hair close to the negative pressure suction curling attachment, the low-pressure area can be used to attract the hair and assist the user in styling the hair.

[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0047] Please refer to the following: Figures 1 to 8 The negative pressure suction hair curling accessory 100 provided in the embodiments of this application will now be described. The negative pressure suction hair curling accessory 100 includes a bracket 10 and an outer cylinder 20.

[0048] The outer cylinder 20 is formed by multiple arc-shaped walls 21 to form a ring structure. The bracket 10 can be inserted into the outer cylinder 20 so that the outer cylinder 20 is fitted onto the outer surface of the bracket 10. Each arc-shaped wall 21 of the outer cylinder 20 includes a high point end 211 and a low point end 212. The high point end 211 and the low point end 212 between two adjacent arc-shaped walls 21 do not overlap. The high point end 211 and the low point end 212 between two adjacent arc-shaped walls 21 are connected by a connecting wall 22. The connecting wall 22 has a first air outlet 23 along the first axis s1, and the bracket 10 has a second air outlet 13 along the second axis s2. The second air outlet 13 can blow airflow through the first air outlet 23 onto the outer arc surface 213 of the arc-shaped wall 21. The size of the first air outlet 23 is larger than the size of the second air outlet 13, and the second axis s2 is inclined towards the outer arc surface 213 to form a first angle α1 with the first axis s1.

[0049] Specifically, in the first aspect, the high point 211 and low point 212 of two adjacent arc-shaped walls 21 are connected by a connecting wall 22, and a first air outlet 23 is set on the connecting wall 22 along the first axis s1, and a second air outlet 13 is set on the bracket 10 along the second axis s2. Since the second axis s2 is inclined towards the outer arc surface 213, the airflow blown out from the second air outlet 13 can be blown out along the tangential direction or close to the tangential direction of the outer arc surface 213. The airflow can be consciously guided to flow out along the outer arc surface 213, thus forming a continuous and relatively stable low-pressure area (negative pressure area); for the blown out The airflow is actively guided, which can more efficiently convert the kinetic energy of the airflow into the energy required to generate a low-pressure area, and further enhance the adsorption force of the low-pressure area, thereby achieving a more reliable air suction effect. Secondly, the connecting wall 22 can provide a stable, regular and easy-to-manufacture airflow emission platform. Moreover, it can more easily control the air outlet angle of the first air outlet 23 and the second air outlet 13, so that the airflow can flow out closely to the outer arc surface 213 at a relatively high speed, concentrated, stable and directional controlled airflow speed, and can reliably and stably adhere to the outer arc surface 213 to generate a strong and uniform adsorption force.

[0050] In some embodiments, the bracket 10 is formed by a plurality of support walls 11 forming a ring structure, and two adjacent support walls 11 are connected by a support portion 12; the inner surface of the arc-shaped wall 21 abuts against the outer surface of the support wall 11, the inner surface of the connecting wall 22 abuts against the outer surface of the support portion 12, and the first air outlet 23 penetrates the inner and outer surfaces of the support portion 12.

[0051] Specifically, the support 10 is surrounded by multiple support walls 11 forming an air cavity 14. The support 10 has a first air inlet 15 at its axial end, and the first air inlet 15 and the first air outlet 23 are connected to the air cavity 14. The support 10 has a connecting cover 16 at one end of the first air inlet 15 and an end cover 17 at the other end facing away from the first air inlet 15. When the outer cylinder 20 is fitted onto the outer surface of the support 10, the outer cylinder 20 is confined between the connecting cover 16 and the end cover 17. Preferably, the outer or inner surface of the connecting cover 16 has a latching protrusion structure or a latching groove structure, which is used to fasten and connect with the air outlet of the hair styling device.

[0052] More specifically, the bracket 10 and the outer cylinder 20 can be manufactured by injection molding or die casting. The first air outlet 23 is formed on the connecting wall 22 by stamping or milling, and the second air outlet 13 is formed on the support part 12 by stamping or milling. The connecting wall 22 and the support part 12 provide effective support during the processing of the first air outlet 23 and the second air outlet 13, so that the shape of the arc wall 21 and the support wall 11 will not be changed during the processing of the first air outlet 23 and the second air outlet 13, thereby improving the production yield.

[0053] Preferably, the support part 12 is provided with a plurality of clearance windows 110 arranged at axial intervals. The clearance windows 110 can reduce the material consumption of the bracket 10 and reduce the overall weight of the bracket 10. After the outer cylinder 20 is installed on the bracket 10, these clearance windows 110 are completely covered by the arc-shaped wall 21 and do not bear any air outlet effect.

[0054] In other embodiments, the first air outlet 23 is any one of a circular hole, an elliptical hole, an elongated hole, or an irregularly shaped hole; the second air outlet 13 is any one of a circular hole, an elliptical hole, an elongated hole, or an irregularly shaped hole. The shapes of these first air outlets 23 and second air outlets 13 can be changed as needed according to actual production or usage requirements, but it is best to position the first air outlet 23 and the second air outlet 13 to have the same shape, only requiring that the size of the first air outlet 23 is larger than the size of the second air outlet 13.

[0055] Specifically, both the first air outlet 23 and the second air outlet 13 are elongated outlets. The vertical direction of the first air outlet 23 is defined as the first height h1, and the vertical direction of the second air outlet 13 is defined as the second height h2. The second height h2 of the second air outlet 13 is less than the first height h1 of the first air outlet 23, so that the bracket 10 has a first shielding part 18 covering the upper side of the first air outlet 23 and a second shielding part 19 covering the lower side of the first air outlet 23. By setting the second air outlet 13, which is smaller than the first air outlet 23, the speed of airflow can be accelerated by using the smaller second air outlet 13, and the larger first air outlet 23 can provide better clearance for the second air outlet 13 to blow air toward the curved wall 21, so that the second air outlet 13 is closer to the curved wall 21.

[0056] More specifically, the upper and lower sides of the first air outlet 23 are arranged parallel to the first axis s1, and the upper and lower sides of the second air outlet 13 are arranged parallel to the second axis s2. The distance between the upper surface of the first air outlet 23 and the upper surface of the second air outlet 13 is a first width w1, and the distance between the lower surface of the first air outlet 23 and the lower surface of the second air outlet 13 is a second width w2, where the first width w1 is greater than the second width w2. This structure allows for further adjustment of the second air outlet 13 to blow air closer to the side of the curved wall 21.

[0057] Preferably, the first angle a1 is 12 degrees; the second axis s2 and the outer arc surface 213 form a second angle a2, which is 15 degrees. A third axis s3 and a fourth axis s4 are defined extending radially along the outer cylinder 20, and the third axis s3 and the fourth axis s4 form a third angle a3, which is 59 degrees; the first air outlet 23 and the second air outlet 13 output airflow to the lowest point 212 of the arc-shaped wall 21, and the second axis s2 of the second air outlet 13 and the fourth axis s4 of the arc-shaped wall 21 form a fourth angle a4, which is 8 degrees.

[0058] It should be noted that the aforementioned first angle a1, second angle a2, third angle a3, and fourth angle a4 are set to rationally arrange the specific positions of the first air outlet 23 and the second air outlet 13, providing a stable, regular, and easily manufactured airflow emission structure. This optimizes the flow field of the airflow from the first air outlet 23 and the second air outlet 13, reduces turbulence, and makes the airflow direction more controllable, creating a state more conducive to stable adhesion of the Coanda effect. Moreover, setting the second axis s2 of the second air outlet 13 and the fourth axis s4 of the corresponding highest point of the arc-shaped wall 21 to a small value of 8 degrees allows the second air outlet 13 and the air cavity 14 to blow air in a nearly parallel manner, making the airflow path area tend to flow in the same direction, suppressing turbulence generation, and improving the stability of the airflow.

[0059] In other embodiments, a hair styling device is also provided, which is a hair dryer or a curling iron. The negative pressure suction curling attachment 100 is installed at the air outlet of the hair styling device, which can provide airflow. The airflow flows into the air cavity 14 from the first air inlet, and then blows out from the second air outlet 13 and the first air outlet 23 toward the low end 212 of the arc-shaped wall 21. A low-pressure area is generated on the outer arc surface 213 of the arc-shaped wall 21. When the user brings the hair close to the negative pressure suction curling attachment 100, the low-pressure area can be used to attract the hair and assist the user in styling the hair.

[0060] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
