Description

Technical Field

[0001] This invention relates to a hair styling tool. Background Technology

[0002] In the prior art, such as Chinese patent application CN202280043774.5, published on February 6, 2024, a hair styling tool is disclosed, comprising: a first arm and a second arm connected together for reciprocating movement toward and away from each other, and arranged to receive hair in an area between them; an air collection chamber disposed within at least one of the first and second arms, the air collection chamber including an air inlet for receiving airflow from a fan unit and an air outlet for discharging airflow into the area; and at least one air deflector disposed along at least one of the first and second arms, the air deflector being configured to deflect at least some of the airflow out of the area. In the above solution, the high-speed airflow is deflected again by the external air deflector into the side blowing channel, and then discharged through the side air outlet; in this process, since both the side airflow and the styling airflow are separated and deflected after passing through the styling area, their temperatures are close, so a temperature difference for styling cannot be generated. The first and second arms must be closed during use, resulting in poor performance and inconvenience. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a new type of straightening and shaping clamp that can achieve both shaping and shaping functions with good results.

[0004] According to the present invention, a novel straightening and shaping clamp includes two relatively openable long arms. A shaping panel is provided at the relative position of the two long arms, and a shaping air outlet is provided on the shaping panel. A shaping air outlet is provided on the side of at least one of the long arms. A heating frame is provided in the inner cavity of the long arm. Two independent shaping air ducts and shaping air ducts are provided in the inner cavity of the long arm. The shaping air ducts are connected to the shaping air outlets, and the shaping air ducts are connected to the shaping air outlets. The heating frame is located in the shaping air ducts.

[0005] The novel straightening and shaping clamp provided by the present invention also has the following auxiliary technical features: Further, an airflow distributor is provided in the inner cavity of the long arm, which divides the airflow in the inner cavity of the long arm into a shaping airflow and a setting airflow. The shaping airflow enters the shaping air duct, and the setting airflow enters the setting air duct.

[0006] Further, the temperature of the shaping air outlet is lower than the temperature of the styling air outlet, and the wind speed of the shaping air outlet is lower than the wind speed of the styling air outlet.

[0007] Further, an air inlet is provided at one end of the inner cavity of the long arm, most of the high-speed airflow from the air inlet flows into the shaping air duct, and a small portion of the high-speed airflow from the air inlet flows into the sizing air duct.

[0008] Furthermore, the airflow volume of the shaped air outlet is Q. 造 The shaped air volume of the shaped air outlet is Q. 定 If the total air volume inside the long arm is Q, then: , where a and b are proportionality constants, and a+b=1, the value of a ranges from 0.6 to 0.7, and the value of b ranges from 0.3 to 0.4.

[0009] Furthermore, the design temperature of the air outlet is T. 造 The shaping temperature of the shaping air outlet is T. 定 Then: T=T 造 -T 定 Where T is the temperature difference for shaping, and the value of T ranges from 50 degrees to 80 degrees.

[0010] Further, the airflow distributor covers the shaped air duct, and the airflow distributor is provided with a plurality of through holes, which communicate with the shaped air outlet.

[0011] Furthermore, the air duct is equipped with an airflow deflection structure.

[0012] Furthermore, a flow-dividing and mixing space is provided between the airflow distributor and the shaped air outlet.

[0013] Furthermore, one end of the shaped air duct has an air inlet gap, which communicates with the air inlet.

[0014] The novel hair straightening and styling tool provided by this invention has the following advantages compared with the prior art: This invention divides high-speed airflow into two parts within the inner cavity of the long arm; one part is introduced into the styling air outlet, and the other part is introduced into the styling air outlet, thereby achieving hair styling and setting. The styling blower of this invention is not affected by the state of the long arm, making it more convenient to use and providing better styling results. Attached Figure Description

[0022] To clearly illustrate the solutions in this invention, preferred embodiments are given below in conjunction with the accompanying drawings. The following description is merely exemplary and not intended to limit the application or use of this disclosure. It should be understood that throughout the drawings, corresponding reference numerals denote the same or corresponding parts and features.

[0023] See Figures 1 to 7 The present invention provides a novel straightening and shaping clamp, comprising two opposing opening and closing long arms 1 and 2. A shaping panel 3 is positioned opposite each other on the two long arms 1 and 2, and a shaping air outlet 4 is provided on the shaping panel 3. At least one of the long arms 1 has a shaping air outlet 5 on its side. A heating frame 6 is provided in the inner cavity 61 of the long arm 1. Two independent shaping air ducts 9 and shaping air ducts 7 are provided in the inner cavity of the long arm 1. The shaping air ducts 9 communicate with the shaping air outlet 4, and the shaping air ducts 7 communicate with the shaping air outlet 5. The heating frame 6 is located in the shaping air duct 9. The long arms in this invention include a first long arm 1 and a second long arm 2. The shaping air outlet 5 and the shaping air duct 7 can be located in the first long arm 1 or the second long arm 2, or both long arms can have them. This invention relates to a hair styling and setting tool. The heating element 6 is equipped with a heating component that generates high temperatures. High-speed external airflow is blown into the inner cavity 61, heating the external high-speed airflow into a high-temperature, high-speed airflow to straighten and shape the hair. With the addition of a styling air outlet 4 and a setting air outlet 5, this invention achieves both styling and setting functions, making it convenient to operate. This invention features two independent high-speed air ducts: one for styling and the other for setting. These two independent air ducts allow for adjustment of the airflow volume to regulate the temperature of the setting air outlet, resulting in better hair styling and setting effects.

[0024] See Figures 1 to 7In the above embodiments provided by the present invention, an airflow distributor 8 is further provided in the inner cavity of the long arm 1. The airflow distributor 8 divides the airflow in the inner cavity of the long arm 1 into a shaping airflow and a setting airflow. The shaping airflow enters the shaping air duct 9, and the setting airflow enters the setting air duct 7. In the present invention, the airflow distributor 8 divides a portion of the shaping airflow into the setting air duct 7, so that the shaping airflow and the setting airflow are divided into two paths in the inner cavity and flow independently. At this time, the temperature of the setting airflow can be controlled to achieve the optimal setting effect. Figure 5 The middle arrow indicates the direction of airflow in the design. Figure 6 The arrows in the diagram indicate the direction of flow of the shaped airflow.

[0025] See Figures 1 to 7 In the above embodiments provided by the present invention, the temperature of the shaping air outlet 5 is lower than the temperature of the styling air outlet 4, and the wind speed of the shaping air outlet 5 is lower than the wind speed of the styling air outlet 4. According to the principle of fluid flow continuity, the flow rate is the same at any position in a flow tube; and the flow rate Q = S (cross-sectional area) x velocity V. Based on this principle, we can change the size of the cross-sectional area to obtain the desired velocity. According to Bernoulli's principle, the fundamental logic of the desired flow velocity and flow rate is still mechanical energy. In our structure, this mechanical energy is the kinetic energy of the fluid, kinetic energy = 1 / 2 mass × velocity squared. Thus, by adjusting the distribution ratio of the shaping flow rate and the styling flow rate through the structure, and by changing different cross-sectional areas S, we obtain the desired flow velocity V, thereby achieving the required shaping flow velocity and styling flow velocity.

[0026] See Figures 1 to 7 In the above embodiments provided by the present invention, an air inlet 62 is provided at one end of the inner cavity 61 of the first long arm 1 and the second long arm 2. Most of the high-speed airflow from the air inlet 62 flows into the shaping air duct 9, and a small portion of the high-speed airflow from the air inlet 62 flows into the setting air duct 7. The heating frame 6 faces the air inlet 62, and most of the high-speed airflow entering from the air inlet 62 can enter the heating frame 6, thereby heating most of the high-speed airflow. A small portion of the high-speed airflow enters the setting air duct 7 as a normal-temperature high-speed airflow, creating a temperature difference between the high-speed airflow blown out by the setting air outlet 5 and the high-speed airflow blown out by the shaping air outlet 4, thereby achieving the purpose of setting.

[0027] See Figures 1 to 7In the above embodiments provided by the present invention, the airflow distributor 8 is further included, covering the shaping air duct 7. The airflow distributor 8 is provided with a plurality of through holes 81, which communicate with the shaping air outlet 5. The airflow distributor 8 can block the airflow in the shaping air duct 7, allowing a small portion of the airflow to pass through the through holes 81 as shaping airflow. In addition, the airflow distributor 8 can make the airflow blown out of the shaping air outlet 5 more uniform. The airflow distributor 8 can retain most of the airflow in the shaping air duct and distribute a small portion of the airflow to the shaping air duct.

[0028] See Figures 1 to 7 In the above embodiments provided by the present invention, the air duct 9 is further provided with an airflow deflection structure 63. The airflow deflection structure 63 is a multi-stage arc-shaped step structure, which deflects the high-speed, high-temperature airflow by 90 degrees and blows it out.

[0029] See Figures 1 to 7 In the above embodiments provided by the present invention, a high-speed fan 64 is further provided in the first long arm 1 and the second long arm 2, and the air outlet of the high-speed fan 64 is connected to the air inlet 62. The high-speed fan 64 can generate high-speed airflow, which is a mature prior art.

[0030] See Figures 1 to 7 In the above embodiments provided by the present invention, a flow-dividing and mixing space 82 is further provided between the airflow distributor 8 and the shaped air outlet 5. The flow-dividing and mixing space 82 enables the high-temperature airflow and the low-temperature airflow to mix fully, resulting in a stable shaped airflow output.

[0031] See Figures 1 to 7 In the above embodiments provided by the present invention, a further embodiment includes an air inlet gap 71 formed at one end of the shaping air duct 7, which communicates with the air inlet 62. The air inlet gap 71 allows a small portion of the room temperature high-speed airflow to enter the shaping air duct 7, thereby enabling the shaping airflow to reach the required shaping temperature.

[0032] See Figures 1 to 7 In the above embodiments provided by the present invention, the air volume of the shaped air outlet 4 is Q. 造 The shaped air volume of the shaped air outlet 5 is Q. 定 Let Q be the total air volume inside the cavities of the long arms 1 and 2. Then: Where a and b are proportionality constants, and a + b = 1, the value of a ranges from 0.6 to 0.7, and the value of b ranges from 0.3 to 0.4. According to the law of conservation of flow, the airflow at the shaping outlet is significantly lower than that at the styling outlet, thus ensuring sufficient airflow for the styling by adjusting the airflow distribution ratio (approximately 60-70% for styling and 30-40% for shaping). In this embodiment, the value of a is 0.65, and the value of b is 0.35, resulting in an airflow distribution ratio of 65% for styling and 35% for shaping.

[0033] See Figures 1 to 7 In the above embodiments provided by the present invention, the styling temperature of the shaped air outlet is T. 造 The shaping temperature of the shaping air outlet is T. 定 Then: T=T 造 -T 定 Where T represents the styling temperature difference, and the value of T ranges from 50 degrees to 80 degrees Celsius. In this embodiment, it is 60 degrees Celsius. In this embodiment, the styling temperature of the styling vent is 140-180 degrees Celsius, which can effectively straighten the hair. The above temperature difference can better achieve the styling effect and provide a better setting result.

[0034] In summary, the above descriptions are merely embodiments of the present invention and are used only to illustrate the principles of the invention, not to limit the scope of protection of the invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
