Description

Technical Field

[0001] This application relates to the technical field of hair styling products, and in particular to a hair styling accessory and hair styling appliance. Background Technology

[0002] Hair styling equipment refers to professional tools and instruments used for hair care, styling, etc. Based on their specific functions, they can be categorized into hair cutting equipment, hair straightening equipment, hair curling equipment, and hair conditioning equipment. Among these, hair straightening equipment is one of the most commonly used.

[0003] In traditional techniques, hair straightening devices mainly use heated plates to clamp the hair and pull it to straighten it. However, this method not only subjectes the hair to extra pulling force, making it prone to damage, but also prevents the heat from the plates from being evenly distributed to the hair, resulting in poor drying and straightening effects. Utility Model Content

[0004] Therefore, it is necessary to provide a hair styling accessory and tool to address the problems of hair damage and poor drying and straightening effects caused by traditional techniques.

[0005] A first aspect of this application provides a hair accessory comprising:

[0006] A housing, wherein an air supply duct is formed inside the housing for airflow, the housing includes a first clamping plate and a second clamping plate, a cavity is formed between the first clamping plate and the second clamping plate, the cavity extending radially in a first direction; and

[0007] An air guide is provided at least in one of the first clamping plate and the second clamping plate and close to the cavity. The air guide includes a first structural member and a second structural member. A portion of the first structural member and a portion of the second structural member overlap along the orthographic projection of the second direction of the hair accessory, and the overlapping portions are spaced apart to form an air outlet. The air outlet connects the air supply duct to the cavity. The first direction intersects the second direction.

[0008] This hair styling accessory is installed in a hair styling appliance and is suitable for use in scenarios involving drying and straightening hair. Specifically, since the first and second clamping plates of the housing cooperate to form a cavity extending radially along the first direction of the hair styling accessory, hair can be placed in the cavity to allow the hair styling accessory to fit the hair. Furthermore, an air guide is installed on at least one of the first and second clamping plates and positioned close to the cavity. Since a portion of the first structural member and a portion of the second structural member of the air guide overlap in their orthographic projections along the second direction of the hair styling accessory, this overlapping portion can cooperate to form an air outlet. Therefore, the air duct formed inside the housing can be connected to the cavity through the air outlet. When... When using hair styling tools, airflow is delivered into the air duct, and then flows from the air duct through the air outlet into the hair cavity to blow-dry the hair inside the cavity and achieve a styling effect. On the one hand, the high-speed airflow can quickly remove moisture from the hair, thus achieving fast and effective drying; on the other hand, the high-speed airflow also straightens the hair, thus achieving a straight hair style. Compared with traditional techniques, airflow replaces the flat iron, avoiding additional pulling force on the hair and preventing damage. The high-speed airflow helps to disperse clumps of hair, allowing the airflow to contact the hair more evenly and effectively, resulting in better drying and straightening effects.

[0024] In one embodiment, the housing further includes an outer shell, which is mounted outside the inner shell, and a heat-insulating cavity is formed between the outer shell and the inner shell;

[0025] The outer shell is recessed on the side of the cavity to form mounting holes, and the air guide is embedded in the mounting holes.

[0026] In one embodiment, two of each of the air guide, the inner shell and the outer shell are provided and are matched one-to-one, and the air inlet is connected to the two air collection chambers and cooperates to form the air supply duct.

[0027] The air inlet is equipped with a flow divider, which is used to guide the airflow from the air inlet into the two air collection chambers.

[0028] In one embodiment, the air inlet area is greater than the sum of the cross-sectional areas of the two air collection chambers.

[0030] In one embodiment, the first clamping plate and / or the second clamping plate are provided with a constraint member, which is located on the side of the cavity opposite to the airflow direction.

[0031] In one embodiment, both the first clamping plate and the second clamping plate are provided with constraint members on the sidewalls of the cavity, and the constraint members provided on the first clamping plate and the constraint members provided on the second clamping plate are staggered in the first direction.

[0032] A second aspect of this application also proposes a hair accessory comprising:

[0033] A housing, wherein an air supply duct is formed inside the housing for airflow, the housing includes a first clamping plate and a second clamping plate, a cavity is formed between the first clamping plate and the second clamping plate, the cavity extending radially in a first direction; and

[0034] An air guide is provided at least in one of the first clamping plate and the second clamping plate and close to the cavity. The air guide is provided with a first structural member, a second structural member and a third structural member. The first structural member and the third structural member are respectively connected to the housing. The second structural member is disposed between the first structural member and the third structural member.

[0038] This hair styling accessory is installed in a hair styling appliance and is suitable for use in scenarios involving drying and straightening hair. Specifically, since the first and second clamping plates of the housing cooperate to form a cavity extending radially along the first direction of the hair styling accessory, hair can be placed in the cavity to allow the hair styling accessory to fit the hair. Furthermore, an air guide is installed on at least one of the first and second clamping plates, positioned close to the cavity. Because a portion of the first structural member and a portion of the second structural member of the air guide overlap along the second direction of the hair styling accessory, this overlapping portion can cooperate to form a first air outlet. Simultaneously, the overlapping portion of the second and third structural members along the second direction forms a second air outlet. Therefore, the first and second air outlets can ventilate the hair styling accessory. The airflow channel formed inside the device is connected to the cavity. When the hair styling tool is used, airflow is delivered into the airflow channel. The airflow then flows from the airflow channel through the first and second air outlets into the cavity, blowing the hair inside the cavity to achieve a styling effect. On the one hand, the high-speed airflow can quickly remove moisture from the hair, thus achieving fast and effective drying. On the other hand, the high-speed airflow also straightens the hair, thus achieving a straight hair style. Compared with traditional techniques, the airflow replaces the flat iron, avoiding additional pulling force on the hair and preventing damage. The high-speed airflow helps to disperse clumps of hair, allowing the airflow to contact the hair more evenly and effectively, resulting in better drying and straightening effects.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0064] See Figures 1 to 3 This application describes a hair styling accessory 100, which is used in a hair styling appliance as a blower component to blow-dry the user's hair. For example, the hair styling appliance may be, but is not limited to, a hair dryer.

[0065] For example, in one embodiment, the hair styling appliance includes a main unit and a hair styling accessory 100, the hair styling accessory 100 being disposed on the main unit for installation and fixation via the main unit. The main unit has a grip for convenient handheld use by the user.

[0066] Please continue reading. Figure 3 and Figure 4 In this application, the hair styling accessory 100 includes a housing 10, and an air supply duct 11 is formed inside the housing 10 for airflow.

[0067] The main unit has an internal mounting cavity, and an airflow generating device is installed inside the mounting cavity; the air supply duct 11 is connected to the mounting cavity, and the airflow generating device is used to deliver airflow into the air supply duct 11.

[0068] In addition, the main unit's casing has an air inlet, which is used to connect the mounting cavity with the external environment.

[0069] In use, the airflow generator is activated, and air from the external environment is drawn into the mounting cavity through the air inlet, thus forming a high-speed airflow driven by the airflow generator. Furthermore, driven by the airflow generator, the airflow flows into the air supply duct 11 to deliver air to the hair styling accessory 100.

[0070] For example, the airflow generating device is a fan, which can be any type of fan, such as a bladed fan or a bladeless fan. The specific type can be selected flexibly according to actual needs, and no specific limitation is made here.

[0071] In addition, a heating device can be installed inside the mounting cavity of the main unit, and along the airflow direction within the mounting cavity, the heating device is positioned downstream of the air outlet of the airflow generator. Thus, when the airflow passes through the heating device, it is heated into a high-temperature airflow, which, when applied to the hair, achieves better drying and straightening results.

[0072] For example, the heating device can be any of the following: heating wire, heating tube, heating element, etc. The choice can be made flexibly according to actual needs, and no specific limitation is made here.

[0073] Please continue reading. Figure 1 and Figure 2 In this application, the housing 10 includes a first clamping plate 16 and a second clamping plate 17, and a cavity 12 is formed between the first clamping plate 16 and the second clamping plate 17. The cavity 12 extends radially in a first direction. Specifically, the housing 10 has an approximate cylindrical structure. The cavity 12 is designed to facilitate the insertion of hair and allows the hair to move within the cavity 12, thereby enabling better drying and straightening of different parts of the hair.

[0074] Please continue reading. Figure 1 , Figure 2 , Figure 5 , Figures 7 to 9 In addition, the hair styling accessory 100 also includes an air guide 20, which is disposed at least in one of the first clamping plate 16 and the second clamping plate 17 and close to the cavity 12. The air guide 20 includes a first structural member 21 and a second structural member 22. A portion of the first structural member 21 and a portion of the second structural member 22 overlap along the orthographic projection of the second direction of the hair styling accessory 100, and the overlapping portions are spaced apart to form an air outlet 30. The air outlet 30 connects the air supply duct 11 and the cavity 12. The first direction intersects the second direction.

[0075] In this embodiment, the first direction is Figure 1 Arrow S1 points in the direction. The second direction is... Figure 5 Arrow S2 in the diagram points to; it is understood that in other embodiments, the first direction and the second direction only need to satisfy the limiting relationship, and other direction settings can also be presented.

[0076] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: The hair styling accessory 100 of this solution is installed in a hair styling appliance and is suitable for use scenarios involving drying and straightening hair. Specifically, since the first clamping plate 16 and the second clamping plate 17 of the housing 10 cooperate to form a cavity 12 extending radially along the first direction of the hair styling accessory 100, hair can be placed in the cavity 12 so that the hair styling accessory 100 fits with the hair. On this basis, an air guide 20 is installed on at least one of the first clamping plate 16 and the second clamping plate 17 and arranged close to the cavity 12. Since the portion of the first structural member 21 of the air guide 20 and the portion of the second structural member 22 overlap along the orthographic projection of the second direction of the hair styling accessory 100, the overlapping portion can cooperate to form an air outlet 30, thus allowing air to pass through. The outlet 30 connects the air duct 11 formed inside the housing 10 with the cavity 12. When the hair styling tool is used, airflow is delivered into the air duct 11, and the airflow can further flow from the air duct 11 into the cavity 12 through the outlet 30 to blow-dry the hair in the cavity 12 to achieve a styling effect. On the one hand, the high-speed airflow can quickly remove moisture from the hair, thereby achieving fast and effective drying. On the other hand, the high-speed airflow also straightens the hair, thus achieving straight hair styling. Compared with traditional technology, the airflow replaces the flat iron, avoiding additional pulling force on the hair and preventing damage. The high-speed airflow helps to disperse clumps of hair, allowing the airflow to contact the hair more evenly and effectively, resulting in better drying and straightening effects.

[0077] Based on the above embodiment, the first structural member 21 and the second structural member 22 overlap in position and form opposite walls that are parallel to each other for the air outlet 30. This parallel arrangement of the two opposite walls forming the air outlet 30 avoids pressure loss caused by internal circulation of airflow through the air outlet 30 when the two walls are designed with flared openings. Simultaneously, the parallel walls effectively define the airflow direction entering the cavity 12, allowing the airflow to blow towards the hair to be styled in the desired direction, or to flow towards the subsequent guide structure in the desired direction, facilitating airflow control and improving airflow utilization efficiency.

[0078] Alternatively, as an alternative to the above embodiment, in another embodiment, the first structural member 21 and the second structural member 22 overlap and form the opposing walls of the air outlet 30, which have a contracting trend along the air outlet direction. Since the two overlapping and opposing walls surrounding the air outlet 30 exhibit a contracting structure with decreasing width, this facilitates the guidance of airflow through the air outlet 30, increases the pressure at the air outlet 30, further enhances the flow rate, and strengthens the drying and straightening effect of the airflow on the hair.

[0079] Based on any of the above embodiments, the distance between the parallel walls of the first structural member 21 and the second structural member 22 that overlap and form the air outlet 30 is 0.8mm to 2.5mm. For example, the distance between the two parallel walls forming the air outlet 30 can be 0.8mm, 1.2mm, 1.5mm, 1.8mm, 2.0mm, 2.5mm, etc. The flexible design of the distance value allows the airflow from the air outlet 30 into the cavity 12 to vary as needed to suit the usage requirements of different hair styling tools. Furthermore, when the minimum distance value is selected as 0.8mm, it avoids the situation where the spacing is too small, resulting in low airflow and high noise, affecting performance and user experience; while when the maximum distance value is selected as 2.5mm, it avoids the situation where the spacing is too large, which is not conducive to airflow guidance and also hinders the formation of the Coanda effect.

[0080] It should be noted that the Coanda effect refers to the physical phenomenon where a fluid (water or air) deviates from its original flow direction and flows along the surface of a convex object. Specifically, the Coanda effect mentioned in this application refers to the ability of the airflow blowing from the outlet 30 to adhere to the wall surface of the second structural member 22.

[0081] Furthermore, the thickness of the first structural member 21 is 0.6mm to 1.0mm. For example, the thickness of the first structural member 21 can be 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, etc.

[0082] The thickness of the second structural component 22 is 1.3mm to 1.7mm. For example, the thickness of the second structural component 22 can be 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, etc.

[0083] By reasonably setting the thickness of the first structural component 21, it is possible to ensure that the air guide component 20 has sufficient structural strength, while avoiding excessive thickness of the first structural component 21 and the second structural component 22, which would occupy too much installation space and be detrimental to the miniaturization design of the hair styling accessory 100.

[0084] In another embodiment, the plane containing the overlapping first structural member 21 and the second structural member 22 forming the air outlet 30 and the plane containing the first direction has an angle of 0° to 15°. Thus, the two opposing walls forming the air outlet 30, due to their small inclination angle, can vectorically divide the airflow blowing obliquely towards the hair into airflow perpendicular to the hair direction and airflow stretching the hair direction. This range of inclination angles allows for a larger component of the airflow stretching the hair, thereby smoothing and guiding the hair cuticles to adhere tightly to the hair shaft, resulting in smooth, closed hair, reducing friction between hairs, and effectively preventing frizz and static electricity. This significantly reduces physical damage to the hair cuticles, providing a gentler styling method and making the hair smoother. Furthermore, the inclination angle of the two opposing walls also creates a better guiding effect on the airflow passing through the air outlet 30, making the airflow through the air outlet 30 smoother and more effective. In addition, designing the wall surface with a slope makes it easier to reserve a draft angle during manufacturing and processing, thus facilitating demolding from the mold.

[0085] For example, in this application, the angle between the plane containing the opposite walls of the first structural member 21 and the second structural member 22 overlapping to form the air outlet 30 and the plane containing the first direction is 5°. Designing the inclination angle of the two opposite walls forming the air outlet 30 to be 5° ensures that the airflow component acting in the direction of hair stretching meets the usage requirements, and prevents the friction between the airflow and the hair from being too large or too small, thus avoiding frizz and static electricity. This provides a gentler styling method, making the hair smoother and improving the straightening effect.

[0086] Please continue reading. Figure 5 and Figure 7 In one embodiment, the wall portion where the first structural member 21 and the second structural member 22 overlap in the second direction can be designated as the first wall 211; correspondingly, the wall portion where the second structural member 22 and the first structural member 21 overlap in the second direction can be designated as the second wall 221.

[0087] Please continue reading. Figure 5 and Figure 7 Furthermore, based on the above embodiments, the second structural member 22 has a first guide surface 222, which is connected to the second wall surface 221, and a portion of the first guide surface 222 is parallel to a portion of the wall surface of the first structural member 21; the first guide surface 222 can guide the airflow blown out from the air outlet 30. Specifically, the first guide surface 222 is a smooth and straight wall surface, which has low flow resistance to the airflow and a guiding effect on the airflow, helping to guide the airflow to flow out of the air outlet 30 more smoothly and effectively.

[0088] Furthermore, based on the above embodiments, the second structural component 22 further includes a second guide surface 223, which connects to the first guide surface 222 and can change the direction of the airflow guided by the first guide surface 222. The provided second guide surface 223 can further guide the airflow flowing through the first guide surface 222, so as to guide the airflow to converge and flow into the cavity, ensuring the drying and straightening effect of the airflow on the hair.

[0089] It is necessary to explain that the first guide surface 222 and the second guide surface 223 constitute the above-mentioned guide structure.

[0090] Please continue reading. Figure 1 , Figure 3 and Figure 5 In this application, the cavity 12 has an exhaust port 121. After the airflow enters the cavity 12 to dry and / or straighten the hair, it can be discharged from the cavity 12 through the exhaust port 121. This ensures that the airflow continuously flows into and out of the cavity 12, guaranteeing continuous airflow action on the hair and preventing wind noise caused by airflow collision within the cavity 12 due to untimely airflow discharge. Furthermore, the side of the second guide surface 223 away from the first guide surface 222 is connected to the wall forming the exhaust port 121. This allows for better guidance of the airflow into the cavity 12, preventing airflow from being lost due to the constraint of the second guide surface 223.

[0091] It should be noted that, in one embodiment of this application, both the first guide surface 222 and the second guide surface 223 are inclined, and the angle between the plane containing the second guide surface 223 and the plane containing the first direction is greater than the angle between the plane containing the first guide surface 222 and the plane containing the first direction. Alternatively, the plane containing the first guide surface 222 is parallel to the plane containing the first direction, and the second guide surface 223 is inclined relative to the first guide surface 222.

[0092] In simple terms, both the first guide surface 222 and the second guide surface 223 are inclined toward the cavity 12, or the first guide surface 222 is not inclined, but the second guide surface 223 is inclined. On the one hand, the first guide surface 222 and the second guide surface 223 are formed into a sloping structure, which can guide the airflow from the outlet 30 in a gradual and relay effect, making the airflow more effectively flow toward the cavity 12. On the other hand, from a fluid perspective, the flow velocity of the boundary layer near the wall is zero, and the higher the gas velocity, the higher the pressure. A low-pressure area is formed at the transition between the first guide surface 222 and the second guide surface 223, while a high-pressure area is formed in the main jet area flowing out of the outlet 30. A pressure gradient is formed between the low-pressure area and the high-pressure area, which can then adsorb the airflow and prevent the airflow from being ejected at the outlet 30 and escaping the restraint of the first guide surface 222 and / or the second guide surface 223, thus preventing airflow loss.

[0093] Please continue reading. Figure 4 , Figure 5 , Figure 7 and Figure 9 In another embodiment, the hair styling accessory 100 further includes at least two rectifiers 40, which connect the first structural member 21 and the second structural member 22. All the rectifiers 40 are arranged at intervals along a third direction of the hair styling accessory 100, wherein the third direction intersects with both the first and second directions.

[0094] For example, a third party is Figure 9 The direction of the middle arrow S3.

[0095] Specifically, since the housing 10 in this application has an approximate cylindrical structure, the third direction specifically refers to the length direction or axial direction of the hair styling accessory 100. Because the first structural member 21 and the second structural member 22 also extend along the third direction, the air outlet 30 formed by the cooperation of the first structural member 21 and the second structural member 22 has an elongated opening structure extending along the third direction. Based on this, at least two rectifiers 40 are installed and arranged at intervals along the third direction between the first structural member 21 and the second structural member 22. This allows the rectifiers 40 to divide the airflow as it flows from the air outlet 30, making the blown airflow more uniform and reducing turbulence.

[0096] For example, the rectifier 40 is specifically a plate, which can be integrally formed with the first structural component 21 and the second structural component 22, or it can be detachably assembled. When it is a detachably assembled mounting structure, the connection method between the plate and the first structural component 21 and the second structural component 22 can be at least one of screw connection, snap connection, adhesive connection, magnetic connection, etc., and can be flexibly selected according to actual needs.

[0097] It should be noted that the side wall of the rectifier 40 near the cavity 12 should be flush with the side wall of the guide member near the cavity 12, or the height of the side wall of the rectifier 40 near the cavity 12 should be lower than the height of the side wall of the guide member near the cavity 12, so as to avoid the rectifier 40 extending into the cavity 12 and interfering with the hair, thus affecting the styling effect of the airflow on the hair.

[0098] Please continue reading. Figures 3 to 7 ,as well as Figure 10In one embodiment of this application, the housing 10 includes a housing base 15 and an inner housing 13. The inner housing 13 is connected to the housing base 15. An air guide 20 is disposed on the housing base 15 and installed on the inner housing 13. The air guide 20 and the inner housing 13 cooperate to form an air collection cavity 50. The wall surface of the inner housing 13 used to form the air collection cavity 50 is curved. The air collection cavity 50 is connected to the air outlet 30. An air inlet 151 is formed inside the housing base 15. The air inlet 151 is connected to the air collection cavity 50 to form an air supply duct 11.

[0099] The air guide 20 and the inner shell 13 cooperate to form an air collecting cavity 50, which can be used to accommodate airflow. The wall surface of the inner shell 13 used to form the air collecting cavity 50 is designed as a curved surface, specifically a concave and smooth curved surface, which helps to reduce the pressure loss of the airflow flowing into the air collecting cavity 50. The air inlet 151 formed inside the housing 15 is used to communicate with the mounting cavity of the main unit, so that the airflow in the mounting cavity can flow into the air collecting cavity 50 through the air inlet 151, and then be delivered to the air outlet 30.

[0100] Please continue reading. Figure 10 Furthermore, the housing 10 also includes an outer shell 14, which is installed outside the inner shell 13, and a heat insulation cavity 60 is formed between the outer shell 14 and the inner shell 13. In use, controlling the power supply to the heating device causes it to heat up, thereby heating the airflow within the mounting cavity to generate a high-temperature airflow. This high-temperature airflow flows into the gas collecting cavity 50 and comes into contact with the housing 10, causing heat transfer and raising the temperature of the housing 10. If a user touches the housing 10 at this time, they will be burned. To address this, this embodiment designs the housing 10 as an inner shell 13 and an outer shell 14 installed side-by-side, with a heat insulation cavity 60 formed between them. Even if the inner shell 13 comes into contact with the high-temperature airflow and conducts heat, the heat insulation cavity 60 can prevent further heat transfer from the inner shell 13 to the outer shell 14, thus preventing the outer shell 14 from becoming too hot.

[0101] Furthermore, since there is an air layer in the heat insulation cavity 60 between the inner shell 13 and the outer shell 14, the heat insulation and anti-scalding effect can be better achieved.

[0102] Please continue reading. Figure 9 To better assemble and fix the air guide 20 to the housing 10, in one embodiment, the outer shell 14 has recessed mounting holes 141 on the side of the cavity 12, and the air guide 20 is embedded in the mounting holes 141. The shape and size of the air guide 20 and the mounting holes 141 are designed to fit together, so the air guide 20 can be completely fitted and housed in the mounting holes 141. This not only makes the air guide 20 firmly and reliably installed, but also makes the air guide 20 and the housing 10 have a compact structure and good overall appearance.

[0103] Optionally, the air guide 20 can be fastened in the mounting hole 141 by fitting, or the air guide 20 can be fixed to the housing 10 by at least one of the following methods: threaded connection, snap-fit ​​connection, adhesive bonding, riveting, etc. The appropriate method can be selected flexibly according to actual needs.

[0104] Please continue reading. Figure 5 Furthermore, based on any of the above embodiments, two air guides 20, two inner shells 13, and two outer shells 14 are provided and matched one-to-one. The air inlet 151 is connected to both air collection chambers 50 and cooperates to form an air delivery duct 11. With this configuration, when the hair styling tool is used, the air outlets 30 on both sides can simultaneously blow airflow into the hair in the cavity 12, increasing the air volume to improve the drying and straightening effect on the hair.

[0105] Please continue reading. Figure 10 Furthermore, the air inlet 151 is equipped with a flow divider 152, which guides the airflow from the air inlet 151 into the two air collection chambers 50. This ensures that the airflow into the two air collection chambers 50 is evenly distributed, guaranteeing that the airflow from the two air outlets 30 is uniform and consistent, facilitating the delivery of even airflow to the hair on both sides, thereby straightening the hair.

[0106] It should be noted that, along the airflow direction, the air inlet 151 should adopt a structure design with a gradually expanding cross-sectional area to reduce the airflow velocity, reduce noise, stabilize the airflow velocity, and facilitate airflow guidance.

[0107] It should be noted that the cross-sectional area of ​​the air inlet 151 adopts a gradually expanding structural design, that is, it is necessary to ensure that the air intake area of ​​the air inlet 151 is greater than the sum of the cross-sectional areas of the two air collecting chambers 50. Among them, the cross-sectional area of ​​the air collecting chamber 50 is the area enclosed by the wall of the air collecting chamber 50 formed after cutting the hair styling accessory 100 along the second direction.

[0108] Please continue reading. Figure 4 and Figure 5 Furthermore, in one embodiment, the distance between the end of the rectifier 40 near the air outlet 30 and the inner shell 13 in the first direction is set to D, where D > 1 mm. This setting provides a buffer distance and time for the airflow to flow out of the air outlet 30, allowing the airflow entering the upper side of the air collection chamber 50 to be fully turned and rectified, thereby improving the guiding effect of the airflow flowing out of the air outlet 30.

[0109] Optionally, the distance D is 3mm to 5mm. Of course, in other optional embodiments, the distance D can also take other numerical ranges, which are all within the protection scope of this application, and will not be elaborated here.

[0110] Furthermore, based on any of the above embodiments, a constraint member (not shown in the figure) is provided on the first clamping plate 16 and / or the second clamping plate 17. The constraint member is located on the side of the cavity 12 opposite to the airflow direction. In use, the airflow rate and velocity blown into the cavity 12 from the air outlet 30 are relatively large, and the airflow easily overflows from the openings 122 at the upper ends of the first clamping plate 16 and the second clamping plate 17. By providing the constraint member, the constraint member can restrain the hair within a certain range, and at the same time prevent the hair from being blown out from the upper openings 122 by the turbulent airflow, thereby avoiding the hair from spreading out and enhancing the straightening effect.

[0111] For example, the constraint can be a long strip-shaped protrusion extending in a third direction, a comb-like structure, etc.

[0112] Furthermore, both the first clamping plate 16 and the second clamping plate 17 are provided with constraint members on the side walls that form the cavity 12, and the constraint members provided on the first clamping plate 16 and the constraint members provided on the second clamping plate 17 are staggered in the first direction. With this arrangement, on the one hand, the amount of hair that can enter the cavity 12 can be guaranteed, that is, the two staggered constraint members can guarantee the amount of hair that can be contained in the cavity. If the two constraint members are set opposite each other, very little hair will be able to enter the cavity 12, and it will also be inconvenient for the user to align and operate. On the other hand, it can increase the hair straightening time. That is, the two staggered constraint members can make a strand of hair pass through the two constraint members one after the other, so that the hair is subjected to airflow in the cavity 12 and the straightening time is longer, ensuring sufficient straightening time to enhance the straight hair styling effect.

[0113] Please continue reading. Figure 1 and Figure 11 In another alternative embodiment, this application also proposes a different structural form of hair styling accessory 100, which includes a housing 10 and an air guide 20.

[0114] The housing 10 has an internal air supply duct 11 for airflow. The housing 10 includes a first clamping plate 16 and a second clamping plate 17, with a cavity 12 formed between the first clamping plate 16 and the second clamping plate 17. The cavity 12 extends radially in a first direction. An air guide 20 is disposed at least in one of the first clamping plate 16 and the second clamping plate 17 and close to the cavity 12. The air guide 20 is provided with a first structural member 21, a second structural member 22 and a third structural member 23. The first structural member 21 and the third structural member 23 are respectively connected to the housing 10. The second structural member 22 is disposed between the first structural member 21 and the third structural member 23. A portion of the first structural member 21 and a portion of the second structural member 22 overlap along the orthographic projection of the second direction of the hairdressing accessory 100, and the overlapping portions are spaced apart to form a first air outlet 30a.

[0115] A portion of the second structural member 22 and a portion of the third structural member 23 overlap along the orthographic projection of the second direction of the hair styling accessory 100, and the overlapping portions are spaced apart to form a second air outlet 30b, and the two opposite sidewalls forming the first air outlet 30a and / or the two opposite sidewalls forming the second air outlet 30b are parallel to each other; the first air outlet 30a and the second air outlet 30b connect the air supply duct 11 and the cavity 12; wherein, the first direction intersects the second direction.

[0116] The hair styling accessory 100 of this solution is installed in a hair styling appliance and is suitable for use in scenarios involving drying and straightening hair. Specifically, since the first clamping plate 16 and the second clamping plate 17 of the housing 10 cooperate to form a cavity 12 extending radially along the first direction of the hair styling accessory 100, hair can be placed in the cavity 12 so that the hair styling accessory 100 fits the hair. On this basis, an air guide 20 is installed on at least one of the first clamping plate 16 and the second clamping plate 17 and is arranged close to the cavity 12. Since a portion of the first structural member 21 and a portion of the second structural member 22 of the air guide 20 overlap along the orthographic projection of the hair styling accessory 100 in the second direction, the overlapping portion can cooperate to form a first air outlet 30a. At the same time, the overlapping portion of the second structural member 22 and the third structural member 23 along the second direction forms a second air outlet 30b. Therefore, the first air outlet... The first air outlet 30a and the second air outlet 30b connect the air duct 11 formed inside the housing 10 with the cavity 12. When the hair styling tool is used, airflow is delivered into the air duct 11, and the airflow can further flow from the air duct 11 into the cavity 12 through the first air outlet 30a and the second air outlet 30b to blow-dry the hair in the cavity 12 to achieve a styling effect. On the one hand, the high-speed airflow can quickly remove moisture from the hair, thereby achieving fast and effective drying. On the other hand, the high-speed airflow also straightens the hair, thereby achieving straight hair styling. Compared with traditional technology, the airflow replaces the flat iron, avoiding additional pulling force on the hair and preventing damage. The high-speed airflow helps to disperse clumps of hair, allowing the airflow to contact the hair more evenly and effectively, resulting in better drying and straightening effects.

[0117] Furthermore, the air outlet 30 has specific requirements regarding its airflow area. If the airflow area of ​​the air outlet 30 is too small, motor surge may easily occur; conversely, if the airflow area of ​​the air outlet 30 is too large, the airflow will be too dispersed, resulting in poor drying performance. Experimental verification shows that a single-row air outlet 30 has poorer airflow guidance than a double-row air outlet 30 (i.e., the first air outlet 30a and the second air outlet 30b). Simultaneously, the airflow from the lower air outlet (i.e., the second air outlet 30b) can guide the airflow from the upper air outlet (i.e., the first air outlet 30a). Therefore, the double-row air outlet 30 (i.e., the first air outlet 30a and the second air outlet 30b) offers higher precision in controlling the airflow direction. At the same time, jet propagation involves energy dissipation, which generates noise. The design of the double-row air outlet 30 allows for a clearer airflow direction, reduces energy dissipation, and decreases turbulence, ultimately leading to better noise control.

[0118] Furthermore, multiple second structural members 22 can be provided, and the multiple second structural members 22 are arranged at intervals along the first direction, forming a third air outlet (not shown in the figure) between two adjacent second structural members 22. In this way, at least three rows of air outlets 30 (i.e., the first air outlet 30a, the second air outlet 30b, and the third air outlet) arranged along the first direction can be formed on the air guide member 20, thereby increasing the air outlet area of ​​the hair styling accessory 100, and more accurately controlling the airflow direction blown into the cavity 12, while reducing noise and improving the quietness of the hair styling appliance.

[0119] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0120] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
