Description

Technical Field

[0001] This disclosure relates to the field of hair care devices, and in particular to a hair curling attachment and hair curling device. Background Technology

[0002] As people's pursuit of hair styling efficiency and hair care effects continues to increase, hair curling devices are being used more and more widely in the market. However, existing hair curling devices generally achieve hair curling and styling by manually clamping the hair and rotating the curling device, which is complicated to operate and produces unsatisfactory curling results. Utility Model Content

[0003] In view of this, the purpose of this disclosure is to provide a hair curling attachment and a hair curling device to improve the technical problems of complex operation and poor hair curling effect in the prior art.

[0004] To achieve at least one of the above objectives, this disclosure provides the following technical solutions:

[0005] Firstly, a hair curling accessory is provided, including:

[0006] The ring component has an annular channel extending circumferentially therein and multiple outlets connected to the annular channel, the multiple outlets being spaced apart circumferentially along the flow cross section of the annular channel.

[0007] A connector, disposed on the annular member, has an air inlet configured to guide fluid into the annular channel and out from multiple outlets;

[0008] In this embodiment, fluid flowing out through multiple outlets is blown toward the outer surface of the annular component, forming an airflow that flows around the outer surface of the annular component. At least a portion of the airflow flows around the inner and outer sides of the outer surface of the annular component. The annular component includes a first tube component and a second tube component located on opposite sides of the axis of the connector, with the airflow directions of the first tube component and the second tube component being opposite. In some embodiments, the multiple outlets extend circumferentially along the annular component, causing at least a portion of the airflow to flow around the outer surface of the annular component along the circumferential direction of the flow cross-section of the annular channel.

[0009] In some embodiments, multiple outlets are arranged spirally extending along the outer surface of the annular member, such that at least a portion of the airflow spirals around the outer surface of the annular member in the circumferential direction.

[0010] In some embodiments, the plane containing the flow cross-section of the annular channel is a first plane, and there are multiple first planes;

[0011] The ring-shaped component is cut by multiple first planes to form multiple first cross sections;

[0012] Within the same first plane, the sum of the area of ​​the first cross section and the area of ​​the flow cross section of the annular channel is the first total area;

[0013] Among them, at least two of the first total areas are different.

[0014] In some embodiments, the connector is connected to the outside of the ring member along the top-bottom direction of the ring member;

[0015] The first total area increases along the left and right directions of the ring-shaped component;

[0016] Among them, the top and bottom directions of the ring component, the left and right directions of the ring component, and the axial direction of the ring component are perpendicular to each other.

[0017] In some embodiments, the ring-shaped component includes:

[0018] The ring skeleton has an annular channel inside, and multiple hole components are opened circumferentially along the flow section of the annular channel.

[0019] Multiple blades are connected to the outside of the annular skeleton at intervals along the circumferential flow section of the annular channel;

[0020] The slit between two adjacent blades forms an outlet, which is connected to an annular channel through a perforated assembly.

[0021] In some embodiments, the ring skeleton is divided into two detachable semi-ring structures along its axial direction.

[0022] In some embodiments, a plurality of reinforcing members are provided at intervals along the circumference of the annular member on the blade, and the plurality of reinforcing members extend from one end of the blade near the annular frame into the outlet.

[0023] In some embodiments, the aperture assembly includes a plurality of grid apertures arranged circumferentially along the ring skeleton.

[0024] In the above technical solution, multiple outlets are set to guide the fluid to blow onto the outer surface of the ring component, forming an airflow that flows around the outer surface of the ring component. At least part of the airflow flows around the inner and outer sides of the outer surface of the ring component. Based on the Coanda effect, the hair can be attracted by the airflow and automatically adhere to and wrap around the outer surface of the ring component, making the hair curled. Subsequent airflow can continue to blow onto the hair to heat and set the curled hair. This curling method can automatically curl hair, is simple to operate, and helps to improve the curling effect.

[0025] Furthermore, the hair curling attachment is designed as a ring-shaped component, so that the two airflows formed on opposite sides of the ring-shaped component have opposite directions of rotation. Different directions of curling can be achieved by using airflows with different rotation directions, and it is easy to operate.

[0026] In addition, the use of a ring-shaped component structure helps to enhance the structural strength of the curling attachment, so as to support more hair to be wrapped around the outer surface of the ring-shaped component, thereby improving the curling efficiency.

[0027] Secondly, a hair curling accessory is also provided, including a connector and a first tube member and a second tube member connected to the connector and spaced apart from each other.

[0028] The connector has an air inlet configured to guide fluid into the inner cavity of the first tube member and the inner cavity of the second tube member;

[0029] The first tube component has a plurality of first air outlets communicating with its inner cavity. The plurality of first air outlets are arranged at intervals along the circumference of the first tube component and guide fluid to be blown out along the outer surface of the first tube component to form a first airflow flowing around the outer surface of the first tube component.

[0030] The second tube component has multiple second air outlets communicating with its inner cavity. The multiple second air outlets are spaced apart along the circumference of the second tube component and guide fluid to be blown out along the outer surface of the second tube component to form a second airflow flowing around the outer surface of the second tube component.

[0031] The first tube component and the second tube component are respectively disposed on both sides of the axis of the connector, and at least a portion of the first airflow and at least a portion of the second airflow have opposite flow directions.

[0032] In some embodiments, the first airflow flows circumferentially around the outer surface of the first tube member; or, the first airflow spirally flows circumferentially around the outer surface of the first tube member along its extension direction.

[0033] In some embodiments, the second airflow flows around the outer surface of the second tube member in the circumferential direction; or, the second airflow flows spirally around the outer surface of the second tube member in the extending direction.

[0034] In some embodiments, the maximum outer diameter of the first tube component is different from the maximum outer diameter of the second tube component.

[0035] In the above technical solution, by setting two tube components (a first tube component and a second tube component) and opening multiple air outlets (multiple first air outlets and multiple second air outlets) on the two tube components, the fluid can be guided to blow towards the outer surface of the two tube components, forming a first airflow and a second airflow flowing around the outer surface of the two tube components. Based on the Coanda effect, the hair can be attracted by the airflow and automatically adhere to and wrap around the outer surface of the two tube components, making the hair curled. The subsequent airflow can continue to blow towards the hair to heat and set the curled hair. This curling method can automatically curl hair, is simple to operate, and helps to improve the curling effect.

[0036] Moreover, at least a portion of the first airflow and at least a portion of the second airflow have opposite swirling directions, allowing for curling in different directions using airflows with different swirling directions, and the operation is convenient.

[0037] In addition, the structural design using two tubular components saves materials and reduces costs compared to the structure of a ring-shaped component. Furthermore, the two tubular components can be designed as two independent parts, with minimal influence between them, making them easy to improve and highly scalable.

[0038] Thirdly, a hair curling device is provided, including a hair dryer main unit and a hair curling attachment of either the first or the second aspect;

[0039] The hair dryer is detachably connected to the curling attachment via a connector; and the hair dryer is configured to provide fluid and allow the fluid to enter the interior of the curling attachment through an air inlet.

[0040] In some embodiments, the blower unit includes:

[0041] The handle has an internal air duct, and one end of the handle is connected to the connector so that the air duct is connected to the air inlet.

[0042] The air inlet is connected to the air duct and is located at the end of the handle away from the connector.

[0043] A fan, located within the air duct, is configured to draw fluid from outside the handle through the air inlet and deliver the fluid into the interior of the curling attachment via the air duct and air inlet.

[0044] In some embodiments, the hair dryer unit further includes:

[0045] A heating element is installed inside the air duct and is configured to heat the fluid flowing through the air duct.

[0046] In the above technical solution, the hair curling device includes a hair curling attachment of either the first aspect or the second aspect, and has the same technical effect as the hair curling attachments in the first aspect and the second aspect. Attached Figure Description

[0078] As part of the inventive concept of this disclosure, before describing the embodiments of this disclosure, it is necessary to analyze the reasons for the problems of complex operation and poor curling effect in related technologies, and obtain the technical solutions of the embodiments of this disclosure through reasonable analysis.

[0079] In related technologies, the development of hair styling tools has evolved from primitive tools to metal tools, electric tools, and then to modern, environmentally friendly tools. With the advancement and innovation of technology, especially the invention of the generator, electric hair styling tools have begun to emerge. These electric tools make hair trimming and styling more convenient and faster. Hair dryers, curling irons, and straighteners have become essential hair styling tools, not only better meeting people's needs for hairstyle styling but also being safer and more convenient. For curling devices, hair is generally curled and styled by manually clamping the hair and rotating the curling device, which is complicated to operate and produces poor curling results. Therefore, automatic curling devices have appeared on the market, but many technical pain points still exist: on the one hand, most curling attachments curl hair through simple physical clamping or rotation, failing to effectively utilize aerodynamic principles to optimize the curling effect; for example, in the curling process of traditional curling devices, the hair is prone to loosening and cannot tightly adhere to the curling attachment to form a lasting curl, mainly because of the lack of an airflow mechanism that can effectively guide the hair and make it adhere. On the other hand, existing curling attachments are usually single-function, only able to curl hair to the left or right. Consumers who want curls in different directions need to purchase multiple attachments, increasing costs. Moreover, in terms of the strength of hair suction and curling, existing products cannot meet consumers' needs for quick and efficient curling; ordinary airflow methods result in insufficient suction and curling power. Furthermore, existing curling attachments are limited in their styling versatility, making it difficult to flexibly switch between large and small curls on the same attachment, thus failing to meet consumers' diverse hairstyle needs.

[0080] To address this, the present disclosure provides a hair curling attachment and a hair curling device including the hair curling attachment. The hair curling attachment has multiple outlets, and under the guidance of the multiple outlets, the fluid forms an airflow that flows around the outer surface of the hair curling attachment. Based on the Coanda effect, the hair can be attracted by the airflow and automatically wrapped around the outer surface of the hair curling attachment to curl the hair and set it under the action of subsequent airflow, thereby solving the technical problems of complex hair curling operation and poor effect in the prior art.

[0081] The technical solutions of the embodiments of this disclosure are described in detail below with reference to the accompanying drawings. The technical features involved in the different embodiments of this disclosure described below can be combined with each other as long as they do not conflict with each other.

[0082] An embodiment of this disclosure provides a hair curling accessory 1, such as... Figures 1 to 5 as well as Figure 14 As shown, the hair curling accessory 1 includes a ring component 11 and a connector 12.

[0083] Regarding ring component 11, as follows Figures 1 to 4As shown, the ring component 11 is roughly in the shape of a circular ring, and an annular channel 1111 is formed inside the ring component 11. The annular channel 1111 extends along the circumferential direction A of the ring component.

[0084] Multiple outlets 113 are provided on the wall of the ring component 11. All outlets 113 are connected to the annular channel 1111, and the multiple outlets 113 are spaced apart along the circumferential direction B of the flow section of the annular channel.

[0085] Regarding connector 12, such as Figure 2 , Figure 3 and Figure 14 As shown, the connector 12 is disposed on the ring component 11. The connector 12 is mainly used to connect the ring component 11 to the hair dryer 2, that is, to realize the assembly between the hair curling accessory 1 and the hair dryer 2.

[0086] The connector 12 has an air inlet 121, which is connected to the annular channel 1111. The air inlet 121 serves as a guide to introduce fluid into the annular channel 1111. The fluid entering the annular channel 1111 flows out from multiple outlets 113.

[0087] The fluid flowing out through multiple outlets 113 is blown toward the outer surface 116 of the annular member and forms an airflow that flows around the outer surface 116 of the annular member, and at least part of the airflow flows around between the inner and outer sides of the outer surface 116 of the annular member.

[0088] It should be noted that the fluids flowing out of multiple outlets 113 converge to form an airflow. The airflow can be formed by the convergence of all the fluids flowing out of all outlets 113, or it can be formed by the convergence of some of the fluids flowing out of all outlets 113.

[0089] It should be further explained that, since an annular channel 1111 is formed on the annular member 11, the interior of the annular member 11 refers to the area where the annular channel 1111 is located. Correspondingly, the exterior of the annular member 11 refers to the area of ​​the annular member 11 exposed to the external environment. The exterior region of the annular member 11 is divided into an inner ring edge 114, an outer ring edge 115, and an outer surface 116 of the annular member located between the inner ring edge 114 and the outer ring edge 115. The inner side of the outer surface 116 of the annular member refers to the area of ​​the outer surface 116 of the annular member close to the inner ring edge 114, and the outer side of the outer surface 116 of the annular member refers to the area of ​​the outer surface 116 of the annular member close to the outer ring edge 115. Figure 2 As shown.

[0090] With the above structural design, multiple outlets 113 guide fluid to the outer surface 116 of the ring component, forming an airflow around the outer surface 116 of the ring component, and at least part of the airflow flows around the inner and outer sides of the outer surface 116 of the ring component. Based on the Coanda effect, hair can be attracted by the airflow and automatically adhere to and wrap around the outer surface 116 of the ring component, making the hair curled. Subsequent airflow can continue to blow on the hair to heat and set the curled hair. This curling method can automatically curl hair, is simple to operate, and helps to improve the curling effect.

[0091] Furthermore, by designing the hair curling attachment 1 as a ring-shaped component 11, the two airflows formed on opposite sides of the ring-shaped component 11 have opposite directions of rotation, allowing for curls in different directions using airflows with different rotational directions. For example, as Figure 5 As shown, the airflow directions on the left and right sides of the annular component 11 are opposite. The airflow on the left side of the annular component flows counterclockwise around the outer surface 116 of the annular component. When hair is placed on the left side of the annular component, based on the Coanda effect, the hair can be curled counterclockwise with the airflow (left curl). When hair is placed on the right side of the annular component, the airflow on the right side of the annular component flows clockwise around the outer surface 116 of the annular component. Based on the Coanda effect, the hair can be curled clockwise with the airflow (right curl). This structural design allows for easy implementation of left and right curling functions on the same curling attachment 1. Compared with traditional single-direction curling attachments 1, this greatly improves the versatility and practicality of the curling attachment 1 and is easy to operate.

[0092] In addition, the hair curling attachment 1 adopts the structure of a ring component 11, which helps to enhance the structural strength of the hair curling attachment 1, so as to support more hair to be wrapped around the outer surface 116 of the ring component, thereby improving the hair curling efficiency.

[0093] In some embodiments, such as Figures 2 to 4 as well as Figure 9 As shown, the so-called at least part of the airflow circulating between the inner and outer sides of the outer surface 116 of the annular member includes at least the following two cases.

[0094] One possible scenario is: such as Figures 2 to 4 As shown, multiple outlets 113 extend along the circumferential direction A of the annular member, so that at least part of the airflow formed by the fluid flowing out through the multiple outlets 113 flows around the outer surface 116 of the annular member along the circumferential direction B of the flow section of the annular channel.

[0095] By adopting the above structural design, the fluid can be guided to flow out from the outlets 113 and form an annular airflow around the outer surface 116 of the ring component through the arrangement of the multiple outlets 113. The annular airflow is based on the Coanda effect, which causes the hair to roll around the outer surface 116 of the ring component in a clockwise or counterclockwise direction to achieve curling.

[0096] Another possible scenario is: such as Figure 9 As shown, multiple outlets 113 are spirally extended along the outer surface 116 of the annular component, so that at least part of the airflow formed by the fluid flowing out through the multiple outlets 113 spirally flows around the outer surface 116 of the annular component along the circumferential direction A.

[0097] By employing the above structural design and strategically positioning multiple outlets 113, fluid can be guided to flow out from the outlets 113 and form a spiral airflow surrounding the outer surface 116 of the annular component. This spiral airflow, based on the Coanda effect, causes hair to spirally wrap around the outer surface 116 of the annular component, achieving a curling effect different from the previous case. Specifically, the degree and style of the hair curl are different, enriching the diversity of curling styles. Furthermore, compared to annular airflow, spiral airflow generates stronger suction, more effectively adhering the hair to the curling attachment 1 and tightly wrapping it, significantly enhancing the strength of hair suction and curling, and improving curling efficiency and effect.

[0098] Optionally, the number of exports 113 can be three, four, five, six, seven, eight, etc., and is not limited here; this embodiment is illustrated by taking six exports 113 as an example.

[0099] In some embodiments, the plane containing the flow section of the annular channel 1111 is a first plane, and there are multiple first planes; the annular component 11 is cut by multiple first planes to form multiple first cross-sections, such as... Figure 5 As shown; within the same first plane, the sum of the area of ​​the first cross section and the area of ​​the flow cross section of the annular channel 1111 is the first total area; wherein, at least two first total areas are different.

[0100] It should be understood that there is only one first cross section and one flow section of the annular channel 1111 in a first plane. The size of the first total area formed by the first cross section and the flow section of the annular channel 1111 can directly reflect the size of the circumference of the outer perimeter of the ring component 11. That is, a larger first total area can make the inner diameter of the hair curl larger, forming a large curl shape of hair. Conversely, a smaller first total area can make the inner diameter of the hair curl smaller, forming a small curl shape of hair.

[0101] Based on this, if at least two first total areas are different, it means that there are at least two places on the ring component 11 with different first total areas, which can then form two different curly hairstyles: large curls and small curls.

[0102] Furthermore, the connector 12 is connected to the outside of the ring member 11 along the top and bottom direction; the first total area increases along the left and right direction of the ring member 11; wherein the top and bottom direction of the ring member 11, the left and right direction of the ring member 11, and the axial direction C of the ring member are perpendicular to each other.

[0103] It should be understood that the first total area increasing along the left and right direction of the annular member 11 can mean that the first total area on the annular member 11 gradually increases from left to right, or it can mean that the first total area on the annular member 11 gradually increases from right to left. This embodiment will use the example of the first total area on the annular member 11 gradually increasing from left to right as an example.

[0104] Using the above structural design, such as Figure 10 As shown, the first total area on the ring component 11 gradually increases from left to right, so that the outer perimeter of the ring component from the left side L to the right side R gradually increases, thereby enabling the creation of various curl sizes (such as large, medium, and small curls with different inner diameters), allowing consumers to easily create large and small curls on the same curling attachment 1, enriching the diversity of curl styles.

[0105] In some embodiments, such as Figures 2 to 9 As shown, the annular component 11 includes an annular frame 111 and multiple blades 112. An annular channel 1111 is formed inside the annular frame 111, and multiple hole assemblies 1112 are formed in the annular frame 111 along the circumferential direction B of the flow section of the annular channel. The multiple blades 112 are connected to the outside of the annular frame 111 at intervals along the circumferential direction B of the flow section of the annular channel. The slit between two adjacent blades 112 forms an outlet 113, and the outlet 113 is connected to the annular channel 1111 through the hole assembly 1112.

[0106] It should be noted that there are at least two ways in which multiple blades 112 can be arranged on the annular frame 111.

[0107] I. For example Figures 2 to 4 As shown, multiple blades 112 are arranged sequentially along the circumferential direction B of the flow section of the annular channel, so that multiple outlets 113 extend along the circumferential direction A of the annular component to guide fluid out of the outlets 113 and form an annular airflow around the outer surface 116 of the annular component.

[0108] II. Figure 9As shown, multiple blades 112 are spirally arranged circumferentially along the flow section of the annular channel, so that multiple outlets 113 are spirally extended along the outer surface 116 of the annular component, so as to guide the fluid to flow out from the outlets 113 and form a spiral airflow around the outer surface 116 of the annular component.

[0109] Optionally, the number of blades 112 can be three, four, five, six, seven, eight, etc., and is not limited here; this embodiment takes six blades 112 as an example for illustration. After the six blades 112 are arranged on the ring frame 111, six outlets 113 can be formed.

[0110] Optionally, such as Figure 7 As shown, the multiple blades 112 and the ring frame 111 are separate structures, and the multiple blades 112 and the ring frame 111 can be connected by plug-in or by bolt assembly locking. The separate structure design facilitates the production and processing of the product.

[0111] Optionally, such as Figure 8 As shown, the ring frame 111 is divided into two detachable semi-ring structures 1113 along its axial direction. Designing the ring frame 111 as two semi-ring structures 1113 facilitates mold making and processing of the product. Furthermore, the two semi-ring structures 1113 can be assembled using plug-in methods, making installation convenient.

[0112] Of course, each semi-ring structure 1113 can be integrally made with corresponding blades 112. This structural design can complete the assembly of the entire hair curling accessory 1 by assembling the two semi-ring structures 1113, which has high assembly efficiency.

[0113] Optionally, such as Figure 7 As shown, multiple reinforcing members 1121 are spaced apart along the circumferential direction A of the annular component on the blade 112. These reinforcing members 1121 extend from one end of the blade 112 near the annular frame 111 into the outlet 113. The reinforcing members 1121 enhance the structural strength of the blade 112. Furthermore, by designing the reinforcing members 1121 within the slit between adjacent blades 112, they can guide the flow direction of the fluid within the outlet 113, minimizing interference between the fluid on both sides of the reinforcing members 1121 and creating a more stable airflow.

[0114] Optionally, such as Figure 6 and Figure 7 As shown, the hole assembly 1112 includes multiple grid holes arranged circumferentially along the annular frame 111. The grid hole design allows fluid to enter from the annular channel 1111 to the outlet 113 while ensuring the structural strength of the annular frame 111.

[0115] The embodiments of this disclosure also provide a hair curling accessory 1, such as Figure 11 and Figure 12 As shown, the hair curling accessory 1 includes a connector 12 and a first tube component 13 and a second tube component 14 that are connected to the connector 12 and spaced apart from each other.

[0116] The connector 12 has an air inlet configured to guide fluid into the inner cavity of the first tube component 13 and the inner cavity of the second tube component 14.

[0117] The first tube component 13 has a plurality of first air outlets communicating with its inner cavity. The plurality of first air outlets are arranged at intervals along the circumferential direction D of the first tube component and guide fluid to be blown out along the outer surface of the first tube component 13 to form a first airflow flowing around the outer surface of the first tube component 13.

[0118] The first airflow flows around the outer surface of the first tube component 13 in the circumferential direction D, so that the first airflow forms an annular airflow; or, the first airflow flows spirally around the outer surface of the first tube component 13 in the extending direction F, so that the first airflow forms a spiral airflow.

[0119] It should be noted that one end of the first tube component 13 in its extension direction F is connected to the air inlet of the connector 12, and the other end is blocked to guide the fluid to flow out from the inner cavity of the first tube component 13 through a plurality of first air outlets.

[0120] The second tube component 14 has a plurality of second air outlets communicating with its inner cavity. The plurality of second air outlets are spaced apart along the circumferential direction E of the second tube component and guide fluid to be blown out along the outer surface of the second tube component 14 to form a second airflow flowing around the outer surface of the second tube component 14.

[0121] The second airflow flows around the outer surface of the second tube component 14 in the circumferential direction E, so that the second airflow forms an annular airflow; or, the second airflow flows spirally around the outer surface of the second tube component 14 in the extension direction G, so that the second airflow forms a spiral airflow.

[0122] It should be noted that one end of the second tube component 14 in its extension direction G is connected to the air inlet of the connector 12, and the other end is blocked to guide the fluid to flow out from the inner cavity of the second tube component 14 through a plurality of second air outlets.

[0123] By adopting the above structural design, two tube components (a first tube component 13 and a second tube component 14) are set, and multiple air outlets (multiple first air outlets and multiple second air outlets) are opened on the two tube components. Fluid can be guided to blow onto the outer surface of the two tube components, forming a first airflow and a second airflow flowing around the outer surface of the two tube components. Based on the Coanda effect, hair can be attracted by the airflow and automatically adhere to and wrap around the outer surface of the two tube components, making the hair curled. Subsequent airflow can continue to blow onto the hair to heat and set the curled hair. This curling method can automatically curl hair, is simple to operate, and helps to improve the curling effect.

[0124] Moreover, the structural design of two tubular components saves materials and reduces costs compared to the structure of ring component 11. Furthermore, the two tubular components can be designed as two independent parts, with little influence between them, making them easy to improve and highly scalable.

[0125] Furthermore, at least a portion of the first airflow flows in the opposite direction to at least a portion of the second airflow.

[0126] By employing the above structural design, at least a portion of the first airflow and at least a portion of the second airflow have opposite swirling directions. Different swirling airflow directions allow for curling in different directions, and the operation is convenient. For example, the first airflow flows counter-clockwise around the outer surface of the first tube component 13. When hair is placed on one side of the first tube component 13, based on the Coanda effect, the hair can be curled counter-clockwise with the airflow (left curl). The second airflow flows clockwise around the outer surface of the second tube component 14. When hair is placed on one side of the second tube component 14, based on the Coanda effect, the hair can be curled clockwise with the airflow (right curl). This structural design allows for easy left and right curling functions on the same curling attachment 1. Compared to traditional single-direction curling attachments 1, this greatly improves the versatility and practicality of the curling attachment 1, and is also convenient to operate.

[0127] Furthermore, the first tube component 13 and the second tube component 14 are respectively disposed on both sides of the axis of the connector 12.

[0128] Furthermore, the first pipe component 13 and the second pipe component 14 can both vent air simultaneously or separately (i.e., they do not vent air at the same time).

[0129] Furthermore, such as Figure 13 As shown, the maximum outer diameter of the first tube component 13 is different from the maximum outer diameter of the second tube component 14.

[0130] It should be understood that the maximum outer diameter of the first tube component 13 and the second tube component 14 can directly reflect the size of the circumference of the outer perimeter of these two tube components; that is, a larger maximum outer diameter of the tube component can make the inner diameter of the hair curl larger, forming a large curl style of hair, and conversely, a smaller maximum outer diameter of the tube component can make the inner diameter of the hair curl smaller, forming a small curl style of hair.

[0131] Based on this, the difference in the maximum outer diameter of the first tube component 13 and the second tube component 14 indicates that these two tube components can be used to form two different curly hairstyles: large curls and small curls. This allows consumers to easily create large curls and small curls on the same curling attachment 1, enriching the diversity of curly hairstyles.

[0132] Optionally, the first tube component 13 and the second tube component 14 can be straight tubes or curved tubes. The first tube component 13 and the second tube component 14 can adopt different tube shapes to create different curly hairstyles, enriching the diversity of hair styling.

[0133] It should be noted that the ends of the first pipe component 13 and the second pipe component 14 furthest from the connector 12 may or may not be connected. If the ends of the first pipe component 13 and the second pipe component 14 furthest from the connector 12 are connected, the product becomes... Figure 1 , 2 The form shown in Figure 10; if the ends of the first tube member 13 and the second tube member 14 furthest from the connector 12 are not connected, the product becomes Figure 12 , 13 The shape shown.

[0134] This disclosure also provides a hair curling device in its embodiments, such as... Figure 14 and Figure 15 As shown, the hair curling device includes a hair dryer 2 and a hair curling attachment 1 from any of the above embodiments. The hair dryer 2 is detachably connected to the hair curling attachment 1 via a connector 12; and the hair dryer 2 is configured to provide fluid and allow the fluid to enter the interior of the hair curling attachment 1 through an air inlet 121.

[0135] Optionally, the hair dryer 2 and the curling attachment 1 can be assembled using a snap-fit ​​or threaded connection. For example, a groove can be provided on the outer peripheral wall of the lower end of the connector 12, and an elastic block can be provided on the inner peripheral surface of the upper end of the hair dryer 2. The lower end of the connector 12 can extend into the upper interior of the hair dryer 2, and the installation between the hair dryer 2 and the curling attachment 1 can be achieved by screwing the elastic block into the groove. Alternatively, an external thread can be provided on the outer peripheral wall of the lower end of the connector 12, and an internal thread can be provided on the inner peripheral surface of the upper end of the hair dryer 2. The lower end of the connector 12 can extend into the upper interior of the hair dryer 2, and the installation between the hair dryer 2 and the curling attachment 1 can be achieved by the mating connection of the external and internal threads.

[0136] Furthermore, such as Figure 14 and Figure 15 As shown, the blower unit 2 includes a handle 21, an air inlet 22, and a fan 23.

[0137] The handle 21 has an internal air duct 211, and one end of the handle 21 is connected to the connector 12, so that the air duct 211 is connected to the air inlet 121.

[0138] Alternatively, the handle 21 is generally a cylindrical structure with an internal cavity.

[0139] The handle 21 has an air inlet 22 on its outer peripheral wall, and the air inlet 22 is connected to the air duct 211.

[0140] Optionally, the air inlet 22 is formed at the end of the handle 21 away from the connector 12.

[0141] The fan 23 is disposed in the air duct 211 and is configured to draw fluid from outside the handle 21 through the air inlet 22 and send the fluid into the interior of the hair curling attachment 1 through the air duct 211 and the air inlet 121.

[0142] Alternatively, fan 23 can be an axial fan or a centrifugal fan.

[0143] It should be understood that the appropriate type of fan 23 can be selected based on factors such as product positioning, performance requirements, and cost, and there are no restrictions here.

[0144] Furthermore, the blower unit 2 also includes a heating element (not shown in the figure), which is disposed within the air duct 211 and configured to heat the fluid flowing through the air duct 211. The heating element is located downstream of the fan 23 along the direction of airflow within the air duct 211.

[0145] Optionally, the heating element can be a nickel-chromium wire heating element, a PTC ceramic heating element, an aluminum sheet heating element, etc.

[0146] It should be understood that the appropriate type of heating element can be selected based on factors such as product positioning, performance requirements, and cost, and there are no restrictions here.

[0147] Of course, the hair dryer 2 also has a control unit and buttons. Input is made through the buttons to control the opening and closing of the fan 23 and its speed, as well as the opening and closing and working status of the heating element, thereby controlling the air volume and heat of the curling device. Based on this, multiple working modes can be set for the curling device.
