Technical Field

[0001] This utility model relates to the field of hair care technology, and in particular to a nozzle accessory and hair care device. Background Technology

[0002] Existing hair care devices generally include various types of nozzle attachments, allowing users to choose which type to use for drying or styling their hair. Nozzle attachments for straightening hair have a cavity; during use, the hair is placed inside, heated by the airflow, and the nozzle attachment is moved to straighten the hair. However, during use, the airflow inside the cavity can easily overflow from the end, causing hair to drift out and affecting the straightening effect. Utility Model Content

[0003] The purpose of this invention is to provide a nozzle accessory that can prevent hair from blowing outwards.

[0004] The nozzle accessory provided in one embodiment of this utility model includes: First shell section; A second housing portion is provided at a distance from the first housing portion to form a receiving cavity for receiving hair, the receiving cavity extending through in a first direction; An airflow chamber is disposed within the first housing portion and / or the second housing portion; The first housing portion has a first wall defining the receiving cavity, and the second housing portion has a second wall defining the receiving cavity. The first wall and / or the second wall are provided with an air outlet communicating with the airflow chamber. The first wall is provided with a first constraint portion protruding toward the second wall, and the second wall is provided with a second constraint portion protruding toward the first wall. The extending directions of the first constraint portion and the second constraint portion are at an angle to the first direction, and the first constraint portion and the second constraint portion are arranged alternately along the first direction.

[0005] In this embodiment, by providing a first constraint part and a second constraint part, some airflow can be blocked from overflowing, thus restraining the hair and preventing it from spilling out of the receiving cavity. Furthermore, it can restrain and gather the hair, thereby improving the straightening effect.

[0006] As a further improvement of one embodiment of the present invention, the extending directions of the first constraint portion and the second constraint portion are perpendicular to the first direction.

[0007] This implementation method is easier for users to use and provides better direct hair output.

[0008] As a further improvement of one embodiment of the present invention, the distance between the first constraint portion and the second constraint portion along the first direction is 3-6 mm.

[0009] This embodiment can ensure a good gathering effect on the hair while avoiding any impact on the placement of the hair, allowing the hair in the same area to stay appropriately between the first and second restraint parts, thereby enhancing the straightening effect.

[0010] As a further improvement of one embodiment of the present invention, along the first direction, the receiving cavity has a first end and a second end opposite to each other, a guide plate is provided at the air outlet, the guide plate is inclined toward the second end, and the first constraint part and the second constraint part are disposed near the first end relative to the guide plate.

[0011] In this embodiment, the first and second constraint parts can prevent airflow toward the first end, thereby preventing the hair from drifting toward the first end. Simultaneously, during use, the hair near the second end is first heated by the airflow from the vent, and then restrained and gathered by the first and second constraint parts located at the first end, resulting in better straightening.

[0012] As a further improvement of one embodiment of the present invention, the first housing portion and the second housing portion are spaced apart along a third direction, and the distance between the first constraint portion and the second constraint portion along the third direction is less than 2mm.

[0013] In this embodiment, the hair can be sufficiently constrained between the first and second constraint parts, resulting in a more significant straightening effect.

[0014] As a further improvement of one embodiment of the present utility model, the second wall is provided with the air outlet, and the distance between the air outlet and the second constraint part along the first direction is greater than 3mm, and the first constraint part is disposed closer to the first end relative to the second constraint part.

[0015] In this embodiment, vortex disturbances caused by the first and second constraint parts to the airflow exiting the outlet can be avoided. Vortex disturbances may affect the uniformity and stability of the airflow, thereby affecting the direct-flow effect.

[0016] As a further improvement of one embodiment of the present invention, the first constraint portion gradually tapers from one end near the first wall toward the receiving cavity, and / or the second constraint portion gradually tapers from one end near the second wall toward the receiving cavity, and the end faces of the first constraint portion and / or the second constraint portion near the receiving cavity are planar or arc-shaped.

[0017] The technical solution in this embodiment helps guide the airflow to pass through the constraint part more smoothly, reduces the turbulence and resistance of the airflow near the constraint part, and thus further improves the uniformity and stability of the airflow.

[0018] As a further improvement of one embodiment of the present invention, the first housing portion and the second housing portion are spaced apart along a third direction, and the height of the first constraint portion and / or the second constraint portion along the third direction is less than 5mm.

[0019] The design in this embodiment is ergonomic, easy for users to use, and provides good straight hair results.

[0020] As a further improvement of one embodiment of the present invention, the distance between the first housing portion and the second housing portion is 5-8mm.

[0021] The technical solution of this embodiment is convenient for users to place hair into the cavity, and ensures that the airflow fills the entire area of ​​the cavity, preventing the airflow from overflowing from the cavity, thereby ensuring the straightening effect.

[0022] The air inlet and airflow chamber provided in this embodiment have, along the first direction, a first end and a second end opposite to each other, the receiving cavity gradually expanding toward the first end near the first end, and / or the receiving cavity gradually expanding toward the second end near the second end.

[0023] The technical solution of this embodiment makes it easy for users to put hair into the receiving cavity.

[0024] As a further improvement of one embodiment of the present invention, the first wall and / or the second wall includes at least two air guide plates, the at least two air guide plates are staggered to form the air outlet, and the staggered portions of the at least two air guide plates are parallel.

[0025] The nozzle accessory provided in this embodiment can make the airflow more uniform and the airflow distribution more reasonable, thereby improving the straightening effect.

[0026] As a further improvement of one embodiment of the present invention, the angle between the intersecting portions of at least two of the air guide plates and the first direction is 0-15°.

[0027] In this embodiment, the angle design between the intersecting portions of adjacent air guide plates and the first direction further optimizes the airflow direction. This ensures that the airflow can pass smoothly through the air outlet while avoiding airflow loss or changes in flow direction caused by excessive angles, thus ensuring the stability and reliability of the direct hair drying effect.

[0028] As a further improvement of one embodiment of the present invention, the first wall and / or the second wall are provided with at least two air outlets, the at least two air outlets are arranged at intervals along the first direction, and the extension direction of the air outlets is at an angle to the first direction; at least two partitions are provided at intervals in each air outlet; the positions of the partitions in two adjacent air outlets are relatively staggered.

[0029] The technical solution of this embodiment can increase the air volume, so that the airflow can fill the entire cavity as much as possible, thereby improving the straightening effect on the hair; each air outlet is equipped with a separator, which can guide and disperse the airflow, making the airflow distribution more uniform and avoiding the phenomenon of hair strands caused by concentrated airflow.

[0030] As a further improvement of one embodiment of the present invention, the receiving cavity has a front end and a rear end, the front end being open to allow hair to enter, and a first air distribution member is provided in the airflow cavity. The first air distribution member extends at least in the component of the first direction along the extension direction of the air outlet, and the distance between the first air distribution member and the front end of the air outlet is less than half the length of the air outlet.

[0031] In this embodiment, by setting the first air distribution component, the airflow in the airflow chamber can be further blocked, thereby further reducing the airflow in the front area and minimizing the airflow in the front area, thus preventing hair from drifting out from the front of the receiving cavity.

[0032] As a further improvement of one embodiment of the present invention, a second air distribution component is also provided in the airflow chamber, and the second air distribution component is spaced apart from the first air distribution component along the extension direction of the air outlet.

[0033] In this embodiment, by setting a second air distribution component, the airflow flowing into the front area can be further blocked, thereby reducing the air volume in the front area.

[0034] This utility model also provides a hair care device, including a main unit and a nozzle accessory as described in any of the above embodiments, wherein the nozzle accessory is detachably connected to the main unit.

[0035] The nozzle accessory and hair care device provided by this utility model have a first restraining part and a second restraining part alternately arranged on the two opposing cavity walls of the receiving cavity. The first restraining part and the second restraining part can block the airflow and prevent hair from floating out of the receiving cavity. At the same time, the first restraining part and the second restraining part restrain the hair, resulting in better straightening effect. Moreover, the alternating arrangement of the first restraining part and the second restraining part makes it easy for the user to place the hair into the receiving cavity.

Detailed Implementation

[0037] The following detailed description incorporates the accompanying drawings, which form part of this specification. The illustrative embodiments mentioned in the specification and drawings are for illustrative purposes only and are not intended to limit the scope of this application. Those skilled in the art will understand, based on the teachings of this application, that many other embodiments can be employed and various changes can be made to the described embodiments without departing from the spirit and scope of this utility model. It should be understood that the various aspects of this application illustrated herein can be arranged, substituted, combined, separated, and designed in many different configurations, all of which are within the scope of this application.

[0038] This utility model provides a nozzle attachment and a hair care device. The hair care device may include a hair dryer and a hair styling tool. The nozzle attachment is used for straightening hair. The hair care device includes a main unit, and the nozzle attachment is detachably connected to the main unit. When a user needs to straighten their hair, they can choose to attach the nozzle attachment to the main unit.

[0039] In one embodiment, the diameter / shape of the nozzle accessory is consistent with the diameter / shape of the hair care device main unit, and the outer contours of the two can be basically flush, thereby improving the aesthetic appearance and making it easier for users to disassemble and use.

[0040] See Figures 1 to 3 The nozzle accessory provided by this utility model includes a first housing portion 11 and a second housing portion 12. The second housing portion 12 is spaced apart from the first housing portion 11 to form a receiving cavity 13 for receiving hair. The receiving cavity 13 extends through the nozzle along a first direction X1.

[0041] The nozzle accessory has an air inlet 3 and an air outlet 2. When the nozzle accessory is connected to the main unit of the hair care device, the airflow inside the main unit of the hair care device enters the nozzle accessory from the air inlet 3 and is then blown out from the air outlet 2.

[0042] In the first embodiment of this utility model, the first direction X1 is perpendicular to the axial direction of the air inlet 3. Of course, the receiving cavity 13 can also be an inclined cavity. When the receiving cavity 13 is an inclined cavity, the first direction X1 can form an acute angle with the axial direction of the air inlet 3.

[0043] In this embodiment, the nozzle accessory further includes an airflow chamber 14. The airflow chamber 14 is disposed within the first housing portion 11 and / or the second housing portion 12.

[0044] It is understood that the airflow chamber 14 may be formed only in the first housing portion 11, or only in the second housing portion 12, or, as in the provided specific embodiment, both the first housing portion 11 and the second housing portion 12 may have an airflow chamber 14. The airflow chamber 14 is used to guide and regulate the airflow blown out from the main body of the hair care device, so that it can be distributed more evenly, thereby enhancing the blowing effect.

[0045] An air outlet 2 is provided on the wall of the receiving cavity 13 formed by the first housing portion 11 and / or the second housing portion 12. The air outlet 2 communicates with the airflow chamber 14.

[0046] Specifically, the first housing portion 11 has a first wall 111 defining a receiving cavity 13. The second housing portion 12 has a second wall 121 defining a receiving cavity 13. The first wall 111 and the second wall 121 are opposite to each other and are spaced apart to form the receiving cavity 13.

[0047] The first wall 111 and / or the second wall 121 are provided with air outlets 2. This can be understood as the first wall 111 being provided with air outlets 2, the second wall 121 being provided with air outlets 2, or both the first wall 111 and the second wall 121 being provided with air outlets 2.

[0048] In the specific embodiment provided by this utility model, both the first housing part 11 and the second housing part 12 are provided with airflow chambers 14, the first wall 111 is provided with an air outlet 2, and the second wall 121 is also provided with an air outlet 2. In this way, both walls forming the receiving cavity 13 are provided with air outlets 2, and the blown air is more uniform.

[0049] In this embodiment, the first wall 111 is provided with a first constraint portion 5 protruding toward the second wall 121. The second wall 121 is provided with a second constraint portion 6 protruding toward the first wall 111. The extending directions of the first constraint portion 5 and the second constraint portion 6 are at an angle to the first direction X1. The first constraint portion 5 and the second constraint portion 6 are staggered along the first direction X1.

[0050] In this embodiment, the first constraint part 5 can be integrally formed with the first wall 111, and the second constraint part 6 can be integrally formed with the second wall 121. The extending directions of the first constraint part 5 and the second constraint part 6 can be substantially the same as the extending directions of the first wall 111 and the second wall 121. The extending directions of the first constraint part 5 and the second constraint part 6 can be the same or different.

[0051] In a specific embodiment, the first constraint part 5 and the second constraint part 6 extend in the same direction. The extension directions of the first constraint part 5 and the second constraint part 6 are perpendicular to the first direction X1.

[0052] In this embodiment, the extending directions of the first constraint part 5 and the second constraint part 6 can be defined as the second direction X2.

[0053] When a user uses the nozzle attachment to straighten their hair, the hair entering the receiving cavity 13 will partially block the air outlet 2, causing the airflow in the receiving cavity 13 to overflow towards the opening of the first end 133 or the second end 134 of the receiving cavity 13. This causes the hair in the receiving cavity 13 to drift towards the first end 133, thus affecting the straightening effect.

[0054] In this embodiment, the first constraint part 5 and the second constraint part 6 can block some airflow from overflowing, thus restraining the hair and preventing hair from overflowing from the receiving cavity 13. Simultaneously, when using this nozzle accessory, the user typically uses the hair-styling device to heat the hair while moving it downwards along the direction of the hair strand to straighten the hair. During use, the first constraint part 5 and the second constraint part 6 can restrain and gather the hair, thereby improving the straightening effect.

[0055] The first constraint part 5 and the second constraint part 6 are staggered along the first direction X1, making it easier for the user to put hair into the receiving cavity 13 without affecting the amount of hair put into the receiving cavity 13. During use, hair in the same area passes through the first constraint part 5 and the second constraint part 6 in sequence, which can increase the straightening effect.

[0056] Furthermore, in one embodiment, the distance between the first constraint portion 5 and the second constraint portion 6 along the first direction X1 is 3 to 6 mm. Preferably, the distance between the first constraint portion 5 and the second constraint portion 6 is 5.5 mm.

[0057] If the distance between the first constraint part 5 and the second constraint part 6 is too large, the hair gathering effect will be poor. If the distance between the first constraint part 5 and the second constraint part 6 is too small, it will affect the placement of the hair, and the hair in the same area will pass through the first constraint part 5 and the second constraint part 6 quickly, resulting in poor straightening effect of the first constraint part 5 and the second constraint part 6.

[0058] In this embodiment, the distance between the first constraint part 5 and the second constraint part 6 is set to 3-6mm. This ensures a good gathering effect on the hair while avoiding any impact on the placement of the hair. This allows the hair in the same area to stay appropriately between the first constraint part 5 and the second constraint part 6, thereby enhancing the straightening effect.

[0059] Furthermore, in combination Figure 4 In one embodiment of this utility model, along the first direction, the receiving cavity 13 has a first end 133 and a second end 134 facing each other. An air guide plate 4 is provided at the air outlet 2, and the air guide plate 4 is inclined towards the second end 134. In this way, the airflow can be guided towards the second end 134, improving the efficiency of using the nozzle accessory for styling.

[0060] In this embodiment, the first constraint part 5 and the second constraint part 6 are disposed near the first end 131 relative to the air guide plate 4.

[0061] In this embodiment, the first restraining part 5 and the second restraining part 6 are disposed near the first end 133 relative to the air guide plate 4. Therefore, the first restraining part 5 and the second restraining part 6 can prevent the airflow toward the first end 133, thereby preventing the hair from drifting toward the first end 133. At the same time, during use, the hair near the second end 134 is first heated by the airflow flowing from the air outlet 2, and then restrained and gathered by the first restraining part 5 and the second restraining part 6 disposed at the first end 133, resulting in a better straightening effect.

[0062] Furthermore, in one embodiment of the present invention, the first housing portion 11 and the second housing portion 12 are spaced apart along a third direction X3, and the distance between the first constraint portion 5 and the second constraint portion 6 along the third direction X3 is less than 2mm.

[0063] Preferably, the distance between the first constraint part 5 and the second constraint part 6 is 1.1 mm.

[0064] Among them, the third direction X3 can be perpendicular to the first direction X1.

[0065] This design ensures that the hair is sufficiently constrained between the first constraint part 5 and the second constraint part 6, resulting in a more pronounced straightening effect. If the distance is too large, the hair may not be effectively constrained within the receiving cavity 13, leading to a poor straightening effect.

[0066] If the distance is too small, it may make it difficult to place the hair or even damage it.

[0067] Therefore, setting the distance between the first constraint part 5 and the second constraint part 6 to less than 2mm, preferably 1.1mm, can both apply sufficient constraint to the hair in the receiving cavity 13 to ensure the straight hair effect and make it easier for the user to put the hair into the receiving cavity 13, resulting in a better user experience.

[0068] In one embodiment, the second wall 121 has an air outlet 2. Along the first direction X1, the distance between the air outlet 2 and the second constraint portion 6 is greater than 3 mm. The first constraint portion 5 is disposed near the first end 133 relative to the second constraint portion 6.

[0069] In this embodiment, the distance between the first constraint part 5 and the air outlet 2 closest to the first end 133 on the first wall 111 is greater than 3mm, and the distance between the second constraint part 6 and the air outlet 2 closest to the first end 133 on the second wall 121 is also greater than 3mm.

[0070] In this way, the first constraint part 5 and the second constraint part 6 can be prevented from causing vortex disturbances in the airflow exiting the air outlet 2. Vortex disturbances may affect the uniformity and stability of the airflow, thereby affecting the direct-flow effect.

[0071] By ensuring an appropriate distance between the first constraint part 5 and the second constraint part 6 and the air outlet 2, the airflow can flow more smoothly and act evenly on the hair, which not only improves the straightening efficiency but also ensures the stability of the straightening effect. In addition, this layout also helps to reduce noise and vibration that may be generated during use, further enhancing the user experience.

[0072] Furthermore, in one embodiment of this utility model, the first constraint portion 5 gradually tapers from the end near the first wall 111 toward the receiving cavity 13, and / or the second constraint portion 6 gradually tapers from the end near the second wall 121 toward the receiving cavity 13. The end faces of the first constraint portion 5 and / or the second constraint portion 6 near the receiving cavity 13 are planar or curved.

[0073] The tapered design of the first constraint section 5 and / or the second constraint section 6 helps guide the airflow more smoothly through the constraint section, reducing turbulence and resistance in the vicinity of the constraint section, thereby further improving the uniformity and stability of the airflow.

[0074] When the end faces of the first constraint part 5 and / or the second constraint part 6 near one end of the receiving cavity 13 are flat, it can be ensured that the airflow has a consistent direction and speed, which is crucial for achieving a uniform straight hair effect.

[0075] When the end face is designed as a curved surface, it can disperse the airflow to a certain extent, reducing the direct impact of the airflow on the hair, making the straightening process gentler and reducing damage to the hair. This design not only improves the efficiency and quality of straightening, but also fully considers the user's comfort and hair protection.

[0076] Along the first direction X1, the height of the end face of the first constraint part 5 and / or the second constraint part 6 is 0-1.5mm, preferably 0.3mm. This ensures that the first constraint part 5 and the second constraint part 6 have sufficient working length with the hair, resulting in a better straightening effect during the hair straightening process.

[0077] Furthermore, in one embodiment of this utility model, the height of the first constraint part 5 and / or the second constraint part 6 along the third direction X3 is less than 5mm.

[0078] Preferably, the height of the first constraint part 5 and / or the second constraint part 6 is 2 mm.

[0079] In this way, the first constraint part 5 and the second constraint part 6 can avoid occupying too much space in the receiving cavity 13, which would make the receiving cavity 13 too large and prevent the airflow from filling the entire receiving cavity 13, thus affecting the straightening effect. In addition, if the height of the first constraint part 5 and the second constraint part 6 is too large, the airflow will also encounter greater resistance when passing through, which will not only increase energy consumption, but may also cause uneven airflow, affecting the final straightening effect.

[0080] Furthermore, in one embodiment of this utility model, the distance between the first housing portion 11 and the second housing portion 12 is 5 to 8 mm.

[0081] The distance between the first housing portion 11 and the second housing portion 12, that is, the interval between the first wall 111 and the second wall 121, can be considered as the width of the receiving cavity 13.

[0082] Specifically, the distance between the first housing portion 11 and the second housing portion 12 can be measured along a third direction X3. The first direction X1, the second direction X2, and the third direction X3 can be perpendicular to each other.

[0083] If the width of the receiving cavity 13 is too small, it is difficult for the user to place hair into the receiving cavity 13, and the amount of hair that the receiving cavity 13 can hold is small, which is inconvenient for the user. If the width of the receiving cavity 13 is too large, the airflow blown from the air outlet 2 cannot fill the entire area of ​​the receiving cavity 13, and the airflow is easy to overflow from the receiving cavity 13, resulting in poor hair straightening effect and affecting the user's use.

[0084] Setting the distance between the first housing part 11 and the second housing part 12 to 5-8mm facilitates the user placing hair into the receiving cavity 13 while ensuring that airflow fills the entire area of ​​the receiving cavity 13, preventing airflow from overflowing and thus guaranteeing the straightening effect and improving the user experience. Furthermore, this distance range also allows for a more compact overall design of the hair care device accessories, making them easier to carry and use, while maintaining the straightening effect.

[0085] Preferably, the distance between the first housing portion 11 and the second housing portion 12 is 6mm, which can maximize the balance between ease of use and hair straightening effect.

[0086] Combination Figure 1 and Figure 3 In one embodiment, along the first direction X1, the receiving cavity 13 has a first end 133 and a second end 134 opposite to each other. The receiving cavity 13 gradually expands toward the first end 133 near the first end 133, and / or the receiving cavity 13 gradually expands toward the second end 134 near the second end 134.

[0087] It is understood that the receiving cavity 13 may expand towards the first end 133 only near the first end 133, or expand towards the second end 134 only near the second end 134, or expand towards the first end 133 and the second end 134 simultaneously near the first end 133 and the second end 134 respectively.

[0088] This design makes it easy for users to put their hair into the receiving cavity 13.

[0089] In a specific embodiment, the receiving cavity 13 gradually expands towards the first end 133 and the second end 134 near the first end 133 and the second end 134, respectively. This facilitates use by the user with either hand, improving ease of use. The angle at which the receiving cavity 13 gradually expands towards the first end 133 and the second end 134 can be the same or different, and can be designed according to the user's actual usage habits and needs.

[0090] Preferably, the accommodating cavity 13 expands at the same angle toward the first end 133 and the second end 134. This makes the shape of the accommodating cavity 13 more regular, which is convenient for processing and manufacturing, and also ensures that users can have the same user experience regardless of whether they use it with their hands.

[0091] Furthermore, the shape of the receiving cavity 13, which gradually expands toward the first end 133 and the second end 134, can be an arc, a parabola, or other shapes, as long as it can meet the user's need to smoothly put the hair into the receiving cavity 13.

[0092] See Figure 4Furthermore, in one embodiment of this utility model, the first wall 111 and / or the second wall 121 include at least two air guide plates 4. The at least two air guide plates 4 are spaced apart along a first direction X1, and adjacent air guide plates 4 are staggered to form air outlets 2. The staggered portions of adjacent air guide plates 4 are parallel.

[0093] The two adjacent air guide plates 4 are staggered, with partial overlap between the two adjacent air guide plates 4.

[0094] Preferably, two adjacent air guide plates 4 overlap by 0.5mm. This makes the airflow more uniform and the airflow distribution more reasonable, thereby improving the straightening effect.

[0095] In one embodiment, the angle between the intersecting portions of two adjacent air guide plates 4 and the first direction X1 is 0-15°.

[0096] The angle between the intersecting portions of the adjacent air guides 4 and the first direction X1 further optimizes the airflow direction. The airflow blowing obliquely towards the hair has a component perpendicular to the hair's extension direction and a component parallel to the hair's extension direction. In this embodiment, the angle between the intersecting portions of the adjacent air guides 4 and the first direction X1 is set between 0-15°, with a larger component of the airflow parallel to the hair's extension direction. This smooths and guides the hair cuticles to adhere closely to the hair shaft, effectively preventing frizz and static electricity. Therefore, it greatly reduces physical damage to the hair cuticles, providing a gentler styling method and resulting in smoother hair.

[0097] Furthermore, this angle setting allows airflow to pass smoothly through the air outlet 2 while avoiding airflow loss or changes in flow direction caused by an excessively large angle, ensuring the stability and reliability of the direct-flow effect. At the same time, tilting the air guide plate 4 also makes it easier to reserve a draft angle during manufacturing and processing, thus facilitating demolding from the mold.

[0098] In one embodiment, the air guide plate 4 protrudes into the airflow chamber 14 on the side connected to the first wall 111 or the second wall 121, thereby guiding the airflow evenly to the air outlet 2. The outer wall surface of the free end of the air guide plate 4 is arc-shaped, which can prevent noise generation and also generate the Coanda effect, making the airflow flow closer to the wall.

[0099] Further, see Figure 5 In one embodiment of this utility model, the first wall 111 and / or the second wall 121 are provided with at least two air outlets 2. The at least two air outlets 2 are spaced apart along the first direction X1.

[0100] It is understandable that multiple air outlets 2 can be provided only on the first wall 111, or multiple air outlets 2 can be provided on the second wall 121, or multiple air outlets 2 can be provided on both the first wall 111 and the second wall 121. The multiple air outlets 2 are arranged at intervals along the first direction X1, which can make the airflow blow out more evenly, thereby improving the treatment effect on the hair.

[0101] The air outlet 2 can be elongated. The extension direction of the air outlet 2 can be perpendicular to the first direction X1 or at a certain angle to the first direction X1, so as to adapt to the airflow guidance needs in different directions.

[0102] In a specific implementation, the extension direction of the air outlet 2 can be parallel to the second direction X2.

[0103] See Figure 4 In this embodiment, each air outlet 2 is provided with a partition 21. The partition 21 divides the air outlet 2 into at least two sub-air outlets 22 along the extension direction of the air outlet 2.

[0104] In this embodiment, by providing at least two air outlets 2 along the first direction X1, the air outlet area and air volume can be increased. By providing a separator 21 inside the air outlet 2, the airflow flowing out of the airflow chamber 14 can be evenly dispersed when passing through the air outlet 2. This improves the uniformity of the airflow and helps reduce airflow turbulence, preventing airflow concentration at the air outlet 2 from causing hair tangles. Consequently, the straightened hair after styling achieves a better effect. At the same time, more uniform airflow also prevents hair from detaching from the receiving cavity 13.

[0105] In one embodiment, at least two partitions 21 are provided inside the air outlet 2. The at least two partitions 21 are spaced apart along the extending direction of the air outlet 2. The positions of the partitions 21 in two adjacent air outlets 2 are staggered.

[0106] In this embodiment, in two adjacent air outlets 2, the partition 21 in one air outlet 2 corresponds to the position of the sub-air outlet 22 in the other air outlet 2.

[0107] It is understandable that, in the first direction X1, the partition 21 inside one air outlet 2 is adjacent to the sub-air outlet 22 of another air outlet 2.

[0108] As the airflow is blown out from the air outlet 2, when it encounters the separator 21, the airflow velocity is close to 0. If the separator 21 is set in the corresponding position in two adjacent air outlets 2, the airflow at the separator 21 is interrupted in the first direction X1, and eddies are easily generated. The airflow is uneven, which can easily cause the hair to become tangled and affect the straightening effect.

[0109] In this embodiment, by staggering the partitions 21 within adjacent air outlets 2, dead zones in the airflow can be reduced, ensuring continuous airflow in the first direction X1 and preventing eddies. This results in a more uniform airflow from the air outlets 2, preventing hair from tangling and achieving a better straightening effect. Simultaneously, a more uniform airflow also better prevents hair from detaching from the receiving cavity 13.

[0110] In one embodiment of this utility model, in two adjacent air outlets 2, the position of the partition 21 in one air outlet 2 is arranged in the middle of the corresponding sub-air outlet 22 in the other air outlet 2.

[0111] In this embodiment, the number of air outlets 2 is even. The number of air outlets 2 is set to an even number, and the partitions 21 within adjacent air outlets 2 are staggered. Each sub-air outlet 22 has a corresponding partition 21. Along the first direction, the airflow is more uniform, preventing excessive airflow in areas where some sub-air outlets 22 are located. This makes the airflow on the air outlet surface more uniform, preventing airflow from concentrating in one area, thus preventing hair from tangling and also reducing noise.

[0112] In one embodiment, the air outlet 2 is elongated, and its length is 60-80 mm. Preferably, the length of the air outlet 2 is 65 mm.

[0113] The length of the air outlet 2 is set within 60-80mm, which is conducive to the even distribution of airflow on the air outlet 2, and the airflow intensity is also better, resulting in better direct output.

[0114] If the air outlet 2 is too long, the lengths of the first housing part 11 and the second housing part 12 need to be extended, which is inconvenient for the user. If the air outlet 2 is too short, only a small amount of hair can be blown at a time, which is also inconvenient for the user.

[0115] In summary, the length of air outlet 2 is set within 60-80mm, which not only conforms to ergonomic design and is convenient for users, but also achieves better airflow distribution and a better straightening effect.

[0116] Furthermore, in one embodiment of this utility model, the distance between two adjacent partitions 21 within each air outlet 2 is less than 5.5 mm. Preferably, the distance between two adjacent partitions 21 is 5 mm.

[0117] When the distance between two adjacent separators 21 is greater than 5.5mm, the airflow blown out of a single sub-outlet 22 is greater, which affects the overall uniformity of the airflow blown out from the outlet 2 and is not conducive to solving the problem of hair tangles.

[0118] When the distance between two adjacent separators 21 of the air outlet 2 is less than 5.5mm, the airflow blown from the air outlet 2 is more uniform and the hair will not be tangled.

[0119] In one embodiment, the width of the separator 21 along the extension direction X2 of the air outlet 2 is 1mm to 1.2mm.

[0120] In this embodiment, the separator 21 is integrally formed with the first housing portion 11 and / or the second housing portion 12. When the width of the separator 21 is less than 1 mm, the separator 21 is too small and not convenient for demolding. When the width of the separator 21 is greater than 1.2 mm, the area of ​​the separator 21 is too large, which causes more obstruction to the airflow of the air outlet 2. When the airflow flows out from the airflow chamber 14, the airflow will slow down when it hits the separator 21, which may generate vortices and affect the uniformity of airflow and the direct output effect.

[0121] Furthermore, in one embodiment of the present invention, the receiving cavity 13 has an open front end 131 and a rear end 132 opposite to the front end 131.

[0122] The rear end 132 is close to the air inlet 3, while the front end 131 is away from the air inlet 3. When using this nozzle accessory, the user can place hair into the receiving cavity 13 from the front end 131.

[0123] The separator 21 is inclined toward the rear end 132. Thus, the separator 21 can guide the airflow from the sub-outlet 22 toward the rear end 132 of the receiving cavity 13. This prevents hair from being blown forward by the outlet 2 during use, causing it to come out from the front end 131 of the receiving cavity 13 and affecting user experience.

[0124] Furthermore, in one embodiment of this utility model, airflow chambers 14 are provided in both the first housing portion 11 and the second housing portion 12. Air outlets 2 are provided in both the first wall 111 and the second wall 121. In a cross-section made with the first plane, the cross-sectional area of ​​the airflow chamber 14 is larger than the area of ​​the air inlet 3.

[0125] Specifically, the first plane is parallel to the first direction X1. Furthermore, the first plane is perpendicular to the second direction X2.

[0126] Since the first housing portion 11 and the second housing portion 12 are spaced apart, the airflow chamber 14 also comprises two parts. In a cross-section made with the first plane, the cross-sectional area of ​​the airflow chamber 14 includes the sum of the cross-sectional area of ​​the airflow chamber 14 in the first housing portion 11 and the cross-sectional area of ​​the airflow chamber 14 in the second housing portion 12.

[0127] During use, after the airflow enters from the air inlet 3, it enters the airflow chamber 14, which has a larger total area. This reduces the airflow velocity inside the airflow chamber 14, preventing the airflow from being too high and affecting the user experience. At the same time, it makes the airflow velocity from the air outlet 2 more suitable for styling hair.

[0128] The ratio of the cross-sectional area of ​​the airflow chamber 14 to the area of ​​the air inlet 3 can be 1.2 to 1.3. In this way, the airflow velocity can be maintained within an optimal range.

[0129] In one embodiment, the nozzle accessory further includes a connecting housing portion 15 that connects the first housing portion 11 and the second housing portion 12. The connecting housing portion 15 is provided with a connecting cavity 16 that connects the air inlet 3 and the airflow chamber 14, and the connecting cavity 16 gradually expands from one end of the air inlet 3 toward the airflow chamber 14.

[0130] After entering through the air inlet 3, the airflow passes through the connecting cavity 16 and enters the two airflow chambers. Since the connecting cavity 16 gradually expands from the air inlet 3 toward the airflow chamber 14, the airflow velocity gradually decreases as it passes through the connecting cavity 16, thereby reducing noise and improving the user experience.

[0131] Furthermore, in one embodiment of this application, the air inlet 3 is circular or elliptical. When the air inlet 3 is elliptical, the major axis of the ellipse is parallel to the first direction X1, and the minor axis is perpendicular to the first direction X1.

[0132] In one embodiment, the cross-section of the airflow chamber 14, when viewed in a cross-section made with a first plane, comprises two symmetrical semi-ellipses, the major axes of which are parallel to the first direction X1.

[0133] Preferably, two symmetrical semi-ellipses can be joined together to form a complete ellipse.

[0134] This optimizes the airflow path, ensuring a uniform distribution of airflow within the chamber and preventing hair damage caused by excessively high local wind speeds. Furthermore, the elliptical cross-section of the airflow chamber 14, compared to other shapes, effectively reduces airflow turbulence within the chamber, further lowering noise levels and enhancing the user experience. The elliptical design, with its major axis parallel to the first direction X1, also helps guide airflow out more smoothly, resulting in a more natural and smooth styling effect.

[0135] Further, see Figure 6 In one embodiment of this utility model, a first air distribution member 7 is further provided in the airflow chamber 14. The first air distribution member 7 extends in the component of the first direction X1.

[0136] The first air distribution component 7 extends along the first direction X1, which can be understood as the first air distribution component 7 extending along the first direction X1, or the extension direction of the first air distribution component 7 forming an acute angle with the first direction X1.

[0137] In a specific embodiment, both the first air distributor 7 and the second air distributor 8 are inclined, specifically, both the first air distributor 7 and the second air distributor 8 are inclined toward the rear end 132. Specifically, the side of the first air distributor 7 and the second air distributor 8 closer to the second end 134 is inclined toward the rear end 132 relative to the side closer to the first end 133, thereby further guiding the air flowing out from the air outlet 2 to the rear end 132 of the receiving cavity 13, preventing hair from drifting out from the opening at the front end 131 of the receiving cavity 13.

[0138] Along the extension direction of the air outlet 2, the distance between the first air distribution component 7 and the front end of the air outlet 2 is less than half the length of the air outlet 2.

[0139] In this embodiment, a front region of the air outlet area is formed between the first air distributor 7 and the front end of the air outlet 2. By setting the first air distributor 7, the airflow in the airflow chamber 14 can be further blocked, thereby further reducing the airflow in the front region and minimizing the airflow in the front region, thus preventing hair from blowing out from the front end 131 of the receiving cavity 13.

[0140] Furthermore, in one embodiment of this utility model, a second air distribution member 8 is also provided in the airflow chamber 14, and the second air distribution member 8 extends at least along the component of the first direction X1. The second air distribution member 8 and the first air distribution member 7 are spaced apart along the extension direction of the air outlet 2. The first air distribution member 7 is closer to the front end 131 than the second air distribution member 8.

[0141] The extension direction of the second air distribution component 8 can be the same as or different from that of the first air distribution component 7. By setting the second air distribution component 8, the airflow flowing into the front area can be further blocked, reducing the air volume of the front area.

[0142] In one embodiment, the length of the first air distributor 7 is greater than the length of the second air distributor 8. A central region of the air outlet area is formed between the first air distributor 7 and the second air distributor 8. A rear region of the air outlet area is formed between the second air distributor 8 and the rear end 132 of the air outlet 2.

[0143] In this embodiment, the length of the first air distribution member 7 is measured along the extending direction of the first air distribution member 7. The length of the second air distribution member 8 is measured along the length direction of the second air distribution member 8.

[0144] The length of the second air distribution component 8 is less than that of the first air distribution component 7, so that the airflow is concentrated in the middle area between the first air distribution component 7 and the second air distribution component 8 as it flows from the air inlet 3 toward the front end 131. This maximizes the airflow in the middle area, which has a significant effect on quickly drying hair and improving blow-drying efficiency.

[0145] When using this accessory, the hair is concentrated in the middle area, resulting in a better straightening effect. At the same time, due to the setting of the second air distribution component 8, the air volume in the rear area is reduced, avoiding the problem of excessive hair blowing due to excessive air volume in the rear area.

[0146] Furthermore, in one embodiment of this utility model, a first air distributor 7 and a second air distributor 8 are provided inside both airflow chambers 14. The inner surface of the first wall 111 is provided with the first air distributor 7 and the second air distributor 8 protruding towards the interior of the airflow chamber 14, and the inner surface of the second wall 121 is also provided with the first air distributor 7 and the second air distributor 8 protruding towards the interior of the airflow chamber 14. The protruding thickness of the first air distributor 7 is greater than the protruding thickness of the second air distributor 8.

[0147] Thus, the first air distributor 7 has a larger protrusion thickness, which can effectively concentrate the airflow to the central area. At the same time, the second air distributor 8 has a smaller protrusion thickness, so it will not obstruct the airflow too much. This allows the airflow to flow smoothly through the second air distributor 8, further reducing the airflow speed in the rear area. This design not only improves the drying efficiency but also avoids the problem of excessive hair blowing due to excessive airflow in the rear area, resulting in a better user experience.
