Detailed Implementation

[0024] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0025] Combination Figures 1-11 As shown, the hair care device 100 according to a first aspect embodiment of the present invention includes a first arm 10, a second arm 20, and a first hair clip 30. The first arm 10 and the second arm 20 cooperate with each other and are allowed to open and close relative to each other under the force of the hand to clamp and process hair (for example, when the first arm 10 and the second arm 20 clamp hair and move it from the root to the tip, the clamping force of the two arms, combined with high temperature, can stretch and straighten curly and frizzy hair strands). The first hair clip 30 can guide the hair more smoothly into the heated position between the two arms, and the cooperation of the two arms can also help the user more easily and evenly clamp a strand of hair, ensuring that the hair can more evenly contact the heating on the two arms. The heated area provides a better straightening effect and user experience (for example, when combing finer, softer hair, such as bangs, sideburns, or dealing with stray hairs at the ends, the first hair clip 30 on the arm can gently clamp the target hair strands to prevent them from slipping between the two arms during the heated combing process, ensuring that each strand of hair can fully contact the heated surface and be stretched evenly. Also, for naturally curly, frizzy roots or mid-lengths, the clamping force of the first hair clip 30 can enhance the forced stretching effect on the hair strands. Combined with the high temperature setting of the heated area, it makes the curly parts easier to straighten and reduces the number of times you need to comb).

[0026] Specifically, the second arm 20 is disposed opposite to the first arm 10, and a channel for receiving hair is formed between them. The second arm 20 is movable relative to the first arm 10 so that the first arm 10 and the second arm 20 can selectively open and close under the action of external force. The first hair clip 30 is disposed on the first arm 10 to clamp hair when the first arm 10 and the second arm 20 are closed. The first hair clip 30 includes an elastic deformation portion 31, at least a portion of which protrudes from the side of the first arm 10 facing the second arm 20. A cavity 311 is provided in the elastic deformation portion 31 to generate elastic deformation when clamping hair.

[0027] Specifically, the first arm 10 and the second arm 20 are arranged opposite to each other and can rotate relative to each other. This allows the first arm 10 and the second arm 20 to selectively open and close under external force, which is beneficial for the user to perform the opening and closing actions between the first arm 10 and the second arm 20 according to styling needs. When the first arm 10 and the second arm 20 are open relative to each other, it is easier for the user to place the hair between the first arm 10 and the second arm 20. When the first arm 10 and the second arm 20 are closed relative to each other, the first arm 10 and the second arm 20 can clamp the hair, which is convenient for straightening the hair. It also makes it easier for the user to store the hair straightening tool after the straightening work is completed, reducing the space occupied by the care tool 100 and improving its practicality and flexibility of use.

[0028] In detail, a channel for receiving hair is formed between the first arm 10 and the second arm 20. That is, when the user uses the care device 100, the hair strand is captured in the channel, and when the hair is pulled away from the care device 100 during use, the hair gradually leaves the channel.

[0029] Furthermore, the first hair clip 30 is disposed on the first arm 10, and at least a portion of the elastic deformation portion 31 on the first hair clip 30 protrudes from the side of the first arm 10 facing the second arm 20. This facilitates the contact between the elastic deformation portion 31 and the hair. Since the elastic deformation portion 31 can undergo elastic deformation under external force, it is convenient for the elastic deformation portion 31 to adjust the clamping force on the hair according to different hair types through its own deformation, reducing hair breakage caused by excessive pulling or friction, thereby achieving an adaptive hair clamping effect, protecting the user's hair, and improving the user's comfort experience. For example, when the hair is thick or there is a lot of hair, the hair clip will open slightly to reduce the hard pressure on the hair; when dealing with fine hair or close to the scalp, it can naturally contract to provide moderate pressure, ensuring clamping stability while avoiding hair breakage or scalp pain due to excessive force.

[0030] Furthermore, since the elastic deformation part 31 can adaptively adjust the clamping force through deformation, it can adapt to different hair types and scenarios, whether it is fine and soft hair (which needs to be clamped lightly to prevent slippage), coarse and hard hair (which needs to be fixed with slightly stronger force) or damaged hair (which needs to be fixed with gentle force to prevent breakage). Moreover, there is no need to manually adjust the clamping force frequently during the clamping process, thereby reducing the operation threshold. The elastic deformation capability of the elastic deformation part 31 can also deform slightly with the shape of the hair, ensuring that the clamping surface fits the hair more closely, reducing the problem of local missed clamping or uneven force, and making the heating and setting more uniform.

[0031] Optionally, the elastic deformation part 31 can be made of plastic. Plastic materials are usually made of soft, high-temperature resistant materials such as silicone, which can insulate against the high temperature during the heating process to a certain extent, reducing the risk of burns when the user accidentally touches it. Moreover, plastic materials are relatively gentle and cause less damage to the hair, which helps to reduce hair breakage caused by excessive pulling or friction. The clamping force of plastic materials can be adjusted according to different hair types, making them more friendly to fine or fragile hair and avoiding unnecessary damage.

[0032] Furthermore, the elastic deformation section 31 is provided with a cavity 311, which makes the elastic deformation section 31 more elastic, allowing it to deform more easily and evenly under pressure, thus better conforming to the hair and improving the adaptive clamping force of the hair care device 100, thereby enhancing the user experience. In addition, the cavity 311 helps reduce the amount of material used in the elastic deformation section 31, thereby reducing manufacturing costs.

[0033] Therefore, by setting up this hair care device 100, it can adaptively adjust the clamping force according to different hair types and amounts during the hair clamping process, avoiding the problem of hair slipping due to insufficient force or hair breaking due to excessive force, thus ensuring the clamping stability of different types of hair during the clamping process. Moreover, the operation process does not require the user to frequently adjust the clamping force manually, reducing the difficulty of operation.

[0034] According to some optional embodiments of the present invention, combined with Figures 1-5 , Figure 7 , Figure 8 and Figure 10 As shown, the first hairpin 30 extends along the length direction of the first arm 10, and the cavity 311 extends along the length direction of the first hairpin 30.

[0035] The above arrangement can effectively increase the clamping range of the first hair clip 30, allowing for a larger contact area between the first hair clip 30 and the hair, thus enabling it to clamp more hair at the same time and improving the efficiency of straight hair styling. The cavity 311 inside the elastic deformation part 31 extends along the length direction of the first hair clip 30. Since the extension direction of the cavity 311 is consistent with the length direction of the first hair clip 30, the elastic deformation part 31 can deform more evenly along its own length direction during the process of the first hair clip 30 clamping the hair, avoiding localized deformation concentration, thereby improving the uniformity of deformation of the first hair clip 30 during the hair clamping process.

[0036] Alternatively, combined Figures 1-5 , Figure 7 , Figure 8 and Figure 10 As shown, at least one end of the cavity 311 along its length is provided with a first opening 312 communicating with the cavity 311. With this configuration, when the elastic deformation part 31 is compressed, the cavity 311 is compressed and deformed, and the volume of the cavity 311 decreases. The air in the cavity 311 can be discharged outward through the first opening 312. This avoids the risk of pressure accumulation due to the inability of air to escape from the cavity 311, thereby avoiding the formation of an air cushion effect (the air is compressed and generates reverse pressure, which makes the cavity 311 difficult to compress and may cause bouncing due to excessive pressure release when it rebounds). This ensures the compressibility and resilience of the elastic deformation part 31.

[0037] Alternatively, a second opening communicating with the cavity 311 is provided on the side of the cavity 311 near the first arm 10. With this arrangement, when the elastic deformation part 31 is compressed, the cavity 311 is compressed and deformed, and the volume of the cavity 311 is reduced accordingly. The air in the cavity 311 can be discharged outward through the second opening. This can avoid the risk of pressure accumulation due to the inability of air to escape from the cavity 311, thereby avoiding the formation of an air cushion effect and ensuring the compressibility and resilience of the elastic deformation part 31.

[0038] According to some optional embodiments of the present invention, combined with Figure 10 As shown, the outer surface of the elastic deformation part 31 is constructed with an arc surface. When the elastic deformation part 31 is compressed, the arc surface can make the force more evenly distributed, avoid local stress concentration, and thus improve the service life of the elastic deformation part 31.

[0039] Specifically, in combination Figure 10As shown, the outer surface of the elastic deformation portion 31 includes a first convex arc surface 313, a first concave arc surface 314, and a second concave arc surface 315. The first convex arc surface 313 protrudes towards the second arm 20. The first concave arc surface is connected to one end of the first convex arc surface 313 near the first arm 10, and the first concave arc surface 314 is recessed towards the elastic deformation portion 31. The second concave arc surface 315 is connected to the other end of the first convex arc surface 313 near the first arm 10, and the second concave arc surface 315 is recessed towards the elastic deformation portion 31. The second concave arc surface 315 is disposed opposite to the first concave arc surface 314.

[0040] Understandably, during the hair clamping process, the first convex arc surface 313 makes pre-contact with the hair strands. The first convex arc surface 313 can reduce the direct hard contact between the first hair clip 30 and the scalp and hair strands. In other words, the first convex arc surface 313 will make buffered contact with the edge of the scalp or the root of the hair strands, avoiding scalp pain caused by pressure or scratching from sharp edges, or hair strands being pulled and broken by sharp edges, thereby reducing physical damage to the scalp and hair strands. It can also guide the hair strands to naturally conform (because the curvature of the first convex arc surface 313 is more compatible with the natural curvature of the hair), thereby improving the smoothness of hair sliding, reducing jamming or tangling, and improving the straightening effect.

[0041] Furthermore, the two sides of the first convex arc surface 313 are respectively connected to the first concave arc surface 314 and the second concave arc surface 315. The first concave arc surface 314 and the second concave arc surface 315 are located at the end of the elastic deformation part 31 near the first arm 10. Since the two arc surfaces are concave inward, the first concave arc surface 314 and the second concave arc surface 315 can provide compression deformation space. This is beneficial for the elastic deformation part 31 to compress and deform towards the end near the first arm 10, thereby ensuring the compressibility of the elastic deformation part 31 and avoiding bulging. Moreover, it can also make the compressive force on the first convex arc surface 313 evenly distributed to the first concave arc surface 314 and the second concave arc surface 315, avoiding stress concentration at the connection between the first convex arc surface 313 and the first concave arc surface 314 and the second concave arc surface 315, thereby ensuring the uniformity of the force on the elastic deformation part 31.

[0042] According to some optional embodiments of the present invention, combined with Figure 10 As shown, at least part of the inner wall of cavity 311 is constructed in an arc shape.

[0043] Specifically, the arc-shaped inner wall can distribute the stress on the inner wall more evenly, avoid local stress concentration, and thus improve the uniformity of force distribution; it can also provide flexible support for the hair being clamped, achieving a gradual compression effect, thereby improving the user's comfort during the hair clamping process.

[0044] According to some optional embodiments of the present invention, combined with Figure 10As shown, along the thickness direction of the first arm 10, the width of the cavity 311 first increases and then decreases in the direction extending from the first arm 10 to the second arm 20.

[0045] In other words, the width of cavity 311 is smaller at the end away from the second arm 20, and the cavity 311 in this area has higher stiffness, which can provide a stronger support effect. The width of cavity 311 gradually increases in the direction extending from the first arm 10 to the second arm 20. At this time, the cavity 311 is larger, which makes the cavity 311 in this area more likely to undergo compression deformation, thereby improving compression resilience. The width of cavity 311 gradually decreases again at the end closer to the second arm 20. The cavity 311 in this area can gradually disperse stress to the cavity 311 connected to this area through a gradually expanding geometric structure, thus forming a progressive compression response effect. The cavity 311 is soft during initial compression and gradually hardens later, thereby improving the comfort and protection of the first hair clip 30 when clamping hair.

[0046] According to some optional embodiments of the present invention, combined with Figure 8 and Figure 10 As shown, the first hair clip 30 also includes a fixing part 32, which extends along the length of the first arm 10 and is connected to the side of the elastic deformation part 31 away from the second arm 20; wherein, the first arm 10 is provided with a mounting groove 11, and the fixing part 32 is provided in the mounting groove 11.

[0047] The fixing part 32 is used to establish a firm connection with the first arm 10. Since the fixing part 32 extends along the length of the first arm 10, the contact area between the fixing part 32 and the mounting groove 11 can be effectively increased, thereby improving the connection strength and reliability, and ensuring the positional stability of the elastic deformation part 31. The fixing part 32 is connected to the side of the elastic deformation part 31 away from the second arm 20, which can shorten the distance between the fixing part 32 and the first arm 10, which is conducive to the mutual connection and fixation of the fixing part 32 and the first arm 10, thereby improving the rationality of the arrangement.

[0048] Specifically, in combination Figure 8 and Figure 10 As shown, at least one end of the fixing part 32 along its own length direction is provided with a stepped part 321, and the stepped part 321 is engaged with the mounting groove 11.

[0049] Understandably, the stepped portion 321 can increase the contact area between the fixing portion 32 and the mounting groove 11, thereby improving the connection strength between the fixing portion 32 and the mounting groove 11. Moreover, the outer cross section of the stepped portion 321 can form a stop and limit relationship with the inner wall of the mounting groove 11 in multiple directions (such as the length direction, width direction and thickness direction of the first hair clip 30), avoiding the risk of the first hair clip 30 shifting and shaking during use, thereby ensuring the working stability of the first hair clip 30.

[0050] According to some optional embodiments of the present invention, combined with Figure 5 , Figure 7 and Figure 8 As shown, the first arm 10 is provided with a first air outlet 12, and the first hairpin 30 and the first air outlet 12 are spaced apart in the width direction of the first arm 10. The first air outlet 12 blows air in the width direction of the first arm 10. For example, the first air outlet 12 can blow out hot air.

[0051] Specifically, when a user is straightening their hair, the first arm 10 and the second arm 20 hold the hair strands and move them along the direction from the roots to the ends. Since the air outlet 12 has the same air outlet direction as the width direction of the first arm 10 (the width direction of the first arm 10 is the same as the direction of hair straightening), the air blown out by the first air outlet 12 can straighten the hair to the greatest extent in the direction of straightening, thereby improving the straightening effect. Moreover, it can avoid the wind direction and the hair straightening direction from interfering with each other, reduce the ineffective loss of air volume and wind speed, and thus improve the straightening efficiency.

[0052] According to some optional embodiments of the present invention, combined with Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the first arm 10 includes a first housing 13 and a first clamping plate 14. The first housing 13 is open on the side facing the second arm 20. The first clamping plate 14 is disposed on the side of the first housing 13 facing the second arm 20. The first clamping plate 14 and the first housing 13 together form a first air chamber 15. The first air chamber 15 is connected to the first air outlet 12. The first hairpin 30 is disposed on the first clamping plate 14 and is located on the leeward side of the first air outlet 12.

[0053] The first housing 13 protects the internal structure. The first housing 13 is open on the side facing the second arm 20, so that it can provide a mounting position for the first clamp 14 without interfering with the contact of the hair on the side of the first clamp 14 away from the first housing 13. The first clamp 14 and the first housing 13 together form a first air chamber 15 to contain air. The first air chamber 15 is connected to the first air outlet 12. The air in the first air chamber 15 can be discharged through the first air outlet 12, which facilitates the directional guidance of the hair in the clamped state of the two arms, thereby improving the straightening effect.

[0054] In addition, the first clamping plate 14 can provide a stable support for the first hair clip 30, avoiding the risk of the first hair clip 30 loosening and falling off during use; and the first hair clip 30 is located on the leeward side of the first air outlet 12, which can prevent the first hair clip 30 from blocking the wind at the first air outlet 12, thereby ensuring the smoothness of the wind blowing out of the first air outlet 12, and also prevent the first hair clip 30 from being impacted by the wind blowing out of the first air outlet 12 during clamping, thereby avoiding the problem of the first hair clip 30 shifting or the clamping force decreasing due to wind force.

[0055] Specifically, in combination Figure 7 As shown, the first clamp 14 includes a main plate segment 141 and an air guide segment 142. The main plate segment 141 is constructed in a straight plate shape. The air guide segment 142 is connected to the main plate segment 141 and together forms a first air outlet 12. The elastic deformation part 31 is located on one side of the air guide segment 142 in the width direction of the first arm 10. At least part of the air guide segment 142 is bent toward the side away from the first hairpin 30.

[0056] Understandably, the straight plate has a large surface area to volume ratio (i.e., a large ratio of surface area to volume). The main plate segment 141 is constructed in a straight plate shape. This can effectively increase the extension size of the main plate segment 141 without increasing its weight too much, thereby reducing material consumption and improving economy. At least part of the air guide segment 142 is bent towards the side away from the first hairpin 30. This can change the extension direction of the main plate segment 141 and smoothly guide the airflow, improving the smoothness of the airflow.

[0057] Furthermore, combined Figure 7 , Figure 8 and Figure 10 As shown, along the width direction of the first arm 10, the elastic deformation portion 31 extends obliquely toward the side near the air guide section 142. A mating surface 316 is provided on the side of the elastic deformation portion 31 near the air guide section 142, and the mating surface 316 is adapted to at least a portion of the outer periphery of the air guide section 142.

[0058] In other words, the mating surface 316 can effectively increase the contact area between the elastic deformation part 31 and the air guide section 142, thereby improving the connection reliability between the two. Moreover, the mating surface 316 and at least part of the outer periphery of the air guide section 142 are mutually adapted in shape, so a customized fixing effect can be achieved through precise shape matching. The mating surface 316 and at least part of the outer periphery of the air guide section 142 can form a physical interlock, thereby limiting the displacement of the elastic deformation part 31 and avoiding the risk of slippage and shaking of the elastic deformation part 31 during the clamping process, thereby ensuring the clamping stability of the elastic deformation part 31.

[0059] Specifically, in combination Figure 7 and Figure 8 As shown, the first arm 10 is also provided with a second air outlet 16. The first air outlet 12, the first hairpin 30, and the second air outlet 16 are arranged sequentially at intervals along the width direction of the first arm 10. For example, the second air outlet 16 can blow out room temperature air.

[0060] As arranged as described above, the gap between the first air outlet 12, the first hairpin 30, and the second air outlet 16 prevents the first hairpin 30 from blocking the two air outlets, thus ensuring the smooth airflow of the two air outlets. It also allows the first hairpin 30 to be in a relatively stable space between the two airflow areas, reducing the risk of loosening caused by the airflow from the air outlets on both sides impacting the first hairpin 30, and enhancing the positional stability of the first hairpin 30 during use.

[0061] Furthermore, combined Figure 7 and Figure 8 As shown, the air outlet direction of the first air outlet 12 and the air outlet direction of the second air outlet 16 are perpendicular to each other.

[0062] The first air outlet 12 is in the same direction as the hair straightening, and the air blown out from the first air outlet 12 can quickly straighten the hair along the straightening direction. The second air outlet 16 is perpendicular to the straightening direction of the hair, and can cool down the hair after it has been straightened by the hot air from the first air outlet 12 and the first hair clip 30, thereby achieving a quick straightening and styling effect.

[0063] Furthermore, the extension length of the first hairpin 30 is not less than the length of the first air outlet 12 and the second air outlet 16. Since the first hairpin 30 is located between the first air outlet 12 and the second air outlet 16, it is equivalent to dividing the channel between the two arms into one part (the cavity where the second air outlet is located) and another part (the cavity where the first air outlet is located), thus avoiding mutual interference of fluids between the upper and lower cavities.

[0064] Specifically, in combination Figure 7 and Figure 8As shown, the first arm 10 is provided with a second air chamber 17 that communicates with the second air outlet 16. The second air chamber 17 and the first air chamber 15 are spaced apart from each other, and the second air chamber 17 communicates with the second air outlet 16. The volume of the second air chamber 17 is smaller than the volume of the first air chamber 15.

[0065] The first air chamber 15 is connected to the first air outlet 12, and the second air chamber 17 is connected to the second air outlet 16. The first air chamber 15 and the second air chamber 17 are set independently and spaced apart from each other, which can avoid mutual interference and crosstalk between the air in the two air chambers, thereby ensuring the airflow stability in the two air chambers.

[0066] In addition, since the air blown out by the first air outlet 12 is mainly used to straighten the hair in the direction of straightening, the volume of the first air chamber 15 is larger than that of the second air chamber 17. This allows the first air chamber 15 to hold more air, thereby increasing the air volume of the first air outlet 12 and improving the straightening efficiency. The volume of the second air chamber 17 is smaller than that of the first air chamber 15. The smaller volume of the second air chamber 17 can quickly empty or fill with airflow, thereby improving the air outlet response speed of the second air outlet 16 and quickly cooling the heated hair.

[0067] Furthermore, combined Figure 3 , Figure 7 , Figure 8 and Figure 11 As shown, the first arm 10 is provided with a second air chamber 17 that communicates with the second air outlet 16, and the second arm 20 is provided with a third air outlet 21 and a third air chamber 22 that communicates with the third air outlet 21. The second air outlet 16 and the third air outlet 21 are arranged opposite to each other.

[0068] In other words, the air in the second air chamber 17 can be discharged through the second air outlet 16, and the air in the third air chamber 22 can be discharged through the third air outlet 21. The second air outlet 16 and the third air outlet 21 are arranged opposite to each other. Since the hair being clamped is blown on both sides, this can improve the cooling and styling effect of the hair. The second air outlet 16 and the third air outlet 21 are arranged opposite to each other, so that the hair being clamped can form a counter-current airflow effect in the thickness direction of the first arm 10, avoiding the formation of blind spots, thereby improving the cooling efficiency. Moreover, the second air outlet 16 and the third air outlet 21 are more regular in spatial layout, which can simplify the processing technology and improve manufacturing efficiency.

[0069] Furthermore, combining Figure 3 and Figure 11 As shown, the nursing device 100 also includes a temperature and humidity sensor 50, which is disposed in one of the second air chamber 17 and the third air chamber 22 to sense the temperature and humidity values ​​of the air flowing from the other of the second air chamber 17 and the third air chamber 22 to itself.

[0070] For example, the temperature and humidity sensor 50 is located in the third air chamber 22 in the second arm 20. The third air chamber 22 can provide structural protection for the temperature and humidity sensor 50, preventing the risk of damage to the temperature and humidity sensor 50 by external objects. The air blown out from the second air outlet 16, which is connected to the second air chamber 17, flows through the hair between the two arms and then through the third air outlet 21 into the third air chamber 22. The temperature and humidity sensor 50 in the third air chamber 22 can promptly sense and detect the actual temperature and humidity changes of the air after it passes through the hair. This is beneficial for more accurately adjusting the air volume, air speed, or temperature parameters of the air in the first air chamber 15 and the second air chamber 17 based on the detection data, thereby improving the intelligence of the care device 100.

[0071] Furthermore, the temperature and humidity sensor 50 is connected to the controller of the hair care device 100 via an electrical signal. The detection data from the temperature and humidity sensor 50 can be directly transmitted to the controller of the hair care device 100. The controller controls the opening of the motor and / or heating wire of the hair care device 100 based on the temperature and humidity of the hair, thereby applying more reasonable airflow characteristics (parameters such as flow rate and temperature) to the hair, ensuring the drying rate while avoiding overheating damage. For example, when the temperature and humidity sensor 50 detects that the hair moisture content is too high (such as after washing), the controller can control the relevant structure to automatically reduce the heating temperature or adjust the heating power to avoid high temperature causing denaturation of hair protein and rapid moisture loss. If the environment is dry (such as in autumn and winter), the controller can control the relevant structure to reduce the duration of high temperature, reducing the risk of static electricity and breakage of the hair, thereby achieving personalized protection based on hair type and environment, and thus taking into account both styling and hair care effects.

[0072] Specifically, in combination Figures 6-9 As shown, the nursing device 100 also includes a first heating element 60. The first arm 10 is provided with a first air chamber 15 that communicates with the first air outlet 12. The first heating element 60 is disposed in the first air chamber 15 and is used to heat the air in the first air chamber 15.

[0073] In other words, the first heating element 60 in the first air chamber 15 can rapidly heat the air in the first air chamber 15, raising the temperature of the air in the first air chamber 15, which helps to improve the drying efficiency of the hair and thus increases the speed of hair styling.

[0074] Furthermore, the first heating element 60 includes a heating frame 61 and a heating wire. The heating frame 61 is disposed in the first air chamber 15 and its length direction forms an acute angle with the length direction of the first arm 10. The heating wire is wound around the outer periphery of the heating frame 61.

[0075] It is understandable that the length direction of the heating frame 61 forms an acute angle with the length direction of the first arm 10, and heating wires are wound around the outer periphery of the heating frame 61. In this way, the effective layout path of the heating frame 61 and heating wires can be extended within the limited space of the first air chamber 15, increasing the contact area between the heating frame 61, heating wires and air, reducing local heat concentration and heating blind spots, thereby effectively improving the heating efficiency and temperature uniformity of the air in the first air chamber 15.

[0076] Specifically, in combination Figure 5 and Figure 9 As shown, the bottom of the first air chamber 15 is provided with a first air inlet 151, the heating frame 61 includes a first section and a second section, the heating wire is only wound around the outer periphery of the first section, the second section is connected to the end of the first section away from the first air inlet 151, and the length of the second section is less than that of the first section.

[0077] In other words, the airflow enters the first air chamber 15 from the first air inlet 151 and passes through the first section and the second section of the heating frame 61 in sequence. Since the first section is close to the first air inlet 151, after the airflow enters from the first air inlet 151, it first flows through the longer first section and comes into full contact with the heating wire wrapped on the first section. The two complete the main heating process through heat exchange, ensuring that the airflow in the first air chamber 15 obtains the basic target temperature. The second section, which is connected to the end of the first section, is short and the heating wire is not wrapped around the outer periphery of the second section. The space near the second section can play a buffering and transitioning role for the airflow, avoiding overheating of the airflow in the area far from the first air inlet 151 due to continuous contact with the heating wire, reducing the risk of heat accumulation, and thus making the temperature of the heated airflow more uniform and stable.

[0078] In addition, the design of not wrapping the heating wire in the second section can save materials and energy, and reduce airflow resistance caused by structural redundancy (such as the heating wire forming a physical obstruction to the airflow), thereby improving the smoothness of airflow in the first air chamber 15.

[0079] Furthermore, combined Figure 2 , Figure 3 and Figure 11 As shown, the nursing device 100 also includes a second hair clip 40, which is disposed on the second arm 20 and is disposed opposite to the first hair clip 30. At least a portion of the second hair clip 40 protrudes from the side of the second arm 20 facing the first arm 10.

[0080] Understandably, the first hair clip 30 on the first arm 10 and the second hair clip 40 on the second arm 20 are positioned opposite each other. The first hair clip 30 and the second hair clip 40 can guide the hair to enter the heating position between the two arms more smoothly. Moreover, the two can help the user to clamp a bunch of hair more easily and evenly, ensuring that each hair contacts the heating area as much as possible, thereby achieving a better straightening effect and user experience.

[0081] Alternatively, the surfaces of the first hair clip 30 and the second hair clip 40 can be made of two different materials, such as at least one surface of the first hair clip 30 being made of plastic and at least one surface of the second hair clip 40 being made of metal. The first hair clip 30 prevents hair from slipping by increasing friction, while the second hair clip 40 ensures stable clamping force and uniform heating, so that the desired effect can be achieved every time. Moreover, the aforementioned materials can prevent the two hair clips from generating excessive friction when clamping hair, thereby avoiding the problem of users having to exert effort when styling their hair.

[0082] Specifically, the second hair clip 40 has the same structure as the first hair clip 30, which ensures that the two are consistent in terms of clamping force, fitting curvature, and operating feel. This avoids problems such as unstable clamping on one side or uneven force due to structural differences, thereby improving the balance of clamping effect and reducing hair pulling or loosening.

[0083] Furthermore, combined Figure 2 , Figure 3 and Figure 11 As shown, the second arm 20 includes a second housing 25 and a second clamping plate 26. The second housing 25 is open on the side facing the first arm 10, and the second clamping plate 26 is disposed on the side of the second housing 25 facing the first arm 10. The second hairpin 40 is integrally formed on the second clamping plate 26.

[0084] The second housing 25 can protect the internal structure. The second housing 25 is open on the side facing the first arm 10, so that it can provide a mounting position for the second clamp 26 without interfering with the contact of the second clamp 26 with the hair on the side away from the second housing 25.

[0085] Furthermore, the second hairpin 40 is integrally formed with the second clamping plate 26. Compared with separate assembly, this can reduce the number of parts and assembly time, thereby reducing assembly steps, reducing manufacturing costs, and improving production efficiency. It can also avoid the fitting errors that may occur in traditional multi-part assembly, thereby improving the precision and consistency of the product. It can also reduce stress concentration points (due to the absence of seams and welds), thereby improving the overall structural strength and rigidity of the second hairpin 40.

[0086] Specifically, in combination Figure 2 , Figure 3 and Figure 11 As shown, the second clamping plate 26 and the second housing 25 together form a third air chamber 22 and a fourth air chamber 24. The third air chamber 22 is connected to the third air outlet 21. A second hairpin 40 is provided on the second clamping plate 26 and the second hairpin 40 is located on the leeward side of the third air outlet 21. The second arm 20 is also provided with a fourth air outlet 23. The fourth air outlet 23 is connected to the fourth air chamber 24. The fourth air outlet 23 and the third air outlet 21 are spaced apart along the width direction of the second arm 20.

[0087] The air in the fourth air chamber 24 can be discharged through the fourth air outlet 23, which facilitates the directional guidance of the hair held between the arms, thereby improving the straightening effect.

[0088] In addition, the second clamp 26 can provide a stable support for the second hairpin 40, avoiding the risk of the second hairpin 40 loosening and falling off during use; and the second hairpin 40 is located on the leeward side of the fourth air outlet 23, which can prevent the second hairpin 40 from blocking the wind at the fourth air outlet 23, thereby ensuring the smoothness of the wind blowing out of the fourth air outlet 23, and also prevent the second hairpin 40 from being impacted by the wind blowing out of the fourth air outlet 23 during clamping, thereby avoiding the problem of the second hairpin 40 shifting or the clamping force decreasing due to wind force.

[0089] Furthermore, the nursing device 100 also includes a second heating element disposed in the fourth air chamber 24, which is used to heat the air in the fourth air chamber 24.

[0090] In other words, the second heating element in the fourth air chamber 24 can quickly heat the air in the fourth air chamber 24, raising the temperature of the air in the fourth air chamber 24, which helps to improve the drying efficiency of the hair and thus increase the speed of hair styling.
