[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 nursing device 100 according to a first aspect embodiment of the present invention includes a first arm 10, a second arm 20, and a temperature and humidity sensor 30. The first arm 10 and the second arm 20 can cooperate with each other and are allowed to open and close relative to each other under the force of a hand to clamp and process hair (for example, when the first arm 10 and the second arm 20 clamp the 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 temperature and humidity sensor 30 can be used to detect the temperature and humidity values ​​of the target area.

[0026] Specifically, the first arm 10 is provided with a first air chamber 12 with a first vent 11, the second arm 20 is disposed opposite to the first arm 10 and a channel 23 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 second arm 20 is provided with a second air chamber 22 with a second vent 21, the first vent 11 and the second vent 21 are disposed opposite to each other, and a temperature and humidity sensor 30 is disposed in the second air chamber 22 to sense the temperature and humidity values ​​of the wind flowing into itself from the first air chamber 12.

[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 hair straightening work is completed, reducing the space occupied by the care tool 100, thereby improving practicality and flexibility of use.

[0028] In detail, a channel 23 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 23, and when the hair is pulled away from the care device 100 during use, the hair gradually leaves the channel 23.

[0029] Furthermore, the first vent 11 on the first arm 10 and the second vent 21 on the second arm 20 are positioned opposite each other. This allows the air in the first air chamber 12 to directly enter the second air chamber 22 through the hair held in the first vent 11-channel 23-second vent 21 and be sensed in real time by the temperature and humidity sensor 30, thereby ensuring the authenticity and timeliness of the detection data of the hair during the styling process.

[0030] Furthermore, the temperature and humidity sensor 30 is located in the second air chamber 22 of the second arm 20. The second air chamber 22 can provide structural protection for the temperature and humidity sensor 30, reducing the risk of damage to the temperature and humidity sensor 30 by external objects. The air blown out from the first vent 11 connected to the first air chamber 12 passes through the hair clamped in the channel 23 and then flows into the second air chamber 22 through the second vent 21. The temperature and humidity sensor 30 in the second air chamber 22 can promptly sense and detect the actual temperature and humidity changes of the air after it passes through the hair in the channel 23. This allows the care device 100 to more accurately adjust the air volume, air speed, or temperature parameters in the first air chamber 12 based on the detection data, thereby improving the intelligence of the care device 100.

[0031] For example, when the temperature and humidity sensor 30 detects that the moisture content of the air is too high (such as after washing), the hair care device 100 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 loss of moisture. When the temperature and humidity sensor 30 detects that the moisture content of the air is too low (such as when the environment or hair is dry), the hair care device 100 can control the relevant structure to reduce the duration of high temperature, reduce the risk of static electricity and breakage of hair, thereby achieving the effect of personalized protection according to hair type and environment, and thus taking into account both styling and hair care effects.

[0032] Optionally, the first arm 10 and the second arm 20 in the above embodiments can be interchanged, that is, the temperature and humidity sensor 30 can be set in either of the two arms.

[0033] Therefore, by setting a temperature and humidity sensor 30, it can sense and detect the real temperature and humidity changes after the wind passes through the hair in a timely manner, which helps the care device 100 to more accurately adjust the air volume, wind speed or temperature parameters of the air in the first air chamber 12 according to the detection data, thereby improving the intelligence and care effect of the care device 100.

[0034] According to some optional embodiments of the present invention, combined with Figures 3-5 As shown, the second air chamber 22 extends along the length of the second arm 20, the second vent 21 extends along the length of the second air chamber 22, and the temperature and humidity sensor 30 is located in the second air chamber 22 on the side close to the second vent 21, and the temperature and humidity sensor 30 corresponds to the second vent 21.

[0035] The above arrangement helps to increase the ventilation range of the second vent 21, making it easier for the temperature and humidity sensor 30 to sense the air blowing from the first vent 11 to the second air chamber 22. Since the temperature and humidity sensor 30 corresponds to the second vent 21, it can maximize the sensing range of the air blowing from the first vent 11, thereby improving the accuracy and averaging of the detection data and avoiding the problem of local detection data deviation. Moreover, the temperature and humidity sensor 30 is located in the second air chamber 22 on the side close to the second vent 21, which can shorten the distance between the temperature and humidity sensor 30 and the hair in the channel 23. This avoids the problem of heat and moisture loss caused by the air blowing from the first air chamber 12 not flowing to the temperature and humidity sensor 30 in time after passing through the hair clamped in the channel 23, thus ensuring the authenticity and accuracy of the detection data of the temperature and humidity sensor 30.

[0036] Specifically, projecting along the thickness direction of the second arm 20, the projected length of the second vent 21 is L1, and the projected length of the temperature and humidity sensor 30 is L2. L1 and L2 satisfy the relationship: L2≥0.5×L1.

[0037] Understandably, the second vent 21 has a longer projected length in the thickness direction of the second arm 20. This effectively increases the ventilation capture range, allowing it to receive air from a longer area and avoiding data deviation caused by a small airflow area. In other words, it reduces the probability of inaccurate data due to uneven airflow at the first vent 11. Correspondingly, the temperature and humidity sensor 30 is also longer, expanding its sensing range for airflow from the second vent 21 into the second air chamber 22, thereby improving the authenticity, richness, and accuracy of the detection data. For example, the projected length L2 of the temperature and humidity sensor 30 can be 0.5×L1, 0.8×L1, or L1, etc., and is not limited to these.

[0038] Furthermore, combined Figures 3-5 As shown, the temperature and humidity sensor 30 includes a circuit board 31, a temperature sensing element, and a humidity sensing element. The circuit board 31 extends along the length of the second vent 21. The temperature sensing element is disposed on the side of the circuit board 31 near the second vent 21, and the humidity sensing element is disposed on the circuit board 31. The temperature sensing element is located on the side of the circuit board 31 near the second vent 21, and the temperature sensing elements are spaced apart.

[0039] Understandably, circuit board 31 can provide a unified mounting and circuit connection carrier for multiple temperature sensing elements and humidity sensing elements, eliminating the need to design a fixed structure and signal lines for each sensing element separately. This effectively simplifies the overall assembly process of temperature and humidity sensor 30, reduces the risk of failure caused by messy wiring, and facilitates the overall alignment of temperature and humidity sensor 30 with the second vent 21. Temperature sensing elements can be used to sense and detect the temperature value of the wind, and humidity sensing elements can be used to sense and detect the humidity value of the wind. The two are set apart from each other to avoid mutual interference, thereby ensuring the independence and stability of operation.

[0040] Alternatively, multiple temperature sensing elements are arranged at intervals along the length of the circuit board 31. This arrangement facilitates multi-point temperature sampling along the length of the circuit board 31 (by comparing the sampling values ​​of different temperature sensing elements, effective data that more closely reflects the actual wind temperature can be selected, avoiding misjudgments caused by the influence of airflow eddies on a single element). This can cover different areas of the second vent 21 along its length, avoiding the limitation that a single temperature sensing element can only capture local temperatures and cannot reflect the overall temperature difference of the wind at the second vent 21. Moreover, multiple temperature sensing elements also have a redundancy function. Even if individual temperature sensing elements fail due to aging or malfunction, the remaining temperature sensing elements arranged at intervals can still work normally to maintain basic temperature monitoring functions, avoiding the failure of the entire temperature monitoring system due to the failure of a single element, thereby effectively improving the reliability and practicality of temperature detection data.

[0041] Alternatively, multiple humidity sensing elements are arranged at intervals along the length of the circuit board 31. This arrangement facilitates multi-point humidity sampling along the length of the circuit board 31 (by comparing the sampling values ​​of different humidity sensing elements, effective data that more closely reflects the actual wind humidity can be selected, avoiding misjudgments caused by the influence of the environment on a single element). This can cover different areas of the second vent 21 along its length, avoiding the limitation that a single humidity sensing element can only capture local humidity and cannot reflect the overall humidity difference of the wind at the second vent 21. Moreover, multiple humidity sensing elements also have a redundancy function. Even if some humidity sensing elements fail due to aging or malfunction, the remaining spaced humidity sensing elements can still work normally to maintain the basic humidity monitoring function, avoiding the failure of the entire humidity monitoring system due to the failure of a single element, thereby effectively improving the reliability and practicality of humidity detection data.

[0042] According to some optional embodiments of the present invention, combined with Figure 3 and Figure 4As shown, the second arm 20 is also provided with a third air chamber 25 having a first air outlet 24. The third air chamber 25 is spaced apart from the second air chamber 22. The second vent 21 and the first air outlet 24 are spaced apart in the width direction of the second arm 20. The first air outlet 24 blows air in the width direction of the second arm 20, and the second vent 21 is located on the leeward side of the first air outlet 24. For example, the first air outlet 24 can blow out hot air.

[0043] 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 24 has the same air outlet direction as the width direction of the second arm 20 (the width direction of the second arm 20 is the same as the direction of hair straightening), the air blown out by the first air outlet 24 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.

[0044] The second vent 21 is located on the leeward side of the first air outlet 24. This avoids mutual interference between the airflow at the two vents, thus ensuring the smoothness of the air blown out of the first air outlet 24 and preventing the air blown out of the first air outlet 24 from the position of the second vent 21. This also ensures the accuracy of the detection data of the temperature and humidity sensor 30 at the second vent 21.

[0045] Alternatively, combined Figure 3 and Figure 4 As shown, the air outlet direction of the first air outlet 24 and the air outlet direction of the second air vent 21 are perpendicular to each other.

[0046] The first air outlet 24 is in the same direction as the hair straightening, and the air blown out from the first air outlet 24 can quickly straighten the hair along the straightening direction. The second air vent 21 is perpendicular to the straightening direction of the hair, and can cool down the hair after it has been styled with hot air from the first air outlet 24, thereby achieving a quick straightening and styling effect.

[0047] Alternatively, combine Figure 3 and Figure 4 As shown, the volume of the third air chamber 25 is larger than the volume of the second air chamber 22.

[0048] The third air chamber 25 is connected to the first air outlet 24, and the second air chamber 22 is connected to the second air vent 21. The second air chamber 22 and the third air chamber 25 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.

[0049] Furthermore, since the air blown out by the first air outlet 24 is mainly used to straighten the hair, the volume of the third air chamber 25 is larger than that of the second air chamber 22. This allows the third air chamber 25 to hold more air, thereby increasing the air volume of the first air outlet 24 and improving the straightening efficiency. The volume of the second air chamber 22 is smaller than that of the third air chamber 25. The smaller volume of the second air chamber 22 is suitable for accommodating the installation of the temperature and humidity sensor 30, avoiding the temperature and humidity sensor 30 occupying too much extra space. This increases the proportion of the third air chamber 25 within the limited space of the second arm 20, improving the rationality of the space layout.

[0050] Specifically, the nursing device 100 also includes a first heating element disposed in the third air chamber 25, which is used to heat the air in the third air chamber 25.

[0051] In other words, the first heating element in the third air chamber 25 can quickly heat the air in the third air chamber 25, raising the temperature of the air in the third air chamber 25, which helps to improve the drying efficiency of the hair and thus improve the speed of hair styling.

[0052] Furthermore, the first heating element includes a heating frame and a heating wire. The heating frame is disposed in the third air chamber 25 and its length direction forms an acute angle with the length direction of the second arm 20. The heating wire is wound around the outer periphery of the heating frame.

[0053] It is understandable that the length direction of the heating frame is at an acute angle to the length direction of the second arm 20, and the heating wire is wound around the outer periphery of the heating frame. In this way, the effective layout path of the heating frame and the heating wire can be extended within the limited space of the third air chamber 25, the contact area between the heating frame, the heating wire and the air can be increased, the local heat concentration and heating blind zone can be reduced, thereby effectively improving the heating efficiency and temperature uniformity of the air in the third air chamber 25.

[0054] Specifically, the bottom of the third air chamber 25 is provided with a first air inlet 251, the heating frame 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 251 and the length of the second section is less than that of the first section.

[0055] In other words, the airflow enters the third air chamber 25 from the first air inlet 251 and passes through the first section and the second section of the heating frame in sequence. Since the first section is close to the first air inlet 251, after the airflow enters from the first air inlet 251, 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 third air chamber 25 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 251 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.

[0056] 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 12.

[0057] Furthermore, combined Figure 3 , Figures 7-9 As shown, the first arm 10 is provided with a second air outlet 14 and a fourth air chamber 13 communicating with the second air outlet 14. The fourth air chamber 13 is spaced apart from the first air chamber 12. The first vent 11 and the second air outlet 14 are spaced apart in the width direction of the first arm 10. The second air outlet 14 discharges air in the width direction of the first arm 10, and the first vent 11 is located on the leeward side of the second air outlet 14. For example, the second air outlet 14 can blow out hot air.

[0058] 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 14 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 second air outlet 14 can straighten the hair to the greatest extent in the direction of straightening, thereby improving the straightening effect. Moreover, it can avoid the interference between the airflow direction and the hair straightening direction, reduce the ineffective loss of airflow and air speed, and thus improve the straightening efficiency.

[0059] Among them, combined Figure 3 , Figures 7-9 As shown, the first vent 11 is located on the leeward side of the second air outlet 14. This can avoid mutual interference between the airflows at the two outlets, thereby ensuring the smoothness of the airflow blown out by the second air outlet 14 and the first vent 11 at the same time, and avoiding airflow crosstalk.

[0060] Furthermore, combined Figure 3 , Figures 7-11As shown, the nursing device 100 also includes a second heating element 40, which is disposed in the fourth air chamber 13. The second heating element 40 is used to heat the air in the fourth air chamber 13. The second heating element 40 also includes a heating frame 41 and a heating wire. A second air inlet is provided at the bottom of the fourth air chamber 13. The heating frame 41 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 second air inlet. The length of the second section is shorter than that of the first section.

[0061] In other words, the airflow enters the fourth air chamber 13 from the second air inlet and passes through the first and second sections of the heating frame 41 in sequence. Since the first section is close to the second air inlet, after the airflow enters from the second air inlet, 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 fourth air chamber 13 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 due to continuous contact with the heating wire in the area far from the second air inlet, reducing the risk of heat accumulation, and thus making the temperature of the heated airflow more uniform and stable.

[0062] 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 12.

[0063] Alternatively, combined Figure 3 , Figures 7-11 As shown, the volume of the first air chamber 12 is smaller than that of the fourth air chamber 13. Since the air blown out by the second air outlet 14 is mainly used to straighten the hair in the direction of straightening, the volume of the fourth air chamber 13 is larger than that of the first air chamber 12. This allows the fourth air chamber 13 to hold more air, thereby increasing the air volume of the second air outlet 14 and improving the straightening efficiency. The volume of the first air chamber 12 is smaller than that of the fourth air chamber 13. The smaller volume of the first air chamber 12 can be quickly emptied or filled with airflow, thereby improving the air outlet response speed of the first vent 11 and quickly cooling the heated hair.

[0064] According to some optional embodiments of the present invention, the nursing device 100 further includes a fan assembly, a heating assembly, and a controller. The fan assembly is used to blow air into at least the first air chamber 12. The heating assembly is disposed in at least one of the first arm 10 and the second arm 20. The heating assembly is spaced apart from the fan assembly and is used to heat the hair. The controller is electrically connected to the temperature and humidity sensor 30, the fan assembly, and the heating assembly respectively, so as to control the opening and closing state and output power of the fan assembly and the heating assembly according to the temperature and humidity values ​​detected by the temperature and humidity sensor 30.

[0065] Specifically, the temperature and humidity sensor 30 is connected to the controller via an electrical signal. The detection data from the temperature and humidity sensor 30 can be directly transmitted to the controller. The controller controls the working state of the fan assembly and heating assembly 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, thus ensuring the drying rate while avoiding overheating damage. For example, when the temperature and humidity sensor 30 detects that the moisture content of the air is too high (such as after washing), the controller can control the heating assembly to automatically reduce the heating temperature or adjust the heating power to prevent high temperature from causing denaturation of hair protein and rapid moisture loss. When the temperature and humidity sensor 30 detects that the air temperature is too high, the controller can control the heating assembly to reduce the duration of high temperature and increase the power of the fan assembly to blow cool air at room temperature, reducing the risk of static electricity and breakage in the hair. This achieves personalized protection based on hair type and environment, thus achieving both styling and hair care effects.

[0066] According to some optional embodiments of the present invention, combined with Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, the nursing device 100 also includes a first hair clip 50 for holding hair. The first hair clip 50 is disposed on the first arm 10. The first hair clip 50 includes an elastic deformation portion 51. At least a portion of the elastic deformation portion 51 protrudes from the side of the first arm 10 facing the second arm 20. A cavity 511 is provided inside the elastic deformation portion 51.

[0067] Furthermore, the first hair clip 50 is disposed on the first arm 10, and at least a portion of the elastic deformation portion 51 on the first hair clip 50 protrudes from the side of the first arm 10 facing the second arm 20. This facilitates contact between the elastic deformation portion 51 and the hair. Since the elastic deformation portion 51 can undergo elastic deformation under external force, it is convenient for the elastic deformation portion 51 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.

[0068] Furthermore, since the elastic deformation part 51 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 51 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.

[0069] Optionally, the elastic deformation part 51 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.

[0070] Furthermore, combining Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, the elastic deformation part 51 has a cavity 511 inside, which makes the elastic deformation part 51 more elastic, allowing it to deform more easily and evenly under pressure, and better conform to the hair. This improves the adaptive adjustment of the clamping force of the hair care device 100, thereby enhancing the user experience. In addition, the cavity 511 helps reduce the amount of material used in the elastic deformation part 51, thus reducing manufacturing costs.

[0071] In summary, this arrangement allows the hair care device 100 to adaptively adjust the clamping force according to different hair types and amounts during the hair clamping process, avoiding problems such as hair slipping due to insufficient force or hair breaking due to excessive force. This ensures the clamping stability of different types of hair during the clamping process, and the operation process does not require the user to frequently adjust the clamping force manually, reducing the difficulty of operation.

[0072] Specifically, in combination Figure 3 As shown, the nursing device 100 also includes a second hair clip 60, which is disposed on the second arm 20. The second hair clip 60 is disposed opposite to the first hair clip 50, and at least a portion of the second hair clip 60 protrudes from the side of the second arm 20 facing the first arm 10.

[0073] Understandably, the first hair clip 50 on the first arm 10 and the second hair clip 60 on the second arm 20 are positioned opposite each other. The first hair clip 50 and the second hair clip 60 can guide the hair to enter the heating position between the two arms more smoothly. Moreover, the two working together 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.

[0074] Alternatively, the surfaces of the first hair clip 50 and the second hair clip 60 can be made of two different materials, such as at least one surface of the first hair clip 50 being made of plastic and at least one surface of the second hair clip 60 being made of metal. The first hair clip 50 prevents hair from slipping by increasing friction, while the second hair clip 60 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.

[0075] Furthermore, the second hairpin 60 has the same structure as the first hairpin 50, 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.
