Description

Technical Field

[0001] This utility model relates to the field of nursing equipment technology, and in particular to a nursing equipment. Background Technology

[0002] The hair straightener uses heating plates attached to a pivoting arm, which the user can hold in the closed position, with a strand of hair clamped between the heating plates. Once the hair is heated above the transition temperature, the strand of hair can be styled into the changed shape.

[0003] In related technologies, when hair strands are clamped between the closed arms of a hair straightener and directly heated and styled by two fixed heating plates, some hair may be styled into a bent shape. This can lead to poor straightening results and significant hair damage when straightening the hair. Therefore, there is a need to provide an improved hair styling device. Utility Model Content

[0036] 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.

[0037] Combination Figures 1-14 As shown, the nursing device 100 according to a first aspect embodiment of the present invention includes a body 4, a first arm 1, and a second arm 2. The body 4 can be configured as a load-bearing structural member of the main external contour of the nursing device 100; the first arm 1 and the second arm 2 can be connected to the body 4 by a hinge, thereby allowing them to open and close relative to each other to clamp and handle hair.

[0038] Specifically, the second arm 2 is positioned opposite to the first arm 1, and at least one of the second arm 2 and the first arm 1 is hinged to the body 4 at one end. This allows the first arm 1 and the second arm 2 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 1 and the second arm 2 according to styling needs. When the first arm 1 and the second arm 2 are open relative to each other, it is easier for the user to place the hair between the first arm 1 and the second arm 2. When the first arm 1 and the second arm 2 are closed relative to each other, the first arm 1 and the second arm 2 can clamp the hair, which is convenient for straightening the hair. It also facilitates the storage of the hair straightening tool after the straightening work is completed, reduces the space occupied by the care tool 100, and improves its practicality and flexibility of use.

[0039] In detail, a channel for receiving hair is formed between the first arm 1 and the second arm 2. 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.

[0040] Specifically, at least one of the first arm 1 and the second arm 2 is provided with an air outlet 11 for discharging air, and at least one of the first arm 1 facing the second arm 2 and the second arm 2 facing the first arm 1 is provided with an air guide channel 12 corresponding to and communicating with the air outlet 11, and air guide walls 13 for guiding air are formed on both sides of the air guide channel 12.

[0041] As arranged as described above, the air outlet 11 can be used to discharge air at a designated location. The air discharged from the air outlet 11 continues to flow along the air guide channel 12, thus forming a directional airflow. This is beneficial for users to straighten their hair by clamping it with the hair care tool 100. It also guides the airflow between the first arm 1 and the second arm 2, thereby improving the straightening effect, reducing the probability of hair curling and lifting, and accelerating the airflow speed between hair strands, thereby improving the drying efficiency of the hair and enhancing the user experience.

[0042] The guide wall 13 is located on both sides of the air guide channel 12. This can help guide the airflow to flow along the specified path, thereby improving the accuracy of the airflow direction. On the other hand, it can also reduce the probability of the airflow not flowing along the air guide channel 12, thereby improving the degree of airflow and thus effectively improving the direct generation effect.

[0043] Therefore, by setting the guide wall 13 and the air guide channel 12, the airflow can be restricted and guided during the hair straightening process, thereby avoiding airflow dispersion, improving the straightening effect, and also improving the drying efficiency of wet hair.

[0044] According to some optional embodiments of this utility model, the first arm 1 and the second arm 2 are both hinged to one end of the body 4, and the first arm 1 and the second arm 2 are both formed with air outlets 11. This can improve the flexibility of movement and opening range of the first arm 1 and the second arm 2, thereby improving the user's convenience. It can also increase the number of air outlets 11 and the uniformity of airflow distribution. That is, the hair strands held and styled by the first arm 1 and the second arm 2 have airflow on both sides, thereby effectively improving the straight hair styling effect and drying efficiency.

[0045] According to some optional embodiments of the present invention, combined with Figure 2 , Figure 6 and Figure 7As shown, the guide walls 13 on both sides of the air guide channel 12 extend along the air guide direction of the air guide channel 12, and the guide walls 13 are spaced apart along the air guide direction perpendicular to the air guide channel 12. A guide plate 14 is provided between the guide walls 13 on both sides of the air guide channel 12, and the guide walls 13 protrude from the guide plate 14 to cooperate with the guide plate 14 to form the air guide channel 12.

[0046] Specifically, the guide walls 13 on both sides of the air guide channel 12 are spaced apart along the air guide direction perpendicular to the air guide channel 12, and the guide walls 13 extend along the air guide direction of the air guide channel 12. This helps to limit the air guide cross-sectional area of ​​the air guide channel 12, thereby improving the concentration and flow intensity of the airflow when passing through the air guide channel 12. A guide plate 14 is provided between the guide walls 13 on both sides of the air guide channel 12. The guide plate 14 and the guide wall 13 are connected to each other, and the guide wall 13 protrudes from the guide plate 14. This helps the guide wall 13 and the guide plate 14 to jointly define the air guide channel 12.

[0047] According to some optional embodiments of the present invention, combined with Figure 2 , Figure 6 and Figure 7 As shown, the guide plate 14 includes a main board section 141 and an end plate section 142. The main board section 141 is constructed in the shape of a flat plate. Along the air guiding direction, the end plate section 142 is bent and connected to one end of the main board section 141. The end plate section 142 is located on one side of the air outlet 11 to guide the airflow at the air outlet 11 to the corresponding part of the air guiding channel 12 of the main board section 141.

[0048] Among them, the flat 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 flat plate shape, which can effectively increase the extension size of the main plate segment 141 without increasing the weight of the main plate segment 141, thereby reducing material consumption and improving economy. The end plate segment 142 is constructed in a bent plate shape, which can change the extension direction of the main plate segment 141 and smoothly guide the airflow.

[0049] Furthermore, along the airflow direction of the airflow channel 12, the end plate section 142 and the main plate section 141 are connected in sequence, and the end plate section 142 is bent and connected to the main plate section 141. This makes it easy for the end plate section 142 to change the extension direction of the main plate section 141. Moreover, the end plate section 142 is located on one side of the air outlet 11, which makes it easy for the airflow flowing out of the air outlet 11 to smoothly transition to the straight plate section along the end plate section 142, thereby improving the smoothness of the airflow, avoiding the airflow being blocked and causing turbulence, and thus improving the straightening effect.

[0050] Alternatively, combined Figure 2 , Figure 6 and Figure 7As shown, the guide wall 13 of the first arm 1 does not exceed the surface of the first arm 1 facing the second arm 2. This arrangement can prevent the guide wall 13 of the first arm 1 from protruding from the surface of the first arm 1 facing the second arm 2, thereby preventing the hair from being caught or tangled during operation, reducing the risk of hair getting stuck. It also makes it easier for the user to slide the hair into the hair clamping area between the two arms. Moreover, the flatter surface helps to distribute the hair more evenly, thereby achieving a better styling effect.

[0051] Alternatively, combine Figure 2 , Figure 6 and Figure 7 As shown, the guide wall 13 of the second arm 2 does not exceed the side surface of the second arm 2 facing the first arm 1. This arrangement can prevent the guide wall 13 of the second arm 2 from protruding from the side surface of the second arm 2 facing the first arm 1, thereby preventing hair from being caught or tangled during operation, reducing the risk of hair getting stuck, and making it easier for users to slide their hair into the hair clamping area between the two arms, improving the convenience and comfort of use.

[0052] According to some optional embodiments of the present invention, combined with Figure 2 and Figure 5 As shown, the width of the first arm 1 is d1, and the length of the guide wall 13 along the air guiding direction of the air guiding channel 12 is d2. d1 and d2 satisfy the relationship: 0.5d1 < d2 < 0.98d1.

[0053] Specifically, along the width direction of the first arm 1, if the length of the guide wall 13 along the airflow direction of the airflow channel 12 does not exceed half the width of the first arm 1, then the length of the guide wall 13 is too small. This will cause the airflow to be dispersed prematurely along an undesirable path outside the airflow channel 12, thereby reducing the airflow intensity. If the length d2 of the guide wall 13 along the airflow direction of the airflow channel 12 exceeds 0.98d1, then the length of the guide wall 13 is too large. This could easily lead to the shell of the first arm 1 being too thin or the bending angle of the air outlet 11 and the airflow channel 12 being too large, thereby reducing the structural reliability of the first arm 1 and the smoothness of airflow. In summary, limiting the length of the guide wall 13 along the airflow direction of the airflow channel 12 to a reasonable range can ensure the structural strength of the first arm 1 while improving the airflow intensity and smoothness. For example, the length d2 of the guide wall 13 along the air guiding direction of the air guiding channel 12 can be 0.6d1, 0.7d1, 0.8d1 and 0.9d1, and is not limited thereto.

[0054] According to some optional embodiments of the present invention, combined with Figure 2 , Figure 4 and Figure 6As shown, at least one of the first arm 1 and the second arm 2 includes an outer shell 21 and an inner shell 22. The inner shell 22 is located inside the outer shell 21 and is connected to the outer shell 21. The outer shell 21 and the inner shell 22 together form an air chamber 23, which is connected to an air outlet 11. The inner shell 22 is provided with an air outlet 11 and a guide wall 13. The air outlet 11 is located at one end of the inner shell 22, and the air guiding direction is towards the other end of the inner shell 22.

[0055] The outer shell 21 and inner shell 22 provide dual structural protection for the internal structure, enhancing structural reliability. The inner shell 22 and the outer shell 21 together form an air chamber 23 that contains gas. The air chamber 23 is connected to the air outlet 11, allowing the gas inside the air chamber 23 to be discharged through the air outlet 11. This facilitates the directional guidance of hair held between the arms, thereby improving the straightening effect.

[0056] Specifically, in combination Figure 2 and Figure 4 As shown, the nursing device 100 also includes a heating element 3, which is disposed in the air chamber 23 and is used to heat the air in the air chamber 23.

[0057] It is understandable that the heating element 3 inside the air chamber 23 can rapidly heat the gas inside the air chamber 23, thereby increasing the temperature of the gas inside the air chamber 23. This is beneficial to improving the drying efficiency of the airflow on the hair, thus increasing the speed of hair styling.

[0058] Specifically, in combination Figure 2 , Figure 6 and Figure 7 As shown, a side air outlet 211 is provided on the outer casing 21. Along the air guiding direction, the side air outlet 211 is connected to the end of the air guiding channel 12 away from the air outlet 11.

[0059] It is understandable that, along the airflow direction of the airflow channel 12, the airflow flows sequentially from the air outlet 11 to the airflow channel 12 to the side air outlet 211. This allows the airflow to flow smoothly to the outside of the care device 100 after passing through the hair, thus facilitating the continuous circulation of the airflow.

[0060] Furthermore, combined Figure 2 As shown, at least one of the first arm 1 and the second arm 2 also includes a reinforcing cover 24. At least a portion of the reinforcing cover 24 is connected to the outer periphery of the outer casing 21 near the side air outlet 211. The reinforcing cover 24 is provided with a relief opening 241 corresponding to the side air outlet 211.

[0061] In other words, since hot air may frequently pass through the side air outlet 211 on the outer casing 21 over a long period of time, a reinforcing cover 24 is provided on the outer periphery of the outer casing 21 near the side air outlet 211. The reinforcing cover 24 can increase the weight and spatial mode of the outer casing 21, thereby strengthening the structural strength and bending and torsional stiffness of the outer casing on the side of the side air outlet 211, and extending the service life of the outer casing 21. Among them, the reinforcing cover 24 is provided with a clearance opening 241, which corresponds to the side air outlet 211 on the outer casing 21. In this way, while increasing the structural strength of the outer casing 21, it can also allow airflow to be smoothly discharged from the side air outlet 211 of the outer casing 21, thereby effectively improving the design rationality of the reinforcing cover 24.

[0062] According to some optional embodiments of the present invention, combined with Figure 1 , Figure 3 , Figure 9 and Figure 10 As shown, the body 4 includes a handle inner shell 43, a fan assembly 44, a connector 45, and a three-way connector 46. The handle inner shell 43 forms an air duct 431. The fan assembly 44 is disposed in the air duct 431. The connector 45 is connected to one end of the handle inner shell 43. The three-way connector 46 is connected to the air passages of the first arm 1 and the second arm 2 respectively. The three-way connector 46 is connected to the connector 45 so as to communicate with the air duct 431 through the connector 45.

[0063] The body 4 serves as a force-bearing structure for the user's hand to grip, providing a comfortable grip. The first arm 1 and the second arm 2 are rotatably connected to the body 4, which allows the user to hold the body 4 stably while also flexibly controlling the opening and closing of the first arm 1 and the second arm 2 with their fingers.

[0064] In addition, an air duct 431 is formed inside the inner shell 43 of the handle. The air duct 431 can provide a designated flow channel for the air. The fan assembly 44 inside the air duct 431 can perform gas exchange between the inside and outside of the air duct 431 and can accelerate the surrounding air flow speed, which is conducive to the fan assembly 44 delivering airflow to the air duct 431. Along the air delivery direction of the air duct 431, one air inlet of the three-way connector 46 is connected to the connector 45, and the two air outlets of the three-way connector 46 are respectively connected to the air passages of the first arm 1 and the second arm 2. This makes it easy for the three-way connector 46 to divert the airflow in the air duct 431 to the two arms, so that both arms can achieve the effect of blowing out the guiding airflow, thereby improving the straightening efficiency.

[0065] Furthermore, the two ends of the connector 45 can be connected to the inner shell of the handle 43 and the three-way connector 46 respectively, so that the three can be connected into a whole and thus ensure overall consistency.

[0066] Alternatively, combined Figures 12-14 As shown, the inner wall of the handle inner shell 43 is provided with a first snap-fit ​​part 432, and the outer wall of the connector 45 is provided with a second snap-fit ​​part 451. The first snap-fit ​​part 432 and the second snap-fit ​​part 451 are snap-fitted together.

[0067] The above arrangement allows the handle inner shell 43 and the connector 45 to be connected as a whole through the first snap-fit ​​part 432 and the second snap-fit ​​part 451. Moreover, compared with other connection methods (such as screw connection, adhesive connection, etc.), the snap-fit ​​connection does not require additional parts to connect the handle inner shell 43 and the connector 45 as a whole, avoiding unnecessary material consumption. It can also provide sufficient holding force to ensure that the two will not loosen or fall off during use.

[0068] Moreover, the snap-fit ​​connection structure is simple and reliable, and has quick and convenient disassembly and installation functions (that is, it can realize the quick combination and separation of the handle inner shell 43 and the connector 45), which can effectively reduce the time and cost required for maintenance and replacement.

[0069] Alternatively, combine Figures 12-13 As shown, one end of the three-way connector 46 extends into the inner shell 43 of the handle, and the inner wall is provided with a third locking part 461. The outer wall of the connector 45 is provided with a fourth locking part 452. The third locking part 461 and the fourth locking part 452 are engaged.

[0070] The above arrangement allows the handle inner shell 43 and the three-way connector 46 to be connected as a whole via the third snap-fit ​​part 461 and the fourth snap-fit ​​part 452. Compared to other connection methods (such as screwing or bonding), the snap-fit ​​connection eliminates the need for additional parts, avoiding unnecessary material consumption. It also provides sufficient retaining force to ensure that the two components do not loosen or detach during use. Furthermore, the snap-fit ​​connection structure is simple, reliable, and offers quick and convenient disassembly and installation, effectively reducing maintenance and replacement time and labor costs, thus improving economic efficiency.

[0071] Specifically, in combination Figures 12-14 As shown, the handle inner shell 43 includes a first inner shell 433 and a second inner shell 434. The first inner shell 433 and the second inner shell 434 are arranged opposite to each other and are connected to each other. The first inner shell 433 is integrally formed with a flow equalization net 4331, which is located upstream of the fan assembly 44.

[0072] Understandably, the first inner shell 433 and the second inner shell 434 are detachably connected, which improves the ease of disassembly and assembly and helps reduce the time and labor costs required for maintaining and replacing the internal structural components of the handle inner shell 43. The first inner shell 433 is integrally formed with a flow equalization mesh 4331. This arrangement reduces the number of parts and assembly time, thereby reducing assembly steps, lowering manufacturing costs, and improving production efficiency. It also avoids the fitting errors that may occur in traditional multi-part assembly, thereby improving the precision and consistency of the product. Furthermore, it reduces stress concentration points (due to the absence of seams and welds), thereby improving the overall structural strength and rigidity of the first inner shell 433.

[0073] Among them, combined Figure 10 As shown, the flow equalization net 4331 is located upstream of the fan assembly 44. The flow equalization net 4331 can make the airflow entering the fan assembly 44 more uniform and stable, and avoid the phenomenon of excessively high or low airflow velocity in local areas. This helps the fan assembly 44 to work more efficiently, reduces energy loss caused by uneven airflow, and can also effectively reduce eddies and turbulence at the inlet of the fan assembly 44, thereby allowing the airflow to enter the fan assembly 44 more smoothly.

[0074] Furthermore, combined Figure 10 and Figure 12 As shown, the inner shell 43 of the handle is provided with a ventilation hole 435 communicating with the air duct 431. The nursing device 100 also includes a circuit board 6, which is disposed outside the inner shell 43 of the handle. The circuit board 6 is provided with a power component 61, which is located at the ventilation hole 435. The circuit board 6 can provide a mounting platform for electronic components and connect these components through conductive paths, so that current can flow between the components according to a predetermined design, thereby realizing a specific function.

[0075] Understandably, the ventilation hole 435 on the inner shell 43 of the handle is connected to the air duct 431. The power element 61 is mounted on the circuit board 6. Since the power element 61 emits a lot of heat, it is placed at the ventilation hole 435. In this way, the heat emitted by the power element 61 can be carried away along the air duct 431 connected to the ventilation hole 435 under the action of the fan assembly 44, thereby improving the heat dissipation effect of the power element 61. In addition, the residual heat generated by the power element 61 can also be used to heat the hair, thereby improving the drying efficiency of the hair.

[0076] According to some optional embodiments of the present invention, combined with Figure 8 and Figure 11As shown, the first arm 1 and the second arm 2 are respectively provided with locking parts 25; the nursing device 100 also includes a body 4 and a locking component 5. The first arm 1 and the second arm 2 are rotatably connected to the body 4, and the locking component 5 is slidably disposed on the body 4. The locking component 5 selectively engages with the locking part 25. The first arm 1 and the second arm 2 have a closed state when the locking component 5 is engaged with the locking part 25, and an open state when the actuator 52 is released from the locking part 25.

[0077] The body 4 serves as a force-bearing structure for the user's hand to grip, providing a comfortable grip. The first arm 1 and the second arm 2 are rotatably connected to the body 4, allowing the user to hold the body 4 stably while controlling the opening and closing of the first arm 1 and the second arm 2 with their fingers, thus improving convenience and flexibility during hair straightening. Furthermore, the body 4 is equipped with a locking component 5, which can selectively engage with the locking parts 25 on the first arm 1 and the second arm 2 to achieve a closed or open state between the first arm 1 and the second arm 2.

[0078] Specifically, the body 4 has a protrusion 41, and along the sliding direction of the locking assembly 5, the locking assembly 5 has a relief groove 5211 on the side facing the locking part 25 to avoid the protrusion 41. The relief groove 5211 on the locking assembly 5 can avoid the protrusion 41 of the body 4 in the sliding direction of the actuator 52. This avoids the risk of structural interference between the locking assembly 5, which has a certain sliding distance, and the protrusion 41 without increasing the overall length of the body 4, thereby improving the compactness and layout rationality of the nursing device 100.

[0079] Alternatively, combined Figure 8 and Figure 11 As shown, the locking assembly 5 includes an operating member 51 and an actuating member 52. The actuating member 52 is connected to the operating member 51 and is slidably disposed on the body 4 so as to selectively engage with the locking member 25.

[0080] Understandably, when the operating element 51 moves under the user's external force, the operating element 51 can transmit the force to the actuator 52. The actuator 52 moves under the drive of the operating element and can move to a position where it engages with the locking part 25. At this time, the first arm 1 and the second arm 2 are in a stable closed state, which makes it easier for the user to store the care device 100, reduce the risk of interference and collision, and improve protection. The actuator 52 can also move from the position where it engages with the locking part 25 to the position where it disengages from the locking part 25. At this time, the first arm 1 and the second arm 2 are in a relatively movable open state, which makes it easier to collect hair between the first arm 1 and the second arm 2, thereby improving the convenience for the user during the hair straightening process.

[0081] Furthermore, combined Figure 8 and Figure 11 As shown, the locking part 25 is constructed in one of the shapes of a hook and a tongue; the actuating member 52 includes a main body 521 and a mating part 522. The operating member 51 is disposed on the main body 521, which is slidably disposed on the body 4. Along the length direction of the main body 521, the mating part 522 is connected to both sides of the main body 521 near the end of the locking part 25. The other mating part 522 is constructed in one of the shapes of a hook and a tongue. For example, the locking part 25 is constructed in the shape of a hook, and the mating part 522 is constructed in the shape of a tongue; or the locking part 25 is constructed in the shape of a tongue, and the mating part 522 is constructed in the shape of a hook.

[0082] The main body 521 can serve as the main load-bearing structural component of the actuator 52. The control member 51 is connected to the main body 521, which improves the reliability of the connection between the control member 51 and the actuator 52. The main body 521 is slidably disposed on the body 4 along the length direction of the body 4 (or the length direction of the main body 521). The mating part 522 is connected to both sides of the end of the main body 521 near the locking part 25. This shortens the distance between the mating part 522 and the locking part 25, which helps the mating part 522 to establish a locking relationship with the locking part 25 more quickly, thereby improving the rationality of the design.

[0083] Furthermore, the locking part 25 is constructed as one hook and one tongue, and the mating part 522 is constructed as the other hook and one tongue. This structural feature allows the locking part 25 and the mating part 522 to achieve quick connection and separation (simply insert the tongue part into the hook part to achieve initial fixation), making the operation simple and convenient.

[0084] Specifically, in combination Figures 8-11 As shown, the body part 4 has a protrusion 41, and along the sliding direction of the actuator 52, the main body part 521 has a relief groove 5211 on the side facing the locking part 25 to avoid the protrusion 41.

[0085] It is understandable that the clearance groove 5211 on the main body 521 can avoid the protrusion 41 of the body 4 in the sliding direction of the actuator 52. In this way, without increasing the overall length of the body 4, the risk of structural interference between the actuator 52 with a certain sliding distance and the protrusion 41 can be avoided, thereby improving the compactness and rationality of the nursing device 100.

[0086] Furthermore, combined Figures 9-11 As shown, along the sliding direction of the actuator 52, one of the body part 4 and the actuator 52 is provided with two stop grooves 42, and the other of the body part 4 and the actuator 52 is provided with a stop block 523, which selectively engages with one of the two stop grooves 42 for limiting.

[0087] For example, along the sliding direction of the actuator 52, the body 4 is provided with two stop grooves 42, namely the unlocking stop groove 42 and the locking stop groove 42. The actuator 52 is provided with a stop block 523. Under the drive of the operating member 51, the actuator 52 selectively engages with one of the two stop grooves 42. When the stop block 523 engages with the unlocking stop groove 42, the actuator 52 is stably stopped at the position where it is disengaged from the locking part 25. This can avoid the risk of mis-locking of the locking assembly 5. When the stop block 523 engages with the locking stop groove 42, the actuator 52 is stably stopped at the position where it is engaged with the locking part 25. This can avoid the risk of mis-locking of the locking assembly 5, thereby ensuring the relative positional stability of the first arm 1 and the second arm 2 when they are in the closed and open states.

[0088] According to some optional embodiments of the present invention, combined with Figure 3 As shown, the care device 100 also includes a first hair-clamping component 7 and a second hair-clamping component 8. The first hair-clamping component 7 is disposed on the first arm 1, and the second hair-clamping component 8 is disposed on the second arm 2. The first hair-clamping component 7 and the second hair-clamping component 8 are disposed opposite to each other, and the first hair-clamping component 7 and the second hair-clamping component 8 are used together to clamp the hair. The first hair-clamping component 7 and the second hair-clamping component 8 are disposed on the side of the air outlet 11 away from the air guide channel 12. At least one surface of the first hair-clamping component 7 is made of metal, and at least one surface of the second hair-clamping component 8 is made of plastic.

[0089] Specifically, the first hair-clamping component 7 and the second hair-clamping component 8 are respectively disposed on the first arm 1 and the second arm 2. The first hair-clamping component 7 and the second hair-clamping component 8 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 can contact the heating area, thereby achieving a better straightening effect and user experience.

[0090] The first hair-clamping component 7 has at least one surface made of metal. Metal provides strong structural support, ensuring that it is not easily deformed or damaged during long-term use. Moreover, metal has good wear resistance and corrosion resistance, making it suitable for frequent use and extending the product's lifespan. Metal has good thermal conductivity, which helps heat to be transferred to the hair more quickly, improving heating efficiency and making the styling process faster. Metal helps maintain a consistent temperature on the surface of the heating plate, avoiding local overheating or cold spots and ensuring that the hair is heated evenly. Metal provides a relatively stable clamping force, ensuring that the hair will not easily slip during operation and helping the user better control each step of the operation.

[0091] In addition, at least one surface of the second hair-clamping component 8 is made of plastic. Plastic is usually made of soft, high-temperature resistant materials such as silicone, which can insulate the high temperature of the heating plate to a certain extent and reduce the risk of burns when the user accidentally touches it. Metal surfaces usually have a certain texture or roughness, which can increase the friction between the metal and the hair, prevent the hair from slipping out of the heating area during straightening, and improve the stability of operation. Plastic is relatively gentle and causes less damage to the hair, which helps to reduce hair breakage caused by excessive pulling or friction. The clamping force of plastic can be adjusted according to different hair types, making it more friendly to fine or fragile hair and avoiding unnecessary damage.

[0092] In summary, by using two different materials for the surfaces of the first hair-clamping component 7 and the second hair-clamping component 8, the overall user experience is improved, as well as the operational precision (the first hair-clamping component 7 ensures stable clamping force and uniform heating, while the second hair-clamping component 8 increases friction to prevent hair slippage, ensuring that each operation achieves the desired effect). Moreover, the aforementioned materials prevent excessive friction between the two hair-clamping components when clamping hair, thus avoiding the problem of users struggling to style their hair.

[0093] According to some optional embodiments of the present invention, the surface of the first hair clip member 7 is made of titanium alloy.

[0094] As described above, titanium alloy possesses extremely high strength, maintaining structural stability even at high temperatures and resisting deformation or damage. Furthermore, its low density makes the first hair-clamping component 7 both robust and lightweight, reducing the overall weight of the device and improving user comfort. Titanium alloy also exhibits excellent thermal conductivity, rapidly transferring heat from the heating element to the surface of the first hair-clamping component 7 and distributing it evenly across the entire surface. This ensures uniform heating of the hair, preventing damage caused by localized overheating. Additionally, it maintains stable physical properties over a wide temperature range, helping to maintain a constant working temperature and improve the consistency of styling results. Finally, titanium alloy is adaptable to various hair types (whether fine or coarse, providing sufficient clamping force and appropriate flexibility) to meet the needs of different users.

[0095] Optionally, the surface of the first hair-clamping component 7 is provided with a ceramic coating. The ceramic coating has good thermal conductivity, ensuring that heat is evenly distributed across the entire surface of the first hair-clamping component 7, avoiding localized overheating or cold spots, and resulting in more even heating of the hair. The ceramic coating helps the first hair-clamping component 7 reach the set temperature more quickly and cools down rapidly after use, improving work efficiency. The ceramic coating is typically very smooth, reducing friction between the first hair-clamping component 7 and the hair, preventing breakage or damage due to excessive pulling. The ceramic coating has high hardness and good wear resistance, making it less prone to scratches or peeling, thus extending the service life of the first hair-clamping component 7. The ceramic coating also reduces static electricity, preventing frizz and tangles in the hair.

[0096] Alternatively, the surface of the first hair clip member 7 is provided with a nano-coating, which has the advantages of low friction and high thermal conductivity, thereby improving the shaping effect.

[0097] Alternatively, the surface of the second hair-clamping component 8 may be provided with grooves or a honeycomb structure. The grooves or honeycomb structure can increase the contact area and friction between the surface of the second hair-clamping component 8 and the hair, allowing for a more secure grip on the hair during each operation, reducing slippage, and improving the evenness of hair heating. It can also create tiny air channels during heating, helping to dissipate excess heat, preventing localized overheating and protecting the hair from damage. Furthermore, it helps to accelerate the cooling speed of the second hair-clamping component 8 after use, reducing the risk of accidental burns to the user. Additionally, it helps to neatly arrange the hair, reducing frizz caused by irregular placement and making the hair appear smoother.

[0098] According to some optional embodiments of the present invention, combined with Figure 4As shown, the first arm 1 is provided with a limiting protrusion 15 protruding toward the second arm 2. The first hair-clamping member 7 can float elastically relative to the first arm 1. The second hair-clamping member 8 is fixedly provided. When the first arm 1 and the second arm 2 move toward each other, the second hair-clamping member 8 abuts against the limiting protrusion 15 in the width direction of the first arm 1.

[0099] As arranged as described above, when the first arm 1 and the second arm 2 move toward each other, the second hair-clamping component 8 and the limiting protrusion 15 on the first arm 1 abut against each other in the width direction of the first arm 1. This can prevent the first arm 1 and the second arm 2 from misaligning during the process of the user pulling the hair care tool 100 to straighten the hair (because the user usually pulls the hair care tool 100 downwards, the two hair-clamping components of the hair care tool 100 will be subjected to a force in the width direction, causing the two hair-clamping components to misalign to a certain extent), thereby improving the structural stability of the first arm 1 and the second arm 2 during styling.

[0100] Combination Figure 1 and Figure 3 As shown, the nursing device 100 according to the second aspect embodiment of the present invention includes a body 4, a first arm 1 and a second arm 2. The second arm 2 is disposed opposite to the first arm 1, and at least one of the second arm 2 and the first arm 1 is hinged to the body 4 at one end. The second arm 2 is rotatably connected to the first arm 1 so that the first arm 1 and the second arm 2 can move towards or away from each other. This facilitates the selective opening and closing of the first arm 1 and the second arm 2 under the action of external force, thereby enabling the user to perform the opening and closing action between the first arm 1 and the second arm 2 according to styling needs. When the first arm 1 and the second arm 2 are open relative to each other, it is easier for the user to place the hair between the first arm 1 and the second arm 2. When the first arm 1 and the second arm 2 are closed relative to each other, the first arm 1 and the second arm 2 can clamp the hair, thereby facilitating the straightening effect of the hair. It also facilitates the storage work after the user has finished straightening the hair, reduces the space occupied by the nursing device 100, and improves its practicality and flexibility of use.

[0101] In detail, at least one of the first arm 1 and the second arm 2 forms an air outlet 11 for discharging air. A guide channel 1 is provided downstream of the air outlet 11. The air outlet 11 can be used to discharge air at a designated location. The air discharged from the air outlet 11 continues to flow along the guide channel 12, thus forming a directional airflow. This is beneficial for the user to clamp and straighten the hair with the hair care device 100, and also to guide the airflow between the first arm 1 and the second arm 2, thereby improving the straightening effect of the hair, reducing the probability of hair curling and lifting, and accelerating the airflow speed between hair strands, thereby improving the drying efficiency of the hair and improving the user experience. A channel for receiving hair is formed between the first arm 1 and the second arm 2. That is, when the user uses the hair care device 100, the hair strand is captured in the channel. When the hair is pulled away from the hair care device 100 during use, the hair gradually leaves the channel.

[0102] Furthermore, the first hair-clamping component 7 on the first arm 1 and the second hair-clamping component 8 on the second arm 2 are located on the side of the air outlet 11 away from the air guide channel 12. This can help guide the airflow to pre-blow the hair bundle held by the first arm 1 and the second arm 2 to make the hair bundle straighter before the hair bundle is heated and styled by the first hair-clamping component 7 and the second hair-clamping component 8, thereby improving the styling effect.

[0103] Specifically, at least one surface of the first hair clip member 7 is made of metal, and at least one surface of the second hair clip member 8 is made of plastic.

[0104] The first hair-clamping component 7 has at least one surface made of metal. Metal provides strong structural support, ensuring that it is not easily deformed or damaged during long-term use. Moreover, metal has good wear resistance and corrosion resistance, making it suitable for frequent use and extending the product's lifespan. Metal has good thermal conductivity, which helps heat to be transferred to the hair more quickly, improving heating efficiency and making the styling process faster. Metal helps maintain a consistent temperature on the surface of the heating plate, avoiding local overheating or cold spots and ensuring that the hair is heated evenly. Metal provides a relatively stable clamping force, ensuring that the hair will not easily slip during operation and helping the user better control each step of the operation.

[0105] In addition, at least one surface of the second hair-clamping component 8 is made of plastic. Plastic is usually made of soft, high-temperature resistant materials such as silicone, which can insulate the high temperature of the heating plate to a certain extent and reduce the risk of burns when the user accidentally touches it. Metal surfaces usually have a certain texture or roughness, which can increase the friction between the metal and the hair, prevent the hair from slipping out of the heating area during straightening, and improve the stability of operation. Plastic is relatively gentle and causes less damage to the hair, which helps to reduce hair breakage caused by excessive pulling or friction. The clamping force of plastic can be adjusted according to different hair types, making it more friendly to fine or fragile hair and avoiding unnecessary damage.

[0106] Optionally, the surface of the first hair-clamping component 7 is provided with a ceramic coating. This design ensures that heat is evenly distributed across the entire surface of the first hair-clamping component 7 due to the excellent thermal conductivity of the ceramic coating, preventing localized overheating or cold spots and resulting in more even heating of the hair. The ceramic coating also helps the first hair-clamping component 7 reach the set temperature more quickly and cools rapidly after use, improving work efficiency. Furthermore, the ceramic coating is typically very smooth, reducing friction between the first hair-clamping component 7 and the hair, preventing breakage or damage due to excessive pulling. The high hardness of the ceramic coating provides good wear resistance, making it less prone to scratches or peeling, thus extending the service life of the first hair-clamping component 7.

[0107] Alternatively, the surface of the second hair-clamping component 8 may be provided with grooves or a honeycomb structure. This arrangement can effectively increase the contact area and friction between the surface of the second hair-clamping component 8 and the hair, allowing the hair to be gripped more firmly during each operation, reducing slippage, and improving the uniformity of hair heating. It can also form tiny air channels during the heating process to help dissipate excess heat, avoid local overheating, protect the hair from damage, and help accelerate the cooling speed of the second hair-clamping component 8 after use, reducing the risk of accidental burns to the user after operation. It can also help to neatly arrange the hair, reducing frizz caused by irregular placement and making the hair look smoother.

[0108] According to some optional embodiments of the present invention, the nursing device 100 further includes an elastic element disposed between the first arm 1 and the first hair-clamping member 7, so that the first hair-clamping member 7 moves in a direction toward and away from the second hair-clamping member 8.

[0109] Specifically, the elastic element can undergo elastic deformation to generate elastic force. The elastic element abuts between the first arm 1 and the first hair clamping component 7. This allows the user to change the clamping force applied to the first arm 1 and the second arm 2. In other words, the first hair clamping component 7 and the second hair clamping component 8 can automatically adjust the clamping force according to different hair types and actual hair thickness, ensuring that each hair is heated evenly. It can also avoid excessive squeezing while ensuring sufficient clamping force, avoiding unnecessary pulling or damage to the hair due to excessive clamping force. Moreover, the user does not need to manually adjust the position or force of the first hair clamping component 7 and the second hair clamping component 8. They only need to place the hair between the two hair clamping components, and the first hair clamping component 7 will automatically adjust according to the hair thickness, making the operation simpler and faster, reducing the time spent on repeated adjustments, and improving the overall styling efficiency.

[0110] Alternatively, the second hair-clamping component 8 is fixed to the second arm 2. This arrangement can reduce the number of moving parts, reduce the possibility of mechanical failure, thereby improving the overall reliability of the equipment and extending its service life. Moreover, it can ensure that the hair is clamped with the same pressure and position each time the second hair-clamping component 8 is used, thereby achieving a more uniform heating effect and avoiding local overheating or underheating caused by inconsistent clamping force, thus improving operational stability.

[0111] According to some optional embodiments of the present invention, combined with Figure 4 As shown, the first arm 1 is provided with a limiting protrusion 15 protruding toward the second arm 2. The first hair-clamping member 7 can float elastically relative to the first arm 1. The second hair-clamping member 8 is fixedly provided. When the first arm 1 and the second arm 2 move toward each other, the second hair-clamping member 8 abuts against the limiting protrusion 15 in the width direction of the first arm 1.

[0112] As arranged as described above, when the first arm 1 and the second arm 2 move toward each other, the second hair-clamping component 8 and the limiting protrusion 15 on the first arm 1 abut against each other in the width direction of the first arm 1. This can prevent the first arm 1 and the second arm 2 from misaligning during the process of the user pulling the hair care tool 100 to straighten the hair (because the user usually pulls the hair care tool 100 downwards, the two hair-clamping components of the hair care tool 100 will be subjected to a force in the width direction, causing the two hair-clamping components to misalign to a certain extent), thereby improving the structural stability of the first arm 1 and the second arm 2 during styling.

[0113] According to some optional embodiments of the present invention, combined with Figure 2 , Figure 6 and Figure 7 As shown, air guide walls 13 are formed on both sides of the air guide channel 12 to guide the air. The air guide walls 13 are located on the side of the air outlet 11 away from the first clamping member 7 or the second clamping member 8.

[0114] The guide wall 13 is located on both sides of the air guide channel 12. This can help guide the airflow to flow along the specified path, thereby improving the accuracy of the airflow direction. On the other hand, it can also reduce the probability of the airflow not flowing along the air guide channel 12, thereby improving the degree of airflow and thus effectively improving the direct generation effect.

[0115] Furthermore, the guide wall 13 is located on the side of the air outlet 11 away from the first hair clip member 7 or the second hair clip member 8. Since the first hair clip member 7 and the second hair clip member 8 need to hold the hair, the first hair clip member 7 and the second hair clip member 8 will protrude from the outer surface of the first arm 1 and the second arm 2 respectively. The first hair clip member 7 and the second hair clip member 8 will block the airflow from the air outlet. Moreover, the first hair clip member 7, the second hair clip member 8 and the guide wall 13 together restrict the flow direction of the airflow, thereby forcing the airflow to flow along the airflow direction of the air guide channel 12, thereby improving the straight hair styling effect.

[0116] Combination Figure 1 , Figure 3 and Figure 4 As shown, the nursing device 100 according to the third aspect embodiment of the present invention includes a body 4, a first arm 1 and a second arm 2. The second arm 2 is disposed opposite to the first arm 1, and at least one of the second arm 2 and the first arm 1 is hinged to the body 4 at one end. The second arm 2 is rotatably connected to the first arm 1 so that the first arm 1 and the second arm 2 can move towards or away from each other. This facilitates the selective opening and closing of the first arm 1 and the second arm 2 under the action of external force, thereby enabling the user to perform the opening and closing actions between the first arm 1 and the second arm 2 according to styling needs. When the first arm 1 and the second arm 2 are open relative to each other, it is easier for the user to place the hair between the first arm 1 and the second arm 2. When the first arm 1 and the second arm 2 are closed relative to each other, the first arm 1 and the second arm 2 can clamp the hair, thereby facilitating the straightening effect of the hair. It also facilitates the storage work after the user has finished straightening the hair, reduces the space occupied by the nursing device 100, and improves its practicality and flexibility of use.

[0117] In detail, at least one of the first arm 1 and the second arm 2 forms an air outlet 11 for discharging air. A guide channel 1 is provided downstream of the air outlet 11. The air outlet 11 can be used to discharge air at a designated location. The air discharged from the air outlet 11 continues to flow along the guide channel 12, thus forming a directional airflow. This is beneficial for the user to clamp and straighten the hair with the hair care device 100, and also to guide the airflow between the first arm 1 and the second arm 2, thereby improving the straightening effect of the hair, reducing the probability of hair curling and lifting, and accelerating the airflow speed between hair strands, thereby improving the drying efficiency of the hair and improving the user experience. A channel for receiving hair is formed between the first arm 1 and the second arm 2. That is, when the user uses the hair care device 100, the hair strand is captured in the channel. When the hair is pulled away from the hair care device 100 during use, the hair gradually leaves the channel.

[0118] Furthermore, the first hair-clamping component 7 on the first arm 1 and the second hair-clamping component 8 on the second arm 2 are located on the side of the air outlet 11 away from the air guide channel 12. This can help guide the airflow to pre-blow the hair bundle held by the first arm 1 and the second arm 2 to make the hair bundle straighter before the hair bundle is heated and styled by the first hair-clamping component 7 and the second hair-clamping component 8, thereby improving the styling effect.

[0119] In particular, combined Figure 4 As shown, the first arm 1 is provided with a limiting protrusion 15 protruding toward the second arm 2. The first hair-clamping member 7 can float elastically relative to the first arm 1. The second hair-clamping member 8 is fixedly provided. When the first arm 1 and the second arm 2 move toward each other, the second hair-clamping member 8 abuts against the limiting protrusion 15 in the width direction of the first arm 1.

[0120] As arranged as described above, when the first arm 1 and the second arm 2 move toward each other, the second hair-clamping component 8 and the limiting protrusion 15 on the first arm 1 abut against each other in the width direction of the first arm 1. This can prevent the first arm 1 and the second arm 2 from misaligning during the process of the user pulling the hair care tool 100 to straighten the hair (because the user usually pulls the hair care tool 100 downwards, the two hair-clamping components of the hair care tool 100 will be subjected to a force in the width direction, causing the two hair-clamping components to misalign to a certain extent), thereby improving the structural stability of the first arm 1 and the second arm 2 during styling.

[0121] According to some optional embodiments of the present invention, combined with Figure 1 , Figures 3-6 As shown, the second arm 2 is provided with a limiting groove 26, and the limiting protrusion 15 selectively engages with the limiting groove 26 in the width direction of the first arm 1.

[0122] For example, when the first arm 1 and the second arm 2 are closed relative to each other, the limiting groove 26 on the second arm 2 and the limiting protrusion 15 on the first arm 1 are engaged in a limiting fit in the width direction of the first arm 1. This can effectively prevent the first arm 1 and the second arm 2 from misaligning during the process of the user pulling the hair care device 100 (because the user usually pulls the hair care device 100 downwards, the two hair clamping components of the hair care device 100 will be subjected to a force in the width direction, causing the two hair clamping components to misalign to a certain extent), thereby improving the structural stability of the first arm 1 and the second arm 2 when straightening hair.

[0123] According to some optional embodiments of the present invention, the limiting protrusion 15 is attached to at least one side of the thickness direction of the first hair clip member 7. When the first hair clip member 7 and the second hair clip member 8 are in contact, the limiting protrusion 15 is attached to at least one side of the thickness direction of the first hair clip member 7 and the second hair clip member 8.

[0124] The above arrangement ensures that the limiting protrusion 15 is tightly attached to the surface of the first hair-clamping member 7 or the second hair-clamping member 8 when they come into contact, thereby preventing the formation of gaps and ensuring the reliability of the anti-misalignment effect.

[0125] According to some optional embodiments of the present invention, the nursing device 100 further includes an elastic element disposed between the first arm 1 and the first hair-clamping member 7, so that the first hair-clamping member 7 moves in a direction toward and away from the second hair-clamping member 8.

[0126] Specifically, the elastic element can deform elastically to generate elastic force. The elastic element abuts between the first arm 1 and the first hair clamping component 7. This allows the user to change the clamping force applied to the first arm 1 and the second arm 2. In other words, the first hair clamping component 7 and the second hair clamping component 8 can automatically adjust the clamping force according to the actual thickness of different hair types, ensuring that each hair is heated evenly. It can also avoid excessive squeezing while ensuring sufficient clamping force, and avoid unnecessary pulling or damage to the hair due to excessive clamping force. Moreover, the user does not need to manually adjust the position or force of the first hair clamping component 7 and the second hair clamping component 8. They only need to put the hair between the two hair clamping components, and the first hair clamping component 7 will automatically adjust according to the hair thickness, making the operation simpler and faster, reducing the time spent on repeated adjustments, and improving the overall styling efficiency.

[0127] Alternatively, the second hair-clamping component 8 is fixed to the second arm 2. This arrangement can reduce the number of moving parts, reduce the possibility of mechanical failure, thereby improving the overall reliability of the equipment and extending its service life. Moreover, it can ensure that the hair is clamped with the same pressure and position each time the second hair-clamping component 8 is used, thereby achieving a more uniform heating effect and avoiding local overheating or underheating caused by inconsistent clamping force, thus improving operational stability.

[0128] According to some optional embodiments of the present invention, there are two limiting protrusions 15. The two limiting protrusions 15 are arranged at both ends of the first hair clip member 7 along the length direction of the first hair clip member 7. This arrangement can increase the number of limiting protrusions 15, thereby improving the anti-misalignment effect of the first hair clip member 7 and the second hair clip member 8 when styling straight hair.

[0129] Specifically, the first arm 1 has an air outlet 11 for air outlet, which is located on one side of the first hair clamping member 7. The limiting protrusion 15 is between the air outlet 11 and the first hair clamping member 7, and the limiting protrusion 15 is distributed at both ends of the length direction of the air outlet 11. This arrangement can block the airflow on both sides of the air guide channel 12 to a certain extent, restricting the airflow from spreading along the air guide direction, making the airflow more concentrated and blowing towards the target area, improving the drying efficiency. It can also help to stabilize the hair directly below the air outlet 11 and prevent the hair from deviating from the optimal heating / blowing area.

[0130] According to some optional embodiments of the present invention, combined with Figure 2 , Figure 6 and Figure 7 As shown, air guide walls 13 are formed on both sides of the air guide channel 12 to guide the air. The air guide walls 13 are located on the side of the air outlet 11 away from the first clamping member 7 or the second clamping member 8.

[0131] The guide wall 13 is located on both sides of the air guide channel 12. This can help guide the airflow to flow along the specified path, thereby improving the accuracy of the airflow direction. On the other hand, it can also reduce the probability of the airflow not flowing along the air guide channel 12, thereby improving the degree of airflow and thus effectively improving the direct generation effect.

[0132] Furthermore, the guide wall 13 is located on the side of the air outlet 11 away from the first hair clip member 7 or the second hair clip member 8. Since the first hair clip member 7 and the second hair clip member 8 need to hold the hair, the first hair clip member 7 and the second hair clip member 8 will protrude from the outer surface of the first arm 1 and the second arm 2 respectively. The first hair clip member 7 and the second hair clip member 8 will block the airflow from the air outlet. Moreover, the first hair clip member 7, the second hair clip member 8 and the guide wall 13 together restrict the flow direction of the airflow, thereby forcing the airflow to flow along the airflow direction of the air guide channel 12, thereby improving the straight hair styling effect.

[0133] Specifically, at least one surface of the first hair clip member 7 is made of metal, and at least one surface of the second hair clip member 8 is made of plastic.

[0134] The surface of the first hair-clamping component 7 is made of metal. Metal provides strong structural support, ensuring that it is not easily deformed or damaged during long-term use. Moreover, metal has good wear resistance and corrosion resistance, making it suitable for frequent use and extending the product's lifespan. Metal has good thermal conductivity, which helps heat to be transferred to the hair more quickly, improving heating efficiency and making the styling process faster. Metal helps maintain a consistent temperature on the surface of the heating plate, avoiding local overheating or cold spots and ensuring that the hair is heated evenly. Metal provides a relatively stable clamping force, ensuring that the hair will not easily slip during operation and helping users better control each step of the operation.

[0135] In addition, the surface of the second hair-clamping component 8 is made of plastic. Plastic is usually made of soft, high-temperature resistant materials such as silicone, which can insulate the high temperature of the heating plate to a certain extent and reduce the risk of burns when the user accidentally touches it. Metal surfaces usually have a certain texture or roughness, which can increase the friction between the metal and the hair, prevent the hair from slipping out of the heating area during straightening, and improve the stability of the operation. Plastic is relatively gentle and causes less damage to the hair, which helps to reduce hair breakage caused by excessive pulling or friction. The clamping force of plastic can be adjusted according to different hair types, making it more friendly to fine or fragile hair and avoiding unnecessary damage.
