[0040] 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.

[0041] The following is for reference. Figures 1-13 Describes a nursing device according to an embodiment of the present invention.

[0042] like Figures 1-13 As shown, the nursing device 100 includes: a blower 1, a heating component 2, and an ion generating system 3.

[0043] An air outlet 11 is provided at one end of the air duct 1, and the heating component 2 is disposed inside the air duct 1. The ion generating system 3 is at least partially disposed inside the air duct 1. In this embodiment, the ion generating system 3 is entirely disposed inside the air duct 1.

[0044] Specifically, fluid from the external environment is drawn into the blower 1. As it flows through the heating element 2, the fluid is heated, and ions generated by the ion generation system 3 mix thoroughly with the fluid before being directed towards the hair. This neutralizes the positive charges commonly found in the hair, thus smoothing out frizz and making it more manageable and sleek. It also eliminates static electricity, resulting in smoother, easier-to-comb hair and a more ideal styling effect.

[0045] Furthermore, the ion generating system 3 includes an ion generating electrode 31, the end of which facing the air outlet 11 is an emitting part 311. The emitting part 311 includes a first side 311a and a second side 311b forming a sharp angle facing the air outlet 11. Figures 5-12 As shown, the emitting part 311 of the ion generating electrode 31 is used to deliver ions to the air outlet 11. The emitting part 311 has a pointed structure formed by the first side 311a and the second side 311b. In this way, it can be ensured that the emitting part 311 can generate a sufficient negative ion concentration, which can reach at least 200 million negative ions.

[0046] Furthermore, the angle between the first side 311a and the second side 311b is α, and α satisfies the relationship: 5°≤α≤20°.

[0047] Combination Figure 11In the illustrated embodiment, the angle between the first side 311a and the second side 311b is within the range of 5°-20°. Within this angle range, the emitting part 311 has sufficient sharpness and ensures sufficient structural strength, enabling it to generate a sufficient concentration of negative ions. If the angle between the first side 311a and the second side 311b is too small, i.e., less than 5°, the sharp corner of the emitting part 311 will be extremely sharp. This not only makes it difficult to manufacture from a process perspective, but also makes the sharp corner easily damaged during transportation and assembly due to its low structural strength. If the angle between the first side 311a and the second side 311b is too large, i.e., greater than 20°, the concentration of negative ions generated by the emitting part 311 will not meet current user needs. Therefore, setting the angle between the first side 311a and the second side 311b within the range of 5°-20° can fully ensure that the emitting part 311 generates a sufficient concentration of negative ions and facilitates manufacturing and assembly.

[0048] Therefore, by reasonably setting the sharp angle range formed between the first side 311a and the second side 311b of the emitting part 311, it can be ensured that the emitting part 311 can generate a sufficient concentration of negative ions, which can then adhere to the user's hair with the fluid, thus ensuring that the hair is not frizzy. At the same time, the sharp angle structure formed by the emitting part 311 is also beneficial to manufacturing and assembly.

[0049] According to some embodiments of this utility model, α satisfies the relationship: 10°≤α≤15°. Thus, the sharpness range of the emitter 311's tip is further limited to 10°-15°, resulting in a sharper tip for the emitter 311. This not only ensures that the emitter 311 can generate a higher concentration of negative ions, but also simplifies the manufacturing process and reduces manufacturing difficulty.

[0050] According to some embodiments of the present invention, the distance between the end of the transmitter 311 facing the air outlet 11 and the air outlet 11 is d, and d satisfies the relationship: 3.5mm≤d≤10mm.

[0051] Specifically, combined Figure 12As shown, the distance between the end of the emitter 311 facing the air outlet 11 and the air outlet 11 is within the range of 3.5mm-10mm. This allows the tip of the emitter 311 to be closer to the air outlet 11, avoiding ineffective loss of negative ions. Specifically, the distance between the end of the emitter 311 facing the air outlet 11 and the air outlet 11 is at least 3.5mm to ensure that the user will not easily touch the emitter 311. Furthermore, if the distance between the end of the emitter 311 facing the air outlet 11 and the air outlet 11 is too long, there will be more ineffective loss of negative ions. Therefore, limiting the distance between the tip of the emitter 311 and the air outlet 11 to within 3.5mm-10mm ensures both safety and avoids ineffective loss of negative ions, thereby ensuring that the emitter 311 can generate a higher concentration of negative ions.

[0052] According to some embodiments of this utility model, d satisfies the relationship: 4mm≤d≤5mm.

[0053] With this configuration, the distance between the end of the emitter 311 facing the air outlet 11 and the air outlet 11 is further limited to 4mm-5mm. This shorter distance allows the tip of the emitter 311 to be closer to the air outlet 11, minimizing the loss of negative ions.

[0054] According to some embodiments of the present invention, the length of the launching part 311 from one end to the other along the axial direction of the wind tunnel 1 is h, and h satisfies the relationship: h≥5mm.

[0055] Generally, the longer the emitter 311, the higher the concentration of negative ions it can generate. (And combined with...) Figure 11 As shown, the length between the center of one end of the emitting part 311 and the center of the other end along the axial direction of the wind duct 1 is greater than or equal to 5mm. This ensures that the emitting part 311 has a wind-receiving area within the wind duct 1, thereby ensuring the generation of a higher concentration of negative ions.

[0056] According to some embodiments of this utility model, h satisfies the relationship: 7mm ≤ h ≤ 12mm. This makes the length of the emitting part 311 longer, which further ensures that the emitting part 311 can generate a higher concentration of negative ions.

[0057] Therefore, for compact high-speed care appliances (such as high-speed hair dryers), by properly setting the position and size of the ion generation system 3, it is possible to ensure that a sufficient concentration of negative ions is generated.

[0058] According to some embodiments of the present invention, the ion generating electrode 31 further includes an extension 312, which is connected to the emitting part 311, and the extension 312 extends axially along the outer wall of the heating assembly 2.

[0059] Specifically, one end of the extension 312 is used to connect to the ion generator 32 of the ion generation system 3, and the other end of the extension 312 is used to connect to the emission unit 311. The extension 312 extends axially along the outer wall of the heating assembly 2. In this way, the negative ions generated by the ion generator 32 are transferred to the emission unit 311 through the extension 312, thereby enabling the emission unit 311 to emit a sufficient concentration of negative ions.

[0060] Furthermore, at one end of the heating assembly 2 near the air outlet 11, an extension 312 extends into the heating assembly 2 to form an emitting part 311, wherein the extending direction of the emitting part 311 is at an angle to the extending direction of the extension 312.

[0061] The angles mentioned above do not include perpendicular and parallel angles; that is, the angles do not include 90° and 180°.

[0062] Specifically, combined Figures 6-9 As shown, the extension 312 extends axially along the outer wall of the heating assembly 2 to one end near the air outlet 11, and the extension 312 extends toward the inner side of the heating assembly 2 to form the emission part 311. That is, the extension direction of the extension 312 toward the inner side of the heating assembly 2 and the axial direction of the extension 312 along the outer wall of the heating assembly 2 are at an angle.

[0063] With this configuration, the extension portion 312 is arranged on the outer wall of the heating assembly 2, and the emitting portion 311 is arranged on the inner wall of the heating assembly 2. This allows the negative ions generated by the emitting portion 311 to be discharged towards the hair along with the heated fluid. Furthermore, the extending direction of the emitting portion 311 is at an angle to the extending direction of the extension portion 312, so that the angle formed between the emitting portion 311 and the extension portion 312 can be engaged with the outer wall of the heating assembly 2, thereby ensuring that the end of the ion generating electrode 31 near the air outlet 11 can be effectively fixed.

[0064] According to some embodiments of the present invention, at one end of the heating component 2 near the air outlet 11, the extension portion 312 extends into the heating component 2 in a non-radial direction to form the emitting portion 311.

[0065] With this configuration, the extension 312 extends in a non-radial direction toward the heating assembly 2 to form the emitting part 311, which ensures that the emitting part 311 is better engaged with the outer wall of the heating assembly 2 and fixed at the outer wall end. In addition, the non-radial extension also avoids the emitting part 311 occupying the space inside the heating module.

[0066] According to some embodiments of the present invention, the ion emitter is an ion emitting sheet. Thus, the sheet-like structure of the ion emitter allows the extension 312 to be attached to the outer wall of the heating assembly 2, and allows the surface of the emitting portion 311 to face the heating assembly 2 to the greatest extent possible and to have the greatest possible contact with the fluid.

[0067] According to some embodiments of the present invention, the air duct 1 includes an outer shell 12 and an inner shell 13. The heating component 2 and the inner shell 13 are disposed inside the outer shell 12. The heating component 2 is disposed at one end near the air outlet 11. The inner shell 13 is sleeved on the outer side of one end of the heating component 2 at the side near the air outlet 11. The extension 312 extends axially along the outer wall of the heating component 2 and the inner shell 13.

[0068] The heating assembly 2 includes an outer wall and a heating element, the heating element being wound circumferentially around the center of the outer wall on its inner side. The heating assembly 2 also includes multiple intersecting supports disposed within the outer wall, the center of which intersects the center of the outer wall, and the heating element is wound around these supports. In this example, the heating element is a heating wire, and the supports can be made of mica sheet material, which has high-temperature resistance. Furthermore, combined with… Figures 2-5 As shown, the extension 312 extends sequentially along the axial direction of the air duct 1, attached to the outer wall of the heating assembly 2 and the inner shell 13. The inner shell 13 supports and fixes the motor assembly and forms an air duct. The side of the inner shell 13 near the air outlet 11 is fitted onto the outer side of the outer wall of the heating module, and at least part of the outer wall of the heating assembly 2 is located within the cavity defined by the inner shell 13.

[0069] Furthermore, the extension 312 has an axial extension section 312a along the axial direction of the air duct 1 and a radial extension section 312b along the radial direction of the air duct 1. The radial extension 312 is connected between the axial extension sections 312a and is located at the connection between the heating assembly 2 and the inner shell 13. The end of the inner shell 13 near the air outlet 11 has a snap-fit ​​structure 14 for fixing the radial extension 312, and the outer side of the inner shell 13 has a mounting groove 15 for installing the ion generator 32 in the ion generation system 3.

[0070] Specifically, the extension 312 has a radial extension section 312b near the connection between the inner shell 13 and the heating assembly 2. The radial extension section 312b is formed by the extension 312 folding outward radially toward the heating assembly 2 and then continuing to extend axially along the air duct 1. A fixing member is provided near the air outlet end of the inner shell 13 to fix the inner shell 13 and the heating assembly 2. The fixing member has a snap-fit ​​structure 14. In this example, the fixing member has a snap-fit ​​structure 14 formed by a lug 14a, which snaps onto the end of the extension 312 near the heating assembly 2 to fix the extension 312 to the outer wall of the heating assembly 2. Additionally, the lower end of the inner shell 13 has a mounting groove 15 recessed into the outer wall of the inner shell 13, and the negative ion generator 32 of the negative ion assembly is disposed within the mounting groove 15.

[0071] According to some embodiments of the present invention, the first side 311a of the emitting part 311 is closer to the inner side of the heating component 2 than the second side 311b, and the length direction of the first side 311a is parallel to the extension part 312.

[0072] With this configuration, compared to the second side 311b having its length direction parallel to the extension 312, more space can be formed between the second side 311b of the emitting part 311 and the outer wall of the heating assembly 2. This makes it easier for the emitting part 311 to extend into the heating assembly 2 when it extends into the heating assembly 2 in a non-radial direction.

[0073] According to some embodiments of this utility model, the ion generating system includes two ion generating electrodes 31, and the two ion generating electrodes 31 have basically the same structure. Specifically, as shown in... Figure 6 As shown, the extensions and / or emission portions of the two ion generating electrodes 31 are parallel to each other.

[0074] According to some embodiments of the present invention, the nursing device 100 includes an air inlet 16. The nursing device 100 also includes an air inlet end cap 4 and a noise reduction component 5. The air inlet end cap 4 is connected to the air duct 1, and the noise reduction component 5 is sandwiched between the air inlet end cap 4 and the air duct 1. This arrangement, with the noise reduction component 5 sandwiched between the air inlet end cap 4 and the air duct 1, effectively reduces the noise generated during air intake.

[0075] Furthermore, the noise reduction component 5 includes a first noise reduction element 51 and a second noise reduction element 52, which are disposed opposite to each other. With this arrangement, the fluid drawn in by the motor assembly passes sequentially through the first noise reduction element 51 and the second noise reduction element 52, further reducing intake noise. In some embodiments, the first noise reduction element 51 is a sponge element, and the second noise reduction element 52 is a honeycomb mesh. With this arrangement, the first noise reduction element 51 is attached to the second noise reduction element 52, and together they are sandwiched between the air inlet end cover 4 and the air duct 1.

[0076] Furthermore, the nursing device 100 also includes a handle 6, which is connected to the air blower 1. The air blower 1 contains a motor assembly, and the handle 6 contains a control assembly. The control assembly is electrically connected to the motor assembly, the heating assembly 2, and the negative ion generating system 3, respectively.

[0077] According to a second aspect of the present invention, a nursing device 100 includes: a blower 1 with an air outlet 11 at one end; a heating assembly 2 disposed inside the blower 1; and an ion generating system 3, at least partially disposed inside the blower 1. The ion generating system 3 includes an ion generating electrode 31, the end of which facing the air outlet 11 is an emitting part 311. The ion generating electrode 31 further includes an extension 312, which is connected to the emitting part 311. The extension 312 extends axially along the outer wall of the heating assembly 2. At the end of the heating assembly 2 near the air outlet 11, the emitting part 311 extends from the extension 312 into the heating assembly 2 to form the emitting part 311, wherein the extending direction of the emitting part 311 is at an angle to the extending direction of the extension 312.

[0078] Therefore, by making an angle between the extending direction of the emitting part 311 and the extending direction of the extending part 312, the included angle formed between the emitting part 311 and the extending part 312 can be engaged with the outer wall of the heating assembly 2, thereby ensuring that the end of the ion generating electrode 31 near the air outlet 11 can be effectively fixed.

[0079] According to some embodiments of the present invention, at one end of the heating component 2 near the air outlet 11, the extension portion 312 extends into the heating component 2 in a non-radial direction to form the emitting portion 311.

[0080] With this configuration, the extension 312 extends in a non-radial direction toward the heating assembly 2 to form the emitting part 311, which ensures that the emitting part 311 is better engaged with the outer wall of the heating assembly 2 and fixed at the outer wall end. In addition, the non-radial extension also avoids the emitting part 311 occupying the space inside the heating module.

[0081] According to a third aspect embodiment of the present invention, a nursing device 100 includes: a blower 1 with an air outlet 11 at one end; a heating component 2 disposed inside the blower 1; an ion generating system 3 at least partially disposed inside the blower 1, the ion generating system 3 including an ion generating electrode 31, the end of the ion generating electrode 31 facing the air outlet 11 being an emitting part 311; the nursing device 100 includes an air inlet 16; the nursing device 100 further includes: an air inlet end cover 4 and a noise reduction component 5, the air inlet end cover 4 being connected to the blower 1, and the noise reduction component 5 being sandwiched between the air inlet end cover 4 and the blower 1; the noise reduction component 5 includes: a first noise reduction element 51 and a second noise reduction element 52, the first noise reduction element 51 and the second noise reduction element 52 being disposed opposite to each other.
