Description

Technical Field

[0001] The utility model relates to the technical field related to hair processing equipment, in particular to a novel heating component and a hot air comb thereof. Background Art

[0002] Hot air combs are electrical appliances that can be used to dry hair and help style it. They are widely used in hairdressing and styling applications, such as personal care, hair salons, fashion, film and television production, and stage performances. Hot air combs can create different hairstyles to suit different hair styles.

[0003] Existing hot air combs include a handle and a comb head connected to the handle. The handle houses a fan unit for generating airflow and a heating element for heating the airflow. The comb head is equipped with multiple air outlets, bristle teeth, and soft rubber teeth. Existing heating elements are cylindrical, which requires more internal installation space. Therefore, they are typically placed inside the handle, which generally results in a longer product. If the cylindrical heating element is placed inside the comb head, the comb head becomes bulky and airflow is affected. Utility Model Content

[0004] The purpose of this application is to provide a new type of heating component and its hot air comb, which are used to solve the technical problems in the prior art that the cylindrical heating component has a large volume and poor air outlet effect due to the installation position.

[0005] To achieve at least one of the above objectives, this application provides the following technical solutions:

[0006] A new type of heating component, wherein the heating component is a long strip structure extending along a first direction, and the heating component includes an insulating member and a heating wire. The insulating member is sheet-shaped and has serrated grooves on both sides along the first direction. The heating wire is wound on the insulating member in a diamond shape in cooperation with the serrated grooves and extends along the first direction.

[0007] Preferably, two vertices of the rhombus are located in the sawtooth groove, and the other two vertices are located on both sides of the insulating member and the connecting line thereof passes through the longitudinal axis of the insulating member.

[0008] Preferably, the insulating member includes a first insulating member and a second insulating member arranged in parallel, the heating wire includes a first heating wire wound on the first insulating member and a second heating wire wound on the second insulating member, and the first heating wire and the second heating wire are arranged at intervals.

[0009] Preferably, the first heating wire is wound on the first insulating member in a first rhombus shape, and the second heating wire is wound on the second insulating member in a second rhombus shape. The shortest distance between the first heating wire and the second heating wire is L, and the L is different along the length direction of the heating component.

[0010] Preferably, 1mm≤L≤5mm.

[0011] Preferably, the heating component further includes a ceramic column, and the ceramic column is arranged between the first insulating member and the second insulating member.

[0012] Preferably, the heating component further includes an upper fixed bracket and a lower fixed bracket, the upper ends of the first insulating member and the second insulating member are respectively fixed to both sides of the upper fixed bracket, and the lower ends of the first insulating member and the second insulating member are fixed to the lower fixed bracket.

[0013] Preferably, the heating component also includes a temperature control component, a first conductive member and a second conductive member, one end of the temperature control component is riveted to the first conductive member, the first conductive member spans the first insulating member and the second insulating member and is fixedly connected to the upper fixed bracket; the temperature control component is located between the first insulating member and the second insulating member and is arranged along the first direction, the other end of the temperature control component is riveted to the second conductive member, and the second conductive member is fixedly connected to the lower fixed bracket.

[0014] Preferably, the heating component also includes a shell, which extends along the first direction, and the cross-section of the shell is C-shaped. The shell has an air outlet extending along the first direction and facing the second direction, and the second direction is perpendicular to the first direction. The lower end of the shell is provided with an air inlet.

[0015] In the above technical solution, by making the heating component into a long strip structure, the volume of the heating component is reduced, thereby reducing the volume of the entire product using the heating component; by making the heating wire wound on the insulating member in a diamond shape, only one insulating member is needed to support the heating wire, that is, avoiding contact between the heating wire and the insulating member, ensuring the reliability and stability of the cooperation between the heating wire and the insulating member, and at the same time leaving a spare area, providing a large amount of heat dissipation space for the heating wire; the diamond shape has elasticity and stronger plasticity. Compared with the circle, the size of the heating component can only be changed by changing the outer diameter. The diamond heating frame can freely adjust the values ​​in four directions. By adjusting the side length and angle of the diamond, the desired size of the heating component can be obtained; in terms of performance, the utility model winds the heating wire on the insulating member along the length direction of the heating component and makes the winding shape into a diamond. By adjusting the number of diamonds, the desired heating power is obtained, which not only maintains its own performance but also improves heat dissipation. It can greatly optimize the internal structure of the product while ensuring that the performance of the entire product does not lag behind or even exceeds that of competitors, thereby obtaining an unconventional innovative product.

[0016] A hot air comb comprises a heating component as described above, wherein the hot air comb includes a handle and a comb head connected to the handle, the heating component is arranged in the comb head, and the longitudinal axis of the heating component is the same as the longitudinal axis of the comb head.

[0017] In the above technical solution, the hot air comb product using the heating component of the utility model can effectively shorten the longitudinal length of the hot air comb compared with the product using the cylindrical heating component; moreover, the heating component is arranged in the comb head, so that the handle will not generate temperature rise due to the heating component, and at the same time the heat is concentrated in the comb head, thereby improving the styling effect.

[0041] In the description of this application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted. It should be understood that the thickness, length, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, and other dimensions of the integrated device shown in the drawings are merely illustrative and do not constitute any limitation on this application.

[0042] This application provides a novel heating component, wherein the heating component has an elongated, strip-shaped structure extending along a first direction. The heating component includes an insulating member 1 and a heating wire 2. The insulating member 1 is sheet-shaped and has sawtooth grooves 103 on both sides along the first direction. The heating wire 2 is wound around the insulating member 1 in a diamond pattern in coordination with the sawtooth grooves 103 and extends along the first direction. This type of heating component occupies a smaller installation space while ensuring the stability and reliability of the heating component, allowing for more room for innovation in products based on the heating component.

[0043] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings. The technical features involved in the different implementation modes of the present application described below can be combined with each other as long as there is no conflict between them.

[0044] like Figure 1 、 2 As shown, the heating assembly of this embodiment has an elongated strip structure extending along a first direction. The heating assembly includes an insulating member 1 and a heating wire 2. The insulating member 1 is sheet-shaped and elongated along the first direction. The insulating member 1 has sawtooth grooves 103 on both sides along the first direction. The heating wire 2 is wound around the insulating member 1 in a diamond shape in coordination with the sawtooth grooves 103 and extends along the first direction. More specifically, the insulating member 1 is a mica sheet.

[0045] By making the heating component into a long strip structure, the volume of the heating component is reduced, thereby reducing the volume of the entire product using the heating component; by making the heating wire 2 wound on the insulating member 1 in a diamond shape, only one insulating member 1 is needed to support the heating wire 2, that is, avoiding contact between the heating wire 2 and the insulating member 1, ensuring the reliability and stability of the cooperation between the heating wire 2 and the insulating member 1, and leaving a spare area, providing a large amount of heat dissipation space for the heating wire 2; the diamond shape is elastic and more malleable. Compared with the circle, the size of the heating component can only be changed by changing the outer diameter. The diamond-shaped heating frame can freely adjust the values ​​in four directions. By adjusting the side length and angle of the diamond, the desired size of the heating component can be obtained; in terms of performance, the utility model winds the heating wire 2 on the insulating member 1 along the length direction of the heating component and makes the winding shape into a diamond. By adjusting the number of diamonds, the desired heating power is obtained, which not only maintains its own performance but also improves heat dissipation. It can greatly optimize the internal structure of the product while ensuring that the performance of the entire product does not lag behind or even exceeds that of competing products, thereby obtaining an unconventional innovative product.

[0046] Two vertices of the rhombus are located within the sawtooth groove 103, and the other two vertices are located on either side of the insulating member 1, with the line connecting them passing through the longitudinal axis of the insulating member 1. This ensures that the heating wire 2 is symmetrical about the longitudinal axis of the insulating member 1. The distances between the heating wires 2 on either side of the insulating member 1 are equal, and the heat dissipation space of the heating wires 2 on both sides of the insulating member 1 is the same, thereby ensuring uniform heat dissipation of the heating wire 2 and preventing localized reddening of the heating wire 2, which could cause safety issues.

[0047] like Figures 2 to 8 As shown, the insulating member 1 includes a first insulating member 101 and a second insulating member 102 arranged in parallel. The heating wire 2 includes a first heating wire 201 wound around the first insulating member 101 and a second heating wire 202 wound around the second insulating member 102. The first heating wire 201 and the second heating wire 202 are spaced apart. This approach can increase the power of the heating component and meet diverse product requirements.

[0048] The first heating wire 201 is wound around the first insulating member 101 in a first rhombus shape, and the second heating wire 202 is wound around the second insulating member 102 in a second rhombus shape. The shortest distance between the first heating wire 201 and the second heating wire 202 is L, and L is different along the length direction of the heating component. More specifically, 1mm≤L≤3mm; preferably 1.3≤L≤1.6mm. The advantage is that the volume of the heating component can be controlled so that it occupies a smaller assembly space. When the heating component is applied to the product, the airflow flows along the length of the heating component, ensuring that the airflow takes away the heat of the heating wire 2, preventing the heating wire 2 from turning red, and improving the working reliability. If the gap is too small, the heat may not be dissipated in time, causing the heating wire 2 to turn red. If it is too close, it may also cause a short circuit. If the gap is too large, the heating component will be large in size and occupy a larger installation space, which is not conducive to product miniaturization. Furthermore, the first rhombus and the second rhombus are the same size.

[0049] The heating element further includes a supporting ceramic column 3, which is positioned between the first insulating member 101 and the second insulating member 102 to prevent deformation of the first and second insulating members 101, 102 and thereby extend the life of the heating element. More specifically, the ceramic column 3 is positioned midway between the first and second insulating members 101, 102. The first and second insulating members 101, 102 are provided with fixing holes, and the ceramic column 3 is cylindrical and securely engages with the aforementioned fixing holes.

[0050] The heating component also includes an upper fixed bracket 4 and a lower fixed bracket 5. The upper ends of the first insulating member 101 and the second insulating member 102 are respectively fixed to the two sides of the upper fixed bracket 4, and the lower ends of the first insulating member 101 and the second insulating member 102 are fixed to the lower fixed bracket 5. More specifically, the upper fixed bracket 4 is arranged between the first insulating member 101 and the second insulating member 102, and corresponding holes are provided on the upper fixed bracket 4, the first insulating member 101, and the second insulating member 102. After the holes are aligned, they are fixedly connected by rivets. In this example, the lower fixed bracket 5 is annular and cylindrical, and the inner wall of the lower fixed bracket 5 is provided with a first card slot 501 and a second card slot 502. The first insulating member 101 and the second insulating member 102 are respectively engaged with the first card slot 501 and the second card slot 502.

[0051] The heating component also includes a temperature control component 8, a first conductive member 6, and a second conductive member 7. One end of the temperature control component 8 is riveted to the first conductive member 6. The copper connecting piece spans the first insulating member 101 and the second insulating member 102 and is fixedly connected to the upper fixed bracket 4. The temperature control component 8 is located between the first insulating member 101 and the second insulating member 102 and is arranged along the first direction. The other end of the temperature control component 8 is riveted to the second conductive member 7, and the second conductive member 7 is fixedly connected to the lower fixed bracket 5. Corresponding holes are provided on the first conductive member 6, the first insulating member 101, the second insulating member 102, and the upper fixed bracket 4. After the holes are aligned, they are fixedly connected by rivets. More specifically, the temperature control component 8 includes a fuse 801 and a thermostat 802.

[0052] The heating component also includes a shell 9, which extends along a first direction. The cross-section of the shell 9 is C-shaped. The shell 9 has an air outlet 11 extending along the first direction and facing a second direction, and the second direction is perpendicular to the first direction. The lower end of the shell 9 is provided with an air inlet 10. When the heating component is applied to the product, the C-shaped side wall of the shell 9 can reduce airflow loss. In this case, the shell 9 is fixedly connected to the lower fixed bracket 5. More specifically, the spacing L1 of the heating wire 2 close to the air inlet 10 is smaller than the spacing L2 of the heating wire 2 away from the air inlet 10, wherein L1 is preferably 1.2 mm and L2 is preferably 1.5 mm.

[0053] The heating component also includes an end cap 12, which is provided on one side of the upper fixing bracket 4. The end cap 12, the housing 9, and the upper fixing bracket 4 are fixedly connected by screws. More specifically, the end of the housing 9 near the upper fixing bracket 4 is open, and the end cap 12 closes the opening. The end cap 12 and the upper fixing bracket 4 are fixedly connected by screws. It can be understood that the end of the housing 9 near the upper fixing bracket 4 is closed, and the end cap 12, the upper wall of the housing 9, and the upper fixing bracket 4 are fixedly connected by screws.

[0054] like Figure 9 、 10 As shown, a hot air comb comprises a handle 13 and a combing head 14 connected to the handle 13, the heating component is arranged in the combing head 14, the handle 13 is provided with a fan unit for forming an airflow (not shown in the figure), an air flow inlet 17 is provided below the handle, a plurality of air outlet holes 16 are provided on the combing head 14, and an air guide portion 15 is provided inside the combing head 14 relative to the air outlet to guide the airflow to the plurality of air outlet holes 16, the air guide portion 15 extends along the first direction and its length is greater than or equal to the length of the air outlet 11, which is conducive to improving the air outlet uniformity of the combing head.

[0055] Furthermore, the longitudinal axis of the heating element is aligned with the longitudinal axis of the comb head 14. This effectively shortens the longitudinal length of the hot air comb compared to products using cylindrical heating elements. Furthermore, the heating element is located within the comb head 14, preventing the handle 13 from heating up due to the heating element. Heat is then concentrated within the comb head 14, enhancing styling results.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in the various embodiments can be combined in any way.
