Detailed Implementation

[0035] The specific embodiments of this utility model will now be described with reference to the accompanying drawings.

[0036] As a specific embodiment, the hair curling device of this utility model includes a carrier assembly 1, a rotating assembly 2, a heating assembly 3, and an electrical control 8.

[0037] The carrier assembly 1 includes a housing 11, which includes a gripping part 112 and a working part 111 having an external inlet 118. It is easy to understand that the gripping part 112 is for being gripped by a user.

[0038] The rotating assembly 2 includes a rotating component 21 with rotational power, and the rotating component 21 is provided with a rotating opening 218.

[0039] Heating component 3 includes a heat-generating molded part 39.

[0040] An electrical control 8 is electrically connected to an interactive device, which includes a display module. The display module includes an output device 82, or an output device 82 and an input device 81. For example, the display module may be an output device 82 such as a screen or digital tube that only has display functions; or it may be an output device 82 and an input device 81 such as a touch screen that simultaneously has input and output information functions. The input device 81 may be located on the front of the grip portion 112. All input devices 81 may be located on the front of the grip portion 112, allowing a person to operate the input devices 81 located on the front of the grip portion 112 when holding it. Typically, the external inlet 118 on the front of the grip portion 112 may also be partially located on the front of the grip portion 112.

[0041] As is easily understood, the electrical control 8 is based on existing technologies such as a circuit board, and is electrically connected to the drive device 221 and the heating element 391 described later, thereby controlling the rotation of the rotating part 21 and / or the heating of the forming part 39. The input device 81 is a device for inputting signals to the electrical control 8, such as a button or toggle switch. The output device 82 is a device for converting the signals sent to it by the electrical control 8 into optical signals, such as a digital tube or display screen.

[0042] It is easy to understand that at least a portion of the input device 81 is located on the side of the grip portion 112, i.e. Figure 1 , 2 The entire cylindrical side of the grip portion 112 shown is a superordinate concept of the front of the grip portion 112. The side of the grip portion 112 on which the input device 81 is provided is the front of the grip portion 112. Based on this, it is easy to understand that the side of the grip portion 112 opposite to the front of the grip portion 112 is the back of the grip portion 112.

[0043] like Figure 10 As shown, the hair-forming component 39, the rotating component 21, and the working part 111 are arranged sequentially from the inside out, that is, the rotating component 21 is fitted outside the hair-forming component 39, and the working part 111 is fitted outside the rotating component 21. In use, the user passes the hair through the outer hair inlet 118 and the rotating hair outlet 218, and after some hair enters the space between the rotating component 21 and the hair-forming component 39 (which has been heated by the heating element 391), the rotating component 21 is activated to rotate relative to the hair-forming component 39 (it is easy to understand that the heating element 391 is fixed relative to the working part 111). The hair is wrapped around the hair-forming component 39 and heated and shaped to achieve the curling function.

[0044] like Figure 3As shown, the outer diameter of the gripping part 112 (outer diameter 114) is smaller than the outer diameter of the working part 111 (outer diameter 113), and the output device 82 is located on the front of the working part 111. It is easy to understand that the front of the working part 111 corresponds to the front of the gripping part 112. In other words, the side of the housing 11 where the input device 81 is located is the front of the working part 111, and the front of the working part 111 includes both the front of the gripping part 112 and the front of the working part 111. It should be noted that the shapes of the working part 111 and the gripping part 112 are not limited to cylindrical shapes. The working part 111 and the gripping part 112 can also be cuboid, elliptical cylinder, or other irregular shapes with cross-sections other than rectangles or ellipses. For the aforementioned cuboid, elliptical, or irregular shapes, the corresponding diameter refers to the diameter of the center of the inscribed or circumscribed circle of the cross-section.

[0045] The working principle is as follows: during or after the user controls the heating element 391 and / or the driving device 221 (described later) through the input device 81 such as buttons, relevant information such as the temperature of the heating element 391 and the rotation position of the driving device 221 can be viewed through the output device 82, which is on the same front as the input device 81; and when viewing information through the output device 82, the user's hand holding the grip part 112 will not block the output device 82, so that the information of the curling device can be conveniently viewed during or after the operation of the curling device.

[0046] As one specific implementation, the output device 82 is provided at one end of the working part 111 near the gripping part 112. In other words, the output device 82 is provided at one end of the working part 111 near the gripping part 112.

[0047] As one specific implementation, the carrier assembly 1 further includes a light-transmitting element 17. A display opening 115 is provided at one end of the working part 111 near the holding part 112. The output device 82 faces the display opening 115. For example, the output device 82 is embedded in the display opening 115 and faces it directly. Alternatively, the output device 82 may only partially face the display opening 115, allowing that portion of the output device 82 to be visible through the display opening 115. The light-transmitting element 17 is detachably fixedly connected to one end of the working part 111 near the holding part 112 and covers the display opening 115. For example, the light-transmitting element 17 is detachably fixedly connected to one end of the working part 111 near the holding part 112 via a snap-fit ​​or similar means, and the light-transmitting element 17 completely covers the display opening 115. Typically, the outer diameter of the light-transmitting element 17 is approximately equal to the outer diameter of the working part 111, so that the working part 111 and the light-transmitting element 17 form an approximately cylindrical whole. For example, the output device 82 is a digital tube, and its setting direction is along the axis of the housing 11 (that is, the positive direction when the output device 82 is read is along the axis of the housing 11). The setting direction of the output device 82 can also be other directions. In this embodiment, when assembling the hair curling device, after the output device 82 is installed, the light-transmitting element 17 can be moved from the holding part 112 along the holding part 112 until the light-transmitting element 17 is fixed at the end of the working part 111 near the holding part 112, which can easily complete the installation of the light-transmitting element 17.

[0048] As one specific implementation, the heating assembly 3 also includes a hair-blocking component 31. The hair-blocking component 31 is fixed to one end of the hair-forming component 39 and is provided with a hair-blocking port 318. The outer hair-inlet 118, the rotating hair-inlet 218, and the hair-blocking port 318 have overlapping portions in the direction along the axis of the outer shell component 11. In other words, the outer hair-inlet 118 and the rotating hair-inlet 218 have overlapping portions in the direction along the axis of the outer shell component 11, and the overlapping portions of the outer hair-inlet 118 and the rotating hair-inlet 218 also have overlapping portions in the direction along the axis of the outer shell component 11. The front end, middle end, and end widths of the hair-blocking port 318 are respectively the front end width 312, the middle end width 313, and the end width 314. The end width 314 is less than or equal to the middle width 313, and the middle width 313 is less than the front end width 312, that is, the end width 314 < the middle width 313 ≤ the front end width 312. This implementation makes it easier for hair to enter the space between the rotating component 21 and the hair forming component 39.

[0049] As one specific implementation method, after curling is completed, the user sends a message indicating completion to the electronic control unit 8 via the input device 81, or after a set time has elapsed, the electronic control unit 8 determines that curling is complete and controls the rotating component 21 to rotate and reset, ready for the next curling session. When the rotating component 21 stops rotating, a staggered gap 6 is provided between its rotating hair opening 218 and the hair-blocking opening 318, such as... Figure 4 As shown, there is a staggered gap 6 between the center line of the rotating hair opening 218 and the center line of the hair blocking opening 318, so that the two are staggered. This embodiment makes it less likely for hair to slip out during the rotation of the rotating member 21.

[0050] As one specific implementation, the heating assembly 3 also includes a hair-blocking member 31 with a hair-blocking portion 311. The hair-blocking portion 311 extends beyond the working portion 111, and the hair-blocking portion 311 gradually approaches the axis of the working portion 111 as it moves from the working portion 111 towards the holding portion 112. During the curling process, the hair is restricted by the hair-blocking portion 311 and is not easily detached from the hair-forming member 39. When the curling stops [the rotating member 21 stops rotating], the working portion 111 moves closer to the human body, causing the hair to loosen. This allows the shaped hair to easily detach from the hair-forming member 39, thus enabling convenient curling while also facilitating the detachment of the shaped hair.

[0051] As one specific implementation, the carrier assembly 1 also includes a mounting bracket assembly 12 located within the outer casing 11. The mounting bracket assembly 12 includes an upper mounting bracket 13, a middle mounting bracket 14, and a lower mounting bracket 15 arranged sequentially. It should be emphasized that the terms "upper," "middle," and "lower" in the upper mounting bracket 13, middle mounting bracket 14, and lower mounting bracket 15 refer to their relative positions, not absolute positions. The upper mounting bracket 13, middle mounting bracket 14, and lower mounting bracket 15 are respectively fitted against the inner wall of the outer casing 11, thus fixing them relatively to each other. Of course, they can also be fixed together by screws, clips, etc. The electrical control 8 is fixed on the upper mounting bracket 13, and the power supply 83 for the battery is fixed between the middle mounting bracket 14 and the lower mounting bracket 15. In embodiments where a power connection port 839 is provided, the power connection port 839 is located on the end carrier component 16, and the end carrier component 16 is fixedly connected to the upper mounting bracket 13, middle mounting bracket 14, and lower mounting bracket 15, either directly or indirectly. The end carrier 16 can be a circuit board or a carrier for mounting the circuit board.

[0052] As one specific implementation, the rotating assembly 2 includes a rotating connector 212 and a driving device 221. The rotating output end of the driving device 221 is a driving wheel 22. The rotating assembly 21 is rotatably connected to the mounting bracket assembly 12 via the rotating connector 212. For example, the rotating connector 212 is a bearing and is mounted on the intermediate mounting bracket 14. The rotating assembly 21 includes a driven part 211 that is drivenly connected to the driving wheel 22. The driving wheel 22 and the driven part 211 can be a gear and gear ring meshing structure, a friction wheel abutting against the inner wall of the ring, or other existing technologies. The electrical control 8 is electrically connected to a power source 83, which is a battery. The driving device 221 is fixed on the intermediate mounting bracket 14. The intermediate mounting bracket 14 has a portion located between the driving device 221 and the power source 83. In other words, as shown in the figure... Figure 11 As shown, the drive unit 221 and the power supply 83 are separated by the aforementioned portion of the mounting bracket 14. In this embodiment, the mounting bracket assembly 12 and the rotating assembly 2 can be assembled as a single unit and then inserted into the outer casing 11, facilitating the assembly of the hair curling device. The rotating assembly 21 is provided with a heat dissipation vent 213 to increase the speed at which the hair forming component 39 dissipates heat.

[0053] In one specific implementation, the inner cavity of the driven part 211 is annular. The driving wheel 22 contacts the inner wall of the driven part 211 and is driven by the driven part 211. The hair-forming part 39 is fixedly connected to the middle mounting bracket 14. For example, the middle mounting bracket 14 is fixedly provided with a connecting screw 149. Between the connecting screw 149 and the inner wall of the hair-forming part 39, from the inside out, there are spring pieces (not shown in the figure), a heat insulation frame 392, a silicone pad 393, and a heating element 391 that is a heating film. Under the elastic force of the spring pieces, the heat insulation frame abuts the heating element 391, which is a heating film, against the inner wall of the hair-forming part 39, so that the heating element 391 can heat the hair-forming part 39 up close. This implementation can ensure that the rotating part 21 and the hair-blocking part 31 are coaxial and ensure the curling effect.

[0054] As one specific implementation, the hair curling device also includes a negative ion device 7 with a negative ion output line 71. It is readily understood that the negative ion device 7 is electrically connected to the control unit 8, and generates negative ions through the negative ion output line 71 and / or its components, as per existing technology. The portion of the negative ion output line 71 that generates negative ions and / or its components are located at the end of the negative ion output line 71. The negative ion device 7 is fixed to the middle mounting bracket 14, for example, embedded in the middle mounting bracket 14. The lower mounting bracket 15 is provided with an inlet hole 151, an outlet hole 152, and a mounting groove 153. The negative ion output line 71 extends out of the side of the lower mounting bracket 15 and passes sequentially through the inlet hole 151 and the outlet hole 152, with a portion located within the groove 153. The lower mounting bracket 15 is provided with a wire positioning groove 154 for fixing the negative ion output line 71; the outer wall of the lower mounting bracket 15 is provided with a wiring groove 155 facing the outlet hole 152; the wiring groove 155 is used to accommodate the negative ion output line 71. This implementation method can prevent the negative ion output line 71 from being squeezed and damaged.

[0055] As one specific implementation, the input device 81 includes an angle sensor 811 for detecting the rotation angle of the driven part 211; for example, the angle sensor 811 is a Hall sensor, and the driven part 211 is provided with a magnetic device 812, such as a magnet. In this embodiment, the angle sensor 811 transmits an electrical signal to the electrical control 8, which controls the drive device 221, thereby controlling the position of the hair-retaining opening 218 of the rotating part 21 when the rotating part 21 stops rotating; in addition, if hair gets stuck on the rotating part 21, preventing it from rotating, the angle sensor 811 transmits an electrical signal to the electrical control 8, which then controls the drive device 221 to stop, thus preventing hair from getting tangled on the rotating part 21 and / or the hair-blocking part 311.

[0056] The terms used in this invention, such as "first," "second," etc., do not indicate any order, quantity, or importance, but are merely for distinction.

[0057] In this invention, terms such as "a" or "an" are used to indicate not a limitation on the quantity, but rather to indicate the existence of at least one of the mentioned objects.

[0058] In this utility model, terms indicating direction or location such as top, bottom, side, longitudinal, transverse, middle, center, outside, inside, horizontal, vertical, left, right, above, and below are used to indicate relative positions rather than absolute positions.

[0059] Terms used in this invention, such as "approximately," "generally," "approximately," and "similar," are limiting terms used to indicate features that are present but allow for certain deviations. The amount of deviation allowed may vary depending on the specific context; for example, regarding dimensional deviations, the specific context may include, but is not limited to, relevant standards for dimensional tolerances.
