Description

Technical Field

[0001] This utility model relates to the technical field of hair styling tools, and in particular to a hair styling device. Background Technology

[0002] With social development and improved living standards, people's aesthetic standards have gradually risen, and individuality and fashion have become the trends pursued by contemporary beauty enthusiasts. Styling hair into various fashionable hairstyles can make people look more individualistic and enhance their beauty. Among these, curly hairstyles created using electric hair styling devices are currently one of the most popular styles.

[0003] In existing technologies, to accommodate curling irons of different diameters, the handle and heating head of current electric curling irons are detachably connected, allowing users to replace different heating head accessories. However, the electrical connection between the handle and heating head accessory in current electric curling irons is primarily through rigid contact, with no elastic deformation between the two components. This is achieved using two metal contact plates positioned at the front and back, or by metal shafts at both ends. This electrical connection method limits the dimensional control of the connection between the handle and the heating head accessory, making production difficult. Furthermore, it can easily lead to poor contact between the heating head accessory and the handle body, affecting the product's lifespan. Utility Model Content

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] See attached document Figure 1-11 A hair styling device 100 is provided in this embodiment of the present utility model.

[0045] The hair styling device 100 includes a handle 1 and a hair styling head 2. The handle 1 is equipped with a first circuit board 13, a drive mechanism 14, and a connecting assembly 20. The hair styling head 2 is detachably connected to the connecting assembly 20. The connecting assembly 20 is connected to the drive mechanism 14, and the drive mechanism 14 is electrically connected to the first circuit board 13. The hair styling head 2 rotates together with the connecting assembly 20 when the drive mechanism 14 drives it to rotate. The hair styling head 2 is equipped with a heating element 26 for generating heat. A conductive component is provided between the hair styling head 2 and the connecting assembly 20. The conductive component includes a first conductive element 171 for conducting electricity and a second conductive element 221 for conducting electricity and having elasticity. The first conductive element 171 abuts against the second conductive element 221 when the hair styling head 2 is assembled with the handle 1. The first circuit board 13 is electrically connected to the heating element 26 when it abuts against the second conductive element 221 via the first conductive element 171.

[0046] This embodiment achieves a detachable connection between the hair styling head 2 and the connecting component 20, allowing the handle 1 to be detachably connected as well. This enables the handle 1 to be used with various styles of hair styling heads 2, allowing users to adapt different hair styling heads 2 according to the degree of curl. The detachability of the hair styling head 2 and handle 1 also facilitates the carrying and transportation of this hair styling tool. Furthermore, this embodiment employs a flexible second conductive element 221 in conjunction with the first conductive element 171. This ensures tight contact between the first conductive element 171 and the second conductive element 221 during the assembly of the hair styling head 2 and the connecting component 20, preventing poor contact between the heating element 26 and the first circuit board 13. It also allows the heating element 26 to heat up under the drive of the first circuit board 13, achieving the hair styling function of the hair styling device 100. This effectively solves the problem of poor contact caused by the hard contact in the existing electrical connection between the handle 1 of the curling iron and the heated hair styling head 2 accessory. Furthermore, by utilizing the elastic second conductive element 221, the controllable range of dimensional accuracy between the connecting component 20 and the hair styling head 2 can be increased without affecting the electrical connection between the first conductive element 171 and the second conductive element 221, facilitating the manufacturing of the connecting component 20 and the hair styling head 2. Additionally, by configuring the drive mechanism 14, this embodiment allows the connecting component 20 to rotate the hair styling head 2 during operation, enabling users to curl their hair.

[0047] Specifically, the hair styling head 2 can be a straightening iron or a curling iron of different diameters for curling hair. The first conductive element 171 can be disposed on the hair styling head 2, and the second conductive element 221 can be disposed on the connecting assembly 20; or, the second conductive element 221 can be disposed on the hair styling head 2, and the first conductive element 171 can be disposed on the connecting assembly 20.

[0048] In one embodiment, each of the connecting components 20 includes a first connector 10 and a second connector 15 disposed on the handle 1. The hair styling head 2 is detachably connected to the first connector 10. The driving mechanism 14 passes through the second connector 15 and is connected to the first connector 10. The second connector 15 is fixed on the handle 1, that is, the second connector 15 does not rotate with the drive of the driving mechanism 14. When the first connector 10 is driven by the driving mechanism 14, it rotates and drives the hair styling head 2 to rotate.

[0049] A first conductive element 171 is disposed on the first connector 10, and a second conductive element 221 is disposed on the hair styling head 2. The first connector 10 has a conductive ring 160 for conducting electricity on the side near the second connector 15. The conductive ring 160 is electrically connected to the first conductive element 171, and the center of the conductive ring 160 is located on the central axis of rotation of the hair styling head 2. A third conductive element 150 with elasticity and for conducting electricity is disposed on the second connector 15. The third conductive element 150 abuts against the conductive ring 160 and is electrically connected to the first circuit board 13. That is, the first circuit board 13 is electrically connected to the first conductive element 171 after passing through the third conductive element 150 and the conductive ring 160 in sequence. When the drive mechanism 14 drives the first connector 10 to rotate, the first conductive element 171 and the conductive ring 160 rotate together. The annular conductive ring 160 ensures that it remains electrically connected to the third conductive element 150, preventing the rotation from affecting the electrical connection between the third conductive ring 160 and the first circuit board 13. Furthermore, the use of the elastic third conductive element 150 allows for tight contact with the conductive ring 160, preventing poor contact from affecting the heating element 26 driven by the first circuit board 13.

[0050] In one embodiment, the second conductive element 221 and the third conductive element 150 are both elastic probes, and the first conductive element 171 is a conductive post. Using elastic probes, after the hair styling head 2 is assembled with the connecting assembly 20, the first conductive element 171 and the second conductive element 221 can be in close contact. Of course, in other embodiments, the second conductive element 221 and the third conductive element 150 can also be spring contacts, and the first conductive element 171 can also be a metal sheet, spring contact, etc.

[0051] In one embodiment, the first conductive element 171 is recessed on the surface that abuts against the second conductive element 221, on the side away from the first conductive element 171. Specifically, the surface of the elastic probe is a convex arc surface. By making the first conductive element 171 recessed, the elastic probe can be placed in the recess, thereby increasing the contact area between the first conductive element 171 and the second conductive element 221 and improving the reliability of the electrical connection between the first conductive element 171 and the second conductive element 221.

[0052] Specifically, the cross-section of the surface of the first conductive element 171 that abuts against the second conductive element 221 is V-shaped. Of course, in other embodiments, the shape of the recess on the surface of the first conductive element 171 that abuts against the second conductive element 221 can also be a spherical surface that fits with the elastic probe.

[0053] In one embodiment, the hair styling head 2 has a connector 22 at one end near the handle 1, and the connector 22 has a plug end 222. A second conductive element 221 is disposed on the plug end 222. The connecting assembly 20 has a plug interface 181 that mates with the plug end 222. A first conductive element 171 is disposed within the plug interface 181, and the second conductive element 221 abuts against the first conductive element 171 when the plug end 222 is placed within the plug interface 181. When the hair styling head 2 is assembled with the handle 1, placing the plug end 222 within the plug interface 181 increases the connection area between the hair styling head 2 and the handle 1, thereby increasing the reliability of the connection between the hair styling head 2 and the handle 1.

[0054] In one embodiment, the connector 22 has a bayonet 223 on the outer side of the corresponding insertion end 222, and the connecting component 20 has a snap-fit ​​member 183. The snap-fit ​​member 183 is located on the first connecting member 10 near one end, and a hook 184 is located on the snap-fit ​​member 183 near the other end. The snap-fit ​​member 183 has a first pressing part 185 near the hook 184. The first connecting member 10 has a clearance opening 191 for avoiding the first pressing part 185. When the insertion end 222 is placed in the insertion interface 181, the hook 184 is placed in the bayonet 223. When the first pressing part 185 is pressed, the hook 184 disengages from the bayonet 223.

[0055] When the hair styling head 2 is assembled with the handle 1, that is, when the plug end 222 is placed in the plug interface 181, the hook 184 can be placed in the bayonet 223 to lock the connector 22 and the first connector 10 together, so as to realize the assembly of the hair styling head 2 and the handle 1. When the user needs to replace the hair styling head 2, the first pressing part 185 can be pressed, and the first pressing part 185 will drive the hook 184 to disengage from the bayonet 223. At this time, the connector 22 can be detached from the first connector, so as to realize the separation of the hair styling head 2 and the handle 1. Thus, it is convenient to install different hair styling heads 2 on the handle 1.

[0056] In other embodiments, the connector 22 and the connecting assembly 20 are detachably connected by means of magnetic attraction or pins.

[0057] In one embodiment, for the sake of the compact structure of this embodiment and to facilitate the production and manufacturing of the first connector 10, the first connector 10 includes a connector 18, a second circuit board 17 and a limiting bracket 16. The insertion interface 181 is located on the connector 18, the limiting bracket 16 is disposed at the end of the connector 18, the second circuit board 17 is located between the limiting bracket 16 and the connector 18, the first conductive element 171 is disposed on the second circuit board 17, part of the first conductive element 171 is placed inside the insertion interface 181, the conductive ring 160 is disposed on the limiting bracket 16, and the driving mechanism 14 passes through the second connector 15 and is connected to the limiting bracket 16.

[0058] In an embodiment with a snap-fit ​​connector 183, the snap-fit ​​connector 183 is disposed on the connector 18.

[0059] In one embodiment, there are four first conductive elements 171, four second conductive elements 221, four third conductive elements 150, and four conductive rings 160. Each third conductive element 150 is electrically connected to a second conductive element 221 via a conductive ring 160 and a first conductive element 171. The four conductive rings 160 are respectively a first ring body 162, a second ring body 161, a third ring body 163, and a fourth ring body 164. The first ring bodies 162, the second ring bodies 161, the third ring bodies 163, and the fourth ring bodies 164 are arranged sequentially and spaced apart on the limiting bracket 16 from the outside in, so as to separate the four conductive rings 160 and prevent the four conductive rings 160 from contacting each other. The four first conductive elements 171 are spaced apart, the four second conductive elements 221 are spaced apart, and the four third conductive elements 150 are spaced apart. The hair styling head 2 also includes a temperature sensor 25. Two second conductive elements 221 are electrically connected to the positive and negative terminals of the temperature sensor 25, and the remaining two second conductive elements 221 are electrically connected to the positive and negative terminals of the heating element 26. This allows both the heating element 26 and the temperature sensor 25 on the hair styling head 2 to be electrically connected to the first circuit board 13. The temperature sensor 25 detects the temperature of the hair styling head 2 or the heating element 26, thereby controlling the temperature of the heating element 26 and achieving temperature control of the hair styling head 2. Specifically, assuming the user controls the temperature of the hair styling head 2 or the heating element 26 to 75 degrees Celsius, the first circuit board 13 drives the heating element 26 to heat up. When the temperature of the hair styling head 2 or the heating element 26 reaches 75 degrees Celsius, the temperature sensor 25 detects the temperature of the hair styling head 2 or the heating element 26 in real time and sends an electrical signal back to the first circuit board 13. However, when the magnitude of the electrical signal received by the first circuit board 13 reaches the magnitude corresponding to the temperature reaching 75 degrees Celsius, the first circuit board 13 stops driving the heating element 26 to heat up. Conversely, when the magnitude of the electrical signal received by the first circuit board 13 does not reach the magnitude corresponding to the temperature reaching 75 degrees Celsius, the first circuit board 13 continues to drive the heating element 26 to heat up, thereby achieving temperature control of the hair styling head 2.

[0060] In one embodiment, the end of the limiting bracket 16 is provided with a first column 165 and a second column 166 located outside the first column 165. A first annular groove 168 and a second annular groove 167 are formed on the limiting bracket 16 outside the second column 166, and the first annular groove 168 and the second annular groove 167 are spaced apart. A first ring 162 is placed in the first annular groove 168, a second ring 161 is placed in the second annular groove 167, a third ring 163 is disposed on the second column 166, and a fourth ring 164 is disposed on the first column 165, so as to separate the four conductive rings 160. The limiting bracket 16 has through holes 169 at positions corresponding to the first ring 162, second ring 161, third ring 163, and fourth ring 164, respectively. A portion of each of the first ring 162, second ring 161, third ring 163, and fourth ring 164 passes through the through hole 169 and is then mounted on the second circuit board 17. This achieves electrical connection between the first ring 162, second ring 161, third ring 163, and fourth ring 164 and the second circuit board 17. Furthermore, using the wiring on the second circuit board 17, each of the first ring 162, second ring 161, third ring 163, and fourth ring 164 can be electrically connected to a first conductive element 171. This structure makes the embodiment compact and rationally laid out, allowing each of the four conductive rings 160 to be electrically connected to a first conductive element 171.

[0061] In one embodiment, a third circuit board 151 is provided at the end of the second connector 15, a third conductive element 150 is provided on the third circuit board 151, and the third circuit board 151 is electrically connected to the first circuit board 13.

[0062] In one embodiment, a third ring 163 is fitted onto the outer wall of a second pillar 166, and a fourth ring 164 is fitted onto the outer wall of a first pillar 165. The four third conductive elements 150 are a first probe 152, a second probe 155, a first clamping element 21153, and a second clamping element 21154. The first probe 152 abuts against the first ring 162, and the second probe 155 abuts against the second ring 161. The first clamping element 21153 includes a first base 1531 and two first clamping arms 1532 extending from both sides of the first base 1531, thus forming two elastic first clamping arms 1532, which are clamped onto the outer wall of the third ring 163. The second clamping member 21154 includes a second base 1542 and two second clamping arms 1541 extending from both sides of the second base 1542 to form elastic second clamping arms 1541, which are clamped on the outer side wall of the fourth ring body 164. This ensures that the conductive ring 160 is always electrically connected to the third conductive member 150, and that the electrical connection between the third conductive ring 160 and the first circuit board 13 is not affected by the rotation of the connecting assembly 20. Specifically, the first probe 152 and the second probe 155 are elastic probes.

[0063] In one embodiment, the first connector 10 further includes a connecting sleeve 19, which is connected to the connecting seat 18. The connecting sleeve 19 is located at the end of the handle 1 near the hair styling head 2, and the clearance opening 191 is located on the connecting sleeve 19. That is, when the drive mechanism 14 is driven, the connecting sleeve 19 can be rotated together through the limiting bracket 16, the second circuit board 17, and the connecting seat 18. Furthermore, by configuring the connecting sleeve 19, the hook 184 can be hidden inside the connecting sleeve 19, and combined with the clearance opening 191, the first pressing part 185 can be displayed on the outside, so that the first pressing part 185 can be easily used by the user.

[0064] In one embodiment, a first limiting block 117 is provided on the handle 1, and a second limiting block 182 is provided on the outer side wall of the first connector 10. The second limiting block 182 is located on the side of the first limiting block 117 closer to the hair styling head 2. Specifically, the second limiting block 182 is located on the outer side wall of the connecting seat 18. By cooperating with the first limiting block 117, the first connector 10 will not disengage from the handle 1 when the driving mechanism 14 drives the first connector 10, thereby improving the limiting of the first connector 10 and improving the compactness of the structure of this embodiment.

[0065] In the above embodiment, the drive mechanism 14 is a motor, and the first circuit board 13 is located at the end of the drive mechanism 14 away from the hair styling head 2, so as to shorten the distance between the first circuit board 13 and the motor and the third circuit board 151 respectively, and shorten the length of the wires electrically connected to the first circuit board 13 and the motor and the third circuit board 151 respectively.

[0066] The handle 1 is provided with a power cord 12 for connecting to a power source. The power cord 12 is electrically connected to the first circuit board 13. By connecting to a power source through the power cord 12, the first circuit board 13 can be powered on and put into operation.

[0067] In one embodiment, the handle 1 is provided with a temperature control component 115 for adjusting the heating temperature of the heating element 26 and a direction control component 113 for controlling the rotation direction of the drive mechanism 14. Both the temperature control component 115 and the direction control component 113 are electrically connected to the first circuit board 13. By operating the temperature control component 115, the heating temperature of the heating element 26 can be controlled via the first circuit board 13, thereby controlling the temperature of the hair styling head 2. By operating the direction control component 113, the motor can be controlled to rotate forward or backward via the first circuit board 13, allowing the user to control the rotation direction of the hair styling head 2 according to the direction of curling, thus improving the user experience of this embodiment.

[0068] In one embodiment, the handle 1 is further provided with a reset operation component 114 for restoring the initial state and a speed adjustment operation component 116 for adjusting the output speed of the drive mechanism 14. Both the reset operation component 114 and the speed adjustment operation component 116 are electrically connected to the first circuit board 13. By operating the speed adjustment operation component 116, the output speed of the drive mechanism 14 can be changed so that the user can adjust the desired curling speed. In this embodiment, in the initial state, the speed and temperature values ​​of the drive mechanism 14 are preset values. When the user adjusts the temperature and speed using the temperature operation component 115 and the speed adjustment operation component 116 respectively, and the user needs to restore the speed and temperature values ​​of the drive mechanism 14 to the initial state, the user can operate the reset operation component 114, which will restore the speed and temperature values ​​of the drive mechanism 14 to the preset values ​​via the first circuit board 13.

[0069] In the above embodiments, to facilitate the manufacturing of the handle 1 and the assembly of the first circuit board 13, connecting component 20, drive mechanism 14, and handle 1, the handle 1 includes a first housing 111 and a second housing 112 connected to the first housing 111. The first housing 111 and the second housing 112 are connected to accommodate the first circuit board 13, connecting component 20, and drive mechanism 14. The temperature control component 115, the operation direction control component 113, the speed control component 116, and the reset component 114 can all be one of a switch button, a DIP switch, etc.

[0070] In one embodiment, the connector 22 is rotatably provided with a clamping member 21 that cooperates with the hair styling head 2 to clamp the hair. By rotating the clamping member 21 and the connector 22, the clamping member 21 and the hair styling head 2 can cooperate to clamp the hair so that the user can style the hair.

[0071] In one embodiment, the clamping member 21 has a second pressing part 211 near the handle 1. The second pressing part 211 is mounted on the connector 22 via a shaft 213. A torsion spring 212 is sleeved on the shaft 213, and the two ends of the torsion spring 212 abut against the second pressing part 211 and the connector 22, respectively. When the user presses the second pressing part 211, the clamping member 21 can be separated from the hair styling head 2. When the user releases the pressure on the second pressing part 211, the torsion spring 212 causes the clamping member 21 to move closer to the hair styling head 2 and clamp the hair together.

[0072] In one embodiment, the hair styling head 2 includes a curling barrel 23 and two heat-conducting elements 24. A heating element 26 and the heat-conducting elements 24 are both disposed inside the curling barrel 23, with the heating element 26 located between the two heat-conducting elements 24. The two side surfaces of the heating element 26 are in contact with the two heat-conducting elements 24, and both heat-conducting elements 24 are in contact with the curling barrel 23. A connector 22 is disposed at one end of the curling barrel 23. The heat is conducted to the curling barrel 23 using the heat-conducting elements 24, allowing the user to style their hair.

[0073] In one embodiment, each heat-conducting element 24 includes a substrate 242 and two arc-shaped panels 241 extending upward from both sides of the substrate 242. Both arc-shaped panels 241 are in contact with the inner wall of the curling barrel 23. The heating element 26 is located between the two substrates 242 and in contact with the substrates 242. In this way, when the heating element 26 generates heat, the heat can be effectively transferred to the curling barrel 23 through the substrate 242 and the arc-shaped panels 241, so as to effectively utilize the heat energy generated by the heating element 26.
