Description

Technical Field

[0001] The present application belongs to the technical field of hairdressing, and in particular relates to a rotating conductive structure, a handle and a hairdressing device. Background Art

[0002] Among the existing curling iron technologies, some products have a mechanical rotation function, which allows users to curl and fix their hair more conveniently during the curling process.

[0003] However, when the curling iron of the prior art rotates, its heating component rotates accordingly, which causes the wires connected to the heating component to be strained during long-term use, thereby increasing the risk of wire breakage. Once the wire breaks, it will not only affect the normal use of the curling iron, but also may cause safety hazards such as leakage or fire. Utility Model Content

[0004] In view of the above situation, it is necessary to provide a rotating conductive structure, a handle and a hairdressing device.

[0006] In the above-mentioned rotating conductive structure, when the positive pole of the power supply is connected to the first fixed part and the negative pole is connected to the second fixed part, the current passes through the first fixed part, the first rotating part, the hairdressing component, the second rotating part, and the second fixed part in sequence, and forms a series circuit with the power supply. Since the first fixed part is in contact with the first rotating part and the second fixed part is in contact with the second rotating part, when the first rotating part, the second rotating part and the hairdressing component rotate synchronously, the circuit connection can be maintained, and since the first rotating part, the second rotating part and the hairdressing component rotate synchronously, even if the first rotating part and the second rotating part are connected to the hairdressing component through wires, the wires can remain relatively straight. The first rotating part and the second rotating part are isolated by arranging an insulating member, thereby reducing the direct contact between the first rotating part and the second rotating part, which causes a short circuit.

[0007] In some embodiments of the present application, an insulating protective sleeve is also included, which has a limited rotation cavity, and the conductive rotating part is rotatably connected to the limited rotation cavity.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0063] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be a centrally arranged element at the same time. When an element is considered to be "set" on another element, it can be directly set on the other element or there may be a centrally arranged element at the same time. In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of the two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0064] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0065] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0066] In the description of the embodiments of the present application, the term "vertical" is used to describe an ideal state between two components. In actual production or use, there may be a state approximately perpendicular between the two components. For example, in combination with numerical descriptions, perpendicularity may refer to the angle between two straight lines being between 90±10°, perpendicularity may also refer to the dihedral angle between two planes being between 90°±10°, and perpendicularity may also refer to the angle between a straight line and a plane being between 90±10°. The two components described as "perpendicular" may not be absolute straight lines or planes, but may be roughly straight lines or planes. From a macroscopic point of view, the components may be considered to be "straight lines" or "planes" if the overall extension direction is a straight line or a plane.

[0067] The term "parallel" is used to describe an ideal state between two components. In actual production or use, two components may be approximately parallel. For example, combined with numerical descriptions, parallel can refer to the angle between two straight lines being between 180°±10°, parallel can also refer to the dihedral angle between two planes being between 180°±10°, and parallel can also refer to the angle between a straight line and a plane being between 180°±10°. The two components described as "parallel" may not be absolute straight lines or planes, but may be roughly straight lines or planes. From a macroscopic perspective, a component can be considered a "straight line" or a "plane" if the overall extension direction is a straight line or a plane.

[0068] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. The various embodiments in the present application may be combined with each other in the absence of conflict.

[0069] It should be noted that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary and should not constitute any limitation to the present application.

[0070] The embodiment of the present application provides a rotating conductive structure 100 . The rotating conductive structure 100 has a rotating axis 53 and includes an insulating component 30 , a conductive rotating component 10 , and a conductive fixing component 20 . The conductive rotating member 10 includes a first rotating part 11 and a second rotating part 12, the first rotating part 11 and the second rotating part 12 can rotate around the rotating axis 53, and the first rotating part 11 and the second rotating part 12 are both electrically connected to the hairdressing assembly 2000 for hair styling; the conductive fixing member 20 includes a first fixing part 21 and a second fixing part 22, the first fixing part 21 contacts the first rotating part 11, the second fixing part 22 contacts the second rotating part 12, and the conductive fixing member 20 is fixedly installed on the body; wherein the insulating member 30 isolates the first rotating part 11 from the second rotating part 12, and is used to limit the first rotating part 11 and the second rotating part 12 to prevent the conductive rotating member 10 from deforming; wherein the current passes through the first fixing part 21, the first rotating part 11, the hairdressing assembly 2000, the second rotating part 12, and the second fixing part 22 in sequence to form a series circuit with the power supply.

[0071] In the above-mentioned rotating conductive structure 100, when the positive electrode of the power source is connected to the first fixed part 21 and the negative electrode is connected to the second fixed part 22, the current passes through the first fixed part 21, the first rotating part 11, the hairdressing component 2000, the second rotating part 12, and the second fixed part 22 in sequence, and forms a series circuit with the power source. Since the first fixed part 21 is in contact with the first rotating part 11, and the second fixed part 22 is in contact with the second rotating part 12, when the first rotating part 11, the second rotating part 12 and the hairdressing component 2000 rotate synchronously, the circuit connection can be maintained, and since the first rotating part 11, the second rotating part 12 and the hairdressing component 2000 rotate synchronously, even if the first rotating part 11 and the second rotating part 12 are connected to the hairdressing component 2000 through wires, the wires can remain relatively straight. By setting the insulating member 30 to isolate the first rotating part 11 from the second rotating part 12, the direct contact between the first rotating part 11 and the second rotating part 12, which causes a short circuit, is reduced.

[0072] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0073] Overall description

[0074] See also Figure 1The embodiment of the present application provides a hairdressing device 1, which includes a handle 1000 and a hairdressing component 2000. The handle 1000 is connected to the hairdressing component 2000. The user can control the handle 1000 to rotate the hairdressing component 2000 and generate heat. The rotation of the hairdressing component 2000 can make the hair wrap around the hairdressing component 2000, and the heat generated by the hairdressing component 2000 can be transferred to the hair, so that the hair wrapped around the hairdressing component 2000 forms a curly hairdressing shape. By controlling the rotation of the hairdressing component 2000 through the handle 1000 instead of the user manually rotating the hairdressing component 2000, the hair can be more conveniently rolled and fixed.

[0075] It should be noted that the connection method between the handle 1000 and the hairdressing component 2000 is not limited. For example, the handle 1000 and the hairdressing component 2000 may be fixedly connected, and the handle 1000 and the hairdressing component 2000 are not detachable, which is conducive to improving the connection stability between the handle 1000 and the hairdressing component 2000. For another example, the handle 1000 and the hairdressing component 2000 are detachably connected, so that the user can choose different types of hairdressing components 2000 according to actual needs, so as to improve the user experience.

[0076] handle

[0077] See also Figure 2 The handle 1000 includes a rotating conductive structure 100 and a handle body 200. The rotating conductive structure 100 is installed in the handle body 200. The rotating conductive structure 100 is connected to the hairdressing component 2000. Current can be conducted between the rotating conductive structure 100 and the hairdressing component 2000.

[0078] Rotating conductive structure

[0079] Please continue reading Figures 3 to 8 The rotating conductive structure 100 includes a conductive rotating member 10 and a conductive fixing member 20, wherein the conductive rotating member 10 contacts the conductive fixing member 20, and the conductive rotating member 10 is connected to the hairdressing component 2000 and can rotate synchronously with the hairdressing component 2000. The conductive fixing member 20 is fixedly mounted on the handle body 200. The current can start from the power source and pass through the conductive fixing member 20, the conductive rotating member 10 and the hairdressing component 2000 in sequence. It should be noted that the conductive fixing member 20 is fixedly mounted on the handle body 200, which includes both direct mounting and indirect mounting.

[0080] The power source may be an external power source, or the hairdressing device 1 includes a power source such as a battery, a storage battery, etc., and the power source is installed in the handle body 200 .

[0081] Exclusive Content

[0082] Specifically, the conductive rotating member 10 includes a first rotating portion 11 and a second rotating portion 12, and the first rotating portion 11 and the second rotating portion 12 are both connected to the hairdressing component 2000. The first rotating portion 11 and the second rotating portion 12 can both rotate around the rotation axis L, that is, the first rotating portion 11, the second rotating portion 12 and the hairdressing component 2000 rotate synchronously. The first rotating portion 11 and the second rotating portion 12 are connected to the hairdressing component 2000 through wires.

[0083] The conductive fixing member 20 includes a first fixing portion 21 and a second fixing portion 22, the first fixing portion 21 contacts the first rotating portion 11, the second rotating portion 12 contacts the second fixing portion 22, and one of the first fixing portion 21 and the second fixing portion 22 is electrically connected to the positive pole of the power supply, and the other is electrically connected to the negative pole of the power supply.

[0084] When the positive electrode of the power source is electrically connected to the first fixed part 21, and the negative electrode is electrically connected to the second fixed part 22, the current passes through the first fixed part 21, the first rotating part 11, the hairdressing component 2000, the second rotating part 12, and the second fixed part 22 in sequence, thereby forming a series circuit with the power source. Since the first fixed part 21 is in contact with the first rotating part 11, and the second fixed part 22 is in contact with the second rotating part 12, when the first rotating part 11, the second rotating part 12 and the hairdressing component 2000 rotate synchronously, the series circuit can be kept connected, and since the first rotating part 11, the second rotating part 12 and the hairdressing component 2000 rotate synchronously, even if the first rotating part 11 and the second rotating part 12 are connected to the hairdressing component 2000 through wires, the wires can remain relatively straight.

[0085] The rotating conductive structure 100 further includes an insulating member 30, which isolates the first rotating portion 11 from the second rotating portion 12. The insulating member 30 is used to limit the first rotating portion 11 and the second rotating portion 12. By providing the insulating member 30 to isolate the first rotating portion 11 from the second rotating portion 12, the first rotating portion 11 and the second rotating portion 12 are reduced in direct contact with each other, thereby reducing the occurrence of a short circuit.

[0086] Optionally, along the extension direction of the rotation axis L, one end of the insulating member 30 is the first rotating portion 11 and the first fixed portion 21, and the other end is the second rotating portion 12 and the second fixed portion 22. That is, the insulating member 30 is located between the first rotating portion 11 and the second rotating portion 12, and is also located between the first fixed portion 21 and the second fixed portion 22, thereby isolating the first rotating portion 11 from the second rotating portion 12, and isolating the first fixed portion 21 from the second fixed portion 22.

[0087] Relationship between conductive rotating parts and conductive fixed parts

[0088] In some embodiments, at least one of the first rotating portion 11 and the first fixing portion 21 is an annular structure, and at least one of the second rotating portion 12 and the second fixing portion 22 is an annular structure.

[0089] Due to the annular structure, the first rotating part 11 can always be in surface contact with the first fixed part 21 during the rotation process, and the second rotating part 12 can always be in surface contact with the second fixed part 22 during the rotation process, so as to maintain circuit connectivity.

[0090] In some embodiments, the first rotating part 11, the first fixed part 21, the second rotating part 12 and the second fixed part 22 are all annular structures, and the contact area between the first rotating part 11 and the first fixed part 21 and the contact area between the second rotating part 12 and the second fixed part 22 are large, and the contact stability can be improved, reducing the occurrence of separation of the first rotating part 11 and the first fixed part 21, or separation of the second rotating part 12 and the second fixed part 22 due to shaking.

[0091] In some other embodiments, one of the first rotating part 11 and the first fixed part 21 is an annular structure, and the other is a sheet-shaped structure, and one of the second rotating part 12 and the second fixed part 22 is an annular structure, and the other is a sheet-shaped structure. Providing a sheet-shaped structure can reduce material usage and reduce weight.

[0092] First rotating part structure

[0093] In some embodiments, the first rotating portion 11 includes a first rotating ring 111 and a first conductive strip 112 , and the axis of the first rotating ring 111 coincides with the rotating axis L. The first conductive strip 112 extends along the direction of the rotating axis L and is connected to the first rotating ring 111 .

[0094] The first rotating ring 111 contacts the first fixing part 21 , and the first conductive strip 112 is connected to the hairdressing component 2000 through a wire. The current passes through the first fixing part 21 , the first rotating ring 111 , and the first conductive strip 112 in sequence and is transmitted to the hairdressing component 2000 , and then is transmitted to the second rotating part 12 and the second fixing part 22 .

[0095] The first conductive strip

[0096] In some embodiments, the first conductive strip 112 extends toward the direction close to the hairdressing component 2000 and passes through the insulating member 30 and the second rotating portion 12, thereby shortening the components with the hairdressing component 2000, shortening the length of the wire, and reducing the occurrence of the wire being entangled in the rotating conductive structure 100. It should be noted that there is a gap between the first conductive strip 112 and the second rotating portion 12, so that the first conductive strip 112 and the second rotating portion 12 do not contact each other to prevent a short circuit.

[0097] In some embodiments, the insulating member 30 is provided with a first avoidance groove 311, and the first avoidance groove 311 penetrates the insulating member 30 along the extension direction of the rotation axis L, and the second rotating portion 12 is provided with a second avoidance groove 1213, and the second avoidance groove 1213 penetrates the second rotating portion 12 along the extension direction of the rotation axis L. The first avoidance groove and the second avoidance groove 1213 are located opposite to each other. The first conductive strip 112 is penetrated through the first avoidance groove 311 and the second avoidance groove 1213, so that the first conductive strip 112 can extend toward the heating component.

[0098] First rotating ring

[0099] In some embodiments, the first rotating ring 111 is connected to the first fixing portion 21 along the extension direction of the rotating axis L, and the first fixing portion 21 is at least partially located in the first rotating ring 111. By locating the first fixing portion 21 at least partially in the first rotating ring 111, it is possible to reduce the increase in the diameter of the first fixing portion 21 after long-term use, thereby reducing the separation of the first fixing portion 21 from the first rotating ring 111.

[0100] In some embodiments, the first rotating ring 111 includes a first ring 1111 and a first stop ring 1112, and the axis of the first ring 1111 coincides with the rotation axis L. The inner surface of the first ring 1111 is in contact with the first fixing portion 21.

[0135] Insulation

[0136] The first rotating ring 111 is isolated from the second rotating ring 121 by the insulating member 30, so as to reduce the contact between the first rotating ring 111 and the second rotating ring 121, thereby reducing the possibility of a short circuit. It should be noted that since the first fixed ring 211 is located inside the first rotating ring 111 and the second fixed ring 221 is located inside the second rotating ring 121, when the first rotating ring 111 and the second rotating ring 121 are partially isolated, the first fixed ring 211 cannot contact the second fixed ring 221 or the second rotating ring 121, and correspondingly, the second fixed ring 221 cannot contact the first rotating ring 111.

[0137] Specifically, along the extension direction of the rotation axis, one end of the insulating member 30 contacts the first stop ring 1112, and the other end contacts the second stop ring 1212, thereby isolating the first rotating ring 111 from the second rotating ring 121. The second fixed ring 221 is sleeved on the insulating member 30, which can shorten the overall length of the rotating conductive structure 100 and facilitate lightweighting.

[0138] In some embodiments, the insulating member 30 includes an insulating ring 31, and the axis of the insulating ring 31 coincides with the rotation axis L.

[0140] Insulation protective cover

[0141] In some embodiments, the rotating conductive structure 100 further includes an insulating protective sleeve 40, the insulating protective sleeve 40 has a limited rotation cavity 44, and the conductive rotating member 10 is rotatably connected to the limited rotation cavity 44 to limit the displacement of the insulating member 30, the conductive rotating member 10 and the conductive fixing member 20 during the rotation process. In addition, the insulating protective sleeve 40 can also prevent the conductive fixing member 20 from rotating, so that the conductive fixing member 20 is fixed relative to the handle body 200, and the conductive rotating member 10 rotates synchronously with the hairdressing component 2000.

[0142] The insulating protective cover 40 is fixedly connected to the handle body 200 , so that the conductive fixing member 20 is indirectly fixedly mounted on the handle body 200 through the insulating protective cover 40 .

[0143] In some embodiments, the insulating protective sleeve 40 is provided with a first card slot 411 and a second card slot 412, both of which are connected to the limited rotation chamber 44, and the first connecting strip 212 is inserted into the first card slot 411 so that one end of the first connecting strip 212 away from the first fixing ring 211 extends out of the insulating protective sleeve 40, and the second connecting strip 222 is inserted into the second card slot 412 so that one end of the second connecting strip 222 away from the second fixing ring 221 extends out of the insulating protective sleeve 40. Therefore, when the first rotating part 11 and the second rotating part 12 rotate, the first fixing part 21 is blocked from rotating by the first card slot 411, and the second fixing part 22 is blocked from rotating by the second card slot 412, so that the first fixing part 21 and the second fixing part 22 can remain stable.

[0144] In some embodiments, the insulating protective cover 40 is provided with a positioning protrusion 421, and the handle body 200 is correspondingly provided with a positioning groove 61; the positioning protrusion 421 is located in the positioning groove 61, which is used to limit the limited position of the insulating protective cover 40 and the handle body 200, so that the rotating conductive structure 100 can remain fixed relative to the handle body 200.

[0149] The insulating protective sleeve 40 is sleeved on the insulating front shell 41 to limit the insulating front shell 41 to prevent the conductive rotating member 10 from moving and deforming.

[0150] The first rotating portion 11 is located between the insulating rear shell 42 and the insulating member 30 , thereby reducing the occurrence of movement of the first rotating portion 11 during the rotation process.

[0151] The positioning protrusion 421 is connected to the insulating rear shell 42 and extends from the direction perpendicular to the rotation axis L. The positioning groove 431 is located on the outer surface of the insulating sleeve 43, and the first and second grooves 411 and 412 are located on the insulating front shell 41.

[0154] In some embodiments, the rotating conductive structure 100 further includes a rotating driving unit 50 , which is disposed on the handle body 200 and connected to the conductive rotating member 10 and the hairdressing assembly 2000 to drive the conductive rotating member 10 and the hairdressing assembly 2000 to rotate.

[0155] By driving the rotation driving part 50 , the conductive rotating member 10 and the hairdressing assembly 2000 can rotate synchronously, thereby reducing the entanglement of the wires between the conductive rotating member 10 and the hairdressing assembly 2000 .

[0156] In some embodiments, the rotary drive unit 50 includes a drive source 51, a connection shell 52, and a rotating shaft 53. The drive source 51 is installed on the handle body 200 to provide power. The connection shell 52 is connected to the hairdressing component 2000. The axis of the rotating shaft 53 coincides with the rotation axis L. The rotating shaft 53 is fixedly installed on one side of the connection shell 52.

[0157] Among them, the output shaft 511 of the driving source 51 is fixedly connected to the connecting shell 52 and / or the rotating shaft 53, and the rotating shaft 53 is used to limit the insulating part 30, the first rotating part 11, and the second rotating part 12, so that when the driving source 51 drives the connecting shell 52 and / or the rotating shaft 53 to rotate, the insulating ring 31, the first rotating part 11, and the second rotating part 12 are driven to rotate synchronously.

[0158] Optionally, the output shaft 511 of the driving source 51 is passed through the rotating shaft 53 and is fixedly connected to the rotating shaft 53. The rotating shaft 53 is passed through the insulating member 30, the first rotating portion 11, the second rotating portion 12, the first fixed portion 21 and the second fixed portion 22, and cooperates with the insulating member 30, the first rotating portion 11 and the second rotating portion 12 to rotate synchronously with the rotating shaft 53.

[0159] In some embodiments, the rotating shaft 53 is provided with a first connecting groove 531 and a second connecting groove 532, and the first connecting groove 531 and the second connecting groove 532 both penetrate the rotating driving part 50 along the direction of the rotating axis L, the first conductive strip 112 is penetrated in the first connecting groove 531, and the second conductive strip 122 is penetrated in the second connecting groove 532. Thus, when the rotating driving part 50 rotates, the first rotating part 11 and the second rotating part 12 can be driven to rotate. By means of the rotating shaft 53 being penetrated in the first rotating part 11 and the second rotating part 12, and using the cooperation of the first connecting groove 531 and the second connecting groove 532 to drive the first rotating part 11 and the second rotating part 12 to rotate, the rotation stability is high.

[0160] In some embodiments, the rotating shaft 53 includes two protrusions arranged opposite to each other, the first connecting groove 531 is located on one protrusion, and the second connecting groove 532 is located on the other protrusion. The protrusion with the first connecting groove 531 is inserted into the groove matched with the second rotating part 12, thereby driving the rotating shaft 53 and the second rotating part 12 to rotate synchronously.

[0161] In some embodiments, part of the rotating shaft 53 is located on one side of the second rotating portion 12 , and the blocking protrusion 32 is located on the other side of the second rotating portion 12 , thereby limiting the position of the second rotating portion 12 and reducing the movement of the second rotating portion 12 .

[0162] In some embodiments, the insulating rear shell 42 drives the insulating rear shell 42 to press against the side of the connecting shell 52 facing away from the hairdressing assembly 2000, and the insulating front shell 41 contacts the connecting shell 52 through at least part of the contact surface to reduce the friction between the insulating front shell 41 and the connecting shell 52.

[0163] Specifically, the insulating front shell 41 is in surface contact with the connecting shell 52 through a circular annular structure, such as an annular strip with a semicircular cross-section. In this way, the contact between the insulating front shell 41 and the connecting shell 52 is ensured, and the friction between the insulating front shell 41 and the connecting shell 52 is reduced.

[0166] The handle body 200 includes a housing 60 and a control assembly 70 . The control assembly 70 and the rotating conductive structure 100 are located inside the housing 60 . The control assembly 70 is used to control the rotation of the rotating driving part 50 and control the output current of the power supply.

[0167] The outer shell 60 is formed by matching a first shell and a second shell. A positioning groove 61 and a positioning block 62 that match the insulating protective cover 40 are both located in the outer shell 60 .

By providing the rotation reset structure 80, the hairdressing component 2000 is automatically reversed and reset after rotating a preset number of times, which can reduce the situation where the hairdressing component 2000 rotates multiple times in the same direction due to user habits or misoperation. In some embodiments, the rotation reset structure 80 includes a magnetic induction sensor 81 and a magnet 82. The magnetic induction sensor 81 is embedded in one end of the handle body 200 facing the hairdressing component 2000 and is electrically connected to the first circuit board 71. The magnet 82 is embedded in one end of the hairdressing component 2000 facing the handle body 200. In the initial position, the position of the magnet 82 is opposite to the position of the magnetic induction sensor 81, and the positions of the magnet 82 and the magnetic sensor 81 deviate from the rotation axis L, so that when the magnet 82 rotates, the magnet 82 and the magnetic sensor 81 can deviate from each other.

[0173] When the hairdressing component 2000 rotates in one direction, the magnet 82 rotates with the rotation of the hairdressing component 2000, so as to be offset from the position directly opposite to the magnetic induction sensor 81. When the magnet 82 rotates one circle with the hairdressing component 2000, the magnetic induction sensor 81 counts as 1. In actual operation, the preset number of circles is 3, that is, it can be set that when the magnetic induction sensor 81 counts as 3, the first circuit board 71 controls the hairdressing component 2000 to rotate in the opposite direction, that is, the hairdressing component 2000 is reset. It should be noted that the number of preset circles is not limited, and can also be 1, 2, 4, 5, etc.
