A curling iron usually consists of a handle and a barrel assembly, and the hair is styled by heating the barrel assembly.

[0019] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 As shown, a hair curler based on a probe 8 and a spring to achieve rotating electrical contact of the present invention comprises a handle assembly 10 for hand-holding, a driving mechanism and a circuit assembly are installed inside the watch assembly, and the handle assembly 10 is used as a fixing part for hand-holding when in use, and has structures such as buttons and a display screen on it, and the tail can also be connected to a power cord; It also includes a clamping drive head 20, which is used for detachably installing the curling assembly. The curling assembly can be selected according to needs, and then installed into the clamping drive head 20 to complete the installation. The two can be detachably connected, such as by using a snap or other means. The clamping drive head 20 is installed on the handle assembly 10 and connected to the driving mechanism. The clamping drive head 20 is driven by the driving mechanism to rotate in a circle. The rotation of the clamping drive head 20 can drive the rotation of the curling assembly, thereby achieving curling. like Figure 2-Figure 4As shown, the probe 8 component has one end fixedly connected to the first conductive plate 4 in the handle component 10, and the other end extends axially; and the electric contact component 5 has one end fixed to the clamping drive and connected to the output shaft 2 of the drive component, and the other end abuts against the other end of the probe 8 component in the axial direction, and the probe 8 component is in conductive contact with the electric contact component 5. When in use, the probe 8 component is fixed and the electric contact component 5 rotates in a circle, thereby realizing conductive rotation connection; like Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, it also includes two spring-type conductive fixing rings, which are fixedly mounted on the first conductive plate 4, and a conductive wrapping cavity is formed in the middle of each spring-type conductive fixing ring; and two spring-type conductive movable rings, which are fixedly connected to the clamping drive head 20, and each spring-type conductive movable ring is loaded into the conductive wrapping cavity on the corresponding side and is in conductive contact with the spring-type conductive fixing ring. The spring-type conductive movable ring can rotate relative to the circumference of the spring-type conductive fixing ring, and the circumference of the spring-type conductive movable ring is clamped and wrapped by the spring-type conductive fixing ring, so that the spring-type conductive movable ring and the spring-type conductive fixing ring can be tightly assembled together to achieve continuous conductive contact. Since the spring-type conductive fixing ring locks the circumference of the spring-type conductive movable ring, the spring-type conductive movable ring can rotate relative to a circumference of the spring-type conductive fixing ring, and continuous conductivity is achieved during the rotation process. When the spring-type conductive movable ring is loaded into the spring-type conductive fixing ring, the spring-type conductive fixing ring can be slightly stretched to obtain continuous conductivity.

[0021] Among them, Figure 3 and Figure 4 As shown, the electric contact assembly 5 includes an electric contact seat 52 and an electric contact piece 51. The electric contact seat 52 is fixedly mounted on an electric contact fixing seat 7. The electric contact fixing seat 7 is fixedly mounted inside the clamping drive head 20. The electric contact piece 51 is fixedly mounted on the electric contact seat 52. The electric contact piece 51 is a plurality of annular structures, which are arranged in a plurality of annular cavities of the electric contact seat 52. After the electric contact piece 51 is mounted on the electric contact seat 52, it is embedded in a recessed state, so that the head of the probe 8 can be inserted therein, thereby achieving the purpose of guidance.

[0022] Among them, Figure 6 As shown, a second conductive plate 6 is disposed on the side of the electric contact seat 52 facing away from the electric contact sheet 51 , and an electric contact pin 511 is disposed on the electric contact sheet 51 . The electric contact sheet 51 is connected to the second conductive plate 6 via the electric contact pin 511 .

[0023] Among them, Figure 5-Figure 8As shown, the spring-type conductive fixing ring includes a first spring-type conductive fixing ring 9 and a second spring-type conductive fixing ring 10, one end of each of the first spring-type conductive fixing ring 9 and the second spring-type conductive fixing ring 10 are fixedly connected to the first conductive plate 4, the first spring-type conductive fixing ring 9 and the second spring-type conductive fixing ring 10 are staggered in the axial direction, do not interfere with each other in position, are not affected in space, and can normally realize conductive rotation connection, the two spring-type conductive movable rings are respectively installed in the corresponding spring-type conductive fixing rings, and when the spring-type conductive movable rings rotate circumferentially, they can realize circumferential conductive contact relative to the spring-type conductive fixing rings.

[0024] In this embodiment, if Figure 6 As shown, the two spring-type conductive movable rings include a first spring-type conductive movable ring 11 and a second spring-type conductive movable ring 12 . The first spring-type conductive movable ring 11 is rotatably assembled in the first spring-type conductive fixed ring 9 , and the second spring-type conductive movable ring 12 is rotatably assembled in the second spring-type conductive fixed ring 10 .

[0025] The first spring-type conductive movable ring 11 is provided with a first connecting pin 111, and the second spring-type conductive movable ring 12 is provided with a second connecting pin 121. The first spring-type conductive movable ring 11 and the second spring-type conductive movable ring 12 are respectively connected to the second conductive plate 6 through the connecting pins, and the conductive transmission of a large current is achieved through the first spring-type conductive movable ring 11 and the second spring-type conductive movable ring 12, so that the present invention can be applied to high-power curling irons to meet the needs of more occasions.

[0026] like Figure 8 As shown, conductive contacts 13 are protrudingly provided on the inner circumferential contact surfaces of the first spring conductive fixing ring 9 and the second spring conductive fixing ring 10, and conductive contacts 13 are conductively contacted with the outer circumferential surface of the spring conductive movable ring through the conductive contacts 13. The conductive contacts 13 enable the spring conductive fixing ring and the spring conductive movable ring to always be in conductive contact, and the conductive contact effect is better. Since one end of the first spring conductive fixing ring 9 and the second spring conductive fixing ring 10 are fixedly connected to the first conductive plate 4, as long as the first spring conductive movable ring 11 and the second spring conductive movable ring 12 are always in contact with them, a movable conductive connection in the circumferential direction can be achieved.

[0027] In this embodiment, the driving mechanism includes a driving motor 1, and the output shaft 2 of the driving motor 1 passes through the first conductive plate 4 and the second conductive plate 6 and is fixedly connected to the clamping driving head 20. The driving motor 1 drives the clamping driving head 20 to rotate circumferentially, thereby driving the electric contact component 5 and the spring conductive movable ring to rotate circumferentially.

[0028] In order to fix the probe 8 assembly, in the present embodiment, the probe 8 assembly is fixedly mounted on a probe 8 mounting seat 3, and the spring needle mounting seat is fixedly mounted in the handle assembly 10 and can be fixed by screws or the like. When in use, the driving motor 1 rotates, and the motor shaft drives the electric contact assembly 5 to rotate in a circle relative to the probe 8 assembly. At the same time, the first spring conductive movable ring 11 and the second spring conductive movable ring 12 can always rotate in a circle with the first spring conductive fixed ring 9 and the second spring conductive fixed ring 10.

[0029] Among them, Figure 7 As shown, the probe 8 assembly is composed of more than one probe 8, each probe 8 is provided with a spring inside, and each probe 8 is provided with an elastic contact pin, one end of the elastic contact pin is inserted into the probe 8 and contacts the spring, and the elastic contact pin is pushed out by the spring. The elastic contact pin is always pushed out by the spring, so that the probe 8 can always be in tight contact with the conductive contact 13 for conducting electricity.

[0030] The present invention ensures that the handle assembly 10 and the reel assembly always maintain good electrical contact during the rotation process through the combined structure of the probe 8 and the spring sheet. The spring sheet conductive fixed ring and the spring sheet conductive movable ring can compensate for the contact wear caused by rotation and long-term use, thereby improving the conductive stability and extending the service life of the device. Compared with the traditional conductive contact method, the spring-type conductive fixed ring and the spring-type conductive movable ring in the present invention can provide a larger contact area, ensuring that a large current can be transmitted during the rotation process. This is especially important for curling irons that require high power output, and can ensure that the curling iron is quickly heated in a short time, thereby improving the user experience.

[0031] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
