[0007] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0008] An automatic hair curling iron, comprising:

[0009] The housing comprises a cylindrical curling portion, wherein a trumpet-shaped through groove is provided in the cylindrical wall of the curling portion along the axial direction;

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] The core of the utility model is to provide an automatic curling iron. By providing a trumpet-shaped through-groove on the curling part to facilitate the entry of hair into the curling iron, a limiting component is added to limit the roots of hair entering the curling iron to prevent them from rotating with the hair-pulling component, thereby solving the problem that hard hair is difficult to be entangled in the curling iron.

[0037] Please refer to Figures 1-6 , an automatic curling iron, comprising:

[0038] The housing 1 includes a cylindrical curling portion 101, and a trumpet-shaped through groove 106 is provided on the cylindrical wall of the curling portion 101 along the axial direction;

[0039] The heating tube 2 is coaxially fixedly disposed inside the curling part 101;

[0040] The hair-pulling assembly 3 is coaxially mounted on the outside of the heating tube 2, and a driving motor 7 for driving the hair-pulling assembly 3 to rotate is provided in the housing 1;

[0041] A limiting component 5, one end of which is rotatably connected to the inner wall of one end of the curling portion 101, and when the limiting component 5 rotates, the other end of the limiting component 5 can abut against the outer peripheral wall of the heating tube 2;

[0042] like Figure 2 As shown, a cylindrical curling portion 101 is provided in the housing 1, and a trumpet-shaped through-groove 106 is provided axially on the cylindrical wall of the curling portion 101. This enlarges the opening of the through-groove 106, facilitating the transverse passage of hair through the through-groove 106 and directly entering the gap between the curling portion 101 and the heating tube 2. As the hair-moving assembly 3 rotates, the hair is quickly wrapped around the surface of the heating tube 2, which heats and shapes the hair, thereby completing the curling process.

[0043] During the curling process, the hair-moving assembly 3 rotates around the heating tube 2, driving the hair to rotate along with it. If both ends of the hair are not fixed, the hair will rotate around the heating tube 2 along with the hair-moving assembly 3 and cannot be effectively wrapped around the outside of the heating tube 2. Therefore, a limiting assembly 5 is added to limit the hair at one end so that it cannot rotate around the heating tube 2. As a result, only one end of the hair can rotate around the heating tube 2, thereby achieving the effect of the hair being wrapped around the heating tube 2.

[0044] At the same time, the limiting assembly 5 is rotatably mounted on the inner wall of the curling section 101. When the limiting assembly 5 is in a non-operating state, its free end does not abut against the outer peripheral wall of the heating tube 2. Specifically, the free end of the limiting assembly 5 abuts against the limiting groove of the end cover 4 at the front end of the heating tube 2. That is, hair can pass through the gap between the heating tube 2 and the curling section 101 at the position where the limiting assembly 5 is located, thereby avoiding the problem of hair tangling there. After curling is completed, the free end of the limiting assembly 5 disengages from the limiting groove of the end cover 4 at the front end of the heating tube 2, which helps to pull the hair curler out from the end of the heating tube 2, making the use of the automatic curling iron more convenient.

[0045] In some embodiments, as Figure 5 As shown, the housing 1 further includes a handle portion 102, which is fixedly connected to the curling portion 101, and the center line angle between the handle portion 102 and the curling portion 101 is α, 100°≤α≤150°;

[0046] The motor of an existing automatic hair curler is generally located inside the handle, which makes the entire body longer. Furthermore, since the hair curler is usually tilted at a certain angle to the hair when operating the hair, the weight of the hair curler is suspended in the air, causing a noticeable weighty feeling. The force support point of the operator's hand is the wrist, which is particularly noticeable during long-term operation, greatly affecting the operator's operating experience. Therefore, in this embodiment, an angle α is maintained between the handle portion 102 and the hair curling portion 101, wherein the angle α is preferably 105°, 110°, 115°, 120°, 130°, 140°, or 150°. Due to the presence of the angle α, the handle portion 102 does not need to be tilted when the user uses the automatic hair curler. The centerline of the hair curling portion 101 is parallel to the direction of hair growth, and the arc of growth is exactly tangent to the head, greatly reducing the weighty feeling during use. The operator only needs to move the hair curler up and down to create the desired style.

[0047] In some embodiments, as Figure 1 and Figure 6 As shown, a heating switch 104 and a rotary switch 103 are provided in the handle portion 102. The heating switch 104 is electrically connected to the control unit of the heating tube 2, and the rotary switch 103 is electrically connected to the control unit of the drive motor 7.

[0048] When using the hair curler, the heating switch 104 is first turned on to heat the heating tube 2 to a set temperature and maintain the temperature. Then, the hair is placed into the curling part 101 through the through slot 106. Then, the rotation switch 103 is turned on to make the driving motor 7 drive the hair twisting assembly 3 to rotate, thus wrapping the hair around the heating tube 2 and completing the curling.

[0049] The heating switch 104 and the rotary switch 103 are separated to facilitate step-by-step operation.

[0050] In some embodiments, as Figure 3 and Figure 4 As shown, the rotary switch 103 is a push-type switch and has a return spring inside. The rotary switch 103 is connected to the limit assembly 5 through a transmission mechanism. When the rotary switch 103 is pressed, it can drive the limit assembly 5 to rotate so that the free end of the limit assembly 5 abuts against the outer peripheral wall of the heating tube 2.

[0051] like Figure 6 As shown, a rotating shaft is provided in the limiting assembly 5, and a transmission mechanism is provided between the end of the rotating shaft and the rotary switch 103. When the rotary switch 103 is pressed, the limiting assembly 5 is driven to rotate by the transmission mechanism, so that the free end of the limiting assembly 5 abuts against the outer wall of the heating tube 2, thereby limiting the root of the hair and preventing it from rotating with the hair pulling assembly 3; at the same time, when the rotary switch 103 is released, the rotary switch 103 can be quickly reset under the action of the reset spring, and under the action of the transmission mechanism, the limiting assembly 5 is driven to quickly reset, so that the hair curler is easy to be pulled out from the end of the heating tube 2.

[0052] In some embodiments, a Hall element is provided in the housing 1 for monitoring the rotation angle of the hair-pulling assembly 3 , and the Hall element is connected to the control power supply of the driving motor 7 ;

[0053] like Figure 6 As shown, a Hall element is provided in the curling portion 101, and its monitoring module and motion module are fixedly mounted to the curling portion 101 and the hair-pulling component 3, respectively, and can monitor the rotation angle of the hair-pulling component 3. When the rotary switch 103 is triggered, the drive motor 7 drives the hair-pulling component 3 to rotate. When the Hall element detects that the hair-pulling component 3 has rotated to a set number of turns or angle, it sends a signal to the control unit of the drive motor 7, controlling the drive motor 7 to stop rotating.

[0054] In some embodiments, the heating tube 2 includes a heat-conducting sleeve 8 and a heating component 6 , and the heating component 6 is fixedly nested in the heat-conducting sleeve 8 ;

[0055] like Figure 6 As shown, a heat-conducting sleeve 8 is installed on the outside of the heating component 6 to help make the temperature of the outer wall of the heating tube 2 uniform and avoid the problem of hair burning caused by excessive temperature at a single point.

[0056] In some embodiments, a temperature detection unit is further provided in the heating tube 2, and the temperature detection unit is electrically connected to the control unit of the heating tube 2;

[0057] The handle portion 102 is provided with an indicator light 105, which is electrically connected to the temperature detection unit of the heating tube 2;

[0058] By providing a temperature detection unit in the heating tube 2, the temperature of the heating tube 2 is monitored in real time and fed back to the control unit of the heating tube 2 to ensure that the heating tube 2 stops heating or keeps the temperature from rising further after reaching the set temperature. In addition, the indicator light 105 provided on the handle 102 is used to display a signal, so that the user can quickly know whether the current heating tube 2 is in an operational state.

[0059] In some embodiments, the temperature detection unit mainly relies on the control unit of the heating tube 2 to count the power and working time of the heating component 6, and then calculates to obtain the current temperature of the heating component 6 and the heating tube 2, and further adjusts the real-time output power of the heating component 6 according to the calculation results.

[0060] In some embodiments, as Figure 3 and Figure 4 As shown, the end of the heating tube 2 is also fixedly provided with an end cap 4, and the outer peripheral wall of the end cap 4 is provided with a limiting groove; when the limiting component 5 rotates, its free end can be clamped in the limiting groove;

[0061] An end cap 4 is provided at the end of the heating tube 2. The end cap 4 is preferably made of a non-heat-conducting material to prevent the heat in the heating tube 2 from being transferred to the limiting component 5. A limiting groove is added in the end cap 4 for the free end of the limiting component 5 to be clamped, thereby effectively ensuring the stability of the limiting component 5 in the working state.

[0062] In some embodiments, as Figure 6 As shown, the hair pulling assembly 3 includes a sleeve portion and a tooth portion. The sleeve portion is rotatably sleeved on the outside of the heating tube 2. The tooth portion is fixedly connected to the sleeve portion and can rotate around the center line of the sleeve portion. The side of the tooth portion is spiral.

[0063] By setting the side edges of the teeth in a spiral shape, when the hair is wrapped around the outer wall of the heating tube 2, a force is exerted along the axial direction of the heating tube 2, so that the hair can be arranged along the axial direction of the heating tube 2, avoiding radial accumulation, and the hair can be evenly heated by the outer wall of the heating tube 2.

[0064] In some embodiments, the inner wall of the tooth portion is provided with a ridge along the center line of the hair pulling assembly 3, and a gap is provided between the ridge and the outer wall of the heating tube 2;

[0065] By adding ridges to the inner wall of the teeth, the gap between the inner wall of the hair-moving component 3 and the outer wall of the heating tube 2 is further reduced. When the hair-moving component 3 drives the hair to wrap around the surface of the heating tube 2, due to the small gap between the hair-moving component 3 and the heating tube 2, the ridges can generate greater friction with the hair, thereby tightening the hair and then tightly wrapping it around the outer wall of the heating tube 2, ensuring the heating effect of the hair.

[0066] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
