Description

Automatic hair curler Technical Field

[0001] The utility model belongs to the technical field of hairdressing tools, in particular to an automatic hair curler. Background Art

[0002] A curling iron is one of the most commonly used devices in the hairdressing industry. It consists of a heat pipe and a hair roller. When using it, a strand of hair is placed on the hair roller, and then the hair roller is rotated to cause the hair to wrap around the heat pipe, which heats and shapes the hair into a wavy shape.

[0003] The heating element in existing curling irons has a smooth surface and no position to fix the hair. When in use, the hair easily slides on the heating element, affecting the curling effect. In addition, the heating element is the main component that forms the hair into a fixed shape, so it is sufficient to ensure that the heat of the heating element is sufficient. However, the existing curling chamber is narrow, and the heat generated by the heating element will accumulate in the heating chamber and cannot be dissipated, resulting in a very high temperature of the shell. Even when not in use, it takes a long time to cool down. The hair puller and the shell are basically made of plastic, and excessive temperature will easily cause deformation and damage. Utility Model Content

[0004] The purpose of the present utility model is to provide an automatic hair curler to solve the problems raised in the above background technology.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Please refer to Figures 1-7;

[0030] The automatic hair curler of the present invention is provided with a pre-fixed position for hair, so that the hair does not become loose. The hair-pulling member 3 can better drive the hair to rotate, thereby improving the curling effect. In addition, the heat dissipation performance is improved, the heat dissipation speed is accelerated, and burns are avoided. Specifically, it comprises a handle 1, on which is mounted a heat duct 21. The top of the heat duct 21 is provided with an inclined groove 22 for receiving hair. The hair-pulling member 3 connected to the driving device is located on the outer periphery of the heat duct 21. The hair-pulling member 3 is provided with a hair-pulling position 33 corresponding to the inclined groove 22. In the initial state, the hair-pulling position 33 corresponds to the inclined groove 22. In this embodiment, the inclined groove 22 is U-shaped when viewed from the front and top, and has an inverted triangular inclined shape when viewed from the side.

[0031] When in use, take a bunch of hair near the root end and put it into the inclined groove 22. The inclined groove 22 adopts a design of high rear end and low front end to increase the effect of putting the hair bunch in; after the hair bunch extends out of the inclined groove 22, it will enter the hair-pulling position 33. In this embodiment, the hair-pulling member 3 includes a transmission part 31, which is connected to a driving device (not shown in the figure). The transmission part 31 extends vertically upward to form two hair-pulling rods 32. The two hair-pulling rods 32 are close to form a "U"-shaped hair-pulling position 33. That is to say, after the hair bunch extends out of the inclined groove 22 and enters the "U"-shaped hair-pulling position 33, when the driving device drives the transmission part 31 to rotate, the two hair-pulling rods 32 will follow and surround the heat-generating duct 22. 1 rotates, and at the same time, moves the hair bundle so that it is wrapped around the outer periphery of the heating duct 21. Through the mutual cooperation of the "U"-shaped hair-moving position 33 and the inclined groove 22, the inserted hair bundle is sheared and driven to be wound. During this process, the hair bundle is pulled and conflicts with the side wall of the inclined groove 22 and bends laterally. The friction generated by the bending of the hair bundle is used to fix the relative position between the hair bundle and the heating duct 21, and the hair bundle near the root is not entangled therein, and the slippage during use is avoided, thereby ensuring the curling effect. In addition, by pre-arranging the hair and placing it in the inclined groove 22, the hair bundle can be prevented from being scattered and irregularly entangled during the curling process, thereby avoiding harm to the user.

[0032] In addition, in this embodiment, the heat channel 21 and the hair-pulling member 3 form a curling chamber, and a heat dissipation structure is formed at the two hair-pulling rods. The heat dissipation structure avoids heat accumulation and can achieve rapid heat dissipation.

[0033] The heat dissipation structure of the utility model has three implementation modes:

[0034] In the first embodiment, the space outside the two trigger levers 32 is free of components, forming a heat dissipation area 34. The heat dissipation area 34 is hollow and unobstructed, so there is no heat accumulation and rapid heat dissipation can be achieved.

[0035] In the second embodiment, the two hair-moving rods 32 are provided with a plurality of heat dissipation holes 37. During use, the heat in the curling chamber can be dissipated to the outside through the heat dissipation holes 37, thereby achieving rapid heat dissipation.

[0036] In the third embodiment, which is a structure that is a combination of the first and second embodiments, the triggering member 3 is provided with a heat dissipation hole 37 and a heat dissipation position 34 at the same time.

[0037] In the embodiment of the present invention, the upper end of the heat passage 21 is formed into an arc transition 23 along both sides of the inclined groove 22 , which is beneficial for the arrangement of hair bundles and their entry into the inclined groove 22 .

[0038] In the embodiment of the present invention, the upper ends of the two hair-moving rods 32 are connected by a back ring 35, and the heat-generating tube 21 passes through the back ring 35. The back ring 35 is not only conducive to limiting the relative positions of the two hair-moving rods 32 to prevent deformation, but also can block the entrances outside the two hair-moving rods 32 to prevent hair from entering.

[0039] In this embodiment, the position of the hair-pulling member 3 can be limited by a Hall sensor, so that the "U"-shaped hair-pulling position 33 can be aligned with the inclined groove 22 every time it is started; there is also a situation where no Hall sensor is set for alignment, that is, before use, the "U"-shaped hair-pulling position 33 is not necessarily aligned with the inclined groove 22. At this time, a bunch of hair is placed in the inclined groove 22. After the hair extends out of the inclined groove 22, it will be blocked by the back ring 35 and will not enter the inside of the hair-pulling member 3. As the hair-pulling member 3 rotates, the hair will slide on the surface of the back ring 35 to avoid secondary curling and hair entanglement. When the "U"-shaped hair-pulling position 33 is aligned with the inclined groove 22, the hair immediately enters the "U"-shaped hair-pulling position 33, and the hair is wound around the heating duct 21 under the drive of the hair-pulling rod 32.

[0040] Preferably, the back ring 35 is connected to the highest point of the "U"-shaped dialing position 33, and the height of the back ring 35 relative to the "U"-shaped dialing position 33 is lower than the height of the "U"-shaped dialing position 33. As shown in Figure 7, h1 is the height of the highest point of the "U"-shaped dialing position 33, and h2 is the height of the lowest point of the back ring 35. The back ring 35 of the dialing member 3 is formed with a continuously and smoothly changing height, height h1>height h2, and the height gradually and smoothly decreases from h1 to h2, or gradually and smoothly increases from h2 to h1.

[0041] In the embodiment of the present invention, vertically extending ridges 36 are provided on the inner sides of the two hair moving rods 32. The ridges 36 extend into the curling cavity, guiding and blocking the hair, thereby increasing the contact area between the hair moving member 3 and the hair bundle.

[0042] In the embodiment of the present utility model, a protective shell 4 is connected to the handle 1, and the protective shell 4 is located on the outer periphery of the hair-pulling member 3. The protective shell 4 in this embodiment mainly plays a protective role to prevent people from touching the heat-generating passage 21 and getting burned; the protective shell 4 includes an arc-shaped protective plate 41, and the front side of the arc-shaped protective plate 41 is provided with a large opening 42 in the same direction as the inclined groove 22. When the heat dissipation position 34 of the hair-pulling member 3 corresponds to the arc-shaped protective plate 41, the "U"-shaped hair-pulling position 33 corresponds to the large opening 42. When the heat dissipation position 34 corresponds to the large opening 42, the heat dissipation effect is best, so that the temperature of the shell surface will not be too high; the upper end of the large opening 42 is provided with ribs 43 respectively connected to the two sides of the arc-shaped protective plate 41, and a hair-entry position 44 corresponding to the inclined groove 22 is formed between the two ribs 43.

[0043] In this embodiment, the heat vent 21 is at least partially higher than the hair puller 3 and the protective housing 4 to improve the heat dissipation effect. Of course, the heat vent 21 is not much higher to avoid the risk of touching it. The height difference between the lowest point of the protective housing 4 and the heat vent 21 is h3, as shown in Figure 6, and h3 is less than or equal to 5CM.

[0044] In this embodiment, a plurality of heat dissipation holes 45 are provided on the arc-shaped protection plate 41 . The cooperation between the plurality of heat dissipation holes 37 and the plurality of heat dissipation holes 45 can enhance the heat dissipation effect.

[0045] It should be noted that the heat dissipation position 34 of the hair-pulling member 3 is equivalent to a special case of the heat dissipation hole 1 37, that is, the heat dissipation position 34 is a heat dissipation hole 1 37 with a larger aperture, and the heat dissipation position 34 and the heat dissipation hole 1 37 both play the same heat dissipation function; the hair entry position 44 of the protective shell 4 only plays the function of avoiding and making way, that is, it does not participate in the function of plucking the hair, and the large opening 42 of the protective shell 4 is equivalent to a special case of the heat dissipation hole 2 45, that is, the large opening 42 is a heat dissipation hole 2 45 with a larger aperture and connected to the hair entry position 44, and the large opening 42 and the heat dissipation hole 2 45 both play the same heat dissipation function, and the large opening 42 can be replaced by multiple heat dissipation holes 2 45 with relatively smaller apertures. The replaced structure is safer and the user can avoid getting burned by accidentally inserting his fingers into it.

[0046] In summary, the heat dissipation position 34, heat dissipation hole 1 37, and hair-pushing position 33 of the hair-pushing member 3, and the large opening 42, heat dissipation hole 2 45, and hair-entry position 44 of the protective shell 4, maintain holes in the inner and outer layers connected to the outside, which is conducive to the rapid dissipation of heat generated by the heat passage 21, reducing the surface temperature of the protective shell 4, and improving the user's comfort experience.
