Description

Technical Field

[0001] The utility model relates to a hair curler for curling and curling hair, in particular to a hair curler with a negative ion generator capable of spraying negative ions. Background Art

[0002] The hair curler generally comprises a handle for the user to grasp, a hair curler assembly having a hair curler capable of heating, a rotating drum rotatably arranged around the hair curler of the hair curler assembly and having a longitudinal opening, a pressing plate arranged on the inner wall of the rotating drum and used to press the hair against the hair curler, and a housing arranged around the rotating drum. The temperature of the hair curler capable of heating the hair curler of the hair curler assembly can be regulated by an electric control device. The hair curler of the hair curler assembly is generally made of heat-conducting materials such as copper, aluminum or titanium alloy and coated with a coating such as tourmaline or ceramic on the surface so that the hair curler is heated evenly, thereby creating a bend and protecting the hair quality by improving the protein structure of the hair during the hair curling process. When using the hair curler, the user can put the hair into the rotating drum from the top edge of the rotating drum close to the hair curler through the longitudinal opening, and the pressing plate presses the hair against the hair curler so that the hair rotates around the hair curler, thereby winding the hair around the heated hair curler to curl the hair and form a curved shape.

[0003] Some hair curlers are also equipped with negative ion generators to release negative ions toward the hair during the curling process. When the hair comes into contact with the negative ions, the negative ions help neutralize the positive charge in the hair, thereby reducing frizz, increasing luster, and improving the overall health of the hair. In existing hair curlers, the negative ion generator and the negative ion diffusion window are set at the junction of the handle and the shell around the drum. Unlike hair dryers that process a large amount of hair, hair curlers can only curl a small amount of hair at a time. The negative ion diffusion window is set at the junction of the handle and the shell around the drum, making it difficult for the negative ions to effectively diffuse to the hair being curled.

[0004] Therefore, it is necessary to improve the existing hair curling iron with negative ion generator. Utility Model Content

[0035] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the accompanying drawings are only used to illustrate the present invention and do not constitute a limitation to the present invention.

[0036] Figure 1 The hair curler according to the present invention is schematically shown in a three-dimensional diagram. Figure 2 yes Figure 1 A three-dimensional view of the curling iron from another direction, Figure 3 yes Figure 1 A perspective view of the hair curler from another direction, wherein the housing disposed around the drum is partially cut away, and Figure 4 yes Figure 3 A partial enlarged view of Figure 1-4 As shown, the hair curler 1 according to the present invention comprises a handle 3 for a user to grasp, a hair curler assembly 7 connected to the handle 3 and having a hair curler 5 capable of generating heat, a rotating drum 11 rotatably arranged around the hair curler 5 of the hair curler assembly 7 and having a longitudinal opening 9, a pressing plate 13 arranged on the inner wall of the rotating drum 11 and used to press the hair against the hair curler 5, and a housing 15 arranged around the rotating drum 11. It should be understood that in the present application, the connection between the hair curler assembly 7 and the handle 3 includes a situation where the two are directly connected, and also includes a situation where the two are indirectly connected through other elements. Of course, the hair curler 1 according to the present invention also includes an electric control device and a motor arranged in the handle 3, and a transmission mechanism (such as a gear) arranged inside the housing 15 and used to transmit the rotational motion of the motor to the rotating drum 11.

[0037] The housing 15 of the hair curler 1 according to the utility model includes a first U-shaped groove 17, and the first U-shaped groove 17 has a large depth, which can roughly correspond to the longitudinal length of the hair curler 5 of the hair curler assembly 7. Of course, the housing 15 can also include a second U-shaped groove 19 which is arranged radially opposite to the first U-shaped groove 17 and has a relatively small depth. The second U-shaped groove 19 can help the user put the hair into the rotating drum for winding. When in use, the user can put the hair from the top edge of the rotating drum 11 to the hair curler 5 downward by means of the second U-shaped groove 19 and the longitudinal opening 9 of the rotating drum 11, and the pressing plate 13 presses the hair against the hair curler 5. When the hair curler is turned on, the pinion on the output shaft of the motor drives the gear of the transmission mechanism to rotate, and then drives the rotating drum 11 installed on the gear of the transmission mechanism to rotate around the hair curler 5, so that the hair is wound around the heated hair curler 5 to curl the hair and form a curved shape.

[0038] The curling iron 1 further comprises a negative ion generator, which comprises a negative ion generating device provided in the handle 3 and having a negative ion generating circuit, etc., and a negative ion output sheet 21 electrically connected to the negative ion generating device via a wire. Of course, the negative ion generator comprises a grounding sheet (not shown in the figure) electrically connected to the negative ion generating device via a wire.

[0039] In the hair curler 1 according to the present invention, the negative ion diffusion window 23 through which the negative ions released by the negative ion output sheet 21 diffuse is provided on the bottom wall of the first U-shaped groove 17. In a preferred embodiment, the bottom wall 17a of the first U-shaped groove 17 is formed as an inclined wall so that the negative ion diffusion window 23 has an enlarged opening area. Figure 5 The schematic diagram shows the influence of the negative ion diffusion window formed when the bottom wall of the first U-shaped groove is flat or inclined on the diffusion of negative ions. Figure 5 (a) shows the case where the negative ion diffusion window 23 has a straight opening relative to the horizontal direction when the bottom wall 17a of the first U-shaped groove 17 is flat. In this case, the negative ion diffusion window 23 has a relatively small opening area, the diffusion area of ​​the negative air ions is small, and thus the contact area between the negative air ions and the hair H is also small, and the adsorption rate of the hair to the negative air ions is relatively low. Figure 5 (b) shows the case where the negative ion diffusion window 23 has an opening that is inclined relative to the horizontal direction when the bottom wall 17a of the first U-shaped groove 17 is inclined. In this case, the negative ion diffusion window 23 has a relatively large opening area, the diffusion area of ​​the negative air ions becomes larger, and thus the contact area between the negative air ions and the hair H is also increased, and the adsorption rate of the negative air ions by the hair is relatively high. In this way, by forming the bottom wall 17a of the first U-shaped groove 17 as an inclined wall, the effective diffusion area of ​​the negative ion diffusion window 23 can be increased while the width of the bottom wall of the first U-shaped groove 17 (i.e., the housing 15) remains unchanged, so as to facilitate the diffusion of negative air ions to the hair and facilitate the adsorption of negative air ions by the hair. In a preferred embodiment, the inclination angle α of the bottom wall 17a of the first U-shaped groove 17 relative to the horizontal direction is in the range of 30-60°. More preferably, the bottom wall of the first U-shaped groove 17 gradually inclines downward from the inside to the outside of the housing.

[0040] In the existing curling iron, since the junction of the handle and the shell around the rotating drum is usually designed to be circular, its size is highly optimized, the design is very compact, and the available space is very limited. Placing the negative ion generator and the negative ion diffusion window at the junction of the handle and the shell around the rotating drum will inevitably significantly increase the size of the junction. Different from this, the utility model is provided by separately arranging the negative ion output sheet and the negative ion generating device, more preferably, the negative ion output sheet is arranged in the shell and the negative ion generating device is arranged in the handle. In this way, the size of the junction of the handle and the shell around the rotating drum will not be increased, so that the curling iron can have a highly optimized compact structure and size.

[0041] Since the negative ion diffusion window 23 is disposed on the bottom wall 17 a of the first U-shaped groove 17 , the negative ion output sheet 21 for releasing negative ions can be disposed in the housing 15 adjacent to the negative ion diffusion window 23 . Figure 6The output sheet of the negative ion generator is schematically shown in a three-dimensional diagram. Figure 6 As shown, the negative ion output sheet 21 is in the shape of a sheet and has at least one release tip 21a. Although having more release tips 21a can help release negative air ions, considering the arrangement of the negative ion output sheet 21 in the housing 15 and the overall shape and size of the curling iron, the negative ion output sheet 21 preferably has two release tips 21a spaced apart to form a generally U-shaped shape. For example, the negative ion output sheet 21 can be fixed to the inside of the housing 15 by means of screws passing through the holes 22 on the negative ion output sheet 21, and the release tip 21a of the negative ion output sheet 21 is exposed from the negative ion diffusion window 23. It should be noted that, in order to facilitate the manufacture of the curling iron and the installation of the corresponding components, the housing 15 can be composed of an inner housing and an outer housing. In order to prevent dust or foreign matter from entering the interior of the housing 15 through the negative ion diffusion window 23, a screw such as the following can be provided in the negative ion diffusion window 23. Figure 7 The cover member 25 shown in FIG. 2 includes a main body 25b with two through holes 25a, and hooks 25c formed on both sides of the main body 25b. Figure 7 Only the hook on the left side is visible, and the hook on the right side is blocked and invisible. The top surface of the main body 25b of the cover member 25 can be inclined or flat, but when the cover member 25 is inserted in the negative ion diffusion window 23 and is connected with the housing 15 by the hook 25c and is fixed in the negative ion diffusion window 23, the setting of the negative ion diffusion window 23 tilted relative to the horizontal direction can not be affected, and the release tip 21a of the negative ion output sheet 21 is exposed to communicate with the external air by the through hole 25a. Although in the preferred embodiment shown, the cover member 25 is shown as being removably arranged in the negative ion diffusion window 23, it is understandable that it is also feasible that the cover member 25 is formed integrally with the housing 15.

[0042] According to the utility model, the negative ion diffusion window through which the negative ions released by the negative ion output sheet diffuse is arranged on the bottom wall of the first U-shaped groove. The negative ions diffused through the negative ion diffusion window are closer to the hair being curled and can be easily diffused to the hair being curled, thereby improving the hair's adsorption efficiency for negative air ions, helping to neutralize the positive charge in the hair, so as to reduce the frizziness of the hair, increase the luster of the hair, and improve the overall health of the hair.

[0043] Although the present invention has been described in detail in conjunction with the preferred embodiments of the present invention, it should be understood that such detailed description is only used to explain the present invention and does not constitute a limitation on the present invention. The scope of the present invention is determined by the technical solutions defined in the claims.
