[0027] To clearly illustrate the solutions in this invention, preferred embodiments are given below in conjunction with the accompanying drawings. The following description is merely exemplary and not intended to limit the application or use of this disclosure. It should be understood that throughout the drawings, corresponding reference numerals denote the same or corresponding parts and features.
[0028] See Figures 1 to 12This invention provides a novel automatic curling iron, comprising a housing 1, a hair-winding drum 2 located within the housing 1, and a curling iron 3 located within the hair-winding drum 2. A curling cavity is formed between the hair-winding drum 2 and the curling iron 3. The housing 1 is provided with a negative pressure suction channel 4 and a styling blow-drying channel 5. The negative pressure suction channel 4 is connected to the top hair guide section 31 of the curling iron 3. A styling air chamber 12 is provided within the housing 1, and the styling blow-drying channel 5 is connected to the styling air chamber 12. The negative pressure suction channel 4 in this invention creates negative pressure in the hair guide section 31, automatically guiding external hair into the curling cavity and preventing hair from falling out during the curling styling process. After the curling styling is completed, the styling blow-drying channel 5 applies cool air to set the styled hair. Therefore, this invention has negative pressure guidance, curling styling, and cool air setting functions, resulting in better curling effects. In this invention, the housing 1 is a large housing structure that completely encloses the hair-winding drum 2, with a handle formed at the bottom. The curling iron 3 is used to wind and heat the hair to create curls. The curling iron 3 is equipped with a heating element. The hair-winding drum 2 can rotate, guiding the introduced hair around the curling iron 3. Traditional curling irons require the user to manually guide the hair onto the curling iron 3, which is then wound by the hair-winding drum 2. Due to static electricity and other reasons, the hair is sometimes difficult to guide, or the guidance effect is not ideal, resulting in poor curling effect or even hair damage. This invention uses negative pressure suction to guide the hair, making it easier to guide the hair onto the guide section 31 of the curling iron 3, resulting in a better curling effect.
[0029] See Figures 1 to 12 In the above embodiments provided by the present invention, the hair guiding part 31 further includes two vertical winglets 311 and a guide panel 312. The guide panel 312 is inclined to facilitate hair guidance. The two winglets 311 are arranged opposite each other, forming a groove between them. The winglets 311 are used to gather the hair, causing the hair to be bundled and adhered to the guide panel 312. The guide panel 312 is provided with a suction hole 313, and the negative pressure suction channel 4 communicates with the suction hole 313. The above structure makes the space formed between the winglets 311 form a negative pressure cavity, which makes it easy for external hair to be sucked into the negative pressure cavity and finally adhered to the guide panel 312. The hair will not fall out when it is rolled up. A filter screen is also provided at the suction hole 313 to prevent hair from being sucked into the negative pressure suction channel 4.
[0030] See Figures 1 to 12In the above embodiments provided by the present invention, a high-speed fan 6 is further included in the housing 1. The high-speed fan 6 has two working modes: suction and blowing. In suction mode, the high-speed fan 6 is connected to the negative pressure suction channel 4; in blowing mode, the high-speed fan 6 is connected to the shaping blowing channel 5. The high-speed fan 6 of the present invention forms a suction mode when rotating in reverse and a blowing mode when rotating in the forward direction. By controlling the forward and reverse rotation of the high-speed fan 6, both suction and blowing are achieved, making operation more convenient.
[0031] See Figures 1 to 12 In the above embodiments provided by the present invention, a suction one-way valve 41 is provided at the air outlet 45 of the negative pressure suction channel 4, and a blower one-way valve 51 is provided at the blower hole 52 of the styling blower channel 5. The present invention has two one-way valve structures. In suction mode, the suction one-way valve 41 is open, and the blower one-way valve 51 is closed, so that the negative pressure suction channel 4 is connected to the hair guide part 31 to form a negative pressure chamber. In blower mode, the suction one-way valve 41 is closed, and the blower one-way valve 51 is open, so that the styling blower channel 5 is connected to the styling air chamber 12, blowing out styling cool air. The styling air chamber 12 in the present invention is formed by the cavity between the housing 1 and the hair-winding drum 2. After the styling air enters the styling air chamber 12, it is blown onto the hair wrapped around the curling iron 3 through the notch on the hair-winding drum 2, styling the hair and facilitating hair styling. Of course, the styling air cavity 12 can also be formed by the space between the hair-winding cylinder 2 and the curling iron 3, and the styling air is directly blown into the styling air cavity 12 to style the hair wrapped around the curling iron 3.
[0032] See Figures 1 to 12 In the above embodiments provided by the present invention, the suction one-way valve 41 further includes a valve frame 42 and an umbrella-shaped valve 43 mounted on the valve frame 42. The valve frame 42 is provided with a vent hole 44, and the umbrella-shaped valve 43 covers the vent hole 44. The valve frame 42 is installed at the air outlet 45 of the negative pressure suction channel, and the umbrella-shaped valve 43 is used to control the opening and closing of the air outlet 45.
[0033] See Figures 1 to 12 In the above embodiments provided by the present invention, the umbrella-shaped air valve 43 is made of silicone material, the middle part of the umbrella-shaped air valve 43 is connected to the air valve frame 42, and the edge of the umbrella-shaped air valve 43 is bent and deformed by wind pressure. In the suction mode, the suction airflow pushes the edge of the umbrella-shaped air valve 43 to deform, thereby opening the vent.
[0034] See Figures 1 to 12In the above embodiments provided by the present invention, the umbrella-shaped air valve 43 has a central thickness of A1 and an edge thickness of A2, where A1 = K * A2, and K is a proportionality coefficient ranging from 2 to 4. In this embodiment, K is set to 3, resulting in a better proportional relationship between the umbrella-shaped air valve 43 and the one-way valve, which can automatically operate during the suction and blowing processes, thus improving the effect.
[0035] See Figures 1 to 12 In the above embodiments provided by the present invention, the blower valve 51 is further comprising a silicone air valve, the middle part of which is connected to the shaping blower channel 5, and the edge of which covers the blower hole 52. The edge of the silicone air valve is bent and deformed by wind pressure. During the blowing process, the airflow can push the edge of the silicone air valve, thereby opening the blower hole 52 and connecting the shaping blower channel 5 with the shaping air chamber 12.
[0036] See Figures 1 to 12 In the above embodiments provided by the present invention, a negative pressure air guide flat barrel 7 is further included. The negative pressure air guide flat barrel 7 is inserted into the inner cavity of the curling iron body 3. The negative pressure air guide flat barrel 7 includes an air intake heating channel 71 and an air intake rectification channel 72. The air intake heating channel 71 is connected to the air intake rectification channel 72, and the air intake rectification channel 72 is connected to the negative pressure air intake channel 4. The air intake heating channel 71 is connected to the guide panel 312. The air intake rectification channel 72 rectifies and cools the hot air intake airflow, allowing the low-temperature airflow to enter the high-speed fan. The curling iron body 3 of the present invention is equipped with a heating component. Therefore, the airflow drawn in from the guide panel 312 will be heated. If the hot air directly enters the high-speed fan, it will affect the heat dissipation of the high-speed fan. The present invention provides a negative pressure air guide flat barrel 7, which can isolate the heated airflow and simultaneously rectify and cool the heated airflow, reducing the temperature of the airflow entering the high-speed fan.
[0037] See Figures 1 to 12 In the above embodiments provided by the present invention, the housing 1 is further provided with a hair guide groove 11. The hair guide groove 11 guides hair into the housing, and the housing 1 facilitates the formation of a negative pressure chamber.
[0038] See Figures 1 to 12 In the above embodiments provided by the present invention, a plurality of hair-winding forks 21 are formed on the hair-winding drum 2, and the hair-winding drum 2 is driven to rotate by a motor 22. The hair-winding forks 21 are used to wind the hair so that the hair can be wrapped around the curling iron 3.
[0039] In summary, the above descriptions are merely embodiments of the present invention and are used only to illustrate the principles of the invention, not to limit the scope of protection of the invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
