A curling system

Abstract

This invention proposes a hair curling system. A curling tube and an air duct are connected via a pipe connector. The air duct is supplied with hot airflow from an air source. During curling, hair is simply wound around a spiral hair-winding groove. The air duct delivers hot airflow to the tube body via the pipe connector. The hot airflow enters through the air inlet of the tube body and is directly delivered to the hair-winding groove outlet and the convex wall outlet via the ventilation duct of the tube body. Simultaneously, hot airflow is blown onto the hair within the spiral hair-winding groove from both the hair-winding groove outlet and the convex wall outlet. Due to the depth of the spiral hair-winding groove, the hair-winding groove outlet and the convex wall outlet can deliver a three-dimensional jet of hot airflow onto the hair, enabling uniform heat styling. Furthermore, the spiral hair-winding groove can orderly and regularly limit and shape the wound hair. This invention offers advantages such as non-destructive, orderly, and efficient curling, uniform styling, and convenience.

Description

Technical Field

[0001] This invention relates to the field of daily life, and more specifically to a hair curling system. Background Technology

[0002] As people's living standards improve, hair styling is receiving more and more attention, and there are many types of hair styling devices used. Curling is a styling option that is frequently used when styling hair. Currently, the curling tools on the market are generally hair dryers with curling combs, or manual curling irons / sticks with clamps.

[0003] For example, Chinese invention patent CN202510705780.8 discloses a hair curler, including a handle, a heating part disposed at the front end of the handle, and a heat-conducting clip hinged to the side wall of the front end of the handle; the heat-conducting clip is parallel to the heating part; the heat-conducting clip is provided with a first electric heating element; when the heat-conducting clip is closed, the inner and outer side walls of the heat-conducting clip respectively form two heating positions for heating the hair. The first electric heating element is embedded inside the heat-conducting clip, and the thickness of the heat-conducting clip is less than or equal to 5mm. The first electric heating element is any one of a heating film, a ceramic heating element, a PTC heating element, or a thick film heating element. The side wall of the heat-conducting clip opposite to the heating part has a mounting groove, and the first electric heating element is disposed in the mounting groove. The heat-conducting clip is also provided with a clamping fixing member to fix the first electric heating element in the mounting groove. The heat-conducting clip is arc-shaped, and the curvature of its concave surface matches the curvature of the side wall of the heating element. The concave surface of the heat-conducting clip and / or the outer side wall of the heating element have a friction-reducing layer. The clamping fastener seals the first electric heating element within the mounting groove and presses it against the bottom surface of the mounting groove. The rear end of the heat-conducting clip has a pressing extension for easy pressing and opening by the user. The handle is provided with an elastic reset member that provides elastic restoring force to the pressing extension. When the heat-conducting clip is closed, the elastic reset member presses outward against the end of the pressing extension away from the pivot of the heat-conducting clip.

[0004] This invention patent is roughly the same in structure and principle as other curling irons on the market. When curling hair, the user directly heats the hair with the heating element and then shapes it through irregular curls. However, because the hair wrapped around the curls has a certain thickness, the hair in contact with and not in contact with the heating element is heated unevenly, resulting in an uneven hairstyle. Moreover, this method of heat contact with the heating element can damage the hair, especially when the temperature of the heating element is too high, which can cause serious damage to the hair. In addition, the curled style is irregular, which is not very operable or aesthetically pleasing. The convenience and practicality need to be improved.

[0005] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Summary of the Invention

[0006] The purpose of this invention is to provide a hair curling system that is non-destructive, orderly, efficient, produces uniform curls, and is convenient and practical.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A hair curling system includes a curling barrel, an air duct for supplying air to the curling barrel, and a connector connecting the curling barrel and the air duct. The curling barrel has an air inlet end connected to the connector and a tip end facing the other end. The curling barrel includes a barrel body, a spiral hair-winding groove formed on the barrel body, and a spiral convex wall disposed on the barrel body and forming the spiral hair-winding groove. The spiral hair-winding groove is a spiral groove formed on the barrel body, and the spiral convex wall is a spiral protrusion disposed on the barrel body. The spiral hair-winding groove forms a hair groove air outlet, and the spiral convex wall forms a convex wall air outlet. The barrel body has a ventilation channel communicating with the hair groove air outlet and the convex wall air outlet. The spiral convex wall forms a convex wall cavity communicating with the convex wall air outlet and the ventilation channel.

[0008] The convex wall air outlet faces the spiral winding groove.

[0009] The spiral convex wall has a first wall side facing the air inlet end of the cylinder and a second wall side facing the tip of the cylinder, and at least one of the first wall side and the second wall side forms a convex wall air outlet.

[0010] The convex-walled cavity is a spiral shape extending along the spiral convex wall.

[0011] The spiral winding groove gradually widens from the bottom to the opening, while the cross-section of the spiral convex wall gradually narrows from the root to the end.

[0012] The spiral convex wall includes a first sidewall on one side of the convex wall cavity and a second sidewall on the other side of the convex wall cavity. The first sidewall faces the air inlet end of the cylinder, and the second sidewall faces the tip of the cylinder. The first sidewall gradually slopes towards the second sidewall from the root to the end of the spiral convex wall, and the second sidewall gradually slopes towards the first sidewall from the root to the end of the spiral convex wall.

[0013] The convex wall air outlet is an opening formed on at least one of the first side wall and the second side wall.

[0014] The convex wall air outlet has an air outlet bottom edge that is closer to the bottom of the spiral winding groove and an air outlet top edge that is farther away from the bottom of the spiral winding groove. The air outlet top edge forms a guide bend that directs the hot airflow to the spiral winding groove.

[0015] The air outlet on the convex wall gradually decreases in size from the inside to the outside.

[0016] The inner wall of the ventilation duct has a guide partition that extends along the convex wall cavity.

[0017] The convex wall cavity is located between two air-guiding partitions.

[0018] The air guide partition gradually narrows from the root to the end.

[0019] The main body of the cylinder gradually tapers from the air inlet end to the tip.

[0020] The air outlets on the convex wall and the air outlets in the groove face the same spiral direction.

[0021] A hair curler consists of two matching, snap-fitting sections that form the body of the curler.

[0022] The spiral winding grooves of the two cylindrical lobes match and correspond to form a complete spiral winding groove, and the spiral convex walls of the two cylindrical lobes match and correspond to form a complete spiral convex wall.

[0023] The air inlet end of the cylinder has an air inlet that communicates with the ventilation duct and a cylinder connection part that connects with the pipe joint.

[0024] The air inlet is circular.

[0025] The cylindrical connection part is a threaded connection part that is connected to the pipe fitting by threads.

[0026] The pipe fitting has a first joint connection part that mates with the cylinder connection part, and a second joint connection part that mates with the air duct.

[0027] The first connector is a threaded connection part that engages with the cylinder connector part via a threaded connection.

[0028] The second connector is a threaded connection part that is connected to the air duct via a thread.

[0029] The air duct has a pipe connection part that mates with the second joint connection part.

[0030] The pipe connection part is a clamping ring that is tightly connected to the second connector connection part, and the clamping ring has an internal thread that mates with the second connector connection part.

[0031] The air duct has a clamping connection part that is tightly fitted to the air source outlet nozzle.

[0032] The clamping connection is a Velcro strap that is attached to the air duct and has tensile elasticity.

[0033] The air duct is a flexible hose.

[0034] A pipe fitting includes a pipe body and a holding part located outside the pipe body.

[0035] There is a thermal insulation gap between the holding part and the main body of the tube.

[0036] The holding part and the main body of the tube are connected by a support connection part.

[0037] By adopting the above technical solution, the hair curling system of the present invention breaks through the traditional structure of hair curlers. In actual use, the curling tube and the air duct are connected and circulated through the pipe joint. The air duct is supplied with hot airflow by the air source. During the curling operation, hair is simply wrapped around the spiral hair-winding groove. The air duct delivers the hot airflow to the tube body through the pipe joint. The hot airflow enters from the air inlet of the tube body and is directly delivered to the hair groove air outlet and the convex wall air outlet through the ventilation duct of the tube body. Hot airflow is blown onto the hair in the spiral hair-winding groove from the hair groove air outlet and the convex wall air outlet of the spiral convex wall at the same time. Since the spiral hair-winding groove has a certain depth, the hair groove air outlet and the convex wall air outlet can spray hot airflow three-dimensionally onto the hair, and can perform uniform heat styling operation on the hair in the spiral hair-winding groove. Moreover, the spiral hair-winding groove can orderly and regularly limit and shape the wrapped hair. Compared with existing technologies, the hair curling system of the present invention has the advantages of non-destructive, orderly and efficient hair curling, uniform styling, and convenience.

Detailed Implementation

[0040] To further explain the technical solution of the present invention, a detailed description is provided below through specific embodiments.

[0041] A hair curling system of the present invention, such as Figures 1-5As shown, the device includes a hair curler 1, an air duct 2 for supplying air to the hair curler 1, and a pipe connector 3 connecting the hair curler 1 and the air duct 2. The hair curler 1 has an air inlet end connected to the pipe connector 3 and a tip end facing the other end. The hair curler 1 includes a body 11, a spiral hair-winding groove 12 formed on the body 11, and a spiral convex wall 13 provided on the body 11 and forming the spiral hair-winding groove 12. The spiral hair-winding groove 12 is a spiral groove formed on the body 11, and the spiral convex wall 13 is a spiral convex protrusion provided on the body 11. The spiral hair-winding groove 12 forms a hair groove air outlet 121, and the spiral convex wall 13 forms a convex wall air outlet 131. The body 11 has a ventilation channel 14 communicating with the hair groove air outlet 121 and the convex wall air outlet 131. The spiral convex wall 13 forms a convex wall cavity 132 communicating with the convex wall air outlet 131 and the ventilation channel 14. In practical use, the hair curling tube 1 and the air duct 2 are connected via a pipe connector 3. The air duct 2 is supplied with hot air and other airflow by the air source 4. During the curling operation, hair is simply wrapped around the spiral hair-winding groove 12. The air duct 2 delivers the hot airflow to the tube body 11 via the pipe connector 3. The hot airflow enters from the air inlet 15 of the tube body 11. The hot airflow and other airflow are directly delivered to the hair groove outlet 121 via the ventilation duct 14 of the tube body 11 and to the convex wall outlet via the convex wall cavity 132. Air vent 131 blows hot airflow onto the hair in the spiral hair-wrapping groove 12 from both the hair groove outlet 121 and the convex wall outlet 131. Because the spiral hair-wrapping groove 12 has a certain depth, the hair groove outlet 121 and the convex wall outlet 131 can spray hot airflow onto the hair in a three-dimensional manner, allowing for uniform heat styling of the hair in the spiral hair-wrapping groove 12. Furthermore, the spiral hair-wrapping groove 12 can orderly and regularly limit and shape the wrapped hair. To ensure that the hot airflow from the convex wall outlet 131 and the hot airflow from the hair groove outlet 121 creates a three-dimensional, uniform heating effect on the hair, the specific structure can be such that the convex wall outlet 131 faces the spiral hair-wrapping groove 12. Furthermore, the spiral convex wall 13 has a first side wall facing the air inlet end of the tube and a second side wall facing the tip of the tube. At least one of the first side wall and the second side wall forms a convex wall air outlet 131, ensuring that the convex wall air outlet 131 faces the spiral hair winding groove 12. To facilitate winding hair, the tube body 11 gradually tapers from the air inlet end to the tip of the tube. This structure also allows the forming spiral curl of the hair to gradually diverge from top to bottom, ensuring an aesthetically pleasing effect. Specifically, the convex wall air outlet 131 and the hair groove air outlet 121 face the same spiral direction. This structure utilizes the Coanda effect to allow the hot airflow from the convex wall air outlet 131 and the hair groove air outlet 121 to flow along the spiral hair winding groove 12 in the same spiral direction, which can automatically drive hair into the spiral hair winding groove 12 and make the hair gathered and neatly arranged. Specifically, the air source 4 and the air supply power device can be separately provided to ensure that the hair curling tube 1 is lightweight and comfortable to use.The specific structure can be such that the curling tube 1 and the air duct 2 are connected and circulated through a pipe connector 3. For ease of user movement, the air duct 2 is a flexible hose, specifically a corrugated plastic hose, ensuring lightweight and maneuverability. The specific structure can also include an air inlet 15 at the air inlet end that communicates with the ventilation duct 14, and a tube connecting part 16 that connects to the pipe connector 3. To facilitate alignment between the air inlet 15 and the pipe connector 3, the air inlet 15 is specifically circular. The tube connecting part 16 is a threaded connection part that connects to the pipe connector 3 via threads. Specifically, the pipe connector 3 has a first connector connecting part 31 that mates with the tube connecting part 16, and a second connector connecting part 32 that connects to the air duct 2. The first connector connecting part 31 is a threaded connection part that mates with the tube connecting part 16 via threads. The second connector connecting part 32 is a threaded connection part that connects to the air duct 2 via threads. Each threaded connection part has mating internal and external threads. To connect the air duct 2 and the pipe connector 3, the air duct 2 has a pipe connector 21 that mates with the second connector connector 32. The pipe connector 21 is a clamping ring that is tightly fitted to the second connector connector 32. The clamping ring has an internal thread that mates with the second connector connector 32, while the threaded connection of the second connector connector 32 has an external thread. The clamping ring can clamp the air duct 2 between the clamping ring and the second connector connector 32 and securely position it. The air source 4 can specifically be a blower, which has an air outlet 41. The air outlet 41 may have an annular groove 412 or a retaining ring 411. The air duct 2 has a clamping connector 22 that is tightly fitted to the air outlet 41 of the air source 4. The clamping connection 22 is a Velcro strap with elasticity that connects to the air duct 2. After the air duct 2 is fitted onto the air outlet 41, the clamping connection 22 can be used to secure the air duct 2 to the air outlet 41 for positioning and connection. Specifically, it can be tightened and locked into the retaining ring 411 or locked into the annular retaining groove 412 to prevent it from falling off. The Velcro strap is elastic and provides a friendly and gentle force, ensuring a secure and positioning connection between the air duct 2 and the air outlet 41, while also providing force-adaptive protection for the air outlet 41 and the air duct 2. To facilitate holding the curling iron 1, the tube connector 3 includes a tube body 33 and a holding part 34 located outside the tube body 33. There is a thermal insulation gap 35 between the holding part 34 and the tube body 33. The thermal insulation gap 35 can isolate the temperature of the airflow passing through the tube body 33, preventing burns or other uncomfortable temperature sensations and ensuring product comfort. The holding part 34 and the tube body 33 are connected by the support connection part 36. This structure ensures the strength of the support holding part 34 and ensures the stability and effectiveness of the thermal insulation gap 35.

[0042] A preferred specific structure is that the convex wall cavity 132 is a spiral extending along the spiral convex wall 13. This allows the hot airflow entering the convex wall cavity 132 through the ventilation duct 14 to rotate and flow along the spiral space. The airflow is stable, and the centrifugal force can, to some extent, increase the speed of the hot airflow ejected from the convex wall outlet 131. To facilitate the winding and regular positioning of hair, the spiral hair-winding groove 12 gradually widens from the bottom to the opening, and the cross-section of the spiral convex wall 13 gradually narrows from the root to the end. Specifically, the spiral convex wall 13 includes a first sidewall 133 on one side of the convex wall cavity 132 and a second sidewall 134 on the other side of the convex wall cavity 132. The first sidewall 133 faces the air inlet end of the cylinder, and the second sidewall 134 faces the tip of the cylinder. The first sidewall 133 gradually slopes towards the second sidewall 134 from the root to the end of the spiral convex wall 13, and the second sidewall 134 gradually slopes towards the first sidewall 133 from the root to the end of the spiral convex wall 13. To ensure that the hot airflow ejected from the convex wall air outlet 131 directly corresponds to the hair in the spiral hair-wrapping groove 12, the convex wall air outlet 131 is an opening formed on at least one of the first side wall 133 and the second side wall 134. This structure allows the convex wall air outlet 131 and the hair-wrapping groove air outlet 121 to cooperate to form a direct and three-dimensional jet of hot airflow. In particular, when both the first side wall 133 and the second side wall 134 have convex wall air outlets 131, hot airflow can be jetted from both sides of the spiral hair-wrapping groove 12 in an all-round three-dimensional manner, ensuring uniform heating of the hair. To ensure the smooth flow of hot air from the ventilation duct 14 and the convex wall cavity 132 towards the spiral winding groove 12, the specific structure can be such that the convex wall outlet 131 has a bottom edge 1312 closer to the bottom of the spiral winding groove 12 and a top edge 1311 farther from the bottom of the spiral winding groove 12. The top edge 1311 forms a guide bend 13111 that directs the hot airflow towards the spiral winding groove 12. The convex wall outlet 131 gradually decreases in size from the inside to the outside. This structure ensures that the hot airflow is accelerated from the convex wall outlet 131 towards the spiral winding groove 12.

[0043] A preferred specific structure may be that the inner wall of the ventilation duct 14 forms an air guide partition 141 extending along the convex wall cavity 132. The air guide partition 141 extends along the edge of the convex wall cavity 132 and protrudes towards the center of the ventilation duct 14. The air guide partition 141 can smoothly guide the hot airflow in the ventilation duct 14 into the convex wall cavity 132, while also confining the hot airflow within the convex wall cavity 132 and allowing it to flow smoothly along the convex wall cavity 132, and then smoothly and stably ejected from the convex wall outlet 131. To ensure the confinement effect of the convex wall cavity 132 on the hot airflow, the convex wall cavity 132 is located between two air guide partitions 141. The air guide partition 141 gradually narrows from the root to the end. This structure can uniformly cut 13110 the hot airflow in the ventilation duct 14 and guide it into the convex wall cavity 132.

[0044] A preferred specific structure is that the hair curler 1 includes two matching and interlocking body segments 10 to form the hair curler 1. This structure allows the hair curler 1 to be composed of two separate body segments 10, making it easier to shape the complex internal structure of the hair curler 1. Specifically, the spiral hair-winding grooves 12 of the two body segments 10 match and correspond to form a complete spiral hair-winding groove 12, and the spiral convex walls 13 of the two body segments 10 match and correspond to form a complete spiral convex wall 13. The two body segments 10 can be directly matched and interlocked to form a structure including a complete shell, a complete spiral hair-winding groove 12, and a complete spiral convex wall 13. The joint of the two body segments 10 can be connected by conventional connection methods such as ultrasonic welding, gluing, and screw fixing.

[0045] The product form of the present invention is not limited to the illustrations and embodiments shown in this case. Any appropriate changes or modifications made to it based on similar ideas should be considered as not departing from the patent scope of the present invention.
