[0002] This application claims priority to U.S. non-provisional application No. 17 / 840,530, filed on June 14, 2022, the entire disclosure of which is incorporated herein by reference. Technical Field

[0003] The present disclosure generally relates to a hair styling device. Background Art

[0004] Hair styling is a very important part of personal fashion. Different occasions call for different looks, and hair style is an important feature of a person's self-image. Therefore, people often change their hairstyle to suit different outfits and / or occasions. Straightening hair may be desirable for certain occasions, while wavy curls are desirable for other occasions.

[0005] Hair styling tools and devices are very important in the lives of individuals due to their need for hair styling. A typical hair styling device consists of an electrical circuit and a heater that is used to heat the hair strands within a predetermined temperature range. The heated hair strands become softer, allowing them to be properly adjusted to achieve the desired shape. The most common heaters available in the market are cylindrical (for curling hair) and flat (for straightening hair).

[0006] Conventional irons produce high temperatures, which increase the chances of hair damage. In addition, using a tongs iron to straighten hair can damage the hair strands, making them brittle and causing split ends. In addition, the current hair styling process includes several complex steps, which is both time-consuming and harmful to the hair strands. In addition, long-term and repeated use of such products can cause damage to the scalp, which in turn leads to more unpleasant consequences such as skin allergies, hair loss, skin burns, etc.

[0007] Therefore, there is a need for a hair styling device that can style hair in a short time without causing any impact or damage to the hair. Summary of the invention

[0022] See also Figure 1 The hairdressing tool 10 includes a heating plate 12, which is bent into a U-shape in both the transverse and longitudinal directions. Figure 4 As shown, the heating plate 12 further includes a top plate 50 and a bottom plate 52 located below the top plate 50 . When the hairdressing tool 10 is in the closed position, the top plate 50 and the bottom plate 52 are arranged concentrically with each other.

[0023] Figure 2A is a front view of a top plate 50 having a plurality of concentric layers, Figure 2B 1 is a front view of a bottom plate 52 having multiple concentric layers. The heating plate 12 is generally made of a suitable material capable of withstanding high temperatures, such as but not limited to ceramic, titanium, titanium alloy, polytetrafluoroethylene, other metals, etc., and combinations thereof. In one embodiment, a metal is disposed on the inner side of the heating plate, and the metal is preferably titanium. The heating plate 12 is uncovered (i.e., the top plate 50 and the bottom plate 52 are uncovered). This allows heat to penetrate the hair more evenly and quickly. This feature is particularly suitable for curling hair. In addition, the lack of a cover on the heating plate 12 also helps to maintain the temperature at a certain level to avoid overheating and thermal damage to the hair. In addition, the heating plate 12 also has a free end 14, at which the gap between the concentrically arranged heating plates 12 can be controlled. Generally, when the heating plate is in a heating state, the hair to be styled will be placed at the free end 14 or pass through the gap between the concentrically arranged heating plates 12, and the user can style the hair as needed.

[0024] A typical means of heating the heating plate is to use a suitable heater (not shown). In this embodiment, the heater may include a phase transfer coefficient (PTC) based heater, a metal ceramic heater (MCH), a mica sheet heater based heater, a rope heater, etc., and combinations thereof. The device also includes a temperature sensor (not shown). Typical temperature sensors include negative temperature coefficient (NTC) thermistors or diodes with aluminum sheets. The temperature sensor is used to control a preset value. The temperature value can be predetermined in a temperature control circuit (not shown), and the user can set different temperatures.

[0025] In one embodiment, there may be three temperature control settings. Each of the above settings, along with the temperature setting and hair type setting, may be viewed on the display 60. The temperature control settings allow the user to select the desired setting for a particular hair type and to protect the hair from heat damage. Setting 1 is for fine hair and is set to 180 degrees Fahrenheit. Setting 2 is for thick hair and is set to 200 degrees Fahrenheit. Setting 3 is for coarse hair and is set to 350 degrees Fahrenheit.

[0026] In some embodiments, Figure 3 As shown, the hair styling appliance may further include a display 60. The display 60 may be configured to display the temperature so that the user can view the temperature of the desired heating setting.

[0027] Back to Figure 1 , the gap between the concentrically arranged heating plates 12 is controlled by a lever 16. The gap size can be adjusted by pushing or pulling the lever 16, and then the lever 16 is locked at a point corresponding to the predetermined gap size. An example of a locking means may include providing appropriate ridges (not shown), the position of the ridges corresponding to the appropriate gap size, wherein the protrusions on the lever can abut against the appropriate ridges. In addition, a gear-like structure can also be provided to achieve the same function. Other ways of controlling the gap size using the lever 16 may also be included within the scope of the present disclosure. Figure 1 In the illustrated embodiment, the lever 16 is located at the top end of the hair styling appliance 10 .

[0028] Distal to the free end 14 of the heating plate 12 is an attachment end 15, which is connected to a connecting handle 18, and the rest of the hair styling device 10 is connected to the heating plate 12 via the connecting handle 18. In one embodiment, the handle 18 may have finger grip indentations to enable the user to better hold and grip the hair styling device, thereby preventing the hair styling device from slipping out of the user's hand during operation.

[0029] In one embodiment, the heating plate 12 is configured to extend outwardly from the connecting handle 18 in a longitudinally curved manner (i.e., curved in a direction across the length of the hair styling device 10 and / or the heating plate 12) or in a diagonally downward direction relative to the display 60 on the top of the hair styling device, which facilitates the user to grasp and hold the hair styling device in an ergonomic manner and better control the hair styling device when in use. In addition, the U-shaped curve of the heating plate 12 that crosses the transverse axis of the hair styling device 10 (crosses the width of the hair styling device 10 and / or the heating plate 12, perpendicular to the longitudinal axis of the hair styling device 10 and / or the heating plate) and bends toward the customer's hair and head conducts heat faster and distributes heat more evenly to the hair compared to a flat-shaped plate. In addition, the smooth rounded edges and sides of the plate help shape the hair into a desired style, whether straightening, curling or waving the hair.

[0030] It should be noted that the size of the heating plate 12 can be varied and interchangeable to accommodate different lengths of hair. For example, a smaller device can accommodate shorter hair, while a larger device can accommodate longer hair. In more detail, a heating plate 12 with a size of 1"X5" can be suitable for very short hair, a heating plate 12 with a size of 2"X6" can be more suitable for short hair, a heating plate 12 with a size of 3"X6.5" can be more suitable for medium-length hair, and a heating plate 12 with a size of 4"X5" and 5"X7.5" can be best suited for long hair.

[0031] The hair styling device further includes a gripping portion 20, which is located at the distal end of the hair styling device away from the heating plate 12. The gripping portion 20 may include finger indentations to enhance the user's grip. In addition, the gripping portion may be made of a suitable material such as rubber, which may also enhance the user's grip. In addition, the gripping portion may also be made of a heat-insulating material (such as plastic, rubber, composite material, etc.). In this way, the user can be protected from the heat emitted by the heating plate 12.

[0032] The hair styling appliance 10 also includes a stand 22 configured to allow the appliance to be supported on a surface such as a table or floor when not in use. Figure 1 One embodiment of a bracket 22 is shown, configured to be perpendicular to a base plate 52 attached to the handle 18, and the bracket 22 supports the tool when not in use.

[0033] The hair styling device also includes a power module 26 that allows the heating plate to be heated. The power module 26 may include a DC power source (e.g., a battery) or may be configured to be connected to an AC power source. The voltage and power of the battery provided may be determined according to the needs of the device. In addition, the battery may be rechargeable or easily removable to facilitate external charging, replacement, etc. In addition, the battery compartment may be configured to receive multiple batteries to achieve the voltage required to power the device.

[0034] In some embodiments, hair styling device 10 may further include: Figure 3 The display 60 shown is used to display any number of messages to the user. The display 60 can be in the form of numbers, letters, or alphanumeric codes, each of which corresponds to specific information to inform the user of the current status of the device. For example, the message H can mean that the device is still heating, while the message R can mean that the device is ready for use, and so on. Typically, the device will come with a manual that lists the codes and their meanings for the convenience of the user. A larger display 60 can be used to display more complete words and sentences to convey the status to the user.

[0035] Figure 4 1 is a perspective view of the hair styling appliance 10 showing the top heating plate 50 and the hair styling appliance 10 also including a bottom plate 52 connected to the handle 18 . Figure 5 is a front view of the hair styling device.

[0036] The present disclosure is directed to a hair styling device 10 that is versatile and can handle any type of styling (e.g., straightening, curling, or waving hair). The U-curve of the heating plate 12 allows heat to be transferred through the hair more quickly than conventional hair styling devices to effectively heat the hair strands. More efficient heat transfer allows the hair to be exposed to heat for a shorter period of time, which in turn prevents hair breakage.

[0037] Additionally, an LED (indicator light) is provided as a safety feature on the hair styling appliance 10. Thus, when the tool is off, the indicator light is off, and when the appliance is on, the indicator light will be green. Furthermore, the hair styling appliance automatically shuts off when the appliance has not been used continuously for the last 30 minutes, which prevents the hair styling appliance 10 from becoming a fire hazard or consuming electricity unnecessarily.

[0038] In addition, the disclosed hair styling device 10 is provided with a bracket 22 perpendicular to the base plate 52 attached to the connecting handle 18, and the bracket 22 supports the hair styling device 10 when not in use. The bracket 22 can effectively prevent skin burns when the device is used in an immature use situation.

[0039] Because the disclosed hair styling device 10 is uniquely designed, there is no need to replace the plates on the connecting rod 18 according to different uses. That is, the hair styling device 10 can be used to curl hair, make hair wavy, and straighten hair.

[0040] Although only certain features of the present disclosure have been illustrated and described herein, many modifications and changes will occur to those skilled in the art. It should be understood, therefore, that the appended claims are intended to cover all modifications and changes that fall within the true essence of the present disclosure.
