1. Field of the Invention
The present invention relates to a hair styler and a heating device, and more particularly to an electromagnetically heated hair styler, and the temperature condition of the hair styler is easily recognizable.
2. Description of the Prior Art
It is to be noted that, during hair styling by hot perming, perm lotion is usually used to modify the hair texture after rolling hair with hair rollers, then mold the hair into a desired style by heating, hence, temperature control is key to the hair styling effect. However, hair will form a certain thickness of hair layer after winding around the hair roller, so that, the hair at the top surface of the hair layer that touches the hair roller as shown in
Besides, the conventional electric heating devices 80, 800 require constant power supply, therefore, the hair rollers 90, 900 need to be connected with a power line, which not only increases the size of the hair styler, but also makes the use of the hair styler inconvenient during hair styling. Furthermore, the hair styler is required to be maintained at the temperature of 120-180 Celsius degrees during the whole process of hair styling, which suffers the disadvantage of high energy consumption. Another disadvantage is that perm lotion used in hair styling will inevitably be brought into contact with the hair rollers and clips, which makes the hair rollers and clips difficult to clean and causes sanitation problem.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary objective of the present invention is to provide a hair styler and its heating device, wherein the thermal storage piece inside the hair roller can be quickly heated to a desired temperature by electromagnetic heating. The thermal storage piece is made of high thermal conductivity material which can absorbs heat quite quick, and then a low thermal conductivity isolating layer retains the heat within the hair roller and enables the heat to be uniformly and constantly transmitted to the outer surface of the hair roller, providing an effect of low energy consumption and long-lasting heat.

Yet another objective of the present invention is to provide a hair styler and its heating device, wherein a thermal storage piece is disposed inside the base of the hair roller or the hair clip, so as to prevent the hair from directly contacting the thermal storage piece during hair styling, and consequently preventing the hair from being burned.
Yet another objective of the present invention is to provide a hair styler and its heating device, wherein a plurality of thermal fins are arranged around the outer peripheral surface of the hair roller to fix the hair and to transmit heat to the outer layer of the hair, allowing the hair to be uniformly heated.
Yet another objective of the present invention is to provide a hair styler and its heating device, wherein a temperature sensing piece is used to detect and indicate the temperature of the hair styler by using different colors, making it easier for the user to know the temperature of the hair styler easily.

Referring to
As shown in
The hair styler of the present invention can be the hair roller A which can be used independently after being electromagnetically heated, or the hair styler of the present invention can be the combination of the hair roller A and the hair clip C. As shown in
The heating device B of the present invention serves to quickly heat the hair roller A by using the steel made thermal storage piece 30. The thermal storage piece 30 is formed along the axial direction of the base 10 with a slot 31 which makes the thermal storage piece 30 expandable and flexible, so that the thermal storage piece 30 can be flexibly pressed against the isolating layer 20. The isolating layer 20 between the base 10 and the thermal storage piece 30 is able to retain the heat within the hair roller A. Besides, the isolating layer 20 which is made of low thermal conductivity material allows the heat to be evenly and smoothly distributed over the outer surface of the hair roller A via the base 10 and the thermal fins 12, so that temperature retaining structure of the hair roller A, after being heated, can be maintained at a relatively high temperature for a long time to enable the hair roller A to perform hair styling. The isolating layer 20 is preferably made of mica.
An end surface of the base 10 of the hair roller A is formed with an engaging groove 14 for holding a temperature sensing piece 13 whose color changes with temperature. One end of the thermal storage piece 30 extends toward the temperature sensing piece 13 to form a heat transmission piece 32 with a connecting section 321 which is to be pressed against the inner surface of the inner chamber 11 of the base 10. Heat stored in the thermal storage piece 30 of the hair roller A is transmitted to the base 10 via the heat transmission piece 32 to enable the temperature sensing piece 13 to detect the temperature condition of the hair roller A. For example, the color of the temperature sensing piece 13 is red at a room temperature, and will change into white when the temperature of the hair roller A reaches a predetermined value, so as to remind the user that the hair roller A has been heated to a desired temperature.
In this embodiment, as shown in
The hair roller A and the hair clip C are electromagnetically heated, and the two inner arc-shaped surfaces 531 of the two clip members 501, 502 are clamped against the outer periphery of the hair roller A to fix the hair winding around the roller A. The hair roller A and the hair clip C are uniformly heated by the temperature retaining structure, including the thermal storage layer 55 and the isolating layer 20, respectively, and the arc-shaped portions 53 of the hair clip C are clamped against the outer surface of the base 10 of the hair roller A so as to further reduce the heat dissipation of the hair roller A, maintaining the hair roller A at a relatively high temperature for a long time while preventing the hair from being brought into direct contact with the high temperature elements of the hair roller.
In this embodiment, each of the outer arc-shaped surfaces 532 of the arc-shaped portions 53 of the hair clip C is formed with a receiving groove 533 and an assembling groove 534. The temperature sensing piece 54 which changes color with temperature is received in the receiving groove 533 to indicate the temperature condition of the clip C. The assembling groove 534 is a stepped structure, the thermal storage layer 55 is disposed at a bottom of the assembling groove 534, and a positioning member 56 is disposed at the top of the assembling groove 534 to fix the thermal storage layer 55.
To summarize, the hair styler and the heating device of the present invention offer the following advantages:
1. using electromagnetic heating method to heat the high thermal conductivity steel made thermal storage piece 30, and then using the low thermal conductivity isolating layer 20 to transmit heat from the thermal storage piece 30 at a constant rate to the hair roller A. Hence, as compared to the conventional hair styler, the present invention has less electricity consumption and can maintain the hair roller A at a high temperature for a longer time.
2. thermal fins 12 around the outer peripheral surface of the base 10 of the hair roller A is used in combination with the hair clip C to allow hair to be more easily fixed and styled, and also allow the hair to be heated more uniformly.
3. the temperature sensing pieces 13, 54 make it easier to know the heating and temperature condition of the hair styler, preventing that the temperature is too low to effect the hair styling affect or the temperature is too high to burn the hair.
4. the electromagnetic heating method not only has the advantages of fast heating and low energy consumption, but also simplifies the hair styler, making the use of the hair styler easier.
