Technical field:

The present invention generally relates to a curling iron that uses a thermal fluid as its heat source. More specifically, the present invention relates to a hair curler that uses a thermal fluid as its heat source for heating hair, thereby maintaining a constant temperature that can achieve the desired curling effect while preventing excessive temperature rise to avoid damaging the hair.

Background technique:

As known to those skilled in the art, conventional hair curlers for curling hair usually use electric coil heaters as their heat source. Such electric coil heaters for hair curlers generate heat when energized, so that the heat is directly transferred from the heater to the hair during the curling process.
However, the above-mentioned conventional hair curler has a problem in that since the conventional hair curler is repeatedly opened and closed, it cannot maintain a constant temperature. In this way, the curling effect of the conventional curling iron is reduced. In addition, the temperature of the heater of the conventional hair curler sometimes rises excessively during the curling process, and in this case, the hair may be thermally damaged.

Summary of the invention:

Therefore, the present invention is made in response to the above-mentioned problems in the prior art, and the object of the present invention is to provide a hair curler, which uses a thermal fluid as its heat source for heating hair, so as to maintain that it can achieve the desired The curly hair effect can prevent the temperature from rising too much to avoid damaging the constant temperature of the hair.
In order to achieve the above object, the present invention provides a hair curler, comprising: a hot fluid used as a heat source of the hair curler; a fluid heating unit that transfers the heat of the hot fluid to hair to curl the hair; and curling hair The tongs support the heating unit so that the heating unit heats the hair when the curling tongs clamp the hair.

Brief description of the drawings:

The above and other objectives, features and other advantages of the present invention will be more clearly understood through the following detailed description in conjunction with the accompanying drawings, in which:
Figure 1 is a perspective view of a hair curler according to a preferred embodiment of the present invention; and
Fig. 2 is a cross-sectional view of the curling iron of Fig. 1.

The best way to implement the invention:


Refer now to the drawings, in which the same reference numerals are used throughout the different drawings to refer to the same or similar components.
Fig. 1 is a perspective view of a hair curler according to a preferred embodiment of the present invention. Fig. 2 is a cross-sectional view of the curling iron of Fig. 1.
The hair curler of the present invention uses a thermal fluid as the heat source for heating the target (ie, hair), and in the preferred embodiment as shown in the figure, the thermal fluid is steam 100. The temperature of steam 100 usually rises to 100-150 °C, so that steam 100 is sufficient to heat the hair without thermally damaging the hair.
The hair curler of the present invention has a fluid heating unit for heating fluid as a heat source. In this preferred embodiment, the fluid heating unit is a steam generator 200, which is electrically operated to generate steam 100. The steam generator 200 includes a plurality of steam outlets 210, a plurality of steam supply control switches 212, a plurality of condensate inlets 220, and a plurality of check valves for preventing the undesired steam flow 100 from entering the condensate inlet 220.
The power cord 230 and the power switch 232 are provided on the steam generator 200. The power cord 230 is used to supply current from the power source to the steam generator 200, and the power switch 232 is used to turn the steam generator 200 on or off.
The hair curler of the present invention also has a heating unit for transferring the heat of the steam 100 to the hair to curl the hair. The heating unit includes a steam supply pipe 300 connected to one of the steam outlets 210 of the steam generator 200 to supply the steam 100 from the steam generator 200 to the steam storage/heating pipe 310. The steam storage/heat pipe 310 receives the steam 100 supplied through the steam supply pipe 300, stores the steam 100 therein, and transfers the heat of the steam 100 to the hair. The condensed water discharge unit 312 is connected to the steam storage/heating pipe 310 to collect the condensate generated by the condensation of the steam 100 in the steam storage/heating pipe 310 before returning the condensed water to the steam generator 200 through one of the condensate inlets 220 water. Both ends of the condensate return pipe 320 are connected to the condensate discharge unit 312 and one of the condensate inlets 220, and return the condensed water from the condensate discharge unit 312 to the steam generator 200 through the condensate inlet 220.

When the steam 100 is supplied from the steam generator 200 to the steam storage/radiation pipe 310 through the steam supply pipe 300, the steam 100 heats the steam supply pipe 300. In this way, when the user accidentally touches the heated tube 300, the heated tube 300 may scald the user. In an attempt to overcome this problem, a heat insulating material is preferably used to coat the outer surface of the steam supply pipe 300.
The steam storage/heat dissipation pipe 310 is preferably made of a metal with high thermal conductivity, and has a shape that enables the steam storage/heat dissipation pipe 310 to effectively contact the hair during the curling process.
The hair curler of the present invention also includes curling tongs for supporting the heating unit so that the heating unit can heat the hair when the curling tongs clamp the hair. The curling tongs are composed of a handle 400, a main arm 410, a secondary arm 420, and a lever 430. The handle 400 is used as a grip of the curling tongs and a part of the steam supply pipe 300 passes through the handle 400 axially. The main arm 410 is connected to the handle 400 and supports the steam storage/heat dissipation pipe 310 therein. The auxiliary arm 420 is hinged with the main arm 410, so that when the hair is heated by the steam heat, the auxiliary arm 420 contacts the steam storage/heating pipe 310 of the main arm 410 to clamp the hair, or when the hair is heated from the steam storage/ The heat pipe 310 is moved away to loosen the hair. The lever 430 is connected to the sub-arm 420 so that the user can rotate the sub-arm 420 relative to the main arm along the chain point of the two arms 410 and 420.
As described above, since the steam generator 200 has multiple steam outlets 210 and multiple condensate inlets 220, multiple steam supply pipes 300 and multiple condensate return pipes 320 can be connected to the steam generator 200 at the same time.
Therefore, two or more curling tongs can use the steam generator 200 at the same time, so that two or more users can use only one steam generator 200 to curl the hair of multiple people at the same time. Therefore, the hair curler of the present invention is preferably used in a beauty shop or other places where there are multiple hairdressers curling hair for multiple people at the same time.
The operating effects of the hair curler of the present invention will be described below with reference to the accompanying drawings. First, the power switch 232 of the steam generator 200 is turned on to generate steam in the steam generator 200. Subsequently, the steam supply pipe 300 is connected to a selected steam outlet 210 of the steam generator 200, and the condensate return pipe 320 is connected to a selected condensate inlet 220. When the steam supply control switch 212 associated with the selected steam outlet 210 is turned on, the steam 100 flows from the steam generator 200 through the steam outlet 210 into the steam supply pipe 300.

After that, the steam 100 is supplied through the steam supply pipe 300 into the steam storage/heat dissipation pipe 310 supported by the main arm 410 of the curling irons. In the steam storage/heating pipe 310, the steam 100 heats the pipe 310 to make the pipe 310 radiate heat outward.
Therefore, when a user holding the handle 400 operates the lever 430 to close the main arm and the auxiliary arms 410 and 420, the two arms 410 and 420 clamp the hair, and the steam storage/heating pipe 310 uses the steam heat to heat the hair to Make the hair frizzy.
During the curling process, the temperature of the steam 100 in the steam storage/heating pipe 310 decreases, so that the steam 100 condenses to generate condensed water. The condensed water is first collected in the condensed water discharge unit 312 and then returns to the steam generator 200 through the condensed water return pipe 320 and the condensed water inlet 220. The condensed water discharge unit 312 is designed to discharge only the condensed water from the steam storage/radiation pipe 310 while preventing the steam 100 from leaking from the steam storage/radiation pipe 310 into the condensate return pipe 320.

Industrial applications:

As described above, the present invention provides a hair curler that uses a hot fluid as a heat source for heating hair. The hair curler of the present invention is composed of a fluid heating unit for heating fluid to generate steam as a heat source, a heating unit for transferring steam heat to hair to curl the hair, and a heating unit for supporting the heating unit so that the heating unit is clamped in the curling tongs It is composed of curling irons and curling tongs for heating the hair. Because the hair curler uses the hot fluid as the heat source for heating the hair, the hair curler maintains a constant temperature that can achieve the desired curling effect and prevent the temperature from rising too much to avoid damaging the hair.
Although the preferred embodiments of the present invention are disclosed for illustrative purposes, those skilled in the art will foresee that various improvements and additions will be made without departing from the spirit and scope of the present invention as disclosed in the appended claims. And replacement are possible.
