Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] This invention relates to a steam arcer.

[Background technology]

Conventionally, as shown in FIG. 10, as a steam generating device for a steam arcer, a water absorbing body 92 is provided in a tank 91 containing water, and a hot plate 93 is brought into contact with this water absorbing body 92 to generate steam. A method has been proposed (Japanese Patent Publication No. 53-47744).

The hot plate 93 has a built-in heater 94. The biggest drawback of this steam generator is that the amount of steam generated is unstable. In this type of steam generator, the internal pressure of the tank has a large influence on steam generation. First, by generating steam and reducing the water in the tank 91, the tank internal pressure P8 becomes negative pressure (a pressure lower than atmospheric pressure).

The relationship between the degree of negative pressure and the amount of steam is such that as the negative pressure increases, the amount of steam decreases, as shown in FIG. Therefore, stably managing the negative pressure generated within the tank 9 will stabilize the performance of this type of steam generator.

For this reason, conventionally, when negative pressure occurs in the tank,
It was thought that the amount of steam could be ensured by sucking air through the tube and not increasing the negative pressure. but,
According to this method, the air suction effect of the felt is unstable due to unstable factors such as the narrowness of the felt mesh and variations in the compression amount due to the structure, and as a result, it is difficult to maintain a constant tank internal pressure. , it becomes difficult to stabilize the amount of steam.

Furthermore, the disadvantage of the internal pressure adjustment method using felt is not only the instability of the amount of steam. Tank internal pressure approaches atmospheric pressure (
If the negative pressure decreases), water will begin to leak from the tank. Consider the case where tank 9] is facing downward as shown in Fig. 12. Water from tank 91 in this state? ? E
In order to prevent water drop, it is necessary to make the negative pressure inside the tank and the water holding pressure of the water absorbing body 92 higher than the water column pressure Ph.

According to the experimental value under certain configuration conditions of Tank 9, Ph is 5.
When 0 rtun A9, Ps is -30run A
It has been found that water drips unless the pressure is set to a negative pressure of 9 or higher.

As mentioned above, the drawback of the conventional method is the unstable suction effect due to the felt, which causes large fluctuations in the tank internal pressure.
If the negative pressure inside the tank is too large, the amount of steam will decrease, and if the negative pressure inside the tank is too small, the amount of steam will increase, but the performance will be unstable, resulting in water leakage. Therefore, in a bare curler equipped with such a steam generator, there is a problem in that the curl diameter of the hair changes as the amount of steam changes, making it impossible to achieve stable curling performance.

[Purpose of the invention]

The object of the present invention is to provide a steam curling device in which the internal pressure of the tank is stabilized, thereby the amount of steam is stabilized, water leakage does not occur, and the curling performance of the steam is stable.

The clip body 14 includes a plurality of fixing pins 14a, and the cylindrical portion 14b is fitted into the inner circumference of the winding drum body 5 to be slidable. The locking portion 14c provided on the circumferential surface of the cylindrical portion 14 is caught on the end of the winding drum body 15 and is prevented from being pulled out, and the locking portion 14CI/i slides between the notches 15e of the winding drum body]5. do. In addition, the fixing pin 14a is inserted into the hole 15 provided at the end of the winding drum body 15.
It is configured to slide through the hole c. A plurality of locking holes 15d are formed in one end of the winding drum main body J5, into which locking pieces 13a of the winding drum holding attachment 13 are inserted, and the locking pieces 13a are held by the bulge at the tip. It is now possible to do so. The steam rod 12 and the winding drum body 5 each have steam discharge holes 12a and 15b. Reference numeral 15a denotes a hair wrapping protrusion formed on the winding drum body [5].

Operation As shown in Fig. 2, first open the lid 32, take out the tank block b2, separate the tank 5 from the water absorbent surface (10) and the fixed frame 6, fill the tank 5 with water, and remove the tank 5 and the water absorbent body. The fixing frame 6 is recombined and placed in the main body 31, the lid 32 is tightened, and water is prepared. Next, switch handle 2
0 to turn on one or two PTC heaters 1 and heat the hot plate 3.

When the contact surface 3d of the water absorbent reaches a temperature at which steam can be generated, steam is generated, and due to the capillary action of the water absorbent 0, water is sucked up one after another to the steam generating portion, and steam is continuously generated. If you want strong curls, turn on two PTC heaters 1 to increase the amount of steam. Gentle (
When you want to create curls (weak), you can adjust the amount of steam by turning on one PTC heater 1. The steam generated at the water absorbent contact surface 3d is transferred to the steam passage 3.
Steam vibe from the steam outlet 53 through b]2
sent inside. PTC is installed above and below the steam passage 3b.
Because the heater taco is located, the temperature will be high.
Condensation during this period is avoided. In other words, the PTC heater 1 has the effect of both generating steam and preventing condensation. steam pipe J2
The temperature is also maintained at a high temperature by the second heater IJ, and no condensation occurs even if steam is continuously generated. When steam starts coming out from the discharge hole 12a of the steam vibrator 12, the hair wrapping cylinder C is placed in the steam vibrator 12. Hair roll C
When the steam vibrator 12 is inserted, the clip body [4] is pushed out by the tip of the cap [7], and the locking piece 13a of the winding drum holding attachment 13 is inserted into the locking hole 15 of the winding drum main body 15.
d and held.

Wrapping the entire hair with steam coming out from the outer periphery of the steam pipe 12 (steam is added to the hair during the winding operation), and when the winding is finished, pull out the entire steam pipe 12 from the winding trunk body 15 (the winding is complete). Figure 4 (B)). After the entire steam pipe is pulled out from the barrel, the clip body 14 is pushed to insert the bottle 14a into the hair bundle and the curler is fixed above the user's head. By repeating such an operation, the hair winding cylinder C is wound one after another. Experiments have shown that sufficient curling can be achieved if the hair is held on the head for 2 minutes or more.

While steam is being generated, when the internal pressure of the tank 5 reaches a certain level of negative pressure, the bulk part of the valve body 7a of the pressure regulating valve 7 opens and sucks air through the air vent hole 6a, keeping the negative pressure constant. Prevent the value from rising above the specified value. For example, the valve body 7a
When the valve opening pressure is set to -30txtnAq, the internal pressure of the tank 5 becomes stable around -30wnAq. According to this structure, unlike the suction effect of conventional felt, it becomes possible to numerically manage the internal pressure of the tank 5. In this way, since the internal pressure is stabilized, the amount of steam generated is stabilized, and stable curling performance can be obtained. Furthermore, leakage of water from the water absorbent body 10 is prevented.

Although it operates in this way, since the hair winding cylinder C, the heater block b, the tank block b2, and the rotary connector 29 are arranged in a straight line, the main body 3I can be formed into a set that is easy to grip. Furthermore, since the rotary connector 29 is provided at the end of the main body 31, it does not get in the way of gripping, making it easy to use. Moreover, since the one-turn connector 29 is freely separable from the main body 3,
The tank ( ] 3) 5 can be easily attached and detached from the end of the main body 31 on the rotary connector 29 side. This embodiment includes a spring 28 that presses the water absorbing body 10 against the heater block b, and a pushbutton 23 that locks these in a separated state.

Therefore, by separating the water absorbing body JO from the heater block B, instantaneous generation and stopping of steam can be stably performed.

FIG. 5 shows a second embodiment. In this example, a plurality of pressure regulating valves 7□ to 74 are provided around the entire circumference of the water absorbent fixing frame 6. This configuration has the following advantages compared to the first embodiment. That is, the first embodiment has the following problems. When applied to a hand-held device, the main body 3 is rotated, so the positional relationship between the pressure regulating valve 7 and the water surface is constantly moving. In the case of the water surface position shown in FIG. 5 (5), the valve body 7a is located in the space within the tank 5, and the valve opening pressure is operated by the valve opening pressure of the valve body 7a itself. Not affected by water column pressure. However, in the case of the water surface position shown in FIG. 5(R), the water column pressure Ph affects the valve opening pressure of the valve body 7a, and Ph0
The valve opening pressure of the valve body 7a increases accordingly. In other words, (14) By changing the relative position between the valve body 7a and the water surface,
The opening pressure of the valve body 7a fluctuates, the tank internal pressure becomes unstable, and as a result, the amount of steam also becomes unstable. On the other hand, in the embodiment shown in Fig. 6, no matter where the water surface is,
Some part of the valve body 7a is exposed to the air layer, and a stable valve opening pressure can always be obtained. Therefore, the internal pressure of the tank can be stabilized, and as a result, the amount of steam can be stabilized. The rest is the same as the first embodiment.

FIG. 7 shows a third embodiment. Like the second embodiment, this embodiment also aims to improve the stability of the tank internal pressure when applied to a hand-held device.

In this embodiment, all the pressure regulating valves 7 are provided coaxially with the axes of the heater block b□ and the tank block b2. That is, a valve body 7a and an air vent hole 5 are provided at the bottom of the tank 5'.
It consists of a. By doing this, even if the main body 31 rotates and the water level in the tank changes, the opening pressure of the valve body 7 can be stabilized as in the second embodiment, and as a result, the amount of steam can be stabilized. A steam generator can be obtained. The rest is the same as the first embodiment.

FIG. 8 shows the entire fourth embodiment. In this example, an air vent hole 80 is provided at the bottom of the tank 5', and a truncated conical valve body 8]a is provided which opens and closes the air vent hole 80i by being biased by a spring 81'. It is composed of The rest is the same as the first embodiment.

FIG. 9 shows a fifth embodiment. In this example, a rubber plate-shaped valve body 82a f made of silicon or the like is provided in an air vent hole 80 at the bottom of a tank 5'', and the valve body 82a is pressed with its own elasticity to maintain an airtightness.Valve body 82a A pressure regulating valve 82 is constituted by the air vent hole 80 and the air vent hole 80.Others are the same as in the first embodiment.
