Description

[Detailed explanation of the invention] [Industrial application field] This invention is a facial treatment that corrects skin imbalances and pushes out acne by applying oil to rough skin and soap to oily skin and applying steam. This relates to the steamer used when applying the product.

[Conventional technology and its problems]

The steamer used for traditional facial treatment is the first
As shown in Figure 2, a pipro with a rotatable steam injection nozzle at its tip is attached to the side of a tank housing a built-in heater (not shown), and a cartridge tank is mounted on the tank. When the water in the tank boils and steam is generated, and the liquid level drops below the specified liquid level, water is constantly replenished by air replacement, thereby making the degree of steam injection from the nozzle uniform.

Further, the liquid level in the tank is set to about 1/3 to 1/4 of the depth of the tank from the bottom, and the generated steam is stored in the upper space of the tank to make the injection degree of the steam uniform.

Therefore, the valve stem protrudes long from the base of the cartridge tank, and this valve stem is supported by a cylinder pipe.
An air exchange hole is provided in the middle of the cylindrical pipe at a portion that corresponds to the specified liquid level.

By the way, the cartridge tank loading opening of the tank should be large enough to receive and support the mouthpiece of the tank, and an airtight fit should not be adopted so that there is no problem in attaching and detaching the cartridge tank for refilling the liquid. As a result, steam leaks from the cartridge tank loading port, so a guide tube surrounding the tube tube is suspended from the loading port to a position lower than the specified liquid level.

However, when the guide tube is hung down like this,
If the internal pressure of the tank were to exceed normal pressure, the liquid level would drop as shown in Figure 3, and the liquid level inside the guide cylinder would rise by that amount, even though the liquid level inside the tank would fall. When the liquid replenishment stops and the liquid decreases with the generation of steam, and the liquid level in the guide cylinder falls to the air exchange hole, a small amount of liquid is replenished, and the temperature decreases and the vapor pressure decreases, causing the liquid in the tank to drop. There is an inconvenience that the surface level rises, the liquid level in the guide cylinder further falls, a large amount of liquid is replenished, the temperature of the liquid further decreases, and steam jetting stops for a while. In the figure, wa indicates the power cord, ka indicates the iozone switch, and y indicates the timer knob.

[Means for solving problems]

In order to solve the above problems, this invention has a guide tube with a hole with the same or smaller diameter at the same perpendicular position as the hole, slightly below the air exchange hole in the middle of the valve stem protection tube. This facial steamer is provided with a hole and a layer of pot packing that is sized to closely fit the inner surface of the guide tube on the upper part of the valve stem protection tube of the mouthpiece.

[Effect]

If steam is generated in the steam generation tank and is ejected from the nozzle, the internal pressure will rise, the liquid level in the tank will be pressurized, and the liquid level in the guide cylinder will be higher than the air displacement hole. However, steam blows into the hole on the side of the guide tube, turns into bubbles, flows into the air displacement hole, and replaces the water in the cartridge tank with air.
The liquid level in the tank should always be maintained at the specified level.

〔Example〕

Figure 4 shows the main parts of the facial steamer according to the present invention, 1 is a steam generation tank, 2 is a tank 1
It is a cartridge tank loaded on top. The heating mechanism of the tank 1 is not shown.

3 is a cartridge tank loading port formed in the tank 1, 4 is a cap of the cartridge tank, 5 is a valve stem built into the cap 4, 6 is a valve stem protection tube, and 7 is a valve stem protection tube 6. The air exchange hole 9 formed in the part corresponding to the specified liquid level 8 of the tank 1 hangs integrally with the cartridge tank loading port 3, and the lower end is below the specified liquid level 8. This is a guide cylinder to prevent steam from flowing out.

There is nothing different from the conventional steamer. In addition, the tank 1 is provided with a rotatable pipe for rotatably providing a steam injection nozzle, but this is also omitted from illustration as it is similar to a conventional steamer.

In particular, this invention has a valve stem protection tube 6 attached to the guide tube 9.
Slightly lower than the air exchange hole 7 and the same hole 7
A hole 10 having a diameter equal to or smaller than that of the hole 7 is provided at the same perpendicular position as the hole 7, and a layer 11 of hook packing is provided on the upper part of the valve stem protection tube 6 so as to be in close contact with the inner surface of the guide tube 9. is provided.

Further, the air exchange hole 7 of the valve stem protection tube 6 and the hole 10 of the guide tube 9 are provided on the four circumferential surfaces.

〔effect〕

If steam is generated in the steam generation tank and used for facial treatment, the internal pressure of the tank should rise and the liquid level in the tank will be pressurized, causing the liquid level in the guide cylinder to form in the middle of the valve stem protection cylinder. Even if it rises above the hole,
When the liquid level in the tank falls below the specified liquid level, the hole on the circumferential side of the guide cylinder is exposed from the liquid level and steam is blown into this hole, and at the same time, the cartridge tank loading port in the guide cylinder becomes airtight due to the presence of packing. The air inside the guide cylinder is held in a pressurized state without leaking, so when the steam blown into the hole in the guide cylinder is released into the liquid inside the guide cylinder, it becomes bubbles and the air on the opposite surface is released. The air bubbles are now sent into the displacement hole and are replaced with the water in the cartridge tank, thereby replacing the water (hot water) in the steam generation tank.
The liquid level is always maintained at a specified level, so the amount of steam injected from the nozzle becomes uniform.
