- a gas detection stroke position P4 between the stroke position P3 and the stroke position P3 is taken. When the gas detection stroke position P4 is taken, the gas pressure is detected. Heating by the heater 2 33 is performed from the second position P 2 to the maximum stroke position P 3, and then immediately before reaching the gas detection stroke position P 4. When the gas pressure is detected, the heater 23 3 is turned off. .
- a ring 270 extending all around the side surface of the cam member 241.
- a notch may be provided in the ring 270, and the notch may be detected by the optical sensor 271 to detect the cam rotation angle.
- the description has been limited to the detection of the dissolved carbon dioxide concentration of carbonated water (including carbonated springs).
- the present invention is not limited to this, but can be applied to widely and generally detect the concentration of dissolved gas in a liquid.
- the carbon dioxide spring generator of the above-described embodiment eliminates the part where the performance is deteriorated due to dirt, and continuously contacts the hot water and the carbon dioxide gas under a pressure higher than the atmospheric pressure, thereby continuously converting the carbon dioxide gas. It can be absorbed in water.
- the carbon dioxide gas in the high-pressure vessel is consumed only by being absorbed by the water, so the consumption of the carbon dioxide gas is small, and the hot water in the bathtub can be repeatedly and continuously treated. This makes it possible to compensate for the decreasing concentration and keep the carbonated spring at a high concentration at all times.
- the carbonated water generation system according to the present invention is used, for example, at home, it is possible not only to enjoy a carbonated spring at home every day, but also to promote the development of capillaries, for example, to prevent itching of senile skin and limbs for diabetes. It can prevent the occurrence of necrosis that occurs in the elderly, and can cure bedridden elderly people's ulcers. Even for young people, it is extremely important to enhance the development of capillaries to relieve fatigue in a stressed society, so the development of capillaries rejuvenates the skin and is effective for women's beauty. It is a target.
- a trace mineral that is effective for various bodies is added to the carbonated spring to provide a more effective hot spring than a natural hot spring.
- a trace mineral that is effective for various bodies is added to the carbonated spring to provide a more effective hot spring than a natural hot spring.
- zeolite or the like by dissolving a small amount of sulfide gas in carbonated springs using zeolite or the like, a more effective hot spring effect than natural hot springs can be obtained.
- carbonated water as the water used in the outdoor pool and the heated pool, the health and beauty effects of the carbonated water can be obtained while playing in the pool.
- the carbonated spring to sterilization with silver ions, Z or hypochlorous acid, etc., it is possible to extremely effectively sterilize Escherichia coli and Legionella bacteria, which are social problems.
