Carbonic acid concentration control method and carbonic acid solution generating device Technical Field The disclosure relates to the technical field of electrical control, in particular to a carbonic acid concentration control method, a carbonic acid solution generating device and related equipment. Background Carbonated water is a solution of carbon dioxide gas and water mixed together. Because carbon dioxide gas in carbonated water can play roles in expanding and softening blood vessels, promoting metabolism in newcastle, improving blood circulation of skin and the like after entering the body through skin, more and more products for carbonated water baths (such as carbonated spring shower and the like) appear on the market. The product for carbonic acid water bath comprises a water supply part for supplying water, a gas supply part for supplying carbon dioxide gas, and a mixing part respectively connected with the water supply part and the gas supply part to mix the water with the carbon dioxide gas to form carbonic acid spring. Currently, the product for carbonic acid water bath provided in the related art increases the concentration of carbon dioxide gas in carbonic acid springs mainly by the following two ways: First, by designing the structure of the relevant part of the product (such as the shower head of the carbonated spring shower), the contact area of the carbon dioxide gas and the water is increased, and the solubility of the carbon dioxide gas in the water is further increased, and in this way, the carbon dioxide concentration in the mixed carbonated spring water may not reach the ideal concentration due to the fact that the carbon dioxide gas is easily volatilized in the water. The second is that the solubility of the carbon dioxide gas in water is increased by manually controlling the gas outlet amount of a carbon dioxide gas supply part (for example, a carbon dioxide gas cylinder), and the gas outlet amount of the carbon dioxide cannot be accurately controlled in this way, so that the waste of the carbon dioxide gas is very easy to cause.

In some embodiments, controlling the carbon dioxide supply amount of the carbonic acid solution generating device according to the actual air pressure value of the carbon dioxide gas, the actual temperature value of the water and the actual carbon dioxide volume concentration value of the carbonic acid solution comprises calculating a theoretical mass concentration value of the carbon dioxide gas at the actual air pressure value and the actual temperature value according to the actual air pressure value of the carbon dioxide gas, the actual temperature value of the water and the actual carbon dioxide volume concentration value of the carbonic acid solution, inquiring a standard mass concentration value of the carbon dioxide gas at the actual temperature value based on a water capacity table of the carbon dioxide gas at the standard air pressure value, and adjusting the opening value of a carbon dioxide gas supply valve according to the actual air pressure value, the theoretical mass concentration value, the standard air pressure value and the standard mass concentration value to control the carbon dioxide supply amount of the carbonic acid solution g
