PROBLEM TO BE SOLVED: To provide a carbon dioxide concentration regulating apparatus which artificially generates a carbonated spring.SOLUTION: In a carbon dioxide regulating apparatus, a carbonic acid generator comprises two pressure vessels 1, 20 in communication with each other through a communicating tube 6C. The carbonic acid generator is a carbonated spring generator that has a carbon dioxide gas in an upper space in one of the pressure vessels and has a mode of storing warm carbonic acid water in a lower part thereof. Warm water is ejected against a warm water surface within the one pressure vessel from the upper part of the pressure vessel so that collision agitation is allowed to occur on the liquid surface to absorb carbon dioxide gas in the liquid. When the inside of the pressure vessel is filled with the warm water, the water level within the other pressure vessel communicated through the communicating tube is increased in conjunction with the filling of the warm water and, further, the level of a float 6 present within the other pressure vessel is also increased. The buoyancy of the float is utilized so that a carbon dioxide gas supply control valve is moved to start the supply of the carbon dioxide gas.COPYRIGHT: (C)2013,JPO&INPIT【課題】炭酸泉を人工的に生成する、炭酸濃度制御装置を提供する。【解決手段】連通管6Cで繋がった2つの圧力容器1、20を有する炭酸生成装置で1方の圧力容器の上部空間に炭酸ガスを有し、下部に炭酸温水が貯留する方式の炭酸泉生成装置に於いて、1方の圧力容器内の温水面に上部から温水を噴射して液面に衝突攪拌を起させて炭酸ガスを吸収させ該圧力容器内に温水が充満してくると連通管で繋がった他方の圧力容器内の水位も連動して上昇し、その中に在るフロート6も水位の上昇にしたがって上昇し、このフロートの浮力を利用して炭酸ガス供給制御弁を動かし炭酸ガスの供給と開始を行うようにする炭酸ガス制御装置。【選択図】図1
