The sodium bicarbonate solution and the acetic acid or the oxalic acid are used as reaction raw materials, and the method also has the advantages of low cost, non-toxic raw materials and environmental protection.
The colored liquid 40 is preferably a liquid with a dark color and low light transmittance, such as a copper sulfate solution, iodine, etc., so that when the colored liquid 40 moves between the light source 31 and the illumination sensor 32, the illumination received by the illumination sensor 32 can be effectively reduced. Specifically, in this embodiment, the colored liquid 40 may be any one of a black ink and a potassium permanganate solution, and the using effect is better. In addition, the light source 31 is preferably a laser light source, so that under the shielding effect of the colored liquid 40, the change of the illumination intensity received by the illumination sensor 32 is more obvious, and the change of the signal detected by the controller is also more obvious. Further, in this embodiment, the controller is composed of a single chip microcomputer and a relay, the single chip microcomputer is connected with the illumination sensor 32, an input end of the relay is connected with the single chip microcomputer, an output end of the relay is connected with a working circuit, and the single chip microcomputer sends an instruction to the relay when detecting that the illumination intensity received by the illumination sensor 32 is lower than a preset threshold value, so that the working circuit is controlled to be disconnected through the relay.

For the liquid pipeline 20 in the U-shaped arrangement, when the colored liquid 40 moves rightward until the colored liquid 40 is located in the right half portion of the liquid pipeline 20, a small amount of gas in the reactor 10 escapes from the second end of the liquid pipeline 20 through the colored liquid 40 in the form of bubbles, which may cause the liquid level on the right side of the colored liquid 40 to fluctuate up and down easily, and easily cause the working circuit to be disconnected and connected many times in a short time, thereby affecting the control accuracy of the device 100 for controlling the timed connection and disconnection of the working circuit through chemical reaction. In order to avoid this phenomenon, in this embodiment, the dark box 33 is spaced from the buffer chamber 21, and preferably, the dark box is disposed at least 1cm below the buffer chamber 21, so as to provide a certain liquid level fluctuation space for the colored liquid 40.
