The technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention.

As shown in fig. 1, a water seal apparatus according to an embodiment of the present invention includes a liquid storage tank 10, a drug dissolving tank 20, and a U-shaped pipe 30. The liquid storage tank 10 is cylindrical and comprises a top cover 10a, a base 10b and a side wall 10c connecting the top cover 10a and the base 10b, an overflow port 11 is arranged on the side wall 10c, the overflow port 11 is used for keeping the solution in the liquid storage tank 10 at a certain liquid level, and when the solution in the liquid storage tank 10 is too much, the redundant solution can flow out through the overflow port 11. The medicine dissolving box 20 is a hollow box structure, sodium hydroxide solution is stored in the medicine dissolving box 20, and the medicine dissolving box 20 is preferably made of PP or PE materials. One end of the U-shaped pipe 30 is connected with the medicine dissolving tank 20, the opposite end is connected with the overflow port 11, a sodium hydroxide solution is stored in the U-shaped pipe 30, the sodium hydroxide is used for reacting with carbon dioxide in the air so as to eliminate impurities such as carbon dioxide in the air, and the U-shaped pipe 30 is preferably made of a transparent material such as UPVC. Through setting up U-shaped pipe 30, can make the solution in the liquid reserve tank 10 isolated with the outside air, and then ensure that solution is not polluted to satisfy the quality of water requirement of solution.
