Abstract: A water tank mounting structure and a ventilation treatment apparatus for such structure. The water tank mounting structure comprises a cavity for containing a water tank and a side wall defining the cavity, wherein the side wall comprises an inner side wall spaced apart from an outer side, a first gas hole provided in the inner side wall, and a second gas hole provided in the outer side wall, both holes arranged in a staggered manner perpendicular to the side wall. The arrangement of the double-layer side wall, and the first and second gas holes in the inner and outer side walls, respectively, allows for hot gas in the cavity to be effectively removed. The staggered arrangement of the gas holes allows for water to flow downward along the side wall without invading the cavity when water enters through the second gas hole. A waterproof effect is achieved.

Abstract: A humidification tank and a ventilation treatment device are provided. The humidification tank includes a tank body having a cavity, a connector pipe inserted into the cavity, and at least two branch pipes communicated with an outlet end of the connector pipe. The branch pipes can provide airflow towards different directions so that gas reaches more positions in the cavity, the existence of a position to which the gas cannot be blown in the cavity is avoided, the occurrence of a dead zone of airflow is avoided. The fluidity of gas inside the cavity is improved, and a gas flowing path is lengthened, thus improving the humidifying effect of gas.
