Furthermore, the air guide channel takes the central axis of the exhaust adjusting pipe as the center and is spiral, and the air inlet small holes are in one-to-one correspondence with the intervals between the spiral sections of the air guide channel. Therefore, the flowing time of the discharged steam in the air guide channel can be prolonged, the condensation effect on the steam is improved, and the amount of the discharged steam is reduced.
Further, the exhaust adjusting pipe is obliquely arranged, the distance between the spiral sections of the air guide channel increases progressively from bottom to top along the length direction of the exhaust adjusting pipe, and correspondingly, the aperture of the air inlet small hole also increases progressively from bottom to top along the length direction of the exhaust adjusting pipe.

Furthermore, the lower end of the air guide channel is provided with a water flowing hole communicated with the inner cavity of the exhaust adjusting pipe. Therefore, condensed water in the air guide channel can flow into the exhaust adjusting pipe through the water flowing hole, then flows back to the inner container from the exhaust port of the inner container through the exhaust adjusting pipe, and is heated and evaporated into steam through the heating plate in the inner container, so that the cyclic utilization of the condensed water is realized.
