In addition, the arrangement of the sub-chamber 1914 can increase the heat exchange area between the steam and the inner wall of the chamber, and can further improve the condensation effect.

As shown in fig. 6 and 7, the steam entering from the inlet 1913 gradually disperses into the sub-chambers 1914, and the condensed water formed after condensation converges and is discharged from the inlet 1913 into the exhaust pipe 16, and then flows back into the liner.

As shown in fig. 7, the end cap 192 is formed with a protrusion (not shown) that can be fitted into each sub-chamber 1914, and the connection between the end cap 192 and the main body portion 191 is achieved by interference fit of the protrusion with the inner wall surface of the condensation chamber. To further improve the tightness of the condensation device 19, the end cover 192 and the main body 191 may also be connected by gluing.

It can be understood that the device body can also be made into a structure which is buckled up and down.
