US12551819 - Waterproof heating module for smoke generator

A waterproof heating module for a smoke generator comprises a heat exchanger ( 45 ) including an ejection portion ( 115 ) configured to eject smoke. The heat exchanger ( 45 ) is received in an inner side of an outer casing ( 135 ). The ejection portion ( 115 ) extends through a through-hole ( 139 ) of the outer casing ( 135 ) to an outer side of the outer casing ( 135 ). A closure plate ( 155 ) includes a closure face ( 157 ) and a coupling hole ( 159 ) extending through the closure face ( 157 ). The coupling hole ( 159 ) of the closure plate ( 155 ) has an inner periphery ( 160 ) in waterproof coupling with an outer periphery of the ejection portion ( 115 ). The ejection portion ( 115 ) extends out of the closure plate ( 155 ) via the coupling hole ( 159 ). The closure face ( 157 ) of the closure plate ( 155 ) is in waterproof coupling with the through-hole ( 139 ) of the outer casing ( 135 ).
