Abstract
A smoke generating apparatus includes a housing having an interior cavity. A heated substrate is disposed within the interior cavity of the housing. A reservoir is provided to hold smoke generating liquid. An atomizing nozzle is disposed within the interior cavity of the housing. The nozzle has an inlet end and an outlet end. The outlet end points toward the heated substrate, such that fluid medium discharged through the outlet of the nozzle strikes the heated substrate. The inlet end of the nozzle is coupled to a source of gas under pressure. A liquid flow passage is provided which connects the nozzle with the reservoir. A flow of gaseous medium through the nozzle atomizes smoke generating liquid drawn from the reservoir.
Claims13
A smoke generating apparatus, comprising:
- a housing having an interior cavity;
- a heated substrate is disposed within the interior cavity of the housing;
- a reservoir;
- an atomizing nozzle disposed within the interior cavity of the housing, the nozzle having an inlet end and an outlet end, with the outlet end pointing toward the heated substrate, the heated substrate surrounding the outlet end of the spray nozzle, such that fluid medium discharged through the outlet of the nozzle strikes the heated substrate;
- means to couple the inlet end of the nozzle to a source of gas under pressure;
- and
- a liquid flow passage connecting the nozzle with the reservoir, such that a flow of gaseous medium through the nozzle atomizes smoke generating liquid drawn from the reservoir via the liquid flow passage.

- means to couple the inlet end of the nozzle to a source of gas under pressure;
- and
- a liquid flow passage connecting the nozzle with the reservoir, such that a flow of gaseous medium through the nozzle atomizes smoke generating liquid drawn from the reservoir via the liquid flow passage;
- a gaseous medium flow passage being provided through the nozzle, the flow passage having an inlet portion and an outlet portion, the outlet portion of the gaseous medium flow passage being divided into at least two branch passages, the sum of the cross-sectional areas of the outlet portions being equal to the cross-sectional area of the inlet portion, the branch passages being positioned adjacent an outlet end of the liquid flow passage and means being provided to deflect the flow of gaseous medium from the branch passages of the gaseous medium flow passage to provide a substantially linear flow through the outlet end of the nozzle;
- and
- means being provided to adjust the relative spacing between the outlet end of the spray nozzle and the heated substrate.
