Abstract

A fog effects system includes a control system, a fog fluid reservoir, an elongated insulator, an elongated electric heating element, an air supply subsystem, a fog fluid supply subsystem, and a handheld body. The control system can include a battery-operated power supply and a user-operable control. The heating element extends along the insulator. The control system electrically energizes the heating element during system operation. The air supply subsystem directs a flow of air along the heating element during system operation. The fog fluid supply supplies fog fluid to the flow of air. The heating element vaporizes the fog fluid, which is emitted from an end of the system.

Claims (27)

1. A fog effects system, comprising:

a control system including a battery-operated power supply and a user-operable control, the control system initiating at least a portion of system operation in response to the user-operated control;

a fog fluid reservoir;

an elongated insulator;

an elongated electric heating element extending along the insulator and coupled to the control system, the heating element having an intake end and an exhaust end, the control system electrically energizing the heating element during system operation;

an air supply subsystem coupled to the control system, the air supply subsystem directing a flow of air along the heating element from the intake end toward the exhaust end during system operation;

a fog fluid supply subsystem coupled to the fog fluid reservoir and the control system, the fog fluid supply subsystem supplying, during system operation, fog fluid to the flow of air before the flow of air enters the intake of the heating element; and

a handheld body having an opening substantially adjacent to the exhaust end of the heating element, the handheld body containing the battery-operated power supply, the fog fluid reservoir, the insulator, the heating element, the air supply subsystem, and the fog fluid supply subsystem.

2. The fog effects system claimed in claim 1 , wherein:

the insulator is tubular and ceramic; and

the heating element extends within the insulator.

3. The fog effects system claimed in claim 2 , wherein:

the air supply subsystem comprises an air pump coupled to the control system, the control system energizing the air pump in response to the user-operable switch.

4. The fog effects system claimed in claim 3 , wherein:

the fog fluid supply subsystem comprises a liquid pump coupled to the control system, the control system energizing both the air pump and the liquid pump in response to the user-operable switch.

5. The fog effects system claimed in claim 4 , wherein the air pump is a diaphragm pump.

6. The fog effects system claimed in claim 4 , wherein the liquid pump is a peristaltic pump.

7. The fog effects system claimed in claim 1 , further comprising:

at least one electrical lighting element substantially adjacent the exhaust end of the heating element and oriented to illuminate fog emanating from the opening; and

a lighting controller, the lighting controller controlling operation of the electrical lighting element.

8. The fog effects system claimed in claim 7 , wherein the electrical lighting element emits a color resembling a color of fire.

9. The fog effects system claimed in claim 7 , wherein the lighting controller is coupled to the electrical lighting element emits a color resembling a color of fire.

10. The fog effects system claimed in claim 7 , wherein the lighting controller is coupled to the control system, the control system causing the lighting controller to electrically energize the heating element during system operation.

11. The fog effects system claimed in claim 1 , wherein the body is substantially elongated and resembles an object that characteristically burns.

12. The fog effects system claimed in claim 11 , wherein the body resembles a torch.

13. The fog effects system claimed in claim 11 , wherein the body resembles a cigar.

14. The fog effects system claimed in claim 11 , wherein the user-operated control comprises a switch mounted in the body in a trigger-like position relative to a grip portion of the body.
