Instantaneous Heater for a Smoke Generator

Abstract

An instantaneous heater for a smoke generator includes a heating rod having first and second sections. The second section is connected to a power supply system of a smoke generator. An outer tube is mounted around the heating rod. An end cap is sealing mounted to a first end of the outer tube and covers the first section of the heating rod. The outer periphery of the heating rod, the inner periphery of the outer tube, the end cap, and the connection cap together defines a heating passage intercommunicating with an outlet of the end cap. A connection cap is sealingly mounted around a second end of the outer tube. The connection cap includes a coupling hole intercommunicating with the heating passage. A guiding tube is mounted between the coupling hole of the connection cap and an oil tank of the smoke generator.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a heater for a smoke generator and, more particularly, to an instantaneous heater for heating and vaporizing an oil in a smoke generator into smoke.[0002]A smoke generator for providing a stage performance effect generally heats and vaporizes an oil in the smoke generator into smoke, and the smoke is ejected to the outside to provide a smoke effect on the stage. A conventional smoke generator includes a heating rod wound around by a helical tube made of heat conducting material. An end of the helical tube is coupled to a pump connected to an oil tank. The heat generated by the heating rod is transmitted to the helical tube. The oil in the helical tube is heated and vaporized into smoke which is ejected outwards from the other end of the helical tube. The helical tube can increase the heating time of the oil to assure reliable vaporization of the oil into smoke.[0003]However, the smoke generator requires a longer perio...

AI Technical Summary

Benefits of technology

The smoke generator described in this patent has several technical issues. Firstly, it takes a longer time to preheat because the oil is heated indirectly. Secondly, the contact area between the helical tube and the outside is relatively large, which causes heat to dissipate quickly. To address this, a thermal insulating mechanism needs to be provided to the outer side of the helical tube. Another issue is that the smoke generator cannot operate continuously for a long period of time because its vaporization speed is not fast enough. Lastly, when the smoke generator is not generating smoke, it must keep a standby mode for maintaining the temperature, which causes the heating rod to require intermittent heating to keep the helical tube at a certain temperature for timely providing the smoke. This results in damaged associated electronic components and increased risk of overheating. Additionally, more electricity is consumed in keeping the heating state of the heating rod.

Problems solved by technology

However, the smoke generator requires a longer period of time for preheating, because the oil is indirectly heated.

Furthermore, the contact area between the helical tube and the outside is relatively large, such that most of the heat dissipates rapidly.

Furthermore, the smoke generator cannot continuously operate for a long period of time, because the vaporization speed of the smoke generator is not fast enough due to the indirect heating.

Furthermore, more electricity is consumed in keeping the heating state of the heating rod.
