Description

Smoke machine

The present invention relates to a fog machine.

Generally used in theaters, stage and other performance occasions, how much will require the special effects of smoke, and this effect can not be replaced by ordinary dry ice vaporization, at this time can not immediately take the item to burn to produce smoke. Therefore, some manufacturers have developed a smoke machine that introduces smoke oil into a conduit and simultaneously heats the smoke oil in the conduit with the electric heating rod, so that the smoke oil is gradually vaporized into smoke and discharged to the outside, such as TWM451175 and TWM492783. This is the type of smoke machine that is exposed.

However, in the above-mentioned conventional smoke machine, the smoke naturally spreads along the duct to the outside, in other words, the smoke slowly advances rather than quickly discharges the duct; and when the smoke oil is converted from a liquid to a gas, it is in a small duct. In progress, as a result, the smoke oil in the conduit will be less than ideal in the vaporization transition process. Not only does the user not be able to get the required smoke more immediately, but also the discharge of the vaporized oil that is not completely vaporized will cause pollution of the surrounding environment or cause a fire. It is clear from the above that the conventional smoke machine exists. Need to improve the shortcomings.

Therefore, it is necessary to provide a novel and progressive smoke machine to solve the above problems.

The main object of the present invention is to provide a fog machine which can quickly discharge smoke to the outside for the operator to use, thereby ensuring that the internal smoke oil has sufficient space for vaporization, thereby protecting the safety of the operator and the surrounding environment. clean.

More preferably, the oil supply portion 25 is in a communication tube relationship with the oil reservoir 24, and a see-through block 251 is disposed in the oil supply portion 25, so that the operator only needs to observe the perspective block 251. The liquid level of the smoke oil A can clearly and quickly know the amount of oil of the smoke oil A remaining in the oil reservoir 24.

Next, the gas C is further described. Generally, the gas C is selected from a compressed high-pressure gas source, so that the vacuum generator 33 can generate a better suction force, which is not limited thereto, and may be required according to circumstances. change. Preferably, the airflow system 3 is further provided with a pressure regulating valve 34. The pressure regulating valve 34 is disposed in the inlet flow channel 31 and located before the vacuum generator 33. The pressure regulating valve 34 can adjust the incoming gas C. The pressure is to comply with the safe pressure value of the smoke machine 1 or to meet the pressure required at present; in addition, the pressure regulating valve 34 can also have a voltage stabilizing function, so that when entering the vacuum generator 33 The pressure of the gas C can be kept consistent, and a stable negative pressure suction can be generated.
