Ignition device for starting smoke sprayer

Abstract

The invention discloses an ignition device for starting a smoke sprayer. The ignition device for starting the smoke sprayer is characterized by being mounted on the combustion chamber of the smoke sprayer and comprising a power source (1), a power switch (2) and a resistance wire (3). The output end of the power source (1) is connected in parallel with the resistance wire (3), and the power switch (2) is connected in series with the power source (1) and the resistance wire (3). According to the ignition device for the starting the smoke sprayer, during the process of starting the smoke sprayer, the resistance wire heats to ignite fuel mixed air inside the combustion chamber. The ignition device for starting the smoke sprayer overcomes shortcomings existing for a long time, is simple in structure and low in cost and meanwhile achieves simple operation by starting the smoke sprayer through heated ignition of the resistance wire, thereby being capable of greatly improving the success rate in starting the smoke sprayer.

Description

technical field [0001] The present invention relates to the technical field of a liquid injection device for exterminating pests, in particular to an ignition device for starting a smoke machine. Background technique [0002] At present, the fog machine is usually composed of a jet engine and a drug supply system. The jet engine is composed of a combustion chamber, a starting system, a fuel supply system, and an ignition device. The drug supply system is composed of a medicine box, a medicine switch, a medicine outlet, and a pipeline. For a long time, people have prejudice against the start of the fog machine. The prejudice is that the spark plug must be used to ignite the fuel mixture in the combustion chamber to start the smoke machine. After ignition, the mixture in the combustion chamber will burn or "explode" to complete the start of the smoke machine. It has been used until now, and the starting process is: the pressure air generated by the air cylinder (or fan) will f...

AI Technical Summary

Problems solved by technology

[0003] (1) It is difficult for the spark plug of the ignition device to ignite and start the smoke machine. When starting the smoke machine, the gas cylinder (or fan) is used to inflate. Manual operation, the force is inevitably different. If the force is slightly larger when inflating, the fuel tank is pressed out Too much fuel can easily drown the spark plug of the ignition device, which will cause the smoke machine to fail to start;

[0004] (2) The ignition device uses a spark plug to ignite, and the insulator on the spark plug is easy to deposit carbon. Under high voltage, the carbon deposit will cause the spark plug to leak or short circuit, and the spark plug cannot ignite, causing the smoke machine to fail to start;

[0005] (3) The ignition device uses a spark plug to ignite with high environmental requirements. When the ambient humidity is high, the humidity of the mixed gas in the carburetor will increase accordingly, and the spark plug will be easily damp. After being damp, it will be quickly oxidized, the insulation will decrease, and a short circuit will easily occur. Cause the spark plug to fail to ignite, causing the smoke machine to fail to start;

[0006] (4) The ignition device uses a spark plug to ignite, which requires a high-voltage generator to ignite. The insulator of the spark plug must have good insulation, high voltage resistance and high temperature resistance, so the structure is complex and the manufacturing cost is high.

[0007] To sum up, the ignition devices of the existing smoke machines all use spark plugs to start the ignition. The spark plugs are used as the ignition parts of the smoke machines. The success rate of ignition and starting the smoke machine is low
