<Summary of the Invention> The present invention relates to a portable air brushing device in which a nozzle part for spraying high-pressure gas and a high-pressure gas cylinder are integrated with the device body.

<Prior art> Conventionally, ink, paint, etc. are compressed air or high pressure CFC gas,
2. Description of the Related Art An air brushing device for spraying with propane gas or the like to perform drawing is used.

In the conventional air brushing device that uses compressed air, compressed air compressed by an air compressor is supplied into the brushing device main body through an air hose, and this compressed air is sprayed from the tip of the nozzle to It is configured to spray ink and paint.

Further, even in the air brushing device using high pressure gas such as CFC gas or propane gas, the high pressure gas filled in the gas cylinder is supplied into the brushing device main body through the air hose and jetted from the tip of the nozzle so that It is configured to spray ink and paint.

<Problems to be Solved by the Invention> In each of the above-described conventional air brushing devices, an air compressor or a gas cylinder is prepared separately from the nozzle part for spraying compressed air or high-pressure gas, and the above-mentioned compression is performed via an air hose. Since it is configured so that air or the like is sent into the brushing device main body and jetted, the device becomes large and it is difficult to carry and use.

Further, since the air hose extends from the main body of the brushing device, the air hose becomes an obstacle and it is difficult to use in a narrow space, and it is impossible to perform fine brushing work.

Furthermore, in the case of using an air compressor,
This air compressor requires a drive source, making it difficult to use outdoors and handling the equipment. Furthermore, the one using an air compressor cannot be used in a painting room where the noise from the air compressor is extremely quiet.

Therefore, the present invention is intended to provide an air brushing device that can be used by being carried, is easy to handle, and can be easily used even by an infant or the like.

Further, the present invention is intended to provide an air brushing device of extremely high utility, which enables fine work and use in a narrow space.
