Preferably, the connecting pipe is a plastic corrugated hose.
Preferably, the cap comprises an outer shell and an inner shell.
Preferably, the distance between the outer and inner shells is not less than 10 mm.
Preferably, the housing is provided with an air inlet, and one end of the connecting pipe is connected with the air inlet.
Preferably, an air volume adjusting valve is arranged on the air inlet.
Preferably, the air curtain outlet comprises an outer side wall and an inner side wall, the outer side wall is connected with the outer shell, and the inner side wall is connected with the inner shell.
Preferably, a horizontal visor is further provided on the outer shell at the leading edge of the cap body.
Preferably, the outer side wall is perpendicular to the visor, and an included angle of 5-15 degrees is formed between the inner side wall and the outer side wall.
Preferably, the cap body is further provided with a cap belt.
The utility model has the advantages that the structure is simple, the wearing is convenient, the paint mist in the air can be effectively isolated from the user by arranging the air curtain outlet at the front edge of the hollow cap body, and the fresh air is directly sent into the breathing area of the human body, so that the protection effect is better; the protective cap has no contact with the face of a person, the visual field is clear when the protective cap is used, and the operation is not influenced.
