Impact type diaphragm micro jet dispensing device

The invention relates to dispensing devices, particularly to an impact type diaphragm micro jet dispensing device which comprises an air cylinder, a gland, a stroke adjustment lever, a piston rod, springs, a jet chamber, a diaphragm, a nozzle and a high-frequency electromagnetic valve, wherein the gland is mounted above the air cylinder; the stroke adjustment lever is mounted in the gland through screw threads; the piston rod is arranged in the air cylinder; the springs are arranged between the gland and the piston rod, and are pressed on the upper end surface of the piston rod; the piston rod is positioned below the stroke adjustment lever; the jet chamber is mounted below the air cylinder; the diaphragm is mounted between the jet chamber and the air cylinder in a clamping manner, and is positioned below the piston rod; the nozzle is mounted on the lower end surface of the jet chamber; and the high-frequency electromagnetic valve is communicated with the air cylinder. According to the impact type diaphragm micro jet dispensing device, the impact force of the piston rod is transferred to the liquid in the jet chamber through the diaphragm, and the direct contact of the piston rod and the nozzle and the glue liquor is avoided, so that the particles in the glue liquor are not damaged during the jet of the glue liquor containing particles, the severe abrasion of the nozzle is avoided, and the use cost is reduced.
