In the use process, the air extraction cylinder 113 is continuously deformed by continuously extruding the air extraction cylinder 113, when the air extraction cylinder 113 is extruded, the volume of the air extraction cylinder 113 is reduced, the internal pressure is increased, at the moment, the air pressure of the first one-way valve towards the air outlet 307 is smaller than the air pressure of the first one-way valve towards the air extraction cylinder 113, so that the first one-way valve is closed, at the moment, the air pressure of the second one-way valve towards the air extraction cylinder 113 is larger than the air pressure of the second one-way valve towards the air ventilation cylinder 112, so that the second one-way valve is opened, the air in the air extraction cylinder 113 is discharged into the air ventilation cylinder 112, the air pressure of the blocking ball 114 close to the air extraction cylinder 113 is increased, and further, when the pressure difference of the two sides of the blocking ball 114 is larger than the gravity of the blocking ball 114, the blocking ball 114 can slide upwards along the air ventilation cylinder 112 under the pushing of the air; when the air suction cylinder 113 recovers under the self elastic action, the volume of the air suction cylinder 113 is increased, the internal pressure is reduced, the air pressure of the first one-way valve towards the air outlet 307 is larger than the air pressure of the first one-way valve towards the air suction cylinder 113, the first one-way valve is opened under the action of pressure difference, the air suction cylinder 113 sucks the air in the ink guide tube 400 and the built-in ink box 300, and the air pressure of the second one-way valve towards the air suction cylinder 113 is smaller than the air pressure of the second one-way valve towards the air ventilation cylinder 112, so that the second one-way valve is closed.
And because the preset gap is arranged between the blocking ball 114 and the inner peripheral wall of the ventilation cylinder 112, the gas on the side, close to the air suction cylinder 113, of the blocking ball 114 can slowly pass through the preset gap and then is discharged to the external environment from the vent hole 1121, so that the air pressure on the side, close to the air suction cylinder 113, of the blocking ball 114 is reduced, and when the pressure difference on the two sides of the blocking ball 114 is smaller than the gravity of the blocking ball 114, the blocking ball 114 slides downwards to an initial position along the ventilation cylinder 112 under the action of the gravity of the blocking ball.
When ink is still in the external ink box 200, the air in the ink guide tube 400 and the internal ink box 300 can be sucked by continuously extruding the air suction tube 113, so that on one hand, the redundant air in the ink guide tube 400 and the internal ink box 300 can be discharged, and on the other hand, the ink level in the ink conveying chamber 302 is raised to drive the floating ball 308 to rise along with the air guide tube, and when the air outlet 307 is blocked by the floating ball 308, the ink still exists in the external ink box 200.
