It presses in chamber 32, and is close to the inner wall of pressurizing chamber, one end of drive rod 331 is connect with piston head 332, and the other end extends to pressurizing chamber
32 outside；Screw thread latch is provided on the lateral wall of drive rod 331.Forcing pipe 31 is provided on one end far from pressure rod 33
Inlet 4 and liquid outlet 5；When pressure rod 33 is directed away from the movement of 4 direction of inlet, anesthetic liquid medicine is added by the sucking of inlet 4
It presses in chamber 32；When pressure rod 33 is towards close to the movement of 5 direction of liquid outlet, the anesthetic liquid medicine in pressurizing chamber 32 is sprayed from liquid outlet 5
Out.
The main effect of pressing mechanism is by the anesthetic liquid medicine in liquid storage bottle through feed liquor check valve and inlet sucking pressurization
It is intracavitary, then by the anesthetic liquid medicine in pressurizing chamber through liquid outlet and liquid check valve discharge out.
When pulling upwardly on the drive rod on pressing mechanism, move up piston head along the inner wall of pressurizing chamber, pressurizing chamber
It is at this time in negative pressure, when negative pressure value has been more than the pressure value on feed liquor check valve on inlet, feed liquor check valve is opened, convenient
By the anesthetic liquid medicine in liquid storage bottle through becoming through liquid check valve sucking pressurizing chamber so that the pressure value in pressurizing chamber be made to be gradually increased
It is bordering on zero.
When being pressed downward drive rod, make drive rod that piston head be driven to move down, the air to gradually reduce in pressurizing chamber makes to add
Pressing intracavitary pressure increase is positive pressure, when the pressure in pressurizing chamber is greater than the pressure value on liquid check valve, liquid check valve out
It opens, drive rod continues to move down, and makes the anesthetic liquid medicine in pressurizing chamber gradually by going out the discharge of liquid check valve.
It is boosted to the anesthetic liquid medicine in pressurizing chamber, after acceleration by pressing mechanism, then is sprayed by atomizer, atomizer,
Be conducive to improve atomizing effect, and reciprocal pull, pushing, so that anesthetic liquid medicine continuous uniform is sprayed, be not in local fiber crops
Liquor-saturated amount non-uniform phenomenon, improves anaesthetic effect.
In order to enable the continuous pull of the pressure rod on pressing mechanism, move back and forth, forcing pipe 31 far from inlet 4 one
Power mechanism 11 is provided on end, power mechanism provides circulation power for the reciprocating motion of pressure rod.Power mechanism 11 includes
