Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below with reference to Fig. 1 to Fig. 3 to this
Embodiment of the invention for lung to deliver spraying atomization pressurizing device is described further.
As shown in Figure 1, simultaneously referring to Fig. 2 to Fig. 3 it is found that delivering spraying atomization pressurizing device for lung includes cylinder 5, gas
Cylinder 5 is connected with control air valve 8 and air pump 9 in turn, and cylinder 5 includes cylinder body 51 and push rod 52, and the cylinder body 51 of cylinder 5 is towards push rod 52
Extension end is provided with external screw thread；Delivering spraying atomization pressurizing device for lung further includes connecting cylinder 3, and the both ends of connecting cylinder 3 are equal
It is provided with internal screw thread, connecting cylinder 3 is threadedly coupled with cylinder 5, and push rod 52 is extend into connecting cylinder 3.
Connecting cylinder 3 is connected with lung delivering spraying device 1, specific embodiment backwards to the threaded one end of cylinder 5 are as follows: lung delivering
Spraying device 1 is threaded with connector 10, and connector 10 is threadedly coupled backwards to lung delivering 1 one end of spraying device with connecting cylinder 3,
It includes piston rod 2 that lung, which delivers spraying device 1, and piston rod 2 is extend into connecting cylinder 3.The mode of threaded connection, convenient for lung delivering spray
The disassembly and installation of the atomization pressurizing device 1 and cylinder 5 and connecting cylinder 3 of mist, and be connected firmly, it is shaken in the course of work small.
Through-hole 4 is provided on connecting cylinder 3, through-hole 4 is set as track type or rectangle and through-hole 4 is along 3 length direction of connecting cylinder
Extend, the stretching motion of piston rod 2 and push rod 52 is carried out in connecting cylinder 3 and stretched along the length extending direction of connecting cylinder 3
Contracting movement.The length of through-hole 4 is greater than the respective movement travel of piston rod 2 and push rod 52, i.e., push rod 52 and piston rod 2 are in flexible fortune
During dynamic, at through-hole 4, i.e., the length of through-hole 4 stretches out the lung delivering spraying device 1 most greater than the piston rod 2
Long length, and when the piston rod 2 stretches out most short lung delivering spraying device 1 and longest, the piston rod 2 is respectively positioned on described
At through-hole 3, experimenter can be observed and be operated by through-hole 4.
In addition, connecting cylinder 3 is carved with scale 7 in the edge of through-hole 4, scale 7 is extended along the length direction of through-hole 4,
Experiment operator can pull piston rod 2 to the position of suitable scale 7 according to experiment demand, thus adjustable spraying amount.
Reset spring 12, the center line of reset spring 12 and the centerline collineation of cylinder body 51 are fixedly installed in cylinder body 51,
