The inside top of head cap 1 has the first convex clip 13 around channel spacing arrangement, corresponding, the top of piston rod 5 with it is upper
The second convex clip 56 that the first convex clip 13 is engaged is stated, under connection completion statuses, the phase that the first convex clip 13 is spaced with the second convex clip 56
Mutually clamping is so that 1 rotational band piston bar 5 of head cap is rotated.
, when dispatching from the factory, head cap 1 is in compression lock-out state, the i.e. projection of 5 periphery of piston rod for emulsion pumps in the present embodiment
In 51 positioning ports 41 for snapping in 4 bottom of lock tube, as shown in Figure 5；It is fully compressed under lock-out state in head cap 1,44 upper end of inner sleeve
Medial surface just with protuberance 57 tight against so as to sealing formed here, to prevent the liquid in bottle from the pump housing 3
Air inlet 38 leaks into outside in extrusion chamber 30 and further by the space between piston rod 5 and lock tube 4 upwards.Use
When, rotate head cap 1, make projection 51 depart from positioning port 41 turn in chute 42, now, piston rod 5 under the elastic force of spring 6 to
Upper movement, so that head cap 1 is in released state, as shown in fig. 6, and now the upper end of piston 8 is offseted with 44 lower end of inner sleeve, work
Sealing state is between plug 8 and lock tube 4, as shown in a parts in Fig. 6.Head cap 1 is pressed with handss, 1 stress of head cap is moved downward,
Head cap 1 and piston rod 5, piston seat 7 are fitted together, and three can be considered as single type, are acted on by 1 pressing force of head cap, 1 He of head cap
Piston rod 5, piston seat 7 are moved downwardly together, and due to there is frictional force between piston 8 and the pump housing 3, piston 8 occurs phase with piston seat 7
To motion, piston 8 is separated with the collet 71 of 7 bottom of piston seat, forms gap between the two, when 8 upper end relative movement of piston is arrived
When offseting with 5 bottom of piston rod, head cap 1, piston rod 5, piston seat 7, piston 8 four are just moved downwardly together, as shown in Figure 7；
Continue pressing head cap 1, spring 6 is compressed, due to hoodle 9 and 3 fitted seal of the pump housing, now the air in the pump housing 3 is just along work
Gap between plug 8 and piston seat 7 is entered in piston rod 5 by the through hole 72 on piston seat 7, runner 70 and passes through 1 row of head cap
Go out, as shown in Figure 8.When handss unclamp head cap 1, now there is no the effect of downward force on head cap 1, acted on by 6 elastic force of spring, piston
Seat 7, piston rod 5 and head cap 1 are moved upwards, and due to there is frictional force between piston 8 and the pump housing 3, piston 8 is occurred with piston seat 7
Relative motion, 8 lower end of piston are returned to again and are offseted state with the collet 71 of piston seat 7, now between piston 8 and piston seat 7
Sealing is seamless, as shown in Figure 9；Piston seat 7, piston rod 5, piston 8 and head cap 1 are continued up, and are acted on by atmospheric pressure, bottle
Interior liquid is inhaled in the pump housing 3, and now gap of the gas outside the pump housing 3 along between lock tube 4 and piston rod 5 passes through the pump housing
Air inlet 38 in the middle of 3 is entered in bottle, and so on, and the liquid in bottle is constantly discharged from the pump housing 3, as shown in Figure 8.No
Used time, head cap 1 is rotated along 1 upward arrow rightabout of head cap, drive piston rod 5 to rotate, when projection 51 and lock tube on piston rod 5
After the chuck 431 on 4 tops is mutually blocked, head cap 1 is limited, it is impossible to push.
