Cup 20 starts downward stretching.
S3, due to go out liquid drugs injection 31 fixed it is spacing withstand cup 20, the actual length stretched downwards of cup 20 will be direct
The active force for being converted to N/10bar is adjacent to out liquid drugs injection 31, reaches to suppress and is adjacent to sealed effect.
S4, now capsule 2 start from the circular water outlet of apopore 21, and liquid is directly flowed from the inside of capsule 2 by going out liquid drugs injection 31
Into cup.
S5, after the completion of the extraction of capsule 2, open handle 1, the resilience of cup 20 playback after the inside of capsule 2 is lost heart, it is to avoid capsule
2, which block out liquid drugs injection 31, to take out.
Operation principle is as follows：
Using mechanically deform principle, be specially it is following some：
1st, after capsule cleaner handgrip 1 is pressed, enter liquid drugs injection 11 and pierce through capsule 2, while the liquid drugs injection 31 that goes out on retainer 3 pierces through aluminium foil
22；
2nd, raised 26 structure now gone out on liquid drugs injection 31 holds the circular hole side of the bottom circular apopore 21 of cup 20, and whole face
Stress is fitted；
3rd, capsule machine starts to inject hot water to the inside of capsule 2, the constantly savings hydraulic pressure of cup 20, and constantly heated, cup
20 can integral sinkings, sinking action can make the bottom of capsule 2 fitted with the close structure of retainer 3 sealing effectiveness.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, it is every at this
