Fig. 1 d is that one piston assembly 12 is inserted into accommodation box assembly 11 intermediateness sectional drawings.Fig. 1 e is that one piston assembly 12 is inserted into accommodation box assembly 11 end-state sectional drawings.
Referring to Fig. 1 d and Fig. 1 e, one piston assembly 12 is to receiving inner continuation of cylinder 112 to slide, after sleeve 123 contacts with the step of the inwall bottom of receiving cylinder piston 113, the slip step 1231 of sleeve 123 front ends props up the step of receiving cylinder piston 113 bottoms, receiving under the drag effect of step of cylinder piston 113 bottoms, sleeve 123 cannot be with respect to receive a cylinder piston 113 travel forward (but can travel forward) together with receiving cylinder piston 113; Owing to acting on the continuous action of horizontal forward external force of one piston assembly 12, the outer tube 121 of one piston assembly 12 and inner tube 122 with respect to sleeve 123 forward (in figure left direction) mobile, in moving process, the front end of sleeve 123 promotes one piston compression spring 124 and shrinks, until the positioning step 1211 on the outer tube 121 of one piston assembly 12 contacts and cannot continue to move forward with the barrel of receiving cylinder 112.Sleeve 123, with respect to the operation backward of inner tube 122 and the contraction of one piston compression spring 124, makes the spout 1222 of offering in inner tube 122 stretch out described sleeve 123, and now, liquid can flow out from spout.
Meanwhile, when the slip step 1231 of sleeve 123 front ends props up after the step of receiving cylinder piston 113 bottoms, under the lasting External Force Acting of substantially horizontal forward, sleeve 123 and one piston head 1221 promote to receive cylinder piston 113 to travel forward together, referring to Fig. 1 e, this Driving force makes to receive cylinder Compress Spring 114 to shrink, receive cylinder piston head 1131 to be backed down by one piston head 1221, now, receive the liquid entering hole 1332 of offering on cylinder piston wall to extend in the receiving cavity 1111 of box body 111, receive between cylinder piston 113 and one piston assembly 12 and form passage, the spout 1222 of offering in the inner tube 122 of one piston assembly 12 is mated completely or occurs simultaneously along one piston assembly 12 and the direction (substantially horizontal in figure) of receiving cylinder piston 113 to dock with the liquid entering hole 1132 of offering on receiving cylinder piston 113, thereby liquid can flow in the receiving cavity 1111 of box body 111 through above-mentioned liquid entering hole 1132 from spout 1222, realize the conducting of valving.
After liquid has injected, for one piston assembly 12 being extracted to described accommodation box assembly 11, one piston assembly 12 is subject to horizontal external backward.Now, when horizontal external forward fades away and becomes horizontal external backward, under the tension force of receiving cylinder Compress Spring 114 to stretch, and under the drive backward of sleeve 123, and collet head rubber ring on slip step 1,231 125 with receive under the effect of frictional force of cylinder piston bottom rubber ring 116, receive cylinder piston 113 to return to original position, the receiving cylinder piston head rubber ring 115 of piston head 1131 periphery settings presents fit-state again with the inwall of box body 111, realizes the sealing of receiving between cylinder 112 and box body 111.Alternatively, the horizontal external forward or backward that one piston assembly 12 is subject to can be produced by motor.
Simultaneously, under the effect of receiving cylinder Compress Spring 114 and level backward under External Force Acting, one piston head 1221 moves backward, along with receiving the disappearance of resistance of step of cylinder piston 113 bottoms, one piston compression spring 124 starts to stretch, under the elastic force effect of one piston compression spring 124, sleeve 123 moves forward with respect to outer tube 121 and the inner tube 122 of one piston assembly 12, until sleeve 123 covers inner tube 122 therein, and one piston head rubber ring 127 is fitted on the collet head rubber ring 125 of sleeve 123 front-end faces.Afterwards, the slip step 1231 of sleeve 123 front ends just departs from the step of receiving cylinder piston 113 bottoms, and collet head seal ring 125 separates with receiving cylinder piston bottom seal ring 116.
Be pulled out in process at above-mentioned one piston assembly 12, the volume of the passage between spout 1222 and liquid entering hole 1332 is reducing gradually, but sealing channel when valve conducting still exists, , before one piston assembly 12 does not depart from receiving cylinder 112, collet head rubber ring 125 and receiving cylinder piston tail part rubber ring 116 are still in intimate-association state, until one piston assembly 12 is completely pulled out of, spout 1222 is returned to sleeve 123 inside, and one piston head rubber ring 127 is fitted in sleeve 123 front-end faces, now, liquid is pushed back to one piston assembly 12.Thus, after having guaranteed that liquid is fully retrieved to one piston assembly 12 inside, just depart from completely with accommodation box assembly 11, avoided the interior retention liquid of accommodation box assembly 11 and produce the phenomenon of leakage.And, the existence of sleeve tail rubber ring 126, makes between sleeve 123 and outer tube 121 always in sealing state, even if sleeve 123 is in the time stretching into and extract accommodation box assembly 11, carry out motion backward or forward, also can not cause liquid to flow out the outside of one piston assembly 12.
Alternatively, as previously mentioned, on the inner tube 122 tube wall outer walls of one piston assembly 12, can arrange and stretch out muscle 1223, this stretches out muscle 1223 for limiting the position of Compress Spring, for spring provides a support, the length that reduces spring, reduces costs, as shown in Figure 1 f.
