The invention described above install and use and do flowing mode, extremely shown in Figure 15 as Fig. 9 and Figure 12, at first, be chosen on arbitrary fragment position of outlet pipe 5 and cut off, and form two sections outlet pipe 5a and 5b (as shown in Figure 9), again with the two terminal mouths of pipe of body 50 respectively the application of force fill in these two sections outlet pipe 5a and the 5b, promptly finish assembling (as shown in figure 13) with portable pressure water jet; When not containing air A among the water under high pressure W ' in the delivery port 12 of diaphragm booster pump 10, because of the pressure of water under high pressure W ' elastic force greater than compression spring 80, therefore enter the interior water under high pressure W ' of outlet pipe 5b through delivery port 12, meeting is entered in the hollow exhaust chamber 54 of exhaust seat 52 by the blow vent 56 of the body inside 51 of body 50, and force in synchronously on the bottom 91 of movable pushing block 90, and the taper seat top 92 complete pushing tows of whole movable pushing block 90 are gone in the gas channel 62 of outer cage 60, simultaneously to this gas channel 62 and round recessed 63 mutually junction whole go into the state that interruption-forming is close to fully, and the function that produces leak-stopping is (because of the soft material of movable pushing block 90 has elasticity, produce the effect that prevents seepage so can fit tightly the back mutually) with the outer cage 60 of rigidity material, and then force the former water under high pressure W ' that enters in the hollow exhaust chamber 54 can't enter in the gas channel 62 again, so all water under high pressure W ' all can all arrive water pistol 1 (shown in the solid arrow Figure 13 and the zoomed-in view thereof) from body 50 bodys inner 51 toward the output of another outlet pipe 5a direction, promptly are the states of normal supercharging draining under this start situation.

When being mingled with in the water under high pressure W ' when containing air A, can make the pressure of water under high pressure W ' descend and cause compressing the elastic force of spring 80 on the contrary greater than water under high pressure W ', this moment is under the elastic force effect of this compression spring 80, can make movable pushing block 90 move toward bottom surface 55 directions of hollow exhaust chamber 54, and make itself and gas channel 62 closely connected no longer mutually and be formed with the space between the two, at this moment, contained air A just can be by entering behind the blow vent 56 in the hollow exhaust chamber 54 in the water under high pressure W ', and along the top 92 of movable pushing block 90 space between pierce compressed spring 80 each coil spring and entering in the gas channel 62 again, by steam vent 61 air A is given off outer cage 60 outer (shown in the guided direction of each dotted arrow among Figure 14 and the figure thereof) at last, so it has the effect of exhaust; After treating that all air A all are discharged from outer cage 60, because of the pressure of water under high pressure W ' again once again greater than the elastic force of compression spring 80, so the taper seat top 92 of movable pushing block 90 also can be gone in the gas channel 62 of outer cage 60 by complete pushing tow once again, and again make the whole of gas channel 62 go into the state that interruption-forming is close to fully, and the state (as shown in figure 13) when reverting back to the normal supercharging draining.

When diaphragm booster pump 10 is in when not being activated, be compressed because of movable pushing block 90 under the elastic force effect of spring 80, can make the socle 93 of its bottom on 91 support is affixed on the bottom surface 55 of this hollow exhaust chamber 54, and with the blow vent 56 of body 50 body inside 51 between be spaced apart out one section distance (as shown in figure 12) that equates with the height of this socle 93, contain air A and after starting diaphragm booster pump 10 if be mingled with in the water under high pressure W ' this moment, though the pressure of water under high pressure W ' because of be mingled with contain air A descend cause less than the compression spring 80 elastic force, but be mingled with the air A that contains in the water under high pressure W ', still can directly enter in the hollow exhaust chamber 54 via the space of 93 of each socles of movable pushing block 90 bottoms 91, and along the top 92 of movable pushing block 90 space between pierce compressed spring 80 each coil spring and entering in the gas channel 62 again, by steam vent 61 air A is given off outer cage 60 outer (shown in the guided direction of each dotted arrow among Figure 15) again at last, so under this situation, still have the effect of exhaust, and can not take place air A can't be from body 50 blow vent 56 of exhaust seat 52 bottom surfaces 53 phenomenon of discharging; Therefore, contain air A no matter whether be mingled with in the water under high pressure W ' that the present invention's diaphragm booster pump 10 is exported, it all can reach the function of complete exhaust.

Figure 16 is to shown in Figure 20 for another example, wherein, variable and the groove 903 that concaves and be set as several mutual cross arrangements of the planar base 901 of this activity pushing block 900, after making it be placed on the bottom surface 55 of hollow exhaust chamber 54, still can and the blow vent 56 of body 50 body inside 51 between form the non-state that fits tightly; So when being mingled with in the water under high pressure W ' when containing air A, this air A just can directly enter in the hollow exhaust chamber 54 via the space of the bottom land degree of depth of these several grooves 903, and along the top 902 of movable pushing block 900 space between pierce compressed spring 80 each coil spring and entering in the gas channel 62 again, by steam vent 61 air A is given off outer cage 60 outer (as shown in figure 19) again at last, so it still has the effect of exhaust; After treating that all air A all are discharged from outer cage 60, because of the pressure of water under high pressure W ' again once again greater than the elastic force of compression spring 80, so the taper seat top 902 of movable pushing block 900 also can be gone in the gas channel 62 of outer cage 60 by complete pushing tow once again, and again make the whole of gas channel 62 go into the state that interruption-forming is close to fully, and the state (as shown in figure 20) when reverting back to the normal supercharging draining.

And for example shown in Figure 21, wherein, the outer peripheral edges face of two terminal bodys of this body 50, variablely establish the inclined-plane flange 57 that tool becomes several to be arranged in parallel continuously, and the external diameter yardstick of this inclined-plane flange 57 approximates the bore yardstick of

outlet pipe

5a and 5b, make when

outlet pipe

5a and 5b are placed on this inclined-plane flange 25, can produce the effect of more mutual tight binding and reach complete adeciduate effect.

For another Figure 22 and shown in Figure 23, wherein, steam vent 601 that should outer cage 600 is variable in addition to be set as that both are the configuration of 90 degree angles and perforation mutually again mutually with its gas channel 602, so can make and be mingled with the air A that contains in the water under high pressure W ', direction-agile when discharging outer cage 600 changes into another angle (as shown in figure 23), and can avoid this air A and the aqueous vapor of carrying secretly directly impact touch other member of portable pressure water jet inside.

Continuous extremely shown in Figure 26 as Figure 24, wherein, this activity pushing block 910 is variable again to be set as by hard plastics one ejection formation, and increase in addition in the round recessed 63 of cage 60 outside and plug into a sealed circular ring 70 of being made by elastic rubber material is arranged, and the internal diameter yardstick of sealing annulus 70 is greater than the external diameter yardstick of compression spring 80, but its external diameter yardstick then is slightly larger than the internal diameter yardstick of round recessed 63, so that behind the round recessed 63 of cage 60, it can form tightness cooperation (Interference fit) between the two and can not come off outside filling in; When being mingled with in the water under high pressure W ' when containing air A, this air A can directly enter in the hollow exhaust chamber 54 via the space of 913 of each socles of movable pushing block 910 bottoms 911, and along the top 912 of movable pushing block 910 space between pierce compressed spring 80 each coil spring and entering in the gas channel 62 again, by steam vent 61 air A is given off outer cage 60 outer (as shown in figure 25) again at last, so it also has the effect of exhaust; After treating that all air A all are discharged from outer cage 60, because of the pressure of water under high pressure W ' again once again greater than the elastic force of compression spring 80, so sealed circular ring 70 promptly can be touched by pushing tow in the taper seat top 912 of movable pushing block 910, and the state that forces formation between the two to be close to fully, and then stop water under high pressure W ' can't enter in the gas channel 62, the state (as shown in figure 26) when therefore reverting back to the normal supercharging draining again.

Extremely shown in Figure 29 as Figure 27, wherein, central interior that should outer cage 610 by end face to the bottom surface direction, can change in regular turn respectively and be set as a steam vent 611, one gas channel 612 and a hollow exhaust chamber 613, and the outer peripheral edges face of its lower semisection is provided with pin thread 614, wherein, this steam vent 611 connects mutually with this gas channel 612, and this gas channel 612 connects mutually with this hollow exhaust chamber 613, and the internal diameter yardstick of this hollow exhaust chamber 613 is greater than the internal diameter yardstick of gas channel 62, and can insert for movable pushing block 90, and the internal diameter yardstick of this gas channel 62 is greater than the aperture yardstick of this steam vent 61, cooperate exhaust seat 512 central end faces change downwards to be set as recessed circular groove 513 in addition simultaneously, and on its trough wall surface, be provided with negative thread 514, it can be screwed with the pin thread 614 of outer cage 610 this body 510.Is as Figure 28 and shown in Figure 29 as for its exhaust as flowing mode, when being mingled with in the water under high pressure W ' when containing air A, this air A can directly enter in the hollow exhaust chamber 613 of outer cage 610 via the space of 93 of each socles of movable pushing block 90 bottoms 91, and along the top 92 of movable pushing block 90 space between pierce compressed spring 80 each coil spring and entering in the gas channel 612 again, by steam vent 611 air A is given off outer cage 610 outer (as shown in figure 28) again at last, so it still has the effect of exhaust; After treating that all air A all are discharged from outer cage 610, because of the pressure of water under high pressure W ' again once again greater than the elastic force of compression spring 80, so the taper seat top 92 of movable pushing block 90 promptly can be gone in the gas channel 612 of outer cage 610 by complete pushing tow once again, and again make the whole of gas channel 612 go into the state that interruption-forming is close to fully, and the state (as shown in figure 29) when reverting back to the normal supercharging draining.
