The sealing and lubricating principle of the invention is as follows: as shown in fig. 4, the barb seal structure and the mechanical seal structure of the present invention enable efficient sealing of the piston rod body 23. Wherein, all there is lubricating liquid in barb seal structure and the mechanical seal structure, when the piston rod moved to the right, upwards aspirate disinfectant, membrane piece 31 can be extruded to the disinfectant in the first passageway 6, membrane piece 31 transmits the lubricating liquid in pressure transmission third passageway 29, lubricating liquid transmits pressure to sixth passageway 33 and arrives seventh passageway 34 again, pressure is in turn acted on ejector pad boss 38, make ejector pad boss 38 and lug 35 and barb ring 36 move to the left, because barb ring 36 lower extreme is first to contact with the lantern ring 46 of cover on piston rod body 23, consequently barb ring 36 can be sealed tighter with lantern ring 46 when moving to the left, sealed effect is better. Meanwhile, the pressure at the third channel 29 is also transmitted to the fifth channel 39 and then transmitted to the chamber where the second sealing structure 42 is located to lubricate the second sealing structure 42, because the source of the pressure at the third channel 29 comes from the impact of the medium in the first channel 6 on the diaphragm sheet 31, and the medium in the first channel 6 is periodically conveyed, when the medium has large impact on the diaphragm sheet 31, the lubrication of the second sealing structure 42 is more sufficient, so that the lubrication effect is better, and the chamber of the first sealing structure 41 is lubricated by the self-contained lubricating oil. When the piston rod moves to the left, the lantern ring 46 on the piston rod also moves to the left, so that the fourth channel 30 forms negative pressure, the barb ring 36 and the convex block 35 are sucked, the barb ring 36 abuts against the lantern ring 46, sealing is strengthened, the barb ring 36 and the convex block 35 are elastic, and in the reciprocating process of the piston rod, the barb ring 36 and the convex block 35 are also sealed one by one.

The internal pressure adjusting process of the present invention: lubricating oil is arranged outside the first telescopic diaphragm pipe 15 and in the third chamber 9, when the piston rod moves leftwards, the pressure of the chamber where the first telescopic diaphragm pipe 15 is located is increased, the lubricating oil is extruded into the second channel 27, the lubricating oil enters the fifth chamber 25 through the second channel 27 to extrude the sealing diaphragm bag 26, the sealing diaphragm bag 26 is pushed to move rightwards, and the lubricating oil on the right side of the fifth chamber 25 is pushed to the third chamber 9 by the sealing diaphragm bag 26; conversely, when the piston rod moves to the right, the sealing diaphragm bag 26 moves to the left, so that the lubricating oil on the left side of the fifth chamber 25 moves to the chamber where the first telescopic diaphragm pipe 15 is located through the second channel 27, and the steps are repeated in this way, and pressure balance is realized.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
