In order to clearly understand the technical content of the present invention, the following embodiments are specifically mentioned.

Fig. 1 is a schematic structural view and a sectional view of a first embodiment of the present invention, and the pipe line control apparatus of the present invention includes a piston member, a mounting member 3, and a spring 6; the piston component comprises a plastic piston shaft 2 and a plastic cap 1, the plastic piston shaft 2 is a plastic shaft, a through hole 7 is formed in the shaft body, a protruding part 10 is arranged at the end part of the shaft body, the protruding part 10 is a hollow cylinder with the diameter larger than that of the plastic piston shaft, and a cavity is formed in the lower part of the plastic piston shaft 2; the plastic cap 1 is a plastic cap, and the plastic cap 1 is connected with the plastic piston shaft 2 by a buckle; the mounting part 3 is a plastic part, the mounting part 3 is a hollow cylinder with an opening at the upper end, a plastic piston shaft fixing position is arranged in the mounting part, the plastic piston shaft fixing position is connected to the lower end of the cylinder, the fixing position is a cylindrical hollow boss, the lower end of the boss is provided with an opening with the same diameter as that of the cylinder, and the upper end of the boss is provided with an opening with the same diameter as that of the upper part of the plastic piston shaft 2; the spring penetrates through the plastic piston shaft 2 and is arranged between the plastic cover cap 1 and the mounting part 3.

The attachment member 3 is fixed to the endoscope operation portion and is used for attaching and fixing the piston member.

One end of the spring 6 is abutted to the plastic cap 1, and the other end is abutted to the lower surface of the inner cavity of the mounting part 3, namely, the spring 6 is erected between the plastic cap 1 and the mounting part 3 along the direction of the plastic piston shaft 2. The spring 6 biases the piston member upward with respect to the mounting member 3. That is, in a state where the pipe passage control device is not operated by the operator, the piston member is positioned at a position where the mounting member 3 protrudes upward as shown in fig. 1 by the spring 6. At this time, the through hole 7 is in a closed state, and a gap is formed between the piston member and the mounting member 2. When the operator pushes the piston member down against the urging force of the spring 6 until the lower end of the plastic cap 1 abuts against the lower wall of the inner cavity of the mounting member 3, the through hole 7 in the plastic piston shaft 2 is released from the closed state. The endoscope suction pipe is communicated with the through hole 7 and the cavity at the lower part of the plastic piston shaft 2, so that at least one of solid and fluid in the detected body can be sucked. At this time, the plastic cap 1 fills the gap in the mounting part 3 by being pressed down.

Fig. 2 is an assembly diagram of the plastic cap according to the first embodiment, fig. 5 is an assembly diagram of the plastic cap according to the first embodiment, and as shown in fig. 2 and 5, a protrusion 8 is disposed on the top of the plastic piston shaft 2; the plastic cap 1 is a round bottle cap, the top end inside the plastic cap 1 is connected with a hollow cylinder, the cylinder is provided with 3 vertical empty grooves 9 perpendicular to the diameter of the plastic cap, and the width of the empty grooves 9 is the same as that of the bumps 8; the convex block 8 can be inserted into the vertical empty groove 8, the plastic cap 1 is fixed above the plastic piston shaft 2, and the convex block 8 can prevent the plastic cap and the button rod from rotating to influence the function when the plastic cap is pressed into the button rod.

As shown in fig. 2, the boss 4 is provided on the plastic piston shaft, and the boss 4 increases the width of the plastic piston shaft 2, so that the size of the empty groove on the plastic piston shaft 2 can be increased to increase the air intake amount, and the empty groove can be provided as the through hole 7 or other shapes. When the boss 4 is vertical at two sides and is arc-shaped at the upper end and the lower end, the protruding part 10 at the end of the plastic piston shaft 2 needs to be provided with the O-shaped ring 5 for matching use so as to meet the requirement of air inflow.

As shown in FIG. 3, the structure of the second embodiment is schematically illustrated, the side surface of the boss 4 is an inclined surface as shown in the figure, and the cross section is fan-shaped, so that the boss 4 and the piston insertion hole of the cylinder part in the endoscope can have larger contact area, the sealing effect is improved, and the sealing requirement can be met without arranging an O-shaped ring 5 at the end part of the plastic piston shaft 2 in the embodiment.

The boss 4 provided on the plastic piston shaft 2 can increase the diameter of the plastic piston shaft 2, and further increase the size of the through hole 7 to increase the air intake amount.
