When remove attracting the pressing of button 44, make lid 26 return the primary importance of initial condition by the elastic-restoring force of lid 26.At the primary importance place, the first valve 60 and second valve 61 are switched, so suction pump 20 links to each other with atmosphere via suction catheter 21, the first valve 60 and passage 56.
Then, the effect about present embodiment describes.When the attraction that do not attract disconnects, as shown in Figure 2, by lid 26 to plunger 25 to the primary importance application of force.At this primary importance place, the first valve 60 becomes out state, and second valve 61 becomes the state of closing.Thus, suction pipeline 17 is blocked, with the be communicated with cut-out of suction pipeline 17 with suction catheter 21, thereby becomes the state that the attraction that comes self-gravitation mouth 15 stops.At this moment, the inner peripheral surface of the periphery wall of second valve section 49 and the second valve seat 35 connects airtight, and plunger 25 is consistent with the central shaft on straight tube road 34 thus.
In addition, suction catheter 21 is via connector 37, straight tube road 34, the first valve 60 and be communicated with passage 56.Thus, suction catheter 21 is communicated with atmosphere, so prevent from suction pump 20 is applied load.
In situation about attracting, as shown in Figure 3, attract button 44 operation that is pressed.By this pressing operation, strains occur in the skirt section of lid 26 51, and plunger 25 moves to the second position from primary importance.At second position place, the first valve 60 becomes the state of closing, and suction catheter 21 was cut off with being communicated with of passage 56 (atmosphere).In addition, second valve 61 becomes out state, and suction pump 20 is communicated with suction pipeline 17.Then, be accompanied by the movement to the second position, cam-follower 46 contacts with cam surface 39, and piston body 41 is 34 interior inclinations on the straight tube road.Because off-centre, the gap enlargement between the outer peripheral face of the inner peripheral surface of the second valve seat 35 and piston body 41 occur in the second valve seat 35 inner plunger main bodys 41 in this inclination.Thereby the negative pressure suction force that reaches in the suction catheter 21 in each pipeline that is communicated with it increases, thereby from attracting mouthful 15 various body fluid of attraction or solids etc.This attracts thing via after the suction pipeline 17, discharges to the outside of endoscope 10 by straight tube road 34 and suction catheter 21.
In the situation that stops to attract, remove for the pressing operation that attracts button 44.Thus, by the restoring force in skirt section 51 and make plunger 25 return primary importance, the first valve becomes out state, and second valve becomes the state of closing, and comes the attraction of self-gravitation mouth 15 to stop.
In the present embodiment, the diameter of piston body 41 forms fully littlely than the internal diameter on straight tube road 34, for example in below 1/3 of internal diameter on straight tube road 34, therefore, when plunger 25 either direction the opposing party from connected state and dissengaged positions was switched, piston body 41 can not occur with the inwall on straight tube road 34 mobile slidably.Thus, can suppress the generation of plunger 25 and the resistance to sliding of the pipeline inner wall of working cylinder 24.Consequently, when removing pressing operation, only by the active force of lid 26, can prevent that plunger 25 from not returning the bad generation of the such action of primary importance.
By reducing the diameter of piston body 41, thereby make the diameter of the path that 34 interior attraction things pass through on the straight tube road become large.Thereby, can prevent the larger attraction thing situation that 34 interior generations are stopped up on the straight tube road.Need to prove, even if piston body 41 is being formed in the situation in thin footpath, guide by the conical surface 35a of the second valve seat 35 and the conical surface 43a of second valve section 49, plunger 25 is recovered to primary importance from the second position, thus can be reliably and close sleekly second valve 61.And, when plunger 25 moves from the second position to primary importance, also can suppress loosening.
In aforesaid present embodiment, under the effect of cam surface 39 and cam-follower 46, plunger 25 is tilted, and in the second valve seat 35, make piston body 41 off-centre, therefore, the passage sections that correspondingly increases second valve 61 with this offset is long-pending, compared with prior art, can not can make large-sized semisolid thing or solids occur to attract with stopping up.
In the above-described embodiment, the elastic-restoring force in the skirt section 51 by lid 26, plunger 25 is maintained the dissengaged positions of primary importance, but, such as also passing through helical spring etc. is installed between the upper end of cap 50 and working cylinder 24, and by this helical spring active force, to plunger 25 towards the primary importance application of force.
In the above-described embodiment, metal mouth 27 consists of as the product that pay to belong to of working cylinder 24, but, is provided with in other such embodiments of the second valve seat 35 at working cylinder 24, also can split formation metal mouth.
