Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the sectional view that the utility model embodiment removes when pressing control button;
Sectional view when Fig. 3 is the utility model embodiment pressing control button.
Detailed description of the invention
See Fig. 1 ~ Fig. 3, the suction device of a kind of endoscope of the present utility model, comprise control button 6, valve seat 2 and suction tube 1, the upper end of valve seat 2 is provided with valve gap 4, on valve gap 4, movable sleeve is provided with a universal driving shaft 5, the lower end of universal driving shaft 5 is provided with piston 7, the upper end of universal driving shaft 5 is connected with control button 6, control button 6 is push button, comprise button keycap 61 and back-moving spring 62, back-moving spring 62 one end is set in the lower end of button keycap 61, and other end top is pressed in the upper surface of valve gap 4, and the top of cavity 3 is connected with suction tube 1.
Also be provided with in valve seat 2 and supply fluid from one end to the cavity 3 that the other end circulates, the middle part of cavity 3 is provided with boss 31 and accommodation section 32, piston 7 can move back and forth between boss 31 and accommodation section 32, when piston 7 moves to boss 31 position, cavity 3 is cut off, and when piston 7 moves to 32 position, accommodation section, cavity 3 communicates.
In addition, valve gap 4 is also provided with and is communicated with hole 8 that is extraneous and cavity 3, the lower end of button keycap 61 is provided with the sealing block 9 that can block described hole 8, during to control button 6 pressing operation, and can the top of seal chamber 3 completely after sealing block 9 and valve gap 4 coordinate.
This suction device is arranged on the operating portion of endoscope, the external not shown negative pressure source of suction tube 1 other end, wherein, negative pressure source comprises Negative pressure machine, suction pump etc., the bottom of cavity 3 is connected with the suction pipeline in not shown insertion section, the cross section of cavity 3 each several part is circle, the surface of boss 31 is smooth curved surface, improve sealing and attraction is more outstanding, accommodation section 32 is funnel-shaped chamber, for providing guiding diffusion function when fluid flows to boss 31 from bottom to top, accelerating the flow velocity of fluid, also making attraction more outstanding simultaneously.
As shown in Figure 2, negative pressure source is in running order, attraction is produced to the fluid in suction tube 1, after the pressing removing control button 6, button keycap 61, universal driving shaft 5 and piston affect by the elastic force of back-moving spring 62, piston 7 moves to boss 31 position, cavity 3 is cut off, the circulation of fluid between suction pipeline and negative pressure source pipeline is blocked, simultaneously, hole 8 and sealing block 9 separately, negative pressure source pipeline by some through holes 10 to external world air attract, thus unnecessary overbottom pressure can not be produced to suction pipeline.
