As shown in Fig. 1, the nipple 2 of suction pipe 1 and the top of interior tube body 3 are connected through a screw thread, suction pipe 1 and interior tube body
3 lumen therethrough.
As shown in Fig. 1, interior tube body 3 is located within outer tube body 4, and the end of outer tube body 4 is stretched out on the top of interior tube body 3, interior
The bottom end closure of tube body 3, outer tube body 4 and interior tube body 3 are made of hard material.The internal diameter of the outer diameter and outer tube body 4 of interior tube body 3
Unanimously, the tube wall of the two fits closely but interior tube body 3 can slide up and down inside outer tube body 4.
As shown in Fig. 1, it is respectively equipped with positive pressure connector 5 and negative pressure connector 6 on the tube wall close to 4 top of outer tube body, just
The lumen therethrough of crimp head 5, negative pressure connector 6 and outer tube body, positive pressure connector 5 and negative pressure connector 6 are vertically set up and down on outer tube body
It sets.
As shown in Fig. 1, the tube wall of interior tube body 3 is equipped with open slot 7.
In use, positive pressure connector 5 is connect with positive airway pressure apparatus, negative pressure connector 6 is connect with negative pressure equipment, as shown in Fig. 1,
After negative pressure connector 6 and open slot 7 penetrate through, negative pressure connector 6 is penetrated through by interior tube body 3 and suction pipe 1, and positive pressure connector 5 is by inner tube
The tube wall of body 3 blocks, and negative pressure equipment is open-minded at this time, and negative pressure is generated inside interior tube body 3 and suction pipe 1, carries out normal suction work
Make.After being stopped up such as suction nozzle 1, interior tube body 3 is move upwardly until that open slot 7 is penetrated through with positive pressure connector 5, positive pressure connector 5 is logical
Interior tube body 3 is crossed to penetrate through with suction pipe 1, and negative pressure connector 6 is blocked by the tube wall of interior tube body, supplies positive pressure, the blocking in suction nozzle 1 at this time
Object is rushed out, and realizes back flush work.
As shown in Fig. 1, for prevent impurity entered in negative pressure equipment by negative pressure connector 6 or by positive pressure connector 5 into
Enter into suction pipe, filter screen 8 is internally provided in negative pressure connector 6 and positive pressure connector 5.
For the leakproofness for ensureing between interior tube body 3 and outer tube body 4, as shown in Fig. 1, between outer tube body 4 and interior tube body 3
Equipped with sealing ring 9, sealing ring 9 is located in the ring dress groove of outer tube body inner wall, and sealing ring is two, setting up and down.It is close to two
The spacing of seal should restrict, and should ensure that positive pressure connector 5 on outer tube body and negative pressure connector 6 between two sealing rings, and
And when interior tube body 4 moves up and down, open slot 7 on interior tube body is also between two sealing rings always, and when open slot 7 with
After positive pressure connector 5 penetrates through, the bottom end of interior tube body is located at below lower layer's sealing ring.
A kind of device for driving interior tube body 3 to move up and down is additionally provided in the present embodiment.
As shown in Fig. 1, the driving device include the leading screw 10 being connect with interior tube body bottom end, be located at outer tube body it is intraluminal
Feed screw nut 11, feed screw nut 11 and the inner wall of outer tube body are fixed, and 10 bottom end of leading screw passes through feed screw nut 11 and stretches out outer tube body
Bottom end.After the rotational lead screw, leading screw will produce it is upper and lower walk about, by leading screw walk about drive interior tube body 3 move up and down, for side
Just rotational lead screw is equipped with rotating handles 12 in the bottom end of leading screw.
Although the rotation of above-mentioned leading screw can drive interior tube body 3 to move up and down, the interior tube body 3 while rotation of leading screw 10
Also it can rotate, the rotation of interior tube body 3 can cause suction pipe 1 to rotate, and when suction pipe 1 is also connect with other equipment, rotate meeting
It interferes, therefore as shown in Fig. 1, in the present embodiment, is connected by bearing 13 between the bottom end and leading screw 10 of interior tube body 3
It connects, the bottom end and the outer ring of bearing 13 of interior tube body 3 are fixed, and 10 top of leading screw and the inner ring of bearing 13 are fixed.Using above-mentioned setting
Afterwards, leading screw 10 rotates, but interior tube body 3 will not rotate, but can be generated with moving up and down for leading screw 10 and in outer tube body 4
Lower slider.
By above-mentioned introduction about the construction it is found that when carrying out the conversion of positive pressure connector 5 and negative pressure connector 6, need in control
Tube body 3 moves up and down distance to ensure that open slot 7 can be penetrated through accurately with positive pressure connector 5 or negative pressure connector 6.In this implementation
A kind of positioning device is provided in example.
As shown in Fig. 1, positioning device includes limiting plate 14, and limiting plate includes upper limit plate 14-1, lower limiting board 14-2,
Upper and lower limiting plate is setting up and down on the inner wall of outer tube body 4, and interference lever is radially provided on the leading screw body between two pieces of limiting plates
15, the spacing between upper and lower limiting plate is consistent with the spacing between positive pressure connector 5 and negative pressure connector 6.
As shown in Fig. 1, after leading screw, which moves downwardly to interference lever 15, to be contacted with lower limiting board 14-2 interference, 10 nothing of leading screw
Method rotates, and cannot continue traveling downwardly, and open slot 7 is penetrated through with negative pressure connector 6 at this time, and positive pressure connector 5 is sealed by the tube wall of interior tube body 3
It is stifled.Rotate backward leading screw 10, leading screw uplink, after interference lever 15 and the 14-1 interference of upper limit plate contact, open slot 7 with just crimp
First 5 perforation, leading screw 10 can not continue to rotate backward, and cannot continue uplink, and negative pressure connector 6 is blocked by the tube wall of interior tube body.
The driving device that certain the present embodiment is provided is intended only as a kind of preferred embodiment and implements, can be in practical operation
It is pulled using by the way of the connecting rod of interior tube body bottom end, but which be easy to cause pulling force relative to leading screw driving or pushes away
The problem of power shakiness, open slot are difficult to accurately penetrate through with positive pressure connector or negative pressure connector, even if provided with the present embodiment provides rear
Limiting device, but easily cause when pulling force or excessively steep thrust interference lever or limiting plate fracture, positioning caused to fail.
Therefore the embodiment is only the better embodiment of the present invention, therefore all structures according to described in present patent application range
It makes, the equivalent change or modification that feature and principle are done, is included within the scope of present patent application.
