There are 2 locating slots on bit slice 132, there are 3 locating slots on third locating plate 133.First locating plate 131,132 and of the second locating plate
The left alignment of third locating plate 133, the right end of the first locating plate 131 are shorter than the right end to the second locating plate 132, therebetween
At least have for second pipe 112 and the gap placed side by side of third pipeline 113；The right end of third locating plate 133 is shorter than to the
The right end of two locating plates 132 at least has therebetween the gap placed for third pipeline 113.
Switch in the present embodiment selects handle switch, and handle switch includes handle and compressing member, handle and suction irrigation
Device main body 1 is rotatablely connected, and is supported with compressing member.Compressing member is equipped with pressing groove, and passes through compressed spring and suction washer
1 elastic connection of main body.
The present embodiment is provided with the switch 121 and switch 122 of independent control, and first pipe 111 and second pipe 112 are simultaneously
Across the pressing groove 123 of switch 121 and the pressing groove 124 of switch 122, third pipeline 113 passes through the pressing groove 124 of switch 122.
During installation, first pipe 111 by the first locating plate 131, the second locating plate 132 and third locating plate 133 co-locate, i.e.,
It is subject to and illustrates direction, first pipe 111 passes through the left locating slot of the left locating slot of the first locating plate 131, the second locating plate 132
With the left locating slot of third locating plate；Second pipe 112 by second locating plate 132 middle locating slot and third locating plate 133
Right locating slot positioning；Third straight pipe 113 is positioned by the right locating slot of the second locating plate 132.
First pipe 111 penetrates through always, and switch 121 controls the logical of the second straight pipe 112 and closes, and switch 122 controls third
It straight pipe 113 logical and closes.Switch 121 is identical as the logical principle closed of control pipeline of switch 122, i.e., under the action of the spring, just
When beginning state, second pipe 112 is pressed on the rear end side wall of the first locating plate 131 by the pressing groove 123 of switch 121, and second
Pipeline 112 is in close state.Similar, third pipeline 113 is pressed on third locating plate 133 by the pressing groove 124 of switch 122
Rear end side wall on, third pipeline 113 is also at closed state.
When needing to connect suction runner, the handle of push switch 121 rotates it towards 1 direction of suction washer main body,
The compressing member movement of handle pull switch 121 simultaneously, releases the extruding to second pipe 112, second pipe 112 is in own resilient
Effect is lower to restore, and second pipe 112 is in the conductive state, then the clast of operative site or liquid can pass through extensional pipeline 2-
The sequence of confluence part 15- second pipe 112 is sucked out.After releasing the pressing to 121 handle of switch, spring pushes compressing member multiple
Position, compressing member squeeze second pipe 112, and second pipe 112 restores to closed state.
When needing to connect flushing flow passage, the handle of push switch 122 rotates it towards 1 direction of suction washer main body,
The compressing member movement of handle pull switch 122 simultaneously, releases the extruding to third pipeline 113, third pipeline 113 is in own resilient
Effect is lower to restore, and third pipeline 113 is in the conductive state, then external flushing liquid can pass through third pipeline 113- confluence part
The sequence of 15- extensional pipeline 2 is rinsed operative site.After releasing the pressing to 122 handle of switch, spring, which pushes, to be compressed
Part resets, and compressing member squeezes third pipeline 113, and third pipeline 113 restores to closed state.
Referring to Fig. 5, Fig. 5 is the stereoscopic schematic diagram of the utility model one embodiment.It is the utility model one as shown in the figure
A embodiment be completed after external structure, when portion of the handle of the present embodiment, meets human body hand shape, comfortable to stablize, and handle
Switch meets the key curve of ergonomics, and finger is more comfortable when can make to press, switch size difference and the different (face of color
Color is not shown), it is easier to distinguish the feature difference taken out and inhaled.
It is illustrating for progress to be implemented to the preferable of the utility model, but innovation and creation are not limited to the implementation above
Example, those skilled in the art can also make without departing from the spirit of the present invention various equivalent variations or
Replacement, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
