Description of the drawings
Fig. 1 is the first state schematic diagram of the present invention.
Fig. 2 is second view of the present invention.
Specific embodiment
Shown in Fig. 1, Fig. 2, it is related to a kind of electric liquid suction device suck-back alarm device, including cavity structure 2, the cavity structure
2 top is provided with the output pipe portion structure 1 extended in the cavity structure 2, and the bottom of the cavity structure 2 is provided with prolongs
Reach the input pipe portion structure 3 in the cavity structure 2；Wherein, the input pipe portion structure 3 is located in the cavity structure 2
Part and the cavity structure 2 between be formed with a reservoir 4；The upper surface of the cavity structure 2 offers a circular hole 7,
One is inserted with the circular hole 7 may extend to the induction alarm device in the reservoir 4；Wherein, the induction alarm device
Including liquid level inducing probes 5, a honeycomb pipes device, and one is that the liquid level inducing probes 5 and honeycomb pipe
Device provides the button cell of working power.
Further scheme is that the upper end of the liquid level inducing probes 5 is provided with cavity round platform 6, in the cavity round platform 6
It is provided with the button cell and honeycomb pipes device.
Further scheme is that the input pipe portion structure 3, cavity structure 2 and output pipe portion structure 1 are tied for integral type
Structure.
Further scheme is to be provided with the circular hole 7 and can puncture silica gel cushion.
Further scheme is that the cavity structure 2 is cylinder, and its a diameter of 1.3cm-1.5cm is highly 2.5cm-
3cm.
Further scheme is, the input pipe portion structure 1 is cylinder, and its external diameter is 0.6-0.7cm, and internal diameter is
0.45-0.55cm.
Further scheme is, the output pipe portion structure 3 is cylinder, and its external diameter is 0.75-0.85cm, and internal diameter is
0.6-0.7cm.
Further scheme is that the input pipe portion structure 3 extends 1cm-1.5cm into the cavity structure 2.
Further scheme is that 3 lower end of input pipe portion structure is embedded with rubber washer 8 around peristome, for ensureing
The sealing of suction pipe and device connecting portion during imbibition.
During use, input pipe portion structure 1 is inserted into electrical pipette rifle rifle mouth, is put in standby on one side；When needing liquid relief, will
Pipet insertion output pipe portion structure 3, pins the switch imbibition of electrical pipette rifle.
When such as operator's imbibition is excessive, in the reservoir 4 that liquid can be entered in cavity structure 2, liquid level inducing probes 5 are felt
To after liquid should trigger honeycomb and pipe device 6, produce warning, remind operator's imbibition excess.Now operator stop at once
Only imbibition, pipet is extracted, and electric liquid suction device suck-back alarm device is removed from electrical pipette rifle, extracts liquid level sensing
Probe 5, the single use structure of pollution is abandoned.Need during imbibition again, to retrieve a new single use knot
Structure, the liquid level inducing probes 5 after insertion sterilizing (as clean with 75% alcohol wipe), is continuing with.
Wherein, the reservoir 4 in cavity structure 2, because space is less, as long as the about a small amount of liquid of suction, can just reach energy
The level that triggering liquid level inducing probes are reported to the police, can remind experiment operator, in time while also can be stored in waste liquid
In cavity structure, prevent waste liquid to be back in sample by pipet, pollute or experimental error.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and
