In order to solve the above-mentioned technical problem, the utility model provides following technical solution：
A kind of chemical experiment flask with suction pipe of the utility model, including spheroidal body and bottleneck, the spheroidal body
Top be provided with bottleneck, flask transverse tube is provided with the outside of the bottleneck, the end set of the flask transverse tube has liquid suction
Go out device pipe, the bottleneck is internally provided with flask suction pipe, and the side of the liquid suction device pipe is provided with piston push
Bar, the side inside the liquid suction device pipe are provided with ring baffle, and the side of the ring baffle is connected with spring, institute
The one end for stating spring is connected with piston.
As a kind of optimal technical scheme of the utility model, the bottom of the flask suction pipe is in contact with spheroidal body.
As a kind of optimal technical scheme of the utility model, the flask transverse tube is connected with flask suction pipe, and liquid is inhaled
Go out device pipe with flask suction pipe to be connected.
As a kind of optimal technical scheme of the utility model, the top of the bottleneck is provided with flask bottleneck.
As a kind of optimal technical scheme of the utility model, the piston push rod runs through liquid suction device pipe and work
Plug is connected.
Compared with prior art, the beneficial effects of the utility model are as follows：
The utility model is a kind of chemical experiment flask with suction pipe, there is provided a kind of chemical experiment with suction pipe is burnt
Bottle, improves the security of chemical experiment, and the controllable volume for pouring out liquid in flask, have it is simple in structure, it is easy to operate,
To use raising convenience.

Embodiment
The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it will be appreciated that described herein excellent
Select embodiment to be only used for describing and explaining the present invention, be not used to limit the utility model.
Embodiment 1
As shown in Figs. 1-2, the utility model provides a kind of chemical experiment flask with suction pipe, including 1 He of spheroidal body
Bottleneck 2, the top of spheroidal body 1 are provided with bottleneck 2, and the outside of bottleneck 2 is provided with flask transverse tube 4, and the end of flask transverse tube 4 is set
Liquid suction device pipe 5 is equipped with, bottleneck 2 is internally provided with flask suction pipe 3, and the side of liquid suction device pipe 5 is provided with work
Push rod 9 is filled in, the side inside liquid suction device pipe 5 is provided with ring baffle 6, and the side of ring baffle 6 is connected with spring
7, one end of spring 7 is connected with piston 8.
Further, the bottom of flask suction pipe 3 is in contact with spheroidal body 1, when chemical liquid to be extracted out, flask suction pipe
3 can make thoroughly to drain during the chemical liquid of 1 bottom of spheroidal body only.
Flask transverse tube 4 is connected with flask suction pipe 3, and liquid suction device pipe 5 is connected with flask suction pipe 3, makes flask bottle
Liquid in body 1 can come out, easy to use.
The top of bottleneck 2 is provided with flask bottleneck 10, facilitates flask to pour into chemical liquid.
Piston push rod is connected through liquid suction device pipe with piston, can lead to convenient promotion piston 8, preferably extraction
Chemical liquid in flask.
Specifically, the utility model is when in use, when the liquid reactions in spheroidal body 1 are completed, it is necessary to pour out
