Description
Technical field
This utility model is related to a kind of direct-filling type flask, belongs to teaching equipment field.
Background technology
Flask is that have neck glass drying oven used in laboratory, for holding liquid material.Because can with resistance to certain heat quilt
It is referred to as flask.Flask generally have flat and round bottom point.Flat be called boiling flask, round bottom be round-bottomed flask.Flask leads to
Often there is the outward appearance of the thin neck of round tripe, significantly different from beaker.Its slot is used to prevent solution from spilling or reduces solution
Evaporation, and the use of rubber closure can be coordinated, to connect other glass equipment.When solution needs to react for a long time or add
During hot reflux, typically all can select flask to be used as container.The opening of the flask not prominent breach as beaker, topples over molten
It is more easy to during liquid flow down along outer wall, so generally all bottleneck can be touched to prevent solution from flowing down along outer wall with glass rod.Flask is because of bottleneck
Very narrow, inapplicable glass rod stirring, when if desired stirring, can hold the micro- wrist of changing hands of bottleneck can smoothly stir.If heating
During backflow, then can put into magnetic stick in what bottle, be stirred with heating stirrer.But existing flask shape system is single, no
Diversified requirement of imparting knowledge to students now can be met.
Utility model content
In view of the shortcomings of the prior art, technical problem to be solved in the utility model is to provide a kind of direct-filling type
Flask, easy to use.
For solving above-mentioned technical problem, this utility model adopts the technical scheme that, a kind of direct-filling type flask, including flask
Body, flask body is spherical, and the bottom of flask body is provided with horizontal ends, and the top of flask body is provided with one and drips
Geat, instillation mouth is cylindrical；The sidepiece of described instillation mouth is provided with an auxiliary port, and auxiliary port is cylindrical,
It is provided with a push-and-pull pipe, push-and-pull pipe and auxiliary port are slidably connected in auxiliary port；Some instillation is provided with described auxiliary port carve
Degree；One taper dropper is provided with described instillation mouth, taper dropper is provided with some scale grooves；The axis of described auxiliary port
Axis with instillation mouth is in 43.5 degree of angles；Two dropper retainer ring be arrangeding in parallel are provided with the inwall of described instillation mouth；
Described instillation mouth lower end is provided with the auxiliary filler pipe of a taper, and the lower end of auxiliary filler pipe is apart from flask body interior bottom surface
Distance be flask body height 1/3.2；The taper axis of described auxiliary filler pipe is 63.5 degree with the angle of horizontal ends.
Optimize, above-mentioned direct-filling type flask, the thickness of described drag is 2.45 times of flask sidewall thickness.
The utility model has the advantage of the drawbacks of it can overcome prior art, reasonable in design novelty.Chemistry is one
Plant accurate science, particularly in compound heating mixing, adding of component differs the result that a milli all can affect to test.?
In teaching during chemical experiment demonstration, it is difficult to quantify because the dosage of component adds, even if adding due to hand extruding using dropper
Inequality, also can occur the amount instiling to be more than or less than the required amount of experiment.Instillation mouth is increased in the technical scheme of the application
With push-and-pull pipe, by the piston movement of push-and-pull pipe, component in taper dropper component as required is added, convenient control,
Reduce the probability that component component adds mistake.The technical scheme inconvenience of the application is stirred during the course of the reaction, so
Increase an auxiliary filler pipe so that the component of filling is directly filled into the bottom of liquid in bottle, facilitate component and liquid in bottle
It is fully contacted reaction, improve reaction rate.
Brief description
Fig. 1 is structural representation of the present utility model；
In figure：1 is flask body, 2 is horizontal ends, 3 is instillation mouth, 4 is auxiliary port, 5 is push-and-pull pipe, 6 is instillation scale,
7 is taper dropper, 8 is dropper retainer ring, 9 is auxiliary filler pipe.
Specific embodiment
The technical characterstic of the present invention is expanded on further below in conjunction with the accompanying drawings with specific embodiment.
This utility model is a kind of direct-filling type flask, and including flask body, flask body is spherical, the bottom of flask body
It is provided with horizontal ends, the top of flask body is provided with an instillation mouth, instillation mouth is cylindrical；Described instillation mouth
Sidepiece be provided with an auxiliary port, auxiliary port is cylindrical, is provided with a push-and-pull pipe in auxiliary port, push-and-pull pipe with auxiliary
Mouth is helped to be slidably connected；Some instillation scales are provided with described auxiliary port；One taper dropper is provided with described instillation mouth, cone
Some scale grooves are provided with shape dropper；The axis of described auxiliary port is in 43.5 degree of angles with the axis of instillation mouth；Described instillation
It is provided with two dropper retainer ring be arrangeding in parallel on the inwall of mouth；The auxiliary that described instillation mouth lower end is provided with a taper adds
Note pipe, the distance apart from flask body interior bottom surface for the lower end of auxiliary filler pipe is the 1/3.2 of flask body height；Described auxiliary
The taper axis of filler pipe and the angle of horizontal ends are 63.5 degree.The thickness of described drag is the 2.45 of flask sidewall thickness
Times.
The utility model has the advantage of the drawbacks of it can overcome prior art, reasonable in design novelty.Chemistry is one
Plant accurate science, particularly in compound heating mixing, adding of component differs the result that a milli all can affect to test.?
In teaching during chemical experiment demonstration, it is difficult to quantify because the dosage of component adds, even if adding due to hand extruding using dropper
Inequality, also can occur the amount instiling to be more than or less than the required amount of experiment.Instillation mouth is increased in the technical scheme of the application
With push-and-pull pipe, by the piston movement of push-and-pull pipe, component in taper dropper component as required is added, convenient control,
Reduce the probability that component component adds mistake.The technical scheme inconvenience of the application is stirred during the course of the reaction, so
Increase an auxiliary filler pipe so that the component of filling is directly filled into the bottom of liquid in bottle, facilitate component and liquid in bottle
It is fully contacted reaction, improve reaction rate.
Certainly, described above is not to restriction of the present utility model, and this utility model is also not limited to the example above, this
The those of ordinary skill of technical field, in essential scope of the present utility model, change, remodeling, interpolation or the replacement made, all
Protection domain of the present utility model should be belonged to.
