Description
Technical field
The utility model relates to teaching experiment appliance technology more particularly to atmospheric pressure confirmatory experiment devices.
Background technique
Atmospheric pressure is the atmospheric pressure acted on unit area, that is, is equal on unit area and extends up on atmosphere
The weight of the vertical blank air column on boundary, earth surface exist.In teaching experiment, it is often necessary to verify the presence of atmospheric pressure, pass
The teaching experiment apparatus of system has the following deficiencies: that 1, phenomenon is not intuitive obvious enough；2, qualitative analysis, no quantitative analysis are only capable of.
Based on this, the applicant specializes in this, develops atmospheric pressure confirmatory experiment device, thus this case produces
It is raw.

In order to solve drawbacks described above existing in the prior art, the utility model provides atmospheric pressure confirmatory experiment device,
Have the characteristics that experimental phenomena is relatively intuitive, experimental result quantification is convenient for statistical analysis.
To achieve the goals above, the technical solution that the utility model is taken is as follows:
Atmospheric pressure confirmatory experiment device, including pedestal, the conical flask being mounted on the base, the pressure being connected to the conical flask
Strong sensor and air extractor are installed in conical flask and inverted test tube.
Preferably, the conical flask includes body, bottle stopper, blow vent on bottle stopper and on body
Bleeding point, the pressure transducer are connected with the blow vent, and the air extractor is connected with the bleeding point.
Preferably, the pedestal is equipped with mounting groove, the cone in order to keep conical flask more stable during the experiment
Shape bottle is installed in the mounting groove.
Preferably, the pedestal is equipped with bracket, the pressure transducer is installed on the bracket.
Preferably, further including the data collector being connected with the pressure transducer.Pressure transducer and data acquisition
Experimental result quantification may be implemented in the setting of device, convenient for statistical analysis, result is made to have data supporting, more convincing.
Preferably, the test tube is installed in the bottle stopper, the test tube interior fills liquid, and test tube mouth passes through thin modeling
Paper sealing.Bottle stopper is arranged to the structure of test tube bottom can be installed, experimental provision overall simple can be made, facilitate installation and behaviour
Make.
Preferably, the air extractor uses pump bowl.
Preferably, the pressure transducer is connect by mounting rack with bracket, the position between the mounting rack and bracket
It sets adjustable.
The utility model is able to achieve following technical effect:
(1) experimental phenomena is more intuitive: being evacuated with pump bowl, until inverted invisible spectro water falling off with thin modeling paper
And the phenomenon that pouring down, is obvious.
(2) experimental result accurate quantification, it is more convincing, convenient for analysis.
(3) experimental provision is simple, easy to operate.
Detailed description of the invention

1, water is in vitro filled, thin modeling paper is overlying on test tube mouth, test tube is gently inverted, is careful not to rock.Make thin modeling
Paper is encapsulated in inverted test tube mouth and water is not poured out.In careful immigration conical flask 3, rubber stopper is stoppered.
2, experimental provision is connected as shown in Figure 1；Pressure transducer 4 is accessed into predetermined position, passes through hose and bottle stopper 31
On blow vent 32 connect.
3, it is evacuated with pump bowl, until inverted invisible spectro water pours down with thin falling off for paper of modeling, data are adopted
Storage connects computer, produces chart on computers.
The above content is combination preferred embodiments of the present invention to further detailed made by provided technical solution
Describe in detail bright, and it cannot be said that the utility model specific implementation is confined to these above-mentioned explanations, technology affiliated for the utility model
