Description
Technical field
This utility model relates to the teaching aid special for measuring student's vital capacity, relates to a kind of simple and easy tub vital capacity tester specifically.
Background technology
Traditional tester being used for measuring student's vital capacity is with a floating drum, a flexible pipe and a large basin water, using method is that floating drum is filled water, and flexible pipe is injected floating drum, turns around to be put in large basin and blows, measure vital capacity, effort very time-consuming when measurement, very inconvenient.
Summary of the invention
The technical problems to be solved in the utility model is for above deficiency, provides a kind of simple and easy tub vital capacity tester, and this simple and easy tub vital capacity tester continuously can measure vital capacity.
In order to solve above technical problem, this utility model by the following technical solutions:
A kind of simple and easy tub vital capacity tester, is characterized in that: comprise chamber, is provided with the floating drum that can move up and down along chamber in described chamber;
The bottom of described chamber is fixed with escape pipe, described escape pipe is communicated with two symmetrically arranged air blowing inlet pipes,
Described air blowing inlet pipe is communicated with flexible pipe, is provided with check valve between flexible pipe and air blowing inlet pipe.
Below the further improvement to technique scheme:
Described escape pipe is communicated with the exhaustor vertical with escape pipe.
Described exhaustor is fixedly installed drain tap.
The outer wall of described floating drum is provided with scale.
Described housing has the transparent material window that transparent material is made.
Arrange two inflatable mouths with check valve, an inflatable mouth is when test, and another can change blow gun, improves the efficiency of test, saves the time of test; This teaching aid structure is simple, easy to use, with low cost, is convenient to promote.
Below in conjunction with drawings and Examples, the utility model is described in further detail.

Detailed description of the invention
Embodiment, as shown in Figures 1 and 2, a kind of simple and easy tub vital capacity tester, comprises housing 1, has chamber 2 in described housing 1, be provided with the floating drum 3 that can move up and down along housing 1 in described chamber 2; The bottom of described chamber 2 is fixed with escape pipe 4, and described escape pipe 4 is communicated with two symmetrically arranged air blowing inlet pipes 61, described air blowing inlet pipe 61 is communicated with flexible pipe 7, is provided with check valve 6 between flexible pipe 7 and air blowing inlet pipe 61; Described flexible pipe 7 is provided with blow gun 8.
Described floating drum 3 can slide up and down along escape pipe 4, the bottom opening of floating drum 3.
Described escape pipe 4 is communicated with the exhaustor 5 vertical with escape pipe 4; Described exhaustor 5 is fixedly installed drain tap 51; The outer wall of described floating drum 3 is provided with scale 31; Described housing 1 has the transparent material window 9 that transparent material is made.
Blow from a blow gun during use, because there are check valve and drain tap in another two ends, air-flow can only be given vent to anger from outlet side in floating drum, and along with air blowing, floating drum rises, and blows and stops, writing down the scale of floating drum.Open venting valve, in floating drum, air is discharged from valve, and when blowing from flexible pipe, another flexible pipe can change blow gun, when cavity bottom fallen by floating drum, shuts valve of giving vent to anger, and another flexible pipe is blown, and so continuously measures vital capacity; This utility model structure is simple, easy to use, and at a blow gun when test, another can change blow gun, improves the efficiency of test, saves the time of test.
