Abstract
The utility model discloses a lung capacity measurer which comprises a base, a buoy, a vent pipe, an air duct and a detachable blowing nozzle. A partition plate is arranged in the base and divides the base into a water storage tank and a bottom tank, the buoy is placed in the water storage tank, an opening is formed in the lower end of the buoy, the upper end of the buoy is of a sealed structure, a hole is formed in the middle of the partition plate, the vent pipe is placed in the bottom tank, the upper end of the vent pipe extends into the buoy through the hole in the partition plate and the opening of the buoy and is higher than a water surface, the lower end of the vent pipe is bent rightwards, a vent hole is formed in the outer side of the bottom tank, one end of the air duct is connected with the vent pipe through the vent hole, and the other end of the air duct is connected with the detachable blowing nozzle. The lung capacity measurer is simple in structure, can be reused only by primary water filling and is conveniently and rapidly reused by opening a vent valve on the upper portion of the buoy, experimental data accuracy is ensured, and the detachable blowing nozzle can be replaced and is clean and sanitary.
Description
Technical field
This utility model relates to a kind of teaching and experiment equipment, specifically a kind of vital capacity detector.
Background technology
In education experiment, traditional vital capacity measuring instrument facility is fairly simple, directly floating drum is pressed down gas is discharged carrying out secondary laboratory, this kind of instrument is after air blowing, institute's blowing easily refluxes through airway, cause testing inaccurate, the easy antibacterial of many experiments blow gun contact human body infects, unhygienic.
Summary of the invention
The purpose of this utility model is to provide a kind of vital capacity detector.
This utility model will solve existing vital capacity detector and use inconvenience, and the experimental data error of generation is large, and antihygienic problem.
The technical solution of the utility model is: a kind of vital capacity measuring instrument, comprise base, floating drum, breather, airway and detachable blow gun, in described base, there is individual dividing plate, base is divided into water storing bin and hold, described floating drum is placed in water storing bin, floating drum lower end is provided with opening, upper end is enclosed construction, in the middle of described dividing plate, there is a hole, described breather is placed in hold, upper end is reached and in floating drum, is exceeded the water surface by the opening of the hole on described dividing plate and floating drum, lower end bends to the right, described hold outside is provided with a passage, described airway one end joins by passage and breather, the other end joins with detachable blow gun.
The beneficial effects of the utility model are: simple in structure, only need first dress water to get final product Reusability, during Reusability, only need open the breather valve venting of floating drum top, convenient and swift, detachable blow gun is replaceable, clean hygiene, one-way vent valve can guarantee that institute's blowing does not reflux, and guarantees that experimental data is accurate.
