Abstract
The utility model provides a gas collecting device, comprising a gas collecting chamber, a liquid containing cylinder, a switch and a conduit. The gas collecting device is characterized in that a liquid injection opening is arranged at the top of the liquid containing cylinder, and the lower part of the liquid containing cylinder is open; the gas collecting chamber is fixedly arranged around the lower half part of the liquid containing cylinder, and is communicated with a narrow seam at the bottom of the gas collecting chamber through the lower edge of the liquid containing cylinder; the gas collecting chamber is sealed; the conduit is fixedly arranged at the top of the gas collecting chamber; and the switch is fixedly arranged on the conduit. When the gas collecting device is in use, the switch is switched on, so that water is injected from the liquid inlet; the switch is switched off when the water flows out from the conduit; the conduit is connected with a gas making device by using a rubber pipe; the switch is turned on, the gas in the gas making device presses the water in the gas collecting chamber into the liquid containing cylinder; and when the collected gas meets requirements, the switch is turned off, so that a certain amount of the gas can be stored by using the gas collecting device for the next experiment. The gas collecting device has the advantages of simple structure, low gravity, difficulty in falling, convenience in use and small occupied area.
Description
Technical field
The utility model relates to the chemical experiment apparatus, is specifically related to a kind of convenient and practical gas collecting apparatus.
Background technology
In chemical experiment, often use gas bottle, laboratory gas bottle commonly used will be assembled by some supplementary instruments such as conduits with two isolated containers usually temporarily, not only time-consuming, and the place that takies is larger, high, the easily lodging of center of gravity, very inconvenient when doing experiment with gas bottle to other device air feed.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of convenient gas collecting apparatus that uses, is difficult for lodging is provided.
The utility model is realized by following technological means: a kind of gas collecting apparatus, comprise collection chamber, knapsack, switch, conduit, it is characterized in that: described knapsack bottom is uncovered, the top is provided with liquid injection port, collection chamber is fixedly installed on around the Lower Half of knapsack, and is connected by the narrow slit of knapsack lower edge with the collection chamber bottom.
Described collection chamber seals, and conduit is fixedly installed on the collection chamber top, and switch is fixedly installed on the conduit.
During concrete the use, open switch, from the inlet injected water, then closing switch when treating that water flows out from conduit is connected conduit with rubber tube with gas making device, open switch, gas in the gas making device with the hydraulic pressure in the collection chamber in knapsack, when the gas of collecting meets the demands, closing switch, namely available this gas collecting apparatus is preserved a certain amount of gas for experiment next time.
This gas collecting apparatus is simple in structure, center of gravity is low, is difficult for lodging, and easy to use, area occupied is little.
The utility model is simple in structure in addition, manufacturing cost and use cost are all lower, easy to manufacture, very easily promotes.
Although the above is described preferred embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, can also make the concrete conversion of a lot of forms, these all belong within the protection domain of the present utility model.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model
Among the figure: 1-collection chamber, 2-knapsack, 3-liquid injection port, 4-switch, 5-conduit, 6-liquid level.
The specific embodiment
Below in conjunction with description of drawings and the specific embodiment the utility model is described in further detail:
As shown in FIG., a kind of gas collecting apparatus, comprise collection chamber 1, knapsack 2, switch 4, conduit 5, it is characterized in that: described knapsack 2 bottoms are uncovered, the top is provided with liquid injection port 3, collection chamber 1 is fixedly installed on around the Lower Half of knapsack 2, and is connected by the narrow slit of knapsack 2 lower edges with collection chamber 1 bottom.
Described collection chamber 1 seals, and conduit 5 is fixedly installed on collection chamber 1 top, and switch 4 is fixedly installed on the conduit 5.
During concrete the use, open switch 4, from inlet 3 injected waters, then closing switch 4 when treating that water flows out from conduit 5 is connected conduit 5 with rubber tube with gas making device, open switch 4, gas in the gas making device with the hydraulic pressure in the collection chamber 1 in knapsack 2, when the gas of collecting meets the demands, closing switch 4, namely available this gas collecting apparatus is preserved a certain amount of gas for experiment next time.
