Abstract
The utility model discloses a fresh oxygen machine, of which the oxygen concentration is cut over straightly with a switch, the oxygen receiver of the fresh oxygen machine is connected with an oxygen outlet by two Y-joints which are divided into two gas paths in parallel, the first gas path is provided with an adjustable cut-out valve and a switch valve, the second gas path is provided with an adjustable cut-out valve. Users can cut over different concentration of the oxygen discharging straightly, which saves the users from a trouble of adjusting the flow-meter and is convenient in use.
Description
Technical field
The utility model relates to a kind of fresh oxygen machine that directly switches concentration with switch.
Background technology
In the market, the oxygen generation concentration of fresh oxygen machine adopts under meter to regulate, when the user uses, and frequent rotation flow meter back and forth, and to judge with the naked eye that whether the size of flow is fit to the oxygen generation concentration of own requirement, therefore, uses cumbersome.
Summary of the invention
The purpose of this utility model is: a kind of fresh oxygen machine that directly switches concentration with switch is provided, it is in parallel to be divided into the two-way gas circuit between the gas-holder of this fresh oxygen machine and the oxygen exhaust, and the oxygen generation concentration of two-way gas circuit height is different, the user can directly be switched the different oxygen generation concentration of height with switch-valve, saved the trouble of regulating under meter, it is extremely convenient to use.
The technical solution of the utility model is: a kind of fresh oxygen machine that directly switches concentration with switch, it is in parallel to be divided into the two-way gas circuit between the oxygen gas-holder of described fresh oxygen machine and the oxygen exhaust, adjustable shut off valve and switch-valve are installed on first gas circuit, adjustable shut off valve is installed on second gas circuit.
The further technical scheme of the utility model is: a kind of fresh oxygen machine that directly switches concentration with switch, it is in parallel to be divided into the two-way gas circuit between the oxygen gas-holder of described fresh oxygen machine and the oxygen exhaust, adjustable shut off valve and switch-valve are installed on first gas circuit, adjustable shut off valve is installed on second gas circuit; Between the oxygen gas-holder of described fresh oxygen machine and the oxygen exhaust with two Y-junctions and be unified into the tow channel gas road.
The utility model has the advantages that:
1. it is in parallel to be divided into the two-way gas circuit between gas-holder of the present utility model and the oxygen exhaust, and the oxygen generation concentration of two-way gas circuit height is different, the user can directly be switched the different oxygen generation concentration of height with switch-valve, has saved the trouble of regulating under meter, and it is extremely convenient to use.
2. owing on first gas circuit adjustable shut off valve and switch-valve are installed, adjustable shut off valve is installed on second gas circuit, and the flow difference of two adjustable shut off valves, so the user is as long as switch-valve of operation is the different concentration of giving vent to anger of changeable height.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a schematic appearance of the present utility model;
Fig. 2 is a structural representation of the present utility model.
Wherein: 1 oxygen gas-holder; 2 oxygen exhausts; 3 first gas circuits; 4 adjustable shut off valves; 5 switch-valves; 6 second gas circuits; 7 adjustable shut off valves; 8 Y-junctions.
Embodiment
Embodiment: as shown in Figure 1 and Figure 2, a kind of fresh oxygen machine that directly switches concentration with switch, it is in parallel to be divided into the two-way gas circuit with two Y-junctions 8 between the oxygen gas-holder 1 of described fresh oxygen machine and the oxygen exhaust 2, be equipped with on first gas circuit 3 on adjustable shut off valve 4 and switch-valve 5, the second gas circuits 6 adjustable shut off valve 7 is installed.
It is in parallel to be divided into the two-way gas circuit between gas-holder 1 of the present utility model and the oxygen exhaust 2, and the oxygen generation concentration of two-way gas circuit height is different, the user can directly be switched the different oxygen generation concentration of height with switch-valve 5, has saved the trouble of regulating under meter, and it is extremely convenient to use; Owing to are equipped with on adjustable shut off valve 4 and switch-valve 5, the second gas circuits 4 on first gas circuit 3 adjustable shut off valve 7 is installed, and two adjustable shut off valves 4 are different with 7 flow, so the user is as long as switch-valve 5 of operation is the different concentration of giving vent to anger of changeable height.
