Abstract
The utility model relates to a scuba, particularly a utility model of a scuba with an automatic air supply device, wherein, the scuba with an automatic air supply device realizes that air can only flow in a single direction in the air inlet valve and the air outlet valve of the device through the automatic opening and closing of the air inlet valve and the air outlet valve. Consequently, divers is ensured to be able to inhale fresh air through the water surface facilities, such as floating bodies, boats on the water surface, etc. The utility model which has the advantages of simple structure, low cost and convenient operation is applicable for underwater observation, fishing, tour and working in anoxybiotic and noxious-gas places.
Description
The utility model is about submersible, particularly supplies the utility model of air latent hydrophone automatically.
Observe in order to finish in shallow water, underwater operation such as collection, now still need the gas feeder of diving under water, in the present applied diving equipment, the general employing carries oxygen bottle, air bottle or carry the submersible that can produce chemical substance because the submersible of usefulness need be changed oxygen, pressurized air or chemical substance now, uses extremely inconvenient, and price is higher, is not easy to apply.
The purpose of this utility model just provides a kind of submersible, and this submersible does not need to increase accessory equipment again in using, and directly obtains air from the water surface, carries out the shallow water under-water operation under the situation of benign climate at any time.
The purpose of this utility model is to realize like this, this submersible is by the automatic shutter of air inlet valve and air outlet valve, realize that gas can only flow along a direction in the air inlet pipe of this device and freeing pipe, thereby guarantee that the ducker can breathe ozone by the admission port and the air extractor duct of the buoyancy aid on the water surface.
The utility model is because be directly to obtain air from the water surface, changes the inconvenience that oxygen, pressurized air or chemical substance are brought so compare to have saved with submersible in the past.Because this apparatus structure is simple, does not need to increase accessory equipment in the use, therefore, price is low, and is easy to use.
The concrete structure of utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is the structural representation of an embodiment of this utility model.
Fig. 2 is the structural representation of this embodiment air inlet valve and air outlet valve.
Fig. 1: this device comprises buoyancy aid (1), an admission port (2) and an air extractor duct (3) are arranged on buoyancy aid (1), buoyancy aid (1) can be made various ways, and its effect is to float on the surface, and guarantees that admission port (2) and air extractor duct (3) surface.One end of air inlet pipe (4) and freeing pipe (5) links to each other with air extractor duct (3) with admission port (2) respectively by buoyancy aid (1), and the other end of air inlet pipe (4) and freeing pipe (5) links to each other with the upper vent hole (14) of air inlet air storage chamber (6) and the upper vent hole (15) of the air storage chamber of giving vent to anger (7) respectively.Air inlet air storage chamber (6) is identical with its structure of the air storage chamber of giving vent to anger (7), is respectively to have an air extractor vent can store the container of air up and down, and its effect is the pressure when alleviating people's inspiration and breath.One end of inlet channel (8) and gas off-take (9) links to each other with the following air extractor vent (16) of air inlet air storage chamber (6) and the following air extractor vent (17) of the air storage chamber of giving vent to anger (7) respectively, the other end of inlet channel (8) and gas off-take (9) links to each other with the cover (18) of exhaling, the effect of covering (18) of exhaling is that people's respiratory apparatus and surrounding environment are isolated, and the people can only be from exhalation vents (12) by air inlet valve (10) and air outlet valve (11) breathe air.The space of exhalation vents (12) should not done too greatly, to guarantee gas flowing well in device.(13) in the diagram are luntttes.
Fig. 2: this valve comprises valve body (19), moving vane (20) and axle (21), and moving vane (20) can rotate around axle (21).
When this valve is installed as air inlet valve, can be from exhalation vents (12) direction along arrow (22) be fixed on shown in (10) on the position.When installing, can be fixed on from exhalation vents (12) along arrow (22) opposite sense shown in (11) on the position as air outlet valve.The geomery of valve installation place should be consistent with the geomery of valve body, and after guaranteeing that valve is installed, the valve body outside seal is good, and gas can only pass in and out from valve.
Principle of work of the present utility model is as described below, the gas that the exhalation vents (12) that the people covers by exhaling is breathed out is by the unlatching of the valve of giving vent to anger (11) and closing of air intake valve (10), make air communication cross gas off-take (9) and enter the air storage chamber of giving vent to anger (7), by freeing pipe (5), the gas of breathing out is delivered to the air extractor duct (3) of buoyancy aid (1) and put into atmosphere then.The gas of exhalation vents (12) inspiration that the people covers by exhaling is by the unlatching of air intake valve (10) and closing of the valve of giving vent to anger (11), gas enters air inlet air storage chamber (6) from admission port (2) by air inlet pipe (4), and gas is delivered to the exhalation vents (12) of the cover of exhaling by inlet channel (8) and air intake valve (10) by air inlet air storage chamber (6).
Claims (1)
1, submersible, particularly confess the air latent hydrophone, a buoyancy aid (1) and the cover (18) of exhaling are housed on it, it is characterized in that: an admission port (2) and an air extractor duct (3) are arranged on buoyancy aid (1), near the exhalation vents (12) of the cover (18) of exhaling, an air inlet valve (10) and an air outlet valve (11) are housed.
