Description

A kind of from the air feed diving apparatus

Technical field

The utility model relates to diving with breathing floating gas feeder, relates in particular to breathe and floating utensil for the automatic air feed of optional position scuba diver in relative water depth.

Background technology

The device or the utensil of the existing confession person of playing in the water underwater breathing are in the majority with " wear-type ", because of the structure especially limitation of breather pipe length, the user can not dive to playing than under the deep water with it, even can not be with they enjoyments freely that (contain the abyssal zone) at the bottom of standard swimming pool enjoyment of diving under water; Air-supply mask in the specialty diving equipment must rely on the oxygen bottle oxygen supply, said oxygen bottle or reduce the property freely of diving under water, or must be by be communicated to the ventilation channel oxygen supply of oxygen bottle on the water always because of bearing voluntarily by the scuba diver, pind down and freedom poorer.

Summary of the invention

The purpose of this utility model is that realization is a kind of from the air feed diving apparatus, and it can be breathing and the floating automatic air feed of optional position scuba diver in relative water depth.

The utility model is said from the air feed diving apparatus, and air inlet pipe and exhaust tube are arranged, and respiratory system, inflation floating system and air inlet threeway are characterised in that:

A) air extractor duct of the admission port of air inlet pipe and exhaust tube is communicated with atmosphere on the water surface respectively, and the inlet end of respiratory system and inflation floating system is all excessively managed by air inlet threeway and air inlet and is communicated with air inlet pipe;

B) respiratory system has the breathing threeway, its three mouths are respectively air suctiton inlet, exhalation vents and pneumostome, air suctiton inlet is communicated with air inlet threeway and air inlet pipe by air-breathing excessive pipe, between air suctiton inlet and the air inlet threeway breather cheek valve is arranged, pipe is communicated with exhaust tube exhalation vents by exhaling excessively, between the air extractor duct of exhalation vents and exhaust tube expiratory one-way valve is arranged, pneumostome is communicated with the breathing head;

C) the inflation floating system has each two of the appendix of inflatable pneumatic bag and airbags in the middle of comprising, appendix one end is communicated with air inlet threeway and air inlet pipe by inflation threeway, hyperinflation pipe, the other end is communicated with airbag, the airbag check valve is arranged in the loading line between inflatable pneumatic bag and the airbag, in the loading line between inflatable pneumatic bag and the inflation threeway air bag check valve is arranged.

The inlet end of the utility model respiratory system and inflation floating system by air inlet threeway, air inlet excessively pipe and air inlet pipe be communicated with atmosphere, so atmosphere promptly is the source of the gas of these two systems, realized " from air feed ".

For making the said respiratory system function of bringing into normal play, all freely smooth and easy when " air-breathing " and " expiration " when guarantee using amateurish scuba diver of the present utility model to breathe under water, when " air-breathing " not by before this or the waste gas of after this breathing out disturb, the utility model respiratory system is between the air suctiton inlet and air inlet threeway of breathing threeway, between the air extractor duct of exhalation vents and exhaust tube, by the respiratory air flow flow direction breather cheek valve and expiratory one-way valve are housed respectively, when then the utility model user exhales by breathing head with mouth under water, expiratory one-way valve is opened and breather cheek valve is closed, and the waste gas of exhalation is in the exhalation path of breathing formation such as threeway and exhaust tube is arranged into atmosphere; Otherwise user's mouth is by breathing when air-breathing, and breather cheek valve is opened and expiratory one-way valve is closed, and the scuba diver is the air that the air suction way suction is derived from atmosphere that advances by the formation such as air inlet pipe of breathing threeway, air inlet threeway and being communicated with atmosphere under water.

Inflation floating system of the present utility model, be to carry out the scuba diver with it and in water, obtain buoyancy aid design-calculated beyond the water buoyancy for allowing, buoyancy aid is produced by the air that charges in the inflation floating system airbag, is fixed in that air charges into by inflatable pneumatic bag in the airbag of scuba diver's health.Based on considering to gas filed feasibility of airbag and efficiency with the inflatable pneumatic bag in the middle of the appendix, inflatable pneumatic bag and airbag and and the inflation threeway between loading line in, conceiving respectively has airbag check valve and air bag check valve; Is like this with inflatable pneumatic bag to the gas filed process of airbag, normality lower gasbag check valve is opened and the airbag closed check valve, and loading line is communicated with atmosphere inflatable pneumatic bag and filled naturally by atmosphere through advancing of forming of loading line, inflation threeway, hyperinflation pipe, air inlet threeway and the air inlet pipe of inflation between the threeway; When the scuba diver pinches the pressure inflatable pneumatic bag, airbag check valve between inflatable pneumatic bag and the airbag is opened and the air bag closed check valve, former air in inflatable pneumatic bag is pressed into airbag by loading line between inflatable pneumatic bag and the airbag, it can be full of by atmosphere again to decontrol inflatable pneumatic bag, after this pinch again press inflatable pneumatic bag then wherein air be pressed into airbag by meeting again, so air is also many more in the many more airbags of multiplicity, be that airbag buoyancy is big more, then the buoyancy aid that obtains in water of scuba diver is also big more, thus because of health bearing down in water alleviate in addition the prerequisite of disappear (if amount of air is enough suitable in the airbag) under the enjoyment of impression diving.
