Abstract
The utility model discloses an underwater breathing device; a gas bag is arranged in a cylindrical outer shell; a plurality of small holes are arranged at the periphery of the outer shell; the outer shell and the gas bag are collectively called as a gas storage device; a joint between the outer shell and the gas bag is provided with a gas inlet and a gas outlet; and the gas outlet is connected with a hose, and the end of the hose is connected with a control switch. The control switch comprises a gas valve which is controlled by biting force. The underwater breathing device has a simple structure, is very convenient to produce and manufacture, has very light weight and very low cost, is very applicable to ordinary people groups in all classes and ages who like swimming and other water games, and plays a very great protective role to beginners in swimming or other water games.
Description
Technical field
The utility model belongs to a kind of breather apparatus, particularly a kind of underwater breathing apparatus.
Background technology
Underwater breathing apparatus is a kind ofly can supply with oxygen or air under water, to such an extent as to the underwater length of the halt of people prolong so that finish the work or the action of some necessity.Generally speaking, underwater breathing apparatus all is that oxygen or pressurized air (also having some to utilize the underwater breathing apparatus of chemical reaction system oxygen) are stored in the abundant steel cylinder with carrying on the body on one's body for people's underwater breathing.Show through market research, such underwater breathing apparatus is bulky, heavy, cost an arm and a leg, thereby carrying shortcomings such as inconvenience causes it can only be applicable to some relevant speciality personnel generally speaking, or the crowd of only a few special requirement, only be to like swimming or other the general population of some outdoor activities waterborne and be not suitable for.
Because above-mentioned existing underwater breathing apparatus can not be applicable to masses, and just social investigation at present, almost be that all age brackets all exist and are numerous swimming fans really, or other some are liked the general population of aquatic sports.But, cause the annual people who dies because of drowning also in fact for numerous owing to people's the time of holding one's breath is too short.
Summary of the invention
The purpose of this utility model provides a kind of underwater breathing apparatus; this device solves because of liking in conjunction with the basic condition of existing underwater breathing apparatus and swims or the drowned tragedy problem that some other aquatic sports causes, and gives the first person's of the relating to necessary security protection of swimming or other aquatic sports and color, enjoyment and the safety factor of increase amusement on water.
The technical solution of the utility model is achieved in that
The gas storage air bag is installed in the cylinder type shell, the shell surrounding is provided with a plurality of apertures, and shell and gas storage air bag are referred to as accumulator unit jointly, is provided with admission port and air extractor duct at shell and gas storage air bag junction, air extractor duct is connected by a flexible pipe, and the end place connects master cock.
The gas valve that described master cock is controlled by biting force constitutes.
Described shell is that rigid plastic constitutes.
The utility model adopt ductility preferably elastomeric material make cyst wall thicker (increasing air pressure) so that can lay in more air the gas storage air bag (can with air constantly charge into and expand thereupon become big).The gas storage air bag is installed in the cylinder made from rigid plastic (solid, not yielding) (being shell).Be provided with a plurality of apertures around the shell, with the usefulness of water supply and sewage.The maximum swelling of air bag can only be full of the enclosure space.Shell and air bag are referred to as accumulator unit jointly, and this accumulator unit is provided with admission port and air extractor duct, and air extractor duct is connected by a flexible pipe, and the end place connects master cock.Master cock is stung by tooth and is realized gas purging and close.Only need inflate to device by admission port during inflation with common small-sized inflator.Gas filed whether expiring, can judge whether gas is full of by the degrees of expansion that the aperture of shell is observed air bag.This accumulator unit is fixed in back by braces.
The utility model has the advantages that: simple in structure; easily manufacture, weight is very little, and cost is very cheap; be well suited for liking swimming and each stratum of other amusements on water and the general population of age bracket, and play very big protective effect just relating to swimming or other amusement on water persons.
Description of drawings
Accompanying drawing is a structural representation of the present utility model;
Below in conjunction with accompanying drawing content of the present utility model is described in further detail.
The specific embodiment
Referring to accompanying drawing.The design comprises: 1, admission port; 2, gas storage air bag; 3, air extractor duct; 4, rigid plastic shell; 5, drain gutter; 6, soft air-guide pipe; 7, the gas valve of controlling by biting force.This device air extractor duct 3 is connected with soft air-guide pipe 6, and soft air-guide pipe 6 is connected with the gas valve of being controlled by biting force 7.
Gas storage air bag 2 is installed in the cylinder type shell 4, shell 4 surroundings are provided with a plurality of apertures 5, and shell 4 is referred to as accumulator unit jointly with gas storage air bag 2, are provided with admission port 1 and air extractor duct 3 in shell 4 and gas storage air bag 2 junctions, air extractor duct 3 is connected by a flexible pipe 6, and the end place connects master cock.The gas valve 7 that described master cock is controlled by biting force constitutes.Described shell 4 is that rigid plastic constitutes.
Principle of work of the present utility model: in gas storage air bag 2, charge into air by admission port 1 with common little inflator before using, air bag can constantly expand along with the increase of gas flow, can observe the degrees of expansion of gas storage air bag 2 by the drain gutter on the rigid plastic shell 45, thereby prevent that the excessive device that causes of air pressure from damaging.After inflation finishes, by braces (not drawing among this figure) carry on the back on one's body, or on one's body other modes are carried on.Gas valve 7 can be contained in the mouth when carrying out aquatic recreational amenities.Sting switch on this valve 7 by mouth when needing, thereby open valve, the gas in the air bag then by air extractor duct 3 through soft air-guide pipe 6 again through valve discharge supply with required.Along with constantly carrying out of using, the gas in the air bag also can reduce thereupon, thereby air bag also can diminish thereupon.So another effect of drain gutter 5 is exactly the inside and outside pressure of balance air bag.
