The design people provides a kind of " portable swimming safety device for life-saving " at application number in for 85205258 patent specification, and this device performance is perfect, and is safe and reliable, and use in the waters that is adapted at various danger.But China is a developing country, and some people wishes to swim safety device except necessary cheapness, inflation use repeatedly easily voluntarily.Though " portable swimming safety device for life-saving " also can inflate use repeatedly, in addition Change connects the tube core of several maos each time.In the application number that Patent Office of the People's Republic of China announced is 85202758 " inflating swimsuit automatically ", narrated and a kind ofly reacted the technology that acetylene is aerated the interlayer vest that produces with calcium carbide and water, this technology is also easier, material is cheap and easy to get, has closed practicality at certain Games.But this technology exists several like this problems: the first, and calcium carbide is very easily to absorb water in air part and rotten active substance, the user is difficult in use judge whether it is rotten; The second, except explosive reaction, general chemical reaction produces gas, and Enough is not fast, and calcium carbide is the same with sour aerogenesis with water and bicarbonate must to have the sufficient Enough time just can react completely; The 3rd, must there be many calcium carbides of sufficient Enough and water could produce the gas that sufficient Enough measures, certainly will increase the volume of this device like this; The 4th, shape ， And and user's head position that this technology can only be made swimsuit must be higher than the foot position, otherwise shipwreck reacts completely to flow into to make in the calcium carbide.

The utility model proposes a kind of simple swimming safety device, can make the swimmer can Enough easily self-inflating go in the container, thereby make this safety device can Enough easily repeatedly inflation use.

Identical (but sequence number differences) used such as easy liquefied gas, container and hose band that the utility model is used with " portable swimming safety device for life-saving ".As the butane gas that first-selection is used, except originating easily, also safer owing to using.Having investigated a large amount of butane gas lighter ， Bing No that use both at home and abroad has what big safety misadventure took place, and uses just safer under water.25 ℃ under water, the butane of 20 grams Calipering in second more than 10 Yi is inflatable to go into life jacket and makes the people obtain the buoyancy of sufficient Enough.

As shown in Figure 1, easily liquefied gas is contained in the container (14), the turnover tracheae (7) of container has an air inlet/outlet (1), turnover tracheae (7) is entangled by rubber seal (10), it can move up and down, its nearly end portion is made the bigger pallet of diameter (12), pallet (12) is lived by spring (13) institute jacking, make the contact surface of seal ring and pallet air tight, spring (13) is overlapped by inner cover (11) and holds, inner cover (11) can be in various manners (as weldering, riveting, crimpings etc.) be fastened on the wall of container, inner cover (11) is fixed seal ring (10) again and it can not be moved and cooperate with spring and make the contact surface of seal ring and wall of container air tight.The inside and outside gas of inner cover can circulate.Be on seal ring (10) lower surface in the position of air inlet/outlet (1) at ordinary times, like this as long as spring (13) has certain elastic force, easily liquefied gas just can be sealed; And make air inlet/outlet (1) be in seal ring (10) when the lower surface is following when turnover tracheae (7) is pressed down, just can charge into gas or emit container and (14).For turnover tracheae (7) can not collided at ordinary times, can protect it with a mouth mask (9) in turnover tracheae outside, mouth mask (9) is connected on the container.For turnover tracheae (7) is moved down, so that venting or inflation, can adopt several method, simple labour-saving method is used handle (4) and press strip (6) as shown in Figure 1, it is by lever principle, and can adjust the Zhi Chengdian Calipering support shaft holes (5) and the arm of force apart from making its practicality, supporting-point can be a bit, also can be 2 points, can utilize the front and rear wall of mouth mask (9) to make support shaft holes (it is air tight that the eyelet place has seal approach to make).Handle can be straight in the horizontal direction, also can be tortuous (the vertical complications of the direction of arrow are disregarded).If it is straight, then must remove the part of mouth mask wall earlier and (remove seal approach such as partly can adopting rubber or pass in and out tracheae (7) first half by being enclosed within seal ring, seal up in seal ring with outer week and to fix seal ring motionless with the mouth mask internal face, have only the air inlet tracheae to move up and down, it is just air tight like this hose band (8) to be enclosed within mouth mask outside).Handle is put a hole, and latch passes handle hole and holds admittedly on two support shaft holes in front and back.If handle is tortuous in the horizontal direction, then need not latch, directly handle injects on two support shaft holes and need not dig up a part to mouth mask.Press strip (6) is fixed on the handle.Like this, as long as (3) spur handle (4) in the direction of arrows, press strip (6) just presses down turnover tracheae (7) is under the seal ring lower surface air inlet/outlet.In order to make the fixing venting in handle pulling back, can An Zi Lock (2) ， Zi Lock (2) on container also can be positioned on the appropriate location in the mouth mask (9) and match with press strip (6) or other auxiliary members and to work.If without handle and press strip, can be directly past drop-down by variety of way the turnover tracheae with stay cord, also having a kind of method is that mouth mask is become the secondary mouth mask, one-level is fixed on the container, another grade is scalable to be moved, the middle O-ring seals that connects is made degree of tightness and is cooperated, and so just can be directly when pushing scalable mobile mouth mask have pressed down the turnover tracheae is past.In a word, from above-mentioned analysis as can be known, no matter what mode of employing all is in order to make the turnover tracheae move down that the back is fixed and to make air tight.Outside at container (14) or mouth mask (9) is overlapped the hose band of ining succession (8) closely, adopts seal approach at each place, position, hole.This device frenulum on one's body, as long as pulling a handle or a stay cord or push removable mouth mask, it is big that the hose band inflation is risen when feeling danger.One uses up gas can oneself inflate container with supporting standby air bottle again easily, sometimes in order to take off hose band when putting on the air, also can set up the charge valve of a similar butane gas lighter in addition on container.

Also have another kind of method to inflate and venting lifesaving appliance easily repeatedly, the cock switch similar to water tap or gas cooker switch that utilizes container (14) to be installed with exactly, hose band (8) are connected on the switch mouth just rotatable switch it have been inflated.But must be equipped with a charge valve in addition when inflating container (14) is contained on the container.
