The specific embodiment

In Fig. 5, rim of a cup 1 links with inflatable structure 2, inflatable structure is made of a plurality of flexible U-shaped pipes, each U-shaped pipe is coaxial radial symmetric arrays, their internal layer is linked to each other by flexible lining, outer continuous by elastomeric material, bottom center intersects, and the inflator 3 with the below links, inflator 3 links by chute 4, spiral pin 5, sealing ring and spring 16 with the mobile base 6 of below, and both can axially slide under external force relatively, in the inboard of inflator 3, combination valve 15 is housed, and this valve is by two check valves and a vent valve, the miniature combination valve that button is formed.The spool of two check valves is respectively inner spool 8 and outer spool 11, they are divided into three chambers with the inner chamber of valve, be inner cavity chamber 7 and middle chamber 10 and chamber, exocoel position 12, outer chamber 12 and atmosphere communicate by the path of button part, inner cavity chamber communicates with the U-shaped pipe by valve 14, and middle chamber communicates with the inflator inner chamber.Button has two stable positions, and one is the inflated condition position, and one is the deflated state position.As shown be inflated condition, when external force makes when moving on the base 6, the inflator inner chamber is compressed, lumen 10 air pressure are increased, and spool 8 moves to left, and lumen 10 is communicated with inner chamber 7, gas is pressed into the U-shaped pipe, and when outwards relatively moving under the effect of mobile base at elastic force, lumen 10 pressure reduce, spool 8 moves to right and resets, close the path of lumen 10 and inner chamber, spool 11 is moved to left, open the path of lumen 10 and exocoel 12, atmosphere is pressed into inflator, finishes inflation.When pressing the button 13, will spool 11 and spool 8 be moved to left successively and open the path of inner chamber 7 and exocoel 12, thereby finish venting.By adjusting set screw 9, can make spool 11 suitable with the interval of spool 8, finish smoothly fill, the venting task.Inflatable structure after the venting is tightened up under the effect of elastomeric material, and is fastening mutually by the locking mechanism of bowl cover and mobile base again.Cup volume after tightening up is fully dwindled.

Fig. 8, among Fig. 9, inflatable structure 1 links to each other with the inflator pump 2 of below, inboard at inflator pump, two miniature position and four-way reversing valves 7 and four are housed are compounded in a check valve of having walked (10～13), four chambeies 14～17 of reversal valve link to each other with the corresponding ports of check valve 10～13 respectively, (chamber 8 and adjacent chamber communicate with atmosphere and other four chambeies of reversal valve 7 communicate in twos with the inner chamber of atmosphere and inflator pump respectively, chamber 18,19 communicate with the inner chamber of inflator pump), the another port of check valve 10～13 respectively with the inner chamber of inflator pump and the inflatable structure inner chamber (check valve 10 that joins, 11 corresponding port communicates with the inner chamber of inflator pump, check valve 12,13 corresponding port communicates with inflatable structure 1 inner chamber by valve 29 and wall interior conduit 20 respectively).21 is a negative one-way valve, and it is positioned at the upper wall of inflator pump, and normality is closed, and opens when inflator pump inner chamber negative pressure reaches a critical point, and 22 for critical pressure adjustment screw, and it can be opened when appropriate negative pressure.In Figure 10, Figure 11, Figure 12, bowl cover is made by permanent-magnet materials, and its Ce is equipped with a check valve 25, and normality is closed, and opens when drawing spool 26 or cup chamber pressure excessive on external force.Rim of a cup 24 is to be made by the metal material of iron family element, and its inwall is equipped with a diaphragm micropump pressure-reducing valve 28 with a voice guard, and communicates with the inner chamber of inflatable structure by the path of rim of a cup inside.Normality is closed, and opens and the warning that pipes when the pressure in the inflatable structure is excessive.During inflation, draw the draw ring on the spool 26 firmly, and with lid-removal, again the button of reversal valve 6 is placed position as shown in the figure, at this moment owing to the pressure of inflator pump inner chamber and inflatable structure inner chamber is born, check valve 11 and 13 successively is opened, and air is by the inner chamber of 19 → chamber, 16 → check valve, 11 → inflator pump inner chamber → chamber, 8 → chamber, chamber, 14 → check valve, 13 → valve, 29 → wall interior conduit, the 20 → inflatable structure 1 of reversal valve.Because the inflator pump chamber pressure increases, spring 5 is flicked by compressive state, and diaphragm and movable base are moved down reduce because the inner chamber of inflator pump increases pressure, air again by chamber 8 by check valve 11, enter the inner chamber of inflator pump, thereby finish intake process.Movable base arrives maximum displacement place, by external force movable base is advanced, compression diaphragm 4, inflator pump inner chamber air pressure is increased, air is finished gas replenishment process by 19 → chamber, chamber, 14 → check valve, the 13 → valve → wall interior conduit 20 of the inner chamber → reversal valve of inflator pump → be pressed into the inner chamber of inflatable structure 1 once more.After inflation makes the chamber pressure of inflatable structure reach certain value repeatedly, pipe by the voice guard of decompression warning combination valve 28, prompting stops to push inflation.After the inflation traveling glass uses up, the water of cup is empty dried, bowl cover is built, again the reversal valve button is pressed, place the negative pressure position, at this moment the passage between the chamber 8 of check valve 10 and reversal valve is opened, and check valve 12 is opened with the passage in chamber 18, and chamber 8 joins with atmosphere, chamber 18 communicates with the inner chamber of inflator pump, because the air pressure of inflatable structure is greater than atmospheric pressure, check valve 12 and 10 successively is opened, and the air of its inner chamber is by 17 → chamber, inner chamber → check valve 10 → chamber, the 8 → atmosphere of 15 → chamber, chamber, the 18 → inflator pump of inner chamber → interior conduit 20 → valve 29 → check valve 12 → reversal valve, after inner and outer air pressure equates, with hand propelled movable base 3, diaphragm 4 is compressed and moves, and the inflator pump cavity volume reduces, pressure increases, check valve 12 is closed, and 10 open, and inflator pump inner chamber air is through the 17 → chamber, chamber of check valve 10 → reversal valve, 8 → atmosphere.Finish exhaust process preceding half section.When the external force that is added on movable base spread disappear after, under the effect of the power of spring 5, diaphragm 4 and movable base 3 outwards slide simultaneously, the chamber pressure of inflator pump is reduced, check valve 10 is closed, 12 open, the inner chamber of 15 → chamber, chamber, the 18 → inflator pump of air → interior conduit 20 → valve 29 → check valve 12 → reversal valve of inflatable structure inner chamber, the second half section of finishing exhaust process.Push movable base repeatedly, above-mentioned exhaust process hockets, thereby make the pressure of the inner chamber of inflatable structure and inflator pump inner chamber more and more negative, after arriving certain value, negative one-way valve is opened, because the inner cavity chamber of cup also seals, negative pressure communicates with it, continue to press and press movable base, the inflatable structure middle part will inwardly constantly be tightened up, the ejection displacement of spring is more and more littler is simultaneously inhaled by negative pressure at last fully, almost can not move, this moment, inflatable structure was tightened up fully, is harmonious from inflation inlet bowl cover and movable base.Finish the negative pressure process.
