The specific embodiment
Introduce the specific embodiment of a kind of bottle stopper of the utility model below in conjunction with accompanying drawing, but it may be noted that the enforcement of the utility model is not limited to following embodiment.
Can know that with reference to figure 1 a kind of bottle stopper comprises main body 1, expansion loop seat 4, expansion loop 5, spring 3 and briquetting 2.Be provided with the cavity 6 and first through hole 10 in the main body 1, and first through hole 10 is connected with cavity 6.Briquetting 2 comprises cylinder 201 and lower prop 202 two parts, and is provided with a closed-loop 12 at cavity 6 opening parts of bottle stopper main body 1, and the inside radius of closed-loop 12 is greater than last cylinder 201 radiuses, and less than lower prop 202 radiuses; Briquetting 2 lower props 202 are positioned at cavity 6 upper ends, and closely contact with cavity 6 perisporiums, and cylinder 201 exposes outside bottle stopper on the briquetting 2; An end opening of second through hole, 7, the second through holes 7 that is provided with inverted "L" shaped in the briquetting 2 is at lower prop 202 lower walls, and other end opening is at briquetting 2 sidewalls.Expansion loop seat 4 upper ends clog cavity 6 lower ends, and closely contact with cavity 6 perisporiums, and expose below main body 1 lower end; Be provided with the third through-hole that is connected 8 and fourth hole 9 in the expansion loop seat 4, third through-hole 8 is axially extending bores, fourth hole 9 be with axial vertical direction on through hole, two exits of fourth hole 9 are surrounded by expansion loop 5 respectively; Said expansion loop 5 is a hollow hemisphere, is processed by rubber, and this spheroid opening part and fourth hole 9 exits are tightly connected.Spring 3 has two, all be located in the space that expansion loop seat 4 upper walls and lower prop 202 lower walls surround, and spring 3 two ends respectively with expansion loop seat 4 upper walls and lower prop 202 lower wall Joints.The axis of said cavity 6, briquetting 2, expansion loop seat 4 all is located along the same line.
The purpose that closed-loop 12 is set is the displacement in the axial direction of restriction briquetting 2; Avoid because steam air pressure increases sharply suddenly; When expansion loop 5 did not also have enough time to expand, the power that steam imposes on briquetting 2 had surpassed the power that spring 3 can bear, and makes that briquetting 2 is ejected.
