The specific embodiment

Referring to Fig. 1 and Fig. 2, the flexible pipe of present embodiment is made up of head 1, elastic body 2 and body 3.

Referring to Fig. 1, Fig. 2, Fig. 4 and Fig. 5, on the top inwall of the head 302 of body 3, be provided with body button bit 301, interior middle position at body head 302 is provided with drain pipe 303, drain pipe 303 is connected with body head 302 one in the bottom, be connected with fluid hole supporter 304 at the top of drain pipe 303, and between drain pipe 303 and fluid hole supporter 304, be provided with the body fluid hole.

Referring to Fig. 1, Fig. 2, Fig. 6 and Fig. 7, be provided with head fluid hole 101 in the side of head 1, be provided with head button bit 103 in the bottom of head 1, thereby head button bit 103 is interlockingly connected with body button bit 301 head 1 and body 3 is linked together, be provided with head seal ring 102 in the inside of head 1, be provided with three grooves 104 in the bottom of head seal ring 102.

Referring to Fig. 1, Fig. 2 and Fig. 8, elastic body 2 is a thermoplastic elastomer, it comprises the inboard elastic body inwall 203 and the elastic body gear 202 in the outside, and elastic body inwall 203 is connected in the bottom one with elastic body gear 202, is provided with elastic body fluid hole 201 in the center of top of elastic body inwall 203; Elastic body 2 is contained in the head 1, thereby head seal ring 102 matches with the space between elastic body inwall 203 and the elastic body gear 202 head 1 and elastic body 2 is linked together, do not push under the situation of head there being pressure, between the top of the top of elastic body inwall 203 and elastic body gear 202 and head 1, form first chamber 4 and second chamber 5 respectively, elastic body inwall 203 and elastic body gear 202 closely are wrapped on the head seal ring 102, guaranteed the sealing state in first chamber 4, promptly guarantee the vacuum in first chamber 4 and prevented the pollution that air circulation causes, elastic body inwall 203 is enclosed within on the fluid hole supporter 304, and elastic body fluid hole 201 is less than the top of fluid hole supporter 304.

Referring to Fig. 2 and Fig. 3, the use and the principle of present embodiment are as follows: present embodiment is in body 3 behind the enclosing liquid, because first chamber 4 is a vacuum, liquid in the body 3 will push the top of elastic body inwall 203 after the body fluid hole flows out, again in elastic body fluid hole 201 flows out to first chamber 4, after pressing head 1, the bottom of head seal ring 102 presses down and makes elastic body 2 downward tensile deformations, liquid in first chamber 4 pushes elastic body inwall 203 and elastic body gear 202 under pressure, and the groove on head seal ring 102 104 flow to second chamber 5, flow out from head fluid hole 101 again, flexible pipe this moment state as shown in Figure 3, because elastic body fluid hole 201 is less than the top of fluid hole supporter 304, after pressing head 1, the liquid that can not in first chamber 4 is back in the body 3; It is vacuum state that liquid flows out first chamber 4, back, and owing to atmospheric effect, the liquid in the body 3 flowed to first chamber 4 again when head 1 resetted, and so forms circulation.
