The specific embodiment

Referring to Fig. 1 to Fig. 4, present embodiment is made up of body 4 and vacuum pump head, is provided with flexible pipe button bit 403 at the head inwall of body 4, and tube head 402 in being provided with within the head of body 4 is provided with flexible pipe fluid hole 401 at the top of interior tube head 402; Head at body 4 is connected with the vacuum pump head, and described vacuum pump head comprises head 1, elastic body 2 and airtight valve 3, and elastic body 2 adopts thermoplastic elastomer or silica gel elastic body.

Referring to Fig. 2 to Figure 11, head 1 is provided with horizontal head fluid hole 101 at the top; On the outer wall of head 1, be provided with head button bit 103 and cooperate the effect of playing location head 1 with flexible pipe button bit 403; Central interior at head 1 is provided with head sealing column 106, be provided with first seal ring 105, second seal ring 102 in the periphery of sealing column 106, the lower end of sealing column 106 stretches in the flexible pipe fluid hole 401, and is provided with head buckle 104 in the bottom of sealing column 106 and matches with airtight valve 3 and be connected; Airtight valve 3 cooperates with the top inner wall of interior tube head 402 and plays sealing function; Elastic body 2 is the hollow column type, within its top 201, be provided with seal ring 202, elastomeric top 201 and seal ring 202 are between first seal ring 105 and second seal ring 102 of head 1, and respectively with second seal ring 102 of head 1, first seal ring 105 cooperates and play sealing function, head fluid hole 101 is communicated with the cavity between vacuum pump head outside and elastomeric top 201 and its seal ring 202, be provided with elastomeric seal post 203 in the bottom of elastic body 2 and be enclosed within outside the head sealing column 106, both play sealing function at cooperation.

Principle of the present utility model is as follows: after pressing head 1, airtight valve 3 moves down, no longer be sealed and matched with the top inner wall of interior tube head 402, flexible pipe fluid hole 401 is opened, the effect of pressure is simultaneously opened elastomeric top 201 and seal ring 202, flow of liquid in the cavity between elastic body 2 and head sealing column 106 flows out from head fluid hole 101 through to the cavity between elastomeric top 201 and the seal ring 202 again; The cavity that liquid flows out between back elastic body 2 and the head sealing column 106 is vacuum state at this moment; when head 1 resets because the pressure effect; liquid are through flexible pipe fluid hole 401, flow to elastomeric seal post 203 again in the body 4; the effect of suction is opened elastomeric seal post 203 to flow to the cavity between elastic body 2 and the head sealing column 106; thereby form circulation; airtight valve 3 rises and cooperates with the top inner wall of interior tube head 402 again; closed hose fluid hole 401, its content can not be extruded out and play a protective role during extruding body 4.
