A high-pressure pump cooling mechanism

Abstract

The invention relates to the technical field of cooling of inflators and discloses a cooling mechanism for a high-pressure inflator. The cooling mechanism comprises an outer cylinder barrel, an innercylinder barrel, a first-stage compression chamber, an air storage chamber, a pedestal and a third-stage compression chamber; the bottom of the air storage chamber is provided with cooling liquid; thecooling liquid can move with up-and-down movement of the outer cylinder barrel; the inside of the air storage chamber is slidably connected with a liquid isolating plug; the liquid isolating plug ispositioned below the cooling liquid; the inner wall of the inner cylinder barrel is provided with a compensative air channel; the inner wall of the pedestal is provided with an inflating channel; andthe top end of the inflating channel is provided with a one-way pneumatic valve. According to the cooling mechanism disclosed by the invention, the air storage chamber is filled with the cooling liquid so that the high temperature at a third-stage compression cylinder can be transmitted to the inner cylinder barrel in time; the outer wall of the inner cylinder barrel makes direct contact with theatmosphere, so the cooling mechanism achieves a relatively good heat radiation effect, the heat inside the third-stage compression cylinder can be quickly transmitted, and thus the use stability of apiston inside the third-stage compression cylinder can be protected preferably.

Description

technical field [0001] The invention relates to the technical field of air pump heat dissipation, in particular to a high-pressure air pump cooling mechanism. Background technique [0002] The high-pressure pump adopts a three-stage compressed gas sleeve structure, which can realize manual high-pressure inflation, and cooperates with the high-pressure thin tube structure on the upper inner layer, and uses high pressure and low stress area to achieve the effect of small resistance, which can realize labor-saving function and is widely used Used in manual and portable pumps. [0003] Such as figure 1 As shown, the outer cylinder 1 is lifted up to replenish the gas, and then pressed down, the gas enters the first-stage compression chamber 7 through the one-way air intake apron 6, and then the outer cylinder 1 is lifted up, and the one-way air intake apron 6 is blocked The gap between the top cover 5 and the outer cylinder 1, the gas enters the gas storage chamber 8, then ente...
