The invention has the beneficial effects that:

1. when the liquid in the liquid-gas separation cylinder is pumped by the delivery pump and discharged into the supporting pipe and discharged through the speed increasing pipe, the liquid generates a Venturi effect after flowing through the speed increasing pipe by the conical structure of the speed increasing pipe so as to increase the flow speed, so that low pressure is formed near the high-speed flowing liquid and an adsorption force is generated to act on the one-way valve so as to suck external gas into the supporting pipe and discharge the external gas into the liquid-gas separation cylinder along with the liquid, the liquid-gas separation cylinder is discharged outwards after liquid-gas separation, and the air pump operates by utilizing the Venturi effect, thereby avoiding the operation of driving a piston to compress the gas, reducing the noise and improving the use quality;

when the supporting pipe absorbs external air and discharges the external air into the liquid-gas separation cylinder along with liquid, the mixture of the liquid and the gas impacts the liquid-gas separation cover, the liquid is downwards scattered after impact so as to separate the liquid from the gas, and the discharge path of the liquid is prolonged when the liquid is downwards scattered so as to ensure that the liquid is more thoroughly separated from the gas, after the liquid-gas separation, the gas upwards floats and is discharged through the exhaust pipe so as to ensure that the air pump runs, and the liquid drops to the bottom of the liquid-gas separation cylinder for storage and is transported by the transport pump so as to ensure that the air pump continuously runs, so that the use is smoother;

2. the air pump is when using, through placing the casing in suitable position and make bottom and holding surface contact, the casing protects liquid-gas separation jar and support shell etc. and avoids it impaired, and the circulation mouth switches on casing and external environment, and make things convenient for the check valve to extract external gas and make the air pump work, and the air pump is when the work operation, the produced vibrations of shear thickening liquid to air pump work in the shock attenuation shell absorb the consumption, thereby the heelpiece plays the cushioning effect equally simultaneously and makes air pump work more smooth and easy reliable.
