More Information
Summary:The utility model relates to the technical field of air pumps, and discloses a portable air pump which comprises a shell, a one-way air inlet valve used for air inflow in the shell is fixedly connected to the outer portion of the shell, and a noise reduction nozzle used for noise reduction when air flows into the one-way air inlet valve is fixedly connected to the outer portion of the one-way air inlet valve. The screw rod rotates to enable the air compression disc to slide in the shell in a reciprocating mode, the air compression disc slides in a reciprocating mode to enable air to be silenced through the silencing nozzle and flow into the shell through the one-way air inlet valve, and the air compression disc compresses air and then is exhausted through the one-way air outlet valve. The lead screw and the air compressing disc are matched with the silencing nozzle, the one-way air inlet valve and the one-way air outlet valve, so that the size and the weight of the air pump can be effectively reduced, and the
