Problems solved by technology

[0002] The airflow generated by the existing manual air pump is high-pressure translational airflow. This kind of air pump operates smoothly due to the low pressure value inside the inflated object at the initial stage of inflation, but when the air pressure value inside the inflated object is close to When saturated, the user must exert more force to overcome the resistance of the above pumping

Abstract

The invention discloses a manual vortex air pump, which comprises an air cylinder, a piston, and a piston rod; the piston is arranged in the air cylinder, and the lower surface of the piston is an impeller structure; the piston rod is fixedly connected to the piston, and the outside of the piston rod is a spiral structure. The structure of the guide hole in the cap matches the helical structure of the piston rod. When the piston rod passes through the guide hole, the guide hole and the piston rod cooperate to drive the piston rod to rotate, and the gas under the piston is compressed into a high-pressure vortex flow, which Compared with the high-pressure translational airflow, it has greater penetrating power, is easier to overcome the obstruction of air pressure, and saves effort to inflate the object to be inflated.

Description

technical field [0001] The invention belongs to the technical field of inflation, in particular to a vortex airflow manual pump. Background technique [0002] The airflow generated by the existing manual air pump is high-pressure translational airflow. This kind of air pump operates smoothly due to the low pressure value inside the inflated object at the initial stage of inflation, but when the air pressure value inside the inflated object is close to When it is saturated, the user must exert more force to overcome the resistance of the above-mentioned pumping. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the invention provides a vortex airflow manual pump. [0004] The technical solution adopted in the present invention is: a manual air pump with vortex air flow, including an air cylinder, a piston, and a piston rod; [0005] The gas cylinder is hollow cylindrical, with an open upper end and a closed lower end. A cap is provide...
