The invention provides an efficient gas conveying structure and a corresponding micro gas pump. The gas conveying structure comprises a gas discharging base, a gas inlet valve body, a ventilation piece, an elastic piece and a driving assembly; a connecting protruding part is arranged on the inner side of the gas discharging base; a cylinder cavity is formed in the gas inlet valve body; an opening connected with the connecting protruding part is formed in one end of the gas inlet valve body, and a gas inlet valve plate is movably arranged at the other end of the gas inlet valve body; the gas inlet valve body is driven by a swing rod assembly so as to press gas in a gas inlet cavity into the cylinder cavity or press gas in the cylinder cavity out into a gas outlet cavity; the ventilation piece is arranged in the cylinder cavity in a sliding manner. A gas conveying channel is arranged on the ventilation piece; a pressed part is arranged on one side of the ventilation piece; the position where the swing rod assembly is closest to the gas discharging base serves as an upper stop position. The elastic piece is arranged between the ventilation piece and the connecting protruding part; and the driving assembly is connected with the gas inlet valve body. The swing rod assembly drives the gas inlet valve body to move, and therefore the ventilation piece can penetrate a gap area to efficiently output gas; and meanwhile, the reverse sealing effect is good, and noise is low.
Description
[0001] This application is a divisional application, the application number of the original application is: "202011479983.3", the application date is: "December 15, 2020", and the name of the invention is: "Micro Air Pump". technical field [0002] The invention relates to the field of air pumps, in particular to an efficient air delivery structure and a corresponding micro air pump. Background technique [0003] Micro air pump refers to a gas conveying device with small size and gaseous working medium, which is mainly used for gas sampling, gas circulation, vacuum adsorption, vacuum pressure maintaining, pumping, pumping, pressurizing and other purposes. At present, there are many kinds of air pumps on the market, which generally include power components, piston cylinder components, intake valve bodies, gas outlet valve bodies and corresponding multiple fixed seats, and the power components are used to drive and control the gas to enter through the intake valve body in one d...
