The invention provides a multistage series-parallel connection combined diaphragm pump which comprises a plurality of pump head units, each pump head unit is provided with an air suction port and an air exhaust port, and the pump head units are connected with one another through air pipes to form an air channel, so that series connection and parallel connection are formed; in the multiple pump head units, at least two pump head units are connected in parallel, the other pump head units are connected in series, in the pump head units connected in parallel, air suction ports of the multiple pump head units are connected through air pipes to achieve parallel connection, and air exhaust ports of the multiple pump head units are connected through air pipes to achieve parallel connection; the exhaust port of the pump head unit located at the front end is connected with the air suction port of the adjacent pump head unit located at the rear end through an air pipe to achieve series connection. The multiple pump head
