The present invention is applicable to the fields of spraying and chemical agent instruments, and provides a diaphragm pump sprayer comprising a housing in which a battery, a motor and a hose are arranged, with one end of the hose being connected with a sinking water inlet ball and the other end being connected with a spray head, characterized in that: a diaphragm pump for water pumping is also arranged within the housing, one end of the diaphragm pump is connected with the hose and the other end is connected with the spray head, and the diaphragm pump is driven for water pumping by the battery and the motor. The diaphragm pump sprayer provided in the present invention realizes the purpose of pumping and spraying liquid by the diaphragm pump sprayer. The diaphragm pump, which has high chemical corrosion resistance and high working efficiency, is employed as a substitute for existing gear pumps, piston pumps and peristaltic pumps in the present invention.
