The invention discloses a high-pressure large-flow electric pump, and aims to overcome the defects that many electric pumps used at present can only meet the single requirement of large-flow air inflation or high-pressure air inflation, and the air inflation effect is poor. The invention comprises: an upper air chamber in which a centrifugal impeller is mounted; a closed impeller is mounted in the lower air chamber; a vortex air chamber; the centrifugal impeller and the closed impeller are mounted on an output shaft of the motor; a transition flow channel is arranged between the upper air chamber and the lower air chamber, a drainage air channel is arranged between the lower air chamber and the vortex air chamber, and the drainage air channel is arranged in a downward inclined mode in the circumferential direction. According to the high-pressure and high-flow electric pump, stable high-pressure and high-flow inflation can be achieved. 本发明公开了一种高压大流量电泵，旨在解决目前使用的很多电泵只能满足大流量充气或高压充气的单一要求，充气效果不佳的不足。该发明包括：上气室，其内安装离心
