The invention relates to composite liquid pumping equipment, the characteristic is in that: 1. on the bottom of liquid pipe of hand-pressing pump provides with an electric liquid pumping equipment, the outlet of the electric pumping equipment could be connected to the lower end of the pipe of hand-pressing pump so as to form a liquid communicating structure; 2. Hand-pressing air compressing ball could be provided in a suitable position of the top end or side end of composite liquid pumping equipment of the invention in order to match the configuration, structure and convenience of the product; if hand-pressing air compressing ball is disassembled, an electric one could be used also to generate liquid pumping effect; however, whether the hand-pressing air compressing ball is disassembled or not, pumping liquid effect could be generated by the electric liquid pumping equipment of the invention without any influence; 3. The motor in the liquid pumping equipment could be provided in the power-supplying house or in a suitable position of liquid pumping pressure chamber, the spiral vane or stirred component of other structure could be fixed by means of a shaft with cylindrical shape.
