Electric pump structure

The invention relates to the field of electric equipment, and particularly discloses an electric pump structure which comprises a pump body, a piston arranged in the pump body, shells arranged at the two ends of the pump body and elastic diaphragms installed in the shells. A medium leading-in port and a medium leading-out port which are communicated with an inner cavity of the shell are formed in the two sides of the shell respectively, a one-way leading-in interception assembly is arranged at the medium leading-in port, and a one-way leading-out interception assembly is arranged at the medium leading-out The electric pump structure further comprises a reciprocating driving assembly, the reciprocating driving assembly is connected with the motor and suitable for controlling the piston to reciprocate, and the piston controls the elastic diaphragm to expand and contract in the inner cavity of the shell. When the motor rotates at high frequency, the piston in the pump body can correspondingly perform high-freque
