<p>The present invention relates to an apparatus for driving a breast pump, the apparatus comprising: a housing having an opening formed on the bottom surface; a roller installed in the housing by a rotation shaft such that a portion of the roller protrudes downwards through the opening, wherein the roller rotates due to the friction with the ground; a worm gear fixed to the rotation shaft such that the worm gear rotates together with the roller; a helical gear installed to rotate interlocking with the worm gear, and having a crank shaft which is eccentric from the center of rotation; a crank arm coupled with the crank shaft via a hinge; a piston coupled with the crank arm via a hinge; and a cylinder installed such that the piston reciprocates inside the cylinder, wherein the vacuum pressure generated by the piston is supplied to the outside through a supply hole. According to the present invention, the roller is rotated by friction through only the reciprocation of the roller, and the rotation force of the roller is transmitted to the piston through the gear and the crank to generate a vacuum pressure from the cylinder, thereby pumping breast milk even without using electricity and thus suppressing the strain on the fingers or hand of the mother, simplifying the rotation force transmitting structure for generating the vacuum pressure, accurately transmitting the rotation force, and having excellent operating reliability and durability.</p> |
