ABSTRACT:
A milking equipment is formed with an electric suction section, a milk sucking section equipped with an open trumpet at its side, and a bottle connected vertically to each other in a manner to effect vertical communication among them. The electric suction section is equipped with a pressure adjusting screw and a pressure releasing button which can freely adjust the internal pressure by intaking the air. The operation of the pressure adjusting unit is easily attained only by holding the equipment with one hand when the milking is performed, and the back flow of the sucked milk toward the suction section is prevented. The equipment works with easy operation, and the suction force to the mother can be changed readily.
