    • A milking apparatus includes a bottle for storing drawn mother's milk, a milking section to be pressed against the mother's breast, and a suction portion including a suction generating section, for generating a suction in the bottle, and a pressure adjusting mechanism for adjusting the amount of suction. The pressure adjusting mechanism and the suction generating section include an attaching body formed with an open-air introducing hole, a compression coil spring, a valve rod having a tapered surface, a diaphragm having a valve seat adapted to closely contact with the tapered surface, a cap cooperating with said diaphragm to define a suction chamber therebetween, a pressure releasing push button having a cam surface and adapted to arrest the valve rod, and a pressure adjusting knob for applying a pressing force to the cam surface of said push button. Further, the milking apparatus includes a dome-shaped cup with a collar interposed between the bottle and the milking portion with its vertex facing downward. The collar is provided with a plurality of suction holes for communication betwen the bottle and milking portion, and a through hole is formed in the vertex A non-return valve which is normally open is disposed at the communicating portion betwen the bottle and milking protion.
    • 挤奶装置包括:用于储存拉伸母乳的奶瓶,压靠母乳的挤奶部分;以及吸引部,其具有用于在瓶中产生吸力的吸引产生部,以及用于调节量的压力调节机构 的吸力。 压力调节机构和吸入发生部分包括形成有露天引入孔,压缩螺旋弹簧,具有锥形表面的阀杆的安装体,具有适于与锥形表面紧密接触的阀座的隔膜, 与所述隔膜协作以在其间限定吸入室的盖,具有凸轮表面并适于阻止阀杆的压力释放按钮,以及用于向所述按钮的凸轮表面施加按压力的压力调节旋钮。 此外,挤奶装置包括圆顶形杯,其具有插入瓶和挤奶部之间的轴环,其顶点面向下。 套环设有多个用于在瓶子和挤奶部分之间连通的抽吸孔,并且顶点形成通孔。常开的止回阀设置在瓶子和挤奶部分之间的连通部分。

    • 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.
    • 挤奶设备形成有电抽吸部分,在其侧面配备有开口喇叭的奶吸部分和以垂直方式彼此垂直连接的瓶子。 电动吸气部分配有压力调节螺钉和压力释放按钮,可通过吸入空气自由调节内部压力。 只有通过在挤奶时用一只手握住设备,并且防止吸入的牛奶向抽吸部分的回流而容易地实现压力调节单元的操作。 设备操作简单,对母亲的吸力可以轻松改变。
