Bathtub-base inlet, has lower side of upper horizontal channel of stopper is moved up and down, where horizontal channel is immersed in diameter of screw, and bath water flow cross-section is always more sufficient with respect to flow hole
摘要
<p>The inlet (17) has a vertical channel displaced in parallel towards a symmetry line (12) and conforming to an inner diameter of a fitting-fastening hollow screw so as to form a tub (1). A lower side of an upper horizontal channel of a stopper is placed beside a vertical channel and is moved up and down for opening and closing the stopper. The horizontal channel is immersed in the diameter, where bath water flow cross-section is always more sufficient with respect to a flow hole (11), and bath water flows through the upper channel. A security combiner (14) is integrated in the inlet.</p>
