<p>PROBLEM TO BE SOLVED: To provide a medicament mixing mechanism for domestic animals capable of rapidly and reliably mixing a medicament into drinking water for domestic animals.SOLUTION: A medicament mixing mechanism comprises: a medicament introduction pipe line 13 for introducing a medicament from a medicament tank; a medicament lead-out pipe line 14 for discharging the medicament introduced through the medicament introduction pipe line to a drinking water supply pipe; a cylinder part 22 having a function for sucking the medicament from the medicament introduction pipe line and discharging the sucked medicament from the medicament lead-out pipe line; an introduction side non-return valve 31 for accepting a flow of the medicament only in a direction introduced from the medicament introduction pipe line to the cylinder part; and a lead-out side non-return valve 35 for accepting a flow of the medicament only in a direction led out from the cylinder part to the medicament lead-out pipe line. The introduction side non-return valve 31 is formed with a plate-like valve body 32 in contact with a valve seat on the side of the medicament introduction pipe line, and the lead-out side non-return valve 35 is formed with a plate-like valve body 36 in contact with a valve seat on the cylinder side provided in opposing to a lead-out port of the medicament lead-out pipe line. A volume between each non-return valve 31 or 35 and the cylinder part 20 can be made smaller, and a discharge pressure is stabilized.</p> |
