Claims

[Claims for Utility Model Registration] (1) A container 7 equipped with a negative pressure supply port 2, a chemical solution suction port 4, and a chemical solution supply port 6; In a chemical solution supply device for a milking machine, which includes an upper valve 25 that closes the supply port 2 and a lower valve 9 that closes the drug solution supply port 6 due to a pressure difference between internal pressure and atmospheric pressure, the container 7
is a cylindrical upper container 12 and a replaceable lower container 13
The float 8 is formed into a cylindrical shape leaving a small gap 21 between it and the upper container 12, and a stopper 16 is provided at the lower end of the upper container 12 to support the bottom of the float 8. Chemical solution inlet 4
A drug solution supply device for a milking machine, characterized in that it is provided with a constriction portion 33 that opens toward the inner wall surface of an upper container and restricts the flow of the drug solution to be inhaled. (2) The chemical solution supply device according to claim 1, wherein a small hole 29 is provided on the negative pressure source 1 side from the closed position 28 by the upper valve 25 of the negative pressure supply port 2 to communicate the negative pressure supply port 2 with the atmosphere. . (3) The chemical solution supply device according to claim 1 or 2, further comprising a small hole 30 that communicates the inside of the container 7 with the atmosphere on the side of the container 7 from the closed position 28 of the negative pressure supply port 2 by the upper valve 25.
