<p>PURPOSE:To enable the bleading of air with a simple construction and operation by arranging in air bleeding valve interlocking a switch in a waveguide to open the air bleeding valve when the switch is turned OFF. CONSTITUTION:A cylindrical cock inserting section 22b is erected on the top surface of a subcase 22 communicating with an upper liquid guide path 22a and an air bleeding hole 22c is opened at a lower side thereof while a feed liquid hole 22d at an upper side thereof. The air bleeding hole 22c is arranged at a position turned by about 120 deg. with respect to the feed liquid hole 22d and a plurality of openings 22e are arranged on the subcase 22. When a knob 30 is turned clockwise, the air bleeding hole 22c is closed with an outer circumferential surface of a cock 24 to make the feed liquid hole 24d communicate with the feed liquid hole 22d. On the other hand, a magnet holder 28 also turns and a ferrite magnet 29 approaches a lead switch 15 to turn ON a motor M and as a screw 20 turns, a vortex is generated in a pump chamber 19 and a cleaning liquid is sent into a lower waveguide 19b. Then, it passes through the upper waveguide 22a and the cock 24 and then, through feed liquid holes 24c and 22c to be fed to a cleaning tube.</p> |
