<P>PROBLEM TO BE SOLVED: To provide a bubble discharge unit can cleaning a bubbling member made of meshes etc., and also facilitating the operation thereof. <P>SOLUTION: There is provided the bubble discharge unit that includes: a cylinder member B constituted by connecting a large-diameter air cylinder 20 and a small-diameter liquid cylinder 21 vertically; and an operation member C mounted vertically movably in an upward energized state with a discharge head C4 fitted to a stem upper end while the liquid piston C1 is projected from a lower part of an outer periphery of a stem C2, and the air piston C3 is associated with an upper part of the outer periphery of the stem. Then, the bubble discharge unit is configured to bubble a liquid through a bubbling member 76 by mixing the liquid in the liquid cylinder and air in the air cylinder through up/down movement of the operation member and to discharge them from a discharge opening of the discharge head. The discharge head comprises a lower member C4a and an upper member C4b provided with the bubbling member, and there is provided, between both of them, easy separation means including a mechanism for elevating the upper member with respect to the lower member by rotating the upper member with respect to the lower member. <P>COPYRIGHT: (C)2013,JPO&INPIT |
