A second groove is formed on the outer periphery of the upper edge 7 of the stainless steel outer cylinder body 6, which is provided with a concave groove 3 and an overflow water inlet 5 via a short pipe 4 that is integrally bent outward. It has a screwing part 37 and a bent edge 8 which is integrally bent outward, and has an abutment annular surface 10 that comes into contact with the bent edge 8 and is screwed into the second screwing part 37. A stainless steel annular collar 13 is provided with a third threaded part 11 and several protruding parts 12 bent downward, and an annular stepped part is provided at the lower end of the inner periphery of the upper edge part 7. A stainless steel dust removal flat plate 19 with a large number of small holes 18 is placed on the dust removal flat plate 14, and a stainless steel inverted bowl-shaped body 20 is placed on the lower surface of the dust removal flat plate 19.
is fixed, and the upper end 21 is the lower end 22 of the inverted bowl-shaped body 20.
The outwardly bent lower end edge 23 of the stainless steel odor stopper tube 42 located above is placed on the upper horizontal base 24 of the drain pipe attachment tube 2 of the outer cylinder body 6, and the outer cylinder body 6 and odor The stop tube 42 is welded and fixed via the first welding part 43, and a protruding step 26 is provided on the outer circumference of the stainless steel side connecting tube 25, and the end of the short tube 4 is attached to the protruding step 26. 27 and tightly fit the inner circumferential wall surface 28 of the short tube 4 and the recessed outer circumferential surface 29 of the side connecting tube 25, and the short tube 4 and the side connecting tube 25 are connected at the second welded portion 30. By welding and fixing the joints through the wire, it is possible to firmly protect each connection point from damage over a long period of time, and it is also more resistant to rust, cracks, and cracks than conventionally used castings and synthetic resins.
It can withstand long-term use by preventing the adhesion of dirt, etc., and is easy to attach and detach from the water tank, making it suitable for use in commercial sinks, etc.

In addition, it is convenient to use because overflow water accompanying water storage in the aquarium can easily flow out, or water in the aquarium can be easily drained by removing the airtight lid, and the structure is simple and easy to manufacture. It is easy to provide, can be provided at low cost, is easy to assemble and disassemble, is robust, and can withstand long-term use, and has many practical effects.
