A support edge 16 made of stainless steel is attached to the lower portion of the 14, which is bent inward and has an L-shaped cross section with several cut and raised pieces 15, 15.
5, 15 and an outer locking edge 17 that rests on the support edge 16, and a stainless steel inverted bowl on the lower surface of the stainless steel dust collection case 19, which has a large number of small holes 18. The shaped body 20 is fixed, and the upper end 2
1 is located above the lower end 22 of the inverted bowl-shaped body 20, and the outwardly bent lower end 23 of the stainless steel odor stopper pipe 44 is attached to the upper horizontal base 24 of the drain pipe attachment pipe 2 of the outer cylinder body 6. Place the outer cylindrical body 6 and the odor stopper tube 4.
4 are welded and fixed via a first welding part 46, and a protruding step part 26 is provided on the outer periphery of the side connecting pipe 25 made of stainless steel, and the end part 27 of the short pipe 4 is attached to the protruding step part 26. The inner circumferential wall surface 28 of the short tube 4 and the recessed outer circumferential surface 29 of the side connecting tube 25 are tightly fitted together, and the short tube 4 and the side connecting tube 25 are connected to the second welded portion 30.
By welding and fixing the joints, 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 dirt adhesion than conventionally used castings and synthetic resins. It can withstand long-term use, 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.
