Novel semispherical cylindrical stainless steel water cap

The invention discloses a semispherical cylindrical stainless steel water cap, which comprises a filter element (2), a tray (5) and a support rod (6), wherein the support pipe (6) passes through the tray (5) and is dismountably connected with the tray (5) in a sealed mode, the upper end of the filter element (2) is fixed to the upper end of the support pipe (6), and the lower opening end of the filter element (2) is dismountably connected with the tray (5) in a sealed mode. The support pipe, the tray and the filter element of the invention adopt the dismountable fixed connection mode, so the filter element can be conveniently replaced and cleaned, the cost is lower, the materials can be conveniently taken, at the same time, the filter element consists of a semispherical structure and a cylindrical structure, the contact area with target media (water) is enlarged, the system resistance is effectively reduced, the equipment operation pressure is reduced, and the water treatment efficiency is improved.
