A central partition is arranged in the middle of the interior of a housing; a first N-pole energy conversion block is connected to the inner wall of a left side edge of the housing; a second N-pole energy conversion block is connected to the inner wall of a right side edge of the housing; a first L-pole energy conversion block is connected to a lower left edge of the central partition; a second L-pole energy conversion block is connected to an upper left edge of the central partition; a third L-pole energy conversion block is connected to a lower right edge of the central partition; and a fourth L-pole energy conversion block is connected to an upper right edge of the central partition. The quick ionized water structure has the following beneficial effects: the plurality of energy conversion blocks are arranged to improve the energy conversion effect; clearance grooves are formed between the energy conversion blocks; water flowsinto gaps; as a first clearance groove, a second clearance groove and a third clearance groove are wavy, the lift of the clearance grooves is increased, the water inflow time is prolonged, and the heating efficiency is improved; and the quick ionized water structure is simple, safe and reliable.
