And, between the anode of anode material water water tank and ozonizer, be equipped with heat exchanger between the negative electrode of cathode materials water water tank and ozonizer.

And cathode materials water water tank is communicated with anode material water water tank by check valve, but the water anode raw water water tank in the cathode materials water water tank is flowed.

As shown from the above technical solution, ozonizer in the utility model is in series by the multipole plate by two or more unit electrolytic baths, placed in-line unit electrolytic bath is many more, the output of ozone is just big more, because the anolyte compartment of unit electrolytic bath, be respectively equipped with porous conductor in the cathode compartment, porous conductor can play conduction simultaneously, the effect of water conservancy diversion and heat radiation, but make its internal heat dissipating and need not the peripheral hardware radiating block, thereby reduced the volume of whole device, again because of the anode material water input hole of each unit electrolytic bath of constituting ozonizer, anode material water and product output channel hole, cathode materials water input hole, cathode materials water and product output channel hole are corresponding respectively to be communicated with, the service pipe of ozonizer all is positioned at the inside of ozonizer like this, make the structure of ozone generating-device very compact, the peripheral hardware pipeline also seldom, also reduce the energy loss in the device simultaneously, reduced production cost.
