When the anode member 220 and the cathode member 230 are arranged opposite to each other, the contact area with the electrolyte is larger, so that the electrolytic reaction speed of the anode member 220 and the cathode member 230 can be improved, but oxygen is mainly generated by being concentrated on the anode member 220, if the anode member 220 is completely arranged on one vertical side wall of the reaction chamber 211 like the cathode member 230, the oxygen generated on the anode member 220 needs to be separated from the upstream of the anode member 220 to the electrolyte and then discharged from the gas outlet 214 at the top of the reaction chamber 211, so that the discharge of the oxygen is not smooth enough, and even enters the liquid storage chamber; therefore, the gap 221 is formed at the position where the top of the anode 220 is attached to the top surface of the reaction member, so that oxygen on the anode 220 can rapidly flow to the gap 221 along the anode 220, then enter the exhaust pipe 270, and finally be exhausted from the exhaust port 214.
The exhaust pipe 270 and the handle 280 are respectively positioned at two opposite sides of the electrolytic cell body 210; the position limiting recess 130 includes a first recess 131 and a second recess 132; the first recess 131 and the second recess 132 are respectively located at two opposite sides of the cartridge body 110, the first recess 131 corresponds to the exhaust pipe 270, and the second recess 132 corresponds to the handle 280.

The sealing cover 272 is mounted on the exhaust pipe 270 by adopting a snap structure, and the snap structure is located outside the exhaust pipe 270, so that the side surface of the exhaust pipe 270 cannot be stably and tightly mounted with the vertical side surface of the first concave part 131, and the limiting effect of the limiting structure cannot be ensured; after the convex edge part 274 is additionally arranged outside the exhaust pipe 270, the convex edge part 274 can be stably attached to the vertical side surface of the first concave part 131, and meanwhile, the exhaust pipe 270 and the sealing cover 272 can be accommodated in the first concave part 131, so that the limiting effect of the limiting structure is guaranteed; in addition, the rib 274 can also reinforce the vertical sidewall of the exhaust pipe 270, so as to prevent the exhaust pipe from being easily damaged due to too long extension; of course, in order to further increase the connection strength between the bottom of the exhaust pipe 270 and the reaction chamber 211, a reinforcing rib 275 may be additionally provided at the connection position to enhance the structural strength.

When oxygen generated in the reaction chamber 211 enters the exhaust pipe 270, the oxygen often carries a certain amount of vaporized electrolyte, and if the oxygen carries the electrolyte to be exhausted from the exhaust port 214, on one hand, the electrolyte is consumed too fast, the oxygen generation use cost of the oxygen generation device 10 is increased, and the replacement operation of the electrolyte box is too frequent; on the other hand, when the oxygen generator 10 is applied to the air conditioner indoor unit 20, the air blown out by the air conditioner indoor unit 20 also contains electrolyte components, which causes indoor air to be polluted; after the waterproof breathable film 271 is additionally arranged in the exhaust pipe 270, the waterproof breathable film 271 can filter substances such as vaporized electrolyte in flowing oxygen, so that the oxygen discharged from the exhaust port 214 is cleaner; in addition, after the electrolyte attached to the surface of the waterproof breathable film 271 reaches a certain concentration, the electrolyte can flow back into the reaction cavity 211, so that the consumption of electrolysis is reduced, and the use cost of oxygen generation is reduced.
