The invention discloses an ozone electrolysis chamber, comprising a shell, wherein a water inlet and a water outlet are respectively formed in two ends of the shell; an inner cavity of the shell is anelectrolysis cavity; at least one electrode plate seat is arranged in the electrolysis cavity; at least one group of electrolysis assembly is arranged on the electrode plate seat; each electrolysis assembly comprises an anode plate, a proton exchange membrane and a cathode plate; a water passing seam is reserved between the electrolysis assembly and the inner wall of the electrode plate seat; first water passing holes are formed in the anode plate; second water passing holes are formed in the proton exchange membrane; an elastic component with the two ends abutting against the cathode plate and the inner wall of the shell respectively is arranged in the electrolysis cavity; and one side of the bottom of the electrode plate seat faces the water inlet. The ozone electrolysis chamber is goodin heat dissipation performance, the service life of the electrode plates is long, the concentration of generated ozone water is high, and incrustation accumulated on the surface of the electrode plates can be avoided. The invention further provides an ozone electrolysis chamber application module which can generate large-flow high-concentration ozone water in a short time and is extremely wide in application range.

The invention discloses a compact hydrogen-oxygen generator. On a fluid channel, a water circulation outlet of a water box communicates with a water pump through a one-way throttle valve, the water pump communicates with a hydrogen-oxygen generator electrolytic bath, the hydrogen-oxygen generator electrolytic bath communicates with a water circulation inlet of the water box through another one-waythrottle valve, and a gas outlet of the water box communicates with an engine inlet body through a steam-water separation device and a dry type flame arrester in sequence; on a circuit, the water pump and the hydrogen-oxygen generator electrolytic bath are connected to the positive pole end and the negative pole end of a vehicle power source in a parallel connection mode; and a switch, a fuse andthe hydrogen-oxygen generator electrolytic bath are connected with the vehicle power source in a series connection mode. According to the compact hydrogen-oxygen generator, through the compact designthat a porous electrode bar and a stainless steel sleeve are closely nested, efficient electrolysis is achieved, on the premise that the gas production quantity is met, the size and weight of the electrolytic bath are decreased, assembling of a single electrolytic chamber of the on-board hydrogen-oxygen generator is achieved, the hydrogen-oxygen generator is directly connected with the single sealed electrolytic chamber in the circuit and the fluid channel, and the problems caused by series connection of multiple electrolytic chambers are effectively solved.
