The detection cavity 61 is arranged on one side of the water inlet channel 64, and the detection cavity 61 is connected to the water inlet channel 64. The sensor assembly 7 is arranged in the detection cavity 61, which can detect the flow rate of water entering the shell 1 for electrolysis, so as to prevent the electrode sheet assembly 3 from dry burning and reducing its life or even being damaged.

[0031] Furthermore, the sensor assembly 7 includes a water flow sensor and a temperature sensor, both of which extend into the water inlet channel 64, and can directly monitor the state of the water flow, making it convenient to maintain the ozone generator.

[0032] Furthermore, the sensor assembly 7 also includes an adapter plate 72, which is fixed in the detection cavity 61. The water flow sensor is connected to the adapter plate 72. The adapter plate 72 is provided with a terminal connected to the external controller. The controller is connected through the terminal. The sensor assembly 7 and the water inlet structure 6 can be replaced at the same time and can be quickly replaced after damage.

[0033] Preferably, a protruding groove is provided on the side wall of the water inlet structure 6, and the groove serves as a detection cavity 61 for placing the sensor assembly 7. A pillar 71 is provided on the side wall of the groove, and an adapter plate 72 is fixed on the pillar 71 to improve the installation stability of the adapter plate 72.

[0034] Furthermore, an opening is provided at the top of the detection cavity 61, and a convex ring 73 is provided on the edge of the opening. The water inlet structure 6 also includes a top cover (not shown in the figure), which is snapped onto the opening to close the sensor assembly 7.

[0035] Furthermore, an electrolysis chamber 11 and an electrode chamber 12 are provided in the shell 1. The electrode chamber 12 is arranged above the electrolysis chamber 11. The electrode chamber 12 penetrates the top wall of the shell 1 to form a through hole. The end cover 2 is arranged on the through hole.

The first sealing gasket 41, the first elastic element 43 and the second sealing gasket 44 are sequentially mounted on the anode column 42. The first elastic element 43 applies pressure to the anode column 42 toward the electrolysis chamber 11. A first retaining ring is provided in the middle of the anode column 42.

[0039] Preferably, a side cover is further included, which is detachably connected to one side of the shell 1. The side cover is provided with a water inlet, and the opposite end of the shell 1 is provided with a water outlet for connecting to an external water supply and water outlet circuit.

The two sides of the electrode sheet assembly 3 are respectively clamped in the groove 14. The protrusion 13 is below the electrode sheet assembly 3. There is a gap between the top of the protrusion 13 and the electrode sheet assembly 3, which can prevent the electrode sheet assembly 3 from bending and deforming downward and falling, thereby ensuring the stable and efficient operation of the electrode sheet assembly 3. The groove 14 is composed of two ribs extending from the side wall of the electrolysis chamber 11. The electrode sheet assembly 3 is clamped by the two ribs, which plays a role in supporting the electrode sheet assembly 3.

[0044] Preferably, the shell 1 also includes a sealing groove 15, which is arranged on the bottom wall of the electrode cavity 12.
