[0022] Clearly, the described embodiments are merely part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present utility model.

[0024] Specifically, the upper end surface (i.e. outer end surface or front end surface) of sealing cover 2 is equipped with the ozone exhaust valve 5 being communicated with ozone exhaust outlet 3, the ozone exhaust valve 5 is connected with the ozone pipe 8 outside, so that the ozone in discharge chamber is discharged outward via ozone exhaust outlet 3, ozone exhaust valve 5, ozone pipe 8.

[0025] Preferably, ozone exhaust valve 5 is tower-shaped as a whole with small upper diameter and large lower diameter, the lower part of ozone exhaust valve 5 is provided with threads for threaded connection with ozone pipe 8, by setting ozone exhaust valve 5 with small upper diameter and large lower diameter, the ozone pipe 8 is less likely to fall off under the double force of lower thread and extrusion, thereby improving the connection stability of ozone exhaust valve 5 and ozone pipe 8; in addition, ozone exhaust valve 5 with small upper diameter and large lower diameter has the following beneficial effects: the upper outlet of ozone exhaust valve 5 is small and the internal space is large, forming high pressure, so that ozone exhaust valve 5 can discharge ozone at higher concentration and continuously and stably. Preferably, ozone exhaust valve 5 is integrally formed with sealing cover 2.

[0026] In addition, the middle part of sealing cover 2 can be provided with through hole 6, through hole 6 penetrates the upper and lower end surface of sealing cover 2, the end of enamel pipe passes through the above-mentioned through hole 6, so as to connect high-voltage lead (as high-voltage end) and cooling water pipe at the end of enamel pipe, it can be understood that high-voltage lead is used to apply high voltage to enamel pipe, and cooling water pipe is used to water-cool and heat-dissipate enamel pipe.

[0027] Specifically, the sealing cover 2 is made of insulating material. Preferably, the upper end surface of the sealing cover 2 is provided with an insulating cap 7. It can be understood that the end of the outer shell 1 is provided with a low-voltage end cap bolt for connecting the low-voltage lead, and the upper end of the low-voltage end cap bolt is exposed to the upper end surface of the sealing cover 2. The insulating cap 7 is used to wrap the upper end of the low-voltage end cap bolt. During the ozone generation process, there are several thousand volts of high voltage. If the high-voltage end and the low-voltage end are not isolated, an arc will be generated between the high-voltage end and the low-voltage end, which will cause a fire, a burnt paste, a short circuit and other problems. In addition, when the cooling water temperature is too low, the internal heat is relatively high, and the temperature difference with the outside is too large, which will cause condensation on the surface of the outer shell 1, the sealing cover 2 and other surfaces. The surface with condensation is easy to conduct electricity, which will cause the high-voltage end and the low-voltage end to arc and fire. Therefore, the utility model avoids the high-voltage and low-voltage contact by isolating the high-voltage end and the low-voltage end through the insulating cap 7, so as to better avoid the above-mentioned fire, burnt paste, short circuit and other problems, and better ensure the use safety of the enamel ozone generator. The insulating cap 7 is preferably integrally formed with the sealing cover 2. The number of insulating caps 7 can be eight or the like, which is not limited here.
