DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will describe the present utility model in detail with reference to the accompanying drawings. However, it should be noted that the following content is only for explaining the present utility model and should not be construed as a limitation to the present utility model.

[0024] The following describes the durable high-voltage ceramic discharge device according to an embodiment of the present utility model with reference to the accompanying drawings.

[0025] Specifically, the durable high-voltage ceramic discharge device disclosed by the present utility model can be used on an igniter.

[0026] As Figure 2 and Figure 3 shown, a durable high-voltage ceramic discharge device includes: a ceramic tube 1, on which a plurality of air-permeable and heat-dissipating holes 2 are provided. Among them,

[0027] ceramic baffles 3 are respectively provided at both ends of the ceramic tube 1. An inner fixing bracket 4 is provided on the side of the ceramic baffle 3 close to the ceramic tube 1, and an outer fixing bracket 5 is provided on the side of the ceramic baffle 3 away from the ceramic tube 1. A wire 6 is provided on the outer fixing bracket 5. The inner fixing bracket 4, the ceramic baffle 3, the outer fixing bracket 5 and the wire 6 are sequentially fixedly connected through fixing screws 7;

[0028] A circuit board 8 is provided inside the ceramic tube 1. Two clamping copper parts 9 are provided on the circuit board 8. An electrode 10 is respectively provided on each of the two clamping copper parts 9. The electrodes 10 on the two clamping copper parts 9 are arranged oppositely. The clamping copper parts 9, the circuit board 8 and the inner fixing bracket 4 are sequentially fixedly connected through fixing screws 7.

[0029] Specifically, a plurality of air-permeable and heat-dissipating holes 2 are provided on the ceramic tube 1. The air-permeable and heat-dissipating holes 2 can ventilate, dissipate heat and prevent dust for the ceramic tube 1. Especially the heat generated when the electrode 10 discharges can remove the moisture inside the ceramic tube 1 through the air-permeable and heat-dissipating holes 2, thus playing a role in moisture-proofing;

[0030] On the one hand, the clamping copper part 9 can be used to install and carry the electrode 10, and on the other hand, it can play a role in conducting electricity and dissipating heat;

[0031] The durable high-voltage ceramic discharge device according to an embodiment of the present utility model can be free of a protective gas, is equipped with air-permeable and heat-dissipating holes, has little heat generation during long-term use, can prevent dust and moisture, has a good discharge effect, and has a more beautiful overall appearance.

[0032] In addition, it should be noted that the circuit board 8 is also provided with an elliptical groove-shaped adjustment hole 11 and a circular fixing hole 12. The two clamping copper parts 9 are respectively arranged on the elliptical groove-shaped adjustment hole 11 and the circular fixing hole 12.

[0033] Specifically, the elliptical groove-shaped adjustment hole 11 can be used to adjust the distance between the two clamping copper parts 9, and further adjust the gap between the discharge electrodes 10 on the clamping copper parts 9, so that it can be adapted to thousands of volts of voltage setting up to dozens of kilovolts of voltage.

[0034] Moreover, both sides of the circuit board 8 are tinned.

[0035] Specifically, tinning both sides of the circuit board 8 can weld the clamping copper parts 9, playing a role in secondarily fixing the clamping copper parts 9 and enhancing the electrical conductivity of the clamping copper parts 9.

[0036] It should also be noted that the circuit board 8 is provided with a discharge protection square groove 13, and the discharge electrode 10 is arranged above the discharge protection square groove 13.

[0037] Specifically, the circuit board 8 is provided with a discharge protection square groove 13 below the discharge electrode 10, which can prevent the discharge voltage from being too large, damaging the circuit board 8 or generating black soot and ash to pollute the circuit board 8, avoiding the defect that the glass discharge tube on the market generates black soot and pollutes the glass tube during use.

[0038] In addition, as a possibility, the air-permeable and heat-dissipating holes 2 are 15-degree to 30-degree inclined holes.

[0039] Finally, the surface of the ceramic tube 1 is glazed.

[0040] Specifically, glazing the surface of the ceramic tube 1 can make the entire discharge device beautiful and more easy to maintain.

[0041] In summary, according to the durable high-voltage ceramic discharge device of the embodiment of the present invention, it is not necessary to be filled with a protective gas, it is equipped with air-permeable and heat-dissipating holes, generates little heat during long-term use, can prevent dust and moisture, has a good discharge effect, and the overall appearance is more beautiful.
