Then, the conductive pin 6 on the end seat 5 is electrically matched with the power line 4, and the trigger wire 20 is extended to the outside of the outer lamp tube 1 through the end seat 5 at one end, so that the circuit board of the disinfection cabinet can be electrically connected to the inner lamp tube 2 and the trigger wire 3 through the conductive pin 6 and the trigger wire 20, respectively, so as to control the operation of the pulse ultraviolet light-emitting tube. They are all fixedly extended at the outer end of the end seat 5, so they will not affect the overall appearance of the pulse ultraviolet light-emitting tube, ensuring its overall appearance. At the same time, it also avoids the problem of opening a hole in the side wall of the outer lamp tube 1, which makes its processing and production difficult and costly, so as to facilitate the processing and production of the outer lamp tube 1 and reduce the production cost.

[0043] In this embodiment, the end seat 5 is a ceramic seat, the outer lamp tube 1 covers the middle position of the inner lamp tube 2 and the trigger wire 3, and the two ends of the inner lamp tube 2 and the trigger wire 3 are respectively located in the open cavity 13, that is, the end seat 5 uses the open cavity 13 to cover the two ends of the inner lamp tube 2 and the trigger wire 3. While ensuring that the pulse energy generated by the inner lamp tube 2 and the trigger wire 3 can be transmitted through the outer lamp tube 1, the assembly stability of the inner lamp tube 2 and the trigger wire 3 can be effectively improved, and the problem of loosening of the inner lamp tube 2 and the trigger wire 3 during transportation or use can be avoided. In addition, the end seat 5 can also block the positioning part 10, the conductive adapter 7, the power cord 4, and the limiting part 21, thereby avoiding the exposure of the matching position between the conductive pin 6, the conductive adapter 7, the power cord 4, the trigger wire 3, and the trigger wire 20, which not only improves the appearance of the product, but also ensures the assembly stability between the conductive pin 6, the conductive adapter 7, the power cord 4, the trigger wire 3, and the trigger wire 20.

When assembling, the pulse ultraviolet light-emitting tube is electrically connected to the anode and cathode of the conductive seat through the conductive pins 6, so that the circuit board of the disinfection cabinet can control the operation of the pulse ultraviolet light-emitting tube.
