[0027] The utility model is further described below in conjunction with the accompanying drawings and embodiments. Embodiment 1:

[0029] In this embodiment, the trigger wire 3 is wound around the inner tube 2 located inside the outer tube 1, and at the same time, the power line 4 is electrically connected to both ends of the inner tube 2, and one end of the trigger wire 3 is electrically connected to the trigger wire 20, so that the circuit board of the disinfection cabinet can be electrically connected to the inner tube 2 and the trigger wire 3 through the power line 4 and the trigger line 20, respectively, so as to control the operation of the pulse ultraviolet strong light tube. Since the power line 4 and the trigger line 20 are extended toward the outer end of the outer tube 1, the overall appearance of the pulse ultraviolet strong light tube will not be affected, so as to ensure the integrity of its appearance, and at the same time, it is also avoided that a hole needs to be opened in the side wall of the outer tube 1, which leads to the problem of difficulty in its processing and production and high cost, so as to facilitate the processing and production of the outer tube 1 and reduce the production cost, and the power line 4 and the trigger line 20 extended at the end can be led at any angle and position, so that the pulse ultraviolet strong light tube can be assembled at any position of the disinfection cabinet at any angle, so as to improve the assembly convenience of the pulse ultraviolet strong light tube.

[0030] In order to facilitate the insertion of the power line 4 and the trigger line 20, outer tube wire holes 6 are respectively provided at both ends of the outer tube 1, and fixed wire holes 7 are respectively provided on the fixing parts 5 at both ends. The power lines 4 at both ends and the trigger line 20 at one end extend toward the outer end of the outer tube 1 through the outer tube wire holes 6 and the fixed wire holes 7 in turn. That is, the power line 4 and the trigger line 20 at one end extend toward the outer end of the outer tube 1 through the common outer tube wire holes 6 and the fixed wire holes 7 at one end in turn, and the power line 4 at the other end extends toward the outer end of the outer tube 1 through the common outer tube wire holes 6 and the fixed wire holes 7 at the other end.

[0031] In addition, a trigger wire passing hole is provided on one end of the fixing member 5, and the trigger wire passing hole and the fixed wire passing hole 7 are separately provided. The trigger wire 20 at one end passes through the outer tube wire passing hole 6 and the trigger wire passing hole in sequence and extends toward the outer end of the outer tube 1, that is, the power line 4 and the trigger line 20 extend toward the outer end of the outer tube 1 through different wire passing holes on the fixing member 5 respectively.

[0032] In this embodiment, the power line 4 and the trigger line 20 preferably extend toward the outer end of the outer tube 1 through a common fixed wire hole 7 at one end.

[0033] The fixing member 5 is fixed on the outer tube 1 by clamping, sleeve setting or fasteners.

[0034] Specifically, the outer tube 1 completely covers the inner tube 2 and the trigger wire 3 , and outer tube clamping parts 8 are respectively extended from both ends of the outer tube 1 . The fixing member 5 is provided with a fixing clamping part 9 , which is fixedly clamped on the outer tube clamping part 8 through the fixing clamping part 9 .

[0035] The fixing member 5 of this embodiment is fixed on the outer tube 1 by a clamping method, and its structure is simple and reasonable, the assembly is convenient, and the production cost is low.

[0036] Furthermore, the outer tube clamping portion 8 is in the form of a sheet, the fixed clamping portion 9 is an open groove, and the clamping fixed card is arranged on the outer tube clamping portion 8, thereby further improving the convenience of assembly between the fixing member 5 and the outer tube 1.

[0037] The outer tube wire hole 6 of this embodiment is arranged on the outer tube clamping portion 8. After the fixing member 5 is assembled, its fixed wire hole 7 and the outer tube wire hole 6 are on the same axis, so that the power line 4 and the trigger line 20 extend linearly to avoid bending of the power line 4 and the trigger line 20.

[0038] The outer tube 1 and the inner tube 2 are made of quartz glass, and a spacer cavity 13 is formed between the two. The trigger wire 3 is located in the spacer cavity 13 and rotates around the outer periphery of the inner tube 2. Since the outer tube 1 and the inner tube 2 are both made of quartz glass, it is beneficial to the transmission of pulsed ultraviolet rays, and at the same time has high strength and long service life.

[0039] In this embodiment, the inner tube 2 and the trigger wire 3 are completely covered by the outer tube 1, which not only effectively protects the inner tube 2 and the trigger wire 3, but also reduces the obstruction of the inner tube 2 and the trigger wire 3, so that the pulsed ultraviolet energy generated by the inner tube 2 and the trigger wire 3 can be fully transmitted through the outer tube 1.

[0040] The outer tube 1 and the inner tube 2 are straight tubes, U-shaped tubes, round tubes, S-shaped tubes, or any combination of the above shapes. The outer tube 1 and the inner tube 2 of this embodiment are straight tubes as an example, and both are straight cylindrical.

[0041] The inner tube 2 is also filled with an inert gas, such as xenon, argon, krypton, etc. The power lines 4 at both ends are respectively an anode and a cathode, and extend into the inner tube 2 respectively. One end of the trigger wire 3 is electrically connected to a trigger wire 20.

[0042] When the pulsed ultraviolet light tube is working, the inner tube 2 can generate pulsed strong light with a wavelength of 210-1200nm. The pulsed strong light passes through the outer tube 1 to disinfect the inside of the disinfection cabinet, and the disinfection efficiency is high and the effect is good. Embodiment 2:

[0043] See also Figure 5-Figure 8 The pulsed ultraviolet light tube for the disinfection cabinet is different from the first embodiment in that the outer tube 1 is a straight cylindrical shape with holes through the front and back, and covers at least part of the inner tube 2 and the trigger wire 3, and the fixing member 5 is provided with an annular sleeve portion 10, and is fixedly sleeved on the outer tube 1 through the annular sleeve portion 10.

[0044] Specifically, the outer tube 1 is a cylindrical shape with equal diameter and hollow front and back, so outer tube wire holes 6 are formed at both ends, and the fixing member 5 is fixed to the outer tube 1 by sleeve connection. It has a simple and reasonable structure, is easy to assemble, and has low production cost.

[0045] The fixing member 5 is provided with an open cavity 11 , and the annular sleeve portion 10 is located outside the open cavity 11 . The fixing member 5 covers the inner tube 2 and the rest of the trigger wire 3 through the open cavity 11 .

[0046] In this embodiment, the fixing member 5 is a ceramic seat, the middle parts of the inner tube 2 and the trigger wire 3 are located in the outer tube 1, and the two ends are respectively located in the open cavity 11. The fixing member 5 uses the open cavity 11 to cover the two ends of the inner tube 2 and the trigger wire 3. While ensuring that the pulse energy generated by the inner tube 2 and the trigger wire 3 can be transmitted through the outer tube 1, the assembly stability of the inner tube 2 and the trigger wire 3 can be effectively improved, and the problem of the inner tube 2 and the trigger wire 3 loosening during transportation or use can be avoided.

[0047] A limiting member 12 is further provided between the power line 4 and / or the trigger line 20 and the inner tube 2 , and the limiting member 12 is limited and matched, and the limiting member 12 is located in the opening cavity 11 .

[0048] In this embodiment, a limiting member 12 is provided between the power cord 4, the trigger wire 20 and the inner tube 2. The setting of the limiting member 12 can not only ensure the assembly stability between the power cord 4, the trigger wire 20 and the inner tube 2, and prevent the power cord 4 and the trigger wire 20 from loosening, but also the limiting member 12 can cooperate with the inner wall of the opening cavity 11 to further improve the assembly stability of the inner tube 2 and the trigger wire 3.

[0049] The power cord 4 and the trigger cord 20 are also provided with positioning parts 14, respectively. The positioning parts 14 are located between the fixed wire hole 7 and the limiting member 12 to limit the front and rear positions of the power cord 4 and the trigger cord 20, thereby effectively avoiding the loosening problem of the power cord 4 and the trigger cord 20, and ensuring that the power cord 4 and the trigger cord 20 can be electrically connected to the inner tube 2 and the trigger wire 3, respectively.
