Description

Laser tube with bent water tube structure Technical Field The invention relates to the field of laser tubes, in particular to a laser tube with a bent water tube structure. Background The glass tube is directly communicated between the water sleeve and the water nozzle outside the gas storage tube, elasticity is not available, the temperature of cooling water in the water sleeve can rise to between 6 and 20 ℃ in the working process of the laser tube, the temperature change can enable the water sleeve to be long due to expansion caused by heat and contraction caused by cold, the temperature of the gas storage tube outside the laser tube is unchanged, the length of the gas storage tube is unchanged, the position of the water nozzle is unchanged, and stress caused by the difference of the length of the water sleeve and the gas storage tube can lead to burst of a straight-through tube between the water sleeve and the gas storage tube, so that the whole laser tube is damaged. The Chinese patent with the application number 200810007630-6 discloses a spiral water pipe structure laser pipe, which well solves the problem of glass bursting caused by the expansion and contraction change of a water jacket pipe, but generates a new problem, and the expansion length of the spiral water pipe is much longer than the length of the traditional direct connection because of the characteristic of the spiral structure, so that the spiral water pipe or the connection part thereof is easily broken and broken due to vibration during transportation. Disclosure of Invention The present invention has been made in view of the above problems, and it is an object of the present invention to overcome or at least partially solve the above problems. According to one aspect of the invention, a laser tube with a bent water tube structure is provided, the laser tube comprises a discharge tube, a water sleeve is sleeved outside the discharge tube, the water sleeve and the discharge tube are both arranged in a gas storage tube, a protruding column is arranged at the top of the left end of the gas storage tube, a bent water tube is arranged at the left end of the water sleeve, and a water outlet nozzle at the tail end of the bent water tube protrudes out of the protruding column from the inside to the outside. Preferably, the right end of the discharge tube passes through the right port of the water sleeve and the right port of the gas storage tube, and the bottom of the right end of the water sleeve is provided with a water inlet nozzle which passes through the gas storage tube. Preferably, the top of the right end of the water jacket pipe is also extended with a connecting pipe, and the tail end of the connecting pipe is fixed on the inner wall of the gas storage pipe. Preferably, a positive electrode is arranged on the inner side of the right end of the discharge tube, and a total reflection mirror is arranged on the outer side of the right end of the discharge tube. Preferably, the left end of the discharge tube extends out of the water sleeve, the left end of the discharge tube is provided with a negative electrode, the left port of the gas storage tube is provided with an output mirror, and the negative electrode is in conductive connection with the output mirror. Preferably, the output mirror is provided with a first electrode lead, and the total reflection mirror is provided with a second electrode lead. Preferably, the right end of the discharge tube is also communicated with an air return tube, the air return tube adopts a spiral structure, and the air return tube is sleeved outside the water jacket tube. Preferably, the bent water pipe adopts an N-shaped structure, the left lower end of the bent water pipe is communicated with the left end of the water sleeve, the right upper end of the bent water pipe penetrates through the protruding column to be connected with the water outlet nozzle, the left upper end of the bent water pipe is in clearance contact with the inner wall of the gas storage pipe, and the right lower end of the bent water pipe is in contact with the water sleeve pipe. In addition, the unfolding length of the bending water pipe is smaller than that of the spiral water pipe in the transportation process, so that the laser pipe with the bending water pipe structure is not easy to break relative to the laser pipe with the spiral water pipe structure in the transportation vibration process, and the laser pipe is reliable and stable in use and is not easy to break in transportation.
