[0096] Further, the gas source box 124 further comprises a pressure switch 1247 installed in the gas path to test the gas pressure and electrically connected with the air pump controller, when the gas pressure exceeds the preset range, to ensure the safety of the gas path, the pressure switch 1247 controls the air pump 1241 to stop working through the air pump controller to reduce the gas pressure in the gas path, when it is detected that the gas pressure is less than the preset range, the pressure switch 1247 controls the air pump 1241 to start working again through the air pump controller to maintain the stability of the gas pressure in the gas path, ensuring that the gas source assembly 12 can stably and safely deliver gas.

[0097] Preferably, a second safety valve can also be arranged at the rear end of the air pump 1241 in the gas path, to release pressure and reduce pressure when it is detected that the gas pressure output by the air pump 1241 is higher than the preset value, to control the gas pressure in the gas path and enhance the safety of the operation of the gas path, avoiding safety hazards caused by excessively high gas pressure.

[0098] Further, a pressure relief hole 1248 is opened on the box 1246 corresponding to the second safety valve, when the second safety valve releases pressure, the gas flows out from the pressure relief hole 1248 to maintain the balance of the gas pressure inside and outside the box 1246, improving the safety of the operation of the gas source assembly 12.

[0099] Preferably, the gas source assembly 12 comprises a four-way connector, which is connected with the gas pump 1241, the pressure switch 1247, the condenser 1244 and the second safety valve respectively, so that the above-mentioned connected devices are connected with the gas circuit, and the gas pressure in the gas circuit can be quickly adjusted when the gas pressure changes, so as to ensure the stability and safety of the gas source box 124.

[0100] In summary, please combine Figures 1 to 6 , and Figures 8 to 10 , the working process and principle of the first embodiment of the present application are as follows:

[0101] When the gas source system 1 works, the control assembly 11 is detachably connected with the gas source assembly 12 through the corresponding installation position 122, and the control assembly 11 is connected with the second power input interface 125 through the power supply output interface 118 to realize power supply of the control assembly 11 to the gas pump 1241. When the gas pump 1241 works, the compressed gas passes through the condenser 1244, the water and oil removal device 1242 and the filter 1243 in turn, and then the pure and dry gas is transmitted to the control assembly 11 through the connection between the gas input interface 111 and the second gas output interface 123. In the control assembly 11, the electromagnetic valve 113 controls the on-off of the gas, and the gas is output through the first gas output interface 112 under the control of the electromagnetic valve 113.

[0102] Please refer to Figure 1 , Figure 5 and Figure 7 , the second embodiment of the present application provides a laser generating device, which comprises a laser gun head 2, a laser output head 3 and a laser generator 4, and further comprises the gas source system 1 provided in the first embodiment. The laser output head 3 is connected with the laser generator 4 and the laser gun head 2 at two ends respectively, and the gas source system 1 is connected with the laser gun head 2 and transmits gas to the laser gun head 2.

[0103] It can be understood that the laser generator 4 generates laser and transmits the laser to the laser gun head 2 through the laser output head 3, and the gas source system 1 transmits gas to the laser gun head 2. When the laser gun head 2 works for welding or cutting, the gas acts as a protective gas to assist the laser work, thereby improving the welding and cutting quality.

[0104] Further, the laser gun head 2 comprises an electric control wire 21, and the control assembly 11 is provided with an electric input interface 119 which is electrically connected with the electromagnetic valve 113. The electric input interface 119 is electrically connected with the laser gun head 2 through the electric control wire 21.

[0105] It can be understood that the laser gun head 2 transmits an electric signal for controlling gas to the control assembly 11 through the electric control wire 21, so as to realize the control of the gas transmission.

[0107] Alternatively, referring to Figure 5 、 Figures 7 to 9 , the electrical input interface 119 and the first power supply input interface 120, which are respectively responsible for receiving electrical signals and two interfaces responsible for supplying power to the gas source system 1, can be arranged in two interfaces or in the same interface, and users can choose flexibly according to their needs.

[0108] Preferably, the control assembly 11 further comprises a gas pressure sensor 1111, which is electrically connected to the laser generator 4 through the electrical input interface 119, and the gas pressure sensor 1111 is connected to the front end / rear end of the electromagnetic valve 113.

[0109] As can be understood, when the gas is not transmitted into the control assembly 11, the gas pressure sensor 1111 cannot detect the gas pressure in the gas circuit, at which time an electrical signal that does not output laser is transmitted to the laser generator 4, avoiding the damage to the cutting and welding quality caused by the laser gun head 2 outputting laser without protective gas.
