When the laser processing equipment is working, the temperature of the equipment itself will also rise, and excessive temperature will cause damage to the equipment.

[0013] The beneficial effects of the present invention are: The present invention uses a cooling mechanism and a first injection mechanism to cool the water inside the chamber through a refrigerator when cooling the laser processing equipment. During this period, the pump is started, and the pump will pump cooling water into the inside of the coil. The cooling water will flow inside the coil, so that the laser processing table is cooled by the cooling water. The cooling water will be discharged through the drain pipe. At this time, the water inside the drain pipe will be transported to the inside of the connecting pipe through the conduit, and the water will be transported to the inside of the pipe body through the connecting pipe.

The present invention provides a first injection mechanism, a compression mechanism and a second injection mechanism. When water is sprayed to the bottom of the coil through the first nozzle, the blades will drive the rotating rod to rotate under the impact of the water flow. At this time, the half gear will rotate synchronously with the rotation of the rotating rod. When the half gear is engaged with the rack during rotation, the rack will drive the pressure plate to move downward under the action of the engagement. When the engagement between the half gear and the rack disappears, the rack will be reset under the action of the spring, and the pressure plate will squeeze the airbag when moving downward. At this time, the air pressure inside the airbag will increase, and the gas inside the airbag will be transported to the inside of the air pipe through the hose under the action of the air pressure. At this time, the air pressure inside the delivery pipe will increase, and the water flow will be sprayed out through the second nozzle under the action of the air pressure and act on the surface of the coil, so as to further cool the surface of the coil, thereby facilitating the slowing down of the dissipation speed of the cold air of the cooling water, so as to improve the cooling effect of the device on the laser processing equipment and prevent the cooling of the laser processing equipment from being affected by the dissipation of the cold air of the cooling water.
