[0028] like Figure 2 , Figure 4 As shown, a water inlet 22 is fixedly connected to the front portion of the top of the water tank 21 , and a filter screen 23 is fixedly connected to the top of the inner cavity of the water tank 21 .

[0029] Water is added into the water tank 21 through the water inlet 22, and the water is filtered by the filter screen 23 to filter out impurities in the water, thereby preventing the subsequent cooling water pipe 27 from being blocked, thereby achieving the effect of preventing blockage.

[0030] like Figure 1 , Figure 2 As shown, a water pump 24 is fixedly connected to the bottom end of the water tank 21, and water pipes 25 are fixedly connected to the output ends on both the left and right ends of the water pump 24. A valve 26 is fixedly connected to the outer wall of the water pipe 25. The outer wall of the water pipe 25 on the right side is fixedly connected to the outer wall of the collecting tank 11, and the outer wall of the water pipe 25 on the left side is fixedly connected to the bottom of the right end of the laser engraving body 12.

[0031] When the water in the water tank 21 needs to be replaced, the water pump 24 is started, the valve 26 located on the outer wall of the right water pipe 25 is opened, and the valve located on the outer wall of the left water pipe 25 is closed at the same time, so that the water in the water tank 21 can be discharged into the collection tank 11 for centralized treatment.

[0032] like Figure 2 , Figure 3As shown, a cooling water pipe 27 is fixedly connected to the rear portion of the top end of the water tank 21, the top of the cooling water pipe 27 is fixedly connected to the inner wall of the connecting block 13, the outer wall of the cooling water pipe 27 is fixedly connected to the right portion of the inner cavity of the laser engraving body 12, the bottom of the cooling water pipe 27 is fixedly connected to the left end of the water pipe 25 on the left side, a support plate 28 is fixedly connected to the top of the front end of the water tank 21, an air conditioner 29 is fixedly connected to the top of the support plate 28, a connecting pipe is fixedly connected to the output end of the air conditioner 29, and the outer wall of the connecting pipe is fixedly connected to the top of the front end of the water tank 21.

[0033] Cold air is blown into the water tank 21 by the air conditioner 29 , and then the cooling water in the water tank 21 is pumped out by the water pump 24 and discharged into the cooling water pipe 27 , so that the cooling water flows in the cooling water pipe 27 .

[0034] like Figure 4 , Figure 5 As shown, the output end of the motor 31 is fixedly connected to a rotating rod 32, the outer wall of the rotating rod 32 is fixedly connected to a sleeve block 33 in a linear array, the outer wall of the sleeve block 33 is fixedly connected to three mounting blocks 34 in a circular array, and the inner cavity of the mounting block 34 is rotatably connected to a stirring rod 35.

[0035] By starting the motor 31, the motor 31 drives the rotating rod 32 to rotate, and the rotating rod 32 drives the stirring rod 35 to rotate, so that the stirring rod 35 stirs the water, so that the water can better contact the water-cooled air, and the cooling speed of the water is accelerated, so as to facilitate cooling of the laser engraving machine and achieve the effect of accelerating water cooling.

[0036] like Figure 2 , Figure 3 As shown, the output end of the second motor 41 is fixedly connected to a rotating disk 42, and the outer wall of the rotating disk 42 is fixedly connected to four fan blades 43 in a circular array.

[0037] The second motor 41 is started, and the turntable 42 is driven by the second motor 41 to rotate, and the turntable 42 drives the fan blades 43 to rotate synchronously, so that the cold air emitted by the cooling water pipe 27 is blown to the working laser engraving machine to dissipate the heat of the laser engraving machine, thereby achieving a heat dissipation effect.

[0038] The working principle of the utility model is as follows: when the laser engraving machine on the laser engraving main body 12 is working, the water pump 24 is started to draw out the cooling water in the water tank 21 and discharge it into the cooling water pipe 27. The cooling water flows in the cooling water pipe 27 and finally returns to the water tank 21. At the same time, the motor 2 41 is started while the water pump 24 is started. The motor 2 41 drives the turntable 42 to rotate. The turntable 42 drives the fan blades 43 to rotate synchronously. The cold air emitted by the cooling water pipe 27 is blown to the working laser engraving machine to dissipate the heat of the laser engraving machine, which has a heat dissipation effect. When cooling, the air conditioner 29 and the motor 1 31 are started at the same time. The cold air produced by the air conditioner 29 is blown into the water tank 21 to cool the water in the water tank 21. At the same time, the motor 1 31 drives the rotating rod 3 2 rotates, the rotating rod 32 drives the stirring rod 35 to rotate, so that the stirring rod 35 stirs the water, so that the water can better contact the water-cooled air, and the cooling speed of the water is accelerated, so as to facilitate cooling and cooling the laser engraving machine, and play a role in accelerating water cooling. Later, when the water level in the water tank 21 is too low, water is added to the water tank 21 through the water inlet 22, and the water is filtered by the filter 23 to filter impurities in the water to prevent the subsequent cooling water pipe 27 from being blocked, which has the effect of preventing blockage. When the water in the water tank 21 needs to be replaced, the water pump 24 is started, the valve 26 located on the outer wall of the right water pipe 25 is opened, and the valve located on the outer wall of the left water pipe 25 is closed at the same time, so that the water in the water tank 21 can be discharged into the collecting tank 11, which is convenient for centralized treatment, thereby improving the user experience.
