[0025] Reference Figure 1-4 The embodiment of the present invention is a spark machine with an efficient cooling function, comprising: a machine platform 1, a driving assembly 26 and a blowing assembly 27. A fixed cylinder 2 is provided inside the machine platform 1, and a filter frame 3 is movably connected to the inner surface of the fixed cylinder 2. The filter frame 3 filters impurities generated when the spark machine is running. A connecting plate 4 is fixedly connected to the upper surface of the filter frame 3, and an inserting block 5 is fixedly connected to the right surface of the connecting plate 4. A limiting block 6 is fixedly connected to the upper surface of the machine platform 1, and an inserting slot 7 is provided inside the limiting block 6. By inserting the inserting block 5 into the inserting slot 7 and inserting the filter frame 3 into the fixed cylinder 2 at the same time, the filter frame 3 is placed. The driving assembly 26 comprises a fixing rod 8, a forward and reverse motor 9, The first rotating shaft 10 is fixedly connected to the limit plate 11, and the upper surface of the fixed rod 8 is fixedly connected to the forward and reverse motor 9. The output end of the forward and reverse motor 9 is fixedly connected to the first rotating shaft 10. The side surface of the first rotating shaft 10 is rotatably connected to the fixed rod 8. The side surface of the first rotating shaft 10 is fixedly connected to the limit plate 11. The lower surface of the limit plate 11 is slidably connected to the insert block 5. By starting the forward and reverse motor 9 to drive the first rotating shaft 10 and the limit plate 11 to rotate, the lower surface of the limit plate 11 no longer contacts the insert block 5, and the limit plate 11 no longer limits the insert block 5. The insert block 5 can be taken out from the insertion slot 7, and then the filter frame 3, the connecting plate 4, and the insert block 5 can be taken out to clean the impurities in the filter frame 3.

[0026] The bottom inner wall of the cavity 12 is fixedly connected to a cooling box 19, the cooling box 19 (existing technology, application number CN202120319346.3), the upper surface of the cooling box 19 is fixedly connected to a temperature sensor 25, the interior of the machine 1 is provided with a cavity 12, and the temperature in the cavity 12 can be measured by the temperature sensor 25, the blowing assembly 27 includes a support plate 13, a small drive motor 14, a second shaft 15 and a cooling fan 16, the rear inner wall of the cavity 12 is fixedly connected to the support plate 13, and the support plate 1 3 is fixedly connected to the small drive motor 14, the output end of the small drive motor 14 is fixedly connected to the second rotating shaft 15, the right surface of the second rotating shaft 15 is fixedly connected to the cooling fan 16, and the side surface of the second rotating shaft 15 is rotatably connected to the support plate 13. A heat dissipation groove 17 is provided inside the machine 1. By starting the small drive motor 14 to drive the second rotating shaft 15 and the cooling fan 16 to rotate, the heat generated during the operation of the cooling box 19 is discharged through the heat dissipation groove 17, which can effectively reduce the temperature in the cavity 12.

[0027] The right surface of the cooling box 19 is fixedly connected to a drain pipe 18, and the cooling box 19 cools the working fluid inside. The lower surface of the fixed cylinder 2 is fixedly connected to the drain pipe 18, and the left surface of the cooling box 19 is fixedly connected to a connecting pipe 20. The left surface of the connecting pipe 20 is fixedly connected to a circulating pump 21. The forward and reverse motors 9, the small drive motor 14, and the circulating pump 21 are all electrically connected to an external power supply. The left surface of the circulating pump 21 is fixedly connected to a water inlet pipe 22. A collecting tank 23 is provided inside the machine 1, and a spark machine body 24 is fixedly connected to the upper surface of the machine 1. By starting the circulating pump 21, the working fluid in the cooling box 19 enters the collecting tank 23 through the connecting pipe 20 and the water inlet pipe 22. After the working fluid in the collecting tank 23 is filtered through the filter frame 3, it enters the cooling box 19 through the drain pipe 18 for recycling.

[0028] Working principle: When it is necessary to clean the impurities in the filter frame 3, start the forward and reverse motor 9 to drive the first rotating shaft 10 and the limit plate 11 to rotate, so that the limit plate 11 no longer limits the plug 5, and the plug 5 can be taken out from the slot 7, and then the filter frame 3 and the connecting plate 4 can be taken out to clean the impurities in the filter frame 3. After the cleaning is completed, the filter frame 3 is inserted into the fixed cylinder 2, and the plug 5 at one end of the filter frame 3 is inserted into the slot 7. By starting the forward and reverse motor 9 to drive the first rotating shaft 10 and the limit plate 11 to rotate, the lower surface of the limit plate 11 contacts the plug 5, and the limit plate 11 limits the plug 5 to prevent the position of the plug 5 from shifting. During use, the heat generated by the operation of the cooling box 19 is generated by starting the small drive motor 14 drives the second rotating shaft 15 and the cooling fan 16 to rotate, and the heat generated by the cooling box 19 is discharged through the heat dissipation groove 17, which can effectively reduce the temperature in the cavity 12, so that the cooling box 19 can maintain a suitable operating temperature, thereby ensuring the discharge effect of the working fluid in the cooling box 19. This structure can easily remove the filter frame 3, and can clean the impurities filtered in the filter frame 3, so that the filter frame 3 maintains a good filtering effect, and can enhance the air flow in the cavity 12, and dissipate the heat generated by the cooling box 19 in time, so that the cooling box 19 maintains a suitable operating temperature. The cooling box 19 can operate efficiently, thereby ensuring the discharge effect of the working fluid, reducing discharge abnormalities caused by excessive temperature, and thus improving processing accuracy.
