The operator will open or close specific valves according to needs to change the fluid flow direction, thereby realizing the switching between adsorption and backwashing. This method requires the operator to have certain professional knowledge and skills to ensure the accuracy and safety of the switching process. When switching, the vacuum pump needs to be stopped first and then started after switching. Summary of the Utility Model

One side of the switching box 2 is fixedly connected to an exhaust duct 5 and a blowing duct 6, and the other side of the switching box 2 is fixedly connected to a connecting pipe 7, a pressure relief valve 8 and a silencer 9. An exhaust port 10 is opened at the top of the switching box 2. Specifically, the vacuum pump 1 is connected to an external power supply, which refers to a device or equipment that uses mechanical, physical, chemical or physical-chemical methods to evacuate the container to be evacuated to obtain a vacuum. The first adsorption hose 3 and the second adsorption hose 4 have deformable properties. The exhaust duct 5 and the blowing duct 6 are respectively fixedly connected to one ends of the first adsorption hose 3 and the second adsorption hose 4. When the pressure in the air receiver exceeds the pressure relief critical point of the pressure relief valve 8, the piston of the air receiver pressure relief valve 8 will automatically open to achieve the purpose of releasing pressure and play a protective role. The silencer 9 is used to reduce the exhaust noise of the vacuum pump 1; a switching component, which is used to realize the automatic switching function of adsorption and back-blowing, and the switching component is connected to the switching box 2; an adjusting component, which is used to adjust the magnitude of the back-blowing flow rate, and the adjusting component is connected to the switching box 2.

[0021] Please refer to Figures 1-4, the switching component includes a first partition 11 fixedly connected to the inner wall of the switching box 2. The inner wall of the switching box 2 is fixedly connected with a second partition 12. A first through opening 13 is formed on the outer wall of the first partition 11, and a second through opening 14 is formed on the outer wall of the second partition 12. The outer wall of the switching box 2 is fixedly connected with a cylinder 15. One end of the piston rod of the cylinder 15 is fixedly connected with a push rod 16. The push rod 16 penetrates through the switching box 2 and can slide relative to the switching box 2. One end of the push rod 16 is fixedly connected with a rubber washer 17. Specifically, when the rubber washer 17 blocks the second through opening 14 on the second partition 12, the area above the second partition 12 in the switching box 2 is sealed, and the areas on both sides of the first partition 11 are connected. Open the air extraction port on the vacuum pump 1 to start air extraction. The air passes through the first adsorption hose 3 and the air extraction pipe 5, passes through the area below the first partition 11 in the switching box 2, reaches the area between the first partition 11 and the second partition 12, and passes through the connection pipe 7 to extract air from the adsorption area of the machine tool so that the adsorption area reaches a vacuum state. The air discharged from the air blowing port on the vacuum pump 1 passes through the second adsorption hose 4 and the air blowing pipe 6, passes through the area above the second partition 12 in the switching box 2, and is discharged through the air discharge port 10 and the silencer 9. When the rubber washer 17 blocks the first through opening 13 on the first partition 11, the area below the first partition 11 in the switching box 2 is sealed, and the areas on both sides of the second partition 12 are connected. The air discharged from the air blowing port on the vacuum pump 1 passes through the second adsorption hose 4 and the air blowing pipe 6, passes through the area above the second partition 12 in the switching box 2, reaches the area between the first partition 11 and the second partition 12, and blows air through the air discharge port 10, the silencer 9 and the connection pipe 7 to the adsorption area of the machine tool to quickly relieve the pressure. The cylinder 15 is connected to an external power supply. The rubber washer 17 is made of deformable material and can block the first through opening 13 or the second through opening 14. By setting the switching component and connecting the connection pipe 7 to the adsorption area of the machine tool, when the cylinder 15 is in the retracted state, the rubber washer 17 blocks the second through opening 14, making the area above the second partition 12 in the switching box 2 sealed, and the areas on both sides of the first partition 11 connected. When the adsorption area of the machine tool does not need to be in a vacuum state and needs to be quickly depressurized, start the cylinder 15 to drive the rubber washer 17 to move and block the first through opening 13, making the area below the first partition 11 in the switching box 2 sealed, and the areas on both sides of the second partition 12 connected. Thus, the adsorption and reverse blowing automatic switching function can be realized with one structure. The working vacuum pump 1 does not need to be started and stopped frequently, protecting the service life of the vacuum pump 1. And the device has few parts, is convenient to manufacture, simple and convenient to maintain, and has a wide application range.

[0022] Please refer to Figures 5-6, the adjusting assembly includes an adjusting knob 18 rotatably connected to the top of the switching box 2. A fixing plate 19 is fixedly connected to the outer wall of the adjusting knob 18. A sliding groove 20 is formed in the top of the switching box 2. A sliding bolt 21 is fixedly connected to the bottom of the fixing plate 19. The outer wall of the sliding bolt 21 is slidably connected to the inner wall of the sliding groove 20. Specifically, the fixing plate 19 is circular and can completely cover the air outlet 10, and the sliding groove 20 and the sliding bolt 21 will not be separated, so that the fixing plate 19 can rotate around the adjusting knob 18 as the center. By setting the adjusting assembly, rotating the adjusting knob 18 drives the fixing plate 19 to rotate around it as the center. The fixing plate 19 drives the sliding bolt 21 to slide along the inner wall of the sliding groove 20, so that the area of the fixing plate 19 covering the air outlet 10 changes, and thus the air volume can be adjusted according to needs, effectively improving the practicability of the adsorption and back-blowing switching device.

[0023] During use, the operator connects the connecting pipe 7 to the adsorption area of the machine tool. In the retracted state of the air cylinder 15, the rubber washer 17 blocks the second through hole 14 on the second partition plate 12, sealing the area above the second partition plate 12 in the switching box 2, and the areas on both sides of the first partition plate 11 are communicated. The vacuum pump 1 is turned on, and the air suction port on the vacuum pump 1 starts to suck air. The air passes through the first adsorption hose 3 and the air suction pipe 5, reaches the area below the first partition plate 11 in the switching box 2, and then reaches the area between the first partition plate 11 and the second partition plate 12, and then sucks the adsorption area of the machine tool through the connecting pipe 7 to make the adsorption area reach a vacuum state. The air discharged from the air blowing port on the vacuum pump 1 passes through the second adsorption hose 4 and the air blowing pipe 6, passes through the area above the second partition plate 12 in the switching box 2, reaches the air outlet 10 and the silencer 9, and discharges the air. When the adsorption area of the machine tool does not need to be in a vacuum state and needs to be quickly depressurized, the air cylinder 15 is started to drive the push rod 16 to extend. The push rod 16 drives the rubber washer 17 to move so that the rubber washer 17 blocks the first through hole 13 on the first partition plate 11, sealing the area below the first partition plate 11 in the switching box 2, and the areas on both sides of the second partition plate 12 are communicated. The air discharged from the air blowing port on the vacuum pump 1 passes through the second adsorption hose 4 and the air blowing pipe 6, passes through the area above the second partition plate 12 in the switching box 2, reaches the area between the first partition plate 11 and the second partition plate 12, and blows the adsorption area of the machine tool through the air outlet 10, the silencer 9 and the connecting pipe 7 to make the adsorption area reach a quick pressure relief. When it is necessary to adjust the air volume, rotate the adjusting knob 18. The adjusting knob 18 drives the fixing plate 19 to rotate around it as the center. The fixing plate 19 drives the sliding bolt 21 to slide along the inner wall of the sliding groove 20, so that the area of the fixing plate 19 covering the air outlet 10 changes.
