[0029] The fan motor 2 is arranged at the bottom of the DC fan 301, and the switching power supply 202 is arranged at the bottom of the DC fan 301.

[0030] It should be further explained that when the main housing 1 is in use, the parts to be cleaned need to be first placed inside the main housing 1, and then the filtering mechanism 3 sucks in the tiny dust by means of vacuum pumping. After filtering the dust, the clean gas is discharged into the atmosphere to avoid the tiny dust affecting the function and service life of the components.

[0031] Please refer to Figures 2-6 , the present utility model provides the following technical solutions:

[0032] Filtering mechanism 3, the filtering mechanism 3 includes a DC fan 301, a primary filter 302, a high-efficiency filter 303, a dust suction port cavity 304, a dust suction port cavity 305, a one-two cavity communication channel 306, a differential pressure switch 307 and a filter element replacement alarm 308. The DC fan 301 is arranged inside the main housing 1, the primary filter 302 is arranged on the top of the main housing 1, the high-efficiency filter 303 is arranged at the bottom of the primary filter 302, the dust suction port cavity 304 is arranged on the top of the primary filter 302, the dust suction port cavity 305 is arranged at the bottom of the high-efficiency filter 303, the one-two cavity communication channel 306 is arranged on one side of the main housing 1, the differential pressure switch 307 is arranged at the bottom of the DC fan 301, and the filter element replacement alarm 308 is arranged on one side of the main housing 1.

[0033] The DC fan 301 is arranged at the bottom of the upper cover body 101, and the primary filter 302 is arranged inside the upper cover body 101.

[0035] The one-two cavity communication channel 306 is arranged on one side of the upper cover body 101 and on one side of the DC fan 301.

[0036] It should be further explained that: First, the DC fan 301 operates to generate a vacuum. Dust enters the interior of the main housing 1 from the dust suction port body 104. The primary filter 302 filters out relatively large particles of dust, and the high-efficiency filter 303 filters out fine dust. Then, the clean gas passes through the DC fan 301 and enters the atmosphere through the exhaust window 206. The dust suction port chamber 304 and the first and second chamber communication channel 306 are connected through the first and second chamber communication channel 306 and then connected to the differential pressure switch 307. When there is a lot of dust, the differential pressure of the first and second chamber communication channel 306 reaches the set value, and the filter element replacement alarm 308 is activated to prompt the replacement of the filter element. To replace the filter element, just open the buckle 103 and move the upper cover body 101 away through the upper cover handle 102 to replace the primary filter 302 and the high-efficiency filter 303.

[0037] Working principle: When a fine dust collection system is in use, first, when the main housing 1 is in use, the parts to be cleaned need to be placed inside the main housing 1 first. Then, the filtering mechanism 3 sucks in the fine dust by means of vacuum pumping, filters the dust, and discharges the clean gas into the atmosphere to prevent the fine dust from affecting the function and lifespan of the components.

[0038] When it is necessary to remove the fine dust on the surface of the parts, first, the DC fan 301 operates to generate a vacuum. Dust enters the interior of the main housing 1 from the dust suction port body 104. The primary filter 302 filters out relatively large particles of dust, and the high-efficiency filter 303 filters out fine dust. Then, the clean gas passes through the DC fan 301 and enters the atmosphere through the exhaust window 206. The dust suction port chamber 304 and the first and second chamber communication channel 306 are connected through the first and second chamber communication channel 306 and then connected to the differential pressure switch 307. When there is a lot of dust, the differential pressure of the first and second chamber communication channel 306 reaches the set value, and the filter element replacement alarm 308 is activated to prompt the replacement of the filter element. To replace the filter element, just open the buckle 103 and move the upper cover body 101 away through the upper cover handle 102 to replace the primary filter 302 and the high-efficiency filter 303. This device is convenient for removing the fine dust on the surface of the parts.
