[0026] Furthermore, the side of the outer frame 103 is closely fitted to the inner side of the ventilation hole 7, and the size of the filter 104 is larger than the size of the ventilation hole 7;

[0027] During operation, the side of the outer frame 103 is tightly fitted with the inner side of the ventilation hole 7 , and the size of the filter 104 is larger than that of the ventilation hole 7 , thereby improving the effect of the filter 104 on filtering the air entering the ventilation hole 7 .

[0036] Working principle: When using the combined dustproof box transformer, the outer frame 103 is inserted into the through slot 9 on the rear side of the box shell 1 by sliding, and the outer frame 103 is squeezed by pressing the card block 101 to squeeze the card strip 113. The inclined surface of the card strip 113 is subjected to pressure to make the card strip 113 slide backward on the surface of the mounting block 111 through the slide column 112. When the outer frame 103 slides to the rear of the ventilation hole 7, the spring 114 on the surface of the slide column 112 supports the card strip 113, so that the card strip 113 is engaged in the outer frame 103. At this time, the outer frame 103 is engaged in the through slot 9. The structure is simple and easy to install. At this time, the fan 16 is started by an external power supply, and the fan 16 discharges the air in the device through the through pipe 13. The air pressure in the device is reduced, and the air outside enters through the ventilation hole 7 and is filtered by the filter 104.

[0037] When a large amount of dust accumulates on the surface of the filter component 10 when the device is working for a long time, the box door 4 is opened by the handle 5, and the clamping strip 113 is pulled inward to separate the clamping strip 113 from the surface of the outer frame 103 and slide out of the outer frame 103, so as to facilitate replacement of the cleaning device. The device combines the filter component 10 with the fan 16 and the through pipe 13 to improve the adaptability of the device.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
