As shown in Figures 1 to 4, the filter-type oil-free intelligent air compressor of this embodiment includes a shell 1, a side wall of the shell 1 is provided with an air inlet 12, the outer wall of the air inlet 12 is engaged with a card frame 6, the inner side of the card frame 6 is movably engaged with a filter screen 7, a sliding cover 5 is provided on the outside of the card frame 6, the bottom of the outer walls on both sides of the sliding cover 5 are movably threaded with fastening bolts 8, a side wall of the sliding cover 5 close to the filter screen 7 is fixedly connected with a patch 10, the bottom of the sliding cover 5 is fixedly connected with a shovel bar 11, the top of the shell 1 is fixedly connected with a top box 2, the top of the top box 2 is embedded with a transparent plate 3, the outer wall of the top box 2 is provided with an air hole 4, the interior of the top box 2 is provided with a silica gel desiccant 14, the inside of the shell 1 is fixedly installed with an air compressor body 13, and the top of the air compressor body 13 is installed with an air intake pipe 16.

Specifically, the shell 1 is the shell 1 structure of the air compressor, which can protect the intelligent control electrical components inside except the main structure of the air compressor, making the appearance of the oil-free intelligent air compressor more beautiful and unified. The air inlet 12 mainly enters the outside air, so that the air inlet pipe 16 on the internal air compressor body 13 can smoothly inhale air. The card frame 6 can make the filter 7 cover the air inlet 12 of the shell 1, so that the filter 7 can filter and purify the air entering the shell 1. The filter 7 is an air filter 7, which can effectively filter the suspended particles in the air, thereby reducing the air The suspended particles in the housing 1 enter the housing 1 and cause adverse effects on other electrical components in the housing 1. When the sliding cover 5 slides from top to bottom, it can drive the shovel bar 11 to scrape the surface of the filter 7 to clean the filter 7. At the same time, it can also change the size of the air inlet 12, which is more conducive to controlling the air intake volume. When it is completely overlapped with the card frame 6, the air inlet 12 at the housing 1 can be closed, so that the interior of the housing 1 is in a relatively closed state, which is more conducive to the storage of the oil-free intelligent air compressor when not in use. The end of the fastening bolt 8 is fixedly connected with a rubber pad, which can make the sliding cover 5 close after tightening. The bottom end of the cover 5 is fixed to the slide groove 9 of the outer wall of the card frame 6, so that the position of the slide cover 5 on the card frame 6 can be flexibly adjusted. The patch 10 is made of rubber material. When the slide cover 5 and the card frame 6 overlap, they can fit the surface of the filter screen 7 to reduce the gap between the slide cover 5 and the filter screen 7, thereby reducing the probability of suspended particles in the outside air passing through the gap and adhering to the filter screen 7 when the air compressor is stored, which is more conducive to the storage of the air compressor. The shovel strip 11 has a triangular structure, and the bottom end fits with the surface of the filter screen 7, so that when the slide cover 5 slides down, it can fit the surface of the filter screen 7 and slide, thereby achieving The surface of the filter screen 7 can be simply cleaned after a single use. The top box 2 can keep the internal sponge sheet 15 and the silica gel desiccant 14 connected to the outer shell 1. The silica gel desiccant 14 is made of a color-changing silica gel material. The transparent plate 3 is convenient for the user to observe the color change of the silica gel desiccant 14 inside the top box 2, so that the user can know in time whether the surrounding environment is in a humid state, avoiding the use of the air compressor in a humid environment for a long time. The air hole 4 allows the air in the environment around the air compressor to smoothly enter the top box 2, which is beneficial for the silica gel desiccant 14 to absorb moisture in the air and change color.

Furthermore, a sponge sheet 15 is placed at the bottom of the inner side of the top box 2, and a silica gel desiccant 14 is placed on the top of the sponge sheet 15. The silica gel desiccant 14 is movably embedded and connected to the top box 2 through the sponge sheet 15. The function of the sponge sheet 15 is to absorb and lock the water droplets generated on the surface of the silica gel desiccant 14 after absorbing water, so as to prevent the water generated in the top box 2 from overflowing through the air hole 4.

Furthermore, both sides of the outer wall of the card frame 6 are provided with sliding grooves 9, and the fastening bolts 8 are movably connected to the sliding grooves 9. The sliding cover 5 is movably connected to the card frame 6 through the fastening bolts 8 and the sliding grooves 9. The fastening bolts 8 can slide up and down along the sliding grooves 9 when not tightened, and can be close to the inner wall of the sliding grooves 9 after tightening, thereby realizing flexible adjustment of the position of the sliding cover 5 on the card frame 6.

Furthermore, the patch 10 is connected to the movable cover of the filter 7 through the sliding cover 5. The fit between the patch 10 and the filter 7 can protect the filter 7, so that when the air compressor is not in use, the outside air is not easily adsorbed on the filter 7, thereby reducing the frequency of cleaning the filter 7.

Furthermore, the transparent plate 3 is located directly above the silica gel desiccant 14 , and a cavity is opened inside the top box 2 , which helps the air flow in the top box 2 , so that the moisture in the air can stay and condense on the inner wall of the top box 2 , thereby being absorbed by the silica gel desiccant 14 .

Furthermore, the air intake pipe 16 is located on one side of the air inlet 12, and the filter 7 is connected to the movable cover of the air inlet 12 through the card frame 6. The filter 7 can filter the air entering the shell 1 first to reduce the number of suspended particles inside the shell 1, which also helps to extend the service life of the air compressor.

Furthermore, the shovel bar 11 is movably connected to the filter 7 through the sliding cover 5. The surface of the shovel bar 11 has burrs. When sliding against the filter 7, it can extend into the mesh of the filter 7, so that the particles clogging the filter 7 can be scraped off, thereby cleaning the filter 7.

The method of using this embodiment is as follows: when using this filter-type oil-free intelligent air compressor, it is necessary to first connect the air compressor to an external power supply, and then the internal air compressor body 13 starts to inhale air through the air inlet pipe 16, so that negative pressure is generated inside the shell 1, so that the air outside the shell 1 enters the shell 1 through the air inlet 12, and when the external air passes through the air inlet 12, it will be filtered by the filter 7, so that the suspended particles entrained in the air are adsorbed and filtered, so that the air entering the shell 1 is relatively clean air, and when the air compressor is used in a humid environment, the moisture in the ambient air will enter the top box 2 through the air hole 4 and stay in the cavity of the top box 2, and then the silica gel in the top box 2 will dry. The silica gel desiccant 14 absorbs the moisture in the air, and when the silica gel desiccant 14 absorbs the moisture in the air, it will change from orange to green. At this time, the user can observe the color change of the silica gel desiccant 14 in the top box 2 through the transparent plate 3 to determine whether the use environment of the air compressor is humid, so as to avoid the air compressor being used in a humid environment for a long time. At the same time, after the use of the air compressor is completed, the fastening bolts 8 can be loosened to make the sliding cover 5 slide down along the card frame 6. At this time, the shovel bar 11 at the bottom end of the sliding cover 5 will scrape the surface of the filter screen 7 to simply clean the surface of the filter screen 7. When the sliding cover 5 and the card frame 6 are completely overlapped, the fastening bolts 8 are tightened again to make the patch 10 on the side wall of the sliding cover 5 close to the filter screen 7, and the air inlet 12 will also be closed.

Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
