A use method of a compressor accessory filter element convenient for changing a filter area specifically comprises the following steps:

the first step is as follows: when in use, a user respectively sleeves the second fixed shells at the upper end and the lower end at the outer side end positions of the first fixed shells at the upper end and the lower end, then rotates the extrusion ring to enable the special-shaped block to move and extrude the connecting rod to move until the connecting rod moves to the inner position of the third limiting groove, simultaneously the limiting ring extrudes the third spring to a compressed state until the upper end position of the connecting rod is clamped at the inner position of the arc-shaped groove, so that the position between the first fixed shells at the upper end and the lower end and the second fixed shells at the upper end and the lower end are fixed, the connecting rod can be separated from the arc-shaped groove by forcibly and reversely rotating the extrusion ring again, the disassembly of the filter screen is convenient, when the filter screen is replaced, the mechanism between the first fixed shells at the upper end and the lower end can be ensured to be repeatedly utilized, thereby saving resources, and the whole filter element is formed, when the device is used, the position of the filter element penetrates into the inner position of the pipeline main body, the elastic belt is extruded to a compression state when the filter element moves downwards, and the elastic belt can be reset to pop out the filter element when the filter element is subsequently taken out, so that the filter element is convenient to take out;

the second step is that: when the filter element is arranged at the inner position of the pipeline main body, the horizontal rod extrudes the fixture block to be recovered to the inner position of the cavity, and extrudes and compresses the second spring, until the second limit groove is aligned with the fixture block, the second spring drives the fixture block to reset and be clamped at the inner position of the second limit groove, then a user rotates the movable rod to enable the movable rod to enter the inner position of the convex block, then the extrusion block is extruded to enable the fixture block to further go deep into the inner position of the second limit groove, the second spring is in a stretching state, meanwhile, the rotary block moves to the inner position of the arrangement groove to enable the filter element to be completely fixed, thereby preventing the outer surface of the filter screen from attaching to the inner surface position of the pipeline main body, preventing the contact position from failing to play a filtering role, and when the movable rod moves downwards, the first fixing shell at the upper end is driven, the gap space between the folds is increased, the filtering area is increased, and the situation that sundries are accumulated in the fold gaps when the filter is used for a long time, so that the gas circulation is not smooth and the filtering efficiency is reduced is prevented;

the third step: then pull the operating block outward, make the gag lever post move to the left side, and make the first spring be stretched, then place the apron in the position of main body of the pipeline, the activity of extension piece passes the space that the fixed ring forms with the main body of the pipeline outside at the same time, then loosen the operating block, make the first spring drive the gag lever post and reset the joint in the first spacing inslot position, thus make the apron fix in the position of main body of the pipeline, the installation of the whole apparatus is finished and can be used, pull the gag lever post to break away from the first spacing inslot portion again while dismantling can, facilitate the apron to break away from, thus facilitate the change installation work of the filter core;

the fourth step: when the device uses, gas after the filtration is discharged through the horizontal pipe, it is normal to discharge the wind speed when the filter core uses normally, make the fly leaf rotate the slope to the right side under the air current effect, first contact and second contact separation, when the filter core is blockked up, make and reduce through the air current, thereby make the inside air current dynamics of horizontal pipe reduce, the fly leaf resets to the vertical position under the action of gravity, thereby make first contact and second contact, make bee calling organ and warning light intercommunication battery, thereby make bee calling organ report to the police, warning light is lighted simultaneously and is carried out the work of warning, the suggestion user needs to carry out the renewal work to the filter core, when preventing that the filter core from changing according to installation time, the filter core does not use the waste that leads to the fact completely.

Compared with the prior art, the invention has the beneficial effects that:

1. the filter core is completely fixed by rotating the movable rod to enable the movable rod to enter the inner position of the protruding block and then extruding the extrusion block to enable the fixture block to further penetrate into the inner position of the second limiting groove, the second spring is in a stretching state, and meanwhile, the rotating block moves to the inner position of the arranging groove, so that the outer surface of the filter screen is prevented from being attached to the inner surface of the pipeline main body, and the contact position cannot play a role in filtering;

2. when the movable rod moves downwards, the first fixed shell at the upper end is driven to move downwards, so that the elastic rod bends outwards, the position of the inner side end of the filter screen is extruded, the filter screen is completely unfolded, the gap space between folds is increased, the filtering area is increased, sundries are prevented from accumulating in the gaps of the folds when the filter screen is used for a long time, the gas circulation is not smooth, and the filtering efficiency is reduced;

3. when the filter element is blocked, the air flow is reduced, so that the air flow strength in the horizontal pipe is reduced, the movable plate is reset to the vertical position under the action of gravity, the first contact is contacted with the second contact, the buzzer and the warning lamp are communicated with the storage battery, the buzzer alarms, and the warning lamp is lightened to warn, so that a user is prompted to replace the filter element, and the waste caused by the fact that the filter element is not completely used when the filter element is replaced according to the installation time is prevented.
