[0025] See also Figures 1 to 5 , a cylindrical micro electrostatic filter;

[0026] include:

[0027] An installation top cover 1 is installed, and intercepting rods 2 are rotatably connected to the four sides of the bottom of the installation top cover 1. The bottom end of the intercepting rod 2 is fixedly connected to a mounting base 3. An electrostatic filter element 4 is inserted into the top of the installation top cover 1, and the surface of the electrostatic filter element 4 penetrates and is inserted into the inner wall of the installation base 3. A clockwork spring 5 is fixedly connected to the inner wall of the installation base 3, and a fixed pull rope 6 is fixedly connected to the front end of the clockwork spring 5, and the surface of the fixed pull rope 6 is slidably connected to the inner wall of the installation base 3, and a fixed ring 7 is fixedly connected to the front end of the fixed pull rope 6. A limiting block 8 is fixedly connected to the left side of the installation top cover 1, and a card slot is fixedly connected to the right side of the installation top cover 1, and the horizontal longitudinal section of the limiting block 8 is the same as the horizontal longitudinal section of the card slot, and a connecting plate 9 is fixedly connected to the right side of the installation base 3.

[0028] When installing the electrostatic filter, fit the first group of mounting top covers 1 with the second group of mounting top covers 1, so that the first group of limiting blocks 8 fit in the slots of the second group of mounting top covers 1, and then insert the first group of limiting blocks 8 into the slots of the second group of mounting top covers 1, and then install and assemble the mounting top covers 1 of other groups in sequence, and then pull the fixed pull rope 6 outward so that the fixed pull rope 6 extends out of the mounting base 3, and the fixed pull rope 6 drives the spring 5 at the tail end to contract and squeeze, and then wind the fixed pull rope 6 around the multiple groups of mounting bases 3, and then pull the fixed pull rope 6 to the original installation base 3. The connecting plate 9 of the base 3 is installed, and the fixing ring 7 is then put on the connecting plate 9, and then the fixing rope 6 is loosened to make the spring spring 5 rebound and tighten the fixing rope 6. At this time, the protrusion of the connecting plate 9 limits the fixing rope 6, and effectively prevents the fixing ring 7 from pulling the spring spring 5 and detaching from the connecting plate 9, thereby connecting and fixing multiple groups of devices, reducing the gap between the devices, and being restricted by the spring spring 5 and the fixing rope 6, the inclination of the device is limited. When the device needs to be cleaned, the intercepting rod 2 can be rotated to expose different parts of the intercepting rod 2 to facilitate its cleaning.

[0030] When installing the electrostatic filter element 4, pull the connecting rod 12 upward so that the connecting rod 12 drives the rotating shaft 11 at the tail end to rise, and the rotating shaft 11 drives the lifting rod 10 at the bottom to rise, and the connecting rod 12 drives the fixed cover 13 to rise, and then rotate the connecting rod 12 so that the connecting rod 12 drives the fixed cover 13 at the tail end to rotate, so that the opening at the top of the installation top cover 1 is exposed to the outside, and then the electrostatic filter element 4 is inserted from the opening at the top of the installation top cover 1, and then the fixed cover 13 is rotated and inserted into the installation top cover 1. At this time, the bottom of the fixed cover 13 is against the electrostatic filter element 4 to limit the electrostatic filter element 4 to prevent a large gap between the electrostatic filter element 4 and the intercepting rod 2.

[0031] Springs 14 are connected to the left and right sides of the inner wall of the fixed cover 13, the front end of the spring 14 is connected to a connecting plate 15, and the surface of the connecting plate 15 is slidably connected to the inner wall of the fixed cover 13, the top of the connecting plate 15 is fixedly connected to a pulling plate 16, the front of the connecting plate 15 is fixedly connected to a fixing block 17, and the surface of the fixing block 17 is slidably connected to the inner wall of the fixed cover 13.

[0032] When installing and disassembling the fixed cover 13, the pull plate 16 is pulled toward the middle, so that the pull plate 16 drives the bottom connecting plate 15 to slide, and the connecting plate 15 drives the front fixed block 17 to slide on the inner wall of the fixed cover 13, so that the fixed block 17 shrinks into the inner wall of the fixed cover 13, and the connecting plate 15 squeezes the spring 14, and then the fixed cover 13 can be pulled out to install the top cover 1. When it is necessary to install, the fixed cover 13 can be pulled out.

[0033] The cover 13 is pressed upward, so that the mounting top cover 1 squeezes the fixing block 17 and the fixing block 17 shrinks into the inner wall of the fixing cover 13, so that the fixing cover 13 can be pressed to the inner wall of the middle part of the mounting top cover 1 and fixed.

[0034] Working principle: pull the pull plate 16 toward the middle to shrink the fixing block 17 into the inner wall of the fixing cover 13, then pull the connecting rod 12 upward to extend the fixing cover 13 out of the mounting cover 1, then rotate the mounting cover 1 to expose the opening at the top of the mounting cover 1, then insert the electrostatic filter element 4 from the opening at the top of the mounting cover 1 to pass through the mounting base 3, then rotate the connecting rod 12 in the opposite direction and press the fixing cover 13 downward to insert the fixing cover 13 into the mounting cover. 1, thereby fixing the electrostatic filter element 4, inserting the limit block 8 into the slot on the right side of the second group of mounting top cover 1, and plugging the subsequent devices in sequence, then pulling out the fixed pull rope 6 of the first group, and winding it around several groups of mounting bases 3, and then pulling the fixed pull rope 6 to the first group of connecting plates 9, so that the fixing ring 7 can be fixed on the connecting plate 9, through the cooperation of the fixed pull rope 6 and the limit block 8, several groups of this device can be picked up and installed at the same time, and it is difficult to deviate, thereby reducing the air leakage rate.
