Technical Field

[0001] The utility model relates to the technical field of filter elements, and particularly relates to a folding filter element for air compressor gas purification. Background Technique

[0002] The filter element is an important component used in equipment such as water treatment systems, air purifiers, and automobile engines. It is used to remove impurities such as suspended solids, solid particles, chemical substances, odors, bacteria, and viruses, thereby improving water quality or purifying the air.

[0003] The existing utility model patent with the application number: CN202322162309.8 proposes a folding filter element. For this folding filter element, through the setting of the connection component, when the filter membrane needs to be replaced, all the fixing nuts on the stud are unscrewed, then the top cover is lifted upward, after replacing the internal filter membrane, the through hole on the snap ring is aligned with the stud on the fixed ring, and then the top cover is inserted back, and the fixing nuts are screwed on again, so that the filter membrane can be replaced quickly and conveniently, which is convenient for the replacement of the filter membrane and easy to use.

[0004] After the through hole on the snap ring in the device is aligned with the stud on the fixed ring and the top cover is inserted back and the fixing nuts are screwed on again, the staff needs to screw multiple nuts, and the operation time is relatively long, which reduces the practicability of the device. Therefore, a folding filter element for air compressor gas purification is provided to solve the above problems. Content of the Utility Model

Detailed Description of the Preferred Embodiment

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: a foldable filter element for air compressor gas purification, including an outer support cylinder 1. A top cover 2 is provided at the top of the outer support cylinder 1. A fixed ring 3 is fixedly connected to the bottom of the top cover 2. A connecting ring 5 is fixedly connected to the outside of the outer support cylinder 1. Two sliding blocks 13 are symmetrically and slidably connected inside the connecting ring 5. A clamping block 4 that cooperates with the fixed ring 3 is fixedly connected to the top of the sliding block 13. When the filter membrane 7 needs to be replaced, the user pulls the pulling block 10. The pulling block 10 drives the clamping block 4 away from the fixed ring 3 through the sliding block 13, and then the top cover 2 can be pulled to drive the fixed ring 3 away from the connecting ring 5. After replacing the internal filter membrane 7, the top cover 2 is pressed so that the fixed ring 3 contacts the connecting ring 5, and the limiting block 11 enters the inside of the limiting groove 14 for limiting. At the same time, the sliding block 13 drives the clamping block 4 to fix the fixed ring 3 under the elastic force of the telescopic spring 12, which can quickly connect the fixed ring 3 and the connecting ring 5.

[0023] Furthermore, an inner support cylinder 15 is fixedly connected inside the outer support cylinder 1. A filter membrane 7 is fixedly connected between the outer support cylinder 1 and the inner support cylinder 15. Air passes through the filter membrane 7 to filter out smaller impurities in the air that have not been filtered out by the outer support cylinder 1.

[0024] Furthermore, sliding grooves 8 are symmetrically formed inside the connecting ring 5, and a limiting rod 9 is fixedly connected inside the sliding grooves 8. The limiting rod 9 is slidably connected with the slider 13, which facilitates the limitation of the slider 13 and prevents the slider 13 from shifting during movement.

[0025] Furthermore, a telescopic spring 12 is sleeved outside the limiting rod 9 and on one side of the slider 13. The slider 13 drives the clamping block 4 to fix the fixed ring 3 under the elastic force of the telescopic spring 12.

[0026] Furthermore, a pulling block 10 is fixedly connected to the bottom of the slider 13. The user pulls the pulling block 10, and the pulling block 10 pulls the slider 13 to move. Transverse strip-shaped holes 6 are equidistantly formed inside the outer support cylinder 1, so that air enters through the transverse strip-shaped holes 6 formed on the surface of the outer support cylinder 1, and some larger impurities mixed in the air are filtered out.

[0027] Furthermore, limiting blocks 11 are fixedly connected to the top of the connecting ring 5 at equal intervals, and a limiting groove 14 for cooperating with the limiting blocks 11 is formed inside the fixed ring 3. When the top cover 2 is pressed, the fixed ring 3 contacts the connecting ring 5, and the limiting blocks 11 enter the inside of the limiting groove 14 for limitation.

[0028] During operation, air enters through the transverse strip-shaped holes 6 formed on the surface of the outer support cylinder 1, and some larger impurities mixed in the air are filtered out. The air then passes through the filter membrane 7 to filter out smaller impurities in the air that the outer support cylinder 1 has not filtered out. When the filter membrane 7 needs to be replaced, the user pulls the pulling block 10, and the pulling block 10 drives the clamping block 4 to move away from the fixed ring 3 through the slider 13, so that the top cover 2 can be pulled to drive the fixed ring 3 to move away from the connecting ring 5. After the internal filter membrane 7 is replaced, the top cover 2 is pressed so that the fixed ring 3 contacts the connecting ring 5, and the limiting blocks 11 enter the inside of the limiting groove 14 for limitation. At the same time, the slider 13 drives the clamping block 4 to fix the fixed ring 3 under the elastic force of the telescopic spring 12, which can quickly connect the fixed ring 3 and the connecting ring 5, reduce the operation time, and improve the practicability of the device.
