Description

Technical Field

[0001] This utility model relates to the field of air filter technology, specifically to an air filter element mounting housing assembly. Background Technology

[0002] An air filter assembly consists of an air filter housing, an air filter element, and an air filter cover. The air filter element can be detached and installed inside the air filter housing. It is positioned by the engagement of an annular ring at the bottom of the air filter housing and an annular ring on the air filter cover. The air filter element is then sealed and secured by tightening the air filter cover. When the air filter element becomes clogged with dust, it needs to be disassembled, cleaned, and reinstalled. However, the air filter element is only fixed vertically, and its height is relatively high. The horizontal airflow impacting the air filter element for a long time can cause it to deform or even be damaged, resulting in a reduced service life.

[0003] Therefore, the research objective of this utility model is to design an air filter housing assembly that can simultaneously fix the air filter element from both longitudinal and transverse directions while ensuring its sealing and fixation, thereby improving installation stability and extending the service life of the air filter element. Utility Model Content

[0004] In view of the technical problems existing in the prior art, the present invention provides an air filter mounting housing assembly, which can effectively solve the technical problems existing in the prior art.

[0005] The technical solution of this utility model is:

[0006] An air filter mounting housing assembly, comprising:

[0007] The air filter housing has an air inlet and an air outlet on one side and at the bottom, respectively. Inside the air outlet, a limiting ring for limiting the installation of the air filter element is coaxially fixed, and a cover is detachably provided on the top corresponding to the air outlet.

[0008] An air filter element is provided with a through hole connecting the top and bottom. It is detachably inserted into the air filter housing and sleeved on the outside of the limiting ring. Gas enters the air filter housing from the air inlet, is filtered through the air filter element, and is discharged from the air outlet.

[0009] The closing mechanism includes a closing cover and a drive rod that are coaxially fixedly mounted on the cover body;

[0010] A transverse abutment mechanism is provided, wherein a corresponding support frame is fixedly installed on the bottom inner side of the air filter housing, and at least one transverse abutment mechanism is installed on the support frame. The transverse abutment mechanism includes a set of pushing members that are laterally opposite or back-to-back installed on the support frame. The top of the support frame is provided with an embedding hole that is compatible with the drive rod. When the cover is placed on the air filter housing, the drive rod is inserted into the embedding hole until the sealing cover abuts against the support frame and the sealing cover closes the through hole at the top of the air filter element. The drive rod passes through the middle of the two pushing members and pushes the two pushing members outward, so that the pushing members abut against the inner wall of the air filter element.

[0011] The support frame is composed of 2N vertical plates arranged in a circular array and symmetrically arranged in pairs, where N is a positive integer.

[0012] The support frame is horizontally fixed with an installation tube that passes through two symmetrically arranged upright plates. The symmetrically arranged upright plates have mounting holes facing each other, and the mounting holes on different sets of upright plates are staggered vertically. Corresponding connecting rods are movably inserted and installed on both sides of the installation tube, and a set of pushing members are respectively fixed on the outside of the corresponding connecting rod.

[0013] The bottom end of the drive rod is conical, and the top of the opposite side of the two connecting rods is provided with an inclined surface that matches the conical bottom end of the drive rod.

[0014] Both the mounting tube and the connecting rod are provided with corresponding fixing rings. The connecting rod is covered with a corresponding elastic element. The two ends of the elastic element are respectively fixed to the fixing rings provided on the mounting tube and the connecting rod. When the driving rod is inserted into the mounting tube and pushes the connecting rod to move outward synchronously, the elastic element is compressed.

[0015] The enclosure includes a sealing plate that is fitted onto the middle of the air filter element after installation to form a closed shape, a cover piece that covers the top outside of the air filter element, and a connector that is fixedly connected to the cover. The sealing plate, cover piece, and connector are integrally formed.

[0016] Advantages of this utility model:

[0017] 1) This utility model adds a sealing mechanism and a transverse abutment mechanism inside the air filter cartridge shell. The air filter element is longitudinally fixed by the cooperation of the sealing cover and the limiting ring of the sealing mechanism. The air filter element is further fixed by the abutment between the sealing cover and the support frame, and the drive rod passes through the support frame, thereby improving the stability of the longitudinal fixation of the air filter element.

[0018] 2) Further, the cover is guided and installed by the drive rod passing through the support frame. When the drive rod moves downward, it passes between the two connecting rods, and the conical bottom end of the drive rod cooperates with the inclined surface of the connecting rod to push the connecting rod outward. This pushes the two symmetrical pressing parts against the inner side of the air filter element, thereby forming a transverse reinforcing rib to fix the air filter element and improve the transverse stability of the air filter element. After the cover is removed, the pressing parts retract inward under the elastic potential energy of the elastic element, which facilitates the installation of the air filter element and improves the use effect of this utility model.

[0026] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0027] refer to Figure 1-6 An air filter mounting housing assembly, comprising:

[0028] Air filter housing 1, with an air inlet 101 and an air outlet 102 respectively provided on one side and bottom of the air filter housing 1. A limiting ring 2 for limiting the installation of the air filter element 4 is coaxially fixed inside the air outlet 102, and a cover 3 is detachably provided on the top corresponding to the air outlet 102.

[0029] Air filter element 4, which is provided with a through hole connecting the upper and lower parts, is detachably inserted into the air filter housing 1 and sleeved on the outside of the limiting ring 2; gas enters the air filter housing 1 from the air inlet 101, and is then filtered through the air filter element 4 and discharged from the air outlet 102.

[0030] The closing mechanism 5 includes a closing cover 502 and a drive rod 501 that are coaxially fixedly mounted on the cover body 3;

[0031] A transverse abutment mechanism 6 is provided. A corresponding support frame 7 is fixedly installed on the bottom inner side of the air filter housing 1. At least one transverse abutment mechanism 6 is installed on the support frame 7. The transverse abutment mechanism 6 includes a set of pushing members 601 that are laterally opposite or back-to-back installed on the support frame 7. The top of the support frame 7 is provided with an embedding hole that is compatible with the drive rod 501. When the cover 3 is placed on the air filter housing 1, the drive rod 501 is inserted into the embedding hole until the sealing cover 502 abuts against the support frame 7 and the sealing cover 502 closes the through hole at the top of the air filter element 4. The drive rod 501 passes through the middle of the two pushing members 601 and pushes the two pushing members 601 outward, so that the pushing members 601 abut against the inner wall of the air filter element 4.

[0032] This utility model adds a sealing mechanism 5 and a transverse abutment mechanism 6 inside the air filter cartridge shell. The air filter element 4 is longitudinally fixed by the cooperation of the sealing cover 502 and the limiting ring 2 of the sealing mechanism 5. The air filter element 4 is further fixed by the abutment between the sealing cover 502 and the support frame 7, and the drive rod 501 passes through the support frame 7, thereby improving the stability of the longitudinal fixation of the air filter element 4.

[0033] The support frame 7 is composed of 2N vertical plates arranged in a circular array and symmetrically arranged in pairs, where N is a positive integer.

[0034] The support frame 7 is horizontally fixed with an installation tube 602 that passes through two symmetrically arranged upright plates. The symmetrically arranged upright plates have mounting holes facing each other, and the mounting holes on different sets of upright plates are staggered vertically. Corresponding connecting rods 603 are movably inserted and installed on both sides of the installation tube 602. A set of pushing members 601 are respectively fixed on the outside of the corresponding connecting rods 603.

[0035] The bottom end of the drive rod 501 is conical, and the top of the two connecting rods 603 on opposite sides is provided with an inclined surface that matches the conical bottom end of the drive rod 501.

[0036] Both the mounting tube 602 and the connecting rod 603 are provided with corresponding fixing rings 604. The connecting rod 603 is covered with a corresponding elastic element 605. The two ends of the elastic element 605 are respectively fixed to the fixing rings 604 provided on the mounting tube 602 and the connecting rod 603. When the driving rod 501 is inserted into the mounting tube 602 and pushes the connecting rod 603 to move outward synchronously, the elastic element 605 is compressed.

[0037] The cover 3 is further guided and installed by the drive rod 501 passing through the support frame 7. When the drive rod 501 moves downward, it passes between the two connecting rods 603. The conical bottom end of the drive rod 501 cooperates with the inclined surface of the connecting rod 603 to push the connecting rod 603 outward. This pushes the two symmetrical pressing parts 601 against the inner side of the air filter element 4, thereby forming a transverse reinforcing rib to fix the air filter element 4 and improve the stability of the transverse fixation of the air filter element 4. After the cover 3 is removed, the pressing parts 601 retract inward under the elastic potential energy of the elastic part 605, which facilitates the installation of the air filter element 4 and improves the use effect of this utility model.

[0038] The enclosure 502 includes a sealing plate 5011 that is installed and fitted onto the middle of the air filter element 4 to form a closed shape, a cover 5012 that covers the outer side of the top of the air filter element 4, and a connector 5013 that is fixedly connected to the cover body 3. The sealing plate 5011, the cover 5012 and the connector 5013 are integrally formed.

[0039] The enclosure is configured as an integrally formed sealing plate 5011, cover 5012 and connector 5013. The sealing plate 5011 and cover 5012 work together to seal the air filter element 4 from the inside and outside, improving the stability of the seal.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
