Description

Technical Field

[0001] This application relates to the field of filter technology, and in particular to a pleated filter. Background Technology

[0002] The filter element includes an upper cover, a lower cover, and a filter assembly. The filter assembly is located between the upper and lower covers. When installing the filter element, the connecting tube of the upper cover needs to be inserted into the housing interface. Normally, the connecting tube of the filter element is simply connected to the housing interface. When the filter element is subjected to external impact, the connecting tube of the filter element moves or swings relative to the housing interface, which creates a gap between the connecting tube and the housing interface. Then, the original filter material will pass through the gap between the connecting tube and the housing interface, reducing the filtration efficiency of the filter element. Utility Model Content

[0003] The purpose of this invention is to provide a corrugated filter element that addresses the shortcomings and deficiencies of existing technologies.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The device includes an upper end cover, a lower end cover, and a filter assembly. The filter assembly is located between the upper end cover and the lower end cover. The upper end cover has a connecting tube at its upper end and a stabilizing ring at its upper end. The stabilizing ring is located on the outer periphery of the connecting tube and is clamped to the housing interface with the connecting tube. Multiple locking blocks are evenly arranged on the outer periphery of the outer end of the connecting tube and are locked to the inner wall of the housing interface. A sealing ring is fitted around the outer periphery of the connecting tube.

[0006] Preferably, a plurality of locking plates are uniformly arranged inside the peripheral sidewall of the stabilizing ring, and a driving member is provided on the outer periphery of the stabilizing ring, which can drive one end of the locking plate to bend inward.

[0007] Preferably, the driving component includes a mounting ring seat and a plurality of eccentric wheels, the plurality of eccentric wheels being uniformly rotatably connected to the peripheral sidewall of the mounting ring seat, and the plurality of eccentric wheels corresponding to the plurality of locking plates.

[0008] Preferably, the mounting ring seat has a plurality of rotating grooves evenly provided on its peripheral sidewall, the eccentric wheel is rotatably connected in the rotating groove, the sidewall of the eccentric wheel is provided with a positioning block, and the mounting ring seat has two positioning grooves evenly provided on the sidewall of the rotating groove for the positioning block to be engaged and fixed.

[0009] Preferably, an anti-slip plate is provided on the inner sidewall of one end of the locking piece.

[0010] Preferably, the eccentric wheel is provided with anti-slip strips on its periphery.

[0011] Preferably, the outer side of the outer end of the card block is provided with a beveled surface.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. When the filter element needs to be installed on the housing interface, insert the connecting tube of the upper end cover into one end of the housing interface, so that multiple locking blocks engage with the inner side wall of one end of the housing interface until one end of the housing interface abuts between the stabilizing ring and the connecting tube. Then rotate the eccentric wheel, so that the outer side of the eccentric wheel rotates inward. After that, the eccentric wheel pushes the locking plate, so that one end of the locking plate bends inward, so that the inner side of the locking plate presses against the side wall of the housing interface, thereby locking the housing interface to the connecting tube. After that, the filter element will not move relative to the housing interface under the action of external force, thus improving the stability of the filter element.

[0014] 2. When one end of the locking plate bends inward under the action of the eccentric wheel, the anti-slip sidewall on the inner side of the locking plate adheres tightly to the housing interface, so that the filter element will not rotate relative to the housing interface, further improving the stability of the filter element.

[0015] 3. When the thin sidewall of the eccentric wheel faces inward, the positioning block of the eccentric wheel is engaged in one of the positioning grooves, fixing the eccentric wheel in the rotation groove. When the thick sidewall of the eccentric wheel faces inward, the positioning block of the eccentric wheel is engaged in the other positioning groove, fixing the eccentric wheel in the rotation groove, thus improving the stability of the eccentric wheel.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] This application discloses a corrugated filter element.

[0023] Reference Figure 1 and Figure 2 It includes an upper cover 1, a lower cover 2, and a filter assembly 3. The filter assembly 3 includes an outer frame 4, a filter screen 5, and an inner frame 6. The filter screen 5 is installed and fixed on the outer periphery of the inner frame 6. The upper end of the inner frame 6 is inserted and fixed to the lower end face of the upper cover 1, and the lower end of the inner frame 6 is inserted and fixed to the upper end face of the lower cover 2. The upper end of the outer frame 4 is fixed to the outer periphery of the upper cover 1, and the lower end of the outer frame 4 is fixed to the outer periphery of the lower cover 2. A connecting pipe 22 is integrally provided on the upper end face of the upper cover 1.

[0024] Reference Figure 2 , Figure 3 and Figure 4 The connecting pipe 22 has four evenly spaced mounting grooves 7 on its outer circumference. A locking block 8 is integrally formed at the bottom of each mounting groove 7. The vertical cross-section of the locking block 8 is "L"-shaped. A ring groove 9 is formed on the outer circumference of the connecting pipe 22, and a sealing ring 10 is embedded within the ring groove 9. The upper end of the connecting pipe 22 is inserted into one end of the housing interface 25. The outer side of one end of the locking block 8 is pressed against the inner wall of the housing interface 25, and the outer circumference of the sealing ring 10 abuts against the inner wall of the housing interface 25.

[0025] The outer side wall of the outer end of the locking block 8 is provided with a beveled surface 11. The beveled surface 11 facilitates the insertion of the connecting pipe 22 into the housing interface 25.

[0026] A stabilizing ring 23 is fitted around the outside of the connecting pipe 22. The stabilizing ring 23 is fixed to the upper end face of the upper end cover 1 by bolts. An annular stabilizing groove 24 is formed between the stabilizing ring 23 and the connecting pipe 22. One end of the housing interface 25 is inserted into the stabilizing groove 24. Four connecting grooves 12 are evenly opened in the peripheral side wall of the stabilizing ring 23. A locking piece 13 is integrally provided on the side wall of the connecting groove 12. The locking piece 13 is arc-shaped. A driving component 14 is placed on the outside of the stabilizing ring 23. The driving component 14 includes a mounting ring seat 15 and four offset... The eccentric wheel 16 and the mounting ring seat 15 are fixed to the upper end face of the upper end cover 1 by bolts. Four rotating grooves 17 are evenly formed in the circumferential sidewall of the mounting ring seat 15. The eccentric wheel 16 is rotatably connected within the rotating grooves 17. A positioning block 18 is integrally formed on the sidewall of the eccentric wheel 16. The positioning block 18 is hemispherical. Two positioning grooves 19 are evenly formed on the sidewall of the rotating grooves 17 of the mounting ring seat 15. The two positioning grooves 19 are located on both sides of the rotating shaft of the eccentric wheel 16 and are set at a 180° angle. When the thin sidewall of the eccentric wheel 16 is turned inward, the positioning block 18 of the eccentric wheel 16 is engaged in one of the positioning grooves 19. When the thick sidewall of the eccentric wheel 16 is turned inward, the positioning block 18 of the eccentric wheel 16 is engaged in the other positioning groove 19.

[0027] An anti-slip plate 20 is glued and fixed to the inner wall of one end of the locking plate 13. When one end of the locking plate 13 bends inward under the action of the eccentric wheel 16, the side wall of the anti-slip plate 20 on the inner side of one end of the locking plate 13 is pressed against the housing interface 25, so that the filter element will not rotate relative to the housing interface 25.

[0028] Multiple anti-slip strips 21 are integrally provided on the periphery of the eccentric wheel 16. When the eccentric wheel 16 needs to be rotated, the multiple anti-slip strips 21 can increase the friction on the periphery of the eccentric wheel 16, making it easier to drive the eccentric wheel 16 to rotate.

[0029] The implementation principle of a corrugated filter element disclosed in this application is as follows:

[0030] Insert the connecting tube 22 of the upper end cover 1 into one end of the housing interface 25, so that multiple locking blocks 8 are engaged with the inner side wall of one end of the housing interface 25 until one end of the housing interface 25 abuts against the stabilizing ring 23 and the connecting tube 22. Then rotate the eccentric wheel 16 so that the outer side of the eccentric wheel 16 rotates inward. Then the eccentric wheel 16 pushes the locking plate 13 so that one end of the locking plate 13 bends inward, so that the inner side of the locking plate 13 presses against the side wall of the housing interface 25, thereby locking the housing interface 25 onto the connecting tube 22. After that, the filter element will not move relative to the housing interface 25 under the action of external force.

[0031] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
