[0019] The embodiment of the present application discloses a quick-opening mechanism for a filter. Refer to Figure 1 and Figure 2and Figure 3 , including a filter body 1. A first connecting ring 2 is fixedly installed on the top surface of the filter body 1. Four connecting blocks 3 are fixedly installed on the bottom surface of the first connecting ring 2. A rotating shaft is fixedly installed in the middle of each of the two connecting blocks 3. A rotating block 4 is sleeved on the outer side of each of the two rotating shafts. A connecting rod 5 is fixedly installed on one side of each of the two rotating blocks 4. Threads are provided at the top ends of the two connecting rods 5. A first threaded sleeve 6 is threadedly installed at one end of each of the two connecting rods 5. A limiting ring 7 is fixedly installed at one end of each of the two first threaded sleeves 6. A second threaded sleeve 8 is fixedly installed on the top surface of each of the two limiting rings 7. Four handle blocks 16 are fixedly installed on the outer side of each of the two second threaded sleeves 8. After the second connecting ring 9 is engaged with the first connecting ring 2, then by holding the handle blocks 16 by hand and rotating the rotating block 4 around the rotating shaft of the connecting block 3, the connecting rod 5 and the first threaded sleeve 6 are further rotated, so that the limiting ring 7 rotates to the top surface of the second connecting ring 9, and the connecting rod 5 and the first threaded sleeve 6 rotate to be engaged with the second engaging hole of the first connecting ring 2. Then rotate the handle block 16 to move the first threaded sleeve 6 along the outer side of the connecting rod 5, so that the limiting ring 7 is close to the top surface of the second connecting ring 9, achieving the function of convenient fixing and disassembly.

[0020] Refer to Figure 3 , two first engaging holes are provided on the outer side of the first connecting ring 2, and the first engaging holes facilitate the rotation angle of the connecting rod 5 and the first threaded sleeve 6.

[0021] Refer to Figure 2 , a second connecting ring 9 is snap-connected to one side of the first connecting ring 2. Two second engaging holes are provided on the outer side of the second connecting ring 9. The closing plug 10 of the second connecting ring 9 is embedded along the inner side wall of the circular groove of the filter body 1, so that the second connecting ring 9 is aligned with the outer side of the first connecting ring 2.

[0022] Refer to Figure 2 , a closing plug 10 is fixedly installed on the bottom surface of the second connecting ring 9. The closing plug 10 is engaged with the circular groove of the first connecting ring 2, and the closing plug 10 plays a role in increasing the sealing.

[0023] Refer to Figure 4, a ferrule I (11) and a ferrule II (12) are sleeved on the outer sides of the connecting ring I (2) and the connecting ring II (9). A limiting block (17) is fixedly installed on one side of each of the ferrule I (11) and the ferrule II (12). Fixing blocks I (13) and fixing blocks II (14) are fixedly installed on both sides of the ferrule I (11) and the ferrule II (12). A screw rod (15) is threadedly installed on one side of the ferrule I (11). One ends of the two screw rods (15) penetrate through and are connected to the fixing block II (14) from the outside of the fixing block I (13). By sleeving one side of the ferrule I (11) and the ferrule II (12) on the outer sides of the connecting ring I (2) and the connecting ring II (9), the limiting block (17) is close to the top surface of the connecting ring II (9), and the limiting ring (7) is located in the placement grooves of the ferrule I (11) and the ferrule II (12) and fits. Then, by passing the screw rod (15) through the ferrule I (11) and connecting it with the ferrule II (12) and rotating, the effect of convenient assembly and disassembly can be achieved. It is also possible not to install the rotating block (4), the connecting rod (5), the thread sleeve I (6), the limiting ring (7), the thread sleeve II (8), and the handle block (16), and directly clamp the connecting ring II (9) and the connecting ring I (2) through the ferrule I (11) and the ferrule II (12), and continue the above operation to achieve the effect of convenient assembly and later disassembly.

[0024] The implementation principle of the quick-opening mechanism of a filter in an embodiment of the present application is as follows: First, embed the closing plug (10) of the connecting ring II (9) along the inner side wall of the circular groove of the filter body (1) so that the outer sides of the connecting ring II (9) and the connecting ring I (2) are aligned. Second, after the connecting ring II (9) and the connecting ring I (2) are clamped, then lift the handle block (16) and rotate the rotating block (4) around the rotating shaft of the connecting block (3), further rotating the connecting rod (5) and the thread sleeve I (6) so that the limiting ring (7) rotates to the top surface of the connecting ring II (9), and the connecting rod (5) and the thread sleeve I (6) rotate to be clamped with the second clamping hole of the connecting ring I (2). Then rotate the handle block (16) to move the thread sleeve I (6) along the outside of the connecting rod (5) so that the limiting ring (7) is close to the top surface of the connecting ring II (9). Finally, by sleeving one side of the ferrule I (11) and the ferrule II (12) on the outer sides of the connecting ring I (2) and the connecting ring II (9), the limiting block (17) is close to the top surface of the connecting ring II (9), and the limiting ring (7) is located in the placement grooves of the ferrule I (11) and the ferrule II (12) and fits. Then, by passing the screw rod (15) through the ferrule I (11) and connecting it with the ferrule II (12) and rotating, the effect of convenient assembly and disassembly can be achieved. It is also possible not to install the rotating block (4), the connecting rod (5), the thread sleeve I (6), the limiting ring (7), the thread sleeve II (8), and the handle block (16), and directly clamp the connecting ring II (9) and the connecting ring I (2) through the ferrule I (11) and the ferrule II (12), and continue the above operation to achieve the effect of convenient assembly and later disassembly.
