[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0021] See also Figure 1-4A filter element of a filter element that can be quickly disassembled and assembled comprises a shell 1, a center tube 2 and a filter element 3. A limit block 5 is fixedly installed on the top surface of the shell 1, and a docking groove 6 is provided between the limit block 5 and the shell 1. A fixing ring 4 is fixedly connected to the top surface of the filter element 3, and a clamping block 7 is fixedly connected to the outer side of the fixing ring 4. A plug-in hole 8 is penetrated on the top surface of the clamping block 7, and a plug-in block 9 is provided inside the docking groove 6. A cavity 12 is provided inside the shell 1, and the number of the plug-in blocks 9 is two, and the lower halves of the two plug-in blocks 9 are located inside the cavity 12.

[0022] For further information, see Figure 2 The number of the card block 7 and the limit block 5 is two, the docking groove 6 is adapted to the card block 7, and the plug-in block 9 is adapted to the plug-in hole 8. By setting the number of the card block 7 and the limit block 5 to be two, and setting the docking groove 6 to be adapted to the card block 7, after the user completes the rotation of the card block 7, the card block 7 will be restricted below the limit block 5 and will not move easily. By setting the plug-in block 9 to be adapted to the plug-in hole 8, the plug-in block 9 can be plugged into the plug-in hole 8, so that the card block 7 cannot easily produce a lateral rotation.

[0023] For further information, see Figure 3 A movable pressing block 10 is arranged inside the limit block 5, and the bottom end of the pressing block 10 is fixedly connected to the connecting block 11, and the bottom of the plug-in block 9 is fixedly connected to the top surface of the connecting block 11. By setting the bottom end of the pressing block 10 to be fixedly connected to the connecting block 11, and setting the bottom of the plug-in block 9 to be fixedly connected to the top surface of the connecting block 11, the user can control the positions of the two plug-in blocks 9 at the same time through the pressing block 10, making the use of the device easier.

[0024] Furthermore, a guide rod 13 is fixedly installed at the bottom end of the inner wall of the cavity 12, and a return spring 14 is sleeved on the outer wall of the guide rod 13. The upper end of the return spring 14 is fixedly connected to the connecting block 11, and the lower end of the return spring 14 is fixedly connected to the bottom surface of the inner wall of the cavity 12. By setting the return spring 14 and setting the upper and lower ends of the return spring 14 to connect the connecting block 11 and the bottom surface of the cavity 12 respectively, the connecting block 11 will be pushed upward by the return spring 14 without human power.

[0025] In addition, a through groove compatible with the guide rod 13 is provided inside the plug-in block 9. By providing a through groove compatible with the guide rod 13 inside the plug-in block 9, the plug-in block 9 can move up and down. It should be noted that a through groove compatible with the guide rod 13 is also provided inside the connecting block 11.

[0026] During specific implementation, when the filter element 3 needs to be installed, the filter element 3 needs to be placed inside the housing 1 first, and then the block 7 is aligned with the opening between the two limit blocks 5 and fits to its surface, and then the fixing ring 4 needs to be rotated clockwise, thereby driving the two blocks 7 to rotate at the same time. During the rotation, the two blocks 7 will rotate into the interior of the docking groove 6, and thus be initially limited by the limit block 5. At this time, the fixing ring 4 and the block 7 cooperate with the docking groove 6 to prevent the device from easily detaching from the device without human power.

[0027] At the same time, when the card block 7 is about to be rotated into place, it is necessary to press the pressure block 10 in opposite directions. After being pressed downward, the pressure block 10 will drive the two plug-in blocks 9 to move downward synchronously through the connecting block 11. After the plug-in block 9 completely leaves the docking groove 6, the user can continue to rotate the card block 7. At this time, the card block 7 will not be limited by the plug-in block 9 during the rotation process. After the card block 7 is completely rotated into the docking groove 6, the user can release the pressure block 10. At this time, under the action of the elastic force of the reset spring 14, the connecting block 11 will drive the two plug-in blocks 9 to reset, and the two plug-in blocks 9 will enter the inside of the two plug-in holes 8, and the card block 7 will be horizontally limited. At this time, the installation of the filter element 3 has been completed.

[0028] When disassembly is required, the user only needs to press the pressing block 10 again and rotate the clamping block 7 counterclockwise to eliminate all lateral and longitudinal restrictions on the clamping block 7. At this time, the user can complete the disassembly of the filter element 3 cleanly.

[0029] By setting the clamping block 7 and the limiting block 5 and cooperating with the plug-in hole 8 and the plug-in block 9, the device can quickly complete the installation and removal of the filter element 3, and the operation process is simple and easy to understand, without any operation threshold, and the installation and removal of the filter element 3 can be easily completed by non-professionals.

[0030] At the same time, by setting the plug-in hole 8 and the plug-in block 9 and cooperating with the clamping block 7 and the limiting block 5, the filter element 3 is limited both longitudinally and transversely after installation, so that the installed filter element 3 will not easily fall out of the device, making the installation and use of the filter element 3 more stable.

[0031] Working principle: When the filter element 3 needs to be installed, the filter element 3 needs to be placed inside the housing 1 first, and then the block 7 is aligned with the opening between the two limit blocks 5 and fits to its surface, and then the fixing ring 4 needs to be rotated clockwise to drive the two blocks 7 to rotate at the same time. During the rotation, the two blocks 7 will rotate into the docking groove 6, and will be initially limited by the limit block 5. At this time, the fixing ring 4 and the block 7 cooperate with the docking groove 6 to prevent the device from easily detaching from the device without human power.

[0032] At the same time, when the card block 7 is about to be rotated into place, it is necessary to press the pressure block 10 in opposite directions. After being pressed downward, the pressure block 10 will drive the two plug-in blocks 9 to move downward synchronously through the connecting block 11. After the plug-in block 9 completely leaves the docking groove 6, the user can continue to rotate the card block 7. At this time, the card block 7 will not be limited by the plug-in block 9 during the rotation process. After the card block 7 is completely rotated into the docking groove 6, the user can release the pressure block 10. At this time, under the action of the elastic force of the reset spring 14, the connecting block 11 will drive the two plug-in blocks 9 to reset, and the two plug-in blocks 9 will enter the inside of the two plug-in holes 8, and the card block 7 will be horizontally limited. At this time, the installation of the filter element 3 has been completed.

[0033] When disassembly is required, the user only needs to press the pressing block 10 again and rotate the clamping block 7 counterclockwise to eliminate all lateral and longitudinal restrictions on the clamping block 7. At this time, the user can complete the disassembly of the filter element 3 cleanly.

[0034] By setting the clamping block 7 and the limiting block 5 and cooperating with the plug-in hole 8 and the plug-in block 9, the device can quickly complete the installation and removal of the filter element 3, and the operation process is simple and easy to understand, without any operation threshold, and the installation and removal of the filter element 3 can be easily completed by non-professionals.

[0035] At the same time, by setting the plug-in hole 8 and the plug-in block 9 and cooperating with the clamping block 7 and the limiting block 5, the filter element 3 is limited both longitudinally and transversely after installation, so that the installed filter element 3 will not easily fall out of the device, making the installation and use of the filter element 3 more stable.
