Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4This utility model provides a technical solution: an energy-saving medium-efficiency composite filter bag, including a connecting seat 1, a filter bag body 2 is provided on one side of the connecting seat 1, an mounting seat 3 is fixedly connected to the outer end of one side of the connecting seat 1, an mounting groove 5 is provided in the center of one side of the mounting seat 3, a connecting plate 4 is fixedly connected to one side of the filter bag body 2, one side of the connecting plate 4 extends into the interior of the mounting groove 5 and engages with the mounting groove 5, a fixed sliding groove 6 is provided in the interior of the mounting seat 3 corresponding to the top and bottom of the mounting groove 5, a moving groove 13 is provided on one side of the top and bottom of the connecting plate 4, a trapezoidal fixing block 12 is provided in the interior of the moving groove 13, and the opposite sides of the two trapezoidal fixing blocks 12 respectively extend into the interior of the two fixed sliding grooves 6 and engage with the fixed sliding grooves 6.

[0015] The connecting plate 4 has sliding grooves 14 on both sides of the corresponding moving groove 13. The bottom of both sides of the trapezoidal fixing block 12 is fixedly connected to sliders 15. The side of the slider 15 away from the trapezoidal fixing block 12 passes through the interior of the sliding groove 14 and is slidably connected to the sliding groove 14.

[0016] The slide groove 14 is internally fixedly connected to a limiting rod 16, which is sleeved and slidably connected to the slider 15.

[0017] Two trapezoidal fixing blocks 12, which are set at the top and bottom respectively, are fixedly connected to two sides of opposite ends of each other with a return spring 17. The side of the return spring 17 away from the trapezoidal fixing block 12 is fixedly connected to the bottom of the moving groove 13.

[0018] A bidirectional damping rod 18 is fixedly installed inside the connecting plate 4 at the center between the two moving slots 13. The top and bottom of the bidirectional damping rod 18 are respectively fixedly connected to the center of the opposite side of the two trapezoidal fixing blocks 12.

[0019] The two fixed sliding grooves 6, which are set at the top and bottom respectively, extend into the interior of the connecting seat 1 on opposite sides. A sliding abutment 8 is slidably connected to the center position of the fixed sliding groove 6. The opposite sides of the two sliding abutments 8, which are set at the top and bottom respectively, contact the opposite ends of the two trapezoidal fixed blocks 12.

[0020] A movable groove 7 is provided on one side of the fixed sliding groove 6. A movable plate 9 is fixedly connected to the top position of one side of the sliding abutment plate 8. One side of the movable plate 9 extends through to the outside of the connecting seat 1 and is fixedly connected to a push plate 11. A support rod 10 is fixedly connected to the center of the movable groove 7. The support rod 10 is sleeved with the movable plate 9 and slidably connected.

[0021] Working principle: When the filter bag body 2 needs to be replaced, the user first holds the push plate 11 and pushes it inward. The push plate 11 is connected to the sliding abutment plate 8 through the movable plate 9. Therefore, pushing the push plate 11 will drive the movable plate 9 and the sliding abutment plate 8 to move together. The sliding abutment plate 8 slides along the support rod 10 in the movable groove 7. The support rod 10 ensures the smoothness and straightness of the movement of the sliding abutment plate 8 and avoids deviation or jamming. As the sliding abutment plate 8 moves, it gradually separates from the opposite end of the trapezoidal fixing block 12. Due to the elastic action of the return spring 17, the trapezoidal fixing block 12 begins to retract inward (i.e., towards the moving groove 13) after the sliding abutment plate 8 is no longer pressing it. When the trapezoidal fixing block 12 is completely retracted into the moving groove 13, their locking relationship with the fixed sliding groove 6 is released. At this time, the connecting plate 4 and the filter bag body 2 on it are no longer fixed and can be freely pulled out from the mounting groove 5. The user takes out the old filter bag body 2 together with the connecting plate 4 from the mounting groove 5.

[0022] In summary, this energy-saving medium-efficiency composite filter bag achieves a quick connection between the filter bag body 2 and the connecting seat 1 through a simple snap-fit ​​connection between the connecting plate 4 and the mounting groove 5. This snap-fit ​​method requires no special tools and can be completed by simple manual operation, greatly simplifying the replacement process and improving the convenience of operation. At the same time, the snap-fit ​​mechanism between the trapezoidal fixing block 12 and the fixed sliding groove 6 further enhances the stability of the connection, ensuring the stability of the filter bag during use, and also provides a reliable locking and unlocking mechanism for replacement. The sliding connection design between the sliding groove 14 and the limiting rod 16 ensures the stability and guidance of the trapezoidal fixing block 12 during movement, avoiding damage caused by improper disassembly. The introduction of the return spring 17 allows the trapezoidal fixing block 12 to automatically return to its original position after disassembly, reducing deformation or damage caused by improper manual operation. The design of the bidirectional damping rod 18 not only enhances the synchronization between the trapezoidal fixing blocks 12, but also plays a buffering role, further reducing the impact and damage during disassembly, thereby extending the service life of the filter bag and its connecting parts.
