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

[0014] Please refer to Figures 1-4This utility model provides a technical solution: a high-flow air filter bag, including a frame 1, three filter bag bodies 2 fixedly installed at the bottom of the frame 1, side plates 3 fixedly connected to both sides of the bottom of the frame 1, a crossbar 4 provided at the bottom between two side plates 3, a fixed cylinder 7 fixedly connected to the bottom position of one side plate 3, a spring 8 fixedly connected to one side inside the fixed cylinder 7, a housing 12 fixedly installed at the bottom of one side plate 3 at the other end, the other end of the crossbar 4 passing through the interior of the side plate 3 and the housing 12 in sequence, a ball bearing 11 rollingly installed on one side of the crossbar 4, a motor 13 fixedly installed at the center of the top inside the housing 12, a cam 15 provided at the lower end of the motor 13, and a groove 16 opened on the outer wall of the cam 15.

[0015] One end of the crossbar 4 passes through the interior of the fixed cylinder 7 and is fixedly connected to one side of the spring 8, ensuring that the crossbar 4 has a certain buffering and restoring ability when subjected to external force, providing a power basis for subsequent automatic shaking.

[0016] Guide blocks 10 are fixedly connected to one side of the top and bottom of the crossbar 4. Guide grooves 9 are opened on one side of the top and bottom of the fixed cylinder 7. The top and bottom of the two guide blocks 10 extend into the interior of the two guide grooves 9 and slide to connect with the inner wall of the guide grooves 9, which restricts the movement trajectory of the crossbar 4, so that it can only move in a straight line along the direction of the guide grooves 9, thus ensuring the stability and directionality of the shaking.

[0017] The motor 13 is fixedly connected to the main shaft 14 through its bottom output end. The lower end of the main shaft 14 is fixedly connected to the top of the cam 15, so that the motor 13 can drive the cam 15 to rotate efficiently and stably, providing a power source for the entire vibration system.

[0018] One side of the ball bearing 11 extends into the interior of the slide groove 16 and rolls in contact with the inner wall of the slide groove 16, reducing the friction between the cam 15 and the crossbar 4, allowing the crossbar 4 to move more smoothly with the rotation of the cam 15, thus improving the efficiency and smoothness of the vibration.

[0019] The top of the crossbar 4 is fixedly connected to the bottom of each of the three filter bag bodies 2, and the center of the bottom of each of the three filter bag bodies 2 is fixedly connected to the hook 6. The three hooks 6 are respectively hooked to the three fixed rings 5, ensuring that the filter bag bodies 2 can move stably with the crossbar 4 during the shaking process, thereby achieving effective shaking cleaning.

[0020] Working principle: when the air filter system starts, the motor 13 starts to work, through the main shaft 14 drives the cam 15 to rotate, with the rotation of the cam 15, the slide groove 16 opened in its outer wall and the ball 11 on one side of the crossbar 4 interact with each other, the ball 11 rolls inside the slide groove 16, due to the change of the cam 15 contour, the pressure and direction of the ball 11 also change, in turn, to push the crossbar 4 to move back and forth, one end of the crossbar 4 is fixedly connected with the spring 8 inside the fixed cylinder 7, the spring 8 provides the necessary buffer and reset force for the reciprocating movement of the crossbar 4, at the same time, the guide block 10 at the top and bottom of the crossbar 4 slides in the guide groove 9 of the fixed cylinder 7, ensuring that the crossbar 4 can only move linearly along the direction of the guide groove 9, enhancing the stability and directionality of the shaking, with the reciprocating movement of the crossbar 4, through the structure of the fixed ring 5 and the hook 6 connected with the bottom of the three filter bag bodies 2, the filter bag body 2 can stably shake left and right with the crossbar 4, this shaking effectively prevents dust and impurities from adhering to the inner wall of the filter bag body 2 for a long time, thereby realizing the automatic shaking and cleaning function of the filter bag.

[0021] In summary: through the design of the crossbar 4, the fixed cylinder 7, the spring 8, the ball 11, the motor 13, the cam 15 and the slide groove 16, when the motor 13 is started, the cam 15 starts to rotate, in the rotation process of the cam 15, the ball 11 slides flexibly inside the slide groove 16, moves up and down with the change of the cam 15 contour, this movement mechanism is effectively converted into the reciprocating horizontal movement of the crossbar 4 through the elastic action of the spring 8. Since one end of the crossbar 4 is connected with the fixed cylinder 7 through the spring 8, it is ensured that the spring 8 can always keep the ball 11 at one end of the crossbar 4 in close contact with the slide groove 16 on the cam 15 when the cam 15 rotates, therefore, with the continuous rotation of the cam 15, the crossbar 4 will move back and forth horizontally, in turn, to drive the three filter bag bodies 2 to shake left and right, this shaking can effectively prevent dust from adhering to the inner wall of the filter bag body 2 for a long time, greatly facilitating the subsequent cleaning work, at the same time, the design also prevents the filter bag body 2 from being blocked due to dust accumulation, ensures the smooth passage of airflow, thereby maintaining the high filtering performance and prolonging the service life of the filter bag.
