[0025] It should be noted here that: by setting the telescopic assembly, a guiding and resetting function is provided for the movement of the pressing arc plate 403.

[0026] See also Figure 3 and Figure 4 The driving assembly shown in the figure includes a driving ring 601 sleeved on the side wall of the mounting rod 402, the driving ring 601 is fixedly connected to the driving rod 602 on the side close to the arc plate 403, the side wall of the telescopic rod 502 is fixedly connected to the driving plate 603, the driving plate 603 is arranged opposite to the driving rod 602, and the driving plate 603 is provided with an inclined surface 604 on the side close to the driving rod 602;

[0027] It should be noted here that: by setting the driving assembly, it is convenient to push each of the pressing arc plates 403 to move away from each other.

[0028] See also Figure 3 and Figure 4 , each driving ring 601 in the figure is arranged in an arc shape close to one side of the annular ring 2;

[0029] It should be noted here that: by setting the driving ring 601 close to the side of the annular ring 2 in an arc shape, a guiding effect is provided for the flow of the airflow.

[0030] See also Figure 2 , the driving rings 601 shown in the figure are connected by a plurality of fixing rods 605;

[0031] It should be noted here that: through the provision of multiple fixing rods 605, the driving rings 601 are connected, thereby driving the driving rings 601 to move synchronously.

[0032] Working principle: When the filter bag body 1 is used, the filter bag body 1 is first placed in the filter bin, and the annular ring 2 at the open end of the filter bag body 1 is abutted against the side wall of the filter bin. When the annular ring 2 abuts against the side wall of the filter bin, the annular ring 2 is fixed under the magnetic effect of the flexible magnetic strip 3, and the filter bag body 1 is further fixed. The operation is simple and the implementation is convenient.

[0033] After the filter bag body 1 is installed in the filter bin, when the gas to be filtered enters the filter bag body 1, when the pressure of the gas to be filtered is relatively large, it will impact the surface of the drive ring 601 and push the drive ring 601 to move away from the annular ring 2. In the process of the drive ring 601 moving away from the annular ring 2, each drive rod 602 will be driven to abut against the inclined surface 604 on the drive plate 603, so that under the mutual force and the guiding action of the telescopic component, each pressing arc plate 403 is pushed to move away from each other. In the process of each pressing arc plate 403 moving away from each other, the filter bag body 1 will be pushed, so that the filter bag body 1 will expand. The expanded filter bag body 1 can increase the tightness of the contact surface between the filter bag body 1 and the filter device, so that the filter bag body 1 fits more closely to the device, reducing the possibility of gas leakage from the gap between the filter bag body 1 and the device. At the same time, this tight fit helps to enhance the sealing of the entire filtration system, thereby preventing the filter bag body 1 from loosening or falling off due to gas impact or pressure changes.
