[0025] Reference Figure 2-Figure 3An indicator mark is provided on the side outer wall of the adjustment plate 62, and an anti-sticking layer is fixedly connected to the side outer wall of the screening arc disk 65. The outer walls on both sides of the adjustment plate 62 are slidably connected with an isolation cover 66. The outer wall of the filter box 63 is wrapped by setting the isolation cover 66. The isolation cover 66 is fixedly connected to the bottom outer wall of the cover plate 2. The isolation cover 66 is slidably connected to the side outer wall of the filter box 63. The top outer wall of the filter box 1 is fixedly connected with an injector 3. The pharmaceutical liquid is discharged by setting the injector 3. One end of the injector 3 is fixedly connected with a liquid flow port 4. The liquid flow port 4 is fixedly connected to the bottom inner wall of the cover plate 2. The bottom outer wall of the filter box 1 is fixedly connected with a liquid outlet 5. The filtered pharmaceutical liquid is discharged by setting the liquid outlet 5.

[0026] Reference Figure 3-Figure 4 The anti-blocking mechanism 7 includes an annular groove 71, which is provided on the side outer wall of the filter box 1.
