[0019] The outer wall of the vertical axis 7 is fixedly connected with a plurality of fan-shaped dispersion pieces 8, and the outer wall of the fan-shaped dispersion piece 8 is provided with dispersion holes 9. When the filter medium impacts the fan-shaped dispersion piece 8, the fan-shaped dispersion piece 8 generates a driving force to rotate the vertical axis 7, and the filter medium is dispersed through the dispersion holes 9 and the fan-shaped dispersion piece 8. The outer walls of the bottom cover 1 and the top cover 2 are provided with annular mounting grooves, and the inner wall of the annular mounting groove is fixedly connected with an inner protective net 10, a filter membrane 11, an activated carbon layer 12 and an outer protective net 13. The filter membrane 11 is sleeved on the outer wall of the inner protective net 10, and the activated carbon layer 12 is sleeved on the outer wall of the filter membrane 11. Filtration is performed through the filter membrane 11 and the activated carbon layer 12. The outer protective net 13 is sleeved on the outer wall of the activated carbon layer 12, and a pressure relief mechanism is provided on the outer wall of the bottom cover 1.

[0020] Depend on Figure 1-Figure 3 As shown, the pressure relief mechanism includes a sealing plate 16, a plurality of pressure relief holes 14 are provided on the outer wall of the bottom cover 1, an annular hollow groove 18 is provided on the outer wall of the bottom cover 1, a plurality of springs 15 are fixedly connected to the inner wall of the annular hollow groove 18, the outer wall of the spring 15 is fixedly connected to the outer wall of the sealing gasket 17, and the spring 15 drives the sealing gasket 17 and the sealing plate 16 to reset.

[0022] Working principle: When in use, the filter medium enters the filter element from the fan-shaped hole 4 of the top cover 2, and is filtered through the filter membrane 11 and the activated carbon layer 12. When the filter medium impacts the fan-shaped dispersion sheet 8, the fan-shaped dispersion sheet 8 generates a driving force to rotate the vertical axis 7. The rotation of the vertical axis 7 causes the fan-shaped dispersion sheet 8 to rotate, so that the filter medium is dispersed, which is convenient for uniform filtration and avoids excessive concentration. At the same time, when the pressure is too high, the sealing plate 16 and the sealing gasket 17 move outward. After moving to a certain distance, the filter medium enters the annular groove 18 from the pressure relief hole 14, and is discharged from the through hole 19 to enter the next precision filter element for pressure relief.
