Lid is provided with the net structure II of hollow out ventilation, and box lid is internally provided with the internal thread being adapted with cassette holder external screw thread, cassette holder with
Box lid is threadedly coupled, and a circular hole I is provided with the filter pulp I, and filter pulp I is sleeved on the inside of cassette holder connector by circular hole I, filter pulp
I is arranged on cassette holder inner face, and the air guide separator is provided in the supporting item between filter pulp I and filter pulp II, and air guide separator is set
A circular hole II is equipped with, for air guide separator by being clamped on the inside of the circular hole II and connector, filter pulp II is arranged at air guide separator
Between box lid.
The cassette holder inner face is provided with radial supporting rib I, supporting rib I centered on circular hole I and protrudes from cassette holder
Face, is provided with a circle boss on the barrel of the connector inside cylindrical shape structure, and the boss and supporting rib I are highly consistent, filter
Cotton I is nested with boss by circular hole I, forms circulation cavity with cassette holder inner face, which is turned on by filter pulp I with connector.
The air guide separator is provided with the radial supporting rib II centered on circular hole II, supporting rib II and circular hole II
There are certain difference in height, air guide separator forms circulation cavity respectively with filter pulp I and filter pulp II, which leads with connector
It is logical.
The box lid inner face is provided with circular support structure, and there are certain difference in height, filter pulp with box lid inner face for the structure
II forms circulation cavity with box lid inner face, which is turned on by filter pulp II with connector.
The cassette holder, box lid, filter pulp I, filter pulp II and air guide separator are circle.
The present invention realizes double-entry by the net structure that the hollow out on cassette holder and box lid is ventilated, and increases filtering surface
Product, reduces volume；Pass through the filter pulp I between cassette holder and air guide separator, and the filter pulp between box lid and air guide separator
II realizes two-sided filtering, and gas permeability improves；It ensure that the air after filtering passes through company by each cavity by the design of connector
Fitting sucks human body, by setting supporting rib and circular support structure, forms circulation cavity, realizes preferably ventilative.
