By above-mentioned setting, inner casing is connect respectively with dust catcher with outer casing screw, since dust catcher characteristic is Intermediate flow is larger, and two sides are thin, and collection section collects two sides air to collecting at center, is distributed as evenly as possible dust On filter membrane.

Further, the L-shaped clamping ring in cross section is provided on the inner wall of the inscribed section, the filtering base is placed in On the clamping ring.

By above-mentioned setting, filtering base is enabled to be put into inscribed intersegmental part, and increases the tortuous of its junction Increase air-tightness.

Further, setter plate is provided in the filtering base, the setter plate includes being arranged on the clamping ring In the support rod of crosswise, it is wholely set the concentric annular support board of multiple groups on the support rod, is set between adjacent support board It is equipped with gap.

By above-mentioned setting, while enabling air to pass through setter plate, filter membrane is enable to put in setter plate.

Further, filtering base inner wall is provided with annular groove above the support board, the filter membrane is fixedly installed on In the annular groove.

By above-mentioned setting, prevent filter membrane from falling off from filtering base in a ring groove so that filter membrane is capable of fixing.

Further, the filtering base and clamping ring abut against and are provided with sealing ring on the inner wall of one end, the sealing ring It is abutted with the clamping ring-side wall.

By above-mentioned setting, sealing ring lives the gap closing between filtering base and inner casing, prevent air from filtering base with Gap between inner casing is by influencing dust acquisition.

Further, the shell includes the linkage section and connecting section being wholely set, the linkage section and the connecting section It is threadedly coupled, in 90 degree of bendings, the connecting section and the inner casing, the filtering base are separate for the linkage section and the connecting section Dust catcher one end abuts.

By above-mentioned setting, shell resists filtering base, prevents filtering base from falling off outward.

Further, non-slip groove is provided on the linkage section outer wall.

By above-mentioned setting, increase the frictional force between testing staff's hand and shell, convenient for backing out shell.

Compared with prior art, the beneficial effects of the utility model are as follows:

(1) collection section being gradually increased by the way that radius is arranged, increases air inflow, in edge in intake process Dust along collection section inclined-plane gradually to drawing close, avoid the less situation of filter membrane upper edge powder；

(2) by setting setter plate, while fixed filter membrane, setter plate itself as less as possible is for air inflow It influences.
