As a kind of preferred technical solution of the utility model, inner sleeve and outer sleeve are wine bottle arrangement, outer sleeve
The first half is threadedly attached in the first half of inner sleeve.
As a kind of preferred technical solution of the utility model, straight slot is located at the lower half of inner sleeve, and is set inside straight slot
It is equipped with Air Filter.
As a kind of preferred technical solution of the utility model, through-hole is located at the lower half of outer sleeve, described in two adjacent groups
Arc length between through-hole is more than the arc length of Air Filter.
As a kind of preferred technical solution of the utility model, restraining position ring block is arranged in the lower end outside of inner sleeve.
Compared with prior art, the utility model has the beneficial effects that：It is conveyed to inner sleeve by micropump and is detected area
The air in domain, by the dust that is filtered to remove of filter screen, gas is contacted with inductive probe, is detected, and it is accurate to improve detection
Degree, is discharged, when not used rotary sleeve cylinder by straight slot after detection, straight slot is staggered completely with through-hole, closing straight slot, in extraneous air
Dust and inductive probe separate, avoid the entrance of dust, convenient for preserving, improve service life.

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
Embodiment：
- 4 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of gas detecting instrument with dust filtering function,
Detection column 3 including detector ontology 1 and on detector ontology 1 further includes the micropump 2 for conveying air,
Inner sleeve 4 is provided on detection column 3, and inductive probe is located inside inner sleeve 4, is provided at the air inlet of micropump 2
The gas outlet of strainer 10, micropump 2 connects inner sleeve 4 by tracheae 7, and the sidewall spacers of inner sleeve 4 are provided with multiple straight slots, interior
The outside of sleeve 4 is socketed with outer sleeve 5, corresponded on the side wall of outer sleeve 5 straight slot on the inner sleeve 4 be provided with it is corresponding
Through-hole 9.
In the present embodiment, inner sleeve 4 and outer sleeve 5 are wine bottle arrangement, and the first half of outer sleeve 5 is threadedly attached in
The first half of inner sleeve 4.Straight slot is located at the lower half of inner sleeve 4, and straight slot is internally provided with Air Filter 8.Through-hole 9 is located at housing
The lower half of cylinder 5, the arc length between through-hole 9 described in two adjacent groups are more than the arc length of Air Filter 8.The effect of Air Filter 8 is to avoid
Dust in extraneous air enters the inside of inner sleeve 4 by straight slot.
Through-hole 9 is correspondingly formed access with straight slot, when detecting 2 output gas of micropump, is discharged by straight slot and through-hole 9,
