Specific embodiment
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
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of injecting type filter, including upper cover 1 is under
Lid 2, the upper cover 1 and lower cover 2 are connected through a screw thread, and the upper cover 1 and 2 outside of lower cover have been connected through a screw thread connector sleeve 3.
The 2 upper end activity of lower cover is plugged with upper cover 1, and 1 lateral wall of upper cover and 2 inner sidewall of lower cover are equipped with screw thread.Under the upper cover 1
The first gasket 12 is equipped between 2 upper surface of end face and lower cover.First gasket, 12 quantity is no less than 2, in upper cover 1
It is equipped with the first gasket 12 with 2 contact position of lower cover, the gasket is rubber gasket and a kind of self-expanding gasket
There is piece certain flexibility can squeeze it during upper cover 1 and lower cover 2 are connected through a screw thread, and fix it more
Firm, sealing effect is more preferable.1 upper surface middle part of upper cover is provided with limit card slot 4,4 lower surface of limit card slot be provided with into
Liquid mouth 5,1 lower surface of the upper cover middle part are provided with the first cone tank 6, and the 6 side wall lower ends portion of the first cone tank is provided with the second card
Slot 8, the 1 lateral wall lower end of upper cover are provided with the first card slot 7, and 2 upper surface middle part of lower cover is provided with the second cone tank 10, described
First cone tank 6 and the second cone tank 10 are equal in magnitude, and the first cone tank 6 and the second about 10 cone tank are symmetrically.Sample
Product liquid by inlet 5 after being entered, and under the effect of the first cone tank 6, liquid is dispersed sprinkling downwards, can be effectively reduced
The impact forces of sample solution.Under the effect of the second cone tank 10, the liquid being sprayed on filter membrane can be made to drop downward into out
In liquid mouth 14, the residual of sample solution is avoided, causes to waste.Second cone tank, the 10 sidewall upper portion is provided with third card slot 9,
Liquid outlet 14 is equipped in the middle part of 2 lower end surface of lower cover.Filter membrane is connected in 9 slot of second card slot 8 and third card slot

10 and liquid outlet 14 be sequentially communicated.Second card slot 8 and the installation symmetrical above and below of third card slot 9, by the way that filter membrane 11 is caught in
, can be accurately fixed to filter membrane 11 in upper cover 1 and the interconnection extrusion process of lower cover 2 in two draw-in groove 8 and third card slot 9,
By mutually dismantling upper cover 1 and lower cover 2, also facilitates the cleaning and replacement to filter membrane 11, avoid to entire injecting type filter
It is replaced, to cause waste for no reason.Pass through setting inlet 5, liquid outlet 14, the first cone tank 6 and the second cone tank
Liquid in inlet 5 can be uniformly sprayed on filter by the effect of the first cone tank 6 and the second cone tank 10 by 10 structures
On film 11, to avoid the filter membrane of filter directly facing the impact of sample solution, so that the anti-pressure ability of filter membrane is poor, cause
The case where filter membrane service life reduces.The injecting type filter, by the way that the first gasket 12, the second card slot 8, third is arranged
3 structure of card slot 9, the second gasket 13 and connector sleeve can be by filter membrane 11 tightly by being press-connected to upper cover 1 and lower cover 2
It is caught in 9 slot of the second card slot 8 and third card slot, it, can in the effect of the first gasket 12, the second gasket 13 and connector sleeve 3
The phenomenon that effectively avoiding injecting type filter leakage improves seal degree between filter membrane 11 and upper cover 1, lower cover 2, meanwhile, pass through
Quickly upper cover 1 and lower cover 2 are dismantled, easily filter membrane 11 can be cleaned, it is molten to reduce the remaining sample of filter interior
Liquid and impurity achieve the effect that improve filter effect.
Working principle: when using injecting type filter to sample filtering, liquid flows into the first taper by inlet 5
Slot 6 is become by slot and is flared, liquid is uniformly sprayed to 11 outer end of filter membrane, after the filtering by filter membrane 11, passes through going out for lower end
Liquid mouth 14 flow out, in use, if the remaining sample impurity accumulated on filter membrane 11, can by by upper cover 1 under
The disassembly of lid 2 is cleaned.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
