Abstract
The utility model relates to a filtering cup mainly comprising a cup body which has a closed top and an open bottom. A convex liquid inlet and at least an air discharge hole are arranged at the top of the cup body is provided with, wherein the convex liquid inlet is communicated with the inner part of the cup body, and the area of the air discharge hole is larger than 3.14mm2; the air discharge hole comprises a central air discharge hole and outer ring air discharge holes which are arranged at the periphery of the central air discharge hole; the outer ring air discharge holes can be in fan shapes, circular-ring shapes or other shapes; a circular-arc shaped air discharge groove which is homocentric to the central air discharge hole is arranged at the top of the cup body; and the outer periphery of the circular arc is provided with a ring of circular-ring overflow prevention groove. The filtering cup is developed according to the design idea of humanized use, has simple structure, and has the following characteristics: 1. the air discharge is smooth, thereby effectively avoiding plugging of the air discharge hole caused by splash of filtering liquid and causing pressure relief of a filter; 2. the service life of an injection mold of the filter cup is improved and the graduations are clear; and 3. the liquid inlet is difficultly damaged, liquid enters smoothly by flowing down along the cup wall.
Description
Technical field
The utility model relates to a kind of filter cup, and particularly a kind of being applicable under positive pressure makes the enclosed filter cup of particle in the liquid or microorganism and fluid separation applications.
Background technology
The enclosed filter device that is used for liquid particle or microorganism and fluid separation applications mainly is made up of pipeline, transparent filter cup, base and the filter membrane that is fixed on the base, as shown in Figure 1.By the positive pressurization effect of peristaltic pump or Compressed Gas, realization liquid separates with particulate/microorganism.Be widely used in pharmaceuticals industry and laboratory at present, be mainly used in liquid degerming, remove the microorganism testing of particulate and based thin film filtration method.Yet, existing filter cup design is fairly simple, exist following shortcoming with not enough in production and processing and in using: 1, to design containing mark line in the filter cup inwall, when adopting Shooting Technique to produce, its injection mold is through production process such as formed product, the demoulding repeatedly, be very easy to be worn, cause the product capacity scale that is shaped smudgy, cause unstable product quality.Simultaneously, the graduation mark on inwall more is unfavorable for removing the filtered fluid residue on the filter cup inwall; 2, the inlet projection on filter cup top very easily is bruised at the top of cup, even fracture directly causes whole filter cup to scrap; 3, the inlet bottom does not have flow-guiding structure, cause easily liquid from the direct splash of inlet to filter membrane, and filter membrane is caused damage; 4 vent design are unreasonable, cause easily in the use and cause exhaust obstructed because of filtered fluid stops up.Particularly existing filter cup steam vent is less, causes in operations such as hand-held filter cup rock or because of feed liquor is too fast to make filtered fluid enter steam vent by liquid splash.In the time need carrying out safe exhaust by the air cleaner that is positioned at steam vent upper end, freely do not cause in the filter can't exhaust pressure relief because of exhaust for the filter internal gas pressure, and very easily causes pressure to continue to raise and influence the continuation use of filter.
The utility model content
The purpose of this utility model is to design a kind of exhaust that is easy to for the deficiency that solves above-mentioned technology, rational in infrastructure, and can improve injection moulding quality of production stability and filter cup.
In order to achieve the above object, the filter cup that the utility model is designed, the cup of its main top seal bottom opening constitutes, and is provided with the protruding inlet with the inner UNICOM of cup at the cup top, be provided with at least one steam vent at the top at cup, the area of this steam vent is greater than 3.14mm
2Described steam vent comprises a central row pore and is arranged on central row pore outer shroud steam vent on every side.Described outer shroud steam vent can be fan-shaped, annular or other shape.Be provided with the circular arc air discharge duct concentric at the cup top, be provided with a circle annulus anti-overflow groove in the periphery of circular arc with the central row pore.This structure Design characteristics are that steam vent is big, are difficult for being stopped up by liquid, are beneficial to pressure release in the cup.
Enter the damage of the direct splash in back in order to reduce filtered fluid from inlet, and reduce the probability that inlet is bruised, be provided with the inlet protective bulkhead of annular in protruding inlet periphery, be provided with flow-guiding structure at cup internal protrusion inlet end to filter membrane.Inlet protection wall energy protection inlet, the shock resistance of raising filter cup inlet, and flow-guiding structure can make the liquid that enters cup inside flow downward along wall of cup.
Can be provided with step-like graduation mark at the cup outer wall.This step-like graduation mark can make injection mold reach the purpose that long-time use is not worn, and more clear, improves the intensity of filter cup.
The resulting filter cup of the utility model, from the mentality of designing that hommization is used, rational in infrastructure, have following characteristics: 1, exhaust is smooth and easy, can prevent effectively that filtered fluid from splashing and cause that steam vent stops up on structure, makes the filter pressure release, and; 2, improve the service life of filter cup injection mold, graduation mark is more clear; 3, inlet cracky not, and feed liquor smoothness, dirty along wall of cup.

The specific embodiment
The utility model will be further described in conjunction with the accompanying drawings below by embodiment.
Embodiment 1:
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the filter cup that present embodiment is described, the cup 1 of its main top seal bottom opening constitutes, be provided with the protruding inlet 2 with cup 1 inner UNICOM at cup 1 top, be provided with a central row pore 9 and four fan-shaped outer shroud steam vents 3 at the top of cup 1.Wherein the diameter of central row pore 9 is 2mm.The radian of each outer shroud steam vent 3 is 60 °, and four outer shroud steam vents 3 are in the same circumference, forms a radian and be 240 ° steam vent group.Being provided with the circular arc air discharge duct 4 concentric with fan-shaped steam vent at cup 1 top, is that the periphery of circular arc air discharge duct 4 is provided with a circle annulus anti-overflow groove 5 in the periphery of fan-shaped big steam vent 3.Be provided with the inlet protective bulkhead 6 of annular in protruding inlet 2 peripheries, be provided with flow-guiding structure 8 at cup 1 internal protrusion inlet 2 ends.Described flow-guiding structure is inlet 2 pipe side wall upper sheds, is that the sidewall that filtered fluid flows to cup 1 also can be provided with step-like graduation mark 7 on cup 1 outer wall.
