Threaded filter cup convenient to clean

Technical Field

The utility model relates to an experimental apparatus technical field especially relates to a screw thread filter bowl convenient to wash.

Background

In biological experiments, the experimental materials are often required to be filtered to obtain required experimental raw materials, and the filter paper is placed in a funnel for filtering in the conventional filtering mode. Chinese patent with publication number CN205307917U discloses a filter cup leaks for laboratory, including being the cup that leaks hopper-shaped, the upper portion of cup is for holding the liquid fill, the lower part of cup is the drain pipe, can dismantle in holding the liquid fill and be connected with the ceramic filter of rather than looks adaptation, just the ceramic filter with the inner wall that holds the liquid fill is sealing connection when the cooperation.

The filter bowl adopting the above technical solutions and the prior art solutions also has the following disadvantages: on one hand, the inner wall of the filter bowl needs to be carefully cleaned after each filtration to prevent the experimental materials polluting the next experiment, but the attachments with strong viscosity on the bowl wall are hard to clean after being dried, so that the energy and time of experimenters are wasted; on the other hand, the filter cup in the center of the prior art generally needs a drainage rod to conduct drainage when filtering, and prevents filtrate from flowing into the filter cup too quickly. There is therefore a need for a threaded bowl that is easy to clean to solve the above problems.

Disclosure of Invention

The utility model aims at overcoming the problems of the prior art and providing a thread filter cup convenient to clean.

In order to achieve the above purpose, the utility model adopts the following scheme:

the utility model provides a screw thread filter cup convenient to wash, includes round platform shape cup, and the cup bottom is equipped with the liquid outlet that is used for fixed filter membrane, and the inner wall from the top down of cup is equipped with the drainage screw thread that is used for guiding liquid, and accessible drainage screw thread falls into the cup bottom gently along the inner wall spiral gliding of cup after liquid gets into from the rim of a cup of cup upper end. The experimental operation of experimenters is facilitated, and the experimental efficiency is improved. Meanwhile, when the filter cup is cleaned, water flow can automatically wash the inner wall of the filter cup by means of the drainage threads, and the operation is simple, so that the experiment efficiency of experimenters is further improved.

Furthermore, an arc-shaped chamfer convenient for the liquid to slide off the liquid outlet is arranged around the bottom of the cup body. This arc chamfer can prevent effectively that the hydrops from appearing in the filter bowl bottom, reduces the loss of experiment raw materials and also makes it easily wash.

Further, the cross section of the drainage thread is trapezoidal. The automatic washing of rivers to the filter bowl inner wall is convenient for, further improves the cleaning efficiency.

Furthermore, the included angle formed by the upper surface of the drainage thread and the bottom of the cup body is theta, wherein theta is more than 0 degree and less than or equal to 90 degrees.

Furthermore, the upper surface of the drainage thread is vertical to the inner wall of the cup body. The solution can smoothly fall into the bottom of the filter cup through the drainage thread, so that the inner wall of the filter cup can be automatically washed by water flow, and the cleaning efficiency is further improved.

Furthermore, the lower end of the cup body is integrally formed with an annular base. The threaded filter bowl can be sleeved into a reagent bottle through the annular base, so that the solution can be conveniently collected.

Furthermore, the cup body and the drainage thread are both made of high-transparency polystyrene. The cup body with high transparency can facilitate the experimenter to observe the internal condition of the threaded filter cup and is convenient to check whether the threaded filter cup is washed clean or not.

Further, the cup body and the drainage thread are integrally formed.

Compared with the prior art, the utility model has the advantages of as follows: the drainage screw thread is integrally formed on the inner wall of the threaded filter cup, the drainage screw thread can smoothly fall into the bottom of the filter cup without a drainage rod, the experimental operation of experimenters is facilitated, and the experimental efficiency is improved. Meanwhile, when the filter cup is cleaned, water flow can automatically wash the inner wall of the filter cup by means of the drainage threads, and the operation is simple, so that the experiment efficiency of experimenters is further improved.
