Fine filter structure

Abstract

The fine filter structure has an extraction filter unit (3) with an upper frame main body (31) which has a hollow central portion and a coarse strainer (33) which is placed over an upper side of the upper frame main body. A stator (35) is provided with a lower end with a length of 2 centimeter. The strainer is provided with a channel. An upper end of the stator is formed with a through opening (353). Another extraction filter unit (4) is provided with a lower frame main body (41) with a hollow central section.

Description

technical field [0001] The invention relates to a filter structure, especially a filter structure applied in a brewing container and having two filter screens with different mesh numbers. Background technique [0002] According to research by Richard Wortman, a neuroendocrinologist at the Massachusetts Institute of Technology, and his colleagues, coffee can inhibit depressing brain chemicals, so it can achieve a refreshing and refreshing effect. Therefore, for For office workers who are busy with work, drinking coffee in moderation can make the mind more clear, make people think and concentrate, and then improve work efficiency. In addition, many medical journals pointed out that there are many ingredients in coffee that are beneficial to human health, such as caffeine, which can activate the central nervous system, resist drowsiness, reduce the chance of colds and colds, and slow down the occurrence of asthma and edema such as antioxidants, which can delay the progression ...

Problems solved by technology

[0006] However, as mentioned above, during the long-term research and development of the brewing container, the inventor found that the filter components used in the brewing container still have some shortcomings in the structure, causing trouble and inconvenience in subsequent use.

First, please refer to figure 1 As shown, when the user wants to drink coffee with a weaker taste and uses a filter screen 23 with a larger mesh number, a large amount of residue and coffee gelatin will be deposited on the filter screen 23, making the filter screen 23 The water permeability and gas permeability are greatly reduced, causing the liquid or air on the outer surface and the inner surface of the filter screen 23 to only flow through the path of the hollow cylinder 25 and the through hole 253, resulting in the liquid in the cup body 11 (i.e. Coffee) cannot flow out quickly, so that the user must wait for a long time to drink coffee

In addition, when the user wants to clean the filter assembly 2, the user usually puts his hand into the cup body 11 and holds the hollow cylinder 25 so that the filter assembly 2 can be pulled out of the cup body 11. But, because the fatty oil in the coffee still can be attached on this hollow cylinder 25, cause the surface of hollow cylinder 25 more slippery, and the length of this hollow cylinder 25 is comparatively short (about 0.5 centimeter), causes user's finger Only a small part can touch the hollow cylinder 25. Therefore, in the process of pulling out the filter assembly 2, the user often cannot easily take out the filter assembly 2 due to the small force application area of ​​the fingers, resulting in the user Difficulty with cleaning
