Description

Filter element and beverage filter containing the same

The new invention is a filter element composed of a ceramic or glass filter made of granular filter material and a beverage filter device containing the same. It is especially about a device that is easy to clean and does not require the use of consumables, and can be used for brewing coffee or tea at the same time. Class filter.

Due to the improvement of economic level, modern people are pursuing more taste of life. They usually drink coffee or tea to enjoy life after work and relieve the busy daily stress. The flavor and taste it exudes are particularly important, especially Making tea or coffee with your own hands is even better. Take hand-brewed coffee as an example. Today's hand-brewed coffee brewers mainly include three types: filtering with filter paper, filtering with metal mesh, or filtering with sintered ceramic particles. The brewing process of filtering with filter paper is as follows. The user will The filter cup is placed on the opening edge of the cup. The filter cup is funnel-shaped as a whole and has filter holes running through the bottom of the cup. A filter paper is placed on the filter cup. The shape of the filter paper corresponds to the shape of the inner wall of the filter cup. The user pours the coffee powder into it. Put it into the filter cup, then pour hot water into the hand brewing pot, the coffee flows out from the filter hole at the bottom through the filter paper, and the soaked coffee grounds remain on the filter paper to achieve the filtering effect; while the metal mesh is used to filter and sintered ceramic particles The brewing process is like filter paper, except that the filter paper and filter cup are replaced with metal mesh or sintered ceramic particles, which can also achieve the effect of filtering coffee powder.

However, in the above-mentioned process of filtering coffee powder with filter paper, because the filter paper is disposable, it is not environmentally friendly to throw it away after use, which will increase the cost of use for consumers, and the filter paper itself has an odor that easily affects the brewing process. The flavor of the drink usually needs to go through a rinsing process before brewing to reduce this interference factor, and the filter paper easily absorbs coffee oil esters, which will reduce the complete flavor of the coffee, and metal In the process of filtering coffee powder with a filter and sintered ceramic particles, because the pores of the metal filter and sintered ceramic particles are small, it is easy to cause powder residue and coffee grease to remain in the filter during repeated use, which affects the overall taste. and have a negative impact on the flavor. After drinking, you need to further clean the filter by inverting it, tapping it, and using tools to remove the coffee grounds. The overall process is time-consuming and labor-intensive. The sintered ceramic particle filter cup is also difficult to clean due to its overall thickness. Inside the filter layer; and the above devices usually do not have the function of making tea, and other utensils must be used. Therefore, the overall structure of the brewing device of the prior art has the above-mentioned problems and shortcomings, and it really needs to be improved.

In view of the shortcomings of the existing technology, the present invention provides a beverage filter that can be used for brewing tea or coffee at the same time. It is easy to clean and does not require the use of consumables.

Filtering is suitable for coffee, and soaking is suitable for tea or coffee. The filter-type brewing method can achieve vertical water flow, and the extraction is uniform and the taste is better. The immersion brewing method can use the insulation structure between the inner and outer cups to delay the cooling of the tea soup and increase the extraction rate. Ceramic or glass materials will not have any concerns about the dissolution of chemical substances and the impact of odor, and the filter 21 can retain a large amount of brewed coffee. Part of the oil ester increases the taste and aroma. The use of the water separator 40 can effectively avoid disturbing the coffee slurry and making it less likely to be stuffed with powder. It does not require the use of consumables. Compared with the existing technology, it saves costs and has environmental benefits. When cleaning coffee residues, the user only needs Hold the cylinder 22 and pull out the filter element 20 to remove most of the residue, which is highly convenient.

In the aforementioned process, since the filter disc 21 is made of ceramic or glass material sintered at high temperature, it has material stability, and uses a sheet-shaped structure that penetrates multiple filter holes with granular filter materials inside, so it has the advantage of being easy to clean and reusable.

In the aforementioned process, since the cylinder 22 of the filter element 20 has the ventilation hole 222 connected with the ventilation hole 212 of the filter plate, the filter element 20 can be prevented from floating due to the buoyancy of the gas during the brewing process.

During the aforementioned process, as shown in FIG. 6 , when the water distributor 40 is turned upside down and the water distributor tray 42 is placed on the inner opening 112 of the inner filter cup 10 , the heat preservation effect can be achieved.
