Description

Tea leaf filter cup and tea set capable of limiting flow

Technical Field

The utility model relates to a filter bowl, especially a tealeaves filter bowl of restriction flow still relate to this tea set.

Background

Hand coffee is the most popular way of brewing coffee in the fine coffee age today. The common hand coffee making process is as follows: 1. firstly, folding filter paper, wherein the filter paper is usually in a fan shape, is folded into a funnel shape and is attached to the wall of a filter cup, and then is placed into the filter cup; 2. weighing coffee beans as required, grinding the coffee beans into powder, and pouring the coffee powder into a filter hopper to be paved; 3. uniformly injecting water into the filter cup for braising, continuously injecting water after braising expansion, and allowing the filtered coffee to enter a coffee pot from the lower part of the filter cup to finish the extraction process; 4. and finally, pouring the coffee in the coffee pot into a cup for drinking. In addition, in order to make coffee more conveniently by hand, various improvements are made to coffee makers and coffee cups to meet outdoor or other needs.

At present, a plurality of young people brew the tea by using the coffee filter cups with hands and a brewing method, so that the tea is more convenient, quicker, more fashionable and modern. However, the key problems exist in that the hand-made coffee filter cup is designed for coffee powder, no flow limiting hole is needed, and the hole diameter of the hole is not accurate. When the tea making device is used for making tea, the tea flows into the cup when the tea leaves are not fully soaked due to too fast water flow speed, the tea soup is light, or the flow speed of the water poured into the filter cup from the water boiling kettle is controlled with great effort, so that people are tired, and the tea making device is not suitable for people to use.

Based on the above, if an accurate flow limiting hole is added at the bottom of the funnel, people can quickly fill boiled water in the filter cup at one time, so that tea soup in the filter cup flows into the filter cup at a certain speed, and therefore the time and labor are saved, and a cup of uniform and stable tea soup can be quickly drunk.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention, and it is obvious that the described embodiments are only some examples of the present invention, and not all examples. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

Example 1

As shown in fig. 2, in the tea leaf filter cup with flow restriction of this embodiment, a flow restriction hole 1.6 is formed in the bottom of a cup body 1.2 of the tea leaf filter cup, the sectional area of the flow restriction hole is 4.9mm, and the diameter of the circular hole is 2.5 mm. The volume of the filter bowl was 150ml, as shown in FIG. 3.

As shown in fig. 1, the tea set with a flow limiting function of the present embodiment includes the above-mentioned tea leaf filter cup 1, a filter screen 2 without filter paper disposed in the tea leaf filter cup 1, and a tea pot 3 disposed at the bottom of the tea leaf filter cup 1, wherein the tea pot 3 is a glass pot. The tea filter cup 1 comprises a conical cup body 1.2, an outer edge 1.1 of the 1.2 opening of the conical cup body is arranged, a bearing part 1.4 around the bottom of the cup body 1.2 is arranged, and a ring body 1.5 arranged at the lower end of the bearing part 1.4 along a flow limiting hole is arranged.

As shown in figure 4, the filter screen 2 without filter paper is matched with the tea leaf filter cup in shape, the meshes 2.2 are distributed on the side face 2.3 of the screen body, the outer edge 2.1 is arranged at the opening of the filter screen 2, and the outer edge 2.1 can be erected on the outer edge 1.1 of the cup body 1.2, so that the tea leaf filter cup is convenient to take. The material of the filter screen can be the existing food-grade stainless steel, ceramics, glass, plastic, copper, tin, silver or gold.

The flow rate has a significant effect on the palatability of the tea soup and therefore it is important to estimate the flow rate of the tea soup to determine the capacity of the bowl and the cross-sectional area (pore size) of the restricted orifice in hand-brewing tea. Since the tea soup flow rate does not need to be particularly accurate, an estimation method can be adopted.

The flow rate measurement formula of this embodiment: the average flow velocity (v) is the volume flow (Q)/restriction orifice cross-sectional area (a).

Based on the above formula, the method for determining parameters of the tea leaf filter cup according to the embodiment includes the following steps:

blocking a restricted flow hole of a filter bowl, filling the filter bowl with water, then putting the water in the filter bowl, and measuring time t;

step (2), weighing the discharged water to obtain the volume V of the water;

and (3) estimating the flow rate of the flow limiting hole according to the formula V = V/t.

And (4) measuring the sectional area A of the flow limiting hole to ensure that the volume flow Q is equal to the flow speed v × sectional area A, and selecting filter cups with different flow limiting hole areas and volumes according to different teas.

The flow rate has a great relationship with the palatability of tea soup and the patience for people to wait. The humanized selection is to consider the palatability of the tea soup and shorten the brewing time as much as possible.

The method of use of this example is as follows:

according to the required tea amount and the tea soaking time, a certain amount of tea is put into a filter screen, and hot water with a certain temperature is added. The flow rate of the tea soup is limited by the flow limiting hole, so that when the tea soup filtering device is used, boiled water is poured into the filtering cup and slowly flows down, and no skill or extra action is needed. The flowing tea soup can be drunk, and filter cups with different volumes and flow-limiting holes can be selected according to the taste.
