[0034] See also Fig. 9 , Figure 7 and Figure 5 Combined with Figure 4 , Figure 5 , Figure 6 and Figure 8 In the first aspect, the present application provides a barrier 5 for a drinking cup. When the drinking cup is used for making tea, the barrier 5 for the drinking cup is also called a tea strainer. Although the subsequent embodiments all take making tea as an example to illustrate the present application, the technicians can understand that the barrier for the drinking cup of the present application can be applied to application scenarios similar to making tea. The barrier 5 for a drinking cup includes a cavity 50. The cavity 50 includes a cavity side wall and a cavity bottom wall. The cavity side wall is provided with a plurality of side wall through holes 53, and the side wall through holes 53 connect the interior of the cavity 50 and the exterior of the barrier 5 for a drinking cup. The cavity bottom wall is provided with a plurality of bottom wall through holes 54. The plurality of bottom wall through holes 54 connect the interior of the cavity 50 and the exterior of the barrier 5 for a drinking cup.

[0035] As set up as above, since the cavity side wall of the cavity 50 is provided with a side wall through hole 53, and the cavity bottom wall of the cavity 50 is provided with a bottom wall through hole 54, after the drinking cup is covered with the barrier 5, when water is poured into the cup body 1 and the water level of the boiled water is lower than the side wall through hole 53, the boiled water flows into the cup body 1 from the bottom wall through hole 54, and the gas is discharged from the side wall through hole 53; when the water level of the boiled water gradually rises, the boiled water can not only flow into the cup body from the bottom wall through hole 54, but also a part of each side wall through hole 53 is for gas to flow out, and the other part is for boiled water to flow into the cup body. When the water level continues to rise, the side wall through hole 53 and the bottom wall through hole 54 are both for boiled water to flow into the cup body, thereby effectively preventing the problem of poor water discharge and overflow of boiled water, and boiled water can be quickly poured into the cup body 1.

[0036] See also Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 Combined with Figure 2 The side wall through hole 53 extends along the depth direction of the cavity 50 and is an elongated hole.

[0037] As described above, since the side wall through hole 53 is an elongated hole, the elongated hole has a large flow area. When the side wall through hole 53 is exhausted, the exhaust volume can be increased, which is convenient for gas discharge and further prevents boiling water from overflowing. The elongated hole has a large flow area and can increase the water output. The "elongated" shape can also play a filtering role. Finally, the side wall through hole 53 is an elongated hole that not only increases the water output but also effectively filters the tea residue. Of course, the large water output is conducive to the boiling water flowing into the cup body 1 and preventing the boiling water from overflowing. When pouring the water in the cup body 1, it is conducive to pouring out the water and can shorten the pouring time.

[0038] See also Fig.10 ,Will Fig.10 and Figure 7 The difference is only in the height of the handle 51. Specifically, the drinking cup barrier includes a handle 51 connected to the bottom wall of the cavity. The structure of the handle 51 is not limited, as long as the drinking cup barrier 5 can be taken out or put in. The height of the handle 51 relative to the bottom wall of the cavity is less than the depth of the cavity 50. In other embodiments, see Figure 7 , the height of the handle 51 may also be greater than the depth of the cavity 50 .

[0039] As configured above, if the drinking cup barrier 5 moves toward the cup cover 2 due to shaking or the like, the top of the handle 51 will not collide with the cup cover 2 because the height of the handle 51 is less than the depth of the cavity 50. Instead, only the edge of the drinking cup barrier 5 will collide with the cup cover 2, thereby preventing the cup cover 2 from being dented due to the aforementioned collision and ensuring the appearance of the cup cover 2.

[0040] See also Figure 6 , Figure 7 and Figure 8 Combined with Figure 2 , Figure 4 and Figure 5 In the second aspect, the present application provides a filter assembly. The filter assembly includes any of the aforementioned barrier members 5 for drinking cups and a filter member 4. The filter member 4 includes a accommodating chamber 40 and a filter hole connecting the interior of the accommodating chamber 40 and the exterior of the filter member. The shape of the filter hole is not limited, as long as it can achieve the filtering effect. In an embodiment of the present application, the accommodating chamber 40 includes a accommodating chamber side wall and an accommodating chamber bottom wall. The filter hole includes a side wall filter hole 401 provided on the side wall of the accommodating chamber and a bottom wall filter hole 402 provided on the bottom wall of the accommodating chamber. The barrier member 5 for drinking cups covers the accommodating chamber 40. There is no limit on how to cover it, as long as boiling water can flow from the barrier member 5 for drinking cups into the accommodating chamber 40. In some embodiments, the filter hole may not include the bottom wall filter hole 402, that is, the bottom wall of the accommodating chamber 40 is not provided with a filter hole.

[0041] Taking tea brewing as an example, the use of the above-mentioned filtering component is explained as follows:

[0042] Assembly of components: First, put tea leaves into the filter 4, then cover the drinking cup barrier 5 with the accommodating cavity 40, and fix the two. How the drinking cup barrier 5 is fixed to the filter 4 is not limited to the structure described later. Grasp the handle 51 of the drinking cup barrier 5, put the filter assembly into the cup body 1, and ensure that the filter assembly and the cup body 1 will not be loose. There is no limit to how the filter assembly and the cup body 1 will not be loose, for example, the filter assembly and the cup body 1 are abutted against the inner wall of the cup body 1 by the spring piece 52 on the drinking cup barrier 5.

[0043] Pour boiling water into the cup body 1: When boiling water is poured and the water level is lower than the side wall through hole 53, the boiling water flows into the accommodating chamber 40 from the bottom wall through hole 54, and then flows into the cup body 1 after passing through the accommodating chamber 40 (in the embodiment of the present application, it flows into the cup body 1 through the side wall filter hole 401 and the bottom wall filter hole 402). At this time, the gas in the cup body 1 is discharged from the side wall through hole 53 of the drinking cup barrier 5; when the water level of the boiling water gradually rises, the boiling water can not only flow into the cup body 1 from the bottom wall through hole 54, but also a part of each side wall through hole 53 is for gas to flow out, and the other part is for boiling water to flow into the cup body. When the water level continues to rise, the side wall through hole 53 and the bottom wall through hole 54 are both for boiling water to flow into the cup body 1.

[0044] The skilled person will appreciate that, although the use of the filter assembly is described above using brewing tea as an example, the filter assembly can be used in application scenarios similar to brewing tea.

[0045] See also Figure 6 , Figure 7 and Figure 8 Combined with Figure 2 , Figure 4 and Figure 5 In some embodiments, the sum of the total flow area of ​​the plurality of side wall through holes 53 and the total flow area of ​​the plurality of bottom wall through holes 54 is less than the total flow area of ​​the plurality of filter holes. In the case where the filter holes only include the side wall filter holes 401, the total flow area of ​​the filter holes refers to the total flow area of ​​the side wall filter holes. In the case where the filter holes include the side wall filter holes 401 and the bottom wall filter holes 402, the total flow area of ​​the filter holes is the sum of the total flow area of ​​the side wall filter holes 401 and the total flow area of ​​the bottom wall filter holes 402.

[0046] As described above, since the total flow area of ​​the plurality of side wall through holes 53 and the total flow area of ​​the plurality of bottom wall through holes 54 is smaller than the total flow area of ​​the plurality of filtering holes, it is ensured that the boiled water can flow into the cup body 1 in time to avoid overflow. When the water in the cup body 1 is poured out, it can also play a better filtering role.

[0047] An implementation method for realizing the above total area relationship is described as follows:

[0048] See also Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 Combined with Figure 4 , the plurality of side wall through holes 53 are evenly distributed on the side wall of the cavity and have equal flow areas. The even distribution refers to even distribution in the area where the side wall through holes 53 are arranged, for example Fig. 9 In the embodiment, because of the provision of the spring sheet 52, the side wall of the cavity is evenly divided into four areas, and the side wall through holes 53 of each area are evenly distributed, so that the intervals between the side wall through holes 53 of one area are equal to the intervals between the side wall through holes 53 of other areas; for another example, when there is no provision of the spring sheet 52 and other structures, the side wall through holes 53 are evenly distributed along the circumference. Regardless of the arrangement, the even distribution makes the flow rate of water flow or exhaust equal, so as to better exhaust and water flow out. Based on the above arrangement, the flow area of ​​a single side wall through hole 53 is controlled so that the total flow area of ​​the side wall through holes 53 is smaller than the flow area of ​​the side wall filter hole 401. In addition, in this embodiment, for the side wall filter hole 401, it can be evenly distributed or not.

[0049] The plurality of bottom wall through holes 54 are evenly distributed on the bottom wall of the cavity and have equal flow areas. The even distribution can also be understood with reference to the above description of the even distribution of the side wall through holes 53 .

[0050] As set up above, the aforementioned area relationship is achieved by evenly distributing the plurality of side wall through holes 53 with equal flow areas, and evenly distributing the bottom wall through holes 54 with equal flow areas. While meeting the demand for improving the filtering capacity, the filter element 4 has a simple structure and is easy to manufacture.

[0051] In some embodiments, see Figure 7 The accommodating cavity includes an accommodating cavity side wall, the filtering holes include a plurality of side wall filtering holes 401 disposed on the accommodating cavity side wall, and the total flow area of ​​the bottom wall through holes 54 is smaller than the total flow area of ​​the plurality of side wall filtering holes 401. A skilled person may understand that the flow area of ​​each bottom wall through hole 54 may be smaller than the flow area of ​​each side wall filtering hole 401, so that the total flow area satisfies the above relationship, and of course, the present invention is not limited thereto.

[0052] As described above, because the total flow area of ​​the bottom wall through holes 54 is smaller than the total flow area of ​​the plurality of side wall filter holes 401, even if the accommodating cavity 40 contains objects to be brewed (such as tea leaves), the boiling water can flow into the cup body 1 through the side wall filter holes 401 in time to avoid overflow due to poor water flow. Accordingly, when pouring out the water in the cup body 1, because the total flow area of ​​the bottom wall through holes 54 is small, it can play a better filtering role, and the taste of tea is better.

[0053] See also Figure 4 and Figure 7 Combined with Figure 6 and Figure 8 , the total flow area of ​​the multiple side wall filter holes 401 is greater than the total flow area of ​​the multiple bottom wall filter holes 402.

[0054] As described above, the total flow area of ​​the plurality of side wall filter holes 401 is greater than the total flow area of ​​the plurality of bottom wall filter holes 402. In the process of brewing a drink (such as tea), the residue produced by the drink (such as tea) is deposited on the bottom wall of the receiving cavity 40 of the filter element 4, effectively preventing too much residue from entering the water (such as tea) in the cup body 1. Of course, in the subsequent process of water flowing out from the side wall through hole 53, because there is less water, combined with the filtering effect of the drinking cup barrier 5, the taste is better (such as the taste of tea is better).

[0055] An implementation method for achieving that the total flow area of ​​the side wall filter holes 401 is greater than the total flow area of ​​the plurality of bottom wall filter holes 402 is as follows:

[0056] See also Figure 6 , Figure 7 and Figure 8The plurality of side wall filter holes 401 are evenly distributed on the side wall of the accommodating cavity and have equal flow areas. This even distribution can be understood by referring to the even distribution of the side wall through holes 53 mentioned above, and will not be described in detail. Based on the schematic diagram of the side wall filter holes 401, it can be understood that the plurality of bottom wall filter holes 402 are evenly distributed on the bottom wall of the accommodating cavity and have equal flow areas.

[0057] As configured above, since the plurality of side wall filter holes 401 are evenly distributed on the side wall of the accommodating chamber and have equal flow areas, and the plurality of bottom wall filter holes 402 are evenly distributed on the bottom wall of the accommodating chamber and have equal flow areas, the area relationship is ensured so that the slag is deposited on the bottom wall of the accommodating chamber 40, and the structure of the filter element 4 is simple and the manufacturing is simple.

[0058] See also Figure 6 and Figure 8 Combined with Figure 7 and Figure 2 The filter holes include a plurality of side wall filter holes 401 disposed on the side wall of the accommodating cavity 40. Along the depth direction of the accommodating cavity 40, the region where the plurality of side wall filter holes 401 are located includes a filter hole upper boundary 4011, the filter hole upper boundary 4011 is not higher than the cavity bottom wall, and there is no connecting hole penetrating the side wall of the accommodating cavity within the range between the filter hole upper boundary 4011 and the lower boundary of the plurality of side wall through holes, such as Figure 5 and Fig.10 As shown, there are no connected holes within the range of height D.

[0059] As configured above, since the upper boundary 4011 of the filter hole is not higher than the bottom wall of the cavity, and there is no connecting hole penetrating the side wall of the accommodating cavity within the range from the upper boundary 4011 of the filter hole to the lower boundary of the plurality of side wall through holes 53, it is ensured that the amount of water in the side wall filter hole is large, which is conducive to the flow of water into the cup body 1 and prevents water from overflowing.

[0060] Based on the above structure, taking tea making as an example, the method of using the drinking cup with the filter assembly is described to illustrate the beneficial effects of the above arrangement.

[0061] See also Figure 4 Combined with Figure 5 , Figure 6 and Figure 7As mentioned above, the tea leaves are located in the accommodating cavity 40. During the tea soaking process, most of the tea residues will be deposited on the bottom wall of the accommodating cavity of the filter element 4 (or the bottom cover 43). When the user drinks, the tea will flow out from the side wall through holes 53 and the bottom wall through holes 54. In the process of flowing out from the side wall through holes 53, it will be filtered by the side wall of the cavity where the side wall through holes 53 are set, and the filter element 4 will also filter the tea, thus performing double filtration. When flowing out from the bottom wall through holes 54, the bottom wall of the cavity where the bottom wall through holes 54 are set will filter the tea, and the filter element 4 will also filter the tea, thus performing double filtration. In summary, by providing the side wall through holes 53 and the bottom wall through holes 54 and combining the filter holes of the filter element 4, the taste of tea can be improved, and the user experience can be improved (for example, the tea is clearer and more refreshing, improving the tea drinking experience of the drinker).

[0062] See also Figure 7 , along the depth direction of the accommodating cavity 40, the area where the plurality of side wall filter holes 401 are located includes the filter hole lower boundary 4012. The height between the filter hole upper boundary 4011 and the cavity bottom wall is h, and the height between the filter hole lower boundary 4012 and the cavity bottom wall is H, and h / H≤1 / 5. In some embodiments, h=0, indicating that the via hole upper boundary 4011 is flush with the cavity bottom wall.

[0063] As set above, h / H≤1 / 5, the area corresponding to the side wall filter hole 401 is larger, and the water output is larger, thereby being able to promptly flow the boiling water from the bottom wall through hole 54 into the cup body 1 to avoid boiling water overflow.

[0064] See also Figure 7 The area between the lower boundary 4012 of the filter hole and the bottom wall of the accommodating cavity has no connecting hole penetrating the side wall of the accommodating cavity. Figure 7 There are no connected pores in the F region.

[0065] As configured above, since there is no connecting hole penetrating the side wall of the accommodating chamber in the area between the side wall filter hole 401 and the bottom wall of the accommodating chamber, tea leaves are more easily deposited on the bottom wall of the accommodating chamber and soaked in water, resulting in better tea brewing effect and better taste.

[0066] See also Figure 8 Combined with Figure 7 and Figure 5 The filter element 4 includes an assembly section 41, a middle section 42 and a bottom cover 43. The assembly section 41 and the middle section 42 are both through-shaped. The assembly section 41 and the bottom cover 43 are assembled at opposite ends of the middle section 42 to jointly enclose the accommodating cavity 40. The bottom cover 43 serves as the bottom wall of the accommodating cavity 40. The assembly section 41 is also assembled with the barrier element 5 for drinking cups, and an embodiment of how to assemble is described below.

[0067] As described above, since the filter element 4 includes the assembly section 41, the middle section 42 and the bottom cover 43, these three parts can be produced separately and then spliced ​​to form the filter element 4, which effectively improves production efficiency and reduces production costs.

[0068] See also Figure 8 and Fig. 9 The side wall of the accommodating cavity of the filter element 4 is provided with a spaced first turn button 511, and the barrier element 5 for drinking cup is provided with a spaced second turn button 512. The filter element 4 and the barrier element 5 for drinking cup are assembled by buckling the first turn button 511 and the corresponding second turn button 512. In the case where the filter element 4 is split into independent assembly sections 41, middle sections 42 and bottom cover 43, the first turn button 511 is provided on the assembly section 41. The technicians can understand that when the filter element 4 is a whole (that is, when it is not split into the assembly section 41, the middle section 42 and the bottom cover 43), the first turn button 511 and the second turn button 512 can also be buckled to complete the assembly.

[0069] As configured above, the filter 4 and the barrier 5 for the drinking cup are assembled through the first buckle 511 and the second buckle 512. The assembly is simple and reliable. The structure of the first buckle 511 and the structure of the second buckle 512 are simple, which is also conducive to easy manufacturing of the filter 4 and the barrier 5 for the drinking cup.

[0070] See also Figure 4 Combined with Figure 1 and Figure 2 In the third aspect, the present application provides a drinking cup. The drinking cup is not limited to a thermos cup, etc., and only needs to add hot water for brewing, such as making tea or coffee. The drinking cup includes a cup body 1 and any of the aforementioned filter components. The drinking cup barrier 5 covers the mouth of the cup body 1 (that is, the mouth of the drinking cup) and is spaced apart from the side wall of the cup body 1. The distance of the spacing is not limited, as long as water can flow out or gas can be discharged. The filter 4 is located in the cup body 1. On the other hand, the present application also provides a drinking cup. The drinking cup includes a cup body 1 and any of the aforementioned drinking cup barrier 5. That is, this drinking cup may not include the filter 4. The drinking cup barrier 5 covers the cup body 1, and this drinking cup can be used to make tea, coffee, etc.

[0071] As configured above, the drinking cup at least has the beneficial effects of the filtering assembly, which will not be described in detail.
