[0002] Currently, tea capsules are gaining popularity among consumers as a convenient way to drink tea. Users simply place the tea capsule into the matching tea brewing device to quickly obtain a cup of consistently high-quality tea. The process is simple and efficient, meeting the needs of modern people in their fast-paced lives for convenient tea drinking.

[0003] However, most existing tea capsules are single-use products. These single-use tea capsules are usually discarded after use, resulting in significant resource waste. Furthermore, their outer shells are often made of non-biodegradable materials such as plastic, requiring a long time to decompose in the natural environment, placing a heavy burden on the environment. With increasing environmental awareness and growing global emphasis on environmental protection, the contradiction between the use of traditional single-use tea capsules and the concept of sustainable development is becoming increasingly prominent. Therefore, this invention proposes a reusable, environmentally friendly tea capsule. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing disposable tea capsules are mostly made of non-degradable plastic and are directly discarded after use, causing resource waste and environmental pollution, which contradicts the concept of sustainable development.

[0036] Example

[0037] like Figure 1 and Figure 2 As shown, this utility model proposes a reusable and environmentally friendly tea capsule, including a shell 1. The shell 1, which occupies the largest volume of the tea capsule, is made of titanium alloy, exhibiting excellent fatigue resistance. The shell 1 is easy to reuse, reducing waste and protecting the environment compared to existing disposable products. Furthermore, titanium alloy has no metallic odor, does not react with the chemical components in tea, preserving the original flavor of the tea, and is harmless to the human body, making it suitable for sensitive individuals. A base 2 is installed at one end of the shell 1, and a shower head 3 is located at the end of the shell 1 away from the base 2. A pressure valve core 4 is installed in the base 2, which has a first space 41 and a second space 42. A valve bead 43 is located in the first space 41. When the valve bead 43 is in the first space 41, hot water is injected into the shell 1 to achieve pressurized brewing. Simultaneously, when the pressure exceeds a certain range, the valve bead 43 moves from the first space 41 into the second space 42, allowing the tea to be discharged. A support filter 5 is snapped onto the end of the base 2 near the shower head 3. The base 2, shower head 3, pressure valve core 4, and support filter 5 are all existing technologies and will not be described in detail here. The base 2 has perforations 21 corresponding to the positions of the first space 41 and the second space 42. This allows the valve bead 43 to be pushed back from the second space 42 into the first space 41 after each use by passing a small object through the perforations 21, facilitating the next pressurized brewing of the tea capsule and enabling reuse. Furthermore, the shower head 3, pressure valve core 4, and support filter 5 are all removable and can be replaced after reaching their maximum usage limit.

[0038] For details, please refer to Figure 2 and Figure 3 The aforementioned tea capsule includes a first sealing mechanism 6 disposed at the end of the base 2 away from the shower head 3, which seals the water outlet. The first sealing mechanism 6 includes a first fixed base 61 fixedly connected to the end of the base 2 away from the shower head 3, with the position of the first fixed base 61 fixed. A first cover membrane 62 is disposed on the side of the first fixed base 61 away from the base 2, which seals the water outlet of the tea capsule, isolating the tea leaves from the outside environment. A first pressure ring 63 is disposed on the side of the first cover membrane 62 away from the first fixed base 61, with a first threaded cylinder 64 fixedly connected to the outer ring of the first pressure ring 63. The first threaded cylinder 64 is threadedly connected to the first fixed base 61. When the first threaded cylinder 64 rotates, it is threaded onto the first fixed base 61, simultaneously causing the first pressure ring 63 to approach the first fixed base 61 and compress the first cover membrane 62, thus fixing the first cover membrane 62. A first silicone ring 65 is installed on the side of the first pressure ring 63 near the first fixed base 61. When the first pressure ring 63 approaches the first fixed base 61, it compresses the first silicone ring 65, improving the seal and isolating the tea leaves from the outside air. Meanwhile, the threaded connection between the first threaded cylinder 64 and the first fixed seat 61 facilitates disassembly and replacement of the first cover film 62 with through holes after use, enabling the reuse of tea capsules and reducing waste generation.

[0039] Furthermore, such as Figure 2 and Figure 4 As shown, the tea capsule also includes a filter assembly 7 installed on the end of the base 2 near the shower head 3. The filter assembly 7 is used to filter impurities in the tea water. The filter assembly 7 includes a filter membrane 71 disposed on the end of the base 2 near the shower head 3. The filter membrane 71 is used to filter impurities in the tea water. A second pressure ring 72 is disposed on the side of the filter membrane 71 away from the base 2. A second threaded cylinder 73 is fixedly connected to the outer ring of the second pressure ring 72. The second threaded cylinder 73 is threadedly connected to the base 2. After the second threaded cylinder 73 rotates, it is threaded onto the base 2, and at the same time, it drives the second pressure ring 72 to move closer to the base 2 and press the filter membrane 71, thereby fixing the position of the filter membrane 71. At the same time, the threaded connection between the second threaded cylinder 73 and the base 2 is also convenient for disassembly, making it easy to replace the filter membrane 71, ensuring the filtration effect of the filter membrane 71, realizing the reuse of the tea capsule, reducing waste generation, and responding to the concept of environmental protection.

[0040] For further details, please refer to Figure 1 , Figure 2 and Figure 5The aforementioned tea capsule also includes a second sealing mechanism 8 disposed at the end of the housing 1 near the shower head 3. The second sealing mechanism 8 is used to seal the water inlet. The second sealing mechanism 8 includes a second cover membrane 81 disposed on the side of the housing 1 away from the base 2. The second cover membrane 81 is used to seal the water inlet of the tea capsule, thus isolating the tea leaves from the outside environment. A third pressure ring 82 is disposed on the side of the second cover membrane 81 away from the housing 1. A third threaded cylinder 83 is fixedly connected to the outer ring of the third pressure ring 82. A second fixing seat 84 is threadedly connected to the inner side of the third threaded cylinder 83. The second fixing seat 84 is fixedly connected to one end of the housing 1 and has an L-shaped cross-section. After the third threaded cylinder 83 rotates, it is threadedly connected to the second fixing seat 84, which simultaneously drives the third pressure ring 82 to approach the housing 1 and squeeze the second cover membrane 81, thereby fixing the second cover membrane 81 and limiting the shower head 3 to prevent it from detaching. A second silicone ring 85 is installed on the side of the third pressure ring 82 near the housing 1. When the third pressure ring 82 is close to the housing 1, it squeezes the second silicone ring 85 to improve the sealing performance and isolate the tea leaves from the outside air. The second silicone ring 85 has a positioning groove 86 on the side near the housing 1 that corresponds to the second cover film 81. The positioning groove 86 is used to position the second cover film 81 before installation.

[0041] Both the first silicone ring 65 and the second silicone ring 85 are made of food-grade silicone, which is chemically stable and heat-resistant. They undergo high-temperature vulcanization during the production process and will not produce any odor when in contact with hot water, thus ensuring the quality of the tea soup.

[0042] In this embodiment, when the tea capsule is being brewed, the water outlet needle penetrates the first cover membrane 62, and the water inlet needle penetrates the second cover membrane 81. The water inlet needle discharges hot water into the housing 1, and the hot water is evenly distributed in the housing 1 through the shower head 3, contacting the tea leaves. As the amount of hot water increases, the valve bead 43 is blocked in the first space 41, causing the pressure in the housing 1 to increase, thus achieving pressurized brewing. After pressurized brewing is completed, if hot water continues to be injected into the housing 1, the pressure in the housing 1 becomes too high, thus forcing the valve bead 43 into the second space 42. At this time, the tea soup is drawn out through the water outlet needle.

[0043] After the tea capsules have finished brewing, remove the used tea capsules from the tea maker. Rotate the third threaded cylinder 83 away from the housing 1, then peel off and discard the second cover membrane 81, which has a through hole after being pierced by the water inlet needle. At the same time, remove the shower head 3. Then pour out the tea leaves from the housing 1 and rinse it briefly to remove any tea residue adhering to the housing 1. Next, rotate the second threaded cylinder 73 away from the base 2 and discard the filter membrane 71 with tea residue attached. Next, rotate the first threaded cylinder 64 away from the first fixed seat 61 and discard the first cover membrane 62, which has a through hole after being pierced by the water outlet needle. Shake off any remaining water on the housing 1, then use a small object to push the valve bead 43 back from the second space 42 into the first space 41 through the perforation 21.

[0044] A new first cover membrane 62 is placed inside the first threaded cylinder 64, and the first threaded cylinder 64 is rotated to connect its threads to the first fixed seat 61, while simultaneously squeezing the first silicone ring 65 to achieve a seal. A new filter membrane 71 is placed inside the second threaded cylinder 73, and the second threaded cylinder 73 is rotated to connect its threads to the base 2, while simultaneously squeezing the filter membrane 71 to fix it. Next, new tea leaves are placed into the housing 1, and the shower head 3 is placed on the housing 1. Finally, a new second cover membrane 81 is inserted into the positioning groove 86, and the third threaded cylinder 83 is rotated to connect its threads to the second fixed seat 84, squeezing and fixing the second cover membrane 81 to facilitate the next brewing. This also isolates the tea leaves from the outside environment before the next brewing, preventing excessive oxidation from air contact. Compared to existing technologies that discard the entire product after brewing, this solution only requires replacing the first cover membrane 62, filter membrane 71, and second cover membrane 81 after use, effectively reducing the waste rate.

[0045] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
