Description

[Technical Field]

[0001] The present invention is in the field of tea utensils and drinking implements, and more particularly relates to a drinking bottle with tea strainer. [Background technology]

[0002] Drinking tea is becoming more and more common in daily life. There are many ways to brew tea, including using special tea utensils. The inventors of the present invention noticed that these common tea brewing utensils are bulky and require many parts, making them inconvenient to carry when going out.

[0003] Existing portable bottles include a bottle body and a lid. The bottle has a through cavity, and the lid and bottle body are threaded together or removably connected by other mechanisms. A tea strainer is located inside the bottle body to contain tea leaves and separate them when pouring tea.

[0004] The inventor has discovered that with existing portable bottles (also known as water bottles), a vacuum layer forms at the top of the bottle during the process of extracting tea, causing a considerable amount of tea liquid to remain at the top of the bottle (between the lid and the tea strainer).If the user is unaware of this accumulated tea liquid, the accumulated tea liquid will immediately leak out as soon as the bottle is opened, sometimes resulting in burns to the user. Summary of the Invention [Problem to be solved by the invention]

[0005] In order to overcome the drawbacks of the above-mentioned conventional products, the present invention proposes a technical solution to optimize the structure of the drinking bottle with tea strainer and the function of the drinking bottle with tea strainer. [Means for solving the problem]

[0006] Some embodiments of the present invention provide a drinking bottle with tea infuser, which includes a lid, a connecting piece, a filter element (tea infuser), and an infusion reservoir.

[0007] the lid includes a first end and a first open end opposite the first end; the connecting component has a cavity, the cavity including a first connecting end and a second connecting end, the first connecting end being removably connected to the first open end; The tea strainer includes a first part and a second part which are fixedly connected or integrated, the first part faces the lid and is disposed at an end of the second part, the first part has an opening groove, the second part has a filter hole, the opening groove and the filter hole have different flow areas, and the filter element is removably connected to the connecting part; The extract storage portion is removably connected to the second connecting end of the connecting part.

[0008] In some embodiments, the shape of said open channel is selected from one or more of circular, U-shaped, rectangular, human-shaped, oblong, wavy, and polygonal channels.

[0009] In some embodiments, the flow area of ​​a single said open channel is greater than the flow area of ​​a single said filter hole.

[0010] In some embodiments, the outer wall of the first portion of the filter element is provided with a resilient clamping member.

[0011] In some embodiments, the resilient clamping member is configured as an arcuate protrusion.

[0012] In some embodiments, at least one open groove is disposed circumferentially around the first portion of the filter element.

[0013] In some embodiments, the diameter of the first portion of the filter element is greater than the diameter of the second portion of the filter element.

[0014] In some embodiments, the filter holes are arranged in multiple rows along the generatrix of the wall of the filter element.

[0015] In some embodiments, the lid comprises: Flip-open lid, and The flip-open lid includes a filter (mesh) attached to the bottom or inside of the lid.

[0016] In some embodiments, the connecting part is integrated with one of the lid and the extract storage part, and / or the extract storage part includes an outer shell and an inner liner fixed to the inside of the shell, and / or the first part and the second part of the filter element (tea strainer) are integrated or removably connected.

[0017] The drinking bottle with tea strainer provided by the above technical solution has a filter element (tea strainer) installed in the connecting part. The filter element (tea strainer) is divided into two parts, an upper part and a lower part, i.e., a first part and a second part. Both the first part and the second part have a structure that allows liquid or gas to circulate, and the first part has an open groove, and the second part has a filter hole.

[0018] The single flow area of ​​the open groove is much larger than the single flow area of ​​the filter hole. The single flow area of ​​the open groove is 1.5 to 100 times, preferably 3 to 80 times, and more preferably 5 to 60 times, the flow area of ​​a single filter hole. With this design, when liquid flows through the filter element (tea strainer), air flows from the extract storage area below the filter element through the open groove to the area above the filter element, allowing tea to flow smoothly from the drinking bottle lid through the filter element (tea strainer) to the extract storage area, solving the problem of tea residue in the drinking bottle lid cavity and preventing users from getting burned.

[0019] Without the above-mentioned opening groove, the vacuum layer formed in the upper area of ​​the tea strainer drinking bottle and the surface tension of water on the surface of the tea strainer holes make it difficult for liquid to pass through under the action of these two forces.To prevent the above-mentioned clogging without the above-mentioned opening groove, the tea strainer holes must be made with a larger diameter (usually 1-2 mm).This allows liquid to flow down through the tea strainer holes, while air flows from below the filter element (tea strainer) to the area above the filter element (tea strainer) through the filter element holes.

[0020] However, increasing the size of the holes in the filter element (tea strainer) can seriously affect the separation and filtering effect between the tea leaves and tea water, causing fine tea leaves to pass through the holes in the tea strainer. The technical solution proposed in this invention is designed with an open groove in the filter element (tea strainer), allowing the filter element to separate the air flow and the liquid flow inside the bottle. This technical solution eliminates the vacuum in the bottle's lid and connecting parts, allowing the filter holes in the side and bottom walls of the filter element to be designed with smaller pore sizes, for example, 0.2 to 0.8 mm in diameter. Furthermore, the problem of tea residue due to the formation of a vacuum layer is eliminated, improving the tea separation effect. The above-mentioned contradictions and problems can be effectively and completely resolved. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0022] The technical solutions provided by the present invention will be described in detail below in conjunction with Figures 1-18.

[0023] The inventor of the present invention discovered that in the existing portable bottles (also called water bottles), a vacuum layer is formed at the top of the bottle during the process of extracting tea, causing the tea liquid to remain at the top of the bottle. If a user opens the bottle without realizing that this remaining tea liquid remains, the tea will easily spill out, easily causing burns.

[0024] Specifically, when a tea strainer-equipped drinking bottle is assembled, the water and air inside the bottle are isolated from the outside world. The inventor noticed a problem that occurred during use of the bottle, where tea was blocked in the tea strainer filter at the top of the bottle. After extensive analysis and consideration, the inventor discovered that this problem occurred because, as water flows from the lid, i.e., from the top of the bottle through the filter element and into the extract storage section, a new space similar to a vacuum layer naturally forms at the top of the tea strainer-equipped drinking bottle (i.e., the lid of the bottle). This causes the air pressure inside the top of the bottle to become very low, preventing the liquid in the lid and connecting parts from flowing downward. Instead, the liquid remains within the lid and connecting parts, preventing the free flow of liquid and affecting the separation of the tea leaves and liquid. What's particularly serious is that if a user opens the bottle (water bottle) without realizing this, the liquid trapped between the lid and connecting parts or the filter may suddenly spill out, causing burns to the user. After repeated research and experiments, the inventors discovered that the liquid trapped in the bottle lid and filter element is caused by a vacuum formed in the upper part of the bottle or the lid. Therefore, the inventors of the present invention adopted a measure to design an opening groove at the top of the filter element to guide air flow, thereby reducing or avoiding the formation of the vacuum. The technical solutions provided by the embodiments of the present invention are described in detail below.

[0025] See Figures 1 to 16. Some embodiments of the present invention provide a drinking bottle with a tea strainer, including a lid 1, a connecting part 2, a filter element 3, and an extract storage part 4. The lid 1 is configured to be openable and closable, and the lid 1 and the connecting part 2 are removably connected. As shown in Figure 2, the lid 1 includes a first end 27 and a first open end 29 opposite the first end 27. As shown in Figure 5, the connecting part 2 includes a cavity 36 including a first connecting end 30 and a second connecting end 31, and the first connecting end 30 and the first open end 29 are removably connected. The extract storage part 4 is removably connected to the connecting part 2. The filter element 3 is disposed inside the connecting part 2 and is removably connected to the connecting part 2. As shown in Figure 9, the filter element 3 includes a first part 11 and a second part 12 that are fixedly connected or integrated with each other, and the first part 11 is disposed on the side of the second part 12 that faces the lid 1. The first part 11 has an open groove 13, and the second part 12 has a filter hole 15. The open groove 13 and the filter hole 15 have different flow areas.

[0026] In some embodiments, the single flow area of ​​the open groove 13 is greater than the single flow area of ​​the filter hole 15 .

[0027] As shown in FIGS. 7 and 8, in some embodiments, the extract reservoir 4 has an outer shell 9 and an inner liner 10 .

[0028] In some embodiments, the open groove 13 is configured in one of the following shapes: a circular groove, a U-shaped groove, a rectangular groove, a human-shaped groove, a rectangular groove, a wave-shaped groove, and a polygonal groove. The open groove 13 is configured as a circular groove, while the advantage of a U-shaped groove, a rectangular groove, and a chevron groove is that the groove has a large diameter and allows easy air circulation. Specific examples of polygonal grooves include an S-shaped, Y-shaped, and L-shaped groove.

[0029] In some embodiments, the open grooves 13 are configured with any combination of shapes, such as an inverted U-shaped groove and a wave-shaped groove at the same time.

[0030] In some embodiments, the outer wall of the filter element 3 is provided with a resilient clamp 14 disposed in the opening groove 13, and the edge of the resilient clamp 14 and the edge of the opening groove 13 are configured as a U-shaped groove or a rectangular groove. The edge of the filter element 3 is fixed to the silicone water seal packing 8 on the protrusion of the connecting part 2, and the filter element 3 is fixed to the silicone water seal packing 8 together with the resilient clamp 14, thereby preventing the filter element 3 from falling off even if the bottle is used upside down.

[0031] In some embodiments, the resilient clamp 14 is configured as a slit, at least one side of the resilient clamp 14 is connected to the filter element 3, and the central portion of the resilient clamp 14 is convex toward a position away from the center of the filter element 3. The resilient clamp 14 is an upright protrusion configured with an arc-shaped convex portion at its waist. The arc-shaped convex elastic force of the resilient clamp 14 is used to secure the filter element 3 to the silicone water seal packing 8. The silicone water seal packing has a certain elasticity to cooperate with the resilient clamp 14 and secure the filter element 3 in an appropriate position. The filter element 3 will not fall off on its own, but the filter element 3 is removable.

[0032] In some embodiments, the outer wall of the filter element 3 is provided with a resilient clamp 14, and the resilient clamp 14 and the open groove 13 are independent structures. The resilient clamp 14 is configured as a point, with its central portion convex toward a position away from the center of the filter element. The resilient clamp 14 is an upright convex configured with an arc-shaped convexity at its waist.

[0033] In some embodiments, one or more open grooves 13 are provided along the circumferential direction of the filter element 3. For example, three, four, or more than four open grooves 13 are provided along the circumferential direction of the filter element 3.

[0034] In some embodiments, one or more resilient clamps 14 are disposed along the circumference of the filter element 3. For example, 2 to 8 resilient clamps 14 are disposed along the circumference of the filter element 3, and more specifically, 2 to 4 resilient clamps 14 are more preferably disposed along the circumference of the filter element 3.

[0035] In some embodiments, the diameter of the first portion 11 of the filter element 3 is larger than the diameter of the second portion 12 of the filter element 3. The entire filter element 3 has a larger open top end and a smaller bottom end. That is, the second portion 12 is smaller in size. As a result, the smaller diameter at the bottom of the filter element 3 allows liquid to flow downward and pass through the filter holes 15 at a higher speed, thereby improving the separation efficiency of tea and water. The filter element 3 can also be structured into the first portion 11 and the second portion 12. This modular design of the filter assembly allows filter elements 3 with different diameters and shapes of filter holes 15 to be used as common parts, improving manufacturing efficiency and reducing material costs.

[0036] In some embodiments, the first portion 11 and the second portion 12 of the filter element 3 are of unitary construction.

[0037] In some embodiments, the first portion 11 and the second portion 12 of the filter element 3 are of a removable construction.

[0038] In some embodiments, the first part 11 of the filter element 3 and the connecting part 2 are manufactured in an integrated structure, and the second part 12 of the filter element 3 has a resilient clamp 14. The resilient clamp 14 is configured as a point-like protrusion, and the resilient clamp 14 is detachably connected to an opening groove 13 located on the outer wall of the first part 11. The above design avoids the trouble of the user having to open the lid 1 to install tea or other infusions, and the lid 1 and the connecting part 2 are made in an integrated structure, thereby reducing the number of parts in the entire drinking bottle with tea strainer.

[0039] In some embodiments, a fluid barrier 17 is provided inside the filter element 3. Specifically, it is provided as a step structure, for example. The function of the fluid barrier 17 is that when liquid flows along the step at the boundary between the first and second portions 11, 12 of the filter element, part of the flow hits the barrier 17, slowing the fluid velocity and generating vortices or bubbles. The formation of such vortices promotes air entrainment and helps the air circulate through the open grooves 13.

[0040] In some embodiments, the filter holes 15 are distributed over at least one wall of the filter element 3 .

[0041] In some embodiments, the filter holes 15 are distributed on the side walls and bottom wall of the filter element 3, and the diameter of the filter holes 15 located on the side walls is designed to be larger than the diameter of the filter holes 15 located on the bottom wall.

[0042] See Figure 2. Lid 1 can be made of glass or stainless steel. If lid 1 is made of a transparent material, the color of the liquid in the bottle can be seen through lid 1 to determine whether the required concentration is met. Lid 1 is provided with a lid thread 28 to facilitate removable connection with connecting part 2.

[0043] See Figures 3 to 5. In some embodiments, the connecting component 2 has a connecting component housing 5, a connecting portion inner embedded portion 6, and a connecting portion inner fitted component 7. The connecting component housing 5 is cylindrical and includes a hollow cavity and two upper and lower open ends. The connecting component housing 5 is located outside the connecting component 2, and the inner diameter of the connecting component housing 5 is larger than the connecting portion inner embedded portion 6 and the connecting portion inner fitted component 7. Therefore, the connecting portion inner embedded portion 6 and the connecting portion inner fitted component 7 can be attached and fixed inside the connecting component housing 5, and the connecting component 2 can be assembled.

[0044] See Figure 4. In some embodiments, the connection part inner embedded portion 6 is configured as a cylinder with a hollow cavity and two upper and lower open ends. The connection part inner embedded portion 6 is located at the center of the inside of the connection part 2, and the inner diameter of the connection part inner embedded portion 6 is larger than that of the connection part inner fitting part 7, so that the connection part inner fitting part 7 can be fixedly attached to the inside of the connection part inner embedded portion 6.

[0045] See FIG. 5 . In some embodiments, the connecting part 2 has a connecting-part inner-fitting part 7. The connecting-part inner-fitting part 7 includes a cavity 36, a first connecting end 30, a second connecting end 31, a first protrusion 32, and a second protrusion 33. The first connecting end 30 and the second connecting end 31 are configured as threads and are detachably connected to the lid 1 and the extract storage part 4, respectively. The first protrusion 32 and the second protrusion 33 are connected to a first recess 34 and a second recess 35 of the water seal gasket 8, respectively (see FIGS. 6 and 16 ), thereby fixing the water seal gasket 8 to the connecting-part inner-fitting part 7. The function of the first protrusion 32 and the second protrusion 33 is to fix the water seal gasket 8 to the connecting-part inner-fitting part 7 so that the water seal gasket 8 does not deform or fall off when the filter element 3 is attached, thereby improving the sealing effect of the water seal gasket 8.

[0046] See Figures 7 and 8. The extract storage portion 4 of the tea strainer drinking bottle comprises an outer shell 9 and an inner liner 10.

[0047] See Figure 10. In some embodiments, the filter holes 15 are arranged in multiple rows along the generatrix direction of the wall of the filter element 3. At least some of the filter holes 15 in each row have different sizes, or two rows of filter holes 15 have different filter hole sizes.

[0048] Some of the filter holes 15 in each row of filter holes 15 have different diameter sizes, which causes different surface tensions of the liquid flowing through the filter holes 15, making it difficult for a vacuum to form in the head space of the tea strainer drinking bottle. Reducing the formation of this vacuum layer reduces the possibility of the liquid being blocked and optimizes the usage performance of the tea strainer drinking bottle.

[0049] See Figure 11. In some embodiments, the filter holes 15 are arranged in multiple rows along the generatrix of the wall of the filter element 3. At least some of the filter holes 15 in each row have different shapes. The size of the filter holes 15 affects the air pressure balance and liquid flow rate at the top and bottom of the filter element 3. The size of the filter holes 15 must be set to a size that allows for air pressure balance. At the same time, the size of the filter holes 15 must be set to a size that prevents tea debris (whole tea leaves) from passing through.

[0050] The shapes of some of the filter holes 15 in each row of the filter holes 15 are different, and each shape has different characteristics, so the surface tension of the liquid flowing through these filter holes 15 is different, making it difficult for a vacuum to be generated in the upper space of the tea strainer drinking bottle, reducing the possibility of the liquid being clogged by the vacuum layer and optimizing the use performance of the tea strainer drinking bottle.

[0051] See Figure 12. In some embodiments, the filter holes 15 are arranged in multiple rows along the generatrix direction of the wall of the filter element 3, with the distance between two adjacent rows of filter holes 15 being different. Varying the spacing of the filter holes 15 arranged in a row reduces the possibility of a vacuum forming on the top of the drinking cup (lid).

[0052] See Figure 13. In some embodiments, the bottom wall of the filter element 3 is configured to protrude toward the bottom wall of the tea strainer drinking bottle. The shape of the bottom wall of the filter element 3 can also adopt a non-flat structure. The shape of the upper cavity of the tea strainer drinking bottle can be improved so that tea leaves gather at the bottom of the recessed part and liquid can easily flow through the filter holes 15 without clogging.

[0053] In each of the above-mentioned implementations, the depth of the recess in the filter element 3 is greater than 1 / 5 of the height of the tea strainer drinking bottle. This design ensures a sufficient depth for the filter element 3. The gas flow mainly passes through the upper half of the filter element 3, and the liquid flow mainly passes through the lower half of the filter element 3. Because the gas and liquid are separated, vacuums are less likely to occur, and the phenomenon of liquid not flowing properly at the bottom of the tea strainer drinking bottle is less likely to occur.

[0054] In some embodiments, the depth of the recess in the filter element 3 is 1 / 30 to 1 / 3 of the height of the drinking cup, preferably 1 / 25 to 1 / 3, more preferably 1 / 25 to 1 / 5, and even more preferably 1 / 20 to 1 / 5 of the height.

[0055] If the depth of the recess in the filter element 3 is shallower than 1 / 30 of the height of the tea strainer drinking bottle, the poured material such as solid tea will easily block the filter element 3, reducing the separation effect of the tea leaves and the liquid.

[0056] If the depth of the inner recess of the filter element 3 exceeds one-third of the height of the strainer bottle, the tea leaves and other extracting materials will always be submerged in the liquid, making it impossible to effectively separate the tea leaves from the liquid. In addition, the extract will become too concentrated, making the tea bitter.

[0057] See Figure 15. The open grooves 13 can also be configured as rectangular grooves, wavy grooves or polygonal grooves, the advantage of these shapes being that the filter element 3 can be lighter.

[0058] See Figure 16. In each of the above-described embodiments of the open grooves 13, in order for gas to effectively pass through the open grooves 13 and achieve gas equilibrium, when the filter element is assembled into the connecting part, the entire or partial flow surface of any one of the open grooves 13 extends beyond the bottom edge of the water seal packing 8, is exposed below the edge of the water seal packing 8, and faces the filter hole 15.

[0059] See Figure 16. In some embodiments of the first portion 11 of the filter element, the depth of the recess of the first portion 11 of the filter element is deeper than the depth of the water seal gasket 8. When the filter element 3 is attached to the water seal gasket 8, the protruding portion 16 of the first portion of the filter element is engaged with the upper notch of the water seal gasket 8, and a part of the first portion 11 of the filter element protrudes below the edge of the water seal gasket 8 and faces the filter hole 15.

[0060] Please refer to Figures 17 and 18. Another embodiment of the drinking bottle with tea strainer will be described below. Another embodiment of the present invention provides a bottle (water bottle) for integrating the functions of tea brewing and drinking. The bottle can be opened or closed with one hand, and when drinking with one hand, solid objects such as tea in the container will not enter the drinker's mouth along with the liquid. The drinking bottle with tea strainer includes a flip-open lid 18, a connecting part 2, a filter element 3, an extract storage part 4, and a filter (mesh) 19. The filter (mesh) 19 is attached to the bottom of the flip-open lid 18.

[0061] See Figure 18. The flip-open lid 18 is configured to be openable and closable. A user can drink the liquid in the tea strainer drinking bottle by opening the flip-open lid 18. In some embodiments, the flip-open lid 18 includes a filter (mesh) 19, a flip-open lid upper portion 20, a sealing stopper 21, an opening switch 22, and a flip-open lid lower portion 26.

[0062] The flip-open lid lower part 26 has a through-hole 25, and the upper half of the drinking portion 24 is inserted into and protrudes from the through-hole 25. The connection between the flip-open lid upper part 20 and the flip-open lid lower part 26 includes an internal elastic ring part 23 of the flip-open lid. A sealing stopper 21 is connected to the flip-open lid upper part 20. When the flip-open lid 18 is closed, the sealing stopper 21 blocks the through-hole 25 to prevent liquid from leaking. The inner edge of the through-hole 25 in the flip-open lid lower part 26 forms an annular inner recess, and the upper part of the filter (mesh) 19 is removably attached to the annular inner recess, sealingly connecting with the connecting part 2 and the flip-open lid 18. Using the above connection method, the flip-open lid 18 and the extract storage part 4 can be attached so as to be easily disassembled.

[0063] The extract storage unit 4 is used as a container for storing the extract and water. The outer shape of the extract storage unit 4 may be cylindrical, rectangular, hexagonal, octagonal, or any other shape, and is not limited to this. The top of the extract storage unit 4 is open, and the bottom is sealed. The top of the extract storage unit 4 is equipped with a connecting structure such as a thread, which seals the extract storage unit 4 to the connecting part 2, the lid 1, or the flip-open lid 18 to prevent leakage. The extract storage unit 4 has a storage cavity that can store water and tea leaves. Of course, tea leaves can be placed in the filter cavity 37, which will be described later, to facilitate the consumption of the extracted beverage, such as tea.

[0064] The filter cavity 37 is formed by the cooperation of the filter element 3 and the filter (mesh) 19. In some embodiments, the filter cavity 37 includes a top wall, a side wall, and a bottom wall. The filter element 3 functions as the bottom wall of the filter cavity 37, and the filter (mesh) 19 functions as the top wall of the filter cavity 37. The side wall of the filter cavity 37 can be formed by the combination of the filter element 3 and the filter (mesh) 19, or can be formed by the filter (mesh) 19 alone. In some embodiments, the filter cavity 37 can also be formed by the filter element 3 and the filter (mesh) 19 together with the inner wall of the upper opening of the extract storage section 4. Solids such as tea leaves or tea bags are placed in the filter cavity 37. The filter cavity 37 is configured to communicate with the extract storage section 4 through filter holes 15 provided in the wall of the filter cavity 37. Without the filter holes 15, the filter cavity 37 is sealed. In other words, except for the filter holes 15, no other parts of the filter cavity 37 are provided with openings. In this way, solid matter such as tea leaves remains within the filter cavity 37 unless a portion of the filter cavity is opened, otherwise the brewing solids would spill out of the filter cavity 37 upon tilting or inversion of the drinking cup.

[0065] As mentioned above, the filter cavity 37 is formed by using the filter element 3 and the filter (mesh) 19 together, and the filter cavity 37 is openable. Before making tea, solid matter such as tea leaves is first placed in the filter cavity 37, and then the filter cavity 37 is closed. Then, during the tea drinking process, the solid matter always remains in the filter cavity 37 and does not enter the extract storage section 4.

[0066] The drinking bottle with tea strainer provided by the above technical solution includes a filter element 3 and a filter 19, which together form a filter cavity 37. The filter cavity 37 functions to allow liquids to pass through while blocking solids such as tea. This design allows the drinking bottle with tea strainer to function as a teapot for brewing tea, a drinking bottle, and a multi-function device that prevents solids from entering the drinker's mouth during drinking, improving the usability of the drinking bottle with tea strainer. Furthermore, the drinking bottle with tea strainer provided by the above technical solution is suitable for making both hot and cold beverages. After adding solids such as tea, no other operations are required during drinking, making it particularly suitable for one-handed drinking.

[0067] In some embodiments, the filter element 3 has a separate structure. The filter element 3 is removably connected to at least one of the flip-open lid 18, the connecting part 2, the extract storage part 4, and the filter 19. In the above-described embodiments in which the filter element 3 is removably connected, the filter element 3 can be easily removed because the filter element 3 is removably connected, so that the filter bottom and the filter element 3 can be easily cleaned. In addition, the filter elements 3 with different functions and effects can be easily removed and replaced as needed by changing different filter hole sizes and filter depth specifications.

[0068] In some embodiments, the filter 19 is formed from a single structure and employs a separate structure that is removably connected to one of the flip-open lid 18, the connecting piece 2, the extract storage portion 4 and the filter element 3.

[0069] In other embodiments, the filter 19 is integrated directly into the flip-open lid 18 .

[0070] In an embodiment in which the filter 19 is removably connected to other components, the filter (mesh) 19 is removably connected, so that the filter 19 can be easily removed, facilitating cleaning of the inside of the flip-open lid 18 and the filter 19. Furthermore, the filter 19 can be easily replaced with one having different filter hole specifications as needed, thereby achieving a variety of functions and effects.

[0071] In the above technical solution, the filter element 3 and the filter 19 form a filter cavity 37, and the filter holes 15 of the filter cavity 37 have a filtering function. If necessary, the solids to be extracted or the solids already extracted, such as tea leaves, will remain in the filter cavity 37 without entering the extract storage section.

[0072] In some embodiments, both the filter element 3 and the filter 19 are provided with filter holes 15, which are configured to block solids and allow fluids to pass through. That is, by providing filter holes 15 on each wall of the filter cavity 37, the possibility of tea leaves clogging the filter holes 15 is reduced and fluids can pass through the filter holes 15 smoothly, improving drinking convenience.

[0073] The filter holes 15 of both the filter element 3 and the filter (mesh) 19 can adopt various structures. In some embodiments, the cross-sectional shape of the filter holes 15 includes at least one of a herringbone shape, a circle, a slit shape, and a rectangle. The so-called "person" shape refers to three slits with one end of the three slits converging. Herringbone-structured filter holes 15 allow fluid to easily pass through without adsorbing liquid, even if the filter holes 15 are small in size. Circular filter holes 15 are convenient for processing and manufacturing. Slit-shaped filter holes 15 are convenient for processing and manufacturing and have a high fluid passage rate. Rectangular filter holes 15 are convenient for processing and manufacturing.

[0074] The following is divided into several embodiments to explain the formation of the filter cavity 37. According to different installation and connection methods of the filter element 3 and the filter 19, the following methods exist. First, the filter element 3 and the filter 19 are removably attached together, and the entire assembly is attached to the flip-open lid 18. Second, the filter element 3 and the filter 19 are removably attached together, and the entire assembly is attached to the extract storage unit 4. Third, the filter element 3 and the filter 19 are removably attached together, and the entire assembly is integrally attached to the connecting part 2. Fourth, the filter element 3 and the extract storage unit 4 are attached together, and the filter 19 and the flip-open lid 18 are attached together. After the flip-open lid 18 and the connecting part 2 are attached together, the filter element 3 and the filter (mesh) 19 combine to form the filter cavity 37.

[0075] In the various embodiments described above, the filter element 3 and the filter 19 are detachably connected by threads, a snap structure, or the like. Both the filter element 3 and the filter 19 are configured concavely, with the depth of the filter element 3 being greater than the depth of the filter 19. The concave directions of the filter element 3 and the filter 19 may be the same or opposite. For example, the filter element 3 is concave toward the bottom of the extract storage section 4, and the filter 19 is concave toward the bottom of the extract storage section 4. This structure not only provides a relatively large space for placing solid objects but also makes installation easier. Alternatively, the filter element 3 is concave toward the bottom of the extract storage section 4, and the filter 19 is concave toward the flip-open lid 18. In this structure, the total depth of the filter cavity 37 is the sum of the depths of the filter element 3 and the filter 19, providing more space for storing solid objects. Alternatively, the filter element 3 is configured to be flat and the filter 19 is configured to be concave, with the filter element 3 being placed in the opening of the filter 19 .

[0076] It can be seen that by reasonably setting the positions of the male and female threads, a detachable and sealed connection can be achieved between the flip-open lid 18 and the connecting part 2 or the extract storage part 4. By appropriately setting the positions of the male and female threads, a detachable connection between the filter element 3 and the filter 19 can also be achieved.

[0077] In some embodiments, the connecting piece 2 and the lid 1 are an integral, unitary structure.

[0078] In some embodiments, the connecting piece 2 and the flip-open lid 18 are an integral, unitary structure.

[0079] In some embodiments, the connecting piece 2 and the extract storage portion 4 are an integral, unitary structure.

[0080] In some embodiments, the material of the filter element 3 is selected from one of stainless steel, plastic, glass, ceramic, and other metals.

[0081] In some embodiments, the material of the filter 19 is selected from one of stainless steel, plastic, glass, ceramic, and other metals.

[0082] In some embodiments, the material of the extract storage portion 4 is transparent.

[0083] In some embodiments, the material of the extract storage portion 4 is selected from one of stainless steel, plastic, glass, ceramic, silicon, and wood. In some embodiments, the wall of the extract storage section 4 is configured as a double-walled or multi-walled hollow.

[0084] In some embodiments, the volume of the extract storage unit 4 is between 150 ml and 1000 ml, preferably between 200 ml and 1000 ml, more preferably between 250 ml and 900 ml, and even more preferably between 300 ml and 800 ml.
