Description

[Technical field]

[0001] The present invention is in the field of tea ware 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 inventor 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] An existing portable bottle includes a bottle body and a lid. The bottle has a through cavity, and the bottle lid and the bottle body are threadedly engaged or removably connected by other structure. A tea strainer is disposed inside the bottle body to contain tea leaves and separate the tea leaves when brewing tea.

[0004] The inventor has discovered that with 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 a significant amount of tea liquid to remain at the top of the bottle (between the lid and the tea strainer). Sometimes, when a user opens the bottle without realizing that this accumulated tea liquid is present, the accumulated tea liquid immediately leaks out, causing burns to the user. Summary of the Invention [Problem to be solved by the invention]

[0005] In order to overcome the shortcomings 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 optimize 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 piece has a cavity, the cavity including a first connecting end and a second connecting end, the first connecting end being releasably 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 a circular, U-shaped, rectangular, human-shaped, oblong, wavy, and polygonal channel.

[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, an 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 of the open grooves is disposed circumferentially around the first portion of the filter element.

[0013] In some embodiments, a diameter of the first portion of the filter element is larger than a 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 secured to the inside of the shell, and / or the first and second parts of the filter element 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, that is, it is composed of 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, the first part has an opening 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 1.5-100 times, preferably 3-80 times, more preferably 5-60 times, of the flow area of ​​the single filter hole. With this design, when the liquid flows through the filter element (tea strainer), the air flows from the extract storage part below the filter element through the open groove to the area above the filter element, and the tea flows smoothly from the lid of the drinking bottle through the filter element (tea strainer) to the extract storage part, solving the problem of tea remaining in the lid cavity of the drinking bottle and avoiding the problem of users being burned.

[0019] Without the above opening groove, due to the vacuum layer formed in the upper area of ​​the tea strainer drinking bottle and the surface tension of the water on the surface of the tea strainer hole, the liquid is difficult to pass through under the action of these two forces. In order to prevent the above clogging of the liquid without the above opening groove, it is necessary to provide a tea strainer hole with a larger diameter (usually 1-2 mm). This allows the liquid to flow down through the tea strainer hole, while at the same time air flows through the filter element hole from below the filter element to the area above the filter element.

[0020] However, if the size of the holes in the filter element (tea strainer) becomes large, it will seriously affect the effect of separating and filtering the tea leaves and tea water, and fine tea leaves will pass through the holes in the tea strainer. The technical solution proposed in the present invention has an open groove designed in the filter element (tea strainer), so that the filter element has the function of separating the air flow and the liquid flow in the bottle. From the above technical solution, the lid part and the connecting part of the bottle are not vacuumed, and the filter holes in the side wall and the bottom wall of the filter element can be designed to have a smaller hole diameter, for example, a hole diameter of 0.2 to 0.8 mm. In addition, the problem of tea residue caused by the formation of a vacuum layer is eliminated, and the tea separation effect can be improved. The above-mentioned contradictions and problems can be effectively and completely solved. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] The technical solutions provided by the present invention are described in detail below in conjunction with FIGS.

[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, and the tea liquid remains at the top of the bottle. If a user opens the bottle without knowing that the tea liquid remains, the tea will easily spill out and cause burns.

[0024] Specifically, when the drinking bottle with tea strainer is assembled, the water and air in the bottle are isolated from the outside world. The inventor noticed that the problem of tea being blocked in the tea strainer filter at the top of the bottle occurs during use of the bottle. The inventor analyzed and thought deeply and found that the reason this problem occurs is that when water flows from the lid, i.e., from the top of the bottle through the filter element to the extract storage section, the water flows under the action of gravity, and at the same time, a new space similar to a vacuum layer is naturally generated at the top of the drinking bottle with tea strainer (i.e., the lid of the bottle). Therefore, the air pressure in the top of the bottle becomes very low, and the liquid in the lid and the connecting parts does not flow downward, but remains in the lid and the connecting parts, preventing the free flow of the liquid, which also affects the separation of the tea leaves and the liquid. What is particularly serious is that if a user opens the bottle (water bottle) without knowing the above condition, the liquid that has remained between the lid and the connecting parts or the filter will suddenly spill out, causing burns to the user. Through repeated research and experimentation, the inventors have found that the liquid trapped in the bottle cap and filter element is caused by the vacuum formed in the upper part of the bottle or the cap. Therefore, the inventors of the present invention adopt a measure to design an opening groove at the top of the filter element to guide the air flow, thereby reducing or avoiding the formation of the above-mentioned vacuum. The technical solutions provided by the embodiments of the present invention are described in detail below.

[0025] Please refer to Figures 1 to 16. Some embodiments of the present invention provide a drinking bottle with 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 to the first end 27. 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, as shown in Figure 5. 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, and the first part 11 is disposed on the side of the second part 12 facing the lid 1. The first part 11 is provided with an opening groove 13, and the second part 12 is provided with a filter hole 15. The flow area of ​​the open groove 13 and the flow area of ​​the filter hole 15 are different from each other.

[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 storage portion 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, which are a circular groove, a U-shaped groove, a rectangular groove, a human-shaped groove, a rectangular groove, a wavy groove, and a polygonal groove. The open groove 13 is configured as a circular groove, and the advantage of the U-shaped groove, the rectangular groove, and the angle-shaped groove is that the diameter of the groove is large, and air is easy to circulate. The polygonal groove is specifically, for example, an S-shaped, a Y-shaped, an L-shaped, etc.

[0029] In some embodiments, the open grooves 13 are configured with any combination of shapes, such as inverted U-shaped grooves and wavy grooves 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 with a U-shaped groove or a rectangular groove. The edge of the filter element 3 is fixed to the silicone water seal packing 8 of 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 elastic clamp 14 is configured as a slit shape, at least one side of the elastic clamp 14 is connected to the filter element 3, and the central part of the elastic clamp 14 is convex toward a position away from the center of the filter element 3. The elastic clamp 14 is an upright protrusion configured to have an arc-shaped convex part at the waist. The arc-shaped convex elastic force of the elastic clamp 14 is used to fix the filter element 3 to the silicon water seal packing 8. In addition, the silicon water seal packing has a certain elasticity to cooperate with the elastic clamp 14 and fix the filter element 3 in an appropriate position. The filter element 3 will not fall off naturally, 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 shape, and its central portion is convex toward a position away from the center of the filter element. The resilient clamp 14 is an upright convex configured to have 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 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 large open top end and a small bottom end. That is, the size of the second portion 12 is small. As a result, the diameter of the lower portion of the filter element 3 is small, so that the liquid flows downward and passes through the filter holes 15 at a higher speed, thereby improving the separation efficiency of tea and water. The structure of the filter element 3 can also be divided 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, which improves manufacturing efficiency and reduces 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 an elastic clamp 14. The elastic clamp 14 is configured as a point-like protrusion, and the elastic clamp 14 and the opening groove 13 located on the outer wall of the first part 11 are removably connected. The above design allows users to avoid the trouble of having to open the lid 1 to install tea or other infusions, and the lid 1 and the connecting part 2 can be made into an integrated structure to reduce the number of parts of the entire drinking bottle with tea strainer.

[0039] In some embodiments, a fluid barrier 17 is provided inside the filter element 3. Specifically, for example, it is provided as a step structure. The function of the fluid barrier 17 is that when a liquid flows along the step at the boundary between the first part 11 and the second part 12 of the filter element, a part of the flow hits the barrier 17, and the fluid speed is reduced, generating vortices and air bubbles. The formation of this kind of vortex promotes the entrainment of air and helps the air to 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 walls 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] Please refer to FIG. 2. The lid 1 can be made of glass or stainless steel. If the lid 1 adopts a transparent material, one can see the color of the liquid in the bottle through the lid 1 and judge whether the concentration has reached the requirement. The lid 1 is provided with a lid thread 28 to facilitate a removable connection with the connecting part 2.

[0043] Please refer to Figures 3 to 5. In some embodiments, the connecting part 2 has a connecting part housing 5, a connecting part inner embedded part 6 and a connecting part inner fitted part 7. The connecting part housing 5 is configured in a cylindrical shape and includes a hollow cavity and two upper and lower open ends. The connecting part housing 5 is located outside the connecting part 2, and the inner diameter of the connecting part housing 5 is larger than the connecting part inner embedded part 6 and the connecting part inner fitted part 7, so that the connecting part inner embedded part 6 and the connecting part inner fitted part 7 can be attached and fixed inside the connecting part housing 5, and the connecting part 2 can be assembled.

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

[0045] Please refer to 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 the first recess 34 and the second recess 35 of the water seal packing 8, respectively (see FIG. 6 and FIG. 16), so that the water seal packing 8 is fixed 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 packing 8 to the connecting part inner fitting part 7 so that the water seal packing 8 will not be deformed or fall off when the filter element 3 is installed, and to improve the sealing effect of the water seal packing 8.

[0046] See Figures 7 and 8. The infusion storage portion 4 of the tea strainer drinking bottle includes 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 from each other, 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 the surface tension of the liquid flowing through the filter holes 15 to be different, making it difficult for the head space of the tea infuser drinking bottle to become a vacuum. Reducing the formation of this vacuum layer reduces the possibility of the liquid being blocked, optimizing the usage performance of the tea infuser drinking bottle.

[0049] See FIG. 11. 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 of the filter 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 the air pressure to be balanced. At the same time, the size of the filter holes 15 must be set to a size that does not allow tea debris (whole tea leaves) to pass 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 that the surface tension of the liquid flowing through these filter holes 15 is different, making it difficult to generate a vacuum in the upper space of the drinking bottle with tea strainer, reducing the possibility of liquid clogging due to the vacuum layer, and optimizing the usage performance of the drinking bottle with tea strainer.

[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, and the distance between two adjacent rows of filter holes 15 is different. By varying the spacing of the filter holes 15 arranged in a row, the possibility of a vacuum on the top of the drinking cup (lid) is reduced.

[0052] See Fig. 13. In some embodiments, the bottom wall of the filter element 3 is configured to protrude toward the bottom wall of the infuser. 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 infuser can be improved, so that the tea leaves are collected at the bottom of the recessed part, and the liquid is easy to flow through the filter holes 15 without clogging.

[0053] In each of the above-mentioned implementation methods, the depth of the recess of the filter element 3 is greater than 1 / 5 of the height of the drinking bottle with tea strainer. This design ensures a sufficient depth of 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. Since the gas and liquid are separated, the vacuum is less likely to occur and the phenomenon of no liquid flowing at the bottom of the drinking bottle with tea strainer 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 strainer-equipped drinking bottle, the poured material such as solid tea is likely to block the filter element 3, reducing the effect of separating the tea leaves from the liquid.

[0056] If the depth of the inner recess of the filter element 3 exceeds 1 / 3 of the height of the strainer drinking bottle, the tea leaves and other extracting materials will always be submerged in the liquid, and the separation of the tea leaves and the liquid will not be effectively achieved. In addition, the extract will be 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 is that the filter element 3 can be lighter.

[0058] Please refer to Fig. 16. In each of the above-mentioned embodiments of the open groove 13, in order for the gas to effectively pass through the open groove 13 and achieve gas equilibrium, when the filter element is assembled in the connecting part, the entire or partial flow surface of any one of the open grooves 13 exceeds the bottom edge of the water seal packing 8, is exposed under the edge of the water seal packing 8, and faces the filter hole 15 side.

[0059] Please refer to Fig. 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 packing 8. When the filter element 3 is attached to the water seal packing 8, the filter element first portion protruding portion 16 is engaged with an upper notch of the water seal packing 8, and a part of the first portion 11 of the filter element protrudes below the edge of the water seal packing 8 toward the filter hole 15 side.

[0060] Please refer to Figures 17 and 18. The following describes another embodiment of the drinking bottle with tea strainer. Another embodiment of the present invention provides a bottle (water bottle) for integrating the functions of tea extraction and drinking. The bottle can be opened or closed with one hand, and when drinking with one hand, solids such as tea in the container will not enter the drinker's mouth together 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 lower part of the flip-open lid 18.

[0061] See Fig. 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 top 20, a sealing stopper 21, an opening switch 22, and a flip-open lid bottom 26.

[0062] The flip-open lid lower part 26 has a through hole 25, and the upper half of the drinking part 24 is inserted into the through hole 25 and protrudes from the through hole 25. The connection part of the flip-open lid upper part 20 and the flip-open lid lower part 26 is provided with an inner 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 the liquid from flowing out. The inner edge of the through hole 25 of the flip-open lid lower part 26 forms an annular inner recess, and the upper part of the filter (net) 19 is removably attached to the annular inner recess and is hermetically connected with the connecting part 2 and the flip-open lid 18. By adopting the above connection method, the flip-open lid 18 and the extract storage part 4 are attached so as to be easily disassembled.

[0063] The extract storage 4 is used as a container for storing the extract liquid and water. The outer shape of the extract storage 4 can be cylindrical, rectangular, hexagonal, octagonal, or any other shape, and the shape is not limited. The top of the extract storage 4 is open, and the bottom is sealed. The top of the extract storage 4 is provided with a connection structure such as a thread, and the extract storage 4 is sealedly connected to the connecting part 2, the lid 1, or the flip-open lid 18 to prevent leakage. The extract storage 4 has a receiving cavity, and can store water and tea leaves. Of course, tea leaves can be placed in the filter cavity 37 described later to facilitate drinking 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 serves as the bottom wall of the filter cavity 37, and the filter (mesh) 19 serves 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 by the filter (mesh) 19 alone. In some embodiments, the filter cavity 37 can 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 and tea bags are placed in the filter cavity 37. The filter cavity 37 is configured to communicate with the extract storage section 4 through the filter hole 15 provided in the wall of the filter cavity 37. If the filter hole 15 is not taken into account, 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 material such as tea leaves are left in the filter cavity 37 unless a portion of the filter cavity is opened, otherwise the brewing solids would flow 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, solids such as tea leaves are first put into the filter cavity 37, and then the filter cavity 37 is closed. Then, during the tea drinking process, the solids are always left in the filter cavity 37 and do 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 are combined to form a filter cavity 37. The filter cavity 37 functions to pass liquids and not to pass solids such as tea. This design allows the drinking bottle with tea strainer to have the multi-function of a teapot for brewing tea, a drinking bottle for drinking, and preventing solids from entering the drinker's mouth when drinking, which improves the convenience of the drinking bottle with tea strainer. Moreover, 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 when drinking, which is particularly suitable for one-handed drinking.

[0067] In some embodiments, the filter element 3 adopts 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-mentioned embodiment in which the filter element 3 is removably connected, since the filter element 3 is removably connected, the filter element 3 can be easily removed, so that the filter bottom and the filter element 3 can be easily cleaned. Also, the filter element 3 with different functions and effects can be easily removed and replaced by replacing different filter hole sizes and filter depth specifications as needed.

[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 the 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, and cleaning of the inside of the flip-open lid 18 and the filter 19 can be facilitated. In addition, the filter 19 can be easily replaced with one having a different filter hole specification as required, and various functions and effects can be achieved.

[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 are structured with a filtering function. If necessary, the solids to be extracted or already extracted, such as tea leaves, will stay in the filter cavity 37 without entering the extract storage.

[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 that tea leaves will block 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 as follows. 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 means that there are three slits, and one end of the three slits converge. In the filter holes 15 with herringbone structure, even if the size of the filter holes 15 is small, the fluid can easily pass through without the filter holes 15 adsorbing the liquid. The circular filter holes 15 are convenient for processing and manufacturing. The slit-shaped filter holes 15 are convenient for processing and manufacturing, and have a high fluid passing rate. The rectangular filter holes 15 are convenient for processing and manufacturing.

[0074] The following is divided into several embodiments to describe the formation of the filter cavity 37. According to different installation and connection methods of the filter element 3 and the filter 19, there are the following methods. First, the filter element 3 and the filter 19 are removably attached together, and the whole is attached to the flip-open lid 18. Second, the filter element 3 and the filter 19 are removably attached together, and the whole is attached to the extract storage part 4. Third, the filter element 3 and the filter 19 are removably attached together, and the whole is integrally attached to the connecting part 2. Fourth, the filter element 3 and the extract storage part 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 are combined 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, snap structures, etc. Both the filter element 3 and the filter 19 are configured in a concave shape, and the concave depth of the filter element 3 is greater than the concave depth of the filter 19. The concave direction of the filter element 3 and the concave direction of the filter 19 may be the same or opposite. For example, the filter element 3 is concave toward the bottom of the extract storage part 4, and the filter 19 is concave toward the bottom of the extract storage part 4. This structure not only has a relatively large space for placing solid objects, but also makes it easy to install. Alternatively, the filter element 3 is concave toward the bottom of the extract storage part 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 depth of the filter element 3 and the depth of the filter 19, so there is more space for storing solid objects. Alternatively, filter element 3 is configured to be flat and filter 19 is configured to be concave, with filter element 3 being disposed in the opening of filter 19 .

[0076] It can be seen that by reasonably setting the positions of the male and female threads, a removable and sealed connection can be realized 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 removable connection between the filter element 3 and the filter 19 can also be realized.

[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, integrated 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 walls of the extract storage section 4 are 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. The above-mentioned drinking bottle with tea strainer is used as follows.

[0085] (i) A process of using a drinking bottle with a tea strainer and a sealed lid 1: In the first method, the object to be steeped is placed in the filter element 3 arranged in the connecting part 2, the lid 1 and the connecting part 2 are connected, an appropriate amount of water or hot water is poured into the extract storage part 4, and then the filter element 3 and the lid 1 are attached to the connecting part 2, and then the tea is brewed upside down. When the user judges that the substance to be steeped has an appropriate taste, the drinking bottle with tea strainer is turned upside down to an upright position. At this time, the user can drink from the opening of the extract storage part 4. This method is suitable for steeping objects that have a limited steeping time and should not be steeped for a long time. The appropriate amount of water to be poured in in this method is the amount of water that is poured in and does not exceed the bottom of the filter element 3. Therefore, the extraction is performed in an upside down position, and the water or hot water is separated from the object to be steeped when the drinking bottle with tea strainer is turned upright.

[0086] The second method involves placing the immersion object into the extract storage part 4, pouring an appropriate amount of cold or hot water into the extract storage part 4, and attaching it to the lid 1 which is fitted with the connecting part 2 and the filter element 3. When the user determines that the immersion substance has the appropriate taste, he or she can remove the lid 1 and pour the extract from the extract storage part 4 through the connecting part 2 with the attached filter element 3 into the lid 1 or other drinking cup for drinking.

[0087] (ii) The process of using the tea strainer drinking bottle with retractable flip-open lid 18: In the first method, the object to be immersed is placed in the filter element 3 attached to the connecting part 2, and the flip-open lid 18 is connected to the connecting part 2. After pouring an appropriate amount of water or hot water into the extract storage part 4, it is attached to the connecting part 2 with the filter element 3 and the flip-open lid 18 attached. The drinking bottle with tea strainer is turned upside down and immersed. When the user judges that the immersed substance has a suitable taste, the drinking bottle with tea strainer is turned upside down from there. The user can drink the beverage from the opening of the flip-open lid. This method is suitable for immersing objects that have a limited immersion time and should not be immersed for a long time. The appropriate amount of water to be poured in this method should be such that the amount of water poured does not exceed the bottom of the filter element 3. Therefore, the immersion is performed in an upside-down position, and the water or hot water is separated from the object to be immersed when the bottle is turned upside down. The user can open the flip-open lid 18 with one hand and then drink, which is very convenient.

[0088] The second method is to place the soaking object into the extract storage part 4, pour an appropriate amount of cold or hot water into the extract storage part 4, and then attach it to the connecting part 2 equipped with the flip-open lid 18 and the filter element 3. When the user judges that the soaked substance has a suitable taste, he or she can open the flip-open lid 18 with one hand and drink it.
