Description

Technical Field

[0001] This invention belongs to the field of drinking vessel technology, and particularly relates to a tea brewing cup. Background Technology

[0002] Most tea-infusing thermos cups currently on the market, designed for tea brewing with a tea-water separation mechanism, involve inverting the cup to fully submerge the tea leaves in boiling water, and then repositioning the cup after brewing to achieve the so-called tea-water separation, as illustrated in the CN222055121U smart tea maker. This design offers two ways to drink the tea after brewing: 1) unscrew the lid, leaving the tea container at the rim, and drink through the container (or pour out the tea before drinking); 2) remove both the lid and the tea container from the rim and drink through the rim. With the first method, the tea still passes through the tea leaves when drinking from the inverted cup, affecting the final concentration. While the second method avoids this problem, a significant amount of water remains in the tea container after brewing, often wetting the table when removing it. Both methods negatively impact the user experience. Summary of the Invention

[0003] This invention provides a tea brewing cup that eliminates the need to remove the tea container component when drinking tea. This solves the problem in the prior art where tea soup repeatedly flows through the tea leaves, affecting the taste, and avoids the technical problem of tea soup easily dripping and wetting the table caused by removing the tea container component.

[0004] To achieve the above objectives, the present invention adopts the following technical solution.

[0005] A tea infuser cup includes a lid, a tea infuser assembly, and a cup body. The lower end of the tea infuser assembly is detachably and sealingly connected to the mouth of the cup body. The lid is detachably and sealingly connected to the upper port of the tea infuser assembly. The tea infuser assembly includes an outer cylinder, an inner cylinder, and a check valve. The outer cylinder is a cylindrical structure extending vertically, with its upper and lower ends detachably and sealingly connected to the mouths of the lid and the cup body, respectively. The inner cylinder is a cylindrical structure extending vertically, located inside the outer cylinder. A first gap exists between the outer wall of the inner cylinder and the inner wall of the outer cylinder, and a second gap exists between the upper port of the inner cylinder and the lid. A filter screen is provided at the lower end of the inner wall of the inner cylinder, and the filter screen has several vertically extending through holes. The upper surface of the filter screen and the inner wall of the inner cylinder together form the tea infuser. The check valve is located below the filter screen and at the lower port of the inner cylinder. When brewing tea, the teacup is inverted, and the check valve is closed under gravity, sealing the lower port of the inner cylinder. The liquid in the cup passes through the first gap and the second gap into the tea chamber. After brewing, the teacup is flipped back to its upright position, and the check valve is opened under gravity, releasing the seal on the lower port of the inner cylinder. The liquid in the tea chamber passes through the filter screen, flows through the check valve, and then enters the cup. When drinking tea, the lid is opened, the teacup is inverted, and the check valve is closed under gravity, sealing the lower port of the inner cylinder. The liquid in the cup flows through the first gap and then out from the upper port of the outer cylinder.

[0006] Furthermore, the lower port of the inner cylinder is symmetrically provided with hinge holes; the check valve includes a first check plate and a second check plate, both of which are semi-circular; the outer diameters of the first check plate and the second check plate are the same and are adapted to the inner diameter of the lower port of the inner cylinder; the straight edges of the first check plate and the second check plate are hinged to each other by a first hinge shaft; the straight edge of the first check plate is hinged to the hinge hole by a second hinge shaft, so that the first check plate and the second check plate can rotate relative to each other about their joint diameter; a stop portion is provided on the inner wall of the lower port of the inner cylinder, which is used to support the outer edges of the first check plate and the second check plate from the back when the check valve is in the closed state.

[0007] Furthermore, both the first and second anti-reverse plates have built-in gravity blocks.

[0008] Furthermore, the tea container assembly also includes an inner cylinder cover; the inner cylinder cover is detachably fitted onto the upper port of the inner cylinder; the inner cylinder cover is provided with several water inlet holes that extend vertically.

[0009] Furthermore, the outer side wall of the inner cylinder cover is evenly distributed with multiple protrusions; the inner wall of the inner cylinder is provided with concave portions corresponding to the protrusions; the protrusions and concave portions cooperate to allow the inner cylinder cover to be detachably fitted onto the upper port of the inner cylinder.

[0010] Furthermore, the inner wall of the upper port of the inner cylinder is provided with a limiting step; when the inner cylinder cover is closed on the upper port of the inner cylinder, the limiting step is used to support the lower surface of the inner cylinder cover.

[0011] Furthermore, the upper surface of the inner cylinder cover is also provided with a raised gripping part.

[0012] Furthermore, the inner wall of the outer cylinder is provided with a support portion; the outer wall of the inner cylinder is provided with a limiting protrusion; the limiting protrusion abuts against the support portion along the axial direction to limit the axial displacement of the inner cylinder relative to the outer cylinder, thereby realizing the detachable assembly of the inner cylinder within the outer cylinder.

[0013] Furthermore, the supporting part consists of a plurality of buckle grooves evenly distributed along the inner wall of the outer cylinder, each buckle groove having an upward opening; the limiting protrusion consists of a plurality of protrusions correspondingly disposed on the outer wall of the inner cylinder, each protrusion being able to be inserted into the corresponding buckle groove through the upward opening.

[0014] Compared with the prior art, the tea brewing cup provided by the present invention has the following beneficial effects: 1. By installing a gravity-controlled check valve at the lower port of the inner cylinder, and in conjunction with the first gap between the outer and inner cylinders and the second gap between the upper port of the inner cylinder and the lid, two independent liquid flow paths are constructed for brewing and drinking tea. When drinking tea upside down, the check valve automatically closes under gravity, and the tea in the cup flows out from the upper port of the outer cylinder only through the first gap. It can be drunk directly without removing the tea container, and the tea will not come into contact with the brewed tea leaves in the tea container, thus ensuring that every sip of tea maintains a consistently pure taste. This effectively solves the problem in existing technologies where the tea repeatedly flows through the tea leaves when drinking tea upside down, causing changes in concentration and affecting the drinking experience. 2. The entire tea brewing, tea liquor separation, and tea drinking process is achieved through the automatic action of the check valve following the direction of gravity. When brewing tea, inverting the valve closes the lower port to form the steeping chamber. After brewing, the lower port immediately opens to complete the tea liquor separation. When drinking tea, inverting the valve again closes the lower port again to form an independent water outlet channel. The entire process does not require the user to manually operate the valve or switch the water circuit. It is simple to operate and convenient to use. 3. The check valve adopts a purely mechanical gravity-driven principle, with a simple and reliable structure. It can achieve automatic opening and closing without the need for additional driving components such as springs and magnets. It has fewer parts, is easy to manufacture and assemble, and has low cost.

[0023] To make the technical solution of the present invention clearer, the following description is provided in conjunction with the appendix. Figures 1 to 8 This invention will be described in detail below. It should be understood that the specific embodiments described in this specification are merely for explaining the invention and are not intended to limit the scope of protection of the invention.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0025] This invention provides a tea brewing cup that creatively incorporates a gravity-controlled check valve at the lower end of the inner cylinder of the tea container assembly. By cleverly utilizing the change in the direction of gravity, the check valve automatically switches between open and closed states depending on the tea brewing cup's orientation, thereby enabling brewing, tea separation, and tea drinking functions. Furthermore, when the cup is inverted for drinking, the tea liquor will not come into contact with the tea leaves in the tea container again, ensuring the pure taste of the tea.

[0026] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1 to 8As shown, the tea cup in this embodiment mainly includes a lid 1, a tea infuser assembly 2, and a cup body 3. The cup body 3 is a container with an upward-opening design for holding the water used for brewing tea and the resulting tea liquor. The tea infuser assembly 2 is a separate module, its lower end detachably and sealed to the opening of the cup body 3, for example, through a threaded connection or a snap-fit ​​connection. The lid 1 is detachably and sealed to the upper end of the tea infuser assembly 2, also using a threaded or snap-fit ​​connection.

[0028] The core innovation of this invention is the tea storage component 2, which specifically includes an outer cylinder 21, an inner cylinder 22, and a check valve 23.

[0029] The outer cylinder 21 is a cylindrical structure that runs vertically through the body, forming part of the external framework and liquid channel of the tea container assembly 2. The lower end of the outer cylinder 21 is detachably and sealed to the mouth of the cup body 3, while the upper end is detachably and sealed to the cup lid 1.

[0030] The inner cylinder 22 is also a cylindrical structure that runs vertically through the outer cylinder 21, and it is coaxially or nearly coaxially positioned inside the outer cylinder 21. The outer wall of the inner cylinder 22 is not tightly fitted to the inner wall of the outer cylinder 21, but rather maintains a surrounding gap, known as the first gap. Simultaneously, a space for liquid flow is also maintained between the upper end of the inner cylinder 22 and the inner top surface of the closed cup lid 1, known as the second gap. A filter screen 221 (which can be integrally formed, fixedly connected, or detachably connected) is located at the lower end of the inner wall of the inner cylinder 22. The filter screen 221 is covered with multiple vertically through holes that allow only liquid and small particles to pass through while trapping tea leaves. The upper surface of the filter screen 221 and the inner wall of the inner cylinder 22 together form a chamber for containing tea leaves, known as the tea compartment 220.

[0031] The check valve 23 is located below the filter screen 221 and installed at the lower port of the inner cylinder 22. This check valve 23 is a one-way valve that operates based on the principle of gravity. Its structure is configured such that when the entire tea cup is in an upright position, the check valve 23 automatically opens under its own gravity, keeping the lower port of the inner cylinder 22 unobstructed; when the tea cup is inverted (i.e., the rim is facing down), the check valve 23 automatically closes under the opposite gravity, tightly sealing the lower port of the inner cylinder 22.

[0032] To optimize water intake and distribution, and to prevent tea leaves from escaping from the upper port of the inner cylinder 22, the tea container assembly 2 may also include an inner cylinder cover 24. The inner cylinder cover 24 is detachably fitted onto the upper port of the inner cylinder 22, and its cover body is provided with multiple vertically penetrating water inlet holes 241. The diameter of the water inlet holes 241 is smaller than the size of a typical tea leaf.

[0033] To facilitate quick disassembly and installation of the inner cylinder cover 24, a convex-concave fit structure is adopted between the inner cylinder cover 24 and the inner cylinder 22. Specifically, multiple outwardly protruding protrusions 242 are evenly arranged circumferentially on the outer side wall of the inner cylinder cover 24; correspondingly, a recess 225 matching the shape and position of the protrusions 242 is provided on the inner wall of the upper end of the inner cylinder 22. During installation, the protrusions 242 of the inner cylinder cover 24 are aligned with the recesses of the inner cylinder 22 and pressed or screwed in to achieve a closed fit; disassembly is performed in reverse, which is convenient and quick.

[0034] As an alternative to the tongue-and-groove fit, the inner cylinder cover 24 can also be detachably connected to the upper port of the inner cylinder 22 by screwing it on, which is a more secure connection. However, the tongue-and-groove fit structure is more convenient in scenarios where the user's hands are wet or when quick opening and closing is required.

[0035] Furthermore, to provide more reliable positioning and support for the inner cylinder cover 24, an inwardly extending annular limiting step 223 can be provided on the inner wall of the upper port of the inner cylinder 22. When the inner cylinder cover 24 is closed, the lower edge of the inner cylinder cover 24 just abuts against the upper surface of the limiting step 223, which provides stable support. To facilitate the user's removal and installation of the inner cylinder cover 24 by pinching it with their fingers, a raised gripping part 243, such as a small pull ring, a raised button, or a handle, can also be provided at the center of the upper surface of the inner cylinder cover 24.

[0036] For the assembly relationship between the outer cylinder 21 and the inner cylinder 22, the present invention provides a simple detachable structure. A support portion 211 is provided on the inner wall of the outer cylinder 21, and a limiting protrusion 224 is correspondingly provided on the outer wall of the inner cylinder 22. During assembly, the inner cylinder 22 is inserted from the upper end or lower port of the outer cylinder 21, so that the limiting protrusion 224 abuts against and engages with the support portion 211 along the axial direction, thereby limiting the axial displacement of the inner cylinder 22 relative to the outer cylinder 21, so that the inner cylinder 22 is stably suspended inside the outer cylinder 21.

[0037] In one specific embodiment, the supporting portion 211 consists of multiple snap-fit ​​grooves evenly distributed circumferentially along the inner wall of the outer cylinder 21, each snap-fit ​​groove having an upward-facing opening. The limiting protrusions 224 are multiple protrusions correspondingly provided on the outer wall of the inner cylinder 22. During assembly, each protrusion of the inner cylinder 22 is aligned with the upward-facing opening of the snap-fit ​​groove and inserted downwards to complete the assembly. The structure is simple and the operation is convenient.

[0038] The following is a detailed description of the specific structure of a preferred check valve 23.

[0039] like Figure 3As shown, two hinge holes 222 are symmetrically formed at the lower port edge of the inner cylinder 22. The check valve 23 mainly consists of two semi-circular valve plates, namely the first check plate 231 and the second check plate 232. The outer diameter of the first check plate 231 and the second check plate 232 is the same, and when the two are spliced ​​into a complete circle, the outer diameter of the circle matches the inner diameter of the lower port of the inner cylinder 22, which can precisely close the lower port.

[0040] The straight edges (i.e., diameter edges) of the first anti-reverse plate 231 and the second anti-reverse plate 232 are hinged together by a first hinge pin to form a whole. Then, the straight edge of one of the anti-reverse plates (the first anti-reverse plate 231 in this example) is hinged to the hinge hole 222 of the inner cylinder 22 by a second hinge pin. In this way, the whole composed of the first anti-reverse plate 231 and the second anti-reverse plate 232 can rotate relative to each other around their splicing diameter (i.e., hinge axis) to achieve folding (opening) and unfolding (closing).

[0041] To prevent the check valve 23 from being bent and malfunctioning due to reverse water pressure when closed (i.e., when unfolded into a circle), a stop is provided on the inner wall of the lower port of the inner cylinder 22, located below the filter screen 221. When the tea cup is inverted, the first check plate 231 and the second check plate 232 flip downwards and unfold under the action of reverse gravity. Their outer edges are supported by the lower stop, thus forming a stable planar support and reliably sealing the lower port of the inner cylinder 22. The stop can be a continuous annular step or multiple spaced blocks.

[0042] To increase the sensitivity and reliability of the check valve 23's closing action, gravity blocks 233 made of a high-density material are embedded inside both the first check plate 231 and the second check plate 232. The gravity blocks 233 enhance the valve plate's response to changes in gravity, ensuring rapid and tight closure even when inverted.

[0043] The following describes in detail the usage process and working principle of this tea infuser.

[0044] During the tea preparation stage, place the teacup upright. First, unscrew the connection between the cup body 3 and the tea container assembly 2, and pour an appropriate amount of boiling water into the cup body 3. Then, open the inner lid 24, put an appropriate amount of tea leaves into the tea container 220, and then close the inner lid 24. Finally, tighten the cup body 3 containing the tea container assembly 2 to seal it again (or first, unscrew the connection between the tea container assembly 2 and the cup lid 1, open the inner lid 24, put an appropriate amount of tea leaves into the tea container 220; then pour an appropriate amount of boiling water into the cup body through the tea container assembly 2, and then close the inner lid 24. Finally, screw the cup lid 1 back into the tea container assembly 2 to seal it).

[0045] During the tea brewing stage, such as Figure 6As shown. The user inverts the teacup so that the lid 1 faces down and the bottom of the body 3 faces up. At this time, the boiling water in the body 3 flows downward under the influence of gravity, filling the first gap. Simultaneously, the first check valve 231 and the second check valve 232 of the check valve 23 reverse the direction of gravity due to their own gravity and that of the built-in gravity block 233, flipping downward to a horizontal position and sealing the lower port of the inner cylinder 22. The boiling water cannot directly enter the tea chamber 220, but can only flow along the first gap, pass through the second gap, and then enter the tea chamber 220 through the water inlet 241 on the inner cylinder lid 24, completely submerging the tea leaves. Thus, the tea is extracted in the sealed tea chamber 220.

[0046] After brewing the tea, as follows Figure 7 As shown. The user flips the teacup back to its upright position. At this time, the check valve 23 and its gravity block 233 reset under the action of gravity, the first check plate 231 and the second check plate 232 flip downwards, releasing the seal on the lower port of the inner cylinder 22, and the check valve 23 is fully opened. The brewed tea in the tea chamber 220 passes through the bottom filter 221 under the action of gravity, and flows smoothly into the cup body 3 below through the opened check valve 23, while the tea leaves are trapped in the tea chamber 220 by the filter 221, achieving complete separation of tea and tea soup.

[0047] During the tea-drinking stage, such as Figure 8 As shown. The user simply opens the lid 1 and inverts the teacup again to drink. In this inverted state, based on the same principle as during the brewing stage, the check valve 23 closes tightly again under gravity. The pure tea stored in the cup body 3 flows out under gravity, flowing directly from the upper port of the opened outer cylinder 21 through the first gap between the outer cylinder 21 and the inner cylinder 22, and into the user's mouth or teaware. Because the check valve 23 closes the lower port, the tea will not come into contact with the tea leaves already steeped in the tea container 220 during the entire outflow path, thus ensuring that every sip of tea tastes consistently pure and authentic, perfectly solving the tea-drinking pain points mentioned in the background art.

[0048] It should be noted that the specific structure of the check valve 23 is not limited to the gravity valve form using a hinged semi-circular plate and a gravity block as described above. In other embodiments of the present invention, the check valve 23 can also adopt other structures that achieve automatic opening and closing based on gravity drive. For example, the check valve 23 can be an integral flap, one side of which is hinged to one side of the lower port of the inner cylinder, and the flap has a built-in gravity block; when upright, the flap flips downward around the hinge axis under the action of gravity, opening the lower port; when inverted, the flap flips upward under the action of reverse gravity, closing the lower port. As another example, the check valve 23 can be a valve core that can move up and down in the vertical direction, with a counterweight at its bottom; when upright, the valve core sinks under the action of gravity, leaving the valve seat, and the lower port opens; when inverted, the valve core presses against the valve seat under the action of reverse gravity, and the lower port closes. These variant structures all utilize the principle of the change of gravity direction in the inverted and upright states to achieve the same automatic switching function, and all should fall within the protection scope of the present invention.

[0049] The above descriptions are merely specific examples of the present invention and do not constitute any limitation on the present invention. Obviously, those skilled in the art, after understanding the content and principles of the present invention, may make various modifications and changes in form and detail without departing from the principles and structure of the present invention; however, these modifications and changes based on the spirit of the present invention are still within the scope of protection of the claims of the present invention.
