Description

Technical Field

[0001] This invention relates to the field of drinking vessel technology, and more particularly to a detachable thermos cup that maintains the breathability of the purple clay inner liner. Background Technology

[0002] The dual-pore structure of Zisha clay consists of: chain-like pore groups (open pores): distributed between minerals such as quartz and clay and the aggregates, forming voids during the shaping, drying, and firing shrinkage of the minerals. These pores are interconnected to form a "chain," with a width mostly below 10-20 micrometers, allowing gas molecules to pass through freely; Micropores (closed pores): These are distributed inside the agglomerates (particles composed of quartz, silicates, etc.). These are tiny gaps created by the different shrinkage rates of the minerals inside the agglomerates during firing. They are extremely small, about 1.3 micrometers in diameter, and water molecules cannot pass through them, thus playing a "water-blocking" role.

[0003] Zisha clay, with its unique dual-pore structure (an interweaving of open and closed pores), possesses the natural property of being "breathable but waterproof," and is widely recognized as one of the most suitable materials for brewing tea. Using Zisha clay to make the inner liner of a thermos can preserve the aroma of tea, delay its spoilage, and also serve as a "nurturing" agent for the cup.

[0004] However, in existing thermos cup structures, the inner liner of the purple clay is usually completely covered by a metal or plastic outer shell, forming a sealed or nearly sealed interlayer between the inner liner's outer wall and the outer shell. While this interlayer can provide some insulation, it also cuts off the gas exchange between the purple clay outer wall and the outside air, severely weakening or even eliminating the "breathability" of the purple clay. At the same time, condensation caused by temperature differences easily accumulates in the sealed interlayer, which, if it cannot drain over time, leads to mold growth and unpleasant odors, ultimately affecting health. Summary of the Invention

[0005] The present invention aims to at least partially solve one of the technical problems in the related art.

[0006] To achieve the above objectives, the present invention proposes a detachable insulated cup that maintains the breathability of the purple clay inner liner, comprising a purple clay inner liner, an outer shell covering the purple clay inner liner, the outer shell being detachably and fixedly connected to the purple clay inner liner, and a breathable interlayer being provided between the purple clay inner liner and the outer shell; a base being provided at the bottom of the purple clay inner liner, and a first vent hole being provided on the base corresponding to the position of the breathable interlayer to connect the breathable interlayer with the external environment; and a cup lid being detachably provided on the outer shell corresponding to the opening end of the purple clay inner liner.

[0007] This invention features a breathable interlayer between the outer shell and the inner clay liner, with a first vent hole on the base corresponding to the interlayer's location. This allows the interlayer to connect with the external environment, creating a controllable gas exchange channel between the outer wall of the inner clay liner and the outside air. The double-pore structure of the inner clay liner enables continuous gas exchange with the outside air, maintaining the "breathing" characteristic of the clay and promoting the preservation of tea aroma and freshness. Simultaneously, the air in the breathable interlayer forms a heat insulation layer, providing thermal insulation. Furthermore, the outer shell and inner clay liner are detachably connected, allowing users to remove the inner clay liner for independent cleaning, thus eliminating the hygiene concerns associated with condensation and tea stains that cannot be removed from the interlayer.

[0008] Optionally, multiple first vent holes are provided, and the multiple first vent holes are evenly distributed in a ring on the end face of the base, and the first vent holes penetrate the base.

[0009] Furthermore, the bottom of the base is integrally provided with a lifting seat inside the plurality of vent holes, so that the first vent hole can be detached from the plane when the thermos cup is placed on a flat surface.

[0010] Furthermore, the lifting seat extends integrally with a stabilizing ring seat on the periphery, and the side wall of the stabilizing ring seat is provided with a ventilation ring groove, which is connected to the first vent hole.

[0011] Furthermore, a second vent hole is provided through the axial position of the base and the lifting seat, and a bottom interlayer is formed between the base and the purple clay inner liner. The second vent hole is used to connect the bottom interlayer to the external environment.

[0012] Furthermore, the outer shell is provided with an edge-sealing insertion groove at the opening position of the purple clay inner liner. The edge-sealing insertion groove is annular, and the purple clay inner liner is inserted into the edge-sealing insertion groove.

[0013] Furthermore, sealing strips are provided at both the end of the purple clay inner liner facing the edge insertion groove and the end of the purple clay inner liner facing the base; All sealing strips are made of food-grade silicone.

[0014] Furthermore, the outer casing is made of titanium.

[0015] Furthermore, a temperature sensor is installed inside the cup lid, and a display screen is installed on the top of the cup lid, with the temperature sensor electrically connected to the display screen.

[0016] Furthermore, a receiving groove is provided at the bottom of the lifting seat around the second vent, and an anti-slip silicone pad is provided in the receiving groove.

[0017] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] This invention proposes a detachable thermos cup that maintains the breathability of the purple clay inner liner, as described below. Figures 1 to 4 A detailed explanation will be provided.

[0023] A detachable insulated cup that maintains the breathability of a purple clay inner liner includes a purple clay inner liner 1, an outer shell 2 covering the purple clay inner liner 1, and a detachable and fixed connection between the outer shell 2 and the purple clay inner liner 1. A breathable interlayer 3 is provided between the purple clay inner liner 1 and the outer shell 2. A base 4 is provided at the bottom of the purple clay inner liner 1, and a first vent 41 is provided on the base 4 corresponding to the position of the breathable interlayer 3 to connect the breathable interlayer 3 and the external environment. A cup lid 5 is detachably provided on the outer shell 2 at one end corresponding to the opening of the purple clay inner liner 1.

[0024] This invention establishes a breathable interlayer 3 between the outer shell 2 and the inner clay liner 1, and creates a first vent 41 on the base 4 corresponding to the location of the breathable interlayer 3. This allows the breathable interlayer 3 to communicate with the external environment through the first vent 41, creating a controllable gas exchange channel between the outer wall of the inner clay liner 1 and the outside air. This enables the double-pore structure of the inner clay liner 1 to continuously exchange gases with the outside air, maintaining the "breathing" characteristic of the clay, which is beneficial for preserving tea aroma and freshness. Simultaneously, the air in the breathable interlayer 3 forms a heat insulation layer, providing heat retention. Furthermore, the outer shell 2 and the inner clay liner 1 are detachably connected, allowing users to remove the inner clay liner 1 from the outer shell 2 for independent cleaning, thus eliminating the hygiene concerns associated with condensation and tea stains that cannot be cleaned from the interlayer. During normal use, condensation and moisture flow to the bottom and are discharged through the first vent 41, preventing long-term water accumulation in the breathable interlayer 3 and improving hygiene. Specifically, when hot water or hot tea is placed in the purple clay inner liner 1, the temperature of the inner liner 1 rises. The air in the breathable interlayer 3 is heated, its density decreases, and it rises. External cold air enters the breathable interlayer 3 from the bottom through the first vent 41, forming a natural convection circulation. During this process, the open pores on the outer wall surface of the purple clay inner liner 1 continuously exchange gases with the flowing air in the breathable interlayer 3, allowing the double-pore structure of the purple clay to continuously "breathe." Water vapor molecules and aromatic molecules in the tea soup can diffuse outward through the open pores on the wall of the purple clay inner liner 1, preventing the tea soup from developing a cooked taste due to over-steeping. At the same time, a small amount of external air slowly permeates into the tea soup, which is conducive to the moderate oxidation of components such as tea polyphenols, making the tea soup taste more mellow, thus achieving the technical effect of preserving the tea aroma and keeping the tea soup fresh. Meanwhile, the air in the breathable interlayer 3 forms an air insulation layer, which, combined with the heat storage characteristics of the purple clay material, maintains both breathability and heat preservation performance. In addition, the outer shell 2 and the purple clay inner liner 1 are detachably fixedly connected, allowing users to remove the purple clay inner liner 1 from the outer shell 2 for independent cleaning, effectively solving the hygiene problem of condensation and tea stains that cannot be cleaned in the interlayer.

[0025] In some embodiments, multiple first vent holes 41 are provided, and the multiple first vent holes 41 are evenly distributed in a ring on the end face of the base 4, and the first vent holes 41 penetrate the base 4.

[0026] Understandably, the multiple first vent holes 41 are evenly distributed around the end face of the base 4, allowing external air to enter the breathable interlayer 3 uniformly from the base 4 in all directions. Compared to a single vent hole, the dispersed arrangement of multiple vent holes significantly increases the total cross-sectional area for gas exchange, improving the exchange efficiency between the gas inside the breathable interlayer 3 and the external environment. Simultaneously, the uniformly distributed structural design avoids uneven gas exchange caused by localized airflow obstruction, ensuring consistent breathability across the outer wall of the purple clay inner liner 1. Furthermore, the dispersed arrangement of multiple vent holes also enhances the anti-clogging capability of the breathable structure. Even if some vent holes are accidentally blocked, the remaining vent holes can still maintain basic gas exchange function, guaranteeing the reliability of the breathable structure.

[0027] In some embodiments, the bottom of the base 4 is integrally provided with a lifting seat 42 inside multiple vent holes, so that the first vent hole 41 can be detached from the plane when the thermos cup is placed on a flat surface.

[0028] Understandably, the lifting seat 42 protrudes downwards from the bottom of the base 4, creating a gap between the area of ​​the base 4 end face excluding the lifting seat 42 and the placement surface. When the thermos cup is placed on a flat surface such as a table, the lifting seat 42 directly contacts the table, raising the entire end face of the base 4 to a certain height. This exposes the first vent 41, located on the end face of the base 4, within the aforementioned gap, preventing direct contact with the table. This structure ensures that the first vent 41 remains connected to the external environment during actual use, allowing external air to freely enter through the gap. This effectively solves the technical problem in existing technologies where the vent at the bottom of the cup is directly located on the bottom surface and is completely blocked by the table during use, causing the venting function to fail in actual use.

[0029] In some embodiments, the lifting seat 42 integrally extends a stabilizing ring seat 43 to the periphery, and a ventilation ring groove 44 is provided on the side wall of the stabilizing ring seat 43, which is connected to the first vent hole 41.

[0030] Understandably, the stabilizing ring 43 extends from the bottom of the lifting seat 42 outwards, increasing the contact area between the bottom of the thermos and the placement surface, thereby improving the stability of the thermos when placed on a table and preventing it from tipping over due to its high center of gravity. The ventilation ring groove 44 is formed on the side wall of the stabilizing ring 43, creating a lateral air intake channel. External air can enter the first vent hole 41 from the side of the stabilizing ring 43 through the ventilation ring groove 44. This lateral air intake design has the following advantages: when the placement surface is slightly uneven, the ventilation ring groove 44 can still maintain unobstructed air intake; when there is a small amount of water on the placement surface, the ventilation ring groove 44, located on the side wall, is less likely to be blocked by a water film, ensuring that air intake is not affected; even when part of the bottom of the thermos is blocked, the ventilation ring groove 44 can still provide a reliable air intake path. Through the above structure, the ventilation ring groove 44 further enhances the environmental adaptability of the ventilation structure, ensuring that the thermos maintains stable ventilation performance in different usage scenarios.

[0031] In some embodiments, a second vent hole 45 is provided through the axial position of the base 4 and the lifting seat 42, and a bottom interlayer is formed between the base 4 and the purple clay inner liner 1. The second vent hole 45 is used to connect the bottom interlayer to the external environment.

[0032] Understandably, the second vent 45 is arranged along the axial direction of the base 4 and the lifting seat 42, forming an additional gas exchange channel in the central area of ​​the base 4. The bottom interlayer between the base 4 and the bottom of the purple clay inner liner 1 is connected to the external environment through the second vent 45, allowing the gas at the bottom of the purple clay inner liner 1 to also be exchanged through the second vent 45. Through the combined action of the first vent 41 and the second vent 45, a multi-point air intake gas exchange mode is formed at the bottom. The bottom area and side wall area of ​​the purple clay inner liner 1 can effectively participate in gas exchange, and all areas of the outer wall of the purple clay inner liner 1 can maintain a "breathing" state, further improving the breathability of the purple clay. At the same time, the second vent 45 is located at the axial position, forming an inner and outer combination with the first vent 41 located in the circumferential direction, which is conducive to the uniform flow of gas in the breathable interlayer 3 and avoids the formation of gas stagnation dead zones in the breathable interlayer 3.

[0033] In some embodiments, the outer shell 2 is provided with an edge-sealing insertion groove 6 at the opening position corresponding to the purple clay inner liner 1. The edge-sealing insertion groove 6 is annular, and the purple clay inner liner 1 is inserted into the edge-sealing insertion groove 6.

[0034] It is understandable that the edge-sealing insertion groove 6 is an annular groove structure set on the inner wall of the opening end of the outer shell 2, and its shape and size are adapted to the edge of the opening end of the purple clay inner liner 1. The edge of the opening end of the purple clay inner liner 1 is inserted into the edge-sealing insertion groove 6, and the detachable connection between the purple clay inner liner 1 and the outer shell 2 is achieved through the plug-in fit. This plug-in structure allows the user to complete the assembly simply by aligning the edge of the opening end of the purple clay inner liner 1 with the edge-sealing insertion groove 6 and pressing it down. The reverse operation allows the purple clay inner liner 1 to be removed, making assembly and disassembly operations simple and quick. At the same time, the edge-sealing insertion groove 6 forms a circumferential covering and limiting of the opening end of the purple clay inner liner 1, positioning the purple clay inner liner 1 radially to prevent radial displacement of the inner liner during use; axially, the upper wall of the edge-sealing insertion groove 6 limits the edge of the opening end of the purple clay inner liner 1 to prevent the inner liner from coming out of the outer shell 2, ensuring the structural stability of the connection between the inner liner and the outer shell 2.

[0035] In some embodiments, a sealing strip 7 is provided at one end of the purple clay inner liner 1 facing the edge insertion groove 6 and at the other end of the purple clay inner liner 1 facing the base 4; the sealing strip 7 is made of food-grade silicone.

[0036] Understandably, the sealing strip 7 at the upper end of the purple clay inner liner 1 (i.e., the end facing the edge insertion groove 6) forms a seal between the purple clay inner liner 1 and the edge insertion groove 6, preventing tea from leaking from the gap between the edge of the opening of the purple clay inner liner 1 and the outer shell 2 into the breathable interlayer 3. Similarly, the sealing strip 7 at the lower end of the purple clay inner liner 1 (i.e., the end facing the base 4) forms a seal between the bottom of the purple clay inner liner 1 and the base 4, preventing tea from flowing down the outer wall of the purple clay inner liner 1 into the area of ​​the base 4 and blocking the vents. Through the synergistic effect of the sealing strips 7 at both ends, the tea is reliably sealed within the internal space of the purple clay inner liner 1, preventing liquid from entering the breathable interlayer 3 and affecting the breathability, while also preventing tea leakage to the outside. The sealing strip 7 is made of food-grade silicone, which is safe, non-toxic, heat-resistant (can be used for a long time in the range of -40℃ to 200℃), and aging-resistant, making it suitable for use with drinking utensils. Even with prolonged contact with hot tea, it will not release harmful substances, ensuring the hygiene and safety of the beverage.

[0037] In some embodiments, the sealing strip 7 located at the top of the purple clay inner liner 1 is slidably connected to the inner wall of the edge insertion groove 6 so that the sealing strip 7 can be removed and replaced from the edge insertion groove 6; the sealing strip 7 located at the bottom of the purple clay inner liner 1 is detachably connected to the end face of the base 4 facing the purple clay inner liner 1 by a snap or thread, so as to realize the detachable installation of the sealing strip 7.

[0038] By designing the sealing strip 7 as a detachable and replaceable structure, firstly, as a consumable part, the sealing strip 7 can be replaced independently without scrapping the entire purple clay inner liner 1 or outer shell 2, extending the overall lifespan of the thermos and reducing user costs; secondly, users can flexibly replace locally aged sealing strips 7 according to actual usage, always maintaining the good sealing performance of sealing strip 7, thereby preventing tea from leaking into the breathable interlayer 3 and ensuring the long-term stable performance of the breathable function; thirdly, the detachable structure allows the sealing strip 7 to be removed for thorough cleaning, preventing bacterial growth on the surface of the sealing strip 7 and improving the product's hygiene and safety performance; finally, the sliding connection of the top sealing strip 7 and the snap / threaded connection of the bottom sealing strip 7 cooperate with each other, without interfering with each other during disassembly and assembly, allowing users to maintain the two sealing strips 7 independently, further improving the flexibility and convenience of maintenance.

[0039] In some embodiments, the outer shell 2 is made of titanium, which can be either antibacterial pure titanium or titanium alloy. Titanium, with its low density (approximately 60% of steel) and high specific strength, makes the thermos lighter and easier to carry. Titanium also exhibits excellent corrosion resistance, resisting the weak acidity in tea and the condensation formed in the breathable interlayer 3 due to temperature differences, preventing rust and corrosion, thus ensuring the thermos's lifespan. Furthermore, titanium has good biocompatibility and is a safe metal material; even with prolonged contact between the inner wall of the outer shell 2 and the air and condensation in the breathable interlayer 3, it will not release harmful metal ions, ensuring drinking water safety. Additionally, the titanium surface can be anodized to form a colorful oxide film, providing a decorative effect and meeting the aesthetic needs of different users. In another embodiment, the outer shell 2 can be made of food-grade PP or stainless steel composite material.

[0040] In some embodiments, a temperature sensor is disposed inside the cup lid 5, and a display screen 51 is disposed on the top of the cup lid 5. The display screen 51 can be an LED display screen, and the temperature sensor is electrically connected to the display screen 51. The temperature sensor is disposed inside the cup lid 5. When the cup lid 5 is closed at the opening end of the outer shell 2, the temperature sensing end of the temperature sensor is close to the edge of the opening end of the purple clay inner liner 1. The temperature of the tea in the purple clay inner liner 1 is indirectly measured by detecting the heat radiated or conducted from the opening end of the purple clay inner liner 1. The temperature data detected by the temperature sensor is transmitted to the display screen 51 through an electrical connection line. The display screen 51 displays the temperature value in digital form on the top of the cup lid 5. Users can know the real-time temperature of the tea in the cup without opening the cup lid 5, facilitating drinking at a suitable temperature and improving convenience and user experience. Since the temperature sensor is disposed inside the cup lid 5 rather than immersed in the tea, it is a non-contact temperature measurement method. The sensor does not directly contact the tea, avoiding damage from immersion in tea and ensuring the hygiene and safety of the beverage. The temperature sensor can be an NTC thermistor or a digital temperature sensor, which has the advantages of fast response speed and high measurement accuracy. In another embodiment, the cup lid 5 also integrates a Bluetooth module, which can send temperature information from the temperature sensor to other devices that can receive Bluetooth connections.

[0041] In some embodiments, the bottom of the lifting seat 42 is provided with a receiving groove 46 around the second vent 45, and an anti-slip silicone pad 8 is provided in the receiving groove 46.

[0042] It is understood that the receiving groove 46 is a recessed space located at the bottom of the lifting base 42, around the periphery of the second vent 45, and the anti-slip silicone pad 8 is embedded in the receiving groove 46. The bottom surface of the anti-slip silicone pad 8 protrudes from the bottom surface of the lifting base 42. When the thermos cup is placed on the table, the anti-slip silicone pad 8 directly contacts the table surface. Its high coefficient of friction increases the friction between the bottom of the thermos cup and the placement surface, effectively preventing the thermos cup from sliding or tipping over on a smooth table surface, thus improving the stability of the thermos cup. The coefficient of friction between silicone and common table surface materials (such as aluminum / steel, wood, plywood, plastic, etc.) is usually above 0.6. At the same time, the receiving groove 46 embeds the anti-slip silicone pad 8 into the bottom of the lifting base 42, so that the anti-slip silicone pad 8 does not occupy additional space outside the bottom of the lifting base 42, does not affect the lifting height of the lifting base 42 on the end face of the base 4, and thus does not affect the gap space between the first vent 41 and the placement surface, achieving compatibility between the anti-slip function and the ventilation function.

[0043] In some embodiments, the width of the breathable interlayer 3 is set to 3-6 mm to form an air insulation layer, which serves as both an insulating air layer and a channel for gas exchange.

[0044] It should be noted that setting the width of the breathable interlayer 3 to 3mm to 6mm is based on a comprehensive optimization consideration of gas flow efficiency and heat preservation performance. When the width of the breathable interlayer 3 is less than 3mm, the gas flow cross-sectional area is too small, the flow resistance increases significantly, the gas exchange efficiency between the outer wall of the purple clay inner liner 1 and the outside air decreases, and the purple clay double-pore structure cannot fully perform its "breathing" function; at the same time, the gap that is too narrow is easily blocked by dust or condensation film, causing the breathability function to fail. When the width of the breathable interlayer 3 is greater than 6mm, although the gas flow is smoother, the excessively thick air layer will aggravate the heat convection inside the interlayer, which will accelerate heat loss and weaken the heat preservation effect; at the same time, the excessively wide interlayer will increase the overall outer diameter of the thermos cup, affecting the grip and portability. This invention controls the width of the breathable interlayer 3 within the range of 3mm to 6mm. Within this width, the gas flow resistance is moderate, allowing for sufficient gas exchange between the outer wall of the purple clay inner liner 1 and the air in the interlayer. This effectively utilizes the breathability of the purple clay's double-pore structure. Simultaneously, the air in the interlayer forms a stable air insulation layer, leveraging the low thermal conductivity of air (approximately 0.026 W / (m·K)) to provide excellent heat insulation. Combined with the inherent heat storage properties of the purple clay material, this achieves a synergistic balance between breathability and heat preservation. Furthermore, this width range ensures a moderate overall outer diameter for the thermos, meeting ergonomic requirements for comfortable handling and balancing usability with a compact structure.
