Description

Technical Field

[0001] This utility model relates to the field of long-spouted kettles, specifically to a long-spouted kettle with a safety barrier. Background Technology

[0002] Long-spouted teapot tea ceremony is a traditional cultural form that integrates skill and aesthetics. The performance often involves highly difficult movements such as large tilts and waving motions. To ensure safety, existing long-spouted teapots used in performances are usually equipped with a lid at the top inlet to prevent hot water from splashing out when the pot is shaken.

[0003] However, this method of sealing, which relies on the lid, has inherent flaws. During vigorous performances, the lid may accidentally fall off due to incomplete fastening or severe impact. Once the lid falls off, the top inlet is completely open, and the hot water inside the kettle will splash out unimpeded due to inertia, easily scalding the performer and surrounding audience, posing a serious safety hazard.

[0004] Furthermore, the inner wall of the spout of the existing long-spouted teapot is not specially treated and has strong hydrophilicity. When the spout stops abruptly during a performance, the water remaining on the inner wall forms a water film due to capillary effect and surface tension, which easily forms a fine mist that sprays out.

[0005] At the same time, the teapot lacks an effective high-temperature warning mechanism. When performers are fully focused, if they need to temporarily let go of the handle or change their grip due to the need for the action, there is a risk of forgetting that the teapot is hot and taking their hands off the handle, thus touching the teapot and getting burned. Utility Model Content

[0006] To address the problems of easy leakage, easy splashing of water droplets, and lack of high temperature warning in existing technologies, this application provides a long-spouted kettle with a safety barrier.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows: A long-spouted kettle with a safety barrier includes a kettle body and a spout. The kettle body is also provided with a leak-proof structure, which includes a leak-proof cylinder and a leak-proof tube fixedly installed below the water inlet of the kettle body. The leak-proof cylinder is hollow inside, with a water inlet hole on the upper end face and a water outlet hole on the lower end face. The water outlet hole is connected to the leak-proof tube, which has at least one bend greater than 60°, and the end of the leak-proof tube points towards the inside of the kettle body.

[0008] Furthermore, the pot body is provided with a handle, the first part of the handle near the spout has an elliptical outline; the second part away from the spout has a flat outline.

[0009] Furthermore, the spout has a water outlet and an open end. The open end is fixedly connected to a position near the bottom of the kettle body and forms a 30-45° angle with the bottom of the kettle body. The water outlet is fixedly connected to the open end and has a flat end structure.

[0010] Furthermore, a heat insulation sheet is installed around the leak-proof cylinder inside the kettle body.

[0011] Furthermore, a filter screen is provided inside the opening.

[0012] Furthermore, the first part of the handle has an internal hollow structure with multiple through holes on its surface, and an infrared sensor is installed inside the hollow structure.

[0013] Furthermore, the interior of the water outlet is coated with a hydrophobic layer.

[0014] Furthermore, the bending structure of the leak-proof pipe is an L-shaped bend.

[0015] Furthermore, the bending structure of the leak-proof pipe is an S-shaped bend.

[0016] Furthermore, the bend structure of the leak-proof pipe is a U-shaped bend.

[0017] Beneficial effects: This invention features an active leak-proof mechanism that is independent of the kettle lid. Even in the extreme case of accidental lid detachment, the backflow path of the liquid inside the kettle is effectively blocked by the bend in the leak-proof tube, thus eliminating the safety hazard of hot water splashing. Furthermore, the hydrophobic layer of the layered structure on the inner wall of the spout greatly reduces the formation of residual water film during closing, preventing water spray and improving the viewing experience. The combination of an infrared sensor and a heat insulation sheet inside the handle provides dual safety protection through active warning and passive safeguards. Simultaneously, the optimized spout angle and flat-mouth structure, the ergonomic handle, and the filter screen significantly improve water flow control, grip comfort, and ease of use. Moreover, its simple structure and convenient operation make it suitable for industrial-scale promotion. Attached Figure Description

[0026] Example 1: like Figure 3 The figure illustrates the specific structure of a long-spouted kettle with a safety barrier according to the present invention, including a kettle body 1 and a spout 2. The kettle body 1 is also provided with a leak-proof structure 4. The leak-proof structure 4 includes a leak-proof cylinder 42 and a leak-proof tube 41 fixedly installed below the water inlet of the kettle body 1. The leak-proof cylinder 42 is hollow inside, with a water inlet hole on the upper end face and a water outlet hole on the lower end face. The water outlet hole is connected to the leak-proof tube 41. The leak-proof tube 41 has at least one bend greater than 60°, and the end of the leak-proof tube 41 points towards the inside of the kettle body 1.

[0027] Working principle and technical effects: The core of the leak-proof structure of this utility model lies in its unique water injection path design. A hollow leak-proof cylinder 42 is connected below the water inlet at the top of the kettle body. A leak-proof pipe 41 with a bend of more than 60° is provided at the bottom of the cylinder. The end of the leak-proof pipe 41 points into the kettle body 1. The safety barrier in the name of this utility model refers to this leak-proof structure.

[0028] During water filling, the water flows vertically downwards from the inlet, through the leak-proof cylinder 42 and the bent leak-proof pipe 41, finally flowing into the bottom of the pot. In the demonstration, when the pot 1 is tilted sharply or swung rapidly, even if the liquid surface inside the pot shakes violently, the obvious bend in the leak-proof pipe 41 prevents the liquid from smoothly rising back up along the original filling path to the top inlet and being flung out. This creates an effective physical barrier, disrupting the upward flow of the liquid due to inertia, thus achieving the purpose of preventing leakage.

[0029] By designing the water inlet channel as a pipe with bends, the liquid backflow path is blocked by physical structure, solving the safety problem of liquid splashing out from the top inlet and scalding performers or audience members if the lid falls off during vigorous movements of the long-spouted kettle. This improves the reliability and cleanliness of the performance. At the same time, the structure is integrally molded with no moving parts, making it sturdy and durable without affecting the aesthetics of the kettle. It also ensures leak-proof performance while having almost no maintenance costs.

[0030] Example 2: To achieve better technical results, such as Figure 1-3 As shown, this embodiment is a further improvement on the first embodiment. The main difference between the two embodiments is that the overall design of the long-spouted kettle has been optimized and a component indicating the risk of burns has been added.

[0031] In this embodiment, the long-spouted pot includes a pot body 1, a spout 2, and a leak-proof structure 4 disposed inside the pot body. As a conventional design, the pot body 1 in this embodiment still has a pot lid 11 on the water inlet. The leak-proof structure 4 is the key to ensuring that the liquid is controllable during the performance. It consists of a leak-proof cylinder 42 fixed directly below the water inlet of the pot body and a leak-proof pipe 41 connected thereto. The leak-proof cylinder 42 has a hollow cavity inside, with a water inlet at the top and a water outlet at the bottom. The leak-proof pipe 41 extends out from the water outlet and is designed with at least one bend greater than 60 degrees.

[0032] In this embodiment, as a preferred option, three designs are shown: a simple L-shaped bend, a more tortuous S-shaped bend, or a U-shaped bend that forms a loop.

[0033] In this embodiment, each of the three designs has different beneficial effects. First, the L-shaped bend design provides a direct and effective physical barrier through a sharp turn. When the performer swings the long-spouted kettle, the liquid inside will surge in the opposite direction of the movement due to inertia. If the liquid attempts to flow back through the leak-proof tube to the top inlet, its flow direction and kinetic energy will suddenly change when it passes through the right-angle bend of the L-shape. The liquid needs to overcome gravity and the turn to continue flowing to the inlet. This requirement largely consumes the liquid's inertial force, thus successfully blocking most of the liquid backflow caused by low-to-medium intensity shaking, providing reliable anti-splash protection for basic performance movements.

[0034] Secondly, the S-shaped bend design creates a labyrinth effect by forming continuous, opposite-direction bends in the flow channel. The returning liquid undergoes multi-stage kinetic energy dissipation and path obstruction. When the liquid flow generated by vigorous performance movements attempts to reach the inlet, its direction is forcibly changed at each S-shaped bend, resulting in a continuous and significant weakening of its kinetic energy. This continuous turning makes it difficult for the liquid to form a sufficiently powerful and coherent column to break through the entire winding path. Therefore, the S-shaped design can more effectively cope with high-intensity inertial impacts such as rapid rotation and sudden braking, further improving the reliability of preventing liquid from being thrown out of the inlet under complex movements.

[0035] Finally, there's the U-shaped bend design. This structure provides the highest level of protection against spillage. Its unique shape creates a natural retention area, ensuring that a portion of liquid always remains inside the leak-proof tube 41. This liquid forms a non-draining plug at the bottom of the U-bend. When the kettle experiences any shaking or tilting, this inherent plug acts as a powerful physical barrier. It not only effectively prevents liquid in the lower part of the kettle from rushing back to the inlet due to inertia, but its presence also increases the overall resistance of the liquid's backflow path. This design ensures that even if the kettle is inverted, the liquid remaining in the U-shaped tube immediately blocks the flow, fundamentally eliminating any possibility of liquid spilling out of the inlet.

[0036] In the above-mentioned preferred embodiment, the end of the leak-proof tube 41 points to the inside of the pot body 1, which is the same as the first embodiment.

[0037] In terms of the overall design of the teapot body 1, in order to improve the comfort, stability and performance artistry, a handle 3 is set on the teapot body. The handle 3 is ergonomically optimized. The first part of the outline near the spout 2 is oval, which makes it easy for the performer to hold it firmly with their fingers for precise pouring control. The second part of the outline away from the spout is flat, which makes it easy for the palm or other fingers to fit and hold it to perform large-scale movements such as flipping and lifting.

[0038] To further enhance functionality, the first part of the handle 3 is designed as a hollow structure with multiple through holes on the surface for infrared signals to pass through. An infrared sensor electronic module is installed inside the hollow cavity. The infrared sensor is configured to trigger a slight vibration when the infrared detector detects that the user's palm has left the body for time t1 (in this embodiment, time t1 is set to 3 seconds), to remind the user of the risk of burns and prevent the user from carelessly touching the edge of their palm with the body 1.

[0039] The spout 2 was also carefully designed. It consists of two parts: first, an open mouth 22 fixedly connected to the bottom of the pot body, forming an angle of 30°-45° with the bottom of the pot body. This angle is beneficial for guiding the liquid to flow smoothly into the spout when the pot body is tilted. Existing technology usually uses a higher angle of 60°. The inventor found in his long-term performance work that the long spout of the existing technology could not be well matched with the performance techniques due to the higher angle. Second, a water outlet 21 fixedly connected to the end of the open mouth 22. The end is a flat structure, which helps the water flow to gather and form a smooth and beautiful water line. Existing technology usually uses a pointed spout. Although the water line is thinner, firstly, the pointed spout is easy to poke customers, which is a safety hazard. Secondly, the water flow is smaller. Therefore, the inventor designed this kind of spout after long-term experimentation.

[0040] More specifically, a filter screen 23 is installed inside the open portion 22 to isolate impurities and prevent clogging of the slender spout. Furthermore, as a point of invention of this utility model, a hydrophobic layer is coated on the inner wall of the water outlet 21. Existing long-spouted kettles generally do not have this hydrophobic layer. Since long-spouted kettles are usually made of copper, even if the performer controls them properly during a performance, the audience can still feel a fine mist spraying on their faces. This is because when the spout stops and retracts rapidly during the closing action, the small amount of water remaining on the inner wall will violently scour the inner wall of the spout and splash due to inertia. At the same time, the water remaining inside the spout will spread into an unstable water film due to capillary effect and surface tension under the influence of airflow disturbance; this water film is easily sprayed out as fine mist droplets by subsequent spout movements.

[0041] To address this problem, the hydrophobic coating of this invention significantly reduces the surface energy of the inner wall, transforming the wettability of water from spreading and adhering to shrinking and sliding.

[0042] Specifically, it disrupts the adhesion of water, preventing residual water from spreading and forming a film on the inner wall. Instead, it quickly contracts and gathers into large droplets that easily slide back onto the body of the spout, thus minimizing the amount of water remaining on the inner wall of the spout. This mechanism cuts off the source of the water mist, effectively preventing water spray caused by airflow shearing the residual water film, both at the moment of closing the performance and during subsequent movements of the spout. This ensures a dry and elegant performance and enhances the audience's viewing experience.

[0043] In this embodiment, the hydrophobic layer coated on the inner wall of the water outlet 21 is specifically selected from the existing technology of Dashu brand M100 hydrophobic coating. This coating is a colorless, odorless, and non-toxic two-component material. As a very mature existing technology, the stability of this product has been proven by the market and has been used in the kitchenware field for a long time.

[0044] Admittedly, from a chemical perspective, the molecular structure of this type of hydrophobic layer will gradually degrade under prolonged exposure to high-temperature hot water and steam, leading to a weakening of the hydrophobic effect and even physical detachment. However, according to the inventor's actual tests, even under the harsh conditions simulating frequent brewing, the coating can maintain its full performance for about half an hour. Given that a single tea ceremony performance usually lasts less than 10 minutes, this durability is more than sufficient for the needs of a single performance or even multiple consecutive performances, ensuring that the spout maintains extremely low wettability throughout the performance. For professional occasions requiring long-term, high-intensity use, performers can easily avoid the performance degradation period of the coating by having multiple teapots to rotate, thus always ensuring the best spill-proof effect.

[0045] Finally, a heat insulation sheet 12 is installed around the leak-proof cylinder 42 inside the kettle body 1. The heat insulation material 12 can effectively block the conduction of heat to the outer wall of the kettle body, especially near the water inlet, reducing the risk of the performer being scalded when holding the kettle after filling it with water and improving the safety performance of the equipment.

[0046] In summary, the working process of this utility model's long-spouted kettle with a safety barrier is as follows: First, open the lid 11 on the top of the kettle body 1 and pour water into the inlet. The water flows vertically downwards, passing sequentially through the inlet hole at the upper end of the leak-proof cylinder 42, the cavity inside the leak-proof cylinder 42, and the outlet hole at the lower end, before entering the leak-proof tube 41. After flowing through the L-shaped, S-shaped, or U-shaped bends of the leak-proof tube 41, the end of the water flows towards the inside of the kettle body 1, guiding the water to the bottom of the kettle for storage.

[0047] At the start of the performance, the performer holds the handle 3. Its oval-shaped first part 31 allows for precise finger grip to control the pouring, while the flat second part 32 provides stable support for the palm to perform large movements. When the pot is tilted, the hot water inside flows smoothly out along the open spout 22, which is at a 30°-45° angle to the bottom of the pot, and is gathered into a smooth stream of water as it is poured out through the flat spout 21, which has a hydrophobic coating on its inner wall. The filter 23 inside the open spout 22 effectively isolates impurities such as tea leaves, preventing the spout from clogging.

[0048] During performances involving vigorous swinging, spinning, or sudden stops, the hot water inside the kettle shakes violently due to inertia. At this time, the leak-proof structure 4 plays a crucial role: the liquid attempting to flow back from the inlet is repeatedly altered and its kinetic energy is dissipated as it passes through the bend of the leak-proof pipe 41, thus effectively blocking the flow. Even if the lid 11 accidentally falls off, it can prevent hot water from splashing out and causing scalding.

[0049] During the moment when the spout stops abruptly during the performance, the hydrophobic layer on the inner wall of the water outlet 21 allows the residual water on it to quickly shrink into beads and slide back onto the body of the kettle 1, greatly reducing the phenomenon of water mist formed by the water film.

[0050] The heat insulation sheet 12 installed around the leak-proof cylinder 42 can reduce the conduction of heat to the pot wall; if the performer's palm leaves the first part 31 of the pot handle 3 for more than 3 seconds due to the need for the action, the infrared sensor inside will trigger a slight vibration, which will remind the performer to pay attention to the risk of high temperature, thus forming an active safety protection.

[0051] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
