[0002] With the fast pace of life and increasing demand for convenient beverages, tea makers have become widely used in the market. Tea makers are designed to provide users with a convenient and quick tea-making experience, with the identification and feeding control of tea capsules being key aspects.

[0003] In existing tea brewing machines, a dot matrix reader is typically used to identify tea capsules, allowing for adjustments to brewing parameters based on the type of capsule to produce a tea brew that suits the user's taste. However, the common sliding cover design of current tea brewing machines has certain drawbacks. Early models only had a touch switch at one end of the sliding cover. This design means that if the user forgets to close the cover after inserting a tea capsule, the dot matrix reader will remain active. This continuous operation consumes energy, leading to unnecessary waste. Furthermore, the prolonged operation causes the internal electronic components to overheat and age, significantly impacting the reader's lifespan, increasing maintenance costs and replacement frequency, and reducing the overall stability and reliability of the tea brewing machine. Therefore, this invention proposes a tea capsule feeding control device. Utility Model Content

[0004] The purpose of this invention is to address the problem in the background technology that existing tea brewing machines have a touch switch on only one end of the sliding cover. If the sliding cover is not closed after being opened, the dot matrix identifier will continue to work, resulting in wasted energy, component aging, shortened lifespan, increased maintenance costs, and reduced equipment stability and reliability. This invention proposes a tea capsule feeding control device.

[0034] Example

[0035] like Figure 1 and Figure 2As shown, this utility model proposes a tea capsule feeding control device, including a housing 1. The housing 1, as the main load-bearing structure of the entire system, is made of high-strength and corrosion-resistant engineering plastic material. It not only provides a stable and precisely fitted installation space for the internal components but also possesses excellent heat insulation and dustproof performance, effectively protecting the internal components from external environmental temperature fluctuations, dust particles, and other interference, ensuring long-term stable operation of the system. A feeding cover 11 is installed on the housing 1. The feeding cover 11 features a convenient opening design, allowing tea capsules to be smoothly placed into the housing 1 after opening. An internal guide structure guides the tea capsules to fall precisely into the housing 1, quickly and accurately preparing the raw materials for brewing. An installation groove 12 is provided on the top of the housing 1 corresponding to the position of the feeding cover 11, and the feeding cover 11 is slidably connected to the installation groove 12. The housing 1 contains a tea capsule brewing system 13 and a waste capsule container 14. The tea capsule brewing system 13 integrates a precise water flow regulation module. Through a precise flow control valve, it can accurately adjust the water flow rate and pressure according to the selected brewing mode. By using specific pressure and water temperature, the essence of tea leaves in the tea capsules is fully extracted, delivering tea with stable quality and mellow taste. The waste capsule compartment 14 is used to store used tea capsules. Its large-capacity design facilitates centralized processing, reduces the hassle of frequent cleaning, and maintains a clean brewing environment.

[0036] Furthermore, the aforementioned control device also includes a water tank 2 located on one side of the housing 1. The water tank 2 is made of food-grade material and is used to store water for brewing. Its reasonable capacity design meets the user's daily needs for multiple brewing sessions.

[0037] Furthermore, the aforementioned control device also includes a dot matrix identifier 3 installed in the housing 1, located below the mounting slot 12. The dot matrix identifier 3 is used to identify tea capsules so that the brewing parameters can be adjusted according to different types of tea capsules, thereby brewing tea that suits the user's taste.

[0038] For details, please refer to Figure 3 The aforementioned control device includes pressure sensors 5 disposed on both sides of the mounting groove 12. The pressure sensors 5 are used to identify the position information of the feed cover 11, and the two sets of pressure sensors 5 are used to detect whether the feed cover 11 is in an open or closed state. A positioning plate 51 is installed on the side of the pressure sensor 5 away from the extrusion plate 48. The positioning plate 51 is fixedly connected to the inner wall of the housing 1, and the position of the pressure sensor 5 is fixed by the positioning plate 51.

[0039] Among them, such as Figures 3 to 7As shown, the control device includes two sets of buffer mechanisms 4 installed on both sides of the mounting groove 12. The buffer mechanisms 4 are used to trigger the pressure sensor 5 when the feed cover 11 is opened or closed. The buffer mechanism 4 includes a fixing plate 41 disposed on the side of the mounting groove 12. The fixing plate 41 is fixedly connected to the inner wall of the housing 1, and the position of the fixing plate 41 is fixed. Two sets of limiting rods 42 are slidably connected in the fixing plate 41. The two sets of limiting rods 42 are fixedly connected to the mounting plate 43 at the end near the mounting groove 12. The mounting plate 43 moves smoothly under the limiting action of the limiting rods 42. A moving block 44 is installed on the side of the mounting plate 43 near the mounting groove 12. The moving block 44 is slidably connected in the mounting groove 12. The moving block 44 moves synchronously and smoothly with the mounting plate 43. After the feed cover 11 is opened or closed, one set of moving blocks 44 is squeezed. Two sets of limiting rods 42 are fixedly connected to a movable plate 45 at their ends away from the mounting plate 43. When the movable block 44 moves, it drives the movable plate 45 to move synchronously through the limiting rods 42 and the mounting plate 43. A first spring 46 is fitted around the outer ring of each of the multiple sets of limiting rods 42. The first spring 46 is located between the fixed plate 41 and the mounting plate 43. The first spring 46 is used to release the elastic force to drive the movable block 44 closer to the feed cover 11. At the same time, the movable plate 45 prevents the first spring 46 from driving the limiting rods 42 to detach from the fixed plate 41. Two sets of moving rods 47 are slidably connected to the moving plate 45. These two sets of moving rods 47 are symmetrically arranged on both sides of the fixed plate 41. A pressing plate 48 is connected to both sets of moving rods 47. The pressing plate 48 is located on the side of the fixed plate 41 away from the mounting groove 12. A pressure sensor 5 is located on the side of the pressing plate 48 away from the fixed plate 41. The two sets of moving rods 47 move synchronously, causing the pressing plate 48 to move. The movement of the pressing plate 48 triggers the pressure sensor 5, which detects whether the feed cover 11 is open or closed. A limiting plate 49 is fixedly connected to the end of the moving rod 47 near the mounting groove 12. The limiting plate 49 prevents the moving rod 47 from detaching from the moving plate 45. A second spring 410 is fitted around the outer ring of the moving rod 47. The second spring 410 is positioned between the moving plate 45 and the pressing plate 48. When the moving plate 45 moves towards the pressure sensor 5, it compresses the second spring 410, releasing its elastic force to move the pressing plate 48 and the moving rod 47. A rubber sleeve 411 is slidably connected to the moving rod 47. The rubber sleeve 411 is positioned on the side of the pressing plate 48 away from the fixed plate 41. The rubber sleeve 411 and the moving rod 47 are interference-fitted. The design of the rubber sleeve 411 slows down the movement speed of the moving rod 47, preventing the pressing plate 48 from directly impacting the detection end of the pressure sensor 5 and damaging it. A fixing seat 412 is installed on the outer side of the rubber sleeve 411. The fixing seat 412 is fixedly connected to the inner ring of the housing 1, fixing the position of the rubber sleeve 411.

[0040] A display screen 15 is installed on the outside of the housing 1. The tea capsule brewing system 13, the dot matrix reader 3, and the pressure sensor 5 are all electrically connected to the display screen 15. The display screen 15 adopts advanced touch technology, with high resolution and high contrast, providing a clear and intuitive display. It is used by the user to operate the brewing process, such as selecting brewing modes like green tea, black tea, and dark tea, which correspond to different water temperatures, water flow parameters, and adjusting water temperature and volume. Simultaneously, it displays brewing information in real time, including the brewing progress shown as a dynamic progress bar and the remaining water volume accurate to the milliliter, allowing the user to fully monitor the brewing status. The display screen 15 also receives signals triggered by the two sets of pressure sensors 5. It powers the dot matrix reader 3 when the feed cover 11 changes from open to closed, and de-energizes the dot matrix reader 3 when the feed cover 11 is permanently closed or permanently open.

[0041] In this embodiment, initially, the feed cover 11 is in the closed state, a set of pressure sensors 5 is triggered, the display screen 15 recognizes that the feed cover 11 is in the closed state, the dot matrix identifier 3 is in the power-off state, the tea capsule brewing system 13 is in standby mode, the display screen 15 displays the standby interface, the water tank 2 stores a sufficient amount of brewing water, and the waste capsule compartment 14 is empty or contains a certain amount of used tea capsules.

[0042] The user opens the feed cover 11, which slides open along the mounting groove 12. When the feed cover 11 is fully open, it presses against the moving block 44 on one side of the mounting groove 12. The moving block 44 then drives the mounting plate 43 to press against the first spring 46. Simultaneously, the moving block 44 moves the limiting rod 42 via the mounting plate 43, which in turn moves the moving plate 45. As the moving plate 45 moves, due to the interference fit between the moving rod 47 and the rubber sleeve 411, the moving plate 45 presses against the second spring 410. The second spring 410 then releases its elastic force, causing the pressing plate 48 and the moving rod 47 to move. The pressing plate 48 presses against the pressure sensor 5, which detects the opening signal of the feed cover 11 and transmits this signal to the display screen 15. Upon receiving the signal, the display screen 15 de-energizes the dot matrix recognition device 3. When the user places the tea capsule into the housing 1 through the opening formed by the feed cover 11, the guide structure inside the feed cover 11 guides the tea capsule to fall precisely into the housing 1. The user closes the feed cover 11, which slides along the mounting groove 12 to close, simultaneously causing the tea capsule to move downwards past the dot matrix identifier 3. First, the first spring 46 in the buffer mechanism 4 releases its elasticity, resetting all structures. At this time, both pressure sensors 5 are in an untriggered state. The display screen 15 then powers on the dot matrix identifier 3 and begins operation to identify the tea capsule. When the feed cover 11 is fully closed, it presses against the moving block 44 in the other buffer mechanism 4, repeating the linkage process of the moving block 44, limit rod 42, moving plate 45, moving rod 47, and pressing plate 48. This triggers the pressure sensor 5 on the other side, which transmits a signal indicating that the feed cover 11 is closed to the display screen 15. Upon receiving the signal and confirming that the capsule has been identified and placed, the display screen 15 de-energizes the dot matrix identifier 3, stopping its operation and extending its lifespan.

[0043] The user selects a brewing mode, such as green tea, black tea, or dark tea, via the display screen 15. The display screen 15 then transmits the brewing mode signal to the tea capsule brewing system 13. The water flow regulation module in the tea capsule brewing system 13 precisely adjusts the water flow rate and pressure according to the selected brewing mode using a precision flow control valve. This specific pressure and water temperature are used to brew the tea capsules, fully extracting the tea essence and delivering a consistently high-quality, mellow-tasting tea. During the brewing process, the display screen 15 shows real-time brewing progress, remaining water level, and other brewing information.

[0044] After brewing, the used tea capsules fall into the waste capsule compartment 14 for storage. When the waste capsule compartment 14 reaches a certain capacity, the user can clean it to keep the brewing environment clean.

[0045] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
