Description

Technical Field

[0001] This utility model relates to the field of moka pot technology, and more specifically, to a moka pot. Background Technology

[0002] The Moka pot is a powerful and practical home coffee brewing device. It heats water in the lower chamber, forcing it through coffee grounds under steam pressure to fully extract the flavor and aroma, which is then collected in the upper chamber as coffee liquid. With it, users can easily brew rich, flavorful coffee with an espresso-like base at home without complicated procedures.

[0003] In existing Moka pot designs, the upper pot, coffee grounds container, and lower pot are arranged sequentially from top to bottom. A first channel connects the lower pot to the bottom of the coffee grounds container; a second channel connects the top of the coffee grounds container to the upper pot. In operation, the lower pot holds water, and the coffee grounds container holds coffee powder. The water in the lower pot is then heated. As the temperature rises, the internal pressure of the lower pot gradually increases. Under this pressure, the water is forced through the first channel into the coffee grounds container to extract the coffee. The extracted coffee then flows through the second channel into the upper pot, ultimately yielding a drinkable coffee.

[0004] However, driven by the pressure in the lower chamber, the water flows too quickly through the coffee grounds container, preventing the coffee grounds from fully contacting the water and completing the extraction process. This results in the coffee's flavor compounds and aroma components not being fully released, leading to a weak flavor and unpleasant taste, indicating a significant problem with unsatisfactory extraction.

[0005] The purpose of this invention is to provide a moka pot that addresses the technical problems described in the background section.

[0006] The embodiments of this utility model are implemented as follows:

[0007] This application provides a moka pot, comprising: a moka pot body, including an upper pot body, a powder storage bowl, and a lower pot body sequentially from the top to the bottom of the pot, wherein the powder storage bowl is clamped and positioned by the upper pot body and the lower pot body, and the upper pot body and the lower pot body are detachably connected; wherein a first channel is provided between the lower pot body and the powder storage bowl, and a second channel is provided between the powder storage bowl and the upper pot body, wherein the port of the second channel away from the powder storage bowl is the coffee outlet; a pressure assembly, including a positioning rod, a pressure spring, a pressure block, and an annular gasket. The positioning rod is arranged along the axial direction of the second channel and can reciprocate along the axial direction of the second channel. The first end face and the second end face of the positioning rod are located on the inner and outer sides of the first channel, respectively. The pressure block is arranged on the first end face of the positioning rod and is used to seal with the coffee outlet. The pressure spring is sleeved on the positioning rod inside the second channel and is used to drive the positioning rod to move so that the pressure block seals the coffee outlet.

[0008] Furthermore, based on the aforementioned scheme, the first end face of the second channel is provided with an external threaded connector, and the port of the external threaded connector away from the second channel is threadedly fitted with a sealing head. The pressure block is slidably disposed inside the external threaded connector. The portion of the external threaded connector located between the sealing head and the second channel is provided with an opening for connecting the inner and outer spaces of the external threaded connector. When the pressure block slides to the position between the opening and the sealing head, the opening communicates with the coffee outlet. When the pressure block slides to the position between the opening and the coffee outlet, the opening disconnects from the coffee outlet.

[0009] Furthermore, based on the aforementioned scheme, the second end face of the positioning rod is fixed with a limiting piece by bolts, the pressure spring is detachably inserted on the positioning rod, and one end of the pressure spring is connected to the limiting piece, while the other end is connected to the side wall of the first channel; wherein, the pressure block and the positioning rod are detachably connected by threads.

[0010] Furthermore, based on the aforementioned scheme, the mouth and bottom of the powder storage bowl face the upper pot and the lower pot respectively, and the bottom of the powder storage bowl is provided with multiple water-permeable holes; wherein, the port of the second channel connecting the powder storage bowl is provided with a conical cylinder, the small diameter end of the conical cylinder is connected to the second channel, and the large diameter end of the conical cylinder is connected to the bottom of the powder storage bowl, and is simultaneously covered with multiple water-permeable holes.

[0011] Furthermore, based on the aforementioned solution, a filter screen can be detachably installed at the mouth of the powder storage bowl.

[0012] Furthermore, based on the aforementioned scheme, the upper pot body and the lower pot body are detachably connected by a threaded connection.

[0013] Furthermore, based on the aforementioned scheme, the lower body of the vessel is equipped with a pressure relief valve.

[0015] Compared with the prior art, the embodiments of this utility model have at least the following advantages or beneficial effects:

[0016] The moka pot disclosed in this application operates by using a pressure assembly to regulate the coffee extraction process. A positioning rod reciprocates axially along the second channel, and a pressure spring, fitted onto the positioning rod, provides elasticity, pushing the positioning rod to tightly seal the coffee outlet. When the moka pot is in operation, the lower chamber heats up, causing water to flow under pressure through the first channel into the coffee grounds container to extract the coffee powder. As the pressure gradually increases, when it overcomes the elasticity of the pressure spring, the positioning rod moves away from the coffee outlet, allowing the coffee to flow out. This design offers significant advantages: the pressure assembly effectively controls the flow rate of the coffee, preventing excessive water flow and ensuring sufficient contact between the coffee powder and water for a complete extraction process. This fully releases the flavor compounds and aroma components of the coffee, solving the problems of weak flavor and poor taste in existing technologies, and greatly improving extraction efficiency and coffee quality.

Detailed Implementation

[0025] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0026] Example

[0027] Please refer to Figures 1-6 This application provides a moka pot, comprising: a moka pot body 1, which includes an upper pot body 101, a powder storage bowl 102, and a lower pot body 103 sequentially from the top to the bottom of the pot. The powder storage bowl 102 is held and positioned by the upper pot body 101 and the lower pot body 103, and the upper pot body 101 and the lower pot body 103 are detachably connected. A first channel 14 is provided between the lower pot body 103 and the powder storage bowl 102, and a second channel 15 is provided between the powder storage bowl 102 and the upper pot body 101, with the port of the second channel 15 furthest from the powder storage bowl 102 serving as the coffee outlet. A pressure assembly includes a positioning rod 11 and a pressure spring 7. The pressure block 6 and the annular gasket 10 are provided. The positioning rod 11 is arranged along the axial direction of the second channel 15 and can reciprocate along the axial direction of the second channel 15. The first end face and the second end face of the positioning rod 11 are located on the inner and outer sides of the first channel 14, respectively. The pressure block 6 is arranged on the first end face of the positioning rod 11 and is used to seal with the coffee outlet. The pressure spring 7 is sleeved on the positioning rod 11 inside the second channel 15 and is used to drive the positioning rod 11 to move so that the pressure block 6 seals the coffee outlet. The annular gasket 10 is arranged on the pressure block 6 and is used to seal the contact position between the pressure block 6 and the coffee outlet.

[0028] The moka pot of this application operates on the principle of using a pressure component to regulate the coffee dispensing process. A positioning rod 11 can reciprocate along the axial direction of the second channel 15. A pressure spring 7 is fitted onto the positioning rod 11 and provides elasticity, pushing the positioning rod 11 to tightly seal the coffee outlet with the pressure block 6. When the moka pot is in operation, the lower pot body 103 heats up, causing water to enter the coffee powder container 102 through the first channel 14 under pressure to extract the coffee powder. As the pressure gradually increases, when the pressure overcomes the elasticity of the pressure spring 7, the positioning rod 11 moves away from the coffee outlet, allowing the coffee liquid to flow out. This design has significant advantages: the pressure component effectively controls the flow rate of the coffee liquid, preventing excessive water flow and ensuring sufficient contact between the coffee powder and water to complete the extraction process. This fully releases the flavor compounds and aroma components of the coffee, solving the problem of weak flavor and poor taste in existing technologies, and greatly improving the extraction effect and coffee quality.

[0029] In a preferred embodiment, the first end face of the second channel 15 is provided with an external threaded connector 8. The external threaded connector 8 is threadedly fitted with a sealing head 4 at the port away from the second channel 15. The pressure block 6 is slidably disposed inside the external threaded connector 8. The portion of the external threaded connector 8 located between the sealing head 4 and the second channel 15 is provided with an opening 9 for connecting the inner and outer spaces of the external threaded connector 8. When the pressure block 6 slides to the position between the opening 9 and the sealing head 4, the opening 9 communicates with the coffee outlet. When the pressure block 6 slides to the position between the opening 9 and the coffee outlet, the opening 9 disconnects from the coffee outlet.

[0030] In the above embodiment, the pressure block 6 is slidably disposed within the external threaded connector 8, which improves the stability of the pressure block 6 during operation. The threaded fit design between the external threaded connector 8 and the sealing head 4 not only facilitates installation and disassembly, but also allows for quick disassembly when maintenance or cleaning of the pressure block 6 or related components is required, thus improving the convenience of equipment maintenance.

[0031] Optionally, the outer surface of the sealing head 4 is provided with anti-slip texture to facilitate tightening or disassembling of the sealing head 4. There are four openings 9, arranged at intervals along the circumferential direction of the external threaded connector 8, resulting in better liquid discharge.

[0032] In a preferred embodiment, the second end face of the positioning rod 11 is fixed with a limiting piece 12 by bolts, and the pressure spring 7 is detachably mounted on the positioning rod 11. One end of the pressure spring 7 is connected to the limiting piece 12, and the other end is connected to the side wall of the first channel 14. The pressure block 6 and the positioning rod 11 are detachably connected by threads.

[0033] In the above embodiment, the limiting piece 12 provides a force-bearing point for the pressure spring 7. By removing the pressure block 6, the positioning rod 11 can be easily removed from the second end face of the second channel 15, thereby making the pressure spring 7 detachable and facilitating the cleaning of the pressure assembly.

[0034] In a preferred embodiment, the mouth and bottom of the powder storage bowl 102 face the upper pot body 101 and the lower pot body 103, respectively. The bottom of the powder storage bowl 102 is provided with a plurality of water-permeable holes. A conical cylinder 13 is provided at the port of the second channel 15 that connects to the powder storage bowl 102. The small-diameter end of the conical cylinder 13 is connected to the second channel 15, and the large-diameter end of the conical cylinder 13 is connected to the bottom of the powder storage bowl 102 and is covered with a plurality of water-permeable holes.

[0035] In the above embodiment, when hot water flows from bottom to top, multiple water-permeable holes provide a uniform penetration path for the hot water, enabling it to pass through the coffee powder in the powder storage bowl 102 comprehensively and evenly, avoiding the situation where local coffee powder is under-extracted or over-extracted due to uneven distribution of hot water.

[0036] Optionally, a placement area is provided at the spout of the lower body 103 for placing the powder storage bowl 102, which improves the space utilization of the moka pot and makes it practical.

[0037] As a preferred embodiment, a filter screen 5 is detachably provided at the mouth of the powder storage bowl 102.

[0038] In the above embodiment, the design of the filter plate 5 effectively prevents coffee residue from flowing into the upper pot 101 through the first channel 14, thus ensuring the purity of the final coffee liquid and improving the coffee drinking experience. Particularly noteworthy is the folded edge of the filter plate 5, which precisely overlaps the rim of the powder container 102. During the docking operation between the upper pot 101 and the lower pot 103, this folded edge is clamped and fixed, thereby positioning the filter plate 5. This design not only ensures that the filter plate 5 remains stable throughout the operation of the moka pot, effectively fulfilling its filtering function, but also greatly simplifies the installation process and enhances the overall structural stability.

[0039] In a preferred embodiment, the upper pot body 101 and the lower pot body 103 are detachably connected by a thread.

[0040] In the above embodiments, the threaded connection is simple and intuitive. Users can easily install and remove the pot by simply rotating it, without the need for complicated tools. This greatly saves time and effort for users who frequently use Moka pots to make coffee. In addition, the detachable design allows users to easily separate the upper and lower pot bodies 103 for thorough cleaning of every corner inside the pot, effectively preventing coffee residue and stains from remaining and ensuring the quality of coffee made each time.

[0041] As a preferred embodiment, the lower pot body 103 is provided with a pressure relief valve 2.

[0042] In the above embodiment, when the moka pot is working, the water in the lower body 103 is heated to generate steam, and the internal pressure continues to rise. The pressure relief valve 2 can monitor the pressure in real time. Once the pressure exceeds the safety threshold, it will automatically open to release the pressure, effectively avoiding serious safety accidents such as the lower body 103 bursting due to excessive pressure, and providing reliable safety protection for users.

[0043] As a preferred embodiment, the upper pot body 101 is provided with a handle 3 and a lid.

[0044] In the above embodiments, the handle 3 is ergonomically designed for easy gripping. Whether removing the upper pot 101 from the heating source after extraction or pouring coffee into a cup, it provides a stable and comfortable grip, preventing accidents caused by overheating of the upper pot 101 or inconvenient operation. The lid effectively prevents dust and other impurities from falling into the upper pot 101, keeping the coffee liquid clean. Moreover, during coffee extraction, it can maintain the temperature and pressure inside the upper pot 101 to a certain extent, helping the coffee liquid to better retain its aroma and flavor.
