Description

Technical Field

[0001] This disclosure relates to the technical field of coffee tools, and in particular to a coffee moka pot and coffee machine. Background Technology

[0002] The Moka pot, a traditional tool for preparing Italian coffee, uses bottom heating to generate steam pressure that forces hot water through a layer of coffee grounds, achieving highly efficient extraction. In recent years, as Italian coffee has gained popularity, the Moka pot has also become a market favorite. In response, many manufacturers have developed their own Moka pots to cater to this growing demand.

[0003] For example, Chinese patent document CN 209219978U discloses a composite moka coffee maker, including an upper seat, a powder hopper, and a lower seat. The powder hopper is placed inside the lower seat, and a lower seat screw neck is provided at the top of the lower seat. A bottom screw neck is provided at the bottom opening of the upper seat. The upper seat and the lower seat are connected as one unit through the bottom screw neck and the lower seat screw neck. The powder hopper includes a funnel and a filter screen provided at the top of the funnel. The bottom of the lower seat protrudes from the circumference to the center to form an inverted bucket. An internal hydraulic valve is provided at the top of the inverted bucket, and a bottom pressure relief valve is provided on the side wall of the lower seat in conjunction with the internal hydraulic valve.

[0004] The aforementioned moka pot features a double pressure safety system, which enhances the brewing temperature after the siphon is activated, resulting in higher temperatures and water pressure within the siphon chamber, leading to a more concentrated coffee. However, while the double pressure safety system increases the internal temperature of the moka pot, it also increases the internal pressure, causing the liquid inside to rise. This particular moka pot only uses a pressure relief valve to release pressure in the lower chamber. As the pressure gradually increases, leakage can easily occur, causing liquid to overflow from the lower chamber, posing a safety hazard of burns and affecting the normal use of the moka pot.

[0005] Therefore, it is urgent to achieve a breakthrough in the sealing performance and safety of Moka pots through structural optimization. Utility Model Content

[0006] The purpose of this disclosure is to overcome the shortcomings of the prior art and to provide a coffee moka pot and coffee machine that avoids the problem of liquid leakage caused by excessive internal pressure.

[0007] The purpose of this disclosure is achieved through the following technical solution:

[0008] A coffee moka pot includes a base pot, a powder carrier, and a top pot. The base pot is connected to the top pot. The base pot has a water boiling chamber. The powder carrier is disposed in the water boiling chamber and is used to hold coffee powder. The powder carrier has a steam channel. The water boiling chamber is connected to the steam channel. The top pot has a groove with a protruding liquid column forming a liquid channel. The groove, the liquid channel, the steam channel, and the water boiling chamber are sequentially connected.

[0009] The coffee moka pot also includes a pressure relief component and a copper-based thermally conductive sealing component. The outer peripheral wall of the bottom pot has an installation cavity. The copper-based thermally conductive sealing component has a through hole, which is connected to the installation cavity and the water boiling cavity respectively. The pressure relief component passes through the through hole and is connected to the installation cavity, so that the pressure relief component is sealed to the outer peripheral wall of the bottom pot.

[0010] In one embodiment, the pressure relief element is detachably connected to the mounting cavity.

[0011] In one embodiment, the end of the pressure relief component is provided with a connecting portion, which is threaded through a hole and connected to the peripheral wall of the mounting cavity.

[0012] In one embodiment, the copper-based thermally conductive seal includes a metal thermally conductive substrate and a high-temperature resistant sealing layer covering the surface of the metal thermally conductive substrate. The through hole penetrates the metal thermally conductive substrate and the high-temperature resistant sealing layer, and the high-temperature resistant sealing layer is press-fitted to the outer peripheral wall of the bottom pot.

[0013] In one embodiment, the copper-based thermally conductive seal is a ring-shaped structure.

[0014] In one embodiment, the pressure relief component is provided with an annular boss, which is connected to one end of the connecting portion and fits against the end face of the copper-based thermally conductive seal.

[0015] In one embodiment, the pressure relief component is further provided with a screwing part, which is located on the side of the annular boss away from the copper-based thermally conductive seal, and the screwing part is connected to the copper-based thermally conductive seal.

[0016] In one embodiment, the coffee moka pot further includes a water distribution mesh, and a boss is provided at one end of the powder carrier near the top pot, with the water distribution mesh welded to the end face of the boss.

[0017] In one embodiment, the upper pot also includes an upper pot body and a handle. The handle is connected to the outer periphery of the upper pot body, and the outer peripheral wall of the handle is provided with a plurality of grooves, which are spaced apart on the outer peripheral wall of the handle.

[0018] A coffee machine comprising the coffee moka pot described in any of the above embodiments.

[0019] Compared with the prior art, this disclosure has at least the following advantages:

[0020] The coffee grounds are connected to the top pot via a base pot, which has a water boiling chamber. The coffee grounds carrier is placed inside the water boiling chamber and is connected to the inner cavity of the base pot by a snap-fit ​​mechanism. The coffee grounds carrier has a steam channel, while the top pot has a groove with a liquid passage. The liquid passage, the steam channel, and the water boiling chamber are connected sequentially from top to bottom. When coffee grounds are loaded into the coffee grounds carrier, the liquid in the base pot is heated to a predetermined temperature and turns into steam. The steam pressure pushes the steam into the steam channel, where it is then extracted by the coffee grounds and flows into the inner cavity of the top pot through the liquid passage. During the boiling process, the external heat source heats the water in the boiling chamber, increasing the internal pressure. An installation cavity is provided on the outer wall of the kettle, and a through hole is provided in the copper-based thermally conductive seal, connecting the through hole to the installation cavity and the boiling chamber. A pressure relief component passes through the through hole and connects to the installation cavity. Because the copper-based thermally conductive seal ensures that the internal pressure of the kettle increases due to temperature rise during heating, the copper-based thermally conductive seal is placed on the outer wall of the kettle. The pressure relief component passes through the through hole of the copper-based thermally conductive seal and connects to the installation cavity. This prevents liquid from leaking from the installation cavity to the outer wall of the kettle when the pressure in the boiling chamber becomes too high. The pressure relief component is connected to the installation cavity, and the installation cavity and the boiling chamber are interconnected, ensuring that the pressure in the boiling chamber can be released when the kettle is heated again. By installing copper-based thermally conductive seals and pressure relief components on the outer perimeter of the base, leakage due to excessive pressure is avoided, preventing liquid from overflowing from the base and causing safety issues or affecting the normal use of the Moka pot.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0030] like Figures 1 to 3As shown, a coffee moka pot 10 according to an embodiment includes a base pot 100, a powder carrier 200, an upper pot 300, a pressure relief component 400, and a copper-based thermally conductive sealing component 500. The base pot 100 is connected to the upper pot 300. The base pot 100 has a water boiling chamber 110. The powder carrier 200 is disposed in the water boiling chamber 110 and is used to load coffee powder. The powder carrier 200 has a steam channel 210. The water boiling chamber 110 is connected to the steam channel 210. The upper pot 300 has a groove 310. The groove 310 has a protruding liquid column 350. The liquid column 350 forms a liquid channel 320. The groove 310, the liquid channel 320, the steam channel 210, and the water boiling chamber 110 are connected in sequence.

[0031] The outer peripheral wall of the bottom pot 100 is provided with an installation cavity 120. The copper-based thermally conductive sealing member 500 is provided with a through hole 510. The through hole 510 is connected to the installation cavity 120 and the boiling water cavity 110 respectively. The pressure relief member 400 passes through the through hole 510 and is connected to the installation cavity 120, so that the pressure relief member 400 is sealed to the outer peripheral wall of the bottom pot 100.

[0032] In this embodiment, a bottom pot 100 is connected to an upper pot 300, and the bottom pot 100 has a water boiling chamber 110. A powder carrier 200 is disposed within the water boiling chamber 110 and is connected to the inner cavity of the bottom pot 100 via a snap-fit ​​connection. The powder carrier 200 has a steam channel 210. The upper pot 300 has a groove 310, within which a liquid-passing column 350 protrudes, and within the liquid-passing column 350 is a liquid-passing channel 320. This allows the liquid-passing channel 320, the steam channel 210, and the water boiling chamber 110 to be sequentially connected from top to bottom. When coffee powder is loaded into the powder carrier 200, the liquid in the bottom pot 100 is heated to a predetermined temperature, turning into steam. The steam pressure propels the steam into the steam channel 210, where it is then extracted by the coffee powder and flows into the inner cavity of the upper pot 300 through the liquid-passing channel 320. During the water boiling process, the external heat source heats the water in the boiling chamber 110, increasing the internal pressure. An installation cavity 120 is provided on the outer peripheral wall of the kettle 100, and a through hole 510 is provided in the copper-based thermally conductive seal 500, connecting the through hole 510 to the installation cavity 120 and the boiling chamber 110. The pressure relief component 400 passes through the through hole 510 and is connected to the installation cavity 120. The copper-based thermally conductive seal 500 ensures that the kettle 100 remains under pressure during heating as the temperature rises. This increases internal pressure. Therefore, a copper-based thermally conductive seal 500 is installed on the outer peripheral wall of the base pot 100. A pressure relief component 400 passes through the through-hole 510 of the copper-based thermally conductive seal 500 and connects to the mounting cavity 120. This prevents liquid from leaking from the mounting cavity 120 to the outer peripheral wall of the base pot 100 when the pressure in the boiling chamber 110 is excessive. The pressure relief component 400 is connected to the mounting cavity 120, and the mounting cavity 120 is connected to the boiling chamber 110, ensuring that the pressure in the boiling chamber 110 can be released when the base pot 100 is heated again. By installing the copper-based thermally conductive seal 500 and the pressure relief component 400 on the outer peripheral wall of the base pot 100, leakage due to excessive pressure is avoided, preventing liquid from overflowing from the base pot 100 and causing safety issues or affecting the normal use of the Moka pot.

[0033] like Figure 1 As shown, in one embodiment, the pressure relief component 400 is detachably connected to the mounting cavity 120. It is understood that the detachable connection of the pressure relief component 400 to the mounting cavity 120 prevents coffee residue and limescale from clogging the through-hole 510 and the mounting cavity 120, allowing for deep cleaning of the mounting cavity 120 by disassembling the pressure relief component 400. Simultaneously, by replacing pressure relief components 400 of different specifications through the detachable connection, the pressure relief threshold of the water boiling chamber 110 can be adjusted.

[0034] Combination Figure 1 and Figure 3 As shown, further, the end of the pressure relief component 400 is provided with a connecting portion 430, which is threaded through a through hole 510 and connected to the peripheral wall of the mounting cavity 120. It can be understood that by providing a connecting portion 430 at the end of the pressure relief component 400, and the outer peripheral wall of the connecting portion 430 having an external thread structure, while the peripheral wall of the mounting cavity 120 also has an internal thread structure, the external thread of the connecting portion 430 and the internal thread of the mounting cavity 120 are engaged to form a threaded connection, thereby threading the pressure relief component 400 onto the base vessel 100.

[0035] like Figure 1 As shown, in one embodiment, the copper-based thermally conductive seal 500 includes a metal thermally conductive substrate and a high-temperature resistant sealing layer covering the surface of the metal thermally conductive substrate. The through-hole 510 penetrates the metal thermally conductive substrate and the high-temperature resistant sealing layer, and the high-temperature resistant sealing layer is interference-fitted with the wall of the mounting cavity 120 of the bottom pot 100. In this embodiment, the metal thermally conductive substrate is made of a copper-based alloy material with high thermal conductivity, and its shape is adapted to the cross-sectional shape of the mounting cavity 120, for example, in the form of a circular or rectangular ring structure, to tightly fit the outer peripheral wall of the bottom pot 100. The inner sidewall of the metal thermally conductive substrate is adjacent to the cavity wall of the boiling chamber 110, which can quickly conduct heat from the external heat source of the bottom pot 100 to the water in the boiling chamber 110, improving heating efficiency. The high-temperature resistant sealing layer is preferably made of silicone rubber or polytetrafluoroethylene, and is laminated to the outer peripheral wall of the metal thermally conductive substrate by molding or coating processes, and can withstand high-temperature environments.

[0036] like Figure 3 As shown, in one embodiment, the copper-based thermally conductive seal 500 is a ring-shaped structure. It can be understood that by designing the copper-based thermally conductive seal 500 as a ring-shaped structure, the sealing performance of the pressure relief component 400 on the moka pot is enhanced, and the ring-shaped structure is more suitable for the structural design of the outer peripheral wall of the moka pot.

[0037] like Figure 3As shown, in one embodiment, the pressure relief component 400 is provided with an annular boss 410, which is connected to one end of the connecting portion 430 and fits against the end face of the copper-based thermally conductive seal 500. It can be understood that by providing the annular boss 410 in the pressure relief component 400, with the annular boss 410 close to the connecting portion 430 and its end face extending beyond the connecting portion 430, the annular boss 410 fits against the end face of the copper-based thermally conductive seal 500, thereby achieving a buffering effect between the pressure relief component 400 and the copper-based thermally conductive seal 500. When the pressure increases, it prevents the copper-based thermally conductive seal 500 from impacting the pressure relief valve and causing the pressure relief component 400 to move outward. Simultaneously, by providing the annular boss 410, wear and tear between the copper-based thermally conductive seal 500 and the pressure relief component 400 can be avoided.

[0038] like Figure 3 As shown, the pressure relief component 400 further includes a screwing part 420, which is located on the side of the annular boss 410 away from the copper-based thermally conductive seal 500. The screwing part 420 is connected to the copper-based thermally conductive seal 500. It can be understood that by providing the screwing part 420, the user can easily disassemble or install the pressure relief component 400 manually without the need for tools, thus improving ease of use. The outer peripheral wall of the screwing part 420 may be provided with anti-slip textures or angular structures to increase friction and prevent slippage during screwing.

[0039] Combination Figure 2 and Figure 3 As shown, in one embodiment, the coffee moka pot 10 further includes a water separator 600. A boss is provided at one end of the powder carrier 200 near the upper pot 300, and the outer periphery of the water separator 600 is welded to the end face of the boss. It can be understood that by providing a boss on the powder carrier 200 and welding the outer periphery of the water separator 600 to the boss, when water flows through the steam channel 210 to the liquid channel 320, the water separator 600 separates residue from the liquid, preventing coffee residue from flowing into the upper pot 300 along with the liquid.

[0040] like Figure 2As shown, the upper kettle 300 further includes an upper kettle body 330 and a handle 340. The handle 340 is connected to the outer periphery of the upper kettle body 330, and the outer peripheral wall of the handle 340 is provided with a plurality of anti-slip grooves 3410, which are spaced apart on the outer peripheral wall of the handle 340. It can be understood that by dividing the upper kettle 300 into the upper kettle body 330 and the handle 340, when the liquid extracts the coffee powder in the powder carrier 200 through the steam channel 210, it will flow to the liquid passage 320, and finally the coffee liquid will flow into the inner cavity of the upper kettle body 330. The upper body 330 and the handle 340 are welded together to form the upper kettle 300. The handle 340 has several anti-slip grooves 3410 on its outer peripheral wall near the upper body 330. These grooves increase friction when the user grips the handle 340, preventing slippage during use and improving safety. Simultaneously, the multiple spaced anti-slip grooves 3410 also distribute pressure on the user's hand to a certain extent, making the grip more comfortable.

[0041] This application also includes a coffee machine comprising the coffee moka pot 10 described in any of the above embodiments. It is understood that by using the coffee moka pot 10 in a coffee machine, and providing a copper-based heat-conducting seal 500 and a pressure relief component 400 on the outer peripheral wall of the bottom pot 100, leakage due to excessive pressure is avoided, preventing liquid from overflowing from the bottom pot 100 to the outside and causing safety issues or affecting the normal use of the moka pot.

[0042] Compared with the prior art, this disclosure has at least the following advantages:

[0043] The bottom pot 100 is connected to the top pot 300, and the bottom pot 100 has a water boiling chamber 110. The powder carrier 200 is placed in the water boiling chamber 110 and is connected to the inner cavity of the bottom pot 100 by a snap-fit. The powder carrier 200 has a steam channel 210, and the top pot 300 has a groove 310. A liquid passage 320 is provided in the groove 310, so that the liquid passage 320, the steam channel 210 and the water boiling chamber 110 are connected from top to bottom. When coffee powder is loaded into the powder carrier 200, the liquid in the bottom pot 100 is heated to a predetermined temperature and turns into water vapor. The steam pressure pushes the liquid into the steam channel 210, and then the coffee powder extracts the coffee liquid, which then flows into the inner cavity of the top pot 300 through the liquid passage 320. During the water boiling process, the external heat source heats the water in the boiling chamber 110, increasing the internal pressure. An installation cavity 120 is provided on the outer peripheral wall of the kettle 100, and a through hole 510 is provided in the copper-based thermally conductive seal 500, connecting the through hole 510 to the installation cavity 120 and the boiling chamber 110. The pressure relief component 400 passes through the through hole 510 and is connected to the installation cavity 120. The copper-based thermally conductive seal 500 ensures that the kettle 100 remains under pressure during heating as the temperature rises. This increases internal pressure. Therefore, a copper-based thermally conductive seal 500 is installed on the outer peripheral wall of the base pot 100. A pressure relief component 400 passes through the through-hole 510 of the copper-based thermally conductive seal 500 and connects to the mounting cavity 120. This prevents liquid from leaking from the mounting cavity 120 to the outer peripheral wall of the base pot 100 when the pressure in the boiling chamber 110 is excessive. The pressure relief component 400 is connected to the mounting cavity 120, and the mounting cavity 120 is connected to the boiling chamber 110, ensuring that the pressure in the boiling chamber 110 can be released when the base pot 100 is heated again. By installing the copper-based thermally conductive seal 500 and the pressure relief component 400 on the outer peripheral wall of the base pot 100, leakage due to excessive pressure is avoided, preventing liquid from overflowing from the base pot 100 and causing safety issues or affecting the normal use of the Moka pot.

[0044] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
