Description

Technical Field

[0001] This utility model belongs to the field of coffee equipment technology, specifically relating to a portable moka pot with steam exhaust and splash prevention. Background Technology

[0002] A moka pot is a home coffee brewing device that uses steam pressure generated by heating water at the bottom to force hot water through a layer of coffee grounds to extract the coffee. It is popular because it produces a strong coffee with a strength between pour-over and espresso.

[0003] To improve portability, existing technologies have combined moka pots with electric heating devices. For example, Chinese patent document CN 118787234 A discloses a dual-power portable electric coffee cup. This solution includes a lid, upper cup body, filter funnel, lower cup body, base, lithium battery, and heating device. Heating at the bottom creates steam pressure in the water in the lower cup body. This pressure, combined with a siphon effect, forces the water through the filter funnel containing coffee grounds, ultimately delivering the extracted coffee to the upper cup body. The lid also has a vent to release steam. However, this solution still has the following drawbacks: while the direct-flow vent on the lid provides pressure relief, hot liquid can easily splash out during heating and boiling, posing a direct risk of burns, especially if the user is in close contact or misoperates. In addition, the straight-through structure also has obvious drawbacks in outdoor carrying scenarios. Bumps during movement or walking can easily cause the liquid inside the pot to spill out from the vent, which not only causes inconvenience to use, but also brings potential risk of burns.

[0004] Therefore, in view of the shortcomings of existing technology, there is an urgent need to provide a portable moka pot that can prevent steam from escaping and splashing. Summary of the Invention

[0005] In response to the problems in related technologies, this utility model proposes a portable moka pot with steam release and splash prevention to solve the safety and scalding hazards caused by accidental splashing of high-temperature liquid during the depressurization and venting process of existing products.

[0006] The technical solution of this utility model is implemented as follows: A portable moka pot with steam exhaust and splash prevention includes a lower cup body, a powder cup, and an upper cup body; the lower cup body has a lower cup cavity for containing a first fluid, and the upper part of the lower cup body has a lower cup opening, the lower cup cavity and the lower cup opening are interconnected; the powder cup enters the lower cup cavity through the lower cup opening; the upper cup body is detachably connected to the upper part of the lower cup body; the upper cup body has an upper cup cavity for containing a second fluid, and the upper part of the upper cup body has an upper cup opening, the upper cup cavity and the upper cup opening are interconnected; a cup lid is fitted to the upper cup opening, and the cup lid has several outlets communicating with the inside and outside. A steam outlet is provided; a liquid-blocking component is provided on the inner side of the steam outlet, the liquid-blocking component including a fixing frame, a liquid-blocking membrane, a support cap, and a liquid-blocking cover; the liquid-blocking membrane covers the steam outlet to prevent the second fluid from splashing out; the fixing frame is fixed to the periphery of the liquid-blocking membrane, the liquid-blocking cover is sleeved on the fixing frame, and the support cap is provided between the two to hold the liquid-blocking membrane against the steam outlet; the lower cup contains and heats the first fluid, and the generated steam pressure drives the heated first fluid into the powder cup for extraction, forming the second fluid which then enters the upper cup for storage, and the steam passes through the liquid-blocking component and is discharged from the steam outlet.

[0007] As a further improvement to the above solution, the liquid-blocking cover is provided with several first vent holes, and the support cap is provided with several second vent holes. Steam passes through the first vent holes and the second vent holes in sequence, passes through the liquid-blocking membrane, and is discharged from the steam outlet. By setting up the liquid-blocking component, while ensuring smooth steam discharge, it can reliably block and prevent the splashing of high-temperature liquid in the upper cup cavity. This ensures that the high-temperature steam must flow through the first vent holes on the liquid-blocking cover and the second vent holes on the support cap in sequence before being discharged, forming a tortuous steam channel, which significantly reduces the steam velocity and impact force.

[0008] As a further improvement to the above solution, the fixing frame is cylindrical and has at least one lug on its side wall; the inner side wall of the liquid blocking cover has a locking position corresponding to the lug, and the liquid blocking cover is fixedly connected to the lug of the fixing frame through the locking position.

[0009] As a further improvement to the above solution, the circumferential sidewall of the fixing frame is also provided with at least one guide part, each guide part extending along the axial direction of the fixing frame and having a guide slope at its starting end; the inner sidewall of the liquid-blocking cover is provided with a corresponding guide groove, which is engaged by the guide slope and correspondingly connected with the guide part. By providing guide parts with guide slopes on the fixing frame and cooperating with the guide grooves on the inner side of the liquid-blocking cover, smooth guidance and precise positioning can be achieved when the two are axially connected, effectively preventing misalignment and jamming. At the same time, in coordination with the lug locking position, it is easy for the components to be quickly and accurately fixed in place, greatly improving the convenience of assembly and the reliability of connection.

[0010] As a further improvement to the above solution, the fixing frame has a cylindrical cavity in the middle, and the support cap extends into the cylindrical cavity and is fitted into the cylindrical cavity; the opening of the liquid blocking cap faces upward and is sleeved on the fixing frame, restricting the support cap between the fixing frame and the liquid blocking cap.

[0011] As a further improvement to the above solution, the lower end of the support cap protrudes circumferentially to form a brim. When the support cap is confined between the fixing frame and the liquid-blocking cover, the lower end face of the brim abuts against the inner bottom of the liquid-blocking cover. By embedding the support cap into the cavity of the fixing frame and sealing it with the liquid-blocking cover, the support cap and the liquid-blocking membrane form an independent vapor buffer barrier within a limited space. This forces the discharged vapor to decelerate and meander within the cavity formed by the liquid-blocking cover and the support cap, effectively increasing the vapor flow resistance and preventing high-temperature liquid from being ejected and splashed with the vapor.

[0012] As a further improvement to the above solution, the bottom of the liquid-blocking cover is provided with the first vent hole, and the upper end of the support cap is provided with the second vent hole; the central axis of the support cap is hollow to form a venting channel, the first vent hole is connected to the second vent hole through the venting channel, and the first vent hole and the second vent hole are at least partially blocked in the vertical direction.

[0013] By partially blocking the first and second vent holes in the vertical direction, the steam is forced to change its flow direction in the venting channel of the support cap, effectively extending the steam discharge path and increasing the flow resistance, thus efficiently achieving steam buffering and ensuring safe use.

[0014] As a further improvement to the above solution, the lower cup body includes a heating base and a lower cup body connected sequentially from bottom to top;

[0015] The lower cup body has a lower cup cavity for containing the first fluid; the heating base has a shell, the interior of which is hollow to form a receiving cavity, and the receiving cavity is provided with an electronic control assembly, a heating module and a temperature measuring module;

[0016] The temperature sensing module's sensor head extends into the lower cup cavity; the heating module is positioned at the top of the accommodating cavity to heat the first fluid in the lower cup cavity; the electronic control assembly is electrically connected to both the heating module and the temperature sensing module, and the electronic control assembly stops or starts the heating module based on whether the temperature measured by the temperature sensing module exceeds a preset threshold. By setting an independent accommodating cavity inside the heating base housing, a centralized and isolated installation space is provided for core electrical components such as the electronic control assembly and the heating module. This not only effectively utilizes the structural space but also physically isolates the precision circuitry from the fluid channels, significantly improving the safety and stability of the components.

[0017] As a further improvement to the above solution, the temperature measurement module uses an NTC temperature sensor. Replacing the traditional mechanical temperature control switch with an NTC temperature sensor enables precise control of the extraction temperature, ensuring the optimal coffee flavor.

[0018] As a further improvement to the above solution, a storage battery is also provided in the housing cavity. The storage battery is connected to the electronic control assembly and is used to power the electronic control assembly, as well as the heating module and temperature measuring module. Integrating the storage battery into the housing cavity provides a stable built-in power supply for the electronic control system and heating module, allowing the Moka pot to completely break free from its dependence on a fixed power source and meet the needs of convenient coffee making on the go.

[0019] Beneficial effects:

[0020] By incorporating a liquid-blocking component inside the steam outlet of the cup lid, an effective barrier and buffer is formed against the emitted high-temperature steam. While ensuring smooth steam discharge, the liquid-blocking membrane reliably intercepts and prevents high-temperature liquid from splashing out of the upper cup cavity, eliminating the risk of burns caused by direct liquid spray and significantly improving safety. Furthermore, the liquid-blocking component also solves the problem of liquid leakage caused by bumps during transport. Its compact structure makes it particularly suitable for outdoor portable applications. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] In the description of this utility model, it should be understood that the term "several" means "at least one", and the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] Example:

[0040] like Figures 1-6As shown, this embodiment provides a portable moka pot with steam release and splash prevention, including a lower cup body 1, a powder cup 2, and an upper cup body 3; the lower cup body 1 has a lower cup cavity 11 for containing a first fluid, and the upper part of the lower cup body 1 has a lower cup opening 12, the lower cup cavity 11 and the lower cup opening 12 are interconnected; the powder cup 2 enters the lower cup cavity 11 through the lower cup opening 12; the upper part of the lower cup body 1 is detachably connected to the upper cup body 3 by a threaded connection or a snap-fit ​​connection; the upper cup body 3 has an upper cup cavity 31 for containing a second fluid, and the upper part of the upper cup body 3 has an upper cup opening 32, the upper cup cavity 31 and the upper cup opening 32 are interconnected; a cup lid 4 is connected to the upper cup opening 32 by a threaded or snap-fit ​​connection, and the center of the cup lid 4 has several steam outlets 41 that connect the inside and outside; in this embodiment, the steam outlets 41 are strip-shaped holes.

[0041] The inner side of the steam outlet 41 is provided with a liquid blocking component 5, which includes a fixing frame 51, a liquid blocking membrane 54, a support cap 52, and a liquid blocking cover 53. The liquid blocking membrane 54 covers the steam outlet 41 to prevent the second fluid from splashing out. The fixing frame 51 is fixed to the periphery of the liquid blocking membrane 54, and the liquid blocking cover 53 is sleeved on the fixing frame 51. The support cap 52 is provided between the two to press the liquid blocking membrane 54 against the steam outlet 41.

[0042] The lower cup body 1 contains and heats water as the first fluid. The steam pressure generated drives the heated first fluid into the powder cup 2 to contact and extract coffee powder, forming coffee liquid as the second fluid, which then enters the upper cup body 3 for storage. The steam passes through the liquid-blocking member 5, passes through the liquid-blocking membrane 54, and is discharged from the steam outlet 41.

[0043] The liquid-blocking cap 53 has several first vent holes 531 with a diameter of 1mm-3mm, and the support cap 52 has several second vent holes 521. Steam passes through the first vent holes 531 and the second vent holes 521 in sequence and is discharged from the steam outlet 41. The second vent holes 521 can be round holes with a diameter of 2mm-4mm, or they can be triangular or rectangular holes. By setting the liquid-blocking component 5, while ensuring smooth steam discharge, it can reliably block and prevent the high-temperature liquid in the upper cup cavity 31 from splashing with the steam. This ensures that the high-temperature steam must flow through the first vent holes 531 on the liquid-blocking cap 53 and the second vent holes 521 on the support cap 52 in sequence before being discharged, forming a tortuous steam channel, which significantly reduces the steam velocity and impact force. The liquid-blocking membrane 54 is a waterproof and breathable membrane. Its working principle lies in the selective permeability of the membrane to water vapor and liquid water: gaseous water molecules can pass through freely, while liquid water is blocked due to surface tension and larger particle size, thus effectively preventing liquid leakage. In industrial applications, this membrane often adopts a multi-layer composite structure, with a PE polymer breathable membrane as the core functional layer and a protective layer on the outside.

[0044] In this embodiment, the fixing frame 51 is cylindrical, and its side wall is provided with two symmetrically distributed lugs 511; the inner side wall of the liquid blocking cover 53 is provided with a locking position 532 corresponding to the lugs 511, and the liquid blocking cover 53 is fixedly connected to the lugs 511 of the fixing frame 51 through the locking position 532.

[0045] In this embodiment, the circumferential sidewall of the fixing frame 51 is also evenly distributed with two or four guide parts 512. Each guide part 512 extends along the axial direction of the fixing frame 51, and its starting end has an arc-shaped or conical guide slope 5121. The inner sidewall of the liquid-blocking cover 53 is provided with a corresponding guide groove 533. The guide groove 533 is inserted through the guide slope 5121 and is correspondingly connected with the guide part 512. By providing guide parts 512 with guide slopes 5121 on the fixing frame 51 and cooperating with the guide groove 533 on the inner side of the liquid-blocking cover 53, the two can achieve smooth guidance and precise positioning when axially docked, effectively preventing misalignment and jamming. At the same time, it works in conjunction with the lug 511 locking position 532 to facilitate the quick and accurate fixing of the components, greatly improving the convenience of assembly and the reliability of connection.

[0046] In this embodiment, the fixing frame 51 has a cylindrical cavity 513 in the middle, and the support cap 52 extends into the cylindrical cavity 513 and is engaged with the cylindrical cavity 513; the opening of the liquid blocking cap 53 faces upward and is sleeved on the fixing frame 51, restricting the support cap 52 between the fixing frame 51 and the liquid blocking cap 53.

[0047] In this embodiment, the lower end of the support cap 52 protrudes circumferentially to form a brim 523. When the support cap 52 is confined between the fixing frame 51 and the liquid-blocking cover 53, the lower end face of the brim 523 abuts against the inner bottom of the liquid-blocking cover 53. By embedding the support cap 52 into the cavity 513 of the fixing frame 51 and sealing it with the liquid-blocking cover 53, the support cap 52 and the liquid-blocking membrane 54 form an independent vapor buffer barrier within a limited space. This causes the discharged vapor to decelerate and meander within the cavity formed by the liquid-blocking cover 53 and the support cap 52, effectively increasing the vapor flow resistance and preventing high-temperature liquid from being ejected and splashed with the vapor.

[0048] In this embodiment, the bottom of the liquid-blocking cap 53 is provided with the first vent hole 531, and the upper end of the support cap 52 is provided with the second vent hole 521. The central axis of the support cap 52 is hollow to form a venting channel 522. The first vent hole 531 communicates with the second vent hole 521 through the venting channel 522, and the first vent hole 531 and the second vent hole 521 are staggered in the vertical direction to form partial area shielding to avoid direct venting. By making the first vent hole 531 and the second vent hole 521 partially shield each other in the vertical direction, the steam is forced to change its flow direction in the venting channel 522 of the support cap 52, effectively extending the steam discharge path and increasing the flow resistance, efficiently achieving steam buffering and ensuring the safety of use.

[0049] The lower cup body 1 includes a heating base 13 and a lower cup body 14 connected sequentially from bottom to top; the lower cup body 14 has a lower cup cavity 11 for containing the first fluid; the heating base 13 has a shell 131, the interior of the shell 131 is hollow to form a receiving cavity 132, and the receiving cavity 132 is provided with an electronic control assembly 6, a heating module 7 and a temperature measuring module 8;

[0050] The temperature sensing module 8's sensing head 81 extends into the lower cup cavity 11 via a threaded connection or press-fit method. The heating module 7, such as a heating plate or heating tube, is placed on top of the accommodating cavity 132 and is used to heat the first fluid in the lower cup cavity 11. The electrical control assembly 6 is electrically connected to the heating module 7 and the temperature sensing module 8 via wires or a flexible circuit board. The electrical control assembly 6 stops or starts the heating module 7 according to whether the temperature measured by the temperature sensing module 8 exceeds a preset threshold. By setting an independent accommodating cavity 132 inside the heating base 13 housing 131, a centralized and isolated installation space is provided for core electrical components such as the electrical control assembly 6 and the heating module 7. This not only effectively utilizes the structural space but also physically isolates the precision circuit from the fluid channel, significantly improving the safety and stability of the components.

[0051] In this embodiment, the temperature measurement module 8 uses an NTC temperature sensor. Replacing the traditional mechanical temperature control switch with an NTC temperature sensor enables precise control of the extraction temperature, ensuring the optimal coffee flavor.

[0052] In this embodiment, a storage battery 9 is also provided in the accommodating cavity 132. The storage battery 9 is connected to the electronic control assembly 6 and is used to supply power to the electronic control assembly 6, the heating module 7, and the temperature measuring module 8. Integrating the storage battery 9 into the accommodating cavity 132 provides a stable built-in power supply for the electronic control system and the heating module 7, allowing the Moka pot to completely break free from its dependence on a fixed power source and meet the needs of convenient coffee making on the go.

[0053] According to the above-described solution of this utility model, when the portable moka pot with steam-proof and splash-proof design is in actual operation, a first fluid (usually water) is first injected into the lower cup cavity 11 of the lower cup body 1, and then coffee powder is filled into the powder cup 2 to complete the assembly. After startup, the battery 9 in the accommodating cavity 132 supplies power to the system, and the heating module 7 begins to heat the lower cup cavity 11. During this process, the NTC temperature sensor of the temperature measuring module 8 monitors the water temperature in real time through the sensing head 81 that extends into the lower cup cavity 11, and transmits the data to the electronic control assembly 6.

[0054] When the water temperature reaches the preset ideal extraction threshold (e.g., 92℃-96℃), the electronic control assembly 6 controls the heating module 7 to adjust the power or temporarily stop heating to prevent the water temperature from being too high and causing over-extraction of the coffee. The steam pressure generated by the heat will push the hot water upward, penetrate the coffee powder in the powder cup 2 for full extraction, and the resulting second fluid (i.e., coffee liquid) will eventually enter the upper cup cavity 31 for storage.

[0055] Meanwhile, the high-pressure steam generated during the extraction process gathers at the top of the upper cup cavity 31 and flows towards the liquid-blocking component 5 of the cup lid 4. The steam first enters the first vent hole 531 at the bottom of the liquid-blocking lid 53, then changes direction through the vent channel 522 on the central axis of the support cap 52, passes through the second vent hole 521 at the upper end of the support cap 52, and finally exits from the steam outlet 41 through the liquid-blocking membrane 54, while the coffee liquid is blocked inside the liquid-blocking membrane 54. Because the first vent hole 531 and the second vent hole 521 are partially blocked in the vertical direction, the steam needs to change direction multiple times and overcome flow resistance when passing through, and its flow rate and impact force are significantly buffered. By setting the liquid-blocking component 5 inside the steam outlet 41 of the cup lid 4, an effective barrier and buffer is formed for the discharged high-temperature steam. While ensuring the smooth discharge of steam, the liquid-blocking membrane 54 can reliably block and prevent the high-temperature liquid in the upper cup cavity 31 from splashing, eliminating the risk of burns caused by direct liquid spray, and significantly improving the safety of use. In addition, the liquid-blocking component 5 solves the problem of liquid leakage caused by bumps during transport. Its compact structure makes it particularly suitable for portable applications.

Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
