Description

Technical Field

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

[0002] With people's growing love and pursuit of coffee culture, the Moka pot, as a classic coffee brewing device, has become widely popular. With its unique structure and convenient operation, the Moka pot can quickly extract a rich coffee, satisfying people's daily coffee needs.

[0003] Existing moka pots typically consist of an upper pot and a lower pot. The lower pot contains an inner pot for holding water and a heating element for heating the inner pot. During operation, the heating element heats the water in the inner pot, generating steam pressure that forces the hot water through the coffee grounds to extract the coffee. However, during the steam generation process, some water vapor enters the lower pot's containment chamber and seeps into the heating element, causing it to become damp and potentially leading to a short circuit, thus affecting the normal use of the moka pot.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] Regarding the aforementioned problem in existing moka pots where steam easily enters the lower chamber and permeates the heating element during the water heating process, causing moisture buildup and potentially leading to a short circuit, the technical solution adopted by this invention is as follows:

[0006] A moka pot with a sealing structure includes a moka pot body, which comprises an upper pot body and a lower pot body. The lower pot body has a receiving cavity, in which an inner pot body for holding water and communicating with the upper pot body is provided, and a heating component connected to the inner pot body is provided. A sealing element is provided between the inner pot body and the lower pot body to seal the gap between the inner pot body and the lower pot body to prevent steam from penetrating into the heating component.

[0007] Furthermore, the sealing element is a first elastic sealing ring.

[0008] Furthermore, the first elastic sealing ring includes an elastic mounting portion fitted onto the outer wall of the inner pot body.

[0009] Furthermore, the inner pot body is provided with a pressure relief valve that penetrates the lower pot body, and the first elastic sealing ring includes an elastic extension sleeved on the outer wall of the pressure relief valve.

[0010] Furthermore, the connection between the elastic mounting portion and the elastic extension portion is inclined and has rounded corners.

[0011] Furthermore, the lower body is provided with an installation port through which the pressure relief valve passes, the installation port including a limiting protrusion extending toward the inner body, and the elastic extension including an avoidance notch adapted to the limiting protrusion.

[0012] Furthermore, the elastic mounting portion and the elastic extension portion are integrally formed.

[0013] Furthermore, the inner pot body is provided with a mounting position for installing the pressure relief valve. The mounting position includes a limiting circular groove extending away from the lower pot body, and a second elastic sealing ring is provided on the limiting circular groove.

[0014] Furthermore, the thickness of the elastic extension is greater than the thickness of the elastic mounting portion.

[0015] Furthermore, the heating component is located at the bottom of the inner pot body.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention, by setting a seal between the inner pot body and the lower pot body, can effectively prevent water vapor from penetrating into the heating element, thereby avoiding short circuits caused by moisture in the heating element. This improves the safety and reliability of the moka pot and effectively solves the problem that in existing moka pots, water vapor generated during the water heating process easily enters the containment cavity of the lower pot body and penetrates into the heating element, causing the heating element to become damp and thus leading to a short circuit.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 8 The illustrated moka pot has a sealed structure and includes a moka pot body 1. The moka pot body 1 includes an upper pot body 2 and a lower pot body 3. The lower pot body 3 has a receiving cavity 31. The receiving cavity 31 has an inner pot body 4 for holding water and communicating with the upper pot body 2, and a heating component 5 connected to the inner pot body 4. A sealing element is provided between the inner pot body 4 and the lower pot body 3. The sealing element is used to seal the gap between the inner pot body 4 and the lower pot body 3 to prevent steam from penetrating into the heating component 5.

[0029] This invention, by setting a seal between the inner pot body and the lower pot body, can effectively prevent water vapor from penetrating into the heating element, thereby avoiding short circuits caused by moisture in the heating element. This improves the safety and reliability of the moka pot and effectively solves the problem that in existing moka pots, water vapor generated during the water heating process easily enters the containment cavity of the lower pot body and penetrates into the heating element, causing the heating element to become damp and thus leading to a short circuit.

[0030] Optionally, in some embodiments, the sealing element is a metal composite gasket, which is a stainless steel ring covered with polytetrafluoroethylene, thereby forming a combination of rigid support and flexible sealing. The metal composite gasket is disposed between the inner pot body 4 and the lower pot body 3 and is fixed by screwing or tightening pressure.

[0031] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the sealing element is an elastic sealing ring, which can be made of silicone or food-grade rubber material. The elastic sealing ring is fitted onto the outer wall of the inner pot body 4. When the inner pot body 4 is placed in the receiving cavity 31, the elastic sealing ring is interference-fitted with the inner wall of the lower pot body 3.

[0032] like Figures 1 to 8 The sealing element shown is the first elastic sealing ring 6;

[0033] Furthermore, the first elastic sealing ring 6 can fit tightly into the gap between the inner pot body 4 and the lower pot body 3 through its own elastic deformation, forming a reliable seal. Even under the action of high temperature and steam pressure, the first elastic sealing ring 6 can maintain a good sealing effect, which helps to prevent water vapor from penetrating into the heating component 5.

[0034] Furthermore, the first elastic sealing ring 6 has a certain degree of elasticity, which can adapt to the slight dimensional deviations or uneven surfaces between the inner pot body 4 and the lower pot body 3, so that the first elastic sealing ring 6 can more easily achieve sealing during installation and use without requiring very precise machining accuracy, thereby reducing production costs.

[0035] Furthermore, the first elastic sealing ring 6 is made of silicone or food-grade rubber material, which has good high temperature resistance and corrosion resistance, so that the first elastic sealing ring 6 can be used stably for a long time in the high temperature working environment of the Moka pot, and will not age or be damaged quickly due to high temperature or water vapor corrosion.

[0036] like Figures 1 to 8 The first elastic sealing ring 6 shown includes an elastic mounting portion 61 sleeved on the outer side wall of the inner pot body 4;

[0037] Furthermore, the elastic mounting part 61 can be directly fitted onto the outer wall of the inner pot body 4, providing a clear installation position for the first elastic sealing ring 6, making the installation process more accurate and efficient. The installer does not need to spend extra effort to adjust the position of the first elastic sealing ring 6, but only needs to fit it along the outer wall of the inner pot body 4, which reduces the error and time cost in the installation process and improves production efficiency.

[0038] Furthermore, the elastic mounting part 61 can fit tightly against the outer wall of the inner pot 4, and fill the tiny gap between the inner pot 4 and the lower pot 3 through its own elastic deformation, thereby achieving a good sealing effect. Even if there are slight dimensional deviations or uneven surfaces between the inner pot 4 and the lower pot 3, the elastic characteristics of the elastic mounting part 61 can adapt to these changes and ensure that the sealing performance is not affected.

[0039] Furthermore, when the moka pot needs to be cleaned or maintained, since the elastic mounting part 61 is fitted on the outer wall of the inner pot body 4, the user can relatively easily remove the first elastic sealing ring 6 from the inner pot body 4. This facilitates the separate cleaning of the first elastic sealing ring 6, removing any coffee stains, limescale, or other dirt that may be attached to it, ensuring the cleanliness and hygiene of the first elastic sealing ring 6, and extending its service life.

[0040] like Figures 1 to 8The inner pot body 4 shown is provided with a pressure relief valve 7 that penetrates the lower pot body 3. The first elastic sealing ring 6 includes an elastic extension 62 sleeved on the outer wall of the pressure relief valve 7.

[0041] Furthermore, the pressure relief valve 7 penetrates the lower pot body 3, and there is a gap at the connection between it and the lower pot body 3. Steam can easily leak from this point into the receiving cavity 31. The elastic extension 62 is tightly fitted onto the outer wall of the pressure relief valve 7, which can fill the gap and form a reliable seal. During the operation of the moka pot, the steam generated by the inner pot body 4 will not leak from the connection between the pressure relief valve 7 and the lower pot body 3 into the receiving cavity 31. Secondly, the elastic extension 62 and the elastic mounting part 61 cooperate with each other to seal the connection between the inner pot body 4 and the lower pot body 3 from multiple points, further enhancing the overall sealing performance of the moka pot and reducing the possibility of steam leakage.

[0042] Furthermore, during the use of the Moka pot, the pressure relief valve 7 may be subjected to vibration and impact. The elastic extension 62 has a certain degree of elasticity, which can play a role in buffering and shock absorption, reducing the impact of external forces on the pressure relief valve 7 and reducing the risk of damage.

[0043] Furthermore, the elastic extension 62 is fitted onto the outer wall of the pressure relief valve 7, which can be supported by the structure of the pressure relief valve 7 to make it more secure during use and less prone to loosening or displacement; secondly, during the heating process of the moka pot, some vibration may occur, and the elastic characteristics of the elastic extension 62 can effectively reduce the impact of vibration on the sealing performance, ensuring that the first elastic sealing ring 6 is always in a stable state during use.

[0044] like Figures 1 to 8 The connection between the elastic mounting portion 61 and the elastic extension portion 62 shown is inclined and has rounded corners;

[0045] Furthermore, the inclined and rounded connection provides a smoother transition, reduces stress concentration, and helps ensure that the elastic mounting part 61 and the elastic extension part 62 can deform evenly when under force, thereby better filling the tiny gaps between the inner pot body 4, the lower pot body 3, and the pressure relief valve 7, and further enhancing the sealing effect.

[0046] Furthermore, the inclined setting and rounded corners enable the elastic mounting part 61 and the elastic extension part 62 to be more evenly stressed, reducing the situation of excessive local stress, which helps to improve the stability of the first elastic sealing ring 6 in high temperature environment and prevent deformation or damage caused by excessive local stress.

[0047] Furthermore, the inclined setting and rounded corners make the connection between the elastic mounting part 61 and the elastic extension part 62 smoother, which helps to reduce friction and resistance during installation, making the installation process of the first elastic sealing ring 6 smoother, and allowing the user to more easily put the first elastic sealing ring 6 onto the inner pot body 4 and the pressure relief valve 7.

[0048] like Figures 1 to 8 The lower pot body 3 shown is provided with a mounting port 32 through which the pressure relief valve 7 passes. The mounting port 32 includes a limiting protrusion 321 extending toward the inner pot body 4. The elastic extension 62 includes an avoidance notch 621 adapted to the limiting protrusion 321.

[0049] Furthermore, the limiting protrusion 321 can limit the elastic extension 62, preventing the elastic extension 62 from shifting or loosening due to vibration or pressure changes during use. The clearance notch 621 is adapted to the limiting protrusion 321 so that the elastic extension 62 can fit tightly against the limiting protrusion 321, thereby ensuring that the first elastic sealing ring 6 remains stable during operation.

[0050] Furthermore, the cooperation between the clearance notch 621 and the limiting protrusion 321 ensures that the elastic extension 62 can be accurately positioned during installation, avoiding offset or misalignment during installation, so that the installation of the first elastic sealing ring 6 is more reliable and reduces the occurrence of steam penetration into the heating component 5 due to improper installation.

[0051] Furthermore, the cooperation between the limiting protrusion 321 and the clearance notch 621 ensures accurate installation and stable use of the elastic extension 62, reducing friction and wear between the elastic extension 62 and other components caused by improper installation or displacement. The elastic extension 62 can be evenly stressed during normal use, avoiding localized excessive wear, thereby extending the service life of the elastic extension 62 and reducing the frequency and cost of replacing the sealing ring.

[0052] like Figures 1 to 8 The elastic mounting portion 61 and the elastic extension portion 62 shown are integrally formed;

[0053] Furthermore, the one-piece molding eliminates the seam between the elastic mounting part 61 and the elastic extension part 62. When the moka pot is working, the inner pot body 4 and the pressure relief valve 7 will be subjected to certain pressure and temperature changes. If there are seams, steam may seep into the heating element from these seams. The one-piece molding design avoids this situation, ensuring the sealing integrity of the entire first elastic sealing ring 6. It can more effectively prevent steam from leaking from the connection between the inner pot body 4 and the lower pot body 3 and the installation location of the pressure relief valve 7, thereby ensuring the normal use of the moka pot.

[0054] Furthermore, the one-piece molded structure has higher overall strength and stability, and can better withstand high temperature and pressure changes, which helps to reduce the risk of seal failure caused by loosening or breakage at the connection.

[0055] Furthermore, the one-piece molding design eliminates the need for assembly steps between the elastic mounting portion 61 and the elastic extension portion 62, thereby simplifying the manufacturing process and reducing production costs.

[0056] like Figures 1 to 8 The inner pot body 4 shown is provided with a mounting position 8 for installing the pressure relief valve 7. The mounting position 8 includes a limiting circular groove 81 extending away from the lower pot body 3. The limiting circular groove 81 is provided with a second elastic sealing ring 82.

[0057] Furthermore, the limiting groove 81 extends away from the lower pot body 3, forming a clear installation reference surface, which helps to ensure the installation position of the pressure relief valve 7 and avoid sealing failure due to assembly deviation; secondly, the second elastic sealing ring 82 is interference-fitted with the limiting groove 81, which can provide continuous radial clamping force, so that the pressure relief valve 7 will not loosen even when the moka pot is handled or heated and vibrated.

[0058] Furthermore, by setting a second elastic sealing ring 82 on the limiting groove 81, a double sealing structure is formed, which can effectively prevent water vapor from leaking from the gap between the pressure relief valve 7 and the inner pot body 4 to the heating component 5, thereby further improving the sealing performance.

[0059] Furthermore, the second elastic sealing ring 82 can play a role in buffering and shock absorption, reducing direct friction and collision between the pressure relief valve 7 and the inner pot body 4. During the use of the moka pot, the pressure relief valve 7 will frequently open and close. Without the protection of the second elastic sealing ring 82, the friction between the parts will lead to increased wear and shorten the service life. The presence of the second elastic sealing ring 82 effectively reduces this wear and extends the service life of the pressure relief valve 7 and the inner pot body 4.

[0060] like Figures 1 to 8 The thickness of the elastic extension 62 shown is greater than the thickness of the elastic mounting portion 61;

[0061] Furthermore, the elastic extension 62 is located at the pressure relief valve 7 installation location, which faces greater pressure and steam impact when the Moka pot is working. The thicker elastic extension 62 can withstand greater pressure and is not easily deformed, thereby better filling the gaps in these parts and preventing steam from penetrating into the heating element 5.

[0062] Furthermore, the thicker elastic extension 62 has a stronger elastic recovery capability. When it comes into contact with components such as the mounting port 32 of the lower pot body 3 or the pressure relief valve 7, it can better fit the surface of these components. Even if there are some unevenness or minor defects on the surface, it can compensate for them through its own elastic deformation, further improving the reliability of the seal.

[0063] Furthermore, the thicker elastic extension 62 can better resist material fatigue and reduce the damage to the seal ring caused by long-term use. By increasing the thickness, the service life of the seal ring can be extended and the replacement frequency can be reduced.

[0064] like Figures 1 to 8 The heating component 5 shown is located at the bottom of the inner pot body 4;

[0065] Furthermore, placing the heating element 5 at the bottom of the inner pot body 4 can better protect the heating element 5 from direct contact with water vapor, reduce the risk of the heating element 5 becoming damp and short-circuiting due to water vapor penetration, and improve the safety of the product.

[0066] Furthermore, the heating component 5 is placed at the bottom of the inner pot body 4. Bottom heating ensures that heat is evenly transferred from the bottom up, making the water in the inner pot body 4 heated more evenly, thereby avoiding the problem of local overheating or uneven heating, which is conducive to improving the coffee brewing effect.

[0067] Furthermore, installing the heating element 5 at the bottom of the inner pot body 4 makes the overall structure of the moka pot more compact, and the bottom space is more regular and easier to utilize. Placing the heating element 5 here will not increase the horizontal or vertical dimensions of the moka pot, which is conducive to the miniaturization and portability of the product.

[0068] The implementation method of Example 1 is as follows:

[0069] A moka pot with a sealed structure includes a moka pot body 1, which includes an upper pot body 2 and a lower pot body 3. The lower pot body 3 has a receiving cavity 31, and the receiving cavity 31 has an inner pot body 4 for holding water and communicating with the upper pot body 2, and a heating component 5 connected to the inner pot body 4. A sealing element is provided between the inner pot body 4 and the lower pot body 3 to seal the gap between the inner pot body 4 and the lower pot body 3 to prevent steam from penetrating into the heating component 5.

[0070] This invention, by setting a seal between the inner pot body and the lower pot body, can effectively prevent water vapor from penetrating into the heating element, thereby avoiding short circuits caused by moisture in the heating element. This improves the safety and reliability of the moka pot and effectively solves the problem that in existing moka pots, water vapor generated during the water heating process easily enters the containment cavity of the lower pot body and penetrates into the heating element, causing the heating element to become damp and thus leading to a short circuit.
