[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] like Figures 1 to 11 The pressurization mechanism shown includes a pressurization mechanism 2 sealed to a liquid outlet pipe 1. The pressurization mechanism 2 includes a liquid outlet component 21 detachably connected to the liquid outlet pipe 1 and an elastic pressurization component 22 that is interference-fitted with the liquid outlet component 21. The liquid outlet component 21 is provided with a liquid outlet channel 211. The elastic pressurization component 22 is provided with a liquid inlet 221 and a liquid outlet 222 that can undergo elastic deformation. The liquid inlet 221 communicates with the liquid outlet channel 211 through the liquid outlet 222. The liquid outlet 222 expands as the pressure increases and contracts as the pressure decreases, so that liquid can enter the liquid outlet channel 211 through the liquid outlet 222.

[0032] This invention features a liquid outlet and an elastic pressure-boosting component that is interference-fitted with the liquid outlet. The elastic pressure-boosting component is installed on the liquid outlet pipe through the liquid outlet. When the internal pressure increases, the liquid outlet on the elastic pressure-boosting component undergoes elastic deformation and expands. When the internal pressure decreases, the liquid outlet returns to its elastic deformation and contracts. When the user needs to clean the pressure-boosting mechanism, they only need to remove the liquid outlet from the liquid outlet pipe and then pull out the elastic pressure-boosting component located on the liquid outlet. No complicated tools or cumbersome operations are required, which improves the convenience of cleaning. This invention effectively solves the problem that the existing pressure-boosting mechanism in a Moka pot has a complex structure, making disassembly and installation extremely inconvenient when the user needs to clean it, which seriously affects the user experience.

[0033] Furthermore, the outlet 222 of the elastic pressure booster 22 can elastically deform with pressure changes. When the pressure increases, the outlet 222 expands to allow liquid to pass through. When the pressure decreases, the outlet 222 contracts and closes automatically. The elastic pressure booster 22 can automatically adjust the liquid flow rate according to pressure changes to ensure stable pressure during coffee extraction and improve coffee quality.

[0034] Furthermore, the pressurizing mechanism 2 achieves structural simplicity through the sealed connection between the liquid outlet component 21 and the liquid outlet pipe 1, and the interference fit between the elastic pressurizing component 22 and the liquid outlet component 21. This helps to reduce the number of parts, reduce assembly complexity, and maintain efficient pressurizing function.

[0035] Optionally, in some embodiments, the liquid outlet pipe 1 and the liquid outlet component 21 are threaded together, with the inner side wall of the liquid outlet pipe 1 having an internal thread and the outer side wall of the liquid outlet component 21 having an external thread, so that the liquid outlet pipe 1 and the liquid outlet component 21 can be detachably connected.

[0036] Optionally, in some embodiments, the liquid outlet tube 1 and the liquid outlet component 21 are interference-fitted, and the liquid outlet component 21 is also made of elastic material, so that the user can install or remove the liquid outlet component 21 by simply plugging and unplugging.

[0037] Optionally, in some embodiments, the elastic booster 22 is made of thermoplastic elastomer (TPE) material, which has the characteristics of high elasticity, wear resistance, and easy processing and molding, as well as good chemical resistance and temperature resistance.

[0038] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, the elastic pressure booster 22 is made of silicone material.

[0039] Optionally, in some embodiments, the cross-section of the liquid outlet 222 is in the shape of an "I" and the liquid outlet 222 is a straight slit, which has a simple structure and is easy to process.

[0040] Optionally, in some embodiments, the cross-section of the liquid outlet 222 is cross-shaped, and the liquid outlet 222 is composed of two vertically intersecting slits to form four fan-shaped openings. When the pressure increases, the four fan-shaped areas expand simultaneously, and the liquid flow is more uniform.

[0041] Optionally, in some embodiments, the cross-section of the outlet 222 is "X" shaped, and the outlet 222 is composed of two obliquely intersecting slits to form four triangular openings. The oblique design can reduce the resistance to liquid flow, and the outlet 222 expands more significantly when the pressure increases.

[0042] Furthermore, the cross-section of the inlet 221 is larger than that of the outlet 222. When liquid flows from the inlet 221 with a larger cross-section into the outlet 222 with a smaller cross-section, the flow rate of the liquid will increase. In the Moka pot, as liquid continuously flows in from the inlet 221, the flow of liquid is somewhat hindered due to the smaller cross-section of the outlet 222. This results in pressure buildup inside the elastic pressure booster 22, which helps to better extract the flavor substances and oils in the coffee powder, making the brewed coffee more rich and mellow.

[0043] like Figures 1 to 11The liquid outlet piece 21 shown includes a mounting portion 212 located on the side close to the elastic boosting piece 22, the elastic boosting piece 22 includes a deformation portion 223 in interference fit with the mounting portion 212, and a limiting portion 224 connected with the deformation portion 223, the limiting portion 224 is used to limit the elastic boosting piece 22 from being completely retracted into the mounting portion 212;

[0044] Further, the deformation portion 223 and the mounting portion 212 are in interference fit, so that the elastic boosting piece 22 is tightly connected with the liquid outlet piece 21, the friction generated by the interference fit can effectively prevent the elastic boosting piece 22 from loosening or shifting under the action of liquid pressure, and ensure the stability of the boosting mechanism 2 during operation.

[0045] Further, the limiting portion 224 is provided to limit the elastic boosting piece 22 from being completely retracted into the mounting portion 212, when the elastic boosting piece 22 is deformed due to the increase of liquid pressure, the limiting portion 224 can play a blocking role, avoiding the elastic boosting piece 22 from being damaged due to excessive retraction into the mounting portion 212, or causing the connection structure to fail due to excessive retraction, thereby ensuring that the elastic boosting piece 22 and the liquid outlet piece 21 always maintain an effective connection state.

[0046] Further, the interference fit is provided to make the assembly of the elastic boosting piece 22 and the liquid outlet piece 21 simpler, without the need for additional fasteners, and at the same time, the presence of the limiting portion 224 also makes the disassembly process safer, avoiding damage to the elastic boosting piece 22 due to excessive stretching during disassembly.

[0047] As shown in the drawings, Figures 1 to 11 The deformation portion 223 and the limiting portion 224 are integrally formed and in the shape of a circular truncated cone;

[0048] Further, the integrally formed setting eliminates the connection interface between the deformation portion 223 and the limiting portion 224, avoiding problems such as cracking and loosening that may occur due to insecure connection, and the circular truncated cone structure enables stress to be more evenly distributed on the entire elastic boosting piece 22, compared to other complex or irregular shapes, the circular truncated cone can better disperse stress when bearing pressure, reducing the risk of damage caused by local stress concentration, thereby improving the overall strength and durability of the elastic boosting piece 22.

[0049] Further, the circular truncated cone structure enables the deformation portion 223 to better fit the inner wall of the mounting portion 212 when subjected to pressure, thereby forming a tight seal, which helps to prevent fluid leakage and ensures the normal operation of the boosting mechanism 2.

[0050] Further, the integrally formed setting simplifies the manufacturing process and reduces processing procedures and costs.

[0051] As shown in the drawings, Figures 1 to 11The liquid inlet 221 is located on the side of the limiting portion 224 away from the deformed portion 223, and the lower end surface of the limiting portion 224 is arranged to extend obliquely from the outer side wall of the limiting portion 224 to the liquid inlet 221;

[0052] Further, the oblique arrangement of the lower end surface of the limiting portion 224 is like a flow guide groove, which can guide the liquid to flow more smoothly to the liquid inlet 221. When the liquid enters the space around the elastic pressure booster 22, the inclined surface can naturally concentrate the liquid towards the liquid inlet 221, reducing the dispersion and turbulence of the liquid around, and improving the efficiency of the liquid entering the liquid inlet 221.

[0053] Further, when the liquid flows along the inclined surface to the liquid inlet 221, the flow path of the liquid will change due to the constraint of the inclined surface, thereby forming a certain pressure accumulation near the liquid inlet 221. This pressure accumulation helps to increase the initial pressure of the liquid entering the inside of the elastic pressure booster 22, thereby enhancing the pressure boosting effect of the entire elastic pressure booster 22.

[0054] As shown in the drawings, Figures 1 to 11 The liquid outlet 21 includes a first liquid outlet valve 201 and a second liquid outlet valve 202 detachably connected with the first liquid outlet valve 201. The first liquid outlet valve 201 is provided with a pressure boosting port 203 communicating with the liquid outlet 222 on the side close to the second liquid outlet valve 202. The first liquid outlet valve 201 communicates with the second liquid outlet valve 202 through the pressure boosting port 203. The pressure boosting port 203 is provided with a pressure relief ball 204 which is movably connected with the pressure boosting port 203. When the internal pressure increases, the pressure relief ball 204 moves away from the pressure boosting port 203 to make the first liquid outlet valve 201 and the second liquid outlet valve 202 communicate. When the internal pressure decreases, the pressure relief ball 204 moves close to the pressure boosting port 203 to block the pressure boosting port 203.

[0055] Specifically, under normal circumstances, the pressure relief ball 204 and the pressure boosting port 203 are closed and connected. During the continuous heating process, the internal pressure of the moka pot gradually increases. Under the action of the increasing pressure, the pressure lifts the pressure relief ball 204, so that the pressure relief ball 204 moves away from the pressure boosting port 203, and a gap is formed between the pressure relief ball 204 and the pressure boosting port 203. At this time, the liquid can enter the second liquid outlet valve 202 from the first liquid outlet valve 201 through the pressure boosting port 203. When the internal pressure decreases and under the action of gravity, the pressure relief ball 204 moves close to the pressure boosting port 203 to complete the reset, and the pressure relief ball 204 blocks the pressure boosting port 203, which is conducive to improving the pressure boosting effect of the moka pot, so that the taste of the coffee liquid is more delicate.

[0056] Optionally, the first liquid outlet valve 201 and the second liquid outlet valve 202 can be connected in a threaded connection manner.

[0057] Optionally, the first discharge valve 201 and the second discharge valve 202 can be connected by an interference fit.

[0058] Furthermore, the first outlet valve 201 has a support surface on the side near the second outlet valve 202 that connects to the pressure boosting port 203 and supports the pressure relief ball 204. The support surface is arc-shaped, which allows for better contact with the pressure relief ball 204. Since the pressure relief ball 204 is circular, the arc-shaped support surface can contact the pressure relief ball 204 over a larger contact area. Compared to a flat support, this reduces the sealing gap, thus providing a more reliable sealing effect when the pressure relief ball 204 blocks the pressure boosting port 203. This prevents the liquid or steam inside the moka pot from leaking when not needed, helps maintain the pressure inside the pot, and ensures the pressure boosting effect.

[0059] Furthermore, a sealing element is provided at the connection between the first liquid outlet valve 201 and the second liquid outlet valve 202. The sealing element is an elastic sealing ring. The elastic sealing ring has good elasticity and plasticity, and can fit tightly against the connection between the first liquid outlet valve 201 and the second liquid outlet valve 202 to form an effective sealing barrier.

[0060] like Figures 1 to 11 The liquid outlet component 21 shown is provided with a liquid outlet hole 213 on its outer side wall. The liquid outlet channel 211 includes a first liquid outlet channel 2111 coaxially arranged with the liquid outlet 222, and a second liquid outlet channel 2112 communicating with the first liquid outlet channel 2111 and the liquid outlet hole 213 respectively. The second liquid outlet channel 2112 extends obliquely from the connection between the first liquid outlet channel 2111 and the second liquid outlet channel 2112 toward the liquid outlet hole 213.

[0061] Furthermore, the first liquid outlet channel 2111 and the liquid outlet 222 are coaxially arranged, which can ensure that the liquid flows in the same direction when entering the liquid outlet channel 211, reducing the turbulence and resistance of the liquid in the liquid outlet channel 211. At the same time, the inclined arrangement of the second liquid outlet channel 2112 can guide the liquid to flow more smoothly to the liquid outlet hole 213, further optimizing the liquid flow path and improving the liquid outlet efficiency.

[0062] Furthermore, the inclined second outlet channel 2112 helps stabilize the flow rate and pressure of the liquid. When the liquid flows from the first outlet channel 2111 into the second outlet channel 2112, the inclined structure can make the change in flow rate smoother and reduce the pressure fluctuation caused by sudden changes in flow rate.

[0063] Furthermore, there can be multiple second liquid outlet channels 2112, each second liquid outlet channel 2112 is provided with a corresponding liquid outlet hole 213, and multiple second liquid outlet channels 2112 are simultaneously connected to a first liquid outlet channel 2111.

[0064] As Figures 1 to 11 The elastic booster 22 is made of silica gel material as shown in the figure;

[0065] Further, silica gel has excellent elasticity and can deform to a large extent when subjected to pressure and quickly recover its original shape after the pressure disappears. When liquid enters the inside of the elastic booster 22, the liquid outlet 222 made of silica gel material can expand and contract flexibly according to the pressure, thereby effectively adjusting the outflow amount and speed of the liquid.

[0066] Further, under frequent pressure changes, silica gel material can withstand multiple compression and rebound without fatigue damage. The elastic booster 22 needs to constantly respond to changes in liquid pressure in the booster mechanism 2 and repeatedly deform. The fatigue resistance of silica gel ensures that the elastic booster 22 can maintain stable performance during long-term use and is less likely to have problems such as decreased elasticity or rupture, thereby prolonging the service life of the elastic booster 22.

[0067] Further, silica gel can form a good sealing effect when it comes into contact with other components. The deformed part 223 of the elastic booster 22 is interference-fitted with the mounting part 212 of the liquid outlet 21, and the softness and adhesion of the silica gel material can fill the small gap between the two, preventing liquid leakage.

[0068] As Figures 1 to 11 A moka pot includes an upper pot body 4 and a lower shell 6 detachably connected to the upper pot body 4. The upper pot body 4 includes a liquid outlet pipe 1 and a booster mechanism as described above. One side of the liquid outlet pipe 1 is provided with a mounting groove 41 for mounting the booster mechanism 2 and communicating with the liquid inlet 221. An elastic sealing ring 5 is arranged between the booster mechanism 2 and the mounting groove 41.

[0069] Further, the booster mechanism 2 and the mounting groove 41 are sealed by the elastic sealing ring 5, and the elastic booster 22 inside the booster mechanism 2 also has a certain sealing function. This effectively prevents liquid from leaking under high pressure and ensures good sealing of the moka pot during extraction.

[0070] Further, the booster mechanism 2 is connected to the upper pot body 4 through the mounting groove 41, so that the user can easily disassemble the booster mechanism 2 for cleaning or replacement without the need for complex tools or operations.

[0071] Further, the moka pot comprises a lower shell 6 connected with the upper shell 4, the lower shell 6 is internally provided with a containing cavity 61, the containing cavity 61 is internally provided with a lower shell 62 for containing water, and a heating assembly 63 located below the lower shell 62, by arranging the heating assembly 63 to heat the water in the lower shell 62, without additionally configuring a heating base, the structure is simple, convenient to use, when the user needs to carry the moka pot, without additionally carrying the heating base.

[0072] Optionally, in some embodiments, the upper shell 4 and the lower shell 6 can adopt a snap connection connection mode, the inner side wall of the upper shell 4 is spaced apart in the circumferential direction and is provided with a connection buckle, the outer side wall of the lower shell 6 is provided with a connection buckle groove corresponding to the connection buckle, the connection buckle and the connection buckle groove are buckled to enable the upper shell 4 and the lower shell 6 to be detachably connected, through the buckling of the connection buckle and the connection buckle groove, the upper shell 4 and the lower shell 6 can be firmly connected together, reducing the risk of connection falling off due to vibration, impact and the like, thereby improving the reliability of the connection, in addition, when the user needs to disassemble the upper shell 4 and the lower shell 6, the user only needs to simply release the buckling, and the two can be easily separated without using additional tools or equipment, which is conducive to improving the convenience of disassembly.

[0073] Optionally, the cross section of the connection buckle is "L" type, and the cross section of the connection buckle groove is "L" type buckle groove matched with the connection buckle, the L-shaped arrangement can provide a larger contact area, which is conducive to improving the stability of the connection, and the disassembly is convenient.

[0074] Optionally, the cross section of the connection buckle is "T" type, and the cross section of the connection buckle groove is "T" type buckle groove matched with the connection buckle, the T-shaped arrangement can prevent the displacement of the upper shell 4 and the lower shell 6 in the horizontal direction.

[0075] Optionally, the cross section of the connection buckle is trapezoidal, and the cross section of the connection buckle groove is a trapezoidal groove matched with the connection buckle, the trapezoidal arrangement can prevent the separation of the upper shell 4 and the lower shell 6 in the vertical direction.

[0076] Optionally, the cross section of the connection buckle is hook-shaped, and the cross section of the connection buckle groove is a hook-shaped groove matched with the connection buckle, the hook-shaped arrangement can provide strong locking force to prevent the separation of the upper shell 4 and the lower shell 6.

[0077] Optionally, in some embodiments, the upper body 4 and the lower shell 6 can be connected by a threaded connection. The threaded connection increases the connection area and connection strength by increasing the number and depth of threads, thereby providing higher connection strength and stability. Under the pressure inside the moka pot, the self-locking characteristic between the threads can prevent the upper body 4 and the lower shell 6 from accidentally separating during use. Secondly, the threaded connection can make the threads between the upper body 4 and the lower shell 6 fit tightly by rotating the upper body 4 and the lower shell 6, which can provide uniform pressure on the entire circumference, thereby forming a good sealing effect.

[0078] Optionally, the heating component 63 is an electric heater.

[0079] like Figures 1 to 11 The mounting groove 41 shown includes a first mounting groove 411 for mounting the ends of the elastic booster 22 and the liquid outlet 21, and a second mounting groove 412 connected to the first mounting groove 411 and for accommodating the elastic sealing ring 5;

[0080] Furthermore, the first mounting groove 411 provides a precise mounting position for the ends of the elastic pressure booster 22 and the liquid outlet 21, ensuring the stability and reliability of the elastic pressure booster 22 and the liquid outlet 21 in the moka pot. The second mounting groove 412 is used to accommodate the elastic sealing ring 5, which helps to enhance the sealing between the various parts of the moka pot, prevents the coffee liquid from leaking during the extraction process, and ensures the taste and quality of the coffee.

[0081] Furthermore, the mounting groove 41 is designed to allow for easy assembly and disassembly of components such as the elastic pressurizing element 22, the liquid outlet element 21, and the elastic sealing ring 5, which is beneficial for the daily maintenance and cleaning of the moka pot.

[0082] Optionally, in some embodiments, the end of the liquid outlet 21 is threadedly connected to the first mounting groove 411.

[0083] Optionally, in some embodiments, the end of the liquid outlet 21 is inserted into the first mounting groove 411.

[0084] like Figures 1 to 11 The side of the liquid outlet pipe 1 away from the pressurizing mechanism 2 is inclinedly connected to the upper vessel body 4 to form a rounded corner;

[0085] Furthermore, during the use of the moka pot, the connection between the dispensing tube 1 and the upper pot body 4 will be subjected to certain pressure and stress. The rounded corners can evenly distribute these stresses to the surrounding materials, avoiding stress concentration at a certain point or in a certain area. Compared with right-angle connections, rounded corners can reduce the risk of cracks or damage caused by stress concentration, enhance the structural strength and durability of the connection, and effectively extend the service life of the moka pot.

[0086] Furthermore, the inclined connection and rounded corners make the connection between the liquid outlet tube 1 and the upper body 4 smoother and more natural, which helps to improve the overall aesthetics of the moka pot.

[0087] Furthermore, the liquid outlet pipe 1 and the upper vessel body 4 are integrally formed.

[0088] The implementation method of Example 1 is as follows:

[0089] A pressurizing mechanism includes a pressurizing mechanism 2 sealed to an outlet pipe 1. The pressurizing mechanism 2 includes an outlet component 21 threaded to the outlet pipe 1 and an elastic pressurizing component 22 interference-fitted with the outlet component 21. The outlet component 21 has an outlet channel 211, and the elastic pressurizing component 22 has an inlet 221 and an outlet 222 capable of elastic deformation. The inlet 221 communicates with the outlet channel 211 through the outlet 222. When the internal pressure increases, the outlet 222 on the elastic pressurizing component 22 springs back. The elastic deformation is in an expanding state. When the internal pressure decreases, the outlet 222 returns to its elastic deformation and contracts. When the user needs to clean the pressurizing mechanism, he / she only needs to remove the outlet part 21 from the outlet pipe 1 and then pull out the elastic pressurizing part 22 located on the outlet part 21. No complicated tools or cumbersome operations are required, which improves the convenience of cleaning and effectively solves the problem that the existing pressurizing mechanism in the Moka pot has a complicated structure, and when the user needs to clean it, the disassembly and installation are extremely inconvenient, which seriously affects the user's experience.

[0090] The elastic pressure booster 22 is made of silicone material.
