Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present application. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of the technical solutions appears to be contradictory or unable to be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope of the present application.

[0026] In the embodiments of the present application, please refer to Figures 1-6As shown in the figure, a double-pressure Moka pot with adjustable pressure mainly includes: a pot body, which includes an upper pot 1 and a lower pot 2. The upper pot 1 and the lower pot 2 are connected by threads. An outlet pipe 18 is arranged inside the upper pot 1, and an outlet channel 3 communicating with the bottom of the upper pot 1 is formed inside the outlet pipe 18. A pressure regulating mechanism is arranged inside the outlet channel 3, and a safety valve 4 is arranged inside the lower pot 2. The pressure regulating mechanism includes a fixing part 5, a pressure-bearing ring 6, a spring 7 and an adjusting rod 8. Among them, the fixing part 5 is fixed at the bottom of the outlet channel 3, a circular opening is left in the middle of the fixing part 5, the pressure-bearing ring 6 is movably arranged on the fixing part 5, the spring 7 is installed inside the pressure-bearing ring 6, the adjusting rod 8 is threadedly connected inside the outlet channel 3, the bottom of the adjusting rod 8 is slidably connected with the pressure-bearing ring 6, and the adjusting rod 8 is rotated to adjust the length of its extension into the pressure-bearing ring 6, so as to adjust the compression amount of the spring 7, thereby adjusting the threshold value of the movement of the pressure-bearing ring 6, and further realizing the adjustability of the pressure in the lower pot 2. When the Moka pot is in the heating state, the lower pot 2 is in a closed state and pressure will be generated inside. Before heating, the pressure is adjusted through the pressure regulating mechanism so that the pressure generated during heating reaches the adjusted pressure value.

[0027] Next, some preferred / improved embodiments based on the above embodiments will be further elaborated. Any one or a combination of multiple of the following embodiments can be selected.

[0028] As Figure 4 shown, a gap is left between the lower section of the adjusting rod 8 and the inner wall of the outlet channel 3 as a channel for liquid circulation.

[0029] Furthermore, a limiting part 9 is formed on the adjusting rod 8, and the maximum sliding depth of the adjusting rod 8 is limited by cooperating with the top of the outlet channel 3, so as to limit the maximum adjustable pressure in the lower pot 2.

[0030] Specifically, it further includes a percolator 13, which is detachably arranged inside the lower pot 2. The bottom of the percolator 13 is funnel-shaped and extends to the bottom of the lower pot 2. The percolator 13 serves as a container for placing coffee powder.

[0031] Furthermore, a lower filter sheet 14 is installed inside the percolator 13, and a detachable upper filter sheet 15 is arranged at the top of the percolator 13. The lower filter sheet 14 can ensure that the liquid in the lower pot 2 flows upward while the coffee powder does not fall downward, and the upper filter sheet 15 is used to block the coffee powder residue from flowing upward into the outlet channel 3.

[0032] As Figure 3 shown, a sealing ring 17 is arranged between the upper filter sheet 15 and the lower pot 2, which ensures the sealing between the upper pot 1 and the lower pot 2 and prevents the liquid from flowing out through the gap between the two.

[0033] As Figure 6As shown, a number of liquid outlet holes 10 are formed in the liquid outlet channel 3. The liquid outlet holes 10 communicate with the liquid outlet channel 3 and the interior of the upper pot 1. The liquid outlet holes 10 communicate downward with the interior of the upper pot 1, preventing the upward splashing of coffee liquid.

[0034] Furthermore, an O-ring 11 is installed on the adjusting rod 8. The O-ring 11 blocks the gap between the adjusting rod 8 and the liquid outlet channel 3, thereby restricting the upward flow of coffee liquid from the gap between the adjusting rod 8 and the liquid outlet pipe 18. The coffee liquid enters the liquid outlet channel 3 from the lower pot 2 and, under the blockage of the O-ring 11, flows into the upper pot 1 through a number of liquid outlet holes 10.

[0035] As Figure 5 shown, the pressure-bearing ring 6 is a stepped cylinder, and the end with a slightly smaller diameter slides within the fixing member 5 to position the pressure-bearing ring 6.

[0036] As Figure 1 shown, an adjusting knob 12 is installed at the top of the adjusting rod 8 to facilitate the operation of rotating the adjusting rod 8.

[0037] Furthermore, a handle 16 is threadedly installed on the upper pot 1 to facilitate the handling of the pot body.

[0038] During the specific use process, after adding water to the lower pot 2 and coffee powder to the percolator 13, the percolator 13 is placed on the lower pot 2, and the upper filter 15 is placed over the coffee powder to complete the preparatory work before use.

[0039] The lower pot 2 is heated. The gasification of the liquid causes the air pressure in the lower pot 2 to rise, which in turn pushes the water in the lower pot 2 upward. After passing through the percolator 13, the coffee powder is extracted into coffee liquid. The coffee liquid continues to flow upward into the liquid outlet channel 3. At this time, the coffee liquid is blocked by the pressure-bearing ring 6 and the adjusting rod 8. When the lower pot 2 reaches a certain pressure, under the action of hydraulic pressure, the spring 7 compresses, pushing the pressure-bearing ring 6 upward. The coffee liquid continues to flow upward through the gap between the fixing member 5 and the pressure-bearing ring 6 and finally flows into the upper pot 1 through the liquid outlet holes 10 on the liquid outlet pipe 18. At the same time, under the blockage of the O-ring 11, the coffee liquid does not overflow from the top of the liquid outlet pipe 18.

[0040] If it is necessary to adjust the maximum pressure in the lower pot 2 during heating, rotate the adjusting rod 8 to control the compression amount of the spring 7, so as to change the threshold value for further compression of the spring 7, and then control the hydraulic pressure of the coffee liquid during liquid outlet, thereby extracting coffee liquid with different tastes.

[0041] So far, various embodiments of the present application have been described in detail. To avoid obscuring the concept of the present application, some details well known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present application. The foregoing embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
