Description

Technical Field

[0001] This utility model relates to the field of moka pot technology, and in particular to a moka pot with adjustable extraction pressure. Background Technology

[0002] A moka pot is a common coffee extraction tool. It heats water in the lower chamber, increases the air pressure in the lower chamber through steam, and then transports the hot water upward through a funnel. The hot water passes through the coffee grounds on the filter screen to extract the coffee liquid, which finally flows into the upper chamber through the outlet channel and outlet hole, thus completing the coffee extraction process.

[0003] Conventional moka pots are typically single-pressure moka pots with only a pressure relief valve in the lower chamber. The lower chamber has relatively low pressure, resulting in a less flavorful extracted coffee. A double-pressure moka pot, as disclosed in Chinese Patent Publication No. CN217488300U, uses pressure valves in both the lower and upper chambers to provide greater pressure, allowing the coffee to flow from the upper chamber and increasing its concentration and flavor. However, the extraction pressure is not adjustable. Existing double-pressure moka pots with adjustable pressure, such as the one disclosed in Chinese Patent Publication No. CN222968352U, allow for pressure adjustment in the lower chamber, but lack an indicator of the specific pressure setting. This means adjustment is based solely on feel, and the user cannot determine the exact pressure in the lower chamber during extraction.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. In addition, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope of the present utility model.

[0020] In this embodiment of the utility model, please refer to Figure 1-4As shown, this adjustable extraction pressure moka pot mainly includes: an upper pot 1 and a lower pot 2 that can be assembled and disassembled. A funnel 3 is installed inside the lower pot 2, and a filter screen 4 is installed inside the funnel 3. A liquid column 5 is formed from bottom to top inside the upper pot 1. An installation hole 6 connecting the upper pot 1 and the lower pot 2 is opened at the center of the liquid column 5. A support ring 7 is formed at the bottom of the installation hole 6, and a movable plug 8 is supported on the support ring 7. A spring 9 is installed above the movable plug 8. A rotating rod 10 is threaded into the installation hole 6, and the bottom of the rotating rod 10 abuts against the top of the spring 9. The liquid column 5 has openings on both sides... The container is provided with a liquid outlet 12 connecting the upper pot 1 and the mounting hole 6. A liquid outlet channel 11 is provided on the inner wall of the liquid outlet column 5, which extends from above the support ring 7 to the liquid outlet 12. An indicator groove 13 is also provided on the liquid outlet column 5, which passes through one side of the liquid outlet column 5. The outer surface of the liquid outlet column 5 on one side of the indicator groove 13 is marked with a scale 14 representing the air pressure. An indicator 15 is coaxially hinged to the rotating rod 10. The indicator 15 includes a pointer 1501 that indicates the scale 14. The indicator 15 can move axially within the indicator groove 13 as the rotating rod 10 rotates.

[0021] Specifically, the spring 9 is installed in the mounting hole 6, located between the rotating rod 10 and the movable plug 8. The adjustable range of the rotating rod 10 is the length range of the indicator groove 13. When the rotating rod 10 moves up and down in the mounting hole 6, its bottom always keeps pressing against the spring 9, and the plug is always subjected to a certain downward pressure.

[0022] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0023] like Figure 1-2 As shown, the unit of the scale 14 is kPa, and the adjustable range is 150-350. The values ​​of the scale 14 increase from top to bottom in increments of 50.

[0024] Furthermore, combined with Figure 4 As shown, for easy observation, the end of the pointer 1501 is bent and closely attached to the outer surface of the liquid column 5, and the bent part of the pointer 1501 is used to indicate the scale 14.

[0025] Furthermore, to facilitate the turning of the rotating rod 10, an operating knob 16 is fixed to the top of the rotating rod 10.

[0026] like Figure 3As shown, a limiting ring groove is formed on the upper part of the rotating rod 10, and a sealing sleeve 17 is provided in the limiting ring groove. The sealing sleeve 17 prevents coffee liquid from overflowing from the gap between the rotating rod 10 and the mounting hole 6. The sealing sleeve 17 is made of rubber and can move synchronously in the mounting hole 6 as the rotating rod 10 moves up and down.

[0027] Furthermore, the bottom of the movable plug 8 is a rubber layer 801. The rubber layer 801 can deform when the movable plug 8 is pressed, pressing the support ring 7 so that the gap between the movable plug 8 and the support ring 7 is different for hot water to pass through, unless the movable plug 8 is lifted away from the support ring 7, in order to maintain the airtightness of the lower kettle 2.

[0028] When in use, first put water into the lower chamber 2, add coffee powder into the filter screen 4, heat the lower chamber 2, the liquid in the lower chamber 2 vaporizes, the air pressure increases until it pushes open the movable stopper 8, the hot water flows through the funnel 3-coffee powder-liquid outlet channel 11-liquid outlet hole 12, and finally flows into the upper chamber 1. By operating the rotating rod 10 to change its length in the mounting hole 6, the compression of the spring 9 is adjusted to regulate the air pressure of the lower chamber 2 during extraction. The user can know the adjusted air pressure of the lower chamber 2 by the scale 14 corresponding to the pointer 1501 on the indicator 15.

[0029] Various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details 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.

The foregoing embodiments are only used to illustrate the technical solutions of the present utility model, and are not intended to limit it. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
