Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a moka pot with an adjustable powder chamber. Background Technology

[0002] A moka pot is a traditional Italian espresso-making tool, typically consisting of an upper and lower pot. Between the upper and lower pots is a coffee grounds chamber containing a coffee filter. The lower pot holds water, which, when heated, generates a large amount of steam. The steam forces the hot water upwards into the coffee grounds chamber, extracting the coffee essence before flowing upwards and collecting in the upper pot. For example, the moka pot disclosed in Chinese invention patent application number 202211129708.8.

[0003] Most Moka pots on the market have a fixed coffee cup capacity based on their size, making it difficult for users to flexibly choose the amount of coffee they want to make. For example, if a user uses a Moka pot with a maximum capacity of six cups to make three cups of coffee, the coffee grounds won't fill the filter completely, leaving a lot of empty space at the top. After extraction, this excess space will contain a lot of leftover coffee. Conversely, using six cups' worth of coffee grounds to make three cups avoids this problem, but it results in significant coffee grounds waste. Utility Model Content

[0004] The technical problem to be solved by this invention is to propose a moka pot with an adjustable powder chamber that can freely change its volume, in response to the above-mentioned technical situation.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a moka pot with an adjustable powder cavity, comprising an upper pot body and a lower pot body that are detachably connected, characterized in that the lower part of the upper pot body is open, and a flow plate is provided at the opening; the lower pot body is provided with an adjustable platform that can move vertically along its inner wall; the top surface of the flow plate and the adjustable platform and the inner wall of the lower pot body together form an adjustable powder cavity for accommodating coffee powder.

[0006] To enable the adjustable platform to move smoothly vertically and be fixed at any height, preferably, the adjustable platform is threadedly connected to the lower pot body, and the adjustable platform rotates and rises and falls relative to the lower pot body via the thread.

[0007] To provide a simple structure for inputting hot water into the powder chamber, preferably, the adjustable platform is provided with a hot water pipe extending vertically, and the outlet of the hot water pipe is located on the top surface of the adjustable platform.

[0008] Preferably, a guide pipe is fixedly installed inside the lower kettle body, and the guide pipe is sleeved outside the hot water pipe. The guide pipe can guide the vertical sliding of the hot water pipe, and the lower end of the guide pipe remains at a constant height, so that hot water always flows into the hot water pipe through the guide pipe.

[0009] Furthermore, the outer wall of the adjustable platform and the inner wall of the lower kettle body are sealed together, and the inner wall of the guide pipe and the outer wall of the hot water pipe are sealed together.

[0010] Preferably, the adjustable platform is equipped with a water inlet filter at its top; the top surface of the adjustable platform is provided with supporting ribs, and the water inlet filter is supported by the supporting ribs, forming a flow gap between the water inlet filter and the top surface of the adjustable platform. Coffee powder is placed above the water inlet filter to prevent coffee powder from entering the hot water pipe, and the flow gap formed between the water inlet filter and the top surface of the adjustable platform facilitates the uniform horizontal diffusion of hot water after it flows out of the hot water pipe.

[0011] To facilitate user control of the adjustable platform, a handle is preferably provided on the top of the adjustable platform.

[0012] To avoid the height of the powder chamber being limited by the height of the handle, it is preferable that the handle is rotatably mounted on the top of the adjustable platform, and that the handle can be abutted against the top of the adjustable platform or pulled up.

[0013] To facilitate gripping the handle, preferably, the handle is arc-shaped, with its middle section recessed inward to form a gripping part that facilitates applying force to lift the handle upright.

[0014] Preferably, the moka pot also includes a base, with the lower pot body mounted on the base. A water supply pipe is installed within the base, and both ends of the water supply pipe are connected to a hot water pipe in the lower pot body and an external water tank, respectively. A water pump is installed between the water tank and the water supply pipe. This solution improves upon the traditional steam pressure water delivery method by replacing it with a water pump, avoiding safety risks to the moka pot caused by excessive steam pressure.

[0015] Compared with existing technologies, the advantage of this invention lies in abandoning the traditional filter cup structure with a fixed volume. Instead, it uses a flow plate, an adjustable platform top surface, and the inner wall of the lower pot to create an adjustable coffee chamber. As the adjustable platform moves vertically along the inner wall of the lower pot, the volume of the coffee chamber can be dynamically adjusted, allowing users to flexibly control the size of the chamber according to the desired coffee volume. This design effectively avoids the problem of residual water accumulation caused by an excessively large coffee chamber volume and insufficient coffee powder filling, thereby reducing dilution of the extract and ensuring the stability of the coffee's flavor.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-6 The image shows a preferred embodiment of the adjustable powder chamber moka pot of this utility model.

[0024] The moka pot in this embodiment includes an upper pot body 1, a lower pot body 2, and a base 12, as follows: Figure 1 As shown, the lower part of the upper pot 1 has internal threads, and the upper part of the lower pot 2 has matching external threads. The upper pot 1 and the lower pot 2 are detachably threaded, allowing the user to add coffee powder to the moka pot by separating the upper pot 1 and the lower pot 2. The lower pot 2 is mounted on the base 12, which contains a water supply pipe. The two ends of the water supply pipe are connected to the lower pot 2 and an external water tank, respectively. A water pump is installed between the water tank and the water supply pipe.

[0025] The upper pot 1 is used to collect the extracted coffee liquid. The bottom of the upper pot 1 has an opening, and a flow plate 3 is provided at the opening to prevent coffee powder from passing through. The interior of the lower pot 2 has an adjustable platform 4 that can move vertically along its inner wall. The top surface of the adjustable platform 4, together with the flow plate 3 at the bottom of the upper pot 1 and the inner wall of the lower pot 2, forms an adjustable powder cavity 5 for containing coffee powder.

[0026] As the adjustable platform 4 moves vertically along the inner wall of the lower pot 2, the volume of the coffee grounds chamber 5 can be dynamically adjusted, allowing users to flexibly control the size of the chamber 5 according to the desired coffee volume. This design effectively avoids the problem of residual water accumulation caused by an excessively large chamber 5 or insufficient coffee grounds, thereby reducing dilution of the extract and ensuring the stability of the coffee's flavor. Figure 2 As shown, the Moka pot's powder chamber 5 is in its large-capacity state, suitable for making multiple cups of coffee. When users need to make a smaller amount of coffee, such as... Figure 3 As shown, adjust the coffee grounds chamber 5 of the Moka pot to a small volume state so that a smaller amount of coffee grounds can just fill the coffee grounds chamber 5.

[0027] like Figure 6 As shown, the adjustable platform 4 has a vertically extending hot water pipe 6. The outlet of the hot water pipe 6 is located on the top surface of the adjustable platform 4, and a one-way valve is installed at the inlet of the hot water pipe 6. A guide pipe 7 is also fixedly installed inside the lower kettle body 2, and the guide pipe 7 is fitted over the hot water pipe 6. The guide pipe 7 guides the vertical sliding of the hot water pipe 6. The lower end of the guide pipe 7 remains at a constant height and is connected to the water supply pipe inside the base 12, ensuring that hot water always flows into the hot water pipe 6 through the guide pipe 7. A sealing ring 8 is provided between the inner wall of the guide pipe 7 and the outer wall of the hot water pipe 6 to ensure a tight seal. Similarly, a sealing ring 8 is also provided between the outer wall of the adjustable platform 4 and the inner wall of the lower kettle body 2 to ensure a tight seal.

[0028] The top of the adjustable platform 4 is equipped with, for example, Figure 2 and Figure 4 The coffee powder is contained within the inlet filter 9 and the flow plate 3 located at the bottom of the upper kettle body 1. The top surface of the adjustable platform 4 has a supporting ridge 10, which supports the inlet filter 9, creating a flow gap between it and the top surface of the adjustable platform 4. The coffee powder is positioned above the inlet filter 9 to prevent it from entering the hot water pipe 6. Simultaneously, the flow gap between the inlet filter 9 and the top surface of the adjustable platform 4 facilitates the even horizontal diffusion of hot water as it flows out of the hot water pipe 6.

[0029] like Figure 2 As shown, the adjustable platform 4 is threadedly connected to the lower pot body 2, allowing the adjustable platform 4 to move smoothly vertically and be fixed at any height. To facilitate user control of the adjustable platform 4, a handle 11 is provided on the top of the adjustable platform 4, which controls the raising and lowering of the adjustable platform 4 by turning clockwise or counterclockwise. To avoid the height of the powder chamber 5 being limited by the height of the handle 11, in this embodiment, the handle 11 is rotatably mounted on the top surface of the adjustable platform 4, resting against the top of the adjustable platform 4 in its natural state, and only standing upright under force during use. The handle 11 is made of elastic material, and when standing upright under force, it always has a tendency to return to the state of resting against the top of the adjustable platform 4. The handle 11 is arc-shaped, as... Figure 5 As shown, the middle section is concave towards the inner side of the arc to form a gripper part that facilitates the application of force to make the handle 11 stand up.
