Description

Technical Field

[0001] This utility model relates to the field of coffee component extraction technology, and in particular to a pressurized coffee component extraction device. Background Technology

[0002] Coffee is a very popular beverage. It comes from coffee beans, and the process of making coffee includes picking, processing (such as fermentation and drying), roasting and grinding, and finally brewing it with hot water to make the coffee beverage we usually drink.

[0003] For example, patent application number 202221801597.6 published on the China Patent Network, entitled "A Pressurized Coffee Component Extraction Device," includes: a housing and a water tank. The water tank is installed in the middle of the top of the housing. A brewing trough is provided on the front surface of the housing near the bottom. A connecting pipe is installed at the top of the brewing trough, and a brewing head is installed at the bottom of the connecting pipe. A heating chamber is installed at the bottom of the housing. A pressurizing tank is installed near the bottom of the housing. A pressure reducer is installed on one side of the top of the housing. A pressure reducing chamber A is installed on one side of the pressure reducer, and a pressure reducing chamber B is installed on the side of the pressure reducer near pressure reducing chamber A. This pressurized coffee component extraction device solves the problem of existing devices where the extraction pressure directly acts on the brewing head, making it impossible to slowly increase the brewing pressure and slowly extract coffee powder, resulting in poor coffee extraction. It improves the extraction effect of coffee powder, thereby improving the brewing effect of coffee powder.

[0004] However, existing coffee component extraction devices mainly rely on increasing liquid pressure for pressurized extraction. As coffee powder is washed by water, its thickness decreases. When the continuously pressurized liquid washes over the coffee powder with its reduced concentration, the concentration of the extract will decrease. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the concentration of coffee powder decreases during the continuous rinsing process of the existing direct pressurization liquid method, and to propose a pressurized coffee component extraction device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pressurized coffee component extraction device, including a coffee machine;

[0008] A booster water inlet connected to the output of the coffee machine;

[0009] The coffee machine has a filter pot on its front side, which is fitted onto the surface of the pressure inlet. The filter pot contains coffee powder, and a support is provided at the bottom of the filter pot. The surface of the coffee machine has a transmission structure that can use the support to lift the filter pot and change the distance between it and the pressure inlet.

[0010] As a preferred technical solution of this application, the transmission structure includes a connecting frame fixedly connected to the right side of the coffee machine, a screw movably connected inside the connecting frame via a bearing, a bracket sleeved on the surface of the screw and threadedly connected to the screw, and the top end of the screw extending through to the top of the connecting frame and fixedly connected to a wheel.

[0011] As a preferred technical solution of this application, the support is movably connected to a sleeve, which is sleeved on the surface of the filter and movably connected to the filter, and the sleeve can drive the filter to rotate.

[0012] As a preferred technical solution of this application, a toothed ring is fixedly connected to the bottom of the sleeve, and a toothed column located on the left side of the connecting frame is movably connected to the top of the coffee machine through a bearing. The toothed column and the toothed ring mesh with each other. A gear is fixedly connected to the surface of the screw, and the gear is located on the right side of the toothed column and meshes with the toothed column.

[0013] As a preferred technical solution of this application, a movable block is fixedly connected to the surface of the connecting frame, and a shaft is movably connected inside the movable block through a bearing. Both ends of the shaft are fixedly connected to pressure plates. The side of the pressure plate away from the shaft extends to the top of the filter and is fixedly connected to a spring plate. The side of the spring plate away from the pressure plate contacts the top of the filter and the spring plate is elastic.

[0014] As a preferred technical solution of this application, both sides of the shaft surface are threaded with threaded sleeves, the inner side of the threaded sleeves is in contact with the surface of the movable block, and the threaded sleeves can fix the shaft by means of thread compression.

[0015] Compared with the prior art, this utility model provides a pressurized coffee component extraction device, which has the following beneficial effects:

[0016] 1. This pressurized coffee component extraction device directly adjusts the impact force of high-pressure water flow on coffee powder by changing the distance between the filter pot and the pressurized water inlet. A smaller distance can increase the water pressure and improve extraction efficiency; a larger distance can reduce the pressure and avoid over-extraction, thus solving the problem of gradual concentration reduction caused by traditional fixed pressurization.

[0017] 2. This pressurized coffee component extraction device has a self-locking screw drive, which can precisely control the slight displacement of the filter pot's lifting and lowering, avoid sudden changes in water pressure, and ensure stable extraction parameters.

[0018] 3. This pressurized coffee component extraction device avoids the formation of fixed water flow channels by rotating the filter pot, which reduces extraction dead zones caused by uneven local powder density, improves the consistency of coffee liquid concentration, and prevents coffee powder from clumping on the filter screen surface, maintaining stable water flow permeability.

[0019] 4. This pressurized coffee component extraction device automatically synchronizes lifting and rotating movements via gears and rings, eliminating the need for additional user operation and simplifying the process. The gear transmission ratio can be designed so that each unit of height of the filter pot corresponds to a specific rotation angle, ensuring that the coffee powder is fully washed and covered.

[0020] 5. This pressurized coffee component extraction device adapts to the position changes of the filter pot during the lifting and lowering process through the elastic pressure of the spring plate, always maintaining the top pressure and ensuring the friction between the filter pot and the sleeve.

[0021] 6. This pressurized coffee component extraction device allows for fine adjustment of the pressure of the spring plate on the filter pot via a screw sleeve, adapting to the sealing requirements of filter pots made of different materials. The screw sleeve thread design allows for quick locking or releasing of the shaft, facilitating the installation and disassembly of the filter pot. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0028] Reference Figure 1-4 A pressurized coffee component extraction device, comprising a coffee machine 1;

[0029] The booster water inlet 2 is connected to the output end of coffee machine 1;

[0030] A coffee machine 1 has a filter pot 3 on its front, which is fitted onto the surface of the pressurized water inlet 2. The filter pot 3 contains coffee powder. A support 4 is located at the bottom of the filter pot 3. A transmission structure 5 is located on the surface of the coffee machine 1. This transmission structure 5 uses the support 4 to lift the filter pot 3 and change the distance between it and the pressurized water inlet 2. By changing the distance between the filter pot 3 and the pressurized water inlet 2, the impact force of the high-pressure water flow on the coffee powder is directly adjusted. A smaller distance increases the water pressure and improves extraction efficiency; a larger distance reduces the pressure and avoids over-extraction, thus solving the problem of gradually decreasing concentration caused by traditional fixed pressurization. The transmission structure 5 includes a connecting frame 6 fixedly connected to the right side of the coffee machine 1. A screw 7 is movably connected to the inside of the connecting frame 6 via a bearing. The support 4 is fitted onto the surface of the screw 7 and threadedly connected to it. The top of the screw 7 extends through to the top of the connecting frame 6 and is fixedly connected to a wheel 8. A sleeve 9 is movably connected to the inside of the support 4 and fits onto the filter pot 3. The surface of the kettle 3 is movably connected to the filter kettle 3. The sleeve 9 can drive the filter kettle 3 to rotate. The bottom of the sleeve 9 is fixedly connected to the toothed ring 10. The top of the coffee machine 1 is movably connected to the toothed column 11 located on the left side of the connecting frame 6 through the bearing. The toothed column 11 and the toothed ring 10 mesh with each other. The surface of the screw 7 is fixedly connected to the gear 12. The gear 12 is located on the right side of the toothed column 11 and meshes with the toothed column 11. The surface of the connecting frame 6 is fixedly connected to the movable block 13. The inside of the movable block 13 is movably connected to the shaft 14 through the bearing. Both ends of the shaft 14 are fixedly connected to the pressure plate 15. The side of the pressure plate 15 away from the shaft 14 extends to the top of the filter kettle 3 and is fixedly connected to the spring plate 16. The side of the spring plate 16 away from the pressure plate 15 contacts the top of the filter kettle 3. The spring plate 16 is elastic. Both sides of the surface of the shaft 14 are threadedly connected to the threaded sleeve 17. The inner side of the threaded sleeve 17 contacts the surface of the movable block 13. The threaded sleeve 17 can fix the shaft 14 by the threaded compression.

[0031] Specifically, during operation / use of this pressurized coffee component extraction device: the user loads coffee powder into the filter pot 3 and installs it onto the bracket 4 on the front of the coffee machine 1, connecting the bottom bracket 4 to the transmission structure 5. The filter pot 3 is fitted onto the surface of the pressurized inlet 2, maintaining an initial distance between the filter pot 3 and the pressurized inlet 2. The spring plate 16 naturally contacts the top of the filter pot 3 through the pressure plate 15, ensuring a seal. As the filter pot 3 is continuously flushed by the pressurized inlet 2, the user rotates the wheel 8, driving the screw 7 to rotate within the connecting frame 6. Because the bracket 4 and the screw 7 are threadedly connected, the rotation of the screw 7... The movable support 4 and the filter pot 3 rise or fall vertically, thereby dynamically adjusting the distance between the filter pot 3 and the pressurized water inlet 2. When the screw 7 rotates, the gear 12 on its surface synchronously drives the gear column 11 to rotate. The gear column 11 meshes with the gear ring 10 at the bottom of the sleeve 9, forcing the sleeve 9 to drive the filter pot 3 to rotate around its axis, ensuring the uniformity of subsequent water flow. After the coffee machine 1 is started, the pressurized water inlet 2 injects high-pressure hot water or steam into the filter pot 3. Since the filter pot 3 is in an upward state and the distance between it and the pressurized water inlet 2 is reduced, the water flow impact force is enhanced. At the same time, the rotation of the filter pot 3 makes the coffee powder evenly rinsed in dynamic tumbling.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
