Description

Technical Field

[0001] The present invention relates to the field of coffee machines, and in particular to a liquid extraction structure of a cold extraction coffee machine. Background Art

[0002] The extraction liquid structure of the coffee machine mainly involves the production and collection of liquid during the extraction process, and is the key part of the coffee machine to achieve the coffee extraction function. However, the traditional extraction liquid structure has many problems in use due to its structural design: (1) In a conventional powder cartridge containing coffee raw materials, the filter at the bottom is an integrated structure with the powder cartridge or is fixed inside the powder cartridge. When cleaning the powder cartridge, the coffee grounds inside the powder cartridge need to be manually taken out, but the very fine coffee grounds remaining on the filter are difficult to remove.

[0003] (ii) During the extraction process of the traditional powder cartridge, the user needs to hold the powder cartridge by hand and place it into the liquid storage cartridge. This process not only easily causes food hygiene problems, but also increases the cumbersome operation experience.

[0004] (3) In traditional powder cartridges, the contact between the coffee raw materials and the injected water is by immersion. This immersion contact method causes the water inlet to be blocked by extremely fine powder to a certain extent, resulting in insufficient extraction of the coffee raw materials into liquid, affecting the taste of the liquid, and inevitably blocking the water outlet, causing inconvenience in cleaning. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a liquid extraction structure for a cold brew coffee machine to solve one or more problems in the prior art.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A liquid extraction structure of a cold brew coffee machine includes an operating panel placed on a countertop, the liquid extraction structure includes a liquid storage cylinder, and the liquid storage cylinder is arranged at the upper end of the operating panel along a first direction; the liquid extraction structure also includes a production component, the production component includes a material collection part and a liquid guide part, and the liquid guide part is partially matched with the material collection part.

[0007] Furthermore, the collecting part includes a powder cylinder, and the powder cylinder is provided with a protrusion and a first recessed part at the end surface away from the operation panel; the powder cylinder is matched with the end surface of the liquid storage cylinder away from the operation panel through the protrusion.

[0008] Furthermore, the powder cylinder is concealed in the liquid storage cylinder; the material collecting portion includes a material cover, and the material cover is arranged in the first recessed portion.

[0009] Furthermore, the collecting portion further comprises a filter plate and a diverter plate, wherein the filter plate is detachably arranged at the end of the powder cylinder; a second recessed portion is further arranged on the surface of the first recessed portion, and the diverter plate is detachably arranged at the second recessed portion.

[0010] Furthermore, the liquid guiding portion includes a tube body, and the tube body penetrates the operation panel, the liquid storage cylinder and the material collecting portion along a first direction.

[0011] Furthermore, holes are evenly arranged on the surface of the tube body, and the holes are located between the diverter plate and the material cover.

[0012] Furthermore, the liquid guiding part also includes a locking piece, which is connected to one end of the tube body and cooperates with the material cover.

[0013] Furthermore, a gap is left between the end surface of the liquid storage cylinder close to the operation panel and the tube body.

[0014] Furthermore, the extraction liquid structure also includes a conversion component and a monitoring component. The conversion component and the monitoring component are arranged on the same side of the lower end of the operation panel. One end of the tube body is connected to the conversion component, and the monitoring component is connected to the conversion component.

[0015] Furthermore, the extraction liquid structure also includes a handle, and the handle is connected to the material cover.

[0016] Compared with the prior art, the beneficial technical effects of the present invention are as follows: (I) The present invention sets a detachable filter disc in the powder cartridge, which, on the one hand, prevents the coffee powder in the powder cartridge from falling out, and on the other hand, when the powder cartridge needs to be cleaned, the powder cartridge can be cleaned by simply disassembling it, thus avoiding the need to disassemble the entire structure, which is convenient and quick. During the cleaning process, after the filter disc is removed, it can be rinsed with clean water, thus avoiding the residue of extremely fine powder.

[0017] (ii) The present invention adopts a structural design. After the powder cartridge is loaded, the protruding portion of the powder cartridge is directly placed on top of the liquid storage cartridge. This is simple and convenient and avoids the need to put hands into the liquid storage cartridge, thereby ensuring food safety.

[0018] (iii) By arranging a diverter plate in the powder cartridge and arranging the orifice of the tube body at the upper end of the diverter plate, when water flows out of the tube body, the water can flow evenly to the coffee powder through the diverter plate, so that the water and the coffee powder are fully contacted and mixed, thereby effectively improving the quality of the liquid and avoiding blockage of the water outlet orifice.

Any modification of the structure, change in the proportional relationship or adjustment of the size, without affecting the effect that the present invention can produce and the purpose that can be achieved, should still fall within the scope of the technical content disclosed by the present invention.

[0027] See also Figures 1 to 4 The extraction liquid structure of the coffee machine of this embodiment includes an operation panel 1 placed on the table. Preferably, the operation panel 1 is an intelligent operation display system with a touch screen using touch technology, which is compatible with and can realize switching of multiple languages. In addition, the four main items of project, cleaning, disinfection, and setting can be realized through the main interface of the touch screen. For example, in the project, multiple commonly used extraction parameters can be set as personal preferences to facilitate the next extraction, and automatic or manual drainage can be selected, giving customers a better choice. The cleaning and disinfection functions can facilitate customer use and better ensure food hygiene. For example, in the setting interface, real-time time, language, etc. can also be set, and instrument usage information and version information are recorded. During the production, cleaning, disinfection and other projects, the remaining time can also be displayed in real time through the main interface to increase the convenience of customer use.
