Description

Technical Field

[0001] The invention relates to the technical field of capsule coffee beverage machine equipment, in particular to a fully mixed fully sealed capsule extraction device. Background Art

[0002] The manufacturer of the capsule coffee machine pre-loads the coffee powder into a plastic capsule shaped like jelly, and then fills it with nitrogen to keep it fresh. When you need to drink coffee, put the capsule into the capsule coffee machine and use the capsule coffee machine to brew coffee simply, conveniently and quickly. Its usage process is as follows: first open the cover of the coffee machine capsule entrance, put the capsule into the coffee machine, cover the lid, press the switch to start brewing coffee. During the brewing process, the outer membrane of the capsule will be pierced by the needle first, and then the heated hot water will quickly enter the capsule under a certain pressure, and the coffee powder will be extracted through the filter inside the capsule and flow into the coffee cup below, thus completing the coffee brewing.

[0003] In order to improve the extraction effect, the existing coffee capsules are generally designed with an opening at the bottom to facilitate the outflow of coffee liquid during extraction. However, this will result in poor sealing of the entire coffee capsule, which is prone to contamination and capsule deterioration during long-term storage. Summary of the invention

[0004] In view of the shortcomings of the prior art, the object of the present invention is to provide a fully mixed and fully sealed capsule extraction device to solve the problems raised in the above background technology.

[0013] Preferably, the height of the top of the capsule shell minus the height of the top of the placement cavity is ≥5 mm.

[0014] Beneficial effects of the present invention:

[0015] The fully mixed fully sealed capsule extraction device of the present invention improves the extraction structure and the coffee capsule body, and is provided with multiple flow guide structures inside, so that the coffee in the coffee capsule can be better mixed. The reasonable design of the coffee capsule body improves the sealing performance of the coffee capsule, reduces the deterioration of the coffee capsule and the internal pollution caused by the environment, and can automatically position the coffee capsule during extraction to avoid the reduction of the extraction effect caused by position deviation.

[0016] When the fully mixed fully sealed capsule extraction device of the present invention is in use, the extraction pressing block descends and contacts the top of the upper sealing film, squeezes the second spring to contract, and the piercing needle pierces the upper sealing film to enter the coffee powder. When the lifting block continues to descend, the extraction pressing block starts to rise. After the extraction pressing block rises and contacts the lifting block, it is pushed down hard by the lifting block to squeeze the upper sealing film and push the coffee capsule down. Since the supporting bevel supports the outer side of the capsule shell, when the capsule shell is pushed down, the extruded guide component descends, and the protruding tip pierces the lower sealing film and extends out from the bottom of the capsule shell. After the coffee powder is mixed with water, it is filtered through the filter membrane and enters the guide component for mixing. It is mixed and guided through the upper guide groove and enters the lower guide groove. The lower guide groove performs rotational guidance and is finally discharged from the protruding tip into the beverage cup below. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The movable plate 13 descends, driving the lifting block 7 and the extraction block 71 to descend synchronously. The extraction block 71 contacts the top of the coffee capsule 6 and squeezes the second spring to contract, and the extraction block 71 starts to rise. After the extraction block 71 rises and contacts the lifting block 7, it is pushed down by the lifting block 7 to squeeze the coffee capsule 6.

[0034] Specifically, the appearance of the guide component 63 is similar to a hole. An axially arranged upper guide groove 631 is provided at the upper end of the guide component 63, a protruding tip 632 is provided at the lower end of the guide component 63, and a threaded lower guide groove 633 is provided inside the protruding tip 632.

[0035] Working principle:

[0036] When in use, the sliding rack 5 is pulled out by the handle 51, the coffee capsule 6 is placed in the placement cavity 542, and then the sliding rack 5 is pushed into the innermost part of the slide groove 31, and the beverage cup is placed under the sliding rack 5. The motor 2 is started to drive the moving plate 13 and the lifting block 7 to descend. When the moving plate 13 descends from the highest point, it pushes the latch 41 to descend. After the latch 41 receives the downward pressure, the first spring 411 contracts, and the latch 41 is inserted into the positioning hole 52 after it descends.

[0037] After the extraction pressing block 71 contacts the top of the upper sealing film 66, the second spring is squeezed to contract, and the puncture needle 72 pierces the sealing film 66 and enters the coffee powder 65. When the lifting block 7 continues to descend, the extraction pressing block 71 starts to rise. After the extraction pressing block 71 rises and contacts the lifting block 7, it is pushed down by the lifting block 7 to squeeze the upper sealing film 66 and push the coffee capsule 6 down. Since the supporting bevel 543 supports the outer side of the capsule shell 61, when the capsule shell 61 is pushed down, the flow guide component 63 is squeezed to descend, and the protruding tip 632 pierces the lower sealing film 62 and extends from the bottom of the capsule shell 61, and then the puncture needle 72 starts to take in water.

[0038] After the coffee powder 65 is mixed with water, it is filtered through the filter membrane 64 and enters the guide component 63 for mixing. Then, it is mixed and guided through the upper guide groove 631 and enters the lower guide groove 633. The lower guide groove 633 performs rotational guidance and finally is discharged from the protruding tip 632 into the beverage cup below. After the extraction is completed, the lifting block 7 rises and leaves.

[0039] The sliding frame 5 is pulled out by the handle 51 , the opening and closing edge 541 is rotated to open, the coffee capsule 6 after extraction is taken out, and the opening and closing edge 541 is closed. The above operation can be repeated to perform subsequent extraction operations of the coffee capsule 6 .
