Description

Technical Field

[0001] This invention relates to the field of capsule coffee beverage machine technology, specifically a fully sealed capsule extraction device for thorough mixing. Background Art

[0002] Capsule coffee machines work by pre-filling coffee powder into jelly-like plastic capsules, then filling them with nitrogen to preserve freshness. When you want coffee, simply place the capsule into the machine to brew it quickly and easily. The general process is as follows: First, open the capsule inlet cap, place the capsule inside, close the cap, and press the switch to begin brewing. During brewing, the capsule's outer membrane is pierced by a needle, and then heated water quickly enters the capsule under pressure. The coffee powder is extracted through the capsule's internal filter and flows into the coffee cup below, completing the brewing process.

[0003] To improve extraction efficiency, existing coffee capsules are generally designed with an opening at the bottom to facilitate the flow of coffee liquid during extraction. However, this results in poor sealing of the entire coffee capsule, making it prone to contamination and deterioration during long-term storage. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a fully sealed capsule extraction device for thorough mixing, so as to solve the problems mentioned in the background art.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A fully sealed capsule extraction device for thorough mixing includes a first support, a liftable lifting block inside the first support, a liftable extraction pressing block below the lifting block, a second support fixedly connected to the bottom of the first support, a third support fixedly connected inside the first support, and a slidingly engaged pin inside the third support.

[0007] The second support is provided with a sliding frame that is slidably engaged. One end of the sliding frame is provided with a handle, and the other end of the sliding frame is provided with a positioning hole. An extraction placement frame is fixedly connected above the sliding frame. The side of the extraction placement frame is provided with a rotating opening and closing edge. The inside of the extraction placement frame is provided with a placement cavity. The inside of the placement cavity is provided with an annular supporting inclined edge. The bottom of the placement cavity is provided with a through-hole liquid outlet groove.

[0008] The placement cavity contains a coffee capsule, which includes a capsule shell with an annular edge at the top. Inside the capsule shell is a cavity with a liquid outlet at the bottom. Inside the cavity are a flow guiding component, a filter membrane, and coffee powder arranged in sequence. A lower sealing membrane is provided above the liquid outlet at the bottom of the capsule shell, and an upper sealing membrane is provided at the top of the capsule shell. The upper end of the flow guiding component has an axially arranged upper flow guiding groove, and the lower end of the flow guiding component has a protruding tip with a threaded lower flow guiding groove inside the protruding tip.

[0009] Preferably, the first bracket has a rotatable threaded rod inside, and a motor is fixedly connected to the top of the first bracket. The motor shaft is fixedly connected to the threaded rod through a coupling. The threaded rod has a threaded slider that slides with the first bracket. The movable plate is fixedly connected to the slider.

[0010] Preferably, the second bracket is provided with a sliding groove, and a sliding block is fixedly connected below the sliding frame, with the sliding block slidingly engaging with the sliding groove.

[0011] Preferably, a first spring is sleeved on the outside of the pin. When the sliding frame is pushed to the innermost part of the slide groove, the positioning hole is coaxial with the pin, and the pin can be inserted into the positioning hole after it descends.

[0012] Preferably, the lifting block is fixedly connected to the moving plate, a second spring is provided between the lifting block and the extraction pressure block, an arc protrusion is provided below the extraction pressure block, a needle is provided inside the extraction pressure block, the needle is hollow inside, and a liquid inlet pipe is provided at the tail end.

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

[0014] The beneficial effects of this invention are:

[0015] This invention provides a fully sealed capsule extraction device for thorough mixing. Through improvements to the extraction structure and the coffee capsule body, it incorporates multiple flow guiding structures internally, which can better mix the coffee within the capsule. Furthermore, through a reasonable design of the coffee capsule body, the sealing performance of the coffee capsule is improved, reducing coffee capsule deterioration and internal contamination caused by the environment. Moreover, it can automatically position the coffee capsule during extraction, avoiding positional deviations that could lead to a decrease in extraction efficiency.

[0016] In use, the fully sealed capsule extraction device of this invention, which provides thorough mixing, causes the extraction block to descend and contact the top of the upper sealing film, squeezing the second spring to contract and the piercing needle to pierce the sealing film and enter the coffee powder. As the lifting block continues to descend, the extraction block begins to rise. After the extraction block rises and contacts the lifting block, it is pushed down by the lifting block, squeezing the upper sealing film and pushing the coffee capsule down. Because the supporting inclined side supports the outer side of the capsule shell, when the capsule shell is pushed down, the squeezing guide component descends, and the protruding tip pierces the lower sealing film and extends from the bottom of the capsule shell. After the coffee powder and water are mixed, they are filtered through the filter membrane and enter the guide component for mixing. The mixture is then guided through the upper guide channel into the lower guide channel, where it rotates and guides the flow. Finally, the mixture is discharged from the protruding tip into the beverage cup below. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figures 1 to 6 As shown, this embodiment provides a fully sealed capsule extraction device for thorough mixing, including a first support 1, a rotatable threaded rod 11 inside the first support 1, a motor 2 fixedly connected to the top of the first support 1, and the rotating shaft of the motor 2 fixedly connected to the threaded rod 11 through a coupling, and the motor 2 drives the threaded rod 11 to rotate synchronously.

[0027] The threaded rod 11 is provided with a threaded slider 12, which is slidably engaged with the first bracket 1. When the threaded rod 11 rotates, it drives the slider 12 to move and rise synchronously. The slider 12 is provided with a fixedly connected movable plate 13, which drives the movable plate 13 to move synchronously when the slider 12 rises and falls.

[0028] Furthermore, the bottom end of the first bracket 1 is provided with a fixedly connected second bracket 3, and the second bracket 3 is provided with a sliding groove 31. The first bracket 1 is provided with a fixedly connected third bracket 4, which is also fixedly connected to the second bracket 3. The third bracket 4 is provided with a slidingly engaged pin 41 inside, and a first spring 411 is sleeved on the outside of the pin 41. When there is no external force, the first spring 411 pushes the pin 41 to rise to the highest point. When the moving plate 13 descends from the highest point, it pushes the pin 41 to descend. After the pin 41 receives downward pressure, the first spring 411 contracts, and the pin 41 descends.

[0029] Furthermore, the movable plate 13 is provided with a fixedly connected lifting block 7, and a liftable extraction pressure block 71 is provided below the lifting block 7. The extraction pressure block 71 and the lifting block 7 are guided by a universal guide column for lifting and lowering. A second spring is provided between the lifting block 7 and the extraction pressure block 71. An arc protrusion 711 is provided below the extraction pressure block 71. A needle 72 is provided inside the extraction pressure block 71. The needle 72 is hollow inside and has a connected liquid inlet pipe 73 at its tail end.

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

[0031] Furthermore, a sliding frame 5 with a sliding fit is provided above the second bracket 3. One end of the sliding frame 5 is provided with a handle 51, and the other end of the sliding frame 5 is provided with a positioning hole 52. A sliding block 53 with a fixed connection is provided below the sliding frame 5. The sliding block 53 is slidably engaged with the slide groove 31. The sliding frame 5 is moved by pulling the handle 51. When the sliding frame 5 is pushed to the innermost part of the slide groove 31, the positioning hole 52 is coaxial with the pin 41. After the pin 41 descends, it can be inserted into the positioning hole 52.

[0032] The upper part of the sliding frame 5 is provided with a fixedly connected extraction placement frame 54. The side of the extraction placement frame 54 is provided with a rotatably connected opening and closing edge 541. The inside of the extraction placement frame 54 is provided with a placement cavity 542. The inside of the placement cavity 542 is provided with an annular support inclined edge 543. The bottom of the placement cavity 542 is provided with a through liquid outlet groove 55.

[0033] Furthermore, a coffee capsule 6 is provided inside the placement cavity 542. The coffee capsule 6 includes a capsule shell 61 with an annular edge at the top. The height of the top of the capsule shell 61 minus the height of the top of the placement cavity 542 is ≥5mm. A cavity is provided inside the capsule shell 61 with a liquid outlet at the bottom. A flow guiding component 63, a filter membrane 64, and coffee powder 65 are arranged sequentially inside the cavity. A lower sealing film 62 is provided above the liquid outlet at the bottom of the capsule shell 61 to effectively prevent contamination inside the coffee capsule 6. An upper sealing film 66 is provided at the top of the capsule shell 61, and the upper sealing film 66 is protruding.

[0034] Specifically, the flow guiding component 63 has an appearance similar to the hole. The upper end of the flow guiding component 63 is provided with an axially arranged upper flow guiding groove 631, and the lower end of the flow guiding component 63 is provided with a protruding tip 632. The protruding tip 632 is provided with a threaded lower flow guiding groove 633 inside.

[0035] Working principle:

[0036] In use, the sliding frame 5 is pulled out by the handle 51, the coffee capsule 6 is placed into the placement cavity 542, and then the sliding frame 5 is pushed into the innermost part of the slide groove 31. The beverage cup is placed below the sliding frame 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 pin 41 to descend. After the pin 41 receives the downward pressure, the first spring 411 retracts. After the pin 41 descends, it is inserted into the positioning hole 52.

[0037] After the extraction block 71 contacts the top of the upper sealing film 66, it compresses the second spring to contract, and the needle 72 pierces the sealing film 66 and enters the coffee powder 65. As the lifting block 7 continues to descend, the extraction block 71 begins to rise. After the extraction block 71 rises and contacts the lifting block 7, it is pushed down by the lifting block 7 to compress the upper sealing film 66 and push the coffee capsule 6 down. Since the supporting inclined edge 543 supports the outside of the capsule shell 61, when the capsule shell 61 is pushed down, it compresses the flow guide component 63 to descend. The protruding tip 632 pierces the lower sealing film 62 and extends from the bottom of the capsule shell 61. Then the needle 72 begins to enter water.

[0038] After coffee powder 65 is mixed with water, it is filtered through filter membrane 64 and enters the flow guiding component 63 for mixing. It is then mixed and guided through upper flow guiding channel 631 into lower flow guiding channel 633. The lower flow guiding channel 633 rotates and guides the flow, and finally it is discharged from the protruding tip 632 into the beverage cup below. After extraction is completed, the lifting block 7 rises and leaves.

[0039] Pull out the sliding frame 5 by pulling out the handle 51, rotate to open the opening and closing edge 541, take away the extracted coffee capsule 6, close the opening and closing edge 541, and repeat the above operation to perform the subsequent extraction operation of the coffee capsule 6.
