In particular, "adjacent" in this application refers to directions along a circle or a ring.
The first embodiment is as follows:
before explaining a filter assembly and a single cup capsule for increasing powder dissolution rate disclosed in the present invention in detail, it is necessary to explain the related technical concept. The invention is assembled vertically and coaxially with the components corresponding to the view shown in fig. 1, the axes of all the components overlapping and therefore being indicated by the axis 100.
One embodiment of a filter assembly and single cup capsule for enhancing powder dissolution is disclosed with reference to fig. 1-13.
Referring to fig. 1 to 5, in the present embodiment, a single-cup capsule includes: upwards offer open cup 5 for shield 5 open seal membrane 1 of cup, and coaxial the filter assembly who locates the cup 5 bottom, be provided with water diversion plate 2 between seal membrane 1 and the filter assembly. Wherein the cup body 5 comprises a side wall 52 and a deformable bottom 53 connecting the side wall 52 and extending transversely; the diameter of the side wall 52 decreases from top to bottom in the direction of the axis 100 of the cup 5. The side wall 52 and the bottom 53 enclose a containing cavity 501 for containing powdered drink. The central position of the bottom 53 is provided with a through hole 54 for the liquid to flow out, and a separation film 541 which is easy to puncture is embedded in the through hole 54. The upper end of the side wall 52 is annularly provided with a first holding part 51 for holding the water diversion plate 2 in a protruding way along the radial direction, and the joint of the side wall 52 and the bottom 53 is folded to form a second holding part 531 for holding the filtering component. The edge 211 of the water knock out panel 2 rests on and is fixed to the first holder 51. The water dividing plate 2, the side wall 52 and the filter assembly enclose a brewing space (not shown) in which beverage powder can be brewed. The sealing film 1 completely covers the upper surface of the water distribution plate and is used for completely isolating the single-cup capsule from the external environment so as to avoid polluting the beverage powder contained in the cup body 5.
Referring to fig. 1 to 4, the water collecting groove 21 is formed by annularly and downwardly recessing the inner side of the edge 211 of the water distribution plate 2, the water collecting groove 21 is annularly arranged to ensure any arrangement angle, and the pricking pins arranged on the capsule beverage machine can accurately prick into the water collecting groove 21. Two water injection nozzles (not shown) communicating with the water collecting tank 21 are vertically and downwardly disposed at a position deviated from the center of the water distribution plate 2, and it should be noted herein that the water injection nozzles should be disposed deviated from the first passage 452 formed by the guide cylinder part 45, so as to prevent water from directly entering the first passage 452 from the water injection nozzles without passing through the first crushing part. The water injection nozzles form water injection channels 214 through which the water supply flow passes through the water distribution plate 2 and to the water filtering assembly. Preferably, the water injection nozzles are arranged in a centrosymmetric manner with the circle center of the water distribution plate 2 as the center of symmetry, so that two water flows can form opposite flushing after flowing to the water filtering component through the water injection channel 214. In this embodiment, the water injection nozzle is disposed on the edge 211 of the water diversion plate 2 for increasing the distance of the water inlet of the water injection nozzle, thereby increasing the flow stroke of the water flowing to the water filter tray through the water injection channel 214, and increasing the opposite flushing effect of the water flowing. Furthermore, the water distribution plate 2 can be provided with more than two water injection nozzles, and the water flow passing through the water injection nozzles can effectively form the opposite flushing effect. The water injection nozzle comprises a water inlet and a water outlet from top to bottom in sequence, and the edge of the water inlet is convexly provided with a flow dividing protrusion 215 for improving the flow velocity of water flowing into the water injection nozzle.
Specifically, the annular area of the sealing membrane 1 covering the water collecting tank 21 is a puncture area 101, and a puncture needle arranged on the capsule beverage machine punctures the puncture area 101 of the sealing membrane 1 and injects water columns into the water collecting tank 21. When the water collection tank 21 is filled with water, the water flows into the water injection nozzle in the direction indicated by the arrow 600. The sum of the sectional areas of the water outlets of the water injection nozzles is equal to the sectional area of the water column injected into the water collection tank 21, so that the flow rate of the water flow passing through the water outlets is equal to the flow rate of the water column injected into the water collection tank 21. It should be noted that, the smaller the cross-sectional area of the water outlet, the greater the flow velocity of the water flow passing through the water outlet, so it is easy for those skilled in the art to find that the sum of the cross-sectional areas of the water outlets of the water injection nozzles may be smaller than the cross-sectional area of the water column injected into the water collection tank 21, and the brewing effect is better. In summary, it is sufficient that the sum of the sectional areas of the water outlets is not more than the sectional area of the water column injected into the water collection tank 21. Referring to fig. 4, as a reasonable deformation of the water diversion plate 2 in this embodiment, the water diversion plate 2a is recessed at the center to form a water injection groove 22, and a pricker penetrates the sealing film 1 and then extends into the water injection groove 22; meanwhile, the water distribution plate 2a is provided with a water guide 23 communicating the water injection tank 22 and the water collection tank 21 to guide the water injected into the water injection tank 22 into the water collection tank 21 and further into the water injection nozzles. The water injection groove 22 provided at the center of the water diversion plate 2a can satisfy the use requirement when the puncture needle is provided at the center of the single-cup capsule.
Referring to fig. 6 to 13, in the present embodiment, the filter assembly embedded in the bottom of the single capsule cup body 5 includes: a water filtering disc 4 and an airtight layer 3 covering the upper surface of the water filtering disc. The water filtering tray 4 further comprises a tray body 40, the center of the tray body 40 protrudes upwards to form a flow guide cylinder part 45, the flow guide cylinder part 45 surrounds to form a first channel 452 for water to flow downwards through the tray body 40, and the airtight layer 3 completely covers the upper end face 451 of the flow guide cylinder part 45 and is used for completely shielding the first channel 452, so that the beverage powder is completely isolated from the first channel 452, and the beverage powder is prevented from directly entering the first channel 452 to cause waste. The upper surface of the tray body 40 is provided with a first stirring and crushing part, and the first stirring and crushing part comprises a plurality of circles of convex ribs 42 which are arranged on the radial outer side of the flow guide cylinder part 45 and are distributed at intervals. The ribs 42 of two adjacent circles are distributed in a staggered manner, that is, as described with reference to fig. 7, the symmetry line of the ribs 42 of two adjacent circles forms an included angle α. It should be noted that the value of the angle α must not be 0, so that several turns of the ribs 42 are spaced to form a tortuous path for cutting and breaking lumps in the drink. The upper end surfaces 421 of the ribs 42 are arranged in a gradually increasing manner in the radial inward direction from the edge 41 of the filter disc 4, that is, the upper end surfaces 421 of the inner ribs 42 are higher than the upper end surfaces 421 of the outer ribs 42. The upper end surface 451 of the deflector tube portion 45 is located on a plane higher than the upper end surface 421 of any of the ribs 42, so that the ribs 42 are spaced to form a plurality of wavy channels (i.e. see arrows 300) which are staggered in height and point to the first channel 452. A plurality of ribs 411 are protruded radially and inwardly at intervals at the edge 41 of the tray body 40, and adjacent ribs 411 surround the tray body 40 together to form a water storage space 412 for receiving water flow flowing out from the water injection nozzle. The water flow from the water storage space 412 flows to the guide cylinder part 42 through the zigzag channel formed by the interval of the adjacent convex ribs 42 along the direction of the arrow 200, and due to the blocking effect of the side walls of the convex ribs 42 to the water flow, the water flow continuously impacts the side walls 422 of the convex ribs 42 in the flowing process, so that the stirring force of the water flow to the drink powder is increased, and the caking is broken by the reaction force of the convex ribs 42 to the caking.
Referring to fig. 10 and 11, in the direction of the axis 100 of the water filtering tray 4, the water flows from the edge 41 of the water filtering tray 4 in the direction of the arrow 300, gradually passes over the upper surface 42 of the rib 42 and flows to the first channel 452, and the side wall 422 of two adjacent circles of ribs 42 and the tray body 40 form a local brewing space 423 together. Because the local brewing space 423 has a constraint effect on the water flow, the water flow is constrained in the local brewing space 423, so that the flow speed of the water flow with the same flow in the local brewing space 423 is increased, the kinetic energy of the water flow constrained in the local brewing space 423 is improved, and the stirring force of the water flow on the beverage powder is further increased. When the water flow turns over the convex ribs 42 in the direction indicated by the arrow 300 and rises gradually to flow to the first channel 452, the complexity of the flow direction of the water flow is increased, the water flow can stir the beverage powder in multiple directions, and the dissolution rate of the beverage powder is improved; meanwhile, the water flow is gradually decompressed in the flowing process from low to high, and the diversity of brewing pressure is increased, so that the stirring force of the water flow on the beverage powder is improved.
Referring to fig. 6 to 13, the water filter tray 4 further includes: a puncturing flow guide structure 43 fixed in the first passage 452 and protruding downward from the water filtering tray 4. The guide structure 43 is pierced to form a guide boss 431 for supporting the airtight layer 3, and when the airtight layer 3 is pierced, the guide boss 431 supports the airtight layer 3 so as to prevent the airtight layer 3 from falling into the guide cylinder part 45 and blocking the first passage 452. The upper end surface of the guide boss 431 is not higher than the plane of the upper end surface 451 of the guide cylinder part 45. In this embodiment, the flow guiding protrusion 431 is a cross-shaped cylinder to form an axially disposed flow guiding groove 4311 in a longitudinal direction, and the flow guiding groove 4311 is used for guiding the water flowing into the first channel 452, so as to prevent the agglomeration existing in the water from blocking the first channel 452. As a reasonable modification of this embodiment, as shown in fig. 12, the upper end surface of the flow guide projection 431' of the water filter disc 4a may also be shaped like a piece, which is only required to support the punctured air-tight layer 3 and prevent the air-tight layer 3 from entering the first passage 452. The bottom end of the flow guide boss 431 protrudes downwards to form a puncturing part 433, and the puncturing part 433 forms a plurality of liquid outlet channels 4331 for drainage in the axis 100 direction of the water filtering disc. The puncturing portion 433 is provided with a drainage collar 432 projecting radially outwardly around the puncturing portion 433. The drainage convex ring 432 and the bottom of the cup body are enclosed to form a water outlet cavity 435, the puncturing part 433 is partially contained in the water outlet cavity 435, and the puncturing part 433 protrudes out of the lower end surface 4321 of the drainage convex ring 432. The flow directing collar 432 is provided with a plurality of openings 434 through which water can flow into the outlet cavity 435. The water flows through the gap 434 into the outlet cavity 435 in the direction of arrow 400 and out through the outlet channel 4331 in the direction of arrow 500.
Further, the water filtering disc 4 further comprises a second crushing part arranged inside the guide cylinder part 45, the second crushing part further comprises a plurality of sharp ribs 44 which radially and inwards protrude from the inner wall of the guide cylinder part 45 in an annular mode and are used for crushing agglomerates, and the sharp ribs 44 extend in the direction of the axis 100 of the guide cylinder part 45. The pointed ribs 44 are connected to each other to form a cross-section having an annular saw-tooth shape. It should be further noted that the pointed ribs 44 are connected to form the annular saw teeth for breaking the lumps, in this embodiment, the cross section of the pointed ribs 44 is triangular, as a reasonable deformation, the cross section of a single pointed rib 44 may also be rectangular or trapezoidal, and it is sufficient that the pointed ribs 44 can surround to form the annular saw teeth for cutting and breaking the lumps entering the first channel 452. Two adjacent pointed ribs 44 are connected in a circumferential direction and form a first crushing channel 441 together with the flow guide boss 431 in a surrounding manner, the agglomerates enter the first channel 452 and then pass through the first crushing channel 441, and the agglomerates are crushed and dissolved in water flow due to the fact that the agglomerates are extruded by the pointed ribs 44 in the first crushing channel 441. The length of the pointed rib 44 in the radial direction from the middle end (the middle end is the middle end along the axis 100 direction) to the bottom end gradually increases, and meanwhile, the bottom end of the pointed rib 44 is connected with the flow guide convex ring 432, and forms a second crushing channel 442 which is contracted from top to bottom towards the center of the disc body 40 together with the flow guide boss 431. The agglomerates enter the second crushing channel 442 after passing through the first crushing channel 441. The second crushing channel 442 is arranged in a manner of tapering towards a circle o, so that the second crushing channel can further crush the lumps which are not completely crushed in the first channel 441, and the dissolution rate is effectively improved. The first channel thus divides from the top 452 into a first crushing channel 441 and a second crushing channel 442.
As described with reference to fig. 12 and 13, the radially inward ends of the pointed ribs project upward along the axis 100 to form sharp pricks 443 for puncturing the air barrier 3. The water flow flows from edge 41 of water filter 4 to first channel 452, and the water flow exerts impact force on airtight layer 3 due to pressure; under the reaction force of the spikes 443 on the airtight layer 3, the spikes 443 annularly puncture the airtight layer 3 from bottom to top; as the water flow continues, the inner liner 3 is torn around the sharp pricks 443, and the water flow rushes into the first channel 452 (i.e. the inner liner 3 changes from the sealed state to the torn state shown in fig. 3', and the torn inner liner 3 wraps the diversion boss 431).
Referring to fig. 1 to 13, a detailed description of the application process of the present embodiment is provided, wherein a user places a single cup capsule in a capsule beverage machine during use. The puncture area 101 of the sealing membrane 1 is punctured by a puncture needle arranged on the beverage machine, water columns with certain pressure are injected into the water collecting tank 21 through a channel contained in the puncture needle, and after the water in the water collecting tank 21 is fully collected, the water streams flow to the water inlet of the water injection nozzle. In order to ensure that the pressure of the water flow flowing out of the water outlet of the water injection nozzle is kept unchanged, the sum of the sectional areas of the water outlets is not more than the sectional area of the injected water column. The water flow flows out from the water injection nozzles arranged on the water distribution plate 2 to form two opposite water flows (in the embodiment, the water distribution plate 2 is provided with two water injection nozzles, and according to the above, the water distribution plate can also be provided with more than two water injection nozzles, and the embodiment is explained by taking only two water injection nozzles as an example), because the diameter of the side wall 52 of the cup body 5 is gradually reduced from top to bottom along the axis 100 direction of the cup body 5, the two water flows firstly contact with the side wall 52 and flow downwards along the side wall 52 to form a tendency of impacting towards the circle center o of the water filter disc 4. The water flows from the side wall 52 into the water storage space 412, and the water storage space 412 has an opening directed toward the deflector tube section 45 for further directing the water flow toward the deflector tube section 45. The water flow passes through the zigzag channel formed by the adjacent convex ribs 42 from the water storage space 412 along the direction indicated by the arrow 200 and flows to the guide cylinder part 42, and due to the blocking effect of the side walls of the convex ribs 42 on the water flow, the water flow continuously impacts the side walls 422 of the convex ribs 42 in the flowing process, so that the stirring force of the water flow on the drink powder is increased, and the caking is broken by the reaction force of the convex ribs 42 on the caking; meanwhile, the water flows from the edge 41 of the filter disc 4 in the direction of the arrow 300, gradually turns over the upper surfaces 42 of the ribs 42 and flows to the first channels 452, and the side walls 422 of two adjacent circles of ribs 42 and the disc body 40 form the local brewing space 423 together. Because the local brewing space 423 has a constraint effect on the water flow, the water flow is constrained in the local brewing space 423, so that the flow speed of the water flow with the same flow in the local brewing space 423 is increased, the kinetic energy of the water flow constrained in the local brewing space 423 is improved, and the stirring force of the water flow on the beverage powder is further increased.
Furthermore, water flow passes through the upper surface of the water filtering disc 4 and is fully mixed and stirred with the drink powder to form the drink containing lumps. The beverage turns over the upper end face 451 of the guide cylinder part 45 and flows to the first channel 452, and the beverage exerts impact force on the airtight layer 3 due to pressure; so that the spikes 443 annularly pierce the airtight layer 3 from bottom to top under the reaction force of the spikes 442 on the airtight layer 3; under the continuous action of the impact force of the beverage, the airtight layer 3 is torn around the sharp spine 443 for a circle, and the beverage flows into the first channel 452. After the beverage passes through the first and second crushing channels 441 and 442, the lumps existing in the beverage are crushed by the pressing and cutting action of the pointed ribs 44. The flow guide convex ring 432 is fixed with the flow guide cylinder part 45 through a plurality of partition plates 436 which are radially arranged, and the flow guide convex ring 432 and the inner wall of the partition plate flow guide cylinder part 45 jointly form a second channel 453 leading to the lower surface of the disc body 40. The beverage breaks up through the ribs 44 and flows through the second channel 453 in the direction of arrow 400 and into the outlet cavity 435. Under the impact action of water pressure on the water filtering disc 4, the water filtering disc 4 moves downwards, so that the bottom 53 (belonging to a part of the cup body 5) of the cup body 5 is driven to deform, and the lower surface of the disc body 40 is attached to the bottom 53 of the cup body; meanwhile, the puncturing part 433 punctures the isolating membrane 541 embedded in the through hole 54 downwards, and the beverage cylinder flowing into the water outlet cavity 435 flows out of the single-cup capsule through the liquid outlet channel 4331 arranged on the puncturing part 433 and flows into the receiving cup.
Example two:
the difference between the filter assembly and the single cup capsule for increasing the powder dissolution rate disclosed in the present embodiment and the filter assembly and the single cup capsule for increasing the powder dissolution rate disclosed in the first embodiment is that:
referring to fig. 14 to 18, the first crushing portion further includes at least one flow guiding rib 47 disposed between any two circumferentially adjacent ribs 42. The flow guide ribs 47 point to the flow guide cylinder part 45 from the edge 41 of the water filtering disc 4 b; meanwhile, the flow guide ribs 47 are arranged in a bending manner and are uniformly distributed at intervals in the circumferential direction relative to the circle center of the water filtering disc 4 b; the guide ribs 47 are provided with a cut-out 471 at least at one inflection point. The flow guide ribs 47 are used for guiding the water flow to form a vortex pointing to the center of a circle, so that the stirring force of the water flow on the beverage powder is increased. It should be noted that, as shown in the accompanying drawings, the water filtering disc 4b is provided with 8 flow guiding ribs 47, and the flow guiding ribs 47 are arranged in a central symmetry manner with respect to the circle center of the water filtering disc 4b, and the flow guiding ribs 47 are used for guiding water flow to form a vortex, and the number of the flow guiding ribs does not need to be specifically limited.
As described with reference to fig. 15, the water falling to the water filter tray 4b flows from the water storage space 412 toward the guide cylinder part 45 in the direction indicated by the arrow 200; at the same time, the flow is guided by the guide ribs 47 in the direction indicated by the arrow 200a and forms a vortex. The formed vortex and the water flow flowing in the direction shown by the arrow 200 form impact, so that the caking existing in the beverage is broken, and the water flow can effectively and fully brew the beverage powder. When water flows in the direction shown by the arrow 200a, fine turbulence is generated at the inflection point of the flow guide rib 47, and the turbulence is difficult to break and agglomerate due to small impact force; in contrast, the turbulence exists at the inflection point of the guide rib 47 and makes a circular motion at the inflection point, so that the powdered drink is accumulated and lumps are generated at the corner. The flow guiding ribs 47 are provided with notches 471 at their corners, so that the water flow is released in the direction of the arrow 200b, thereby avoiding turbulence and agglomeration at the corners.
As described with reference to fig. 17 to 18, the filter assembly and the single cup capsule for increasing powder dissolution rate of the present embodiment are different from the filter assembly and the single cup capsule for increasing powder dissolution rate of the present embodiment in that: the tray body 40 is gradually raised from the edge 41 of the drain tray 4b toward the guide cylindrical portion 45. Under the impact action of water pressure on the water filtering disc 4b, the water filtering disc 4b moves downwards, so that the bottom 53 (belonging to a part of the cup body 5) is driven to deform, the lower surface of the disc body 40b is tightly attached to the bottom 53 of the cup body, and the disc body 40 and the bottom 53 of the cup body enclose to form an impact space 530. The lower surface of the disk body 40 is convexly provided with a third stirring and crushing part, the third stirring and crushing part comprises a plurality of circles of crushing elements 48 which are annularly distributed at intervals, and the crushing elements 48 are arranged on the lower surface of the disk body 40 and are positioned on the radial outer side of the drainage convex ring 432. Two circumferentially adjacent breaker elements 48 are spaced apart to form a third breaker channel 481. In this embodiment, the upper surface of the flow guiding convex ring 432 is disposed in a slope shape, and is used for guiding the water flow flowing out from the second channel 453 and flowing along the lower surface of the disc body 40, and the water flow passes through the third breaking channel 481 in the direction indicated by the arrow 400 and impacts the water filtering disc 4b and then flows toward the puncturing part 433 through the notch. After the caking is impacted on the crushing element 48, the caking can be further crushed under the reaction force of the crushing element 48 on the caking, and the dissolution rate of the powder is further effectively improved.
Example three:
the main differences between the filter assembly and the single cup capsule for increasing the powder dissolution rate disclosed in this embodiment and the filter assembly and the single cup capsule for increasing the powder dissolution rate disclosed in the first and/or second embodiments are:
referring to fig. 19 to 23, in the present embodiment, the draft tube part 45 has a race type cross section, and the draft collar 432 partially shields the lower end outlet of the draft tube part 45 to form the second passage 453. The cross section of the guide cylinder part 45 is designed to be a runway type, so that the water yield is effectively improved, and the water yield efficiency is improved.
The difference is also that: the upper end surfaces 421 of the ribs 42 are arranged in a staggered manner in the radial inward direction from the edge 41 of the filter disc 4 c. Referring to fig. 22 and 23, the ribs 42 arranged in a staggered manner and the tray body 40 surround to form a local brewing space 423, the water flow turns over the upper end surface 421 of the rib 42 along the direction indicated by the arrow 300, and the ribs 42 arranged in a staggered manner enable the water flow to generate height drop for multiple times, so that the complexity of the water flow is further increased, and the probability of occurrence of agglomeration is reduced.
In this embodiment, the cross-sectional area of the protruding rib 42 gradually decreases from bottom to top, so that the top of the protruding rib 42 can break larger lumps to some extent.
