Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0031] As described in the background art, the mixing effect of the structure for assisting the mixing of coffee and water by the capsule is not good.

[0032] In order to solve this technical problem, the present utility model provides a flow guiding structure and a capsule shell, which are applied to the fields of coffee capsule preparation and brewing.

[0033] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings.

[0034] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0036] Example 1, please refer to Figures 1-5 , a flow guiding structure, which includes an outer shell 1. A first sealing film 8 is fixedly arranged at the top end of the outer shell 1. An outlet 2 is arranged at the bottom end inside the outer shell 1. A flow guiding assembly 3 is arranged around the outlet 2. A breakdown assembly 4 is arranged outside the flow guiding assembly 3. The breakdown assembly 4 is used to pierce the second sealing film 9, so that the mixture at the top flows into the inside of the flow guiding assembly 3. A second sealing film 9 fixedly connected to the outer shell 1 is arranged at the top end of the breakdown assembly 4. A sealing cavity is formed between the first sealing film 8 and the second sealing film 9, and coffee powder can be placed inside it to store the coffee powder.

[0037] Further, as shown in Figure 2 , Figure 3 and Figure 5 , the outlet 2 includes a discharge cylinder 21. A connection port is provided at the center of the inner bottom end of the outer shell 1, and the inside of the connection port is fixedly connected to the discharge cylinder 21. A plurality of through grooves 22 are provided on the discharge cylinder 21, and the through grooves 22 are used to allow the liquid to flow out of the outer shell 1. The discharge cylinder 21 plays a role in guiding the flow, avoiding the non-concentration of the liquid flow position.

[0038] Further, as shown in Figure 2 , Figure 3 and Figure 5 , the flow guiding assembly 3 includes a second flow guiding ring 32 fixed to the inner bottom end of the outer shell 1. The discharge cylinder 21 is located inside the second flow guiding ring 32. A plurality of flow guiding ports are provided at the top end of the second flow guiding ring 32, and the flow guiding ports are used to allow the liquid to flow onto the outlet 2 and then flow to the bottom end of the outer shell 1.

[0039] Further, as shown in Figure 2 , Figure 3 and Figure 5 , the flow guiding assembly 3 further includes a first flow guiding ring 31 located outside the second flow guiding ring 32. A space is formed between the first flow guiding ring 31 and the second flow guiding ring 32. The first flow guiding ring 31 is fixedly connected to the inner bottom end of the outer shell 1. A plurality of inclined grooves are provided at the top end of the first flow guiding ring 31, and the inclination of the plurality of inclined grooves all faces the second flow guiding ring 32. The inclined grooves are inclined. Through the inclined grooves, the liquid flowing from the periphery generates the power of rotation, so as to rotate around the second flow guiding ring 32 to further mix the coffee and improve the mixing effect.

[0040] Further, as shown in Figure 3 and Figure 5 , the breakdown assembly 4 includes a plurality of tip blocks 41 fixedly connected to the inner bottom end of the outer shell 1. The end of the tip block 41 is sharp, and at the same time its tip contacts the second sealing film 9. The tip block 41 positions the position of the flowing-in liquid, so that the mixture at the top end of the second sealing film 9 always flows in from the outside of the flow guiding assembly 3, so that all the liquid needs to pass through the flow guiding assembly 3, enabling the flow guiding assembly 3 to fully play its role. The plurality of tip blocks 41 are respectively located outside the first flow guiding ring 31. A flow guiding block 42 fixedly connected to the outer shell 1 is provided between the plurality of tip blocks 41. The flow guiding block 42 can play a role in assisting the mixing, making the liquid stay for a longer time and flowing through the gap between the flow guiding block 42 and the tip blocks 41.

[0041] Further, as shown in Figure 4As shown in the figure, several flow control blocks 43 fixedly connected to the outer shell 1 are provided outside several tip blocks 41 and flow guiding blocks 42. Several flow channels 44 are opened at the top ends of the flow control blocks 43. After the second sealing film 9 is pierced by the tip blocks 41, the liquid to be introduced will flow in through the inclined grooves only when it reaches a certain level, and is further mixed through the gap between the flow control blocks 43 and the flow channels 44 when outside.

[0042] Example 2, please refer to Figure 2 、 Figure 6 and Figure 7 , a capsule shell, several reinforcing strips 52 are fixedly arranged inside the outer shell 1 at the top of the second sealing film 9. Limiting blocks 51 fixedly connected to the inner wall of the outer shell 1 are arranged above the reinforcing strips 52. A filter net fixedly connected to the outer shell 1 is arranged above several of the limiting blocks 51. Coffee powder is placed on the filter net, which also serves to filter out larger particles of coffee powder. A mixing tray 6 is arranged between the limiting blocks 51 and the reinforcing strips 52. While the reinforcing strips 52 increase the structural stability of the outer shell 1, they cooperate with the limiting blocks 51 to restrict the installation of the mixing tray 6. A mixing port is arranged inside the mixing tray 6, and the mixing port is used to allow the mixture to flow onto the second sealing film 9.

[0043] Further, as shown in Figure 2 、 Figure 6 and Figure 7 , the mixing tray 6 includes an installation ring 61 located between the limiting blocks 51 and the reinforcing strips 52. An installation post 62 and a flow guiding plate 63 are arranged inside the installation ring 61. The installation post 62 is used to fix the flow guiding plate 63 and also serves to control the water flow. The installation ring 61 and the installation post 62 are fixedly connected through the flow guiding plate 63. The top end of the installation post 62 is semi-circular to prevent coffee powder or liquid from staying on it. The shape of the flow guiding plate 63 is spiral downward, and one end of the flow guiding plate 63 is above the other end.

[0044] Further, as shown in Figure 6 and Figure 7 , the mixing port includes a discharge plate 71 located between the two ends of the flow guiding plate 63. The two ends of the flow guiding plate 63 are fixedly connected through the discharge plate 71. Installation grooves are opened at the bottom end of the discharge plate 71. Mixing plates 72 are fixedly arranged on both sides inside the installation grooves. A movable plate 73 is hinged to the top end inside the installation grooves. The two mixing plates 72 are inclined towards the movable plate 73. The movable plate 73 hangs downward due to gravity without external force, contacting the two mixing plates 72 to block the path to the bottom end and prevent coffee powder from falling.

[0045] The use process of the diversion structure and the capsule shell provided by the present utility model is as follows:

[0046] When coffee needs to be brewed, by piercing the first sealing film 8, the liquid for brewing coffee is poured into the interior of the housing 1, so that it is mixed with the coffee powder on the filter screen. Then the mixture falls onto the flow guide plate 63 through the filter screen, and thus moves downward along the path of the flow guide plate 63 to its end. During the moving process, preliminary mixing is carried out, and then re-mixing is carried out through the two mixing plates 72. Then, the impact force of the flowing liquid flushes open the flap 73, causing it to turn upward, so that the mixture drops onto the second sealing film 9;

[0047] At this time, continue to inject liquid so that the second sealing film 9 is pushed downward due to the water pressure, thereby increasing the contact force with the tip block 41. The second sealing film 9 is punctured through the tip block 41, so that the liquid flows in. It is mixed outside the first flow guiding ring 31 through the flow control block 43 and the flow groove 44. After the liquid reaches a certain level, it flows into the space between the first flow guiding ring 31 and the second flow guiding ring 32 through the inclined groove. Due to the inclined setting of the inclined groove, kinetic energy is generated outside the second flow guiding ring 32 to make the liquid rotate and further mix, and then it flows out through the flow guiding port and the through groove 22.
