[0032] Before use, the first through hole 1 is blocked by the first sealing member 2, after the first sealing member 2 is removed, the storage box 200 is inserted into the first through hole 1, during the insertion process, the left end of the shell 3 enters the third through hole 14 first, because the outer diameter of the shell 3 is smaller than that of the third through hole 14, the shell 3 can easily enter, the wedge-shaped portion 12 first abuts against the inner wall of the third through hole 14 and elastically deforms a certain amount, the shell 3 continues to be inserted, and when entering the second through hole 13, it is guided by the guide groove 15 and the guide portion 16, that is, the third inclined surface 151 and the fourth inclined surface 161 are attached, which further makes the shell 3 more easily inserted into the first through hole 1, when the wedge-shaped portion 12 moves to the wedge-shaped groove 11, the wedge-shaped portion 12 restores the elastic deformation and is clamped into the wedge-shaped groove 11, at this time, the first straight surface 112 and the second straight surface 122 are attached so that the shell 3 and even the storage box 200 cannot be pulled out, realizing the stable connection of the bottle body 100 and the storage box 200, wherein the left end of the guide portion 16 can be appropriately extended, that is, the closer the left end of the guide portion 16 to the left end of the shell 3, the better the guiding effect.

[0033] As shown in Figure 3 and Figure 4As shown, in order to prevent the shell 3 from going too deep, an annular first protrusion 17 is provided on the outer wall of the shell 3, and the first protrusion 17 is located on the right side of the wedge-shaped portion 12. When the wedge-shaped portion 12 is clamped in the wedge-shaped groove 11, the end of the first protrusion 17 close to the first protrusion 10 is against the first protrusion 10, and an annular first sealing ring 18 is provided on the end surface of the first protrusion 10 away from the bottle body 100. The first sealing ring 18 is located between the first protrusion 10 and the first protrusion 17, forming an annular seal, so that the water in the bottle body 100 cannot flow out from the gap between the first through hole 1 and the outer peripheral wall of the shell 3.

[0034] like Figure 4 As shown, the feed port 4 in this embodiment is the discharge port 6, and the second sealing member 5 is the sealing film 7, making the structure simpler; Figure 5 As shown, the storage box 200 includes an entry end 19 for entering the inner cavity of the bottle body 100, that is, Figure 5 At the left end of the middle portion, the straight surface portion 31 is arranged close to the entry end 19, and a protective sleeve 20 is detachably mounted on the shell 3. The entry end 19 is located inside the protective sleeve 20. One of the inner wall of the protective sleeve 20 and the outer wall of the shell 3 is provided with an annular second protrusion 21, and the other is provided with an annular limiting groove 22, and the second protrusion 21 is clamped in the limiting groove 22; in this embodiment, the second protrusion 21 is arranged on the inner peripheral wall of the protective sleeve 20, and the limiting groove 22 is arranged on the outer peripheral wall of the shell 3. Before the storage box 200 is installed into the first through hole 1, the protective sleeve 20 must be removed first.

[0035] The storage box 200 in the present invention is filled through a pharmaceutical-grade production line. During the production and assembly process, a fixed amount of brewing product is stored in the storage box 200, and a fixed amount of water is stored in the bottle body 100, and the ratio of the two is ensured to be appropriate. The ratio varies accordingly according to the different brewing products. For example, if the brewing product is coffee, the ratio of coffee powder to water is preferably 1:18. The specific ratio values ​​of other brewing products are determined according to common sense or the recommended amount of the brewing product manufacturer, which will not be repeated here. In this way, there is no need to deliberately control the ratio between water and brewing product during brewing, which can save brewing time, make brewing more convenient, and ensure brewing. The taste of brewed drinks and milk powder can prevent the milk powder from being too thin or too thick and causing discomfort to the baby; when going out, you only need to carry the bottle body 100 and the storage box 200, which makes it easy to carry; before use, the first sealing member 2 blocks the first through hole 1, and the storage box 200 is not connected to the first through hole 1. When brewing is needed, you only need to remove the first sealing member 2 and connect the storage box 200 to the first through hole 1. During the process of inserting the shell 3 into the first through hole 1, the blade 9 on the cutter 8 breaks the sealing film 7 so that the discharge port 6 is connected to the inner cavity of the bottle body 100. At this time, the broken sealing film 7 is stuck in the angle between the first connecting portion 81 and the second connecting portion 82, as shown in FIG. Figure 4As shown, at this time the brewing material falls into the bottle body 100 and mixes with water, without opening or closing the bottle body 100 during the whole process, and the "one person one bottle" can be realized, which can reduce the contact between nursing staff and water and brewing material, avoid the exposure of water and brewing material to the air, reduce the risk of cross infection, and is simple to operate and not prone to errors. It is also suitable for medical staff to brew medicine for patients in the hospital, which can also reduce the risk of cross infection. In addition, in order to make the broken part of the sealing film 7 as large as possible, the blade part 9 should be appropriately wide, and the width of the blade part 9 to the width of the sealing film 7 is preferably 0.5 to 0.9; and when the wedge-shaped part 12 is clamped into the wedge-shaped groove 11, the first protrusion 17 abuts against the first protrusion 10, and the right side of the cutter 8 still has unbroken sealing film 7, that is, there is a margin between the cutter 8 and the right end of the discharge port 6, which not only prevents the sealing film 7 from completely separating from the shell 3, but also prevents the cutter 8 from colliding with the shell 3 before the first protrusion 17 abuts against the first protrusion 10, so that the shell 3 cannot advance.

[0036] Embodiment two:

[0037] As Figure 9 shown, another brewing device is provided in the embodiment, and the difference between the embodiment and embodiment one is that the feeding port 4 is arranged on one of the two end faces of the shell 3, and the second sealing member 5 is a end cap, which is threadedly connected with or clamped with the feeding port 4 by interference fit; in the embodiment, the feeding port 4 is arranged on the right end face of the shell 3, and after the brewing material is poured in, the second sealing member 5 is clamped in the feeding port 4.
