The box body 125 and the box bottom 123 are integrally formed, the milk powder outlet 126 is disposed at a lower portion of the box body 125 and extends to an edge of the box bottom 123, that is, a lower edge of the milk powder outlet 126 is flush with an edge of an upper surface of the box bottom 123, so that, during brewing, slipping of the milk powder will not be blocked. Certainly, the lower edge of the milk powder outlet 126 is not limited to being flush with the edge of the upper surface of the box bottom 123, as long as the water is not blocked from washing the milk powder in the box bottom during shaking and brewing. The longitudinal relative movement between the box body 125 and the box body support 122 is preferably piston movement, and in the piston type relative movement, the milk powder box 12 will have two working positions: when the piston type relative movement causes the milk powder outlet 126 to be blocked by an inner wall of the second connecting mechanism 124, in this preferred embodiment, the milk powder outlet 126 is blocked by an inner wall of the box body support 122, and the box body 125 and the box bottom 123 jointly form the milk powder placing cavity, this is the first working position of the milk powder box 12, that is, the state shown in FIG. 3, when the piston type relative movement causes the milk powder outlet 126 to be staggered from the inner wall of the second connecting mechanism 124 and no longer stick close to the inner wall of the box body support 122 and the milk powder outlet 126 is exposed to the space in communication with the inner cavity of the feeding bottle 11, that is, the milk powder outlet 126 is opened, the milk powder box 12 and the feeding bottle 11 form a milk powder channel in sealed isolation from the outside for brewing milk powder, at this point, from the feeding bottle 11 via the milk powder box 12 to the nipple, a milk channel in sealed isolation from the outside is formed inside, for the milk to be drunk, that is, the state shown in FIG. 4.

In order to further describe the structure of the milk brewing device 10, please refer to FIG. 2 and FIG. 3: the box body support 122 is provided thereon with two grooves 1221, the grooves 1221 extend to the lower portion from the upper port of the box body support 122 but do not lead to the lower port, the number of the grooves may also be one or three, four and so on, the two grooves 122 are both provided with a first clipping position 1223 and a second clipping position 1224, the two first clipping positions 1223 are at the same level on the box body support 122, and the two second clipping positions 1224 are also at the same level on the box body 122, where the second clipping positions 1224 are located at the bottom of the grooves 1221, and sizes of the two respective clipping positions of each groove 1221 are the same, and preferably, sizes of the four clipping positions are the same; more preferably, the four clipping positions are cylindrical, and the diameter thereof is greater than the transverse width of the grooves 1221 (described relative to the longitudinal depth). In order to achieve the piston type relative movement between the box body 125 and the box body support 122, the outer wall of the box body 125 is provided thereon with two support posts 1251 at the same level, and the two support posts 1251 can just be embedded into the two grooves 1221 respectively from the upper port of the box body support 122 and can slide up and down in the grooves, thereby achieving the piston type relative movement between the box body 125 and the box body support 122. The box body 125 and the box body support 122 are both cylindrical, and a relationship between an outer diameter of the box body 125 and an inner diameter of the box body support 122 satisfies that the outer wall of the box body and the inner wall of the box body support stick close to each other. The relative movement between the box body 125 and the box body support 122 causes the milk powder box 12 to have a first working position and a second working position: as shown in FIG. 3, when the support post 1251 is embedded into the first clipping position 1223, the lower port of the box body 125, that is, the edge of the box bottom 123 does not protrude beyond, and preferably, is flush with the lower port of the box body support 122, as the outer wall of the box body 125 and the inner wall of the box body support 122 stick close to each other, the milk powder outlet 126 located at the lower portion of the box body 125 is completely blocked by the inner wall of the box body support 122, the box bottom 123 and the box body 125 jointly form the milk powder placing cavity, it is the first working position, where the milk powder can be placed, and the milk powder placed is isolated from the water in the feeding bottle; as shown in FIG. 4, the box body 125 is pressed till the support post 1251 is embedded into the second clipping position 1224, the milk powder outlet 126 is staggered from the inner wall of the box body support 122, that is, the milk powder outlet 126 enters into the inner cavity of the feeding bottle 11, the water in the feeding bottle 11 can be combined with the milk powder in the milk powder box 12 through the milk powder outlet 126, that is, the milk powder box 12 and the feeding bottle 11 form a milk powder channel in sealed isolation from the outside for brewing the milk powder, and from the nipple via the milk powder box 12 to the feeding bottle II, a milk channel in sealed isolation from the outside is formed inside, for the milk to be drunk, and it is a second working position.

In a preferred solution, as shown in HG. 3, the first connecting mechanism 121 is an external thread that may match and connect an ordinary nipple, the height of the box body 125 is greater than the height of the box body support 122, to cause that, in the first working position and the second working position, and when switching is carried out between the two working positions, the first connecting mechanism 121 always protrudes beyond the upper port of the box body support 122, to ensure that the first connecting mechanism 121 is exposed.

As shown in F1G.19 to FIG. 21, the lower port of the box body 525 is provided with a second seal ring 528 moving with the box body, which is also "I"-shaped, but is not vertically symmetrical like the first seal ring 529, and is sleeved on a second flange 5251 extending outward from the lower port of the box body 525, the second seal ring 528 has a second upper end face and a second lower end face opposite the second upper end face, in the first working position, the second lower end face contacts the box bottom 523 and deforms, to achieve sealing between the milk powder placing cavity and the feeding bottle as well as the outside; and in the second working position, the second upper end face contacts an inner surface of the second connecting mechanism (which specifically contacts the first shoulder of the inner surface of the box body support 522) and deforms, to achieve sealing between the milk channel and the outside.

The milk brewing device 50 is substantially the same as the milk brewing assembly in Embodiment 2 and Embodiment 3 in structural design, and their main differences are as follows: as shown in FIG. 20 and FIG. 21, the second upper end face of the second seal ring 528 is provided withal least one round of first protrusion (two rounds in the figures) 5281, and the second upper end face and the second lower end face have a side face therebetween, from which it can be known that the side face is a circular surface, an upper edge of the circular surface is connected to the second upper end face, a lower edge is connected to the second lower end face, on a circular band where the side face gets close to the second lower end face, a boss 5284 extends out, and the second lower end face is sequentially provided with one round of second protrusion 5282 and one round of third protrusion 5283 from an inner ring to an outer ring. As shown in FIG. 20, in the first working position, the second protrusion 5282 contacts parts within the box bottom 523 and the leaks 5235 and deforms, to enhance sealing between the milk powder placing cavity and the inner cavity of the feeding bottle; the third protrusion 5283 contacts an upper surface of the third connecting mechanism 5231 and deforms, and the deformation quantity herein is less than that produced by the second protrusion for the box bottom, used for releasing pressure when the inner cavity of the feeding bottle has steam pressure, not to make water vapor enter into the milk powder placing cavity from the second protrusion. As in FIG. 21, in the second working position, the first protrusion 5281 contacts the first shoulder 5221 of the inner surface of the box body support 522 and deforms, to enhance sealing between the milk channel and the outside; the boss 5284 contacts the second shoulder 5222 and deforms, and as, in the process of assembling the milk powder box, the user may touch the side face of the second seal ring 528, mating of the boss with the second shoulder at this point avoids that the milk leaks out to wash the side face, resulting in contamination of the milk.

As shown in FIG. 19, in order to avoid that outside contamination enters into the second seal ring of the milk brewing device from where the box body 525 is connected to the box body support 522 by thread (specifically, as in FIG. 20, the contamination may enter into a space encircled by the second upper end face and the side face of the second seal ring, the boss 5284, the inner surface of the box body support 522 and the outer surface of the box body), one round of seal wall 5253 is specifically disposed on a surface between the external thread of the box body 525 and the first connecting mechanism 521, as well as a sealing ring 5253 that can be clipped on the seal wall. In the first working position, the sealing ring or the seal wall is just at the upper port of the box body support 522, to play a role of sealing herein, and thus the design of the seal wall 5253 and the sealing ring 5254 solves the above problems.

Preferably, upper and lower surfaces of the first seal ring 529 may also be designed as
