[0051] It should be understood that the specific implementation methods described herein are only used to explain the present application and are not used to limit the present application.

[0052] like Figures 1 to 7 Shown is the first embodiment of the rotary powder storage and mixing bin of the present application, which can be used in a powder mixing machine (e.g., a milk mixing machine for mixing formula milk powder, a coffee machine for mixing coffee, etc.) to store powder to be mixed and used to mix powder to be mixed.

[0053] In this embodiment, the powder storage and mixing bin 100 includes a powder storage box 11 , a box cover 12 disposed on the powder storage box 11 , and a switch assembly 13 .

[0054] The powder storage box 11 is used to store the powder to be prepared (not shown in the figure) and prepare the powder to be prepared. The bottom of the powder storage box 11 is provided with a liquid outlet 111. The box cover 12 is provided with a liquid inlet 121, and the liquid inlet 121 is used to supply hot water to flow into the powder storage box 11 and then be prepared with the powder to be prepared. The switch component 13 is arranged at the liquid outlet 111, and is used to close the liquid outlet 111 in the normally closed state to prevent the powder to be prepared stored in the powder storage box 11 from spilling through the liquid outlet 111; the switch component 13 can open the liquid outlet 111 under the action of external force to allow the water-powder mixture obtained by preparation to flow out.

[0055] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7 In this embodiment, the switch assembly 13 includes a movable part 131, an elastic part 132 and a sealing cover 133. The sealing cover 133 is arranged in the powder storage box 11 and is located above the liquid outlet 111, and is used to close the liquid outlet 111 to prevent the powder to be prepared stored in the powder storage box 11 from spilling through the liquid outlet 111 before preparation. The movable part 131 is arranged on the lower side of the powder storage box 11, and the upper end of the movable part 131 passes through the liquid outlet 111 of the powder storage box 11 and is connected to the sealing cover 133. The elastic part 132 acts on the movable part 131, and is used to provide the movable part 131 with an elastic force to pull down the sealing cover 133, so that the sealing cover 133 is close to the bottom of the powder storage box 11 to close the liquid outlet 111.

[0056] When the movable member 131 is acted upon by an external force, it can overcome the elastic force of the elastic member 132 and move upward, thereby driving the sealing cover 133 to move upward together to open the liquid outlet 111. The external force can act on the movable member 131 in a direct physical contact manner, or in a non-physical contact manner. The external force can be generated by a switch driver, and the external switch driver can generate an external force on the movable member 131 by manual operation, or by automatic operation such as electric control.

[0057] In this embodiment, the switch assembly 13 further includes a follower 134 connected to the movable member 131. The follower 134 is a magnet or can be attracted by a magnet. The follower 134 can move upward when driven by an external magnetic force. The external magnetic force can be generated by an external coil 20 (such as Figure 6 The magnetic force generated when the external coil 20 is energized drives the follower 134 to move upward, thereby driving the movable member 131 and the sealing cover 133 to move upward together to open the liquid outlet 111.

[0058] The driving method of the switch component 13 is not limited to this. In other embodiments, the switch component 13 can also be provided with a button, and the follower 134 is pressed upward to open the liquid outlet 111 by pressing the button, or a knob is provided, and the follower 134 is pressed upward to open the liquid outlet 111 by rotating the button.

[0059] In this embodiment, the follower 134 is an annular body, and in other embodiments, the follower 134 may also be a plurality of strip-shaped bodies and distributed at intervals along the circumference of the movable member 131. In this embodiment, the follower 134 is wrapped in the movable member 131, and in other embodiments, the follower 134 may also be arranged at the lower end of the movable member 131, or at the outer circumference or inner circumference of the movable member 131.

[0060] In this embodiment, the movable part 131 includes an upper section 1311, a lower section 1312, and a connecting section 1313 connected between the upper section 1311 and the lower section 1312. The upper section 1311 of the movable part 131 is provided with a first snap structure 1314, and the lower side of the sealing cover 133 is provided with a second snap structure 1331. The sealing cover 133 is connected to the upper section 1311 of the movable part 131 through the snap fit between the first snap structure 1314 and the second snap structure 1331. Through the snap fit, the sealing cover 133 and the upper section 1311 of the movable part 131 are detachably connected, which is convenient for assembly and the switch assembly 13 can be easily disassembled for cleaning.

[0061] The connecting section 1313 and the lower section 1312 are hollow, and a liquid outlet channel 1315 is formed therein. A connecting groove 1316 is provided on the outer peripheral surface of the connecting section 1313, and is used to connect the liquid outlet 111 with the liquid outlet channel 1315. In this way, when mixing, when the follower 134 is moved upward by an external force, and the movable member 131 and the sealing cover 133 are moved upward together to open the liquid outlet 111, the water-powder mixture obtained by mixing in the powder storage box 11 can enter the connecting groove 1316, and then flow to the container placed below the powder storage mixing bin 100, such as a milk bottle.

[0062] The first buckle structure 1314 includes a first buckle 1317 and a first slot 1318, the first slot 1318 is located at the lower side of the first buckle 1317, and the second buckle structure 1331 includes a second slot 1332 and a second buckle 1333, the second buckle 1333 is located at the lower side of the second slot 1332, and the sealing cover 133 is connected to the upper section 1311 of the movable member 131 through the snap fit between the first buckle 1317 and the second slot 1332, and the snap fit between the first slot 1318 and the second buckle 1333. By adopting double snap fit, the snap fit between the sealing cover 133 and the upper section 1311 of the movable member 131 can be made tighter, so as to prevent the movable member 131 from being loosened from the sealing cover 133 when the movable member 131 is reset under the elastic force of the elastic member 132.

[0063] In this embodiment, the first buckle 1317, the first slot 1318, the second slot 1332 and the second buckle 1333 are all annular in shape, and a convex ring 1334 is provided on the lower side of the sealing cover 133. The convex ring 1334 is located at the periphery of the second buckle 1333 and is spaced apart from the second buckle 1333. An annular groove 1335 is formed between the convex ring 1334 and the second buckle 1333, so that a double fit can be formed between the convex ring 1334 and the second buckle 1333 and the bottom of the powder storage box 11, thereby effectively preventing the powder to be prepared stored in the powder storage box 11 from leaking out from the liquid outlet 111 before preparation.

[0064] In this embodiment, the movable member 131 includes an upper section 1311, a lower section 1312, and a connecting section 1313 connected between the upper section 1311 and the lower section 1312. The follower 134 is located at the lower section 1312 of the movable member 131. The elastic member 132 is a spring, and the spring is sleeved on the periphery of the connecting section 1313. The powder storage box 11 includes a bottom plate 112 and an annular peripheral wall 114. The liquid outlet 111 is provided on the bottom plate 112 of the powder storage box 11. One end 1321 of the spring acts on the outer surface of the bottom plate 112 of the powder storage box 11, and the other end 1322 of the spring acts on the lower section 1312 of the movable member 131. When the external force on the movable member 131 is removed, the elastic member 132 provides a restoring elastic force to move the movable member 131 downward, thereby driving the sealing cover 133 to move downward together to close the liquid outlet 111. In this way, the powder storage and mixing bin 100 can store the powder to be prepared again after cleaning and drying for the next preparation. In other embodiments, the elastic member 132 can also be other elastic elements, such as an elastic rubber ring.

[0065] As a further improvement, in the present embodiment, an ear portion 1336 is formed on one side of the sealing cover 133, so that the sealing cover 133 can be conveniently removed from the movable part 131 by pulling the ear portion 1336, making the removal of the sealing cover 133 easier.

[0066] In this embodiment, the box cover 12 is connected with a plug 126, which is used to block the liquid inlet 121 when the powder storage and mixing bin 100 stores the powder to be prepared, so as to prevent foreign matter from entering the powder storage and mixing bin 100 and contaminating the powder to be prepared. Fig.15 When the powder to be prepared is used (as shown in the figure), the plug 126 can be pulled out so that one end 641 of the adapter water pipe of the external connection cover assembly 600 can be inserted, and hot water is injected through the adapter water pipe to prepare the powder to be prepared in the powder storage mixing bin 100. The peripheral edge of the box cover 12 is provided with a sealing ring 125, and the plug 126 is connected to the sealing ring 125. The plug 126 and the sealing ring 125 can be made of a silicone material. The peripheral edge of the box cover 12 is provided with a sleeve column 28, and the sleeve column 28 passes through the sealing ring 125 in the radial direction to prevent the sealing ring 125 from sliding and falling off along the axial direction of the box cover 12.

[0067] In this embodiment, a sleeve 1121 is formed on the outer surface of the bottom plate 112 of the powder storage box 11 at the periphery of the liquid outlet 111, so as to accommodate the elastic member 132, and the connecting section 1313 and the lower section 1312 of the movable member 131. The sleeve 1121 can block the water-powder mixture flowing from the powder storage box 11 to the liquid inlet 121 and entering the liquid outlet channel 1315 in the circumferential direction to guide the water-powder mixture to flow axially along the liquid outlet channel 1315, and prevent the water-powder mixture from splashing circumferentially along the liquid outlet channel 1315.

[0068] As a further improvement, in this embodiment, a positioning support plate 113 is provided at the bottom of the powder storage and mixing bin 100, and the positioning support plate 113 is arranged around the sleeve 1121. The positioning support plate 113 is used to insert the middle seat 21 (such as Fig.15 The positioning card slot 214 is provided on the middle seat 21, and the powder storage and mixing bin 100 is installed, positioned and supported by inserting the positioning support plate 113 into the positioning card slot 214, so that the powder storage and mixing bin 100 can be placed on the middle seat 21 more stably.

[0069] As a further improvement, in this embodiment, the lower side of the box cover 12 is rotatably connected to a stirring element 14, and a motor shaft 511 (such as a motor shaft 512 for an external motor) is provided on the box cover 12 corresponding to the stirring element 14. Fig.16 As shown in the figure, the motor shaft 511 is inserted into the insertion hole 122 so that the motor shaft 511 and the stirring element 14 can be inserted.

[0070] As a further improvement, in the present embodiment, the powder storage and mixing bin 100 further includes a mounting sleeve 15 and a connecting piece 16, both of which are arranged on the lower side of the box cover 12, the mounting sleeve 15 is fixed to the box cover 12, the connecting piece 16 is rotatably mounted in the mounting sleeve 15, the top of the stirring element 14 is connected to the lower part of the connecting piece 16, and the upper part of the connecting piece 16 corresponds to the insertion hole 122 and is provided with an axial hole 161 for inserting the external motor shaft. By providing the connecting piece 16, the stirring element 14 and the motor shaft 511 can be split, so that the motor will not be wetted when cleaning the powder storage and mixing bin 100, thereby improving the safety of use. In addition, the connecting piece 16 also has a certain damping effect, which can play a role in decelerating the motor shaft 511, preventing the motor shaft 511 from rotating too fast, so as to reduce the foam generated by the stirring element 14 during stirring.

[0071] Ears 151 are formed on both sides of the mounting sleeve 15, and the mounting sleeve 15 is fixed to the box cover 12 by fasteners 123 such as screws. A cap 124 is provided on the fastener 123. The cap 124 can be made of silicone.

[0072] In this embodiment, the stirring element 14 includes a rod body 141 and a stirring ring 142 connected to the lower part of the rod body 141. The number of stirring ring 142 is one, and the inner circumference of the stirring ring 142 is connected to the rod body 141 through a connecting rod 143. The stirring ring 142 is a Mobius ring, so that when stirring, the stirring ring 142 can make the water-gouache mixture flow along the ring surface of the Mobius ring, further reducing the generation of foam. The number and shape of the stirring ring 142 are not limited. In other embodiments, it can also be other numbers and shapes, for example, the number of stirring rings 142 can be multiple.

[0073] like Figure 8 FIG. 1 is a schematic diagram of the structure of the second embodiment of the stirring element of the present application. In this embodiment, the stirring element 14a includes a rod body 141a and a stirring ring 142a connected to the lower part of the rod body 141a. The number of stirring rings 142a is three and they are distributed in a triangular shape. The outer side of the stirring ring 142a is connected to the rod body 141a.

[0074] like Fig. 9 FIG. 1 is a schematic diagram of the structure of the third embodiment of the stirring element of the present application. In this embodiment, the stirring element 14b includes a rod 141b and a stirring ring 142b connected to the lower part of the rod 141b. The stirring ring 142b is connected to the rod 141a and is divided into two parts by the rod 141a.

[0075] like Fig.10, which is a schematic structural diagram of the fourth embodiment of the stirring element of the present application. In this embodiment, the stirring element 14c includes a rod body 141c and a stirring ring 142c connected to the lower part of the rod body 141c, and the top of the stirring ring 142c is connected to the bottom of the rod body 141a.

[0076] When the powder storage and mixing bin 100 is used, the box cover 12 is first opened, and the amount of powder required for a single preparation is poured into the powder storage box 11, and then the box cover 12 is closed, and the powder storage and mixing bin 100 is placed on the middle seat 21 (such as Fig.14 As shown), the powder dispensing machine 1 then injects an appropriate amount of hot water into the powder storage box 11 through the liquid inlet 121 of the box cover 12 to dispense the powder to be dispensed in the powder storage box 11. After the dispensing is completed, the switch assembly 13 is driven by external force to open the liquid outlet 111, so that the water-powder mixture obtained by the dispensing can flow out into the container below the powder storage mixing bin 100. When the amount of powder to be dispensed is relatively large, the amount of water required is also relatively large, and the amount of the water-powder mixture obtained by the dispensing may exceed the capacity of the powder storage mixing bin 100. In this case, the switch assembly 13 can be driven by external force to open the liquid outlet 111 when hot water starts to be injected into the powder storage box 11, so as to achieve dispensing while dispensing, so as to increase the amount of dispensable powder in the powder storage mixing bin 100, so that when the powder storage mixing bin 100 is used for dispensing milk, it can not only meet the small amount of milk dispensing requirements for newborn babies, but also meet the large amount of milk dispensing requirements for older children, and the powder storage mixing bin 100 has stronger versatility.

[0077] After the water-powder mixture has finished flowing out, the external force applied to the switch assembly 13 is removed, and the elastic member 132 provides a restoring elastic force to move the movable member 131 downward, thereby driving the sealing cover 133 to move downward together to close the liquid outlet 111. After being cleaned and dried, the powder storage and mixing bin 100 can store the powder to be prepared again for the next preparation.

[0078] In the powder storage and mixing bin 100 provided in the embodiment of the present application, a switch assembly 13 is provided at the liquid outlet 111 at the bottom of the powder storage box 11. The switch assembly 13 is used to close the liquid outlet 111 in the normally closed state to prevent the powder to be prepared stored in the powder storage box 11 from spilling through the liquid outlet 111, so that the powder storage and mixing bin 100 can realize the function of storing the powder to be prepared; the powder storage and mixing bin 100 is provided with a liquid inlet 121 on the box cover 12, so that the powder storage and mixing bin 100 also has the function of preparing the powder to be prepared. Compared with the prior art, when the powder storage and mixing bin 100 is applied to the powder preparation machine, it is not necessary to configure the powder preparation machine with an independent powder storage bin and mixing bin, and it is not necessary to configure a complex powder discharge device for the powder storage bin. The powder storage and mixing bin 100 can realize the dual functions of storing the powder to be prepared and preparing the powder to be prepared, so that the structure of the powder preparation machine can be simplified, making the powder preparation machine easy to carry.

[0079] The inventors of the present application have discovered through research that when the amount of powder to be prepared is small and the corresponding amount of water is small, the powder to be prepared is spread flat on the bottom of the powder storage box 11, and the small amount of water may not be able to completely prepare and dissolve the small amount of powder. In response to this, the inventors of the present application have made the following further improvements to the powder storage and mixing bin.

[0080] like Fig.11 The second embodiment of the powder storage and mixing bin of the present application is shown. The structure of the powder storage and mixing bin 100a in this embodiment is basically the same as that of the powder storage and mixing bin 100 in the first embodiment. The powder storage and mixing bin 100a also includes a powder storage box 11, a box cover 12 covered on the powder storage box 11, and a switch assembly 13. The same parts are marked with the same reference numerals, and the specific structure can be found in the description of the powder storage and mixing bin 100 in the first embodiment, which will not be repeated here.

[0081] The difference between the structure of the powder storage and mixing bin 100a in this embodiment and the powder storage and mixing bin 100 in the first embodiment is that: in this embodiment, the powder storage and mixing bin 100 also includes a partition 17 placed in the powder storage and mixing bin 100, and the stirring element 14a rotatably connected to the lower side of the box cover 12 has a different structure from the stirring element 14 in the first embodiment.

[0082] Please also refer to Fig.12 In this embodiment, the partition 17 is a hollow cylinder, and the inner diameter of the bottom end 171 of the partition 17 is smaller than the inner diameter of the bottom end 101 of the powder storage and mixing bin 100a. The partition 17 divides the inner space of the powder storage and mixing bin 100 into a powder storage area 102 located inside the partition 17 and an empty area 103 located outside the partition 17. When the powder storage and mixing bin 100a is in use, the powder to be prepared can be stored in the powder storage area 102, and the empty area 103 is separated by the partition 17 so that the powder to be prepared will not enter the empty area 103. In this way, the powder to be prepared can be concentrated in the partition 17 with a relatively small space, so that the powder to be prepared can be dissolved more fully by hot water preparation, which is particularly suitable for the case where the amount of powder to be prepared is small, such as the case of preparing milk for newborn babies.

[0083] The compartment 17 is trumpet-shaped, and the inner diameter of the bottom end 171 of the compartment 17 is smaller than the inner diameter of the top end 172 of the compartment 17. The bottom periphery of the compartment 17 extends outward to form an annular bottom plate 173. A handle 174 is provided on the top of the compartment 17 to facilitate taking the compartment 17 out of the powder storage box 11.

[0084] Please refer to Fig.13In this embodiment, the stirring element 14a rotatably connected to the lower side of the box cover 12 only includes a stirring rod, and no stirring ring is provided, so as to adapt to the smaller space in the compartment 17. Inclined stirring slopes 143a are formed on both sides of the lower end of the stirring rod. When the powder storage and mixing bin 100a uses the compartment 17, the structure of the stirring element 14a is not limited to this, and stirring elements of other structures can also be used, such as the stirring element 14b and the stirring element 14c in the aforementioned embodiment, as long as the lower end of the stirring element can be accommodated by the compartment 17.
