[0072] Please refer to Figures 1 to 11 In this embodiment, the switch driver 300 uses magnetic force to drive the switch assembly 13 to open the liquid outlet 111. 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 and mixing bin 100 and corresponds to the liquid outlet 111, and is used to close the liquid outlet 111. The switch driver 300 uses magnetic force to drive the switch assembly 13 to open the liquid outlet 111, which can avoid direct physical connection or contact between the switch driver 300 and the driving switch assembly 13, and can facilitate the removal of the powder storage and mixing bin 100 from the middle seat 21 to hold the powder to be prepared, or to clean the powder storage and mixing bin 100.

[0073] The movable part 131 is arranged at the lower side of the powder storage and mixing bin 100 , the upper end of the movable part 131 passes through the liquid outlet 111 of the powder storage and mixing bin 100 and is connected to the sealing cover 133 , and the middle seat 21 is provided with a through hole 211 for the lower end of the movable part 131 to be inserted.

[0074] The elastic member 132 acts on the movable member 131 to provide the movable member 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 and mixing bin 100 to close the liquid outlet 111. When the movable member 131 is acted upon by the driving 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 driving force can act on the movable member 131 in a direct physical contact manner, or in a non-physical contact manner.

The follower 134 can move upward when driven by a magnetic force. The switch driving member 300 includes a coil 31. The coil 31 is arranged at the periphery of the switch assembly 13. When energized, the coil 31 can generate a magnetic force to drive the follower 134 to overcome the elastic force of the elastic member 132 and move upward, thereby driving the movable member 131 and the sealing cover 133 to move upward together to open the liquid outlet 111. The coil 31 is arranged in the middle seat 21. The control power line connected to the coil 31 can enter the fuselage 200 through the middle seat 21 and connect with the main control circuit board. In this way, there is no need to connect the control power line at the bottom of the powder storage and mixing bin 100, which facilitates the disassembly and cleaning of the powder storage and mixing bin 100.

[0076] The main control circuit board is used to control the on and off of the current in the coil 31 to generate a magnetic field force or remove the magnetic field force. The generated magnetic field force can drive 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. After the magnetic field force 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.

[0077] In this embodiment, the follower 134 is an annular body. 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.

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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

When the external force on the movable part 131 is removed, the elastic part 132 provides a restoring elastic force to move the movable part 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 part 132 can also be other elastic elements, such as an elastic rubber ring. In other embodiments, the elastic part 132 can also be other elastic elements, such as an elastic rubber ring.

[0085] 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.

[0086] In this embodiment, a plug 126 is connected to the box cover 12, and the plug 126 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.

[0087] The outer surface of the bottom plate 112 of the powder storage box 11 is formed with a sleeve 1121 at the periphery of the liquid outlet 111, which is used to accommodate the spring, and the connecting section 1313 and the lower section 1312 of the movable member 131, and the sleeve 1121 is inserted into the through hole 211 of the middle seat 21. The sleeve 1121 can block the water-gouache 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-gouache mixture to flow along the axial direction of the liquid outlet channel 1315, and prevent the water-gouache mixture from splashing along the circumferential direction of the liquid outlet channel 1315.

[0088] 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 a positioning slot 214 is correspondingly provided on the middle seat 21 corresponding to the positioning support plate 113, and the powder storage and mixing bin 100 is installed, positioned and supported by inserting the positioning support plate 113 into the positioning slot 214. The powder storage and mixing bin 100 is installed, positioned and supported by inserting the positioning support plate 113 into the positioning slot 214, so that the powder storage and mixing bin 100 can be placed on the middle seat 21 more stably.

[0089] In this embodiment, the powder storage and mixing bin 100 includes a powder storage box 11 and a box cover 12 disposed on the powder storage box 11 , and a liquid inlet 121 is disposed on the box cover 12 .

[0090] 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.16As 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] like Fig.19 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.

[0095] like Fig. 20 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.

[0096] like Fig.21, 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.

[0097] 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.

[0098] 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.

[0099] In the powder dispensing machine 1 provided in the embodiment of the present application, a powder storage and mixing bin 100 is provided to store the powder to be prepared and to prepare the powder to be prepared, without the need to configure an independent powder storage bin and a mixing bin, and even more without the need to configure a complex powder dispensing device for the powder storage bin. The powder storage and mixing bin 100 can achieve the dual functions of storing the powder to be prepared and preparing the powder to be prepared, thereby simplifying the structure of the powder dispensing machine 1 and making the powder dispensing machine 1 convenient to carry. By providing a water inlet 201 for connection with an external water tank in the fuselage 200, without configuring a water tank in the fuselage 200 or on the side of the fuselage 200, the structure of the powder dispensing machine 1 is further simplified, and the volume of the powder dispensing machine 1 is reduced for easy carrying. When in use, the external water tank can be served as a water cup, which is small and convenient to use.

[0100] In addition, by arranging the switch driving component 300 in the middle seat 21, the switch driving component 300 drives the switch assembly 13 to open the liquid outlet 111 to allow the prepared water-powder mixture to flow out. The switch driving component 300 and the switch assembly 13 are designed to be separated, which can facilitate the disassembly and cleaning of the powder storage mixing bin 100.

[0101] The inventors of the present application 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 further made the following improvements to the powder storage and mixing bin.

[0102] like Fig. 22 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 previous 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. The specific structure can be found in the description of the powder storage and mixing bin 100 in the previous embodiment, which will not be repeated here.

[0103] 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 aforementioned embodiment lies in that: in this embodiment, the powder storage and mixing bin 100 also includes a partition bin 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.

[0104] Please also refer to Fig.23 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.

[0105] 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.

[0106] Please refer to Fig.24 In 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.

[0107] The powder storage and mixing bin 100a in this embodiment can be used to replace the powder storage and mixing bin 100 in the powder dispensing machine 1 in the aforementioned embodiment.

[0108] like Figure 25 to Figure 28 The second embodiment of the powder dispensing machine of the present application is shown. The structure of the powder dispensing machine 1b in this embodiment is basically the same as that of the powder dispensing machine 1 in the previous embodiment. The powder dispensing machine 1b includes a powder storage and mixing bin 100b, a body 200b, a switch assembly 13, and a switch driving member 300. The same parts are marked with the same reference numerals. The specific structure can be found in the description of the powder dispensing machine 1 in the previous embodiment, which will not be repeated here.

[0109] The structure of the powder dispensing machine 1b in this embodiment differs from that of the powder dispensing machine 1 in the aforementioned embodiment in that the setting position of the liquid inlet 121b of the powder storage and mixing bin 100b is different from that of the powder storage and mixing bin 100a / 100b, and accordingly, the setting position of the water outlet pipe of the heating component also changes.

[0110] In this embodiment, the powder storage and mixing bin 100a includes a powder storage box 11b, a box cover 12b disposed on the powder storage box 11b, and a switch assembly 13. The liquid inlet 121b is disposed on the powder storage box 11b, rather than on the box cover 12b. Specifically, the powder storage box 11b includes a bottom plate 112 and an annular peripheral wall 114b. The liquid inlet 121b of the powder storage box 11b is disposed on the peripheral wall 114b of the powder storage box 11b, and is used for inserting the water outlet pipe 41b of the heating assembly extending from the side of the body 200b, so that hot water flows into the powder storage box 11b and is mixed with the powder to be mixed. In order to facilitate the installation of the powder storage and mixing bin 100b on the powder mixing machine, the liquid inlet 121b is preferably in a longitudinal shape. In this way, when installing the powder storage and mixing bin 100b on the powder dispensing machine, the powder storage and mixing bin 100b can be pushed horizontally first, so that the water outlet pipe of the powder dispensing machine is inserted into the longitudinal liquid inlet 121b, and then the powder storage and mixing bin 100b is moved downward. The liquid inlet 121b is set to be longitudinally long to avoid the water outlet pipe blocking the downward movement of the powder storage and mixing bin 100b, which facilitates the installation of the powder storage and mixing bin 100b. In other embodiments, the liquid inlet 121b can also be set to a circular shape, and the water outlet pipe of the powder dispensing machine can be set to a retractable structure.

[0111] A middle seat 21 is provided on one side of the body 200b, and the powder storage and mixing bin 100b is provided on the middle seat 21. The powder dispensing machine 1b further includes a connecting cover assembly 600b, in which a motor is provided. The connecting cover assembly 600b is provided on the powder storage and mixing bin 100b and the body 200b, and the motor shaft 511 of the motor is used to communicate with the stirring element 14 (such as Figure 5 and Fig.10 The stirring element 14 is connected to the body 200b to drive the stirring element 14 to rotate. A heating component is arranged in the body 200b, and a water outlet pipe 41 of the heating component extends out of the side of the body 200b and is inserted into the liquid inlet 121b of the powder storage and mixing bin 100b, and hot water is injected into the powder storage and mixing bin 100b through the heating component.

[0112] A first connector 63 is provided at the bottom of the connection cover assembly 600, and the first connector 63 is electrically connected to the motor. A second connector 23 is provided at the top of the body 200, and the second connector 23 is electrically connected to the main control circuit board. The motor 51 is electrically connected to the main control circuit board by connecting the first connector 63 and the second connector 23. The detachable connection between the motor 51 and the main control circuit board 22 can be achieved through the connection cover assembly 600. The powder mixing machine 1b also includes a tray assembly 700, which is arranged below the powder storage and mixing bin 100b and is used to place a container such as a milk bottle to hold the prepared water-powder mixture.

[0113] The middle seat 21 is provided with a through hole 211 for inserting the lower end of the switch assembly 13. The middle seat 21 is also provided with a positioning slot 214 for inserting the positioning support plate 113 of the powder storage and mixing bin 100b. The positioning support plate 113 is inserted into the positioning slot 214 to install, position and support the powder storage and mixing bin 100, so that the powder storage and mixing bin 100b can be placed on the middle seat 21 more stably.

[0114] This application is not limited to the above implementation modes. Various changes can be made under the technical contents disclosed in the above implementation modes. Any equivalent structural transformation made by using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of this application.
