[0073] Referring to FIG. 8 , in this embodiment, the powder dispensing machine 1 further includes a switch driving component 300 .

[0074] Please refer to Figures 1 to 11. In this embodiment, the switch driver 300 uses a 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 a 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 drive 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 brewed, or to clean the powder storage and mixing bin 100.

[0075] The movable part 131 is arranged on 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. The middle seat 21 is provided with a through hole 211 for the lower end of the movable part 131 to be inserted.

[0076] 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 tightly attached 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 it can act on the movable member 131 in a non-physical contact manner. In this embodiment, the driving force is generated by the switch driver 300, and the switch driver 300 generates an external force acting on the movable member 131 by an electrical control method. In other embodiments, the switch driver 300 can generate a driving force acting on the movable member 131 by manual operation.

[0077] 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 a magnetic force. The switch driver 300 includes a coil 31. The coil 31 is disposed on 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 disposed within the center seat 21. The control power line connected to the coil 31 can pass through the center seat 21 into the body 200 and connect to the main control circuit board. This eliminates the need to connect the control power line at the bottom of the powder storage and mixing bin 100, facilitating disassembly and cleaning of the powder storage and mixing bin 100.

[0078] The main control circuit board controls the on / off switching of the current flowing into the coil 31 to generate or remove the magnetic field force. The generated magnetic field force drives the follower 134 upward, thereby driving the movable member 131 and the sealing cover 133 upward to open the liquid outlet 111. After the magnetic field force is removed, the elastic member 132 provides a restoring force to move the movable member 131 downward, thereby driving the sealing cover 133 downward to close the liquid outlet 111.

[0079] In this embodiment, the follower 134 is an annular body. In other embodiments, the follower 134 may be a plurality of strips and spaced apart along the circumference of the movable member 131. In this embodiment, the follower 134 is enclosed within the movable member 131. In other embodiments, the follower 134 may be disposed at the lower end of the movable member 131, or on the outer or inner circumference of the movable member 131.

[0080] In this embodiment, the middle seat 21 includes a lower seat body 212 and an upper seat body 213, and the switch driver 300 also includes a skeleton 32, an upper cover 33, a lower cover 34 and an outer tube 35 arranged between the upper seat body 213 and the lower seat body 212. The skeleton 32 is a hollow column, and the coil 31 is wound on the circumference of the skeleton 32. The upper cover 33 and the lower cover 34 are respectively arranged at the upper and lower ends of the skeleton 32. The outer tube 35 is arranged on the periphery of the coil 31 and is connected to the lower cover 34 and the lower cover 34.

[0081] As a further improvement, a night light control panel 215 is provided in the middle seat 21, and a night light (not shown in the figure) is provided on the lower side of the night light control panel 215. The lower seat body 212 of the middle seat 21 is provided with a light outlet window 2123 corresponding to the night light to illuminate the area below the middle seat 21 through the night light.

[0082] 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 facilitates assembly and allows the switch assembly 13 to be easily disassembled for cleaning.

[0083] The connecting section 1313 and the lower section 1312 are hollow, forming a liquid outlet channel 1315. A connecting groove 1316 is formed on the outer circumference of the connecting section 1313 for connecting the liquid outlet 111 with the liquid outlet channel 1315. Thus, when preparing the powder, when the follower 134 is moved upward by an external force, driving the movable member 131 and the sealing cover 133 to move upward together to open the liquid outlet 111, the water-powder mixture prepared in the powder storage box 11 can enter the connecting groove 1316 and then flow into a container placed below the powder storage and mixing bin 100, such as a feeding bottle.

[0084] The first snap-fit ​​structure 1314 includes a first snap-fit ​​1317 and a first slot 1318, with the first slot 1318 located below the first snap-fit ​​1317. The second snap-fit ​​structure 1331 includes a second slot 1332 and a second snap-fit ​​1333, with the second snap-fit ​​1333 located below the second slot 1332. The sealing cover 133 is connected to the upper section 1311 of the movable member 131 through the snap-fitting between the first snap-fit ​​1317 and the second slot 1332, and the snap-fitting between the first slot 1318 and the second snap-fit ​​1333. The double snap-fitting ensures a tighter fit between the sealing cover 133 and the upper section 1311 of the movable member 131, preventing the movable member 131 from becoming loose from the sealing cover 133 when the movable member 131 is reset under the elastic force of the elastic member 132.

[0085] In this embodiment, the first buckle 1317, the first slot 1318, the second slot 1332 and the second buckle 1333 are all annular, and a convex ring 1334 is provided on the lower side of the sealing cover 133. The convex ring 1334 is located on 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. In this way, 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, effectively preventing the powder to be prepared stored in the powder storage box 11 from leaking out from the liquid outlet 111 before preparation.

[0086] 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 in the lower section 1312 of the movable member 131. The elastic member 132 is a spring, and the spring is sleeved on the outer periphery of the connecting section 1313.

[0087] The powder storage and mixing bin 100 includes a powder storage box 11 and a cover 12 disposed on the powder storage box 11. The powder storage box 11 includes a bottom plate 112 and an annular peripheral wall 114. A liquid outlet 111 is disposed 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 acting on the movable member 131 is removed, the elastic member 132 provides a restoring force to move the movable member 131 downward, thereby driving the sealing cover 133 to move downward 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 use in the next preparation. In other embodiments, the elastic member 132 can also be other elastic elements, such as an elastic rubber ring. In other embodiments, the elastic member 132 may also be other elastic elements, such as an elastic rubber ring.

[0088] As a further improvement, in this embodiment, an ear portion 1336 is formed on one side of the sealing cover 133, so that the sealing cover 133 can be easily removed from the movable part 131 by pulling the ear portion 1336, making the removal of the sealing cover 133 easier.

[0089] In this embodiment, a plug 126 is connected to the box cover 12, and the plug 126 is used to seal the liquid inlet 121 of the powder storage mixing bin 100 when storing the powder to be brewed, so as to prevent foreign matter from entering the powder storage mixing bin 100 and contaminating the powder to be brewed. When the powder storage mixing bin 100 is placed in the middle seat 21 (as shown in Figure 15) of the powder brewing machine 1 for brewing, the plug 126 can be unplugged 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 brew the powder to be brewed in the powder storage mixing bin 100. The periphery 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 periphery of the box cover 12 is provided with a sleeve 28, and the sleeve 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.

[0090] A sleeve 1121 is formed on the outer surface of the bottom plate 112 of the powder storage box 11, surrounding the liquid outlet 111, for accommodating the spring, as well as the connecting section 1313 and lower section 1312 of the movable member 131. Sleeve 1121 is inserted into the through hole 211 of the center seat 21. Sleeve 1121 circumferentially blocks the water-gouache mixture flowing from the powder storage box 11 toward the liquid inlet 121 and into the liquid outlet channel 1315, thereby directing the mixture's axial flow along the liquid outlet channel 1315 and preventing it from splashing circumferentially along the liquid outlet channel 1315.

[0091] 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 provided on the middle seat 21 corresponding to the positioning support plate 113. The positioning support plate 113 is inserted into the positioning slot 214 to install, position, and support the powder storage and mixing bin 100. By inserting the positioning support plate 113 into the positioning slot 214, the powder storage and mixing bin 100 is installed, positioned, and supported, so that the powder storage and mixing bin 100 can be placed more stably on the middle seat 21.

[0092] In this embodiment, the powder storage and mixing bin 100 includes a powder storage box 11 and a box cover 12 provided on the powder storage box 11 , and a liquid inlet 121 is provided on the box cover 12 .

[0093] As a further improvement, in this embodiment, a stirring element 14 is rotatably connected to the lower side of the box cover 12, and an insertion hole 122 for inserting a motor shaft 511 of an external motor (as shown in Figure 16) is provided on the box cover 12 corresponding to the stirring element 14, so that the motor shaft 511 and the stirring element 14 can be connected.

[0094] As a further improvement, in this embodiment, the powder storage and mixing bin 100 further includes a mounting sleeve 15 and a connector 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, and the connector 16 is rotatably mounted in the mounting sleeve 15, the top of the stirring element 14 is connected to the lower part of the connector 16, and the upper part of the connector 16 corresponds to the insertion hole 122 and is provided with an axial hole 161 for inserting an external motor shaft. By providing the connector 16, the stirring element 14 and the motor shaft 511 can be separated, 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 connector 16 also has a certain damping effect, which can play a role in slowing down 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.

[0095] 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.

[0096] In this embodiment, the stirring element 14 includes a rod 141 and a stirring ring 142 connected to the lower portion of the rod 141. There is one stirring ring 142, and the inner circumference of the stirring ring 142 is connected to the rod 141 via a connecting rod 143. The stirring ring 142 is a Möbius strip. When stirring, the stirring ring 142 can cause the water-gouache mixture to flow along the annular surface of the Möbius strip, further reducing the generation of foam. The number and shape of the stirring rings 142 are not limited. In other embodiments, other numbers and shapes can be used, for example, there can be multiple stirring rings 142.

[0097] FIG19 is a schematic diagram of the structure of a second embodiment of a stirring element of the present application. In this embodiment, the stirring element 14a includes a rod 141a and a stirring ring 142a connected to the lower portion of the rod 141a. The stirring rings 142a are three in number and arranged in a triangular shape. The outer sides of the stirring rings 142a are connected to the rod 141a.

[0098] Figure 20 is a schematic structural diagram of a third embodiment of a 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 portion of the rod 141b. The stirring ring 142b is connected to the rod 141a and is divided into two parts by the rod 141a.

[0099] Figure 21 is a schematic structural diagram of a fourth embodiment of a stirring element of the present application. In this embodiment, the stirring element 14c includes a rod 141c and a stirring ring 142c connected to the lower portion of the rod 141c, with the top of the stirring ring 142c and the bottom of the rod 141a.

[0100] When the powder storage and mixing bin 100 is used, first open the box cover 12, pour the amount of powder required for a single brewing into the powder storage box 11, then cover the box cover 12, and place the powder storage and mixing bin 100 on the middle seat 21 of the powder brewing machine 1 (as shown in Figure 14), and then the powder brewing machine 1 injects an appropriate amount of hot water into the powder storage box 11 through the liquid inlet 121 of the box cover 12 to brew the powder to be brewed in the powder storage box 11. After the brewing is completed, the switch component 13 is driven by external force to open the liquid outlet 111, so that the water-powder mixture obtained by brewing can flow out into the container below the powder storage and mixing bin 100. When the amount of powder to be prepared is relatively large, the amount of water required is also relatively large, and the amount of water-powder mixture finally prepared may exceed the capacity of the powder storage mixing bin 100. In this case, when hot water starts to be injected into the powder storage box 11, the switch assembly 13 can be driven by external force to open the liquid outlet 111, so that liquid can be discharged while preparing the powder. In this way, the amount of powder that can be prepared in the powder storage mixing bin 100 can be increased, so that when the powder storage mixing bin 100 is used for preparing milk, it can not only meet the smaller milk preparation requirements of newborn babies, but also meet the larger milk preparation requirements of older children. The powder storage mixing bin 100 is more versatile.

[0101] After the 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 force to move the movable member 131 downward, thereby driving the sealing cover 133 downward to close the liquid outlet 111. After being cleaned and dried, the powder storage and mixing bin 100 can be used to store the powder to be prepared again for the next preparation.

[0102] 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 dispensed and to dispense the powder to be dispensed, 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 dispensed and dispensing the powder to be dispensed, thereby streamlining the structure of the powder dispensing machine 1 and making the powder dispensing machine 1 easy to carry. By providing a water inlet 201 for connection to an external water tank on the body 200, without configuring a water tank inside the body 200 or on the side of the body 200, the structure of the powder dispensing machine 1 is further streamlined, 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 relatively small and convenient to use.

[0103] In addition, by arranging the switch driving component 300 in the middle seat 21, the switch driving component 300 drives the switch component 13 to open the liquid outlet 111 to allow the water-powder mixture obtained by brewing to flow out. The switch driving component 300 and the switch component 13 adopt a separate design, which can facilitate the disassembly and cleaning of the powder storage mixing bin 100.

[0104] 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 this regard, the inventors of the present application have further made the following improvements to the powder storage and mixing bin.

[0105] FIG22 shows a second embodiment of a powder storage and mixing bin according to the present application. The structure of the powder storage and mixing bin 100a in this embodiment is substantially identical to that of the powder storage and mixing bin 100 in the aforementioned embodiment. Powder storage and mixing bin 100a also includes a powder storage box 11, a cover 12 disposed over the powder storage box 11, and a switch assembly 13. Identical parts are numbered the same. For detailed structure, please refer to the description of the powder storage and mixing bin 100 in the aforementioned embodiment and will not be repeated here.

[0106] 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 is 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.

[0107] Please refer to Figure 23 at the same time. In this embodiment, the partition 17 is hollow cylindrical, 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 internal 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, while 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 relatively small partition 17 so that the powder to be prepared can be dissolved more fully by hot water. This is particularly suitable for situations where the amount of powder to be prepared is small, such as when preparing milk for newborn babies.

[0108] 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.

[0109] 24 , in this embodiment, the stirring element 14d rotatably connected to the underside of the lid 12 includes only a stirring rod 141d without a stirring ring to accommodate the smaller space within the compartment 17. Inclined stirring slopes 143d are formed on both sides of the lower end of the stirring rod 141d.

[0110] When the powder storage and mixing bin 100a uses the partition 17, the structure of the configured stirring element 14a is not limited to this, and can also be combined with stirring elements of other structures, such as the stirring element 14b, stirring element 14c, and stirring element 14d in the aforementioned embodiments, as long as the lower end of the stirring element can be accommodated by the partition 17.

[0111] The powder storage and mixing bin 100a in this embodiment can replace the powder storage and mixing bin 100 in the powder dispensing machine 1 in the aforementioned embodiment.

[0112] As shown in Figures 25 to 28, a 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 substantially the same as that of the powder dispensing machine 1 in the aforementioned embodiment. The powder dispensing machine 1b includes a powder storage and mixing bin 100b, a body 200b, a switch assembly 13, and a switch driver 300. Identical parts are numbered the same. For the specific structure, reference may be made to the description of the powder dispensing machine 1 in the aforementioned embodiment, and no further details will be given here.

[0113] 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 the position 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.

[0114] In this embodiment, the powder storage and mixing bin 100b includes a powder storage box 11b, a 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 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 to insert the water outlet pipe 41b of the heating assembly extending from the side of the machine body 200b, so that hot water can flow into the powder storage box 11b and be mixed with the powder to be mixed. To facilitate installation of the powder storage and mixing bin 100b on the powder mixing machine, the liquid inlet 121b is preferably elongated. 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 from blocking the downward movement of the powder storage and mixing bin 100b, thereby facilitating 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.

[0115] 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 also 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 connect with the stirring element 14 (as shown in Figures 5 and 10) to drive the stirring element 14 to rotate. A heating assembly is provided in the body 200b, and a water outlet pipe 41 of the heating assembly 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. Hot water is injected into the powder storage and mixing bin 100b through the heating assembly.

[0116] A first connector 63 is provided at the bottom of the connecting 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 through the connection between the first connector 63 and the second connector 23. The connecting cover assembly 600 enables a detachable connection between the motor 51 and the main control circuit board 22. The powder dispensing machine 1b also includes a tray assembly 700, which is disposed below the powder storage and mixing chamber 100b and is used to place a container, such as a baby bottle, to hold the prepared water-powder mixture.

[0117] The middle base 21 is provided with a through hole 211 for inserting the lower end of the switch assembly 13. The middle base 21 is also provided with a positioning slot 214 for inserting the positioning support plate 113 of the powder storage and mixing bin 100b. By inserting the positioning support plate 113 into the positioning slot 214, the powder storage and mixing bin 100 is installed, positioned, and supported, so that the powder storage and mixing bin 100b can be placed more firmly on the middle base 21.

[0118] This application is not limited to the above embodiments. Various changes can be made within the technical content disclosed in the above embodiments. Any equivalent structural transformation made using the contents of this application specification and drawings, or directly or indirectly applied to other related technical fields, are also included in the scope of patent protection of this application.
