Description

Technical Field

[0001] This utility model relates to the field of electrical technology, and more specifically, to a powder dispensing device, and also to an automatic brewing machine including the above-mentioned powder dispensing device. Background Technology

[0002] For families with infants and young children, preparing formula is a very normal but also very troublesome task. More and more consumers are opting for formula makers that can dispense measured amounts of formula. Existing formula makers with metered dispensing functions mainly consist of a powder hopper. However, the dispensing efficiency of current powder hoppers is not ideal, and the powder at the dispensing spout is prone to becoming damp, clumping, and clogging due to prolonged contact with outside air. This powder may then enter the bottle during the next formula preparation, affecting food quality and food safety.

[0003] In conclusion, how to effectively solve the problem of poor powder output from powder discharge machines is an urgent issue that needs to be addressed by those skilled in the art. Utility Model Content

[0004] In view of this, the first objective of this utility model is to provide a powder dispensing device that can effectively solve the problem of poor powder dispensing effect of the powder dispensing machine. The second objective of this utility model is to provide an automatic brewing machine including the above-mentioned powder dispensing device.

[0005] To achieve the first objective mentioned above, this utility model provides the following technical solution: a powder discharging device, comprising: a housing; a powder hopper, at least partially installed inside the housing, the powder hopper being used to store powdery materials, the powder hopper having an inlet and a discharge channel, the inlet being located at the top of the powder hopper, the discharge channel being located at the bottom of the powder hopper and having a powder outlet, the housing having an opening corresponding to the position of the discharge channel, for the powder from the discharge outlet to flow out of the housing; a discharging mechanism, including a powder discharging drive mechanism and a powder discharging screw, the powder discharging screw being installed inside the powder hopper and extending from the top of the powder hopper to the bottom of the powder hopper, the powder discharging drive mechanism driving the powder discharging screw to rotate relative to the powder hopper; and a sealing mechanism, installed outside the housing, at least a portion of the sealing mechanism being movable to a first state to seal the powder outlet or movable to a second state to open the powder outlet.

[0006] In the aforementioned powder discharging device, when discharge is required, the powder receiving container is placed so that its opening faces the powder discharging port. The sealing mechanism is activated, and the corresponding structure moves to the second state, opening the powder discharging port. Then, the powder discharging drive mechanism is activated, at which point the powder discharging screw rotates relative to the powder hopper. This relative rotation pushes the powder from the outlet into the receiving container. After receiving the powder, the powder discharging drive mechanism stops, and the sealing mechanism is activated, moving to the first state to seal the outlet before stopping the machine, thus completing the entire powder discharging process. In this device, automatic powder discharging is achieved through the discharging mechanism, improving convenience and allowing for easy control of the discharging rate. When discharging stops, the sealing mechanism closes the outlet to prevent powder from falling out; it also prevents the outlet from contacting humid air, thus avoiding powder deterioration and / or obstructed discharge. In summary, this powder discharge device can effectively solve the problem of poor powder discharge effect in powder discharge machines.

Detailed Implementation

[0018] This utility model discloses a powder discharge device to effectively solve the problem of poor powder discharge effect in powder discharge machines. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] In some embodiments, a powder dispensing device is provided, as shown in the attached figure. Figure 1 As shown, it mainly includes a shell 1, a powder hopper 2, a discharging mechanism, and a sealing mechanism. The powder stored in the powder hopper 2 can be milk powder, coffee powder, or bean powder, etc.

[0020] Powder hopper 2 is at least partially installed inside the housing 1. Powder hopper 2 is used to store powdery materials (which may be referred to as powder or powder body). Powder hopper 2 has an inlet 2-1 and a discharge channel 2-3, as described below. Figure 1 , Figure 5As shown, the powder hopper 2 mainly includes a hopper body 2-4 and a discharge channel 2-3. The top of the hopper body 2-4 is the inlet 2-1, and the discharge channel 2-3 is located at the bottom of the powder hopper 2, i.e., connected to the bottom of the hopper body 2-4. The discharge channel 2-3 has a powder outlet 2-2. The shell 1 has a shell opening 1-6 corresponding to the position of the discharge channel 2-3, so that the powder from the powder outlet 2-2 can flow out of the shell 1. It should be noted that the discharge channel 2-3 can be inside the shell 1. In this case, after the powder flows out from the powder outlet 2-3, it will pass through the shell opening 1-6 and flow to the outside of the shell 1; or the discharge channel 2-3 can pass through the shell opening 1-6, so that the powder outlet 2-2 is located on the outside of the shell 1, so that it passes through the shell opening 1-6 in the process of flowing to the powder outlet 2-2; or even the discharge channel 2-3 can be flush with the shell opening 1-6.

[0021] The discharge mechanism includes a powder discharge drive mechanism and a powder discharge screw 3. The powder discharge screw 3 is installed inside the powder hopper 3 and extends from the top of the powder hopper 3 to the bottom of the powder hopper 2. During rotation relative to the powder hopper 2, it drives the powder to flow downwards, i.e., from the discharge channel 2-3 to the powder outlet 2-2. The powder discharge drive mechanism drives the powder discharge screw 3 to rotate relative to the powder hopper 2 to meet the powder discharge conditions. Specifically, there are two possible examples: In one example, the powder hopper 2 remains stationary relative to the housing 1 of the powder discharge device, while the drive mechanism drives the powder discharge screw 3 to rotate relative to the housing 1, and thus relative to the powder hopper 2. In this case, the drive mechanism is the screw drive mechanism 7. In another example, the powder discharge screw 3 remains stationary relative to the housing 1, while the drive mechanism drives the powder hopper 2 to rotate relative to the housing 1, causing the powder hopper 2 to rotate relative to the powder discharge screw 3. In this case, the drive mechanism is the powder hopper drive mechanism 20. Both the screw drive mechanism 7 and the powder hopper drive mechanism 20 are generally motors.

[0022] The sealing mechanism is installed outside the housing 1, and at least a portion of the sealing mechanism is movable to a first state to seal the powder outlet 2-2 or to a second state to open the powder outlet 2-2. A specific example is as follows: Figure 21 , Figure 22 As shown, the blocking mechanism includes a material-blocking drive mechanism 5 and a baffle 4 disposed at the powder outlet 2-2. The baffle 4 has a material passage 4-2. The material-blocking drive mechanism can drive the baffle 4 to move so that the material passage 4-2 connects with the powder outlet 2-2 or blocks the powder outlet 2-2. The material-blocking drive mechanism can be a motor or other drive mechanism, and the baffle 4 can rotate or translate to connect or block the powder outlet 2-2. (See attached diagram) Figure 25As shown, the baffle 4 is restricted to sliding only relative to the housing 1 in the moving directions (X1, X2). It can slide from the second position to the first position along the X1 direction, where it is in the second state, thus opening the powder outlet 2-2, i.e., the material passage 4-2 is connected to the powder outlet 2-2; and it can slide from the first position to the second position along the X2 direction, where it is in the first state, thus blocking the powder outlet 2-2, i.e., the material passage 4-2 is not connected to the powder outlet 2-2. The material blocking drive mechanism 5 can be a motor, and a transmission mechanism is provided between the motor and the baffle 4. The specific transmission structure is a gear and rack transmission mechanism as shown in the attached figure.

[0023] In the aforementioned powder discharging device, when discharge is required, the powder receiving container is placed so that its opening faces the powder discharging port 2-2. The sealing mechanism is activated, and the corresponding structure moves to the second state, opening the powder discharging port 2-2. Then, the powder discharging drive mechanism is activated, at which point the powder discharging screw 3 rotates relative to the powder hopper 2. This relative rotation pushes the powder from the powder discharging screw 3, allowing it to flow out of the powder discharging port 2-2 and into the powder receiving container. After receiving the powder, the powder discharging drive mechanism stops, and the sealing mechanism is activated, moving to the first state to seal the powder discharging port 2-2 before stopping the machine, thus completing the entire powder discharging process. In the aforementioned powder discharging device, automatic powder discharging is achieved through the discharging mechanism, improving the convenience of powder discharging and facilitating the control of the powder discharging amount. When powder discharge stops, the sealing mechanism can close the powder outlet 2-2 to prevent powder from falling out. Simultaneously, the sealing mechanism also prevents powder outlet 2-2 from coming into contact with humid air and causing clumping, thus avoiding powder deterioration and / or poor discharge. In summary, this powder discharge device can effectively solve the problem of poor powder discharge from the powder discharger.

[0024] In some embodiments, as shown in the appendix Figure 2-10 As shown, a powder discharge screw 3 is provided for pushing powder out of the powder hopper 2. Specifically, the powder discharge screw 3 can be a feeding screw, as shown in the attached figure. Figure 4 As shown, materials are conveyed downwards. Specifically, see attached... Figure 2 , 4 The powder discharge screw 3 shown mainly includes a rod-shaped body 3-1 and a spiral blade 3-2, wherein the attached... Figure 2 The powder discharge screw 3 is compared with the attached Figure 4 The powder discharge screw 3 is set up inverted.

[0025] The spiral blade 3-2 is spirally wound around the rod-shaped body 3-1, and the two are fixed relative to each other. This allows the spiral blade 3-2 to rotate synchronously when the rod-shaped body 3-1 rotates. The rotation of the spiral blade 3-2 pushes the powder along the discharge direction to achieve discharge. The spiral blade 3-2 can be right-handed, but is not limited to this. The spiral blade 3-2, at least when rotating in one direction, can push the powder along the axial direction, as shown in the attached diagram. Figure 4 As shown, rotating around the direction indicated by the arrow can push the powder out in the discharge direction. The connection between the spiral blade 3-2 and the rod-shaped body 3-1 can be integrally formed or welded; there is no limitation on this.

[0026] In some embodiments, as shown in the appendix Figure 2 As shown, the powder discharge screw 3 may be further provided with a pusher part 3-3 on the basis of the rod-shaped body 3-1 and the spiral blade 3-2, and may or may not be provided with the multi-segment rod part 3-4 in any of the following embodiments.

[0027] The pusher section 3-3 is located in the bottom 3-1-1 area of ​​the rod-shaped body 3-1, for material output at the bottom 3-1-1. The bottom 3-1-1 of the rod-shaped body 3-1 can be understood as one end or the discharge end in the discharge direction. Specifically, the pusher section 3-3 is located between the bottom 3-1-1 of the rod-shaped body 3-1 and the adjacent spiral blades 3-2 in the extending direction of the rod-shaped body 3-1, as shown in the attached diagram. Figure 4 and Figure 10 As shown, when the discharge direction is downward, the lower end is the bottom 3-1-1. The pusher part 3-3 is located between the bottom surface 3-1-2 of the rod-shaped body 3-1 (or the plane where the bottom surface 3-1-2 is located) and the adjacent spiral blade 3-2 in the discharge direction to avoid the problem of poor discharge in the bottom 3-1-1 area.

[0028] The pusher part 3-3 is at least partially fixed relative to the rod-shaped body 3-1 and / or the helical blade 3-2, that is, the pusher part 3-3 may be fixedly connected only to the rod-shaped body 3-1, or it may be fixedly connected only to the helical blade 3-2; or it may be as shown in the attached figure. Figure 2 As shown, the pusher part 3-3 is not only fixedly connected to the rod-shaped main body 3-1, but also fixedly connected to the spiral blade 3-2, so as to achieve a better fixing effect, reduce the generation of gaps, and prevent material accumulation. (See attached diagram) Figure 2 As shown, the upper edge 3-3-3 of the pusher part 3-3 is connected to the spiral blade 3-2 and fixedly connected thereto; the inner edge 3-3-4 of the pusher part 3-3 is connected to the side of the rod-shaped body 3-1 and fixedly connected thereto.

[0029] Preferably, the pusher part 3-3 and the trailing edge 3-2-1 of the spiral blade 3-2 are offset in the circumferential direction of the rod-shaped body 3-1, so that when the powder discharge screw 3 rotates, the pusher part 3-3 and the trailing edge 3-2-1 of the spiral blade 3-2 work together, that is, in the direction of rotation, the trailing edge 3-2-1 of the spiral blade 3-2 is in front, and the pusher part 3-3 pushes the material behind, which can avoid the accumulation of material on the rear side of the trailing edge 3-2-1.

[0030] In the aforementioned powder discharge screw 3, in addition to the material pushing by the spiral blades 3-2, a pushing part 3-3 is added to the discharge end of the spiral blades 3-2. The pushing part 3-3 is located between the bottom surface 3-1-2 of the rod-shaped body 3-1 and the adjacent spiral blades 3-2. The pushing part 3-3 and the blade trailing edge 3-2-1 of the spiral blades 3-2 are staggered in the circumferential direction to avoid material accumulation at the bottom 3-1-1 of the powder discharge screw 3. The pushing part 3-3 and the blade trailing edge 3-2-1 of the spiral blades 3-2 are kept at an appropriate distance, allowing them to perform their respective operations on opposite sides of the rod-shaped body 3-1 without mutual interference. This ensures the discharge and pushing processes are carried out, thereby improving the discharge effect. Therefore, this powder discharge screw 3 can effectively solve the problem of poor discharge effect of the powder discharge screw 3.

[0031] In some embodiments, the pusher section 3-3 can be a pusher plate, as shown in the attached figure. Figure 3 As shown, the feeding section 3-3 includes a radially extending edge 3-3-1 extending radially along the rod-shaped body 3-1 and an axially extending edge 3-3-2 extending axially along the rod-shaped body 3-1. The radially extending edge 3-3-1 is flush with the bottom surface 3-1-2 of the rod-shaped body 3-1, while the axially extending edge 3-3-2 is flush with the radially outer side 3-2-2 of the spiral blade 3-2. This flush arrangement achieves a balance between optimal powder scraping effect and ease of use. (And in conjunction with the attached...) Figure 6 As shown, the radially extending edge 3-3-1 is used to approach or contact the upper side of the support rod 26 (its function is described in detail below) so as to scrape the powder on the support rod 26; while the axially extending edge 3-3-2 is used to approach or near the inner wall of the discharge channel 2-3 (its function is described in detail below) so as to scrape the inner wall of the discharge channel 2-3.

[0032] Preferably, the radially extending edge 3-3-1 may also be flush with the bottom surface 3-1-2 of the rod-shaped body 3-1, so that the bottom surface of the powder discharge screw 3 is a planar structure. In some embodiments, the radially extending edge 3-3-1 and the axially extending edge 3-3-2 may not be flush with the corresponding structure, as long as they can achieve their respective functions.

[0033] In some embodiments, as shown in the appendix Figure 10As shown, the pusher part 3-3 and the blade trailing edge 3-2-1 of the spiral blade 3-2 can be located on opposite sides of the rod-shaped body 3-1, so that the two are staggered as much as possible in the circumferential direction of the rod-shaped body 3-1, so that the pusher part 3-3 and the blade trailing edge 3-2-1 of the spiral blade 3-2 can maintain an appropriate distance, and can perform their respective work on opposite sides of the rod-shaped body 3-1 without mutual interference, ensuring the discharge and push of materials and reducing material accumulation.

[0034] In some embodiments, as shown in the appendix Figure 2 , 4 As shown, the powder discharge screw 3 is further provided with multiple rod sections 3-4 on the basis of the rod-shaped main body 3-1 and the spiral blade 3-2, and the pusher section 3-3 may or may not be provided in any of the above embodiments.

[0035] Specifically, the multi-segment rod 3-4 is located on the opposite side of the discharge direction of the spiral blade 3-2, as shown in the attached figure. Figure 4 As shown, the multi-segment rod 3-4 is positioned above the spiral blade 3-2, and the discharge direction of the spiral blade 3-2 is downward. (See attached diagram) Figure 9 As shown, and in conjunction with the appendix Figure 2 In use, the multi-segment rod 3-4 is located inside the hopper 2-4, while the spiral blade 3-2 is located inside the discharge channel 2-3. The multi-segment rod 3-4 can be used to feed material to the spiral blade 3-2, improving the turbulence effect on the powder and the discharge effect. The multi-segment rod 3-4 and the rod-shaped main body 3-1 are connected to form a closed structure, and the multi-segment rod 3-4 are not coplanar, that is, the segments of the rod are not located in the same plane, forming a non-coplanar structure.

[0036] By forming a closed structure, the structural strength can be significantly improved, making it less prone to deformation when the screw 3 rotates and pushes the powder. Furthermore, the non-coplanar structure creates multi-dimensional disturbance zones in space, improving material flowability and thus enhancing the discharge efficiency. The hollow structure in the middle of the closed structure reduces the rotational resistance of the screw 3. Therefore, by using a multi-segment non-coplanar and closed rod structure for pushing material, while ensuring structural stability and smooth rotation, material accumulation within the hopper 2-4 can be effectively prevented. Thus, the screw 3 with the aforementioned multi-segment rod 3-4 achieves a better discharge effect, effectively solving the problem of poor discharge performance in existing screw 3 models.

[0037] It should be noted that the non-coplanar structure described in this embodiment can be understood as follows: the multiple rods 3-4 are each regarded as line segments without width and thickness, and the projections of the multiple rods 3-4 on any plane do not coincide.

[0038] In some embodiments, the multi-segment rod 3-4 may include: at least one intermediate rod 3-4-1 and a connecting rod 3-4-2. See attached figure for details. Figure 2 , 4 As shown, the intermediate rod 3-4-1 includes a first end 3-4-11 and a second end 3-4-12 connected to each other. The first end 3-4-11 is located in front of the second end 3-4-12 in the direction of rotation when the powder discharge screw 3 rotates to discharge material; and the first end 3-4-11 is above the second end 3-4-12. The direction of rotation is shown in the attached diagram, with the arrow pointing in the direction of rotation and forward. During rotation, the front end is above the rear end, giving the intermediate rod 3-4-1 a downward pressing effect for better powder delivery.

[0039] Connecting rod 3-4-2 is located between the rod-shaped main body 3-1 and the intermediate rod 3-4-1, serving as an intermediate connection. It should be noted that multiple connecting rods 3-4-2 can be provided, as shown in the attached diagram. Figure 4 As shown, two connecting rods 3-4-2 (first connecting rod 3-4-21 and second connecting rod 3-4-22) are provided, and the two connecting rods 3-4-2 are arranged axially.

[0040] In some embodiments, as shown in the appendix Figure 2 , 4 As shown, the connecting rod 3-4-2 can include a first connecting rod 3-4-21 and a second connecting rod 3-4-22.

[0041] For details, see attached. Figure 4 As shown, the inner end of the first connecting rod 3-4-21 is connected to the rod-shaped main body 3-1, and the outer end is connected to the first end 3-4-11 of the intermediate rod 3-4-1. The inner end of the second connecting rod 3-4-22 is connected to the rod-shaped main body 3-1, and the outer end is connected to the second end 3-4-12 of the intermediate rod 3-4-1. The first connecting rod 3-4-21 and the second connecting rod 3-4-22 provide better stability to the intermediate rod 3-4-1.

[0042] Furthermore, the first connecting rod 3-4-21 can be arranged perpendicularly to the rod-shaped body 3-1; while the second connecting rod 3-4-22 is arranged at an angle relative to the rod-shaped body 3-1, with its outer end inclined towards the discharge direction compared to its inner end. By staggering these arrangements, the first connecting rod 3-4-21 can facilitate powder stratification and reduce rotational resistance, while the second connecting rod 3-4-22, being inclined towards the discharge direction, has a downward pushing effect.

[0043] In some embodiments, as shown in the appendix Figure 2 , 4 As shown, and in conjunction with the appendix Figure 9The powder discharge screw 3 also includes an extension rod 3-4-3, one end of which is connected to the second end 3-4-12 of the intermediate rod body 3-4-1, and the other end extends towards the spiral blade 3-2 and is located above the spiral blade 3-2, not within the discharge channel 2-3, but extending towards the spiral blade 3-2 to facilitate pushing the powder in the discharge direction and improve the discharge effect. (See attached...) Figure 9 As shown, the other end of the extension rod 3-4-3 forms a certain angle α with the middle rod 3-4-1 to achieve a better material pushing effect. The specific size of the angle α is not limited.

[0044] For details, see attached. Figure 9 As shown, the intermediate rod 3-4-1 and the extension rod 3-4-34-3 are both used to abut against the inner wall of the hopper 2-4. The intermediate rod 3-4-1 includes a first section 3-4-13 and a second section 3-4-14. The shape of the intermediate rod 3-4-1 matches the shape of the corresponding hopper 2-4. The hopper 2-4 includes a cylindrical hopper and a conical hopper. The first section 3-4-134 abuts against the inner wall of the cylindrical hopper, while the second section 3-4-14 and the extension rod 3-4-3 both contact the inner wall of the conical hopper, which is beneficial for scraping the powder off the hopper wall of the hopper 2-4.

[0045] In some embodiments, as shown in the appendix Figure 5 , 7 As shown, the discharge channel 2-3 is cylindrical and connected to the outlet of the hopper 2-4 for discharging materials. It is further integrated with... Figure 8 , 9 As shown, the spiral blades 3-2 of the powder discharge screw 3 extend from the bin 2-4 to the discharge channel 2-3 for discharge.

[0046] As attached Figure 5 , 6 As shown, and in conjunction with the appendix Figure 3 The powder outlet 2-2 of the discharge channel 2-3 is equipped with a support rod 26. The bottom surface 3-1-2 of the rod-shaped body 3-1 of the powder discharge screw 3 abuts against the support rod 26 for support. As mentioned above, the radially extending edge 3-3-1 is used to approach or contact the upper side of the support rod 26 to scrape the powder on the support rod 26; while the axially extending edge 3-3-2 is used to approach or near the inner wall of the discharge channel 2-3 to scrape the inner wall of the discharge channel 2-3.

[0047] In some embodiments, as shown in the appendix Figure 11-19 As shown, it also includes a platform 8 and a lifting drive mechanism (such as an attached...). Figure 13 (e.g., lifting motor 12, lifting screw 13, and lifting seat 9).

[0048] The powder dispensing side 15 of the powder compartment 2 is provided with a powder outlet 2-2, so that the milk powder in the compartment 2-4 of the powder compartment 2 can be discharged through the powder outlet 2-2 at the powder dispensing side 15. (See attached image) Figure 11 As shown, the powder outlet side 15 of the powder hopper 2 is the lower side of the powder hopper 2, with the powder outlet 2-2 facing downwards so that it can flow downwards under the action of gravity. Specifically, the powder outlet side 15 can be the lower side of the support tray 18, i.e., the contact surface 18-13, as described later.

[0049] The stage 8 is used to place the powder receiving container (not shown), which is positioned opposite the powder outlet 2-2, so that when the powder receiving container is placed on the stage 8, the container opening of the powder receiving container can face the powder outlet 2-2 to receive the powder flowing out of the powder outlet 2-2.

[0050] The lifting drive mechanism is connected to the platform 8 to drive the platform 8 closer to or further away from the powder outlet 2-2. The lifting drive mechanism drives the platform 8 to approach the powder outlet 2-2 by bringing the opening of the powder receiving container placed on the platform 8 into contact with the powder outlet side 15. This contact between the opening of the powder receiving container and the powder outlet side 15 ensures that the rim of the container opening forms a circumferential surround around the powder outlet 2-2, thereby guaranteeing that all the powder flowing out of the powder outlet 2-2 enters the container opening, i.e., all of it enters the powder receiving container. Even in the presence of convection air, it will not interfere with the powder flow at the powder outlet 2-2.

[0051] In some embodiments, as shown in the appendix Figure 11 As shown, in the powder dispensing device described above, during use, a powder receiving container (not shown) can be placed on the platform 8, with the container opening basically aligned with the powder outlet 2-2 (i.e., the powder outlet 2-2 is inside the container opening). Then, the lifting drive mechanism drives the platform 8 to rise towards the powder outlet 2-2 until the container opening abuts against the powder outlet side 15. At this point, the rim of the container opening surrounds the powder outlet 2-2, and the powder in the powder hopper 2 flows out from the powder outlet 2-2. The outflowing powder completely enters the receiving container through the container opening. Dispensing continues until the powder outlet 2-2 stops dispensing. Then, the lifting drive mechanism lowers the platform 8 to its original position, and the receiving container can be removed. In the powder dispensing device described above, the arrangement of the powder hopper 2 and the lifting drive mechanism ensures that the container opening abuts against the powder outlet side 15 to surround the powder outlet 2-2 during powder dispensing, effectively preventing lateral flow and overflow of powder and improving the powder receiving effect. In summary, this powder dispensing device can effectively solve the problem of poor powder dispensing performance in powder dispensing devices.

[0052] In some embodiments, as shown in the appendix Figure 12 , 13As shown, for ease of driving, the lifting drive mechanism can include a lifting motor 12, a lifting screw 13, and a lifting seat 9, where the lifting motor 12 can be a motor. One end of the lifting screw 13 is fixed to the lifting motor 12, and the extension direction of the lifting screw 13 is the same as the lifting direction of the platform 8. The lifting seat 9 is located on one side of the platform 8, which can avoid interfering with the lifting and lowering of the platform 8, making the structure simpler. The lifting seat 9 includes a connecting part 9-1, which has a threaded groove that mates with the lifting screw 13. That is, the lifting motor 12 and the lifting seat 9 form a screw-nut transmission mechanism through the lifting screw 13 and the threaded groove in the connecting part 9-1, so that when the lifting motor 12 drives the lifting screw 13 to rotate, based on the threaded engagement between the connecting part 9-1 of the lifting seat 9 and the lifting screw 13, the lifting seat 9 is driven to move along the extension direction (i.e., the axial direction) of the lifting screw 13. The lifting screw 13 extends in the same direction as the lifting platform 8, so the rotation of the lifting motor 12 can drive the lifting seat 9 to move along the lifting direction. It should be noted that a metal nut 9-6 can be integrated onto the lifting seat 9, and the metal nut 9-6 has threaded grooves.

[0053] Specifically, when the lifting motor 12 rotates forward, the lifting screw 13 rotates synchronously in the forward direction, correspondingly driving the lifting seat 9 to rise; while when the lifting motor 12 rotates in reverse, the lifting screw 13 rotates synchronously in the reverse direction, correspondingly driving the lifting seat 9 to fall. Therefore, in use, initially, the powder receiving container is placed on the platform 8. The lifting motor 12 starts rotating forward, the lifting seat 9 rises, and the platform 8 rises synchronously until the opening of the powder receiving container on the platform 8 touches the powder dispensing side 15, then the lifting motor 12 stops rotating. Powder is dispensed from the powder hopper 2. After powder dispensing is complete (which can be further explained later after the liquid supply device has finished supplying liquid), the lifting motor 12 reverses, the lifting seat 9 falls, and the platform 8 falls synchronously until it returns to its initial position, at which point the lifting motor 12 stops rotating.

[0054] In the above configuration, transmission is achieved through a screw and nut drive mechanism, enabling the lifting motor 12 to raise and lower the lifting seat 9. The screw and nut drive mechanism is a compact transmission component, and the lifting motor 12 is a relatively convenient drive source, resulting in a compact overall structure and good driving effect. Furthermore, the current of the lifting motor 12 can be detected to ensure it does not exceed a specified value. If it does, it indicates that the container opening is touching the powder outlet side 15, affecting further rotation of the lifting motor 12, and the lifting motor 12 will automatically stop. The current of the lifting motor 12 can be detected through its own structure or through an external current detection structure; this embodiment does not impose any limitations. Furthermore, the powder discharging device also includes a controller (not shown in the figure) to control the start and / or stop of the lifting motor 12 and other electrical components, improving the automation level of the powder discharging device.

[0055] Of course, in some examples, the lifting drive mechanism can also use a telescopic cylinder, which is set vertically. However, the telescopic cylinder requires an air source, so the overall setup cost is relatively high.

[0056] In some embodiments, as shown in the appendix Figure 12 , 13 As shown in Figure 16, for ease of arrangement and to make the structure simpler and more convenient, the connecting part 9-1 can be located on the side of the lifting seat 9 away from the platform 8. This allows the connecting part 9-1 and the platform 8 to be positioned on opposite sides, ensuring even force distribution on both sides. In some examples, the lifting seat 9 can also include a seat body 9-2, with the connecting part 9-1 located on the side of the seat body 9-2 away from the platform 8. In some examples, the lifting seat 9 can also include a seat body 9-2, with the connecting part 9-1 located on the side of the seat body 9-2 away from the platform 8. The connecting part 9-1 protrudes from the surface of the seat body 9-2 to form a protruding structure, extending away from the platform 8.

[0057] In the above configuration, the connecting part 9-1 is located on the side of the seat 9-2 away from the platform 8, so that the connecting part 9-1 and the platform 8 are respectively arranged on both sides of the seat 9-2, so that they are respectively subjected to external forces on both sides of the seat 9-2. This allows for lifting and lowering movement while achieving left-right balance. Compared with the platform 8 and the connecting part 9-1 being located on the same side, the above configuration has a better left-right balance effect, and thus is more stable during lifting and lowering movement.

[0058] In some embodiments, as shown in the appendix Figure 14 , 15 As shown, a gantry frame 10 can be further provided to facilitate the installation of structures such as the lifting platform 9. Specifically, the gantry frame 10 includes two uprights 10-1 and a first crossbeam 10-4 fixed to the top of the two uprights 10-1, so that the two uprights 10-1 and the first crossbeam 10-4 are combined to form a gantry structure. (See attached diagram) Figure 14 As shown, two columns 10-1 are arranged side by side. The left end of the first crossbeam 10-4 is connected to the left column 10-1, and the right end of the first crossbeam 10-4 is connected to the right column 10-1. The first crossbeam 10-4 and the column 10-1 are integrally formed and connected. Of course, they can also be connected by screws or other methods.

[0059] Combined with appendix Figure 12 , Figure 13As shown, the first crossbeam 10-4 has an installation structure for the end of the lifting screw 13 away from the lifting motor 12 to be rotatably mounted. A specific installation structure can be described as follows: The first crossbeam 10-4 has a cylindrical hole for the end of the lifting screw 13 to be inserted, allowing the lifting screw 13 to rotate. At this time, the end of the lifting screw 13 forms a shoulder. Two screw washers 16 are fixed to the first crossbeam 10-4 and pressed against both sides of the shoulder for fixation. The cylindrical hole and the two screw washers 16 combine to form the aforementioned installation structure. Each screw washer 16 includes a washer and a screw. The screw passes through the central hole of the washer to fix the washer to the first crossbeam 10-4.

[0060] Combined with appendix Figure 12 As shown, in the left-right direction, the lifting seat 9 is located between the two uprights 10-1 of the gantry frame 10. The seat body 9-2 is located on the side of the first crossbeam 10-4 facing the platform 8, where the side of the first crossbeam 10-4 facing the platform 8 refers to the side facing the user. (See attached image) Figure 12 As shown, the seat 9-2 is located on the rear side of the platform 8 and on the front side of the first crossbeam 10-4. By setting the lifting seat 9 between the two columns 10-1 and the seat 9-2 being located on the side of the first crossbeam 10-4 facing the platform 8, the lifting seat 9 is positioned inside the gantry 10, resulting in centered force distribution and more stable overall operation.

[0061] In some embodiments, as shown in the appendix Figure 13 , 15 As shown, the gantry frame 10 includes a second crossbeam 10-2 located between two columns 10-1, wherein the connecting part 9-1 is located directly above the second crossbeam 10-2, that is, between the first crossbeam 10-4 and the second crossbeam 10-2.

[0062] As attached Figure 14 As shown, two columns 10-1 are arranged side by side. The left end of the second crossbeam 10-2 is connected to the left column 10-1, and the right end of the second crossbeam 10-2 is connected to the right column 10-1. The second crossbeam 10-2 and the column 10-1 are integrally formed and connected. Of course, they can also be connected by screws or other methods.

[0063] The second crossbeam 10-2 is provided with a through groove 3-21 for the lifting screw 13 to pass through. The through groove 3-21 communicates with the threaded groove on the lifting seat 9, i.e., they are coaxially arranged, so that the upper end of the lifting screw 13 is fixed in the mounting structure of the first crossbeam 10-4, the lower end can pass through the through groove 3-21 of the second crossbeam 10-2, and the middle part passes through the lifting seat 9, with its external thread engaging with the threaded groove on the lifting seat 9. (See attached image) Figure 12 As shown, the threaded groove is integrated on the metal nut 9-6.

[0064] The lifting motor 12 is located directly below the second crossbeam 10-2, utilizing the lower space of the second crossbeam 10-2 to accommodate the lifting motor 12. The lifting screw 13 passes through the through slot of the second crossbeam 10-2 to connect with the lifting motor 12 located below the second crossbeam 10-2.

[0065] In the above embodiment, by setting the second crossbeam 10-2, an installation space for the lifting motor 12 is formed on the lower side of the second crossbeam 10-2, allowing the connecting part 9-1 to be staggered vertically on the upper side of the second crossbeam 10-2. This facilitates the accommodation and installation of the lifting motor 12, resulting in a more compact overall structure. Furthermore, the lower placement of the lifting motor 12 improves the stability of the overall structure and helps maintain the balance of forces on the gantry frame 10 when the lifting seat 9 drives the platform 8 to rise. Additionally, without affecting the lifting mechanism, the lifting seat 9 can be placed parallel to the lifting motor 12 at approximately the same height (instead of being placed above the lifting motor 12). This reduces the minimum height and maximum lifting height of the platform 8, lowering the overall height of the powder dispensing device, which is beneficial for miniaturization and saves space.

[0066] Of course, in some examples, the lifting motor 12 can also be installed on the first crossbeam 10-4 (not shown in the figure). In this case, too much space is needed on the upper side of the first crossbeam 10-4 to install the lifting motor 12, which will lead to problems such as inconvenient installation and poor stability.

[0067] In some embodiments, such as Figure 12 , 13 As shown in Figure 16, the lifting drive mechanism also includes a guide rod 14. The lifting seat 9 has a guide groove 9-3 through which the guide rod 14 passes, so as to guide the lifting seat 9 through the guide rod 14 to ensure the smooth lifting of the lifting seat 9. (See attached figure) Figure 12 , 13 As shown, the guide rod 14 is arranged parallel to the lifting screw 13 to guide the lifting seat 9 in the lifting direction. The guide rod 14 can be a cylindrical rod, but is not limited to any particular type. Specifically, one or more guide rods 14 can be provided; this is not restricted.

[0068] In some examples, it can also be as shown in the appendix. Figure 12 , 13 As shown, each is equipped with two guide rods 14, which are respectively positioned on the left and right sides of the lifting screw 13, as shown in the attached diagram. Figure 16 As shown, guide rods 14 can be provided on both sides of the connecting part 9-1 in the left and right directions. By guiding the lifting screw 13 on both sides, the force on both sides can be evenly distributed, thus making the lifting more stable.

[0069] In some embodiments, as shown in the appendix Figure 14 As shown, the gantry frame 10 also includes a bottom beam 10-3, which connects to the bottom 3-1-1 of the two uprights 10-1. The bottom beam 10-3 can extend to form an integral structure with the second crossbeam 10-2, thereby increasing the overall strength of the gantry frame 10. In particular, the bottom beam 10-3 further supports the second crossbeam 10-2 to ensure its support strength and better support the lifting motor 12. Of course, in some examples, the bottom beam 10-3 may not extend to the second crossbeam 10-2.

[0070] As attached Figure 14 As shown, two columns 10-1 are arranged side by side, the left end of the bottom beam 10-3 is connected to the left column 10-1, and the right end of the bottom beam 10-3 is connected to the right column 10-1. The bottom beam 10-3 and the column 10-1 are integrally formed and connected. Of course, they can also be connected by screws or other methods.

[0071] As attached Figure 12 , 14 As shown, the two ends of the guide rod 14 are fixed to the first crossbeam 10-4 and the bottom beam 10-3 respectively, so as to fix the guide rod 14 through the first crossbeam 10-4 and the bottom beam 10-3. The guide rod 14 is generally a cylindrical rod. The bottom beam 10-3 has a cylindrical hole that mates with the guide rod 14 for insertion. The first crossbeam 10-4 has a cylindrical hole that mates with the guide rod 14 for insertion. The upper side of the first crossbeam 10-4 has a screw washer 16 to press and position the upper end of the guide rod 14.

[0072] In some embodiments, as shown in the appendix Figure 18 The platform 8 can include a bracket 8-1 and a platform 8-2, wherein the platform 8-2 is mounted on the bracket 8-1, and the upper side of the platform 8-2 forms a loading surface for placing powder receiving containers. The bracket 8-1 is used to support the platform 8-2 and is mounted on the lifting seat 9.

[0073] In some embodiments, as shown in the appendix Figure 19As shown, the bracket 8-1 includes a connecting seat 8-11, a base 8-12, and a connecting handle 8-14. The connecting seat 8-11 is fixed to the side of the lifting seat 9 facing the platform 8, and screw holes are provided on the connecting seat 8-11 for fixing it to the lifting seat 9 with screws. The base 8-12 supports and limits the position of the platform 8-2. The base 8-12 is annular, with a support surface on its upper side to support the lower side of the platform 8-2. A protrusion is formed on the outer side of the support surface, extending along the edge in an annular shape to form a limiting groove that mates with the platform 8-2. This protrusion limits the platform 8-2, preventing lateral movement and stabilizing it on the base 8-12. It also facilitates easy removal for cleaning the platform 8-2. The connecting handle 8-14 connects the connecting seat 8-11 and the base 8-12 to transmit the supporting force.

[0074] The above-mentioned design not only facilitates the placement and removal of the tabletop 8-2, making it easier to clean, but also facilitates the connection between the bracket 8-1 and the lifting seat 9 via the connecting seat 8-11.

[0075] In some embodiments, in conjunction with the appendix Figure 18 , 19 and appendix Figure 11 As shown, the device includes a housing 1, which covers the outside of the lifting drive mechanism. The powder hopper 2 is at least partially installed inside the housing 1. An opening is provided on the housing 1 corresponding to the powder outlet 2-2. A platform 8-2 and a base 8-12 are located outside the housing 1, and a connecting seat 8-11 is located inside the housing 1. The housing 1 has a lifting groove 1-8 extending in the lifting direction. The lifting groove 1-8 extends towards the platform 8 to form a lifting slot at the bottom 3-1-1 of the housing 1 for the connecting handle 8-14 to enter. This arrangement, with the connecting seat 8-11 located inside the housing 1, allows the lifting drive mechanism to be housed within the housing 1 for better protection. The platform 8-2 and the base 8-12 are located outside the housing 1 for easy placement and removal of the powder container. The connecting handle 8-14 and the lifting groove 1-8 facilitate force transmission between the connecting seat 8-11 and the base 8-12, and ensure smooth lifting.

[0076] In some embodiments, in conjunction with the appendix Figure 12 , 1719. The lower end of the lifting seat 9 has a tube 9-5 into which the guide rod 14 is inserted and slidably fitted. The connecting seat 8-11 has a mating hole 8-13 that is inserted into the tube 9-5. The mating of the tube 9-5 and the mating hole 8-13 improves the connection strength between the connecting seat 8-11 and the lifting seat 9. Through the above-mentioned mating relationship, in addition to the screw connection, the connection between the connecting seat 8-11 and the lifting seat 9 is further increased through the connection between the tube 9-5 and the mating hole 8-13, thereby increasing the contact area between the connecting seat 8-11 and the lifting seat 9, and thus improving the connection strength between the lifting seat 9, the connecting seat 8-11, and the platform 8, and improving the structural stability of the platform 8.

[0077] In some embodiments, in conjunction with the appendix Figure 12 , 14 To better balance the torque, the column 10-1 can have a protrusion 10-5 on the side near the platform 8, and at least one protrusion 10-5 is fixedly connected to the housing 1. This allows the protrusion 10-5 to form a support point on the side of the column 10-1 near the platform 8, so that when the powder receiving container is subjected to force on the platform 8, the connection between the protrusion 10-5 and the housing 1 can improve the structural stability of the powder dispensing device.

[0078] In some embodiments, to facilitate the installation of the protrusion 10-5, at least one protrusion 10-5 may be installed in the following manner. (Referring to the accompanying drawings) Figure 12 , 14 The housing 1 includes a bottom cover 11, on which a mounting post 11-1 is provided. A first mounting hole is formed within the mounting post 11-1. A second mounting hole is provided corresponding to the position of the protrusion 10-5 at the first mounting hole. A screw is screwed into the first and second mounting holes to fix the bottom cover 11 to the gantry frame 10. At least one of the first and second mounting holes is a threaded hole that engages with the screw. The first mounting hole can be a through hole, and the second mounting hole can be a threaded hole for threaded engagement with the screw. The screw can be a screw. The mounting post 11-1 supports the gantry frame 10 to prevent it from tilting towards the platform 8. That is, when the platform 8 is subjected to the pressure of a heavy object, the mounting post 11-1, with its certain height, can support the gantry frame 10 and prevent it from tilting.

[0079] In some embodiments, the powder outlet side 15 forms a support surface inside the housing 1 (not shown in the figure), and the height of some of the protrusions 3-5 corresponds to the height of the support surface, so that the protrusions 10-5 can be supported and fixed on the support surface, thereby improving the structural stability of the gantry frame 10.

[0080] In some embodiments, as shown in the appendix Figure 20-27As shown, the housing 1 can be inverted L-shaped, including a vertical part and a cantilever part. The vertical part is used to place on the table, and the cantilever part is connected to the top of the vertical part. The lower side of the cantilever part is used to arrange the platform 8. The housing openings 1-6 are located on the lower side of the cantilever part. With the above arrangement, the structure can be made simpler and more convenient to use.

[0081] like Figure 20 , Figure 21 As shown, the material-stopping drive mechanism 5 is installed inside the housing 1, i.e., in the inner cavity, and can be a motor. The output end of the material-stopping drive mechanism 5 has a gear 17. The housing surface 1-5, where the housing opening 1-6 is located, has an opening 1-7 for partially exposing the gear 17, facilitating meshing and transmission with the rack 4-1 on the baffle 4. The opening 1-7 can also be referred to as the exposed opening. The material-stopping drive mechanism 5 is mainly a rotary drive device, generally a motor, but it can also be other rotary drive devices, such as a hydraulic motor. The electric drive device and the gear 17 can be directly connected or transmitted through a transmission mechanism, such as the gear 17 group. It should be noted that the gear 17 does not need to be completely exposed in the opening 1-7; it only needs to be able to mesh with the rack 4-1. Generally, only a small portion of the gear 17 needs to be exposed in the opening 1-7; however, the entire gear 17 can also be completely exposed in the opening 1-7. An opening 1-7 is provided on the shell surface 1-5 so that the gear 17 can be exposed on the outside of the shell 1 to mesh with the rack 4-1 on the outside of the shell 1.

[0082] The baffle 4 is detachably disposed on the outside of the housing 1, allowing it to be removed from the outside of the housing 1 to improve ease of removal. The detachable placement of the baffle 4 on the outside of the housing 1 can take at least two forms: one form is where the baffle 4 is directly and detachably connected to the housing 1, such as through a snap-fit ​​structure, magnetic attraction structure 25, or detachable slide rail structure; the other form is where an intermediate structure is provided, which is connected to the housing 1, and the baffle 4 is detachably connected to the intermediate structure. This intermediate structure is the support tray 18 described below, which is detachably connected to the housing 1, and the relationship between the baffle 4 and the housing 1 is constrained by the support tray 18.

[0083] The baffle 4 is fixed with a rack 4-1 that meshes with the gear 17. Through the meshing of the gear 17 and the rack 4-1, when the material blocking drive mechanism 5 drives the gear 17 to rotate, it can drive the baffle 4 to move relative to the housing 1. The movement of the baffle 4 relative to the housing 1 can close the powder outlet 2-2 or open the powder outlet 2-2.

[0084] Specifically, such as Figure 22As shown, the baffle 4 has a feed port 4-2. Driven by the gear 17, the baffle 4 can move to either connect the feed port 4-2 with the powder outlet 2-2 or block the powder outlet 2-2. When the baffle 4 is moved to connect the feed port 4-2 with the powder outlet 2-2, the powder can flow out through the feed port 4-2 to achieve discharge. When the baffle 4 is moved to block the powder outlet 2-2, the powder is blocked by the baffle 4, thus sealing and preserving the powder in the powder hopper 2 to prevent the powder from getting damp or clumping.

[0085] If the baffle 4 is restricted relative to the housing 1, its movement can occur between a first position where the powder outlet 2-2 is connected to the baffle 4 and a second position where the powder outlet 2-2 is not connected to the baffle 4, such as by means of the housing 1 or the support tray 18 described later, restricting the baffle 4 to slide only relative to the housing 1 in the direction of movement (X1, X2). (See attached...) Figure 25 As shown, the device can slide from the second position to the first position along the X1 direction to move to the second state, thereby opening the powder outlet 2-2; and it can slide from the first position to the second position along the X2 direction to move to the first state, thereby closing the powder outlet 2-2. One example is as follows: if gear 17 rotates in the forward direction, it can move baffle 4 to the first position; if gear 17 rotates in the reverse direction, it can move baffle 4 to the second position. When baffle 4 is in the first position, the feed port 4-2 is connected to the powder outlet 2-2. If they are aligned, the powder outlet 2-2 is open. When baffle 4 is in the second position, the feed port 4-2 and the powder outlet 2-2 are offset, and the solid part of baffle 4 blocks the powder outlet 2-2, thus closing the powder outlet 2-2.

[0086] In the aforementioned powder dispensing device, during use, the baffle 4 is installed on the outside of the housing 1, and the rack 4-1 on the baffle 4 meshes with the gear 17. This allows the baffle 4 to move when the output end of the material-blocking drive mechanism 5 rotates, thereby opening and closing the powder outlet 2-2. When powder dispensing is needed, the powder outlet 2-2 is opened; when not dispensing, it is closed. This effectively prevents external air from prolonged contact with the powder at the powder outlet 2-2, thus preventing powder clumping and improving the overall performance. After a period of use, if the powder accumulated on the baffle 4 needs further cleaning, the baffle 4 can be directly removed from the outside of the housing 1 for cleaning, such as washing and / or sweeping. This makes disassembly and cleaning of the baffle 4 convenient, further improving the performance. In summary, this powder dispensing device effectively solves the problem of powder dispensing devices easily causing milk powder to become damp and clump.

[0087] In some embodiments, to facilitate the installation of the baffle 4 and to allow the baffle 4 to move relative to the housing 1, an intermediate structure may be further provided. Specifically, the intermediate structure may be a support tray 18, which is detachably installed on the outside of the housing 1. The support tray 18 has a disc surface opposite to the powder outlet 2-2, and the disc surface and the housing surface 1-5 define a space for accommodating the baffle 4. The baffle 4 moves on the support tray 18 under the drive of the material blocking drive mechanism 5.

[0088] In some embodiments, the support tray 18 can further restrict the range of motion of the baffle 4 while supporting it, as described above, to limit movement between the first and second positions. The structure and shape of the support tray 18 are not limited; they can be configured as needed to achieve the aforementioned functions. (See attached...) Figure 23 In this embodiment, a portion of the outer periphery of the support tray 18 conforms to the corresponding outer periphery of the housing 1. The surface of the support tray 18 opposite to the baffle 4 is provided with a receiving groove 18-3, as shown in the attached figure. Figure 25 As shown, the baffle 4 is placed in the receiving groove 18-3, which restricts the movement of the baffle 4, so as to guide the movement of the baffle 4 along the X1 and X2 directions and restrict the movement of the baffle 4 in the front-back direction perpendicular to the X1 and X2 directions.

[0089] Preferably, the support tray 18 has mounting limiting surfaces 18-14, as shown in the attached diagram. Figure 23 As shown, protrusions 10-5 can be formed on both sides respectively. The side of the protrusion 10-5 (the front side in the pushing direction) forms the above-mentioned mounting limiting surface 18-14. When the support tray 18 is pushed into place, it can abut against the housing 1 through the mounting limiting surface 18-14 to prevent the support tray 18 from moving further forward.

[0090] In some embodiments, as shown in the appendix Figure 23 , 24As shown, to facilitate powder conveying, the support tray 18 can also have a powder conveying channel 18-10, wherein the powder conveying channel 18-10 is positioned corresponding to the powder outlet 2-2, such as being aligned. Specifically, the central axes of the powder outlet 2-2 and the powder conveying channel 18-10 can be coincident, and preferably the cross-section of the powder conveying channel 18-10 is slightly larger than the cross-section of the powder outlet 2-2, so as to improve material discharge. Specifically, when the material conveying port 4-2 coincides with the powder outlet 2-2, their central axes also coincide. Furthermore, the powder outlet 2-2, material conveying port 4-2, and powder conveying channel 18-10 can be arranged sequentially, with the cross-sectional area gradually increasing. As shown in the attached diagram, the cross-sections are preferably circular, but they can also be square. The cross-sectional shapes of the powder outlet 2-2, the material passage 4-2, and the powder passage 18-10 can be the same or different. For example, the powder outlet 2-2 can be circular, while the cross-sections of the powder passage and the powder passage 18-10 can be square, preferably with a side length greater than the diameter of the powder outlet 2-2. The powder passage 18-10 can extend from the surface of the support tray 18 towards the powder outlet 2-2.

[0091] As attached Figure 24 As shown, at least one flat surface is formed on the lower side of the support tray 18, i.e., the side facing the platform 8, to serve as a contact surface 18-13 for contacting the bottle neck. The lower end of the powder passage 18-10 is located at the contact surface 18-13, and an arc-shaped protrusion 18-12 is formed on at least one side of the powder passage 18-10 to enlarge the contact surface 18-13, increase the contact area between the contact surface 18-13 and the bottle neck, thereby adapting to bottles of different diameters and preventing powder from drifting out of the bottle neck due to partial gaps in the bottle neck covered by the contact surface 18-13.

[0092] In some embodiments, the support tray 18 and the housing 1 are detachably connected, such as by snap-fit ​​connection, magnetic connection, etc. Detachable connection generally refers to quick-release connection, such as snap-fit ​​connection by buckle connection or other snap-fit ​​structure connection.

[0093] For ease of operation, a push-pull connection can be formed between the support tray 18 and the housing 1. This push-pull connection improves the load-bearing capacity between the support tray 18 and the housing 1, thereby enhancing the support effect on the baffle 4. In the push-pull direction, a flexible limiting structure can be used to further limit relative movement in the push-pull direction. Under a large external force, the flexible limiting structure can be released, allowing the support tray 18 to be detached.

[0094] The support tray 18 forms a push-pull connection with the housing 1 along a preset direction (front-to-back direction), as shown in the attached diagram. Figure 25As shown, in the forward direction, the support tray 18 can be pushed into the corresponding position of the housing 1; while in the backward direction, the support tray 18 can be pulled out from the housing 1 to separate from the housing 1. The preset direction is perpendicular to the moving direction of the baffle 4 and parallel to the baffle 4. The preset direction is perpendicular to the extending direction of the rack 4-1, and the extending direction of the rack 4-1 is consistent with the moving direction of the baffle 4. A push-pull connection is achieved by moving perpendicular to the extending direction of the rack 4-1 and along the axial direction of the gear 17, so that when the support tray 18 is assembled, the rack 4-1 and the gear 17 move relative to each other along the axial direction of the gear 17 to complete the meshing. Both the gear 17 and the rack 4-1 can be of a spur gear structure.

[0095] In some embodiments, to facilitate push-pull connection, the housing 1 may have support shoulders 1-3 on both sides of the support tray 18 for supporting the support tray 18. Figure 20 (As shown in the diagram). Simultaneously, the shell wall with supporting shoulders 1-3 can further limit the support tray 18 in the moving direction (X1, X2 directions) of the baffle 4, such as limiting the support tray 18 in the moving direction of the baffle 4. Figure 23 As shown, the support tray 18 can have support ear plates 18-7 on both sides that overlap the upper side of the support shoulder 1-3 to support the support tray 18. One end of the support ear plate 18-7 has an upwardly inclined guide plate 18-8, so that when the support tray 18 is inserted, the lower side of the guide plate 18-8 can abut against the support shoulder 1-3 to guide the support ear plate 18-7 to move to the upper side of the support shoulder 1-3.

[0096] In some embodiments, each side of the support ear plate 18-7 may include two parallel supports arranged vertically, with the two support ear plates 18-7 spaced apart to form a channel for the support shoulder 1-3 to be inserted, which improves the accuracy of the positioning of the support tray 18 and the support shoulder 1-3 and improves the installation efficiency of the support tray 18.

[0097] Furthermore, for ease of fixation, as shown in the attached document. Figure 23 As shown, one end of the support tray 18 (the front end of the support tray 18 in the direction of being pushed into the housing 1) can be plugged into the housing 1, and the other end of the support tray 18 (the rear end of the support tray 18 in the direction of being pushed into the housing 1) can be snapped into the housing 1. Specifically, it can be snapped into the housing 1 through the slot 1-2 and the protrusion 18-5 to improve the stability of the support tray 18 structure and make the connection convenient.

[0098] In some embodiments, an elastic limiting device 19 may be further provided as the aforementioned elastic limiting structure. This elastic limiting device 19 prevents the support tray 18 from moving outward after it has been inserted into place.

[0099] Specifically, the elastic limiting device 198 may include a ball and an elastic element (not shown) for elastically supporting the ball. The ball can be compressed by the elastic element and retracted into a ball mounting groove on the surface of the housing 1, or the ball can protrude from the ball mounting groove under the elastic restoring force of the elastic element. After the support tray 18 is installed in place, the ball can enter the limiting position under the action of the elastic element, that is, it is located in the receiving groove 18-3 and abuts against the limiting groove wall 18-11 of the receiving groove 18-3 to prevent the support tray 18 from leaving the installation position. When the external force on the support tray 18 is relatively large, it is sufficient for the limiting groove wall 18-11 to push the ball to overcome the elastic deformation force of the elastic element, so that the ball leaves the limiting position.

[0100] Furthermore, for ease of operation, the support tray 18 can be provided with a hand hole 18-6 to facilitate the application of force to the support tray 18.

[0101] The support tray 18 includes a receiving groove 18-3 for accommodating the baffle 4, wherein the groove wall of the receiving groove 18-3 can serve as the aforementioned limiting groove wall 18-11. For example, when the support tray 18 is in the installation position, the aforementioned ball can be located in the receiving groove 18-3 to abut against the limiting groove wall 18-11 of the receiving groove 18-3.

[0102] In some embodiments, when the support tray 18 is provided with a receiving groove 18-3, at least one of the groove walls of the receiving groove 18-3 can protrude outward to form an expansion groove 18-4 for dust accumulation. Specifically, both sides of the receiving groove 18-3 along the moving direction of the baffle 4 can have outwardly expanding expansion grooves 18-4, and preferably the expansion grooves 18-4 are arc-shaped grooves to improve structural strength and reduce the number of corners, thus facilitating the cleaning of accumulated dust.

[0103] In some embodiments, the powder outlet 2-2 can be located at the bottom 3-1-1 of the powder hopper 2; the powder hopper 2 is provided with a powder outlet screw 3 for pushing the powder out, and the powder outlet screw 3 extends to the powder outlet 2-2. The powder is pushed towards the powder outlet 2-2 by the rotation of the powder outlet screw 3. At this time, the powder outlet screw 3 is equivalent to a screw conveyor.

[0104] The powder outlet 2-2 is generally positioned opposite the platform 8, which is used to hold containers such as baby bottles. For ease of arrangement, a suspended shell plate 1-4 can be provided, parallel to the platform 8 and positioned directly above it. The lower side of the suspended shell plate 1-4 is the shell surface 1-5, and the support tray 18 is located directly below the suspended shell plate 1-4. The drive source is installed on the upper side of the suspended shell plate 1-4.

[0105] In some examples, such as the attached Figure 1As shown, the powder hopper 2 is preferably detachably mounted on the outer cylinder 21, meaning it can be removed from the outer cylinder 21. Specifically, the powder hopper 2 can be placed inside the outer cylinder 21 from the upper opening and fixed in place. When the hopper cover 6 is opened, it can be removed from the upper opening of the outer cylinder 21 for easy removal and cleaning. The outer cylinder 21 facilitates the installation of the powder hopper 2, restricting its range of motion while making it easy to remove and place. The hopper cover 6 covers the inlet 2-1 of the powder hopper 2 and is mounted on the housing 1. It can be rotated as shown in the attached figure to open by flipping, or it can be snapped on by a latch, clip, or other means, or it can be directly sealed to the inlet 2-1 for removal from the housing 1. To prevent powder leakage and ensure the cleanliness of the powder hopper 2, a sealing ring can be provided between the outer wall of the hopper cover 6 and the inner wall of the powder hopper 2. Specifically, the sealing ring can be fixed on the outer wall of the hopper cover 6, and its outer side abuts against the inner wall of the powder hopper 2, so as to always seal the gap between the hopper cover 6 and the inner wall of the powder hopper 2 during relative movement.

[0106] In some embodiments, the powder discharge screw 3 can be detachably mounted on the hopper cover 6, such as being detachably connected to a screw drive mechanism on the hopper cover 6. To facilitate the detachable connection between the hopper cover 6 and the powder discharge screw 3, a first coupler can be provided on the inner side of the hopper cover 6, and a second coupler can be provided on the top of the powder discharge screw 3. The first coupler and the second coupler are coupled in an anti-rotational manner, thereby preventing the hopper cover 6 and the powder discharge screw 3 from rotating relative to each other, and indirectly preventing the powder discharge screw 3 from rotating relative to the housing 1, thus ensuring normal powder discharge. The second coupler can be a straight connecting handle, and the first coupler can be a perforated groove, such as a perforated groove with six mating grooves. The two ends of the straight connecting handle are respectively located in two opposite mating grooves. In this case, the second coupler and the first coupler have at least three mating positions at different angles, which greatly improves the success rate of the first coupler and the second coupler coupling at one time, so as to facilitate closing the hopper cover 6. To improve the connection stability of the first coupler on the compartment cover 6 and prevent them from easily detaching, a magnetic attraction structure can be provided at the installation position of the first coupler to magnetically fix it. This improves the ease of installation and stability during use, preventing the first coupler from falling off the compartment cover 6. Specifically, to facilitate the installation of the magnetic attraction structure 25, an installation groove can be provided on the compartment cover 6, into which the magnetic attraction structure is inserted and fixed.

[0107] In some embodiments, when a cover 6 is provided for sealing the inlet 2-1 of the powder hopper 2, a one-way valve can be provided on the cover 6 to control the unidirectional flow of gas from the outside of the cover 6 to the inside of the powder hopper 2. The one-way valve prevents the gas inside the powder hopper 2 from randomly exchanging gas with the outside air, thus preventing the outside air from randomly entering the powder hopper 2 and preventing the milk powder from getting damp. When the internal air pressure is low, air can be added to avoid problems such as poor powder dispensing and the inability to open the cover 6 due to low internal air pressure. It should be noted that the orifice of the one-way valve should be as small as possible to prevent the milk powder from getting damp. In some embodiments, a small through hole can also be provided in the cover 6 to ensure that the powder hopper 2 is always connected to the outside atmosphere, preventing the generation of negative pressure. In some embodiments, a solenoid valve can also be provided, and the connection or disconnection between the powder hopper 2 and the atmosphere can be achieved by controlling the opening and closing of the solenoid valve.

[0108] In some embodiments, as shown in the accompanying drawings, a powder discharge drive mechanism can be provided on the silo cover 6 to drive the powder discharge screw 3 to rotate. Specifically, the discharge drive mechanism can be a structure where a motor drives a driving gear and a driven gear to rotate, thereby rotating the powder discharge screw. Installed on the silo cover 6, this method is simpler and more convenient than installing it in other locations. The powder discharge screw 3 is detachably connected to the silo cover 6 for easy disassembly and maintenance. To facilitate detachable connection, the drive end of the discharge drive mechanism and the powder discharge drive mechanism can be coupled via a first coupler and a second coupler (described later) to achieve transmission.

This automatic brewing machine includes any one of the powder dispensing devices described in the above embodiments, and further includes a liquid supply device. The liquid supply device and the powder dispensing device are used to supply liquid and powder to the container, respectively. Since this automatic brewing machine uses the powder dispensing device described in the above embodiments, the beneficial effects of this automatic brewing machine can be found in the above embodiments. Examples of automatic brewing machines include automatic coffee makers, automatic milk powder makers, and automatic soy milk makers.

[0110] In some embodiments, the liquid supply interface 1-1 of the liquid supply device can be fixedly installed on the housing 1 of the powder dispensing device. The support tray 18 of the powder dispensing device is provided with a liquid passage 18-1. One end of the liquid passage 18-1 is provided with a liquid inlet interface 18-2 and the other end is provided with a liquid outlet 18-9. The liquid inlet interface 18-2 is connected to the liquid supply interface 1-1 of the liquid supply device.
