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] When formula feeding infants, the amount of formula per feeding often needs to be determined based on the infant's age; the amount of formula varies with age. To facilitate precise dispensing, a powder dispensing device is often used to dispense the formula, improving the accuracy of dispensing.

[0003] However, the position of the powder dispensing nozzle in existing powder dispensing devices is fixed, while the available baby bottles vary greatly, especially in height. If the distance between the powder receiving position and the powder dispensing nozzle cannot be matched to different bottle heights, the powder tends to spill outside the bottle when dispensing, resulting in waste and affecting the accuracy of the amount of powder entering the bottle container, seriously impacting the user experience.

[0004] In conclusion, how to effectively solve the problem of poor powder output from powder discharge devices is an urgent issue that needs to be addressed by those skilled in the art. Utility Model Content

[0005] 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. The second objective of this utility model is to provide an automatic brewing machine including the above-mentioned powder dispensing device.

[0010] A lifting drive mechanism is connected to the platform to drive the platform closer to or further away from the powder outlet, and the lifting drive mechanism drives the platform to approach the powder outlet in such a way that the container opening of the powder receiving container placed on the platform abuts against the powder outlet side.

[0011] In the aforementioned powder dispensing device, during use, the powder receiving container can be placed on the platform, with its opening roughly aligned with the powder dispensing outlet. Then, the lifting drive mechanism drives the platform upwards towards the powder dispensing outlet until the container opening touches the dispensing side. At this point, the rim of the container opening surrounds the dispensing outlet, and the powder in the dispensing chamber flows out from the outlet. The flowing powder completely falls into the container opening to enter the receiving container. Once powder collection is complete, the dispensing outlet stops dispensing powder, and the lifting drive mechanism lowers the platform back to its original position, allowing the receiving container to be removed. In this powder dispensing device, the arrangement of the dispensing chamber and the lifting drive mechanism ensures that the container opening touches the dispensing side during powder dispensing, effectively preventing lateral powder overflow and improving the powder receiving effect. In summary, this powder dispensing device effectively solves the problem of poor powder dispensing efficiency in traditional powder dispensing devices.

[0051] This utility model discloses a powder dispensing device that can effectively solve the problem of poor powder dispensing effect.

[0052] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0054] In some embodiments, a powder dispensing device is provided for dispensing powder, such as milk powder, coffee powder, soy milk powder, etc. Specifically, as shown in the attached document... Figure 1 As shown, the powder dispensing device can include at least a powder dispensing chamber 9, a platform 1, and a lifting drive mechanism (such as an attached...). Figure 3 (Including the central motor 5, screw 6, and lifting seat 2, etc.).

[0055] The powder dispensing compartment 9 has a powder dispensing port 9-1 on its powder dispensing side 10, allowing milk powder in the compartment 9 to be discharged through the powder dispensing port 9-1 on the powder dispensing side 10. (See attached image) Figure 1 As shown, the powder outlet side 10 of the powder outlet 9 is the lower side of the powder outlet 9, and the powder outlet 9-1 is set downward so that it can flow downward under the action of gravity.

[0056] The stage 1 is used to place the powder receiving container (not shown), which is positioned opposite the powder outlet 9-1, so that when the powder receiving container is placed on the stage 1, the container opening of the powder receiving container can face the powder outlet 9-1 to receive the powder flowing out of the powder outlet 9-1.

[0057] The lifting drive mechanism is connected to the platform 1 to drive the platform 1 closer to or further away from the powder outlet 9-1. The lifting drive mechanism drives the platform 1 to approach the powder outlet 9-1 such that the opening of the powder receiving container placed on the platform 1 abuts against the powder outlet side. By having the opening of the powder receiving container abut against the powder outlet side 10, the rim of the container opening forms a circumferential surround around the powder outlet 9-1, ensuring that all the powder flowing out of the powder outlet 9-1 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 9-1.

[0058] In some embodiments, as shown in the appendix Figure 1As shown, in the powder dispensing device described above, during use, a powder receiving container (not shown) can be placed on the platform 1, with the container opening basically aligned with the powder outlet 9-1 (i.e., the powder outlet 9-1 is inside the container opening). Then, the lifting drive mechanism drives the platform 1 to move upward towards the powder outlet 9-1 until the container opening abuts against the powder outlet side 10. At this point, the rim of the container opening surrounds the powder outlet, and the powder in the powder dispensing chamber 9 is driven to flow out from the powder outlet 9-1. The outflowing powder completely enters the receiving container through the container opening. Powder dispensing continues until the powder dispensing is complete, at which point the powder outlet stops dispensing. Then, the lifting drive mechanism drives the platform 1 to descend and reset, and the receiving container can be removed. In the powder dispensing device described above, the arrangement of the powder dispensing chamber 9 and the lifting drive mechanism ensures that when dispensing powder, the container opening abuts against the powder outlet side 10 to surround the powder outlet 9-1, effectively preventing lateral flow and overflow of powder and improving the powder dispensing effect. In summary, this powder dispensing device can effectively solve the problem of poor powder dispensing performance in powder dispensing devices.

[0059] In some embodiments, as shown in the appendix Figure 2 , 3 As shown, for ease of driving, the lifting drive mechanism can include a motor 5, a screw 6, and a lifting seat 2. One end of the screw 6 is fixed to the motor 5, and the extension direction of the screw 6 is the same as the lifting direction of the platform 1. The lifting seat 2 is located on one side of the platform 1, which avoids interference with the lifting and lowering of the platform 1, making the structure simpler. The lifting seat 2 includes a connecting part 2-1, which has a threaded groove that mates with the screw 6. That is, a screw-nut transmission mechanism is formed between the motor 5 and the lifting seat 2 through the screw 6 and the threaded groove in the connecting part 2-1, so that when the motor 5 drives the screw 6 to rotate, the threaded engagement between the connecting part 2-1 of the lifting seat 2 and the screw causes the lifting seat 2 to move along the extension direction (i.e., the axial direction) of the screw 6. Since the extension direction of the screw 6 is the same as the lifting direction of the platform 1, the rotation of the motor 5 can drive the lifting seat to move along the lifting direction. It should be noted that a metal nut 2-6 with a threaded groove can be integrated on the lifting seat 2.

[0060] Specifically, when motor 5 rotates forward, screw 6 rotates synchronously in the same direction, causing lifting seat 2 to rise. When motor 5 rotates in reverse, screw 6 rotates synchronously in the opposite direction, causing lifting seat 2 to fall. In use, initially, the powder receiving container is placed on the platform 1. Motor 5 starts rotating forward, lifting seat 2 rises, and platform 1 rises synchronously until the opening of the powder receiving container on platform 1 touches the powder dispensing side 10. Then motor 5 stops rotating. Powder is dispensed from powder dispensing chamber 9. After powder dispensing is complete (or after the liquid supply device completes its supply later), motor 5 reverses, lifting seat 2 falls, and platform 1 falls synchronously until it returns to its initial position, at which point motor 5 stops rotating.

[0061] In the above configuration, transmission is achieved through a lead screw and nut transmission mechanism, enabling the motor 5 to raise and lower the lifting seat 2. The lead screw and nut transmission mechanism is a compact transmission component, and the motor 5 is a relatively convenient drive source, resulting in a compact overall structure and good driving effect. Furthermore, the current of the motor 5 can be detected to ensure it does not exceed a specified value. If it does, it indicates that the container opening is in contact with the powder outlet side 10, affecting further rotation of the motor 5, and the motor 5 will automatically stop. The current of the motor 5 can be detected through its own structure or through an external current detection structure; this embodiment does not impose any limitations. Furthermore, the powder dispensing device also includes a controller (not shown in the figure) to control the start and / or stop of the motor 5 and other electrical components, improving the automation level of the powder dispensing device.

[0062] 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.

[0063] In some embodiments, as shown in the appendix Figure 2 , 3 As shown in Figure 6, for ease of arrangement and to make the structure simpler and more convenient, the connecting part 2-1 can be located on the side of the lifting seat 2 away from the platform 1. This allows the connecting part 2-1 and the platform 1 to be positioned on opposite sides, so that the force is evenly distributed on both sides.

[0064] In some examples, the lifting seat 2 may also include a seat body 2-2, with the connecting part 2-1 located on the side of the seat body 2-2 away from the platform 1.

[0065] In some examples, the lifting seat 2 may also include a seat body 2-2, with a connecting portion 2-1 located on the side of the seat body 2-2 away from the platform 1. The connecting portion 2-1 protrudes from the surface of the seat body 2-2 to form a protruding structure that extends in a direction away from the platform 1.

[0066] In the above configuration, the connecting part 2-1 is located on the side of the seat 2-2 away from the platform 1, so that the connecting part 2-1 and the platform 1 are respectively arranged on both sides of the seat 2-2, so that they are respectively subjected to external forces on both sides of the seat 2-2. This allows for lifting and lowering movement while achieving left-right balance. Compared with the platform 1 and the connecting part 2-1 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.

[0067] In some embodiments, as shown in the appendix Figure 4 , 5As shown, a gantry frame 3 can be further provided to facilitate the installation of structures such as the lifting platform 2. Specifically, the gantry frame 3 includes two columns 3-1 and a first crossbeam 3-4 fixed to the top of the two columns 3-1, so that the two columns 3-1 and the first crossbeam 3-4 are combined to form a gantry structure.

[0068] As attached Figure 4 As shown, two columns 3-1 are arranged side by side. The left end of the first crossbeam 3-4 is connected to the left column 3-1, and the right end of the first crossbeam 3-4 is connected to the right column 3-1. The first crossbeam 3-4 and the column 3-1 are integrally formed and connected. Of course, they can also be connected by screws or other methods.

[0069] Combined with appendix Figure 2 , Figure 3 As shown, the first crossbeam 3-4 has a mounting structure for the end of the screw 6 away from the motor 5 to be rotatably mounted. A specific mounting structure can be described as follows: The first crossbeam 3-4 has a cylindrical hole for the end of the screw 6 to be inserted, allowing the screw 6 to rotate. At this time, the end of the screw 6 forms a shoulder. Two screw washers 11 are fixed to the first crossbeam 3-4 and pressed against both sides of the shoulder for fixation. The cylindrical hole and the two screw washers 11 together form the aforementioned mounting structure. Each screw washer 11 includes a washer and a screw. The screw passes through the central hole of the washer to fix the washer to the first crossbeam 3-4.

[0070] Combined with appendix Figure 2 As shown, in the left-right direction, the lifting seat 2 is located between the two uprights 3-1 of the gantry frame 3. The seat body 2-2 is located on the side of the first crossbeam 3-4 facing the platform 1, where the side of the first crossbeam 3-4 facing the platform 1 refers to the side facing the user. (See attached image) Figure 2 As shown, the seat 2-2 is located on the rear side of the platform 1 and on the front side of the first crossbeam 3-4. By setting the lifting seat 2 between the two columns 3-1 and placing the seat 2-2 on the side of the first crossbeam 3-4 facing the platform 1, the lifting seat 2 is positioned entirely inside the gantry 3, resulting in centered force distribution and more stable overall operation.

[0071] In some embodiments, as shown in the appendix Figure 3 , 5 As shown, the gantry frame 3 includes a second crossbeam 3-2 located between two columns 3-1, wherein the connecting part 2-1 is located directly above the second crossbeam 3-2, that is, between the first crossbeam 3-4 and the second crossbeam 3-2.

[0072] As attached Figure 4As shown, two columns 3-1 are arranged side by side. The left end of the second crossbeam 3-2 is connected to the left column 3-1, and the right end of the second crossbeam 3-2 is connected to the right column 3-1. The second crossbeam 3-2 and the column 3-1 are integrally formed and connected. Of course, they can also be connected by screws or other methods.

[0073] The second crossbeam 3-2 is provided with a through groove 3-21 for the screw 6 to pass through. The through groove 3-21 communicates with the threaded groove on the lifting seat 2, i.e., they are coaxially arranged, so that the upper end of the screw 6 is fixed in the mounting structure of the first crossbeam 3-4, the lower end can pass through the through groove 3-21 of the second crossbeam 3-2, and the middle part passes through the lifting seat 2, with its external thread engaging with the threaded groove on the lifting seat 2. (See attached image) Figure 2 As shown, the threaded groove is integrated on the metal nut 2-6.

[0074] The motor 5 is located directly below the second crossbeam 3-2, utilizing the lower space of the second crossbeam 3-2 to accommodate the motor 5. The screw 6 passes through the through slot of the second crossbeam 3-2 to connect with the motor 5 located below the second crossbeam 3-2.

[0075] In the above embodiment, by setting the second crossbeam 3-2, a mounting space for the motor 5 is formed on the lower side of the second crossbeam 3-2, allowing the connecting part 2-1 to be staggered vertically on the upper side of the second crossbeam 3-2. This facilitates the accommodation and installation of the motor 5, resulting in a more compact overall structure. Furthermore, the lower placement of the motor 5 improves the stability of the overall structure and helps maintain the balance of forces on the gantry frame when the lifting seat 2 drives the platform 1 to rise. Additionally, without affecting the lifting mechanism, the lifting seat 2 can be positioned parallel to the motor 5 at approximately the same height (instead of being positioned above the motor 5). This reduces both the minimum and maximum lifting height of the platform 1, lowering the overall height of the powder dispensing device and facilitating its miniaturization, thus saving space.

[0076] Of course, in some examples, the motor 5 can also be installed on the first crossbeam 3-4 (not shown in the figure). In this case, too much space is needed on the upper side of the first crossbeam 3-4 to install the motor 5, which will lead to inconvenient installation and poor stability.

[0077] In some embodiments, such as Figure 2 , 3 As shown in Figure 6, the lifting drive mechanism also includes a guide rod 8. The lifting seat 2 has a guide groove 2-3 through which the guide rod 8 passes, so as to guide the lifting seat 2 through the guide rod 8 to ensure smooth lifting of the lifting seat 2. (See attached figure) Figure 2 , 3As shown, the guide rod 8 is arranged parallel to the screw 6 to guide the lifting seat 2 in the lifting direction. The guide rod 8 can be a cylindrical rod, but is not limited to any particular type. Specifically, one or more guide rods 8 can be provided; this is not restricted.

[0078] In some examples, it can also be as shown in the appendix. Figure 2 , 3 As shown, each screw 6 is provided with two guide rods 8, which are respectively positioned on the left and right sides of the screw 6, as shown in the attached diagram. Figure 6 As shown, guide rods 8 can be provided on both sides of the connecting part 2-1 in the left and right directions. By guiding the screw 6 on both sides, the force on both sides can be evenly distributed, thus making the lifting and lowering more stable.

[0079] In some embodiments, as shown in the appendix Figure 4 As shown, the gantry 3 also includes a bottom beam 3-3, which connects to the bottom of the two uprights 3-1. The bottom beam 3-3 can extend to form an integral structure with the second crossbeam 3-2, thereby increasing the overall strength of the gantry 3. In particular, the bottom beam 3-3 further supports the second crossbeam 3-2 to ensure its support strength and better support the motor 5. Of course, in some examples, the bottom beam 3-3 may not extend to the second crossbeam 3-2.

[0080] As attached Figure 4 As shown, two columns 3-1 are arranged side by side, the left end of the bottom beam 3-3 is connected to the left column 3-1, and the right end of the bottom beam 3-3 is connected to the right column 3-1. The bottom beam 3-3 and the column 3-1 are integrally formed and connected. Of course, they can also be connected by screws or other methods.

[0081] As attached Figure 2 , 4 As shown, the two ends of the guide rod 8 are fixed to the first crossbeam 3-4 and the bottom beam 3-3 respectively, so as to fix the guide rod 8 through the first crossbeam 3-4 and the bottom beam 3-3. The guide rod 8 is generally a cylindrical rod. The bottom beam 3-3 has a cylindrical hole that mates with the guide rod 8 for insertion. The first crossbeam 3-4 has a cylindrical hole that mates with the guide rod 8 for insertion. The upper side of the first crossbeam 3-4 has a screw washer 11 to press and position the upper end of the guide rod 8.

[0082] In some embodiments, as shown in the appendix Figure 8 The platform 1 can include a bracket 1-1 and a platform 1-2, wherein the platform 1-2 is disposed on the bracket 1-1, and the upper side of the platform 1-2 forms a loading surface for placing powder receiving containers. The bracket 1-1 is used to support the platform 1-2 and is installed on the lifting seat 2.

[0083] In some embodiments, as shown in the appendix Figure 9As shown, the bracket 1-1 includes a connecting seat 1-11, a base 1-12, and a connecting handle 1-14.

[0084] The connecting seat 1-11 is fixed to the side of the lifting seat 2 facing the platform 1. For example, the connecting seat 1-11 is provided with screw holes so that it can be fixed to the lifting seat 2 by screws.

[0085] The base support 1-12 supports and limits the position of the tabletop 1-2. The base support 1-12 is annular, with a support surface on its upper side to support the lower side of the tabletop 1-2. 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 tabletop 1-2. This protrusion limits the position of the tabletop 1-2, preventing lateral movement and stabilizing it on the base support 1-12. It is also easy to remove for cleaning the tabletop 1-2.

[0086] The connecting handle 1-14 connects the connecting seat 1-11 and the base 1-12 to transmit the supporting force.

[0087] The above-mentioned design not only facilitates the placement and removal of the table 1-2, making it easier to clean, but also facilitates the connection between the bracket 1-1 and the lifting seat 2 via the connecting seat 1-11.

[0088] In some embodiments, in conjunction with the appendix Figure 8 , 9 and appendix Figure 1 As shown, the device includes a housing 7, which covers the outside of the lifting drive mechanism. The powder outlet 9 is at least partially installed inside the housing 7. The housing 7 has an opening corresponding to the position of the powder outlet 9-1. The platform 1-2 and the base 1-12 are located outside the housing 7, and the connecting seat 1-11 is located inside the housing 7.

[0089] The housing 7 has a lifting groove 7-1 extending in the lifting direction, the lifting groove 7-1 extending toward the platform 1 to form a lifting groove opening at the bottom of the housing 7 for the connecting handle 1-14 to enter.

[0090] With the above arrangement, the connecting seat 1-11 is located inside the housing 7, so that the lifting drive mechanism is housed inside the housing 7 for better protection. The platform 1-2 and the base 1-12 are located on the outside of the housing 7 for easy placement and removal of the powder receiving container. The connecting handle 1-14 and the lifting groove 7-1 facilitate the transmission of force between the connecting seat 1-11 and the base 1-12 and ensure smooth lifting.

[0091] In some embodiments, in conjunction with the appendix Figure 2 , 79. The lower end of the lifting seat 2 has a tube 2-5 for the guide rod 8 to be inserted and slidably fitted. The connecting seat 1-11 has a mating hole 1-13 that is inserted into the tube 2-5. The mating of the tube 2-5 and the mating hole 1-13 improves the connection strength between the connecting seat 1-11 and the lifting seat 2. Through the above-mentioned mating relationship, in addition to the screw connection, the connection between the connecting seat 1-11 and the lifting seat 2 is further increased through the connection between the tube 2-5 and the mating hole 1-13, thereby increasing the contact area between the connecting seat 1-11 and the lifting seat 2, and thus improving the connection strength between the lifting seat 2, the connecting seat 1-11 and the platform 1, and improving the structural stability of the platform 1.

[0092] In some embodiments, in conjunction with the appendix Figure 2 , 4 To better balance the torque, the column 3-1 can have a protrusion 3-5 on the side near the platform 1, and at least one protrusion 3-5 is fixedly connected to the housing 7. This allows the side of the column 3-1 near the platform 1 to form a support point through the protrusion 3-5. When the powder receiving container is under stress on the platform 1, the connection between the protrusion 3-5 and the housing 7 can improve the structural stability of the powder dispensing device.

[0093] In some embodiments, to facilitate the installation of the protrusions 3-5, at least one protrusion 3-5 may be installed in the following manner. (Referring to the accompanying drawings) Figure 2 , 4 The housing 7 includes a bottom cover 4, on which a mounting post 4-1 is provided. A first mounting hole is formed in the mounting post 4-1. A second mounting hole is provided corresponding to the position of the protrusion 3-5 at the first mounting hole. A screw connector is screwed into the first mounting hole and the second mounting hole to fix the bottom cover 4 to the gantry frame 3. At least one of the first and second mounting holes is a threaded hole that engages with the screw connector. The first mounting hole can be a through hole, and the second mounting hole can be a threaded hole to engage with the screw connector, such as a screw.

[0094] The gantry 3 is supported by the mounting column 4-1 to prevent it from tilting towards the platform 1. That is, when the platform 1 is subjected to the pressure of a heavy object, the mounting column 4-1, with its certain height, can support the gantry 3 and prevent it from tilting.

[0095] In some embodiments, the powder outlet side 10 forms a support surface inside the housing 7 (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 3-5 can be supported and fixed on the support surface, thereby improving the structural stability of the gantry 3.
