Description

Powder dispensing device and automatic brewing machine 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 typically include a formula storage compartment, a feeding screw, and a drive mechanism. The feeding screw dispenses a measured amount of formula, and the drive mechanism rotates the screw to output the formula from the outlet of the storage compartment. Because the formula at the outlet is constantly exposed to outside air, it is prone to becoming damp, clumping, and clogging the outlet. This can potentially enter the bottle during the next formula preparation, affecting food quality and safety.

[0003] In conclusion, how to effectively solve the problem of milk powder easily becoming damp and clumping due to powder dispensing devices is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

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.

[0039] In some embodiments, a powder discharging device is provided. Specifically, the powder discharging device mainly includes a housing 1, a powder hopper 7, a power source 2, and a baffle 4.

[0040] The shell 1 refers primarily to the outer shell, as opposed to the inner shell. One side of the outer shell faces outwards, and the other side faces the inner cavity. Generally, some structures need to be housed within the inner cavity, and these structures are typically not visible or accessible from the outside. Generally, the power source 2 is located within the inner cavity of the shell 1, while the powder hopper 7 can be located either within or outside the inner cavity of the shell 1. As shown in Figure 8, the powder hopper 7 partially extends into the inner cavity of the shell 1.

[0041] The powder hopper 7 is installed on the housing 1, and the specific installation method and location are not limited. As shown in Figure 1, the powder hopper 7 has a discharge port 7-1, through which the powder in the powder hopper 7 can flow out. The powder hopper 7 can be cylindrical or funnel-shaped, and the specific structure is not limited. Generally, the bottom of the powder hopper 7 is provided with a discharge port 7-1 for convenient discharge. To further facilitate discharge, a discharge device, such as a powder discharge screw 9 (shown in Figure 8), can be installed inside the powder hopper 7.

[0042] The housing 1 has openings 1-6, and a discharge port 7-1 can be located inside the housing 1 and opposite to the openings 1-6 to achieve communication, so that the material discharged from the discharge port 7-1 can flow out through the openings 1-6. In a specific example, the housing 1 can be inverted L-shaped, including a vertical section and a cantilever section. The vertical section is used to place on a tabletop, and the cantilever section is connected to the top of the vertical section. The lower side of the cantilever section is used to arrange a support platform 6, and the housing openings 1-6 are located on the lower side of the cantilever section. This arrangement simplifies the structure and makes it more convenient to use.

[0043] As shown in Figures 1 and 2, the power source 2 is installed inside the housing 1, specifically within the inner cavity. The output end of the power source 2 has a gear 3. The housing surface 1-5, where the housing opening 1-6 is located, has an opening 1-7 that allows part of the gear 3 to protrude, facilitating meshing and transmission with the rack 4-1 on the baffle 4. This opening 1-7 can also be referred to as the exposure port. The power source 2 is primarily a rotary drive device, typically an electric motor, but other rotary drive devices such as a hydraulic motor can also be used. The electric drive device and the gear 3 can be directly connected or transmitted through a transmission mechanism, such as a gear set. It should be noted that the gear 3 does not need to be completely exposed through 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 3 needs to be exposed through the opening 1-7; however, the entire gear 3 can also be completely exposed. The opening 1-7 is located on the housing surface 1-5 so that the gear 3 can protrude outside the housing 1 to mesh with the rack 4-1 on the outside of the housing 1.

[0044] 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, 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 5 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 5.

[0045] The baffle 4 is fixed with a rack 4-1 that meshes with the gear 3. When the power source 2 drives the gear 3 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 or open the discharge port 7-1.

[0046] Specifically, as shown in Figure 3, the baffle 4 has a feed inlet 4-2. Driven by the gear 3, the baffle 4 can move to either connect the feed inlet 4-2 with the discharge outlet 7-1 or block the discharge outlet 7-1. When the baffle 4 is moved to connect the feed inlet 4-2 with the discharge outlet 7-1, the material from the discharge outlet 7-1 can flow out through the feed inlet 4-2 to achieve discharge. When the baffle 4 is moved to block the discharge outlet 7-1, the material from the discharge outlet 7-1 is blocked by the baffle 4, thereby sealing and preserving the powder in the powder hopper to prevent the powder from getting damp or clumping.

[0047] If the baffle 4 is restricted relative to the housing 1, it can move between a first position where the discharge port 7-1 is connected to the baffle 4 and a second position where the discharge port 7-1 is not connected to the baffle 4. This can be achieved by the housing 1 or the support tray 5 (described later), restricting the baffle 4 to slide only relative to the housing 1 in the direction of movement (X1, X2). As shown in Figure 6, it can slide from the second position to the first position along the X1 direction to open the discharge port; and it can slide from the first position to the second position along the X2 direction to close the discharge port. One example is as follows: if the gear 3 rotates in the forward direction, it can move the baffle 4 to the first position; if the gear 3 rotates in the reverse direction, it can move the baffle 4 to the second position. When the baffle 4 moves to the first position, the feed port 4-2 is connected to the discharge port 7-1. If they are aligned, the discharge port 7-1 will be open. When the baffle 4 moves to the second position, the feed port 4-2 and the discharge port 7-1 are staggered, and the solid part of the baffle 4 blocks the discharge port 7-1 so that the discharge port 7-1 is closed.

[0048] 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 3. This allows the baffle 4 to move when the output end of the power source 2 rotates, thereby opening and closing the discharge port 7-1. When powder dispensing is needed, the discharge port 7-1 is opened; when not dispensing, it is closed. This effectively prevents external air from prolonged contact with the powder at the discharge port 7-1, thus preventing powder agglomeration 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.

[0049] 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 5, which is detachably installed on the outside of the housing 1. The support tray 5 has a disc surface opposite to the discharge port 7-1, 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 5 under the drive of the power source 2.

[0050] In some embodiments, the support tray 5 can further restrict the range of motion of the baffle 4 while supporting it, as described above, to limit its movement between the first and second positions. The structure and shape of the support tray 5 are not limited; they can be configured as needed to achieve the aforementioned functions. As shown in Figure 4, in this embodiment, a portion of the outer periphery of the support tray 5 is adapted to the corresponding outer periphery of the housing 1. A receiving groove 5-3 is provided on the surface of the support tray 5 opposite to the baffle 4. As shown in Figure 6, the baffle 4 is placed in the receiving groove 5-3, restricting its movement to guide its movement along the X1 and X2 directions and restricting its movement in the forward and backward directions perpendicular to the X1 and X2 directions.

[0051] Preferably, the support tray 5 has an installation limiting surface 5-14, as shown in Figure 4. Protrusions can be formed on both sides, and the installation limiting surface 5-14 is formed on the side of the protrusion (the front side in the pushing direction). When the support tray 5 is pushed into place, it can abut against the housing 1 through the installation limiting surface 5-14 to prevent the support tray 5 from moving further forward.

[0052] In some embodiments, as shown in Figures 4 and 5, to facilitate powder conveying, the support tray 5 can simultaneously have a powder conveying channel 5-10, wherein the powder conveying channel 5-10 is positioned corresponding to the discharge port 7-1, such as being aligned. Specifically, the central axes of the discharge port 7-1 and the powder conveying channel 5-10 can coincide, and preferably the cross-section of the powder conveying channel 5-10 is slightly larger than the cross-section of the discharge port 7-1 to facilitate better material discharge. Specifically, when the material conveying port 4-2 coincides with the discharge port 7-1, their central axes also coincide. Furthermore, the discharge port 7-1, material conveying port 4-2, and powder conveying channel 5-10 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 discharge port 7-1, the conveying port 4-2, and the powder conveying channel 5-10 can be the same or different. For example, the discharge port 7-1 may be circular, while the conveying port and the powder conveying channel 5-10 may both have square cross-sections, preferably with a side length greater than the diameter of the discharge port 7-1. The powder conveying channel 5-10 can extend from the surface of the support tray 5 towards the discharge port 7-1.

[0053] As shown in Figure 5, at least one flat surface is formed on the lower side of the support tray 5, i.e., the side facing the platform, to serve as an abutment surface 5-13 for contacting the bottle neck. The lower end of the powder passage 5-10 is located at the abutment surface 5-13, and an arc-shaped protrusion 5-12 is formed on at least one side of the powder passage 5-10 to enlarge the abutment surface 5-13, increase the contact area between the abutment surface 5-13 and the bottle neck, thereby adapting to bottles of different diameters and preventing powder from floating out of the bottle neck due to partial gaps in the abutment surface.

[0054] In some embodiments, the support tray 5 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.

[0055] For ease of operation, a push-pull connection can be formed between the support tray 5 and the housing 1. This connection increases the load-bearing capacity between the support tray 5 and the housing 1, thereby improving the support effect on the baffle 4. In the push-pull direction, an elastic limiting structure can be used to further limit relative movement. Under significant external force, the elastic limiting structure can be released, allowing the support tray 5 to be detached.

[0056] The support tray 5 is connected to the housing 1 via a push-pull mechanism along a preset direction (front-back direction), as shown in Figure 6. In the forward direction, the support tray 5 can be pushed into the corresponding position on the housing 1; while in the rearward direction, the support tray 5 can be pulled out from the housing 1 to separate from it. The preset direction is perpendicular to and parallel to the moving direction of 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. The 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 3, so that when the support tray 5 is assembled, the rack 4-1 and the gear 3 move relative to each other along the axial direction of the gear 3 to complete the meshing. Both the gear 3 and the rack 4-1 can be straight-tooth structures.

[0057] In some embodiments, to facilitate push-pull connection, the housing 1 may have support shoulders 1-3 on both sides of the support tray 5 for supporting the support tray 5 (shown in FIG1). At the same time, the housing wall with the support shoulders 1-3 may be able to support the tray 5 to be further limited in the moving direction (X1, X2 direction) of the baffle 4, such as limiting the support tray 5 in the moving direction of the baffle 4.

[0058] As shown in Figure 4, the support tray 5 can have support ear plates 5-7 on both sides that overlap the upper side of the support shoulder 1-3 to support the support tray 5. One end of the support ear plate 5-7 has an upwardly inclined guide plate 5-8, so that when the support tray 5 is inserted, the lower side of the guide plate 5-8 can abut against the support shoulder 1-3 to guide the support ear plate 5-7 to move to the upper side of the support shoulder 1-3.

[0059] In some embodiments, each side of the support ear plate 5-7 may include two parallel supports arranged vertically, with the two support ear plates 5-7 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 5 and the support shoulder 1-3 and improves the installation efficiency of the support tray 5.

[0060] Furthermore, for ease of fixing, as shown in Figure 4, one end of the support tray 5 (the front end of the support tray 5 in the direction of being pushed into the housing) can be inserted into the housing 1, and the other end of the support tray 5 (the rear end of the support tray 5 in the direction of being pushed into the housing) can be snapped into the housing 1. Specifically, it can be snapped into place by slots 1-2 and protrusions 5-5 to improve the stability of the support tray structure and facilitate connection.

[0061] In some embodiments, an elastic limiting device 8 may be further provided as the aforementioned elastic limiting structure. This elastic limiting device 8 prevents the support tray 5 from moving outward after it has been inserted into place.

[0062] Specifically, the elastic limiting device 8 may include a ball bearing and an elastic element (not shown in the figure) for elastically supporting the ball bearing. The ball bearing can be compressed by the elastic element and retracted into a ball bearing mounting groove on the surface of the housing 1, or the ball bearing can protrude from the ball bearing mounting groove under the elastic restoring force of the elastic element. After the support tray 5 is installed in place, the ball bearing can enter the limiting position under the action of the elastic element, that is, it is located in the receiving groove 5-3 and abuts against the limiting groove wall 5-11 of the receiving groove 5-3 to prevent the support tray 5 from leaving the installation position. When the external force on the support tray 5 is relatively large, it is sufficient to make the limiting groove wall 5-11 push the ball bearing to overcome the elastic deformation force of the elastic element, so that the ball bearing leaves the limiting position.

[0063] Furthermore, for ease of operation, the support tray 5 can be provided with hand holes 5-6 to facilitate the application of force to the support tray 5.

[0064] The support tray 5 includes a receiving groove 5-3 for accommodating the baffle 4, wherein the groove wall of the receiving groove 5-3 can serve as the aforementioned limiting groove wall 5-11. For example, when the support tray 5 is in the installation position, the aforementioned ball can be located in the receiving groove 5-3 to abut against the limiting groove wall 5-11 of the receiving groove 5-3.

[0065] In some embodiments, when the support tray 5 is provided with a receiving groove 5-3, at least one of the groove walls of the receiving groove 5-3 can protrude outward to form an expansion groove 5-4 for dust accumulation. Specifically, both sides of the receiving groove 5-3 along the moving direction of the baffle 4 can have outwardly expanding expansion grooves 5-4, and preferably the expansion grooves 5-4 are arc-shaped grooves to improve structural strength and reduce the number of corners, thus facilitating the cleaning of accumulated dust.

[0066] In some embodiments, the discharge port 7-1 can be located at the bottom of the powder hopper 7; the powder hopper 7 is provided with a powder discharge screw 9 for pushing the powder out, and the powder discharge screw 9 extends to the discharge port 7-1. The powder is pushed towards the discharge port 7-1 by the rotation of the powder discharge screw 9. At this time, the powder discharge screw 9 is equivalent to a screw conveyor.

[0067] The discharge port 7-1 is generally positioned opposite the support platform 6, which is used to support containers such as baby bottles. For ease of arrangement, a suspended shell plate 1-4 can be provided, parallel to the support platform 6 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 5 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.

[0068] Based on the powder dispensing device provided in the above embodiments, this utility model also provides an automatic brewing machine. 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 a 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.

[0069] 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 5 of the powder dispensing device is provided with a liquid passage 5-1. One end of the liquid passage 5-1 is provided with a liquid inlet interface 5-2 and the other end is provided with a liquid outlet 5-9. The liquid inlet interface 5-2 is connected to the outlet of the liquid supply device.

[0070] It should be noted that the automatic powder preparation machine exemplified in this embodiment can be used not only for preparing milk powder, but also for preparing other types of powders.
