[0002] As a household appliance designed to simplify the infant feeding process and improve the convenience and accuracy of formula preparation, formula makers have received widespread attention and application in recent years. One of their core functions is to automatically and quantitatively dispense formula to ensure accurate concentration of the prepared formula each time, meeting the health needs of infants.

[0003] Currently, existing milk powder dispensing devices typically employ a spiral propulsion mechanism. This involves a motor driving a spiral rod to rotate, pushing the milk powder forward along a spiral groove. The dispensing amount is indirectly controlled by adjusting the number of rotations or the time taken. This device has the following drawbacks: the spiral rod exerts compression and shearing forces on the milk powder during the feeding process, easily causing the fine-textured milk powder to clump and clog, affecting dispensing accuracy and smoothness. Therefore, there is an urgent need to research a milk powder dispensing device for milk powder preparation machines to solve these problems. Utility Model Content

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figure 1-3As shown, this utility model is a milk powder dispensing device for a milk powder mixing machine, including a conventional tank 1 and a feeding assembly 2 installed in the bottom of the tank 1; the bottom wall of the tank 1 is integrally formed with a vertically arranged feeding hopper 101; the upper edge of the feeding hopper 101 abuts against the edge of the bottom wall of the tank 1, and the central axis of the tank 1 is located at the upper edge of the feeding hopper 101; the bottom of the feeding hopper 101 has a vertically arranged discharge port 102; the discharge port 102 has a cylindrical structure; a carrying box 3 is arranged below the feeding hopper 101; the top wall and bottom wall of the carrying box 3 are respectively provided with a connection port 301 and a circular discharge port 302; the connection port 301 and the discharge port 302... 02. Offset setting; the connection port 301 has a cylindrical structure; the connection port 301 is sleeved on the outer periphery of the discharge port 102, and the connection port 301 and the discharge port 102 are connected by bolts; a metering cylinder 4 is vertically arranged inside the carrier box 3; the upper and lower ends of the metering cylinder 4 slide against the top and bottom walls of the carrier box 3 respectively; a horizontally arranged baffle 401 is integrally formed on the edge of the upper end of the metering cylinder 4; the upper surface of the baffle 401 slides against the top wall of the carrier box 3; when the metering cylinder 4 and the discharge port 302 are coaxially arranged, the upper surface of the baffle 401 abuts against the lower end of the discharge port 102; the inner diameter of the metering cylinder 4 is slightly larger than the inner diameter of the discharge port 102 and the inner diameter of the discharge port 302. In use, milk powder is poured into can 1, and then the milk powder in can 1 enters the hopper 101. The pushing component 2 accelerates the flow of milk powder from can 1 into the hopper 101. When the measuring cylinder 4 is coaxially aligned with the discharge port 102, the milk powder in the hopper 101 is discharged into the measuring cylinder 4 through the discharge port 102. After the measuring cylinder 4 is full of milk powder, the measuring cylinder 4 is driven to move linearly within the carrier box 3, causing the measuring cylinder 4 to gradually align with the discharge port 302. During the movement of the measuring cylinder 4 from the discharge port 102 to the discharge port 302, the upper surface of the baffle 401... The lower end of the metering cylinder 4 abuts against the discharge port 102, thus blocking the discharge port 102 and preventing milk powder from leaking into the carrier box 3. After the lower end of the metering cylinder 4 is connected to the discharge port 302, the milk powder in the metering cylinder 4 is discharged through the discharge port 302, thereby realizing the quantitative dispensing of milk powder. This not only avoids the problems of milk powder clumping and blockage caused by the extrusion of the screw rod in the prior art, but also ensures the smoothness of milk powder dispensing and the quantitative accuracy of milk powder. In addition, the volume of the metering cylinder 4 is set according to the conventional technical means in the field and belongs to the prior art, which will not be described in detail here.

[0027] Among them, such as Figure 2 and Figure 4As shown, the upper edge of the feeding hopper 101 has a vertically protruding mounting hole 103 coaxially arranged with the tank body 1; the pushing assembly 2 includes a rotating shaft 201 vertically rotatably connected to the mounting hole 103; multiple vertically arranged pushing blades 202 are radially welded to the upper end of the rotating shaft 201; the lower edges of the multiple pushing blades 202 slide against the bottom wall of the tank body 1. In use, rotating the rotating shaft 201 drives the pushing blades 202 to rotate inside the tank body 1, and the pushing blades 202 push the milk powder in the tank body 1 into the feeding hopper 101, ensuring the milk powder dispensing effect.

[0028] Example 2:

[0029] Based on Example 1, as follows Figure 2-3 and Figure 5-6As shown, a protective shell 104 is integrally formed in the upper part of the tank body 1; the top of the protective shell 104 is an open structure, and a top cover 105 is horizontally bolted to the open top of the protective shell 104; rectangular receiving openings 303 are provided on the opposite side walls of the carrier box 3; the two receiving openings 303 are respectively located on the opposite outer sides of the connecting port 301 and the unloading port 302; the baffle 401 can slide through one receiving opening 303; a reciprocating drive assembly 5 is installed on one side of the carrier box 3; the reciprocating drive assembly 5 passes through the other receiving opening 303 and is connected to the metering cylinder 4; the reciprocating drive assembly 5 can drive the metering cylinder 4 to move linearly within the carrier box 3; the reciprocating drive assembly 5 includes a support seat 501 vertically bolted to the bottom wall of the tank body 1; a cylindrical cam 502 is horizontally rotatably connected to the support seat 501; a push-pull rod 503 is horizontally arranged below the cylindrical cam 502 and parallel to it; the push-pull rod 503... 03 Slidingly inserted into the support base 501; one end of the push-pull rod 503 is vertically bolted to the transmission column 504; the upper end of the transmission column 504 is slidably inserted into the working groove of the cylindrical cam 502; the other end of the push-pull rod 503 passes through another receiving port 303 and is bolted to the movable sleeve 505; the movable sleeve 505 is bolted to the outer periphery of the metering cylinder 4; a tension spring 511 is sleeved on the push-pull rod 503; the two ends of the tension spring 511 are bolted to the support base 501 and the movable sleeve 505 respectively; a drive motor 506 is provided above the cylindrical cam 502; the drive motor 506 is horizontally bolted to the protective housing 104; the output shaft of the drive motor 506 passes through the circumferential side wall of the tank 1 and is keyed to the first pulley 507; the first pulley 507 is connected to the second pulley 508 through the synchronous belt drive; the second pulley 508 is keyed to one end of the cylindrical cam 502. In use, the drive motor 506 drives the cylindrical cam 502 to rotate via the first pulley 507 and the second pulley 508. This causes the cylindrical cam 502 to drive the push-pull rod 503 to reciprocate linearly via the transmission column 504, thereby realizing the linear movement of the metering cylinder 4 within the carrier box 3. This allows the metering cylinder 4 to switch positions between the discharge port 101 and the unloading port 301, ensuring the effective dispensing of milk powder.

[0030] Among them, such as Figure 4 and Figure 7As shown, the working groove of the cylindrical cam 502 includes a pair of coaxially arranged arc-shaped channels 5021 and a pair of spiral channels 5022 disposed between the two arc-shaped channels 5021; the two arc-shaped channels 5021 are respectively disposed at both ends of the cylindrical cam 502; when one arc-shaped channel 5021 is located at the upper part of the cylindrical cam 502, the other arc-shaped channel 5021 is located at the lower part of the cylindrical cam 502; both ends of any spiral channel 5022 are respectively connected to the ends of the two arc-shaped channels 5021 that are close to each other; the other end of the cylindrical cam 502 is keyed to a first bevel gear 509; a second bevel gear 510 meshes with the first bevel gear 509; the second bevel gear 510 is keyed to the lower end of the rotating shaft 201. In use, the working groove of the cylindrical cam 502 is designed as a pair of coaxially arranged arc-shaped channels 5021 and a pair of spiral channels 5022 disposed between the two arc-shaped channels 5021. The two arc-shaped channels 5021 are respectively disposed at both ends of the cylindrical cam 502, and the two ends of the spiral channels 5022 are respectively connected to the ends of the two arc-shaped channels 5021. This allows the transmission column 504 to slide within an arc-shaped channel 5021 when the metering cylinder 4 and the discharge port 102 are coaxially arranged. At this time, the transmission column 504 does not move in a straight line, causing the metering cylinder 4 and the discharge port 102 to remain coaxial for a period of time. This not only ensures that the metering cylinder 4 is full of milk powder, but also ensures the conveying effect of the milk powder. When the metering cylinder 4 and the discharge port 302 are set coaxially, the transmission column 504 slides in another arc-shaped channel 5021. At this time, the transmission column 504 also does not move in a straight line, causing the metering cylinder 4 and the discharge port 302 to remain coaxial for a period of time, effectively ensuring the release effect of the milk powder in the metering cylinder 4.
