[0030] Reference Figures 1-7 The image shows a preferred embodiment of the present invention.

[0031] The powder dispenser in this embodiment is suitable for dispensing milk powder and various edible nutritional powders.

[0032] The water-based powder dispenser has a quantitative powder dispensing structure, including a machine body. The machine body includes a powder hopper 300, which can be connected to and communicates with an inverted powder tank. The powder hopper 300 has a cavity 3012 that communicates with the inverted powder tank. The machine body is provided with a powder outlet 3011 that communicates with the cavity 3012. The powder outlet 3011 is used to discharge the powder from the cavity 3012.

[0033] The powder silo 300 is equipped with a rotating quantitative turntable 302. The quantitative turntable 302 discharges the powder in the silo cavity 3012 into the powder outlet 3011 by rotating. The quantitative turntable 302 is located above the powder outlet 3011.

[0034] The metering turntable 302 is provided with multiple metering grooves 3021 that run vertically through and accommodate metered powder. The multiple metering grooves 3021 are arranged at intervals along the circumference of the metering turntable 302, and there is a blocking part 3022 between adjacent metering grooves 3021 to cover the powder outlet 3011.

[0035] When the powder tank is inverted on the machine body, it connects to the hopper 3012 through the top opening. During the rotation of the metering turntable 302, when the metering trough 3021 is connected to the powder outlet 3011, the metered powder in the metering trough 3021 is discharged through the powder outlet 3011. When the metering trough 3021 and the powder outlet 3011 are misaligned, the blocking part 3022 covers the powder outlet 3011.

[0036] Since the volume of the metering tank 3021 is fixed, the amount of powder formed in the metering tank 3021 is fixed. When the metering tank 3021 containing powder rotates to connect with the powder outlet 3011, the powder in the metering tank 3021 falls through the powder outlet 3011. When the metering tank 3021 and the powder outlet 3011 are misaligned and not connected, the powder outlet 3011 is covered by the shielding part 3022. In this way, the powder discharged from the powder outlet 3011 can be metered.

[0037] The quantitative powder dispensing structure of the water-based powder machine described above involves a rotating quantitative turntable 302 that dispenses a measured amount of powder from the quantitative trough 3021 through the powder outlet 3011. When the quantitative trough 3021 and the powder outlet 3011 are misaligned, the blocking part 3022 seals the powder outlet 3011, preventing the powder in the powder hopper 300 from falling out of the powder outlet 3011. This achieves the quantitative powder dispensing effect of the water-based powder machine. Furthermore, by setting an inverted powder tank, there is no need to pump the powder from the powder tank; the powder simply falls into the powder hopper 300 on its own. The structure is simple, and the powder is discharged smoothly.

[0038] In this embodiment, the machine body is equipped with a water tank 101 for holding water, and a water outlet pipe is provided in the machine body to discharge the heated water. The water outlet pipe is connected to the water tank 101, and a heating structure is provided on the water outlet pipe to heat the water in the water outlet pipe to a set temperature; the water is discharged from the water outlet pipe, and the water is mixed with the powder to form a powder liquid.

[0039] When the water powder machine is started, the powder output parameters and water output parameters can be set. According to the powder output parameters, the metering turntable 302 rotates and discharges the powder in the powder hopper 300 through the powder outlet 3011 in a metered manner. According to the water output parameters, the water outlet pipe discharges a metered amount of water.

[0040] The machine body contains a controller, and the machine body also has a control area, which is electrically connected to the controller. The powder output parameters and water output parameters are set through the control area. A display screen, which can be a touch screen, can be installed in the control area to display water and powder parameters via touch operation. Alternatively, buttons can be installed in the control area, etc.

[0041] The machine body has an operating area for placing a container 200. The water outlet pipe has a water outlet for discharging water. The powder outlet 3011 and the water outlet are located above the operating area. The powder discharged from the powder outlet 3011 and the water discharged from the water outlet enter the container 200 in the operating area respectively.

[0042] The operating area can hold containers such as cups or milk powder cups 200. The operating area is equipped with a base, and a rotating platform is set on the base. The rotating platform has a groove for placing the container 200. When the machine is dispensing powder and water, the rotating platform can drive the container 200 to rotate, so that the powder and water entering the container 200 are mixed more evenly.

[0043] Along the radial direction of the metering turntable 302, the radial width of the metering groove 3021 is smaller than the radial width of the powder outlet 3011. Along the circumferential direction of the metering turntable 302, the circumferential width of the metering groove 3021 is smaller than the circumferential width of the powder outlet 3011.

[0044] In this way, when the metering trough 3021 is connected to the powder outlet 3011, it is ensured that the entire metering trough 3021 is completely aligned vertically with the powder outlet 3011 during the intermediate process, and the metering trough 3021 and the powder outlet 3011 are connected vertically as a whole.

[0045] In this embodiment, the metering turntable 302 has a recessed annular groove arranged around the circumference of the metering turntable; the metering turntable 302 has a bottom wall located below the bottom of the annular groove, the bottom wall has a shielding portion 3022, and the metering groove 3021 is formed in the bottom wall.

[0046] In this way, the powder in the hopper 3012 can more easily enter the metering tank 3021, and after the powder in the metering tank 3021 falls, it is easier for the powder to fill the metering tank 3021.

[0047] The annular groove has an inner ring sidewall on its inner side and an outer ring sidewall on its outer side. The inner ring sidewall, the bottom wall, and the outer ring sidewall together form the annular groove. Along the top-to-bottom direction, the inner ring sidewall is inclined toward the outer ring sidewall, and the outer ring sidewall is arranged perpendicular to the bottom wall.

[0048] In this way, the powder placed in the annular groove is more easily filled into the metering groove 3021 after the powder is discharged, under the inclined guidance of the inner ring sidewall.

[0049] In this embodiment, the inner side of the metering groove 3021 is offset from the inner ring sidewall, and the outer side of the metering groove 3021 is vertically aligned with the outer ring sidewall. This ensures sufficient distance is maintained to guide the powder in the annular groove into the metering groove 3021 after the powder is discharged.

[0050] The top of the machine body has a recess for inserting the powder hopper 300. The powder hopper 300 includes a hopper body 301, and the hopper body 301 has the aforementioned hopper cavity 3012. The hopper cavity 3012 penetrates the top of the hopper body 301 to form a top opening, and the bottom of the hopper body 301 is provided with the powder outlet 3011.

[0051] A powder hopper 300 is inserted into the machine body. A mounting ring 308 extends upwards from the top of the powder hopper 300, forming a mounting area located above the hopper cavity 3012. When the powder hopper is placed on the hopper body 301, the powder hopper connects to the mounting ring 308, thus establishing a connection between the powder hopper and the powder hopper 300. The powder hopper has a wall, and the mounting ring 308 has an annular groove 3081. When the powder hopper is connected to the mounting ring 308, the wall of the powder hopper is embedded in the annular groove 3081.

[0052] A fixed stator brush 303 is provided on the quantitative turntable 302. The end of the stator brush 303 has a powder scraper 3031. The powder scraper 3031 abuts against the quantitative turntable 302 and is located above the powder outlet 3011.

[0053] During the rotation of the metering turntable 302, when the metering trough 3021 and the scraper brush 3031 overlap vertically, as the scraper brush 3031 rotates relative to the metering trough, the scraper brush 3031 scrapes away the powder above the metering trough 3021, so that the powder discharged through the powder outlet 3011 is the metered powder in the metering trough 3021; ​​when the metering trough 3021 passes the powder outlet 3011 and is misaligned with the powder outlet 3011 and the scraper brush 3031, the powder in the hopper cavity 3012 fills the metering trough 3021.

[0054] During the rotation of the metering turntable 302, the stator brush 303 remains stationary. The scraper brush 3031 scrapes the powder on the metering turntable 302. When the scraper brush 3031 scrapes the top of the metering trough 3021, it scrapes the powder above the metering trough 3021 away. This ensures that when the metering trough 3021 is connected to the powder outlet 3011, there is only powder in the metering trough 3021, and no powder on the metering trough 3021.

[0055] The stator brush 303 has two powder scraping brushes 3031 at its end. Along the rotation direction of the metering turntable 302, the two powder scraping brushes 3031 are arranged at intervals and are located on both sides of the powder outlet 3011. There is an interval area 3032 between the two powder scraping brushes 3031, and the interval area 3032 is larger than the width of the metering groove 3021.

[0056] During the rotation of the metering turntable 302, when the metering trough 3021 is vertically aligned with the powder outlet 3011, the metering trough 3021 is located in the interval region 3032. Thus, when the metering trough 3021 is connected to the powder outlet 3011, the powder in the powder hopper 300 will not enter the interval region 3032, and therefore will not be discharged through the powder outlet 3011, ensuring that only the powder in the metering trough 3021 connected to the powder outlet 3011 can be discharged through the powder outlet 3011 each time, and guaranteeing the metered amount of powder discharged.

[0057] In this embodiment, the stator brush 303 is provided with an elastic stirring block 3033. The stirring block 3033 is disposed in the interval region 3032, located between the two powder scraping brushes 3031. The upper end of the stirring block 3033 is connected to the stator brush 303, and the lower end of the stirring block 3033 extends downward. When the metering trough 3021 rotates into the interval region 3032 and communicates with the powder outlet 3011, the lower end of the stirring block 3033 enters the metering trough 3021 and disperses the powder in the metering trough 3021 so that the powder in the metering trough 3021 falls into the powder outlet 3011.

[0058] The stirring block 3033 has an upper section 601 located above the metering groove 3021 and a lower section 602 passing through the metering groove 3021; ​​the upper section 601 is provided with a plurality of transversely arranged deformable grooves 6011, and the lower section 602 has a thin film section 6021 that reciprocates under pressure; airbag layers 6023 are respectively provided on both sides of the thin film section 6021, and the airbag layers 6023 are arranged in a bulging shape; the outer periphery of the airbag layer 6023 is abutted on the surface of the lower section 602, the middle part of the airbag layer 6023 is arranged facing the thin film section 6021, and the airbag layer 6023 and the thin film section 6021 enclose a deformable space 6022;

[0059] When the lower section 602 is inserted into the metering groove 3021 and the metering turntable 302 is rotating, the two airbag layers 6023 are elastically deformed by pressure changes, which drives the film layer to elastically deform, and the deformation space 6022 elastically deforms.

[0060] By setting the airbag layer 6023, when the airbag layer 6023 deforms, the deformation space 6022 also deforms, thereby pushing the film layer to deform. The entire lower section 602 is in the process of elastic deformation, which can better disperse the powder in the metering tank 3021 and prevent the powder from adhering to the lower section 602.

[0061] The central part of the chamber 3012 is provided with a rotating stirring disc 304. The stirring disc 304 has multiple hollow areas 3041 that run vertically through it. The multiple hollow areas 3041 are arranged at intervals along the circumference of the stirring disc 304.

[0062] As the metering turntable 302 rotates, the stirring turntable 304 rotates synchronously, stirring the powder in the silo 3012. By stirring the powder in the silo 3012 with the stirring turntable 304, the powder in the silo 3012 can be broken up, preventing clumping and facilitating the flow of the powder in the silo 3012.

[0063] In this embodiment, a door frame 306 is provided in the cavity 3012, and two powder discharge ports 3061 are provided in the door frame 306. A crossbeam 3062 is provided between the two powder discharge ports 3061. A swing piece 305 for sealing or opening the powder discharge ports 3061 is connected to the door frame 306. The inner end of the swing piece 305 is hinged to the transverse side, and the outer end of the swing piece 305 is freely arranged. A limiting strip 307 extends downward from the outer periphery of the door frame 306. A limiting block 3071 is provided on the limiting strip 307 to limit the downward swing limit position of the swing piece 305.

[0064] When the powder tank is inverted on the powder hopper 300, the outer end of the swing plate 305 swings downward away from the hopper door frame 306 to the limit block 3071, and the powder discharge port 3061 opens, allowing the powder in the powder tank to enter the hopper cavity 3012 through the powder discharge port 3061. When the powder hopper 300 is separated from the machine body, and when the powder hopper 300 is placed upright, the outer end of the swing plate 305 swings towards the hopper door frame 306 and abuts against the hopper door frame 306. The swing plate 305 closes the powder discharge port 3061, preventing the powder in the hopper cavity 3012 from being discharged from the powder discharge port 3061 in the opposite direction.

[0065] When the powder container is placed on the powder hopper 300, due to the weight of the oscillating vane 305, the outer end of the oscillating vane 305 swings downward away from the hopper door frame 306. At this time, the powder discharge port 3061 opens, and the powder in the powder container enters the hopper cavity 3012. When the powder container needs to be replaced, the powder hopper 300 and the powder container are removed from the machine body as a whole. At this time, the powder container is placed upright, and the powder hopper 300 is inverted. Under the action of its own weight, the outer end of the oscillating vane 305 swings towards the hopper door frame 306, thereby closing the powder discharge port 3061. During the powder container replacement process, the powder in the hopper cavity 3012 will not be discharged in reverse through the powder discharge port 3061, thus preventing the powder in the hopper cavity 3012 from being discharged during the powder container replacement process.

[0066] In this embodiment, the swing plate 305 has an upward-facing top surface, on which a plurality of strip-shaped flexible membrane strips 500 are provided. The flexible membrane strips 500 extend along the direction from the inner end to the outer end of the swing plate 305, and the flexible membrane strips 500 and the top surface enclose a closed strip cavity 501.

[0067] A sheet-like elastic strip 502 is provided in the strip cavity 501, and the elastic strip 502 extends along the length direction of the strip cavity 501; the outer end of the elastic strip 502 is fixedly connected to the top surface of the swing plate 305, and the inner end of the elastic strip 502 is connected to the flexible membrane strip 500. Along the direction from the outer end to the inner end of the strip cavity 501, the elastic strip 502 is inclined upwards away from the top surface of the swing plate 305; an elastic block is provided on the limiting block 3071.

[0068] The outer end of the oscillating plate 305 swings downward and abuts against the elastic block. As the powder in the powder tank falls into the chamber 3012 through the powder discharge port 3061 and down along the top surface of the oscillating plate 305, the elastic block drives the oscillating plate 305 to swing up and down as the pressure on the oscillating plate 305 changes. The elastic strip 502 elastically deforms up and down relative to the top surface of the oscillating plate 305, driving the flexible membrane strip 500 to fluctuate up and down.

[0069] By setting a flexible diaphragm and setting an elastic strip 502 in the strip cavity 501 formed by the flexible diaphragm, when the pressure of the powder falling on the swing plate 305 changes, the flexible diaphragm will fluctuate up and down under the drive of the elastic strip 502, which can better push the powder on the top surface of the swing plate 305 to fall down and avoid the formation of powder accumulation on the top surface.

[0070] By setting an elastic block, when the pressure of the powder on the top surface changes, the elastic block drives the swing plate 305 to swing up and down, thereby better shaking off the powder on the top surface.

[0071] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
