[0032] Reference Figure 1-7 The figure shows a preferred embodiment of the present invention.

[0033] The pudding machine in this embodiment is suitable for taking milk powder and various edible nutritional powders.

[0034] The gouache machine includes a main body equipped with a water tank 101 for receiving water, a powder hopper 300, and an outlet pipe for discharging heated water. The powder hopper 300 is connected to and communicates with an inverted powder tank. The outlet pipe is connected to the water tank 101 and is equipped with a heating structure for heating the water in the outlet pipe to a set temperature.

[0035] Alternatively, the water tank and the water outlet pipe may not be provided, and the water powder machine may discharge the powder alone without discharging the water at the same time. The powder discharged by the user may be poured into the water by himself for mixing to form a powder liquid.

[0036] The top of the powder bin 300 protrudes upward to form an enclosure ring 308 located above the machine body. The enclosure ring 308 surrounds and forms an insertion area for the powder can to be inserted upside down, so that the powder can is easily inserted upside down into the powder bin 300.

[0037] The powder silo 300 has a silo cavity 3012 connected to the inverted powder tank, and the machine body is provided with a powder outlet 3011 connected to the silo cavity 3012, and the powder outlet 3011 is used to discharge the powder in the silo cavity 3012; the powder silo 300 is provided with a rotating quantitative turntable 302, and the quantitative turntable 302 discharges the powder in the silo cavity 3012 into the powder outlet 3011 in a quantitative manner by rotation.

[0038] In the above-mentioned gouache machine, the quantitative turntable 302 rotates to discharge the powder in the powder bin 300 in a quantitative manner; the powder tank is arranged in an inverted shape on the machine body, which is convenient for discharging the powder. There is no need to suck the powder in the powder tank, and the powder can fall into the powder bin 300 by itself. The structure is simple and the powder is discharged smoothly.

[0039] After the gouache machine is started, the powder discharging parameters can be set. According to the powder discharging parameters, the quantitative turntable 302 rotates to discharge the powder in the powder bin 300 through the powder outlet 3011 in a quantitative manner.

[0040] A controller is provided within the machine body, and a control area is provided on the machine body, the control area being electrically connected to the controller. The powder discharge parameters are set via the control area. The control area can be provided with a display screen, which can be a touch screen display that can be operated by touch and can also display the powder parameters. Alternatively, buttons can be provided in the control area, etc.

[0041] The machine body has an operating area for placing the container 200 , and the powder outlet 3011 is located above the operating area. The powder discharged from the powder outlet 3011 enters the container 200 in the operating area.

[0042] Containers 200 such as cups or milk powder cups can be placed in the operation area. The operation area is provided with a base, and a rotating table is provided on the base. The rotating table is provided with a groove for placing the container 200. The container 200 is placed in the groove of the rotating table. When the machine body is in the process of discharging powder, the rotating table can drive the container 200 to rotate, so that the powder and water entering the container 200 are mixed more evenly.

[0043] The powder tank has a ring-shaped tank wall, which encloses a tank cavity with a top opening and in which powder is stored. The bottom of the enclosing ring 308 is provided with an annular groove 3081 with a top opening. The annular groove 3081 is formed at the bottom of the tank insertion area and is arranged around the circumference of the enclosing ring 308. When the powder tank is inverted and inserted into the tank insertion area, the tank wall is inserted into the annular groove 3081, and the top opening of the tank cavity is arranged toward the powder cavity.

[0044] By providing the annular groove 3081 , the tank wall and the annular groove 3081 can be firmly fitted together, so that the powder tank can be firmly inserted into the powder bin 300 .

[0045] An inner ring wall 309 is provided at the bottom of the insertion area, the bottom of the inner ring wall 309 is connected to the bottom of the enclosing ring, the top of the inner ring wall 309 is spaced apart from the enclosing ring 308, and an annular groove 3081 is formed between the inner ring wall 309 and the enclosing ring 308; when the powder can is inverted and inserted into the insertion area, the inner ring wall 309 is inserted into the tank cavity from the top opening of the tank cavity, and the inner ring wall 309 abuts against the inner side wall of the top opening of the tank cavity.

[0046] In this way, the enclosing wall 308 and the inner ring wall 309 clamp the wall of the powder tank towards each other, making the powder tank more stable when placed upside down.

[0047] An inclined surface is formed on the top of the inner ring wall 309, and the inclined surface is arranged downwardly along the direction from the enclosing ring 308 to the inner ring wall 309, so as to facilitate guiding the powder in the powder tank into the powder bin 300, and when the powder tank is separated from the powder bin 300, it prevents the powder from remaining on the inner ring wall 309.

[0048] The top of the machine body has a concave cavity in which the powder supply bin 300 is inserted. The powder bin 300 includes a bin body 301, which has the above-mentioned bin cavity 3012. The bin cavity 3012 passes through the top of the bin body 301 to form a top opening. The bottom of the bin body 301 is provided with the powder outlet 3011.

[0049] The quantitative rotating disk 302 is provided with a plurality of quantitative grooves 3021 extending vertically therethrough and accommodating a quantitative amount of powder. The quantitative grooves 3021 are arranged at intervals along the circumference of the quantitative rotating disk 302 , and a shielding portion 3022 is provided between adjacent quantitative grooves 3021 to cover the powder outlet 3011 ;

[0050] When the powder tank is inverted on the machine body, the powder tank communicates with the chamber 3012 through the top opening. During the rotation of the metering turntable 302, when the metering groove 3021 communicates with the powder outlet 3011, the measured powder in the metering groove 3021 is discharged through the powder outlet 3011. When the metering groove 3021 and the powder outlet 3011 are offset, the shielding portion 3022 covers the powder outlet 3011.

[0051] Since the volume of the quantitative groove 3021 is fixed, the amount of powder formed in the quantitative groove 3021 is fixed. When the quantitative groove 3021 equipped with powder is rotated to be connected with the powder outlet 3011, the powder in the quantitative groove 3021 falls through the powder outlet 3011. When the quantitative groove 3021 and the powder outlet 3011 are misaligned and not connected, the powder outlet 3011 is covered by the shielding portion 3022. In this way, the powder discharged from the powder outlet 3011 can be quantitative.

[0052] A fixed stator brush 303 is provided on the quantitative turntable 302, and a powder scraping brush 3031 is provided at the end of the stator brush 303. The powder scraping brush 3031 abuts against the quantitative turntable 302 and is located above the powder outlet 3011; in step 2), during the rotation of the quantitative turntable 302, when the quantitative groove 3021 and the powder scraping brush 3031 overlap up and down, as the powder scraping brush 3031 and the positioning groove rotate relative to each other, the powder scraping brush 3031 scrapes off the powder above the quantitative groove 3021, so that the powder discharged through the powder outlet 3011 is the quantitative powder in the quantitative groove 3021; when the quantitative groove 3021 passes over the powder outlet 3011, and is misaligned with the powder outlet 3011 and the powder scraping brush 3031, the powder in the chamber 3012 is filled in the quantitative groove 3021.

[0053] When the quantitative turntable 302 is rotating, the stator brush 303 is fixed, and the powder scraping brush 3031 will pass through the powder on the quantitative turntable 302. When the powder scraping brush 3031 is hanging on the top of the quantitative groove 3021, the powder above the quantitative groove 3021 will be brushed out, so that when the quantitative groove 3021 is connected to the powder outlet 3011, there is powder only in the quantitative groove 3021, and there is no powder on the quantitative groove 3021.

[0054] Two scraping brushes 3031 are provided at the end of the stator brush 303. The two scraping brushes 3031 are arranged at intervals along the rotation direction of the quantitative turntable 302. The two scraping brushes 3031 are respectively located on both sides of the powder outlet 3011; a spacing area 3032 is provided between the two scraping brushes 3031, and the spacing area 3032 is larger than the width of the quantitative groove 3021.

[0055] During the rotation of the metering turntable 302, when the metering groove 3021 is aligned vertically with the powder outlet 3011, the metering groove 3021 is located in the spacing area 3032. Thus, when the metering groove 3021 is in communication with the powder outlet 3011, the powder in the powder bin 300 will not enter the spacing area 3032 due to the restriction of the two powder scraping brushes 3031, that is, it will not be discharged through the powder outlet 3011. This ensures that only the powder in the metering groove 3021 in communication with the powder outlet 3011 can be discharged through the powder outlet 3011 at a time, and the discharged powder is quantitatively guaranteed.

[0056] In this embodiment, an elastic stirring block 3033 is provided on the stator brush 303, and the stirring block 3033 is arranged in the spacing area 3032, between the two powder scraping brushes 3031. The upper end of the stirring block 3033 is docked on the stator brush 303, and the lower end of the stirring block 3033 is extended downward. When the metering groove 3021 rotates to the spacing area 3032 and is connected with the powder outlet 3011, the lower end of the stirring block 3033 enters the metering groove 3021, breaking up the powder in the metering groove 3021 so that the powder in the metering groove 3021 falls into the powder outlet 3011.

[0057] The stirring block 3033 comprises an upper section 601 positioned above the dosing groove 3021 and a lower section 602 extending through the dosing groove 3021. The upper section 601 is provided with a plurality of transversely arranged deformation grooves 6011. The lower section 602 comprises a film section 6021 that elastically deforms reciprocally under pressure. Airbag layers 6023 are provided on either side of the film section 6021, projecting outward. The airbag layers 6023 are arranged in a bulging shape. The outer periphery of the airbag layer 6023 abuts against the surface of the lower section 602, with the middle portion of the airbag layer 6023 facing the film section 6021. A deformation space 6022 is enclosed between the airbag layer 6023 and the film section 6021.

[0058] When the lower section 602 is inserted into the quantitative groove 3021 and the quantitative turntable 302 is in the process of rotation, the two airbag layers 6023 are elastically deformed by the pressure change, and the film layer is driven to elastically deform, and the deformation space 6022 is elastically deformed.

[0059] By setting the airbag layer 6023, when the airbag layer 6023 is deformed, the deformation space 6022 is also deformed, thereby pushing the film layer to deform, and the entire lower section 602 is in the process of elastic deformation, so that the powder in the quantitative groove 3021 can be better broken up and the powder can be prevented from adhering to the lower section 602.

[0060] A rotating stirring disc 304 is provided in the middle of the chamber 3012 . A plurality of hollow areas 3041 passing through the stirring disc 304 are provided in the stirring disc 304 . The plurality of hollow areas 3041 are arranged at intervals along the circumference of the stirring disc 304 .

[0061] When the quantitative turntable 302 rotates, the stirring turntable 304 rotates synchronously, and the stirring turntable 304 stirs the powder in the chamber 3012. The stirring turntable 304 stirs the powder in the chamber 3012, which can break up the powder in the chamber 3012 and prevent it from agglomerating, thereby facilitating the flow of the powder in the chamber 3012.

[0062] In this embodiment, a door frame 306 is provided in the chamber 3012, two powder dropout ports 3061 are provided in the door frame 306, and a crossbeam 3062 is provided between the two powder dropout ports 3061; a swinging piece 305 for covering or opening the powder dropout port 3061 is connected to the door frame 306, the inner end of the swinging piece 305 is hinged to the transverse direction, and the outer end of the swinging piece 305 is freely arranged; a limit strip 307 is extended downward from the outer periphery of the door frame 306, and a limit block 3071 is provided on the limit strip 307 for limiting the swinging piece 305 from swinging downward to the extreme position.

[0063] When the powder tank is inverted on the powder bin 300, the outer end of the swing plate 305 swings downward away from the bin door frame 306 to the limit block 3071, the powder dropout port 3061 opens, and the powder in the powder tank enters the bin cavity 3012 through the powder dropout port 3061; when the powder bin 300 is separated from the machine body and when the powder bin 300 is placed in the forward direction, the outer end of the swing plate 305 swings toward the bin door frame 306 and abuts against the bin door frame 306, the swing plate 305 closes the powder dropout port 3061, and restricts the powder in the bin cavity 3012 from being discharged from the powder dropout port 3061 in the reverse direction.

[0064] When the powder tank is placed on the powder bin 300, the outer end of the swing plate 305 swings downward away from the bin door frame 306 due to the weight of the swing plate 305. At this time, the powder outlet 3061 is opened, and the powder in the powder tank enters the bin cavity 3012. When the powder tank needs to be replaced, the powder bin 300 and the powder tank are removed from the machine body. At this time, the powder tank is placed upright and the powder bin 300 is inverted. Only then, under the action of the weight of the swing plate 305, the outer end of the swing plate 305 swings toward the bin door frame 306, thereby closing the powder outlet 3061. During the process of changing the powder tank, the powder in the bin cavity 3012 will not be discharged backward through the powder outlet 3061, thus preventing the powder in the bin cavity 3012 from being discharged during the process of changing the powder tank.

[0065] In this embodiment, the swing piece 305 has an upwardly facing top surface, on which a plurality of flexible membrane strips 500 arranged in strips are provided. The flexible membrane strips 500 extend from the inner end to the outer end of the swing piece 305, and a closed strip-shaped cavity 501 is formed between the flexible membrane strips 500 and the top surface.

[0066] A sheet-shaped elastic strip 502 is provided in the strip-shaped cavity 501 and extends along the length of the strip-shaped cavity 501. The outer end of the elastic strip 502 is fixedly connected to the top surface of the swinging piece 305, and the inner end of the elastic strip 502 is connected to the flexible membrane strip 500. The elastic strip 502 is arranged to be tilted upward and away from the top surface of the swinging piece 305 along the direction from the outer end to the inner end of the strip-shaped cavity 501. An elastic block is provided on the limit block 3071.

[0067] The outer end of the swing plate 305 swings downward and abuts against the elastic block. The powder in the powder tank passes through the powder drop port 3061 and falls downward into the chamber 3012 along the top surface of the swing plate 305. As the pressure on the swing plate 305 changes, the elastic block drives the swing plate 305 to swing up and down, and the elastic strip 502 elastically deforms up and down relative to the top surface of the swing plate 305, driving the flexible membrane strip 500 to fluctuate up and down.

[0068] By providing a flexible diaphragm and an elastic strip 502 in the strip-shaped cavity 501 enclosed by the flexible diaphragm, when the pressure of the powder falling on the swinging piece 305 changes, the flexible diaphragm fluctuates up and down under the drive of the elastic strip 502, which can better push the powder on the top surface of the swinging piece 305 to fall down, avoiding the formation of powder accumulation on the top surface.

[0069] By providing the elastic block, when the pressure of the powder on the top surface changes, the elastic block drives the swing piece 305 to swing up and down, thereby better shaking off the powder on the top surface.

[0070] The above description is only 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 in the scope of protection of the present invention.
