Description

Technical Field

[0001] The invention belongs to the technical field of powder video storage and output, and in particular relates to a powder discharger structure. Background Art

[0002] A milk powder dispenser is a device that facilitates the use of milk powder and can automatically and quantitatively output milk powder. A milk powder dispenser generally uses a driving component (such as a motor or solenoid valve) to push a blocking plate to rotate, moving it away from the powder outlet to achieve powder discharge; when it stops, the torsion spring automatically resets the blocking plate to seal the powder outlet, isolating it from external moisture and pollutants. For example, the Chinese utility model patent document with the announcement number CN222091408U discloses a milk powder dispenser structure, which solves the problem that existing milk powder dispensers generally set a conveying structure in the storage barrel for storing milk powder, so that the milk powder is discharged from the powder outlet of the storage barrel, but cannot control the closing or opening of the powder outlet, resulting in the storage barrel being connected to the external environment for a long time, which easily causes the milk powder inside the storage barrel to be contaminated.

[0003] The powder discharging structure of the milk powder machine disclosed in the above patent document comprises a housing, a powder feeding structure for conveying milk powder is provided in the housing, the powder feeding structure has a powder outlet for discharging milk powder, a powder receiving chamber for receiving a feeding bottle is formed below the powder outlet, and a control structure for controlling the powder discharge from the powder outlet is provided in the housing. The control structure comprises a blocking plate rotated below the powder outlet, and a drive assembly for driving the blocking plate to rotate, and the blocking plate has a powder discharging state and a powder blocking state in which it remains closed below the powder outlet. When the blocking plate is in the powder discharging state, the drive assembly abuts the blocking plate to rotate the blocking plate and move the blocking plate away from the powder outlet. When the blocking plate is in the powder blocking state, the drive assembly moves away from the blocking plate, and the blocking plate abuts below the powder outlet. The powder feeding structure includes a powder storage bucket, a paddle group rotated in the powder storage bucket, and a rotating unit that drives the paddle group to rotate. The paddle group includes a first paddle connected to the output end of the rotating unit, and a second paddle clamped on the first paddle. The powder outlet is formed at the bottom of the powder storage bucket. The first paddle is provided with a plurality of powder outlet grooves arranged at equal intervals. The powder outlet grooves are connected to the powder outlet, and the second paddle is provided with a first scraper arranged vertically downward and a second scraper arranged vertically upward. The second scraper is in contact with the inner wall of the powder storage bucket. Through the above improvements, the rotating unit can drive the first paddle and the second paddle to rotate. The first scraper on the second paddle can scrape the milk powder into the powder outlet groove of the first paddle, and the second scraper on the second paddle can scrape the milk powder on the inner wall of the powder storage bucket. As the first paddle rotates, the powder outlet groove on the first paddle will overlap with the powder outlet, causing the milk powder in the powder outlet groove to fall into the powder outlet, thereby realizing automatic conveying of the milk powder.

[0004] In the technical solution of the aforementioned patent document, a paddle scrapes milk powder into the powder outlet. When the powder outlet rotates through the powder outlet to the powder outlet, the milk powder falls into the outlet, achieving automatic powder shedding. The fallen milk powder is then guided by a powder guide shield and discharged into the feeding bottle. This can cause the powder guide shield to come into contact with and absorb the milk powder. If not cleaned promptly, the powder will deteriorate, contaminating the next batch of milk powder. Furthermore, the barrier plate that seals the powder outlet is still in direct contact with the outside world, posing a risk of insects such as cockroaches and ants crawling onto the barrier plate, causing contamination. Furthermore, during actual use, the barrier plate may also absorb a small amount of milk powder, which deteriorates upon contact with air. When the barrier plate is opened or closed, the milk powder adsorbed on the barrier plate can be shaken off into the feeding bottle. Summary of the Invention

[0037] In one embodiment of the powder dispensing machine structure of the present invention, please refer to Figures 1 to 7The powder dispensing machine structure of the present embodiment is used for storing milk powder and outputting milk powder in a quantitative manner, which is convenient for the storage and use of milk powder, and can control the amount of milk powder for scientific feeding. Specifically, the powder dispensing machine of the present embodiment includes a barrel 100, a sealing cover 200, a conveying pipe 300, a power assembly 400 and a sealing stop cover 500. A cavity 101 is provided in the barrel 100, and the cavity 101 is used to store milk powder. Specifically, the milk powder can be poured into the cavity 101 after unpacking, or the canned milk powder can be opened and directly placed into the cavity 101. A protrusion 110 is also extended outward from the upper end of the outer side of the barrel 100, and a mounting cavity 111 is provided in the protrusion 110, and a powder dropping through hole 112 is provided at the bottom of the mounting cavity 111. The delivery pipe 300 includes an input end 301 and an output end 302. The input end 301 of the delivery pipe 300 extends into the cavity 101 through the side wall of the barrel 100, and the output end 302 is located in the installation cavity 111. The bottom side of the output end 302 is provided with an output port 303 located at the upper end of the powder dropping through hole 112. The power assembly 400 is connected to the delivery pipe 300 and is used to lift the milk powder in the cavity 101 to be output from the delivery pipe 300. Among them, the power assembly 400 can be a powder pump or an elevator structure. The sealing cover 500 is connected to the bottom side of the protrusion 110 and is used to open and seal the powder dropping through hole 112. Specifically, the sealing cover 500 can be electrically opened and closed, or manually opened and sealed. The sealing cover 200 is provided at the upper end of the barrel 100 and is used to seal the barrel 100.

[0038] Specifically, in this embodiment, milk powder can be loaded into the cavity 101, with the input end 301 of the delivery tube 300 extending into the cavity. To access the milk powder, the sealing baffle 500 is first opened downward. The power assembly 400 provides power to the milk powder within the cavity 101, allowing the milk powder to be transported from the input end 301 of the delivery tube 300 to the output end 302 and then output from the output port 303 to the bottom feeding bottle. After the powder is discharged, the sealing baffle 500 can be used to cover and seal the powder dropout hole 112, preventing the output port 303 from being exposed to the air and thus preventing the external environment from causing secondary contamination of the output port 303. Because the sealing baffle 500 covers the bottom side of the protrusion 110 and does not contact the output port 303, secondary contamination of the output port 303 by the sealing baffle 500 is avoided, and milk powder is also prevented from sticking to the sealing baffle 500. The milk powder is sealed in the sealed space enclosed by the sealing cap 200 and the shell 100, preventing the milk powder from coming into contact with air and achieving moisture-proof effect. The milk powder is outputted by the delivery tube 300, and during the powder output process, the milk powder in the cavity 101 can also be prevented from coming into contact with the outside air, further providing a sealed isolation for the milk powder.

[0039] Further, refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 6The outlet 303 is also provided with a downwardly extending guide nozzle 304, which extends toward the powder dropout hole 112 and does not extend below the bottom of the hole. A guide cone 305 is provided within the guide nozzle 304. In this embodiment, milk powder is discharged from the outlet 303 and enters the guide cone 305, from which it then falls downward into the feeding bottle. The guide cone 305 collects and guides the milk powder, preventing it from dispersing and falling onto the mounting cavity 111 or the sidewalls of the powder dropout hole 112.

[0040] Further, refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 6 The power assembly 400 includes a flexible shaft 410 and a motor 420. The flexible shaft 410 includes a connecting end 411 and a free end 412. The flexible shaft 410 penetrates the delivery tube 300, and the free end 412 extends from the input end 301 of the delivery tube 300. The connecting end 411 rotatably passes through the output end 302. The flexible shaft 410 is provided with a spiral groove 413. One end of the spiral groove 413 extends to the free end 412, and the other end extends to the output port 303. The spiral groove 413 forms a spiral channel with the wall of the delivery tube 300. The motor 420 is disposed in the mounting cavity 111 and connected to the connecting end 411, and is used to drive the flexible shaft 410 to rotate. Specifically, a support seat 113 is disposed in the mounting cavity 111. The support seat 113 is provided with a rotating connector 114. The rotating connector 114 is rotatably connected to the support seat 113. The connecting end 411 of the flexible shaft 410 is connected to the rotating connector 114. The motor 420 is connected to the rotating connector 114 by a transmission belt. In this embodiment, the free end 412 of the flexible shaft 410 extends from the input end 301 of the delivery tube 300, and the milk powder is filled into the spiral groove 413 extending from the delivery tube 300. The motor 420 drives the flexible shaft 410 to rotate, and the milk powder enters the delivery tube 300 along the spiral groove 413 and is transported toward the output end 302. When the milk powder reaches the output port 303, it falls downward from the output port 303 into the feeding bottle.

[0041] Going further, refer to Figures 2 to 4 A support platform 120 extends from the lower outer end of the cylindrical shell 100 and is located at the bottom of the protrusion 110. A weighing device 130 is also mounted on the support platform 120. Preferably, the weighing device 130 includes a weight sensor. A feeding bottle can be placed on the weighing device 130, which then weighs the milk powder, accurately controlling the amount of milk powder.

[0042] Furthermore, in order to more accurately control the amount of milk powder discharged, the motor 420 can be used to drive the flexible shaft 410 to rotate rapidly so that the milk powder is quickly discharged into the bottle. When the weighing device 130 detects that the milk powder is close to the set weight, the motor 420 starts to reduce the speed and rotate the flexible shaft 410 slowly, thereby controlling the slow output of the milk powder and avoiding excessive milk powder being discharged, thereby achieving accurate control of the amount of milk powder discharged.

[0043] Further, refer to Figures 4 to 6 and Figure 9 The output end 302 of the delivery tube 300 is further provided with a mounting opening 306, which is located on one side of the output port 303, specifically above the output port 303. A powder scraper 310 is disposed within the mounting opening 306. The powder scraper 310 includes a scraper plate 311 that extends into the spiral groove 413. In this embodiment, when milk powder is transported along the spiral groove 413 to the output end 302, the scraper plate 311 cooperates with the spiral groove 413 to scrape the milk powder from the spiral groove 413, facilitating its downward flow and preventing the milk powder from continuing to be transported toward the connection end 411, thereby preventing the milk powder from entering the mounting cavity 111.

[0044] Furthermore, refer to Figure 3 、 Figure 5 and Figure 9 In order to make the powder scraping member 310 more stable, a fixing sleeve 307 is provided on the top side of the conveying pipe 300 , and a pin 312 extending into the fixing sleeve 307 is provided on one side of the powder scraping member 310 .

[0045] Further, refer to Figure 2 、 Figure 4 and Figure 8 The free end 412 of the flexible shaft 410 is also provided with a radially extending stirring member 430. The stirring member 430 rotates with the flexible shaft 410, and can stir the milk powder at the bottom of the cavity 101 to fill it into the spiral groove 413. Ensure that the milk powder is transported normally. The stirring member 430 includes a connecting member 431, a sleeve 432 and a stirring blade 433. The connecting member 431 is provided with a snap-in hole 434, and the free end 412 of the flexible shaft 410 is snap-in to the snap-in hole 434. The sleeve 432 is sleeved on the flexible shaft 410 and is located at the bottom end of the conveying pipe 300. The stirring blade 433 connects the connecting member 431 and the sleeve 432, so that a feeding space is formed between the sleeve 432 and the connecting member 431. Specifically, when the stirring member 430 rotates along with the flexible shaft 410 , the stirring blades 433 stir the milk powder at the bottom of the cavity 101 , so that the milk powder is filled into the feeding space and then into the spiral groove 413 .

[0046] Furthermore, refer to Figure 2 and Figure 4The bottom end of the cavity 101 is provided with an inwardly contracted stirring chamber 102, and the outer ring of the stirring blade 433 is provided with a support ring 435 rotatably arranged in the stirring chamber 102. The stirring member 430 is positioned in the stirring chamber 102, which can avoid the problem of free shaking of the free end 412.

[0047] Further, refer to Figure 3 The powder dispensing machine structure also includes an air pump 600, which is connected to the cavity 101 and is used to exhaust air from the cavity 101. The air pump 600 is located within the mounting cavity 111. In this embodiment, the milk powder is stored within the cavity 101. The air pump 600 exhausts the air within the cavity 101, creating a vacuum state within the cavity 101. This further prevents contamination of the milk powder by moisture and other substances in the air, thereby increasing the storage time and effectiveness of the milk powder. Furthermore, after the powder is discharged, the air pump 600 can be used to evacuate the milk powder in the delivery tube 300, allowing the milk powder to return to the cavity 101 under the action of negative pressure. This prevents the milk powder from clumping within the delivery tube 300. Furthermore, while the air pump 600 is evacuating the milk powder in the delivery tube 300 and returning it to the cavity 110, the motor 420 can also drive the flexible shaft 410 to reverse, transporting the milk powder downward in the opposite direction, causing the milk powder to reflux and preventing it from clumping within the spiral channel. After the milk powder flows back, the sealing baffle 500 seals the powder falling hole 112, and the vacuum pump 600 completes the vacuuming of the cavity 111.

[0048] Further, refer to Figure 1 and Figure 2 The sealing cover 200 is also provided with a pressure relief port 201 and a sealing member 202 for sealing the pressure relief port 201. When the sealing cover 200 is opened, the sealing member 202 is opened first to release the pressure, and then the sealing cover 200 is opened conveniently.

[0049] Furthermore, refer to Figure 2 The sealing cover 200 includes a middle frame 210 and a top cover 220. The middle frame 210 is located at the upper end of the cylindrical shell 100. A covering portion 211 extends from one side of the middle frame 210 to cover the mounting cavity 111. The covering portion 211 has a through hole 212, through which the output end 302 of the delivery tube 300 passes. The middle frame 210 is provided with a sealing step, and the top cover 220 is located within the middle frame 210 and supported on the sealing step.

[0050] Further, refer to Figure 2 and Figure 4The cartridge case 100 includes an outer shell 140, an inner shell 150, and an inner liner 160. The inner shell 150 is disposed within the outer shell 140, with a protrusion 110 disposed on the upper end of the inner shell 150. The inner liner is removably disposed within the inner shell 150. A sealing cap 500 covers the opening of the inner shell 150. The cavity 101 is disposed within the inner shell 160. Preferably, the bottom end of the inner shell 160 contracts inward to form a stirring chamber 102. A support plate 161 is disposed at the bottom of the inner shell 160, supporting the bottom of the inner shell 150 and increasing the stability of the inner shell 160 within the inner shell 150.

[0051] Further, refer to Figure 7 The sealing cover 500 includes a cover plate 510 and a driving member 520. Two connecting rods 511 are provided on the top side of the cover plate 510. One end of the connecting rod 511 passes through the powder drop hole 112 and is rotatably mounted in the mounting cavity 111. The other end is connected to the cover plate 510. The driving member 520 is disposed in the mounting cavity 111 and connected to the connecting rod 511. Specifically, the driving member 520 is a driving motor.
