[0027] Embodiment 1

[0028] This embodiment provides a powder feeding structure for a powder brewing machine, which includes: a powder bin 100 for accommodating powder and a feeding assembly 200. An outlet 101 is formed on the powder bin 100. The feeding assembly 200 includes a metering plate 201 and a powder sweeping plate 202 rotatably arranged inside the powder bin 100. A feeding hole 2021 is formed on the powder sweeping plate 202. A powder storage grid 2011 capable of communicating with the powder in the powder bin 100 through the feeding hole 2021 is formed on the metering plate 201. The metering plate 201 and / or the powder sweeping plate 202 rotate relative to the powder bin 100 so that the feeding hole 2021 and the outlet 101 communicate with the powder storage grid 2011 at different times respectively.

[0029] Please refer to Figure 1 and Figure 3As shown, in this embodiment, the powder bin 100 is set as a cylindrical structure with an open upper end and a hollow interior for storing powder. Inside the powder bin 100, there are a metering plate 201 and a powder sweeping plate 202 for metering the powder. The powder sweeping plate 202 and the metering plate 201 are stacked in sequence at the bottom of the powder bin 100. The metering plate 201 is provided with powder storage cells 2011, and the powder storage cells 2011 are through holes penetrating the upper and lower surfaces of the metering plate 201. Since the lower surface of the metering plate 201 abuts against the bottom of the powder bin 100 and the upper surface abuts against the powder sweeping plate 202, and because the metering plate 201 has a certain thickness, the through holes on the metering plate 201 form powder storage cells 2011 with a certain storage space, and the powder storage cells 2011 can store powder. The powder sweeping plate 202 is arranged above the metering plate 201, and the powder sweeping plate 202 is provided with material distribution holes 2021. When the powder sweeping plate 202 rotates, the material distribution holes 2021 can be communicated with the powder storage cells 2011, and at this time, the powder in the powder bin 100 enters the powder storage cells 2011. When the powder sweeping plate 202 rotates further, it pushes the powder to fill the powder storage cells 2011 until the material distribution holes 2021 are misaligned with the powder storage cells 2011, and the powder storage cells 2011 are filled with a fixed amount of powder. At the bottom of the powder bin 100, there is a powder outlet 101, and the powder outlet 101 is located on the moving path of the powder storage cells 2011. When the metering plate 201 rotates to the powder outlet angle, the powder storage cells 2011 are communicated with the powder outlet 101, and the fixed amount of powder stored in the powder storage cells 2011 falls from the powder outlet 101 under the action of gravity and enters the external brewing machine. Since the material distribution holes 2021 and the powder outlet 101 are respectively communicated with the powder storage cells 2011 at different times, when the powder in the powder storage cells 2011 falls into the brewing machine from the powder outlet 101, the material distribution holes 2021 are not communicated with the powder storage cells 2011, preventing the powder in the powder bin 100 from entering the powder storage cells 2011 at this time and ensuring that the weight of the powder falling from the powder outlet 101 is basically the same each time. After the powder in the powder storage cells 2011 is discharged, the metering plate 201 and the powder sweeping plate 202 continue to rotate until the powder storage cells 2011 are misaligned with the powder outlet 101 and are communicated with the material distribution holes 2021. At this time, the powder is refilled into the powder storage cells 2011 and the above-mentioned powder discharging steps are repeated. During powder brewing, since the amount of powder in each powder storage cell 2011 is fixed, only by controlling the number of rotations of the metering plate 201 can the amount of powder falling from the powder outlet 101 be accurately controlled, thereby ensuring the concentration during brewing. During brewing, there is no need for the operator to manually take and weigh the powder, simplifying the brewing steps and improving the user experience.

[0030] Optionally, please refer to Figure 1As shown, in this embodiment, a plurality of powder storage grids 2011 of the same size are circumferentially spaced on the metering disk 201, and a plurality of powder distribution holes 2021 can be circumferentially spaced on the powder sweeping disk 202. When the metering disk 201 rotates one circle, the powder in multiple powder storage grids 2011 can fall into the brewing machine from the powder outlet 101, improving the powder feeding rate.

[0031] Optionally, in some embodiments of this embodiment, the powder feeding structure of the powder brewing machine further includes a driving assembly 300. The driving assembly 300 includes a driving motor 301, a first output shaft 302, and a speed reduction output mechanism 303. The powder sweeping disk 202 is connected to the output shaft of the driving motor 301 through the first output shaft 302, and the metering disk 201 is connected to the output shaft of the driving motor 301 through the speed reduction output mechanism 303, so that the rotation speed of the metering disk 201 is less than the rotation speed of the powder sweeping disk 202.

[0032] Please refer to Figure 1 and Figure 2 As shown, in this embodiment, the metering disk 201 and the powder sweeping disk 202 are driven by the driving motor 301 without manual operation. Moreover, the driving motor 301 can be electrically connected or signal-connected to the control device of the brewing machine to achieve intelligent control. Specifically, the output shaft of the driving motor 301 is in driving cooperation with the powder sweeping disk 202 through the first output shaft 302, and the output shaft of the driving motor 301 is in driving connection with the metering disk 201 through the speed reduction output mechanism 303. Under the action of the speed reduction output mechanism 303, there is a speed difference between the metering disk 201 and the powder sweeping disk 202, so as to realize the connection and dislocation of the powder storage grid 2011 and the powder distribution hole 2021.

[0033] Optionally, in some embodiments of this embodiment, the speed reduction output mechanism 303 includes a housing 3031, a rotating frame 3032, and a second output shaft 3033. The rotating frame 3032 is rotatably arranged inside the housing 3031. A first gear 3034 is fixedly arranged on the first output shaft 302. A second gear 3035 is rotatably arranged on the rotating frame 3032. A toothed ring 3036 is arranged on the inner side wall of the housing 3031. The second gear 3035 meshes with the first gear 3034 and the toothed ring 3036 respectively. The second output shaft 3033 is arranged on the rotating frame 3032 and is connected to the metering disk 201.

[0034] Please refer to Figure 1 and Figure 2As shown, in this embodiment, both the drive motor 301 and the reduction output mechanism 303 are arranged outside the powder bin 100, reducing the number of parts inside the powder bin 100, facilitating the weighing of the powder, and also facilitating the cleaning of the powder bin 100, avoiding the deterioration of the powder residue during the cleaning of the powder bin 100 and endangering the health of infants. The reduction output mechanism 303 includes a housing 3031, a rotating frame 3032, and a second gear 3035 arranged on the rotating frame 3032. A first gear 3034 is arranged on the first output shaft 302. The first gear 3034, the second gear 3035, the rotating frame 3032, and the toothed ring 3036 on the housing 3031 form a planetary gear reduction mechanism. The second output shaft 3033 is connected to the rotating frame 3032 and rotates synchronously with the rotating frame 3032. The rotating shaft of the drive motor 301 is connected to the powder sweeping frame through the first output shaft 302. When the drive motor 301 drives the first output shaft 302 to rotate, the first gear 3034 on the first output shaft 302 drives the second gear 3035 to rotate. The second gear 3035 meshes with the toothed ring 3036 on the housing 3031, driving the rotating frame 3032 to rotate and driving the metering disc 201 to rotate through the second output shaft 3033, so that there is a speed difference between the first output shaft 302 and the first output shaft 302, thereby achieving the effect of weighing the powder. It should be noted that in this embodiment, the number of powder storage cells 2011 and dispensing holes 2021 is not limited and can be any number such as one, two, three, four, etc., and the powder storage cells 2011 and the dispensing holes 2021 can be set to different numbers. Therefore, this embodiment does not limit the speed ratio of the first output shaft 302 and the second output shaft 3033. When manufacturing, the speed ratio of the first output shaft 302 and the second output shaft 3033 is set according to the number of powder storage cells 2011 and dispensing holes 2021, as long as the technical effect that the dispensing holes 2021 and the powder outlet 101 are respectively communicated with the powder storage cells 2011 at different times is satisfied.

[0035] Optionally, in some embodiments of this embodiment, the first output shaft 302 is detachably connected to the powder sweeping disc 202, and the metering disc 201 is detachably connected to the second output shaft 3033.

[0036] Please refer to Figure 1As shown, in this embodiment, the powder sweeping disk 202 is detachably connected to the first output shaft 302, and the metering disk 201 is detachably connected to the second output shaft 3033. The user can detach and replace different metering disks 201 or powder sweeping disks 202 according to needs. On the one hand, by replacing the metering disk 201 with different sizes of powder storage grids 2011, the powder output can be further controlled. It can be understood that the size of the powder storage grid 2011 determines the powder output of one unit, that is, the minimum output of the powder agent. When rotating the metering disk 201, the total powder output is adjusted by the number of output portions of the powder agent. Therefore, when it is necessary to adjust the powder dose of each unit, it can be achieved by replacing different metering disks 201, improving the use effect and practicability of the entire device. On the other hand, after removing the powder sweeping disk 202 and the metering disk 201, the powder bin 100 can be maximally exposed, facilitating the cleaning of the powder bin 100, as well as the cleaning and disinfection of the powder sweeping disk 202 and the metering disk 201, ensuring the safety of food, avoiding the expiration and deterioration of the remaining powder agent affecting the health of infants, and making the operation of cleaning the powder bin 100 more convenient and fast.

[0037] Optionally, please refer to Figure 2 As shown, in some embodiments of this embodiment, splines are provided on both the first output shaft 302 and the second output shaft 3033, and key grooves are correspondingly provided on the metering disk 201 and the powder sweeping disk 202. The powder sweeping disk 202 and the metering disk 201 are respectively clamped to the first output shaft 302 and the second output shaft 3033 through the key grooves, realizing detachable connection while ensuring that the powder sweeping disk 202 rotates synchronously with the first output shaft 302 and the metering disk 201 rotates synchronously with the second output shaft 3033.

[0038] Optionally, in some embodiments of this embodiment, a scraping strip 2022 is provided at the edge of the powder sweeping disk 202, and the scraping strip 2022 fits against the inner side wall of the powder bin 100.

[0039] Please refer to Figure 4 As shown, in this embodiment, a scraping strip 2022 is provided at the edge of the powder sweeping disk 202, and the scraping strip 2022 fits against the inner side wall of the powder bin 100. When the powder sweeping disk 202 rotates, the scraping strip 2022 can sweep down the powder adhering to the side wall of the powder bin 100, ensuring that the powder enters the powder storage grid 2011.

[0040] Optionally, in some embodiments of this embodiment, a feeding port is provided on the powder bin 100, and the feeding port is covered with a sealing cover 400.

[0041] Please refer to Figure 1As shown, in this embodiment, the upper end opening of the powder bin 100 forms a feeding port. The user puts the powder into the powder bin 100 from the feeding port, and the powder bin 100 can store the powder for multiple brews. At the same time, a sealing cover 400 is provided at the feeding port. The sealing cover 400 plays a role in sealing to prevent external foreign objects from entering the powder bin 100 and contaminating the powder, ensuring the safety of the powder.

[0042] Optionally, in some embodiments of this embodiment, a sealing ring is provided at the connection between the sealing cover 400 and the powder bin 100.

[0043] In this embodiment, the sealing ring can be made of soft materials such as rubber or silica gel. The sealing ring is provided on the sealing cover 400 to seal the gap between the sealing cover 400 and the powder bin 100. On the one hand, the sealing ring can prevent tiny impurities such as dust from entering the powder bin 100 and contaminating the powder. On the other hand, the sealing ring can prevent water vapor or liquid from entering the powder bin 100, ensuring the dryness of the powder. It can be understood that nutritional powder usually has good water absorption and is very easy to get damp. The damp powder is prone to caking, which is not convenient for weighing and controlling the powder output. Moreover, the damp powder is prone to spoilage, which may affect the health of infants.

[0044] Optionally, in some embodiments of this embodiment, a powder drainage strip 401 is provided on the side of the sealing cover 400 close to the powder bin 100.

[0045] Please refer to Figure 4. In this embodiment, the powder drainage strip 401 on the sealing cover 400 extends into the powder bin 100. When the powder sweeping disc 202 rotates, it will drive the powder in the powder bin 100 to move. Under the action of the powder drainage strip 401, the powder in the powder bin 100 can be dispersed, preventing the powder from caking or stacking on one side of the powder bin 100, enabling the powder to be smoothly dispersed and completely fill the entire powder bin 100 and the powder storage grid 2011, and avoiding insufficient powder output caused by the incomplete filling of the powder storage grid 2011, which affects the brewing concentration.

[0046] Optionally, in some embodiments of this embodiment, a powder scraping protrusion 2023 is provided on the side of the powder sweeping disc 202 away from the metering disc 201.

[0047] Please refer to Figure 4 As shown, in this embodiment, the powder scraping protrusion 2023 cooperates with the powder drainage strip 401 on the sealing cover 400 and the scraping strip 2022 at the edge of the powder sweeping disc 202 to evenly disperse the powder in the powder bin 100.
