DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-Figure 8 A powder discharging mechanism of a milk mixer comprises a powder storage box 4 for storing milk powder, the interior of the powder storage box 4 is provided with a powder discharging dial 5 which can rotate relative to the powder storage box 4. Specifically, a motor frame 2 is installed below the powder storage box 4, a stirring motor 1 is installed inside the motor frame 2, a connecting shaft 3 is installed on the output shaft of the stirring motor 1, and the connecting shaft 3 is connected to the powder discharging dial 5 located inside the powder storage box 4. After the stirring motor 1 is started, it can drive the connecting shaft 3 to rotate, and then drive the powder discharging dial 5 to rotate inside the powder storage box 4.

[0033] A plurality of elastic scrapers 6 are installed in the circumferential direction of the powder discharge dial 5. The elastic scrapers are made of silicone. The elastic scrapers 6 can move the milk powder in the powder storage box 4 toward the powder discharge channel 401 of the powder storage box 4, and restore the milk powder to its original state after passing through the powder discharge channel 401 by utilizing the elastic deformation of the elastic scrapers 6. A powder beating fork 8 that can rotate relative to the powder discharge dial 5 is provided on the powder discharge dial 5. The lower surface of the powder beating fork 8 is in contact with the upper surface of the powder discharge dial 5, so that the milk powder can be stirred when the powder discharge dial 5 rotates to prevent local accumulation of the milk powder.

[0034] Specifically, the powder discharging dial 5 includes an inner disk 502 and an outer ring 501 which are arranged concentrically, and an annular accommodating cavity 506 is formed between the inner disk 502 and the outer ring 501. A plurality of lintels 504 for connecting the inner disk 502 and the outer ring 501 are provided above the accommodating cavity 506. The upper surface of the inner disk 502 is a raised conical structure. When the powder discharging dial 5 rotates, the milk powder can move toward the accommodating cavity 506. Figure 6As shown, since the inner plate 502 is a conical structure, the milk powder can move around under the action of its own gravity, thereby entering the accommodating chamber 506. Since the powder discharging dial 5 can rotate during operation, it is further convenient for the milk powder to move around.

[0035] Specifically, a mounting hole 503 is provided at the center of the lintel 504, and the elastic scraper 6 is installed in the mounting hole 503 and extends to the bottom of the accommodating cavity 506. The plurality of elastic scrapers 6 evenly divide the accommodating cavity 506 into independent spaces, so as to move the milk powder placed in the accommodating cavity 506 toward the powder outlet channel 401 of the powder storage box 4. Figure 6 As shown, in this example, there are six lintels 504, that is, the number of elastic scrapers 6 is also six. The six elastic scrapers 6 divide the annular accommodating chamber 506 into six independent and uniform spaces. When the powder discharge dial 5 rotates, the elastic scraper 6 can drive the milk powder in the space on one side to move. This arrangement is, on the one hand, to gradually push the milk powder to the position of the powder discharge channel 401 for easy discharge, and on the other hand, to avoid the problem of tangling caused by excessive concentration of milk powder in the annular accommodating chamber 506, thereby improving the smoothness of discharge.

[0036] Specifically, a first center rod 505 extending upward is provided at the center of the powder discharge dial 5, the powder fork 8 is sleeved on the first center rod 505, a box cover 9 is installed above the powder storage box 4, and a second center rod 901 extending downward is provided at the center of the box cover 9, and a limiting mechanism for limiting the powder fork 8 is provided between the powder fork 8 and the second center rod 901. The box cover 9 is installed on the powder storage box 4 in a snap-fit ​​manner, and is in a relatively static state with the powder storage box 4 when in use.

[0037] Specifically, the limiting mechanism includes a first protrusion 803 arranged at the upper end of the powder fork 8, and also includes a second protrusion 902 arranged at the lower end of the second center rod 901. After the box cover 9 is assembled on the powder storage box 4, the second center rod 901 can be sleeved on the first center rod 505, and the second protrusion 902 of the second center rod 901 and the first protrusion 803 on the powder fork 8 can be staggered in the circumferential direction. The powder fork 8 is a three-pronged structure, having an inclined rod 801 matching the conical structure of the inner disk 502, and a horizontal rod 802 connected to the end of the inclined rod 801, as shown in FIG. Figure 7-8As shown, two first protrusions 803 are provided at the end of the powder mixing fork 8, and two second protrusions 902 are also provided at the end of the second center rod 901 of the box cover 9. During assembly, the first protrusion 803 is located between the two second protrusions 902. Since the box cover 9 is in a stationary state, when the first protrusion 803 contacts the second protrusion 902, the powder mixing fork 8 can be prevented from rotating together with the powder discharging dial 5, so that the powder mixing fork 8 and the powder discharging dial 5 have a relative rotating working state, and then the powder mixing fork 8 can be used to stir the milk powder to avoid the accumulation and tangling of the milk powder inside the powder storage box 4.

[0038] Specifically, a sealing ring 7 is installed at the connection between the powder mixing fork 8 and the powder discharging dial 5 to prevent milk powder from entering the position between the powder mixing fork 8 and the powder discharging dial 5.

[0039] Specifically, a sealing structure is provided on the powder outlet channel 401 to prevent water vapor from entering the powder storage box 4. More specifically, as shown in FIG. Figure 4-5 As shown, the sealing structure is a silicone baffle 402 installed on the powder outlet channel 401. When the milk powder moves horizontally to the powder outlet channel 401, the silicone baffle 402 can open the entrance of the powder outlet channel 401 under the force of the milk powder, so that the milk powder can be discharged downward from the powder outlet channel 401. When there is no force, the silicone baffle 402 can close the entrance of the powder outlet channel 401 to prevent water vapor from entering the powder storage box 4 from the position of the powder outlet channel 401, thereby effectively avoiding the occurrence of milk powder agglomeration problems.

[0040] In this powder discharging mechanism of the milk mixer, the milk powder is loaded into the powder storage box 4. When the powder is discharged, the connecting shaft 3 and the powder discharging dial 5 are driven by the stirring motor 1 to rotate. During the rotation of the powder discharging dial 5, the milk powder can move toward the accommodating chamber 506 of the powder discharging dial 5, and under the action of the elastic scraper 6, the milk powder is gradually pushed to the powder discharging channel 401, and finally the milk powder is discharged outward from the powder discharging channel 401. During this process, the powder mixing fork 8 and the powder discharging dial 5 are in a relatively rotating working state, and the powder mixing fork 8 can be used to stir the milk powder in the powder storage box 4 to avoid the milk powder from tangling and local accumulation in the powder storage box 4; after the powder discharging work is completed, the blocking piece 402 located at the powder discharging channel 401 can block the entrance of the powder discharging channel 401, thereby preventing the milk powder from being discharged downward on the one hand, and preventing the water vapor from entering the powder storage box 4 to cause the milk powder to be damp on the other hand.

[0041] 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, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
