[0037] According to a milk bottle lifting mechanism provided by an embodiment of the present application, please refer to Figures 1 to 5 , the milk bottle lifting mechanism 100 includes a milk bottle holder 150, a groove cam assembly 110 and a drive motor assembly 130 provided on a base 140. The groove cam assembly 110 is provided below the milk bottle holder 150. The groove cam assembly 110 includes a cylindrical cam 111 and a driven lifting cylinder 112 sleeved with each other. Transmission teeth forming a driven gear 1111 are provided on the surface of the cylindrical cam 111. The drive motor assembly 130 is meshed with the driven gear 1111 through an axially connected driving gear 131. The groove cam assembly 110 is a mechanical part that converts rotational motion into linear or other forms of motion. The groove on the groove cam assembly 110 is connected to the driven lifting cylinder 112. The drive motor assembly 130 drives the driving gear 131 to drive the driven gear 1111 to rotate, so that when the cylindrical cam 111 rotates, it drives the driven lifting cylinder 112 to rise or fall. By converting the rotational motion of the cylindrical cam 111 into the linear motion of the driven lifting cylinder 112 in the height direction, the function of lifting the milk bottle in the milk bottle holder 150 is realized. When the milk bottle lifting mechanism 100 is arranged below the powder outlet of the milk powder machine 1, milk bottles at different heights can rise to the powder outlet, preventing milk powder from spilling. The drive motor assembly 230 is arranged outside the cylindrical cam 111 through meshing connection, making the structure compact and occupying a small space.

[0038] In some possible embodiments, a motor mounting bracket 142 having a height equivalent to that of the driving gear 131 is provided on the base 140. The output shaft of the driving motor 132 is mounted downward on the upper side of the motor mounting bracket 142, and the driving gear 131 is horizontally mounted on the lower side of the motor mounting bracket 142 and axially connected to the output shaft. As Figure 4 shown in, the motor mounting bracket 142 is configured as a suspended plate structure, and the driving gear 131 is fixedly rotatably connected to the base 140, enhancing the stability of the rotational drive and making the structure of the driving motor assembly 130 more compact. Correspondingly, the driven gear 1111 is disposed at the bottom end of the cylindrical cam 111. The transmission radius of the driving gear 131 is equivalent to the radius of the driving motor 132, making the structure more compact.

[0039] In some possible embodiments, the driving gear 131 is a complete gear structure, and the driven gear 1111 is an incomplete structure. Among them, the transmission radius of the driving gear 131 is equivalent to the radius of the driving motor 132. Since the lifting height converted by the groove cam assembly 110 is related to the circumference of the rotation of the cylindrical cam 111, that is, the arc length of the rotation of the driven gear 1111. In the embodiments of the present application, the transmission radius of the milk bottle lifting mechanism 100 sleeved outside the milk bottle is relatively large compared to the size of the milk bottle and the height to be raised. Therefore, in order to save materials and facilitate production, the driven gear 1111 is provided as a section of driven rack along the circumferential direction of the outer side wall of the cylindrical cam 111, as Figure 5 shown in, an arc-shaped flange 1112 is further provided on the side wall surface of the cylindrical cam 111. The arc-shaped flange 1112 and the driven gear 1111 with an incomplete gear structure are connected end to end to form a ring shape. The arc-shaped flange 1112 protrudes in the horizontal direction relative to the side wall of the cylindrical cam 111, and the height of the protrusion of the arc-shaped flange 1112 should not be less than the tooth height of the driven gear 1111, preventing the driven gear 1111 from contacting the housing and playing a protective role.

[0040] In some possible embodiments, the surface of the cylindrical cam 111 is provided with multiple curved grooves 1113. The multiple curved grooves 1113 are symmetrically distributed along the axis of the cylindrical cam 111. At least one roller 1121 extending into the curved groove 1113 is provided on the surface of the driven lifting cylinder 112. The curved groove 1113 extends upward along the circumferential direction of the cylindrical cam 111. The multiple symmetric curved grooves 1113 can balance the force, making the transmission of the milk bottle lifting mechanism 100 more stable. The roller 1121 can reduce the frictional force when moving in the curved groove 1113, improve the transmission efficiency, and reduce the power consumption of the motor. The roller 1121 is arranged near the bottom end of the curved groove 1113, which can increase the maximum height of the driven lifting cylinder 112 for lifting and lowering movements, so that the milk bottle lifting mechanism 100 can adapt to more milk bottles of different sizes. The arc length of the driven gear 1111 of the incomplete gear structure is not less than the length of the positive projection of a single curved groove 1113 on the horizontal plane. During the operation of the milk bottle lifting mechanism 100, the horizontal distance that the roller 1121 moves along the curved groove 1113 is equal to the arc length of the rotation of the driven gear 1111. Therefore, in order to improve the utilization rate of the curved groove 1113, the arc length of the driven gear 1111 should not be less than the length of the positive projection of the curved groove 1113 on the horizontal plane.

[0041] In some possible embodiments, the milk bottle lifting mechanism 100 further includes a guiding portion connected to the driven lifting cylinder 112. In some possible embodiments, the milk bottle lifting mechanism 100 further includes a protective sleeve 160 extending upward from the outer edge of the base 140 to above the cylindrical cam 111. The guiding portion includes at least one rib 1122 provided on the outer surface of the driven lifting cylinder 112 along the height direction and at least one pair of guide rails 1411 provided on the guide rail mounting bracket 141. The rib 1122 can be slidably inserted into the guide rail 1411 in the up and down direction. As Figure 5 shown, both the guide rail 1411 and the rib 1122 are arranged along the height direction, which are used to limit the lateral movement of the driven lifting cylinder 112 and enable it to lift and lower smoothly along the guide rail 1411. In order to improve the strength of the guide rail 1411, the guide rail mounting bracket 141 includes at least one guide rail mounting plate 1412 extending upward from the base 140 and a guide rail fixing ring 1413 provided at the top end of the at least one guide rail mounting plate 1412. And the guide rail 1411 can be arranged between the side walls of the cylindrical cam 111 and the driven lifting cylinder 112, making the structure compact. The guide rail mounting plate 1412 can improve the strength of the guide rail 1411. When multiple guide rails 1411 are provided for balanced guiding, multiple guide rail mounting plates 1412 are also correspondingly provided. The guide rail fixing ring 1413 can prevent the multiple guide rails 1411 from shaking and improve the stability of the guiding.

[0042] The embodiment of the present application further provides a milk shaking device 1000, which includes the milk bottle lifting mechanism 100 described in any one of the above. The milk shaking device 1000 can drive the milk bottle 170 in the milk bottle holder 150 to rotate forward or backward to fully mix and shake the milk powder and hot water in the milk bottle.

[0043] The embodiment of the present application further provides a milk powder dispenser 1, which includes the milk bottle lifting mechanism 100 or the milk shaking device 1000 described in any one of the above.
