Description

Technical Field

[0001] The utility model relates to the technical field of milk shaker equipment, in particular to a stepped air duct structure with a high speed increase and a milk shaker. Background Art

[0002] A milk shaker is a modern maternal and infant electrical appliance used to mix milk powder with water to ensure that the baby can get enough nutrition. During the milk shaking process, the bottle is usually heated to ensure that the temperature of the liquid is acceptable to the baby. For example, the patent document with the announcement number CN221769809U describes a milk warming and shaking machine, which includes a milk bottle basket, a hot air component that blows hot air to the milk bottle basket, and a rotating component that drives the milk bottle basket to rotate. It also includes a temperature measuring unit and a lifting component. The lifting component includes a lifting shaft connected to the temperature measuring unit and a lifting gear that drives the lifting shaft to move relative to the milk bottle basket. In this solution, the flow path of the hot air is not optimized and controlled. The generated hot air blows directly into the entire inner cavity, and cannot be blown into the milk bottle in a targeted manner. On the one hand, the overall wind noise of the equipment is relatively large. On the other hand, the air volume and pressure directly blown onto the milk bottle are relatively small, resulting in poor heating effect and temperature maintenance effect on the milk bottle. Summary of the Invention

[0003] In response to the problems in the related art, the utility model proposes a stepped air duct structure with a speed increase and a milk shaker, which can effectively increase the wind speed and wind pressure of the hot air, enhance the heating effect, and reduce noise.

[0004] The utility model is achieved in that:

[0005] A stepped air duct structure with a high speed is applied to a milk shaker, the milk shaker comprising a rotating barrel and the air duct; the rotating barrel is provided with an air inlet; an air extraction unit and a heating unit are provided in the air duct; the air extraction unit is used to extract air from the external environment; the heating unit is used to heat the air to form hot air;

[0006] The air duct includes multiple segments connected in sequence, namely the first segment, the second segment, the third segment and the fourth segment; the first segment and the third segment are both horizontally oriented; the position of the first segment is higher than that of the third segment; the second segment is obliquely arranged; the exhaust unit is arranged at the first segment; the heating unit is arranged downstream of the exhaust unit; the air duct has an air outlet, which is arranged on the fourth segment and faces at least one of the air inlet holes; the air outlet surface and the bottom outer surface of the rotary barrel only have a gap.

[0007] By optimizing the design of the air duct, the generated hot air can flow out from the same air outlet, which can not only increase the wind pressure and speed, but also ensure that most of the hot air is blown to the bottles in the rotating barrel; on the other hand, the second section serves as an inclined pipe section, acting as an "oblique pipe", which can effectively increase the flow rate of the fluid in the pipe and enhance the heat transfer efficiency; the hot air has a unified flow direction to avoid being blown to other components, effectively reducing noise.

[0008] As a further optimization of the above solution, the diameter of the pipe from the input end to the output end of the second segment gradually decreases.

[0009] The flow rate of the fluid remains unchanged, and when the pipe diameter is reduced, the flow velocity increases.

[0010] As a further optimization of the above solution, the exhaust unit is a fan with axial air intake and circumferential air outlet; the axial direction of the exhaust unit is vertical; and the wind generated by the fan is output in a horizontal direction.

[0012] As a further optimization of the above solution, the air duct is formed by assembling a separable upper shell and a lower shell; and the heating unit is arranged in the third section.

[0013] The upper and lower detachable shell design facilitates the assembly of the air duct and internal electronic components, as well as subsequent disassembly and maintenance.

[0014] The present invention also provides a milk shaker, comprising a shell with an opening at the bottom thereof; a rotating barrel is mounted on the upper surface of the shell, with the opening of the rotating barrel facing upward; the rotating barrel is adapted to fit a milk bottle and is used to drive the milk bottle to rotate and shake; the utility model also comprises a driving unit, the driving unit being transmission-connected to the rotating barrel; and a stepped air duct structure for increasing speed as described above is provided inside the shell.

[0015] As a further optimization of the above solution, a raised temperature sensing probe is provided at the center of the bottom of the rotating barrel; the bottom of the milk bottle and the temperature sensing probe are adapted to each other.

[0016] As a further optimization of the above solution, the temperature sensing probe is a retractable structure; when the feeding bottle is placed inside the rotating barrel, the temperature sensing probe is tightly fitted to the surface of the feeding bottle, and the temperature sensing probe partially retracts downward; when the feeding bottle and the rotating barrel are separated, the temperature sensing probe extends to its original position.

[0017] As a further optimization of the above solution, the center of the rotary barrel is provided with a telescopic groove running downward; a circle of first limiting ribs is provided along the inner circumference of the telescopic groove;

[0021] As a further optimization of the above solution, a clamping member is provided in the rotating barrel; the clamping member body is a cylindrical or barrel-shaped structure, and is tightly fitted with the inner wall of the rotating barrel;

[0022] The inner side of the clamping member is provided with a plurality of elastically resettable clamping arms evenly distributed around the circumference, the upper ends of the clamping arms being integrally connected to the clamping member body; the clamping arms being tilted toward the center of the clamping member body; the lower ends of the clamping arms being directed directly downward; and the clamping arms being directed obliquely downward;

[0023] When the feeding bottle is placed inside the rotating barrel, the lower ends of the plurality of clamping arms jointly clamp and fix the feeding bottle.

[0024] The beneficial effects are as follows:

[0025] The utility model provides a stepped air duct structure and a milk shaker with a high speed. By optimizing the design of the air duct, the generated hot air is uniformly discharged from the same air outlet, which can not only increase the wind pressure and wind speed, but also ensure that most of the hot air is blown to the milk bottles in the rotating barrel; on the other hand, the second section serves as an inclined pipe section, plays the role of an "oblique pipe", and can effectively increase the flow rate of the fluid in the pipe and increase the heat transfer efficiency; the hot air has a unified flow direction, which avoids being blown to other components in a disorderly manner, and effectively reduces noise.
