Description

Technical Field

[0001] The utility model relates to the technical field of milk shaker equipment, in particular to a milk shaker with a sealed anti-backflow air duct. Background Art

[0002] A milk shaker is a modern maternal and infant appliance used to mix milk powder with water to ensure that the baby gets enough nutrition. During the shaking process, the bottle is usually heated with hot air to ensure that the liquid temperature is acceptable to the baby. For example, the patent document with publication number CN219835521U describes a waterless milk shaker, which includes a milk bottle basket, a hot air component for blowing hot air to the milk bottle basket, and a rotating component for driving the milk bottle basket to rotate. The milk bottle basket is provided with a first opening at the bottom, and also includes a telescopic member that is telescopic along the axis of the first opening. The end of the telescopic member is provided with a temperature sensor for collecting the temperature inside the milk bottle basket. By providing the temperature sensor that directly extends into the bottom of the milk bottle basket, the temperature inside the milk bottle basket can be accurately collected, and it can be pressed against the bottom of the milk bottle to accurately detect the temperature of the milk bottle. In addition, the telescopic member can control the position of the temperature sensor. During the milk shaking process, that is, when the milk bottle is rotating, the temperature sensor is moved away from the milk bottle. When the milk bottle stops rotating, the temperature sensor is pressed against the bottom of the milk bottle to measure the temperature. This can not only accurately detect the temperature, but also ensure that there is no friction with the temperature sensor during the milk shaking process. The milk shaking movement is smooth and noiseless, which greatly increases the detection accuracy and service life of the temperature sensor.

[0003] However, in actual use, the bottles may fall over or leak liquid due to the violent vibrations caused by rotation. Such liquid can penetrate into the air duct through the gaps in the bottle basket, corrode electronic components such as the heating element, or cause a short circuit. Summary of the Invention

[0004] In view of the problems in the related art, the present invention proposes a milk shaker with a sealed anti-backflow air duct to avoid short circuit and corrosion of the heating element due to liquid leakage.

[0005] The utility model is achieved in this way:

[0006] and a tube connecting the discharging opening of the inlet and the outlet passages thereof. The tube connecting the discharging opening of the inlet and the outlet passages is connected with the tube connecting the discharging opening to the outlet passage. The tube connecting the discharging opening and the outlet passages are connected with the tube connecting the discharging opening to the outlet passage.

[0007] An air outlet is provided at the output end; the air outlet opens upward and is located directly below the air inlet and directly above the slope; the air outlet is larger than the air inlet.

[0008] The liquid generated / existing in the rotating barrel (such as liquid leaking from a baby bottle) flows from the air inlet, air outlet, and slope to the drainage hole in sequence; the water-retaining ribs prevent the liquid from contacting the heating unit to avoid short circuit.

[0009] The horizontal setting of the air duct helps to flatten the design of the milk shaker and improve the stability of the equipment when shaking milk.

[0010] As a further optimization of the above solution, the air outlet surface and the bottom outer surface of the rotary barrel only have gaps.

[0011] The air duct and the rotary drum are not connected to each other to avoid interfering with the rotation of the rotary drum; there are only gaps, air outlets and air inlets between the two, which can ensure that hot air is blown into the rotary drum as much as possible, reducing losses and noise.

[0012] As a further optimization of the above solution, the air duct is formed by assembling a separable upper shell and a lower shell.

[0013] As a further optimization of the above solution, a plurality of evenly distributed air inlet holes are provided at the bottom of the rotary barrel.

[0014] As a further optimization of the above solution, the multiple air inlet holes are evenly distributed along the circumference of the bottom edge of the rotary barrel; the air inlet holes are inclined at the edges close to the center of the rotary barrel; a reversing portion is provided above the air inlet holes; the reversing portion completely covers the air inlet holes and is only open on one side facing the center of the rotary barrel.

[0015] The reversing portion and the inclined surface cooperate with each other so that after the hot air enters the air inlet, it is discharged from the opening of the reversing portion in an obliquely upward direction toward the center of the rotating barrel, ultimately forming an oblique upward discharge to the feeding bottles. This allows the hot air to contact the feeding bottles as much as possible and slows down the loss of the hot air from the opening of the rotating barrel.

[0016] As a further optimization of the above solution, a control circuit board is provided in the milk shaker; the control circuit board is fixedly suspended in the air compared to the bottom of the shell; the heating unit, the exhaust unit, and the driving unit are respectively connected to the control circuit board by telecommunications.

[0017] Liquid flowing out of the drain hole may leak into the inside of the housing; the control circuit board is suspended in the air to avoid contact with leaking liquid.

[0018] 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;

[0019] 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;

[0020] 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.

[0021] As a further optimization of the above solution, a raised temperature measuring probe is provided at the center of the bottom of the rotating barrel; the bottom of the milk bottle and the temperature measuring probe are adapted to each other.

[0022] As a further optimization of the above solution, the temperature measuring probe is a retractable structure; when the feeding bottle is placed inside the rotating barrel, the temperature measuring probe is tightly fitted to the surface of the feeding bottle, and the temperature measuring probe partially retracts downward; when the feeding bottle and the rotating barrel are separated, the temperature measuring probe extends to its original position.

[0023] As a further optimization of the above solution, the center of the rotary barrel is provided with a movable groove running downward; a circle of first limiting protrusions is provided along the inner circumference of the movable groove;

[0024] The invention also includes a telescopic member and a compression spring; the upper portion of the telescopic member is a bullet-shaped structure with the tip facing upward, and the lower portion is a guide column; the upper portion of the telescopic member is provided with a circle of second limiting protrusions along the outer peripheral side surface; the interior of the telescopic member is a hollow structure that passes through the upper and lower ends; the temperature measuring probe is provided inside the telescopic member;

[0025] The telescopic member is arranged in the movable groove, and the second limiting protrusion is located below the first limiting protrusion; the compression spring is sleeved on the outer peripheral side of the guide column;

[0026] Under normal conditions, the first limiting protrusion and the second limiting protrusion abut against each other under the action of the compression spring; when the feeding bottle is placed inside the rotating barrel, the temperature measuring probe is tightly fitted to the surface of the feeding bottle under the action of the compression spring.

[0051] The rotating barrel 2 is adapted to the feeding bottle and is used to drive the feeding bottle to rotate and shake. Specifically, in this embodiment, a clamping member 3 is provided in the rotating barrel 2; the clamping member 3 is a cylindrical structure and fits tightly against the inner wall of the rotating barrel 2.

[0052] The inner side of the clamping member 3 is provided with a plurality of elastically resettable and circumferentially evenly distributed clamping arms 3-1, the upper ends of the clamping arms 3-1 are integrally connected to the main body of the clamping member 3; the clamping arms 3-1 are tilted toward the center of the main body of the clamping member 3; the lower ends of the clamping arms 3-1 are directed directly downward; the clamping arms 3-1 are directed obliquely downward; when the bottle is placed inside the rotating barrel 2; the lower ends of the plurality of clamping arms 3-1 jointly clamp and fix the bottle.

[0053] In this embodiment, a raised temperature measuring probe 4 that can be extended up and down is provided at the center of the bottom of the rotary barrel 2 .

[0054] Specifically, the center of the rotary barrel 2 is provided with a movable groove 2-1 extending downwardly therethrough; a circle of first limiting protrusions 2-2 is provided along the inner circumference of the movable groove 2-1;

[0057] Under normal conditions, the first limiting protrusion 2-2 and the second limiting protrusion 5-2 abut against each other under the action of the compression spring 6; when the bottle is placed inside the rotating barrel 2, the bottom of the bottle and the temperature measuring probe 4 fit together, and the temperature measuring probe 4 and the surface of the bottle are tightly fitted under the action of the compression spring 6. At this time, the temperature measuring probe 4 is in a partially downward retracted state.
