Description

A low-resistance, precision powder pushing mechanism with a funnel-shaped opening Technical Field

[0001] This utility model relates to the field of milk maker technology, and in particular to a low-resistance, precise powder-pushing mechanism with a funnel-shaped opening. Background Technology

[0002] A formula maker is a mother and baby device that automatically adds and mixes milk powder and water in a certain ratio to make milk liquid. The existing milk powder adding mechanism has a powder leakage hole and a drive component that can seal the powder leakage hole at the bottom of the milk powder compartment. The disadvantage of this structure is that the milk powder is not easy to fall out of the powder leakage hole due to the accumulation of milk powder. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the main purpose of this utility model is to provide a low-resistance, precise powder pushing mechanism with a funnel-shaped opening that can smoothly convey milk powder with low resistance.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a low-resistance precision powder pushing mechanism with a flared mouth, comprising a powder storage bin, a powder pushing and feeding screw disposed at the bottom of the powder storage bin, one end of the powder pushing and feeding screw being driven to rotate by a drive component disposed outside the powder storage bin, the powder storage bin including a powder outlet channel into which the powder pushing and feeding screw can be inserted, a powder outlet cover capable of supporting the powder pushing and feeding screw being snapped onto the end of the powder outlet channel, and a powder drop hole disposed at the bottom of the powder outlet cover.

[0005] Preferably, the drive assembly includes a motor, a first bevel gear fixedly connected to the output shaft of the motor, and a second bevel gear meshing with the first bevel gear. The second bevel gear is embedded in the powder storage bin through a rolling bearing. One end of the powder feeding screw is fixedly connected to the second bevel gear. The motor is fixedly mounted on a motor mounting plate, and the motor mounting plate is fixedly mounted below the powder storage bin.

[0006] Preferably, the powder outlet cover includes a support shaft, and the end of the powder feeding screw is provided with a support hole into which the support shaft can be inserted.

[0007] Preferably, the powder feeding screw is provided with a pair of positioning rods at one end relative to the drive assembly, which can abut against the powder outlet channel port.

[0008] This invention has the following advantages over existing technologies: the powder feeding screw is a trumpet-shaped screw with a thinner thread section inside the powder storage bin and a thicker thread section in the powder outlet channel. This design reduces resistance and ensures a smoother process when conveying milk powder through the thinner thread section to the outlet channel. The powder feeding screw is driven by a drive assembly to rotate, first conveying the milk powder from the storage bin to the outlet channel, where it falls through the powder drop hole at the bottom of the outlet cover. The conveying process ends when the drive assembly stops. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] As shown in Figure 1, a low-resistance precision powder pushing mechanism with a flared mouth includes a powder storage bin 1. A powder pushing and feeding screw 2 is provided at the bottom of the powder storage bin 1. One end of the powder pushing and feeding screw 2 is driven to rotate by a drive component 3 provided outside the powder storage bin 1. The powder storage bin 1 includes a powder outlet channel 11 into which the powder pushing and feeding screw 2 can be inserted. A powder outlet cover 4 that can support the powder pushing and feeding screw 2 is snapped onto the end of the powder outlet channel 11. A powder drop hole 41 is provided at the bottom of the powder outlet cover 4.

[0016] This solution presents a low-resistance, precision powder-pushing mechanism with a flared opening. The powder-pushing screw 2 is flared in shape, with a thinner thread section inside the powder storage bin 1 and a thicker thread section in the powder outlet channel 11. This design allows for smoother powder delivery with lower resistance when the powder is conveyed through the thinner thread section to the outlet channel 11. The powder-pushing screw 2 is driven by a drive assembly 3, which first transports the powder from the storage bin 1 to the outlet channel 11, where it falls through the powder drop hole 41 at the bottom of the outlet cover 4. The conveying process ends when the drive assembly 3 stops. The outlet cover 4 is connected to the outlet channel 11 via a snap-fit ​​structure.

[0017] Preferably, the drive assembly 3 includes a motor 32, a first bevel gear 33 fixedly connected to the output shaft of the motor 32, and a second bevel gear 34 meshing with the first bevel gear 33. The second bevel gear 34 is embedded in the powder storage bin 1 through a rolling bearing 35. One end of the powder pushing and feeding screw 2 is fixedly connected to the second bevel gear 34. The motor 32 is fixedly mounted on a motor fixing plate 31, and the motor fixing plate 31 is fixedly mounted below the powder storage bin 1.

[0018] The drive assembly 3 drives the first bevel gear 33 to rotate via the motor 32, the first bevel gear 33 drives the second bevel gear 34 to rotate, and the second bevel gear 34 drives the powder feeding screw 2 to rotate. The whole process is stable and smooth.

[0019] Preferably, the powder outlet cover 4 includes a support shaft 42, and the end of the powder feeding screw 2 is provided with a support hole 22 into which the support shaft 42 can be inserted.

[0020] This configuration effectively supports the powder feeding screw 2.

[0021] Preferably, the powder feeding screw 2 is provided with a pair of positioning rods 21 at one end relative to the drive assembly 3, which can abut against the port of the powder outlet channel 11.

[0022] Positioning rod 21 can improve the positional accuracy and rotational stability of the powder feeding screw 2.

[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
