Description

Technical Field

[0001] The present invention relates to the technical field of preparation of whitening and skin-care drinks, and in particular to a device and method for preparing a natural whitening and skin-care drink. Background Art

[0002] When preparing natural whitening and skincare drinks, ensuring uniform mixing of ingredients is crucial for achieving their effectiveness. However, existing preparation equipment often has design independence between the stirring and discharging stages, which can lead to stratification of the mixed liquid after stirring. This stratification not only affects the appearance and taste of the drink but can also reduce the uniform distribution of its nutrients, further impacting the final product's effectiveness and consumer experience.

[0003] Traditional mixing devices typically utilize fixed mixing blades for mixing, with the mixing and discharging processes being independent. After mixing, the mixture must be discharged through a separate valve or pumping system. During this process, gravity causes denser powdered ingredients to settle, leading to stratification of the mixture and uneven distribution of different ingredients. This stratification is particularly pronounced for beverages containing both powdered and liquid ingredients, impacting both quality and waste during production. Summary of the Invention

The shaped array is arranged for stirring and mixing the raw materials. The rotation of the driving wheel is driven by the rotating shaft 231. The engagement between the driving wheel and the planetary gear makes it possible for the rotation of the rotating shaft 231 to synchronously drive the rotation of the stirring blade 26 to achieve efficient mixing of the powder and liquid raw materials. The first stepper motor 22 is used to drive the rotating shaft 231 to rotate in the forward or reverse direction.

The coordinated work of stirring and discharging can be achieved to effectively reduce the risk of stratification of the mixed liquid. By integrating the stirring and discharging functions, a more efficient mixing effect and better liquid state management can be achieved, thereby improving the overall quality of the beverage and consumer satisfaction.

[0056] Among them, the rotating mechanism 23 includes: a rotating shaft 231, which is transmission-connected to the output end of the first stepper motor 22; a screw shaft 232, which is embedded in the bottom of the rotating shaft 231, and the external thread opened on the screw shaft 232 facilitates mutual cooperation with the internal thread of the nut seat 242.

[0057] Among them, the movable sealing mechanism 24 includes: a connecting tube 241, which is cylindrical in shape, and the connecting tube 241 provides space for the relative movement between the screw shaft 232 and the nut seat 242; a nut seat 242, the nut seat 242 is connected to the top of the connecting tube 241, and the nut seat 242 is threadedly inserted and matched with the screw shaft 232; a supporting slide 243, the supporting slide 243 is connected to the outside of the connecting tube 241 in an annular array, and a plurality of limiting grooves are opened in an annular array on the inner wall of the mixing box 21, and the end of the supporting slide 243 slides with the inner cavity of the limiting groove, so that the movement of the connecting tube 241 is limited by the limiting groove, so that the linear motion of the connecting tube 241 is more stable; an elastic sealing component, the elastic sealing component is connected to the bottom of the connecting tube 241, and the elastic sealing component is used to seal the inner cavity of the liquid outlet. The elastic blocking assembly includes: a first sleeve 244, which is connected to the bottom of the connecting tube 241; a telescopic rod 245, which is slidably inserted into the inner cavity of the first sleeve 244; a blocking block 246, which is connected to the end of the telescopic rod 245; a first spring 247, which is movably sleeved on the outside of the first sleeve 244 and the telescopic rod 245, and the first spring 247 is used to elastically support the blocking block 246. When the rotating shaft 231 drives the screw shaft 232 to rotate forward, the screw shaft The rotation direction of 232 is a non-screwing direction relative to the nut seat 242, so that the screw shaft 232 will not be threadedly engaged with the nut seat 242 at this time. Through the sliding cooperation between the first sleeve 244 and the telescopic rod 245, it is convenient to provide movement space for the relative movement between the blocking block 246 and the connecting tube 241. At the same time, the linear movement of the blocking block 246 relative to the connecting tube 241 is also more stable. Through the compression deformation of the first spring 247, the elastic support of the blocking block 246 is facilitated, so that the blocking block 246 has a better effect of sealing the liquid outlet.

10. A method for preparing a natural whitening and skin care beverage, characterized in that: The method for preparing the natural whitening skin care beverage comprises a preparation device for the natural whitening skin care beverage according to any one of claims 1 to 9, and the method specifically comprises the following steps: S1, according to the skin needs, select the corresponding raw materials on the operation panel (11), and put the corresponding raw materials in the powder feeding device (3) and the liquid feeding box (4) into the mixing box (21); S2, through the rotation of the first stepper motor (22), the rotation of the rotating shaft (231) is driven to rotate in the forward direction, so that the rotating shaft (231) drives the rotation of the driving wheel, and the driving wheel drives the multiple planetary wheels to rotate, so that the rotating shaft can drive the stirring blade (26) to rotate, so as to achieve the stirring and fusion of the powdered raw materials and the liquid raw materials in the inner cavity of the mixing and batching box (21). After the fusion is completed, the first stepper motor (22) will be reversed, so that the rotating shaft (231) drives the screw shaft (232) to rotate in the opposite direction, and the compression deformation of the first spring (247) facilitates the elastic support of the connecting cylinder (241), so that the connecting cylinder (241) drives The nut seat (242) has a tendency to move upward to assist the threaded engagement between the nut seat (242) and the screw shaft (232), so that when the screw shaft (232) rotates in the opposite direction, it can engage with the thread of the nut seat (242), and through the sliding interlacing between the supporting slide rod (243) and the mixing and batching box (21), it is convenient to linearly limit the sliding of the connecting tube (241), so that the connecting tube (241) can drive the synchronous upward movement of the first sleeve (244), the telescopic rod (245) and the blocking block (246). At this time, the blocking block (246) no longer blocks the inner cavity of the liquid outlet, and the beverage after the proportioning is completed can flow out of the liquid outlet for drinking.
