Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Figure 1 The schematic diagram of the structure of the quantitative auxiliary material discharging device in the utility model is shown. Figure 2 An exploded view of the quantitative auxiliary material discharging device in the utility model is shown, and the quantitative auxiliary material discharging device includes: a driving motor 1, a discharging mechanism 3 and a rotating mechanism 2, the driving motor 1 is used to drive the rotating mechanism 2 to rotate in the discharging mechanism 3, the discharging mechanism 3 is used to store auxiliary materials, and the rotating mechanism 2 is used to quantitatively output auxiliary materials under the drive of the driving mechanism 1.

[0028] The rotating mechanism 2 includes: a rotating unit 21 and a rotating blade 23. The rotating unit 21 is connected to the driving end of the rotating blade 23. The detection end of the photoeye 22 faces the rotating unit 21. The rotating end of the rotating blade 23 is inserted into the inside of the discharging mechanism. The output end of the driving motor 1 is connected to the rotating mechanism 2. The rotating mechanism 2 is driven by the driving motor 1 to rotate in the discharging mechanism 3. In this embodiment, the rotating blade 23 includes a rotating shaft 232 and a plurality of blades 231 located on the rotating shaft. In the embodiment of the utility model, six blades 231 are arranged on the rotating shaft, and the six blades 231 are arranged in an array on the rotating shaft, and the angle formed between two adjacent blades is 60°. A placement cavity is formed between two adjacent sub-blades 231, that is, six placement cavities are formed on the rotating blade 23, and the entire transmission blade 23 is arranged horizontally in the discharging cavity of the discharging mechanism 3.

[0029] It should be noted that the rotating unit 21 may include a driving gear 211 and a driven gear 212, the driving gear 211 and the driven gear 212 are meshed, the driving gear 211 is connected to the output end of the driving motor 1, and the driven gear 212 is connected to the rotating blade 23. When the output end of the driving motor 1 rotates clockwise, the driving motor 1 drives the driving gear 211 to rotate clockwise, the driving gear 211 rotates clockwise, drives the driven gear 212 to rotate counterclockwise, and the counterclockwise rotation of the driven gear 212 drives the rotating blade 23 to rotate counterclockwise.

[0030] The rotating unit 21 can also be two wheels and a transmission crawler, wherein the first wheel is connected to the output end of the driving motor 1, and the second wheel is not in contact with the driving motor 1, and the second wheel is connected to the rotating blade 23, and the transmission crawler covers the first wheel and the second wheel. When the output end of the driving motor 1 rotates clockwise, the first wheel is driven to rotate clockwise, and the first wheel rotates clockwise to drive the first transmission crawler to move, thereby driving the second wheel to rotate clockwise, and the second wheel drives the rotating blade 23 to rotate clockwise.

[0031] Figure 3 The cross-sectional view of the quantitative auxiliary material discharging device in the utility model is shown, and the discharging mechanism 3 includes: an auxiliary material barrel 31 and an output pipe 32. The output pipe 32 is arranged below the auxiliary material barrel 31, and the auxiliary material barrel 31 is inserted on the output pipe 32. The auxiliary material barrel 31 includes a barrel body and a receiving cavity formed by the barrel body, and the output pipe 32 is connected to the receiving cavity. The auxiliary material barrel 31 is used to store the auxiliary materials required for milk tea, and the output pipe 32 is used to output the auxiliary materials in the auxiliary material barrel 31 to the corresponding container.

[0032] Furthermore, a lid 33 is provided on the top of the auxiliary material barrel 31. The lid 33 is detachably mounted on the top of the storage barrel. When auxiliary materials need to be added to the storage barrel, the lid 33 can be temporarily removed from the top of the storage barrel, and the auxiliary materials can be directly poured into the storage barrel, and then the lid 33 can be covered, which is conducive to the direct loading of auxiliary materials into the storage barrel, reducing other cumbersome steps and speeding up the loading of auxiliary materials. Secondly, the lid 33 also plays a sealing role. When the lid 33 seals the space in the auxiliary material barrel 31, it reduces the flow of air in the barrel, greatly reduces the contact between the auxiliary materials and the outside air, and then reduces the oxidation reaction between the auxiliary materials and oxygen, so as to maintain the freshness of the auxiliary materials.

[0033] Furthermore, an interference fit can be adopted between the auxiliary material barrel 31 and the output pipe 32. The interference fit between the auxiliary material barrel 31 and the output pipe 32 can eliminate the gap between the auxiliary material barrel 31 and the output pipe 32, reduce the risk of the auxiliary material overflowing from the gap between the auxiliary material barrel 31 and the output pipe 32, achieve a tight connection between the auxiliary material barrel 31 and the output pipe 32, and improve the stability and reliability of the discharge structure. Secondly, when the auxiliary material barrel 31 is assembled into the output pipe 32, a certain axial pressure needs to be applied to improve the connection strength between the auxiliary material barrel 31 and the output pipe 32, so that the discharge structure can withstand a larger load, that is, the discharge structure can carry more auxiliary materials.

[0034] Furthermore, the upper part of the output pipe 32 is funnel-shaped. The funnel-shaped design is usually characterized by two sides being inclined inwards, and having a structure that is wide at the top and narrow at the bottom. This design can conveniently introduce liquid or granular substances from the wider upper end and concentrate and guide them through the gradually narrowing lower end. The funnel can guide the flow direction of the liquid or substance, ensuring that they flow along a predetermined path and can enter the output pipe 32.

[0035] Figure 4 Another angled cross-sectional view of the quantitative auxiliary material dispensing device in the utility model is shown, wherein a first rotating hole is provided in the output pipe 32, and the first rotating hole is used to bear one end of the rotating shaft 232, and a second rotating hole is provided on the side wall opposite to the side wall where the first rotating hole is located to provide support force for the other end of the rotating shaft 232. The first rotating hole and the second rotating hole cooperate to provide support force for both ends of the rotating shaft 232, so that the rotating shaft 232 can rotate at a specified position in the output pipe 32, which is conducive to ensuring that the rotating blade 23 rotates stably in the output pipe 32.

[0036] refer to Figure 1 and Figure 2, more than one connecting handle 4 is provided on the surface of the output pipe 32, and the middle area of ​​any of the connecting handles 4 is recessed to form a connecting plate, and more than one connecting hole is provided on the connecting plate. In this embodiment, two connecting handles 4 are provided on the surface of the output pipe 32, and two connecting holes are provided on the connecting plate, and the two connecting handles 4 are located on two opposite sides of the output pipe 32. The connecting handle 4 is used to provide a support point so that the output pipe 32 can be fixed at a specified position, reducing the vibration of the milk tea quantitative auxiliary material dispensing device during operation, and the risk of changing the position of the milk tea quantitative auxiliary material dispensing device under the influence of multiple vibrations, which is conducive to fixing the milk tea quantitative auxiliary material dispensing device at a specified position. And the connecting handle can also provide a force point, which is convenient for maintenance personnel to lift or move the entire quantitative auxiliary material dispensing device.

[0037] Furthermore, the rotating unit 21 is provided with more than one photo-eye detection point 24, and the photo-eye detection points 24 are distributed in an array on the rotating unit 21. In this embodiment, the rotating unit 21 is provided with six photo-eye detection points 24, and the angle formed between any two adjacent photo-eye detection points 24 is 60°. One of the five photo-eye detection points 24 corresponds to one of the six sub-blades 231. When the rotating unit 21 rotates 60°, one of the placement cavities rotates from facing the auxiliary material barrel 31 to facing the inner wall of the output pipe 32. At this time, the auxiliary material in the placement cavity flows downward along the inner wall of the output pipe 32 under the action of gravity, and then flows into the corresponding container. At the same time, the placement cavity adjacent to this placement cavity rotates to the original position of this placement cavity, and blocks the output end of the auxiliary material barrel 31 to prevent the auxiliary material from flowing out excessively along the output pipe 32, so as to ensure the consistency of the quality of each discharge and achieve standardization. A photoeye is provided on one side of the rotating unit, and the detection end of the photoeye faces the photoeye detection point, and the detection end of the photoeye is recessed to form a detection groove. When the rotating unit is a driving gear and a driven gear, the driving gear is located in the detection groove, and the driving gear has no contact with the detection groove. The end face of the detection groove and the center of the driving gear are located on the same axis, ensuring that the detection end of the photoeye can accurately detect the movement of the photoeye detection point 24. Similarly, when the rotating unit is a first rotating wheel and a second rotating wheel, the first rotating wheel is located in the detection groove, and the first rotating wheel has no contact with the detection groove. The end face of the detection groove and the center of the first rotating wheel are located on the same axis, ensuring that the detection end of the photoeye can accurately detect the movement of the photoeye detection point 24.

[0038] Further, the discharging mechanism 3 also includes more than one fixing frame 5, the fixing frame 5 is in the shape of a triangle, and more than one through hole is provided on the two right-angled sides of the fixing frame 5. Among them, two through holes are provided on the right-angled side horizontal to the ground, and the two through holes are used to fix the fixing frame 5 at a specified position, and a through hole is provided on the right-angled side perpendicular to the ground, and this through hole is fixed with the connecting hole 4 on the connecting handle by screws, so that the fixing frame 5 is fixedly connected with the connecting handle, that is, the vertical side of the fixing frame 5 here can be supported on the connecting handle 4, and the fixing frame 5 can be fixed on the connecting hole of the connecting handle by screws, so that the fixing frame 5 can rely on the connecting handle 4 to achieve the support limit and body fixation, so that the connecting handle 4 can have a better fixing effect on the fixing frame 5. In this embodiment, the discharging mechanism 3 also includes two fixing frames 5, and the connection of the fixing frame 5 with the connecting holes at different positions can adjust the height of the output pipe 32, and then adjust the height of the entire milk tea quantitative auxiliary material discharging device, so that the entire device can adapt to the working environment.

[0039] Furthermore, a control module is provided in the device for quantitatively discharging auxiliary materials, and the control module is electrically connected to the photoeye 22, and the control module is electrically connected to the drive motor 1. The drive motor 1 starts to rotate after receiving the rotation instruction, and the drive motor 1 rotates clockwise and is driven by the rotation unit 21, so that the rotating blade 23 rotates clockwise. When the photoeye 22 detects that the rotating unit 21 can rotate from one photoeye detection point 24 to the next photoeye detection point 24, the photoeye 22 generates an electrical signal and sends the electrical signal to the control module. The control module sends a corresponding instruction to the drive motor 1 according to the electrical signal, and then the drive motor 1 stops rotating after receiving the corresponding instruction, so that the rotating blade 23 stops at the corresponding position, and two adjacent sub-rotating blades 23 block the output end of the auxiliary material barrel 31 to prevent the auxiliary material from continuing to flow into the output pipe 32.

[0040] Furthermore, the rotating blade 23 is made of metal. In this embodiment, the rotating blade 23 is made of 304 food grade stainless steel. The stainless steel is 304 food grade stainless steel, which has a smooth surface and is not easy to adhere to food residues, thereby preventing auxiliary materials from adhering to the rotating blade 23 during use, and facilitating the cleaning of the rotating blade 23. Secondly, the 304 food grade stainless steel is highly durable, and even if it is immersed in a solution containing fruit for a long time, it will not be corroded by fruit acid with poor acidity, and can maintain the stability and service life of the device.

[0041] The utility model also proposes a self-service milk tea vending machine, which includes the quantitative auxiliary material dispensing device and the milk tea making device, wherein the quantitative auxiliary material dispensing device is located above the milk tea making device, and when the milk tea making device finishes making the milk tea, it is poured into a designated container, and then the quantitative auxiliary material dispensing device puts the auxiliary material into the designated container accurately and quantitatively, so that the milk tea and the auxiliary material are fully mixed to form a cup of milk tea.

[0042] To sum up, the utility model drives the rotating blades to rotate at a fixed angle through the rotating unit, so that the auxiliary materials carried by the rotating blades flow out along the discharging mechanism, ensuring that the amount of auxiliary materials added each time is consistent, and placing the auxiliary materials in the discharging mechanism is beneficial to reduce the contact between the auxiliary materials and the outside world and reduce the risk of contamination of the auxiliary materials; secondly, the photoeye detects the rotation angle of the rotating unit to ensure that the rotating unit rotates at a fixed angle each time, thereby ensuring that the amount of auxiliary materials added each time is consistent.
