Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0030] Figure 1 The schematic diagram of the structure of the heating type quantitative tapioca pearl feeding device in the utility model is shown. Figure 2 The exploded view of the heating type quantitative tapioca pearl feeding device in the utility model is shown. Figure 3 A cross-sectional view of the heating type quantitative tapioca pearl dosing device in the utility model is shown. Figure 4 Another angled cross-sectional view of the heating type quantitative tapioca pearl feeding device in the present invention is shown, the heating type quantitative tapioca pearl feeding device comprises: a tapioca pearl storage bin 1, a tapioca pearl feeding device 2 and a tapioca pearl discharging device 3; the tapioca pearl storage bin 1 is located above the tapioca pearl feeding device 2, and the tapioca pearl discharging device 3 is located in front of the tapioca pearl feeding device 2. The tapioca pearl storage bin 1 is used to store and store tapioca pearls, the tapioca pearl feeding device 2 is used to transport the tapioca pearls stored in the tapioca pearl storage bin 1 to the tapioca pearl discharging device 3 in an orderly manner, and the tapioca pearl discharging device 3 is used to quantitatively output the tapioca pearls transported by the tapioca pearl feeding device 2 to corresponding containers.

[0031] It should be noted that the tapioca pearl storage bin 1 has a accommodating cavity for storing tapioca pearls, that is, the tapioca pearl storage bin 1 stores tapioca pearls based on the accommodating cavity; the tapioca pearl feeding device 2 is provided with a flow cavity, and the tapioca pearl feeding device 2 is used to transport the tapioca pearls in the tapioca pearl storage bin to the tapioca pearl discharging device 3 in an orderly manner; the tapioca pearl discharging device 3 has a discharging channel, the accommodating cavity 12 is connected with the flow cavity 221, and the flow cavity 221 is connected with the discharging channel, and the tapioca pearl discharging device 3 is used to output the tapioca pearls transported by the tapioca pearl feeding device 2 to the corresponding container.

[0032] The accommodating chamber 12 is connected with the flow chamber 221 based on the first circulation channel 4, and the flow chamber 221 is connected with the discharge channel based on the second circulation channel 5. The bottom of the tapioca pearl storage bin is provided with a first pipe connection part 14, the top of the tapioca pearl feeding device is provided with a second pipe connection part 26, the bottom of the tapioca pearl feeding device is provided with a third pipe connection part 27, and the tapioca pearl discharge device is provided with a fourth pipe connection part 321; wherein the first pipe connection part 14 and the second pipe connection part 26 are connected to form a first circulation channel 4, and the third pipe connection part 27 and the fourth pipe connection part 321 form a second circulation channel 5. The first circulation channel 4 is used to transport the tapioca pearls in the tapioca pearl storage bin 1 to the flow chamber 221; the second circulation channel 5 is used to transport the tapioca pearls in the flow chamber 221 to the tapioca pearl discharge device 3, and the length of the second circulation channel 5 is fixed, and the second circulation channel 5 can accommodate multiple tapioca pearls, and the tapioca pearls stay in the second circulation channel 5 in advance, which improves the feeding speed of the heated quantitative tapioca pearls.

[0033] The tapioca pearl storage bin 1 comprises: a bin shell 11 and a receiving cavity 12 formed by the bin shell, the receiving cavity 12 is used to hold tapioca pearls, and the bin shell is used to isolate the receiving cavity 12 from the external environment, reduce the contact between the tapioca pearls in the receiving cavity 12 and the external environment, and reduce the tapioca pearls from being contaminated by the external environment. The bin shell comprises an outer layer 111 and an inner layer 112, a heating unit 13 is arranged between the outer layer 111 and the inner layer 112, and the heating unit 13 is arranged between the inner layer 112 and the outer layer 111; the heating unit 13 is evenly arranged on the surface of the receiving cavity 12 to avoid uneven heat and cold in the tapioca pearl storage bin 1, which causes some tapioca pearls to stick together, and is conducive to ensuring that the tapioca pearls can be clearly separated.

[0034] It should be noted that the heating unit 13 here can be a heating wire, and the heating wire is wound on the surface of the inner layer 112. This arrangement can increase the contact area between the heating wire and the inner layer 112, and speed up the heat transfer between the inside of the tapioca pearl storage bin 1 and the heating wire. The heating unit here can also be a plurality of heating resistors, and the plurality of heating resistor arrays are distributed on the surface of the inner layer 112. Each heating resistor is responsible for heating the temperature of a designated area. The plurality of heating resistors work simultaneously, and speed up the heat transfer between the inside of the tapioca pearl storage bin 1 and the heating resistors.

[0035] Furthermore, a lid 7 is provided on the top of the tapioca pearl storage bin 1, and the lid 7 is used to seal the entire tapioca pearl storage bin 1, so that the tapioca pearls will not directly contact the outside world, thereby reducing the efficiency of the tapioca pearls losing heat, playing a certain role in heat preservation, thereby preventing the tapioca pearls from sticking together due to a drop in temperature, and preventing the tapioca pearls from blocking the output end of the tapioca pearl storage bin 1 when the tapioca pearls are kept warm, so that the tapioca pearls can enter the tapioca pearl feeding device 2, ensuring that the tapioca pearls can enter the tapioca pearl feeding device 2 smoothly and with distinct particles; the lid is detachably mounted on the top of the tapioca pearl storage bin, and when tapioca pearls need to be added to the tapioca pearl storage bin, the lid can be temporarily removed from the top of the tapioca pearl storage bin, and the tapioca pearls can be directly poured into the tapioca pearl storage bin, and then the lid can be covered, which is conducive to directly loading the tapioca pearls into the tapioca pearl storage bin, reducing other cumbersome steps and speeding up the tapioca pearl loading speed.

[0036] The tapioca pearl feeding device comprises: a driving motor 21 and a flow mechanism 22, wherein the flow mechanism 22 has a flow chamber 221 and a driving unit arranged in the flow chamber, the driving motor is connected to the flow mechanism, and the flow mechanism 22 is driven by the driving motor 21 to transport the tapioca pearls to the tapioca pearl discharging device 3.

[0037] Furthermore, the driving unit includes: a first rotating blade 222 and a second rotating blade 223, the first rotating blade 222 and the second rotating blade 223 are used to transport the tapioca pearls one by one from the flow chamber 221 along a specified path to the tapioca pearl discharging device 3. The first rotating blade 222 is an 8-shaped blade, and the second rotating blade 223 is an 8-shaped blade. The first rotating blade 222 abuts against the second rotating blade 223, and the side surface of the first rotating blade 222 always abuts against the side surface of the second rotating blade 223 during the rotation of the first rotating blade 222.

[0038] Specifically, the initial matching state of the first rotating blade 222 and the second rotating blade 223 is that the middle area of ​​the first rotating blade 222 abuts against the top of the second rotating blade 223. When the first rotating blade 222 rotates 45° counterclockwise, the second rotating blade 223 also rotates 45° clockwise at the same time. During this process, the lower half of the first rotating blade 222 is tangent to the upper half of the second rotating blade 223, and the tangent point moves along the side of the first rotating blade 222 from the top of the lower half of the first rotating blade 222 to the middle of the lower half of the first rotating blade 222. When the first rotating blade 222 rotates 45° counterclockwise again, the second rotating blade 223 rotates 45° clockwise at the same time, that is, it rotates 90° compared with the initial matching state. During this process, the tangent point between the lower half of the first rotating blade 222 and the second rotating blade 223 is along the side of the first rotating blade 222 from the middle of the lower half of the first rotating blade 222 to the bottom end of the first rotating blade 222, and the bottom end of the first rotating blade 222 abuts against the middle of the second rotating blade 223. At this time, the positional relationship between the first rotating blade 222 and the second rotating blade 223 is opposite to the initial matching state of the first rotating blade 222 and the second rotating blade 223. The first rotating blade 222 and the second rotating blade 223 always maintain an abutting state during the rotation process, ensuring that the tapioca pearls can move along the specified path in the flow chamber 221, which is conducive to ensuring that the tapioca pearls enter the transport pipe 32 one by one from the flow chamber 221.

[0039] refer to Figure 2 , Figure 3 and Figure 4The output end of the driving motor 21 is connected to the first rotating blade 222 based on the coupling 23, and a driving gear 24 is provided at the connection between the driving motor 21 and the first rotating blade 222; the first rotating blade 222 is driven by the driving motor 21 to rotate with the geometric center of the first rotating blade 222 as the reference. The coupling 23 can transmit the power and movement of the output end of the driving motor 21 to the first rotating blade 222, ensuring that the mechanical equipment can work according to the predetermined requirements. When the output end of the driving motor 21 rotates counterclockwise, it drives the first rotating blade 222 to rotate counterclockwise and drives the driving gear 24 to rotate counterclockwise.

[0040] Furthermore, a driven gear 25 is provided at one end of the second rotating blade 223, and the driven gear 25 is meshed with the driving gear 24. When the driving gear 24 rotates counterclockwise, the driving gear 24 drives the driven gear 25 to rotate clockwise, and the clockwise rotation of the driven gear 25 drives the second rotating blade 223 to rotate clockwise. The clockwise rotation of the second rotating blade 223 can squeeze the tapioca pearls flowing into the flow chamber 221 from the first pipe from the upper half of the flow chamber 221 to the lower half of the flow chamber 221, thereby allowing the tapioca pearls to enter the second pipe. In this process, the tapioca pearls adhere to the inner wall of the flow chamber 221, ensuring that after the tapioca pearls move to the upper side of the input end of the second pipe, they will enter the second pipe under the action of gravity.

[0041] Further, the first rotating blade 222 is provided with more than one first arc groove 2221, and the first arc groove 2221 is evenly distributed on the first rotating blade 222; the second rotating blade 223 is provided with more than one second arc groove 2231, and the second arc groove 2231 is evenly distributed on the second rotating blade 223. In this embodiment, six first arc grooves 2221 are provided on the first rotating blade 222, of which three first arc grooves 2221 are located on the upper end surface of the first rotating blade 222, and the other three first arc grooves 2221 are located on the lower end surface of the first rotating blade 222; six second arc grooves 2231 are provided on the second rotating blade 223, of which three second arc grooves 2231 are located on the upper end surface of the second rotating blade 223, and the other three second arc grooves 2231 are located on the lower end surface of the second rotating blade 223. The first arc groove 2221 is used to increase the contact area with the second rotating blade 223, and the second arc groove 2231 is used to increase the contact area with the first rotating blade 222. When the first rotating blade 222 is located in the second arc groove 2231, the contact area between the first rotating blade 222 and the second rotating blade 223 is increased, thereby preventing the moisture carried by the tapioca pearls from flowing into the second pipe from the gap between the first rotating blade 222 and the second rotating blade 223; similarly, when the second rotating blade 223 is located in the first arc groove 2221, the contact area between the second rotating blade 223 and the first rotating blade 222 is increased, thereby preventing the moisture carried by the tapioca pearls from flowing into the second pipe from the gap between the first rotating blade 222 and the second rotating blade 223.

[0042] The tapioca pearl discharging device includes a downward pressure cylinder 31 and a transport pipe 32. The downward pressure cylinder 31 is inserted at the top of the transport pipe 32, and the output end of the downward pressure cylinder faces the discharge end of the transport pipe 32. The transport pipe 32 is used to output the tapioca pearls transported by the tapioca pearl feeding device to the corresponding container. The downward pressure cylinder is used to control the switch of the transport pipe 32. When the output end of the downward pressure cylinder moves to the end of the travel toward the discharge end of the transport pipe 32, the downward pressure cylinder closes the output function of the transport pipe 32; conversely, when the output end of the downward pressure cylinder moves to the end of the travel away from the discharge end of the transport pipe 32, the downward pressure cylinder opens the output function of the transport pipe 32.

[0043] Furthermore, a cylindrical rubber plug 8 is provided at the output end of the downward pressure cylinder 31, and the cylindrical rubber plug 31 can be driven by the downward pressure cylinder 31 to move in the discharge channel, that is, the cylindrical rubber plug 8 is driven by the downward pressure cylinder 31 to move between the top of the discharge end of the transport pipe 32 and the bottom of the discharge end of the transport pipe 32. When the downward-pressing cylinder 31 moves downward, it drives the cylindrical rubber plug 8 to move downward. When the cylindrical rubber plug 8 moves to the bottom of the discharge end of the transport pipe 32, the cylindrical rubber plug 8 blocks the output end of the second circulation channel 5, so that the tapioca pearls cannot flow from the second circulation channel 5 to the transport pipe 32; when the downward-pressing cylinder 31 moves upward, it drives the cylindrical rubber plug 8 to move upward. When the cylindrical rubber plug 8 is located at the top of the discharge end 32 of the transport pipe, the cylindrical rubber plug 8 has no contact with the output end of the second circulation pipe, so that the tapioca pearls can flow smoothly from the second circulation pipe into the transport pipe 32, and the tapioca pearls enter the corresponding cups along the transport pipe 32.

[0044] Furthermore, the bottom of the tapioca pearl storage bin 1 is in the shape of a funnel. The funnel-shaped design usually has the characteristics of two sides tilted inwards, and has a structure that is wide at the top and narrow at the bottom. This design can easily 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 first pipe. And the cross-sectional area that can be passed through the bottom of the tapioca pearl storage bin 1 is gradually reduced to the area that two tapioca pearls can pass through at the same time, so as to avoid multiple tapioca pearls being blocked at the bottom of the tapioca pearl storage bin 1, causing the tapioca pearls to be stuck at the output end of the tapioca pearl storage bin 1 and unable to move, thereby ensuring that the tapioca pearls can smoothly enter the first pipe from the output end of the tapioca pearl storage bin 1.

[0045] Furthermore, the first rotating blade 222 is made of metal, and the second rotating blade 223 is also made of metal. In this embodiment, the first rotating blade 222 is made of stainless steel, and the second rotating blade 223 is also made of stainless steel, and the stainless steel is 304 food grade stainless steel, which has a smooth surface and is not easy to adhere to food residues, so that the tapioca pearls are prevented from adhering to the first rotating blade 222 or the second rotating blade 223 during use, which is conducive to convenient cleaning of the first rotating blade 222 and the second rotating blade 223. Secondly, the 304 food grade stainless steel has strong durability and can maintain the stability and service life of the device.

[0046] The utility model also discloses a self-service vending machine, which includes the above-mentioned heating type quantitative tapioca pearls feeding device, the heating type quantitative tapioca pearls feeding device is fixed in the self-service vending machine, the heating type quantitative tapioca pearls feeding device is located above the milk tea making device, when the milk tea making device finishes making the milk tea, the milk tea is poured into a corresponding container, and then the heating type quantitative tapioca pearls feeding device transports the tapioca pearls quantitatively to the corresponding containers one by one.

[0047] In summary, the utility model provides a heating unit in the tapioca pearl storage bin, and the heating unit is provided on the surface of the inner layer, so that the internal temperature of the tapioca pearl storage bin is maintained, and the temperature of the tapioca pearls is prevented from dropping, which causes the tapioca pearls to stick together, thereby ensuring that the tapioca pearls are distinct; the utility model connects the accommodating chamber with the flow chamber and the flow chamber with the discharge channel, so that the tapioca pearls can be output from the tapioca pearl storage bin to the corresponding container; the utility model is provided with a flow mechanism, and the flow mechanism transports the tapioca pearls in an orderly manner to a pipe that can accommodate a fixed number, thereby ensuring that the number of tapioca pearls put in each time is consistent.
