[0028] Refer to the appendix Figure 3 and the appendix Figure 4 as well as the appendix Figure 5 and the appendix Figure 7 As shown, the ice cream swing arm mechanism 40 in this embodiment is arranged below the ice cream extrusion device 60. The ice cream swing arm mechanism 40 includes a swing arm 44, a rotary stepper motor 43, a motor mounting base 42, and a lifting drive assembly 41. The lifting drive assembly 41 is arranged at the bottom end of the front side plate in the cabinet 10. The top end of the lifting drive assembly 41 is fixedly connected to the motor mounting base 42, so that the lifting drive assembly 41 can drive the motor mounting base 42 to move up and down. The rotary stepper motor 43 is fixedly installed on the motor mounting base 42, and the output shaft of the rotary stepper motor 43 is connected to one end of the swing arm 44. The rotary stepper motor 43 can drive the swing arm 44 to rotate horizontally. The other end of the swing arm 44 is formed with an inward concave receiving groove 441. The outer shape of the notch of the receiving groove 441 is the same as the outer shape of the used ice cream cup 200. And when the rotary stepper motor 43 drives the swing arm 44 to rotate horizontally, the ice cream cup 200 placed in the receiving groove 441 will not shake.

[0029] Combined with reference to the appendix Figure 6 and the appendix Figure 8As shown, a notch 442 is provided on one side of the accommodation groove 441. An infrared sensor 80 is installed in the notch 442, and the infrared sensor 80 is connected to the control main board. The function of the infrared sensor 80 is to detect whether an ice cream cup 200 is placed in the accommodation groove 441. When it detects that an ice cream cup 200 is placed in the accommodation groove 441, the infrared sensor 80 sends a signal to the control main board, and the control main board then controls the ice cream extrusion device 60 to act and extrude ice cream into the lower ice cream cup 200.

[0030] Continue to refer to the appendix Figure 3 and the appendix Figure 4 As shown, the ice cream extrusion device 60 and the discharge port of the jam adding device 50 are at the same horizontal position. This structural design allows the swing arm 44 to switch horizontally between the ice cream extrusion device 60 and the jam adding device 50, realizing the addition of ice cream and jam.

[0031] Refer to the appendix Figure 4 As shown, the jam adding device 50 includes a material rack 51 for holding jam bottles, a pump body 52, a jam falling pipe 53, and a one-way valve 54. The pump body 52 is used to communicate with the jam bottle placed in the material rack 51.

It should be noted here that multiple jam bottles of different flavors can be placed in the above-mentioned material rack 51, and each jam bottle is correspondingly equipped with a pump body 52, a jam falling pipe 53, and a one-way valve 54. During use, consumers can select the corresponding flavor of ice cream through the touch screen 20 installed on the upper part of the front side plate of the frame. The touch screen 20 converts the ice cream flavor information selected by the consumers into an electrical signal and transmits it to the control main board, and the control main board then drives the pump body 52 in the corresponding flavor jam bottle to act according to the received electrical signal information, and extracts the jam in the corresponding jam bottle into the ice cream cup 200.

[0032] Combined with referring to the appendix Figure 1 and the appendix Figure 2 As shown, a material taking port 11 is provided on the front side plate of the machine shell 10. The setting of the material taking port 11 facilitates consumers to take out the ice cream cup 200 stored inside the machine shell 10 and place it in the accommodation groove 441 of the swing arm 44, and also facilitates taking out the ice cream cup 200 containing the made ice cream from the accommodation groove 441.

[0033] Continue to refer to the appendix Figure 1 and the appendix Figure 2As shown, in order to allow only consumers who have paid for the selected package to pick up the ice cream cup 200, a feeding port baffle mechanism 30 is installed at the feeding port 11. The feeding port baffle mechanism 30 is used to close or open the feeding port 11. That is, after the consumer pays for the ice cream package they have selected, the feeding port baffle mechanism 30 operates to open the feeding port 11, and the consumer can pick up the ice cream cup 200 placed inside the cabinet 10. Refer to the appendix Figure 2 As shown, in order to ensure that the consumer will not be pinched (pinched by the lower feeding port baffle mechanism 30) during the process of picking up the ice cream cup 200 through the feeding port 11, light grids 70 are installed on the left and right sides of the feeding port 11.

[0034] Refer to the appendix Figure 2 As described above, the feeding port baffle mechanism 30 includes a feeding port baffle 32, a push rod 31, and a driving unit. The driving unit is fixedly installed at the bottom end of the front side of the cabinet 10. The driving unit is fixedly connected to one end of the push rod 31 and is used to drive the push rod 31 to move up and down. The other end of the push rod 31 is fixedly connected to the feeding port baffle 32. The feeding port baffle 32 forms a vertical sliding connection with the feeding port 11. The driving unit is communicatively connected to the control main board. After the control main board receives the consumer payment information, the control main board sends an instruction message to the driving unit. The driving unit drives the feeding port baffle 32 to move downward through the push rod 31, and the feeding port 11 is exposed, so that the consumer can pick up the ice cream cup inside the cabinet 10.

[0035] To better understand the ice cream vending machine in this embodiment, the following briefly describes its working principle:

[0036] When a consumer uses the ice cream vending machine, the consumer selects the type of ice cream flavor they want to buy through the touch screen 20. After the ice cream flavor type is selected, payment information is displayed on the touch screen 20, reminding the consumer that they can make a scan payment or a cash payment. After the consumer completes the payment, payment completion information can be displayed on the touch screen 20, and the control main board controls the driving unit to act. The driving unit drives the material port baffle 32 to descend, making the material taking port 11 on the machine shell 10 exposed. At the same time, the control main board acts on the lifting driving component 41 in the ice cream swing arm mechanism 40. The lifting driving component 41 drives the swing arm 44 to move vertically upward and be located below the ice cream extrusion device 60. The consumer takes an ice cream cup from inside the machine shell 10 and places it in the receiving groove 441 on the swing arm 44. After the infrared sensor 80 on the swing arm 44 detects the ice cream cup in the receiving groove 441, the control main board sends an instruction to the rotating motor. The rotating motor drives the swing arm 44 to rotate horizontally and move below the jam adding component. The jam adding component drives the corresponding pump body 52 to act according to the flavor selected by the consumer, and extracts the corresponding flavor jam into the ice cream cup below. After the jam adding is completed, the rotating motor drives the swing arm 44 to rotate and reset, and the lifting driving component 41 drives the swing arm 44 to descend to the position of the material taking port 11. In this way, the consumer can conveniently take away the ice cream cup on the swing arm 44 through the material taking port 11 for consumption.
