[0001] The utility model relates to the technical field of extraction, in particular to an extraction device and an automatic coffee vending machine. Background Art

[0002] With the improvement of people's living standards and the continuous improvement of the requirements for the quality of life, more and more people will buy some beverages to meet their own needs, and coffee is one of them.

[0003] Coffee refers to a beverage made from roasted and ground coffee beans. In general, coffee capsules are brewed in a coffee vending machine, which requires the use of an extraction device. Although the existing extraction devices can complete the extraction of coffee powder, the extraction effect is not good, resulting in the taste of the brewed coffee not being able to reach the satisfaction of consumers. Summary of the Utility Model

[0004] To achieve the above object, the utility model provides the following technical solutions:

[0005] An extraction device includes a control board, a motor, and a limit board. The control board is electrically connected to the motor. A limit member and a fixing piece are installed on the output shaft of the motor. An extraction head is installed at the end of the output shaft of the motor through a fixing plate. A pin is connected between the extraction head and the fixing plate, and a spring is sleeved on the pin. The fixing piece is connected to a slider, and the slider is slidably arranged on a guide rail through a limit piece. The limit board is installed on the guide rail, and both the guide rail and the control board are fixed on a main body support plate. A top sensor and a bottom sensor are respectively arranged at the top and bottom of the limit board. The extraction head includes a water pipe port, a sealing member, and a needle. The needle is installed on the sealing member, and the sealing member is connected to the water pipe port. The water pipe port is communicated with a water source.

[0006] As a further scheme of the utility model: A first protective cover is installed outside the control board to protect the control board and prevent it from being damaged.

[0007] As a further scheme of the utility model: The control board is fixed on the main body support plate through a support plate, with good connection firmness and not easy to fall off.

[0008] As a further scheme of the utility model: A second protective cover is installed outside the limit board to protect the limit board.

[0009] As a further scheme of the utility model: The sealing member is connected to the water pipe port through a fixing member to prevent the sealing member from detaching from the water pipe port and ensure the sealing effect.

[0010] As a further scheme of the utility model: The sealing member is made of silicone material, with easily available raw materials, convenient for processing, and good sealing effect.

[0011] As a further solution of the present utility model: a decorative plate is further installed on the main body support plate to beautify the appearance and have a good decorative effect.

[0012] An automatic coffee vending machine includes the extraction device described above.

[0013] The working steps of the extraction device are as follows:

[0014] The control board issues an extraction instruction, the motor rotates forward, the output shaft of the motor drives the fixed piece and the water pipe port to move, the fixed piece drives the limit piece to move on the guide rail through the slider, the water pipe port drives the seal and the needle to move. When the limit piece moves to the position of the bottom sensor of the limit board, the sensor sends a signal to the control board, the control board sends a stop instruction, and the motor stops rotating. At this time, the needle has punctured the lower capsule and the seal seals the top of the capsule by extrusion. The water pipe port starts to inject water and runs for the time set by the control board;

[0015] When the time set by the control board ends, the control board issues a return instruction, the motor rotates reversely, the output shaft of the motor drives the fixed piece to move, the fixed piece drives the limit piece to move on the guide rail through the slider. When the limit piece moves to the position of the top sensor of the limit board, the sensor sends a signal to the control board, the control board sends a stop instruction, and the motor stops rotating, and the entire extraction process ends.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] The product is reasonably designed and has a simple structure. It uses the forward and reverse rotation of the motor to realize the puncture and return of the capsule, and uses the extrusion of the seal on the capsule to realize sealing, ensuring that all the coffee powder in the capsule can be brewed, and the extraction effect is good.
