The top dead center sensor UD is, for example, provided on the aforementioned bracket 1023, and a switch or a pressed part (not labeled) thereof faces the follower 920.

When the sealing member 70 is moved to the lowered position, the extension arm 921 of the follower 920 will gradually approach the bottom dead center sensor BD until it touches the switch of the bottom dead center sensor BD. At this time, the bottom dead center sensor BD can send a signal to the main board MB1 through wireless or wired method, so that the main board MB1 determines whether the sealing member 70 has reached the lowered position. At this time, the main board MB1 will stop the lifting mechanism 90 to continue Driving seal member 70.

On the other hand, when the sealing member 70 is moved to the raised position, the follower 920 will gradually approach the top dead center sensor UD until the switch of the top dead center sensor UD is pressed. At this time, the top dead center sensor UD can send a signal to the main board MB1 through wireless or wired method, so that the main board MB1 determines whether the sealing member 70 has reached the lifting position. At this time, the main board MB1 will stop the lifting mechanism 90 to continue Driving seal member 70.

Of course, similarly, the present invention is not limited to the design or type of the aforementioned bottom dead center sensor BD and top dead center sensor UD. For example, in other embodiments, it is used to detect whether the sealing member 70 has been positioned. The sensor can also be changed to a non-contact sensor, such as a light sensor using laser or infrared. In this case, when the sealing member 70 is positioned, such as a lowered position or a raised position At this time, the position sensor can be triggered to realize the function of determining whether to position, and it is not necessary to directly touch or press the sensor.

At that time, the first tank position sensor D1 can be touched by the first storage tank 10 to notify the main board MB1 of the extraction device 1 that the first storage tank 10 has been positioned; Then, the user may, for example, press a corresponding key from the operation interface 1021 to lower the lifting mechanism 90 to the sealing member 70, or the main board MB1 may receive a signal of the first slot position sensor D1 immediately or pass a specific After time, the lifting mechanism 90 is automatically driven to drive the sealing member 70, so that the sealing member 70 is lowered and the opening O of the first storage tank 10 is automatically sealed; during the lowering of the sealing member 70, the bottom dead center sensor BD may be subjected to The pressure of the lifting mechanism 90 sends a signal to the main board MB1 of the extraction device 1 that the sealing member 70 has indeed sealed the first storage tank 10. At this time, the main board MB1 can stop the lifting mechanism 90 to stop the lifting mechanism 90 from continuing Drive The sealing member 70 moves downward. At the same time or before the first storage tank 10 is installed, the user can assemble the second storage tank 20 on the carrier shell 107 and pass the liquid outlet connector 21 of the second storage tank 20 through the carrier shell. The perforation 1071 of the piece 107 is connected to the valve body 30. At that time, if the second storage tank 20 is actually connected to the valve body 30, the second storage tank 20 can correctly trigger the second tank position sensor D2, the second tank The body position sensor D2 can notify the main board MB1 of the extraction device 1 that the second storage tank 20 has been positioned and is actually docked with the valve body 30. Here, it is added that the motherboard MB1 can also be changed to an automatic order immediately after receiving the signals of the first slot position sensor D1 and the second slot position sensor D2, or after a specific time. The lifting mechanism 90 drives the sealing member 70, but the present invention is not limited thereto.

In a mixture of liquid and raw material.

After completing the pre-extraction preparation operation, the user can then press the extraction start button on the operation interface 1021 to cause the extraction device 1 to perform the extraction process, or the main board MB1 can automatically start the extraction after a predetermined time of the stirring member 810 is started. The air device 50 automatically starts the extraction operation. As mentioned above, after the suction device 50 is started, the gas in the first storage tank 10 can be gradually extracted through the suction channel 60, so that the internal pressure of the first storage tank 10 can be gradually decreased at a specific decompression rate. The pressure sensor P1 can continuously detect the internal pressure of the first storage tank 10 to transmit a signal about the internal pressure of the first storage tank 10 to the motherboard MB1 at any time. The motherboard MB1 will be based on the internal pressure value and The predetermined pressure value of the extraction determines whether to close or fine-tune the opening degree of the extraction device 50, so as to stop continuing to depressurize the first storage tank 10 or fine-tune the decompression rate of the first storage tank 10, so that the first storage The internal pressure of the tank body 10 can more accurately approach the set predetermined pressure. When the main board MB1 determines that the internal pressure of the first storage tank 10 reaches the predetermined pressure required for the extraction, the main board MB1 can automatically open the valve body 30 immediately or after a specific time, so that the second storage tank 20 The liquid can flow into the first storage tank body 10. It can be known that the extraction device 1 of this embodiment can implement a one-button automation or a fully automated extraction process.
