[0161] In Embodiment 1, the controller 9 is a switch 91 for monitoring the operation of the liquid guiding module 4. The switch 91 is arranged in the inner cavity of the housing 1. The switch 91 is electrically connected to the liquid pumping pump 2. When the liquid guiding module 4 moves upward, the switch 91 starts the liquid pumping pump 2 to work. When the liquid guiding module 4 moves downward, the switch 91 stops the liquid pumping pump 2 from working.

[0162] Solution 1: The switch 91 is a micro switch. The micro switch is arranged in the housing 1 and is located above the slider 83. The pressing part of the micro switch faces the slider 83;

[0163] When the liquid guiding module 4 moves upward, the slider 83 touches the micro switch to open the micro switch, and the liquid pumping pump 2 works. When the liquid guiding module 4 moves downward, the slider 83 moves away from the micro switch to close the micro switch, and the liquid pumping pump 2 stops working.

[0164] Embodiment 2. The controller 9 is a liquid shortage state detection device 92 for detecting whether the liquid storage bottle 10 is short of liquid. The liquid shortage state detection device 92 is arranged in the housing 1. The liquid shortage state detection device 92 is electrically connected to the liquid extraction pump 2. When the liquid shortage state detection device 92 detects that the liquid storage bottle 10 is not short of liquid, the liquid shortage state detection device 92 turns on the power supply of the liquid extraction pump 2. When the liquid shortage state detection device 92 detects that the liquid storage bottle 10 is short of liquid, the liquid shortage state detection device 92 turns off the power supply of the liquid extraction pump 2.

[0165] Solution 1: The liquid shortage state detection device 92 is an infrared pair tube device. The infrared pair tube device includes an infrared emitting tube and an infrared receiving tube. The infrared emitting tube and the infrared receiving tube face each other and are arranged on the side wall of the liquid storage bottle accommodating cavity 11 near its bottom. The liquid storage bottle accommodating cavity 11 is provided with a light-transmitting hole corresponding to the positions of the infrared emitting tube and the infrared receiving tube.

[0166] When the user places the liquid storage bottle 10 in the liquid storage bottle accommodating cavity 11, if there is liquid in the liquid storage bottle 10, when the light generated by the infrared generating tube passes through the light-transmitting hole and the liquid storage bottle 10, the light generated by the infrared generating tube is deflected, resulting in the infrared receiving tube being unable to receive the light, thereby sending out a signal indicating no liquid shortage. The liquid shortage state detection device 92 turns on the power supply of the liquid extraction pump 2.

[0167] If the liquid storage bottle 10 is short of liquid, when the light generated by the infrared generating tube passes through the light-transmitting hole and the liquid storage bottle 10, since the liquid storage bottle 10 is short of liquid, the light generated by the infrared generating tube will not be refracted, and the infrared receiving tube receives the light, thereby sending out a signal indicating liquid shortage. The liquid shortage state detection device 92 turns off the power supply of the liquid extraction pump 2.

[0168] Solution 2: It further includes a liquid storage bottle 10. A magnetic floating ball is arranged inside the liquid storage bottle 10. The liquid shortage state detection device 92 is a reed switch. The reed switch is arranged on the side wall of the liquid storage bottle accommodating cavity 11 near its bottom. The reed switch is electrically connected to the liquid extraction pump 2. The reed switch controls the start and stop of the liquid extraction pump 2.

[0169] When the user places the liquid storage bottle 10 in the liquid storage bottle accommodating cavity 11, if there is liquid in the liquid storage bottle 10, the magnetic floating ball floats on the liquid surface, the magnetic floating ball is far away from the reed switch, and the reed switch sends out a signal indicating no liquid shortage. The liquid shortage state detection device 92 turns on the power supply of the liquid extraction pump 2.

[0170] If the liquid storage bottle 10 is short of liquid, the magnetic floating ball approaches the reed switch, and the reed switch sends out a signal indicating liquid shortage. The liquid shortage state detection device 92 turns off the power supply of the liquid extraction pump 2.

[0171] Embodiment 3. The controller 9 includes a liquid shortage state detection device 92 for detecting whether the liquid storage bottle 10 is short of liquid and a switch 91 for monitoring the operation of the liquid guiding module 4; the liquid shortage state detection device 92 and the switch 91 are arranged in the housing 1, and the liquid shortage state detection device 92, the switch 91 and the liquid extraction pump 2 are connected in series; when the liquid shortage state detection device 92 detects that the liquid storage bottle 10 is not short of liquid, when the liquid guiding module 4 moves upward, the switch 91 starts the liquid extraction pump 2 to work, and when the liquid guiding module 4 moves downward, the switch 91 stops the liquid extraction pump 2 from working. When the liquid shortage state detection device 92 detects that the liquid storage bottle 10 is short of liquid, the liquid shortage state detection device 92 disconnects the power supply of the liquid extraction pump 2.

[0172] The liquid shortage state detection device 92 is an infrared pair tube device, which includes an infrared emitting tube and an infrared receiving tube. The infrared emitting tube and the infrared receiving tube face each other and are arranged on the side wall of the liquid storage bottle accommodating cavity 11 near its bottom. The liquid storage bottle accommodating cavity 11 is provided with light-transmitting holes corresponding to the positions of the infrared emitting tube and the infrared receiving tube.

[0173] When the user places the liquid storage bottle 10 in the liquid storage bottle accommodating cavity 11, if there is liquid in the liquid storage bottle 10, when the light generated by the infrared generating tube passes through the light-transmitting hole and the liquid storage bottle 10, the light generated by the infrared generating tube is deflected, resulting in the infrared receiving tube being unable to receive the light, thereby sending out a signal indicating no liquid shortage, and the liquid shortage state detection device 92 turns on the power supply of the liquid extraction pump 2.

[0174] If the liquid storage bottle 10 is short of liquid, when the light generated by the infrared generating tube passes through the light-transmitting hole and the liquid storage bottle 10, since the liquid storage bottle 10 is short of liquid, the light generated by the infrared generating tube will not be refracted, and the infrared receiving tube receives the light, thereby sending out a signal indicating liquid shortage, and the liquid shortage state detection device 92 disconnects the power supply of the liquid extraction pump 2.

[0175] The switch 91 is a micro switch, which is arranged in the housing 1 and above the slider 83, and the pressing part of the micro switch faces the slider 83;

[0176] When the liquid guiding module 4 moves upward, the slider 83 touches the micro switch to open the micro switch, and the liquid extraction pump 2 works. When the liquid guiding module 4 moves downward, the slider 83 moves away from the micro switch to close the micro switch, and the liquid extraction pump 2 stops working.

[0177] Therefore, the start and stop of the liquid extraction pump 2 are jointly controlled by the liquid shortage state detection device 92 and the switch 91.

[0178] Embodiment 4. The controller 9 includes a liquid shortage state detection device 92 for detecting whether the liquid storage bottle 10 is short of liquid and a switch 91 for monitoring the operation of the liquid guiding module 4; the liquid shortage state detection device 92 and the switch 91 are arranged in the housing 1, and the liquid shortage state detection device 92, the switch 91 and the liquid extraction pump 2 are connected in series; when the liquid shortage state detection device 92 detects that the liquid storage bottle 10 is not short of liquid, when the liquid guiding module 4 moves upward, the switch 91 starts the liquid extraction pump 2 to work, and when the liquid guiding module 4 moves downward, the switch 91 stops the liquid extraction pump 2 from working. When the liquid shortage state detection device 92 detects that the liquid storage bottle 10 is short of liquid, the liquid shortage state detection device 92 cuts off the power supply of the liquid extraction pump 2.

[0179] It further includes a liquid storage bottle 10. A magnetic float is arranged inside the liquid storage bottle 10. The liquid shortage state detection device 92 is a reed switch. The reed switch is arranged on the side wall of the accommodating cavity 11 of the liquid storage bottle near its bottom. The reed switch is electrically connected to the liquid extraction pump 2, and the reed switch controls the start and stop of the liquid extraction pump 2.

[0180] The user places the liquid storage bottle 10 in the accommodating cavity 11 of the liquid storage bottle. If there is liquid in the liquid storage bottle 10, the magnetic float floats on the liquid surface, the magnetic float is far away from the reed switch, the reed switch sends a signal indicating no liquid shortage, and the liquid shortage state detection device 92 turns on the power supply of the liquid extraction pump 2.

[0181] If the liquid storage bottle 10 is short of liquid, the magnetic float approaches the reed switch, the reed switch sends a signal indicating liquid shortage, and the liquid shortage state detection device 92 cuts off the power supply of the liquid extraction pump 2.

[0182] The switch 91 is a microswitch. The microswitch is arranged in the housing 1 and is located above the slider 83. The pressing part of the microswitch faces the slider 83;

[0183] When the liquid guiding module 4 moves upward, the slider 83 touches the microswitch to open the microswitch, and the liquid extraction pump 2 works. When the liquid guiding module 4 moves downward, the slider 83 moves away from the microswitch to close the microswitch, and the liquid extraction pump 2 stops working.

[0184] Therefore, the start and stop of the liquid extraction pump 2 are jointly controlled by the liquid shortage state detection device 92 and the switch 91.

[0185] The above-mentioned Embodiment 3 and Embodiment 4 only list one combination situation. In other embodiments, there are also other combination schemes to realize that the start and stop of the liquid extraction pump 2 are jointly controlled by the liquid shortage state detection device 92 and the switch 91.
