As can be seen from the above, since the hand washing machine of the present embodiment employs the pump driving mechanism 1 according to the first embodiment of the present invention, the simple structure that the driving part 11 is connected with the driving device 12 can pump out liquid medium, the pumping-out mode is more convenient, the liquid outlet speed is higher, the whole structure of the hand washing machine is simpler, meanwhile, the liquid pumping module 3 is detachably arranged in the upper cavity 21 of the bin body, moreover, the liquid pumping module 3 comprises a plunger pump 31, a liquid pumping part 311 of the plunger pump 31 is detachably connected with the driving plate 112 of the liquid pumping driving mechanism 1, so that after the liquid medium of the liquid pumping module 3 is used up, the liquid outlet can be replaced and updated, so that the problem that the hand sanitizer cannot be sprayed out due to the fact that the liquid outlet is blocked when the liquid outlet is exposed to the external environment for a long time in the existing commercial hand washing machine is effectively solved, and the problem that the hand sanitizer cannot be extracted due to the fact that a liquid pumping mechanism breaks down is also solved.

Further, it is worth mentioning that, as shown in fig. 1, fig. 2 and fig. 4, since the pumping liquid module 3 has the plunger pump 31, the plunger pump 31 includes: the liquid pumping member 311 and the plunger 312 are coaxially connected, and when the driving device 12 drives the slide plate 111 to slide back and forth in the preset linear direction, the driving plate 112 drives the liquid pumping member 311 to press the plunger 312, and further, the plunger 312 presses air in the container 32, so that the liquid medium in the container 32 is extracted.

Specifically, when the encrypted information obtained by the main control module 4 is inconsistent with the encrypted information pre-stored inside, that is, it indicates that the current liquid pumping module is a counterfeit, at this time, the main control module 4 can output a first electric signal to the switch circuit, and the switch circuit disconnects the power module 6 from the motor 121 of the driving device 12 after receiving the first electric signal, so that the motor 121 cannot be powered on, and the whole liquid pumping driving mechanism 1 cannot drive the liquid pumping unit 311 of the plunger pump 31. On the contrary, when the encrypted information obtained by the main control module 4 is consistent with the encrypted information prestored inside, it is indicated that the current liquid pumping module is a genuine product, at this time, the main control module can output a second electric signal to the switch circuit, and the switch circuit electrically conducts the power module 6 with the motor 121 of the driving device 12 after receiving the first electric signal, so that when the hand washing machine needs to pump liquid, the motor 121 can be normally powered on, and the influence on the liquid pumping of the hand washing machine cannot be caused.
