Among them, a first installation hole and a second installation hole are opened at the bottom of the extension part 200. The first installation hole and the second installation hole are on the same horizontal line. One side of the first installation hole is the outer wall of the housing 100, and the other side of the first installation hole is the second installation hole. The nozzle 300 is installed in the second installation hole, and the infrared induction module 310 is installed in the first installation hole. The liquid pumping module is arranged inside the housing 100, and the liquid pumping module is respectively connected to the liquid storage box and the nozzle 300.

The power supply is respectively connected to the control chip U1, the infrared induction module 310, the liquid pumping module, and the indication module.

[0031] It should be noted that when the infrared induction module 310 senses a user, it will send a corresponding level signal to the control chip U1. After receiving the corresponding level signal, the control chip U1 controls the liquid pumping module to pump the soap liquid in the liquid storage box to the nozzle 300, and then sprays it out from the nozzle 300.

[0032] It should be noted that by installing the nozzle 300 in the second installation hole and the infrared induction module 310 in the first installation hole, it can be ensured that when the infrared induction module 310 recognizes a user, the user's hand is below the nozzle 300, avoiding the soap liquid from spilling and improving the user experience.

[0033] It should be noted that an observation slot 400 for observing the liquid storage box is provided on the side wall of the housing 100, and the user can directly understand the content of the soap liquid in the liquid storage box through the observation slot 400.

[0034] It can be understood that the indication module includes two light-emitting diodes connected in parallel, and the light-emitting diodes are connected to the control chip U1. The control chip U1 can send different signals to make the light-emitting diodes emit different colors or blink at different frequencies. For example, the lights can be turned on according to different working states of the intelligent soap dispenser.
