[0049] The working process of this embodiment:

[0050] When people need to wash their hands and disinfect, they first wet their hands with water, and then press the pressing plate 200. The folded edge of the pressing plate 200 abuts against the pressure head and presses the pressure head downward, and the pressure head starts to spray disinfectant. The roller 132 rolls in the track 210 and drives the rack slide 310 to move downward along the sliding seat 320. The outer teeth of the rack slide 310 drive the gear shaft 140 to rotate. The ratchet groove 141 on the gear shaft 140 clamps the ratchet pawl 131 and drives the rotating shaft 138 to rotate. The rotating shaft 138 The time-sharing turntable 410 is driven to rotate. During the downward movement of the rack slide 310, the disinfectant will continue to spray out. The rotating shaft 138 drives the two time-sharing turntables 410 to rotate. The second sliding claw 139c on the rotating shaft 138 and the first sliding claw 139a on the sliding claw base 137 produce relative movement. The rotating shaft 138 drives the two time-sharing turntables 410 to rotate circumferentially and moves axially at the same time. The two time-sharing turntables 410 resist the second spring 160 and compress the second spring 160. When the limit When the screw 311 abuts the sliding seat 320, the angle of the time-sharing rotating disk 410 is half of the angle of the two adjacent contact bosses 411. At the same time, the first sliding claw 139a and the second sliding claw 139c complete a meshing movement. The contact boss 411 on one time-sharing rotating disk 410 triggers a contact switch 120, and the timing alarm 420 connected thereto emits a timing start prompt sound and starts timing. The other contact switch 120 is located on two adjacent contact bosses 411 on the other time-sharing rotating disk 410. 1 is in the middle position and has not been triggered. The pressing plate 200 is released, the pressure head rebounds, and the rack slide plate 310 moves upward driven by the pressing plate 200, while driving the gear shaft 140 to reverse. At this time, the pawl 131 cannot get stuck in the ratchet groove 141, and the rotating shaft 138 will not rotate, that is, the pressing plate 200 will not drive the time-sharing turntable 410 to rotate during the rebound process. Then, wash your hands according to the standard hand washing steps. After 3 minutes, the timing ends and the alarm rings, and then you can rinse your hands with disinfectant.
