The used electrolytic salt water flows back to the channel, passes through the filter screen 170 and flows to the second detection electrode 720, the second detection electrode 720 detects the pH value of the returned salt water to generate a second detection signal, a ratio (V0/V1) is made between the first voltage value V0 of the first detection signal and the second voltage value V1 of the second detection signal, when V1 is smaller, the ratio of V0/V1 is larger, so that the relative degree of the bacteria content in the hands is higher, and a red indicator lamp on the display panel 110 is turned on. The larger V1, the smaller the ratio V0/V1, indicating a relatively low level of hand bacteria, and the green indicator light on the display panel 110 is illuminated.
When external input alternating current and user need carry out hand cleaning and disinfection, put into first infrared receiving component 210 and the common response region of second infrared receiving component 220 with the hand, in order to generate second trigger signal, start electrolysis mechanism 300 and delivery pump 610, firstly, electrolysis mechanism 300 carries out the electrolysis to salt solution, first detection electrode 710 detects in order to generate first detection signal to the pH value of salt solution before spraying, delivery pump 610 absorbs the salt solution that has electrolyzed, the compression passes through adjustable shower nozzle, produce the spray form of slope, spray to the tiny filth of hand, play the effect of disinfecting and playing the hand washing promptly. The acquisition and indication of the bacteria content information can be similar to the treatment mode when direct current is input externally and the user needs to clean and disinfect hands, and the details are not repeated.
When the user only needs to disinfect the hands, the hands are placed in the sensing area which is only the first infrared receiving assembly 210 to generate the first trigger signal, the electrolysis mechanism 300 and the ultrasonic oscillation mechanism 400 are started, and the ultrasonic oscillation mechanism 400 breaks up the electrolyzed salt solution into mist to disinfect the hands of the user.
When the number of times of hand washing and disinfection is equal to 10, in order to keep the effective chlorine in the electrolytic salt water in the water tank stable, electrolysis is continued for 5min to reach the saturation value of HCLO, so as to achieve the purposes of saving water and controlling the size of the water tank. When the number of times of washing hands exceeds 20 times, the water tank can be changed for water and added with salt.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
