In an embodiment of the present invention, referring to fig. 1, the present invention provides an intelligent hand washing method, including the following steps:
s1: monitoring the state of a user before the faucet;
s2: judging whether a user needs to wash hands or not; yes, go to S3; otherwise, go to S1;
s3: controlling to extrude the hand sanitizer adaptive to the skin of a user;
s4: and controlling to open the faucet, and starting washing hands by the user.
In this embodiment, the monitoring unit is started to start monitoring the state of a user in front of the faucet, if the user in front of the faucet is monitored, whether the user needs to wash hands is continuously judged, whether the user needs to wash hands depends on whether the infrared signals of the hands of the user exist or not, and if the infrared signals of the hands of the user are detected, the hand skin of the user starts to be detected, and whether the skin of the hand skin of the user belongs to oily skin or dry skin is detected; if the skin is oily, the control unit extrudes the hand sanitizer adaptive to the oily skin, and then the control unit controls to open the water faucet, so that the user starts to wash hands.
Further, referring to fig. 2, before monitoring the user status of the faucet in step S1, the method further includes the following steps:
s10: the face recognition unit recognizes a picture of the face of the user in front of the faucet.
Based on the embodiment, in the embodiment, before the condition state of the user in front of the faucet is monitored, the face recognition unit can be controlled to recognize the face photo of the user in front of the faucet, and the recognized face photo of the user is uploaded to the server; the server stores the recognized face picture.
Further, referring to fig. 3, step S1, after monitoring the user status in front of the faucet, the method further includes the following steps:
s11: reporting the monitored state of the user in front of the faucet to a server;
s12: the server stores the user status.
Based on the above embodiment, in this embodiment, after the monitoring unit detects the user state before the faucet, the monitored user state before the faucet is reported to the server; the user state before the faucet comprises two states of a user before the faucet and a user without before the faucet; after the server stores the user state, a corresponding command can be sent to the control system to control the faucet to be opened or closed.
Further, referring to fig. 4, step S2: judging whether a user needs to wash hands or not, comprising the following steps:
s21: controlling an infrared detection unit on the faucet to start working;
s22: an infrared detection unit on the faucet judges whether an infrared signal of a human hand is detected or not; yes, go to S23; otherwise, go to S24;
s23: users need to wash hands;
s24: no user needs to wash his hands.
Based on the above embodiment, in this embodiment, it is determined whether a user needs to wash hands, the infrared detection unit on the faucet is controlled to start working, the infrared detection unit determines whether an infrared signal of a hand of a human body is detected, and if the infrared signal of the hand of the human body is detected, it is proved that the user needs to wash hands; if no infrared signal is detected from the human hand, it is verified that no user needs to wash his hands.
Further, referring to fig. 5, in step S3: before the hand sanitizer which is adaptive to the skin of a user is extruded, the method further comprises the following steps:
s30: a skin detection unit detects the skin of the hand of the user;
s31: uploading the detection result to a server;
s32: the server makes one-to-one correspondence between the face recognition result and the skin detection result to generate a face photo-skin mapping library.
Based on the above embodiments, in the present embodiment, before controlling to squeeze out the hand sanitizer adapted to the skin of the user, the skin detection unit is to detect the skin of the hand of the user, where the skin of the hand includes oily, dry and neutral skin; meanwhile, the detection result is uploaded to a server, the server enables the face recognition result and the skin detection result to correspond to each other one by one, a face photo-skin mapping library is generated, the step of detecting the skin of the hand of the user again is omitted before the user washes the hands conveniently next time, the skin detection result corresponding to the user can be searched from the face photo-skin mapping library after the face recognition unit successfully recognizes the face, for example, if the detection result of Zhang III is oily skin, the hand washing liquid which is suitable for oil is extruded from Zhang III correspondingly for Zhang III hand washing; and before Zhang III washes hands next time, after the face recognition unit recognizes the face of Zhang III, the Zhang III is directly found out from the face photo-skin mapping library to belong to the oily skin, and the hand washing liquid which is suitable for the oily skin is directly extruded for the Zhang III.
Further, referring to fig. 6, step S4: controlling to open the faucet, and starting hand washing by a user, wherein the method comprises the following steps:

s42: controlling to open the faucet, starting washing hands by a user, judging whether the preset opening time is reached, and if so, entering S43; otherwise, go to S44;
s43: controlling to close the water faucet;
s44: no treatment is done.
Based on the above embodiment, in this embodiment, the faucet is controlled to be turned on, the user starts washing hands, the faucet turning-on time is set, for example, the turning-on time is set to 30 seconds, the user starts washing hands after the faucet is controlled to be turned on, the timer counts down the time, the faucet is controlled to be turned off after the 30 seconds, and if the time does not reach, the user does not perform processing, and the faucet is continuously turned on.
Further, referring to fig. 7, step S4: after the user starts washing hands, the method also comprises the following steps:
s401: the server counts the number of times of washing hands of the user corresponding to each face photo every day;
s402: and generating a user hygiene habit table and sending recommendation information to the intelligent terminal of the user.
Based on the embodiment, in the embodiment, the faucet is controlled to be opened, after the user starts washing hands, the server counts the number of times of washing hands of the user each day corresponding to each face photo, then generates the user hygiene habit table according to the counted number of times of washing hands, and sends recommendation information to the intelligent terminal of the user. For example, if the server counts that the number of times of washing hands for three days is 2, the user hygiene habit table generated for three days is general hygiene. If the plum four washes hands 10 times a day, the user hygiene habit table generated for the plum four is hygiene.
