Degree, positions sanitary care article to be detected.
8. it is according to claim 4 a kind of for testing and analyzing the device of sanitary care article liquid spread condition, it is special
Sign is that the humidity sensor detection module of the array includes: humidity sensor pcb board fixed plate, humidity sensor pcb board
And overlay film, the humidity sensor pcb board fixed plate are fixed on the bottom of pressure exerting arrangement, the humidity sensor pcb board is fixed
In the lower part of humidity sensor pcb board fixed plate, the overlay film is covered on the lower surface of humidity sensor pcb board.
9. it is according to claim 8 a kind of for testing and analyzing the device of sanitary care article liquid spread condition, it is special
Sign is, humidity sensor detection lug is provided on the humidity sensor pcb board, and the humidity sensor detection lug output connects
The control host is connect, array square hole is provided on the overlay film, array square hole is used to make the humidity on humidity sensor pcb board
Sensor detection lug is preferably contacted with the surface of sanitary care article to be detected.
10. a kind of spread feelings for testing and analyzing sanitary care article liquid based on any one of claim 1-9 described device
The method of condition, which is characterized in that described method includes following steps:
Step 1: sanitary care article to be detected is placed on core detection module；
Step 2: pressure exerting arrangement drives surface layer detection module to move downward, sanitary care article to be detected is contacted, it is pre- until reaching
If pressure when stop and keep；
Step 3: liquid of the liquid injection mechanism to the injection point of sanitary care article to be detected injection set amount；
Step 4: being transmitted to control host when core detection module detects the liquid of diffusion, controls and shown in real time on host display
Show liquid in the intracorporal diffusion position of sanitary care article core to be detected；
Step 5: being transmitted to control host when surface layer detection module detects the liquid of diffusion, control host passes through real on display
When show the relative humidity of the entire surface layer difference coordinate position of sanitary care article to be detected, and then reflect that liquid is defended to be detected
The diffusion velocity on raw nursing materials surface layer；
When the relative humidity on the sanitary care article surface layer to be detected detected is greater than the humidity threshold of setting, show to detect
Liquid has begun in sanitary care article to be detected to be occurred bleeding back phenomenon.
