Disposable sanitary products are characterized by the ability to rapidly absorb liquids (e.g., urine, menses) to provide comfortable care to the user. The disposable sanitary product has higher requirements on the dryness of the surface layer.

At present, the dryness and smoothness of the surface layer of the disposable sanitary product are usually detected in a manual detection mode. Taking a paper diaper (the way of manually detecting the dryness of the surface layers of the pull-up diaper and the sanitary towel is the same as that of the paper diaper, and is not repeated here) as an example, usually, colored liquid simulating human urine is poured into the position, corresponding to the crotch of a human body, of the paper diaper, and the paper diaper is simulated to absorb the liquid; and observing data such as the size of an extending area of the colored liquid on the diaper, the absorption speed and the like by naked eyes, and manually recording. After the paper diaper absorbs the colored liquid, the water absorption paper is arranged in the colored liquid absorption area on the paper diaper, the weight is arranged on the water absorption paper and stands for a period of time, then the water absorption paper is taken out and weighed, and if the more colored liquid is absorbed by the water absorption paper, the poorer the dryness of the paper diaper is. The manual detection mode has the disadvantages of troublesome operation and low efficiency, and the accuracy varies from person to person.

The first embodiment,

Referring to fig. 1, 2 and 3, the present embodiment provides an intelligent disposable hygienic article detecting system, which includes a humidity detecting device 1 and a main control circuit 2.

The humidity detection device 1 comprises a first mounting plate 1, a liquid injection pipe 13 arranged on the first mounting plate 1 and used for injecting liquid (the liquid simulates human urine, the resistance of the liquid is large, and the liquid has weak conductivity), a plurality of mounting pipes 11 arranged on the lower surface of the first mounting plate 1 at intervals, and a plurality of humidity detection probes 12 arranged inside the mounting pipes 11 in a one-to-one correspondence manner.

A first electrode 14 and a second electrode 15 are arranged in the liquid injection pipe 13; a gap is left between the first electrode 14 and the second electrode 15. When the disposable hygienic article 100 is filled with the liquid through the liquid inlet tube 13, the first electrode 14 and the second electrode 15 are electrically connected, but when the first electrode 14 and the second electrode 15 are electrically connected, the liquid has a large resistance, and thus, a short circuit is not caused.

The humidity detection probe 12 is axially slidable along the pipe inside the mounting tube 11. More specifically: when in use, the humidity detection device 1 is arranged on the disposable sanitary product 100 to be detected, and the humidity detection probe 12 in the installation tube 11 freely falls and contacts the disposable sanitary product 100 under the action of gravity; when the disposable hygienic article 100 absorbs the liquid and swells, the different regions of the disposable hygienic article 100 are formed to have different thicknesses due to different water absorption amounts, and the humidity detection probes 12 are pushed up to different positions, so that the humidity detection probes 12 can always be in contact with the surfaces of the different regions of the disposable hygienic article 100 even if the different regions of the disposable hygienic article 100 have different thicknesses. Each of the humidity detecting probes 12 is used for detecting a humidity value of each area of the disposable hygienic article 100 to determine dryness of the surface of different areas of the disposable hygienic article 100.

When liquid is injected into the liquid injection pipe 13, the first electrode 14 and the second electrode 15 in the liquid injection pipe 13 are conducted, and the microprocessor 20 starts timing; the humidity detection probes 12 detect the humidity values of the various regions of the disposable hygienic article 100 to determine the dryness of the surface of the disposable hygienic article 100, and can be transmitted to an upper computer (not shown) through the communication interface module 22. The timing is terminated until the value of the humidity detected by each humidity detecting probe 12 becomes stable, thereby calculating the liquid absorption rate of the disposable hygienic article 100.
