Description

Paper diaper capable of judging stool and urine

Technical Field

The invention belongs to the field of sanitary articles, and particularly relates to a paper diaper capable of judging excrement.

Background

At present, although the paper diaper sold in the market can absorb urine, the paper diaper can not be replaced by reminding people in time, the paper diaper is not replaced after the baby defecates, the buttock skin of the baby can be swollen or allergic due to the long-time contact of the defecate, and the body of the baby is damaged. In order to replace polluted paper diapers in time, people develop various paper diapers with the function of reminding urination and defecation, and in the schemes, urine is judged by means of a temperature sensor and a humidity sensor, and excrement is judged by adopting an odor sensor; the technical scheme is high in cost because a high-precision single chip microcomputer needs to be matched for measurement and monitoring, and although some schemes replace the sensor with the resistance tape, the cost is still high; sensors as key components, such as a humidity sensor and a humidity-sensitive resistor temperature sensor, are easily polluted and corroded due to the fact that the sensors need to be in contact with excrement and urine, although the temperature sensor and the excrement and urine are isolated by a single scheme and are placed on the outer side of the diaper, the temperature sensor and the humidity sensor for the diaper are large in size due to requirements on precision and implementation mode, and the diaper provided with the temperature sensor and the humidity sensor brings inconvenience to the use of a baby; in addition, in the prior art, the sensor monitors electrical parameters such as resistivity, and potential safety hazards of electric leakage can be caused when the sensor contacts urine and urine.

Disclosure of Invention
