Abstract

The utility model belongs to an acoustic-optic wet detector, used for detecting the stool and pee of a baby or a patient, composed of a box body, a line conductor and a sensor. The inner part of the box body is provided with batteries and a sonification integrated block, and the sensor is composed of a clip that has contacts and a piece of paper sheet that is dipped by electrolyte. The utility model has the advantages of novel and unique structure, simple and safe control circuit, and good effect on wet detection, suitable for babies or patients that can not handle the own stool and pee, so that a plurality of troubles can be omitted.

Description

The acousto-optic hygrostat

This utility model belongs to a kind of the articles for daily use, is mainly used in just detection alarm of baby, patient-sized.

Infant and some severe cases, defecation can not be taken care of oneself, particularly infant, if can not in time find whether defecation of child, and timely changing babies' napkin more, will the be urinated and defecated hardship of dipping of child, if can often open baby's infancy winter, be easy to make child to suffer from cold.

The purpose of this utility model is a kind of hygrometric device of being reported to the police by acousto-optic hint of design, and this installs below the diaper that an end is placed on detected object, and the other end is placed on the detected person by the side of, reports to the police with prompting.

This utility model as shown in Figure 1, its structure is that an end is sensor (5), the other end is a box structure, the centre has a lead (4) to connect; Battery (7), pronunciation integrated package (8) are installed in the box body (1), and on and off switch (3), display lamp (2) are installed on the box body shell; The composition of control circuit is such, and display lamp (2) and pronunciation integrated package (8) back in parallel is connected in series in both ends of power with sensor (5); Sensor (5) is made up of with the impregnated scraps of paper of electrolyte clip and a slice of a contact-carrying.The quality of considering the electrolyte of use and the scraps of paper is different, also a normally opened contact of pronunciation integrated package can be parallel on the sensor (5), when the moment that sensor is subjected to wet energising, normally opened contact closure, the electric conductivity of entire circuit be can strengthen, thereby the susceptiveness and the reliability of hygrostat strengthened.

Usage of the present utility model and operation principle are: will clip with the scraps of paper that electrolyte treatment is crossed with the clip on the sensor, be put under baby's the diaper, the box body of control section is placed on the baby by the side of, open the on and off switch on the box body, when the baby large and small just the time, urine is soaked the scraps of paper, because of the scraps of paper are crossed with electrolyte treatment, so after soaking, can conduct electricity, thereby the turning circuit display lamp is lighted, the pronunciation of pronunciation integrated package is reported to the police, and at this moment can will be changed by the wetted scraps of paper, relays scraps of paper and gets final product.

The utility model has the advantages that: novel structure, uniqueness, control circuit is simple and safe, and the hygrometric effect is fine, is used for the patient that infant or defecation can not be taken care of oneself, and can save the many troubles of mother and ward.
