Description
Technical field
The utility model relates to a kind of diaper automatic alarm circuit, belongs to electron and electrician technical field.
Background technology
Diaper, as a kind of daily living article of infant, because it is simple, practical, and enjoys the head of a family to favor.But because infant is young, physiological development is incomplete, and its stool and urine is irregular, often easily occurs to change diaper in time because the head of a family does not have the stool and urine behavior of Timeliness coverage child and cause that infant's is uncomfortable.Therefore, for above background, the utility model proposes a kind of diaper autoalarm, it effectively for the irregular situation of infant's stool and urine, can carry out automatic alarm in time, avoids causing that infant's is uncomfortable.
Summary of the invention
The technical problems to be solved in the utility model is: the utility model provides a kind of diaper automatic alarm circuit, it is mainly for the irregular situation of infant's stool and urine, by design physical circuit, realize auto-alarm function, the head of a family that can wake up in time changes diaper, thus it is uncomfortable to effectively prevent the infant caused because failing to change diaper in time.
Technical solutions of the utility model are: a kind of diaper automatic alarm circuit, comprise resistance R1, R2, electric capacity C1, C2, interrupteur SW 1, SW2, exploring electrode A, B, power supply terminal Uo, hummer LS, 555 timer TS, relay R L, power supply BAT;
7 pins of described 555 timer TS are connected with one end of resistance R1, R2; Be connected with one end of interrupteur SW 1 again after the other end of described resistance R1 is connected with 4,8 pins of 555 timer TS respectively; The other end of described interrupteur SW 1 is connected with power supply terminal Uo; Be connected with one end of electric capacity C2 after the other end of described resistance R2 is connected with 2,6 pins of 555 timer TS; The other end of described electric capacity C2 is connected with exploring electrode A; Described exploring electrode B ground connection; The 1 pin ground connection of described 555 timer TS; 5 pins of described 555 timer TS are connected with electric capacity C1 one end; The other end ground connection of described electric capacity C1; Described 3 pins of 555 timer TS are connected with 1 pin of relay R L; The 2 pin ground connection of described relay R L; 5 pins of described relay R L are connected with one end of interrupteur SW 2; The other end of described interrupteur SW 2 is connected with the negative pole of power supply BAT; 3 pins of described relay R L are connected with one end of hummer LS; The other end of described hummer LS is connected with the positive pole of power supply BAT.
The course of work of the present utility model is: Closing Switch SW1, SW2, and plant-grid connection is in circuit; When diaper is dampness, conducting between exploring electrode A, B, electric capacity C2 charges, and 555 timer TS export high level, relay R L conducting adhesive, and hummer LS gives the alarm and reports to the police; When diaper is drying regime, open circuit between exploring electrode A, B, 555 timer TS output low levels, relay R L is in off-state, hummer LS place circuit breaker, and hummer LS quits work;
Circuit working principle of the present utility model is: described 555 timer TS, by being connected with resistance R1, R2, electric capacity C1, C2, ground terminal GND, interrupteur SW 1, power supply terminal Uo, exploring electrode A, B, constitute a multivibrator; Conducting between exploring electrode A, B, electric capacity C2 charges, and 555 timer TS export high level, are in attracting state after relay R L conducting, and hummer LS conducting sounding the alarm; Separated as exploring electrode A, B, the multivibrator formed stops oscillation, and relay R L disconnects, hummer LS place circuit breaker, and stops sounding the alarm;
The beneficial effects of the utility model are: the utility model is irregular for infant's stool and urine, and the head of a family because fail Timeliness coverage child stool and urine behavior and diaper could not be changed in time and cause this problem uncomfortable of infant, by design physical circuit, finally achieve the auto-alarm function for infant's diaper, thus effectively improve the quality of life of infant, and simultaneously for the head of a family alleviates certain life stress.The utility model cost is low, use is simple, practical, is suitable for extensive popularization.
