Description

Music electronic napkin

This utility model relates to a kind of music alarm diaper by electronic circuit control.Baby's diaper must often be changed keeping baby's a home from home, but owing to do not know when defecation of baby, often changes untimely.The diaper that a kind of being called " diaper " arranged on the market when using this diaper, when the baby has urine, goes below can stream being seeped into, and guarantees that the baby can have more comfortable dry environment, if but the baby has had stool, and then not fluence being seeped into gone below the diaper.

This utility model purpose provide a kind of to baby stool, urine can both report to the police and type of alarm for playing music to remind the baby head of a family, baby's diaper is wet, should change carriage of clean diapers.

This utility model is achieved in that it is made up of combination cloth A and electronic circuit, makes up cloth A by cloth A ₁, A ₂Form, two plain conductor L are housed in its interlayer ₁, L ₂, this two lead can be sewn in the interlayer this two lead and two end points P that are sewn on one jiao of place of combination cloth A ₁, P ₂Lower Half P ₁₁, P ₂₁Link; Two lead K that draw from electronic circuit B ₁, K ₂Respectively with two lead L that make up cloth A ₁, L ₂Connection end point P ₁, P ₂Become dismountable connection, electronic circuit B is by housing M and be contained in its inner thyratron transistor D, audion BG, musical film KD, piezoelectric ceramics Y, speaker S, resistance R ₁, R ₂, power supply E and draw lead K ₁, K ₂Form.The base stage of audion BG and lead K ₂And resistance R ₁Link the anode 3 of colelctor electrode and thyratron transistor D, lead K ₁And the positive pole of power supply E links emitter stage and resistance R ₂And the control utmost point 1 of thyratron transistor D links to each other, and the negative electrode 2 of thyratron transistor D links to each other with 7 with the end points 4 of musical film KD, and the end points 6 of musical film KD and end points 5 link end points 5 and the resistance R of musical film KD with piezoelectric ceramics Y parallel with one another and two ends of speaker S respectively ₁, R ₂The other end all link with the negative pole of power supply E.Its working method is the conducting by audion BG control thyratron transistor, thereby has controlled the work of musical film KD and piezoelectric ceramics Y and speaker S.Lead L among the combination cloth A when diaper is dry ₁, L ₂Not conducting, then lead K ₁, K ₂Yet not conducting, audion BG and thyratron transistor D do not work, and speaker S is not worked, when the baby will make up cloth A urine when wet, two lead L among the combination cloth A ₁, L ₂Conduction is with lead K ₁, K ₂And resistance R ₁Circuit is connected, and makes audion BG conduction, in resistance R ₂Last generation trigger voltage is controlled this thyratron transistor D conducting, controls this musical film KD, piezoelectric ceramic piece Y and speaker S work by thyratron transistor D, sends melodious music, reminds the head of a family to note, the diaper that should renew.The contact point P of combination cloth A and electronic circuit B ₁, P ₂Be dismountable device, can be two groups of double buckles or pin socket structure, its Lower Half P ₁₁, P ₂₁Be fixed on the cloth A of combination cloth A ₁On, its first half P ₁₂, P ₂₂With lead K ₁, K ₂Be fixed together, when wet diaper need change again the time, with detachable apparatus P ₁, P ₂Throw off, can change clean.

This utility model is simple in structure, and cost is lower, and electronic devices and components are to be bought on the market easily, and wet diaper the time, can in time notify the head of a family more changing babies' napkin with melodious music.

Do concrete introduction with embodiment below, Fig. 1 is an outline drawing of the present utility model, and Fig. 2 is an electrical schematic diagram.

Make up cloth A as shown in fig. 1 and include cloth A ₁, A ₂Two-layer, cloth A ₁, A ₂In the interlayer, sew up two plain conductor L that are parallel to each other ₁, L ₂, the one end be fixed on cloth A ₁On double buckle P ₁, P ₂Lower Half P ₁₁, P ₂₁Link cloth A ₁, A ₂And lead L ₁, L ₂All sew the lead K that draws from electronic circuit B with line F ₁, K ₂The end be fixed on double buckle P ₁, P ₂First half P ₁₂, P ₂₂The place, when using with double buckle P ₁, P ₂Upper and lower two and half button dead, lead L then ₁, L ₂With lead K ₁, K ₂Communicate.Combination cloth A is placed on below baby's health, electronic circuit B from the baby in one's infancy through lead K ₁, K ₂Draw, be placed on the infanette, when diaper is when doing, lead K ₁, K ₂Not conducting, audion BG and thyratron transistor D do not work, and after baby's defecation, cause the diaper humidity, lead L ₁And L ₂Between conducting, then lead K ₁, K ₂Conducting.As shown in Figure 2, as lead K ₁, K ₂Between contact resistance when reaching certain numerical value, audion BG work is in resistance R ₂Last formation one trigger voltage makes thyratron transistor D conducting, works to musical film KD energized, makes speaker S work by piezoelectric ceramics Y amplification, plays out melodious music, and the head of a family in time is baby's changing babies' napkin to remind.
