Below in conjunction with accompanying drawing, most preferred embodiment of the present utility model is described in further detail.

Fig. 1 shows urine body alarm electrical principle block diagram.Testing circuit links to each other with control circuit, and control circuit links to each other with warning circuit, connects the warning circuit power supply by control circuit again, produces alarm sound.

Fig. 2 is a urine body alarm electrical schematic diagram.1,2 is two bare metal wires by suitable distance row example among the figure, and after repeatedly complications were arranged, on the attached cloth pad that is fixed in 12cm * 32cm, this had just formed testing circuit.1, No. 2 lines are connected to b, the c utmost point of T1 respectively arbitrarily.T1 selects NPN type germanium tube (Vceo is less) for use, and its e, the c utmost point connect battery E2 and E1 respectively.T1 is operated in and ends or saturated two kinds of states, is control circuit.

Newspaper device circuit is mainly by vocal music sheet KD-152M and loud-speaker (HA) with report device display lamp (HL) to form.

When the baby urinated body, urine was infiltrated on the cloth pad of 1, No. 2 line, because of urine is a conductor, then produced b, the c utmost point that an equivalent resistance is added on T1 between 1, No. 2 line, and T1 becomes saturation conduction because of obtaining base current by ending.The T1 conducting, then E1, E2 just superpose and are added to warning vocal music sheet KD-152M, the work of vocal music sheet, (HL) is bright for display lamp, and loudspeaker (HA) ring.Tell the guardian that the baby has urinated body, so that timely changing babies' napkin more.
