Abstract

The utility model relates to a urine alarming device with simple structure, good sensitivity and small size, which is composed of an alarming device, a urine probe and connecting leads, wherein the alarming device adopts the existing music circuit board, and the urine probe is a small printed circuit board. Two electrodes of the printed circuit board adopt E-shaped penetrating type bilateral structure; the two electrodes of the urine probe are respectively connected to an input interface of the alarming device by the two leads. When the utility model is used, the urine probe is coated in the urine wetting place to be detected in a diaper, and the alarming device is clamped on an infant's body far from the urine probe. When the diaper is wetted by urine, the two electrodes of the probe are cut to the short circuit by urine, the alarming device is switched on, and then, the alarming musical sound is sent out. Compared with the existing urine alarming device, the utility model has the advantages of small probe size, light weight, high sensitivity, small size and low cost, and needs not the special design. When the utility model is in alarming, the sound volume is not high; by adopting the music for alarming, the utility model is interesting.

Description

Urine-wet alarm device

Technical field

The utility model relates to the electrical application technology field, particularly a kind of urine-wet alarm device.

Background technology

In actual life, solving the urinate most popular method of problem of baby is to adopt more changing babies' napkin method, no matter be disposable diaper might as well, reusable diaper might as well, all need to the mat for baby diaper, just change after urine is wet.Diaper is urinated wet back as untimely replacing and following problem is arranged: 1, wet diaper makes the baby catch a cold easily, even sick.2, that fast asleep baby is frozen is awake for wet diaper, influence sleep, 3, wet diaper can enlarge wet cloth scope, involves clothes, doss etc.Therefore, preferably can in time change wet diaper.For can be in time changing babies' napkin more, the problem that solve is timely discovery " urine is wet ".As wait until that yell for baby reports to the police, that is just too late.

Someone has invented the electronics urine-wet alarm device, realizes urine-wet alarm with the wet method of popping one's head in of electronic alarm device+urine, makes people can in time know " urine is wet ".

The subject matter of existing urine-wet alarm device is that the wet probe size of urine is too big, complex structure, carry and use have too convenient.

Summary of the invention

The purpose of this utility model is a kind of simple in structure, sensitivity good, volume is little urine-wet alarm device of design.

The utility model can be realized by following scheme: a kind of urine-wet alarm device, form by alarm, the wet probe of urine and connection lead.

Described alarm can adopt ready-made music circuit plate, and this music circuit plate is usually used on the birthday card;

The wet probe of described urine is a little printed circuit board (PCB), is divided into two electrodes on this printed circuit board (PCB), for increasing sensitivity, two electrodes adopt E shape cross-linking structure, the design of more saying a step is that this little printed circuit board (PCB) adopts two-sided design, and promptly pros and cons has two roughly the same electrode structures

To urinate the input interface that wet the two poles of the earth of popping one's head in are connected respectively to alarm with two leads, lead should have suitable length, generally should be greater than 20cm.

During use, the wet probe of urine contained will survey the wet place of urine in diaper, alarm away from the wet probe of urine, and is become entrained on one's body the baby, the standing up of baby waited action that urine is wet to pop one's head in and extracted.

When urine was wet, two electrodes of probe were connected alarm by the urine short circuit, send the alarm sound music immediately.

With existing urine-wet alarm device contrast, probe size of the present utility model is little, and is light, highly sensitive; Alarm need not particular design, and volume is little, and cost is low.During warning, volume is little, and adopts music alarm, has interest.

The drawing explanation

Fig. 1 is a structural representation of the present utility model.

Embodiment

Urine-wet alarm device as shown in Figure 1 is made up of alarm 2, the wet probe 1 of urine and connection lead 3.

Described alarm 2 is made of ready-made music circuit plate+plastic casing, and built-in button cell has a power switch 21 to expose shell, and can adopt does not have the Auto-delay switch of switch music circuit plate yet.

The wet probe 1 of described urine is a little printed circuit board (PCB), is divided into two electrodes 11 and 12, two electrodes on this printed circuit board (PCB) and adopts the relative cross-linking structure of E shape, and this little printed circuit board (PCB) 1 adopts two-sided design, and its back side has two roughly the same as shown electrode structures.

The two poles of the earth 11 and 12 that to urinate wet probe 1 with two leads 3 are connected respectively to the input interface of alarm, and the length of lead is greater than 25cm.

During use, the wet probe 1 of urine contained in diaper, will survey the wet place of urine, alarm 2 away from the wet probe 1 of urine, and is become entrained on one's body the baby.

When urine was wet, two electrodes 11 and 12 of probe 1 were connected alarm 2 by the urine short circuit, send the alarm sound music immediately.

Claims

1. a urine-wet alarm device is made up of alarm, the wet probe of urine and connection lead, it is characterized in that:

The wet probe of described urine is a little printed circuit board (PCB), and this printed circuit board (PCB) has two electrodes, will urinate the input interface that wet two electrodes of popping one's head in are connected respectively to alarm with two leads,

2. urine-wet alarm device according to claim 1 is characterized in that: two electrodes of the wet probe of urine adopt E shape cross-linking structure.

3. urine-wet alarm device according to claim 1 and 2 is characterized in that: the printed circuit board (PCB) of the wet probe of urine adopts two-sided design, and promptly pros and cons has two roughly the same electrode structures.

4. urine-wet alarm device according to claim 1 is characterized in that: the length that connects alarm and the wet lead of popping one's head in of urine is greater than 20cm.
