Abstract

The utility model relates to a urinating wet alarm which is composed of a urinating wet probe, a music chip, a buzzing sheet and an electric source, clamped and sealed in transparent composite plastic sheets capable of hot gluing. The utility model which provides an alarm with simple circuit, easy use and low cost can be used for reminding guardians to replace wet napkins for babies or patients in time at night.

Description

Ultra-thin type urinating wet alarm

The utility model belongs to a kind of warning instrument to conducting liquid (as urine etc.) sensing contact.

The feature of similar instrument shows mostly have following characteristics in to China's utility model patent according to the retrieval: the one, except that CMOS large scale integrated circuit Music Clip, also all used to promoting repeating circuit and the element that output element work is introduced.This makes that the entire circuit structure is the most terse not enough.The 2nd, the volume of instrument itself is microminiaturized not enough.The 3rd, the sonde configuration design is succinct not enough.The 4th, electronic component all is fixed on the substrate and then is fixed in the capsule.The 5th, the trigger action mode that adopts no longer continues to report to the police after having played a song usually, and night, the head of a family of fatigue may bent not crying wake up.

It is simpler and effective that the purpose of this utility model provides a kind of circuit, and outward appearance is more microminiaturized or claim the instrument of the novel conductive liquid sensing contact of ultrathin typeization, thereby uses lighter and handier convenience, and cost is also lower.

The purpose of this utility model also be to provide volume suitable and guarantee that being in night grows into and sleep after can in time be alerted the warning instrument of the wet diaper of changing baby (or patient).

The purpose of this utility model is achieved in that utilizes CMOS large scale integrated circuit Music Clip can be designed to the suitable characteristics that directly promote output element ┈ buzzing sheet, and directly simply the buzzing sheet in toot chamber and small dry battery and the wet probe of urine and shell are formed altogether by this Music Clip and band.Such array mode makes circuit reduction arrive bottom line, has also reduced cost.

The purpose of this utility model also will realize like this: the shank of warning instrument is not to be installed in the box but with the transparent composite plastics sheet ┈ of the material ┈ hot pressing bonding of similar certificate plastic packaging cover main part to be packaged into the shape of a thin slice, thereby has saved before the utility model the substrate of fixed electronic element in the technology.Elevational thickness also drops to bottom line, has also reached microminiaturized and light and handy purpose easily.

The purpose of this utility model also will realize like this: Music Clip is connected with the buzzing sheet in the mode of direct promotion buzzing sheet, this makes after as long as the head of a family is placed on bedside to audible segment of the present utility model, and volume enough can get up to change baby's wet diaper and unlikelyly influence the baby owing to volume is too loud and other people sleep peacefully when song is played in warning the night prompting head of a family.The form work that the Music Clip triggering mode of the utility model employing is simultaneously selected level triggers especially for use, this makes the utility model can guarantee to play bent the warning continuously always before diaper is not replaced, till the head of a family of fatigue is waken and change wet diaper.

Be further described below in conjunction with accompanying drawing:

Fig. 1 is circuit theory diagrams of the present utility model

Buzzing sheet b directly is connected on the output terminal of Music Clip a.The wet probe of urine d directly is connected on the level triggers end of Music Clip a.Power supply c is that the little shape dry cell (as No. 5 or No. 7) of 1.5 volts at a joint directly is connected on the power supply end points of Music Clip a.

Fig. 2 is the stereographic map of probe d of the present utility model

Fig. 3 is the sectional view of probe d of the present utility model

The wet probe of urine d is made of transparent composite plastics sheet (2) and (3) of lead (1) and hot pressing bonding.Lead (1) as Fig. 2, shown in Figure 3 walking, and behind the interlayer that enters plastic sheet (2), (3), is peelled off insulated hull and is exposed core in plastic sheet (2).The spacing of two leads (1) is less than 2mm, and parallel arrangement as shown in Figure 2.After lead (1) has been arranged as Fig. 2, Fig. 3, make (2), (3) bonding with the method for hot pressing, walk wherein lead core simultaneously also by sealing.

Fig. 4 is an overall picture stereographic map of the present utility model

E is two layers of transparent composite plastic thin slice of hot pressing bonding.The original paper that will connect by Fig. 1 mode is after the interlayer of e is put in the position as shown in Figure 4, with the oblique line part thermo-compression bonding shown in Fig. 4, battery c is fixed by the holding force of plastic tab nature like this, but can take out replacing again simultaneously, and element a, b also are fixed on wherein.F is that an aperture hangs usefulness for threading.

The utility model has following advantage than prior art:

1. specific triggering mode has avoided once playing the deficiency that Qu Keneng is the tired head of a family that do not wake up.

2. circuit is simpler and can work effectively equally than prior art.

3. the design of sonde configuration is more simple and reliable than prior art.Because it is it is a plastic film,, safer to the baby compared with using the fiberglass substrate in the prior art.

Thereby so 4. since the possibility that circuit structure simply breaks down also to drop to minimum more durable.

5. owing to the form that has adopted the plastic tab encapsulation, so saved the substrate that is used as retaining element in the preceding technology of the utility model.Shell of the present utility model had both played the effect of outer package, had also played the effect of fixing internal electronic component simultaneously.Come compared with the technology before the utility model, thickness is littler, and cost is lower, and light and handy, moves easy to use.

Best implementation of the present utility model is to fold up at diaper probe of the present utility model d at first in the interlayer at moist position.All the other partly or put or hang over bedside.When probe touches urine, the sounding of the bedside partly graceful melody of existing moderate volume is played warning.Alarm condition is till wet diaper is changed.When probe leaves wet environment, promptly get back to and treat duty.

Claims

1, a kind of ultrathin urine-wet alarm device, this ultrathin urine-wet alarm device directly are made up of a Music Clip a and the piezo b of a band resonator and a batteries c and the wet probe of the urine d that draws of clamp in the transparent composite plastics sheet e of hot pressing bonding.

2, by the described ultrathin urine-wet alarm device of claim 1, it is characterized in that shell selected the bonding transparent composite plastics sheet of hot pressing for use, after the seal be the shell of instrument played again can geometrical clamp electronic component therein effect.
