Abstract

The invention relates to a baby bed-wetting reminding mat. A plurality of humidity sensors are connected in parallel and fixed on a plastic thin board or a hard paperboard; the plastic thin board or the hard paperboard is inserted in a matched cotton mat; when a baby wets a bed in the event of sleeping on the baby bed-wetting reminding mat, the baby bed-wetting reminding mat can instantly send out music only when any one humidity sensor is triggered by a humidity signal, therefore, the baby bed-wetting reminding mat can remind parents to change a diaper; after being wetted, the baby bed-wetting reminding mat can also be continuously sleeved in another spare cotton mat after the sensors are dried; the cotton mat can be cleaned and dried; and the baby bed-wetting reminding mat is comfortable and convenient to use.

Description

The baby wets the bed and reminds pad

Technical field

The present invention relates to the alarm set that a kind of baby of being used for wets the bed, belong to electronic information field.

Background technology

The device that has many babies of being used for to wet the bed and remind at present is after humidity sensor is put in baby's diaper lower floor and opens switch, during infant sleep; With diaper pad below hip; The baby is after urinating on the diaper, if the position that diaper is soaked by urine is positioned at the top of humidity sensor just, reminiscences can be reminded more changing babies' napkin of father and mother with music immediately; If the position that diaper is soaked by urine is not the top that is positioned at humidity sensor; Though promptly the baby wets the bed, the diaper position that is positioned at directly over the humidity sensor remains dried, and prompting music that then should the bed-wetting alarm set can not sounded.The mode that most reminiscences adopts sensor and baby' diaper directly to contact when design because the material of sensor is harder, can influence the comfort level of baby sleep.Meanwhile; Because general bed-wetting alarm set induction position single (humidity sensor); Induction point (humidity sensor) placement location is difficult to confirm; Be easy to cause the failing to report of reminiscences (though promptly wet the bed, owing to be not the diaper at position directly over the humidity sensor, so that the alarm set of wetting the bed does not ring).This makes reminiscences to remind father and mother like clockwork, makes father and mother still have worry.

Summary of the invention

Single in order to overcome the existing baby reminiscences induction position of wetting the bed; Placement location is unfixing; And use problems such as uncomfortable; The present invention provides a kind of baby to wet the bed to remind pad, the characteristics of this promptings pad to be to adopt multiple spot to respond to (a plurality of humidity sensors are parallelly connected) and a plurality of humidity sensors position relative fixed; Baby provided by the invention wets the bed and reminds pad mainly to be made up of 13 parts) the humidity sensor fixed head, fixing above 5 (or n; N is a positive integer) individual humidity sensor, the cotton pad of (2) openings parallel with one another between the humidity sensor, an end of opening can seal with zip or clasp; Be easy to open or seal, 3) signal processing circuit, battery; Electron device and enclosure; After any one humidity sensor was triggered by moisture signal, signal processing apparatus can drive loudspeaker and send musical sound, in time was more changing babies' napkin of child with the head of a family who reminds the nurse child.Humidity sensor places cotton pad inner together with fixed head during use, and the baby can directly lie on the face pad, or on the face pad, puts diaper, has improved the comfort level and the level of comfort degree that use; After cotton simultaneously pad quilt urine was wet, sensor can take out from the cotton pad easily, and was simple to operate, was convenient to the cotton pad of cleaning or replacing.

The technical solution adopted for the present invention to solve the technical problems is: with 5 (or n; N is a positive integer) hygristor of identical or different model places respectively on the sheet plastic of an about A4 paper size; This plate is the humidity sensor fixed head hereinafter referred to as, and the material of humidity sensor fixed head also can be the cardboard of waterproof, and the size of humidity sensor fixed head can be to be fit to the sleep arbitrary dimension of mat of child; Such as 50x50cm, 40x50cm or the like.When humidity sensor was 5, the fixed position was each one at center and four jiaos and with lead they is connected in parallel.When the humidity sensor that uses is other numbers outside 5, humidity sensor is evenly distributed on the humidity sensor fixed head.During use sheet plastic is placed and the supporting cotton pad of its size, the position of the corresponding hygristor of cotton pad does not contain cotton-wool, only stays one deck to approach cloth (gauze or face), is convenient to the induction of hygristor to hydrone.After the baby wet the bed, hygristor was met the hydrone resistance and is reduced, no matter be that one of them or several hygristor resistance change, the all-in resistance after the parallel connection was reduced.Control section adopts comparer to control the broadcast of music, and when being in drying regime, the positive input terminal voltage of comparer is higher than negative input end, output low level; After hygristor chance hydrone resistance reduced, the positive input terminal voltage of comparer was higher than negative input end voltage, and the output high level triggers the music triode and sends music, adds adjustable resistance in the music circuit, and the feasible I that gives great volume is adjusted by the user.

The invention has the beneficial effects as follows that can directly sleep baby in this invention of baby wets the bed and reminds on the pad or appoint and so under baby's hip, fill up diaper, and is easy to use; The induction of employing multiple spot has reduced and has failed to report what the baby wet the bed; The wet the bed cotton pad part of reminding pad of the baby of this invention can be easily wet the bed with the baby of this invention and is reminded other parts (humidity sensor and the humidity sensor fixed head that fills up; Signal processing circuit, battery, loudspeaker and enclosure) separate; Unpick and wash conveniently, can be recycled.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is further specified.

Fig. 1 is circuit theory diagrams of the present invention.

Fig. 2 is the floor map of cotton pad.

1. sheet plastics among Fig. 1,2,3,4,5,6. hygristor, 7. comparer, 8. music triode and loudspeaker.

1. cotton pads among Fig. 2,2,3,4,5,6. hygristor correspondence position.

Embodiment

In Fig. 1, hygristor (2-6) parallel connection places on the sheet plastic (1), inserts comparer (7) circuit, carries out voltage ratio and connects music triode and loudspeaker (8) in the back, the broadcast and the shutoff of control music.

In Fig. 2, cotton pad (9) size is slightly larger than sheet plastic, makes things convenient for the insertion and the taking-up of sheet plastic; (2-6) be hygristor correspondence position on the sheet plastic; Only stay one deck to approach cloth, do not contain cotton-wool, both can satisfy the induction of hygristor hydrone; Can avoid the baby directly to contact again, improve the comfort level of using with sensor.

Claims
