Background technique
Existing paper diaper general structure is simple, has a single function, only has basic function.It is developed rapidly in wearable device
Today, paper diaper need to add new function for it, to help parent as unique with infant " standing equipment "
Preferably look after baby.
It after paper diaper are urinated wet, needs to replace in time, otherwise buttocks is easy to generate cotton-padded mattress because being chronically at humid tropical condition
Sore and rotten skin, influence infantile health.In addition, the body temperature of infant it should also be appreciated that, when the symptoms such as low fever occurs in infant
When, it is also desirable to monitoring and prompting are made in advance, in order to avoid delay treatment.
But guardian can not keep within 24 hours infant at one's side, just check paper diaper every a bit of time
Whether have urine it is wet, even daytime, when also having busy once in a while, sometimes can carelessness forget look after infant.Therefore,
It needs to design a kind of intelligent monitoring device, alarm is triggered after infant urinates and defecates or when body temperature varies widely, remind prison
Shield people pays attention to.In addition, if frequent charge can be very troublesome, thus the design of low-power consumption is very necessary since 24 hours work.

Specific embodiment
The utility model is described in detail with embodiment with reference to the accompanying drawings.
As shown in Fig. 1 ~ 7, a kind of intelligent paper diaper with sound prompt function, including 1 ontology of paper diaper, further include
Detector;1 ontology of paper diaper is equipped with two wet sensitive variable resistance bands 2;The detector includes plastic shell and is deployed in it
Internal circuit system;The plastic shell includes the rear shell 4 being flexibly connected and front housing 6, and plastic shell is equipped with locking device,
The locking device includes the locking press button 5 for being deployed in 6 outside of front housing and the switch 7 for being deployed in 4 outside of rear shell;Front housing 6 it is interior
Side is equipped with two groups of resistance contact points 9, and the inside of rear shell 4 position corresponding with two groups of resistance contact points 9 is equipped with an insulation spacer
10;The middle part in 6 outside of front housing is additionally provided with thermal contacts 8, and battery compartment 3 and indicator light are additionally provided on front housing 6;In the battery compartment 3
Button cell for powering for circuit system is installed;It include master controller, master controller connection temperature in the circuit system
Spend sensor, voltage amplifier, indicator light, bluetooth module;The input terminal of the temperature sensor connects thermal contacts 8, voltage
The differential input end of amplifier is separately connected two wet sensitive variable resistance bands 2, and wet sensitive variable resistance band 2 is connected to knob after connecting with divider resistance
Detain the positive and negative end of battery;Data transmission channel is established between the bluetooth module and smart phone.
The length of two wet sensitive variable resistances band 2 is consistent, and spacing is uniformly and width is 1cm, and wet sensitive variable resistance band 2 is urinated from paper
The position of trousers 1 edge close to navel is extended to close to anus position.
The thermal contacts 8 and resistance contact point 9 are stainless steel material.
The quantity of two groups of thermal contacts 8 is four.
The gasket 10 is electro-insulating rubber material.
The application method of the utility model are as follows:
It is put into button cell in a detector first.
Then the switch 7 on Pen-down detection device, locking press button 5 pop up, and plastic shell is opened, later will be wet on paper diaper 1
The end of quick variable resistance band 2 is clipped between front housing 6 and rear shell 4, wherein the corresponding side close to infant's body in the position of front housing 6,
Two groups of resistance contact points 9 are pressed respectively against on two wet sensitive variable resistance bands 2.Resistance between two wet sensitive variable resistance bands 2 can change with humidity,
Under low humidity, impedance is megohm grade, and as humidity increases, the resistance between two wet sensitive variable resistance bands 2 reduces.Paper diaper 1 are
Multilayered structure, the surface layer that wet sensitive variable resistance band 2 only has marginal portion to be exposed to paper diaper 1, rest part are respectively positioned in paper diaper 1
Layer.Locking press button 5 is pressed, detector is made to keep clamped condition.Since gasket 10 is elastic insulated material, therefore front housing 6 and rear shell 4
After clamping, resistance contact point 9 and gasket 10 tightly clamp wet sensitive variable resistance band 2, are not easy to loosen.
Grip plastic shell moment, indicator light fast blink 3 times, every time lasting 500ms, for prompting user, this inspection
Device is surveyed to have worked normally.Detector after normal work, bluetooth module are opened, and guardian is (general by the smart phone of oneself
All have Bluetooth function) it is matched with detector, to establish data transmission channel.
Paper diaper 1 are put on to infant, at this point, detector is attached near infant's navel, thermal contacts are attached to abdomen skin
On skin, so that the temperature of thermal contacts is consistent with the shell temperature of infant.Temperature sensor is every the primary temperature of acquisition in 10 seconds
Degree value is used as the body temperature value reference of infant.As continuously measured the temperature value beyond normal range (NR), master controller three times
Body temperature alarm signal is issued to the mobile phone matched with it by bluetooth module, mobile phone plays voice prompting guardian and pays attention to.
When not having to urinate l Water Paper urine pants, impedance is very big between two wet sensitive variable resistance bands 2, thus the electricity at voltage amplifier both ends
Crimp the voltage of nearly button cell.ADC module inside master controller detects the voltage value of voltage amplifier output end, and with
Standard value compares, and master controller judges that paper diaper are not urinated wet at this time.Conversely, after paper diaper are urinated wet, two wet sensitives
Resistance value between variable resistance band 2 can reduce with hydrouria, so that the voltage at voltage amplifier both ends can become smaller.When being less than
When certain numerical value, that is, think that urine volume is more, needs to handle in time.And urine volume reaches a certain level, wet sensitive variable resistance band 2 reaches or connects
The variation of nearly saturation, resistance is maximum, thinks that urine volume is enough at this time, it is necessary to replace paper diaper 1.Master controller passes through bluetooth
Module issues prompting message to the mobile phone of pairing.Include the judgement to wet degree is urinated in prompting message.The detection of ADC module every
It executes once within 10 seconds, to can not only find rapidly when urinating wet, but also unnecessary power supply waste can be reduced.
After mobile phone receives prompting message, analysis judgment can be carried out to information coding.If the content of prompting message is " slight
Urinate wet ", guardian needs to pacify infant;If the content of prompting message is " moderate urine is wet " or " severe urine is wet ",
Guardian needs replacing paper diaper and wipes to the body of infant.Above situation, mobile phone, which passes through, plays different sounds
Frequently, remind guardian note that the audio is the voice prerecorded.
After detector long-time use, electricity can decline or even be reduced to the degree not being available, and need replacing battery.This
When extract battery compartment 3, take out old button cell, be changed to new.
