Background technology
In the time of the feeding baby milk powder, milk powder to reconstitute consumption temperature very big to the health effect of infant.Milk is overheated, can cause infant to be scalded; And milk is cool excessively, can cause infantile diarrhea again.The tradition feeding bottle can't be learnt a bottle interior temperature of liquid, causes the adult generally to take hands to touch the examination gentleness when giving Infantile nursing and tries methods such as temperature personally.These method accuracys and wholesomeness are all very poor, because the adult has very big-difference with infant to the sensitivity and the fitness of temperature, and the intraoral pathogenic bacteria of adult and antibacterial all can be caused the pollution to beverage in the feeding bottle.
Although have a lot of feeding bottle thermometric patented technologies and much transformed production, but still have a lot of defectives.Mainly show following several respects: temperature sensor places a bottle wall outside thermometric, makes temperature-measuring results not accurate enough; Paste temperature sensing material in the bottle outside, the temperature-measuring results error is bigger; Temperature sensor directly contacts with milk, but does not have warning function, the convenience that influence is used.
The same with temperature, the humidity of air is healthy closely bound up with the child also.Humidity is too high, causes the undue growth of some antibacterial easily; And humidity is low excessively, and the air overdrying then can cause infant skin too dry, even causes the generation of encephalitis B.Therefore, temperature and humidity is to influence infantile health modal two big factors, on the other hand, because the used humistor critesistor used with measuring temperature of electronic surveying humidity has the characteristics of matching on operation principle, therefore, the two can be compatible with in an IC chip and the circuit board, thereby the product price ratio is greatly improved, product cost greatly reduces.
The utility model content
The purpose of this utility model is to provide a kind of bottle side wall temperature display hygrometric feeding bottle with the adjustable temperature warning function, can overcome on the basis of feeding bottle thermometry shortcoming in the past, thermometric and hygrometric technology are organically blended, simple in structure, esy to use, safe and reliable.
The purpose of this utility model is achieved in that a kind of temperature display hygrometric feeding bottle, it comprises feeding bottle and electronic temperature measurement hygrostat two parts, wherein feeding bottle comprises nipple, bottle cap and bottle, it is characterized in that: at the sidewall of body, the electronic temperature measurement hygrostat that connects interior temperature of liquid of a display bottle and air humidity, this electronic temperature measurement hygrostat comprises housing, intelligent temperature measurement hygrometric circuit, temperature sensor, humidity sensor, be provided with circuit control panel and display screen at housing, described temperature sensor embeds bottle, and described humidity sensor contacts with air.
In order to make the safety feeding bottle have the temperature and humidity prompting function, this electronic temperature measurement device also comprises the humiture alarm set, this humiture alarm set is loudspeaker, buzzer, light emitting diode or electromagnetic shaker, comprises the humiture alert circuit in the intelligent temperature measurement hygrometric circuit.User can be set by the circuit control panel and remind temperature or remind humidity, when the milk liquid temp becomes when reminding temperature and air humidity to reach to remind humidity, alert circuit starts alarm set and produces alerting signal, can play beautiful music as loudspeaker, light emitting diode can produce the light of different colours, and electromagnetic shaker can also allow bottle shake.
This utility model also comprises dust cover, the annulus of this oriented inner bulge in dust cover end opening edge, the outer big ledge structure of the little lower outer diameter of top external diameter that is with of described bottle cap, lower end part at little external diameter has annular recess, when covering dust cover, its end opening edge annulus of projection to the inside embeds in the annular recess of bottle cap.This structure can make the dust cover fastening at the feeding bottle loam cake, and the height of described dust cover is a little less than the height of nipple, and dust cover is pushed down the nipple opening part slightly.Bottle interior liquid is inverted in bottle slight inclination or moment, and liquid that can not flows out in the bottle.
This utility model also comprises portable handle, and this portable handle is made up of the handle of a middle collar and both sides, is provided with annular projection in the bottleneck bottom, and the collar of portable handle embeds and is fixed in the annular projection of bottleneck bottom.The inboard of described portable handle two side handles has projection, and it can improve feel, increases frictional force, difficult drop-off in use.
Described electronic temperature measurement hygrostat has heat dissipation ventilation hole and connecting device on it.Heat and steam that this structural design is produced when helping distributing thermometric hygrometric circuit working make the electronic temperature measurement hygrostat closely link to each other with bottle.
The core component of critesistor as the thermometric degree adopted in described temperature sensor, described critesistor is selected NTC critesistor (being negative tempperature coefficient thermistor) for use, its resistance value of negative tempperature coefficient thermistor is along with the rising of NTC critesistor body temperature presents reducing of step evolution, temperature is high more, and resistance value is more little.Because the resistance of thermal resistor changes with variation of temperature, microprocessor just can be converted into temperature value with the resistance variations numerical value that records and be shown by LCDs.
Described humidity sensor adopts the core component of humistor as the hygrometric degree, and described humistor shallow one deck macromolecule humidity-sensitive film of having penetrated on a special dielectric base forms.When airborne water vapor adsorption was on humidity-sensitive film, the resistivity and the resistance value of element all changed, and microprocessor is converted into humidity value with the resistance variations numerical value that records and outputs on the liquid crystal display.
This utility model compared with prior art has following advantage:
At first, described thermometric hygrometric device possesses the thermometric temperature display simultaneously and hygrometric shows wet two big critical functions, a compatible shared cover electronic system, this product is possessed simultaneously measure the function that shows that milk liquid temp, air themperature, air humidity and temperature humidity are reported to the police, compare the product of realizing above function separately respectively, the resource that it consumed significantly reduces, and cost reduces greatly, has brought real material benefit to consumer.
Secondly, temperature sensor embeds bottle, guarantees the thermometric accuracy.
Once more, described electronic temperature measurement hygrostat, use intelligent temperature measurement hygrometric circuit and humiture alarm set, on the housing of sidewall, be provided with circuit control panel and temperature and humidity display, by control panel the numerical value of reminding temperature and humidity can be set, display screen can show the milk real-time temperature and remind temperature value, also can show air humidity and remind humidity value.Described humiture alarm set can be loudspeaker, buzzer, light emitting diode or electromagnetic shaker.When the milk liquid temp becomes the prompting temperature, can play beautiful music as loudspeaker, light emitting diode can produce the light of different colours, and electromagnetic shaker can also allow bottle shake.
At last, bottle and Electronic temperature display hygrostat housing are reasonable in design, and good looking appearance is easy to use, safe and reliable, are a kind of ideal temperature display hygrometric feeding bottles.
