Abstract

Milk bottle is one just to be brought and can eat, and eat how many overabundant heat less by electricity heating, and the automatic constant-temperature baby drinks the bottle that milk is drunk water and drunk other liquid.Volume had electrical heating wire around this milk neck part had a central canal, gave the milk heating of central canal inside, and the milk that the baby will be eaten is heated when flowing through this pipe, and a side of central canal has the thermal sensitive piece of pair of lamina metal to regulate the open close of electric current.

Description

Milk bottle

The invention belongs to the dairy industry category.

The temperature that nourishes the baby on mother's milk is suitable.Nutritious growth promoter to the baby is ideal, but because a variety of causes, the breastfeeding rate of China is very low at present.The breast feeding of China cities and towns on average has only 33% according to the statistics made by the departments concerned, and this ratio of big city is just low more, the baby breastfeeding rate in Shanghai City only 15%, all the other are all by artificial feeding milk, because milk must be fed after boiling, just there is a temperature problem in this, and rule of thumb, this temperature is approximately 38-55 ℃.Temperature is low, and the baby easily suffers from gastroenteropathy.The temperature height then easily scald, this temperature is difficult to realize and keep in reality is fed.Its former because, 1, the infant feeding interlude is short, often,, can go on crying as can not get timely nursing when thirsty hungry, 2, because baby's strength is little, often one bottle of milk just has been able to eat a bit and has been fallen asleep with regard to not interesting.But wait his milk of having a rest when recovering strength and will eat cool again, 3, the baby often also will eat once milk at dead of night, parents at this moment sleep just fragrantly, and get up suddenly and boil milk is very arduous thing, moreover the baby also can wait impatiently.The importance that feeds the baby with milk as can be seen and heat at this point.Occurred a kind of feeding bottle electric warmer in the market, it can continue well-done milk to remain on an edible temperature, but there is two important shortcomings.First this feeding bottle will be suckled and will be kept at a higher temperature for a long time, will become yoghourt or degenerate after this milk soon.The secondth, the time of children's's suckling is longer, under the colder situation of weather, and the feeding bottle of taking out in the thermophore, child just has been able to eat a period of time and has just cooled off, and children's can not continue to drink.Therefore press for a kind of Convenient feeding bottle in the market.

The objective of the invention is: produce a kind of feeding bottle very easily, just bring when the baby need suck the breast and eat, the temperature of being sucked the breast is that children's is optimum, and the part of avoiding children's not eat heats for a long time or repeatedly and milk is degenerated very soon or becomes yoghourt.This is the purpose of milk bottle.

The scheme that the technology of the present invention solves is: it is cervical region at feeding bottle that this feeding bottle is given the key position of milk heating and automatic constant-temperature, at the cervical region of feeding bottle and the centre of big lid one thin and long pipeline is arranged, this pipe both can be a metal, it also can be other material of heat conduction, this pipe around around electrical heating wire, its water back and ducted milk have the bimetallic strip of a temperature-sensitive on the next door of heater strip.This sheet metal can be crooked along with the friendshipization of temperature, above thermal sensitive piece, be with elastic copper sheet, the upper end of copper sheet links to each other with the electrical heating wire upper end, its underpart contacts with thermal sensitive piece, the gap of contact is subjected to the control of a screw, just the distance that can regulate this contact gap by set screw, thereby the temperature of regulating central canal are because the homoiothermic precision of this milk heating is very low.The temperature friendshipization is at 38-55 ℃, so reach thermoregulated purpose fully by this device, the lower end of electrical heating wire and thermal sensitive piece is drawn by lead respectively, and connects a plug, there is a throttling film top of centre pipe, and its perforate can be satisfied the flow velocity that children's's finding is inhaled.And the time that milk is arrheaed in heating tube is long to guarantee the enough temperatures of acquisition of suckling.At the pipeline that an air inlet is arranged first of milk bottle cap, its inside can be inserted an elongated plastic tube and be arrived the bottle end, inflates in bottle.

Advantage of the present invention: the present invention is that what to take is heating while eating, and what are eaten, and what the structure of heating has following advantage, 1, heats soon, be to heat, can give child's suckling at any time when child will eat, 2, that the temperature constant of heating needn't be worried is supercool overheated while eating.3, the present invention is that child eats what the structure of how much heating, and repeats heating with regard to the part of avoiding the baby not eat like this or at high-temperature point constant temperature, and just making suckles unlikelyly becomes yoghourt or degenerate.Just can see the significant values of this feeding bottle when weather is colder from this point, and it is also extremely valuable in hot day, as the new fresh milk of buying can be put into cold preservation in the cold room of refrigerator after boiling the feeding bottle of packing into, the prolongation fresh keeping time can in time eat again.

Fig. 1 is a structural representation of the present invention.

Be further described with regard to the present invention below in conjunction with accompanying drawing:

(1) pacify, (2) top tegillum, (3) choked flow film, (4) homoiothermic copper sheet, (5) set screw, (6) thermal sensitive piece, (7) heating tube, (8) electrical heating wire, (9) air inlet pipe, (10) milk bottle cap, (11) rubber-insulated wire, (12) nursing bottle body, (14) plug.

The alternating current that domestic are 220 volts becomes low-voltage AC or the unidirectional current harmless to the people after transformation, or other low-tension supply harmless to the people, and process lead (11) is guided to the cervical region of feeding bottle, an end in contact of one end and electrical heating wire (8).The upper end of heating wire (8) with regulate copper sheet (4) and contact, the other end of lead is connected with temperature regulating piece (6), the upper end of temperature regulating piece contacts with copper sheet, the contact gap of copper sheet (4) and adjustment sheet (6) be subjected to screw (5) thus control can attemperation.Copper sheet (4) and thermal sensitive piece contact when the temperature around the electrical heating wire is low, and heater strip conducting heating becomes suitable temperature by low temperature when milk is flowed through central canal (7).There is a choked flow film (3) central canal (7) top, and the perforate above it is much smaller than the caliber (7) of central canal, so milk is heated milk at the flow velocity of central canal slowly fully, effusive milk portion is covered the air of equivalent by air inlet pipe (9).When temperature rise during to certain scope thermal sensitive piece (6) disconnect with regulating copper sheet owing to the different upper surface outside curve that make it of the thermal coefficient of expansion of bimetallic strip, circuit disconnects, heating stops.Obtain constant temperature.The heating power that electricity adds silk is bigger, can guarantee that milk also can obtain corresponding heat when the flow velocity of central canal is very fast.This feeding bottle adopts a center tube structure, also can adopt number to follow pipe, pipe is with being filled with conduction material in the middle of the pipe, the present invention adopts the heating wire heating, also can adopt critesistor heating or Muscovitum heating, the temperature-sensitive backing of this feeding bottle can be a straight plate shape up and down, it also can be the circular shape of contour central canal, electric heating device of the present invention and temperature sensor structure both can be in the outsides of central lumen, also can give milk direct heating and constant temperature in the inside of central lumen, the film that choked flow film of the present invention was both with holes also can be a plate with holes.
