Description

Feeding bottle with quick cooling and heat storage and preservation functions

Technical Field

The invention relates to the field of milk bottles, in particular to a milk bottle with functions of rapid cooling, heat storage and heat preservation.

Background

The frequency of taking milk powder by infants is high, and the structure of nutritional ingredients such as protein, vitamins and the like can be damaged due to repeated heating after milk powder is brewed, so that the brewed milk powder is not suitable for long-time storage, and the infants need to be frequently brewed with the milk powder. The suitable temperature for the baby to eat the milk powder is about 37 ℃, the temperature of the water in the household vacuum bottle is usually over 90 ℃, and in order to reduce the temperature, cold water showering and other modes are usually adopted, but the traditional method has low cooling efficiency, is inconvenient to operate and has difficult temperature control. Meanwhile, the milk powder is cooled down to a lower temperature and then is cooled down quickly in the process of feeding the baby, so that the milk powder is not suitable for drinking any more.

The existing milk bottle has the technical defects that: 1. when the infant is soaked with the milk powder, the initial water temperature is high, the cooling speed is slow, and the waiting time of the infant is too long; 2. the temperature of the brewed milk powder is difficult to maintain in the process of drinking by the infant, or the milk powder is cooled too fast due to the lack of heat preservation measures.

Furthermore, the upper part of the glass liner and the upper part of the energy storage jacket are both in threaded connection with the connecting flange.

Still further, the feeding bottle also comprises a heat-insulating cover, the lower end of the heat-insulating cover is connected with the bottle opening, and the upper end of the heat-insulating cover is connected with the lower end of the bottle cap.

Preferably, the lower end of the heat-preservation cover is in threaded connection with the upper end of the glass liner, and the upper end of the heat-preservation cover is in threaded connection with the lower end of the bottle cap.

The inner side of the energy storage jacket is made of metal, and rib plates which are used for heat conduction and support are uniformly distributed on the energy storage jacket along the bottle body and are vertical to the bottle body; the outer side is made of heat-insulating plastic, the inner metal inner wall of the inner side is packaged through hot drawing forming, and a cavity between the metal inner wall and the inner metal inner wall is filled with a phase-change material based on alkane.

The heat-preservation and heat-insulation outer sleeve is a silica gel heat-insulation material and has better heat-preservation performance.

The nipple is food level silica gel material, and the cooperation bottle lid is sealed to the feeding bottle, is equipped with the handle on the bottle lid for baby's gripping.

The technical conception of the invention is as follows: the phase change material is a substance which changes the state of a substance and can provide latent heat under the condition of constant temperature, the physical state is changed, namely phase change, and the phase change process can absorb and release a large amount of heat. By utilizing the characteristics of the phase-change material, aiming at the problems, the invention designs the feeding bottle with the functions of quick cooling, heat storage and heat preservation. The phase transition temperature interval of the phase change material is matched with the suitable temperature interval for infants, the phase change material in the invention is selected from alkane-based phase change materials, such as n-eicosane, the phase transition temperature of which is 36.8 ℃, and the suitable drinking temperature of infants is generally 36-37 ℃, and the temperature can be quickly reduced to and maintained in the suitable drinking temperature range through the phase transition process.

When milk powder is brewed, the heat of liquid with overhigh temperature in the inner container is transferred into the energy storage outer sleeve filled with the phase change material through the inner container, the phase change material in the outer sleeve is quickly liquefied by heat absorption, so that the liquid temperature of the inner container is quickly reduced, and the heat conduction contact area and the heat conduction speed are increased by the metal rib plates; when the temperature of the milk powder in the milk bottle is reduced in the process of drinking the milk powder by a baby and within a period of time, the phase-change material is solidified and conducts heat back to the inner container through the heat conduction material and the metal sheet, so that the cooling speed of the milk powder is reduced, and the temperature of the milk powder is maintained to be stable in a proper range. Meanwhile, the heat insulation jacket on the outermost side isolates heat inside the milk bottle, heat loss is avoided, and the milk bottle is used for reversely transferring the temperature to the milk powder in the inner container when the milk powder is cooled, so that the temperature stability is maintained. The infant milk powder brewing device has the advantages that the requirement of rapid cooling when the infant is brewed with the milk powder is met, the instant requirement of infant drinking is guaranteed, the milk powder is kept warm for a long time in a period of time after the infant drinking, the milk powder is maintained in a temperature range suitable for the infant drinking, and the rapidity and the drinkable time of the brewed milk powder are increased.

The invention has the following beneficial effects: the express cooling and heat preservation functions are effectively realized.
