Preferably, the scales of the feeding bottle are marked on the outer cylinder surface of the adjusting cylinder; compare in the bottle, the size of adjusting a section of thick bamboo is less, and the scale of mark on it covers the most of adjusting a section of thick bamboo circumference, and the milk volume is observed from each angle that can be convenient, need not the scale that the rotatory feeding bottle of user observed the body to promote and use experience.
The principle and advantages of the invention are as follows:
when the feeding bottle is placed, the adjusting column slides towards the lower end of the adjusting cylinder, the adjusting liquid is pressed into each shaping pipe, the shaping pipes are deformed and stretched under pressure and are bent outwards, the bottle body protrudes outwards, the volume of the bottle body is increased, and more milk can be conveniently brewed at one time; meanwhile, water poured into the bottle body can promote the bottle body to protrude outwards, the bottle body with the protruding part has a larger caliber, the dissolving speed of milk powder can be increased after the milk powder is poured, and the brewing speed is effectively increased.
When the baby drinks, the feeding bottle is in an inverted state, the adjusting column slides towards the upper end of the adjusting cylinder at the moment, the adjusting liquid in the shaping pipe is sucked back into the adjusting cylinder, and the shaping pipe has the tendency of deformation shortening and recovery to the original long and straight state, so that the bottle body is compressed flat, and the volume of the bottle body is reduced; therefore, in the process of drinking milk by the baby, as the milk is continuously reduced, the bottle body is synchronously flattened, and the volume of the bottle body is reduced, so that the air pressure in the feeding bottle is kept balanced with the outside, the low pressure of the feeding bottle caused by the reduction of the milk is effectively avoided, the outside air is prevented from entering the feeding bottle, the generation of bubbles in the process of drinking milk is effectively prevented, and the milk choking is further avoided; when the baby drinks milk, the adjusting column slides to the lower end of the adjusting cylinder when the bottle body is placed right at the gap between the baby and the baby, at the moment, the volume of the bottle body is increased, outside air is supplemented into the bottle body in time, but milk flows back to the bottom of the bottle, and air entering the bottle body cannot generate bubbles.
In conclusion, in the process of feeding the baby with milk, the feeding bottle can not generate negative pressure, air can not enter the feeding bottle, and air bubbles can not be generated in milk, so that milk choking is effectively avoided; air is supplemented in time when the milk bottle is placed in the gap between the milk and the milk bottle, so that the air pressure in the bottle body and the outside air is kept balanced all the time, and bubbles in the milk are prevented from being generated again; therefore, the invention has good choking effect; in addition, the shape and the size of the bottle body are variable, and the feeding bottle has a smaller size when being placed upside down in an empty state, so that the feeding bottle is convenient to carry and store; because no air bubble is generated when the nipple is used, the rubber head can be provided with only one nipple, the design of an air return hole is omitted, normal air return can be met, no air bubble is generated, and the production process is greatly simplified; the opening of the air return hole is omitted, the integrity of the rubber head can be further guaranteed, cleaning and sterilization are convenient, bacteria are effectively prevented from being attached and bred at the air return hole, and the feeding bottle is healthier to use.
