AI Technical Summary
When the high-temperature milk liquid expands, it is easy to cause high pressure in the bottle. The milk liquid pours into the pacifier through the return valve and sprays it out, causing safety hazards such as choking or scalding in infants and young children.
Add two one-way exhaust valves to the pacifier. When the air pressure in the bottle increases, the high-pressure gas is discharged through the gap between the one-way exhaust valve and the tooth ring to stabilize the air pressure in the bottle and prevent milk spraying.
It effectively prevents the spray of milk, ensures the safety of infants and young children, and has a simple structure and low production cost.

Abstract

Technical Field
[0001] The utility model relates to the technical field of feeding bottles, in particular to an anti-spray feeding bottle. Background Technique
[0002] Most of the feeding bottles on the current market have the following problems: When the gas generated by the high-temperature milk liquid in the feeding bottle expands and causes high pressure inside the bottle, the milk liquid will rush upward into the nipple cavity through the liquid delivery tube of the air return valve. After the nipple cavity is filled with milk liquid, due to the air pressure inside the feeding bottle still being higher than the external air pressure, under the action of high pressure, the milk liquid will spray out from the nipple hole, which is the milk spraying phenomenon. This situation often causes unsafe hazards such as infants choking on milk or being scalded. There is also another situation that when the feeding bottle is vibrated or shaken, the milk liquid in the feeding bottle will occasionally spray out, resulting in poor consumer experience.
[0003] CN217793835U discloses a duckbill feeding bottle for preventing water spraying, which includes a duckbill-shaped nipple and a feeding bottle, and the two are detachably connected. Two arc-shaped diaphragm pieces are symmetrically arranged inside the mouth of the duckbill-shaped nipple, and the cross-section of the two arc-shaped diaphragm pieces in the height direction is V-shaped to close the mouth; each arc-shaped diaphragm piece includes an arc-shaped edge and a straight edge, the arc-shaped edge is connected to the half-circular inner wall of the mouth, and a reinforcing rib is arranged at the lower end of the two straight edges, and a gap for liquid diversion is opened on the reinforcing rib. The duckbill feeding bottle of the utility model uses two arc-shaped diaphragm pieces combined into a V shape to close the mouth of the duckbill-shaped nipple, and because the reinforcing rib is set to have a certain gravity suppression on the gap for backflow, when the liquid is sucked, the liquid is sucked out, avoiding fluid waste and hot water spraying out to scald and wet the user, and can ensure the personal safety of the user. However, the structure of this anti-spray feeding bottle is relatively complex and the production cost is relatively high. Therefore, we propose an anti-spray feeding bottle with a simple structure. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an anti-spray feeding bottle. Two one-way exhaust valves are added to the nipple. When the air pressure inside the bottle is generated by the gas of the hot liquid or the high pressure inside the bottle is caused by shaking, the generated high-pressure gas is discharged outside the bottle under the action of the two one-way exhaust valves and the gap between the tooth ring and the nipple, forming a stable air pressure inside the bottle and not causing the milk spraying phenomenon, which can effectively solve the problems in the background technique.
[0005] To achieve the above object, the utility model provides the following technical solution: An anti-spray feeding bottle includes a bottle body and a one-way valve assembly; a tooth ring is connected to the upper side of the bottle body by a thread, the tooth ring is of a sleeve-like structure and arc-shaped grips are symmetrically arranged on both sides, a nipple is sleeved on the upper end of the tooth ring, a one-way valve assembly is arranged on the upper part of the nipple, and a straw is snap-connected to the inside.
[0006] The one-way valve assembly includes a one-way intake valve and two one-way exhaust valves. The one-way intake valve and the one-way exhaust valves are at different heights, and the one-way intake valve is located higher than the one-way exhaust valves.
[0007] Furthermore, the two one-way exhaust valves are at the same height and on the same circumference. The angle formed by the centers of the two one-way exhaust valves and the center of the circle is not less than 90°, so that the exhaust gas spreads out.
[0008] Furthermore, the inner side of the connection between the one-way exhaust valve and the nipple is a depression, and the one-way exhaust valve is located at the bottom of the depression.
[0009] Furthermore, a part of the one-way intake valve protrudes from the nipple.
[0010] Furthermore, a snap ring is provided at the inner bottom of the nipple part of the nipple. The snap ring includes a downwardly extending sleeve and a circular ring. The bottom of the sleeve is integrally formed with the outer circular edge of the circular ring and is adapted to the snap ring. A straw plug is provided at the top of the straw. The straw plug is a hollow cylinder. One end of the straw passes through the straw plug. An annular groove is provided on the outer side of the cylinder, and the bottom is a funnel-shaped structure. The annular groove is snap-connected to the circular ring part of the snap ring.
[0011] Furthermore, a gravity ball is provided at the bottom of the straw. The straw passes through the gravity ball, and the weight of the gravity ball is used to keep the straw always at the bottom.
[0012] Furthermore, the gravity ball is a spherical body or a cylinder.

The position of the one-way air inlet valve 21 is higher than that of the one-way exhaust valves 22. When hot water is added or the milk bottle is heated, the air expands due to heat, the air pressure rises, and the gas is discharged outside the bottle under the action of the two one-way exhaust valves 22 and the gap between the tooth ring 3 and the nipple 2, forming a stable air pressure inside the bottle and preventing the milk spraying phenomenon.
[0025] Among them, the two one-way exhaust valves 22 are at the same height and are on the same circumference. The included angle formed by the centers of the two one-way exhaust valves 22 and the center of the circle is not less than 90°, so that the exhaust is diffused; the inner side of the connection between the one-way exhaust valve 22 and the nipple 2 is a depression, and the one-way exhaust valve 22 is located at the bottom of the depression; a part of the one-way air inlet valve 21 protrudes from the nipple 2 inside.
