Description

Technical Field

[0001] The utility model relates to the technical field of baby products, in particular to a pressure-stabilizing air guide component and a sucking bottle thereof. Background Art

[0002] Newborn babies, especially those aged 0-6 months, have incomplete gastrointestinal development. They are very likely to suffer from bloating and choking when drinking milk, which is particularly harmful to babies. As the baby's rice bowl, how to prevent bloating and choking in newborn milk bottles is a big issue.

[0003] When using existing newborn baby bottles, after milk powder and hot water are added into the bottle and the lid is closed, the temperature inside the bottle is higher than the temperature outside the bottle. Once the bottle is shaken or inverted, the air inside the bottle expands due to the heat, making the pressure inside the bottle higher than the pressure outside the bottle. Since there is no obstruction inside the bottle, the milk will directly flow into the nipple cavity. Under the pressure difference and the gravity of the milk itself, the milk will spray out from the nipple opening. This can easily lead to various consequences such as excessive milk flow rate at the nipple opening being too high and the baby not having time to swallow the milk, resulting in choking during feeding.

[0004] In traditional feeding bottles, an air inlet hole is opened on one side of the nipple. When the nipple is inverted to suck milk, the air inlet hole is easily covered with milk to produce milk bubbles, which makes the baby prone to spitting up milk after sucking. In addition, milk is easily retained in the air inlet hole and is not easy to clean, which makes it easy for bacteria to grow. In addition, milk is also easy to overflow from the air inlet hole, causing milk leakage. At present, there is a kind of milk bottle that can prevent leakage and choking on the market, such as a balanced pressure guide piece and a sucking bottle thereof with publication number CN222467555U. In this structure, the inner ring and the outer ring are connected to form a constant pressure channel, and the nipple is provided with an air guide hole, and the air guide pipe is arranged below the main body of the balanced pressure guide piece and is connected to the constant pressure channel so that the constant pressure channel is connected with the air guide hole of the nipple. In this embodiment, the air guide pipe is connected to the bottom of the constant pressure channel. Specifically, the bottom surface of the balanced pressure guide piece is provided with an air guide joint that communicates with the constant pressure channel, the air guide pipe is inserted into the air guide joint, and the bottom of the air guide pipe has a one-way valve port so that the air guide pipe is connected with the outside through the air guide hole. One-way valves are provided in the air tubes to prevent milk from entering the air ducts or air holes, avoid bacterial growth, and balance the internal pressure. However, since one-way valves are provided in the air holes and air tubes, the baby needs a greater suction force to ensure that the outside air enters the bottle body when sucking milk, which makes it difficult for the baby to suck milk smoothly. In addition, the ventilation effect of a single air hole and the inside of the bottle body is poor, which easily leads to an imbalance between the air pressure and the outside air pressure. If the air hole is blocked, it is easy to cause the outside air to be unable to communicate with the inside of the bottle body, thereby causing negative pressure inside the bottle body, making it difficult for the milk in the bottle body to flow out normally, and even liquid will overflow from the gap between the screw cap and the bottle opening. Utility Model Content

[0005] The technical problem to be solved by the embodiment of the utility model is to provide a pressure-stabilizing air guide and a sucking bottle thereof, which utilizes the pressure-stabilizing air guide to keep the air pressure in the bottle stable, thereby ensuring that the baby can suck milk smoothly and preventing milk from overflowing.

[0006] To achieve the above-mentioned purpose, the utility model discloses a pressure-stabilizing air-guiding component, which includes an outer ring and an inner ring. The outer ring and the inner ring are connected to form an air-guiding cavity. The inner ring is used to air-tightly cooperate with the lower opening of the nipple to form a liquid-guiding channel. The air-guiding cavity is connected to a connecting tube. An air-guiding duct is arranged between the connecting tube and the inner ring, and a groove is arranged on the top surface of the outer ring. The groove enables the air-guiding cavity and the air-guiding duct to form a first air pressure balance channel.

[0007] Furthermore, an air guide tube is sleeved on the connecting tube, and a one-way valve is provided at the lower opening of the air guide tube to prevent milk from entering the air guide tube and avoid the growth of bacteria due to poor cleaning after the milk enters the air guide tube.

[0008] Furthermore, the surface of the outer ring in contact with the opening of the bottle body is coated with sealant.

[0009] Furthermore, there are at least two air guide pipes, which are equidistantly arranged around the connecting pipe as the center, and the air guide pipes are all connected to the connecting pipe, so that the external air can circumferentially flow better with the inside of the bottle body.

[0010] Furthermore, a needle withdrawal hole is provided on the peripheral wall of the outer ring corresponding to the air guide duct, so that after the pressure-stabilizing air guide component is injection-molded, the ejector pin can be directly withdrawn from the air guide duct and filled with the sealant in the needle withdrawal hole to prevent air leakage in the air guide cavity through the needle withdrawal hole.

[0011] The utility model also provides a sucking bottle, comprising the above-mentioned pressure-stabilizing air guide member, a nipple, a bottle body, and a screw cover, wherein the nipple is installed on the opening of the bottle body through the screw cover, the pressure-stabilizing air guide member is arranged between the bottle body and the nipple, and an air guide channel communicating with the outside is formed between the groove of the pressure-stabilizing air guide member and the bottom surface of the nipple.

[0012] Furthermore, the nipple is provided with an air hole, and a ventilation one-way valve is provided at the lower end of the air hole, so that the air hole and the air guide cavity form a second air pressure balance channel.

[0013] Furthermore, the opening of the bottle body is airtightly connected to the sealant of the pressure-stabilizing air guide member, thereby preventing the milk in the bottle body from leaking out from the gap between the pressure-stabilizing air guide member and the opening, thereby greatly improving the sealing performance of the bottle body.

[0014] Furthermore, an air guide tube is provided on the connecting tube of the pressure-stabilizing air guide component, and the lower end of the air guide tube extends to the bottom surface of the bottle body, so that the lower end of the air guide tube is higher than the liquid level of the milk when the bottle is inverted to suck the milk, which can prevent the outside air from contacting the milk and generating bubbles.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) In the utility model, there are a plurality of air-conducting channels between the outer ring and the nipple that are connected to the air-conducting cavity, and in combination with a plurality of air-conducting pipes on the liquid-conducting channel that are connected to the air-conducting cavity, so that the bottle body can be connected to the outside world through a plurality of air-conducting pipes, the air flow is better, thereby greatly reducing the suction force of sucking, so that the baby can suck the milk more smoothly, and at the same time avoid blockage that causes the outside air to be unable to communicate with the inside of the bottle body, thereby ensuring that the air pressure in the bottle is always kept stable. (2) The periphery of the pressure-stabilizing air-conducting component is coated with sealant, so that the pressure-stabilizing air-conducting component is airtightly connected to the opening of the bottle body, which can prevent the milk in the bottle body from overflowing from the gap.

[0023] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Embodiment 1:

[0025] Reference Figure 1 , Figure 2As shown, a sucking bottle includes a pressure-stabilizing air guide 1, a nipple 2, a bottle body 3, and a screw cover 4. The nipple 2 is installed on the opening 31 of the bottle body 3 through the screw cover 4, and the screw cover 4 has an internal thread, and the outer periphery of the opening 31 of the bottle body 3 has an external thread, so that the screw cover 4 is threadedly connected to the bottle body 3, and the pressure-stabilizing air guide 1 is arranged between the bottle body 3 and the nipple 2.

[0026] Reference Figure 3 , Figure 4 As shown, specifically, the pressure-stabilizing air guide member 1 includes an outer ring 11 and an inner ring 12, and the outer ring 11 and the inner ring 12 are connected to form an air guide cavity 13, wherein a limiting flange is provided on the top surface of the outer ring 11, so that the pressure-stabilizing air guide member 1 is pressed against the opening 31 of the bottle body 3 through the limiting flange. In this embodiment, the surface where the outer ring 11 contacts the opening 31 of the bottle body 3 (i.e., the peripheral wall of the outer ring and the bottom surface of the limiting flange) is coated with a sealant 112. In this embodiment, the material used for the sealant 112 can be PET, silicone, etc., so that an airtight connection is formed between the opening 31 of the bottle body 3 and the sealant 112 of the pressure-stabilizing air guide member 1, thereby preventing the milk in the bottle body 3 from leaking out from the gap between the pressure-stabilizing air guide member 1 and the opening 31 when the baby sucks the milk, thereby effectively improving the sealing of the bottle.

[0027] In this embodiment, a needle withdrawal hole 113 is opened on the peripheral wall of the outer ring 11 corresponding to the air guide duct 15, so that the ejector pin can withdraw from the air guide duct 15 through the needle withdrawal hole 113 after the pressure-stabilizing air guide component 1 is injection-molded, and when the outer ring 11 is coated with the sealant 112, the sealant 112 is filled in the needle withdrawal hole 113 to ensure the sealing of the air guide cavity 13 and prevent air leakage.

[0028] Reference Figure 2 As shown, further, in this embodiment, the inner ring 12 is used to air-tightly cooperate with the lower opening of the nipple 2 to form a liquid guide channel 10 communicated with the bottle body 3, and the upper part of the outer wall of the inner ring 12 in this embodiment is an inclined surface, so that the inner ring 12 and the surface of the nipple 2 are more closely fitted, thereby improving the sealing between the inner ring 12 and the nipple 2, and by inverting the bottle body 3, the milk enters the nipple from the liquid guide channel 10 for the baby to suck the milk.

[0029] Combination Figure 2 , Figure 5As shown, in order to keep the pressure in the bottle body balanced with the outside world, in this embodiment, a connecting tube 14 is connected to the air guide cavity 13, and a plurality of air guide pipes 15 are arranged between the connecting tube 14 and the inner ring 12. In this embodiment, there are at least two air guide pipes 15, and they are arranged equidistantly around the circumference with the connecting tube 14 as the center, and the air guide pipes 15 are all connected to the connecting tube 14. The top surface of the outer ring 11 is provided with a plurality of grooves 111, and an air guide channel 17 communicating with the air guide cavity 13 is formed between the grooves 111 of the pressure-stabilizing air guide member 1 and the bottom surface of the nipple 2. The air guide cavity 13 and the air guide pipe 15 form a first air pressure balance channel through the grooves 111, which is conducive to the flow of air and makes the air guide cavity 13 connected with the outside world. An air guide pipe 16 is sleeved on the connecting tube 14, and the lower end of the air guide pipe 16 extends to the bottom surface of the bottle body 3, so that the baby can suck milk. In the embodiment, the outside air enters the first air pressure balance channel through the air guide channel 17, and is transported to the bottom of the bottle body 3 through the air guide pipe 15 and the air guide tube 16 in sequence, so that the air pressure in the bottle body 3 is stable, and the suction force during sucking can be greatly reduced through multiple air guide channels 17, so as to avoid too much negative pressure in the bottle, so that the baby can suck the milk more smoothly, and the milk spraying can be prevented from causing the baby to choke on the milk. When the baby sucks the milk upside down, the lower end of the air guide tube 16 is higher than the liquid level of the milk, and the air enters the bottle body 3 without contacting the milk, which greatly reduces the situation of bubbles in the milk. In addition, a one-way valve 161 is provided at the lower opening of the air guide tube 16. In this embodiment, the longitudinal section of the one-way valve 161 is V-shaped. The one-way valve 161 can be used to prevent the milk from entering the air guide tube 6, prevent the milk from remaining in the air guide tube 16, and prevent the air guide tube 16 from being uncleanly cleaned and breeding bacteria.

[0030] Embodiment 2:

[0031] Reference Figure 6 As shown, in this embodiment, the nipple 2 is provided with an air hole 21, and the lower end of the air hole 21 is provided with an air permeable one-way valve, so that the air hole 21 and the air guide cavity 13 form a second air pressure balance channel. When the baby sucks milk, the outside air enters the second air pressure balance channel through the air hole 21, and is sequentially transported to the bottom of the bottle body 3 through the air guide pipe 15 and the air guide tube 16, thereby achieving stable air pressure in the bottle body and ensuring that the baby can drink milk smoothly. The air permeable one-way valve in the air hole 21 and the one-way valve 161 in the air guide tube 16 can prevent milk from entering, making cleaning easier and not easy to breed bacteria.

[0032] In this embodiment, the nipple 2 with the air hole 21 and the pressure-stabilizing air guide 1 can be used together, or the pressure-stabilizing air guide 1 can be removed separately and only the bottle with the nipple 2 with the air hole can be used. The air-permeable one-way valve of the air hole 21 can prevent the milk in the bottle body 3 from overflowing from the air hole 21, and at the same time can ensure that the outside air is connected to the inside of the bottle body, so that the internal air pressure is stable.
