Description

Technical Field

[0001] This utility model relates to the field of infant and toddler products technology, and in particular to a newborn baby bottle. Background Technology

[0002] Traditional baby bottles have two main problems during use: first, infants may swallow too much air while drinking, leading to bloating; second, when the pressure inside the bottle is unbalanced, milk may spray out in a straight line, posing a choking risk. Current technology typically includes an air valve at the nipple, but this design cannot effectively prevent gas from entering the bottle through the milk and also cannot release vents. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a stable newborn baby bottle.

[0004] The present invention provides a newborn baby bottle, including a bottle body, wherein at least one pressure regulating hole is provided on the bottle body, and a switch for controlling the opening and closing of the pressure regulating hole is provided on the pressure regulating hole.

[0005] Furthermore, the pressure regulating hole is located on the side wall of the bottle, and when the bottle is in an inverted drinking position, the pressure regulating hole is above the milk surface.

[0006] Furthermore, the switch is a rotatable cover that selectively covers or exposes the pressure regulating hole by rotation.

[0007] Furthermore, the switch is a sliding slider that selectively covers or exposes the pressure regulating hole by sliding.

[0008] Furthermore, the pressure regulating hole is located in the area near the bottom 1 / 3 of the bottle body, and in a normal drinking posture, the pressure regulating hole is higher than the milk surface.

[0009] Furthermore, the inner side of the switch is provided with a sealing part corresponding to the pressure regulating hole. When the switch is moved to the closed position, the sealing part is pressed into the pressure regulating hole; when the switch is moved to the open position, the sealing part is completely disengaged from the airflow channel formed by the pressure regulating hole.

[0010] Furthermore, the diameter of the pressure regulating hole is 1-5 mm.

[0011] Furthermore, it also includes an extension conduit connected to the pressure regulating hole, the outlet of which is located in the bottom area of ​​the bottle body.

[0012] Furthermore, it also includes a nipple component, the bottom of which is provided with a snap-fit ​​element, and the bottle opening is provided with a rotatable snap-fit ​​ring; when the snap-fit ​​ring rotates upward, it engages with the snap-fit ​​element, locking the nipple component onto the bottle body; when the snap-fit ​​ring rotates downward, it disengages from the snap-fit ​​element, thereby disassembling the nipple component; the switch element is independently disposed within the snap-fit ​​ring, and the switch element moves independently of the snap-fit ​​ring.

[0013] Furthermore, a rotatable connection structure is provided between the nipple component and the bottle body, and the rotatable connection structure is located on the opposite side of the switch component; the rotatable connection structure includes a rotating shaft disposed on the nipple component and a shaft hole disposed on the bottle body, and the rotating shaft is rotatably mounted in the shaft hole; after the switch component opens the connection between the bottle body and the nipple component, the nipple component can rotate relative to the bottle body with the rotating shaft as the center.

[0014] The above technical solution has the following beneficial effects:

[0015] In this invention, when parents shake the bottle to prepare formula, a significant amount of gas is generated inside. The pressure regulating hole allows excess gas to escape, preventing the milk from spraying out in a straight line due to excessive internal pressure when the bottle is opened, which could cause the baby to choke. When the baby sucks on the bottle, the milk flows continuously, increasing the internal space and gradually reducing the pressure. When the bottle is inverted for drinking, outside air enters through the pressure regulating hole, preventing it from mixing with the milk and creating air bubbles that could cause bloating. Simultaneously, the milk flows smoothly under stable pressure, avoiding problems such as difficulty sucking or interrupted flow caused by low internal pressure. Attached Figure Description

[0021] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0022] It is readily understood that, based on the technical solution of this utility model, various structural and implementation methods can be interchanged by those skilled in the art without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meanings of the above-mentioned components within this utility model according to the specific circumstances.

[0025] In some embodiments of this utility model, a bottle body 1 is included, and at least one pressure regulating hole 11 is provided on the bottle body 1. A switch 2 for controlling the opening and closing of the pressure regulating hole 11 is provided on the pressure regulating hole 11.

[0026] The pressure regulating port 11 differs significantly from the air inlet valve on traditional nipples in terms of bottle pressure regulation, primarily in its bidirectional function and gas exchange method. 1. Bidirectional Function Difference: The pressure regulating port 11 can both allow air in and out. When the baby sucks on the bottle, the internal pressure decreases, allowing outside air to enter through the pressure regulating port 11, balancing the pressure and ensuring smooth milk flow. When the internal pressure rises due to changes in milk temperature, shaking, or other factors, excess gas can be expelled through the pressure regulating port 11. Traditional nipple air inlets are only one-way valves, typically allowing only outside air to enter the bottle and unable to expel excess gas. When the internal pressure rises for various reasons, excess gas cannot escape, potentially leading to unstable pressure and increasing the risk of milk spraying out. 2. Gas Exchange Method Difference: The air inlet and outlet processes of the pressure regulating port 11 are relatively direct, allowing gas exchange naturally based on the pressure difference between the inside and outside of the bottle. When the bottle is inverted for drinking, outside air enters directly into the upper space inside the bottle through the pressure regulating port 11, participating in pressure balance regulation. If the pressure inside the bottle is too high, gas is also directly expelled through the pressure regulating port 11. With traditional nipples, air entering the bottle must pass through the nipple and milk, causing air bubbles to form in the milk. When the pressure inside the bottle is unbalanced, the air intake valve's venting restriction prevents gas from being expelled in time.

[0027] Specifically, the bottle body 1 is the main container with a height of 120-180mm. The pressure regulating hole 11 is located on the side wall of the bottle body 1 at a distance of 50-80mm from the bottom. The switch 2 covers the outside of the pressure regulating hole 11 and has a diameter 3-5mm larger than the pressure regulating hole 11. The switch 2 is hinged to the bottle body 1 through a rotating shaft. The silicone sealing ring embedded in the switch 2 is interference-fitted with the edge of the pressure regulating hole 11.

[0028] In some embodiments of this utility model, the pressure regulating hole 11 is located 15-20mm above the bottom of the bottle body 1. When the bottle is inverted at 45°, the center point of the pressure regulating hole 11 is located 5-8mm above the liquid surface and forms an angle of 135° with the vertical direction (ensuring that it is always in the gas zone).

[0029] Among them, the change in liquid pressure distribution when inverted:

[0030] This solution addresses the pressure requirements of traditional baby bottles in different regions.

[0031] The pressure at the nipple is 1.2 kPa and 0.8 kPa.

[0032] Pressure regulating port 11: 0 kPa (0-0.2 kPa)

[0033] When the bottle is inverted for drinking, the gas exchange path is: outside air → pressure regulating port 11 (high position) → air bladder area on the top of the bottle → nipple, allowing gas to bypass the milk flow path. When sucking creates negative pressure,

[0034] When the pressure at the nipple drops, the pressure at the pressure regulating hole 11 is adjusted by the switch 2.

[0035] In some embodiments of this utility model, the pressure regulating hole 11 is located on the side wall of the bottle body 1. When the bottle is in an inverted drinking state, the pressure regulating hole 11 is located above the milk liquid surface.

[0036] Specifically, in this newborn baby bottle, the pressure regulating hole 11 is located on the side wall of the bottle body 1. This position is designed based on functional considerations when the bottle is inverted for drinking. When the bottle is in the inverted drinking position, the pressure regulating hole 11 must be above the milk surface. This positional relationship ensures that the pressure regulating hole 11 can effectively regulate air pressure during bottle use, preventing milk from clogging the pressure regulating hole 11 and ensuring smooth gas flow. There is a control connection between the pressure regulating hole 11 and the switch 2. The switch 2 is installed on the pressure regulating hole 11 and controls the opening and closing of the pressure regulating hole 11 through a specific structural design (such as a press-type or rotary type). The connection between the switch 2 and the pressure regulating hole 11 must be tight to prevent milk leakage during bottle use, while also ensuring that the switch 2 can be operated flexibly, allowing the user to easily open or close the pressure regulating hole 11 according to actual needs.

[0037] Working Principle: When the bottle is inverted for drinking, the baby sucks on the nipple, and the milk flows towards the nipple due to sucking, increasing the space inside the bottle and decreasing the air pressure. At this time, if the pressure regulating port 11 is open, outside air enters the bottle through the port, balancing the air pressure inside and outside the bottle, allowing the milk to flow smoothly and ensuring the baby can drink continuously and stably. When pressure adjustment is not needed, the pressure regulating port 11 is closed by operating the switch 2. Because the pressure regulating port 11 is sealed by the switch 2, milk cannot flow out from the port, thus achieving a leak-proof effect when shaking the bottle. Technical Effect: The pressure regulating port 11 replenishes air in a timely manner, preventing milk from flowing out due to low air pressure inside the bottle. This effectively solves problems such as difficulty in sucking and interrupted flow that may occur with traditional bottles, improving the baby's drinking experience. The stable air pressure environment ensures a uniform milk flow rate, preventing sudden increases in milk flow due to pressure changes, thereby reducing the risk of choking and ensuring the baby's drinking safety. The switch 2 enables users to control the opening and closing of the pressure regulating hole 11, allowing for flexible adjustment of the internal air pressure according to actual usage scenarios and needs, thus enhancing the adaptability and convenience of using the baby bottle.

[0038] In some embodiments of this utility model, the switch 2 is a rotatable cover that selectively covers or exposes the pressure regulating hole 11 by rotation.

[0039] Specifically, in the structure of the newborn baby bottle, the pressure regulating hole 11 is located on the side wall of the bottle body 1. When the bottle is in an inverted drinking position, the pressure regulating hole 11 is above the milk surface, ensuring its normal pressure regulation function. The switch 2 is a rotatable cap, tightly installed on the pressure regulating hole 11. The two are spatially corresponding vertically, and the size of the cap is adapted to the pressure regulating hole 11, which can completely cover or expose the pressure regulating hole 11 to control its opening and closing state. The rotatable cap and the pressure regulating hole 11 are connected by threads or snap-fit ​​connections to achieve a stable and rotatable assembly relationship. Taking a threaded connection as an example, the inner side of the cover has an internal thread that matches the outer thread of the pressure regulating hole 11. By rotating the cover, it can be screwed in or out along the thread of the pressure regulating hole 11, thereby covering or exposing the pressure regulating hole 11. If a snap-fit ​​connection is used, the cover will have protrusions and grooves that can engage or disengage with the snap-fit ​​structure around the pressure regulating hole 11. When the cover is rotated, the snap-fit ​​structure interacts, changing the relative position of the cover and the pressure regulating hole 11, thus achieving the purpose of opening and closing the pressure regulating hole 11. This connection method ensures that the cover will not easily fall off during use, while also allowing the cover to rotate flexibly, making it convenient for users to operate.

[0040] The working principle is as follows: When the pressure regulating hole 11 needs to be opened, the user rotates the cap in a specific direction to align the opening on the cap with the pressure regulating hole 11. At this time, the pressure regulating hole 11 is exposed, allowing outside air to enter the bottle. When the baby sucks on the bottle, this balances the air pressure inside the bottle with the outside air, ensuring smooth milk flow. When pressure adjustment is not needed, such as during shaking or temporary storage of the bottle, the user rotates the cap in the opposite direction to completely cover the pressure regulating hole 11, blocking the gas exchange channel between the bottle and the outside air, creating a sealed space, preventing milk from leaking out of the pressure regulating hole 11, and preventing outside air from entering the bottle. This simple operation of rotating the cap allows for quick and accurate control of the opening and closing of the pressure regulating hole 11, meeting the needs of different usage scenarios.

[0041] In some embodiments of this utility model, the switch 2 is a sliding slider that selectively covers or exposes the pressure regulating hole 11 by sliding.

[0042] Specifically, the pressure regulating hole 11 is still located on the side wall of the bottle body 1, above the milk surface when the bottle is inverted for drinking, ensuring that the pressure regulation function is not interfered with by the milk. A sliding slider is installed on the side wall surface of the bottle body 1 where the pressure regulating hole 11 is located, on the same plane as the pressure regulating hole 11. The size of the slider is adapted to the pressure regulating hole 11, completely covering it, and the sliding track of the slider is set around the pressure regulating hole 11, ensuring that the slider can effectively control the pressure regulating hole 11 at all times during the sliding process. The slider and the bottle body 1 are connected by a sliding groove structure. The side wall of the bottle body 1 has a sliding groove that matches the shape of the slider. The length direction of the sliding groove is consistent with the sliding direction of the slider. The slider is embedded in the sliding groove and can slide freely within it. The two side walls of the sliding groove limit the slider, preventing it from falling off the track during the sliding process, while ensuring that the slider can accurately cover or expose the pressure regulating hole 11 when sliding. In addition, to ensure that the slider can maintain its current position stably after it stops sliding, a slot or magnetic structure can be provided in the groove to cooperate with the corresponding protrusion or magnetic component on the slider, so that the slider will not move due to slight shaking of external force after covering or exposing the pressure regulating hole 11.

[0043] Working principle: When the pressure regulating hole 11 needs to be opened, the user pushes the slider along the groove, moving it from the position covering the pressure regulating hole 11 to one side, fully exposing it. At this time, outside air can enter the bottle through the pressure regulating hole 11, balancing the air pressure inside the bottle when the baby sucks, ensuring smooth milk flow. When pressure adjustment is not needed, such as during shaking or storing the bottle, the user pushes the slider in the opposite direction, causing it to cover the pressure regulating hole 11 again, blocking the gas exchange channel between the bottle and the outside, forming a closed space, preventing milk from leaking out of the pressure regulating hole 11, and preventing outside air from entering the bottle. Through a simple linear sliding operation, the user can quickly open and close the pressure regulating hole 11 to adapt to different usage scenarios.

[0044] In some embodiments of this utility model, the pressure regulating hole 11 is located in the area of ​​the bottom 1 / 3 of the bottle body 1, and in a normal drinking posture, the pressure regulating hole 11 is higher than the milk liquid surface.

[0045] Specifically, when a newborn drinks milk from an inverted bottle at approximately a 45-degree angle, the advantage of placing the pressure regulating hole 11 on the side wall of the bottle body 1 above the milk surface becomes apparent. This position ensures that the pressure regulating hole 11 is always exposed to air and will not be submerged by milk. Taking the pressure regulating hole 11 located near the bottom 1 / 3 of the bottle body 1 as an example, at this angle, even if the amount of milk in the bottle changes, the pressure regulating hole 11 is not easily covered by milk, maintaining continuous communication with the outside air and creating conditions for air pressure regulation. In this drinking posture, when the baby sucks on the nipple, the milk in the bottle flows towards the nipple, increasing the space inside the bottle and creating negative pressure. Because the pressure regulating hole 11 is above the milk surface, outside air can smoothly enter the bottle through the pressure regulating hole 11, balancing the air pressure inside the bottle and allowing the milk to flow out continuously and stably. At the same time, the 45-degree inverted posture combined with the position of the pressure regulating hole 11 makes the air entry path relatively stable, avoiding air directly impacting the milk and forming a large number of bubbles, reducing the risk of the baby inhaling bubbles and causing bloating and spitting up.

[0046] In some embodiments of this utility model, the inner side of the switch 2 is provided with a sealing part corresponding to the pressure regulating hole 11. When the switch 2 is moved to the closed position, the sealing part is pressed into the pressure regulating hole 11; when the switch 2 is moved to the open position, the sealing part is completely disengaged from the airflow channel formed by the pressure regulating hole 11.

[0047] Specifically, the sealing part is located inside the switch element 2, corresponding to the pressure regulating hole 11 on the bottle body 1. When the switch element 2 is installed at the pressure regulating hole 11 on the bottle body 1, the sealing part is precisely aligned with the pressure regulating hole 11. This positioning design allows the sealing part to accurately seal or open the pressure regulating hole 11. The sealing part and the switch element 2 are integrally molded, ensuring the stability of their connection. The switch element 2 is installed on the bottle body 1 in different ways (such as a threaded connection of a rotatable cap or a sliding groove connection of a sliding slider), thereby causing the sealing part to move with the movement of the switch element 2. When the switch element 2 moves, the sealing part can accurately enter and exit the pressure regulating hole 11, realizing the control of the opening and closing state of the pressure regulating hole 11. When it is necessary to close the pressure regulating hole 11, the user operates the switch element 2 to move to the closed position. As the switch element 2 moves, its inner sealing part is gradually pressed into the pressure regulating hole 11. Because the size of the sealing part is adapted to the pressure regulating hole 11, and it may use an elastic sealing material (such as silicone), when the sealing part is fully pressed into the pressure regulating hole 11, it can tightly fit the inner wall of the pressure regulating hole 11, forming an effective seal. This prevents outside air from entering the bottle and also prevents the milk from leaking out of the bottle through the pressure regulating hole 11. When it is necessary to open the pressure regulating hole 11, the user operates the switch 2 to move it to the open position. The switch 2 causes the sealing part to gradually disengage from the pressure regulating hole 11. After the sealing part is completely disengaged from the airflow channel formed by the pressure regulating hole 11, the pressure regulating hole 11 returns to unobstructed flow, and outside air can enter the bottle through the pressure regulating hole 11, balancing the air pressure inside the bottle and allowing the milk to flow out smoothly.

[0048] In some embodiments of this invention, the diameter of the pressure regulating hole 11 is 1-5 mm. Specifically, a pressure regulating hole 11 diameter of 1-5 mm ensures that the air inflow matches the changes in the internal space of the bottle, thus stably regulating the air pressure inside the bottle. During continuous sucking by the infant, it can replenish an appropriate amount of air in a timely manner, maintaining a stable milk flow and preventing situations where insufficient air pressure leads to difficulty in sucking or interruption of the flow, thereby improving the infant's drinking experience. The suitable hole diameter prevents air from rapidly entering the bottle and impacting the milk, effectively reducing the formation of air bubbles in the milk. Reducing air bubbles lowers the risk of the infant inhaling too much air, causing bloating, spitting up, and other problems, thus protecting the infant's gastrointestinal health.

[0049] In some embodiments of this invention, an extension conduit connected to the pressure regulating port 11 is also included, with the air outlet of the extension conduit located in the bottom area of ​​the bottle body 1. The extension conduit is connected to the pressure regulating port 11, with one end connected to the pressure regulating port 11 and the air outlet of the other end located in the bottom area of ​​the bottle body 1. When the bottle is being used for feeding, it will be inverted and at approximately a 45-degree angle to the vertical. At this time, the bottom area is a position far from the surface of the milk. This position ensures that the air outlet is not easily submerged in the milk, thus preventing air from entering the milk and providing a stable channel for air to enter and exit.

[0050] In some embodiments of this utility model, a nipple component 3 is also included. The bottom of the nipple component 3 is provided with a snap-fit ​​component 31, and the mouth of the bottle body 1 is provided with a rotatable snap-fit ​​ring 12. When the snap-fit ​​ring 12 rotates upward, it engages with the snap-fit ​​component 31 to lock the nipple component 3 onto the bottle body 1. When the snap-fit ​​ring 12 rotates downward, it disengages from the snap-fit ​​component 31 to disassemble the nipple component 3. The switch component 2 is independently disposed inside the snap-fit ​​ring 12, and the switch component 2 moves relatively independently from the snap-fit ​​ring 12.

[0051] Specifically, the nipple component 3 is located at the top of the bottle and is the part for the baby to suckle milk, directly contacting the baby's mouth. A connector is located at the bottom of the nipple component 3 and is used to connect with the snap-fit ​​ring 12. The snap-fit ​​ring 12 is installed at the mouth of the bottle body 1 and can rotate around the mouth of the bottle body 1. It is located at the connection point between the bottle body 1 and the nipple component 3, serving to connect and secure the two. The switch component 2 is independently located within the snap-fit ​​ring 12, in the same position area as the snap-fit ​​ring 12, but can move relatively independently, facilitating separate control of the installation and removal of the nipple component 3 and the opening and closing of the pressure regulating hole 11. The snap-fit ​​component 31 and the nipple component 3 are integrally molded and firmly connected to the bottom of the nipple component 3, ensuring that they will not separate during connection and removal. The snap-fit ​​ring 12 is installed at the mouth of the bottle body 1 via a rotating structure and can rotate circumferentially around the mouth of the bottle body 1, but will not detach from the mouth of the bottle body 1. This connection method ensures that the snap-fit ​​ring 12 can be stably installed on the bottle body 1 and can be rotated flexibly. When the snap-fit ​​ring 12 rotates upward, its locking structure engages with the snap-fit ​​piece 31, forming a tight connection and firmly locking the nipple piece 3 onto the bottle body 1; when the snap-fit ​​ring 12 rotates downward, the locking structure disengages from the snap-fit ​​piece 31, allowing the nipple piece 3 to be disassembled. The switch piece 2 is independently located within the snap-fit ​​ring 12, and although there is no direct mechanical linkage between the two, they are spatially interconnected. The switch piece 2 can move independently of the snap-fit ​​ring 12, such as rotating the cap or sliding the slider, to control the opening and closing of the pressure regulating hole 11. This structural design makes the layout of the various components of the bottle reasonable and makes full use of space. While ensuring functionality, it also makes the bottle's appearance more concise and beautiful, meeting the user's usage needs and aesthetic requirements.

[0052] A rotating connection structure 4 is provided between the nipple component 3 and the bottle body 1. The rotating connection structure 4 is located on the opposite side of the switch component 2. The rotating connection structure 4 includes a rotating shaft on the nipple component 3 and a shaft hole on the bottle body 1. The rotating shaft is rotatably installed in the shaft hole. After the switch component 2 opens the connection between the bottle body 1 and the nipple component 3, the nipple component 3 can rotate relative to the bottle body 1 with the rotating shaft as the center.

[0053] In some embodiments of this utility model, specifically, the rotating connection structure 4 is located between the nipple component 3 and the bottle body 1, and is positioned directly opposite the location of the switch component 2. This positional distribution ensures that the nipple component 3 experiences uniform force when rotated open, guaranteeing the stability and smoothness of rotation. The rotating shaft is located on the nipple component 3, typically at the bottom edge of the nipple component 3, and is integrally formed with the nipple component 3 or fixed by a secure assembly method. The shaft hole is opened on the bottle body 1, corresponding to the position of the rotating shaft on the nipple component 3, and is located in the edge area of ​​the bottle body 1 opening, ensuring accurate assembly of the rotating shaft. The nipple component 3 is fixedly connected to the bottle body 1 through the engagement of the snap-fit ​​component 31 and the snap-fit ​​ring 12. Simultaneously, a rotatable connection is established on the opposite side of the location of the switch component 2 through the rotating connection structure 4 between the rotating shaft and the shaft hole. These two connection methods work together to ensure that the nipple component 3 can be securely installed on the bottle body 1 and can be rotated open under specific operations. During normal use, the snap-fit ​​ring 12 rotates upwards to engage with the snap-fit ​​piece 31 at the bottom of the nipple component 3, firmly locking the nipple component 3 onto the bottle body 1. Simultaneously, the switch 2 can control the opening and closing of the pressure regulating hole 11 as needed. When it is necessary to open the nipple component 3, rotate the snap-fit ​​ring 12 downwards to disengage it from the snap-fit ​​piece 31. At this point, the nipple component 3 is only connected to the bottle body 1 via the rotating connection structure 4. Finally, with the rotation axis as the center, the nipple component 3 rotates relative to the bottle body 1 to open, facilitating parents to observe the milk level in the bottle, perform cleaning operations, or add milk. To close, rotate the nipple component 3 back to its original position, first rotating the snap-fit ​​ring 12 upwards to engage the snap-fit ​​piece 31.

[0054] In this invention, when parents shake the bottle to prepare formula, a significant amount of gas is generated inside. The pressure regulating hole 11 allows excess gas to escape, preventing the milk from spraying out in a straight line due to excessive internal pressure when the bottle is opened, which could cause the baby to choke. When the baby sucks on the bottle, the milk flows continuously, increasing the internal space and gradually reducing the air pressure. When the bottle is inverted for drinking, outside air enters through the pressure regulating hole 11, preventing it from mixing with the milk and creating air bubbles that could cause bloating. Simultaneously, the milk flows smoothly under stable pressure, avoiding problems such as difficulty sucking or interrupted flow caused by low internal pressure.

[0055] The above are merely the principles and preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of this utility model, and these modifications should also be considered within the scope of protection of this utility model.
