Description

Technical Field

[0001] This utility model relates to the technical field of baby bottles, specifically to a spiked defoaming filter and a baby bottle. Background Technology

[0002] A baby bottle is a container used to prepare formula, which is then mixed to form milk for the baby to drink. In the preparation process, the formula powder is first placed inside the bottle, and then warm water is poured in to dissolve it. To speed up the dissolution process, the bottle is usually shaken to increase the efficiency of the formula dissolving.

[0003] However, air will be present in the bottle. When formula is prepared and shaken, the milk mixes with air, causing some air to directly enter the milk and form bubbles. After shaking, bubbles will remain in the milk. If the baby drinks milk containing bubbles, the air in the baby's stomach will be difficult to expel, which can cause bloating, crying, hiccups, and in severe cases, spitting up, making it inconvenient for the baby to drink. Utility Model Content

[0004] This invention provides a spiked defoaming filter and a baby bottle to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides a spiky defoaming filter, comprising:

[0006] The separator has a separation hole to separate milk and air bubbles. One side of the separator has a defoaming part that protrudes and punctures the air bubbles when it comes into contact with them.

[0007] When filtering air bubbles in the milk, the separator located in the bottle punctures the air bubbles through the defoaming part and filters the milk to separate the air bubbles from the milk.

[0008] Preferably, the defoaming portion extends from one side of the separating member along the opening direction of the separating hole.

[0009] Preferably, the defoaming part has a large end and a puncture end, the large end is fixed to one side of the separating member, and its cross-sectional area gradually decreases in the direction away from the separating member, extending to form the puncture end.

[0010] Preferably, there are multiple defoaming sections, and the multiple defoaming sections are arranged at equal angles with the geometric center of the separating member as the center.

[0011] Preferably, the separation hole is an arc-shaped hole, and the center of the separation hole coincides with the geometric center of the separation component.

[0012] Preferably, the separating member has a separating part, which is disposed between two adjacent separating holes, and the defoaming part is disposed on the separating part.

[0013] Preferably, the defoaming section is conical.

[0014] Preferably, the defoaming part is pyramidal in shape.

[0015] A baby bottle, comprising:

[0016] As described in any of the above-mentioned spiky defoaming filters;

[0017] The bottle body has an internal liquid storage chamber, and the spiked defoaming filter is installed inside the liquid storage chamber.

[0018] Preferably, the bottle body has a milk outlet communicating with the liquid storage chamber. Along the axial direction of the milk outlet, the spiky defoaming filter partially blocks the milk outlet, and the spiky defoaming filter is located between the milk outlet and the liquid storage chamber, with the defoaming part of the spiky defoaming filter located inside the liquid storage chamber.

[0019] The spiked defoaming filter and baby bottle proposed in this utility model have the following beneficial effects:

[0020] The spiky defoaming filter and baby bottle proposed in this invention distribute a large number of bubbles (ranging from hundreds of micrometers to several millimeters in diameter) generated after brewing or shaking within the liquid storage chamber. During feeding, due to the pressure difference created by tilting and sucking, the milk carrying the bubbles flows towards the milk outlet and first passes through the separator.

[0021] The defoaming section protrudes from the surface of the separator into the cavity, extending into the liquid storage chamber. Some air bubbles will directly contact the defoaming section. When a bubble contacts the defoaming section, the bubble film is pinned at the tip. The curvature difference between the curved surface and the tip increases the local pressure difference. Combined with the flow shearing effect, the bubble film rapidly thins and ruptures. After rupture, the gas is directly released back into the void area of ​​the liquid storage chamber.

[0022] For air bubbles that have not yet been punctured or have not yet completely broken, they are separated by a separator. The separation hole allows milk to pass through while blocking air bubbles to prevent the outflowing milk from containing air bubbles.

[0023] The active defoaming action of the piercing contact of the defoaming section and the passive sieving action of the separation holes work together to ensure that the bubbles are first pierced by the contact and then filtered by the separation holes, thereby preventing infants from drinking milk containing bubbles and avoiding bloating, hiccups and other problems.

[0033] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0034] It should be noted that in the description of this utility model, the terms "lateral," "longitudinal," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] This utility model proposes a spiky defoaming filter 100, comprising:

[0036] The separator 110 has a separation hole 111 for separating milk and air bubbles. A defoaming part 112 protrudes from one side of the separator 110. When the defoaming part 112 comes into contact with the air bubbles, it punctures the air bubbles.

[0037] When filtering air bubbles in the milk, the separator 110 located in the bottle 200 punctures the air bubbles through the defoaming part 112 and filters the milk so that the air bubbles are separated from the milk.

[0038] In this embodiment, a large number of air bubbles (ranging in diameter from hundreds of micrometers to several millimeters) generated after brewing or shaking are distributed in the liquid storage chamber. During feeding, due to the pressure difference created by tilting and sucking, the milk carrying the air bubbles flows towards the milk outlet 220 and first passes through the separator 110.

[0039] The defoaming section 112 protrudes from the surface of the separator 110 into the cavity and extends into the liquid storage chamber. Some bubbles will directly contact the defoaming section 112. When a bubble contacts the defoaming section 112, the bubble film is pinned at the tip. The curvature difference between the curved surface and the tip increases the local pressure difference. Combined with the flow shearing effect, the bubble film rapidly thins and ruptures. After rupture, the gas is directly released back into the void area of ​​the liquid storage chamber.

[0040] For air bubbles that have not yet been punctured or have not yet completely broken, they are separated by the separator 110. The separator 111 allows milk to pass through while blocking air bubbles to prevent the outflowing milk from containing air bubbles.

[0041] The active defoaming of the defoaming section 112 and the passive sieving of the separation hole 111 work together to first puncture and then filter, thereby preventing infants from drinking milk containing bubbles and avoiding bloating, hiccups and other problems.

[0042] It should be noted that the separator 110 is a disc-shaped plastic part, the outer diameter of which matches the inner hole of the nipple holder, and it is equipped with circumferential buckles; the material is PPSU or Tritan. The separator hole 111 is a number of arc-shaped holes opened on the disc, and the center of each arc-shaped hole is consistent with the geometric center of the disc (concentric arcs).

[0043] The arc-shaped ribs between adjacent arc-shaped holes constitute the separation section 113. The defoaming section 112 has a conical spike integrally formed on one side (the side facing the liquid storage chamber) of each separation section 113. The large end 1121 of the spike is connected to the separation section 113 and extends along the opening direction of the separation hole 111, with the spike tip pointing towards the incoming liquid direction. Multiple conical spikes are arranged circumferentially at equal angles around the geometric center of the separation member 110, and one or more defoaming sections 112 are distributed on each separation section 113.

[0044] The separator 110 is installed between the milk outlet 220 and the liquid storage chamber, partially obstructing the milk outlet 220 when viewed axially, and the spiked end is located inside the liquid storage chamber.

[0045] When the milk containing bubbles flows towards the separator 110, the large bubbles are first punctured by the conical spikes. The small bubbles and liquid continue to enter the arc-shaped separation hole 111. With the help of gravity / buoyancy and the shearing of the hole edge, the gas and liquid are separated.

[0046] Preferably, the defoaming portion 112 extends from one side of the separating member 110 along the opening direction of the separating hole 111.

[0047] In this embodiment, since the defoaming part 112 and the separation hole 111 are arranged in the same direction, the milk will first come into contact with the defoaming part 112 when it passes through the separation hole 111. The bubble film will experience a sudden change in curvature and stress concentration at the tip of the defoaming part 112. Combined with the shear of the main stream, it will first break at the tip and the gas will be released into the upstream space and will no longer flow with the milk.

[0048] Even if there are unbroken bubbles, as they pass through the separation hole 111, the bubbles are blocked by the separator 110, allowing the milk to flow out through the separation hole 111 while the bubbles are blocked, thus forming gas-liquid separation.

[0049] Since the length direction of the defoaming part 112 is arranged along the opening direction of the separation hole 111, when the milk flows out through the separation hole 111 and forms a flow channel, the probability of contact between the air bubbles and the defoaming part 112 is increased, thereby increasing the probability of puncturing the air bubbles.

[0050] Preferably, the defoaming part 112 has a large end 1121 and a puncture end 1122. The large end 1121 is fixed to one side of the separating member 110, and its cross-sectional area gradually decreases in the direction away from the separating member 110, extending to form the puncture end 1122.

[0051] In this embodiment, a plurality of defoaming portions 112 are integrally formed on the side of the separator 110 facing the liquid. The end of each defoaming portion 112 near the separator 110 is a large end 1121, which is integrally fixed to the separator 110. From the large end 1121 to the direction away from the separator 110, the cross-section continuously decreases, and the end forms a sharp point as a piercing end 1122.

[0052] When bubble-laden milk flows from the side of the separator 110 near the defoaming section 112, it first encounters the defoaming section 112. The large end 1121 of the defoaming section 112 is integrally fixed with the separator 110, providing sufficient structural strength and bearing area. Along the direction away from the separator 110, the cross-sectional area of ​​the defoaming section 112 gradually decreases and eventually forms a puncture end 1122, causing the flowing bubbles to be guided to the tip and subjected to localized pressure. The radius of curvature of the bubble membrane decreases sharply, and the membrane tension threshold is exceeded, causing it to rupture at the puncture end 1122. The punctured gas no longer continues to flow out in the form of a complete large bubble, while the small bubbles undergo further gas-liquid separation near the separation hole 111, reducing the gas content entering the milk outlet 220 side.

[0053] The continuous gradual narrowing from the large end 1121 to the puncture end 1122 increases the probability of contact between the bubble and the defoaming part 112, thus improving the success rate of bubble breaking.

[0054] Preferably, there are multiple defoaming sections 112, and the multiple defoaming sections 112 are arranged at equal angles with the geometric center of the separator 110 as the center.

[0055] In this embodiment, several defoaming parts 112 are arranged on the liquid-facing side of the separator 110, and are distributed in a circumferential circumferential angle around the geometric center. Each defoaming part 112 is respectively disposed between two adjacent separation holes 111. The circumferential circumferential distribution ensures that bubbles can encounter the defoaming part 112 within a short path under different feeding postures and incoming flow directions, thereby improving the consistency of puncture.

[0056] Preferably, the separation hole 111 is an arc-shaped hole, and the center of the separation hole 111 coincides with the geometric center of the separation member 110.

[0057] In this embodiment, the separation hole 111 is an arc-shaped hole, and the center of the arc-shaped hole is the geometric center of the separation member 110. The circumferential arc-shaped hole allows the milk to pass through in an approximately tangential manner when passing through the arc-shaped hole, making the flow smoother, thereby reducing secondary foaming and avoiding the generation of swirling flow.

[0058] Preferably, the separating member 110 is provided with a separating part 113, the separating part 113 is disposed between two adjacent separating holes 111, and the defoaming part 112 is disposed on the separating part 113.

[0059] In this embodiment, on the side of each separation section 113 facing the liquid storage cavity, a plurality of defoaming sections 112 are arranged along the opening direction of the separation hole 111, so that the bubbles in the milk can come into contact with one of the defoaming sections 112 and be punctured.

[0060] When breastfeeding, as milk flows from the storage chamber to the outlet 220, the air bubbles carried by the flow will inevitably pass through the bubble-breaking zone along the direction of the separation hole 111, thereby contacting and being punctured by one of the defoaming parts 112, and then completing gas-liquid separation through the separation holes 111 on both sides.

[0061] Multiple defoaming sections 112 are arranged continuously in the opening direction of the separation hole 111. When the bubbles pass by the separation section 113 with the mainstream, they can always come into contact with one of the defoaming sections 112 and be punctured, which significantly improves the success rate of bubble breaking.

[0062] Preferably, the defoaming part 112 is conical.

[0063] In this embodiment, the defoaming part 112 has an axisymmetric conical shape, with a larger circular cross section at the end near the separator 110 and a gradually converging point at the end away from the separator 110, which is used to contact and puncture the bubbles.

[0064] On the separation section 113 of the separator 110 (located between two adjacent separation holes 111), on the side facing the liquid storage cavity, a plurality of conical defoaming sections 112 are arranged along the opening direction of the separation holes 111. The conical bottom surface of each conical defoaming section 112 is integrally connected to the separation section 113, and the conical tip faces the liquid storage cavity. Three or more conical defoaming sections 112 can be equidistantly arranged on the same separation section 113, so that the flowing bubbles will inevitably come into contact with at least one of them and be punctured.

[0065] The cone shape continuously converges outward from the side of the separator 110. The bubble is guided to the tip of the cone by the flow field, and the local contact stress is concentrated, making it easy to puncture at the tip of the cone.

[0066] Preferably, the defoaming part 112 is pyramidal in shape.

[0067] In this embodiment, a separation portion 113 is formed between two adjacent separation holes 111 on the separation member 110. On the side facing the liquid storage cavity, multiple pyramidal defoaming portions 112 (such as triangular pyramids, quadrangular pyramids or hexagonal pyramids) are arranged along the opening direction of the separation holes 111. The bottom surface is integrally connected to the separation portion 113, and the tip faces the liquid storage cavity.

[0068] When the bubble-containing milk passes through the separation section 113 along the opening direction of the separation hole 111, some of the bubbles come into contact with one of the defoaming sections 112 and are punctured at the puncture end 1122, while the other part of the bubbles completes gas-liquid separation through the separation holes 111 on both sides.

[0069] The edges of the pyramid create higher local contact stress and shear on the upstream side, making it easier for adhering or slipping bubbles to rupture at the puncture end 1122.

[0070] No matter which direction the incoming flow comes from, there is always an edge that is in the direction of the flow, ensuring a stable bubble-breaking effect.

[0071] A type of baby bottle 200 includes:

[0072] The spiky defoaming filter 100 as described in any of the above items;

[0073] The bottle body 210 has a liquid storage chamber inside, and the spiked defoaming filter 100 is installed in the liquid storage chamber.

[0074] In this embodiment, during use, milk containing bubbles flows through the pierced defoaming filter 100 in the storage chamber. First, some bubbles come into contact with the defoaming part 112 protruding on one side of the separator 110 and are pierced. The other part of the bubbles that do not come into contact with the defoaming part 112 are separated from the milk when passing through the separation hole 111, thereby making the outflowing milk less bubble-filled and avoiding the baby from inhaling bubbles, which could cause hiccups, bloating, etc.

[0075] Preferably, the bottle body 210 has a milk outlet 220 communicating with the liquid storage chamber. Along the axial direction of the milk outlet 220, the spiked defoaming filter 100 partially blocks the milk outlet 220, and the spiked defoaming filter 100 is located between the milk outlet 220 and the liquid storage chamber. The defoaming part 112 of the spiked defoaming filter 100 is located inside the liquid storage chamber.

[0076] In this embodiment, the spiked defoaming filter 100 is arranged along the axial direction of the milk outlet 220 and partially blocks the milk outlet 220, so that the path from the liquid storage chamber to the milk outlet 220 must pass through the spiked defoaming filter 100. Before reaching the milk outlet 220, the milk containing bubbles must first come into contact with the defoaming part 112 on the side of the liquid storage chamber. Larger bubbles are preferentially punctured, and the other part of the bubbles that do not come into contact with the defoaming part 112 are then separated from the milk when passing through the separation hole 111.

[0077] This results in fewer air bubbles in the milk and a more continuous flow, thereby reducing the amount of air the baby takes in during sucking and lowering the probability of discomfort such as hiccups and bloating.

[0078] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
