Description

Technical Field

[0001] This utility model relates to the field of drinking cup technology, specifically to a venting and anti-spraying scientific drinking cup. Background Technology

[0002] A sippy cup is an indispensable tool for newborn feeding. Traditional sippy cups typically use a simple straw or nipple structure, lacking a design to prevent liquids such as water from spraying out. When a baby sucks vigorously or the cup is tilted at an excessive angle, liquid can easily spray out due to pressure differences, resulting in wasted liquid, discomfort for the infant during feeding, or even choking, posing a safety risk. Furthermore, spraying liquid can stain clothes and the surrounding environment, adding an extra cleaning burden for parents. Utility Model Content

[0003] This utility model provides a venting and anti-spray drinking cup to solve the problem of liquid easily spraying out of the drinking cup in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a venting and anti-spray sippy cup, comprising a hollow bottle body with one end open, a hollow fixed cap detachably provided at one end of the bottle body opening, a top cap detachably provided at the end of the fixed cap away from the bottle body, an elastic ventilation membrane provided inside the fixed cap, the ventilation membrane being used to allow gas to circulate between the cavity formed by the ventilation membrane and the bottle body and the cavity formed by the ventilation membrane and the top cap, and the ventilation membrane being able to prevent liquid flow, a ventilation channel being formed on the top cap and / or at the connection between the fixed cap and the ventilation membrane, a hollow straw connector being provided at the center of the ventilation membrane, an upper straw being provided between the straw connector and the top cap, and a lower straw being provided at the bottom of the straw connector;

[0005] The straw connector is equipped with an elastic anti-spray diaphragm. A piston is located at the bottom center of the anti-spray diaphragm. At least one third opening is formed in the area of ​​the anti-spray diaphragm that does not coincide with the position of the piston. The piston can slide inside the lower straw. When the pressure inside the upper straw is less than the pressure inside the lower straw and the pressure difference reaches a set value, the piston moves away from the lower straw. When the pressure inside the upper straw is greater than or equal to the pressure inside the lower straw, the piston is located inside the lower straw, blocking the lower straw.

[0006] Furthermore, the ventilation diaphragm surrounds the straw connector in an annular wave structure, and the ventilation diaphragm has at least one peak protruding towards the top cover and at least one trough protruding towards the bottom. At least one first opening is formed at the bottom of each trough, and at least one second opening is provided at the top of each peak.

[0007] Furthermore, a first fastener is formed at the bottom of the straw connector, and a second fastener is formed at the top of the lower straw. When the first fastener and the second fastener are engaged, the straw connector is fixedly connected to the lower straw.

[0008] Furthermore, the straw is made of flexible material, and a gravity ball is installed at the bottom of the straw.

[0009] Furthermore, anti-slip textures are formed on the bottle.

[0010] Furthermore, the inner diameter of the upper straw is larger than the outer diameter of the straw connector.

[0011] Furthermore, a sealing ring is provided at the connection between the upper straw and the straw connector.

[0012] Furthermore, a nipple is provided at the top of the upper straw.

[0013] Furthermore, the top of the cover is foldable and has a flip cover.

[0024] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0025] like Figure 1-5 As shown, this utility model embodiment provides a venting and anti-spray sippy cup, including a hollow bottle body 1 with one end open. A hollow fixed cap 2 is detachably provided at the open end of the bottle body 1. A top cap 3 is detachably provided at the end of the fixed cap 2 away from the bottle body 1. An elastic ventilation membrane 4 is provided inside the fixed cap 2. The ventilation membrane 4 is used to allow gas to flow between the cavity formed by the ventilation membrane 4 and the bottle body 1 and the cavity formed by the ventilation membrane 4 and the top cap 3. The ventilation membrane 4 can also prevent liquid flow. A ventilation channel 7 is formed on the top cap 3 and / or at the connection between the fixed cap 2 and the ventilation membrane 4. A hollow straw connector 9 is provided at the center of the ventilation membrane 4. An upper straw 5 is provided between the straw connector 9 and the top cap 3. A lower straw 6 is provided at the bottom of the straw connector 9 (in a specific embodiment, the lower straw 6 and the straw connector 9 are integrally formed).

[0026] In one embodiment, the ventilation membrane 4 surrounds the straw connector 9 in an annular wave structure, that is, the ventilation membrane 4 has a wave crest 41 protruding towards the top cover 3 and a wave trough 42 protruding towards the bottom of the bottle body 1. There is at least one wave crest 41 and a wave trough 42. At least one first opening 43 is formed at the bottom of each wave trough 42, and at least one second opening 44 is provided at the top of each wave crest 41. (In one specific embodiment, the ventilation membrane 4 is made of silicone. Silicone has excellent high temperature resistance and corrosion resistance, so that the ventilation membrane 4 will not be easily corroded and damaged in the drinking cup.) In another embodiment, the ventilation membrane 4 is made of hydrophobic filter membranes such as polytetrafluoroethylene filter membranes and polyvinylidene fluoride filter membranes. Hydrophobic filter membranes can prevent water and other liquids from adhering to or penetrating the ventilation membrane 4, while gas can pass freely through the ventilation membrane 4.

[0027] Under normal conditions, both the first opening 43 and the second opening 44 are closed, preventing the flow of gas and liquid between the cavity formed by the venting diaphragm 4 and the bottle body 1 and the cavity formed by the venting diaphragm 4 and the top cap 3. When liquid is drawn in, as the liquid level in the bottle body 1 decreases, the pressure in the cavity formed by the venting diaphragm 4 and the top cap 3 becomes greater than the pressure in the cavity formed by the venting diaphragm 4 and the bottle body 1. The venting diaphragm 4 deforms downwards under this pressure, causing the first opening 43 to open (located at the trough 42) and the second opening 44 to close (located at the crest 41). Gas then flows through the first opening 43. 3. Gas passes through the ventilation diaphragm 4 and enters the cavity formed by the ventilation diaphragm 4 and the bottle body 1. When high-temperature liquid is stored in the drinking cup, the gas in the cavity formed by the ventilation diaphragm 4 and the bottle body 1 expands due to heat, making the pressure in the cavity formed by the ventilation diaphragm 4 and the top cover 3 less than the pressure in the cavity formed by the ventilation diaphragm 4 and the bottle body 1. The ventilation diaphragm 4 is deformed upward under pressure, causing the first opening 43 to close tightly (set on the trough 42) and the second opening 44 to open (set on the crest 41). Gas passes through the second opening 44 and enters the cavity formed by the ventilation diaphragm 4 and the top cover 3.

[0028] A first fastener 91 is formed at the bottom of the straw connector 9, and a second fastener 61 is formed at the top of the lower straw 6. When the first fastener 91 and the second fastener 61 are engaged, the straw connector 9 is fixedly connected to the lower straw 6. An elastic anti-spray diaphragm 92 is provided inside the straw connector 9. A piston 93 is provided at the bottom center of the anti-spray diaphragm 92. At least one third opening 94 is formed in the area of ​​the anti-spray diaphragm 92 that does not coincide with the position of the piston 93. Under normal conditions, the pressure inside the lower straw 6 is equal to the pressure inside the upper straw 5. The piston 93 extends into the lower straw 6 and can slide inside the lower straw 6. When the pressure inside the upper straw 5 is less than the pressure inside the lower straw 6... When the pressure difference reaches the set value (the set value refers to the pressure difference that allows the piston 93 to move away from the lower suction tube 6), the piston 93 moves away from the lower suction tube 6, allowing the liquid to enter the upper suction tube 5 through the suction tube connector 9 from the lower suction tube 6. The piston 93 moves away from the lower suction tube 6, causing the anti-blowout diaphragm 92 to move upward, opening the third opening 94 on the anti-blowout diaphragm 92, allowing the liquid to pass through the third opening 94 and enter the upper suction tube 5. When the pressure in the upper suction tube 5 is greater than or equal to the pressure in the lower suction tube 6, the piston 93 is located in the lower suction tube 6, preventing the liquid from entering the upper suction tube 5 from the lower suction tube 6, thus blocking the lower suction tube 6.

[0029] Obviously, when there are multiple first openings 43, second openings 44 and third openings 94, the opening and closing actions of the first opening 43, second opening 44 and third opening 94 are small each time, which facilitates the exchange of gas inside and outside the bottle, prevents suffocation and high-pressure splashing, and the first opening 43, second opening 44 and third opening 94 are in a natural elastic opening and closing state, so that the ventilation diaphragm 4 and the anti-spray diaphragm 92 are not easily damaged due to material fatigue.

[0030] When a newborn lifts their hands to drink liquid, the cup tilts towards the newborn. Due to gravity, the liquid flows to the bottom of the cup closest to the newborn, preventing the bottom of the straw 6 from being submerged in the liquid. This prevents the newborn from drinking the liquid at the bottom. To prevent this, in a preferred embodiment of this invention, the straw 6 is made of flexible materials such as silicone or copolyester. A gravity ball 8 is provided at the bottom of the straw 6. When the newborn drinks liquid, the bottom of the straw 6 bends towards the liquid accumulation point under the influence of the gravity ball 8, so that the bottom of the straw 6 is submerged in the liquid.

[0031] To facilitate newborns in drinking milk, in a preferred embodiment of this invention, a nipple 51 (including breast-type, duckbill-type, etc.) is provided at the top of the upper straw 5.

[0032] To prevent dust from entering the upper straw 5, in a preferred embodiment of this invention, the top cover 3 is provided with a flip cover 31 that can be flipped. When the flip cover 31 covers the upper straw 5, the upper straw 5 is not connected to the outside air. When the flip cover 31 leaves the top of the upper straw 5, the newborn can drink milk from the cup through the upper straw 5. It is foreseeable that when the top of the upper straw 5 is provided with a nipple 51, when the flip cover 31 covers the nipple 51, the nipple 51 is not connected to the outside air. When the flip cover 31 leaves the top of the nipple 51, the newborn can drink milk from the cup through the nipple 51.

[0033] To prevent the drinking cup from slipping from a newborn's hands, in a preferred embodiment of this invention, the bottle body 1 is provided with anti-slip texture.

[0034] To prevent the drinking cup from slipping from a newborn's hand, in a preferred embodiment of this utility model, a handle 21 is provided on the bottle body 1 or the fixed cap 2.

[0035] To prevent liquid from leaking out from the connection between the straw connector 9 and the upper straw 5, in a preferred embodiment of this invention, the inner diameter of the upper straw 5 is larger than the outer diameter of the straw connector 9.

[0036] To further prevent liquid from leaking out from the connection between the straw connector 9 and the upper straw 5, in a preferred embodiment of this utility model, a sealing ring is provided at the connection between the upper straw 5 and the straw connector 9.

[0037] In summary, this anti-spray sippy cup, through the straw connector 9 and the ventilation diaphragm 4, prevents liquid from easily spraying out of the cup, thus avoiding the phenomenon of liquid spraying out of the top cover 3 due to excessive pressure inside the cup.

[0038] The embodiments described above merely illustrate the implementation of this utility model, and should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
