Description

Technical Field

[0001] The present invention relates to the technical field of baby bottles, and particularly relates to a flow control straw and a baby bottle. Background Art

[0002] There are various baby bottles on the market. A straw is used to connect the nipple to the baby bottle to facilitate infants' self-feeding. Micro water outlet holes are provided on the nipple. When the baby bites or sucks the nipple, the micro water outlet holes located inside the nipple are squeezed, and the micro water outlet holes open. The liquid in the bottle can be sucked out through the micro water outlet holes. The micro water outlet holes are formed by cutting or punching processes, so that the micro water outlet holes have a fixed water output when the baby sucks the liquid in the bottle. However, after the baby bites the nipple multiple times, the micro water outlet holes may be permanently deformed and ruptured, resulting in an increased water output when using the baby bottle and choking the baby. It is necessary to replace the nipple or even the entire baby bottle. In addition, when the baby grows up, a larger water output is required from the nipple to meet the baby's drinking needs.

[0042] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0043] According to some embodiments of the present invention, referring to Figures 1 to 4, A flow control straw is applied to a baby bottle. The flow control straw is located inside the baby bottle. The flow control straw includes a connecting pipe 100, a water inlet head 200, and a flow control structure 210. The upper end of the connecting pipe 100 is provided with a water outlet part 110, and the water outlet part 110 is used for detachably connecting with the nipple 310 of the baby bottle; the lower end of the connecting pipe 100 is connected to the water inlet head 200, and the flow control structure 210 is arranged in the water inlet head 200 or the connecting pipe 100.

[0044] When the flow control structure 210 is arranged in the water inlet head 200, liquid can enter the inner cavity of the water inlet head 200 through the flow control structure 210. Since the water inlet head 200 is connected to the connecting pipe 100, the liquid can enter the inner cavity of the connecting pipe 100 through the water inlet head 200, and finally the liquid is discharged through the water outlet part 110. The flow control structure 210 can control the water inflow volume of the liquid entering the connecting pipe 100 through the water inlet head 200.

[0045] When the flow control structure 210 is arranged in the connecting pipe 100, the liquid entering the connecting pipe 100 can pass through the flow control structure 210 and be discharged through the connecting pipe 100. The flow control structure 210 can control the water flow volume of the liquid passing through the connecting pipe 100.

[0046] Preferably, when the flow control structure 210 is arranged in the water inlet head 200, the material of the water inlet head 200 is silicone. The flow control structure 210 includes a plurality of elastic valve flaps formed by cutting the water inlet head 200 through a cutting process. The plurality of elastic valve flaps press against each other to form a slit. Refer to Figure 4 , when the flow control straw is installed in the baby bottle, the upper end of the connecting pipe 100 is connected to the nipple 310, and the lower end of the connecting pipe 100 is connected to the water inlet head 200. When sucking liquid through the nipple, the gas in the connecting pipe 100 will be sucked away, making the pressure in the bottle body 300 greater than the pressure in the connecting pipe 100. The elastic valve flaps bend towards the water outlet direction, causing the slit to be opened, so that the liquid can enter the connecting pipe 100 through the water inlet head 200.

[0047] Preferably, when the flow control structure 210 is arranged in the connecting pipe 100, the flow control structure 210 includes a plurality of elastic valve flaps. The plurality of elastic valve flaps press against each other to form a slit. When the flow control straw is installed in the baby bottle, the upper end of the connecting pipe 100 is connected to the nipple 310, and the lower end of the connecting pipe 100 is connected to the water inlet head 200. When sucking liquid through the nipple, the gas above the flow control structure 210 in the connecting pipe 100 will be sucked away, resulting in the air pressure below the flow control structure 210 in the connecting pipe 100 being greater than the air pressure above the flow control structure 210 in the connecting pipe 100. The elastic valve flaps bend towards the water outlet direction, and the slit is opened, so that the liquid can pass through the flow control structure 210 and be discharged from the connecting pipe 100.

[0048] It can be understood that the shape of the slit can be in the shape of a "one", that is, the flow control structure 210 includes two elastic valve flaps, and the slit formed by the mutual extrusion of these two elastic valve flaps is in the shape of a "one"; the shape of the slit can also be in the shape of a "cross", that is, the flow control structure 210 includes four elastic valve flaps, and the slit formed by the mutual extrusion of these four elastic valve flaps is in the shape of a "cross"; the shape of the slit can also be in the shape of a "Y", that is, the flow control structure 210 includes three elastic valve flaps, and the slit formed by the mutual extrusion of these three elastic valve flaps is in the shape of a "Y". The number of elastic valve flaps and the shape of the slit can be adjusted according to requirements and are not limited herein.

[0049] Preferably, the material of the water inlet head 200 is silicone, and the flow control structure 210 is made by a punching process. The flow control structure 210 includes a slit formed by punching the water inlet head 200. It can be understood that, by utilizing the characteristics of silicone, the hole wall of the hole formed by punching the water inlet head 200 will be extruded toward the hole axis to form a slit; the shape of the slit can be changed by adjusting the punching process.

[0050] It should be noted that the water flow rate when the slit formed by the multiple elastic valve flaps of the flow control structure 210 is opened can be changed by adjusting the number of elastic valve flaps and changing the cutting shape of the water inlet head 200 by the cutting process, so as to change the water output of the nipple.

[0051] It should also be noted that the flow control straw is installed in the milk bottle. Since the slit needs a certain pressure to be opened, the pressure difference caused by the baby's sucking can open the slit, enabling the liquid in the milk bottle to enter the flow control straw through the slit; therefore, the slit also has a certain anti-spray function. When the milk bottle is static or shaken, if the pressure of the liquid in the bottle on the slit does not reach the pressure required to open the slit, the liquid in the milk bottle will not flow out, playing an anti-spray role.

[0052] Preferably, the water inlet head 200 and the connecting pipe 100 are detachably connected, that is, the water inlet head 200 with different numbers of elastic valve flaps or different-shaped slits can be replaced according to requirements, so as to control the water flow rate entering the connecting pipe 100. It can be understood that as the baby grows, the amount of milk the baby needs to drink will gradually increase, so the water inlet head 200 with a larger water flow rate can be replaced to meet the baby's drinking needs.

[0053] According to some embodiments of the present invention, referring to Figure 8 and Figure 9, the direction of the arrow in the figure is the water flow direction. An anti-spray arc film 220 is provided inside the connecting pipe 100. The anti-spray arc film 220 is elastic and bent towards the water inlet direction. The anti-spray arc film 220 is provided with a plurality of micro-holes, and the liquid can pass through the micro-holes through the anti-spray arc film 220; when the pressure of the liquid on the anti-spray arc film 220 is greater than a preset value, the anti-spray arc film 220 is squeezed upward by the liquid to close the micro-holes.

[0054] It can be understood that when the flow control straw is installed on the milk bottle, when the air pressure in the bottle body 300 of the milk bottle increases due to too high liquid temperature, it is possible that the liquid sprays out from the nipple 310 after passing through the flow control straw. When the liquid moves upward in the connecting pipe 100, the liquid exerts an upward force on the anti-spray arc film 220, resulting in a reduction in the arc length of the anti-spray arc film 220, and the micro-holes of the anti-spray arc film 220 are gradually squeezed smaller and closed, so that the liquid cannot spray out.

[0055] According to some embodiments of the present invention, referring to Figures 1 to 4 , a first hollow hemisphere 120 is provided at the lower end of the connecting pipe 100. The opening of the first hollow hemisphere 120 faces downward and is communicated with the inner cavity of the connecting pipe 100. An inwardly protruding first annular convex block 130 is provided on the inner side wall of the first hollow hemisphere 120; the water inlet head 200 protrudes upward to form a boss 230, and a first annular clamping groove 240 is provided on the outer peripheral wall of the boss 230; when the first hollow hemisphere 120 is sleeved on the boss 230, the first annular convex block 130 is clamped with the first annular clamping groove 240, the inner cavity of the water inlet head 200 is communicated with the inner cavity of the connecting pipe 100, the flow control structure 210 is located below the water inlet head 200, and the liquid can enter the inner cavity of the water inlet head 200 through the flow control structure 210, and then the liquid enters the inner cavity of the connecting pipe 100 and is discharged from the water outlet part 110.

[0056] It can be understood that when the flow control structure 210 is damaged and ineffective, the water inlet head 200 can be replaced to avoid replacing the entire flow control straw to save costs; or, the water inlet head 200 with different numbers of elastic valve flaps or with dark seams of different shapes can be replaced according to requirements, so as to control the water flow rate entering the connecting pipe 100.

[0057] Preferably, an annular gravity block 250 is provided inside the water inlet head 200. When the flow control straw is installed on the milk bottle, when using the milk bottle to drink milk or water, the liquid will flow under the action of gravity, and the annular gravity block 250 can make the water inlet head 200 of the flow control straw always be located in the liquid to facilitate sucking the liquid in the milk bottle.

[0058] According to some embodiments of the present invention, referring to Figures 5 to 7, a spherical portion 140 is provided at the lower end of the connecting pipe 100. The inner cavity of the connecting pipe 100 penetrates downward through the spherical portion 140. An outwardly protruding second annular protrusion 150 is provided on the outer peripheral wall of the spherical portion 140; the water inlet head 200 is in the shape of a hollow hemisphere, and a second annular clamping groove 260 is provided on the inner side wall of the water inlet head 200; when the water inlet head 200 is sleeved on the spherical portion 140, the second annular protrusion 150 is clamped with the second annular clamping groove 260, and the flow control structure 210 is located on the lower side of the water inlet head 200, and the liquid can enter the inner cavity of the connecting pipe 100 through the flow control structure 210 and then be discharged from the water outlet portion 110.

[0059] It can be understood that when the flow control structure 210 is damaged and ineffective, the water inlet head 200 can be replaced to avoid replacing the entire flow control straw to save costs; or, the water inlet head 200 with different numbers of elastic valve flaps or dark seams with different shapes can be replaced according to needs, so as to control the water flow rate entering the connecting pipe 100.

[0060] Preferably, an annular gravity block 250 is provided in the spherical portion 140. When the flow control straw is installed on the milk bottle, when using the milk bottle to drink milk or water, the liquid will flow under the action of gravity, and the annular gravity block 250 can make the water inlet head 200 of the flow control straw always be in the liquid to facilitate sucking the liquid in the milk bottle.

[0061] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 , the milk bottle includes a bottle body 300, a nipple 310 and a flow control straw. The nipple 310 is detachably connected to the bottle body 300. A third annular protrusion 320 is provided on the inner side of the nipple 310. A third annular clamping groove 160 is provided on the outer peripheral wall of the water outlet portion 110 of the flow control straw. The third annular protrusion 320 and the third annular clamping groove 160 can be clamped to fix the flow control straw in the milk bottle.
