Description

Technical Field

[0001] The present invention relates to the technical field of mother and baby products, and particularly relates to an anti-spray device and a feeding bottle. Background Art

[0002] At present, there are various types of sippy cups or feeding bottles with a sipping spout on the market. By connecting the sipping spout to the cup or bottle, infants and young children are trained to eat independently. Usually, the water outlet of the sipping spout is a single flat structure with simple functions. When the water or milk in the feeding bottle or cup has a temperature exceeding 40°C, the air pressure in the bottle or cup gradually increases with the continuously evaporating water vapor, which easily causes the water or milk to spray out. The user is easily scalded by the sprayed hot liquid, presenting a certain safety hazard. Or when the feeding bottle or cup is vibrated or shaken, the water or milk in the bottle or cup will also spray out, resulting in a poor user experience for consumers. Summary of the Invention

Detailed implementation manners

[0030] The embodiments of the present invention provide a new type of baby bottle to solve the technical problem that there is still liquid flowing out when infants and young children stop sucking in the prior art.

[0031] In order to make the objectives, features, and advantages of the present invention more obvious and understandable, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] Figure 1 A blowout preventer provided for the embodiment of the present invention. Specifically, as Figures 2 - 4 shown, the blowout preventer 3 includes an upper cover leaf 31, a silica gel leaf 32, and a lower cover leaf 33. Among them, the upper cover leaf 33 includes a first connecting portion 313. An air groove 311 extending to the edge of the upper cover leaf 31 is provided on the outer side wall of the first connecting portion 313, and a first connecting pipe 312 is provided within the area of the first connecting portion 313. The first connecting pipe 312 communicates with the first connecting portion 313. In this embodiment, the upper cover leaf 31 is further provided with a second connecting portion 314; a groove 326 is provided on the first surface 325 of the silica gel leaf 32. The groove 326 and the bottom of the first connecting portion 313 form a first chamber 6. The first chamber 6 communicates with the outside through the air groove 311. A longitudinally extending valve 321 and a through hole are provided on the groove 326, and the first connecting pipe 312 passes through the through hole. In this embodiment, the through hole is a longitudinally extending third connecting pipe 322; the lower cover leaf 33 is provided with a second groove 331 and a second connecting pipe 332. A first stepped surface 333 protruding radially inward is provided on the inner side wall of the second connecting pipe 332. In this embodiment, the first stepped surface 333 is inclined downward from top to bottom and from the outer circle to the inner circle. And when the lower cover leaf 33 and the silica gel leaf 32 are assembled together, the upper end opening 3331 of the second connecting pipe 332 fits with the second surface 327 of the silica gel leaf 32, and the fitting position corresponds to the groove 326 on the first surface 325. Of course, in other embodiments, as Figure 5 shown, the first stepped surface 333 is horizontally arranged.

[0034] Particularly, the valve 321 can be hermetically abutted against the lower surface 3332 of the first stepped surface 333, so that a second chamber 10 is formed between the first stepped surface 333 and the silica gel leaf 32, and the straw 4 is blocked from the second chamber 10. In this embodiment, the material of the silica gel leaf 32 is silica gel. Therefore, when the upper cover leaf 31 and the lower cover leaf 33 are assembled with the silica gel leaf 32, a sealed connection can be formed between them.

[0035] Further, in this embodiment, to ensure that the valve 321 can move smoothly under the action of the air pressure difference, when the silica gel blade 32 is installed together with the lower cover blade 33, the valve 321 is in sealing contact with the lower surface of the first step surface 333. An inclined surface 324 is formed on the first surface 325 of the silica gel blade 32. The inclined surface 324 surrounds the valve 321 and is inclined from top to bottom and from the outer circle to the inner circle. When the infant sucks the nipple, only a small amount of force is required to move the valve 321 towards the bottle body 1, and the liquid in the bottle body 1 can be sucked. Particularly, when the first step surface 333 is inclined from top to bottom and from the outer circle to the inner circle, when the valve 321 drives the inclined surface 324 towards the bottle body 1, to prevent the inclined surface 324 from fitting together with the upper end opening of the first step surface 333 and closing the second chamber 10, the inclination angle of the inclined surface 324 is smaller than the inclination angle of the first step surface 333. Of course, in other embodiments, such as Figure 6 shown, when the valve 321 is in sealing contact with the lower surface of the first step surface 333, the groove 326 of the silica gel blade 32 is set as a horizontal plane.

[0036] Embodiment Two:

[0037] This embodiment provides a baby bottle, including the anti-spray device in Embodiment One, as Figure 7 shown, the baby bottle includes a bottle body 1, a nipple 2, and a straw 4. The nipple 2 is connected to the bottle body 1 through the anti-spray device 3. Specifically, when connecting the anti-spray device 3 to the bottle body 1, the lower cover blade 33 is inserted into the bottle body 1, and the edge of the silica gel blade 32 is pressed against the opening end of the bottle body 1, playing a role of limiting and sealing. The connecting member 7 fixes the anti-spray device 3 on the bottle body 1. Further, the second connecting portion 314 is inserted into the nipple 2 and forms a chamber 5 with the nipple 2. The second groove 331 is communicated with the chamber 5 through the first connecting pipe 312. In this embodiment, the third connecting pipe 322 is inserted into the second groove 331 to connect the first connecting pipe 312 with the chamber 5, and the second groove 331 is communicated with the second chamber 10, so that the second chamber 10 is communicated with the chamber 5.

[0038] As Figures 8 - 9As shown, when an infant sucks on the nipple 2, the air pressure inside the nipple 2 decreases. Since the nipple 2 is connected to the second chamber 10, the air pressure in the second chamber 10 also decreases. And since the first chamber 6 is connected to the external environment, there is an air pressure difference between the first chamber 6 and the second chamber 10. At this time, the valve 321 moves towards the bottle body 1 and separates from the lower surface 3332 of the first step surface 333, enabling the second chamber 10 to communicate with the straw 4. Consequently, the bottle body 1 communicates with the second chamber 10, and the liquid in the bottle body 1 enters the second chamber 10 through the straw 4, then enters the second groove 331, and enters the nipple 2 through the first connecting pipe 312. When the infant stops sucking, the external atmosphere enters the second chamber 10 through the nipple 2, causing the air pressures in the second chamber 10 and the first chamber 6 to be the same. At this time, the valve 321 moves away from the bottle body 1 until it seals and abuts against the lower surface 3332 of the first step surface 333, sealing off the straw 4 from the second chamber 10, preventing the liquid in the bottle body 1 from flowing into the nipple 2. That is, when sucking starts, the valve 321 automatically opens, and when sucking stops, the valve 321 automatically closes, ensuring that the liquid in the bottle body 1 does not flow out spontaneously.

[0039] In this embodiment, the hardness of the silicone material of the silicone blade 32 is 50 degrees, the thickness of the groove 326 area of the silicone blade 32 is 1 mm, and the diameter of the upper end opening 3331 of the second connecting pipe 332 is 19 mm. Tests show that the larger the diameter of the upper end opening 3331 of the second connecting pipe 332, the larger the force-bearing area of the silicone blade 32 when sucking on the practice nipple 2, enabling the infant to open the valve 321 with less force.

[0040] Furthermore, as Figure 2 and Figure 4 shown, to prevent the air pressure in the bottle body 1 from decreasing when the infant sucks on the nipple 2 and causing the bottle body 1 to collapse, a one-way valve 323 is provided on the second surface 327 of the silicone blade 32, and a first opening 334 is provided on the lower cover leaf 33. When the silicone blade 32 and the lower cover leaf 33 are assembled together, the one-way valve 323 passes through the first opening 334 and is located inside the bottle body 1. As Figure 10 shown, the one-way valve 323 communicates with the first chamber 6, and the first chamber 6 is in turn connected to the external environment through the air groove 311, enabling the bottle body 1 to remain connected to the external environment through the one-way valve 323. When the air pressure in the bottle body 1 decreases due to the infant's sucking, the atmospheric pressure replenishes the gas in the bottle body 1 through the one-way valve 323. In this embodiment, the one-way valve 323 is a silicone tube, and there is a slotted cut at the tube, allowing gas to only enter the bottle body 1 through the upper end of the one-way valve 323, while the liquid in the bottle body 1 cannot leak out through the one-way valve 323. In Figures 8 - 10 the figure, the black arrow represents the liquid flow, and the white arrow represents the air flow.

[0041] In this embodiment, as Figure 4 shown, when the infant is sucking, in order to ensure that the liquid flowing through the second groove 331 can enter the nipple 2 through the first connecting pipe 312, and to prevent the liquid in the second groove 331 from being unable to be sucked due to the tight fit between the third connecting pipe 322 and the second groove 331, the second groove 331 has a radially reduced-diameter section 3311, and the inner diameter of the reduced-diameter section 3311 is smaller than the outer diameter of the third connecting pipe 322. Therefore, the third connecting pipe 322 cannot be inserted into the reduced-diameter section 3311, and there is a gap between it and the second groove 331. Figure 11 A schematic diagram of the assembly of this new type of baby bottle is provided.

[0042] Furthermore, the materials of the upper cover leaf 31 and the lower cover leaf 33 are both hard plastic materials, making this new type of baby bottle have the advantages of high temperature resistance, non-toxic and harmless. And in order to ensure that the first chamber 6 is always annularly connected to the outside world, in this embodiment, the number of air grooves 311 is four. At the same time, in order to enable the baby bottle to be drunk in any state, a gravity ball 8 is provided at the lower end of the straw 4. As Figure 12 shown, under the action of the gravity ball 8, the straw 4 can be bent in any direction, and the liquid in the bottle body 1 can be sucked in any state. Further, the gravity ball 8 includes a stainless steel bead core and a silicone rubber coating, preventing the gravity ball 8 from contacting the bottle body 1 and ensuring that the gravity ball 8 does not affect the liquid in the bottle body 1. At the same time, in this embodiment, in order to avoid the nipple 2 being contaminated, a cover 9 adapted to the nipple 2 is provided.

[0043] For the new type of baby bottle provided by the embodiment of the present invention, when the bottle body 1 is placed upside down, horizontally or in any 360° placement, the liquid in the bottle body 1 will not flow out from the nipple 2; when the bottle body 1 is vibrated or shaken, the hot liquid in the bottle body 1 will not spray out from the nipple 2 either; and the liquid flow rate of the bottle body 1 is large and the suction resistance is small. When sucking, liquid flows out, and when not sucking, the valve 321 closes and the liquid does not flow out, having an anti-spray protection effect, so that the infant will not be choked during the sucking process.

[0044] The above is the case. The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
