Description

Technical Field

[0001] The invention relates to the technical field of feeding bottle exhaust valves, and in particular to an exhaust valve assembly for a baby feeding bottle. Background Art

[0002] A milk bottle is a necessary appliance for modern infants to drink milk or milk powder. However, the conventional milk bottles currently sold on the market have a milk outlet that is also a channel for replenishing air. Therefore, when infants drink milk, they cannot replenish air in time, which can easily cause poor milk sucking and make it easy for infants to inhale air, resulting in bloating and milk spitting after drinking milk.

[0003] For example, a milk bottle anti-flatulence exhaust valve of "CN208003115U" has a nipple fixing ring in the middle of the upper part of the exhaust valve, a straw connector in the middle of the bottom of the exhaust valve, an annular protrusion on the upper edge of the exhaust valve, an air return groove on the protrusion, an air valve on the upper part of the exhaust valve, and the air valve connects the air return groove with the inside of the milk bottle. The milk bottle anti-flatulence exhaust valve has good air return performance and good sealing performance, and is not easy to leak milk;

[0004] However, in the prior art, most milk bottles are equipped with an air inlet valve, which is used to allow gas to enter the milk bottle when drinking milk, so as to supplement the negative pressure inside the milk bottle caused by the milk being sucked out. This helps to prevent the milk from flowing poorly and prevent the baby from feeling uncomfortable due to insufficient suction. However, there are very few exhaust valves. When the temperature inside the milk bottle is high, the pressure inside the milk bottle is high. At this time, people need to unscrew the bottle cap to release the pressure inside the milk bottle to prevent the milk bottle from deforming due to temperature changes or milk overflowing. After each hot milk powder is prepared, people need to open the bottle cap to release the gas in the milk bottle before giving it to the baby. If you forget to exhaust the gas, it is easy to cause the baby to choke on the milk. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the prior art that after hot milk powder is prepared, people need to open the bottle cap of the milk bottle to release the gas in the milk bottle before giving it to the baby. If the gas is forgotten, the baby may choke on the milk.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an exhaust valve assembly for a baby bottle, comprising a shell, a mounting block, an air inlet pipe and an exhaust mechanism, wherein an air inlet hole is provided at one end of the shell, and an end of the shell away from the air inlet hole is used for assembly with a bottle body through a mounting block, the shell is provided with a plurality of and evenly arranged on the side wall of the bottle body, the air inlet pipe is arranged at the center position inside the shell, one end of the air inlet pipe is sealed and connected with the air inlet hole, and a sleeve is provided at the other end of the air inlet pipe for sealing and rotation, the exhaust mechanism comprises a buoy, a float and a sealing plate, the lower part of the buoy is in a funnel-shaped structure and the lower end is connected with the sleeve, the lower end of the float is adapted to the lower part of the buoy, the upper end of the float is assembled and connected with one end of the sealing plate through a connecting piece, the sealing plate is inclined and the end away from the connecting piece is assembled and connected with the inner wall of the upper end of the buoy, the end of the buoy close to the sealing plate is connected with an exhaust pipe, an outer tube is provided at the center position of the mounting block, and one end of the outer tube is arranged in the shell and is sealed and connected with the output end of the exhaust pipe, and the shell is filled with liquid.

[0007] As a preferred embodiment, one end of the shell with the air inlet is recessed inwardly, and silicone petals are symmetrically arranged inside the end of the air inlet pipe connected to the shell, and the air inlet is formed between the two silicone petals. The two silicone petals are squeezed against each other in a normal state to form a good sealing effect. When the air pressure in the bottle body is high, the gas enters from the air inlet and squeezes the two silicone petals to expand a certain distance to facilitate the entry of gas.

[0008] As a preferred embodiment, the lower end of the float is connected to a connecting ring through a silicone tube, and the connecting ring is connected to the sleeve sealing assembly. The silicone tube is relatively soft and can bend and deform at an angle. When the bottle body is tilted at an angle, the float can rotate around the air inlet pipe through the sleeve, and can also be tilted left and right through the silicone tube, so that the float is always on the liquid surface.

[0009] As a preferred embodiment, the sleeve is open at one end, and the open end of the sleeve is sealingly and rotatably sleeved on the end face of the intake pipe. The outer tube is sealed and rotatably sleeved on one end inside the shell. The lower end of the exhaust pipe is sealingly connected to the end sleeve. The outer end of the sleeve is assembled and connected to the end sleeve via a connecting shaft. The sleeve and the intake pipe are rotated together to realize the rotation angle of the float as the liquid level in the shell changes. By arranging a connecting shaft between the end sleeve and the sleeve, the stability of the intake pipe and the float arranged on the intake pipe can be ensured.

[0010] As a preferred embodiment, the upper middle part of the interior of the buoy is arranged in a square structure, an end plate is arranged on one side of the upper end of the buoy, one end of the exhaust pipe passes through the end plate and is connected with the interior of the buoy, an upper plate is arranged at the upper end of the interior of the buoy, one end of the sealing plate is sealed and connected with the lower end of the upper plate, through the end plate, a hole is arranged under the end plate for connecting with the exhaust pipe, so that the gas exhausted from the upper end of the buoy can be discharged from the exhaust pipe, and the upper plate is arranged to squeeze the sealing plate lifted to the top and the upper plate to achieve a sealing effect, even if milk enters the buoy, it is difficult to pass through the sealing plate and be discharged.

[0011] As a preferred embodiment, the lower half of the sealing plate is inclinedly assembled with the buoy, and the upper half of the sealing plate is a soft silicone structure. The inner wall of the buoy on the side of the sealing plate close to the end plate is provided with a side plate, and the side plate is sealingly connected to the sealing plate. By providing a soft structure above the sealing plate, when the float moves downward, the sealing plate can be pulled to bend and create space between the upper plate for exhausting gas. When the float moves upward, the sealing plate is squeezed to move upward until the sealing plate is against the bottom of the upper plate. At this time, the upper edge of the sealing plate is squeezed and sealed with the side plate.

[0012] As a preferred embodiment, the connecting part includes a telescopic plate and a soft belt, the telescopic plate is a hollow plate-like structure, the upper end of the telescopic plate is rotatably connected to the upper end of the sealing plate, and the lower end of the telescopic plate is connected to the float assembly through a soft belt. Through the arrangement of the telescopic plate, when the float moves upward, the telescopic plate can be squeezed to the shortest state, and the telescopic plate can squeeze the upper end of the sealing plate upward until it is sealed with the upper plate.

[0013] As a preferred embodiment, bubbles are provided in the side wall of the buoy, and a plurality of bubbles are provided and evenly distributed on the side wall of the buoy. By evenly arranging a plurality of bubbles on the side wall of the buoy, the buoy can float more lightly in the liquid.

[0014] As a preferred embodiment, a mounting groove is provided on the upper side of the feeding bottle body, one end of the outer tube passes through the mounting groove and extends to the inner wall of the outer shell, and the outer tube is fixedly connected to the outer shell.

[0015] As a preferred embodiment, the mounting block is in an I-shaped structure, the mounting block is inserted into the mounting groove, the mounting block is in a hollow structure, the outer wall of one end of the outer tube is rotatably connected to one end of the mounting block arranged inside the bottle body, and when installing the exhaust valve, the mounting block is pre-assembled on the mounting groove, and one end of the outer tube is rotatably connected to the internal thread of the mounting block, so that the outer wall of the outer shell is firmly fitted with the inner wall of the bottle body, wherein the outer tube is fixedly connected to the outer shell.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are:

[0017] 1. When the present invention exhausts gas, excess gas enters the air inlet pipe through the air inlet hole, passes through the sleeve connected to the air inlet pipe and enters the interior of the float from below. In this state, the gas pushes the float upward to push the float open, so that a gap is left between the float and the float. The gas passes through the gap and the sealing plate and is discharged from the exhaust pipe. The gas discharged from the exhaust pipe is discharged from the outside of the bottle body through the outer tube. Since the outer shell is filled with liquid, the liquid height can keep the float always floating on the liquid surface, so that the baby can exhaust gas normally when using the bottle body or when the bottle body is placed flat and still.

[0018] 2. The present invention provides a plurality of exhaust valves on the milk bottle body. When the milk bottle body is tilted for use, one exhaust valve is in a state of not being completely immersed in milk. Since the exhaust valve is used for normal exhaust of gas, the air inlet end of the other exhaust valve is immersed in the milk. The air pressure in the milk bottle squeezes a portion of the milk into the buoy. The buoy is always in an upright state. The milk squeezes the float from the lower end of the buoy and enters the buoy. The float floats above the milk. When there is more milk, the float moves upward and squeezes the sealing plate to rotate upward until the sealing plate is sealed with the inner wall of the buoy. The milk cannot pass through the sealing plate and be discharged from the exhaust pipe. When the exhaust valve rotates to the top of the milk bottle body and exhaust work is performed without contact with the milk, the gas enters the buoy and floats to the top of the milk that has entered the buoy before. As the gas gradually increases, the milk is squeezed downward and finally discharged from the inlet pipe into the milk bottle body. After the milk in the buoy drops, the float drops accordingly, the sealing plate opens, and the gas passes through the sealing plate and is discharged.

[0019] 3. The present invention realizes the rotation angle of the float bucket along with the change of the liquid level in the shell by the rotational coordination of the sleeve and the air inlet pipe. The stability of the air inlet pipe and the float bucket arranged on the air inlet pipe can be ensured by arranging a connecting shaft between the end sleeve and the sleeve.

[0020] 4. The telescopic plate provided in the present invention can squeeze the telescopic plate to shrink to the shortest state when the float moves upward, and the telescopic plate can squeeze the upper end of the sealing plate to move upward until it is sealed with the upper plate.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 9The present invention provides a technical solution: an exhaust valve assembly for a baby bottle, comprising a shell 1, a mounting block 2, an air inlet pipe 3 and an exhaust mechanism, wherein an air inlet hole 4 is provided at one end of the shell 1, and an end of the shell 1 away from the air inlet hole 4 is used for assembly with a bottle body 5 through a mounting block 2, the shell 1 is provided with a plurality of air inlet pipes 3 which are evenly arranged on the side wall of the bottle body 5, the air inlet pipe 3 is arranged at the center position inside the shell 1, one end of the air inlet pipe 3 is sealed and connected with the air inlet hole 4, and the other end of the air inlet pipe 3 is sealed and rotatably provided with a sleeve 6, and the exhaust mechanism comprises a float 711, a float 712 and a sealing plate 713, The lower part of the interior of the buoy 711 is in a funnel-shaped structure and the lower end is connected to the sleeve 6. The lower end of the float 712 is adapted to the lower part of the interior of the buoy 711. The upper end of the float 712 is assembled and connected to one end of the sealing plate 713 through the connecting piece 8. The sealing plate 713 is inclined and the end away from the connecting piece 8 is assembled and connected to the inner wall of the upper end of the buoy 711. The end of the buoy 711 close to the sealing plate 713 is connected to the exhaust pipe 9. An outer tube 10 is provided at the center of the mounting block 2. The outer tube 10 is arranged in the outer shell 1 and one end is sealed and connected to the output end of the exhaust pipe 9. The interior of the outer shell 1 is filled with liquid.

[0034] like Figure 1-Figure 9 As shown, one end of the shell 1 with the air inlet 4 is recessed inwardly, and silicone petals 11 are symmetrically arranged inside the end where the air inlet pipe 3 is connected to the shell 1, and the air inlet 4 is formed between the two silicone petals 11. The two silicone petals 11 are squeezed against each other in a normal state to form a good sealing effect. When the air pressure in the bottle body 5 is relatively high, the gas enters from the air inlet 4 and squeezes the two silicone petals 11 to expand a certain distance, which is convenient for the gas to enter.

[0035] like Figure 1-Figure 9 As shown, the lower end of the float 711 is connected to a connecting ring 122 through a silicone tube 121, and the connecting ring 122 is sealed and assembled with the sleeve 6. The silicone tube 121 is set, and the material of the silicone tube 121 is relatively soft and can be bent and deformed at an angle. When the bottle body 5 is skewed at an angle, the float 711 can rotate around the air inlet pipe 3 through the sleeve 6, and can also be skewed left and right through the silicone tube 121, so that the float 711 is always on the liquid surface.

[0036] like Figure 1-Figure 9 As shown, the sleeve 6 is open at one end, and the open end of the sleeve 6 is sealed and rotatably sleeved with the end face of the intake pipe 3. The outer tube 10 is sealed and rotatably sleeved at one end inside the shell 1, and the lower end of the exhaust pipe 9 is sealed and connected to the end sleeve 13. The outer end of the sleeve 6 is assembled and connected to the end sleeve 13 through a connecting shaft 14. Through the rotational cooperation of the sleeve 6 and the intake pipe 3, the float 711 can rotate with the change of the liquid level in the shell 1. By arranging the connecting shaft 14 between the end sleeve 13 and the sleeve 6, the stability of the intake pipe 3 and the float 711 arranged on the intake pipe 3 can be ensured.

[0037] like Figure 1-Figure 9 As shown, the upper middle part of the interior of the buoy 711 is arranged in a square structure, an end plate 151 is arranged on one side of the upper end of the buoy 711, one end of the exhaust pipe 9 passes through the end plate 151 and is connected with the interior of the buoy 711, an upper plate 152 is arranged at the upper end of the interior of the buoy 711, one end of the sealing plate 713 is sealed and connected with the lower end of the upper plate 152, through the end plate 151, a hole is arranged below the end plate 151 for connecting with the exhaust pipe 9, so that the gas exhausted from the upper end of the buoy 711 can be discharged from the exhaust pipe 9, and the upper plate 152 is arranged to squeeze the sealing plate 713 lifted to the top and the upper plate 152 to achieve a sealing effect, even if milk enters the buoy 711, it is difficult to pass through the sealing plate 713 and be discharged.

[0038] like Figure 1-Figure 9 As shown, the lower half of the sealing plate 713 is obliquely assembled with the buoy 711, and the upper half of the sealing plate 713 is a soft silicone structure. The inner wall of the buoy 711 on the side of the sealing plate 713 close to the end plate 151 is provided with a side plate 16, and the side plate 16 is sealed and connected to the sealing plate 713. By using the soft structure provided above the sealing plate 713, when the float 712 moves downward, the sealing plate 713 can be pulled to bend and create space between the upper plate 152 for exhausting gas. When the float 712 moves upward, the sealing plate 713 is squeezed to move upward until the sealing plate 713 is abutted against the bottom of the upper plate 152. At this time, the upper edge of the sealing plate 713 is squeezed and sealed with the side plate 16.

[0039] like Figure 1-Figure 9 As shown, the connecting member 8 includes a telescopic plate 171 and a soft belt 172. The telescopic plate 171 is a hollow plate-like structure. The upper end of the telescopic plate 171 is rotatably connected to the upper end of the sealing plate 713, and the lower end of the telescopic plate 171 is assembled and connected to the float 712 through the soft belt 172. Through the arrangement of the telescopic plate 171, when the float 712 moves upward, the telescopic plate 171 can be squeezed to contract to the shortest state, and the telescopic plate 171 can squeeze the upper end of the sealing plate 713 to move upward until it is sealed with the upper plate 152.

[0040] like Figure 1-Figure 9 As shown, a floating bubble 18 is provided in the side wall of the buoy 711. A plurality of floating bubbles 18 are provided and are evenly distributed on the side wall of the buoy 711. By evenly arranging a plurality of floating bubbles 18 on the side wall of the buoy 711, the buoy 711 can float more lightly in the liquid.

[0041] like Figure 1-Figure 9 As shown, a mounting groove 19 is provided on the top of the feeding bottle body 5 , one end of the outer tube 10 passes through the mounting groove 19 and extends to the inner wall of the outer shell 1 , and the outer tube 10 is fixedly connected to the outer shell 1 .

[0042] like Figure 1-Figure 9As shown, the mounting block 2 is an I-shaped structure, the mounting block 2 is inserted into the mounting groove 19, the mounting block 2 is a hollow structure, the outer wall of one end of the outer tube 10 is threadedly connected to the end of the mounting block 2 arranged inside the bottle body 5, when installing the exhaust valve, the mounting block 2 is pre-assembled on the mounting groove 19, and one end of the outer tube 10 is threadedly connected to the inner wall of the mounting block 2, so that the outer wall of the shell 1 and the inner wall of the bottle body 5 are firmly fitted.

[0043] Working principle: The outer shell 1 is assembled and set on the bottle body 5 through the mounting block 2, so that the outer shell 1 is inside the bottle body 5, which can effectively prevent the baby from pressing the outer shell 1 for a long time when feeding, causing the outer shell 1 to be damaged. After the milk is filled in the bottle body 5, the temperature inside the bottle body 5 is high, resulting in a large pressure, and it is necessary to discharge excess gas to the outside. When exhausting, the excess gas enters the air inlet pipe 3 through the air inlet hole 4, passes through the sleeve 6 connected to the air inlet pipe 3, and enters the interior of the buoy 711 from below. In this state, the gas pushes the float 712 upward to make the float 712 12 is opened, so that there is a gap between the float 712 and the float 711, and the gas passes through the gap and the sealing plate 713 to be discharged from the exhaust pipe 9, and the gas discharged from the exhaust pipe 9 is discharged from the outside of the feeding bottle body 5 through the outer tube 10. Since the shell 1 is filled with liquid, the height of the liquid can keep the float 711 always floating on the liquid surface, so that the baby can exhaust normally when using the feeding bottle body 5 or when the feeding bottle body 5 is placed flat and still. By arranging multiple exhaust valves on the feeding bottle body 5, when the feeding bottle body 5 is tilted for use, there will be an exhaust valve in the state where it is not filled with milk. The exhaust valve is used to discharge gas normally, and the air inlet end of the other exhaust valve is immersed in the milk. The air pressure in the feeding bottle squeezes a part of the milk into the buoy 711. The buoy 711 is always in an upright state. The milk squeezes the float 712 from the lower end of the buoy 711 into the buoy 711. The float 712 floats above the milk. When there is more milk, the float 712 moves up and squeezes the sealing plate 713 to rotate upward until the sealing plate 713 is sealed with the inner wall of the buoy 711, and the milk cannot pass through the sealing plate 713 and be discharged from the exhaust pipe 9. When the air valve rotates to the top of the milk bottle body 5 and the exhaust work is performed without contact with the milk, the gas enters the buoy 711 and floats to the top of the milk that has previously entered the buoy 711. As the gas gradually increases, the milk is squeezed downward and finally discharged from the inlet pipe into the milk bottle body 5. After the milk in the buoy 711 drops, the float 712 drops accordingly, the sealing plate 713 opens, and the gas passes through the sealing plate 713 and is discharged. After the milk bottle body 5 is used, the exhaust valve can be disassembled through the mounting block 2, and the air inlet pipe 3 can be injected with pure water to rinse it, and then injected with gas to blow it dry.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
