Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of daily necessities, and specifically relates to a constant pressure water bottle. Background Art
[0002] At present, water bottles for children to drink water on the market generally use straws. When hot water is poured into the water bottle, the hot water will heat the air in the water bottle, causing the air pressure in the water bottle to increase, which will cause the water in the water bottle to overflow through the straw, causing inconvenience in use; some water bottles have anti-overflow devices at the water inlet. When the air pressure is high, the water in the water bottle cannot overflow from the water inlet through the straw, but when the child takes the first sip of water, the water flow is very large, which can easily cause the child to choke.
[0003] Therefore, it is very necessary to design a constant pressure water bottle so that young children are not easily choked. Utility Model Content
[0004] The purpose of the present invention is to provide a constant pressure water bottle to solve the above problems existing in the prior art.
[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a constant pressure water bottle, comprising a bottle body, a bottle cap, a suction nozzle and a ventilation device, wherein the ventilation device comprises an air flow channel arranged on the bottle cap, and an air outlet and an air inlet are arranged in the air flow channel.
[0006] The air flow channel, the air outlet and the air inlet are arranged so that the air inside and outside the water bottle can circulate, thereby maintaining a constant air pressure inside the water bottle and preventing the child from being choked.
[0007] Preferably, the air outlet hole and the air inlet hole both include a free end and a fixed end, the free end of the air outlet hole extends toward the outside of the bottle cap, and the free end of the air inlet hole extends toward the inside of the bottle cap.
[0008] By setting the free ends and fixed ends of the air outlet and the air inlet, when the air pressure inside the water bottle is higher than the external atmospheric pressure, the internal air pressure will squeeze the free end of the air outlet, so that the air outlet is in an open state, and the air in the water bottle is discharged outside the water bottle, so that the air pressure inside and outside the water bottle is consistent, and the air pressure is kept constant; when the air pressure inside the water bottle is lower than the outside, the external air pressure will squeeze the free end of the air inlet, so that the air inlet is in an open state, and the air outside the water bottle enters the water bottle, so that the air pressure inside and outside the water bottle is consistent, and the air pressure is kept constant; when there is no pressure difference between the inside and outside of the water bottle, the free ends of the air outlet and the air inlet are in a closed state, preventing impurities or bacteria outside the water bottle from entering the water bottle, causing the water inside the water bottle to be polluted, which is not conducive to the health of young children; at the same time, preventing the water inside the water bottle from flowing out.
[0009] Preferably, the air outlet and the air inlet become thinner from the fixed end to the free end.
[0010] The air outlet and the air inlet are arranged to be thinner from the fixed end to the free end, so that the free ends of the air outlet and the air inlet are easier to open under the pressure difference between the inside and outside of the water bottle.
[0011] Preferably, there is one air flow channel, and the air outlet and the air inlet are arranged in the air flow channel.
[0012] Preferably, a baffle is provided on one side of the free end of the air outlet
[0013] By setting the baffle, when the external air pressure is greater than the internal air pressure, the air outlet will not be affected by the external air pressure and will remain in an open state, which is more conducive to the independent operation of the air outlet and the air inlet.
[0014] Preferably, two air flow channels are provided, and the air outlet holes and the air inlet holes are respectively provided in the corresponding air flow channels.
[0015] By setting two air flow channels, the air outlet and the air inlet are set separately, so that the air outlet and the air inlet do not affect each other when working.
[0016] Preferably, the air outlet and the air inlet are made of elastic material.
[0017] By setting the elastic material, the free ends of the air outlet and the air inlet are easier to open under the action of the air pressure difference inside and outside the water bottle. When there is no air pressure difference inside and outside the water bottle, the free ends of the air outlet and the air inlet return to a closed state, preventing impurities or bacteria outside the water bottle from entering the water bottle, causing the water inside the water bottle to be contaminated, which is not conducive to the health of young children.
[0018] Preferably, the suction nozzle is arranged directly above the bottle cap and is integrally connected to the bottle cap.
[0019] Preferably, an anti-overflow device is also provided in the suction nozzle.
[0020] The anti-overflow device is provided to prevent the water inside the water bottle from flowing out of the water bottle, and at the same time, prevent the impurities or bacteria outside the water bottle from entering the water bottle, causing the water inside the water bottle to be polluted, which is not conducive to the health of young children.

The setting of the conical thin film structure of the air outlet 5 which opens upward makes it easier for the air inside the water bottle to be discharged, and the setting of the conical thin film structure of the air inlet 6 which opens downward makes it easier for the air outside the water bottle to enter the water bottle. In the present embodiment, there is one air flow channel 4, and the air outlet 5 and the air inlet 6 are arranged in the air flow channel 4. A baffle 7 is arranged on one side of the free end of the air outlet 5. The setting of the baffle 7 reduces the opening area of the air flow channel 4. If the opening area is too large, dirt and pollution are easily hidden in the air flow channel 4.
[0029] When the air pressure inside the water bottle is higher than the external atmospheric pressure, the internal air pressure will squeeze the free end of the air outlet hole 5 open, so that the air outlet hole 5 is in an open state, and the air in the water bottle is discharged out of the water bottle through the air outlet hole 5 and the air flow channel 4, so that the air pressure inside and outside the water bottle is consistent and the air pressure is kept constant; when the air pressure inside the water bottle is lower than the external atmospheric pressure, the external air pressure will squeeze the free end of the air inlet hole 6 open, so that the air inlet hole 6 is in an open state, and the air outside the water bottle enters the water bottle through the air inlet hole 6 and the air flow channel 4, so that the air pressure inside and outside the water bottle is consistent and the air pressure is kept constant; when there is no air pressure difference between the inside and outside of the water bottle, the free ends of the air outlet hole 5 and the air inlet hole 6 are in a closed state, preventing impurities or bacteria outside the water bottle from entering the water bottle, causing the water inside the water bottle to be polluted, which is not conducive to the health of the children; at the same time, preventing the water inside the water bottle from flowing out; through the arrangement of the air flow channel 4, the air outlet hole 5 and the air inlet hole 6, the air pressure inside and outside the water bottle can be kept constant, avoiding the children from choking on water.
[0030] Specifically, the air outlet 5 and the air inlet 6 are made of elastic material, such as silicone, rubber, etc.
[0031] By setting the elastic material, the free ends of the air outlet 5 and the air inlet 6 are easier to open under the action of the air pressure difference inside and outside the water bottle.
