[0042] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of the present invention and, together with the embodiments of the present invention, serve to illustrate the principles of the present invention.

[0043] Example 1

[0044] This embodiment provides a liquid storage bottle with water-resistant and air-permeable properties, such as... Figure 1 As shown, it includes a screw cap 1, an inlet pipe 4, an outlet pipe 5, a vent 6, and a water-blocking and venting device 7; the screw cap 1 is provided with the inlet pipe 4 and the outlet pipe 5, the vent 6 is opened in the middle of the screw cap 1, and the water-blocking and venting device 7 is installed on the inner side of the middle of the screw cap 1.

[0045] The inlet pipe 4 and outlet pipe 5 of the liquid storage bottle allow liquid to be added into the bottle through the inlet pipe 4 and liquid to be drawn out of the bottle through the outlet pipe 5. The pressure change inside the bottle caused by the inlet and outlet is balanced by the vent 6. At the same time, the water-blocking and venting device 7 is used to prevent liquid from splashing out of the bottle.

[0046] Preferred, such as Figure 1 As shown, one end of the inlet pipe 4 is fixed with an inlet connector 2 that extends out of the screw cap 1.

[0047] Inlet connector 2 is used to connect to an external inlet pipeline.

[0048] Preferred, such as Figure 1 As shown, one end of the liquid outlet pipe 5 is fixed with a liquid outlet connector 3 that extends out of the screw cap 1.

[0049] The liquid outlet connector 3 is used to connect to an external liquid outlet pipeline.

[0050] Preferably, the water-blocking and air-permeable device 7 includes a shell, a membrane, and water-blocking holes; the membrane is installed on the upper part of the shell, and the membrane can separate the upper and lower parts of the internal space of the shell, and the water-blocking holes are provided on the lower part of the shell.

[0051] The shell is used to prevent splashed liquid from contacting the membrane, and the water-blocking holes are used to allow gas to flow between the inside and outside of the shell.

[0052] Preferably, the membrane is made of polytetrafluoroethylene.

[0053] Preferably, the shell and the screw cap 1 are connected by an adhesive layer.

[0054] Preferably, the lower part of the housing is provided with multiple horizontal baffles, which can separate the space on both sides of the baffles, and the baffles are provided with water-blocking holes.

[0055] The multi-stage baffle design can consume most of the potential energy of the liquid movement, preventing most of the splashed liquid from contacting the membrane.

[0056] Preferably, the diameter of the water-blocking holes in the water-blocking and air-permeable device 7 increases sequentially from top to bottom.

[0057] Preferably, the inner wall of the shell is an inverted cone shape.

[0058] Preferably, the inner wall of the screw cap 1 is covered with an adhesive strip.

[0059] Due to the surface tension of water, the water-blocking holes block the droplets from passing through in stages. Through the blocking effect of multiple water-blocking holes and the buffering effect of the inner wall of the shell, the liquid that finally adheres to the membrane is difficult to wet and block the water-blocking and breathable membrane, thereby reducing the risk of the water-blocking and breathable membrane getting wet and blocked, avoiding the failure of the liquid inlet and outlet function of the liquid storage bottle, and at the same time preventing water, dust and other substances from entering the bottle.

[0060] Example 2

[0061] This embodiment provides a liquid storage bottle with water-blocking and air-permeable properties. It is based on Embodiment 1, but the water-blocking and air-permeable device 7 has been replaced, such as... Figure 2 and Figure 3As shown, the water-blocking and air-permeable device 7 includes a water-blocking and air-permeable membrane 702, a barrel 703, an air-permeable switching component 704, a lateral air-permeable device 705, and a floating air-permeable device 706; the water-blocking and air-permeable membrane 702 is provided on the upper part of the barrel 703, the air-permeable switching component 704 is provided on the middle part of the barrel, the lateral air-permeable device 705 is provided on the lower part of the barrel, and the floating air-permeable device 706 is connected to the lower end of the barrel.

[0062] The ventilation switching component 704 is used to switch the air communication path inside and outside the barrel 703, and control whether the air inside and outside the barrel 703 circulates through the lateral ventilation device 705 or the floating ventilation device 706.

[0063] Preferred, such as Figure 4 As shown, the lateral ventilation device 705 includes a hexagonal column 7051, a hollow groove 7052, universal ball bearings 7053, universal hinge rods 7054, and a sliding plug 7055. Multiple universal ball bearings 7053 are installed on the lower end face of the hexagonal column 7051, and multiple universal hinge rods 7054 are evenly installed around the hexagonal column 7051. The other end of each universal hinge rod 7054 is equipped with a sliding plug 7055, and the sliding plug 7055 slides in the groove 7031 opened in the side wall of the cylinder.

[0064] For the six-sided prism 7051, materials with higher density are preferred, such as lead, steel, and platinum.

[0065] The universal ball bearing 7053 is used to reduce the friction between the hexagonal cylinder 7051 and the barrel 703, making it easier for the hexagonal cylinder 7051 to slide relative to the barrel 703.

[0066] Preferred, such as Figure 5 As shown, the upper end of the inner wall of the slide groove 7031 is provided with a venting groove 7032. When the slide plug 7055 is in different positions of the slide groove 7031, the venting groove 7032 can control the opening and closing of the venting and the adjustment of the venting volume.

[0067] The sliding plug 7055 and the sliding groove 7031 cooperate to make the end of the venting groove 7032 completely blocked, partially blocked and completely unblocked, respectively, so as to achieve the purpose of adjusting the ventilation capacity of the venting groove 7032.

[0068] When the liquid in the storage bottle shifts to one side due to shaking, rapid acceleration, or rapid deceleration of the bottle, the hexagonal prism 7051 slides to that side with the liquid due to inertia. Under the action of the universal ball bearing 7053 at its lower part, the hexagonal prism 7051 slides rapidly. The hexagonal prism 7051 drives the universal joint rod to slide to that side, and the universal joint rod 7054 drives the sliding plug 7055 to block the vent groove 7032 on that side, preventing the liquid from entering through the vent groove 7032 on the side of the barrel 703.

[0069] At the same time, the hexagonal column 7051 will drive the sliding plug 7055 on the other side to increase the exposed area of ​​the venting groove 7032, so as to maintain the ventilation capacity of the lateral ventilation device 705.

[0070] Preferred, such as Figure 3 As shown, the floating ventilation device 706 includes a connecting pipe and a ventilation float.

[0071] Preferably, the lower part of the ventilated float is slightly heavier than the upper part, and the vent of the ventilated float faces upward.

[0072] The vent float remains on the surface of the liquid. It is activated when the storage bottle is tilted to a certain angle. At this time, the tank 703 is surrounded by liquid. The vent hole on the vent float connects the liquid surface inside the bottle with the inside of the tank 703, serving as a backup vent.

[0073] Preferred, such as Figure 3 and Figure 4 As shown, the ventilation switching assembly 704 includes a hollow conical support ring 7041, a conical plumb bob 7042, a first connecting line 7043, a spherical plumb bob 7044, and a sealing ball 7045. The hollow conical support ring is fixed to the middle of the cylinder. The conical plumb bob 7042 is installed in the middle of the hollow conical support ring. The lower part of the conical plumb bob 7042 is connected to the spherical plumb bob 7044 through the first connecting line 7043. The lower part of the spherical plumb bob 7044 is connected to the sealing ball 7045 through the second connecting line.

[0074] When the storage bottle is tilted to a certain angle, the conical plumb bob 7042 overcomes the friction between itself and the hollow conical support ring 7041 under the action of gravity and slides to one side. At this time, the conical plumb bob 7042 pulls the spherical plumb bob 7044 through the first connecting line 7043, so that the spherical plumb bob 7044 drives the hexagonal column 7051 to be lifted towards the vent hole 6. The hexagonal column 7051 drives the sliding plug 7055 through the universal hinge rod 7054 to block all the venting slots 7032, and close the venting function of the side venting device 705. At the same time, the spherical plumb bob 7044 drives the sealing ball 7045 to move towards the vent hole 6 through the second connecting line, so that the floating venting device 706 can connect the air on the liquid surface in the storage bottle and the air in the barrel 703.

[0075] The length of the first connecting line 7043 should be sufficient to ensure that the spherical plumb bob 7044 can move horizontally with the hexagonal prism 7051 when it slides horizontally, so as to avoid the horizontal sliding of the hexagonal prism 7051 being affected by the first connecting line 7043 being too short.

[0076] Preferred, such as Figure 4 As shown, the hollow groove 7052 is provided in the middle of the hexagonal prism 7051. The lower part of the hollow groove 7052 allows the spherical plumb bob 7044 to slide, while the upper part of the hollow groove 7052 cannot allow the spherical plumb bob 7044 to pass through.

[0077] The six-sided column 7051 is a multi-layered design to accommodate the universal ball bearing 7053 and the universal hinge rod 7054.

[0078] The multi-layered structure of the six-sided prism 7051 is assembled using bolts.

[0079] Preferably, the lower part of the barrel body 703 is provided with an inverted frustum-shaped groove wall.

[0080] The inverted frustum-shaped groove wall facilitates the fit with the sealing ball 7045. When the circumference of the sealing ball 7045 is completely in contact with the inverted frustum-shaped groove wall, the gas flows through the lateral ventilation device 705. When a gap appears between the circumference of the sealing ball 7045 and the inverted frustum-shaped groove wall, the gas flows through the floating ventilation device 706.

[0081] Since liquid may enter the vent hole of the floating vent 706 when liquid splashes, we use the side vent 705 for ventilation in most cases. Only in extreme cases (including when the liquid storage bottle is tilted at too large an angle, tipped over, or inverted) will we close the side vent 705 and open the floating vent 706 for ventilation.

[0082] Preferably, the barrel body 703 and the screw cap 1 are connected by an adhesive ring 701, which is hydrophobic.

[0083] The side ventilation device 705 and the floating ventilation device 706 are designed so that when the liquid in the storage bottle splashes to one side, the ventilation slot 7032 on that side will close. When the liquid in the storage bottle vibrates up and down, the side ventilation device 705 will also close and open with the up and down splashing of the liquid to prevent the liquid from entering the tank 703. When the storage bottle is tilted or excessively tilted, the ventilation switching component 704 will control the side ventilation device 705 to completely block the ventilation holes on the side wall of the tank 703 and open the floating ventilation device 706.

[0084] By incorporating the ventilation switching component 704, the lateral ventilation device 705, and the floating ventilation device 706, the liquid storage bottle is able to maintain its ability to be permeable to air but not to water even when shaken, tilted, or tipped over.

[0085] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
