[0025] This utility model provides a liquid filling anti-overflow funnel, including a barrel plug 101, a filling funnel 102, a check valve 103, a sealing seat 104, a connecting assembly 105, and a barrel opening sealing ring 111. The connecting assembly 105 includes a mounting nut 112 and a locking nut 113, and also includes an upper sealing ring 114 and a lower sealing ring 115. The check valve 103 includes a buoyancy column 116 and a sealing ball head 117. The barrel plug 101 has a limiting protrusion 118. The sealing seat 104 includes a positioning boss 119 and a sealing pad 120. The barrel plug 101 seals the container opening. When the liquid is full, the check valve 102... 03. The rise seals the vent 110, while liquid accumulates in the filling funnel 102. At this time, rotating the filling funnel 102 causes the vent 110 and the second filling hole 109 to rotate, so that the vent 110 is connected to the first filling hole 108. This prevents the negative pressure inside the container from making the plug 101 difficult to remove. At the same time, the second filling hole 109 rotates to above the sealing seat 104, preventing the liquid in the filling funnel 102 from flowing out and facilitating the transfer of liquid. It can be understood that the above solution can be used to prevent liquid from overflowing when adding liquid to the container, and can also be used to improve the sealing effect between the plug 101 and the container.

[0026] In this specific embodiment, the liquid-adding funnel 102 is rotatably connected to the barrel stopper 101 and is disposed on the barrel stopper 101. The barrel stopper 101 has an installation chamber 106, a float hole 107, and a first liquid-adding hole 108. The float hole 107, the installation chamber 106, and the first liquid-adding hole 108 are located on the side of the barrel stopper 101 near the liquid-adding funnel 102. The float hole 107 and the first liquid-adding hole 108 penetrate the barrel stopper 101. The check float 103 is movably connected to the barrel stopper 101 and is located inside the float hole 107. The sealing seat 104 is connected to the barrel stopper 101 and is located on the barrel stopper 101 near the installation chamber. On one side of 106, the connecting component 105 is disposed on the barrel stopper 101 and connects the barrel stopper 101 and the liquid addition funnel 102. The liquid addition funnel 102 has a second liquid addition hole 109 and a vent hole 110. The second liquid addition hole 109 penetrates the liquid addition funnel 102 and communicates with the first liquid addition hole 108. The vent hole 110 penetrates the liquid addition funnel 102 and communicates with the float hole 107. The barrel stopper 101 is provided with a first mark 121 on the side near the check float 103 and a second mark 122 on the side near the first liquid addition hole 108. The connecting component 105 is used to connect the barrel stopper 101 and the liquid addition funnel 102.

[0027] In use, firstly, rotate the barrel stopper 101 so that the first mark 121 is aligned with the vent hole 110. At this time, the vent hole 110 is connected to the float hole 107, and the first filling hole 108 is connected to the second filling hole 109. Then, insert the bottom of the barrel stopper 101 into the container opening to seal the container opening. Liquid is then added to the container through the filling funnel 102. The liquid enters the container through the first filling hole 108 and the second filling hole 109, while the air inside the container is discharged through the float hole 107 and the vent hole 110. When the container is full, the buoyancy of the liquid causes the check valve 103 to float up and close the vent hole 110. At this time, liquid cannot enter the container, and the filling funnel 102 will accumulate liquid, thus clearly indicating that the container is full. After liquid accumulates in the container, stop adding liquid. Then, rotate the filling funnel 102 and the container stopper relative to each other by 120 degrees. Align the vent hole 110 on the filling funnel 102 with the second mark 122. At this time, the vent hole 110 is connected to the first filling hole 108, while the first filling hole 108 is offset from the second filling hole 109. Rotate the second filling hole 109 onto the sealing seat 104. At this time, the bottom of the second filling hole 109 is closed, facilitating the transfer of liquid from the filling funnel 102. Simultaneously, since the vent hole 110 is connected to the second filling hole 109, outside air can enter the container through the vent hole 110 and the second filling hole 109, preventing negative pressure inside the container from making the device difficult to remove. This avoids liquid overflow, waste, or splashing onto other items.

[0028] The cylinder mouth sealing ring 111 is connected to the cylinder mouth plug 101 and is sleeved on the cylinder mouth plug 101. The cylinder mouth plug 101 has an installation groove on its outer side that mates with the cylinder mouth sealing ring 111. The cylinder mouth sealing ring 111 is set in the installation groove, and multiple cylinder mouth sealing rings 111 are provided. The cylinder mouth sealing ring 111 is a fluororubber ring. The cylinder mouth sealing ring 111 seals the gap between the cylinder mouth plug 101 and the container mouth, preventing liquid from overflowing through the gap between the cylinder mouth plug 101 and the container mouth.

[0029] Secondly, the mounting nut 112 is rotatably connected to the barrel plug 101 and threadedly connected to the liquid adding funnel 102, and is fitted onto the barrel plug 101; the locking nut 113 is threadedly connected to the liquid adding funnel 102 and is fitted onto the liquid adding funnel 102; the liquid adding funnel 102 has external threads on its outer side, and the mounting nut 112 and the locking nut 113 have internal threads, and the mounting nut 112 has a screw-on anti-slip groove on its outer side; during installation, the mounting nut 112 is fitted onto the outer side of the barrel plug 101, and then the mounting nut 112 is threaded onto the outer side of the liquid adding funnel 102 and locked by the locking nut 113, thereby completing the assembly of this device. The entire installation and disassembly process is simple and easy to maintain.

[0030] Meanwhile, the upper sealing ring 114 is connected to the barrel plug 101 and contacts the liquid adding funnel 102; the lower sealing ring 115 is connected to the barrel plug 101 and contacts the mounting nut 112; both the upper sealing ring 114 and the lower sealing ring 115 are made of fluororubber rings. The upper sealing ring 114 seals the gap between the barrel plug 101 and the liquid adding funnel 102, and the lower sealing ring 115 seals the gap between the barrel plug 101 and the mounting nut 112, thereby improving the overall sealing performance of the device and preventing liquid leakage.

[0031] In addition, the buoyancy column 116 is movably disposed inside the float plug hole 107, and there is a gap between the buoyancy column 116 and the float plug hole 107; the sealing ball head 117 is fixedly connected to the buoyancy column 116 and is located on the side of the buoyancy column 116 near the vent hole 110; the diameter of the buoyancy column 116 is smaller than that of the float plug hole 107, so that air can flow through the float plug hole 107 and then be discharged through the vent hole 110. When the buoyancy column 116 rises under the action of liquid buoyancy, it drives the sealing ball head 117 to rise. When the sealing ball head 117 abuts against the bottom of the vent hole 110, the vent hole 110 is sealed.

[0032] Then, the limiting protrusion 118 is disposed inside the float plug hole 107 and limits the buoyancy column 116; multiple limiting protrusions 118 are disposed and evenly disposed inside the float plug hole 107. Through the limiting protrusion 118, the buoyancy column 116 can only move within the float plug hole 107, preventing the buoyancy column 116 from disengaging from the cylinder plug 101.

[0033] Finally, the positioning boss 119 is connected to the barrel plug 101 and located inside the mounting chamber 106; the sealing gasket 120 is connected to the positioning boss 119 and located on top of the positioning boss 119; the positioning boss 119 and the sealing gasket 120 are integrally formed, and the positioning boss 119 is embedded in the mounting chamber 106 on the barrel plug 101, which facilitates assembly. When the second liquid filling hole 109 is rotated above the sealing gasket 120, the bottom of the second liquid filling hole 109 is sealed by the sealing gasket 120, thereby facilitating the transfer of liquid inside the liquid filling funnel 102.

[0034] When using the liquid filling anti-overflow funnel of this utility model, first rotate the filling funnel 102 to align the vent hole 110 with the first mark 121. At this time, the vent hole 110 is connected to the float plug hole 107, and the second filling hole 109 is connected to the first filling hole 108. Then, insert the barrel plug 101 into the container barrel opening, and seal the gap between the barrel plug 101 and the container barrel opening with the barrel sealing ring 111. Then, through the filling funnel 102... 02. Liquid is added to the container. As liquid is continuously added, the air inside the container is discharged through the float hole 107 and the vent hole 110. When the liquid level rises to the buoyancy column 116, the buoyancy column 116 rises under the action of buoyancy, driving the sealing ball head 117 fixedly connected to it to rise together. When the sealing ball head 117 is in close contact with the bottom of the vent hole 110, the vent hole 110 is completely sealed. At this time, the liquid in the liquid addition funnel 102 will begin to... Liquid accumulates, forming a clear liquid surface to determine if the container is full. When liquid accumulation is observed in the filling funnel 102, liquid addition is stopped. The filling funnel 102 is then rotated 120 degrees relative to the barrel plug 101. During rotation, the second mark 122 on the barrel plug 101 is referenced to ensure that the vent hole 110 is finally aligned with the second mark 122, thereby aligning the vent hole 110 with the first filling hole 108. The second filling hole 109 rotates to above the sealing pad 120, which seals the second filling hole 109. Finally, the barrel plug 101 is pulled out, allowing outside air to smoothly enter the container through the vent hole 110 and the first filling hole 108, effectively balancing the air pressure inside and outside the container and avoiding difficulty in pulling out due to negative pressure. The liquid inside the filling funnel 102 can be easily transferred, thus preventing liquid overflow during the filling process.
