At this time, the liquid adding funnel 102 is rotated to drive the exhaust hole 110 and the second liquid adding hole 109 to rotate, so that the exhaust hole 110 is connected with the first liquid adding hole 108 to avoid the negative pressure in the container causing the barrel plug 101 to be difficult to pull out. At the same time, the second liquid adding hole 109 is rotated to the top of the sealing seat 104 to avoid the liquid in the liquid adding funnel 102 from flowing out, which is convenient for transferring liquid. It can be understood that the above scheme can be used to avoid liquid overflow when adding liquid to the container, and can also be used to improve the sealing effect between the barrel plug 101 and the container.

[0026] According to the present specific embodiment, the liquid adding funnel 102 is rotatably connected to the barrel mouth plug 101 and is arranged on the barrel mouth plug 101. The barrel mouth plug 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 mouth plug 101 close to the liquid adding funnel 102.

The sealing seat 104 is connected to the barrel mouth plug 101 and is located on the barrel mouth plug 101 close to the installation chamber. On one side of the barrel mouth plug 106, the connecting component 105 is arranged on the barrel mouth plug 101, and connects the barrel mouth plug 101 and the liquid adding funnel 102, the liquid adding funnel 102 has a second liquid adding hole 109 and an exhaust hole 110, the second liquid adding hole 109 runs through the liquid adding funnel 102, and is communicated with the first liquid adding hole 108, the exhaust hole 110 runs through the liquid adding funnel 102, and is communicated with the float hole 107; the barrel mouth plug 101 is provided with a first mark 121 on the side close to the check float 103, and is provided with a second mark 122 on the side close to the first liquid adding hole 108, and the connecting component 105 is used to connect the barrel mouth plug 101 and the liquid adding funnel 102.

[0027] When in use, first rotate the barrel plug 101 to rotate the first mark 121 to align with the exhaust hole 110, at which time the exhaust hole 110 is connected to the float hole 107, and the first liquid adding hole 108 is connected to the second liquid adding hole 109; then extend the bottom of the barrel plug 101 into the barrel mouth of the container so that the barrel plug 101 seals the barrel mouth of the container, and add liquid to the container through the liquid adding funnel 102. The liquid enters the container through the first liquid adding hole 108 and the second liquid adding hole 109, and the air inside the container is discharged through the float hole 107 and the exhaust hole 110; when the liquid is full, the buoyancy of the liquid causes the check float 103 to float up and close the exhaust hole 110. At this time, the liquid cannot enter the container, and the liquid adding funnel 102 will accumulate liquid, so that it is clear that it is full; the liquid adding funnel 10 2, stop adding liquid, then rotate the liquid adding funnel 102 and the barrel mouth plug relatively, so that they rotate 120 degrees, so that the exhaust hole 110 on the liquid adding funnel 102 is aligned with the second mark 122, at this time, the exhaust hole 110 is connected with the first liquid adding hole 108, and the first liquid adding hole 108 is staggered with the second liquid adding hole 109, so that the second liquid adding hole 109 is rotated to the sealing seat 104, and the bottom of the second liquid adding hole 109 is closed at this time, which is convenient for transferring the liquid in the liquid adding funnel 102; at the same time, because the exhaust hole 110 is connected with the second liquid adding hole 109 at this time, the outside air can enter the container through the exhaust hole 110 and the second liquid adding hole 109, so as to avoid the negative pressure in the container causing the device to be difficult to pull out, thereby avoiding the problem of liquid overflow, resulting in waste or splashing onto other items.

[0028] Among them, the barrel mouth sealing ring 111 is connected to the barrel mouth plug 101 and is sleeved on the barrel mouth plug 101; the outer side of the barrel mouth plug 101 is provided with a mounting groove that cooperates with the barrel mouth sealing ring 111, the barrel mouth sealing ring 111 is arranged in the mounting groove, and there are multiple barrel mouth sealing rings 111, the barrel mouth sealing ring 111 is a fluororubber ring, and the barrel mouth sealing ring 111 is used to seal the gap between the barrel mouth plug 101 and the barrel mouth of the container to prevent liquid from overflowing through the gap between the barrel mouth plug 101 and the barrel mouth of the container.

[0029] Secondly, the mounting nut 112 is rotatably connected to the barrel mouth plug 101, and is threadedly connected to the liquid adding funnel 102, and is sleeved on the barrel mouth plug 101; the locking nut 113 is threadedly connected to the liquid adding funnel 102, and is sleeved on the liquid adding funnel 102; the outer side of the liquid adding funnel 102 is provided with an external thread, and the mounting nut 112 and the locking nut 113 are provided with internal threads, and the outer side of the mounting nut 112 is provided with a screwing anti-skid groove; during installation, the mounting nut 112 is sleeved on the outer side of the barrel mouth plug 101, and then the mounting nut 112 is threadedly connected to the outer side of the liquid adding funnel 102, and is locked by the locking nut 113, thereby completing the assembly of the device, and the entire installation and disassembly process is simple and easy to maintain.

[0030] At the same time, the upper sealing ring 114 is connected to the barrel mouth plug 101 and contacts the liquid adding funnel 102; the lower sealing ring 115 is connected to the barrel mouth plug 101 and contacts the mounting nut 112; the upper sealing ring 114 and the lower sealing ring 115 are both made of fluororubber rings, and the gap between the barrel mouth plug 101 and the liquid adding funnel 102 is sealed by the upper sealing ring 114, and the gap between the barrel mouth plug 101 and the mounting nut 112 is sealed by the lower sealing ring 115, thereby improving the overall sealing performance of the device and avoiding liquid leakage.

[0031] In addition, the buoyancy column 116 is movably arranged 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 close to the exhaust hole 110; the diameter of the buoyancy column 116 is smaller than the float plug hole 107, so that air can flow through the float plug hole 107 and then be discharged through the exhaust hole 110. When the buoyancy column 116 rises under the action of the buoyancy of the liquid, it drives the sealing ball head 117 to rise. When the sealing ball head 117 abuts against the bottom of the exhaust hole 110, the exhaust hole 110 is sealed.

[0032] Then, the limiting protrusion 118 is arranged on the inner side of the float hole 107, and limits the buoyancy column 116; there are multiple limiting protrusions 118, and they are evenly arranged on the inner side of the float hole 107. Through the limiting protrusion 118, the buoyancy column 116 can only move in the float hole 107, preventing the buoyancy column 116 from being separated from the barrel mouth plug 101.

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

[0034] When using the liquid filling anti-overflow funnel of the present invention, first rotate the liquid adding funnel 102 to align the exhaust hole 110 with the first mark 121. At this time, the exhaust hole 110 is connected to the float hole 107, and the second liquid adding hole 109 is connected to the first liquid adding hole 108. Then, the barrel mouth plug 101 is inserted into the barrel mouth of the container, and the gap between the barrel mouth plug 101 and the barrel mouth of the container is sealed by the barrel mouth sealing ring 111; then, liquid is added to the container through the liquid adding funnel 102. As the liquid is continuously added, the air inside the container is discharged through the float hole 107 and the exhaust 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 thereto to rise together. When the sealing ball head 117 is in close contact with the bottom of the exhaust hole 110, the exhaust hole 110 is completely sealed. At this time, the liquid in the liquid adding funnel 102 will begin to accumulate. The liquid surface is gathered to form an obvious liquid surface, so as to judge whether the liquid is full; when it is observed that there is liquid accumulation in the liquid adding funnel 102, stop adding liquid, and then rotate the liquid adding funnel 102 so that it rotates 120 degrees relative to the barrel mouth plug 101. During the rotation process, refer to the second mark 122 on the barrel mouth plug 101 to ensure that the exhaust hole 110 is finally aligned with the second mark 122, so that the exhaust hole 110 is aligned with the first liquid adding hole 108, and the second liquid adding hole 109 is rotated to above the blocking pad 120, and the second liquid adding hole 109 is sealed by the blocking pad 120; finally, the barrel mouth plug 101 is pulled out, and the outside air can smoothly enter the interior of the container through the exhaust hole 110 and the first liquid adding hole 108, thereby effectively balancing the air pressure inside and outside the container, avoiding the difficulty of pulling out due to negative pressure, and the liquid inside the liquid adding funnel 102 can be conveniently transferred, thereby solving the problem of liquid overflow during the process of adding liquid to the container.
