[0040] As Figures 1 to 7As shown, the embodiment provides a water filling opening device, which comprises a filling main body 100, a cover plate 200 and a rotating shaft 300; the filling main body 100 comprises a side wall 110, a filter screen 120 and a glue dispensing ring 180, the side wall 110 is provided with a filling hole 111 along the vertical direction, the top end of the side wall 110 is provided with the glue dispensing ring 180, and the filter screen 120 is fixedly installed at the bottom end of the side wall 110 and located in the filling hole 111; the cover plate 200 can rotate relative to the filling main body 100 between an open position and a closed position, when the cover plate 200 is located at the closed position, the cover plate 200 closes the filling hole 111, when the cover plate 200 is located at the open position, the cover plate 200 opens the filling hole 111, and the glue dispensing ring 180 is elastically clamped between the side wall 110 and the cover plate 200; the rotating shaft 300 is used to drive the cover plate 200, the rotating shaft 300 is fixedly connected to the cover plate 200, the rotating shaft 300 penetrates through the filling main body 100 and is rotatably connected to the filling main body 100 around the axis of the rotating shaft 300, the axis of the rotating shaft 300 extends along the vertical direction, the rotating shaft 300 is in a stepped shape and has oppositely arranged first and second stepped surfaces 301 and 302, the first stepped surface 301 is in close contact with the lower surface of the cover plate 200, and the second stepped surface 302 is in close contact with the filling main body 100.

[0041] The water filling opening device fills the gap between the side wall 110 and the cover plate 200 by setting the glue dispensing ring 180 elastically clamped between the side wall 110 and the cover plate 200, so as to ensure that the gap can be effectively sealed when the cover plate 200 closes the glue dispensing ring 180. At the same time, the elastic design of the glue dispensing ring 180 ensures the reliability of its use and the sealing performance when closed, thereby realizing the structural improvement of the sealing structure of the water filling opening. The stepped structure design of the rotating shaft 300 makes the cooperation between the rotating shaft 300 and the filling main body 100 and the cover plate 200 more closely, reduces the friction and wear during rotation, enhances the structural stability, and prolongs the service life. The first stepped surface 301 is in close contact with the lower surface of the cover plate 200, and the second stepped surface 302 is in close contact with the filling main body 100. The above improvement of the sealing structure at the rotating shaft 300 helps to improve the sealing performance at the rotating shaft 300, ensures the stability during rotation, improves the overall sealing effect, and enhances the dustproof and waterproof ability. The above design is reasonable, stable in structure, easy to operate, has good sealing performance and reliability.

[0042] The cover plate 200 can be used to open and close the filling hole 111. The cover plate 200 is rotated between the open position and the closed position by the rotating shaft 300, so that the operation is convenient, thereby facilitating the filling operation of the filling hole 111, and preventing dust or foreign matter from entering the filling hole 111 when not in use, ensuring the cleanliness and safety of the filling hole 111. At the same time, the existence of the filter screen 120 can prevent impurities from entering from the filling hole 111.

[0043] In the embodiment, when the cover plate 200 is in the open position, the cover plate 200 is partially supported on the dispensing ring 180, thereby providing partial support for the cover plate 200, effectively inhibiting deformation of the cover plate 200 due to its own weight, thereby ensuring smooth operation of the water filling port device, reducing the risk of the cover plate 200 being stuck relative to the filling main body 100 position, and avoiding the cover plate 200 and the dispensing ring 180 from being worn out. Specifically, the dispensing ring 180 is made of flexible material. The above limitation allows the dispensing ring 180 to simultaneously function as a guide, noise eliminator, and seal.

[0052] The second ear plate 140 enhances the structural strength of the filling body 100, and provides a connection point between the rotating shaft 300 and the filling body 100. The second shaft sleeve 660 is coaxially sleeved on the rotating shaft 300, penetrates through the second ear plate 140 and is rotationally matched with the second ear plate 140, thereby providing additional support and rotation structure for the bottom end of the rotating shaft 300, making the rotation operation more stable and smooth, thereby enhancing the flexibility and stability of the water filling device.

[0054] The design of the transmission member 400 and the driving member 500 makes the operation of the water filling device more automatic and convenient. The transmission member 400 connects the driving member 500 and the rotating shaft 300, and through the driving of the driving member 500, the transmission member 400 stably transmits the driving force of the driving member 500 to the rotating shaft 300, drives the rotating shaft 300 to rotate, thereby controlling the opening and closing of the cover plate 200, thereby realizing the indirect driving of the driving member 500 to the rotating shaft 300, and reducing the direct acting force to the rotating shaft 300. The above design reduces the complexity of manual operation and improves the work efficiency.

[0055] Further, the transmission member 400 comprises a first swing rod 410 and a second swing rod 420, the second shaft sleeve 660 is clamped between the first end of the first swing rod 410 and the first end of the second swing rod 420 in the axial direction of the rotating shaft 300; the opposite second end of the first swing rod 410 is pivotally connected to the driving member 500, and the opposite second end of the second swing rod 420 is pivotally connected to the driving member 500; the water filling device further comprises a second gasket 670 and a second locking bolt 680, the rotating shaft 300 is stepped and has a third stepped surface 303, the side of the first swing rod 410 away from the second shaft sleeve 660 abuts against the third stepped surface 303, the second gasket 670 abuts against the side of the second swing rod 420 away from the second shaft sleeve 660, the second locking bolt 680 penetrates through the second gasket 670 and is fixedly connected to the bottom end of the rotating shaft 300, and the rotating shaft 300 and the second gasket 670 are spaced apart.
