[0030] like Figures 1-6 As shown, the liquid filling device with an anti-overflow structure provided in this embodiment includes: a deformable and recoverable bottle body 1, an electrolyte being filled in the bottle body 1, a bottle cap 102 being provided on the top of the bottle body 1, a filling tube 103 being connected to the bottle cap 102, a filling head 104 being connected to the other end of the filling tube, and both the filling head 104 and the filling tube 103 being connected to the bottle body 1; an auxiliary component 2 with a groove structure is provided between the filling tube 103 and the filling head 104.
[0031] The bottle body 1 can deform after an external force is applied and can return to its original position after the external force is removed. Specifically, the bottle body 1 can be flattened, and it can automatically return to its original position after being released.
[0032] Furthermore, the bottle cap 102 is threadedly connected to the top of the bottle body 1. The filling tube 103 is a flexible tube. The bottle body 1 is made of rubber. In other embodiments of this utility model, the bottle body 1 may be made of other deformable materials such as silicone. This utility model does not specifically limit the material of the bottle body 1.
[0033] During operation, the filling head 104 is inserted into the electrolyte filling port on the battery, the bottle body 1 is inverted, and it is slowly squeezed. When the bottle body 1 is slowly squeezed, the electrolyte inside the bottle body 1 is slowly added into the battery. During the filling process, if too much electrolyte is added, the electrolyte will enter the groove structure of the auxiliary component 2. The bottle body 1 is slowly released, and the rebound force of the bottle body 1 can draw the excess electrolyte into the bottle body 1, which can prevent the electrolyte from overflowing.
[0034] Furthermore, the auxiliary component 2 includes a sealing head 201 with a cavity, which can be sleeved on the filling head 104. When the filling head 104 is inserted into the electrolyte filling port on the battery, the sealing head 201 can contact the filling port on the battery to ensure that the edge of the filling port on the battery is sealed.
[0035] Further, the sealing head 201 is provided with a groove 202 on the side end face of the filling pipe 103, and the inner side of the sealing head 201 is provided with a discharge groove 203 in the axial direction.
[0036] Specifically, the sealing head 201 is made of rubber material; and the end of the filling head 104 is a tapered structure, so that it is more smooth and convenient when the filling head 104 is inserted into the filling port of the battery.
[0037] Further, the groove 202 is a tapered groove structure, which can avoid the electrolyte from remaining in the groove 202 when the liquid flows back in the groove 202; the number of the discharge grooves 203 is two, which are uniformly distributed in the radial direction of the sealing head 201, and each of the discharge grooves 203 is a semi-cylindrical groove structure.
[0038] Further, the bottle cap 102 is provided with an exhaust pipe 105, which is communicated with the bottle body 1. The exhaust pipe 105 is provided with a valve 106 for sealing the exhaust pipe 105, and the lower end of the exhaust pipe 105 is higher than the liquid level in the bottle body 1. When the bottle body 1 is squeezed and then slowly released in the inverted state, if the excess electrolyte cannot be completely sucked out after completely releasing, the bottle body 1 can be turned to the right position, the valve 106 is released and the bottle body 1 is squeezed, the gas in the bottle body 1 is discharged through the exhaust pipe 105, after the gas in the bottle body 1 is discharged, the valve 106 is tightened, the bottle body 1 is turned until the bottle cap 102 is downward, the bottle body 1 is released, and the excess electrolyte can be sucked out through the reset of the bottle body 1. Therefore, through the setting of the exhaust pipe 105 and the valve 106, when the bottle body 1 is completely released and the excess electrolyte cannot be completely sucked out, the bottle body 1 is turned to the right position, the valve 106 is released and the bottle body 1 is squeezed, the gas in the bottle body 1 is discharged through the exhaust pipe, which has high practicability.
[0039] Further, the outer wall of the bottle body 1 is provided with a plurality of protrusions 101 in the axial direction, and each of the protrusions 101 is arranged in a ring array. Specifically, the protrusion 101 is a semi-cylindrical structure, and the protrusion 101 is made of rubber material. The plurality of protrusions 101 collectively constitute a protective piece of the bottle body 1, which can prevent the bottle body 1 from being worn and scratched, and avoid the phenomenon of liquid leakage caused by wear and tear, so that the safety is higher.
[0040] The liquid adding device with the anti-overflow structure provided by the embodiment of the utility model can suck the excessive electrolyte into the bottle body through the rebound force of the bottle body when the electrolyte is added too much during the adding process, and the excessive electrolyte can be sucked out through the deformation and reset of the bottle body, so that the electrolyte added too much can be prevented from flowing out from the battery to the surface of the battery during the liquid adding process, and the problem of increasing the subsequent cleaning difficulty and damaging the battery shell is avoided.
[0041] Thus, the embodiments of the present disclosure have been described in detail. In order to avoid obscuring the concept of the present disclosure, some details known in the art are not described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein according to the above description.
[0042] Although some specific embodiments of the present disclosure have been described in detail through examples, those skilled in the art should understand that the above examples are only for illustration, not for limiting the scope of the present disclosure. Those skilled in the art should understand that the above embodiments can be modified or some technical features can be replaced equivalently without departing from the scope and spirit of the present disclosure.
