DETAILED DESCRIPTION

[0029] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0030] Embodiment 1:

[0031] like Figure 1-7As shown, the aluminum fuel cell liquid distribution bag provided by the utility model includes: a water bag 1, a threaded cup cover 2, a cup cover cap 3, a cup cover handle 4, a bag bottom handle 5 and a bottom bracket 6. The threaded cup cover 2 is threadedly connected to the bag opening 8 at the top of the water bag 1. The threaded cup cover 2 is eccentrically provided with a first liquid outlet 13. The cup cover cap 3 is buckled on the top of the threaded cup cover 2. The two ends of the cup cover handle 4 are respectively connected to the water bag 1 and the cup cover cap 3. The bag bottom handle 5 is connected to the bottom of the water bag 1. The bottom bracket 6 is installed at the bottom of the water bag 1. , the cup cover handle 4 and the bag bottom handle 5 are all made of plastic material, specifically modified TPU, the hardness of the water bag 1 and the bag bottom handle 5 is 40HD, the hardness of the threaded cup cover 2, the cup cover cap 3, the cup cover handle 4 and the bottom support 6 is 90HD, the thickness of the water bag 1 is 0.3-0.5mm, the thickness of the bottom support 6 is 1.5mm, and the bottom support 6 wraps the bottom of the water bag 1. When a 6-8mol / L alkaline solution is configured, potassium hydroxide or sodium hydroxide powder will release a lot of heat when it comes into contact with water, especially the alkaline powder precipitated at the bottom will release a lot of heat when it comes into contact with water. A high temperature point is formed at the bottom of the cup (temperature of the high temperature point is ≧120°C). Since the water bag 1 and the bottom bracket 6 form a thicker bottom, the bottom of the water bag 1 can be effectively prevented from being burned through. The thicker bottom bracket 6 is placed flat on the table, which increases the bottom support strength of the water bag 1 and the stability of the water bag 1, and can effectively prevent the water bag 1 from tipping over. When using, unscrew the threaded cup cover 2, prepare the solution in the water bag 1, and then screw on the threaded cup cover 2. When pouring the solution, first open the cup cover cap 3 to expose the first liquid outlet 13, and hold the cup cover handle 4 and the bag bottom handle 5 with both hands respectively. The height of the bag bottom handle 5 gradually exceeds the cup cover handle 4, so that the water bag 1 is tilted, and the solution in the water bag 1 is poured out from the first liquid outlet 13 and enters the battery. The cup cover handle 4 and the bag bottom handle 5 prevent the operator's limbs from directly contacting the high-temperature liquid preparation bag (mainly the water bag 1 part), thereby preventing the operator from being scalded by the high-temperature liquid preparation bag or squeezing the high-temperature electrolyte out of the liquid preparation bag due to operational errors, causing danger. When not in use, the water bag 1 itself can be compressed by exhausting air, so that the overall volume of the liquid preparation bag is reduced, making it more convenient to carry, store and transport.

[0032] By arranging the water bag 1, the threaded cup cover 2, the cup cover cap 3, the cup cover handle 4, the bag bottom handle 5 and the bottom support 6 made of modified TPU material, the alkali resistance is strong, and the alkaline liquid will not be penetrated when it is contained. The overall weight is small, the volume can be reduced, and it is more convenient to carry, store and transport.

The auxiliary support bars 7 are made of the same material as the water bag 1 and have a thickness of 0.2-0.3 mm. The auxiliary support bars 7 are distributed in a circular array, which can strengthen the vertical support strength of the water bag 1 and make the water bag 1 less likely to tip over when standing upright.

[0050] By installing auxiliary support bars 7 in a circular array on the side of the water bag 1, the side support of the water bag 1 can be strengthened.

[0051] Working principle: When in use, first open the cup cover cap 3 to expose the first liquid outlet 13, hold the cup cover handle 4 and the bag bottom handle 5 with both hands respectively, the height of the bag bottom handle 5 gradually exceeds the cup cover handle 4, so that the water bag 1 is tilted, and the solution in the water bag 1 is poured out from the first liquid outlet 13 and injected into the battery filling port. The cup cover handle 4 and the bag bottom handle 5 are used to prevent the operator's limbs from directly contacting the high-temperature liquid preparation bag, thereby preventing the operator from being scalded by the high-temperature liquid preparation bag or squeezing the high-temperature electrolyte out of the liquid preparation bag due to operating errors, causing danger. When not in use, the water bag 1 itself can compress the volume by exhausting air, so that the overall volume of the liquid preparation bag is reduced, which is more convenient to carry, store and transport.
