DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0024] Please refer to Figure 1 , Figure 2 and Figure 3, in this embodiment, a gas-water separator structure for a fuel cell is proposed, which includes a separation box 1. A plurality of guide plates 2 for bending and guiding are fixedly installed on the inner side wall of the separation box 1. The bottom ends of the plurality of guide plates 2 are communicated with a diversion plate 3 for guiding condensed water. A flow-through plate 31 for connection is fixedly installed between the diversion plates 3. One end of one of the diversion plates 3 is communicated with a first circulation plate 4 for transporting condensed water, and the other end of the other diversion plate 3 is communicated with a second circulation plate 5 for outputting condensed water. A circulation box 6 for circulating condensed water is communicated between the first circulation plate 4 and the second circulation plate 5. An overflow assembly 7 for discharging excess liquid is arranged at the top end of the circulation box 6. One side of the circulation box 6 is also communicated with a storage box 8 for storing separated liquid. A guiding assembly 9 for guiding liquid is arranged inside the storage box 8. The outer sides of the guide plates 2, the diversion plates 3, the flow-through plate 31, the first circulation plate 4, the second circulation plate 5, the circulation box 6 and the storage box 8 are all fixedly connected to the inner side wall of the separation box 1. A driving assembly 10 for circulating condensed water is arranged inside the separation box 1. When using this separator structure to separate gas and water, after inputting into the separation box 1, through the guiding action of the plurality of guide plates 2, after the gas-water contacts the low-temperature guide plates 2, the gas continues to move forward, while the liquid adheres to the guide plates 2 and flows downward. The precipitated liquid can be stored through the storage box 8, and the one-way assembly inside the storage box 8 can prevent the liquid inside the storage box 8 from flowing outwards. The liquid inside the storage box 8 can be transported to the inside of the circulation box 6 through the driving assembly 10. The driving assembly 10 continues to control the liquid inside the circulation box 6 to flow from the first circulation plate 4 into the end diversion plate 3, so as to continuously flow through the S shape formed by the diversion plate 3 and the flow-through plate 31. And because the diversion plate 3 is communicated with the guide plate 2, the guide plate 2 can be cooled by the condensed water, increasing the efficiency of gas-water separation. When the condensed water flows to the end diversion plate 3, the condensed water can be circulated into the second circulation plate 5 through the diversion plate 3, and the driving assembly 10 is used again to make the condensed water inside the second circulation plate 5 flow into the circulation box 6 for circulation. When the liquid inside the circulation box 6 continuously increases, when the liquid level height is higher than the overflow assembly 7, the excess liquid can be discharged outwards through the overflow assembly 7, thereby improving the gas-water separation effect of the overall separator structure;

[0025] Please refer to Figure 1 , Figure 4 and Figure 5, in this embodiment, a gas-liquid separator structure for a fuel cell is proposed. The overflow assembly 7 includes an overflow tank 71 connected to the top of the circulation tank 6. The outer side of the overflow tank 71 is fixedly connected to the inner side wall of the separation tank 1. The overflow assembly 7 further includes a drain pipe 72 connected to the outer side of the overflow tank 71, and the outer side of the drain pipe 72 is fixedly connected to the inner side wall of the separation tank 1. When the liquid level inside the circulation tank 6 is higher than that of the overflow tank 71, the liquid inside the circulation tank 6 can flow into the overflow tank 71, and then the excess liquid is discharged outward through the drain pipe 72 on the overflow tank 71. The driving assembly 10 includes a driving box 101 fixedly installed on one side inner wall of the separation tank 1. A driving rod 102 and three guide rotating rods 103 are respectively rotatably connected to the inner side wall of the driving box 101. The outer sides of the three guide rotating rods 103 are respectively rotatably connected to the inner side walls of the first circulation plate 4, the second circulation plate 5, and the circulation tank 6. The driving assembly 10 further includes linkage wheels 104 fixedly installed at the other end of the driving rod 102 and one end of the guide rotating rod 103. A belt 105 is sleeved on the outer side of the linkage wheel 104. Linkage gears 106 are fixedly installed at one end of one of the guide rotating rods 103 and the driving rod 102. The driving assembly 10 further includes a driving motor 107 fixedly installed on the inner side wall of the driving box 101. The output end of the driving motor 107 is fixedly connected to one end of the driving rod 102. The driving motor 107 drives the driving rod 102 inside the driving box 101. The driving rod 102 can drive one of the guide rotating rods 103 connected thereto to rotate through the action of the linkage gear 106. This guide rotating rod 103 rotates inside the storage tank 8, thereby increasing the inflow of the liquid accumulated on the top of the storage tank 8 into it and then into the circulation tank 6. Also, through the action of the linkage wheels 104 and the belt 105, the guide rotating rods 103 inside the first circulation plate 4 and the second circulation plate 5 can be driven to rotate in opposite directions relatively, causing the liquid inside the circulation tank 6 to flow into the first circulation plate 4 and the liquid inside the second circulation plate 5 to flow into the circulation tank 6 to form a circulation. The guiding assembly 9 includes a one-way valve 91 fixedly installed on the top inner wall of the storage tank 8. A filter grille 92 is fixedly installed on the top of the storage tank 8. When the liquid accumulated on the top of the storage tank 8 flows into the storage tank 8 for storage, the one-way valve 91 can prevent the internal liquid from overflowing upward. The other end of the separation tank 1 is also connected to an input pipe 11 for input. The input pipe 11 can be used to input into the separation tank 1. An exhaust pipe 12 is also connected to the outer side of the separation tank 1. The separated gas can be discharged outward through the exhaust pipe 12.

[0026] In this embodiment, during use, first, a plurality of guide plates 2 provided inside the separation box 1 can separate the gas and water input through the input pipe 11. The liquid after gas-water separation can be stored inside the storage box 8 by the rotation of the guide rotation rod 103 inside the storage box 8. At the same time, the liquid inside the storage box 8 is conveyed to the inside of the circulation box 6 through the guide rotation rod 103 inside it, so that the liquid inside the circulation box 6 can relatively rotate in the opposite direction through the guide rotation rod 103 inside the first circulation plate 4 and the second circulation plate 5, and the condensed water is input from the first circulation plate 4 into the plurality of guide plates 2 to cool the guide plates 2, and then the condensed water is circulated back to the inside of the circulation box 6 through the guide rotation rod 103 inside the second circulation plate 5. When the liquid level inside the circulation box 6 is higher than the overflow box 71, it can be discharged outward through the drain pipe 72, which improves the effect of the overall separator structure during the gas-water separation process and the convenience of equipment operation.

[0027] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
