[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] Please see Figure 1 - Figure 4 A single-person seawater desalination device includes a desalination device body 1, one end of which is provided with a fresh water connector 2 and a water inlet connector 3, and the water inlet connector 3 is located above the fresh water connector 2.

[0026] A valve body 4 is provided on the desalination unit body 1. A piston 16 is provided inside the valve body 4. A retaining seat 6 is installed on the valve body 4. A handle 7 is provided on one side of the retaining seat 6. A drive shaft 14 is fixedly installed on one side of the handle 7. The drive shaft 14 is rotatably installed on the retaining seat 6. A gear 15 is installed on the drive shaft 14. The gear 15 is meshed with the piston 16.

[0027] The desalination unit 1 is equipped with an RO membrane assembly 18 inside. One end of the RO membrane assembly 18 is equipped with a concentrate plug 19, and the other end of the concentrate plug 19 is equipped with a pressure spring 20.

[0028] One end of the RO membrane module 18 is provided with a freshwater connector 17, and the freshwater connector 2 is connected to the freshwater connector 17;

[0029] The desalination unit 1 has a rear cover 22 at its rear end, and a concentrate outlet 21 on the rear cover 22. A pressure relief pin 12 is inserted into the concentrate outlet 21.

[0030] The individual seawater desalination device provided by this utility model is used by manually pressing the handle 17 repeatedly, which drives the transmission shaft 14 and gear 15 to rotate. The rotating gear 15 then drives the piston 16, which is meshed with it, to reciprocate within the valve body 4, thereby generating pressure to force seawater into the RO membrane module 18. Then, freshwater flows out from the freshwater connector 2 through the freshwater connector 17 and enters the collection container or the user's mouth. The concentrated water is temporarily stored in the cavity after being regulated by the concentrated water plug 19 and the pressure spring 20. When it is necessary to discharge the concentrated water or when the system pressure is too high, the pressure relief pin 12 is pulled out, and the concentrated water is discharged from the concentrated water port 21. After discharge, the pressure relief pin 12 can be reinserted to continue the desalination operation. Finally, the back cover 22 is unscrewed to remove the RO membrane module 18 for cleaning or replacement.

[0031] Furthermore, a one-way valve is provided between the water inlet connector 3 and the valve body 4. The one-way valve includes a one-way valve core 24 and a one-way valve seat 25.

[0032] Specifically, the cooperation between the one-way valve seat 25 and the one-way valve core 24 forms a sealing surface, preventing reverse flow.

[0033] Furthermore, a water-stop spring 23 is provided between the one-way valve core 24 and the one-way valve seat 25.

[0034] Specifically, the water-stop spring 23 provides a preload, which keeps the one-way valve core 24 closed when there is no positive pressure. At the same time, when the inlet water pressure exceeds the preload of the water-stop spring 23, the one-way valve core 24 opens, allowing seawater to enter.

[0035] Furthermore, a second handle 11 is provided on the outer side of the first handle 7. A pivot pin 9 is provided on the second handle 11, and the second handle 11 is connected to the first handle 7 through the pivot pin 9. A pull pin 10 is inserted into the hole connecting the first handle 7 and the second handle 11.

[0036] Specifically, the pivot pin 9 allows the handle 11 connected to the handle 7 to be rotated and unfolded, and then fixed by the pull pin 10, thereby increasing the lever arm length of the handle 7 and making the pressing operation easier.

[0037] Furthermore, the valve body 4 is provided with screws 5, and the valve body 4 is fixedly connected to the desalination unit body 1 by the screws 5.

[0038] Specifically, when disassembling the valve body 4, screws 5 can be unscrewed to separate the retaining seat 6 and related transmission components, making it easier to maintain moving parts such as pistons and gears.

[0039] Furthermore, the desalination unit body 1 is provided with a plug 13, and the retaining seat 6 is provided with a plug 8.

[0040] Specifically, the plug 13 is used to seal the process holes or spare interfaces on the desalination unit body 1 to ensure the sealing and structural integrity of the shell, while the plug 8 is used to seal the end of the retaining seat 6 to prevent external impurities from entering the transmission area of ​​the gear 15 and piston 16, ensuring smooth transmission and service life.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
