[0030] like Figure 1-8 As shown, the utility model provides a technical solution:

[0031] A hand-operated portable outdoor water purifier structure includes a filter tube module 1, which includes a filter tube body 4. A bottle interface 5 is provided in the middle of the bottom end of the filter tube body 4. A through hole 6 is provided on the side of the filter tube body 4 near the bottle interface 5.

A spring 9 is provided between the adjusting nut 8 and the regulating valve core 7. A water outlet 10 is provided in the middle of the regulating valve core 7.

[0032] like Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, the interior of the filter element tube module 1 is provided with a filter element module 2, and the filter element module 2 includes a membrane filter element body 11, and the membrane filter element body 11 is movably connected to the interior of the filter element tube body 4. A water outlet 12 is provided at the bottom end of the membrane filter element body 11, and a sealing ring 2 13 is provided between the water outlet 12 and the membrane filter element body 11. The bottom end of the water outlet 12 is movably connected to the middle part of the bottom end of the filter element tube body 4, and a sealing ring 3 14 is provided between the water outlet 12 and the bottom end of the filter element tube body 4. A sealing ring 16 is provided on the outside of the upper end of the membrane filter element body 11 through a sealing tape 15;

[0033] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the upper end of the filter tube module 1 is provided with a filter head module 3, and the filter head module 3 includes a filter head body 17. The filter head body 17 is threadedly sleeved with the top end of the filter tube body 4. A sealing ring 18 is provided between the filter head body 17 and the upper end of the filter tube body 4. The inner wall of the filter head body 17 is movably connected with the sealing ring 16. The filter head module 3 also includes a cavity 19 and a cavity 20. Cavity 19 and cavity 20 are respectively arranged inside the two sides of the filter head body 17. A valve plate 1 21 and a valve plate 2 22 are movably installed below the interior of cavity 19. The valve plate 1 21 is in opposite directions to the valve plate 2 22. A valve plate 3 23 and a valve plate 4 24 are movably installed below the interior of cavity 20. The valve plate 3 23 and the valve plate 4 24 are in opposite directions. One side of the filter head body 17 is connected with a water inlet 30.

[0034] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, a handle module 31 is provided between the filter head module 3 and the outside of the filter tube module 1, and the handle module 31 includes a handle body 25, which is provided between the filter head body 17 and the outside of the filter tube body 4. The top two ends of the handle body 25 are respectively movably installed with a piston 1 26 and a piston 2 27 through a hinge. The piston 1 26 is movably connected to the cavity 19, and the piston 2 27 is movably connected to the cavity 2 20. Two sealing rings 4 28 are provided on the outside of the piston 1 26 and the piston 2 27 from top to bottom. An anti-collision pad 29 is provided on the side of the handle body 25 close to the filter tube body 4. The end of the anti-collision pad 29 abuts against the upper outer wall of the filter tube body 4, and the top of the handle body 25 is movably connected to the top of the filter head body 17 through a rotating shaft.

[0035] In this embodiment, the device is modularly designed to facilitate production, assembly and inspection. Since the length of the filter head body 17 is relatively short, it avoids the problem of being too long and being unfavorable for the assembly of the internal valve plate assembly.

[0036] One end of the sealing ring 16 on the membrane filter element body 11 is fixed and sealed with a sealing tape 15, and the other end is free to move. Due to the thin-walled structure of the sealing ring 16, when the free movable end is under pressure, it can shrink inwards, and at the same time, the outer diameter expands outwards. When the pressure on the free movable end disappears, the free movable end will return to its original state. Therefore, when the water inlet end of the membrane filter element body 11 is under pressure, the pressure is transmitted to the sealing ring 16. The free movable end of the sealing ring 16 shrinks under the pressure, and at the same time, the outer diameter expands outwards, so that an effective seal is achieved between the membrane filter element body 11 and the filter element tube body 4. The higher the pressure, the better. The higher the diameter, the better the sealing effect. The structural advantage of the sealing ring 16 over the O-ring is that it has a certain compensating effect on cylindrical seals with low roundness, thereby reducing the processing requirements for roundness and reducing production costs. In addition, due to the characteristics of the free end that shrinks and expands outwards, the greater the pressure, the more obvious the outward expansion effect and the better the sealing effect. Secondly, due to the characteristics of the free end that shrinks and expands outwards, when the membrane filter element body 11 is installed into the filter element tube body 4, no excessive compression pre-tightening force is required, so the filter element module 2 can be installed and removed without using excessive force, which facilitates the assembly and replacement of the filter element module 2.

[0037] The bottom of the filter tube body 4 is provided with a bottle interface 5, which is an internal thread structure. The thread structure can be matched with a water storage container with a threaded head. When producing purified water, the water storage container can be used for collection, which is convenient for collecting purified water;

[0038] The mating surface between the regulating valve core 7 and the filter tube body 4 is a conical surface. The gap between the conical surfaces can be precisely adjusted by the adjusting nut 8. At the same time, as the pressure of the concentrated water outlet end below the membrane filter body 11 changes, the regulating valve core 7 is controlled to move up and down in the through hole 6. This can prevent the through hole 6 from being blocked by scaling or other impurities. Therefore, the regulating valve core 7 has the functions of precise adjustment and anti-blocking, which can extend the service life of the water purifier and user experience.

[0039] An anti-collision pad 29 is provided on the handle body 25 to prevent the outer surface of the filter tube body 4 from being damaged when the handle is shaken during use of the water purifier, while reducing the sound of the handle body 25 hitting the filter tube body 4, thereby improving user experience.

[0040] Working principle: The handle filter tube body 4 is pulled outward, the piston 27 moves upward, the volume of the cavity 20 increases, the valve disc 3 23 opens, the valve disc 4 24 closes, and the raw water is sucked into the cavity 2 20 through the water inlet 30. The handle body 25 is pressed inward again, the piston 1 26 moves upward, the volume of the cavity 19 increases, the valve disc 1 21 opens, the valve disc 2 22 closes, and the raw water is sucked into the cavity 19 through the water inlet 30; at the same time, the piston 27 moves downward, the volume of the cavity 20 decreases, the valve disc 4 24 opens, the valve disc 3 23 closes, and the raw water in the cavity 2 20 is pressed into the bottom of the filter head body 17, and then filtered by the membrane filter body 11, and the purified water comes out from the outlet. The water nozzle 12 is discharged and the concentrated water is discharged from the water outlet 10; when the handle body 25 is pulled outward again, the piston 2 27 moves upward, the valve plate 3 23 opens, the valve plate 4 24 closes, the volume of the cavity 20 increases, and the raw water is sucked into the cavity 2 20 through the water inlet 30. At the same time, the piston 1 26 moves downward, the volume of the cavity 19 decreases, the valve plate 2 22 opens, the valve plate 1 21 closes, and the raw water in the cavity 19 is pressed into the bottom of the filter head body 17, and then through the filtering effect of the membrane filter body 11, the clean water is discharged from the water outlet 12 and the concentrated water is discharged from the water outlet 10; this cycle repeats itself, the raw water is continuously sucked in, and the clean water and concentrated water are continuously discharged.
