DETAILED DESCRIPTION

[0023] The present technology will be further explained in detail in combination with the drawings and specific embodiments.

[0026] The embodiment discloses a press-starting type emergency drinking positive osmosis water bag, and the overall structure is shown in

[0027] Based on the characteristics of the plastic material, the outer supporting bag 1 is heat-pressed to form a main body heat-pressing closed edge 2 at the four positions, so that the inner part of the outer supporting bag 1 forms a closed space through the main body heat-pressing closed edge 2, and the water leakage during the water taking process of the product can be ensured.

[0033] The embodiment discloses a press-starting type emergency drinking positive osmosis water bag, and the overall structure is shown in

[0034] In addition, in order to facilitate the disassembly of the external supporting bag 1, a tearable notch 6 is arranged at any one corner position of the external supporting bag 1, and one side of the tearable notch 6 is provided with a tear notch indicating line 7 for prompting.

[0035] Embodiment two

[0036] The embodiment discloses a press-starting soft package emergency drinking positive osmosis water bag, and is different from the structure disclosed in embodiment one in that the setting of the drawing inner bag 5.

[0037] In the embodiment, the drawing substance is drawing liquid, and the drawing liquid is a solution of one or more of monosaccharide, polysaccharide or electrolyte powder, and has the characteristic of being edible.

[0038] In order to realize the performance of the pressable release of the drawing substance of the drawing inner bag 5, as shown in the figure, a pre-folding pressure mark 52 is arranged on the side of the bag body of the drawing inner bag 5. Figure 3 Due to the thinning of the drawing liquid bag 5 at the pre-folding pressure mark 8, the pre-folding mark of the drawing liquid bag can be broken through the extrusion mode, so that the drawing liquid enters the water bag, the drawing liquid contacts the positive osmosis membrane in the external supporting bag 1, and forms a high-concentration liquid environment, which cooperates with the characteristics of the positive osmosis membrane 3, so that the water in the external environment can enter the water bag through the positive osmosis membrane 3, to realize the emergency water taking use requirement of the emergency drinking positive osmosis water bag.

[0039] Embodiment three

[0040] The embodiment discloses a press-starting soft package emergency drinking positive osmosis water bag, and is different from the structure disclosed in embodiment one in that the setting of the drawing inner bag 5.

[0041] In the embodiment, the drawing substance is drawing liquid, and the drawing liquid is a solution of one or more of monosaccharide, polysaccharide or electrolyte powder, and has the characteristic of being edible.

[0042] In order to realize the performance of the pressable release of the drawing substance of the drawing inner bag 5, as shown in the figure, a pre-folding pressure mark 52 is arranged on the side of the bag body of the drawing inner bag 5. Figure 4 The one-way pressure valve 53 is made of soft material, for example, soft silica gel; a release port is arranged on the pressure valve body, when the drawing inner bag 5 is extruded, the drawing liquid will open the release port, so that the drawing liquid is released. In the case that no extrusion force is applied, the one-way pressure valve 53 is made of soft material, and can restore the original shape to close the release port.

[0043] Therefore, for the press-activated emergency drinking forward osmosis water bag disclosed in this embodiment, the release port of the one-way pressure valve 53 can be opened by applying force and squeezing, so that the extractable liquid enters the water bag. The extractable liquid contacts the forward osmosis membrane 3 in the outer support bag 1 and forms a high-concentration liquid environment. In combination with the characteristics of the forward osmosis membrane 3, water from the external environment can enter the water bag through the forward osmosis membrane 3 to meet the emergency water intake needs of this emergency drinking forward osmosis water bag.

[0044] Example 4

[0045] This embodiment discloses a press-activated soft-pack emergency drinking forward osmosis water bag. Based on the structure disclosed in Embodiment 1, the difference lies in that the inner draw-out bag 5 contains a draw-out solid. The draw-out solid is one or more powders of monosaccharides, polysaccharides, or electrolyte powders, and is edible.

[0046] To achieve the press-release function of the inner bag 5 for extracting substances, such as Figure 2 As shown, a thin region 51 that can be pressed and squeezed is provided at any position of the inner bag 5. The thin region 51 is formed by stretching the inner bag 5. Since it is thinner than the inner bag 5, the thin region 51 will break first when the inner bag 5 is squeezed.

[0047] Since the material encapsulated in the inner drawer bag 5 is a powdered solid, it is pre-filled with inert gas to allow the drawer solid to be ejected. On the one hand, a full inner drawer bag 5 is easy to press and break; on the other hand, the gas-solid mixture of powdered solid can be ejected to enter the outer support bag 1.

[0048] Therefore, for the press-activated emergency drinking forward osmosis water bag disclosed in this embodiment, it is shaken before use to disperse the absorbent solids. Then, by applying pressure, the thin area of ​​the inner absorbent bag 5 can be broken, allowing the absorbent solids to enter the outer support bag. The absorbent solids contact the forward osmosis membrane inside the outer support bag 1, forming a high-concentration environment. Combined with the characteristics of the forward osmosis membrane 3, water from the external environment can pass through the forward osmosis membrane 3 into the water bag, thereby meeting the emergency water intake needs of this emergency drinking forward osmosis water bag.

[0049] Therefore, based on the technical content disclosed in embodiments one to four, it is known that the actual use mode of the press-starting emergency drinking forward osmosis water bag disclosed in the present application is that when the product is actually used, pressure (usually greater than 15 kg) is applied to the extraction inner bag 5, so that the thin area 51 or the pre-disassembly pressure mark 52 of the extraction inner bag 5 is broken, or the one-way pressure valve 53 is opened, so that the extraction liquid or extraction solid enters the forward osmosis water bag to form a high concentration environment. Subsequently, the whole water bag is immersed in the natural water body to be filtered, and the process needs to be continued for 6-8 hours, during which pure water can enter the water bag through the forward osmosis membrane 3, and after the process is completed, the external supporting bag 1 can be disassembled using scissors or other sharp tools or by using the easy-to-tear notch 6, and the water can be drunk.

[0050] Compared with the prior art, the present application provides a new emergency drinking forward osmosis water bag, which is soft-packaged as a whole and has the characteristics of portability.

[0051] At the same time, the forward osmosis water bag is wrapped with an extraction inner bag that can be squeezed into the water bag. Before use, the sealing property of the extraction inner bag is used to avoid the extraction solid or extraction liquid from absorbing water and failing during storage. The extraction solid or extraction liquid is squeezed into the external supporting bag immediately when used, which has the advantages of high freshness and stability, to ensure high forward osmosis pressure and the freshness of the generated liquid, and to realize the demand for high safety of emergency drinking in outdoor environments. When used, the extraction material is released into the forward osmosis water bag by squeezing and releasing the extraction liquid bag, and then the whole water bag is immersed in the water body, which has the characteristics of simple operation and strong implementability.

[0052] The above embodiments are not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solutions of the present application also fall within the protection scope of the present application.
