Description

Technical Field

[0001] This invention relates to a small, lightweight, filtered water bottle with a nested structure, belonging to the field of water bottle technology. Background Technology

[0002] As an indispensable piece of equipment for soldiers during marches, the marching canteen plays a vital role in national defense. When soldiers are on marches in the field, they experience significant dehydration due to prolonged periods of high-intensity activity and harsh outdoor environments. In such situations, they often need to find water sources along the marching route, but the quality of the water they obtain cannot be guaranteed. If these water sources are not effectively filtered, soldiers are highly likely to ingest various microorganisms that pose serious health risks, undoubtedly causing significant harm to their well-being.

[0003] Currently available marching water bottles typically achieve water purification by increasing their volume and adding an external pressurization device, allowing water from field sources to pass smoothly through filtration materials such as activated carbon and ultrafiltration membranes. However, this type of marching water bottle has a significant drawback: its relatively large size makes it very inconvenient to carry during field marches, increasing the burden on soldiers and making movement more difficult. If boiling water is used for disinfection, firstly, the resulting flames and smoke in the field could easily reveal the soldiers' location, posing unnecessary safety risks; secondly, a dedicated heating device would need to be carried, further increasing the equipment load and subjecting various limitations in practical operation.

[0004] In view of the above problems, in order to better meet the needs of soldiers for safe and convenient drinking water during field marches, it is essential to develop a new type of marching water bottle. This new marching water bottle should have the function of achieving efficient water filtration within a relatively small space, in order to overcome the shortcomings of existing marching water bottles and provide stronger equipment support for national defense. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a small and lightweight filter water bottle with a nested structure, which effectively solves the problem of the large size of the current pressurized filter water bottles, so that the water bottle can be more convenient to carry and use while having a high-efficiency filtration function.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: a small and lightweight filtered military water bottle with a nested structure, including an outer bottle body, a detachable inner bottle body connected to the inside of the outer bottle body, the spout of the inner bottle body facing downward and connected to a detachable filter cup, and the inner wall of the filter cup being provided with a spun internal thread. The outer pot body is connected to a detachable pot lid at the spout. A protruding column is fixedly installed on the pot lid. The outer periphery of the protruding column is provided with a spun external thread. The inner end face of the protruding column is a spun flat surface and abuts against the bottom of the outer pot body of the inner pot body.

[0007] Preferably, a filter assembly is provided on the inner bottom of the filter cup. The filter assembly includes a filter layer. Multiple support pads are fixedly connected between the inner end face of the filter layer and the inner bottom of the filter cup. A sieve plate fixed on the filter cup is provided on the outer end face of the filter layer. Several flow holes located on the peripheral cup wall of the filter cup are provided in the cavity between the inner end face of the filter layer and the inner bottom of the filter cup. A one-way valve is installed on each flow hole.

[0008] Preferably, an outwardly flared annular cup sleeve is fixed to the edge of the filter cup, and an annular groove for embedding the edge of the inner pot body is formed between the inner peripheral wall of the annular cup sleeve and the outer peripheral wall of the filter cup.

[0009] Preferably, the inner pot body has several notches evenly distributed around the circumference of the spout edge, and the annular groove has several protrusions fixed inside to correspond one-to-one with and be embedded in the notches.

[0010] Preferably, the bottom of the inner pot of the outer pot body is provided with an embedding groove for interlocking with the annular cup sleeve.

[0011] Preferably, a sealing ring is provided between the connecting end face of the embedded groove and the annular cup sleeve, and between the edge of the inner pot body and the connecting end face of the annular groove.

[0012] Preferably, the lid and the spout of the outer pot body are screwed together.

[0013] Preferably, a semi-circular groove that radially penetrates the lid is provided on the outer end face of the lid.

[0014] Compared with the prior art, the present invention has the following beneficial effects: When not in use, this small, lightweight, filtered water bottle with a nested structure has the filter cup fitted onto the spout of the inner bottle. The filter cup and the inner bottle are then stored inside the outer bottle, with the spout of the inner bottle facing down. After the lid is placed on the outer bottle, the spun flat surface of the lid's protruding column abuts against the bottom of the outer bottle, preventing the inner bottle from shaking and making it easy to carry.

[0015] To use, invert the canteen, unscrew the lid, and remove the inner canteen and filter cup. Place the filter cup onto the spout of the inner canteen. Use the outer canteen to draw water and pour it into the filter cup. The water will then flow into the inner canteen after being filtered. During filtration, the external and internal threads of the lid's protruding column can be screwed together. Rotating the lid lowers it, causing the screwed surface to pressurize the water in the filter cup, creating a pressurized filtration effect and effectively improving filtration efficiency. After filtration, the clean water from the inner canteen is ready to drink directly.

[0016] This technology uses the protruding column of the lid to pressurize, eliminating the need for a separate pressurization space. When not in use, the water bottle can be folded and stored, effectively reducing its size and making it easier to carry.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] like Figures 1-8 As shown, this embodiment provides a small, lightweight, filtered military water bottle with a nested structure, including an outer bottle body 1, and a detachable inner bottle body 2 connected to the inside of the outer bottle body. The spout of the inner bottle body faces downward and is connected to a detachable filter cup 3. The inner wall of the filter cup is provided with a spun internal thread 4. The outer pot body is connected to a detachable pot lid 5. A protruding column 6 is fixedly installed on the pot lid. The outer periphery of the protruding column is provided with a spun external thread 7. The inner end face of the protruding column is a spun flat surface and abuts against the bottom of the outer pot body of the inner pot body.

[0030] In this embodiment of the invention, a filter assembly is provided on the inner bottom of the filter cup. The filter assembly includes a filter layer 8. A plurality of support pads 9 are fixedly connected between the inner end face of the filter layer and the inner bottom of the filter cup. A sieve plate 10 fixed on the filter cup is provided on the outer end face of the filter layer. A plurality of flow holes 11 located on the peripheral cup wall of the filter cup are provided in the cavity between the inner end face of the filter layer and the inner bottom of the filter cup. A one-way valve 12 is installed on each flow hole.

[0031] In this embodiment of the invention, the filter layer is composed of a filter element consisting of activated carbon and an ultrafiltration membrane.

[0032] In this embodiment of the invention, an outwardly folded annular cup sleeve 13 is fixed on the edge of the filter cup, and an annular groove 14 for embedding the edge of the inner pot body is formed between the inner peripheral wall of the annular cup sleeve and the outer peripheral wall of the filter cup.

[0033] In this embodiment of the invention, the inner pot body has a number of notches 15 evenly distributed around the circumference of the spout edge, and the annular groove has a number of protrusions 16 fixed inside to correspond one-to-one with and be embedded in the notches.

[0034] In this embodiment of the invention, an inlay groove 17 is provided on the bottom of the inner pot of the outer pot body for interlocking with the annular cup sleeve. The inlay groove is used to prevent radial shaking of the filter cup / inner pot body during storage.

[0035] In this embodiment of the invention, a sealing ring 18 is provided between the connecting end face of the embedded groove and the annular cup sleeve, and between the edge of the inner pot body and the connecting end face of the annular groove.

[0036] In this embodiment of the invention, the lid and the mouth of the outer pot body are screwed together.

[0037] In this embodiment of the invention, a semi-circular groove 19 that radially penetrates the outer end face of the lid is provided.

[0038] In this embodiment of the invention, the working method of the small, lightweight, filtered water bottle with the inner-outer-outer-outer-structure is as follows: When not in use, the filter cup is fitted onto the spout of the inner pot, and then the filter cup and the inner pot are stored inside the outer pot with the spout of the inner pot facing down. After the lid is placed on the outer pot, the spun flat surface of the outer protruding column of the lid abuts against the bottom of the outer pot of the inner pot to prevent axial movement of the inner pot and reduce noise during marching.

[0039] When using, invert the canteen, unscrew the lid, and take out the inner canteen and filter cup. The filter cup is fitted onto the spout of the inner canteen. When fitting, the edge of the spout of the inner canteen is embedded in a ring-shaped groove, and the protrusions inside the ring-shaped groove are embedded into the notches one by one, so that the filter cup and the inner canteen cannot rotate relative to each other.

[0040] Water is drawn into the outer pot and poured into the filter cup in several portions. After being filtered, the water flows into the inner pot. During filtration, the external and internal threads of the outer protruding post on the lid can be screwed together. This allows the lid to be rotated and lowered, causing the spun surface to compress the water in the filter cup, creating a pressurized filtration effect. (For pressurization, a long rod can be inserted into the semi-circular groove nearby, using leverage to increase the rotational torque for enhanced filtration.) Under the pressure of the water above, the one-way valve opens, allowing the filtered clean water to flow through the flow hole into the inner pot, effectively improving filtration efficiency. The filtered water in the inner pot is then ready to drink.

[0041] After drinking, the filtered clean water in the inner pot can be stored. To do this, discard the dirty water from the outer pot and lightly wash the filter cup to remove any visible impurities. Then, place the filter cup onto the spout of the inner pot and invert the outer pot. Insert the inner pot, with its spout facing upwards, and the filter cup into the outer pot from bottom to top. Simultaneously, use the swivel surface of the lid to press against the bottom of the outer pot, causing the inner pot to move upwards. When the lid is finally screwed tightly onto the spout of the outer pot, the groove on the bottom of the inner pot is engaged with the annular cup sleeve, and the swivel surface axially abuts against the bottom of the outer pot. This ensures a tight seal between the groove and the annular cup sleeve, and between the edge of the inner pot's spout and the groove.

[0042] Subsequently, in the event of severe shaking or inversion, the clean water in the inner pot is sealed by the combined action of the one-way valve and the sealing ring, preventing the clean water from being contaminated.

[0043] This technology uses the protruding column of the lid to pressurize, eliminating the need for a separate pressurization space. When not in use, the water bottle can be folded and stored, effectively reducing its size and making it easier to carry.

[0044] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
