If "first" or "second" is involved, it should be understood as being used to distinguish technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0033] In addition, unless otherwise defined, the technical terms and scientific terms used in this application are the same as those generally understood by those skilled in the art. The terms used in this application are only for describing specific embodiments, not for limiting this application. It should be understood that when used in this specification and the appended claims, the terms "include" and "comprise" indicate the presence of described features, wholes, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or their collections.

[0034] Traditional outdoor drinking water solutions, such as "static sedimentation filtration" and "simple filtration", have obvious limitations. Although the static sedimentation filtration method can remove some suspended matter, it has limited effect on the removal of microorganisms and chemical pollutants, and the operation is cumbersome and time-consuming. Although the simple filtration method is simple to operate, the filtration effect is unreliable and requires additional steps such as burning charcoal. It is not only inefficient, but may not completely eliminate harmful substances in the water.

[0035] Example: Figure 1-9 As shown, an outdoor water treatment device includes a cylinder 1 for containing water and a filter assembly 2 for filtering water. The cylinder 1 is provided with multiple groups, and the multiple groups of cylinders 1 are arranged up and down. Two adjacent groups of cylinders 1 are connected by threads. The bottom wall of the cylinder 1 is provided with a filter port 104 for connecting the two adjacent groups of cylinders 1 up and down. The filter assembly 2 is provided with multiple groups corresponding to the cylinder 1, and the filter assembly 2 is assembled with the filter port 104. The multiple groups of cylinders 1 arranged up and down are connected by threads. The structure is compact, easy to disassemble and assemble, and suitable for carrying during outdoor activities. Secondly, the gravity of the water itself is used to flow in the multiple groups of cylinders 1 to achieve filtration. There is no need to use external power to drive the water flow in the cylinder 1, but the force of gravity is used to promote the filtration of water. It is suitable for scenes where it is difficult to obtain electricity outdoors, solves the problem of water shortage, and meets the diverse needs of outdoor activity participants. Furthermore, by increasing or decreasing the number of cylinders 1, the capacity of the device can be adjusted to meet different filtering needs.

[0036] It is worth mentioning that the cylinder 1 is hollow and cylindrical with a bottom. The cylinder 1 is made of 304 stainless steel or 316L stainless steel. Both 304 stainless steel and 316L stainless steel have good corrosion resistance and can resist the erosion of corrosive substances such as acids, alkalis, salts, etc. that may exist in the outdoor environment, ensuring the long-term and stable use of the cylinder 1, thereby extending the service life of the entire device.

[0037] In order to improve the cleanliness of outdoor filtered drinking water, the cylinder 1 is sequentially provided with three groups from top to bottom, and the filter assembly 2 is correspondingly provided with three groups, each group of filter elements is provided corresponding to the cylinder 1, the inner ring wall provided with the filter port 104 is provided with an internal thread 601, and the filter element is provided with an external thread 701. The filter assembly 2 is threadedly connected with the filter port 104 to perform multi-stage filtration on the water source, which significantly improves the cleanliness of drinking water. The threaded connection design ensures the sealing performance between the filter assembly 2 and the cylinder 1, and prevents water leakage during the filtration process. At the same time, good sealing performance can also prevent external impurities from entering. The filter assembly 2 is inserted into the cylinder 1 to ensure the safety of drinking water. Secondly, the filter assembly 2 is connected to the filter port 104 of the cylinder 1 by threads, and installation and disassembly are very convenient. This design not only facilitates users to quickly assemble and disassemble outdoors, but also facilitates regular replacement or cleaning of the filter assembly 2 to ensure the filtering effect, increases the flexibility and adaptability of the device, and makes it more suitable for various outdoor environments. Moreover, due to the modular design, each component can be disassembled and assembled independently. Therefore, when not in use, each component can be stored or carried separately, which is convenient for saving space and reducing weight. At the same time, this design also makes the device safer and more convenient during transportation and storage.

[0038] In terms of the specific selection of filter elements, the filter components 2 are respectively the first filter component 201, the second filter component 202, and the third filter component 203 from top to bottom. The first filter component 201 is a compressed activated carbon filter element, which can filter out visible objects such as suspended matter, mud, leaves, and insects. The second filter component 202 is an ultrafiltration filter element, which can filter and remove most of the macromolecules and oil substances soluble in water. The third filter component 203 is a mixed filter element of ceramsite and medical stone, which can filter and adsorb some trace substances and improve the water quality at the same time. Through multiple groups of filter components 2 and the selection of different filter elements, outdoor water sources are filtered to enable outdoor activity participants to directly drink or boil water, cook rice, etc. outdoors. Each level of filter component 2 can filter and purify the water source in a targeted manner, thereby ensuring the excellent final water quality and providing outdoor activity participants with a convenient and safe way of drinking water. Secondly, each filter component 2 can be independently disassembled and replaced. Users can easily clean and replace the filter component 2 according to usage and needs to maintain the best working condition of the filtration system.

[0039] Furthermore, in order to improve the filtering efficiency, the same group of filter components 2 includes several filter elements, and the multiple groups of filter elements are arranged at equal angles in a circle on the bottom wall of the same group of cylinders 1. Preferably, the filter component 2 includes two to four filter elements for multi-channel filtration, so that more water can be processed per unit time to meet the needs of outdoor activity participants in emergencies or large amounts of water, thereby improving the filtering efficiency.

[0040] In terms of the specific assembly structure of the filter element and the cylinder 1, the cylinder 1 is sequentially provided with three groups from top to bottom to form a first cylinder 101, a second cylinder 102, and a third cylinder 103. The side wall of the third cylinder 103 is provided with a water outlet, and the water outlet is equipped with a water faucet 106. The first filter component 201 is threadedly connected to the filter port 104 of the first cylinder 101, the second filter component 202 is threadedly connected above the filter port 104 of the second cylinder 102, and the third filter component 203 is threadedly connected below the filter port 104 of the second cylinder 102 and is connected to the second filter component 202. The side wall of the third cylinder 103 is provided with a water outlet and is equipped with a water faucet 106, so that the filtered water can flow out conveniently, which is convenient for users to take water and use. Secondly, each filter component 2 is connected to the cylinder 1 in a threaded connection manner, which makes installation and disassembly simple and quick, and users can easily complete it without professional tools, which is suitable for outdoor environments.

[0041] It should be noted that in order to prevent dust and fallen leaves in the outdoor environment from entering the first cylinder 101 when the device is filtering water, the present embodiment also includes a cover 105. The cover 105 covers the top wall of the first cylinder 101, effectively preventing dust, fallen leaves and other impurities in the outdoor environment from entering the cylinder 1, thereby protecting the purity of the water source and preventing the filter component 2 from being contaminated or blocked, thereby ensuring the normal operation and filtering effect of the filtration system.

[0042] Specifically, first pour the water to be filtered into the first cylinder 101, and then cover the lid 105. The water in the first cylinder 101 passes through the first filter component 201 from the periphery to the interior of the first filter component 201, and the suspended matter, silt, leaves, insects and other visible objects are filtered out. After slowly passing through the first filter component 201 by gravity, it flows into the second cylinder 102 from the filter port 104 of the first cylinder 101. The water in the second cylinder 102 passes through the second filter component 202 from the periphery to the interior of the second filter component 202, and most of the visible objects such as suspended matter, silt, leaves, and insects are filtered out. Some macromolecules and oil substances that are partially soluble in water slowly pass through the second filter component 202 by gravity. Since the second filter component 202 and the third filter component 203 are arranged opposite to each other and are connected, they flow into the third filter component 203 from the filter port 104 of the second cylinder 102. The third filter component 203 filters and adsorbs some trace substances and improves the water quality. After passing through the third filter component 203, the water drips into the third cylinder 103 under the action of weight, and the filtered water can be obtained by turning on the faucet 106.

[0043] There is an electronic display screen at the upper position of the faucet 106, and the electronic display screen is assembled on the outer wall of the third cylinder 103. An infrared flow meter is arranged in the middle of the faucet 106, and the infrared flow meter is electrically connected to the electronic display screen. The electronic display screen has a built-in PLC microcomputer. Since the filter element has a filtration saturation, the filtration life of the filter element is calculated by the infrared flow meter and the average pollutant concentration. When the filtration limit is reached, the electronic display screen will light up in red to remind the user to replace the filter element.

[0044] In order to prevent the water in the upper cylinder 1 from seeping into the lower cylinder 1 through the filter port 104 and affecting the filtering effect, the present embodiment also includes a silicone sheet, which is arranged at the connection between the filter component 2 and the filter port 104, effectively preventing the water in the upper cylinder 1 from directly seeping into the lower cylinder 1 without being fully filtered. This design ensures that the water in each section of the cylinder 1 can be fully filtered through the corresponding filter component 2, thereby improving the overall filtering effect and ensuring the purity of the outlet water quality.

[0045] In order to disinfect and sterilize the filtered drinking water, the present embodiment further includes a shell 4 and an ozone sterilizer 5. The shell 4 is threadedly connected to the third cylinder 103. The ozone sterilizer 5 is assembled in the shell 4 and is used to sterilize and disinfect the water in the third cylinder 103. Ozone sterilization is adopted, and the sterilization effect and durability are better. In addition, the outdoor water source needs to be equipped with a sterilization function to ensure drinking safety. It is suitable for groundwater, tap water, lake water, etc. in outdoor environments. The ozone sterilizer 5 can effectively kill bacteria, viruses and other microorganisms in the water to ensure that the filtered drinking water meets the standards for safe drinking, which greatly improves the safety of drinking water in outdoor environments. While killing bacteria, ozone sterilization can also remove odor and chroma in the water, improve the taste of water quality, and make drinking water more refreshing and delicious. Secondly, ozone sterilization has the characteristics of good durability and can maintain the sterile state in the water for a long time. Even during storage or transportation, it can effectively prevent bacteria from breeding and ensure water quality safety.

[0046] It is worth mentioning that the shell 4 is hollow and cylindrical with a bottom, and the shell 4 is made of 304 stainless steel or 316L stainless steel.

[0047] In terms of the specific structure of the ozone sterilizer 5 sterilizing the third cylinder 103, the present embodiment also includes a silicone tube 501 and a check valve 502. The silicone tube 501 is used to connect the air outlet end of the ozone sterilizer 5 and the filter port 104 of the third cylinder 103. The check valve 502 is connected to the silicone tube 501 for the ozone sterilizer 5 to flow unidirectionally to the filter port 104. The silicone tube 501 directly connects the air outlet end of the ozone sterilizer 5 with the filter port 104 of the third cylinder 103, ensuring that ozone can directly and effectively enter the third cylinder 103, fully sterilize the filtered water, and ensure the sterilization effect. Secondly, the setting of the check valve 502 allows ozone to flow only unidirectionally to the filter port 104, effectively preventing the backflow of water in the third cylinder 103 during the sterilization process, thereby ensuring the stability and safety of the sterilization process.

[0048] In order to prevent the water in the third cylinder 103 from seeping into the shell 4 under the action of gravity, the fixed end of the ozone sterilizer 5 is assembled at the bottom of the shell 4, and the battery assembly port of the ozone sterilizer 5 is set downward. The ozone sterilizer 5 is a 300-500 mg / H DC ozone generator, which can provide stable and efficient ozone output to ensure that the water in the third cylinder 103 is fully and evenly sterilized. Four 1.5V dry batteries 503 are used as driving power sources. The generated ozone disinfects the water in the third cylinder 103, which can be directly drunk or used for boiling water, cooking, etc. A mounting hole is opened at the bottom of the shell 4, and the mounting hole corresponds to the battery assembly port of the ozone sterilizer 5, which is convenient for users to assemble dry batteries 503 in outdoor environments without external power supply, thereby improving the convenience and flexibility of use. It is suitable for various outdoor environments, whether it is camping, hiking or emergency rescue, etc., and can conveniently provide effective sterilization for drinking water.

[0049] It is worth mentioning that the aperture of the filter port 104 of the second barrel 102 is smaller than the aperture of the filter port 104 of the first barrel 101 , and the aperture of the filter port 104 of the second barrel 102 is larger than the aperture of the filter port 104 of the first barrel 101 .

[0050] In order to facilitate the outdoor use of the device, its volume needs to be controlled so that the treatment device can be placed in a household car. The filter element is a standard part with a length of 20 cm. In order to reduce the mold cost, the height of the cylinder 1 is designed to be 25 cm ± 2 cm, and the height of the shell 4 is 15 cm ± 2 cm. When the height of the three groups of cylinders 1 is 25 cm and the height of the shell 4 is slightly 15 cm, the total height of the device is 90 cm, and the capacity of a common family car trunk is usually around 450 liters, which usually corresponds to a width between 1000 cm and 1200 cm, a height between 400 cm and 550 cm, and a depth ranging from 900 cm to 1100 cm, so that the device can be easily placed in a family car. Furthermore, the diameter of the cylinder 1 is 300 to 375 cm, and the diameter of the shell 4 is 300 to 375 cm. By precisely controlling the dimensions of the cylinder 1 and the shell 4, the total height and diameter of the entire device are suitable for placement in a common family car trunk, greatly improving the portability of the device and making it convenient for users to carry and use it during outdoor activities. Secondly, the compact design of the device makes it occupy less space, which is not only convenient for placement in a car, but also for use in outdoor camping sites or other limited spaces.

[0051] Reference Figures 5 to 9The present embodiment provides a structure in which a cylinder 1 is threadedly connected to a cylinder 1, a first connecting portion 6 in a U shape is provided on the top of the cylinder 1, a second connecting portion 7 in an inverted U shape is provided on the bottom wall of the cylinder 1, an internal thread 601 is provided on the inner side wall of the first connecting portion 6, an external thread 701 meshing with the internal thread 601 is provided on the inner side wall of the second connecting portion 7, the two groups of cylinders 1 arranged upper and lower are threadedly connected with the first connecting portion 6 and the second connecting portion 7 through the first connecting portion 6 and the second connecting portion 7 through the inverted U shape, so as to prevent the risk of water in the cylinder 1 from seeping out through the connection between the cylinder 1 and the head cylinder 1, thereby ensuring the sealing and safety of the device.

[0052] Furthermore, the present embodiment also includes multiple groups of sealing rings. A support block 602 is provided on the inwardly protruding first connection part 6. The support block 602 is used to support an inner side wall of the second connection part 7. A sealing ring is provided between the support block 602 and the second connection part 7. A sealing ring is provided between the first connection part 6 and the second connection part 7. By providing sealing rings between the first connection part 6 and the second connection part 7 and between the support block 602 and the second connection part 7, the sealing performance of the connection is further enhanced, and water is effectively prevented from seeping out of the connection. Secondly, the design of the sealing ring increases the friction of the connection, so that the connection between the cylinders 1 is more stable and not easy to loosen, thereby improving the stability of the entire device.

[0053] In order to prevent the two groups of cylinders 1 from rotating and causing water leakage after being threadedly assembled, this example also includes a first magnetic block 603, and a second magnetic block 604 is arranged on the outer wall of the cylinder 1. The magnetic poles of the first magnetic block 603 and the second magnetic block 604 are arranged with opposite names. The first magnetic block 603 is slidably assembled with the first connecting part 6 and moves back and forth toward the second magnetic block 604. When the upper and lower groups of cylinders 1 are threadedly connected, the first magnetic block 603 and the second magnetic block 604 attract each other to limit the rotation of the cylinder 1 toward the upper group. Through the attraction of magnetic force, the connection between the two groups of cylinders 1 is more stable. The design of the first magnetic block 603 and the second magnetic block 604 attracting each other effectively prevents water leakage caused by accidental rotation of the upper and lower groups of cylinders 1 after threaded connection, thereby ensuring the overall sealing performance of the device. Secondly, after the threaded connection is completed, the first magnetic block 603 and the second magnetic block 604 will automatically attract each other, without the need for additional fixing measures, thereby simplifying the operating steps and improving work efficiency.

[0054] It should be noted that the first magnetic block 603 is designed in an arc shape with an arc of 10°±2°. The first magnetic block 603 is provided with multiple groups, and the multiple groups of first magnetic blocks 603 are equidistantly arranged along the circumference of the axis of the cylinder 1. Since the first magnetic block 603 is designed in an arc shape and is equidistantly arranged along the circumference of the axis of the cylinder 1, when the upper and lower groups of cylinders 1 are threadedly connected, the multiple groups of magnetic blocks can generate magnetic attraction at the same time, thereby enhancing the stability of the connection and preventing water leakage caused by accidental rotation. Secondly, the uniform distribution of the multiple groups of magnetic blocks makes the force on the connection more uniform, further improves the sealing performance of the connection, effectively prevents water from seeping out of the connection, and ensures the overall sealing effect of the device. Furthermore, the first magnetic block 603 with an arc design can better adapt to the curved shape of the outer wall of the cylinder 1, ensuring a close fit between the magnetic block and the cylinder 1. At the same time, the equidistant arrangement of the multiple groups of magnetic blocks enables the device to adapt to cylinders 1 of different specifications and sizes, thereby improving the adaptability and flexibility of the device.

[0055] In order to facilitate the disassembly between the cylinder bodies 1 and reduce the interference of the first magnetic block 603 on the cylinder body 1 during disassembly, a side wall of the second connecting portion 7 facing outward is inclined to form a first inclined surface 702, and a second inclined surface 6031 is provided at one end facing the first magnetic block 603. When the two groups of cylinder bodies 1 are separated, the first inclined surface 702 cooperates with the second inclined surface 6031 to push the first magnetic block 603 to move outward. Furthermore, the outer side wall of the second connecting portion 7 is connected to the third magnetic block 703, and the magnetic poles of the third magnetic block 703 and the first magnetic block 603 are set with the same name, so as to push the first magnetic block 603 to move outward when the two groups of cylinder bodies 1 are separated. Of course, the first magnetic block 603 is provided with a limiting portion 6032 for preventing it from separating from the first supporting portion. Through the cooperation of the first inclined surface 702 and the second inclined surface 6031, and the setting of the same magnetic poles of the third magnetic block 703, when the two groups of cylinder bodies 1 are separated, the first magnetic block 603 can be automatically pushed outward, thereby reducing manual operation and simplifying the disassembly process.

[0056] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application.
