Description

Technical Field

[0001] This utility model belongs to the technical field of water purification devices, and in particular relates to a filtration and purification component. Background Technology

[0002] During outdoor activities, obtaining clean and safe drinking water is often a major challenge due to the uncertainty of water sources. Directly drinking natural water sources such as rivers and lakes may contain various harmful substances, posing a threat to human health.

[0003] Existing outdoor filtration devices generally fall into two categories: one is the design described in CN204146561U, a drinking water filtration device for outdoor mountaineering water cups. This device has an outer edge at the top that can be snapped onto the opening of a water storage container, allowing water to pass through and enter the container. However, this design lacks a container for storing the filtered spring water, requiring continuous pouring of the water into the device for filtration. Furthermore, this design prevents the device from being moved during filtration; the user can only carry it after filtration is complete. One approach is not convenient enough. Another approach, as described in CN214880830U, is an energy-saving portable drinking water treatment device. This device has a filter inside the bottle and divides the bottle into an upper and lower section, which are respectively a first water storage chamber and a second water storage chamber. Water can pass through the first water storage chamber, be purified by the filter, and then flow into the second water storage chamber for storage. This structure looks like a bottle from the outside, which solves the problem of portability and the need to constantly pour water. However, because the internal space of this solution is fixedly divided into two areas, the water storage capacity and the amount of water purified at one time are relatively small. Therefore, further improvements are needed. Summary of the Invention

[0004] To address the aforementioned technical problems, this utility model provides a filtration and purification component.

[0005] A filtration and purification assembly includes a funnel lined with a flexible material, with an inlet and an outlet at its upper and lower ends, respectively. The funnel has a water section and a filtration section arranged sequentially from top to bottom. The filtration section contains a filtration and purification device, and the water section can automatically contract or expand. The upper end of the funnel also has a connecting part for detachable connection to the opening of a water storage container. Water to be filtered and purified enters the water section of the funnel through the inlet. As more water is added, the water section gradually expands until it is fully extended. After being filtered and purified by the filtration and purification device within the filtration section, the water flows out through the outlet. As the amount of water decreases, the water section gradually and automatically contracts until it is completely retracted.

[0006] By adopting the above technical solution, the inner funnel is made of a flexible material (such as silicone, rubber, etc.), and a filtration and purification device is installed in the filtration section to filter and purify the water source. The water to be filtered and purified can be injected into the filtration section all at once; the weight of the water stretches and expands the originally automatically contracting filtration section, allowing it to store more water. After the water is purified by the filtration and purification device, it flows out, and the water in the filtration section continuously decreases, causing the filtration section to overcome the weight of the water and automatically contract and reset. Therefore, this filtration and purification component can conveniently obtain clean and safe drinking water, is highly efficient in operation, and automatically contracts for easy storage. The connecting part allows for detachable connection to the mouth of a water storage container. Simply fix the component to the mouth of the water storage container, and the container mouth can be sealed with a lid. From the outside, it still looks like a regular container. This water storage container, once sealed with its lid, can be carried around for filtration without waiting for it to finish or constantly refilling the filter. During filtration, the bottom of the funnel or inner liner can be extended to the bottom of the container's inner cavity. As filtration progresses, the amount of potable water in the container increases while the amount of water in the sludge section decreases, causing the sludge section to automatically contract. This frees up space within the container for potable water storage. After filtration, the sludge section completely retracts, filling the container with potable water. Therefore, this structure eliminates the need to divide the container, allowing for a larger volume of water filtered at once compared to existing technologies, without affecting the container's storage capacity. It effectively solves the problems associated with existing technologies.

[0007] In some embodiments, the sidewalls of the Chushui section have a continuous corrugated structure, enabling it to automatically contract or be stretched and expanded.

[0008] In these embodiments, by designing the sidewalls of the Chushui section as a corrugated structure and combining it with its flexible material, it can automatically shrink more efficiently, shrink to a greater extent, and be easier to store; at the same time, it can be stretched out to a greater extent, and can store more water to be filtered and purified.

[0009] In some embodiments, the filtration and purification device includes a housing and a filter element placed inside the housing. The housing consists of a cover and a shell. The cover is detachably provided at the upper opening of the shell, and the top surface of the cover and the bottom surface of the shell are respectively provided with a plurality of water inlet holes and water outlet holes.

[0010] In these embodiments, the housing is designed as a combination of a cover and a housing, and the cover is removable for easy replacement of the filter element.

[0011] In some embodiments, the filter element is provided with a filter sponge and a combined filter element from top to bottom, and the combined filter element is a mixture of one or more of the following: microporous antibacterial balls, quartz sand particles, and activated carbon.

[0012] In these embodiments, the filter cartridge adopts a design of filter sponge and combined filter cartridge, which can basically effectively meet the user's access to water sources outdoors. The microporous antibacterial balls in the combined filter cartridge have antibacterial and bactericidal effects, the quartz sand particles can be used to filter and block suspended solids in the water, and the activated carbon can adsorb and filter chlorine, organic matter (heavy metals, pesticides, chemicals, etc.) and odors in the water.

[0013] In some embodiments, the activated carbon is iodine-value granular coconut shell activated carbon for water purification.

[0014] In these embodiments, the iodine-value granular coconut shell activated carbon contains a large amount of iodine, which can better remove heavy metals and radioactive substances from water; moreover, the coconut shell activated carbon has a smaller pore size and stronger adsorption performance.

[0015] In some embodiments, the filter element also includes an upper filter screen disposed above the filter sponge.

[0016] In these embodiments, by placing a filter screen above the filter sponge, impurities such as sand and floating matter can be initially filtered out, while also improving the service life of the filter sponge and the combined filter element.

[0017] In some embodiments, the filter element further includes a lower filter screen disposed below the combined filter element.

[0018] In these embodiments, by setting a lower filter screen below the combined filter element, it is possible to prevent the microporous antibacterial balls, quartz sand particles, or activated carbon in the combined filter element from falling off, and also to prevent impurities from entering and contaminating the combined filter element.

[0019] In some embodiments, the connecting portion is a rigid hanging edge that extends radially outward from the upper port of the liner funnel.

[0020] In these embodiments, the radially outwardly extending hanging edge has a simple and practical structure, and can be efficiently and conveniently attached to the mouth of the water storage container; and it is designed to be rigid so that it can support the entire filtration and purification assembly and the added water to be filtered and purified.

[0025] To make the technical solution of this utility model clearer, the following description is in conjunction with the appendix. Figures 1 to 4 This specification provides a detailed description of the present invention. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the scope of protection of the present invention.

[0026] A filtration and purification component, such as Figure 1-3 As shown, it includes an inner funnel 1, which is made of a flexible material such as silicone or rubber and is stretchable; and its upper and lower ends are respectively provided with an inlet 11 and an outlet 12; the inner funnel 1 is provided with a water section 13 and a filter section 14 from top to bottom, wherein the water section 13 can automatically shrink or be stretched and expanded, and the filter section 14 is provided with a filtration and purification device 2.

[0027] During filtration, the water to be filtered and purified is poured into the water section 13 of the inner liner funnel 1 through the inlet 11. As the water to be filtered and purified is continuously added, the water section 13 is gradually stretched until it is fully expanded because the inner liner funnel 1 is made of a flexible material with stretchability, so that it can store more water. This avoids the need for continuous water addition and is more efficient, allowing more water to be filtered at once. When the water section 13 is full of water to be filtered and purified, the water flows out from the outlet 12 through the filtration and purification device 2 in the filtration section 14. At this time, the water in the water section 13 continues to decrease until it is completely filtered and purified. The water section 13 gradually and automatically contracts under its own elasticity until it is completely retracted, which is convenient for storage and makes room for water storage.

[0028] As a preferred option, the sidewall of the Chushui section 13 is designed with a continuous corrugated structure. This structure, combined with its flexible material, allows for more efficient automatic shrinkage, a greater degree of shrinkage, and easier storage. At the same time, it can also be stretched out to a greater extent, allowing it to store more water to be filtered and purified.

[0029] Preferably, the filtration and purification device includes a housing 22 and a filter element, with the filter element placed inside the housing 22. The housing 22 is designed to include a cover 221 and a housing 222. The housing 222 has a cavity for accommodating the filter element and an opening at the top. The cover 221 is detachably fitted onto the opening at the top of the housing 222. The detachable structure can be, but is not limited to, threaded connection, snap-fit, fastening, screw or bolt connection, etc. The detachable cover 221 facilitates filter element replacement. In addition, the top surface of the cover 221 has a water inlet hole, and the bottom surface of the housing 222 has a water outlet hole. The water to be filtered and purified flows in through the water inlet hole and flows out through the water outlet hole.

[0030] Preferably, the filter element includes a filter sponge 24 and a combined filter element 25; wherein the filter sponge 24 is placed on top of the combined filter element 25, and is usually made of materials such as polyurethane, polyester, and polyether, and is mainly used for mechanical filtration to help remove suspended particles, debris, and other solid particles or impurities from the water; the combined filter element 25 is a mixture of one or more of the following: microporous antibacterial balls, quartz sand particles, and activated carbon. The microporous antibacterial balls have antibacterial and bactericidal effects, the quartz sand particles can be used to filter and block suspended solids in the water, and the activated carbon can adsorb and filter chlorine, organic matter (heavy metals, pesticides, chemicals, etc.), and odors in the water.

[0031] As a preferred option, the activated carbon in the combined filter element 25 is preferably iodine-value granular coconut shell activated carbon for water purification. Firstly, iodine-value granular coconut shell activated carbon for water purification contains a large amount of iodine, which can better remove heavy metals and radioactive substances from the water. Secondly, coconut shell activated carbon has a smaller pore size and stronger adsorption performance.

[0032] Preferably, the filter element also includes an upper filter screen 23, which is located above the filter sponge 24. The upper filter screen 23 can be selected with a mesh size of 500-800 as needed, and the material can be food-grade nylon mesh. It can be used for preliminary filtration of impurities such as sand and floating matter, and can also improve the service life of the filter sponge 24 and the combined filter element 25.

[0033] Preferably, the filter element also includes a lower filter screen 26, which is located below the combined filter element 25. The lower filter screen 26 can be selected with a mesh size of 100-800 as needed, and the material can be food-grade nylon mesh. It can be used to prevent microporous antibacterial balls, quartz sand particles, or activated carbon from falling into the combined filter element 25, and can also prevent impurities from entering and contaminating the combined filter element 25.

[0034] Preferably, in order to facilitate the connection of the filtration and purification component to the water storage container, a connecting part needs to be provided at the upper port of the inner lining funnel. This connecting part can be a hanging edge 15 extending radially outward, a U-shaped bayonet with an outwardly turned edge, a structure with a pull rope tightening opening, or any other form of structure that facilitates connection with the water storage container. Among them, the hanging edge 15 structure also needs to be designed to be rigid so that it can support the entire filtration and purification component and the added water to be filtered and purified.
