Description

Technical Field

[0001] This utility model belongs to the technical field of liquid filtration devices, specifically relating to an edible liquid filtration and adsorption device and container. Background Technology

[0002] In today's society, various types of purified water, mineral water, beverages, cooking oil, liquid condiments, alcoholic beverages, and other types of drinks are generally packaged in containers made of polymer materials, such as plastic. The production process of these polymer plastic containers typically involves heating the raw materials to a molten state, blowing them into shape under high temperature, and then cooling them to achieve a set shape. However, in this series of production steps, some plastic residue often inevitably remains inside the plastic containers. This residue mainly consists of plastic particles and a very small amount of chemical substances. These substances have been proven to pose potential health hazards. Long-term consumption of beverages containing these chemicals may adversely affect people's endocrine and reproductive systems, thus posing a serious threat to overall health.

[0003] In one existing technical solution, filtration is achieved by fixing multiple layers of filter screens inside the container mouth. These multiple layers of filter screens have a mesh filtration structure. Although they have a certain filtration effect on plastic particles in the edible liquid contained in the container, they are less effective at filtering other chemical substances, resulting in a single filtration function. Furthermore, the multiple layers of filter screens cannot be disassembled, making replacement or cleaning relatively inconvenient. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an edible liquid filtration and adsorption device and container to solve the problems of poor filtration effect and inconvenience of disassembly and assembly of existing filtration devices for edible liquids.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: On the one hand, an edible liquid filtration and adsorption device is provided, including a channel component, an annular holding component, a filter assembly and a sealing cap. The inner wall of the channel component is provided with an annular stepped groove. The filter assembly is movably disposed in the annular stepped groove and is held and fixed by the annular holding component. The channel component is provided with a connecting part one and a connecting part two along the axial direction. The connecting part one is connected to the sealing cap, and the connecting part two is used to connect to the mouth of a container. The filtration assembly includes a pre-filtration layer, an adsorption layer, and a fine filtration layer arranged along the axial direction, wherein the pre-filtration layer and / or the adsorption layer are graphene material layers or graphene composite material layers.

[0006] In a possible implementation, the annular retainer is threaded or interference-fitted within the channel member.

[0007] In one possible implementation, the top end of the annular clamping member is provided with an annular flange that covers the top end face of the channel member; The top of the annular flange has an arc-shaped protrusion; and / or, a sealing component is provided between the annular flange and the top end face of the channel member.

[0008] In one possible implementation, a cover pressure seal is provided on the inner side of the sealing cover, and the cover pressure seal has a sealing groove for at least partial embedding of the annular flange.

[0009] In one possible implementation, the bottom end of the annular pressing member is provided with a pressing part for pressing the filter assembly, and the annular stepped groove and the filter assembly are also provided with a gasket, and the pressing part presses the filter assembly onto the gasket.

[0010] In a possible implementation, the channel component is further provided with an annular mounting groove on the inner wall above the second connecting part. The second sealing component is provided in the annular mounting groove. The second sealing component includes an abutment part protruding inward toward the channel. The abutment part is provided with a stepped sealing groove for the bottle mouth of the container to be inserted.

[0011] In a possible implementation, the second sealing component further includes a support portion extending axially toward the filter assembly, the inner surface of which is an inclined surface.

[0012] In a possible implementation, both the first connecting part and the second connecting part are threaded connection structures.

[0013] In one possible implementation, the channel component is made of a polymer environmentally friendly material.

[0014] On the other hand, a container is also provided, including a bottle body with a bottle mouth and an edible liquid filtration and adsorption device as described in any of the above technical solutions connected to the bottle mouth.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This utility model discloses an edible liquid filtration and adsorption device and container. By combining a mesh filtration structure with graphene material, it can filter, intercept, and adsorb residual plastic particles and chemical substances in edible liquids. This achieves a better filtration effect and avoids the problem of poor adsorption of chemical substances in single mesh filtration. Furthermore, by movably installing the filter components and fixing them with an annular clamping member, the installation method facilitates the disassembly and assembly of the filter components, making them easy to clean or replace, and more convenient and practical.

[0016] Furthermore, while the annular pressing component presses and fixes the filter assembly, the annular flange can also form a stepped mating structure, which is more conducive to sealing. The top is set with an arc-shaped protrusion structure, which can improve the drinking comfort of the drinker.

[0017] Meanwhile, when the channel component is connected to the bottle mouth, the sealing component 2 can play a good sealing role, and the structural design is reasonable. Attached Figure Description

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0021] Please refer to Figure 1-6 As shown, an embodiment of this application provides an edible liquid filtration and adsorption device, including a channel component 1, an annular holding member 3, a filter assembly 4, and a sealing cap 2. The inner wall of the channel component 1 is provided with an annular stepped groove 13. The filter assembly 4 is movably disposed in the annular stepped groove 13 and is pressed and fixed by the annular holding member 3. The channel component 1 is provided with a connecting part 11 and a connecting part 2 12 along the axial direction. The connecting part 11 is connected to the sealing cap 2, and the connecting part 2 12 is used to connect to the bottle mouth 8 of a container.

[0022] The channel component 1 communicates with the connected container. It connects to the container's opening via a connecting part 12, forming a channel for the edible liquid to flow out of the container. As the edible liquid flows out through this channel, it is filtered and adsorbed by the inner filter assembly 4, thus achieving the filtration and adsorption effect. The filter assembly 4 is movably installed inside the channel component 1. Specifically, it is supported by an annular stepped groove 13 and then pressed by an annular pressing member 3, thus fixing the filter assembly 4. Because it is fixed by pressing, the detachable filter assembly 4 installed in the channel facilitates disassembly and assembly, making it easy to replace or clean. The sealing cap 2 is used to seal the channel component 1.

[0023] In the embodiments of this application, the filter assembly 4 may include a pre-filter layer 43, an adsorption layer 42 and a fine filter layer 41 arranged along the axial direction, wherein the pre-filter layer 43 and / or the adsorption layer 42 are graphene material layers or graphene composite material layers.

[0024] The pre-filtration layer 43 is used to intercept larger polymer particles and other impurities in the edible liquid, preventing these substances from entering the subsequent filtration and adsorption stages, avoiding clogging of the adsorption layer 42 and the fine filtration layer 41, and improving the working efficiency and service life of the entire filter assembly 4. The adsorption layer 42 is used to adsorb polymer particles and some harmful or unwanted chemicals in the edible liquid. The fine filtration layer 41 has extremely small pores, which can filter out extremely small particles and harmful chemical molecules that remain after being treated by the adsorption layer 42, further improving the purity of the edible liquid and ensuring that the edible liquid flowing out of the device meets safe drinking standards. Among them, the pre-filtration layer 43 and / or adsorption layer 42 are graphene material layers or graphene composite material layers. The graphene material pre-filtration layer 43 and / or adsorption layer 42 can form nanoscale channels (0.3–1 nm adjustable), which directly intercept particles larger than the channels (such as microplastics, bacteria, and macromolecular pollutants) through the size effect. With the structure of the thin film layer, it can intercept polymer plastic particles and some chemicals in edible liquids. The graphene composite material layer refers to the layered structure formed by combining graphene material with other materials for filtration and adsorption. For example, graphene and activated carbon material are combined to form adsorption layer 42. The adsorption layer 42 formed can have a rich pore structure and a huge specific surface area, which can efficiently adsorb small molecule harmful chemicals such as bisphenol A and phthalates, free silica, and heavy metals such as lead, nickel, and arsenic produced by the separation of polymer materials such as polymer plastics and polymer glass. For example, graphene combined with limiting materials, such as graphene composite polypropylene fiber or graphene composite polyester fiber, can effectively intercept residual larger polymer particles. Specifically, channel component 1 can be a cylindrical structure.

[0025] Through the above technical solution, the combination of mesh filter structure and graphene material can filter, intercept and adsorb residual plastic particles and chemical substances in edible liquids, thus achieving a better filtration effect and avoiding the problem of poor adsorption of chemical substances in single mesh filters. Furthermore, by movably installing the filter component 4 and pressing it with the annular clamping part 3, this installation method facilitates the disassembly and assembly of the filter component 4, making it easier to clean or replace, and is more convenient and practical.

[0026] In some embodiments, the annular retainer 3 is threaded or interference-fitted within the channel member 1.

[0027] In this way, the annular clamping member 3 is connected in the channel member 1 by thread or interference fit, which can not only clamp and fix the filter assembly 4 through axial movement during installation, but also facilitate the disassembly and assembly of the filter assembly 4, making it more convenient and practical.

[0028] Furthermore, the top end of the annular pressing member 3 is provided with an annular flange 31 that covers the top end face of the channel member 1.

[0029] In this way, the annular flange 31 can lock and limit the annular clamping member 3 when it is installed in place, and also facilitate the formation of a stepped sealing surface between the annular clamping member 3 and the channel member 1, thereby improving the sealing effect.

[0030] Based on this, in order to improve the comfort of the drinker, the top of the annular flange 31 is an arc-shaped protrusion structure 32. The annular flange 31 of the arc-shaped protrusion structure 32 can avoid the situation where the relatively sharp structure at the end of the channel component 1 can easily scratch the drinker's mouth, thus improving comfort and making it safer.

[0031] Meanwhile, a sealing component (not shown in the figure) can also be provided between the annular flange 31 and the top end face of the channel member 1. By providing a sealing component between the annular flange 31 and the channel member 1, and in conjunction with the stepped installation structure, the sealing effect can be further improved, preventing edible liquid entering the channel member 1 from leaking out through the gap between the annular retaining member 3 and the channel member 1. The sealing component can be a sealing ring.

[0032] In order to improve the sealing performance between the sealing cover 2 and the channel, in one embodiment, a cover pressure seal 5 is provided on the inner side of the sealing cover 2, and the cover pressure seal 5 is provided with a sealing groove 51 for at least partial embedment of the annular flange 31.

[0033] The cover seal 5 is a sealing gasket, and the inner shape of the other sealing covers 2 is adapted to it. The sealing groove 51 provided on the cover seal 5 is used for the arc-shaped protrusion of the annular flange 31 to be inserted. In this way, when the sealing cover 2 is installed on the channel member 1, the arc-shaped protrusion of the annular flange 31 can be inserted into the sealing groove 51 and pressed. This can improve the sealing performance between the sealing cover 2 and the channel member 1, and also make full use of the arc-shaped protrusion structure of the annular pressure member 3, which greatly improves the practicality.

[0034] In specific implementation, the bottom end of the annular pressing member 3 is provided with a pressing part 33 for pressing the filter assembly 4. The annular stepped groove 13 and the filter assembly 4 are also provided with a washer 7. The pressing part 33 presses the filter assembly 4 onto the washer 7. The pressing part 33 and the main body of the annular pressing member 3 form an L-shaped structure, which, when combined with the annular flange 31, makes the overall structure have a Z-shaped cross-section. Preferably, the annular pressing member 3 is installed in the channel member 1 by interference fit.

[0035] To achieve a seal between channel component 1 and container neck 8, please refer to... Figure 2 and Figure 3 As shown in the embodiment of this application, the channel component 1 is further provided with an annular mounting groove 14 on the inner wall above the connecting part 2 12. The annular mounting groove 14 is provided with a sealing component 2 6. The sealing component 2 6 includes an abutting part 61 protruding inward towards the channel. The abutting part 61 is provided with a stepped sealing groove 51 for the container bottle mouth 8 to be embedded.

[0036] The annular mounting groove 14 is used to install the sealing component 2 6. The sealing component 2 6 is an annular irregular sealing ring. The bottom abutment part 61 is provided with a stepped sealing groove 51 for the container mouth 8 to be inserted. When the container mouth is inserted, the mouth can abut against the stepped sealing groove 51. As it is rotated, it will become tighter and tighter, thereby achieving a tight seal and a better sealing effect.

[0037] Furthermore, the sealing component 6 also includes a support portion 62 extending axially toward the filter assembly 4, the inner surface of the support portion 62 being an inclined surface.

[0038] In this way, the support part 62 can abut against the inner wall of the channel component 1, so that when the container mouth 8 abuts against it, the force can be transmitted to the support part 62, thus providing better support. This also allows the support part 62 to fit tightly against the inner wall of the channel component 1, improving the sealing between the two. At the same time, the inclined surface can facilitate the decomposition of the water pressure force into outward and downward forces when there is high water pressure in the channel, thereby making the support part 62 close to the inside of the channel and improving the sealing effect.

[0039] Specifically, both the first connecting part 11 and the second connecting part 12 are threaded connection structures. The threaded connection structure can easily adapt to the bottle opening of the container, making it more adaptable and easier to connect.

[0040] Preferably, the channel component 1 is made of a high-polymer environmentally friendly material. Channel structures made of high-polymer environmentally friendly materials can have good stability.

[0041] In a preferred embodiment, the pre-filtration layer 43 is made of graphene composite fiber material, such as graphene composite polypropylene fiber or graphene composite polyester fiber, the adsorption layer 42 is made of graphene composite functional material, the composite material is mainly activated carbon, and the fine filtration layer 41 is made of ultra-microporous filter membrane, such as polyvinylidene fluoride (PVDF) ultra-microporous membrane.

[0042] The preparation methods of the pre-filtration layer 43, adsorption layer 42 and fine filtration layer 41 are as follows: 1. Preparation of pre-filter layer 43: Graphene and materials such as polypropylene fibers or polyester fibers are processed through carding, web laying, and hot pressing to form a fiber felt with a certain thickness and porosity, which serves as the pre-filter layer 43. The pore size and thickness of the fiber felt are controlled to effectively intercept larger particles of impurities; 2. Preparation of Adsorption Layer 42: Graphene and activated carbon are pulverized into suitable particle sizes. Titanium dioxide nanoparticles and other catalytic materials can also be added and thoroughly mixed. An appropriate amount of binder, such as polyvinyl alcohol (PVA), is added. The mixture is then pressed or coated to form an adsorption separation layer with a specific shape and thickness. During the preparation process, it is crucial to ensure the uniform distribution of activated carbon and catalytic materials to guarantee the adsorption and separation effect.

[0043] Preparation of fine filtration layer 41: A polyvinylidene fluoride (PVDF) ultraporous membrane is prepared using processes such as phase inversion or stretching. Parameters such as pore size, porosity, and thickness are controlled to meet the requirements of fine filtration. The prepared ultraporous membrane is then cut to a suitable size for later use.

[0044] Filter assembly 4 assembly: The pre-filter layer 43, adsorption layer 42 and fine filter layer 41 are stacked in sequence and fixed together by ultrasonic welding or hot pressing to form a complete filter assembly 4. The filter assembly 4 is installed in the pre-designed position inside the channel component 1, and then the filter assembly 4 is pressed and fixed to the channel component 1 by the annular clamping member 3.

[0045] It should be noted that the thickness of the channel component 1 can be selected and configured according to the applicable container size. For thinner packaging bottles, the wall thickness of the channel component 1 is also set to a corresponding wall thickness, and the dimensions of other components are also adjusted accordingly.

[0046] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
