Description

Technical Field

[0001] This invention relates to the field of water purification equipment technology, and in particular to a composite cation exchange particle, a filter element, a method for preparing the filter element, and a shower head. Background Technology

[0002] Showerheads are the terminal of a household water system. During daily water use, limescale and bacteria can easily accumulate, leading to clogging and bacterial growth, which can pose potential health risks. To address these issues, many showerhead products with replaceable filters have emerged on the market. These filters consist of PP cotton, activated carbon, and filter membranes, primarily achieving scale and bacteria inhibition through physical barriers and electrostatic adsorption.

[0003] However, these shower filter cartridges have the following problems:

[0004] 1. Filters based on physical barriers, filter membrane pore size, and electrostatic adsorption are prone to saturation in terms of filtration and scale inhibition functions, resulting in short filter lifespan and high replacement costs.

[0005] 2. Filter cartridges made of scale-inhibiting and antibacterial chemical materials based on silver ion and zinc ion ion replacement have a relatively fast release rate of silver ions and zinc ions. The consumption rate in bath water is difficult to control, resulting in high concentrations in the early stage, causing discomfort to the user's skin; in the later stage, the concentration is insufficient, and the scale-inhibiting and antibacterial effect drops sharply, or even loses its corresponding effect.

[0006] 3. Aromatherapy essential oils can usually only be combined with soaking in the bath, and there are currently no shower products that can provide a long-lasting aromatherapy effect to the water. Summary of the Invention

[0007] The purpose of this invention is to provide a composite cationic particle, a filter element, a method for preparing the filter element, and a shower head, aiming to solve the problems of short service life and high replacement cost of existing shower head filter elements.

[0008] In a first aspect, embodiments of the present invention provide a composite cationic particle, wherein, by mass percentage, the composite cationic particle is composed of 20%-40% sodium hexametaphosphate, 10%-20% sodium tripolyphosphate, 10%-20% sodium polyacrylate, 1%-5% zinc oxide, 2%-5% silver powder, and 30%-50% calcium acetate.

[0009] Secondly, embodiments of the present invention provide a filter element, which, by mass percentage, is composed of 0.01%-0.1% silver powder, 60%-80% EVA resin, 1% alkyl polyether, 5%-20% calcium acetate, 5%-10% aromatherapy essential oil, and 5%-10% of the composite cationic particles as described in claim 1.

[0010] Thirdly, embodiments of the present invention provide a method for preparing a filter element, comprising:

[0011] Dissolve 20%-40% sodium hexametaphosphate, 10%-20% sodium tripolyphosphate and 10%-20% sodium polyacrylate in warm water at 35-40℃ by mass percentage, and stir at a constant temperature for more than 2 hours until fully mixed to obtain the first solution.

[0012] Add 1%-5% zinc oxide and 2%-5% silver powder to the first solution and stir for 6-8 hours until fully mixed and dispersed to obtain the second solution;

[0013] Add 30%-50% calcium acetate to the second solution and stir at 80-90℃ for 12-16 hours to obtain temporary composite cationic particles;

[0014] The temporary composite cationic particles are dried at 40-60℃ for 36-72 hours to obtain the final composite cationic particles.

[0015] By weight percentage, 0.01%-0.1% silver powder, 60%-80% EVA resin, 1% alkyl polyether, 5%-20% calcium acetate, 5%-10% aromatherapy essential oil, and 5%-10% final composite cationic particles are stirred and mixed for 2-4 hours, and then mixed by a screw granulator to produce masterbatch, thus obtaining a semi-finished product.

[0016] The semi-finished product is subjected to extrusion or injection molding processes, and then formed using a filter element mold to obtain the filter element.

[0017] Fourthly, embodiments of the present invention provide a filter element, which, by weight percentage, is composed of 80%-90% plastic and 10%-20% composite silver ion particles as described in claim 1.

[0018] Fifthly, embodiments of the present invention provide a shower head, comprising: a spray head, a handle, and a filter element as described in the second or fourth aspect, wherein the spray head and the handle are detachably connected, the spray head is provided with a water outlet, the handle is provided with a water outlet channel communicating with the water outlet, and the filter element is disposed in the water outlet channel.

[0019] This invention discloses a composite cationic granule, a filter element, a method for preparing the filter element, and a shower head. By mass percentage, the composite cationic granule comprises 20%-40% sodium hexametaphosphate, 10%-20% sodium tripolyphosphate, 10%-20% sodium polyacrylate, 1%-5% zinc oxide, 2%-5% silver powder, and 30%-50% calcium acetate. The composite cationic granule of this invention can slowly release multiple cations into the water. These cations can be uniformly adsorbed in the additives, forming chelates. Some cations can replace calcium and magnesium ions in the water, thus providing a corresponding scale-inhibiting effect on the shower head. The scale-inhibiting effect is excellent, and because it is a chemical scale inhibitor, it avoids the saturation of the scale-inhibiting function seen with physical scale inhibitors, resulting in a longer service life. Furthermore, the preparation process of the composite cationic granule also forms a porous structure inside the granules. This porous structure controls the extremely slow dissolution of ppb-level cations adsorbed on the material surface into the water, thereby achieving highly efficient and long-lasting antibacterial properties, improving the service life of the filter element, and reducing replacement costs.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0036] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0037] This invention provides a composite cationic particle, which, by mass percentage, is composed of 20%-40% sodium hexametaphosphate, 10%-20% sodium tripolyphosphate, 10%-20% sodium polyacrylate, 1%-5% zinc oxide, 2%-5% silver powder, and 30%-50% calcium acetate.

[0038] In this embodiment, the composite cationic particles can slowly release a variety of cations, among which the slowly released silver ions can play a good antibacterial role, and some of the cations can replace calcium and magnesium ions in the water, thereby playing a corresponding scale-inhibiting effect on the shower head.

[0039] In a preferred embodiment, the composite cationic particles, by mass percentage, consist of 25%-35% sodium hexametaphosphate, 12%-18% sodium tripolyphosphate, 12%-18% sodium polyacrylate, 2%-4% zinc oxide, 2%-4% silver powder, and 35%-45% calcium acetate.

[0040] In this embodiment, the antibacterial and bacteriostatic effects of the composite cationic particles are further enhanced, and the scale inhibition effect is also correspondingly enhanced.

[0041] In a preferred embodiment, the composite cationic particles, by mass percentage, consist of 27%-33% sodium hexametaphosphate, 13%-17% sodium tripolyphosphate, 13%-17% sodium polyacrylate, 2%-4% zinc oxide, 2%-4% silver powder, and 37%-43% calcium acetate.

[0042] In this embodiment, the antibacterial and bacteriostatic effects of the composite cationic particles are further enhanced, and the scale inhibition effect is also correspondingly enhanced.

[0043] In a preferred embodiment, the composite cationic particles, by mass percentage, consist of 27%-30% sodium hexametaphosphate, 13%-15% sodium tripolyphosphate, 13%-15% sodium polyacrylate, 2%-4% zinc oxide, 2%-4% silver powder, and 37%-40% calcium acetate.

[0044] In this embodiment, the antibacterial and bacteriostatic effects of the composite cationic particles are further enhanced, and the scale inhibition effect is also correspondingly enhanced.

[0045] In a preferred embodiment, the composite cationic particles, by mass percentage, consist of 28% sodium hexametaphosphate, 14% sodium tripolyphosphate, 14% sodium polyacrylate, 3% zinc oxide, 3% silver powder, and 38% calcium acetate.

[0046] In this embodiment, the antibacterial and bacteriostatic effects of the composite cationic particles are better than those of the above embodiments, and the scale inhibition effect is also relatively better.

[0047] Please see Figure 2 This embodiment also provides a shower head, including: a spray head 1, a handle 2 and a filter element 3. The spray head 1 and the handle 2 are detachably connected. The spray head 1 is provided with a water outlet, the handle 2 is provided with a water outlet channel communicating with the water outlet, and the filter element 3 is disposed in the water outlet channel.

[0048] The detachable connection between the spray head 1 and the handle 2 allows for easy removal of the spray head 1 for cleaning or replacement of the filter element 3. This helps ensure unobstructed water flow from the shower head, thereby improving the shower head's performance and enhancing the user experience.

[0049] The following is a detailed explanation of filter element 3:

[0050] The core technology of the shower head in this embodiment is the replaceable filter cartridge inside the handle 2. Based on the internal assembly of the filter cartridge 3, this embodiment classifies the filter cartridge 3 into several types, including scale-inhibiting and antibacterial filter cartridges, aromatherapy filter cartridges, and aromatherapy scale-inhibiting and antibacterial filter cartridges. Users can replace different components of the filter cartridge according to their needs. For example, if a user only needs the shower head to have scale-inhibiting and antibacterial effects, they can choose the scale-inhibiting and antibacterial filter cartridge; or, if a user does not need scale-inhibiting and antibacterial effects but is interested in aromatherapy, they can choose the aromatherapy filter cartridge; or, if a user needs both scale-inhibiting and antibacterial effects and aromatherapy, they can choose the aromatherapy scale-inhibiting and antibacterial filter cartridge.

[0051] Among them, scale-inhibiting and antibacterial filter cartridges and aromatherapy scale-inhibiting and antibacterial filter cartridges have longer and more stable release cycles. While aromatherapy filter cartridges also meet the slow-release requirement, they continue to release into the air, resulting in a shorter lifespan compared to scale-inhibiting and antibacterial filter cartridges. Therefore, a dual-layer, separate combination of scale-inhibiting and antibacterial filter cartridges and aromatherapy filter cartridges can be selected to allow for flexible replacement of the aromatherapy filter cartridge. For details, please refer to [link / reference]. Figure 3-8 The filter element 3 includes an outer core 4 and an inner core 5. The outer core 4 has a receiving part 6, and the inner core 5 is disposed in the receiving part 6. The design of the outer core 4 and the inner core 5 makes them easier to remove. When one of the outer core 4 and the inner core 5 loses its corresponding function or is damaged, only the part that has lost its corresponding function or is damaged needs to be replaced, instead of replacing the entire filter element, thus saving costs. Secondly, the design of the outer core 4 and the inner core 5 allows users to easily clean and maintain the filter element, extending its service life.

[0052] In this embodiment, the outer core 4 and the inner core 5 are connected in the following ways: the receiving part 6 is spiral-shaped, the outer surface of the inner core 5 is spiral-shaped, and the inner core 5 is provided with a water outlet channel 7 (e.g., Figure 3-5 (As shown); By rotating the inner core 5 into the receiving part 6, this design achieves a stable connection between the outer core 4 and the inner core 5, while also enabling a detachable connection between the outer core 4 and the inner core 5, allowing for individual replacement of the outer core 4 and the inner core 5; alternatively, the receiving part 6 can be configured as a circular through hole, and the outer surface of the inner core 5 can be configured as an irregular structure (such as...). Figure 6-8As shown, when the inner core 5 is installed into the receiving part 6, there is a gap between the outer surface of the inner core 5 and the receiving part 6. Water can flow through the gap through the entire filter element 3. This design eliminates the need for an additional water flow channel 7 and makes installation more convenient. Simply push or pull the inner core 5 into the receiving part 6.

[0053] In this embodiment, the aromatherapy scale-inhibiting and antibacterial filter element is composed of 0.01%-0.1% silver powder, 60%-80% EVA resin, 1% alkyl polyether, 5%-20% calcium acetate, 5%-10% aromatherapy essential oil, and 5%-10% composite cationic particles.

[0054] Please see Figure 1 The present invention also provides a method for preparing a filter element, comprising:

[0055] S101: Dissolve 20%-40% sodium hexametaphosphate, 10%-20% sodium tripolyphosphate and 10%-20% sodium polyacrylate in warm water at 35-40℃ by mass percentage, and stir at a constant temperature for more than 2 hours until fully mixed to obtain the first solution.

[0056] S102: Add 1%-5% zinc oxide and 2%-5% silver powder to the first solution and stir for 6-8 hours until fully mixed and dispersed to obtain the second solution;

[0057] S103: Add 30%-50% calcium acetate to the second solution and stir at 80-90℃ for 12-16 hours to obtain temporary composite cationic particles;

[0058] S104: The temporary composite cationic particles are dried at 40-60℃ for 36-72 hours to obtain the final composite cationic particles.

[0059] S105: By weight percentage, 0.01%-0.1% silver powder, 60%-80% EVA resin, 1% alkyl polyether, 5%-20% calcium acetate, 5%-10% aromatherapy essential oil, and 5%-10% of the final composite cationic particles are stirred and mixed for 2-4 hours, and then mixed using a screw granulator to produce masterbatch, yielding a semi-finished product.

[0060] S106: The semi-finished product is subjected to extrusion or injection molding processes, and then formed in conjunction with a filter element mold to obtain the filter element.

[0061] This preparation method does not require advanced equipment or complex processes, has low production costs, simple operation, and high production efficiency. In this embodiment, the method enables the formation of a porous structure within the aromatherapy scale-inhibiting and antibacterial filter element. The porous structure design can control the extremely slow dissolution of ppb-level cations adsorbed on the material surface into water, thereby achieving highly efficient and long-lasting antibacterial and antimicrobial effects, improving the service life of the filter element, and reducing replacement costs.

[0062] In this embodiment, after adding 30%-50% calcium acetate to the second solution and stirring at 80-90°C for 12-16 hours, composite cationic particles with a size of 0.5mm-1mm (i.e., temporary composite cationic particles) are obtained. To ensure that the composite cationic particles are completely dehydrated and maintain their intact shape, the temporary composite cationic particles need to be dried to obtain dried composite cationic particles (i.e., final composite cationic particles). To prevent the composite cationic particles from cracking or deforming, this embodiment adopts a method of slowly drying the temporary composite cationic particles for 36-72 hours during a gradual cooling process to obtain the final composite cationic particles. The temperature of the entire gradual cooling process is always controlled between 40-60°C.

[0063] In this embodiment, the scale-inhibiting and antibacterial filter element is composed of 80%-90% plastic and 10%-20% composite silver ion particles.

[0064] The specific manufacturing method is as follows: 80%-90% of plastic and 10%-20% of composite silver ion particles are mixed, and then the mixture is directly mixed and sintered at a high temperature of 150-200 degrees Celsius using a mold to obtain a scale-inhibiting and antibacterial filter element.

[0065] In this embodiment, the antibacterial function of the scale-inhibiting and antibacterial filter element was tested. Specifically, the filter element was placed inside an angle valve and connected to a water pipe. After quickly rinsing with 0.1 tons, 10 tons, 15 tons, and 20 tons of water, samples were taken from the rinsed water, and fixed amounts of various bacteria were added. The antibacterial effect of the water was tested after 120 minutes. The above operation was repeated three times to obtain three sets of test samples of 0.1 tons, 10 tons, 15 tons, and 20 tons of water. The results of treating E. coli with the original water sample and the water sample flowing through the scale-inhibiting and antibacterial filter element were compared. For the 0.1-ton sample, the results of treating Candida albicans with the original water sample and the water sample flowing through the scale-inhibiting and antibacterial filter element were also compared. The comparison results are shown in Table 1.

[0066] Table 1

[0067]

[0068]

[0069] As shown in Table 1, the water treated by the scale-inhibiting and antibacterial filter cartridge has a good antibacterial effect; at the same time, the silver ion content in the water is less than 0.03 mg / L, which meets the drinking water standards and is safe for human consumption.

[0070] Please see Figure 10 The two cups contain water with the same scale. The right image shows the scale removal effect after 24 hours after adding composite cationic particles containing large particles. As can be seen, its scale removal effect is obvious. The composite cationic particles used in the scale-inhibiting and antibacterial filter cartridge are a smaller version of the composite cationic particles shown in the image. The composite cationic particles used in this embodiment have a diameter of 0.5mm-1mm, which can be better embedded in the filter cartridge material.

[0071] In this embodiment, the aromatherapy filter element is composed of 0.01%-0.1% silver powder, 60%-80% EVA resin, 1% alkyl polyether, 10%-30% calcium acetate, and 5%-10% aromatherapy essential oil.

[0072] The specific manufacturing method is as follows: 0.01%-0.1% silver powder, 60%-80% EVA resin, 1% alkyl polyether, 10%-30% calcium acetate, and 5%-10% aromatherapy essential oil are mixed to form a mixture; then, the mixture is heated to a molten state through an extruder, and then the molten mixture is extruded through a mold to form the inner core 5 of the aromatherapy filter cartridge; during the extrusion molding process, the temperature and pressure of the extruder need to be controlled to ensure that the size and shape of the inner core 5 of the aromatherapy filter cartridge meet the requirements; at the same time, the extruded aromatherapy filter cartridge also needs to be cooled to prevent deformation or damage; then, the inner core 5 of the aromatherapy filter cartridge and the outer shell material are placed together in a heat sealing machine and heat-sealed under high temperature and high pressure; then, the heat-sealed aromatherapy filter cartridge is cooled to obtain the finished aromatherapy filter cartridge, wherein the outer shell material can be plastic, stainless steel, etc.

[0073] The aromatherapy filter cartridge and aromatherapy scale-inhibiting and antibacterial filter cartridge of this embodiment solve the problems of current bath aromatherapy which mainly dissolve in the bathtub, are added to the water at once, require bathtub soaking for use, have limited applicable scenarios, and the fact that aromatherapy essential oils in conventional filter cartridge materials are extremely easy to evaporate quickly or be released rapidly with the water flow, making it difficult to meet the needs of long-lasting water aromatherapy. The aromatherapy filter cartridge and aromatherapy scale-inhibiting and antibacterial filter cartridge of this embodiment combine aromatherapy essential oils with silver ions and EVA resin, and by controlling the corresponding ratio and preparation process, achieves efficient locking of aromatherapy essential oils, forming a slow release effect, which can achieve stable fragrance release for 3-6 months. Therefore, the water sprayed from the shower head can also have fragrance for a long time, and it is highly convenient to use.

[0074] The scale-inhibiting and antibacterial filter cartridges and aromatherapy scale-inhibiting and antibacterial filter cartridges in this embodiment are actually microporous structures, which can easily allow water molecules to pass through. The composite cation particles have a stable and uniform structure in the filter cartridge, which can prevent leakage and promote the stable release of low-concentration silver ions and various slow-release cations. ppb-level silver ions can be detected in the water passing through the showerhead, which meets drinking-grade standards and can effectively inhibit bacteria. The low-concentration silver ions and various slow-release cations can provide a certain degree of antibacterial effect on the human body surface after showering and washing hair, reducing bacterial infections and skin problems. At the same time, the water with antibacterial function remaining in the showerhead can also inhibit the growth of bacteria in the showerhead. The water remaining in the bathroom can effectively inhibit the reproduction of common bacteria and keep the bathroom clean.

[0075] Please see Figure 9 In this embodiment, the filter element 3 is provided with a buckle structure at both ends, a through hole 8 on the buckle structure, and an anti-slip device 9 on the buckle structure.

[0076] Specifically, the buckle structure is divided into an upper buckle 10 and a lower buckle 11. The upper buckle 10 and the lower buckle 11 are detachably connected to both ends of the filter element 3. The anti-slip device 9 is sleeved on the upper buckle 10. The upper buckle 10 has a general structure for fixing the filter element 3 and the anti-slip device 9, and also has a structure for connecting the shower head 1. The lower buckle 11 is mainly used to fix the lower end and support the inner core 5. The through hole 8 is mainly used for water to enter the interior from the outside of the filter element 3, carrying low concentrations of silver ions, complex cations and aromatherapy scents, and spraying out through the shower head. The anti-slip device 9 is mainly used to achieve a stable connection between the filter element 3 and the inner interface of the shower head, prevent water leakage, and ensure that the filter element 3 does not fall off. The anti-slip device 9 is generally made of anti-slip rubber ring.

[0077] In this embodiment, the shape of the filter element 3 can be designed according to the requirements. For example, in order to increase the contact area with the water and thus improve the antibacterial and bacteriostatic effect of the water, the outer surface of the filter element 3 can be set as a spiral shape, or the filter element 3 can be set as a pleated filter element. The pleated filter element has a large filtration area and a large flow rate, and is suitable for high flow rate filtration.

[0078] In this embodiment, the internal structure of the filter element 3 can be designed according to requirements. For example, in order to increase the contact area with the water and thus improve the antibacterial and bacteriostatic effect of the water, the internal structure of the filter element 3 can be set as a snowflake structure, or other structures can be used to achieve the corresponding effect.

[0079] In this embodiment, the bottom of the handle 2 is also provided with a connection port 12 for connecting to a water pipe (e.g., ...). Figure 2 As shown), the water pipe inputs water into the water outlet channel through the connection port 12, and after being filtered by the filter element 3, it is discharged through the water outlet.

[0080] In this embodiment, the water outlet on the nozzle 1 is divided into a silicone massage water outlet 13 and a center water outlet 14 (e.g., Figure 2 As shown), the silicone massage water outlet 13 is equipped with several silicone particles. The silicone massage water outlet 13 can directly massage the scalp through the silicone particles. While washing the hair, it can relieve some minor skin problems through silver ions and complex cations. At the same time, the aromatherapy essential oil components slowly released in the water can also help relieve stress, leaving the hair with an aromatherapy scent and moisturized.

[0081] Furthermore, the silicone massage water outlet 13 is arranged in a ring around the central water outlet 14. Since the aperture of the silicone massage water outlet 13 is smaller than that of the central water outlet 14, the water output of the silicone massage water outlet 13 is less than that of the central water outlet 14. However, the arrangement of the silicone massage water outlet 13 in a ring around the central water outlet 14 allows the silicone particles on the silicone massage water outlet 13 to simultaneously achieve close contact between the water output from the central water outlet 14 and the water output from the silicone massage water outlet 13 and the human head, thereby enhancing the antibacterial and bacteriostatic effect of the filter element 3.

Similar or identical parts between embodiments can be referred to interchangeably. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.
