Description

Technical Field

[0001] This utility model relates to the field of water dispenser technology, and more specifically, to a multi-stage filtration structure and a water dispenser thereof. Background Technology

[0002] A water dispenser is a common household and commercial appliance, primarily used to provide hot and cold water to meet people's drinking needs. It typically consists of a water tank, heating and cooling systems, a water outlet, and a control panel. The dispenser has a built-in heating element that heats the water to a set temperature, usually 85-95 degrees Celsius, suitable for making tea, coffee, etc. Water dispensers generally use bottled water as their source. To ensure cleaner and safer drinking water, users utilize the dispenser's filter cartridge for multi-stage filtration. The filter cartridge's main function is to remove impurities, pollutants, and harmful substances from the water using physical methods, improving water quality and ensuring drinking water safety. Since the filtration efficiency and performance of the filter cartridge decrease after a period of use, it is necessary to replace the filter cartridge.

[0003] In related technologies, during the use of filter cartridges, the filter cartridge and filter element are generally installed, disassembled and replaced using a threaded method, so that the filter element with reduced filtration performance and efficiency can be replaced and put into use.

[0004] However, in the current use of filter cartridges, due to the threaded installation and disassembly method, only the filter element as a whole can be replaced, while the filter media inside the filter element is difficult to replace. Frequent replacement of the filter element increases the cost of use, and different usage needs have different requirements for the filter media in the filter element, making it difficult to replace the filter element separately, which affects the flexibility of filter element replacement and filtration adaptability.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4 This utility model provides a technical solution: a multi-stage filtration structure and its water dispenser, including a water receiving tank 1 and a multi-stage filtration mechanism. A filter tank 2 is installed on the top of the water receiving tank 1, and a top cover 3 is installed on the top of the filter tank 2. The filter tank 2 can perform multi-stage filtration of the water inside the filter tank 2. During filtration, it is convenient for the user to replace the filter media 8 inside the filter cartridge 6 and filter frame 7 according to the actual needs of the user. This avoids the situation where it is difficult to adapt the filter tank 2 during use, thus improving the flexibility and adaptability of the filter tank 2 in terms of filtration replacement.

[0031] Reference Figures 1-4 In a preferred embodiment, the multi-stage filtration mechanism includes a filter port 4 located at the top of the water receiving tank 1. A filter head 5 is fixedly connected to the bottom of the water receiving tank 2, located inside the filter port 4. A filter cylinder 6 is movably connected to the bottom of the filter head 5. A filter frame 7 is movably connected inside the filter cylinder 6, and the filter frame 7 is filled with filter media 8. A filter ring 9 is fixedly connected to the outer side of the bottom of the filter frame 7. A filter media replacement mechanism is located on the right side of the filter cylinder 6. When water from the water receiving tank 2 enters the filter cylinder 6 through the filter port 4 and filter head 5, the filter frame 7, in conjunction with the filter media 8, filters the water. Because the filter frame 7 is arranged in multiple layers and is made of microporous ceramic, it effectively removes bacteria and suspended solids from the water by utilizing the tiny pores on its surface. Simultaneously, the filter media 8 filled from top to bottom of the filter frame 7 consists of mineralized red spheres and softened resin, respectively. The filter cartridge 6 contains grease, mineralized white balls, and coconut shell charcoal. When water enters the cartridge 6, the filter frame 7, in conjunction with the internally filled filter media 8, performs layer-by-layer filtration. After filtration, the cartridge 6 is separated from the filter head 5, and the filter frame 7 is also separated from the cartridge 6, allowing for the replacement of the cartridge 6 and filter media 8. The filter media replacement mechanism includes a replacement port 10, a rubber head 11, and a replacement seat 12. The replacement port 10 is located on the right side of the cartridge 6, the rubber head 11 is movably connected inside the replacement port 10, and the replacement seat 12 is fixedly connected to the right side of the rubber head 11. This provides users with space to replace the filter media 8 inside the cartridge 6 and filter frame 7, and seals the cartridge 6 after the filter media 8 is replaced. This prevents the filter media 8 from being difficult to replace during use, thus improving the convenience of replacing the filter media 8 and the sealing effect of the cartridge 6.

[0032] Reference Figures 2-4 In a preferred embodiment, a fixing frame 13 located outside the material changing seat 12 is fixedly connected to the top and bottom of both sides of the filter cartridge 6. A fixing head 14 located inside the fixing frame 13 is movably connected to the top and bottom of both sides of the material changing seat 12. This allows for the closed positioning of the material changing seat 12 and the filter cartridge 6, avoiding difficulties in closing and positioning the material changing seat 12 during use. This improves the ease of closing and positioning the material changing seat 12. A lifting port 15 is provided on the inner side of the fixing head 14. A lifting bar 16 is movably connected inside the lifting port 15. The inner side of the lifting bar 16 is fixedly connected to the outer side of the material changing seat 12. This allows for the lifting connection between the fixing head 14 and the material changing seat 12 to prevent deviation, thus improving the connection effect between the fixing head 14 and the material changing seat 12.

[0033] Reference Figures 2-4 In a preferred embodiment, by movably connecting translation frames 17 to both sides of the material changing seat 12, with the left side of the translation frame 17 fixedly connected to the right side of the fixed head 14, it is possible to provide force application for synchronously moving the fixed heads 14 on both sides of the material changing seat 12, thus improving the ease of raising and lowering the fixed head 14. The bottom of the inner wall of the filter head 5 and the filter cylinder 6 are both provided with screw grooves 18, and the screw grooves 18 are internally threaded with screw rings 19. The bottom of the screw rings 19 is fixedly connected to the top of the filter cylinder 6 and the filter ring 9 respectively, which can provide the filter cylinder 6 and the filter ring 9 with the medium that can be inserted and connected to the filter head 5 and the filter cylinder 6 respectively, thus improving the ease of disassembly and installation of the filter cylinder 6 and the filter ring 9.

[0034] Reference Figures 2-3 In a preferred embodiment, by movably connecting sealing rings 20 to the top of both the filter ring 9 and the filter cartridge 6, with the top of the sealing rings 20 contacting the bottom of the filter head 5 and the filter cartridge 6 respectively, the filter cartridge 6 and the filter ring 9 can be sealed after installation, thus improving the installation sealing performance of the filter cartridge 6 and the filter ring 9.

[0035] A water dispenser includes a multi-stage filtration structure.

[0036] Specifically, the working process or principle of this multi-stage filtration structure and its water dispenser is as follows: During use, the filter cartridge 6 is held and rotated to separate the screw ring 19 from the screw groove 18 inside the filter head 5, allowing for disassembly of the filter cartridge 6 and filter head 5. Then, a new filter cartridge 6 is held and aligned with the screw ring 19 at the bottom of the filter head 5, and the filter cartridge 6 is rotated to connect the screw ring 19 to the screw groove 18. At this time, the sealing ring 20 moves with the filter cartridge 6 and contacts the bottom of the filter head 5, sealing the connection between the filter cartridge 6 and filter head 5. This allows for the installation and replacement of the new filter cartridge 6 and filter head 5. When the water inside the water tank 2 enters the filter cartridge 6 through the filter head 5, the filter frame 7 is arranged in multiple layers and is made of microporous ceramic. The filter frame 7 utilizes tiny pores on its surface to effectively remove bacteria and suspended solids from the water. Simultaneously, the filter media 8 filled from top to bottom of the filter frame 7 consists of mineralized red balls, softening resin, mineralized white balls, and coconut shell charcoal. Due to the fine surface of the mineralized red balls, they effectively adsorb harmful substances and impurities in the water. These mineralized red balls are made from natural minerals rich in beneficial trace elements such as zinc, iron, and selenium. When hard water flows through the resin particles, the calcium and magnesium ions in the water exchange with the sodium ions on the resin. The resin adsorbs hard ions and releases an equal amount of sodium ions, thus reducing water hardness. The mineralized white balls are a composite material of natural materials and minerals, possessing specific mineralizing functions. The mineralized white balls also inhibit bacterial growth. The coconut shell charcoal effectively improves water quality, possessing excellent adsorption properties to remove chlorine, odors, and impurities from the water. Through layer-by-layer filtration by the filter media 8 inside the filter cartridge 6 and filter frame 7, the safety of drinking water is ensured. Then, by holding and rotating the replaced filter cartridge 6 and filter ring 9, the screw ring 19 at the top of the filter ring 9 separates from the screw groove 18 at the bottom of the filter cartridge 6. The filter ring 9 then moves the filter frame 7 out of the filter cartridge 6, carrying out the used filter media 8. After all the filter media 8 has been discharged from the filter cartridge 6, the filter cartridge 6, filter frame 7, and filter ring 9 are cleaned by brushing. After the filter cartridge 6 is cleaned and dried, the filter ring 9 is held and the filter frame 7 is inserted into the filter cartridge 6. The screw ring 19 is then rotated by the filter ring 9 into the screw groove 18 inside the filter cartridge 6, causing the screw ring 19 to separate from the screw groove 18 at the bottom of the filter cartridge 6. 9. The filter frame 7 and filter cartridge 6 are connected by threaded installation using the filter ring 9. At this time, the sealing ring 20 moves with the filter ring 9 and contacts the bottom of the filter cartridge 6, sealing the connection between the filter ring 9 and the filter cartridge 6. Then, different filter media 8 are filled into different interval spaces inside the filter frame 7 through the material exchange port 10, preparing for the subsequent installation and reuse of the filter element. The added filter media 8 can be selected and replaced according to actual usage needs. It should be noted that the filter media 8 filled inside the filter frame 7 and filter cartridge 6 must meet the safety requirements for drinking water filtration. After the filter media 8 is filled, the hand-held material exchange base 12 drives the rubber head 11 into the material exchange port 10 to close the material exchange port 10. At this time, the fixing head 14 moves with the material exchange base 12 and aligns with the fixing frame 13.Then, the translation frame 17 synchronously moves the fixed head 14 downwards into the fixed frame 13, performing insertion and positioning between the closed material changing seat 12 and the filter cartridge 6. At this time, the lifting bar 16 moves inside the lifting port 15, performing lifting and translational connection between the fixed head 14 and the material changing seat 12 during the movement, ensuring the closing effect of the filter cartridge 6 after filling with filter media 8, and preparing for subsequent replacement.
