Description

Technical Field

[0001] This utility model is a detachable water purifier, belonging to the field of water purifiers. Background Technology

[0002] With the improvement of residents' living standards and the enhancement of health awareness, drinking water safety has become one of the core issues of public concern. As a key device to ensure the quality of drinking water in the home, water purifiers have seen a continuous increase in market demand. At present, the mainstream water purifier products on the market are mainly divided into countertop, under-sink, and wall-mounted types. Their core functions all rely on filter cartridges to intercept and purify harmful substances such as impurities, heavy metals, and microorganisms in the raw water to meet the different needs of families for direct drinking water and domestic water. Among them, six-stage filtration water purifiers with more comprehensive purification capabilities have gradually become a popular choice in the mid-to-high-end market because they can cover the entire process from coarse filtration to deep mineralization. However, there are still many technical pain points that need to be solved in the actual application of such products.

[0003] Firstly, in terms of filter maintenance and replacement, traditional water purifiers mostly adopt an integrated sealed design, with a complex connection structure between the filter and the main body of the device. This often requires professionals to use specialized tools to complete disassembly and installation. Especially for six-stage filtration water purifiers, the traditional design requires separate pipe connections at both ends of each filter. Furthermore, the pipe specifications and interface directions for different filter types are not significantly different, lacking clear compatibility markings and guidance structures. Users are very likely to make mistakes when replacing or repairing the filters themselves, which can not only interrupt the purification process but also cause substandard water to directly enter subsequent filter cartridges, resulting in excessive wear of the filter cartridges, significantly shortening their lifespan, and even causing abnormal internal pressure, increasing the safety risks of leaks and pipe bursts. Therefore, designing a detachable water purifier is essential. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a detachable water purifier to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a detachable water purifier, comprising: The cabinet is vertically divided into a control section and a water purification section with an opening at the top, and the water purification section is horizontally equipped with partitions.

Locking holes are provided on the locking plate at positions corresponding to the two locking blocks, and the shape of the locking holes is adapted to the locking blocks.

[0009] Furthermore, a wrench is provided at the center of one end of the adjusting member, and the bottom of the adjusting member away from the wrench is designed with a rounded transition. The adjusting member can rotate between 0° and 90°, and when the adjusting member is horizontal, the locking block is inserted into the locking hole under the action of the compression spring.

[0010] Furthermore, the top of the mounting sleeve is rotatably connected to a threaded fastening sleeve, and the bottom of the inside of the mounting sleeve is provided with a sealing connection plug. The bottom of each filter element is provided with an insertion hole that matches the sealing connection plug, and the top of the outer surface of the filter element is provided with a threaded part that matches the threaded fastening sleeve.

[0011] Furthermore, the six filter elements are a PP cotton filter element, a granular activated carbon filter element, a compressed activated carbon filter element, an RO reverse osmosis membrane filter element, a post-activated carbon filter element, and a metasilicic acid mineralization filter element. The PP cotton filter element and the granular activated carbon filter element are located on both sides of the water purification section away from the control section. The post-activated carbon filter element and the metasilicic acid mineralization filter element are located on both sides of the water purification section near the control section. The compressed activated carbon filter element is located in the water purification section between the granular activated carbon filter element and the metasilicic acid mineralization filter element. The RO reverse osmosis membrane filter element is located in the water purification section between the PP cotton filter element and the post-activated carbon filter element. The tops of the PP cotton filter element and the granular activated carbon filter element, the compressed activated carbon filter element and the RO reverse osmosis membrane filter element, and the post-activated carbon filter element and the metasilicic acid mineralization filter element are all connected by detachable conduits. The six mounting sleeves correspond one-to-one with and are adapted to the six filter elements.

[0012] Furthermore, the water pipe assembly includes an inlet pipe, a first water pipe, a second water pipe, a secondary purified water pipe, and a direct drinking water pipe. The inlet pipe has an "L"-shaped design, and the top of the vertical section of the inlet pipe is connected to a sealed connector plug for the PP cotton filter element. The horizontal section of the inlet pipe extends away from the control unit and penetrates the outer wall of the casing. Both the first and second water pipes have a "U"-shaped design. The two ends of the first water pipe are respectively connected to the sealed connector plugs for the granular activated carbon filter element and the compressed activated carbon filter element. The two ends of the second water pipe are respectively connected to the RO reverse osmosis membrane filter element and the downstream filter element. The activated carbon filter cartridge is connected to a sealed connector plug. The bottom of the post-activated carbon filter cartridge is also provided with a waste discharge port. The installation sleeve corresponding to the post-activated carbon filter cartridge is provided with a sealed connector plug corresponding to the waste discharge port. The bottom of this sealed connector plug is connected to a secondary purified water pipe, which extends away from the control unit and penetrates the outer wall of the box. The drinking water pipe is designed in an "L" shape, and the top of the vertical pipe of the drinking water pipe is connected to the sealed connector plug connected to the metasilicic acid mineralization filter cartridge.

[0013] The beneficial effects of this utility model are: 1. This application adopts an "installation sleeve + filter element" adapter design, with six filter elements corresponding one-to-one with six installation sleeves. The installation process only requires two steps: First, insert the filter element directly into the corresponding installation sleeve, and quickly achieve bottom sealing and water circuit connection through the sealing connector inside the sleeve; Second, rotate the threaded fastening sleeve at the top of the installation sleeve, and use its adapter structure with the threaded part at the top of the outer surface of the filter element to further lock and fix the filter element and the installation sleeve. This design simplifies the operation and avoids the loosening problem that may occur in traditional plug-in connections through the locking effect of the threaded fastening sleeve, ensuring a tight and stable connection between the filter element and the installation sleeve, and taking into account both ease of operation and connection reliability.

[0014] 2. Addressing the critical issue of traditional six-stage water purifiers where "each filter element requires separate pipe connections at both ends, leading to easy misconnections due to similar interfaces," this application employs a dual error-proof design. It achieves end-to-end error prevention by eliminating the need for manual connection at the bottom and simplifying connection at the top. Firstly, the filter elements and mounting sleeves use a one-to-one matching structure. After inserting different types of filter elements into their dedicated mounting sleeves, the bottom of the filter element automatically completes water flow through the sealed connector built into the sleeve. This eliminates the need for manual connection of the bottom pipes, avoiding potential misconnections. Secondly, the top pipe connection uses a "two-to-two connection + three parallel pipes" layout. There's no need to distinguish complex interface directions and specifications; users simply connect the top pipes of the corresponding filter element group. This design completely eliminates the possibility of misconnection, preventing interruptions in the purification process, excessive filter element wear, and the risk of leaks and pipe bursts caused by abnormal internal pressure. This comprehensively ensures both purification effectiveness and operational safety. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please see Figures 1 to 6 This utility model provides a technical solution: a detachable water purifier, including a housing 1. The interior of the housing 1 is vertically divided into a control section and a water purification section with an open top. A partition 10 is horizontally arranged inside the water purification section. A groove 101 is opened at the center of the top of the control section of the housing 1. A locking component 4 is installed in the groove 101. A slot 103 is provided in the housing 1 below the groove 101. The end of the slot 103 near the water purification section is open. A top cover 3 is horizontally arranged at the top of the water purification section and is slidably connected to the housing 1.

All six mounting sleeves 6 are fixed to the top of the partition 10, and a filter element 7 and a water guide pipe assembly 9 are inserted into each mounting sleeve 6. Inside the lower housing 1, the water pipe assembly 9 is used to connect to an external water source, connect to the filter element 7, and discharge secondary purified water and direct drinking water. This divides the housing 1 into an independent control section and a water purification section, achieving functional zoning, avoiding mutual interference between control components and water circuit components, and improving the stability of equipment operation. The partition 10 provides stable support for the mounting sleeve 6 and separates the mounting sleeve 6 from the water pipe assembly 9, facilitating separate maintenance. The top cover 3 is slidably connected to the housing 1. With the matching of the locking insert 5 and the slot 103, it is convenient to quickly open the water purification section for maintenance of the filter element 7, and the locking component 4 ensures the sealing of the top cover 3 after it is closed, preventing dust and impurities from entering. The six mounting sleeves 6 are distributed in a matrix, making reasonable use of the space in the water purification section, while providing a dedicated installation position for the filter element 7, avoiding the pipeline chaos caused by the haphazard placement of the filter element 7.

[0018] Furthermore, a touch panel 2 is provided at one end of the housing 1 near the control unit, and a control chip 8 is provided inside the control unit. The touch panel 2, together with the control chip 8, enables visual operation and intelligent control of the equipment's operating status. Users can intuitively view information such as the filter cartridge 7's lifespan, water quality, and water output mode through the touch panel 2, and can grasp the operating status without disassembling the housing 1.

[0019] Furthermore, slide rails 102 are provided on both sides of the top of the water purification section of the cabinet 1, and sliding grooves 302 adapted to the slide rails 102 are provided on both sides of the top cover 3. A downwardly bent anti-detachment side plate 301 is integrally provided at the end of the top cover 3 near the control part, and a locking plate 5 is integrally provided at the center of the end of the anti-detachment side plate 301 near the control part. The matching design of the slide rails 102 and the sliding grooves 302 makes the opening and closing of the top cover 3 smoother, avoiding the problem of easy jamming and damage of the traditional snap-on top cover 3, and extending the service life of the top cover 3. The bending structure of the anti-detachment side plate 301 can limit the displacement range of the top cover 3 during the sliding process, preventing the top cover 3 from completely detaching from the cabinet 1 and causing loss or damage. The integrated design of the locking plate 5 and the anti-detachment side plate 301 improves the overall structure, prevents the locking plate 5 from loosening due to frequent insertion and removal, ensures the stability of the top cover 3 after locking, and ensures that the locking plate 5 can be accurately inserted into the slot 103.

[0020] Furthermore, the locking assembly 4 includes an adjusting member 401, a central post 402, a mounting base 403, a compression spring 404, and a locking block 405. Mounting bases 403 are provided on both sides of the bottom of the adjusting member 401, and locking blocks 405 with matching shapes are provided inside the mounting bases 403. The central post 402 is fixed to the top of the locking block 405, and the top of the central post 402 extends vertically upward through the mounting base 403. The compression spring 404 is connected to the top of the locking block 405, and the top of the compression spring 404 is connected to the top end inside the mounting base 403. The compression spring 404 surrounds the central post 402. Hinge grooves 4012 are provided on both sides inside the adjusting member 401, and the top of the central post 402 extends into the hinge grooves 4012 and hinges with the adjusting member 401. The locking plate 5 is positioned corresponding to the positions of the two locking blocks 405. Each part is provided with a locking hole 501, and the shape of the locking hole 501 is adapted to the locking block 405. The locking component 4 automatically pushes the locking block 405 into the locking hole 501 of the locking plate 5 by the elastic force of the compression spring 404, realizing the automatic locking of the top cover 3 without the need to manually tighten the screws, making the operation more convenient. The hinge structure of the hinge groove 4012 of the central column 402 and the adjusting component 401, together with the elastic action of the compression spring 404, can easily control the lifting and lowering of the locking block 405 by rotating the adjusting component 401, thereby quickly unlocking the top cover 3 and solving the problem of cumbersome unlocking of traditional locking structures. The two locking blocks 405 are symmetrically arranged in the mounting base 403 and are precisely adapted to the locking hole 501 of the locking plate 5, ensuring that the top cover 3 is evenly stressed when locked, avoiding the problem of the top cover 3 tilting and poor sealing caused by locking on one side.

[0021] Furthermore, a wrench 4011 is provided at the center of one end of the adjusting member 401, and the bottom of the adjusting member 401 away from the wrench 4011 is designed with a rounded transition. The adjusting member 401 can rotate between 0° and 90°. When the adjusting member 401 is horizontal, the locking block 405 is inserted into the locking hole 501 under the elastic force of the compression spring 404. The wrench 4011 is designed to provide a force point for rotating the adjusting member 401. Users can easily rotate the adjusting member 401 manually to lock / unlock without the need for tools, further reducing the operation threshold. The rounded transition design of the adjusting member 401 away from the wrench 4011 makes the rotation of the adjusting member 401 smoother.

[0022] Furthermore, a threaded fastening sleeve 601 is rotatably connected to the top of the mounting sleeve 6, and a sealing connector 602 is provided at the bottom inside the mounting sleeve 6. Each filter element 7 has an insertion hole at its bottom that matches the sealing connector 602, and a threaded portion 701 matching the threaded fastening sleeve 601 is provided at the top of the outer surface of the filter element 7. The sealing connector 602 at the bottom of the mounting sleeve 6 matches the insertion hole at the bottom of the filter element 7, allowing the filter element 7 to automatically complete the bottom water channel sealing and connection after being inserted into the mounting sleeve 6, eliminating the need for manual pipe connection. To avoid the risk of incorrect pipe connections, the threaded connection between the threaded fastening sleeve 601 and the threaded portion 701 on the top of the outer surface of the filter element 7 firmly fixes the filter element 7 inside the mounting sleeve 6, preventing the filter element 7 from loosening or shifting due to water flow impact during equipment operation. At the same time, it further enhances the sealing performance between the sealing connector 602 and the insertion hole of the filter element 7, preventing water leakage. The threaded connection structure is easy to operate. Users only need to rotate the threaded fastening sleeve 601 on the top of the mounting sleeve 6 to fix or remove the filter element 7 without professional tools, improving the convenience of filter element 7 replacement.

[0023] Furthermore, the six filter cartridges 7 are respectively a PP cotton filter cartridge, a granular activated carbon filter cartridge, a compressed activated carbon filter cartridge, an RO reverse osmosis membrane filter cartridge, a post-activated carbon filter cartridge, and a metasilicic acid mineralization filter cartridge. The PP cotton filter cartridge and the granular activated carbon filter cartridge are located on both sides of the water purification section away from the control section. The post-activated carbon filter cartridge and the metasilicic acid mineralization filter cartridge are located on both sides of the water purification section closer to the control section. The compressed activated carbon filter cartridge is located in the water purification section between the granular activated carbon filter cartridge and the metasilicic acid mineralization filter cartridge. The RO reverse osmosis membrane filter cartridge is located in the water purification section between the PP cotton filter cartridge and the post-activated carbon filter cartridge. The tops of the PP cotton filter cartridge, the granular activated carbon filter cartridge, the compressed activated carbon filter cartridge, the RO reverse osmosis membrane filter cartridge, the post-activated carbon filter cartridge, and the metasilicic acid mineralization filter cartridge are all connected by detachable conduits. The system features six mounting sleeves 6 that correspond one-to-one with six filter cartridges 7. The combination of six different filter cartridges 7 covers the entire purification process, from coarse filtration, adsorption, deep purification to mineralization. It effectively removes impurities, heavy metals, and odors from the raw water while increasing beneficial minerals, improving taste and health value. The filter cartridges 7 are arranged in a specific order within the purification section, connected in pairs via a detachable top conduit, forming a scientific purification process. This ensures that the raw water is thoroughly purified by passing through each filter cartridge 7 sequentially, preventing incomplete purification. The one-to-one correspondence between the six mounting sleeves 6 and the six filter cartridges 7 physically eliminates the possibility of incorrect installation. Combined with the simplified connection of the top conduit, this completely solves the problem of easy misconnection of pipes in traditional six-stage water purifiers, reducing the difficulty of user operation.

[0024] Furthermore, the water pipe assembly 9 includes an inlet pipe 901, a first water pipe 902, a second water pipe 903, a secondary purified water pipe 904, and a direct drinking water pipe 905. The inlet pipe 901 has an "L"-shaped design, and the top of the vertical pipe of the inlet pipe 901 is connected to the sealing connector 602 that connects to the PP cotton filter element. The horizontal pipe of the inlet pipe 901 extends to the end away from the control unit and penetrates the outer wall of the housing 1. The first water pipe 902 and the second water pipe 903 are both "U"-shaped designs. The two ends of the first water pipe 902 are respectively connected to the sealing connectors that connect to the granular activated carbon filter element and the compressed activated carbon filter element. Connector 602, the two ends of the second water pipe 903 are respectively connected to the sealing connector 602 of the RO reverse osmosis membrane filter and the post-activated carbon filter. The post-activated carbon filter also has a waste discharge port at the bottom. The corresponding sealing connector 602 is provided in the mounting sleeve 6 of the post-activated carbon filter. The bottom of this sealing connector 602 is connected to the secondary purified water pipe 904, and the secondary purified water pipe 904 extends away from the control unit and penetrates the outer wall of the box 1. The drinking water pipe 905 has an "L" shape design, and the top of the vertical pipe of the drinking water pipe 905 is connected to the metasilicic acid The mineralized filter element is connected to the sealed connector 602. The horizontal tube of the drinking water pipe 905 extends away from the control unit and penetrates the outer wall of the housing 1. The "L"-shaped inlet pipe 901 and the "L"-shaped drinking water pipe 905 design can make reasonable use of the internal space of the housing 1, and at the same time facilitate the connection between the inlet pipe 901 and the external water source, and between the drinking water pipe 905 and the external water supply. The "U"-shaped first water guide pipe 902 and the "U"-shaped second water guide pipe 903 can flexibly adapt to the water circuit connection of granular activated carbon filter element, compressed activated carbon filter element, RO reverse osmosis membrane filter element, and post-activated carbon filter element to ensure water flow. The secondary purified water pipe 904 and the direct drinking water pipe 905 are set up separately, so that the secondary purified water can be used for domestic water and direct drinking water independently, which can meet the diverse water needs of families, avoid the waste of high-quality direct drinking water in non-drinking scenarios, and improve the utilization rate of water resources. The inlet pipe 901, the first water guide pipe 902, the second water guide pipe 903, the secondary purified water pipe 904, and the direct drinking water pipe 905 are all directly connected to the sealing connection plug 602 of the corresponding filter element 7, without the need for manual assembly of the pipeline, further simplifying the equipment installation and maintenance process, while ensuring the sealing and stability of the water connection.
