Description

Technical Field

[0001] This utility model relates to the field of water purifier technology, and in particular to a water purifier with convenient filter replacement. Background Technology

[0002] A water purifier, also called a water purification machine or water quality purifier, is a water treatment device that deeply filters and purifies water according to usage requirements. Water purifiers use tap water as the input and filter it through different filter cartridges to obtain drinking water. The drinking water from a water purifier reaches the pure water level and can be consumed directly. Water purifiers on the market generally filter domestic water through multiple filter cartridges, such as PP cotton filters, activated carbon filters, ultrafiltration membrane filters, reverse osmosis membrane filters, or composite filters with equivalent functions. Debris trapped in the filter cartridges accumulates inside, requiring regular manual cleaning to ensure proper machine operation. Water purifiers use removable filter cartridges for easy replacement; however, the locking mechanisms of removable filter cartridges in current market are complex, prone to jamming and failure, increasing maintenance costs and reducing lifespan.

[0003] For example, Chinese Patent Publication No. CN113354117A, published on September 7, 2021, entitled "A Water Purifier with Quick Filter Replacement," includes three filter cartridge housing structures, a water pump, an integrated water circuit board assembly, and a filter cartridge main body structure including a base, a filter cartridge retainer, a filter cartridge, two filter cartridge stop valve assemblies, a button rod, a filter cartridge retainer sliding plate, and two filter cartridge retainer stop valve assemblies. The filter cartridge main body structure is horizontally oriented. The filter cartridge includes one filter cartridge body and two filter cartridge cylinders, with a composite filter cartridge and an activated carbon filter cartridge installed in the two filter cartridge cylinders respectively. The filter cartridge retainer includes one filter cartridge retainer body and two filter cartridge retainer cylinders, and the base includes one base body and two base retainer cylinders. A filter cartridge stop valve assembly is provided in the inner cavity of the filter cartridge cylinder, and filter cartridge retainer stop valve assemblies are provided in the inner cavities of the filter cartridge retainer cylinders and the base retainer cylinders. Filter cartridge locking points are provided at the ends of the filter cartridges.

[0004] The drawback of existing patents is that the locking mechanism of detachable filter cartridges in existing water purifiers has a complex structure, which is prone to problems such as jamming and failure, increasing the maintenance cost of the filter cartridges and reducing their service life. Utility Model Content

[0005] The purpose of this invention is to improve the problem of complex locking mechanism and inconvenient operation of existing detachable filter cartridges in water purifiers, and to provide a water purifier with convenient filter cartridge replacement that allows for quick replacement.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A convenient filter cartridge replacement water purifier includes a housing. The housing includes a support, on which is provided an upward-opening filter cartridge insertion cavity and a filter cartridge snap-fit ​​cavity located on one side of the filter cartridge insertion cavity. The upper part of the inner wall of the filter cartridge snap-fit ​​cavity has several horizontally arranged hooks for snapping onto the filter cartridges. At least two sets of pipe clamp mounting parts are horizontally arranged on the inner wall of the filter cartridge snap-fit ​​cavity, each set including at least two pipe clamp mounting parts distributed vertically. The convenient filter cartridge replacement water purifier described in this technical solution has a filter cartridge insertion cavity for inserting the filter cartridge and a filter cartridge snap-fit ​​cavity for snapping onto the filter cartridge. The filter cartridge insertion cavity only requires inserting the corresponding filter cartridge, and the filter cartridge snap-fit ​​cavity only requires snapping onto the corresponding filter cartridge. The filter cartridge snap-fit ​​cavity features two snap-fit ​​methods. In one method, several hooks are horizontally arranged on the upper part of the cavity's inner wall to snap the filter cartridges in place. A rotating shaft is located on the upper part of the filter cartridge, and this shaft rotates and snaps into the hooks, allowing the filter cartridge to be vertically installed within the cavity. In the other method, pipe clamps are installed on the pipe clamp mounting section. Commonly used small-tonnage filter cartridges can be held in place by these clamps, allowing the filter cartridge to be horizontally installed within the cavity. The horizontally installed filter cartridges are arranged sequentially along the vertical direction. Depending on the filter cartridge specifications, either snap-fit ​​filter cartridges or small-tonnage filter cartridges can be used, improving the water purifier's versatility. Furthermore, the structure of both the insert-type and snap-fit ​​filter cartridge snap-fit ​​cavities is simple, facilitating filter cartridge disassembly and replacement, reducing maintenance costs, and extending the water purifier's lifespan.

[0007] Preferably, the filter element has a rotating shaft at its upper part, which is engaged in the hook to allow the filter element to be vertically installed in the filter element engagement cavity. The central axis of the rotating shaft is perpendicular to the central axis of the filter element, and the rotating shaft is engaged and rotatably disposed in the hook.

[0008] Preferably, the latch includes two upward-facing slots, with both ends of the rotating shaft engaging in the corresponding slots to allow the filter element to rotate along the central axis of the rotating shaft. The two slots are symmetrically arranged to improve the stability of the filter element.

[0009] Preferably, the filter element has a coaxially arranged inlet and outlet water interface on its upper part. The coaxially arranged inlet and outlet water interface form a rotating shaft and are respectively rotated and locked into the corresponding slots.

[0010] Preferably, a limiting plate is provided below the hook, and the vertically installed filter element abuts against the limiting plate. The limiting plate is used to limit the filter element, so as to keep the filter element installed vertically, prevent the lower end of the filter element from shaking and abutting against the filter element locking cavity, and improve the installation stability of the filter element.

[0011] Preferably, the filter element includes a housing and a filter assembly. The housing includes a lower housing and an upper cover, with the upper cover threadedly connected to the lower housing. The rotating shaft is located on the upper cover. When the filter assembly needs to be replaced, the filter element is rotated along the shaft to raise the lower end of the vertically installed filter element. The lower housing is then rotated to separate from the upper cover, while the upper cover remains secured in the hook. The filter assembly inside the lower housing can then be replaced, making installation convenient.

[0012] Preferably, the pipe clamp mounting part is provided with pipe clamps, and the filter element is clamped into the pipe clamps so that the filter element is horizontally installed in the filter element clamping cavity, and the horizontally installed filter elements are distributed sequentially in the vertical direction. The pipe clamps are locked to the pipe clamp mounting part with screws, and the pipe clamps on each set of pipe clamp mounting parts correspond one-to-one, so that the filter element is stably horizontally installed in the filter element clamping cavity.

[0013] Preferably, the pipe clamp mounting part includes a mounting groove disposed within the filter cartridge clamp cavity and a connecting hole disposed within the mounting groove. The mounting groove is used to position the pipe clamp for installation.

[0014] Preferably, the support has an upward-facing pressure tank mounting cavity. The pressure tank mounting cavity and the filter cartridge insertion cavity are arranged along the length of the water purifier, and are located on the same side of the filter cartridge snap-fit ​​cavity. This technical solution cleverly solves the space constraint problem by placing the pressure tank inside the water purifier, using a built-in pressure tank design. There is no need to worry about an additional pressure tank occupying space. The pressure tank mounting cavity and the filter cartridge insertion cavity are located on the same side of the filter cartridge snap-fit ​​cavity, resulting in a compact structure.

[0015] Preferably, the system also includes side cover plates fastened to both sides of the support. The filter element insertion cavity and the filter element snap-fit ​​cavity are located between the two side cover plates. The side cover plates are provided with snap fasteners, and the support is slidably provided with snap-fit ​​blocks that engage with the snap fasteners. The support is used to support the filter element, and the side cover plates are provided on both sides of the support for protection. After the side cover plates are installed on both sides of the support, the snap-fit ​​blocks on the support are slidable to engage with the snap fasteners.

[0016] Specifically, the support has grooves on both sides for corresponding side cover plates. The support also has sliding grooves, some located outside the grooves and some inside. The grooves at the bottom and outside the grooves are parallel. The locking block has a first slide rail and a second slide rail. The first slide rail slides into the groove on the outside of the groove, and the second slide rail slides into the groove at the bottom of the groove. When the side cover plates are placed on both sides of the support, the latches are located within the grooves. Sliding the locking block causes the first slide rail to slide within the groove on the outside of the groove and into the groove itself. At this time, the second slide rail slides into the groove at the bottom of the groove, and the first slide rail and the latches engage.

[0017] Preferably, a left-right limiting component for limiting the horizontal movement of the side cover plate and an outward limiting component for limiting the outward movement of the side cover plate are further provided between the side cover plate and the support. The left-right limiting component includes a snap-fit ​​member disposed on one side of the side cover plate and a snap-fit ​​groove disposed on the support that engages with the snap-fit ​​member. The outward limiting component includes a limiting block disposed on the side cover plate and a T-shaped stop disposed on the support that restricts the side baffle from moving outward toward the support. The other end of the side cover plate is bent toward the support and is provided with a limiting block. The support is provided with a T-shaped stop that engages with the limiting block. The T-shaped stop abuts against the inside and top of the limiting block. The side baffle is installed from top to bottom, and the T-shaped stop prevents the side baffle from moving outward.

[0018] Therefore, this utility model has the following beneficial effects: it can use snap-fit ​​filter cartridges or universal small-t filter cartridges, improving the versatility of the water purifier; it has a filter cartridge insertion cavity and a filter cartridge snap-fit ​​cavity, making the filter cartridge installation structure simple, disassembly and replacement convenient, reducing filter cartridge maintenance costs, and increasing the service life of the water purifier; the built-in pressure tank design cleverly solves the problem of limited space. There is no need to worry about the space occupied by an additional pressure tank. The pressure tank mounting cavity and the filter cartridge insertion cavity are located on the same side of the filter cartridge snap-fit ​​cavity, resulting in a compact structure.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0029] Example 1, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 The water purifier shown is a convenient filter cartridge replacement device, including a housing 5.1. The housing 5.1 includes a support 1. The support 1 has an upward-opening filter cartridge insertion cavity 1.1 and a filter cartridge snap-fit ​​cavity 1.2 located on one side of the filter cartridge insertion cavity 1.1. The upper part of the inner wall of the filter cartridge snap-fit ​​cavity 1.2 is provided with several horizontally arranged hooks 2 for snapping filter cartridges 5. The inner wall of the filter cartridge snap-fit ​​cavity 1.2 is provided with at least two sets of pipe clamp mounting parts 4 for mounting pipe clamps 7. Each set of pipe clamp mounting parts 4 includes at least two pipe clamp mounting parts 4 distributed in the vertical direction.

[0030] A water purifier, also called a water purification machine or water quality purifier, is a water treatment device that deeply filters and purifies water according to usage requirements. Water purifiers use tap water as the input and filter it through different filter cartridges (5) to obtain drinking water. The drinking water from the purifier reaches the pure water level and can be consumed directly. Water from purifiers on the market generally undergoes filtration through multiple filter cartridges (5), such as PP cotton filter cartridges (5), activated carbon filter cartridges (5), ultrafiltration membrane filter cartridges (5), reverse osmosis membrane filter cartridges (5), or composite filter cartridges (5) with equivalent functions (5). Deposits accumulate inside the filter cartridges (5), requiring regular manual cleaning to ensure proper machine operation. Water purifiers use removable filter cartridges (5) for easy replacement; however, the locking mechanism of existing removable filter cartridges on the market is complex, prone to jamming and failure, increasing maintenance costs and reducing lifespan. To improve upon the complex locking mechanism and inconvenient operation of existing removable filter cartridges (5), a water purifier with a convenient filter cartridge replacement feature is proposed.

[0031] The above embodiment of a convenient filter cartridge replacement water purifier includes a filter cartridge insertion cavity 1.1 for inserting filter cartridges 5 and a filter cartridge snap-fit ​​cavity 1.2 for snapping filter cartridges 5. The filter cartridge insertion cavity 1.1 simply requires inserting the corresponding filter cartridge 5, while the filter cartridge snap-fit ​​cavity 1.2 simply requires snapping the corresponding filter cartridge 5 into place. The filter cartridge snap-fit ​​cavity 1.2 has two snap-fit ​​methods. In one method, several hooks 2 for snapping filter cartridges 5 are horizontally arranged on the upper part of the inner wall of the filter cartridge snap-fit ​​cavity 1.2, and a rotating shaft 6 is provided on the upper part of the filter cartridge 5. The rotating shaft 6 rotates and snaps into the hooks 2, so that the filter cartridge 5 is vertically installed in the filter cartridge snap-fit ​​cavity 1.2. In the other method, pipe clamps 7 are provided on the pipe clamp mounting part 4. Commonly used general-purpose small filter cartridges 5 can be clamped in the filter cartridge snap-fit ​​cavity 1.2 by the pipe clamps 7, so that the filter cartridges 5 are horizontally installed in the filter cartridge snap-fit ​​cavity 1.2, and the horizontally installed filter cartridges 5 are distributed sequentially in the vertical direction. Choose one of the snap-fit ​​methods according to the specifications of filter element 5. You can use snap-fit ​​filter element 5 or universal small T filter element 5 to improve the versatility of the water purifier. The design features both a filter element insertion cavity 1.1 for inserting filter element 5 and a filter element snap-fit ​​cavity 1.2 for snap-fit ​​filter element 5. This simple structure makes disassembling and replacing filter element 5 convenient, reducing maintenance costs and extending the lifespan of the water purifier.

[0032] The support 1 is further optimized by providing an upward-opening pressure tank 11 mounting cavity 1.3. The pressure tank 11 mounting cavity 1.3 and the filter cartridge insertion cavity 1.1 are arranged along the length of the water purifier, and are located on the same side of the filter cartridge snap-fit ​​cavity 1.2. This technical solution cleverly solves the space constraint problem by placing the pressure tank 11 inside the water purifier, eliminating the need to worry about the space occupied by an additional pressure tank 11. The pressure tank 11 mounting cavity 1.3 and the filter cartridge insertion cavity 1.1 are located on the same side of the filter cartridge snap-fit ​​cavity 1.2, resulting in a compact structure.

[0033] like Figure 5 As shown, it adopts a seven-stage filtration system, with three filter cartridge insertion chambers 1.1 and one filter cartridge snap-fit ​​chamber 1.2. Four vertically arranged filter cartridges 5 are snapped into the filter cartridge snap-fit ​​chamber 1.2. This seven-stage filtration system can deeply purify water of impurities, bacteria, viruses, heavy metals, and other harmful substances, effectively removing odors and discoloration. Figure 6 As shown, a six-stage filtration system is employed, comprising two filter element insertion chambers 1.1, a pressure tank 11 mounting chamber 1.3, and a filter element snap-fit ​​chamber 1.2. Four vertically arranged filter elements 5 are snapped into the filter element snap-fit ​​chamber 1.2. Figure 7 As shown, the filter element 5, which is horizontally positioned, is secured to the filter element clamping cavity 1.2 by a pipe clamp 7.

[0034] Example 2, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 The water purifier shown is a convenient filter cartridge replacement device, including a housing 5.1. The housing 5.1 includes a support 1. The support 1 has an upward-opening filter cartridge insertion cavity 1.1 and a filter cartridge snap-fit ​​cavity 1.2 located on one side of the filter cartridge insertion cavity 1.1. The upper part of the inner wall of the filter cartridge snap-fit ​​cavity 1.2 is provided with several horizontally arranged hooks 2 for snapping filter cartridges 5. The inner wall of the filter cartridge snap-fit ​​cavity 1.2 is provided with at least two sets of pipe clamp mounting parts 4 for mounting pipe clamps 7. Each set of pipe clamp mounting parts 4 includes at least two pipe clamp mounting parts 4 distributed in the vertical direction.

[0035] In this embodiment, the filter cartridge clamping cavity 1.2 has two clamping methods. In one clamping method, several hooks 2 for clamping filter cartridges 5 are horizontally arranged on the upper part of the inner wall of the filter cartridge clamping cavity 1.2. A rotating shaft 6 is provided on the upper part of the filter cartridge 5. The rotating shaft 6 is rotated and clamped in the hooks 2, so that the filter cartridge 5 is vertically installed in the filter cartridge clamping cavity 1.2. In the other clamping method, a pipe clamp 7 is provided on the pipe clamp mounting part 4. Commonly used general-purpose small-tonnage filter cartridges 5 can be clamped in the filter cartridge clamping cavity 1.2 by the pipe clamp 7, so that the filter cartridges 5 are horizontally installed in the filter cartridge clamping cavity 1.2. The horizontally installed filter cartridges 5 are arranged in sequence along the vertical direction. One clamping method can be selected according to the specifications of the filter cartridge 5. Either clamping filter cartridges 5 or general-purpose small-tonnage filter cartridges 5 can be used to improve the versatility of the water purifier.

[0036] In one type of snap-fit ​​connection, the filter element 5 has a rotating shaft 6 on its upper part. The rotating shaft 6 is snapped into the hook 2 so that the filter element 5 is vertically installed in the filter element snap-fit ​​cavity 1.2. The central axis of the rotating shaft 6 is perpendicular to the central axis of the filter element 5, and the rotating shaft 6 is snapped into and rotated within the hook 2.

[0037] The locking hook 2 is further optimized by including two upward-facing locking slots. The two ends of the rotating shaft 6 are engaged in the corresponding locking slots, so that the filter element 5 can rotate according to the central axis of the rotating shaft 6. The two locking slots are symmetrically arranged to improve the stability of the filter element 5.

[0038] The rotating shaft 6 is further optimized. The upper part of the filter element 5 is provided with a coaxially arranged water inlet and water outlet. The coaxially arranged water inlet and water outlet form the rotating shaft 6, which is rotated and locked into the corresponding slots.

[0039] The hook 2 is further optimized by providing a limiting plate 3 below it. The vertically installed filter element 5 abuts against the limiting plate 3. The limiting plate 3 is used to limit the filter element 5, so that the filter element 5 is kept vertically installed, preventing the lower end of the filter element 5 from shaking and abutting against the filter element locking cavity 1.2, thereby improving the installation stability of the filter element 5.

[0040] The filter element 5 has been further optimized. The filter element 5 includes a housing 5.1 and a filter assembly. The housing 5.1 includes a lower housing 5.1.1 and an upper cover 5.1.2. The upper cover 5.1.2 is threaded onto the lower housing 5.1.1, and a rotating shaft 6 is mounted on the upper cover 5.1.2. When the filter assembly inside the filter element 5 needs to be replaced, the filter element 5 is rotated according to the rotating shaft 6 to raise the lower end of the vertically installed filter element 5. Rotating the lower housing 5.1.1 separates the lower housing 5.1.1 from the upper cover 5.1.2. The upper cover 5.1.2 remains secured in the hook 2. The filter assembly inside the lower housing 5.1.1 can then be replaced, making installation convenient.

[0041] Another snap-fit ​​method involves a pipe clamp 7 on the pipe clamp mounting part 4. The filter element 5 is snapped into the pipe clamp 7, so that the filter element 5 is horizontally installed in the filter element snap-fit ​​cavity 1.2. The horizontally installed filter elements 5 are distributed sequentially in the vertical direction. The pipe clamp 7 is locked to the pipe clamp mounting part 4 with screws. Each set of pipe clamps 7 on the pipe clamp mounting part 4 corresponds one-to-one, so that the filter element 5 is stably and horizontally installed in the filter element snap-fit ​​cavity 1.2.

[0042] Specifically, the pipe clamp mounting part 4 includes a mounting groove 4.1 disposed within the filter element clamp cavity 1.2 and a connecting hole 4.2 disposed within the mounting groove 4.1. The mounting groove 4.1 is used to position the pipe clamp 7 for installation.

[0043] The support 1 is further optimized by providing an upward-opening pressure tank 11 mounting cavity 1.3. The pressure tank 11 mounting cavity 1.3 and the filter cartridge insertion cavity 1.1 are arranged along the length of the water purifier, and are located on the same side of the filter cartridge snap-fit ​​cavity 1.2. This technical solution cleverly solves the space constraint problem by placing the pressure tank 11 inside the water purifier, eliminating the need to worry about the space occupied by an additional pressure tank 11. The pressure tank 11 mounting cavity 1.3 and the filter cartridge insertion cavity 1.1 are located on the same side of the filter cartridge snap-fit ​​cavity 1.2, resulting in a compact structure.

[0044] Based on Embodiment 2, the basic structure of support 1 is further optimized, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8As shown, a water purifier with convenient filter replacement includes a housing 5.1. The housing 5.1 includes a support 1. The support 1 has an upward-opening filter insert cavity 1.1 and a filter snap-fit ​​cavity 1.2 located on one side of the filter insert cavity 1.1. The upper part of the inner wall of the filter snap-fit ​​cavity 1.2 is provided with several hooks 2 for snapping filter elements 5. The inner wall of the filter snap-fit ​​cavity 1.2 is provided with at least two sets of pipe clamp mounting parts 4 for mounting pipe clamps 7. Each set of pipe clamp mounting parts 4 includes at least two pipe clamp mounting parts 4 distributed in the vertical direction.

[0045] In this embodiment, side cover plates 8 are also attached to both sides of the support 1. The filter element insertion cavity 1.1 and the filter element snap-fit ​​cavity 1.2 are located between the two side cover plates 8. The side cover plates 8 are provided with snap fasteners 8.1, and the support 1 is slidably provided with snap-fit ​​blocks 9 that engage with snap fasteners 8.1. The support 1 is used to support the filter element 5, and the side cover plates 8 are provided on both sides of the support 1 for protection. After the side cover plates 8 are installed on both sides of the support 1, the snap-fit ​​blocks 9 on the support 1 are slid to engage with snap fasteners 8.1.

[0046] Specifically, the support 1 has grooves 1.4 on both sides for the side cover plate 8. The support 1 has sliding grooves 1.5, some of which are located outside the groove 1.4 and some inside. The sliding grooves 1.5 at the bottom and outside the groove 1.4 are parallel. The locking block 9 has a first slide rail 9.1 and a second slide rail 9.2. The first slide rail 9.1 slides in contact with the sliding groove 1.5 outside the groove 1.4, and the second slide rail 9.2 slides in contact with the sliding groove 1.5 at the bottom of the groove 1.4. When the side cover plate 8 is placed on both sides of the support 1, the latch 8.1 is located in the groove 1.4. When the locking block 9 is slidable, the first slide rail 9.1 slides in the sliding groove 1.5 outside the groove 1.4 and slides into the groove 1.4. At this time, the second slide rail 9.2 slides in contact with the sliding groove 1.5 at the bottom of the groove 1.4, and the first slide rail 9.1 and the latch 8.1 are engaged.

[0047] The limiting structure between the side cover plate 8 and the support 1 is further optimized. A left-right limiting assembly for limiting the horizontal movement of the side cover plate 8 and an outward limiting assembly for limiting the outward movement of the side cover plate 8 are also provided between the side cover plate 8 and the support 1. The left-right limiting assembly includes a snap-fit ​​member 8.2 on one side of the side cover plate 8 and a snap-fit ​​groove 1.6 on the support 1 that engages with the snap-fit ​​member 8.2. The outward limiting assembly includes a limiting block 1.7 on the side cover plate 8 and a T-shaped stop 8.3 on the support 1 to restrict the side baffle from moving outward toward the support 1. The other end of the side cover plate 8 is bent toward the support 1 and has a limiting block 1.7. The support 1 has a T-shaped stop 8.3 that engages with the limiting block 1.7. The T-shaped stop 8.3 abuts against the inside and top of the limiting block 1.7. The side baffle is installed from top to bottom, and the T-shaped stop 8.3 prevents the side baffle from moving outward.

[0048] The support 1 is further optimized by providing an upward-opening pressure tank 11 mounting cavity 1.3. The pressure tank 11 mounting cavity 1.3 and the filter cartridge insertion cavity 1.1 are arranged along the length of the water purifier, and are located on the same side of the filter cartridge snap-fit ​​cavity 1.2. This technical solution cleverly solves the space constraint problem by placing the pressure tank 11 inside the water purifier, eliminating the need to worry about the space occupied by an additional pressure tank 11. The pressure tank 11 mounting cavity 1.3 and the filter cartridge insertion cavity 1.1 are located on the same side of the filter cartridge snap-fit ​​cavity 1.2, resulting in a compact structure.

[0049] The specific embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the specific scope of implementation of this utility model. All equivalent changes made to the shape and structure of this utility model should be included within the protection scope of this utility model.
