Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a water purifier. Background Technology

[0002] With the development of the times, people have increasingly higher requirements for drinking water, and water purifiers have been recognized and purchased by most people. Water purifiers can purify water sources such as municipal tap water, thereby providing users with high-quality purified water.

[0003] Filter cartridges are the core component of water purifiers. Filter cartridges can include PP cotton filters, activated carbon filters, nanofiltration filters, and reverse osmosis filters, among others. These cartridges can filter harmful substances from the raw water. However, with prolonged use, the filtration efficiency of the cartridges decreases due to the effects of contaminants and their own aging. Therefore, filter cartridges need to be replaced regularly.

[0004] Filter cartridges can be installed on filter holders using methods such as screw-on or straight-insertion. Taking a type of straight-insertion filter cartridge currently on the market as an example, the water inlet of the filter cartridge is located at one end along the extension direction of the filter cartridge. Users need to insert or remove the filter cartridge from the filter holder along the extension direction of the filter cartridge. Filter cartridges are usually installed inside the water purifier, and this installation method is obviously not suitable for situations where there is only a small gap between the filter cartridge and the inner wall of the water purifier. Utility Model Content

[0005] To at least partially address the problems existing in the prior art, some embodiments of this utility model provide a water purifier, including: a filter cartridge compartment with a compartment opening on its front side; a mounting base disposed on the top of the filter cartridge compartment, the mounting base having a filter seat water inlet extending along a first direction; and a filter cartridge, the filter cartridge including a mounting head located on its top, the mounting head having a filter cartridge water inlet extending along the first direction, the filter cartridge being detachably installed into the filter cartridge compartment via the compartment opening along the first direction, wherein, in the installed state where the filter cartridge is installed to the mounting base: the mounting head is installed to the mounting base, the filter cartridge water inlet and the filter seat water inlet are interconnected; and there is an angle between the first direction and the length direction of the filter cartridge.

[0006] The filter cartridge can be installed in relatively small filter cartridge compartments (e.g., whose height is close to its length), eliminating the need to move the cartridge along its extension direction during installation and removal. Therefore, this solution is suitable for water purifiers with a compact internal layout, eliminating the need for additional space for filter cartridge movement. Filter cartridge removal and installation are simple, as the cartridge can be pulled out along the first direction or inserted into the compartment facing away from the first direction. Furthermore, the filter cartridge's water inlet and the filter base's water inlet extend horizontally, minimizing internal water accumulation and making replacement even more convenient.

[0007] For example, the water purifier also includes a limiting member, which is movably disposed on top of the filter cartridge compartment between a limiting position and a release position. The limiting position is below the release position. When the limiting member is in the limiting position, the mounting head is constrained on the mounting base facing away from the first direction. When the limiting member is in the release position, the mounting head can detach from the mounting base along the first direction. Compared to relying solely on the friction between the filter cartridge inlet and the filter base inlet for positioning, by setting the limiting member, the connection between the filter cartridge inlet and the filter base inlet can be prevented from loosening due to aging from long-term use or vibration of the water purifier, which could lead to the filter cartridge falling off or water leakage at the connection. Positioning the limiting position below the release position also ensures that the limiting member remains in the limiting position under the action of gravity.

[0008] For example, the mounting head is provided with a limiting groove, which has an open end at one end and a stop end at the other end. A limiting protrusion is provided on the limiting member, which can enter the limiting groove through the open end. When the limiting member is in the limiting position, the limiting protrusion abuts against the stop end, and the mounting head is constrained on the mounting base. Therefore, the limiting member does not fix the filter element by a circumferential gripping method, but rather employs a more reliable locking structure, making it less likely for the filter element to loosen and fall off.

[0009] For example, the limiting member is pivotable between a limited position and a released position about an axis parallel to the second direction, which is perpendicular to the first direction. In the limited position, the limiting member is horizontal. Thus, the user can operate the limiting member through the compartment opening located in the first direction of the filter cartridge compartment and remove the filter cartridge. In the limited position, the limiting member can be horizontal, maximizing the distance between its end and the pivot axis for the most stable locking effect.

[0010] For example, the limiting groove includes a first groove segment extending downwardly at an incline toward the outer side of the filter cartridge compartment, and a second groove segment extending vertically. The upper end of the first groove segment forms an open end, and the second groove segment connects to the lower end of the first groove segment, forming a stop end. Thus, the first and second groove segments can cooperate with the limiting protrusion, serving a guiding function during filter cartridge installation and removal. During installation, this ensures the filter cartridge is installed correctly; during removal, it allows the filter cartridge to be moved in the first direction for easy disassembly. With the second groove segment having a certain incline angle, it also prevents the limiting protrusion from sliding from the stop end toward the open end when the filter cartridge is subjected to external force.

[0011] For example, the mounting head has limiting grooves on both opposite sides along the second direction, and the limiting member has limiting protrusions on both opposite sides along the second direction. When the limiting protrusions apply a guiding force to the limiting grooves, no torque is generated that would cause the filter element to rotate. This ensures that the filter element water inlets near both sides of the filter element are inserted into the filter base water inlets simultaneously, preventing the filter element from getting stuck or even damaged due to uneven force. Limiting from both sides is also more reliable when the limiting protrusions do not apply a guiding force to the limiting grooves.

[0012] For example, the limiting member includes: a first clamp arm and a second clamp arm located on both sides of the mounting head, with limiting protrusions disposed on the first and second clamp arms; and a connecting beam connecting the first and second clamp arms. When the limiting member is in the limiting position, the connecting beam is closer to the compartment opening than the filter element and is spaced apart from the filter element. Thus, the limiting protrusion can limit the limiting groove from both sides, or further apply a guiding force to the limiting groove from both sides. When operating the limiting member, the user can simultaneously lift or press the first and second clamp arms. For example, parts such as the housing assembly that need to cover the compartment opening do not need to be designed with clearance from the limiting member. The connecting beam being spaced apart from the filter element facilitates user operation.

[0013] For example, the limiting member is pivotable between a limited position and a released position about an axis parallel to a second direction, which is perpendicular to the first direction. The filter element also includes a filter body, and the horizontal cross-section of the mounting head is smaller than that of the filter body. The top surface of the mounting head is connected to the front surface of the mounting head via an arc surface. When the limiting assembly is in the limited position, the outer dimensions of the first clamp arm and the second clamp arm can be close to or the same as the dimensions of the filter body. The arc surface can avoid the connecting beam of the limiting assembly in the limited position.

[0014] For example, the water purifier also includes a housing assembly comprising a rear shell and a front door. The front door is closably connected to the rear shell, and the front door and rear shell together form an inner cavity. A filter cartridge compartment is disposed in the inner cavity, with its opening facing the front door. The openable front door facilitates routine maintenance and upkeep of the built-in beverage purifier, eliminating the need for users to remove or pull it out of its housing, reducing workload, and decreasing the possibility of the built-in beverage purifier tipping over due to instability when pulled out of its housing.

[0015] For example, the front door is pivotally connected to the rear shell between an open and closed position about a pivot axis extending vertically. Thus, the front door can pivot about the pivot axis. Lateral opening typically does not obstruct user operation and requires no additional retaining structure, combining cost and convenience.

[0016] For example, the water purifier is a built-in water purifier. Using the above-described method to secure the filter cartridge facilitates its installation and removal. Furthermore, this installation method allows for filter cartridge replacement with only the front door open, without needing to remove it from its housing.

[0017] This utility model description introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

Detailed Implementation

[0025] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0026] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0027] This application provides a water purifier. For example... Figure 1 As shown, the water purifier may include a filter compartment 100 and a filter element 300, with the filter compartment 100 having a compartment opening 110 on its front side. In some embodiments, the filter compartment 100 may be a housing assembly 200 of the water purifier, and other components of the water purifier may also be disposed within the filter compartment 100. Figure 1 In the illustrated embodiment, the filter cartridge compartment 100 is disposed within the housing assembly 200, separating the filter cartridge 300 from other components of the water purifier, thereby preventing water flowing out when replacing the filter cartridge 300 from affecting the operation of the water purifier. The compartment opening 110 may face the front, back, or side of the water purifier. In some embodiments, the compartment opening 110 may be provided with a separate baffle. In other embodiments, the compartment opening 110 may be covered by the housing assembly 200 of the water purifier.

[0028] The filter element 300 may include a mounting head 310 located on its top, the mounting head 310 having a filter element water inlet 311 extending in a first direction. Figure 1 In the illustrated embodiment, the water purifier may include a first filter element 301 and a second filter element 302. Taking the first filter element 301 and the second filter element 302 as a pre-filter and a central filter element, respectively, the pre-filter element may be a composite filter element, located before the central filter element, used to perform preliminary filtration of the water entering the central filter element to extend the service life of the central filter element. The central filter element may include a reverse osmosis filter element, an ultrafiltration filter element, a nanofiltration filter element, or a filter element composed of any two or more of them. For reverse osmosis and nanofiltration filter elements, the water needs to be pressurized before entering the filter element; in this case, the water purifier may also include a booster pump.

[0029] For pre-filters and central filters that do not include reverse osmosis or nanofiltration filters, the filter inlet 311 may only include an inlet and an outlet. For central filters that include reverse osmosis and / or nanofiltration filters, since both filters produce a certain proportion of concentrate during operation, the filter inlet also includes a concentrate outlet. Filter 300 includes a filter body 320, which can extend perpendicular to a first direction, allowing filter 300 to be installed in the water purifier along the first direction perpendicular to the extension direction of the filter body 320.

[0030] The water purifier may further include a mounting base 400, which can be disposed on top of the filter cartridge compartment 100, and the mounting base 400 has a filter seat water inlet 410 extending along a first direction. Thus, the filter cartridge 300 can be detachably installed into the filter cartridge compartment 100 via the compartment opening 110 along the first direction. In the installed state where the filter cartridge 300 is installed on the mounting base 400, the mounting head 310 is installed on the mounting base 400, and the filter cartridge water inlet 311 communicates with the filter seat water inlet 410. An angle is formed between the first direction and the length direction of the filter cartridge 300. Optionally, the length direction of the filter cartridge 300 is perpendicular to the first direction.

[0031] Filter element 300 can be installed in a relatively small filter cartridge compartment 100 (e.g., its height is close to its length), without needing to move it along its extension direction during installation and removal. Therefore, this solution is suitable for water purifiers with a compact internal layout, eliminating the need for additional space for filter element 300 installation and removal. Filter element 300 can be easily removed and installed by pulling out the filter cartridge compartment 100 along the first direction or inserting it into the compartment with the filter element 300 facing away from the first direction. Furthermore, the filter element water inlet 311 and the filter base water inlet 410 extend horizontally, resulting in less water accumulation inside and making replacement more convenient.

[0032] refer to Figure 2Exemplary, the water purifier may further include a limiting member 500. The limiting member 500 is movably disposed on top of the filter cartridge compartment 100 between a limiting position and a release position. In some embodiments, the limiting member 500 may be configured as a clamp with an opening on one side, and the removal direction of the filter cartridge 300 faces away from the opening of the clamp. Movement of the filter cartridge 300 is blocked by inserting it into the opening of the clamp. In other embodiments, the limiting member 500 may have a snap-fit ​​function into the filter cartridge 300, thereby limiting the filter cartridge 300. In the embodiment shown in the figures, the limiting member 500 may pivot about a pivot axis. In another exemplary embodiment, the limiting member 500 may translate vertically via a guide rail. This causes the mounting head 310 to be confined to the mounting base 400 facing away from the first direction when the limiting member 500 is in the limiting position. And when the limiting member 500 is in the release position, the mounting head 310 is disengaged from the mounting base 400 along the first direction.

[0033] Compared to relying solely on the friction between the filter cartridge water inlet 311 and the filter base water inlet 410 for positioning, the addition of a limiting component 500 prevents the connection between the filter cartridge water inlet 311 and the filter base water inlet 410 from loosening due to aging from long-term use or vibration of the water purifier, thus preventing the filter cartridge 300 from falling off or leaking at the connection. Positioning the limiting component 500 below the release position also ensures that it remains in the limiting position under gravity.

[0034] Reference Figure 2 and Figure 3 For example, the mounting head 310 is provided with a limiting groove 312, which has an open end 3121A at one end and a stop end 3122A at the other end. The limiting member 500 is provided with a limiting protrusion 510, which can enter the limiting groove 312 via the open end 3121A. As described above, since the limiting position is below the release position, the limiting groove 312 also extends substantially vertically. In the embodiment shown in the figure, the open end 3121A of the limiting groove 312 is further away from the first direction than the stop end 3122A, thereby preventing the limiting protrusion 510 from sliding from the stop end 3122A toward the open end 3121A when the filter element 300 is subjected to external force. When the limiting member 500 is in the limiting position, the limiting protrusion 510 abuts against the stop end 3122A, and the mounting head 310 is limited on the mounting base 400. Therefore, the limiting component 500 does not fix the filter element 300 by wrapping around it, but adopts a more reliable locking structure, making it less likely for the filter element 300 to loosen or fall off.

[0035] For example, the limiting member 500 is pivotable between a limiting position and a releasing position about an axis parallel to a second direction, the second direction being perpendicular to the first direction, and the limiting member 500 is in a horizontal state in the limiting position. Figure 3 In the illustrated embodiment, the limiting member 500 is mounted on the inner wall of the filter cartridge compartment 100 via a hinge 420, thereby allowing pivoting. In other embodiments, both the limiting member 500 and the inner wall of the filter cartridge compartment 100 are provided with holes, through which fasteners pass to fix the limiting member 500 to the inner wall of the filter cartridge compartment 100, allowing the limiting member 500 to pivot about the fasteners. Thus, the user can operate the limiting member 500 through the compartment opening 110 located in the first direction of the filter cartridge compartment 100 and remove the filter cartridge 300. When in the limited position, the limiting member 500 can be horizontal, maximizing the distance between its end and the pivot axis for the most stable locking effect.

[0036] For example, the limiting groove 312 includes a first groove segment 3121 extending downwardly toward the outer side of the filter cartridge 100, and a second groove segment 3122 extending vertically. The upper end of the first groove segment 3121 may form an open end 3121A, and the second groove segment 3122 is connected to the lower end of the first groove segment 3121, forming a stop end 3122A. Figure 3 In the illustrated embodiment, the limiting protrusion 510 may have a cylindrical vertical cross-section. As the limiting assembly moves from the release position to the limiting position, the limiting protrusion 510 can enter the first groove segment 3121 from the opening end 3121A, and its edge can apply a guiding force against the first direction to the mounting head 310 of the filter element 300. Thus, the filter element water inlet 311 can be further inserted into the filter seat water inlet 410. When the limiting protrusion 510 reaches the junction of the first groove segment 3121 and the second groove segment 3122, the filter element water inlet 311 and the filter seat water inlet 410 are fully engaged. Subsequently, the limiting protrusion 510 can enter the second groove segment 3122, thereby limiting the mounting head 310 in the first direction. The stop end 3122A can support the limiting protrusion 510, keeping the limiting assembly horizontal when in the limiting position. Conversely, as the limiting component moves from the limiting position to the releasing position, the limiting protrusion 510 can apply a guiding force in the first direction to the mounting head 310 in the first groove section 3121, causing the filter element water inlet 311 and the filter seat water inlet 410 to partially separate, making it easier to remove the filter element 300.

[0037] In some embodiments, the second groove segment 3122 is completely vertical. In the embodiment shown in the figure, the second groove segment 3122 may have an inclination direction opposite to that of the first groove segment 3121, and the inclination angle with the vertical direction is smaller than the inclination angle of the first groove segment 3121 with the vertical direction. Thus, the first groove segment 3121 and the second groove segment 3122 can cooperate with the limiting protrusion 510 to guide the filter element 300 during installation and removal. During installation, it can ensure that the filter element 300 is installed in place; during disassembly, it can move the filter element 300 in the first direction to facilitate disassembly. When the second groove segment 3122 has a certain inclination angle, it can also prevent the limiting protrusion 510 from sliding from the stop end 3122A toward the opening end 3121A when the filter element 300 is subjected to external force.

[0038] Exemplarily, the mounting head 310 is provided with limiting grooves 312 on both sides opposite to each other along the second direction, and the limiting member 500 is provided with limiting protrusions 510 on both sides opposite to each other along the second direction. As described above, the limiting grooves 312 can guide the mounting head 310. By correspondingly providing the limiting grooves 312 and the limiting protrusions 510 on both sides opposite to each other along the second direction, when the limiting protrusions 510 apply a guiding force to the limiting grooves 312, no torque is generated that causes the filter element 300 to rotate. This allows the filter element water inlets 311 near both sides of the filter element 300 to be inserted into the filter seat water inlets 410 simultaneously, preventing the filter element 300 from being stuck or even damaged due to uneven force. In embodiments where the limiting protrusions 510 do not apply a guiding force to the limiting grooves 312, the limiting protrusions 510 limiting the limiting grooves 312 from both sides is also more reliable.

[0039] Exemplarily, the limiting member 500 includes a first clamping arm 501 and a second clamping arm 502 located on both sides of the mounting head 310, with a limiting protrusion 510 disposed on the first clamping arm 501 and the second clamping arm 502. Thus, the limiting protrusion 510 can limit the limiting groove 312 from both sides, or further apply a guiding force to the limiting groove 312 from both sides. The limiting member 500 also includes a connecting beam 503 connected between the first clamping arm 501 and the second clamping arm 502, allowing the user to simultaneously lift or press the first clamping arm 501 and the second clamping arm 502 when operating the limiting member 500. This is particularly suitable for limiting members 500 that employ a pivoting structure to move between a limited position and a released position. When the limiting member 500 is in the limited position, the connecting beam 503 is closer to the compartment opening 110 than the filter element 300 and spaced apart from the filter element 300. This prevents the limiting component from protruding from the compartment opening 110. Therefore, parts such as the housing assembly 200 that need to cover the compartment opening 110 do not require clearance from the limiting assembly. The connecting beam 503 is spaced apart from the filter element 300, which facilitates user operation.

[0040] For example, the filter element 300 also includes a filter body 320, the horizontal cross-section of the mounting head 310 is smaller than the horizontal cross-section of the filter body 320, and the top surface of the mounting head 310 is connected to the front surface of the mounting head 310 by an arc surface. Figure 3 In the illustrated embodiment, the distance between the inner sides of the first clamp arm 501 and the second clamp arm 502 can be greater than the size of the mounting head 310. When the limiting component is in the limiting position, the outer dimensions of the first clamp arm 501 and the second clamp arm 502 can be close to or the same as the size of the filter body 320. The arc surface can avoid the connecting beam 503 of the limiting component in the limiting position.

[0041] As described above, the water purifier includes a housing assembly 200. (Return to reference) Figure 1 Exemplarily, the housing assembly 200 includes a rear housing 210 and a front door 220, the front door 220 being openable and closable on the rear housing 210, the front door 220 and the rear housing 210 together forming an inner cavity 230. Exemplarily, the front door 220 can be opened by pivoting, translation, etc. In one embodiment, a hinge is provided between the front door 220 and the rear housing 210, allowing it to be opened by pivoting. In another embodiment, the front door 220 can be opened by sliding laterally. In the open state, the inner cavity 230 can be exposed. Only one front door 220 is shown in the figure; in embodiments not shown, there may be more than one front door, for example, a double-door structure. A filter cartridge compartment 100 is disposed in the inner cavity 230, the compartment opening 110 of the filter cartridge compartment 100 facing the front door 220. The openable front door makes it easy for users to perform routine maintenance on the built-in beverage machine. Users do not need to remove or pull the built-in beverage machine out of the housing, which reduces the workload and reduces the possibility of the built-in beverage machine tipping over due to instability when it is pulled out of the housing.

[0042] For example, the front door 220 is pivotally connected to the rear housing 210 between an open and closed position about a pivot axis extending vertically. Thus, the front door 220 can pivot about the pivot axis. Lateral opening typically does not obstruct user operation and requires no additional retaining structure, combining cost and convenience.

[0043] For example, the water purifier is a built-in water purifier. Because the installation space of a built-in water purifier is limited, its internal space is relatively compact. Using the above-described method to fix the filter element 300 facilitates its installation and removal. Furthermore, this installation method allows the filter element 300 to be replaced by simply opening the front door 220, without having to remove it from its housing.
