Description

Technical Field

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

[0002] Traditional water purifier filter cartridges use a screw-on replacement mechanism. The cartridge is fixed to the water channel plate via a rotating structure at the bottom. This requires aligning the inlet and outlet of the cartridge with the water channel plate before rotating it. This rotation process can easily cause deformation and damage to the water channel plate. With frequent use, the connection between the filter cartridge and the water channel plate can become misaligned, posing a risk of leakage. Furthermore, the existing screw-on replacement method is laborious, making it difficult for users to apply force during replacement. The complex process makes cartridge replacement inconvenient and negatively impacts the user experience. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of existing water purifier filter cartridge replacement structures, such as easy structural damage, high risk of water leakage, and inconvenience in cartridge replacement, and to provide a filter cartridge assembly and a water purifier.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] This utility model provides a filter element assembly, which includes a filter element body, a first elastic element, a housing, a guide element, a guide groove, and a claw assembly. The filter element body is disposed inside the housing, the first elastic element is disposed between the filter element body and the housing, and the elastic force direction of the first elastic element is at least along the movement direction of the filter element body. One end of the claw assembly is movably connected to the housing, and the other end of the claw assembly is detachably connected to the filter element body.

[0006] The guide groove is provided in one of the claw assembly and the housing, one end of the guide member is connected to the other of the claw assembly and the housing, and the other end of the guide member can slide in the guide groove;

[0007] The guide groove is provided with a first position and a second position. Under the combined action of external force and the elastic force of the first elastic member, the guide member is configured to switch between the first position and the second position. When the guide member is in the first position, the filter element body is connected to the claw assembly. When the guide member is in the second position, the filter element body is disengaged from the claw assembly.

[0008] In this design, the filter element body is housed within the outer casing, and a first elastic element is positioned between the filter element body and the outer casing. The elastic force of the first elastic element is at least along the direction of movement of the filter element body, thus providing elastic force in that direction. A guide groove is located in one of the claw assembly and the outer casing, and one end of a guide member is connected to the other of the claw assembly and the outer casing, while the other end of the guide member can slide within the guide groove. The guide groove has a first position and a second position. Under the combined action of external force and the elastic force of the first elastic element, the guide member is configured to switch between the first and second positions. When the guide member is in the first position, the filter element body is connected to the claw assembly, fixing the filter element body to the outer casing. When the guide member is in the second position, the filter element body disengages from the claw assembly, detaching the filter element body from the outer casing. The user only needs to apply external force for the filter element body to connect and disconnect from the outer casing under the combined action of the external force and the elastic force of the elastic element. This design is labor-saving, improving the convenience of filter element replacement, reducing the risk of structural damage, and preventing misalignment during filter element installation, thus lowering the risk of filter element leakage.

[0009] Preferably, the claw assembly includes a claw body, a base plate, and a limiting member, wherein the claw body is rotatably connected to the base plate, and the limiting member can restrict the rotation of the claw body;

[0010] When the guide is in the first position, the limiting member abuts against the claw body to connect the claw body to the filter element body; when the guide is in the second position, the limiting member disengages from the claw body to disengage the claw body from the filter element body.

[0011] In this design, the claw body is rotatably connected to the base plate, and the limiting member restricts the rotation of the claw body. When the guide member is in the first position, the limiting member abuts against the claw body, restricting the claw body to the position where it connects with the filter element body, thus connecting the claw body to the filter element body and enabling the installation of the filter element body. When the guide member is in the second position, the limiting member disengages from the claw body, no longer restricting the claw body to the position where it connects with the filter element body, thus detaching the claw body from the filter element body and enabling the disassembly of the filter element body.

[0012] Preferably, the claw assembly further includes a second elastic element, which is disposed between the base plate and the filter element body, and the contact surface between the claw body and the filter element body is not parallel to the elastic force direction of the second elastic element.

[0013] In this solution, by setting the contact surface between the claw body and the filter element body to be non-parallel to the elastic direction of the second elastic element, when the filter element body is connected to the claw body, the second elastic element can apply elastic force in the direction of the contact surface between the claw body and the filter element body, so that the filter element body can be more firmly connected to the shell.

[0014] Preferably, the outer periphery of the base plate is provided with a groove, and the claw body is rotatably connected to the groove so that the claw body can rotate toward or away from the filter body.

[0015] In this design, the outer periphery of the base plate is provided with a groove, and the claw body is rotatably connected to the groove. The claw body can rotate within the groove, thereby allowing the claw body to move closer to or further away from the filter element body. When the claw body is close to the filter element body, it can connect with the filter element body; when the claw body is far away from the filter element body, it can detach from the filter element body.

[0016] Preferably, the claw assembly further includes an elastic part, which is disposed at the connection between the claw body and the base plate, and the elastic part is used to provide a force for the claw body to rotate away from the filter body.

[0017] In this solution, an elastic part is provided at the connection between the claw body and the base plate. The elastic part is used to provide a force for the claw body to rotate away from the filter element body. Thus, when the claw body loses the restraint of the limiting member, the elastic part can provide a force for the claw body to rotate away from the filter element body, so that the claw body can detach from the filter element body more quickly and make it easier to disassemble the filter element body.

[0018] Preferably, the limiting member is sleeved on the outside of the claw body, the limiting member is provided with a through hole, one end of the guide member is rotatably connected to the base plate, and the other end of the guide member slides in the guide groove through the through hole.

[0019] In this solution, by providing a through hole on the limiting member, the through hole is used for the guide member to pass through, so that one end of the guide member can be connected to the base plate, and the other end of the guide member can slide in the guide groove through the through hole, thereby avoiding the limiting member from obstructing the guide member from sliding in the guide groove.

[0020] Preferably, the guide groove includes a first guide groove and a second guide groove, the first guide groove being used for the guide member to slide from the first position to the second position, and the second guide groove being used for the guide member to slide from the second position to the first position.

[0021] In this design, the guide groove includes a first guide groove and a second guide groove. When the filter element body needs to be disassembled, under the action of external force and the elastic force of the first elastic element, the guide member slides within the first guide groove, moving from a first position to a second position, causing the claw body to disengage from the filter element body, thereby detaching the filter element body from the outer shell. When the filter element body needs to be installed, under the action of external force and the elastic force of the first elastic element, the guide member slides within the second guide groove, moving from a second position to a first position, causing the claw body to connect to the filter element body, thereby connecting the filter element body to the outer shell.

[0022] Preferably, the first guide groove includes a first part and a second part, which are connected sequentially from the first position to the second position. The first part is configured such that when the filter body is subjected to an external force, the guide member can slide from the first part to the second part. The second part is configured such that under the elastic force of the first elastic member, the guide member can slide from the second part to the second position.

[0023] In this design, the first guide groove includes a first part and a second part, which are sequentially connected from a first position to a second position. When the filter element body is subjected to an external force, the guide member can slide from the first part to the second part. At the same time, the first elastic member is compressed under the external force. When the first elastic member loses the external force, its elastic force is released, and the guide member can slide from the second part to the second position under the elastic force of the first elastic member. The claw body disengages from the filter element body, thereby causing the filter element body to detach from the outer shell.

[0024] Preferably, the second guide groove includes a third part and a fourth part, the third part and the fourth part being sequentially connected from the second position to the first position. The third part is configured such that when the filter body is subjected to an external force, the guide member can slide from the third part to the fourth part; the fourth part is configured such that under the elastic force of the first elastic member, the guide member can slide from the fourth part to the first position.

[0025] In this design, the second guide groove includes a third part and a fourth part, which are sequentially connected from the second position to the first position. When the filter element body is subjected to an external force, the guide member can slide from the third part to the fourth part. At the same time, the first elastic member is compressed under the external force. Then, when the first elastic member loses the external force, the elastic force of the first elastic member is released, and the guide member can slide from the fourth part to the first position under the elastic force of the first elastic member. The claw body connects with the filter element body, thereby connecting the filter element body to the outer shell.

[0026] This embodiment provides a water purifier, which includes the filter assembly described above.

[0027] The positive and progressive effects of this utility model are as follows:

[0028] The filter element assembly includes a filter element body, a first elastic element, a housing, a guide element, a guide groove, and a claw assembly. The filter element body is disposed within the housing, and the first elastic element is disposed between the filter element body and the housing. The elastic force of the first elastic element is at least along the direction of movement of the filter element body, thereby providing elastic force in the direction of movement of the filter element body. The guide groove is disposed in one of the claw assembly and the housing, and one end of the guide element is connected to the other of the claw assembly and the housing, while the other end of the guide element can slide within the guide groove. The guide groove has a first position and a second position. Under the combined action of an external force and the elastic force of the first elastic element, the guide element is configured to switch between the first position and the second position. When the guide element is in the first position, the filter element body is connected to the claw assembly, thereby fixing the filter element body to the housing. When the guide element is in the second position, the filter element body disengages from the claw assembly, thereby detaching the filter element body from the housing. Users only need to apply external force, and the filter element body can connect and detach from the outer shell under the action of external force and elastic force of elastic components. It has the characteristics of saving effort, thereby improving the convenience of users to replace the filter element, and is less likely to cause structural damage. At the same time, the filter element is not easy to be misaligned during installation, reducing the risk of water leakage. Attached Figure Description

[0057] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the following embodiments.

[0058] like Figures 1-5 As shown in the figure, this embodiment provides a water purifier, which includes a filter assembly 100.

[0059] The filter element assembly 100 includes a filter element body 110, a first elastic element 200, a housing 300, a guide element 400, a guide groove 500, and a claw assembly 600. The filter element body 110 is disposed within the housing 300. The first elastic element 200 is disposed between the filter element body 110 and the housing 300. The elastic force of the first elastic element 200 is at least along the movement direction x of the filter element body, thereby providing elastic force in the movement direction x of the filter element body. One end of the claw assembly 600 is movably connected to the housing 300, and the other end of the claw assembly 600 is detachably connected to the filter element body 110. The guide groove 500 is disposed in one of the claw assembly 600 and the housing 300. One end of the guide element 400 is connected to the other of the claw assembly 600 and the housing 300, and the other end of the guide element 400 can slide within the guide groove 500.

[0060] The guide groove 500 has a first position 710 and a second position 720. Under the combined action of external force and the elastic force of the first elastic member 200, the guide member 400 is configured to switch between the first position 710 and the second position 720. When the guide member 400 is in the first position 710, the filter element body 110 is connected to the claw assembly 600 to fix the filter element body 110 to the housing 300. When the guide member 400 is in the second position 720, the filter element body 110 disengages from the claw assembly 600 to detach from the housing 300. The user only needs to apply external force for the filter element body 110 to connect and disconnect from the housing 300 under the action of external force and the elastic force of the first elastic member 200. This is labor-saving, thereby improving the convenience of filter element replacement for users, reducing the risk of structural damage, and preventing misalignment of the filter element during installation, thus reducing the risk of filter element leakage.

[0061] In this embodiment, the guide groove 500 is disposed on the claw assembly 600, one end of the guide member 400 is connected to the housing 300, and the other end of the guide member 400 slides within the guide groove 500, thereby allowing the other end of the guide member 400 to switch between a first position 710 and a second position 720. In other embodiments, the guide groove 500 may also be disposed on the housing 300, one end of the guide member 400 may be connected to the claw assembly 600, and the other end of the guide member 400 may slide within the guide groove 500.

[0062] In this embodiment, the filter element body 110 moves vertically. The user applies a vertical external force by pressing the filter element body 110, and the first elastic element 200 provides a vertical elastic force. In other embodiments, those skilled in the art can determine the movement direction x of the filter element body and the direction of the elastic force of the first elastic element 200 according to actual needs.

[0063] In this embodiment, a slot is provided on the first position 710, and the guide member 400 can be engaged in the slot. No limiting structure is provided on the second position 720. In other embodiments, slots may also be provided on both the first position 710 and the second position 720. Those skilled in the art can select appropriate specific structures for the first position 710 and the second position 720 according to actual needs.

[0064] like Figure 4As shown, the claw assembly 600 includes a claw body 610, a base plate 620, and a limiting member 630. The claw body 610 is rotatably connected to the base plate 620, and the limiting member 630 restricts the rotation of the claw body 610. When the guide member 400 is in the first position 710, the limiting member 630 abuts against the claw body 610, so that the claw body 610 is connected to the filter element body 110, thereby realizing the installation of the filter element body 110. When the guide member 400 is in the second position 720, the limiting member 630 disengages from the claw body 610, so that the claw body 610 is disengaged from the filter element body 110, thereby realizing the disassembly of the filter element body 110.

[0065] In this embodiment, there are multiple claw bodies 610, which are spaced apart circumferentially along the base plate 620. Each claw body 610 is connected to the filter element body 110, thereby more firmly fixing the filter element body 110 to the claw assembly 600.

[0066] The claw body 610 is rotatably connected to the base plate 620, and the limiting member 630 restricts the rotation of the claw body 610. When the guide member 400 is in the first position 710, the limiting member 630 abuts against the claw body 610, and the limiting member 630 restricts the claw body 610 to the position where it is connected to the filter element body 110, thereby connecting the claw body 610 to the filter element body 110 and realizing the installation of the filter element body 110. When the guide member 400 is in the second position 720, the limiting member 630 disengages from the claw body 610, and the limiting member 630 no longer restricts the claw body 610 to the position where it is connected to the filter element body 110, thereby disengaging the claw body 610 from the filter element body 110 and realizing the disassembly of the filter element body 110.

[0067] The claw assembly 600 also includes a second elastic element 640, which is disposed between the base plate 620 and the filter element body 110. The contact surface between the claw body 610 and the filter element body 110 is not parallel to the direction of the elastic force of the second elastic element 640. When the filter element body 110 is connected to the claw body 610, the second elastic element 640 can apply an elastic force in the direction of the contact surface between the claw body 610 and the filter element body 110, so that the filter element body 110 can be more firmly connected to the housing 300.

[0068] The base plate 620 has a groove on its outer periphery, and the claw body is rotatably connected to the groove so that the claw body 610 can rotate toward or away from the filter element body 110. When the claw body 610 is close to the filter element body 110, the claw body 610 can connect with the filter element body 110; when the claw body 610 is away from the filter element body 110, the claw body 610 can detach from the filter element body 110.

[0069] The claw assembly 600 also includes an elastic part 650, which is located at the connection between the claw body 610 and the base plate 620. The elastic part 650 is used to provide a force for the claw body 610 to rotate away from the filter element body 110. Thus, when the claw body 610 is no longer restricted by the limiting member 630, the elastic part 650 can provide a force for the claw body 610 to rotate away from the filter element body 110, so that the claw body 610 can be separated from the filter element body 110 more quickly and the filter element body 110 can be disassembled more easily.

[0070] A limiting member 630 is sleeved on the outside of the claw body 610. The limiting member 630 has a through hole. One end of the guide member 400 is rotatably connected to the base plate 620, and the other end of the guide member 400 slides through the through hole in the guide groove 500. By providing a through hole in the limiting member 630 for the guide member 400 to pass through, one end of the guide member 400 can be connected to the base plate 620, and the other end of the guide member 400 can slide through the through hole in the guide groove 500, thereby preventing the limiting member 630 from obstructing the sliding of the guide member 400 in the guide groove 500.

[0071] like Figure 3 As shown, the guide member's motion streamline y is illustrated. The guide groove 500 includes a first guide groove 530 and a second guide groove 540. The first guide groove 530 guides the member 400 from a first position 710 to a second position 720, and the second guide groove 540 guides the member 400 from the second position 720 to the first position 710. When it is necessary to disassemble the filter element body 110, under the action of external force and the elastic force of the first elastic member 200, the guide member 400 slides within the first guide groove 530, and slides from the first position 710 to the second position 720, causing the claw body 610 to disengage from the filter element body 110, thereby causing the filter element body 110 to detach from the outer casing 300. When the filter element body 110 needs to be installed, under the action of external force and the elastic force of the first elastic member 200, the guide member 400 slides in the second guide groove 540, and the guide member 400 slides from the second position 720 to the first position 710, so that the claw body 610 connects to the filter element body 110, thereby connecting the filter element body 110 to the outer shell 300.

[0072] The first guide groove 530 includes a first part 531 and a second part 532, which are sequentially connected from the first position 710 to the second position 720. The first part 531 is configured such that when the filter body 110 is subjected to an external force, the guide member 400 can slide from the first part 531 to the second part 532. The second part 532 is configured such that under the elastic force of the first elastic member 200, the guide member 400 can slide from the second part 532 to the second position 720.

[0073] When the filter element body 110 is subjected to an external force, the guide member 400 can slide from the first part 531 to the second part 532. At the same time, the first elastic member 200 is compressed under the external force. Then, when the first elastic member 200 loses the external force, the elastic force of the first elastic member 200 is released. Under the elastic force of the first elastic member 200, the guide member 400 can slide from the second part 532 to the second position 720. The claw body 610 disengages from the filter element body 110, thereby causing the filter element body 110 to disengage from the outer shell 300.

[0074] The second guide groove 540 includes a third part 541 and a fourth part 542, which are sequentially connected from the second position 720 to the first position 710. The third part 541 is configured such that when the filter body 110 is subjected to an external force, the guide member 400 can slide from the third part 541 to the fourth part 542. The fourth part 542 is configured such that under the elastic force of the first elastic member 200, the guide member 400 can slide from the fourth part 542 to the first position 710.

[0075] When the filter element body 110 is subjected to an external force, the guide member 400 can slide from the third part 541 to the fourth part 542. At the same time, the first elastic member 200 is compressed under the external force. Then, when the first elastic member 200 loses the external force, the elastic force of the first elastic member 200 is released. Under the elastic force of the first elastic member 200, the guide member 400 can slide from the fourth part 542 to the first position 710. The claw body 610 is connected to the filter element body 110, thereby connecting the filter element body 110 to the outer shell 300.
