[0045] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the drawings are exemplary. The embodiments of the present invention will be described in detail below.

[0046] Reference will be made below to Figures 1 - 10 Describe the water purifier 100 provided according to an embodiment of the present invention.

[0047] As Figure 1 shown, the water purifier 100 according to an embodiment of the present invention may include: a filter element assembly 10, a mounting shell 20, and a filter seat 30. The filter element assembly 10 and the filter seat 30 are installed in the mounting shell 20, and the filter element assembly 10 and the filter seat 30 are communicated with each other to perform water inlet and outlet.

[0048] As Figure 1 shown, on one side of the filter element assembly 10 facing the filter seat 30, an inlet joint 11 and an outlet joint 12 are provided. The inlet joint 11 and the outlet joint 12 are cylindrical, and the inlet joint 11 and the outlet joint 12 protrude toward the filter seat 30. The inlet joint 11 and the outlet joint 12 are sleeved. For example, since the diameter of the inlet joint 11 is greater than the diameter of the outlet joint 12, and the interiors of the inlet joint 11 and the outlet joint 12 are hollow and conduct, the outlet joint 12 can be sleeved and installed in the internal space of the inlet joint 11. With such a setting, not only can the structure be more compact, but also the positions of water inlet and outlet are designed at the same place, which can avoid leakage at the water inlet and outlet positions, resulting in multiple leakage situations of the filter element assembly 10, facilitating the maintenance and management of the water purifier 100, optimizing the process design, and improving the user's adaptation and use experience.

[0049] As Figure 1As shown, the installation shell 20 may include: a first shell 21 and a second shell 22. The second shell 22 is disposed opposite to the first shell 21, and the second shell 22 is detachably mounted on the first shell 21. The installation shell 20 is generally in the shape of a cuboid, and the cuboid includes but is not limited to a cube. The second shell 22 and the first shell 21 define a chamber 23 for accommodating the filter element assembly 10. That is to say, the installation shell 20 may mainly include: the first shell 21 and the second shell 22. The first shell 21 and the second shell 22 are disposed opposite to each other. It should be noted that the cuboid includes but is not limited to a cube. The second shell 22 is detachably mounted on the first shell 21. After the second shell 22 and the first shell 21 are installed, the installation shell 20 is generally in the shape of a cuboid, and a relatively enclosed chamber 23 can be formed in the internal space of the installation shell 20. The filter element assembly 10 can be installed in the relatively enclosed chamber 23 inside the second shell 22 and the first shell 21. With such a setting, not only can the repair and replacement of the filter element assembly 10 be facilitated, the user experience can be improved, but also foreign objects from the outside can be prevented from entering the chamber 23 and damaging the filter element assembly 10. In addition, the relatively hard installation shell 20 can also protect the filter element assembly 10 when the water purifier 100 is impacted by an external force, avoiding damage to the filter element assembly 10 and increasing the service life of the water purifier 100. Moreover, the cuboid installation shell 20 can be suitable for installing the filter element assembly 10, making the overall structure of the filter element assembly 10 and the installation shell 20 small and compact, and further reducing the space occupied by the water purifier 100.

[0050] Further, as Figure 1 shown, both sides of the first shell 21 and the second shell 22 in the width direction of the installation shell 20 are mutually adapted arcs. In this way, the corners of the cuboid-shaped installation shell 20 can be all rounded. With such a setting, not only can the wear of each corner of the installation shell 20 be reduced, the service life of the water purifier 100 can be improved, but also the relatively blunt rounded corners can prevent the installation shell 20 from stabbing or scratching the user in case of an emergency, improving the user experience.

[0051] Combined with Figure 1 and Figure 8As shown, the filter base 30 is rotatably arranged in the first housing 21. The water inlet connector 11 and the water outlet connector 12 are respectively connected within the filter base 30. After the second housing 22 is detached from the first housing 21, the filter base 30 can rotate relative to the first housing 21 for the installation and disassembly of the filter element assembly 10. That is to say, the filter base 30 is installed on the first housing 21 and can rotate relative to the first housing 21. The water inlet connector 11 and the water outlet connector 12 protruding from one side of the filter element assembly 10 towards the filter base 30 are respectively installed and connected within the filter base 30, thereby realizing the connection and fixation of the entire filter element assembly 10 to the filter base 30. Further, when the filter element assembly 10 needs to be disassembled for repair or replacement, the second housing 22 can be first detached from the first housing 21, and then an outward force is applied to the side of the filter element assembly 10 away from the first housing 21, causing the filter element assembly 10 to drive the filter base 30 to rotate relative to the first housing 21. When the filter base 30 rotates to an appropriate angle, the filter element assembly 10 can be directly taken out, thus completing the disassembly of the filter element assembly 10. Such a setting not only makes it easier and more convenient for users to install and disassemble the filter element assembly 10, but also ensures the structural stability of the water purifier 100, preventing it from being too difficult for users to install or disassemble the filter element assembly 10 and avoiding damage to the structure of the water purifier 100 caused by excessive user force, thereby improving the user experience.

[0052] In addition, currently, the stress points of the filter element assembly 10 are mainly concentrated at the head of the filter element assembly 10, that is, at the water inlet connector 11 and the water outlet connector 12. The greater the supporting force received here, the greater the corresponding frictional force. The method of rotating and disassembling the filter element assembly 10 cleverly resolves this frictional force. When the user replaces the filter element assembly 10, with the action of a longer lever arm, only a relatively small force needs to be provided from the bottom of the filter element assembly 10. Therefore, the applied force is much smaller than the frictional force, and the filter element assembly 10 can be easily replaced.

[0053] Thus, for the water purifier 100 according to the present invention, by providing a rotatable filter base 30 and a detachable mounting shell 20, the installation and disassembly of the filter element assembly 10 can be facilitated, the replacement difficulty of the filter element assembly 10 can be reduced, and the user experience can be improved.

[0054] Combined with Figures 1 - 10As shown in the figure, the filter base 30 includes: a base body 31, a water inlet pipe 32, and a water outlet pipe 33. The water inlet pipe 32 and the water outlet pipe 33 are both arranged on the base body 31. The water inlet joint 11 and the water outlet joint 12 are respectively arranged inside the base body 31. The water inlet pipe 32 is communicated with the water inlet joint 11, and the water outlet pipe 33 is communicated with the water outlet joint 12. That is to say, the filter base 30 can mainly include: the base body 31, the water inlet pipe 32, and the water outlet pipe 33. The water inlet pipe 32 and the water outlet pipe 33 can be installed on the side of the base body 31 away from the filter element assembly 10. The water inlet joint 11 and the water outlet joint 12 are respectively installed inside the base body 31, and the water inlet pipe 32 is communicated with the water inlet joint 11, and the water outlet pipe 33 is communicated with the water outlet joint 12. Such a setting can not only ensure the independence of the operation of the filter base 30, prevent the filter base 30 from contacting other components during rotation, resulting in rotation jamming or damage to other components, but also avoid leakage at the connection ports of the water inlet pipe 32 and the water inlet joint 11 or the water outlet pipe 33 and the water outlet joint 12 of the water purifier 100, increase the reliability of the structure, and improve the user experience. Among them, the water inlet pipe 32 and the water outlet pipe 33 can be integrally formed with the base body 31, but this is not limited thereto. In this way, not only can the airtightness of the structure be further ensured to prevent leakage, but also the process difficulty can be reduced and the production can be simplified.

[0055] Combined with Figure 1 and Figure 2 As shown in the figure, the water purifier 100 further includes: a water inlet assembly 40 and a water outlet assembly 41. The water inlet assembly 40 and the water outlet assembly 41 are both arranged inside the installation shell 20. The water inlet pipe 32 and the water outlet pipe 33 extend in opposite directions on the filter base 30. The water inlet pipe 32 is rotatably arranged on the water inlet assembly 40, and the water outlet pipe 33 is rotatably arranged on the water outlet assembly 41. That is to say, the water purifier 100 can further mainly include: the water inlet assembly 40 and the water outlet assembly 41. The water inlet assembly 40 and the water outlet assembly 41 are both installed in the internal space of the installation shell 20. One end of the water inlet pipe 32 and the water outlet pipe 33 is installed on the base body 31, and the other ends of the water inlet pipe 32 and the water outlet pipe 33 extend in two opposite directions along the width direction of the installation shell 20. Further, one end of the water inlet pipe 32 extending outward from the base body 31 is connected to the water inlet assembly 40, and the water inlet pipe 32 can rotate relative to the water inlet assembly 40. One end of the water outlet pipe 33 extending outward from the base body 31 is connected to the water outlet assembly 41, and the water outlet pipe 33 can rotate relative to the water outlet assembly 41. Such a setting can not only make full use of the available space inside the installation shell 20 to make the structure design more reasonable, but also ensure that the water inlet process and the water outlet process of the water purifier 100 do not interfere with each other, and can improve the reliability of the structure of the water purifier 100.

[0056] Combined with Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the filter base 30 has an initial position relative to the mounting shell 20. When the filter base 30 is in the initial position, the water inlet waterway is connected to the water inlet pipe 32 and the water outlet waterway is connected to the water outlet pipe 33. After the filter base 30 rotates relative to the mounting shell 20, the water inlet waterway is disconnected from the water inlet pipe 32 and the water outlet waterway is disconnected from the water outlet pipe 33. Specifically, the filter base 30 has an initial position relative to the mounting shell 20. When the filter base 30 is in the initial position, the water purifier 100 is in a normal working state. At this time, the water inlet waterway is in a connected state with the water inlet pipe 32, and the water outlet waterway is in a connected state with the water outlet pipe 33. At this time, the entire waterway in the water purifier 100 is in a normal flowing working state. Correspondingly, after the filter base 30 rotates relative to the mounting shell 20, that is to say, when the filter base 30 leaves the initial position relative to the mounting shell 20, the water inlet waterway is in a disconnected state from the water inlet pipe 32, and the water outlet waterway is in a disconnected state from the water outlet pipe 33. At this time, the entire waterway of the water purifier 100 is in a blocked state, and the water purifier 100 stops normal operation. Among them, the filter base 30 leaving the initial position may be because the filter element assembly 10 connected to the filter base 30 needs to be taken out for replacement and repair. With such a setting, when the filter element assembly 10 rotates to a suitable angle and can be easily taken out, the waterway of the water purifier 100 has been blocked, preventing water leakage at the connection position between the filter base 30 and the filter element assembly 10 when the filter element assembly 10 is taken out, which can optimize the process design and improve the user experience.

[0057] As Figure 1 shown, further, a water inlet seal ring 50 is sleeved between the end of the water inlet pipe 32 and the end of the water inlet assembly 40; a water outlet seal ring 51 is sleeved between the end of the water outlet pipe 33 and the end of the water outlet assembly 41. For example, since the end of the water inlet pipe 32 extending outward is slightly smaller in diameter than the end of the water inlet assembly 40 near one end of the water inlet pipe 32, a water inlet seal ring 50 can be sleeved between the ends of the water inlet pipe 32 and the water inlet assembly 40 sleeved and connected. Similarly, since the end of the water outlet pipe 33 extending outward is slightly smaller in diameter than the end of the water outlet assembly 41 near one end of the water outlet pipe 33, a water outlet seal ring 51 can be sleeved between the ends of the water outlet pipe 33 and the water outlet assembly 41 sleeved and connected. The water inlet seal ring 50 and the water outlet seal ring 51 can both be made of rubber material with good antioxidant performance and acid and alkali resistance. With such a setting, not only can the firmness and stability of the sleeved connection between the water inlet pipe 32 and the water inlet assembly 40 or the water outlet pipe 33 and the water outlet assembly 41 be further improved, preventing the sleeved connection from falling off and enhancing the reliability of the structure, but also the tightness between the water inlet pipe 32 and the water inlet assembly 40 or the water outlet pipe 33 and the water outlet assembly 41 can be improved, preventing water leakage during water inlet or outlet, and improving the user experience.

[0058] Further, asFigure 1 As shown, both the water inlet sealing ring 50 and the water outlet sealing ring 51 include: a first annular portion 52, a second annular portion 53, and a connecting portion 54. The first annular portion 52 and the second annular portion 53 are arranged at intervals. There are multiple connecting portions 54 which are respectively connected between the first annular portion 52 and the second annular portion 53. The water inlet sealing ring 50 is integrally sleeved on the end of the water inlet pipe 32, and the water outlet sealing ring 51 is integrally sleeved on the end of the water outlet pipe 33. That is to say, both the water inlet sealing ring 50 and the water outlet sealing ring 51 can mainly include: a first annular portion 52, a second annular portion 53, and a connecting portion 54. The first annular portion 52 and the second annular portion 53 are of the same size, and the first annular portion 52 and the second annular portion 53 are arranged at intervals. The connecting portion 54 can connect the first annular portion 52 and the second annular portion 53, and the length of the connecting portion 54 is the interval distance between the first annular portion 52 and the second annular portion 53. Further, there are multiple connecting portions 54. Such a setting can not only improve the sealing performance of the sealing ring, but also further improve the firmness and stability of the sleeved connection between the water inlet pipe 32 and the water inlet assembly 40 or between the water outlet pipe 33 and the water outlet assembly 41.

[0059] Combined with Figure 1 As shown, grooves 34 are provided at the ends of both the water inlet pipe 32 and the water outlet pipe 33. At least a part of the first annular portion 52, the connecting portion 54, and the second annular portion 53 is received in the grooves 34. That is to say, grooves 34 are provided at the ends of the outwardly extending ends of the water inlet pipe 32 and the water outlet pipe 33, and at least a part of the first annular portion 52, the connecting portion 54, and the second annular portion 53 is installed in the grooves 34. In this way, the sealing ring can be more firmly sleeved on the water inlet pipe 32 or the water outlet pipe 33, preventing the sealing ring from displacing on the water inlet pipe 32 or the water outlet pipe 33 in a humid environment, and increasing the structural stability.

[0060] Combined with Figures 2 - 4As shown, after the filter base 30 rotates relative to the first housing 21, the water path between the water inlet pipe 32 and the water inlet assembly 40 is disconnected, and the water path between the water outlet pipe 33 and the water outlet assembly 41 is disconnected. That is to say, when replacing and repairing the filter element 15, an outward force is applied to the side of the filter element assembly 10 away from the first housing 21, so that the filter element assembly 10 drives the filter base 30 to rotate relative to the first housing 21. When the filter base 30 rotates relative to the first housing 21 to an appropriate angle and the filter element assembly 10 can be directly removed, the water path between the water inlet pipe 32 and the water inlet assembly 40 is disconnected, and the water path between the water outlet pipe 33 and the water outlet assembly 41 is disconnected. The water path of the entire water purifier 100 is blocked. Such a setting can not only prevent water leakage when the filter element assembly 10 is taken out, which affects the user experience, but also has a certain anti-mistake function. Before the filter base 30 rotates relative to the first housing 21 to an appropriate angle and the filter element assembly 10 can be directly removed, the water path has been automatically disconnected, and there is no need to perform other operations to disconnect the water path. This can improve the process design, reduce the user's operation steps, and enhance the user experience.

[0061] Therefore, for the water purifier 100 according to the present invention, by means of the rotation of the filter base 30, not only can the installation and disassembly of the filter element assembly 10 be facilitated, but also the water path can be cut off before its installation and disassembly, which can avoid water leakage, reduce the user's operation steps, and enhance the user experience.

[0062] Combined with Figures 1 - 4 As shown, both the water inlet assembly 40 and the water outlet assembly 41 include: a connecting pipe section and a docking head 45. The water inlet water path or the water outlet water path is formed in the connecting pipe section. The docking head 45 is connected to one end of the connecting pipe section. The water inlet pipe 32 or the water outlet pipe 33 has a docking hole 46 for docking with the connecting pipe section and is rotatably arranged on the docking head 45 to be disconnected from the connecting pipe section after the water inlet pipe 32 rotates relative to the docking head 45. That is to say, both the water inlet assembly 40 and the water outlet assembly 41 mainly include: a connecting pipe section and a docking head 45. The water inlet water path or the water outlet water path is formed and flows in the connecting pipe section. The docking head is connected and installed at one end of the connecting pipe section, and one end of the docking head corresponds to the water inlet pipe 32 or the water outlet pipe 33. The water inlet pipe 32 or the water outlet pipe 33 is designed with a docking hole 46, which can be used for connecting and installing with the corresponding end of the connecting pipe section. And the water inlet pipe 32 or the water outlet pipe 33 can rotate relative to the docking head 45. After the water inlet pipe 32 or the water outlet pipe 33 rotates relative to the docking head 45, the connection between the water inlet pipe 32 or the water outlet pipe 33 and the connecting pipe section is disconnected, and the water path of the water purifier 100 is blocked. Such a setting can optimize the structural design, make the water stop of the water purifier 100 more reliable and less prone to mistakes, and enhance the user experience.

[0063] Specifically, the connecting pipe section includes: a first pipe section 42, a second pipe section 43, and a third pipe section 44. The first pipe section 42 is vertically arranged and communicated with the second pipe section 43. The third pipe section 44 is vertically arranged and communicated with the second pipe section 43. The docking head 45 is communicated with the third pipe section 44. The water inlet pipe 32 or the water outlet pipe 33 has a docking hole 46 for docking with the third pipe section 44, so as to disconnect from the third pipe section 44 after the water inlet pipe 32 rotates relative to the docking head 45. That is to say, since the connecting pipe section can mainly include: the first pipe section 42, the second pipe section 43, and the third pipe section 44, both the water inlet assembly 40 and the water outlet assembly 41 can mainly include: the first pipe section 42, the second pipe section 43, the third pipe section 44, and the docking head 45. The first pipe section 42 is vertically installed on the second pipe section 43, and the third pipe section 44 is installed and connected to one end of the second pipe section 43 close to the filter base 30. The third pipe section 44 is perpendicular to the second pipe section 43. That is to say, the second pipe section 43 is parallel to the water inlet pipe 32 or the water outlet pipe 33, and the first pipe section 42 and the third pipe section 44 are perpendicular to the water inlet pipe 32 or the water outlet pipe 33. Among them, the third pipe section 44 is close to the water inlet pipe 32 or the water outlet pipe 33, and the first pipe section 42 is far from the water inlet pipe 32 or the water outlet pipe 33. The first pipe section 42 is communicated with the second pipe section 43, and the second pipe section 43 is communicated with the third pipe section 44, jointly completing the water flow work of the water purifier 100. Such a setting can not only make full use of the internal space of the installation shell 20, avoid designing the size of the installation shell 20 too large, but also make the water flow channel relatively simple and compact, ensure the water pressure and flow rate, and improve the user experience.

[0064] Among them, as shown in combination with Figure 1 and Figure 3 , the docking head 45 is communicated with the third pipe section 44. The docking head 45 and the water inlet pipe 32 or the water outlet pipe 33 are flush with each other at the same height, which can facilitate the sleeving connection between the docking head 45 and the water inlet pipe 32 or the water outlet pipe 33. In addition, the water inlet pipe 32 or the water outlet pipe 33 is provided with a docking hole 46. The docking hole 46 can be docked with the third pipe section 44, and the docking hole 46 can rotate with the rotation of the water inlet pipe 32 or the water outlet pipe 33 relative to the docking head 45. Specifically, when the water purifier 100 is in a normal working state, the docking hole 46 is located in the docking head 45 and is conducted with the third pipe section 44. The water coming out of the third pipe section 44 enters the water inlet pipe 32 or the water outlet pipe 33 through the docking hole 46, so as to make the entire water path unobstructed.

[0065] As shown in combination with Figure 1 and Figure 4As shown, when the filter element assembly 10 of the water purifier 100 needs to be replaced or repaired, the filter element assembly 10 is rotated to an appropriate angle, and the filter seat 30 rotates following the rotation of the filter element assembly 10, thereby causing the water inlet pipe 32 or the water outlet pipe 33 on the filter seat 30 to rotate, and further rotating the docking hole 46 on the water inlet pipe 32 or the water outlet pipe 33 to a position where it cannot be docked and conducted with the third pipe section 44, so as to block the outward water flow of the third pipe section 44, and finally achieve the purpose of closing the water circuit. The entire process only needs to rotate the filter element assembly 10 to achieve the two purposes of closing the water circuit and being able to easily remove the filter element assembly 10, which can optimize the structural design and improve the user experience.

[0066] Optionally, in combination Figure 1 As shown, the water purifier 100 may further include: a base 60, the base 60 is disposed on the first housing 21, the filter seat 30 is disposed inside the base 60, the base 60 is formed with a support groove 61 for supporting the water inlet pipe 32 and the water outlet pipe 33, and the water inlet pipe 32 and the water outlet pipe 33 are rotatable relative to the support groove 61. Specifically, the water purifier 100 may mainly further include: a base 60, the installation position of the base 60 is on the first housing 21, the installation position of the filter seat 30 is in the internal space of the base 60, and a support groove 61 is designed on each of the two opposite sides of the base 60 relative to the first housing 21 to support the water inlet pipe 32 and the water outlet pipe 33, and the water inlet pipe 32 and the water outlet pipe 33 can rotate relative to the support groove 61. With such a setting, the base 60 can not only effectively protect the filter seat 30 and extend the life of the filter seat 30, but also the internal space of the base 60 can ensure that the filter seat 30 is not affected or interrupted by other components during the rotation process, which can ensure the independence and rationality of the structure and optimize the process structure.

[0067] In combination Figures 1 - 2 As shown, the base 60 is provided with a first limiting groove 62 that opens towards the second housing 22, the seat body 31 is provided with a second limiting groove 63 that opens towards the bottom, and the filter element assembly 10 further includes: a limiting post 13, the limiting post 13 is disposed on at least one side of the water inlet joint 11, and the limiting post 13 is fitted in the first limiting groove 62 and the second limiting groove 63. Further, a first limiting groove 62 is designed on each of the two opposite sides of the base 60 relative to the first housing 21, and the two first limiting grooves 62 open towards the second housing 22. The seat body 31 of the filter seat 30 is designed with a second limiting groove 63 below the two opposite sides relative to the first housing 21. The filter element assembly 10 may mainly further include: a limiting post 13, the limiting post 13 is installed on the water inlet joint 11 of the filter element assembly 10, and the limiting post 13 can be engaged with the first limiting groove 62 and the second limiting groove 63.

[0068] Specifically, in combination Figure 1 、 Figure 6 、 Figure 7 、Figure 8 and Figure 9 As shown in Figure 9 , when the water purifier 100 is in a normal working state, the limit post 13 is engaged with the first limit groove 62 and the second limit groove 63. It can be understood that the first limit groove 62 can limit the freedom of movement of the limit post 13 in the up and down direction, so that the filter element assembly 10 is fixed in the up and down direction. The second limit groove 63 can limit the freedom of movement of the limit post 13 in the left and right direction, so that the filter element assembly 10 is fixed in the left and right direction. This can ensure the stable operation of the filter element assembly 10 and prevent the position of the filter element assembly 10 from moving when the water purifier 100 is subjected to an external impact, resulting in damage to the structure of the water purifier 100 and causing the water purifier 100 to fail to work properly, thereby improving the reliability of the structure. Among them, since the installation shell 20 is a cuboid, the height direction of the cuboid is the up and down direction, and the width direction of the cuboid is the left and right direction.

[0069] Correspondingly, as shown in Figures 5 - 9 Figures 5 - 9 , when the filter element assembly 10 of the water purifier 100 needs to be repaired or replaced, the filter element assembly 10 needs to be taken out of the installation shell 20 first. At this time, since the first limit groove 62 and the second limit groove 63 cannot limit the rotational freedom of the limit post 13, a force can be applied to the filter element assembly 10 to rotate the filter element assembly 10 and the filter base 30 outwards as a whole, so that the filter element assembly 10 is disengaged from the restriction of the first limit groove. At this time, as the angle rotates, the second limit groove 63 becomes capable of restricting the freedom of movement of the limit post 13 in the up and down direction, and the freedom of movement of the limit post 13 in the left and right direction cannot be restricted. Therefore, applying a relatively rightward force to the filter element assembly 10 can easily take out the filter element assembly 10. With such a setting, not only can the structure of the water purifier 100 be designed more cleverly, the filter element assembly 10 can be made more convenient and easier to repair and replace, the user experience can be improved, but also it can prevent damage to the structure of the water purifier 100 when the user takes out the filter element assembly 10 with too much force, and the process structure can be optimized.

[0070] Alternatively, a limit groove is provided on the second housing 22. The filter element assembly 10 further includes: a limit post 13, which is provided on at least one side of the water inlet joint 11, and the limit post 13 is in limit cooperation with the limit groove. That is to say, a limit groove is installed on the second housing 22. The filter element assembly 10 can further include: a limit post 13, which is installed on one side of the water inlet joint 11, and the limit post 13 can be in limit cooperation with the limit groove, which can further make the installation of the filter element assembly 10 more firm, make the force on the filter element assembly 10 more uniform, and optimize the process structure.

[0071] In another alternative, the bottom of the first housing 21 is abutted against the bottom of the filter element assembly 10. Specifically, an abutting portion is installed at the bottom of the first housing 21, so that the bottom of the filter element assembly 10 can abut against the bottom of the first housing 21, which can prevent the filter element assembly 10 from being acted upon by an external force and the limit column 13 from being pulled downward by the external force. The abutting position can provide an upward interaction force to the filter element assembly 10, which in turn offsets the downward force and avoids damage to the limit column 13, thereby increasing the reliability of the structure and improving the service life of the water purifier 100.

[0072] Combination Figure 1 and Figure 5 As shown, the bottom of the first housing 21 is provided with an abutment platform 70 protruding toward the bottom of the filter element assembly 10. Specifically, the abutment portion installed at the bottom of the first housing 21 is the abutment platform 70, which is installed at the bottom of the first housing 21 and protrudes toward one side of the filter element assembly 10, and is used to abut the filter element assembly 10, so that the installation of the filter element assembly 10 can be more firmly set, and the abutment platform 70 can make the force of the filter element assembly 10 more uniform, and can make a certain gap between the filter element assembly 10 and the bottom of the first housing 21. The user inserts his fingers into the gap position and pries the filter element assembly 10 outward to rotate it to a suitable position, which can facilitate the user to exert force and improve the user's experience.

[0073] In another optional embodiment, the first housing 21 is provided with a first limiting portion 71, and the filter element assembly 10 is provided with a second limiting portion, and the first limiting portion 71 and the second limiting portion cooperate in limiting manner. Specifically, the first housing 21 is designed with a first limiting portion 71, and there are multiple first limiting portions 71 and the first limiting portions 71 are evenly distributed on the first housing 21, and the filter element assembly 10 is designed with a second limiting portion at a position corresponding to the first limiting portion 71, and there are multiple second limiting portions and the second limiting portions are evenly distributed on the second housing 22, and multiple first limiting portions 71 cooperate with multiple second limiting portions in a one-to-one correspondence, which can further make the filter element assembly 10 installed more firmly and stably inside the mounting shell 20.

[0074] Among them, one of the first limiting portion 71 and the second limiting portion is a buckle, and the other of the first limiting portion 71 and the second limiting portion is a slot. When the filter element assembly 10 is installed inside the mounting shell 20, the buckle and the slot are engaged with each other, thereby completing the mutual cooperation between the first limiting portion 71 and the second limiting portion, so that the filter element assembly 10 is more firmly installed on the first shell 21. Such a setting can further increase the reliability of the structure without increasing the operating steps.

[0075] Alternatively, one of the first limiting portion 71 and the second limiting portion is a protrusion, and the other of the first limiting portion 71 and the second limiting portion is a recess, and the recess is a limiting groove. When the filter element assembly 10 is installed inside the installation shell 20, the protrusion extends into the recess, thereby completing the mutual cooperation between the first limiting portion 71 and the second limiting portion, and making the filter element assembly 10 more firmly installed on the first housing 21. With such a setting, the reliability of the structure can be further increased without increasing the operation steps. In addition, designing multiple cooperation methods can generate different hand feelings when installing or disassembling the filter element assembly 20, making the product more diversified, meeting the preferences of different users, and promoting the popularization of the water purifier 100.

[0076] In addition, at least one of the first housing 21 and the second housing 22 is provided with a limiting portion for limiting the filter element assembly 10. That is to say, at least one of the first housing 21 and the second housing 22 is installed with a limiting portion for limiting the filter element assembly 10. With such a setting, the firmness of the installation of the filter element assembly 10 inside the installation shell 20 can be further increased, and the filter element assembly 10 can be further prevented from moving inside the installation shell 20, resulting in the abnormal operation of the water purifier 100, and the service life of the water purifier 100 can be improved.

[0077] Among them, the first limiting portion 71 is a limiting plate, and the limiting plates are distributed at both ends in the width direction of the first housing 21 to limit both ends in the width direction of the filter element assembly 10. That is to say, the first limiting portion 71 can be designed as a limiting plate, and the limiting plates are installed at both ends in the width direction of the first housing 21 and are symmetrically distributed at both ends in the width direction of the first housing 21 to limit both ends in the width direction of the filter element assembly 10. On the basis that the bottom and top of the filter element assembly 10 have been limited, the two sides of the filter element assembly 10 in the width direction can be further limited, so that the filter element assembly 10 can be further limited in all directions, preventing the filter element assembly 10 from shifting inside the installation shell 20 and affecting the normal operation of the water purifier 100, and the service life of the water purifier 100 can be improved.

[0078] Combined with Figures 1 - 10As shown in the figure, a partition plate 73 is provided on the first housing 21. The partition plate 73 divides the installation housing 20 into a first chamber 24 and a second chamber 25. The first chamber 24 is used to accommodate the main structure of the filter element assembly 10, and the second chamber 25 is used to accommodate the filter base 30, the water inlet joint 11, and the water outlet joint 12. That is to say, the partition plate 73 is installed on the first housing 21. The partition plate 73 can divide the chamber 23 of the internal space of the installation housing 20 into a first chamber 24 and a second chamber 25. The first chamber 24 can be used to accommodate the main structure of the filter element assembly 10, and the second chamber 25 can be used to accommodate the filter base 30, the water inlet joint 11, and the water outlet joint 12. With such a setting, not only can the independence of the components of the water purifier 100 be ensured, avoiding the mutual influence of the components of the water purifier 100 during operation, but also the structural reliability of the water purifier 100 can be increased.

[0079] Furthermore, as Figure 1 shown, a part of the partition plate 73 is configured as a limiting plate portion 74. The limiting plate portion 74 can be in limiting cooperation with the limiting plate portion 74 after the filter element assembly 10 rotates a predetermined angle relative to the first housing 21. That is to say, a part of the partition plate 73 is the limiting plate portion 74. Specifically, after the filter element assembly 10 rotates relative to the first housing 21 to an appropriate angle at which the filter element assembly 10 can be directly taken out, the limiting plate portion 74 can limit the further rotation of the filter element assembly 10. With such a setting, it has a certain anti-mistake effect. When the user rotates the filter element assembly 10 to a position where it can be in limiting cooperation with the limiting plate portion 74, the rotation angle at this time is exactly the appropriate angle at which the filter element assembly 10 can be easily taken out, which can avoid the filter element assembly 10 from not being taken out due to too small or too large a rotation angle. And the user does not need to observe the rotation angle to adjust the magnitude of the applied force and the time when the force stops to achieve the purpose of rotating the filter element assembly 10 to an appropriate angle, which can improve the user experience. The predetermined angle can be 30° - 75°. Further, the predetermined angle can be 45° - 48°.

[0080] Combined with Figures 1 - 10 shown, the installation housing 20 may mainly further include: a top cover 76. The first housing 21 is integrally formed with the bottom of the first housing 21, and the top of the first housing 21 is in an open state. The top cover 76 is covered and fixed on the top of the first housing 21. When the components in the second chamber 25 are damaged and need to be repaired and replaced, the top cover 76 can be directly opened to replace the components in the second chamber 25. With such a setting, the components in the second chamber 25 can be replaced without disassembling the first housing 21 and the second housing 22, which can optimize the process flow and improve the user experience.

[0081] Furthermore, combined with Figures 1 - 10As shown, a connecting plate 75 is designed between the first housing 21 and the partition plate 73. The connecting plate 75 can connect the first housing 21 and the partition plate 73, and the connecting plate 75 divides the second chamber 25 into three regions. One region is for installing the water inlet assembly 40, one region is for installing the water outlet assembly 41, and the other region is for installing the filter base 30, the water inlet joint 11 and the water outlet joint 12. With such a setting, not only can the connection between the partition plate 73 and the first housing 21 be made more stable and firm, but also the independence of the operation of each component in the second chamber 25 can be further increased, so that the operations of each component do not affect each other, thereby further increasing the reliability of the structure of the water purifier 100.

[0082] Combined with Figure 10 As shown, the filter element assembly 10 includes: a filter cartridge 14 and a plurality of filter elements 15. The filter cartridge 14 defines a plurality of accommodating cavities 16. The axial direction of the plurality of accommodating cavities 16 is the first direction, and the spacing direction is the second direction. The first direction is perpendicular to the second direction. The plurality of filter elements 15 are respectively arranged in the plurality of accommodating cavities 16. That is to say, the filter element assembly 10 mainly includes: a filter cartridge 14 and a plurality of filter elements 15. The inside of the filter cartridge 14 defines a plurality of accommodating cavities 16. The axial direction of the plurality of accommodating cavities 16 is the first direction, and the spacing direction of the plurality of accommodating cavities 16 is the second direction. The first direction is perpendicular to the second direction. The plurality of filter elements 15 are installed in one-to-one correspondence with the plurality of accommodating cavities 16. With such a setting, the filter element 15 can be further isolated from the outside world to prevent foreign objects from entering and damaging the filter element 15. In addition, by designing a plurality of accommodating cavities 16, the plurality of filter elements 15 with different filtering effects can be placed separately. When a certain filter element 15 needs to be replaced, only the filter element 15 that needs to be replaced needs to be replaced, avoiding unnecessary waste caused by overall replacement. Among them, after the filter element assembly 10 is installed inside the installation shell 20, the first direction is the height direction of the installation shell 20, that is, the up and down direction, and the second direction is the length direction of the installation shell 20. The filter element assembly 10 configured in this way is in the shape of a cuboid, which is a flat structure with a small volume, convenient for installation and layout, and can also correspond well to the installation shell 20.
