Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.

A water purifier 100 provided according to an embodiment of the present invention will be described with reference to fig. 1 to 10.

As shown in fig. 1, a water purifier 100 according to an embodiment of the present invention may include: the filter element assembly 10, the mounting shell 20 and the filter base 30, the filter element assembly 10 and the filter base 30 are mounted in the mounting shell 20, and the filter element assembly 10 and the filter base 30 are communicated with each other for water inlet and outlet.

As shown in FIG. 1, a water inlet joint 11 and a water outlet joint 12 are arranged on one side of the filter element assembly 10 facing to the filter base 30, the water inlet joint 11 and the water outlet joint 12 are in a cylindrical shape, and the water inlet joint 11 and the water outlet joint 12 are protruded toward one side of the filter base 30, and the water inlet joint 11 and the water outlet joint 12 are sleeved, for example, because the diameter of the water inlet joint 11 is larger than that of the water outlet joint 12, and the interiors of the water inlet joint 11 and the water outlet joint 12 are hollow and are communicated, the water outlet joint 12 can be sleeved in the inner space of the water inlet joint 11, so that the structure is more compact, moreover, the water inlet and outlet positions are designed at the same position, so that the condition that the filter element component 10 leaks from multiple positions due to the leakage of the water inlet and outlet positions can be avoided, the water purifier 100 is convenient to maintain and manage, the process design can be optimized, and the adaptive use experience of a user can be improved.

As shown in fig. 1, the mounting case 20 may include: the filter cartridge assembly comprises a first shell 21 and a second shell 22, wherein the second shell 22 is arranged opposite to the first shell 21, the second shell 22 is detachably mounted on the first shell 21, the mounting shell 20 is integrally in a cuboid shape, the cuboid comprises but is not limited to a square, and the second shell 22 and the first shell 21 define a cavity 23 for accommodating the filter cartridge assembly 10. That is, the mounting case 20 may mainly include: the filter element assembly comprises a first shell 21 and a second shell 22, the first shell 21 and the second shell 22 are arranged oppositely, it should be noted that the cuboid includes but is not limited to a cube, the second shell 22 is detachably installed on the first shell 21, the installation shell 20 is integrally cuboid after the second shell 22 and the first shell 21 are installed, a relatively closed cavity 23 can be formed in the internal space of the installation shell 20, the filter element assembly 10 can be installed in the relatively closed cavity 23 inside the second shell 22 and the first shell 21, by such an arrangement, not only the maintenance and replacement of the filter element assembly 10 can be facilitated, the use experience of a user can be improved, but also external foreign objects can be prevented from entering the cavity 23 and damaging the filter element assembly 10, in addition, the installation shell 20 with relatively hard texture can also play a role in protecting the filter element assembly 10 when the water purifier 100 is impacted by external force, damage to the filter element assembly 10 is avoided and the service life of the water purifier 100 can be increased. In addition, the installation case 20 of the rectangular parallelepiped may be adapted to install the filter element assembly 10, so that the overall structure of the filter element assembly 10 and the installation case 20 is small and small, and the volume is small, thereby further reducing the space occupied in the water purifier 100.

Further, as shown in fig. 1, two sides of the first casing 21 and the second casing 22 in the width direction of the installation casing 20 are arcs matched with each other, so that corners of the rectangular installation casing 20 can be rounded, and the arrangement can reduce abrasion at each corner of the installation casing 20, prolong the service life of the water purifier 100, and prevent sudden occurrence of the obtuse rounded corner, the installation casing 20 stabs or scratches a user, thereby improving the user experience.

Referring to fig. 1 and 8, the filter base 30 is rotatably disposed in the first housing 21, the water inlet connector 11 and the water outlet connector 12 are respectively connected to the filter base 30, and after the second housing 22 is disassembled with respect to the first housing 21, the filter base 30 is rotatable with respect to the first housing 21, so as to assemble and disassemble the filter element assembly 10. That is, the filter base 30 is installed on the first housing 21, and the filter base 30 can rotate relative to the first housing 21, the water inlet connector 11 and the water outlet connector 12, which are convexly arranged on one side of the filter base 10 facing the filter base 30, are respectively installed and connected in the filter base 30, so as to realize the connection and fixation of the whole filter base 10 and the filter base 30, further, when the filter base 10 needs to be disassembled for maintenance or replacement, the second housing 22 can be disassembled relative to the first housing 21 first, then an outward force is applied to one side of the filter base 10 far away from the first housing 21, so that the filter base 10 drives the filter base 30 to rotate relative to the first housing 21, when the filter base 30 rotates to a proper angle, the filter base 10 can be directly taken out, thereby completing the disassembly of the filter base 10, and by such arrangement, a user can disassemble the filter base 10 more easily and conveniently, and also can guarantee the stability of water purifier 100 structure, prevent that the user from being too difficult when installation or dismantlement filter element group spare 10, avoid the user to exert oneself too big damage that leads to water purifier 100 structure to can promote user's use and experience.

In addition, the stress point of the filter element assembly 10 is mainly concentrated at the head of the filter element assembly 10 at present, namely, the water inlet joint 11 and the water outlet joint 12 are positioned, the larger the supporting force received at the position is, the larger the corresponding friction force is, the friction force is ingeniously solved by rotating the mode of disassembling the filter element assembly 10, when the filter element assembly 10 is replaced by a user, under the action of a longer force arm, only a lighter force is required to be provided from the bottom of the filter element assembly 10, so the applied force is far smaller than the friction force, and the filter element assembly 10 can be easily replaced.

Therefore, according to the water purifier 100 of the present invention, the rotatable filter base 30 and the detachable mounting shell 20 are provided, so that the mounting and dismounting 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.

As shown in fig. 1 to 10, the filter base 30 includes: the water inlet pipe 32 is communicated with the water inlet connector 11, and the water outlet pipe 33 is communicated with the water outlet connector 12. That is, the filter base 30 may mainly include: the base 31, inlet tube 32 and outlet pipe 33 can install and set up in the one side that filter element group spare 10 was kept away from to base 31, water supply connector 11 and water connectors 12 install respectively and set up in base 31, and inlet tube 32 and water supply connector 11 are linked together, outlet pipe 33 with be linked together with water connectors 12, the independence of straining the work of base 30 not only can be guaranteed in so setting up, prevent to strain base 30 and contact other parts at the pivoted in-process and lead to the damage of pivoted card dun or other parts, and can avoid water purifier 100 to take place to leak at inlet tube 32 and water connectors 11 or outlet pipe 33 and the connection port department of water connectors 12, can increase the reliability of structure, can promote user's use and experience. The water inlet pipe 32 and the water outlet pipe 33 can be integrally manufactured with the base body 31, but not limited thereto, so that the tightness of the structure can be further ensured, leakage is prevented, the process difficulty can be reduced, and the production is simplified.
