When changing the filter core, open outer bottle 2, take off coarse filtration end cover 44 again, alright conveniently demolish coarse filtration subassembly 4 and inner bottle body 1, rotate inner bottle body 1 after that, inner bottle body 1 is dismantled in outer bottle body 2, from this alright conveniently demolish taste filter assembly 31 in inner bottle body 1, the smart filter assembly 33 of a smart filter assembly 32 and secondary, it is obvious, the improvement of outer bottle body 2 and inner bottle body 1 structure, and coarse filtration subassembly 4, remove taste filter assembly 31, the improvement of the smart filter assembly 32 of a smart filter assembly 32 and the smart filter assembly 33 overall arrangement mode of secondary, convenience of customers changes the filter core as required, realize that the dismantlement degree of difficulty of each filter core reduces, thereby promote the dismantlement convenience of filter core, and then promote user's use experience.

The utility model discloses still provide the second kind of embodiment, compare in first embodiment, the difference of the second kind of embodiment lies in the installation order between adjustment taste filtering component 31, the fine filtering component 32 of once and the fine filtering component 33 of secondary. In the second embodiment, the secondary fine filtering component 33 is disposed between the primary fine filtering component 32 and the mouth feel filtering component 31, that is, the primary fine filtering component 32, the secondary fine filtering component 33 and the mouth feel filtering component 31 are arranged in the axial direction of the inner bottle body 1 in the up-down manner, and accordingly, the filtrate channels between the primary fine filtering component 32, the secondary fine filtering component 33 and the mouth feel filtering component 31 are correspondingly adjusted accordingly, so as to ensure that various fine filtering water and filtering waste water smoothly circulate and are isolated from each other.

During the filtration, coarse filtration water is by the fine filtering component 32 of inner bottle body 1 inflow, generate fine filtration water and fine filtration waste water once after fine filtering component 32 filters once, fine filtration waste water directly flows into fine filtering component 33 of secondary once, generate fine filtration water of secondary after fine filtering component 33 filters twice, fine filtration water of secondary directly flows into in taste filtering component 31, of course, fine filtration water also can flow into in taste filtering component 31 once, make taste filtering component 31 carry out the taste to fine filtration water of fine filtration water and secondary once and filter, can make fine filtration waste water realize recycle once equally, avoid directly discharging fine filtration waste water once, therefore the composite filter core that this implementation provided also can promote water resource utilization and filtration efficiency.

The utility model also provides a water purifier, including above-mentioned composite filter element, have the same beneficial effect.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
