The base has a recessed groove disposed below a middle thereof for accommodating the winnower, two air inlet passages shaped with frame-shaped structures and disposed on two sides of the recessed groove respectively, and an integrated air exit disposed at a top thereof and corresponding to the winnower air exit of the winnower, wherein the integrated air exit is tightly connected to the winnower air exit of the winnower by the windshield. The back shell is disposed at a bottom of the base to position the winnower in the recessed groove and seal bottoms of the two air inlet passages. The two air inlet filters are respectively inserted into exits of the two air inlet passages and corresponding to the two winnower air entrances. The filter cartridge container is disposed on the winnower air exit of the winnower. The front shell is disposed at the top of the base to release filtered air.
Preferentially, the base is disposed with plural hooks on the top thereof, and the front shell is provided with a fixed frame shaped with a hollow portion in a middle thereof for detachably connecting to the base by clasping the plural hooks and a LED illumination element therein. Moreover, the front shell is provided with a light cover engaged with a top of the fixed frame, and an air outlet net is correspondingly disposed on the hollow portion of the fixed frame.
Preferentially, the front shell is further provided with an air quality indicating unit, and the air quality indicating unit is accommodated inside the fixed frame.
Preferentially, the filter cartridge container detachably connects to the winnower air exit of the winnower by plural elastic hooks.
Preferentially, the fixed frame is made of a plastic material.
Preferentially, the air outlet net is made of an iron material.
Preferentially, the light cover is made of a translucent plastic material.
The advantages of the present invention include:
1. The front shell of the ceiling mounted air purifier is connected to the base detachably by clasping the plural hooks on the top of the base, so the front shell can be detached from the base easily.
2. The air inlet filters inserted in the air inlet passages of the base is easily disassembled for daily maintenance.
3. The filter cartridge container is connected to the winnower air exit detachably by plural elastic hooks, so a filter cartridge can be popped out for change of a filter cartridge by gently pressing the filter cartridge container.
4. The present invention mounted on ceiling occupies less ground space than the traditional vertical air purifier and thus achieves efficacy of saving space.
5. The front shell is engaged with and positioned to the base by plural hooks, so the front shell can be released from the hooks easily in disassembling. Therefore, the design of the present invention is convenient for disassembly and daily maintenance.
6. The ceiling mounted air purifier disposed with a LED illumination element further provided illumination.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

To provide a thorough understanding of the present invention, an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.
As showed in FIGS. 1-4, a ceiling mounted air purifier of the present invention comprises: a winnower (1), a base (2), a back shell (3), two air inlet filters (4), a filter cartridge container (5), and a front shell (6). The winnower (1) has two winnower air entrances (11) on two sides thereof, a winnower air exit (12), and a windshield (13) disposed between the winnower air exit (12) and the base (2). The base (2) has a recessed groove (21) disposed below a middle thereof for accommodating the winnower (1), two air inlet passages (22) shaped with frame-shaped structures and disposed on two sides of the recessed groove (21) respectively, and an integrated air exit (23) disposed at a top thereof and corresponding to the winnower air exit (12) of the winnower (1). The integrated air exit (23) of the base (2) is tightly connected to the winnower air exit (12) of the winnower (1) by the windshield (13). The back shell (3) is disposed at a bottom of the base (2) to position the winnower (1) in the recessed groove (21) and seal bottoms of the two air inlet passages (22). The two air inlet filters (4) are respectively inserted into exits of the two air inlet passages (22) and corresponding to the two winnower air entrances (11). The filter cartridge container (5) is disposed on the winnower air exit (12) of the winnower (1), and the front shell (6) disposed at the top of the base (2) to release filtered air.
The front shell (6) is provided with a fixed frame (61) shaped with a hollow portion in a middle thereof, a light cover (62) engaged with a top of the fixed frame (61), and an air outlet net (63) correspondingly disposed on the hollow portion of the fixed frame (61). The base (2) is disposed with plural hooks (7) on the top thereof for connecting to the front shell (6) detachably by clasping the fixed frame (61). The fixed frame (61) is further provided with a LED illumination element (8) and an air quality indicating unit (9).
Preferentially, the filter cartridge container (5) is connected to the winnower air exit (12) of the winnower (1) detachably by plural elastic hooks, so a filter cartridge container (5) can be popped out for maintenance or change of a filter cartridge by gently pressing the filter cartridge container (5).
As shown in FIG. 5, the air purifier of the present invention is mounted on a ceiling (10) in a way that the air outlet net (63) of the front shell (6) is faced to an interior space of a room, and the back shell (3) is disposed toward an interior space of the ceiling (10). After the ceiling mounted air purifier of the present invention is turned on, the air flows into the air inlet passages (22). After large dust particles in the air is filtered by the two air inlet filters (4) inserted into the exits of the air inlet passages (22), the filtered air is inhaled into the two winnower air entrances (11) by fan blades disposed on two sides of the winnower (1) and then purified by the filter cartridge accommodated within the filter cartridge container (5). The purified air is then released to the interior space of a room by passing through the integrated air exit (23) of the base (2) and the air outlet net (63). Except for the air entrances and the air outlets, the junction of the air inlet passages (22), the windshield (13), the integrated air exit (23) of the base (2) are tightly sealed, so the present invention achieves efficacy of increasing air pressure as well as enhancing effects of air release and filtration.
In addition, the LED illumination element (8) and the air quality indicating unit (9) are provided along with the light cover (62) to provide illumination and indication of operational status, which improves convenience in use.
