The intake stack embedding is in the air intake 2000 top of furred ceiling, and the notch outer wall of intake stack laminates mutually with the air intake 2000's of furred ceiling inner wall, further avoids particulate matters such as dust, oil smoke to get into the furred ceiling electrical apparatus through the gap between the air intake 2000 of intake stack and furred ceiling, is favorable to avoiding the dust to pile up on the furred ceiling electrical apparatus, prevents that the furred ceiling electrical apparatus from blockking up, improves the security performance of furred ceiling electrical apparatus.
In this embodiment, the air inlet structure 1000 includes an air inlet slot, which includes a side wall and a top surface; wherein, the top surface is provided with a through hole for the lifting structure 1100 to pass through; the side wall is in a grid shape and used for air inlet; the technical means that the notch outer wall of air inlet duct and the 2000 inner wall of the air intake of furred ceiling were laminated mutually is favorable to the smooth air inlet of furred ceiling electrical apparatus to guarantee furred ceiling electrical apparatus's normal work, also be favorable to further avoiding particulate matters such as dust, oil smoke to get into the furred ceiling electrical apparatus through the air inlet 2000 gaps between air inlet duct and the furred ceiling, thereby avoid the dust to pile up on the furred ceiling electrical apparatus, prevent that the furred ceiling electrical apparatus from blockking up, improve the security performance of furred ceiling electrical apparatus.
As shown in fig. 5, 6, 9 and 10, optionally, the air intake structure 1000 of the present embodiment includes a filter screen 1500, a cross section of the filter screen 1500 is annular, and an outer side wall of the filter screen 1500 is attached to an inner side wall of the air intake duct. Wherein the arrows in fig. 9 indicate the direction of air flow.
Because the cross section of the filter screen 1500 is annular, the outer side wall of the filter screen 1500 is attached to the inner side wall of the air inlet duct; that is, the filter screen 1500 covers the surface of the air inlet grill 1400; then, air from the air inlet 2000 can enter the ceiling electric appliance only through the filter screen 1500, which is beneficial to purifying the inlet air, thereby prolonging the service life of the ceiling electric appliance.
Optionally, the filter screen 1500 can be fixed in the air inlet tank in a detachable manner such as clamping, screwing and the like, which is beneficial to the regular replacement and maintenance of the filter screen 1500.
This embodiment is owing to adopted air inlet structure 1000 to include filter screen 1500, and filter screen 1500's cross-section is cyclic annular, and the lateral wall of filter screen 1500 and the inside means of laminating mutually of intake stack are favorable to purifying the air inlet to improve furred ceiling electrical apparatus's life.
This embodiment still provides a furred ceiling electrical apparatus, includes foretell air inlet structure 1000.
Because the furred ceiling electrical apparatus in this embodiment has adopted above-mentioned air inlet structure 1000, when furred ceiling electrical apparatus was out of work, can close air intake 2000 for conceal layer and interior space mutual isolation, cut off the flow channel who conceals layer and room air, be favorable to reducing particulate matters such as dust, oil smoke and get into through air inlet structure 1000 and conceal the layer, thereby avoid the dust to pile up on furred ceiling electrical apparatus, prevent that furred ceiling electrical apparatus from blockking up, improve furred ceiling electrical apparatus's security performance.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
