Abstract
The utility model relates to a ceiling pipeline scavenger fan, including back casing, main control circuit board and front panel, wherein main control circuit board installs in the back casing, and the front panel is installed in the air intake department of back casing, its characterized in that the back device of front panel has the backlight, and the backlight passes through the wire to be connected with main control circuit board electricity, and the regional device that the front panel corresponds the backlight has light-permeable member or is the light-permeable region. The utility model discloses owing to adopt the structure that there is the backlight at the back device of front panel, not only can realize the effect of decorative lighting, because the backlight uses direct current low-voltage electricity moreover, compare with the scavenger fan that prior art has the illumination function, its safe and reliable more, power is low, and the efficiency is high, and is longe-lived，The light is uniform and does not flicker, and the size, the dimension and the shape of the backlight source can be cut at will, so that the decoration of the front panel of the ventilating fan is greatly improved.
Description
Technical field
The utility model is a kind of smallpox pipeline ventilation fan, belongs to the improvement technology of smallpox pipeline ventilation fan patent.
Background technique
The existing smallpox pipeline ventilation fan that has illumination function generally will throw light on and do simultaneously to decorate usefulness, and there is following defective in this technology: the one, need to use forceful electric power, and Safety performance is poor; The 2nd, employed lamp tube service life is shorter; The 3rd, the shape in the shinny zone of panel and size are limited by fluorescent tube can, have reduced the ornamental of product; The 4th, power ratio is higher, and heating value is big, and light is inhomogeneous, and is dazzling etc.
Summary of the invention
The purpose of the utility model be to consider the problems referred to above and provide a kind of safe and reliable, power is low, the life-span is long, brightness can be adjusted on demand, light is even, the shinny region shape of panel and big or small unrestricted smallpox pipeline ventilation fan.
For realizing the foregoing invention purpose; The technological scheme of the utility model is: a kind of smallpox pipeline ventilation fan, comprise rear case, main control board and front panel, and wherein main control board is installed in the rear case; Front panel is installed in the intake grill place of rear case; The back side device that it is characterized in that said front panel has Backlight, and Backlight is electrically connected with main control board through lead, and the regional device of the corresponding Backlight of front panel has transmission element or is transmission region.
The rear side device of said Backlight has cover plate, and cover board arrangement is the back side of plate in front.
Said cover plate and front panel one are made.
Said main control board is installed in the circuit board box, and circuit board box is packed in the rear case.
Said Backlight is T4T5, LED, CCFL or EEFL light source.
The utility model is owing to be employed in the structure that the back side device of front panel has Backlight; Not only can realize the effect of decorative lighting, and because Backlight uses is the dc low-voltage electricity, the ventilation fan that has illumination function with existing technology is compared; Its safety and reliability; Power is low, and efficiency is high, and the life-span is long
,Light evenly, do not glimmer, Backlight size, size and shape can cut arbitrarily simultaneously, the ventilation fan front panel that has increased substantially ornamental.
