Background technique
At present, employed on the market fan is normally installed motor on fan housing, and machine shaft connects fan blade, and fan blade is directly exposed, and fan blade is covered by metal guard or plastic cement guard, to prevent personal injury accident.Mainly there is following shortcoming in the fan that uses at present: though first fan blade has been covered by guard, but for air intake and the air-out that influences fan within reason, guard can not be done too fine and closely wovenly, general adult's little finger of toe and children's finger still can put in the guard from mesh, especially children are thoughtless, under the situation of not adult's nurse security incident take place very; The second, the area of fan blade is usually bigger, and the fan blade of this external is easy to be infected with dust after long between in use, and the fan that uses in family especially, dust are being wrapped up in oil smoke and sticked in together on the fan blade extremely that difficulty cleans totally, have a strong impact on the outward appearance of fan; Three, existing fan just quickens air ventilation usually, generally is exactly to blow a cold wind over, and the fan that blows warm braw is specially also arranged in addition, and its price is also than higher certainly, yet, also very unpractical at present not only can blow a cold wind over, but also can blow the fan of warm braw.
The model utility content
The utility model is at the defective of prior art, and a kind of fan blade is built-in, rational in infrastructure, the Safety far of safe and reliable both cooling and heating but provide.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of both cooling and heating Safety far, comprise base, fuselage, fan housing, fan blade and fan electromotor, fuselage is installed on the base, and fan housing is installed on the fuselage, fan blade is connected with fan electromotor, fan electromotor connects power supply, and the switch control knob is installed on the fuselage, and it is characterized in that: described fan blade is built-in fan blade, fuselage is a cylinder mode, and built-in fan blade and fan electromotor are installed in fuselage interior; Offer intake grill one time on the fuselage wall of built-in fan blade below; Fan housing is the little horn-like structure in the big rear end of front end, its front end is a horn mouth, and the rear end is the secondary air intake mouth, and bell-mouthed area is greater than the area of secondary air intake mouth, the wall of fan housing is as the internal cavities formula structure that is made of inside and outside two layers of walls, and cavity forms the gasbag that is full of air; The contacted position of fan housing bottom outer wall and fuselage is provided with ventilated port; The positive position of fan housing offers exhaust outlet, and exhaust outlet is located at the gasbag front end and is communicated with gasbag; Perhaps the position near the secondary air intake mouth offers exhaust outlet on the fan housing inwall, and exhaust outlet is positioned at secondary air intake mouth the place ahead; Intake grill and fuselage cavity, ventilated port, gasbag, exhaust outlet, secondary air intake mouth and horn mouth are interconnected; The area of described secondary air intake mouth is greater than the area of an intake grill.
Further, the KMCH hotting mask is installed above built-in fan blade, the KMCH hotting mask is across above built-in fan blade, and the KMCH hotting mask is connected with DC electrical source, and KMCH is brilliant porcelain thick film electric heating substrate.
Further, connect into the rotating structure of fuselage by the non-directional permagnetic synchronous motor between fuselage and the base, the non-directional permagnetic synchronous motor connects power supply, can make the fuselage band fan housing like this and rotate together.
During use, connect power supply, built-in fan blade rotates under the drive of fan electromotor, thereby ambient air is sucked from an intake grill, passes the fuselage interior cavity, enters gasbag from ventilated port, blows out from exhaust outlet again; Air is when exhaust outlet blows out and blow outward, and the air-flow of formation is brought the air of secondary air intake mouth back into, and blows out from horn mouth, can increase air output greatly by the secondary air intake mouth, and the ventilation of secondary air intake mouth is approximately 4 times an of intake grill.If blow warm braw, as long as the KMCH hotting mask is connected power supply, air just has been heated into warm braw after by the KMCH hotting mask.
Model utility adopts the built-in hiding mode of fan blade, is about to fan blade and motor and is installed in fuselage interior, thereby make the utility model not have fan blade to expose outside, has so just eliminated potential safety hazard, has high safety coefficient; Install in the fan blade front in addition one can heated air the KMCH hotting mask, make the utility model can blow out warm braw, can both cooling and heating, be extremely practical product.
