Background technique
Traditional fan is to produce wind with the driven by motor blade rotation, and this type of fan is owing to needing the blade rotation, though blade is sheathed with outer cover institute; But still there is certain potential safety hazard; And cleaning is very inconvenient, and assembly is more, needs dismounting one by one to clean and to safeguard.For this reason, people have used a kind of novel no blade fan, and it need not blade, and air sucks via intake grill, and under the compression and promotion of motor, are seen off to exhaust outlet by the water conservancy diversion air channel, have solved the safety and the cleaning problems of fan.But the intake grill of existing no blade fan all designs on the outer wall of main body side, and the side air inlet mouth very easily sucks dust or tiny article, has both had certain potential safety hazard, makes its internal component be prone to stolen goods, is difficult for cleaning and maintenance.
Therefore,, a kind of pollutant that is difficult for adhering to is provided to the problems referred to above, easy to clean and safeguard, and the more excellent no blade fan of Security is particularly necessary.
Summary of the invention
For overcoming above-mentioned technological deficiency, the purpose of the utility model provides a kind of ash that is difficult for falling, easy to clean and maintenance, and the more excellent no blade fan of Security.
The utility model provides a kind of no blade fan with hidden intake grill; Comprise main body, be positioned at the base that vane and be positioned at bottom part body at main body top, said air-out is equipped with exhaust outlet, is provided with motor in the said base; Said main body comprises water conservancy diversion air channel and air intake device; Air intake device is provided with several intake grills, and said intake grill is distributed in the air intake device bottom, and intake grill, water conservancy diversion air channel and exhaust outlet are interconnected.
The utility model also further comprises following some additional technical feature:
Said air intake device comprises connecting end and air intake, and an end of air intake device is connected with the water conservancy diversion air channel through connecting end, and air intake offers fixed hole, and the other end of air intake device removably is assemblied on the base through fixed hole.
The diameter of said connecting end is greater than the diameter of air intake, so that after air got into from said intake grill, its circulation was more smooth and easy; The perforate section area of said intake grill is the 60%-500% of said exhaust outlet section area, preferably, is 300% of said exhaust outlet section area.
Said intake grill be surrounded on fixed hole around.
Said intake grill and base are oppositely arranged.
Said intake grill and base parallel.
Said air intake device is the ring-type groove, and the cross section of the said groove axis in edge is U type, V-type or trapezoidal, and its cross section is circle or polygonal.
Compared with prior art, the said no blade fan of the utility model adopts the design of recessive type intake grill, and intake grill is opened in bottom part body, and is relative with base; Both guaranteed good air intake effect, simultaneously, because of intake grill is offered down; Significantly reduced dust and got into fan inside, guaranteed the inner cleaning of fan by intake grill, and; Avoided tiny article, got into from intake grill, effectively improved the Security of fan like foreign matters such as iron wires.Adopt split-type structural, air intake device and water conservancy diversion air channel fit together removably each other, are easy to dismounting, maintenance and cleaning.This shows that the utility model adopts the no blade fan of recessive type intake grill, changed the position of offering of intake grill, the Security that has improved fan makes that the fan outside is cleaner, and easy to clean and maintenance.
