Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model detailed description of the invention is described:
Fig. 1 and Fig. 2 shows detailed description of the invention of the present utility model, as shown in the figure, the utility model discloses a kind of efficient automobile seat cushion extractor fan of compact conformation, this extractor fan is mainly used in the ventilation mattress that automotive seat use, its structure is made up of the fan component 2 be arranged in shell 1 and control circuit board, described shell is provided with ventilation inlet and air outlet, this shell has the structure of squarish; Described fan component 2 comprises prevailing wind dividing plate 3 and fan body 4;
Described shell divide is air intake cavity and air-out cavity by prevailing wind dividing plate 3, prevailing wind dividing plate 3 is provided with the fan mounting holes matched with fan body 4, is provided with fan body 4 in described fan mounting holes; Realize being communicated with by the fan mounting holes on prevailing wind dividing plate between above-mentioned air intake cavity and air-out cavity.So when in use, all rate of air circulation are all have fan body to control, and the rotating speed therefore controlling fan body can realize the object precisely controlling charge air;
Extractor fan in the utility model is mainly used in the ventilation mattress adopting air suction mode work, therefore adopts this structure not only can produce stronger exhaust capacity, and achieves the object precisely controlling the charge air in ventilation mattress; Charge air then determines the cold and hot degree of user's impression completely.
As shown in the figure, described prevailing wind dividing plate 3 is inclined in shell, and described fan body 4 is arranged on prevailing wind dividing plate; Under considering not destroy the prerequisite of automotive seat outward appearance, the most rational installation site of the present utility model is the gap place between back of seat and ventilation mattress; But its sectional dimension cannot provided with fan, therefore have employed in utility model and be obliquely installed prevailing wind dividing plate, by this vibrational power flow, not only achieve the relatively large-sized fan body of installation to improve exhaust capacity, also make the flow direction of air more smooth and easy simultaneously.
Being arranged in the utility model of described prevailing wind dividing plate 3 also has another structure, and namely described its cross section of prevailing wind dividing plate is that zigzag is arranged in shell, and described fan body is arranged on prevailing wind dividing plate.Same this structure also can obtain very smooth air flowing.It should be noted that due to what adopt in the utility model it is the mode of bleeding, so fan body preferably uses turbofan; Described its cross section of prevailing wind dividing plate is that zigzag is arranged in shell, above-mentioned zigzag is close to rectangular shape, by adopting the prevailing wind dividing plate of this structure, shell divide can be become two relatively independent cavitys equally, in the fan mounting holes that fan is then disposed thereon.
In order to further improve the shape of air communication channel, reduce the resistance of air flowing.Described shell at least side is provided with the side wind-guiding dividing plate 7 of arc, if all arrange above-mentioned side wind-guiding dividing plate 7 in the both sides that shell is corresponding, then the cross section of two side wind-guiding dividing plates 7 then in two back to C word shape, fan body is then just in time positioned at the narrowest middle position, can ensure that fan body has higher exhausting effect like this; Described prevailing wind dividing plate 3 edge is fixed on side wind-guiding dividing plate 7, forms annex installation cavity between curved side wind-guiding dividing plate 7 and shell; The utility model is while the wind-guiding diaphragm structure of employing side, additionally provide above-mentioned annex installation cavity, can the electronic unit in above-mentioned extractor fan and circuit card etc. be arranged in above-mentioned annex installation cavity like this, by the employing of this structure, solve the object that annex is installed and improved air communication channel shape simultaneously.
Consider that wind inlet of fan needs to be connected with the seat cushion air draft pipe on seat cushion, therefore conveniently this connection, in described wind inlet of fan outer rim, the fin around ventilation inlet edge is set, have and then correspondingly with one end of seat cushion air draft pipe arrange groove or fin, whole realization utilizes this fin for the connection with seat cushion air draft pipe; And described air outlet is provided with grid.
By reference to the accompanying drawings the utility model preferred implementation is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from the utility model aim.
Do not depart from design of the present utility model and scope can make many other and change and remodeling.Should be appreciated that the utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
