Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.
The utility model discloses a kind of fan, comprise housing and be placed on the interior fan assembly of housing, as depicted in figs. 1 and 2, described fan assembly comprises flabellum and is used for fixing the fixed block of flabellum, described housing is provided with and encloses bone 11, described fan assembly is placed on and encloses in the bone 11, and encloses bone 11 corresponding housing exhaust outlet positions and be provided with the ventilated port that is mated.
The utility model encloses bone 11 owing to being provided with on housing, fan assembly is placed on and encloses in the bone 11, enclose bone 11 round the flabellum setting, enclose bone 11 corresponding housing exhaust outlet positions and be provided with ventilated port, and ventilated port and exhaust outlet be equipped with, thereby enclose in bone 11 just is enclosed in flabellum, the wind that flabellum produces when rotated just blows out by ventilated port and exhaust outlet along enclosing bone 11, like this with regard to wind just not can to around blow out, and then reduced waste, indirect increase air quantity.
In the present embodiment,, described ventilated port is first opening 111, as shown in Figure 1, first opening 111 cooperates the exhaust outlet settings, first opening, 111 convenient settings is set enclosing on the bone 11, thereby be convenient to produce, and the 111 cooperation exhaust outlet settings of first opening, thereby be convenient to air-out.
Housing described in the utility model comprises fore shell 2 and the back covers of detachably fixing with fore shell 21, and the described bone 11 that encloses is arranged on back cover 1 top.
In the present embodiment, fan also comprises the motor that is connected cooperation with fixed block, motor is connected with circuit board by lead, the described bone 11 that encloses is provided with second opening 113 that is used to place lead, second opening, 113 placement leads are set makes motor and circuit board carry out electric connection, second opening, 113 convenient settings, and be convenient to place lead.In the present embodiment, described second opening 113 can replace with through hole, is promptly enclosing the through hole that is provided with on the bone 11 with placing lead, and through hole can reach same effect.The wind that produces for fear of flabellum outwards blows out from second opening 113, described fore shell 2 is provided with the block piece 21 that is placed in described second opening 113, block piece 21 is being set on the face-piece 2 and second opening 113 cooperates spacing in second opening 113 and between the block piece 21 lead, thereby block piece 21 just seals second opening 113 avoids the wind of flabellum rotation generation to blow out from second opening 113, and then just guarantees that the wind of fan assembly blows out from opening 111 as much as possible.
