Description
Technical field
The utility model relates to a kind of blower fan, especially a kind of seat cushion blower fan.
Background technique
Present seat cushion is take materials such as leather substance, linen-cottons as main, but in summer etc. indoor or vehicle interior temperature very high in, the sweat that sitting goes out on cushion accumulates between health and the seat cushion, be difficult to distribute, especially the small of the back and buttocks, this people of some Drivers embody with it particularly evident.If sweat can not distribute for a long time, then easy breed bacteria is given birth to bedsore or long prickly heat etc., and is very unfavorable to health.
Given this, the seat cushion of energy ventilation and heat arises at the historic moment.General in seat cushion back and shank interlayer each fix one or two ventilating boards, be each ventilating board air blast by blower fan.This seat cushion all is to be back and shank air blast from external environment such as Che Nei or indoor absorbing air, but back and shank all are the positions of very easily suffering from cold, and the air in the environment directly blows back and shank are caught a cold.
In view of this, special the utility model that proposes.
The model utility content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of seat cushion blower fan that back and shank are caught a cold of being difficult for is provided.
For solving the problems of the technologies described above, the utility model adopts the basic conception of technological scheme to be:
A kind of seat cushion blower fan comprises blower fan base plate, flabellum, flabellum cover plate and blower fan cover plate; Described blower fan cover plate and blower fan base plate fasten and form flow blower casing; Described flabellum cover plate and blower fan base plate form the flabellum receiving cavity in described flow blower casing, and flabellum is installed in the described flabellum receiving cavity; Described blower fan cover plate and blower fan base plate form the air cavity with the ambient air conducting, the blower fan base plate be provided with air intake pipe orifice and with the air outlet tube mouth of flabellum receiving cavity conducting, be provided with intake grill at the upper surface of described blower fan cover plate and the upper surface of flabellum cover plate, air intake pipe orifice and the air outlet tube mouth of described blower fan base plate oppositely arrange.
Preferably, described air intake pipe orifice and air outlet tube mouth are arranged on the side of blower fan base plate.
Preferably, described flabellum receiving cavity is vortex shape, and described impeller is arranged on the center of described vortex shape flabellum receiving cavity.
Preferably, the air outlet tube mouth on the described blower fan base plate is positioned on the tangent direction of described impeller.
Preferably, the air-admitting surface on the described blower fan cover plate is less than the air intake pipe orifice area on the described blower fan base plate.
Preferably, described blower fan base plate, flabellum cover plate and blower fan cover plate are the engineering plastics material.
Preferably, described flow blower casing is thick is 16-18mm.
After adopting technique scheme, the utility model compared with prior art has following beneficial effect:
The utility model can absorb in back hot gas and the mixing chamber or in the car air be the shank air-supply, can reduce back and leg temperature, prevented that again shank from catching a cold.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Description of drawings
Fig. 1 is erection drawing of the present utility model;
Fig. 2 is explosive view of the present utility model.
Embodiment
As depicted in figs. 1 and 2, the utility model is a kind of seat cushion blower fan, comprises blower fan base plate 1, flabellum 2, flabellum cover plate 3 and blower fan cover plate 4; Described blower fan cover plate 4 and blower fan base plate 1 fasten and form flow blower casing; Described flabellum cover plate 3 forms the flabellum receiving cavity with blower fan base plate 1 in described flow blower casing, and an installation shaft 5 is arranged in the flabellum receiving cavity on blower fan base plate 1, and flabellum 2 is installed on this installation shaft 5; Described blower fan cover plate 4 and the air cavity of blower fan base plate 1 formation with the ambient air conducting, side on the blower fan base plate 1 be provided with air intake pipe orifice 6 and with the air outlet tube mouth 7 of flabellum receiving cavity conducting, upper surface at described blower fan cover plate 4 is provided with intake grill 8, the upper surface of flabellum cover plate 3 is provided with intake grill 9, and air intake pipe orifice 6 and the air outlet tube mouth 7 of described blower fan base plate 1 oppositely arrange.
Certainly, air intake pipe orifice 6 on the blower fan base plate 1 and air outlet tube mouth 7 are as long as satisfy oppositely, make one of them towards the back, but another is towards shank also air intake and air-out, but airflow direction and blower fan base plate 1 thickness during based on flabellum 2 rotation, it is best that air intake pipe orifice 6 and air outlet tube mouth 7 are located at the side.
During installation, towards the seat cushion back, air outlet tube mouth 7 is offered a plurality of intake openings towards shank on the seat cushion surface at this assembling place with the air intake pipe orifice 6 on the blower fan base plate 1 of this blower fan, so that air enters in indoor or the car.Intake grills indoor or the interior air process of car blower fan cover plate 4 upper surfaces enter air cavity during work, air intake pipe orifice 6 on the blower fan base plate 1 advances the hot blast at back, the air that enters enters the flabellum receiving cavity through the intake grill of flabellum cover plate 3 upper surfaces, and mixed warm wind is to shank.So both reduced back and leg temperature, prevented again that shank from catching a cold.
Preferably, described flabellum receiving cavity is the vortex shape of airflow direction when meeting flabellum 2 rotation, and described flabellum 2 is arranged on the center of described vortex shape flabellum receiving cavity.Such as Fig. 2, at blower fan base plate 1 a vortex shape groove 10 is set, flabellum cover plate 3 also is designed to same vortex shape, flabellum cover plate 3 covers on the vortex shape groove of blower fan base plate 1, thereby and the inserted sheet by flabellum cover plate 3 edges 11 inject to block in the groove of blower fan base plates 1 and form vortex shape flabellum receiving cavity.
Preferably, the air outlet tube mouth 7 on the described blower fan base plate 1 is positioned on the tangent direction of described flabellum 2.Airflow direction when meeting flabellum 2 rotation is convenient to air-out.
