Description
Technical field
The utility model relates to a kind of three-dimensional wind regime fan, belongs to fan renovation technique field.
Background technique
At present, existing fan is structurally more single, the overwhelming majority adopts air-out above, air intake below, electric fan moulding structure can only meet this outlet and inlet mode, add the mode of shaking the head in left and right, to increase the coverage rate of wind-engaging, but existing fan there will be wind-engaging intermittently, in fan head swinging process, can consume a large amount of electric energy, the structure of the control section of shaking the head is especially easily damaged, and use after the time of one end when fan, above fan, be covered with dust, and be not easy to clean, so existing fan is still perfect not.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, safe and reliable, easy to operate, energy consumption is little, wind-engaging broad covered area, and the three-dimensional wind regime fan of the one of easily cleaning, to overcome the deficiencies in the prior art.
The utility model is constructed as follows: a kind of three-dimensional wind regime fan, comprise fan case, be respectively arranged with top intake grill and bottom air inlet mouth at the two ends of fan case, on fan case, be provided with exhaust outlet, rotating shaft is set in fan case, the bottom of rotating shaft is connected with motor, middle part in rotating shaft is provided with bearing, in rotating shaft and in the both sides of bearing, be respectively arranged with fan blade and lower fan blade, in the upper fan blade near top intake grill and bottom air inlet mouth and lower fan blade, be manufactured with the induced-draft plate tilting in the same direction.
The bottom of fan case is connected with fan base.
Be respectively arranged with upper air inlet screen cloth and lower air intake screen cloth at the top of fan case intake grill and bottom air inlet mouth.
Described exhaust outlet is arranged along the housing surrounding of fan case.
Owing to having adopted technique scheme, under the upper fan blade with induced-draft plate and lower fan blade effect, by air from top and bottom suction fan casing, and utilize the moulding of flabellum to guide to substantially horizontal air-flow, thereby realize three-dimensional circular air-out, the utility model compared to the prior art, the utility model not only has simple in structure, futuramic advantage, and have easy to operate, energy consumption is little, wind-engaging broad covered area, and easily clean, can realize the advantages such as three-dimensional circular air-out.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Enforcement of the present utility model: a kind of making method of three-dimensional wind regime fan, comprise fan case, on fan case, be manufactured with exhaust outlet, the top of fan case and bottom are manufactured with respectively top intake grill and bottom air inlet mouth, in fan case, be manufactured with rotating shaft, the bottom of rotating shaft is connected with motor, be manufactured with respectively fan blade and lower fan blade in the upper and lower of rotating shaft, be manufactured with the bearing that upper fan blade can be separated with lower fan blade at the middle part of rotating shaft, in the upper fan blade near top intake grill and bottom air inlet mouth and lower fan blade, be manufactured with the induced-draft plate tilting in the same direction, rotate by driven by motor rotating shaft, upper fan blade in rotating shaft and lower fan blade are along with rotating shaft is rotated, the induced-draft plate of rotation longitudinally enters in fan case air-flow, then by upper fan blade and the lower fan leaf of rotation, air-flow is accelerated from horizontal derivation fan machine housing, to reach from fan case, lower air intake, with the air-out of horizontal three-dimensional circular direction.
A kind of three-dimensional wind regime fan, comprise fan case 1, be respectively arranged with top intake grill 2 and bottom air inlet mouth 3 at the two ends of fan case 1, on fan case 1, be provided with exhaust outlet 4, rotating shaft 5 is set fan case 1 is interior, the bottom of rotating shaft 5 is connected with motor 6, be provided with bearing 7 at the middle part of rotating shaft 5, in rotating shaft 5 and in the both sides of bearing 7, be respectively arranged with fan blade 8 and lower fan blade 9, in the upper fan blade 8 near top intake grill 2 and bottom air inlet mouth 3 and lower fan blade 9, be manufactured with the induced-draft plate 10 tilting in the same direction.
The bottom of fan case 1 is connected with fan base 11.
Be respectively arranged with upper air inlet screen cloth 12 and lower air intake screen cloth 13 at the top of fan case 1 intake grill 2 and bottom air inlet mouth 3, can prevent that by the upper air inlet screen cloth 12 that arranges and lower air intake screen cloth 13 dust from entering in fan case 1 and being attached in upper fan blade 8 and lower fan blade 9, affect the rotating speed of fan.
