Abstract
The utility model relates to a forced fan, which is composed of a cross flow fan and a wind absorbing exhaustion fan. The utility model has an ultra-large wind amount. The utility model comprises a fan blade of the cross flow fan, blade fixing bodies of two sides of the fan blade of the cross flow fan, a fan blade of the wind absorbing exhaustion fan, blade fixing bodies which are connected with the wind absorbing exhaustion fan in a concentric mode, etc. The utility model is characterized in that the utility model utilizes the superposition theory of a wind source and the complementation effect of the secondary wind absorbing exhaustion of the cross flow fan and the wind absorbing exhaustion fan, uses a directional superposed wind source formed by a positive direction wind source and a peripheral wind source under the condition that space is limited, and a given rotary speed is restricted to reach the purpose of the large wind amount, reduce a noise ratio and extend the service life of a motor. The utility model is the ideal matching product of air conditioners, warm wind fans, fume exhaust fans, air cushion boats, etc.
Description
The utility model relates to a kind of high-power fan of being made up of axial-flow fan and suction wind fan with super large air quantity.
At present in the prior art, axial-flow fan and suction wind fan are two product structures that use separately, under relative product structure usage space and given motor speed restriction condition, improve air quantity of fan, has only the given motor speed of increasing, motor speed and dry sound are the proportional relation curves, improve rotating speed and have promptly improved dry sound accordingly, have reduced motor working life simultaneously.
The purpose of this utility model is to utilize the complementarity of axial-flow fan and suction fan fan, a kind of super large air quantity that has is provided, promptly do not increase given motor speed and dry signal to noise ratio, can under relative product structure usage space restriction condition, reach a large amount of wind purpose high-power fans again.
This high-power fan includes the axial-flow fan flabellum, the solid leaf body in axial-flow fan flabellum both sides, suction wind electric fan, the suction electric fan connects solid leaf body with one heart, fan anticreep clamping bolt protects and emits, its structure characteristic is that the inboard two ends of axial-flow fan increase suction wind fan is arranged, the annexation of above-mentioned device is: the axial-flow fan flabellum is connected with the solid leaf body in axial-flow fan flabellum both sides, the solid leaf body in axial-flow fan flabellum both sides is connected with suction wind electric fan outer end, the inner end of suction wind electric fan is consolidated the connection of leaf body with concentric connection of suction wind electric fan, and fan anticreep clamping bolt protects reverse being spirally connected of rotation of emitting and passing the motor or the transmission rotatable parts at high-power fan center.
This high-power fan is compared under the restriction condition that limits usage space with suction wind fan with independent axial-flow fan, because high-power fan structurally has the complementarity of secondary suction wind to use, making forward wind regime and peripheral wind regime produce stack uses, form the powerful air quantity of suction wind, this structure and have dry sound low characteristics, be the desirable auxiliary products of the supporting wind-force of air conditioner, warm-air drier, range hood and hovercraft etc., the use prospect is boundless.
High-power fan also can be as required different with purposes, make folk prescription to suction wind high-power fan, two-way suction wind high-power fan or two-way single suction air draft high-power fan and reverse double suction air draft high-power fan and subtend suction wind high-power fan.Accompanying drawing shows the embodiment of high-power fan, and wherein Fig. 1 is the front view of high-power fan.Fig. 2 is the A-A sectional view of Fig. 1.Fig. 3 is the B-B sectional view of Fig. 2.Fig. 5 is the C-C sectional view of Fig. 2.Fig. 4, Fig. 6 are the two-way suction sectional views of Fig. 1.In Fig. 5,6 is motor rotation axis.
In the present embodiment, high-power fan includes axial-flow fan flabellum 5, the two ends of axial-flow fan flabellum 5 are connected with the solid leaf body 1 in axial-flow fan flabellum both sides, the solid leaf body 1 in axial-flow fan flabellum both sides is connected with the outer end of suction wind electric fan 2, the inner end of suction wind electric fan 2 is consolidated 3 connections of leaf body with concentric connection of suction wind electric fan, suction wind electric fan connects solid leaf body 3 and motor or 6 cross-under of transmission rotatable parts with one heart, and motor or transmission rotatable parts 6 protect with fan anticreep clamping bolt and emit 4 oppositely to be spirally connected.
In the present embodiment, this product can be made the structural type of one-way type, two-way type, subtend type and flyback type.
