Background technique
(application number: 201010130001.X) disclose a kind of fan for generation of air stream, this kind fan comprises the nozzle that is installed on the base portion to the Chinese patent application that on September 8th, 2010, publication number was CN 101825105A, and described base portion comprises frame; Be contained in the impeller chimney in the described frame, described impeller chimney has suction port and air outlet; Be positioned at the impeller of impeller chimney; Pass the motor of the air-flow of impeller chimney with generation with drives impeller, described nozzle comprises receiving from the air outlet slit of impeller chimney inner passage and the mouth of air-flow, air-flow penetrates from fan by mouth, and wherein the flexible seal member is between described frame and described impeller chimney.Because the overall sealing performance of flexible seal member is not good, particularly this flexible seal member comprises guide portion with cable leading guide hole so that the cable that is connected with motor passes, so that the high pressure draught of exporting from the impeller chimney air outlet turns back to the suction port of impeller chimney by the space the cable leading guide hole, therefore reduced the efficient of fan, had much room for improvement or optimize.
Summary of the invention
The present invention aims to provide a kind of improved fan to overcome above-mentioned defective of the prior art.The objective of the invention is to provide-fan that kind of working efficiency is higher.
In order to achieve the above object, the technical solution used in the present invention is: a kind of fan, it is characterized in that, described fan comprises base portion and the nozzle that is arranged on the base portion, described base portion comprises frame, be contained in the described frame and have suction port, the impeller chimney of air outlet and cable leading guide hole, be positioned at the impeller of described impeller chimney, drive described impeller passes the air-flow of described impeller chimney with generation motor, with the cable that is connected described cable leading guide hole and is connected with described motor, described nozzle comprises receiving from described air outlet inner passage and the relief opening of air-flow, described nozzle defines opening, air from the fan outside is passed through described opening from the air-flow suction that described relief opening sent, wherein, in the space of described cable leading guide hole, be provided with sealer.
In order effectively to stop the suction port that turns back to impeller chimney from the high pressure draught of impeller chimney air outlet output along the gap between frame and the impeller chimney, be provided with sealer in the gap between frame and impeller chimney.Preferably, in the wound impeller cover described gap in a peripheral week, all be provided with sealer.
Sealer is that everybody is familiar with, and described sealer comprises silicone rubber.
Described base portion can adopt various shape, and described base portion can be to be essentially column.
In a preferred embodiment, described base portion comprises the diffuser that is positioned at described impeller downstream; In another preferred embodiment, described base portion comprises the diffuser that is positioned at described impeller downstream, and described cable is connected to described motor by described diffuser; In yet another preferred embodiment, described diffuser comprises a plurality of fins, and described cable is by one in described a plurality of fins.
Preferably, described nozzle comprises that annular inner housing part and annular outer cover body divide, and described inner housing part and frame part limit described inner passage and described relief opening together.
The present invention has following good effect: apparatus of the present invention are provided with sealer in the space of cable leading guide hole, and be provided with sealer in the gap between frame and impeller chimney, space effectively having prevented from the high pressure draught of impeller chimney air outlet output along the cable leading guide hole and turn back to the suction port of impeller chimney along the gap between frame and the impeller chimney, thus significantly improved the working efficiency of fan.
Description of drawings
Fig. 1 is the schematic diagram of fan of the present invention.
Fig. 2 is the generalized section that A-the A line intercepts along the fan shown in the figure l.
Embodiment
Figure l is the structural representation from the fan of the present invention of device forward observation, and Fig. 2 is the sectional view that A-the A line intercepts along the fan shown in the figure l.Can find out from Fig. 1 and Fig. 2, with reference to the system of the XYZ coordinate among each figure, this kind fan comprises base portion 1 and the nozzle 2 that is arranged on the base portion 1; Base portion 1 comprises frame 3, be contained in have suction port 4 in the frame, the motor 12 of the impeller chimney 10 of being connected with the cable leading guide hole in air outlet 5, the impeller 11 that is positioned at impeller chimney 10, drives impeller 11 pass impeller chimney 10 with generation air-flow and the cable 13 that is connected cable leading guide hole 9 and is connected with motor 12; Base portion 1 also comprises the diffuser 15 that is positioned at impeller 11 downstreams, diffuser 15 is for having the fixed tray of a plurality of fins, motor 12 is fixedly connected with this fixed tray, and impeller chimney 10 also is fixedly connected with this fixed tray, and cable 13 is connected to motor 12 by a fin of this fixed tray; Nozzle 2 comprises that annular inner housing part 17 and annular outer cover body divide 18, and inner housing part 17 and frame part 18 limit together and be used for from the air outlet 5 receiving inner passage 7 and the relief opening 8 of air-flows and defining opening 6.
In the present embodiment, in the space of cable leading guide hole 9, be provided with sealer; Also be provided with sealer in the gap 14 between frame 3 and impeller chimney 10; Employed sealer is silicone rubber.Space effectively stoping like this from the high pressure draught of impeller chimney air outlet output along the cable leading guide hole and turn back to the suction port of impeller chimney along the gap between frame and the impeller chimney can significantly improve the working efficiency of fan.
