The beneficial effects of the utility model are: glue cover, glue cover is arranged by the air inlet in shell in the utility model
Upper have a flow-guiding channel, and combustion air passes through flow-guiding channel and enters installation cavity, glue cover can damping vibration attenuation, avoid combustion air with
The friction of glue cover generates noise, while can completely cut off or the propagation for the vibration that decays, to realize the purpose of vibration and noise reducing.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the exploded view of the utility model；
Fig. 3 is the cooperation schematic diagram of glue cover and wind wheel；
Fig. 4 is the structural schematic diagram of another embodiment of flow-guiding structure.
Specific embodiment
Referring to Fig.1~Fig. 4, the utility model are a kind of fan assemblies comprising shell 1, motor 21, wind wheel 22 and are led
Flow structure 3.It is connected with installation cavity 11, the air inlet 12 that is connected with installation cavity 11 and on shell 1 with installation cavity 11
Air outlet.Wind wheel 22 is located in installation cavity 11, and motor 21 is arranged on shell 1, and the shaft of motor 21 is connected with wind wheel 22.
Flow-guiding structure 3 includes the glue cover 31 being arranged at air inlet 12, has a flow-guiding channel 311 on glue cover 31.
At work, combustion air pass through flow-guiding channel 311 enter installation cavity 11, glue cover 31 can damping vibration attenuation, avoid
Combustion air and the friction of glue cover 31 generate noise, while glue cover 31 can completely cut off or decay the propagation of vibration, avoid causing water heater
The vibration of upper other component optimizes the usage experience of user to realize the purpose of vibration and noise reducing.In addition, setting glue cover 31 may be used also
It avoids other component from leading to failure because of vibration, extends the service life of water heater.
The inner sidewall of flow-guiding channel 311 is connected with the front end face of glue cover 31 by cambered surface, and inlet air flow path can be improved
Smoothness, reduce friction and vibration, while the sectional area of 311 front of flow-guiding channel can be increased, to suck more air.
There is an air-inlet cavity 221, the rear end of flow-guiding channel 311 extends in air-inlet cavity 221 on wind wheel 22.Combustion air can
Enter the air-inlet cavity 221 on wind wheel 22 directly through flow-guiding channel 311, the flow path of combustion air can be optimized, avoid water conservancy diversion
Combustion air in channel 311, which flows directly into, upsets air-flow in installation cavity 11.
Flow-guiding structure 3 further includes the pressure ring 32 being connected with shell 1, and the front of glue cover 31 has positioning convex platform 312, positioning
Boss 312 is between pressure ring 32 and shell 1, so as to position glue cover 31, avoids the mobile dislocation of glue cover 31.
