Abstract
The invention discloses a base for a bladeless fan. The base comprises a shell, a pressure expander and a ventilating pipe. The pressure expander is arranged in the shell, the ventilating pipe is connected with the shell, and a sealing piece is arranged between the ventilating pipe and the pressure expander so that the ventilating pipe and the pressure expander can be in sealing connection. Therefore, due to the fact that the sealing piece is adopted, the ventilating pipe is in sealing connection with the pressure expander, airflow with pressure increased and speed reduced through the pressure expander enters the sealing piece, and then passes through the ventilating pipe, and it is guaranteed that the whole flowing path of the airflow is sealed, and therefore air leakage is avoided.

So, diffuser 14 is divided into upper element 140 and lower element 142, and upper element 140 is each with lower element 142
Self-forming gained, wind-guiding fin 14d is formed by connecting with lower wind-guiding fin 142c by upper wind-guiding fin 140c, due to wind-guiding fin
14d is divided into two parts, decreases the fracture that wind-guiding fin 14d causes because of contraction distortion.Further, bubbler 14 structure letter
Single, easy installation and removal, reduces assembling intensity and production cost.
In the present embodiment, sealing member 18 connects the upper end of ring-type connecting portion 162 and external wall of upper portion 140b, sealing member 18
Connect with air-guiding aisle 14c.
So, sealing member 18 connects the loop connecting portion 162 of breather 16 and the upper of external wall of upper portion 140b of diffuser 14
End, enters sealing member 18 from the upper end of diffuser 14 high pressure draught out and enters back into breather 16, due to employing sealing
Part 18 connects, and whole process air-tightness is preferable.
In the present embodiment, sealing member 18 is flexible pipe.
So, breather 16 and diffuser 14 are realized being tightly connected, thus improve shell 12 and the breather of pedestal 10
The air-tightness of 16 junction.
In the present embodiment, flexible pipe is rubber hose.
So, breather 16 and diffuser 14 are realized being tightly connected, thus improve shell 12 and the breather of pedestal 10
The air-tightness of 16 junction.
In the present embodiment, impeller 20 and the motor 22 for driving impeller 20,22, motor are contained in shell 12
Between diffuser 14 and impeller 20, diffuser 14 is located at the downstream that impeller 20 produces air-flow.
So, the air-flow that impeller 20 high-speed rotation produces is carried out slow down pressurization racemization by diffuser 14.
Specifically, it is formed with impeller housing 24 outside impeller 20, the lower element 142 of diffuser 14 is with impeller housing 24 even
Connect, outside motor 22, be formed with motor case 26, lower inner wall 142a of diffuser 14 extend downwardly connect with motor shell 26 with
Support motor shell 26.Shell 12 is substantially cylindrical, and the outer peripheral face of shell 12 offers air inlet 120, and air inlet 120 is by many
Individual circular hole composition.Motor 22 impeller 20 high-speed rotation to suck in shell 12 air outside shell 12 from air inlet 120
And forming the high velocity air moving upwards, high velocity air enters and carries out pressurization of slowing down in diffuser 14.
According to the bladeless fan of better embodiment of the present invention, including the pedestal 10 of head and any of the above-described embodiment,
Pedestal 10 is connected with head sends into head with the air-flow producing impeller 20.
In the present embodiment, head is connected with the breather 16 of pedestal 10, and head offers the spray for jet-stream wind
Mouth.
Specifically, diffuser 14 is located in the diffusion section of inlet air flow path of bladeless fan, the height that impeller 20 is formed
Pressure gas stream enters the air-guiding aisle 14c of diffuser 14, and wind-guiding fin 14d guiding air-flow enters breather 16 and leads to head, should
Air-flow can eject from the nozzle of head.Diffuser 14 is used for impeller 20 rotates the air inlet of the air-flow of formation towards breather 16
End 160 guiding, the upper end of the upper element 140 from diffuser 14 for the air-flow out and pass through sealing member 18 entrance breather 16 in from
And entering head, the whole sealing in the path of air current flow is so that ensure will not gas leakage.
