Abstract
The utility model relates to the fan base plate field, in particular to an improved base plate structure of fan, which comprises a base plate, an air duct and a fan. The air duct is hollow and is connected to a through hole at bottom of the base plate. The fan is fixed to the air duct through a frame, and the space between outer wall of the air duct and inner wall of the base plate is a tank. The air duct is connected to the center of the base plate, both forming one piece, upper part of the air duct is of curved surface structure and lower part is of pyramidal face structure. As the air duct and the base plate are formed into one piece, no transitional joint is provided between the air duct and the base plate. In addition, noise can be reduced through optimization of curve of inner wall of the air duct. After the fan is fixed to the air duct, shock resulting from working is passed to the base plate through the air duct, accordingly shock can be weakened and noise can be reduced easily by taking corresponding measures to the base plate; and service life of the air duct is improved for reduction of shock of the air duct.
Description
Technical field:
The utility model relates to the chassis technology field of blower fan, refers in particular to a kind of chassis structure improvement of blower fan.
Background technique:
At present, the air conducting tube on existing blower fan chassis all is installed on the chassis by fixing device, and blower fan is installed on air conducting tube then.The air conducting tube erasure effect of existing blower fan is all poor, because the curve of air conducting tube directly has influence on the efficient and the noise performance of blower fan, the vibrations that produce during blower fan work can be delivered on the air conducting tube, if the curve design of air conducting tube is unreasonable, the vibrations of air conducting tube can make whole blower fan send bigger noise, and the noise reduction of fan brings difficulty, and air conducting tube is in vibrating state for a long time simultaneously, can reduce working life greatly, for the later maintenance of blower fan makes troubles.
The model utility content:
The purpose of this utility model is exactly the chassis structure improvement that a kind of blower fan is provided at the deficiency of prior art existence, and it has overcome the deficiency that the vibrations of existing blower fan chassis are big, noise is big.
To achieve these goals, the technical solution adopted in the utility model is: it comprises chassis, air conducting tube, blower fan, air conducting tube is a hollow structure, communicate with the through hole that tray bottom is opened, blower fan is fixed on the air conducting tube by frame, and the space between air conducting tube outer wall and the chassis inwall is a tank, and air conducting tube is shaped in chassis central authorities, the air conducting tube upper inside wall is a curved-surface structure, and the bottom is a cone structure.
Form outlet column on the base plate of tank, outlet column is a hollow structure, and the ingress of outlet column is provided with water proof cover, and base plate has through hole at the outlet column place and communicates with outlet column.
After adopting said structure, because air conducting tube and chassis are integrated, do not exist the transition between air conducting tube and the chassis to connect, the curve negotiating optimization of air conducting tube inwall can reach the purpose that reduces noise; After blower fan was fixed on the air conducting tube, the vibrations meeting that produces during work was delivered on the whole chassis by air conducting tube, at this moment taked corresponding shock absorbing measure just can be easy to vibrations are weakened on the chassis, reduced noise; Because the vibrations of air conducting tube reduce, extend its working life; In addition, it is integrated structure that the utility model adopts air conducting tube and chassis, has optimized processing technology, has reduced cost of production.
Description of drawings:
Fig. 1 is a Facad structure schematic representation of the present utility model;
Fig. 2 is a bottom surface of the present utility model structural representation;
Fig. 3 is the sectional view of Fig. 1.
Embodiment:
See shown in Fig. 1,2,3, the utility model comprises chassis 1, air conducting tube 2, blower fan 3, air conducting tube 2 is a hollow structure, the through hole of opening with 1 bottom, chassis communicates, blower fan 3 is fixed on the air conducting tube 2 by frame 4, and the space between air conducting tube 2 outer walls and chassis 1 inwall is a tank 5, and air conducting tube 2 is shaped in chassis 1 central authorities, air conducting tube 2 upper inside wall are curved-surface structure, and the bottom is a cone structure.Because air conducting tube 2 and chassis 1 are integrated, do not exist the transition between air conducting tube 2 and the chassis 1 to connect, and the curve of air conducting tube 2 inwalls can reach the effect that reduces noise by optimizing.After blower fan 3 was fixed on the air conducting tube 2, the vibrations meeting that produces during work was delivered on the whole chassis 1 by air conducting tube 2, at this moment taked corresponding shock absorbing measure just can be easy to vibrations are weakened on chassis 1, reduced noise.
Form outlet column 6 on the base plate 51 of tank 5, outlet column 6 is a hollow structure, and the ingress of outlet column 6 is provided with water proof cover 61, and base plate 51 has through hole at outlet column 6 places and communicates with outlet column 6, be fixed with electric control box 7 on the air conducting tube 2, the circumscripted power line of electric control box 7 is guided to 1 outside, chassis by outlet column 6.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and are included in the utility model claim.
