Description
Technical field
The utility model relates to blower fan, is specifically related to a kind of blower fan with shutter.
Background technology
Fan outlet is generally provided with shutter, and when fan starting, shutter is opened automatically, is beneficial to blower fan air draft, and when blower fan stops, shutter is closed automatically, prevents reverse flowing of air flows, rainwater-proof, anti-mouse etc. Existing fan shutter is to pass through connecting rod, louvre blade is page by page rotatably installed in the framework of blower fan, louvre blade and window frame Split type structure, in the time needing repairing at every turn or clean blower fan, all will take every one page louvre blade apart, dismounting difficulty, operation is loaded down with trivial details, when assembly fee, very inconvenient, sometimes in disassembly process, slightly do not note also can damaging louvre blade, so that will again change louvre blade. For this reason, be necessary to research and develop the simple blower fan structure of a kind of assembling, come easy to use.
Utility model content
Dismantle inconvenient technical problem in order to solve shutter, the utility model provides a kind of rational technical scheme as follows:
A kind of blower fan, comprise blower fan body and shutter, blower fan body by outer field case, be positioned at the motor at case center, the impeller that is connected with motor output shaft forms, shutter comprises framework and multiple louvre blade, louvre blade is rotatably installed in framework, framework is fixedly connected with case, and shutter shelters from the air outlet of blower fan body by framework with the entirety that coordinates of case.
Shutter comprises framework, rotating shaft, connecting rod and multiple louvre blade, and connecting rod is placed on the vertical frame inside of framework, and rotating shaft one end connecting rod connects; The other end is connected with louvre blade through the vertical frame of framework, and framework connects as one structure by cooperation and the louvre blade of rotating shaft and connecting rod.
Preferably, described rotating shaft is Z-shaped.
Preferably, described connecting rod below is provided with weight.
Preferably, described framework is fixedly attached to case by the screw of surrounding.
The beneficial effects of the utility model: while adopting blower fan of the present utility model, blind integrated is installed to the air outlet of blower fan body, convenient disassembly, do not need every one page louvre blade to remove, just can clean easily or keep in repair blower fan, save man-hour, framework connects as one structure by cooperation and the louvre blade of rotating shaft and connecting rod, be convenient to whole shutter to be installed to the air port of blower fan, simple and reasonable, in addition, Z-shaped rotating shaft coordinates with connecting rod, multiple louvre blades can be rotated simultaneously, there will not be indivedual louvre blade closures, the phenomenon that indivedual louvre blades open, ensure blower fan air draft smoothly.
Brief description of the drawings
Fig. 1 is that the utility model is arranged on the schematic diagram on blower fan;
Fig. 2 is exploded view of the present utility model;
Fig. 3 is the zoomed-in view of I in Fig. 2;
Fig. 4 is the exploded view of the utility model other direction;
Fig. 5 is the zoomed-in view of II in Fig. 4.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
As shown in Figure 1, a kind of blower fan, comprise blower fan body 1 and shutter 2, blower fan body 1 by outer field case, be positioned at the motor at case center, the impeller that is connected with motor output shaft forms, shutter 2 can be fixedly installed on the case of blower fan body 1 by the screw entirety of framework 4 surroundings, and shutter 2 shelters from the air outlet of blower fan body 1.
As shown in Fig. 2～3, shutter 2 comprises framework 4, rotating shaft 5, connecting rod 6 and multiple louvre blade 3, and connecting rod 6 is placed on the vertical frame inside of framework 4, and rotating shaft 5 one end connecting rods connect; The other end is connected with louvre blade 3 through the vertical frame of framework 4, framework 4 connects as one structure by cooperation and the louvre blade 3 of rotating shaft 5 and connecting rod 6, when the shutter of integrative-structure is installed to blower fan body 1, each louvre blade 3 of dismounting, has saved man-hour one by one.
In the time that one page louvre blade 3 rotates, louvre blade 3 drives connecting rod 6 to move up and down by rotating shaft 5, rotating shaft 5 is Z-shaped, can effectively transmit the rotational angle of every page of louvre blade 3, and drive easily connecting rod 6 to move up and down, connecting rod 6 drives other louvre blade 3 to rotate by rotating shaft 5 again, synchronously rotates thereby realize whole louvre blades 3, opens or closes shutter 2.
As shown in Figure 4 and Figure 5, connecting rod 6 belows are provided with weight 7, and weight 7 is placed in the vertical frame of framework 4. In the time that blower fan body 1 starts, wind, to louvre blade 3, makes louvre blade 3 open a little certain angle, and weight 7 continues drop-down connecting rod 6, louvre blade 3 is evened up, to open shutter completely.
When blower fan body 1 is worked, wheel rotation, wind is to shutter 2, and all louvre blade 3 is under wind action; turn an angle, open shutter 2, let in air, in the time that blower fan quits work; under the effect of louvre blade 3 gravity, shutter 2 is closed, and prevents that foreign matter from entering blower fan, plays a protective role.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model; can not assert that concrete enforcement of the present utility model is confined to these explanations; for the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
