Abstract
The utility model relates to an indoor and outdoor air exchanger, in particular to an exhaust fan, in which a power switch and a shutter are linked for opening and closing. The exhaust fan is composed of a shell, a motor and fan blades; the shutter is arranged on the wind outlet surface of the shell; the exhaust fan further comprises a link bar to push the on-and-off of the power switch; the power switch is connected in series with the operating circuit of the motor; and one end of the link bar is movably linked with the shutter. The indoor and outdoor air exchanger has the advantages that (1) exhaust is started when the link bar is pulled, at the same time the link bar pulls the shutter to open, thereby effectively improving the exhaustion capability; and (2) the exhaust is stopped, a reset spring pulls the link bar upwards, and the shutter is closed and difficult to open by wind under the action of the spring normally.
Description
Technical field
The utility model relates to a kind of indoor and outdoor air exchanger, specifically is the ventilating fan that the interlock of a kind of power switch and louver opens and closes.
Background technique
The use of ventilating fan is very extensive, every family almost, each hospital ward, hotel room etc., the live room of having a rest of suitable crowd all is equipped with the ventilating fan of indoor and outdoor air exchange usefulness, it is a kind of very common family expenses life product, announce that as country a model utility name is called a kind of mosquito-proof rope ventilating fan, the patent No. is 200420015552.1, its structure is the housing that comprises ventilating fan, motor, flabellum, the outlet air surface of housing is provided with louver window, the screen window of screen net structure is set, the above-mentioned deficiency that also exists: 1 on the wind face of housing, when air draft, mainly rely on high wind to blow louver window open, could discharge outdoor, but exhaust air rate is weakened, make its air draft deleterious; 2, the screen window of screen net structure is set on the wind face of housing, and long screen window will be clogged by dirt service time, lose the effect of ventilation.
The model utility content
The purpose of this utility model is to overcome above-mentioned shortcoming, provides ventilating fan to open simultaneously when starting or closing or a kind of ventilating fan of closed louver window and good exhaust effect.
The utility model is realized with the following methods: be made up of housing, motor, flabellum, the outlet air surface of housing is provided with louver window, it also has a linkage rod to promote the break-make of power switch, and power switch is serially connected with the working circuit of motor, and an end of linkage rod connects with louver window is movable.
Connect by pull bar between described linkage rod and the louver window.
Be serially connected with extension spring on the described pull bar.
Described louver window is provided with Returnning spring.
Described power switch is arranged at the side of linkage rod, and linkage rod is provided with a breach, and breach corresponds to the conducting plate of power switch.
Described linkage rod is provided with self-locking device.
Described linkage rod is provided with the corner block of a self-locking device in the box body on a box body, latch nook one end is buckled on the linkage rod, and the other end movable hook constitutes the self-locking device of linkage rod on the corner block of self-locking device.
Described linkage rod is serially connected with a stay cord with the movable the other end that connects of louver window.
The beneficial effects of the utility model are: 1, just start exhaust in the pulling linkage rod, the louver window of linkage rod pulling is simultaneously opened, and effectively improves the air draft ability; 2, stopping air draft, Returnning spring pulling linkage rod makes progress, and louver window cuts out, and is difficult for being opened by wind in spring action usually.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is Returnning spring and louver window linkage structure schematic representation.
Fig. 3 is the self-locking device structural representation.
Specific embodiment
Below in conjunction with accompanying drawing the utility model is made concrete further instruction.
As shown in Figure 1, 2, be made up of housing 1, motor, flabellum 3, the outlet air surface of housing 1 is provided with louver window 4, and it also has a linkage rod 5 to promote the break-make of power switch 6, power switch 6 is serially connected with the working circuit of motor, an end of linkage rod 5 and 4 movable connections of louver window.
Connect by pull bar 7 between described linkage rod 5 and the louver window 4, be serially connected with extension spring 701 on the pull bar 7.
Described louver window 4 is provided with Returnning spring 8, and Returnning spring 8 one ends are connected in louver window 4, and the other end is connected on the housing 1, and effect is that the window page or leaf of louver window 4 resets fast and spurs linkage rod 5 and makes progress fast.
Described power switch 6 is arranged at the side of linkage rod 5, and linkage rod 5 is provided with a breach 501, and breach 501 corresponds to the conducting plate 601 of power switch 6, implements the conducting machine operation simultaneously and carry out air draft when making louver window 4.
As shown in Figure 3: described linkage rod 5 is provided with self-locking device 9.
Described linkage rod 5 is provided with the corner block 901 of a self-locking device 9 in the box body 2 on a box body 2, latch nook 902 1 ends are buckled on the linkage rod 5, and the other end movable hook constitutes the self-locking device 9 of linkage rod 5 on the corner block 901 of self-locking device 9.
Described linkage rod 5 is serially connected with a stay cord with the louver window 4 movable the other ends that connect.
Working principle: pulling linkage rod 5 is downward, and linkage rod 5 drives louver window 4 and opens; Simultaneously, linkage rod 5 moves down a segment distance to moving down, and the conducting plate 601 of power switch 6 falls within the breach of interlock masthead, and conducting plate 601 links to each other, and power turn-on and motor rotate air draft.
