The specific embodiment

As for detailed construction of the present utility model, application principle, effect and effect, then please refer to the explanation that accompanying drawing does can be understood completely:

See also Fig. 1 to Fig. 6, shown in this figure, as can be seen, the utility model monomer-type ventilating fan includes: a fixed plate body 10, its front end face is provided with a plurality of inlet air hole slots to form ventilating opening 11, then is provided with a plurality of fixing holes 12 at periphery, with the ceiling secure bond; One fan base 20 is made as blast chamber in it, and device has blower fan 21 and prime mover (fan motor), its front end is a socket face 22, and a plurality of holes seat 122 is set, and can be corresponding fixing with a plurality of fixing holes 12 of said fixing plate body 10 peripheries, the rear end then is provided with air outlet 23; Wherein: can be provided with lateral insert 13 after the ventilating opening of fixed plate body 10 11, just suitable with a laterally inserted filter screen 30, enter the airborne impurity of blast chamber with the filtering desire by ventilating opening 11, pollute blower fan 21 to avoid this impurity to invade.

Again, wherein the front end face of fixed plate body 10 can be set as different shape according to actual needs, as square, round etc.; And the set a plurality of fixing holes 12 of periphery, be beneficial to retaining element 121 and see through this fixing hole 12, the front end face of fixed plate body 10 lockings at fan base 20, and can and then cover that fan base 20 is used for fixed ceiling on socket face 22 and exposed retaining element 222 reduces the visual lofty sense of its outward appearance; Expand ventilating opening 11 external forms of certain distance again by fixed plate body 10 mediads outward, also can be set as different shape according to actual needs, Fig. 1 to Fig. 2 for example, therefrom the outer flaring of mind-set is big with the concentric square grid of majority groove; Therefrom the outer flaring of mind-set is big by the concentric round grid groove of majority for Fig. 5; Or as Fig. 3, Fig. 4 and shown in Figure 6, opening that forms etc. is parallel to each other by a plurality of long strip type grid grooves, be provided with storage tank in the rear end face and ventilating opening 11 corresponding positions of fixed plate body 10 especially, it installs one deck filter screen 30 at least, these filter screen 30 areas will be a bit larger tham ventilating opening 11, make the ventilating opening 11 can be fully by sealing cover.

Again at the front end face of fan base 20, the shape that can cooperate aforementioned fixation plate body 10 according to actual needs, the socket face 22 that can be set as different shape is arranged in pairs or groups, as fixed plate body 10 is square or round, then the front end socket face 22 of fan base 20 must be set as square or round, its inner spatial accommodation is provided with blower fan 21, rear end face space at blower fan 21 then is provided with air outlet 23, the periphery of aforementioned socket face 22 is provided with a plurality of fixing holes 221, peripheral trailing edge is anchored on the entity, with retaining element 222 lockings, be fixed on the physical objects again and make fan base 20 pacify.

The filter screen 30 that the rear end face of fixed plate body 10 and ventilating opening 11 corresponding places cover also can cooperate the shape of aforementioned ventilating opening 11 according to actual needs, and the filter screen 30 that can be set as different shape is arranged in pairs or groups; The setting of filter screen 30 also has several means to arrange in pairs or groups, and for example filter screen 30 is a square, can be provided with slot 13 in the rear end face of fixed plate body 10, and inserts filter screen 30 from inserting mouth 14 in the bank mode of inserting; Can be provided with square concave surface 131 to cooperate the external form of filter screen 30 with ventilating opening 11 corresponding positions in the rear end face of fixed plate body 10, again filter screen 30 is settled, then fixed plate body 10 is linked on the socket face 22 of fan base 20, filter screen 30 is folded in wherein, sees through fixing hole 12 with retaining element 121 again and make on the hole seat 122 that is locked in fan base 20; In addition if filter screen 30 is round, generally be that rear end face in fixed plate body 10 is provided with round concave surface 131 to cooperate the external form of filter screen with ventilating opening 11 external form corresponding positions, again filter screen 30 is inserted and lay, then fixed plate body 10 is linked on the fan base 20, filter screen 30 is folded in wherein is locked on the fan base 20 hole seats 122 with retaining element 121 again.

The embodiment of said exhaust fan, earlier socket face 22 trailing edges of fan base 20 are fitted in the exhaust outlet peripheral region of real object (as ceiling), see through fixing hole 221 on the socket face 22 with retaining element 221 again, fan base 20 is locked on physical objects, then filter screen 30 is put into fixed plate body 10, again fixed plate body 10 is locked on the front end face of fan base 20, so and finish the installment work of ventilating fan, after using a period of time, as long as substitute filter screen 30, as be insertion type, be about to old filter screen 30 and pull out from inserting mouth 14, change new filter screen 30, as being the storing formula, then earlier fixed plate body 10 is pulled down on fan base 20, is taken out old filter screen 30 and change newly again, and then fixed plate body 10 locked on fan base 20, get final product.

Therefore, the utility model monomer-type ventilating fan, really can provide a kind of effectively filtering to take out and draw the assorted dirt of airborne pollution, with entering of the pollution that prevents fan base 20 parts and insect, can perform the maintenance cleaning as long as regularly change clothes filter screen, its convenience improves relatively, also can relatively alleviate the difficulty of maintenance washes ventilating fan.
