Abstract
The utility model discloses a novel ventilation fan, which comprises a housing, a dynamo arranged in the housing and flabellums arranged on the dynamo shaft. A filtering net is arranged in the ventilating fan, a filtering net installing frame is arranged on the front panel of the housing of the ventilating fan, and the filtering net is arranged in the installing frame; The filtering net is arranged in the installing frame by screws or by means of clamping; The filtering net is positioned at the backside of the air inlet on the front panel of the housing and arranged at the backside of the air inlet on the front panel of the housing by screws or by means of clamping. As the utility model adds an airstrainer at the air inlet of the ventilating fan, the air can be filtered when passing through the filtering net, and the granules in the air can be completely filtered, making the air going indoors become pure and fresh or the interior of the ventilating fan keep clean.
Description
Technical field
The utility model relates to a kind of ventilation fan, is a kind of improvement technology of existing ventilation fan specifically.
Background technology
At present, ventilation fan is mainly used to promote indoor-outdoor air to flow, keep the fresh family expenses air regenerating device of room air, the more serious city of the more air pollution of industrial and mining enterprises particularly when the air in the external world is relatively poor, people often close window in case extraneous air enters into indoor, but indoor air obviously can increase in the back concentration of carbon dioxide that do not circulate for a long time, and people have to adopt ventilation fan that indoor air is exchanged mutually with outdoor air again.Existing ventilation fan is not installed air filter mostly, just simply indoor air is discharged within doors or outdoor air is sucked within doors, is difficult to satisfy people's instructions for use, and for this reason, people wish that ventilation fan has airfiltering function.
Summary of the invention
The purpose of this utility model provides a kind of ventilation fan that can filter air.
The utility model is achieved through the following technical solutions.
A kind of air scavenger fan comprises shell, motor in the enclosure is installed and is installed in flabellum on the machine shaft, it is characterized in that: be provided with screen pack in the described ventilation fan.
Described ventilation fan shell front panel is provided with the screen pack installing frame, and screen pack is installed in the installing frame.
Described screen pack is installed in the installing frame by screw or snap fit.
Described screen pack is positioned at the rear side of shell front panel air inlet.
Described screen pack is installed in the rear side of shell front panel air inlet by screw or snap fit.
Described screen pack activity is plugged in the slot of shell front panel air inlet rear side.
The utility model compared with prior art has the following advantages.
Because the utility model installs the overanxious net of an air additional at the air inlet place of ventilation fan, air can filter air during by screen pack, airborne particle can be filtered out fully, make the air in the inlet chamber become pure and fresh or the inside of ventilation fan is kept clean.Screen pack is installed in the front panel place of ventilation fan shell by the mode of screw or clamping or movable grafting, thereby can be convenient for changing and the cleaning and filtering net.
Description of drawings
Fig. 1 is the front view of the utility model ventilation fan;
Fig. 2 is the cutaway view of the utility model ventilation fan.
The specific embodiment
Below in conjunction with accompanying drawing the utility model ventilation fan is described in further detail.
As Fig. 1 and shown in Figure 2, ventilation fan mainly is made up of shell 1, motor and flabellum, flabellum is installed in the rotating shaft of motor, motor is fixedly mounted on the support in the shell 1, have a square screen pack installing frame on the shell front panel, screen pack 2 is positioned at installing frame, is symmetrically distributed with a pair of bayonet socket on the left and right sides side of installing frame, be provided with screens with the corresponding position of bayonet socket on screen pack 2, screen pack 2 is connected on the bayonet socket of installing frame by screens.Screen pack 2 is made up of plastic frame and silk screen, and it is together injection molded with plastic frame silk screen to be put into injection machine when injection moulding, for strengthening the intensity of screen pack, vertically is distributed with many reinforcements in plastic frame, and screens is arranged on the both sides of plastic frame.Screen pack 2 adopts snap fit fixedly to have the advantage of easy accessibility, and the dust on screen pack 2 can disassemble screen pack 2 more for a long time easily, can install easily again after having cleaned.Screen pack 2 can also adopt screw to install except adopting the snap fit installation, promptly on installing frame and screen pack 2 plastic frames screw hole is set.Screen pack 2 in the utility model ventilation fan also can be positioned at the rear side of shell front panel air inlet, dual-side at shell front panel air inlet rear side is provided with the slot that inserts for screen pack 2, to get final product in the screen pack 2 insertion slots during installation, cleaning is then extracted screen pack 2 as need, dismounting is very convenient, certainly, screen pack 2 also can be fixed on the rear side of shell front panel air inlet by screw, and these two kinds of mounting means all can reach application target.
