Abstract
The utility model discloses an exhaust fan, comprising a casing, a motor arranged in the casing, a fan rotating by the motor, a casing net embedded on the casing and a shutter arranged at the back side of the casing, wherein, the joint of the casing and the shutter is provided with a movable hinge; the casing is provided with an elastic part; and one end of the elastic part is fastened on a boss of the end surface of the casing and the other end thereof is fastened on the movable hinge. When the shutter jumps up due to the wind pressure, the elastic part generates offset under the effect of wind force and carries out roof pressure to the movable hinge, therefore, the shutter is led to extend outward and flexibly under the assistant force of the elastic part and the extended angle is increased.
Description
Technical field
The utility model relates to a kind of ventilating fan.
Background technique
Ventilating fan is generally used for various public places or places such as kitchen, Rest Room, play the effect of ventilation, cooking-fume discharging, its structure of existing ventilating fan is generally the streamline air guide sleeve and is installed in covering interior motor and flabellum on the market, be positioned at outdoor covering side venetian blind is installed, the pivot that the free end side of this venetian blind outside base portion with pivot vertically rotates simultaneously as fulcrum.The ventilating fan of this structure has the following disadvantages: because venetian blind is positioned at outdoor, so maintenance is cleaned all very inconvenient when using, and when ventilating fan is used for the kitchen cooking-fume discharging, though venetian blind can be opened automatically when the exhaust flabellum rotated, but still be horizontally set with in the cooking-fume discharging passage, through the sticking long-pending a large amount of greasy dirts of meeting on the venetian blind after long-time the use, influence the unlatching of venetian blind so on the one hand, clean difficult on the other hand; Under the situation of having to dwindle because of the necessity that prevents inflows such as rainwater in the interval that covers in main body in covering, every fan venetian blind all is a smooth plate, therefore at venetian blind because when the blast that the fan rotation causes takeoffs, opens the air channel, its open angle is little, can't obtain big air displacement.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of easy to use, increase the venetian blind opening angle and reduce the ventilating fan that greasy dirt gathers.
Goal of the invention of the present utility model is achieved in that a kind of ventilating fan, the fan that comprises housing, is located at motor in the housing, rotates by motor, be flush-mounted in the cover net on the housing and be installed on the venetian blind of back side of shell, its middle shell and venetian blind joint are provided with hinges, it is characterized in that: described housing is provided with elastic component, this elastic component one end is buckled on the boss of housing end face, and the other end is buckled on the hinges.
Described boss is located on the housing inner side edge and with the housing one and is connected.
Have through hole on the described boss, elastic component is buckled in the through hole.
Described elastic component is V-shaped to be located on the housing.
Described elastic component is a spring.
The utility model improves the ventilating fan of prior art, is provided with elastic component and boss on housing, elastic component by with boss and the mutual snapping of hinges.When venetian blind takeoff owing to blast, the generation biasing under the effect of wind-force of elastic component while was carried out roof pressure to hinges, makes venetian blind under the power-assisted of elastic component, the outwards flexible and opening angle increase of stretching, extension.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model most preferred embodiment.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Shown in 1, ventilating fan of the present utility model comprises housing 1, motor, fan 2, cover net, venetian blind 3 and hinges 4 with reference to the accompanying drawings, and wherein motor is located in the housing 1, and fan 2 is located at housing 1 inside and is rotated by motor; The cover net is flush-mounted in housing 1 top, and motor and fan 2 intercept housing 1 outer atmosphere by the cover net; Venetian blind 3 is installed on housing 1 back side, and these venetian blind 3 one end faces are positioned at outdoor; Hinges 4 is located at housing 1 and venetian blind 3 joints, this hinges 4 stretches out a pair of rotary piece respectively to oblique below the state of part to interlock, coupling shaft is the string shape to be passed, the upper surface of a pair of rotary piece is fixed in the lower surface of every fan venetian blind 3, and venetian blind 3 flexibly connects by hinges 4 and housing 1.Housing 1 is provided with elastic component 5, the bending that is in the shape of the letter V of this elastic component 5, and the selection of elastic component 5 is spring the best; Housing 1 inner side edge is provided with boss 11, and this boss 11 is connected with housing 1 one, and boss 11 shape ringwise is to have through hole on the boss 11.Elastic component 5 one ends are buckled in the through hole on the boss 11, make the easy to connect and firm of elastic component 5 and housing 1; The other end of elastic component 5 is buckled on the hinges 4, specifically is that elastic component 5 is surrounded on the pivotal position of hinges 4 coupling shafts.Behind electrical power, the fan 2 that is installed on the motor rotation axis starts, venetian blind 3 takeoffs by blast, hinges 4 moves thereupon, promoting venetian blind 3 outwards stretches, elastic component 5 produces biasing hinges 4 is carried out roof pressure under the effect of wind-force and hinges 4, make venetian blind 3 under the power-assisted of elastic component 5, outwards stretches flexibly and the opening angle increase.
