The utility model has the advantages of simple structure, low in cost, and the practicality is strong, through the electric heat net, it is indoor to prevent that air that outdoor temperature is low excessively from directly getting into, makes the temperature indoor step -down, leads to user of service sick, the effectual potential safety hazard of having eliminated existence in the use, close the exhaust fan during operation through closing the key, the exhaust fan can automatic postpone to cut out by oneself after five minutes again, prevents that the exhaust fan from cutting out suddenly, and mechanical wear is great, has reduced the life cycle of exhaust fan.
Description
Technical field
This utility model relates to a kind of exhaust fan, particularly to a kind of exhaust fan with delay feature.
Background technology
Exhaust fan, is driven fan blade to rotate by motor and drives air-flow, make the spacelike controlled atmosphere electricity-saving appliance that indoor-outdoor air exchanges.Also known as ventilating fan.The purpose of air draft seeks to remove indoor air pollution, regulates temperature, humidity and sensory effect.Exhaust fan is widely used in family and public place.
But existing exhaust fan function singleness, air can only be displaced, when using in the winter time, can cause in the cold air inlet chamber of outdoor, cause indoor temperature too low, cause that user exists sick hidden danger, be not convenient to use.
Utility model content
The technical problems to be solved in the utility model is to overcome existing defect, it is provided that a kind of exhaust fan with delay feature, it is possible to prevents indoor temperature too low, makes user sick, effectively eliminated potential safety hazard.
In order to solve above-mentioned technical problem, this utility model provides following technical scheme:
A kind of exhaust fan with delay feature of this utility model, including housing and motor and arrange air outlet on the housing, the back side of described housing is fixing connects described motor, described motor is fixing connects rotating shaft, described rotating shaft stretches in described housing and fixes with threaded post and is connected, threaded with rotating basis in the end of described threaded post, it is fixed with blade in described rotating basis, it is fixed with electric network near described air outlet place in described housing, the top of described air outlet is fixed with opens key, the described side opening key is fixed with close key, the bottom of described air outlet is fixed with wind speed adjusting key, the side of described wind speed adjusting key is fixed with electric network temperature adjusting key, the side of described electric network temperature adjusting key is fixed with timing key.
As a kind of optimal technical scheme of the present utility model, the quantity of described blade is four.
As a kind of optimal technical scheme of the present utility model, the junction of described threaded post and described rotating basis is fixed with nut.
As a kind of optimal technical scheme of the present utility model, the side of described close key is fixed with vent.
As a kind of optimal technical scheme of the present utility model, in described air outlet, it is installed with protection network.
As a kind of optimal technical scheme of the present utility model, the side of described timing key is fixed with emergency stop switch.
This utility model reaches to provide the benefit that: simple in construction of the present utility model, cheap, and practical, by being provided with electric network, when exhaust fan works, when indoor air is discharged, the air being possible to prevent outdoor temperature too low is directly entered indoor, makes indoor air temperature step-down, causes that user of service is sick, effectively eliminate the potential safety hazard existed in use procedure, it is simple to use；By being provided with close key, in use, when stopping exhaust fan work by close key, exhaust fan can be closed after five minutes by automatically delaying more voluntarily, it is therefore prevented that exhaust fan is closed suddenly, causes that mechanical wear is relatively big, reduces the life cycle of exhaust fan.
Accompanying drawing explanation
Accompanying drawing is used for providing being further appreciated by of the present utility model, and constitutes a part for description, is used for explaining this utility model, is not intended that restriction of the present utility model together with embodiment of the present utility model.In the accompanying drawings:
