Abstract
The utility model provides a household electric fan, an axial air inlet is arranged on a housing, a barrier is arranged on the air inet. The utility model is characterized in that a guide vane is arranged at the outer side of the barrier; a radial air inlet is formed between the guide vane and the housing. The inlet direction of the electric fan is changed from an axial direction to a radical direction in the utility model, thereby effectively preventing that the mosquito net is attracted to cover the air inlet when the electric fan is used on a bed, and avoiding the danger that the mosquito net is rolled into the electric fan.
Description
Technical field
The utility model relates to the domestic electric fan technical field, particularly can place bed to go up the family expenses axial flow electric fan that uses.
Background technique
At present, existing domestic electric fan, particularly the structure of axial flow electric fan includes the housing of fixed electrical machinery, and air inlet through hollow shaft mouth and the exhaust outlet offered on housing, and the place is provided with fence at intake grill.During use, electric fan sucks air from the air inlet through hollow shaft mouth, and blows out from exhaust outlet.Though the fence at intake grill place can prevent foreign matter and enter in the fan, but because fence does not change the axial flow of air direction at intake grill place, therefore when electric fan places bed to go up use, still very easily mosquito net is attracted to be covered on the fence of intake grill, serious hinder air flows, even mosquito net is involved in blade causes danger.
Summary of the invention
The purpose of this utility model provides a kind of domestic electric fan that prevents to inhale the volume mosquito net.
The utility model is achieved in that domestic electric fan includes the housing of fixed electrical machinery, offers the air inlet through hollow shaft mouth on the housing, and the place is provided with fence at intake grill, especially, is covered with guide plate in the fence outside, forms radially intake grill between guide plate and the housing.During use, air is the radially intake grill through forming between guide plate and the housing earlier, just enters the air inlet through hollow shaft mouth through fence then.Because guide plate by axially changing into radially, attracts the air intake direction of fan to be covered in the intake grill place with mosquito net in the time of can preventing effectively therefore that fan from using in bed, has reached the purpose that prevents to inhale the volume mosquito net.
The utility model has the advantages that simple in structure, the Security that has improved electric fan.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, domestic electric fan includes housing 1, offers the air inlet through hollow shaft mouth on the housing 1, is provided with fence 2 at the intake grill place, and other has a guide plate 3 to cover on the outside of fence 2, and guide plate 3 is connected with four drift angles of housing 1 by pillar 4.Guide plate 3 also can be connected with the fence 2 of housing 1 in addition.Separated by a distance between the periphery edge of guide plate 3 and the housing 1, form one and enclose radially intake grill 5.Part edge and the housing 1 that can certainly be guide plate 3 are from forming radially intake grill, and other edge and housing 1 are tightly connected.Guide plate 3 both can be that surface plate also can be the curved plate of different shape.Also can offer one or more through holes 6 on the guide plate 3,, make air stream be far smaller than the resistance of the through hole 6 of flowing through, just can guarantee still that electric fan can not inhale the volume mosquito net through the resistance of intake grill 5 radially as long as the aperture of through hole 6 is less.
