Abstract
The utility model discloses an entry clock device of fan, including the air intake end that is located the fan air intake and the air intake tail end that is located the impeller air intake, the air intake end is with streamlined convergent to air intake tail end, and the air intake tail end is enlargied gradually to impeller main part direction to be connected with the impeller main part, make the air intake link to become one with the impeller main part. The inlet clock device of the fan enables gas entering the inlet clock to be smoother, so that the efficiency of the fan is improved, and noise is reduced.
Description
Technical field
The utility model relates to a kind of inlet clock device of blower fan.
Background technique
Use blower fan that the air in one space is extracted out, and the technology that this air is directed at outside this space is a technology of generally using.This kind technology is widely used in the place of need decontaminate thing and harmful smog.
Though this kind technology is commonly used, when blower fan uses,, be unfavorable for the gas smoothness because fans entrance to the inlet clock between the impeller bodies is cone table shape (as shown in Figure 1), therefore caused the attenuating of fan efficiency, the increase of noise.
Summary of the invention
The purpose of this utility model is: a kind of inlet clock device of blower fan is provided, and this device can make the gas smoothness, thereby improves fan efficiency, reduces noise.
The technical solution of the utility model is: a kind of inlet clock device of blower fan, comprise intake grill beginning that is positioned at air inlet and the intake grill tail end that is positioned at the impeller intake grill, and the described intake grill beginning is with the streamlined intake grill tail end that is tapered to.
The further technological scheme of the utility model is: a kind of inlet clock device of blower fan, comprise intake grill beginning that is positioned at air inlet and the intake grill tail end that is positioned at the impeller intake grill, the described intake grill beginning, described intake grill tail end amplified gradually to the impeller bodies direction with the streamlined intake grill tail end that is tapered to.
The more detailed technological scheme of the utility model is: a kind of inlet clock device of blower fan, comprise intake grill beginning that is positioned at air inlet and the intake grill tail end that is positioned at the impeller intake grill, the described intake grill beginning is with the streamlined intake grill tail end that is tapered to, described intake grill tail end amplifies gradually to the impeller bodies direction, described intake grill tail end is connected with impeller bodies, makes inlet clock and impeller bodies be linked to be an integral body.
The utility model has the advantages that: the utility model the intake grill beginning with the streamlined intake grill tail end that is tapered to, the intake grill tail end amplifies gradually to the impeller bodies direction again, and be connected with impeller bodies, make inlet clock and impeller bodies be linked to be an integral body, thereby it is more smooth that gas is entered, and then the raising fan efficiency, reduce noise.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is a sectional view of the present utility model.
Wherein: 1 air port beginning; 2 air port tail ends; 3 impeller bodies; 4 inlet clocks.
Embodiment
Embodiment: as shown in Figure 2, a kind of inlet clock device of blower fan, comprise intake grill beginning 1 that is positioned at air inlet and the intake grill tail end 2 that is positioned at the impeller intake grill, the described intake grill beginning 1 is with the streamlined intake grill tail end 2 that is tapered to, intake grill tail end 2 amplifies gradually to impeller bodies 3 directions, and be connected with impeller bodies 3, make inlet clock 4 be linked to be an integral body with impeller bodies 3.In actual production, with the intake grill beginning 1 with the streamlined intake grill tail end 2 that is tapered to, intake grill tail end 2 amplifies gradually to impeller bodies 3 directions, and is connected with impeller bodies 3, makes inlet clock 4 be linked to be an integral body with impeller bodies 3.In actual use, because the intake grill beginning 1 is with the streamlined intake grill tail end 2 that is tapered to, and intake grill tail end 2 amplifies gradually to impeller bodies 3 directions, be connected with impeller bodies 3, make inlet clock 4 in aggregates with impeller bodies 3, thereby the gas that inlet clock 4 is entered is more smooth, and then improves fan efficiency, reduces noise.
Claims (3)
1. the inlet clock device of a blower fan comprises intake grill beginning (1) that is positioned at air inlet and the intake grill tail end (2) that is positioned at the impeller intake grill, it is characterized in that: the described intake grill beginning (1) is with the streamlined intake grill tail end (2) that is tapered to.
2. according to the inlet clock device of the described blower fan of claim 1, it is characterized in that: described intake grill tail end (2) amplifies gradually to impeller bodies (3) direction.
