Abstract
The invention discloses a double-end air suction assembly which comprises a casing and an air suction fan arranged in the casing. The double-end air suction assembly is characterized in that a first air way and a second air way are further arranged in the casing; an annular protruding portion is arranged on the middle portion of the casing, an air inlet channel is arranged in the annular protruding portion, a mesh plate serving as an air inlet hole is arranged at the position of an inlet of the air inlet channel, a first air way outlet is arranged at the left end of the casing, and a second air way outlet is arranged at the right end of the casing. The double-end air suction assembly can discharge air bidirectionally; air is sucked from the position of the mesh plate with small hole diameter and discharged from a small external narrow air outlet hole by arranging fan blades insides, fingers of children cannot be inserted into the assembly, and therefore the double-end air suction assembly has good safety.
Description
Technical field
The invention belongs to the fan structure design field, be specifically related to a kind of double end air draught assembly.
Background technique
At present commercially available without the blade profile Safety far, comprise base and be arranged on the annular air-out face shield on base, in base, be provided with that to take the turbo type blower fan be main air draught assembly; The great advantage of this fan is due to the traditional electrical fan flabellum used of having forgone, thereby no matter to the adult or the child all has fabulous Security.But this fan also has the following disadvantages: for fear of huge too fat to move, adopt the base of small diameter, so limited the size of turbo type blower fan, in order to guarantee enough air outputs, the rotating speed of turbo type blower fan is higher, generally reach the per second hundreds of to thousands of turning, cause noise very large, and be difficult to eradicate; In addition, because the diameter of turbo type blower fan is too little, although its rotating speed is very high, air output still can not be compared with conventional fan, the blowing poor effect.
Summary of the invention
The purpose of this invention is to provide a kind of double end air draught assembly that can the twocouese air-out.
The technological scheme that realizes the object of the invention is: a kind of double end air draught assembly comprises housing, is arranged on the suction fan in housing; Its structural feature is in housing also to be provided with the first air channel and the second air channel; The middle part of housing is provided with cyclic lug, is provided with air intake passage in this cyclic lug, and the ingress of this air intake passage is provided with the mesh plate as intake opening, and the left end of housing is provided with the first ducting outlet, and the right-hand member of housing is provided with the second ducting outlet.
In such scheme, suction fan comprises double end motor and two air draught impellers, and during the double end electric machine rotation, air enters from the mesh plate at housing middle part, after a corresponding air draught impeller, enters into the first air channel and the second air channel.
The present invention can the twocouese air-out, in addition by built-in flabellum, and the very little mesh plate air draught from aperture, from air-out external very little air-out slot, children's finger is slotting does not enter, so also have Security preferably.
The accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is a kind of application schematic diagram of double end air draught assembly shown in Figure 1.
