Abstract
The invention discloses a double-end air outlet face cover which comprises two symmetrical air outlet face covers. Each air outlet face cover comprises a face plate and a back plate, narrow air outlet holes are formed in the face plates, installation holes are formed in the center of the back panels, and air guide channels are arranged between the face plates and the back plates. As same as the traditional bladeless fan, blades can be arranged insides and cannot be seen from the outside, air is sucked from the position of a mesh plate with small hole diameter and is discharged from the tiny narrow air outlet holes, fingers of children cannot be inserted into the double-end air outlet face cover, and therefore the double-end air outlet face cover 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-out face shield.
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 safer reliable double end air-out face shield.
The technological scheme that realizes the object of the invention is: a kind of double end air-out face shield, comprise symmetrically arranged two air-out face shields, each air-out face shield comprises panel and backboard, and panel is provided with the air-out slot, the backboard center is provided with mounting hole, is provided with air-guiding aisle between panel and backboard.
In such scheme, two backboards enclose the air intake passage that forms an annular, and the ingress of this air intake passage is provided with mesh plate.
In such scheme, the shape of each air-out slot is arc shaped.
In such scheme, the air-out slot is arranged in ring-type in the front of each air-out face shield.
The present invention is the same without blade fan with tradition, can be built-in flabellum, and outside be can't see, the very little mesh plate air draught from aperture, from air-out very little air-out slot, children's finger is inserted not to enter, so 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-out face shield shown in Figure 1.
Embodiment
