Abstract
The utility model relates to the technical field of bladeless fans, in particular to an air outlet structure of a bladeless fan. The structure of the bladeless fan comprises a big rear cover, a big front cover, a small rear cover and a small front cover. An air inlet is formed on the bottom of the big rear cover. The big rear cover is connected with the big front cover in a butt joint mode so as to form a big air-channel. The small rear cover is connected with the small front cover in a butt joint mode so as to form a small air-channel. The big air-channel is communicated with the small air-channel. The big front cover is provided with an annular air outlet A and the annular air outlet A is communicated with the big air-channel. The small front cover is provided with an annular air outlet B and the annular air outlet B is communicated with the small air-channel. The air outlet structure of bladeless fan is simple in structure, reasonable in arrangement and low in processing difficulty. The air outlet structure of the bladeless fan can efficiently solve a single air direction problem of the air outlet in the prior art.
Description
Technical field
The utility model relates to without the blade fan technical field, particularly a kind of air outlet structure without blade fan.
Background technique
There is larger potential safety hazard in the blade of conventional fan,, arises at the historic moment without blade fan for this reason.By host shell, be located at the exhaust outlet on the host shell without blade fan, be located at successively from top to bottom the motor in the host shell, pass through wheel fan blade and circuit mainboard and form.Existing exhaust outlet without blade fan only has one, formed by front shroud and back cover docking, and exhaust outlet is located at the joint of front shroud and back cover, arrange like this, exist the exhaust outlet wind direction single, the more high defective of difficulty of processing and deficiency are therefore be necessary existing air outlet structure without blade fan is improved.
The model utility content
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of simple in structure, and rational air outlet structure without blade fan is set.
For achieving the above object, the utility model is by the following technical solutions:
A kind of air outlet structure without blade fan described in the utility model, comprise large back cover, large front shroud, little back cover, little front shroud, described large back cover bottom is provided with intake grill, and described large back cover and large front shroud docking form wind trunk, described little back cover and the docking of little front shroud form little air channel, and described wind trunk is communicated with little air channel; Described large front shroud is provided with annular exhaust outlet A, and annular exhaust outlet A is communicated with wind trunk, and described little front shroud is provided with annular exhaust outlet B, and annular exhaust outlet B is communicated with little air channel.
Further, described large front shroud is provided with tracheae A, and tracheae A is communicated with wind trunk, and described little back cover is provided with tracheae B, and tracheae B is communicated with little air channel, and described tracheae A is connected connection with tracheae B.
Further: described annular exhaust outlet A and annular exhaust outlet B homonymy arrange.
The utility model beneficial effect is: the utility model is provided with annular exhaust outlet A and annular exhaust outlet B simultaneously, efficiently solves the single deficiency of prior art exhaust outlet wind direction; Described annular exhaust outlet A and annular exhaust outlet B are located at respectively on large front shroud and the little front shroud, and processing is simple, and fabricating cost is low, efficiently solves prior art and exhaust outlet is located at the joint of front shroud and back cover and is caused difficulty of processing high, the defective that fabricating cost is high.
