Abstract

The invention discloses a nozzle of a bladeless fan, belonging to the technical field of fans. The nozzle comprises an annular shell and an annular flow guide plate; the shell is internally provided with an air intake channel; the shell is provide with an opening which is communicated with the air intake channel; the flow guide plate is positioned in the inner ring of the shell and is fixed on the shell; an air outlet and an air outlet channel which are arranged in opposite are formed between the outer ring of the flow guide plate and the inner ring of the shell; and the opening is communicated with the air outlet channel and an air inlet channel. After air flow is blown to the opening from the air inlet channel, the air flow enters the air outlet channel, and then is blown out of the two air outlets which are arranged in opposite, thus the air flow can be blown out of a positive surface and a negative surface of the nozzle simultaneously, and the nozzle is especially suitable for occasions when people are at the positive surface and the negative surface of the fan.

Description

A kind of nozzle of on-bladed fan

Technical field

The invention belongs to the fan technical field, the concrete nozzle that relates to a kind of on-bladed fan.

Background technique

The on-bladed fan is generally all to a side air-out, and like number of patent application: 200810177844.8 disclose a kind of on-bladed fan, and the nozzle of this on-bladed fan is the housing of a circle annular; Enclosure interior is provided with air intake passage; Also be provided with the opening that a circle communicates with passage on the housing, during use, air-flow feeds in the housing; In the entering air intake passage, blow out via opening again.The opening of this nozzle generally can only be towards a side.What wind-force can influence is limited in scope, at some many and also disperse in, all have man-hour just can not satisfy the demands at the tow sides of fan.

Summary of the invention

The present invention is directed to deficiency of the prior art, a kind of nozzle of on-bladed fan is provided, can dry simultaneously, satisfy the demand that man-hour is all arranged at the tow sides of fan to both sides.

In order to solve the problems of the technologies described above; The present invention is able to solve through following technical proposals: a kind of nozzle of on-bladed fan, comprise the annular housing of a circle, and said enclosure interior is provided with air intake passage; Said housing is provided with the opening that communicates with said air intake passage; Also comprise the guide plate of a circle annular, said guide plate is positioned at the inner ring of said housing, and said guide plate is fixed on the said housing; Form the air-out passage with two exhaust outlets that are oppositely arranged, said air-out passage of said open communication and said air intake passage between the outer ring of said guide plate and the inner ring of said housing.After air-flow blows out opening from air intake passage, get into the air-out passage, from two exhaust outlets that are oppositely arranged, blow out then, air-flow can be simultaneously blows out from the tow sides of nozzle like this, the occasion when being particluarly suitable for some fan tow sides and all the people being arranged.

In the technique scheme, the concrete a kind of guide plate and the means of fixation of housing do, also comprises link, and said link one end is fixed on the said housing, and the other end of said link is fixed on the said guide plate.The link here can be plate or bar.

In the technique scheme, the means of fixation of another kind of guide plate and housing does, also comprises screw bolt and nut, and said bolt passes after said housing and the said guide plate and said nut bolt.This mode guide plate can be dismantled.

In the technique scheme, the inner ring of preferred said housing is positioned at the diameter minimum at said opening two ends, becomes big gradually to the housing two ends.Help like this spreading from the air-flow that exhaust outlet blows out.

The invention has the beneficial effects as follows: after air-flow blows out opening from air intake passage; Get into the air-out passage; From two exhaust outlets that are oppositely arranged, blow out then, air-flow can be simultaneously blows out from the tow sides of nozzle like this, the occasion when being particluarly suitable for some fan tow sides and all the people being arranged.

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

Embodiment 1, and referring to Fig. 1 to Fig. 3, a kind of nozzle of on-bladed fan comprises thehousing 1 of a circle annular, theguide plate 2 and thelink 4 of annular, andhousing 1 inside formsair intake passage 11, and the bottom ofhousing 1 is provided with theopening 12 that communicates with air intake passage 11.The inner ring ofhousing 1 is positioned at the diameter minimum at two ends, opening 12 place, becomes gradually greatly to housing 1 two ends, is " v " font.The middle part ofhousing 1 inner ring forms the opening 12 of a circle annular that communicates withair intake passage 11;Guide plate 2 is positioned at the inner ring ofhousing 1; Form the air-outpassage 21 with two exhaust outlets that are oppositely arranged 211,212 between the inner ring of the outer ring ofguide plate 2 andhousing 1, opening 12 is communicated with air-outpassage 21 and air intake passage 11.The outer ring ofguide plate 2 is made up of with thearc transition face 24 that is connected these tworound table surface 22,23 tworound table surface 22,23, and whereinarc transition face 24 is positioned at opening 12 over against locating, and guarantees the mild transition of air-flow that blows out from opening 12;Round table surface 22,23 is parallel respectively withhousing 1 inner ring that is positioned at opening 12 both sides, guarantees that the width of air-outpassage 21 is consistent everywhere, guarantees the smooth and easy of air-flow.

Present embodiment adopts rod member aslink 4, realizes being connected betweenguide plate 2 and the housing 1.Rod member one end is fixed onair intake passage 11 inwalls, and the other end of rod member is fixed on thearc transition face 24 ofguide plate 2 after passing opening 12.
