Description
Technical field：
The present invention relates to fan art, particularly a kind of nozzle of bladeless fan.
Background technology：
At present, the design of bladeless fan nozzle is nozzle ring mostly, is equipped with and leads to for receiving the annular of basic air-flow
Road and the annular vent mouth for spraying basic air-flow, be additionally provided with for guiding extraneous air to annular vent mouth, with
The annular opening of basic air-flow mixing sprayed from annular vent mouth.The structure nozzle has the disadvantage that when users use：
1st, the basic air-flow relative distribution that sprays from annular vent mouth is not concentrated so that relatively it is remote use when (example
Such as 3 meters), the air-flow velocity generated from nozzle is low, and air-supply effect is undesirable, and the purpose of quick nice and cool user is not achieved.
2nd, the forward and backward openings of sizes of annular opening is substantially etc. big, leads to gas of extraneous air when by the annular opening
The basic air-flow that stream flow velocity depends entirely on the injection of annular vent mouth drags suction, and therefore, it is difficult to generate high-speed flow and injection
Basic air-flow is mixed, so as to influence air quantity.
3rd, circular passage design so that basic air-flow nozzle interior trend in a ring, be easy to cause air-flow in this way and exist
It is unevenly distributed in channel, and then influences the uniformity of jet-impingement.
4th, the problem of generally existing noise is big when existing bladeless fan uses ought particularly need fan to provide high-speed flow
When, the noise that the impeller high speed rotation cutting air of fan component generates is especially prominent, largely effects on use environment.
5th, the usable floor area occupied is big, is unfavorable for putting and store.
Invention content：
It is an object of the invention to overcome the deficiency of the above-mentioned prior art, it is small to provide a kind of usable floor area of occupancy, can add
Fast jet-impingement speed improves air quantity and air supplying distance, and reduce noise, optimizes the nozzle of the bladeless fan of use environment.
To achieve the above objectives, the present invention is realized by lower technical solution：
A kind of nozzle of bladeless fan, including nozzle body, the nozzle body is equipped with to receive connecing for basic air-flow
Close up and inner passage, the nozzle body be additionally provided with for guide extraneous air by air guiding port, the air draws
The front end for leading mouth is equipped with a strip narrow opening, and the rear end of the air guiding port is equipped with a width and is more than strip narrow opening
Width opening, the nozzle body surface are equipped with the exhaust outlet set along the strip narrow opening periphery, and the inner passage connects
The basic air-flow of receipts sprays outward from the exhaust outlet.
Preferably, the nozzle body surface can be equipped with along two row that the strip narrow opening long side both sides are set and arrange
Gas port, the two row exhaust outlet side by side and close on setting.Spacing between the two row exhaust outlet is 2~150mm, two row
Respectively the spacing between the strip narrow opening is 1~20mm to exhaust outlet.The inner passage of the nozzle body is by described
Air guiding port is separated into mutual disconnected first passage and second channel, the two row exhaust outlet respectively with first passage and the
Two channels are connected.
Secondary choosing, the nozzle body surface can also be equipped with along the strip narrow opening long side both sides and short side side
The exhaust outlet for being inverted U shape shape distribution of setting.The inner passage of the nozzle body is separated into top by the air guiding port
The first passage and second channel of connection, two side exhaust outlets being inverted U shape in the exhaust outlet of shape distribution are logical with first respectively
Road is connected with second channel, the upper side exhaust outlet being inverted U shape in the exhaust outlet of shape distribution and the top of first, second channel
Connect position connection.
Further, the section of the air guiding port is substantially in horn-like, secondly a opposite side surface forms two
The air flow guide surface guided to extraneous air.
Further, the wide opening width in rear end of the air guiding port is the 1~16 of front end strip narrow opening width
Times.
Further, the receiving port is set on nozzle body bottom, and the first passage and second channel are set as and connect
Two vertical passageways that closing in upper end is connected.
Further, the nozzle body is set as circular cylindrical cavity.
Beneficial effects of the present invention are：
First, have side by side and close on the exhaust outlet of setting, during work, two strands of air-flows being ejected by exhaust outlet,
One air-flow is merged into front of nozzle, accelerates the jet velocity of air-flow, improves effective air supplying distance, it can be achieved that quick
The purpose of nice and cool user.Meanwhile compared with existing nozzle ring, air output can be increased when motor speed is equal, it is equal
Air output can reduce motor rotations, the noise for cutting air when reducing impeller high speed rotation and generating.
Secondly, the wide horn-like structure in air guiding port inswept, rear end, can be when guiding extraneous air to pass through
Play the role of the air-flow velocity that doubles, can effectively be attached to the air generation high-speed flow of nozzle periphery, and guide sum aggregate
In between two row exhaust outlets, quick conveying forward is mixed together with the basic air-flow ejected from exhaust outlet, not only accelerates gas
The jet velocity of stream improves air quantity, and the equalization stable that air-flow can also be kept to export.
Furthermore the gas channel of nozzle is set as two vertical passageways so that the trend of air-flow in the channel is single
Vertical direction, therefore air-flow being uniformly distributed in two channels can be promoted, and then uniformity when ensuring jet-impingement.
Finally, for the design of bladeless fan nozzle substantially in cylindrical type, the usable floor area occupied when in use is small, saves using empty
Between, and it is convenient for collecting, save parking space.
