Abstract

The utility model relates to a nozzle structure of a bladeless fan. The nozzle structure comprises a nozzle body, wherein the nozzle body is provided with a receiving port and an airflow channel, the receiving port is used for receiving basic airflows, the moving direction of the airflow channel is consistent with the air inlet direction of the receiving port, the surface of the nozzle body is provided with air outlets which are arranged in rows or lines along the moving direction of the airflow channel, and the basic airflows received in the airflow channel are ejected outwards from the air outlets. In the structure, the moving direction of the airflow channel is a single vertical direction, so that the uniform distribution of airflows in the channel can be promoted, and the uniformity of the airflows in the ejecting process is ensured; meanwhile, the nozzle structure is provided with two rows of side-by-side and adjacently arranged air outlets, and in the process of running, two airflows ejected through the two rows of air outlets are converged into an airflow in front of a nozzle, so that the ejection speed of the airflow is increased, and the air supply distance is effectively improved, therefore, the purpose of rapidly cooling users can be achieved.

Description

A kind of nozzle arrangements without blade fan

Technical field:

The utility model relates to fan art, particularly a kind of nozzle arrangements without blade fan.

Background technique:

At present, design without blade fan nozzle is ring nozzle mostly, it is provided with for receiving the annular pass of basic air-flow and for spraying the annular row gas port of basic air-flow, is also provided with near the annular opening for outside air being guided to annular row gas port, mixing with the basic air-flow spraying from annular row gas port.When user uses, there is following shortcoming in this structure nozzle:

1, the design of annular pass makes basic air-flow in the trend of nozzle interior ringwise, easily like this causes air-flow skewness in passage, and then affects the uniformity of jet-impingement.

2, the basic air-flow spraying from annular row gas port relatively disperses, does not concentrate, and makes when using relatively at a distance (for example 3 meters), and the air-flow velocity producing from nozzle is low, and air-supply effect is undesirable, does not reach fast nice and cool user's object.

3, the forward and backward openings of sizes of annular opening is substantially etc. large, the suction of dragging that causes basic air-flow that the air-flow velocity of outside air when by this annular opening depend on that annular row gas port sprays completely, therefore be difficult to generate high velocity air and mix with the basic air-flow of injection, thereby affect air quantity.

4, the existing large problem of ubiquity noise while using without blade fan, particularly, when needs fan provides high velocity air, the noise that the impeller High Rotation Speed of fan component cutting air produces is particularly outstanding, greatly affects Environmental Conditions.

5, the utilization area taking is large, is unfavorable for putting and deposits etc.

Model utility content:

The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of and can guarantee that jet-impingement is even, and accelerate jet-impingement speed, raising air quantity and air supplying distance, and reduce noise, dwindles the nozzle arrangements without blade fan of occupation area.

For reaching above object, the utility model is realized by lower technological scheme:

A kind of nozzle arrangements without blade fan, comprise nozzle body, described nozzle body is provided with for receiving receiving port and the air-flow path of basic air-flow, the trend of described air-flow path is consistent with the airintake direction of described receiving port, described nozzle body surface is provided with the relief opening of or one-tenth column distribution in a row along described air-flow path trend, and the basic air-flow receiving in described air-flow path outwards sprays from described relief opening.

Preferably, described receiving port is located at nozzle body bottom, and described air-flow path is separated into two vertical air-flow paths that are positioned at both sides, receiving port upper end by a separate space.Described relief opening is provided with two row, corresponding with described two vertical air-flow paths respectively; And described two row relief openings side by side and close on setting.Described separate space is the middle chamber of an inswept opening, the wide opening in rear end, and the inswept opening of described separate space is just in time between described two row relief openings.In described separate space, two relative side surfaces form two air flow guide surface that outside air is guided, and construct a cross section and be substantially trumpet-shaped air-flow guidance field between two air flow guide surface.The wide A/F in rear end of described separate space is 1～16 times of inswept A/F, and the spacing between described two row relief openings is 2～150mm.

Inferior choosing, described receiving port is located at nozzle body bottom, and described air-flow path is located at receiving port upper end and is vertically connected with receiving port.Described relief opening is provided with two row, and the spacing between two row relief openings is 2～150mm.

Further, described relief opening is formed by some compartments etc. minute by strip rectangular aperture.

Further, described nozzle body is set to circular cylindrical cavity.

The beneficial effects of the utility model are:

First, the air-flow path of nozzle is set to the vertical passageway that trend is consistent with receiving port airintake direction, making the trend of air-flow in passage is single vertical direction, can promote like this air-flow being uniformly distributed in passage, and then the uniformity while guaranteeing jet-impingement.

Secondly, there are two row side by side and close on the relief opening of setting, during work, two strands of air-flows that eject by this two row relief opening, merge into one air-flow in the place ahead of nozzle, have accelerated the jet velocity of air-flow, improve effective air supplying distance, can realize fast nice and cool user's object., compare with existing ring nozzle meanwhile, when motor speed equates, can increase air output, equal air output can reduce motor revolution, cuts air and the noise that produces while reducing impeller High Rotation Speed.

Moreover, air-flow guidance field inswept, the wide horn-like structure in rear end, can guiding outside air by play multiplication air-flow velocity effect, the air that can effectively attach nozzle periphery generates high velocity air, and guide and concentrate between two row relief openings, mix with the basic air-flow ejecting from relief opening together and carry fast forward, not only accelerated the jet velocity of air-flow, improve air quantity, and can also keep the equalization stable of air-flow output.

Finally, without blade fan designs of nozzles, be roughly cylinder type, the utilization area taking is in use little, saves usage space, and convenient for collecting, saves parking space.
