Abstract

The utility model relates to an air volume expander which comprises a pipe-shaped body 1. An air sucking pipe 6 is arranged on one side of the pipe-shaped body 1; a front end opening 14 is an air outlet. The position of the air sucking pipe 6 corresponding to a pipe chamber of the pipe-shaped body 1 is provided with a containing chamber 4; the front end of an air inlet pipe 3 of which the front end is provided with annular spraying nozzles 2 is positioned on the back part of the pipe-shaped body 1. The air volume expander can be used for conversing an air source with high air pressure and small air quantity into the air source with low air pressure and big air quantity. The utility model has the advantages of simple structure and reliable performance.

Description

Air increase-volume device

Technical field

The utility model relates to the mechanical device that can make the air increase-volume.

Background technique

In the prior art, the blast and the air quantity of existing blower fan are all determined, in the time will using the source of the gas of less blast and big air quantity, will be disposed suitable blower fan in addition, so just have the waste of resource, can't obtain best parameter simultaneously.

The model utility content

The technical problems to be solved in the utility model is, defective at prior art exists proposes a kind of air increase-volume device, and it can be converted to the source of the gas of higher blast and less air quantity the source of the gas of low blast and big air quantity, thereby give full play to the utilization ratio of blower fan, saving equipment.

Technical solution of the present utility model is, described air increase-volume device has tubular body, its structural feature is, described tubular body one side is provided with exhaust tube and front port is an exhaust outlet, the tube chamber of the tubular body of position, described exhaust tube place correspondence is a containing room, and the front end that front end is equipped with the suction tude of ring-type nozzle is positioned at the tube chamber rear end of tubular body.

Below make and further specifying.

Referring to Fig. 1, the utility model has tubular body 1, its structural feature is, described tubular body 1 one sides are provided with exhaust tube 6 and front port 14 is exhaust outlet, the tube chamber of the tubular body 1 of position, described exhaust tube 6 place correspondence is a containing room 4, and the front end that front end is equipped with the suction tude 3 of ring-type nozzle 2 is positioned at the tube chamber rear portion of described tubular body 1.During actual the use, can connect Venturi tube 5, also can connect baffler 7 in exhaust tube 6 upper ends at the exhaust outlet 14 of described tubular body 1.Described ring-type nozzle 2 can adopt the prior art structure.

Working principle of the present utility model is (referring to Fig. 1), and the rear end of suction tude 3 is communicated with blower fan outlet, and the wind of being sent by blower fan is by arrow A among Fig. 1 ₁Direction sprays from its front end after entering ring-type nozzle 2 again, and its jet action makes the exhaust tube port of containing room 4 one sides form negative pressure, and it makes outside air by arrow A among Fig. 1 ₂Direction is sucked after exhaust tube 6 enters containing room 4, gas by annular nozzle 2 ejections enters the 4 back pressure reductions of the bigger containing room of volume, containing room 4 receives exhaust tube 6 inhaled airs again and air quantity is increased, send from exhaust outlet 14 then, make the source of the gas of higher blast and less air quantity be converted to the source of the gas that hangs down blast and big air quantity.

As known from the above, the utility model is a kind of air increase-volume device, and it can make the low blast of source of the gas conversion of higher blast and less air quantity and the source of the gas of big air quantity, and simple in structure, reliable performance.
