Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

The utility model discloses a cyclone generator.

As shown in fig. 1 to 5, the cyclone generator includes a generating pipe 1, the generating pipe 1 includes an air inlet 2 and an air outlet 3, the air outlet 3 is connected with the air pumping pipe in a sealing manner, and the generating pipe 1 is contracted at one end close to the air inlet 2 to form a contraction port 4.

In addition, a tangential air inlet 5 is formed in the position of the contraction opening 4 of the generation pipeline 1, an air supply pipe 6 corresponding to the tangential air inlet 5 is integrally formed in the position of the contraction opening 4 of the generation pipeline 1, and the air supply pipe 6 is used for being connected with an air source and introducing air into the tangential air inlet 5.

The number of the tangential air inlets 5 is at least two, and the tangential air inlets 5 are distributed on the generating pipeline 1 in a circumferential manner.

Specifically, the number of the tangential air inlets 5 is two, and the two tangential air inlets 5 are symmetrical with respect to the center.

During the use, must guarantee that the tolerance that tangential air inlet 5 sent into to constriction 4 is less than the tolerance that gas outlet 3 sent out, and the gas pressure that tangential air inlet 5 department sent into is high, guarantees to produce whirlwind in 2 departments of air inlet, forms the whirlwind passageway, and the gaseous velocity of flow is fast in the passageway, and the pressure differential of the upper and lower side of passageway is great, and in the passageway and pressure differential all around are less, effectively reduces 2 outside gushing into of gas around of air inlet, increases the effect distance of breathing in.

In the present invention, the generating pipe 1 is a rotating body structure, and the material of the generating pipe 1 is not required, and may be made of metal or plastic, which will not be described herein too much.

The form of the auxiliary inlet 2 for generating the cyclone is not limited to circular, rectangular, trapezoidal, slit, multi-inlet 2, etc. other shapes are based on different applications of the same principle.

In the utility model, the generating pipeline 1 is a Laval nozzle, a tangential air inlet 5 is added at the divergent position of the nozzle, and auxiliary airflow with relatively high pressure and relatively small flow is introduced, thus being beneficial to the generation of cyclone; the flow is small, and the influence on the suction capacity of the main pipeline is reduced.

High-pressure gas is tangentially sprayed into the Laval nozzle, and is accelerated to diffuse towards the gas outlet 3 while rotating, so that cyclone is formed in the Laval nozzle, and certain suction capacity is achieved. The gas rotary motion of air inlet 2 forms the whirlwind passageway, and the gaseous velocity of flow is fast in the passageway, and the pressure differential of the upper and lower side of passageway is great, and in the passageway and pressure differential all around are less, effectively reduces 2 outside gushing into of surrounding gas of air inlet, increase the effect distance of breathing in.

The specific implementation principle of the utility model is as follows:

according to the utility model, the cyclone is generated in the generating pipeline 1, the gas in the gas inlet 2 rotates to form a cyclone channel, the gas flow speed in the channel is high, the pressure difference between the upper part and the lower part of the channel is large, the pressure difference between the inside and the periphery of the channel is small, the inflow of the surrounding gas outside the gas inlet 2 is effectively reduced, and the suction action distance is increased.

The utility model also discloses a dust collector. The dust collector comprises the cyclone generator, high-pressure gas is tangentially sprayed into the generator, and the high-pressure gas is accelerated to diffuse towards the gas outlet 3 while rotating, so that cyclone is formed in the generating pipeline 1, and the dust collector has certain suction capacity.

At the moment, under the action of an original air extractor of the dust collector, the mass of whirlwind rushes towards the air outlet 3 at an accelerated speed, strong rotary negative pressure is formed at the air inlet 2, the whirlwind outside the air outlet is generated, and the dust collection effect is improved.

Specifically, on the basis of the original dust collector, a low-power silent air suction machine is used instead, and a low-power air compressor is added. If the existing dust collector is modified as follows: the air suction fan is replaced by a mute fan, the air volume is 220m3/h, the static pressure is 180Pa, the volume is 35-40 decibels, and the noise source is reduced; the air inlet 2 uses a miniature inflating pump, the flow rate is 0.9m3/h, the air pressure is 120kPa, and the miniature inflating pump is used as an auxiliary air source to generate cyclone.

On one hand, the power of the air aspirator can be greatly reduced, and silent dust collection is realized; on the other hand, the generated cyclone increases the dust collection distance, realizes suspended dust collection, does not need to be attached to the ground, and does not leave dead angles.

Meanwhile, the compressed air pipeline is arranged on the dust collection pipeline side by side, and the flow is small, so that potential safety hazards do not exist.

The utility model also discloses a range hood. The smoke exhaust ventilator comprises the cyclone generator, the air inlet 2 of the generation pipeline 1 is inwards bent to form a liquid accumulation groove 7, the bending angle is larger than 90 degrees, and the bending part is arranged in an arc shape.

At the moment, under the action of the original air extractor of the range hood, the group of whirlwind sped up towards the air outlet 3, strong rotary negative pressure is formed at the air inlet 2, the whirlwind outside the air outlet is generated, and the oil smoke absorption effect is improved.

In addition, the use of hydrops groove 7, after smoke ventilator stopped, the fluid of generating pipeline 1 inner wall accumulated oil and drips, under the effect of gravity, can be along generating pipeline 1 inner wall landing to hydrops groove 7 in collect.
